+# You can use the lexers that come with context and athat are meant for scite also for notepad++. On
+# my machine I always install such a portable program in c:\data\system\notepadplusplus (avoiding
+# funny characters).
+#
+# (1) Download a version of scintillua++ that matches the current version if notepad++ and unzip
+#     the archive in a temporary place.
+#
+#     c:\data\notepadplusplus\*
+#
+# (2) Copy these two dlls::
+#
+#     c:\data\notepadplusplus\plugins\Scintillua++.dll
+#     c:\data\notepadplusplus\plugins\Config\Scintillua++\LexLPeg.dll
+#
+# (3) Copy this file to:
+#
+#     c:\data\notepadplusplus\plugins\Config\Scintillua++.ini
+#
+# (4) Copy the files from the texmf/context/data/scite/context so that you get:
+#
+#     c:\data\notepadplusplus\plugins\Config\data\scite-context-data-*.lua
+#     c:\data\notepadplusplus\plugins\Config\themes\scite-context-theme.lua
+#     c:\data\notepadplusplus\plugins\Config\themes\lexer.lua
+#     c:\data\notepadplusplus\plugins\Config\themes\scite-context-lexer.lua
+#     c:\data\notepadplusplus\plugins\Config\themes\scite-context-lexer-*.lua
+#
+# Now you should get the standard context lexing for the file types mentioned below. I might add a few
+# more (consistent) lexers. Beware: we don't use the lexer.lua file that ships with scintillua++. Among
+# the reasons is that when I first played with this variant of lexing the scintillua implementation was
+# quite slow, so I redid the code with some agressive optimization (in context a good test file is the
+# character database file. There is still room for improvement. One problem with the lua lexer is that
+# there is not much communication possible so that getting the state involves guesswork.
+#
+# Also, we already had lpeg based lexing in context so it made more sense to find some common ground so
+# that I could share code (a bit of a hybrid approach). There are some extra features like showing
+# invisible spaces and most noticeably spell checking (for more info see the manual).
+#
+# The lexer assumes that you have the dejavu mono fonts installed. These cover a wide repertoire of
+# characters. Some features offered for scite won't be available because no additional menu items etc
+# are defined.
+#
+# In due time some more configuration files will be added for notepad++. Maybe some more can be set up
+# below.

+-- We started using lpeg lexing as soon as it came available. Because we had rather
+-- demanding files and also wanted to use nested lexers, we ended up with our own
+-- variant. At least at that time this was more robust and also much faster (as we
+-- have some pretty large Lua data files and also work with large xml files). As a
+-- consequence successive versions had to be adapted to changes in the (at that time
+-- still unstable) api. In addition to lexing we also have spell checking and such.
+-- Around version 3.60 things became more stable so I don't expect to change much.
+--
+-- LEXING
+--
+-- When pc's showed up we wrote our own editor (texedit) in MODULA 2. It was fast,
+-- had multiple overlapping (text) windows, could run in the at most 1M memory at
+-- that time, etc. The realtime file browsing with lexing that we had at that time
+-- is still on my current wish list. The color scheme and logic that we used related
+-- to the logic behind the ConTeXt user interface that evolved.
+--
+-- Later I rewrote the editor in perl/tk. I don't like the perl syntax but tk
+-- widgets are very powerful and hard to beat. In fact, TextAdept reminds me of
+-- that: wrap your own interface around a framework (tk had an edit control that one
+-- could control completely not that different from scintilla). Last time I checked
+-- it still ran fine so I might try to implement something like its file handling in
+-- TextAdept.
+--
+-- In the end I settled for SciTE for which I wrote TeX and MetaPost lexers that
+-- could handle keyword sets. With respect to lexing (syntax highlighting) ConTeXt
+-- has a long history, if only because we need it for manuals. Anyway, in the end we
+-- arrived at lpeg based lexing (which is quite natural as we have lots of lpeg
+-- usage in ConTeXt). The basic color schemes haven't changed much. The most
+-- prominent differences are the nested lexers.
 --
--- STATUS
+-- In the meantime I made the lexer suitable for typesetting sources which was no
+-- big deal as we already had that in place (ConTeXt used lpeg from the day it
+-- showed up so we have several lexing options there too).
 --
--- todo: maybe use a special stripped version of the dll (stable api)
--- todo: play with hotspot and other properties
--- wish: access to all scite properties and in fact integrate in scite
--- todo: add proper tracing and so .. not too hard as we can run on mtxrun
--- todo: get rid of these lexers.STYLE_XX and lexers.XX (hide such details)
+-- Keep in mind that in ConTeXt (typesetting) lexing can follow several approached:
+-- line based (which is handy for verbatim mode), syntax mode (which is nice for
+-- tutorials), and tolerant mode (so that one can also show bad examples or errors).
+-- These demands can clash.
 --
 -- HISTORY
 --
+-- The remarks below are more for myself so that I keep track of changes in the
+-- way we adapt to the changes in the scintillua and scite.
+--
 -- The fold and lex functions are copied and patched from original code by Mitchell
--- (see lexer.lua). All errors are mine. The ability to use lpeg is a real nice
--- adition and a brilliant move. The code is a byproduct of the (mainly Lua based)
--- textadept (still a rapidly moving target) that unfortunately misses a realtime
--- output pane. On the other hand, SciTE is somewhat crippled by the fact that we
--- cannot pop in our own (language dependent) lexer into the output pane (somehow
--- the errorlist lexer is hard coded into the editor). Hopefully that will change
--- some day.
+-- (see lexer.lua) in the scintillua distribution. So whatever I say below, assume
+-- that all errors are mine. The ability to use lpeg in scintilla is a real nice
+-- addition and a brilliant move. The code is a byproduct of the (mainly Lua based)
+-- TextAdept which at the time I ran into it was a rapidly moving target so I
+-- decided to stick ot SciTE. When I played with it, it had no realtime output pane
+-- although that seems to be dealt with now (2017). I need to have a look at it in
+-- more detail but a first test again made the output hang and it was a bit slow too
+-- (and I also want the log pane as SciTE has it, on the right, in view). So, for
+-- now I stick to SciTE even when it's somewhat crippled by the fact that we cannot
+-- hook our own (language dependent) lexer into the output pane (somehow the
+-- errorlist lexer is hard coded into the editor). Hopefully that will change some
+-- day. The ConTeXt distribution has cmd runner for textdept that will plug in the
+-- lexers discussed here as well as a dedicated runner. Considere it an experiment.
 --
--- Starting with SciTE version 3.20 there is an issue with coloring. As we still
--- lack a connection with SciTE itself (properties as well as printing to the log
--- pane) and we cannot trace this (on windows). As far as I can see, there are no
--- fundamental changes in lexer.lua or LexLPeg.cxx so it must be in Scintilla
--- itself. So for the moment I stick to 3.10. Indicators are: no lexing of 'next'
--- and 'goto <label>' in the Lua lexer and no brace highlighting either. Interesting
--- is that it does work ok in the cld lexer (so the Lua code is okay). Also the fact
--- that char-def.lua lexes fast is a signal that the lexer quits somewhere halfway.
--- Maybe there are some hard coded limitations on the amount of styles and/or length
--- if names.
+-- The basic code hasn't changed much but we had to adapt a few times to changes in
+-- the api and/or work around bugs. Starting with SciTE version 3.20 there was an
+-- issue with coloring. We still lacked a connection with SciTE itself (properties
+-- as well as printing to the log pane) and we could not trace this (on windows).
+-- However on unix we can see messages! As far as I can see, there are no
+-- fundamental changes in lexer.lua or LexLPeg.cxx so it must be/have been in
+-- Scintilla itself. So we went back to 3.10. Indicators of issues are: no lexing of
+-- 'next' and 'goto <label>' in the Lua lexer and no brace highlighting either.
+-- Interesting is that it does work ok in the cld lexer (so the Lua code is okay).
+-- All seems to be ok again in later versions, so, when you update best check first
+-- and just switch back to an older version as normally a SciTE update is not
+-- critital. When char-def.lua lexes real fast this is a signal that the lexer quits

+-- future versions. I'm anyway still happy with this kind of lexing.
 --
 -- In 3.31 another major change took place: some helper constants (maybe they're no
 -- longer constants) and functions were moved into the lexer modules namespace but
 -- the functions are assigned to the Lua module afterward so we cannot alias them

+-- The textadept documentation says that there can be a lexers directory under a user
+-- directory but it's not in the package path. The next involved a bit or trial and
+-- error in order to avoid crashes so I suppose it can be done better. If I use
+-- textadept alongside scite I will make a different key binding. The code below is
+-- a bit of a mess, which is a side effect of stepwise adaption combined with shared
+-- iuse of code.

+-- We use the commandline switch -u to point to the location where this file is located
+-- as we then can keep it outside the program area. We also put some other files under

+-- A problem is that scite needs the lexer.lua file while for textadept we don't want
+-- to touch that one. So we end up with duplicate files. We cannot configure scite to
+-- use an explicit lexer so both lexer paths have the same files except that the textadept
+-- one has no lexer.lua there. Unfortunately themes is not requires's but always looked
+-- up with an explicit path. (Maybe I should patch that.)

+-- You need to copy this file over lexer.lua. In principle other lexers could work too but
+-- not now. Maybe some day. All patterns will move into the patterns name space. I might do
+-- the same with styles. If you run an older version of SciTE you can take one of the
+-- archives. Pre 3.41 versions can just be copied to the right path, as there we still use
+-- part of the normal lexer.
+--
+-- REMARK
+--
+-- We started using lpeg lexing as soon as it came available. Because we had rather demanding
+-- files and also wanted to use nested lexers, we ended up with our own variant. At least at
+-- that time this was more robust and also faster (as we have some pretty large lua data files
+-- and also work with large xml files). As a consequence successive versions had to be adapted
+-- to changes in the (at that time still unstable) api. In addition to lexing we also have
+-- spell checking and such. Around version 3.60 things became more stable so I don't expect to
+-- change much.
+--
+-- STATUS
+--
+-- todo: maybe use a special stripped version of the dll (stable api) and add a bit more
+--       interfacing to scintilla
+-- todo: investigate if we can use the already built in lua instance so that we can combine the
+--       power of lexign with extensions
+-- todo: play with hotspot and other properties (but no real need now)
+-- todo: maybe come up with an extension to the api subsystem
+-- todo: add proper tracing and so .. not too hard as we can run on mtxrun, but we lack a console
+--       for debugging (ok, chicken-egg as lexers probably need to be loaded before a console can
+--       kick in)
+-- todo: get rid of these lexers.STYLE_XX and lexers.XX (hide such details)
+--
+-- wish: access to all scite properties and in fact integrate in scite
+--
+--
+-- In the meantime I made the lexer suitable for typesetting sources which was no big deal as we
+-- already had that in place (ConTeXt used lpeg from the day it showed up so we have several lexing
+-- options there too).
+--
+-- HISTORY
+--
+-- The fold and lex functions are copied and patched from original code by Mitchell (see lexer.lua).
+-- All errors are mine. The ability to use lpeg in scintilla is a real nice addition and a brilliant
+-- move. The code is a byproduct of the (mainly Lua based) textadept (at the time I ran into it was
+-- a rapidly moving target so I decided to stick ot SciTE). When I played with it, it had no realtime
+-- output pane but that seems to be dealt with now (2017). I need to have a look at it in more detail
+-- but a first test again mad the output hang and it was a bit slow too (and I also want the log pane
+-- as scite has it, on the right, in view). So, for now I stick to SciTE even when it's somewhat
+-- crippled by the fact that we cannot hook our own (language dependent) lexer into the output pane
+-- (somehow the errorlist lexer is hard coded into the editor). Hopefully that will change some day.
+-- So, how did we arrive where we're now.
+--
+-- Starting with SciTE version 3.20 there is an issue with coloring. As we still lack a connection
+-- with SciTE itself (properties as well as printing to the log pane) and we cannot trace this (on
+-- windows). As far as I can see, there are no fundamental changes in lexer.lua or LexLPeg.cxx so it
+-- must be in Scintilla itself. So for the moment I stick to 3.10. Indicators are: no lexing of 'next'
+-- and 'goto <label>' in the Lua lexer and no brace highlighting either. Interesting is that it does
+-- work ok in the cld lexer (so the Lua code is okay). All seems to be ok again in later versions,
+-- so, when you update best check first and just switch back to an older version as normally a SciTE
+-- update is not critital. When char-def.lua lexes real fast this is a signal that the lexer quits
+-- somewhere halfway. Maybe there are some hard coded limitations on the amount of styles and/or
+-- length of names.
+--
+-- Anyway, after checking 3.24 and adapting to the new lexer tables things are okay again. So, this
+-- version assumes 3.24 or higher. In 3.24 we have a different token result, i.e. no longer a { tag,
+-- pattern } but just two return values. I didn't check other changes but will do that when I run into
+-- issues. I had optimized these small tables by hashing which was more efficient but this is no longer
+-- needed. For the moment we keep some of that code around as I don't know what happens in future
+-- versions. I'm anyway still happy with this kind of lexing.
+--
+-- In 3.31 another major change took place: some helper constants (maybe they're no longer constants)
+-- and functions were moved into the lexer modules namespace but the functions are assigned to the Lua
+-- module afterward so we cannot alias them beforehand. We're probably getting close to a stable
+-- interface now. I've considered making a whole copy and patch the other functions too as we need an
+-- extra nesting model. However, I don't want to maintain too much. An unfortunate change in 3.03 is
+-- that no longer a script can be specified. This means that instead of loading the extensions via the
+-- properties file, we now need to load them in our own lexers, unless of course we replace lexer.lua
+-- completely (which adds another installation issue).
+--
+-- Another change has been that _LEXERHOME is no longer available. It looks like more and more
+-- functionality gets dropped so maybe at some point we need to ship our own dll/so files. For instance,
+-- I'd like to have access to the current filename and other scite properties. We could then cache some
+-- info with each file, if only we had knowledge of what file we're dealing with.
+--
+-- For huge files folding can be pretty slow and I do have some large ones that I keep open all the time.
+-- Loading is normally no ussue, unless one has remembered the status and the cursor is at the last line
+-- of a 200K line file. Optimizing the fold function brought down loading of char-def.lua from 14 sec
+-- => 8 sec. Replacing the word_match function and optimizing the lex function gained another 2+ seconds.
+-- A 6 second load is quite ok for me. The changed lexer table structure (no subtables) brings loading
+-- down to a few seconds.
+--
+-- When the lexer path is copied to the textadept lexer path, and the theme definition to theme path
+-- (as lexer.lua), the lexer works there as well. Although ... when I decided to check the state of
+-- textadept i had to adapt some loader code. It's not pretty but works and also permits overloading.
+-- When I have time and motive I will make a proper setup file to tune the look and feel a bit and
+-- associate suffixes with the context lexer. The textadept editor has a nice style tracing option but
+-- lacks the tabs for selecting files that scite has. It also has no integrated run that pipes to the
+-- log pane. Interesting is that the jit version of textadept crashes on lexing large files (and does
+-- not feel faster either; maybe a side effect of known limitations as we know that luajit is more
+-- limited than stock lua). Btw, in the meantime on unix one can test easier as there we can enable
+-- the loggers in this module.
+--
+-- Function load(lexer_name) starts with _lexers.WHITESPACE = lexer_name .. '_whitespace' which means
+-- that we need to have it frozen at the moment we load another lexer. Because spacing is used to revert
+-- to a parent lexer we need to make sure that we load children as late as possible in order not to get
+-- the wrong whitespace trigger. This took me quite a while to figure out (not being that familiar with
+-- the internals). The lex and fold functions have been optimized. It is a pitty that there is no proper
+-- print available. Another thing needed is a default style in our own theme style definition, as otherwise
+-- we get wrong nested lexers, especially if they are larger than a view. This is the hardest part of
+-- getting things right.
+--
+-- It's a pitty that there is no scintillua library for the OSX version of scite. Even better would be
+-- to have the scintillua library as integral part of scite as that way I could use OSX alongside
+-- windows and linux (depending on needs). Also nice would be to have a proper interface to scite then
+-- because currently the lexer is rather isolated and the lua version does not provide all standard
+-- libraries. It would also be good to have lpeg support in the regular scite lua extension (currently
+-- you need to pick it up from someplace else).
+--
+-- With 3.41 the interface changed again so it gets time to look into the C++ code and consider compiling
+-- and patching myself. Loading is more complicated now as the lexer gets loaded automatically so we have
+-- little control over extending the code now. After a few days trying all kind of solutions I decided to
+-- follow a different approach: drop in a complete replacement. This of course means that I need to keep
+-- track of even more changes (which for sure will happen) but at least I get rid of interferences. The
+-- api (lexing and configuration) is simply too unstable across versions. Maybe in a few years things have
+-- stabelized again. (Or maybe it's not really expected that one writes lexers at all.) A side effect is
+-- that I now no longer will use shipped lexers but just the built-in ones in addition to the context
+-- lpeg lexers. Not that it matters much as the context lexers cover what I need (and I can always write
+-- more).
+--
+-- In fact, the transition to 3.41 was triggered by an unfateful update of Ubuntu which left me with an
+-- incompatible SciTE and lexer library and updating was not possible due to the lack of 64 bit libraries.
+-- We'll see what the future brings.
+--
+-- Promissing is that the library now can use another Lua instance so maybe some day it will get properly
+-- in SciTE and we can use more clever scripting.
+--
+-- In some lexers we use embedded ones even if we could do it directly, The reason is that when the end
+-- token is edited (e.g. -->), backtracking to the space before the begin token (e.g. <!--) results in
+-- applying the surrounding whitespace which in turn means that when the end token is edited right,
+-- backtracking doesn't go back. One solution (in the dll) would be to backtrack several space categories.
+-- After all, lexing is quite fast (applying the result is much slower).
+--
+-- For some reason the first blob of text tends to go wrong (pdf and web). It would be nice to have 'whole
+-- doc' initial lexing. Quite fishy as it makes it impossible to lex the first part well (for already opened
+-- documents) because only a partial text is passed.
+--
+-- So, maybe I should just write this from scratch (assuming more generic usage) because after all, the dll
+-- expects just tables, based on a string. I can then also do some more aggressive resource sharing (needed
+-- when used generic).
+--
+-- I think that nested lexers are still bugged (esp over longer ranges). It never was robust or maybe it's
+-- simply not meant for too complex cases (well, it probably *is* tricky material). The 3.24 version was
+-- probably the best so far. The fact that styles bleed between lexers even if their states are isolated is
+-- an issue. Another issus is that zero characters in the text passed to the lexer can mess things up (pdf
+-- files have them in streams).
+--
+-- For more complex 'languages', like web or xml, we need to make sure that we use e.g. 'default' for
+-- spacing that makes up some construct. Ok, we then still have a backtracking issue but less.
+--
+-- Good news for some ConTeXt users: there is now a scintillua plugin for notepad++ and we ship an ini
+-- file for that editor with some installation instructions embedded.
+--
+-- TODO
+--
+-- I can make an export to context, but first I'll redo the code that makes the grammar,
+-- as we only seem to need
+--
+--   lexer._TOKENSTYLES : table
+--   lexer._CHILDREN    : flag
+--   lexer._EXTRASTYLES : table
+--   lexer._GRAMMAR     : flag
+--
+--   lexers.load        : function
+--   lexers.lex         : function
+--
+-- So, if we drop compatibility with other lex definitions, we can make things simpler. Howeverm in the
+-- meantime one can just do this:
+--
+--    context --extra=listing --scite [--compact --verycompact] somefile.tex
+--
+-- and get a printable document. So, this todo is obsolete.
+
+-- TRACING
+--
+-- The advantage is that we now can check more easily with regular Lua(TeX). We can also use wine and print
+-- to the console (somehow stdout is intercepted there.) So, I've added a bit of tracing. Interesting is to
+-- notice that each document gets its own instance which has advantages but also means that when we are
+-- spellchecking we reload the word lists each time. (In the past I assumed a shared instance and took
+-- some precautions.)
+
+-- todo: make sure we don't overload context definitions when used in context
+
+-- properties is an ugly mess ... due to chages in the interface we're now left with some hybrid
+-- that sort of works ok

+-- as we don't want to clash with existing files, we end up in

+-- This is an adapted version of the run code by mitchell.att.foicica.corunner. The main
+-- reason I started patching is that long lines got broken in the middle so we needed
+-- to have a more clever line splitter that saves half of a line for later. Then I
+-- decided to come up with a few more variants so in the end ... it's just too tempting
+-- make something that exactly suits out needs. In fact, maybe I'll do that some day:
+-- take core textadept and make a dedicated variant for the kind of processing that we
+-- do and make it suitable for document authors (the manual says that is doable). In that
+-- case I can also use a lot of already written helpers.
+--
+-- The error scanner is not needed. If I need one, it will be using a lexers applied
+-- afterwards because working on half lines is not going to work out well anyway.
+--
+-- Here I removed iconv calls as in context we use utf (less hassle with fonts too). One
+-- can always use the original approach.
+--
+-- The events seems to have hard coded names, Also, the name of the message buffer cannot
+-- be changes because otherwise we get a message when the session is restored. I don't
+-- care about locales.
+--
+-- Somehow the process hangs when I refresh the pdf viewer, this doesn't happen in scite so
+-- the underlying code is for the moment less reliant.

+\StartItems{Some reasons to use \TEX}
+    \StartItem
+        There can be several reasons for using \TEX. Some are subjective.
+    \StopItem
+    \StartItem
+        You like the way it works: you edit a document using a simple editor,
+        add a couple of directives and delay rendering. It's the content and
+        structure that matter.
+    \StopItem
+    \StartItem
+        You need it for instance because you have to typeset math and you believe that
+        no other tool can do a better job on that.
+    \StopItem
+    \StartItem
+        You found out that it can save time because it is programmable and after all,
+        programming is a nice distraction from writing.
+    \StopItem
+    \StartItem
+        You don't want to change a 20 year old habit and why quit using something that
+        you know well by now.
+    \StopItem
+    \StartItem
+        You like an occasional fight with a batch oriented system and updating (sometimes to
+        the extend of compiling) can be done while watching a movie.
+    \StopItem
+    \StartItem
+        You dislike learning a new program every 5 years. Of course it would be different
+        if we'd live for 500 years.
+    \StopItem
+\StopItems
+
+\StartItems{My reasons to use \TEX}
+    \StartItem
+        I've always used \TEX\ and can do what I need to do with it. I like to
+        focus on what can be done instead of what can't.
+    \StopItem
+    \StartItem
+        I don't like disposable tools and am quite lucky that \TEX\ still
+        can adapt to my needs.
+    \StopItem
+    \StartItem
+        I like my job but only when using the current tools and cooking up
+        reuseable solutions.
+    \StopItem
+    \StartItem
+        I need it for rendering (often educational) content and also use it
+        for fun.
+    \StopItem
+    \StartItem
+        In the process I need to implement styles based on designs provided by
+        designers, most probably only know click and point tools but some of them
+        can think outside that box.
+    \StopItem
+\StopItems
+
+
+\StartItems{Using \TEX\ in projects}
+    \StartItem
+        Each project has at least a few challenges, the input,
+        the design, graphics, the boundary conditions, interfaces, etc.
+    \StopItem
+    \StartItem
+        In quite some cases a printed product is an afterthought and coding is
+        driven by viewing on the web.
+    \StopItem
+    \StartItem
+        Most time goes into mapping structure. Coding is done in \XML\ because
+        we can then manipulate content and publishers can reuse it.
+    \StopItem
+    \StartItem
+        Publishers often use a preselected designer and ask him/her to come
+        up with a design.
+    \StopItem
+    \StartItem
+        Chapter openings and title pages take some effort as well, especially
+        if the implementation has to be exact. For some reason design comes before
+        content so the designer has to guess.
+    \StopItem
+    \StartItem
+        Although one can try to catch bordercases it hardly pays off as the eventual
+        solutions are not that logic. Simplification is preferred over heuristics.
+    \StopItem
+    \StartItem
+        Unfortunately designers never use the fact that we can program variations and
+        and flexible solutions. On the other hand in a later stage we can quite conveniently
+        provide solutions for problems resulting in the editorial workflow.
+    \StopItem
+\StopItems
+
+\StartItems{Struggling with structure}
+    \StartItem
+        Structure in regular \TEX\ documents assumes a proper nesting of chapters,
+        sections, subsections etc.
+    \StopItem
+    \StartItem
+        In \CONTEXT\ we can clone heads and configure them independently. Often we end up with
+        tens of variants.
+    \StopItem
+    \StartItem
+        In practice numberings can intermix, for instance subsections can be numbered
+        per chapter instead of per subsection.
+    \StopItem
+    \StartItem
+        Numbers seldom run like 1 \unknown\ 1.1 \unknown\ 1.1.1 and individual components can be omitted and can
+        have different properties (font, color). This quickly becomes messy as more (unexpected)
+        structure is added.
+    \StopItem
+    \StartItem
+        It's for this reason that we now have a more complex model of resetting and synchronization
+        of states in \CONTEXT. Actually we keep adding more structure support.
+    \StopItem
+    \StartItem
+        Additional information that is used in a chapter sometimes is also used elsewhere, as
+        in tables of contents (for instance icons). Therefore in \CONTEXT\ \MKIV\ we now have
+        the possibility to let userdata travel around.
+    \StopItem
+\StopItems
+
+\StartItems{Bringing system in color}
+    \StartItem
+        When making a product line it helps if there is some systematic
+        approach in defining colors but it does not work out that way.
+    \StopItem
+    \StartItem
+        Unfortunately we can never use the colorpalet and colorgroup features
+        that have been present in \CONTEXT\ from the start.
+    \StopItem
+    \StartItem
+        Spotcolors are nice as they enforce a more systematic approach than
+        process colors. In such cases there is often some system.
+    \StopItem
+    \StartItem
+        With processcolors we often have to fight the \quotation {on my screen 0.01
+        \letterpercent\ makes a big difference} dilemma.
+    \StopItem
+    \StartItem
+        Automatically converting graphics to such color spaces can save a lot of time and
+        money.
+    \StopItem
+\StopItems
+
+\StartItems{Relations between fonts}
+    \StartItem
+        Although there is some fashion in using fonts most designs use at least
+        a few different ones.
+    \StopItem
+    \StartItem
+        Not all fonts are equally well equipped and one cannot rely too much on
+        features without testing them first. Although \OPENTYPE\ makes things
+        easier it also introduces problems due to incomplete features.
+    \StopItem
+    \StartItem
+        A macro package assumes some logic in sizes and relations but this is of no
+        use in practice. Most if the font mechanism is simply not used.
+    \StopItem
+    \StartItem
+        The same is true for interline spacing. Often some standard latin quote and
+        title is used to determine the spec. Not seldom most spacing is inconsistent.
+    \StopItem
+    \StartItem
+        It looks like justification is not wanted that much, let alone advanced features
+        like protrusion and expansion. Inter|-|character spacing is sometimes requested.
+    \StopItem
+\StopItems
+
+\StartItems{Why I still use \TEX}
+    \StartItem
+        We started making \CONTEXT\ for our own use, especially complex and demanding
+        educational documents.
+    \StopItem
+    \StartItem
+        Nowadays we stick to typesetting and as we specialize in automated processing
+        we have to operate within strict bounds.
+    \StopItem
+    \StartItem
+        We use not that many handy features as there is hardly any structure in the designs
+        we have to implement.
+    \StopItem
+    \StartItem
+        But we use quite some of the manipulative power of \CONTEXT. Also, we are able to
+        fulfil even the most extreme demands.
+    \StopItem
+    \StartItem
+        It's user demand that is the driving force behind most new features. Users typically
+        use \CONTEXT\ in a different way than we do.
+    \StopItem
+    \StartItem
+        And \unknown\ some things can probably only be done with \TEX, especially in automated
+        workflows.
+    \StopItem
+\StopItems
+
+\StartItems{Suggestions for designers}
+    \StartItem
+        Talk to those implementing the design, let them show you what can be done. Stick to
+        general designs and don't go into much detail. It's the look and feel that matters.
+    \StopItem
+    \StartItem
+        Think in systematic solutions. Lack of freedom in interactive placement of graphics can
+        be compensated by other variations.
+    \StopItem
+    \StartItem
+        Think outside the box. Use the fact that the system is programmable and can adapt. And it
+        probably goes beyond what you can think of.
+    \StopItem
+    \StartItem
+        Try to make a design extensible. There will always be more structure. Some components

+
+\StartItems{How you code your documents}
+    \StartItem
+        Coding in \TEX\ is quite natural and given a proper macro set
+        the overhead is not that large.
+    \StopItem
+    \StartItem
+        Coding in \XML\ makes sense when you have to manipulate or reuse
+        your data and when \TEX\ is just the renderer.
+    \StopItem
+    \StartItem
+        For non|-|artistic graphics \METAPOST\ provides a convenient input
+        language. It also plays well with \TEX.
+    \StopItem
+    \StartItem
+        Some problems can more conveniently be solved in a procedural programming
+        language and \LUA\ perfectly fits in there.
+    \StopItem
+\StopItems
+
+\StartItems{How the codebase evolves}
+    \StartItem
+        Of course we started with only \TEX\ code. Functionality has been nicely
+        split in modules
+    \StopItem
+    \StartItem
+        Front- and backend code has always been separated.
+    \StopItem
+    \StartItem
+        The user interface is quite consistent which provides backward compatibility
+        as well extensibility.
+    \StopItem
+    \StartItem
+        For quite some time \METAPOST\ support has been tightly integrated, including
+        a  two way communication between these subsystems.
+    \StopItem
+    \StartItem
+        When we decided on \LUA\ as language it didn't take long before large chunks of
+        \CONTEXT\ were rewritten using it.
+    \StopItem
+\StopItems
+
+\StartItems{How the codebase evolves}
+    \StartItem
+        Most font handling takes place in \LUA\ and as usual with \TEX\ we can do more
+        than fonts provide.
+    \StopItem
+    \StartItem
+        Other subsystems, like languages, input encoding, file io and xml also were among
+        the first to be supported by \LUA.
+    \StopItem
+    \StartItem
+        Lots of information is now carried around, especially related to structure. This will
+        permit users more freedom.
+    \StopItem
+    \StartItem
+        Notes, descriptions and enumerations also rely on \LUA.
+    \StopItem
+    \StartItem
+        Graphics (including \METAPOST) is all dealt with in \LUA. Float management is currently
+        on the agenda.
+    \StopItem
+    \StartItem
+        The backend code is completely rewritten in \LUA. We've disabled the low level primitives
+        so that third party modules can not spoil the game (this was already the case in \MKII).
+    \StopItem
+    \StartItem
+        Eventually most management tasks will move from \TEX\ to \LUA, but we keep in pace with
+        \LUATEX\ development and don't push things to the limit.
+    \StopItem
+\StopItems
+
+\StartItems{where we will end up}
+    \StartItem
+        Eventually we will have a more layered macro package so that one can make specialized
+        versions.
+    \StopItem
+    \StartItem
+        In addition to the regular \TEX\ interface there will be a \LUA\ interface. We already have
+        one such interface but there will be more.
+    \StopItem
+    \StartItem
+        It will be possible to avoid \TEX\ code completely which makes sense in predictable
+        workflows where no artistic intervening is needed.
+    \StopItem
+    \StartItem
+        Core \TEX\ functionality will also be available as (often less efficient) \LUA\ variant
+        so that we can extend it. We already provide hooks into the callback subsystem.
+    \StopItem
+    \StartItem
+        We can already all of this intermixed so the user has complete freedom of choice.

+
+    \startitemize
+        \startitem
+            features like additional character kerning don't belong in the font
+            handler as they are (to some extent) macro package dependant
+        \stopitem
+        \startitem
+            the same is true for italic correction (often input related and
+            therefore a macro package specific issue)
+        \stopitem
+        \startitem
+            setting up protrusion and expansion is again somewhat macro package
+            dependent
+        \stopitem
+        \startitem
+            \ConTeXt\ has many extra font related mechanisms and features

+        \stopitem
+        \blank
+        \startitem
+            this has to work well with the core subsystems: languages especially
+            hyphenators, specific script demands, typesetting (all kind), builders
+            (paragraph, page), etc.
+        \stopitem
+        \startitem
+            a complication is that we do this more and more in \Lua, but still need to

+        \startitem

+\item Only a small portion has (or needs) design. \FlushStep
+\item To what extent appreciation matters is hard to measure. \FlushStep

+\Topic{What is an ebook}
+
+\StartSteps
+\startitemize
+\item Nicest is it being a \PDF\ (some design). \FlushStep
+\item Easiest is it being an \XHTML\ file (with some \CSS). \FlushStep
+\item Pointless it is being a frozen app. \FlushStep
+\item We can already provide a \PDF\ for paper and screen for quite a while. \FlushStep
+\item We can consider providing an \XHTML\ alongside as reflowable variant. \FlushStep
+\item Who knows what we can provide in the future. \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{The starting point}
+
+\StartSteps
+\startitemize
+\item No output is better than the input. \FlushStep
+\item Fixing bad coding is a waste of energy. \FlushStep
+\item Not that many publishers want to invest in coding. \FlushStep
+\item Not that many tools enforce structure. \FlushStep
+\item The real good devices still have to come but we can be ready for it. \FlushStep
+\item The intelligence has to be in the macro package, not in the engine. \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Implementation}
+
+\StartSteps
+\startitemize
+\item Some users have to produce tagged pdf (to satisfy validators). \FlushStep
+\item It helps that many commands in \CONTEXT\ are built upon a relatively small generic set. \FlushStep
+\item So, given some basic structure, supporting tags is easy. \FlushStep
+\item It integrates in the core. \FlushStep
+\item And as a side effect an export was equally easy to support. \FlushStep
+\item The overhead is not that large (upto 10\%). \FlushStep
+\item Instead of going for freaky solutions (no need for challenges) we assume proper structure. \FlushStep
+\item It's not to hard to extend the current features. \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Consequence for users}
+
+\StartSteps
+\startitemize
+\item Use \type{\startchapter} cum suis, but that was already the \MKIV\ fashion. \FlushStep
+\item Preferable use \type{\startitem} instead of \type {\item}. \FlushStep
+\item Playing safe means tagging paragraphs with \type {\startparagraph}. \FlushStep
+\item Use style environments instead of font switches. \FlushStep
+\item Just use whatever structural markup that \CONTEXT\ already provides for ages. \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{An example}
+
+\StartSteps
+\startitemize
+\item A normal input with \TEX\ commands (cld-mkiv.tex) \FlushStep
+\item Regular (tagged) output (cld-mkiv.pdf) \FlushStep
+\item Structured output (cld-mkiv.xml) \FlushStep
+\item Reflowable output (cld-mkiv-export.xhtml) \FlushStep

+\Topic{Some developments}
+
+\StartSteps
+\startitemize
+\startitem \MATHML\ started as an interchange format on the one hand (content) \stopitem \FlushStep
+\startitem but also provides a rendering variant (presentation) \stopitem \FlushStep
+\startitem and in the meantime has been merged with what is called open math \stopitem \FlushStep
+\startitem we now have \MATHML\ 3 and \CONTEXT\ has been updated a while ago to support this \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Some history}
+
+\StartSteps
+\startitemize
+\startitem we supported \MATHML\ right from the start \stopitem \FlushStep
+\startitem in \MKII\ quite some data juggling takes place because we need to do some analysis \stopitem \FlushStep
+\startitem the \MKII\ code has been upgraded a few times but is now frozen \stopitem \FlushStep
+\startitem in \MKIV\ we have rewritten all code using the first version of the new \XML\ parser \stopitem \FlushStep
+\startitem it currently is a mixture of \LUA, \TEX\ and \METAPOST \stopitem \FlushStep
+\startitem there will probably be a partial rewrite some day in the future \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{\UNICODE}
+
+\StartSteps
+\startitemize
+\startitem in the meantime \UNICODE\ has been extended with math  \stopitem \FlushStep
+\startitem in the past in \MATHML\ special characters and symbols were accessed by entity \stopitem \FlushStep
+\startitem but now we can exclusively use \UNICODE\ characters and forget about the entities \stopitem \FlushStep
+\startitem no matter what, we do need to do some analysis on the content of (presentation) elements \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Rendering}
+
+\StartSteps
+\startitemize
+\startitem we still provide rendering options as there might be (cultural) differences \stopitem \FlushStep

+\startitem we already use a database or definitions \stopitem \FlushStep
+\startitem we won't go the (somewhat extreme) route of more commands \stopitem \FlushStep
+\startitem we're working on a subsystem for field driven rendering \stopitem \FlushStep
+\startitem bidirectional math already works but will be integrated in the layout model \stopitem \FlushStep
+\startitem cultural specific solutions are possible (we already provide language specific functions) \stopitem \FlushStep
+\startitem more information is carried around (for rendering as well as export), for instance functions \stopitem \FlushStep

+\StartSteps
+\startitemize
+\startitem we started with simple usage (logos) and \POSTSCRIPT\ output \stopitem \FlushStep
+\startitem then we moved on to conversion to \PDF\ using \TEX\ macro solution \stopitem \FlushStep
+\startitem this has the advantage that fonts are handled by \TEX \stopitem \FlushStep
+\startitem for a long time this was a generic solution (later became the \MKII\ variant) \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem we added some extensions (transparency, cmyk, etc) and \METAFUN\ showed up \stopitem \FlushStep
+\startitem that extension mechanism uses special colors as signals \stopitem \FlushStep
+\startitem we always collected btex ... etex in order to speed up processing \stopitem \FlushStep
+\startitem in addition we added textext and similar features \stopitem \FlushStep
+\startitem communication between \METAFUN\ and \CONTEXT\ became more advanced over time \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem when \LUATEX\ showed up a substitution based lua converter was written \stopitem \FlushStep
+\startitem later when \LPEG\ came around an experimental lpeg converter showed up \stopitem \FlushStep
+\startitem some changes were made to textext processing and run management \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem the arrival of mplib had rather big consequences \stopitem \FlushStep
+\startitem integration of \METAFUN\ became less of a runtime burden \stopitem \FlushStep
+\startitem a more definitive lpeg converter was written \stopitem \FlushStep
+\startitem text handling was kept internal (but still needs two passes) \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem some extensions were changed to use the new pre/postscripts functionality \stopitem \FlushStep
+\startitem the lpeg converter was adapted accordingly \stopitem \FlushStep
+\startitem multiple (independent) \METAPOST\ instances were now supported \stopitem \FlushStep
+\startitem the chemical code was overhauled and moved to the core \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem by now all extensions use pre/postscripts \stopitem \FlushStep
+\startitem this made it easier to add more extend functionality \stopitem \FlushStep
+\startitem again the lpeg converter was adapted (simplified) \stopitem \FlushStep
+\startitem it became possible to do some color trickery with text \stopitem \FlushStep
+\startitem but (till now) color spaces are more complex (mp has a mixed model) \stopitem \FlushStep
+\startitem so we might move towards a slightly different approach \stopitem \FlushStep
+\startitem a couple of helpers were added for Mojca (some more will follow) \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem we're now splitting the code in \MPII\ and \MPIV\ code bases \stopitem \FlushStep
+\startitem from now on the focus will be on \MPIV \stopitem \FlushStep
+\startitem the (rather old) \METAFUN\ code will be cleaned up \stopitem \FlushStep
+\startitem where possible namespaces will be added \stopitem \FlushStep
+\startitem as \METAFUN\ us loaded runtime we see an impact on startup time (quite some files) \stopitem \FlushStep
+\startitem so maybe we will use a packed and/or zipped pseudo format file for faster loading \stopitem \FlushStep
+\stopitemize
+\StopSteps
+
+\Topic{Development Stage}
+
+\StartSteps
+\startitemize
+\startitem an overhaul of the flowchart code is on the agenda \stopitem \FlushStep
+\startitem we also want to finish (and cleanup) the chemical related code \stopitem \FlushStep
+\startitem simple data/graphics helpers will be provided (graph replacement) \stopitem \FlushStep
+\startitem and of course we keep moving on (who knows what \METAPOST\ 2 will bring us) \stopitem \FlushStep
+\startitem some examples: tests/mkiv/metapost/plugins-* \stopitem \FlushStep

+        \startitem Some 15 years ago I wanted some more feedback. \stopitem \FlushStep
+        \startitem So I figured out a way to visualize boxes, kerns, glue, etc. \stopitem \FlushStep
+        \startitem Some aspects were tricky, like stretch and shrink (no \ETEX\ yet), fillers, leaders, etc. \stopitem \FlushStep
+        \startitem I gave some presentations and it was nice to see the puzzled faces. \stopitem \FlushStep
+        \startitem As unboxing does not work, it is somewhat interfering. \stopitem \FlushStep

+        \startitem Some make no sense in \MKIV, so they're gone, but new ones show up. \stopitem \FlushStep

+
+        \startitem When cleaning up the code I had to decide to keep it or redo it as it could be done \MKIV-ish. \stopitem \FlushStep
+        \startitem But as we already had some \LUA\ based extras it made sense to redo it. \stopitem \FlushStep

+        \startitem We use rules (and leaders) to visualize properties. \stopitem \FlushStep

+        \startitem Control over what gets shown by using layers. \stopitem \FlushStep
+        \startitem As usual most time went into visualization choices and optimzation. \stopitem \FlushStep
+        \startitem Some visualizers interfered with (hardcoded) expectations in the backend. \stopitem \FlushStep
+        \startitem When I decided to use layers I had to adapt some oter code (mostly out of efficiency). \stopitem \FlushStep

+\StartSteps \starttopic [title={Alphabets}]
+
+    \startitem the shape (style) of a character determines its meaning \FlushStep \stopitem
+    \startitem but in most cases an type {a} is entered as \ASCII\ character \FlushStep \stopitem
+    \startitem and tagged with some rendering directive, often indicating a font style \FlushStep \stopitem
+    \startitem in traditional \TEX\ we have alphabets in different fonts, so we're talking switches \FlushStep \stopitem
+    \startitem in \UNICODE\ and \OPENTYPE\ we have alphabets with standardized code points (but gaps too) \FlushStep \stopitem
+    \startitem this has big advantages for communicating, transferring data etc \FlushStep \stopitem
+    \startitem but a math engine still has to deal with \ASCII\ input as well \FlushStep \stopitem
+    \startitem multiple axis: types, alphabets, styles, variants, shapes, modifiers \FlushStep \stopitem
+
+    \vfilll \conclusion{We're off better but the gaps are an anomality.} \FlushStep

+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Heavy bold}]
+
+    \startitem for titles and captions we might need bolder math \FlushStep \stopitem
+    \startitem bold symbols in math have special meaning \FlushStep \stopitem
+    \startitem so when going full bold they should become heavy \FlushStep \stopitem
+    \startitem heavy math involves boldening everything, including extensibles \FlushStep \stopitem
+    \startitem there are currently no fonts that have such complete heavy companions \FlushStep \stopitem
+
+    \vfilll \conclusion{We need proper bold fonts, but they need to be relatively complete.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Radicals}]
+
+    \startitem this always has been (and still is) a combination of vertical extensibles and horizontal rules \FlushStep \stopitem
+    \startitem it is the only two dimensional extensible so always a bit of an exception \FlushStep \stopitem
+    \startitem in the wide engines we now have more direct support primitive for that (no macro needed) \FlushStep \stopitem
+    \startitem in practice (at least in \MKIV) we still use macros because we want control \FlushStep \stopitem

+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Primes}]
+
+    \startitem this is a special case as we (sort of) have upto two superscripts  \FlushStep \stopitem
+    \startitem and also need to handle an optional subscript of the base symbol \FlushStep \stopitem
+    \startitem and in order to be visually okay, we need to collect multiple primes \FlushStep \stopitem
+    \startitem some fonts have primes raised, some have them flying high \FlushStep \stopitem
+    \startitem maybe at some point the upcoming math pre- and postscripts will help \FlushStep \stopitem

+
+\StartSteps \starttopic [title={Accents}]
+
+    \startitem they can go on top or below one or more characters (also in combination) \FlushStep \stopitem
+    \startitem accents have some hard codes positional properties \FlushStep \stopitem
+    \startitem the wide engines have more direct support for this \FlushStep \stopitem
+    \startitem fonts provide a limited set of sizes, such accents cannot extend (by design) \FlushStep \stopitem
+
+    \vfilll \conclusion{Engine support for accents is better now but maybe fonts need to have more sizes.} \FlushStep

+\stoptopic \StopSteps

+\StartSteps \starttopic [title={Stackers}]
+
+    \startitem arrows (and other horizontal extensibles) traditionally were made from snippets \FlushStep \stopitem
+    \startitem we need them also for chemistry, in rather flexible ways \FlushStep \stopitem
+    \startitem in upcoming math fonts they are become real extensibles \FlushStep \stopitem
+    \startitem but then we still need to deal with existing fonts that lack them (one font in the end) \FlushStep \stopitem
+    \startitem there will be native support for so called character leaders \FlushStep \stopitem
+
+    \vfilll \conclusion{Stackers are more easily implemented although fonts pose some challenges.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Fences}]
+
+    \startitem these go left and right (or in the middle) of things \FlushStep \stopitem
+    \startitem there need to be a matching pair else we get an error \FlushStep \stopitem
+    \startitem they have to adapt their size to what they wrap \FlushStep \stopitem
+    \startitem \TEX ies can take care of that in their input \FlushStep \stopitem
+    \startitem but in for instance \MATHML\ checking all this is a bit of a pain \FlushStep \stopitem
+    \startitem this is still the domain of macros \FlushStep \stopitem
+    \startitem but we could make the engines a bit more tolerant (hard to do) \FlushStep \stopitem

+    \vfilll \conclusion{Matching fences will always be a bit of a problem.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Directions}]
+
+    \startitem bidirectional math is mostly a matter of the availability of fonts \FlushStep \stopitem
+    \startitem there need to be some agreement (at the macro package level) of control \FlushStep \stopitem
+    \startitem it's (for me) a visually interesting challenge \FlushStep \stopitem
+    \startitem there are some \TEX ies working on these matters (quite some research is done already) \FlushStep \stopitem

+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Structure}]
+
+    \startitem demand for tagging also means that we need to carry a bit more info around \FlushStep \stopitem
+    \startitem this puts a little more burden on the user \FlushStep \stopitem
+    \startitem in the end it largely is a macro package issue \FlushStep \stopitem
+    \startitem better tagging of input can also help rendering \FlushStep \stopitem
+    \startitem detailed control at the \TEX\ level makes that users can spoil the game \FlushStep \stopitem

+\StartSteps \starttopic [title={Italic correction}]
+
+    \startitem in traditional \TEX\ fonts this was used for spacing as well as special purposed \FlushStep \stopitem
+    \startitem across fonts there was never much correction \FlushStep \stopitem
+    \startitem \OPENTYPE\ doesn't have this concept \FlushStep \stopitem
+    \startitem \OPENTYPE\ math has some of if but also more powerful kerning \FlushStep \stopitem
+    \startitem generally speaking: we can ignore italic corrections \FlushStep \stopitem
+
+    \vfilll \conclusion{We need to accept that old concepts die and new onces show up.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Big}]
+
+    \startitem normally extensible fences are chosen automatically \FlushStep \stopitem
+    \startitem but macro packages provide tricks to choose a size \FlushStep \stopitem
+    \startitem extensible steps are unpredictable but still several mechanisms can be provided \FlushStep \stopitem
+
+    \vfilll \conclusion{Users will always want control and no engine can provide that but macros can.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Macros}]
+
+    \startitem some special symbols were constructed by macros (and using special font properties) \FlushStep \stopitem
+    \startitem these are mostly gone (the diagonal dots) \FlushStep \stopitem
+    \startitem if it is ever needed again, we should extend the fonts \FlushStep \stopitem
+
+    \vfilll \conclusion{Thanks to new font technologies and wide engines need less dirty tricks.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Unscripting}]
+
+    \startitem you can bet on those funny \UNICODE\ super and subscripts showing up in input \FlushStep \stopitem
+    \startitem it's a somewhat limited and unuseable lot for math (a modifier would have made more sense) \FlushStep \stopitem
+    \startitem it's one of these legacies that we need to deal with \FlushStep \stopitem
+    \startitem so the macro package needs to intercept them and map them onto proper math \FlushStep \stopitem
+
+    \vfilll \conclusion{We always need to deal with weird input, if only because standards lack.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Combining fonts}]
+
+    \startitem we can expect math fonts to be rather complete and if not, one should choose another one \FlushStep \stopitem
+    \startitem but sometimes (for simple math) you want to swap in alphabets and digits that match the text font \FlushStep \stopitem
+    \startitem given that we talk of ranges this is easy to support at the macro package level \FlushStep \stopitem
+
+    \vfilll \conclusion{Although fonts are more complete, occasional combinations should remain possible.} \FlushStep
+
+\stoptopic \StopSteps
+
+\StartSteps \starttopic [title={Tracing}]
+
+    \startitem there are lots of symbols involved \FlushStep \stopitem
+    \startitem and we have those extensibles too \FlushStep \stopitem
+    \startitem the larger the fonts get the more checking we need to do \FlushStep \stopitem
+    \startitem so macro packages need to provide some tracing options (or tables in print) \FlushStep \stopitem

+
+\startstandardmakeup
+
+After ten years of stepwise development and experimenting we release version 1.00
+of \LuaTeX\ during the 10\high{th} \ConTeXt\ meeting in the Netherlands, September
+2016.
+
+The interface is now rather stable and will not change significantly which means
+that one can write stable packages.
+
+So, it's time for a bit reflection as well as time to tell what we will be doing
+next.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+Around 2005, after we talked a bit about it, Hartmut added the \Lua\ scripting
+language to \pdfTeX\ as an experiment.
+
+This add|-|on was inspired by the \Lua\ extension to the Scite editor that I
+(still) use.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+One could query counter registers and box dimensions and print strings to the
+\TeX\ input buffer.
+
+The Oriental \TeX\ project then made it possible to go forward and come up with a
+complete interface.
+
+For this, Taco converted the code base from Pascal to C, an impressive effort.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+We spent more than a year intensively discussing, testing and implementing
+the interface between \TeX\ and \Lua.
+
+In successive years we polished things and extended bits and pieces.
+
+The last few years we cleaned up, filled in gaps and reached the point where we
+were more of less satisfied.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+The core is still traditional \TeX, but extended with \pdfTeX\ protrusion and
+expansion (reworked) and directional features from Aleph (cleaned up).
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+The font subsystem accept now wide fonts.
+
+The hyphenation machinery can use runtime loaded (and extended) patterns.
+
+Hyphenation, ligaturing, kerning are separated.
+
+Most steps in processing node lists can be intercepted using callbacks.
+
+The math machinery has opentype math code paths.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+All in- and output can be controlled and intercepted.
+
+The backend code has been separated better.
+
+You can write (simple) parsers.
+
+Nodes can be accessed and manipulated.
+
+Images and reuseable boxes are now native.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+The project is driven by \ConTeXt\ users and \ConTeXt\ development.
+
+Right from the start \ConTeXt\ supported \LuaTeX.
+
+This means that most mechanisms have been tested in production.
+
+Raw performance is less than 8 bit \pdfTeX\ but in practice and on modern
+machines \LuaTeX\ behaves well.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+We will continue development, but functionality will stay stable within versions.
+Of course bugs will be fixed.
+
+The code will be further streamlined and documented. We deliberately postponed some
+cleanup till after version 1.00.
+
+Of course the manual will be improved over time.

+% ideas
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (1)}
+
+    So far we managed to avoid extensions beyond those needed as part of the opening
+    up.
+
+    We stick close to Don Knuths concepts so that existing documentation still
+    conceptualy applies. We keep our promise of not adding to the core.
+
+    We might open up (make configureable) some of the still hard coded properties.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (2)}
+
+    Some node lists can use a bit of (non critical) cleanup, for instance passive
+    nodes, local par nodes, and other left|-|overs. Maybe we should add missing
+    left|/|right skips.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (3)}
+
+    We can optimize some callback resolution (more direct) so that we can gain a little
+    performance.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (4)}
+
+    Inheritance of attributes needs checking and maybe we need to permits some more
+    explicit settings.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (5)}
+
+    Bring some more code to the api file. Use the global PDF and \Lua\ states
+    consistently. Some macros can probably go away.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (6)}
+
+    Minimize return values of \Lua\ functions; only return nil when we expect
+    multiple calls in in one line.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (7)}
+
+    Figure out a way to deal with literals in virtual characters (relates to font
+    switching in the result).
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (8)}
+
+    Maybe reorganize some code so that documentation is easier. See if we can stick
+    close to what Don Knuth documents.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (9)}
+
+    Cleanup and isolate the backend a bit more. Maybe add a bit more options to
+    delegate to \Lua. Get rid of some historic PDF artifacts.
+
+\stopstandardmakeup
+
+\startstandardmakeup
+
+    \midaligned{Some ideas (10)}
+
+    It is tempting to think of a (lean and mean) \LuaTeX\ variant for \ConTeXt.
+
+    We will not touch stable unless it concerns bug fixes, but we will expose
+    \ConTeXt\ users to the experimental branch (as we do now).
+
+    So \unknown\ be prepared.

+\subject{Presentations}
+
+For demonstration purposes we ship some presentations. Some of these are called
+up when a style is processed (in demo mode). The look and feel evolves with
+\ConTeXt\ and often a style uses some trickery (\TeX, \ConTeXt, \MetaPost, \Lua\
+etc.) I was playing with at that moment. The older styles therefore use more PDF
+trickery than the later ones (especially because in the end the viewers were less
+stable than we hoped).
+
+Of the hundreds of presentations made so far only a subset can be found here. You
+can find some more on the web (conference websites). Many presentations are
+outdated but might have some historic value or show some tricks. The real old
+ones are not here anyway. Some presentations build upon a previous one although I
+try to avoid duplicate talks. Of course status reports can be somewhat redundant
+but keep in mind that meetings are also for developers.
+
+\ConTeXt, \LuaTeX and \MetaPost\ related presentations happened at meetings of \TeX\
+user groups like TUG, NTG, Bacho\TeX, Dante, CSTUG, UKTUG, GUTENBERG, but also at
+other occasions but not all make sense to collect here, if only because when they
+were close in time some were similar. Also, I just deleted some sources when I
+found them irrelevant for reuse. You can always report a missing one in which
+case I'll see if I can find back the source. If you really want some MkII style
+in MkIV too, let me know.

+The (binary) \type {tfm} file is not human readable but can be turned into a
+verbose property list which is not that hard to understand.

+Here is an excerpt from the data file. It starts with some general properties of
+the font. The \type {O} means that the value is in octal while the \type {R} is a
+real. Keep in mind that \TEX\ has no datatype \quote {real} so internally it is
+just integers representing scaled points.

+Kerns and ligatures are packed into a table that is basically a sequence of
+labelled entries. Here we see the entry for the character \type {f} which has
+three ligatures: \type {ff}, \type {fi} and \type {fl}. Because ligatures can be

+
+The character information is also in the \type {tfm} companion and that is what
+\TEX\ uses. The virtual information kicks in when the backend is creating the
+page stream and embedding the fonts.
+
+\stopsection
+
+\startsection[title=The \type {map} file,reference=fontdata:map]
+
+In a map file each line maps a font name onto a file that contains the font
+shapes in bitmap or outline format. For instance in the file \type
+{lm-texnansi.map} we find the line:
+
+\startnarrowtyping
+texnansi-lmr10 LMRoman10-Regular "enclmtexnansi ReEncodeFont" <lm-texnansi.enc <lmr10.pfb
+\stopnarrowtyping
+
+The backend will fetch the glyph data from \type {lmf10.pfb} and use the given
+encoding file to resolve indices to glyph names. A \type {pfb} file can contain
+more than 256 entries so names are used to access the data. The string between
+quotes is used for the encoding vector in the resulting file.
+
+The second entry in the line is the font name that will be used. This name is
+also used to control subset behaviour. Multiple references to this name will be
+collapsed into one inclusion when possible, thereby making the file as small as
+possible. You better make sure that the names are unique for a specific font.
+
+In addition to this, there can be directives for extending the font (horizontal
+stretch) and transforming it into a slanted variant. Both are to be used with
+care.
+
+In \MKIV\ map files are only used for virtual math fonts and just as in \MKII\ we
+load such files selectively. Users don't have to worry about this.
+
+\stopsection
+
+\startsection[title=The \type {enc} file,reference=fontdata:enc]
+
+For historic reasons, an encoding file is a blob of \POSTSCRIPT, probably because
+it can be copied into the final output directly. Given that \TEX\ got extended
+anyway, you can wonder why this information never ended up in an extended \type
+{tfm} or \type {vf} file. It had definitely made the traditional process much
+more robust.

+Watch the comments! Because \TEX\ needs a couple of so called fontdimens to be
+set, the comments list the appropriate values. When a \type {tfm} file is
+generated from an \type {afm} file, these values have to be used.
+
+Each character (or glyph) gets an entry. When we run out of indices i.e.\ pass
+the 255 boundary (we start at 0) the index becomes \type {-1}. Only the width is
+specified. The height and depth have to be derived from the bounding box for
+which the specification starts with key \type {B}.

+
+Watch how this font defines a space character and keep in mind that these fonts
+date from the time that there was only one kind of space. The \type {L} entry
+specifies a ligature.
+
+The names of glyphs are standardized, and even the \type {f_k} is conforming to
+standards. This standardization makes it possible to go back from glyphs to characters
+when copying text from a typeset document.
+
+The kern table is pretty large here and for a reason. First of all the file
+defines 821 glyphs so the average amount of kerns per glyph is not that large.
+But take a look at the \type {A}. Because the \type {Aacute} has the same shape
+it kerns in a similar way. This means that ideally all combined characters end up
+with the same value as their base glyph. However, in our case a bit more
+selective approach is taken. The \type {Adieresis} has a different set of kerns,
+probably to save space. It is for this reason that \OPENTYPE\ fonts have a model
+of kern classes so that similar shapes can be treated as one when setting kerns.
+You see a similar issue with ligatures, where often the right part of the shape
+kerns the same as the (stand alone) first part of the shape does.

+In the \LUATEX\ manual you can find an overview of the raw \OTF\ format as

+to create a more compact and efficient table instead. The current release of
+\CONTEXT\ uses its own loader written in \LUA, but the fundamentals have not
+changed much. The tables are cached and can be read in at high speed. The

+\startsection[title=Introduction]
+
+One of the benefits of using \TEX\ is that you can add your own features and try
+to optimize the look and feel. Of course this can also go wrong and output can
+look pretty awful when you don't know what you're doing, but on the average it
+works out well. In many aspects the move to an \UNICODE\ data path and \OPENTYPE\
+fonts is a good one and solves a lot of problems with traditional \TEX\ engines
+and helps us to avoid complex and ugly hacks. But, if you look into the source
+code of \CONTEXT\ you will notice that there's still quite some complex coding
+needed. This is because we want to control mechanisms, even if it's only for
+dealing with some border cases. It's also the reason why \LUATEX\ is what it is:
+an extensible engine, building on tradition.
+
+As always with \TEX, fonts are an area where many tuning happens and this is also
+true in \CONTEXT. In this chapter some of the extensions will be discussed. Some
+extensions run on top of the (rather generic) feature mechanism and some are
+using dedicated code.
+

+
+\startsection[title=Italics]
+
+Although \OPENTYPE\ fonts are more rich in features than traditional \TEX\ and
+\TYPEONE\ fonts, one important feature is missing: italic correction. This might
+sound strange but you need to keep in mind that in practice it's a feature that
+needs to be applied manually.
+
+\starttyping
+test {\it test\/} test
+\stoptyping
+
+It is possible to automate this mechanism and this is what the \type {\em} command
+does in \MKII:
+
+\starttyping
+test {\em test} test
+\stoptyping
+
+This command knows that it switches to italic (or slanted) and when used nested it
+knows to switch back. It also knows if a bold italic or slanted font is used. Therefore
+it can add italic correction between an italic and upright shape.
+
+An italic correction is bound to a glyph and bound to a font. In \in {figure}
+[latinmodern-italic] we see how an italic shape extends out of the bounding box.
+This is not the case in Dejavu: watch \in {figure} [dejavu-italic].

+Because it is to be used with care you need to enable this feature per font, You

+
+This only signals the font constructor that additional italic information has
+to be added to the font metrics. As we already mentioned, the application of
+correction is driven by the \type {\/} primitive and that one consults the
+font metrics. Because the correction is not part of the original font
+metrics it is calculated automatically by adding a small value to the
+width. This value is calculated as follows:
+
+\starttyping
+factor * (parameters.uwidth or 40) / 2
+\stoptyping
+
+The \type {uwidth} parameter is sometimes part of the specification but if not, we
+take a reasonable default.  The factor is under user control:
+
+\startbuffer
+\definefontfeature
+  [moreitalic]
+  [default]
+  [itlc=5]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+This is demonstrated in \in {figure} [italic-two]. You will notice that for Latin
+Modern (any) correction makes sense, but for Dejavu it probably makes things look
+worse. This is why italic correction is disabled by default. When enabled there
+are several variants:
+
+\starttabulate[|Bl|l|]
+\NC global \NC always apply correction \NC \NR
+\NC text   \NC only apply correction to text \NC \NR
+\NC always \NC apply correction between text and boxes \NC \NR
+\NC none   \NC forget about correction \NC \NR
+\stoptabulate
+
+We keep track of the state using attributes but that comes at a (small) price in terms
+of extra memory and runtime. The \type {global} option simply assumes that we always
+need to check for correction (of course only for fonts that have this feature enables).
+In the given example we used:

+
+The \type {itlc} feature controls if a font gets italic correction applied. In
+principle this is all that the user needs to do, given that the mechanism is
+enabled. These is an extra feature that controls the implementation:
+
+\starttabulate[|T|T|p|]
+\NC itlc        \NC no    \NC don't apply italic correction (default) \NC \NR
+\NC             \NC yes   \NC apply italic correction \NC \NR
+\NC textitalics \NC no    \NC precalculate italic corrections (permit engine usage) \NC \NR
+\NC             \NC yes   \NC precalculate italic corrections (inhibit engine) \NC \NR
+\NC             \NC delay \NC delay calculation of corrections \NC \NR
+\stoptabulate
+
+When \type {textitalics} is set to \type {yes} or \type {delay} the mechanism
+built into the engine is completely disabled. When set to \type {no} the engine
+can kick in but normally the alternative method takes precedence so that the
+engine sees no reason for further action. You can trace italic corrections with:
+
+\starttyping
+\enabletrackers[typesetters.italics]
+\stoptyping

+
+\start \getbuffer \FontWithBB
+
+There are some features that are rather useless and only make sense when figuring out
+issues. An example of such a feature is the following:
+
+\typebuffer
+
+This feature adds a background to each character in a font. In some fonts a glyph
+has a tight bounding box, while on other fonts some extra space is put on the left
+and right. Keep in mind that this feature blocks colored text.

+\stopsection
+
+\startsection[title=Math italics]
+
+In the traditional \TEX\ fonts the width of a glyph was not the real width because
+one had to add the italic correction to it. The engine then juggles a bit with
+these properties. If you run into fonts that are designed this way, you can do this:
+
+\starttyping
+\definefontfeature[mathextra][italicwidths=yes] % fix latin modern
+\stoptyping
+
+This might make \type {$\left|V\right| = \left|W\right|$} look better for such
+fonts. Of course there can be side effects because these fonts assume a
+traditional engine.
+
+\stopsection
+
+\startsection[title=Slanting]
+
+This features (as well as the one described in the next section) are seldom used
+but provided because they were introduced in \PDFTEX.

+The second manipulation is extending the shapes horizontally:

+  [extend=1.3]
+
+\definefontfeature
+  [abitnarrower]

+
+\typebuffer[define,sample]
+
+The result is:

+
+We can also combine slanting and extending:

+\definefontfeature
+  [abitofboth]
+  [default]
+  [extend=1.3,
+   slant=.1]
+\stopbuffer

+\stopsection
+
+\startsection[title=Fixing] % dimensions
+
+This is a rather special one. First we show a couple of definitions:
+
+\startbuffer
+\definefontfeature
+  [dimensions-a]
+  [default]
+  [dimensions={1,1,1}]
+
+\definefontfeature
+  [dimensions-b]
+  [default]
+  [dimensions={1,2,3}]
+
+\definefontfeature
+  [dimensions-c]
+  [default]
+  [dimensions={1,3,2}]
+
+\definefontfeature
+  [dimensions-d]
+  [default]
+  [dimensions={3,3,3}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+As usual you apply such a feature as follows:
+
+\starttyping
+\definefont[MyFont][Serif*dimensions-a sa 2]
+\stoptyping
+
+Alternatively you can use such a feature on its own:
+
+\starttyping
+\definefontfeature
+  [dimensions-333]
+  [dimensions={3,3,3}]
+\definefont[MyFont][Serif*default,dimensions-333 sa 2]
+\stoptyping
+
+In \in {figure} [dimensions-side-by-side] you see these four definitions in
+action. The leftmost rendering is the default rendering. The three numbers in the
+definitions represent the width (in em), height and depth (in ex).
+

+\stopplacefigure
+
+This feature only makes sense for fonts that need a fixed width, like the
+\CJK\ fonts that are used for asian scripts. Normally those fonts already
+have fixed dimensions, but this feature can be used to fix problematic
+fonts or add some more space. However, for such large fonts this also brings a
+larger memory footprint.
+
+A special case is the following:
+
+\startbuffer
+\definefontfeature
+  [dimensions-e]
+  [dimensions=strut]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This will make the height and depth the same as the current strut height and depth:
+
+\startbuffer

+\ruledhbox{\definedfont[Serif*default,dimensions-e at 12pt]clipped}
+\ruledhbox{\definedfont[Serif*default,dimensions-e at 24pt]clipped}
+\stopbuffer
+
+\typebuffer

+The dimensions are (in this case) limited:

+\startsection[title=Unicoding]
+
+Nowadays we will mostly use fonts that ship with a \UNICODE\ aware encoding. And
+in \CONTEXT, even if we use a \TYPEONE\ font, it gets mapped onto \UNICODE.
+However, there are some exceptions, for instance the Zapf Dingbats in \TYPEONE\
+format. These have a rather obscure private encoding and the glyph names run from
+\type {a1} upto \type {a206} and have no relation to what the glyph represents.
+
+In the case of Dingbats we're somewhat lucky that they ended up in \UNICODE, so
+we can relocate the glyphs to match their rightful place. This is done by means
+of a goodies file. We already discussed this in \in {section} [goodies] so we
+only repeat the usage.
+
+\startbuffer
+\definefontfeature

+\stopbuffer
+
+\typebuffer \getbuffer
+
+I tend to qualify the Dingbat font in \TEX\ distributions as rather unstable
+because of name changes and them either or not being included. Therefore it's best to
+use the hard coded name because that triggers the most visible error message when
+the font is not found.
+
+A font like this can for instance be used with the glyph placement macros as is
+demonstrated below. In the last line we see that a direct \UTF\ input also works
+out well.

+\startsection[title=Protrusion]
+
+Protrusion is a feature that \LUATEX\ inherits from \PDFTEX. It is sometimes
+referred to as hanging punctuation but in our case any character qualifies. Also,
+hanging is not frozen but can be tuned in detail. Currently the engine defines
+protrusion in terms of the emwidth which is unfortunate and likely to change.
+\footnote {In general the low level implementation can be optimized as there are
+better mechanisms in \LUATEX.}
+
+It is sometimes believed that protrusion improves for instance narrower columns,
+but I'm pretty sure that this is not the case. It is true that it is taken into
+account when breaking a paragraph into lines, and that we then have a little bit
+more width available, but at the same time it is an extra constraint: if we
+protrude we have to do it for each line (and the whole main body of text) so it's
+just a different solution space. The main reason for applying this feature is
+{\em not} that the lines look better or that we get better looking narrow lines
+but that the right and left margins look nicer. Personally I don't like half
+protrusion of punctuation and hyphens. Best is to have small values for regular
+characters to improve the visual appearance and use full protrusion for hyphens
+(and maybe punctuation).
+
+\startsubsubject[title=protrusion classes]
+
+In \CONTEXT\ we've always defined protrusion as a percentage of the width of a
+glyph. From \MKII\ we inherit the level of control as well as the ability to
+define vectors. The shared properties are collected in so called classes and the
+character specific properties in vectors. The following classes are predefined:

+
+Vectors are larger but not as large as you might expect. Only a subset of
+characters needs to be defined. This is because in practice only latin scripts
+are candidates and these scripts have glyphs that look a lot like each other. As
+we only operate on the horizontal direction characters like \quote
+{aàáâãäå} look the same from the left and right so we only have to define
+the protrusion for \quote {a}.
+

+\startsection[title=Expansion]
+
+Expansion is also an inheritance of \PDFTEX. \footnote {As with protrusion the
+implementation in the engine is somewhat suboptimal and inefficient and will be
+upgraded to a more \LUATEX-ish way.} This mechanism selectively expands
+characters, normally upto 5\%. One reason for applying it is that we have less
+visually incompatible spacing, especially when we have underfull or cramped
+lines. For each (broken) line the badness is reconsidered with either shrink or
+stretch applied to all characters in that line. So, in the worst case a shrunken
+line is followed by a stretched one and that can be visible when the scaling
+factors are chosen wrong.
+
+As with protrusion, the solution space is larger but so are the constraints. But
+contrary to protrusion here the look and feel of the whole line can be made
+better but at the cost of much more runtime and larger (\PDF) files.
+
+\startsubsubject[title=protrusion classes]
+
+The amount of expansion depends in the shape of the character. Vertical strokes
+are more sensitive for expansion then horizontal ones. So an \quote {o} can
+get a different scaling than an \quote {m}. As with protrusion we have collected
+the properties in classes:
+
+\showexpansionclass
+
+The smaller the step, the more instances of a font we get, the better it
+looks, and the larger the files become. it's best not to use too many stretch
+and shrink steps. A stretch of 2 and shrink of 2 and step of .25 results in
+upto 8~instances plus the regular sized one.

+\startsubsubject[title=Expansion and kerning]
+
+When we expand glyphs we also need to look at the font kerns between them. In the
+original implementation taken from \PDFTEX\ expansion was implemented using pseudo
+fonts (with expanded glyph widths) and expansion of inter|-|character kerns was
+based on font information. In \LUATEX\ we have expansion factors in glyph nodes
+instead which is more efficient and gives a cleaner separation between front- and
+backend as the backend has no need to consult the font.
+
+For the font kerns we set the kern compensation directly and for that we use the
+average expansion factors of the neighbouring fonts so technically we support
+kerns between different fonts). This also has the advantage that kerns injected
+in node mode are treated well, given that they are tagged as font kern.
+
+So what is the effect (and need) of scaling font kerns? Let's look at an example.
+Kerns can be positive but also negative:
+
+\startlinecorrection
+\startcombination
+    {\vbox {
+        \forgetall
+        \hpack to 3cm{\hss\ruledhbox{\maincolor V\kern-1ptA}\hss}
+        \hpack to 3cm{\hss\ruledhbox{\maincolor V\kern 0ptA}\hss}
+    }} {negative}
+    {\vbox {
+        \forgetall
+        \hpack to 3cm{\hss\ruledhbox{\maincolor I\kern.25ptI}\hss}
+        \hpack to 3cm{\hss\ruledhbox{\maincolor I\kern  0ptI}\hss}
+    }} {positive}
+\stopcombination
+\stoplinecorrection
+
+If we use a rediculous amount of stretch we get the following. In the top line we
+scale the kern, in the bottom line we don't.
+
+\startlinecorrection
+\startcombination
+    {\vbox {
+        \definedfont[file:texgyrepagella-regular.otf at 12pt]%
+        \forgetall
+        \hpack to 3cm{\maincolor \hss\strut \scale[xscale=5000]{V}\kern-5pt\scale[xscale=5000]{A}\hss}
+        \hpack to 3cm{\maincolor \hss\strut \scale[xscale=5000]{V}\kern-1pt\scale[xscale=5000]{A}\hss}
+    }} {negative}

+        \hpack to 3cm{\maincolor \hss\strut \scale[xscale=5000]{I}\kern0.25pt\scale[xscale=5000]{I}\hss}
+    }} {positive}
+\stopcombination
+\stoplinecorrection
+
+The reason that we mention this is that when we apply \OPENTYPE\ features,
+positioning not necessarily result in font kerns. For instance ligatures can be
+the result of careful applied kerns and in some scripts kerns are used to connect
+glyphs. This means that we best cannot expand kerns by default. How bad is
+that? By looking at the examples above one would say \quotation {real bad}.
+
+But say that we have about 1pt of font kerns, then a 5\% expansion (which is
+already a lot) amounts to 0.05pt so to \blackrule [width=1pt, height=max,
+depth=max] we add \blackrule [width=.05pt, height=max, depth=max] which is so
+little that it probably goes unnoticed. Even if we use extreme kerns, as between
+VA, in practice the small amount of stretch or shrink added to a font kern goes
+unnoticed.
+
+In \in {figure} [hz:natural] we have overlayed the different strategies. The
+sample and width is chosen such that we see something. On a display you can
+scale up these examples and inspect if there is really something to see,
+but on paper zooming in helps, as in \in {figure} [hz:zoomed]. Even then the
+effect of expanded kerns is invisible. The used definitions are:

+
+Fonts like Latin Modern have lots of glyphs but still lack some. Although the
+composer can add some of the missing, some of those new virtual glyphs probably
+will never look real good. For instance, putting additional accents on top of
+already accented uppercase characters will fail when that character has a rather
+tight (or even clipped) boundingbox in order not to spoil the lineheight. You can
+get some more insight in the process by turning on tracing:
+
+\starttyping
+\enabletrackers[fonts.composing.visualize]
+\stoptyping
+
+One reason why composing can be suboptimal is that it uses the boundingbox of the
+characters that are combined. If you really depend on a specific font and need
+some of the missing characters it makes sense to spend some time on optimizing
+the rendering. This can be done via the goodies mechanism. As an example we've
+added \type {lm-compose-test.lfg} to the distribution. First we show how it
+looks at the \TEX\ end:
+
+\startbuffer

+The positions of the dot accents on top and below the capital B is defined
+in a goodie file:

+  version = "1.00",
+  comment = "Goodies that demonstrate composition.",
+  author = "Hans and Mojca",
+  copyright = "ConTeXt development team",
+  compositions = {
+    ["lmroman12-regular"] = compose,
+  }
+}
+\stoptyping
+
+As this is an experimental feature there are several ways to deal with
+this. For instance:
+
+\starttyping
+local defaultfraction = 10.0
+
+local compose = {
+  dy       = defaultfraction,
+  [0x1E02] = { -- B dot above
+      dy = 150
+  },
+  [0x1E04] = { -- B dot below
+      dy = 150
+  },
+}
+\stoptyping
+
+Here the fraction is relative to the difference between the height of the
+accentee and the accent. A better solution is the following:
+
+\starttyping
+local compose = {
+  [0x1E02] = { -- B dot above
+    anchored = "top",
+  },
+  [0x1E04] = { -- B dot below
+    anchored = "bottom",
+  },
+  [0x0042] = { -- B
+    anchors = {
+      top = {
+        x = 300, y = 700,
+      },
+      bottom = {
+        x = 300, y = -30,
+      },
+    },
+  },
+  [0x0307] = {
+    anchors = {
+      top = {
+        x = -250, y =  550,
+      },
+    },
+  },
+  [0x0323] = {
+    anchors = {
+      bottom = {
+        x = -250, y =  -80,
+      },
+    },
+  },
+}
+\stoptyping
+
+This approach is more or less the same as \OPENTYPE\ anchoring. It takes a bit
+more effort to define these tables but the result is better.

+\startsection[title=Kerning]
+
+Inter|-|character kerning is not supported at the font level and with good
+reason. The fact that something is conceptually possible doesn't mean that we
+should use or support it. Normally proper kerning (or the lack of it) is part
+of a font design and for some scripts different kerning is not even an option.
+
+On the average \TEX\ does a proper job on justification but not all programs
+are that capable. As a consequence designers (at least we ran into it) tend to
+stick to flush left rendering because they don't trust their system to do a
+proper job otherwise. On the other hand they seem to have no problem with
+messing up the inter|-|character spacing and even combine that with excessive
+inter|-|word spacing {\em if} they want to achieve justification (without
+hyphenation). And it can become even worse when extreme glyph expansion (like
+hz) is applied.
+
+Anyhow, it will be clear that consider messing with properties like kerning that
+are part of the font design is to be done careful.
+
+\definecharacterkerning [extremekerning] [factor=.125]
+
+\start \setcharacterkerning[extremekerning]
+
+For running text additional kerning makes no sense. It not only looks
+bad, it also spoils the grayness of a text. When it is applied we need
+to deal with special cases. For instance ligatures make no sense so they
+should be disabled. Additional kerning should relate to already present
+kerning and interword spacing should be adapted accordingly. Embedded
+non|-|characters also need to be treated well.

+\startsection[title=Ligatures]
+
+For some Latin fonts ligature building is quite advanced, take Unifraktur. I have no
+problem admitting that I find fraktur hard to read, but this one actually is sort of
+an exception. It's also a good candidate for a screen presentation where you mainly
+made notes for yourself: no one has to read it, but it looks great, especially if
+you consider it to be drawn by a pen.
+
+Anyway, we will use the following code as example (based on some remarks on the
+fonts website).
+
+\startbuffer[sample]
+sitzen / ſitzen / effe fietsen / ch ck ſt tz ſi fi
+\stopbuffer
+
+\typebuffer[sample]
+
+Some ligatures are implemented in the usual way, using the \type {liga} and \type {dlig}
+features, others kick in thanks to \type {ccmp}. This fact alone is an illustration that
+the low level \OPENTYPE\ ligature feature is not related to ligatures at all but a more
+generic mechanism: you can basically combine multiple shapes into one in all features
+exposed to the user.
+
+We define a bunch of specific feature sets:
+
+\startbuffer
+\definefontfeature
+  [unifraktur-a]
+  [default]
+\definefontfeature
+  [unifraktur-b]
+  [default]
+  [goodies=unifraktur,keepligatures=yes]
+\definefontfeature
+  [unifraktur-c]
+  [default]
+  [ccmp=yes]
+\definefontfeature
+  [unifraktur-d]

+  [ccmp=yes,goodies=unifraktur,keepligatures=yes]
+\definefontfeature

+  [default]
+  [liga=no,rlig=no,clig=no,dlig=no,ccmp=yes,keepligatures=auto]
+\stopbuffer
+
+\getbuffer \typebuffer
+
+and also some fonts:
+
+\startbuffer
+\definefont[TestA][UnifrakturCook*unifraktur-a sa 0.9]
+\definefont[TestB][UnifrakturCook*unifraktur-b sa 0.9]
+\definefont[TestC][UnifrakturCook*unifraktur-c sa 0.9]
+\definefont[TestD][UnifrakturCook*unifraktur-d sa 0.9]
+\definefont[TestE][UnifrakturCook*unifraktur-e sa 0.9]
+\stopbuffer
+
+\getbuffer \typebuffer
+
+We show these five alternatives here:
+
+\starttabulate[|T||]
+\NC liga                        \NC \TestA\getbuffer[sample] \NC \NR
+\NC liga + keepligatures        \NC \TestB\getbuffer[sample] \NC \NR

+\NC liga + ccmp + keepligatures \NC \TestD\getbuffer[sample] \NC \NR
+\NC ccmp + keepligatures        \NC \TestE\getbuffer[sample] \NC \NR
+\stoptabulate
+
+The real fun starts when we want to add extra spacing between characters. Some
+ligatures need to get broken and some kept.
+

+\setupcharacterkerning[letterspacing] [factor=0.5]
+\stopbuffer
+
+\getbuffer \typebuffer
+
+\enabletrackers[typesetters.kerns.ligatures]
+
+Next we will see how ligatures behave depending on how the mechanisms are set
+up. The colors indicate what trickery is used:
+
+\starttabulate[|T||]
+\NC \color[darkred]  {red}   \NC kept by dynamic feature \NC \NR
+\NC \color[darkgreen]{green} \NC kept by static feature  \NC \NR
+\NC \color[darkblue] {blue}  \NC keep by goodie          \NC \NR
+\stoptabulate
+
+First we use \type {\kerncharacters}:
+
+\starttabulate[|T||]
+\NC liga                        \NC \kerncharacters {\TestA\getbuffer[sample]} \NC \NR
+\NC liga + keepligatures        \NC \kerncharacters {\TestB\getbuffer[sample]} \NC \NR
+\NC liga + ccmp                 \NC \kerncharacters {\TestC\getbuffer[sample]} \NC \NR
+\NC liga + ccmp + keepligatures \NC \kerncharacters {\TestD\getbuffer[sample]} \NC \NR
+\NC ccmp + keepligatures        \NC \kerncharacters {\TestE\getbuffer[sample]} \NC \NR
+\stoptabulate
+
+In the next example we use \type {\letterspacing}:
+
+\starttabulate[|T||]
+\NC liga                        \NC \letterspacing {\TestA\getbuffer[sample]} \NC \NR
+\NC liga + keepligatures        \NC \letterspacing {\TestB\getbuffer[sample]} \NC \NR
+\NC liga + ccmp                 \NC \letterspacing {\TestC\getbuffer[sample]} \NC \NR
+\NC liga + ccmp + keepligatures \NC \letterspacing {\TestD\getbuffer[sample]} \NC \NR
+\NC ccmp + keepligatures        \NC \letterspacing {\TestE\getbuffer[sample]} \NC \NR
+\stoptabulate
+
+\disabletrackers[typesetters.kerns.ligatures]
+
+The difference is that the letterspacing variant dynamically adds the predefined
+featureset \type {letterspacing} which is defined in a similar way as \type
+{unifraktur-e}. In the case of this font, this variant is the better one to use.
+In fact, this variant probably works okay with most fonts. However, by not hard
+coding this behaviour we keep control, as one never knows what the demands are.
+When no features are used, information from the (given) goodie file \type
+{unifraktur.lfg} is consulted:
+
+\starttyping
+letterspacing = {
+  -- watch it: zwnj's are used (in the tounicodes too)
+  keptligatures = {
+    ["c_afii301_k.ccmp"] = true, -- ck
+    ["c_afii301_h.ccmp"] = true, -- ch
+    ["t_afii301_z.ccmp"] = true, -- tz
+    ["uniFB05"]          = true, -- ſt
+  },
+}
+\stoptyping
+
+These kick in when we don't disable ligatures by setting features (case~e).
+
+There are two pseudo features that can help us out when a font doesn't provide
+the wanted ligatures but has the right glyphs for building them. The \UNICODE\
+database has some information about how characters can be (de)composed and we can
+use that information to create virtual glyphs:
+
+\starttyping
+\definefontfeature
+  [default] [default]
+  [char-ligatures=yes,mode=node]
+\stoptyping
+
+and:
+
+\starttyping
+\definefontfeature
+  [default] [default]
+  [compat-ligatures=yes,mode=node]
+\stoptyping
+
+This feature was added after some discussion on the \CONTEXT\ mailing list about
+the following use case.
+
+\startbuffer
+\definefontfeature
+  [default-l] [default]
+  [char-ligatures=yes,
+   compat-ligatures=yes,
+   mode=node]
+
+\definefont[LigCd][cambria*default]
+\definefont[LigPd][texgyrepagellaregular*default]
+\definefont[LigCl][cambria*default-l]
+\definefont[LigPl][texgyrepagellaregular*default-l]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+These definitions result in:
+
+\starttabulate[|l|l|l|l|l|]
+\NC                    \NC \type {\LigCd}     \NC \type {\LigPd}     \NC \type {\LigCl}     \NC \type {\LigPl}     \NC \NR

+\stoptabulate

+Of course one can wonder is this is the right approach and if it's not better to
+use a font that provides the needed characters in the first place.
+
+\stopsection
+
+\startsection[title=New features]
+
+\startsubsection[title=Substitution]
+
+It is possible to add new features via \LUA. Here is an example of a single
+substitution:
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "stest",
+        type = "substitution",
+        data = {
+            a = "X",
+            b = "P",
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We show an overview at the end of this section, but here is a simple example
+already. You need to define the feature before defining a font because otherwise
+the font will not know about it.
+
+\startbuffer
+\definefontfeature[stest][stest=yes]
+\definedfont[file:dejavu-serifbold.ttf*default]
+abracadabra: \addff{stest}abracadabra
+\stopbuffer
+
+\typebuffer \start \blank \maincolor \getbuffer \blank \stop
+
+Instead of (more readable) glyph names you can also give \UNICODE\ numbers:
+
+\starttyping
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "stest",
+        type = "substitution",
+        data = {
+            [0x61] = 0x58
+            [0x62] = 0x50
+        }
+    }
+\stopluacode
+\stoptyping
+
+The definition is quite simple: we just map glyph names (or unicodes) onto
+other ones. An alternate is also possible:
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "atest",
+        type = "alternate",
+        data = {
+            a = { "X", "Y" },
+            b = { "P", "Q" },
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Less useful is a multiple substitution. Normally this one is part of a chain of
+replacements.
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "mtest",
+        type = "multiple",
+        data = {
+            a = { "X", "Y" },
+            b = { "P", "Q" },
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+A ligature (or multiple to one) is also possible but normally only makes sense when
+there is indeed a ligature. We use a similar definition for mapping the \TEX\ input
+sequence \type {---} onto an \emdash.
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "ltest",
+        type = "ligature",
+        data = {
+            ['1'] = { "a", "b" },
+            ['2'] = { "d", "a" },
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\stopsubsection
+
+\startsubsection[title=Positioning]
+
+You can define a kern feature too but when doing so you need to use measures in
+font units.
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "ktest",
+        type = "kern",
+        data = {
+            a = { b = -500 },
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Pairwise positioning is more complex and involves two (optional) arrays
+that specify \type {{dx dy wd ht}} for each of the two glyphs. In the next
+example we only displace the second glyph.
+
+\startbuffer
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "ptest",
+        type = "pair",
+        data = {
+            ["a"] = { ["b"] = { false,  { -1000, 1200, 0, 0 } } },
+        }
+    }
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Of course you need to know a bit about the metrics of the glyphs involved so in
+practice this boils down to trial and error.
+
+\stopsubsection
+
+\startsubsection[title=Examples]
+
+We didn't show usage yet. This is because we need to define a feature before we
+define a font. New features will be added to a font when it gets defined.

+\stopluacode
+\stopbuffer

+\typebuffer \getbuffer
+

+table.

+\stopsubsection
+
+\startsubsection[title={Language dependencies}]
+
+When \OPENTYPE\ was not around we only had to deal with ligatures, smallcaps and
+oldstyle and of course kerns. Their number was so small that the term \quote
+{features} was not even used. In practice one just loaded a font that had
+oldstyle or smallcaps or none of that and was done. There were different fonts and
+sold separately.
+
+In \OPENTYPE\ we have more variation and although these fonts can be much more
+advanced the lack of standardization (for instance what gets initialized, or what
+shapes are in the default slots) can lead to messy setups. Some fonts bind
+features to scripts, some don't, which means that:
+
+\starttyping
+\definefontfeature[smallcaps][smcp=yes,script=dflt]
+\definefontfeature[smallcaps][smcp=yes,script=latn]
+\definefontfeature[smallcaps][smcp=yes,script=cyrl]
+\stoptyping
+
+are in fact different and you don't know in advance if you need to specify \type
+{dflt} or \type {latn}. In practice for a feature like smallcaps there is no
+difference between languages, but for ligatures there can be.
+
+When we extend an existing feature we can think of:
+
+\starttyping
+\definefontfeature[smallcaps][default][smcp=yes,script=auto]
+\definefontfeature[smallcaps][default][smcp=yes,script=*]
+\stoptyping
+
+but that can have side effects too (for instance disabling language specific
+features). The easiest way to explore this language dependency is to make
+a feature of our own.
+
+\startbuffer
+\startluacode
+fonts.handlers.otf.addfeature {
+    name     = "simplify",
+    type     = "multiple",
+    prepend  = true,
+    features = {
+        ["*"] = {
+            ["deu"] = true
+        }
+    },
+    data     = {
+        [utf.byte("ä")] = { "a", "e" },
+        [utf.byte("Ä")] = { "A", "E" },
+        [utf.byte("ü")] = { "u", "e" },
+        [utf.byte("Ü")] = { "U", "E" },
+        [utf.byte("ö")] = { "o", "e" },
+        [utf.byte("Ö")] = { "O", "E" },
+        [utf.byte("ß")] = { "s", "z" },
+        [utf.byte("ẞ")] = { "S", "Z" },
+    },
+}
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Here we implement a language specific feature that we use at the \TEX\ end:
+
+\startbuffer
+\definefontfeature
+  [simplify-de]
+  [simplify=yes,
+   language=deu]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+that we can use as:
+
+\startbuffer
+\definedfont[Serif*default,simplify-de]%
+äüöß
+{\de äüöß}
+{\nl äüöß}
+\stopbuffer
+
+\typebuffer
+
+and get: \start \maincolor \inlinebuffer \stop, but as you see, both German and
+Dutch get the same treatment, which might not be what you want, because in Dutch
+the diearesis has a different meaning.
+
+\startbuffer
+\definedfont[Serif*default]%
+                       äüöß
+{\de\addff{simplify-de}äüöß}
+{\nl                   äüöß}
+\stopbuffer
+
+\typebuffer
+
+The above is restricts the usage so now we get: \start \maincolor \inlinebuffer
+\stop, which is more language bound. You don't need much imagination for
+extending this:
+
+\startbuffer
+\definefontfeature
+  [simplify]
+  [simplify=yes,
+   language=deu]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\definedfont[Serif*default]%
+                    äüöß
+{\de\addff{simplify}äüöß}
+{\nl\addff{simplify}äüöß}
+\stopbuffer
+
+So what do we expect with the next?
+
+\typebuffer
+
+We get: \start \maincolor \inlinebuffer \stop, and we see that the language
+setting is not taken into account! This is because the font already has been set
+up with a script and language combination. The solution is to temporary set the
+font related language explicitly:
+
+\definefontfeature
+  [simplify]
+  [simplify=yes]
+
+\startbuffer
+\definedfont[Serif*default]%
+                                  äüöß
+{\de\addfflanguage\addff{simplify}äüöß}
+{\nl\addfflanguage\addff{simplify}äüöß}
+\stopbuffer
+
+\typebuffer
+
+So we can automatically switch to language specific features if we want to:
+\start \maincolor \inlinebuffer \stop.
+
+Let's now move to another level of complexity: support for more than one language
+as in fact this example was made for Dutch in the first place, but the German
+outcome is a bit more visible.

+\stopbuffer
+
+\typebuffer
+
+Because the Dutch is hard to check we use an \type {æ} replacement too and
+commented the similarities with German: \start \maincolor \inlinebuffer \stop.
+But still we're not done, say that we want smallcaps too:
+
+\startbuffer
+\definefontfeature[alwayssmcp][smcp=always]%
+\definedfont[Serif*default,simplify,alwayssmcp]%
+                   äüöß ijæ

+{\nl\addfflanguage äüöß ijæ}
+\stopbuffer
+
+\typebuffer
+
+This comes out as: \start \maincolor \inlinebuffer \stop.
+
+The reason for specifying \type{smcp} as \type {always} is that otherwise we
+get language specific smallcaps while often they are not bound to a language
+but to the defaults. The good news is that we can do this automatically:
+
+\startbuffer
+\setupfonts[language=auto]%
+\definefontfeature[alwayssmcp][smcp=always]%

+In the examples we have seen several ways to define features. One of the
+differences is that you either set a \type {data} field directly, or that you
+specify a dataset. The fields in a dataset entry overload the ones given at the
+top level or when not set the top level value will be taken. There is a bit
+of (downward compatibility) tolerance built in, but best not depend on that.

+You can add virtual characters to fonts. Here we give an example that is derived
+from an example posted on the mailing list. By default, when we hyphenated a word,
+we get this:
+
+\definefont[DemoFont] [Serif*default]
+
+\blank \start \DemoFont \maincolor \hsize 1mm averylongword \par \stop \blank
+
+The default character that is appended at the end and beginning of a line
+can be specified as follows:
+
+\startbuffer
+\setuplanguage
+  [en]
+  [righthyphenchar=45,
+   lefthyphenchar=45]
+\stopbuffer
+
+\typebuffer
+
+So now we get:
+
+\blank \start \getbuffer \DemoFont \maincolor \hsize 1mm averylongword \par \stop \blank
+
+Say that we want a different signal, for instance some rule. Here is how that can
+be done:
+
+\typebuffer[hyphenchars]
+
+\getbuffer[hyphenchars]
+
+Watch the way we use private slots. You can best use a unique glyph name as these
+numbers are shared between fonts. With:

+\startbuffer

+\stoplinecorrection
+
+Most fonts have a space character and you can actually use it and indeed a space
+character will be injected but as it is not glue, the line break algorithm will
+not see it as space.
+
+Al the magic done with space characters other than the native space character
+(decimal 32) are at some point translated into glue.

+The last one is not un \UNICODE\ and the fifths of an emspace is not in \UNICODE\
+either. This emspace (or quad in \TEX\ speak) is a font property. The width of
+the space used by \CONTEXT\ is dreived form this value. In case of a monospace
+fonts, the following logic is applied:
+
+\startitemize
+    \startitem
+        When there is a space character, the width of that character is used.
+    \stopitem
+    \startitem
+        Otherwise, when there is an emdash present, the width if that character
+        is used.
+    \stopitem
+    \startitem
+        Otherwise, when there is an \type {charwidth} property available (the
+        average width), that valua is used.
+    \stopitem
+\stopitemize
+
+When a proportional font is used, we do as follows:
+
+\startitemize
+    \startitem
+        When there is a space character, the width of that character is used.
+    \stopitem
+    \startitem
+        Otherwise, when there is an emdash present, the width of that character
+        divided by two is used.
+    \stopitem
+    \startitem
+        Otherwise, when there is an \type {charwidth} property available (the
+        average width), that value is used.
+    \stopitem
+\stopitemize
+
+In both cases, when no value is set we use the units of the font (often 1000 or
+2048). In \TEX\ a space glue also has stretch and shrink. Here we follow the
+traditional \TEX\ logic:
+
+\startitemize
+    \startitem
+        The stretch is set to half the width of a space but to zero with a mono
+        spaced font.
+    \stopitem
+    \startitem
+        The shrink is set to one third of the width of a space but to zero with a
+        mono spaced font.
+    \stopitem
+\stopitemize
+
+The xheight is set to the values specified by the font and when this is unset the
+height of the character \type {x} will be used but when this character is not in
+the font, we use two fifths of the font's units (normally the same as the
+emwidth). The italic angle is also taken from the font (and is of course zero for
+a not italic font). Most fonts have these properties set so we seldom have to
+fall back to a guess.
+
+\stopsection

+\startsection[title=Ligatures]
+

+  [default]
+  [default]
+  [blockligatures=yes]

+\setupbodyfont[pagella]
+
+...
+\stoptyping
+
+This way it works globally. Of course you can also bind it to a font instance:
+
+\startbuffer
+\blockligatures[fi,fl]
+
+\definefontfeature
+  [default:blockligs]
+  [default]
+  [blockligatures=yes]
+
+\definefont[DemoBlockY][Serif*default:blockligs at 20pt]
+\definefont[DemoBlockN][Serif*default           at 20pt]
+
+Here we have no ligatures: {\DemoBlockY fi ff fl}, while here we get
+them: {\DemoBlockN fi ff fl}. Of course it also depends on the font.
+\stopbuffer
+
+\typebuffer \start \showfontkerns \getbuffer \par \stop
+
+There is one limitation: you need to specify the blocked ligatures before a font
+gets defined and because we share resources it even has to happen before the
+first font gets loaded. So, the \type {\blockligatures} commands go before
+setting up the body font. This is no real problem because it's a hack anyway.

+\startsection[title=Introduction]
+
+If you look into fonts, it is hard not to bump into kerns (spacing between
+characters) and ligatures (combining multiple shapes into one) and apart from
+monospaced fonts most \TYPEONE\ fonts have them. In the \OPENTYPE\ universe we
+call these properties features and in such a font there can be many such
+features.
+
+For those who grew up with \TEX\ or still remember the times of eight bit fonts,
+it is no secret that \TEX\ macro packages did some magic to get most out of a
+font: replacing missing glyphs, fixing metrics, using commands to access shapes
+that had a weird code point, to mention a few. As there is absolutely no
+guarantee that an \OPENTYPE\ font does better, there is a good reason to continue
+messing around with fonts. After all, it's what \TEX\ users seem to like:
+control.
+
+So, when we started writing support for \OPENTYPE\ quite soon a mechanism has
+been created that permits adding our own features to the repertoire that comes
+with a font. Because \OPENTYPE\ features demand a configuration and control
+mechanism, it made sense to generalize that and provide a single interface.
+
+This means that when we talk about font features, we don't limit ourselves to
+those provided by the font, but also those provided by \CONTEXT. As with font
+features, they are enabled per font.
+
+Some of the extra features are sort of generic, others are very font specific and
+their properties are somewhat bound to a font. Such features are defined in a
+font goodie files. Consider these goodies a font extension mechanism.
+
+Some features need information that only the engine can provide. This is why we
+have analyzers. Some are generic, others are bound to scripts. They come in
+action before features are applied. Rather special is applying features in
+combination with paragraph building. This is something very specific to \CONTEXT\
+but it depends on properties of the font. It falls into the category \quote
+{optimizing}.
+
+It is clear that when we talk of features many aspects of a font play a role. In
+this chapter we will discuss all the mentioned aspects. There is quite a bit of
+\LUA\ code shown in this chapter, but don't worry, users will seldom need to
+tweak fonts this way. On the other hand it's good to see what is possible.

+\startsubsection[title=Introduction]
+
+The \OPENTYPE\ specification, which can be found on the \MICROSOFT\ website
+is no easy reading. Some of the concepts are easy to understand, like relative
+positioning (that we call kerning in \TEX) or ligature substitution (as we
+have ligatures in \TEX\ too). It makes no sense to discuss the bitwise composition
+of an \OPENTYPE\ or \TRUETYPE\ file here. First of all, all we get to see is
+a \LUA\ table, and in \CONTEXT\ even that one gets sanitized and optimized
+into a more useable table. However, as the data that comes with a font is
+a good indication of what a font is capable of, we will discuss some of it in
+an appendix. In this section we will discuss the basic principles and categories
+of features.
+
+\stopsubsection
+
+\startsubsection[title=Feature sets]
+
+Because in the next examples we will demonstrate features, we need to know how
+we can tell \CONTEXT\ what features to use. Although you can add explicit
+feature definitions to a font specification, I strongly advice you not to do this
+but use the more abstract mechanism of feature sets. These are defined as follows:
+
+\starttyping
+\definefontfeature
+  [MyFeatureSet]
+  [alpha=yes,
+   beta=no,
+   gamma=123]
+\stoptyping
+
+Such a set is bound to a font with the \type {*} specifier, as in:
+
+\starttyping
+\definefont
+  [MyFontInstance]
+  [MyNiceFont*MyFeatureSet at 12pt]
+\stoptyping
+
+In most cases the already defined \type {default} feature set will suffice. It often
+makes sense to use that one as base for new definitions:
+
+\starttyping
+\definefontfeature
+  [MyFeatureSet]
+  [default]
+  [alpha=yes,
+   beta=no,
+   gamma=123]
+\stoptyping
+
+The second argument can be a list, as in:
+
+\starttyping
+\definefontfeature
+  [MyFeatureSet]
+  [MyFirstSet,MySecondSet]
+  [alpha=yes,
+   beta=no,
+   gamma=123]
+\stoptyping
+
+Of course you need to know what features a font support, and one way to find
+out is:
+
+\starttyping
+mtxrun --script font --list --info --pattern=pagella
+\stoptyping
+
+Don't be too surprised if different fonts show different features and even similar
+features can be implemented differently. Sometimes you really need to know the font,
+but fortunately many fonts come with examples.
+
+There are many features and there values are kept with the font when it gets
+defined. This means that when you change a featureset, it will not affect already
+defined fonts. Because fonts are often defined on demand, you need to be aware of
+the fact that a redefinition of a featureset can have consequences for already
+defined fonts. For instance, a bodyfont switch only sets up the fonts and delays
+defining them.
+
+Although features are a sort of abstractions it can be interesting to see what features
+and values are actually used:
+
+\starttyping
+\usemodule[fonts-features] \showusedfeatures
+\stoptyping
+
+You will notice that we have more features than \OPENTYPE\ fonts can offer. This
+is because in \CONTEXT\ features is a more general concept.
+
+\showusedfeatures
+
+\stopsubsection
+
+\startsubsection[title=Main categories]
+
+There are two (but potentially more) main groups of features: those that deal
+with substitution, and those that lead to positioning. It is not really needed
+to know the gory details, but it helps to know at least a bit about them as
+it can help to track down issues with fonts.
+
+There are several substitutions possible:
+
+\startitemize[packed]
+\startitem a single substitution replaces one glyph by another \stopitem
+\startitem a multiple substitution replaces one glyph by one or more \stopitem
+\startitem a ligature substitution replaces multiple glyphs by one glyph \stopitem
+\startitem an alternate substitution replaces one glyph by one out of a set \stopitem
+\stopitemize
+
+Like it or not, but these categories are not always used as intended: they just
+are a way of replacing one or more glyphs by one or more other glyphs. This means
+that when for instance \type {ij} gets replaced by one glyph (given that the font
+supports it) a ligature substitution is used, even when in fact we have to do
+with a diftong that can be represented by one character.
+
+No matter what features you will use, keep in mind that they are nothing more
+than a combination of substitutions and positioning directives. So, the de facto
+standard ligature building feature \type {liga} indeed uses a ligature
+substitution, but other features with names that resemble no ligatures might use
+this substitution as well.
+
+An example of a single substitution is an oldstyle (\type {onum}) although it can
+as well be implemented as a choice out of alternate glyphs. Another example is
+smallcaps (\type {smcp}). Nowdays these are more or less standard features for a
+grown up font, while in the past they came as separate fonts. So, instead of loading
+an extra font, one sticks to one and selects the feature that does the
+substitution.
+
+A second category concerns relative positioning. Again we have several variants:
+
+\startitemize[packed]
+\startitem a single positioning moves a glyph over one of two axis and can change the width and|/|or height \stopitem
+\startitem a pair positioning also moved glyphs but concerns two adjacent glyphs \stopitem
+\startitem a cursive positioning operates on a range of glyphs and is used to visually connect them \stopitem
+\stopitemize
+
+In addition there are three ways to anchor marks onto glyphs:
+
+\startitemize[packed]
+\startitem a mark can be anchored on a base glyph \stopitem
+\startitem a mark can be anchored on a specific (visual) component of a ligature \stopitem
+\startitem a mark can be anchored on another mark \stopitem
+\stopitemize
+
+In base mode the single, alternate and ligature substitutions can rather easily
+be mapped onto the traditional \TEX\ font handling mechanism and this is what
+happens in base mode. A single substitution is just another instance of a glyph
+so there we just replace the original index into the glyph table by another one.
+In the case of an alternate we change the default index into one of several
+possible replacements in the alternate set. Ligatures can be mapped onto \TEX s
+ligature mechanism. The single positioning maps nicely on \TEX s kerning
+mechanism and pairwise positioning is not applicable in base mode. In node mode
+we don't do any remapping at loading time but delegate that to \LUA\ when
+processing the node lists.
+
+Marks are special in the sense that they normally only occur in scripts that also
+use substitution and positioning which in turn means that some more housekeeping
+is involved. After all, we need to keep track to what a mark applies. Of course a
+font can provide regular latin accents as marks but that is ill practice because
+cut and paste might not work out as expected. A proper font will support composed
+characters and provide glyphs that have the accents built in. Marks are not dealt
+with in base mode.
+
+Talking of complex scripts, the above set of operations is far from enough. Take
+for instance Arabic, where a sequence of 5~characters with 3~marks can easily
+become two glyphs glued together with two marks only. In the process we can have
+single substitutions, ligatures being built, marks being anchored and glyphs
+being cursively positioned. But, in order to do this well, some contextual
+analysis has to be done as well. Again we have several variants of this:
+
+\startitemize[packed]
+\startitem with contextual substitution a replacement takes place depending on a matching sequence of glyphs,
+optionally preceded or followed by matches \stopitem
+\startitem with contextual positioning shifting and anchoring happens based on a matching sequence of glyphs,
+optionally preceded or followed by matches \stopitem
+\startitem multiple contextual substitutions or positionings can be chained together \stopitem
+\startitem this can also happen in the reverse order (for right|-|to|-|left scripts) \stopitem
+\stopitemize
+
+In practice there is no fundamental difference between these and we can collapse
+them all in a sequence of lookups resulting in a sequence of whatever other
+manipulation is wanted.
+
+Given this, what is a feature? It's mostly a sequence of actions expressed in the
+above. And although there is a whole repertoire of semi|-|standardized features
+like \type {liga} and \type {onum}, there is no real hard coded support for them
+in \CONTEXT. Instead we have a generic feature processor that deals with all of
+them. A feature, say \type {abcd}, has a definition that boils down to a sequence
+of lookups. A lookup is just a name that is associated to one of the mentioned
+actions. So, \type {abcd} can do a decomposition (multiple substitution), then a
+replacement (single substitution) based on neighbouring glyphs, then do some
+ligature building (ligature substitution) and finally position the resulting
+glyphs relative to each other (like cursive positioning and anchoring marks).
+
+Imagine that we start out with 5 characters in the input. Instead of real glyphs
+we represent them by rectangles. The third one is a mark.

+
+The mark is an independent entity. Sometimes it has a width, sometimes it hasn't.
+In both cases we can position it. Here we move the shape left and down. There are

+we have one anchor per shape but there can be many.

+\startsubsection[title={Single substitution}]
+
+Single substitutions are probably the most used ones. For instance, when you
+ask for small caps, a lot of glyphs get replaced. When using oldstyle numerals
+only digits get replaced but even then each glyph has to be checked. This can be
+demonstrated with the Latin Modern fonts.
+
+\startlinecorrection

+\stoplinecorrection
+
+As you can see here, Latin Modern has an oldstyle dollar sign. If you don't like
+that one, you're in troubles as it comes with the rest of the oldstyles. The only
+way out is to apply the oldstyle numerals to digits only which involves more tagging
+than you might be willing to add. So, whenever you choose a substitution, be aware
+that you have not that much control over what gets substituted: it's the font that
+drives it. Here are some examples:

+\startsubsection[title={Multiple substitution}]
+
+In a multiple substitution a sequence of characters (glyphs) gets replaced by
+another sequence. In fact, you might wonder why one||to||one, multiple||to||one
+and multiple||to||multiple are not all generalized into this variant. Efficiency
+is probably the main reason. \footnote {Isn't it strange that complex mechanisms
+are designed to save a few bytes while at the same time we produce ridiculous
+large pictures with cameras.} For instance the many||to||one is often used for
+ligatures (\type {liga}) and as a consequence \type {liga} is often misused also
+for non||ligatures.
+
+One usage of multiple replacements is to avoid and or undo other replacements. In
+the next example we see a language dependent \type {fi} ligature. Take the dutch
+\type {ij} and \type {ie} diftongs. Here we need to prevent the \type {i}
+becoming combined with the \type {f} as it would look weird. Among the solutions
+for this are: context dependent ligatures (which involves a lot of rules), or
+multiple to multiple replacements (looking at the \type {fij} sequence).

+
+Of course from this result one cannot see what (combination of) substitution(s)
+was used, but it's a nice exercise to work out a solution.
+
+Multiple substitutions are mostly used for scripts more complex than latin or
+special fonts like Zapfino where advanced contextual analysis happens.
+
+\stopsubsection
+
+\startsubsection[title={Alternate substitution}]
+
+Alternates are simple one||to||one substitutions. Popular examples are small
+capitials and oldstyle numerals.
+
+A nice application of alternates is the punk font. This font is a Knuth original.
+As part of experimenting with the \METAPOST\ library in the early days of
+\LUATEX\ and \MKIV, runtime randomization was implemented. However, that variant
+used virtual fonts and was somewhat resource hungry. So, in a later stage Khaled
+Hosny made an \OPENTYPE\ version using \METAPOST\ output. Randomization is
+implemented through the \type {rand} feature.
+
+In \MKIV\ the \type {rand} feature is not really special and behaves just like
+any other (stylistic) alternate. The only difference is that for this feature a
+value of \type {yes} equals \type {random}. This also means that any feature that
+uses alternates use them randomly.

+
+There is one pitfall with random alternates: if each run leads to a different
+outcome, we can end up in oscillation: different shapes give different paragraphs
+and we can get more pages or cross references etc.\ that can end up differently
+so this is why \CONTEXT\ always uses the same random seed (which gets reset when
+you purge the auxiliary files.
+
+\stopsubsection
+
+\startsubsection[title={Ligature substitution}]
+
+A ligature is traditionally a combination of several characters into one. Popular
+ligatures are \quote {fi}, \quote {fl}, \quote {ffi} and , \quote {ffl}.
+Occasionally we see \quote {\ae}, \quote {\oe} and some more. Often ligatures are
+language dependant. For instance in languages like Dutch and German there can be
+compound words where one part ends with an \type {f} and the next part starts with
+an \type {f} and that looks bad or at least not intuitive. To some extent one
+can wonder if this tradition of ligatures is a good one. It definitely made
+sense ages ago, but I wouldn't be surprised if they are often added to fonts
+because the encoding vectors have them. After all, nothing prevents to go ahead
+and come up with way more ligatures.
+
+There can be many ligature features in a font. Although we support arbitrary
+features, that is: those not registered as being official one way or the other,
+the following are known by description:
+
+\startluacode
+context.starttabulate { "|lTCT{maincolor}|l|" }
+for k, v in table.sortedhash(fonts.handlers.otf.tables.features) do
+    if string.find(v,"ligature") then
+        context.NC()
+        context(k)
+        context.NC()
+        context(v)
+        context.NR()
+    end
+end
+context.stoptabulate()
+\stopluacode
+
+The \type {default} feature set has type {liga} as wel as the \TEX\ specific \type {tlig}
+that replaces successive hyphen signs into en- and emdashes. The \type {arabic} feature
+set also has \type {rlig} enabled.
+
+Now, there is one thing you should realize when we discuss specific features and
+the underlaying mechanisms: there is no real relationship between the features's
+name and the mechanisms used: any feature can use any underlying mechanism or
+combination. This is why deep down we see that what is internally called ligature
+gets used for any purpose where multiple||to||one replacements happen, and why the
+\type {liga} feature can use single substitutions or alternates to swap in
+another rendering so that the dot of the \type {i} stays free of the preceding
+\type {f}. And for some fonts relative positioning can be used to achieve a
+ligature effect.
+
+The next examples demonstrate how the \type {liga} feature deals with \type {ffi}.
+Possible solutions are: replace all three at once, replace the first two first and
+in a next step, combine a ligature and following character, replace one or more
+components by variants that have no interference with the dot of the~\quote{i}.

+Single positioning is also known as kerning, moving characters closer together so

+character that they apply to. Many fonts come with precomposed latin characters
+which means that an \type {à} in the input is mapped directly onto its
+corresponding shape. When the input contains an \type {a} followed by a \type{̀ }
+input normalization will normally turn this into an \type {à}. But, when this
+doesn't happen, the font machinery has to make sure that the mark gets positioned
+right onto the base character. In traditional \TYPEONE\ fonts that more or less
+happened automatically by overlaying the shapes. In \OPENTYPE\ (single)
+positioning is used to place the mark right.

+
+You can imagine that when marks are bound to characters that have become
+ligatures the anchoring is more complex as the font machinery has to keep track
+of onto which component the mark goes. For this purpose marks as well as base
+characters and base ligatures have anchors and feature lookups can explicitly
+refer to them.
+
+\stopsubsection
+
+\startsubsection[title={Contextual analysis}]
+
+What actually happens when turning a list of characters into a list of glyphs can
+range from real simple to pretty complex. For instance the \type {smcp} feature
+only has to run over the list and relate characters to a smallcaps shape. A
+slightly more complex feature might also demand some positioning. One step further
+is the use of contextual analysis, i.e. looking at previous, current and following
+characters (or glyphs). Because features can range from simple to complex the actual
+processing is not per feature! A font comes with a sequence of so called lookups that
+relate to a feature, script and language. Also, each feature can use one||to||one,
+multiple||to||one and many||to||many replacements as well as relative positioning.
+
+So, what actually happens is not that a feature is processed, but that all features
+are dealt with at the same time, in the order that the font prescribes. Enabling a
+specific feature means that a step is executed, while a disabled feature skips all
+steps that are tagged as belonging to that feature. And, as each feature can use
+contextual analysis, you can imagine that the effective sequence of actions can be
+a complex mix.
+
+A nice example of a contextual substitution is the centered period character in
+catalan in \type {ebgaramond}:
+
+\startbuffer
+\definefontfeature
+  [example]
+  [default]
+  [locl=yes,script=latn,language=cat]
+
+\definedfont[file:ebgaramond12-regular.otf*default at 40pt]l·l\quad
+\definedfont[file:ebgaramond12-regular.otf*example at 40pt]l·l
+\stopbuffer
+
+\typebuffer
+
+We show the boundingbox of the glyphs. The centered period between two l's is
+is replaced by a raised variant with no width.
+
+\blank \start \showglyphs \maincolor \midaligned{\getbuffer} \stop \blank
+
+It will be clear that in order to use such features you need to know what the font
+provides. For some fonts you need to explicitly enable the latin script (while others
+use default). Such a feature can be part of localized support but that is no rule.
+In that respect \OPENTYPE\ features are a rather unpredictable mess. For instance,
+nothing prevents such a feature to be a ligature, and in case you find that strange,
+especially ligature features are often abused for any purpose.
+
+\stopsubsection
+
+\startsubsection[reference=ligatures:hyphenation,title=Ligatures and hyphenation]
+
+In this section we will say a few words on how hyphenation interferes with
+(especially) ligature building. For this you need to know that:
+
+\starttyping
+effe
+\stoptyping
+
+But when hyphenation is permitted between the two \type{s}'s we actually have
+internally:
+
+\starttyping
+ef{-}{}{}fe
+\stoptyping
+
+The first snippet comes at the end of a line, the second at the beginning of a
+the next line and the last snippet is used when no hyphenation is needed. Such
+triplets need to be taken into account when we do replacements and positioning
+and also when we do contextual lookups.
+
+An \OPENTYPE\ font is just a container that collects the following:
+
+\startitemize[packed]
+\startitem
+    graphic representations of characters and symbols
+\stopitem
+\startitem
+    information about what characters the shapes represent
+\stopitem
+\startitem
+    rules about converting (sequences of) characters into one or more
+    representations
+\stopitem
+\startitem
+    rules about positioning representations relative to each other
+\stopitem
+\stopitemize
+
+Although the way this information is stored is standardized, the rules are not.
+You can imagine that there would be some standard way to turn an \type {f} and
+\type {i} into an \quote{fi} but we already saw that this is not the case. Here
+are some possibilities:
+
+\startitemize[packed]
+\startitem
+    The two characters get their own standard glyph, maybe with some kerning.
+\stopitem
+\startitem
+    The two characters are combined into one shape.
+\stopitem
+\startitem
+    The \type{f} gets a narrow representation and is kept close to the standard
+    \type{i}.
+\stopitem
+\startitem
+    A standard \type {f} is kerned with a dotless \type{i} (not to be confused
+    with the \UNICODE\ character).
+\stopitem
+\startitem
+    A special \type {f} is combined with a special \type {i}.
+\stopitem
+\stopitemize
+
+% maybe mark lig components when separate chars so that we can do spacing
+
+If the two characters are represented by their own shape, some contextual
+analysis takes place. Again there are several approaches to this:
+
+\startitemize[packed]
+\startitem
+    When an \type{f} is seen in the input, the next character is checked and one
+    or both gets replaced.
+\stopitem
+\startitem
+    When an \type{i} is seen in the input, the previous character is checked and
+    the \type {i} gets replaced.
+\stopitem
+\startitem
+    When an \type{f} several following characters are checked, for instance to
+    see if we need to take \type {ij} into account.
+\stopitem
+\stopitemize
+
+Traditionally the \type {f} followed by an \type{f}, \type{l} and \type{i} get a
+treatment, but some fonts also combine the \type {f} with \type {k}, \type {j},
+\type {b}, \type {t} and more.
+
+The \MKIV\ font handler is rather generic in the sense that it support what the
+font requires. However, a complication is that the scripts (languages) that use
+these diverse methods also expect hyphenation within such a ligature. Script like
+Arabic that are more demanding don't hyphenate so there interference with
+hyphenation is not a problem.
+
+Some ligatures are sensitive for languages. In languages that have compound words
+it might be undesirable to have a ligature at a word boundary, or in the Dutch
+word \type {fijn} we like to have a nice glyph (or combinations) for \type {ij}
+but no \type {fi} ligature. In a similar way hyphenation patterns can have
+rules and it will be no surprise that the hyphenation mechanism can compete with
+the ligature building for the best solution. This gets complicated by the fact
+that there is no real way to recognize in the font handler if we really are
+dealing with ligature building. Not only is the \type {liga} feature (and deep
+down the ligature gsub handling) not bound to ligatures (but simply a
+many|-|to|-|one mapper), some of the mentioned pseudo ligature builders use simple
+substitution and kerning and there is no way to recognize that as a ligature.
+
+Although it is possible to come up with a solution that is acceptable for many cases,
+there is no way to predict what kind of tricks font designers will use. A hyphenation
+point can be seen as follows:
+
+\starttabulate[||||]
+\NC \type{effe}      \NC \type{ef-fe}       \NC \type{e{f-}{f}{ff}e}       \NC \NR
+\NC \type{efficient} \NC \type{ef-fi-cient} \NC \type{e{ffi-}{}{ffi}cient} \NC \NR
+\stoptabulate
+
+In the second case the larger ligatures has replaced the previous one. We could
+have kept the first one because there are ways to manage two|-|step bounding
+ligatures but it's not worth the trouble (read: way more complex code and
+increased runtime for the whole mechanism). Here the \type {{ff}} and \type
+{{ffi}} can be individual shapes or just one shape.
+
+The three components of a hyphenation point: the pre, post and replacement text
+need to be looked at independently so that we get the proper kerning with the
+preceding and following characters. Also, in more complex (chained) lookups we
+need to compare each element with its surrounding. A fully expanded solution tree
+is too time consuming so we take some shortcuts and limits the checks to the
+level that it has no big impact on performance. The occasionally needed
+backtracking and inspection of components is currently quite reasonable. We need
+to trade quality with convenience: the result should look okay but processing
+speed should also be as high as possible. There is no need to let other scripts
+or regular fonts suffer too much from excessive script demands of fonts that
+could have be done better.
+
+The complication is that we not only need to check and replace but also need to
+check the kerning with preceding and following characters. We also need to take
+the hyphen into account (here one, but there can also be one after the break.
+
+It is for this reason that in \MKIV\ we have a (we think) acceptable mix of
+heuristics around hyphenation points that deal with single and multiple
+substitution as well as kerning. It will never be 100\% pertect but we consider
+it better to drop an occasional hyphenation in favor of proper font handling. In
+practice \TEX\ is clever enough to break a paragraph in lines within these
+restrictions.
+
+In \CONTEXT\ we have the traditional \TEX\ hyphenator but also provide an
+extensible \LUA\ reimplementation. That one might become the default in future
+versions. In traditional \TEX\ there are several low level hyphenation
+representations: simple hyphen only points, injected by the hyphenator,
+explicitly injected by the user or originating from a hyphen character. Then
+there is the generic (pre, post, replace) discretionary that can be explicitly
+injected by the user (or a macro). In \MKIV\ all hyphenation points get
+normalized to this generic discretionary. There is no need for old|-|time
+optimizations and a consistent (expanded) representation is easier to deal with
+in other extensions. However, because the font handler is supposed to also work
+outside \CONTEXT\ we need to deal with traditional cases too. But \unknown\ the
+results might differ a bit.

+    joiners, we get a four face symbol instead. The reason for having the joiners in
+    between is probably to avoid unexpected ligatures. The sequence \type {man},
+    \type {woman}, \type {boy}, \type {boy} gives \type {family}:
+    %

+    {\emoji\Girl}  = {\emoji\Man \zwj \Woman \zwj \Boy \zwj \Girl},
+    %
+    gives twin boys. Of course the real family emoj is {\emoji\char"1F46A}.
+
+    In our times for sure many combinations are possible, so:
+    %
+    {\emoji\Man}  + {\darkgray \type {zwj}}
+    {\emoji\Man}  + {\darkgray \type {zwj}}
+    {\emoji\Girl} + {\darkgray \type {zwj}}
+    {\emoji\Girl} = {\emoji\Man \zwj \Man \zwj \Girl \zwj \Girl},
+    %
+    indeed gives a family, but I wonder at what point cultural bias will creep into
+    font design. One can even wonder how clothing and haircut will demand frequent
+    font updates: {\emoji\char"1F46B}, {\emoji\char"1F46C}, {\emoji\char"1F46D}.
+
+    In the math alphabets we have a couple of annoying holes because some characters
+    were already present in \UNICODE. The bad thing here is that we now always have
+    to deal with these exceptions. But not so with emojis because here eventually all
+    variants will show up. Where a character \type {A} in red or blue uses the same
+    code point, a white telephone {\emoji\char"1F57E} and black telephone
+    {\emoji\char"1F57F} have their own. And because obsolete scripts are already
+    supported in \UNICODE\ and more get added, we can expect old artifacts also
+    showing up at some time. Soon the joystick {\emoji\char"1F579} will be an unknown
+    item to most of us, while the \MICROSOFT\ hololens migth get its slot.

+
+Goodies range from simple to complex. They share that they are defined in files
+and loaded at runtime. There is a good change that when you read this, that there
+are already more goodies than mentioned here. Here we will just mention a couple
+of goodies. More details can be found in the files that ship with \CONTEXT\ and
+have suffix \type {lfg}.
+
+A goodie file is a regular \LUA\ file and is supposed to return a table. This
+table collects data that is used for implementing the goodie or relates to a
+regular feature. It can also provide information that is used for patching a
+font. An example of a simple goodie file is the ones that accompanies the first
+release of the \OPENTYPE\ Lucida fonts.
+
+\starttyping
+return {
+  name = "lucida-opentype-math",
+  version = "1.00",
+  comment = "Goodies that complement lucida opentype.",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  mathematics = {
+    alternates = {
+      italic = {
+        feature = 'ss01',
+        value = 1,
+        comment = "Mathematical Alternative Italic"
+      },
+    }
+  }
+}
+\stoptyping
+
+This goodie file is only providing information about the meaning of a stylistic
+alternate. These have abstract tags like \type {ss01} and in this case this
+category collects alternative italic (calligraphic) shapes. Because math does
+not follow the same rules as text, this feature is enabled explicitly.
+
+In the goodie file of Xits math the alternates table has more entries:
+
+\startnarrowtyping
+alternates = {
+  cal       = { ... comment = "Mathematical Calligraphic Alphabet" },
+  greekssup = { ... comment = "Mathematical Greek Sans Serif Alphabet" },
+  greekssit = { ... comment = "Mathematical Italic Sans Serif Digits" },
+  monobfnum = { ... comment = "Mathematical Bold Monospace Digits" },

+  upint     = { ... comment = "Upright Integrals" },
+  vertnot   = { ... comment = "Negated Symbols With Vertical Stroke" },
+}
+\stopnarrowtyping
+
+An alternate is triggered at the \TEX\ end with:
+
+\starttyping
+$ABC$ $\cal ABC$ $\mathalternate{cal}\cal ABC$
+\stoptyping
+
+This is an example of a dynamic feature that gets applied when enabled at a
+specific location in the input. The \type {cal} is only recognized when it
+is defined in a goodies file, where the value is defined (in all of the above cases
+the value is~\type {1}).
+
+The Xits math fonts has a goodie files that starts with:
+
+\starttyping
+return {
+  name = "xits-math",
+  version = "1.00",
+  comment = "Goodies that complement xits (by Khaled Hosny).",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  mathematics = {
+    italics = {
+      ["xits-math"] = italics,
+    },
+    alternates = {
+\stoptyping
+
+Here the \type {italics} variable is a table defined before the \type {return}
+that looks as follows:
+
+\starttyping
+local italics = {
+  defaultfactor = 0.025,
+  disableengine = true,
+  corrections   = {
+   -- [0x1D44E] = 0.99,    -- a (fraction of quad)
+   -- [0x1D44F] = 100,     -- b (font points)
+      [0x1D453] = -0.0375, -- f
+  }
+}
+\stoptyping
+
+This rather specific table tells \CONTEXT\ that (when enabled) it has to apply
+italic correction. It disables support built into the \TEX\ engine (which in the
+case of \LUATEX\ is close to absent anyway). It will apply a default italic
+correction of \type {0.025} but for some shapes a different value is used. Again
+we have some commands at the \TEX\ end:
+
+\starttyping
+\setupmathematics[italics=1] % fontitalics
+\setupmathematics[italics=2] % fontdata
+\setupmathematics[italics=3] % quad based
+\setupmathematics[italics=4] % combination of 1 and 3
+\stoptyping
+
+Because (definitely at the start of the \LUATEX\ project) we had no
+proper \OPENTYPE\ math fonts, but at the same time wanted to move on
+to \OPENTYPE\ and \UNICODE\ math and no longer struggle with all
+those math families and definitions. The way out of this problem
+is to define a virtual math font. The code for doing this is built
+into the \MKIV\ core but is controlled by a goodie definition. Take
+for instance Antykwa Math:
+
+\startnarrowtyping

+\stopnarrowtyping
+
+Normally users will not define such tables but the keys give an indication of
+what is involved. The same is true for the previously shown tables: they are just
+provided in the \CONTEXT\ distribution.
+
+Text fonts also can have goodies. We start with a rather dumb one and there
+will be not that many of those. This one is needed to turn a \TYPEONE\ font
+with a rather special encoding into a \UNICODE\ font. The next mapping is
+possible because the dingbats are part of \UNICODE.
+
+\starttyping

+  name = "dingbats",

+      a100 = 0x275E,
+      a101 = 0x2761,
+      a102 = 0x2762,
+\stoptyping
+
+Applying this encoding happens in two steps. Because goodies like this are just
+features, we need to define a proper font feature set:
+
+\starttyping
+\definefontfeature
+  [dingbats]
+  [mode=base,
+   goodies=dingbats,
+   unicoding=yes]
+\stoptyping
+
+We have a base mode font, so no special processing takes place. The \type {goodies}
+key is used to communicate the goodies file. The \type {unicoding} key is used
+to apply the encoding. Of course this only works because the remapper code is present
+in the core and is hooked in to the font initialization code. The \type {dingbats}
+feature set is predefined, just as the font definition:
+
+\starttyping
+\definefontsynonym [ZapfDingbats] [file:uzdr] [features=dingbats]
+\stoptyping
+
+Here is a goodie file that I made a while ago:
+
+\starttyping
+return {
+  name = "oxoniensis",
+  version = "1.00",
+  comment = "Oxoniensis test file for Thomas Schmitz.",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  features = {
+    lunatesigma = {
+      type = "substitution",
+      data = {
+        sigma  = 0x03F2,
+        sigma1 = 0x03F2,
+        Sigma  = 0x03F9,
+        phi    = phi1,
+      },
+    }
+  },
+}
+\stoptyping
+
+There is not that much to say about this, apart from that it's a sort of fake
+feature that gets enabled as regular one:
+
+\starttyping
+\definefontfeature[test]
+  [mode=node,
+   kern=yes,
+   lunatesigma=yes,
+   goodies=oxoniensis]
+
+\definefont[somefont][file:oxoniensis*test]
+\stoptyping
+
+A complete different kind of goodie is the following. At one of the \CONTEXT\ meetings
+Mojca Miklavec discussed the possibility to have an additional mechanism for
+defining combinations of fonts. Often fonts come in a set of four (regular, italic,
+bold and bold italic). In \MKII\ the complexity of typescripts depends on the amount of
+encodings that need to be supported but in \MKIV\ things are easier. For a set of four fonts
+a typescript looks as follows:
+
+\starttyping
+\starttypescript [sans] [somesansfont] [name]
+  \setups[font:fallback:sans]
+  \definefontsynonym [Sans]           [file:somesans]  [features=default]
+  \definefontsynonym [SansBold]       [file:somesansb] [features=default]
+  \definefontsynonym [SansItalic]     [file:somesansi] [features=default]
+  \definefontsynonym [SansBoldItalic] [file:somesansz] [features=default]
+\stoptypescript
+\stoptyping
+
+We still have the abstract notion of a \type {Sans} font so that we can refer to
+the regular shape without knowing the real name but the number of lines needed
+is small. Such a definition can then be referred to using:
+
+\starttyping
+\starttypescript[somefontset]
+  \definetypeface [somefontset] [rm] [serif] [someserif] [default]
+  \definetypeface [somefontset] [ss] [sans]  [somesans]  [default]
+  \definetypeface [somefontset] [tt] [mono]  [somemono]  [default]
+  \definetypeface [somefontset] [mm] [math]  [somemath]  [default]
+\stoptypescript
+\stoptyping
+
+So far things look simple. Given that many fonts follow a similar naming scheme
+Wolfgang made a module that avoids such definitions altogether. However, being
+involved in the development of the Antykwa fonts, Mojca ran into the situation
+that not just four fonts were part of the set but many more. There are several
+weight (think of light and heavy variants) as well as condensed variants and of
+course the whole set is not per se a multiple of four.
+
+In the meantime, in addition to the \type {file:} and \type {name:} accessors,
+\CONTEXT\ had an additional one tagged \type {spec:} where a string made out of
+weight, style, width etc.\ is turned into a (best guessed) font name. Therefore
+the most natural way to deal with the many|-|fonts|-|in|-|a|-|set dilemma was to
+provide an additional interface between this specification and the font set and
+the most robust method was to define all in a goodie file.
+
+In this case the goodies are loaded independent of the font, that is: not
+as a feature. For instance:
+
+\starttyping
+\loadfontgoodies[antykwapoltawskiego]
+\stoptyping
+
+This file maps obscure fontnames onto the \type {spec:} interface so that
+we can access them in a robust way.
+
+\starttyping
+\definefont
+  [MyFontA]
+  [file:Iwona-Regular*smallcaps]
+\definefont
+  [MyFontB]
+  [file:AntykwaTorunska-Regular*smallcaps]
+\definefont
+  [MyFontC]
+  [file:antpoltltcond-regular*smallcaps]
+\definefont
+  [MyFontD]
+  [spec:antykwapoltawskiego-bold-italic-condensed-normal*smallcaps]
+\definefont
+  [MyFontE]
+  [spec:antykwapoltawskiego-bold-italic-normal]
+\stoptyping
+
+The goodies file looks as follows:
+
+\starttyping
+return {
+  name = "antykwa-poltawskiego",
+  version = "1.00",
+  comment = "Goodies that complement Antykwa Poltawskiego",
+  author = "Hans & Mojca",
+  copyright = "ConTeXt development team",
+  files = {
+    name = "antykwapoltawskiego", -- shared
+    list = {
+      ["AntPoltLtCond-Regular.otf"] = {
+        weight = "light",
+        style  = "regular",
+        width  = "condensed",
+      },
+      ...
+      ["AntPoltExpd-BoldItalic.otf"] = {
+        weight = "bold",
+        style  = "italic",
+        width  = "expanded",
+      },
+    },
+  },
+  typefaces = {
+    ["antykwapoltawskiego-light"] = {
+      shortcut     = "rm",
+      shape        = "serif",
+      fontname     = "antykwapoltawskiego",
+      normalweight = "light",
+      boldweight   = "medium",
+      width        = "normal",
+      size         = "default",
+      features     = "default",
+    },
+    ...
+  },
+}
+\stoptyping
+
+In addition to the files|-|to|-|specification mapping, there is
+also a typeface specification table. This permits the definition
+of a typeface in the following way:
+
+\starttyping
+\definetypeface
+  [name=mojcasfavourite,
+   preset=antykwapoltawskiego,
+   normalweight=light,
+   boldweight=bold,
+   width=expanded]
+
+\setupbodyfont
+  [mojcasfavourite]
+\stoptyping
+
+When resolving the definition, the best possible match will be taken from the
+typeface table in the goodie file. Of course this is not something that we expect
+the average user to deliver and deal with.
+
+As the Antykwa font is somewhat atypical and not used in everyday typesetting,
+you might wonder if all this overhead makes sense. However, there are type
+foundries that do ship their fonts in many weights and for those using a \LUA\
+goodie file instead of many typescripts in \TEX\ coding makes sense. Take for
+instance TheMix:
+
+\starttyping
+\loadfontgoodies
+  [themix]
+
+\definetypeface
+  [name=themix,
+   preset=themix-light]
+
+\definetypeface
+  [name=themix,
+   preset=themixmono-light]
+
+\setupbodyfont
+  [themix]
+\stoptyping
+
+In this case the goodie file can serve as a template for more such fonts.
+In order to be efficient this goodie file uses a couple of local
+tables (we could have used metatables instead).
+
+\starttyping
+local themix = {
+  name     = "themix",
+  shortcut = "ss",
+  shape    = "sans",
+  fontname = "themix",
+  width    = "normal",
+  size     = "default",
+  features = "default",
+}
+
+local themixmono = {
+  name     = "themixmono",
+  shortcut = "tt",
+  shape    = "mono",
+  fontname = "themixmono",
+  width    = "normal",
+  size     = "default",
+  features = "default",
+}
+\stoptyping
+
+The main goodie table defines a lot of weights:
+
+\startnarrowtyping
+return {
+  name = "themix",
+  version = "1.00",
+  comment = "Goodies that complement TheMix (by and for sale at www.lucasfonts.com).",

+
+This demo file implements several goodies: featuresets, colors and
+postprocessors. Keep in mind that a goodie file can provide whatever information
+it wants but of course only known subtables will be dealt with.
+
+The coloring of glyphs can happen by name, which assumes that glyph names are
+used, or by number. Here we use generic glyph names, but for a specific font one
+might need to provide a special goodie file. For instance, the color section of
+the goodie file for the husayni font has entries like:
+
+\startnarrowtyping
+[3] = {
+  "Ttaa.waqf", "SsLY.waqf", "QLY.waqf", "Miim.waqf", "LA.waqf", "Jiim.waqf",
+  "Threedotsabove.waqf", "Siin.waqf", "Ssaad.waqf", "Qaaf.waqf", "SsL.waqf",
+  "QF.waqf", "SKTH.waqf", "WQFH.waqf", "Kaaf.waqf", "Ayn.ruku", "Miim.nuun_high",
+  "Siin.Ssaad", "Nuunsmall", "emptydot_low", "emptydot_high", "Sifr.fill",
+  "Miim.nuun_low", "Nuun.tanwiin",
+},
+\stopnarrowtyping
+
+Of course such a definition can only be made when the internals of the font are
+known and in this case it concerns a pretty complex font.

+    }
+}
+\stoptyping
+
+This is much shorter (and efficent) that defining a whole vector, as in:
+
+\starttyping
+local f_uni_base = string.formatters["uni%04X"]
+local f_uni_plus = string.formatters["uni%04X.y%s"]
+
+local function range(first,last)

+    }
+}
+\stoptyping
+
+By using names we don't depend on \UNICODE\ which sometimes is needed when glyphs
+have ended up in the private space. However, by default, after glyphs have been
+mapped to colors, an extra pass will make sure that characters pushed into
+private space will get the same mapping as their regular \UNICODE\ has gotten
+(given that the number is known). Of course explicitly assigned colors will be
+preserved.
+
+Another generic demo feature is postprocessing. In principle one can
+add additional postprocessors but for that the source code needs to
+be consulted which in turn assumes some knowledge of fonts and \CONTEXT\
+internals.
+
+\startbuffer

+
+The statistics just print some font parameters to the log so that one
+is not showing up here. The squeeze looks as follows:
+
+\startbuffer

+    \ruledhbox{\color[maincolor]{DemoFontE height \& depth}}
+\egroup
+\stoplinecorrection
+
+The squeezer just makes the height and depth of glyphs a  bit smaller and it is
+not that hard to imagine other manipulations. The demo goodie file is good
+place to start playing with such things.
+
+Because there is less standardization with respect to features than one might
+suspect, goodie files provide a mean to define featuresets. We can use such a set
+in another definition:
+
+\starttyping
+\definefontfeature
+  [demo-smallcaps]
+  [goodies=demo,
+   featureset=smallcaps]
+\stoptyping
+
+Of course this only makes sense for more complex combinations. The already mentioned
+husayni font comes with many features and most of these work together.
+
+The basic goodie table looks as follows:
+
+\startnarrowtyping
+return {
+  name         = "husayni",
+  version      = "1.00",
+  comment      = "Goodies that complement the Husayni font by Idris Samawi Hamid.",
+  author       = "Idris Samawi Hamid and Hans Hagen",
+  featuresets  = { },
+  solutions    = { },
+  stylistics   = { },
+  colorschemes = { },
+}
+\stopnarrowtyping
+
+We already saw the color schemes and now we will fill in the other tables. First
+we define a couple of sets:
+
+\startnarrowtyping
+local basics = {
+  analyze  = "yes",
+  mode     = "node",
+  language = "dflt",

+\stopnarrowtyping
+
+Next we define some featuresets and we use the default as starting point:
+
+\startnarrowtyping
+  featuresets = {
+    default = {
+      default,
+    },
+    minimal_stretching = {
+      default, js11 = "yes", js03 = "yes",

+      ss06 = "yes", ss09 = "yes",
+    },
+  }
+\stopnarrowtyping
+
+When defining the font at the \TEX\ end we can now refer to for instance \type
+{wide_all} which saves us some typing. However, it does not stop here. In a later
+paragraph we will see how fonts can work in tandem with the parbuilder. For that
+purpose the goodie table has a \type {solutions} subtable:
+
+\startnarrowtyping
+solutions = {
+  experimental = {
+    less = {
+      "shrink"
+    },
+    more = {
+      "minimal_stretching", "medium_stretching", "maximal_stretching", "wide_all"
+    },
+  },
+}
+\stopnarrowtyping
+
+Here we define an experimental solution for optimizing the lines in a paragraph:
+we can narrow words or we can widen them according to a specific featureset. In
+order to reach the optimal solution the text will be retypeset under a different
+feature regime.

+
+Because there are a some 55 stylistic and 21 justification variants the
+goodie file also provides a \type {stylistics} table and for tracing purposes
+the {colorschemes} table is populated.
+
+Yet another demonstration of manipulation is the following. Not all fonts come
+with all combined glyphs. Although we have an auto|-|compose feature in \CONTEXT\
+it sometimes helps to be specific with respect to some combinations. This is
+where the \type {compositions} goodie kicks in:
+
+\starttyping
+local compose = {
+  [0x1E02] = {
+    anchored = "top",
+  },
+  [0x1E04] = {
+    anchored = "bottom",

+      },
+      bottom = {
+        x = 300,
+        y = -30,
+      },
+    },
+  },
+  [0x0307] = {

+  compositions = {
+    ["lmroman12-regular"] = compose,
+  }
+}
+\stoptyping
+
+Of course this assumes some knowledge of the font metrics (in base points) and
+\UNICODE\ slots, but it might be worth the trouble. After all, one only needs to
+figure it out once. But keep in mind that it will always be a kludge.
+
+A slightly different way to define such compositions is the following:
+
+\starttyping
+local defaultunits = 193 - 30
+
+local compose = {
+                 DY = defaultunits,
+ -- [0x010C] = { DY = defaultunits }, -- Ccaron
+ -- [0x02C7] = { DY = defaultunits }, -- textcaron
+}
+
+-- fractions relative to delta(X_height - x_height)
+
+local defaultfraction = 0.85
+
+local compose = {
+  DY = defaultfraction, -- uppercase compensation
+}
+
+return {
+  name = "lucida-one",
+  version = "1.00",
+  comment = "Goodies that complement lucida.",
+  author = "Hans and Mojca",
+  copyright = "ConTeXt development team",
+  compositions = {
+    ["lbr"]  = compose,
+    ["lbi"]  = compose,
+    ["lbd"]  = compose,
+    ["lbdi"] = compose,
+  }
+}
+\stoptyping
+
+Of course no one really needs this because \OPENTYPE\ Lucida fonts
+have replaced the \TYPEONE\ versions.
+
+The next goodie table is dedicated to the de facto standard \TEX\ font Latin
+Modern. There is a bit of history behind this file. When we started writing
+\CONTEXT\ there were not that many fonts available and so we ended up with a font
+system that was rather well suited for the predecessor of Latin Modern, called
+Computer Modern. And because these fonts came in design sizes the font system
+was made such that it could cope efficiently with many files in a font set. Although
+there is no additional overhead compared to small font sets, apart from more files,
+there is some burden in defining them. And, as they are the default fonts, these
+definitions slow down the initialization of \CONTEXT\ (which is due to the fact that
+the large typescript definitions were loaded and parsed). So, at some point
+the decision was made to kick out these definitions and move the burden of figuring
+out the right size to \LUA. When Latin Modern is chosen as font the effect is the
+same when design sizes are enabled. But, instead of many definitions (one for each
+combination of size and style) we now have an option. A non|-|designsize typeface
+is defined as follows:
+
+\startnarrowtyping
+\starttypescript [modern,modern-base]
+  \definetypeface [\typescriptone] [rm] [serif] [modern] [default]
+  \definetypeface [\typescriptone] [ss] [sans]  [modern] [default]
+  \definetypeface [\typescriptone] [tt] [mono]  [modern] [default]
+  \definetypeface [\typescriptone] [mm] [math]  [modern] [default]
+  \quittypescriptscanning
+\stoptypescript
+\stopnarrowtyping
+
+The designsize variant looks like this:
+
+\startnarrowtyping
+\starttypescript [modern-designsize]
+  \definetypeface [\typescriptone]
+    [rm] [serif] [latin-modern-designsize] [default] [designsize=auto]
+  \definetypeface [\typescriptone]
+    [ss] [sans]  [latin-modern-designsize] [default] [designsize=auto]
+  \definetypeface [\typescriptone]
+    [tt] [mono]  [latin-modern-designsize] [default] [designsize=auto]
+  \definetypeface [\typescriptone]
+    [mm] [math]  [latin-modern-designsize] [default] [designsize=auto]
+  \quittypescriptscanning
+\stoptypescript
+\stopnarrowtyping
+
+Of course there are accompanying typescripts that map the sans, serif, mono
+and math styles onto files. The \type {designsize} magic uses the following
+table. We show only part of the file, as it is in the \CONTEXT\ distribution.
+
+\starttyping

+\stoptyping
+
+The \type {auto} option will choose a best fit compatible to the
+\MKII\ implementation. When \type {default} is used instead, the
+default filename will be taken. Of course one might wonder if
+there will ever be similar goodie files because design sizes
+are not that popular nowadays.
+
+Not all fonts are perfect and of course the \LUATEX\ engine can have flaws as
+well. For this reason we can implement patches. Here is another example of a
+goodie file that has some more code than just a table:
+
+\starttyping
+local patches = fonts.handlers.otf.enhancers.patches
+
+local function patch(data,filename,threshold)
+  local m = data.metadata.math
+  if m then
+    local d = m.DisplayOperatorMinHeight or 0
+    if d < threshold then
+      patches.report("DisplayOperatorMinHeight(%s -> %s)",d,threshold)
+      m.DisplayOperatorMinHeight = threshold
+    end
+  end
+end
+
+patches.register("after","analyze math","asana",
+    function(data,filename) patch(data,filename,1350) end)
+
+local function less(value,target,original)
+  return 0.25 * value
+end
+
+local function more(value,target,original)
+  local o = original.mathparameters.DisplayOperatorMinHeight
+  if o < 2800 then
+      return 2800 * target.parameters.factor
+  else
+      return value -- already scaled
+  end
+end
+
+return {
+  name = "asana-math",
+  version = "1.00",
+  comment = "Goodies that complement asana.",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  mathematics = {
+    parameters = {
+      DisplayOperatorMinHeight         = more,
+      StackBottomDisplayStyleShiftDown = less,
+      StackBottomShiftDown             = less,
+      StackDisplayStyleGapMin          = less,
+      StackGapMin                      = less,

+      StretchStackGapBelowMin          = less,
+      StretchStackTopShiftUp           = less,
+    }
+  }
+}
+\stoptyping
+
+In fact, in addition to already mentioned \type {mapfiles} and
+\type {virtuals} subtables, we can pass variables and
+overload parameters.
+
+\starttyping
+return {
+  name = "lm-math",
+  ...
+  mathematics = {
+    mapfiles = {
+      ...

+    variables = {
+      joinrelfactor = 3, -- default anyway
+    },
+    parameters = { -- test values
+     -- FactorA = 123.456,
+     -- FactorB = false,
+     -- FactorC = function(value,target,original)
+     --   return 7.89 * target.factor

+}
+\stoptyping
+
+This kind of goodie functionality is typical for the development of \LUATEX\ and
+experimental math fonts and no user should ever be bothered with it. However, it
+demonstrates that we're not stuck with only features built in the fonts.
+
+% mathdimensions
+
+It can be that a user is not satisfied by some aspects of a math font design.
+There is not much that we can do about the shapes, but we can manipulate for
+instance dimensions.
+
+For this there are two mechanism available: automatically applied dimensional
+fixes and a \type {mathdimensions} feature. Both work with the same goody
+specification.
+
+\starttyping
+mathematics = {
+  ...
+  dimensions = {
+  },
+  ...
+}
+\stoptyping
+
+The entries in a dimensions table are tables themselves. There can be many
+of them so one can organize dimensional tweaks in groups. The \type {default}
+group is always applied, while others are applied on demand. Say that want
+to tweak all \type {±} and \type {∓}. \footnote {In fact, this mechanism is a
+a response to a mail on the \CONTEXT\ mailing list.}
+
+\starttyping
+mathematics = {
+  dimensions = {
+    default = {
+      [0x00B1] = { -- ±
+        height = 500,
+        depth  = 0,
+      },
+      [0x2213] = { -- ∓
+        height = 500,
+        depth  = 0,
+      },
+    },
+  },
+}
+\stoptyping
+
+This will give these two characters a different height and depth. However, this
+will not have much effect in rendering (much larger dimensions might have).
+
+\starttyping
+mathematics = {
+  dimensions = {
+    default = {
+      [0x00B1] = { -- ±
+        yoffset =  100,
+      },
+      [0x2213] = { -- ∓
+        yoffset = -100,
+      },
+    },
+  },
+}
+\stoptyping
+
+This will raise and lower the glyphs in their bounding boxes and give them
+an appearance more close to their ancestors. But defined this way, they are
+always applied and that might not be what we  want. So, we can do this:
+
+\starttyping
+mathematics = {
+  dimensions = {
+    signs = {
+      [0x00B1] = { -- ±
+        yoffset =  100,
+      },
+      [0x2213] = { -- ∓
+        yoffset = -100,
+      },
+    },
+  },
+}
+\stoptyping
+
+This time the application is feature driven. As with all features, setting them
+up has to happen {\em before} fonts are loaded. This will do the trick:
+
+\starttyping
+\definefontfeature [lm-math] [mathdimensions=signs]
+\stoptyping
+
+The \type {lm-math} feature is not defined by default but can be used for such
+purposes. It {\em is} defined with the fontname:
+
+\starttyping
+\definefontsynonym
+  [LMMathRoman-Regular]
+  [file:latinmodern-math-regular.otf]
+  [features={math\mathsizesuffix,lm-math},
+   goodies=lm]
+\stoptyping
+
+A rather specialized goodie is the one that is used to specify math cut|-|ins. A
+good quality math font has these kerns already defined but even then you might
+want to add or replace some by your own. Here is an example of such a patch.
+Normally there are multiple goodies defined in one file but we only show kerns
+here:
+
+\starttyping
+local kern_200 = { bottomright = { { kern = -200 } } }
+local kern_100 = { bottomright = { { kern = -100 } } }
+
+return {
+    name = "pagella-math",
+    version = "1.00",
+    comment = "Goodies that complement pagella.",
+    author = "Hans Hagen",
+    copyright = "ConTeXt development team",
+    mathematics = {
+        kerns = {
+            [0x1D449] = kern_200, -- math italic V
+            [0x1D44A] = kern_100, -- math italic W
+        },
+    },
+}
+\stoptyping
+
+As with other goodies the file is loaded with:
+
+\starttyping
+\definefontsynonym
+  [MathRoman]                     % names used in definitions
+  [file:texgyrepagella-math.otf]  % the file to be loaded
+  [features=math\mathsizesuffix,  % size dependent features
+   goodies=pagella-math]          % the goodie file to be applied
+\stoptyping
+
+This is typically a goodie that is always applied and not driven by a feature.
+After all, the values given are passed to the engine (after being scaled).
+
+Most goodies are bound to fonts of collections of fonts. This is different for
+treatments. These ship with the distribution but you can also provide your own.
+As this is still somewhat experimental we just mention a few aspects. The entries
+are filenames that point to tables.
+
+\starttyping
+return {
+  name = "treatments",
+  version = "1.00",
+  comment = "Goodies that deals with some general issues.",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  treatments = {
+    ["adobeheitistd-regular.otf"] = {
+      embedded = false, -- not yet used
+      comment  = "this font is part of acrobat",
+    },
+    ["crap.ttf"] = {
+      ignored = true,
+      comment = "a text file with suffix ttf",
+    },
+    ["latinmodern-math.otf"] = {
+      comment = "experimental",
+    },
+    ["rubish-regular.ttf"] = {
+      comment = "check output for missing à and á",
+    }
+  },
+}
+\stoptyping
+
+The comment entry in such a table becomes part of the message at the end
+of a run:
+
+\startnarrowtyping
+mkiv lua stats  > loaded fonts: 2 files: latinmodern-math.otf (experimental), lmroman12-regular.otf
+\stopnarrowtyping
+
+The ignored flag signals the font name database builder to ignore the file. This
+means that the font can still be known as file, but that its (name based)
+properties are not collected. As you asked explicitly for a file, the file can
+still be loaded. You can use this trick to avoid issues with the database builder
+in case of a problematic file, but a real run will still try to load the file. After
+all, you get what you ask for. If loading and usage is successful you get at least
+the message reported at the end of the run.
+
+\stopsection
+
+\startsection[title=Analyzers]
+
+An \OPENTYPE\ font is kind of special in the sense that it provides some
+information on how to turn sequences of characters into sequences of glyphs. In
+fact, if all fonts had a reasonable repertoire of glyphs most of the information
+that concerns combining, remapping and shuffling the input and|/|or mapping onto
+glyphs could as well happen in the renderer. This means that fonts have many of
+their internal features tables in common, or more precisely could share many gsub
+related issues, if only there had been some predefined sets of substitutional
+features.
+
+So, for most of the time, a feature processor just does what the font demands and
+the font provides the information. There are however a few cases where font only
+provide part of the logic. Take for instance the \type {init}, \type {medi},
+\type {fina} and \type {isol} features that relate to positions in the word: the
+start, the end, in the middle or isolated. For these features to work the engine
+has to provide information about the state of a character (glyph) and this is where
+analysis kicks in. Just watch this:
+
+\startbuffer
+\definefontfeature
+  [default-with-analyze]
+  [default]
+  [script=latn,mode=node,
+   init=yes,medi=yes,fina=yes,isol=yes]

+\showotfcomposition
+  {dejavu-serif*default-with-analyze at 24pt}
+  {}
+  {I don't wanna know tha\utfchar{"300}t!}
+\stopbuffer
+
+\typebuffer
+
+In the tracer the different categories are colored. This kind of information is
+especially important for typesetting Arabic. Normally \CONTEXT\ can figure out
+itself when this is needed so you don't have to worry too much about this kind of
+additional actions.

+
+There are a lot of tracing options in \MKIV, but most will never be seen by users. Most
+are enabled using the tracker mechanism. Some have a bit more visibility and have a dedicated
+command to trigger them.
+
+When something is going terribly wrong, you will always get a message but sometimes even an
+end|-|user has to request for more information. An example are missing characters. There are
+several ways to get them reported:
+
+\starttyping
+\enabletrackers[fonts.missing=replace]
+\enabletrackers[fonts.missing=remove]
+\enabletrackers[fonts.missing]
+\stoptyping
+
+For historic reasons we also have:
+
+\starttyping
+\checkcharactersinfont
+\removemissingcharacters
+\replacemissingcharacters
+\stoptyping
+
+which happens automatically when you enable the tracker. There is some extra
+overhead involved so you might want to turn on this feature on only if you really

+\startsection[title=Some remarks]
+
+If you talk about features and fonts it is not difficult to end up speaking
+\OPENTYPE . However, in \CONTEXT\ we use the term in a more general way, if only
+because we provide more features. In traditional \TEX\ we have a few features:
+ligatures, smallcaps and kerns, and to some extent we can see oldstyle numerals
+also as feature. It is however important to notice that in \OPENTYPE\ ligatures
+are just a synonym for combining multiple characters into on. From the user
+interface point of view these operations are grouped into \type {liga}, \type
+{dlig}, \type {clig} and \type {rlig} and for \TEX ies we have \type {tlig}. The
+distinction is not as clear as one might think: any feature can use the ligature
+builder. And as a consequence we see that happen too, for instance some fonts use
+\type {ccmp} for constructing mandatory ligatures.
+
+Some of these interpretations (or maybe even tricks) are side effects of for
+instance user interfaces. If one can for instance not turn on or off the \type
+{ccmp} feature, but can do that for \type {liga}, then one way to keep some
+ligatures in for instance letter spaced text, is to put them into \type {ccmp},
+assuming that this one will always be enabled. Eventually that then becomes a
+sort of standard. Personally I don't like such pseudo standards but we have to
+live with them.
+
+Another example of such a standard is the used of non breakable spaces to
+influence treatment of some Devanagari characters. Where \UNICODE\ has special
+characters to influence mechanisms that combine and replace characters, the lack
+of some triggers others to be used and eventually that becomes a standard.
+Similar ambiguities arise with math: we have no way to indicate math (while we do
+have ways to indicate a change in writing order).
+
+Talking of math, take \OPENTYPE\ math: at some point there is a draft, that then
+gets implemented in one word processor using one font, but omissions or
+imperfections that surface (maybe because more fonts and engines are developed)
+stay around because the initial implementation is published and frozen, simply
+because there are many users that stick to expectations. Where \TEX ies accept a
+few years of development, this is not true for commercial applications. \footnote
+{Of course \HTML\ is the biggest example of this: we're stuck forever with open
+tags without close tags, mixed uppercase and lowercase tags, attributes without
+value or values without quotes.}
+
+So, although there is without doubt progress, some annoyances stay. The \TEX\
+community has always been able to adapt, and this is one reason why a \LUA\
+implementation is nice: it gives room for experiments, extensions, variants, etc.
+Of course it also makes a bit more independent, although one may wonder if that
+matters any longer in a rapidly changing world. The original idea behind \TEX,
+that it should be useable for ages, will survive, but users might see more
+changes in a lifetime than foreseen when \TEX\ showed up.

+
+\startsection[title=Introduction]
+
+In this chapter the font formats as we know them will be introduced. The
+descriptions will be rather general but more details can be found in the
+appendix. Although in \MKIV\ we do support all these types eventually the focus
+will be on \OPENTYPE\ fonts but it does not hurt to see where we are coming from.
+
+\stopsection
+
+\startsection[title=Glyphs]
+
+A typeset text is mostly a sequence of characters turned into glyphs. We talk of
+characters when you input the text, but the visualization involves glyphs. When
+you copy a part of the screen in an open \PDF\ document or \HTML\ page back to
+your editor you end up with characters again. In case you wonder why we make this
+distinction between these two states we give an example.
+
+\startplacefigure [location=here,reference=fig:character-glyph,title=From characters to glyphs.]
+    \startcombination
+        {\color[maincolor]{\definedfont[Serif*default       at 30pt]affiliation}} {upright}
+        {\color[maincolor]{\definedfont[SerifItalic*default at 30pt]affiliation}} {italic}
+    \stopcombination
+\stopplacefigure
+
+We see here that the shape of the \type {a} is different for an upright serif and
+an italic. We also see that in \type {ffi} there is no dot on the \type {i}. The
+first case is just a stylistic one but the second one, called a ligature, is
+actually one shape. The 11 characters are converted into 9 glyphs. Hopefully the
+final document format carries some extra information about this transformation so
+that a cut and paste will work out well. In \PDF\ files this is normally the
+case. In this document we will not be too picky about the distinction as in most
+cases the glyph is rather related to the character as one knows it.
+
+So, a font contains glyphs and it also carries some information about
+replacements. In addition to that there needs to be at least some information
+about the dimensions of them. Actually, a typesetting engine does not have to
+know anything about the actual shape at all.

+
+The rectangles around the shapes \in {figure} [fig:glyph-dimension-normal] and \in
+{figure} [fig:glyph-dimension-italic] are called boundingbox. The dashed line
+reflects the baseline where they eventually are aligned onto next to each other.
+The amount above the baseline is called height, and below is called depth. The
+piece of the shape above the baseline is the ascender and the bit below the
+descender. The width of the bounding box is not by definition the width of the
+glyph. In \TYPEONE\ and \OPENTYPE\ fonts each shape has a so called advance width
+and that is the one that will be used.

+
+Another traditional property of a font is kerning. In \in {figure}
+[fig:glyph-kerns] you see this in action. These examples
+demonstrate that not all fonts need (or provide) the same kerns
+(in points).
+
+So, as a start, we have now met a couple of properties of a font.
+They can be summarized as follows:
+
+\starttabulate[|l|p|]
+\NC mapping to glyphs   \EQ characters are represented by a shapes that have recognizable
+                            properties so that readers know what they mean \NC \NR
+\NC ligature building   \EQ a sequence of characters gets mapped onto one glyph \NC \NR
+\NC dimensions          \EQ each glyph has a width, height and depth \NC \NR
+\NC inter-glyph kerning \EQ optionally a bit of positive or negative space has to be inserted between glyphs \NC \NR
+%NC italic correction   \EQ a correction is applied between an oblique shape and what follows \NC \NR
+\stoptabulate
+
+Regular font kerning is hardly noticeable and improves the overall look of the
+page. Typesetting applications sometimes are capable of inserting additional
+spaces between shapes. This more excessive kerning is not that much related to
+the font and is used for special purposes, like making a snippet of text stand
+out. In \CONTEXT\ this kind of kerning is available but it is a font independent
+feature. Keep in mind that when applying that kind of rather visible kerning
+you'd better not have ligatures and fancy replacements enabled as \CONTEXT\
+already tries to deal with that as good as possible.
+
+\stopsection
+
+\startsection[title=The basic process]
+
+In \TEX\ a font is an abstraction: the engine only needs to know about the
+mapping from characters to glyphs, what the width, height and depth is, what
+sequences need to be translated into ligatures and when kerning has to be
+applied. If for the moment we forget about math, these are all the properties
+that matter and this is what the \TEX\ font metric files that we see in the next
+section provide.
+
+Because one of the principles behind \LUATEX\ is that the core engine (the
+binary) stays small and that new functionality is provided in \LUA\ code, the
+font subsystem largely looks like it always has been. As users will normally use
+a macro package most of the loading will be hidden from the user. It is however
+good to give a quick overview of how for instance \PDFTEX\ deals with fonts using
+traditional metric files.

+\stopplacefigure
+
+The input (bytes) gets translated into characters by the input parser. Normally
+this is a one|-|to|-|one translation but there are examples of some translation
+taking place. You can for instance make characters active and give them a
+meaning. So, the eight bit represention of an editors code page \type {ë} can
+become something else internally, for instance a regular \type {e} with an \type
+{¨} overlayed. It can also become another character, which in the code page
+would be shown as \type {á} but the user will not know this as by then this byte
+is already tokenized. Another example is multibyte translation, for instance
+\UTF\ sequences can get remapped to something that is known internally as being a
+character of some kind. The \LUATEX\ engine expects \UTF\ so a macro package has
+to make sure that translation to this encoding happens beforehand, for instance
+using a callback that intercepts the input from file. \footnote {In \CONTEXT\ we
+talk of input regimes and these can be mixed, although in practice most users
+will stick to \UTF\ and never use regimes.}
+
+So, the input character (sequence) becomes tokens representing a character. From
+these tokens \TEX\ will start building a (linked) node list where each character
+becomes a node. In this node there is a reference to the current font. If you
+know \TEX\ you will understand that a list can have more than characters: there
+can be skips, kerns, rules, references to images, boxes, etc.
+
+At some point \TEX\ will handle this list over to a routine that will turn them
+into something that resembles a paragraph or otherwise snippet of text. In that
+stage hyphenation kicks in, ligatures get built and kerning is added. Character
+references become glyph indices. This list can finally be broken into lines.
+
+It is no secret that \TEX\ can box and unbox material and that after unboxing
+some new formatting has to happen. The traditional engine has some optimizations
+that demand a partial reconstruction of the original list but in \LUATEX\ we
+removed this kind of optimization so there the process is somewhat simpler. We
+will see more of that later.
+
+When \TEX\ ships out a page, the backend will load the real font data and merge
+that into the final output. It will now take the glyph index and build the right
+data structures and references to the real font. As a font gets subset only the
+used glyphs end up in the final output.
+
+There is one tricky aspect involved here: re|-|encoding. In so called map files
+one can map a specific metric filename onto a real font name. One can also
+specify an encoding vector that tells what a given index really refers to. This
+makes it possible to use fonts that have more than 256 glyphs and refer to any of
+them. This is also the trick that makes it possible to use \TRUETYPE\ fonts in
+\PDFTEX: the backend code filters the right glyphs from the font, remapping
+\TEX's glyph indices onto real entries in the font happens via the encoding
+vector. In \in {figure} [fig:tfm-bytes] we show a possible route for input byte
+68.

+As \LUATEX\ carries much of the bagage of older engines, you can still do it this
+way but in \CONTEXT\ \MKIV\ we have made our live much simpler: we use unicode as

+There is of course still some work to do for the backend, like subsetting, but
+the nasty dependency on the input encoding, font encoding (that itself relates to
+hyphenation) and backend re|-|encoding is gone. But keep in mind that the
+internal data structure of the font is still quite traditional.
+
+Before we move on to font formats I like to point out that there is no space in
+\TEX. Spaces in the input are converted into glue, either or not with some
+stretch and|/|or shrink. This also means that accessing character 32 in
+traditional \TEX\ will not end up as space in the output.
+
+\stopsection
+
+\startsection[title=\TEX\ metrics]
+
+\appendixdata{\in[fontdata:tfm]}
+\appendixdata{\in[fontdata:vf]}
+
+Traditional font metrics are packaged in a binary format. Due to the limitations
+of that time a font has at most 256 characters. In books dedicated to \TEX\ you
+will often find tables that show what glyphs are in a font, so we will not repeat
+that here as after all we got rid of that limitation in \LUATEX.
+
+Because 256 is not that much, especially when you mix many scripts and need lots
+of symbols from the same font, there are quite some encodings used in traditional
+\TEX, like \type {texnansi}, \type {ec} and \type {qx}. When you use \LUATEX\
+exclusively you can do with way less font files. This is easier for users,
+especially because most of those files were never used anyway. It's interesting
+to notice that some of the encodings contain symbols that are never used or used
+only once in a document, like the copyright or registered symbols. They are often
+accessed by symbolic names and therefore easily could have been omitted and
+collected in a dedicated symbol font thereby freeing slots for more useful
+characters anyway. The lack of coverage is probably one of the reasons why new
+encodings kept popping up. In the next table you see how many files are involved
+in Latin Modern which comes in a couple of design sizes. \footnote {The original
+Computer Modern fonts have \METAFONT\ source files and (runtime) generated bitmap
+files in whatever resolutions are needed for previewing and printing. The
+\TYPEONE\ follow|-|up came in several sets, organized by language support. The
+Latin Modern fonts have a few more weights and variants than Computer Modern.}

+
+A \TFM\ file can contain so called italic corrections. This is an additional kern
+that can be added after a character in order to get better spacing between an
+italic shape and an upright one. As this is manual work, it's a not that advanced
+mechanism, but in addition to width, height, depth, kerns and ligatures it is
+nevertheless a useful piece of information. But, it's a rather \TEX\ specific
+quantity.
+
+Since \TEX\ showed up many fonts have been added. In addition support for
+commercial fonts was provided. In fact, for that to happen, one only needs
+accompanying metric files for \TEX\ itself and map files and encoding vectors
+for the backend. Because a metric file also has some general information, like
+spacing (including stretch and shrink), the ex|-|height and em|-|width, this
+means that sometimes guesses must be made when the original font does not come
+with such parameters.
+
+At some point virtual fonts were introduced. In a virtual font a \TFM\ file has
+an accompanying \VF\ file. In that file each glyph has a specification that tells
+where to find the real glyph. It is even possible to construct glyphs from other
+glyphs. In traditional \TEX\ this only concerns the backend, which in \PDFTEX\ is
+built in. In \LUATEX\ this mechanism is integrated into the frontend which means
+that users can construct such virtual fonts themselves. We will see more of that
+later, but for now it's enough to know that when we talk about the representation
+of font (the \TFM\ table) in \LUATEX, this includes virtual functionality.
+
+An important limitation of \TFM\ files cq.\ traditional \TEX\ is that the number
+of depths and heights is limited to 16 each. Although this results in somewhat
+inaccurate dimensions in practice this gets unnoticed, if only because many
+designs have some consistency in this. On the other hand, it is a limitation when
+we start thinking of accents or even multiple accents which lead to many more
+distinctive heights and depths.
+
+Concerning ligatures we can remark that there are quite some substitutions
+possible although in practice only the multiple to one replacement has been used.
+
+Some fonts that are used in \TEX\ started out as bitmaps but rather soon
+\TYPEONE\ outline fonts became the fashion. These are supported using the map
+files that we will discuss later. First we look into \TYPEONE\ fonts.
+
+\stopsection
+
+\startsection[title=\TYPEONE]
+
+\appendixdata{\in[fontdata:afm]}
+\appendixdata{\in[fontdata:enc]}
+\appendixdata{\in[fontdata:map]}
+
+For a long time \TYPEONE\ fonts have dominated the scene. These are \POSTSCRIPT\
+fonts that can have more that 256 glyphs in the file that defines the shapes, but
+only 256 of them can be used at one time. Of course there can be multiple subsets
+active in one document.
+
+In traditional \TEX\ a \TYPEONE\ font is used by making a \TFM\ file from a so
+called Adobe metric file (\AFM) that come with such a font. There are several
+tool chains for doing this and \CONTEXT\ \MKII\ ships with one that can be of
+help when you need to support commercial fonts. Projects like the Latin Modern
+Fonts and \TEX\ Gyre have normalized a whole lot of fonts that came in several
+more or less complete encodings into a consistent package of \TYPEONE\ fonts.
+This already simplified live a lot but still users had to choose a suitable input
+and font encoding for their language and|/|or script. As \TEX\ only cares about
+metrics and not about the rendering, it doesn't consider \TYPEONE\ fonts as
+something special. Also, as \TEX\ and \POSTSCRIPT\ were developed about the same
+time support for \TYPEONE\ fonts is rather present in \TEX\ distributions.
+
+You can still follow this route but for \CONTEXT\ \MKIV\ this is no longer the
+recommended way because there we have changed the whole subsystem to use
+\UNICODE. As a result we no longer use \TFM\ files derived from \AFM\ files, but
+directly interpret the \AFM\ data. This not only removes the 256 limitation, but
+also brings more resolution in height and depth as we no longer have at most 16
+alternatives. There can also be more kerns. Of course we need some heuristics to
+determine for instance the spacing but that is not different from former times.
+
+Because most \TEX\ users don't use commercial fonts, they will not notice that
+\CONTEXT\ \MKIV\ treats \TYPEONE\ fonts this way. One reason is that the free
+fonts also come as wide fonts in \OPENTYPE\ format and whenever possible
+\CONTEXT\ prefers \OPENTYPE\ over \TYPEONE\ over \TFM.
+
+In the beginning \LUATEX\ only could load a \TFM\ file, which is why loading
+\AFM\ files is implemented in \LUA. Later, when the \OPENTYPE\ loaded was added,
+loading \PFB\ and \AFM\ files also became possible but it's slower and we see no
+reason to rewrite the current code in \CONTEXT. We also do a couple of extra
+things when loading such a file. As more \TYPEONE\ fonts move on to \OPENTYPE\ we
+don't expect that much usage anyway.
+
+\stopsection
+
+\startsection[title=\OPENTYPE]
+
+\appendixdata{\in[fontdata:otf]}
+
+When an engine can deal with \UNICODE\ directly it also means that internally it
+uses pretty large numbers for storing characters and glyph indices. The first
+\TEX\ descendent that went wide was \OMEGA, later replaced by \ALEPH. However, this
+engine never took off and still used its own extended \TFM\ format: \OFM. In fact,
+as \LUATEX\ uses some of the \ALEPH\ code, it can also use these extended metric
+files but I don't think that there are any useful fonts around so we can forget
+about this.
+
+We use the term \OPENTYPE\ for a couple of font formats that share the same
+principles: \OPENTYPE\ (\OTF), \TRUETYPE\ (\TTF) and \TRUETYPE\ containers
+(\TTC). The \LUATEX\ font reader presents them in a similar format. In the case
+of a \TRUETYPE\ container, one does not load the whole font but selects an
+instance from it. Internally an \OPENTYPE\ font can have the glyphs organized in
+subfonts.
+
+The first \TEX\ descendent to really go wide from front to back is \XETEX. This
+engine can use \OPENTYPE\ fonts directly and for a whole category of users this
+opened up a new world. Hoever, it is still mostly a traditional engine. The
+transition from characters to glyphs is accomplished by external libraries, while
+in \LUATEX\ we code in \LUA. This has the disadvantage that it is slower
+(although that depends on the job) but the advantage is that we have much more
+control and can extend the font handler as we like.
+
+An \OPENTYPE\ font is much more complex than a \TYPEONE\ one. Unless it is a
+quick and dirty converted existing font, it will have more glyphs to start with.
+Quite likely it will have kerns and ligatures too and of course there are
+dimensions. However, there is no concept of a depth and height. These need to be
+deduced from the bounding box instead. There is an advance width. This means that
+we can start right away using such fonts if we map those properties onto the
+\TFM\ table that \LUATEX\ expects.
+
+But there is more, take ligatures. In a traditional font the sequence \type {ffi}
+always becomes a ligature, given that the font has such a glyph. In \LUATEX\
+there is a way to disable this mechanism, which is sometimes handy when dealing
+with mono|-|spaced fonts in verbatim. It's pretty hard to disable that. For
+instance one option is to insert kerns manually. In an \OPENTYPE\ font ligatures
+are collected in a so called feature. There can be many such features and even
+kerning is a feature. Other examples are old style numerals, fractions,
+superiors, inferiors, historic ligatures and stylistic alternates.

+\stoptabulate
+
+To this all you need to add that features operate in two dimensions: languages
+and scripts. This means that when ligatures are enabled for Dutch the \type {ij}
+sequence becomes a single glyph but for German it gets mapped onto two glyphs.
+And, to make it even more complex, a substitution can depend on circumstances,
+which means that for Dutch \type {fijn} becomes \type {f ij n} but \type {fiets}
+becomes \type {fi ets}. It will be no surprise that not all \OPENTYPE\ fonts come
+with a complete and rich repertoire of rules. To make things worse, there can be
+rules that turn \type {1/2} into one glyph, or transfer the numbers into superior
+and inferior alternatives, but leaves us with an unacceptable rendered \type
+{1/a}, given that the \type {frac} features is enabled. It looks like features
+like this are to be applied to a manually selected range of characters.
+
+The fact that an \OPENTYPE\ font can contain many features and rules to apply
+them makes it possible to typeset scripts like Arabic. And this is where it gets
+vague. A generic \OPENTYPE\ sub|-|engine can do clever things using these rules,
+but if you read the specification for some scripts additional intelligence has to
+be provided by the typesetting engine.
+
+While users no longer have to care about encodings, map files and back|-|end
+issues, they do have to carry knowledge about the possibilities and limitations
+of features. Even worse, he or she needs to be aware that fonts can have bugs.
+Also, as font vendors have no tradition of providing updates this is something
+that we might need to take care of ourselves by tweaking the engine.
+
+One of the problems with the transition from \TYPEONE\ to \OPENTYPE\ is that font
+designers can take an existing design and start from that basic repertoire of
+shapes. If such a design had oldstyle figures only, there is a good chance that
+this will be the case in the \OPENTYPE\ variant too. However, such a default
+interferes with the fact that the \type {onum} feature is one that we explicitly
+have to enable. This means that writing a generic style where a font is later
+plugged in becomes somewhat messy if it assumes that features need to be turned
+on.
+
+\TEX\ users expect more control, which means that in practice just an \OPENTYPE\
+engine is not enough, but for the average font the \TEX\ model using the
+traditional approach still is quite acceptable. After all, not all users use
+complex scripts or need advanced features. And, in practice most readers don't
+notice the difference anyway.
+
+\stopsection
+
+\startsection[title=\LUA]
+
+\appendixdata{\in[fontdata:lua]}
+
+As mentioned support for virtual fonts is built into \LUATEX\ and loading the so
+called \VF\ files happens when needed. However, that concerns traditional fonts
+that we already covered. In \CONTEXT\ we do use the virtual font mechanism for
+creating missing glyphs out of existing ones or add fallbacks when this is not
+possible. But this is not related to some kind of font format.
+
+In 2010 and 2011 the first public \OPENTYPE\ math fonts showed up that replace
+their \TYPEONE\ originals. In \CONTEXT\ we already went forward and created
+virtual \UNICODE\ fonts out of traditional fonts. Of course eventually the
+defaults will change to the \OPENTYPE\ alternatives. The specification for such a
+virtual font is given in \LUA\ tables and therefore you can consider \LUA\ to be
+a font format as well. In \CONTEXT\ such fonts can be defined in so called
+goodies files. As we use these files for much more tuning, we come back to that
+in a later chapter. In a virtual font you can mix real \TYPEONE\ fonts and real
+\OPENTYPE\ fonts using whatever metrics suit best.
+
+An extreme example is the virtual \UNICODE\ Punk font. This font is defined in
+the \METAPOST\ language (derived from Don Knuths \METAFONT\ sources) where each
+glyph is one graphic. Normally we get \POSTSCRIPT, but in \LUATEX\ we can also
+get output in a comparable \LUA\ table. That output is converted to \PDF\
+literals that become part of the virtual font definitions and these eventually
+end up in the \PDF\ page stream. So, at the \TEX\ end we have regular (virtual)
+characters and all \TEX\ needs is their dimensions, but in the \PDF\ each glyph
+is shown using drawing operations. Of course the now available \OPENTYPE\ variant
+is more efficient, but it demonstrates the possibilities.
+
+\stopsection
+
+\startsection[title=Files]
+
+We summarize these formats in the following table where we explain what the file
+suffixes stand for:
+
+\starttabulate[|Tl|p|]
+\HL
+\NC tfm \NC This is the traditional \TEX\ font metric file format and it reflects

+\NC vf  \NC This file contains information about how to construct and where to

+\NC pk  \NC This is the bitmap format used for the first generation of \TEX\
+            fonts but the typesetter never deals with them. Bitmap files are more

+\HL
+\NC ofm \NC This is the \OMEGA\ variant of the \type {tfm} files that caters for
+            larger fonts. \NC \NR
+\NC ovf \NC This is the \OMEGA\ variant of the \type {vf}. \NC \NR
+\HL
+\NC pfb \NC In this file we find the glyph data (outlines) and some basic
+            information about the font, like name|-|to|-|index mappings. A

+            \NR
+\NC afm \NC This file accompanies the \type {pfb} file and provides additional
+            metrics, kerns and information about ligatures. A binary variant of
+            this is the \PFA\ format. For \MSWINDOWS\ there is a variant that has the
+            \type {pfm} suffix. \NC \NR
+\NC map \NC The backend will consult this file for mapping metric file names onto

+\NC enc \NC The backend will include (and use) this encoding vector to map
+            internal indices to font indices using glyph names, if needed. \NC
+            \NR
+\HL
+\NC otf \NC This binary format describes not only the font in terms of metrics,
+            features and properties but also contains the shapes. \NC \NR
+\NC ttf \NC This is the \MICROSOFT\ variant of \OPENTYPE. \NC \NR
+\NC ttc \NC This is the \MICROSOFT\ container format that combines multiple fonts
+            in one. \NC \NR
+\HL
+\NC fea \NC A (\FONTFORGE) feature definition file. Such a file can be loaded and
+            applied to a font. This is no longer supported in \CONTEXT\ as we have
+            other means to achieve the same goals. \NC \NR
+\NC cid \NC A glyph index (name) to \UNICODE\ mapping file that is referenced
+            from an \OPENTYPE\ font and is shared between fonts. \NC \NR
+\HL
+\NC lfg \NC These are \CONTEXT\ specific \LUA\ font goodie files providing
+            additional information. \NC \NR
+\HL
+\stoptabulate
+
+If you look at how files are organized in a \TEX\ distribution, you will notice
+that these files all get their own place. Therefore adding a \TYPEONE\ font to
+the distribution is not that trivial if you want to avoid clashes. Also, files
+are simply not found when they are not in the right spot. Just to mention a few
+paths:
+
+\starttyping
+<root>/fonts/tfm/vendor/typeface
+<root>/fonts/vf/vendor/typeface
+<root>/fonts/type1/vendor/typeface
+<root>/fonts/truetype/vendor/typeface
+<root>/fonts/opentype/vendor/typeface
+<root>/fonts/fea
+<root>/fonts/cid
+<root>/fonts/dvips/enc
+<root>/fonts/dvips/map
+\stoptyping
+
+There can be multiple roots and the right locations are specified in a
+configuration file. Currently all engines can use the \DVIPS\ encoding and map
+files, so luckily we don't need to duplicate this. For some reason \TRUETYPE\ and
+\OPENTYPE\ fonts have different locations and you need to be aware of the fact
+that some fonts come in both formats (just to confuse users) so you might end up
+with conflicts.
+
+In \CONTEXT\ we try to make live somewhat easier by also supporting a simple path
+structure:
+
+\starttyping
+<root>/fonts/data/vendor/typeface
+\stoptyping
+
+This way files are kept together and installing commercial fonts is less complex
+and error prone. Also, in practice we only have one set of files now: one of the
+other \OPENTYPE\ formats.
+
+If you want to see the difference between a traditional (\PDFTEX\ or \XETEX\ plus
+\CONTEXT\ \MKII) setup or a modern one (\LUATEX\ with \CONTEXT\ \MKIV) you can
+install the \CONTEXT\ suite (formerly known as minimals). If you explicitly
+choose for a \LUATEX\ only setup, you will notice that far less files get
+installed.
+
+\stopsection
+
+\startsection[title=Text]
+
+This is not an in|-|depth explanation of how to define and load fonts in
+\CONTEXT. First of all this is covered in other manuals, but more important is
+that we assume that the reader is already familiar with the way \CONTEXT\ deals
+with fonts. Therefore we limit ourselves to some remarks and expand on this a bit
+in later chapters.
+
+The font subsystem has evolved over years and when you look at the low level code
+you will probably find it complex. This is true, although in some aspects it is
+not as complex as in \MKII\ where we also had to deal with encodings due to the
+eight bit limitations. In fact, setting up fonts is easier due the fact that we
+have less files to deal with.
+
+The main properties of a (modern) font subsystem for typesetting text are the
+following:
+
+\startitemize[n]
+    \startitem
+        We need to be able to switch the look and feel efficiently and
+        consistently, for instance going from regular to bold or italic. So,
+        when we load a font family we not only load one file, but often
+        at least four: regular, bold, italic (oblique) and bolditalic
+        (boldoblique).
+    \stopitem
+    \startitem
+        When we change the size we also need to make sure that these related
+        sets are changed accordingly. You really want the bold shapes to scale
+        along with the regular ones.
+    \stopitem
+    \startitem
+        Shapes are organized in serif, sans serif, mono spaced and math and for
+        proper working of a typesetter that has math all over you need always
+        need the math. Again, when you change size, all these shapes need to
+        scale in sync.
+    \stopitem
+    \startitem
+        In one document several families can be combined so the subsystem should
+        make it possible to switch from one to the other without too much
+        overhead.
+    \stopitem
+    \startitem
+       Because section heads and other structural elements have their own sizes
+       there has to be a consistent way to deal with that. It should also be
+       possible to specify exceptions for them.
+   \stopitem
+\stopitemize
+
+In the next chapters we will cover some details, for instance font features. You
+can actually control these when setting up a body font, simply by redefining
+the \type {default} feature set, but not all features are dealt with this way.
+So let's continue the demands put on a font subsystem.
+
+\startitemize[continue]
+    \startitem
+        Sometimes inter|-|character kerning is needed. In \CONTEXT\ this is not a
+        property of a font because glyphs can be mixed with basically anything.
+        This kind of features is applied independent of a font.
+    \stopitem
+    \startitem
+        The same is true for casing (like uppercasing and such) which is not
+        related to a font but applied to a selected (or marked) piece of the
+        input stream.
+    \stopitem
+    \startitem
+        Using so called \quotation {small caps} or \quotation {old style}
+        numerals or \unknown\ can be dealt with by setting the default features
+        but often these are applied selectively. As these are applied using the
+        information in a font they do belong to the font subsystem but in
+        practice they can be seen as independent (assuming that the font supports
+        them at all).
+    \stopitem
+    \startitem
+        Protrusion (into margins) and expansion (to improve whitespace) are
+        applied to the font at load time because the engine needs to know about
+        them. But they two can selectively be turned on and off. They are more
+        related to line break handling than font defining.
+    \stopitem
+    \startitem
+        Slanting (to fake oblique) and expanding (to fake bold) are regular
+        features but are applied to the font because the engine needs to know
+        about them. They permanently influence the shape.
+    \stopitem
+\stopitemize
+
+We will discuss these in this manual too. What we will not discuss in depth is
+spacing, even when it depends on the (main body) font size. These use properties
+of fonts (like the ex|-|height or em|-|width and maybe the width of the space,
+but normally they are controlled by the spacing subsystem. We will however
+mention some rather specific possibilities:
+
+\startitemize[continue]
+    \startitem
+        The \CONTEXT\ font subsystem provides ways to combine multiple fonts
+        into one.
+    \stopitem
+    \startitem
+        You can construct artificial fonts, using existing fonts or \METAPOST\
+        graphics.
+    \stopitem
+    \startitem
+        Fonts can be fixed (dimensions) and completed (for instance accented
+        characters) when loading/
+    \stopitem
+    \startitem
+        There are extensive tracing options, not only for applied features but
+        also for loading, checking etc. There is a set of styles that can be
+        used to study fonts.
+    \stopitem
+\stopitemize
+
+Sometimes users ask for very special trickery and it no surprise then that some
+of that is now widely know (or even discussed in detail). When we get notice of
+that we can mention it in this manual.
+
+So how does this all relate to font formats? We mentioned that when loading we
+basically load some four files per family (and more if we use specific fonts for
+titling). These files just provide the data: metric information, shapes and ways
+to remap characters (or sequences) into glyphs, either of not positioned relative
+to each other. In traditional \TEX\ only dimensions, kerns and ligatures
+mattered, but in nowadays we also deal with specific \OPENTYPE\ features. But
+still, as you can deduce from the above, this is only part of the story. You need
+a complete and properly integrated system. It is no big deal to set up some
+environment that uses font files to achieve some typesetting goal, but to provide
+users with some consistent and extensible system is a bit more work.
+
+There are basically three font formats: good old bitmaps, \TYPEONE\ and
+\OPENTYPE. All need to be supported and expectations are that we also support
+their features. But is should be noticed that whatever font you use, the quality
+of the outcome depends on what information the font can provide. We can improve
+processing but are often stuck with the font. There are many thousands of
+fonts out there and we need to be able to use them all.
+
+\stopsection
+
+\startsection[title=Math]
+
+In the previous section we already mentioned math fonts. The fonts are just one
+aspect of typesetting math and math fonts are special in the sense that they have
+to provide the relevant information. For instance a parenthesis comes in several
+sizes and at some point turns in a symbol made out of pieces (like a top curve,
+middle lines and bottom curve) that overlap. The user never sees such details. In
+fact, there are ot that many math fonts and these are already set up so there is
+not much to mess up here. Nevertheless we mention:
+
+\startitemize [n]
+    \startitem
+        Math fonts are loaded in three sizes: text, script and scriptscript. The
+        optimal relative sizes ar defined in the font.
+    \stopitem
+    \startitem
+        There are direction aware math fonts and we support this in \CONTEXT.
+    \stopitem
+    \startitem
+        Bold math is in fact a bolder version of a regular math font (that can
+        have bold symbols too). Again this is supported.
+    \stopitem
+\stopitemize
+
+The way math is dealt with in \CONTEXT\ is different from the way it is done
+traditionally. Already when we started with \MKIV\ we moved to \UNICODE\ and
+the setup at the font level is kept simple by delegating some of the work to
+the \LUA\ end. We will see some of the mentioned aspects in more detail later.
+
+Because of it's complexity and because in a math text there can be many times
+activation of math fonts (and related settings) quite some effort has been put in
+making it efficient. But you need to keep in mind that when we discuss math
+related topics later on, this is hardly of concern. Math fonts are loaded only
+once so manipulating them a bit has no penalty. And using them later on is hardly
+related to the font subsystem.
+
+Concerning formats we can notice that traditional \TEX\ comes with math fonts
+that have properties that the engine can use. Because there were not many math
+fonts, this was no problem. The \OPENTYPE\ math fonts however are also used in
+other applications and therefore are a bit more generic. \footnote {Their
+internals are now defined in the \OPENTYPE\ specification.} For this we not only
+had to adapt the math engine in \LUATEX\ (although we kept that to the minimum)
+but we also had to think different about loading them. In later chapters we will
+see that in the transition to \UNICODE\ math fonts we implemented a mechanism for
+combining \TYPEONE\ fonts into virtual \UNICODE\ fonts. We did that because it
+made no sense to keep an old and new loader alongside.
+
+There will not be thousands of math fonts flying around. A few dozen is already a
+lot and the developers of macro packages can set them up for the users. So, in
+practice there is not much that a user needs to know about math font formats.
+
+\stopsection
+
+\startsection[title=Caching]
+
+Because fonts can be large and because we use \LUA\ tables to describe them
+a bit of effort has been put into managing them efficiently. Once converted
+to the representation that we need they get cached. You can peek into the cache
+which is someplace on your system (depending on the setup):

+
+One of the virtues of \TEX\ is its flexibility. Because we cannot predict what
+users want to mess around with, much of the underlying code has hooks. And because
+it's not too hard to add functionality that will break things we will not advocate
+all of it. Of course you can study the code and figure out what can be done and
+there is no problem with that. It's just that you shouldn't expect much support.
+
+In this chapter we collect some of these hooks. If you run into interesting ones
+that are worth mentioning, you can always ask us to add description here.

+
+Because we store font related information in \LUA\ tables there can be situations
+where the resources used outgrow memory. An example of such a font is \type
+{lastresort} that basically defined the whole \UNICODE\ range. The font is
+actually not that large as it uses similar placeholders for glyphs in a range,
+but it has rather verbose (redundant) names. As we normally don't need these, you
+can decide to strip them away.
+
+\starttyping
+\startluacode

+        name   = "remove names from lastresort",
+        action = function(fontdata)

+                for k, v in next, fontdata.descriptions do
+                    v.name = nil

+
+This will result in a much smaller font, one that has less change to crash the

+been loaded but before it gets saved.

+\startsubsection[title=Introduction]
+
+We basically have to deal with three font formats that can easily be recognized
+by the suffix of the files involved: \type {tfm} and \type {vf} files that
+describe 8 bit fonts, traditionally bitmap fonts, but as they carry only metric
+information, any 8 bit font can be described. Then there are \type {afm} files
+that contain metrics related to \TYPEONE\ fonts (stored in \type {pfb} files).
+Although such fonts could contain more than 256 shapes, the implementation was
+limited to 8 bits too. By converting \type {afm} files to \type {tfm} files,
+traditional \TEX\ can deal with \TYPEONE\ given that the backend can include them
+in the final result.
+
+In this section we will discuss some aspects of the \OPENTYPE\ font reader. As
+\TEX\ only deals with metrics (in the frontend) we need to parse them, filter
+information from it and pass the metrics to \TEX. In addition, we can use all
+kind of extra information to manipulate the so called node list but in the end
+\TEX\ is only interested in font id's (that point to a font resource) and glyph
+indexes.
+
+To overcome the 256 limitation of \TYPEONE\ fonts, in \CONTEXT\ we moved away
+from \type {tfm} files (we can of course still deal with them) and turn \type
+{afm} files into so called wide fonts. Basically we turn them in a more rich
+format that looks similar to the internal \OPENTYPE\ format we use. We will not
+go into much detail about that because \TYPEONE\ is kind of obsolete and being
+replaced by \OPENTYPE, but we will of course support the old formats simply
+because we have all these fonts around.
+
+Already early in the development of \LUATEX\ a font loader library was created
+that can turn an \OPENTYPE\ (but also a \TYPEONE) font into a \LUA\ table. This
+library is derived from \FONTFORGE\ which makes it possible to look into a font
+using that editor and at the same time get a similar view on the font in \LUA,
+which is quite handy. However, at some point in \CONTEXT\ we wanted to play with
+outlines in \METAPOST\ and for that purpose an \OPENTYPE\ reader was written in
+\LUA\ that could extract the data. Because \TYPEONE\ fonts already were done in
+\LUA\ it was a logical step to also do \OPENTYPE\ in \LUA\ so now we use an
+alternative loader that doesn't depend in the \FONTFORGE\ library. This not only
+gives more flexibility but also makes it possible to avoid some conversions
+needed to provide the \CONTEXT\ font handler with the needed information in an
+efficient way.
+
+\stopsubsection
+
+\startsubsection[title=Loading \OPENTYPE\ fonts]
+
+As with most binary media formats today an \OPENTYPE\ font file is a linked list
+of records. The top level structure is called table. There are two flavours of
+\OPENTYPE\ where the main difference is in the way the shapes are defined: they
+can be \TRUETYPE\ outlines using quadratric bezier curves or cff files using
+cubic bezier curves. The last variant is the same as \POSTSCRIPT\ \TYPEONE\
+fonts. Simplified, a quadratic curve defines the shape in points with a control
+point in between, while a quadratic one also has points but each with two control
+points (as in \METAPOST).
+
+An \OPENTYPE\ font can be large: there can be upto 65536 glyphs and lots of extra
+properties and features. In order to save space the data is rather packed using
+different numeric data types. Of course one can wonder if size really matters now
+that most bandwidth is taken by audio, video and pictures but we have to live
+with it.
+
+The definition of \OPENTYPE\ can be found on the \MICROSOFT\ website:
+\hyphenatedurl {https://www.microsoft.com/typography/otspec}. Most tables then
+could make sense for us are mentioned in the following list:
+
+\starttabulate[|Bl|l|l|]

+
+When we read these tables it depends on what we want to do with the result how
+much we will really read. For instance when we only want to identify a font and
+get some basic information we don't need to read all tables and certainly don't
+need to read them completely. If we want to have the outlines we need to read the
+\type {glyf} or \type {cff} table. If we also want to boundingbox of \POSTSCRIPT\
+shapes we even need to process the shapes so that we know the dimensions of the
+result. There is no need to summarize the format here in detail because you can
+find it on the \MICROSOFT\ site. Here I only cover some aspects that influence
+the way \TEX\ can use the fonts.
+
+One of the main differences between the readers is that the \FONTFORGE\ reader
+has a lot of (recovery) heuristics for bad fonts. Nowadays most fonts are quite
+okay, and in \CONTEXT\ we prefer to just reject bad ones. In the process of
+loading the built|-|in loader gives each glyph a name (it makes them up for
+variants needed for features). It also tries to figure out some font properties,
+like the weight. If does a pretty good job on that but it is also hard to repair
+at the \LUA\ end when it makes a bad guess. The \LUA\ variants stays closer to
+the specification, but delegates more to the final user, which is good because we
+need and want that level of control as controls is what \TEX\ is about. It also
+made it possible to support for instance colored fonts without too much effort.
+
+So what data needs to be collected? If we look at what we get eventually the list
+of glyphs is the bulk. For each glyph we collect some metric information. For
+instance we fetch the (advance) width of the glyph but also the boundingbox,
+which gives us the the height and depth.
+
+In the font file the list of glyphs starts at zero and runs up tot the total
+number of glyphs. The index in this table is used in for instance the tables that
+define the font features, for instance kerning between glyphs, or multiple glyphs
+that are turned into ligatures. Each glyph gets a name. That can be a meaningful
+one but also a rather dumb one, for instance the index number.
+
+Eventually (at least in \CONTEXT) we don't order by glyph index but by \UNICODE.
+The font file contains information about the mapping from index to \UNICODE. In
+principle other encodings are possible but we stick to \UNICODE. But, because
+many glyphs can refer to one \UNICODE\ slot, for instance a regular shape as well
+as a smallcaps or oldstyle variant. These extra glyphs we let end up in the
+private \UNICODE\ areas. This also means that with each glyph in the final table
+there is also a field that has the \UNICODE. Because we order by \UNICODE\ we
+also need to store the index. An example from a Latin Modern font is:
+
+\starttyping
+[97] = {
+    boundingbox = { 34, -10, 474, 446 },
+    index       = 28,
+    name        = "a",
+    unicode     = 97,
+    width       = 490,
+}
+\stoptyping
+
+Another example is the following. Here we end up in private space:
+
+\starttyping
+[983059] = {
+    boundingbox = { 30, -10, 734, 446 },
+    index       = 19,
+    name        = "oe.dup",
+    unicode     = 339,
+    width       = 762,
+}
+\stoptyping
+
+Yet another entry is:
+
+\starttyping
+[306] = {
+   boundingbox = { 28, -22, 790, 683 },
+   index       = 357,
+   name        = "I_J",
+   unicode     = { 73, 74 },
+   width       = 839,
+  },
+\stoptyping
+
+Here you see two \UNICODE\ numbers. That kind of information is deduced from the
+name of the glyph, using knowledge on how such names are supposed to be
+constructed, or, when that is not possible, from ligature information in the
+fonts.
+
+It makes no sense to discuss the whole font table in detail, if only because most users
+will never (need to) see it. But if your curious you can have a look at the fonts
+in the cache tree, in the \CONTEXT\ distribution from the \CONTEXT\ garden this is
+
+\starttyping
+.../tex/texmf-cache/luatex-cache/context/<somehash>/fonts/otl
+\stoptyping
+
+There can be three kind of files there, with suffixes \type {tma}, \type {tmc}
+and \type {tmb}. The first one is the table as converted from the binary font
+file. The second and third variants are just bytecode compilations of this file
+(for \LUATEX\ and|/|or \LUAJITTEX). The bytecode variants are smaller but more
+important, they load a bit faster. On my disk the largest \type{tma} file is just
+below 10 MByte (an extensive \CJK\ font) but normally they are in the few hundred
+KByte range (some are real small), with the bytecode files of course being
+relatively small to their original.
+
+However, there is a bit of cheating here. If we run the command:
+
+\starttyping
+mtxrun --script font --convert lmroman10-regular.otf
+\stoptyping
+
+A \LUA\ file is generated: \type {lmroman10-regular.lua}. This file is much larger
+than the \type {tma} file in the cache:
+
+\starttabulate[|T|T|]
+\NC 643.924 \NC lmroman10-regular.lua \NC 0.029 \NR
+\NC 209.950 \NC lmroman10-regular.tma \NC 0.010 \NR
+\NC 121.541 \NC lmroman10-regular.tmb \NC \NR
+\NC 134.564 \NC lmroman10-regular.tmc \NC 0.003 \NR
+\stoptabulate
+
+The reason for this is the following. Most information is stored in tables.
+Especially tables that describe font features can be the same all over the place.
+This is why we pack the table in a more compact format before saving it in the
+cache, and unpack it after loading. The effects on loading are neglectable but
+and it has the benefit that it saves a lot of memory. By looking at such numbers
+one should be careful with conclusions, but (assuming proper garbage collection)
+we see a memory footprint of the \type {lua} file of 2836 Kbyte, while the
+unpacked variant takes 704 Kbyte. You can imagine what happens with large \CJK\
+fonts. Loading the (larger unpacked) \type {lua} file currently costs me 0.029
+seconds, while loading and unpacking the \type {tma} file takes 0.010 seconds and
+the bytecode variant \type {tmc} 0.003 seconds.
+
+\stopsubsection
+
+\startsubsection[title=Loading \TYPEONE\ fonts]
+
+When we started with \CONTEXT\ \MKIV\ (which is shortly after we started with
+\LUATEX) the only \TFM\ files that were loaded, were those to make virtual
+\UNICODE\ math fonts, awaiting real \OPENTYPE\ math fonts. Math fonts are kind
+of special with respect to metrics and such.
+
+For \TYPEONE\ text fonts we didn't use the \TFM\ files but went for parsing \AFM\
+files. That way we could use all the glyphs provided by fonts and not be limited
+to 256 slots. So, effectively we made them \UNICODE\ and similar to \OPENTYPE. Of
+course the only features were ligatures, kerns and some special ones like \TEX\
+ligatures and replacements. With the old loader code, we always made them base
+mode fonts, which means that processing was delegated to \TEX. In the new loader
+we implement ligatures and kerns as node mode features, which means that we can
+use those fonts in base mode as well as node mode. The last options therefore
+permits to add or adapt features to \TYPEONE\ fonts as well.
+
+In the next sections we will focus on \OPENTYPE\ but as the \TYPEONE\ fonts are
+organized in a similar way, some of it also applies to this older type. The most
+important to keep in mind is that we only have \type {liga}, \type {kern} and a
+few \CONTEXT\ specific features.
+
+\stopsubsection
+
+\stopsection
+
+\startsection[title=The tables]
+
+\startsubsection[title=Structure]
+
+Getting a font read for \TEX\ happens in stages. The original \OPENTYPE\ file is
+read only once. At that moment the shapes are described in the \type
+{descriptions} subtable while by the time that we pass the information to \TEX\
+they are in \type {characters}. The reason is that we go from dimensions in font
+units to dimensions in scaled points. We start with the following table:
+
+\ctxlua{context.tocontext(fonts.tables.data.original,"original_table")}
+
+The table passed \TEX\ is constructed from this one and looks like:
+
+\ctxlua{context.tocontext(fonts.tables.data.scaled,"scaled_table")}
+
+There might be a few more (often obscure) fields for special purposes. The
+characters subtable conforms to what \TEX\ expects, while the descriptions stays
+closer to \OPENTYPE. The \type {kerns} and \type {ligatures} subtables are there
+for base mode and are not present in \type {node} mode. The \type {commands} and
+\type {fonts} subtables relate to virtual fonts.
+
+\startitemize[packed]
+\startitem
+    Start with the (already) loaded \OPENTYPE\ table.
+\stopitem

+\stopitem
+\stopitemize
+
+One of the things you need to be aware of is that all references to glyphs are
+\UNICODE\ slots, either natural ones (representing a character) or a private one
+(representing an alternative representation). In \OPENTYPE\ features are defined
+in terms of glyph indices but we prefer \UNICODE\ because that is easier to deal
+with when we run over the node list. Before font processing the character field
+in a glyph node is a \UNICODE\ slot and afterwards it's still a \UNICODE\ but
+when it's a private one it can always be resolved to a non private slot of
+sequence of slots. Of course that could also be done with indices but it's just
+more natural this way.
+
+Another thing to note is that in the descriptions we're still working with font
+units ranging from $-1000$ to $+1000$, $-2048$ to $+2048$ or similar ranges. At
+the \TEX\ end we need scaled points which are much larger numbers.
+
+The question is: how often do users need to access the raw data in a font? After
+a decade of \MKIV\ and \LUATEX\ hardly any user has requested such access,
+probably because when needed easier interfaces were provided. Also, in the
+\CONTEXT\ distrubution there are some examples of manipulations that can be
+copied and adapted to personal use. There's also a danger is messing with the
+fonts (similar messing with the node lists): you never know how it interferes
+with other (maybe future) features.
+
+If you still want to do it, best is probably to start with saving the
+to|-|be|-|passed|-|to|-|\TEX\ table in a file and have a look at it. The most
+prominent subtable is the \type {characters} table and messing a bit with
+dimensions is rather harmless. You could add characters, for instance virtual
+ones, which again is harmless unless you use invalid commands. You probably want
+to stay away from the resources subtable, if only because some of its subtables
+are shared and therefore adapting them can have side effects. The top level \type
+{shared} and \type {unscaled} subtable are off limits as is the \type
+{specification}.
+
+You can save a font by consulting one of the hashes but for a specific font
+you need to know its id. You can do this by using low level accessors but better
+is to use the helpers made for this, because they prevent saving redundant
+data.

+There are several places where you can hook in code: before scaling
+(initalizers), after scaling (manipulators) and while processing (processors).
+Only the first two are meant for tweaks.

+\starttyping

+
+A \type {initializer} is applied just before the font gets scaled. This means
+that the characterm properties and parameters are unscaled! Initializers can for
+instance be used to add extra features to fonts. You can provide an \type
+{position} key with a number to force a place in the list of initializers but of
+course you can never be sure of interference.
+
+A \type {manipulator} is applied when the font is scaled but before it gets
+passed to \TEX. It's a good place to tweak dimensions. Here you can also probide
+a \type {position}.
+
+The processors are applied when the node list gets processed, hence the \type
+{font} and optional \type {attr} arguments. The action is only applied to the
+specified font (id) and when an attribute gets passed, this is tested for a
+value. When an attribute is used, an unset attribute on the node will skip the
+action.
+
+If adapting characters and their properties is your main objetive, then there is a
+better plugin mechanism using sequencers. We illustrate this with a fake example:

+
+In between \type {before} and \type {after} we have \type {system} which is
+reserved for \CONTEXT\ actions. These actions are executed in the scaler
+function. The function get two tables passed: the original data as well as the
+target. If you ever need these hooks, you can probably best run an \type
+{inspect} on these arguments to see what you're dealing with.
+
+Fonts get reused when possible and for that a hash is calculated depending on the
+enabled features and size. If for some reason you want to adapt that hash you can
+use postprocessors. When the \type {tfmdata} table has a subtable \type
+{postprocessors}, then the actions in that subtable will be applied. When an
+action returns a string, the string will be combined with the hash. You can set
+(o rextend) the postprocessors table using the previopusly mentioned commands.
+However, in \CONTEXT\ you can best stay away from this as it might interfere. This
+mechanism is mostly provided for generic use.

+\ctxlua{context.tocontext(fonts.tables.data.goodies,"goodie_table")}
+
+Of course you will never use all the options at the same time. The best place to

+
+You sit in a cave and wonder how to keep track of your winter stock. While
+playing with some burned wood you end up with vertical strokes on the wall
+representing how much you have in store.
+
+You walk through the woods and wonder how to find your way back. Suddenly it
+strikes you that you can put markers on trees. Years from that moment the whole
+forest is marked with routes. Different symbols carry different meanings.
+
+The next thing you want to do is to carry around information and pass it onto
+following generations. So, you turn those symbols into shapes that make up the
+scripts that can be used to express your languages in.
+
+For ages scripts have evolved and the rendering of them on stone or wood and
+later paper has resulted in a multitude of coherent collections of so called
+glyphs. Manual labour turned into (semi) automated mass production and once that
+took off, developments went fast. But the quality was still somewhat dubious,
+especially when for instance specialized scripts like math had to be dealt with.
+
+Some 30 years ago Don Knuth wrote a book, and in the process invented the \TEX\
+typesetting system, the graphical language \METAFONT\ and a bunch of fonts. He
+made it open and free of charge. He was well aware that the new ideas were built
+on older ones that had evolved from common sense: how to keep track of things on
+paper.
+
+It is no surprise that an active community formed around these goodies. First of
+all the system has no strings attached: the licence is generous and there are no
+patents involved. There is also a network of user groups that takes care of
+coordinated updates to the whole machinery. Of course it helps that it all
+relates to Don Knuth.
+
+Since \TEX\ showed up several open and closed source typesetting systems have
+surfaced and only some of them survived. Also regular word processing has become
+more clever and still become better. The \TEX\ typesetting system also moved on.
+Some of its ideas have been used in other programs and some of the ideas of other
+programs made their way into \TEX. However, its main property is still there: you
+can tweak and tune it to your needs and are not hampered by too many limitations.
+
+Don Knuth had this chicken or egg problem: once you can typeset a source you need
+fonts but you can only make fonts if you can use them in a typesetting program.
+As a result \TEX\ came with its own fonts and it has special ways to deal with
+them. Given the limitations of that time \TEX\ puts some limitations on fonts and
+also expects them to have certain properties, something that is most noticeable
+in math fonts.
+
+Rather soon from the start it has been possible to use third party fonts in \TEX,
+for instance \TYPEONE. As \TEX\ only needs some information about the shapes, it
+was the backend that integrated the font resources in the final document. One of
+its descendants, \PDFTEX, had this backend built in and could do some more clever
+things with fonts in the typesetting process, like protrusion and expansion. The
+integration of front- and backend made live much easier. Another descendant,
+\XETEX\ made it possible to move on to the often large \OPENTYPE\ fonts. On the
+one hand this made live even more easy but at the other end it introduced users
+to the characteristics of such fonts and making the right choices, i.e.\ not fall
+in the trap of too fancy font usage.
+
+In this manual we will look at fonts from the perspective of yet another
+descendant, \LUATEX. It inherits the font technology from traditional \TEX, but
+also extends it so that we can deal with modern font technologies. Of course it
+offers much more, but in practice much relates to fonts one way or the other.
+
+Of course this exploration will be from the perspective of the \CONTEXT\ macro
+package but this is not a manual about how to use fonts in \CONTEXT\ as we have
+another manual for that. Much of what we say here applies to the generic font
+code as well, although some more advanced control is \CONTEXT\ specific. There is
+nothing real new here, and it all evolved from common sense and dealing with
+\TEX\ for many years. The perspective is mostly that of being a user myself so
+don't complain too loudly if things look complicated and unclear.
+
+There is some overlap between the chapters. This is because each chapter is
+written from another perspective and this document quite certainly will not be
+read as a whole but more by looking at examples.
+
+\startnotabene
+    This document will probably have an \quote {still under construction} state
+    for a long time. The functionality discussed here will stay and more might
+    show up. Of course there are errors, and they're all mine.

+\startchapter[title=Lookups][color=darkblue]
+
+\startsection[title=Introduction]
+
+In traditional \TEX\ a font is defined by referring to its filename. A
+definition looks like this:
+
+\starttyping
+\font \MyFontA = lmr10
+\font \MyFontB = lmr10 at 20pt
+\font \MyFontC = lmr10 scaled 1500
+\stoptyping
+
+The first definition defines the command \type {MyFontA} as a reference to the
+font stored in the file \type {lmx10}. No scaling takes place so the natural size
+is taken. This so called designsize is in no way standardized. Just look at these
+three specimen:
+
+\startlines
+{\definedfont[file:dejavuserif*default]Design Size (Dejavu)}
+{\definedfont[file:cambria*default]Design Size (Cambria)}
+{\definedfont[file:lmroman10-regular*default]Design Size (Latin Modern)}
+\stoplines
+
+The designsize is normally 10 point, but as there is no real reference for this a
+designer decides how to translate this into a visual representation. As a
+consequence the \type {20pt} in the second line of the example definitions only
+means that the font is scaled to (normally) twice the designsize. The third line
+scaled by a factor \type {1.5} and the reason for using a value thousand times
+larger is that \TEX's numbers are integers.
+
+The next three lines are typical for Latin Modern (derived from Computer Modern)
+because this family comes in different design sizes.
+
+\starttyping
+\font \MyFontD = lmr12
+\font \MyFontE = lmr12 at 20pt
+\font \MyFontF = lmr12 scaled 1500
+\stoptyping
+
+Because the designsize is part of the font metrics the second line (\type
+{\MyFontE}) is of similar size as \type {\MyFontB} although the 12~point variant
+is visually better suited for scaling up.
+
+These definitions refer to files, but what file? What gets loaded is the file
+with name \type {name.tfm}. Eventually for embedding in the (let's assume \PDF)
+file the outlines are taken from \type {name.pfb}. At that stage, when present, a
+\type {name.vf} is consulted in order to resolve characters that are combinations
+of others (potentially from other \type {pfb} files). The mapping from \type
+{name.tfm} to \type {name.pfb} filename happens in the so called map file. This
+means that one can also refer to another file, for instance \type {name.ttf}.
+
+All this logic is hard coded in the engine and because the virtual font mechanism
+was introduced later without extending the \type {tfm} format, it can be hard at
+times to figure out issues when a (maybe obsolete) virtual file is present (this
+can be the case if you have generated the \type {tfm} file from an \type {afm}
+file that comes with the \type {pfb} file when you buy one.
+
+But, in \LUATEX\ we no longer use traditional fonts and as a consequence we have
+more options open. Before we move on to them, we mention yet another definition:
+
+\starttyping
+\font \MyFontG = lmr12 sa 1.2
+\stoptyping
+
+This method is not part of \TEX\ but is provided by \CONTEXT, \MKII\ as well as
+\MKIV. It means as much as \quotation {scale this font to 1.2 times the
+bodyfontsize}. As this involves parsing the specification, it does not work
+as advertised here, but the next definition works okay:
+
+\starttyping
+\definefont[MyFontG][lmr12 sa 1.2]
+\stoptyping
+
+This indicates that we already had a parser for font specifications on board
+which in turn made it relatively easy to do even more parsing, for instance for
+font features as introduced in \XETEX\ and \LUATEX.
+
+\stopsection
+
+\startsection[title=Specifications]
+
+In \LUATEX\ we intercept the font loader. We do so for several reasons.
+
+\startitemize[packed]
+
+\startitem We want to make decisions on what file to load, this is needed when
+for instance there are files with the same name but different properties. \stopitem
+
+\startitem We want to be able to lookup by file, by name, and by more abstract specification.
+In doing so, we want to be as tolerant as possible. \stopitem
+
+\startitem We want to support several scaling methods, as discussed in the previous section. \stopitem
+
+\startitem We want to implement several strategies for passing features and defining non
+standard approaches. \stopitem
+
+\stopitemize
+
+The formal specification of a font is as follows:
+
+\starttyping
+\definefont[PublicReference][filename]
+\definefont[PublicReference][filename at dimension]
+\definefont[PublicReference][filename scaled number]
+\stoptyping
+
+We already had that extended to:
+
+\starttyping
+\definefont[PublicReference][filename]
+\definefont[PublicReference][filename at dimension]
+\definefont[PublicReference][filename scaled number]
+\definefont[PublicReference][filename sa number]
+\stoptyping
+
+So let's generalize that to:
+
+\starttyping
+\definefont[PublicReference][filename scaling]
+\stoptyping
+
+And in \MKIV\ we now have:
+
+\starttyping
+\definefont[PublicReference][filename*featurenames scaling]
+\definefont[PublicReference][filename:featurespecication scaling]
+\definefont[PublicReference][filename@virtualconstructor scaling]
+\stoptyping
+
+The second variant is seldom used and is only provided because some users
+have fonts defined in the \XETEX\ way. Users are advised not to use this
+method. The last method is special in the sense that it's used to define
+fonts that are constructed using the built in virtual font constructors. This
+method is for instance used for defining virtual math fonts.
+
+The first method is what we use most. It is really important not to forget the
+feature specification. A rather safe bet is \type {*default}. In a next chapter
+we will discuss the difference between these two; here we focus on the name part.
+
+The \type {filename} is in fact a symbolic name. In \CONTEXT\ we have always used
+an indirect reference to fonts. Look at this:
+
+\starttyping
+\definefont[TitleFont][SerifBold*default sa 2]
+\stoptyping
+
+A reference like \type {SerifBold} makes it possible to define styles independent
+of the chosen font family. This reference eventually gets resolved to a real
+name and there can be a chain of references.
+
+Font definitions can be grouped into a larger setup using typescripts. In that
+case, we can set the features for a regular, italic, bold and bolditalic for the
+whole set but when a fontname has a specific feature associated (as in the
+previous examples) that one takes precedence.
+
+so far we talked about fonts being files, but in practice a lookup happens by
+file as well as by name as known to the system. In the next section this will be
+explained in more detail.
+
+\stopsection
+
+\startsection[title=File]
+
+You can force a file lookup with:
+
+\starttyping
+\definefont[TitleFont][file:somefilename*default sa 2]
+\stoptyping
+
+If you use more symbolic names you can use the \type {file:} prefix in the
+mapping:
+
+\starttyping
+\definefontsynonym[SerifBold][file:somefile]
+\definefont[TitleFont][SerifBold*default sa 2]
+\stoptyping
+
+In projects that are supposed to run for a long time I always use the file based
+lookup, because filenames tend to be rather stable. Also, as the lookup happens
+in the \TEX\ directory structure, file lookups will rely on the general file
+search routines. This has the benefit that case is ignored. When no match is found
+the lookup will also use the font name database. Spaces and special characters are
+ignored.
+
+The name alone is not enough as there can be similar filenames with different
+suffixes. Therefore the lookup will happen in the order \ctxcommand {
+concatcommalist { list = fonts.readers.sequence, separator = ", ", last = " and
+", command = "type" } }. You can force a lookup by being more explicit, like:
+
+\starttyping
+\definefont[TitleFont][file:somefilename.ttf*default sa 1]
+\stoptyping
+
+\stopsection
+
+\startsection[title=Name]
+
+Say that we want to use a Dejavu font and that instead of filenames we want to
+use its given name. The best way to find out what is available is to call for a
+list:
+
+\starttyping
+mtxrun --script font --list --all dejavu
+\stoptyping
+
+This produces the following list:
+
+\startnarrowtyping

+dejavuserifbold                dejavuserifbold                dejavuserif-bold.ttf
+dejavuserifbolditalic          dejavuserifbolditalic          dejavuserif-bolditalic.ttf
+dejavuserifcondensed           dejavuserifcondensed           dejavuserifcondensed.ttf

+dejavuserifnormal              dejavuserif                    dejavuserif.ttf
+\stopnarrowtyping
+
+The first two columns mention the names that we can use to access a font. These
+are normalized names in the sense that we only kept letters and numbers. The next three
+definitions are equivalent:
+
+\starttyping
+\definefont[TitleFont][name:dejavuserif*default sa 1]
+\definefont[TitleFont][name:dejavuserifnormal*default sa 1]
+\definefont[TitleFont][name:dejavuserif.ttf*default sa 1]
+\stoptyping
+
+In the list you see two names that all point to \type {dejavusans-extralight.ttf}:
+
+\starttyping
+dejavusansextralight
+dejavusanslight
+\stoptyping
+
+There are some heuristics built into \CONTEXT\ and we do some cleanup as well.
+For instance we interpret \type {ital} as \type {italic}. In a font there is
+sometimes information about the weight and we look at those properties as well.
+Unfortunately font names (even within a collection) are often rather inconsistent
+so you still need to know what you're looking for. The more explicit you are, the
+less change of problems.
+
+\stopsection
+
+\startsection[title=Spec]
+
+There is often some logic in naming fonts but it's not robust and really depends on
+how consistent a font designer or typefoundry has been. In \CONTEXT\ we can
+access names by using a normalized scheme.
+
+\starttyping
+name-weight-style-width-variant
+\stoptyping
+
+The following values are valid:
+
+\starttabulate[|Bl|Tp|]
+\NC weight  \NC \ctxcommand { concatcommalist { list = fonts.names.knownweights  } } \NC \NR
+\NC style   \NC \ctxcommand { concatcommalist { list = fonts.names.knownstyles   } } \NC \NR
+\NC width   \NC \ctxcommand { concatcommalist { list = fonts.names.knownwidths   } } \NC \NR
+\NC variant \NC \ctxcommand { concatcommalist { list = fonts.names.knownvariants } } \NC \NR
+\stoptabulate
+
+The four specifiers are optional but the more you provide, the better the match. Let's
+give an example:
+
+\starttyping
+mtxrun --script fonts --list --spec dejavu
+\stoptyping
+
+This reports:
+
+\startnarrowtyping
+dejavuserifcondensed normal normal normal normal dejavuserifcondensed dejavuserifcondensed.ttf
+dejavuserif          normal normal normal normal dejavuserif          dejavuserif.ttf
+dejavusansmono       normal normal normal normal dejavusansmono       dejavusansmono.ttf
+dejavusanscondensed  normal normal normal normal dejavusanscondensed  dejavusanscondensed.ttf
+dejavusans           normal normal normal normal dejavusans           dejavusans.ttf
+\stopnarrowtyping
+
+We can be more specific, for instance:
+
+\starttyping
+mtxrun --script fonts --list --spec dejavu-bold
+\stoptyping
+
+\startnarrowtyping
+dejavuserif    bold normal normal normal dejavuserifbold    dejavuserif-bold.ttf
+dejavusansmono bold normal normal normal dejavusansmonobold dejavusansmono-bold.ttf
+dejavusans     bold normal normal normal dejavusansbold     dejavusans-bold.ttf
+\stopnarrowtyping
+
+We add another specifier:
+
+\starttyping
+mtxrun --script fonts --list --spec dejavu-bold-italic
+\stoptyping
+
+\startnarrowtyping
+dejavuserif    bold italic normal normal dejavuserifbolditalic     dejavuserif-bolditalic.ttf
+dejavusansmono bold italic normal normal dejavusansmonoboldoblique dejavusansmono-boldoblique.ttf
+dejavusans     bold italic normal normal dejavusansboldoblique     dejavusans-boldoblique.ttf
+\stopnarrowtyping
+
+As the first hit is used we need to be more specific with respect to the
+name, so lets do that in an example definition:
+
+\starttyping
+\definefont[TitleFont][spec:dejavuserif-bold-italic*default sa 1]
+\stoptyping
+
+Watch the prefix \type {spec}. Wolfgang Schusters \type {simplefonts} module
+nowadays uses this method to define sets of fonts based on a name only
+specification. Of course that works best if a fontset has well defined
+properties.
+
+\stopsection
+
+\startsection[title=Selectfont]
+
+The selectfont interface by Wolfgang Schuster can be used to define fonts
+by name. For a long term project workflow you probably want to use filenames
+but for average use names do well:
+
+\starttyping
+\definefontfamily [mainface] [serif] [DejaVu Serif]
+\definefontfamily [mainface] [sans]  [DejaVu Sans]
+\definefontfamily [mainface] [mono]  [DejaVu Sans Mono] [features=none]
+\definefontfamily [mainface] [math]  [Dejavu Math]
+\stoptyping
+
+This setup is triggered in the usual way:
+
+\starttyping
+\setupbodyfont[mainface]
+\stoptyping
+
+When you combine different designs you may need to apply a relative scale:
+
+\starttyping
+\definefontfamily [mainface] [math]  [XITS Math] [rscale=1.1]
+\stoptyping
+
+Some fonts come in designsizes, like Latin Modern:
+
+\starttyping
+\definefontfamily
+  [mainface]
+  [serif]
+  [Latin Modern Roman]
+  [designsize=auto]
+\stoptyping
+
+You can define fallbacks, for example:
+
+\starttyping
+\definefallbackfamily
+  [mainface]
+  [serif]
+  [DejaVu Serif]
+  [range=cyrillic]
+
+\definefontfamily [mainface] [serif] [TeX Gyre Pagella]
+\stoptyping
+
+Here Pagella is used with missing characters taken from Dejavu. The ranges
+are defined with:
+
+\starttyping
+\definefontfamilypreset
+  [range:cyrillic]
+  [range={cyrillic,
+          cyrillicextendeda,
+          cyrillicextendedb,
+          cyrillicsupplement}]
+\stoptyping

+\startsection[title=Introduction]
+
+As one can expect, math support in \CONTEXT\ is to some extend modelled after
+what plain \TEX\ provides, plus what was later decided to be standard. This
+mostly concerns the way fonts behave and what names are used to access glyphs or
+special constructs. It means that when you come from another macro package you
+can stick to coding math the way you did before, at least the basic coding. In
+addition to this, \CONTEXT\ gives control over fonts, structure and rendering and
+most of that was either driven by personal need or user demand. To be honest,
+many of the options are probably of not much interest to the average user.
+
+As we focus on fonts we will only touch this aspect of math here. Right from when
+we started with developing \LUATEX, cleaning op the math part of \CONTEXT\ was
+part of the game. Some primitives were added that would make it possible to avoid
+unnecessary complex macros to get certain glyphs rendered, like radicals, accents
+and extensibles. This was made easy because we also support \OPENTYPE\ math and
+because we knew that eventually the Latin Modern and Gyre fonts would also
+support \OPENTYPE. In order to move forward and get rid of traditional eight bit
+fonts \CONTEXT\ \MKIV\ can construct a virtual \OPENTYPE\ font from traditional
+math fonts. It makes not much sense to discuss that here as by now this method is
+only provided for reasons of compatibility and a reference to the past. As a lot
+of time went into this it will always stay around if only to remind us of what
+we went through to get where we are now.
+

+
+\startsection[title=\UNICODE\ math]
+
+Due to the limited amount of glyphs in a \TYPEONE\ font a macro package has to
+jump through loops in order to get traditional \TEX\ engines behave well. As a
+practical consequence these fonts are often a mixture of characters, symbols,
+punctuation and snippets that make up larger shapes. The font dimensions in these
+files have often special meanings too.
+
+This has all changed considerably with math being part of \UNICODE. It was however
+\MICROSOFT\ where the real action took place: the development of the first font that
+combined \UNICODE\ with \OPENTYPE\ technology. The Cambria font can be considered
+the benchmark for fonts that surfaced later. The characteristic of a math font are
+the following:
+
+\startitemize[packed]
+    \startitem All math alphabets are present: latin as well as greek, in regular,
+    italic, bold, fraktur and script variants as well as some combinations of these. \stopitem
+    \startitem The symbols that make sense are present (read: the more obscure shapes
+    can be omited). \stopitem
+    \startitem For the characters that make sense, there are two variants that render well
+    at smaller sizes: script and scriptscript. In the font they have the same size but
+    the application will scale them down. This feature is named \type {ssty}. \stopitem
+    \startitem Characters that can extend horizontally (for instance accents and arrows) or vertically
+    (like radicals and fences) have associated larger variants and carries information about
+    how to grow indefinitely. \stopitem
+    \startitem There is a whole lot of special math dimensions. Most of the ones
+    already used in \TEX\ are present. \stopitem
+    \startitem Some glyphs come in variants in order to please special usage. There
+    can also be variants for script or fraktur alphabets. \stopitem
+\stopitemize
+
+This means that in practice an \OPENTYPE\ math font is quite large. We easily
+have thousands of glyphs. It also means that creating such a font involves some
+expertise and this is one of the reasons why \TEX\ usergroups have joined forces
+in developing a suite of fonts. There are also other initiatives in the \TEX\
+community, of which Xits is an example. \footnote {This is a useable
+variant of Stix fonts with proper math features, some extra glyphs and
+experimental right||to||left shapes.} The well known Lucida Bright math font
+package has also been upgraded to a set of \OPENTYPE\ math fonts.
+
+The fact that there are not that many math fonts out there has a positive side as
+well: \CONTEXT\ comes with them pre|-|configured. Because during the development
+of \LUATEX\ we needed to have at least a couple of fonts for testing, and because
+it makes no sense to waste time on traditional fonts, the Latin Modern, Palatino,
+Times and a few more fonts were (and still are) provided as virtual \UNICODE\
+fonts.
+
+In a regular text font, what you key in is what you get out. So, when you've
+chosen a font with an italic shape, you get italic shapes, even if the smallcaps
+feature is enabled. In math, if you use the right unicodes you also get the shape
+you expect. Because in this case italic shapes are situated in one of the
+alphabets you explicitly choose a rendering. You can enter the right codepoints
+directly, so for instance if you enter \UNICODE\ character \type {U+1D434} you
+will get \mathematics {\utfchar {"1D434}}. In practice something like \type {$\bi
+A$} should also give that character if only because that is what we have been
+doing for over three decades. This means that the engine has to map a regular
+\type {A} onto the bold italic alphabet. In a traditional approach you will use
+math families for this, but in \CONTEXT\ \MKIV\ we simply use one font and one
+family and let the \MKIV\ machinery do the rest.
+
+In text mode we switch fonts styles in the following way:
+
+\startbuffer
+regular {\it italic} {\bf bold} {\bi bold italic} and so on
+\stopbuffer
+
+\typebuffer
+
+The three commands shown here are shortcuts for font switches. This input is
+converted into an internal representation and after whatever manipulations
+are applied end up as:
+
+\blank \getbuffer  \blank
+
+If we look at what fonts we end up with we get:
+
+\blank \markfonts{\getbuffer} \blank
+
+Now lets do the same in math mode:
+
+\startbuffer
+$regular {\it italic} {\bf bold} {\bi bold italic} and so on$
+\stopbuffer
+
+\typebuffer
+
+This time we get a different result:
+
+\blank \getbuffer \blank
+
+If again we analyze the fonts you see this:
+
+\blank \markfonts{\getbuffer} \blank
+
+All glyphs come from the same font. Instead of regular we get italic simply because
+math characters are italic by nature. The two character style switches are not
+really font switches but just make sure that the given input is mapped onto the
+right alphabet.
+
+A traditional approach using \TYPEONE\ fonts is to use a so called math family for
+each alphabet. In that case each alphabet maps one||to||one onto the font: when
+we switch to a bold family we just take the glyph that sits in that slot. In \MKIV\
+we have all characters in one family so behind the screens a given character is
+remapped.
+
+Now take a look at the following example:
+
+\startbuffer
+$text^{script^{scriptscript}}$
+\stopbuffer
+
+\typebuffer
+
+This renders to this, with the characters marked by font:
+
+\blank \markfonts{\getbuffer} \blank
+
+This time we have three different fonts: one for each of the three math sizes.
+But this representation is not entirely honest, because indeed we have three font
+instances for math, but the glyphs come from the same \OPENTYPE\ math font. We
+just load the same font three times, once for each size. In fact we load the
+font once, but use three copies, scaled accordingly to the relative scale the
+font prescribes.
+
+There is a whole bunch of commands to choose specific characters in math mode
+using a regular input. These are state switching commands.

+This chapter is not meant as an introduction to math but it is good to know
+that math font support in \CONTEXT\ is rather flexible. There are several
+mechanisms for remapping and converting characters and sequences into
+others and more is possible. Here is one:
+
+\startbuffer
+\startformula
+\reals {\mathbf R} \utfchar{"0211D} \utfchar{"1D411}
+\stopformula
+\stopbuffer
+
+\typebuffer \blank \getbuffer \blank
+
+Compare this to:
+
+\startbuffer
+\setupmathematics[symbolset=blackboard-to-bold]
+\startformula
+\reals {\mathbf R} \utfchar{"0211D} \utfchar{"1D411}
+\stopformula
+\stopbuffer
+
+\typebuffer \blank \start \getbuffer \stop \blank
+
+Greek is always troublesome because instead of regular text shapes math uses a
+few variants. Because in \UNICODE\ characters are only included once, we have
+gaps in the math alphabets but \MKIV\ will take care of this. \footnote {This is
+a typical example of where exceptions in a standard force all applications that
+deal with it have to implement tweaks.} Depending on the field an author has to
+choose between upright and italic greek:
+
+\startbuffer
+$\nabla \alpha \mathgreekupright \nabla \alpha \mathgreekitalic \nabla \alpha$
+\stopbuffer
+
+\typebuffer \blank \start \getbuffer \stop \blank
+
+By default \CONTEXT\ is set up as follows:
+
+\starttyping
+\setupmathematics
+  [sygreek=normal,
+   lcgreek=italic,
+   ucgreek=normal]
+\stoptyping
+
+Again, these are not features of a font. The font just provides the glyphs and
+the \TEX\ engine, controlled by \CONTEXT\ takes care of mapping characters to
+glyphs and building special constructs. The same is true for spacing. Although
+math fonts do have kerning information, most of the math spacing is controlled
+by properties of characters and not by the font.

+As a user you don't have to worry about these issues because characters are tagged
+according to their usage. \footnote {There are a few more commands, like \type
+{\mathlimop}, \type {\mathnolop} and \type {mathbox} but these are used
+differently.}
+
+With \TEX\ being the oldest and still dominant math renderer it is no surprise
+that \MICROSOFT\ modelled its math renderer after \TEX\ and Cambria quite well
+suits the concept. In retrospect it is somewhat unfortunate that we're still
+stuck with some left overs (or compromises) from the past with respect to spacing
+built into the font. However, as long as this is consistent over fonts it's not
+that relevant. You can always influence the spacing with the commands mentioned.
+
+If you look at the low level definitions in for instance plain \TEX\ but also in
+\CONTEXT\ \MKII\ that relate to prime symbols it probably takes a while before you
+figure out what happens there. For instance, the prime symbol is triggered by a
+quote and multiple in a row results in primes that are spaced tightly. In
+\UNICODE\ we have slots for single, double and tripple primes. Therefore, in
+\MKIV\ we have a mechanism that accepts different kinds of input that eventually
+all end up in one of these three glyphs.

+
+Again, this is not the same as ligature building features in text fonts, but
+handled in a different way.
+
+The \TEX\ engine understands the concept of italic correction. When an italic
+shape is followed by for instance an upright shape, you can insert a \type {\/}
+and the engine will add a correction as defined in the font. In \OPENTYPE\ we
+don't have such corrections available but we can fake it, which is what the \type
+{itlc} feature in \CONTEXT\ does. However, you need to enable this feature
+explicitly. An example of a setup is:
+
+\starttyping
+\definefontfeature
+  [default]
+  [default]
+  [itlc=yes,textitalics=yes]
+
+\setupitaliccorrection
+  [global,always]
+\stoptyping
+
+This will make sure that the right amount of correction is added between
+italic shapes and non italics or boxes. Using \type {text} instead of
+\type {always} would limit the correction to glyphs only and leaving out
+the \type {global} would permit selective (grouped) usage at the cost
+of more runtime. There is no need for the \type {\/} here.
+
+In math we also can have italic correction but there it is built into the engine
+and in traditional \TEX\ no directives are needed. Italic correction properties
+in math fonts are somewhat troublesome as their application depends on what we're
+dealing with: symbols, super- and subscripts, etc. Because early versions of
+\LUATEX\ didn't handle all of it well, if only because the fonts were not yet okay,
+the \MKIV\ math handler provides a bit of control.
+
+\def\SampleLine#1#2%

+\SampleLine4{use method 1 but fall back on 3 if needed}
+\stoptabulate
+
+Because we cannot rely on fonts too much, we default to method~3 which in practice
+works out well, so the setup is:
+
+\starttyping
+\setupmathematics
+  [italics=3]
+\stoptyping
+
+There are all kind of commands that can be used to build math constructs in such a
+way that super- and subscripts are consistently rendered. It goes beyond this
+chapter to discuss them and most users will never see or use those commands. The
+main message of the examples above is that text and math use different fonts and
+properties and therefore also different methods in rendering text or a formula.
+Even if the names of mechanisms are the same (like italics) you cannot assume
+that both modes do exactly the same.
+
+\stopsection
+
+\startsection[title=Bold math]
+
+If you look at what \UNICODE\ provides you will notice that there are quite some
+bold characters. First of all there are a bunch of alphabets and because bold is
+not present in the text part of \UNICODE\ these alphabets have no holes. Then
+there are some symbols that have special meaning.
+
+\startluacode
+local find = string.find
+local NC, NR = context.NC, context.NR
+
+context.starttabulate { "|Tl||l|" }
+for unicode, entry in table.sortedhash(characters.data) do
+    local description = entry.description
+    if find(description,"^MATHEMATICAL BOLD") then
+        NC() context("U+04X",unicode)
+        NC() context.mathematics(utf.char(unicode))
+        NC() context(description)
+        NC() NR()
+    end
+end
+context.stoptabulate()
+\stopluacode
+
+The biggest mistake one can make when discussing bold math is the assumption that
+these bold alphabets are meant for section titles and other structural elements
+that need some emphasis. This is not true, in that case we would expect the whole
+formula to be bold and the bold symbols or variables would be even more bold.
+Bold math boils down to {\em all} math being bold. The reason why we show the
+list of bold characters on the previous pages is that it gives a good impression of
+fact that we're mostly given alphabets in an otherwise regular font.
+
+As Latin Modern (being derived from Computer Modern) has some bold extras in
+\MKII\ to some extend we do support a complete bold math switch but mixing bold
+formulas with regular ones has some limitations. Math typesetting consists of two
+phases: first the input is translated into a special list where references to
+fonts are not yet resolved. Instead families are used and each family has three
+sizes: text, script and scriptscript. In a second pass the formula is typeset and
+the families get translated into fonts. So, if we change the definition of a
+family, say math italic into bold math italic, then the definition that is actual
+when the second pass takes place is used.
+
+Although \LUATEX\ provides for many more families and as a consequence we could
+have replaced the \MKII\ mechanism with a more complete one, instead we just
+forgot about it and stuck to one family for regular math and another one for bold
+math. Okay, this is not entirely true as later on we added some more in order to
+deal with bidirectional typesetting.
+
+Only a few math fonts come with a bold variant. One of the objectives of the \TEX
+Gyre math font project is to explore the possibilities of bold math companions,
+but such a font will probably have less coverage, simply because no real complex
+math will end up in for instance section titles.
+
+When I wrote this down there were not that many math fonts that come with a real
+(complete) bold variant. The \CONTEXT\ math font subsystem tries to fill this gap
+as good as possible by using pseudo fonts. When a typeface doesn't define a math
+bold variant a pseudo setup is used. When a real bold font is used, it could be
+that not all alphabets are supported in which case a suitable alternative is
+tried.
+
+The Xits font, assembed from Stix and enhanced by Khaled Hosny, comes with a bold
+variant but the coverage is not complete, at least not when I wrote this
+paragraph. This can go unnoticed because \CONTEXT\ tries to work around this. On
+the other hand, it definitely has bold properties, which can be seen from the
+next example. You switch between regular and bold math with the \type {\mr} and
+\type {\mb} commands.
+
+\startbuffer
+\switchtobodyfont[xitsbidi]
+
+$             \sqrt{x } \quad
+ \mb          \sqrt{mb} \quad

+
+You can track some of what happens with:
+
+\starttyping
+\enabletrackers[math.remapping,math.families]
+\stoptyping
+
+You will get some information about remapping or when it fails if fallback
+remapping is used. But no matter what happens with glyphs, you will notice in
+this example that the radical symbol is bold indeed.
+
+\stopsection
+
+\startsection[title=Bidirectional math]
+
+There is not that much to tell about bidirectional math typesetting, simply
+because the fonts are still in development. However, Khaled Hosny added
+some support to the Xits font. Of course you need to load this font first:
+
+\starttyping
+\switchtobodyfont[xitsbidi]
+\stoptyping
+
+In the previous chapter we mentioned bold math and as Xits also comes with
+a bold variant which means that this command loads the whole lot (which is
+fast enough anyway).
+
+Easiest is to just show a few examples. When in left to right mode we get what we
+are accustomed to:
+
+\startbuffer
+\setupmathematics[align=l2r]
+
+\startformula
+\sqrt{x^2\over 4x} \eqno(1)
+\stopformula
+

+5 < 6 > 4
+\stopformula
+
+\startformula
+5 \leq 6 \geq 7
+\stopformula
+\stopbuffer
+
+\typebuffer \start \switchtobodyfont[xitsbidi] \getbuffer \stop
+
+However, when we go the other way, we automatically get digits converted to
+arabic.
+
+\startbuffer
+\setupmathematics[align=r2l,bidi=yes]
+
+\startformula
+\sqrt{ف^2\over 4ب} \eqno(1)

+\stopformula
+
+\startformula
+5 \leq 6 \geq 7
+\stopformula
+\stopbuffer
+
+\typebuffer \start \switchtobodyfont[xitsbidi] \getbuffer \stop
+
+You don't have to worry about how the font is set up, but not that much is needed
+because \CONTEXT\ does it for you and the Xits typescripts carries the right
+definitions. Just to give you an idea, we show a feature definition: The magic is
+in the \type {rtlm} feature combined with \type {locl}.
+
+\starttyping
+\definefontfeature
+  [mathematics-r2l]
+  [mathematics]
+  [language=ara,
+   rtlm=yes,
+   locl=yes]
+\stoptyping
+
+Some symbols are mirrored too:
+
+\startbuffer

+
+\startformula
+\sum^\infty_{س=0} س^2 \eqno(2)
+\stopformula
+\stopbuffer
+
+\typebuffer \start \switchtobodyfont[xitsbidi] \getbuffer \stop
+
+And of course the extensible fences are done properly too:

+\startbuffer
+\setupmathematics[align=r2l,bidi=yes]
+
+\startformula
+\left(\root{2} \of{155}\right)
+\stopformula

+\left\{\sum^{55}_{123} 666^3\right\}
+\stopformula
+\stopbuffer
+
+\typebuffer \start \switchtobodyfont[xitsbidi] \getbuffer \stop
+
+The real torture test is the radical sign. A mirrored shape is used
+and it grows upwards as well as leftwards.
+

+
+\startformula
+\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{55}}}}}}}}}}

+
+In text mode you use font switches like \type {\sl} that switches the current font
+to a slanted one. In math mode it is an alphabet switch in the same font. In
+fact, there isn't much to choose from fonts there, apart from a massive switch
+to bold, in which case \type {\bf} is just a bolder alphabet in that bolder font.
+
+A lot of things in math mode happen automatically. There are for instance always
+three instances of (the same) font active, each different in size: text, script
+and the smallest, scriptscript and when you ask for instance for a superscript
+the next smaller size is used.
+
+\starttabulate[|l|l|l|]
+\NC normal   \NC \type {\textstyle}         \NC $\textstyle         text^{script^{scriptscript}}$ \NC \NR

+\NC smallest \NC \type {\scriptscriptstyle} \NC $\scriptscriptstyle text^{script^{scriptscript}}$ \NC \NR
+\stoptabulate
+
+In text style, superscripts can go twice smaller, but in script style only one
+smaller size is left, and in scriptscript style you're stuck with one size. The
+commands in the second column can be used to force a style.
+
+The math formula builder has an important property: the formula is typeset after
+it has been scanned completely. In a traditional setup that has some
+consequences. Take this:
+
+\starttyping
+one \sl two \bf three \bi four
+\stoptyping
+
+In a traditional setup four so called families are used and each character gets
+tagged with a family number. So we have (for instance):
+
+\blank \start \tttf
+o\low7n\low7e\low7 t\low6w\low6o\low6 t\low5h\low5r\low5e\low5e\low5 f\low9o\low9u\low9r\low9
+\stop \blank
+
+As the number of families was limited there could be at most 16 families. In
+fact, the first four were traditionally reserved for math roman, math italic,
+symbol and extensibles. Then, due to the limit of 256 characters per font,
+another few were used for additional symbol fonts. So, adding a few more variants
+could exhaust the family pool quite fast. You could argue that we could halfway
+redefine a family but this will not work as there is a one to one relationship
+between family numbers and fonts assigned to them when the formula has been
+read in (the last value counts). And grouping won't help you either.
+
+The actual (plain) situation is even more complex. As we have a limited number of
+characters per font, most symbols are accessed by name, and the name relates to a
+mathematical character definition using for instance \type {\mathchardef}. Such a
+definition refers to a slot in a specific family number and therefore font. It
+also puts a character in a so called math class. One of these, the alphanumeric
+class, with number~7, is special. Characters that are input directly on the
+keyboard (like \type {a}||\type {z} can also be tagged this way using \type
+{\mathcode}.
+
+When we switch a family, this will normally not affect a symbol defined as math
+character, simply because we refer to a specific family|/|slot combination, but
+when a character has class~7, then it will be taken from the current family. This
+permits latin letters, digits and greek letters to be typeset in different
+styles. So, in that traditional approach we have fonts that provide a bunch of
+symbols as well as some alphabets. Think for instance of a font with additional
+symbols where the regular alphabet slots contain blackboard shapes. The symbols
+are accessed directly and the characters are accessed via the regular \type
+{a}||\type {z} characters as these will adapt to the family and therefore font.
+In practice users will not notice this complication as macro packages hide the
+implementation details.
+
+In \MKIV\ the situation is different as there we have one family (or a few more
+if we use a full bold switch and|/|or bidirectional math). Although we no longer
+have the limit of 16 fonts we actually don't need that many families, at least
+not in the way we've set up \MKIV \footnote{A technical note: in principle the
+\MKIV\ approach can have a speed penalty compared to a multi||family approach but
+we don't care too much about it. Also, as we load less fonts the extra overhead gets
+compensated nicely.}
+
+\blank \start \tttf
+o\low1n\low1e\low1 t\low1w\low1o\low1 t\low1h\low1r\low1e\low1e\low1 f\low1o\low1u\low1r\low1
+\stop \blank
+
+So how does this relate to styles? Each family has three fonts and we can use the
+switch commands to choose any of these. In text mode we use the term style for a
+font switch, while in math mode it's more than that: indeed we switch a font, but
+only in size, but the spacing is also adapted. If a proper math font is used, the
+smaller sizes are actually alternates in the font, visually adapted to suit their
+use.
+
+In text mode we do this in order to limit the scope of a switch:
+
+\starttyping
+normal {\bf bold {\it italic} bold} normalbracket
+\stoptyping
+
+This is the same as:
+
+\starttyping
+normal \bgroup \bf bold \bgroup \it italic\egroup
+    \ bold\egroup \ normalbracket
+\stoptyping
+
+and:
+
+\starttyping
+normal \begingroup \bf bold \begingroup \it italic\endgroup
+    \ bold\endgroup \ normalbracket
+\stoptyping
+
+The \CONTEXT\ distribution ships with a plain math definition file that also uses
+one family but reassigns some math codes when we switch to another style. As the
+number of characters that this applies to this is efficient enough for a modern
+computer. A peek into \type {luatex-math.tex} gives an impression of what we deal
+with. However, keep in mind that the implementation in \MKIV\ goes it differently
+and is therefore more powerful. We also have hardly any definitions at the \TEX\
+end and use information from \type {char-def.lua} instead.
+
+In math mode there is a subtle difference in the way grouping works with styles:
+
+\starttyping
+text {\scriptstyle script} normal
+\stoptyping
+
+This is the same as:
+
+\starttyping
+text \bgroup\scriptstyle script\egroup\ normal
+\stoptyping
+
+but different from:
+
+\starttyping
+text \begingroup\scriptstyle script\endgroup\ script
+\stoptyping
+
+This has to do with the fact that a style switch is explicitly registered in the
+math list and grouping like this is not limiting the scope. In math mode the
+braced grouping mode actually does create a math group and there the scope of the
+switch is limited to that group. In practice users will not run into this but
+they can use macros that use \type {\begingroup}. Among other reasons, this is
+why we have a special mathstyle mechanism.
+
+\startbuffer
+\ruledhbox{$x\begingroup\scriptstyle x\endgroup x$} \quad
+\ruledhbox{$x\begingroup\setupmathstyle[script]x\endgroup x$} \quad
+\ruledhbox{$x{\setupmathstyle[script]x}x$} \quad
+\ruledhbox{$x\startmathstyle[script]x\stopmathstyle x$}
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection[blank] \dontleavehmode \getbuffer \stoplinecorrection
+
+Mechanisms that support the \type {mathstyle} parameter know how to apply the
+proper grouping so you don't have to worry there. You can best avoid using the
+verbose grouping command and stick to braces or the \type {start}||\type {stop}
+command. An example is the fence mechanism:
+
+\startbuffer
+\definemathfence
+  [fancybracket] [bracket]
+  [color=darkblue]
+\definemathfence
+  [smallbracket] [bracket]
+  [command=yes,color=darkgreen,mathstyle=small]
+\definemathfence
+  [normalbracket] [bracket]
+  [command=yes,color=darkred]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We apply this to an example:
+
+\startbuffer
+$x \fenced[bar]{\frac{1}{x}} x$ \quad
+$x \fenced[doublebar]{\frac{1}{x}} x$ \quad
+$x \fenced[bracket]{\frac{1}{x}} x$ \quad
+$x \fenced[fancybracket]{\frac{1}{x}} x$ \quad
+$x \frac{1}{n} \normalbracket{\frac{1}{n}} \smallbracket{\frac{1}{s}} x$
+\stopbuffer
+
+\typebuffer
+
+Of course these somewhat weird examples are not real but at least they
+demonstrate the principles.
+
+\startlinecorrection[blank] \dontleavehmode \getbuffer \stoplinecorrection
+
+A math style is a combination of the following keys. Their effect can depend on
+the current state, for instance you can switch cramp or size indepently.
+
+\starttabulate[|T||]
+\NC display          \NC display style, like text style but somewhat more spacy \NC \NR
+\NC text             \NC text style, normally used inline \NC \NR
+\NC script           \NC smaller than text cq. display style \NC \NR
+\NC scriptscript     \NC smaller than script style \NC \NR
+\NC cramped packed   \NC more tightly positioned superscripts \NC \NR
+\NC uncramped normal \NC normal positioned superscripts \NC \NR
+\NC small            \NC switch to the next smaller style but keep cramp state \NC \NR
+\NC big              \NC switch to the next larger style but keep cramp state \NC \NR
+\stoptabulate
+
+Future versions of \MKIV\ will provide more features (like parameter sets driven
+by keywords). As you might prefer a more symbolic approach we provide:
+
+\starttyping
+\definemathstyle[default][text,cramped]
+\stoptyping
+
+After this you can use the keyword \type {default} which has the advantage that
+you only need to change one definition in order to get different rendering.
+
+\stopsection
+
+\startsection[title=Supported fonts]
+
+As in \CONTEXT\ MKIV\ I wanted to go ahead with \UNICODE\ math as soon as the
+first version of \LUATEX\ showed up. Because at that time only Cambria was
+available I decided to provide virtual \UNICODE\ math fonts as a prelude to
+proper replacements for the popular \TYPEONE\ math fonts. In the meantime Xits
+came around and in 2012 we had quite useable math companions for the public Latin
+Modern, Pagella and Termes fonts and the \TEX\ user groups started shipping
+\OPENTYPE\ variants of Lucida. The virtual variants will still around so that we
+can compare them with the new implementations. As the official specification of
+\OPENTYPE\ math is not always clear from the beginning the \OPENTYPE\ fonts get
+improved over time. In fact, this is true not only for math fonts. Just think of
+this:
+
+\startitemize
+
+\startitem As \UNICODE\ gets extended, fonts might get more glyphs and possibly
+alternate shapes. \stopitem
+
+\startitem The more languages are supported, the more glyphs are to be available
+and features have to get language dependent instances. \stopitem
+
+\startitem The larger the font, the bigger the chance that mistakes get unnoticed
+especially when contextual subtitutions and positioning are used. \stopitem
+
+\startitem Math fonts can get more script and scriptscript alternates, more size
+variants, more advanced extensibles, bidirectional support, etc. \stopitem
+
+\stopitemize
+
+So, like regular programs, \LUATEX\ and macro packages, we now have fonts as
+component that needs occasional updating. Of course resources like hyphenation
+patterns are also subjected to this, so it's not a new aspect. But still, best
+keep en eye on font updates.
+
+While there are lots of text fonts, there are not that many math fonts, so you
+can safely assume that \CONTEXT\ ships with the proper setup for those fonts. Of
+course you have to choose a specific instance when you set up your own
+combination of fonts, but a peek into the typescripts shows the way.
+
+In the font manual and on the wiki you can find more about typescript and what is
+possible, so here we just take a look at one definition:
+
+\startnarrowtyping
+\starttypescript [serif] [dejavu] [name]
+  \definefontsynonym [Serif]           [name:dejavuserif]           [features=default]
+  \definefontsynonym [SerifBold]       [name:dejavuserifbold]       [features=default]
+  \definefontsynonym [SerifItalic]     [name:dejavuserifitalic]     [features=default]
+  \definefontsynonym [SerifBoldItalic] [name:dejavuserifbolditalic] [features=default]
+\stoptypescript
+
+\starttypescript [sans] [dejavu] [name]
+  \definefontsynonym [Sans]           [name:dejavusans]            [features=default]
+  \definefontsynonym [SansBold]       [name:dejavusansbold]        [features=default]
+  \definefontsynonym [SansItalic]     [name:dejavusansoblique]     [features=default]
+  \definefontsynonym [SansBoldItalic] [name:dejavusansboldoblique] [features=default]
+\stoptypescript
+
+\starttypescript [mono] [dejavu] [name]
+  \definefontsynonym [Mono]           [name:dejavusansmono]            [features=none]
+  \definefontsynonym [MonoBold]       [name:dejavusansmonobold]        [features=none]
+  \definefontsynonym [MonoItalic]     [name:dejavusansmonooblique]     [features=none]
+  \definefontsynonym [MonoBoldItalic] [name:dejavusansmonoboldoblique] [features=none]
+\stoptypescript
+
+\starttypescript[dejavu]
+  \definetypeface [dejavu] [rm] [serif] [dejavu] [default]
+  \definetypeface [dejavu] [ss] [sans]  [dejavu] [default]
+  \definetypeface [dejavu] [tt] [mono]  [dejavu] [default]
+  \definetypeface [dejavu] [mm] [math]  [xits]   [default] [scale=1.2]
+\stoptypescript
+\stopnarrowtyping
+
+So, in many cases you can just copy this blob and replace the font names by your
+own.
+
+Loading a font, and Dejavu is a predefined one, is done as follows:
+
+\starttyping
+\setupbodyfont[dejavu]
+\stoptyping
+
+In a similar fashion you can enable \type {cambria}, \type {pagella}, \type
+{termes}, \type {lucidaot}, etc.\ and if you don't use this command at all, you
+get Latin Modern. These fonts are part of \TEX\ distributions, including
+\CONTEXT\ stand||alone that can be downloaded from \CONTEXT\ garden.
+
+If you want to use Lucida, all you have to do when you have bought the fonts, is
+to put the \OPENTYPE\ files in a place where they can be found, for instance:
+
+\starttyping
+tex/texmf-fonts/fonts/data/lucida
+\stoptyping
+
+Of course you need to run \type {mtxrun --generate} afterwards so that the files
+can be found.
+
+\startnotabene
+    Tracing and characters coverage will be discussed here as soon as the styles
+    that are used for them are normalized.
+\stopnotabene
+
+\stopsection
+
+\startsection[title={Stylistic alternates}]
+
+Some fonts provide stylistic alternates. These can be described in goodies files
+and the Lucida setup is a good example. Here we demonstrate the effects. We
+disable the default math rendering (which takes the italic variants).
+
+\startbuffer[sa:1]
+\switchtobodyfont[lucidaot,14.4pt]
+\setupmathrendering[lucidaot][it=]
+$x
+   ^{i \leftarrow 0 = ∅}
+   _{i \leftarrow 0 = ∅}
+$
+\stopbuffer
+
+\typebuffer[sa:1]
+
+The next code enabled three alternatives:
+
+\startbuffer[sa:2]
+\switchtobodyfont[lucidaot,14.4pt]
+\setupmathrendering[lucidaot][it=]
+$x
+   ^{i \leftarrow 0 = ∅}
+   _{\setmathfontalternate{arrow}
+     \setmathfontalternate{dotless}
+     \setmathfontalternate{zero}
+     i \leftarrow 0 = ∅}
+$
+\stopbuffer
+
+\typebuffer[sa:2]
+
+Here we set them in one go:
+
+\startbuffer[sa:3]
+\switchtobodyfont[lucidaot,14.4pt]
+\setupmathrendering[lucidaot][it=]
+$x
+   ^{i \leftarrow 0 = ∅}
+   _{\setmathfontalternate{arrow,dotless,zero}
+     i \leftarrow 0 = ∅}
+$
+\stopbuffer
+\
+\typebuffer[sa:3]
+
+The last example shows how to enable these features globally:
+
+\startbuffer[sa:4]
+\switchtobodyfont[lucidaot,14.4pt]
+\setupmathrendering[lucidaot][it=]
+\setupmathematics[stylealternative={arrow,dotless,zero}]
+$x
+   ^{i \leftarrow 0 = ∅}
+   _{i \leftarrow 0 = ∅}
+$
+\stopbuffer
+
+\typebuffer[sa:4]
+
+The results are collected here:
+
+\startlinecorrection[blank]
+\startcombination[4*1]
+    {\vbox{\hsize.2\hsize\midaligned{\nospacing\getbuffer[sa:1]}}} {\bf nothing}
+    {\vbox{\hsize.2\hsize\midaligned{\nospacing\getbuffer[sa:2]}}} {\bf stepwise}

+
+\startsection[title=Italics and limits]
+
+An \OPENTYPE\ font treats italic correction differently from traditional fonts.
+Officially the italic correction is used for placement above and below limits
+where the scripts shift left and right half of the correction from the center of
+the shape. Advanced kerns are then to be used for anchoring the scripts when they
+are placed at the right side (so far no fonts seem to do this). Because we cannot
+foresee if fonts compensate for correction then we can control placement a bit.
+There is a parameter \type {\mathnolimitsmode} that controls the correction.
+
+\definebodyfontenvironment[20pt]
+
+\startlinecorrection
+\startcombination[5*1]
+    {\ruledhbox to .15\hsize{\hss\showglyphs\switchtobodyfont[20pt]\mathnolimitsmode0$\displaystyle\int\nolimits^0_1$\hss}} {\tttf 0}

+\stopcombination
+\stoplinecorrection
+
+A value larger than 15 is interpreted as a factor (in the usual \TEX\ way 1000
+means 1.0). We have some values left for future use when correction is to be
+combined with kerns.
+
+In \CONTEXT\ we set the value to 1 which means that the factors for super- and
+subscript are set via math parameters (or constants in the font). We use a
+default of \type {{0,800}} so we don't shift the superscript and the subscript we
+shift less than the italic correction. This is driven by a feature but you can
+change the values before loading a font, for instance with:
+
+\starttyping
+\adaptfontfeature[*math*][mathnolimitsmode={100,700}]
+\stoptyping
+
+The defaults come out as:
+
+\startlinecorrection
+\startcombination[5*1]
+    {\ruledhbox to .15\hsize{\hss\showglyphs\switchtobodyfont[modern,  20pt]$\displaystyle\int\nolimits^0_1$\hss}} {\tttf modern}

+\startsection[title=Kerning]
+
+Math kerns in \OPENTYPE\ are quite advanced and use a staircase model left
+and|/|or right of characters. However, hardly any math font implements them
+(extensively). Therefore we provide a way to fine tune your fonts to your
+preferences. You can test this mechanism by patching \type {cambria-math.lfg} by
+adding this to the mathematics subtable:
+
+\starttyping
+kernpairs = {
+    [0x1D44E] = {
+        [0x1D44F] = 1000, -- 𝑎𝑏 demo
+    }
+}
+\stoptyping
+
+After that, the next example should work:
+
+\starttyping
+\starttext
+    \setupbodyfont[cambria]
+    \setupmathematics[kernpairs=yes]
+    $abcd$
+\stoptext
+\stoptyping
+
+There should be a gap between the $𝑎$ and $𝑏$. It is not shown here because I
+don't want to mess up my goodie file.

+\startsection[title=Introduction]
+
+A font definition looks as follows:
+
+\starttyping
+\definefont
+  [MyFont]
+  [namepart method specification size]
+\stoptyping
+
+For example:
+
+\starttyping
+\definefont
+  [MyFont]
+  [Bold*default at 12.3pt]
+\stoptyping
+
+We have already discussed the namepart and size in a previous chapter and here
+we will focus on the method. The method is represented by a character and although
+we currently only have a few methods there can be many more.
+
+\stopsection
+
+\startsection[title=: (direct features)]
+
+This one is seldom used, but those coming from another macro package to \CONTEXT\
+might use it as first attempt to defining a font.
+
+\starttyping
+\definefont
+  [MyFont]
+  [Bold:+kern;+liga; at 12.3pt]
+\stoptyping
+
+This is the \XETEX\ way of defining fonts. A \type {+} means as much as
+\quotation {turn on this feature} so you can guess what the minus sign does.
+Alternatively you can use a key/value approach with semicolons as separator. If
+no value is given the value \type {yes} is assumed.
+
+\starttyping
+\definefont
+  [MyFont]
+  [Bold:kern=yes;liga=yes; at 12.3pt]
+\stoptyping
+
+When we started supporting \XETEX\ we ran into issues with already present
+features of \CONTEXT\ as the \XETEX\ syntax also has some more obscure properties
+using slashes and brackets for signalling a file or name lookup. As in \CONTEXT\
+we prefer a more symbolic approach anyway, it never was a real issue.
+
+\stopsection
+
+\startsection[title=* (symbolic features)]
+
+The most natural way to associate a set of features with a font instance
+is the following:
+
+\starttyping
+\definefont
+  [MyFont]
+  [Bold*default at 12.3pt]
+\stoptyping
+
+This will use the featureset named \type {default} and this one is defined in
+\type {font-pre.mkiv} which might be worth looking at.
+
+\starttyping
+\definefontfeature
+  [always]
+  [mode=auto,
+   script=auto,
+   kern=yes,
+   mark=yes,
+   mkmk=yes,
+   curs=yes]
+
+\definefontfeature
+  [default]
+  [always]
+  [liga=yes,
+   tlig=yes,
+   trep=yes] % texligatures=yes,texquotes=yes
+
+\definefontfeature
+  [smallcaps]
+  [always]
+  [smcp=yes,
+   tlig=yes,
+   trep=yes] % texligatures=yes,texquotes=yes
+
+\definefontfeature
+  [oldstyle]
+  [always]
+  [onum=yes,
+   liga=yes,
+   tlig=yes,
+   trep=yes] % texligatures=yes,texquotes=yes
+
+\definefontfeature % == default unless redefined
+  [ligatures]
+  [always]
+  [liga=yes,
+   tlig=yes,
+   trep=yes]
+
+\definefontfeature % can be used for type1 fonts
+  [complete]
+  [always]
+  [compose=yes,
+   liga=yes,
+   tlig=yes,
+   trep=yes]
+
+\definefontfeature
+  [none]
+  [mode=none,
+   features=no]
+\stoptyping
+
+These definitions show that you can construct feature sets on top of existing
+ones, but keep in mind that they are defined instantly, so any change in the
+parent is not reflected in its kids.
+
+In a font definition you can specify more than one set:
+
+\starttyping
+\definefont
+  [MyFont]
+  [Bold*always,oldstyle at 12.3pt]
+\stoptyping
+
+\stopsection
+
+\startsection[title=@ (virtual features)]
+
+This method is somewhat special as it demands knowledge of the internals
+of the \CONTEXT\ font code. Much of it is still experimental but it is a
+nice playground. A good example of its usage can be found in the file
+\type {m-punk.mkiv} where we create a font out of \METAPOST\ graphics.
+
+Another example is virtual math. As in the beginning of \LUATEX\ and \MKIV\
+there were only a few \OPENTYPE\ math fonts, and as I wanted to get rid
+of the old mechanisms, it was decided to virtualize the math fonts. For
+instance a Latin Modern Roman 10 point math font can be defined as follows:
+
+\starttyping
+\definefontsynonym
+  [LMMathRoman10-Regular]
+  [LMMath10-Regular@lmroman10-math]
+\stoptyping
+
+The \type {lmroman10-math} refers to a virtual definition and in this case
+it is one using a built|-|in constructor and therefore we use a goodies
+file to specify the font. That file looks as follows:
+
+\starttyping
+return {
+  name = "lm-math",
+  version = "1.00",
+  comment = "Goodies that complement latin modern math.",
+  author = "Hans Hagen",
+  copyright = "ConTeXt development team",
+  mathematics = {
+    ...
+    virtuals = {
+      ...
+      ["lmroman10-math"] = ten,
+      ...
+    },
+    ...
+  }
+}
+\stoptyping
+
+Here \type {ten} is a previously defined table:
+
+\startnarrowtyping
+local ten = {
+  { name = "lmroman10-regular.otf", features = "virtualmath", main = true },
+  { name = "rm-lmr10.tfm", vector = "tex-mr-missing" } ,
+  { name = "lmmi10.tfm", vector = "tex-mi", skewchar = 0x7F },
+  { name = "lmmi10.tfm", vector = "tex-it", skewchar = 0x7F },
+  { name = "lmsy10.tfm", vector = "tex-sy", skewchar = 0x30, parameters = true } ,
+  { name = "lmex10.tfm", vector = "tex-ex", extension = true } ,
+  { name = "msam10.tfm", vector = "tex-ma" },
+  { name = "msbm10.tfm", vector = "tex-mb" },
+  { name = "stmary10.afm", vector = "tex-mc" },
+  { name = "lmroman10-bold.otf", vector = "tex-bf" } ,

+\stopnarrowtyping
+
+This says as much as: take \type {lmroman10-regular.otf} as starting point
+and overload slots with ones found in the following fonts. The vectors are
+predefined as they are shared with other font sets like \type {px} and
+\type {tx}.
+
+In due time more virtual methods might end up in \CONTEXT\ because they are
+a convenient way to extend or manipulate fonts.

+\startsection[title=Lua fonts]

+You can define a font in \LUA. In the process you can use all kind of helper
+functions that \CONTEXT\ provides. Here is an example:
+
+\typefile{fonts-demo-rule.lua}
+
+This code is stored in \type {fonts-demo-rule.lua} and we can load that font
+in the usual way, by specifying a filename:

+\stopbuffer
+
+\typebuffer
+
+\getbuffer

+{\MyRuleFont So when we use it we get text typeset where all vowels are replaced
+by rules. The actualtext injection (in theory) makes it possible to cut and paste
+the text from the \PDF\ document but while writing this (mid 2016) a {\maincolor
+\type {mupdf}} based viewer couldn't handle it and {\maincolor \type {acrobat}}

+\startsection[title=Old fuzzy fonts]
+
+Most natural is to use \OPENTYPE\ or \TYPEONE\ fonts. In the case of \TYPEONE\ a
+matching pair of \type {afm} and \type {pfb} files is needed. However, there can
+be situations where there is only a \type{tfm} and \type {pfb} file (or not even
+that: just a bitmap file).
+
+I will not show specimen here, simply because I don't have (nor want to have) the
+fonts needed in my development and production environments. The implementation
+was tested with a specific czech computer modern font.
+
+In a traditional (8 bit) setup we have an \type {tfm} file, a \type {pfb} file
+and a \type {enc file}. The order of the characters in the \type {tfm} file
+directly relates to the input encoding. The \type {enc} file relates that order
+to the order in the \type {pfb} file. The mapping from input encoding to font
+shape encoding happens via glyph names. In the \type {map} file we tell what
+\type {pfb} file to use with what \type {enc} file.
+
+However, in the case of the \type {csr.tfm} and \type {csr.pfb} file it looks
+like in practice the \type {enc} file is not used, probably because in the \type
+{pfb} file the standard encoding matches the order in the \type {tfm} file. This
+is of course a rather dangerous assumption, especially if information lacks to
+check it.
+
+The next example definitions demonstrate several paths to go from \UNICODE\ input
+(source file) to rendered shapes. As this is mostly meant for generic usage we
+use the low level definition code (\CONTEXT\ users are not supposed to use that
+method).
+
+\starttyping
+\font\foo=file:csr10.tfm:reencode=auto;mode=node;liga=yes;kern=yes
+\stoptyping
+
+This is the easiest way. We use the \type {tfm} file for dimensions, ligatures
+and kerns. The \type {auto} option will use the \type {pfb} file to identify the
+right mapping. We enable ligatures and kerns and we use node mode. This indicates
+that we're dealing with a pseudo \OPENTYPE\ setup here. You can provide a \type
+{pfb} file with the \type {pfbfile} feature in case the name differes from the
+\type {tfm} file.
+
+\starttyping
+\font\foo=file:csr10.tfm:reencode=csr.enc;mode=node;liga=yes;kern=yes
+\stoptyping
+
+Now we use the \type {enc} file for the encoding vector but we still need the
+\type {pfb} file for mapping that onto the right shape. You probably can best use
+\type {auto} instead.
+
+\starttyping
+\font\foo=file:csr10.tfm:reencode=csr.enc;bitmap=yes;mode=node;liga=yes;kern=yes
+\stoptyping
+
+Here we force bitmap shapes. This is a bit tricky as a different code path is
+followed in the backend. Unless the situation is too confusing, a proper \type
+{ToUnicode} is included in the output, so that cut and paste works all right,
+given that the viewer is able to deal with it (always use \ACROBAT\ as
+reference).
+
+Why do we need modes and|/|or to simulate \OPENTYPE\ behaviour? Indeed it seldom
+makes sense with \type {tfm} files but in this particular case teh font has a
+quote cheat.
+
+\starttyping
+\startluacode
+    fonts.handlers.otf.addfeature {
+        name = "czechdqcheat",
+        type = "substitution",
+        data = {
+            quotedblright = "csquotedblright",
+        },
+    }
+\stopluacode
+\stoptyping
+
+We could make this a language specific feature but as this font is not meant for
+other languages it makes no sense to do so. This feature is enabled with:
+
+\starttyping
+czechdqcheat=yes
+\stoptyping
+
+This will replace one quote by another with different side bearings. Of course a
+properly bounded quote with proper kerning makes much more sense. A test case is:
+
+\starttyping
+\quotedblleft  X\quotedblright
+\quotedblright X\quotedblleft

+\startsection[title=Introduction]
+
+We use the term modes for classifying the several ways characters are turned into
+glyphs. When a font is defined, a set of features can be associated and one of
+them is the mode.
+
+\starttabulate[|l|p|]
+\NC none \NC Characters are just mapped onto glyphs and no substitution or
+             positioning takes place. \NC \NR
+\NC base \NC The routines built into the engine are used. For many Latin fonts
+             this is a rather useable and efficient method. \NC \NR
+\NC node \NC Here alternative routines written in \LUA\ are used. This mode is
+             needed for more complex scripts as well as more advanced features
+             that demand some analysis. \NC \NR
+\NC auto \NC This mode will determine the most suitable mode for the given
+             feature set. \NC \NR
+\stoptabulate
+
+When we talk about features, we refer to more than only features provided by
+fonts as \CONTEXT\ adds some of its own. In the following section each of these
+modes is discussed. Before we do so a short introduction to font tables that we
+use is given.
+
+\stopsection
+
+\startsection[title=The font table]
+
+The internal representation of a font in \CONTEXT\ is such that we can
+conveniently access data that is needed in the mentioned modes. When a font is
+used for the first time, or when it has changed, it is read in its most raw form.
+After some cleanup and normalization the font gets cached when it is a \TYPEONE\
+or \OPENTYPE\ font. This is done in a rather efficient way. A next time the
+cached copy is used.
+
+The normalized table is shared among instances of a font. This means that when a
+font is used at a different scale, or when a different feature set is used, the
+font gets loaded only once and its data is shared when possible. In \in {figure}
+[fig:tfm-loading] we have visualized the process. Say that you ask for font \type
+{whatever} at \type {12pt} using featureset \type {smallcaps}. In low level code
+this boils down to:
+
+\starttyping
+\font\MySmallCaps=whatever*smallcaps at 12pt
+\stoptyping
+
+In \CONTEXT\ we have overloaded the font loader so \LUA\ code takes care of the
+loading. Basically there is a function hooked into \LUATEX's font definer (the
+\type {\font} primitive) that returns a table and from that on \LUATEX\ will
+create its internal representation that is identified by a number, the so called
+font id. So, in fact the \type {\Whatever} command is a reference to a font id, a
+positive number. When this font is already loaded, \CONTEXT\ will reuse the id
+and pas that one.

+\stopplacefigure
+
+The first step is loading the font (or using the cached copy). From that a copy
+is made that has some additional data concerning the features set and from that a
+scaled copy is constructed. These copies share as much data as possible to keep
+the memory footprint as small as possible. The table that is passed to \LUATEX\
+gets cleaned up afterwards. In practice the \TFM\ loader only kicks in for
+creating virtual math fonts. The \AFM\ reader is used for \TYPEONE\ fonts and as
+there is no free upgrade path from \TYPEONE\ to \OPENTYPE\ for commercial fonts,
+that one will get used for older fonts. Of course most loading is done by the
+\OTF\ reader(s).
+
+\appendixdata{\in[fonts:trackers:tables]}
+
+The data in the final \TFM\ table is organized in subtables. The biggest ones are
+the \type {characters} and \type {descriptions} tables that have information
+about each glyph. Later we will see more of that. There are a few additional
+tables of which we show two: \type {properties} and \type {parameters}. For the
+current font the first one has the following entries:
+
+\showfontproperties
+
+The \type {parameters} table has variables that have been (re)assigned in the
+process. A period in the key indicates that we are dealing with a subtable, for
+instance \type {expansion}.
+
+\showfontparameters
+
+To give you an impression of what we are dealing with, the positional features
+are shown next:
+
+\showfontpositionings
+
+The substitution features of the current font are as follows:
+
+\showfontsubstitutions
+
+This is clearly an \OPENTYPE\ font. Normally there are a default
+script and default language supported. If this is not the case you
+need to provide them as part of the featureset, otherwise there
+will be no features applied.
+
+\stopsection
+
+\startsection[title=Base mode]
+
+We talk of base mode processing when the font machinery is used that is built in
+\LUATEX. So what does this traditional mechanism provide?
+
+Before we discuss this, a somewhat simplified model of how \TEX\ works has to be
+given. Say that we have the following input:
+
+\starttyping
+\def\bla{BLA}
+test \bla test
+\stoptyping
+
+This input gets translated into tokens and those tokens are either processed
+later or they become something else directly. Take the first line. Characters in
+the input have a so called catcode property that determines how the parser
+tokenized them. Effectively we therefore get something like this:
+
+\starttyping
+<command def>
+<command bla>
+<begingroup>
+<character B>
+<character L>
+<character A>
+<endgroup>
+\stoptyping
+
+and finally in the hash table there will be an entry for \type {bla} that has the
+meaning \type {BLA} expressed in three characters.
+
+The second line refers to \type {\bla} and in the process this macro gets
+expanded, so we get:
+
+\starttyping
+<character t>
+<character e>
+<character s>
+<character t>
+<space>
+<character B>
+<character L>
+<character A>
+<character t>
+<character e>
+<character s>
+<character t>
+\stoptyping
+
+Because the parser gobbles spaces after a macro name, there is no space before
+the second \type {test}. In practice there will be no intermediate list like
+this, because as soon as possible \TEX\ will add something to a so called node
+list. When the moment is there, this list will be passed to the typesetting
+routine that constructs a horizontal list. Later this list can be converted into
+a horizontal box or broken into lines when it concerns a paragraph.
+
+In traditional \TEX\ characters are stored into char nodes and the builder turns
+them into glyph nodes. In \LUATEX\ they start out as glyph nodes and the subtype
+number will flag them as glyphs. Any value larger than 255 is a signal that the
+list has been processed. The previous example leads to the list shown in \in
+{figure} [nodechart:1a].
+
+\startplacefigure[title={The text \quote {\typ {test BLAtest}} converted to nodes.},reference=nodechart:1a]
+    \getbuffer[nodechart:1a]
+\stopplacefigure
+
+Here we have turned off inter|-|character kerning and hyphenation. When we turn
+that on, we get a slightly more complex list, as shown in \in {figure}
+[nodechart:1b]. Hyphenation points are represented by discretionary nodes and
+these have pointers to a pre break, post break and replacement text.
+
+\startplacefigure[title={The text \quote {\typ {test BLAtest}} converted to nodes, hyphenated and kerned.},reference=nodechart:1b]
+    \getbuffer[nodechart:1b]
+\stopplacefigure
+
+In addition to hyphenation and kerning we can have ligatures. The list in \in
+{figure} [nodechart:2a] shows that we get a reference to a ligature in the glyph
+node but that the components are still known. This figure also demonstrates that
+the ligature is build in steps.
+
+\startplacefigure[title={The rendering of the word \quote {\typ {affiliation}}.},reference=nodechart:2a]
+    \getbuffer[nodechart:2a]
+\stopplacefigure
+
+% \appendixdata{\in[nodes:discretionaries]}
+
+If we insert an explicit \type {\discretionary} command, we see in
+\in {figure} [nodechart:2b] that we get three variants. In \in
+{figure} [nodechart:2c] we render some Dutch words and these have
+quite some ligatures.
+
+\startplacefigure[title={The rendering of the bogus word \quote {\typ {abcghi}} with an
+        explicit discretionary added.},reference=nodechart:2b]

+\startplacefigure[title={The rendering of the Dutch words \quote { \typ{effe fijn fietsen}}.},reference=nodechart:2c]
+    \getbuffer[nodechart:2c]
+\stopplacefigure
+
+So, we have hyphenation, ligature building and kerning and to some extent these
+mechanisms hook into each other. This process is driven by information stored in
+the font and rules related to the language. The hyphenation happens first, so the
+builder just sees discretionary nodes and needs to act properly on them. Although
+languages play an important role in formatting the text, for the moment we can
+forget about that. This leaves the font.
+
+As we already mentioned in a previous chapter, in \CONTEXT\ we use \UNICODE\
+internally. This also means that fonts are organized this way. By default the
+glyph representation of a \UNICODE\ character sits in the same slot in the glyph
+table. All additional glyphs, like ligatures or alternates are pushed in the
+private unicode space. This is why in the lists shown in the figures the
+ligatures have a private \UNICODE\ number.
+
+The basic mode of operation in the builder in \LUATEX\ is as follows:
+
+\startitemize[packed]
+\startitem hyphenate the node list \stopitem
+\startitem build ligatures \stopitem
+\startitem inject kerns \stopitem
+\startitem optionally break into lines \stopitem
+\stopitemize
+
+In traditional \TEX\ the first step is not that independent. There hyphenation
+takes place when the text is broken into lines, and only in places that are
+candidate for such a break. In \LUATEX\ the whole text is hyphenated. This has
+the advantage that the steps are clearly separated and that no complex
+reconstruction and re|-|hyphenation has to take place. The speed penalty can be
+neglected and the extra memory overhead is small compared to what is needed
+anyway.
+
+In base mode the raw font data is read in and from that only basic information is
+used to construct the \TFM\ table: dimensions, ligatures and kerns. In a node
+list, all glyph ranges that refer to such a font get the standard ligature and
+kern routines applied, but only if the subtype is still less than 256. This check
+on subtype prevents duplicate processing that might happen as a side effect of
+for instance unboxing some material in a yet to be typeset text.
+
+Given that the majority of what \TEX\ has to deal with is relatively simple latin
+script, base mode processing is rather convenient and efficient. It is also the
+reference point of other kinds of processing. The most simple way to force base
+mode is the following:
+
+\starttyping
+\definefontfeature[basemode][mode=base,kern=yes,liga=yes]
+
+\definefont[MyTitleFont][SerifBold*basemode at 12pt]
+\stoptyping
+
+Here \type {\MyTitleFont} will be a bold serif with ligatures and kerns applied.
+However, as an \OPENTYPE\ font can have many features, the following definitions
+are also valid:
+
+\starttyping
+\definefontfeature[basemode-o][mode=base,kern=yes,onum=yes,liga=yes]
+\definefontfeature[basemode-s][mode=base,kern=yes,smcp=yes]
+\stoptyping
+
+The \TFM\ constructor will filter the right information from the font data and
+construct a proper table based on these specifications. But you need to keep in
+mind that when for instance old style numerals or small caps are activated, that
+their rendering (the glyph) will always be used. So, for instance \type {3} and
+\type {A} keep their \UNICODE\ points but as part of their specification they
+will get an index pointing to the oldstyle or small caps variant and the
+dimensions of that shape will be used.
+
+\stopsection
+
+\startsection[title=Node mode]
+
+Node mode is by far the most interesting of the modes. When enabled we only pass
+a few properties of glyphs to the engine: the width, height and depth and
+optionally protrusion, expansion factors as well as some extra \CONTEXT\ specific
+quantities. So there is no kerning and no ligature building done by the engine.
+Instead we do this in \LUA\ by walking over the node list and checking if some
+action is needed.
+
+\appendixdata{\in[fonts:trackers:features]}
+
+The default feature set enables kerning and ligature building for default and/or
+Latin scripts and the default language. Being a relative simple feature,
+ligatures don't take much action. Next we show a trace of a ligature replacement.
+
+\blank
+\showotfcomposition{name:dejavuserif*default at 24pt}{1}{affiliation}
+\blank
+
+Be warned that this \type {f f i} sequence not always becomes a ligature.
+Actually this is one area where tradition is quite visible: for some reason most
+fonts do have these f|-|related ligatures but lack others. These ligatures even
+have code points in \UNICODE\ which is quite debatable. Just as there are fonts
+with hardly any kerns (like Lucida) there are fonts that follow a different route
+to improve the look and feel of neighbouring glyphs, like Cambria:
+
+\blank
+\showotfcomposition{name:cambria*default at 24pt}{1}{affiliation}
+\blank
+
+Instead of representing multiple characters by one glyph the designer has decided
+to replace the \type {f} by a slightly narrower one so that the dot of the \type
+{i} stays loose.
+
+An example where much more is involved is the following. The Husayni font that is
+used for typesetting Arabic is built upon a solid but complex \OPENTYPE\
+foundation and can only be dealt with in node mode. When the \LUATEX\ project
+started we assumed that more power in the engine was needed to accomplish this,
+but so far the results with standard \OPENTYPE\ functionality are quite good.
+\CONTEXT\ has an additional paragraph optimizer that can apply additional
+features to get even better results but discussing this falls beyond this
+chapter. A trace of just one Arabic word is much longer than the previously shown
+traces.
+
+\blank
+\showotfcomposition{name:husayni*otftracker-husayni at 48pt}{-1}{فَخَا}
+\blank
+
+What we see here is a stepwise substitution process, sometimes based on a
+contextual analysis, followed by positioning. The coloring concerns the outcome
+of the analysis which in this case flags initial, final, medial and isolated
+characters.
+
+The starting point of this Arabic word is visualized in \in {figure}
+[nodechart:3a] and as expected we see no discretionary nodes here. The result as
+seen in \in {figure} [nodechart:3b] has (interestingly) no kerns as all
+replacements happen via offsets in the glyph node.

+\stopsection
+
+\startsection[title=Auto mode]
+
+Base mode is lean and mean and relatively fast while node mode is more powerful
+and slower. So how do you know what to choose? The safest bet is to use node mode
+for everything. In \CONTEXT\ however, we also have the so called auto mode. In that
+case there is some analysis going on that chooses between base mode and node mode
+depending on the boundary conditions of script and language and there are specific
+demands in terms of feature processing. So, auto mode will resolve to base or
+node mode.
+
+\stopsection
+
+\startsection[title=None mode]
+
+Sometimes no features have to be applied at all. A good example is verbatim.
+There you don't want ligatures, kerning or fancy substitutions. Contrary to what
+you might expect, monospaced fonts can have such features. Some might actually
+make sense, like rendering zeros. However, you cannot assume such a feature to be
+present so this is an example of where some more knowledge about a particular
+font is needed. This is what Latin Modern provides.

+\stopsection
+
+\startsection[title=Dynamics]
+
+Sometimes you want to enable or disable a specific feature only for a specific
+span of text. Defining a font for only this occasion is overkill, especially when
+for instance features are used to fine|-|tune the typography as happens in the
+Oriental \TEX\ project, which is related to \LUATEX. Instead of defining yet
+another font instance we can therefore enable and disable specific features. For
+this it is not needed to know the current font and its size. \footnote {Dynamics
+are a \CONTEXT\ specific feature and is not available in the generic version of
+the font code. There are several reasons for this: it complicates the code, it
+assumes the \CONTEXT\ feature definition mechanism to be used, and it is somewhat
+slower as some extra analysis has to be done.}
+
+Dynamics are a special case of node mode and you don't need to set it up when
+defining a font. In fact, a font defined in base mode can also be dynamic. We
+show some simple examples of applying dynamic features.
+
+% First we define two feature sets, one for ligatures and one for oldstyle. As in
+% our example we want to start fresh we also define a simple set with only kerning
+% enabled. In a next chapter we will see more of how featuresets are defined.

+% \stopbuffer
+%
+% We use the following test line:
+%
+% \typebuffer
+%
+% In the first line we do nothing but in the following lines we add features to the
+% font (replacing existing ones), we add features to the current set (nothing gets
+% replaced) and finally we remove some from the set. The typeset result is shown in
+% \in {figure} [fig:modes:dynamics].
+%
+% \placefigure
+%   [here]

+%   {Selectively applying ligatures and oldstyle numerals using dynamic features in
+%    Latin Modern Roman.}
+%   {\color[maincolor]{\externalfigure[demo.buffer][width=.75\textwidth]}}
+%
+% Although for reasons of symmetry we have a few more commands, in practice only
+% the following make sense, and even the first one is mostly of interest or
+% testing.
+%
+% \starttabulate[|l|l|]
+% \NC \type {\addff} \NC set a feature to be the one applied   \NC \NR
+% \NC \type {\addfs} \NC add a feature to current set          \NC \NR
+% \NC \type {\subfs} \NC remove a feature from the current set \NC \NR
+% \stoptabulate
+%
+% Keep in mind that the given feature set can set a combination of
+% features. Also be aware of the fact that these commands don't
+% accumulate: the last one is applied.
+
+% A more sophisticated dynamic feature mechanism is the following. This
+% time we do stack up features. We can add, subtract or even replace
+% feature sets.
+
+Let's first define some feature sets:
+
+\startbuffer
+\definefontfeature[f:smallcaps][smcp=yes]
+\definefontfeature[f:nocaps]   [smcp=no]
+\definefontfeature[f:oldstyle] [onum=yes]
+\definefontfeature[f:newstyle] [onum=no]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can add and subtract these features from the current feature set
+that is bound to the current font.
+
+\startbuffer
+\switchtobodyfont[pagella]    123 normal
+\addfeature     {f:oldstyle}  123 oldstyle
+\addfeature     {f:smallcaps} 123 olstyle smallcaps
+\subtractfeature{f:oldstyle}  123 smallcaps
+\subtractfeature{f:smallcaps} 123 normal
+\stopbuffer
+
+\typebuffer
+
+Here we choose a font that has oldstyle numerals as well as small caps: pagella.
+
+\blank \start \getbuffer \stop \blank
+
+The following does the same, but only uses addition:
+
+\startbuffer
+\switchtobodyfont[pagella] 123 normal
+\addfeature{f:oldstyle}    123 oldstyle
+\addfeature{f:smallcaps}   123 olstyle smallcaps
+\addfeature{f:newstyle}    123 smallcaps
+\addfeature{f:nocaps}      123 normal
+\stopbuffer
+
+\typebuffer
+
+You can also completely replace a feature set. Of course the set is only
+forgotten inside the current group.
+
+\startbuffer
+\switchtobodyfont[pagella]   123 normal
+\addfeature    {f:oldstyle}  123 oldstyle
+\addfeature    {f:smallcaps} 123 olstyle smallcaps
+\replacefeature{f:oldstyle}  123 oldstyle
+\replacefeature{f:smallcaps} 123 smallcaps
+\stopbuffer
+
+\typebuffer
+
+and now we get:
+
+\blank \start \getbuffer \stop \blank
+
+You can exercise some control with \type {\resetfeature}:
+
+\startbuffer
+\switchtobodyfont[pagella]   123 normal
+\addfeature    [f:oldstyle]  123 oldstyle
+\addfeature    [f:smallcaps] 123 olstyle smallcaps
+\resetfeature                123 reset
+\addfeature    [f:oldstyle]  123 oldstyle
+\addfeature    [f:smallcaps] 123 olstyle smallcaps
+\stopbuffer
+
+\typebuffer
+
+Watch how we use the \type {[]} variant of the commands. The braced and
+bracketed variants behave the same.
+
+\blank \start \getbuffer \stop \blank
+
+There is also a generic command \type {\feature} that takes two arguments. Below
+we show all calls, with long and short variants:
+
+\starttyping
+\addfeature        [f:mine] \feature [more][f:mine] \feature[+][f:mine]
+\subtractfeature   [f:mine] \feature [less][f:mine] \feature[-][f:mine]
+\replacefeature    [f:mine] \feature  [new][f:mine] \feature[=][f:mine]
+\resetandaddfeature[f:mine] \feature[local][f:mine] \feature[!][f:mine]
+\revivefeature     [f:mine] \feature  [old][f:mine] \feature[>][f:mine]
+\resetfeature               \feature[reset]         \feature[<]
+\stoptyping
+
+Each variant also accepts \type {{}} instead of \type {[]} so that they can
+conveniently be used in square bracket arguments. As a bonus, the following also
+works:
+
+\startbuffer
+\switchtobodyfont[pagella]
+123 normal
+\feature[+][f:smallcaps,f:oldstyle]
+123 SmallCaps and OldStyle

+

+\stopsection
+
+\startsection[title=Discretionaries]
+
+One of the complications in supporting more complex features is that we can have
+discretionary nodes. These are either inserted by the hyphenation engine, or
+explicitly by the user (directly or via macros). In most cases we don't need to
+bother about this. For instance, more demanding scripts like Arabic don't
+hyphenate, languages using the Latin script seldom want ligatures at hyphenation
+points (as they can be compound words) and|/|or avoid confusing hyphenation
+points, so what is left are specific user inserted discretionaries. Add to that,
+that a proper font has not much kerning between lowercase characters and it will
+be clear that we can ignore most of this. Anyway, as we explicitly deal with user
+discretionaries, the next works out okay. Watch how we normally only have
+something special in the replacements text that shows up when no hyphenation is
+needed.

+
+In base mode such things are handled by the \TEX\ engine itself and it can deal
+with pretty complex cases. In node mode we use a simplification which in practice
+suffices. We will come back to this in \in {section} [ligatures:hyphenation].
+
+\stopsection
+
+\startsection[title=Efficiency]
+
+The efficiency of the mechanisms described here depends on several factors. It
+will be clear that the larger the font, the more time it will take to load it.
+But what is large? Most \CJK\ fonts are pretty large but also rather simple. A
+font like Zapfino on the other hand covers only latin but comes with many
+alternative shapes and a large set of rules. The Husayni font focusses on Arabic,
+which in itself has not that large an alphabet, but being an advanced script
+font, it has a lot of features and definitely a lot of rules.
+
+In terms of processing it's safe to say that Latin is of average complexity. At
+most you will get some substitutions, like regular numerals being replaced by
+oldstyles, or ligature building, which involves a bit of analysis, and some
+kerning at the end. In base mode the substitutions have no overhead, simply
+because the character table already has references to the substituents and the
+replacement already takes place when defining the font. There ligature building
+and kerning are also fast because of the limited amount of lookups that also are
+already kept with the characters. In node mode however, the lists have to be
+parsed and tables have to be consulted so even Latin processing has some
+overhead: each glyph node is consulted and analyzed (either or not in its
+context), often multiple times. However, the code is rather optimized and we use
+caching of already analyzed data when possible.
+
+A \CJK\ script is somewhat more complex on the one hand, but pretty simple on the
+other. Instead of font based kerning, we need to prevent or encourage breaks
+between certain characters. This information is not in the font and is processed
+otherwise but it does cost some time. The font part however is largely idle as
+there are no features to be applied. Even better, because the glyphs are large
+and the information density is high, the processing time per page is not much
+different from Latin. Base mode is good enough for most \CJK.
+
+The Arabic script is another matter. There we definitely go beyond what base mode
+offers so we always end up in node mode. Also, because there is some analysis
+involved, quite some substitutions and in the end also positioning, these are the
+least efficient fonts in terms of processing time. Of course the fact that we mix
+directions also plays a role. If in the Husayni font you enable 30 features with
+an average of 5 rules per feature, a 300 character paragraph will take 45.000
+actions. \footnote {For a modern machine this amount is no real issue, but as
+each action involves function calls and possibly some garbage collection there
+is some price to pay.} When multiple fonts are combined in a paragraph there will
+be more sweeps over the list and of course the replacements also have to happen.
+
+In a time when the average photo camera produces megabyte pictures it makes no
+sense to whine about the size of a font file. On the other hand as each font
+eventually ends up in memory as a \LUA\ table, it makes sense to optimize that
+bit. This is why fonts are converted into a more efficient intermediate table
+that is cached on disk. This makes loading a font quite fast and due to shared
+tables memory usage rather efficient. Of course a scaled instance has to be
+generated too, but that is acceptable. To some extent loading and defining a font
+also depends on the way the macro package is set up.
+
+When comparing \LUATEX\ with for instance \PDFTEX\ or \XETEX\ you need to take
+into account that in \CONTEXT\ \MKIV\ we tend to use \OPENTYPE\ fonts only so
+there are less fonts loaded than in a more traditional setup. In \CONTEXT\
+startup time of \MKIV\ is less than \MKII\ although overall processing time is
+slower, which is due to \UNICODE\ being used and more functionality being
+provided. On the other hand, immediate \METAPOST\ processing and more clever
+multipass handling wins back time. The impact of fonts on processing time in a
+regular document is therefore not that impressive. In practice a \MKIV\ run can
+be faster than a \MKII\ run, especially when \METAPOST\ is used.
+
+In \CONTEXT\ processing of node lists with respect to fonts is only one of the
+many manipulations of such lists and by now fonts are not really the bottleneck.
+The more not font related features users demand and enable, the less the relative
+impact of font processing becomes.
+
+Also, there are some advanced typographic extras that \LUATEX\ offers, like
+protrusion (think of hanging punctuation) and hz optimization (glyph scaling) and
+these slow down processing quite a lot, and they are not taking place at the
+\LUA\ end at all, but this might change in \MKIV. And, of course, typesetting
+involves more than fonts and other aspects can be way more demanding.

+This is the zero issue of a range of \CONTEXT\ related publications, in most
+cases short introductions to new functionality. The style may be used by users
+for providing similar documents, but preferably not for other purposes, since it
+may confuse readers in their expectations.
+
+We've chosen a layout which is more functional than beautiful. This layout
+provides several text areas: headers and footers, margins and edges as well as a
+main text area. The surrounding (gray or color) makes the main page (which is
+slightly smaller than A4) stand out and is suitable for viewing in spread mode.
+
+The documents produced at \PRAGMA\ are called {\bf This Way}, user documents gets
+the title {\bf My Way}. The \PRAGMA\ issues are numbered. We strongly advise you
+not to use the \type {mag-} prefix for your issues, since this may lead to
+clashes with files distributed by \PRAGMA.

+
+This is a simple example of using subpage numbers. Subpage numbers are not
+automatically kept track of, so you first need to activate them:

+\startbuffer
+\setupsubpagenumber

+\stopbuffer

+\typebuffer \getbuffer

+    Occasionally we experiment a bit with (\PDF) features that are useful but at
+    the same time dangerous when applied uncontrolled. In the process of cleaning
+    up some files in my source tree and triggered by a discussion about overprint
+    I decided to move some of that code into the kernel. You are warned!
+\stopbuffer
+
+
+\startdocument
+  [title={A Few Dangerous Features},
+   author=Hans Hagen,
+   affiliation=PRAGMA ADE,
+   date=June 2004,
+   number=6 \MKIV]
+
+\subject{Remark}
+
+The features discussed here have a so called global character, i.e. all settings
+are global by nature. Future releases may introduce (and by default change to)
+local behaviour. So, don't make your documents depending on local/global
+behaviour. In most cases you will probably not notice the difference.
+
+\subject{Being negative}
+
+The \CONTEXT\ page imposition machinery provides negation because sometimes
+raster image processors need that feature. In that case negation is applied to
+the whole page. Within the document stream inverted colors are normally (and
+best) realized with defining an appropriate color. For special purposes we also
+provide negation
+
+\startbuffer
+\startcolor[red]\ignorespaces
+    \input ward
+    \startnegative\ignorespaces
+        \input ward
+        \startpositive\ignorespaces
+            \input ward
+        \removeunwantedspaces\stoppositive
+        \input ward
+    \removeunwantedspaces\stopnegative
+    \input ward
+\removeunwantedspaces\stopcolor
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can also apply negation to graphic, but the result may not be what we expect.
+While writing this document \in {figure} [fig:negated] negates well when view in
+\GHOSTSCRIPT\ but \ACROBAT~6 shows a strange vertical line pattern.
+
+\startbuffer
+\startcombination
+  {\startpositive
+     \externalfigure[hacker.jpg][width=4cm]%
+   \stoppositive}
+  {normal}
+  {\startnegative
+     \externalfigure[hacker.jpg][width=4cm]%
+   \stopnegative}
+  {negative}
+\stopcombination
+\stopbuffer
+
+\typebuffer
+
+\placefigure
+  [here] [fig:negated]
+  {Negation of graphics.}
+  {\getbuffer}
+
+\subject{Font effects}
+
+Another bag of tricks concerns font effects. As with negation and the to be
+discussed overprint these are implemented using the \CONTEXT\ (still
+experimental) feature handler, but this time we don't provide direct commands.
+Instead we use arguments to control the effects.
+
+\startbuffer
+In this paragraph we have \starteffect[hidden]hidden a piece of
+text\stopeffect. How useful this feature is depends on the kind
+of documents you make. An alternative is to put the text in a
+viewer layer (\starteffect[hidden]as provided by \PDF\stopeffect)
+that is hidden, but since that feature is not widely available
+the effects approach is safer.
+\stopbuffer
+
+\typebuffer \getbuffer
+
+More interesting is changing the way a font is rendered. An outline version is
+rendered with the \type {outer} effect.
+
+\startbuffer
+\bf \starteffect[outer]\input ward \stopeffect \par
+\stopbuffer
+
+\typebuffer \start \getbuffer \stop
+
+The \type {inner} effect is the normal one so there is no reason to show it here.
+The \type {both} option combines the two resulting in an extra bold version.
+
+\startbuffer
+\bf \starteffect[both]\input ward \stopeffect \par
+\stopbuffer
+
+\typebuffer \start \getbuffer \stop
+
+You can influence the linewidth as is demonstrated in the following example:
+
+\startbuffer
+\setupeffect[outer][rulethickness=.8pt]
+\bfd \starteffect[outer]Bigger is Beautiful\stopeffect
+\stopbuffer
+
+\typebuffer \start \getbuffer \stop
+
+Speaking of 2004, in \CONTEXT\ (read: \TEX) intercharacter spacing can only be
+achieved by macro processing. The next method works well, but you need to
+manipulate the \type {\hsize} yourself, since the typesetting engine is unaware
+of this backend manipulation.
+
+\startbuffer
+\setupeffect[both][stretch=2]
+\setupalign[right]
+\dontleavehmode \hsize=.6\hsize
+\bf \starteffect[both]\input ward \stopeffect \par
+\stopbuffer
+
+\typebuffer \start \getbuffer \stop
+
+The \type {normal} (or \type {inner}) alternative looks as follows:
+
+\startbuffer
+\setupeffect[normal][stretch=2]
+\setupalign[right]
+\dontleavehmode \hsize=.6\hsize
+\bf \starteffect[normal]\input ward \stopeffect \par
+\stopbuffer
+
+\typebuffer \start \getbuffer \stop
+
+\subject{Overprint and knockout}
+
+Another feature that should be used with care is overprint. Normally a raster
+image processor will knock out colored areas under colored text or areas on top.
+This works well when the printing engine (or press) is able to precisely align
+the color plates. If not, you will get artifacts that show up as follows (often
+such effects occur in newspapers and cheap magazines):
+
+\definelayer[fake][width=6cm,height=4cm]
+
+\setlayerframed
+  [fake]
+  [preset=lefttop]
+  [frame=off,width=8cm,height=4cm,
+   background=color,backgroundcolor=blue,foregroundcolor=white]
+  {\definedfont[SerifBold at 6\bodyfontsize]cheap}
+
+\setlayerframed
+  [fake]
+  [preset=lefttop,offset=1pt]
+  [frame=off,width=8cm,height=4cm,
+   foregroundcolor=tblack]
+  {\definedfont[SerifBold at 6\bodyfontsize]cheap}
+
+\startbaselinecorrection
+\tightlayer[fake]
+\stopbaselinecorrection
+
+On the one hand we get white spots and depending on how well the ink covers, we
+can get darker spots as well. In such cases it's best to overprint the
+background, which of course only works as expected when the top color is a well
+covering black. Otherwise we probably may have to compensate the color, which in
+turn depends on the kind of paper used.
+
+At the document level, you can set the overprint with:
+
+\starttyping
+\setupcolors[overprint=yes]
+\stoptyping
+
+We show a few examples of local usage: a simple application first (\in {figure}
+{a} [fig:overprint]):
+
+\startbuffer[a]
+\framed
+  [background=color,backgroundcolor=ocyan,
+   frame=off,offset=.25cm,strut=no]
+  {\bfb\setstrut
+   \startoverprint
+   \framed
+     [background=color,backgroundcolor=omagenta,
+      foregroundcolor=oyellow,align={lohi,middle},
+      frame=off,width=2.5cm,height=2cm]
+     {overprint\\\startknockout knockout \stopknockout}%
+   \stopoverprint
+   \framed
+     [background=color,backgroundcolor=omagenta,
+      foregroundcolor=oyellow,align={lohi,middle},
+      frame=off,width=2.5cm,height=2cm]
+     {knockout\\\startoverprint overprint\stopoverprint}}%
+\stopbuffer
+
+\typebuffer[a]
+
+We can nest overprint and turn it off as well (\in {figure} {b} [fig:overprint]):
+
+\startbuffer[b]
+\startoverprint
+\framed
+  [background=color,backgroundcolor=ocyan,
+   frame=off,offset=.25cm,strut=no]
+  {\bfb\setstrut
+   \framed
+     [background=color,backgroundcolor=omagenta,
+      foregroundcolor=oyellow,align={lohi,middle},
+      frame=off,width=2.5cm,height=2cm]
+     {overprint\\\startknockout knockout\stopknockout}%
+   \startknockout
+   \framed
+     [background=color,backgroundcolor=omagenta,
+      foregroundcolor=oyellow,align={lohi,middle},
+      frame=off,width=2.5cm,height=2cm]
+     {knockout\\\startoverprint overprint\stopoverprint}%
+   \stopknockout}%
+\stopoverprint
+\stopbuffer
+
+\typebuffer[b]
+
+Sometimes the overprint preview in \ACROBAT\ works better when we apply a gray
+background (\in {figure} {c} [fig:overprint]). We use rather ugly pure \CMYK\
+colors, otherwise the effect is not visible in overprint preview mode.
+
+\startbuffer[c]
+\framed
+  [background=color,backgroundcolor=ogray,backgroundoffset=.25em,
+   frame=off,offset=overlay]
+  {\getbuffer[a]}
+\stopbuffer
+
+\typebuffer[c]
+
+and (\in {figure} {d} [fig:overprint]):
+
+\startbuffer[d]
+\framed
+  [background=color,backgroundcolor=ogray,backgroundoffset=.25em,
+   frame=off,offset=overlay]
+  {\getbuffer[b]}
+\stopbuffer
+
+\typebuffer[d]
+
+\startbuffer
+\startcombination[2*2]
+  {\getbuffer[a]} {a}
+  {\getbuffer[c]} {c}
+  {\getbuffer[b]} {b}
+  {\getbuffer[d]} {d}
+\stopcombination
+\stopbuffer
+
+\placefigure
+  [here] [fig:overprint]
+  {Preview overprint and knockout.}
+  {\getbuffer}
+
+If we look at examples~b and~d of \in {figure} [fig:overprint]) in \ACROBAT\
+overprint preview mode, we will see that the effect depends on where we apply the
+overprint settings. As said, these are tricky features and should be used with
+care and understanding.

+\startbuffer[abstract]
+    The \type {m-visual} module is used in some manuals that come with \CONTEXT\
+    to generate random text. This is sometimes less confusing that nice quotes
+    because the reader can then distinguish the explanation from the example.
+    This module is not extensive (but may grow) and is just an addition to
+    already built in visualization tools.
+\stopbuffer
+
+\startdocument
+  [title={Faking Text and More},
+   author=Hans Hagen,
+   affiliation=PRAGMA ADE,
+   date=August 2004,
+   number=7 \MKIV]
+
+\setupindenting[medium] \indenting[always] \setupwhitespace[none]
+
+\subject{Remark}
+
+When again a user asked me for the macros that I use to generate fake text, I
+took a while to document them. Most macros use the built in random number
+generator. In manuals you may want to control the randomization a bit. You can do
+that by setting the seed:
+
+\starttyping
+\setupystem[random=12345]
+\stoptyping
+
+% Some more visualization tricks are discussed in the visual debugger modules \type
+% {supp-vis.tex} and \type {core-vis.tex}. If you have special wishes, let me know.
+% If they make sense (or more important: if they can be implemented in a decent
+% way) they may be honored in the future.
+
+In \MKIV\ there is a lot of visualization available like showing all boxes, glue,
+characters etc.\ (try \type {\showmakeup}) . Many mechanism have dedicated
+trackers that visualize matters with color. Here we just mention a few
+possibilities of a module with helpers. This module is loaded with:
+
+\starttyping
+\usemodule[visual]
+\stoptyping
+
+\subject{Faking words}
+
+We don't need much words to demonstrate the macros. Here we fake a single work
+with \type {\fakeword}: \fakeword. You can fake a whole bunch with:
+
+\startbuffer
+\fakewords{100}{200} \par
+\fakewords {30} {80} \par
+\fakewords{200}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+In addition to \type {\fakewords} we have \type {\fakenwords}. This time we don't
+specify a range, but a number and a random seed.
+
+\startbuffer
+\fakenwords{100}{2} % words seed
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Drop caps can be faked as follows:
+
+\startbuffer
+\fakedroppedcaps{3}
+\fakewords{100}{200} \par
+\fakewords{100}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can visualize the indentation by adding another faker:
+
+\startbuffer
+\fakeparindent \fakewords{100}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can suppress indentation with:
+
+\startbuffer
+\onlyfakewords{100}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can influence the color by redefining one or more of the folowing fake
+colors:
+
+\startbuffer
+\definecolor[fakerulecolor]     [black]
+\definecolor[fakebaselinecolor] [green]
+\definecolor[fakeparindentcolor][blue]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+In case you wonder if fake words hyphenate, they kind of do, as is shown here:
+\bgroup \showfakewords \onlyfakewords{100}{200} \egroup
+
+\subject{Faking lines}
+
+Lines can be faked with:
+
+\startbuffer
+\fakelines{3}{5}
+\fakelines{4}{8}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This is (of course) more efficient than faking words.
+
+\subject{Faking figures}
+
+Faking figures does not make that much sense.
+
+\startbuffer
+\fakefigure
+  [left][]
+  {10em}{12em}
+  {3\lineheight}{5\lineheight}
+
+\fakewords{100}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+In this case the width will vary between \type {10em} and \type {12em}, while the
+height end up somewhere between 3 and~5 times the lineheight.
+
+If you want nice placeholders you can better use the \METAPOST\ \type {dum}
+library. This one hooks into the external figure placement macros and will
+produce a random graphic (with more or less random colors).
+
+\startbuffer
+\useMPlibrary[dum]
+\placefigure
+  [left][]
+  {\fakewords{3}{6}}
+  {\externalfigure[ForTheMomentFaked][width=3cm,height=2cm]}
+
+\fakewords{100}{200}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\subject{Faking formulas}
+
+Another probably seldom used placeholder is \type {\fakeformula}:
+
+\startbuffer
+\startformula \fakeformula \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+An alternative, showing baselines, is:
+
+\startbuffer
+\startformula \fakespacingformula \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can trigger drawing of baseline yourself too:
+
+\startbuffer
+\showbaselines
+\fakewords{100}{200} \par
+\fakewords {30} {80} \par
+\fakewords{200}{200}
+\stopbuffer
+
+\typebuffer \bgroup \getbuffer \egroup
+
+In this case you will notice that this document is not typeset on a grid, and
+therefore, since the blank space is set to big the baseline visualization shows
+this distance when applicable.

+\startbuffer[abstract]
+    The content of tenth magazine was written while listening to Tori Amos'
+    latest album, The Beekeeper. In the (nice) booklet the text flows in shapes
+    and here I will demonstrate that \TEX\ can do something similar. It's also a
+    nice example of applying \HZ\ optimization.
+\stopbuffer
+
+\startdocument
+  [title={Good looking shapes},
+   author=Hans Hagen,
+   affiliation=PRAGMA ADE,
+   date=March 2005,
+   number=10 \MKIV]
+
+Just as it takes while to get an understanding what \TEX\ is about, it takes a
+couple of listening loops to get a general picture about Tori Amos' Beekeeper.
+While browsing the rather nicely designed booklet I got puzzled |<|as usual when
+seeing such nice book(let)s|>| why everything looked okay except the text. High
+end design combined with rather low end typography. Don't get me wrong, apart
+from the typesetting it's a pretty good product! Tori being one of my favourite
+artists, you can imagine that I wrote quite some \CONTEXT\ code listening to her
+music.
+
+Now I will not argue that \TEX\ (or \CONTEXT) is the proper system for making
+\CD\ covers, but since most of such a booklet is a matter of pasting graphics
+components together, I can imagine that one should ask someone to typeset the
+text snippets using a proper engine. Anyway, most buyers (fans) won't notice it,
+but anyone familiar with \TEX\ will immediate get distracted by the strange
+intercharacter and interline spacing.
+
+Typesetting in a fixed shape is non||trivial. First of all lines should break in
+a pleasing way. If possible, hyphenation should be avoided. The gaps between
+characters must not become to large and the last line should not be too short.
+Doing this in \TEX\ is non trivial either, not so much because \TEX\ cannot do
+such things, but because one needs to control several mechanisms at once. On the
+other hand, one should know what one's dealing with anyway.
+
+Because the size of the shape is fixed, we can manipulate the number of lines
+and/or the line length and scale afterwards to the desired size. The font size is
+not fixed. This permits us to implement a semi||automated solution. The
+difference between the first version of the solution and current one is that we
+take into account an odd|/|even number of lines. Also, finding the best exit
+condition took some experiments. The final solution is not that complex and also
+shows a couple of tricks.

+
+Normally one will not put a shape behind the text, but in our case it illustrates
+the idea. We use an offset in order to get a more pleasing look.

+
+Now comes the dirty code. We assume that you know a bit of \CONTEXT. First of all
+we choose a font, in our case a Termes for the running text. We will use
+Hermann Zapf optimization, which is way more acceptable that intercharacter
+spacing and gives quite good results here.
+
+\startbuffer
+\definefontfeature[hzdefault][default][hz=quality]
+\definefont[BeeFont][file:texgyre-termes*hzdefault]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The core of the code is a loop wherein we try to figure out what the best width
+is. In principle this method can be used for similar shapes. Beforehand we define
+a few variables.
+
+\startbuffer
+\cldcontext{math.cosd(60)}
+\cldcontext{math.sind(60)}
+
+\newdimen\BeeEdge
+\newdimen\BeeLine
+\newdimen\BeeSize
+
+\newbox  \BeeBox
+
+\def\BeeLines{17}   % choose optimum odd/even
+\def\BeeStart{2cm}  % set automatically
+\def\BeeStep {.5mm} % accurate enough
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The loop starts with a rather small width and with increasing steps tries to find
+the solution where the number of used lines equals the asked number of lines. We
+could have used low level \TEX\ primitives, but using a few \CONTEXT\ wrappers
+makes more sense because that way struts and alike are set as well. In the end we
+stretch the interline spacing to match the height of the cell.

+
+This solution is rather safe and, at the cost of the ugly saving of the number of
+lines as registered in \type {\prevgraf}, works better than measuring the height
+of the box.
+
+We could build the loop out of more isolated pieces of code like this but the
+reason why we do it for the checker is that we now can redefine it. At the cost
+of a few more tests, the following checker is better, because it goes on for a
+while and keeps looking for better solutions. If you have no idea what badness
+is, just skip the following code snippet.
+
+\startbuffer
+\def\CheckBeeLines

+     \fi\fi
+   \else
+     \donetrue
+   \fi\fi}
+\stopbuffer
+
+\getbuffer \typebuffer
+
+Well, this is not the kind of code you want a designer to enter, but providing it
+as feature in a desk top publishing application is also non||trivial because each
+case differs and turning many knobs to get things done is not easy either, so
+basically it comes down to manual work (neglectable to the total amount of work
+involved in getting such a musical product done). Of course one can ask someone
+to typeset the text in \TEX\ and provide it as image, but that would make
+coordination the production more complex.
+
+The criterium (here \BeeStep) can be made smaller when you encounter problems. If
+we set it to 1mm, we get one case where the amount of lines jumps~2 and the loop
+is exit unexpected. Of course one can catch such cases but it does not make much
+sense in such a one||shot macro.
+
+The previous setup is applied as follows:
+
+\startbuffer
+\startsetups beeloner
+  \framed
+    [offset=overlay,
+     frame=off,
+     background=beecell,
+     foregroundstyle=\BeeFont]
+    {\setups[beeloop]}
+\stopsetups
+\stopbuffer
+
+\getbuffer \typebuffer
+
+We will now put several variants alongside. For this we use a layer:

+   height=9cm]

+
+The first samples, shown in \in {figure} [fig:parasol], will be typeset using:
+
+\typebuffer[a]
+
+The second example, shown in \in {figure} [fig:beekeeper], is done in a similar
+way. We redefine the \type {beetext} setup.
+
+\typebuffer[b]
+
+You can zoom in on cells using your viewer. An enlarged example is shown in \in

+  {The Beekeeper}
+\stopcombination
+\stopbuffer
+
+\typebuffer
+
+Choosing the best alternative is a matter of taste. If you ever get a change to
+see the \CD\ (a good buy anyway) you will note the difference. It is possible to

+The downside of this exercise was that in the process my laptop suddenly made

+message may be not to bother too much about badly typeset paragraphs in \CD\
+booklets.

+
+\startbuffer[abstract]
+    For a long time already \CONTEXT\ provides a way to organize your document(s)
+    in a structure that permits processing of components. This mechanism has been
+    upgraded a bit in \MKIV\ and here we will summarize the status quo.
+\stopbuffer
+
+\startdocument
+  [title={Project Structure},
+   author=Hans Hagen,
+   affiliation=PRAGMA ADE,
+   date=July 2011,
+   number=1101 \MKIV]
+
+A regular document has a simple structure. When we talk about structure here, we
+only refer to the overall document structure.
+
+\startscite[tex]
+% style specification
+
+\starttext
+  % the document content
+\stoptext
+\stopscite
+
+For practical reasons we delay initial font loading till the first \type
+{\starttext} so that one can overload the defaults. This means that when no
+bodyfont is specified, and {\starttext} is not given, there will be hardly any
+visible output.
+
+An example of a more elaborate structure is the following:
+
+% \enabletrackers[context.trace]
+
+\startscite[tex]
+\environment environment-1
+\environment environment-2
+
+\startproduct product-1
+
+  \component component-1.tex
+  \component component-2.mkiv
+  \component component-3.cld
+
+  \component component-1
+  \component component-2
+
+\stopproduct
+\stopscite
+
+Here we have a specific product, made up out of components and using a few
+environment files that specify the style. By default we assume tex files, but you
+can be specific and use known suffixes. A less abstract example is the following:
+
+\startscite[tex]
+\environment my-fonts
+\environment my-style
+\environment my-abbreviations
+\environment my-urls
+
+\startproduct manual
+
+  \component titlepage
+  \component contents
+
+  \component chapter-1
+  \component chapter-2
+  \component chapter-3
+
+  \component index
+
+\stopproduct
+\stopscite
+
+You can process components and products independently but be aware that you won't
+get cross document (or chapter) references then.
+
+There is one more level: projects.
+
+\startscite[tex]
+\environment my-fonts
+\environment my-style
+\environment my-abbreviations
+\environment my-urls
+
+\startproject documentation
+
+  \product manual
+  \product faqs
+
+\stopproject
+\stopscite
+
+This means that we can also define the manual as follows:
+
+\startscite[tex]
+\project documentation
+
+\startproduct manual
+
+  \component titlepage
+  \component contents
+
+  \component chapter-1
+  \component chapter-2
+  \component chapter-3
+
+  \component index
+
+\stopproduct
+\stopscite
+
+Environments are only loaded once and when you run a component or product that
+refers to environments or when environments are picked up from an encapsulating
+structure you need to be aware of the order of loading.
+
+The names given after the start command are not that important but the names
+after the simple commands refer to filenames, so in the next case there need to
+be a file called \type {index.tex}:
+
+\startscite[tex]
+\component index
+\stopscite
+
+Equally valid is:
+
+\startscite[tex]
+\component[index]
+\stopscite
+
+Subpaths are also permitted:
+
+\startscite[tex]
+\component manual/index
+\stopscite
+
+The meaning of the mentioned commands is not frozen but adapts itself to the
+current situation. A file can be processed many times, only once or never. The
+following table shows what will happen when:
+
+\ctxlua{moduledata.jobs.showprocessors()}
+
+When you load an environment or component, you can specify it to be a \LUA\ file
+by using the \type {lua} or \type {cld} suffix. In that case the file will be
+loaded in the right way. From the table you can deduce that the following is also
+valid:
+
+\startscite[tex]
+\environment mystyle
+
+\starttext
+  % the content
+\stoptext
+\stopscite
+
+combined with:
+
+\startscite[tex]
+\startenvironment mystyle
+  % the definitions
+\stopenvironment
+\stopscite
+
+This is about the simplest structure that you can use that still gives a bit of
+abstraction.
+
+In addition to files in a project structure, you can load predefined modules.
+
+\startscite[tex]
+\usemodule[mathml]
+\stopscite
+
+or more specific:
+
+\startscite[tex]
+\usemodule[x][mathml]
+\stopscite
+
+Which limits the lookup to the \type {x} namespace. The first match quits the
+search and the order of lookups is: \type {mkvi}, \type {mkiv}, \type {tex},
+\type {cld}, \type {lua}. It follows that modules can be \LUA\ files.
+
+When you use structure in the files you will find an overview in the log file.
+This looks as follows:
+
+\starttyping
+system          > structure > start used structure
+
+used structure  > text: product-1
+used structure  >   environment: environment-1
+used structure  >   environment: environment-2
+used structure  >   product: product-1
+used structure  >     component: component-1
+used structure  >     component: component-2
+used structure  >     component: component-1
+used structure  >     component: component-2
+
+system          > structure > stop used structure
+\stoptyping
+
+Some basic logging on the console can be enabled with:
+
+\startscite[tex]
+\enabletrackers[system.jobfiles]
+\stopscite
+
+A new command pair is the following:
+
+\starttyping
+\startdocument[settings]
+    structured content
+\stopdocument
+\stoptyping
+
+The settings are key|/|value pairs and the values can be retrieved using:
+
+\starttyping
+\documentvariable{key}
+\stoptyping
+
+You can set \type {before} and \type {after} parameters and by default these are
+set up as follows:
+
+\starttyping
+\setvariables
+  [document]
+  [before=\directsetup{document:start},
+   after=\directsetup{document:stop}]
+\stoptyping
+
+You can for instance define these setups to generate a title page (using document
+variables) and a colophon page. In the future more functionality might be added.

+    A not so widely known feature of the verbatim handler in \CONTEXT\ is the
+    ability to add comments in another style and \MKIV\ even offers a bit more.
+    Here some examples are shown.
+\stopbuffer

+\startdocument

+Annotating verbatim content is done using a mechanism called escaping. For such
+special cases it's often best to define a specific instance.
+
+\startbuffer[define]
+\definetyping
+  [annotatedtyping]
+  [escape=/,
+   color=darkblue,
+   before=,
+   after=]
+\stopbuffer
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               /bgroup /sl oeps /egroup
+                         /bgroup /bf some more /egroup
+    | another test
+    | somethingverylong  /bgroup /it oeps /egroup
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[define,example][option=TEX] \getbuffer[define]
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+In this example the \type {/} now serves as an escape character. Of course you
+can also use the normal backslash but then you need to use a command to specify
+it.
+
+\startbuffer[setup]
+\setuptyping
+  [annotatedtyping]
+  [escape=\letterbackslash]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+Now we can say:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               \bgroup \sl oeps \egroup
+                         \bgroup \bf some more \egroup
+    | another test
+    | somethingverylong  \bgroup \it oeps \egroup
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+and get:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+You can also define an end symbol:
+
+\startbuffer[setup]
+\setuptyping
+  [annotatedtyping]
+  [escape={//,*},
+   color=darkblue]
+
+\definestartstop
+  [cmt]
+  [style=\rm\bf]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+Here the \type {//} starts the annotation and \type {*} ends it.
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               // \black // \cmt{oeps} *
+                         // \black // \cmt{some more} *
+    | another test
+    | somethingverylong  // \black // \cmt{oeps} *
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+Contrary to the first example, all text in the annotation is treated as \TEX\
+input:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+You can consider using more balanced tagging, as in:
+
+\startbuffer[setup]
+\setuptyping
+  [annotatedtyping]
+  [escape={<<,>>},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+Watch how we limit the annotation to part of the text:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               << \rm\bf first  >> test
+                         << \rm\bf second >> test
+    | test
+    | somethingverylong  << \rm\bf fourth >> test
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+The \type {test} a the end of the lines is verbatim again.
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+If no end symbol is given, the end of the line is used instead:
+
+\startbuffer[setup]
+\setuptyping
+  [annotatedtyping]
+  [escape={//,},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+Watch out: here we use \type {{//,}} and not just \type {//} (which would trigger
+the escaped variant).
+
+\definestartstop[cmt][style=\rm\bf]
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               // \black // \cmt{oeps}
+                         // \black // \cmt{some more}
+    | test
+    | somethingverylong  // \black // \cmt{oeps}
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+The result is:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+This can also be done easier by abusing the \type {style} option of \type {cmt}:
+
+\startbuffer[setup]
+\definestartstop
+  [cmt]
+  [color=black,
+   style=\black //\rm\bf\space]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+When we give:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               // \cmt{oeps}
+                         // \cmt{some more}
+    | test
+    | somethingverylong  // \cmt{oeps}
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+We get:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+For cases like this, where we want to specify a somewhat detailed way to deal
+with a situation, we can use processors: \footnote {More mechanisms in \CONTEXT\
+\MKIV\ will use that feature.}
+
+\startbuffer[setup]
+\defineprocessor
+  [escape]
+  [style=bold,
+   color=black,
+   left=(,right=)]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+The previous definition of the annotation now becomes:
+
+\startbuffer[setup]
+\setuptyping
+  [annotatedtyping]
+  [escape=escape->{//,},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+This time no commands are needed in the annotation:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               // first
+                         // second
+    | test
+    | somethingverylong  // fourth
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+The processor is applied to all text following the \type {//}. Spaces before the
+text are stripped.
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+As some characters are special to \TEX, sometimes you need to escape the boundary
+sequence:
+
+\startbuffer[setup]
+\defineprocessor
+  [myescape]
+  [style=\rm\tf,
+   color=black]
+
+\setuptyping
+  [annotatedtyping]
+  [escape=myescape->{\letterhash\letterhash,},
+   color=darkgreen]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+All text between the double hashes and the end of the line is now treated as
+annotation:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               ## first \bf test
+                         ## second \sl test
+    | test
+    | somethingverylong  ## third \it test
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+So we get:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+We can beautify \TEX\ commenting as follows:
+
+\startbuffer[setup]
+\defineprocessor
+  [comment]
+  [style=\rm,
+   color=black,
+   left={\tttf\letterpercent\space}]
+
+\setuptyping
+  [annotatedtyping]
+  [escape=comment->{\letterpercent\letterpercent,},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+Here the double comments are turned into a single one and the text after it is
+typeset in a regular font:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               %% first \bf test
+                         %% second \sl test
+    | test
+    | somethingverylong  %% third \it test
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+This gives:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+It is possible to define several escapes. Let's start with the delimited variant:
+
+\startbuffer[setup]
+\defineprocessor
+  [escape_a]
+  [style=bold,
+   color=darkred,
+   left=(,
+   right=)]
+
+\defineprocessor
+  [escape_b]
+  [style=bold,
+   color=darkgreen,
+   left=(,
+   right=)]
+
+\setuptyping
+  [annotatedtyping]
+  [escape={escape_a->{[[,]]},escape_b->{[(,)]}},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+We can now alternate comments:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               [[ first  ]] test [( first  )]
+                         [[ second ]] test [( second )]
+    | test
+    | somethingverylong  [[ fourth ]] test [( fourth )]
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+When typeset this looks as follows:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+
+The line terminated variant can also have multiple escapes.
+
+\startbuffer[setup]
+\defineprocessor
+  [annotated_bf]
+  [style=\rm\bf,
+   color=darkred]
+
+\defineprocessor
+  [annotated_bs]
+  [style=\rm\bs,
+   color=darkyellow]
+
+\setuptyping
+  [annotatedtyping]
+  [escape={annotated_bf->{!bf,},annotated_bs->{!bs,}},
+   color=darkblue]
+\stopbuffer
+
+\typebuffer[setup][option=TEX] \getbuffer[setup]
+
+So this time we have two ways to enter regular \TEX\ mode:
+
+\startbuffer[example]
+\startannotatedtyping
+bla = test               !bf one {\em again}
+                         !bs two {\em again}
+    | test
+    | somethingverylong  !bf three {\em again}
+\stopannotatedtyping
+\stopbuffer
+
+\typebuffer[example][option=TEX]
+
+These somewhat meaningful tags result in:
+
+\starttextbackground[example]
+    \getbuffer[example]
+\stoptextbackground
+

+\usemodule[mag-01,abr-02]
+
+\startbuffer[abstract]
+    The (cross) reference mechanism in \CONTEXT\ is rather complex (in terms of
+    code) and provides a lot of functionality. Of course one can ask for page
+    numbers, section numbers, titles, or arbitrary text, but also control the
+    viewer, go to locations and have chains of actions. In this document we only
+    discuss some aspects of cross document referencing. This is not a complete
+    manual.
+\stopbuffer
+
+\startdocument
+  [title={Cross document referencing},
+   author=Hans Hagen,
+   affiliation=PRAGMA ADE,
+   date=September 2011,
+   number=1103 \MKIV]
+
+\subject{Other documents}
+
+A straightforward way to refer to something in an other document is by prefixing
+the reference by a document tag. Take for instance:
+
+\startscite[tex]
+\in{chapter}[other::whatever]
+\stopscite
+
+Here, \type {other} is either a tag or a filename. In the case if a tag, you also
+need a definition like:
+
+\startscite[tex]
+\useexternalfile[other][somefilename]
+\stopscite
+
+Because we load the references of the other file (when present), you can also ask
+for titles of chapters. In fact, all the following work:
+
+\startscite[tex]
+\at      {page}[other::whatever]
+\in   {chapter}[other::whatever]
+\about         [other::whatever]
+\goto{location}[other::whatever]
+\stopscite
+
+given of course that in the other file we have set a reference:
+
+\startscite[tex]
+\startchapter[reference=whatever,title={Who cares}]
+  ...
+\stopchapter
+\stopscite
+
+In \MKIV\ this mechanisms has been extended to deal with products and components.
+In order not to get clashes between references in multiple chapters, you can do
+something like this:
+
+\startscite[tex]
+\setuphead[chapter][referenceprefix=whatever]
+\stopscite
+
+This will create a namespace for this chapter. A more automated alternative is:
+
+\startscite[tex]
+\setuphead[chapter][referenceprefix=+]
+\stopscite
+
+Here the given reference (\type {whatever}) will automatically become the
+namespace for that chapter.
+
+\subject{Products and components}
+
+This is however somewhat cumbersome when we deal with a project structure. There
+we have the complication that we can process components within a product and
+although one will only do this for proofing it makes sense at least to deal with
+references in other components.
+
+In the test suite there are four files demonstrating what is possible. They can
+be recognized by the name \type {cross-*.tex}. The product file \type {cross-100}
+includes two components:
+
+\startscite[tex]
+\startproduct cross-100
+
+    \component cross-001
+    \component cross-002
+
+\stopproduct
+\stopscite
+
+In these components there are references to the other component. The cross
+reference mechanism will automatically use the component's name as namespace but
+only when you say:
+
+\startscite[tex]
+\setupreferencing[autofile=yes]
+\stopscite
+
+A component looks as follows:
+
+\startscite[tex]
+\setupreferencing[autofile=yes]
+\setupinteraction[state=start]
+
+\startcomponent cross-001
+
+\product cross-100
+
+\startchapter[title=One,reference=one]
+  ...
+\stopchapter
+
+\stopcomponent
+\stopscite
+
+When a component is processed, the references of the product are also loaded.
+Actually, some more information fetched so that for instance the chapter number
+gets set as well as the page number.
+
+Of course this will not guarantee that all referencing turns out right, but it's
+better than nothing. There are now several ways to refer to something, and as we
+have quite some fallback heuristics in place all the following will work out
+well. However, keep in mind that when multiple \type {one}'s are uses you might
+end up with the wrong one when no prefix is given.
+
+\startscite[tex]
+\at      {page}[one]
+\in   {chapter}[one]
+\about         [one]
+\goto{location}[one]
+
+\at      {page}[cross-001:one]
+\in   {chapter}[cross-001:one]
+\about         [cross-001:one]
+\goto{location}[cross-001:one]
+
+\at      {page}[cross-001::one]
+\in   {chapter}[cross-001::one]
+\about         [cross-001::one]
+\goto{location}[cross-001::one]
+
+\at      {page}[cross-001:::one]
+\in   {chapter}[cross-001:::one]
+\about         [cross-001:::one]
+\goto{location}[cross-001:::one]
+\stopscite
+
+So what do the (subtle) differences in colons mean? The \type {cross-001:} prefix
+is just a prefix. Such a prefix is not always related to a document but it
+happens that when no other match is found, an extra check takes place to see if
+it is a component namespace. This is new per September 2011.
+
+The \type {cross-001::} prefix is the official way to refer to another document
+and this is no news. However, the \type {cross-001:::} prefix is new and
+depending on how the document is run, is either a regular namespace prefix (one
+colon) or an external reference (two colons). When you use the project structure
+this might be the best way to go. The reason is that order of looking (and
+fallbacks) is better defined this way.
+
+So, given that you have a proper usage of product and components, the following
+method is to be preferred:
+
+\startscite[tex]
+\at     {page}[other:::one] in \from[other]
+\in   chapter}[other:::one] of \from[other] (\about[other:::one])
+\goto{details}[other:::one]
+\stopscite
+
+Keep in mind that in most cases a combination of components and extra prefixes
+(that is, explicitly set prefixes) work ok. The prefixing mechanism is controlled
+with:
+
+\startscite[tex]
+\setupreferencing[prefix=blabla]
+\stopscite
+
+but you will seldom need this command. In order to prevent clashes you can best
+use some redundancy:
+
+\startscite[tex]
+\placefigure[here][fig:foo]{}{}{}
+\placetable [here][tab:foo]{}{}{}
+\stopscite
+
+works out quite well.
+
+\subject{Reference commands}
+
+In \MKII\ the main reference mechanism handled not only user references but also
+stored section numbers, section titles, captions and all that made sense to refer
+to. In \MKIV\ we carry around way more information and references are stored in
+and retrieved from several data structures. Although we keep much more
+information in memory and store more information in the auxiliary file, we save
+some too because now (for instance) section titles are stored only once.
+
+The following two commands store an explicit reference, unrelated to a structural
+component. However, with the page number we also store information about the
+current section so that we can add a prefix any time we want.
+
+\startscite[tex]
+\textreference[sometag]{some text}
+\pagereference[sometag]
+\stopscite
+
+Keep in mind that these commands insert a so called node so they can best be
+attached to some content in order not to dangle around and interfere with
+spacing. The following works okay:
+
+\startscite[tex]
+\dontleavehmode\textreference[ward]{Quoting Ward}\input ward
+\stopscite
+
+A rather low level (not interactive) fetching can be done as follows:
+
+\startscite[tex]
+\ref[text][sometag]
+\ref[page][sometag]
+\stopscite
+
+We already saw some more advanced commands to retrieve reference data:
+
+\startscite[tex]
+\at      {page}[one]
+\in   {chapter}[one]
+\about         [one]
+\goto{location}[one]
+\stopscite
+
+These commands will create a hyperlink when interactivity is turned on.
+
+The \type {\at} command typesets the page number and the \type {\in} command
+typesets a number. The \type {\about} command deals with the title. In the case
+of a regular reference the last two commands do a similar thing but the last one
+adds quotes (by default). The \type {\goto} command only has a meaning in
+interactive documents. It does not add anything to the text.
+
+In interactive mode all these commands will apply a so called contrast color in
+case the reference refers to the page itself.
+
+There are two commands that relate to current location:
+
+\startscite[tex]
+\somewere{before}{current}{after}[one]
+\atpage[one]
+\stopscite
+
+The first command typesets one of the three texts, which one depends of the
+typeset and referred \type {one} being on the same page. The second command
+generates a text automatically.
+
+Although not related to the kind of references we discuss here, you can define
+symbolic references with:
+
+\startscite[tex]
+\definereference[symbolic name][real reference]
+\resetreference[symbolic name]
+\stopscite
+
+Using this only makes sense in interactive documents where we can have special
+operations with arguments and combinations of such references.
+
+\subject{Reference formats}
+
+You can control the formatting of references in detail using the setup command.
+For instance you can tweak the way sections numbers are prefixed but as this
+relates to numbering this will not be discussed here. Reference formats are
+another way to control the rendering
+
+\startscite[tex]
+\definereferenceformat[informula]  [left=(,right=),text=formula]
+\definereferenceformat[informulas] [left=(,right=),text=formulas]
+\definereferenceformat[andformula] [left=(,right=),text=and]
+\definereferenceformat[andformulas][left=(,right=),text=and]
+
+\informula [b] and \informula [for:c]
+the \informula {formulas}[b] \informula {and} [for:c]
+the \informulas {formulas}[b] \informula {and} [for:c]
+the \informulas [b] \informula {en} [for:c]
+the \informulas [b] \andformula [for:c]
+\stopscite
+
+Instead of a text, one can specify a label, which should be defined with \type
+{\setuplabeltext}.
+
+\subject{User references}
+
+You can create user references too. This is done with the following command:
+
+\startscite[tex]
+\setreference[myref][key-1=value-1,key-2=value-2]
+\stopscite
+
+You can then ask for keys using:
+
+\startscite[tex]
+\getreference[myref][key-2]
+\stopscite
+
+In principle you can add filters and rendering variants as well using \LUA\ code
+but that is rather specialized and often not needed.

+\startchapter[title={Calling Lua}]
+
+\startsection[title=Introduction]
+
+One evening, on Skype, Luigi and I were pondering about the somewhat
+disappointing impact of jit in \LUAJITTEX\ and one of the reasons we could come
+up with is that when you invoke \LUA\ from inside \TEX\ each \type {\directlua}
+gets an extensive treatment. Take the following:
+
+\starttyping
+\def\SomeValue#1%
+  {\directlua{tex.print(math.sin(#1)/math.cos(2*#1))}}
+\stoptyping
+
+Each time \type {\SomeValue} is expanded, the \TEX\ parser will do the following:
+
+\startitemize[packed]
+\startitem
+    It sees \type {\directlua} and will jump to the related scanner.
+\stopitem
+\startitem
+    There it will see a \type +{+ and enter a special mode in which it starts
+    collecting tokens.
+\stopitem
+\startitem
+    In the process, it will expand control sequences that are expandable.
+\stopitem
+\startitem
+    The scanning ends when a matching \type +}+ is seen.
+\stopitem
+\startitem
+    The collected tokens are converted into a regular (C) string.
+\stopitem
+\startitem
+    This string is passed to the \type {lua_load} function that compiles it into
+    bytecode.
+\stopitem
+\startitem
+    The bytecode is executed and characters that are printed to \TEX\ are
+    injected into the input buffer.
+\stopitem
+\stopitemize
+
+In the process, some state information is set and reset and errors are dealt
+with. Although it looks like a lot of actions, this all happens very fast, so
+fast actually that for regular usage you don't need to bother about it.
+
+There are however applications where you might want to see a performance boost,
+for instance when you're crunching numbers that end up in tables or graphics
+while processing the document. Again, this is not that typical for jobs, but with
+the availability of \LUA\ more of that kind of usage will show up. And, as we now
+also have \LUAJITTEX\ its jitting capabilities could be an advantage.
+
+Back to the example: there are two calls to functions there and apart from the
+fact that they need to be resolved in the \type {math} table, they also are
+executed C functions. As \LUAJIT\ optimizes known functions like this, there can
+be a potential speed gain but as \type {\directlua} is parsed and loaded each
+time, the jit machinery will not do that, unless the same code gets exercised
+lots of time. In fact, the jit related overhead would be a waste in this one time
+usage.
+
+In the next sections we will show two variants that follow a different approach
+and as a consequence can speed up a bit. But, be warned: the impact is not as
+large as you might expect, and as the code might look less intuitive, the good
+old \type {\directlua} command is still the advised method.
+
+Before we move on it's important to realize that a \type {\directlua} call is
+in fact a function call. Say that we have this:
+
+\starttyping
+\def\SomeValue{1.23}
+\stoptyping
+
+This becomes:
+
+\starttyping
+\directlua{tex.print(math.sin(1.23)/math.cos(2*1.23))}
+\stoptyping
+
+Which in \LUA\ is wrapped up as:
+
+\starttyping
+function()
+    tex.print(math.sin(1.23)/math.cos(2*1.23))
+end
+\stoptyping
+
+that gets executed. So, the code is always wrapped in a function. Being a
+function it is also a closure and therefore local variables are local to this
+function and are invisible at the outer level.
+
+\stopsection
+
+\startsection[title=Indirect \LUA]
+
+The first variant is tagged as indirect \LUA. With indirect we mean that instead
+of directly parsing, compiling and executing the code, it is done in steps. This
+method is not as generic a the one discussed in the next section, but for cases
+where relatively constant calls are used it is fine. Consider the next call:
+
+\starttyping
+\def\NextValue
+  {\indirectlua{myfunctions.nextvalue()}}
+\stoptyping
+
+This macro does not pass values and always looks the same. Of course there can be
+much more code, for instance the following is equally valid:
+
+\starttyping
+\def\MoreValues {\indirectlua{
+    for i=1,100 do
+        myfunctions.nextvalue(i)
+    end
+}}
+\stoptyping
+
+Again, there is no variable information passed from \TEX. Even the next variant
+is relative constant:
+
+\starttyping
+\def\SomeValues#1{\indirectlua{
+    for i=1,#1 do
+        myfunctions.nextvalue(i)
+    end
+}}
+\stoptyping
+
+especially when this macro is called many times with the same value. So how does
+\type {\indirectlua} work? Well, it's behaviour is in fact undefined! It does,
+like \type {\directlua}, parse the argument and makes the string, but instead of
+calling \LUA\ directly, it will pass the string to a \LUA\ function \type
+{lua_call}.
+
+\starttyping
+lua.call = function(s) load(s)() end
+\stoptyping
+
+The previous definition is quite okay and in fact makes \type {\indirectlua}
+behave like \type {\directlua}. This definition makes
+
+% \ctxlua{lua.savedcall = lua.call lua.call = function(s) load(s)() end}
+% \testfeatureonce{10000}{\directlua  {math.sin(1.23)}}
+% \testfeatureonce{10000}{\indirectlua{math.sin(1.23)}}
+% \ctxlua{lua.call = lua.savedcall}
+
+\starttyping
+\directlua  {tex.print(math.sin(1.23))}
+\indirectlua{tex.print(math.sin(1.23))}
+\stoptyping
+
+equivalent calls but the second one is slightly slower, which is to be expected
+due to the wrapping and indirect loading. But look at this:
+
+\starttyping
+local indirectcalls = { }
+
+function lua.call(code)
+    local fun = indirectcalls[code]
+    if not fun then
+        fun = load(code)
+        if type(fun) ~= "function" then
+            fun = function() end
+        end
+        indirectcalls[code] = fun
+    end
+    fun()
+end
+\stoptyping
+
+This time the code needs about one third of the runtime. How much we gain depends
+on the size of the code and its complexity, but on the average its's much faster.
+Of course, during a \TEX\ job only a small part of the time is spent on this, so
+the overall impact is much smaller, but it makes runtime number crunching more
+feasible.
+
+If we bring jit into the picture, the situation becomes somewhat more diffuse.
+When we use \LUAJITTEX\ the whole job processed faster, also this part, but
+because loading and interpreting is more optimized the impact might be less. If
+you enable jit, in most cases a run is slower than normal. But as soon as you
+have millions of calls to e.g.\ type {math.sin} it might make a difference.
+
+This variant of calling \LUA\ is quite intuitive and also permits us to implement
+specific solutions because the \type {lua.call} function can be defined as you
+with. Of course macro package writers can decide to use this feature too, so you
+need to beware of unpleasant side effects if you redefine this function.
+
+% \testfeatureonce{100000}{\directlua  {math.sin(1.23)}}
+% \testfeatureonce{100000}{\indirectlua{math.sin(1.23)}}
+
+\stopsection
+
+\startsection[title=Calling \LUA]
+
+In the process we did some tests with indirect calls in \CONTEXT\ core code and
+indeed some gain in speed could be noticed. However, many calls get variable
+input and therefore don't qualify. Also, as a mixture of \type {\directlua} and
+\type {\indirectlua} calls in the source can be confusing it only makes sense to
+use this feature in real time|-|critical cases, because even in moderately
+complex documents there are not that many calls anyway.
+
+The next method uses a slightly different approach. Here we stay at the \TEX\
+end, parse some basic type arguments, push them on the \LUA\ stack, and call a
+predefined function. The amount of parsing \TEX\ code is not less, but especially
+when we pass numbers stored in registers, no tokenization (serialization of a
+number value into the input stream) and stringification (converting the tokens
+back to a \LUA\ number) takes place.
+
+\starttyping
+\indirectluacall 123
+    {some string}
+    \scratchcounter
+    {another string}
+    true
+    \dimexpr 10pt\relax
+\relax
+\stoptyping
+
+Actually, an extension like this had been on the agenda for a while, but never
+really got much priority. The first number is a reference to a function to be
+called.
+
+\starttyping
+lua.calls = lua.calls or { }
+lua.calls[123] = function(s1,n1,s2,b,n2)
+    -- do something with
+    --
+    -- string  s1
+    -- number  n1
+    -- string  s2
+    -- boolean b
+    -- number  n2
+end
+\stoptyping
+
+The first number to \type {indirectluacall} is mandate. It can best also be a
+number that has a function associated in the \type {lua.calls} table. Following
+that number and before the also mandate \type {\relax}, there can be any number
+of arguments: strings, numbers and booleans.
+
+Anything surrounded by \type {{}} becomes a string. The keywords \type {true} and
+\type {false} become boolean values. Spaces are skipped and everything else is
+assumed to be a number. This means that if you omit the final \type {\relax}, you
+get a error message mentioning a \quote {missing number}. The normal number
+parser applies, so when a dimension register is passed, it is turned into a
+number. The example shows that wrapping a more verbose dimension into a \type
+{\dimexpr} also works.
+
+Performance wise, each string goes from list of tokens to temporary C string to
+\LUA\ string, so that adds some overhead. A number is more efficient, especially
+when you pass it using a register. The booleans are simple sequences of character
+tokens so they are relatively efficient too. Because \LUA\ functions accept an
+arbitrary number of arguments, you can provide as many as you like, or even less
+than the function expects: it is all driven by the final \type {\relax}.
+
+An important characteristic of this kind of call is that there is no \type {load}
+involved, which means that the functions in \type {lua.calls} can be subjected to
+jitting.
+
+\stopsection
+
+\startsection[title=Name spaces]
+
+As with \type {\indirectlua} there is a potential clash when users mess with the
+\type {lua.calls} table without taking the macro package usage into account. It not
+that complex to define a variant that provides namespaces:
+
+\starttyping
+\newcount\indirectmain \indirectmain=1
+\newcount\indirectuser \indirectuser=2
+
+\indirectluacall \indirectmain
+    {function 1}
+    {some string}
+\relax
+
+\indirectluacall \indirectuser
+    {function 1}
+    {some string}
+\relax
+\stoptyping
+
+A matching implementation is this:
+
+\starttyping
+lua.calls = lua.calls or { }
+
+local main = { }
+
+lua.calls[1] = function(name,...)
+    main[name](...)
+end
+
+main["function 1"] = function(a,b,c)
+    -- do something with a,b,c
+end
+
+local user = { }
+
+lua.calls[2] = function(name,...)
+    user[name](...)
+end
+
+user["function 1"] = function(a,b,c)
+    -- do something with a,b,c
+end
+\stoptyping
+
+Of course this is also ok:
+
+\starttyping
+\indirectluacall \indirectmain 1
+    {some string}
+\relax
+
+\indirectluacall \indirectuser 1
+    {some string}
+\relax
+\stoptyping
+
+with:
+
+\starttyping
+main[1] = function(a,b,c)
+    -- do something with a,b,c
+end
+
+user[1] = function(a,b,c)
+    -- do something with a,b,c
+end
+\stoptyping
+
+Normally a macro package, if it wants to expose this mechanism, will provide a
+more abstract interface that hides the implementation details. In that case the
+user is not supposed to touch \type {lua.calls} but this is not much different
+from the limitations in redefining primitives, so users can learn to live with
+this.
+
+\stopsection
+
+\startsection[title=Practice]
+
+There are some limitations. For instance in \CONTEXT\ we often pass tables and
+this is not implemented. Providing a special interface for that is possible but
+does not really help. Often the data passed that way is far from constant, so it
+can as well be parsed by \LUA\ itself, which is quite efficient. We did some
+experiments with the more simple calls and the outcome is somewhat disputable. If
+we replace some of the \quote {critital} calls we can gain some 3\% on a run of
+for instance the \type {fonts-mkiv.pdf} manual and a bit more on the command
+reference \type {cont-en.pdf}. The first manual uses lots of position tracking
+(an unfortunate side effect of using a specific feature that triggers continuous
+tracking) and low level font switches and many of these can benefit from the
+indirect call variant. The command reference manual uses \XML\ processing and
+that involves many calls to the \XML\ mapper and also does quite some string
+manipulations so again there is something to gain there.
+
+The following numbers are just an indication, as only a subset of \type
+{\directlua} calls has been replaced. The 166 page font manual processes in about
+9~seconds which is not bad given its complexity. The timings are on a Dell
+Precision M6700 with Core i7 3840QM, 16 GB memory, a fast SSD and 64 bit Windows
+8. The binaries were cross compiled mingw 32 bit by Luigi. \footnote {While
+testing with several function definitions we noticed that \type {math.random} in
+our binaries made jit twice as slow as normal, while for instance \type
+{math.sin} was 100 times faster. As the font manual uses the random function for
+rendering random punk examples it might have some negative impact. Our experience
+is that binaries compiled with the ms compiler are somewhat faster but as long as
+the engines that we test are compiled similarly the numbers can be compared.}

+So, we can gain some 3\% on such a document and given that we spend probably half
+the time in \LUA, this means that these new features can make \LUA\ run more than
+5\% faster which is not that bad for a couple of lines of extra code. For regular
+documents we can forget about jit which confirms earlier experiments. The

+Here the differences are larger which is due to the fact that we can indirect
+most of the calls used in this processing. The document is rather simple but as
+mentioned is encoded in \XML\ and the \TEX||\XML\ interface qualifies for this
+kind of speedups.
+
+As Luigi is still trying to figure out why jitting doesn't work out so well, we
+also did some tests with (in itself useless) calculations. After all we need
+proof. The first test was a loop with 100.000 step doing a regular \type
+{\directlua}:
+
+\starttyping
+\directlua {
+    local t = { }
+    for i=1,10000
+        do t[i] = math.sin(i/10000)
+    end
+}
+\stoptyping
+
+The second test is a bit optimized. When we use jit this kind of optimizations
+happens automatically for known (!) functions so there is not much won.
+
+\starttyping
+\directlua {
+    local sin = math.sin
+    local t = { }
+    for i=1,10000
+        do t[i] = sin(i/10000)
+    end
+}
+\stoptyping
+
+We also tested this with \type {\indirectlua} and therefore defined some
+functions to test the call variant:
+
+\starttyping
+lua.calls[1] = function()
+    -- overhead
+end
+
+lua.calls[2] = function()
+    local t = { }
+    for i=1,10000 do
+        t[i] = math.sin(i/10000) -- naive
+    end
+end
+
+lua.calls[3] = function()
+    local sin = math.sin
+    local t = { }
+    for i=1,10000 do
+        t[i] = sin(i/10000) -- normal
+    end
+end
+\stoptyping
+
+These are called with:
+
+\starttyping
+\indirectluacall0\relax
+\indirectluacall1\relax
+\indirectluacall2\relax
+\stoptyping
+
+The overhead variant demonstrated that there was hardly any: less than 0.1 second.

+
+The results are somewhat disappoint but not that unexpected. We do see a speedup
+with \LUAJITTEX\ and in this case even jitting makes sense. However in a regular
+typesetting run jitting will never catch up with the costs it carries for the
+overall process. The indirect call is somewhat faster than the direct call.
+Possible reasons are that hashing at the \LUA\ end also costs time and the
+100.000 calls from \TEX\ to \LUA\ is not that big a burden. The indirect call is
+therefore also not much faster because it has some additional parsing overhead at
+the \TEX\ end. That one only speeds up when we pass arguments and even then not
+always the same amount. It is therefore mostly a convenience feature.
+
+We left one aspect out and that is garbage collection. It might be that in large
+runs less loading has a positive impact on collecting garbage. We also need to
+keep in mind that careful application can have some real impact. Take the

+Surprisingly, even jitting helps a bit here. Maybe it relates the the number of
+pages and the amount of calls but we didn't investigate this. By default jitting
+is off anyway. The impact of indirectness is more than in previous examples.
+
+For this test a file was loaded that redefines some core \CONTEXT\ code. This
+also has some overhead which means that numbers for the indirect case will be
+somewhat better if we decide to use these mechanisms in the core code. It is
+tempting to do that but it involves some work and it's always the question if a

+
+When looking at these numbers, keep in mind that it is still not clear if we end
+up using this functionality, and when \CONTEXT\ will use it, it might be in a way
+that gives better or worse timings than mentioned above. For instance, storing \LUA\
+code in the format is possible, but these implementations force us to serialize
+the \type {lua.calls} mechanism and initialize them after format loading. For that
+reason alone, a more native solution is better.
+
+\stopsection
+
+\startsection[title=Exploration]
+
+In the early days of \LUATEX\ Taco and I discussed an approach similar do
+registers which means that there is some \type {\...def} command available. The
+biggest challenge there is to come up with a decent way to define the arguments.
+On the one hand, using a hash syntax is natural to \TEX, but using names is more
+natural to \LUA. So, when we picked up that thread, solutions like this came up
+in a Skype session with Taco:
+
+\starttyping
+\luadef\myfunction#1#2{ tex.print(arg[1]+arg[2]) }
+\stoptyping
+
+The \LUA\ snippet becomes a function with this body:
+
+\starttyping
+local arg = { #1, #2 } -- can be preallocated and reused
+-- the body as defined at the tex end
+tex.print(arg[1]+arg[2])
+\stoptyping
+
+Where \type {arg} is set each time. As we wrapped it in a function we can
+also put the arguments on the stack and use:
+
+\starttyping
+\luadef\myfunction#1#2{ tex.print((select(1,...))+(select(2,...)) }
+\stoptyping
+
+Given that we can make select work this way (either or not by additional
+wrapping). Anyway, both these solutions are ugly and so we need to look further.
+Also, the \type {arg} variant mandates building a table. So, a natural next
+iteration is:
+
+\starttyping
+\luadef\myfunction a b { tex.print(a+b) }
+\stoptyping
+
+Here it becomes already more natural:
+
+\starttyping
+local a = #1
+local b = #2
+-- the body as defined at the tex end
+tex.print(a+b)
+\stoptyping
+
+But, as we don't want to reload the body we need to push \type {#1} into the
+closure. This is a more static definition equivalent:
+
+\starttyping
+local a = select(1,...)
+local b = select(2,...)
+tex.print(a+b)
+\stoptyping
+
+Keep in mind that we are not talking of some template that gets filled in and
+loaded, but about precompiled functions! So, a \type {#1} is not really put there
+but somehow pushed into the closure (we know the stack offsets).
+
+Yet another issue is more direct alias. Say that we define a function at the
+\LUA\ end and want to access it using this kind of interface.
+
+\starttyping
+function foo(a,b)
+    tex.print(a+b)
+end
+\stoptyping
+
+Given that we have something:
+
+\starttyping
+\luadef \myfunctiona a b { tex.print(a+b) }
+\stoptyping
+
+We can consider:
+
+\starttyping
+\luaref \myfunctionb 2 {foo}
+\stoptyping
+
+The explicit number is debatable as it can be interesting to permit
+an arbitrary number of arguments here.
+
+\starttyping
+\myfunctiona{1}{2}
+\myfunctionb{1}{2}
+\stoptyping
+
+So, if we go for:
+
+\starttyping
+\luaref \myfunctionb {foo}
+\stoptyping
+
+we can use \type {\relax} as terminator:
+
+\starttyping
+\myfunctiona{1}{2}
+\myfunctionb{1}{2}\relax
+\stoptyping
+
+In fact, the call method discussed in a previous section can be used here as well
+as it permits less arguments as well as mixed types. Think of this:
+
+\starttyping
+\luadef \myfunctiona a b c { tex.print(a or 0 + b or 0 + c or 0) }
+\luaref \myfunctionb {foo}
+\stoptyping
+
+with
+
+\starttyping
+function foo(a,b,c)

+\startchapter[title=Still Expanding]
+
+In the beginning of October 2013 Luigi figured out that \LUAJITTEX\ could
+actually deal with \UTF\ identifiers. After we played a bit with this, a patch
+was made for stock \LUATEX\ to provide the same. In the process I found out that
+I needed to adapt the \SCITE\ lexer a bit and that some more characters had to
+get catcode~11 (letter). In the following text screendumps from the editor will
+be used instead of verbatim code. This also demonstrates how \SCITE\ deals with
+syntax highlighting.
+
+\starttexdefinition ShowExample #1
+    \startbaselinecorrection
+        \externalfigure[still-expanding-#1][scale=500]
+    \stopbaselinecorrection
+    \getbuffer
+\stoptexdefinition
+
+First we define a proper font for to deal with \CJK\ characters and a helper
+macro that wraps an example using that font.
+
+\startbuffer
+\definefont
+  [GoodForJapanese]
+  [heiseiminstd-w3]
+  [script=kana,
+   language=jan]
+
+\definestartstop
+  [example]
+  [style=GoodForJapanese]
+\stopbuffer
+
+\ShowExample{1}
+
+According to the Google translator, \example {例題} means example and \example
+{数} means number. It doesn't matter much as we only use these characters as
+demo. Of course one can wonder if it makes sense to define functions, variables
+and keys in a script other than basic Latin, but at least it looks kind of
+modern.
+
+\startbuffer
+\startluacode
+    local function 例題(str)
+        context.formatted.example("例題 1.%s: 数 %s",str,str)
+        context.par()
+    end
+
+    for i=1,3 do
+        例題(i)
+    end
+\stopluacode
+\stopbuffer
+
+We only show the first three lines. Because using the formatter gives nicer
+source code we operate in that subnamespace.
+
+\ShowExample{2}
+
+As \CONTEXT\ is already \UTF\ aware for a while you can define macros with such
+characters. It was a sort of coincidence that this specific range of characters
+had not yet gotten the proper catcodes, but that is something users don't need to
+worry about. If your script doesn't work, we just need to initialize a few more
+characters.
+
+\startbuffer
+\def\例題#1{\example{例題 2: 数 #1}\par}
+
+\例題{2.1}
+\stopbuffer
+
+\ShowExample{3}
+
+Of course this command is now also present at the \LUA\ end:
+
+\startbuffer
+\startluacode
+    context.startexample()
+    context.例題(2.2)
+    context.stopexample()
+\stopluacode
+\stopbuffer
+
+\ShowExample{4}
+
+The \type {MKVI} parser has also been adapted to this phenomena as have the
+alternative ways of defining macros. We could already do this:
+
+\startbuffer
+\starttexdefinition test #1
+    \startexample
+        例題 3: 数 #1 \par
+    \stopexample
+\stoptexdefinition
+
+\test{3}
+\stopbuffer
+
+\ShowExample{5}
+
+But now we can also do this:
+
+\startbuffer
+\starttexdefinition 例題 #1
+    \startexample
+        例題 4: 数 #1 \par
+    \stopexample
+\stoptexdefinition
+
+\例題{4}
+\stopbuffer
+
+\ShowExample{6}
+
+Named parameters support a wider range of characters too:
+
+\startbuffer
+\def\例題#数{\example{例題 5: 数 #数}\par}
+
+\例題{5}
+\stopbuffer
+
+\ShowExample{7}
+
+So, in the end we can have definitions like this:
+
+\startbuffer
+\starttexdefinition 例題 #数
+    \startexample
+        例題 6: 数 #数 \par
+    \stopexample
+\stoptexdefinition
+
+\例題{6}
+\stopbuffer
+
+\ShowExample{8}
+
+Of course the optional (first) arguments still are supported but these stay
+Latin.
+
+\startbuffer
+\starttexdefinition unexpanded 例題 #数
+    \startexample
+        例題 7: 数 #数 \par
+    \stopexample
+\stoptexdefinition
+
+\例題{7}
+\stopbuffer
+
+\ShowExample{9}
+
+Finally Luigi wondered of we could use math symbols too and of course there is no
+reason why not:
+
+\startbuffer
+\startluacode
+    function commands.∑(...)
+        local t = { ... }
+        local s = 0
+        for i=1,#t do
+            s = s + t[i]
+        end
+        context("% + t = %s",t,s)
+    end
+\stopluacode
+
+\ctxcommand{∑(1,3,5,7,9)}
+\stopbuffer
+
+\ShowExample{10}
+
+The \CONTEXT\ source code will of course stay \ASCII, although some of the multi
+lingual user interfaces already use characters other than that, for instance
+accented characters or completely different scripts (like Persian). We just went
+a step further and supported it at the \LUA\ end which in turn introduced those
+characters into \MKVI.

+\startsection[title=Introduction]
+
+In the crited project \footnote {This is a project by Thomas Schmitz, Alan
+Braslau, Luigi Scarso and Hans Hagen funded by the Institut für Klassische und
+Romanische Philologie Universität Bonn.} we have to deal with large amounts of
+data. The sources are in \TEI\ \XML\ and processed directly in \CONTEXT\ \MKIV,
+and we have to filter content from different places in the \XML\ tree. Processing
+relies on \LUA\ a lot because we use \LUA\ for dealing with the \XML. We're
+talking about Latin and Greek texts so there is no demand for extensive font
+processing in \LUA\ is moderate. But as critical editions have lots of line
+specific referencing and notes there are some more complex layout elements
+involved, and again these use \LUA. There is also extensive use of bibliographies
+and it will be no surprise that \LUA\ comes to help too. \footnote {One of the
+objectives of the project is to update and enhance the bibliographic subsystem.}
+
+One secondary objective is to be able to process the complex documents at a speed
+of at least 20 pages per second on a modern 2014 workstation laptop. One way of
+achieving this is to use \LUAJITTEX\ which has a faster virtual \LUA\ machine.
+However, we ran into several issues with the \LUAJIT\ interpreter, which is fully
+\LUA\ language 5.1 and partly 5.2 compatible but definitely has a different low
+level implementation. In the next sections I will discuss two issues that Luigi
+and I ran into and for which we could come up with reasonable workarounds.
+
+\stopsection
+
+\startsection[title=The stacks]
+
+A \TEX\ job is normally a multi|-|pass experience. One run can produce information
+that is used in a successive one. The reason is that something can happen on page
+15 that influences the typesetting of page~9. There can even be a partial chain
+reaction: you typeset a document the first time the table of contents (and the
+pages it refers to) is not known yet but information is saved that makes it
+possible next time. That next run it gets included and it takes for instance 4
+pages. This means that all page numbers shift up. This in turn will trigger a new
+run because all cross references might change too: two digit page numbers can
+become three digits, so paragraphs can run wider, and that again can trigger more
+pages. Normally an initial three runs is enough, and with minor updates of the
+source one or two runs are enough after that.
+
+The multi|-|pass information is saved in tables in the so called utility file and
+loaded a next run. Common subtables are shared in the process. In order to
+determine if there has been crucial changes that demand an extra run, we have to
+make sure that random order in these tables is eliminated. Normally we already
+sort keys in tables when writing them to file but some tables come out in the
+order the traversing \type {next} function delivers them. In the more recent 5.2
+versions \LUA\ has added some randomness to the order in which hashed tables are
+organized, so while in previous versions we could assume that for a specific
+binary the order was the same each time, we cannot rely on that any longer. This is
+not that important for normal cases, but we compare previous and current versions
+of the utility file and pack shared tables in them as well, which means that we
+are sensitive for a change in order. But, this could be dealt with at the cost of
+some extra sorting. \footnote {In \CONTEXT\ we also pack font tables which saves
+lots of memory and also some load time).}
+
+Anyway, this kind of changes in the \LUA\ machinery is harmless apart from taking
+some time to adapt to it. It is also the reason why we cannot simply push a new
+update of \LUA\ into \LUATEX\ because low level changes can have an (yet unknown)
+impact. Of course performance is the biggest issue here: we don't want a slower
+\LUATEX.
+
+In the past we already reported on the benefits of \LUAJITTEX, especially its
+faster virtual machine. We don't benefit from jitting; on the contrary it slows
+us down. One reason is that we cross the \LUA||\CCODE\ boundary often and hardly
+use any of the optimized functions. Part of the speed is achieved by a different
+implementation deep down and one of them is a different virtual machine
+instruction set. While \LUA\ can go real big in terms of memory and table
+construction, \LUAJIT\ limits us to at most 2G memory and poses some 64K
+limitations in functions and table constructors. The memory is not so much the
+issue in the crited project but the (nested) table constructor is. When we have a
+few tens of thousands of cross references, index entries and|/|or list entries we
+simply cannot load the multi|-|pass data. A few days of playing with splitting up
+nested tables didn't help much: it made the code look horrible and eventually we
+again ran into a maximum of 64K someplace as a \type {dofile} effectively makes a
+function that gets run and \LUAJIT\ doesn't like that size. For the record: we
+don't have such issues with large font tables probably because they are just one
+big table. The reason why we cannot use that approach is that serializing the
+potentially very large tables in the utility file also has limitations.
+
+Eventually this could be solved by assuming only forward referencing for certain
+registers. That way we only used the index entries collected in memory during the
+run and as long as we don't put a register before it's entries are defined we're
+okay. So here we have a typical case where one can set an option to circumvent
+an engine limitation. \footnote {A decade ago similar tricks had to be used to
+support hundreds of thousands of hyperlinks in \TEX\ engines with at that time
+limited memory capabilities.} Explaining this in a user manual is a challenge,
+because an error message like the following is not that helpful:
+
+\starttyping
+main function has more than 65536 constants
+\stoptyping
+
+But, once we could generate these indices again by posing some limitations,
+\LUAJITTEX\ had other issues. This time we got excessive runtime and we spent
+quite some time sorting that one out. More on that in the next section.
+
+\stopsection
+
+\startsection[title=Hashing]
+
+One of the reasons why (text processing with) \LUA\ is rather fast is that it
+hashes its strings so that a test for equality is real fast. This means that for
+each string that enters \LUA\ a hash value is calculated and that hash is used in
+comparisons. Of course hashing takes time, but especially when you work with lots
+of tables the advantage of a simple hash compare outweighs this one||time
+hashing. On the other hand, if you work with files and process lines, and maybe
+split these in words, you might end up with a lot of unneeded hashing. But, in
+\LUATEX\ and therefore \MKIV\ we benefit from hashing a lot. In \LUA\ 5.2 the
+hash function was adapted so that only strings upto than (default) 40 characters
+get hashed. In practice we're not affected much by this, as most keywords we use
+are shorter than this boundary. And in \CONTEXT\ we do quite some keyword checking.
+
+So, when we were conducting tests with these large registers, we were surprised
+that \LUAJITTEX\ performed significantly slower (ten times or more) that stock
+\LUATEX, while until then we had observed that a \LUAJITTEX\ run was normally
+some 20 to 40\% faster.
+
+The first impression was that it related to the large amount of strings that are
+written from \LUA\ to \TEX. After index entries are collected, they are sorted
+and the index is flushed to \TEX. This happens in one go, and \TEX\ code ends up
+in the \TEX\ input stack. Some actions are delayed and create callbacks to \LUA,
+so some wrapping in functions happens too. That means that some (\LUA) strings
+are only freed later on, but that proved not to be the main problem.
+
+When the entries are typeset, an interactive cross reference is kept track of and
+these exist till the document is closed and the referencing information is
+written to the \PDF\ file. Of course we could tweak this but once you start along
+that path there is no end to writing ugly hacks.
+
+Eventually we found that the slowdown relates to hashing, especially because that is
+not the first area where you look. Why is this? The specific register concerned lots
+of small greek words, pointing to locations in a text, where locations looked like
+\type {1.2.3}. In case you wonder why greek is mentioned: in multi|-|byte \UTF\
+sequences there is a lot of repetition:
+
+\startluacode
+local byte = string.byte
+function sample(s)
+    context.NC() context(s)
+    context.NC() context.ttx(false)
+    for b in string.utfvalues(s) do
+        context("%02X ",b)
+    end
+    context.NC() context.ttx(false)
+    for b in string.gmatch(s,".") do
+        context("%02X ",byte(b))
+    end
+    context.NC() context.NR()
+end
+
+context.starttabulate { "||||" }
+context.FL()
+context.NC() context.bold("word")
+context.NC() context.bold("unicode")
+context.NC() context.bold("bytes")
+context.NC() context.NR()
+context.FL()
+sample("βίον")
+sample("βίου")
+sample("βιοὺς")
+sample("βουλὴν")
+sample("βουλῆς")
+context.LL()
+context.stoptabulate()
+\stopluacode
+
+When cross referencing these index entries with their origin, you end up with
+reference identifiers like \type {foo:1.2.3} or, because \CONTEXT\ has automated
+internal references (which are rather efficient in the resulting \PDF), we get
+\type {aut:1}, \type {aut:2} upto in this case some 30.000 of them.
+
+The problem with hashing is as follows. When we write commands to \TEX\ or use
+data with a repetitive property, the similarity of these strings can be hard on
+the hasher as it can produce similar hash keys in which case collisions need to
+be dealt with. I'm no expert on hashing but looking at the code shows that in
+\LUAJIT\ (at least in the version we're talking about) the string is seen as
+chunks of 4 bytes. The first, last, middle and halfway middle chunks are
+consulted and after some bit juggling we get a hash value. In the case of strings
+like the following it is clear that the beginning and end look quite the same:
+
+\starttyping
+foo:000001  foo:010001  foo:100001
+\stoptyping
+
+or:
+
+\starttyping
+foo:1.2.12  foo:1.3.12  foo:1.4.12  foo:1.5.12
+\stoptyping
+
+It seems that the used method of hashing is somewhat arbitrary and maybe tuned
+for specific applications. In order to see what the impact is of hashing quite
+similar strings, some experiments were conducted: with \LUATEX\ 0.73 using \LUA\
+5.2 hashing, with \LUAJITTEX\ 0.73, and with the same \LUAJITTEX\ but using the
+hash variant of native \LUA\ 5.1. For each variant we ran tests where strings of
+increasing length were combined with a number (running from one to one million).
+
+\starttabulate[|||]
+\NC none   \NC <string>                   \NC \NR
+\NC right  \NC <string> <number>          \NC \NR
+\NC left   \NC <number> <string>          \NC \NR
+\NC center \NC <string> <number> <string> \NC \NR
+\NC edges  \NC <number> <string> <number> \NC \NR
+\stoptabulate
+
+The differences between engines can be seen in tables in the next page. In the
+fourth table we summarize which engine performs best. Keep in mind that
+\LUAJITTEX\ has the advantage of the faster virtual machine so it has an
+additional speed advantage.
+
+We show three tables with measurements. The \type {none} column shows the
+baseline of the test:
+
+\starttyping
+
+local t = { }
+for i=1,1000000 do
+    t[i] = i
+end
+\stoptyping
+
+The column tagged \quote {right} does this:
+
+\starttyping
+local t = { }
+for i=1,1000000 do
+    t[i] = text .. i
+end
+\stoptyping
+
+And \quote {left} does:
+
+\starttyping
+local t = { }
+for i=1,1000000 do
+    t[i] = i .. text
+end
+\stoptyping
+
+That leaves \quote {center}:
+
+\starttyping
+local t = { }
+for i=1,1000000 do
+    t[i] = text .. i .. text
+end
+\stoptyping
+
+and \quote {edges}:
+
+\starttyping
+local t = { }
+for i=1,1000000 do
+    t[i] = i .. text .. i
+end
+\stoptyping
+
+Of course there is also the loop and the concatenation involved so the last two
+variants have some more overhead. We show some measurements in \in {tables}
+[tab:torture-1], \in [tab:torture-2] \in {and} [tab:torture-3]. So, there we have
+strings like:
+
+\starttyping
+2abc
+222abc
+22222abc
+abc222222
+222222abc222222
+222222abc222222
+abc2222abc
+\stoptyping
+
+and so on. Of course a million such strings makes not much sense in practice but
+it serves our purpose of testing.
+

+    \scale
+      [height=\the\dimexpr\textheight-3\lineheight\relax]

+      {\vbox{\ctxlua{moduledata.luatests.showhashing { filename = "luatest-hash-luajittex-073-LUA51.lua" }}}}
+\stopplacetable
+
+In these tables you can see some extremes. On the average \LUA\ 5.2 performs
+quite okay as does standard \LUAJIT. However, when we bring the 5.1 hash variant
+into \LUAJITTEX\ we get a more predictable average performance as it deals better
+with some of the extreme cases that make \LUAJITTEX\ crawl compared to \LUATEX.
+We have done more tests and interesting is to see that in the 5.1 (and derived
+5,2) method there are sometimes cases where odd lengths perform much worse than
+even lengths. Red values are larger than two times the average, blue values
+larger than average while green values indicate a less than half average value.
+
+In \in {table} [tab:compare-1] we show which method performs best relative to each

+The 5.1 hasher runs over the string with a step that depends on the length of the
+string. We've seen that in 5.2 it doesn't hash strings larger than 40 characters.
+The step is calculated by shifting the length (by default) over 5 bits. This
+means that for strings of size 32 and more the step becomes 2 which is why we see
+this odd|/|even timing issue in the tables. Basically we hash at most 32
+characters of the 40. The next table shows that the less characters we take
+into account (first column) the less unique keys we get (second column).

+
+Of course, in practice, in \LUA\ 5.2 the longer string exceeds 40 characters so
+is never hashed anyway. Apart from this maximum, the \LUA\ hash code looks like this:
+
+\starttyping
+/* Lua will use at most ~(2^LUAI_HASHLIMIT) bytes from
+a string to compute its hash */
+...
+h = cast(unsigned int,len) ;
+step = (len>>LUAI_HASHLIMIT) + 1 ;
+for (l1=len; l1>=step; l1-=step) {
+   h = h ^ ((h<<5) + (h>>2) + cast(unsigned char,str[l1-1])) ;
+}
+...
+\stoptyping
+
+This translates in verbose \LUA\ function as follows:
+
+\starttyping
+function string.luahash(str,shift)
+    local len  = #str
+    local hash = len
+    local step = bit32.rshift(len,shift or 5) + 1
+    for i=len,1,-step do
+        hash = bit32.bxor(hash, (
+            bit32.lshift(hash,5) +
+            bit32.rshift(hash,2) +
+            string.byte(string.sub(str,i,i))
+        ) )
+    end
+    return hash
+end
+\stoptyping
+
+The reader can argue that the following string would perform better:
+
+\starttyping
+/Subtype/Link/Border[0 0 0]/F 4/A 12 0 R
+\stoptyping
+
+but this is not the case. Also, here we use \PDF\ code, but similar cases can
+happen if we flush \TEX\ commands:
+
+\starttyping
+\dothisorthat{1}
+\dothisorthat{101}
+\dothisorthat{10101}
+\stoptyping
+
+And in the case of \UTF\ strings, it remains a fact that when characters need two
+bytes a sequence can end up with each odd or even byte being the same. This is
+one more reason to support upto 64 byte (or 40 in practice) hashing.
+
+Because of this we decided to experiment with a value of 64 instead. \footnote {Of
+course, in \LUATEX, the length limit kicks in before we get to 64.} We can do the
+same when we use the \LUA\ 5.1 method in \LUAJIT. In \in {table} [tab:torture-4]
+\in {and} [tab:torture-5] we show the timings. Interesting is that we lost the
+extremes now. The performance of the default settings are compared with the higher
+values in \in {table} [tab:compare-2]. Of course the numbers are just indications
+and there might be small differences between test runs. Therefore we use a threshold
+of 5\% when we compare two methods.

+So how does this affect us in document production? It is not that hard to get a
+processing rate of a few dozen pages per second on a modern machine, even with
+somewhat complex documents, where \XML\ turns into \PDF. However, interactivity
+comes somehow with a price when we use \LUAJITTEX. In \CONTEXT\ \MKIV\ we do all
+\PDF\ annotations in \LUA\ and that involves assembling dictionaries. Here are
+two examples, a destination:
+
+\starttyping
+<< /D [ 15 0 R /Fit ] /S /GoTo >>
+\stoptyping
+
+and a reference:
+
+\starttyping
+/Subtype /Link /Border [ 0 0 0 ] /F 4 /A 16 0 R
+\stoptyping
+
+These strings are build with small variations and at some point end up in the \PDF\
+file. The same string can end up in the file several times, although sometimes we
+can create a reusable object. In the last case we keep them at the \LUA\ end as
+reference to such a shareable object, a key in an object reference hash.  Now imagine
+that we have some 30K of such references and/or destinations, which indeed happens in
+crited documents. In the next two lines we use a \type {*} to show where the
+differences are:
+
+\starttyping
+<< /D [ * 0 R /Fit ] /S /GoTo >>
+/Subtype /Link /Border [ 0 0 0 ] /F 4 /A * 0 R
+\stoptyping
+
+If we replace these \type {*} by a number, there are big differences between the
+engines with respect to the time needed. This is summarized in the next table.
+\footnote {The numbers concern 30K hash creations. The time shown is the average
+over 30 runs.}

+
+Especially the second case behaves bad in \LUAJIT. Say that a result comes out
+as:
+

+/Subtype /Link /Border [ 0 0 0 ] /F 4 /A 123 0 R

+\stoptyping
+
+The \LUAJIT\ hasher (more or less) looks at the first~4, last~4, middle~4 and
+somewhere a quarter along the string, and uses these sequences for the
+calculation, so you can imagine that there are clashes. The \LUA\ 5.1 hasher runs
+over part of the string and sees more of the difference. The 5.2 hasher has a
+threshold and doesn't hash at all when the length exceeds (by default) 40
+characters, which is the case with the second string. Looking at only specific
+parts of a string is somewhat arbitrary and what works for one kind of
+application is not always good for another.
+
+After these tests we decided that it makes sense to replace the \LUAJIT\ hash
+calculation by the traditional \LUA\  one (or at least give users a choice at
+startup. The choice of hash is a runtime option:
+
+\starttyping
+mtxrunjit --script context --jithash=lua51    ......
+mtxrunjit --script context --jithash=luajit20 ......
+\stoptyping
+
+For the moment we default to the traditional \LUA\ 5.1 hashing method. Although
+it can behave real bad on some large strings we think that chances are low that
+this will happen in practice. An overall good performance on strings like the
+hyperlink examples is more important. Using the \LUA\ 5.2 method would be even
+better but it required a change in the virtual machine and that is not something
+we have in mind.

+% In \LUA\ strings are hashed which makes a test for equality fast and in \LUATEX\

+\startchapter[title={Font expansion}]
+
+\startsection[title=Introduction]
+
+A lot in \LUATEX\ is not new. It started as a mix of \PDFTEX\ (which itself is
+built on top of original \TEX\ and \ETEX) and the directional bits of \ALEPH\
+(which is a variant of \OMEGA). Of course large portions have been changed in the
+meantime, most noticeably the input encoding (\UNICODE), fonts with a more
+generic fontloader and \LUA\ based processing, \UNICODE\ math and related font
+rendering, and many subsystems can be overloaded or extended. But at the time I
+write this (end of January 2013) the parbuilder still has the \PDFTEX\ font
+expansion code.
+
+This code is the result of a research project by \THANH. By selectively widening
+shapes a better greyness of the paragraph can be achieved. This trick is inspired
+by the work of Hermann Zapf and therefore, instead of expansion, we often talk of
+{\em hz} optimization.
+
+It started with (runtime) generated \METAFONT\ bitmap fonts and as a consequence
+we ended up with many more font instances. However, when eventually bitmap
+support was dropped and outlines became the norm, the implementation didn't
+change much. Also some of the real work was delegated to the backend and as it
+goes then: never change a working system if there's no reason.
+
+When I played with the \LUA\ based par builder I quickly realized that this
+implementation was far from efficient. It was already known that enabling it
+slowed down par building and I saw that this was largely due to many redundant
+calculations, generating auxiliary fonts, and the interaction between front- and
+backend. And, as I seldom hesitate to reimplement something that can be done
+better (one reason why \CONTEXT\ is never finished) I came to an alternative
+implementation. That was 2010. What helped was that by that time Hartmut Henkel
+already had made the backend part cleaner, in the sense that instead of including
+multiple instances of the same font (but with different glyph widths) the base
+font was transformed in|-|line. This made me realize that we could use just one
+font in the frontend and pass the scale with the glyph node to the backend. And
+so, an extra field was added to glyphs nodes in order to make experiments
+possible.
+
+More than two years later (January 2013) I finally took up this pet project and
+figured out how to adapt the backend. Interestingly a few lines of extra code
+we all that was needed. At the same time the frontend part became much simpler,
+that is, in the \LUA\ parbuilder. But eventually it will be retrofitted into the
+core engine, if only because that's much faster.
+
+\stopsection
+
+\startsection[title=The changes]
+
+The most important changes are the following. Instead of multiple font instances,
+only one is used. This way less memory is used, no extra font instances need to
+be created (and those \OPENTYPE\ fonts can be large).
+
+Because less calculations are needed the code looks less complex and more elegant.
+Okay, the parbuilder code will never really look easy, if only because much more
+is involved.
+
+The glyph related factors are related to the emwidth. This makes not much sense
+so in \CONTEXT\ we define them in fractions of the character width, map them onto
+emwidths, and in the parbuilder need to go to glyph related widths again. If we can
+get rid of these emwidths, we have less complex code.
+
+Probably for reasons of efficiency an expanded font carries a definition that
+tells how much stretch and shrink is permitted and how large the steps are. So,
+for instance a font can be widened 5\% and narrowed 3\% in steps of 1\% which
+gives at most 8 extra instances. There is no real reason why this should be a
+font property and the parbuilder cannot deal with fonts with different steps
+anyway, so it makes more sense to make it a property of the paragraph and treat
+all fonts alike. In the \LUA\ based variant we can even have more granularity but
+we leave that for now. In any case this will lift the limitation of mixed font
+usage that is present in the original mechanism.
+
+The front- and backend code with repect to expansion gets clearly separated. In
+fact, the backend doesn't need to do any calculations other than applying the
+factor that is carried with the glyph. This and previously mentioned simplifications
+make the mechanism more efficient.
+
+It is debatable if expansion needs to be applied to font kerns, as is the case in
+the old mechanism. So, at least it should be an option. Removing this feature
+would again made the code nicer. If we keep it, we should keep in mind that
+expansion doesn't work well with complex fonts (say Arabic) but I will look into
+this later. It might be feasible when using the \LUA\ based variant because then
+we can use some of the information that is carried around with the related
+mechanisms. Of course this then related to the \LUA\ based font builder.

+\startchapter[title={Introduction}]
+
+During the development of \LUATEX\ we wrapped up the state of affairs in articles
+and reports. Upto version 0.50 we tagged them as \quote {\MKIV} (the transition
+from \MKII), while for the next 0.25 versions we bundled them in \quote {hybrid}
+(the rewrite of \CONTEXT). The next series goes under the name \type {about} as
+one might wonder what all this \LUATEX\ and \CONTEXT\ is about. After all we've
+now reached a state where we can think about future applications instead of
+improving older features as that process is ongoing.
+
+As we're a bit beyond experimenting now, the focus will be on practical usage and
+of course we target on applications that the \LUA\ and \TEX\ combination makes
+possible, either new or in a renewed form. Some of the chapters will eventually

+\startsection[title=Introduction]
+
+If you have a bit of a background in programming and watch kids playing video
+games, either or not on a dedicates desktop machine, a console or even a mobile
+device, there is a good change that you realize how much processing power is
+involved. All those pixels get calculated many times per second, based on a
+dynamic model that not only involves characters, environment, physics and a story
+line but also immediately reacts on user input.
+
+If on the other hand in your text editor hit the magic key combination that
+renders a document source into for instance a \PDF\ file, you might wonder why
+that takes so many seconds. Of course it does matter that some resources are
+loaded, that maybe images are included, and lots of fuzzy logic makes things
+happen, but the most important factor is without doubt that \TEX\ macros are not
+compiled into machine code but into an intermediate representation. Those macros
+then get expanded, often over and over again, and that a relative slow process.
+As (local) macros can be redefined any time, the engine needs to take that into
+account and there is not much caching going on, unless you explicitly define
+macros that do so. Take this:
+
+\starttyping
+\def\bar{test}
+\def\foo{test \bar\space test}
+\stoptyping
+
+Even if the definition of \type {\test} stays the same, that if \type {\bar} can
+change:
+
+\starttyping
+\foo \def\bar{foo} \foo
+\stoptyping
+
+There is no mechanism to freeze the meaning of \type {\bar} in \type {\foo},
+something that is possible in the other language used in \CONTEXT:
+
+\starttyping
+local function bar() context("test") end
+function foo() context("test ") bar() context(" test") end
+\stoptyping
+
+Here we can use local functions to limit their scope.
+
+\starttyping
+foo() local function bar() context("foo") end foo()
+\stoptyping
+
+In a way you can say that \TEX\ is a bit more dynamic that \LUA, and optimizing
+(as well as hardening) it is much more difficult. In \CONTEXT\ we already
+stretched that to the limits, although occasionally I find ways to speed up a
+bit. Given that we spend a considerable amount of runtime in \LUA\ it makes sense
+to see what we can gain there. We have less possible interference and often a more
+predictable outcome as \type {bar}s won't suddenly become \type {foo}s.
+
+Nevertheless, the dynamic nature of both \TEX\ and \LUA\ has some impact on
+performance, especially when they do most of the work. While in games there are
+dedicated chips to do tasks, for \TEX\ there aren't. So, we're sort of stuck when
+it comes to speeding up the process to the level that is similar to advanced
+games. In the next sections I will discuss a few aspects of possible speedups and
+the reason why it doesn't work out as expected.
+
+\stopsection
+
+\startsection[title=Jitting]
+
+Let's go back once more to Luigi's nightmare of disappointing jit \footnote
+{Luigi Scarso is the author of \LUAJITTEX\ and we have reported on experiments
+with this variant of \LUATEX\ on several occasions.} We already know that the
+virtual machine of \LUAJIT\ is about twice as fast as the standard machine. We
+also experienced that enabling jit can degrade performance. Although we did
+observe some real drastic drop in performance when testing functions like \type
+{math.random} using the \type {mingw} compiler, we also saw a performance boost
+with simple pure \LUA\ functions. In that respect \LUAJIT\ is an impressive
+effort. So, it makes sense to use \LUAJITTEX\ even if in theory it could be
+faster.
+
+Next some tests will be shown. The timings are snapshots so different versions of
+\LUAJITTEX\ can have different outcomes. The tests are mostly used for
+discussions between Luigi and me and further experiments and believe me: we've
+really done all kind of tests to see if we can get some speed out of jitting.
+After all it's hard to believe that we can't gain something from it, so we might
+as do something wrong.
+
+Each test is run \NOfLuaJitRuns\ times. These are of course non|-|typical
+examples but they illustrate the principle. Each time we show two measurements:
+one with jit turned on, and one with jit off, but in both cases the faster
+virtual machine is enabled. The times shown are of course dependent on the
+architecture and operating system, but as we are only interested in relative
+times it's enough to know that we run 32 bit mingw binaries under 64 bit Windows
+8 on a modern quad core Ivy bridge \CPU. We did most tests with \LUAJIT\ 2.0.1
+but as far as we can see 2.0.2 has a similar performance.

+
+What we do observe here is that turning on jit doesn't always help. By design the
+current just|-|in|-|time compiler aborts optimization when it sees a function
+that is not known. This means that in \LUAJITTEX\ most code will not get jit,
+because we use built|-|in library calls a lot. Also, in version 2.0 we notice
+that a bit of extra wrapping will make performance worse too. This might be why
+for us jitting doesn't work out the way it is advertised. Often performance tests
+are done with simple functions that use built in functions that do get jit. And
+the more of those are supported, the better it gets. Although, when you profile a
+\CONTEXT\ run, you will notice that we don't call that many standard library
+functions, at least not so often that jitting would get noticed.
+
+A safe conclusion is that you can benefit a lot from the fast virtual machine but
+should check carefully if jit is not having a negative impact. As it is turned on
+by default in \LUAJIT\ (but off in \LUAJITTEX) it might as well get unnoticed,
+especially because there is always a performance gain due to the faster virtual
+machine and that might show more overall gain than the drawback of jitting
+unjittable code. It might just be a bit less drastic then possible because of
+artifacts mentioned here, but who knows what future versions of \LUAJIT\ will
+bring.
+
+Maybe sometime we can benefit from \type {ffi} but it makes no sense to mess up
+the \CONTEXT\ code with related calls: it looks ugly and also makes the code
+unusable in stock \LUA, so it is a a sort of no|-|go. There are some suggestions
+in \LUAJIT\ related posts about adapting the code to suit the jitter, but again,
+that makes no sense. If we need to keep a specific interpreter in mind, we could
+as well start writing everything in C. So, our hopes are on future versions of
+stock \LUA\ and \LUAJIT. Luigi uncovered the following comment in the source code:
+
+\starttyping
+/* C functions can have arbitrary side-effects and are not
+recorded (yet). */
+\stoptyping
+
+Although the \type {(yet)} indicates that at some point this restriction can be
+lifted, we don't expect this to happen soon. And patching the jit machinery
+ourselves to suite \LUATEX\ is no option.
+
+There is an important difference between a \LUATEX\ run and other programs: they
+are runs and these live short. A lot of code gets executed only once of a few
+times (like loading fonts), or gets executed in such different ways that (branch)
+prediction is hard. If you run a web server using \LUA\ it runs for weeks in a
+row so optimizing a function pays off, given that it gets optimized. When you
+have a \LUA\ enhanced interactive program, again, the session is long enough to
+benefit from jitting (if applied). And, when you crunch numbers, it might pay off
+too. In practice, a \TEX\ run has no such characteristics.
+
+\stopsection
+
+\startsection[title=Implementation]
+
+In \LUA\ 5.2 there are some changes in the implementation compared to 5.1 and
+before. It is hard to measure the impact of that but it's probably a win some
+here and loose some there situation. A good example is the way \LUA\ deals with
+strings. Before 5.2 all strings were hashed, but now only short strings are
+(at most 32 bytes are looked at). Now, consider this:
+
+\startitemize
+    \startitem
+        In \CONTEXT\ we do all font handling in \LUA\ and that involves lots of
+        tables with lots of (nicely hashed) short keys. So, comparing them is
+        pretty fast.
+    \stopitem
+    \startitem
+        We also read a lot from files, and each line passes filters and such
+        before it gets passed to \TEX. There hashing is not really needed,
+        although when it gets processed by filters it might as well save some
+        time.
+    \stopitem
+    \startitem
+        When we go from \TEX\ to \LUA\ and reverse, lots of strings are involved
+        and many of them are unique and used once. There hashing might bring a
+        penalty.
+    \stopitem
+    \startitem
+        When we loop over a string with \type {gmatch} or some \type {lpeg}
+        subprogram lots of (small) strings can get created and each gets hashed,
+        even if they have a short livespan.
+    \stopitem
+\stopitemize
+
+The above items indicate that we can benefit from hashing but that sometimes it
+might have a performance hit. My impression is that on the average we're better
+off by hashing and it's one of the reasons why \LUA\ is so fast (and useable).
+
+In \TEX\ all numbers are integers and in \LUA\ all numbers are floats. On modern
+computers dealing with floating point is fast and we're not crunching numbers
+anyway. We definitely would have an issue when numbers were just integers and an
+upcoming mixed integer|/|float model might not be in our advantage. We'll see.
+
+I had expected to benefit from bitwise operations but so far never could find a
+real application in \CONTEXT, at least not one that had a positive impact. But
+maybe it's just a way of thinking that hasn't evolved yet. Also, the fact that
+functions are used instead of a real language extension makes it less possible
+that there is a speedup involved.
+
+\stopsection
+
+\startsection[title=Garbage collection]
+
+In the beginning I played with tuning the \LUA\ garbage collector in order to
+improve performance. For some documents changing the step and multiplier worked
+out well, but for others it didn't, so I decided that one can best leave the
+values as they are. Turning the garbage collector off as expected gives a
+relative small speedup, and for the average run the extra memory used can be
+neglected. Just keep in mind that a \TEX\ run are never persistent so memory
+can't keep filling. I did some tests with the in theory faster (experimental)
+generational mode of the garbage collector but it made runs significantly slower.
+For instance processing the \type {fonts-mkiv.pdf} went from 9 to 9.5 seconds.
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+So what is, given unpredictable performance hits of advertised optimizations, the
+best approach. It all starts by the \LUA\ (and \TEX) code: sloppy coding can have
+a price. Some of that can be disguised by clever interpreters but some can't. If
+the code is already fast, there is not much to gain. When going from \MKII\ to
+\MKIV\ more and more \LUA\ got introduced and lots of approaches were
+benchmarked, so, I'm already rather confident that there is not that much to
+gain. It will never have the impressive performance of interactive games and
+that's something we have to live with. As long as \LUA\ stays lean and mean,
+things can only get better over time.

+\startsection[title=Introduction]
+
+As part of the crited project Luigi and I also tried to identity weak spots in
+the engine and although we found some issues not all were dealt with because
+complicating the machinery makes no sense. However just like the new \type
+{properties} mechanism provides a real simple way to associate extra \LUA\ data
+to a node without bothering about freeing it when a node is flushed, the next
+\type {luafunctions} mechanism provides an additional and fast way to cross the
+\TEX||\LUA\ boundary.
+
+\stopsection
+
+\startsection[title=Callbacks]
+
+In \LUATEX\ we can create more functionality by using \LUA\ which means that we
+end up (at least in \CONTEXT) with a constant switching between \TEX\ macro
+expansion and \LUA\ code interpretation. The magic word in this process is \type
+{callback} and there are two variants:
+
+\startitemize
+
+\startitem At well defined moments in processing its input and node lists, \TEX\
+will check if a specific callback is defined and if so, it will run that code.
+\stopitem
+
+\startitem As part of the input you can have a \type {\directlua} command and
+that one gets expanded and processed. It can print back content into the current
+input buffer. \footnote {Currently this process is somewhat more complex than
+needed, which is a side effect of supporting multiple \LUA\ states in the first
+versions of \LUATEX. We will clean up this mechanism at some point.} \stopitem
+
+\stopitemize
+
+The first type is call a \quote {direct} callback because \TEX\ calls it
+directly, and the second one is an \quote {indirect} one (even if the command is
+\type {\directlua}). It has a deferred cousin \type {\latelua} that results in a
+node being inserted that will become a \LUA\ call during shipout, when the page
+is turned into a \PDF\ stream.
+
+A callback of the first category is pretty fast because the code is already
+translated in \LUA\ bytecode. Checking if a callback has been assigned at all is
+fast too. The second variant is slower because each time the input has to be
+interpreted and checked on validity. Then there is of course some overhead in
+making the call itself.
+
+There is a subtle aspect there. If you have a document that needs say ten calls
+like:
+
+\starttyping
+\directlua{tex.print("[x]")}
+\stoptyping
+
+and you have these calls inlined, you end up with ten times conversion into
+tokens (\TEX's internal view) and ten times conversion back to a string that gets
+fed into \LUA. On the other hand,
+
+\starttyping
+\def\MyCall{\directlua{tex.print("[x]")}}
+\stoptyping
+
+where we call \type {\MyCall} ten times is more efficient because we have already
+tokenized the \type {\directlua}. If we have
+
+\starttyping
+foo foo foo \directlua{tex.print("[1]")} ...
+bar bar bar \directlua{tex.print("[2]")} ...
+\stoptyping
+
+It makes sense to wrap this into a definition:
+
+\starttyping
+\def\MyCall#1{\directlua{tex.print("[#1]")}}
+\stoptyping
+
+and use:
+
+\starttyping
+foo foo foo \MyCall{1} bar bar bar \MyCall{1} ...
+\stoptyping
+
+Of course this is not unique for \type {\directlua} and to be honest, apart from
+convenience (read: less input) the gain often can be neglected. Because a macro
+package wraps functionality in (indeed) macros we already save us the tokenization
+step. We can save some time by wrapping more in a function at the \LUA\ end:
+
+\starttyping
+\startluacode
+function MyFloat(f)
+    tex.print(string.format("%0.5f",f))
+end
+\stopluacode
+
+\def\MyFloat#1%
+  {\directlua{MyFloat(#1)}}
+\stoptyping
+
+This is somewhat more efficient than:
+
+\starttyping
+\def\MyFloat#1%
+  {\directlua{tex.print(string.format("\letterpercent0.5f",#1))}}
+\stoptyping
+
+\stopsection
+
+Of course this is only true when we call this macro a lot of times.
+
+\startsection[title=Shortcuts]
+
+When we talk of \quote {often} or \quote {a lot} we mean many thousands of calls.
+There are some places in \CONTEXT\ where this is indeed the case, for instance
+when we process large registers in critical editions: a few hundred pages of
+references generated in \LUA\ is no exception there. Think of the following:
+
+\starttyping
+\startluacode
+function GetTitle(n)
+    tex.print(Entries[n].title)
+end
+\stopluacode
+
+\def\GetTitle#1%
+  {\directlua{GetTitle(#1)}}
+\stoptyping
+
+If we call \type {\GetTitle} ourselves it's the same as the \type {\MyFloat}
+example, but how about this:
+
+\starttyping
+\def\GetTitle#1%
+  {{\bf \directlua{GetTitle(#1)}}}
+
+\startluacode
+function GetTitle(n)
+    tex.print(Entries[n].title)
+end
+
+function GetEntry(n)
+    if Entries[n] then
+        tex.print("\\directlua{GetTitle(",n,")}")
+        -- some more action
+    end
+end
+\stopluacode
+\stoptyping
+
+Here we have two calls where one is delayed till a later time. This delay results
+in a tokenization and transation to \LUA\ so it will cost time. A way out is this:
+
+\starttyping
+\def\GetTitle#1%
+  {{\bf \luafunction#1}}
+
+\startluacode
+local functions = tex.get_functions_table()
+
+function GetTitle(n)
+    tex.print(Entries[n].title)
+end
+
+function GetEntry(n)
+    if Entries[n] then
+        local m = #functions+1
+        functions[m] = function() GetTitle(n) end
+        tex.print("\\GetTitle{",m,"}")
+        -- some more action
+    end
+end
+\stopluacode
+\stoptyping
+
+We define a function at the \LUA\ end and just print a macro call. That call itself
+calls the defined function using \type {\luafunction}. For a large number
+of calls this is more efficient but it will be clear that you need to make sure that
+used functions are cleaned up. A simple way is to start again at slot one after (say)
+100.000 functions, another method is to reset used functions and keep counting.
+
+\starttyping
+\startluacode
+local functions = tex.get_functions_table()
+
+function GetTitle(n)
+    tex.print(Entries[n].title)
+end
+
+function GetEntry(n)
+    if Entries[n] then
+        local m = #functions+1
+        functions[m] = function(slot) -- the slot number is always
+            GetTitle(n)               -- passed as argument so that
+            functions[slot] = nil     -- we can reset easily
+        end
+        tex.print("\\GetTitle{",m,"}")
+        -- some more action
+    end
+end
+\stopluacode
+\stoptyping
+
+As you can expect, in \CONTEXT\ users are not expect to deal directly with
+functions at all. Already for years you can so this:
+
+\starttyping
+\def\GetTitle#1%
+  {{\bf#1}}
+
+\startluacode
+function GetEntry(n)
+    if Entries[n] then
+        context(function() context.GetTitle(Entries[n].title) end)
+        -- some more action
+    end
+end
+\stopluacode
+\stoptyping
+
+Upto \LUATEX\ 0.78 we had a \CONTEXT\ specific implementation of functions and
+from 0.79 onwards we use this new mechanism but users won't see that in practice.
+In the \type {cld-mkiv.pdf} manual you can find more about accessing \CONTEXT\
+from the \LUA\ end.
+
+Keep in mind that \type {\luafunction} is not that clever: it doesn't pick up
+arguments. That will be part of future more extensive token handling but of
+course that will then also be a real slow downer because a mix of \TEX\
+tokenization and serialization is subtoptimal (we already did extensive tests
+with that).
+
+\stopsection
+
+\startsection[title=Helpers]
+
+The above mechanism demands some orchestration in the macro package. For instance
+freeing slots should be consistent and therefore user should not mess directly
+with the functions table. If you really want to use this feature you can best do this:
+
+\starttyping
+\startctxfunction MyFunctionA
+    context(" A1 ")
+\stopctxfunction
+
+\startctxfunctiondefinition MyFunctionB
+    context(" B2 ")
+\stopctxfunctiondefinition
+
+\starttext
+    \dorecurse{10000}{\ctxfunction{MyFunctionA}}   \page
+    \dorecurse{10000}{\MyFunctionB}                \page
+    \dorecurse{10000}{\ctxlua{context(" C3 ")}}    \page
+    \dorecurse{10000}{\ctxlua{tex.sprint(" D4 ")}} \page
+\stoptext
+\stoptyping
+
+In case you're curious about performance, here are timing. Given that we have
+10.000 calls the gain is rather neglectable especially because the whole run
+takes 2.328 seconds for 52 processed pages resulting in 22.4 pages per second.
+The real gain is in more complex calls with more tokens involved and in \CONTEXT\
+we have some placed where we run into the hundreds of thousands. A similar
+situation occurs when your input comes from databases and is fetched stepwise.
+
+\starttabulate[|c|c|c|c|]
+\NC \bf A \NC \bf B \NC \bf C \NC \bf D \NC \NR
+\NC 0.053 \NC 0.044 \NC 0.081 \NC 0.081 \NC \NR
+\stoptabulate
+
+So, we can save 50\% runtime but on a simple document like this a few percent is
+not that much. Of course many such few percentages can add up, and it's one of
+the reasons why \CONTEXT\ \MKIV\ is pretty fast in spite of all the switching
+between \TEX\ and \LUA. One objective is that an average complex document should
+be processed with a rate of at least 20 pages per second and in most cases we
+succeed. This fast function accessing can of course trigger new features in
+\CONTEXT, ones we didn't consider useful because of overhead.
+
+Keep in mind that in most cases, especially when programming in \LUA\ directly
+the \type {context} command already does all kind of housekeeping for you. For
+instance it also keeps track of so called trial typesetting runs and can inject
+nodes in the current stream as well. So, be warned: there is no real need to
+complicate your code with this kind of hackery if some high level subsystem
+provides the functionality already.

+
+\startsection[title=Introduction]
+
+In the next sections I will discuss the way we deal with stacked content in
+\CONTEXT\ \MKIV\ and in particular extensible characters. The mechanism describe
+here is actually more generic and can also deal with regular text. The stacker
+code is an evolution of the mechanisms that combine math arrows with text. From
+the users perspective there is not that much difference with the old methods
+because in practice \quote {defined} commands are used and their name stayed.
+However, we use different definition and setup commands and provide much more
+control. The new implementation is leaner but not meaner and fits the way \MKIV\
+is set up.
+
+How does \LUA\ fits in? We use a helper in order to determine some
+characteristics of extensibles, but we could have done without. We also use some
+new \LUATEX\ math primitives and of course we depend on \OPENTYPE\ font
+technoloygy.
+
+\stopsection
+
+\startsection[title=Extensibles]
+
+The command \type {\leftarrowfill} was introduced in plain \TEX\ and gives, as
+the name indicates, a \leftarrowfill\ that stretches itself so that it takes the
+available space. Take the following example:
+
+\starttyping
+\hbox to 4cm{\leftarrowfill}
+\stoptyping
+
+This will make an arrow of length 4cm:
+
+\blank \mathstylehbox{\Umathaccent\fam\zerocount"2190{\hskip4cm}} \blank
+
+This arrow is made out of small snippets:
+
+\blank {\showglyphs\scale[width=\textwidth]{\mathstylehbox{\Umathaccent\fam\zerocount"2190{\hskip4cm}}}} \blank
+
+Here is another one:
+
+\starttyping
+\hbox to 4cm{\rightoverleftarrowfill}
+\stoptyping
+
+or:
+
+\blank {\mathstylehbox{\Umathaccent\fam\zerocount"21C4{\hskip4cm}}} \blank
+
+This time we have three different snippets:
+
+\blank {\showglyphs\scale[width=\textwidth]{\mathstylehbox{\Umathaccent\fam\zerocount"21C4{\hskip4cm}}}} \blank
+
+The \TEX\ engine has a concept of extensible characters. In fact there are two
+mechanisms: there is a list of larger glyphs and when that list is exhausted
+larger characters can be constructed out of snippets. Examples are left and right
+fences in math like braces and brackets, and, also in math, some top and bottom
+accents.
+
+For reasons unknown to me, some of these extensibles are handled by the engine
+directly, using properties of a font, while others are composed using macros.
+Given that \TEX\ is quite popular for typesetting scientific articles it is
+beyond my understanding why no one decided to provide some more fonts and|/|or
+extend the \TEX\ engine. After all, the whole idea of Donald Knuth with \TEX\ was
+that it could be adapted to future needs by its users. And so, more that 30 years
+after \TEX\ and macro packages showed up we're stuck with not only incomplete
+fonts, but also an engine that was never adapted to demands.
+
+\stopsection
+
+\startsection[title=The traditional way]
+
+In \CONTEXT\ we have support for extensibles built into the core but it uses the
+traditional approach: take some snippets and paste them together, making sure to
+achieve some overlap and get rid of side bearings. In terms of \TEX\ code this can
+best be illustrated with the plain \TEX\ definition of such a command:
+
+\starttyping
+\def\leftarrowfill
+  {$%
+   \mathsurround0pt%
+   \mathord\leftarrow\mkern-7mu%
+   \cleaders\hbox{$\mkern-2mu\smash-\mkern-2mu$}\hfill
+   \mkern-7mu\smash-%
+   $}
+\stoptyping
+
+Here we create a tight formula starting with a \type {leftarrow}, ending with a
+minus sign and glued together with the number of minus signs that are needed to
+fill the available space. This macro eventually expands to something like this (a
+bit spaced out):
+
+\starttyping
+\def\leftarrowfill { $
+  % \leftarrow = \mathchardef\leftarrow="3220 in plain but in
+  % unicode it's character 0x2190 so we use that one here
+  \mathsurround=0pt
+  \mathord{\mathchar"2190}
+  \mkern-7mu
+  \cleaders
+   \hbox { $
+     \mkern-2mu
+     \mathchoice
+      {\setbox0\hbox{$\displaystyle     -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\textstyle        -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\scriptstyle      -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\scriptscriptstyle-$}\ht0=0pt\dp0=0pt\box0}
+     \mkern-2mu
+    $ }
+   \hfill
+  \mkern-7mu
+  \mathchoice
+   {\setbox0\hbox{$\displaystyle     -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\textstyle        -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\scriptstyle      -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\scriptscriptstyle-$}\ht0=0pt\dp0=0pt\box0}
+$ }
+\stoptyping
+
+If you look at the code you see a few hacks. First of all we see that we need to
+add kerns in order to make the symbols overlap. For the middle shapes this is
+understandable as there we don't want rounding errors to lead to gaps. Also,
+because the minus in Computer Modern (and therefore Latin Modern) has rounded
+tips, we need to make sure that we end up beyond the tips. Next we see two blobs
+of \type {mathchoice}. This primitive chooses one of the four variants and
+switches to the right math style. It packages the minus and smashes it. In our
+case smashing makes not much sense as the arrowhead has height and depth anyway,
+but it's a side effect of using general purpose macros that there can be some
+unneeded overhead.
+
+\blank
+\hbox \bgroup \quad
+    \scale[sx=5,sy=5]{\hbox{\showglyphs$\mathsurround\zeropoint\char"2190$}}\quad
+    \scale[sx=5,sy=5]{\hbox{\showglyphs$\mathsurround\zeropoint\char"002D$}}\quad

+\egroup
+\blank
+
+Above you see the two characters that traditionally are combined into a leftward
+pointing arrows. Watch the whitespace on the left and right of the actual glyph.
+
+\stopsection
+
+\startsection[title=The new way]
+
+These zero height and depth don't show up in our rendered examples. Why is this?
+The reason is that I cheated a bit. I used this to get the arrow: \footnote {In
+this example I misuse the accent placement mechanism. Upto \LUATEX\ 0.75 that was
+the way to go.}
+
+\starttyping
+\mathstylehbox{\Umathaccent\fam\zerocount"21C4{\hskip4cm}}
+\stoptyping
+
+The \CONTEXT\ support macro \type {\mathstylehbox} is an efficient variant of
+\type {\mathchoice}. More significant is that we don't assemble the arrow, but
+just put it as an accent on top of a skip. The \type {\Umathaccent} primitive
+will assemble the long arrow for us, using information in the font. If we look
+into the definition of the (Latin Modern) font in \MKIV\ we see this:
+
+\starttyping
+[8592]={
+ ["boundingbox"]={ 57, -10, 942, 510 },
+ ["class"]="base",
+ ["index"]=1852,
+ ["math"]={
+  ["horiz_parts"]={
+   {
+    ["advance"]=507,
+    ["end"]=169,
+    ["extender"]=0,
+    ["glyph"]=984274,
+    ["start"]=0,
+   },
+   {
+    ["advance"]=337,
+    ["end"]=337,
+    ["extender"]=1,
+    ["glyph"]=984275,
+    ["start"]=337,
+   },
+   {
+    ["advance"]=507,
+    ["end"]=0,
+    ["extender"]=0,
+    ["glyph"]=984276,
+    ["start"]=169,
+   },
+  },
+  ["horiz_variants"]={ 10229 },
+ },
+ ["name"]="arrowleft",
+ ["width"]=1000,
+}
+\stoptyping
+
+This arrow symbol comes in two sizes. The extra size is mentioned in \type
+{horiz_variants}. When no more variants are seen, it switches to the extensible
+definition, that uses \type {horiz_parts}. The dimensions are in basepoints, the
+references to glyphs are decimal. The \type {end} and \type {start} fields
+specify the overlap. When \type {extender} equals 1 it signals a repeatable
+snippet.
+
+In the \TEX\ engine the slot allocated for the left arrow symbol has a \type
+{next} pointer to a larger shape. Here there is only one such shape but when
+there are more they form a linked list. The the last one in such a list gets the
+specification of the extenders.
+
+We hard|-|coded the width to 4cm so how does it work when the arrow has to adapt
+itself? There are two cases there. When we are putting text on top of or below an
+arrow, we know what the width is because we can measure the text. But when we use
+the arrow as a filler, we have to leave it to the engine to arrange it. In recent
+\LUATEX\ the definition can be as simple as:
+
+\starttyping
+\def\leftarrowfill{\leaders "2190 \hfill}
+\stoptyping
+
+or:
+
+\starttyping
+\def\leftarrowfill{\mathstylehbox{\leaders"2190\hfill}}
+\stoptyping
+
+In fact, we can use this new \LUATEX\ extension to \type {\leaders} to
+replace the accent hacks as well.
+
+\stopsection
+
+\startsection[title=Wrapping it in macros]
+
+If this was all, we would be done in a few lines of definitions but as usual
+there is more involved: especially text. The prerequisites can be summarized as
+follows:
+
+\startitemize[packed]
+\startitem
+    The width of the extensible need to adapt itself automatically.
+\stopitem
+\startitem
+    We need to be able to control horizontal and vertical offsets.
+\stopitem
+\startitem
+    We best have a math as well as a text variant (which is handy for chemistry).
+\stopitem
+\startitem
+    For historic reasons we need to deal with optional arguments in a special
+    (reverse) way.
+\stopitem
+\startitem
+    We need alternatives for extensibles on top, in the middle and at the bottom.
+\stopitem
+\stopitemize
+
+Using a low level command we can do this:
+
+\startbuffer[math]
+$x \directmathextensible{"2192}{top}{bottom} x$
+\stopbuffer
+
+\typebuffer[math] \blank \getbuffer[math] \blank
+
+This is not that exiting too look at, but the next might be:
+
+\enabletrackers[math.stackers.texts]
+
+\blank \getbuffer[math] \blank
+
+Here we have turned on a tracker:
+
+\starttyping
+\enabletrackers[math.stackers.texts]
+\stoptyping
+
+The toppart is transparent blue, the middlepart transparent red and the bottom
+part becomes transparent green. When the areas overlap you see the mixed color.
+
+Before we explore some options, we show some variants. Often extensibles are used
+in math mode, if only because they originate in math and come from math fonts.
+
+\startbuffer[text]
+$x \textstacker{"2192}{top}{bottom} x$
+\stopbuffer
+
+\typebuffer[text] \blank \getbuffer[text] \blank
+
+These commands also work outside math mode:
+
+\startbuffer[none]
+x \textstacker{"2192}{top}{bottom} x
+\stopbuffer
+
+\typebuffer[none] \blank \getbuffer[none] \blank
+
+and to some extend can adapt themselves:
+
+\startbuffer[high]
+x\high{x \textstacker{"2192}{top}{bottom} x} x
+\stopbuffer
+
+\typebuffer[high] \blank[2*big] \getbuffer[high] \blank
+
+\stopsection
+
+\startsection[title=Influencing the spacing]
+
+We will use the text example to illustrate some options.
+
+\startbuffer[demo]
+\ruledhbox \bgroup \quad
+    \setupmathstackers[location=top]%
+    \textstacker{"21C4}{top}{bottom}\quad
+    \setupmathstackers[location=high]%

+    \setupmathstackers[location=low]%
+    \textstacker{"21C4}{top}{bottom}\quad
+    \setupmathstackers[location=bottom]%
+    \textstacker{"21C4}{top}{bottom}\quad
+\egroup
+\stopbuffer
+
+\typebuffer[demo]
+
+You can set up extensibles to be shifted up and down.
+
+\blank \getbuffer[demo] \blank
+
+The above rendering uses the default spacing. When we set all values to zero we
+get this:
+
+\startbuffer[setup]
+\setupmathstackers
+  [voffset=\zeropoint,
+   hoffset=\zeropoint,
+   minheight=\exheight,
+   mindepth=\zeropoint,
+   minwidth=\zeropoint]
+\stopbuffer
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+The setup looks like this:
+
+\typebuffer[setup]
+
+and gives a pretty tight rendering. The default values are:
+
+\starttyping
+\setupmathstackers
+  [voffset=.25\exheight,
+   hoffset=.5\emwidth,
+   minheight=\exheight,
+   mindepth=\zeropoint,
+   minwidth=\emwidth]
+\stoptyping
+
+\startbuffer[setup]
+\setupmathstackers
+  [voffset=2\exheight,
+   hoffset=\emwidth,
+   minheight=\exheight,
+   mindepth=\zeropoint,
+   minwidth=\zeropoint]
+\stopbuffer
+
+When we set \type {voffset} to twice the ex|-|height and \type {hoffset} to
+the em|-|width we get:
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+We can enforce a (consistent) height and depth of the extensible by setting the
+minimum values:
+
+\startbuffer[setup]
+\setupmathstackers
+  [voffset=\zeropoint,
+   hoffset=\zeropoint,
+   minheight=5\exheight,
+   mindepth=3\exheight,
+   minwidth=6\emwidth]

+
+\typebuffer
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+\stopsection
+
+\startsection[title=A neat feature]
+
+A more obscure feature relates to the visual appearance. When we put something
+on top of for instance an arrow, it sometimes looks better when we only consider
+the middle part. Watch the following:
+
+\startbuffer[setup]
+\setupmathstackers
+  [voffset=\zeropoint,
+   hoffset=\zeropoint,
+   minheight=\zeropoint,
+   mindepth=\zeropoint,
+   minwidth=\zeropoint]

+    \setupmathstackers[offset=max]%
+    \textstacker{"21C4}{top}{bottom}\quad
+\egroup
+\stopbuffer
+
+\typebuffer[demo]
+
+The \type {min} and \type {max} values will add extra offsets that relate to the
+width of the edge snippets.
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+In this case both have the same result but the difference becomes clear when we
+set the \type {hoffset} to the em|-|width. In the case of \type {min} we don't
+add some extra space if the \type {hoffset} is applied.
+
+\startbuffer[setup]
+\setupmathstackers
+  [voffset=\zeropoint,
+   hoffset=\emwidth,
+   minheight=\zeropoint,

+\stopsection
+
+\startsection[title=The user interface]
+
+It all starts out with categories. We have a couple of predefined categories in
+the core. The \type {mathematics} category typesets the top and bottom texts in
+mathmode, while the \type {text} category doesn't. The \type {reverse} category
+swaps its arguments. There are \type {upper} and \type {under} categories too.
+
+As with most \CONTEXT\ mechanisms inheritance is part of the picture:
+
+\starttyping
+\definemathextensibles [mine] [big] [offset=min]
+\stoptyping
+
+You can change settings with:
+
+\starttyping
+\setupmathstackers [mine] [big] [voffset=\exheight]
+\stoptyping
+
+For downward compatibility we also provide these:
+
+\starttyping
+\definemathextensibles [normal] [hoffset=0.5\emwidth]
+\definemathextensibles [none]   [hoffset=\zeropoint]
+\definemathextensibles [small]  [hoffset=1\emwidth]
+\definemathextensibles [medium] [hoffset=1.5\emwidth]
+\definemathextensibles [big]    [hoffset=2\emwidth]
+\stoptyping
+
+They inherit from \type {mathematics} so choosing this also forces the top and
+bottomtexts to be typeset in math mode.
+
+These commands don't define extensibles, they only provide a way to categorize
+them. There are couple of definers and one reason for that is that we want to
+define downward compatible commands.
+
+\starttyping
+\definemathextensible [reverse] [xleftarrow]  ["2190]
+\definemathextensible [reverse] [xrightarrow] ["2192]
+\stoptyping
+
+The \type {x} in the name is sort of standard for an extensible symbol with
+optionally some text on top or below. The reverse forced compatible behaviour.
+
+\startbuffer
+\xrightarrow{stuff below} {stuff on top} \quad
+\xrightarrow{stuff on top}               \quad
+\xrightarrow{}            {stuff on top} \quad
+\xrightarrow{stuff below} {}             \quad
+\xrightarrow{}            {}             \quad
+\xrightarrow                             \quad
+\stopbuffer
+
+\typebuffer \getbuffer
+
+New in \MKIV\ is the \type {t} variant that typesets the text as (indeed) text.
+In addition we have a normal|-|order \type {m} variant:
+
+\starttyping
+\definemathextensible [text] [tleftarrow]  ["2190]
+\definemathextensible [text] [trightarrow] ["2192]
+
+\definemathextensible [mathematics] [mleftarrow]  ["2190]
+\definemathextensible [mathematics] [mrightarrow] ["2192]
+\stoptyping
+
+This time the order is always top first and bottom next:
+
+\startbuffer
+\trightarrow{stuff on top} {stuff below} \quad
+\trightarrow{stuff on top} {}            \quad
+\trightarrow{stuff on top}               \quad
+\trightarrow{}             {stuff below} \quad
+\trightarrow                             \quad
+\stopbuffer
+
+\typebuffer
+
+So we get:
+
+\getbuffer
+
+As you can see, there is an optional first argument that specifies the category
+that applies. This permits you to define extra commands that have their own
+(spacing) properties.
+
+Earlier on we saw that defined commands can be forced into a category:
+
+\startbuffer
+\trightarrow[big]   {stuff on top} {stuff below} \quad
+\trightarrow[medium]{stuff on top} {stuff below} \quad
+\trightarrow[small] {stuff on top} {stuff below}
+\stopbuffer
+
+\typebuffer
+
+Here we get:
+
+\getbuffer
+
+A variation on this kind of extensibles are over- and underarrows. This time the
+text is the nucleus.
+
+\starttyping
+\definemathoverextensible  [top]    [overleftarrow]   ["2190]
+\definemathoverextensible  [top]    [overrightarrow]  ["2192]
+
+\definemathunderextensible [bottom] [underleftarrow]  ["2190]
+\definemathunderextensible [bottom] [underrightarrow] ["2192]
+\stoptyping
+
+In action this looks like:
+
+\startbuffer
+\ruledhbox \bgroup $ \quad
+     \overleftarrow {a}  \quad    \overleftarrow {ABC}  $ \quad
+  x_{\overleftarrow {a}} \quad x_{\overleftarrow {ABC}} $ \quad
+     \underleftarrow{a}  \quad    \underleftarrow{ABC}  $ \quad
+  x_{\underleftarrow{a}} \quad x_{\underleftarrow{ABC}} $ \quad
+$ \egroup
+\stopbuffer
+
+\typebuffer
+
+Here we also have tracing enabled, and we also show the bounding box:
+
+\blank \getbuffer \blank
+
+This leaves us one command: the one that defines the basic filler:
+
+\starttyping
+\definemathextensiblefiller [leftarrowfill]  ["2190]
+\definemathextensiblefiller [rightarrowfill] ["2192]
+\stoptyping
+
+Commands defined like this will stretch themselves to fit the circumstances,
+and normally they will fill op the available space.
+
+\startbuffer
+\hbox to 4cm {from here \leftarrowfill\ to there}
+\hbox to 8cm {from there \rightarrowfill\ to here}
+\stopbuffer
+
+\typebuffer
+
+These commands (like the others) work in text mode as well as in math mode.
+
+\blank \getbuffer \blank
+
+\stopsection
+
+\startsection[title=Special cases]
+
+One of the reasons why the arrows mechanism has always been somewhat
+configureable is that we need arrows in the chemistry code.
+
+\starttyping
+\definemathextensibles
+  [chemistry]
+  [offset=max,
+   left=\enspace,
+   right=\enspace,
+   hoffset=.5\emwidth]
+
+\definemathextensible [chemistry] [cleftarrow]          ["2190]
+\definemathextensible [chemistry] [crightarrow]         ["2192]
+\definemathextensible [chemistry] [crightoverleftarrow] ["21C4]
+\stoptyping
+
+\startbuffer
+2H + O \crightarrow{explosive}\ H\low{2}O
+\stopbuffer
+
+\typebuffer
+
+Of course normally such code is wrapped into the chemistry enviroments and
+support macros.
+
+\blank \getbuffer \blank
+
+If you want something else than an extensible you can use definitions like the
+following:
+
+\startbuffer
+\definemathtriplet [tripleta]
+\definemathtriplet [text] [tripletb]
+\definemathtriplet [text] [tripletc] [\otimes]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\tripleta{\ominus}{top}{botom} and
+\tripletb{\oplus} {top}{botom} and
+\tripletc         {top}{botom}
+\stopbuffer
+
+\typebuffer
+
+\blank \hbox{\getbuffer} \blank
+
+As optional first argument you can pass a category.
+
+\startbuffer
+\tripleta[mathematics]{\ominus}{top}{botom} and
+\tripletb[mathematics]{\oplus}{top}{botom} and
+\tripletc[mathematics]{top}{botom}
+\stopbuffer
+
+\typebuffer
+
+Which gives:
+
+\blank \hbox{\getbuffer} \blank
+
+Instead of \type {mathematics} you could have given its synonym \type {math}.
+Keep in mind that categories are shared among stackers. There is also a direct
+command:
+
+\starttyping
+before \mathtriplet{\otimes}{top}{botom} after
+\stoptyping
+
+\stopsection
+
+\startsection[title=An overview]
+
+We end with showing a list of extensibles that come with the font used here, the
+\TEX Gyre Pagella. First we load a module:
+
+\startbuffer
+\usemodule[s][math-extensibles]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This module provides a couple of commands that typesets a table with the
+extensibles as known in \CONTEXT. Beware: not all fonts have all those
+characters.
+
+\startbuffer
+\showmathextensibles[alternative=a]
+\stopbuffer
+
+A second command is:
+
+\typebuffer
+
+This commands shows the base glyph, and the stretched variant with text on top
+and below. When no symbol is found in the font a rule is rendered.
+
+\getbuffer
+
+\startbuffer
+\showmathextensibles[alternative=b]
+\stopbuffer
+
+\typebuffer
+
+This command typesets a list with \UNICODE\ entries and defined commands. There
+are empty entries due to lack of glyphs in the used font. Not all characters have
+an associated command. Some have multiple commands with different math classes.
+
+\getbuffer
+
+\stopsection
+
+\startsection[title=Remark]
+
+The number of extensions to the \LUATEX\ core math engine is not that large and
+mostly involves more control over spacing and support for \UNICODE\ math as
+\OPENTYPE\ math extensibles. However, a few years after writing this chapter the
+machinery was cleaned up a bit and in the process some more control was added to
+constructors for radicals, fractions and delimiters. The spacing and composition
+can be controlled in a bit more detail using keywords (and dimensions). Because
+in \CONTEXT\ we already have mechanisms in place not much of that new
+functionality is used (yet). Also, in the meantime \CONTEXT\ evolved further.
+This chapter is just a snapshot and it might even render a bit different in more
+recent versions of \CONTEXT\ and|/|or \LUATEX. After all, it was written as part
+of the development story.

+
+\startsection[title=Introduction]
+
+Because \CONTEXT\ is often considered somewhat less math savvy than for instance
+\LATEX\ we have more freedom to experiment with new insights and move forward. Of
+course \CONTEXT\ always could deal with math, and even provides rather advanced
+support when it comes to combining fonts, which at some point was needed for a
+magazine that used two completely different sets of fonts in one issue. Also,
+many of the mechanisms had ways to influence the rendering, but often by means of
+constants and flags.
+
+Already in an early stage of \LUATEX\ we went \UNICODE\ and after that the low
+level code has been cleaned up stepwise. In fact, we probably have less code now
+than before because we need less hacks. Well, this might not be that true, if we
+consider that we also introduced code at the \LUA\ end which wasn't there before,
+but which makes makes support easier.
+
+Because we don't need to support all kind of third party math extensions that
+themselves might depend on overloading low level implementations, we can
+rigourously replace mechanisms. In the process we also make things easier to
+configure, easier to define and we promote some previously low level tuning
+options at the user level.
+
+Or course, by introducing new features and more options, there is a price to pay
+in terms of speed, but in practice users will seldom use the more complex
+constructs thousands of times in one document. Elsewhere arrows and alike were
+discussed, here I will spend some words on math styles and will use fences and
+fractions as an example as these mechanisms were used to experiment.
+
+\stopsection
+
+\startsection[title=Math styles]
+
+In \TEX\ a formula can used three different sizes of a font: text, script and
+scriptscript. In addition a formula can be typeset using rules for display math
+or rules for inline math. This means that we have the following so called math
+styles:
+
+\starttabulate[||||]
+% \FL
+\NC \bf keyword         \NC \bf meaning               \NC \bf command                \NC \NR
+% \FL
+\NC \type{display}      \NC used for display math     \NC \type {\displaystyle}      \NC \NR
+\NC \type{text}         \NC used for inline math      \NC \type {\textstyle}         \NC \NR
+\NC \type{script}       \NC smaller than text style   \NC \type {\scriptstyle}       \NC \NR
+\NC \type{scriptscript} \NC smaller than script style \NC \type {\scriptscriptstyle} \NC \NR
+% \LL
+\stoptabulate
+
+Each of these commands will force a style but in practice you seldom need to do
+that because \TEX\ does it automatically. In addition there is are cramped styles
+with corresponding commands.
+
+\starttabulate
+  \NC \ruledhbox{$\displaystyle             x^2 + \sqrt{x^2+2x} + \sqrt{\displaystyle             x^2+2x}$} \NC \type{\displaystyle            } \NC \NR

+  \NC \ruledhbox{$\crampedtextstyle         x^2 + \sqrt{x^2+2x} + \sqrt{\crampedtextstyle         x^2+2x}$} \NC \type{\crampedtextstyle        } \NC \NR
+  \NC \ruledhbox{$\scriptstyle              x^2 + \sqrt{x^2+2x} + \sqrt{\scriptstyle              x^2+2x}$} \NC \type{\scriptstyle             } \NC \NR
+  \NC \ruledhbox{$\crampedscriptstyle       x^2 + \sqrt{x^2+2x} + \sqrt{\crampedscriptstyle       x^2+2x}$} \NC \type{\crampedscriptstyle      } \NC \NR
+  \NC \ruledhbox{$\scriptscriptstyle        x^2 + \sqrt{x^2+2x} + \sqrt{\scriptscriptstyle        x^2+2x}$} \NC \type{\scriptscriptstyle       } \NC \NR
+  \NC \ruledhbox{$\crampedscriptscriptstyle x^2 + \sqrt{x^2+2x} + \sqrt{\crampedscriptscriptstyle x^2+2x}$} \NC \type{\crampedscriptscriptstyle} \NC \NR
+\stoptabulate
+
+Here we applied the styles as follows:
+
+\startbuffer
+$\textstyle x^2 + \sqrt{x^2+2x} + \sqrt{\textstyle x^2+2x}$
+\stopbuffer
+
+\typebuffer
+
+The differences are subtle: the superscripts in the square root are positioned a
+bit lower than normal: the radical forces them to be cramped.
+
+\startlinecorrection
+\scale[width=\hsize]{\maincolor \getbuffer}
+\stoplinecorrection
+
+Although the average user will not bother about styles, a math power user might
+get excited about the possibility to control the size of fonts being used, of
+course wit the danger of creating a visually inconsistent document. And, as in
+\CONTEXT\ we try to avoid such low level commands \footnote {Although \unknown\
+it's pretty hard to convince users to stay away from \type {\vskip} and friends.}
+it will be no surprise that we have ways to set them beforehand.
+
+\startbuffer
+\definemathstyle[mystyle][scriptscript]
+
+$ 2x + \startmathstyle [mystyle] 4y^2 \stopmathstyle = 10 $
+\stopbuffer
+
+\typebuffer
+
+So, if you want it this ugly, you can get it:
+
+\blank \start \getbuffer \stop \blank
+
+A style can be a combination of keywords. Of course we have \type {display},
+\type {text}, \type {script} and \type {scriptscript}. Then there are \type
+{uncramped} and \type {cramped} along with their synonyms \type {normal} and
+\type {packed}. In some cases you can also use \type {small} and \type {big}
+which will promote the size up or down, relative to what we have currently.
+
+A style definition can be combination of such keywords:
+
+\starttyping
+\definemathstyle[mystyle][scriptscript,cramped]
+\stoptyping
+
+Gradually we will introduce the \type {mathstyle} keyword in math related
+setups commands.
+
+In most cases a user will limit the scope of some setting by using braces, like
+this:
+
+\startbuffer
+$x{\setupmathstyle[script]x}x$
+\stopbuffer
+
+This gives {\maincolor \ignorespaces \getbuffer \removeunwantedspaces}: a smaller
+symbol between two with text size. Equally valid is this:
+
+\startbuffer
+$x\startmathstyle[script]x\stopmathstyle x$
+\stopbuffer
+
+\typebuffer
+
+Again we get {\maincolor \ignorespaces \getbuffer \removeunwantedspaces}, but at
+the cost of more verbose coding.
+
+The use of \type {{}} (either or not hidden in commands) has a few side effects.
+In text mode, when we use this at the start of a paragraph, the paragraph will
+start inside the group and when we end the group, specific settings that were
+done at that time get lost. So, in practice you will force a paragraph outside
+the group using \type {\dontleavehmode}, \type {\strut}, or one of the
+indentation commands. \stopitem
+
+In math mode a new math group is created which limits local style settings to
+this group. But as such groups also can trigger special kinds of spacing you
+sometimes don't want that. One pitfall is then to do this:
+
+\startbuffer
+$x\begingroup\setupmathstyle[script]x\endgroup x$
+\stopbuffer
+
+\typebuffer
+
+Alas, now we get {\maincolor \ignorespaces \getbuffer \removeunwantedspaces}. A
+\type {\begingroup} limits the scope of many things but it will not create a math
+group! This kind of subtle issues is the reason why we have pre|-|built solutions
+that take care of style switching, grouping, spacing and positioning.
+
+\stopsection
+
+\startsection[title=Fences]
+
+Fences are symbols at the left and right of an expression: braces, brackets,
+curly braces, and bars are the most well known. Often they are supposed to adapt
+their size to the content that they wrap. Here you see some in action:

+
+Often authors like to code their math with minimal structure and if you use
+\UNICODE\ characters that is actually quite doable. Just look at the double bar
+in the example above: if we input \type {||} we don't get what we want, but with
+\type {‖} the result is okay. This is because the \type {\left} and \type
+{\right} commands expect one character. But, even then, coding a bit more
+verbose sometimes makes sense.
+
+In stock \CONTEXT\ we have a couple of predefined fences:
+
+\starttyping
+\definemathfence [parenthesis] [left=0x0028,right=0x0029]
+\definemathfence [bracket]     [left=0x005B,right=0x005D]
+\definemathfence [braces]      [left=0x007B,right=0x007D]
+\definemathfence [bar]         [left=0x007C,right=0x007C]
+\definemathfence [doublebar]   [left=0x2016,right=0x2016]
+\definemathfence [angle]       [left=0x003C,right=0x003E]
+\stoptyping
+
+\startbuffer
+test $a \fenced[bar]      {\frac{1}{b}} c$ test
+test $a \fenced[doublebar]{\frac{1}{b}} c$ test
+test $a \fenced[bracket]  {\frac{1}{b}} c$ test
+\stopbuffer
+
+You use these by name:
+
+\typebuffer
+
+and get
+
+\startlines \getbuffer \stoplines
+
+\startbuffer
+\definemathfence [nooffence] [left=0x005B]
+\stopbuffer
+
+You can stick to only one fence:
+
+\typebuffer \getbuffer
+
+\startbuffer
+on $a \fenced[nooffence]{\frac{1}{b}} c$ off
+\stopbuffer
+
+Here \CONTEXT\ will take care of the dummy fence that \TEX\ expects instead.
+
+\startlines \getbuffer \stoplines
+
+You can define new fences and clone existing ones. You can also assign some
+properties:
+
+\startbuffer
+\definemathfence
+  [fancybracket]
+  [bracket]
+  [command=yes,
+   color=blue]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+test $a\fancybracket{\frac{1}{b}}c$ test
+test \color[red]{$a\fancybracket{\frac{1}{b}}c$} test
+\stopbuffer
+
+\typebuffer
+
+The color is only applied to the fence. This makes sense as the formula can
+follow the main color but influencing the fences is technically somewhat more
+complex.
+
+\getbuffer
+
+Here are some more examples:
+
+\startbuffer
+\definemathfence
+  [normalbracket]
+  [bracket]
+  [command=yes,
+   color=blue]
+
+\definemathfence
+  [scriptbracket]
+  [normalbracket]
+  [mathstyle=script]
+
+\definemathfence
+  [smallbracket]
+  [normalbracket]
+  [mathstyle=small]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\starttabulate
+\NC \type{$a                \frac{1}{b} c$}  \NC $a                \frac{1}{b}  c$ \NC \NR
+\TB
+\NC \type{$a \normalbracket{\frac{1}{b} c$}} \NC $a \normalbracket{\frac{1}{b}} c$ \NC \NR
+\TB
+\NC \type{$a \scriptbracket{\frac{1}{b} c$}} \NC $a \scriptbracket{\frac{1}{b}} c$ \NC \NR
+\TB
+\NC \type{$a \smallbracket {\frac{1}{b} c$}} \NC $a \smallbracket {\frac{1}{b}} c$ \NC \NR
+\stoptabulate
+
+As with most commands, the fences inherit from the parents so we can say:
+
+\starttyping
+\setupmathfences [color=red]
+\stoptyping
+
+and get all our fences colored red. The \type {command} option results in a
+command being defined, which saves you some keying.
+
+\stopsection
+
+\startsection[title=Fractions]
+
+In \TEX\ the mechanism to put something on top of something else, separated by a
+horizontal rule, is driven by the \type {\over} primitive. That one has a
+(compared to other commands) somewhat different specification, in the sense that
+one of its arguments sits in front:
+
+\starttyping
+$ {{2x}\over{x^1}} $
+\stoptyping
+
+Although to some extend this is considered to be more readable, macro packages
+often provide a \type {\frac} commands that goes like this:
+
+\starttyping
+$ \frac{2x}{x^1} $
+\stoptyping
+
+There we have less braces and the arguments come after the command. As with the
+fences in the previous section, you can define your own fractions:
+
+\startbuffer
+\definemathfraction
+  [innerfrac]
+  [frac]
+  [alternative=inner,
+   mathstyle=script,
+   color=red]
+
+\definemathfraction
+  [outerfrac]
+  [frac]
+  [alternative=outer,
+   mathstyle=script,
+   color=blue]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The mathstyle and color are already discussed but the \type {alternative} is
+specific for these fractions. It determines if the style is applied to the whole
+fraction or to its components.
+
+\startbuffer
+\startformula
+\outerfrac{2a}{3b} = \innerfrac{2a}{3b} = \frac{2a}{3b}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+As with fences, the color is only applied to the horizontal bar as there is no
+other easy way to color that otherwise.
+
+\getbuffer
+
+As \TEX\ has a couple of low level stackers, we provide an interface to that as
+well, but we hide the dirty details. For instance you can define left and right
+fences and influence the rule
+
+\startbuffer
+\definemathfraction[fraca][rule=no,left=0x005B,right=0x007C]
+\definemathfraction[fracb][rule=yes,left=0x007B,right=0x007D]
+\definemathfraction[fracc][rule=auto,left=0x007C]
+\definemathfraction[fracd][rule=yes,rulethickness=2pt,left=0x007C]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+When \type {rule} is set to \type {auto}, we use \TEX's values (derived from font
+metrics) for the thickness of rules, while \type {yes} triggers usage of the
+specified \type {rulethickness}.
+
+\startbuffer
+\startformula
+\fraca{a}{b} + \fracb{a}{b} + \fracc{a}{b} + \fracd{a}{b}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+Gives:
+
+\getbuffer
+
+\startbuffer
+\definemathfraction
+  [frace]
+  [rule=yes,
+   color=blue,
+   rulethickness=1pt,
+   left=0x005B,
+   right=0x007C]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This fraction looks as follows (scaled up):
+
+\startlinecorrection
+\midaligned{\scale[height=5ex]{$\displaystyle\frace{a}{b}$}}
+\stoplinecorrection
+
+So, the color is applied to the (optional) fences as well as to the (optional)
+rule. And when you color the whole formula as part of the context, you get
+
+\startlinecorrection
+\midaligned{\scale[height=5ex]{\color[maincolor]{$\displaystyle\frace{a}{b}$}}}
+\stoplinecorrection
+
+There is a (maybe not so) subtle difference between fences that come with
+fractions and regular fences, Take these definitions:
+
+\startbuffer
+\definemathfence    [parenta] [left=0x28,right=0x29,command=yes]
+\definemathfraction [parentb] [left=0x28,right=0x29,rule=auto]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Of course the \type {b} variant takes less code:
+
+\startbuffer
+\startformula
+\parenta{\frac{a}{b}} + \parentb{a}{b}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+But watch how the parentheses are also larger. At some point \CONTEXT\ will
+provide a bit more control over this,
+
+\getbuffer
+
+You can also influence the width of the rule, but that is not related to the
+style.
+
+\startbuffer
+\definemathfraction
+  [wfrac]
+  [margin=.25em]
+
+\definemathfraction
+  [wwfrac]

+
+\startformula
+  \frac   {  a } { \frac {  b } {  c } } +
+  \wfrac  {  a } { \frac {  b } {  c } } =
+  \wwfrac { 2a } { \frac { 2b } { 2c } }
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+Both the nominator and denominator are widened by the margin:

+% Hans Hagen, PRAGMA ADE, April 2014
+
+\startsection[title=Introduction]
+
+Already for some years I have been wondering how it would be if we could escape
+to \LUA\ inside \METAPOST, or in practice, in \MPLIB\ in \LUATEX. The idea is
+simple: embed \LUA\ code in a \METAPOST\ file that gets run as soon as it's seen.
+In case you wonder why \LUA\ code makes sense, imagine generating graphics using
+external data. The capabilities of \LUA\ to deal with that is more flexible and
+advanced than in \METAPOST. Of course we could generate a \METAPOST\ definition
+of a graphic from data but it often makes more sense to do the reverse. I finally
+found time and reason to look into this and in the following sections I will
+describe how it's done.
+
+\stopsection
+
+\startsection[title=The basics]
+
+The approach is comparable to \LUATEX's \type {\directlua}. That primitive can be
+used to execute \LUA\ code and in combination with \type {tex.print} we can pipe
+strings back into the \TEX\ input stream. A complication is that we have to be
+able to operate under different so called catcode regimes: the meaning of
+characters can differ per regime. We also have to deal with line endings in
+special ways as they relate to paragraphs and such. In \METAPOST\ we don't have
+that complication so getting back input into the \METAPOST\ input, we can do so
+with simple strings. For that a mechanism similar to \type {scantokens} can be
+used. That way we can return anything (including nothing) as long as \METAPOST\
+can interpret it and as long as it fulfils the expectations.
+
+\starttyping
+numeric n ; n := scantokens("123.456") ;
+\stoptyping
+
+A script is run as follows:
+
+\starttyping
+numeric n ; n := runscript("return '123.456'") ;
+\stoptyping
+
+This primitive doesn't have the word \type {lua} in its name so in principle any
+wrapper around the library can use it as a hook. In the case of \LUATEX\ the
+script language is of course \LUA. At the \METAPOST\ end we only expect a string.
+How that string is constructed is completely up to the \LUA\ script. In fact, the
+user is completely free to implement the runner any way she or he wants, like:
+
+\starttyping
+local function scriptrunner(code)
+    local f = loadstring(code)
+    if f then
+        return tostring(f())
+    else
+        return ""
+    end
+end
+\stoptyping
+
+This is hooked into an instance as follows:
+
+\starttyping
+local m = mplib.new {
+    ...
+    run_script = scriptrunner,
+    ...
+}
+\stoptyping
+
+Now, beware, this is not the \CONTEXT\ way. We provide print functions and other
+helpers, which we will explain in the next section.
+
+\stopsection
+
+\startsection[title=Helpers]
+
+After I got this feature up and running I played a bit with possible interfaces
+at the \CONTEXT\ (read: \METAFUN) end and ended up with a bit more advanced runner
+where no return value is used. The runner is wrapped in the \type {lua} macro.
+
+\startbuffer
+numeric n ; n := lua("mp.print(12.34567)") ;
+draw textext(n) xsized 4cm withcolor maincolor ;
+\stopbuffer
+
+\typebuffer
+
+This renders as:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+In case you wonder how efficient calling \LUA\ is, don't worry: it's fast enough,
+especially if you consider suboptimal \LUA\ code and the fact that we switch
+between machineries.
+
+\startbuffer
+draw image (
+    lua("statistics.starttiming()") ;
+    for i=1 upto 10000 : draw
+        lua("mp.pair(math.random(-200,200),math.random(-50,50))") ;
+    endfor ;
+    setbounds currentpicture to fullsquare xyscaled (400,100) ;
+    lua("statistics.stoptiming()") ;
+    draw textext(lua("mp.print(statistics.elapsedtime())"))
+        ysized 50 ;
+) withcolor maincolor withpen pencircle scaled 1 ;
+\stopbuffer
+
+\typebuffer
+
+Here the line:
+
+\starttyping
+draw lua("mp.pair(math.random(-200,200),math.random(-50,50))") ;
+\stoptyping
+
+effectively becomes (for instance):
+
+\starttyping
+draw scantokens "(25,40)" ;
+\stoptyping
+
+which in turn becomes:
+
+\starttyping
+draw scantokens (25,40) ;
+\stoptyping
+
+The same happens with this:
+
+\starttyping
+draw textext(lua("mp.print(statistics.elapsedtime())")) ...
+\stoptyping
+
+This becomes for instance:
+
+\starttyping
+draw textext(scantokens "1.23") ...
+\stoptyping
+
+and therefore:
+
+\starttyping
+draw textext(1.23) ...
+\stoptyping
+
+We can use \type {mp.print} here because the \type {textext} macro can deal with
+numbers. The following also works:
+
+\starttyping
+draw textext(lua("mp.quoted(statistics.elapsedtime())")) ...
+\stoptyping
+
+Now we get (in \METAPOST\ speak):
+
+\starttyping
+draw textext(scantokens (ditto & "1.23" & ditto) ...
+\stoptyping
+
+Here \type {ditto} represents the double quotes that mark a string. Of course,
+because we pass the strings directly to \type {scantokens}, there are no outer
+quotes at all, but this is how it can be simulated. In the end we have:
+
+\starttyping
+draw textext("1.23") ...
+\stoptyping
+
+What print variant you use, \type {mp.print} or \type {mp.quoted}, depends on
+what the expected code is: an assignment to a numeric can best be a number or an
+expression resulting in a number.
+
+This graphic becomes:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The runtime on my current machine is some 0.25 seconds without and 0.12 seconds
+with caching. But to be honest, speed is not really a concern here as the amount
+of complex \METAPOST\ graphics can be neglected compared to extensive node list
+manipulation. Generating the graphic with \LUAJITTEX\ takes 15\% less time.
+\footnote {Processing a small 8 page document like this takes about one second,
+which includes loading a bunch of fonts.}
+
+\startbuffer
+numeric n ; n := lua("mp.print(1) mp.print('+') mp.print(2)") ;
+draw textext(n) xsized 1cm withcolor maincolor ;
+\stopbuffer
+
+The three print command accumulate their arguments:
+
+\typebuffer
+
+As expected we get:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+\startbuffer
+numeric n ; n := lua("mp.print(1,'+',2)") ;
+draw textext(n) xsized 1cm withcolor maincolor ;
+\stopbuffer
+
+Equally valid is:
+
+\typebuffer
+
+This gives the same result:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Of course all kind of action can happen between the prints. It is also legal to
+have nothing returned as could be seen in the 10.000 dot example: there the timer
+related code returns nothing, so effectively we have \type {scantokens("")}.
+Another helper is \type {mp.quoted}, as in:
+
+\startbuffer
+draw
+    textext(lua("mp.quoted('@0.3f'," & decimal n & ")"))
+    withcolor maincolor ;
+\stopbuffer
+
+\typebuffer
+
+This typesets \processMPbuffer. Note the \type {@}. When no percent character is
+found in the format specifier, we assume that an \type {@} is used instead.
+
+\startbuffer
+\startluacode
+table.save("demo-data.lua",
+    {
+        { 1, 2 }, { 2, 4 }, { 3, 3 }, { 4, 2 },
+        { 5, 2 }, { 6, 3 }, { 7, 4 }, { 8, 1 },
+    }
+)
+\stopluacode
+\stopbuffer
+
+But, the real benefit of embedded \LUA\ is when we deal with data that is stored
+at the \LUA\ end. First we define a small dataset:
+
+\typebuffer
+
+\getbuffer
+
+There are several ways to deal with this table. I will show clumsy as well as
+better looking ways.
+
+\startbuffer
+lua("MP = { } MP.data = table.load('demo-data.lua')") ;
+numeric n ;
+lua("mp.print('n := ',\#MP.data)") ;
+for i=1 upto n :
+    drawdot
+        lua("mp.pair(MP.data[" & decimal i & "])") scaled cm
+        withpen pencircle scaled 2mm
+        withcolor maincolor ;
+endfor ;
+\stopbuffer
+
+\typebuffer
+
+Here we load a \LUA\ table and assign the size to a \METAPOST\ numeric. Next we
+loop over the table entries and draw the coordinates.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+We will stepwise improve this code. In the previous examples we omitted wrapper
+code but here we show it:
+
+\startbuffer
+\startluacode
+    MP.data = table.load('demo-data.lua')
+    function MP.n()
+        mp.print(#MP.data)
+    end
+    function MP.dot(i)
+        mp.pair(MP.data[i])
+    end
+\stopluacode
+
+\startMPcode
+    numeric n ; n := lua("MP.n()") ;
+    for i=1 upto n :
+        drawdot
+            lua("MP.dot(" & decimal i & ")") scaled cm
+            withpen pencircle scaled 2mm
+            withcolor maincolor ;
+    endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+So, we create a few helpers in the \type {MP} table. This table is predefined so
+normally you don't need to define it. You may however decide to wipe it clean.
+
+\startlinecorrection[blank]
+\getbuffer
+\stoplinecorrection
+
+You can decide to hide the data:
+
+\startbuffer
+\startluacode
+    local data = { }
+    function MP.load(name)
+        data = table.load(name)
+    end
+    function MP.n()
+        mp.print(#data)
+    end
+    function MP.dot(i)
+        mp.pair(data[i])
+    end
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+It is possible to use less \LUA, for instance in:
+
+\startbuffer
+\startluacode
+    local data = { }
+    function MP.loaded(name)
+        data = table.load(name)
+        mp.print(#data)
+    end
+    function MP.dot(i)
+        mp.pair(data[i])
+    end
+\stopluacode
+
+\startMPcode
+    for i=1 upto lua("MP.loaded('demo-data.lua')") :
+        drawdot
+            lua("MP.dot(",i,")") scaled cm
+            withpen pencircle scaled 4mm
+            withcolor maincolor ;
+    endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+Here we also omit the \type {decimal} because the \type {lua} macro is clever
+enough to recognize it as a number.
+
+\startlinecorrection[blank]
+\getbuffer
+\stoplinecorrection
+
+By using some \METAPOST\ magic we can even go a step further in readability:
+
+\startbuffer
+\startMPcode{doublefun}
+    lua.MP.load("demo-data.lua") ;
+
+    for i=1 upto lua.MP.n() :
+        drawdot
+            lua.MP.dot(i) scaled cm
+            withpen pencircle scaled 4mm
+            withcolor maincolor ;
+    endfor ;
+
+    for i=1 upto MP.n() :
+        drawdot
+            MP.dot(i) scaled cm
+            withpen pencircle scaled 2mm
+            withcolor white ;
+    endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+Here we demonstrate that it also works well in \type {double} mode, which makes
+much sense when processing data from other sources. Note how we omit the
+type {lua.} prefix: the \type {MP} macro will deal with that.
+
+\startlinecorrection[blank]
+\getbuffer
+\stoplinecorrection
+
+So in the end we can simplify the code that we started with to:
+
+\starttyping
+\startMPcode{doublefun}
+    for i=1 upto MP.loaded("demo-data.lua") :
+        drawdot
+            MP.dot(i) scaled cm
+            withpen pencircle scaled 2mm
+            withcolor maincolor ;
+    endfor ;
+\stopMPcode
+\stoptyping
+
+\stopsection
+
+\startsection[title=Access to variables]
+
+The question with such mechanisms is always: how far should we go. Although
+\METAPOST\ is a macro language, it has properties of procedural languages. It also
+has more introspective features at the user end. For instance, one can loop over
+the resulting picture and manipulate it. This means that we don't need full
+access to \METAPOST\ internals. However, it makes sense to provide access to
+basic variables: \type {numeric}, \type {string}, and \type {boolean}.
+
+\startbuffer
+draw textext(lua("mp.quoted('@0.15f',mp.get.numeric('pi')-math.pi)"))
+    ysized 1cm
+    withcolor maincolor ;
+\stopbuffer
+
+\typebuffer
+
+In double mode you will get zero printed but in scaled mode we definitely get a
+different results:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+\startbuffer
+boolean b ; b := true ;
+draw textext(lua("mp.quoted(mp.get.boolean('b') and 'yes' or 'no')"))
+    ysized 1cm
+    withcolor maincolor ;
+\stopbuffer
+
+In the next example we use \type {mp.quoted} to make sure that indeed we pass a
+string. The \type {textext} macro can deal with numbers, but an unquoted \type
+{yes} or \type {no} is asking for problems.
+
+\typebuffer
+
+Especially when more text is involved it makes sense to predefine a helper in
+the \type {MP} namespace, if only because \METAPOST\ (currently) doesn't like
+newlines in the middle of a string, so a \type {lua} call has to be on one line.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Here is an example where \LUA\ does something that would be close to impossible,
+especially if more complex text is involved.

+    ...
+    script_runner = function(s) return loadstring(s)() end,
+    script_error  = function(s) print(s) end,

+\stoptyping
+
+An instance (in this case \type {m}) has a few extra methods. Instead you can use

+\starttabulate[|l|l|]

+\startsection[title=\CONTEXT\ helpers]
+
+The \type {mp} namespace provides the following helpers:

+\starttabulate[|l|l|]
+\HL
+\NC \type {print(...)}                \NC returns one or more values \NC \NR
+\NC \type {pair(x,y)}

+\NC \type {format(fmt,...)}           \NC returns a formatted string \NC \NR
+\NC \type {quoted(fmt,...)}

+\NC \type {path(t[,connect][,close])} \NC returns a connected (closed) path \NC \NR
+\HL
+\stoptabulate

+\NC \type {numeric(name)}      \NC gets a numeric from \METAPOST \NC \NR
+\NC \type {boolean(name)}      \NC gets a boolean from \METAPOST \NC \NR

+\startsection[title=Paths]
+
+% {\em This section will move to the metafun manual.} \blank
+
+In the meantime we got several questions on the \CONTEXT\ mailing list about turning
+coordinates into paths. Now imagine that we have this dataset:
+
+\startbuffer[dataset]
+10 20 20 20 -- sample 1
+30 40 40 60
+50 10
+
+10 10 20 30 % sample 2
+30 50 40 50
+50 20
+
+10 20 20 10 # sample 3
+30 40 40 20
+50 10
+\stopbuffer
+
+\typebuffer[dataset]
+
+In this case I have put the data in a buffer, so that it can be shown
+here, as well as used in a demo. Look how we can add comments. The
+following code converts this into a table with three subtables.
+
+\startbuffer
+\startluacode
+  MP.myset = mp.dataset(buffers.getcontent("dataset"))
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We use the \type {MP} (user) namespace to store the table. Next we turn
+these subtables into paths:
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.print(mp.n(MP.myset))") :
+    draw
+      lua("mp.path(MP.myset[" & decimal i & "])")
+      xysized (HSize,10ExHeight)
+      withpen pencircle scaled .25ExHeight
+      withcolor basiccolors[i]/2 ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+Instead we can fill the path, in which case we will also need to close it. The
+\type {true} argument deals with that:
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.print(mp.n(MP.myset))") :
+    path p ; p :=
+      lua("mp.path(MP.myset[" & decimal i & "],true)")
+      xysized (HSize,10ExHeight) ;
+    fill p
+      withcolor basiccolors[i]/2
+      withtransparency (1,.5) ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+We get:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.print(mp.n(MP.myset))") :
+    path p ; p :=
+      lua("mp.path(MP.myset[" & decimal i & "])")
+      xysized (HSize,10ExHeight) ;
+    p :=
+      (xpart llcorner boundingbox p,0) --
+      p --
+      (xpart lrcorner boundingbox p,0) --
+      cycle ;
+    fill p
+      withcolor basiccolors[i]/2
+      withtransparency (1,.25) ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+The following makes more sense:
+
+\typebuffer
+
+So this gives:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+This (area) fill is so common, that we have a helper for it:
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.size(MP.myset)") :
+    fill area
+      lua("mp.path(MP.myset[" & decimal i & "])")
+      xysized (HSize,5ExHeight)
+      withcolor basiccolors[i]/2
+      withtransparency (2,.25) ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+So this gives:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+This snippet of \METAPOST\ code still looks kind of horrible, so how can we make
+it look better? Here is an attempt. First we define a bit more \LUA:
+
+\startbuffer
+\startluacode
+local data = mp.dataset(buffers.getcontent("dataset"))
+
+MP.dataset = {
+  Line = function(n) mp.path(data[n]) end,
+  Size = function()  mp.size(data)    end,
+}
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua.MP.dataset.Size() :
+    path p ; p :=
+      lua.MP.dataset.Line(i)
+      xysized (HSize,20ExHeight) ;
+    draw
+      p
+      withpen pencircle scaled .25ExHeight
+      withcolor basiccolors[i]/2 ;
+    drawpoints
+      p
+      withpen pencircle scaled ExHeight
+      withcolor .5white ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+We can now make the \METAPOST\ look more natural. Of course, this is possible
+because in \METAFUN\ the \type {lua} macro does some extra work.
+
+\typebuffer
+
+As expected, we get the desired result:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+Once we start making things look nicer and more convenient, we quickly end up
+with helpers like those in the next example. First we save some demo data in
+files:
+
+\startbuffer
+\startluacode
+  io.savedata("foo.tmp","10 20 20 20 30 40 40 60 50 10")
+  io.savedata("bar.tmp","10 10 20 30 30 50 40 50 50 20")
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We load the data in datasets:
+
+\startbuffer
+\startMPcode
+  lua.mp.datasets.load("foo","foo.tmp") ;
+  lua.mp.datasets.load("bar","bar.tmp") ;
+  fill area
+    lua.mp.datasets.foo.Line()
+    xysized (HSize/2-EmWidth,10ExHeight)
+    withpen pencircle scaled .25ExHeight
+    withcolor green/2 ;
+  fill area
+    lua.mp.datasets.bar.Line()
+    xysized (HSize/2-EmWidth,10ExHeight)
+    shifted (HSize/2+EmWidth,0)
+    withpen pencircle scaled .25ExHeight
+    withcolor red/2 ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+Because the datasets are stored by name, we can use them without worrying about
+them being forgotten:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+If no tag is given, the filename (without suffix) is used as a tag, so the
+following is valid:
+
+\starttyping
+\startMPcode
+  lua.mp.datasets.load("foo.tmp") ;
+  lua.mp.datasets.load("bar.tmp") ;
+\stopMPcode
+\stoptyping
+
+The following methods are defined for a dataset:
+
+\starttabulate[|l|pl|]
+\HL
+\NC \type {method} \NC usage \NC \NR
+\HL
+\NC \type {Size}   \NC the number of subsets in a dataset \NC \NR
+\NC \type {Line}   \NC the joined pairs in a dataset making a non|-|closed path \NC \NR
+\NC \type {Data}   \NC the table containing the data (in subsets, so there is always at least one subset) \NC \NR
+\HL
+\stoptabulate
+
+{\em Due to limitations in \METAPOST\ suffix handling the methods start with an
+uppercase character.}
+
+\stopsection
+
+\startsection[title=Remark]
+
+The features described here are currently still experimental but the interface
+will not change. There might be a few more accessors and for sure more \LUA\
+helpers will be provided. As usual I need some time to play with it before I make
+up my mind. It is also possible to optimize the \METAPOST||\LUA\ script call a
+bit, but I might do that later.
+
+When we played with this interface we ran into problems with loop variables
+and macro arguments. These are internally kind of anonymous. Take this:
+
+\starttyping
+for i=1 upto 100 : draw(i,i) endfor ;
+\stoptyping
+
+The \type {i} is not really a variable with name \type {i} but becomes an object
+(capsule) when the condition is scanned, and a reference to that object when the
+body is scanned. The body of the for loop gets expanded for each step, but at that
+time there is no longer a variable \type {i}. The same is true for variables in:
+
+\starttyping
+def foo(expr x, y, delta) = draw (x+delta,y+delta) enddef ;
+\stoptyping
+
+We are still trying to get this right with the \LUA\ interface. Interesting is
+that when we were exploring this, we ran into quite some cases where we could
+make \METAPOST\ abort due some memory or stack overflow. Some are just bugs in
+the new code (due to the new number model) while others come with the design of
+the system: border cases that never seem to happen in interactive use while the
+library use assumes no interaction in case of errors.
+
+In \CONTEXT\ there are more features and helpers than shown here but these are
+discussed in the \METAFUN\ manual.

+\startsection[title=Introduction]
+
+At the 2013 \CONTEXT\ meeting in Breslov, Harald König has taken some of his
+gadgets with him and this time the target was to get \CONTEXT\ running on small
+devices, most noticeably a mobile phone. You may wonder what purpose this serves,
+but with such devices becoming more powerful each year, and desktops and laptops
+getting less popular, we might see the small devices taking their place.
+Especially when we can dock them in a cradle and connect them to a proper monitor
+and keyboard we might end up with universal devices. Combine that with projection
+on our retinas and less tactile input and it will be clear that we should at
+least look into this from the perspective of \TEX\ usage.
+
+\stopsection
+
+\startsection[title=The tests]
+
+We used five tests for measuring basic performance. Of course we made sure that
+binaries and resources were cached.
+
+Test 1 measures some basics, like typesetting a paragraph, flushing pages and
+loading a file. Because we do lots of pages we can also see if garbage collection
+is a problem.
+
+\typefile{pi-speed-1.tex}
+
+A normal \CONTEXT\ run is triggered with:
+
+\starttyping
+context speed-1
+\stoptyping
+
+but with
+
+\starttyping
+context --timing speed-1
+\stoptyping
+
+memory consumption is measured and one can generate a visual representation of
+this afterwards.
+
+\starttyping
+context --extra=timing speed-1
+\stoptyping
+
+We don't show them here, simply because we saw nothing exciting in the ones
+for these tests.
+
+The second test is rather stupid but it gives an indication of how efficient the
+base pagebuilder is:
+
+\typefile{pi-speed-2.tex}
+
+The numbers are normally 10 to 20 times more impressive than those for regular runs.
+
+Test three is a variation on test one but this time we avoid the file being read
+in many times, so we inline \type{ward.tex}. We also add no page breaks so we get
+less pages but with more content.
+
+\typefile{pi-speed-3.tex}
+
+The fourth test draws a few \METAPOST\ graphics, which themselves use a bit of
+typeset text.
+
+\typefile{pi-speed-4.tex}
+
+The last test, number five, is more demanding. Here we use some colors (which
+stresses the backend) and a dynamic switch to smallcaps, which puts a bit of a
+burden on the \OPENTYPE\ handler.
+
+\typefile{pi-speed-5.tex}
+
+\stopsection
+
+\startsection[title=Regular laptops]
+
+We started measuring on Haralds laptop, a Lenovo X201i, and got the following
+timings (that matched our expectations). The second column shows the runtime, the
+last column the pages per second.
+
+\starttabulate[|l|r|r|]
+\BC speed-1 \NC  5.8 \NC  17.1 \NC \NR
+\BC speed-2 \NC  3.6 \NC 275.6 \NC \NR
+\BC speed-3 \NC  5.1 \NC  19.8 \NC \NR
+\BC speed-4 \NC  0.6 \NC   1.8 \NC \NR
+\BC speed-5 \NC 11.9 \NC  10.6 \NC \NR
+\stoptabulate
+
+Just for comparison, as I'm wrapping this up in 2016, on my current Dell 7600 I
+get these timings (the last two columns are with \LUAJITTEX):
+
+\starttabulate[|l|r|r|r|r|]
+\BC speed-1 \NC  4.6 \NC  21.9 \NC 3.0 \NC  33.5 \NC \NR
+\BC speed-2 \NC  3.6 \NC 278.2 \NC 2.8 \NC 357.7 \NC \NR
+\BC speed-3 \NC  4.2 \NC  23.6 \NC 2,7 \NC  37.0 \NC \NR
+\BC speed-4 \NC  0.8 \NC   1.3 \NC 0.6 \NC   1.7 \NC \NR
+\BC speed-5 \NC  6.2 \NC  20.3 \NC 4.0 \NC  31.9 \NC \NR
+\stoptabulate
+
+These tests were run with a \LUATEX\ 0.98 and the most recent \CONTEXT\
+\OPENTYPE\ font processor. As we do more in \LUA\ that a few years back, one
+can't expect a much faster run, even when the Dell has a faster processor than
+the Lenovo. However, what gets noticed is that the fifth speed test runs about
+twice as fast which is mostly due to improvements in the handling of \OPENTYPE\
+features.
+
+\startsection[title=The Nexus IV]
+
+This mobile phone has a quad-core arm processor running at 1.5 GHz. With 2 Gb
+memory this should be sufficient for running \TEX. The operating system is
+Android, which means that some effort is needed to put \TEX\ with its resources
+on the internal flash disk. Access was remote from a laptop.
+
+\starttabulate[|l|r|r|]
+\BC speed-1 \NC 41.9 \NC  2.4 \NC \NR
+\BC speed-2 \NC 27.5 \NC 36.4 \NC \NR
+\BC speed-3 \NC 38.7 \NC  2.6 \NC \NR
+\BC speed-4 \NC  3.4 \NC  3.0 \NC \NR
+\BC speed-5 \NC 87.9 \NC  1.4 \NC \NR
+\stoptabulate
+
+So it looks like the phone runs these tests about five times slower than the
+laptop. The fifth test is most stressful on the hardware but as noted, a more
+recent \CONTEXT\ will give better times there due to improvements in feature
+processing.
+
+\stopsection
+
+\startsection[title=The Raspbery Pi]
+
+The Pi (we're talking of the first model here) has an extension bus and can be
+used to control whatever device, it has more the properties (and build) of a
+media player and indeed there are dedicated installations for that. But as this
+popular small device can host any \LINUX\ distribution this is what was done. The
+distribution of choice was OpenSuse. The setup was really experimental with an
+unboxed Pi, an unframed \LCD\ panel, a keyboard and mouse, a power supply and
+some wires to connect this all. With an ethernet cable running directly to the
+router a distribution could be fetched and installed.
+
+This device has a single core arm processor running at 700 Mhz with half a
+gigabyte of memory. Persistent memory is a flash card, not that fast but
+acceptable. The maximum read speed was some 20 MB per second. It was no real
+surprise that the set of tests ran much slower than on the phone.
+
+It took a bit of experimenting but a 200 Mhz overclock of the \CPU\ combined with
+overclocked memory made performance jump up. In fact, we got a speed that we
+could somehow relate to the phone that has a more modern \CPU\ and runs at 1.5
+times that speed.
+
+Being a regular \LINUX\ setup, installation was more straightforward than on the
+phone but of course it took a while before all was in place. The default clock
+timings are:
+
+\starttabulate[|l|r|r|]
+\BC speed-1 \NC  95.841 \NC  1.043 \NC \NR
+\BC speed-2 \NC  76.817 \NC 13.018 \NC \NR
+\BC speed-3 \NC  84.890 \NC  1.178 \NC \NR
+\BC speed-4 \NC  13.241 \NC  0.076 \NC \NR
+\BC speed-5 \NC 192.288 \NC  0.660 \NC \NR
+\stoptabulate
+
+Again, the main conclusion here is that documents that need lots of \OPENTYPE\
+feature juggling, this is not the best platform.
+
+\stopsection
+
+\startsection[title=Summary]
+
+We see small devices gaining more performance each iteration than larger
+machines. Their screens and input method also evolve at a higher speed. The
+question is if arm will keep dominating this segment, but at least it is clear
+that they are useable for \TEX\ processing. Keep in mind that we used \LUATEX,
+which means that we also have \LUA\ with its garbage collector. Add \CONTEXT\ to
+that, which is not that small and preloads quite some resources, and it will be
+clear that these devices actually perform quite well, given slower memory, slower
+disks, small caches etc. With down|-|scaled intel chips showing up it can only
+get better. Keep in mind that we only need one core, so the speed of one core
+matters more than having multiple cores available, although the other cores can
+be wasted on keeping up with your social demands on such a device in parallel
+with the \TEX\ run.
+
+A runtime five to ten times slower than a decent laptop is not something that we
+look forward to in a production environment, but when you're on the road it is
+quite okay, especially if it can replace a somewhat heavy portable workstation
+like we do. Okay, how much \TEX\ processing do you need when mobile, but still.
+As vendors of server hardware are looking into high density servers with lots of
+small fast processors, we might at some point actually use \TEX\ on such
+hardware. By then performance might be en par with virtual machines running on
+average loaded machines.
+
+We are pretty sure that on following \CONTEXT\ meetings more such experiments
+will be done so we'll keep you posted.

+\startsection[title=Introduction]
+
+When you use \TEX, join the community, follow mailing lists, read manuals,
+and|/|or attend meetings, there will come a moment when you run into the word
+\quote {node}. But, as a regular user, even if you write macros, you can happily
+ignore them because in practice you will never really see them. They are hidden
+deep down in \TEX.
+
+Some expert \TEX ies love to talk about \TEX's mouth, stomach, gut and other
+presumed bodily elements. Maybe it is seen as proof of the deeper understanding
+of this program as Don Knuth uses these analogies in his books about \TEX\ when
+he discusses how \TEX\ reads the input, translates it and digests it into a
+something that can be printed or viewed. No matter how your input gets digested,
+at some point we get nodes. However, as users have no real access to the
+internals, nodes never show themselves to the user. They have no bodily analogy
+either.
+
+A character that is read from the input can become a character node. Multiple
+characters can become a linked list of nodes. Such a list can contain other kind
+of nodes as well, for instance spaced become glue. There can also be penalties
+that steer the machinery. And kerns too: fixed displacements. Such a list can be
+wrapped in a box. In the process hyphenation is applied, characters become glyphs
+and intermediate math nodes becomes a combination of regular glyphs, kerns and
+glue, wrapped into boxes. So, an hbox that contains the three glyphs \type {tex}
+can be represented as follows:

+      \stopFLOWcell
+      \startFLOWcell
+        \name       {e}
+        \location   {3,1}
+        \shape      {action}
+        \text       {e}
+        \connection [+t-t] {x}
+        \connection [-b+b] {t}
+      \stopFLOWcell
+      \startFLOWcell
+        \name       {x}
+        \location   {4,1}
+        \shape      {action}
+        \text       {x}
+        \connection [-b+b] {e}
+      \stopFLOWcell
+    \stopFLOWchart
+    \FLOWchart[nodes]
+\stoplinecorrection
+
+Eventually a long sequence of nodes can become a paragraph of lines and each line
+is a box. The lines together make a page which is also a box. There are many kind
+of nodes but some are rather special and don't translate directly to some visible
+result. When dealing with \TEX\ as user we can forget about nodes: we never really
+see them.
+
+In this example we see an hlist (hbox) node. Such a node has properties like
+width, height, depth, shift etc. The characters become glyph nodes that have
+(among other properties) a reference to a font, character, language.
+
+Because \TEX\ is also about math, and because math is somewhat special, we have
+noads, some intermediate kind of node that makes up a math list, that eventually
+gets transformed into a list of nodes. And, as proof of extensibility, Knuth came
+up with a special node that is more or less ignored by the machinery but travels
+with the list and can be dealt with in special backend code. Their name indicates
+what it's about: they are called whatsits (which sounds better that whatevers).
+In \LUATEX\ some whatsits are used in the frontend, for instance directional
+information is stored in whatsits.
+
+The \LUATEX\ engine not only opens up the \UNICODE\ and \OPENTYPE\ universes, but
+also the traditional \TEX\ engine. It gives us access to nodes. And this permits
+us to go beyond what was possible before and therefore on mailing lists like the
+\CONTEXT\ list, the word node will pop up more frequently. If you look into the
+\LUA\ files that ship with \CONTEXT\ you cannot avoid seeing them. And, when you
+use the \CLD\ interface you might even want to manipulate them. A nice side
+effect is that you can sound like an expert without having to refer to bodily
+aspects of \TEX: you just see them as some kind of \LUA\ userdata variable. And
+you access them like tables: they are abstracts units with properties.
+
+\stopsection
+
+\startsection[title=Basics]
+
+Nodes are kind of special in the sense that you need to keep an eye on creation
+and destruction. In \TEX\ itself this is mostly hidden:
+
+\startbuffer
+\setbox0\hbox{some text}
+\stopbuffer
+
+\typebuffer
+
+If we look {\em into} this box we get a list of glyphs (see \in {figure}
+[fig:dummy:1]).
+
+\startplacefigure[reference=fig:dummy:1]
+    \getbuffer
+    \boxtoFLOWchart[dummy]{0}
+    \small
+    \FLOWchart[dummy][width=14em,height=3em,dx=1em,dy=.75em] % ,hcompact=yes]
+\stopplacefigure
+
+In \TEX\ you can flush such a box using \type {\box0} or copy it using \type
+{\copy0}. You can also flush the contents i.e.\ omit the wrapper using \type
+{\unhbox0} and \type {\unhcopy0}. The possibilities for disassembling the
+content of a box (or any list for that matter) are limited. In practice you
+can consider disassembling to be absent.
+
+This is different at the \LUA\ end: there we can really start at the beginning of
+a list, loop over it and see what's in there as well as change, add and remove
+nodes. The magic starts with:
+
+\starttyping
+local box = tex.box[0]
+\stoptyping
+
+Now we have a variable that has a so called \type {hlist} node. This node has not
+only properties like \type {width}, \type {height}, \type {depth} and \type
+{shift}, but also a pointer to the content: \type {list}.
+
+\starttyping
+local list = box.list
+\stoptyping
+
+Now, when we start messing with this list, we need to keep into account that the
+nodes are in fact userdata objects, that is: they are efficient \TEX\ data
+structures that have a \LUA\ interface. At the \TEX\ end the repertoire of
+commands that we can use to flush boxes is rather limited and as we cannot mess
+with the content we have no memory management issues. However, at the \LUA\ end
+this is different. Nodes can have pointers to other nodes and they can even have
+special properties that relate to other resources in the program.
+
+Take this example:
+
+\starttyping
+\setbox0\hbox{some text}
+\directlua{node.write(tex.box[0])}
+\stoptyping
+
+At the \TEX\ end we wrap something in a box. Then we can at the \LUA\ end access
+that box and print it back into the input. However, as \TEX\ is no longer in
+control it cannot know that we already flushed the list. Keep in mind that this
+is a simple example, but imagine more complex content, that contains hyperlinks
+or so. Now take this:
+
+\starttyping
+\setbox0\hbox{some text 1}
+\setbox0\hbox{some text 2}
+\stoptyping
+
+Here \TEX\ knows that the box has content and it will free the memory beforehand
+and forget the first text. Or this:
+
+\starttyping
+\setbox0\hbox{some text}
+\box0 \box0
+\stoptyping
+
+The box will be used and after that it's empty so the second flush is basically a
+harmless null operation: nothing gets inserted. But this:
+
+\starttyping
+\setbox0\hbox{some text}
+\directlua{node.write(tex.box[0])}
+\directlua{node.write(tex.box[0])}
+\stoptyping
+
+will definitely fail. The first call flushes the box and the second one sees
+no box content and will bark. The best solution is to use a copy:
+
+\starttyping
+\setbox0\hbox{some text}
+\directlua{node.write(node.copy_list(tex.box[0]))}
+\stoptyping
+
+That way \TEX\ doesn't see a change in the box and will free it when needed: when
+it gets flushed, reassigned, at the end of a group, wherever.
+
+In \CONTEXT\ a somewhat shorter way of printing back to \TEX\ is the following
+and we will use that:
+
+\starttyping
+\setbox0\hbox{some text}
+\ctxlua{context(node.copy_list(tex.box[0])}
+\stoptyping
+
+or shortcut into \CONTEXT:
+
+\starttyping
+\setbox0\hbox{some text}
+\cldcontext{node.copy_list(tex.box[0])}
+\stoptyping
+
+As we've now arrived at the \LUA\ end, we have more possibilities with nodes. In
+the next sections we will explore some of these.
+
+\stopsection
+
+\startsection[title=Management]
+
+The most important thing to keep in mind is that each node is unique in the sense
+that it can be used only once. If you don't need it and don't flush it, you
+should free it. If you need it more than once, you need to make a copy. But let's
+first start with creating a node.
+
+\starttyping
+local g = node.new("glyph")
+\stoptyping
+
+This node has some properties that need to be set. The most important are the font
+and the character. You can find more in the \LUATEX\ manual.
+
+\starttyping
+g.font = font.current()
+g.char = utf.byte("a")
+\stoptyping
+
+After this we can write it to the \TEX\ input:
+
+\starttyping
+context(g)
+\stoptyping
+
+This node is automatically freed afterwards. As we're talking \LUA\ you can use
+all kind of commands that are defined in \CONTEXT. Take fonts:
+
+\startbuffer
+\startluacode
+local g1 = node.new("glyph")
+local g2 = node.new("glyph")
+
+g1.font = fonts.definers.internal {
+    name = "dejavuserif",
+    size = "60pt",
+}
+
+g2.font = fonts.definers.internal {
+    name = "dejavusansmono",
+    size = "60pt",
+}
+
+g1.char = utf.byte("a")
+g2.char = utf.byte("a")
+
+context(g1)
+context(g2)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We get: \getbuffer, but there is one pitfall: the nodes have to be flushed in
+horizontal mode, so either put \type {\dontleavehmode} in front or add \type
+{context.dontleavehmode()}. If you get error messages like \typ {this can't
+happen} you probably forgot to enter horizontal mode.
+
+In \CONTEXT\ you have some helpers, for instance:
+
+\starttyping
+\startluacode
+local id = fonts.definers.internal { name = "dejavuserif" }
+
+context(nodes.pool.glyph(id,utf.byte("a")))
+context(nodes.pool.glyph(id,utf.byte("b")))
+context(nodes.pool.glyph(id,utf.byte("c")))
+\stopluacode
+\stoptyping
+
+or, when we need these functions a lot and want to save some typing:
+
+\startbuffer
+\startluacode
+local getfont  = fonts.definers.internal
+local newglyph = nodes.pool.glyph
+local utfbyte  = utf.byte
+
+local id = getfont { name = "dejavuserif" }
+
+context(newglyph(id,utfbyte("a")))
+context(newglyph(id,utfbyte("b")))
+context(newglyph(id,utfbyte("c")))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This renders as: \getbuffer. We can make copies of nodes too:
+
+\startbuffer
+\startluacode
+local id = fonts.definers.internal { name = "dejavuserif" }
+local a  = nodes.pool.glyph(id,utf.byte("a"))
+
+for i=1,10 do
+    context(node.copy(a))
+end
+
+node.free(a)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This gives: \getbuffer. Watch how afterwards we free the node. If we have not one
+node but a list (for instance because we use box content) you need to use the
+alternatives \type {node.copy_list} and \type {node.free_list} instead.
+
+In \CONTEXT\ there is a convenient helper to create a list of text nodes:
+
+\startbuffer
+\startluacode
+context(nodes.typesetters.tonodes("this works okay"))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+And indeed, \getbuffer, even when we use spaces. Of course it makes
+more sense (and it is also more efficient) to do this:
+
+\startbuffer
+\startluacode
+context("this works okay")
+\stopluacode
+\stopbuffer
+
+In this case the list is constructed at the \TEX\ end. We have now learned enough
+to start using some convenient operations, so these are introduced next. Instead
+of the longer \type {tonodes} call we will use the shorter one:
+
+\starttyping
+local head, tail = string.tonodes("this also works"))
+\stoptyping
+
+As you see, this constructor returns the head as well as the tail of the
+constructed list.
+
+\stopsection
+
+\startsection[title=Operations]
+
+If you are familiar with \LUA\ you will recognize this kind of code:
+
+\starttyping
+local str = "time: " .. os.time()
+\stoptyping
+
+Here a string \type {str} is created that is built out if two concatinated
+snippets. And, \LUA\ is clever enough to see that it has to convert the number to
+a string.
+
+In \CONTEXT\ we can do the same with nodes:
+
+\startbuffer
+\startluacode
+local foo = string.tonodes("foo")
+local bar = string.tonodes("bar")
+local amp = string.tonodes(" & ")
+
+context(foo .. amp .. bar)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This will append the two node lists: \getbuffer.
+
+\startbuffer
+\startluacode
+local l = string.tonodes("l")
+local m = string.tonodes(" ")
+local r = string.tonodes("r")
+
+context(5 * l .. m .. r * 5)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+You can have the multiplier on either side of the node: \getbuffer.
+Addition and subtraction is also supported but it comes in flavors:
+
+\startbuffer
+\startluacode
+local l1 = string.tonodes("aaaaaa")
+local r1 = string.tonodes("bbbbbb")
+local l2 = string.tonodes("cccccc")
+local r2 = string.tonodes("dddddd")
+local m  = string.tonodes(" + ")
+
+context((l1 - r1) .. m .. (l2 + r2))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+In this case, as we have two node (lists) involved in the addition and
+subtraction, we get one of them injected into the other: after the first, or
+before the last node. This might sound weird but it happens.
+
+\dontleavehmode \start \maincolor \getbuffer \stop
+
+We can use these operators to take a slice of the given node list.
+
+\startbuffer
+\startluacode
+local l = string.tonodes("123456")
+local r = string.tonodes("123456")
+local m = string.tonodes("+ & +")
+
+context((l - 3) .. (1 + m - 1).. (3 + r))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+So we get snippets that get appended: \getbuffer. The unary operator
+reverses the list:
+
+\startbuffer
+\startluacode
+local l = string.tonodes("123456")
+local r = string.tonodes("123456")
+local m = string.tonodes(" & ")
+
+context(l .. m .. - r)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This is probably not that useful, but it works as expected: \getbuffer.
+
+We saw that \type {*} makes copies but sometimes that is not enough. Consider the
+following:
+
+\startbuffer
+\startluacode
+local n = string.tonodes("123456")
+
+context((n - 2) .. (2 + n))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Because the slicer frees the unused nodes, the value of \type {n} in the second
+case is undefined. It still points to a node but that one already has been freed.
+So you get an error message. But of course (as already demonstrated) this is
+valid:
+
+\startbuffer
+\startluacode
+local n = string.tonodes("123456")
+
+context(2 + n - 2)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We get the two middle characters: \getbuffer. So, how can we use a
+node (list) several times in an expression? Here is an example
+
+\startbuffer
+\startluacode
+local l = string.tonodes("123")
+local m = string.tonodes(" & ")
+local r = string.tonodes("456")
+
+context((l^1 .. r^1)^2 .. m^1 .. r .. m .. l)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Using \type {^} we create copies, so we can still use the original later on. You
+can best make sure that one reference to a node is not copied because otherwise
+we get a memory leak. When you write the above without copying \LUATEX\ most
+likely end up in a loop. The result of the above is:
+
+\blank \start \dontleavehmode \maincolor \getbuffer \stop \blank
+
+Let's repeat it once more time: keep in mind that we need to do the memory
+management ourselves. In practice we will seldom need more than the
+concatination, but if you make complex expressions be prepared to loose some
+memory when you copy and don't free them. As \TEX\ runs are normally limited in
+time this is hardly an issue.
+
+So what about the division. We needed some kind of escape and as with \type
+{lpeg} we use the \type {/} to apply additional operations.
+
+\startbuffer
+\startluacode
+local l = string.tonodes("123")
+local m = string.tonodes(" & ")
+local r = string.tonodes("456")
+
+local function action(n)
+    for g in node.traverse_id(node.id("glyph"),n) do
+        g.char = string.byte("!")
+    end
+    return n
+end
+
+context(l .. m / action .. r)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+And indeed we the middle glyph gets replaced: \getbuffer.
+
+\startbuffer
+\startluacode
+local l = string.tonodes("123")
+local r = string.tonodes("456")
+
+context(l .. nil .. r)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+When you construct lists programmatically it can happen that one of the
+components is nil and to some extend this is supported: so the above
+gives: \getbuffer.
+
+Here is a summary of the operators that are currently supported. Keep in mind that
+these are not built in \LUATEX\ but extensions in \MKIV. After all, there are many
+ways to map operators on actions and this is just one.
+
+\starttabulate[|l|l|]
+\NC \type{n1 .. n2} \NC append nodes (lists) \type {n1} and \type {n2}, no copies \NC \NR
+\NC \type{n * 5}    \NC append 4 copies of node (list) \type {n} to \type {n} \NC \NR
+\NC \type{5 + n}    \NC discard the first 5 nodes from list \type {n} \NC \NR
+\NC \type{n - 5}    \NC discard the last 5 nodes from list \type {n} \NC \NR
+\NC \type{n1 + n2}  \NC inject (list) \type {n2} after first of list \type {n1} \NC \NR
+\NC \type{n1 - n2}  \NC inject (list) \type {n2} before last of list \type {n1} \NC \NR
+\NC \type{n^2}      \NC make two copies of node (list) \type {n} and keep the orginal \NC \NR
+\NC \type{- n}      \NC reverse node (list) \type {n} \NC \NR
+\NC \type{n / f}    \NC apply function \type {f} to node (list) \type {n} \NC \NR
+\stoptabulate
+
+As mentioned, you can only use a node or list once, so when you need it more times, you need
+to make copies. For example:
+
+\startbuffer
+\startluacode
+local l = string.tonodes(     -- maybe: nodes.maketext
+    " 1 2 3 "
+)
+local r = nodes.tracers.rule( -- not really a user helper (spec might change)
+    string.todimen("1%"),     -- or maybe: nodes.makerule("1%",...)
+    string.todimen("2ex"),
+    string.todimen(".5ex"),
+    "maincolor"
+)
+
+context(30 * (r^1 .. l) .. r)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This gives a mix of glyphs, glue and rules: \getbuffer. Of course you can wonder
+how often this kind of juggling happens in use cases but at least in some core
+code the concatination (\type {..}) gives a bit more readable code and the
+overhead is quite acceptable.

+\startsection[title=Introduction]
+
+This is not the first story about speed and it will probably not be the last one
+either. This time we discuss a substantial speedup: upto 50\% with \LUAJITTEX.
+So, if you don't want to read further at least know that this speedup came at the
+cost of lots of testing and adapting code. Of course you could be one of those
+users who doesn't care about that and it may also be that your documents don't
+qualify at all.
+
+Often when I see a kid playing a modern computer game, I wonder how it gets done:
+all that high speed rendering, complex environments, shading, lightning,
+inter||player communication, many frames per second, adapted story lines,
+\unknown. Apart from clever programming, quite some of the work gets done by
+multiple cores working together, but above all the graphics and physics
+processors take much of the workload. The market has driven the development of
+this hardware and with success. In this perspective it's not that much of a
+surprise that complex \TEX\ jobs still take some time to get finished: all the
+hard work has to be done by interpreted languages using rather traditional
+hardware. Of course all kind of clever tricks make processors perform better than
+years ago, but still: we don't get much help from specialized hardware. \footnote
+{Apart from proper rendering on screen and printing on paper.} We're sort of
+stuck: when I replaced my 6 year old laptop (when I buy one, I always buy the
+fastest one possible) for a new one (so again a fast one) the gain in speed of
+processing a document was less than twice. The many times faster graphic
+capabilities are not of much help there, not is twice the amount of cores.
+
+So, if we ever want to go much faster, we need to improve the software. The
+reason for trying to speed up \MKIV\ has been mentioned before, but let's
+summarize it here:
+
+\startitemize
+
+\startitem
+    There was a time when users complained about the speed of \CONTEXT,
+    especially compared to other macro packages. I'm not so sure if this is still
+    a valid complaint, but I do my best to avoid bottlenecks and much time goes
+    into testing efficiency.
+\stopitem
+
+\startitem
+    Computers don't get that much faster, at least we don't see an impressive
+    boost each year any more. We might even see a slowdown when battery live
+    dominates: more cores at a lower speed seems to be a trend and that doesn't
+    suit current \TEX\ engines well. Of course we assume that \TEX\ will be
+    around for some time.
+\stopitem
+
+\startitem
+    Especially in automated workflows where multiple products each demanding a
+    couple of runs are produced speed pays back in terms of resources and
+    response time. Of course the time invested in the speedup is never regained
+    by ourselves, but we hope that users appreciate it.
+\stopitem
+
+\startitem
+    The more we do in \LUA, read: the more demanding users get and the more
+    functionality is enabled, the more we need to squeeze out of the processor.
+    And we want to do more in \LUA\ in order to get better typeset results.
+\stopitem
+
+\startitem
+    Although \LUA\ is pretty fast, future versions might be slower. So, the more
+    efficient we are, the less we probably suffer from changes.
+\stopitem
+
+\startitem
+    Using more complex scripts and fonts is so demanding that the number of pages
+    per second drops dramatically. Personally I consider a rate of 15 pps with
+    \LUATEX\ or 20 pps with \LUAJITTEX\ reasonable minima on my laptop. \footnote
+    {A Dell 6700 laptop with Core i7 3840QM, 16 GB memory and SSD, running 64 bit
+    Windows 8.}
+\stopitem
+
+\startitem
+    Among the reasons why \LUAJIT\ jitting does not help us much is that (at
+    least in \CONTEXT) we don't use that many core functions that qualify for
+    jitting. Also, as runs are limited in time and much code kicks in only a few
+    times the analysis and compilation doesn't pay back in runtime. So we cannot
+    simply sit down and wait till matters improve.
+\stopitem
+
+\stopitemize
+
+Luigi Scarso and I have been exploring several options, with \LUATEX\ as well as
+\LUAJITTEX. We observed that the virtual machine in \LUAJITTEX\ is much faster so
+that engine already gives a boots. The advertised jit feature can best be
+disabled as it slows down a run noticeably. We played with \type {ffi} as well,
+but there is additional overhead involved (\type {cdata}) as well as limited
+support for userdata, so we can forget about that too. \footnote {As we've now
+introduced getters we can construct a metatable at the \LUA\ end as that is what
+\type {ffi} likes most. But even then, we don't expect much from it: the four
+times slow down that experiments showed will not magically become a large gain.}
+Nevertheless, the twice as fast virtual machine of \LUAJIT\ is a real blessing,
+especially if you take into account that \CONTEXT\ spends quite some time in
+\LUA. We're also looking forward to the announced improved garbage collector of
+\LUAJIT.
+
+In the end we started looking at \LUATEX\ itself. What can be gained there,
+within the constraints of not having to completely redesign existing
+(\CONTEXT) \LUA\ code? \footnote {In the end a substantial change was needed but
+only in accessing node properties. The nice thing about C is that there macros
+often provide a level of abstraction which means that a similar adaption of \TEX\
+source code would be more convenient.}
+
+\stopsection
+
+\startsection[title={Two access models}]
+
+Because the \CONTEXT\ code is reasonably well optimized already, the only option
+is to look into \LUATEX\ itself. We had played with the \TEX||\LUA\ interface
+already and came to the conclusion that some runtime could be gained there. On
+the long run it adds up but it's not too impressive; these extensions are
+awaiting integration. Tracing and bechmarking as well as some quick and dirty
+patches demonstrated that there were two bottlenecks in accessing fields in
+nodes: checking (comparing the metatables) and constructing results (userdata
+with metatable).
+
+In case you're infamiliar with the concept this is how nodes work. There is an
+abstract object called node that is in \LUA\ qualified as user data. This object
+contains a pointer to \TEX's node memory. \footnote {The traditional \TEX\ node
+memory manager is used, but at some point we might change to regular C
+(de)allocation. This might be slower but has some advantages too.} As it is real
+user data (not so called light) it also carries a metatable. In the metatble
+methods are defined and one of them is the indexer. So when you say this:
+
+\starttyping
+local nn = n.next
+\stoptyping
+
+given that \type {n} is a node (userdata) the \type {next} key is resolved up
+using the \type {__index} metatable value, in our case a function. So, in fact,
+there is no \type {next} field: it's kind of virtual. The index function that
+gets the relevant data from node memory is a fast operation: after determining
+the kind of node, the requested field is located. The return value can be a
+number, for instance when we ask for \type {width}, which is also fast to return.
+But it can also be a node, as is the case with \type {next}, an then we need to
+allocate a new userdata object (memory management overhead) and a metatable has
+to be associated. And that comes at a cost.
+
+In a previous update we had already optimized the main \type {__index} function
+but felt that some more was possible. For instance we can avoid the lookup of the
+metatable for the returned node(s). And, if we don't use indexed access but a
+instead a function for frequently accessed fields we can sometimes gain a bit too.
+
+A logical next step was to avoid some checking, which is okay given that one pays
+a bit attention to coding. So, we provided a special table with some accessors of
+frequently used fields. We actually implemented this as a so called \quote {fast}
+access model, and adapted part of the \CONTEXT\ code to this, as we wanted to see
+if it made sense. We were able to gain 5 to 10\% which is nice but still not
+impressive. In fact, we concluded that for the average run using fast was indeed
+faster but not enough to justify rewriting code to the (often) less nice looking
+faster access. A nice side effect of the recoding was that I can add more advanced
+profiling.
+
+But, in the process we ran into another possibility: use accessors exclusively
+and avoiding userdata by passing around references to \TEX\ node memory directly.
+As internally nodes can be represented by numbers, we ended up with numbers, but
+future versions might use light userdata instead to carry pointers around. Light
+userdata is cheap basic object with no garbage collection involved. We tagged
+this method \quote {direct} and one can best treat the values that gets passed
+around as abstract entities (in \MKIV\ we call this special view on nodes
+\quote {nuts}).
+
+So let's summarize this in code. Say that we want to know the next node of
+\type {n}:
+
+\starttyping
+local nn = n.next
+\stoptyping
+
+Here \type {__index} will be resolved and the associated function be called. We
+can avoid that lookup by applying the \type {__index} method directly (after all,
+that one assumes a userdata node):
+
+\starttyping
+local getfield = getmetatable(n).__index
+
+local nn = getfield(n,"next") -- userdata
+\stoptyping
+
+But this is not a recomended interface for regular users. A normal helper that
+does checking is as about fast as the indexed method:
+
+\starttyping
+local getfield = node.getfield
+
+local nn = getfield(n,"next") -- userdata
+\stoptyping
+
+So, we can use indexes as well as getters mixed and both perform more of less
+equal. A dedicated getter is somewhat more efficient:
+
+\starttyping
+local getnext = node.getnext
+
+local nn = getnext(n) -- userdata
+\stoptyping
+
+If we forget about checking, we can go fast, in fact the nicely interfaced \type
+{__index} is the fast one.
+
+\starttyping
+local getfield = node.fast.getfield
+
+local nn = getfield(n,"next") -- userdata
+\stoptyping
+
+Even more efficient is the following as that one knows already what to fetch:
+
+\starttyping
+local getnext = node.fast.getnext
+
+local nn = getnext(n) -- userdata
+\stoptyping
+
+The next step, away from userdata was:
+
+\starttyping
+local getfield = node.direct.getfield
+
+local nn = getfield(n,"next") -- abstraction
+\stoptyping
+
+and:
+
+\starttyping
+local getnext = node.direct.getnext
+
+local nn = getnext(n) -- abstraction
+\stoptyping
+
+Because we considered three variants a bit too much and because \type {fast} was
+only 5 to 10\% faster in extreme cases, we decided to drop that experimental code
+and stick to providing accessors in the node namespace as well as direct variants
+for critical cases.
+
+Before you start thinking: \quote {should I rewrite all my code?} think twice!
+First of all, \type {n.next} is quite fast and switching between the normal and
+direct model also has some cost. So, unless you also adapt all your personal
+helper code or provide two variants of each, it only makes sense to use direct
+mode in critical situations. Userdata mode is much more convenient when
+developing code and only when you have millions of access you can gain by direct
+mode. And even then, if the time spent in \LUA\ is small compared to the time
+spent in \TEX\ it might not even be noticeable. The main reason we made direct
+variants is that it does pay of in \OPENTYPE\ font processing where complex
+scripts can result in many millions of calls indeed. And that code will be set up
+in such a way that it will use userdata by default and only in well controlled
+case (like \MKIV) we will use direct mode. \footnote {When we are confident
+that \type {direct} node code is stable we can consider going direct in generic
+code as well, although we need to make sure that third party code keeps working.}
+
+Another thing to keep in mind is that when you provide hooks for users you should
+assume that they use the regular mode so you need to cast the plugins onto direct
+mode then. Because the idea is that one should be able to swap normal functions
+by direct ones (which of course is only possible when no indexes are used) all
+relevant function in the \type {node} namespace are available in \type {direct}
+as well. This means that the following code is rather neutral:
+
+\starttyping
+local x = node -- or: x = node.direct
+
+for n in x.traverse(head) do
+  if x.getid(n) == node.id("glyph") and x.getchar(n) == 0x123 then
+    x.setfield(n,"char",0x456)
+  end
+end
+\stoptyping
+
+Of course one needs to make sure that \type {head} fits the model. For this you
+can use the cast functions:
+
+\starttyping
+node.direct.todirect(node or direct)
+node.direct.tonode(direct or node)
+\stoptyping
+
+These helpers are flexible enough to deal with either model. Aliasing the
+functions to locals is of course more efficient when a large number of calls
+happens (when you use \LUAJITTEX\ it will do some of that for you automatically).
+Of course, normally we use a more natural variant, using an id traverser:
+
+\starttyping
+for n in node.traverse_id(head,node.id("glyph")) do
+  if n.char == 0x123 then
+    n.char = 0x456
+  end
+end
+\stoptyping
+
+This is not that much slower, especially when it's only ran once. Just count the
+number of characters on a page (or in your document) and you will see that it's
+hard to come up with that many calls. Of course, processing many pages of Arabic
+using a mature font with many features enabled and contextual lookups, you do run
+into quantities. Tens of features times tens of contextual lookup passes can add
+up considerably. In Latin scripts you never reach such numbers, unless you use
+fonts like Zapfino.
+
+\stopsection
+
+\startsection[title={The transition}]
+
+After weeks of testing, rewriting, skyping, compiling and making decisions, we
+reached a more or less stable situation. At that point we were faced with a
+speedup that gave us a good feeling, but transition to the faster variant has a
+few consequences.
+
+\startitemize
+
+\startitem We need to use an adapted code base: indexes are to be replaced by
+function calls. This is a tedious job that can endanger stability so it has to be
+done with care. \footnote {The reverse is easier, as converting getters and
+setters to indexed is a rather simple conversion, while for instance changing
+type {.next} into a \type {getnext} needs more checking because that key is not
+unique to nodes.} \stopitem
+
+\startitem When using an old engine with the new \MKIV\ code, this approach will
+result in a somewhat slower run. Most users will probably accept a temporary
+slowdown of 10\%, so we might take this intermediate step. \stopitem
+
+\startitem When the regular getters and setters become available we get back to
+normal. Keep in mind that these accessors do some checking on arguments so that
+slows down to the level of using indexes. On the other hand, the dedicated ones
+(like \type {getnext}) are more efficient so there we gain. \stopitem
+
+\startitem As soon as direct becomes available we suddenly see a boost in speed.
+In documents of average complexity this is 10-20\% and when we use more complex
+scripts and fonts it can go up to 40\%. Here we assume that the macro package
+spends at least 50\% of its time in \LUA. \stopitem
+
+\stopitemize
+
+If we take the extremes: traditional indexed on the one hand versus optimized
+direct in \LUAJITTEX, a 50\% gain compared to the old methods is feasible.
+Because we also retrofitted some fast code into the regular accessor, indexed
+mode should also be somewhat faster compared to the older engine.
+
+In addition to the already provide helpers in the \type {node} namespace, we
+added the following:
+
+\starttabulate[|Tl|p|]
+\HL
+\NC getnext    \NC this one is used a lot when analyzing and processing node lists \NC \NR
+\NC getprev    \NC this one is used less often but fits in well (companion to \type {getnext}) \NC \NR
+\NC getfield   \NC this is the general accessor, in userdata mode as fast as indexed \NC \NR
+\HL
+\NC getid      \NC one of the most frequent called getters when parsing node lists \NC \NR
+\NC getsubtype \NC especially in fonts handling this getter gets used \NC \NR
+\HL
+\NC getfont    \NC especially in complex font handling this is a favourite \NC \NR
+\NC getchar    \NC as is this one \NC \NR
+\HL
+\NC getlist    \NC we often want to recurse into hlists and vlists and this helps \NC \NR
+\NC getleader  \NC and also often need to check if glue has leader specification (like list) \NC \NR
+\HL
+\NC setfield   \NC we have just one setter as setting is less critical \NC \NR
+\HL
+\stoptabulate
+
+As \type {getfield} and \type {setfield} are just variants on indexed access, you
+can also use them to access attributes. Just pass a number as key. In the \type
+{direct} namespace, helpers like \type {insert_before} also deal with direct
+nodes.
+
+We currently only provide \type {setfield} because setting happens less than
+getting. Of course you can construct nodelists at the \LUA\ end but it doesn't
+add up that fast and indexed access is then probably as efficient. One reason why
+setters are less an issue is that they don't return nodes so no userdata overhead
+is involved. We could (and might) provide \type {setnext} and \type {setprev},
+although, when you construct lists at the \LUA\ end you will probably use the
+type {insert_after} helper anyway.
+
+\stopsection
+
+\startsection[title={Observations}]
+
+So how do these variants perform? As we no longer have \type {fast} in the engine
+that I use for this text, we can only check \type {getfield} where we can simulate
+fast mode with calling the \type{__index} metamethod. In practice the \type
+{getnext} helper will be somewhat faster because no key has to be checked,
+although the \type {getfield} functions have been optimized according to the
+frequencies of accessed keys already.
+
+\starttabulate
+\NC node[*]              \NC 0.516 \NC \NR
+\NC node.fast.getfield   \NC 0.616 \NC \NR
+\NC node.getfield        \NC 0.494 \NC \NR
+\NC node.direct.getfield \NC 0.172 \NC \NR
+\stoptabulate
+
+Here we simulate a dumb 20 times node count of 200 paragraphs \type {tufte.tex}
+with a little bit of overhead for wrapping in functions. \footnote {When
+typesetting Arabic or using complex fonts we quickly get a tenfold.} We encounter
+over three million nodes this way. We average a couple or runs.
+
+\starttyping
+local function check(current)
+  local n = 0
+  while current do
+    n = n + 1
+    current = getfield(current,"next") -- current = current.next
+  end
+  return n
+end
+\stoptyping
+
+What we see here is that indexed access is quite okay given the amount of nodes,
+but that direct is much faster. Of course we will never see that gain in practice
+because much more happens than counting and because we also spend time in \TEX.
+The 300\% speedup will eventually go down to one tenth of that.
+
+Because \CONTEXT\ avoids node list processing when possible the baseline
+performance is not influenced much.
+
+\starttyping
+\starttext \dorecurse{1000}{test\page} \stoptext
+\stoptyping
+
+With \LUATEX\ we get some 575 pages per second and with \LUAJITTEX\ more than 610
+pages per second.

+  {context(io.loaddata(resolvers.findfile("zapf.tex")))}}
+
+\starttext \dorecurse{1000}{\zapf\par} \stoptext
+\stoptyping
+
+For this test \LUATEX\ needs 3.9 seconds and runs at 54 pages per second, while
+\LUAJITTEX\ needs only 2.3 seconds and gives us 93 pages per second.
+
+Just for the record, if we run this:
+
+\starttyping
+\starttext
+\stoptext
+\stoptyping
+
+a \LUATEX\ runs takes 0.229 seconds and a \LUAJITTEX\ run 0.178 seconds. This includes
+initializing fonts. If we run just this:
+
+\starttyping
+\stoptext
+\stoptyping
+
+\LUATEX\ needs 0.199 seconds and \LUAJITTEX\ only 0.082 seconds. So, in the
+meantime, we hardly spend any time on startup. Launching the binary and managing
+the job with \type {mtxrun} calling \type {mtx-context} adds 0.160 seconds
+overhead. Of course this is only true when you have already ran \CONTEXT\ once as
+the operating system normally caches files (in our case format files and fonts).
+This means that by now an edit|-|preview cycle is quite convenient. \footnote {I
+use \SCITE\ with dedicated lexers as editor and currently \type {sumatrapdf} as
+previewer.}
+
+As a more practical test we used the current version of \type {fonts-mkiv} (166
+pages, using all kind of font tricks and tracing), \type {about} (60 pages, quite
+some traced math) and a torture test of Arabic text (61 pages dense text). The
+following measurements are from 2013-07-05 after adapting some 50 files to the
+new model. Keep in mind that the old binary can fake a fast getfield and setfield
+but that the other getters are wrapped functions. The more we have, the slower it
+gets. We used the mingw versions.

+
+The second row shows what happens when we use the adapted \CONTEXT\ code with an
+older binary. We're slower. The last row is what we will have eventually. All
+documents show a nice gain in speed and future extensions to \CONTEXT\ will no
+longer have the same impact as before. This is because what we here see also
+includes \TEX\ activity. The 300\% increase of speed of node access makes node
+processing less influential. On the average we gain 25\% here and as on these
+documents \LUAJITTEX\ gives us some 40\% gain on indexed access, it gives more
+than 50\% on the direct function based variant.
+
+In the fonts manual some 25 million getter accesses happen while the setters
+don't exceed one million. I lost the tracing files but at some point the Arabic
+test showed more than 100 millions accesses. So it's save to conclude that
+setters are sort of neglectable. In the fonts manual the amount of accesses to
+the previous node were less that 5000 while the id and next fields were the clear
+winners and list and leader fields also scored high. Of course it all depends on
+the kind of document and features used, but we think that the current set of
+helpers is quite adequate. And because we decided to provide that for normal
+nodes as well, there is no need to go direct for more simple cases.
+
+Maybe in the future further tracing might show that adding getters for width,
+height, depth and other properties of glyph, glue, kern, penalty, rule, hlist and
+vlist nodes can be of help, but quite probably only in direct mode combined with
+extensive list manipulations. We will definitely explore other getters but only
+after the current set has proven to be useful.
+
+\stopsection
+
+\startsection[title={Nuts}]
+
+So why going nuts and what are nuts? In Dutch \quote {node} sounds a bit like
+\quote {noot} and translates back to \quote {nut}. And as in \CONTEXT\ I needed
+word for these direct nodes they became \quote {nuts}. It also suits this
+project: at some point we're going nuts because we could squeeze more out
+of \LUAJITTEX, so we start looking at other options. And we're sure some folks
+consider us being nuts anyway, because we spend time on speeding up. And adapting
+the \LUATEX\ and \CONTEXT\ \MKIV\ code mid||summer is also kind of nuts.
+
+At the \CONTEXT\ 2013 conference we will present this new magic and about that
+time we've done enough tests to see if it works our well. The \LUATEX\ engine
+will provide the new helpers but they will stay experimental for a while as one
+never knows where we messed up.
+
+I end with another measurement set. Every now and and then I play with a \LUA\
+variant of the \TEX\ par builder. At some point it will show up on \MKIV\ but
+first I want to abstract it a bit more and provide some hooks. In order to test
+the performance I use the following tests:

+
+We use a \type {\hbox} to determine the baseline performance. Then we break lines
+using the built|-|in parbuilder. Next we do the same but now with the \LUA\

+less because it implements this more efficient.}

+We see that on this test nuts have an advantage over nodes. In this case we

+{flushed} indicates how much extra time would have been involved in that. These
+numbers demonstrate that with nuts the \LUA\ parbuilder is performing 10\% better
+so we gain some. In a regular document only part of the processing involves
+paragraph building so switching to a \LUA\ variant has no big impact anyway,
+unless we have simple documents (like novels). When we bring hz into the picture
+performance will drop (and users occasionally report this) but here we already
+found out that this is mostly an implementation issue: the \LUA\ variant suffers
+less so we will backport some of the improvements. \footnote {There are still
+some aspects that can be approved. For instance these tests still checks lists
+for \type {prev} fields, something that is not needed in future versions.}

+\stopsection

+\startsection[title={\LUA\ 5.3}]
+
+When we were working on this the first working version of \LUA\ 5.3 was
+announced. Apart from some minor changes that won't affect us, the most important
+change is the introduction of integers deep down. On the one hand we can benefit
+from this, given that we adapt the \TEX|-|\LUA\ interfaces a bit: the distinction
+between \type {to_number} and \type {to_integer} for instance. And, numbers are
+always somewhat special in \TEX\ as it relates to reproduction on different
+architectures, also over time. There are some changes in conversion to string
+(needs attention) and maybe at some time also in the automated casting from
+strings to numbers (the last is no big deal for us).
+
+On the one hand the integers might have a positive influence on performance
+especially as scaled points are integers and because fonts use them too (maybe
+there is some advantage in memory usage). But we also need a proper efficient
+round function (or operator) then. I'm wondering if mixed integer and float usage
+will be efficient, but on the the other hand we do not that many calculations so
+the benefits might outperform the drawbacks.
+
+We noticed that 5.2 was somewhat faster but that the experimental generational
+garbage collecter makes runs slower. Let's hope that the garbage collector
+performance doesn't degrade. But the relative gain of node versus direct will
+probably stay.
+
+Because we already have an experimental setup we will probably experiment a bit
+with this in the future. Of course the question then is how \LUAJITTEX\ will work
+out, because it is already not 5.2 compatible it has to be seen if it will
+support the next level. At least in \CONTEXT\ \MKIV\ we can prepare ourselves as
+we did with \LUA\ 5.2 so that we're ready when we follow up.

+\startsection[title=Introduction]
+
+Attributes are a nice extension to \TEX\ as they permits us to let information
+travel with nodes. Internally they are represented as a linked list that
+travels with a node. Because often a sequence of nodes has the same attributes,
+this mechanism is quite efficient. Access is relatively fast too. Attributes
+have a number and a value (also a number) which is fine. Of course one could
+wish for them to be anything, but imagine the amount of management needed
+in the engine if that were the case. Not only does saving and restoring (due to
+grouping) at the \TEX\ end has no \LUA\ equivalent, an overload of the \LUA\
+registry (the most natural interface for this) is not what we want. Of course
+it is also not acceptable that (future) extensions slow down a run. In fact,
+leaner and meaner should be the main objective.
+
+At some point I thought that packing crucial information in a node using a bitset
+would help to speed up some critical mechanisms (mostly fonts) but although
+managing some 32 or 64 on||off states is possible in a more closed macro package,
+in practice it would lead to conflicts in use. Also, an experimental
+implementation of this idea was not faster than using attributes due to the fact
+that manipulating bits also involves function calls that deal with setting,
+resetting, masking and more. It also makes nodes larger and increases the memory
+footprint.
+
+So, when I discarded that idea, I moved to another one, which is associating a
+\LUA\ table with each node (that makes sense). Again, an implementation where
+some way a reference to a table is carried with a node, is non||trivial because
+it has to go via the \LUA\ registry and will not be too efficient in terms of
+speed. Also, when dealing with such information one wants to stay at the \LUA\
+end and not cross the C||boundary too often.
+
+Therefore a different approach was taken which involves a \LUA\ table. The main
+issue with carrying information with a node is not to associate that information,
+but to make sure that it gets cleaned up when a node is freed and copied when a
+node is copied. All nodes that have attributes, also get properties.
+
+\stopsection
+
+\startsection[title=The implementation]
+
+The implementation is rather minimalistic. This is because hard codes solutions
+don't fit in the \LUATEX\ design philosophy. Also, there are many ways to use
+such a mechanism so too much hard coded behaviour only complicates usage.
+
+When a node is copied, we also copy the associated property entry. Normally its
+type is \type {nil} or \type {table}. Depending on how you enabled this
+mechanism, the table copy is shallow (just a reference to the same table), or we
+assign en empty table with the original as metatable index. The second approach
+as some more overhead.
+
+When a new node is assigned, nothing extra is done with the properties. The
+overhead is zero. This means that when you want to assign properties at the \LUA\
+end, you also have to check if a node property already has a table and if not,
+create one. The same is true for querying properties: you have to test if there
+are properties at all.
+
+When you use the \quote {direct} node model, you can directly access the property
+table. But, with direct as well as wrapped nodes, you can also use setters and
+getters. The property table has no metatable so you can add your own one for
+alternative access if needed. In \CONTEXT\ you can best stay away from such hacks
+and use the provided mechanisms because otherwise you get a performance hit.
+
+\stopsection
+
+\startsection[title=The \LUA\ interface]
+
+The interface (in regular nodes as well as direct ones) is quite simple and
+provides five functions:
+
+\starttyping
+set_properties_mode(boolean,boolean)
+flush_properties_table()
+get_properties_table()
+getproperty(node_id)
+setproperty(node_id,value)
+\stoptyping
+
+By default this mechanism is disabled so that when it's not used, there is no
+overhead involved. With \type {set_properties_mode} the first argument determines
+if you enable or disable this mechanism. The properties themselves are untouched.
+When the second argument is \type {true} copied properties create a new table
+with a metatable pointing to the original. You can flush all properties with
+\type {flush_properties_table}.
+
+You can access and set properties with \type {getproperty} and \type
+{setproperty}. Instead you can also use the table approach, where you can reach
+the table with \type {get_properties_table}. Keep in mind that the normal and
+direct calls to this function return a different table.
+
+\stopsection
+
+\startsection[title=A few examples]
+
+The following examples use \CONTEXT\ but apart from the calls to the \type
+{context} namespace, they are rather generic. We have enabled the property
+mechanism with:
+
+\starttyping
+set_properties_mode(true)
+\stoptyping
+
+We fill a box:
+
+\startbuffer
+\newbox\MyPropertyBox
+
+\setbox\MyPropertyBox=\hbox{test}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer[common]
+local list = tex.getbox("MyPropertyBox").list
+
+local function start()
+    context.starttabulate { "||||" }
+    context.HL()
+end
+
+local function stop()
+    context.HL()
+    context.stoptabulate()
+end
+
+local function row(n,p)
+    context.NC() context(tostring(n==p))
+    context.NC() context(tostring(n))
+    context.NC() context(tostring(p))
+    context.NC() context.NR()
+end
+\stopbuffer
+
+\typebuffer[common]
+
+We will demonstrate the four access models. First regular properties
+using functions:
+
+\startbuffer[example]
+for n in node.traverse(list) do
+    node.setproperty(n,{ vif = n })
+end
+start()
+for n in node.traverse(list) do
+    row(n,node.getproperty(n).vif)
+end
+stop()
+\stopbuffer
+
+\typebuffer[example] {\ttxx\ctxluabuffer[common,example]}
+
+We can use a table instead (in fact, we can use both approaches
+mixed:
+
+\startbuffer[example]
+local n_properties = node.get_properties_table()
+
+for n in node.traverse(list) do
+    n_properties[n] = { vit = n }
+    node.direct.setproperty(n,{ vdf = n })
+end
+start()
+for n in node.traverse(list) do
+    row(n,n_properties[n].vit)
+end
+stop()
+\stopbuffer
+
+\typebuffer[example] {\ttxx\ctxluabuffer[common,example]}
+
+The direct method looks the same, apart from a cast to direct:
+
+\startbuffer[example]
+for n in node.direct.traverse(node.direct.todirect(list)) do
+    node.direct.setproperty(n,{ vdf = n })
+end
+start()
+for n in node.direct.traverse(node.direct.todirect(list)) do
+    row(n,node.direct.getproperty(n).vdf)
+end
+stop()
+\stopbuffer
+
+\typebuffer[example] {\tt\ctxluabuffer[common,example]}
+
+Again, we can use the table approach:
+
+\startbuffer[example]
+local d_properties = node.direct.get_properties_table()
+
+for n in node.direct.traverse(node.direct.todirect(list)) do
+    d_properties[n] = { vdt = n }
+end
+start()
+for n in node.direct.traverse(node.direct.todirect(list)) do
+    row(n,d_properties[n].vdt)
+end
+stop()

+
+\startsection[title=Introduction]
+
+In the \quote {mk} and \type {hybrid} progress reports I have spend some words
+on speed. Why is speed this important?
+
+In the early days of \CONTEXT\ I often had to process documents with thousands of
+pages and hundreds of thousands of hyperlinks. You can imagine that this took a
+while, especially when all kind of ornaments had to be added to the page:
+backgrounds, buttons with their own backgrounds and offsets, hyperlink colors
+dependent on their state, etc. Given that multiple runs were needed, this could
+mean that you'd leave the machine running all night in order to get the final
+document.
+
+It was the time when computers got twice the speed with each iteration of
+hardware, so I suppose that it would run substantially faster on my current
+laptop, an old Dell M90 workhorse. Of course a recently added SSD drive adds a
+boost as well. But still, processing such documents on a machine with a 8Mhz 286
+processor and 640 megabytes of memory was close to impossible. But, when I
+compare the speed of core duo M90 with for instance an M4600 with a i5 \CPU\
+running the same clock speed as the M90, I see a factor 2 improvement at most. Of
+course going for a extremely clocked desktop will be much faster, but we're no
+longer seeing a tenfold speedup every few years. On the contrary: we see a shift
+multiple cores, often running at a lower clock speed, with the assumption that
+threaded applications are used. This scales perfectly for web services and
+graphic manipulations but not so much for \TEX. If we want go faster, we need to
+see where we can be more efficient within more or less frozen clock speeds.
+
+Of course there are some developments that help us. First of all, for programs
+like \TEX\ clever caching of files by the operating system helps a lot. Memory
+still becomes faster and \CPU\ cached become larger too. For large documents with
+lots of resources an SSD works out great. As \LUA\ uses floating point, speedup
+in that area also help with \LUATEX. We use virtual machines for \TEX\ related
+services and for some reason that works out quite well, as the underlying
+operating system does lots of housekeeping in parallel. But, with all maxing out,
+we finally end up at the software itself, and in \TEX\ this boils down to a core
+of compiled code along with lots of macro expansions and interpret \LUA\ code.
+
+In the end, the question remains what causes excessive runtimes. Is it the nature
+of the \TEX\ expansion engine? Is it bad macro writing? Is there too much
+overhead? If you notice how fast processing the \TEX\ book goes on modern
+hardware it is clear that the core engine is not the problem. It's no big deal to
+get 100 pages per second on documents that use relative a simple page builder and
+have macros that lack a flexible user interface.
+
+Take the following example:
+
+\starttyping
+\starttext
+\dorecurse{1000}{test\page}
+\stoptext
+\stoptyping
+
+We do nothing special here. We use the default Latin Modern fonts and process
+single words. No burden is put on the pagebuilder either. This way we get on a
+2.33 Ghz T7600 \CPU\ a performance of 185 pages per second. \footnote {In this
+case the mingw version was used. A version using the native \WINDOWS\ compiler
+runs somewhat faster, although this depends on the compiler options. \footnote
+{We've noticed that sometimes the mingw binaries are faster than native binaries,
+but sometimes they're slower.} With \LUAJITTEX\ the 185 pages per second become
+becomes 195 on a 1000 page document.} The estimated \LUA\ overhead in this 1000
+page document is some 1.5 to 2 seconds. The following table shows the performance
+on such a test document with different page numbers in pps (reported pages per
+second).

+
+The startup time, measured on a zero page document, is 0.5 seconds. This includes
+loading the format, loading the embedded \LUA\ scripts and initializing them,
+initializing and loading the file database, locating and loading some runtime
+files and loading the absolute minumum number of fonts: a regular and math Latin
+Modern. A few years before this writing that was more than a second, and the gain
+is due to a slightly faster \LUA\ interpreter as well as improvements in
+\CONTEXT.
+
+So why does this matter at all, if on a larger document the startup time can be
+neglected? It does because when I have to implement a style for a project or are
+developing some functionality a fast edit||run||preview cycle is a must, if only
+because even a few second wait feels uncomfortable. On the other hand, when I
+process a manual of say 150 pages, which uses some tricks to explain matters, I
+don't care if the processing rate is between 5 and 15 pages per second, simply
+because you get (done) what you asked for. It mostly has to do with feeling
+comfortable.
+
+There is one thing to keep in mind: such measurements can vary over time, as they
+depend on several factors. Even in the trivial case we need to:
+
+\startitemize[packed]
+\startitem
+    load macros and \LUA\ code
+\stopitem
+\startitem
+    load additional files
+\stopitem

+\stopitem
+\startitem
+    package the pages, which includes reverting to global document states
+\stopitem
+\startitem
+    create the final output stream (\PDF)
+\stopitem
+\stopitemize
+
+The simple one word per page test is not that slow, and normally for 1000 pages we
+measure around 200 pps. However, due to some small speedups (that somehow add up)
+in three months time I could gain a lot:

+
+Among the improvements in April were a faster output to the console (first
+prototyped in \LUA, later done in the \LUATEX\ engine itself), and a couple of
+low level \LUA\ optimizations. In May a dirty (maybe too tricky) global document
+state restore trick has beeing introduced. Although these changes give nice speed
+bump, they will mostly go unnoticed in more realistic documents. There we are
+happy if we end up in the 20 pps range. So, in practice a more than 10 percent
+speedup between Januari and April is just a dream. \footnote {If you wonder why I
+still bother with such things: sometimes speedups are just a side effect of
+trying to accomplish something else, like less verbose output in full tracing
+mode.}
+
+There are many cases where it does matter to squeeze out every second possible.
+We run workflows where some six documents are generated from one source. If we
+forget about the initial overhead of fetching the source from a remote server
+\footnote {In the user interface we report the time it takes to fetch the source
+so that the typesetter can't be blamed for delays.} gaining half a second per
+document (if we start frech each needs two runs at least) means that the user
+will see the first result one second faster and have them all in six less than
+before. In that case it makes sense to identify bottlenecks in the more high
+level mechanisms.
+
+And this is why during the development of \CONTEXT\ and the transition from
+\MKII\ to \MKIV\ quite some time has been spent on avoiding bottlenecks. And, at
+this point we can safely conclude that, in spite of more advanced functionality,
+the current version of \MKIV\ runs faster than the \MKII\ versions in most cases,
+especially if you take the additional functionality into account (like \UNICODE\
+input and fonts).
+
+\stopsection
+
+\startsection[title=The \TEX\ engine]
+
+Writing inefficient macros is not that hard. If they are used only a few times,
+for instance in setting up properties it plays no role. But if they're expanded
+many times it may make a difference. Because use and development of \CONTEXT\
+went hand in hand we always made sure that the overhead was kept at a minimum.
+
+\startsubject[title=The parbuilder]
+
+There are a couple of places where document processing in a traditional \TEX\
+engine gets a performance hit. Let's start with the parbuilder. Although the
+paragraph builder is quite fast it can responsible for a decent amount of runtime.
+It is also a fact that the parbuilder of the engines derived from original \TEX\
+are more complex. For instance, \OMEGA\ adds bidirectionality to the picture
+which involves some extra checking as well as more nodes in the list. The \PDFTEX\
+engine provides protrusion and expansions, and as that feature was primarily a
+topic of research it was never optimized.
+
+In \LUATEX\ the parbuilder is a mixture of the \PDFTEX\ and \OMEGA\ builders and
+adapted to the fact that we have split the hyphenation, ligature building,
+kerning and breaking a paragraph into lines. The protrusion and expansion code is
+still there but already for a few years I have alternative code for \LUATEX\ that
+simplifies the implementation and could in principle give a speed boost as well
+but till now we never found time to adapt the engine. Take the following test code:
+
+\ifdefined\tufte \else \let\tufte\relax \fi
+
+\starttyping
+\testfeatureonce{100}{\setbox0\hbox{\tufte \par}} \tufte \par
+\stoptyping
+
+In \MKIV\ we use \LUA\ for doing fonts so when we measure this bit we get the
+used time for typesetting our \type {\tufte} quote without breaking it into
+lines. A normal \LUATEX\ run needs 0.80 seconds and a \LUAJITTEX\ run takes 0.47
+seconds. \footnote {All measurements are on a Dell M90 laptop running Windows 8.
+I keep using this machine because it has a decent high res 4:3 screen. It's the
+same machine Luigi Scarso and I used when experimenting with \LUAJITTEX.}
+
+\starttyping
+\testfeatureonce{100}{\setbox0\vbox{\tufte \par}} \tufte \par
+\stoptyping
+
+In this case \LUATEX\ needs 0.80 seconds and \LUAJITTEX\ needs 0.50 seconds and
+as we break the list into lines, we can deduct that close to zero seconds are
+needed to break 100 samples. This (often used) sample text has the interesting
+property that it has many hyphenation points and always gives multiple hyphenated
+lines. So, the parbuilder, if no protrusion and expansion are used, is real fast!
+
+\starttyping
+\startparbuilder[basic]
+  \testfeatureonce{100}{\setbox0\vbox{\tufte \par}} \tufte \par
+\stopparbuilder
+\stoptyping
+
+Here we kick in our \LUA\ version of the par builder. This takes 1.50 seconds for
+\LUATEX\ and 0.90 seconds for \LUAJITTEX. So, \LUATEX\ needs 0.70 seconds to
+break the quote into lines while \LUAJITTEX\ needs 0.43. If we stick to stock
+\LUATEX, this means that a medium complex paragraph needs 0.007 seconds of \LUA\
+time and this is not that is not a time to be worried about. Of course these
+numbers are not that accurate but the measurements are consistent over multiple
+runs for a specific combination of \LUATEX\ and \MKIV. On a more modern machine
+it's probably also close to zero.
+
+These measurements demonstrate that we should add some nuance to the assumption
+that parbuilding takes time. For this we need to distinguish between traditional
+\TEX\ and \LUATEX. In traditional \TEX\ you build an horizontal box or vertical
+box. In \TEX\ speak these are called horizontal and vertical lists. The main text
+flow is a special case and called the main vertical list, but in this perspective
+you can consider it to be like a vertical box.
+
+Each vertical box is split into lines. These lines are packed into horizontal
+boxes. In traditional \TEX\ constructing a list starts with turning references to
+characters into glyphs and ligatures. Kerns get inserted between characters if
+the font requests that. When a vertical box is split into lines, discretionary
+nodes get inserted (hyphenation) and when font expansion or protrusion is enabled
+extra fonts with expanded dimensions get added.
+
+So, in the case of vertical box, building the paragraph is not really
+distinguished from ligaturing, kerning and hyphenation which means that the
+timing of this process is somewhat fuzzy. Also, because after the lines are
+identified some final packing of lines happens and the result gets added to a
+vertical list.
+
+In \LUATEX\ all these stages are split into hyphenation, ligature building,
+kerning, line breaking and finalizing. When the callbacks are not enabled the
+normal machinery kicks in but still the stages are clearly separated. In the case
+of \CONTEXT\ the font ligaturing and kerning get preceded by so called node mode
+font handling. This means that we have extra steps and there can be even more
+steps before and afterwards. And, hyphenation always happens on the whole list,
+contrary to traditional \TEX\ that interweaves this. Keep in mind that because we
+can box and unbox and in that process add extra text the whole process can get
+repeated several times for the same list. Of course already treated glyphs and
+kerns are normally kept as they are.
+
+So, because in  \LUATEX\ the process of splitting into lines is separated we can
+safely conclude that it is real fast. Definitely compared to al the font related
+steps. So, let's go back to the tests and let's do the following:
+
+\starttyping
+\testfeatureonce{1000}{\setbox0\hbox{\tufte}}
+
+\testfeatureonce{1000}{\setbox0\vbox{\tufte}}
+
+\startparbuilder[basic]
+    \testfeatureonce{1000}{\setbox0\vbox{\tufte}}
+\stopparbuilder
+\stoptyping
+
+We've put the text into a macro so that we don't have interference from reading
+files. The test wrapper does the timing. The following measurements are somewhat
+rough but repetition gives similar results. \footnote {Before and between runs
+we do a garbage collection.}

+In line~1 we see the basline: hyphenation, processing fonts and hpacking takes
+9.74 seconds. In the second line we see that breaking the 1000 paragraphs costs
+some 0.20 seconds and when expansion is enabled an extra 12 seconds is needed.
+This means that expansion takes 150\% more runtime. If we delegate the task to
+\LUA\ we need 7.64 seconds for breaking into lines which can not be neglected
+but is still ok given the fact that we break 1000 paragraphs. But, interesting
+is to see that our alternative expansion routine only adds 1.33 seconds which is
+less than 20\%. It must be said that the built|-|in method is not that efficient
+by design if only because it started out differently as part of research.
+
+When measured three months later, the numbers for regular \LUATEX\ (at that time
+version 0.77) with the latest \CONTEXT\ were: 8.52, 8.72 and 15.40 seconds for
+the normal run, which demonstrates that we should not draw too many conclusions
+from such measurements. It's the overal picture that matters.
+
+As with earlier timings, if we use \LUAJITTEX\ we see that the runtime of \LUA\
+is much lower (due to the virtual machine). Of course we're still 20 times slower
+than the built|-| in method but only 10 times slower when we use expansion. To put
+these numbers in perspective: 5 seconds for 1000 paragraphs.

+
+This results in 295 pages in the default layout and takes 17.8 seconds or 16.6
+pages per second. Expansion is not enabled.

+    \dontcomplain \dorecurse{1000}{\tufte\par}
+\stopparbuilder
+\stoptext
+
+That one takes 24.7 seconds and runs at 11.9 pages per second. This is indeed
+slower but on a bit more modern machine I expect better results. We should also
+realize that with Dejavu being a relative large font a difficult paragraph like
+the tufte example gives overfull boxes which in turn is an indication that quite
+some alternative breaks are tried.
+
+When typeset with Latin Modern we don't get overfull boxes and interesting is
+that the native method needs less time (15.9 seconds or 14.1 pages per second)
+while the \LUA\ variant also runs a bit faster: 23.4 or 9.5 pages per second. The
+number of pages is 223 because this font is smaller by design.
+
+When we disable hyphenation the the Dejavu variant takes 16.5 (instead of 17.8)
+seconds and 23.1 (instead of 24.7) seconds for \LUA, so this process is not that
+demanding.
+
+For typesetting so many paragraphs without anything special it makes no sense to
+bother with using a \LUA\ based parbuilder. I must admit that I never had to typeset
+novels so all my 300 page runs are much longer anyway. Anyway, when at some point
+we introduce alternative parbuilding to \CONTEXT, the speed penalty is probably
+acceptable.
+
+Just to indicate that predictions are fuzzy: when we put a \type {\blank} between
+the paragraphs we end up with 313 pages and the traditional method takes 18.3
+while \LUA\ needs 23.6 seconds. One reason for this is that the whitespace is
+also handled by \LUA\ and in the pagebuilder we do some finalizing, so we
+suddenly get interference of other processes (as well as the garbage collector).
+Again an indication that we should not bother too much about speed. I try to make
+sure that the \LUA\ (as well as \TEX) code is reasonably efficient, so in
+practice it's the document style that is a more important factor than the
+parbuilder, it being the traditional one or the \LUA\ variant.
+
+\stopsubject
+
+\startsubject[title=Copying boxes]
+
+As soon as in \CONTEXT\ you start enhancing the page with headers and footers and
+backgrounds you will see that the pps rate drops. This is partly due to the fact
+that suddenly quite some macro expansion takes place in order to check what needs
+to happen (like font and color switches, offsets, overlays etc). But what has
+more impact is that we might end up with copying boxes and that takes time. Also,
+by wrapping and repackaging boxes, we add additional levels of recursion in
+postprocessing code.
+
+\stopsubject
+
+\startsubject[title=Macro expansion]
+
+Taco and I once calculated that \MKII\ spends some 4\% of the time in accessing
+the hash table. This is a clear indication that quite some macro expansions goes
+on. Due to the fact that when I rewrote \MKII\ into \MKIV\ I no longer had to
+take memory and other limitations into account, the codebase looks quite
+different. There we do have more expansion in the mechanism that deals with
+settings but the body of macros is much smaller and less parameters are passed.
+So, the overall performance is better.
+
+\stopsubject
+
+\startsubject[title=Fonts]
+
+Using a font has several aspects. First you have to define an instance. Then, when
+you use it for the first time, the font gets loaded from storage, initialized and
+is passed to \TEX. All these steps are quite optimized. If we process the following
+file:

+So, six fonts are loaded and because XITS is used we also preload the math bold
+variant. Loading of text fonts is delayed but in order initialize math we need to
+preload the math fonts.
+
+If we don't define a bodyfont, a default set gets loaded: Latin Modern. In that
+case we get:
+
+\starttabulate[||T|]
+\NC \type{loaded fonts}    \NC latinmodern-math.otf \NC \NR
+\NC                        \NC lmroman10-bolditalic.otf lmroman12-bold.otf \NC \NR
+\NC                        \NC lmroman12-italic.otf lmroman12-regular.otf \NC \NR
+\NC \type{fonts load time} \NC 0.265 seconds \NR
+\NC \type{runtime}         \NC 0.874 seconds, 1.144 pages/second \NC \NR
+\stoptabulate
+
+Before we had native \OPENTYPE\ Latin Modern math fonts, it took slightly longer
+because we had to load many small \TYPEONE\ fonts and assemble a virtual math font.
+
+As soon as you start mixing more fonts and/or load additional weights and styles
+you will see these times increase. But if you use an already loaded font with
+a different featureset or scaled differently, the burden is rather low. It is
+safe to say that at this moment loading fonts is not a bottleneck.
+
+Applying fonts can be more demanding. For instance if you typeset Arabic or
+Devanagari the amount of node and font juggling definitely influences the total
+runtime. As the code is rather optimized there is not much we can do about it.
+It's the price that comes with flexibility. As far as I can tell getting the same
+results with \PDFTEX\ (if possible at all) or \XETEX\ is not taking less time. If
+you've split up your document in separate files you will seldom run more than a
+dozen pages which is then still bearable.
+
+If you are for instance typesetting a dictionary like document, it does not make
+sense to do all font switches by switching body fonts. Just defining a couple of
+font instances makes more sense and comes at no cost. Being already quite
+efficient given the complexity you should not expect impressive speedups in this
+area.
+
+\stopsubject
+
+\startsubject[title=Manipulations]
+
+The main manipulation that I have to do is to process \XML\ into something
+readable. Using the built||in parser and mapper already has some advantages
+and if applied in the right way it's also rather efficient. The more you restrict
+your queries, the better.
+
+Text manipulations using \LUA\ are often quite fast and seldom the reason for
+seeing slow processing. You can do lots of things at the \LUA\ end and still have
+all the \CONTEXT\ magic by using the \type {context} namespace and function.
+
+\stopsubject
+
+\startsubject[title=Multipass]
+
+You can try to save 1 second on a 20 second run but that is not that impressive
+if you need to process the document three times in order to get your cross
+references right. Okay you'd save 3 seconds but still to get result you needs
+some 60 seconds (unless you already have run the document before). If you have a
+predictable workflow you might know in advance that you only need two runs in
+case you can enforce that with \type {--runs=2}. Furthermore you can try to
+optimize the style by getting rid of redundant settings and inefficient font
+switches. But no matter what we optimize, unless we have a document with no cross
+references, sectioning and positioning, you often end up with the extra run,
+although \CONTEXT\ tries to minimize the number of needed runs needed.
+
+\stopsubject
+
+\startsubject[title=Trial runs]
+
+Some mechanisms, like extreme tables, need multiple passes and all but the last
+one are tagged as trial runs. Because in many cases only dimensions matter, we
+can disable some time consuming code in such case. For instance, at some point
+Alan Braslau and I found out that the new chemical manual ran real slow, mainly
+due to the tens of thousands of \METAPOST\ graphics. Adding support for trial
+runs to the chemical structure macros gave a fourfold improvement. The manual is
+still a slow|-|runner, but that is simply because it has so many runtime
+generated graphics.
+
+\stopsubject
+
+\stopsection
+
+\startsection[title=The \METAPOST\ library]
+
+When the \METAPOST\ library got included we saw a drastic speedup in processing
+document with lots of graphics. However, when \METAPOST\ got a different number
+system (native, double and decimal) the changed memory model immediately lead to
+a slow down. On one 150 page manual which a graphic on each page I saw the
+\METAPOST\ runtime go up from about half a second upto more than 5 seconds. In
+this case I was able to rewrite some core \METAFUN\ macro to better suit the new
+model, but you might not be so lucky. So more careful coding is needed. Of course
+if you only have a few graphics, you can just ignore the change.
+
+\stopsection
+
+\startsection[title=The \LUA\ interpreter]
+
+Where the \TEX\ part of \LUATEX\ is compiled, the \LUA\ code gets interpreted,
+converted into bytecode, and ran by the virtual machine. \LUA\ is by design quite
+portable, which means that the virtual machine is not optimized for a specific
+target. The \LUAJIT\ interpreter on the other hand is written in assembler and
+available for only some platforms, but the virtual machine is about twice as
+fast. The just||in||time part of \LUAJIT\ is not if much help and even can slow
+down processing.
+
+When we moved from \LUA~5.1 to 5.2 we found out that there was some speedup but
+it's hard to say why. There has been changes in the way strings are dealt with
+(\LUA\ hashes strings) and we use lots of strings, really lots. There has been
+changes in the garbage collection and during a run lots of garbage needs to be
+collected. There are some fundamental changes in so called environments and who
+knows what impact that has.
+
+If you ever tried to measure the performance of \LUA, you probably have noticed
+that it is quite fast. This means that it makes no sense to optimize code that
+gets visited only occasionally. But some of the \CONTEXT\ code gets exercised a
+lot, for instance all code that deals with fonts. We use attributes a lot and
+checking them is for good reason not the fastest code. But given the often
+advanced functionality that it makes possible we're willing to pay the price.
+It's also functionality that you seldom need all at the same time and for
+straightforward text only documents all that code is never executed.
+
+When writing \TEX\ or \LUA\ code I spent a lot of time making it as efficient as
+possible in terms of performance and memory usage. The sole reason for that is
+that we happen to process documents where a lot of functionality is combined, so
+if many small speed||ups accumulate to a noticeable performance gain it's worth
+the effort.
+
+So, where does \LUA\ influence runtime? First of all we use \LUA\ do deal with all
+in- and output as well as locating files in the \TEX\ directory structure. Because
+that code is partly shared with the script manager (\type {mtxrun}) it is optimized
+but some more is possible if needed. It is already not the most easy to read code,
+so I don't want to introduce even more obscurity.
+
+Quite some code deals with loading, preparing and caching fonts. That code is
+mostly optimized for memory usage although speed is also okay. This code is only
+called when a font is loaded for the first time (after an update). After that
+loading is at matter of milliseconds. When a text gets typeset and when fonts are
+processed in so called node mode, depending on the script and|/|or enabled
+features, a substantial amount of time is spent in \LUA. There is still a bit
+complex dealing with inserting kerns but future \LUATEX\ will carry kerning
+in the glyph node so there we can gain some runtime.
+
+If a page has 4000 characters and if font features as well as other manipulations
+demand 10 runs over the text, we have 40.000 checks of nodes and potential
+actions. Each involves an id check, maybe a subtype check, maybe some attribute
+checking and possibly some action. So, if we have 200.000 (or more) function
+calls to the per page \TEX\ end it might add up to a lot. Around the time that we
+went to \LUA~5.2 and played with \LUAJITTEX, the node accessors have been sped
+up. This gave indeed a measurable speedup but not on an average document, only on
+the more extreme documents or features. Because the \MKIV\ \LUA\ code goes from
+experimental to production to final, some improvements are made in the process
+but there is not much to gain there. We just have to wait till computers get
+faster, \CPU\ cache get bigger, branch prediction improves, floating point
+calculations take less time, memory is speedy, and flash storage is the standard.
+
+The \LUA\ code is plugged into the \TEX\ machinery via callbacks. For
+instance each time a box is build several callbacks are triggered, even if it's
+an empty box or just an extra wrapper. Take for instance this:
+
+\starttyping
+\hbox \bgroup
+    \hskip \zeropoint
+    \hbox \bgroup
+        test
+    \egroup
+    \hskip \zeropoint
+\egroup
+\stoptyping
+
+Of course you won't come up with this code as it doesn't do much good but macros
+that you use can definitely produce this. For instance, the zero skip can be a
+left and right margin that happen to be. For 10.000 iterations I measured 0.78
+seconds while the text one takes 0.62 seconds:
+
+\starttyping
+\hbox \bgroup
+    \hbox \bgroup
+        test
+    \egroup
+\egroup
+\stoptyping
+
+Why is this? One reason is that a zero skip results in a node and the more nodes
+we have the more memory (de)allocation takes place and the more nodes in the list
+need to be checked. Of course the relative difference is less when we have more
+text. So how can we improve this? The following variant, at the cost of some
+testing takes just as much time.
+
+\starttyping
+\hbox \bgroup
+    \hbox \bgroup
+        \scratchdimen\zeropoint
+        \ifdim\scratchdimen=\zeropoint\else\hskip\scratchdimen\fi
+        test
+        \ifdim\scratchdimen=\zeropoint\else\hskip\scratchdimen\fi
+    \egroup
+\egroup
+\stoptyping
+
+As does this one, but the longer the text, the slower it gets as one of the two
+copies needs to be skipped.
+
+\starttyping
+\hbox \bgroup
+    \hbox \bgroup
+        \scratchdimen\zeropoint
+        \ifdim\scratchdimen=\zeropoint
+            test%
+        \else
+            \hskip\scratchdimen
+            test%
+            \hskip\scratchdimen
+        \fi
+    \egroup
+\egroup
+\stoptyping
+
+Of course most speedup is gained when we don't package at all, so if we test
+before we package but such an optimization is seldom realistic because much more
+goes on and we cannot check for everything. Also, 10.000 is a lot while 0.10
+seconds is something we can live with. By the way, compare the following
+
+\starttyping
+\hbox \bgroup
+    \hskip\zeropoint
+    test%
+    \hskip\zeropoint
+\egroup
+
+\hbox \bgroup
+    \kern\zeropoint
+    test%
+    \kern\zeropoint
+\egroup
+\stoptyping
+
+The first variant is less efficient that the second one, because a skip
+effectively is a glue node pointing to a specification node while a kern is just
+a simple node with the width stored in it. \footnote {On the \LUATEX\ agenda is
+moving the glue spec into the glue node.} I must admit that I seldom keep in mind
+to use kerns instead of skips when possible if only because one needs to be sure
+to be in the right mode, horizontal or vertical, so additional commands might be
+needed.
+
+\stopsection
+
+\startsection[title=Macros]
+
+Are macros a bottleneck? In practice not really. Of course we have optimized the
+core \CONTEXT\ macros pretty well, but one reason for that is that we have a
+rather extensive set of configuration and definition mechanisms that rely heavily
+on inheritance. Where possible all that code is written in a way that macro
+expansion won't hurt too much. because of this users themselves can be more
+liberal in coding. There is a lot going on deep down and if you turn on tracing
+macros you can get horrified. But, not all shown code paths are entered. During the
+move (and rewrite) from \MKII\ to \MKIV\ quite some bottlenecks that result from
+limitations of machines and memory have been removed and as a result the macro
+expansion part is somewhat faster, which nicely compensates the fact that we
+have a more advanced but slower inheritance subsystem. Readability of code and
+speed are probably nicely balanced by now.
+
+Once a macro is read in, its internal representation is pretty efficient. For
+instance references to macro names are just pointers into a hash table. Of
+course, when a macro is seen in your source, that name has to be looked up, but
+that's a fast action. Using short names in the running text for instance really
+doesn't speed up processing much. Switching font sets on the other hand does, as
+then quite some checking happens and the related macros are pretty extensive.
+However, once a font is loaded references to it a pretty fast. Just keep in mind
+that if you define something inside a group, in most cases it got forgotten. So,
+if you need something more often, just define it at the outer level.
+
+\stopsection
+
+\startsection[title=Optimizing code]
+
+Optimizing only makes sense if used very often and called frequently or when the
+problem to solve is demanding. An example of code that gets done often is page
+building, where we pack together many layout elements. Font switches can also be
+time consuming, if defined wrong. These can happen for instance for formulas,
+marked words, cross references, margin notes, footnotes (often a complete
+bodyfont switch), table cells, etc. Yet another is clever vertical spacing that
+happens between structural elements. All these mechanisms are reasonably
+optimized.
+
+I can safely say that deep down \CONTEXT\ is no that inefficient, given what it
+has to do. But when a style for instance does redundant or unnecessary massive
+font switches you are wasting runtime. I dare to say that instead of trying to
+speed up code (for instance by redefining macros) you can better spend the time
+in making styles efficient. For instance having 10 \type {\blank}'s in a row
+will work out rather well but takes time. If you know that a section head has no
+raised or lowered text and no math, you can consider using \type {\definefont} to
+define the right size (especially if it is a special size) instead of defining
+an extra bodyfont size and switch to that as it includes setting up related sizes
+and math.
+
+It might sound like using \LUA\ for some tasks makes \CONTEXT\ slower, but this
+is not true. Of course it's hard to prove because by now we also have more
+advanced font support, cleaner math mechanisms, additional features especially in
+especially structure related mechanisms, etc. There are also mechanisms that are
+faster, for instance extreme tables (a follow up on natural tables) and mixed
+column modes. Of course on the previously mentioned 300 page simple paragraphs
+with simple Latin text the \PDFTEX\ engine is much faster than \LUATEX, also
+because simple fonts are used. But for many of todays document this engine is no
+longer an options. For instance in our \XML\ processing in multiple languages,
+\LUATEX\ beats \PDFTEX. There is not that much to optimize left, so most speed up
+has to come from faster machines. And this is not much different from the past:
+processing 300 page document on a 4.7Mhz 8086 architecture was not much fun and
+we're not even talking of advanced macros here. Faster machines made more clever
+and user friendly systems possible but at the cost of runtime, to even if
+machines have become many times faster, processing still takes time. On the other
+hand, \CONTEXT\ will not become more complex than it is now, so from now on we
+can benefit from faster \CPU's, memory and storage.

+
+% Hans Hagen, PRAGMA ADE, April 2014
+
+\startsection[title=Introduction]
+
+To some it might look as if not much has been done in \LUATEX\ development but
+this is not true. First of all, the 2013 versions (0.75-0.77) are quite stable
+and can be used for production so there is not much buzz about new things.
+\CONTEXT\ users normally won't even notice changes because most is encapsulated
+in functionality that itself won't change. The binaries on the \type
+{contextgarden.net} are always the latest so an update results in binaries that
+are in sync with the \LUA\ and \TEX\ code. Okay, behaviour might become better
+but that could also be the side effect of better coding. Of course some more
+fundamental changes can result in temporary bugs but those are normally easy to
+solve.
+
+Here I will only mention the most important work done. I'll leave out the
+technical details as they can be found in the manual and in articles that were
+written during development. The version discussed is 0.79.
+
+\stopsection
+
+\startsection[title=Speed]
+
+One of the things we spent a lot of time on is speed. This is of course of more
+importance for a system like \CONTEXT\ that can spend more than half its time in
+\LUA, but eventually we all benefit from it. For the average user it doesn't
+matter much if a run takes a few seconds but in automated workflows these
+accumulate and if a process has to produce 5 documents of 20 pages (each
+demanding a few runs) or a few documents of several hundreds of pages, it might
+make a difference. In the \CRITED\ project we aim for complex documents produced
+from \XML\ at a rate of 20 pages per second, at least for stock \LUATEX.
+\footnote {This might look slow but a lot is happening there. A simple 100 page
+document with one word per page processes at more that 500 pages per second but
+this is hard to match with more realistic documents. When processing data from
+bases using the \CLD\ interface getting 50 pages per seconds is no problem.} In
+an edit|-|preview cycle it feels better if we don't use more than half a second
+for a couple of pages: loading the \TEX\ format, initializing the \LUA\ modules,
+loading fonts, typesetting and producing a proper \PDF\ file. We also want to be
+prepared for the ultra portable computers where multiple cores compensate the
+lower frequency, which harms \TEX\ as sequential processor using one core only.
+
+An important aspect of speedup is that it must not obscure the code. This is why
+the easiest way to achieve it is to use a faster variant of \LUA, and \LUAJIT\
+with its faster virtual machine, is a solution for that. We are aware of the
+fact that processors not necessarily become faster, but that on the other hand
+memory becomes larger. Disk speed also got better with the arrival of
+flash based storage. Because \LUATEX\ should run smoothly on future portable
+devices, the more we can gain now, the better it gets in the future. A decent
+basic performance is possible and we don't have to focus too much on memory and
+disk access and mostly need to keep an eye on basic \CPU\ cycles. Although we
+have some ideas about improving performance, tests demonstrate that \LUATEX\
+is not doing that bad and we don't have to change it's internals. In fact, if we
+do it might as well result in a drastic slowdown!
+
+One interesting performance factor is console output. Because \TEX\ outputs
+immediately with hardly any buffering, it depends a lot on the speed of console
+output. This itself depends on what console is used. \UNIX\ consoles normally
+have some buffering and refresh delay built in. There the speed depends on what
+fonts are used and to what extend the output gets interpreted (escape sequences
+are an example). I've run into cases where a run took seconds more because of a
+bad choice of fonts. On \WINDOWS\ it's more complicated since there the standard
+console (like \TEX) is unbuffered. The good news is that there are several
+alternatives that perform quite well, like console2 and conemu. These
+alternatives buffer output and have refresh delays. But still, on a very high res
+screen, with a large console window logging has impact. Interesting is that when
+I run from the editor (SciTE) output is pretty fast, so normally I never notice
+much of a slowdown. Of course these kind of performance issues can hit you more
+when you work in a remote terminal.
+
+The reason why I mention this is that in order to provide a user feedback about
+issues, there has to be some logging and depending on the kind of use, more or
+less is needed. This means that on the \CONTEXT\ mailing list we sometimes get
+complaints about the amount of logging. It is for this reason that much logging is
+optional and all logging can be disabled as well. Because we go through \LUA\
+we have some control over efficiency too. In the current \LUATEX\ release most
+logging can now be intercepted, including error messages.
+
+Talking of a slowdown, in the \CRITED\ project we have to deal with real large
+indices (tens of thousands of entries) and we found out that in the case of
+interactive variants (register entry to text and back) the use of \LUAJITTEX\
+could bring down a run to a grinding halt. In the end, after much testing we
+figured out that a suboptimal string hashing function was the culprit and we did
+extensive tests with both the \LUAJIT, \LUA\ 5.1 and \LUA\ 5.2 variant. We ended
+up by replacing the \LUAJIT\ hash function by the the \LUA\ 5.1 one which is a
+relative easy operation. Because \LUAJIT\ can address less memory than regular
+\LUA\ it will always be a matter of testing if \LUAJITTEX\ can be used instead of
+\LUATEX. Standard document processing (reports and such) is normally no problem
+but processing large amounts of data from databases can be an issue.
+
+In the process of cleaning up the code base for sure we will also find ways to
+make things run even smoother. But, in any case, version 0.80 is already a good
+benchmark for what can be achieved.
+
+\stopsection
+
+\startsection[title=Nodes]
+
+One of the bottlenecks in the hybrid approach is crossing the so called C
+boundary. This is not really a bottleneck, unless we're talking of many millions
+of function calls. In practice this only happens in for instance more extreme
+font handling (Devanagari or sometimes Arabic). If performance is really an issue
+one can fallback on a more direct node access model. Of course the overhead of
+access should be compared to other related activities: one can gain .25 seconds
+on a run in using the direct access model, but if the whole runs takes 25
+seconds, it can be neglected. If the price paid for it is less readable code it
+should only be done deep down a macro package where no user even sees the code.
+We use this access model in the \CONTEXT\ core modules and so far it looks quite
+okay, especially for more extensive manipulations. The gain in speed is quite
+noticeable if you use the more advanced features of \CONTEXT.
+
+There can be some changes in the node model but not that drastic as the current
+model is quite ok and also stays close to original \TEX\ so that existing
+documentation still applies. One of the changes will be that glue spec (sub)nodes
+will disappear and glue nodes will carry that information. Direction whatsits
+will become first class nodes as they are part of the concept (whatsits
+normally relate to extensions) and the same might happen with image nodes. As a
+side effect we can restructure the code so that it becomes more readable. Some
+experimental \PDFTEX\ functionality will be removed as it can be done better with
+callbacks.
+
+\stopsection
+
+\startsection[title=The parbuilder and HZ]
+
+As we started from \PDFTEX\ we inherit also its experimental code and character.
+One of the objectives is to separate font- and backend as good as possible. We
+have already achieved a lot and apart from bringing consistency in the code, the
+biggest change has been a partial rewrite of the hz code, especially the way
+fonts are managed. Instead of making copies of fonts with different properties,
+we now carry information in the relevant nodes. The backend code already got away
+from multiple fonts by using transformation of the base font instead of
+additional font instances, so this was a natural adaptation. This was actually
+triggered by the fact that a \LUA\ based par builder demonstrated that this made
+sense. The new approach uses less memory and is a bit faster (at least in
+theory).
+
+In callbacks it makes life easier when a node list has a predictable structure.
+For instance, the result of a paragraph broken into lines still has discretionary
+nodes. Is that really needed? Lines can have left- or rightskip nodes, depending
+on the fact if they were set. Math nodes can disappear as part of a cleanup in
+the line break code, but this is unfortunate when one expects them to be
+somewhere in the list in a callback. All this will be made consistent. These are
+issues we will look into on the way to version 1.0.
+
+I occasionally play with the \LUA\ based par builder and it is quite compatible
+even if we take the floating point \LUA\ aspect into account. However when using
+hz the outcome is different: sometimes better, sometimes worse. Personally I
+don't care too much as long as it's consistent. Features like hz are for special
+cases anyway and can never be stable over years if only because fonts evolve. And
+we're talking of bordercase typesetting: narrow columns that no matter what method is
+used will never look okay. \footnote {Some people don't like larger spaces, others
+don't like stretched glyphs.}
+
+\stopsection
+
+\startsection[title=The backend]
+
+The separation of front- and backend is more a pet project. There is some
+experimental code that will get removed or integrated. We try to make the backend
+consistent from the \TEX\ as well as \LUA\ end and some is reflected in
+additional features and callbacks.
+
+Some of the variables that can be set (the \LUA\ counterparts of the \type {\pdf..}
+token registers at the \TEX\ end) are now consistent with each other and avoid
+going via pseudo tokenization.  Typical aspects of a backend that only a few users
+will notice but nevertheless needed work.
+
+The merge of engines also resulted in inconsistencies in function names, like using
+\type {pdf_} in function names where nothing \type {PDF} is involved.
+
+\stopsection
+
+\startsection[title=Backlinks]
+
+In callbacks we mostly deal with node lists. At the \TEX\ end of course we also
+have these lists but there it is quite clear what gets done with them. This means
+that there is no need for double linked lists. It also means that what is known
+as the head of a list can in fact be in the middle. The for \TEX\ characteristic
+nesting model has resulted in stacks and current pointers. The code uses so
+called temp nodes to point at the head node.
+
+As a consequence in \LUATEX, where we present a double linked list, before the
+current version one could run into cases where for instance a head node had a
+prev pointer, even one that made no sense. As said, no big deal in \TEX\ but in
+the hands of a user who manipulates the node list it can be dramatic. The current
+version has cleaned head nodes as well as consistent backlinks, but of course we
+keep the internals mostly unchanged because we stay close to the Knuthian
+original when possible. \footnote {Even with extensions the original
+documentation still covers most of what happens.}
+
+\stopsection
+
+\startsection[title=Properties]
+
+Sometimes you want to associate additional information to a node. A natural way
+to do this is attributes. These can be set at the \TEX\ and \LUA\ end and
+accessed at the \LUA\ end. At the \LUA\ end one can have tables with nodes as
+indices and store extra information but that has the disadvantage that one has no
+clue if such information is current: nodes come and go and are recycled.
+
+For this reason we now have a global properties table where each allocated node
+can have a table with whatever information users might like to store. This itself
+is not special, but the nice thing is that when a node is freed, that information
+is also freed. So, you cannot run into old data. When nodes are copied its
+properties are also copied. The overhead, when not used, is close to zero, which is
+always an objective when extending the core engine.
+
+Of course this model demands that macro package somehow controls consistent use
+but that is not different from what already has to be done. Also, simple
+extensions like this avoid hard codes solutions, which is also something we want
+to avoid.
+

+\startsection[title=\LUA\ calls]
+
+We have so called user nodes that can carry a number, string, token list or node
+list. We now have added \LUA\ to this repertoire. In fact, we now could use only a
+\LUA\ variable and we might have done so in retrospect, but for the moment we we
+stick to the current model of several basic types. The \LUA\ variable can be
+anything and it is up to the user (in some callback) to deal with them.
+
+User nodes are not to be confused with late \LUA\ nodes. You can store a function
+call in a user node but that's about it. You can at a later moment decide to call
+that function but it's still an explicit action. The value of a late \LUA\ node
+on the other hand is dealt with automatically during shipout. When the value is a
+string it gets interpreted as \LUA, but new is that when the value is a function
+it will get called. At that moment we have access to some of the current backend
+properties, like locations.
+
+\stopsection
+
+\startsection[title=Artefacts]
+
+Because \LUATEX\ took code from \PDFTEX, that is built upon \ETEX, which in turn
+is an extension to \TEX, and \OMEGA, that also extends \TEX, there is code that
+no longer makes sense for us. Combine that with the fact that some code carries
+signatures of translated \PASCAL\ to \CCODE, we have some cleanup to do as follow
+up on the not to be underestimated move to \CCODE. This is an ongoing process but
+also fun doing. Luigi and I spend many hours exploring venues and have
+interesting Skype sessions that can easily sidetrack, and with Taco getting more
+time for \LUATEX\ we expect to get most of our (still growing) todo list done.
+
+Because \LUATEX\ started out as an experiment, there is some old code around. For
+instance, we used to have multiple instances and this still shows in some places.
+We can simplify the \LUA\ to \TEX\ interface a bit and clean up the \LUA\ global
+state handling, but we're not in a big hurry with this. Experiments have been
+done with some extensions to the writer code but they are hold back to after the
+cleanup.
+
+In a similar fashion we have sped up the way \LUA\ keyword and values get
+resolved. Already early in the development we did this for critical code like
+passing \LUA\ font tables to \TEX, followed by accessing nodes, but now we have
+done that for most code. There is still some to do but it has the side effect of
+not only consistency but also of helping to document the interface. Of course we
+learn a lot about the \LUA\ internals too. The C macro system is of great help
+here, although the mentioned pascal conversion (web2c) and merged engines have
+resulted in some inconsistency that needs to be cleaned up before we start
+documenting more of the internals (another subproject we want to finish before
+retirement).
+
+\stopsection
+
+\startsection[title=Callbacks]
+
+There are a few more callbacks and most of them come from the tracker. The
+backend now has page related callbacks, the \LUA\ error handler can be
+intercepted. Error messages that consist of multiple pieces are handled better
+too. When a file is opened and closed a callback is now possible. Technically we
+could have combined this with the already present callbacks but as in \TEX\
+synchronization matters these new callbacks relate to current message callbacks
+that show \type {[]}, \type {{}}, \type {<>} and|/|or \type {<<>>} fenced
+filenames, where the later were introduced in successive backend code.
+
+\stopsection
+
+\startsection[title=\LUA]
+
+We currently use \LUA\ 5.2 but a next version will show up soon. Because \LUA\
+5.3 introduces a hybrid number model, this will be one of the next things to play
+with. It could work out well, because \TEX\ is internally integer based (scaled
+points) but you never know. It could be that we need to check existing code for
+serialization and printing issues but normally that will not lead to
+compatibility issues. We could even decide to stick to \LUA\ 5.2 or at least wait
+till all has stabilized. There is some basic support for \UTF\ in 5.3 but in
+\CONTEXT\ we don't depend on that. In practice hardly any processing takes place
+that assumes that \UTF\ is more than a sequence of bytes and \LUA\ can handle
+bytes quite well.
+
+\stopsection
+
+\startsection[title=\CONTEXT]
+
+Of course the development of \LUATEX\ has consequences for \CONTEXT. For
+instance, existing code is used to test alternative solutions and sometimes these
+make it into the core. Some new features are used immediately, like the more
+consistent control over \PDF\ properties, but others have to wait till the new
+binary is more widespread. \footnote {Normally dissemination is rather fast
+because the contextgarden provides recent binaries. The new windows binaries
+often show up within hours after the repository has been updated.}
+
+Some of the improvement in the code base directly relate to \CONTEXT\ activities.
+For instance the \CRITED\ project (complex critical editions) uncovered some
+hashing issues with \LUAJIT\ that have been taken care of now. The (small)
+additions to the \PDF\ backend resulted in a partial cleanup of relatively old
+\CONTEXT\ backend code.
+
+Although some more complex mechanisms, like multi|-|columns are being reworked,
+it is still needed to open up a bit more of the \TEX\ internals, so we have some
+work to do. As usual, version 0.80 doesn't mean that only 0.20 has to be done to
+get to 1.00, as development is not a linear process. The jump from 0.77 to 0.79
+for instance involved a lot of work (exploration as well as testing). But as long
+as it's fun to do, time doesn't matter much. As we've said before: we're in no
+hurry.

+
+\startsection[reference=introduction,title={Introduction}]
+
+This is just another story of \TEX\ meeting \METAPOST. This time we will focus on
+charts, especially flowcharts. In \CONTEXT\ flowchart support is not part of the
+core functionality, but is provided as a module. Therefore, before you can
+actually define a chart, this module must be loaded:
+
+\starttyping
+\usemodule[chart]
+\stoptyping
+
+Once loaded, you has access to the functionality described here. Before we go
+into detail on the features, we will say some words on history.
+
+When dealing with graphics, it makes sense to use a drawing program. In fact,
+before we started using this module, we did use such programs, and they have
+without doubt their advantages. As soon as \CONTEXT\ supported interactive
+documents, there were means to make graphics interactive, and as long as only a
+few graphics are involved, this mechanism works ok.
+
+And then we suddenly had to make a document with thousands of pages and hundreds
+of often rather complicated flowcharts. Because these charts were tightly
+integrated in the main document, they not only had to be consistent in the use of
+fonts, but also had to be interactive and were to be presented both as a whole
+and in subchart parts. We wanted fonts, colors and the overall appearance as well
+as names of people, places, steps, activities and more to be consistent,
+especially because these charts are constantly updated.
+
+I use the term flowchart here because I want to stress that this module typesets
+charts which cells are connected by lines (often arrows). Our first application
+of this module concerned diagrams that expressed actions and relations between
+those actions, using some techniques originating years ago in programming
+environments: lines were not to cross, one should read from top to bottom and
+left to right, etc. However, the module presented here can be used to draw all
+kind of charts, and all kind of connections. But there are limits.
+
+{\em This manual is mostly the one written of end 1998 when the flowchart module
+showed up in the distribution. In the meantime the code has been rewritten for
+\MKIV\ and some functionality is adapted. But the interface hasn't changed much.}
+
+\stopsection
+
+\startsection[title={The grid}]
+
+A flowchart consists of shapes, positioned on a grid, connected by lines. The
+grid enables the user to anchor the shapes and enables the drawing routines to
+determine connections. One can either explicitly specify the grid, or let it be
+calculated automatically.
+

+\stopFLOWchart
+\stopbuffer
+
+\placefigure
+  [here][fig:grid]
+  {The grid.}
+  {\getbuffer[grid]\FLOWchart[grid]}
+
+Normally the grid is not visible, unless one enters test mode. The grid in \in
+{figure} [fig:grid] is the result of the definition:
+
+\typebuffer[grid]
+
+The most straightforward way of calling up this chart is by saying:
+
+\starttyping
+\FLOWchart[grid]
+\stoptyping
+
+In \in {figure} [fig:grid] we see a grid an dwithin each cell a shape. Normally
+shapes are smaller than grid cells. This is necessary because connecting lines
+need some room. The offset is important, because when a connection follows the
+outer lines, a little extra space outside that line not only looks better, but
+also prevents the line from being clipped. It makes sense to keep the offset as
+well as the space between shapes constant across a document. The numbers are
+typeset outside the bounding box of the figure.
+
+Grid cells are numbered from top to bottom starting at the left side, so the left
+topmost cell is $(1,1)$. Later we will see that because cells have names, these
+numbers play a minor role.
+
+\stopsection
+
+\startsection[title={Shapes}]
+
+A shape is something, typically a text, within a frame. The frame has certain
+dimensions and can have some color and background. In this respect it looks like
+the \CONTEXT\ command \type {\framed}. The most important shapes have been
+assigned names as indicated in \in {figure} [fig:shapes]. There are more shapes,
+but they are identified by a number only. The total number of shapes will quite
+certainly increase. The shapes {\em up}, {\em down}, {\em left} and {\em right}
+are not really shapes, but lines that can be used to force a direction.

+A flow chart consists of cells. Each cell has a name, is positioned somewhere on

+is drawn by \METAPOST, and the text is placed by \TEX. Later we will see that
+there are some more fields to fill. Names are local to a chart.

+Shapes can be connected. As shown in \in {figure} [fig:points] each shape has
+four connection points: top, bottom, left and right. When connecting shapes we
+refer to their logical names and specify two of the four directions.

+curves and run across the grid lines. By using smooth curves, an option that can
+be turned off, the direction of touching curves is always clear. Here we use
+arrows. Smoothing, arrows and dashed lines are some of the attributes of lines.

+  {\tx\setupFLOWcharts[dot=con]\FLOWchart[two]}
+
+There can be more than one connection per shape. When defining such a connection
+we first specify the direction. In this example \type {[rl]} means connect the
+right point to the left one, while \type {[tr]} results in a connection between
+the top and the right point. The second argument specifies the shape to connect
+to. As we can see, connections can point back to their origin shape.

+
+The connection drawing routines have a rather strong urge to follow grid lines.
+\in {Figure} [fig:straight] demonstrates this several times. From the first shape
+to the third one, we see that the connection takes the shortest route possible
+without crossing other shapes. I have to admit that the routines in themselves
+are rather stupid, but for normal use they suffice.

+Generally speaking, when two lines end at the same point, it makes sense to

+that they don't touch. In this respect, \in {figure} [fig:white] demonstrates a
+less than optimal chart.

+\startsection[title={Inheritance}]
+
+When explaining something by using a chart, we often show successive versions of
+the chart, where each version adds a new feature. To prevent us from retyping the
+same components again and again, it helps to partition the source code of the
+complete chart into subcharts. Inclusion of a part is straightforward: the
+subchart is called by name and positioned on the grid.

+\startsection[title={How it works}]
+
+The charting module, loaded by \type {\usemodule[chart]} is only responsible for
+the \TEX\ part of the job, which means positioning text and graphics generated by
+\METAPOST. The grid, shape and connection drawing routines are grouped together
+in a dedicated \METAPOST\ module.
+
+Because of the mix of \TEX\ and \METAPOST, and because we want to be able to
+scale charts, the buffer mechanism is used. The communication between \TEX\ and
+\METAPOST\ uses the \METAPOST\ embedding macros that are native to \CONTEXT.
+Additional communication from \METAPOST\ to \CONTEXT\ is handled in the module
+itself. This rather fuzzy description is visualized in \in {figure}
+[fig:process]. Depending on the general color settings, among the other processes
+involved are: color conversion and|/|or reduction to grayscales, and conversion
+to \PDF. When watching this module in action, don't feel disturbed by the many
+steps involved.

+Sometimes charts can become rather large, due to the many shapes used or lines

+
+Defining such a chart is not so much harder than previous cases. Each left,
+right, top and bottom point has two companion points: positive and negative. In
+connections the left points are: \type {pl}, \type {l} and \type {nl}: positive
+left, left and negative left, so the first cell in \in {figure} [fig:bonus 1] is
+defined as:
+
+\starttyping
+\startFLOWcell
+  \name       {tex}
+  \location   {1,1}
+  \shape      {action}
+  \text       {\TEX}
+  \connection [prpl] {pdf}
+  \connection [nrnl] {dvi}
+\stopFLOWcell
+\stoptyping
+
+Alternatively to \type {p} and \type {n} one may use \type {+} and \type {-}. As
+soon as the positive and negative points are used, the connection drawing
+routines will take into account the fact that they are off||center. This does not
+free users from thinking about better ways to draw such a chart.
+
+\stopsection
+
+\startsection[title={Clip and focus}]
+
+The flowcharter automatically calculates the size of the grid. When needed, one
+can force the dimensions and/or clip pieces of a chart. \in {Figure}
+[fig:clipped] shows such a clip. This example also shows why the offset, the
+small area around the outer grid lines, is important. \in {Figure} [fig:clipped]
+was produced while the next settings were in action.
+

+\placefigure

+  {Clipping a piece of a chart.}
+  {\tx\getbuffer[clip]\FLOWchart[connect]}
+
+Sometimes, for instance when explaining a chart, it makes sense to emphasize one
+or more particular cells. Therefore this module offers the ability to focus on
+cells. In \in {figure} [fig:focus] we see that the focus is on the cell with name
+\type {dvi}. This is accomplished by saying:
+
+\startbuffer
+\setupFLOWfocus
+  [framecolor=pragmacolor]
+\setupFLOWcharts
+  [focus=dvi]
+\stopbuffer
+
+\typebuffer
+
+\placefigure
+  [here][fig:focus]
+  {Gaining some focus.}
+  {\tx\getbuffer\FLOWchart[bonus 3]}
+
+Clipping and focus bring us to the third way of zooming in: autofocus. \in
+{Figure} [fig:autofocus] shows what happens when we say:
+
+\startbuffer
+\setupFLOWfocus
+  [framecolor=pragmacolor]
+\setupFLOWcharts
+  [focus=dvi,autofocus=dvi,
+   nx=1,ny=1]
+
+\startFLOWchart [bonus 3]

+  {\tx\getbuffer\FLOWchart[bonus 3]}
+
+In \in {figure}[fig:autofocus] we see both focus and auto focus in action.
+
+\stopsection
+
+\startsection[title={Line types}]
+
+As is to be expected, we can set up some characteristics of a chart, the shapes,
+the connecting lines, and the focus. When we want dashed lines and a different
+shape color, we just say:
+
+\startbuffer
+\setupFLOWshapes
+  [framecolor=pragmacolor]
+\setupFLOWlines
+  [framecolor=pragmacolor,
+   dash=yes]
+\stopbuffer
+
+\typebuffer
+
+\placefigure
+  [here][fig:lines]
+  {Dashed and colored lines.}
+  {\tx\getbuffer\FLOWchart[bonus 3]}
+
+We can change the characteristics at several levels: chart, line, shape and|/|or
+focus. In the near future some more options will be added. Once the \METAPOST\
+module is stable and documented, the graphic code will also be accessible. The
+formal definition of the four setup commands is as follows (these diagrams
+conform the \CONTEXT\ conventions):
+
+\setup{setupFLOWcharts}
+
+\setup{setupFLOWfocus}
+
+\setup{setupFLOWlines}
+
+\setup{setupFLOWshapes}
+
+\stopsection
+
+\startsection[title={Overlays}]
+
+Why should we limit ourselves to text? In \CONTEXT\ most frames||related features
+can have overlays. Because in this flowchart module shapes are drawn by
+\METAPOST, we use a slightly different approach: there can be overlays but they
+are sort of clipped by the shape. \in {Figure} [fig:overlay] illustrates this.
+

+
+There are two commands related to overlays. In our example we used: which
+automatically scales figure {\em cow} to the shape size. The normal rules for
+overlays apply. The width and height of the overlay are available at the moment
+the overlay is typeset.
+
+The text is aligned differently in this example and driven by an optional
+argument that can take one of the following values: \type {l}, \type {r}, \type
+{m}, \type {c}, \type {t}, \type {b}, \type {lt}, \type {rt}, \type {mt}, \type

+\startsection[title={Splitting charts}]
+
+Sometimes a chart does not fit comfortably on the page. In such cases, it makes
+sense to split up the chart. There is a dedicated setup command to serve
+splitting:
+
+\setup{setupFLOWsplit}
+
+An example of splitting is:
+
+\starttyping
+\setupFLOWsplit
+  [nx=5,ny=10,
+   dx=1,dy=1,
+   before=,after=\page]
+
+\FLOWcharts[mybigflow]
+\stoptyping
+
+For easy alignment of the split pages, cut marks are added. This can be turned
+off by setting \type {marking} to \type {off}. The \type {n} parameters determine
+the number of cells per split off subject, and the \type {d} parameters specify
+the overlap: a value of~1 means that each split off subject has one row and|/|or
+columns in common with its neighbour.
+
+The splitter can be used with the split float placement macro:
+
+\starttyping
+\splitfloat
+  {\placefigure{What a big flowchart this is!}}
+  {\FLOWcharts[mybigflow]}
+\stoptyping
+
+Here every flowchart gets an caption with a decent subnumber.
+
+Related to splitting up charts is the option to define exit points as
+demonstrated in the next chart.

+premature.
+
+Crossing lines, which are often forbidden in charts, can be made less confusing
+by adding a gap in the lines to be crossed. This is one of the features that are
+already implemented but not yet accessible by the \CONTEXT\ user interface.
+
+Another feature, used in this document, concerns automatic down||scaling. As soon
+as we start scaling illustrations, we introduce inconsistent typography,
+especially in the bodyfontsize. Therefore, the flow chart macros, when told to,
+are able to automatically scale down in steps of 1~point.

+\startsection[title=Color models]
+
+When you work with displays, and most of us do, the dominant color model is \RGB.
+As far as I know \CMYK\ electrowetting displays are still not in production and
+even there the \CMYK\ seems to have made place for \RGB\ (at least in promotion
+movies). This is strange since where \RGB\ is used in cases where colors are
+radiated, \CMYK\ shows up in reflective situations (and epub readers are just
+that). But \RGB\ and \CMYK\ being complementary is not the only difference:
+\CMYK\ has an explicit black channel, and as a consequence you cannot go from one
+to the other color space without loss.
+
+In print \CMYK\ is dominant but in order to get real good colors you can go with
+spot colors. The ink is not mixed with others but applied in more or less
+quantity. A mixture of spot colors and \CMYK\ is used too. You can combine spot
+colors into a so called multitone color. Often spot colors have names (for
+instance refering to Pantone) but they always have a specification in another
+color space in order to be shown on screen. Think of \quotation {gold} being a
+valid ink, but hard to render on screen, so some yellowish replacement is used
+there when documents get prepared on screen.
+
+In \CONTEXT\ all these models are supported, either or not at the same time. In \MKII\
+you had to turn on color support explicitly, if only because of the impact of the
+overhead on performance, but in \MKIV\ color is on by default. You can disable it
+with:
+
+\starttyping
+\setupcolors
+  [state=stop]
+\stoptyping
+
+The three mentioned models are controlled by keys, and by default we have set:
+
+\starttyping
+\setupcolors
+  [rgb=yes,
+   cmyk=yes,
+   spot=yes]
+\stoptyping
+
+Spot colors and their combinations in multitone colors are controlled by the same
+parameter. You can define colors in the \HSV\ color space but in the end these
+become and behave like \RGB.
+
+\stopsection
+
+\startsection[title=Using color]
+
+Normally you will use colors grouped. Most environments accept a \type {color}
+parameter (some have \type {textcolor} or similar longer names too). In a running
+text you can use:
+
+\starttyping
+\color[red]{This will show up red.}
+\stoptyping
+
+or:
+
+\starttyping
+\startcolor[red]
+    This will show up red.
+\stopcolor
+\stoptyping
+
+In case you don't want the grouping you can use:
+
+\starttyping
+\directcolor[red]
+\stoptyping
+
+You can even use:
+
+\starttyping
+\colored[r=0.5]{also red}
+\stoptyping
+
+In which case an anonymous color is used. An ungrouped variant of this is:
+
+\starttyping
+\directcolored[r=0.5]
+\stoptyping
+
+You will seldom use these direct variants, but they might come in handy when you
+write macros yourself where extra grouping starts interfering. In fact, it often
+makes sense to use a bit more abstraction:
+
+\startbuffer
+\definehighlight
+  [important]
+  [color=red]
+
+First \highlight[important]{or} second \important {or} third.
+\stopbuffer
+
+\typebuffer
+
+This gives: \inlinebuffer .
+
+\stopsection
+
+\startsection[title=Using \CMYK\ or \RGB]
+
+When you compare colors in different color spaces, you need to be aware of the
+fact that when a black component is used in \CMYK, conversion to \RGB\ might give
+the same results but going back from that to \CMYK\ will look different from the
+original. Also, \CMYK\ colors are often tuned for specific paper.

+\startsection[title=Conversion]
+
+A conversion to gray happens when \RGB\ and \CMYK\ are both disabled. The following
+setting forces conversion. It disables both \RGB\ and \CMYK:
+
+\starttyping
+\setupcolors
+  [conversion=always]
+\stoptyping
+
+The default setting is \type {yes} which means that colors will be reduced to gray in
+the backend. This is an optimization which can result in slightly smaller output:
+

+
+The conversion to gray is controlled by:
+
+\starttyping
+\setupcolors
+  [factor=yes]
+\stoptyping
+
+Like \type {conversion} the \type {factor} is a global setting. You can play with the factor values.
+The default (\type {yes}) uses the factors used by color television:
+
+\startformula
+    s = 0.30r + 0.59g + 0.11b
+\stopformula
+
+In \in {figure} [color:demo:gray] we demonstrate what happens when you use different
+values. Normally you won't change the defaults but for experimenting we do provide
+the option:
+
+\starttyping
+\setupcolors
+  [factor=0.20:0.40:0.40]
+\stoptyping
+
+There is one pitfall. Colors are finalized per page and as this is a backend
+feature the value current when a page is shipped out is used. An exception are
+\METAPOST\ graphics, as they have local resources and are finalized immediately.
+This is hardly a limitation because one will never set these numbers in the
+middle of a document.

+% let's take a break and watch: https://www.youtube.com/watch?v=baLrrW3El-M
+
+\startsection[title=Definitions]
+
+The mostly used color definition command is \type {\definecolor}. Here we define the
+primary colors:
+
+\startbuffer
+\definecolor [red]     [r=1]
+\definecolor [green]   [g=1]
+\definecolor [blue]    [b=1]
+\definecolor [yellow]  [y=1]
+\definecolor [magenta] [m=1]
+\definecolor [cyan]    [c=1]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+These can be visualized as follows:
+
+\startbuffer
+\showcolorcomponents[red,green,blue,yellow,magenta,cyan,black]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Transparency is included in these tables but is, as already noted, in fact
+independent. It can be defined with a color:
+
+\startbuffer
+\definecolor [t:red]   [r=1,a=1,t=.5]
+\definecolor [t:green] [g=1,a=1,t=.5]
+\definecolor [t:blue]  [b=1,a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This time the transparency values show up too:
+
+\showcolorcomponents[t:red,t:green,t:blue]
+
+Because transparency is separated from color, we can define transparent behaviour
+as follows:
+
+\startbuffer
+\definecolor[t:only] [a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+    \dontleavehmode
+    \blackrule[width=4cm,height=1cm,color=darkgreen]%
+    \hskip-2cm
+    \color[t:only]{\blackrule[width=4cm,height=1cm,color=darkred]}%
+    \hskip-2cm
+    \color[t:only]{\blackrule[width=4cm,height=1cm]}
+\stopbuffer
+
+\typebuffer
+
+We skip back to create an overlay, so we get:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+In the section about transparency a bit more will be said about the relation between
+color and transparencies and how to cheat.
+
+As soon as you need to typeset something for professional printing, spot colors
+will show up so they are supported too. A spot color is not really a color but
+related to the substance that gets put on the paper. This can be ink but also
+something metallic, like silver, gold or some texture. In these cases we need
+something to represent it when not printed on a suitable device so again we end
+up with a color. This is reflected in the way spot colors are set up.
+
+\startbuffer
+\definecolor     [parentspot]               [r=.5,g=.2,b=.8]
+\definespotcolor [childspot-1] [parentspot] [p=.7,e=fancy]
+\definespotcolor [childspot-2] [parentspot] [p=.4]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The three colors, two of them are spot colors, show up as follows:
+
+\setupcolors[spot=yes]
+
+\showcolorcomponents[parentspot,childspot-1,childspot-2]
+
+The \type {p} is comparable to the \type {s} in gray scales. The \type {e}
+parameter can be used to specify a name for the color. In the \PDF\ file that
+name will become the separation name (a popular commercial naming scheme is
+Pantone).
+
+A combination of spotcolor is called a multitone color. These are defined as
+follows (we also define a few spotcolors and use transparency):
+
+\startbuffer
+\definespotcolor [spotone]   [darkred]   [p=1]
+\definespotcolor [spottwo]   [darkgreen] [p=1]
+
+\definespotcolor [spotone-t] [darkred]   [a=1,t=.5]
+\definespotcolor [spottwo-t] [darkgreen] [a=1,t=.5]
+
+\definemultitonecolor
+    [whatever]
+    [spotone=.5,spottwo=.5]
+    [b=.5]
+
+\definemultitonecolor
+    [whatever-t]
+    [spotone=.5,spottwo=.5]
+    [b=.5]
+    [a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\showcolorcomponents[spotone,spottwo,spotone-t,spottwo-t,whatever,whatever-t]
+
+Transparencies combine as follows:
+
+\startbuffer
+\blackrule[width=3cm,height=1cm,color=spotone-t]\hskip-1.5cm
+\blackrule[width=3cm,height=1cm,color=spotone-t]
+\stopbuffer

+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+In case you want to specify colors in the \HSV\ color space, you can do that too.
+The hue parameter (\type {h}) is in degrees and runs from 0 upto 360 (larger
+values get divided). The saturation (\type {s}) and value (\type {v}) parameters
+run from 0 to 1. The \type {v} parameter is mandate. In \in {figure} [fig:hsv] we
+show what the last two variables do.

+\startsection[title=Palets]
+
+Color palets are handy when you want to use a set of (named) colors but
+also want to switch efficiently between different definitions:
+

+\definepalet
+  [standard]
+  [darkred=darkcyan,
+   darkgreen=darkmagenta,
+   darkblue=darkyellow]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \type {\setuppalet} commands switches to a palet. When a requested color is
+not part of a palet, a regular lookup happens. This is used as:
+
+\startbuffer
+\blackrule[width=15mm,height=10mm,depth=0mm,color=darkred]\quad
+\blackrule[width=15mm,height=10mm,depth=0mm,color=darkgreen]\quad
+\blackrule[width=15mm,height=10mm,depth=0mm,color=darkblue]\quad
+\setuppalet[standard]%
+\blackrule[width=15mm,height=10mm,depth=0mm,color=darkred]\quad
+\blackrule[width=15mm,height=10mm,depth=0mm,color=darkgreen]\quad

+Here we use color names but often you end up with more symbolic names:
+
+\starttyping
+\definepalet
+  [standard]
+  [important=darkred,
+   notabene=darkgreen,
+   warning=darkyellow]
+\stoptyping
+
+As with the regular color commands, the palet mechanism is an old one but it is
+well integrated. Instead of inheriting you can also use definitions:
+
+\starttyping
+\definepalet
+  [standard]
+  [important={r=.5},
+   notabene={g=.5},
+   warning={r=.5,g=.5}]
+\stoptyping
+
+\stopsection
+
+\startsection[title=Transparency]
+
+We already discussed transparency as part of colors. In most cases we will choose
+type {normal} (or \type {1}) as transparency type, but there are more:
+
+\startluacode
+    local codes = table.swapped(attributes.transparencies.names)

+\stopplacefigure
+
+Colors and transparencies are coupled by definitions. We will explain this by
+some examples. When we say:
+
+\startbuffer
+\definecolor[clr1][r=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+A non|-|transparent color is defined and when we say:
+
+\startbuffer
+\definecolor[clr2][g=.5,a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We defined a color with a transparency. However, color and transparency get separated
+attributes. So when we nest them as in:
+
+\startbuffer
+\color[clr1]{\bf RED   \color[clr2] {GREEN}}
+\color[clr2]{\bf GREEN \color[clr1] {RED}  }
+\stopbuffer
+
+\typebuffer
+
+we get:
+
+\startlines \getbuffer \stoplines
+
+The transparency of the outer color is also applied to the inner color. If you
+don't want that, you explicitly need to set them:
+
+\startbuffer
+\definecolor[clr3][b=.5,a=1,t=1]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\color[clr1]{\bf RED   \color[clr2] {GREEN} \color[clr3]{BLUE} }
+\color[clr2]{\bf GREEN \color[clr1] {RED}   \color[clr2]{GREEN}}
+\color[clr3]{\bf BLUE  \color[clr1] {RED}   \color[clr2]{GREEN}}
+\stopbuffer
+
+\typebuffer
+
+we get:
+
+\startlines \getbuffer \stoplines
+
+If you define a transparent|-|only color, you get transparent black:
+
+\startbuffer
+\definecolor[clr4][a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+So:
+
+\startbuffer
+\color[clr1]{\bf RED    \color[clr4] {RED}}
+\color[clr4]{\bf BLACK  \color[clr1] {RED}}
+\stopbuffer
+
+\typebuffer
+
+gives:
+
+\startlines \getbuffer \stoplines
+
+In addition to the already discussed definers and setters we also have a few
+special ones. Personally I never needed them but they are the for completeness.
+
+\startbuffer
+\definetransparency[tsp1][a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We apply this to some text:
+
+\startbuffer
+\color      [clr1]{\bf RED   \transparent[tsp1] {RED}   }
+\transparent[tsp1]{\bf BLACK \color      [clr1] {RED}   }
+\transparent[tsp1]{\bf BLACK \transparent[reset]{BLACK} }
+\stopbuffer
+
+\typebuffer
+
+and get:
+
+\startlines \getbuffer \stoplines
+
+We can also only switch color:
+
+\startbuffer
+\color[clr1]{\bf RED \color    [clr2] {GREEN}}
+\color[clr1]{\bf RED \coloronly[clr2] {GREEN}}
+\stopbuffer
+
+\typebuffer
+
+So the second line has no transparency:
+
+\startlines \getbuffer \stoplines
+
+The \typ {\starttransparent} and \type {\startcoloronly} commands are the
+complements of \typ {\transparent} and \typ {\coloronly}.

+Although it is not perfect, \PDF\ evolved in such a way that it will stay around

+
+\startsection[title=Unboxing]
+
+This paragraph is somewhat complex, so skip it when you don't feel comfortable
+with the subject or when you've never seen low level \CONTEXT\ code.
+
+Colors are implemented using attributes. Attributes behave like fonts. This means
+that they are kind of frozen once material is boxed. Consider that we define a
+box as follows:
+
+\startbuffer
+\setbox0\hbox{\bf default {\darkred red \darkgreen green} default}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+What do you expect to come out the next code? In \MKII\ the \quote {default}
+inside the box will be colored yellow but the internal red and and green words
+will keep their color.
+
+\startbuffer
+\bf default {\darkyellow yellow {\box0} yellow} default
+\stopbuffer
+
+\typebuffer
+
+This is what we get in \MKIV: \start \inlinebuffer \stop
+
+When we use fonts switches we don't expect the content of the
+box to change. So, in the following the \quote {default} texts will
+{\em not} become bold.
+
+\startbuffer
+\setbox0\hbox{default {\sl slanted \bi bold italic} default}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+default {\bf bold {\box0} bold} default
+\stopbuffer
+
+\typebuffer
+
+Now we get: \inlinebuffer .
+
+Redoing a box with a new font is sort of tricky as by then all kind of
+manipulations have been applied and the original inputs is long gone. But colors
+are easier to deal with and therefore in \MKIV\ we have a trick to make sure the
+outer color gets applied to the box:
+
+\startbuffer[enable]
+\enabledirectives
+  [attributes.inheritance]
+\stopbuffer
+
+\startbuffer
+default {\bf \darkyellow yellow {\attributedbox0} yellow} default
+\stopbuffer
+
+\typebuffer
+
+So, we get: \start\inlinebuffer[box]\inlinebuffer[enable]\space\inlinebuffer
+\stop, but only after we have enabled this mechanisms explicitly:
+
+\typebuffer[enable]
+
+There is also an \type {\attributedcopy} macro. These macros signal the attribute
+resolver that this box is to be treated special.
+
+In \MKII\ we have a similar situation which is why we had the option (only used
+deep down in \CONTEXT) to encapsulate a bunch of code with
+
+\starttyping
+\startregistercolor[foregroundcolor]
+some macro code ... here foregroundcolor is applied ... more code
+\stopregistercolor
+\stoptyping
+
+This is for instance used in the \type {\framed} macro. First we package the
+content, foregroundcolor is not yet applied because the injected specials of
+literals can interfere badly, but by registering the colors the nested color
+calls are tricked into thinking that preceding and following content is colored.
+When packaged, we apply backgrounds, frames, and foregroundcolor to the whole
+result. Because nested colors were aware of the foregroundcolor they have
+properly reverted to this color when needed.
+
+In \MKIV\ the situation is reversed. Here we definitely need to set the
+foregroundcolor because otherwise attributes are not set. This is no problem
+because contrary to \MKII\ colors don't interfere (no extra nodes). We could have
+flushed the framed content using \type {\attributedbox}, but we don't want to
+enable inheritance by default because it comes with some overhead.
+
+\stopsection
+
+\startsection[title=Color intents]
+
+If we do this:
+
+\startbuffer
+\startoverlay
+    {\blackrule[color=darkred, height=2cm,width=4cm]}
+    {\blackrule[color=darkblue,height=1cm,width=3cm]}
+\stopoverlay
+\stopbuffer
+
+\typebuffer
+
+we get:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+The blue rectangle is drawn on top of the red one. In print, normally the
+printing engine will make sure that there is no red below the blue. In case of
+transparent colors this is somewhat tricky because then we definitely want to see
+part of what lays below.
+
+You can control this process with the following commands:
+
+\starttyping
+\setupcolors
+  [intent=...]
+\stoptyping
+
+The default setting is \type {none} but you can set the intent to \type {overprint} or
+\type {knockout} as well. In a running text you can use the following commands:
+
+\starttyping
+\startcolorintent[overprint|knockout]
+    ...
+\stopcolorintent
+
+\startoverprint
+    ...
+\stopoverprint
+
+\startknockout
+    ...
+\stopknockout
+\stoptyping
+
+In practice you will probably seldom need to deal with this so best leave the defaults
+as they are.
+
+\stopsection
+
+\startsection[title=Collections]
+
+Collections are predefined sets of colors. You find them in the files \type
+{colo-imp-*.mkiv} and you can make such files yourself. When you define a color a
+command is generated by default. When you load a collection, there is a danger
+that you redefine commands unintended. For that reason most collections are
+wrapped in:
+
+\starttyping
+\startprotectedcolors
+    % definitions
+\stopprotectedcolors
+\stoptyping
+
+This prevents commands being defined and assumes that colors are accessed by
+using the \type {color} parameter of setup commands or in the text with:
+
+\starttyping
+\color[somecolor]{this gets colored}
+
+\startcolor[somecolor]
+    this gets colored
+\stopcolorintent
+\stoptyping
+
+The default set (\type {rgb}) is already preloaded with:
+
+\starttyping
+\usecolors[rgb] % preloaded
+\stoptyping
+
+You can get a list of colors with
+
+\startbuffer
+\showcolor[rgb]
+\stopbuffer
+
+\typebuffer
+
+This generates the list:
+
+\getbuffer
+
+These are the collections shipped with \CONTEXT. Some names are
+
+\starttabulate[|T||]
+\NC crayola \NC crayon colors \NC \NR
+\NC dem     \NC a demo set of groups and palets \NC \NR
+\NC ema     \NC an old coming from an Emacs user \NC \NR
+%NC pan     \NC a bunch of Pantone colors \NC \NR % can't be distributed

+\NC x11     \NC (most of the) standard X11 \RGB\ colors \NC \NR
+\stoptabulate
+
+You can look in these files to see what gets defined. Even if you don't use them
+they might be illustrative,
+
+\stopsection
+
+\startsection[title=Text color]
+
+Setting the color of the running text is done with:
+
+\starttyping
+\setupcolors
+  [textcolor=darkgray]
+\stoptyping
+
+If needed you can also set the \type {pagecolormodel} there but its default value
+is \type {none} which means that it will obey the global settings.
+
+\stopsection
+
+\startsection[title=Tikz]
+
+In case you use the TikZ graphical subsystem you need to be aware of the the fact
+that its color support is more geared towards \LATEX. There is glue code that
+binds the \CONTEXT\ color system to its internal representation but there can
+still be problems. For instance, not all color systems are supported so \CONTEXT\
+will try to remap, but only when it knows that it has to do so. You can best not
+mix colorspaces when you use TikZ. If you really want (and there is no real
+reason to do so) you can say:
+
+\starttyping
+\enabledirectives[colors.pgf]
+\stoptyping
+
+and then (at the cost of some extra overhead) define colors as:
+
+\starttyping
+\definecolor[pgfcolora][blue!50!green]
+\definecolor[pgfcolorb][red!50!blue]
+\stoptyping
+
+\stopsection
+
+\startsection[title=Implementation details]
+
+The low level implementation of colors in \MKIV\ is fundamentally different from
+\MKII. In \MKIV\ something like this happens:
+
+\starttyping
+one \color[red]{two} three
+\stoptyping
+
+becomes (with grouping):
+
+\starttyping
+one {<start color: red>two<stop color>} three
+\stoptyping
+
+the start and stop points are in fact injections in the input: a special (for
+\DVI) or literals (for \PDF) is inserted that turns the color on and off, but
+also information is carried along about the state of color, so that we can
+properly nest as well as pick up the current color after a page break. We never
+had real problems with this mechanism but one had to keep in mind that injections
+like this could interfere with typesetting. This mechanism didn't rely on the
+engine for housekeeping, all was done at the \TEX\ end using so called marks.
+
+In \MKIV\ we use attributes. This means that the sequence now looks like:
+
+\starttyping
+one {<set color attribute to red>two} three
+\stoptyping
+
+The actual handling of color happens when a page is shipped out and there is no
+interference with typesetting. The work is mostly done in \LUA.
+
+Colorspaces (\RGB, \CMYK, spot) were already supported in \MKII\ and of course
+still are in \MKIV. However, the colorspace is now a more independent property.
+At some point in \MKII\ we also implemented transparency as a property of a
+color. In \MKIV\ transparency is still defined with a color but handled
+independently. This means that where in \MKII\ color is just one axis, in \MKIV\
+we have three: colorspace (model), color and transparency. This of course has a
+bit of a performance and memory hit, but in practice a user won't notice it.
+
+\stopsection
+
+\startsection[title=Grouping]
+
+The \type {\color} and \type {\startcolor} command group their arguments. There might
+be cases where this interferes with your intentions, for instance when you want to
+set some variable and use its value later on.
+
+\startbuffer
+1 \scratchcounter=1
+plus
+1 \advance \scratchcounter by 1
+equals
+\the\scratchcounter
+\stopbuffer
+
+\typebuffer
+
+The summation works out okay: {\bf \inlinebuffer}.
+
+\startbuffer
+\color[darkblue]{1 \scratchcounter=1}
+plus
+\color[darkblue]{1 \advance \scratchcounter by 1}
+equals
+\color[darkgreen]{\the\scratchcounter}
+\stopbuffer
+
+\typebuffer
+
+Here the final result depends on the value of \type {\scratchcounter}:
+{\scratchcounter 3 \bf \inlinebuffer}.
+
+\startbuffer
+\start
+    \pushcolor[darkblue]1 \scratchcounter=1 \popcolor
+    plus
+    \pushcolor[darkblue]1 \advance \scratchcounter by 1 \popcolor
+    equals
+    \pushcolor[darkgreen]\the\scratchcounter \popcolor
+\stop
+\stopbuffer
+
+\typebuffer
+
+Here we get: {\bf \inlinebuffer}. The \typ {\pushcolor} and \typ {\popcolor}
+commands can be used nested which give a bot of overhead. The \typ {\savecolor}
+and \typ {\restorecolor} commands are variants that don't stack. They are a bit
+more efficient but if you use them nested you probably also will use some
+grouping. Where the push||pop pair needs to be matched, the save||restore pair
+doesn't impose that restriction.
+
+\stopsection
+
+\startsection[title=Commands]
+
+There are quite some commands that relate to colors but you probably only need
+\typ {\definecolor}, \type {\color} and \typ {\startcolor} \unknown \typ
+{\stopcolor}. Here we show the complete list. Some commands are redundant, for
+instance \typ {\definenamedcolor} is the same as \typ {\definecolor}.

+\startchapter[title=Graphics][color=darkblue]
+
+\startsection[title=Conversion]
+
+There is not that much to tell about graphics and color simply because from the
+perspective of \TEX\ a graphic is just a blob with dimensions that travels
+through the system and in the backend gets included as|-|is. This means that when
+there is a problem with an image you have to go back to the source of that image
+and fix it there.
+
+It can happen that you need to manipulate an image and in a fully automated
+workflow that can be cumbersome. For that reason \CONTEXT\ has a mechanism for
+converting graphics.
+
+\startluacode
+    context.starttabulate { "|BT|T|" }
+    context.NC() context.bold("original")
+    context.NC() context.bold("target")
+    context.NC() context.NR()
+    for k, v in table.sortedhash(figures.converters) do
+        context.NC() context(k)
+        context.NC() context("%{\\quad }t",table.sortedkeys(v))
+        context.NC() context.NR()
+    end
+    context.stoptabulate()
+\stopluacode
+
+Some of these converters are applied automatically. For instance if you include
+an \type {eps} image, \CONTEXT\ will try to convert it into a \PDF\ file and only
+do that once (unless the image changed). Of course it needs a conversion program,
+but as long as you have GhostScript, GraphicMagick and InkScape on your machine
+it should work out well.
+
+You can also define your own converters (we use a verbose variant):
+
+\starttyping
+\startluacode
+    -- of course we need options
+
+    local resolutions = {
+        [interfaces.variables.low]    = "150x150",
+        [interfaces.variables.medium] = "300x300",
+        [interfaces.variables.high]   = "600x600",
+    }
+
+    figures.programs.lowrespng = {
+        command  = "gm",
+        argument = [[convert -resample %resolution% "%oldname%" "%newname%"]],
+    }
+
+    figures.converters["png"]["lowres.png"] = function(oldname,newname,resolution)
+        runprogram (
+            figures.programs.lowrespng.command,
+            figures.programs.lowrespng.argument,
+            {
+                oldname    = oldname,
+                newname    = newname,
+                resolution = resolutions[resolution] or "150x150"
+            }

+\startsection[title=Profiles]
+
+Color profiles are used to control the printing process. There is some (limited)
+support for that built in. An example of a setup that we use in a project is the
+following:
+
+\starttyping
+\setupexternalfigures
+  [order={pdf,eps,png,jpg},
+   conversion=cmyk.pdf,
+   method=auto]
+\stoptyping
+
+So, we prefer \PDF\ vector images, if needed converted from \EPS. When there is
+no vector image we check for a \PNG\ and as last resort for a \JPG. The
+\type{method} is set to \type {auto} which means that we check if the image file
+indeed is reflected in the suffix. This is needed because in a workflow with tens
+of thousands of images there can be bad ones.
+
+The \type {conversion} parameter will make \CONTEXT\ check if there is a \type
+{cmyk.pdf} converter defined and when that is the case, it's applied. That
+specific converter will add a color profile to the image. You can set the
+profiles with:
+
+\starttyping
+\enabledirectives[graphics.conversion.rgbprofile=srgb.icc]
+\enabledirectives[graphics.conversion.cmykprofile=isocoated_v2_eci.icc]
+\stoptyping
+
+and these happens to be the defaults. You have to make sure that the files are
+present, preferable in \type{t:/texmf/colors/icc/context}. If you add profiles
+you need to make sure that \type {colorprofiles.lua} is updated accordingly.
+
+Just for completeness, in our situation, we also have set:
+
+\starttyping
+\enabledirectives[graphics.conversion.eps.cleanup.ai]
+\enabledirectives[graphics.extracheck]
+\stoptyping
+
+The first directive will make sure that confusing sections (for instance meant to
+the drawing program) are stripped from an \EPS\ file, and the second one forces
+some extra checking on the image (just to make sure that the engine doesn't exit
+on bad images).

+\startchapter[title=Introduction][color=darkgray]
+
+This manual fits in the series where we discus fundamental subsystems like fonts
+and languages. Here we will collect the more technical backgrounds. This document
+is not meant as a manual for users who start with \CONTEXT, for that we have
+other manuals.
+
+Color has a rather long history in \CONTEXT\ because we supported it right from
+the start. In the times that \DVI\ backend drivers were used, specials were the
+way to force color in the result. However, each driver had different demands:
+some expected specific color directives, others a sequence of for instance
+\POSTSCRIPT\ commands. When \PDF\ showed up, resource management entered the
+game. Because ot always used a backend driver model in \CONTEXT, it could easily
+be adapted. All management, for instance of nested colors, was done in \TEX\
+code. If advanced color support hadn't been available right from the start, we'd
+probably not be using \TEX\ now.
+
+In \MKIV\ color support was implemented from scratch but in a for the user
+downward compatible way. In that respect this manual is not going to reveal
+anything revolutionary. Much of the work is now delegated to \LUA\ and because of
+that directives are no longer part of the (expanded) input stream. As a result
+color is now more robust and less intrusive.
+
+Because \METAPOST\ support is well integrated, we also communicate colors to
+\METAPOST. In \MKIV\ the communication between the two engines was upgraded and
+hopefully evolved into an (even) more convenient interface.
+
+External graphics are in fact islands in the document flow: they manage their
+resources like colors themselves. However, there are some ways to deal with the
+demands of publishers and printers with respect to colors. These will be
+discussed too.

+\startsection[title=Defining and using]
+
+In \METAPOST\ itself colors are defined as numbers or sets:
+
+\starttyping
+color     red  ; red  := (1,0,0) ;
+cmykcolor cyan ; cyan := (1,0,0,0) ;
+numeric   gray ; gray := 0.5 ;
+\stoptyping
+
+You don't need much fantasy to see that this fits well in the data model of
+\METAPOST. In fact, transparency could be represented as a \type {pair}. The
+disadvantage of having no generic color type is that you cannot mix them. In case
+you need to manipulate them, you can check the type:
+
+\starttyping
+if cmykcolor cyan : ... fi ;
+\stoptyping
+
+because \METAFUN\ is tightly integrated in \CONTEXT\ you can refer to colors
+known at the \TEX\ end by string. So,
+
+\starttyping
+string mycolor ; mycolor := "red" ;
+\stoptyping
+
+and then:
+
+\starttyping
+fill fullcircle scaled 4cm withcolor mycolor ;
+\stoptyping
+
+is quite okay. For completeness we also have \type {namedcolor} but it's not
+really needed:
+
+\starttyping
+fill fullcircle scaled 4cm withcolor namedcolor("red");
+\stoptyping
+
+You can define spot colors too but normally you will refer to colors
+defined at the \TEX\ end.
+
+\startbuffer[spot]

+    fill fullcircle scaled 3cm withcolor
+        .5 * spotcolor("whatever",(.3,.4,.5)) ;

+\startsection[title=Passing colors]
+
+Originally \TEX\ and \METAPOST\ were separated processes and even in \LUATEX\
+they still are. There can be many independent \METAPOST\ instances present, but
+always there is \LUA\ as glue between them. In the early days of \LUATEX\ this
+was a one way channel: the \METAPOST\ output is available at the \TEX\ end in
+\LUA\ as a table and properties are used to communicate extensions. In today's
+\LUATEX\ the \METAPOST\ library has access to \LUA\ itself so that gives us a
+channel to \TEX, although with some limitations.
+
+Say that we have a color defined as follows:
+
+\startbuffer
+\definecolor[MyColor][r=.25,g=.50,b=.75]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can apply this to a rule:
+
+\startbuffer
+\blackrule[color=MyColor,width=3cm,height=1cm,depth=0cm]
+\stopbuffer
+
+\typebuffer
+
+From this we get:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+In \TEX\ (code) we can do this:
+
+\startbuffer
+\startMPcode
+    fill unitsquare xyscaled (3cm,1cm) withcolor \MPcolor {MyColor} ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+When the code is pushed to \METAPOST\ the color gets expanded, in this case to
+\typ {(0.25, 0.50, 0.75)} because we specified an \RGB\ color but the other
+colorspaces are supported too.
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+Equally valid code is:
+
+\starttyping
+\startMPcode
+    fill unitsquare xyscaled (3cm,1cm) withcolor "MyColor" ;
+\stopMPcode
+\stoptyping
+
+This is very un-\METAPOST\ as naturally it can only deal with numerics for gray
+scales, triplets for \RGB\ colors, and quadruplets for \CMYK\ colors. In
+\METAFUN\ (as present in \CONTEXT\ MKIV) the \type {withcolor} operator also
+accepts a string, which is resolved to a color specification.
+
+For the record we note that when you use transparent colors, a more complex
+specification gets passed with \type {\MPcolor} or resolved (via the string). The
+same is true for spot and multitone colors. It will be clear that when you want
+to assign a color to a variable you have to make sure the type matches. A rather
+safe way to define colors is:
+
+\starttyping
+def MyColor =
+    \MPcolor{MyColor}
+enddef ;
+\stoptyping
+
+and because we can use strings, string variables are also an option.
+
+\stopsection
+
+\startsection[title=Grouping]
+
+The reason for discussing these details is that there is a rather fundamental
+concept of grouping in \TEX\ which can lead to unexpected side effects. The
+reason is that there is no grouping at the \LUA\ end, unless one uses a kind of
+stack, and that in \METAPOST\ grouping is an explicit feature.
+
+\starttyping
+\scratchcounter=123
+\bgroup
+    \scratchcounter=456
+\egroup
+\stoptyping
+
+After this \TEX\ code is expanded the counter has value 123. In \METAPOST\ you
+can do the following:
+
+\starttyping
+scratchcounter := 123 ;
+\begingroup
+    scratchcounter := 456 ;
+\endgroup
+\stoptyping
+
+but here the counter is 456 afterwards! You explicitly need to save a value:
+
+\starttyping
+scratchcounter := 123 ;
+\begingroup
+    save scratchcounter ;
+    numeric scratchcounter ; % variables are numeric by default anyway
+    scratchcounter := 456 ;
+\endgroup
+\stoptyping
+
+The difference perfectly makes sense if you think about the kind of applications
+\TEX\ and \METAPOST\ are used for. In \LUA\ you can do this:
+
+
+\starttyping
+scratchcounter = 123
+do
+    local scratchcounter = 456
+end
+\stoptyping
+
+and in fact, a \type {then}, \type {else}, \type {while}, \type {repeat}, \type
+{do} and function body also behave this way.
+
+So, what is the impact on colors? Imagine that you do this:
+
+\startbuffer
+\bgroup
+    \definecolor[MyColor][s=.5]
+    \startMPcode
+        pickup pencircle scaled 4mm ;
+        draw fullcircle scaled 30mm withcolor \MPcolor{MyColor} ;
+        draw fullcircle scaled 15mm withcolor "MyColor" ;
+    \stopMPcode
+\egroup
+\quad
+\startMPcode
+    pickup pencircle scaled 4mm ;
+    draw fullcircle scaled 30mm withcolor \MPcolor{MyColor} ;
+    draw fullcircle scaled 15mm withcolor "MyColor" ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+We get the following colors:
+
+\startlinecorrection
+\hbox{\getbuffer}
+\stoplinecorrection
+
+Because \type {\MPcolor} is a \TEX\ macro, its value gets expanded when the
+graphic is calculated. After the group (first graphic) the color is restored.
+But, in order to access the colors defined at the \TEX\ end in \METAPOST\ by name
+(using \LUA) we need to make sure that a defined color is registered at that end.
+Before we could use the string accessor in \METAPOST\ colors, this was never a
+real issue. We kept the values in a (global) \LUA\ table which was good enough
+for the cases where we wanted to access color specifications, for instance for
+tracing. Such colors never changed in a document. But with the more dynamic
+\METAPOST\ graphics we cannot do that: there is no way that \METAPOST\ (or \LUA)
+later on can know that the color was defined inside a group as clone. For daily
+usage it's enough to know that we have found a way around it in \CONTEXT\ at
+neglectable overhead. In the rare case this mechanism fails, you can always
+revert to the \type {\MPcolor} method.

+There are two macros that can be used to resolve string to colors: \type
+{resolvedcolor} and \type {namedcolor}. A resolved color is expanded via \LUA\
+while a named color is handled in the backend, when the result is converted to
+\PDF. The resolved approach is more recent and is the same as a string color
+specification.

+
+We get:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+The drawback of this approach is that, because we use so called pre- and
+postscripts for achieving special effects (like spotcolors and shading)
+successive \type {withcolor} calls can interfere in a way that unexpected results
+turn up. A way out is to use properties:
+
+\startbuffer
+\startMPcode
+    property p[] ;
+    p1 = properties(withcolor "darkred") ;
+    p2 = properties(withcolor "white") ;
+    fill fullcircle scaled 4cm withproperties p1 ;
+    fill fullcircle scaled 3cm withproperties p2 ;

+%             with existing functionality and we cannot be held responsible for that. Many of
+%             the manuals contain characteristic graphics and personal notes or examples that
+%             make no sense when used out-of-context.
+%
+% comment   : Some chapters might have been published in TugBoat, the NTG Maps, the ConTeXt
+%             Group journal or otherwise. Thanks to the editors for corrections. Also thanks
+%             to users for testing, feedback and corrections.

+
+This manual introduces {\em column sets}, one of the output routines of \CONTEXT.
+Although column sets are mainly meant for typesetting journals in a
+semi||automated way, you can also use them for books. We assume that the user is
+familiar with \CONTEXT\ and only discuss the commands that are related to column
+sets.
+
+This mechanism performs okay but it needs to be used with care: an occasional
+manual intervention is needed to get optimal results. After all, we're operating
+in the area where normally click and point desktop publishing is used.
+
+{\bf For the moment you need to load the new code with: \type{\usemodule[newcolumnsets]}}

+
+\startchapter[title=Basics]
+
+As soon as enough content is collected to build a page, \TEX\ will invoke the
+output routine. This is not a fixed piece of code, but a collection of macro
+calls. The default output routine is a meant for typesetting a single column, as
+in this document. A multi||column output routine is available as well. This
+routine mixes well with the single column one, and is activated by:
+
+\starttyping
+\startcolumns
+some text ...
+\stopcolumns
+\stoptyping
+
+In \MKIV\ a new mixed column mechanism has been introduced that will be
+developped further and eventually replace the old multi column handler. In \MKII\
+there is also a columnset mechanism that can be used to construct complex multi
+column pages. In \MKIV\ this gets replaced by grid columns. All these multi
+column mechanisms have in common that the output routine is more complex because
+now a page is in fact a collection of pages wrapped onto one. Each column is
+(from \TEX's perspective) similar to a one narrow column page. Here we focus on
+columnsets (page grids).
+
+There are some limitations to what you can do with this kind of multi columns,
+which is why we have a third routine at out disposal: {\em column sets}. This
+routine can be used for rather complex layouts with graphics all over the place,
+and text spanning columns or even spreads. There are of course some shortcomings,
+which we will discuss later.
+
+In the examples that follow we use the following style to set up the layout. The
+number in the margin serves a reference to the file where this snippet of \TEX\
+is stored.
+
+\ShowEnvironmentFile{columnsets-000}
+
+\page[mine]
+
+Before we will demonstrate more complex layouts, we will introduce a few
+features. In the next series of examples we use fake text. You can enlarge the
+pages in your viewer if you want to see more detail.
+
+\FourSpread{columnsets-001}
+
+These pages were typeset with the following code:
+
+\ShowFile{columnsets-001}
+
+We will showmost examples on a spread, so we don't show a first page. On a
+spread like above we number columns from~1 to~4, which in practice means that in
+this case columns starting on right page start with column~3!
+
+\SixPages{columnsets-001}
+
+\page[mine]
+
+The number of columns is not fixed to two. You can even have a different number
+of columns on left and right pages.
+
+\FourSpread{columnsets-002}
+
+This time the input is:
+
+\ShowFile{columnsets-002}
+
+Again, we started on a right page but showed the spreads. You can see it from the
+positioning of the header texts.
+
+\SixPages{columnsets-002}
+
+\page[mine]
+
+In order to get the balancing you want, you can manually influence the height of
+a column.
+
+\FourSpread{columnsets-003}
+
+When you set the number of column lines to a positive value, that will be the
+number of lines. A negative value will be subtracted from the maximum number of
+lines.
+
+\ShowFile{columnsets-003}
+
+\page[mine]
+
+In articles you may want to let the introduction span multiple columns. A column
+span is defined independent of a column set and shows up as follows:
+
+\FourSpread{columnsets-004}
+
+Here we've given the span a background so that it stands out.
+
+\ShowFile{columnsets-004}
+
+\page[mine]
+
+A column span can be positioned like any graphic. Later we will discuss the
+placement options in more detail, for the moment all you need to know is that
+\type {btlr} tells \CONTEXT\ to place the graphic in the left bottom of the the
+text area.
+
+\FourSpread{columnsets-005}
+
+Here we pass the \type {default} placement as parameter to the span, but you can
+also set it at definition time. We use a brute force simple column splitter to
+fake columns inside the span.
+
+\ShowFile{columnsets-005}
+
+\page[mine]
+
+You are not limited to one column span. In this sense a span is like a graphic:
+as long as there is room, it will be placed where you want it to be placed. The
+main difference between a span and a graphic is that a span expects text and
+tries to align the baselines with the rest of the text. In many ways a column
+span behaves like a framed text.
+
+\FourSpread{columnsets-006}
+
+This time we flushed one of the spans from bottom to top, starting at the right
+edge: \type {btrl}.
+
+\ShowFile{columnsets-006}
+
+\page[mine]
+
+Column spans are treated like graphics, which means that they will float if
+needed. In the process, the width is limited to the available space, which in
+some cases may lead to a smaller span than you may expect. Think of a column
+span, calculated (and prepared) in the last column and ending up on the next page
+in the first column, where a broader span would have been possible.
+
+\FourSpread{columnsets-007}
+
+\ShowFile{columnsets-007}
+
+\stopchapter
+
+\startchapter[title=Graphics]
+
+Most documents have graphics, and therefore column sets can contain them. The
+main thing that you have to keep in mind when placing graphics, is that column
+sets are based on grids. Therefore spacing around graphics is also grid based.
+
+\FourSpread{columnsets-101}
+
+\ShowFile{columnsets-101}
+
+\page[mine]
+
+You can tell \CONTEXT\ where it should place the graphic, but this will only be
+honored when there is still place.
+
+\EightSpread{columnsets-102}
+
+The prefered location is passed as a four character directive:
+
+\ShowFile{columnsets-102}
+
+\page[mine]
+
+The following directives are available:
+
+\starttabulate[|lT|p|]
+\NC btlr     \NC flush from bottom to top    and left to right  \NC \NR
+\NC btrl     \NC flush from bottom to top    and right to left  \NC \NR
+\NC tblr     \NC flush from top    to bottom and left to right  \NC \NR
+\NC tbrl     \NC flush from top    to bottom and right to left  \NC \NR
+\NC lrbt     \NC flush from left   to right  and bottom to top  \NC \NR
+\NC lrtb     \NC flush from left   to right  and top to bottom  \NC \NR
+\NC rlbt     \NC flush from right  to left   and bottom to top  \NC \NR
+\NC rltb     \NC flush from right  to left   and top to bottom  \NC \NR
+\NC here     \NC try to place the graphic here                  \NC \NR
+\NC fixd     \NC force the graphic here and don't float         \NC \NR
+\NC fxtb:c*r \NC place the graphic at (c,r) or lower if needed  \NC \NR
+\NC fxbt:c*r \NC place the graphic at (c,r) or higher if needed \NC \NR
+\NC tops     \NC place the graphic at the top of the page       \NC \NR
+\NC bots     \NC place the graphic at the bottom of the page    \NC \NR
+\NC page     \NC place the graphic at a separate page           \NC \NR
+\stoptabulate
+
+In the next example we show the directional locations:
+
+\OneSpread{columnsets-103}

+\stopchapter
+
+\startchapter[title=Areas]
+
+So far we have seen texts and graphics that span multiple columns using span
+commands and floats placement commands. We have also seen that you can define a
+different number of columns for left and right pages. Now that we have arrives at
+column areas you will see how we can span information over not only a page but
+also over pages in a spread.
+
+\FourSpread{columnsets-201}
+
+Being a framed text, by default an area is aligned at the baseline. You can lower
+an area by setting the \type {location} to \type {depth}.
+
+\ShowFile{columnsets-201}
+
+\page[mine]
+
+You can position areas on the left, right or next page or on both pages. When you
+set \type {state} to \type {repeat}, an area is repeated, otherwise it is only
+placed once.
+
+\FourSpread{columnsets-202}
+
+Here we just repeat the areas. Normally this only make sense when the content is
+worth repeating.
+
+\ShowFile{columnsets-202}
+
+\page[mine]
+
+Areas can span a spread, as is demonstrated in the next example.
+
+\FourSpread{columnsets-203}
+
+\ShowFile{columnsets-203}
+
+\page[mine]
+
+An application of a spread area is a title. In the next example we show two
+spread pages.
+
+\FourSpread{columnsets-204}
+
+Watch how we explicitly go to a left page.
+
+\ShowFile{columnsets-204}
+
+\page[mine]
+
+The \type {\GapText} macro is an experimental fun macro and is used to make sure
+that we don't end up with a clipped character.
+
+\startlinecorrection[blank]
+\startcombination
+  {\scale[width=.4\textwidth]{\clip
+     [nx=2,ny=6,x=2,y=2]
+     {\typesetfile[columnsets-204.tex][page=2]}}}
+  {left page}
+  {\scale[width=.4\textwidth]{\clip
+     [nx=2,ny=6,x=1,y=2]
+     {\typesetfile[columnsets-204.tex][page=3]}}}
+  {right page}
+\stopcombination
+\stoplinecorrection
+
+This is a typical example of the kind of optimizations that are needed when you
+make documents of styles with text that spans a spread. In the next clip we
+visualize the gap.
+
+\startlinecorrection[blank]
+\startcombination
+  {\scale[width=.4\textwidth]{\clip
+     [nx=2,ny=6,x=2,y=2]
+     {\typesetfile[columnsets-205.tex][page=2]}}}
+  {left page}
+  {\scale[width=.4\textwidth]{\clip
+     [nx=2,ny=6,x=1,y=2]
+     {\typesetfile[columnsets-205.tex][page=3]}}}
+  {right page}
+\stopcombination
+\stoplinecorrection
+
+At some moment you may want to set up an area in advance as we have done in the
+following example.
+
+\FourSpread{columnsets-206}
+
+The \type {page} key is used to specify the page in the column set that the area
+should go into. Column set pages start numbering at~1. The \type {fixed} stands
+for left or right, whatever comes first.
+
+\ShowFile{columnsets-206}
+
+\stopchapter
+
+\startchapter[title=Columns]
+
+You can use \type {\page} to go to a new page in a column set. Likewise you can
+use \type {\column} to force a column break.
+
+\FourPages{columnsets-301}
+
+This example demonstrates that you can supply \type {\column} with explicit
+directives.
+
+\ShowFile{columnsets-301}
+
+You can use \type {\column[page]} as an alternative for \type {\page}.
+
+\stopchapter
+
+\startchapter[title=Details]
+
+This chapter will cover a couple of cosmetic details of column sets. {\em Some
+features need to be improved, especially in combination with areas, graphics and
+alike. We will also provide side floats etc.}
+
+\FourSpread{columnsets-401}
+
+You can set the distance between columns for each pair of columns. {\em Todo:
+left and right page distances and margins.}
+
+\ShowFile{columnsets-401}
+
+\page[mine]
+
+When you can the distance of the first column as well. This creates a margin.
+
+\FourSpread{columnsets-402}
+
+This time we used equal distances:
+
+\ShowFile{columnsets-402}
+
+\page[mine]
+
+The width of columns is normally calculated automatically, but you can also set
+the width explicitly:
+
+\FourSpread{columnsets-403}
+
+In code:
+
+\ShowFile{columnsets-403}
+
+\page[mine]
+
+For special effects, you can set the width per column. In that case you need to
+be aware of the fact that \TEX\ works its way through the document per paragraph.
+Changing the width halfway a paragraph is possible but will affect the whole
+paragraph. Therefore, this feature works best when you also goto the next column
+explicitly.
+
+\FourSpread{columnsets-404}
+
+In code:
+
+\ShowFile{columnsets-404}
+
+\page[mine]
+
+If you really want to change the width in the middle of a paragraph, you can do a
+trial run and include a breakpoint at the palce where you want it to occur:
+
+\FourSpread{columnsets-405}
+
+In the second spread you see how the narrow hsize carries on in the wider
+column. A \type {\column} command will synchronize the hsize.

+\startchapter[title=Directions]
+
+\FourSpread{columnsets-601}
+
+The direction of flushing columns is determined by the \type {direction}
+parameters as demonstrated below.

+\stopchapter
+
+\startchapter[title=Backgrounds]
+
+As with many \CONTEXT\ components, column sets can have backgrounds.
+
+\FourSpread{columnsets-701}
+
+Watch how we use the \type {each} keyword to tell \CONTEXT\ that we want to apply
+the background to each column of the set.
+
+\ShowFile{columnsets-701}
+
+\page[mine]
+
+Normally, if you apply backgrounds this way, you will also set the background
+offset. In a similar fashion you can apply backgrounds to areas and spans. Such
+backgrounds can be a color, or any overlay or layer you want.
+
+\FourSpread{columnsets-702}
+
+Here we've set the background offset as well as the frame.
+
+\ShowFile{columnsets-702}
+
+\page[mine]
+
+When dealing with areas, you need to be aware of the fact that they are clipped,
+the content as well as the background.
+
+\FourSpread{columnsets-703}
+
+De default clip offset is two times the lineheight, except in the binding, where
+it is set to zero points. You can set the clip offset with the \type {clipoffset}
+parameter.
+
+\ShowFile{columnsets-703}
+
+\page[mine]
+
+The text background mechanism is rather well adapted to column sets. The

+\startchapter[title={Backend code}]
+
+\startsection [title={Introduction}]
+
+In \CONTEXT\ we've always separated the backend code in so called driver files.
+This means that in the code related to typesetting only calls to the \API\ take
+place, and no backend specific code is to be used. That way we can support
+backend like dvipsone (and dviwindo), dvips, acrobat, pdftex and dvipdfmx with
+one interface. A simular model is used in \MKIV\ although at the moment we only
+have one backend: \PDF. \footnote {At this moment we only support the native
+\PDF\ backend but future versions might support \XML\ (\HTML) output as well.}
+
+Some \CONTEXT\ users like to add their own \PDF\ specific code to their styles or
+modules. However, such extensions can interfere with existing code, especially
+when resources are involved. This has to be done via the official helper macros.
+
+In the next sections an overview will be given of the current approach. There are
+still quite some rough edges but these will be polished as soon as the backend
+code is more isolated in \LUATEX\ itself.
+
+\stopsection
+
+\startsection [title={Structure}]
+
+A \PDF\ file is a tree of indirect objects. Each object has a number and the file
+contains a table (or multiple tables) that relates these numbers to positions in
+a file (or position in a compressed object stream). That way a file can be viewed
+without reading all data: a viewer only loads what is needed.
+
+\starttyping
+1 0 obj <<
+    /Name (test) /Address 2 0 R
+>>
+2 0 obj [
+   (Main Street) (24) (postal code) (MyPlace)
+]
+\stoptyping
+
+For the sake of the discussion we consider strings like \type {(test)} also to be
+objects. In the next table we list what we can encounter in a \PDF\ file. There
+can be indirect objects in which case a reference is used (\type{2 0 R}) and
+direct ones.
+
+\starttabulate[|l|l|p|]
+\FL
+\NC \bf type \NC \bf form \NC \bf meaning \NC \NR
+\TL
+\NC constant   \NC \type{/...} \NC A symbol (prescribed string). \NC \NR
+\NC string     \NC \type{(...)} \NC A sequence of characters in pdfdoc encoding \NC \NR
+\NC unicode    \NC \type{<...>} \NC A sequence of characters in utf16  encoding \NC \NR
+\NC number     \NC \type{3.1415} \NC A number constant. \NC \NR
+\NC boolean    \NC \type{true/false} \NC A boolean constant. \NC \NR
+\NC reference  \NC \type{N 0 R} \NC A reference to an object \NC \NR
+\NC dictionary \NC \type{<< ... >>} \NC A collection of key value pairs where the
+                   value itself is an (indirect) object. \NC \NR
+\NC array      \NC \type{[ ... ]} \NC A list of objects or references to objects. \NC \NR
+\NC stream     \NC \NC A sequence of bytes either or not packaged with a dictionary
+                   that contains descriptive data. \NC \NR
+\NC xform      \NC \NC A special kind of object containing an reusable blob of data,
+                   for example an image. \NC \NR
+\LL
+\stoptabulate
+
+While writing additional backend code, we mostly create dictionaries.
+
+\starttyping
+<< /Name (test) /Address 2 0 R >>
+\stoptyping
+
+In this case the indirect object can look like:
+
+\starttyping
+[ (Main Street) (24) (postal code) (MyPlace) ]
+\stoptyping
+
+It all starts in the document's root object. From there we access the page tree
+and resources. Each page carries its own resource information which makes random
+access easier. A page has a page stream and there we find the to be rendered
+content as a mixture of (\UNICODE) strings and special drawing and rendering
+operators. Here we will not discuss them as they are mostly generated by the
+engine itself or dedicated subsystems like the \METAPOST\ converter. There we use
+literal or \type {\latelua} whatsits to inject code into the current stream.
+
+In the \CONTEXT\ \MKII\ backend drivers code you will see objects in their
+verbose form. The content is passed on using special primitives, like \type
+{\pdfobj}, \type{\pdfannot}, \type {\pdfcatalog}, etc. In \MKIV\ no such
+primitives are used. In fact, some of them are overloaded to do nothing at all.
+In the \LUA\ backend code you will find function calls like:
+
+\starttyping
+local d = lpdf.dictionary {
+    Name    = lpdf.string("test"),
+    Address = lpdf.array {
+        "Main Street", "24", "postal code", "MyPlace",
+    }
+}
+\stoptyping
+
+Equaly valid is:
+
+\starttyping
+local d = lpdf.dictionary()
+d.Name = "test"
+\stoptyping
+
+Eventually the object will end up in the file using calls like:
+
+\starttyping
+local r = pdf.immediateobj(tostring(d))
+\stoptyping
+
+or using the wrapper (which permits tracing):
+
+\starttyping
+local r = lpdf.flushobject(d)
+\stoptyping
+
+The object content will be serialized according to the formal specification so
+the proper \type {<< >>} etc.\ are added. If you want the content instead you can
+use a function call:
+
+\starttyping
+local dict = d()
+\stoptyping
+
+An example of using references is:
+
+\starttyping
+local a = lpdf.array {
+    "Main Street", "24", "postal code", "MyPlace",
+}
+local d = lpdf.dictionary {
+    Name    = lpdf.string("test"),
+    Address = lpdf.reference(a),
+}
+local r = lpdf.flushobject(d)
+\stoptyping
+
+\stopsection
+
+We have the following creators. Their arguments are optional.
+
+\starttabulate[|l|p|]
+\FL
+\NC \bf function \NC \bf optional parameter \NC \NR
+\TL
+%NC \type{lpdf.stream}      \NC indexed table of operators \NC \NR
+\NC \type{lpdf.dictionary}  \NC hash with key/values \NC \NR

+\NC \type{lpdf.reference}   \NC string \NC \NR
+\NC \type{lpdf.verbose}     \NC indexed table of strings \NC \NR
+\LL
+\stoptabulate
+
+Flushing objects is done with:
+
+\starttyping
+lpdf.flushobject(obj)
+\stoptyping
+
+Reserving object is or course possible and done with:
+
+\starttyping
+local r = lpdf.reserveobject()
+\stoptyping
+
+Such an object is flushed with:
+
+\starttyping
+lpdf.flushobject(r,obj)
+\stoptyping
+
+We also support named objects:
+
+\starttyping
+lpdf.reserveobject("myobject")
+
+lpdf.flushobject("myobject",obj)
+\stoptyping
+
+\startsection [title={Resources}]
+
+While \LUATEX\ itself will embed all resources related to regular typesetting,
+\MKIV\ has to take care of embedding those related to special tricks, like
+annotations, spot colors, layers, shades, transparencies, metadata, etc. If you
+ever took a look in the \MKII\ \type {spec-*} files you might have gotten the
+impression that it quickly becomes messy. The code there is actually rather old
+and evolved in sync with the \PDF\ format as well as \PDFTEX\ and \DVIPDFMX\
+maturing to their current state. As a result we have a dedicated object
+referencing model that sometimes results in multiple passes due to forward
+references. We could have gotten away from that with the latest versions of
+\PDFTEX\ as it provides means to reserve object numbers but it makes not much
+sense to do that now that \MKII\ is frozen.
+
+Because third party modules (like tikz) also can add resources like in \MKII\
+using an \API\ that makes sure that no interference takes place. Think of macros
+like:
+
+\starttyping
+\pdfbackendsetcatalog       {key}{string}
+\pdfbackendsetinfo          {key}{string}
+\pdfbackendsetname          {key}{string}
+
+\pdfbackendsetpageattribute {key}{string}
+\pdfbackendsetpagesattribute{key}{string}
+\pdfbackendsetpageresource  {key}{string}
+
+\pdfbackendsetextgstate     {key}{pdfdata}
+\pdfbackendsetcolorspace    {key}{pdfdata}
+\pdfbackendsetpattern       {key}{pdfdata}
+\pdfbackendsetshade         {key}{pdfdata}
+\stoptyping
+
+One is free to use the \LUA\ interface instead, as there one has more
+possibilities. The names are similar, like:
+
+\starttyping
+lpdf.addtoinfo(key,anything_valid_pdf)
+\stoptyping
+
+At the time of this writing (\LUATEX\ .50) there are still places where \TEX\ and
+\LUA\ code is interwoven in a non optimal way, but that will change in the future
+as the backend is completely separated and we can do more \TEX\ trickery at the
+\LUA\ end.
+
+Also, currently we expose more of the backend code than we like and future
+versions will have a more restricted access. The following function will stay
+public:
+
+\starttyping
+lpdf.addtopageresources  (key,value)
+lpdf.addtopageattributes (key,value)
+lpdf.addtopagesattributes(key,value)
+
+lpdf.adddocumentextgstate(key,value)
+lpdf.adddocumentcolorspac(key,value)
+lpdf.adddocumentpattern  (key,value)
+lpdf.adddocumentshade    (key,value)
+
+lpdf.addtocatalog        (key,value)
+lpdf.addtoinfo           (key,value)
+lpdf.addtonames          (key,value)
+\stoptyping
+
+There are several tracing options built in and some more will be added in due
+time:
+
+\starttyping
+\enabletrackers
+  [backend.finalizers,
+   backend.resources,
+   backend.objects,
+   backend.detail]
+\stoptyping
+
+As with all trackers you can also pass them on the command line, for example:
+
+\starttyping
+context --trackers=backend.* yourfile
+\stoptyping
+
+The reference related backend mechanisms have their own trackers.
+
+\stopsection
+
+\startsection [title={Transformations}]
+
+There is at the time of this writing still some backend related code at the \TEX\
+end that needs a cleanup. Most noticeable is the code that deals with
+transformations (like scaling). At some moment in \PDFTEX\ a primitive was
+introduced but it was not completely covering the transform matrix so we never
+used it. In \LUATEX\ we will come up with a better mechanism. Till that moment we
+stick to the \MKII\ method.
+
+\stopsection
+
+\startsection [title={Annotations}]
+
+The \LUA\ based backend of \MKIV\ is not so much less code, but definitely
+cleaner. The reason why there is quite some code is because in \CONTEXT\ we also
+handle annotations and destinations in \LUA. In other words: \TEX\ is not
+bothered by the backend any more. We could make that split without too much
+impact as we never depended on \PDFTEX\ hyperlink related features and used
+generic annotations instead. It's for that reason that \CONTEXT\ has always been
+able to nest hyperlinks and have annotations with a chain of actions.
+
+Another reason for doing it all at the \LUA\ end is that as in \MKII\ we have to
+deal with the rather hybrid cross reference mechanisms which uses a sort of
+language and parsing this is also easier at the \LUA\ end. Think of:
+
+\starttyping
+\definereference[somesound][StartSound(attention)]
+
+\at {just some page} [someplace,somesound,StartMovie(somemovie)]
+\stoptyping
+
+We parse the specification expanding shortcuts when needed, create an action
+chain, make sure that the movie related resources are taken care of (normally the
+movie itself will be a figure), and turn the three words into hyperlinks. As this
+all happens in \LUA\ we have less \TEX\ code. Contrary to what you might expect,
+the \LUA\ code is not that much faster as the \MKII\ \TEX\ code is rather
+optimized.
+
+Special features like \JAVASCRIPT\ as well as widgets (and forms) are also
+reimplemented. Support for \JAVASCRIPT\ is not that complex at all, but as in
+\CONTEXT\ we can organize scripts in collections and have automatic inclusion of
+used functions, still some code is needed. As we now do this in \LUA\ we use less
+\TEX\ memory. Reimplementing widgets took a bit more work as I used the
+opportunity to remove hacks for older viewers. As support for widgets is somewhat
+instable in viewers quite some testing was needed, especially because we keep
+supporting cloned and copied fields (resulting in widget trees).
+
+An interesting complication with widgets is that each instance can have a lot of
+properties and as we want to be able to use thousands of them in one document,
+each with different properties, we have efficient storage in \MKII\ and want to
+do the same in \LUA. Most code at the \TEX\ end is related to passing all those
+options.
+
+You could use the \LUA\ functions that relate to annotations etc.\ but normally
+you will use the regular \CONTEXT\ user interface. For practical reasons, the
+backend code is grouped in several tables:
+
+The \type{backends} table has subtables for each backend and currently there is
+only one: \type {pdf}. Each backend provides tables itself. In the
+\type{codeinjections} namespace we collect functions that don't interfere with
+the typesetting or typeset result, like inserting all kind of resources (movies,
+attachment, etc.), widget related functionality, and in fact everything that does
+not fit into the other categories. In \type {nodeinjections} we organize
+functions that inject literal \PDF\ code in the nodelist which then ends up in
+the \PDF\ stream: color, layers, etc. The \type {registrations} table is reserved
+for functions related to resources that result from node injections: spot colors,
+transparencies, etc. Once the backend code is finished we might come up with
+another organization. No matter what we end up with, the way the \type {backends}
+table is supposed to be organized determines the \API\ and those who have seen
+the \MKII\ backend code will recognize some of it.
+
+\startsection [title={Metadata}]
+
+We always had the opportunity to set the information fields in a \PDF\ but
+standardization forces us to add these large verbose metadata blobs. As this blob
+is coded in \XML\ we use the built in \XML\ parser to fill a template. Thanks to
+extensive testing and research by Peter Rolf we now have a rather complete
+support for \PDF/x related demands. This will definitely evolve with the advance
+of the \PDF\ specification. You can replace the information with your own but we
+suggest that you stay away from this metadata mess as far as possible.
+
+\stopsection
+
+\startsection [title={Helpers}]
+
+If you look into the \type {lpdf-*.lua} files you will find more
+functions. Some are public helpers, like:
+
+\starttabulate
+\NC \type {lpdf.toeight(str)}   \NC returns \type {(string)} \NC \NR
+%NC \type {lpdf.cleaned(str)}   \NC returns \type {escaped string} \NC \NR
+\NC \type {lpdf.tosixteen(str)} \NC returns \type {<utf16 sequence>} \NC \NR
+\stoptabulate
+
+An example of another public function is:
+
+\starttyping
+lpdf.sharedobj(content)
+\stoptyping
+
+This one flushes the object and returns the object number. Already defined
+objects are reused. In addition to this code driven optimization, some other
+optimization and reuse takes place but all that happens without user
+intervention.

+\startchapter[title={The Bidi Dilemma}]
+
+Here I will introduce a few concepts of bidirectional typesetting. While \LUATEX\
+does a lot automatically, this does not mean that you get a proper bidirectional
+layout for free. We distinguish a few cases:
+
+\startitemize [packed]
+\startitem verbatim as used in manuals \stopitem
+\startitem simulating a text editor \stopitem
+\startitem typesetting of text \stopitem
+\stopitemize
+
+In addition to this we distinguish two document layouts:
+
+\startitemize [packed]
+\startitem predominantly left||to||right with some right||to||left snippets \stopitem
+\startitem predominantly right||to||left with some left||to||right snippets \stopitem
+\stopitemize
+
+In both cases explicit choices have to be made when defining the layout,
+programming the style, and coding the content. In this chapter I will stick to
+verbatim.
+
+In verbatim mode we normally use a monospaced font and no interference with
+features is to be expected. You get what you've keyed in. Because verbatim is
+used for illustrative purposes, we need to have predictable output. This is why
+we have to control the position of the linenumbers as well as the alignment
+explicitly.
+
+\startbuffer[basics]
+\definetyping [XXtyping] [numbering=line]
+\definetyping [RLtyping] [align=r2l,numbering=line]
+\definetyping [LRtyping] [align=l2r,numbering=line]
+\stopbuffer
+
+\typebuffer[basics] \getbuffer[basics]
+
+We use these definitions in the following example:
+
+\startbuffer[sample]
+\startLRtyping
+At the left!
+At the left!
+\stopLRtyping
+
+\startRLtyping
+At the right!
+At the right!
+\stopRLtyping

+\startalignment[l2r]

+\stopalignment
+
+\startalignment[r2l]
+\startXXtyping
+At the right!
+At the right!
+\stopXXtyping
+\stopalignment
+\stopbuffer
+
+\typebuffer[sample]
+
+However, we can have a bit more control over the position of the line numbers. As
+linenumbers are added in a later stage we need to define additional line number
+classes for this. We show four relevant positions of linenumbers. What setting
+you use depends on the predominant direction of your document as well as what you
+want to demonstrate.
+
+\startbuffer
+\definetyping [RLtypingLEFT] [align=r2l,numbering=line]
+\definetyping [LRtypingLEFT] [align=l2r,numbering=line]

+At the left!
+\stopLRtypingLEFT
+
+\startRLtypingLEFT
+At the right!
+At the right!
+\stopRLtypingLEFT
+\stopbuffer
+
+\typebuffer
+
+When \type {location} is set to \type {left}, the line numbers will always be in
+the left margin, no matter what the text direction is.
+
+\getbuffer
+
+\startbuffer
+\definetyping [RLtypingRIGHT] [align=r2l,numbering=line]
+\definetyping [LRtypingRIGHT] [align=l2r,numbering=line]

+At the left!
+At the left!
+\stopLRtypingRIGHT

+\startRLtypingRIGHT
+At the right!

+\stopRLtypingRIGHT

+
+From this it follows that when \type {location} is set to \type {right}, the line
+numbers will always be in the right margin.

+Again, the text direction is not influencing the placement.

+\startchapter[title={Callbacks}]
+
+\startsection [title={Introduction}]
+
+Callbacks are the means to extend the basic \TEX\ engine's functionality in
+\LUATEX\ and \CONTEXT\ \MKIV\ uses them extensively. Although the interface is
+still in development we see users popping in their own functionality and although
+there is nothing wrong with that, it can open a can of worms.
+
+It is for this reason that from now on we protect the \MKIV\ callbacks from being
+overloaded. For those who still want to add their own code some hooks are
+provided. Here we will address some of these issues.
+
+\stopsection
+
+\startsection [title={Actions}]
+
+There are already quite some callbacks and we use most of them. In the following
+list the callbacks tagged with \type {enabled} are used and frozen, the ones
+tagged \type {disabled} are blocked and never used, while the ones tagged \type
+{undefined} are yet unused.
+
+\ctxcommand{showcallbacks()}
+
+You can be rather sure that we will eventually use all callbacks one way or the
+other. Also, some callbacks are only set when certain functionality is enabled.
+
+It may sound somewhat harsh but if users kick in their own code, we cannot
+guarantee \CONTEXT's behaviour any more and support becomes a pain. If you really
+need to use a callback yourself, you should use one of the hooks and make sure
+that you return the right values.
+
+The exact working of the callback handler is not something we need to bother
+users with so we stick to a simple description. The next list is not definitive
+and evolves. For instance we might at some point decide to add more granularity.
+
+We only open up some of the node list related callbacks. All callbacks related to
+file handling, font definition and housekeeping are frozen. Most if the
+mechanisms that use these callbacks have hooks anyway.
+
+Of course you can overload the built in functionality as this is currently not
+protected, but we might do that as well once \MKIV\ is stable enough. After all,
+at the time of this writing overloading can be handy when testing.
+
+This leaves the node list manipulators. The are grouped as follows:
+
+\starttabulate[|l|l|p|]
+\FL
+\NC \bf category \NC \bf callback \NC \bf usage \NC \NR
+\TL
+\NC \type{processors}   \NC \type{pre_linebreak_filter}  \NC called just before the paragraph is broken into lines \NC \NR
+\NC                     \NC \type{hpack_filter}          \NC called just before a horizontal box is constructed \NC \NR
+\NC \type{finalizers}   \NC \type{post_linebreak_filter} \NC called just after the paragraph has been broken into lines \NC \NR
+\NC \type{shipouts}     \NC \type{no callback yet}       \NC applied to the box (or xform) that is to be shipped out \NC \NR
+\NC \type{mvlbuilders}  \NC \type{buildpage_filter}      \NC called after some material has been added to the main vertical list \NC \NR
+\NC \type{vboxbuilders} \NC \type{vpack_filter}          \NC called when some material is added to a vertical box \NC \NR
+%NC \type{parbuilders}  \NC \type{linebreak_filter}      \NC called when a paragraph is to be broken into lines \NC \NR
+%NC \type{pagebuilders} \NC \type{pre_output_filter}     \NC called when a page it fed into the output routing \NC \NR
+\NC \type{math}         \NC \type{mlist_to_hlist}        \NC called just after the math list is created, before it is turned into an horizontal list \NC \NR
+\BL
+\stoptabulate
+
+Each category has several subcategories but for users only two
+make sense: \type {before} and \type {after}. Say that you want to
+hook some tracing into the \type {mvlbuilder}. This is how it's
+done:
+
+\starttyping
+function third.mymodule.myfunction(where)
+    nodes.show_simple_list(tex.lists.contrib_head)
+end
+
+nodes.tasks.appendaction("processors", "before", "third.mymodule.myfunction")
+\stoptyping
+
+As you can see, in this case the function gets no \type {head} passed (at least
+not currently). This example also assumes that you know how to access the right
+items. The arguments and return values are given below. \footnote {This interface
+might change a bit in future versions of \CONTEXT. Therefore we will not discuss
+the few more optional arguments that are possible.}
+
+\starttabulate[|l|l|p|]
+\FL
+\NC \bf category \NC \bf arguments \NC \bf return value \NC \NR

+\NC \type{processors}   \NC \type{head, ...} \NC \type{head, done} \NC \NR

+\stopsection
+
+\startsection [title={Tasks}]
+
+In the previous section we already saw that the actions are in fact tasks and
+that we can append (and therefore also prepend) to a list of tasks. The \type
+{before} and \type {after} task lists are valid hooks for users contrary to the
+other tasks that can make up an action. However, the task builder is generic
+enough for users to be used for individual tasks that are plugged into the user
+hooks.
+
+Of course at some point, too many nested tasks bring a performance penalty with
+them. At the end of a run \MKIV\ reports some statistics and timings and these
+can give you an idea how much time is spent in \LUA. Of course this is a rough
+estimate only.
+
+The following tables list all the registered tasks for the processors actions:
+
+\ctxlua{nodes.tasks.table("processors")}
+
+Some of these do have subtasks and some of these even more, so you can imagine
+that quite some action is going on there.
+
+The finalizer tasks are:
+
+\ctxlua{nodes.tasks.table("finalizers")}
+
+Shipouts concern:
+
+\ctxlua{nodes.tasks.table("shipouts")}
+
+There are not that many mvlbuilder tasks currently:
+
+\ctxlua{nodes.tasks.table("mvlbuilders")}
+
+The vboxbuilder perform similar tasks:
+
+\ctxlua{nodes.tasks.table("vboxbuilders")}
+
+% In the future we expect to have more parbuilder tasks. Here again
+% there are subtasks that depend on the current typesetting environment, so
+% this is the right spot for language specific treatments.
+%
+% \ctxlua{nodes.tasks.table("parbuilders")}
+
+% The following actions are applied just before the list is
+% passed on the the output routine. The return value is a vlist.
+%
+% \ctxlua{nodes.tasks.table("pagebuilders")}
+
+Finally, we have tasks related to the math list:
+
+\ctxlua{nodes.tasks.table("math")}
+
+As \MKIV\ is developed in sync with \LUATEX\ and code changes from experimental
+to more final and reverse, you should not be too surprised if the registered
+function names change.
+
+You can create your own task list with:
+
+\starttyping
+nodes.tasks.new("mytasks",{ "one", "two" })
+\stoptyping
+
+After that you can register functions. You can append as well as prepend them
+either or not at a specific position.
+
+\starttyping
+nodes.tasks.appendaction ("mytask","one","bla.alpha")
+nodes.tasks.appendaction ("mytask","one","bla.beta")
+
+nodes.tasks.prependaction("mytask","two","bla.gamma")
+nodes.tasks.prependaction("mytask","two","bla.delta")
+
+nodes.tasks.appendaction ("mytask","one","bla.whatever","bla.alpha")
+\stoptyping
+
+Functions can also be removed:
+
+\starttyping
+nodes.tasks.removeaction("mytask","one","bla.whatever")
+\stoptyping
+
+As removal is somewhat drastic, it is also possible to enable and disable
+functions. From the fact that with these two functions you don't specify a
+category (like \type {one} or \type {two}) you can conclude that the function
+names need to be unique within the task list or else all with the same name
+within this task will be disabled.
+
+\starttyping
+nodes.tasks.enableaction ("mytask","bla.whatever")
+nodes.tasks.disableaction("mytask","bla.whatever")
+\stoptyping
+
+The same can be done with a complete category:
+
+\starttyping
+nodes.tasks.enablegroup ("mytask","one")
+nodes.tasks.disablegroup("mytask","one")
+\stoptyping
+
+There is one function left:
+
+\starttyping
+nodes.tasks.actions("mytask",2)
+\stoptyping
+
+This function returns a function that when called will perform the tasks. In this
+case the function takes two extra arguments in addition to \type {head}.
+\footnote {Specifying this number permits for some optimization but is not really
+needed}
+
+Tasks themselves are implemented on top of sequences but we won't discuss them
+here.
+
+\stopsection
+
+\startsection [title={Paragraph and page builders}]
+
+Building paragraphs and pages is implemented differently and has no user hooks.
+There is a mechanism for plugins but the interface is quite experimental.

+\startchapter[title={Characters with special meanings}]
+
+\startsection[title={Introduction}]
+
+When \TEX\ was designed \UNICODE\ was not yet available and characters were
+encoded in a seven or eight bit encoding, like \ASCII\ or \EBCDIC. Also, the
+layout of keyboards was dependent of the vendor. A lot has happened since then:
+more and more \UNICODE\ has become the standard (with \UTF\ as widely used way of
+efficiently coding it).
+
+Also at that time, fonts on computers were limited to 256 characters at most.
+This resulted in \TEX\ macro packages dealing with some form of input encoding on
+the one hand and a font encoding on the other. As a side effect of character
+nodes storing a reference to a glyph in a font hyphenation was related to font
+encodings. All this was quite okay for documents written in English but when
+\TEX\ became pupular in more countries more input as well as font encodings were
+used.
+
+Of course, with \LUATEX\ being a \UNICODE\ engine this has changed, and even more
+because wide fonts (either \TYPEONE\ or \OPENTYPE) are supported. However, as
+\TEX\ is already widely used, we cannot simply change the way characters are
+treated, certainly not special ones. Let's go back in time and see how plain
+\TEX\ set some standards, see how \CONTEXT\ does it currently, and look ahead how
+future versions will deal with it.
+
+\stopsection
+
+\startsection[title={Catcodes}]
+
+Traditional \TEX\ is an eight bit engine while \LUATEX\ extends this to \UTF\
+input and internally works with large numbers.
+
+In addition to its natural number (at most 0xFF for traditional \TEX\ and upto
+0x10FFFF for \LUATEX), each character can have a so called category code, or
+catcode. This code determines how \TEX\ will treat the character when it is seen
+in the input. The category code is stored with the character so when we change
+such a code, already read characters retain theirs. Once typeset a character can
+have turned into a glyph and its catcode properties are lost.
+
+There are 16 possible catcodes that have the following meaning:
+
+\starttabulate[|l|l|p|]
+\NC 0 \NC escape \NC This starts an control sequence. The scanner
+reads the whole sequence and stores a reference to it in an
+efficient way. For instance the character sequence \type {\relax}
+starts with a backslash that has category code zero and \TEX\
+reads on till it meets non letters. In macro definitions a
+reference to the so called hash table is stored. \NC \NR
+\NC 1 \NC begin group \NC This marks the begin of a group. A group
+an be used to indicate a scope, the content of a token list, box
+or macro body, etc. \NC \NR
+\NC 2 \NC end group \NC This marks the end of a group. \NC \NR
+\NC 3 \NC math shift \NC Math starts and ends with characters
+tagged like this. Two in a row indicate display math. \NC \NR
+\NC 4 \NC alignment tab \NC Characters with this property indicate
+a next entry in an alignment. \NC \NR
+\NC 5 \NC end line \NC This one is somewhat special. As line
+endings are operating system dependent, they are normalized to
+character 13 and by default that one has this category code. \NC
+\NR
+\NC 6 \NC parameter \NC Macro parameters start with a character
+with this category code. Such characters are also used in
+alignment specifications. In nested definitions, multiple of them
+in a row are used. \NC \NR
+\NC 7 \NC superscript \NC Tagged like this, a character signals
+that the next token (or group) is to be superscripted. Two such
+characters in a row will make the parser treat the following
+character or lowercase hexadecimal number as specification for
+a replacement character. \NC \NR
+\NC 8 \NC subscript \NC Codes as such, a character signals that
+the next token (or group) is to be subscripted. \NC \NR
+\NC 9 \NC ignored \NC When a character has this category code it
+is simply ignored. \NC \NR
+\NC 10 \NC space \NC This one is also special. Any character tagged
+as such is converted to the \ASCII\ space character with code 32.
+\NC \NR
+\NC 11 \NC letter \NC Normally this are the characters that make op
+sequences with a meaning like words. Letters are special in the sense that
+macro names can only be made of letters. The hyphenation machinery will
+normally only deal with letters. \NC \NR
+\NC 12 \NC other \NC Examples of other characters are punctuation and
+special symbols. \NC \NR
+\NC 13 \NC active \NC This makes a character into a macro. Of course
+it needs to get a meaning in order not to trigger an error. \NC \NR
+\NC 14 \NC comment \NC All characters on the same line after comment
+characters are ignored. \NC \NR
+\NC 15 \NC invalid \NC An error message is issued when an invalid
+character is seen. This catcode is probably not assigned very
+often. \NC \NR
+\stoptabulate
+
+So, there is a lot to tell about these codes. We will not discuss the input
+parser here, but it is good to know that the following happens.
+
+\startitemize[packed]
+\startitem
+    The engine reads lines, and normalizes cariage return
+    and linefeed sequences.
+\stopitem
+\startitem
+    Each line gets a character with number \type {\endlinechar} appended.
+    Normally this is a character with code 13. In \LUATEX\ a value of $-1$ will
+    disable this automatism.
+\stopitem
+\startitem
+    Normally spaces (characters with the space property) at the end of a line are
+    discarded.
+\stopitem
+\startitem
+    Sequences like \type {^^A} are converted to characters with numbers depending
+    on the position in \ASCII\ vector: \type {^^@} is zero, \type {^^A} is one,
+    etc.
+\stopitem
+\startitem
+    Sequences like \type {^^1f} are converted to characters with a number similar
+    to the (lowercase) hexadecimal part.
+\stopitem
+\stopitemize
+
+Hopefully this is enough background information to get through the following
+sections so let's stick to a simple example:
+
+\starttyping
+\def\test#1{$x_{#1}$}
+\stoptyping
+
+Here there are two control sequences, starting with a backslash with category
+code zero. Then comes an category~6 character that indicates a parameter that is
+referenced later on. The outer curly braces encapsulate the definition and the
+inner two braces mark the argument to a subscript, which itself is indicated by
+an underscore with category code~8. The start and end of mathmode is indicated
+with a dollar sign that is tagged as math shift (category code~3). The character
+\type {x} is just a letter.
+
+Given the above description, how do we deal with catcodes and newlines at the
+\LUA\ end? Catcodes are easy: we can print back to \TEX\ using a specific catcode
+regime (later we will see a few of those regimes). As character~13 is used as
+default at the \TEX\ end, we should also use it at the \LUA\ end, i.e.\ we should
+use \type {\r} as line terminator (\type {\endlinechar}). On the other hand, we
+have to use \type {\n} (character 10, \type {\newlinechar}) for printing to the
+terminal, log file, of \TEX\ output handles, although in \CONTEXT\ all that
+happens via \LUA\ anyway, so we don't bother too much about it here.
+
+There is a pitfall. As \TEX\ reads lines, it depends on the file system to
+provide them: it fetches lines or whatever represents the same on block devices.
+In \LUATEX\ the implementation is similar: if you plug in a reader callback, it
+has to provide a function that returns a line. Passing two lines does not work
+out as expected as \TEX\ discards anything following the line separator (cr, lf
+or crlf) and then appends a normalized endline character (in our case
+character~13). At least, this is what \TEX\ does naturally. So, in callbacks you
+can best feed line by line without any of those characters.
+
+When you print something from \LUA\ to \TEX\ the situation is slightly different:
+
+\startbuffer
+\startluacode
+tex.print("line 1\r line 2")
+tex.print("line 3\n line 4")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This is what we get:
+
+\startpacked\getbuffer\stoppacked
+
+The explicit \type {\endlinechar} (\type {\r}) terminates the line and the rest
+gets discarded. However, a \type {\n} by default has category code~12 (other) and
+is turned into a space and successive spaces are (normally) ignored, which is why
+we get the third and fourth line separated by a space.
+
+Things get real hairy when we do the following:
+
+\startbuffer
+\startluacode
+tex.print("\\bgroup")
+tex.print("\\obeylines")
+tex.print("line 1\r line 2")
+tex.print("line 3\n line 4")
+tex.print("\\egroup")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Now we get this (the \type {tex.print} function appends an endline character
+itself):
+
+\startpacked\getbuffer\stoppacked
+
+By making the endline character active and equivalent to \type {\par} \TEX\
+nicely scans on and we get the second line as well. Now, if you're still with us,
+you're ready for the next section.
+
+\stopsection
+
+\startsection[title={Plain \TEX}]
+
+In the \TEX\ engine, some characters already have a special meaning. This is
+needed because otherwise we cannot use the macro language to set up the format.
+This is hard|-|coded so the next code is not really used.
+
+\starttyping
+\catcode `\^^@ =  9  % ascii null is ignored
+\catcode `\^^M =  5  % ascii return is end-line
+\catcode `\\   =  0  % backslash is TeX escape character
+\catcode `\%   = 14  % percent sign is comment character
+\catcode `\    = 10  % ascii space is blank space
+\catcode `\^^? = 15  % ascii delete is invalid
+\stoptyping
+
+There is no real reason for setting up the null and delete character but maybe in
+those days the input could contain them. The regular upper- and lowercase
+characters are initialized to be letters with catcode~11. All other characters
+get category code~12 (other).
+
+The plain \TEX\ format starts with setting up some characters that get a special
+meaning.
+
+\starttyping
+\catcode `\{   =  1 % left brace is begin-group character
+\catcode `\}   =  2 % right brace is end-group character
+\catcode `\$   =  3 % dollar sign is math shift
+\catcode `\&   =  4 % ampersand is alignment tab
+\catcode `\#   =  6 % hash mark is macro parameter character
+\catcode `\^   =  7 \catcode`\^^K=7 % circumflex and uparrow
+                                    % are for superscripts
+\catcode `\_   =  8 \catcode`\^^A=8 % underline and downarrow
+                                    % are for subscripts
+\catcode `\^^I = 10 % ascii tab is a blank space
+\catcode `\~   = 13 % tilde is active
+\stoptyping
+
+The fact that this happens in the format file indicates that it is not by design
+that for instance curly braces are used for grouping, or the hash for indicating
+arguments. Even math could have been set up differently. Nevertheless, all macro
+packages have adopted these conventions so they could as well have been
+hard|-|coded presets.
+
+Keep in mind that nothing prevents us to define more characters this way, so we
+could make square brackets into group characters as well. I wonder how many
+people have used the two additional special characters that can be used for
+super- and subscripts. The comment indicates that it is meant for a special
+keyboard.
+
+One way to make sure that a macro will not be overloaded is to use characters in
+it's name that are letters when defining the macro but make sure that they are
+others when the user inputs text.
+
+\starttyping
+\catcode `@ = 11
+\stoptyping
+
+Again, the fact that plain \TEX\ uses the commercial at sign has set a standard.
+After all, at that time this symbol was not as popular as it is nowadays.
+
+Further on in the format some more catcode magic happens. For instance this:
+
+\starttyping
+\catcode `\^^L = 13 \outer\def^^L{\par} % ascii form-feed is "\outer\par"
+\stoptyping
+
+So, in your input a formfeed is equivalent to an empty line which makes sense,
+although later we will see that in \CONTEXT\ we do it differently. As the tilde
+was already active it also gets defined:
+
+\starttyping \def~{\penalty10000\ } % tie \stoptyping
+
+Again, this convention is adopted and therefore a sort of standard. Nowadays we
+have special \UNICODE\ characters for this, but as they don't have a
+visualization editing is somewhat cumbersome.
+
+The change in catcode of the newline character \type {^^M} is done locally, for
+instance in \type {\obeylines}. Keep in mind that this is the character that
+\TEX\ appends to the end of an input line. The space is made active when spaces
+are to be obeyed.
+
+A few very special cases are the following.
+
+\starttyping
+\mathcode `\^^Z = "8000 % \ne
+\mathcode `\    = "8000 % \space
+\mathcode `\'   = "8000 % ^\prime
+\mathcode `\_   = "8000 % \_
+\stoptyping
+
+This flags those characters as being special in mathmode. Normally when you do
+something like this:
+
+\starttyping
+\def\test#1{$#1$} \test{x_2} \test{x''}
+\stoptyping
+
+The catcodes that are set when passing the argument to \type {\test} are frozen
+when they end up in the body of the macro. This means that when \type {'} is
+other it will be other when the math list is built. However, in math mode, plain
+\TEX\ wants to turn that character into a prime and even in a double one when
+there are two in a row. The special value \type {"8000} tells the math machinery
+that when it has an active meaning, that one will be triggered. And indeed, the
+plain format defined these active characters, but in a special way, sort of:
+
+\starttyping
+{ \catcode`\' = 13 \gdef'{....} }
+\stoptyping
+
+So, when active it has a meaning, and it happens to be only treated as active
+when in math mode.
+
+Quite some other math codes are set as well, like:
+
+\starttyping
+\mathcode`\^^@ = "2201 % \cdot
+\mathcode`\^^A = "3223 % \downarrow
+\mathcode`\^^B = "010B % \alpha
+\mathcode`\^^C = "010C % \beta
+\stoptyping
+
+In Appendix~C of The \TeX book Don Knuth explains the rationale behind this
+choice: he had a keyboard that has these shortcuts. As a consequence, one of the
+math font encodings also has that layout. It must have been a pretty classified
+keyboard as I could not find a picture on the internet. One can probably assemble
+such a keyboard from one of those keyboard that come with no imprint. Anyhow, Don

+\startsection[title={How about \CONTEXT}]
+
+In \CONTEXT\ we've always used several catcode regimes and switching between them
+was a massive operation. Think of a different regime when defining macros,
+inputting text, typesetting verbatim, processing \XML, etc. When \LUATEX\
+introduced catcode tables, the existing mechanisms were rewritten to take
+advantage of this. This is the standard table for input as of December 2010.
+
+\starttyping
+\startcatcodetable \ctxcatcodes
+  \catcode \tabasciicode        \spacecatcode
+  \catcode \endoflineasciicode  \endoflinecatcode

+  \catcode \tildeasciicode      \activecatcode
+  \catcode \barasciicode        \activecatcode
+\stopcatcodetable
+\stoptyping
+
+Because the meaning of active characters can differ per table there is a related
+mechanism for switching those meanings. A careful reader might notice that the
+formfeed character is just a newline. If present at all, it often sits on its own
+line, so effectively it then behaves as in plain \TEX: triggering a new
+paragraph. Otherwise it becomes just a space in the running text.
+
+In addition to the active tilde we also have an active bar. This is actually one
+of the oldest features: we use bars for signaling special breakpoints, something
+that is really needed in Dutch (education), where we have many compound words.
+Just to show a few applications:
+
+\starttyping
+firstpart||secondpart  this|(|orthat)  one|+|two|+|three
+\stoptyping
+
+In \MKIV\ we have another way of dealing with this. There you can enable a
+special parser that deals with it at another level, the node list.
+
+\starttyping
+\setbreakpoints[compound]
+\stoptyping
+
+When \TEX ies discuss catcodes some can get quite upset, probably because they
+spend some time fighting their side effects. Personally I like the concept. They
+can be a pain to deal with but also can be fun. For instance, support of \XML\ in
+\CONTEXT\ \MKII\ was made possible by using active \type {<} and \type {&}.
+
+When dealing with all kind of inputs the fact that characters have special
+meanings can get in the way. One can argue that once a few have a special
+meaning, it does not matter that some others have. Most complaints from users
+concern \type {$}, \type {&} and \type {_}. When for symmetry we add \type {^} it
+is clear that these characters relate to math.
+
+Getting away from the \type {$} can only happen when users are willing to use for
+instance \type {\m{x}} instead of \type {$x$}. The \type {&} is an easy one
+because in \CONTEXT\ we have always discouraged its use in tables and math
+alignments. Using (short) commands is a bit more keying but also provides more
+control. That leaves the \type {_} and \type {^} and there is a nice solution for
+this: the special math tagging discussed in the previous section.
+
+For quite a while \CONTEXT\ provides two commands that makes it possible to use
+\type {&}, \type {_} and \type {^} as characters with only a special meaning
+inside math mode. The command
+
+\starttyping
+\nonknuthmode
+\stoptyping
+
+turns on this feature. The counterpart of this command is
+
+\starttyping
+\donknuthmode
+\stoptyping
+
+One step further goes the command:
+
+\starttyping
+\asciimode
+\stoptyping
+
+This only leave the backslash and curly braces a special meaning.

+
+So, even the percentage character being a comment starter is no longer there. At
+this time it's still being discussed where we draw the line. For instance, using
+the following setup renders puts \TEX\ out of action, and we happily use it deep
+down in \CONTEXT\ to deal with verbatim.

+
+\startsection[title={Where are we heading?}]
+
+When defining macros, in \CONTEXT\ we not only use the \type {@} to provide some
+protection against overloading, but also the \type {?} and \type {!}. There is of
+course some freedom in how to use them but there are a few rules, like:
+
+\starttyping
+\c!width         % interface neutral key
+\v!yes           % interface neutral value
+\s!default       % system constant
+\e!start         % interface specific command name snippet
+\!!depth         % width as keyword to primitive
+\!!stringa       % scratch macro
+\??ab            % namespace
+\@@abwidth       % namespace-key combination
+\stoptyping
+
+There are some more but this demonstrates the principle. When defining macros
+that use these, you need to push and pop the current catcode regime
+
+\starttyping
+\pushcatcodes
+\catcodetable \prtcatcodes
+....
+\popcatcodes
+\stoptyping
+
+or more convenient:
+
+\starttyping
+\unprotect
+....
+\protect
+\stoptyping
+
+Recently we introduced named parameters in \CONTEXT\ and files that are coded
+that way are tagged as \MKVI. Because we nowadays are less concerned about
+performance, some of the commands that define the user interface have been
+rewritten. At the cost of a bit more runtime we move towards a somewhat cleaner
+inheritance model that uses less memory. As a side effect module writers can
+define the interface to functionality with a few commands; think of defining
+instances with inheritance, setting up instances, accessing parameters etc. It
+sounds more impressive than it is in practice but the reason for mentioning it
+here is that this opportunity is also used to provide module writers an
+additional protected character: \type {_}.
+
+\starttyping
+\def\do_this_or_that#variable#index%
+  {$#variable_{#index}$}
+
+\def\thisorthat#variable#index%
+  {(\do_this_or_that{#variable}{#index})}
+\stoptyping
+
+Of course in the user macros we don't use the \type {_} if only because we want
+that character to show up as it is meant.

+\stopcatcodetable
+\stoptyping
+
+This table is currently used when defining core macros and modules. A rather
+special case is the circumflex. It still has a superscript related catcode, and
+this is only because the circumflex has an additional special meaning
+
+Instead of the symbolic names in the previous blob of code we could have
+indicated characters numbers as follows:
+
+\starttyping
+\catcode `\^^I \spacecatcode
+\stoptyping
+
+However, if at some point we decide to treat the circumflex similar as the
+underscore, i.e.\ give it a letter catcode, then we should not use this double
+circumflex method. In fact, the code base does not do that any longer, so we can
+decide on that any moment. If for some reason the double circumflex method is
+needed, for instance when defining macros like \type {\obeylines}, one can do
+this:
+
+\starttyping
+\bgroup
+  \permitcircumflexescape
+  \catcode \endoflineasciicode \activecatcode
+  \gdef\obeylines%
+    {\catcode\endoflineasciicode\activecatcode%
+     \def^^M{\par}}
+\egroup
+\stoptyping
+
+However, in the case of a newline one can also do this:
+
+\starttyping
+\bgroup
+  \catcode \endoflineasciicode \activecatcode
+  \gdef\obeylines%
+    {\catcode\endoflineasciicode\activecatcode%
+     \def
+       {\par}}
+\egroup
+\stoptyping
+
+Or just:
+
+\starttyping
+\def\obeylines{\defineactivecharacter 13 {\par}}
+\stoptyping
+
+In \CONTEXT\ we have the following variant, which is faster
+than the previous one.
+
+\starttyping
+\def\obeylines
+  {\catcode\endoflineasciicode\activecatcode
+   \expandafter\def\activeendoflinecode{\obeyedline}}
+\stoptyping
+
+So there are not circumflexes used at all. Also, we only need to change the
+meaning of \type {\obeyedline} to give this macro another effect.
+
+All this means that we are upgrading catcode tables, we also consider making
+\type {\nonknuthmode} the default, i.e.\ move the initialization to the catcode
+vectors. Interesting is that we could have done that long ago, as the mentioned
+\type {"8000} trickery has proven to be quite robust. In fact, in math mode we're
+still pretty much in knuth mode anyway.
+
+There is one pitfall. Take this:
+
+\starttyping
+\def\test{$\something_2$} % \something_
+\def\test{$\something_x$} % \something_x
+\stoptyping
+
+When we are in unprotected mode, the underscore is part of the macro name, and
+will not trigger a subscript. The solution is simple:
+
+\starttyping
+\def\test{$\something _2$}
+\def\test{$\something _x$}
+\stoptyping
+
+In the rather large \CONTEXT\ code base there were only a few spots where we had
+to add a space. When moving on to \MKIV\ we have the freedom to introduce such
+changes, although we don't want to break compatibility too much and only for the
+good. We expect this all to settle down in 2011. No matter what we decide upon,
+some characters will always have a special meaning. So in fact we always stay in
+some sort of donknuthmode, which is what \TEX\ is all about.

+\startchapter[title={Updating the code base}]
+
+\startsection [title={Introduction}]
+
+After much experimenting with new code in \MKIV\ a new stage in \CONTEXT\
+development was entered in the last quarter of 2011. This was triggered by
+several more or less independent developments. I will discuss some of them here
+since they are a nice illustration of how \CONTEXT\ evolves. This chapter was
+published in TugBoat 103; thanks to Karl Berry and Barbara Beeton for making it
+better.
+
+\stopsection
+
+\startsection [title={Interfacing}]
+
+Wolfgang Schuster, Aditya Mahajan and I were experimenting with an abstraction
+layer for module writers. In fact this layer itself was a variant of some new
+mechanisms used in the \MKIV\ structure related code. That code was among the
+first to be adapted as it is accompanied by much \LUA\ code and has been
+performing rather well for some years now.
+
+In \CONTEXT\ most of the user interface is rather similar and module writers are
+supposed to follow the same route as the core of \CONTEXT. For those who have
+looked in the source the following code might look familiar:
+
+\starttyping
+\unexpanded\def\mysetupcommand
+  {\dosingleempty\domysetupcommand}
+
+\def\domysetupcommand[#1]%
+  {..........
+   \getparameters[\??my][#1]%
+   ..........
+   ..........}
+\stoptyping
+
+This implements the command \type {\mysetupcommand} that is used as
+follows:
+
+\starttyping
+\mysetupcommand[color=red,style=bold,...]
+\stoptyping
+
+The above definition uses three rather low|-|level interfacing commands. The
+\type {\unexpanded} makes sure that the command does not expand in unexpected
+ways in cases where expansion is less desirable. (Aside: The \CONTEXT\ \type
+{\unexpanded} prefix has a long history and originally resulted in the indirect
+definition of a macro. That way the macro could be part of testing (expanded)
+equivalence. When \ETEX\ functionality showed up we could use \type {\protected}
+but we stuck to the name \type {\unexpanded}. So, currently \CONTEXT's \type
+{\unexpanded} is equivalent to \ETEX's \type {\protected}. Furthermore, in
+\CONTEXT\ \type {\expanded} is not the same as the \ETEX\ primitive. In order to
+use the primitives you need to use their \type {\normal...} synonyms.) The \type
+{\dosingleempty} makes sure that one argument gets seen by injecting a dummy when
+needed. At some point the \type {\getparameters} command will store the values of
+keys in a namespace that is determined by \type {\??my}. The namespace used here
+is actually one of the internal namespaces which can be deduced from the double
+question marks. Module namespaces have four question marks.
+
+There is some magic involved in storing the values. For instance, keys are
+translated from the interface language into the internal language which happens
+to be English. This translation is needed because a new command is generated:
+
+\starttyping
+\def\@@mycolor{red}
+\def\@@mystyle{bold}
+\stoptyping
+
+and such a command can be used internally because in so|-|called unprotected mode
+\type {@?!} are valid in names. The Dutch equivalent is:
+
+\starttyping
+\mijnsetupcommando[kleur=rood,letter=vet]
+\stoptyping
+
+and here the \type {kleur} has to be converted into \type {color} before the
+macro is constructed. Of course values themselves can stay as they are as long as
+checking them uses the internal symbolic names that have the language specific
+meaning.
+
+\starttyping
+\c!style{color}
+\k!style{kleur}
+\v!bold {vet}
+\stoptyping
+
+Internally assignments are done with the \type {\c!} variant, translation of the
+key is done using the \type {\k!} alternative and values are prefixed by \type
+{\v!}.
+
+It will be clear that for the English user interface no translation is needed and
+as a result that interface is somewhat faster. There we only need
+
+\starttyping
+\c!style{color}
+\v!bold {bold}
+\stoptyping
+
+Users never see these prefixed versions, unless they want to define an
+internationalized style, in which case the form
+
+\starttyping
+\mysetupcommand[\c!style=\v!bold]
+\stoptyping
+
+has to be used, as it will adapt itself to the user interface. This leaves the
+\type {\??my} that in fact expands to \type {\@@my}. This is the namespace prefix.
+
+Is this the whole story? Of course it isn't, as in \CONTEXT\ we often have a
+generic instance from which we can clone specific alternatives; in practice, the
+\type {\@@mycolor} variant is used in a few cases only. In that case a setup
+command can look like:
+
+\starttyping
+\mysetupcommand[myinstance][style=bold]
+\stoptyping
+
+And access to the parameters is done with:
+
+\starttyping
+\getvalue{\??my myinstance\c!color}
+\stoptyping
+
+So far the description holds for \MKII\ as well as \MKIV, but in \MKIV\ we are
+moving to a variant of this. At the cost of a bit more runtime and helper macros,
+we can get cleaner low|-|level code. The magic word here is \type
+{commandhandler}. At some point the new \MKIV\ code started using an extra
+abstraction layer, but the code needed looked rather repetitive despite subtle
+differences. Then Wolfgang suggested that we should wrap part of that
+functionality in a definition macro that could be used to define module setup and
+definition code in one go, thereby providing a level of abstraction that hides
+some nasty details. The main reason why code could look cleaner is that the
+experimental core code provided a nicer inheritance model for derived instances
+and Wolfgang's letter module uses that extensively. After doing some performance
+tests with the code we decided that indeed such an initializer made sense. Of
+course, after that we played with it, some more tricks were added, and eventually
+I decided to replace the similar code in the core as well, that is: use the
+installer instead of defining helpers locally.
+
+So, how does one install a new setup mechanism? We stick to the core code and
+leave modules aside for the moment.
+
+\starttyping
+\definesystemvariable{my}
+
+\installcommandhandler \??my {whatever} \??my
+\stoptyping
+
+After this command we have available some new helper commands of which only a few
+are mentioned here (after all, this mechanism is still somewhat experimental):
+
+\starttyping
+\setupwhatever[key=value]
+\setupwhatever[instance][key=value]
+\stoptyping
+
+Now a value is fetched using a helper:
+
+\starttyping
+\namedwhateverparameter{instance}{key}
+\stoptyping
+
+However, more interesting is this one:
+
+\starttyping
+\whateverparameter{key}
+\stoptyping
+
+For this to work, we need to set the instance:
+
+\starttyping
+\def\currentwhatever{instance}
+\stoptyping
+
+Such a current state macro already was used in many places, so it fits into the
+existing code quite well. In addition to \type {\setupwhatever} and friends,
+another command becomes available:
+
+\starttyping
+\definewhatever[instance]
+\definewhatever[instance][key=value]
+\stoptyping
+
+Again, this is not so much a revolution as we can define such a command easily
+with helpers, but it pairs nicely with the setup command. One of the goodies is
+that it provides the following feature for free:
+
+\starttyping
+\definewhatever[instance][otherinstance]
+\definewhatever[instance][otherinstance][key=value]
+\stoptyping
+
+In some cases this creates more overhead than needed because not all commands
+have instances. On the other hand, some commands that didn't have instances yet,
+now suddenly have them. For cases where this is not needed, we provide simple
+variants of commandhandlers.
+
+Additional commands can be hooked into a setup or definition so that for instance
+the current situation can be updated or extra commands can be defined for this
+instance, such as \type {\start...} and \type {\stop...} commands.
+
+It should be stressed that the installer itself is not that special in the sense
+that we could do without it, but it saves some coding. More important is that we
+no longer have the \type {@@} prefixed containers but use \type
+{\whateverparameter} commands instead. This is definitely slower than the direct
+macro, but as we often deal with instances, it's not that much slower than \type
+{\getvalue} and critical components are rather well speed|-|optimized anyway.
+
+There is, however, a slowdown due to the way inheritance is implemented. That is
+how this started out: using a different (but mostly compatible) inheritance
+model. In the \MKII\ approach (which is okay in itself) inheritance happens by
+letting values point to the parent value. In the new model we have a more dynamic
+chain. It saves us macros but can expand quite wildly depending on the depth of
+inheritance. For instance, in sectioning there can easily be five or more levels
+of inheritance. So, there we get slower processing. The same is true for \type
+{\framed} which is a rather critical command, but there it is nicely compensated
+by less copying. My personal impression is that due to the way \CONTEXT\ is set
+up, the new mechanism is actually more efficient on an average job. Also, because
+many constructs also depend on the \type {\framed} command, that one can easily
+be part of the chain, which again speeds up a bit. In any case, the new
+mechanisms use much less hash space.
+
+Some mechanisms still look too complex, especially when they hook into others.
+Multiple inheritance is not trivial to deal with, not only because the meaning of
+keys can clash, but also because supporting it would demand quite complex fully
+expandable resolvers. So for the moment we stay away from it. In case you wonder
+why we cannot delegate more to \LUA: it's close to impossible to deal with \TEX's
+grouping in efficient ways at the \LUA\ end, and without grouping available \TEX\
+becomes less useful.
+
+Back to the namespace. We already had a special one for modules but after many
+years of \CONTEXT\ development, we started to run out of two character
+combinations and many of them had no relation to what name they spaced. As the
+code base is being overhauled anyway, it makes sense to also provide a new core
+namespace mechanism. Again, this is nothing revolutionary but it reads much more
+nicely.
+
+\starttyping
+\installcorenamespace {whatever}
+
+\installcommandhandler \??whatever {whatever} \??whatever
+\stoptyping
+
+This time deep down no \type {@@} is used, but rather something more obscure. In
+any case, no one will use the meaning of the namespace variables, as all access
+to parameters happens indirectly. And of course there is no speed penalty
+involved; in fact, we are more efficient. One reason is that we often used the
+prefix as follows:
+
+\starttyping
+\setvalue{\??my:option:bla}{foo}
+\stoptyping
+
+and now we just say:
+
+\starttyping
+\installcorenamespace {whateveroption}
+
+\setvalue{\??whateveroption bla}{foo}
+\stoptyping
+
+The commandhandler does such assignments slightly differently as it has to prevent
+clashes between instances and keywords. A nice example of such a clash is this:
+
+\starttyping
+\setvalue{\??whateveroption sectionnumber}{yes}
+\stoptyping
+
+In sectioning we have instances named \type {section}, but we also have keys
+named \type {number} and \type {sectionnumber}. So, we end up with
+something like this:
+
+\starttyping
+\setvalue{\??whateveroption section:sectionnumber}{yes}
+\setvalue{\??whateveroption section:number}{yes}
+\setvalue{\??whateveroption :number}{yes}
+\stoptyping
+
+When I decided to replace code similar to that generated by the installer a new
+rewrite stage was entered. Therefore one reason for explaining this here is that
+in the process of adapting the core code instabilities are introduced and as most
+users use the beta version of \MKIV, some tolerance and flexibility is needed and
+it might help to know why something suddenly fails.
+
+In itself using the commandhandler is not that problematic, but wherever I decide
+to use it, I also clean up the related code and that is where the typos creep in.
+Fortunately Wolfgang keeps an eye on the changes so problems that users report on
+the mailing lists are nailed down relatively fast. Anyway, the rewrite itself is
+triggered by another event but that one is discussed in the next section.
+
+We don't backport (low|-|level) improvements and speedups to \MKII, because for
+what we need \TEX\ for, we consider \PDFTEX\ and \XETEX\ rather obsolete. Recent
+tests show that at the moment of this writing a \LUATEX\ \MKIV\ run is often
+faster than a comparable \PDFTEX\ \MKII\ run (using \UTF-8 and complex font
+setups). When compared to a \XETEX\ \MKII\ run, a \LUATEX\ \MKIV\ run is often
+faster, but it's hard to compare, as we have advanced functionality in \MKIV\
+that is not (or differently) available in \MKII.
+
+\stopsection
+
+\startsection [title={Lexing}]
+
+The editor that I use, called \SCITE, has recently been extended with an extra
+external lexer module that makes more advanced syntax highlighting possible,
+using the \LUA\ \LPEG\ library. It is no secret that the user interface of
+\CONTEXT\ is also determined by the way structure, definitions and setups can be
+highlighted in an editor. \footnote {It all started with \type {wdt}, \type
+{texedit} and \type {texwork}, editors and environments written by myself in
+\MODULA2 and later in \PERL\ Tk, but that was in a previous century.} When I
+changed to \SCITE\ I made sure that we had proper highlighting there.
+
+At \PRAGMA\ one of the leading principles has always been: if the document source
+looks bad, mistakes are more easily made and the rendering will also be affected.
+Or phrased differently: if we cannot make the source look nice, the content is
+probably not structured that well either. The same is true for \TEX\ source,
+although to a large extent there one must deal with the specific properties of
+the language.
+
+So, syntax highlighting, or more impressively: lexing, has always been part of
+the development of \CONTEXT\ and for instance the pretty printers of verbatim
+provide similar features. For a long time we assumed line|-|based lexing, mostly
+for reasons of speed. And surprisingly, that works out quite well with \TEX. We
+used a simple color scheme suitable for everyday usage, with not too intrusive
+coloring. Of course we made sure that we had runtime spell checking integrated,
+and that the different user interfaces were served well.
+
+But then came the \LPEG\ lexer. Suddenly we could do much more advanced
+highlighting. Once I started playing with it, a new color scheme was set up and
+more sophisticated lexing was applied. Just to mention a few properties:
+
+\startitemize[packed]
+\startitem
+    We distinguish between several classes of macro names: primitives, helpers,
+    interfacing, and user macros.
+\stopitem
+\startitem
+    In addition we highlight constant values and special registers differently.
+\stopitem
+\startitem
+    Conditional constructs can be recognized and are treated as in any
+    regular language (keep in mind that users can define their own).
+\stopitem
+\startitem
+    Embedded \METAPOST\ code is lexed independently using a lexer that knows the
+    language's primitives, helpers, user macros, constants and of course specific
+    syntax and drawing operators. Related commands at the \TEX\ end (for defining
+    and processing graphics) are also dealt with.
+\stopitem
+\startitem
+    Embedded \LUA\ is lexed independently using a lexer that not only deals with the

+    Real|-|time spell checking is part of the deal and can optionally be turned on.

+\stopitem
+\stopitemize
+
+Of course we also made lexers for \METAPOST, \LUA, \XML, \PDF\ and text documents
+so that we have a consistent look and feel.
+
+When writing the new lexer code, and testing it on sources, I automatically
+started adapting the source to the new lexing where possible. Actually, as
+cleaning up code is somewhat boring, the new lexer is adding some fun to it. I'm
+not so sure if I would have started a similar overhaul so easily otherwise,
+especially because the rewrite now also includes speedup and cleanup. At least it
+helps to recognize less desirable left|-|overs of \MKII\ code.
+
+\stopsection
+
+\startsection [title={Hiding}]
+
+It is interesting to notice that users seldom define commands that clash with low
+level commands. This is of course a side effect of the fact that one seldom needs
+to define a command, but nevertheless. Low|-|level commands were protected by
+prefixing them by one or more (combinations of) \type {do}, \type {re} and \type
+{no}'s. This habit is a direct effect of the early days of writing macros. For
+\TEX\ it does not matter how long a name is, as internally it becomes a pointer
+anyway, but memory consumption of editors, loading time of a format, string space
+and similar factors determined the way one codes in \TEX\ for quite a while.
+Nowadays there are hardly any limits and the stress that \CONTEXT\ puts on the
+\TEX\ engine is even less than in \MKII\ as we delegate many tasks to \LUA.
+Memory comes cheap, editors can deal with large amount of data (keep in mind that
+the larger the file gets, the more lexing power can be needed), and screens are
+wide enough not to lose part of long names in the edges.
+
+Another development has been that in \LUATEX\ we have lots of registers so that
+we no longer have to share temporary variables and such. The rewrite is a good
+moment to get rid of that restriction.
+
+This all means that at some point it was decided to start using longer command
+names internally and permit \type {_} in names. As I was never a fan of using
+\type {@} for this, underscore made sense. We have been discussing the use of
+colons, which is also nice, but has the disadvantage that colons are also used in
+the source, for instance to create a sub|-|namespace. When we have replaced all
+old namespaces, colons might show up in command names, so another renaming
+roundup can happen.
+
+One reason for mentioning this is that users get to see these names as part of
+error messages. An example of a name is:
+
+\starttyping
+\page_layouts_this_or_that
+\stoptyping
+
+The first part of the name is the category of macros and in most cases is the
+same as the first part of the filename. The second part is a namespace. The rest
+of the name can differ but we're approaching some consistency in this.
+
+In addition we have prefixed names, where prefixes are used as consistently as
+possible:
+
+\starttabulate[|l|l|]
+\NC \type {t_} \NC token register \NC \NR
+\NC \type {d_} \NC dimension register \NC \NR
+\NC \type {s_} \NC skip register \NC \NR
+\NC \type {u_} \NC muskip register \NC \NR
+\NC \type {c_} \NC counter register, constant or conditional \NC \NR
+\NC \type {m_} \NC (temporary) macro \NC \NR
+\NC \type {p_} \NC (temporary) parameter expansion (value of key)\NC \NR
+\NC \type {f_} \NC fractions \NC \NR
+\stoptabulate
+
+This is not that different from other prefixing in \CONTEXT\ apart from the fact
+that from now on those variables (registers) are no longer accessible in a
+regular run. We might decide on another scheme but renaming can easily be
+scripted. In the process some of the old prefixes are being removed. The main
+reason for changing to this naming scheme is that it is more convenient to grep
+for them.
+
+In the process most traditional \type {\if}s get replaced by \quote
+{conditionals}.  The same is true for \type {\chardef}s that store states;
+these become \quote {constants}.
+
+\stopsection
+
+\startsection[title=Status]
+
+We always try to keep the user interface constant, so most functionality and
+control stays stable. However, now that most users use \MKIV, commands that no
+longer make sense are removed. An interesting observation is that some users
+report that low|-|level macros or registers are no longer accessible. Fortunately
+that is no big deal as we point them to the official ways to deal with matters.
+It is also a good opportunity for users to clean up accumulated hackery.
+
+The systematic (file by file) cleanup started in the second half of 2011 and as
+of January 2012 one third of the core (\TEX) modules have to be cleaned up and
+the planning is to get most of that done as soon as possible. However, some
+modules will be rewritten (or replaced) and that takes more time. In any case we
+hope that rather soon most of the code is stable enough that we can start working
+on new mechanisms and features. Before that a cleanup of the \LUA\ code is
+planned.
+
+Although in many cases there are no fundamental changes in the user interface and
+functionality, I will wrap up some issues that are currently being dealt with.
+This is just a snapshot of what is happening currently and as a consequence it
+describes what users can run into due to newly introduced bugs.
+
+The core modules of \CONTEXT\ are loosely organized in groups. Over time there
+has been some reorganization and in \MKIV\ some code has been moved into new
+categories. The alphabetical order does not reflect the loading order or
+dependency tree as categories are loaded intermixed. Therefore the order below is
+somewhat arbitrary and does not express importance. Each category has multiple
+files.
+
+\startsubsubject[title={anch: anchoring and positioning}]
+
+More than a decade ago we started experimenting with position tracking. The
+ability to store positional information and use that in a second pass permits for
+instance adding backgrounds. As this code interacts nicely with (runtime)
+\METAPOST\ it has always been quite powerful and flexible on the one hand, but at
+the same time it was demanding in terms of runtime and resources. However, were
+it not for this feature, we would probably not be using \TEX\ at all, as
+backgrounds and special relative positioning are needed in nearly all our
+projects.
+
+In \MKIV\ this mechanism had already been ported to a hybrid form, but recently
+much of the code has been overhauled and its \MKII\ artifacts stripped. As a
+consequence the overhead in terms of memory probably has increased but the impact
+on runtime has been considerably reduced. It will probably take some time to
+become stable if only because the glue to \METAPOST\ has changed. There are some
+new goodies, like backgrounds behind parshapes, something that probably no one
+uses and is always somewhat tricky but it was not too hard to support. Also,
+local background support has been improved which means that it's easier to get
+them in more column-based layouts, several table mechanisms, floats and such.
+This was always possible but is now more automatic and hopefully more intuitive.
+
+\stopsubsubject
+
+\startsubsubject[title={attr: attributes}]
+
+We use attributes (properties of nodes) a lot. The framework for this had been
+laid early in \MKIV\ development, so not much has changed here. Of course the
+code gets cleaner and hopefully better as it is putting quite a load on the
+processing. Each new feature depending on attributes adds some extra overhead
+even if we make sure that mechanisms only kick in when they are used. This is due
+to the fact that attributes are linked lists and although unique lists are
+shared, they travel with each node. On the other hand, the cleanup (and
+de|-|\MKII|-|ing) of code leads to better performance so on the average no user
+will notice this.
+
+\stopsubsubject
+
+\startsubsubject[title={back: backend code generation}]
+
+This category wraps backend issues in an abstract way that is similar to the
+special drivers in \MKII. So far we have only three backends: \PDF, \XML, and
+\XHTML. Such code is always in a state of maintenance, if only because backends
+evolve.
+
+\stopsubsubject
+
+\startsubsubject[title={bibl: bibliographies}]
+
+For a while now, bibliographies have not been an add|-|on but part of the core.
+There are two variants: traditional \BIBTEX\ support derived from a module by
+Taco Hoekwater but using \MKIV\ features (the module hooks into core code), and a
+variant that delegates most work to \LUA\ by creating an in-memory \XML\ tree
+that gets manipulated. At some point I will extend the second variant. Going the
+\XML\ route also connects better with developments such as Jean|-|Michel
+Hufflen's Ml\BIBTEX.
+
+\stopsubsubject
+
+\startsubsubject[title={blob: typesetting in \LUA}]
+
+Currently we only ship a few helpers but eventually this will become a framework
+for typesetting raw text in \LUA. This might be handy for some projects that we
+have where the only input is \XML, but I'm not that sure if it will produce nice
+results and if the code will look better. On the other hand, there are some cases
+where in a regular \TEX\ run some basic typesetting in \LUA\ might make sense. Of
+course I also need an occasional pet project so this might qualify as one.
+
+\stopsubsubject
+
+\startsubsubject[title={buff: buffers and verbatim}]
+
+Traditionally buffers and verbatim have always been relatives as they share code.
+The code was among the first to be adapted to \LUATEX. There is not that much to
+gain in adapting it further. Maybe I will provide more lexers for
+pretty|-|printing some day.
+
+\stopsubsubject
+
+\startsubsubject[title={catc: catcodes}]
+
+Catcodes are a rather \TEX|-|specific feature and we have organized them in
+catcode regimes. The most important recent change has been that some of the
+characters with a special meaning in \TEX\ (like ampersand, underscore,
+superscript, etc.) are no longer special except in cases that matter. This
+somewhat incompatible change surprisingly didn't lead to many problems. Some code
+that is specific for the \MKII\ \XML\ processor has been removed as we no longer
+assume it is in \MKIV.
+
+\stopsubsubject
+
+\startsubsubject[title={char: characters}]
+
+This important category deals with characters and their properties. Already from
+the beginning of \MKIV\ character properties have been (re)organized in \LUA\
+tables and therefore much code deals with it. The code is rather stable but
+occasionally the tables are updated as they depend on developments in \UNICODE.
+In order to share as much data as possible and prevent duplicates there are
+several inheritance mechanisms in place but their overhead is negligible.
+
+\stopsubsubject
+
+\startsubsubject[title={chem: chemistry}]
+
+The external module that deals with typesetting chemistry was transformed
+into a \MKIV\ core module some time ago. Not much has changed in this department
+but some enhancements are pending.
+
+\stopsubsubject
+
+\startsubsubject[title={cldf: \CONTEXT\ \LUA\ documents}]
+
+These modules are mostly \LUA\ code and are the interface into \CONTEXT\ as well
+as providing ways to code complete documents in \LUA. This is one of those
+categories that is visited every now and then to be adapted to improvements in
+other core code or in \LUATEX. This is one of my favourite categories as it
+exposes most of \CONTEXT\ at the \LUA\ end which permits writing solutions in
+\LUA\ while still using the full power of \CONTEXT. A dedicated manual is on its
+way.
+
+\stopsubsubject
+
+\startsubsubject[title={colo: colors and transparencies}]
+
+This is rather old code, and apart from some cleanup not much has been changed
+here. Some macros that were seldom used have been removed. One issue that is
+still pending is a better interface to \METAPOST\ as it has different color
+models and we have adapted code at that end. This has a rather low priority
+because in practice it is no real problem.
+
+\stopsubsubject
+
+\startsubsubject[title={cont: runtime code}]
+
+These modules contain code that is loaded at runtime, such as filename remapping,
+patches, etc. It does not make much sense to improve these.
+
+\stopsubsubject
+
+\startsubsubject[title={core: all kinds of core code}]
+
+Housekeeping is the main target of these modules. There are still some
+typesetting|-|related components here but these will move to other categories.
+This code is cleaned up when there is a need for it. Think of managing files,
+document project structure, module loading, environments, multipass data, etc.
+
+\stopsubsubject
+
+\startsubsubject[title={data: file and data management}]
+
+This category hosts only \LUA\ code and hasn't been touched for a while. Here we
+deal with locating files, caching, accessing remote data, resources,
+environments, and the like.
+
+\stopsubsubject
+
+\startsubsubject[title={enco: encodings}]
+
+Because (font) encodings are gone, there is only one file in this category and
+that one deals with weird (composed or otherwise special) symbols. It also
+provides a few traditional \TEX\ macros that users expect to be present, for
+instance to put accents over characters.
+
+\stopsubsubject
+
+\startsubsubject[title={file: files}]
+
+There is some overlap between this category and core modules. Loading files is
+always somewhat special in \TEX\ as there is the \TEX\ directory structure to
+deal with. Sometimes you want to use files in the so|-|called tree, but other
+times you don't. This category provides some management code for (selective)
+loading of document files, modules and resources. Most of the code works with
+accompanying \LUA\ code and has not been touched for years, apart from some
+weeding and low|-|level renaming. The project structure code has mostly been
+moved to \LUA\ and this mechanism is now more restrictive in the sense that one
+cannot misuse products and components in unpredictable ways. This change permits
+better automatic loading of cross references in related documents.
+
+\stopsubsubject
+
+\startsubsubject[title={font: fonts}]
+
+Without proper font support a macro package is rather useless. Of course we do
+support the popular font formats but nowadays that's mostly delegated to \LUA\
+code. What remains at the \TEX\ end is code that loads and triggers a combination
+of fonts efficiently. Of course in the process text and math each need to get the
+proper amount of attention.
+
+There is no longer shared code between \MKII\ and \MKIV. Both already had rather
+different low|-|level solutions, but recently with \MKIV\ we went a step further.
+Of course it made sense to kick out commands that were only used for \PDFTEX\
+\TYPEONE\ and \XETEX\ \OPENTYPE\ support but more important was the decision to
+change the way design sizes are supported.
+
+In \CONTEXT\ we have basic font definition and loading code and that hasn't
+conceptually changed much over the years. In addition to that we have so-called
+bodyfont environments and these have been made a bit more powerful in recent
+\MKIV. Then there are typefaces, which are abstract combinations of fonts and
+defining them happens in typescripts. This layered approach is rather flexible,
+and was greatly needed when we had all those font encodings (to be used in all
+kinds of combinations within one document). In \MKIV, however, we already had
+fewer typescripts as font encodings are gone (also for \TYPEONE\ fonts). However,
+there remained a rather large blob of definition code dealing with Latin Modern;
+large because it comes in design sizes.
+
+As we always fall back on Latin Modern, and because we don't preload fonts, there
+is some overhead involved in resolving design size related issues and
+definitions. But, it happens that this is the only font that ships with many
+files related to different design sizes. In practice no user will change the
+defaults. So, although the regular font mechanism still provides flexible ways to
+define font file combinations per bodyfont size, resolving to the right best
+matching size now happens automatically via a so|-|called \LUA\ font goodie file
+which brings down the number of definitions considerably. The consequence is that
+\CONTEXT\ starts up faster, not only in the case of Latin Modern being used, but
+also when other designs are in play. The main reason for this is that we don't
+have to parse those large typescripts anymore, as the presets were always part of
+the core set of typescripts. At the same time loading a specific predefined set
+has been automated and optimized. Of course on a run of 30 seconds this is not
+that noticeable, but it is on a 5 second run or when testing something in the
+editor that takes less than a second. It also makes a difference in automated
+workflows; for instance at \PRAGMA\ we run unattended typesetting flows that need
+to run as fast as possible. Also, in virtual machines using network shares, the
+fewer files consulted the better.
+
+Because math support was already based on \OPENTYPE, where \CONTEXT\ turns
+\TYPEONE\ fonts into \OPENTYPE\ at runtime, nothing fundamental has changed here,
+apart from some speedups (at the cost of some extra memory). Where the overhead
+of math font switching in \MKII\ is definitely a factor, in \MKIV\ it is close to
+negligible, even if we mix regular, bold, and bidirectional math, which we have
+done for a while.
+
+The low|-|level code has been simplified a bit further by making a better
+distinction between the larger sizes (\type {a} up to \type {d}) and smaller
+sizes (\type {x} and \type {xx}). These now operate independently of each other
+(i.e.\ one can now have a smaller relative \type {x} size of a larger one). This
+goes at the cost of more resources but it is worth the effort.
+
+By splitting up the large basic font module into smaller ones, I hope that it can
+be maintained more easily although someone familiar with the older code will only
+recognize bits and pieces. This is partly due to the fact that font code is
+highly optimized.
+
+\stopsubsubject
+
+\startsubsubject[title={grph: graphic (and widget) inclusion}]
+
+Graphics inclusion is always work in progress as new formats have to be dealt
+with or users want additional conversions to be done. This code will be cleaned
+up later this year. The plug|-|in mechanisms will be extended (examples of
+existing plug|-|ins are automatic converters and barcode generation).
+
+\stopsubsubject
+
+\startsubsubject[title={hand: special font handling}]
+
+As we treat protrusion and hz as features of a font, there is not much left in
+this category apart from some fine|-|tuning. So, not much has happened here and
+eventually the left|-|overs in this category might be merged with the font
+modules.
+
+\stopsubsubject
+
+\startsubsubject[title={java: \JAVASCRIPT\ in \PDF}]
+
+This code already has been cleaned up a while ago, when moving to \MKIV, but we
+occasionally need to check and patch due to issues with \JAVASCRIPT\ engines in
+viewers.
+
+\stopsubsubject
+
+\startsubsubject[title={lang: languages and labels}]
+
+There is not much changed in this department, apart from additional labels. The
+way inheritance works in languages differs too much from other inheritance code
+so we keep what we have here. Label definitions have been moved to \LUA\ tables
+from which labels at the \TEX\ end are defined that can then be overloaded
+locally. Of course the basic interface has not changed as this is typically code
+that users will use in styles.
+
+\stopsubsubject
+
+\startsubsubject[title={luat: housekeeping}]
+
+This is mostly \LUA\ code needed to get the basic components and libraries in
+place. While the \type {data} category implements the connection to the outside
+world, this category runs on top of that and feeds the \TEX\ machinery. For
+instance conversion of \MKVI\ files happens here. These files are seldom touched
+but might need an update some time (read: prune obsolete code).
+
+\stopsubsubject
+
+\startsubsubject[title={lpdf: \PDF\ backend}]
+
+Here we implement all kinds of \PDF\ backend features. Most are abstracted via
+the backend interface. So, for instance, colors are done with a high level
+command that goes via the backend interface to the \type {lpdf} code. In fact,
+there is more such code than in (for instance) the \MKII\ special drivers, but
+readability comes at a price. This category is always work in progress as
+insights evolve and users demand more.
+
+\stopsubsubject
+
+\startsubsubject[title={lxml: \XML\ and lpath}]
+
+As this category is used by some power users we cannot change too much here,
+apart from speedups and extensions. It's also the bit of code we use frequently
+at \PRAGMA, and as we often have to deal with rather crappy \XML\ I expect to
+move some more helpers into the code. The latest greatest trickery related to
+proper typesetting can be seen in the documents made by Thomas Schmitz. I wonder
+if I'd still have fun doing our projects if I hadn't, in an early stage of \MKIV,
+written the \XML\ parser and expression parser used for filtering.
+
+\stopsubsubject
+
+\startsubsubject[title={math: mathematics}]
+
+Math deserves its own category but compared to \MKII\ there is much less code,
+thanks to \UNICODE. Since we support \TYPEONE\ as virtual \OPENTYPE\ nothing
+special is needed there (and eventually there will be proper fonts anyway). When
+rewriting code I try to stay away from hacks, which is sometimes possible by
+using \LUA\ but it comes with a slight speed penalty. Much of the \UNICODE\
+math|-|related font code is already rather old but occasionally we add new
+features. For instance, because \OPENTYPE\ has no italic correction we provide an
+alternative (mostly automated) solution.
+
+On the agenda is more structural math encoding (maybe like openmath) but tagging
+is already part of the code so we get a reasonable export. Not that someone is
+waiting for it, but it's there for those who want it. Most math|-|related
+character properties are part of the character database which gets extended on
+demand. Of course we keep \MATHML\ up|-|to|-|date because we need it in a few
+projects.
+
+We're not in a hurry here but this is something where Aditya and I have to redo
+some of the code that provides \AMS|-|like math commands (but as we have them
+configurable some work is needed to keep compatibility). In the process it's
+interesting to run into probably never|-|used code, so we just remove those
+artifacts.
+
+\stopsubsubject
+
+\startsubsubject[title={meta: metapost interfacing}]
+
+This and the next category deal with \METAPOST. This first category is quite old
+but already adapted to the new situation. Sometimes we add extra functionality
+but the last few years the situation has become rather stable with the exception
+of backgrounds, because these have been overhauled completely.
+
+\stopsubsubject
+
+\startsubsubject[title={mlib: metapost library}]
+
+Apart from some obscure macros that provide the interface between front- and
+backend this is mostly \LUA\ code that controls the embedded \METAPOST\ library.
+So, here we deal with extensions (color, shading, images, text, etc.) as well as
+runtime management because sometimes two runs are needed to get a graphic right.
+Some time ago, the \MKII|-|like extension interface was dropped in favor of one
+more natural to the library and \METAPOST~2. As this code is used on a daily
+basis it is quite well debugged and the performance is pretty good too.
+
+\stopsubsubject
+
+\startsubsubject[title={mult: multi|-|lingual user interface}]
+
+Even if most users use the English user interface, we keep the other ones around
+as they're part of the trademark. Commands, keys, constants, messages and the
+like are now managed with \LUA\ tables. Also, some of the tricky remapping code
+has been stripped because the setup definitions files are dealt with. These are
+\XML\ files that describe the user interface that get typeset and shipped with
+\CONTEXT.
+
+These files are being adapted. First of all the commandhandler code is defined
+here. As we use a new namespace model now, most of these namespaces are defined
+in the files where they are used. This is possible because they are more verbose
+so conflicts are less likely (also, some checking is done to prevent reuse).
+Originally the namespace prefixes were defined in this category but eventually
+all that code will be gone. This is a typical example where 15|-|year|-|old
+constraints are no longer an issue and better code can be used.
+
+\stopsubsubject
+
+\startsubsubject[title={node: nodes}]
+
+This is a somewhat strange category as all typeset material in \TEX\ becomes
+nodes so this deals with everything. One reason for this category is that new
+functionality often starts here and is sometimes shared between several
+mechanisms. So, for the moment we keep this category. Think of special kerning,
+insert management, low|-|level referencing (layer between user code and backend
+code) and all kinds of rule and displacement features. Some of this functionality
+is described in previously published documents.
+
+\stopsubsubject
+
+\startsubsubject[title={norm: normalize primitives}]
+
+We used to initialize the primitives here (because \LUATEX\ starts out blank).
+But after moving that code this category only has one definition left and that
+one will go too. In \MKII\ these files are still used (and actually generated by
+\MKIV).
+
+\stopsubsubject
+
+\startsubsubject[title={pack: wrapping content in packages}]
+
+This is quite an important category as in \CONTEXT\ lots of things get packed.
+The best example is \type {\framed} and this macro has been maximally optimized,
+which is not that trivial since much can be configured. The code has been adapted
+to work well with the new commandhandler code and in future versions it might use
+the commandhandler directly. This is however not that trivial because hooking a
+setup of a command into \type {\framed} can conflict with the two commands using
+keys for different matters.
+
+Layers are also in this category and they probably will be further optimized.
+Reimplementing reusable objects is on the horizon, but for that we need a more
+abstract \LUA\ interface, so that will come first. This has a low priority
+because it all works well. This category also hosts some helpers for the page
+builder but the builder itself has a separate category.
+
+\stopsubsubject
+
+\startsubsubject[title={page: pages and output routines}]
+
+Here we have an old category: output routines (trying to make a page), page
+building, page imposition and shipout, single and multi column handling, very
+special page construction, line numbering, and of course setting up pages and
+layouts. All this code is being redone stepwise and stripped of old hacks. This
+is a cumbersome process as these are core components where side effects are
+sometimes hard to trace because mechanisms (and user demands) can interfere.
+Expect some changes for the good here.
+
+\stopsubsubject
+
+\startsubsubject[title={phys: physics}]
+
+As we have a category for chemistry it made sense to have one for physics and
+here is where the unit module's code ended up. So, from now on units are
+integrated into the core. We took the opportunity to rewrite most of it from
+scratch, providing a bit more control.
+
+\stopsubsubject
+
+\startsubsubject[title={prop: properties}]
+
+The best|-|known property in \TEX\ is a font and color is a close second. Both
+have their own category of files. In \MKII\ additional properties like backend
+layers and special rendering of text were supported in this category but in
+\MKIV\ properties as a generic feature are gone and replaced by more specific
+implementations in the \type {attr} namespace. We do issue a warning when any of
+the old methods are used.
+
+\stopsubsubject
+
+\startsubsubject[title={regi: input encodings}]
+
+We still support input encoding regimes but hardly any \TEX\ code is involved
+now. Only when users demand more functionality does this code get extended. For
+instant, recently a user wanted a conversion function for going from \UTF-8 to an
+encoding that another program wanted to see.
+
+\stopsubsubject
+
+\startsubsubject[title={scrn: interactivity and widgets}]
+
+All modules in this category have been overhauled. On the one hand we lifted some
+constraints, for instance the delayed initialization of fields no longer makes
+sense as we have a more dynamic variable resolver now (which is somewhat slower
+but still acceptable). On the other hand some nice but hard to maintain features
+have been simplified (not that anyone will notice as they were rather special).
+The reason for this is that vaguely documented \PDF\ features tend to change over
+time which does not help portability. Of course there have also been some
+extensions, and it is actually less hassle (but still no fun) to deal with such
+messy backend related code in \LUA.
+
+\stopsubsubject
+
+\startsubsubject[title={scrp: script|-|specific tweaks}]
+
+These are script|-|specific \LUA\ files that help with getting better results for
+scripts like \CJK. Occasionally I look at them but how they evolve depends on
+usage. I have some very experimental files that are not in the distribution.
+
+\stopsubsubject
+
+\startsubsubject[title={sort: sorting}]
+
+As sorting is delegated to \LUA\ there is not much \TEX\ code here. The \LUA\
+code occasionally gets improved if only because users have demands. For instance,
+sorting Korean was an interesting exercise, as was dealing with multiple
+languages in one index. Because sorting can happen on a combination of \UNICODE,
+case, shape, components, etc.\ the sorting mechanism is one of the more complex
+subsystems.
+
+\stopsubsubject
+
+\startsubsubject[title={spac: spacing}]
+
+This important set of modules is responsible for vertical spacing, strut
+management, justification, grid snapping, and all else that relates to spacing
+and alignments. Already in an early stage vertical spacing was mostly delegated
+to \LUA\ so there we're only talking of cleaning up now. Although \unknown\ I'm
+still not satisfied with the vertical spacing solution because it is somewhat
+demanding and an awkward mix of \TEX\ and \LUA\ which is mostly due to the fact
+that we cannot evaluate \TEX\ code in \LUA.
+
+Horizontal spacing can be quite demanding when it comes down to configuration:
+think of a table with 1000 cells where each cell has to be set up (justification,
+tolerance, spacing, protrusion, etc.). Recently a more drastic optimization has
+been done which permits even more options but at the same time is much more
+efficient, although not in terms of memory.
+
+Other code, for instance spread|-|related status information, special spacing
+characters, interline spacing and linewise typesetting all falls into this
+category and there is probably room for improvement there. It's good to mention
+that in the process of the current cleanup hardly any \LUA\ code gets touched, so
+that's another effort.
+
+\stopsubsubject
+
+\startsubsubject[title={strc: structure}]
+
+Big things happened here but mostly at the \TEX\ end as the support code in \LUA\
+was already in place. In this category we collect all code that gets or can get
+numbered, moves around and provides visual structure. So, here we find itemize,
+descriptions, notes, sectioning, marks, block moves, etc. This means that the
+code here interacts with nearly all other mechanisms.
+
+Itemization now uses the new inheritance code instead of its own specific
+mechanism but that is not a fundamental change. More important is that code has
+been moved around, stripped, and slightly extended. For instance, we had
+introduced proper \type {\startitem} and \type {\stopitem} commands which are
+somewhat conflicting with \type {\item} where a next instance ends a previous
+one. The code is still not nice, partly due to the number of options. The code is
+a bit more efficient now but functionally the same.
+
+The sectioning code is under reconstruction as is the code that builds lists. The
+intention is to have a better pluggable model and so far it looks promising. As
+similar models will be used elsewhere we need to converge to an acceptable
+compromise. One thing is clear: users no longer need to deal with arguments but
+variables and no longer with macros but with setups. Of course providing backward
+compatibility is a bit of a pain here.
+
+The code that deals with descriptions, enumerations and notes was already done in
+a \MKIV\ way, which means that they run on top of lists as storage and use the
+generic numbering mechanism. However, they had their own inheritance support code
+and moving to the generic code was a good reason to look at them again. So, now
+we have a new hierarchy: constructs, descriptions, enumerations and notations
+where notations are hooked into the (foot)note mechanisms.
+
+These mechanisms share the rendering code but operate independently (which was
+the main challenge). I did explore the possibility of combining the code with
+lists as there are some similarities but the usual rendering is too different as
+in the interface (think of enumerations with optional local titles, multiple
+notes that get broken over pages, etc.). However, as they are also stored in
+lists, users can treat them as such and reuse the information when needed (which
+for instance is just an alternative way to deal with end notes).
+
+At some point math formula numbering (which runs on top of enumerations) might
+get its own construct base. Math will be revised when we consider the time to be
+ripe for it anyway.
+
+The reference mechanism is largely untouched as it was already doing well, but
+better support has been added for automatic cross|-|document referencing. For
+instance it is now easier to process components that make up a product and still
+get the right numbering and cross referencing in such an instance.
+
+Float numbering, placement and delaying can all differ per output routine (single
+column, multi|-|column, columnset, etc.). Some of the management has moved to
+\LUA\ but most is just a job for \TEX. The better some support mechanisms become,
+the less code we need here.
+
+Registers will get the same treatment as lists: even more user control than is
+already possible. Being a simple module this is a relatively easy task, something
+for a hot summer day. General numbering is already fine as are block moves so
+they come last. The \XML\ export and \PDF\ tagging is also controlled from this
+category.
+
+\stopsubsubject
+
+\startsubsubject[title={supp: support code}]
+
+Support modules are similar to system ones (discussed later) but on a slightly
+more abstract level. There are not that many left now so these might as well
+become system modules at some time. The most important one is the one dealing
+with boxes. The biggest change there is that we use more private registers. I'm
+still not sure what to do with the visual debugger code. The math|-|related code
+might move to the math category.
+
+\stopsubsubject
+
+\startsubsubject[title={symb: symbols}]
+
+The symbol mechanisms organizes special characters in groups. With
+\UNICODE|-|related fonts becoming more complete we hardly need this mechanism.
+However, it is still the abstraction used in converters (for instance footnote
+symbols and interactive elements). The code has been cleaned up a bit but
+generally stays as is.
+
+\stopsubsubject
+
+\startsubsubject[title={syst: tex system level code}]
+
+Here you find all kinds of low|-|level helpers. Most date from early times but
+have been improved stepwise. We tend to remove obscure helpers (unless someone
+complains loudly) and add new ones every now and then. Even if we would strip
+down \CONTEXT\ to a minimum size, these modules would still be there. Of course
+the bootstrap code is also in this category: think of allocators, predefined
+constants and such.
+
+\stopsubsubject
+
+\startsubsubject[title={tabl: tables}]
+
+The oldest table mechanism was a quite seriously patched version of \TABLE\ and
+finally the decision has been made to strip, replace and clean up that bit. So,
+we have less code, but more features, such as colored columns and more.
+
+The (in|-|stream) tabulate code is mostly unchanged but has been optimized
+(again) as it is often used. The multipass approach stayed but is somewhat more
+efficient now.
+
+The natural table code was originally meant for \XML\ processing but is quite
+popular among users. The functionality and code is frozen but benefits from
+optimizations in other areas. The reason for the freeze is that it is pretty
+complex multipass code and we don't want to break anything.
+
+As an experiment, a variant of natural tables was made. Natural tables have a
+powerful inheritance model where rows and cells (first, last, \unknown) can be
+set up as a group but that is rather costly in terms of runtime. The new table
+variant treats each column, row and cell as an instance of \type {\framed} where
+cells can be grouped arbitrarily. And, because that is somewhat extreme, these
+tables are called x|-|tables. As much of the logic has been implemented in \LUA\
+and as these tables use buffers (for storing the main body) one could imagine
+that there is some penalty involved in going between \TEX\ and \LUA\ several
+times, as we have a two, three or four pass mechanism. However, this mechanism is
+surprisingly fast compared to natural tables. The reason for writing it was not
+only speed, but also the fact that in a project we had tables of 50 pages with
+lots of spans and such that simply didn't fit into \TEX's memory any more, took
+ages to process, and could also confuse the float splitter.
+
+Line tables \unknown\ well, I will look into them when needed. They are nice in a
+special way, as they can split vertically and horizontally, but they are seldom
+used. (This table mechanism was written for a project where large quantities of
+statistical data had to be presented.)
+
+\stopsubsubject
+
+\startsubsubject[title={task: lua tasks}]
+
+Currently this is mostly a place where we collect all kinds of tasks that are
+delegated to \LUA, often hooked into callbacks. No user sees this code.
+
+\stopsubsubject
+
+\startsubsubject[title={toks: token lists}]
+
+This category has some helpers that are handy for tracing or manuals but no sane
+user will ever use them, I expect. However, at some point I will clean up this
+old \MKIV\ mess. This code might end up in a module outside the core.
+
+\stopsubsubject
+
+\startsubsubject[title={trac: tracing}]
+
+A lot of tracing is possible in the \LUA\ code, which can be controlled from the
+\TEX\ end using generic enable and disable commands. At the macro level we do
+have some tracing but this will be replaced by a similar mechanism. This means
+that many \type {\tracewhatevertrue} directives will go away and be replaced.
+This is of course introducing some incompatibility but normally users don't use
+this in styles.
+
+\stopsubsubject
+
+\startsubsubject[title={type: typescripts}]
+
+We already mentioned that typescripts relate to fonts. Traditionally this is a
+layer on top of font definitions and we keep it this way. In this category there
+are also the definitions of typefaces: combinations of fonts. As we split the
+larger into smaller ones, there are many more files now. This has the added
+benefit that we use less memory as typescripts are loaded only once and stored
+permanently.
+
+\stopsubsubject
+
+\startsubsubject[title={typo: typesetting and typography}]
+
+This category is rather large in \MKIV\ as we move all code into here that
+somehow deals with special typesetting. Here we find all kinds of interesting new
+code that uses \LUA\ solutions (slower but more robust). Much has been discussed
+in articles as they are nice examples and often these are rather stable.
+
+The most important new kid on the block is margin data, which has been moved into
+this category. The new mechanism is somewhat more powerful but the code is also
+quite complex and still experimental. The functionality is roughly the same as in
+\MKII\ and older \MKIV, but there is now more advanced inheritance, a clear
+separation between placement and rendering, slightly more robust stacking, local
+anchoring (new). It was a nice challenge but took a bit more time than other
+reimplementations due to all kinds of possible interference. Also, it's not
+always easy to simulate \TEX\ grouping in a script language. Even if much more
+code is involved, it looks like the new implementation is somewhat faster. I
+expect to clean up this code a couple of times.
+
+On the agenda is not only further cleanup of all modules in this category, but
+also more advanced control over paragraph building. There is a parbuilder written
+in \LUA\ on my machine for years already which we use for experiments and in the
+process a more \LUATEX-ish (and efficient) way of dealing with protrusion has
+been explored. But for this to become effective, some of the \LUATEX\ backend
+code has to be reorganized and Hartmut wants do that first. In fact, we can then
+backport the new approach to the built|-|in builder, which is not only faster but
+also more efficient in terms of memory usage.
+
+\stopsubsubject
+
+\startsubsubject[title={unic: \UNICODE\ vectors and helpers}]
+
+As \UNICODE\ support is now native all the \MKII\ code (mostly vectors and
+converters) is gone. Only a few helpers remain and even these might go away.
+Consider this category obsolete and replaced by the \type {char} category.
+
+\stopsubsubject
+
+\startsubsubject[title={util: utility functions}]
+
+These are \LUA\ files that are rather stable. Think of parsers, format
+generation, debugging, dimension helpers, etc. Like the data category, this one
+is loaded quite early.
+
+\stopsubsubject
+
+\startsubsubject[title={Other \TEX\ files}]
+
+Currently there are the above categories which can be recognized by filename and
+prefix in macro names. But there are more files involved. For instance, user
+extensions can go into these categories as well but they need names starting with
+something like \type {xxxx-imp-} with \type {xxxx} being the category.
+
+Then there are modules that can be recognized by their prefix: \type {m-} (basic
+module), \type {t-} (third party module), \type {x-} (\XML|-|specific module),
+\type {u-} (user module), \type {p-} (private module). Some modules that Wolfgang
+and Aditya are working on might end up in the core distribution. In a similar
+fashion some seldom used core code might get moved to (auto|-|loaded) modules.
+
+There are currently many modules that provide tracing for mechanisms (like font
+and math) and these need to be normalized into a consistent interface. Often such
+modules show up when we work on an aspect of \CONTEXT\ or \LUATEX\ and at that
+moment integration is not high on the agenda.
+
+\stopsubsubject
+
+\startsubsubject[title={\METAPOST\ files}]
+
+A rather fundamental change in \METAPOST\ is that it no longer has a format (mem
+file). Maybe at some point it will read \type {.gz} files, but all code is loaded
+at runtime.
+
+For this reason I decided to split the files for \MKII\ and \MKIV\ as having
+version specific code in a common set no longer makes much sense. This means that
+already for a while we have \type {.mpii} and \type {.mpiv} files with the latter
+category being more efficient because we delegate some backend|-|related issues
+to \CONTEXT\ directly. I might split up the files for \MKIV\ a bit more so that
+selective loading is easier. This gives a slight performance boost when working
+over a network connection.
+
+\stopsubsubject
+
+\startsubsubject[title={\LUA\ files}]
+
+There are some generic helper modules, with names starting with \type {l-}. Then
+there are the \type {mtx-*} scripts for all kinds of management tasks with the
+most important one being \type {mtx-context} for managing a \TEX\ run.
+
+\stopsubsubject
+
+\startsubsubject[title={Generic files}]
+This leaves the bunch of generic files that provides \OPENTYPE\ support to
+packages other than \CONTEXT. Much time went into moving \CONTEXT|-|specific code
+out of the way and providing a better abstract interface. This means that new
+\CONTEXT\ code (we provide more font magic) will be less likely to interfere and
+integration is easier. Of course there is a penalty for \CONTEXT\ but it is
+bearable. And yes, providing generic code takes quite a lot of time so I
+sometimes wonder why I did it in the first place, but currently the maintenance
+burden is rather low. Khaled Hosny is responsible for bridging this code to
+\LATEX.
+
+\stopsubsubject
+
+\stopsection
+
+\startsection[title={What next}]
+
+Here ends this summary of the current state of \CONTEXT. I expect to spend the
+rest of the year on further cleaning up. I'm close to halfway now. What I really
+like is that many users upgrade as soon as there is a new beta, and as in a
+rewrite typos creep in, I therefore often get a fast response.
+
+Of course it helps a lot that Wolfgang Schuster, Aditya Mahajan, and Luigi Scarso
+know the code so well that patches show up on the list shortly after a problem
+gets reported. Also, for instance Thomas Schmitz uses the latest betas in
+academic book production, presentations, lecture notes and more, and so provides
+invaluable fast feedback. And of course Mojca Miklavec keeps all of it (and us)
+in sync. Such a drastic cleanup could not be done without their help. So let's
+end this status report with \unknown\ a big thank you to all those (unnamed)
+patient users and contributors.

+\startsection [title={Introduction}]
+
+When Dave Walden asked me if \TEX\ (or \CONTEXT) can generate ebooks we exchanged
+a bit of mail on the topic. Although I had promised myself never to fall into the
+trap of making examples for the sake of proving something I decided to pick up an
+experiment that I had been doing with a manual in progress and look into the
+\HTML\ side of that story. After all, occasionally on the \CONTEXT\ list similar
+questions are asked, like \quotation {Can \CONTEXT\ produce \HTML ?}. \footnote
+{This text appeared in the \EUROTEX\ 2011 proceedings and TUGBoat 101. Thanks to
+Karl Berry for correcting it.}
+
+\stopsection
+
+\startsection [title={Nothing new}]
+
+When you look at what nowadays is presented as an ebook document, there is not
+much new going on. Of course there are very advanced and interactive documents,
+using techniques only possible with recent hardware and programs, but the average
+ebook is pretty basic. This is no surprise. When you take a novel, apart from
+maybe a cover or an occasional special formatting of section titles, the
+typesetting of the content is pretty straightforward. In fact, given that
+formatters like \TEX\ have been around that can do such jobs without much
+intervention, it takes quite some effort to get that job done badly. It was a bit
+shocking to notice that on one of the first e-ink devices that became available
+the viewing was quite good, but the help document was just some word processor
+output turned into bad|-|looking \PDF. The availability of proper hardware does
+not automatically trigger proper usage.
+
+I can come up with several reasons why a novel published as an ebook does not
+look much more interesting and in many cases looks worse. First of all it has to
+be produced cheaply, because there is also a printed version and because the
+vendor of some devices also want to make money on it (or even lock you into their
+technology or shop). Then, it has to be rendered on various devices so the least
+sophisticated one sets the standard. As soon as it gets rendered, the resolution
+is much worse than what can be achieved in print, although nowadays I've seen
+publishers go for quick and dirty printing, especially for reprints.
+
+Over a decade ago, we did some experiments with touch screen computers. They had
+a miserable battery life, a slow processor and not much memory, but the
+resolution was the same as on the now fashionable devices. They were quite
+suitable for reading but even in environments where that made sense (for instance
+to replace carrying around huge manuals), such devices never took off. Nowadays
+we have wireless access and \USB\ sticks and memory cards to move files around,
+which helps a lot. And getting a quality comparable to what can be done today was
+no big deal, at least from the formatting point of view.
+
+In the \CONTEXT\ distribution you will find several presentation styles that can
+serve as bases for an ebook style. Also some of the \CONTEXT\ manuals come with
+two versions: one for printing and one for viewing on the screen. A nice example
+is the \METAFUN\ manual (see \in {figure} [fig:metafun]) where each page has a
+different look.
+
+\placefigure
+  [here]
+  [fig:metafun]
+  {A page from the \METAFUN\ manual.}
+  {\externalfigure[ebook-metafun-2.png][width=\textwidth]}
+
+It must be said that the (currently only black and white) devices that use
+electronic ink have a perceived resolution that is higher than their
+specifications, due to the semi|-|analog way the \quote {ink} behaves. In a
+similar fashion clever anti|-|aliasing can do wonders on \LCD\ screens. On the
+other hand they are somewhat slow and a display refresh is not that convenient.
+Their liquid crystal counterparts are much faster but they can be tiresome to
+look at for a long time and reading a book on it sitting in the sun is a no|-|go.
+Eventually we will get there and I'm really looking forward to seeing the first
+device that will use a high resolution electrowetting \CMYK\ display. \footnote
+{http://www.liquavista.com/files/LQV0905291LL5-15.pdf} But no matter what device
+is used, formatting something for it is not the most complex task at hand.
+
+\stopsection
+
+\startsection[title={Impact}]
+
+Just as with phones and portable audio devices, the market for tablets and
+ebook|-|only devices is evolving rapidly. While writing this, at work I have one
+ebook device and one tablet. The ebook device is sort of obsolete because the
+e-ink screen has deteriorated even without using it and it's just too slow to be
+used for reference manuals. The tablet is nice, but not that suitable for all
+circumstances: in the sun it is unreadable and at night the backlight is rather
+harsh. But, as I mentioned in the previous section, I expect this to change.
+
+If we look at the investment, one needs good arguments to buy hardware that is
+seldom used and after a few years is obsolete. Imagine that a family of four has
+to buy an ebook device for each member. Add to that the cost of the books and you
+quickly can end up with a larger budget than for books. Now, imagine that you
+want to share a book with a friend: will you give him or her the device? It might
+be that you need a few more devices then. Of course there is also some data
+management needed: how many copies of a file are allowed to be made and do we
+need special programs for that? And if no copy can be made, do we end up swapping
+devices? It is hard to predict how the situation will be in a few years from now,
+but I'm sure that not everyone can afford this rapid upgrading and redundant
+device approach.
+
+A friend of mine bought ebook devices for his children but they are back to paper
+books now because the devices were not kid|-|proof enough: you can sit on a book
+but not on an ebook reader.
+
+The more general devices (pads) have similar problems. I was surprised to see
+that an iPad is a single user device. One can hide some options behind passwords
+but I'm not sure if parents want children to read their mail, change preferences,
+install any application they like, etc. This makes pads not that family friendly
+and suggests that such a personal device has to be bought for each member. In
+which case it suddenly becomes a real expensive adventure. So, unless the prices
+drop drastically, pads are not a valid large scale alternative for books yet.
+
+It might sound like I'm not that willing to progress, but that's not true. For
+instance, I'm already an enthusiastic user of a media player infrastructure.
+\footnote {The software and hardware was developed by SlimDevices and currently
+is available as Logitech Squeezeserver. Incidentally I can use the iPad as an
+advanced remote control.} The software is public, pretty usable, and has no
+vendor lock|-|in. Now, it would make sense to get rid of traditional audio media
+then, but this is not true. I still buy \CD{}s if only because I then can rip
+them to a proper lossless audio format (\FLAC). The few \FLAC s that I bought via
+the Internet were from self|-|publishing performers. After the download I still
+got the \CD{}s which was nice because the booklets are among the nicest that I've
+ever seen.
+
+Of course it makes no sense to scan books for ebook devices so for that we depend
+on a publishing network. I expect that at some point there will be proper tools
+for managing your own electronic books and in most cases a simple file server
+will do. And the most open device with a proper screen will become my favourite.
+Also, I would not be surprised if ten years from now, many authors will publish
+themselves in open formats and hopefully users will be honest enough to pay for
+it. I'm not too optimistic about the latter, if only because I observe that
+younger family members fetch everything possible from the Internet and don't
+bother about rights, so we definitely need to educate them. To some extent
+publishers of content deserve this behaviour because more than I like I find
+myself in situations where I've paid some 20 euro for a \CD\ only to see that
+half a year later you can get it for half the price (sometimes it also happens
+with books).
+
+Given that eventually the abovementioned problems and disadvantages will be dealt
+with, we can assume that ebooks are here and will stay forever. So let's move on
+to the next section and discuss their look and feel.
+
+\stopsection
+
+\startsection[title={Interactivity}]
+
+The nice thing about a paper book is that it is content and interface at the same
+time. It is clear where it starts and ends and going from one page to another is
+well standardized. Putting a bookmark in it is easy as you can fall back on any
+scrap of paper lying around. While reading you know how far you came and how much
+there is to come. Just as a desktop on a desktop computer does not resemble the
+average desktop, an ebook is not a book. It is a device that can render content
+in either a given or more free|-|form way.
+
+However, an electronic book needs an interface and this is also where at the
+moment it gets less interesting. Of course the Internet is a great place to
+wander around and a natural place to look for electronic content. But there are
+some arguments for buying them at a bookshop, one being that you see a lot of
+(potentially) new books, often organized in topics in one glance. It's a
+different way of selecting. I'm not arguing that the Internet is a worse place,
+but there is definitely a difference: more aggressive advertisements, unwanted
+profiling that can narrow what is presented to a few choices.
+
+Would I enter a bookshop if on the display tables there were stacks of (current)
+ebook devices showing the latest greatest books? I can imagine that at some point
+we will have ebook devices that have screens that run from edge to edge and then
+we get back some of the appeal of book designs. It is that kind of future devices
+that we need to keep in mind when we design electronic documents, especially when
+after some decades we want them to be as interesting as old books can be. Of
+course this is only true for documents that carry the look and feel of a certain
+time and place and many documents are thrown away. Most books have a short
+lifespan due to the quality of the paper and binding so we should not become too
+sentimental about the transition to another medium.
+
+Once you're in the process of reading a book not much interfacing is needed.
+Simple gestures or touching indicated areas on the page are best. For more
+complex documents the navigation could be part of the design and no screen real
+estate has to be wasted by the device itself. Recently I visited a
+school|-|related exhibition and I was puzzled by the fact that on an electronic
+schoolboard so much space was wasted on colorful nonsense. Taking some 20\% off
+each side of such a device brings down the effective resolution to 600 pixels so
+we end up with 10 pixels or less per character (shown at about 1 cm width). At
+the same exhibition there were a lot of compensation programs for dyslexia
+advertised, and there might be a relationship.
+
+\stopsection
+
+\startsection[title={Formatting}]
+
+So how important is the formatting? Do we prefer reflow on demand or is a more
+frozen design that suits the content and expresses the wish of the author more
+appropriate? In the first case \HTML\ is a logical choice, and in the second one
+\PDF\ makes sense. You design a nice \HTML\ document but at some point the reflow
+gets in the way. And yes, you can reflow a \PDF\ file but it's mostly a joke.
+Alternatively one can provide both which is rather trivial when the source code
+is encoded in a systematic way so that multiple output is a valid option. Again,
+this is not new and mostly a matter of a publisher's policy. It won't cost more
+to store in neutral formats and it has already been done cheaply for a long time.
+
+Somewhat interfering in this matter is digital rights management. While it is
+rather customary to buy a book and let friends or family read the same book, it
+can get complicated when content is bound to one (or a few) devices. Not much
+sharing there, and in the worst case, no way to move your books to a better
+device. Each year in the Netherlands we have a book fair and bookshops give away
+a book specially written for the occasion. This year the book was also available
+as an ebook, but only via a special code that came with the book. I decided to
+give it a try and ended up installing a broken application, i.e.\ I could not get
+it to load the book from the Internet, and believe me, I have a decent machine
+and the professional \PDF\ viewer software that was a prerequisite.

+\startsection[title={Using \TEX}]
+
+So, back to Dave's question: if \CONTEXT\ can generate ebooks in the \EPUB\
+format. Equally interesting is the question if \TEX\ can format an \EPUB\ file
+into a (say) \PDF\ file. As with much office software, an \EPUB\ file is nothing
+more than a zip file with a special suffix in which several resources are
+combined. The layout of the archive is prescribed. However, by demanding that the
+content itself is in \HTML\ and by providing a stylesheet to control the
+renderer, we don't automatically get properly tagged and organized content. When
+I first looked into \EPUB, I naively assumed that there was some well|-|defined
+structure in the content; turns out this is not the case.
+
+Let's start by answering the second question. Yes, \CONTEXT\ can be used to
+convert an \EPUB\ file into a \PDF\ file. The natural followup question is if it
+can be done automatically, and then some more nuance is needed: it depends. If
+you download the \EPUB\ for \quotation {A tale of two cities} from Charles
+Dickens from the Gutenberg Project website and look into a chapter you will see
+this:
+
+\starttyping
+<h1 id="pgepubid00000">A TALE OF TWO CITIES</h1>
+<h2 id="pgepubid00001">A STORY OF THE FRENCH REVOLUTION</h2>
+<p><br/></p>
+<h2>By Charles Dickens</h2>
+<p><br/>
+<br/></p>
+<hr/>
+<p><br/>
+<br/></p>
+<h2 id="pgepubid00002">Contents</h2>
+\stoptyping
+
+What follows is a table of contents formatted using \HTML\ tables
+and after that
+
+\starttyping
+<h2 id="pgepubid00004">I. The Period</h2>
+\stoptyping
+
+So, a level two header is used for the subtitle of the book as well as a regular
+chapter. I must admit that I had to go on the Internet to find this snippet as I
+wanted to check its location. On my disk I had a similar file from a year ago
+when I first looked into \EPUB. There I have:
+
+\starttyping
+<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
+  <head>
+    <title>I | A Tale of Two Cities</title>
+    ....
+  </head>
+  <body>
+    <div class="body">
+      <div class="chapter">
+        <h3 class="chapter-title">I</h3>
+        <h4 class="chapter-subtitle">The Period</h4>
+\stoptyping
+
+I also wanted to make sure if the interesting combination of third and fourth
+level head usage was still there but it seems that there are several variants
+available. It is not my intention to criticize the coding, after all it is valid
+\HTML\ and can be rendered as intended. Nevertheless, the first snippet
+definitely looks worse, as it uses breaks instead of \CSS\ spacing directives and
+the second wins on obscurity due to the abuse of the head element.
+
+These examples answer the question about formatting an arbitrary \EPUB\ file:
+\quotation {no}. We can of course map the tagging to \CONTEXT\ and get pretty
+good results but we do need to look at the coding.
+
+As such books are rather predictable it makes sense to code them in a more
+generic way. That way generic stylesheets can be used to render the book directly
+in a viewer and generic \CONTEXT\ styles can be used to format it differently,
+e.g.\ as \PDF.
+
+Of course, if I were asked to set up a workflow for formatting ebooks, that would
+be relatively easy. For instance the Gutenberg books are available as raw text
+and that can be parsed to some intermediate format or (with \MKIV) interpreted
+directly.
+
+Making a style for a specific instance, like the Dickens book, is not that
+complex either. After all, the amount of encoding is rather minimal and special
+bits and pieces like a title page need special design anyway. The zipped file can
+be processed directly by \CONTEXT, but this is mostly just a convenience.
+
+As \EPUB\ is just a wrapper, the next question is if \CONTEXT\ can produce some
+kind of \HTML\ and the answer to that question is positive. Of course this only
+makes sense when the input is a \TEX\ source, and we have argued before that when
+multiple output is needed the user might consider a different starting point.
+After all, \CONTEXT\ can deal with \XML\ directly.
+
+The main advantage of coding in \TEX\ is that the source remains readable and for
+some documents it's certainly more convenient, like manuals about \TEX. In the
+reference manual \quote {\CONTEXT\ \LUA\ Documents} (\CLD) there are the
+following commands:
+
+\starttyping
+\setupbackend
+  [export=yes]
+
+\setupinteraction
+  [title=Context Lua Documents,
+   subtitle=preliminary version,
+   author=Hans Hagen]
+\stoptyping
+
+At the cost of at most 10\% extra runtime an \XML\ export is generated in
+addition to the regular \PDF\ file. Given that you have a structured \TEX\ source
+the exported file will have a decent structure as well and you can therefore
+transform the file into something else, for instance \HTML. But, as we already
+have a good|-|looking \PDF\ file, the only reason to have \HTML\ as well is for
+reflowing. Of course wrapping up the \HTML\ into an \EPUB\ structure is not that
+hard. We can probably even get away from wrapping because we have a single
+self|-|contained file.
+
+\placefigure
+  {A page from the \CLD\ manual in \PDF.}
+  {\externalfigure[ebook-pdf.png][width=\textwidth]}
+
+The \type {\setupbackend} command used in the \CLD\ manual has a few
+more options:
+
+\starttyping
+\setupbackend
+  [export=cld-mkiv-export.xml,
+   xhtml=cld-mkiv-export.xhtml,
+   css={cld-mkiv-export.css,mathml.css}]
+\stoptyping
+
+We explicitly name the export file and in addition specify a stylesheet and an
+alternative \XHTML\ file. If you can live without hyperlinks the \XML\ file
+combined with the cascading style sheet will do a decent job of controlling the
+formatting.
+
+In the \CLD\ manual chapters are coded like this:
+
+\starttyping
+\startchapter[title=A bit of Lua]
+
+\startsection[title=The language]
+\stoptyping
+
+The \XML\ output of this
+
+\starttyping
+<division detail='bodypart'>
+  <section detail='chapter' location='aut:3'>
+    <sectionnumber>1</sectionnumber>
+    <sectiontitle>A bit of Lua</sectiontitle>
+    <sectioncontent>
+      <section detail='section'>
+        <sectionnumber>1.1</sectionnumber>
+        <sectiontitle>The language</sectiontitle>
+        <sectioncontent>
+\stoptyping
+
+The \HTML\ version has some extra elements:
+
+\starttyping
+<xhtml:a name="aut_3">
+  <section location="aut:3" detail="chapter">
+\stoptyping
+
+The table of contents and cross references have \type {xhtml:a} elements too but
+with the \type {href} attribute. It's interesting to search the web for ways to
+avoid this, but so far no standardized solution for mapping \XML\ elements onto
+hyperlinks has been agreed upon. In fact, getting the \CSS\ mapping done was not
+that much work but arriving at the conclusion that (in 2011) these links could
+only be done in a robust way using \HTML\ tags took more time. \footnote {In this
+example we see the reference \type {aut:3} turned into \type {aut_1}. This is
+done because some browsers like to interpret this colon as a url.} Apart from
+this the \CSS\ has enough on board to map the export onto something presentable.
+For instance:
+
+\starttyping
+sectioncontent {
+    display: block ;
+    margin-top: 1em ;
+    margin-bottom: 1em ;
+}
+
+section[detail=chapter], section[detail=title] {
+    margin-top: 3em ;
+    margin-bottom: 2em ;
+}
+
+section[detail=chapter]>sectionnumber {
+    display: inline-block ;
+    margin-right: 1em ;
+    font-size: 3em ;
+    font-weight: bold ;
+}
+\stoptyping
+
+As always, dealing with verbatim is somewhat special. The following code does the
+trick:
+
+\starttyping
+verbatimblock {
+    background-color: #9999FF ;
+    display: block ;
+    padding: 1em ;
+    margin-bottom: 1em ;
+    margin-top: 1em ;
+    font-family: "Lucida Console", "DejaVu Sans Mono", monospace ;
+}
+
+verbatimline {
+    display: block ;
+    white-space: pre-wrap ;
+}
+
+verbatim {
+    white-space: pre-wrap ;
+    color: #666600 ;
+    font-family: "Lucida Console", "DejaVu Sans Mono", monospace ;
+}
+\stoptyping
+
+The spacing before the first and after the last one differs from the spacing
+between lines, so we need some extra directives:
+
+\starttyping
+verbatimlines+verbatimlines {
+    display: block ;
+    margin-top: 1em ;
+}
+\stoptyping
+
+This will format code like the following with a bluish background and inline
+verbatim with its complement:
+
+\starttyping
+<verbatimblock detail='typing'>
+  <verbatimlines>
+    <verbatimline>function sum(a,b)</verbatimline>
+    <verbatimline>  print(a, b, a + b)</verbatimline>
+    <verbatimline>end</verbatimline>
+  </verbatimlines>
+</verbatimblock>
+\stoptyping
+
+The hyperlinks need some attention. We need to make sure that only the links and
+not the anchors get special formatting. After some experimenting I arrived at
+this:
+
+\starttyping
+a[href] {
+    text-decoration: none ;
+    color: inherit ;
+}
+
+a[href]:hover {
+    color: #770000 ;
+    text-decoration: underline ;
+}
+\stoptyping
+
+Tables are relatively easy to control. We have tabulate (nicer for text) and
+natural tables (similar to the \HTML\ model). Both get mapped into \HTML\ tables
+with \CSS\ directives. There is some detail available so we see things like this:
+
+\starttyping
+tablecell[align=flushleft] {
+    display: table-cell ;
+    text-align: left ;
+    padding: .1em ;
+}
+\stoptyping
+
+It is not hard to support more variants or detail in the export but that will
+probably only happen when I find a good reason (a project), have some personal
+need, or when a user asks for it. For instance images will need some special
+attention (conversion, etc.). Also, because we use \METAPOST\ all over the place
+that needs special care as well, but a regular (novel|-|like) ebook will not have
+such resources.
+
+\placefigure
+  {A page from \CLD\ manual in \HTML.}
+  {\externalfigure[ebook-xhtml.png][width=\textwidth]}
+
+As an extra, a template file is generated that mentions all
+elements used, like this:
+
+\starttyping
+section[detail=summary] {
+    display: block ;
+}
+\stoptyping
+
+with the inline and display properties already filled in. That way I could see
+that I still had to add a couple of directives to the final \CSS\ file. It also
+became clear that in the \CLD\ manual some math is used that gets tagged as
+\MATHML, so that needs to be covered as well. \footnote {Some more advanced
+\MATHML\ output will be available when the matrix|-|related core commands have
+been upgraded to \MKIV\ and extended to suit today's needs.} Here we need to make
+some decisions as we export \UNICODE\ and need to consider support for less
+sophisticated fonts. On the other hand, the \WTHREEC\ consortium has published
+\CSS\ for this purpose so we can use these as a starting point. It might be that
+eventually more tuning will be delegated to the \XHTML\ variant. This is not much
+extra work as we have the (then intermediate) \XML\ tree available. Thinking of
+it, we could eventually end up with some kind of \CSS\ support in \CONTEXT\
+itself.
+
+It will take some experimenting and feedback from users to get the export right,
+especially to provide a convenient way to produce so|-|called \EPUB\ files
+directly. There is already some support for this container format. If you have
+enabled \XHTML\ export, you can produce an \EPUB\ archive afterwards with:
+
+\starttyping
+mtxrun --script epub yourfile
+\stoptyping
+
+For testing the results, open source programs like \type {calibre} are quite
+useful. It will probably take a while to figure out to what extent we need to
+support formats like \EPUB, if only because such formats are adapted on a regular
+basis.
+
+\stopsection
+
+\startsection[title=The future]
+
+It is hard to predict the future. I can imagine that given the user interface
+that has evolved over ages paper books will not disappear soon. Probably there
+will be a distinction between read|-|once and throw|-|away books and those that
+you carry with you your whole life as visible proof of that life. I can also
+imagine that (if only for environmental reasons) ebooks (hopefully with stable
+devices) will dominate. In that case traditional bookshops will disappear and
+with them the need for publishers that supply them. Self|-|publishing will then
+be most interesting for authors and maybe some of them (or their helpful friends)
+will be charmed by \TEX\ and tinkering with the layout using the macro language.
+I can also imagine that at some point new media (and I don't consider an ebook a
+new medium) will dominate. And how about science fiction becoming true:
+downloading stories and information directly into our brains.
+
+It reminds me of something I need to do some day soon: get rid of old journals
+that I planned to read but never will. I would love to keep them electronically
+but it is quite unlikely that they are available and if so, it's unlikely that I
+want to pay for them again. This is typically an area where I'd consider using an
+ebook device, even if it's suboptimal. On the other hand, I don't consider
+dropping my newspaper subscription yet as I don't see a replacement for the
+regular coffeestop at the table where it sits and where we discuss the latest
+news.
+
+The nice thing about an analogue camera is that the image carrier has been
+standardized and you can buy batteries everywhere. Compare this with their
+digital cousins: all have different batteries, there are all kinds of memory
+cards, and only recently has some standardization in lenses shown up. There is a
+wide range of resolutions and aspect ratios. Other examples of standardization
+are nuts and bolts used in cars, although it took some time for the metric system
+to catch on. Books have different dimensions but it's not hard to deal with that
+property. Where desktop hardware is rather uniform everything portable is
+different. For some brands you need a special toolkit with every new device.
+Batteries cannot be exchanged and there are quite some data carriers. On the
+other hand, we're dealing with software and if we want we can support data
+formats forever. The \MICROSOFT\ operating systems have demonstrated that
+programs written years ago can still run on updates. In addition \LINUX\
+demonstrates that users can take and keep control and create an independence from
+vendors. So, given that we can still read document sources and given that they
+are well structured, we can create history|-|proof solutions. I don't expect that
+the traditional publishers will play a big role in this if only because of their
+short term agendas and because changing ownerships works against long term views.
+And programs like \TEX\ have already demonstrated having a long life span,
+although it must be said that in today's rapid upgrade cycles it takes some
+courage to stay with it and its descendants. But downward compatibility is high
+on the agenda of its users and user groups which is good in the perspective of
+discussing stable ebooks.
+
+Let's finish with an observation. Books often make a nice (birthday) present and
+finding one that suits is part of the gift. Currently a visible book has some
+advantages: when unwrapped it can be looked at and passed around. It also can be
+a topic of discussion and it has a visible personal touch. I'm not so sure if
+vouchers for an ebook have the same properties. It probably feels a bit like
+giving synthetic flowers. I don't know what percentage of books is given as
+presents but this aspect cannot be neglected. Anyway, I wonder when I will buy my
+first ebook and for who. Before that happens I'll probably have generated lots of
+them.

+\startchapter[title={Exporting XML}]
+
+\startsection [title={Introduction}]
+
+Every now and then on the the mailing list users ask if \CONTEXT\ can produce
+\HTML\ instead of for instance \PDF, and the answer has always been unsatisfying.
+In this chapter I will present the \MKIV\ way of doing this.
+
+\stopsection
+
+\startsection [title={The clumsy way}]
+
+My favourite answer to the question about how to produce \HTML\ (or more general
+\XML\ as it can be transformed) has always been: \quotation {I'd just typeset
+it!}. Take:
+
+\starttyping
+\def\MyChapterCommand#1#2{<h1>#2</h1>}
+\setuphead[chapter][command=\MyChapterCommand]
+\stoptyping
+
+Here \type {\chapter{Hello World}} will produce:
+
+\starttyping
+<h1>Hello World</h1>
+\stoptyping
+
+Now imagine that you hook such commands into all relevant environments and that
+you use a style with no header and footer lines. You use a large page (A2) and a
+small monospaced font (4pt) so that page breaks will not interfere too much. If
+you want columns, fine, just hook in some code that typesets the final columns as
+tables. In the end you will have an ugly looking \PDF\ file but by feeding it
+into \type {pdftotext} you will get a nicely formatted \HTML\ file.
+
+For some languages of course encoding issues would show up and there can be all
+kind of interferences, so eventually the amount of code dealing with it would
+have accumulated. This is why we don't follow this route.
+
+An alternative is to use \type {tex4ht} which does an impressive job for \LATEX,
+and supports \CONTEXT\ to some extent as well. As far as I know it overloads some
+code deep down in the kernel which is something \quote {not done} in the
+\CONTEXT\ universe if only because we cannot keep control over side effects. It
+also complicates maintainance of both systems.
+
+In \MKIV\ however, we do have the ability to export the document to a structured
+\XML\ file so let's have a look at that.
+
+\stopsection
+
+\startsection [title={Structure}]
+
+The ability to export to some more verbose format depends on the availability of
+structural information. As we already tag elements for the sake of tagged \PDF,
+it was tempting to see how well we could use those tags for exporting to \XML. In
+principle it is possible to use Acrobat Professional to export the content using
+tags but you can imagine that we get a better quality if we stay within the scope
+of the producing machinery.
+
+\starttyping
+\setupbackend[export=yes]
+\stoptyping
+
+This is all you need unless you want to fine tune the resulting \XML\ file. If
+you are familiar with tagged \PDF\ support in \CONTEXT, you will recognize the
+result. When you process the following file:
+
+\typefile{exported-001.tex}
+
+You will get a file with the suffix \type {export} that looks as follows:
+\footnote{We will omit the topmost lines in following examples.}
+
+\typefile{exported-001.export}
+
+It's no big deal to postprocess such a file. In that case one can for instance
+ignore the chapter number or combine the number and the title. Of course
+rendering information is lost here. However, sometime it makes sense to export
+some more details. Take the following table:
+
+\typefile[range=2]{exported-002.tex}
+
+Here we need to preserve the span related information as well as cell specific
+alignments as for tables this is an essential part of the structure.
+
+\typefile[range=7]{exported-002.export}
+
+The tabulate mechanism is quite handy for regular text especially when the
+content of cells has to be split over pages. As each line in a paragraph in a
+tabulate becomes a cell, we need to reconstruct the paragraphs from the (split)
+alignment cells.
+
+\typefile[range=2]{exported-003.tex}
+
+This becomes:
+
+\typefile[range=7]{exported-003.export}
+
+The \type {<break/>} elements are injected automatically between paragraphs. We
+could tag each paragraph individually but that does not work that well when we
+have for instance a quotation that spans multiple paragraphs (and maybe starts in
+the middle of one). An empty element is not sensitive for this and is still a
+signal that vertical spacing is supposed to be applied.
+
+\stopsection
+
+\startsection[title=The implementation]
+
+We implement tagging using attributes. The advantage of this is that it does not
+interfere with typesetting, but a disadvantage is that not all parent elements
+are visible. When we encounter some content, we're in the innermost element so if
+we want to do something special, we need to deduce the structure from the current
+child. This is no big deal as we have that information available at each child
+element in the tree.
+
+The first implementation just flushed the \XML\ on the fly (i.e.\ when traversing
+the node list) but when I figured out that collapsing was needed for special
+cases like tabulated paragraphs this approach was no longer valid. So, after some
+experiments I decided to build a complete structure tree in memory \footnote {We
+will see if this tree will be used for other purposes in the future.}. This
+permits us to handle situations like the following:
+
+\typefile[range=2]{exported-005.tex}
+
+Here we get:
+
+\typefile[range=7]{exported-005.export}
+
+The \type {symbol} and \type {packed} attributes are first seen at the \type
+{itemcontent} level (the innermost element) so when we flush the \type
+{itemgroup} element's attributes we need to look at the child elements (content)
+that actually carry the attribute.\footnote {Only glyph nodes are investigated
+for structure.}
+
+I already mentioned collapsing. As paragraphs in a tabulate get split into cells,
+we encounter a mixture that cannot be flushed sequentially. However, as each cell
+is tagged uniquely we can append the lines within a cell. Also, as each paragraph
+gets a unique number, we can add breaks before a new paragraph starts. Collapsing
+and adding breakpoints is done at the end, and not per page, as paragraphs can
+cross pages. Again, thanks to the fact that we have a tree, we can investigate
+content and do this kind of manipulations.
+
+Moving data like footnotes are somewhat special. When notes are put on the page
+(contrary to for instance end notes) the so called \quote {insert} mechanism is
+used where their content is kept with the line where it is defined. As a result
+we see them end up instream which is not that bad a coincidence. However, as in
+\MKIV\ notes are built on top of (enumerated) descriptions, we need to
+distinguish them somehow so that we can cross reference them in the export.
+
+\typefile[range=2]{exported-006.tex}
+
+Currently this will end up as follows:
+
+\typefile[range=7]{exported-006.export}
+
+Graphics are also tagged and the \type {image} element reflects the included
+image.
+
+\typefile[range=2]{exported-007.tex}
+
+If the image sits on another path then that path shows up in an attribute and
+when a page other than~1 is taken from the (pdf) image, it gets mentioned as
+well.
+
+\typefile[range=7]{exported-007.export}
+
+Cross references are another relevant aspect of an export. In due time we will
+export them all. It's not so much complicated because all information is there
+but we need to hook some code into the right spot and making examples for those
+cases takes a while as well.
+
+\typefile[range=2]{exported-009.tex}
+
+We export references in the \CONTEXT\ specific way, so no
+interpretation takes place.
+
+\typefile[range=7]{exported-009.export}
+
+As \CONTEXT\ has an integrated referencing system that deals with internal as
+well as external references, url's, special interactive actions like controlling
+widgets and navigations, etc.\ and we export the raw reference specification as
+well as additional attributes that provide some detail.
+
+\typefile[range=2]{exported-013.tex}
+
+Of course, when postprocessing the exported data, you need to take these variants
+into account.
+
+\typefile[range=7]{exported-013.export}
+
+\stopsection
+
+\startsection[title=Math]
+
+Of course there are limitations. For instance \TEX ies doing math might wonder if
+we can export formulas. To some extent the export works quite well.
+
+\typefile[range=2]{exported-008.tex}
+
+This results in the usual rather verbose presentation \MATHML:
+
+\typefile[range=7]{exported-008.export}
+
+More complex math (like matrices) will be dealt with in due time as for this
+Aditya and I have to take tagging into account when we revisit the relevant code
+as part of the \MKIV\ cleanup and extensions. It's not that complex but it makes
+no sense to come up with intermediate solutions.
+
+Display verbatim is also supported. In this case we tag individual lines.
+
+\typefile[range=2]{exported-010.tex}
+
+The export is not that spectacular:
+
+\typefile[range=7]{exported-010.export}
+
+A rather special case are marginal notes. We do tag them because they
+often contain usefull information.
+
+\typefile[range=2]{exported-012.tex}
+
+The output is currently as follows:
+
+\typefile[range=7]{exported-012.export}
+
+However, this might change in future versions.
+
+\stopsection
+
+\startsection[title=Formatting]
+
+The output is formatted using indentation and newlines. The extra run time needed
+for this (actually, quite some of the code is related to this) is compensated by
+the fact that inspecting the result becomes more convenient. Each environment has
+one of the properties \type {inline}, \type {mixed} and \type {display}. A
+display environment gets newlines around it and an inline environment none at
+all. The mixed variant does something in between. In the following example we tag
+some user elements, but you can as well influence the built in ones.
+
+\typefile[range=2]{exported-004.tex}
+
+This results in:
+
+\typefile[range=7]{exported-004.export}
+
+Keep in mind that elements have no influence on the typeset result apart from
+introducing spaces when used this way (this is not different from other \TEX\
+commands). In due time the formatting might improve a bit but at least we have
+less chance ending up with those megabyte long one||liners that some applications
+produce.
+
+\stopsection
+
+\startsection[title=A word of advise]
+
+In (for instance) \HTML\ class attributes are used to control rendering driven by
+stylesheets. In \CONTEXT\ you can often define derived environments and their
+names will show up in the detail attribute. So, if you want control at that level
+in the export, you'd better use the structure related options built in \CONTEXT,
+for instance:
+
+\typefile[range=2]{exported-011.tex}
+
+This gives two different sections:
+
+\typefile[range=7]{exported-011.export}
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+It is an open question if such an export is useful. Personally I never needed a
+feature like this and there are several reasons for this. First of all, most of
+my work involves going from (often complex) \XML\ to \PDF\ and if you have \XML\
+as input, you can also produce \HTML\ from it. For documents that relate to
+\CONTEXT\ I don't need it either because manuals are somewhat special in the
+sense that they often depend on showing something that ends up on paper (or its
+screen counterpart) anyway. Loosing the makeup also renders the content somewhat
+obsolete. But this feature is still a nice proof of concept anyway.

+\startsection [title={Introduction}]
+
+When \TEX\ came around it shipped with its own fonts. At that moment the \TEX\
+font universe was a small and well known territory. The \quote {only} hassle was
+that one needed to make sure that the right kind of bitmap was available for the
+printer.
+
+When other languages than English came into the picture things became more
+complex as now fonts instances in specific encodings showed up. After a couple of
+years the by then standardised \TEX\ distributions carried tens of thousands of
+font files. The reason for this was simple: \TEX\ fonts could only have 256
+characters and therefore there were quite some encodings. Also, large \CJK\ fonts
+could easily have hundreds of metric files per font. Distributions also provide
+metrics for commercial fonts although I could never use them and as a result have
+many extra metric files in my personal trees (generated by \TEXFONT). \footnote
+{Distributions like \TEX Live have between 50.000 and 100.000 files, but
+derivatives like the \CONTEXT\ minimals are much smaller.}
+
+At the input side many problems related to encodings were solved by \UNICODE. So,
+when the more \UNICODE\ aware fonts showed up, it looked like things would become
+easier. For instance, no longer were choices for encodings needed. Instead one
+had to choose features and enable languages and scripts and so the problem of the
+multitude of files was replaced by the necessity to know what some font actually
+provides. But still, for the average user it can be seen as an improvement.
+
+A rather persistent problem remained, especially for those who want to use
+different fonts and or need to install fonts on the system that come from
+elsewhere (either free or commercial): the names used for fonts. You may argue
+that modern \TEX\ engines and macro packages can make things easier, especially
+as one can call up fonts by their names instead of their filenames, but actually
+the problem has worsened. With traditional \TEX\ you definitely get an error when
+you mistype a filename or call for a font that is not on your system. The more
+modern \TEX's macro packages can provide fallback mechanisms and you can end up
+with something you didn't ask for.
+
+For years one of the good things of \TEX\ was its stability. If we forget about
+changes in content, macro packages and|/|or hyphenation patterns, documents could
+render more or less the same for years. This is because fonts didn't change.
+However, now that fonts are more complex, bugs gets fixed and thereby results can
+differ. Or, if you use platform fonts, your updated operating system might have
+new or even different variants. Or, if you access your fonts by fontname, a
+lookup can resolve differently.
+
+The main reason for this is that fontnames as well as filenames of fonts are
+highly inconsistent across vendors, within vendors and platforms. As we have to
+deal with this matter, in \MKIV\ we have several ways to address a font: by
+filename, by fontname, and by specification. In the next sections I will describe
+all three.
+
+\stopsection
+
+\startsection [title={Method 1: file}]
+
+The most robust way to specify what fonts is to be used is the filename. This is
+done as follows:
+
+\starttyping
+\definefont[SomeFont][file:lmmono10-regular]
+\stoptyping
+
+A filename lookup is case insensitive and the name you pass is exact. Of course
+the \type {file:} prefix (as with any prefix) can be used in font synonyms as
+well. You may add a suffix, so this is also valid:
+
+\starttyping
+\definefont[SomeFont][file:lmmono10-regular.otf]
+\stoptyping
+
+By default \CONTEXT\ will first look for an \OPENTYPE\ font so in both cases you
+will get such a font. But how do you know what the filename is? You can for
+instance check it out with:
+
+\starttyping
+mtxrun --script font --list --file --pattern="lm*mono"
+\stoptyping
+
+This reports some information about the file, like the weight, style, width,
+fontname, filename and optionally the subfont id and a mismatch between the
+analysed weight and the one mentioned by the font.

+\startsection [title={Method 1: name}]
+
+Instead of lookup by file, you can also use names. In the font database we store
+references to the fontname and fullname as well as some composed names from
+information that comes with the font. This permits rather liberal naming and the
+main reason is that we can more easily look up fonts. In practice you will use
+names that are as close to the filename as possible.
+
+\starttyping

+It does not show from this list but with name lookups first \OPENTYPE\ fonts are

+
+\starttyping
+mtxrun --script font --list --name --pattern="latinmodern*mono" --all

+will give:

+\stopntyping
+
+Watch the 9 point version in this list. It happens that there are 9, 10 and 12
+point regular variants but all those extras come in 10 point only. So we get a
+mix and if you want a specific design size you really have to be more specific.
+Because one font can be registered with its fontname, fullname etc.\ it can show
+up more than once in the list. You get what you ask for.
+
+With this obscurity you might wonder why names make sense as lookups. One
+advantage is that you can forget about special characters. Also, Latin Modern
+with its design sizes is probably the worst case. So, although for most fonts a
+name like the following will work, for Latin Modern it gives one of the design
+sizes:
+
+\starttyping
+\definefont[SomeFont][name:latinmodernmonolightbolditalic]
+\stoptyping
+
+But this is quite okay:
+
+\starttyping
+\definefont[SomeFont][name:lmmonolt10boldoblique]
+\stoptyping
+
+So, in practice this method will work out as well as the file method but
+you can best check if you get what you want.
+
+\stopsection
+
+\startsection [title={Method 1: spec}]
+
+We have now arrived at the third method, selecting by means of a specification.
+This time we take the familyname as starting point (although we have some
+fallback mechanisms):
+
+\starttyping
+\definefont[SomeSerif]          [spec:times]
+\definefont[SomeSerifBold]      [spec:times-bold]
+\definefont[SomeSerifItalic]    [spec:times-italic]
+\definefont[SomeSerifBoldItalic][spec:times-bold-italic]
+\stoptyping
+
+The patterns are of the form:
+
+\starttyping
+spec:name-weight-style-width
+spec:name-weight-style
+spec:name-style
+\stoptyping
+
+When only the name is used, it actually boils down to:
+
+\starttyping
+spec:name-normal-normal-normal
+\stoptyping
+
+So, this is also valid:
+
+\starttyping
+spec:name-normal-italic-normal
+spec:name-normal-normal-condensed
+\stoptyping
+
+Again we can consult the database:
+
+\starttyping
+mtxrun --script font --list --spec lmmono-normal-italic
+\stoptyping
+
+This prints the following list. The first column is the familyname, the fifth
+column the fontname:
+
+\startntyping
+latinmodernmono       normal   italic   normal   lmmono10italic        lmmono10-italic.otf
+latinmodernmonoprop   normal   italic   normal   lmmonoprop10oblique   lmmonoprop10-oblique.otf
+lmmono10              normal   italic   normal   lmmono10italic        lmtti10.afm
+lmmonoprop10          normal   italic   normal   lmmonoprop10oblique   lmvtto10.afm
+lmmonocaps10          normal   italic   normal   lmmonocaps10oblique   lmtcso10.afm
+latinmodernmonocaps   normal   italic   normal   lmmonocaps10oblique   lmmonocaps10-oblique.otf
+\stopntyping
+
+Watch the \OPENTYPE\ and \TYPEONE\ mix. As we're just investigating here, the
+lookup looks at the fontname and not at the familyname. At the \TEX\ end you use
+the familyname:
+
+\starttyping
+\definefont[SomeFont][spec:latinmodernmono-normal-italic-normal]
+\stoptyping
+
+So, we have the following ways to access this font:
+
+\starttyping
+\definefont[SomeFont][file:lmmono10-italic]
+\definefont[SomeFont][file:lmmono10-italic.otf]
+\definefont[SomeFont][name:lmmono10italic]
+\definefont[SomeFont][spec:latinmodernmono-normal-italic-normal]
+\stoptyping
+
+As \OPENTYPE\ fonts are prefered over \TYPEONE\ there is not much chance of a
+mixup.
+
+As mentioned in the introduction, qualifications are somewhat inconsistent. Among
+the weight we find: black, bol, bold, demi, demibold, extrabold, heavy, light,
+medium, mediumbold, regular, semi, semibold, ultra, ultrabold and ultralight.
+Styles are: ita, ital, italic, roman, regular, reverseoblique, oblique and
+slanted. Examples of width are: book, cond, condensed, expanded, normal and thin.
+Finally we have alternatives which can be anything.
+
+When doing a lookup, some normalizations takes place, with the default always
+being \quote {normal}. But still the repertoire is large:

+\startsection[title={The font database}]
+
+In \MKIV\ we use a rather extensive font database which in addition to bare
+information also contains a couple of hashes. When you use \CONTEXT\ \MKIV\ and
+install a new font, you have to regenerate the file database. In a next \TEX\ run
+this will trigger a reload of the font database. Of course you can also force a
+reload with:
+
+\starttyping
+mtxrun --script font --reload
+\stoptyping
+
+As a summary we mention a few of the discussed calls of this script:
+
+\startntyping
+mtxrun --script font --list somename (== --pattern=*somename*)
+
+mtxrun --script font --list --name somename
+mtxrun --script font --list --name --pattern=*somename*

+
+mtxrun --script font --list --file somename
+mtxrun --script font --list --file --pattern=*somename*

+
+Regular users never deal with the font database directly. However, if you write

+    style = "normal",
+    variant = "",
+    weight = "normal",
+    width = "normal",
+}
+\stoptyping
+
+Another example is Helvetica Neue Italic:
+
+\starttyping
+{
+    designsize = 0,
+    familyname = "helveticaneue",
+    filename = "HelveticaNeue.ttc",
+    fontname = "helveticaneueitalic",
+    fontweight = "book",
+    format = "ttc",
+    fullname = "helveticaneueitalic",
+    maxsize = 0,
+    minsize = 0,
+    rawname = "Helvetica Neue Italic",
+    style = "italic",
+    subfont = 8,
+    variant = "",
+    weight = "normal",
+    width = "normal",
+}
+\stoptyping
+
+As you can see, some fields can be meaningless, like the sizes. As using the low
+level \TEX\ interface assumes some knowledge, we stick here to an example:
+
+\starttyping
+\def\TestLookup#1%
+  {\dolookupfontbyspec{#1}
+   pattern: #1, found: \dolookupnoffound
+   \blank
+   \dorecurse {\dolookupnoffound} {%
+     \recurselevel:~\dolookupgetkeyofindex{fontname}{\recurselevel}%
+     \quad
+   }%
+   \blank}
+
+\TestLookup{familyname=helveticaneue}
+\TestLookup{familyname=helveticaneue,weight=bold}
+\TestLookup{familyname=helveticaneue,weight=bold,style=italic}
+\stoptyping
+
+You can use the following commands:
+
+\starttyping
+\dolookupfontbyspec    {key=value list}
+\dolookupnoffound
+\dolookupgetkeyofindex {key}{index}
+\dolookupgetkey        {key}
+\stoptyping
+
+First you do a lookup. After that there can be one or more matches and you can
+access the fields of each match. What you do with the information is up to
+yourself.
+
+\stopsection
+
+\startsection[title={A few remarks}]
+
+The fact that modern \TEX\ engines can access system fonts is promoted as a
+virtue. The previous sections demonstrated that in practice this does not really
+free us from a name mess. Of course, when we use a really small \TEX\ tree, and
+system fonts only, there is not much that can go wrong, but when you have extra
+fonts installed there can be clashes.
+
+We're better off with filenames than we were in former times when operating
+systems and media forced distributors to stick to 8 characters in filenames. But
+that does not guarantee that today's shipments are more consistent. And as there
+are still some limitations in the length of fontnames, obscure names will be with
+us for a long time to come.

+\startchapter[title={Glocal assignments}]
+
+Here is a nice puzzle. Say that you do this:
+
+\starttyping
+\def\test{local} \test
+\stoptyping
+
+What will get typeset? Right, you'll get \type {local}. Now take this:
+
+\startbuffer
+\bgroup
+  \def \test {local}[\test]
+  \xdef\test{global}[\test]
+  \def \test {local}[\test]
+\egroup
+                    [\test]
+\stopbuffer
+
+\typebuffer
+
+Will you get:
+
+\starttyping
+[local] [local] [local] [global]
+\stoptyping
+
+or will it be:
+
+\starttyping
+[local] [global] [local] [global]
+\stoptyping
+
+Without knowing \TEX, there are good reasons for getting either of them: is a
+global assignment global only i.e.\ does it reach over the group(s) or is it
+global and local at the same time? The answer is that the global definitions also
+happens to be a local one, so the second line is what we get.
+
+Something similar happens with registers, like counters:
+
+\startbuffer
+\newcount\democount
+\bgroup
+         \democount 1[\the\democount]
+  \global\democount 2[\the\democount]
+         \democount 1[\the\democount]
+\egroup
+                     [\the\democount]
+\stopbuffer
+
+\typebuffer
+
+We get: {\tttf\getbuffer\removeunwantedspaces}, so this is
+consistent with macros. But how about boxes?
+
+\startbuffer
+\bgroup
+         \setbox0\hbox {local}[\copy0:\the\wd0]
+  \global\setbox0\hbox{global}[\copy0:\the\wd0]
+         \setbox0\hbox {local}[\copy0:\the\wd0]
+\egroup
+                              [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+Again, this is consistent, so let's do some manipulation:
+
+\startbuffer
+\bgroup
+         \setbox0\hbox{local}         \wd0=6em [\copy0:\the\wd0]
+  \global\setbox0\hbox{global} \global\wd0=5em [\copy0:\the\wd0]
+         \setbox0\hbox{local}         \wd0=6em [\copy0:\the\wd0]
+\egroup
+                                               [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+Right, no surprise here, but \unknown
+
+\startbuffer
+\bgroup
+         \setbox0\hbox{local}  \wd0=6em [\copy0:\the\wd0]
+  \global\setbox0\hbox{global} \wd0=5em [\copy0:\the\wd0]
+         \setbox0\hbox{local}  \wd0=6em [\copy0:\the\wd0]
+\egroup
+                                        [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+See the difference? There is none. The second width assignment is applied to the
+global box.
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+So how about this then:
+
+\startbuffer
+\bgroup
+         \setbox0\hbox{local}  \wd0=6em [\copy0:\the\wd0]
+  \global\setbox0\hbox{global}          [\copy0:\the\wd0]
+         \setbox0\hbox{local}  \wd0=6em [\copy0:\the\wd0]
+\egroup
+                                        [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+Is this what you expect?
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+So, in the case of boxes, an assignment to a box dimension is applied to the last
+instance of the register, and the global nature is kind of remembered. Inside a
+group, registers that are accessed are pushed on a stack and the assignments are
+applied to the one on the stack and when no local box is assigned, the one at the
+outer level gets the treatment. You can also say that a global box is unreachable
+once a local instance is used. \footnote {The code that implements \type
+{\global\setbox} actually removes all intermediate boxes.}
+
+\startbuffer
+\setbox0\hbox{outer} [\copy0:\the\wd0]
+\bgroup
+            \wd0=6em [\copy0:\the\wd0]
+\egroup
+                     [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+It works as expected when we use local boxes after such an assignment:
+
+\startbuffer
+\setbox0\hbox{outer}           [\copy0:\the\wd0]
+\bgroup
+                      \wd0=6em [\copy0:\the\wd0]
+  \setbox0\hbox{inner (local)} [\copy0:\the\wd0]
+\egroup
+                               [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+Interestingly in practice this is natural enough not to get noticed. Also, as the
+\TEX book explicitly mentions that one should not mix local and global usage, not
+many users will do that. For instance the scratch registers 0, 2, 4, 6 and 8 are
+often used locally while 1, 3, 5, 7 and 9 are supposedly used global. The
+argument for doing this is that it does not lead to unwanted stack build-up, but
+the last examples given here provide another good reason. Actually, global
+assignments happen seldom in macro packages, at least compared to local ones.
+
+In \LUATEX\ we can also access boxes at the \LUA\ end. We can for instance change
+the width as follows:
+
+\startbuffer
+\bgroup
+         \setbox0\hbox{local}
+         \ctxlua{tex.box[0].width = tex.sp("6em")} [\copy0:\the\wd0]
+  \global\setbox0\hbox{global}
+         \ctxlua{tex.box[0].width = tex.sp("5em")} [\copy0:\the\wd0]
+         \setbox0\hbox{local}
+         \ctxlua{tex.box[0].width = tex.sp("6em")} [\copy0:\the\wd0]
+\egroup
+                                                   [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+This is consistent with the \TEX\ end:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+This is also true for:
+
+\startbuffer
+\bgroup
+         \setbox0\hbox{local}
+         \ctxlua{tex.box[0].width = tex.sp("6em")} [\copy0:\the\wd0]
+  \global\setbox0\hbox{global}                     [\copy0:\the\wd0]
+         \setbox0\hbox{local}
+         \ctxlua{tex.box[0].width = tex.sp("6em")} [\copy0:\the\wd0]
+\egroup
+                                                   [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+Which gives:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+The fact that a \type {\global} prefix is not needed for a global assignment at
+the \TEX\ end means that we don't need a special function at the \LUA\ end for
+assigning the width of a box. You won't miss it.
+
+There is one catch when coding at the \TEX\ end. Imagine this:
+
+\startbuffer
+\setbox0\hbox{local} [\copy0:\the\wd0]
+\bgroup
+  \wd0=6em           [\copy0:\the\wd0]
+\egroup
+                     [\copy0:\the\wd0]
+\stopbuffer
+
+\typebuffer
+
+In sync with what we told you will get:
+
+\startlines \tttf
+\getbuffer
+\stoplines
+
+However, this does not look that intuitive as the following:
+
+\startbuffer
+\setbox0\hbox{local} [\copy0:\the\wd0]
+\bgroup
+  \global\wd0=6em    [\copy0:\the\wd0]
+\egroup
+                     [\copy0:\the\wd0]
+\stopbuffer
+
+Here the global is redundant but it looks quite okay to put it there if only to
+avoid confusion. \footnote {I finally decided to remove some of the \type
+{\global} prefixes in my older code, but I must admit that I sometimes felt
+reluctant when doing it, so I kept a few.}

+
+\startsection[title={Introduction}]
+
+The Oriental \TEX\ project is one of the first and more ambitious users of
+\LUATEX. A major undertaking in this project is the making of a rather full
+features and complex font for typesetting Arabic. As the following text will show
+some Arabic, you might get the impression that I'm an expert but be warned that
+I'm far from that. But as Idris compensates this quite well the team has a lot of
+fun in figuring out how to achieve our goals using \OPENTYPE\ technology in
+combination with \LUATEX\ and \MKIV. A nice side effect of this is that we end up
+with some neat tricks in the \CONTEXT\ core.
+
+Before we come to some of these goodies, an example of Arabic is given that
+relates quite well to the project. It was first used at the euro\TEX\ 2009
+meeting. Take the following 6 shapes:
+
+\starttabulate[|c|c|c|c|c|c|]
+\NC \ArabicFontFull ل \NC \ArabicFontFull و \NC \ArabicFontFull ا \NC \ArabicFontFull ت \NC \ArabicFontFull ي \NC \ArabicFontFull خ \NC \NR
+\NC \type{l} \NC \type{w} \NC \type{ā} \NC \type{t} \NC \type{ī} \NC \type{kh} \NC \NR
+\stoptabulate
+
+With these we can make the name \LUATEX\ and as we use a nice script we can
+forget about the lowered~E. Putting these characters in sequence is not enough as
+Arabic typesetting has to mimick the subtle aspects of scribes.
+
+In Latin scripts we have mostly one|-|to|-|one and many|-|to|-|one substitutions.
+These can happen in sequence which in in practice boils down to multiple passes
+over the stream of characters. In this process sometimes surrounding characters
+(or shapes) play a role, for instance ligatures are not always wanted and their
+coming into existence might depend on neighbouring characters. In some cases
+glyphs have to be (re)positioned relative to each other. While in Latin scripts
+the number of substitutions and positioning is not that large but in advanced
+Arabic fonts it can be pretty extensive.
+
+With \OPENTYPE\ we have some machinery available, so we try to put as much logic
+in the font as possible. However, in addition we have some dedicated optimizing
+routines. The whole process is split into a couple if stages.
+
+The so called First|-|Order Analysis puts a given character into isolated,
+initial, middle, or final state. Next, the Second|-|Order Analysis looks at the
+characters and relates this state to what characters precede or succeed it. Based
+on that state we do character substitutions. There can be multiple analysis and
+replacements in sequence. We can do some simple aesthetic stretching and
+additional related replacements. We need to attach identity marks and vowels in
+proper but nice looking places. In most cases we're then done. Contrary to other
+fonts we don't use many ligatures but compose characters.
+
+The previous steps already give reasonable results and implementing it also
+nicely went along with the development of \LUATEX\ and \CONTEXT\ \MKIV. Currently
+we're working on extending and perfecting the font to support what we call
+Third|-|Order Contextual Analysis. This boils down to an interplay between the
+paragraph builder and additional font features. In order to get pleasing spacing
+we apply further substitutions, this time with wider or narrower shapes. When
+this is done we need to reattach identity marks and vowels. Optionally we can
+apply \HZ\ like stretching as a finishing touch but so far we didn't follow that
+route yet.
+
+So, let's see how we can typeset the word \LUATEX\ in Arabic using some of these
+techniques.
+
+\startlines
+no order (kh ī t ā w [u] l)\hfilll {\righttoleft\ArabicFontNone لُواتيخ}
+first order \hfilll {\subff{husayni-first-order}\righttoleft\ArabicFontFull لُواتيخ}
+second order \hfilll {\righttoleft\ArabicFontFull لُواتيخ}
+second order (Jiim-stacking) \hfilll {\addff{husayni-stack-jiim-multi-level}\righttoleft\ArabicFontFull لُواتيخ}
+minimal stretching \hfilll {\addff{husayni-minimal-stretching}\righttoleft\ArabicFontFull لُواتيخ}
+maximal stretching (level 3) \hfilll {\addff{husayni-maximal-stretching}\righttoleft\ArabicFontFull لُواتيخ}
+chopped letter khaa (for e.g.\ underlining) \hfilll {\addff{husayni-chop-haa}\righttoleft\ArabicFontFull لُواتيخ}
+\stoplines
+
+As said, this font is quite complex in the sense that it has many features and
+associated lookups. In addition to the usual features we have stylistic and
+justification variants. As these are not standardized (after all, each font can
+have its own look and feel and associated treatments) we store some information
+in the goodies files that ship with this font.
+
+\startbuffer[stylistics]
+\startluacode
+  local goodies = fonts.goodies.load("husayni")
+  local stylistics = goodies and goodies.stylistics
+  if stylistics then
+    local col, row, type = context.NC, context.NR, context.type
+    context.starttabulate { "|l|pl|" }
+    col() context("feature") col() context("meaning") col() row()
+    for feature, meaning in table.sortedpairs(stylistics) do
+      col() type(feature) col() type(meaning) col() row()
+    end
+    context.stoptabulate()
+  end
+\stopluacode
+\stopbuffer
+
+\getbuffer[stylistics]
+
+It is highly unlikely that a user will remember all these features, which is why
+there will be a bunch of predefined combinations. These are internalized as
+follows:
+
+\startbuffer[featuresets]
+\startluacode
+  local goodies = fonts.goodies.load("husayni")
+  local featuresets = goodies and goodies.featuresets
+  if featuresets then
+    local col, row, type = context.NC, context.NR, context.type
+    context.starttabulate { "|l|pl|" }
+    col() context("featureset") col() context("definitions") col() row()

+      for k, v in table.sortedpairs(definitions) do
+        type(string.format("%s=%s",k,tostring(v)))
+        context.quad()
+      end
+      col() row()

+    context.stoptabulate()
+  end

+\startsection[title={Color}]
+
+One of the objectives of the oriental \TEX\ project is to bring color to typeset
+Arabic. When Idris started making samples with much manual intervention it was
+about time to figure out if it could be supported by a bit of \LUA\ code.
+
+As the colorization concerns classes of glyphs (like vowels) this is something
+that can best be done after all esthetics have been sorted out. Because things
+like coloring are not part of font technology and because we don't want to misuse
+the \OPENTYPE\ feature mechanisms for that, the solution lays in an extra file
+that describes these goodies.
+
+\startbuffer[goodies-1]
+\definefontfeature
+  [husayni-colored]
+  [goodies=husayni,
+   colorscheme=default,
+   featureset=default]
+\stopbuffer

+\stop
+\stopbuffer
+
+\getbuffer[goodies-1,goodies-2]
+
+The second and third of these three lines have colored vowels and identity marks.
+So how did we get the colors? There are actually two mechanisms involved in this:
+
+\startitemize[packed]
+\startitem we need to associate colorschemes with classed of glyphs \stopitem
+\startitem we need to be able to turn on and off coloring \stopitem
+\stopitemize
+
+The first is done by loading goodies and selecting a colorscheme:
+
+\typebuffer[goodies-1]
+
+Turning on and off coloring is done with two commands (we might provide a proper
+environment for this) as shown in:
+
+\typebuffer[goodies-2]
+
+If you look closely at the feature definition you'll notice that we also choose a
+default featureset. For most (latin) fonts the regular feature definitions are
+convenient, but for fonts that are used for Arabic there are preferred
+combinations of features as there can be many.
+
+Currently the font we use here has the following colorschemes:
+
+\startbuffer[colorschemes]
+\startluacode
+  local goodies = fonts.goodies.load("husayni")
+  local colorschemes = goodies and goodies.colorschemes
+  if colorschemes then
+    local col, row, type = context.NC, context.NR, context.type
+    context.starttabulate { "|l|pl|" }
+    col() context("colorscheme") col() context("numbers") col() row()
+    for colorscheme, numbers in table.sortedpairs(colorschemes) do
+      col() type(colorscheme) col()
+      for i=1,#numbers do
+        type(i)
+        context.quad()
+      end
+      col() row()

+    context.stoptabulate()
+  end

+\startsection[title={The goodies file}]
+
+In principle a goodies files can contain anuy data that makes sense but in order
+to be useable some entries have a prescribed structure. A goodies file looks as
+follows:

+\stoptyping
+
+We already saw the list of special features and these are defined in the \type
+{stylistics} stable. In this document, that list was typeset using the following
+(hybrid) code:
+
+\typebuffer[stylistics]
+
+The table with colorscheme that we showed is generated with:
+
+\getbuffer[colorschemes]
+
+In a similar fashion we typeset the featuresets:
+
+\typebuffer[featuresets]
+
+The unprocessed \type {featuresets} table can contain one or more
+named sets and each set can be a mixture of tables and key value
+pairs. Say that we have:
+
+\starttyping
+  default = {
+    kern = "yes", { ss01 = "yes" }, { ss02 = "yes" }, "mark"
+  }
+\stoptyping
+
+Given the previous definition, the order of processing is as follows.
+
+\startitemize[packed,n]
+\startitem \type {{ ss01 = "yes" }} \stopitem
+\startitem \type {{ ss02 = "yes" }} \stopitem
+\startitem \type {mark} (set to \type {"yes"}) \stopitem
+\startitem \type {kern = "yes"} \stopitem
+\stopitemize
+
+So, first we process the indexed part if the list, and next the hash. Already set
+values are not set again. The advantage of using a \LUA\ table is that you can
+simplify definitions. Before we return the table we can define local variables,
+like:
+
+\starttyping
+local one = { ss01 = "yes" }
+local two = { ss02 = "yes" }
+local pos = { kern = "yes", mark = "yes" }
+\stoptyping
+
+and use them in:
+
+\starttyping
+default = {
+  one, two, pos
+}
+\stoptyping
+
+That way we we can conveniently define all kind of interesting combinations
+without the need for many repetitive entries.
+
+The \type {colorsets} table has named subtables that are (currently) indexed by
+number. Each number is associated with a color (at the \TEX\ end) and is coupled
+to a list of glyphs. As you can see here, we use the name of the glyph. We prefer
+this over an index (that can change during development of the font). We cannot
+use \UNICODE\ points as many such glyphs are just variants and have no unique
+code.

+
+The ultimate goal of the Oriental \TEX\ project is to improve the look and feel
+of a paragraph. Because \TEX\ does a pretty good job on breaking the paragraph
+into lines, and because complicating the paragraph builder is not a good idea, we
+finally settled on improving the lines that result from the par builder. This
+approach is rather close to what scribes do and the advanced Husayni font
+provides features that support this.
+
+In principle the current optimizer can replace character expansion but that would
+slow down considerably. Also, for that we first have to clean up the experimental
+\LUA\ based par builder.
+
+After several iterations the following approach was chosen.
+
+\startitemize
+
+\startitem
+    We typeset the paragraph with an optimal feature set. In our case this is
+    \type {husayni-default}.
+\stopitem
+
+\startitem
+    Next we define two sets of additional features: one that we can apply to
+    shrink words, and one that does the opposite.
+\stopitem
+
+\startitem
+    When the line has a badness we don't like, we either stepwise shrink words or
+    stretch them, depending on how bad things are.
+\stopitem
+
+\stopitemize
+
+The set that takes care of shrinking is defined as:
+
+\starttyping
+\definefontfeature
+  [shrink]
+  [husayni-default]
+  [flts=yes,js17=yes,ss05=yes,ss11=yes,ss06=yes,ss09=yes]
+\stoptyping
+
+Stretch has a few more variants:
+
+\starttyping
+\definefontfeature
+  [minimal_stretching]
+  [husayni-default]
+  [js11=yes,js03=yes]
+\definefontfeature
+  [medium_stretching]
+  [husayni-default]
+  [js12=yes,js05=yes]
+\definefontfeature
+  [maximal_stretching]
+  [husayni-default]
+  [js13=yes,js05=yes,js09=yes]
+\definefontfeature
+  [wide_all]
+  [husayni-default]
+  [js11=yes,js12=yes,js13=yes,js05=yes,js09=yes]
+\stoptyping
+
+Next we define a font solution:
+
+\starttyping
+\definefontsolution
+  [FancyHusayni]
+  [goodies=husayni,
+   less=shrink,
+   more={minimal_stretching,medium_stretching,maximal_stretching,wide_all}]
+\stoptyping
+
+Because these featuresets relate quite closely to the font design we don't use
+this way if defining but put the definitions in the goodies file:
+
+\startntyping
+    .....
+    featuresets = { -- here we don't have references to featuresets
+        default = {
+            default,
+        },
+        minimal_stretching = {
+            default, js11 = yes, js03 = yes,
+        },
+        medium_stretching = {
+            default, js12=yes, js05=yes,
+        },
+        maximal_stretching= {
+            default, js13 = yes, js05 = yes, js09 = yes,
+        },
+        wide_all = {
+            default, js11 = yes, js12 = yes, js13 = yes, js05 = yes, js09 = yes,
+        },
+        shrink = {
+            default, flts = yes, js17 = yes, ss05 = yes, ss11 = yes, ss06 = yes, ss09 = yes,
+        },
+    },
+    solutions = { -- here we have references to featuresets, so we use strings!
+        experimental = {
+            less = { "shrink" },
+            more = { "minimal_stretching", "medium_stretching", "maximal_stretching", "wide_all" },
+        },
+    },
+    .....
+\stopntyping

+
+This mechanism is somewhat experimental as is the (user) interface. It is also
+rather slow compared to normal processing. There is room for improvement but I
+will do that when other components are more stable so that simple variants (that
+we can use here) can be derived.
+
+When criterium~0 used above is changed into for instance~5 processing is faster.
+When you enable a preroll processing is more time consuming. Examples of settings

+
+\starttyping
+\setupfontsolutions[method={preroll,normal},criterium=2]
+\setupfontsolutions[method={preroll,random},criterium=5]
+\setupfontsolutions[method=reverse,criterium=8]
+\setupfontsolutions[method=random,criterium=2]

+
+Using a preroll is slower because it first tries all variants and then settles

+
+\stopsection
+
+\startsection[title={Filenames and properties}]
+
+As filenames and properties of fonts are somewhat of an inconsistent mess, we can

+\startsection [title={Variants}]
+
+After using \TEX\ for a while you get accustomed to one of its interesting
+concepts: grouping. Programming languages like \PASCAL\ and \MODULA\ have
+keywords \type {begin} and \type {end}. So, one can say:
+
+\starttyping
+if test then begin
+    print_bold("test 1")
+    print_bold("test 2")
+end
+\stoptyping
+
+Other languages provide a syntax like:
+
+\starttyping
+if test {
+    print_bold("test 1")
+    print_bold("test 2")
+}
+\stoptyping
+
+So, in those languages the \type {begin} and \type {end} and|/|or the curly
+braces define a \quote {group} of statements. In \TEX\ on the other hand we have:
+
+\starttyping
+test \begingroup \bf test \endgroup test
+\stoptyping
+
+Here the second \type {test} comes out in a bold font and the switch to bold
+(basically a different font is selected) is reverted after the group is closed.
+So, in \TEX\ grouping deals with scope and not with grouping things together.
+
+In other languages it depends on the language of locally defined variables are
+visible afterwards but in \TEX\ they're really local unless a \type {\global}
+prefix (or one of the shortcuts) is used.
+
+In languages like \LUA\ we have constructs like:
+
+\starttyping
+for i=1,100 do
+    local j = i + 20
+    ...
+end
+\stoptyping
+
+Here \type {j} is visible after the loop ends unless prefixed by \type {local}.
+Yet another example is \METAPOST:
+
+\starttyping
+begingroup ;
+    save n ; numeric n ; n := 10 ;
+    ...
+endgroup ;
+\stoptyping
+
+Here all variables are global unless they are explicitly saved inside a group.
+This makes perfect sense as the resulting graphic also has a global (accumulated)
+property. In practice one rarely needs grouping, contrary to \TEX\ where one
+really wants to keep changes local, if only because document content is so
+unpredictable that one never knows when some change in state happens.
+
+In principle it is possible to carry over information across a group boundary.
+Consider this somewhat unrealistic example:
+
+\starttyping
+\begingroup
+    \leftskip 10pt
+    \begingroup
+        ....
+        \advance\leftskip 10pt
+        ....
+    \endgroup
+\endgroup
+\stoptyping
+
+How do we carry the advanced leftskip over the group boundary without using a
+global assignment which could have more drastic side effects? Here is the trick:
+
+\starttyping
+\begingroup
+    \leftskip 10pt
+    \begingroup
+        ....
+        \advance\leftskip 10pt
+        ....
+        \expandafter
+    \endgroup
+    \expandafter \leftskip \the\leftskip
+\endgroup
+\stoptyping
+
+This is typical the kind of code that gives new users the creeps but normally
+they never have to do that kind of coding. Also, that kind of tricks assumes that
+one knows how many groups are involved.
+
+\stopsection
+
+\startsection [title={Implication}]
+
+What does this all have to do with \LUATEX\ and \MKIV ? The user interface of
+\CONTEXT\ provide lots of commands like:
+
+\starttyping
+\setupthis[style=bold]
+\setupthat[color=green]
+\stoptyping
+
+Most of them obey grouping. However, consider a situation where we use \LUA\ code
+to deal with some aspect of typesetting, for instance numbering lines or adding
+ornamental elements to the text. In \CONTEXT\ we flag such actions with
+attributes and often the real action takes place a bit later, for instance when a
+paragraph or page becomes available.
+
+A comparable pure \TEX\ example is the following:
+
+\starttyping
+{test test \bf test \leftskip10pt test}
+\stoptyping
+
+Here the switch to bold happens as expected but no leftskip of 10pt is applied.
+This is because the set value is already forgotten when the paragraph is actually
+typeset. So in fact we'd need:
+
+\starttyping
+{test test \bf test \leftskip10pt test \par}
+\stoptyping
+
+Now, say that we have:
+
+\starttyping
+{test test test \setupflag[option=1] \flagnexttext test}
+\stoptyping
+
+We flag some text (using an attribute) and expect it to get a treatment where
+option~1 is used. However, the real action might take place when \TEX\ deals with
+the paragraph or page and by that time the specific option is already forgotten
+or it might have gotten another value. So, the rather natural \TEX\ grouping does
+not work out that well in a hybrid situation.
+
+As the user interface assumes a consistent behaviour we cannot simply make these
+settings global even if this makes much sense in practice. One solution is to
+carry the information with the flagged text i.e.\ associate it somehow in the
+attribute's value. Of course, as we never know in advance when this information
+is used, this might result in quite some states being stored persistently.
+
+A side effect of this \quote {problem} is that new commands might get suboptimal
+user interfaces (especially inheritance or cloning of constructs) that are
+somewhat driven by these \quote {limitations}. Of course we may wonder if the end
+user will notice this.
+
+To summarize this far, we have three sorts of grouping to deal with:
+
+\startitemize[item]
+
+\startitem
+    \TEX's normal grouping model limits its scope to the local situation and
+    normally has only direct and local consequences. We cannot carry information
+    over groups.
+\stopitem
+
+\startitem
+    Some of \TEX's properties are applied later, for instance when a paragraph or
+    page is typeset and in order to make \quote {local} changes effective, the
+    user needs to add explicit paragraph ending commands (like \type {\par} or
+    \type {\page}).
+\stopitem
+
+\startitem
+    Features dealt with asynchronously by \LUA\ are at that time unaware of
+    grouping and variables set that were active at the time the feature was
+    triggered so there we need to make sure that our settings travel with the
+    feature. There is not much that a user can do about it as this kind of
+    management has to be done by the feature itself.
+\stopitem
+
+\stopitemize
+
+\stopsection
+
+It is the third case that we will give an example of in the next section. We
+leave it up to the user if it gets noticed on the user interface.
+
+\startsection [title={An example}]
+
+A group of commands that has been reimplemented using a hybrid solution is
+underlining or more generic: bars. Just take a look at the following examples and
+try to get an idea on how to deal with grouping. Keep in mind that:
+
+\startitemize[packed]
+\startitem
+    Colors are attributes and are resolved in the backend, so way after the
+    paragraph has been typeset.
+\stopitem
+\startitem
+    Overstrike is also handled by an attribute and gets applied in the backend as
+    well, before colors are applied.
+\stopitem
+\startitem
+    Nested overstrikes might have different settings.
+\stopitem
+\startitem
+    An overstrike rule either inherits from the text or has its own color
+    setting.
+\stopitem
+\stopitemize
+
+First an example where we inherit color from the text:
+
+\startbuffer
+\definecolor[myblue][b=.75]
+\definebar[myoverstrike][overstrike][color=]
+
+Test \myoverstrike{%
+    Test \myoverstrike{\myblue
+        Test \myoverstrike{Test}
+        Test}
+    Test}
+Test
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Because color is also implemented using attributes and processed later on we can
+access that information when we deal with the bar.
+
+The following example has its own color setting:
+
+\startbuffer
+\definecolor[myblue][b=.75]
+\definecolor[myred] [r=.75]
+\definebar[myoverstrike][overstrike][color=myred]
+
+Test \myoverstrike{%
+    Test \myoverstrike{\myblue
+        Test \myoverstrike{Test}
+        Test}
+    Test}
+Test
+\stopbuffer
+
+\typebuffer \getbuffer
+
+See how we can color the levels differently:
+
+\startbuffer
+\definecolor[myblue] [b=.75]
+\definecolor[myred]  [r=.75]
+\definecolor[mygreen][g=.75]
+
+\definebar[myoverstrike:1][overstrike][color=myblue]
+\definebar[myoverstrike:2][overstrike][color=myred]
+\definebar[myoverstrike:3][overstrike][color=mygreen]
+
+Test \myoverstrike{%
+    Test \myoverstrike{%
+        Test \myoverstrike{Test}
+        Test}
+    Test}
+Test
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Watch this:
+
+\startbuffer
+\definecolor[myblue] [b=.75]
+\definecolor[myred]  [r=.75]
+\definecolor[mygreen][g=.75]
+
+\definebar[myoverstrike][overstrike][max=1,dy=0,offset=.5]
+\definebar[myoverstrike:1][myoverstrike][color=myblue]
+\definebar[myoverstrike:2][myoverstrike][color=myred]
+\definebar[myoverstrike:3][myoverstrike][color=mygreen]
+
+Test \myoverstrike{%
+    Test \myoverstrike{%
+        Test \myoverstrike{Test}
+        Test}
+    Test}
+Test
+\stopbuffer
+
+\typebuffer \getbuffer
+
+It this the perfect user interface? Probably not, but at least it keeps the
+implementation quite simple.
+
+The behaviour of the \MKIV\ implementation is roughly the same as in \MKII,
+although now we specify the dimensions and placement in terms of the ratio of the
+x-height of the current font.
+
+\startbuffer
+Test \overstrike{Test \overstrike{Test \overstrike{Test} Test} Test} Test \blank
+Test \underbar  {Test \underbar  {Test \underbar  {Test} Test} Test} Test \blank
+Test \overbar   {Test \overbar   {Test \overbar   {Test} Test} Test} Test \blank
+Test \underbar  {Test \overbar   {Test \overstrike{Test} Test} Test} Test \blank
+\stopbuffer
+
+\typebuffer \getbuffer
+
+As an extra this mechanism can also provide simple backgrounds. The normal
+background mechanism uses \METAPOST\ and the advantage is that we can use
+arbitrary shapes but it also carries some limitations. When the development of
+\LUATEX\ is a bit further along the road I will add the possibility to use
+\METAPOST\ shapes in this mechanism.
+
+Before we come to backgrounds, first take a look at these examples:
+
+\startbuffer
+\startbar[underbar]  \input zapf \stopbar \blank
+\startbar[underbars] \input zapf \stopbar \blank
+\stopbuffer
+
+\typebuffer \getbuffer
+
+First notice that it is no problem to span multiple lines and that hyphenation is
+not influenced at all. Second you can see that continuous rules are also
+possible. From such a continuous rule to a background is a small step:
+
+\startbuffer
+\definebar
+  [backbar]
+  [offset=1.5,rulethickness=2.8,color=blue,

+
+The following example code looks messy but this has to do with the fact that we
+want properly spaced sample injection.
+
+\startbuffer
+from here
+    \startcolor[white]%
+        \startbar[backbar]%

+    \stopbar
+\space till here
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Watch how we can use the order to hide content. By default rules are drawn on top
+of the text.
+
+Nice effects can be accomplished with transparencies:
+
+\startbuffer
+\definecolor [tblue] [b=.5,t=.25,a=1]
+\setupbars [backbar] [color=tblue]
+\setupbars [forebar] [color=tblue]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We use as example:
+
+\startbuffer[sample]
+from here {\white \backbar{test test}
+    \backbar {nested nested} \backbar{also also}} till here
+from here {\white \backbar{test test
+    \backbar {nested nested}          also also}} till here
+from here {\white \backbar{test test
+    \backbar {nested nested}          also also}} till here
+\stopbuffer
+
+\typebuffer[sample] \getbuffer[sample]
+
+The darker nested variant is just the result of two transparent bars on top of
+each other. We can limit stacking, for instance:
+
+\startbuffer
+\setupbars[backbar][max=1]
+\setupbars[forebar][max=1]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This gives
+
+\getbuffer[sample]
+
+There are currently some limitations that are mostly due to the fact that we use
+only one attribute for this feature and a change in value triggers another
+handling. So, we have no real nesting here.
+
+The default commands are defined as follows:
+
+\starttyping
+\definebar[overstrike]  [method=0,dy= 0.4,offset= 0.5]
+\definebar[underbar]    [method=1,dy=-0.4,offset=-0.3]
+\definebar[overbar]     [method=1,dy= 0.4,offset= 1.8]
+
+\definebar[overstrikes] [overstrike] [continue=yes]
+\definebar[underbars]   [underbar]   [continue=yes]
+\definebar[overbars]    [overbar]    [continue=yes]
+\stoptyping
+
+As the implementation is rather non|-|intrusive you can use bars
+almost everywhere. You can underbar a whole document but equally
+well you can stick to fooling around with for instance formulas.
+
+\startbuffer
+\definecolor [tred]   [r=.5,t=.25,a=1]
+\definecolor [tgreen] [g=.5,t=.25,a=1]
+\definecolor [tblue]  [b=.5,t=.25,a=1]
+
+\definebar [mathred]   [backbar] [color=tred]
+\definebar [mathgreen] [backbar] [color=tgreen]
+\definebar [mathblue]  [backbar] [color=tblue]
+
+\startformula
+    \mathred{e} = \mathgreen{\white mc} ^ {\mathblue{\white e}}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+We get:
+
+\getbuffer
+
+We started this chapter with some words on grouping. In the examples you see no
+difference between adding bars and for instance applying color. However you need
+to keep in mind that this is only because behind the screens we keep the current
+settings along with the attribute. In practice this is only noticeable when you
+do lots of (local) changes to the settings. Take:
+
+\starttyping
+{test test test \setupbars[color=red] \underbar{test} test}
+\stoptyping
+
+This results in a local change in settings, which in turn will associate a new
+attribute to \type {\underbar}. So, in fact the following underbar becomes a
+different one than previous underbars. When the page is prepared, the unique
+attribute value will relate to those settings. Of course there are more
+mechanisms where such associations take place.
+
+\stopsection
+
+\startsection [title={More to come}]
+
+Is this all there is? No, as usual the underlying mechanisms can be used for
+other purposes as well. Take for instance inline notes:
+
+\startbuffer
+According to the wikipedia this is the longest English word:
+pneumonoultramicroscopicsilicovolcanoconiosis~\shiftup {other long
+words are pseudopseudohypoparathyroidism and
+flocci­nauci­nihili­pili­fication}. Of course in languages like Dutch and
+German we can make arbitrary long words by pasting words together.
+\stopbuffer
+
+\typebuffer
+
+This will produce:
+
+\getbuffer
+
+I wonder when users really start using such features.
+
+\stopsection
+
+\startsection [title={Summary}]
+
+Although under the hood the \MKIV\ bar commands are quite different from their
+\MKII\ counterparts users probably won't notice much difference at first sight.
+However, the new implementation does not interfere with the par builder and other
+mechanisms. Plus, it is configurable and it offers more functionality. However,
+as it is processed rather delayed, side effects might occur that are not
+foreseen.
+
+So, if you ever notice such unexpected side effects, you know where it might
+result from: what you asked for is processed much later and by then the
+circumstances might have changed. If you suspect that it relates to grouping
+there is a simple remedy: define a new bar command in the document preamble
+instead of changing properties mid|-|document. After all, you are supposed to
+separate rendering and content in the first place.

+\startchapter[title={Deeply nested notes}]
+
+\startsection [title={Introduction}]
+
+One of the mechanisms that is not on a users retina when he or she starts using
+\TEX\ is \quote {inserts}. An insert is material that is entered at one point but
+will appear somewhere else in the output. Footnotes for instance can be
+implemented using inserts. You create a reference symbol in the running text and
+put note text at the bottom of the page or at the end of a chapter or document.
+But as you don't want to do that moving around of notes yourself \TEX\ provides
+macro writers with the inserts mechanism that will do some of the housekeeping.
+Inserts are quite clever in the sense that they are taken into account when \TEX\
+splits off a page. A single insert can even be split over two or more pages.
+
+Other examples of inserts are floats that move to the top or bottom of the page
+depending on requirements and|/|or available space. Of course the macro package
+is responsible for packaging such a float (for instance an image) but by finally
+putting it in an insert \TEX\ itself will attempt to deal with accumulated floats
+and help you move kept over floats to following pages. When the page is finally
+assembled (in the output routine) the inserts for that page become available and
+can be put at the spot where they belong. In the process \TEX\ has made sure that
+we have the right amount of space available.
+
+However, let's get back to notes. In \CONTEXT\ we can have many variants of them,
+each taken care of by its own class of inserts. This works quite well, as long as
+a note is visible for \TEX\ which means as much as: ends up in the main page
+flow. Consider the following situation:
+
+\starttyping
+before \footnote{the note} after
+\stoptyping
+
+When the text is typeset, a symbol is placed directly after the word \quote
+{before} and the note itself ends up at the bottom of the page. It also works
+when we wrap the text in an horizontal box:
+
+\starttyping
+\hbox{before \footnote{the note} after}
+\stoptyping
+
+But it fails as soon as we go further:
+
+\starttyping
+\hbox{\hbox{before \footnote{the note} after}}
+\stoptyping
+
+Here we get the reference but no note. This also fails:
+
+\starttyping
+\vbox{before \footnote{the note} after}
+\stoptyping
+
+Can you imagine what happens if we do the following?
+
+\starttyping
+\starttabulate
+\NC knuth \NC test \footnote{knuth} \input knuth \NC \NR
+\NC tufte \NC test \footnote{tufte} \input tufte \NC \NR
+\NC ward  \NC test \footnote{ward}  \input ward  \NC \NR
+\stoptabulate
+\stoptyping
+
+This mechanism uses alignments as well as quite some boxes. The paragraphs are
+nicely split over pages but still appear as boxes to \TEX\ which make inserts
+invisible. Only the three symbols would remain visible. But because in \CONTEXT\
+we know when notes tend to disappear, we take some provisions, and contrary to
+what you might expect the notes actually do show up. However, they are flushed in
+such a way that they end up on the page where the table ends. Normally this is no
+big deal as we will often use local notes that end up at the end of the table
+instead of the bottom of the page, but still.
+
+The mechanism to deal with notes in \CONTEXT\ is somewhat complex at the source
+code level. To mention a few properties we have to deal with:
+
+\startitemize[packed]
+\startitem Notes are collected and can be accessed any time. \stopitem
+\startitem Notes are flushed either directly or delayed. \stopitem
+\startitem Notes can be placed anywhere, any time, perhaps in subsets. \stopitem
+\startitem Notes can be associated to lines in paragraphs. \stopitem
+\startitem Notes can be placed several times with different layouts. \stopitem
+\stopitemize
+
+So, we have some control over flushing and placement, but real synchronization
+between for instance table entries having notes and the note content ending up on
+the same page is impossible.
+
+In the \LUATEX\ team we have been discussing more control over inserts and we
+will definitely deal with that in upcoming releases as more control is needed for
+complex multi|-|column document layouts. But as we have some other priorities
+these extensions have to wait.
+
+As a prelude to them I experimented a bit with making these deeply buried inserts
+visible. Of course I use \LUA\ for this as \TEX\ itself does not provide the kind
+of access we need for this kind of of manipulations.
+
+\stopsection
+
+\startsection [title={Deep down inside}]
+
+Say that we have the following boxed footnote. How does that end up in \LUATEX ?
+
+\starttyping
+\vbox{a\footnote{b}c}
+\stoptyping
+
+Actually it depends on the macro package but the principles remain the same. In
+\LUATEX\ 0.50 and the \CONTEXT\ version used at the time of this writing we get
+(nested) linked list that prints as follows:
+
+\starttyping
+<node   26 <  862 >  nil : vlist 0>
+  <node  401 <  838 >  507 : hlist 1>
+    <node   30 <  611 >  580 : whatsit 6>
+    <node  611 <  580 >  493 : hlist 0>
+    <node  580 <  493 >  653 : glyph 256>
+    <node  493 <  653 >  797 : penalty 0>
+    <node  653 <  797 >  424 : kern 1>
+    <node  797 <  424 >  826 : hlist 2>
+      <node  445 <  563 >  nil : hlist 2>
+        <node  420 <  817 >  821 : whatsit 35>
+        <node  817 <  821 >  nil : glyph 256>
+    <node  507 <  826 > 1272 : kern 1>
+    <node  826 < 1272 > 1333 : glyph 256>
+    <node 1272 < 1333 >  830 : penalty 0>
+    <node 1333 <  830 >  888 : glue 15>
+    <node  830 <  888 >  nil : glue 9>
+  <node  838 <  507 >  nil : ins 131>
+\stoptyping
+
+The numbers are internal references to the node memory pool. Each line represents
+a node:
+
+\starttyping
+<node prev_index < index > next_index : type subtype>
+\stoptyping
+
+The whatsits carry directional information and the deeply nested hlist is the
+note symbol. If we forget about whatsits, kerns and penalties, we can simplify
+this listing to:
+
+\starttyping
+<node   26 <  862 >  nil : vlist 0>
+  <node  401 <  838 >  507 : hlist 1>
+    <node  580 <  493 >  653 : glyph 256>
+    <node  797 <  424 >  826 : hlist 2>
+      <node  445 <  563 >  nil : hlist 2>
+        <node  817 <  821 >  nil : glyph 256>
+    <node  826 < 1272 > 1333 : glyph 256>
+  <node  838 <  507 >  nil : ins 131>
+\stoptyping
+
+So, we have a vlist (the \type {\vbox}), which has one line being a hlist. Inside
+we have a glyph (the \quote{a}) followed by the raised symbol (the
+\quote{\high{1}}) and next comes the second glyph (the \quote{b}). But watch how
+the insert ends up at the end of the line. Although the insert will not show up
+in the document, it sits there waiting to be used. So we have:
+
+\starttyping
+<node   26 <  862 >  nil : vlist 0>
+  <node  401 <  838 >  507 : hlist 1>
+  <node  838 <  507 >  nil : ins 131>
+\stoptyping
+
+but we need:
+
+\starttyping
+<node   26 <  862 >  nil : vlist 0>
+  <node  401 <  838 >  507 : hlist 1>
+<node  838 <  507 >  nil : ins 131>
+\stoptyping
+
+Now, we could use the fact that inserts end up at the end of the line, but as we
+need to recursively identify them anyway, we cannot actually use this fact to
+optimize the code.
+
+In case you wonder how multiple inserts look like, here is an example:
+
+\starttyping
+\vbox{a\footnote{b}\footnote{c}d}
+\stoptyping
+
+This boils down to:
+
+\starttyping
+<node   26 < 1324 >  nil : vlist 0>
+  <node  401 < 1348 >  507 : hlist 1>
+  <node 1348 <  507 >  457 : ins 131>
+  <node  507 <  457 >  nil : ins 131>
+\stoptyping
+
+In case you wonder what more can end up at the end, vertically adjusted material
+(\type {\vadjust}) as well as marks (\type {\mark}) also get that treatment.
+
+\starttyping
+\vbox{a\footnote{b}\vadjust{c}\footnote{d}e\mark{f}}
+\stoptyping
+
+As you see, we start with the line itself, followed by a mixture of inserts and
+vertically adjusted content (that will be placed before that line). This trace
+also shows the list 2~levels deep.
+
+\starttyping
+<node   26 < 1324 >  nil : vlist 0>
+  <node  401 < 1348 >  507 : hlist 1>
+  <node 1348 <  507 >  862 : ins 131>
+  <node  507 <  862 >  240 : hlist 1>
+  <node  862 <  240 > 2288 : ins 131>
+  <node  240 < 2288 >  nil : mark 0>
+\stoptyping
+
+Currently vadjust nodes have the same subtype as an ordinary hlist but in
+\LUATEX\ versions beyond 0.50 they will have a dedicated subtype.
+
+We can summarize the pattern of one \quote {line} in a vertical list as:
+
+\starttyping
+[hlist][insert|mark|vadjust]*[penalty|glue]+
+\stoptyping
+
+In case you wonder what happens with for instance specials, literals (and other
+whatits): these end up in the hlist that holds the line. Only inserts, marks and
+vadjusts migrate to the outer level, but as they stay inside the vlist, they are
+not visible to the page builder unless we're dealing with the main vertical list.
+Compare:
+
+\starttyping
+this is a regular paragraph possibly with inserts and they
+will be visible as the lines are appended to the main
+vertical list \par
+\stoptyping
+
+with:
+
+\starttyping
+but \vbox {this is a nested paragraph where inserts will
+stay with the box} and not migrate here \par
+\stoptyping
+
+So much for the details; let's move on the how we can get
+around this phenomenon.
+
+\stopsection
+
+\startsection [title={Some \LUATEX\ magic}]
+
+The following code is just the first variant I made and \CONTEXT\ ships with a
+more extensive variant. Also, in \CONTEXT\ this is part of a larger suite of
+manipulative actions but it does not make much sense (at least not now) to
+discuss this framework here.
+
+We start with defining a couple of convenient shortcuts.
+
+\starttyping
+local hlist = node.id('hlist')
+local vlist = node.id('vlist')
+local ins   = node.id('ins')
+\stoptyping
+
+We can write a more compact solution but splitting up the functionality better
+shows what we're doing. The main migration function hooks into the callback \type
+{build_page}. Contrary to other callbacks that do phases in building lists and
+pages this callback does not expect the head of a list as argument. Instead, we
+operate directly on the additions to the main vertical list which is accessible
+as \type {tex.lists.contrib_head}.
+
+\starttyping
+local deal_with_inserts -- forward reference
+
+local function migrate_inserts(where)
+    local current = tex.lists.contrib_head
+    while current do
+        local id = current.id
+        if id == vlist or id == hlist then
+            current = deal_with_inserts(current)
+        end
+        current = current.next
+    end
+end
+
+callback.register('buildpage_filter',migrate_inserts)
+\stoptyping
+
+So, effectively we scan for vertical and horizontal lists and deal with embedded
+inserts when we find them. In \CONTEXT\ the migratory function is just one of the
+functions that is applied to this filter.
+
+We locate inserts and collect them in a list with \type {first} and \type {last}
+as head and tail and do so recursively. When we have run into inserts we insert
+them after the horizontal or vertical list that had embedded them.
+
+\starttyping
+local locate -- forward reference
+
+deal_with_inserts = function(head)
+    local h, first, last = head.list, nil, nil
+    while h do
+        local id = h.id
+        if id == vlist or id == hlist then
+            h, first, last = locate(h,first,last)
+        end
+        h = h.next
+    end
+    if first then
+        local n = head.next
+        head.next = first
+        first.prev = head
+        if n then
+            last.next = n
+            n.prev = last
+        end
+        return last
+    else
+        return head
+    end
+end
+\stoptyping
+
+The \type {locate} function removes inserts and adds them to a new list, that is
+passed on down in recursive calls and eventually is returned back to the caller.
+
+\starttyping
+locate = function(head,first,last)
+    local current = head
+    while current do
+        local id = current.id
+        if id == vlist or id == hlist then
+            current.list, first, last = locate(current.list,first,last)
+            current = current.next
+        elseif id == ins then
+            local insert = current
+            head, current = node.remove(head,current)
+            insert.next = nil
+            if first then
+                insert.prev = last
+                last.next = insert
+            else
+                insert.prev = nil
+                first = insert
+            end
+            last = insert
+        else
+            current = current.next
+        end
+    end
+    return head, first, last
+end
+\stoptyping
+
+As we can encounter the content several times in a row, it makes sense to mark
+already processed inserts. This can for instance be done by setting an attribute.
+Of course one has to make sure that this attribute is not used elsewhere.
+
+\starttyping
+if not node.has_attribute(current,8061) then
+    node.set_attribute(current,8061,1)
+    current = deal_with_inserts(current)
+end
+\stoptyping
+
+or integrated:
+
+\starttyping
+local has_attribute = node.has_attribute
+local set_attribute = node.set_attribute
+
+local function migrate_inserts(where)
+    local current = tex.lists.contrib_head
+    while current do
+        local id = current.id
+        if id == vlist or id == hlist then
+            if has_attribute(current,8061) then
+                -- maybe some tracing message
+            else
+                set_attribute(current,8061,1)
+                current = deal_with_inserts(current)
+            end
+        end
+        current = current.next
+    end
+end
+
+callback.register('buildpage_filter',migrate_inserts)
+\stoptyping
+
+\stopsection
+
+\startsection [title={A few remarks}]
+
+Surprisingly, the amount of code needed for insert migration is not that large.
+This makes one wonder why \TEX\ does not provide this feature itself as it could
+have saved macro writers quite some time and headaches. Performance can be a
+reason, unpredictable usage and side effects might be another. Only one person
+knows the answer.
+
+In \CONTEXT\ this mechanism is built in and it can be enabled by saying:
+
+\starttyping
+\automigrateinserts
+\automigratemarks
+\stoptyping
+
+As you can see here, we can also migrate marks. Future versions of \CONTEXT\ will
+do this automatically and also provide some control over what classes of inserts
+are moved around. We will probably overhaul the note handling mechanism a few
+more times anyway as \LUATEX\ evolves and the demands from critical editions that
+use many kind of notes raise.

+                current = last

+\startchapter[title={Introduction}]
+
+We're halfway the development of \LUATEX\ (mid 2009) and substantial parts of
+\CONTEXT\ have been rewritten using a mixture of \LUA\ and \TEX. In another
+document, \quotation {\CONTEXT\ \MKII--\MKIV, the history of \LUATEX\
+2006--2009}, we have kept track of how both systems evolved so far\footnote
+{Parts of this have been published in usergroup magazines like the \MAPS,
+\TUGBOAT, and conference proceedings of \EUROTEX\ and \TUG.}. Here we continue
+that story which eventually will end with both systems being stable and more of
+less complete in their basic features.
+
+The title of this document needs some explanation, although the symbols on the
+cover might give a clue already. In \CONTEXT\ \MKIV, as it is now, we mix several
+languages:
+
+\startitemize[packed]
+\startitem
+    good old \TEX: here you will see \type {{}} all over the place
+\stopitem
+\startitem
+    fancy \METAPOST: there we use quite some \type {()}
+\stopitem
+\startitem
+    lean and mean \LUA: both \type{{}} and \type {()} show up a lot there
+\stopitem
+\startitem
+    unreadable but handy \XML: immediately recognizable by the use of \type {<>}
+\stopitem
+\stopitemize
+
+As we use all of them mixed, you can consider \MKIV\ to be a hybrid system and
+just as with hybrid cars, efficiency is part of the concept.

+In this graphic we've given \LUA\ a somewhat different place than the other three
+languages. First of all we have \LUA\ inside \TEX, which is kind of hidden, but
+at the same time we can use \LUA\ to provide whatever extra features we need,
+especially when we've reached the state where we can load libraries. In a similar
+fashion we have utilities (now all written in \LUA) that can manage your workflow
+or aspects of a run (the \type {mtxrun} script plays a central role in this).
+
+The mentioned history document was (and still is) a rather good testcase for
+\LUATEX\ and \MKIV. We explore some new features and load a lot of fonts, some
+really large. This document will also serve that purpose. This is one of the
+reasons why we have turned on grid snapping (and occasionally some tracing).
+
+Keeping track of the history of \LUATEX\ and \MKIV\ in a document serves several
+purposes. Of course it shows what has been done. It also serves as a reminder of
+why it was done that way. As mentioned it serves as test, both in functionality
+and performance, and as such it's always one of the first documents we run after
+a change in the code. Most of all this document serves as an extension to my
+limited memory. When I look at my source code I often can remember when and why
+it was done that way at that time. However, writing it down more explicitly helps
+me to remember more and might help users to get some insight in the developments
+and decisions made. \footnote {I read a lot and regret that I forget most of what
+I read so fast. I might as well forget what I wrote so have some patience with me
+as I repeat myself occasionally.}
+
+A couple of new features were added to \LUATEX\ in 2010 but the years 2011 and
+2012 were mostly spent on fixing issues and reaching a stable state. In parallel
+parts of \CONTEXT\ were rewritten using \LUA\ and new possibilities have been
+explored. Indeed \LUATEX\ had become pretty stable, especially because we used it
+in production. There are still a lot of things on the agenda but with \LUATEX\
+0.75 we have reached yet another milestone: integration of \LUA\ 5.2, exploration
+of \LUAJIT, and the move forward to a version of \METAPOST\ that supports doubles
+as numeric type. Luigi Scarso and I also started the SwigLib project that will
+make the use of external libraries more easy.
+
+Of course, although I wrote most of the text, this document is as much a
+reflection of what Taco Hoekwater and Hartmut Henkel come up with, but all errors
+you find here are definitely mine. Some chapters have been published in \TUGBOAT,
+the \MAPS\ and other usergroup journals. Some chapters have become manuals, like
+the one on spreadsheets. I also owe thanks to the \CONTEXT\ community and those
+active on the mailing list: it's a real pleasure to see how fast new features are
+picked up and how willing to test users are when new betas show up.

+\startchapter[title={Italic correction}]
+
+\component hybrid-note
+
+\startsection [title={Introduction}]
+
+During the 2011 \CONTEXT\ conference there were presentations by Thomas Schmitz
+and Jano Kula where they demonstrated advanced rendering of document source
+encoded in \XML. When looking at the examples on screen using many fonts I
+realized that (also given my own workflows) it was about time to look into
+automated italic correction in the perspective of \MKIV.
+
+In the Lucida Math project it already became clear that italics in \OPENTYPE\
+math fonts are to be ignored. And, as in regular \OPENTYPE\ fonts italic
+correction is basically non|-|existent some alternative approach is needed there
+as well. In \CONTEXT\ you can already for quite a while enable the \type {itlc}
+feature which adds italic correction to shapes using some heuristics. However, in
+\TEX\ this kind of correction is never applied automatically but is triggered by
+the \type {\/} command. Commands like \type {\em} deal with italic correction
+automatically but otherwise you need to take care of it yourself. In a time when
+you not always have control over the source code or when you are coding in a
+format that has no provisions for it (for instance \XML) some further automatism
+makes sense. You might even wonder if explicit corrections still make sense.
+
+In this chapter we discuss an alternative approach in \MKIV. This is a typical
+example of an experimental feature that might need further discussion (probably
+at a next conference). One of our mottos is that the document source should be as
+clean as possible and this is one way to go.
+
+\stopsection
+
+\startsection [title={Some preparations}]
+
+Adding italic correction to a font is easy: you just add the right feature
+directive. You can do this for all italic (or oblique) fonts in one go:
+
+\starttyping
+\definefontfeature[default][default][itlc=yes]
+\stoptyping
+
+At some point this might become the default in \CONTEXT. After that the \type
+{\/} command can do the job, but as mentioned, we don't really want to do this
+each time it's needed. If you never plan to use that command you can disable
+\TEX's built|-|in mechanism completely by setting the \type {textitalics}
+parameter.
+
+\starttyping
+\definefontfeature[default][default][itlc=yes,textitalics=yes]
+\stoptyping
+
+It even makes sense then to redefine the the \type {\/} command:
+
+\starttyping
+\let\/=/
+\stoptyping
+
+so that we have a nice escape in tune with the other escapes.
+
+\stopsection
+
+\startsection [title={Controlling correction}]
+
+In the following examples we will use Cambria as an example as it shows the
+effect rather prominently.
+
+\startbuffer[setups]
+\definefontfeature[itclyes][default][itlc=yes,textitalics=no]
+
+\definefont[itlcregular]   [name:cambria*itclyes sa 4]
+\definefont[itlcbold]      [name:cambriabold*itclyes sa 4]
+\definefont[itlcitalic]    [name:cambriaitalic*itclyes sa 4]
+\definefont[itlcbolditalic][name:cambriabolditalic*itclyes sa 4]
+\stopbuffer

+

+
+\defineframed[ITLCexampleA][frame=off,foregroundcolor=white,background=color,backgroundcolor=red]
+\defineframed[ITLCexampleB][frame=off,foregroundcolor=white,background=color,backgroundcolor=blue]
+\defineframed[ITLCexampleC][frame=off,foregroundcolor=white,background=color,backgroundcolor=green]
+\defineframed[ITLCexampleD][frame=off,foregroundcolor=white,background=color,backgroundcolor=yellow]
+\defineframed[ITLCexampleE][frame=off,foregroundcolor=white,background=color,backgroundcolor=gray]
+
+We start with a simple case: just an emphasized word in a small
+line:
+
+\starttyping
+\setupitaliccorrection[none]\tf test {\it test} test
+\setupitaliccorrection[none]\tf test {\it test\/} test}
+\setupitaliccorrection[text]\tf test {\it test} test}
+\stoptyping
+
+Decorated for the purpose of this demonstration this comes out as follows:
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip
+    \ITLCexampleA{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test} test}   \par
+    \ITLCexampleB{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test\/} test} \par
+    \ITLCexampleC{\setupitaliccorrection[text]\itlcregular test {\itlcitalic test} test}   \par
+\egroup \stoplinecorrection
+
+In the first line no correction is applied. The second line shows \TEX\ in action
+and the third line demonstrates the automatically applied correction. The
+explicit directive in the second lines of course gives most control but is also a
+no|-|go when you have lots of them.
+
+Actually, \TEX\ is clever enough to ignore multiple corrections: it will only
+apply one after a glyph.
+
+\starttyping
+\setupitaliccorrection[none]\tf test {\it test} test}
+\setupitaliccorrection[none]\tf test {\it test\/} test}
+\setupitaliccorrection[none]\tf test {\it test\/\/\/\/} test}
+\stoptyping
+
+So we get this:
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip
+    \ITLCexampleA{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test} test} \par
+    \ITLCexampleB{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test\/} test} \par
+    \ITLCexampleC{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test\/\/\/\/} test} \par
+\egroup \stoplinecorrection
+
+It can be argued that in a decent usage of \CONTEXT\ you will never switch to
+another font this way. Instead you will do this:
+
+\starttyping
+\definehighlight[important][style=\it]
+
+test \important{test} test
+\stoptyping
+
+However, this will not correct at all, so in fact you have to use an environment
+that takes care of automatically adding the \type {\/} at the end. Quite from the
+start the \type {\em} command does this, with the added benefit of dealing with
+bold and nested emphasizing.
+
+Which brings us to cases where you don't want to apply correction, like:
+
+\starttyping
+\setupitaliccorrection[none]\tf test {\it test}{\bi test}
+\setupitaliccorrection[none]\tf test {\it test\/}{\bi test}
+\setupitaliccorrection[text]\tf test {\it test}{\bi test}
+\stoptyping
+
+Now we get:
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip
+    \ITLCexampleA{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test}{\itlcbolditalic test}}   \par
+    \ITLCexampleB{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test\/}{\itlcbolditalic test}} \par
+    \ITLCexampleC{\setupitaliccorrection[text]\itlcregular test {\itlcitalic test}{\itlcbolditalic test}}   \par
+\egroup \stoplinecorrection
+
+A variant on this is:
+
+\starttyping
+\setupitaliccorrection[none]\tf test {\it test   \bi test}
+\setupitaliccorrection[none]\tf test {\it test\/ \bi test}
+\setupitaliccorrection[text]\tf test {\it test   \bi test}
+\stoptyping
+
+which gives:
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip
+    \ITLCexampleA{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test   \itlcbolditalic test}} \par
+    \ITLCexampleB{\setupitaliccorrection[none]\itlcregular test {\itlcitalic test\/ \itlcbolditalic test}} \par
+    \ITLCexampleC{\setupitaliccorrection[text]\itlcregular test {\itlcitalic test   \itlcbolditalic test}} \par
+\egroup \stoplinecorrection
+
+So, no italic correction is added between italic shapes of different fonts.
+Ideally we should have some inter|-|character kerning, but that is currently
+beyond this mechanism.
+
+What does the \type {text} mean in the setup command? The following table tells
+what keywords can be passed:
+
+\starttabulate
+\NC \type {text}   \NC only apply correction to running text \NC \NR
+\NC \type {always} \NC also apply correction to end end of a list \NC \NR
+\NC \type {global} \NC enable this mechanism globally (more efficient) \NC \NR
+\NC \type {none}   \NC disable this mechanism \NC \NR
+\stoptabulate
+
+The difference between \type {text} and \type {always} is best demonstrated with
+an example:
+
+\starttyping
+\setupitaliccorrection[none]\tf   test {\it test}}
+\setupitaliccorrection[always]\tf test {\it test}}
+\setupitaliccorrection[text]\tf   test {\it test}}
+\stoptyping
+
+This gives:
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip
+    \ITLCexampleA{\setupitaliccorrection[none]\itlcregular   test {\itlcitalic test}} \par
+    \ITLCexampleD{\setupitaliccorrection[always]\itlcregular test {\itlcitalic test}} \par
+    \ITLCexampleC{\setupitaliccorrection[text]\itlcregular   test {\itlcitalic test}} \par
+\egroup \stoplinecorrection
+
+The \type {always} option will flush pending corrections at a boundary, like the
+edge of a box (or line). Contrary to \TEX's italic corrections, the \MKIV\
+variants are glue and they will disappear whenever \TEX\ likes to get rid of
+glue, for instance at line breaks. \footnote {There is some room for improvement
+here, for instance we can take penalties into account.}
+
+While writing this, we're still talking of an experimental setup so there might
+be extensions or changes to this mechanism. \footnote {For instance, I'm
+considering extending this mechanism to provide kerning between fonts, something
+for a rainy afternoon.}
+
+As it's just a guess you can influence the amount of automatic correction by
+specifying a factor. We show an exmaple of this.

+
+You can keep track of what gets done by enabling a tracker:
+
+\starttyping
+\enabletrackers[typesetters.italics]
+\stoptyping
+
+You will notice that there are occasional reports about correction being
+inserted, ignored and removed. As node lists are parsed there is some extra
+overhead, but not that much. The \TEX\ solution (using \type {\/}) is quit
+efficient because that command directly injects a kern without too much analysis.
+You can gain some efficiency for the automated variant by using the \type
+{global} option:
+
+\starttyping
+\setupitaliccorrection[always,global]
+\stoptyping
+
+Also, you can disable \TEX's mechanism effectively by not passing the italic
+information to the font machinery at all:
+
+\starttyping
+\definefontfeature[italics][default][itlc=yes,textitalics=yes]
+\stoptyping
+
+The \type {itlc} feature will tag the font for italic corrections but the \type
+{textitalics} option will make sure that this information is not passed to the
+\TEX\ font handler but kept private.
+
+As adding the italic corrections to a font takes memory and a little bit of extra
+load time, we can delay this process till it is really needed.
+
+\starttyping
+\definefontfeature[italics][default][itlc=yes,textitalics=delay]
+\stoptyping
+
+In this case the correction will be calculated when needed and cached for later
+usage. At some point this might become the default \CONTEXT\ behaviour.
+
+\stopsection
+
+\startsection [title={Math}]
+
+Italic correction in math plays a role when dealing with traditional \TEX\ fonts,
+where glyph dimensions can have a special meaning. However, in \OPENTYPE\ math
+the correction is mostly ignored. You can disable it altogether and let an
+alternative mechanism deal with it. This mechanism is still somewhat experimental
+but is controlled as follows:
+
+\starttyping
+\switchtobodyfont[xits]
+\setupmathematics[italics=no] test $a;b;a; b; f;$ test}
+\setupmathematics[italics=1]  test $a;b;a; b; f;$ test}
+\setupmathematics[italics=2]  test $a;b;a; b; f;$ test}
+\setupmathematics[italics=3]  test $a;b;a; b; f;$ test}
+\setupmathematics[italics=4]  test $a;b;a; b; f;$ test}
+\stoptyping
+
+This gives:
+
+\start \switchtobodyfont[xits,42pt] \stop
+
+\startlinecorrection[blank] \vbox \bgroup \offinterlineskip \enabletrackers[math.italics]
+    \ITLCexampleE{\switchtobodyfont[xits,42pt]\setupmathematics[italics=no] test $a;b;a; b; f;$ test}\par

+\egroup \stoplinecorrection \disabletrackers[math.italics]
+
+The actual rendering can depend on the settings in the goodies file, for

+
+\starttyping

+    disableengine = true, % feature: mathitalics=yes

+\startsection [title={Introduction}]
+
+Reading occasional announcements about \LUAJIT,\footnote {\LUAJIT\ is written by
+Mike Pall and more information about it and the technology it uses is at \type
+{http://luajit.org}, a site also worth visiting for its clean design.} one starts
+wondering if just||in||time compilation can speed up \LUATEX. As a side track of
+the \SWIGLIB\ project and after some discussion, Luigi Scarso decided to compile
+a version of \LUATEX\ that had the \JIT\ compiler as the \LUA\ engine. That's
+when our journey into \JIT\ began.
+
+We started with \LINUX\ 32-bit as this is what Luigi used at that time. Some
+quick first tests indicated that the \LUAJIT\ compiler made \CONTEXT\ \MKIV\ run
+faster but not that much. Because \LUAJIT\ claims to be much faster than stock
+\LUA, Luigi then played a bit with \type {ffi}, i.e.\ mixing \CCODE\ and \LUA,
+especially data structures. There is indeed quite some speed to gain here;
+unfortunately, we would have to mess up the \CONTEXT\ code base so much that one
+might wonder why \LUA\ was used in the first place. I could confirm these
+observations in a Xubuntu virtual machine in \VMWARE\ running under 32-bit
+Windows 8. So, we decided to conduct some more experiments.
+
+A next step was to create a 64-bit binary because the servers at \PRAGMA\ are
+\KVM\ virtual machines running a 64-bit OpenSuse 12.1 and 12.2. It took a bit of
+effort to get a \JIT\ version compiled because Luigi didn't want to mess up the
+regular codebase too much. This time we observed a speedup of about 40\% on some
+runs so we decided to move on to \WINDOWS\ to see if we could observe a similar
+effect there. And indeed, when we adapted Akira Kakuto's \WINDOWS\ setup a bit we
+could compile a version for \WINDOWS\ using the native \MICROSOFT\ compiler. On
+my laptop a similar speedup was observed, although by then we saw that in
+practice a 25\% speedup was about what we could expect. A bonus is that making
+formats and identifying fonts is also faster.
+
+So, in that stage, we could safely conclude that \LUATEX\ combined with \LUAJIT\
+made sense if you want a somewhat faster version. But where does the speedup come
+from? The easiest way to see if jitting has effect is to turn it on and off.
+
+\starttyping
+jit.on()
+jit.off()
+\stoptyping
+
+To our surprise \CONTEXT\ runs are not much influenced by turning the jitter on
+or off. \footnote {We also tweaked some of the fine|-|tuning parameters of
+\LUAJIT\ but didn't notice any differences. In due time more tests will
+be done.} This means that the improvement comes from other places:
+
+\startitemize[packed,n]
+\startitem The virtual machine is a different one, and targets the platforms that
+it runs on. This means that regular bytecode also runs faster. \stopitem
+\startitem The garbage collector is the one from \LUA\ 5.2, so that can make a
+difference. It looks like memory consumption is somewhat lower. \stopitem
+\startitem Some standard library functions are recognized and supported in a more
+efficient way. Think of \type {math.sin}. \stopitem
+\startitem Some built-in functions like \type {type} are probably dealt with in
+a more efficient way. \stopitem
+\stopitemize
+
+The third item is an important one. We don't use that many standard functions.
+For instance, if we need to go from characters to bytes and vice versa, we have
+to do that for \UTF\ so we use some dedicated functions or \LPEG. If in \CONTEXT\
+we parse strings, we often use \LPEG\ instead of string functions anyway. And if
+we still do use string functions, for instance when dealing with simple strings,
+it only happens a few times.
+
+The more demanding \CONTEXT\ code deals with node lists, which means frequent
+calls to core \LUATEX\ functions. Alas, jitting doesn't help much there unless we
+start messing with \type {ffi} which is not on the agenda. \footnote {If we want
+to improve these mechanisms it makes much more sense to make more helpers.
+However, profiling has shown us that the most demanding code is already quite
+optimized.}
+
+\stopsection
+
+\startsection[title=Benchmarks]
+
+Let's look at some of the benchmarks. The first one uses \METAPOST\ and because
+we want to see if calculations are faster, we draw a path with a special pen so
+that some transformations have to be done in the code that generates the \PDF\
+output. We only show the \MSWINDOWS\ and 64-bit \LINUX\ tests here. The 32-bit
+tests are consistent with those on \MSWINDOWS\ so we didn't add those timings
+here (also because in the meantime Luigi's machine broke down and he moved on
+to 64 bits).
+
+\typefile{benchmark-1.tex}
+
+The following times are measured in seconds. They are averages of 5~runs. There
+is a significant speedup but jitting doesn't do much.

+Our second example uses multiple fonts in a paragraph and adds color as well.
+Although well optimized, font||related code involves node list parsing and a
+bit of calculation. Color again deals with node lists and the backend
+code involves calculations but not that many. The traditional run on \LINUX\ is
+somewhat odd, but might have to do with the fact that the \METAPOST\ library
+suffers from the 64 bits. It is at least an indication that optimizations make
+less sense if there is a different dominant weak spot. We have to look into this
+some time.
+
+\typefile{benchmark-2.tex}
+
+Again jitting has no real benefits here, but the overall gain in speed is quite

+This benchmark writes quite a lot of data to the console, which can have impact on

+There is a lot of file reading going on here, but normally the operating system

+The third benchmark is one that we often use for testing regression in speed of

+\startsection[title=Conclusions]
+
+So, does it make sense to complicate the \LUATEX\ build with \LUAJIT ? It does
+when speed matters, for instance when \CONTEXT\ is run as a service. Some 25\% gain
+in speed means less waiting time, better use of \CPU\ cycles, less energy
+consumption, etc. On the other hand, computers are still becoming faster and compared
+to those speed|-|ups the 25\% is not that much. Also, as \TEX\ deals with files,
+the advance of \SSD\ disks and larger and faster memory helps too. Faster and
+larger \CPU\ caches contributes too. On the other hand, multiple cores don't help that
+much on a system that only runs \TEX. Interesting is that multi|-|core
+architectures tend to run at slower speeds than single cores where more heat can
+be dissipated and in that respect servers mostly running \TEX\ are better off with
+fewer cores that can run at higher frequencies. But anyhow, 25\% is still better
+than nothing and it makes my old laptop feel faster. It prolongs the lifetime
+of machines!
+
+Now, say that we cannot speed up \TEX\ itself that much, but that there is still
+something to gain at the \LUA\ end \emdash\ what can we reasonably expect? First of all
+we need to take into account that only part of the runtime is due to \LUA. Say
+that this is 25\% for a document of average complexity.
+
+\startnarrower
+runtime\low{tex} + runtime\low{lua} = 100
+\stopnarrower
+
+We can consider the time needed by \TEX\ to be constant; so if that is
+75\% of the total time (say 100 seconds) to begin with, we have:
+
+\startnarrower
+75 + runtime\low{lua} = 100
+\stopnarrower
+
+It will be clear that if we bring down the runtime to 80\% (80 seconds) of the
+original we end up with:
+
+\startnarrower
+75 + runtime\low{lua} = 80
+\stopnarrower
+
+And the 25 seconds spent in \LUA\ went down to 5, meaning that \LUA\ processing
+got 5 times faster! It is also clear that getting much more out of \LUA\
+becomes hard. Of course we can squeeze more out of it, but \TEX\ still needs its
+time. It is hard to measure how much time is actually spent in \LUA. We do keep
+track of some times but it is not that accurate. These experiments and the gain
+in speed indicate that we probably spend more time in \LUA\ than we first
+guessed. If you look in the \CONTEXT\ source it's not that hard to imagine that
+indeed we might well spend 50\% or more of our time in \LUA\ and|/|or in
+transferring control between \TEX\ and \LUA. So, in the end there still might
+be something to gain.
+
+Let's take benchmark 4 as an example. At some point we measured for a regular
+\LUATEX\ 0.74 run 27.0 seconds and for a \LUAJITTEX\ run 23.3 seconds. If we
+assume that the \LUAJIT\ virtual machine is twice as fast as the normal one, some
+juggling with numbers makes us conclude that \TEX\ takes some 19.6 seconds of
+this. An interesting border case is \type {\directlua}: we sometimes pass quite
+a lot of data and that gets tokenized first (a \TEX\ activity) and the resulting
+token list is converted into a string (also a \TEX\ activity) and then converted
+to bytecode (a \LUA\ task) and when okay executed by \LUA. The time involved in
+conversion to byte code is probably the same for stock \LUA\ and \LUAJIT.
+
+In the \LUATEX\ case, 30\% of the runtime for benchmark 4 is on \LUA's tab, and
+in \LUAJITTEX\ it's 15\%. We can try to bring down the \LUA\ part even more, but
+it makes more sense to gain something at the \TEX\ end. There macro expansion
+can be improved (read: \CONTEXT\ core code) but that is already rather
+optimized.
+
+Just for the sake of completeness Luigi compiled a stock \LUATEX\ binary for 64-bit
+\LINUX\ with the \type {-o3} option (which forces more inlining of functions
+as well as a different switch mechanism). We did a few tests and this is the result:
+
+\starttabulate[|lTB|r|r|]
+\HL
+\NC              \NC \LUATEX\ 0.74 -o2 \NC \LUATEX\ 0.74 - o3 \NC \NR

+\NC benchmark-1  \NC 15.5              \NC 15.0               \NC \NR

+\HL
+\stoptabulate
+
+This time we used \type {--batch} and \type {--silent} to eliminate terminal
+output. So, if you really want to squeeze out the maximum performance you need
+to compile with \type {-o3}, use \LUAJITTEX\ (with the faster virtual machine)
+but disable \JIT\ (disabled by default anyway).
+

+%   tex         = 19.6
+%
+% ratios:
+%
+% tex : lua = 70 : 30
+% tex : jit = 85 : 15
+
+We have no reason to abandon stock \LUA. Also, because during these experiments
+we were still using \LUA\ 5.1 we started wondering what the move to 5.2 would
+bring. Such a move forward also means that \CONTEXT\ \MKIV\ will not depend on
+specific \LUAJIT\ features, although it is aware of it (this is needed because we
+store bytecodes). But we will definitely explore the possibilities and see where
+we can benefit. In that respect there will be a way to enable and
+disable jitting. So, users have the choice to use either stock \LUATEX\ or the
+\JIT||aware version but we default to the regular binary.
+
+As we use stock \LUA\ as benchmark, we will use the \type {bit32} library, while
+\LUAJIT\ has its own bit library. Some functions can be aliased so that is no big
+deal. In \CONTEXT\ we use wrappers anyway. More problematic is that we want to
+move on to \LUA\ 5.2 and not all 5.2 features are supported (yet) in \LUAJIT. So,
+if \LUAJIT\ is mandatory in a workflow, then users had better make sure that the
+\LUA\ code is compatible. We don't expect too many problems in \CONTEXT\ \MKIV.
+
+\stopsection
+
+\startsection[title=About speed]
+
+It is worth mentioning that the \LUA\ version in \LUATEX\ has a patch for
+converting floats into strings. Instead of some \type {INF#} result we just
+return zero, simply because \TEX\ is integer||based and intercepting incredibly
+small numbers is too cumbersome. We had to apply the same patch in the \JIT\
+version.
+
+The benchmarks only indicate a trend. In a real document much more happens than
+in the above tests. So what are measurements worth? Say that we compile the \TEX
+book. This grandparent of all documents coded in \TEX\ is rather plainly coded
+(using of course plain \TEX) and compiles pretty fast. Processing does not suffer
+from complex expansions, there is no color, hardly any text manipulation, it's
+all 8 bit, the pagebuilder is straightforward as is all spacing. Although on my
+old machine I can get \CONTEXT\ to run at over 200 pages per second, this quickly
+drops to 10\% of that speed when we add some color, backgrounds, headers and
+footers, font switches, etc.
+
+So, running documents like the \TEX book for comparing the speed of, say,
+\PDFTEX, \XETEX, \LUATEX\ and now \LUAJITTEX\ makes no sense. The first one is
+still eight bit, the rest are \UNICODE. Also, the \TEX book uses traditional
+fonts with traditional features so effectively that it doesn't rely on anything
+that the new engines provide, not even \ETEX\ extensions. On the other hand, a
+recent document uses advanced fonts, properties like color and|/|or
+transparencies, hyperlinks, backgrounds, complex cover pages or chapter openings,
+embeds graphics, etc. Such a document might not even process in \PDFTEX\ or
+\XETEX, and if it does, it's still comparing different technologies: eight bit
+input and fast fonts in \PDFTEX, frozen \UNICODE\ and wide font support in
+\XETEX, instead of additional trickery and control, written in \LUA. So, when we
+investigate speed, we need to take into account what (font and input)
+technologies are used as well as what complicating layout and rendering features
+play a role. In practice speed only matters in an edit|-|view cycle and services
+where users wait for some result.
+
+It's rather hard to find a recent document that can be used to compare these
+engines. The best we could come up with was the rendering of the user interface
+documentation.

+Keep in mind that \type{texexec} is a \RUBY\ script and uses \type {kpsewhich}
+while \type {context} uses \LUA\ and its own (\TDS||compatible) file manager. But
+still, it is interesting to see that there is not that much difference if we keep
+\JIT\ out of the picture. This is because in \MKIV\ we have somewhat more clever
+\XML\ processing, although earlier measurements have demonstrated that in this
+case not that much speedup can be assigned to that.
+
+And so recent versions of \MKIV\ already keep up rather well with the older eight
+bit world. We do way more in \MKIV\ and the interfacing macros are nicer but
+potentially somewhat slower. Some mechanisms might be more efficient because of
+using \LUA, but some actually have more overhead because we keep track of more
+data. Font feature processing is done in \LUA, but somehow can keep up with the
+libraries used in \XETEX, or at least is not that significant a difference,
+although I can think of more demanding tasks. Of course in \LUATEX\ we can go
+beyond what libraries provide.
+
+No matter what one takes into account, performance is not that much worse in
+\LUATEX, and if we enable \JIT\ and so remove some of the traditional \LUA\
+virtual machine overhead, we're even better off. Of course we need to add a
+disclaimer here: don't force us to prove that the relative speed ratios are the
+same for all cases. In fact, it being so hard to measure and compare, performance
+can be considered to be something taken for granted as there is not that much we
+can do about getting nicer numbers, apart from maybe parallelizing which brings
+other complexities into the picture. On our servers, a few other virtual machines
+running \TEX\ services kicking in at the same time, using \CPU\ cycles, network
+bandwidth (as all data lives someplace else) and asking for disk access have much
+more impact than the 25\% we gain. Of course if all processes run faster then
+we've gained something.
+
+For what it's worth: processing this text takes some 2.3 seconds on my laptop for
+regular \LUATEX\ and 1.8 seconds with \LUAJITTEX, including the extra overhead of
+restarting. As this is a rather average example it fits earlier measurements.
+
+Processing a font manual (work in progress) takes \LUAJITTEX\ 15 seconds for 112
+pages compared to 18.4 seconds for \LUATEX. The not yet finished manual loads 20
+different fonts (each with multiple instances), uses colors, has some \METAPOST\
+graphics and does some font juggling. The gain in speed sounds familiar.
+
+\stopsection
+
+\startsection[title=The future]
+
+At the 2012 \LUA\ conference Roberto Ierusalimschy mentioned that the virtual
+machine of \LUAJIT\ is about twice as fast due to it being partly done in
+assembler while the regular machinery is written in standard \CCODE\ and keeps
+portability in mind.
+
+He also presented some plans for future versions of \LUA. There will be some
+lightweight helpers for \UTF. Our experiences so far are that only a handful of
+functions are actually needed: byte to character conversions and vice versa,
+iterators for \UTF\ characters and \UTF\ values and maybe a simple substring
+function is probably enough. Currently \LUATEX\ has some extra string iterators
+and it will provide the converters as well.
+
+There is a good chance that \LPEG\ will become a standard library (which it
+already is in \LUATEX), which is also nice. It's interesting that, especially on
+longer sequences, \LPEG\ can beat the string matchers and replacers, although
+when in a substitution no match and therefore no replacements happen, the regular
+gsub wins. We're talking small numbers here, in daily usage \LPEG\ is about as
+efficient as you can wish. In \CONTEXT\ we have a \type {lpeg.UR} and \type
+{lpeg.US} and it would be nice to have these as native \UTF\ related methods, but
+I must admit that I seldom need them.
+
+This and other extensions coming to the language also have some impact on a \JIT\
+version: the current \LUAJIT\ is already not entirely compatible with \LUA\ 5.2
+so you need to keep that into account if you want to use this version of \LUATEX.
+So, unless \LUAJIT\ follows the mainstream development, as \CONTEXT\ \MKIV\ user
+you should not depend on it. But at the moment it's nice to have this choice.
+
+The yet experimental code will end up in the main \LUATEX\ repository in time
+before the \TEX\ Live 2013 code freeze. In order to make it easier to run both
+versions alongside, we have added the \LUA\ 5.2 built|-|in library \type {bit32}
+to \LUAJITTEX. We found out that it's too much trouble to add that library to
+\LUA~5.1 but \LUATEX\ has moved on to 5.2 anyway.
+
+\stopsection
+
+\startsection[title=Running]
+
+So, as we will definitely stick to stock \LUA, one might wonder if it makes sense
+to officially support jitting in \CONTEXT. First of all, \LUATEX\ is not
+influenced that much by the low level changes in the \API\ between 5.1 and 5.2.
+Also \LUAJIT\ does support the most important new 5.2 features, so at the moment
+we're mostly okay. We expect that eventually \LUAJIT\ will catch up but if not,
+we are not in big trouble: the performance of stock \LUA\ is quite okay and above
+all, it's portable! \footnote {Stability and portability are important properties
+of \TEX\ engines, which is yet another reason for using \LUA. For those doing
+number crunching in a document, \JIT\ can come in handy.} For the moment you can
+consider \LUAJITTEX\ to be an experiment and research tool, but we will do our
+best to keep it production ready.
+
+So how do we choose between the two engines? After some experimenting with
+alternative startup scenarios and dedicated caches, the following solution was
+reached:
+
+\starttyping
+context --engine=luajittex ...
+\stoptyping
+
+The usual preamble line also works:
+
+\starttyping
+% engine=luajittex
+\stoptyping
+
+As the main infrastructure uses the \type {luatex} and related binaries, this
+will result in a relaunch: the \type {context} script will be restarted using
+\type {luajittex}. This is a simple solution and the overhead is rather minimal,
+especially compared to the somewhat faster run. Alternatively you can copy \type
+{luajittex} over \type {luatex} but that is more drastic. Keep in mind that \type
+{luatex} is the benchmark for development of \CONTEXT, so the \JIT\ aware version
+might fall behind sometimes.
+
+Yet another approach is adapting the configuration file, or better, provide (or
+adapt) your own \type {texmfcnf.lua} in for instance \type {texmf-local/web2c}
+path:
+
+\starttyping
+return {
+  type    = "configuration",
+  version = "1.2.3",
+  date    = "2012-12-12",
+  time    = "12:12:12",
+  comment = "Local overloads",
+  author  = "Hans Hagen, PRAGMA-ADE, Hasselt NL",
+  content = {
+    directives = {
+      ["system.engine"] = "luajittex",
+    },
+  },
+}
+\stoptyping
+
+This has the same effect as always providing \type {--engine=luajittex} but only
+makes sense in well controlled situations as you might easily forget that it's
+the default. Of course one could have that file and just comment out the
+directive unless in test mode.
+
+Because the bytecode of \LUAJIT\ differs from the one used by \LUA\ itself we
+have a dedicated format as well as dedicated bytecode compiled resources (for
+instance \type {tmb} instead of \type {tmc}). For most users this is not
+something they should bother about as it happens automatically.
+
+Based on experiments, by default we have disabled \JIT\, so we only benefit from
+the faster virtual machine. Future versions of \CONTEXT\ might provide some
+control over that but first we want to conduct more experiments.
+
+\stopsection
+
+\startsection[title=Addendum]
+
+These developments and experiments took place in November and December 2012. At
+the time of this writing we also made the move to \LUA\ 5.2 in stock \LUATEX; the
+first version to provide this was 0.74. Here are some measurements on Taco
+Hoekwater's 64-bit \LINUX\ machine:

+
+There is a good chance that this is due to improvements of the garbage collector,
+virtual machine and string handling. It also looks like memory consumption is a
+bit less. Some speed optimizations in reading files have been removed (at least
+for now) and some patches to the \type {format} function (in the \type {string}
+namespace) that dealt with (for \TEX) unfortunate number conversions have not
+been ported. The code base is somewhat cleaner and we expect to be able to split
+up the binary in a core program plus some libraries that are loaded on demand.
+\footnote {Of course this poses some constraints on stability as components get
+decoupled, but this is one of the issues that we hope to deal with properly in
+the library project.} In general, we don't expect too many issues in the
+transition to \LUA\ 5.2, and \CONTEXT\ is already adapted to support \LUATEX\
+with 5.2 as well as \LUAJITTEX\ with an older version.
+
+Running the same tests on a 32-bit \MSWINDOWS\ machine gives this:

+The gain is less impressive but the machine is rather old and we can benefit less
+from modern \CPU\ properties (cache, memory bandwidth, etc.). I tend to conclude
+that there is no significant improvement here but it also doesn't get worse.
+However we need to keep in mind that file \IO\ is less optimal in 0.74 so this
+might play a role. As usual, runtime is negatively influenced by the relatively
+slow speed of displaying messages on the console (even when we use \type
+{console2}).
+
+A few days before the end of 2012, Akira Kakuto compiled native \MSWINDOWS\
+binaries for both engines. This time I decided to run a comparison inside the
+\SCITE\ editor, that has very fast console output. \footnote {Most of my personal
+\TEX\ runs are from within \SCITE, while most runs on the servers are in batch
+mode, so normally the overhead of the console is acceptable or even neglectable.}

+
+In this text, the term \JIT\ has come up a lot but you might rightfully wonder if
+the observations here relate to \JIT\ at all. For the moment I tend to conclude
+that the implementation of the virtual machine and garbage collection have more
+impact than the actual just||in||time compilation. More exploration of \JIT\ is
+needed to see if we can really benefit from that. Of course the fact that we use
+a bit less memory is also nice. In case you wonder why I bother about speed at
+all: we happen to run \LUATEX\ mostly as a (remote) service and generating a
+bunch of (related) documents takes a bit of time. Bringing the waiting down from
+15 to 10 seconds might not sound impressive but it makes a difference when it is
+someone's job to generate these sets.
+
+In summary: just before we entered 2013, we saw two rather fundamental updates of
+\LUATEX\ show up: an improved traditional one with \LUA\ 5.2 as well as the
+somewhat faster \LUAJITTEX\ with a mixture between 5.1 and 5.2. And in 2013 we
+will of course try to make them both even more attractive.

+\startchapter[title={The language mix}]
+
+During the third \CONTEXT\ conference that ran in parallel to Euro\TEX\ 2009 in
+The Hague we had several sessions where \MKIV\ was discussed and a few upcoming
+features were demonstrated. The next sections summarize some of that. It's hard
+to predict the future, especially because new possibilities show up once \LUATEX\
+is opened up more, so remarks about the future are not definitive.
+
+\startsection[title={\TEX}]
+
+From now on, if I refer to \TEX\ in the perspective of \LUATEX\ I mean \quotation
+{Good Old \TEX}, the language as well as the functionality. Although \LUATEX\
+provides a couple of extensions it remains pretty close to compatible to its
+ancestor, certainly from the perspective of the end user.
+
+As most \CONTEXT\ users code their documents in the \TEX\ language, this will
+remain the focus of \MKIV. After all, there is no real reason to abandon it.
+However, although \CONTEXT\ already stimulates users to use structure where
+possible and not to use low level \TEX\ commands in the document source, we will
+add a few more structural variants. For instance, we already introduced \type
+{\startchapter} and \type {\startitem} in addition to \type {\chapter} and \type
+{\item}.
+
+We even go further, by using key|/|value pairs for defining section titles,
+bookmarks, running headers, references, bookmarks and list entries at the start
+of a chapter. And, as we carry around much more information in the (for \TEX\ so
+typical) auxiliary data files, we provide extensive control over rendering the
+numbers of these elements when they are recalled (like in tables of contents).
+So, if you really want to use different texts for all references to a chapter
+header, it can be done:
+
+\starttyping
+\startchapter
+  [label=emcsquare,
+   title={About $e=mc^2$},
+   bookmark={einstein},
+   list={About $e=mc^2$ (Einstein)},
+   reference={$e=mc^2$}]
+
+  ... content ...
+
+\stopchapter
+\stoptyping
+
+Under the hood, the \MKIV\ code base is becoming quite a mix and once we have a
+more clear picture of where we're heading, it might become even more of a hybrid.
+Already for some time most of the font handling is done by \LUA, and a bit more
+logic and management might move to \LUA\ as well. However, as we want to be
+downward compatible we cannot go as far as we want (yet). This might change as
+soon as more of the primitives have associated \LUA\ functions. Even then it will
+be a trade off: calling \LUA\ takes some time and it might not pay off at all.
+
+Some of the more tricky components, like vertical spacing, grid snapping,
+balancing columns, etc.\ are already in the process of being \LUA fied and their
+hybrid form might turn into complete \LUA\ driven solutions eventually. Again,
+the compatibility issue forces us to follow a stepwise approach, but at the cost
+of (quite some) extra development time. But whatever happens, the \TEX\ input
+language as well as machinery will be there.
+
+\stopsection
+
+\startsection[title={\METAPOST}]
+
+I never regret integrating \METAPOST\ support in \CONTEXT\ and a dream came true
+when \MPLIB\ became part of \LUATEX. Apart from a few minor changes in the way
+text integrates into \METAPOST\ graphics the user interface in \MKIV\ is the same
+as in \MKII. Insofar as \LUA\ is involved, this is hidden from the user. We use
+\LUA\ for managing runs and conversion of the result to \PDF. Currently
+generating \METAPOST\ code by \LUA\ is limited to assisting in the typesetting of
+chemical structure formulas which is now part of the core.
+
+When defining graphics we use the \METAPOST\ language and not some \TEX|-|like
+variant of it. Information can be passed to \METAPOST\ using special macros (like
+\type {\MPcolor}), but most relevant status information is passed automatically
+anyway.
+
+You should not be surprised if at some point we can request information from
+\TEX\ directly, because after all this information is accessible. Think of
+something \type {w := texdimen(0) ;} being expanded at the \METAPOST\ end instead
+of \type {w := \the\dimen0 ;} being passed to \METAPOST\ from the \TEX\ end.
+
+\stopsection
+
+\startsection[title={\LUA}]
+
+What will the user see of \LUA ? First of all he or she can use this scripting
+language to generate content. But when making a format or by looking at the
+statistics printed at the end of a run, it will be clear that \LUA\ is used all
+over the place.
+
+So how about \LUA\ as a replacement for the \TEX\ input language? Actually, it is
+already possible to make such \quotation {\CONTEXT\ \LUA\ Documents} using
+\MKIV's built in functions. Each \CONTEXT\ command is also available as a \LUA\
+function.
+
+\startbuffer
+\startluacode
+  context.bTABLE {
+      framecolor = "blue",
+      align= "middle",
+      style = "type",
+      offset=".5ex",
+    }
+    for i=1,10 do
+      context.bTR()
+      for i=1,20 do
+        local r= math.random(99)
+        if r < 50 then
+          context.bTD {
+            background = "color",
+            backgroundcolor = "blue"
+          }
+          context(context.white("%#2i",r))
+        else
+          context.bTD()
+          context("%#2i",r)
+        end
+        context.eTD()
+      end
+      context.eTR()
+    end
+  context.eTABLE()
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Of course it helps if you know \CONTEXT\ a bit. For instance we can as well say:
+
+\starttyping
+if r < 50 then
+  context.bTD {
+    background = "color",
+    backgroundcolor = "blue",
+    foregroundcolor = "white",
+  }
+else
+  context.bTD()
+end
+context("%#2i",r)
+context.eTD()
+\stoptyping
+
+And, knowing \LUA\ helps as well, since the following is more efficient:
+
+\startbuffer
+\startluacode
+  local colored = {
+    background = "color",
+    backgroundcolor = "blue",
+    foregroundcolor = "white",
+  }
+  local basespec = {
+    framecolor = "blue",
+    align= "middle",
+    style = "type",
+    offset=".5ex",
+  }
+  local bTR, eTR = context.bTR, context.eTR
+  local bTD, eTD = context.bTD, context.eTD
+  context.bTABLE(basespec)
+    for i=1,10 do
+      bTR()
+      for i=1,20 do
+        local r= math.random(99)
+        bTD((r < 50 and colored) or nil)
+        context("%#2i",r)
+        eTD()
+      end
+      eTR()
+    end
+  context.eTABLE()
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Since in practice the speedup is negligible and the memory footprint is about the
+same, such optimization seldom make sense.
+
+At some point this interface will be extended, for instance when we can use
+\TEX's main (scanning, parsing and processing) loop as a so-called coroutine and
+when we have opened up more of \TEX's internals. Of course, instead of putting
+this in your \TEX\ source, you can as well keep the code at the \LUA\ end.
+
+\placefigure
+  {The result of the shown \LUA\ code.}
+  {\getbuffer}
+
+The script that manages a \CONTEXT\ run (also called \type {context}) will
+process files with the \type {cld} suffix automatically. You can also force
+processing as \LUA\ with the flag \type {--forcecld}. \footnote {Similar methods
+exist for processing \XML\ files.} The \type {mtxrun} script also recognizes
+\type {cld} files and delegate the call to the \type {context} script.
+
+\starttyping
+context yourfile.cld
+\stoptyping
+
+But will this replace \TEX\ as an input language? This is quite unlikely because
+coding documents in \TEX\ is so convenient and there is not much to gain here. Of
+course in a pure \LUA\ based workflow (for instance publishing information from
+databases) it would be nice to code in \LUA, but even then it's mostly syntactic
+sugar, as \TEX\ has to do the job anyway. However, eventually we will have a
+quite mature \LUA\ counterpart.
+
+\stopsection
+
+\startsection[title={\XML}]
+
+This is not so much a programming language but more a method of tagging your
+document content (or data). As structure is rather dominant in \XML, it is quite
+handy for situations where we need different output formats and multiple tools
+need to process the same data. It's also a standard, although this does not mean
+that all documents you see are properly structured. This in turn means that we
+need some manipulative power in \CONTEXT, and that happens to be easier to do in
+\MKIV\ than in \MKII.
+
+In \CONTEXT\ we have been supporting \XML\ for a long time, and in \MKIV\ we made
+the switch from stream based to tree based processing. The current implementation
+is mostly driven by what has been possible so far but as \LUATEX\ becomes more
+mature, bits and pieces will be reimplemented (or at least cleaned up and brought
+up to date with developments in \LUATEX).
+
+One could argue that it makes more sense to use \XSLT\ for converting \XML\ into
+something \TEX, but in most of the cases that I have to deal with much effort
+goes into mapping structure onto a given layout specification. Adding a bit of
+\XML\ to \TEX\ mapping to that directly is quite convenient. The total amount of
+code is probably smaller and it saves a processing step.
+
+We're mostly dealing with education|-|related documents and these tend to have a
+more complex structure than the final typeset result shows. Also, readability of
+code is not served with such a split as most mappings look messy anyway (or
+evolve that way) due to the way the content is organized or elements get abused.
+
+There is a dedicated manual for dealing with \XML\ in \MKIV, so we only show a
+simple example here. The documents to be processed are loaded in memory and
+serialized using setups that are associated to elements. We keep track of
+documents and nodes in a way that permits multipass data handling (rather usual
+in \TEX). Say that we have a document that contains questions. The following
+definitions will flush the (root element) \type {questions}:
+
+\starttyping
+\startxmlsetups xml:mysetups
+    \xmlsetsetup{#1}{questions}{xml:questions}
+\stopxmlsetups
+
+\xmlregistersetup{xml:mysetups}
+
+\startxmlsetups xml:questions
+    \xmlflush{#1}
+\stopxmlsetups
+
+\xmlprocessfile{main}{somefile.xml}{}
+\stoptyping
+
+Here the \type {#1} represents the current \XML\ element. Of course we need more
+associations in order to get something meaningful. If we just serialize then we
+have mappings like:
+
+\starttyping
+\xmlsetsetup{#1}{question|answer}{xml:*}
+\stoptyping
+
+So, questions and answers are mapped onto their own setup which flushes them,
+probably with some numbering done at the spot.
+
+In this mechanism \LUA\ is sort of invisible but quite busy as it is responsible
+for loading, filtering, accessing and serializing the tree. In this case \TEX\
+and \LUA\ hand over control in rapid succession.
+
+You can hook in your own functions, like:
+
+\starttyping
+\xmlfilter{#1}{(wording|feedback|choice)/function(cleanup)}
+\stoptyping
+
+In this case the function \type {cleanup} is applied to elements with names that
+match one of the three given. \footnote {This example is inspired by one of our
+projects where the cleanup involves sanitizing (highly invalid) \HTML\ data that
+is embedded as a \type {CDATA} stream, a trick to prevent the \XML\ file to be
+invalid.}
+
+Of course, once you start mixing in \LUA\ in this way, you need to know how we
+deal with \XML\ at the \LUA\ end. The following function show how we calculate
+scores:
+
+\starttyping
+\startluacode
+function xml.functions.totalscore(root)
+  local n = 0
+  for e in xml.collected(root,"/outcome") do
+    if xml.filter(e,"action[text()='add']") then
+      local m = xml.filter(e,"xml:///score/text()")
+      n = n + (tonumber(m or 0) or 0)
+    end
+  end
+  tex.write(n)
+end
+\stopluacode
+\stoptyping
+
+You can either use such a function in a filter or just use it as
+a \TEX\ macro:
+
+\starttyping
+\startxmlsetups xml:question
+  \blank
+  \xmlfirst{#1}{wording}
+  \startitemize
+    \xmlfilter{#1}{/answer/choice/command(xml:answer:choice)}
+  \stopitemize
+  \endgraf
+  score: \xmlfunction{#1}{totalscore}
+  \blank
+\stopxmlsetups
+
+\startxmlsetups xml:answer:choice
+    \startitem
+        \xmlflush{#1}
+    \stopitem
+\stopxmlsetups
+\stoptyping
+
+The filter variant is like this:
+
+\starttyping
+\xmlfilter{#1}{./function('totalscore')}
+\stoptyping
+
+So you can take your choice and make your source look more \XML|-|ish,
+\LUA|-|like or \TEX|-|wise. A careful reader might have noticed the peculiar
+\type {xml://} in the function code. When used inside \MKIV, the serializer
+defaults to \TEX\ so results are piped back into \TEX. This prefix forced the
+regular serializer which keeps the result at the \LUA\ end.
+
+Currently some of the \XML\ related modules, like \MATHML\ and handling of
+tables, are really a mix of \TEX\ code and \LUA\ calls, but it makes sense to
+move them completely to \LUA. One reason is that their input (formulas and table
+content) is restricted to non|-|\TEX\ anyway. On the other hand, in order to be
+able to share the implementation with \TEX\ input, it also makes sense to stick
+to some hybrid approach. In any case, more of the calculations and logic will
+move to \LUA, while \TEX\ will deal with the content.
+
+A somewhat strange animal here is \XSLFO. We do support it, but the \MKII\
+implementation was always somewhat limited and the code was quite complex. So,
+this needs a proper rewrite in \MKIV, which will happen indeed. It's mostly a
+nice exercise of hybrid technology but until now I never really needed it. Other
+bits and pieces of the current \XML\ goodies might also get an upgrade.
+
+There is already a bunch of functions and macros to filter and manipulate \XML\
+content and currently the code involved is being cleaned up. What direction we go
+also depends on users' demands. So, with respect to \XML\ you can expect more
+support, a better integration and an upgrade of some supported \XML\ related
+standards.
+
+\startsection [title={Tools}]
+
+Some of the tools that ship with \CONTEXT\ are also examples of hybrid usage.
+
+Take this:

+
+The \type {mtxrun} script is a \LUA\ script that acts as a controller for other
+scripts, in this case \type {mtx-server.lua} that is part of the regular
+distribution. As we use \LUATEX\ as a \LUA\ interpreter and since \LUATEX\ has a
+socket library built in, it can act as a web server, limited but quite right for
+our purpose. \footnote {This application is not intentional but just a side
+effect.}
+
+The web page that pops up when you enter the given address lets you currently
+choose between the \CONTEXT\ help system and a font testing tool. In \in {figure}
+[fig:fonttest] you seen an example of what the font testing tool does.
+
+\placefigure
+  [here]
+  [fig:fonttest]
+  {An example of using the font tester.}
+  {\externalfigure[mtx-server-ctx-fonttest.png][width=\textwidth]}
+
+Here we have \LUATEX\ running a simple web server but it's not aware of having
+\TEX\ on board. When you click on one of the buttons at the bottom of the screen,
+the server will load and execute a script related to the request and in this case
+that script will create a \TEX\ file and call \LUATEX\ with \CONTEXT\ to process
+that file. The result is piped back to the browser.
+
+You can use this tool to investigate fonts (their bad and good habits) as well as
+to test the currently available \OPENTYPE\ functionality in \MKIV\ (bugs as well
+as goodies).
+
+So again we have a hybrid usage although in this case the user is not confronted
+with \LUA\ and|/|or \TEX\ at all. The same is true for the other goodie, shown in
+\in {figure} [fig:help]. Actually, such a goodie has always been part of the
+\CONTEXT\ distribution but it has been rewritten in \LUA.
+
+\placefigure
+  [here]
+  [fig:help]
+  {An example of a help screen for a command.}
+  {\externalfigure[mtx-server-ctx-help.png][width=\textwidth]}
+
+The \CONTEXT\ user interface is defined in an \XML\ file, and this file is used
+for several purposes: initializing the user interfaces at format generation time,
+typesetting the formal command references (for all relevant interface languages),
+for the wiki, and for the mentioned help goodie.
+
+Using the mix of languages permits us to provide convenient processing of
+documents that otherwise would demand more from the user than it does now. For
+instance, imagine that we want to process a series of documents in the
+so|-|called \EPUB\ format. Such a document is a zipped file that has a
+description and resources. As the content of this archive is prescribed it's
+quite easy to process it:
+
+\starttyping
+context --ctx=x-epub.ctx yourfile.epub
+\stoptyping
+
+This is equivalent to:
+
+\starttyping
+texlua mtxrun.lua --script context --ctx=x-epub.ctx yourfile.epub
+\stoptyping
+
+So, here we have \LUATEX\ running a script that itself (locates and) runs a
+script \type {context}. That script loads a \CONTEXT\ job description file (with
+suffix \type {ctx}). This file tells what styles to load and might have
+additional directives but none of that has to bother the end user. In the
+automatically loaded style we take care of reading the \XML\ files from the
+zipped file and eventually map the embedded \HTML\ like files onto style elements
+and produce a \PDF\ file. So, we have \LUA\ managing a run and \MKIV\ managing
+with help of \LUA\ reading from zip files and converting \XML\ into something
+that \TEX\ is happy with. As there is no standard with respect to the content
+itself, i.e.\ the rendering is driven by whatever kind of structure is used and
+whatever the \CSS\ file is able to map it onto, in practice we need an additional
+style for this class of documents. But anyway it's a good example of integration.
+
+\stopsection
+
+\startsection [title={The future}]
+
+Apart from these language related issues, what more is on the agenda? To mention
+a few integration related thoughts:
+
+\startitemize[packed]
+
+\startitem
+    At some point I want to explore the possibility to limit processing to just
+    one run, for instance by doing trial runs without outputting anything but
+    still collecting multipass information. This might save some runtime in
+    demanding workflows especially when we keep extensive font loading and image
+    handling in mind.
+\stopitem
+
+\startitem
+    Related to this is the ability to run \MKIV\ as a service but that demands
+    that we can reset the state of \LUATEX\ and actually it might not be worth
+    the trouble at all given faster processors and disks. Also, it might not save
+    much runtime on larger jobs.
+\stopitem
+
+\startitem
+    More interesting can be to continue experimenting with isolating parts of
+    \CONTEXT\ in such a way that one can construct a specialized subset of
+    functionality. Of course the main body of code will always be loaded as one
+    needs basic typesetting anyway.
+\stopitem
+
+\stopitemize
+
+Of course we keep improving existing mechanisms and improve solutions using a mix
+of \TEX\ and \LUA, using each language (and system) for what it can do best.

+\startchapter[title={Handling math: A retrospective}]
+
+{This is \TUGBOAT\ article .. reference needed.}
+
+% In this article I will reflect on how the plain \TEX\ approach to math
+% fonts influenced the way math has been dealt with in \CONTEXT\ \MKII\
+% and why (and how) we divert from it in its follow up \MKIV, now that
+% \LUATEX\ and \OPENTYPE\ math have come around.
+
+When you start using \TEX, you cannot help but notice that math plays an
+important role in this system. As soon as you dive into the code you will see
+that there is a concept of families that is closely related to math typesetting.
+A family is a set of three sizes: text, script and scriptscript.
+
+\startformula
+a^{b^{c}} = \frac{d}{e}
+\stopformula
+
+The smaller sizes are used in superscripts and subscripts and in more complex
+formulas where information is put on top of each other.
+
+It is no secret that the latest math font technology is not driven by the \TEX\
+community but by Microsoft. They have taken a good look at \TEX\ and extended the
+\OPENTYPE\ font model with the information that is needed to do things similar to
+\TEX\ and beyond. It is a firm proof of \TEX's abilities that after some 30 years
+it is still seen as the benchmark for math typesetting. One can only speculate
+what Don Knuth would have come up with if today's desktop hardware and printing
+technology had been available in those days.
+
+As a reference implementation of a font Microsoft provides Cambria Math. In the
+specification the three sizes are there too: a font can provide specifically
+designed script and scriptscript variants for text glyphs where that is relevant.
+Control is exercised with the \type {ssty} feature.
+
+Another inheritance from \TEX\ and its fonts is the fact that larger symbols can
+be made out of snippets and these snippets are available as glyphs in the font,
+so no special additional (extension) fonts are needed to get for instance really
+large parentheses. The information of when to move up one step in size (given
+that there is a larger shape available) or when and how to construct larger
+symbols out of snippets is there as well. Placement of accents is made easy by
+information in the font and there are a whole lot of parameters that control the
+typesetting process. Of course you still need machinery comparable to \TEX's math
+subsystem but Microsoft Word has such capabilities.
+
+I'm not going to discuss the nasty details of providing math support in \TEX, but
+rather pay some attention to an (at least for me) interesting side effect of
+\TEX's math machinery. There are excellent articles by Bogus\l{}aw Jackowski and
+Ulrik Vieth about how \TEX\ constructs math and of course Knuth's publications
+are the ultimate source of information as well.
+
+Even if you only glance at the implementation of traditional \TEX\ font support,
+the previously mentioned families are quite evident. You can have 16 of them but
+4 already have a special role: the upright roman font, math italic, math symbol
+and math extension. These give us access to some 1000 glyphs in theory, but when
+\TEX\ showed up it was mostly a 7-bit engine and input of text was often also
+7-bit based, so in practice many fewer shapes are available, and subtracting the
+snippets that make up the large symbols brings down the number again.
+
+Now, say that in a formula you want to have a bold character. This character is
+definitely not in the 4 mentioned families. Instead you enable another one, one
+that is linked to a bold font. And, of course there is also a family for bold
+italic, slanted, bold slanted, monospaced, maybe smallcaps, sans serif, etc. To
+complicate things even more, there are quite a few symbols that are not covered
+in the foursome so we need another 2 or 3 families just for those. And yes, bold
+math symbols will demand even more families.
+
+\startformula
+a + \bf b + \bi c = \tt d + \ss e + \cal f
+\stopformula
+
+Try to imagine what this means for implementing a font system. When (in for
+instance \CONTEXT) you choose a specific body font at a certain size, you not
+only switch the regular text fonts, you also initialize math. When dealing with
+text and a font switch there, it is no big deal to delay font loading and
+initialization till you really need the font. But for math it is different. In
+order to set up the math subsystem, the families need to be known and set up and
+as each one can have three members you can imagine that you easily initialize
+some 30 to 40 fonts. And, when you use several math setups in a document,
+switching between them involves at least some re-initialization of those
+families.
+
+When Taco Hoekwater and I were discussing \LUATEX\ and especially what was needed
+for math, it was sort of natural to extend the number of families to 256. After
+all, years of traditional usage had demonstrated that it was pretty hard to come
+up with math font support where you could freely mix a whole regular and a whole
+bold set of characters simply because you ran out of families. This is a side
+effect of math processing happening in several passes: you can change a family
+definition within a formula, but as \TEX\ remembers only the family number, a
+later definition overloads a previous one. The previous example in a traditional
+\TEX\ approach can result in:
+
+\starttyping
+a + \fam7 b + \fam8 c = \fam9 d + \fam10 e + \fam11 f
+\stoptyping
+
+Here the \type{a} comes from the family that reflects math italic (most likely
+family~1) and \type {+} and \type {=} can come from whatever family is told to
+provide them (this is driven by their math code properties). As family numbers
+are stored in the identification pass, and in the typesetting pass resolve to
+real fonts you can imagine that overloading a family in the middle of a
+definition is not an option: it's the number that gets stored and not what it is
+bound to. As it is unlikely that we actually use more than 16 families we could
+have come up with a pool approach where families are initialized on demand but
+that does not work too well with grouping (or at least it complicates matters).
+
+So, when I started thinking of rewriting the math font support for \CONTEXT\
+\MKIV, I still had this nicely increased upper limit in mind, if only because I
+was still thinking of support for the traditional \TEX\ fonts. However, I soon
+realized that it made no sense at all to stick to that approach: \OPENTYPE\ math
+was on its way and in the meantime we had started the math font project. But
+given that this would easily take some five years to finish, an intermediate
+solution was needed. As we can make virtual fonts in \LUATEX, I decided to go
+that route and for several years already it has worked quite well. For the moment
+the traditional \TEX\ math fonts (Computer Modern, px, tx, Lucida, etc) are
+virtualized into a pseudo|-|\OPENTYPE\ font that follows the \UNICODE\ math
+standard. So instead of needing more families, in \CONTEXT\ we could do with
+less. In fact, we can do with only two: one for regular and one for bold,
+although, thinking of it, there is nothing that prevents us from mixing different
+font designs (or preferences) in one formula but even then a mere four families
+would still be fine.
+
+To summarize this, in \CONTEXT\ \MKIV\ the previous example now becomes:
+
+\starttyping
+U+1D44E + U+1D41B + 0x1D484 = U+1D68D + U+1D5BE + U+1D4BB
+\stoptyping
+
+For a long time I have been puzzled by the fact that one needs so many fonts for
+a traditional setup. It was only after implementing the \CONTEXT\ \MKIV\ math
+subsystem that I realized that all of this was only needed in order to support
+alphabets, i.e.\ just a small subset of a font. In \UNICODE\ we have quite a few
+math alphabets and in \CONTEXT\ we have ways to map a regular keyed-in (say)
+\quote{a} onto a bold or monospaced one. When writing that code I hadn't even
+linked the \UNICODE\ math alphabets to the family approach for traditional \TEX.
+Not being a mathematician myself I had no real concept of systematic usage of
+alternative alphabets (apart from the occasional different shape for an
+occasional physics entity).
+
+Just to give an idea of what \UNICODE\ defines: there are alphabets in regular
+(upright), bold, italic, bold italic, script, bold script, fraktur, bold fraktur,
+double|-|struck, sans|-|serif, sans|-|serif bold, sans|-|serif italic,
+sans|-|serif bold italic and monospace. These are regular alphabets with upper-
+and lowercase characters complemented by digits and occasionally Greek.
+
+It was a few years later (somewhere near the end of 2010) that I realized that a
+lot of the complications in (and load on) a traditional font system were simply
+due to the fact that in order to get one bold character, a whole font had to be
+loaded in order for families to express themselves. And that in order to have
+several fonts being rendered, one needed lots of initialization for just a few
+cases. Instead of wasting one font and family for an alphabet, one could as well
+have combined 9 (upper and lowercase) alphabets into one font and use an offset
+to access them (in practice we have to handle the digits too). Of course that
+would have meant extending the \TEX\ math machinery with some offset or
+alternative to some extensive mathcode juggling but that also has some overhead.
+
+If you look at the plain \TEX\ definitions for the family related matters, you
+can learn a few things. First of all, there are the regular four families
+defined:
+
+\starttyping
+\textfont0=\tenrm \scriptfont0=\sevenrm \scriptscriptfont0=\fiverm
+\textfont1=\teni  \scriptfont1=\seveni  \scriptscriptfont1=\fivei
+\textfont2=\tensy \scriptfont2=\sevensy \scriptscriptfont2=\fivesy
+\textfont3=\tenex \scriptfont3=\tenex   \scriptscriptfont3=\tenex
+\stoptyping
+
+Each family has three members. There are some related definitions
+as well:
+
+\starttyping
+\def\rm      {\fam0\tenrm}
+\def\mit     {\fam1}
+\def\oldstyle{\fam1\teni}
+\def\cal     {\fam2}
+\stoptyping
+
+So, with \type {\rm} you not only switch to a family (in math mode) but you also
+enable a font. The same is true for \type {\oldstyle} and this actually brings us
+to another interesting side effect. The fact that oldstyle numerals come from a
+math font has implications for the way this rendering is supported in macro
+packages. As naturally all development started when \TEX\ came around, package
+design decisions were driven by the basic fact that there was only one math font
+available. And, as a consequence most users used the Computer Modern fonts and
+therefore there was never a real problem in getting those oldstyle characters in
+your document.
+
+However, oldstyle figures are a property of a font design (like table digits) and
+as such not specially related to math. And, why should one tag each number then?
+Of course it's good practice to tag extensively (and tagging makes switching
+fonts easy) but to tag each number is somewhat over the top. When more fonts
+(usable in \TEX) became available it became more natural to use a proper oldstyle
+font for text and the \type {\oldstyle} more definitely ended up as a math
+command. This was not always easy to understand for users who primarily used
+\TEX\ for anything but math.
+
+Another interesting aspect is that with \OPENTYPE\ fonts oldstyle figures are
+again an optional feature, but now at a different level. There are a few more
+such traditional issues: bullets often come from a math font as well (which works
+out ok as they have nice, not so tiny bullets). But the same is true for
+triangles, squares, small circles and other symbols. And, to make things worse,
+some come from the regular \TEX\ math fonts, and others from additional ones,
+like the \AMS\ symbols. Again, \OPENTYPE\ and \UNICODE\ will change this as now
+these symbols are quite likely to be found in fonts as they have a larger
+repertoire of shapes.
+
+From the perspective of going from \MKII\ to \MKIV\ it boils down to changing old
+mechanisms that need to handle all this (dependent on the availability of fonts)
+to cleaner setups. Of course, as fonts are never completely consistent, or
+complete for that matter, and features can be implemented incorrectly or
+incompletely we still end up with issues, but (at least in \CONTEXT) dealing with
+that has been moved to runtime manipulation of the fonts themselves (as part of
+the so-called font goodies).
+
+Back to the plain definitions, we now arrive at some new families:
+
+\starttyping
+\newfam\itfam \def\it{\fam\itfam\tenit}
+\newfam\slfam \def\sl{\fam\slfam\tensl}
+\newfam\bffam \def\bf{\fam\bffam\tenbf}
+\newfam\ttfam \def\tt{\fam\ttfam\tentt}
+\stoptyping
+
+The plain \TEX\ format was never meant as a generic solution but instead was an
+example of a macro set and serves as a basis for styles used by Don Knuth for his
+books. Nevertheless, in spite of the fact that \TEX\ was made to be extended,
+pretty soon it became frozen and the macros and font definitions that came with
+it became the benchmark. This might be the reason why \UNICODE\ now has a
+monospaced alphabet. Once you've added monospaced you might as well add more
+alphabets as for sure in some countries they have their own preferences.
+\footnote {At the Dante 2011 meeting we had interesting discussions during dinner
+about the advantages of using Sütterlinschrift for vector algebra and the
+possibilities for providing it in the upcoming \TeX\ Gyre math fonts.}
+
+As with \type {\rm}, the related commands are meant to be used in text as well.
+More interesting is to see what follows now:
+
+\starttyping
+\textfont        \itfam=\tenit
+\textfont        \slfam=\tensl
+
+\textfont        \bffam=\tenbf
+\scriptfont      \bffam=\sevenbf
+\scriptscriptfont\bffam=\fivebf
+
+\textfont        \ttfam=\tentt
+\stoptyping
+
+Only the bold definition has all members. This means that (regular) italic,
+slanted, and monospaced are not actually that much math at all. You will probably
+only see them in text inside a math formula. From this you can deduce that
+contrary to what I said before, these variants were not really meant for
+alphabets, but for text in which case we need complete fonts. So why do I still
+conclude that we don't need all these families? In practice text inside math is
+not always done this way but with a special set of text commands. This is a
+consequence of the fact that when we add text, we want to be able to do so in
+each language with even language|-|specific properties supported. And, although a
+family switch like the above might do well for English, as soon as you want
+Polish (extended Latin), Cyrillic or Greek you definitely need more than a family
+switch, if only because encodings come into play. In that respect it is
+interesting that we do have a family for monospaced, but that \type {\Im} and
+\type {\Re} have symbolic names, although a more extensive setup can have a
+blackboard family switch.
+
+By the way, the fact that \TEX\ came with italic alongside slanted also has some
+implications. Normally a font design has either italic or something slanted (then
+called oblique). But, Computer Modern came with both, which is no surprise as
+there is a metadesign behind it. And therefore macro packages provide ways to
+deal with those variants alongside. I wonder what would have happened if this had
+not been the case. Nowadays there is always this regular, italic (or oblique),
+bold and bold italic set to deal with, and the whole set can become lighter or
+bolder.
+
+In \CONTEXT\ \MKII, however, the set is larger as we also have slanted and bold
+slanted and even smallcaps, so most definition sets have 7~definitions instead
+of~4. By the way, smallcaps is also special. if Computer Modern had had smallcaps
+for all variants, support for them in \CONTEXT\ undoubtedly would have been kept
+out of the mentioned~7 but always been a new typeface definition (i.e.\ another
+fontclass for insiders). So, when something would have to be smallcaps, one would
+simply switch the whole lot to smallcaps (bold smallcaps, etc.). Of course this
+is what normally happens, at least in my setups, but nevertheless one can still
+find traces of this original Computer Modern|-|driven approach. And now we are at
+it: the whole font system still has the ability to use design sizes and combine
+different ones in sets, if only because in Computer Modern you don't have all
+sizes. The above definitions use ten, seven and five, but for instance for an
+eleven point set up you need to creatively choose the proper originals and scale
+them to the right family size. Nowadays only a few fonts ship with multiple
+design sizes, and although some can be compensated with clever hinting it is a
+pity that we can apply this mechanism only to the traditional \TEX\ fonts.
+
+Concerning the slanting we can remark that \TEX ies are so fond of this that they
+even extended the \TEX\ engines to support slanting in the core machinery (or
+more precisely in the backend while the frontend then uses adapted metrics). So,
+slanting is available for all fonts.
+
+This brings me to another complication in writing a math font subsystem: bold.
+During the development of \CONTEXT\ \MKII\ I was puzzled by the fact that user
+demands with respect to bold were so inconsistent. This is again related to the
+way a somewhat simple setup looks: explicitly switching to bold characters or
+symbols using a \type {\bf} (alike) switch. This works quite well in most cases,
+but what if you use math in a section title? Then the whole lot should be in bold
+and an embedded bold symbol should be heavy (i.e.\ more bold than bold). As a
+consequence (and due to limited availability of complete bold math fonts) in
+\MKII\ there are several bold strategies implemented.
+
+However, in a \UNICODE\ universe things become surprisingly easy as \UNICODE\
+defines those symbols that have bold companions (whatever you want to call them,
+mostly math alphanumerics) so a proper math font has them already. This limited
+subset is often available in a font collection and font designers can stick to
+that subset. So, eventually we get one regular font (with some bold glyphs
+according to the \UNICODE\ specification) and a bold companion that has heavy
+variants for those regular bold shapes.
+
+The simple fact that \UNICODE\ distinguishes regular and bold simplifies an
+implementation as it's easier to take that as a starting point than users who for
+all their goodwill see only their small domain of boldness.
+
+It might sound like \UNICODE\ solves all our problems but this is not entirely
+true. For instance, the \UNICODE\ principle that no character should be there
+more than once has resulted in holes in the \UNICODE\ alphabets, especially
+Greek, blackboard, fraktur and script. As exceptions were made for non|-|math I
+see no reason why the few math characters that now put holes in an alphabet could
+not have been there. As with more standards, following some principles too
+strictly eventually results in all applications that follow the standard having
+to implement the same ugly exceptions explicitly. As some standards aim for
+longevity I wonder how many programming hours will be wasted this way.
+
+This brings me to the conclusion that in practice 16 families are more than
+enough in a \UNICODE|-|aware \TEX\ engine especially when you consider that for a
+specific document one can define a nice set of families, just as in plain \TEX.
+It's simply the fact that we want to make a macro package that does it all and
+therefore has to provide all possible math demands into one mechanism that
+complicates life. And the fact that \UNICODE\ clearly demonstrates that we're
+only talking about alphabets has brought (at least) \CONTEXT\ back to its basics:
+a relatively simple, few|-|family approach combined with a dedicated alphabet
+selection system. Of course eventually users may come up with new demands and we
+might again end up with a mess. After all, it's the fact that \TEX\ gives us
+control that makes it so much fun.

+\startchapter[title={Exporting math}]
+
+\startsection [title={Introduction}]
+
+As \CONTEXT\ has an \XML\ export feature and because \TEX\ is often strongly
+associated with math typesetting, it makes sense to take a look at coding and
+exporting math. In the next sections some aspects are discussed. The examples
+shown are a snaphot of the possibilities around June 2011.
+
+\stopsection
+
+\startsection [title={Encoding the math}]
+
+In \CONTEXT\ there are several ways to input math. In the following example we
+will use some bogus math with enough structure to get some interesting results.
+
+The most natural way to key in math is using the \TEX\ syntax. Of course you need
+to know the right commands for accessing special symbols, but if you're familiar
+with a certain domain, this is not that hard.
+
+\startbuffer
+\startformula
+  \frac { x \geq 2 } { y \leq 4 }
+\stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+When you have an editor that can show more than \ASCII\ the following also works
+out well.
+
+\starttyping
+\startformula
+  \frac { x ≥ 2 } { y ≤ 4 }
+\stopformula
+\stoptyping
+
+One can go a step further and use the proper math italic alphabet but there are
+hardly any (monospaced) fonts out there that can visualize it.
+
+\starttyping[escape=yes]
+\startformula
+  \frac { /BTEX\it x/ETEX ≥ 2 } { /BTEX\it y/ETEX ≤ 4 }
+\stopformula
+\stoptyping
+
+Anyhow, \CONTEXT\ is quite capable of remapping the regular alphabets onto the
+real math ones, so you can stick to \type {x} and \type {y}.
+
+Another way to enter the same formula is by using what we call calculator math.
+We came up with this format many years ago when \CONTEXT\ had to process student
+input using a syntax similar to what the calculators they use at school accept.
+
+\startbuffer
+\startformula
+  \calcmath{(x >= 2)/(y <= 4)}
+\stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+As \CONTEXT\ is used in a free and open school math project, and because some of
+our projects mix \MATHML\ into \XML\ encoded sources, we can also consider using
+\MATHML. The conceptually nicest way is to use content markup, where the focus is
+on meaning and interchangability and not on rendering. However, we can render it

+\stoptyping
+
+This is pretty close to what we have entered as presentation \MATHML. The main
+difference is that the (display or inline) mode is registered as attribute and
+that entities have been resolved to \UTF. Of course one could use \UTF\ directly
+in the input.
+
+\stopsection
+
+\startsection [title={Parsing the input}]
+
+In \TEX\ typesetting math happens in two stages. First the input is parsed and
+converted into a so called math list. In the following case it's a rather linear
+list, but in the case of a fraction it is a tree.
+
+\startbuffer
+\startformula
+  x = - 1.23
+\stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+A naive export looks as follows. The sequence becomes an \type {mrow}:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:mi>/BTEX\it x/ETEX</m:mi>
+    <m:mo>=</m:mo>
+    <m:mo>−</m:mo>
+    <m:mn>1</m:mn>
+    <m:mo>.</m:mo>
+    <m:mn>2</m:mn>
+    <m:mn>3</m:mn>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+However, we can clean this up without too much danger of getting invalid output:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:mi>/BTEX\it x/ETEX</m:mi>
+    <m:mo>=</m:mo>
+    <m:mo>−</m:mo>
+    <m:mn>1.23</m:mn>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+This is still not optimal, as one can argue that the minus sign is part of the
+number. This can be taken care of at the input end:
+
+\startbuffer
+\startformula
+  x = \mn{- 1.23}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+Now we get:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:mi>/BTEX\it x/ETEX</m:mi>
+    <m:mo>=</m:mo>
+    <m:mn>−1.23</m:mn>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+Tagging a number makes sense anyway, for instance when we use different numbering
+schemes:
+
+\startbuffer
+\startformula
+  x = \mn{0x20DF} = 0x20DF
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+We get the first number nicely typeset in an upright font but the second one
+becomes a mix of numbers and identifiers:
+
+\getbuffer
+
+This is nicely reflected in the export:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:mi>/BTEX\it x/ETEX</m:mi>
+    <m:mo>=</m:mo>
+    <m:mn>0x20DF</m:mn>
+    <m:mo>=</m:mo>
+    <m:mn>0</m:mn>
+    <m:mi>/BTEX\it x/ETEX</m:mi>
+    <m:mn>20</m:mn>
+    <m:mi>/BTEX\it D/ETEX</m:mi>
+    <m:mi>/BTEX\it F/ETEX</m:mi>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+In a similar fashion we can use \type {\mo} and \type {\mi} although these are
+seldom needed, if only because characters and symbols already carry these
+properties with them.
+
+\stopsection
+
+\startsection [title={Enhancing the math list}]
+
+When the input is parsed into a math list the individual elements are called
+noads. The most basic noad has pointers to a nucleus, a superscript and a
+subscript and each of them can be the start of a sublist. All lists (with more
+than one character) are quite similar to \type {mrow} in \MATHML. In the export
+we do some flattening because otherwise we would get too many redundant \type
+{mrow}s, not that it hurts but it saves bytes.
+
+\startbuffer
+\startformula
+  x_n^2
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+This renders as:
+
+\getbuffer
+
+And it gets exported as:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:msubsup>
+      <m:mi>/BTEX\it x/ETEX</m:mi>
+      <m:mi>/BTEX\it n/ETEX</m:mi>
+      <m:mn>2</m:mn>
+    </m:msubsup>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+As said, in the math list this looks more or less the same: we have a noad with a
+nucleus pointing to a math character (\type {x}) and two additional pointers to
+the sub- and superscripts.
+
+After this math list is typeset, we will end up with horizontal and vertical
+lists with glyphs, kerns, glue and other nodes. In fact we end up with what can
+be considered regular references to slots in a font mixed with positioning
+information. In the process the math properties gets lost. This happens between
+step~3 and~4 in the next overview.

+In \CONTEXT\ \MKIV\ we intercept the math list (with noads) and apply a couple of
+manipulations to it, most noticeably relocation of characters. Last in the
+(currently some 10) manipulation passes over the math list comes tagging. This
+only happens when the export is active or when we produce tagged pdf. \footnote
+{Currently the export is the benchmark and the tagged \PDF\ implementation
+follows, so there can be temporary incompatibilities.}
+
+By tagging the recognizable math snippets we can later use those persistent
+properties to reverse engineer the \MATHML\ from the input.
+
+\stopsection
+
+\startsection [title={Intercepting the typeset content}]
+
+When a page gets shipped out, we also convert the typeset content to an
+intermediate form, ready for export later on. Version 0.22 of the exporter has a
+rather verbose tracing mechanism and the simple example with sub- and superscript
+is reported as follows:

+\stoptyping
+
+This is not yet what we want so some more effort is needed in order to get proper
+\MATHML.
+
+\stopsection
+
+\startsection [title={Exporting the result}]
+
+The report that we showed before representing the simple example with super- and
+subscripts is strongly related to the visual rendering. It happens that \TEX\
+first typesets the superscript and then deals with the subscript. Some spacing is
+involved which shows up in the report between the two scripts.
+
+In \MATHML\ we need to swap the order of the scripts, so effectively we need:
+
+\starttyping[escape=yes]
+<math-8 trigger='268' index='1'>
+  <mrow-20 trigger='268' index='1'>
+    <msubsup-1 trigger='268' index='1'>
+      <mi-15 trigger='268' index='1'>
+        /BTEX\it x/ETEX
+      </mi-15>
+      <mi-16 trigger='269' index='2'>
+        /BTEX\it n/ETEX
+      </mi-16>
+      <mn-13 trigger='270' index='3'>
+        2
+      </mn-13>
+    </msubsup-1>
+  </mrow-20>
+</math-8>
+\stoptyping
+
+This swapping (and some further cleanup) is done before the final tree is written
+to a file. There we get:
+
+\starttyping[escape=yes]
+<m:math display="block">
+  <m:mrow>
+    <m:msubsup>
+      <m:mi>/BTEX\it x/ETEX</m:mi>

+      <m:mn>2</m:mn>
+    </m:msubsup>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+This looks pretty close to the intermediate format. In case you wonder with how
+much intermediate data we end up, the answer is: quite some. The reason will be
+clear: we intercept typeset output and reconstruct the input from that, which
+means that we have additional information travelling with the content. Also, we
+need to take crossing pages into account and we need to reconstruct paragraphs.
+There is also some overhead in making the \XML\ look acceptable but that is
+neglectable. In terms of runtime, the overhead of an export (including tagging)
+is some 10\% which is not that bad, and there is some room for optimization.
+
+\stopsection
+
+\startsection[title={Special treatments}]
+
+In content \MATHML\ the \type {apply} tag is the cornerstone of the definition.
+Because there is enough information the rendering mechanism can deduce when a
+function is applied and act accordingly when it comes to figuring out the right
+amount of spacing. In presentation \MATHML\ there is no such information and
+there the signal is given by putting a character with code \type {U+2061} between
+the function identifier and the argument. In \TEX\ input all this is dealt with
+in the macro that specifies a function but some ambiguity is left.
+
+Compare the following two formulas:
+
+\startbuffer
+\startformula
+  \tan = \frac { \sin } { \cos }
+\stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+In the export this shows up as follows:

+This time we get the function application signal in the output. We could add it

+In the future, we will extend the \type {\apply} macro to also deal with

+\stoptyping
+
+Watch how the equal sign ends up in the cell. Contrary to what you might expect,
+the relation symbols (currently) don't end up in their own column. Keep in mind
+that these tables look structured but that presentational \MATHML\ does not
+assume that much structure. \footnote {The spacing could be improved here but
+it's just an example, not something real.}
+
+\stopsection
+
+\startsection[title=Units]
+
+Rather early in the history of \CONTEXT\ we had support for units and the main
+reason for this was that we wanted consistent spacing. The input of the old
+method looks as follows:
+
+\starttyping
+10 \Cubic \Meter \Per \Second
+\stoptyping
+
+This worked in regular text as well as in math and we even have an \XML\ variant.
+A few years ago I played with a different method and the \LUA\ code has been
+laying around for a while but never made it into the \CONTEXT\ core. However,
+when playing with the export, I decided to pick up that thread. The verbose
+variant can now be coded as:
+
+\starttyping
+10 \unit{cubic meter per second}
+\stoptyping
+
+but equally valid is:
+
+\starttyping
+10 \unit{m2/s}
+\stoptyping
+
+and also
+
+\starttyping
+\unit{10 m2/s}
+\stoptyping
+
+is okay. So, one can use the short (often official) symbols as well as more
+verbose names. In order to see what gets output we cook up some bogus units.
+
+\startbuffer
+30 \unit{kilo pascal square meter / kelvin second}
+\stopbuffer
+
+\typebuffer
+
+This gets rendered as: \getbuffer. The export looks as follows:
+
+\starttyping
+30 <unit>kPa⋅m<sup>2</sup>/K⋅s</unit>
+\stoptyping
+
+\startbuffer
+\unit{30 kilo pascal square meter / kelvin second}
+\stopbuffer
+
+You can also say:
+
+\typebuffer
+
+and get: \getbuffer. This time the export looks like this:
+
+\starttyping
+<quantity>
+  <number>30</number>
+  <unit>kPa⋅m<sup>2</sup>/K⋅s</unit>
+</quantity>
+\stoptyping
+
+\startbuffer
+$30 \unit{kilo pascal square meter / kelvin second }$
+\stopbuffer
+
+When we use units in math, the rendering is mostly the same. So,
+
+\typebuffer
+
+Gives: \getbuffer, but the export now looks different:
+
+\starttyping
+<m:math display="inline">
+  <m:mrow>
+  <m:mn>30</m:mn>
+  <m:maction actiontype="unit">
+    <m:mrow>
+      <m:mi mathvariant="normal">k</m:mi>
+      <m:mi mathvariant="normal">P</m:mi>
+      <m:mi mathvariant="normal">a</m:mi>
+      <m:mo>⋅</m:mo>
+      <m:msup>
+          <m:mi mathvariant="normal">m</m:mi>
+          <m:mn>2</m:mn>
+      </m:msup>
+      <m:mo>/</m:mo>
+      <m:mi mathvariant="normal">K</m:mi>
+      <m:mo>⋅</m:mo>
+      <m:mi mathvariant="normal">s</m:mi>
+    </m:mrow>
+  </m:maction>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+Watch how we provide some extra information about it being a unit and how the
+rendering is controlled as by default a renderer could turn the \type {K} and
+other identifiers into math italic. Of course the subtle spacing is lost as we
+assume a clever renderer that can use the information provided in the \type
+{maction}.
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+So far the results of the export look quite acceptable. It is to be seen to what
+extent typographic detail will be added. Thanks to \UNICODE\ math we don't need
+to add style directives. Because we carry information with special spaces, we
+could add these details if needed but for the moment the focus is on getting the
+export robust on the one end, and extending \CONTEXT's math support with some
+additional structure.
+
+The export shows in the previous sections was not entirely honest: we didn't show
+the wrapper. Say that we have this:
+
+\startbuffer
+\startformula
+  e = mc^2
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+This shows up as:
+
+\getbuffer
+
+and exports as:
+
+\starttyping[escape=yes]
+<formula>
+  <formulacontent>
+    <m:math display="block">
+      <m:mrow>
+        <m:mi>/BTEX\it e/ETEX</m:mi>
+        <m:mo>=</m:mo>
+        <m:mi>/BTEX\it m/ETEX</m:mi>
+        <m:msup>
+          <m:mi>/BTEX\it c/ETEX</m:mi>
+          <m:mn>2</m:mn>
+        </m:msup>
+      </m:mrow>
+    </m:math>
+  </formulacontent>
+</formula>
+\stoptyping
+
+\startbuffer
+\placeformula
+  \startformula
+     e = mc^2
+  \stopformula
+\stopbuffer
+
+\typebuffer
+
+This becomes:
+
+\getbuffer
+
+and exports as:
+
+\starttyping[escape=yes]
+<formula>
+  <formulacontent>
+    <m:math display="block">
+      <m:mrow>
+        <m:mi>/BTEX\it e/ETEX</m:mi>
+        <m:mo>=</m:mo>
+        <m:mi>/BTEX\it m/ETEX</m:mi>
+        <m:msup>
+          <m:mi>/BTEX\it c/ETEX</m:mi>
+          <m:mn>2</m:mn>
+        </m:msup>
+      </m:mrow>
+    </m:math>
+  </formulacontent>
+  <formulacaption>
+    (<formulanumber detail='formula'>1.1</formulanumber>)
+  </formulacaption>
+</formula>
+\stoptyping
+
+The caption can also have a label in front of the number. The best way to deal
+with this still under consideration. I leave it to the reader to wonder how we
+get the caption at the same level as the content while in practice the number is
+part of the formula.
+
+Anyway, the previous pages have demonstrated that with version 0.22 of the
+exporter we can already get a quite acceptable math export. Of course more will
+follow.

+\startchapter[title={Including pages}]
+
+\startsection [title={Introduction}]
+
+It is tempting to add more and more features to the backend code
+of the engine but it is not really needed. Of course there are
+features that can best be supported natively, like including
+images. In order to include \PDF\ images in \LUATEX\ the backend
+uses a library (xpdf or poppler) that can load an page from a file
+and embed that page into the final \PDF, including all relevant
+(indirect) objects needed for rendering. In \LUATEX\ an
+experimental interface to this library is included, tagged as
+\type {epdf}. In this chapter I will spend a few words on my first
+attempt to use this new library.
+
+\stopsection
+
+\startsection [title={The library}]
+
+The interface is rather low level. I got the following example
+from Hartmut (who is responsible for the \LUATEX\ backend code and
+this library).
+
+\starttyping
+local doc = epdf.open("luatexref-t.pdf")
+local cat = doc:getCatalog()
+local pag = cat:getPage(3)
+local box = pag:getMediaBox()
+
+local w = pag:getMediaWidth()
+local h = pag:getMediaHeight()
+local n = cat:getNumPages()
+local m = cat:readMetadata()
+
+print("nofpages: ", n)
+print("metadata: ", m)
+print("pagesize: ", w .. " * " .. h)
+print("mediabox: ", box.x1, box.x2, box.y1, box.y2)
+\stoptyping
+
+As you see, there are accessors for each interesting property
+of the file. Of course such an interface needs to be extended
+when the \PDF\ standard evolves. However, once we have access to
+the so called catalog, we can use regular accessors to the
+dictionaries, arrays and other data structures. So, in fact we
+don't need a full interface and can draw the line somewhere.
+
+There are a couple of things that you normally do not want to
+deal with. A \PDF\ file is in fact just a collection of objects
+that form a tree and each object can be reached by an index using
+a table that links the index to a position in the file. You don't
+want to be bothered with that kind of housekeeping indeed. Some data
+in the file, like page objects and annotations are organized in a
+tree form that one does not want to access in that form, so again
+we have something that benefits from an interface. But the
+majority of the objects are simple dictionaries and arrays.
+Streams (these hold the document content, image data, etc.) are
+normally not of much interest, but the library provides an
+interface as you can bet on needing it someday. The library also
+provides ways to extend the loaded \PDF\ file. I will not discuss
+that here.
+
+Because in \CONTEXT\ we already have the \type {lpdf} library for
+creating \PDF\ structures, it makes sense to define a similar
+interface for accessing \PDF. For that I wrote a wrapper that will
+be extended in due time (read: depending on needs). The previous
+code now looks as follows:
+
+\starttyping
+local doc = epdf.open("luatexref-t.pdf")
+local cat = doc.Catalog
+local pag = cat.Pages[3]
+local box = pag.MediaBox
+
+local llx, lly, urx, ury = box[1], box[2] box[3], box[4]
+
+local w = urx - llx -- or: box.width
+local h = ury - lly -- or: box.height
+local n = cat.Pages.size
+local m = cat.Metadata.stream
+
+print("nofpages: ", n)
+print("metadata: ", m)
+print("pagesize: ", w .. " * " .. h)
+print("mediabox: ", llx, lly, urx, ury)
+\stoptyping
+
+If we write code this way we are less dependent on the exact \API,
+especially because the \type {epdf} library uses methods to access
+the data and we cannot easily overload method names in there. When
+you look at the \type {box}, you will see that the natural way to
+access entries is using a number. As a bonus we also provide the
+\type {width} and \type {height} entries.
+
+\stopsection
+
+\startsection [title={Merging links}]
+
+It has always been on my agenda to add the possibility to carry
+the (link) annotations with an included page from a document. This
+is not that much needed in a regular document, but it can be handy
+when you use \CONTEXT\ to assemble documents. In any case, such a
+merge has to happen in such a way that it does not interfere with
+other links in the parent document. Supporting this in the engine
+is no option as each macro package follows its own approach to
+referencing and interactivity. Also, demands might differ and one
+would end up with a lot of (error prone) configurability. Of course
+we want scaled pages to behave well too.
+
+Implementing the merge took about a day and most of that time was
+spent on experimenting with the \type {epdf} library and making
+the first version of the wrapper. I definitely had expected to
+waste more time on it. So, this is yet another example of
+extensions that are quite doable in the \LUA|-|\TEX\ mix. Of
+course it helps that the \CONTEXT\ graphic inclusion code provides
+enough information to integrate such a feature. The merge is
+controlled by the interaction key, as shown here:
+
+\starttyping
+\externalfigure[somefile.pdf][page=1,scale=700,interaction=yes]
+\externalfigure[somefile.pdf][page=2,scale=600,interaction=yes]
+\externalfigure[somefile.pdf][page=3,scale=500,interaction=yes]
+\stoptyping
+
+You can finetune the merge by providing a list of options to the
+interaction key but that's still somewhat experimental. As a start
+the following links are supported.
+
+\startitemize[packed]
+\startitem internal references by name (often structure related) \stopitem
+\startitem internal references by page (e.g.\ table of contents) \stopitem
+\startitem external references by file (optionally by name and page) \stopitem
+\startitem references to uri's (normally used for webpages) \stopitem
+\stopitemize
+
+When users like this functionality (or when I really need it
+myself) more types of annotations can be added although support
+for \JAVASCRIPT\ and widgets doesn't make much sense. On the other
+hand, support for destinations is currently somewhat simplified
+but at some point we will support the relevant zoom options.
+
+The implementation is not that complex:
+
+\startitemize[packed]
+\startitem check if the included page has annotations \stopitem
+\startitem loop over the list of annotations and determine if
+           an annotation is supported (currently links) \stopitem
+\startitem analyze the annotation and overlay a button using the
+           destination that belongs to the annotation \stopitem
+\stopitemize
+
+Now, the reason why we can keep the implementation so simple is that
+we just map onto existing \CONTEXT\ functionality. And, as we have
+a rather integrated support for interactive actions, only a few
+basic commands are involved. Although we could do that all in
+\LUA, we delegate this to \TEX. We create a layer which we put on top
+of the image. Links are put onto this layer using the equivalent of:
+
+\starttyping
+\setlayer
+  [epdflinks]
+  [x=...,y=...,preset=leftbottom]
+  {\button
+     [width=...,height=...,offset=overlay,frame=off]
+     {}% no content
+     [...]}}
+\stoptyping
+
+The \type {\button} command is one of those interaction related
+commands that accepts any action related directive. In this first
+implementation we see the following destinations show up:
+
+\starttyping
+somelocation
+url(http://www.pragma-ade.com)
+file(somefile)
+somefile::somelocation
+somefile::page(10)
+\stoptyping
+
+References to pages become named destinations and are later
+resolved to page destinations again, depending on the
+configuration of the main document. The links within an included
+file get their own namespace so (hopefully) they will not clash
+with other links.
+
+We could use lower level code which is faster but we're not
+talking of time critical code here. At some point I might optimize
+the code a bit but for the moment this variant gives us some
+tracing options for free. Now, the nice thing about using this
+approach is that the already existing cross referencing mechanisms
+deal with the details. Each included page gets a unique reference
+so references to not included pages are ignored simply because
+they cannot be resolved. We can even consider overloading certain
+types of links or ignoring named destinations that match a
+specific pattern. Nothing is hard coded in the engine so we have
+complete freedom of doing that.
+
+\stopsection
+
+\startsection [title={Merging layers}]
+
+When including graphics from other applications it might be that
+they have their content organized in layers (that then can be
+turned on or off). So it will be no surprise that on the agenda is
+merging layer information: first a straightforward inclusion of
+optional content dictionaries, but it might make sense to parse
+the content stream and replace references to layers by those that
+are relevant in the main document. Especially when graphics come
+from different sources and layer names are inconsistent some
+manipulation might be needed so maybe we need more detailed
+control. Implementing this is is no big deal and mostly a matter
+of figuring out a clean and simple user interface.

+story.
+
+\stopsection
+
+\startsection [title={Defining macros}]
+
+When you define macros in \TEX, you use the \type {#} to indicate variables. So,
+you code can end up with the following:
+
+\startbuffer
+\def\MyTest#1#2#3#4%
+  {\dontleavehmode
+   \dostepwiserecurse{#1}{#2}{#3}
+     {\ifnum\recurselevel>#1 \space,\fi
+      \recurselevel: #4\space}%
+   .\par}
+\stopbuffer
+
+\typebuffer
+
+This macro is called with 4 arguments:
+
+\starttyping
+\MyTest{3}{8}{1}{Hi}
+\stoptyping
+
+However, using numbers as variable identifiers might not have your preference. It
+makes perfect sense if you keep in mind that \TEX\ supports delimited arguments
+using arbitrary characters. But in practice, and especially in \CONTEXT\ we use
+only a few well defined variants. \ This is why you can also imagine:
+
+\startbuffer
+\def\MyTest#first#last#step#text%
+  {\dontleavehmode
+   \dostepwiserecurse{#first}{#last}{#step}
+     {\ifnum\recurselevel>#first \space,\fi
+      \recurselevel: #text}%
+   .\par}
+\stopbuffer
+
+\typebuffer
+
+In order for this to work, you need to give your file the suffix \type {mkvi} or
+you need to put a directive on the first line:
+
+\starttyping
+% macros=mkvi
+\stoptyping
+
+You can of course use delimited arguments as well, given that
+the delimiters are not letters.
+
+\startbuffer
+\def\TestOne[#1]%
+  {this is: #1}
+
+\def\TestTwo#some%
+  {this is: #some}
+
+\def\TestThree[#whatever][#more]%
+  {this is: #more and #whatever}
+
+\def\TestFour[#one]#two%
+  {\def\TestFive[#alpha][#one]%
+     {#one, #two, #alpha}}
+\stopbuffer
+
+\typebuffer \mkvibuffer
+
+You can also use the following variant which is already present for a while but
+not that much advertised. This method ignores all spaces in definitions so if you
+need one, you have to use \type {\space}.
+
+\startbuffer
+\starttexdefinition TestSix #oeps
+
+  here: #oeps
+
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer \mkvibuffer
+
+These commands work as expected:
+
+\startbuffer
+\startlines
+  \TestOne  [one]
+  \TestTwo  {one}
+  \TestThree[one][two]
+  \TestFour [one]{two}
+  \TestFive [one][two]
+  \TestSix  {one}
+\stoplines
+\stopbuffer
+
+\typebuffer
+
+% We need to obey catcode changes (we can use \getbuffer
+% instead).
+
+\getbuffer
+
+You can use buffers to collect definitions. In that case you can force
+preprocessing of the buffer with \type {\mkvibuffer[name]}.
+
+\stopsection
+
+\startsection[title={Implementation}]
+
+This functionality is not hard codes in the \LUATEX\ engine as this is not needed
+at all. We just preprocess the file before it gets loaded and this is something
+that is relatively easy to implement. Already early in the development of
+\LUATEX\ we have decided that instead of hard coding solutions, opening up makes
+more sense.
+
+One of the first mechanisms that were opened up was file IO. This means that when
+a file is opened, you can decide to intercept lines and process them before
+passing them to the traditional built in input parser. The user can be completely
+unaware of this. In fact, as \LUATEX\ only accepts \UTF-8 preprocessing will
+likely happen already when other input encodings are used.
+
+The following helper functions are available:
+
+\starttyping
+local result = resolvers.macros.preprocessed(str)
+\stoptyping
+
+This function returns a string with all named parameters
+replaced.
+
+\starttyping
+resolvers.macros.convertfile(oldname,newname)
+\stoptyping
+
+This function converts a file into a new one.
+
+\starttyping
+local result = resolvers.macros.processmkvi(str,filename)
+\stoptyping
+
+This function converts the string but only if the suffix of the filename is \type
+{mkvi} or when the first line of the string is a comment line containing \type
+{macros=mkvi}. Otherwise the original string is returned. The filename is
+optional.
+
+\stopsection
+
+\startsection[title=A few details]
+
+Imagine that you want to do this:
+
+\starttyping
+\def\test#1{before#1after}
+\stoptyping
+
+When we use names this could look like:
+
+\starttyping
+\def\test#inbetween{before#inbetweenafter}
+\stoptyping
+
+and that is not going to work out well. We could be more liberal with spaces,
+like
+
+\starttyping
+\def\test #inbetween {before #inbetween after}
+\stoptyping
+
+but then getting spaces in the output before or after variables would get more
+complex. However, there is a way out:
+
+\starttyping
+\def\test#inbetween{before#{inbetween}after}
+\stoptyping
+
+As the sequence \type +#{+ has a rather low probablility of showing up in a \TEX\
+source file, this kind of escaping is part of the game. So, all the following
+cases are valid:
+
+\starttyping
+\def\test#oeps{... #oeps ...}
+\def\test#oeps{... #{oeps} ...}
+\def\test#{main:oeps}{... #{main:oeps} ...}
+\def\test#{oeps:1}{... #{oeps:1} ...}
+\def\test#{oeps}{... #oeps ...}
+\stoptyping
+
+When you use the braced variant, all characters except braces are acceptable as
+name, optherwise only lowercase and uppercase characters are permitted.
+
+Normally \TEX\ uses a couple of special tokens like \type {^} and \type {_}. In a
+macro definition file you can avoid these by using primitives:
+
+\starttabulate[|cT|lT|]
+\NC \letterampersand           \NC \tex{aligntab}          \NC \NR
+\NC \letterhash                \NC \tex{alignmark}         \NC \NR
+\NC \letterhat                 \NC \tex{Usuperscript}      \NC \NR
+\NC \letterunderscore          \NC \tex{Usubscript}        \NC \NR
+\NC \letterdollar              \NC \tex{Ustartmath}        \NC \NR
+\NC \letterdollar              \NC \tex{Ustopmath}         \NC \NR
+\NC \letterdollar\letterdollar \NC \tex{Ustartdisplaymath} \NC \NR
+\NC \letterdollar\letterdollar \NC \tex{Ustopdisplaymath}  \NC \NR
+\stoptabulate
+
+Especially the \type {aligntab} is worth noticing: using that one directly in a
+macro definition can result in unwanted replacements, depending whether a match
+can be found. In practice the following works out well
+
+\starttyping
+\def\test#oeps{test:#oeps \halign{##\cr #oeps\cr}}
+\stoptyping
+
+You can use \UTF-8\ characters as well. For practical reasons this is only
+possible with the braced variant.
+
+\starttyping
+\def\blä#{blá}{blà:#{blá}}
+\stoptyping
+
+There will probably be more features in future versions but each of them needs
+careful consideration in order to prevent interferences.
+
+\stopsection
+
+\startsection[title=Utilities]
+
+There is currently one utility (or in fact an option to an existing utility):
+
+\starttyping
+mtxrun --script interface --preprocess whatever.mkvi
+\stoptyping
+
+This will convert the given file(s) to new ones, with the default suffix
+\type{tex}. Existing files will not be overwritten unless \type {---force} is
+given. You can also force another suffix:
+
+\starttyping
+mtxrun --script interface --preprocess whatever.mkvi --suffix=mkiv
+\stoptyping
+
+A rather plain module \type {luatex-preprocessor.lua} is provided for other
+usage. That variant provides a somewhat simplified version.
+
+Given that you have a \type {luatex-plain} format you can run:
+
+\starttyping
+luatex --fmt=luatex-plain luatex-preprocessor-test.tex
+\stoptyping
+
+Such a plain format can be made with:
+
+\starttyping
+luatex --ini luatex-plain
+\stoptyping
+
+You probably need to move the format to a proper location in your \TEX\ tree.

+
+Occasionally we do some timing on new functionality in either
+\LUATEX\ or \MKIV, so here's another wrapup.
+
+\stopsection
+
+\startsection [title={Font loading}]
+
+In \CONTEXT\ we cache font data in a certain way. Loading a font from the cache
+takes hardly any time. However, preparation takes more time as well memory as we
+need to go from the fontforge ordering to one we can use. In \MKIV\ we have
+several font tables:
+
+\startitemize[packed]
+\startitem
+    The original fontforge table: this one is only loaded once and converted to
+    another representation that is cached.
+\stopitem
+\startitem
+    The cached font representation that is the basis for further manipulations.
+\stopitem
+\startitem
+    In base mode this table is converted to a (optionally cached) scaled \TFM\
+    table that is passed to \TEX.
+\stopitem
+\startitem
+    In node mode a limited scaled version is passed to \TEX. As with base mode,
+    this table is kept in memory so that we can access the data.
+\stopitem
+\startitem
+    When processing features in node mode additional (shared) subtables are
+    created that extend the memorized catched table.
+\stopitem
+\stopitemize
+
+This model is already quite old and dates from the beginning of \MKIV. Future
+versions might use different derived tables but for the moment we need all this
+data if only because it helps us with the development.
+
+The regular method to construct a font suitable for \TEX, either or not using
+base mode or node mode in \MKIV, is to load the font as table using \type
+{to_table}, a \type {fontloader} method. This means that all information is
+available (and can be manipulated). In \MKIV\ this table is converted to another
+one and in the process new entries are added and existing ones are freed. Quite
+some garbage collection and table resizing takes place in the process. In the
+cached instance we share identical tables so there we can gain a lot of memory
+and avoid garbage collection.
+
+The difference in usage is as follows:
+
+\starttyping
+do
+  local f = fontloader.open("somefont.otf") -- allocates font object
+  local t = fontloader.to_table(f)          -- allocates table
+  fontloader.close(f)                       -- frees font object
+  for index, glyph in pairs(t) do
+    local width = glyph.width               -- accesses table value
+  end
+end                                         -- frees table
+\stoptyping
+
+Here \type {t} is a complete \LUA\ table and it can get quite large: script fonts
+like Zapfino (for latin) or Husayni (for arabic) have lots of alternate shapes
+and much features related information, fonts meant for \CJK\ usage have tens of
+thousands of glyphs, and math fonts like Cambria have many glyphs and math
+specific information.
+
+\starttyping
+do
+  local f = fontloader.open("somefont.otf") -- allocates font object
+  for index=0, t.glyphmax-1 do
+    local glyph = f.glyphs[index]           -- assigns user data object
+    if glyph then
+      local width = glyph.width             -- calls virtual table value
+    end
+  end
+  fontloader.close(f)                       -- frees font object
+end
+\stoptyping
+
+In this case there is no big table, and \type {glyph} is a so called userdata
+object. Its entries are created when asked for. So, where in the first example
+the \type {width} of a glyph is a number, in the second case it is a function
+disguised as virtual key that will return a number. In the first case you can
+change the width, in the second case you can't.
+
+This means that if you want to keep the data around you need to copy it into
+another table but you can do that stepwise and selectively. Alternatively you can
+keep the font object in memory. As some glyphs can have much data you can imagine
+that when you only need to access the width, the userdata method is more
+efficient. On the other hand, if you need access to all information, the first
+method is more interesting as less overhead is involved.
+
+In the userdata variant only the parent table and its glyph subtable are
+virtualized, as are entries in an optional subfonts table. So, if you ask for the
+kerns table of a glyph you will get a real table as it makes no sense to
+virtualize it. A way in between would have been to request tabls per glyph but as
+we will see there is no real benefit in that while it would further complicate
+the code.
+
+When in \LUATEX\ 0.63 the loaded font object became partially virtual it was time
+to revision the loading code to see if we could benefit from this.
+
+In the following tables we distinguish three cases: the original but adapted
+loading code \footnote {For practical reasons we share as much odd as possible
+between the methods so some reorganization was needed.}, already a few years old,
+the new sparse loading code, using the userdata approach and no longer a raw
+table, and a mixed approach where we still use the raw table but instead of
+manipulating that one, construct a new one from it. It must be noticed that in
+the process of integrating the new method the traditional method suffered.
+
+First we tested Oriental \TEX's Husayni font. This one has lots of features, many
+of lookups, and quite some glyphs. Keep in mind that the times concern the
+preparation and not the reload from the cache, which is more of less neglectable.
+The memory consumption is a snapshot of the current run just after the font has
+been loaded. Peak memory is what bothers most users. Later we will explain what
+the values between parenthesis refer to.

+\stoptabulate
+
+So, here the new method is not offering any advantages. As this is a font we use
+quite a lot during development, any loading variant will do the job with similar
+efficiency.
+
+Next comes Cambria, a font that carries lots of glyphs and has extensive support
+for math. In order to provide a complete bodyfont setup some six instances are
+loaded. Interesting is that the original module needs 3.9 seconds instead if 6.4
+which is probably due to a different ordering of code which might influence the
+garbage collector and it looks like in the reorganized code the garbage collector
+kicks in a few times during the font loading. Already long ago we found out that
+this is also somewhat platform dependent.

+\stoptabulate
+
+Here the sparse method reports less memory usage. There is no other gain as there
+is a lot of access to glyph data due to the fact that this font is rather
+advanced. More virtualization would probably work against us here.
+
+Being a \CJK\ font, the somewhat feature|-|dumb but large AdobeSongStd-Light has
+lots of glyphs. In previous tables we already saw values between parenthesis:
+these are values measured with implicit calls to the garbage collector before
+writing the font to the cache. For this font much more memory is used but garbage
+collection has a positive impact on memory consumption but drastic consequences
+for runtime. Eventually it's the cached timing that matters and that is a
+constant factor but even then it can disturb users if a first run after an update
+takes so much time.

+
+Peak memory is quite high for the sparse method which is due to the fact that we
+have only glyphs (but many) so we have lots of access and small tables being
+created and collected. I suspect that in a regular run the loading time is much
+lower for the sparse case because this is just too much of a difference.
+
+The last test loaded 40 variants of Latin Modern. Each font has reasonable number
+of glyphs (covering the latin script takes some 400--600 glyphs), the normal
+amount of kerning, but hardly any features. Reloading these 40 fonts takes about
+a second.

+
+The old method wins in runtime and this makes it hard to decide which strategy to
+follow. Again the numbers between parenthesis show what happens when we do an
+extra garbage collection sweep after packaging the font instance. A few more
+sweeps in other spots will bring down memory a few megabytes but at the cost of
+quite some runtime. The original module that uses the table approach is 3~seconds
+faster that the current one. As the code is essentially the same but organized
+differently again we suspect the garbage collector to be the culprit.
+
+So when we came this far, Taco and I did some further tests and on his machine
+Taco ran a profiler on some of the tests. He posted the following conclusion to
+the \LUATEX\ mailing list:
+
+\startnarrower
+It seems that the userdata access is useful if {\em but only if} you are very low
+on memory. In other cases, it just adds extra objects to be garbage collected,
+which makes the collector slower. That is on top of extra time spent on the
+actual calls, and even worse: those extra gc objects tend to be scattered around
+in memory, resulting in extra minor page faults (cpu cache misses) and all that
+has a noticeable effect on run speed: the metatable based access is 20--30\%
+slower than the old massive \type {to_table}.
+
+Therefore, there seems little point in expanding the metadata functionality any
+further. What is there will stay, but adding more metadata objects appears to be
+a waste of time on all sides.
+\stopnarrower
+
+This leaves us with a question: should we replace the old module by the
+experimental one? It makes sense to do this as in practice users will not be
+harmed much. Fonts are cached and loading a cached font is not influenced. The
+new module leaves the choice to the user. He or she can decide to limit memory
+usage (for cache building) by using directives:
+
+\starttyping
+\enabledirectives[fonts.otf.loader.method=table]
+\enabledirectives[fonts.otf.loader.method=mixed]
+\enabledirectives[fonts.otf.loader.method=sparse]
+
+\enabledirectives[fonts.otf.loader.cleanup]
+\enabledirectives[fonts.otf.loader.cleanup=1]
+\enabledirectives[fonts.otf.loader.cleanup=2]
+\enabledirectives[fonts.otf.loader.cleanup=3]
+\stoptyping
+
+The cleanup has three levels and each level adds a garbage collection sweep (in a
+different spot). Of course three sweeps per font that is prepared for caching has
+quite some impact on performance. If your computer has enough memory it makes no
+sense to use any of these directives. For the record: these directives are not
+available in the generic (plain \TEX) variant, at least not in the short term. As
+Taco mentions, cache misses can have drastic consequences and we've ran into that
+years ago already when support for \OPENTYPE\ math was added to \LUATEX: out of a
+sudden and without no reason passing a font table to \TEX\ became twice as slow
+on my machine. This is comparable with the new, reorganized table loader being
+slower than the old one. Eventually I'll get back that time, which is unlikely to
+happen with the unserdata variant where there is no way to bring down the number
+of function calls and intermediate table creation.
+
+The previously shown values that concern all fonts including creating, caching,
+reloading, creating a scaled instance and passing the data to \TEX. In that
+process quite some garbage collection can happen and that obscures the real
+values. However, in \MKIV\ we report the conversion time when a font gets cached
+so that the user at least sees something happening. These timings are on a per
+font base. Watch the following values:
+

+\LL
+\stoptabulate
+
+In the case of Cambria several fonts are loaded including subfonts from
+\TRUETYPE\ containers. This shows that the table variant is definitely faster. It
+might be that later this is compensated by additional garbage collection but that
+would even worsen the sparse case were more extensive userdata be used. These
+values more reflect what Taco measured in the profiler. Improvements to the
+garbage collector are more likely to happen than a drastic speed up in function
+calls so the table variant is still a safe bet.
+
+There are a few places where the renewed code can be optimized so these numbers
+are not definitive. Also, the loader code was not the only code adapted. As we
+cannot manipulate the main table in the userdata variant, the code related to
+patches and extra features like \type {tlig}, \type {trep} and \type {anum} had
+to be rewritten as well: more code and a bit more close to the final table
+format.

+The timings in the previous table concern runs of a few documents where the \type

+cache so all fonts are preprocessed. The memory consumption is the peak load as
+reported by the task manager and we need to keep in mind that \LUA\ allocates
+more than it needs. Keep in mind that these values are so high because fonts are
+created. A regular run takes less memory. Interesting is that for \type {mk} the
+original implementation performs better but the difference is about a second
+which again indicates that the garbage collector is a major factor. Timing only
+the total runtime gives:

+Here we used the system timer while in previous tables we used the values as

+
+The timings above are taken on my laptop running Windows 7 and this is not that
+good a platform for precise timings. Tacos measurements were done with
+specialized tools and should be trusted more. It looks indeed that the current
+level of userdata support is about the best compromise one can get.
+
+{\em In the process I also experimented with virtualizing the final \TFM\ table,
+thereby simulating the upcoming virtualization of that table in \LUATEX.
+Interesting is that for (for instance) \type {mk.pdf} memory consumption went
+down with 20\% but that document is non|-|typical and loades many fonts,
+including vitual punk fonts. However, as access to that tables happens
+infrequently virtualization makes muich sense there, again only at the toplevel
+of the characters subtable.}
+
+\stopsection
+
+\startsection [title={Hyperlinks}]
+
+At \PRAGMA\ we have a long tradition of creating highly interactive documents. I
+still remember the days that processing a 20.000 page document with numerous
+menus and buttons on each page took a while to get finished, especially if each
+page has a \METAPOST\ graphic as well.
+
+On a regular computer a document with so many links is no real problem. After
+all, the \PDF\ format is designed in such a way that only the partial content has
+to be loaded. However, half a million hyperlinks do demand some memory.
+
+Recently I had to make a document that targets at one of these tablets and it is
+no secret that tablets (and e-readers) don't have that much memory. As in
+\CONTEXT\ \MKIV\ we have a bit more control over the backend, it will be no
+surprise that we are able to deal with such issues more comfortable than in
+\MKII.
+
+That specific document (part of a series) contained 1100 pages and each page has
+a navigation menu as well as an alphabetic index into the register. There is a
+table of contents refering to about 200 chapters and these are backlinked to the
+table of contents. There are some also 200 images and tables that end up
+elsewhere and again are crosslinked. Of course there is the usual bunch of inline
+hyperlinks. So, in total this document has some 32.000 hyperlinks. The input is a
+3.03 MB \XML\ file.

+
+So, by aggressively sharing hyperlinks and turning all internal named
+destinations into page destinations we bring down the size noticeably and even
+have a faster run. It is for this reason that aggressive sharing is enabled by
+default. I you don't want it, you can disable it with:
+
+\starttyping
+\disabledirectives[refences.sharelinks]
+\stoptyping
+
+Currently we use names for internal (automatically generated) links. We can force
+page links for them but still use names for explicit references so that we can
+reach them from external documents; this is called mixed mode. When no references
+from outside are needed, you can force pagelinks. At some point mixed mode can
+become the default.
+
+\starttyping
+\enabledirectives[references.linkmethod=page]
+\stoptyping
+
+With values: \type {page}, \type {mixed}, \type {names} and \type {yes} being
+equivalent to \type {page}. The \MKII\ way of setting this is still supported:
+
+\starttyping
+\setupinteraction[page=yes]
+\stoptyping
+
+We could probably gain quite some more bytes by turning all repetitive elements
+into shared graphical objects but it only makes sense to spend time on that when
+a project really needs it (and pays for it). There is upto one megabyte of
+(compressed) data related to menus and other screen real estate that qualifies
+for this but it might not be worth the trouble.
+
+The reason for trying to minimize the amount of hyperlink related metadata (in
+\PDF\ terminology annotations) is that on tablets with not that much memory (and
+no virtual memory) we don't want to keep too much of that (redundant) data in
+memory. And indeed, the optimized document feels more responsive than the dirty
+version, but that could as well be related to the viewing applications.
+
+\stopsection
+
+\startsection[title=Constants]
+
+Not every optimization saves memory of runtime. They are more optimizations due
+to changes in circumstances. When \TEX\ had only 256 registers one had to find
+ways to get round this. For instance counters are quite handy and you could
+quickly run out of them. In \CONTEXT\ there are two ways to deal with this.
+Instead of a real count register you can use a macro:
+
+\starttyping
+\newcounter \somecounter
+\increment  \somecounter
+\decrement (\somecounter,4)
+\stoptyping
+
+In \MKIV\ many such pseudo counters have been replaced by real ones which is
+somewhat faster in usage.
+
+Often one needs a constant and a convenient way to define such a frozen counter
+is:
+
+\starttyping
+\chardef \myconstant 10
+\ifnum \myvariable = \myconstant ....
+\ifcase \myconstant ...
+\stoptyping
+
+This is both efficient and fast and works out well because \TEX\ treats them as
+numbers in comparisons. However, it is somewhat clumsy, as constants have nothing
+to do with characters. This is why all such definitions have been replaced by:
+
+\starttyping
+\newconstant \myconstant 10
+\setconstant \myconstant 12
+\ifnum \myvariable = \myconstant ....
+\ifcase \myconstant ...
+\stoptyping
+
+We use count registers which means that when you set a constant, you can just
+assign the new value directly or use the \type {\setcounter} macro.
+
+We already had an alternative for conditionals:
+
+\starttyping
+\newconditional \mycondition
+\settrue \mycondition
+\setfalse \mycondition
+\ifconditional \mycondition
+\stoptyping
+
+These will also be adapted to counts but first we need a new primitive.
+
+The advantage of these changes is that at the \LUA\ end we can consult as well as
+change these values. This means that in the end much more code will be adapted.
+Especially changing the constants resulted in quite some cosmetic changes in the
+core code.
+
+\stopsection
+
+\startsection[title=Definitions]
+
+Another recent optimization was possible when at the \LUA end settings lccodes
+cum suis and some math definitions became possible. As all these initializations
+take place at the \LUA\ end till then we were just writing \TEX\ code back to
+\TEX, but now we stay at the \LUA end. This not only looks nicer, but also
+results in a slightly less memory usage during format generation (a few percent).
+Making a format also takes a few tenths of a second less (again a few percent).
+The reason why less memory is needed is that instead of writing tens of thousands
+\type {\lccode} related commands to \TEX\ we now set the value directly. As
+writes to \TEX\ are collected, quite an amount of tokens get cached.
+
+All such small improvements makes that \CONTEXT\ \MKIV\ runs smoother with each
+advance of \LUATEX. We do have a wishlist for further improvements but so far we
+managed to improve stepwise instead of putting too much pressure on \LUATEX\

+\startsection [title={Introduction}]
+
+You enter the den of the Lion when you start messing around with the parbuilder.
+Actually, as \TEX\ does a pretty good job on breaking paragraphs into lines I
+never really looked into the code that does it all. However, the Oriental \TEX\
+project kind of forced it upon me. In the chapter about font goodies an optimizer
+is described that works per line. This method is somewhat similar to expansion
+level~one support (hz) in the sense that it acts independent of the par builder:
+the split off (best) lines are postprocessed. Where expansion involves horizontal
+scaling, the goodies approach does with (Arabic) words what the original HZ
+approach does with glyphs.
+
+It would be quite some challenge (at least for me) to come up with solutions that
+look at the whole paragraph and as the per-line approach works quite well, there
+is no real need for an alternative. However, in September 2008, when we were
+exploring solutions for Arabic par building, Taco converted the parbuilder into
+\LUA\ code and stripped away all code related to hyphenation, protrusion,
+expansion, last line fitting, and some more. As we had enough on our plate at
+that time, we never came to really testing it. There was even less reason to
+explore this route because in the Oriental \TEX\ project we decided to follow the
+\quotation {use advanced \OPENTYPE\ features} route which in turn lead to the
+\quote {replace words in lines by narrower of wider variants} approach.
+
+However, as the code was laying around and as we want to explore further I
+decided to pick up the parbuilder thread. In this chapter some experiences will
+be discussed. The following story is as much Taco's as mine.
+
+\stopsection
+
+\startsection [title={Cleaning up}]
+
+In retrospect, we should not have been too surprised that the first approximation
+was broken in many places, and for good reason. The first version of the code was
+a conversion of the \CCODE\ code that in turn was a conversion from the original
+interwoven \PASCAL\ code. That first conversion still looked quite \CCODE||ish
+and carried interesting bit and pieces of \CCODE||macros, \CCODE||like pointer
+tests, interesting magic constants and more.
+
+When I took the code and \LUA-fied it nearly every line was changed and it took
+Taco and me a bit of reverse engineering to sort out all problems (thank you
+Skype). Why was it not an easy task? There are good reasons for this.
+
+\startitemize
+
+\startitem The parbuilder (and related hpacking) code is derived from traditional
+\TEX\ and has bits of \PDFTEX, \ALEPH\ (\OMEGA), and of course \LUATEX. \stopitem
+
+\startitem The advocated approach to extending \TEX\ has been to use change files
+which means that a coder does not see the whole picture. \stopitem
+
+\startitem Originally the code is programmed in the literate way which means that
+the resulting functions are build stepwise. However, the final functions can (and
+have) become quite large. Because \LUATEX\ uses the woven (merged) code indeed we
+have large functions. Of course this relates to the fact that succesive \TEX\
+engines have added functionality. Eventually the source will be webbed again, but
+in a more sequential way. \stopitem
+
+\startitem This is normally no big deal, but the \ALEPH\ (\OMEGA) code has added
+a level of complexity due to directional processing and additional begin and end
+related boxes. \stopitem
+
+\startitem Also the \ETEX\ extension that deals with last line fitting is
+interwoven and uses goto's for the control flow. Fortunately the extensions are
+driven by parameters which make the related code sections easy to recognize.
+\stopitem
+
+\startitem The \PDFTEX\ protrusion extension adds code to glyph handling and
+discretionary handling. The expansion feature does that too and in addition also
+messes around with kerns. Extra parameters are introduced (and adapted) that
+influence the decisions for breaking lines. There is also code originating in
+\PDFTEX\ which deals with poor mans grid snapping although that is quite isolated
+and not interwoven. \stopitem
+
+\startitem Because it uses a slightly different way to deal with hyphenation,
+\LUATEX\ itself also adds some code. \stopitem
+
+\startitem Tracing is sort of interwoven in the code. As it uses goto's to share
+code instead of functions, one needs to keep a good eye on what gets skipped or
+not. \stopitem
+
+\stopitemize
+
+I'm pretty sure that the code that we started with looks quite different from the
+original \TEX\ code if it had been translated into \CCODE. Actually in modern
+\TEX\ compiling involves a translation into \CCODE\ first but the intermediate
+form is not meant for human eyes. As the \LUATEX\ project started from that
+merged code, Taco and Hartmut already spent quite some time on making it more
+readable. Of course the original comments are still there.
+
+Cleaning up such code takes a while. Because both languages are similar but also
+quite different it took some time to get compatible output. Because the \CCODE\
+code uses macros, careful checking was needed. Of course \LUA's table model and
+local variables brought some work as well. And still the code looks a bit
+\CCODE||ish. We could not divert too much from the original model simply because
+it's well documented.
+
+When moving around code redundant tests and orphan code has been removed. Future
+versions (or variants) might as well look much different as I want more hooks,
+clearly split stages, and convert some linked list based mechanism to \LUA\
+tables. On the other hand, as already much code has been written for \CONTEXT\
+\MKIV, making it all reasonable fast was no big deal.
+
+\stopsection
+
+\startsection [title={Expansion}]
+
+The original \CCODE||code related to protrusion and expansion is not that
+efficient as many (redundant) function calls take place in the linebreaker and
+packer. As most work related to fonts is done in the backend, we can simply stick
+to width calculations here. Also, it is no problem at all that we use floating
+point calculations (as \LUA\ has only floats). The final result will look okay as
+the original hpack routine will nicely compensate for rounding errors as it will
+normally distribute the content well enough. We are currently compatible with the
+regular par builder and protrusion code, but expansion gives different results
+(actually not worse).
+
+The \LUA\ hpacker follows a different approach. And let's admit it: most \TEX ies
+won't see the difference anyway. As long as we're cross platform compatible it's
+fine.
+
+It is a well known fact that character expansion slows down the parbuilder. There
+are good reasons for this in the \PDFTEX\ approach. Each glyph and intercharacter
+kern is checked a few times for stretch or shrink using a function call. Also
+each font reference is checked. This is a side effect of the way \PDFTEX\ backend
+works as there each variant has its own font. However, in \LUATEX, we scale
+inline and therefore don't really need the fonts. Even better, we can get rid of
+all that testing and only need to pass the eventual \type {expansion_ratio} so
+that the backend can do the right scaling. We will prototype this in the \LUA\
+version \footnote {For this Hartmuts has adapted the backend code has to honour
+this field in the glyph and kern nodes.} and we feel confident about this
+approach it will be backported into the \CCODE\ code base. So eventually the
+\CCODE\ might become a bit more readable and efficient.
+
+Intercharacter kerning is dealt with in a somewhat strange way. If a kern of
+subtype zero is seen, and if it's neighbours are glyphs from the same font, the
+kern gets replaced by a scaled one looked up in the font's kerning table. In the
+parbuilder no real replacement takes place but as each line ends up in the hpack
+routine (where all work is simply duplicated and done again) it really gets
+replaced there. When discussing the current aproach we decided, that manipulating
+intercharacter kerns while leaving regular spacing untouched, is not really a
+good idea so there will be an extra level of configuration added to \LUATEX:
+\footnote {As I more and more run into books typeset (not by \TEX) with a
+combination of character expansion and additional intercharacter kerning I've
+been seriously thinking of removing support for expansion from \CONTEXT\ \MKIV.
+Not all is progress especially if it can be abused.}

+\NC 2 \NC character and kern expansion as part of the par builder \NC \NR
+\NC 3 \NC only character expansion as part of the par builder (new) \NC \NR
+\stoptabulate
+
+You might wonder what happens when you unbox such a list: the original font
+references have been replaced as were the kerns. However, when repackaged again,
+the kerns are replaced again. In traditional \TEX, indeed rekerning might happen
+when a paragraph is repackaged (as different hyphenation points might be chosen
+and ligature rebuilding etc.\ has taken place) but in \LUATEX\ we have clearly
+separated stages. An interesting side effect of the conversion is that we really
+have to wonder what certain code does and if it's still needed.

+
+% timeit context ...
+
+We had already noticed that the \LUA\ variant was not that slow. So after the
+first cleanup it was time to do some tests. We used our regular \type {tufte.tex}
+test file. This happens to be a worst case example because each broken line ends
+with a comma or hyphen and these will hang into the margin when protruding is
+enabled. So the solution space is rather large (an example will be shown later).
+
+Here are some timings of the March 26, 2010 version. The test is typeset in a box
+so no shipout takes place. We're talking of 1000 typeset paragraphs. The times
+are in seconds an between parentheses the speed relative to the regular
+parbuilder is mentioned.

+For a regular paragraph the \LUA\ variant (currently) is 5~times slower and about
+6~times when we use the \LUA\ hpacker, which is not that bad given that it's
+interpreted code and that each access to a field in a node involves a function
+call. Actually, we can make a dedicated hpacker as some code can be omitted, The
+reason why the protruding is relatively slow is, that we have quite some
+protruding characters in the test text (many commas and potential hyphens) and
+therefore we have quite some lookups and calculations. In the \CCODE\ variant
+much of that is inlined by macros.
+
+Will things get faster? I'm sure that I can boost the protrusion code and
+probably the rest as well but it will always be slower than the built in
+function. This is no problem as we will only use the \LUA\ variant for
+experiments and special purposes. For that reason more \MKIV\ like tracing will
+be added (some is already present) and more hooks will be provided once the
+builder is more compartimized. Also, future versions of \LUATEX\ will pass around
+paragrapgh related parameters differently so that will have impact on the code as
+well.

+\startchapter[title={Optical optimization}]
+
+One of the objectives of the oriental \TEX\ project has always been to play with
+paragraph optimization. The original assumption was that we needed an advanced
+non|-|standard paragraph builder to Arabic done right but in the end we found out
+that a more straightforward approach is to use a sophisticated \OPENTYPE\ font in
+combination with a paragraph postprocessor that uses the advanced font
+capabilities. This solution is somewhat easier to imagine that a complex
+paragraph builder but still involves quite some juggling.
+
+At the June 2012 meeting of the \NTG\ there was a talk about typesetting
+Devanagari and as fonts are always a nice topic (if only because there is
+something to show) it made sense to tell a bit more about optimizing Arabic at
+the same time. In fact, that presentation was already a few years too late
+because a couple of years back, when the oriental \TEX\ project was presented at
+TUG and Dante meetings, the optimizer was already part of the \CONTEXT\ core
+code. The main reason for not advocating is was the simple fact that no font
+other than the (not yet finished) Husayni font provided the relevant feature set.
+
+The lack of advanced fonts does not prevent us from showing what we're dealing
+with. This is because the \CONTEXT\ mechanisms are generic in the sense that they
+can also be used with regular Latin fonts, although it does not make that much
+sense. Of course only \MKIV\ is supported. In this chapter we will stick to
+Latin. A more extensive article is published by Idris Samawi Hamid and myself in
+the proceedings of the combined euro\TEX and \CONTEXT\ conference.
+
+When discussing optical optimization of a paragraph, a few alternatives come to
+mind:
+
+\startitemize
+
+\startitem One can get rid of extensive spaces by adding additional kerns between
+glyphs. This is often used by poor mans typesetting programns (or routines) and
+can be applied to non|-|connecting scripts. It just looks bad. \stopitem
+
+\startitem Glyphs can be widened a few percent and this is an option that
+\LUATEX\ inherits from its predecessor \PDFTEX. Normally this goes unnoticed
+although excessive scaling makes things worse, and yes, one can run into such
+examples. This strategy goes under the name hz|-|optimization (the hz refers to
+Hermann Zaph, who first came with this solution). \stopitem
+
+\startitem A real nice solution is to replace glyphs by narrower or wider
+variants. This is in fact the ideal hz solution but for it to happen one not only
+needs needs fonts with alternative shapes, but also a machinery that can deal
+with them. \stopitem
+
+\startitem An already old variant is the one first used by Gutenberg, who used
+alternative cuts for certain combinations of characters. This is comparable with
+ligatures. However, to make the look and feel optimal, one needs to analyze the
+text and make decisions on what to replace without loosing consistency. \stopitem
+
+\stopitemize
+
+The solution described here does a bit of everything. As it is mostly meant for a
+connective script, the starting point is how a scribe works when filling up a
+line nicely. Depending on how well he or she can see it coming, the writing can
+be adapted to widen or narrow following words. And it happens that in Arabic
+scripts there are quite some ways to squeeze more characters in a small area
+and|/|or expand some to the extreme to fill up the available space. Shapes can be
+wider or narrower, they can be stacked and they can get replaced by ligatures. Of
+course there is some interference with the optional marks on top and below but
+even there we have some freedom. The only condition is that the characters in a
+word stay connected.
+
+So, given enough alternative glyphs, one can imagine that excessive interword
+spacing can be avoided. However, it is non|-|trivial to check all possible
+combinations. Actually, it is not needed either, as esthetic rules put some
+bounds on what can be done. One should more think in terms of alternative
+strategies or solutions and this is the terminology that we will therefore use.
+
+Easiest is to demonstrate this with Latin, if only because it's more intuitive to
+see what happens. This is not the place to discuss all the gory details so you
+have to take some of the configuration options on face value. Once this mechanism
+is stable and used, the options can be described. For now we stick to presenting
+the idea.
+
+Let's assume that you know what font features are. The idea is to work with
+combinations of such features and figure out what combination suits best. In
+order not to clutter a document style, these sets are defined in so called goodie
+files. Here is an except of \type {demo.lfg}:
+
+\starttyping
+return {
+  name = "demo",
+  version = "1.01",
+  comment = "An example of goodies.",
+  author = "Hans Hagen",
+  featuresets = {
+    simple = {
+      mode   = "node",
+      script = "latn"
+    },
+    default = {
+      mode   = "node",
+      script = "latn",
+      kern   = "yes",
+    },
+    ligatures = {
+      mode   = "node",
+      script = "latn",
+      kern   = "yes",
+      liga   = "yes",
+    },
+    smallcaps = {
+      mode   = "node",
+      script = "latn",
+      kern   = "yes",
+      smcp   = "yes",
+    },
+  },
+  solutions = {
+    experimental = {
+      less = {
+        "ligatures", "simple",
+      },
+      more = {
+        "smallcaps",
+      },
+    },
+  },
+}
+\stoptyping
+
+We see four sets of features here. You can use these sets in a \CONTEXT\
+feature definition, like:
+
+\startbuffer
+\definefontfeature
+  [solution-demo]
+  [goodies=demo,
+   featureset=default]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can use a set as follows:
+
+\startbuffer
+\definefont
+  [SomeTestFont]
+  [texgyrepagellaregular*solution-demo at 10pt]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+So far, there is nothing special and new, but we can go a step further.
+
+\startbuffer[solution-a-b]
+\definefontsolution
+  [solution-a]
+  [goodies=demo,
+   solution=experimental,
+   method={normal,preroll},
+   criterium=1]
+
+\definefontsolution
+  [solution-b]
+  [goodies=demo,
+   solution=experimental,
+   method={normal,preroll,split},
+   criterium=1]
+\stopbuffer
+
+\typebuffer[solution-a-b] \getbuffer[solution-a-b]
+
+Here we have defined two solutions. They refer to the \type {experimental}
+solution in the goodie file \type {demo.lfg}. A solution has a \type {less}
+and a \type {more} entry. The featuresets mentioned there reflect ways to
+make a word narrower of wider. There can be more than one way to do that,
+although it comes at a performance price. Before we see how this works out
+we turn on a tracing option:
+
+\startbuffer
+\enabletrackers
+  [builders.paragraphs.solutions.splitters.colors]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This will color the words in the result according to what has happened. When a
+featureset out of the \type {more} category has been applied, the words turn
+green, when \type {less} is applied, the word becomes yellow. The \type
+{preroll} option in the \type {method} list makes sure that we do a more
+extensive test beforehand.

+strict \footnote {This number reflects the maximum badness and future versions
+might have a different measure with more granularity.}. Keep in mind that we use
+some arbitrary features here. We try removing kerns to get narrower although
+there is nothing that guarantees that kerns are positive. On the other hand,
+using ligatures might help. In order to get wider we use smallcaps. Okay, the
+result will look somewhat strange but so does much typesetting nowadays.
+
+There is one pitfall here. This mechanism is made for a connective script where
+hyphenation is not used. As a result a word here is actually split up when it has
+discretionaries and of course this text fragment has. It goes unnoticed in the
+rendering but is of course far from optimal.

+versions of \CONTEXT\ might get more sophisticated font machinery so then things
+might look better.
+
+We show two more methods:
+
+\startbuffer[solution-c-d]
+\definefontsolution
+  [solution-c]
+  [goodies=demo,
+   solution=experimental,
+   method={reverse,preroll},
+   criterium=1]
+
+\definefontsolution

+  [goodies=demo,
+   solution=experimental,
+   method={random,preroll,split},
+   criterium=1]
+\stopbuffer
+
+\typebuffer[solution-c-d] \getbuffer[solution-c-d]
+
+In \in {figure} [solution-c] we start at the other end of a line. As we sort of
+mimick a scribe, we can be one who plays safe at the start of corrects at the
+end.
+
+\startbuffer[solution-c]
+\SomeTestFont \startfontsolution[solution-c]
+\input zapf \par
+\stopfontsolution
+\stopbuffer
+
+In \in {figure} [solution-d] we add some randomness but to what extent this works
+well depends on how many words we need to retypeset before we get the badness of
+the line within the constraints.

+\startchapter[title={Tagged PDF}]
+
+\startsection [title={Introduction}]
+
+Occasionally users asked me if \CONTEXT\ can produce tagged \PDF\ and the answer
+to that has been: I'll implement it when I need it. However, users tell me that
+publishers more and more demand tagged \PDF\ files, although one might wonder
+what for, except maybe for accessibility. Another reason for not having spent too
+much time on it before is that the specification was not that inviting.
+
+At any rate, when I saw Ross Moore\footnote {He is often exploring the boundaries
+of \PDF, \UNICODE\ and evolving techniques related to math publishing so you'd
+best not miss his presentations when you are around.} presenting tagged math at
+TUG 2010, I decided to look up the spec once more and see if I could get into the
+mood to implement tagging. Before I started it was already clear that there were
+a couple of boundary conditions:
+
+\startitemize[packed]
+\startitem Tagging should not put a burden on the user but users
+           should be able to tag themselves. \stopitem
+\startitem Tagging should not slow down a run too much; this is
+           no big deal as one can postpone tagging till the last
+           run. \stopitem
+\startitem Tagging should in no way interfere with typesetting, so
+           no funny nodes should be injected. \stopitem
+\startitem Tagging should not make the code
+           look worse, neither the document source, nor the low
+           level \CONTEXT\ code. \stopitem
+\stopitemize
+
+And of course implementing it should not take more than a few days' work,
+certainly not in an exceptionally hot summer.
+
+You can \quote {google} for one of Ross's documents (like \type
+{DML_002-2009-1_12.pdf}) to see how a document source looks at his end using a
+special version of \PDFTEX. However, the version on my machine didn't support the
+shown primitives, so I could not see what was happening under the hood.
+Unfortunately it is quite hard to find a properly tagged document so we have only
+the reference manual as starting point. As the \PDFTEX\ approach didn't look that
+pleasing anyway, I just started from scratch.
+
+Tags can help Acrobat Reader when reading out the text aloud. But you cannot
+browse the structure in the no|-|cost version of Acrobat and as not all users
+have the professional version of Acrobat, the fact that a document has structure
+can go unnoticed. Add to that the fact that the overhead in terms of bytes is
+quite large as many more objects are generated, and you will understand why this
+feature is not enabled by default.
+
+\stopsection
+
+\startsection [title={Implementation}]
+
+So, what does tagging boil down to? We can best look at how tagged information is
+shown in Acrobat. \in {Figure} [fig:tagged-list] shows the content tree that has
+been added (automatically) to a document while \in {figure} [fig:tagged-order]
+shows a different view.
+
+\placefigure
+  [page]
+  [fig:tagged-list]
+  {A tag list in Acrobat.}
+  {\externalfigure[tagged-001.png][maxheight=\textheight]}
+
+\placefigure
+  [here]
+  [fig:tagged-order]
+  {Acrobat showing the tag order.}
+  {\externalfigure[tagged-004.png][maxwidth=\textwidth]}
+
+In order to get that far, we have to do the following:
+
+\startitemize[packed]
+\startitem Carry information with (typeset) text. \stopitem
+\startitem Analyse this information when shipping out pages. \stopitem
+\startitem Add a structure tree to the page. \stopitem
+\startitem Add relevant information to the document. \stopitem
+\stopitemize
+
+That first activity is rather independent of the other three and we can use that
+information for other purposes as well, like identifying where we are in the
+document. We carry the information around using attributes. The last three
+activities took a bit of experimenting mostly using the \quotation {Example of
+Logical Structure} from the \PDF\ standard 32000-1:2008.
+
+This resulted in a tagging framework that uses explicit tags, meaning the user is
+responsible for the tagging:
+
+\starttyping
+\setupstructure[state=start,method=none]
+
+\starttext
+
+\startelement[document]
+
+    \startelement[chapter]
+        \startelement[p] \input davis \stopelement \par
+    \stopelement
+
+    \startelement[chapter]
+        \startelement[p] \input zapf \stopelement \par
+        \startelement[whatever]
+            \startelement[p] \input tufte \stopelement \par
+            \startelement[p] \input knuth \stopelement \par
+        \stopelement

+        \startelement[p] \input ward \stopelement \par
+    \stopelement
+
+\stopelement
+
+\stoptext
+\stoptyping
+
+Since this is not much fun, we also provide an automated
+variant. In the previous example we explicitly turned off automated
+tagging by setting \type {method} to \type {none}. By default it has
+the value \type {auto}.
+
+\starttyping
+\setupstructure[state=start] % default is method=auto
+
+\definedescription[whatever]
+
+\starttext
+
+\startfrontmatter
+    \startchapter[title=One]
+        \startparagraph \input tufte \stopparagraph
+        \startitemize
+            \startitem first \stopitem
+            \startitem second \stopitem
+        \stopitemize
+        \startparagraph \input ward \stopparagraph
+        \startwhatever {Herman Zapf} \input zapf \stopwhatever
+    \stopchapter
+
+\stopfrontmatter
+
+\startbodymatter
+    ..................
+\stoptyping
+
+If you use commands like \type {\chapter} you will not get the desired results.
+Of course these can be supported but there is no real reason for it, as in \MKIV\
+we advise using the \type {start}|-|\type {stop} variant.
+
+It will be clear that this kind of automated tagging brings with it a couple of
+extra commands deep down in \CONTEXT\ and there (of course) we use symbolic names
+for tags, so that one can overload the built|-|in mapping.
+
+\starttyping
+\setuptaglabeltext[en][document=text]
+\stoptyping
+
+As with other features inspired by viewer functionality, the implementation of
+tagging is independent of the backend. For instance, we can tag a document and
+access the tagging information at the \TEX\ end. The backend driver code maps
+tags to relevant \PDF\ constructs. First of all, we just map the tags used at the
+\CONTEXT\ end onto themselves. But, as validators expect certain names, we use
+the \PDF\ rolemap feature to map them to (less interesting) names. The next list
+shows the currently used internal names, with the \PDF\ ones between parentheses.
+
+\blank \startalignment[flushleft,nothyphenated]
+\startluacode
+local done = false
+for k, v in table.sortedpairs(structures.tags.properties) do
+    if v.pdf then
+        if done then
+            context(", %s (%s)",k,v.pdf)
+        else
+            context("%s (%s)",k,v.pdf)
+            done = true
+        end
+    end
+end
+context(".")
+\stopluacode \par \stopalignment \blank
+
+So, the internal ones show up in the tag trees as shown in the examples but
+applications might use the rolemap which normally has less detail.
+
+Because we keep track of where we are, we can also use that information for
+making decisions.
+
+\starttyping
+\doifinelementelse{structure:section}            {yes} {no}
+\doifinelementelse{structure:chapter}            {yes} {no}
+\doifinelementelse{division:*-structure:chapter} {yes} {no}
+\doifinelementelse{division:*-structure:*}       {yes} {no}
+\stoptyping
+
+As shown, you can use \type {*} as a wildcard. The elements are separated by
+\type {-}. If you don't know what tags are used, you can always enable the tag
+related tracker:
+
+\starttyping
+\enabletrackers[structure.tags]
+\stoptyping
+
+This tracker reports the identified element chains to the console
+and log.
+
+\stopsection
+
+\startsection[title={Special care}]
+
+Of course there are a few complications. First of all the tagging model sort of
+contradicts the concept of a nicely typeset document where structure and outcome
+are not always related. Most \TEX\ users are aware of the fact that \TEX\ does
+not have space characters and does a great job on kerning and hyphenation. The
+tagging machinery on the other hand uses a rather dumb model of strings separated
+by spaces. \footnote {The search engine on the other hand is rather clever on
+recognizing words.} But we can trick \TEX\ into providing the right information
+to the backend so that words get nicely separated. The non|-|optimized function
+that does this looks as follows:
+
+\starttyping
+function injectspaces(head)
+    local p
+    for n in node.traverse(head) do
+        local id = n.id
+        if id == node.id("glue") then
+            if p and p.id == node.id("glyph") then
+                local g = node.copy(p)
+                local s = node.copy(n.spec)
+                g.char, n.spec = 32, s
+                p.next, g.prev = g, p
+                g.next, n.prev = n, g
+                s.width = s.width - g.width
+            end
+        elseif id == node.id("hlist") or id == node.id("vlist") then
+            injectspaces(n.list,attribute)
+        end
+        p = n
+    end
+end
+\stoptyping
+
+Here we squeeze in a space (given that it is in the font which it normally is
+when you use \CONTEXT) and make a compensation in the glue. Given that your page
+sits in box 255, you can do this just before shipping the page out:
+
+\starttyping
+injectspaces(tex.box[255].list)
+\stoptyping
+
+Then there are the so|-|called suspects: things on the page that are not related
+to structure at all. One is supposed to tag these specially so that the
+built|-|in reading equipment is not confused. So far we could get around them
+simply because they don't get tagged at all and therefore are not seen anyway.
+This might well be enough of a precaution.
+
+Of course we need to deal with mathematics. Fortunately the presentation \MATHML\
+model is rather close to \TEX\ and so we can map onto that. After all we don't
+need to care too much about back|-|mapping here. The currently present code is
+rather experimental and might get extended or thrown out in favour of inline
+\MATHML. \in {Figure} [fig:tagged-math] demonstrates that a first approach does
+not even look that bad. In future versions we might deal with table|-|like math
+constructs, like matrices.
+
+\placefigure
+  [here]
+  [fig:tagged-math]
+  {Experimental math tagging.}
+  {\externalfigure[tagged-005.png][maxwidth=\textwidth]}
+
+This is a typical case where more energy has to be spent on driving the voice of
+Acrobat but I will do that when we find a good reason.
+
+As mentioned, it will take a while before all relevant constructs in \CONTEXT\
+support tagging, but support is already quite complete. Some screen dumps are
+included as examples at the end.
+
+\stopsection
+
+\startsection[title={Conclusion}]
+
+Surprisingly, implementing all this didn't take that much work. Of course
+detailed automated structure support from the complete \CONTEXT\ kernel will take
+some time to get completed, but that will be done on demand and when we run into
+missing bits and pieces. It's still not decided to what extent alternate
+representations and alternate texts will be supported. Experiments with the
+reading|-|aloud machinery are not satisfying yet but maybe it just can't get any
+better. It would be nice if we could get some tags being announced without
+overloading the content, that is: without using ugly hacks.
+
+And of course, code like this is never really finished if only because \PDF\
+evolves. Also, it is yet another nice test case and torture test for \LUATEX\ and
+it helps us to find buglets and oversights.
+
+\stopsection
+
+\startsection [title=Some more examples]
+
+In \CONTEXT\ we have user definable verbatim environments. As with other user
+definable environments we show the specific instance as comment next to the
+structure component. See \in {figure} [fig:tagged-verbatim]. Some examples of
+tables are shown in \in {figure} [fig:tagged-tables]. Future versions will have a
+bit more structure. Tables of contents (see \in {figure} [fig:tagged-contents])
+and registers (see \in {figure} [fig:tagged-register]) are also tagged. (One
+might wonder what the use is of this.) In \in {figure} [fig:tagged-floats] we see
+some examples of floats. External images as well as \METAPOST\ graphics are
+tagged as such. This example also shows an example of a user environment, in this
+case:
+
+\starttyping
+\definestartstop[notabene][style=\bf]
+\stoptyping
+
+In a similar fashion, footnotes (\in {figure} [fig:tagged-footnotes]) end up in
+the structure tree, but in the typeset document they move around (normally
+forward when there is no room).

+
+\startsection[title={Introduction}]
+
+In this chapter I will collect a couple of weird examples.
+
+\stopsection
+
+\startsection[title=Inter-character spacing]
+
+There was a discussion on the \LUATEX\ (dev) list about inter character spacing
+and ligatures. The discussion involved a mechanism inherited from \PDFTEX\ but in
+\CONTEXT\ we don't use that at all. Actually, support for inter character spacing
+was added in an early stage of \MKIV\ development as an alternative for the
+\MKII\ variant, which used parsing at the \TEX\ end. Personally I never use this
+spacing, unless a design in a project demands it.
+
+In the \MKIV\ method we split ligatures when its components are known. This works
+quite well. It's anyway a good idea to disable ligatures, so it's more a
+fallback. Actually we should create components for hard coded characters like
+\ae\ but as no one ever complained I leave that for a later moment.
+
+As we already had the mechanisms in place, support for selective spacing of
+ligatures was a rather trivial extension. If there is ever a real need for it, I
+will provide control via the normal user interface, but for now using a few hooks
+will do. The following code shows an example of an implementation. \footnote {The
+examples have been adapted to the latest \CONTEXT\ where we use \type
+{\getchar(n)} instead of \type {n.char}.}
+
+\startbuffer
+local utfbyte = utf.byte
+local getchar = nodes.nuts.getchar
+
+local keep = {
+    [0x0132] = true, [0x0133] = true, -- IJ ij
+    [0x00C6] = true, [0x00E6] = true, -- AE ae
+    [0x0152] = true, [0x0153] = true, -- OE oe
+}
+
+function typesetters.kerns.keepligature(n)
+    return keep[getchar(n)]
+end
+
+local together = {
+    [utfbyte("c")] = { [utfbyte("k")] = true },
+    [utfbyte("i")] = { [utfbyte("j")] = true },
+    [utfbyte("I")] = { [utfbyte("J")] = true },
+}
+
+function typesetters.kerns.keeptogether(n1,n2)
+    local k = together[getchar(n1)]
+    return k and k[getchar(n2)]
+end
+\stopbuffer
+
+\ctxluabuffer
+
+\typebuffer
+
+The following also works:
+
+\starttyping
+local lpegmatch = lpeg.match
+local fontdata  = fonts.identifiers
+local getchar   = nodes.nuts.getchar
+local getfont   = nodes.nuts.getfont

+
+A more generic solution would be to use the \type {tounicode} information, but it
+would be overkill as we're dealing with a rather predictable set of characters
+that have gotten \UNICODE\ slots assigned. When using basemode most fonts will
+work anyway.
+
+So, is this really worth the effort? Take a look at the following example.
+
+\startbuffer
+\definecharacterkerning [KernMe] [factor=0.25]
+
+\start
+  \setcharacterkerning[KernMe]
+  \definedfont[Serif*default]
+  Ach kijk effe, \ae sop draagt een knickerbocker! \par
+  \definedfont[Serif*smallcaps]
+  Ach kijk effe, \ae sop draagt een knickerbocker! \par
+\stop
+\stopbuffer
+
+\typebuffer
+
+Typeset this (Dutch text) looks like:
+
+\getbuffer
+
+You might wonder why I decided to look into it. Right at the moment when it was
+discussed, I was implementing a style that needed the Calibri font that comes
+with \MSWINDOWS, and I visited the FontShop website to have a look at the font.
+To my surprise it had quite some ligatures, way more than one would expect.
+
+\placefigure
+  {Some of the ligatures in Calibri Regular. Just wonder what
+   intercharacter spacing will do here.}

+There is not much you can do about patterns. It's a craft to make them and so
+they are shipped with the distribution. In order to hyphenate well, \TEX\ looks
+at some character properties. In \CONTEXT\ only the characters used in the
+patterns of a language get tagged as valid in a word.
+
+The following example illustrates that there can be corner cases. In fact, this
+example might render differently depending on the patterns available. First we
+define an extra language, based on French.

+Here we set the \type {factor} parameter which tells the loader that it should

+In traditional \TEX\ ligature building and hyphenation are interwoven with the
+line break mechanism. In \LUATEX\ these phases are isolated. As a consequence we
+deal differently with (a sequence of) explicit hyphens. We already have added
+some control over aspects of the hyphenation and yet another one concerns
+automatic hyphens (e.g.\ \type {-} characters in the input).
+
+When \type {\automatichyphenmode} has a value of 0, a hyphen will be turned into
+an automatic discretionary. The snippets before and after it will not be
+hyphenated. A side effect is that a leading hyphen can lead to a split but one
+will seldom run into that situation. Setting a pre and post character makes this
+more prominent. A value of 1 will prevent this side effect and a value of 2 will
+not turn the hyphen into a discretionary. Experiments with other options, like
+permitting hyphenation, of the words on both sides were discarded.

+Sometimes you won't get what you expect so a bit of explanation might help to

+linked list. In a second pass the formula will be build. This has to do with the
+fact that in order to determine the automatically chosen sizes (in for instance
+fractions) following content can influence preceding sizes. A side effect of this
+is for instance that one cannot change the definition of a font family (and

+The style switching primitives like \type {\textstyle} are turned into nodes so

+four lists being constructed of which one is used in the second pass. The fact

+{\mathstyle} primitive expands to the current style which can of course be

+method seven does the opposite, the glue is only applied when there is (x)space
+glue present too. Anything more fance, like checking the begining or end of a

+that case you could also inject glue (or set the properties of a math node)
+explicitly. So, these modes are in practice mostly useful for special purposes
+and experiments (they originate in a tracker item). Keep in mind that this glue
+is part of the math node and not always treated as normal glue: it travels with
+the begin and end math nodes. Also, method 6 and 7 will zero the skip related
+fields in a node when applicable in the first occasion that checks them
+(linebreaking or packaging).

+\startsection[title=Directions]
+
+The directional model in \LUATEX\ is inherited from \OMEGA|/|\ALEPH\ but we tried
+to improve it a bit. At some point we played with recovery of modes but that was
+disabled later on when we found that it interfered with nested directions. That
+itself had as side effect that the node list was no longer balanced with respect
+to directional nodes which in turn can give side effects when a series of dir
+changes happens without grouping.
+
+The current (0.97 onward) approach is that we again make the list balanced but
+try to avoid some side effects. What happens is quite intuitive if we forget
+about spaces (turned into glue) but even there what happens makes sense if you
+look at it in detail. However that logic makes in|-|group switching kind of
+useless when no proper nested grouping is used: switching from right to left
+several times nested, results in spacing ending up after each other due to nested
+mirroring. Of course a sane macro package will manage this for the user but here
+we are discussing the low level dir injection.
+
+This is what happens:
+
+\starttyping
+\textdir TRT nur {\textdir TLT run \textdir TRT NUR} nur
+\stoptyping
+
+This becomes stepwise:
+
+\startnarrower
+\starttyping
+injected: [+TRT]nur {[+TLT]run [+TRT]NUR} nur
+balanced: [+TRT]nur {[+TLT]run [-TLT][+TRT]NUR[-TRT]} nur[-TRT]
+result  : run {RUNrun } run
+\stoptyping
+\stopnarrower
+
+And this:
+
+\starttyping
+\textdir TRT nur {nur \textdir TLT run \textdir TRT NUR} nur
+\stoptyping
+
+becomes:
+
+\startnarrower
+\starttyping
+injected: [+TRT]nur {nur [+TLT]run [+TRT]NUR} nur
+balanced: [+TRT]nur {nur [+TLT]run [-TLT][+TRT]NUR[-TRT]} nur[-TRT]
+result  : run {run RUNrun } run
+\stoptyping
+\stopnarrower
+
+Now, in the following examples watch where we put the braces:
+
+\startbuffer
+\textdir TRT nur {{\textdir TLT run} {\textdir TRT NUR}} nur
+\stopbuffer
+
+\typebuffer
+
+This becomes:
+
+\startnarrower
+\getbuffer
+\stopnarrower
+
+Compare this to:
+
+\startbuffer
+\textdir TRT nur {{\textdir TLT run }{\textdir TRT NUR}} nur
+\stopbuffer
+
+\typebuffer
+
+Which renders as:
+
+\startnarrower
+\getbuffer
+\stopnarrower
+
+So how do we deal with the next?
+
+\startbuffer
+\def\ltr{\textdir TLT\relax}
+\def\rtl{\textdir TRT\relax}
+
+run {\rtl nur {\ltr run \rtl NUR \ltr run \rtl NUR} nur}
+run {\ltr run {\rtl nur \ltr RUN \rtl nur \ltr RUN} run}
+\stopbuffer
+
+\typebuffer
+
+It gets typeset as:
+
+\startnarrower
+\startlines
+\getbuffer
+\stoplines
+\stopnarrower
+
+We could define the two helpers to look back, pick up a skip, remove it and
+inject it after the dir node. But that way we loose the subtype information that
+for some applications can be handy to be kept as|-|is. This is why we now have a
+variant of \type {\textdir} which injects the balanced node before the skip.
+Instead of the previous definition we can use:
+
+\startbuffer[def]
+\def\ltr{\linedir TLT\relax}
+\def\rtl{\linedir TRT\relax}
+\stopbuffer
+
+\typebuffer[def]
+
+and this time:
+
+\startbuffer[txt]
+run {\rtl nur {\ltr run \rtl NUR \ltr run \rtl NUR} nur}
+run {\ltr run {\rtl nur \ltr RUN \rtl nur \ltr RUN} run}
+\stopbuffer
+
+\typebuffer[txt]
+
+comes out as a properly spaced:
+
+\startnarrower
+\startlines
+\getbuffer[def,txt]
+\stoplines
+\stopnarrower
+
+Anything more complex that this, like combination of skips and penalties, or
+kerns, should be handled in the input or macro package because there is no way we
+can predict the expected behaviour. In fact, the \type {\linedir} is just a
+convenience extra which could also have been implemented using node list parsing.
+
+Another adaptation to the \ALEPH\ directional model is control over shapes driven
+by \type {\hangindent} and \type {\parshape}. This is controlled by a new parameter
+\type {\shapemode}:
+
+\starttabulate[|cTB|c|]
+\NC   \NC \bf \type {\hangindent} \NC \bf \type {\parshape} \NC \NR
+\NC 0 \NC  normal                 \NC normal                \NC \NR

+\NC 3 \NC  mirrored               \NC mirrored              \NC \NR
+\stoptabulate
+
+The value is reset to zero (like \type {\hangindent} and \type {\parshape})
+after the paragraph is done with. You can use negative values to preven t
+this.

-\section{Two access models}
-
-Deep down in \TEX\ a node has a number which is an numeric entry in a memory
-table. In fact, this model, where \TEX\ manages memory is real fast and one of
-the reasons why plugging in callbacks that operate on nodes is quite fast too.
-Each node gets a number that is in fact an index in the memory table and that
-number often gets reported when you print node related information.
-
-There are two access models, a robust one using a so called user data object that
-provides a virtual interface to the internal nodes, and a more direct access which
-uses the node numbers directly. The first model provide key based access while
-the second always accesses fields via functions:
-
-\starttyping
-nodeobject.char
-getfield(nodenumber,"char")
-\stoptyping
-
-If you use the direct model, even if you know that you deal with numbers, you
-should not depend on that property but treat it an abstraction just like
-traditional nodes. In fact, the fact that we use a simple basic datatype has the
-penalty that less checking can be done, but less checking is also the reason why
-it's somewhat faster. An important aspect is that one cannot mix both methods,
-but you can cast both models. So, multiplying a node number makes no sense.
-
-So our advice is: use the indexed (table) approach when possible and investigate
-the direct one when speed might be an real issue. For that reason we also provide
-the \type {get*} and \type {set*} functions in the top level node namespace.
-There is a limited set of getters. When implementing this direct approach the
-regular index by key variant was also optimized, so direct access only makes
-sense when we're accessing nodes millions of times (which happens in some font
-processing for instance).
-
-We're talking mostly of getters because setters are less important. Documents
-have not that many content related nodes and setting many thousands of properties
-is hardly a burden contrary to millions of consultations.
-
-Normally you will access nodes like this:
-
-\starttyping
-local next = current.next
-if next then
-    -- do something
-end
-\stoptyping
-
-Here \type {next} is not a real field, but a virtual one. Accessing it results in
-a metatable method being called. In practice it boils down to looking up the node
-type and based on the node type checking for the field name. In a worst case you
-have a node type that sits at the end of the lookup list and a field that is last
-in the lookup chain. However, in successive versions of \LUATEX\ these lookups
-have been optimized and the most frequently accessed nodes and fields have a
-higher priority.
-
-Because in practice the \type {next} accessor results in a function call, there
-is some overhead involved. The next code does the same and performs a tiny bit
-faster (but not that much because it is still a function call but one that knows
-what to look up).
-
-\starttyping
-local next = node.next(current)
-if next then
-    -- do something
-end
-\stoptyping
-
-If performance matters you can use an function instead:

-
-The direct variants also have setters, where the discretionary setter takes three
-(optional) arguments plus an optional fourth indicating the subtype.
-
-It doesn't make sense to add getters for all fields, also because some are not
-unique to one node type. Profiling demonstrated that these fields can get
-accesses way more times than other fields. Even in complex documents, many node
-and fields types never get seen, or seen only a few times. Most functions in the
-\type {node} namespace have a companion in \type {node.direct}, but of course not

+\section{Two access models}
+
+Deep down in \TEX\ a node has a number which is an numeric entry in a memory
+table. In fact, this model, where \TEX\ manages memory is real fast and one of
+the reasons why plugging in callbacks that operate on nodes is quite fast too.
+Each node gets a number that is in fact an index in the memory table and that
+number often gets reported when you print node related information.
+
+There are two access models, a robust one using a so called user data object that
+provides a virtual interface to the internal nodes, and a more direct access which
+uses the node numbers directly. The first model provide key based access while
+the second always accesses fields via functions:
+
+\starttyping
+nodeobject.char
+getfield(nodenumber,"char")
+\stoptyping
+
+If you use the direct model, even if you know that you deal with numbers, you
+should not depend on that property but treat it an abstraction just like
+traditional nodes. In fact, the fact that we use a simple basic datatype has the
+penalty that less checking can be done, but less checking is also the reason why
+it's somewhat faster. An important aspect is that one cannot mix both methods,
+but you can cast both models. So, multiplying a node number makes no sense.
+
+So our advice is: use the indexed (table) approach when possible and investigate
+the direct one when speed might be an real issue. For that reason we also provide
+the \type {get*} and \type {set*} functions in the top level node namespace.
+There is a limited set of getters. When implementing this direct approach the
+regular index by key variant was also optimized, so direct access only makes
+sense when we're accessing nodes millions of times (which happens in some font
+processing for instance).
+
+We're talking mostly of getters because setters are less important. Documents
+have not that many content related nodes and setting many thousands of properties
+is hardly a burden contrary to millions of consultations.
+
+Normally you will access nodes like this:
+
+\starttyping
+local next = current.next
+if next then
+    -- do something
+end
+\stoptyping
+
+Here \type {next} is not a real field, but a virtual one. Accessing it results in
+a metatable method being called. In practice it boils down to looking up the node
+type and based on the node type checking for the field name. In a worst case you
+have a node type that sits at the end of the lookup list and a field that is last
+in the lookup chain. However, in successive versions of \LUATEX\ these lookups
+have been optimized and the most frequently accessed nodes and fields have a
+higher priority.
+
+Because in practice the \type {next} accessor results in a function call, there
+is some overhead involved. The next code does the same and performs a tiny bit
+faster (but not that much because it is still a function call but one that knows
+what to look up).
+
+\starttyping
+local next = node.next(current)
+if next then
+    -- do something
+end
+\stoptyping
+
+Some accessors are used frequently and for these we provide more efficient helpers:
+
+\starttabulate[|T|p|]
+\NC getnext    \NC parsing nodelist always involves this one \NC \NR
+\NC getprev    \NC used less but is logical companion to \type {getnext} \NC \NR
+\NC getboth    \NC returns the next and prev pointer of a node \NC \NR
+\NC getid      \NC consulted a lot \NC \NR
+\NC getsubtype \NC consulted less but also a topper \NC \NR
+\NC getfont    \NC used a lot in \OPENTYPE\ handling (glyph nodes are consulted a lot) \NC \NR
+\NC getchar    \NC idem and also in other places \NC \NR
+\NC getwhd     \NC returns the \type {width}, \type {height} and \type {depth} of a list, rule or
+                   (unexpanded) glyph as well as glue (its spec is looked at) and unset nodes\NC \NR
+\NC getdisc    \NC returns the \type {pre}, \type {post} and \type {replace} fields and
+                   optionally when true is passed also the tail fields. \NC \NR
+\NC getlist    \NC we often parse nested lists so this is a convenient one too \NC \NR
+\NC getleader  \NC comparable to list, seldom used in \TEX\ (but needs frequent consulting
+                   like lists; leaders could have been made a dedicated node type) \NC \NR
+\NC getfield   \NC generic getter, sufficient for the rest (other field names are
+                   often shared so a specific getter makes no sense then) \NC \NR
+\NC getbox     \NC gets the given box (a list node) \NC \NR
+\stoptabulate
+
+In the direct namespace there are more such helpers and most of them are
+accompanied by setters. The getters and setters are clever enough to see what
+node is meant. We don't deal with whatsit nodes: their fields are always accessed
+by name. It doesn't make sense to add getters for all fields, we just identifier
+the most likely candidates. In complex documents, many node and fields types
+never get seen, or seen only a few times, but for instance glyphs are candidates
+for such optimization. The \type {node.direct} interface has some more helpers.
+\footnote {We can define the helpers in the node namespace with \type {getfield}
+which is about as efficient, so at some point we might provide that as module.}
+
+The \type {setdisc} helper takes three (optional) arguments plus an optional
+fourth indicating the subtype. Its \type {getdisc} takes an optional boolean;
+when its value is \type {true} the tail nodes will also be returned. The \type
+{setfont} helper takes an optional second argument, it being the character. The
+directmode setter \type {setlink} takes a list of nodes and will link them,
+thereby ignoring \type {nil} entries. The first valid node is returned (beware:
+for good reason it assumes single nodes). For rarely used fields no helpers are
+provided and there are a few that probably are used seldom too but were added for
+consistency. You can of course always define additional accessor using \type
+{getfield} and \type {setfield} with little overhead.

+The \type {node.next} and \type {node.prev} functions will stay but for
+consistency there are variants called \type {getnext} and \type {getprev}. We had
+to use \type {get} because \type {node.id} and \type {node.subtype} are already
+taken for providing meta information about nodes. Note: The getters do only basic
+checking for valid keys. You should just stick to the keys mentioned in the
+sections that describe node properties.
+
+Some nodes have indirect references. For instance a math character refers to a
+family instead of a font. In that case we provide a virtual font field as
+accessor. So, \type {getfont} and \type {.font} can be used on them. The same is
+true for the \type {width}, \type {height} and \type {depth} of glue nodes. These
+actually access the spec node properties, and here we can set as well as get the

+\startchapter[title=Features]
+
+\startsection[title=Default features]
+
+Math fonts are loaded in so called basemode, which gives them a traditional
+treatment in the engine. However, we do support features in basemode too, so
+setting them can influence what gets passed to \TEX. Also, in math mode, some
+font features (like \type {dtls} and stylistic alternates) are applied
+dynamically.
+
+The default \type {mathematics} feature set is as follows:
+
+\showfeatureset[name=mathematics]
+
+We don't discuss the exact meaning of these options here because normally you
+don't have to deal with them. If a math font demands something special, the place
+to deal with it is the related font goodie file.
+
+This feature set is the parent of two other sets: \type {mathematics-l2r} and
+\type {mathematics-r2l}:
+
+\showfeatureset[name=mathematics-l2r]
+
+This one is the same as the parent but the right|-|to|-|left variant is
+different:
+
+\showfeatureset[name=mathematics-r2l]
+
+Eventually we need size related feature sets and again we define a parent and
+direction specific ones: \type {math-text}, \type {math-script} and \type
+{math-scriptscript}.
+
+\showfeatureset[name=math-text]
+\showfeatureset[name=math-script]
+\showfeatureset[name=math-scriptscript]
+
+The left|-|to|-|right sets \type {math-*-l2r} are:
+
+\showfeatureset[name=math-text-l2r]
+\showfeatureset[name=math-script-l2r]
+\showfeatureset[name=math-scriptscript-l2r]
+
+The right|-|to|-|left sets \type {math-*-r2l} are:
+
+\showfeatureset[name=math-text-r2l]
+\showfeatureset[name=math-script-r2l]
+\showfeatureset[name=math-scriptscript-r2l]
+
+There are a few extra sets defined but these are meant for testing or virtual
+math fonts. The reason for showing these sets is to make clear that the number of
+features is minimal and that math is a real script indeed.
+
+The \type {kern} features is questionable. In traditional \TEX\ there are kerns
+indeed but in \OPENTYPE\ math kerns are not used that way because a more advanced
+kerning feature is present (and that one is currently always enabled). We used to
+set the following but these make no sense.
+
+\starttyping
+liga=yes, % (traditional) ligatures
+tlig=yes, % tex ligatures, like -- and ---
+trep=yes, % tex replacements, like the ' quote
+\stoptyping
+
+Math fonts normally have no ligatures and supporting the \TEX\ specific ones can
+actually be annoying. So, in todays \CONTEXT\ these are no longer enabled. Just
+consider the following:
+
+\startbuffer
+$- \kern0pt -   \kern 0pt \mathchar"2D$
+$- \kern0pt --  \kern 0pt \mathchar"2D \mathchar"2D$
+$- \kern0pt --- \kern 0pt \mathchar"2D \mathchar"2D \mathchar"2D$
+\stopbuffer
+
+\typebuffer
+
+The \type {-} is mapped onto a minus sign and therefore several in succession
+become multiple minus signs. The \type {\mathchar"2D} will remain the character
+with that slot in the font so there we will see a hyphen. If we would enable the
+\type {tlig} feature several such characters would be combined into an endash or
+emdash. So how do we get these than? Because getting a hyphen directly involves a
+command, the same is true for its longer relatives: \type {\endash} and \type
+{\emdash}.
+
+\startlines
+\getbuffer
+\stoplines
+
+As convenience we have defined a special \type {\mathhyphen} command. Watch the
+fact that a text hyphen in math mode is a minus in math! As comparison we also
+show the plus sign.

+
+The \type {\framed} macro is one of the core constructors in \CONTEXT\ and it's
+used all over the place. This macro is unlikely to change its behaviour and as it
+has evolved over years it comes with quite some options and some can interfere
+with the expectations one has. In general using this macro works out well but you
+need to keep an eye on using struts and alignment.
+
+\startbuffer
+\framed{$e=mc^2$}
+\stopbuffer
+
+\typebuffer
+
+The outcome of this is:
+
+\startlinecorrection \getbuffer \stoplinecorrection
+
+There is a bit of offset (that you can set) but also struts are added as can be
+seen when we visualize them:
+
+\startlinecorrection \showstruts \getbuffer \stoplinecorrection
+
+These struts can be disabled:
+
+\startbuffer
+\framed[strut=no]{$e=mc^2$}
+\stopbuffer
+
+\typebuffer
+
+Now the result is more tight.
+
+\startlinecorrection \showstruts \getbuffer \stoplinecorrection
+
+These struts are the way to get a consistent look and feel and are used
+frequently in \CONTEXT. We mention these struts because they get in the way when
+we frame a display formula. Let's first look at what happens when we
+just package a formula in a box:
+
+\startbuffer
+\vbox\bgroup
+    \startformula
+        e = mc^2
+    \stopformula
+\egroup
+\stopbuffer
+
+\typebuffer
+
+We get:
+

+Now there are a few properties of displaymath that one needs to keep in mind when
+messing around with them this way. First of all display math is meant to be used
+as part of the page stream. This means that spacing above and below is adapted to
+what comes before and after. It also means that, because formulas can be numbered,
+we have some settings that relate to horizontal placement.
+
+The default vertical spacing is easy to get rid of:
+
+\startbuffer
+\vbox\bgroup
+    \startformula[packed]
+        e = mc^2
+    \stopformula
+\egroup
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection \start \showmakeup \getbuffer \stop \stoplinecorrection
+
+Another handy keyword is \type {tight}:
+
+\startbuffer
+\vbox\bgroup
+    \startformula[tight]
+        e = mc^2
+    \stopformula
+\egroup
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection \start \showmakeup \getbuffer \stop \stoplinecorrection
+
+We can combine these two:
+
+\startbuffer
+\vbox\bgroup
+    \startformula[packed,tight]
+        e = mc^2
+    \stopformula
+\egroup
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection \start \showmakeup \getbuffer \stop \stoplinecorrection
+
+Just in case you wonder why we need to go through these troubles: keep in mind
+that we are wrapping something (math) that normally goes in a vertical list with
+text above and below.
+
+The \type {packed} and \type {tight} options can help when we want to wrap
+a formula in a frame:
+
+\startbuffer
+\framed
+    [strut=no]
+    {
+        \startformula[packed,tight]
+            e = mc^2
+        \stopformula
+    }
+\stopbuffer
+
+\typebuffer
+
+which renders as:
+
+\startlinecorrection \getbuffer \stoplinecorrection
+
+There is a dedicated math framed instance that is tuned to give better results
+and automatically switches to math mode:
+
+\startbuffer
+\mframed {
+    e = mc^2
+}
+\stopbuffer
+
+\typebuffer
+
+becomes:
+
+\startlinecorrection \getbuffer \stoplinecorrection
+
+Framing a formula is also supported as a option, where the full power of framed can
+be applied to the formula. We will illustrate this in detail on the next pages. For this
+we use the following sample:
+
+\typefile{math-framing-001.tex}
+
+In \in {figure} [framing-flushleft], \in [framing-middle] \in {and}
+[framing-flushright] you see some combinations. You can run this example on your
+machine and see the details.
+
+\startplacefigure[location=page,reference=framing-flushleft,title={Framed formulas flushed left.}]
+    \startcombination[2*2]
+        {\typesetfile[math-framing-001.tex][page=01,height=.45\textheight]} {\tttf right + flushleft}
+        {\typesetfile[math-framing-001.tex][page=02,height=.45\textheight]} {\tttf right + flushleft}
+        {\typesetfile[math-framing-001.tex][page=07,height=.45\textheight]} {\tttf left  + flushleft + tight}
+        {\typesetfile[math-framing-001.tex][page=08,height=.45\textheight]} {\tttf left  + flushleft + tight}
+    \stopcombination
+\stopplacefigure
+
+\startplacefigure[location=page,reference=framing-middle,title={Framed formulas centered.}]
+    \startcombination[2*2]
+        {\typesetfile[math-framing-001.tex][page=03,height=.45\textheight]} {\tttf right + middle}
+        {\typesetfile[math-framing-001.tex][page=04,height=.45\textheight]} {\tttf right + middle}
+        {\typesetfile[math-framing-001.tex][page=09,height=.45\textheight]} {\tttf left  + middle + tight}
+        {\typesetfile[math-framing-001.tex][page=10,height=.45\textheight]} {\tttf left  + middle + tight}
+    \stopcombination
+\stopplacefigure
+
+\startplacefigure[location=page,reference=framing-flushright,title={Framed formulas flushed right.}]
+    \startcombination[2*2]
+        {\typesetfile[math-framing-001.tex][page=05,height=.45\textheight]} {\tttf right + flushright}
+        {\typesetfile[math-framing-001.tex][page=06,height=.45\textheight]} {\tttf right + flushright}
+        {\typesetfile[math-framing-001.tex][page=11,height=.45\textheight]} {\tttf left  + flushright + tight}
+        {\typesetfile[math-framing-001.tex][page=12,height=.45\textheight]} {\tttf left  + flushright + tight}
+    \stopcombination
+\stopplacefigure
+
+With each formula class a framed variants is automatically created:
+
+\startbuffer
+\defineformula
+  [foo]
+
+\setupformulaframed
+  [foo]
+  [frame=on,
+   framecolor=red]
+
+\startfooformula[frame]
+    e=mc^2
+\stopfooformula
+\stopbuffer
+
+\typebuffer
+
+This time you get a red frame:
+
+\getbuffer
+
+You can also frame the number, as in:
+
+\startbuffer
+\setupformulaframed[framecolor=red,frame=on,offset=1ex]
+\setupformula[option=frame,color=blue]
+\setupformula[numbercommand={\inframed[framecolor=green]}]
+
+\startplaceformula
+    \startformula
+        2 + 2 = 2x
+    \stopformula
+\stopplaceformula
+\stopbuffer
+
+\typebuffer
+
+The boxes get properly aligned:
+
+\start \showboxes \getbuffer \stop

+
+Numbering equations can be a bit of a mess. Formuals can be unnumbers, numbered,
+numbered with an associated reference. Numbers can go on the while formula and on
+the rows in an alignment. Combine that with positioning left or right and left or
+righ taligned formulas and the picture gets complicated. When something turns out
+wrong, just let me know and the respective branch in the code can be adapted. Here

+\startchapter[title=Vertical spacing]
+
+The low level way to input inline math in \TEX\ is
+
+\starttyping
+$ e = mc^2 $
+\stoptyping
+
+while display math can be entered like:
+
+\starttyping
+$$ e = mc^2 $$
+\stoptyping
+
+The inline method is still valid, but for display math the \type {$$} method
+should not be used. This has to do with the fact that we want to control spacing
+in a consistent way. In \CONTEXT\ the vertical spacing model is rather stable
+although in \MKIV\ the implementation is quite different. It has always been a
+challenge to let this mechanism work well with space round display formulas. This
+has to do with the fact that (in the kind of documents that we have to produce)
+interaction with already present spacing is somewhat tricky.
+
+Of course much can be achieved in \TEX\ but in \CONTEXT\ we need to have control
+over the many mechanisms that can interact. Given the way \TEX\ handles space
+around display math there is no real robust solution possible that gives visually
+consistent space in all cases so that is why we basically disable the existing
+spacing model. Disabling is easier in \LUATEX\ and recent versions of \MKIV\ have
+been adapted to that.
+
+In pure \TEX\ what happens is this:
+
+\startbuffer
+$$ x $$
+\stopbuffer
+
+\typebuffer \par \start \showboxes \getbuffer \par \stop
+
+A horizontal box (visualized by the thin rule on its baseline) get added which
+triggers a baselineskip. Then the formula is put below it. We can get rid of that
+box with \type {\noindent}:
+
+\startbuffer
+\noindent $$ x $$
+\stopbuffer
+
+\typebuffer \par \start \showboxes \getbuffer \par \stop
+
+In addition (not shown here) vertical space is added before and after the formula
+and left- and rightskip on the edges. In fact typesetting display math goes like this:
+
+\startitemize[packed]
+    \startitem
+        typeset the formula using display mode and wrap it in a box
+    \stopitem
+    \startitem
+        add an equation number, if possible in the same line, otherwise on a line
+        below
+    \stopitem
+    \startitem
+        in the process center the formula using the available display width and
+        required display indentation
+    \stopitem
+    \startitem
+        add vertical space above and below (depending also in displays being
+        short in relation to the previous line
+    \stopitem
+    \startitem
+        at the same time also add penalties that determine the break across
+        pages
+    \stopitem
+\stopitemize
+
+Apart from the spacing around the formula and the equation number, typesetting is
+not different from:
+
+\starttyping
+\hbox {$ \displaystyle x $}
+\stoptyping
+
+So this is what we will use by default in \CONTEXT\ in order to better control
+spacing as spacing around math is a sensitive issue. Because math itself can have
+a narrow band, for instance a lone $x$, or relative much depth, as with $y$, or
+both depth and height as in $(1,2)$ and $x^2 + y_2$ and because a preceding line
+can have no or little depth and a following line little height, the visual
+appearance can become inconsistent. The default approach is to force consistent
+spacing, but when needed we can implement variants.
+
+Spacing around display math is set up with \type {\setupformulas}:
+
+\starttyping
+  \setupformulas
+    [spacebefore=big,
+     spaceafter=big]
+\stoptyping
+
+When the whitespace is larger that setting wins because as usual the larger
+of blanks or whitespace wins.
+
+% \showdefinition[setupformula]
+% \showdefinition[setupmathematics]
+
+In \in {figures} [whitespace-no], \in {figures} [whitespace-medium] \in {and}
+[whitespace-big] we see how things interact. We show lines with and without
+maximum line height and depth (enforced by struts) alongside.

+Because we want to have control over the placement of the formula number but also
+want to be able to align the formula with the left or right edge of the text
+area, we don't use the native display handler by default. We still have a way to
+force this, but this is only for testing purposes. By default a formula is placed
+centered relative to the current text, including left and right margins.

+and the same with margins:
+
+\start \getbuffer[setting] \getbuffer[demo] \stop
+

+
+When the \type {margin} option is set to \type {standard} or \type {yes} the

+Spacing is a trade off because there is no way to predict all usage. Of course a
+font can be very detailed in where italic correction is to be applied and how
+advanced stepwise kerns are used, but not many fonts have extensive information.
+Here are some differences in rendering. In \OPENTYPE\ the super- and subscript of
+an integral are moved right and left half of the italic correction.

+There might be fonts out there where the italic correction is supposed to be
+added to the width of a glyph. In that case the following trick can be tried:
+
+\starttyping
+\definefontfeature[mathextra][italicwidths=yes] % fix latin modern
+\stoptyping
+
+in which case the following might look better:
+
+\starttyping
+$\left|V\right| = \left|W\right|$
+\stoptyping
+
+Of course better is to fix the font.

+This document shows a few formulas coded in \MATHML\ and typeset by \CONTEXT. The
+examples are taken from an old copy of \quote {Handbook of Chemistry and Physics}
+as well as \quote {Wiskunde voor het HBO (R.~van Asselt et al.)}. We assume no
+responsibility for the coding being 100\% all correct.
+
+These examples are typeset using the default settings. There are several ways to
+influence the look and feel of a formula. Details on how to process \MATHML\ can
+be found in the \XML\ related documentation that comes with \CONTEXT.
+
+You can get more information on \CONTEXT\ at our website, in \TEX\ usergroup
+publications and in (the archives of) the \CONTEXT\ mailing list.

+
+It is a well known fact that \TEX\ can do a pretty good job on typesetting math.
+This is one reason why many scientific articles, papers and books are typeset
+using \TEX. However, in these days of triumphing angle brackets, coding in \TEX\
+looks more and more out of place.
+
+From the point of view of an author, coding in \TEX\ is quite natural, given that
+some time is spent on reading the manuals. This is because not only the natural
+flow of the definition suits the way mathematicians think, but also because the
+author has quite some control over the way his thoughts end up on paper. It will
+be no surprise that switching to a more restricted way of coding, which also
+demands more keystrokes, is not beforehand considered to be better.
+
+There are however circumstances that one wants to share formulas (or
+formula||like specifications) between several applications, one of which is a
+typesetting engine. In that case, a bit more work now, later saves you some
+headaches due to keeping the different source documents in sync.
+
+The moment coding math in \XML\ is discussed, those in favour stress that coding
+can be eased by using appropriate editors. Here we encounter a dilemma. For
+optimal usage, one should code in terms of content, that is, the principles that
+are expressed in a formula. Editors are not that strong in this area, and if they
+would be, editing would be not that much different from traditionally editing
+formulas: just keying in ideas using code that at first sight looks obscure. A
+more graphical oriented editor can help authors to compose formulas, but the
+underlaying coding will mainly be in terms of placing glyphs and boxes, and as a
+result the code will hardly be usable in other applications.
+
+So either we code in terms of concepts, which permits sharing code among
+applications, and poses strong limitations on the influence of authors on the
+visual appearance. Or we use an interactive editor to fine tune the appearance of
+a formula and take for granted that reuse will be minimal or suboptimal.
+
+In the following chapters we will discuss the mathematical language \MATHML\ in
+the perspective of typography. As a typesetting vehicle, we have used \CONTEXT.
+However, the principles introduced here and the examples that we provide are
+independent of \CONTEXT. For a more formal exploration we recommend the \MATHML\
+specification.
+
+This document is dedicated to all those \CONTEXT\ users who like typesetting
+math. I'm sure that my father, who was a math teacher, would have liked
+proofreading this document. His absence was compensated by Tobias Burnus, Wang
+Lei, Ton Otten, and later members of the \CONTEXT\ mailing list who carefully
+read the text, corrected the errors in my math, tested the functionality, and
+made suggestions. Any remaining errors are mine.
+
+When we started supporting \MATHML\ we were under the impression that it would be
+accepted and take of fast, but we were wrong. It toke much more than a decade for
+instance to see browsers support rendering. Being involved in typesetting
+educational content from \XML\ files, we could use this subsystem ourselves, and
+this was useful in the sense that we ran into lots of contradicting and
+suboptimal \MATHML\ code. However, the most interesting application has always
+been in the math4all project, where we went from \TEX\ math, via content \MATHML\
+and open math to presentational \MATHML. Nowadays web usage drives the coding and
+limitations in other programs (and rendering) are sometimes compensated by coding
+and our renderer then has to be able to recover nicely. Thanks to the enormous
+productivity of the main math4all author Frits Spijkers and the careful checking
+by my collegue Ton Otten, we could always keep op well. Development and support
+of the \CONTEXT\ typesetting system is mostly done without any commercial
+benefits and the amount of free time that we spend on it and especially its more
+obscure properties like \MATHML\ is compensated by flexible and tolerant users
+like them.
+
+One problem is that our own usage of \MATHML\ changes over time. Some of our
+projects demand the use of this standard but at the same time the used sources
+need to satisfy other needs, for instance rendering on the web. For some 15 years
+now the changing demands and quality have made us oscillate between (often
+suboptimal) solutions that deal with the suboptimal code that comes from
+compromises. For instance the mentioned project is now using a mixture of
+\MATHML\ and so called \ASCII math because that is the only way the enormous
+amount of math code can be rendered on the web. And even there we need to bend
+the rules, for instance to compensate for missing features or cultural
+differences. Eventually I will rewrite the rendering from scratch but I need time
+and a very good reason for that.
+
+This version of the manual is produced by \CONTEXT\ \MKIV\ and is also used as
+testcase. The version rendered at \PRAGMA\ uses the Lucida Bright fonts. These
+can be bought at \goto {www.tug.org} [url(http://{www.tug.org})] for a reasonable
+low price and are really worth the money.

+\startsection[title={backgrounds}]
+
+\MATHML\ showed up in the evolving vacuum between structural \SGML\ markup and
+presentational \HTML. Both \SGML\ and \HTML\ can be recognized by angle brackets.
+The disadvantage of \SGML\ was that it was so open ended, that general tools
+could hardly be developed. \HTML\ on the other hand was easy to use and became
+extremely popular and users as well as software vendors quickly spoiled the
+original ideas and created a mess. \SGML\ never became really popular, but thanks
+to \HTML\ people became accustomed to that kind of notation. So, when \XML\ came
+around as a more restricted cousin of \SGML, the world was kind of ready for it.
+It cannot be denied that by some clever marketing many of today's users think
+that they use something new and modern, while we are actually dealing with
+something from the early days of computing. A main benefit of \XML\ is that it
+brought the ideas behind \SGML\ (and medium neutral coding in general) to the
+users and at the same time made a major cleanup of \HTML\ possible.
+
+About the same time, \MATHML\ was defined, both to bring math to the \WWW, and to
+provide a way of coding math that will stimulate sharing the same code between
+different applications. At the end of 2000, the \MATHML\ version~2 draft became a
+recommendation. In the process of rewriting the interpreter for \CONTEXT\ \MKIV\
+mid 2008 a draft of \MATHML\ version~3 has been used.
+
+Now, imagine that we want to present a document on the internet using a format
+like \HTML, either for viewing or for being spoken. Converting text and graphics
+is, given proper source coding, seldom a problem, but converting formulas into
+some angle bracket representation is more tricky. A way out of this is \MATHML's
+presentational markup.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <mrow>
+    <mi> a </mi>
+    <mo> + </mo>
+    <mi> b </mi>
+    <mo> = </mo>
+    <mi> c </mi>
+  </mrow>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+This simple formula, when coded in \TEX, looks like:
+
+\starttyping
+$$ a + b = c $$
+\stoptyping
+
+In presentational \MATHML\ we get:
+
+\typebuffer
+
+In presentational \MATHML, we use mostly begintags (\type {<mi>}) and end tags
+(\type {</mi>}). The \mmlelement {mrow} element is the basic building block of a
+formula. The \mmlelement {mi} element specifies a math identifier and \mmlelement
+{mo} is used for operators. In the process of typesetting, both are subjected to
+interpretation in order to get the best visualization.
+
+Converting \TEX\ code directly or indirectly, using printable output or even
+in||memory produced math lists, has been one of the driving forces behind
+presentational \MATHML\ and other math related \DTD's like \EUROMATH. One may
+wonder if there are sound and valid reasons for going the opposite way. You can
+imagine that a converter from \TEX\ to \MATHML\ produces \mmlelement {menclose},
+\mmlelement {mspace}, \mmlelement {mstyle} and other elements that can have many
+spacing related attributes, but I wonder if any author is willing to think in
+those quantities. Visual editors of course are good candidates for producing
+presentational \MATHML.
+
+But wouldn't it be more efficient if we could express ideas and concepts in such
+a way that they could be handled by a broad range of applications, including a
+typesetting engine? This is why, in addition to presentational \MATHML, there is
+also content \MATHML. The previous formula, when coded in such a way, looks like:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <eq/>
+    <apply> <plus/>
+      <ci> a </ci>
+      <ci> b </ci>
+    </apply>
+    <ci> c </ci>
+  </apply>
+</math>
+\stopbuffer
+
+\typebuffer
+
+This way of defining a formula resembles the so called polish (or stackwise)
+notation. Opposite to presentational markup, here a typesetting engine has to
+find out in what order and what way the content has to be presented. This may
+seem a disadvantage, but in practice implementing content markup is not that
+complicated. The big advantage is that, once we know how to typeset a concept,
+\TEX\ can do a good job, while in presentational markup much hard coded spacing
+can spoil everything. One can of course ignore specific elements, but it is more
+safe to start from less and enhance, than to leave away something with unknown
+quantities.
+
+Instead of using hard coded operators as in presentational \MATHML, content
+markup uses empty elements like \type {<plus/>}. Many operators and functions are
+predefined but one can also define his own; in \MATHML~3 this is further extended
+by adopting \OPENMATH\ as variant.
+
+Of course the main question to be answered now is to what extent the author can
+influence the appearance of a formula defined in content markup. Content markup
+has the advantage that the results can be more consistent, but taking away all
+control is counterproductive. The \MATHML\ level~2 draft mentions that this level
+covers most of the pre university math. If so, that is a proper starting point,
+but especially educational math often has to be typeset in such ways that it
+serves its purpose. Also, (re|)|using the formulas in other applications
+(simulators and alike) is useful in an educational setting, so content markup is
+quite suitable.
+
+How do we combine the advantages of content markup with the wish of an author to
+control the visual output and at the same time get an as high as possible typeset
+result. There are several ways to accomplish this. One is to include in the
+document source both the content markup and the \TEX\ specific code.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <semantics>
+    <apply> <eq/>
+      <apply> <plus/>
+        <ci> a </ci>
+        <ci> b </ci>
+      </apply>
+    </apply>
+    <ci> c </ci>
+    <annotation encoding="TeX">a+b=c</annotation>
+  </semantics>
+</math>
+\stopbuffer
+
+\typebuffer
+
+The \mmlelement {annotation} element is one of the few that is permitted inside
+the \mmlelement {math} element. In this example, we embed pure \TEX\ code, which,
+when enabled is typeset in math mode. It will be clear that for a simple formula
+like this one, such redundant coding is not needed, but one can imagine more
+complicated formulas. Because we want to limit the amount of work, we prefer just
+content markup. \blank {\it Remark: Some characters, fillers or whatever may not
+show up. This is due to the fact that the relevant tables for \CONTEXT\ \MKIV\
+are defined stepwise. In due time most relevant symbols will be accessible.}
+
+\stopsection
+
+\startsection[title={two methods}]
+
+The best way to learn \MATHML\ is to key in formulas, so that is what we did as
+soon as we started adding \MATHML\ support to \CONTEXT. In some areas, \MATHML\
+provides much detail (many functions are represented by elements) while in other
+areas one has to fall back on the more generic function element or a full
+description. Compare the following definitions:
+
+\startbuffer[a]
+<document>
+  <math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <sin/> <ci> x </ci> </apply>
+  </math>
+  <math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <mrow> <mi> sin </mi> <mi> x </mi> </mrow>
+  </math>
+</document>
+\stopbuffer
+
+\typebuffer[a]
+
+We prefer the first definition because it is more structured and gives more
+control over the result. There is only one \quote {unknown} quantity, $x$, and
+from the encapsulating element \mmlelement {ci} we know that it is an identifier.
+
+\processxmlbuffer[a]
+
+In the content example, from the \mmlelement {apply} \mmlelement {sin} we can
+deduce that the following argument is an operand, either an \mmlelement {apply},
+or a \mmlelement {ci} or \mmlelement {cn}. In the presentational alternative, the
+following elements can be braces, a math identifier, a row, a sequence of
+identifiers and operators, etc. There, the look and feel is hard coded.
+
+\startbuffer[b]
+<?context-mathml-directive function reduction no ?>
+\stopbuffer
+
+\typebuffer[b]
+
+This directive, either issued in the \XML\ file, or set in the style file,
+changes the appearance of the function, but only in content markup. It is because
+of this feature, that we favour content markup.
+
+\processxmlbuffer[b,a]
+
+Does this mean that we can cover everything with content markup? The answer to
+this is still unclear. Consider the following definition.
+
+\processxmlfile {pc-i-380.xml}
+
+Here we combine several cases in one formula by using $\pm$ and $\mp$ symbols.
+Because we only have \mmlelement {plus} and \mmlelement {minus} elements, we have
+to revert to the generic function element \mmlelement {fn}. We show the complete
+definition of this formula.
+
+\typefile {pc-i-380.xml}
+
+The \MATHML\ parser and typesetting engine have to know how to handle these
+special cases, because the visualization depends on the function (or operator).
+Here both composed signs are treated like the plus and minus signs, but in other
+cases an embraced argument may be needed.

+
+If a document contains presentational \MATHML, there is a good chance that the
+code is output by an editor. Here we will discuss the presentation elements that
+make sense for users when they want to manually code presentational \MATHML. In
+this chapter we show the default rendering, later we will discuss options.
+
+Although much is permitted, we advise to keep the code as simple as possible,
+because then \TEX\ can do a rather good job on interpreting and typesetting it.
+Just let \TEX\ take care of the spacing.
+
+\stopsection
+
+\startsection[title={mi, mn, mo}]
+
+Presentational markup comes down to pasting boxes together in math specific ways.
+The basic building blocks are these three character elements.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <mrow>

+\NC \mmlelement {mo} \NC operator   \NC surrounded by specific spacing     \NC \NR
+\HL
+\stoptabulate
+
+Because numbers are taken from an upright font, special numbers are taken care of
+automatically. Here are some from the \MATHML\ specification:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <mrow>
+    <mn> 2          </mn> <mtext>&nbsp;&nbsp;</mtext>

+    <mn> twenty one </mn> <mtext>&nbsp;&nbsp;</mtext>
+  </mrow>
+</math>
+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+Special characters can be accessed by their \UNICODE\ point or by a corresponding
+entity. For some reason there is quite some duplication in entities, but we don't
+bother too much about it because after all \UNICODE\ math (which has its own
+peculiarities) is the way to go. The specification has this somewhat strange
+formula definition:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <mrow>
+    <mn> 2 </mn>
+    <mo> + </mo>

+\stopbuffer

+And:
+
+\startbuffer

+    </mrow>
+  </mfrac>
+</math>
+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+Visualizing the \mmlelement {mo} element involved some heuristics. For instance
+the size of fences depends on what they fence. In the following case you see how
+we can influence this. For practical pusposes we only support size~1.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">

+
+The previous example demonstrated the use of \mmlelement {mrow}, the element that
+is used to communicate the larger building blocks. Although this element from the
+perspective of typesetting is not always needed, by using it, the structure of
+the formula in the document source is more clear. There is some messy magic going
+on when we try to fake fenced expressions.
+

+
+Addition, subtraction and multiplication is hard coded using the \mmlelement {mo}
+element with $+$, $-$, and $\times$ (or nothing). You can use $/$ for division,
+but for more complicated formulas you have to fall back on fraction building.
+This is why \MATHML\ provides the \mmlelement {mfrac}.
+
+\startbuffer

+\processxmlbuffer \typebuffer

+You can change the width of the rule, but this is generally a bad idea. For

+\stopsection
+
+\startsection[title={mfenced}]
+
+Braces are used to visually group sub||expressions. In presentational \MATHML\
+you can either hard code braces, or use the \mmlelement {mfenced} element to
+generate delimiters automatically. In \CONTEXT, as much as possible, the
+operators and identifiers are interpreted, and when recognized treated according
+to their nature.
+
+\startbuffer

+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+The fencing symbols adapt their size to the content. Their dimensions also depend
+on the way math fonts are defined. The standard \TEX\ fonts will give the same
+height of braces around $x$ and $y$, but in other fonts the $y$ may invoke
+slightly larger ones.

+If you put text in a \mmlelement {mi} element, it will come out rather ugly. This

+You may have noticed that we prefer content \MATHML\ over presentational \MATHML.

+you to read the next chapter too.

+\startchapter[title={Content markup}]
+
+\startsection[title={introduction}]
+
+In this chapter we will discuss the \MATHML\ elements from the point of view of
+typesetting. We will not pay attention to other rendering techniques, like speech
+generation. Some elements take attributes and those often make more sense for
+other applications than for a typesetting engine like \TEX, which has a strong
+math engine that knows how to handle math.
+
+One of the most prominent changes in \MATHML~3 is support for an \OPENMATH\ like
+coding. Here the \mmlelement {csymbol} takes the place of the empty element as
+first argument of an \mmlelement {apply}. There are more symbols in \OPENMATH\
+then we supported in the interpreter, but in due time (depending on demand) we
+will add more. At the time of writing this the draft was really a draft which
+made it hard to grasp all the implications for rendering so we probably need to
+overhaul the code sometime in the future.
+
+Another change is the usage of \mmlelement {apply} that has been delegated to
+\mmlelement {bind}. One may wonder why this hadn't happen before. For the moment
+we treat the \mmlelement {bind} as if it were an \mmlelement {apply}.
+
+\stopsection
+
+\startsection[title={apply}]
+
+If you are dealing with rather ordinary math, you will only need a subset of
+content \MATHML. For this reason we will start with the most common elements.
+When you key in \XML\ directly, you will encounter the \mmlelement {apply}
+element quite often, even in a relatively short formula like the following.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <minus/>
+        <cn> 1 </cn>
+    </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+In most cases the \mmlelement {apply} element is followed by a specification
+disguised as an empty element.
+
+Later we will see more complex examples but here we already show the different
+ways of encoding. First we show the traditional \MATHML~2 method:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <forall/>
+        <bvar> <ci>x</ci> </bvar>
+        <apply> <geq/>
+            <ci>x</ci>
+            <cn>4</cn>
+        </apply>
+    </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+This is now called \quote {pragmatic} \MATHML. Using symbols and \mmlelement
+{bind} this becomes \quote {strict} \MATHML:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="3.0">
+    <bind> <csymbol cd="quant1">forall</csymbol>

+The \mmlelement {selector} element can be used to index a matrix cell or

+A more common usage of the selector is the following:

+\startsection[title={introduction}]
+
+The advantage of presentational markup is that you can build complicated formulas
+using super- and subscripts and other elements. The drawback is that the look and
+feel is rather fixed and cannot easily be adapted to the purpose that the
+document serves. Take for instance the difference between
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <log/>
+    <logbase> <cn> 2 </cn> </logbase>

+and
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <?context-mathml-directive log location left ?>
+  <apply> <log/>
+    <logbase> <cn> 2 </cn> </logbase>
+    <ci> x </ci>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+Both formulas were defined in content \MATHML, so no explicit super- and
+subscripts were used. In the next chapter we will see how to achieve such
+different appearances.
+
+There are situations where content \MATHML\ is not rich enough to achieve the
+desired output. This omission in content \MATHML\ forces us to fall back on
+presentational markup.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <eq/>
+    <ci> <msub> <mi> P </mi> <mi> 1 </mi> </msub> </ci>
+    <ci> <msub> <mi> P </mi> <mi> 2 </mi> </msub> </ci>
+    <apply> <approx/>

+      <cn> 1 </cn>
+    </apply>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+Here we used presentational elements inside a content \mmlelement {ci} element.
+We could have omitted the outer \mmlelement {ci} element, but since the content
+\MATHML\ parser may base its decisions on the content elements it finds, it is
+best to keep the outer element there.
+
+\typebuffer
+
+The lack of an index element can be quite prominent. For instance, when in an
+expose about rendering we want to explore the mapping from coordinates in user
+space to those in device space, we use the following formula.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">

+
+Some elements can be tuned by changing their attributes. Especially when formulas
+are defined by a team of people or when they are taken from a repository, there
+is a good chance that inconsistencies will show up.
+
+In \CONTEXT, you can influence the appearance by setting the typesetting
+parameters of (classes of) elements. You can do this either by adding processing
+instructions, or by using the \CONTEXT\ command \type {\setupMMLappearance}.
+Although the first method is more in the spirit of \XML, the second method is
+more efficient and consistent. As a processing instruction, a directive looks
+like:
+
+\starttyping
+<?context-mathml-directive element key value ?>
+\stoptyping
+
+This is equivalent to the \CONTEXT\ command:
+
+\starttyping
+\setupMMLappearance [element] [key=value]
+\stoptyping
+
+Some settings concern a group of elements, in which case a group classification
+(like \type {sign}) is used.
+
+\startsection[title={scripts}]
+
+By default, nested super- and subscripts are kind of isolated from each other. If
+you want a combined script, there is the \mmlelement {msubsup}. You can however
+force combinations with a directive.

+
+The core element of \MATHML\ is \mmlelement {apply}. Even simple formulas will
+often have more than one (nested) \mmlelement {apply}. The most robust way to
+handle nested formulas is to use braces around each sub formula. No matter how
+robust this is, when presented in print we want to use as less braces as
+possible. The next example shows addition as well as subtraction.
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <plus/>
+    <cn> 7 </cn>
+    <cn> 5 </cn>
+    <apply> <minus/>
+      <cn> 3 </cn>
+    </apply>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer \typebuffer
+
+In principle subtraction is adding negated numbers, so it would have been natural
+to have just an addition (\mmlelement {plus}) and negation operator. However,
+\MATHML\ provides both a \mmlelement {plus} and \mmlelement {minus} operator,
+where the latter can be used as a negation. So in fact we have:
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <?context-mathml-directive sign reduction no ?>
+  <apply> <plus/>
+    <cn> 7 </cn>
+    <cn> 5 </cn>
+    <apply> <minus/>
+      <cn> 3 </cn>
+    </apply>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+Now imagine that a teacher wants to stress this negation in the way presented
+here, using parentheses. Since all the examples shown here are typeset directly
+from the \MATHML\ source, you may expect a solution, so here it is:
+
+\typebuffer
+
+By default signs are reduced, but one can disable that at the document and|/|or
+formula level using a processing instruction at the top of the formula. There are
+of course circumstances where the parentheses cannot be left out.

+Another place where parentheses are not needed is the following:

+  </apply>
+</math>
+\stopbuffer
+
+\typebuffer
+
+This means that the interpreter of this kind of \MATHML\ has to analyze child
+elements in order to choose the right way to typeset the formula. The output will
+look like:
+
+\processxmlbuffer
+
+By default, as less braces as possible are used. As demonstrated, a special case
+is when \mmlelement {plus} and \mmlelement {minus} have one sub element to deal
+with. If you really want many braces there, you can turn off sign reduction.

+\startchapter[title={Typesetting modes}]
+
+Math can be typeset inline or display. In order not to widen up the text of a
+paragraph too much, inline math is typeset more cramped. Since \MATHML\ does
+provide just a general purpose \mmlelement {math} element we have to provide the
+information needed using other elements. Consider the following text.
+
+\startbuffer
+<document>
+To what extent is math supposed to reflect the truth and nothing but
+the truth? Consider the simple expression
+    <math xmlns="http://www.w3c.org/mathml" version="2.0">
+        <apply> <eq/>
+            <cn> 10 </cn>
+            <apply> <plus/>
+                <cn> 3 </cn>
+                <cn> 7 </cn>
+            </apply>
+        </apply>
+    </math>. Many readers will consider this the truth, but then,
+can we assume that the decimal notation is used?
+
+<formula>
+  <math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <eq/>
+      <cn> 10 </cn>
+      <apply> <plus/>
+        <cn> 3 </cn>
+        <ci> x </ci>
+      </apply>
+    </apply>
+  </math>
+</formula>
+
+In many elementary math books, you can find expressions like the
+previous. Because in our daily life we use the decimal numbering system,
+we can safely assume that
+    <math xmlns="http://www.w3c.org/mathml" version="2.0">
+        <apply> <eq/>
+            <ci> x </ci>
+            <cn> 7 </cn>
+        </apply>
+    </math>. But, without explicitly mentioning this boundary condition,
+more solutions are correct.
+
+<formula label="octal" sublabel="a">
+  <math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <eq/>
+      <cn> 10 </cn>
+      <apply> <plus/>
+        <cn> 3 </cn>
+        <cn> 5 </cn>
+      </apply>
+    </apply>
+  </math>
+</formula>
+
+In <textref label="octal">formula</textref> we see an at first sight
+wrong formula. But, if we tell you that octal numbers are used, your
+opinion may change instantly. A rather clean way out of this confusion
+is to extend the notation of numbers by explicitly mentioning the base.
+
+<subformula label="octal base" sublabel="b">
+  <math xmlns="http://www.w3c.org/mathml" version="2.0">
+    <apply> <eq/>
+      <cn type="integer" base="8"> 10 </cn>
+      <apply> <plus/>
+        <cn type="integer" base="8"> 3 </cn>
+        <cn type="integer" base="8"> 5 </cn>
+      </apply>
+    </apply>
+  </math>
+</subformula>
+
+Of course, when a whole document is in octal notation, a proper
+introduction is better than annotated numbers as used in <textref
+label="octal base">formula</textref>.

+
+In terms of \XML\ this can look like:
+
+\typebuffer
+
+Math that is part of the text flow is automatically handled as inline math. If
+needed you can encapsulate the code in an \mmlelement {imath} environment.
+Display math is recognized as such when it is a separate paragraph, but since
+this is more a \TEX\ feature than an \XML\ one, you should encapsulate display
+math either in a \mmlelement {dmath} element or in a \mmlelement {formula} or
+\mmlelement {subformula} element.
+
+For a while you can use attribute \type {mode} with values \type {display} or
+\type {inline}. Recent \MATHML\ specifications provide the \type {display}
+attribute with values \type {block} or \type {inline}. We support both.
+
+\stopchapter
+
+\startchapter[title={Getting started}]
+
+A comfortable way to get accustomed to \MATHML\ is to make small documents of the
+following form:
+
+\starttyping
+\usemodule[mathml]
+
+\starttext
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <cos/>
+    <ci> x </ci>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+\stoptext
+\stoptyping
+
+As you see, we can mix \MATHML\ with normal \TEX\ code. A document like this is
+processed in the normal way using the \type {context} command. If you also want
+to see the original code, you can say:
+
+\starttyping
+\usemodule[mathml]
+
+\starttext
+
+\startbuffer
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <cos/>
+    <ci> x </ci>
+  </apply>
+</math>
+\stopbuffer
+
+\processxmlbuffer
+
+\typebuffer
+
+\stoptext
+\stoptyping
+
+Like \TEX\ and \METAPOST\ code, buffers can contain \MATHML\ code. The advantage
+of this method is that we only have to key in the data once. It also permits you
+to experiment with processing instructions.
+
+\starttyping
+\startbuffer[mml]
+<math xmlns="http://www.w3c.org/mathml" version="2.0">
+  <apply> <log/>
+    <logbase> <cn> 3.5 </cn> </logbase>
+    <ci> x </ci>
+  </apply>
+</math>

+
+If you like coding your documents in \TEX\ but want to experiment with \MATHML,
+combining both languages in the way demonstrated here may be an option. When you
+provide enough structure in your \TEX\ code, converting a document to \XML\ is
+then not that hard to do. Where coding directly in \XML\ is kind of annoying,
+coding \MATHML\ is less cumbersome, because you can structure your formulas
+pretty well, especially since the fragments are small so that proper indentation
+is possible.
+
+\stopchapter
+
+\startchapter[title={Bidi}]
+
+Support for bidirectional math is not entirely trivial as it demands a font that
+supports it. When they were released, the stix fonts were not that useable and
+Khaled Hosny turned them into the xits fonts that are now quite complete and
+useable in an \OPENTYPE\ and \UNICODE\ environment. He also added support for
+right to left math.
+
+Normally you will only use that in a right to left typeset document, in which
+case you have a setup like this:
+
+\starttyping
+\setuptobodyfont
+  [xitsbidi]
+
+\setupalign
+  [r2l]
+
+\setupmathematics
+  [align=r2l]
+
+\starttext
+
+Some text.
+
+\startformula \sqrt{ف^2\over 4ب} \stopformula
+
+Some more text
+
+\stoptext
+\stoptyping
+
+As \MATHML\ has no global settings you need to control it specifically. At some
+point we might decide to provide some global flags but that depends on how the
+general bidi layout machinery evolves. Here we just stick to an example:
+
+\startbuffer[test]
+<math xmlns="http://www.w3.org/1998/Math/MathML" dir="rtl">
+    <msqrt>
+        <mfrac>
+            <msup><mi>ف</mi><mn>2</mn></sup>
+            <mrow><mn>4</mn><mi>ب</mi></mrow>
+        </mfrac>
+    </msqrt>
+</math>
+\stopbuffer
+
+\typebuffer[test]
+
+\start
+    \switchtobodyfont[xitsbidi]
+    \xmlprocessbuffer{main}{test}{}
+    \par
+\stop
+
+The order of input is still rather left to right which makes sense as we're sort
+of structuring the math input.
+
+\stopchapter
+
+\startchapter[title={OpenMath}]
+
+Because \OPENMATH\ is now a subset of \MATHML\ we can to some extend also support
+this coding. We do a straightforward remapping to content \MATHML\ so any
+rendering that is supported there is also supported in the equivalent \OPENMATH\
+code.

+Because in practice we may use a mixture of math encodings this can come in handy
+because it saves conversion of the \XML\ source.
+
+\stopchapter
+
+\startchapter[title={CalcMath}]
+
+We support two types of annotation markup: \TEX\ (\type {tex}) and what we call
+\quote {calculator math} (\type {calcmath}). The second type is also available
+directly. Inline calcmath is coded using the \mmlelement{icm} element.
+
+\startbuffer

+
+If one edits the \XML\ file directly this can type quite some coding. For more
+complex formulas one can revert to content \MATHML, or when interactivity is
+needed to \OPENMATH.
+
+The argument that one should use a dedicated editor for math instead is not that
+convincing for authors who have to key on lots of small snippets of math. And one
+can always transform this code in its more bloated variant. The calcmath
+converter is dedicated to Frits Spijkers, author of Dutch math schoolbooks and
+fluent in all those math encodings methods we force upon him. The code resembles
+that used in the calculators at schools and we used it in projects with computer
+aided feedback where students had to key in math. When there is demand for this
+input method we will provide more details.
+
+\stopchapter
+
+\startchapter[title={AsciiMath}]
+
+A few years back we included some basic support for \ASCIIMATH\ as a proof of
+concept not knowing that one day we were forced to fully support it in a project.
+In one of our projects \CONTEXT\ is the backend for generating math books for
+high school math. Input is \XML\ and math is coded in presentational \MATHML. We
+should say \quotation {was coded}, because in the Spring of 2014 another party in
+the project (the one responsible for the web part) converted the \MATHML\ into
+\ASCIIMATH\ on behalve of their web authoring tool.
+
+Where we would have chosen to use the \MATHML\ annotation attribute, they had
+chosen to flatten the structured \MATHML\ into less structured \ASCIIMATH. And
+there was no way back. We're talking of tens of thousands of files here.
+\footnote {Around the same time Google decided to drop native \MATHML\ support
+from Chrome so one might wonder why \MATHML\ was developed in the first place.}
+
+On the web \ASCIIMATH\ is mostly interpreted by MathJax's \JAVASCRIPT\ in
+combination with \CSS. Since we didn't want to depend on a \JAVASCRIPT\
+conversion in \CONTEXT\ we started to completely rewrite our \ASCIIMATH\ module.
+We also needed a bit more control in order to meet specific demands of the
+publisher, like formatting numbers, support for characters not in the normal
+repertoire, checking and tracing, and the speed of rendering had not to be
+affected.
+
+If you invoke the \ASCIIMATH\ module with \typ {\usemodule [asciimath]} the
+command \type {\asciimath{...}} is available for testing purposes. Within the
+curly brackets you can type an \ASCIIMATH\ expression.
+
+Normally an \ASCIIMATH\ expression in \XML|/|\HTML\ is enclosed by back-quotes:
+
+\startbuffer
+`x^2`
+\stopbuffer
+
+\typebuffer
+
+But we rather stick to the \XML\ like coding:
+
+\startbuffer
+<am>x^2</am>
+\stopbuffer
+
+\typebuffer
+
+This is equivalent to the \TEX\ command:
+
+\asciimath{x^2}
+
+The interpretation of such a formula is no problem. But let's give a few examples
+where \ASCIIMATH\ lacks structure or needs a (sometimes bizar) interpretation to
+obtain adequate rendering:
+
+\noindentation Behaviour of superscripts and subscripts depends on operator that
+preceeds a number or variable:
+
+\starttabulate
+\FL
+\NC \type{`sin^-1(x)`}          \NC \asciimath{sin^-1(x)}             \NC \NR
+\NC \type{`sin^+1(x)`}          \NC \asciimath{sin^+1(x)}             \NC \NR
+\LL
+\stoptabulate
+
+\noindentation A script can be either one character or a number made from more
+characters:
+
+\starttabulate
+\FL
+\NC \type{`int_a^b f(x)`}       \NC \asciimath{int_a^b f(x)}          \NC \NR
+\NC \type{`int_aa^bb f(x)`}     \NC \asciimath{int_aa^bb f(x)}        \NC \NR
+\NC \type{`int_1000^2000 f(x)`} \NC \asciimath{int_1000^2000 f(x)}    \NC \NR
+\LL
+\stoptabulate
+
+\noindentation Behaviour of operator depends on character, where some characters
+have special meaning:
+
+\starttabulate
+\FL
+\NC \type{`d/dx`}               \NC \asciimath{d/dx}                  \NC \NR
+\NC \type{`q/qx`}               \NC \asciimath{q/qx}                  \NC \NR
+\LL
+\stoptabulate
+
+\noindentation Behaviour of the curly brackets is somewhat peculiar because at
+times they are not used for grouping anymore:
+
+\starttabulate
+\FL
+\NC \type{`{a/b}/{d/c}`}        \NC \asciimath{{a/b}/{d/c}}           \NC \NR
+\NC \type{`{a/b}//{d/c}`}       \NC \asciimath{{a/b}//{d/c}}          \NC \NR
+\LL
+\stoptabulate
+
+\noindentation Behaviour depends on sequence of scripts (solved in \CONTEXT):
+
+\starttabulate
+\FL
+\NC \type{`int_0^1 f(x)dx`}     \NC \asciimath{int_0^1 f(x)dx}        \NC \NR
+\NC \type{`int^1_0 f(x)dx`}     \NC \asciimath{int^1 text(_)0 f(x)dx} \NC \NR
+\LL
+\stoptabulate
+
+During the development of the \ASCIIMATH\ support we used the MathJax interpretor
+as a reference since that is available on the web. At the time of writing
+documentation was limited so some trial and error was involved in writing the
+parser. As usual we started from examples. Below we give a number of those
+examples so you can familiarize yourself with \ASCIIMATH. Note that you can use
+\TEX||like math coding and even use the backslash, but be warned for unexpected
+behaviour. In a webpage backticks are used to indicate \ASCIIMATH.

+One of the properties is that \TEX\ commands are supported, that is,. with a few

+confuse these symbols with the entities supported by \MATHML: in \ASCIIMATH\
+\type{circ} is circle and not a circumflex. Also, \type {&lt;}, \type {&gt;} are
+converted into \asciimath {&lt;} and \asciimath {&gt;} while \type {&amp;}
+becomes \asciimath{&amp;}. As usual with input formats that start out simple, in

+\startchapter[title={Unicode Math}]
+
+\startsection[title={entities}]
+
+Support for \MATHML\ showed up in \CONTEXT\ by the end of second millenium. The
+first more or less complete version of this manual dates from the end of 1999. At
+that time \UNICODE\ math was no fact yet and entities were the way to get special
+symbols done. Mapping the names of symbols onto something that could be rendered
+was up to the \XML\ processors and typesetting engine.
+
+Nowadays we can use \UNICODE\ directly although it has the drawback that not all
+editing applications show the corresponding shapes. It is for this reason that
+entities will have their use for a while. In the next table we see the official
+ones. The table is actually larger, but we only show the shapes that have a math
+property in the \CONTEXT\ character database. The full list is supported and can
+be found in the following documents:
+
+\starttyping
+http://www.w3.org/2003/entities/2007/w3centities-f.ent
+http://www.w3.org/2003/entities/2007/htmlmathml-f.ent
+\stoptyping
+
+\blank \showmathentities
+
+\stopsection
+
+\startsection[title={properties}]
+
+\noindentation A different way to look at this is \UNICODE\ itself. Here's the
+list of characters that have a math related property in \CONTEXT.
+
+\blank \showmathcharacters
+
+\stopsection
+
+\startsection[title={alphabets}]
+
+Traditionally (in \TEX) one enters \ASCII\ characters to represent identifiers
+and use a font switch to get for instance a bold rendering. In \UNICODE\ it is
+more natural to use code points that represent the meaning. So, instead if
+enterinf
+
+So instead of keying in byte \type {U+0058} for a bold \type {x} one will use an
+\UTF\ sequence representing \type {U+1D431}. Because there are not than many
+editors that show all those \UNICODE\ characters it still makes sense to use
+regular latin and greek alphabets combined with directives that tell what real
+alphabet is used. For \CONTEXT\ it does not matter what approach is chosen: both
+work ok and internally characters are mapped onto the right slot. When a font
+does not provide a shape a fallback is chosen. Technically one can construct a
+complete math font by combining all kind of fonts, but this is normally not
+needed.
+
+Here we show the combinations of styles and alternatives. Not all combinations
+are present in \UNICODE. Actually, as \UNICODE\ math is rather agnostic of
+cultural determined math rendering, at some point \CONTEXT\ could provide more.
+\footnote {An example is the German handwriting style Suetterlin that is still
+used for vectors.} Also, modern \OPENTYPE\ fonts can have alternatives, for
+instance variants of script, blackboard or fraktur. This is not related to
+\UNICODE\ and it makes no sense to encode that in \MATHML, but a setup of the
+rendering.
+
+\blank \showmathalphabets
+
+\stopsection
+
+\startsection[title={scripts}]
+
+Glyphs (traditionally) come in three sizes. The script and scriptscript sizes can
+be downscaled from text size but most math fonts have additional glyphs tuned for
+smaller sizes. The next table shows some of this.
+
+\blank \showmathscripts
+
+\stopsection
+
+\startsection[title={bold}]
+
+There are two ways to look at bold math. First there are bold alphabets and bold
+symbols and these have some meaning. Then there is what we can best call boldened
+math that is used in section titles and such. The normal bold then becomes heavy.
+The next table shows (for the font used here) what bold shapes are available.

+\chapter{Arabic}
+
+Let's start with admitting that I don't speak or read Arabic, and the sample
+texts used here are part of what we use in the Oriental \TEX\ project for
+exploring advanced Arabic typesetting. This chapter will not discuss arab
+typesetting in much detail, but should be seen as complementing the \quote
+{Onthology on Arabic Typesetting} written by Idris. Here I will only show what
+the consequences are of applying features. Because we see glyphs but often still
+deal with characters when analyzing what to do, we will use these terms mixed.
+
+The font that we use here is the \quote {arabtype} font by MicroSoft. This font
+covers Latin scripts and Arabic and has a rich set of features. It's also a rather
+big font, so it is a nice torture test for \LUATEX.
+
+First we show what \MKIV\ does with a sequence of characters when no features
+are enabled by the user. We have turn on color tracing. This gives us some
+feedback about the how the analyze worked out. Analyzing for Arabic boils down
+to marking the initial, mid, final and isolated forms. We don't need to
+explicitly enable analyzing, it's on by default. The \type {mode} flag is set
+to \type {node} because we cannot use \TEX's default mechanism. When \LUATEX\
+and \MKIV\ are beyond beta stage, we will use that mode by default.
+
+\ShowArabSample {arab-none}
+
+Once these forms are identified, the \type {init}, \type {medi}, \type {fina}
+and \type {isol} features can be applied since they need this information. As
+you can see, different shapes show up. The vowels (marks in \OPENTYPE\ speak)
+are not affected. It may not be entirely clear here, but these vowels don't have
+width.
+
+\ShowArabSample {arab-compose}
+
+We start with some preparations with regards to combinations of marks. This
+is really needed in order to get the right output.
+
+\ShowArabSample {arab-replace}
+
+The order in which features are applied is dictated by the font and users don't
+need to bother about it. In the next example we enable the \type {mark} and
+\type {mkmk} features. As with other positioning related features, these are
+normally applied late in the feature chain.
+
+\ShowArabSample {arab-mark}
+
+The \type {mark} feature positions marks (vowels) relative to characters, also
+known as mark to base. The \type {mkmk} feature positions marks to basemarks.
+
+\ShowArabSample {arab-mkmk}
+
+Kerning depends on the font. Some fonts don't need kerning, others may need
+extensive relative positioning of characters (by now glyphs).
+
+\ShowArabSample {arab-kern}
+
+So far we only had rather straightforward replacements. More sophisticated
+replacements are those driven by the context. In principle all replacements
+can be context driven, but the \type {calt} and \type {clig} features are
+normally dedicated to the real complex ones that take preceding and following
+characters into account.
+
+\ShowArabSample {arab-context}
+
+Ligatures are often used to beautify Arabic typeset documents. Here we enable the
+whole lot.
+
+\ShowArabSample {arab-ligs}
+
+Kerning deals with horizontal displacements, but \type {curs} (cursive) goes one
+step further. As with marks, positioning is based on anchor points and resolving
+them involves a bit of trickery because one needs to take into account that
+characters may have vowels attached to them.
+
+\ShowArabSample {arab-curs}
+
+One script can serve multiple languages so let's see what happens when we switch to
+Urdu.
+
+\ShowArabSample {arab-urdu}
+
+In practice one will enable most of the features. In \MKIV\ one can define feature
+sets as follows:
+
+\starttyping
+\definefontfeature
+  [arab-default]
+  [mode=node,language=dflt,script=arab,
+   init=yes,medi=yes,fina=yes,isol=yes,
+   liga=yes,dlig=yes,rlig=yes,clig=yes,
+   mark=yes,mkmk=yes,kern=yes,curs=yes]
+\stoptyping
+
+Applying these features to fonts can be done in several ways, with as most basic
+one:
+
+\starttyping
+\font\ArabFont=arabtype*arab-default at 18pt
+\stoptyping
+
+Normally one will do something like
+
+\starttyping
+\definefont[ArabFont][arabtype*arab-default at 18pt]
+\stoptyping
+
+or use typescripts to set up ap proper font collection, in which case we end
+up with definitions that look like:
+
+\starttyping
+\definefontsynonym[ArabType][name:arabtype][features=arab-default]
+\definefontsynonym[Serif][ArabType]
+\stoptyping
+
+More information about typescripts can be found in manuals and on the
+\CONTEXT\ wiki.
+
+We end this chapter with showing two arabic fonts so that you can get a taste
+if the differences: arabtype by MicroSoft and Palatino which is designed by
+Herman Zapf for Linotype.
+
+\def\ArabSampleFont{arabtype} \ShowArabSample {arab-default}
+
+\def\ArabSampleFont{name:palatinoltarabic} \ShowArabSample {arab-default}

+\chapter{Breaking apart}
+
+[todo: mention changes to hyphenchar etc]
+
+Because the long term objective is to have control over all aspects of the
+typesetting, quite some effort went into opening up one of the cornerstones
+of \TEX: breaking paragraphs into lines. And because this is closely related
+to hyphenating words, this effort also meant that we had to deal with ligature
+building and kerning.
+
+This is best explained with an example. Imagine that we have the following
+sentence  \footnote {The World Without Us, Alan Weisman; a quote from Richard
+Thomson in  chapter: Polymers are Forever.}
+
+\startnarrower \setupalign[nothyphenated]
+We imagined it was being ground down smaller and smaller, into a kind of
+powder. And we realized that smaller and smaller could lead to bigger and
+bigger problems.
+\stopnarrower
+
+With the current language settings for US English this can be hyphenated
+as follows:
+
+\startnarrower
+{\forgetall \hyphenatedpar{We imagined it was being ground down smaller and
+smaller, into a kind of powder. And we realized that smaller and smaller
+could lead to bigger and bigger problems.}}
+\stopnarrower
+
+So, when breaking a paragraph into lines, \TEX\ has a few options, but here
+actually not that many. If we permits two character snippets, we can get:
+
+\startnarrower \lefthyphenmin=2 \righthyphenmin=2
+{\forgetall \hyphenatedpar{We imagined it was being ground down smaller and
+smaller, into a kind of powder. And we realized that smaller and smaller
+could lead to bigger and bigger problems.}}
+\stopnarrower
+
+If we revert to UK English, we get:
+
+\startnarrower
+{\forgetall \uk \hyphenatedpar{We imagined it was being ground down smaller and
+smaller, into a kind of powder. And we realized that smaller and smaller
+could lead to bigger and bigger problems.}}
+\stopnarrower
+
+or, more tolerant,
+
+\startnarrower \lefthyphenmin=2 \righthyphenmin=2
+{\forgetall \uk \hyphenatedpar{We imagined it was being ground down smaller and
+smaller, into a kind of powder. And we realized that smaller and smaller
+could lead to bigger and bigger problems.}}
+\stopnarrower
+
+or with Dutch patterns:
+
+\startnarrower
+{\forgetall \nl \hyphenatedpar{We imagined it was being ground down smaller and
+smaller, into a kind of powder. And we realized that smaller and smaller
+could lead to bigger and bigger problems.}}
+\stopnarrower
+
+The code in traditional \TEX\ that deals with hyphenation and linebreaks is rather
+interwoven. There is a relationship between the font encoding and the way patterns
+are encodes. A few years after \TEX\ was written, support for multiple languages was
+added, which resulted in a mix of (kind of global) language settings (no nodes) and
+language nodes in the node lists. Traditionally it roughly works as follows:
+
+\startitemize
+
+\item The input \type {We imagined it} is tokenized and turned into glyph nodes. If
+non \ASCII\ characters are used (like pre composed accented characters) there may be
+a translation step: macros or active characters can insert \type {\char} commands or
+map onto other characters, for instance input byte 123 can become byte 198 which in
+turn ends up as a reference in a glyph node to a font slot. Whatever method is used to
+go from input to glyph node, eventually we have a reference to a position in a font.
+Unfortunately we had only 256 such slots per font.
+
+\item When it's time to break a paragraph into lines, traditional \TEX\ walks over
+the list, reconstruct words and inserts hyphenation points. In the process,
+inter|-|character kerns that are already injected need to be removed and reinserted,
+and ligatures have to be decomposed and recomposed. The magic of hyphenation is
+controlled by discretionary nodes. These specify what to do when a word is hyphenated.
+Take for instance the Dutch word \type {effe} which hyphenated becomes \type {ef-fe}
+so the \type {ff} either stays, or is split into \type {f-} and \type {f}.
+
+\item Because a glyph node is bound to a font, there is a relationship with the
+font encoding. Because there is no one 8-bit encoding that suits all languages, we
+may end up with several instances of a font in one document (used for different
+languages) and each when we switch language and|/|or font, we also have to enable
+a suitable set of patterns (in a matching encoding).
+
+\stopitemize
+
+You can imagine that this may lead to moderately complex mechanisms in macro packages.
+For instance, in \CONTEXT, to each language multiple font encodings can be bound and
+a switch of fonts (with related encoding) also results in a switch to a suitable set
+of patterns. But in \MKIV\ things are done different.
+
+First of all, we got rid of font encodings by exclusively using \UNICODE. We already
+were using \UTF\ encoded patterns (so that we could load them under different font
+encodings) so less patterns had to be loaded per language. That happened even before
+the \LUATEX\ development arrived at hyphenation.
+
+Before that effort started, Taco and I already played a bit with alternative
+hyphenation methods. For instance, we took large word lists with hyphenation points
+inserted. Taco wrote a loader (\LUA\ could not handle the large tables as function
+return value) and I made some hyphenation code in \LUA. Surprisingly we found out that
+it was pretty efficient, although we didn't  have the weighted hyphenation points
+that patterns may provide. Basically we simulated the \type {\hyphenation} command.
+
+While we went back to fonts, Taco's college Nanning wrote the first version of a new
+hyphenation storage mechanism, so when about half a year later we were ready to deal with the
+linebreak mechanisms, one of the key components was more or less ready. Where fonts forced me to
+write quite some \LUA\ code (still not finished), the new hyphenation
+mechanisms could be supported rather easy, if only because the framework was already
+kind of present (written during the experiments). Even better, when splitting the old
+code into \MKII\ and new \MKIV\ code, I could do most housekeeping in \LUA, and only
+needed a minimal amount of \TEX\ interfacing (partly redundant because of the shared
+interface). The new mechanism also was no longer bound to the format, which means
+that we could postpone loading of the patterns to runtime. Instead of the still
+supported traditional loading of patterns and exceptions, we load them under \LUA\
+control. This gave me yet another nice excercise in using \type {lpeg} (\LUA's string
+parser).
+
+With a new pattern loader in place, Taco started separating the hyphenation, ligature
+building and kerning. Each stage now has its own callback and each stage has an
+associated \LUA\ function, so that one can create a different order of execution or
+integrate it in other node parsing activities, most noticeably the handling of
+\OPENTYPE\ features.
+
+When I was trying to integrate this into the already existing node processing sequences,
+some nasty tricks were needed in order to feed the hyphenation function. At that
+moment it was still partly modelled after the traditional \TEX\ way, which boiled down
+to the following. As soon as the hyphenation function is invoked, it needs to know what
+the current language is. This information is not stored in the node list, only mid
+paragraph language switched are stored. Due to the fact that much information in \TEX\
+is global (well, in \LUATEX\ less and less) this complicates matters. Because in \MKIV\
+hyphenation, ligature building and kerning are done differently (dus to \OPENTYPE) we
+used the hyphenation callback to collect the language parameters so that we could use
+them when we called the hyphenation function later. This can definetely be qualified as
+an ugly hack.
+
+Before we discuss how this was solved, we summarize the state of affairs. In \LUATEX\
+we now have a sequence of callbacks related to paragraph building and in between not
+much happens any more.
+
+\startitemize[packed]
+\item hyphenation
+\item ligaturing
+\item kerning
+\item preparing linebreaking
+\item linebreaking
+\item finishing linebreaking
+\stopitemize
+
+Before we only had:
+
+\startitemize[packed]
+\item preparing linebreaking
+\stopitemize
+
+and this is where \MKIV\ hooks in ist code. The first three are disabled by
+associating them with dummy functions. I'm still not sure how the last two will
+fit it, especially because there is some interplay between \OPENTYPE\ features
+and linebreaking, like alternative glyphs at the end of the line. Because the
+\HZ\ and protruding mechanisms also will be supported we may as well end up with
+a mechanism for alternative glyphs built into the linebreak algorithm.
+
+Back to the current situation. What made matters even more complicated was the
+fact that we need to manipulate node lists while building horizontal material
+(hpacking) as well as for paragraphs (pre|-|linebreaking). Compare the following
+two situations. In the first case the hbox is packaged and hyphenation is not
+needed.
+
+\starttyping
+text \hbox {text} text
+\stoptyping
+
+However, when we unbox the content, hyphenation needs to be applied.
+
+\starttyping
+\setbox0=\hbox{text} text \unhbox0\ text
+\stoptyping
+
+[I need to check the next]
+
+Traditional \TEX\ does not look at all potential hyphenation points, but only around
+places that have a high probability as line|-|end. \LUATEX\ just hyphenates the whole
+list, although the function can be used selectively over a range, in \MKIV\ we see no
+reason for this and hyphenate whole lists.
+
+The new hyphenation routine not only operates on the whole list, but also can be made
+transparent for uppercase characters. Because we assume \UNICODE\ lowercase codes are
+no longer stored with the patterns (an \ETEX\ extension). The usual left- and
+righthyphenmin control is still there. The first word of a paragraph is no longer
+ignored in the process.
+
+Because the stages are separated now, the opportunity was there to separate between
+characters and glyphs. As with traditional \TEX, only characters are taken into
+account when hyphenating, so how do we distinguish between the two? The subtype (a
+property of each node) already registered if we were dealing with a ligature or not.
+Taco and Nanning had decided to treat the subtype as a bitset and after a bit of
+testing ans skyping we came to the conclusion that we needed an easy way to tag a
+glyph node as being \quote {already processed}. Keep in mind that as in the unhboxed
+example, the unhboxed content is already treated (hpack callback). If you wonder why
+we have these two moments of treatment think of this: if you put something in a box
+and want to know its dimensions, all font related features need to be applied. If the
+box is inserted as is, it can be recognized (a hlist or vlist node) and safely skipped
+in the prelinebreak handling. However, when it is unhboxed, we want to avoid
+reprocessing. Normally reprocessing will be prevented because the glyph nodes are
+mixed with kerns and ligatures are already built, but we can best play safe.
+Once we're done with processing a list (which can involve many passes, depending on
+what treatment is needed) we can tag the glyphs nodes as \quote {done} by adding 256
+to the subtype. We can then test on this property in callbacks while at the same time
+built-in functions like those responsible for hyphenation ignore this high bit.
+
+The transition from character to glyph is also done by changing bits in the subtype.
+At some point we need to set the subtype so that it reflects the node being a glyph,
+ligature or other special type (there are a few more types inherited from omega). I
+know that this all sounds complicated, but in \MKIV\ we now roughly do the following
+(of course this may and probably will change):
+
+\startitemize[packed]
+\item attribute driven manipulations (for instance case change)
+\item language driven manipulations (spell checking, hyphenation)
+\item font driven treatments, mostly features (ligature building, kerning)
+\item turn characters into glyphs (so that they will not be hyphenated again)
+\item normal ligaturing routine (currently still needed for not open type fonts, may
+      become obsolete)
+\item normal kerning routine (currently still needed for not open type fonts, may
+      become obsolete)
+\item attribute driven manipulations (special spacing and kerning)
+\stopitemize
+
+When no callbacks are used, turning characters into glyphs happens automatically behind
+the screens. When using callbacks (as in \MKIV) this needs to be done explicitly
+(but there is a helper function for this).
+
+So, by now \LUATEX\ can determine which glyph nodes play a role in hyphenation but still
+we have this \quote {what language are we in} problem. As usual in the development of
+\LUATEX, these fundamental changes took place in a setting where Taco and I are in a
+persistent state of Skyping, and it did not take much time to decide that in order to
+make the callbacks usable, it made much sense to moving the language related information
+to the glyph node as well, i.e.\ the number of the language object (patterns and
+exceptions), the left and right min values, and the boolean that tells how to treat
+uppercase characters. Each is now accessible in the usual way (by key). The penalty in
+additional memory is zero because it's stored along with the subtype bitset. By going this
+route, the ugly hack mentioned before could be removed as well.
+
+In the process of finalizing the code, discretionary nodes got a slightly different
+implementation. Originally they were organized as follows (ff is a ligature):
+
+\starttyping
+con-text == [c][o](pre=n-,post=,replace=1)[n][t][e][x][t]
+effe     == [e](pre=f-,post=f,replace=1)[ff][e]
+\stoptyping
+
+So, a discretionaty node contained information about what to put at the end of the broken
+line and what to put in front of the next line, as well as the number of following nodes
+in the list to skip when such a linebreak occured. Because this leads to rather messy code
+especially when ligatures are involved, so the decision was made to change the replacement
+counter into a node list holding those (optionally) to be replaced nodes.
+
+\starttyping
+con-text == [c][o](pre=n-,post=,replace=n)[t][e][x][t]
+effe     == [e](pre=f-,post=f,replace=ff)[e]
+\stoptyping
+
+This is much cleaner, but a consequence of this change was that all \MKIV\ node manipulation
+code written so far had to be reviewed.
+
+Of course we need to spend a few words on performance. We keep doing performance tests
+but currently we only remove bottlenecks that bother us. Later in the development
+optimization will tke place in the code. One reason is that the code changes, another
+reason is that large portions of \PASCAL\ code is turned  into \CCODE. Because
+integrating these changes (apart from preparations) took place within  a few weeks, we
+could reasonably well compare the old and the new hyphenation mechanisms using our
+(evolving) manuals and surprisingly the performance was certainly not worse than before.

+
+\subject{introduction}
+
+For a long time \TEX's way of coding math has dominated the
+typesetting world. However, this kind of coding is not that well
+suited for non academics, like schoolkids. Often kids do know how
+to key in math because they use advanced calculators. So, when a
+couple of years ago we were implementing a workflow where kids
+could fill in their math workbooks (with exercises) on||line, it
+made sense to support so called Texas Instruments math input.
+Because we had to parse the form data anyway, we could use a \type
+{[[} and \type {]]} as math delimiters instead of \type {$}. The
+conversion too place right after the form was received by the web
+server.

+
+By combining \LUA\ with \TEX, we can do the conversion from
+calculator math to \TEX\ immediately, without auxiliary programs
+or complex parsing using \TEX\ macros.
+
+\subject{tex}
+
+In a \CONTEXT\ source one can use the \type {\calcmath} command, as
+in:
+
+\starttyping
+The strange formula \calcmath {sqrt(sin^2(x)+cos^2(x))} boils
+down to ...
+\stoptyping
+
+One needs to load the module first, using:
+
+\starttyping
+\usemodule[calcmath]
+\stoptyping
+
+Because the amount of code involved is rather small, eventually we
+may decide to add this support to the \MKIV\ kernel.
+
+\subject{xml}
+
+Coding math in \TEX\ is rather efficient. In \XML\ one needs way
+more code. Presentation \MATHML\ provides a few basic constructs
+and boils down to combining those building blocks. Content \MATHML\
+is better, especially from the perspective of applications that
+need to do interpret the formulas. It permits for instance the
+\CONTEXT\ content \MATHML\ handler to adapt the rendering to
+cultural driven needs. The \OPENMATH\ way of coding is like
+content \MATHML, but more verbose with less tags. Calculator math
+is more restrictive than \TEX\ math and less verbose than any of
+the \XML\ variants. It looks like:
+
+\starttyping
+<icm>sqrt(sin^2(x)+cos^2(x))</icm> test
+\stoptyping
+
+And in display mode:
+
+\starttyping
+<dcm>sqrt(sin^2(x)+cos^2(x))</dcm> test
+\stoptyping
+
+\subject{speed}
+
+This script (which you can find in the \CONTEXT\ distribution as
+soon as the \MKIV\ code variants are added) is the first real
+\TEX\ related \LUA\ code that I wrote; so far I had only written
+some wrapping and spell checking code for the \SCITE\ editor. It
+also made a nice demo for a couple of talks that I held at
+usergroup meetings. The script has a lot of expressions. These
+convert one string into another. They are less powerful than
+regular expressions, but pretty fast and adequate. The feature I
+miss most is alternation like \type {(l|st)uck} but it's a small
+price to pay. As the \LUA\ manual explains: adding a \POSIX\
+compliant regexp parser would take more lines of code than \LUA\
+currently does.
+
+On my machine, running this first version took 3.5 seconds for 2500
+times typesetting the previously shown square root of sine and
+cosine. Of this, 2.1 seconds were spent on typesetting and 1.4 seconds
+on converting. After optimizing the code, 0.8 seconds were used for
+conversion. A stand alone \LUA\ takes .65 seconds, which includes loading
+the interpreter. On a test of 25.000 sample conversions, we could gain
+some 20\% conversion time using the \LUAJIT\ just in time compiler.

+{\em This aspect of \MKIV\ is under construction. We use non-realistic examples.
+We need to reimplement chinese numbering in \LUA, etc.\ etc.}
+
+{\em todo: There is no need for checkinf the width if the halfwidth feature is turned on.}
+
+\subject{introduction}
+
+In \CONTEXT\ \MKII\ we support \CJK\ languages. Intercharacter spacing as
+well as linebreaks are taken care of. Chinese numbering is dealt with and
+labels and other language specific aspects are supported too. The implementation
+uses active characters and some special encoding subsystem. Although it works
+quite okay, in \MKIV\ we follow a different route.
+
+The current implementation is an intermediate one and is used to explore the
+possibilities and identify needs. One handicap in implementing \CJK\ support is
+that the wishlist of features and behaviour is somewhat dependent on who you talk
+to. This means that the implementation will have some default behaviour but can be
+tuned to specific needs. The current implementation uses the script related
+analyser and is triggered by fonts but at some point I may decide to provide
+analysing independent of fonts.
+
+As will all things \TEX, we need to find a proper font to get our document typeset
+and because \CJK\ fonts are normally quite large they are not always available on
+your system by default.
+
+\subject{scripts and languages}
+
+I'm no expert on \CJK\ and will never be one so don't expect much insight in the
+scripts and languages here. Here we only look at the way a sequence of characters
+in the input turns into a typeset paragraph. For that it is important to keep in
+mind that in a Korean or Japanese text we might find Chinese characters and that
+the spacing rules become somewhat fuzzed by that. For instance Korean has spaces
+between words and words can be broken at any point, while Chinese has no spaces.
+
+Officially Chinese runs from top to bottom but here we focus on the horizontal
+variant. When turned into glyphs the characters normally are of equal width
+and in principle we could expect them all to be vertically aligned. However, a
+font can have characters that take half that space: so called halfwidth
+characters. And, of course, in practice a font might have shapes that fall into
+this categrory but happen to have their own width which deviates from this.
+
+This means that a mechanism that deals with \CJK\ has to take care of a few
+things:
+
+\startitemize[packed]
+\item Spaces at the end of the line (or actually anywhere in the input stream)
+      need to be removed but only for Chinese.
+\item Opening and closing symbols as well as punctuation needs special treatment
+      especially when they are halfwidth.
+\item Korean uses proportially spaces punctuation and mixes with other latin fonts,
+      while Chinese often uses built in latin shapes.
+\item We may break anywhere but not after an opening symbol like~( or and not
+      before a closing symbol like~).
+\item We need to deal with mixed Chinese and Korean spacing rules.
+\stopitemize
+
+Let's start with showing some Korean. We use one of the fonts shipped
+by Adobe as part of Acrobat but first we define a Korean featureset and
+a font.
+
+\startbuffer

+
+The Korean script reflect syllabes and is very structured.
+Although modern fonts contain prebuilt syllabes one can also use
+the jamo alphabet to build them from components. The following
+example is provided by Dohyun Kim:
+

+\chapter{User code}
+
+Previous versions of \LUATEX\ had multiple \LUA\ instances but in
+practice this was not that useful and therefore we decided to
+remove that feature and stick to one instance. One reason is that
+all activities take place in the zero instance anyway and other
+instance could not access variables defined there. Another reason
+was that every \type {\directlua} call is in fact a function call
+(and as such a closure) and \LUATEX\ catches errors nicely.
+
+The formal \type {\directlua} primitive originally can be called
+in two ways:
+
+\starttyping
+\directlua <instance> {lua code}
+\directlua name {some text} <instance> {lua code}
+\stoptyping
+
+The optional text is then part of the error message when one is
+issued. The new approach is that the number is used for the error
+message in case no \type {name} is specified. The exact string is
+set in \LUA. This means that in principle the command is backward
+compatible. Old usage will basically ignore the number and use
+the one and only instance, while new usage will use the number for
+an eventual message:
+
+\starttyping
+\directlua <message id> {lua code}
+\directlua name {some text} <message id> {lua code}
+\stoptyping
+
+In the second case the id is ignored. The advantage of the first
+call is that it saves tokens at the \TEX\ end and can be
+configured at the \LUA\ end. In \CONTEXT\ \MKIV\ we have adapted
+the code that invokes multiple instances by compatible code that
+provides a modest form of isolation. We don't want to enforce too
+many constraints, first of all because users will often use high
+level interfaces anyway, and also because we assume that users have
+no bad intentions.
+
+The main \LUA\ instance in \CONTEXT\ is accessible by: \footnote {Note
+2016: you can of course also use \type {context("lua")} here.}
+
+\startbuffer
+\startluacode
+global.tex.print("lua")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This gives: \quote {\getbuffer}.
+
+However, sometimes you don't want user code to interfere too much
+with the main code but still provide access to useful data. This
+is why we also provide:
+
+\startbuffer
+\startusercode
+global.tex.print("user 1")
+global.tex.print("user 2")
+if characters then
+    global.tex.print("access")
+else
+    global.tex.print("no access")
+end
+global.tex.print(global.characters.data[0xA9].contextname)
+\stopusercode
+\stopbuffer
+
+\typebuffer
+
+This gives: \quote {\getbuffer}.
+
+If you're writing a module, you might want to reserve a private
+namespace. This is done with:
+
+\startbuffer
+\definenamedlua[mymodule][my interesting module]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Now we can say:
+
+\startbuffer
+\startmymodulecode
+help = { "help" }
+global.tex.print(help[1])
+\stopmymodulecode
+\stopbuffer
+
+\typebuffer
+
+This gives: \quote {\getbuffer}. The information is remembered:
+
+\startbuffer
+\startmymodulecode
+global.tex.print(help[1])
+\stopmymodulecode
+\stopbuffer
+
+\typebuffer
+
+Indeed we get: \quote {\getbuffer}.
+
+Just to check the isolation we try:
+
+\startbuffer
+\startusercode
+global.tex.print(help and help[1] or "no help")
+\stopusercode
+\stopbuffer
+
+\typebuffer
+
+As expected this gives: \quote {\getbuffer} but when we do the
+following we will get an error message:
+
+\startbuffer
+\startusercode
+global.tex.print(help[1])
+\stopusercode
+\stopbuffer
+
+\typebuffer
+
+% {\batchmode \getbuffer} % somehow quits in context but not in texexec
+
+\starttyping
+! LuaTeX error <private user instance>:2: attempt to index global
+'help' (a nil value)
+stack traceback:
+	<private user instance>:2: in main chunk.
+<inserted text> ...userdata")
+global.tex.print(help[1])
+}
+\stoptyping
+
+An even more isolated variant is:
+
+\startbuffer
+\startisolatedcode
+help = { "help" }
+global.tex.print(help and help[1] or "no help")
+\stopisolatedcode
+\stopbuffer
+
+\typebuffer
+
+We get: \quote {\getbuffer}, while
+
+
+\startbuffer
+\startisolatedcode
+global.tex.print(help and help[1] or "no help")
+\stopisolatedcode
+\stopbuffer
+
+\typebuffer
+
+gives: \quote {\getbuffer}.
+
+You can get access to the global data of other named code blocks
+by using the \type {global} prefix. At that level you have also
+access to the instances, but this time we append \type {data}, so
+\type {user} has a table \type {userdata}:
+
+\startbuffer
+\startmymodulecode
+global.userdata.whatever = "be careful!"
+\stopmymodulecode
+\stopbuffer
+
+For convenience we have made \type {tex} as well as some \LUA\ tables
+directly accessible within an instance. However, we recommend not to
+extend these yourself (even if we do it in the core of \MKIV).
+
+% not yet ok:
+%
+% The next example is inspired by a question of Wolfgang Schuster who
+% wanted to write a module. Say that we have a file \type {demo.lua}:
+%
+% \starttyping
+% local demo = { }
+%
+% function demo.whow(str)
+%     global.tex.print("[" .. string.reverse(str) .. "]")
+% end
+%
+% return demo
+% \stoptyping
+%
+% The module can be \type {demo.tex}:
+%
+% \starttyping
+% \definenamedlua[demo][demo module example]
+%
+% \startdemocode
+% demo = global.require("demo.lua")
+% \stopdemocode
+%
+% \def\whow#1{\democode{demo.whow("#1"}}
+% \stoptyping
+%
+% We can now use this module:
+%
+% \starttyping
+% \usemodule[demo]
+% \whow{123}
+% \stoptyping

+\chapter{Colors redone}
+
+\subject{introduction}
+
+Color support has been present in \CONTEXT\ right from the start and
+support has been gradualy extended, for instance with transparency
+and spot colors. About 10 years later we have the first major rewrite
+of this mechanism using attributes as implemented in \LUATEX.
+
+Because I needed a test file to check if all things still work as
+expected, I decided to recap the most important commands in this
+chapter.
+
+\subject{color support}
+
+The core command is \type {\definecolor}, so let's define a few
+colors:
+
+\startbuffer
+\definecolor [red]     [r=1]
+\definecolor [green]   [g=1]
+\definecolor [blue]    [b=1]
+\definecolor [yellow]  [y=1]
+\definecolor [magenta] [m=1]
+\definecolor [cyan]    [c=1]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This gives us the following colors:
+
+\showcolorcomponents[red,green,blue,,yellow,magenta,cyan]
+
+As you can see in this table, transparency is part of a color
+specification, so let's define a few transparent colors:
+
+\startbuffer
+\definecolor [t-red]   [r=1,a=1,t=.5]
+\definecolor [t-green] [g=1,a=1,t=.5]
+\definecolor [t-blue]  [b=1,a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\showcolorcomponents[t-red,t-green,t-blue]
+
+Because transparency is now separated from color, we can define
+transparent behaviour as follows:
+
+\startbuffer
+\definecolor[half-transparent] [a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Implementing process color spaces was not that complex, but spot and multitone
+colors took a bit more code.
+
+\startbuffer
+\definecolor     [parentspot]               [r=.5,g=.2,b=.8]
+\definespotcolor [childspot-1] [parentspot] [p=.7]
+\definespotcolor [childspot-2] [parentspot] [p=.4]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The three colors, two of them are spot colors, show up as follows:
+
+\showcolorcomponents[parentspot,childspot-1,childspot-2]
+
+Multitone colors can also be defined:
+
+\startbuffer
+\definespotcolor [spotone]   [red]   [p=1]
+\definespotcolor [spottwo]   [green] [p=1]
+
+\definespotcolor [spotone-t] [red]   [a=1,t=.5]
+\definespotcolor [spottwo-t] [green] [a=1,t=.5]
+
+\definemultitonecolor
+    [whatever]
+    [spotone=.5,spottwo=.5]
+    [b=.5]
+\definemultitonecolor
+    [whatever-t]
+    [spotone=.5,spottwo=.5]
+    [b=.5]
+    [a=1,t=.5]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Transparencies don't carry over:
+
+\showcolorcomponents[spotone,spottwo,spotone-t,spottwo-t,whatever,whatever-t]
+
+Transparencies combine as follows:
+
+\startbuffer
+\blackrule[width=3cm,height=1cm,color=spotone-t]\hskip-1.5cm
+\blackrule[width=3cm,height=1cm,color=spotone-t]
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+We can still clone colors and overload color dynamically. I used the following
+test code for the \MKIV\ code:
+
+\startbuffer
+{\green green->red}
+\definecolor[green] [g=1]
+{\green green->green}
+\definecolor[green] [blue]
+{\green green->blue}
+\definecolor[blue] [red]
+{\green green->red}
+\setupcolors[expansion=yes]%
+\definecolor[blue] [red]
+\definecolor[green] [blue]
+\definecolor[blue] [r=1]
+{\green green->blue}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Of course palets and color groups are supported too. We seldom use
+colorgroups, but here is an example:
+
+\startbuffer
+\definecolorgroup
+  [redish]
+  [1.00:0.90:0.90,1.00:0.80:0.80,1.00:0.70:0.70,1.00:0.55:0.55,
+   1.00:0.40:0.40,1.00:0.25:0.25,1.00:0.15:0.15,0.90:0.00:0.00]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The redish color is called by number:
+
+\startbuffer
+\blackrule[width=3cm,height=1cm,depth=0pt,color=redish:1]\quad
+\blackrule[width=3cm,height=1cm,depth=0pt,color=redish:2]\quad
+\blackrule[width=3cm,height=1cm,depth=0pt,color=redish:3]
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+Palets work with names:
+
+\startbuffer
+\definepalet
+  [complement]
+  [red=cyan,green=magenta,blue=yellow]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This is used as:
+
+\startbuffer
+\blackrule[width=1cm,height=1cm,depth=0pt,color=red]\quad
+\blackrule[width=1cm,height=1cm,depth=0pt,color=green]\quad
+\blackrule[width=1cm,height=1cm,depth=0pt,color=blue]\quad
+\setuppalet[complement]%
+\blackrule[width=1cm,height=1cm,depth=0pt,color=red]\quad
+\blackrule[width=1cm,height=1cm,depth=0pt,color=green]\quad
+\blackrule[width=1cm,height=1cm,depth=0pt,color=blue]
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+% Rasters are still supported but normally one will use colors:
+%
+% \startbuffer
+% \raster[.5]{\blackrule[width=3cm,height=1cm]}\quad
+% \raster[.8]{\blackrule[width=3cm,height=1cm]}
+% \stopbuffer
+%
+% \typebuffer
+%
+% \startlinecorrection
+% \dontleavehmode\getbuffer
+% \stoplinecorrection
+
+Of course the real torture test is \METAPOST\ inclusion:
+
+\startbuffer
+\startMPcode
+    path p ; p := fullcircle scaled 4cm ;
+    fill p                  withcolor \MPcolor{spotone-t} ;
+    fill p shifted(2cm,0cm) withcolor \MPcolor{spottwo-t} ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+These transparent color circles up as:
+
+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+Multitone colors also work:
+
+\startbuffer
+\startMPcode
+    path p ; p := fullcircle scaled 2cm ;
+    fill p                  withcolor \MPcolor{spotone} ;
+    fill p shifted(2cm,0cm) withcolor \MPcolor{spottwo} ;
+    fill p shifted(4cm,0cm) withcolor \MPcolor{whatever} ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection
+\dontleavehmode\getbuffer
+\stoplinecorrection
+
+\subject{implementation}
+
+The implementation of colors using attributes if quite different
+from the traditional method. In \MKII\ color support works okay but
+the associated code is not that clean, if only because:
+
+\startitemize[packed]
+\item we need to keep track of grouped color usage
+\item and we do that using dedicated marks (using \TEX's mark mechanism)
+\item since this has limitations, we have quite some optimizations
+\item like local (no marks) and global colors (marks)
+\item and real dirty code to push and pop color states around pages
+\item and some messy code to deal with document colors
+\item and quite some conversion macros (think of \TEX\ not having floats)
+\stopitemize
+
+Although recent versions of \PDFTEX\ have a color stack mechanism, this
+is not adequate for our usage, if only because we support more colorspaces
+than this mechanism is supposed to deal with. (The color stack mechanism is
+written with a particular macro packag ein mind.)
+
+In \MKIV\ attributes behave like colors and therefore we no longer
+need to care about what happens at pageboundaries. Also, we no
+longer have to deal with the limitations of marks. Here:
+
+\startitemize[packed]
+\item we have distributed color spaces, color itself and transparency
+\item all injection of backend code is postponed to shipout time
+\item definition and conversion is delegated to \LUA
+\stopitemize
+
+Of course the current implementation is not as nice as we would like it
+to be. This because:
+
+\startitemize[packed]
+\item support mechanism are under construction
+\item we need to support both \MKII\ and \MKIV\ in one interface
+\item backend support is yet limited
+\stopitemize
+
+Although in principle a mechanism based on attributes is much faster than
+using marks cum suis, the new implementation is slower. The main reason is
+that we need to finalize the to be shipped out box. However, since this
+task involved more than just color, we will gain back some runtime when other
+mechanisms also use attributes.
+
+\subject{complications}
+
+This paragraph is somewhat complex, so skip it when you don't feel comfortable with
+the subject of when you've never seen low level \CONTEXT\ code.
+
+Attributes behave like fonts. This means that they are kind of frozen once
+material is boxed. Consider that we define a box as follows:
+
+\starttyping
+\setbox0\hbox{default {\red red \green green} default}
+\stoptyping
+
+What do you expect to come out the next code? In \MKII\ the \quote
+{default} inside the box will be colored yellow but the internal
+red and and green words will keep their color.
+
+\starttyping
+default {\yellow yellow \box0\ yellow} default
+\stoptyping
+
+When we use fonts switches we don't expect the content of the
+box to change. So, in the following the \quote {default} texts will
+{\em not} become bold.
+
+\starttyping
+\setbox0\hbox{default {\sl slanted \bi bold italic} default}
+default {\bf bold \box0\ bold} default
+\stoptyping
+
+Future versions of \LUATEX\ will provide more control over how attributes
+are applied to boxes, but for the moment we need to fallback on a solution
+built in \MKIV:
+
+\starttyping
+default {\yellow yellow \attributedbox0\ yellow} default
+\stoptyping
+
+There is also a \type {\attributedcopy} macro. These macros signal the
+attribute resolver (that kicks in just before shipout) that this box is to
+be treated special.
+
+In \MKII\ we had a similar situation which is why we had the option (only used
+deep down in \CONTEXT) to encapsulate a bunch of code with
+
+\starttyping
+\startregistercolor[foregroundcolor]
+some macro code ... here foregroundcolor is applied ... more code
+\stopregisteringcode
+\stoptyping
+
+This is for instance used in the \type {\framed} macro. First we package the content,
+foregroundcolor is not yet applied because the injected  specials of literals can interfere
+badly, but by registering the colors the nested color calls are tricked into thinking that
+preceding and following content is colored. When packaged, we apply backgrounds, frames,
+and foregroundcolor to the whole result. Because nested colors were aware of the
+foregroundcolor they have properly reverted to this color when needed.
+
+In \MKIV\ the situation is reversed. Here we definitely need to set the foregroundcolor
+because otherwise attributes are not set and here they don't interfere at all (no extra nodes).
+For this we use the same registration macros. When the lot is packaged, applying foregroundcolor
+is ineffective because the attributes are already applied. Instead of registering we could
+have flushed the framed content using \type {\attributedbox}, but this way we can keep the
+\MKII\ and \MKIV\ code base the same.
+
+To summarize, first the na\"ive approach. Here the nested colors know how to revert, but
+the color switch can interfere with the content (since color commands inject nodes).
+
+\starttyping
+\setbox\framed\vbox
+  {\color[foregroundcolor]{packaged framed content, can have color switches}}
+\stoptyping
+
+The \MKII\ approach registers the foreground color so the nested colors
+know what to do. There is no interfering code:
+
+\starttyping
+\startregistercolor[foregroundcolor]
+\setbox\framed
+\stopregisteringcode
+\setbox\framed{\color[foregroundcolor]{\box\framed}}
+\stoptyping
+
+The registration actually sets the color, so in fact the final coloring is not
+needed (does nothing). An alternative \MKIV\ approach is the following:
+
+\starttyping
+\color
+  [foregroundcolor]
+  {\setbox\framed{packaged framed content, can have color switches}}
+\stoptyping
+
+This works ok because attributes are applied to the whole content, i.e.\
+the box. In \MKII\ this would be quite ineffective and actually result
+in weird side effects.
+
+\starttyping
+< color stack is pushed and marks are set (unless local) >
+< color special or literal sets color to foregroundcolor >
+\setbox\framed{packaged framed content, can have color switches}
+< color special or literal sets color to foregroundcolor >
+< color stack is popped and marks are set (unless local) >
+\stoptyping
+
+So, effectively we set a box, and end up with:
+
+\starttyping
+< whatsits (special, literal and.or mark) >
+< whatsits (special, literal and.or mark) >
+\stoptyping
+
+in the main vertical lost and that will interfere badly with spacing
+and friends.
+
+In \MKIV\ however, a color switch, like a font switch does not leave any
+traces, it just sets a state. Anyway, keep in mind that there are some
+rather fundamental conceptual differences between the two appoaches.
+
+Let's end with an example that demonstrates the problem. We fill two boxes:
+
+% in previous examples we may have messed up colors
+
+\definecolor[red]   [darkred]
+\definecolor[green] [darkgreen]
+\definecolor[blue]  [darkblue]
+\definecolor[yellow][darkyellow]
+
+\startbuffer
+\setbox0\hbox{RED {\blue blue} RED}
+\setbox2\hbox{RED {\blue blue} {\attributedcopy0} RED}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We will flush these in the following lines:
+
+\startbuffer
+{unset \color[red]{red \CopyMe} unset
+    \color[red]{red \hbox{red \CopyMe}} unset}
+{unset \color[red]{red \CopyMe} unset
+    {\red red \hbox{red \CopyMe}} unset}
+{unset \color[red]{red \CopyMe} unset
+    {\red red \setbox0\hbox{red \CopyMe}\box0} unset}
+{unset \color[red]{red \CopyMe} unset
+    {\hbox{\red red \CopyMe}} unset}
+{\blue blue \color[red]{red \CopyMe} blue
+    \color[red]{red \hbox{red \CopyMe}} blue}
+\stopbuffer
+
+\typebuffer
+
+\startbuffer[yes]
+\def\CopyMe{\attributedcopy2\ \copy4}
+\stopbuffer
+
+\startbuffer[no]
+\def\CopyMe{\copy2\ \copy4}
+\stopbuffer
+
+First we define \type {\CopyMe} as follows:
+
+\typebuffer[yes]
+
+This gives:
+
+\start \enableattributeinheritance \getbuffer[yes] \getbuffer \stop
+
+Compare this with:
+
+\typebuffer[no]
+
+This gives:
+
+\getbuffer[no] \getbuffer
+
+You get the picture? At least in early version of \MKIV\ you need to
+enable support for inheritance with:
+
+\starttyping
+\enableattributeinheritance
+\stoptyping

+\chapter {Dirty tricks}
+
+If you ever laid your hands on the \TeX book, the words \quote {dirty tricks} will
+forever be associated with an appendix of that book. There is no doubt that you need
+to know a bit of the internals of \TEX\ in order to master this kind of trickyness.
+
+In this chaper I will show a few dirty \LUATEX\ tricks. It also gives an impression
+of what kind of discussions Taco and I had when discussing what kind of support should
+be build in the interface.
+
+\subject{afterlua}
+
+When we look at \LUA\ from the \TEX\ end, we can do things like:
+
+\startbuffer
+\def\test#1{%
+    \setbox0=\hbox{\directlua0{tex.sprint(math.pi*#1)}}%
+    pi: \the\wd0\space\the\ht0\space\the\dp0\par
+}
+\stopbuffer
+
+\typebuffer \blank \getbuffer \blank
+
+But what if we are at the \LUA\ end and want to let \TEX\ handle things?  Imagine
+the following call:
+
+\startbuffer
+\setbox0\hbox{} \dimen0=0pt \ctxlua {
+    tex.sprint("\string\\setbox0=\string\\hbox{123}")
+    tex.sprint("\string\\the\string\\wd0")
+}
+\stopbuffer
+
+\typebuffer
+
+This gives: \ignorespaces \getbuffer. This may give you the impression that \TEX\
+kicks in immediately, but the following example demonstrates otherwise:
+
+\startbuffer
+\setbox0\hbox{} \dimen0=0pt \ctxlua {
+    tex.sprint("\string\\setbox0=\string\\hbox{123}")
+    tex.dimen[0] = tex.box[0].width
+    tex.sprint("\string\\the\string\\dimen0")
+}
+\stopbuffer
+
+\typebuffer
+
+This gives: \getbuffer. When still in \LUA, we never get to see the width
+of the box.
+
+A way out of this is the following rather straightforward approach:
+
+\starttyping
+function test(n)
+    function follow_up()
+        tex.sprint(tex.box[0].width)
+    end
+    tex.sprint("\\setbox0=\\hbox{123}\\directlua 0 {follow_up()}")
+end
+\stoptyping
+
+We can provide a more convenient solution for this:
+
+\starttyping
+after_lua = { } -- could also be done with closures
+
+function the_afterlua(...)
+    for _, fun in ipairs(after_lua) do
+        fun(...)
+    end
+    after_lua = { }
+end
+
+function afterlua(f)
+    after_lua[#after_lua+1] = f
+end
+
+function theafterlua(...)
+    tex.sprint("\\directlua 0 {the_afterlua("
+        .. table.concat({...},',') .. ")}")
+end
+\stoptyping
+
+If you look closely, you will see that we can (optionally) pass arguments
+to the function \type {theafterlua}. Usage now becomes:
+
+\starttyping
+function test(n)
+    afterlua(function(...)
+        tex.sprint(string.format("pi: %s %s %s\\par",...     ))
+    end)
+    afterlua(function(wd,ht,dp)
+        tex.sprint(string.format("ip: %s %s %s\\par",dp,ht,wd))
+    end)
+    tex.sprint(string.format("\\setbox0=\\hbox{%s}",math.pi*n))
+    local box_0 = tex.box[0]
+    theafterlua(box_0.width,box_0.height,box_0.depth)
+end
+\stoptyping
+
+The last call may confuse you but since it does a print to \TEX, it is
+in fact a delayed action. A cleaner implementation is the following:
+
+\starttyping
+local delayed = { }
+
+local function flushdelayed(...)
+    delayed = { }
+    for i=1, #t do
+        t[i](...)
+    end
+end
+
+function lua.delay(f)
+    delayed[#delayed+1] = f
+end
+
+function lua.flush(...)
+    tex.sprint("\\directlua{flushdelayed(" ..
+        table.concat({...},',') .. ")}")
+end
+\stoptyping
+
+Usage is similar:
+
+\starttyping
+function test(n)
+    lua.delay(function(...)
+        tex.sprint(string.format("pi: %s %s %s\\par",...))
+    end)
+    tex.sprint(string.format("\\setbox0=\\hbox{%s}",math.pi*n))
+    local box_0 = tex.box[0]
+    lua.flush(box_0.width,box_0.height,box_0.depth)
+end
+\stoptyping
+

+\chapter {Virtual Reality}
+
+When a font lacks glyphs we can add new ones by making the font
+virtual. A virtual font has virtual glyphs: instead of a reference
+to a slot in the current font, such a glyph refers to a slot in
+another font, or it combines several glyphs into one, or it just
+contains code that ends up in the result (for instance a sequence
+of \PDF\ commands that describes the shape). For \TEX\ a character
+and its dimensions are what matters and what ends up in the result
+is mostly a matter for the backend. In \LUATEX\ the backend is
+integrated but even then during the typesetting process only the
+characteristics of a glyph are used and not the shape.
+
+In \CONTEXT\ we have a feature called \quote {compose} which
+extends the font with extra characters and constructs its
+representation from those of other characters.
+
+\starttyping
+\definefontfeature
+  [composes]
+  [kern=yes,ligatures=yes,compose=yes]
+\stoptyping
+
+When this feature is applied, \CONTEXT\ will try to fill in the
+gaps in the \UNICODE\ vector of the font based on for instance
+(de)composition information. Of course this has some limitations.
+For instance \OPENTYPE\ fonts can ships with features, like
+smallcaps. Currently we ignore this property when we add composed
+characters. Technically it is no big deal to add variants but we
+simply didn't do it yet at the time of this writing. After all,
+such fallbacks can best be avoided by using proper fonts.
+
+Our \CONTEXT\ \MKIV\ wishlist mentions a mechanism for combining
+fonts into one font. For this we can use virtual fonts and the
+machinery for that is in available in \LUA\ code. However such a
+mechanism will be used for more drastic completion of a font than
+the compose feature. For instance, often Chinese fonts lack proper
+Latin glyphs and vise versa. But when we combine such fonts we
+really do want to keep \OPENTYPE\ features working and so we
+cannot use virtual fonts (unless we start merging features which
+can become really messy and runtime consuming).
+
+There is a relative simple solution using real fonts that kind of
+behave like virtual ones: virtual real fonts. The trick is in the
+fact that \TEX\ permits access to characters not present in the
+font. Say that we have
+
+\starttyping
+<char 123><char 124><char 125>
+\stoptyping
+
+and that slot~124 has no glyph. In that case \TEX\ just inserts a
+glyph node with a reference to the current font and this
+character. Of course, when we let \TEX\ carry on, at some point it
+will need glyph properties like the width, height and/or depth.
+And in the backend, when writing the result to file, \TEX\ wants
+to insert the glyph data in the file. In both cases we end up with
+a message in the log file and a result file with missing data.
+
+In \CONTEXT\ \MKIV\ we intercept the node lists at several points
+and one of those is directly after the construction. So let's
+consider the previous example again.
+
+\starttyping
+<font 32 char 123><font 32 char 124><font 32 char 125>
+\stoptyping
+
+Because the font has no character 124 we need a way to substitute
+it with another character. All we have to do is to change the font
+identifier~32 into one that makes sense. Such a replacement loop
+is kind of trivial.
+
+\starttyping
+for n in traverse_id(glyph,head) do
+    local v = vectors[n.font]
+    if v then
+        local id = v[n.char]
+        if id then
+            n.font = id
+        end
+    end
+end
+\stoptyping
+
+We have a table (\type{vectors}) that can have a subtable (\type
+{v}) for font with id (\type {n.font}) in which there can be a
+reference from the current character (\type {n.char}) to another
+font (\type {id}) that we use to replace the font reference (\type
+{n.font}).
+
+Filling the table is relatively easy but an explanation is beyond
+this chapter. We only show the high level interface, one that
+certainly will evolve.
+
+\starttyping
+\definefontfallback
+  [SerifFallback]
+  [Mono]
+  [0x000-0x3FF]
+  [check=yes,force=no]
+\stoptyping
+
+This command registers an entry in the \type {SerifFallback}
+namespace. There can be multiple replacement in row (by just using
+more of these commands), but here we have only one. The range
+0x000--0x3FF will be checked and if the main font lacks a glyph in
+that range, it will be taken from the font with the symbolic name
+\type {Mono}. That name will be resolved when the fallback is
+associated with a font. The \type {check} option tells the
+machinery that we need to check for existence and because we don't
+\type {force}, we will only replace missing glyphs. There is also
+an \type {rscale} option, that permits relative scaling of the
+fallback font to the main font, something that may be needed when
+fonts come from different sources.
+
+\starttyping
+\definefontsynonym
+  [SerifPlus]
+  [Serif]
+  [fallbacks=SerifFallback]
+\stoptyping
+
+This command associates a fallback with a font. There is always a
+parent font and that is the font that triggers the checking of the
+node list.
+
+\starttyping
+\definefont [MySerif] [SerifPlus at 10pt]
+\stoptyping
+
+Here we defines a font called \type {\MySerif} that refers to a
+symbolic name \type {SerifPlus} which in turn refers to the
+current \type {Serif} font (these symbolic names are resolved in
+typescripts, one of the building blocks of \CONTEXT s font
+system). The mentioned fallbacks will be initialized when the font
+is defined. This examples demonstrates that there is a clean
+separation between font definitions and fallbacks. This makes it
+possible to share fallback definitions.
+
+So, let's summarize what happens:
+
+\startitemize[packed]
+\item a font is defined in the normal way but has falbacks
+\item the associated fallback fonts are defined too
+\item the main font gets a table with fallback id's
+\item the main font is used in the document stream
+\item the node list is intercepted and parsed for this font
+\item references to fallback fonts take care of missing glyphs
+\stopitemize
+
+We end with an example.
+
+\startbuffer
+\definefontfallback [Demo] [Mono] [0x30-0x39] [force=yes]
+\definefontsynonym  [DemoSerif] [Serif] [fallbacks=Demo]
+
+\definefont [MyDemoSerif] [DemoSerif at 20pt]
+
+\MyDemoSerif Here the digits, like 13579, are replaced.
+\stopbuffer
+
+\typebuffer
+
+\start \blank[3*medium] \getbuffer \blank[3*medium] \stop
+
+Beware: the fallback definitions are global, but this is hardly a
+problem because normal such trickery is taking place at the document
+level.

+\chapter{A fresh look at fonts}
+
+\subject{readers}
+
+Now that we have the file system, \LUA\ script integration, input
+encoding and basic logging in place, we have arrived at fonts.
+Although today \OPENTYPE\ fonts are the fashion, we still need to
+deal with \TEX's native font machinery. Although Latin Modern and
+the \TEX\ Gyre collection will bring us many free \OPENTYPE\
+fonts, we can be sure that for a long time \TYPEONE\ variants will
+be used as well, and when one has lots of bought fonts, replacing
+them with \OPENTYPE\ updates is not always an option. And so,
+reimplementing the readers for \TEX\ Font Metrics (\type {tfm}
+files) and Virtual Fonts (\type {vf} files), was the first step.
+
+Because \ALEPH\ font handling was integrated already, Taco decided
+to combine the \TFM\ and \OFM\ readers into a new one. The
+combined loader is written in C and produces tables that are
+accessible from within \LUA. A problem is that once a font is
+used, one cannot simply change its metrics. So, we have to make
+sure that we apply changes before a font is actually used:
+
+\starttyping
+\font\test=texnansi-lmr at 31.415 pt
+\test Yet another nice Kate Bush song: Pi
+\stoptyping
+
+In this example, any change to the fontmetrics has to be done before
+\type {test} is invoked. For this purpose the \type {define_font}
+callback is provided. Below you see an experimental overload:
+
+\starttyping
+callback.register("define_font", function (name,area,size)
+    return fonts.patches.process(font.read_tfm(name,size))
+end )
+\stoptyping
+
+The \type {fonts.patched.process} function (currently in \CONTEXT\
+\MKIV) implements a mechanism for tweaking the font parameters in
+between. In order to get an idea of further features we played a
+bit with ligature replacement, character spacing, kern tweaking
+etc. Think of such a function (or a chain of functions) doing
+things similar to:
+
+\starttyping
+callback.register("define_font", function (name,area,size)
+    local tfmblob = font.read_tfm(name,size) -- build in loader
+    tfmblob.characters[string.byte("f")].ligatures = nil
+    return tfmblob -- datastructure that TeX will use internally
+end )
+\stoptyping
+
+Of course the above definition is not complete, if only because we
+need to handle chained ligatures as well (fl followed by i).
+
+In practice we prefer a more abstract interface (at the macro
+level) but the idea stays the same. Interesting is that having
+access to the internals this way already makes our \TEX\ Live more
+interesting. (We cannot demonstrate this trickery here because
+when this document is processed you cannot be sure if the
+experimental interface is still in place.)
+
+When playing with this we ran into problems with file searching.
+When performing the backend role, \LUATEX\ will look in the \TEX\
+tree if there is a corresponding virtual file. It took a while and
+a bit of tracing (which is not that hard in the \LUA\ based
+reader) to figure out that the omega related path definitions in
+\type {texmf.cnf} files were not correct, something that went
+unnoticed because omega never had a backend integrated and the
+\DVI\ processors did multiple searches to get around this.
+
+Currently, if you want to enable extensive tracing of file
+searching and loading, you can set an environment variable:
+
+\starttyping
+MTX.INPUT.TRACE=3
+\stoptyping
+
+This will produce a lot of information about what file is asked
+for, what types (tex, font, etc) determines the search, along what
+paths is being searched, what readers and locators are used (file,
+zip, protocol), etc.
+
+\subject{AFM}
+
+While Taco implemented the virtual font reader |<|eventually its
+data will be merged with the \TFM\ table|>| I started playing with
+constructing \TFM\ tables directly. Because \CONTEXT\ has a rather
+systematic naming scheme, we can rather easily see which encoding
+we are dealing with. This means that in principle we can throw all
+encoded \TFM\ files out of our tree and construct the tables using
+the \AFM\ file and an encoding vector.
+
+It took us a good day to figure out the details, but in the end we
+were able to trick \LUATEX\ into using \AFM\ files. With a bit of
+internal caching it was even reasonable fast. When the basic
+conversion mechanism was written we tried to compare the results
+with existing \TFM\ metrics as generated by \type {afm2tfm} and
+\type {afm2pl}. Doing so was less trivial than we first thought.
+To mention a few aspects:
+
+\startitemize[packed]
+\item heights and depths have a limited number of values in \TEX
+\item we need to convert to \TEX's scaled points
+\item rounding errors of one scaled point occur
+\item \type {afm2tfm} can only add kerns when virtual fonts are used
+\item \type {afm2tfm} adds some extra ligatures and also does some
+      kern magic
+\item \type {afm2pl} adds even more kerns
+\item the tools remove kern pars between digits
+\stopitemize
+
+In this perspective we need not be too picky on what exactly a
+ligature is. An example of a ligature is \type {fi} and such a
+character can be in the font. In the \TFM\ file, the definition of
+\type {f} contains information about what to do when it's followed
+by an \type {i}: it has to insert a reference (character number)
+pointing to the fi glyph.
+
+However, because \TEX\ was written in \ASCII\ time space, there
+was a problem of how to get access to for instance the Spanish
+quotation and exclamation marks. Here the ligature mechanism
+available in the \TFM\ format was misused in the sense that a
+combination of \type {exclam} and \type {quoteleft} becomes \type
+{exclamdown}. In a similar fashion will two single quotes become a
+double quote. And every \TEX ie knows that multiple hyphens
+combine into -- (endash) and --- (emdash), where the later one is
+achieved by defining a ligature between an endash and a hyphen.
+
+Of course we have to deal with conversions from \AFM\ units (1000
+per em) to \TEX's scaled points. Such conversions may be sensitive
+for rounding errors. Because we noticed differences of one scaled
+point, I tried several strategies to get the results consistent
+but so far I didn't manage to find out where these differences
+come from. Rounding errors seem to be rather random and I have no
+clue what strategy the regular converters follow. Another fuzzy
+area are the font parameters (visible as font dimensions for
+users): I wonder how many users really know what values are used
+and why.
+
+You may wonder to what extend this rounding problem will influence
+consistent typesetting. We have no reason to assume that the
+rounding error is operating system dependent. This leaves the
+different methods used and personally I have no problems with the
+direct reader being not 100\% compatible with the regular tools.
+First of all it's an illusion to think that \TEX\ distributions
+are stable over the years. Fonts and conversion tools are being
+updated every now and then, and metrics change over time (apart
+from Computer Modern which is stable by definition). Also, pattern
+file are updated, so paragraphs may be broken into lines different
+anyway. If you really want stability, then you need to store the
+fonts and patterns with your document.
+
+As we already mentioned, the regular converter programs add kerns
+as well. Treating common glyph shapes similar is not uncommon in
+\CONTEXT\ so I decided to provide methods for adding \quote
+{missing} kerns. For example, with regards to kerning, we can
+treat \type {eacute} the same way as an~\type {e}. Some ligatures,
+like \type {ae} or \type {fi}, need to be seen from two sides:
+when looked at from the left side they resemble an \type {a} and
+\type {f}, but when kerned at their right, they are to be treated
+as \type {e} and \type {i}.
+
+So, when all this is taken care of, we will have a reasonable
+robust and compatible way to deal with \AFM\ files and when this
+variant is enabled, we can prune our \TEX\ trees pretty well.
+Also, now that we have font related tables, we can start moving
+tables built out of \TEX\ macros (think of protruding and hz) to
+\LUA, which will not only save us much hash entries but also
+permits us faster implementations.
+
+The question may arise why there is no hard coded \AFM\ reader.
+Although some speed up can be achieved by reading the table with
+\AFM\ data directly, there would still be the issue of making that
+table accessible for manipulations as described (costs time too).
+The \AFM\ format is human readable contrary to the \TFM\ format
+and therefore they can conveniently be processed by \LUA. Also,
+the possible manipulations may differ per macro package, user, and
+even documents. The changes of users and developers reaching an
+agreement about such issues is near zero. By writing the reader in
+\LUA, a macro package writer can also implement caching mechanisms
+that suits the package. Also, keep in mind that we often only need
+to load about four \AFM\ files or a few more when we mix fonts.
+
+In my main tree (regular distributions) there are some 350 files
+in \type {texnansi} encoding that take over 2~MByte. My personal
+font tree has over a thousand such entries which means that we can
+prune the tree considerably when we use the \AFM\ loader. Why
+bother about \TFM\ when \AFM\ can do the job.
+
+In order to reduce the overhead in reading the \AFM\ file, we now
+use external caching, which (in \CONTEXT\ \MKIV) boils down to
+serializing the internal \AFM\ tables and compiling them to
+bytecode. As a result, the runtime becomes comparable to a run
+using regular \TFM\ files. On this document usign the \AFM\ reader
+(cached) takes some .3 seconds more on 8 seconds total (28 pages
+in Optima Nova with a couple of graphics).
+
+While we were playing with this, Hermann Zapf surprised me by
+sending me a \CD\ with his marvelous new Palatino Sans. So,
+instead of generating \TFM\ metrics, I decided to use \type
+{ttf2afm} to generate me an \AFM\ file from the \TRUETYPE\ files
+and use these metrics. It worked right out of the box which means
+that one can copy a set of font files directly from the source to
+the tree. In a demo document the Palatino Sans came out quite well
+and so we will use this font to explore the upcoming Open Type
+features.
+
+Because we now have less font resources (only two files per font)
+we decided to get away from the spread||all||over||the||tree
+paradigm. For this we introduced
+
+\starttyping
+../fonts/data/vendor/collection
+\stoptyping
+
+like:
+
+\starttyping
+../fonts/data/tex/latin-modern
+../fonts/data/tex-gyre/bonum
+../fonts/data/linotype/optima-nova
+../fonts/data/linotype/palatino-nova
+../fonts/data/linotype/palatino-sans
+\stoptyping
+
+Of course one needs to adapt the related font paths in the
+configuration files but getting that done in tex distributions is
+another story.
+
+\subject{map files}
+
+Reading an \AFM\ file is only part of the game. Because we bypass
+the regular \TFM\ reader we may internally end up with different
+names of fonts (and|/|or files). This also means that the map
+files that map an internal name onto an font (outline) file may be
+of no use. The map file also specifies the encoding file which
+maps character numbers onto names used in font files.
+
+The map file maps a font name to a (preferable outline) font
+resource file. This can be a file with suffix \type {pfb}, \type
+{ttf}, \type {otf} or alike. When we convert am \AFM\ file into a
+more suitable format, we also store the associated (outline)
+filename, that we use later when we assemble the map line data (we
+use \type {\pdfmapline} to tell \LUATEX\ how to prepare and embed
+a file.
+
+Eventually \LUATEX\ will take care of all these issues itself
+thereby rendering map files and encoding files kind of useless.
+When loading an \AFM\ file we already have to read encoding files,
+so we have all the information available that normally goes into
+the map file. While conducting experiments with reading \AFM\
+files, we therefore could use the \type {\pdfmapline} primitive to
+push the right entries into font inclusion machinery. Because
+\CONTEXT\ already handles map data itself we could easily hook
+this into the normal handlers for that. (There are some nasty
+synchronization issues involved in handling map entries in general
+but we will not bother you with that now).
+
+Although eventually we may get rid of map files, we also used the
+general map file handling in \CONTEXT\ as a playground for the
+\XML\ handler that we wrote in \LUA. Playing with many map files
+(a few KBytes) coded in \XML\ format, or with one big map file
+(easily 800 MBytes) makes a good test case for loading and dumping
+
+But why bother too much about map files in \LUATEX\ \unknown\ they
+will go away anyway.
+
+\subject{OTF \& TTF}
+
+One of the reasons for starting the \LUATEX\ development was that we wanted to
+be able to use \OPENTYPE\ (and \TRUETYPE) fonts in \PDFTEX. As a prelude (and kind of
+transition) we first dealt with \TYPEONE\ using either \TFM\ or \AFM. For \TEX\ it does
+not really matter what font is used, it only deals with dimensions and generic
+characteristics. Of course, when fonts offer more advanced possibilities, we may
+need more features in the \TEX\ kernel, but think of \HZ\ or protruding as provided
+by \PDFTEX: it's not part of the font (specification) but of the engine. The same
+is actually true for kerning and ligature building, although here the font (data) may
+provide the information needed to deal with it properly.
+
+\OPENTYPE\ fonts come with features. Examples of features are using oldstyle figures or
+tabular digits instead of the default ones. Dealing with such issues boils down to
+replacing one character representation by another or treating combinations of character
+in the input differently depending on the circumstances. There can be relationships
+between languages and scripts, but, as \TEX ies know, other relationships exist as well,
+for instance between content and visualization.
+
+Therefore, it will be no surprise that \LUATEX\ does not simply implement the \OPENTYPE\
+specification as such. On the one hand it implements a way to load information stored
+in the font, on the other hand it implements mechanisms to fullfil the demands of such
+fonts and more. The glue between both is done with \LUA. In the simple case of ligatures
+and kerns this goes as follows. A user (or macropackage) specified a font, and this
+call can be intercepted using a callback. This callback can use a built in function that
+loads an \OTF\ or \TTF\ font. From this table, a font table is constructed that is passed
+on to \TEX. The construction
+may involve building ligature and kerning tables using the information present
+in the font file, but it may as well mean more. So, given a bare \LUATEX\ system,
+\OPENTYPE\ font support is not giving you automatically handling of features, or more
+precisely, there is no hard coded support for features.
+
+This may sound as a disadvantage
+but as soon as you start looking at how \TEX\ users use their system (in most cases
+by using a macro package) you may understand that flexibility is larger this way. Instead
+of adding more and more control and exceptions, and thereby making the kernel more
+instable and complex, we delegate control to the macro package. The advantage is that
+there are no (everlasting) discussions on how to deal with things and in the end the
+user will use a high level interface anyway. Of course the macro package needs proper
+access to the font's internals, but this is provided: the code used for reading in the
+data comes from FontForge (an advanced font editor) and is presented via \LUA\ tables
+in a well organized way.
+
+Given that users expect \OPENTYPE\ features to be supported, how do we provide an
+interface. In \CONTEXT\ the user interface has always be an important aspect and
+consistency is a priority. On the other hand, there has been the tradition of specifying
+the size explicity and a new custom introduced by \XETEX\ to enhance fontname
+with directives. Traditional \TEX\ provides:
+
+\starttyping
+\font \name filename [optional size]
+\stoptyping
+
+\XETEX\ accepts
+
+\starttyping
+\font \name "fontname[:optional features]" [optional size]
+\font \name  fontname[:optional features]  [optional size]
+\stoptyping
+
+Instead of a fontname one can pass a filename between square brackets. \LUATEX\
+handles:
+
+\starttyping
+\font \name  anything  [optional size]
+\font \name {anything} [optional size]
+\stoptyping
+
+where anything as well as the size are passed on to the callback.
+
+This permits us to implement a traditional specification, support \XETEX\ like
+definitions, and easily pass information from a macro package down to the
+callback as well. Interpreting anything is done in \LUA.
+
+While implementing the \LUA\ side of the loader we took a similar approach
+as the \AFM\ reader and cached intermediate tables as well as keep track
+of font names (in addition to filenames). In order to be able to quickly
+determine the (internal) font name of an \OPENTYPE\ font, special loader
+functions are provided.
+
+The size is kind of special, because we can have specifications like
+
+\starttyping
+at 10pt
+at 3ex
+at \dimexpr\bodyfontsize+1pt\relax
+\stoptyping
+
+This means that we need to handle that on the \TEX\ side and pass the
+calculated value to the callback.
+
+Virtual fonts have a rather special nature. They permit you to define variations
+of fonts using other fonts and special (\DVI\ related) operators. However, from the
+perspective of \TEX\ itself they don't exist at all. When you create a virtual font
+you also end up with a \TFM\ file and \TEX\ only needs this file, which defined
+characters in terms of a width, height, depth and italic correction as well as
+associates characters with kerning pairs and ligatures. \TEX\ leaves it to the
+backend to deal the actual glyphs and therefore the backend will be confronted
+by the internals of a virtual font. Because \PDFTEX\ and therefore \LUATEX\ has the
+backend built in, it is capable of handling virtual fonts information.
+
+In \LUATEX\ you can build your own virtual font and this will suit us well. It
+permits us for instance to complete fonts that lack certain characters (glyphs) and
+thereby let us get rid of ugly macro based fallback trickery. Although in \CONTEXT\
+we will provide a high level interface, we will give you a taste of \LUA\ here.

+\stoptyping
+
+Here we define a virtual font that uses three real fonts and
+which font is used depends on the kind of character we're
+dealing with (inreal world situations we can best use the \MKIV\ function
+that tells what class a character belongs to). The \type {commands}
+table determines what glyphs comes out in what way. We use a bit of
+literal pdf code to color the special characters but generally color is
+not handled at the font level.
+
+This example can be used like:

+\stoptyping
+
+During development of this mechanism, we decided to save some redundant
+loading by permitting id's in the fonts array:
+
+\starttyping
+callback.register("define_font", function(name,size)
+    if name == "demo" then
+        local f = font.read_tfm('texnansi-lmr10',size)
+        if f then
+            local id = font.define(f)
+            local capscale, digscale = 0.85, 0.75
+            f.name, f.type = name, 'virtual'
+            f.fonts = {
+                { id=id },

+            return f
+        end
+    end
+    return font.read_tfm(name,size)
+end)
+\stoptyping
+
+Hardwiring fontnames in callbacks this way does not deserve a price and
+when possible we will provide better extension interfaces. Anyhow,
+in the experimental \CONTEXT\ code we used calls like this, where
+\type {demo} is an installed feature.
+
+\startbuffer
+\font\myfont = special@demo-1 at 12pt \myfont

+\stopbuffer
+
+\typebuffer \start \getbuffer \par \stop
+
+Keep in mind that this is just an example. In practice we will not do such things
+at the font level but by manipulating \TEX's internals.
+
+While developing this functionality and especially when Taco was
+programming the backend functionality, we used more sane \MKIV\ code. Think
+of (still \LUA) definitions like:
+
+\startbuffer
+\ctxlua {
+    fonts.definers.methods.install("weird", {
+        { "copy-range",     "lmroman10-regular"                      } ,
+        { "copy-char",      "lmroman10-regular",          65,     66 } ,
+        { "copy-range",     "lmsans10-regular",       0x0100, 0x01FF } ,
+        { "copy-range",     "lmtypewriter10-regular", 0x0200, 0xFF00 } ,
+        { "fallback-range", "lmtypewriter10-regular", 0x0000, 0x0200 }
+    })
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Again, this is not the final user interface, but it shows the
+direction we're heading. The result looks like:
+
+\startbuffer
+\font\test={myfont@weird} at 12pt \test
+\eacute \rcaron \adoublegrave \char65
+\stopbuffer
+
+\typebuffer
+
+This shows up as:
+
+\start \getbuffer \stop
+
+Here the \type {@} tells the (new) \CONTEXT\ font handler what constructor
+should be used.
+
+Because some testers already have \XETEX\ font support files, we

+
+\startbuffer

+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\start \getbuffer \stop
+
+We are quite tolerant with regards to this specification and will provide less
+dense methods as well. Of course we need to implement a whole bunch of
+features but we will do this in such a way that we give users full control.
+
+\subject{encodings}
+
+By now we've reached a stage where we can get rid of font encodings. We now
+have the full unicode range available and no longer depend on the font
+encoding when we hyphenate. In a previous chapter we discussed the difference
+in size between formats.
+

+
+The size of the formats has grown a bit due to a few more
+patterns and a extra preloaded encoding. But the \LUATEX\
+format shrinks some 10\% now that we can get rid of encoding
+support. Some support for encodings is still present, so that
+one can keep using the metric files that are installed (for
+instance in project related trees that have special fonts)
+although \AFM/\TYPEONE\ files or \OPENTYPE\ fonts will be used when
+available.
+
+A couple of years from now, we may throw away some \LUA\ code
+related to encodings.
+
+\subject{files}
+
+\TEX\ distributions tend to be rather large, both in terms of
+files and bytes. Fonts take most of the space. The merged
+\TEX Live 2007 trees contain some 60.000 files that take
+1.123 MBytes. Of this, 25.000 files concern fonts totaling
+to 431 MBytes. A recent \CONTEXT\ distribution spans 1200 files and
+20 MBytes and a bit more when third party modules are taken into
+account. The fonts in \TEX Live are distributed as follows:

+We omitted the more obscure file types. The last two columns show the
+numbers for one of my local font trees.
+
+In due time we will see a shift from \TYPEONE\ to \OPENTYPE\ and \TRUETYPE\
+files and because these fonts are more
+complete, they may take some more space. More important is that the \TEX\ specific
+font metric files will phase out and the less \TYPEONE\ fonts we have, the less \AFM\
+companions we need (\AFM\ files are not compressed and therefore relatively
+large). Mapping and encoding files can also go away.
+
+In \LUATEX\ we can do with less files, but the number of bytes may grow a bit
+depending on how much is catched (especially fonts). Anyhow, we can safely
+assume that a \LUATEX\ based distributions will carry less files and less
+bytes around.
+
+\subject{fallbacks}
+
+Do we need virtual fonts? Currently in \CONTEXT, when a font encoding is chosen, a
+fallback mechanism steps in as soon as a character is not in the encoding. So far,
+so good. But occasionally we run into a font that does not (completely) fits an
+encoding and we end up with defining a non standard one. In traditional \TEX\
+a side effects of font encodings is that they relate to hyphenation. \CONTEXT\ can
+deal with that comfortably and multiple instances of the same set of hyphenation
+patterns can be loaded, but for custom encodings this is kind of cumbersome.
+
+In \LUATEX\ we have just one font encoding: \UNICODE. When \OPENTYPE\ fonts are used,
+we don't expect many problems related to missing glyphs, but you can bet on it that
+they will occur. This is where in \CONTEXT\ \MKIV\ fallbacks will be used and this
+will be implemented using vitual fonts. The advantage of using virtual fonts is that
+we still deal with proper characters and hyphenation will take place as expected. And
+since virtual fonts can be defined on the fly, we can be flexible in our implementation.
+We can think of generic fallbacks, not much different than macro based representations,
+or font specific ones, where we even may rely on \METAPOST\ for generating the glyph
+data.
+
+How do we define a fall back character. When building this mechanism I used the
+\quote {\textcent} as an example. A cent symbol is roughly defined as follows:
+
+\starttyping
+local t = table.fastcopy(g.characters[0x0063]) -- mkiv function
+local s = fonts.constructors.scaled(g.fonts[1].size)    -- mkiv function
+t.commands = {
+    {"push"},
+    {"slot", 1, c},
+    {"pop"},
+    {"right", .5*t.width},
+    {"down",  .2*t.height},
+    {"rule", 1.4*t.height, .02*s}
+}
+t.height = 1.2*t.height
+t.depth  = 0.2*t.height
+\stoptyping
+
+Here, \type {g} is a loaded font (table) which has type \type {virtual}. The
+first font in the \type {fonts} array is the main font. What happens here
+is the following: we assign the characteristics of \quote {c} to the cent
+symbol (this includes kerning and dimensions) and then define a command
+sequence that draws the \quote {c} and a vertical rule through it.
+
+The real code is slightly more complicated because we need to take care of
+italic properties when applicable and because we have added some tracing too.
+While playing with this kind of things, it becomes clear what features are
+handy, and the reason that we now have a virtual command \type {comment} is
+that it permits us to implement tracing (using for instance color specials).
+

+
+The previous lines are typeset using a similar specification as mentioned
+before:
+
+\starttyping
+\font\test=lmroman10-regular@demo-2
+\stoptyping
+
+Without the fallbacks we get:
+
+\TestLine {lmroman10-regular at 24pt}
+\TestLine {lmroman10-italic  at 24pt}
+
+And with normal (non forced fallbacks) it looks as follows. As it happens,
+this font has a cent symbol so no fallback is needed.
+
+\TestLine {lmroman10-regular@demo-3 at 24pt}
+\TestLine {lmroman10-italic@demo-3  at 24pt}
+
+The font definition callback intercepts the \type {demo-2} and a couple of
+chained lua functions make sure that characters missing in the font are
+replaced by fallbacks. In the case of missing composed characters, they are
+constructed from their components. In this particular example we have told
+the handler to assume that all composed characters are missing.
+
+\subject{memory}
+
+Traditional \TEX\ has been designed for speed and a small memory footprint. Todays
+implementations are considerably more generous with the amount of memory that
+you can use (hash, fonts, main memory, patterns, backend, etc). Depending
+on how complicated a document layout it, memory may run into tens of megabytes.
+
+Because \LUATEX\ is not only suitable for wide fonts, but also does away with some of
+the optimizations in the \TEX\ code that complicate extensions, it has a larger
+footprint that \PDFTEX. When implementing the \OPENTYPE\ font basics, we did quite
+some tests with respect to memory usage. Getting the numbers right is non trivial
+because the \LUA\ garbage collector is interfering. For instance, on my machine a
+test file with the regular \CONTEXT\ setup of of Latin Modern fonts made \LUA\
+allocate 130 MB, while the same run on Taco's machine took 100 MB.
+
+When a font data table is constructed, it is handled over to \TEX, and turned into
+the internal font data structures. During the construction of that \TABLE\ at the
+\LUA\ end, \CONTEXT\ \MKIV\ disables the garbage collector. By doing this, the time
+needed to construct and scale a font can be halved. Curious to the amount of memory
+involved in passing such a table, I added the following piece of code:
+
+\starttyping
+if type(fontdata) == "table" then
+    local s = statistics.luastate_bytes
+    local t = table.copy(fontdata)
+    local d = statistics.luastate_bytes-s
+    texio.write_nl(string.format("table memory footprint: %s",d))
+end
+\stoptyping
+
+It turned out that a Regular Latin Modern font (\OPENTYPE) takes around
+800 KB. However, more interesting was that by adding this snippet of testcode
+which duplicted the table in order to measure its size, the total memory footprint
+dropped to 100 MB (about the amount used on Taco's machine). This demonstrates
+that one should be very careful with drawing conclusions.
+
+Because fonts are rather important in \TEX\ and because there can be lots of
+them used, it makes sense to keep an eye on memory as well as performance.
+Because many manipulations now take place in \LUA, it no longer makes sense
+to let \TEX\ buffer fonts. In plain \TEX\ one finds these magic
+
+\starttyping
+\font\preloaded=cmr10
+\font\preloaded=cmr12
+\stoptyping
+
+lines. The second definitions obscures the first, but the \type {cmr10} stays
+loaded.
+
+\starttyping
+\font\one=cmr10 at 10pt
+\font\two=cmr10 at 10pt
+\stoptyping
+
+These two definitions make \TEX\ load the font only once. However, since
+we can now delegate loading to \LUA, \TEX\ no longer helps us there. For instance,
+\TEX\ has no knowledge to what extend this \type {cmr10} font has been manipulated
+and therefore both instances may actually differ.
+
+When you use a callback to define the font, \TEX\ passes a font id number. You can
+use this number as a reference to a loaded font (that is, passed to \TEX). If
+instead of a table, you return a number, \TEX\ will reuse the already loaded font.
+This feature can save you a lot of time, especially when a macro package (like
+\CONTEXT) defines  fonts dynamically which means that when grouping is used, fonts
+get (re)defined a lot. Of course additional caching can take place at the \LUA\ end,
+but there one needs to take into account more than just the scaled instance. Think of
+\OPENTYPE\ features or virtual font properties. The following are quite certainly
+different setups, in spite of the common size.
+
+\starttyping
+\font\one=lmr10@demo-1 at 10pt
+\font\two=lmr10@demo-2 at 10pt
+\stoptyping
+
+When scaling a font, one not only needs to handle the regular glyph dimensions, but also the
+kerning tables. We found out that dealing with such issues takes some 25\% of the time
+spent on loading Latin Modern fonts that have rather extensive kerning tables.
+When creating a virtual font, copying glyph tables may happen a lot. Deep copying
+tables takes a bit of time. This is one of the reasons why we discussed (and consider)
+some dedicated support functions so that copying and recalculating tables happens faster
+(less costly hash lookups and such).  On the other hand, the time wasted on calculations
+(including rounding to scaled points) can be neglected.
+
+The following table shows what happens when we enforce a different
+garbage collecting scheme. This test was triggered by another experiment
+where at regular time, for instance after a pag eis shipped out, say
+
+\starttyping
+collectgarbage("collect")
+\stoptyping
+
+However, such a complete sweep has drastic consequences for the runtime.
+But, since the memory footprint becomes 10--15\% less by doing so, we
+played a bit with
+
+\starttyping
+collectgarbage("setstepmul", somenumber)
+\stoptyping
+
+When processing a not so large file but one that loads a bunch of open type
+fonts, we get the following values. The left set is on linux (Taco's machine)
+and the right set in mine.

+
+\subject{introduction}
+
+We're closing in on the day that we will go beta with \LUATEX\ (end of July
+2007). By now we have a rather good picture of its potential and to what
+extend \LUATEX\ will solve some of our persistent problems. Let's first
+summarize our reasons for and objectives with \LUATEX.
+
+\startitemize
+
+\item The world has moved from 8~bits to 32~bits and more, and this is
+quite noticeable in the arena of fonts. Although \TYPEONE\ fonts could host
+more than 256 glyphs, the associated technology was limited to 256. The advent
+of \OPENTYPE\ fonts will make it easier to support multiple languages at the
+same time without the need to switch fonts at awkward times.
+
+\item At the same time \UNICODE\ is replacing 8~bit based encoding vectors and
+code pages (input regimes). The most popular and rather efficient \UTF8 encoding
+has become a de factor standard in document encoding and interchange.
+
+\item Although we can do real neat tricks with \TEX, given some nasty programming,
+we are touching the limits of its possibilities. In order for it to survive we
+need to extend the engine but not at the cost of base compatibility.
+
+\item Coding solutions in a macro language is fine, but sometimes you long to a more
+procedural approach. Manipulating text, handling \IO, interfacing \unknown\ the
+technology moves on and we need to move along too.
+
+\stopitemize
+
+Hence \LUATEX: a merge of the mainstream traditional \TEX\ engines, stripped from
+broken or incomplete features and opened up to an embedded \LUA\ scripting engine.
+
+We will describe the impact of this new engine by starting from its core components
+reflected in the specific \LUA\ interface libraries. Missing here is embedded support
+for \METAPOST, because it's not yet there (apart from the fact that we use \LUA\ to
+convert \METAPOST\ graphics into \TEX). Also missing is the interfacing to the \PDF\
+backend, which is also on the agenda for later. Special extensions, for instance those
+dealing with runtime statistics are also not discussed. Since we use \CONTEXT\ as
+testbed, we will refer to the \LUATEX\ aware version of this macro package, \MKIV, but
+most conclusions are rather generic.
+
+\subject{tex internals}
+
+In order to manipulate \TEX's data structures, we need access to all those registers.
+Already early in the development, dimension and counters were accessible and when
+token and node interfaces were implemented, those registers also were interfaced.
+
+Those who read the previous chapters will have noticed that we hardly discussed this
+option. The reason is that we didn't yet needed that access much in order to implement
+font support and list processing. After all, most of the data that we need to access and
+manipulate is not in the registers at all. Information meant for \LUA\ can be stored
+in \LUA\ data structures. In fact, the basic call
+
+\starttyping
+\directlua 0 {some lua code}
+\stoptyping
+
+has shown to be a pretty good starting point and the fact that one can print back to
+the \TEX\ engine overcomes the need to store results in shared variables.
+
+\starttyping
+\def\valueofpi{\directlua0{tex.sprint(math.pi()}}
+\stoptyping
+
+The number of such direct calls is not that large anyway. More often a call to \LUA\
+will be initiated by a callback, i.e.\ a hook into the \TEX\ machinery.
+
+What will be the impact of access on \CONTEXT\ \MKIV ? This is yet hard to tell. In a
+later stage of the development, when parts of the \TEX\ machinery will be rewritten in
+order to get rid of the current global nature of many variables, we will gain more
+control and access to \TEX's internals. Core functionality will be isolated, can be
+extended and|/|or overloaded and at that moment access to internals is much more
+needed. But certainly that will be beyond the current registers and variables.
+
+\subject{callbacks}
+
+These are the spine of \LUATEX: here both worlds communicate with each other. A callback
+is a place in the \TEX\ kernel where some information is passed to \LUA\ and some result
+is returned that is then used along the road. The reference manual mentions them all and
+we will not repeat them here. Interesting is that in \MKIV\ most of them are used and for
+tasks that are rather natural to their place and function.
+
+\starttyping
+callback.register("tex_wants_to_do_this",
+    function but_use_lua_to_do_it_instead(a,b,c)
+        -- do whatever you like with a, b and c
+        return a, b, c
+    end
+)
+\stoptyping
+
+The impact of callbacks on \MKIV\ is big. It provides us a way to solve persistent
+problems or reimplement existing solutions in more convenient ways. Because we tested
+realistic functionality on real (moderately complex) documents using a pretty large
+macro package, we can safely conclude that callbacks are quite efficient. Stepwise
+\LUA\ kicks in in order to:
+
+\startitemize[packed]
+\item influence the input medium so that it provides a sequence of \UTF\ characters
+\item manipulate the stream of characters that will be turned into a list of tokens
+\item convert the list of tokens into another list of tokens
+\item enhance the list of nodes that will be turned into a typeset paragraph
+\item tweak the mechanisms that come into play when lines are constructed
+\item finalize the result that will end up in the output medium
+\stopitemize
+
+Interesting is that manipulating tokens is less useful than it may look at first
+sight. This has to do with the fact that it's (mostly) an expanded stream and at that
+time we've lost some information or need to do quite some coding in order to analyze
+the information and act upon it.
+
+Will \CONTEXT\ users see any of this? Chances are small that they will, although we
+will provide hooks so that they can add special code themselves. Users activating
+a callback has some danger, since it may overload already existing functionality.
+Chaining functionality in a callback also has drawbacks, if only that one may be
+confronted with already processed results and|/|or may destroy this result in
+unpredictable ways. So, as with most low level \TEX\ features, \CONTEXT\ users will
+work with more abstract interfaces.
+
+\subject{in- and output}
+
+In \MKIV\ we will no longer use the \KPSE\ library directly. Instead we use a
+reimplementation in \LUA\ that not only is more efficient, but also more powerful:
+it can read from \ZIP\ files, use protocols, be more clever in searching, reencodes
+the input streams when needed, etc. The impact on \MKIV\ is large. Most \TEX\ code
+that deals with input reencoding has gone away and is replaced by \LUA\ code.
+
+Although it is not directly related with reading from the input medium, in that stage
+we also replaced verbatim handling code. Such (often messy) catcode related situations
+are now handled more flexible, thanks to fast catcode table switching (a new
+\LUATEX\ feature) and features like syntax highlighting can be made more neat.
+
+Buffers, a quite old but frequently used feature of \CONTEXT, are now kept in
+memory instead of files. This speeds up runs. Auxiliary data, aka multi||pass
+information, will no longer be stored in \TEX\ files but in \LUA\ files. In
+\CONTEXT\ we have one such auxiliary file and in \MKII\ this file is selectively
+filtered, but in \MKIV\ we will be less careful with memory and load all that
+data once. Such speed improvements compensate the fact that \LUATEX\ is somewhat
+slower than it's ancestor \PDFTEX. (Actually, the fact that \LUATEX\ is a bit
+slower that \PDFTEX\ is mostly due to the fact that it has \ALEPH\ code on
+board.)
+
+Users often wonder why there  are so many temporary files, but these mostly relate
+to \METAPOST\ support. These will go away once we have \METAPOST\ as a library.
+
+In a similar way support for \XML\ will be enriched. We already have experimental
+loaders, filters and other code, and integration is on the agenda. Since \CONTEXT\ uses
+\XML\ for some sub systems, this may have some impact.
+
+Other \IO\ related improvements involve debugging, error handling and logging. We can pop
+up helpers and debug screens (\MKIV\ can produce \XHTML\ output and then launch a
+browser). Users can choose more verbose logging of \IO\ and ask for log data to be
+formatted in \XML. These parts need some additional work, because in the end we will
+also reimplement and extend \TEX's error handling.
+
+Another consequence of this will be that we will be able to package \TEX\ more
+conveniently. We can put all the files that are needed into a \ZIP\ file so that we only
+need to ship that \ZIP\ file and a binary.
+
+
+\subject{font readers}
+
+Handling \OPENTYPE\ involves more that just loading yet another font format. Of course
+loading an \OPENTYPE\ file is a necessity but we need to do more. Such fonts come with
+features. Features can involve replacing one representation of a character by another
+one of combining sequences into other sequences and finaly resolving them to one or more
+glyphs.
+
+Given the numerous options we will have to spend quite some time on extending \CONTEXT\
+with new features. Instead of defining more and more font instances (the traditional \TEX\ way
+of doing things) we will will provides feature switching. In the end this will make
+the often confusing font mechanisms less complex for the user to understand. Instead of
+for instance loading an extra font (set) that provides old style numerals, we will
+decouple this completely from fonts and provide it as yet another property of a piece
+of text. The good news is that much of the most important machinery is alresady in
+place (ligature building and such). Here we also have to decide what we let \TEX\ do
+and what we do by processing node lists. For instance kerning and ligature building
+can either be done by \TEX\ or by \LUA. Given the fact that \TEX\ does some juggling
+with character kerning while determining hyphenation points, we can as well disable
+\TEX's kerning and let \LUA\ handle it. Thereby \TEX\ only has to deal with paragraph
+building. (After all, we need to leave \TEX\ some core functionality to deal with.)
+
+Another everlasting burden on macro writers and users is dealing with character
+representations missing from a font. Of course, since we use named glyphs in
+\CONTEXT\ \MKII\ already much of this can be hidden, but in \MKIV\ we can
+create virtual fonts on the fly and keep thinking in terms of characters and
+glyphs instead of dealing with boxes and other structures that don't go well with
+for instance hyphenating words.
+
+This brings us to hyphenation, historically bound to fonts in traditional \TEX. This
+dependency will go away. In \MKII\ we already ship \UTF8\ based patterns fore some time
+and these can be conveniently used in \MKIV\ too. We experimented with using hyphenated
+word lists and this looks promising. You may expect more advanced ways of dealing with
+words, hyphenation and paragraph building in the near future. When we presented the
+first version of \LUATEX\ a few years ago, we only had the basic \type {\directlua} call
+available and could do a bit of string manipulation on the input. A fancy demo was to
+color wrongly spelled words. Now we can do that more robustly on the node lists.
+
+Loading and preparing fonts for usage in \LUATEX\ or actually \MKIV\ because this depends
+on the macro package takes some runtime.  For this reason we introduces caching
+into \MKIV: data that is used frequently is written to a cache and converted to \LUA\
+bytecode. Loading the converted files is incredibly fast. Of course there is aprice to
+pay: disk space, but that comes cheap these days. Also, it may as well be compensated
+by the fact that we can kick out many redundant files from the core \TEX\ distributions
+(metric files for instance).
+
+\subject{tokens handlers}
+
+Do we need to handle tokens? So far in experimental \MKIV\ code we only used these hooks
+to demonstrate what \TEX\ does with your characters. For a while we also constructed
+token lists when we wanted to inject \type {\pdfliteral} code in node lists, but that
+became obsolete when automatic string to token conversion was introduced in the node
+conversion code. Now we inject literal whatsit nodes. It may be worth noticing that
+playing with token lists gave us some good insight in bottlenecks because quite some
+small table allocation and garbage collections goes on.
+
+\subject{nodes and attributes}
+
+These are the most promissing new features. In itself, nodes are not new, nor are
+attributes. In some sense when we use primitives like \type {\hbox}, \type {\vskip},
+\type {\lastpenalty} the result is a node, but we can only control and inspect their
+properties within hard coded bounds. We cannot really look into boxes, and the last
+penalty may be obscured by a whatsit (a mark, a special, a write, etc.). Attributes
+could be fakes with marks and macro bases stacks of states. Native attributes
+are more powerful and each node can cary a truckload of them.
+
+With \LUATEX, out of a sudden we can look into \TEX's internals and manipulate
+them. Although I don't claim to be a real expert on these internals, even after
+over a decade of \TEX\ programming, I'm sometimes surprised what I found there.
+When we are playing with these interfaces, we often run into situations
+where we need to add much print statements to the \LUA\ code in order to find
+out what \TEX\ is returning. It all has to do with the way \TEX\ collects
+information and when it decides to act. In regular \TEX\ much goes unnoticed, but
+when one has for instance a callback that deals with page building there are many
+places where this gets called and some of these places need special treatment.
+
+Undoubtely this will have a huge impact on \CONTEXT\ \MKIV. Instead of parsing
+an input stream, we can now manipulate node lists in order to achieve (slight)
+inter||character spacing which is often needed in sectioning titles. The nice
+thing about this new approach is that we no longer have interference from
+characters that need multiple tokens (input characters) in order to be
+constructed, which complicates parsing (needed to split glyphs in \MKII).
+
+Signaling where to letterspace is done with the mentioned attributes. There can be
+many of them and they behave like fonts: they obey grouping, travel with the nodes
+and are therefore insensitive for box and page splitting. They can be set at the
+\TEX\ end but needs to be handled at the \LUA\ side. One may wonder what kind
+of macro packages would be around when \TEX\ has attributes right from its start.
+
+In \MKII\ letterspacing is handled by parsing the input and injecting skips.
+Another approach would be to use a font where each character has more kerns or space
+around it (a virtual font can do that). But that would not only demand knowledge of
+what fonts need that that treatment, but also many more fonts and generating them is
+no fun for users. In \PDFTEX\ there is a letterspace feature, where virtual fonts
+are generated on the fly, and with such an approach one has to compensate for the
+first and last character in a line, in order to get rid of the left- and
+rightmost added space (being part of the glyph). The solution where nodes are
+manipulated does put that burden upon the user.
+
+Another example of node processing is adding specific kerns around some punctuation
+symbols, as is custom in French. You don't want to know what it takes to do that
+in traditional \TEX, but if I mention the fact that colons become active characters
+you can imagine the nightmare. Hours of hacking and maybe even days of dealing with
+mechanisms that make these active colons workable in places where colons are used
+for non text are now even more wasted time if you consider that it takes a few lines
+of code in \MKIV. Currently we let \CONTEXT\ support both good old \TEX\
+(represented by \PDFTEX), \XETEX\ (a \UNICODE\ and \OPENTYPE\ aware variant) and
+\LUATEX\ by shared and dedicated \MKII\ and \MKIV\ code.
+
+Vertical spacing can be a pain. Okay, currently \MKII\ has a rather sophisticated way to
+deal with vertical spacing in ways that give documents a consistent look and feel, but
+every now and then we run into border cases that cannot be dealt with simply because
+we cannot look back in time. This is needed because \TEX\ adds content to the main
+vertical list and then it's gone from our view. Take for instance section titles. We don't
+want them dangling at the bottom of a page. But at the same time we want itemized lists
+to look well, i.e.\ keep items together in some situations. Graphics that follow a section
+title pose similar problems. Adding penalties helps but these may come too late, or
+even worse, they may obscure previous skips which then cannot be dealt with by successive
+skips. To simplify the problem: take a skip of 12pt, followed by a penalty, followed by
+another skip of 24pt. In \CONTEXT\ this has to become a penalty followed by one skip
+of 24pt.
+
+Dealing with this in the page builder is rather easy. Ok, due to the way \TEX\ adds
+content to the page stream, we need to collect, treat and flush, but currently this
+works all right. In \CONTEXT\ \MKIV\ we will have skips with three additional properties:
+priority over other skips, penalties, and a category (think of: ignore, force,
+replace, add).
+
+When we experimented with this kind of things we quickly decided that additional
+experiments with grid snapping also made sense. These mechanisms are among the more
+complex ones on \CONTEXT. A simple snap feature took a few lines of \LUA\ code and
+hooking it into \MKIV\ was not that complex either. Eventually we will reimplement
+all vertical spacing and grid snapping code of \MKII\ in \LUA. Because one of
+\CONTEXT\ column mechanism is grid aware, we may as well adath that and|/|or implement
+an additional mechanism.
+
+A side effect of being able to do this in \LUATEX\ is that the code taken from \PDFTEX\
+is cleaned up: all (recently added) static kerning code is removed (inter||character
+spacing, pre- and post character kerning, experimental code that can fix the heights
+and depths of lines, etc.). The core engine will only deal with dynamic features,
+like \HZ\ and protruding.
+
+So, the impact on \MKIV\ of nodes and attributes is pretty big! Horizontal spacing isues,
+vertical spacing, grid snapping are just a few of the things we will reimplement. Other
+things are line numbering, multiple content streams with synchronization, both are
+already present in \MKII\ but we can do a better job in \MKIV.
+
+\subject{generic code}
+
+In the previous text \MKIV\ was mentioned often, but some of the features are rather
+generic in nature. So, how generic can interfaces be implemented? When the \MKIV\ code
+has matured, much of the \LUA\ and glue||to||\TEX\ code will be generic in nature.
+Eventually \CONTEXT\ will become a top layer on what we internally call \METATEX, a
+collection of kernel modules that one can use to build specialized macro packages.
+To some extent \METATEX\ can be for \LUATEX\ what plain is for \TEX. But if and how
+fast this will be reality depends on the amount of time that we (and other members of
+the \CONTEXT\ development team) can allocate to this.

+\chapter{Going \UTF}
+
+\LUATEX\ only understands input codes in the Universal Character
+Set Transformation Format, aka \UCS\ Transformation Format, better
+known as: \UTF. There is a good reason for this universal view
+on characters: whatever support gets hard coded into the programs,
+it's never enough, as 25 years of \TEX\ history have clearly
+demonstrated. Macro packages often support more or less standard
+input encodings, as well as local standards, user adapted ones,
+etc.
+
+There is enough information on the Internet and in books about what
+exactly is \UTF. If you don't know the details yet: \UTF\ is a
+multi||byte encoding. The characters with a bytecode up to 127 map
+onto their normal \ASCII\ representation. A larger number indicates
+that the following bytes are part of the character code. Up to 4~bytes
+make an \UTF-8 code, while \UTF-16 always uses two pairs of bytes.
+
+\starttabulate[|c|c|c|c|c|]
+\NC \bf byte 1 \NC \bf byte 2 \NC \bf byte 3 \NC \bf byte 4 \NC \bf unicode            \NC \NR
+\NC 192--223   \NC 128--191   \NC            \NC            \NC 0x80--0x7f{}f          \NC \NR
+\NC 224--239   \NC 128--191   \NC 128--191   \NC            \NC 0x800--0xf{}f{}f{}f    \NC \NR
+\NC 240--247   \NC 128--191   \NC 128--191   \NC 128--191   \NC 0x10000--0x1f{}f{}f{}f \NC \NR
+\stoptabulate
+
+In \UTF-8 the characters in the range $128$--$191$ are illegal
+as first characters. The characters 254 and 255 are
+completely illegal and should not appear at all since they are
+related to \UTF-16.
+
+Instead of providing a never|-|complete truckload of other input
+formats, \LUATEX\ sticks to one input encoding but at the same
+time provides hooks that permits users to write filters that
+preprocess their input into \UTF.
+
+While writing the \LUATEX\ code as well as the \CONTEXT\ input
+handling, we experimented a lot. Right from the beginning we had
+a pretty clear picture of what we wanted to achieve and how it
+could be done, but in the end arrived at solutions that permitted
+fast and efficient \LUA\ scripting as well as a simple interface.
+
+What is involved in handling any input encoding and especially
+\UTF?. First of all, we wanted to support \UTF-8 as well as
+\UTF-16. \LUATEX\ implements \UTF-8 rather straightforward: it
+just assumes that the input is usable \UTF. This means that
+it does not combine characters. There is a good reason for this:
+any automation needs to be configurable (on|/|off) and the more
+is done in the core, the slower it gets.
+
+In \UNICODE, when a character is followed by an \quote
+{accent}, the standard may prescribe that these two characters are
+replaced by one. Of course, when characters turn into glyphs, and
+when no matching glyph is present, we may need to decompose any
+character into components and paste them together from glyphs in
+fonts. Therefore, as a first step, a collapser was written. In the
+(pre|)|loaded \LUA\ tables we have stored information about
+what combination of characters need to be combined into another
+character.
+
+So, an \type {a} followed by an \type {`} becomes \type {à} and
+an \type {e} followed by \type {"} becomes \type {ë}. This
+process is repeated till no more sequences combine. After a few
+alternatives we arrived at a solution that is acceptably fast:
+mere milliseconds per average page. Experiments demonstrated that
+we can not gain much by implementing this in pure~C, but we did
+gain some speed by using a dedicated loop||over||utf||string
+function.
+
+A second \UTF\ related issue is \UTF-16. This coding scheme comes
+in two endian variants. We wanted to do the conversion in \LUA,
+but decided to play a bit with a multi||byte file read function.
+After some experiments we quickly learned that hard coding such
+methods in \TEX\ was doomed to be complex, and the whole idea
+behind \LUATEX\ is to make things less complex. The complexity has
+to do with the fact that we need some control over the different
+linebreak triggers, that is, (combinations of) character 10 and/or 13. In
+the end, the multi||byte readers were removed from the code and we
+ended up with a pure \LUA\ solution, which could be sped up by
+using a multi||byte loop||over||string function.
+
+Instead of hard coding solutions in \LUATEX\ a couple of fast
+loop||over||string functions were added to the \LUA\ string
+function repertoire and the solutions were coded in \LUA. We did
+extensive timing with huge \UTF-16 encoded files, and are
+confident that fast solutions can be found. Keep in mind that
+reading files is never the bottleneck anyway. The only drawback
+of an efficient \UTF-16 reader is that the file is loaded into
+memory, but this is hardly a problem.
+
+Concerning arbitrary input encodings, we can be brief. It's rather
+easy to loop over a string and replace characters in the $0$--$255$
+range by their \UTF\ counterparts. All one needs is to maintain
+conversion tables and \TEX\ macro packages have always done that.
+
+Yet another (more obscure) kind of remapping concerns those special
+\TEX\ characters. If we use a traditional \TEX\ auxiliary file, then
+we must make sure that for instance percent signs, hashes, dollars
+and other characters are handled right. If we set the catcode of
+the percent sign to \quote {letter}, then we get into trouble when
+such a percent sign ends up in the table of contents and is read in
+under a different catcode regime (and becomes for instance a comment
+symbol). One way to deal with such situations is to temporarily move
+the problematic characters into a private \UNICODE\ area and deal
+with them accordingly. In that case they no longer can interfere.
+
+Where do we handle such conversions? There are two places where
+we can hook converters into the input.
+
+\startitemize[n,packed]
+\item each time when we read a line from a file, i.e.\ we can hook
+      conversion code into the read callbacks
+\item using the special \type {process_input_buffer} callback which
+      is called whenever \TEX\ needs a new line of input
+\stopitemize
+
+Because we can overload the standard file open and read functions,
+we can easily hook the \UTF\ collapse function into the readers.
+The same is true for the \UTF-16\ handler. In \CONTEXT, for
+performance reasons we load such files into memory, which means
+that we also need to provide a special reader to \TEX. When
+handling \UTF-16, we don't need to combine characters so that stage
+is skipped then.
+
+So, to summarize this, here is what we do in \CONTEXT. Keep in
+mind that we overload the standard input methods and therefore
+have complete control over how \LUATEX\ locates and opens files.
+
+\startitemize[n]
+
+\item When we have a \UTF\ file, we will read from that file line
+      by line, and combine characters when collapsing is enabled.
+
+\item When \LUATEX\ wants to open a file, we look into the first
+      bytes to see if it is a \UTF-16\ file, in either big or
+      little endian format. When this is the case, we load the
+      file into memory, convert the data to \UTF-8, identify
+      lines, and provide a reader that will give back the file
+      linewise.
+
+\item When we have been told to recode the input (i.e.\ when we have
+      enabled an input regime) we use the normal line||by||line
+      reader and convert those lines on the fly into valid \UTF.
+      No collapsing is needed.
+
+\stopitemize
+
+Because we conduct our experiments in \CONTEXT\ \MKIV\ the code that
+we provide may look a bit messy and more complex than the previous
+description may suggest. But keep in mind that a mature macro
+package needs to adapt to what users are accustomed to. The fact
+that \LUATEX\ moved on to \UTF\ input does not mean that all the
+tools that users use and the files that they have produced over
+decades automagically convert as well.
+
+Because we are now living in a \UTF\ world, we need to keep that
+in mind when we do tricky things with sequences of characters, for
+instance in processing verbatim. When we implement verbatim in
+pure \TEX\ we can do as before, but when we let \LUA\ kick in, we
+need to use string methods that are \UTF-aware. In addition to
+the linked-in \UNICODE\ library, there are dedicated iterator
+functions added to the \type {string} namespace; think of:
+
+\starttyping
+for c in string.utfcharacters(str) do
+    something_with(c)
+end
+\stoptyping
+
+Occasionally we need to output raw 8-bit code, for instance
+to \DVI\ or \PDF\ backends (specials and literals). Of course
+we could have cooked up a truckload of conversion functions
+for this, but during one of our travels to a \TEX\ conference,
+we came up with the following trick.
+
+We reserve the top 256 values of the \UNICODE\ range, starting at
+hexadecimal value 0x110000, for byte output. When writing to an
+output stream, that offset will be subtracted. So, 0x1100A9 is written
+out as hexadecimal byte value A9, which is the decimal value 169, which
+in the Latin~1 encoding is the slot for the copyright sign.

+\chapter{Halfway}
+
+\subject{introduction}
+
+We are about halfway into the \LUATEX\ project now. At the time of
+writing this document we are only a few days away from version
+0.40 (the Bacho\TEX\ cq.\ \TEX Live version) and around euro\TEX\
+2009 we will release version 0.50. Starting with version 0.30
+(which we released around the conference of the Korean \TEX\ User
+group meeting) all one-decimal releases are supported and usable
+for (controlled) production work. We have always stated that all
+interfaces may change until they are documented to be stable, and
+we expect to document the first stable parts in version 0.50.
+Currently we plan to release version 1.00 sometime in 2012, 30
+years after \TEX82, with 0.60 and 0.70 in 2010, 0.80 and 0.90 in
+2011. But of course it might turn out different.
+
+In this update we assume that the reader knows what \LUATEX\ is and
+what it does.
+
+\subject{design principles}
+
+We started this project because we wanted an extensible engine.
+We chose \LUA\ as the glue language. We do not regret this choice as it
+permitted us to open up \TEX's internals reasonably well. There have been
+a few extensions to \TEX\ itself, and there will be a few more, but none
+of them are fundamental in the sense that they influence
+
+typesetting. Extending \TEX\ in that area is up to the macro package
+writer, who can use the \LUA\ language combined with \TEX\ macros. In a
+similar fashion we made some decisions about \LUA\ libraries that are
+included. What we have now is what you will get. Future versions of
+\LUATEX\ will have the ability to load additional libraries but these
+will not be part of the core distribution.  There is simply too much
+choice and we do not want to enter endless discussions about what is
+best. More flexibility would also add a burden on maintenance that we
+do not want. Portability has always been a virtue of \TEX\ and we want
+to keep it that way.
+
+\subject{lua scripting}
+
+Before 0.40 there could be multiple instances of the \LUA\ interpreter
+active at the same time, but we have now decided to limit the number of
+instances to just one. The reason is simple: sharing all functionality
+among multiple \LUA\ interpreter instances does more bad than good and
+\LUA\ has enough possibilities to create namespaces anyway. The new
+limit also simplifies the internal source code, which is a good
+thing. While the \type {\directlua} command is now sort of frozen, we
+might extend the functionality of \type {\latelua}, especially in
+relation to what is possible in the backend. Both commands still
+accept a number but this now refers to an index in a user||definable
+name table that will be shown when an error occurs.
+
+\subject {input and output}
+
+The current \LUATEX\ release permits multiple instances of \KPSE\
+which can be handy if you mix, for instance, a macro package and
+\MPLIB, as both have their own \quote{progname} (and engine) namespace.
+However, right from the start it has been possible to bring most input
+under \LUA\ control and one can overload the usual \KPSE\
+mechanisms. This is what we do in \CONTEXT\ (and probably only there).
+
+Logging, etc., is also under \LUA\ control. There is no support for
+writing to \TEX's opened output channels except for the log and the
+terminal. We are investigating limited write control to numbered
+channels but this has a very low priority.
+
+Reading from zip files and sockets has been available
+for a while now.
+
+Among the first things that have been implemented is a mechanism for
+managing category codes (\type{\catcode}) although this is not really
+needed for practical usage as we aim at full compatibility. It just
+makes printing back to \TEX\ from \LUA\ a bit more comfortable.
+
+\subject {interface to tex}
+
+Registers can always be accessed from \LUA\ by number and (when
+defined at the \TEX\ end) also by name. When writing to a register
+grouping is honored. Most internal registers can be accessed
+(mostly read-only). Box registers can be manipulated but users
+need to be aware of potential memory management issues.
+
+There will be provisions to use the primitives related to setting
+codes (lowercase codes and such). Some of this functionality will be
+available in version 0.50.
+
+\subject {fonts}
+
+The internal font model has been extended to the full \UNICODE\
+range. There are readers for \OPENTYPE, \TYPEONE, and traditional
+\TEX\ fonts. Users can create virtual fonts on the fly and have
+complete control over what goes into \TEX. Font specific features
+can either be mapped onto the traditional ligature and kerning
+mechanisms or be implemented in \LUA.
+
+We use code from \FONTFORGE\ that has been stripped to get a
+smaller code base. Using the \FONTFORGE\ code has the advantage
+that we get a similar view on the fonts in \LUATEX\ as in this
+editor which makes debugging easier and developing fonts more
+convenient.
+
+The interface is already rather stable but some of the keys in loaded
+tables might change. Almost all of the font interface will be stable
+in version 0.50.
+
+\subject {tokens}
+
+It is possible to intercept tokenization. Once intercepted, a token
+table can be manipulated before being piped back into \LUATEX.  We
+still support \OMEGA's translation processes but that might become
+obsolete at some point.
+
+Future versions of \LUATEX\ might use \LUA's so-called \quote {user data}
+concept but the interface will mostly be the same. Therefore this
+subsystem will not be frozen yet in version 0.50.
+
+\subject {nodes}
+
+Users have access to the node lists in various stages. This interface
+has already been quite stable for some time but some cleanup might
+still take place. Currently the node memory maintenance is still
+explicit, but eventually we will make releasing unused nodes automatic.
+
+We have plans for keeping more extensive information within
+a paragraph (initial whatsit) so that one can build alternative
+paragraph builders in \LUA. There will be a vertical packer (in
+addition to the horizontal packer) and we will open up the page
+builder (inserts etc.). The basic interface will be stable in version
+0.50.
+
+\subject {attributes}
+
+This new kid on the block is now available for most subsystems but
+we might change some of its default behaviour. As of 0.40 you can
+also use negative values for attributes. The original idea of
+using negative values for special purposes has been abandoned as
+we consider a secondary (faster and more efficient) limited
+variant. The basic principles will be stable around version 0.50,
+but we reserve the freedom to change some aspects of attributes
+until we reach version 1.00.
+
+\subject {hyphenation}
+
+In \LUATEX\ we have clearly separated hyphenation, ligature
+building and kerning. Managing patterns as well as hyphenation is
+reimplemented from scratch but uses the same principles as
+traditional \TEX. Patterns can be loaded at run time and exceptions
+are quite efficient now. There are a few extensions, like embedded
+discretionaries in exceptions and pre- as well as posthyphens.
+
+On the agenda is fixing some \quote{hyphenchar} related issues and future
+releases might deal with compound words as well. There are some
+known limitations that we hope to have solved in version 0.50.
+
+\subject {images}
+
+Image handling is part of the backend. This part of the \PDFTEX\
+code has been rewritten and can now be controlled from \LUA. There
+are already a few more options than in \PDFTEX\ (simple
+transformations). The image code will also be integrated in the
+virtual font handler.
+
+\subject {paragraph building}
+
+The paragraph builder has been rewritten in \CCODE\ (soon to be
+converted back to \CWEB). There is a callback related to the builder
+so it is possible to overload the default line breaker by one written
+in \LUA.
+
+There are no further short|-|term revisions on the agenda, apart from
+writing an advanced (third order) Arabic routine for the Oriental
+\TEX\ project.
+
+Future releases may provide a bit more control over \type{\parshape}s
+and multiple paragraph shapes.
+
+\subject {metapost}
+
+The closely related \MPLIB\ project has resulted in a \METAPOST\
+library that is included in \LUATEX. There can be multiple
+instances active at the same time and \METAPOST\ processing is
+very fast. Conversion to \PDF\ is to be done with \LUA.
+
+On the to-do list is a bit more interoperability (pre- and
+postscript tables) and this will make it into release 0.50
+(maybe even in version 0.40 already).
+
+\subject {mathematics}
+
+Version 0.50 will have a stable version of \UNICODE\
+math support. Math is backward compatible but provides solutions
+for dealing with \OPENTYPE\ math fonts. We provide math lists in
+their intermediate form (noads) so that it is possible to
+manipulate math in great detail.
+
+The relevant math parameters are reorganized according to what
+\OPENTYPE\ math provides (we use the Cambria font as our reference). Parameters
+are grouped by style. Future versions of \LUATEX\ will build upon
+this base to provide a simple mechanism for switching style sets
+and font families in-formula.
+
+There are new primitives for placing accents (top and bottom
+variants and extensible characters), creating radicals, and making
+delimiters. Math characters are permitted in text mode.
+
+There will be an additional alignment mechanism analogous to
+what \MATHML\ provides. Expect more.
+
+\subject {page building}
+
+Not much work has been done on opening up the page builder
+although we do have access to the intermediate lists. This
+is unlikely to happen before 0.50.
+
+\subject {going cweb}
+
+After releasing version 0.50 around Euro\TEX\ 2009 there will be a
+period of relative silence. Apart from bug fixes and (private)
+experiments there will be no release for a while. At the time of the
+0.50 release the \LUATEX\ source code will probably be in plain C
+completely. After that is done, we will concentrate hard on
+consolidating and upgrading the code base back into \CWEB.
+
+\subject {cleanup}
+
+Cleanup of code is a continuous process. Cleanup is needed because
+we deal with a merge of traditional \TEX, \ETEX\ extensions,
+\PDFTEX\ functionality and some \OMEGA\ (\ALEPH) code.
+
+Compatibility is a prerequisite, with the exception of logging and
+rather special ligature reconstruction code.
+
+We also use the opportunity to slowly move away from all the global
+variables that are used in the \PASCAL\ version.
+
+\subject {alignments}
+
+We do have some ideas about opening up alignments, but it has a
+low priority and it will not happen before the 0.50 release.
+
+\subject {error handling}
+
+Once all code is converted to \CWEB, we will look into error
+handling and recovery. It has no high priority as it is easier to
+deal with after the conversion to \CWEB.
+
+\subject {backend}
+
+The backend code will be rewritten stepwise. The image related
+code has already been redone, and currently everything related to
+positioning and directions is redesigned and made more consistent.
+Some bugs in the \ALEPH\ code (inherited from \OMEGA) have been
+removed and we are trying to come up with a consistent way of dealing
+with directions. Conceptually this is somewhat messy because much
+directionality is delegated to the backend.
+
+We are experimenting with positioning (preroll) and better literal
+injection. Currently we still use the somewhat fuzzy \PDFTEX\ methods
+that evolved over time (direct, page and normal injection) but we
+will come up with a clearer model.
+
+Accuracy of the output (\PDF) will be improved and character
+extension (hz) will be done more efficiently. Experimental code
+seems to work okay. This will become available from release 0.40
+and onwards and further cleanup will take place when the \CWEB\
+code is there, as much of the \PDF\ backend code is already \CCODE.
+
+\subject{context mkiv}
+
+When we started with \LUATEX\ we decided to use a branch of
+\CONTEXT\ for testing as it involves quite drastic changes, many
+rewrites, a tight connection with binary versions, etc.
+
+As a result for some time we now have two versions of \CONTEXT: \MKII\
+and \MKIV, where the former targets \PDFTEX\ and \XETEX, and
+the latter exclusively uses \LUATEX. Although the user interface
+is downward compatible the code base starts to diverge more and
+more. Therefore at the last \CONTEXT\ meeting it was decided to
+freeze the current version of \MKII\ and only apply bug fixes
+and an occasional simple extension.
+
+This policy change opened the road to rather drastic splitting of the
+code, also because full compatibility between \MKII\ and \MKIV\ is not
+required. Around \LUATEX\ version 0.40 the new, currently still
+experimental, document structure related code will be merged into the
+regular \MKIV\ version. This might have some impact as it opens up new
+possibilities.
+
+\subject {the future}
+
+In the future, \MKIV\ will try to create (more) clearly separated
+layers of functionality so that it will become possible to make
+subsets of \CONTEXT\ for special purposes. This is done under the name
+\METATEX. Think of layering like:
+
+\startitemize[packed]
+\item \IO, catcodes, callback management, helpers
+\item input regimes, characters, filtering
+\item nodes, attributes and noads
+\item user interface
+\item languages, scripts, fonts and math
+\item spacing, par building and page construction
+\item \XML, graphics, \METAPOST, job management, and structure (huge impact)
+\item modules, styles, specific features
+\item tools

+\subject{fonts}
+
+At this moment \MKIV\ is already quite capable of dealing with
+\OPENTYPE\ fonts. The driving force behind this is the Oriental
+\TEX\ project which brings along some very complex and feature
+rich Arabic font technology. Much time has gone into reverse
+engineering the specification and behaviour of how these fonts
+behave in Uniscribe (which we use as our reference for Arabic).
+
+Dealing with the huge \CJK\ fonts is less a font issue and more
+a matter of node list processing. Around the annual meeting of
+the Korean User Group we got much of the machinery working, thanks
+to discussions on the spot and on the mailing list.
+
+\subject {math}
+
+Between \LUATEX\ versions 0.30 and 0.40 the math machinery was opened
+up (stage one). In order to test this new functionality, \MKIV's math
+subsystem (that was then already partially \UNICODE\ aware) had to be
+adapted.
+
+First of all \UNICODE\ permits us to use only one math family and so
+\MKIV\ now does that.  The implementation uses Microsoft's Cambria
+Math font as a benchmark. It creates virtual fonts from the other (old
+and new) math fonts so they appear to match up to Cambria
+Math. Because the \TEX\ Gyre math project is not yet up to speed \MKIV\
+currently uses virtual variants of these fonts that are created at
+run time. The missing pieces in for instance Latin Modern and friends
+are compensated for by means of virtual characters.
+
+Because it is now possible to parse the intermediate noad lists \MKIV\ can
+do some manipulations before the formula is typeset. This is for
+instance used for alphabet remapping, forcing sizes, and spacing
+around punctuation.
+
+Although \MKIV\ already supports most of the math that users expect
+there is still room for improvement once there is even more control
+over the machinery. This is possible because \MKIV\ is not bound to
+downward compatibility.
+
+As with all other \LUATEX\ related \MKIV\ code, it is expected that we
+will have to rewrite most of the current code a few times as we
+proceed, so \MKIV\ math support is not yet stable either. We can take
+such drastic measures because \MKIV\ is still experimental and because
+users are willing to do frequent synchronous updating of macros and
+engine. In the process we hope to get away from all ad||hoc boxing and
+kerning and whatever solutions for creating constructs, by using
+the new accent, delimiter, and radical primitives.
+
+\subject {tracing and testing}
+
+Whenever possible we add tracing and visualization features to
+\CONTEXT\ because the progress reports and articles need them. Recent
+extensions concerned tracing math and tracing \OPENTYPE\ processing.
+
+The \OPENTYPE\ tracing options are a great help in stepwise
+reaching the goals of the Oriental \TEX\ project. This project
+gave the \LUATEX\ project its initial boost and aims at high
+quality right|-|to|-|left typesetting. In the process complex (test)
+fonts are made which, combined with the tracing mentioned, help us
+to reveal the secrets of \OPENTYPE.

+\chapter{From \MKII\ to \MKIV}
+
+Sometime in 2005 the development of \LUATEX\ started, a further
+development of \PDFTEX\ and a precursor to \PDFTEX\ version~2. This
+\TEX\ variant will provide:
+
+\startitemize[packed]
+\item 21--32 bit internals plus a code cleanup
+\item flexible support for \OPENTYPE\ fonts
+\item an internal \UTF\ data flow
+\item the bidirectional typesetting of \ALEPH
+\item \LUA\ callbacks to the most relevant \TEX\ internals
+\item some extensions to \TEX\ (for instance math)
+\item an efficient way to communicate with \METAPOST
+\stopitemize
+
+In the tradition of \TEX\ this successor will be downward
+compatible in most essential parts and in the end, there is
+still \PDFTEX\ version~1 as fall back.
+
+In the mean time we have seen another unicode variant show up,
+\XETEX\ which is under active development, uses external
+libraries, provides access to the fonts on the operating system,
+etc.
+
+From the beginning, \CONTEXT\ always worked with all engines. This
+was achieved by conditional code blocks: depending on what engine
+was used, different code was put in the format and|/|or used at
+runtime. Users normally were unaware of this. Examples of engines
+are \ETEX, \ALEPH, and \XETEX. Because nowadays all engines
+provide the \ETEX\ features, in August 2006 we decided to consider
+those features to be present and drop providing the standard \TEX\
+compatible variants. This is a small effort because all code that
+is sensitive for optimization already has \ETEX\ code branches for
+many years.
+
+However, with the arrival of \LUATEX, we need a more drastic approach.
+Quite some existing code can go away and will be replaced by different
+solutions. Where \TEX\ code ends up in the format file, along with
+its state, \LUA\ code will be initiated at run time, after a \LUA\
+instance is started. \CONTEXT\ reserves its own instance of \LUA.
+
+Most of this will go unnoticed for the users because the user
+interface will not change. For developers however, we need to
+provide a mechanism to deal with these issues. This is why, for the
+first time in \CONTEXT's history we will officially use a kind of
+version tag. When we changed the low level interface from Dutch to
+English we jokingly talked of version~2. So, it makes sense to
+follow this lead.
+
+\startitemize[packed]
+
+\item \notabene {\CONTEXT\ \MKI}\quad At that moment we still had a
+low level Dutch interface, invisible for users but not for developers.
+
+\item \notabene {\CONTEXT\ \MKII}\quad We now have a low level English
+interface, which (as we indeed saw happen) triggers more development by
+users.
+
+\item \notabene {\CONTEXT\ \MKIV}\quad This is the next generation of
+\CONTEXT, with parts re||implemented. It's an at some points drastic
+system overhaul.
+
+\stopitemize
+
+Keep in mind that the functionality does not change, although in
+some places, for instance fonts, \MKIV\ may provide additional
+functionality. The reason why most users will not notice the
+difference (maybe apart from performance and convenience) is that at
+the user interface level nothing changes (most of it deals with
+typesetting, not with low level details).
+
+The hole in the numbering permits us to provide a \MKIII\ version
+as well. Once \XETEX\ is stable, we may use that slot for \XETEX\
+specific implementations.
+
+As per August 2006 the banner is adapted to this distinction:
+
+\starttyping
+...  ver: 2006.09.06 22:46 MK II  fmt: 2006.9.6  ...
+...  ver: 2006.09.06 22:47 MK IV  fmt: 2006.9.6  ...
+\stoptyping
+
+This numbering system is reflected at the file level in such a way
+that we can keep developing the way we do, i.e.\ no files all over
+the place, in subdirectories, etc.
+
+Most of the system's core files are not affected, but some may be, like
+those dealing with fonts, input- and output encodings, file handling,
+etc. Those files may come with different suffixes:
+
+\startitemize
+
+\item \type {somefile.tex}: the main file, implementing the interface
+and common code
+
+\item \type {somefile.mkii}: mostly existing code, suitable for good
+old \TEX\ (\ETEX, \PDFTEX, \ALEPH).
+
+\item \type {somefile.mkiv}: code optimized for use with \LUATEX, which
+could follow completely different approaches
+
+\item \type {somefile.lua}: \LUA\ code, loaded at format generation time
+and|/|or runtime
+
+\stopitemize
+
+As said, some day \type {somefile.mkiii} code may show up. Which
+variant is loaded is determined automatically at format generation
+time as well as at run time.

+\chapter{Initialization revised}
+
+Initializing \LUATEX\ in such a way that it does what you want it
+to do your way can be tricky. This has to do with the fact that
+if we want to overload certain features (using callbacks) we need
+to do that before the orginals start doing their work. For
+instance, if we want to install our own file handling, we must
+make sure that the built||in file searching does not get
+initialized. This is particularly important when the built in
+search engine is based on the \KPSE\ library. In that case the
+first serious file access will result in loading the \type {ls-R}
+filename databases, which will take an amount of time more or less
+linear with the size of the \TEX\ trees. Among the reasons why we
+want to replace \KPSE\ are the facts that we want to access \ZIP\
+files, do more specific file searches, use \HTTP, \FTP\ and whatever
+comes around, integrate \CONTEXT\ specific methods, etc.
+
+Although modern operating systems will cache files in memory,
+creating the internal data structures (hashes) from the rather
+dumb files take some time. On the machine where I was developing
+the first experimental \LUATEX\ code, we're talking about 0.3
+seconds for \PDFTEX. One would expect a \LUA\ based alternative to
+be slower, but it is not. This may be due to the different
+implementation, but for sure the more efficient file cache plays a
+role as well. So, by completely disabling \KPSE, we can have more
+advanced \IO\ related features (like reading from \ZIP\ files) at
+about the same speed (or even faster). In due time we will also
+support progname (and format) specific caches, which speeds up
+loading. In case one wonders why we bother about a mere few
+hundreds of milliseconds: imagine frequent runs from an editor or
+sub||runs during a job. In such situation every speed up matters.
+
+So, back to initialization: how do we initialize \LUATEX. The
+method described here is developed for \CONTEXT\ but is not
+limited to this macro package; when one tells \TEXEXEC\ to
+generate formats using the \type {--luatex} directive, it will
+generate the \CONTEXT\ formats as well as \MPTOPDF\ using this
+engine.
+
+For practical reasons, the Lua based \IO\ handler is \KPSE\
+compliant. This means that the normal \type {texmf.cnf} and \type
+{ls-R} files can be used. However, their content is converted in a
+more \LUA\ friendly way. Although this can be done at runtime, it
+makes more sense to to this in advance using \LUATOOLS.  The files
+involved are:
+
+\starttabulate[|l|l|l|l|]
+\NC \bold{input}     \NC \bold{raw input} \NC \bold{runtime input}     \NC \bold{runtime fallback}  \NC \NR
+\NC                  \NC \type{ls-R}      \NC \type{files.luc}         \NC \type{files.lua}         \NC \NR
+\NC \type{texmf.lua} \NC \type{temxf.cnf} \NC \type{configuration.luc} \NC \type{configuration.lua} \NC \NR
+\stoptabulate
+
+In due time \LUATOOLS\ will generate the directory listing itself
+(for this some extra libraries need to be linked in). The
+configuration file(s) eventually will move to a \LUA\ table
+format, and when a \type {texmf.lua} file is present, that one
+will be used.
+
+\starttyping
+luatools --generate
+\stoptyping
+
+This command will generate the relevant databases. Optionally you can
+provide \type {--minimize} which will generate a leaner database, which
+in turn will bring down loading time to (on my machine) about 0.1 sec
+instead of 0.2 seconds. The \type {--sort} option will give nicer
+intermediate (\type {.lua}) files that are more handy for debugging.
+
+When done, you can use \LUATOOLS\ roughly in the same manner as
+\KPSEWHICH, for instance to locate files:
+
+\starttyping
+luatools texnansi-lmr10.tfm
+luatools --all tufte.tex
+\stoptyping
+
+You can also inspect its internal state, for instance with:
+
+\starttyping
+luatools --variables  --pattern=TEXMF
+luatools --expansions --pattern=context
+\stoptyping
+
+This will show you the (expanded) variables from the configuration
+files. Normally you don't need to go that deep into the belly.
+
+The \LUATOOLS\ script can also generate a format and run \LUATEX.
+For \CONTEXT\ this is normally done with the \TEXEXEC\ wrapper,
+for instance:
+
+\starttyping
+texexec --make --all --luatex
+\stoptyping
+
+When dealing with this process we need to keep several things in
+mind:
+
+\startitemize[packed]
+\item \LUATEX\ needs a \LUA\ startup file in both ini and runtime mode
+\item these files may be the same but may also be different
+\item here we use the same files but a compiled one in runtime mode
+\item we cannot yet use a file location mechanism
+\stopitemize
+
+A \type {.luc} file is a precompiled \LUA\ chunk. In order to
+guard consistency between \LUA\ code and tex code, \CONTEXT\ will
+preload all \LUA\ code and store them in the bytecode table
+provided by \LUATEX. How this is done, is another story. Contrary
+to these tables, the initialization code can not be put into the
+format, if only because at that stage we still need to set up
+memory and other parameters.
+
+In our case, especially because we want to overload the \IO\
+handler, we want to store the startup file in the same path as the
+format file. This means that scripts that deal with format
+generation also need to take care of (relocating) the startup
+file. Normally we will use \TEXEXEC\ but we can also use \LUATOOLS.
+
+Say that we want to make a plain format. We can call \LUATOOLS\
+as follows:
+
+\starttyping
+luatools --ini plain
+\stoptyping
+
+This will give us (in the current path):
+
+\starttyping
+120,808 plain.fmt
+  2,650 plain.log
+ 80,767 plain.lua
+ 64,807 plain.luc
+\stoptyping
+
+From now on, only the \type {plain.fmt} and \type {plain.luc} file
+are important. Processing a file
+
+\starttyping
+test \end
+\stoptyping
+
+can be done with:
+
+\starttyping
+luatools --fmt=./plain.fmt test
+\stoptyping
+
+This returns:
+
+\starttyping
+This is luaTeX, Version 3.141592-0.1-alpha-20061018 (Web2C 7.5.5)
+(./test.tex [1] )
+Output written on test.dvi (1 page, 260 bytes).
+Transcript written on test.log.
+\stoptyping
+
+which looks rather familiar. Keep in mind that at this stage we
+still run good old Plain \TEX. In due time we will provide a few
+files that will making work with \LUA\ more convenient in Plain
+\TEX, but at this moment you can already use for instance \type
+{\directlua}.
+
+In case you wonder how this is related to \CONTEXT, well only to
+the extend that it uses a couple of rather generic \CONTEXT\
+related \LUA\ files.
+
+\CONTEXT\ users can best use \TEXEXEC\ which will relocate the
+format related files to the regular engine path. In \LUATOOLS\
+terms we have two choices:
+
+\starttyping
+luatools --ini cont-en
+luatools --ini --compile cont-en
+\stoptyping
+
+The difference is that in the first case \type {context.lua} is
+used as startup file. This \LUA\ file creates the \type
+{cont-en.luc} runtime file. In the second call \LUATOOLS\ will
+create a \type {cont-en.lua} file and compile that one. An even
+more specific call would be:
+
+\starttyping
+luatools --ini --compile --luafile=blabla.lua          cont-en
+luatools --ini --compile --lualibs=bla-1.lua,bla-2.lua cont-en
+\stoptyping
+
+This call does not make much sense for \CONTEXT. Keep in mind
+that \LUATOOLS\ does not set up user specific configurations, for
+instance the \type {--all} switch in \TEXEXEC\ will set up all
+patterns.
+
+I know that it sounds a bit messy, but till we have a more clear
+picture of where \LUATEX\ is heading this is the way to proceed.
+The average \CONTEXT\ user won't notice those details, because
+\TEXEXEC\ will take care of things.
+
+Currently we follow the \TDS\ and \WEBC\ conventions, but in the
+future we may follow different or additional approaches. This may
+as well be driven by more complex \IO\ models. For the moment
+extensions still fit in. For instance, in order to support access
+to remote resources and related caching, we have added to the
+configuration file the variable:
+
+\starttyping
+TEXMFCACHE = $TMP;$TEMP;$TMPDIR;$HOME;$TEXMFVAR;$VARTEXMF;.

+\chapter{Introduction}
+
+In this document I will keep track of the transition of \CONTEXT\
+from \MKII\ to \MKIV, the latter being the \LUA\ aware version.
+
+The development of \LUATEX\ started with a few email exchanges
+between me and Hartmut Henkel. I had played a bit with \LUA\ in
+\SCITE\ and somehow felt that it would fit into \TEX\ quite well.
+Hartmut made me a version of \PDFTEX\ which provided a \type
+{\lua} command. After exploring this road a bit Taco Hoek\-water
+took over and we quickly reached a point where the \PDFTEX\
+development team could agree on following this road to the future.
+
+The development was boosted by a substantial grant from Colorado
+State University in the context of the Oriental \TEX\ Project of
+Idris Samawi Hamid. This project aims at bringing features into
+\TEX\ that will permit \CONTEXT\ to do high quality Arabic
+typesetting. Due to this grant Taco could spent substantial time
+on development, which in turn meant that I could start playing
+with more advanced features.
+
+This document is not so much a users manual as a history
+of the development. Consider it a collection of articles, and some
+chapters indeed have ended up in the journals of user groups. Things
+may evolve and the way things are done may change, but it felt right
+to keep track of the process this way. Keep in mind that some features
+may have changed while \LUATEX\ matured.
+
+Just for the record: development in the \LUATEX\ project is done
+by Taco Hoekwater, Hartmut Henkel and Hans Hagen. Eventually, the
+stable versions will become \PDFTEX\ version~2 and other members
+of the \PDFTEX\ team will be involved in development and
+maintenance. In order to prevent problems due to new and maybe
+even slightly incompatible features, \PDFTEX\ version~1 will be kept
+around as well, but no fundamentally new features will be added to
+it. For practical reasons we use \LUATEX\ as the name of the
+development version but also for \PDFTEX~2. That way we can use
+both engines side by side.
+
+This document is also one of our test cases. Here we use traditional
+\TEX\ fonts (for math), \TYPEONE\ and \OPENTYPE\ fonts. We use color
+and include test code. Taco and I always test new versions of
+\LUATEX\ (the program) and \MKIV\ (the macros and \LUA\ code) with
+this document before a new version is released. It also means that
+there can be temporary flaws in the rendering. Keep tuned,

+\chapter{It works!}
+
+One of the more powerful commands in \CONTEXT\ is \type {\framed}.
+You can pass quite some parameters that control the spacing,
+alignment, backgrounds and more. This command is used all over the
+place (although often hidden for the user) which means that it also has
+to be quite stable. However, there is one nasty bit of code that
+is hard to get right. Calculating the height of a box is not that
+complex: the height that \TEX\ reports is indeed the height.
+However, the width of box is determined by the value of \type
+{\hsize} at the time of typesetting. The actual content can be
+smaller. In the \type {\framed} macro by default the width is
+calculated automatically.
+
+\startbuffer
+\framed
+  [align=middle,width=fit]
+  {Out beyond the ethernet the spectrum spreads \unknown}

+this shows up as:\footnote{Taken from \quote {Casino Nation} by Jackson Browne.}

+
+\startbuffer
+\hsize=.6\hsize \framed [align=middle,width=fit] {\input weisman }
+\stopbuffer
+
+\typebuffer
+
+This gives a multi|-|line paragraph:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+Here the outer \type {\hsize} was made a bit smaller. As you can
+see the frame is determined by the widest line. Because it was one
+of the first features we needed, the code in \CONTEXT\ that is
+involved in determining the maximum natural width is pretty old.
+It boils down to unboxing a \type {\vbox} and stepwise grabbing
+the last box, penalty, kern and skip. You unwind the box
+backwards. However, you cannot grab everything or in \TEX\ speak:
+there is only a limited number of \type {\lastsomething} commands.
+Special nodes, like whatsits cannot be grabbed and they make the
+analyzer abort its analysis. There is no way that we can solve
+this in traditional \TEX\ and in \CONTEXT\ \MKII.
+
+So how about \LUATEX\ and \CONTEXT\ \MKIV ? The macro used in the
+\type {\framed} commands is:
+
+\starttyping
+\doreshapeframedbox{do something with \box\framebox}
+\stoptyping
+
+In \LUATEX\ we can manipulate box content at the \LUA\ level. Instead
+of providing a truckload of extra primitives (which would also introduce
+new data types at the \TEX\ end) we just delegate the job to \LUA.
+
+\starttyping
+\def\doreshapeframedbox
+  {\ctxlua{commands.doreshapeframedbox(\number\framebox)}}
+\stoptyping
+
+Here \type {\ctxlua} is our reserved instance and \type {commands}
+provides the namespace for commands that we delegate to \LUA\ (so,
+there are more of them). The amount of \LUA\ code is way less than
+the \TEX\ code which we will not show here; it's in \type
+{supp-box.tex} if you really want to see it.
+
+\starttyping
+function commands.doreshapeframedbox(n)
+    local box_n = tex.box[n]
+    if box_n.width ~= 0 then
+        local hpack = node.hpack
+        local free = node.free
+        local copy = node.copy_list
+        local noflines, lastlinelength, width = 0, 0, 0
+        local list = box_n.list
+        local done = false
+        for h in node.traverse_id('hlist',list) do
+            done = true
+            local p = hpack(copy(h.list))
+            lastlinelength = p.width
+            if lastlinelength > width then
+                width = lastlinelength
+            end
+            free(p)
+        end
+        if done then
+            if width ~= 0 then
+                for h in node.traverse_id('hlist',list) do
+                    if h.width ~= width then
+                        h.list = hpack(h.list,width,'exactly')
+                        h.width = width
+                    end
+                end
+            end
+            box_n.width = width
+        end
+        -- we can also do something with lastlinelength
+    end
+end
+\stoptyping
+
+In the first loop we inspect all lines (nodes with type \type
+{hlist}) and repack them to their natural width with \type
+{node.hpack}. In the process we keep track of the maximum natural
+width. In the second loop we repack the content again, but this
+time permanently. Now we use the maximum encountered width which
+is forced by the keyword \type {exactly}. Because all glue is
+still present we automatically get the desired alignment. We
+create local shortcuts to some node functions which makes it run
+faster; keep in mind that this is a core function called many
+times in a regular \CONTEXT\ job.
+
+In \CONTEXT\ \MKIV\ you will find quite some \LUA\ code and often
+it looks rather complex, especially if you have no clue why it's
+needed. Think of \OPENTYPE\ font handling which involves locating
+fonts, loading and caching them, storing features and later on
+applying them to node lists, etc. However, once we are beyond the
+stage of developing all the code that is needed to support the
+basics, we will start doing the things that more relate to the
+typesetting process itself, like the previous code. One of the
+candidates for a similar \LUA\ based solution is for instance
+column balancing. From the previous example code you can deduce
+that manipulating the node lists from \LUA\ can make that easier.
+Of course we're a few more years down the road then.

+\chapter{Where do we stand}
+
+In the previous chapter we discussed the state of \LUATEX\ in the
+beginning of 2009, the prelude to version 0.50. We consider the
+release of the 0.50 version to be a really important, both for
+\LUATEX\ and for \MKIV\ so here I will reflect on the state
+around this release. I will do this from the perspective of
+processing documents because useability is an important measure.
+
+There are several reasons why \LUATEX\ 0.50 is an important release,
+both for \LUATEX\ and for \MKIV. Let's start with \LUATEX.
+
+\startitemize
+
+\startitem Apart from a couple of bug fixes, the current version
+is pretty usable and stable. Details of what we've reached so far
+have been presented previously. \stopitem
+
+\startitem The code base has been converted from \PASCAL\ to
+\CCODE, and as a result the source tree has become simpler (being
+\CWEB\ compliant happens around 0.60). This transition also opens
+up the possibility to start looking into some of the more tricky
+internals, like page building. \stopitem
+
+\startitem Most of the front end has been opened up and the new
+backend code is getting into shape. As the backend was partly already done in
+\CCODE\ the moment has come to do a real cleanup. Keep in mind that
+we started with \PDFTEX\ and that much of its extra functionality is
+rather interwoven with traditional \TEX\ code. \stopitem
+
+\stopitemize
+
+If we look at \CONTEXT, we've also reached a crucial point in the
+upgrade.
+
+\startitemize
+
+\startitem The code base is now divided into \MKII\ and \MKIV. This
+permits us not only to reimplement bits and pieces (something that
+was already in progress) but also to clean up the code (only
+\MKIV). \stopitem
+
+\startitem If you kept up with the development you already know
+the kind of tasks we can (and do) delegate to \LUA. Just to
+mention a few: file handling, font loading and \OPENTYPE\
+processing, casing and some spacing issues, everything related to
+graphics and \METAPOST, language support, color and other
+attributes, input regimes, \XML, multi|-|pass data, etc. \stopitem
+
+\startitem Recently all backend related code was moved to
+\LUA\ and the code dealing with hyperlinks, widgets and alike is
+now mostly moved away from \TEX. The related cleanup was possible
+because we no longer have to deal with a mix of \DVI\ drivers too.
+\stopitem
+
+\startitem Everything related to structure (which includes
+numbering and multi-pass data like tables of contents and
+registers) is now delegated to \LUA. We move around way more
+information and will extend these mechanisms in the near future.
+\stopitem
+
+\stopitemize
+
+Tracing on Taco's machine has shown that when processing the
+\LUATEX\ reference manual the engine spends about 10\%
+of the time on getting tokens, 15\% on macro expansion, and some
+50\% on \LUA\ (callback interfacing included). Especially the time
+spent by \LUA\ differs per document and garbage collections seems
+to be a bottleneck here. So, let's wrap up how \LUATEX\ performs
+around the time of 0.50.
+
+We use three documents for testing (intermediate) \LUATEX\
+binaries: the reference manual, the history document \quote{mk},
+and the revised metafun manual. The reference manual has a
+\METAPOST\ graphic on each page which is positioned using the
+\CONTEXT\ background layering mechanism. This mechanism is active
+only when backgrounds are defined and has some performance
+consequences for the page builder. However, most time is spent on
+constructing the tables (tabulate) and because these can contain
+paragraphs that can run over multiple pages, constructing a table
+takes a few analysis passes per table plus some so-called
+vsplitting. We load some fonts (including narrow variants) but for
+the rest this document is not that complex. Of course colors are
+used as well as hyperlinks.
+
+The report at the end of the runs looks as follows:

+
+The runtime is influenced by the fact that some startup time and
+font loading takes place. The more pages your document has, the
+less the runtime is influenced by this.
+
+More demanding is the \quote {mk} document (figure~\ref{fig.mk}). Here
+we have many fonts, including some really huge \CJK\ and Arabic ones (and these are
+loaded at several sizes and with different features). The reported
+font load time is large but this is partly due to the fact that on
+my machine for some reason passing the tables to \TEX\ involved a
+lot of pagefaults (we think that the cpu cache is the culprit).
+Older versions of \LUATEX\ didn't have that performance penalty,
+so probably half of the reported font loading time is kind of
+wasted.
+
+The hnode processing time refers mostly to \OPENTYPE\ font
+processing and attribute processing time has to do with backend
+issues (like injecting color directives). The more features you
+enable, the larger these numbers get. The \METAPOST\ font loading
+refers to the punk font instances.

+
+Looking at the Metafun manual one might expect that one needs
+even more time per page but this is not true. We use \OPENTYPE\
+fonts in base mode as we don't use fancy font features (base mode
+uses traditional \TEX\ methods). Most interesting here is the time
+involved in processing \METAPOST\ graphics. There are a lot of
+them (1772) and in addition we have 7 calls to independent
+\CONTEXT\ runs that take one third of the total runtime. About
+half of the runtime involves graphics.

+
+By now it will be clear that processing a document takes a bit of
+time. However, keep in mind that these documents are a bit
+atypical. Although \unknown\ thee average \CONTEXT\ document
+probably uses color (including color spaces that involve resource
+management), and has multiple layers, which involves some testing of
+the about 30 areas that make up the page. And there is the
+user interface that comes with a price.
+
+It might be good to say a bit more about fonts. In \CONTEXT\ we
+use symbolic names and often a chain of them, so the abstract
+\type {SerifBold} resolves to \type {MyNiceFontSerif-Bold} which
+in turn resolves to \type {mnfs-bold.otf}. As \XETEX\ introduced
+lookup by internal (or system) fontname instead of filename,
+\MKII\ also provides that method but \MKIV\ adds some heuristics
+to it. Users can specify font sizes in traditional \TEX\ units but
+also relative to the body font. All this involves a bit of
+expansion (resolving the chain) and parsing (of the
+specification). At each of the levels of name abstraction we can
+have associated parameters, like features, fallbacks and more.
+Although these mechanisms are quite optimized this still comes at a
+performance price.
+
+Also, in the default \MKIV\ font setup we use a couple more
+font variants (as they are available in Latin Modern). We've kept
+definitions sort of dynamic so you can change them and combine
+them in many ways. Definitions are collected in typescripts which
+are filtered. We support multiple mixed font sets which takes a bit
+of time to define but switching is generally fast. Compared to \MKII\
+the model lacks the (font) encoding and case handling code (here
+we gain speed) but it now offers fallback fonts (replaced ranges
+within fonts) and dynamic \OPENTYPE\ font feature switching. When
+used we might lose a bit of processing speed although fewer
+definitions are needed which gets us some back. The font subsystem
+is anyway a factor in the performance, if only because more
+complex scripts or font features demand extensive node list
+parsing.
+
+Processing the \TEX book with \LUATEX\ on Taco's machine takes some
+3.5 seconds in \PDFTEX\ and 5.5 seconds in \LUATEX. This is
+because \LUATEX\ internally is \UNICODE\ and has a larger memory
+space. The few seconds more runtime are consistent with this. One
+of the reasons that The \TEX\ Book processes fast is that the font
+system is not that complex and has hardly any overhead, and an
+efficient output routine is used. The format file is small and the
+macro set is optimal for the task. The coding is rather low level
+so to say (no layers of interfacing). Anyway, 100 pages per second
+is not bad at all and we don't come close with \CONTEXT\ and the
+kind of documents that we produce there.
+
+This made me curious as to how fast really dumb documents could be
+processed. It does not make sense to compare plain \TEX\ and
+\CONTEXT\ because they do different things. Instead I decided to
+look at differences in engines and compare runs with different
+numbers of pages. That way we get an idea of how startup time
+influences overall performance. We look at \PDFTEX, which is
+basically an 8-bit system, \XETEX, which uses external libraries and is
+\UNICODE, and \LUATEX\ which is also \UNICODE, but stays closer to
+traditional \TEX\ but has to check for callbacks.
+
+In our measurement we use a really simple test document as we only
+want to see how the baseline performs. As not much content is
+processed, we focus on loading (startup), the output routine and
+page building, and some basic \PDF\ generation. After all, it's
+often a quick and dirty test that gives users their first
+impression. When looking at the times you need to keep in mind
+that \XETEX\ pipes to \DVIPDFMX\ and can benefit from multiple
+cpu cores. All systems have different memory management and garbage
+collection might influence performance (as demonstrated in an
+earlier chapter of the \quote{mk} document we can trace in detail
+how the runtime is distributed). As terminal output is a significant
+slowdown for \TEX\ we run in batchmode. The test is as follows:
+
+\starttyping
+\starttext
+    \dorecurse{2000}{test\page}
+\stoptext
+\stoptyping
+
+On my laptop (Dell M90 with 2.3Ghz T76000 Core 2 and 4MB memory
+running Vista) I get the following results. The test script ran
+each test set 5~times and we show the fastest run so we kind of
+avoid interference with other processes that take time. In
+practice runtime differs quite a bit for similar runs, depending
+on the system load. The time is in seconds and between parentheses
+the number of pages per seconds is mentioned.

+A test demonstrated that for \LUATEX\ the 30 and 300 page runs
+take 70\% more runtime with 32 bit binaries (recent binaries for
+these engines are available on the \CONTEXT\ wiki \type
+{contextgarden.net}).
+
+When you compare both tables it will be clear that it is
+non|-|trivial to come to conclusions about performances. But one thing
+is clear: \LUATEX\ with \CONTEXT\ \MKIV\ is not performing that
+badly compared to its cousins. The \UNICODE\ engines perform about
+the same and \PDFTEX\ beats them significantly. Okay, I have to
+admit that in the meantime some cleanup of code in \MKIV\ has
+happened and the \LUATEX\ runs benefit from this, but on the other
+hand, the other engines are not hindered by callbacks. As I expect
+to use \MKII\ less frequently optimizing the older code makes no
+sense.
+
+There is not much chance of \LUATEX\ itself becoming faster,
+although a few days before writing this Taco managed to speed up
+font inclusion in the backend code significantly (we're talking
+about half a second to a second for the three documents used
+here). On the contrary, when we open up more mechanisms and have
+upgraded backend code it might actually be a bit slower. On the
+other hand, I expect to be able to clean up some more \CONTEXT\
+code, although we already got rid of some subsystems (like the
+rather flexible (mixed) font encoding, where each language could
+have multiple hyphenation patters, etc.). Also, although initial
+loading of math fonts might take a bit more time (as long as we
+use virtual Latin Modern math), font switching is more efficient
+now due to fewer families. But speedups in the \CONTEXT\ code might
+be compensated for by more advanced mechanisms that call out to \LUA.
+You will be surprised by how much speed can be improved by proper
+document encoding and proper styles. I can try to gain a couple
+more pages per second by more efficient code, but a user's style
+that does an inefficient massive font switch for some 10 words per
+page easily compensates for that.
+
+When processing this 10 page chapter in an editor (Scite) it takes
+some 2.7 seconds between hitting the processing key and the result
+showing up in Acrobat. I can live with that, especially when I
+keep in mind that my next computer will be faster.
+
+This is where we stand now. The three reports shown before give
+you an impression of the impact of \LUATEX\ on \CONTEXT. To what
+extent is this reflected in the code base? We end this chapter
+with showing four tables. The first table shows the number of
+files that make up the core of \CONTEXT\ (modules are excluded).
+The second table shows the accumulated size of these files
+(comments and spacing stripped). The third and fourth table show
+the same information in a different way, just to give you a better
+impression of the relative number of files and sizes. The four
+character tags represent the file groups, so the files have
+names like \type {node-ini.mkiv}, \type {font-otf.lua} and
+\type {supp-box.tex}.
+
+Eventually most \MKII\ files (with the \type {mkii} suffix) and
+\MKIV\ files (with suffix \type {mkiv}) will differ and the number
+of files with the \type {tex} suffix will be fewer. Because they
+are and will be mostly downward compatible, styles and modules
+will be shared as much as possible.

+\chapter{How \LUA\ fits in}
+
+\subject{introduction}
+
+Here I will discuss a few of the experiments that drove the
+development of \LUATEX. It describes the state of affairs around
+the time that we were preparing for \TUG\ 2006. This development
+was pretty demanding for Taco and me but also much fun. We were in
+a kind of permanent Skype chat session, with binaries flowing in
+one direction and \TEX\ and \LUA\ code the other way. By gradually
+replacing (even critical) components of \CONTEXT\ we had a real
+test bed and torture tests helped us to explore and debug at the
+same time. Because Taco uses \LINUX\ as platform and I mostly use
+\MSWINDOWS, we could investigate platform dependent issues
+conveniently. While reading this text, keep in mind that this is
+just the beginning of the game.
+
+I will not provide sample code here. When possible, the \MKIV\
+code transparantly replaces \MKII\ code and users will seldom
+notices that something happens in different way. Of course the
+potential is there and future extensions may be unique to \MKIV.
+
+\subject{compatibility}
+
+The first experiments, already conducted with the experimental
+versions involved runtime conversion of one type of input into
+another. An example of this is the (TI) calculator math input
+handler that converts a rather natural math sequence into \TEX\
+and feeds that back into \TEX. This mechanism eventually will
+evolve into a configurable math input handler. Such applications
+are unique to \MKIV\ code and will not be backported to \MKII. The
+question is where downward compatibility will become a problem. We
+don't expect many problems, apart from occasional bugs that result
+from splitting the code base, mostly because new features will not
+affect older functionality. Because we have to reorganize the code
+base a bit, we also use this opportunity to start making a variant
+of \CONTEXT\ which consists of building blocks: \METATEX. This is
+less interesting for the average user, but may be of interest for
+those using \CONTEXT\ in workflows where only part of the
+functionality is needed.
+
+\subject{metapost}
+
+Of course, when I experiment with such new things, I cannot let
+\METAPOST\ leave untouched. And so, in the early stage of \LUATEX\
+development I decided to play with two \METAPOST\ related
+features: conversion and runtime processing.
+
+Conversion from \METAPOST\ output to \PDF\ is currently done in
+pure \TEX\ code. Apart from convenience, this has the advantage
+that we can let \TEX\ take care of font inclusions. The tricky
+part of this conversion is that \METAPOST\ output has some weird
+aspects, like \DVIPS\ specific linewidth snapping. Another nasty
+element in the conversion is that we need to transform paths when
+pens are used. Anyhow, the converter has reached a rather stable
+state by now.
+
+One of the ideas with \METAPOST\ version 1\high{+} is that we will
+have an alternative output mode. In the perspective of \LUATEX\ it
+makes sense to have a \LUA\ output mode. Whatever converter we
+use, it needs to deal with \METAFUN\ specials. These are
+responsible for special features like transparency, graphic
+inclusion, shading, and more. Currently we misuse colors to signal
+such features, but the new pre|/|post path hooks permit more
+advanced implementations. Experimenting with such new features is
+easier in \LUA\ than in \TEX.
+
+The \MKIV\ converter is a multi||pass converter. First we clean up the
+\METAPOST\ output, next we convert the \POSTSCRIPT\ code into \LUA\
+calls. We assume that this \LUA\ code eventually can be output directly
+from \METAPOST. We then evaluate this converted \LUA\ blob, which results
+in \TEX\ commands. Think of:
+
+\starttyping
+1.2 setlinejoin
+\stoptyping
+
+turned into:
+
+\starttyping
+mp.setlinejoin(1.2)
+\stoptyping
+
+becoming:
+
+\starttyping
+\PDFcode{1.2 j}
+\stoptyping
+
+which is, when the \PDFTEX\ driver is active, equivalent to:
+
+\starttyping
+\pdfliteral{1.2 j}
+\stoptyping
+
+Of course, when paths are involved, more things happen behind the
+scenes, but in the end an \type {mp.path} enters the \LUA\
+machinery.
+
+When the \MKIV\ converter reached a stable state, tests
+demonstrated then the code was upto 20\% slower that the pure
+\TEX\ alternative on average graphics, and but faster when many
+complex path transformations (due to penshapes) need to be done.
+This slowdown was due to the cleanup (using expressions) and
+intermediate conversion. Because Taco develops \LUATEX\ as well as
+maintains and extends \METAPOST, we conducted experiments that
+combine features of these programs. As a result of this, shortcuts
+found their way into the \METAPOST\ output.
+
+\useMPlibrary[mis]
+
+\placefigure
+  []
+  [fig:mptopdf]
+  {converter test figure}
+  {\scale[width=\hsize]{\useMPgraphic{mptopdf-test}}}
+
+Cleaning up the \METAPOST\ output using \LUA\ expressions takes
+relatively much time. However, starting with version 0.970
+\METAPOST\ uses a preamble, which permits not only short commands,
+but also gets rid of the weird linewidth and filldraw related
+\POSTSCRIPT\ constructs. The moderately complex graphic that we
+use for testing (\in {figure} [fig:mptopdf]) takes over 16 seconds
+when converted 250 times. When we enable shortcuts we can avoid
+part of the cleanup and runtime goes down to under 7.5 seconds.
+This is significantly faster than the \MKII\ code. We did experiments
+with simulated \LUA\ output from \METAPOST\ and then the \MKIV\
+converter really flies. The values on Taco's system are given
+between parenthesis.

+\HL
+\stoptabulate
+
+The main reason for the huge difference in the \MKIV\ times is
+that we do a rigourous cleanup of the older \METAPOST\ output
+in order avoid messy the messy (but fast) code that we use in
+the \MKII\ converter. Think of:
+
+\starttyping
+0 0.5 dtransform truncate idtransform setlinewidth pop
+closepath gsave fill grestore stroke
+\stoptyping
+
+In the \MKII\ converter, we push every number or keyword on a
+stack and use keywords as trigger points. In the \MKIV\ code
+we convert the stack based \POSTSCRIPT\ calls to \LUA\
+function calls. Lines as shown are converted to single calls
+first. When \type {prologues} is set to~2, such line no longer
+show up and are replaced by simple calls accompanied by
+definitions in the preamble. Not only that, instead of verbose
+keywords, one or two character shortcuts are used. This means
+that the \MKII\ code can be faster when procsets are used
+because shorter strings end up in the stack and comparison
+happens faster. On the other hand, when no procsets are used,
+the runtime is longer because of the larger preamble.
+
+Because the converter is used outside \CONTEXT\ as well, we
+support all combinations in order not to get error messages, but
+the converter is supposed to work with the following settings:
+
+\starttyping
+prologues := 1 ;
+mpprocset := 1 ;
+\stoptyping
+
+We don't need to set \type {prologues} to~2 (font encodings
+in file) or~3 (also font resources in file). So, in the end, the
+comparison in speed comes down to 8.0 seconds for \MKII\ code and
+7.2 seconds for the \MKIV\ code when using the latest greatest
+\METAPOST. When we simulate \LUA\ output from \METAPOST, we end
+up with 4.2 seconds runtime and when \METAPOST\ could produce the
+converter's \TEX\ commands, we need only 0.3 seconds for embedding
+the 250 instances. This includes \TEX\ taking care of handling the
+specials, some of which demand building moderately complex \PDF\
+data structures.
+
+But, conversion is not the only factor in convenient \METAPOST\
+usage. First of all, runtime \METAPOST\ processing takes time. The
+actual time spent on handling embedded \METAPOST\ graphics is also
+dependent on the speed of starting up \METAPOST, which in turn
+depends on the size of the \TEX\ trees used: the bigger these are,
+the more time \KPSE\ spends on loading the \type {ls-R} databases.
+Eventually this bottleneck may go away when we have \METAPOST\ as
+a library. (In \CONTEXT\ one can also run \METAPOST\ between runs.
+Which method is faster, depends on the amount and complexity of
+the graphics.)
+
+Another factor in dealing with \METAPOST, is the usage of text in
+a graphic (\type {btex}, \type {textext}, etc.). Taco Hoekwater,
+Fabrice Popineau and I did some experiments with a persistent
+\METAPOST\ session in the background in order to simulate a
+library. The results look very promising: the overhead of embedded
+\METAPOST\ graphics goes to nearly zero, especially when we also
+let the parent \TEX\ job handle the typesetting of texts. A side
+effect of these experiments was a new mechanism in \CONTEXT\ (and
+\METAFUN) where \TEX\ did all typesetting of labels, and
+\METAPOST\ only worked with an abstract representation of the
+result. This way we can completely avoid nested \TEX\ runs (the
+ones triggered by \METAPOST). This also works ok in \MKII\ mode.
+
+Using a persistent \METAPOST\ run and piping data into it is not
+the final solution if only because the terminal log becomes messed
+up too much, and also because intercepting errors is real messy.
+In the end we need a proper library approach, but the experiments
+demonstrated that we needed to go this way: handling hundreds of
+complex graphics that hold typeset paragraphs (being slanted and
+rotated and more by \METAPOST), tooks mere seconds compared to
+minutes when using independent \METAPOST\ runs for each job.
+
+\subject{characters}
+
+Because \LUATEX\ is \UTF\ based, we need a different way to deal with
+input encoding. For this purpose there are callbacks that intercept
+the input and convert it as needed. For context this means that the
+regime related modules get a \LUA\ based counterparts. As a prelude to
+advanced character manipulations, we already load extensive unicode
+and conversion tables, with the benefit of being able to handle case
+handling with \LUA.
+
+The character tables are derived from unicode tables and \MKII\
+\CONTEXT\ data files and generated using \MTXTOOLS. The main
+character table is pretty large, and this made us experiment a bit
+with efficiency. It was in this stage that we realized that it
+made sense to use precompiled \LUA\ code (using \type {luac}).
+During format generation we let \CONTEXT\ keep track of used \LUA\
+files and compiled them on the fly. For a production run, the
+compiled files were loaded instead.
+
+Because at that stage \LUATEX\ was already a merge between
+\PDFTEX\ and \ALEPH, we had to deal with pretty large format
+files. About that moment the \CONTEXT\ format with the english
+user interface amounted to:
+
+\starttabulate[|c|c|c|c|c|]
+\NC \bf date   \NC \bf luatex \NC \bf pdftex \NC \bf xetex \NC \bf aleph \NC \NR
+\NC 2006-09-18 \NC 9 552 042  \NC 7 068 643  \NC 8 374 996 \NC 7 942 044 \NC \NR
+\stoptabulate
+
+One reason for the large size of the format file is that the
+memory footprint of a 32 bit \TEX\ is larger than that of good old
+\TEX, even with some of the clever memory allocation techniques as
+used in \LUATEX. After some experiments where size and speed were
+measured Taco decided to compress the format using a level~3 \ZIP\
+compression. This brilliant move lead to the following size:
+
+\starttabulate[|c|c|c|c|c|]
+\NC \bf date   \NC \bf luatex \NC \bf pdftex \NC \bf xetex \NC \bf aleph \NC \NR
+\NC 2006-10-23 \NC 3 135 568  \NC 7 095 775  \NC 8 405 764 \NC 7 973 940 \NC \NR
+\stoptabulate
+
+The first zipped versions were smaller (around 2.3 meg), but in
+the meantime we moved the \LUA\ code into the format and the
+character related tables take some space.
+
+\start \it How stable are the mentioned numbers? Ten months after writing the
+previous text we get the following numbers: \stop
+
+\starttabulate[|c|c|c|c|c|]
+\NC \bf date   \NC \bf luatex \NC \bf pdftex \NC \bf xetex \NC \bf aleph \NC \NR
+\NC 2007-08-16 \NC 5 603 676  \NC 7 505 925  \NC 8 838 538 \NC 8 369 206 \NC \NR
+\stoptabulate
+
+They are all some 400K larger, which is probably the result of changes in
+hyphenation patterns (we now load them all, some several times depending on the
+font encodings used). Also, some extra math support has been brought in the kernel
+and we predefine a few more things. However, \LUATEX's format has become much
+larger! Partly this is the result of more \LUA\ code, especially \OPENTYPE\ font
+handling and attributes related code. The extra \TEX\ code is probably compensated
+by the removal of obsolete (at least for \MKIV) code. However, the significantly
+larger number is mostly there because a different compression algorithm is used:
+speed is now favoured over efficiency.
+
+\subject{debugging}
+
+In the process of experimenting with callbacks I played a bit with
+handling \TEX\ error information. An option is to generate an
+\HTML\ page instead of spitting out the usual blob of into on the
+terminal. In \in {figure} [fig:error] and \in {figure} [fig:debug]
+you can see an example of this.
+
+\placefigure[][fig:error]{An example error screen.}{\externalfigure[mk-error.png][width=\textwidth]}
+\placefigure[][fig:debug]{An example debug screen.}{\externalfigure[mk-debug.png][width=\textwidth]}
+
+Playing with such features gives us an impression of what kind of
+access we need to \TEX's internals. It also formed a starting
+point for conversion routines and a mechanism for embedding \LUA\
+code in \HTML\ pages generated by \CONTEXT.
+
+\subject{file io}
+
+Replacing \TEX's in- and output handling is non||trival. Not only
+is the code quite interwoven in the \WEBC\ source, but there is also
+the \KPSE\ library to deal with. This means that quite some callbacks
+are needed to handle the different types of files. Also, there is output
+to the log and terminal to take care of.
+
+Getting this done took us quite some time and testing and
+debugging was good for some headaches. The mechanisms changed a
+few times, and \TEX\ and \LUA\ code was thrown away as soon as
+better solutions came around. Because we were testing on real
+documents, using a fully loaded \CONTEXT\ we could converge to a
+stable version after a while.
+
+Getting this \IO\ stuff done is tightly related to generating the
+format and starting up \LUATEX. If you want to overload the file
+searching and \IO\ handling, you need overload as soon as possible.
+Because \LUATEX\ is also supposed to work with the existing \KPSE\
+library, we still have that as fallback, but in principle one
+could think of a \KPSE\ free version, in which case the default
+file searching is limited to the local path and memory
+initialization also reverts to the hard coded defaults. A
+complication is that the soure code has \KPSE\ calls and
+references to \KPSE\ variables all over the place, so occasionally
+we run into interesting bugs.
+
+Anyhow, while Taco hacked his way around the code, I converted my
+existing \RUBY\ based \KPSE\ variant into \LUA\ and started working
+from that point. The advantage of having our own \IO\ handler is
+that we can go beyond \KPSE. For instance, since \LUATEX\ has,
+among a few others, the \ZIP\ libraries linked in, we can read from
+\ZIP\ files, and keep all \TEX\ related files in \TDS\ compliant \ZIP\
+files as well. This means that one can say:
+
+\starttyping
+\input zip:///somezipfile.zip?name=/somepath/somefile.tex
+\stoptyping
+
+and use similar references to access files. Of course we had to make
+sure that \KPSE\ like searching in the \TDS\ (standardized \TEX\ trees)
+works smoothly. There are plans to link the curl library into \LUATEX,
+so that we can go beyong this and access repositories.
+
+Of course, in order to be more or less \KPSE\ and \WEBC\
+compliant, we also need to support this paranoid file handling, so
+we provide mechanisms for that as well. In addition, we provide
+ways to create sandboxes for system calls.
+
+Getting to intercept all log output (well, most log output) was
+a problem in itself. For this I used a (preliminary) \XML\ based
+log format, which will make log parsing easier. Because we have
+full control over file searching, opening and closing, we can
+also provide more information about what files are loaded. For
+instance we can now easily trace what \TFM\ files \TEX\ reads.
+
+Implementing additional methods for locating and opening files is
+not that complex because the library that ships with \CONTEXT\
+is already prepared for this. For instance, implementing support
+for:
+
+\starttyping
+\input http://www.someplace.org/somepath/somefile.tex
+\stoptyping
+
+involved a few lines of code, most of which deals with caching the
+files. Because we overload the whole \IO\ handling, this means that
+the following works ok:
+
+% \bgroup \loggingall
+
+\startbuffer
+\placefigure
+  [][]
+  {http handling}
+  {\externalfigure
+     [http://www.pragma-ade.com/show-gra.pdf]
+     [page=1,width=\textwidth]}
+\stopbuffer
+
+\typebuffer \ifx\ctxlua \undefined \else \getbuffer \fi
+
+% \egroup
+
+Other protocols, like \FTP\ are also supported, so one can say:
+
+\starttyping
+\typefile {ftp://anonymous:@ctan.org/tex-archive/systems\
+    /knuth/lib/plain.tex}
+\stoptyping
+
+On the agenda is playing with database, but by the time that we enter
+that stage linking the \type {curl} libraries into \LUATEX\ should
+have taken place.
+
+\subject{verbatim}
+
+The advance of \LUATEX\ also permitted us to play with a long
+standing wish of catcode tables, a mechanism to quickly switch
+between different ways of treating input characters. An example of
+a place where such changes take place is verbatim (and in \CONTEXT\
+also when dealing with \XML\ input).
+
+We already had encountered the phenomena that when piping back
+results from \LUA\ to \TEX, we needed to take care of catcodes so
+that \TEX\ would see the input as we wished. Earlier experiments
+with applying \type {\scantokens} to a result and thereby
+interpreting the result conforming the current catcode regime was
+not sufficient or at least not handy enough, especially in the
+perspective of fully expandable \LUA\ results. To be honest, the \type
+{\scantokens} command was rather useless for this purposes due to its
+pseudo file nature and its end||of||file handling but in \LUATEX\
+we now have a convenient \type {\scantextokens} which has no side
+effects.
+
+Once catcode tables were in place, and the relevant \CONTEXT\ code
+adapted, I could start playing with one of the trickier parts of
+\TEX\ programming: typesetting \TEX\ using \TEX, or verbatim.
+Because in \CONTEXT\ verbatim is also related to buffering and
+pretty printing, all these mechanism were handled at once. It
+proved to be a pretty good testcase for writing \LUA\ results back
+to \TEX, because anything you can imagine can and will interfere
+(line endings, catcode changes, looking ahead for arguments, etc).
+This is one of the areas where \MKIV\ code will make things look
+more clean and understandable, especially because we could move
+all kind of postprocessing (needed for pretty printing, i.e.\
+syntax highlighting) to \LUA. Interesting is that the resulting
+code is not beforehand faster.
+
+Pretty printing 1000 small (one line) buffers and 5000 simple
+\type {\type} commands perform as follows:
+
+\starttabulate[|l|c|c|c|c|]
+\NC        \NC \TEX\ normal \NC \TEX\ pretty \NC \LUA\ normal \NC \LUA\ pretty \NC \NR
+\NC buffer \NC 2.5 (2.35)   \NC ~4.5 (3.05)  \NC 2.2 (1.8)    \NC ~2.5 (2.0)   \NC \NR
+\NC inline \NC 7.7 (4.90)   \NC 11.5 (7.25)  \NC 9.1 (6.3)    \NC 10.9 (7.5)   \NC \NR
+\stoptabulate
+
+Between braces the runtime on Taco's more modern machine is shown.
+It's not that easy to draw conclusions from this because \TEX\
+uses files for buffers and with \LUA\ we store buffers in memory.
+For inline verbatim, \LUA\ call's bring some overhead, but with
+more complex content, this becomes less noticable. Also, the \LUA\
+code is probably less optimized than the \TEX\ code, and we don't
+know yet what benefits a Just In Time \LUA\ compiler will bring.
+
+\subject{xml}
+
+Interesting is that the first experiments with \XML\ processing
+don't show the expected gain in speed. This is due to the fact
+that the \CONTEXT\ \XML\ parser is highly optimized. However, if
+we want to load a whole \XML\ file, for instance the formal
+\CONTEXT\ interface specification \type {cont-en.xml}, then we can
+bring down loading time (as well as \TEX\ memory usage) down from
+multiple seconds to a blink of the eyes. Experiments with internal
+mappings and manipulations demonstrated that we may not so much
+need an alternative for the current parser, but can add additional,
+special purpose ones.
+
+We may consider linking \XSLTPROC\ into \LUATEX, but this is yet
+undecided. After all, the problem of typesetting does not really
+change, so we may as well keep the process of manipulating and
+typesetting separated.
+
+\subject{multipass data}
+
+Those who know \CONTEXT\ a bit will know that it may need multiple
+passes to typeset a document. \CONTEXT\ not only keeps track of
+index entries, list entries, cross references, but also optimizes
+some of the output based on information gathered in previous
+passes. Especially so called two||pass data and positional
+information puts some demands on memory and runtime. Two||pass
+data is collapsed in lists because otherwise we would run out of
+memory (at least this was true years ago when these mechanisms
+were introduced). Positional information is stored in hashes and
+has always put a bit of a burden on the size of a so called
+utility file (\CONTEXT\ stores all information in one auxiliary
+file).
+
+These two datatypes were the first we moved to a \LUA\ auxiliary
+file and eventually all information will move there. The advantage
+is that we can use efficient hashes (without limitations) and only
+need to run over the file once. And \LUA\ is incredibly fast in
+loading the tables where we keep track of these things. For
+instance, a test file storing and reading 10.000 complex positions
+takes 3.2 seconds runtime with \LUATEX\ but 8.7 seconds with
+traditional \PDFTEX. Imagine what this will save when dealing with
+huge files (400 page 300 Meg files) that need three or more passes
+to be typeset. And, now we can without problems bump position
+tracking to milions of positions.
+
+\subject{resources}
+
+Finding files is somewhat tricky and has a history in the \TEX\
+community and its distributions. For reasons of packaging and
+searching files are organized in a tree and there are rules for
+locating files of given types in this tree. When we say
+
+\starttyping
+\input blabla.tex
+\stoptyping
+
+\TEX\ will look for this file by consulting the path specification
+associated with the filetype. When we say
+
+\starttyping
+\input blabla
+\stoptyping
+
+\TEX\ will add the \type {.tex} suffix itself. Most other filetypes
+are not seen by users but are dealt with in a similar way internally.
+
+As mentioned before, we support reading from other resources than
+the standard file system, for instance we can input files from
+websites or read from \ZIP\ archives. Although this works quite well,
+we need to keep in mind that there are some conflicting interests:
+structured search based on type related specifications versus more
+or less explicit requests.
+
+\starttyping
+\input zip:///archive.zip?name=blabla.tex
+\input zip:///archive.zip?name=/somepath/blabla.tex
+\stoptyping
+
+Here we need to be rather precise in defining the file location. We can
+of course build rather complex mechanisms for locating files here, but
+at some point that may backfire and result in unwanted matches.
+
+If you want to treat a \ZIP\ archive as a \TEX\ tree, then you need
+to register the file:
+
+\starttyping
+\usezipfile[archive.zip]
+\usezipfile[tex.zip][texmf-local]
+\usezipfile[tex.zip?tree=texmf-local]
+\stoptyping
+
+The first variant registers all files in the archive, but the
+next two are equivalent and only register a subtree. The registered
+tree is prepended to the \type {TEXMF} specification and thereby
+may overload existing trees.
+
+If an acrhive is not a real \TEX\ tree, you can access files anywhere
+in the tree by using wildcards
+
+\starttyping
+\input */blabla.tex
+\input */somepath/blabla.tex
+\stoptyping
+
+These mechanisms evolve over time and it may take a while before they
+stabelize. For instance, the syntax for the \ZIP\ inclusion has been
+adapted more than a year after this chapter was written (which is
+why this section is added).

+\chapter{Unicode math}
+
+{\em I assume that the reader is somewhat familiar with math in
+\TEX. Although in \CONTEXT\ we try to support the concepts and
+symbols used in the \TEX\ community we have our own way of
+implementing math. The fact that \CONTEXT\ is not used extensively
+for conventional math journals permits us to rigourously
+re|-|implement mechanisms. Of course the user interfaces mostly
+remain the same.}
+
+\subject{introduction}
+
+The \LUATEX\ project entered a new stage when end of 2008 and
+beginning of 2009 math got opened up. Although \TEX\ can handle
+math pretty good we had a few wishes that we hoped to fulfill in
+the process. That \TEX's math machinery is a rather independent
+subsystem is reflected in the fact that after parsing there is an
+intermediate list of so called noads (math elements), which then
+gets converted into a node list (glyphs, kerns, penalties, glue and
+more). This conversion can be intercepted by a callback and a
+macro package can do whatever it likes with the list of noads as
+long as it returns a proper list.
+
+Of course \CONTEXT\ does support math and that is visible in its
+code base:
+
+\startitemize
+
+\item Due to the fact that we need to be able to switch to
+alternative styles the font system is quite complex and in
+\CONTEXT\ \MKII\ math font definitions (and changes) are good for
+50\% of the time involved. In \MKIV\ we can use a more efficient
+model.
+
+\item Because some usage of \CONTEXT\ demands the mix of several
+completely different encoded math fonts there is a dedicated math
+encoding subsystem in \MKII. In \MKIV\ we will use \UNICODE\
+exclusively.
+
+\item Some constructs (and symbols) are implemented in a way that
+we find suboptimal. In the perspective of \UNICODE\ in \MKIV\ we
+aim at all symbols being real characters. This is possible because
+all important constructs (like roots, accents and delimiters) are
+supported by the engine.
+
+\item In order to fit vertical spacing around math (think for
+instance of typesetting on a grid) in \MKII\ we have ended up with
+rather messy and suboptimal code. \footnote {This is because
+spacing before and after formulas has to cooperate with spacing of
+structural components that surround it.} The expectation is that
+we can improve that.
+
+\stopitemize
+
+In the following sections I will discuss a few of the
+implementation details of the font related issues in \MKIV. Of
+course a few years from now the actual solutions we implemented
+might look different but the principles remain the same. Also, as
+with other components of \LUATEX\ Taco and I worked in parallel on
+the code and its usage, which made both our tasks easier.
+
+\subject{transition}
+
+In \TEX, math typesetting uses a special concept called families.
+Each math component (number, letter, symbol, etc) is member of a
+family. Because we have three sizes (text, script and
+scriptscript) this results in a family||size matrix of defined
+fonts. Because the number of glyphs in a font was limited to 256,
+in practice it meant that we had quite some font definitions. The
+minimum number of families was~4 (roman, italic, symbol, and
+extension) but in practice several more could be active (sans,
+bold, mono|-|spaced, more symbols, etc.) for specific alphabets or
+extra symbols (for instance \AMS\ set A and B). The total number
+of families in traditional \TEX\ is limited to 16, and one easily
+hits this maximum. In that case, some 16 times 3 fonts are defined
+for one size of which in practice only a few are really used in the
+typesetting.
+
+A potential source of confusion is bold math. Bold in math can
+either mean having some bold letters, or having the whole formula
+in bold. In practice this means that for a complete bold formula
+one has to define the whole lot using bold fonts. A complication
+is that the math symbols (etc) are kind of bound to families and
+so we end up with either redefining symbols, or reusing the
+families (which is easier and faster). In any case there is a
+performance issue involved due to the rather massive switch from
+normal to bold.
+
+In \UNICODE\ all alphabets that make sense as well as all math
+symbols are part of the definition although unfortunately some
+alphabets have their letters spread over the \UNICODE\ vector and
+not in a range (like blackboard). This forces all applications
+that want to support math to implement similar hacks to deal with
+it.
+
+In \MKIV\ we will assume that we have \UNICODE\ aware math fonts,
+like \OPENTYPE. The font that sets the standard is Microsoft
+Cambria. The upcoming (I'm writing this in January 2009) \TEX Gyre
+fonts will be compliant to this standard but they're not yet there
+and so we have a problem. The way out is to define virtual fonts
+and now that \LUATEX\ math is extended to cover all of \UNICODE\
+as well as provides access to the (intermediate) math lists this
+has become feasible. This also permits us to test \LUATEX\
+with both Cambria and Latin Modern Virtual Math.
+
+The advantage is that we can stick to just one family for all
+shapes which simplifies the underlying \TEX\ code enormously.
+First of all we need to define way less fonts (which is partially
+compensated by loading them as part of the virtual font) and all
+math aspects can now be dealt with using the character data
+tables.
+
+One tricky aspect of the new approach is that the Latin Modern
+fonts have design sizes, so we have to define several virtual
+fonts. On the other hand, fonts like Cambria have alternative
+script and scriptscript shapes which is controlled by the \type
+{ssty} feature, a gsub alternate that provides some alternative
+sizes for a couple of hundred characters that matter.
+
+\starttabulate[|l|l|l|]
+\NC text         \NC \type {lmmi12 at 12pt} \NC \type {cambria at 12pt with ssty=no} \NC \NR
+\NC script       \NC \type {lmmi8  at  8pt} \NC \type {cambria at  8pt with ssty=1}  \NC \NR
+\NC scriptscript \NC \type {lmmi6  at  6pt} \NC \type {cambria at  6pt with ssty=2}  \NC \NR
+\stoptabulate
+
+So Cambria not so much has design sizes but shapes optimized
+relative to the text variant: in the following example we see text
+in red, script in green and scriptscript in blue.
+
+\startbuffer
+\definefontfeature[math][analyze=false,script=math,language=dflt]
+
+\definefontfeature[text]        [math][ssty=no]
+\definefontfeature[script]      [math][ssty=1]
+\definefontfeature[scriptscript][math][ssty=2]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Let us first look at Cambria:
+
+\startbuffer
+\startoverlay
+    {\definedfont[name:cambriamath*scriptscript at 150pt]\mkblue  X}
+    {\definedfont[name:cambriamath*script       at 150pt]\mkgreen X}
+    {\definedfont[name:cambriamath*text         at 150pt]\mkred   X}
+\stopoverlay
+\stopbuffer
+
+\typebuffer \startlinecorrection \getbuffer \stoplinecorrection
+
+When we compare them scaled down as happens in real script and
+scriptscript we get:
+
+\startbuffer
+\startoverlay
+    {\definedfont[name:cambriamath*scriptscript at 120pt]\mkblue  X}
+    {\definedfont[name:cambriamath*script       at  80pt]\mkgreen X}
+    {\definedfont[name:cambriamath*text         at  60pt]\mkred   X}
+\stopoverlay
+\stopbuffer
+
+\typebuffer \startlinecorrection \getbuffer \stoplinecorrection
+
+Next we see (scaled) Latin Modern:
+
+\startbuffer
+\startoverlay
+    {\definedfont[LMRoman8-Regular  at 150pt]\mkblue  X}
+    {\definedfont[LMRoman10-Regular at 150pt]\mkgreen X}
+    {\definedfont[LMRoman12-Regular at 150pt]\mkred   X}
+\stopoverlay
+\stopbuffer
+
+\typebuffer \startlinecorrection \getbuffer \stoplinecorrection
+
+In practice we will see:
+
+\startbuffer
+\startoverlay
+    {\definedfont[LMRoman8-Regular  at 120pt]\mkblue  X}
+    {\definedfont[LMRoman10-Regular at  80pt]\mkgreen X}
+    {\definedfont[LMRoman12-Regular at  60pt]\mkred   X}
+\stopoverlay
+\stopbuffer
+
+\typebuffer \startlinecorrection \getbuffer \stoplinecorrection
+
+Both methods probably work out well although you need to keep in
+mind that the \OPENTYPE\ \type {ssty} feature is not so much a
+design size related feature.
+
+An \OPENTYPE\ font can have a specification for the script and
+scriptscript size. By default we listen to this specification instead
+of the one imposed by the bodyfont environment. When you turn on
+tracing
+
+\starttyping
+\enabletrackers[otf.math]
+\stoptyping
+
+you will get messages like:
+
+\starttyping
+asked scriptscript size: 458752, used: 471859.2 (102.86 %)
+asked script size: 589824, used: 574095.36 (97.33 %)
+\stoptyping
+
+The differences between the defaults and the font recommendations
+are not that large so by default we listen to the font specification.

+In this overlay the white text is scaled according to the
+specification in the font, while the red text is scaled according
+to the bodyfont environment (12/7/5 points).
+
+\subject{going virtual}
+
+The number of math fonts (used) in the \TEX\ community is
+relatively small and of those only Latin Modern (which builds upon
+Computer Modern) has design sizes. This means that the amount of
+\UNICODE\ compliant virtual math fonts that we have to make is not
+that large. We could have used an already present virtual
+composition mechanism but instead we made a handy helper function
+that does a more efficient job. This means that a definition looks
+(a bit simplified) as follows:
+
+\starttyping
+mathematics.make_font ( "lmroman10-math", {
+  { name="lmroman10-regular", features="virtualmath", main=true },
+  { name="lmmi10", vector="tex-mi", skewchar=0x7F },
+  { name="lmsy10", vector="tex-sy", skewchar=0x30, parameters=true } ,
+  { name="lmex10", vector="tex-ex", extension=true } ,
+  { name="msam10", vector="tex-ma" },
+  { name="msbm10", vector="tex-mb" },
+  { name="lmroman10-bold", "tex-bf" } ,
+  { name="lmmib10", vector="tex-bi", skewchar=0x7F } ,
+  { name="lmsans10-regular", vector="tex-ss", optional=true },
+  { name="lmmono10-regular", vector="tex-tt", optional=true },
+} )
+\stoptyping
+
+For the \TEX Gyre Pagella it looks this way:
+
+\starttyping
+mathematics.make_font ( "px-math", {
+  { name="texgyrepagella-regular", features="virtualmath", main=true },
+  { name="pxr", vector="tex-mr" } ,
+  { name="pxmi", vector="tex-mi", skewchar=0x7F },
+  { name="pxsy", vector="tex-sy", skewchar=0x30, parameters=true } ,
+  { name="pxex", vector="tex-ex", extension=true } ,
+  { name="pxsya", vector="tex-ma" },
+  { name="pxsyb", vector="tex-mb" },
+} )
+\stoptyping
+
+As you can see, it is possible to add alphabets, given that there is
+a suitable vector that maps glyph indices onto \UNICODE s. It is good
+to know that this function only defines the way such a font is
+constructed. The actual construction is delayed till the font is
+needed.
+
+Such a virtual font is used in typescripts (the building blocks of
+typeface definitions in \CONTEXT) as follows:
+
+\starttyping
+\starttypescript [math] [palatino] [name]
+  \definefontsynonym [MathRoman] [pxmath@px-math]
+  \loadmapfile[original-youngryu-px.map]
+\stoptypescript
+\stoptyping
+
+If you're familiar with the way fonts are defined in \CONTEXT, you will
+notice that we no longer need to define MathItalic, MathSymbol and
+additional symbol fonts. Of course users don't have to deal with
+these issues themselves. The \type {@} triggers the virtual
+font builder.
+
+You can imagine that in \MKII\ switching to another font style or size
+involves initializing (or at least checking) involves some 30 to 40
+font definitions when it comes to math (the number of used
+families times 3, the number o fmath sizes.). And even if we take
+into account that fonts are loaded only once, this checking and
+enabling takes time. Keep in mind that in \CONTEXT\ we can have
+several math font sets active in one document which comes at a
+price.
+
+In \MKIV\ we use one family (at three sizes). Of course we need to
+load the font (and more than one in the case of virtual variants)
+but when switching bodyfont sizes we only need to enable one
+(already defined) math font. And that really saves time. This is
+one of the areas where we gain back time that we loose elsewhere
+by extending core functionality using \LUA\ (like \OPENTYPE\
+support).
+
+\subject{dimensions}
+
+By setting font related dimensions you can control the way \TEX\
+positions math elements relative to each other. Math fonts have a
+few more dimensions than regular text fonts. But \OPENTYPE\ math
+fonts like Cambria have quite some more. There is a nice booklet
+published by Microsoft, \quote {Mathematical Typesetting}, where
+dealing with math is discussed in the perspective of their word
+processor and \TEX. In the booklet some of the parameters are
+discussed and since many of them are rather special it makes no
+sense (yet) to elaborate on them here. \footnote {Googling on
+\quote {Ulrich Vieth}, \quote {TeX} and \quote {conferences} might
+give you some hits on articles on these matters.} Figuring out
+their meaning was quite a challenge.
+
+I am the first to admit that the current code in \MKIV\ that deals
+with math parameters is somewhat messy. There are several reasons
+for this:
+
+\startitemize[packed]
+\item We can pass parameters as \type {MathConstants} table in the
+      \TFM\ table that we pass to the core engine.
+\item We can use some named parameters, like \type {x_height} and
+      pass those in the \type {parameters} table.
+\item We can use the traditional font dimension numbers in the
+      \type {parameters} table, but since they overlap for symbol and
+      extensible fonts, that is asking for troubles.
+\stopitemize
+
+Because in \MKIV\ we create virtual fonts at run|-|time and use just
+one family, we fill the \type {MathConstants} table for
+traditional fonts as well. Future versions may use the upcoming
+mechanisms of font parameter sets at the macro level. These can be
+defined for each of the sizes (display, text, script and
+scriptscript, and the last three in cramped form as well) but
+since a font only carries one set, we currently use a compromise.
+
+\subject{tracing}
+
+One of the nice aspects of the opened up math machinery is that it
+permits us to get a more detailed look at what happens. It also
+fits nicely in the way we always want to visualize things in
+\CONTEXT\ using color, although most users are probably unaware of
+many such features because they don't need them as I do.

+
+This tracker option colors characters depending on their nature and the
+fact that they are remapped. The tracker also was handy during development
+of \LUATEX\ especially for checking if attributes migrated right in
+constructed symbols.
+
+For over a year I had been using a partial \UNICODE\ math
+implementation in some projects but for serious math the vectors
+needed to be completed. In order to help the \quote {math
+department} of the \CONTEXT\ development team (Aditya Mahajan,
+Mojca Miklavec, Taco Hoekwater and myself) we have some extra
+tracing options, like
+
+\startbuffer
+\showmathfontcharacters[list=0x0007B]
+\stopbuffer
+
+\typebuffer
+
+\start \blank \getbuffer \blank \stop
+
+The simple variant with no arguments would have extended this
+document with many pages of such descriptions.
+
+Another handy command (defined in module \type{fnt-25}) is the following:
+
+\starttyping
+\ShowCompleteFont{name:cambria}{9pt}{1}
+\ShowCompleteFont{dummy@lmroman10-math}{10pt}{1}
+\stoptyping
+
+This will for instance for Cambria generate between 50 and 100
+pages of character tables.
+

+$\mathscript abc IRZ \mathfraktur abc IRZ %
+  \mathblackboard abc IRZ \ss abc IRZ 123$
+\stopbuffer
+
+If you look at the following samples you can imagine how coloring
+the characters and replacements helped figuring out the alphabets
+We use the following input (stored in a buffer):
+
+\typebuffer [mathtest]
+
+For testing Cambria we say:
+
+\starttyping
+\usetypescript[cambria]
+\switchtobodyfont[cambria,11pt]
+\enabletrackers[math.analyzing]
+\getbuffer[mathtest] % the input shown before
+\disabletrackers[math.analyzing]
+\stoptyping
+
+And we get:
+
+\usetypescript[cambria] % global
+
+\startlines
+\switchtobodyfont[cambria,10pt]
+\enabletrackers[math.analyzing]
+\getbuffer[mathtest] % the input shown before
+\disabletrackers[math.analyzing]
+\stoplines
+
+For the virtualized Latin Modern we say:
+
+\starttyping
+\usetypescript[modern]
+\switchtobodyfont[modern,11pt]
+\enabletrackers[math.analyzing]
+\getbuffer[mathtest] % the input shown before
+\disabletrackers[math.analyzing]
+\stoptyping
+
+This gives:
+
+\usetypescript[modern] % global
+
+\startlines
+\switchtobodyfont[modern,11pt]
+\enabletrackers[math.analyzing]
+\getbuffer[mathtest]
+\disabletrackers[math.analyzing]
+\stoplines
+
+These two samples demonstrate that Cambria has a rather complete
+repertoire of shapes which is no surprise because it is a recent
+font that also serves as a showcase for \UNICODE\ and \OPENTYPE\
+driven math.
+
+Commands like \type {\mathscript} sets an attribute. When we post|-|process
+the noad list and encounter this attribute, we remap the characters to
+the desired variant. Of course this happens selectively. So, a capital~A
+(\type {0x0041}) becomes a capital script~A (\type {0x1D49C}). Of course
+this solution is rather \CONTEXT\ specific and there are other ways to
+achieve the same goal (like using more families and switching family).
+
+\subject{special cases}
+
+Because we now are operating in the \UNICODE\ domain, we run into
+problems if we keep defining some of the math symbols in the
+traditional \TEX\ way. Even with the \AMS\ fonts available we
+still end up with some characters that are represented by
+combining others. Take for instance $\neq$ which is composed of
+two characters. Because in \MKIV\ we want to have all
+characters in their pure form we use a virtual replacement for
+them. In \MKIV\ speak it looks like this:
+
+\starttyping
+local function negate(main,unicode,basecode)
+    local characters = main.characters
+    local basechar = characters[basecode]
+    local ht, wd = basechar.height, basechar.width
+    characters[unicode] = {
+        width    = wd,
+        height   = ht,
+        depth    = basechar.depth,
+        italic   = basechar.italic,
+        kerns    = basechar.kerns,
+        commands = {
+            { "slot", 1, basecode },
+            { "push" },
+            { "down",    ht/5},
+            { "right", - wd/2},
+            { "slot", 1, 0x2215 },
+            { "pop" },
+        }
+    }
+end
+\stoptyping
+
+In case you're curious, there are indeed kerns, in this case the
+kerns with the Greek Delta.
+
+Another thing we need to handle is positioning of accents on top
+of slanted (italic) shapes. For this \TEX\ uses a special
+character in its fonts (set with \type{\skewchar}). Any character
+can have in its kerning table a kern towards this special
+character. From this kern we
+can calculate the \type {top_accent} variable that we can pass for
+each character. This variable lives at the same level as \type
+{width}, \type {height}, \type {depth} and \type {italic} and is
+calculated as: $w/2 + k$, so it defines the horizontal anchor. A
+nice side effect is that (in the \CONTEXT\ font management
+subsystem) this saves us passing information associated with
+specific fonts such as the skew character.
+
+A couple of concepts are unique to \TEX, like having \type {\hat}
+and \type {\widehat} where the wide one has sizes. In \OPENTYPE\ and
+\UNICODE\ we don't have this distinction so we need special
+trickery to simulate this. We do so by adding extra code points in
+a private \UNICODE\ space which in return results in them being
+defined automatically and the relevant first size variant being
+used for \type {\hat}. For some users this might still be too wide
+but at least it's better than a wrongly positioned \ASCII\ variant.
+In the future we might use this private space for similar cases.
+
+Arrows, horizontal extenders and radicals also fall in the
+category \quote {troublesome} if only because they use special
+dimensions to get the desired effect. Fortunately \OPENTYPE\ math
+is modeled after \TEX, so in \LUATEX\ we introduce a couple
+of new constructs to deal with this. One such simplification at
+the macro level is in the definition of \type {\root}. Here we use
+the new \type {\Uroot} primitive. The placement related parameters
+are those used by traditional \TEX, but when they are available the
+\OPENTYPE\ parameters are applied. The simplified
+plain definitions are now:
+
+\starttyping
+\def\rootradical{\Uroot 0 "221A }
+
+\def\root#1\of{\rootradical{#1}}
+
+\def\sqrt{\rootradical{}}
+\stoptyping
+
+The successive sizes of the root will be taken from the font in the
+same way as traditional \TEX\ does it. In that sense \LUATEX\ is no
+doing anything differently, it only has more parameters to control
+the process. The definition of \type {\sqrt} in \CONTEXT\ permits
+an optional first argument that sets the degree.
+
+\startbuffer
+\showmathfontcharacters[list=0x221A]
+\stopbuffer
+
+\start \blank \getbuffer \blank \stop
+
+Note that we've collected all characters in family~0 (simply
+because that is what \TEX\ defaults characters to) and that we use
+the formal \UNICODE\ slots. When we use the Latin Modern fonts we
+just remap traditional slots to the right ones.
+
+Another neat trick is used when users choose among the bigger variants
+of some characters. The traditional approach is to create a box of a
+certain size and create a fake delimited variant which is then used.
+
+\starttyping
+\definemathcommand [big]  {\choosemathbig\plusone  }
+\definemathcommand [Big]  {\choosemathbig\plustwo  }
+\definemathcommand [bigg] {\choosemathbig\plusthree}
+\definemathcommand [Bigg] {\choosemathbig\plusfour }
+\stoptyping
+
+Of course this can become a primitive operation and we might decide
+to add such a primitive later on so we won't bother you with more
+details.
+
+Attributes are also used to make live easier for authors who have
+to enter lots of pairs. Compare:
+
+\startbuffer
+\setupmathematics[autopunctuation=no]
+
+$ (a,b) = (1.20,3.40) $
+\stopbuffer
+
+\typebuffer \begingroup \getbuffer \endgroup
+
+with:
+
+\startbuffer
+\setupmathematics[autopunctuation=yes]
+
+$ (a,b) = (1.20,3.40) $
+\stopbuffer
+
+\typebuffer \begingroup \getbuffer \endgroup
+
+So we don't need to use this any more:
+
+\starttyping
+$ (a{,}b) = (1{.}20{,}3{.}40) $
+\stoptyping
+
+Features like this are implemented on top of an experimental math
+manipulation framework that is part of \MKIV. When the math
+font system is stable we will rework the rest of math support
+and implement additional manipulating frameworks.
+
+\subject{control}
+
+As with all other character related issues, in \MKIV\ everything
+is driven by a character table (consider it a database).
+Quite some effort went into getting that one right and although by
+now math is represented well, more data will be added in due time.
+
+In \MKIV\ we no longer have huge lists of \TEX\ definitions for
+math related symbols. Everything is initialized using the mentioned
+table: normal symbols, delimiters, radicals, whether or not with name.
+Take for instance the square root:
+
+\start \blank \showmathfontcharacters[list=0x221A] \blank \stop
+
+
+Its entry is:
+
+\starttyping
+[0x221A] = {
+    adobename = "radical",
+    category = "sm",
+    cjkwd = "a",
+    description = "SQUARE ROOT",
+    direction = "on",
+    linebreak = "ai",
+    mathclass = "radical",
+    mathname = "surd",
+    unicodeslot = 0x221A,
+}
+\stoptyping
+
+The fraction symbol also comes in sizes. This symbol is not to be
+confused with the negation symbol \type {0x2215}, which in \TEX\ is
+known as \type {\not}).
+
+\start \blank \showmathfontcharacters[list=0x2044] \blank \stop
+
+\starttyping
+[0x2044] = {
+    adobename = "fraction",
+    category = "sm",
+    contextname = "textfraction",
+    description = "FRACTION SLASH",
+    direction = "cs",
+    linebreak = "is",
+    mathspec = {
+        { class = "binary", name = "slash" },
+        { class = "close", name = "solidus" },
+    },
+    unicodeslot = 0x2044,
+}
+\stoptyping
+
+However, since most users don't have this symbol visualized in
+their word processor, they expect the same behaviour from the
+regular slash. This is why we find a reference to the real symbol
+in its definition.
+
+\start \blank \showmathfontcharacters[list=0x002F] \blank \stop
+
+The definition is:
+
+\starttyping
+[0x002F] = {
+    adobename = "slash",
+    category = "po",
+    cjkwd = "na",
+    contextname = "textslash",
+    description = "SOLIDUS",
+    direction = "cs",
+    linebreak = "sy",
+    mathsymbol = 0x2044,
+    unicodeslot = 0x002F,
+}
+\stoptyping
+
+One problem left is that currently we have only one class per
+character (apart from the delimiter and radical usage which have
+their own definitions). Future releases of \CONTEXT\ will provide
+support for math dictionaries (as in \OPENMATH\ and \MATHML~3). At
+that point we will also have a \type {mathdict} entry.
+
+There is another issue with character mappings, one that will
+seldom reveal itself to the user, but might confuse macro writers
+when they see an error message.
+
+In traditional \TEX, and therefore also in the Latin Modern fonts,
+a chain from small to large character goes in two steps: the
+normal size is taken from one family and the larger variants from
+another. The larger variant then has a pointer to an even larger
+one and so on, until there is no larger variant or an extensible
+recipe is found. The default family is number~0. It is for this
+reason that some of the definition primitives expect a small and
+large family part.
+
+However, in order to support \OPENTYPE\ in \LUATEX\ the
+alternative method no longer assumes this split. After all, we no
+longer have a situation where the 256 limit forces us to take the
+smaller variant from one font and the larger sequence from another
+(so we need two family||slot pairs where each family eventually
+resolves to a font).
+
+It is for that reason that the new \type {\U...} primitives expect
+only one family specification: the small symbol, which then has a
+pointer to a larger variant when applicable. However deep down in
+the engine, there is still support for the multiple family
+solution (after all, we don't want to drop compatibility). As a
+result, in error messages you can still find references
+(defaulting to~0) to large specifications, even if you don't use
+them. In that case you can simply ignore the large symbol (0,0),
+since it is not used when the small symbol provides a link.
+
+\subject{extensibles}
+
+In \TEX\ fences can be told to become larger automatically. In
+traditional \TEX\ a character can have a linked list of next
+larger shapes ending in a description of how to compose even
+larger variants.
+
+A parenthesis in Cambria has the following list:
+
+\start
+    \switchtobodyfont[cambria,10pt]
+    \showmathfontcharacters[list=0x00028]
+\stop
+
+In Latin Modern we have:
+
+\start
+    \switchtobodyfont[modern,10pt]
+    \showmathfontcharacters[list=0x00028]
+\stop
+
+Of course \LUATEX\ is downward compatible with respect to this
+feature, but the internal representation is now closer to what
+\OPENTYPE\ math provides (which is not that far from how \TEX\
+works simply because it's inspired by \TEX). Because Cambria has
+different parameters we get slightly different results. In the
+following list of pairs, you see Cambria on the left and Latin
+Modern on the right.
+Both start with stepwise larger shapes, followed by a more gradual
+growth. The thresholds for a next step are driven by parameters
+set in the \OPENTYPE\ font or by \TEX's default.

+}
+\par \stop
+
+In traditional \TEX\ horizontal extensibles are not really present. Accents
+are chosen from a linked list of variants and don't have an extensible
+specification. This is because most such accents grow in two dimensions and
+the only extensible like accents are rules and braces. However, in \UNICODE\
+we have a few more and also because of symmetry we decided to add horizontal
+extensibles too. Take:
+
+\startbuffer
+$ \overbrace {a+1} \underbrace {b+2} \doublebrace {c+3} $ \par
+$ \overparent{a+1} \underparent{b+2} \doubleparent{c+3} $ \par
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\getbuffer
+
+Contrary to Cambria, Latin Modern Math, which is just like
+Computer Modern Math, has no ready overbrace glyphs. Keep in mind
+that in that we're dealing with fonts that have only 256 slots and
+that the traditional font mechanism has the same limitation. For
+this reason, the (extensible) braces are traditionally made from
+snippets as is demonstrated below.

+\stoplinecorrection
+
+The four snippets have the height and depth of the rule that will
+connect them. Since we want a single interface for all fonts we no
+longer will use macro based solutions. First of all fonts like
+Cambria don't have the snippets, and using active character
+trickery (so that we can adapt the meaning to the font) has no
+preference either. This leaves virtual glyphs.
+
+It took us a bit of experimenting to get the right virtual definition because
+it is a multi||step process:
+
+\startitemize[packed]
+\item The right \UNICODE\ character (\type {0x23DE}) points to a character that has
+      no glyph itself but only horizontal extensibles.
+\item The snippets that make up the extensible don't have the right dimensions
+      (as they define the size of the connecting rule), so we need to make them
+      virtual themselves and give them a size that matches \LUATEX's expectations.
+\item Each virtual snippet contains a reference to the physical snippet and moves
+      it up or down as well as fixes its size.
+\item The second and fifth snippet are actually not real glyphs but rules. The
+      dimensions are derived from the snippets and it is shifted up or down too.
+\stopitemize
+
+You might wonder if this is worth the trouble. Well, it is if you take into
+account that all upcoming math fonts will be organized like Cambria.
+
+\subject{math kerning}
+
+While reading Microsofts orange booklet, it became clear that
+\OPENTYPE\ provides advanced kerning possibilities and we decided
+to put it on the agenda for \LUATEX.
+
+It is possible to define a ladder||like boundary for each corner
+of a character where the ladder more or less follows the shape of
+a character. In theory this means that when we attach a
+superscript to a base character we can use two such ladders to
+determine the optimal spacing between them.
+
+Let's have a look at a few characters, the upright~f and its
+italic cousin.
+
+\startcombination[2*1]
+  {\ShowGlyphShape{name:cambria-math}{40bp}{0x66}}    {U+00066}
+  {\ShowGlyphShape{name:cambria-math}{40bp}{0x1D453}} {0x1D453}
+\stopcombination
+
+The ladders on the right can be used to position a super or
+subscript, that is, they are positioned in the normal way but the
+ladder, as well as the boundingbox and/or left ladders of the
+scripts can be used to fine tune the positioning.
+
+Should we use this information? I made this visualizer for
+checking some Arabic fonts anchoring and cursive features and then
+it made sense to add some of the information related to math as
+well. \footnote {Taco extended the visualizer for his presentation
+at Bachotek 2009 so you might run into variants.} The orange
+booklet shows quite advanced ladders, and when looking at the 3500
+shapes in Cambria, it quickly becomes clear that in practice there
+is not that much detail in the specification. Nevertheless,
+because without this feature the result is not acceptable \LUATEX\
+gracefully supports it.

+\chapter{Collecting garbage}
+
+We use the \type {mk.tex} document for testing and because it keeps track of
+how \LUATEX\ evolves. As a result it has some uncommon characteristics. For
+instance, you can see increments in memory usage at points where we
+load fonts: the chapters on Zapfino, Arabic and CJK (unfinished). This memory
+is not freed because the font memory is used permanently. In the following
+graphic, the red line is the memory consumption of \LUATEX\ for the current
+version of \type {mk.tex}. The blue line is the runtime per page.
+
+\ShowNamedUsage{mk-luatex-progress}{luastate_bytes}{elapsed_time}
+
+At the moment of writing this Taco has optimized the \LUATEX\ code base and
+I have added dynamic feature support to the \MKIV\ and optimized much of the
+critical \LUA\ code. At the time of writing this (December 23, 2007),
+\type {mk.tex} counted 142 pages. Our rather aggressive optimizations brought
+down runtime from about 29 seconds to under 16 seconds. By sharing as much font
+data as possible at the \LUA\ end (at the cost of a more complex implementation)
+the memory consumption of huge fonts was brought down to a level where
+a somewhat \quote {older} computer with 512 MB memory could also cope with
+\MKIV. Keep in mind that some fonts are just real big. Eventually we may decide
+to use a more compact table model for passing \OPENTYPE\ fonts to \LUA, but this
+will not happen in 2007.
+
+The following tests show when \LUA's garbage collector becomes active. The blue
+spike shows that some extra time is spent on this initially. After that garbage
+more garbage is collected, which makes the time spent per page slightly higher.
+

+} \stoptext
+\stoptyping
+
+\ShowNamedUsage{mk-timing-1-luatex-progress}{luastate_bytes}{elapsed_time}
+
+The maximum memory footprint is somewhat misleading because \LUA\ reserves more
+than needed. As discussed in an earlier chapter, it is possible to tweak to control
+memory management somewhat, but eventually we decided that it does not make much sense
+to divert from the default settings.

+\ShowNamedUsage{mk-timing-2-luatex-progress}{luastate_bytes}{elapsed_time}
+
+The last example of this set does not load files, but stores the text in
+a macro. This is faster, although not that mich because the operating system
+caches the file and there is not \UTF\ collapsing needed for this file.
+

+\ShowNamedUsage{mk-timing-3-luatex-progress}{luastate_bytes}{elapsed_time}
+
+There are subtle differences in memory usage between the examples and eventually
+test like these will permit us to optimize the code even further. For the record:
+the first test runs in 39.5 seconds, the second on in 36.5 seconds and the last one
+only takes 31.5 seconds (all in batch mode).
+
+Keep in mind that these quotes in \type {tufte.tex} are just test samples, and
+not that realistic in everyday documents. On the other hand, these tests involve
+the usual font loading, node processing, attribute handling etc. They provide a
+decent baseline.
+
+Another document that we use for testing functionality and performance is the
+reference manual. The preliminary beta~2 version gives the following statistics.
+
+\ShowNamedUsage{luatexref-t-luatex-progress-runtime}{luastate_bytes}{elapsed_time}
+
+The previous graphic shows the statistics of a run with runtime \METAPOST\ graphics
+enabled. This means that, because each pagenumber comes with a graphic, for each
+page \METAPOST\ is called. The speed of this call is heavily influenced by the
+\METAPOST\ startup time, which in turn (in a windows platform) is influences by the
+initialization time of the \KPSE\ library. Technically the call time can near zero
+but this demands sharing libraries and databases. Anyhow, we're moving towards an
+embedded \METAPOST\ library anyway, and the next graphic shows what will happen then.
+Here we run \CONTEXT\ in delayed \METAPOST\ mode: graphics are collected and processed
+between runs. Where the runtime variant takes some 45 seconds processing time, the
+intermediate versions takes 15.
+
+\ShowNamedUsage{luatexref-t-luatex-progress-intermediate}{luastate_bytes}{elapsed_time}
+
+In the \type {mk.tex} document we use \TYPEONE\ fonts for the main body of the text and
+load some (huge) \OPENTYPE\ fonts later on. Here we use \OPENTYPE\ fonts exclusively and
+since \CONTEXT\ loads fonts only when needed, you see several spikes in the time per page
+bars and memory consumption quickly becomes stable. Interesting is that contrary to the
+\type {tufte.tex} samples, memory usage is quite stable. Here we don't have a memory
+sawtooth and no garbage collection spikes.
+
+The previous graphics combine \LUA\ memory consumption with time spent per page. The
+following graphics show variants of this. The graphics concern this document
+(\type{mk.tex}). Again, the blue lines represent the runtime per page.
+
+\ShowMemoryUsage{mk-luatex-progress}
+
+In \LUATEX\ node memory management is rewritten. Contrary to what you may expect, node memory
+consumption is not that large. Pages seldom contain more than 5000 nodes, although
+extensive use of attributes can easily duplicate this. Node usage in this documents is
+as follows.
+
+\ShowNodeUsage{mk-luatex-progress}
+
+If node memory usage stays high, i.e.\ is not reclaimed, this can be an indication of
+a memory leak. In the December 2007 beta version there is such a leak in math subformulas,
+something that will be resolved when math node processing is opened up. The current \MKIV\
+code cleans up most of its temporary data. We do so, because it permits us to keep an eye
+on unwanted memory leaks. When writing this chapter, some of the peaks in the graphics
+coincided with peaks in the runtime per page, which is no surprise.
+
+If you want to run such tests yourself, you need to load a module at startup:
+
+\starttyping
+\usemodule[timing]
+\stoptyping
+
+The graphics can be generated with:
+
+\starttyping
+\def\ShowUsage      {optional filename}
+\def\ShowNamedUsage {optional filename}{red graphic}{blue graphic}
+\def\ShowMemoryUsage{optional filename}
+\def\ShowNodeUsage  {optional filename}
+\stoptyping
+

+\chapter{The \luaTeX\ Mix}
+
+\subject{introduction}
+
+The idea of embedding \LUA\ into \TEX\ originates in some
+experiments with \LUA\ embedded in the \SCITE\ editor. You can add
+functionality to this editor by loading \LUA\ scripts. This is
+accomplished by a library that gives access to the internals of
+the editing component.
+
+The first integration of \LUA\ in \PDFTEX\ was relatively simple:
+from \TEX\ one could call out to \LUA\ and from \LUA\ one could
+print to \TEX. My first application was converting math encoded a
+calculator syntax to \TEX. Following experiments dealt with
+\METAPOST. At this point integration meant as little as: having some
+scripting language as addition to the macro language. But, even in
+this early stage further possibilities were explored, for instance
+in manipulating the final output (i.e.\ the \PDF\ code). The first
+versions of what by then was already called \LUATEX\ provided
+access to some internals, like counter and dimension registers and
+the dimensions of boxes.
+
+Boosted by the oriental \TeX\ project, the team started exploring
+more fundamental possibilities: hooks in the input|/|output,
+tokenization, fonts and nodelists. This was followed by opening up
+hyphenation, breaking lines into paragraphs and building
+ligatures. At that point we not only had access to some internals
+but also could influence the way \TEX\ operates.
+
+After that, an excursion was made to \MPLIB, which fulfilled a
+long standing wish for a more natural integration of \METAPOST\
+into \TEX. At that point we ended up with mixtures of \TEX, \LUA\
+and \METAPOST\ code.
+
+Medio 2008 we still need to open up more of \TEX, like page
+building, math, alignments and the backend. Eventually \LUATEX\
+will be nicely split up in components, rewritten in \CCODE, and we may
+even end up with \LUA\ glueing together the components that make
+up the \TEX\ engine. At that point the interoperation between
+\TEX\ and \LUA\ may be more rich that it is now.
+
+In the next sections I will discuss some of the ideas behind
+\LUATEX\ and the relationship between \LUA\ and \TEX\ and how it
+presents itself to users. I will not discuss the interface itself,
+which consists of quite some functions (organized in pseudo
+libraries) and the mechanisms used to access and replace internals
+(we call them callbacks).
+
+\subject {tex vs. lua}
+
+\TEX\ is a macro language. Everything boils down to either allowing
+stepwise expansion or explicitly preventing it. There are no real
+control features, like loops; tail recursion is a key concept.
+There are few accessible data|-|structures like numbers, dimensions,
+glue, token lists and boxes. What happens inside \TEX\ is
+controlled by variables, mostly hidden from view, and optimized
+within the constraints of 30 years ago.
+
+The original idea behind \TEX\ was that an author would write a
+specific collection of macros for each publication, but increasing
+popularity among non-programmers quickly resulted in distributed
+collections of macros, called macro packages. They started small
+but grew and grew and by now have become pretty large. In these
+packages there are macros dealing with fonts, structure, page
+layout, graphic inclusion, etc. There is also code dealing with
+user interfaces, process control, conversion and much of that code
+looks out of place: the lack of control features and string
+manipulation is solved by mimicking other languages, the
+unavailability of a float datatype is compensated by misusing
+dimension registers, and you can find provisions to force or
+inhibit expansion all over the place.
+
+\TEX\ is a powerful typographical programming language but
+lacks some of the handy features of scripting languages. Handy in the
+sense that you will need them when you want to go beyond the
+original purpose of the system. \LUA\ is a powerful scripting
+language, but knows nothing of typesetting. To some extent it
+resembles the language that \TEX\ was written in: \PASCAL. And,
+since \LUA\ is meant for embedding and extending existing systems,
+it makes sense to bring \LUA\ into \TEX. How do they compare?
+Let's give some examples.
+
+About the simplest example of using \LUA\ in \TEX\ is the following:
+
+\starttyping
+\directlua { tex.print(math.sqrt(10)) }
+\stoptyping
+
+This kind of application is probably what most users will want and
+use, if they use \LUA\ at all. However, we can go further than that.
+
+In \TEX\ a loop can be implemented as in the plain format
+(copied with comment):
+
+\starttyping
+\def\loop#1\repeat{\def\body{#1}\iterate}
+\def\iterate{\body\let\next\iterate\else\let\next\relax\fi\next}
+\let\repeat=\fi % this makes \loop...\if...\repeat skippable
+\stoptyping
+
+This is then used as:
+
+\starttyping
+\newcount \mycounter \mycounter=1
+\loop
+    ...
+    \advance\mycounter 1
+    \ifnum\mycounter < 11
+\repeat
+\stoptyping
+
+The definition shows a bit how \TEX\ programming works. Of course
+such definitions can be wrapped in macros, like:
+
+\starttyping
+\forloop{1}{10}{1}{some action}
+\stoptyping
+
+and this is what often happens in more complex macro packages. In
+order to use such control loops without side effects, the macro
+writer needs to take measures that permit for instance nested
+usage and avoids clashes between local variables (counters or
+macros) and user defined ones. Here we use a counter in the
+condition, but in practice expressions will be more complex
+and this is not that trivial to implement.
+
+The original definition of the iterator can be written a bit
+more efficient:
+
+\starttyping
+\def\iterate{\body \expandafter\iterate \fi}
+\stoptyping
+
+And indeed, in macro packages you will find many such expansion
+control primitives being used, which does not make reading macros
+easier.
+
+Now, get me right, this does not make \TEX\ less powerful, it's
+just that the language is focused on typesetting and not on
+general purpose programming, and in principle users can do
+without: documents can be preprocessed using another language, and
+document specific styles can be used.
+
+We have to keep in mind that \TEX\ was written in a time when
+resources in terms of memory and \CPU\ cycles weres less abundant
+than they are now. The 255 registers per class and the about 3000
+hash slots in original \TEX\ were more than enough for typesetting
+a book, but in huge collections of macros they are not all that much. For
+that reason many macropackages use obscure names to hide their
+private registers from users and instead of allocating new ones
+with meaningful names, existing ones are shared. It is therefore
+not completely fair to compare \TEX\ code with \LUA\ code: in \LUA\
+we have plenty of memory and the only limitations are those
+imposed by modern computers.
+
+In \LUA, a loop looks like this:
+
+\starttyping
+for i=1,10 do
+    ...
+end
+\stoptyping
+
+But while in the \TEX\ example, the content directly ends up in
+the input stream, in \LUA\ we need to do that explicitly, so in
+fact we will have:
+
+\starttyping
+for i=1,10 do
+    tex.print("...")
+end
+\stoptyping
+
+And, in order to execute this code snippet, in \LUATEX\ we will do:
+
+\starttyping
+\directlua 0 {
+    for i=1,10 do
+        tex.print("...")
+    end
+}
+\stoptyping
+
+So, eventually we will end up with more code than just \LUA\ code,
+but still the loop itself looks quite readable and more complex loops
+are possible:
+
+\starttyping
+\directlua 0 {
+    local t, n = { }, 0
+    while true do
+        local r = math.random(1,10)
+        if not t[r] then
+            t[r], n = true, n+1
+            tex.print(r)
+            if n == 10 then break end
+        end
+    end
+}
+\stoptyping
+
+This will typeset the numbers 1 to 10 in randomized order.
+Implementing a random number generator in pure \TEX\ takes some bit of
+code and keeping track of already defined numbers in macros can be
+done with macros, but both are not very efficient.
+
+I already stressed that \TEX\ is a typographical programming
+language and as such some things in \TEX\ are easier than in \LUA,
+given some access to internals:
+
+\starttyping
+\setbox0=\hbox{x} \the\wd0
+\stoptyping
+
+In \LUA\ we can do this as follows:
+
+\starttyping
+\directlua 0 {
+    local n = node.new('glyph')
+    n.font = font.current()
+    n.char = string.byte('x')
+    tex.box[0] = node.hpack(n)
+    tex.print(tex.box[0].width/65536 .. "pt")
+}
+\stoptyping
+
+One pitfall here is that \TEX\ rounds the number differently than
+\LUA. Both implementations can be wrapped in a macro cq. function:
+
+\starttyping
+\def\measured#1{\setbox0=\hbox{#1}\the\wd0\relax}
+\stoptyping
+
+Now we get:
+
+\starttyping
+\measured{x}
+\stoptyping
+
+The same macro using \LUA\ looks as follows:
+
+\starttyping
+\directlua 0 {
+    function measure(chr)
+        local n = node.new('glyph')
+        n.font = font.current()
+        n.char = string.byte(chr)
+        tex.box[0] = node.hpack(n)
+        tex.print(tex.box[0].width/65536 .. "pt")
+    end
+}
+\def\measured#1{\directlua0{measure("#1")}}
+\stoptyping
+
+In both cases, special tricks are needed if you want to pass for
+instance a \type {#} to \TEX's variant, or a \type {"} to \LUA. In
+both cases we can use shortcuts like \type {\#} and in the second
+case we can pass strings as long strings using double square
+brackets to \LUA.
+
+This example is somewhat misleading. Imagine that we want to
+pass more than one character. The \TEX\ variant is already suited
+for that, but the function will now look like:
+
+\starttyping
+\directlua 0 {
+    function measure(str)
+        if str == "" then
+            tex.print("0pt")
+        else
+            local head, tail = nil, nil
+            for chr in str:gmatch(".") do
+                local n = node.new('glyph')
+                n.font = font.current()
+                n.char = string.byte(chr)
+                if not head then
+                    head = n
+                else
+                    tail.next = n
+                end
+                tail = n
+            end
+            tex.box[0] = node.hpack(head)
+            tex.print(tex.box[0].width/65536 .. "pt")
+        end
+    end
+}
+\stoptyping
+
+And still it's not okay, since \TEX\ inserts kerns between
+characters (depending on the font) and glue between words, and
+doing that all in \LUA\ takes more code. So, it will be clear that
+although we will use \LUA\ to implement advanced features, \TEX\
+itself still has quite some work to do.
+
+In the following example we show code, but this is not of
+production quality. It just demonstrates a new way of dealing
+with text in \TEX.
+
+Occasionally a design demands that at some place the first
+character of each word should be uppercase, or that the first word
+of a paragraph should be in small caps, or that each first line of a
+paragraph has to be in dark blue. When using traditional \TEX\ the user
+then has to fall back on parsing the data stream, and preferably
+you should then start such a sentence with a command that can pick
+up the text. For accentless languages like English this is quite
+doable but as soon as commands (for instance dealing with accents)
+enter the stream this process becomes quite hairy.
+
+The next code shows how \CONTEXT\ \MKII\ defines the \type {\Word}
+and \type {\Words} macros that capitalize the first characters of
+word(s). The spaces are really important here because they signal
+the end of a word.
+
+\starttyping
+\def\doWord#1%
+  {\bgroup\the\everyuppercase\uppercase{#1}\egroup}
+
+\def\Word#1%
+  {\doWord#1}
+
+\def\doprocesswords#1 #2\od
+  {\doifsomething{#1}{\processword{#1} \doprocesswords#2 \od}}
+
+\def\processwords#1%
+  {\doprocesswords#1 \od\unskip}
+
+\let\processword\relax
+
+\def\Words
+  {\let\processword\Word \processwords}
+\stoptyping
+
+Actually, the code is not that complex. We split of words and feed
+them to a macro that picks up the first token (hopefully a character)
+which is then fed into the \type {\uppercase} primitive. This assumes that
+for each character a corresponding uppercase variant is defined using the
+\type {\uccode} primitive. Exceptions can be dealt with by assigning relevant
+code to the token register \type {\everyuppercase}.
+However, such macros are far from robust. What happens if the text
+is generated and not input as-is? What happens with commands in
+the stream that do something with the following tokens?
+
+A \LUA\ based solution can look as follows:
+
+\starttyping
+\def\Words#1{\directlua 0
+    for s in unicode.utf8.gmatch("#1", "([^ ])") do
+        tex.sprint(string.upper(s:sub(1,1)) .. s:sub(2))
+    end
+}
+\stoptyping
+
+But there is no real advantage here, apart from the fact that less code
+is needed. We still operate on the input and therefore we need to look
+to a different kind of solution: operating on the node list.
+
+\starttyping
+function CapitalizeWords(head)
+    local done = false
+    local glyph = node.id("glyph")
+    for start in node.traverse_id(glyph,head) do
+        local prev, next = start.prev, start.next
+        if prev and prev.id == kern and prev.subtype == 0 then
+            prev = prev.prev
+        end
+        if next and next.id == kern and next.subtype == 0 then
+            next = next.next
+        end
+        if (not prev or prev.id ~= glyph) and
+                    next and next.id == glyph then
+            done = upper(start)
+        end
+    end
+    return head, done
+end
+\stoptyping
+
+A node list is a forward|-|linked list. With a helper
+function in the \type {node} library we can loop over such lists. Instead
+of traversing we can use a regular while loop, but it is probably less
+efficient in this case. But how to apply this function to the relevant
+part of the input? In \LUATEX\ there are several callbacks that operate
+on the horizontal lists and we can use one of them to plug in this
+function. However, in that case the function is applied to probably
+more text than we want.
+
+The solution for this is to assign attributes to the range of text
+that such a function has to take care of. These attributes (there
+can be many) travel with the nodes. This is also a reason why such
+code normally is not written by end users, but by macropackage
+writers: they need to provide the frameworks where you can plug in
+code. In \CONTEXT\ we have several such mechanisms and therefore
+in \MKIV\ this function looks (slightly stripped) as follows:
+
+\starttyping
+function cases.process(namespace,attribute,head)
+    local done, actions = false, cases.actions
+    for start in node.traverse_id(glyph,head) do
+        local attr = has_attribute(start,attribute)
+        if attr and attr > 0 then
+            unset_attribute(start,attribute)
+            local action = actions[attr]
+            if action then
+                local _, ok = action(start)
+                done = done and ok
+            end
+        end
+    end
+    return head, done
+end
+\stoptyping
+
+Here we check attributes (these are set at the \TEX\ end) and we have
+all kind of actions that can be applied, depending on the value of the
+attribute. Here the function that does the actual uppercasing
+is defined somewhere else. The \type {cases} table provides us a
+namespace; such namespaces needs to be coordinated by macro package
+writers.
+
+This approach means that the macro code looks completely different; in
+pseudo code we get:
+
+\starttyping
+\def\Words#1{{<setattribute><cases><somevalue>#1}}
+\stoptyping
+
+Or alternatively:
+
+\starttyping
+\def\StartWords{\begingroup<setattribute><cases><somevalue>}
+\def\StopWords {\endgroup}
+\stoptyping
+
+Because starting a paragraph with a group can have unwanted side
+effects (like \type {\everypar} being expanded inside a group) a
+variant is:
+
+\starttyping
+\def\StartWords{<setattribute><cases><somevalue>}
+\def\StopWords {<resetattribute><cases>}
+\stoptyping
+
+So, what happens here is that the users sets an attribute using some high
+level command, and at some point during the transformation of the input into
+node lists, some action takes place. At that point commands, expansion and
+whatever no longer can interfere.
+
+In addition to some infrastructure, macro packages need to carry some
+knowledge, just as with the \type {\uccode} used in \type {\uppercase}.
+The \type {upper} function in the first example looks as follows:
+
+\starttyping
+local function upper(start)
+    local data, char = characters.data, start.char
+    if data[char] then
+        local uc = data[char].uccode
+        if uc and fonts.ids[start.font].characters[uc] then
+            start.char = uc
+            return true
+        end
+    end
+    return false
+end
+\stoptyping
+
+Such code is really macro package dependent: \LUATEX\ only
+provides the means, not the solutions. In \CONTEXT\ we have
+collected information about characters in a \type {data} table
+in the \type {characters} namespace. There we have stored the
+uppercase codes (\type {uccode}). The, again \CONTEXT\ specific,
+\type {fonts} table keeps track of all defined fonts and before
+we change the case, we make sure that this character is present
+in the font. Here \type {id} is the number by which
+\LUATEX\ keeps track of the used fonts. Each glyph node carries
+such a reference.
+
+In this example, eventually we end up with more code than in \TEX,
+but the solution is much more robust. Just imagine what would happen
+when in the \TEX\ solution we would have:
+
+\starttyping
+\Words{\framed[offset=3pt]{hello world}}
+\stoptyping
+
+It simply does not work. On the other hand, the \LUA\ code never
+sees \TEX\ commands, it only sees the two words represented by
+glyphs nodes and separated by glue.
+
+Of course, there is a danger when we start opening \TEX's core
+features. Currently macro packages know what to expect, they know
+what \TEX\ can and cannot do. Of course macro writers have
+exploited every corner of \TEX, even the dark ones. Where dirty
+tricks in the \TEX book had an educational purpose, those of users
+sometimes have obscene traits. If we just stick to the trickery
+introduced for parsing input, converting this into that, doing
+some calculations, and alike, it will be clear that \LUA\ is more
+than welcome. It may hurt to throw away thousands of lines of
+impressive code and replace it by a few lines of \LUA\ but that's
+the price the user pays for abusing \TEX. Eventually \CONTEXT\ \MKIV\
+will be a decent mix of \LUA\ and \TEX\ code, and hopefully the
+solutions programmed in those languages are as clean as possible.
+
+Of course we can discuss until eternity whether \LUA\ is the best
+choice. Taco, Hartmut and I are pretty confident that it is, and
+in the couple of years that we are working on \LUATEX\ nothing has proved
+us wrong yet. We can fantasize about concepts, only to find out that
+they are impossible to implement or hard to agree on; we just go
+ahead using trial and error. We can talk over and over how opening up
+should be done, which is what the team does in a nicely
+closed and efficient loop, but at some points decisions have to be
+made. Nothing is perfect, neither is \LUATEX, but most users won't
+notice it as long as it extends \TEX's live and makes usage more
+convenient.
+
+Users of \TEX\ and \METAPOST\ will have noticed that both
+languages have their own grouping (scope) model. In \TEX\ grouping
+is focused on content: by grouping the macro writer (or author)
+can limit the scope to a specific part of the text or keep certain
+macros live within their own world.
+
+\starttyping
+.1. \bgroup .2. \egroup .1.
+\stoptyping
+
+Everything done at 2 is local unless explicitly told otherwise.
+This means that users can write (and share) macros with a small
+chance of clashes. In \METAPOST\ grouping is available too, but
+variables explicitly need to be saved.
+
+\starttyping
+.1. begingroup ; save p ; path p ; .2. endgroup .1.
+\stoptyping
+
+After using \METAPOST\ for a while this feels quite natural
+because an enforced local scope demands multiple return values
+which is not part of the macro language. Actually, this is another
+fundamental difference between the languages: \METAPOST\ has (a
+kind of) functions, which \TEX\ lacks. In \METAPOST\ you can write
+
+\starttyping
+draw origin for i=1 upto 10 : .. (i,sin(i)) endfor ;
+\stoptyping
+
+but also:
+
+\starttyping
+draw some(0) for i=1 upto 10 : .. some(i) endfor ;
+\stoptyping
+
+with
+
+\starttyping
+vardef some (expr i) =
+    if i > 4 : i = i - 4 fi ;
+    (i,sin(i))
+enddef ;
+\stoptyping
+
+The condition and assignment in no way interfere with the loop where
+this function is called, as long as some value is returned (a pair in
+this case).
+
+In \TEX\ things work differently. Take this:
+
+\starttyping
+\count0=1
+\message{\advance\count0 by 1 \the\count0}
+\the\count0
+\stoptyping
+
+The terminal wil show:
+
+\starttyping
+\advance \count 0 by 1 1
+\stoptyping
+
+At the end the counter still has the value~1. There are quite some
+situations like this, for instance when data like a table of
+contents has to be written to a file. You cannot write macros where
+such calculations are done and hidden and only the result is seen.
+
+The nice thing about the way \LUA\ is presented to the user is that it
+permits the following:
+
+\starttyping
+\count0=1
+\message{\directlua0{tex.count[0] = tex.count[0] + 1}\the\count0}
+\the\count0
+\stoptyping
+
+This will report~2 to the terminal and typeset a 2 in the
+document. Of course this does not solve everything, but it is a
+step forward. Also, compared to \TEX\ and \METAPOST, grouping is
+done differently: there is a \type {local} prefix that makes
+variables (and functions are variables too) local in modules,
+functions, conditions, loops etc. The \LUA\ code in this story
+contains such locals.
+
+In practice most users will use a macro package and so, if a user
+sees \TEX, he or she sees a user interface, not the code behind
+it. As such, they will also not encounter the code written in
+\LUA\ that deals with for instance fonts or node list
+manipulations. If a user sees \LUA, it will most probably be in
+processing actual data. Therefore, in the next section I will give an
+example of two ways to deal with \XML: one more suitable for
+traditional \TEX, and one inspired by \LUA. It demonstrates how
+the availability of \LUA\ can result in different solutions for
+the same problem.
+
+\subject {an example: xml}
+
+In \CONTEXT\ \MKII, the version that deals with \PDFTEX\ and \XETEX,
+we use a stream based \XML\ parser, written in \TEX. Each \type {<}
+and \type {&} triggers a macro that then parses the tag and/or entity.
+This method is quite efficient in terms of memory but the associated
+code is not simple because it has to deal with attributes, namespaces
+and nesting.
+
+The user interface is not that complex, but involves quite some
+commands. Take for instance the following \XML\ snippet:
+
+\starttyping
+<document>
+    <section>
+        <title>Whatever</title>
+        <p>some text</p>
+        <p>some more</p>
+    </section>
+</document>
+\stoptyping
+
+When using \CONTEXT\ commands, we can imagine the following definitions:
+
+\starttyping
+\defineXMLenvironment[document]{\starttext} {\stoptext}
+\defineXMLargument   [title]   {\section}
+\defineXMLenvironment[p]       {\ignorespaces}{\par}
+\stoptyping
+
+When attributes have to be dealt with, for instance a reference to
+this section, things quickly start looking more complex. Also,
+users need to know what definitions to use in situations like this:
+
+\starttyping
+<table>
+    <tr><td>first</td><td>...</td> <td>last</td></tr>
+    <tr><td>left</td><td>...</td> <td>right</td></tr>
+</table>
+\stoptyping
+
+Here we cannot be sure if a cell does not contain a nested table,
+which is why we need to define the mapping as follows:
+
+\starttyping
+\defineXMLnested[table]{\bTABLE} {\eTABLE}
+\defineXMLnested[tr]   {\bTR}    {\eTR}
+\defineXMLnested[td]   {\bTD}    {\eTD}
+\stoptyping
+
+The \type {\defineXMLnested} macro is rather messy because it has
+to collect snippets and keep track of the nesting level, but users
+don't see that code, they just need to know when to use what
+macro. Once it works, it keeps working.
+
+Unfortunately mappings from source to style are never that simple
+in real life. We usually need to collect, filter and relocate
+data. Of course this can be done before feeding the source to
+\TEX, but \MKII\ provides a few mechanisms for that too. If for
+instance you want to reverse the order you can do this:
+
+\starttyping
+<article>
+    <title>Whatever</title>
+    <author>Someone</author>
+    <p>some text</p>
+</article>
+\stoptyping
+
+\starttyping
+\defineXMLenvironment[article]
+    {\defineXMLsave[author]}
+    {\blank author: \XMLflush{author}}
+\stoptyping
+
+This will save the content of the \type {author} element and flush
+it when the end tag \type {article} is seen. So, given previous
+definitions, we will get the title, some text and then the author.
+You may argue that instead we should use for instance \XSLT\ but
+even then a mapping is needed from the \XML\ to \TEX, and it's a
+matter of taste where the burden is put.
+
+Because \CONTEXT\ also wants to support standards like
+\MATHML, there are some more mechanisms but these are hidden from
+the user. And although these do a good job in most cases, the code
+associated with the solutions has never been satisfying.
+
+Supporting \XML\ this way is doable, and \CONTEXT\ has used this method
+for many years in fairly complex situations. However, now that we
+have \LUA\ available, it is possible to see if some things can be done
+simpler (or differently).
+
+After some experimenting I decided to write a full blown \XML\
+parser in \LUA, but contrary to the stream based approach, this
+time the whole tree is loaded in memory. Although this uses more
+memory than a streaming solution, in practice the difference is
+not significant because often in \MKII\ we also needed to store
+whole chunks.
+
+Loading \XML\ files in memory is real fast and once it is done we
+can have access to the elements in a way similar to \XPATH. We can
+selectively pipe data to \TEX\ and manipulate content using \TEX\
+or \LUA. In most cases this is faster than the stream|-|based
+method. Interesting is that we can do this without linking to
+existing \XML\ libraries, and as a result we are pretty
+independent.
+
+So how does this look from the perspective of the user? Say that
+we have the simple article definition stored in \type {demo.xml}.
+
+\starttyping
+<?xml version ='1.0'?>
+<article>
+    <title>Whatever</title>
+    <author>Someone</author>
+    <p>some text</p>
+</article>
+\stoptyping
+
+This time we associate so called setups with the elements. Each
+element can have its own setup, and we can use expressions to
+assign them. Here we have just one such setup:
+
+\starttyping
+\startxmlsetups xml:document
+   \xmlsetsetup{main}{article}{xml:article}
+\stopxmlsetups
+\stoptyping
+
+When loading the document it will automatically be associated with the tag \type
+{main}. The previous rule associates setup \type {xml:article}
+with the \type {article} element in tree \type {main}. We need to
+register this setup so that it will be applied to the document
+after loading:
+
+\starttyping
+\xmlregistersetup{xml:document}
+\stoptyping
+
+and the document itself is processed with:
+
+\starttyping
+\xmlprocessfile{main}{demo.xml}{} % optional setup
+\stoptyping
+
+The setup \type {xml:article} can look as follows:
+
+\starttyping
+\startxmlsetups xml:article
+    \section{\xmltext{#1}{/title}}
+    \xmlall{#1}{!(title|author)}
+    \blank author: \xmltext{#1}{/author}
+\stopxmlsetups
+\stoptyping
+
+Here \type {#1} refers to the current node in the \XML\ tree, in
+this case the root element, \type {article}. The second argument
+of \type {\xmltext} and \type {\xmlall} is a path expression,
+comparable with \XPATH: \type {/title} means: the \type {title}
+element anchored to the current root (\type{#1}), and \type
+{!(title|author)} is the negation of (complement to) \type{title}
+or \type {author}. Such expressions can be more complex that the
+one above, like:
+
+\starttyping
+\xmlfirst{#1}{/one/(alpha|beta)/two/text()}
+\stoptyping
+
+which returns the content of the first element that satisfies one of
+the paths (nested tree):
+
+\starttyping
+/one/alpha/two
+/one/beta/two
+\stoptyping
+
+There is a whole bunch of commands like \type {\xmltext} that
+filter content and pipe it into \TEX. These are calling \LUA\
+functions. This is no manual, so we will not discuss them here.
+However, it is important to realize that we have to associate
+setups (consider them free formatted macros) to at least one
+element in order to get started. Also, \XML\ inclusions have to be
+dealt with before assigning the setups. These are simple
+one|-|line commands. You can also assign defaults to elements,
+which saves some work.
+
+Because we can use \LUA\ to access the tree and manipulate
+content, we can now implement parts of \XML\ handling in \LUA. An
+example of this is dealing with so|-|called Cals tables. This is
+done in approximately 150 lines of \LUA\ code, loaded at runtime in a
+module. This time the association uses functions instead of setups and those
+functions will pipe data back to \TEX. In the module you will find:
+
+\starttyping
+\startxmlsetups xml:cals:process
+    \xmlsetfunction {\xmldocument} {cals:table} {lxml.cals.table}
+\stopxmlsetups
+
+\xmlregistersetup{xml:cals:process}
+
+\xmlregisterns{cals}{cals}
+\stoptyping
+
+These commands tell \MKIV\ that elements with a namespace
+specification that contains \type {cals} will be remapped to the
+internal namespace \type {cals} and the setup associates a
+function with this internal namespace.
+
+By now it will be clear that from the perspective of the user
+hardly any \LUA\ is visible. Sure, he or she can deduce that deep
+down some magic takes place, especially when you run into more
+complex expressions like this (the \type {@} denotes an
+attribute):
+
+\starttyping
+\xmlsetsetup
+    {main} {item[@type='mpctext' or @type='mrtext']}
+    {questions:multiple:text}
+\stoptyping
+
+Such expressions resemble \XPATH, but can go much further than
+that, just by adding more functions to the library.
+
+\starttyping
+b[position() > 2 and position() < 5 and text() == 'ok']
+b[position() > 2 and position() < 5 and text() == upper('ok')]
+b[@n=='03' or @n=='08']
+b[number(@n)>2 and number(@n)<6]
+b[find(text(),'ALSO')]
+\stoptyping
+
+Just to give you an idea \unknown\ in the module that implements
+the parser you will find definitions that match the function calls
+in the above expressions.
+
+\starttyping
+xml.functions.find   = string.find
+xml.functions.upper  = string.upper
+xml.functions.number = tonumber
+\stoptyping
+
+So much for the different approaches. It's up to the user what
+method to use: stream based \MKII, tree based \MKIV, or a mixture.
+
+The main reason for taking \XML\ as an example of mixing \TEX\ and
+\LUA\ is in that it can be a bit mind boggling if you start
+thinking of what happens behind the screens. Say that we have
+
+\starttyping
+<?xml version ='1.0'?>
+<article>
+    <title>Whatever</title>
+    <author>Someone</author>
+    <p>some <b>bold</b> text</p>
+</article>
+\stoptyping
+
+and that we use the setup shown before with \type {article}.
+
+At some point, we are done with defining setups and load the
+document. The first thing that happens is that the list of
+manipulations is applied: file inclusions are processed first,
+setups and functions are assigned next, maybe some elements are
+deleted or added, etc. When that is done we serialize the tree to
+\TEX, starting with the root element. When piping data to \TEX\ we
+use the current catcode regime; linebreaks and spaces are honored
+as usual.
+
+Each element can have a function (command) associated and when
+this is the case, control is given to that function. In our case
+the root element has such a command, one that will trigger a
+setup. And so, instead of piping content to \TEX, a function is
+called that lets \TEX\ expand the macro that deals with this
+setup.
+
+However, that setup itself calls \LUA\ code that filters the title
+and feeds it into the \type {\section} command, next it flushes
+everything except the title and author, which again involves
+calling \LUA. Last it flushes the author. The nested sequence
+of events is as follows:
+
+\startitemize[2*broad]
+
+    \sym{lua:} Load the document and apply setups and alike.
+
+    \sym{lua:} Serialize the \type {article} element, but since
+    there is an associated setup, tell \TEX\ do expand that one
+    instead.
+
+    \startitemize[2*broad]
+
+        \sym{tex:} Execute the setup, first expand the \type {\section}
+        macro, but its argument is a call to \LUA.
+
+        \startitemize[2*broad]
+
+            \sym{lua:} Filter \type {title} from the subtree under
+            \type {article}, print the content to \TEX\ and return
+            control to \TEX.
+
+        \stopitemize
+
+        \sym{tex:} Tell \LUA\ to filter the paragraphs i.e.\ skip \type
+        {title} and \type {author}; since the \type {b} element has
+        no associated setup (or whatever) it is just serialized.
+
+        \startitemize[2*broad]
+
+            \sym{lua:} Filter the requested elements and return control
+            to \TEX.
+
+        \stopitemize
+
+        \sym{tex:} Ask \LUA\ to filter \type {author}.
+
+        \startitemize[2*broad]
+            \sym{lua:} Pipe \type {author}'s content to \TEX.
+        \stopitemize
+
+        \sym{tex:} We're done.
+
+    \stopitemize
+
+    \sym{lua:} We're done.
+
+\stopitemize
+
+This is a really simple case. In my daily work I am dealing
+with rather extensive and complex educational documents where in
+one source there is text, math, graphics, all kind of fancy stuff,
+questions and answers in several categories and of different kinds,
+either or not to be reshuffled, omitted or combined. So there
+we are talking about many more levels of \TEX\ calling \LUA\ and \LUA\
+piping to \TEX\ etc. To stay in \TEX\ speak: we're dealing with
+one big ongoing nested expansion (because \LUA calls expand), and
+you can imagine that this somewhat stresses \TEX's input stack, but
+so far I have not encountered any problems.
+
+\subject{some remarks}
+
+Here I discussed several possible applications of \LUA\ in \TEX. I
+didn't mention yet that because \LUATEX\ contains a scripting engine
+plus some extra libraries, it can also be used purely for that.
+This means that support programs can now be written in \LUA\ and
+that there are no longer dependencies of other scripting engines
+being present on the system. Consider this a bonus.
+
+Usage in \TEX\ can be organized in four categories:
+
+\startitemize[n]
+\item  Users can use \LUA\ for generating data, do all kind of
+       data manipulations, maybe read data from file, etc. The
+       only link with \TEX\ is the print function.
+\item  Users can use information provided by \TEX\ and use this
+       when making decisions. An example is collecting data in
+       boxes and use \LUA\ to do calculations with the dimensions.
+       Another example is a converter from \METAPOST\ output to
+       \PDF\ literals. No real knowledge of \TEX's internals is
+       needed. The \MKIV\ \XML\ functionality discussed before
+       demonstrates this: it's mostly data processing and piping
+       to \TEX. Other examples are dealing with buffers, defining
+       character mappings, and handling error messages, verbatim
+       \unknown\ the list is long.
+\item  Users can extend \TEX's core functionality. An example is
+       support for \OPENTYPE\ fonts: \LUATEX\ itself does not
+       support this format directly, but provides ways to feed
+       \TEX\ with the relevant information. Support for \OPENTYPE\
+       features demands manipulating node lists. Knowledge of
+       internals is a requirement. Advanced spacing and language
+       specific features are made possible by node list
+       manipulations and attributes. The alternative \type {\Words}
+       macro is an example of this.
+\item  Users can replace existing \TEX\ functionality. In \MKIV\
+       there are numerous example of this, for instance all file
+       \IO\ is written in \LUA, including reading from \ZIP\ files
+       and remote locations. Loading and defining fonts is also
+       under \LUA\ control. At some point \MKIV\ will provide
+       dedicated splitters for multicolumn typesetting and
+       probably also better display spacing and display
+       math splitting.
+\stopitemize
+
+The boundaries between these categories are not frozen. For
+instance, support for image inclusion and \MPLIB\ in \CONTEXT\
+\MKIV\ sits between category 3 and~4. Category 3 and~4, and
+probably also~2 are normally the domain of macro package writers
+and more advanced users who contribute to macro packages. Because
+a macropackage has to provide some stability it is not a good idea
+to let users mess around with all those internals, because of
+potential interference. On the other hand, normally users operate
+on top of a kernel using some kind of \API\ and history has
+proved that macro packages are stable enough for this.
+
+Sometime around 2010 the team expects \LUATEX\ to be feature
+complete and stable. By that time I can probably provide a more
+detailed categorization.

+% \subject{Hans Hagen \& Taco Hoekwater} \blank[3*big]
+
+This chapter is written by Taco and Hans around the time
+that \MPLIB\ was integrated into \LUATEX.
+It is part of our torture test.
+
+\subject{introduction}
+
+If \METAPOST\ support had not been as tightly integrated into
+\CONTEXT\ as it is, at least half of the projects \PRAGMA\ has
+been doing in the last decade could not have been done at all.
+\starttextbackground[sideline]Take for instance
+backgrounds behind text or graphic markers alongside text. These are
+probably the most complex mechanisms in \CONTEXT: positions are
+stored, and positional information is passed on to
+\METAPOST, where intersections between the text areas and the running
+text are converted into graphics that are then positioned in the
+background of the text.\stoptextbackground{} Underlining of text
+(sometimes used in the educational documents that we typeset) and
+change bars (in the margins) are implemented using the same
+mechanism because those are basically a background with only one of the
+frame sides drawn.
+
+You can probably imagine that a 300 page document with several such
+graphics per page takes a while to process. A nice example of such
+integrated graphics is the \LUATEX\ reference manual, that has an
+unique graphic at each page: a stylized image of a revolving moon.

+
+Most of the running time integrating such graphics seemed to be
+caused by the mechanics of the process: starting the separate
+\METAPOST\ interpreter and having to deal with a number of
+temporary files. Therefore our expectations were high with regards
+to integrating \METAPOST\ more tightly into \LUATEX. Besides the
+speed gain, it also true that the simpler the process of using
+such use of graphics becomes, the more modern a \TEX\ runs looks
+and the less problems new users will have with understanding how
+all the processes cooperate.
+
+This article will not discuss the application interface of the
+\MPLIB\ library in detail, for that there is the \LUATEX\ manual. In short,
+using the embedded \METAPOST\ interpreter in \LUATEX\ boils
+down to the following:
+
+\startitemize[packed]
+\item Open an instance using \type {mplib.new}, either to process
+      images with a format to be loaded, or to create such a format.
+      This function returns a library object.
+\item Execute sequences of \METAPOST\ commands, using the object's
+      \type{execute} method. This returns a result.
+\item Check if the result is valid and (if it is okay) request the list
+      of objects. Do whatever you want with them, most probably
+      convert them to some output format. You can also request a
+      string representation of a graphic in \POSTSCRIPT\ format.
+\stopitemize
+
+There is no need to close the library object. As long as you didn't make
+any fatal errors, the library recovers well and can stay alive during
+the entire \LUATEX\ run.
+
+Support for \MPLIB\ depends on a few components: integration,
+conversion and extensions. This article shows some of the code
+involved in supporting the library. Let's start with the conversion.
+
+\subject{conversion}
+
+The result of a \METAPOST\ run traditionally is a \POSTSCRIPT\
+language description of the generated graphic(s). When
+\PDF\ is needed, that \POSTSCRIPT\ code has to be converted to the target
+format. This includes embedded text as well as penshapes used for
+drawing. To demonstrate, here is a simple example graphic:
+
+\startluacode
+document.sample_mp_graphic = [[
+    draw fullcircle
+        scaled 2cm
+        withpen pencircle xscaled 1mm yscaled .5mm rotated 30
+        withcolor .75red ;
+]]
+\stopluacode
+
+\startbuffer[mpexample]
+draw fullcircle
+  scaled 2cm
+  withpen pencircle xscaled 1mm yscaled .5mm rotated 30
+  withcolor .75red ;
+\stopbuffer
+
+\placefigure
+  [left]
+  {}
+  {\startMPcode \ctxlua{tex.sprint(document.sample_mp_graphic)}\stopMPcode}
+
+\typebuffer[mpexample]
+
+Notice how the pen is not a circle but a rotated ellipse. Later on it
+will become clear what the consequences of that are for the conversion.
+
+How does this output look in \POSTSCRIPT ? If the preamble is left out
+it looks like this:
+
+\startbuffer
+\startluacode
+do
+  local mpx = metapost.format("metafun")
+  local result = mpx:execute(string.format("beginfig(0);%s;endfig;",document.sample_mp_graphic))
+  local str = result.fig[1]:postscript()
+  str = str:gsub("%%BeginProlog.-%%EndProlog","%% <<stripped preamble was here>>")
+  tex.sprint(tex.ctxcatcodes,"\\starttyping\n")
+  tex.sprint((str:gsub("[\n\r]$","")))
+  tex.sprint("\\stoptyping")
+end
+\stopluacode
+\stopbuffer
+
+\getbuffer
+
+The most prominent code here concerns the path. The numbers in brackets define
+the transformation matrix for the pen we used. The \PDF\ variant looks as follows:
+
+\startbuffer
+\startluacode
+do
+  local mpx = metapost.format("metafun")
+  local result = mpx:execute(string.format("beginfig(0);%s;endfig;",document.sample_mp_graphic))
+  local list = metapost.pdfliterals(result)
+  tex.sprint(tex.ctxcatcodes,"\\starttyping")
+  tex.sprint(table.concat(list,"\n"))
+  tex.sprint("\\stoptyping")
+end
+\stopluacode
+\stopbuffer
+
+\getbuffer
+
+The operators don't look much different from the \POSTSCRIPT, which is
+mostly due to the fact that in the \POSTSCRIPT\ code, the preamble
+defines shortcuts like \type {c} for \type {curveto}.  Again, most code
+involves the path. However, this time the numbers are different and
+the transformation comes before the path.
+
+In the case of \PDF\ output, we could use \TEX\ itself to do the
+conversion: a generic converter is implemented in \type
+{supp-pdf.tex}, while a converter optimized for \CONTEXT\ \MKII\ is
+defined in the files whose names start with \type {meta-pdf}.  But in
+\CONTEXT\ \MKIV\ we use \LUA\ code for the conversion instead. Thanks to
+\LUA's powerful \LPEG\ parsing library, this gives cleaner code and is
+also faster. This converter currently lives in \type {mlib-pdf.lua}.
+
+Now, with the embedded \METAPOST\ library, conversion goes different
+still because now it is possible to request the drawn result and
+associated information in the form of \LUA\ tables.
+
+\startbuffer
+\startluacode
+do
+  local mpx = metapost.format("metafun")
+  local result = mpx:execute(string.format("beginfig(0);%s;endfig;",document.sample_mp_graphic))
+  local str = table.serialize(metapost.totable(result), "figure")
+  tex.sprint(tex.ctxcatcodes,"\\starttyping")
+  tex.sprint((str:gsub("[\n\r]$","")))
+  tex.sprint("\\stoptyping")
+end
+\stopluacode
+\stopbuffer % $<-emacs font-lock
+
+% \startsimplecolumns[n=3,width=18.5cm]
+% \getbuffer
+% \stopsimplecolumns
+
+\getbuffer
+
+This means that instead of parsing \POSTSCRIPT\ output, we now can operate on
+a proper datastructure and get code like the following:
+
+\starttyping
+function convertgraphic(result)
+  if result then
+    local figures = result.fig
+    if figures then
+      for fig in ipairs(figures) do
+        local llx, lly, urx, ury = unpack(fig:boundingbox())
+        if urx > llx then
+          startgraphic(llx, lly, urx, ury)
+          for object in ipairs(fig:objects()) do
+            if object.type == "..." then
+              ...
+              flushgraphic(...)
+              ...
+            else
+              ...
+            end
+          end
+          finishgraphic()
+        end
+      end
+    end
+  end
+end
+\stoptyping
+
+Here \type {result} is what the library returns when one or more
+graphics are processed. As you can deduce from this snippet, a
+result can contain multiple figures. Each figure corresponds with a
+\type {beginfig} \type {...} \type {endfig}. The graphic operators that
+the converter generates (so called \PDF\ literals) have to be
+encapsulated in a proper box so this is why we have:
+
+\startitemize[packed]
+\item \type {startgraphic}: start packaging the graphic
+\item \type {flushgraphic}: pipe literals to \TEX
+\item \type {finishgraphic}: finish packaging the graphic
+\stopitemize
+
+It does not matter what number you passed to \type {beginfig}, the
+graphics come out in the natural order.
+
+Little over half a dozen different object types are possible. The example
+\METAPOST\ \type{draw} command from above results in an \type {outline} object.
+This object contains not only path information but also carries
+rendering data, like the color and the pen. So, in the end we will
+flush code like \type {1 M} which sets the \type {miterlimit} to one
+or \type {.5 g} which sets the color to 50\% gray, in addition to a
+path.
+
+Because objects are returned in a way that closely resembles a
+\METAPOST's internals, some extra work needs to be done in order to
+calculate paths with elliptical pens. An example of a helper function
+in somewhat simplified form is shown next:
+
+\starttyping
+function pen_characteristics(object)
+  local p = object.pen[1]
+  local wx, wy, width
+  if p.right_x == p.x_coord and p.left_y == p.y_coord then
+    wx = abs(p.left_x  - p.x_coord)
+    wy = abs(p.right_y - p.y_coord)
+  else -- pyth: sqrt(a^2 +b^2)
+    wx = pyth(p.left_x - p.x_coord, p.right_x - p.x_coord)
+    wy = pyth(p.left_y - p.y_coord, p.right_y - p.y_coord)
+  end
+  if wy/coord_range_x(object.path, wx) >=
+                    wx/coord_range_y(object.path, wy) then
+    width = wy
+  else
+    width = wx
+  end
+  local sx, sy = p.left_x, p.right_y
+  local rx, ry = p.left_y, p.right_x
+  local tx, ty = p.x_coord, p.y_coord
+  if width ~= 1 then
+    if width == 0 then
+      sx, sy = 1, 1
+    else
+      rx, ry, sx, sy = rx/width, ry/width, sx/width, sy/width
+    end
+  end
+  if abs(sx) < eps then sx = eps end
+  if abs(sy) < eps then sy = eps end
+  return sx, rx, ry, sy, tx, ty, width
+end
+\stoptyping
+
+If \type {sx} and \type {sy} are 1, there is no need to transform
+the path, otherwise a suitable transformation matrix is calculated
+and returned. The function itself uses a few helpers that make the
+calculations even more obscure. This kind of code does not fall in
+the category trivial and as already mentioned, these basic
+algorithms were derived from the \METAPOST\ sources. Even so,
+these snippets demonstrate that interfacing using \LUA\ does not
+look that bad.
+
+In the actual \MKIV\ code things look a bit different because it does
+a bit more and uses optimized code. There you will also find the code
+dealing with the actual transformation, of which these helpers are
+just a portion.
+
+If you compare the \POSTSCRIPT\ and the \PDF\ code you will notice
+that the paths looks different. This is because the use and
+application of a transformation matrix in \PDF\ is different from how
+it is handled in \POSTSCRIPT. In \PDF\ more work is assumed to be
+done by the \PDF\ generating application. This is why in both the
+\TEX\ and the \LUA\ based converters you will find transformation code
+and the library follows the same pattern. In that respect \PDF\
+differs fundamentally from \POSTSCRIPT.
+
+Within the \TEX\ based converter there was the problem of keeping the
+needed calculations within \TEX's accuracy, which fortunately permits
+larger values that \METAPOST\ can produce. This plus the parsing code
+resulted in a not-that-easy to follow bunch of \TEX\ code.  The \LUA\
+based parser is more readable, but since it also operates on
+\POSTSCRIPT\ code it is kind of unnatural too, but at least there are
+less problems with keeping the calculations sane. The \MPLIB\ based
+converter is definitely the cleanest and least sensitive to future
+changes in the \POSTSCRIPT\ output. Does this mean that there is no
+ugly code left? Alas, as we will see in the next section, dealing with
+extensions is still somewhat messy. In practice users will not be
+bothered with such issues, because writing a converter is a one time
+job by macro package writers.
+
+\subject{extensions}
+
+In \METAFUN, which is the \METAPOST\ format used with \CONTEXT,
+a few extensions are provided, like:
+
+\startitemize[packed]
+\item cmyk, spot and multitone colors
+\item including external graphics
+\item lineair and circulair shades
+\item texts converted to outlines
+\item inserting arbitrary texts
+\stopitemize
+
+Until now, most of these extensions have been implemented by using
+specially coded colors and by injecting so called specials (think of
+them as comments) into the output. On one of our trips to a \TEX\
+conference, we discussed ways to pass information along with
+paths and eventually we arrived at associating text strings with paths
+as a simple and efficient solution.  As a result, recently \METAPOST\
+was extended by \type {withprescript} and \type {withpostscript}
+directives. For those who are unfamiliar with these new scripts,
+they are used as follows:
+
+\starttyping
+draw fullcircle withprescript "hello" withpostscript "world" ;
+\stoptyping
+
+In the \POSTSCRIPT\ output these scripts end up before and after the
+path, but in the \PDF\ converter they can be overloaded to implement
+extensions, and that works reasonably well.  However, at the moment
+there cannot be multiple pre- and postscripts associated with a single
+path inside the \METAPOST\ internals. This means that for the moment,
+the scripts mechanism is only used for a few of the extensions.
+Future versions of \MPLIB\ may provide more sophisticated methods
+for carrying information around.
+
+The \MKIV\ conversion mechanism uses scripts for graphic inclusion,
+shading and text processing but unfortunately cannot use them for
+more advanced color support.
+
+A nasty complication is that the color spaces in \METAPOST\ don't
+cast, which means that one cannot assign any color to a color
+variables: each colorspace has it's own type of variable.
+
+\starttyping
+color     one ; one := (1,1,0)   ; % correct
+cmykcolor two ; two := (1,0,0,1) ; % correct
+one := two ; % error
+fill fullcircle scaled 1cm withcolor .5[one,two] ; % error
+\stoptyping
+
+In \CONTEXT\ we use constructs like this:
+
+\starttyping
+\startreusableMPgraphic{test}
+  fill fullcircle scaled 1cm withcolor \MPcolor{mycolor} ;
+\stopreusableMPgraphic
+
+\reuseMPgraphic{test}
+\stoptyping
+
+Because \type {withcolor} is clever enough to understand what color
+type it receives, this is ok, but how about:
+
+\starttyping
+\startreusableMPgraphic{test}
+  color c ; c := \MPcolor{mycolor} ;
+  fill fullcircle scaled 1cm withcolor c ;
+\stopreusableMPgraphic
+\stoptyping
+
+Here the color variable only accepts an \RGB\ color and because in
+\CONTEXT\ there is mixed color space support combined with
+automatic colorspace conversions, it doesn't know in advance what type
+it is going to get. By implementing color spaces other than \RGB\
+using special colors (as before) such type mismatches can be avoided.
+
+The two techniques (coding specials in colors and pre|/|postscripts)
+cannot be combined because a script is associated with a path and
+cannot be bound to a variable like \type{c}. So this again is an argument
+for using special colors that remap onto \CMYK\, spot or
+multi|-|tone colors.
+
+Another area of extensions is text. In previous versions of
+\CONTEXT\ the text processing was already isolated: text ended
+up in a separate file and was processed in an separate run. More
+recent versions of \CONTEXT\ use a more abstract model of boxes that
+are preprocessed before a run, which avoids the external run(s). In
+the new approach everything can be kept internal. The conversion
+even permits constructs like:
+
+\starttyping
+for i=1 upto 100 :
+  draw btex oeps etex rotated i ;
+endfor ;
+\stoptyping
+
+but since this construct is kind of obsolete (at least in the library
+version of \METAPOST) it is better to use:
+
+\starttyping
+for i=1 upto 100 :
+  draw textext("cycle " & decimal i) rotated i ;
+endfor ;
+\stoptyping
+
+Internally a trial pass is done so that indeed 100 different texts will
+be drawn. The throughput of texts is so high that in practice one will
+not even notice that this happens.
+
+Dealing with text is yet another example of using \LPEG. The following
+snippet of code sheds some light on how text in graphics is dealt with.
+Actually this is a variation on a previous implementation. That one
+was slightly faster but looked more complex. It was also not robust for
+complex texts defined in macros in a format.
+
+\starttyping
+local P, S, V, Cs = lpeg.P, lpeg.S, lpeg.V, lpeg.Cs
+
+local btex    = P("btex")
+local etex    = P(" etex")
+local vtex    = P("verbatimtex")
+local ttex    = P("textext")
+local gtex    = P("graphictext")
+local spacing = S(" \n\r\t\v")^0
+local dquote  = P('"')
+
+local found = false
+
+local function convert(str)
+  found = true
+  return "textext(\"" .. str .. "\")"
+end
+local function ditto(str)
+  return "\" & ditto & \""
+end
+local function register()
+  found = true
+end
+
+local parser = P {
+    [1] = Cs((V(2)/register + V(3)/convert + 1)^0),
+    [2] = ttex + gtex,
+    [3] = (btex + vtex) * spacing *
+                Cs((dquote/ditto + (1-etex))^0) * etex,
+}
+
+function metapost.check_texts(str)
+  found = false
+  return parser:match(str), found
+end
+\stoptyping
+
+If you are unfamiliar with \LPEG\ it may take a while to see what
+happens here: we replace the text between \type {btex} and \type {etex}
+by a call to \type {textext}, a macro. Special care is given to
+embedded double quotes.
+
+When text is found, the graphic is processed two times. The definition
+of \type {textext} is different for each run. The first run we have:
+
+\starttyping
+vardef textext(expr str) =
+    image (
+        draw unitsquare
+            withprescript "tf"
+            withpostscript str ;
+    )
+enddef ;
+\stoptyping
+
+After the first run the result is not really converted, but just
+the outlines with the \type {tf} prescript are filtered. In the
+loop over the object there is code like:
+
+\starttyping
+local prescript = object.prescript
+if prescript then
+  local special = metapost.specials[prescript]
+  if special then
+    special(object.postscript,object)
+  end
+end
+\stoptyping
+
+Here, \type {metapost} is just the namespace used by the
+converter. The prescript tag \type {tf} triggers a function:
+
+\starttyping
+function metapost.specials.tf(specification,object)
+  tex.sprint(tex.ctxcatcodes,format("\\MPLIBsettext{%s}{%s}",
+    metapost.textext_current,specification))
+  if metapost.textext_current < metapost.textext_last then
+    metapost.textext_current = metapost.textext_current + 1
+  end
+  ...
+end
+\stoptyping
+
+Again, you can forget about the details of this function. Important is
+that there is a call out to \TEX\ that will process the text. Each snippet
+gets the number of the box that holds the content. The macro that is
+called just puts stuff in a box:
+
+\starttyping
+\def\MPLIBsettext#1#2%
+  {\global\setbox#1\hbox{#2}}
+\stoptyping
+
+In the next processing cycle of the \METAPOST\ code, the \type {textext}
+macro does something different :
+
+\starttyping
+vardef textext(expr str) =
+    image (
+        _tt_n_ := _tt_n_ + 1 ;
+        draw unitsquare
+            xscaled _tt_w_[_tt_n_]
+            yscaled (_tt_h_[_tt_n_] + _tt_d_[_tt_n_])
+            withprescript "ts"
+            withpostscript decimal _tt_n_ ;
+    )
+enddef ;
+\stoptyping
+
+This time the by then known dimensions of the box that is used to
+store the snippet are used. These are stored in the \type {_tt_w_},
+\type {_tt_h_} and \type {_tt_d_} arrays. The arrays are defined by
+\LUA\ using information about the boxes, and passed to the library
+before the second run. The result from the second \METAPOST\ run
+is converted, and again the prescript is used as trigger:
+
+\starttyping
+function metapost.specials.ts(specification,object,result)
+    local op = object.path
+    local first, second, fourth  = op[1], op[2], op[4]
+    local tx, ty = first.x_coord      , first.y_coord
+    local sx, sy = second.x_coord - tx, fourth.y_coord - ty
+    local rx, ry = second.y_coord - ty, fourth.x_coord - tx
+    if sx == 0 then sx = 0.00001 end
+    if sy == 0 then sy = 0.00001 end
+    metapost.flushfigure(result)
+    tex.sprint(tex.ctxcatcodes,format(
+        "\\MPLIBgettext{%f}{%f}{%f}{%f}{%f}{%f}{%s}",
+        sx,rx,ry,sy,tx,ty,metapost.textext_current))
+    ...
+end
+\stoptyping
+
+At this point the converter is actually converting the graphic and
+passing \PDF\ literals to \TEX. As soon as it encounters a text,
+it flushes the \PDF\ code collected so far and injects some \TEX\
+code. The \TEX\ macro looks like:
+
+\starttyping
+\def\MPLIBgettext#1#2#3#4#5#6#7%
+  {\ctxlua{metapost.sxsy(\number\wd#7,\number\ht#7,\number\dp#7)}%
+   \pdfliteral{q #1 #2 #3 #4 #5 #6 cm}%
+   \vbox to \zeropoint{\vss\hbox to \zeropoint
+     {\scale[sx=\sx,sy=\sy]{\raise\dp#7\box#7}\hss}}%
+   \pdfliteral{Q}}
+\stoptyping
+
+Because text can be transformed, it needs to be scale back to the right
+dimensions, using both the original box dimensions and the transformation
+of the unitquare associated with the text.
+
+\starttyping
+local factor = 65536*(7200/7227)
+
+function metapost.sxsy(wd,ht,dp) -- helper for text
+  commands.edef("sx",(wd ~= 0 and 1/( wd    /(factor))) or 0)
+  commands.edef("sy",(wd ~= 0 and 1/((ht+dp)/(factor))) or 0)
+end
+\stoptyping
+
+So, in fact there are the following two processing alternatives:
+
+\startitemize[packed]
+\item tex: calls a \LUA\ function that processed the graphic
+\item lua: parse the \METAPOST\ code for texts and decide if two
+      runs are needed
+\stopitemize
+
+Now, if there was no text to be found, the continuation is:
+
+\startitemize[packed]
+\item lua: process the code using the library
+\item lua: convert the resulting graphic (if needed) and check
+      if texts are used
+\stopitemize
+
+Otherwise, the next steps are:
+
+\startitemize[packed]
+\item lua: process the code using the library
+\item lua: parse the resulting graphic for texts (in the postscripts)
+      and signal \TEX\ to process these texts afterwards
+\item tex: process the collected text and put the result in boxes
+\item lua: process the code again using the library but this time let
+      the unitsquare be transformed using the text dimensions
+\item lua: convert the resulting graphic and replace the transformed
+      unitsquare by the boxes with text
+\stopitemize
+
+The processor itself is used in the \MKIV\ graphic function that takes
+care of the multiple passes mentioned before. To give you an idea of
+how it works, here is how the main graphic processing function roughly
+looks.
+
+\starttyping
+local current_format, current_graphic
+
+function metapost.graphic_base_pass(mpsformat,str,preamble)
+    local prepared, done = metapost.check_texts(str)
+    metapost.textext_current = metapost.first_box
+    if done then
+        current_format, current_graphic = mpsformat, prepared
+        metapost.process(mpsformat, {
+            preamble or "",
+            "beginfig(1); ",
+            "_trial_run_ := true ;",
+            prepared,
+            "endfig ;"

+        tex.sprint(tex.ctxcatcodes,
+            "\\ctxlua{metapost.graphic_extra_pass()}")
+    else
+        metapost.process(mpsformat, {
+            preamble or "",
+            "beginfig(1); ",
+            "_trial_run_ := false ;",
+            str,
+            "endfig ;"
+        } )
+    end
+end
+
+function metapost.graphic_extra_pass()
+    metapost.textext_current = metapost.first_box
+    metapost.process(current_format, {
+        "beginfig(0); ",
+        "_trial_run_ := false ;",
+        table.concat(metapost.texttextsdata()," ;\n"),
+        current_graphic,
+        "endfig ;"
+    })
+end
+\stoptyping
+
+The box information is generated as follows:
+
+\starttyping
+function metapost.texttextsdata()
+    local t, n = { }, 0
+    for i = metapost.first_box, metapost.last_box do
+        n = n + 1
+        local box_i = tex.box[i]
+        if box_i then
+            t[#t+1] = format(
+                "_tt_w_[%i]:=%f;_tt_h_[%i]:=%f;_tt_d_[%i]:=%f;",
+                n, box_i.width /factor,
+                n, box_i.height/factor,
+                n, box_i.depth /factor
+            )
+        else
+            break
+        end
+    end
+    return t
+end
+\stoptyping
+
+This is a typical example of accessing information available inside
+\TEX\ from \LUA, in this case information about boxes.
+
+The \type {trial_run} flag is used at the \METAPOST\ end, in fact the
+\type {textext} macro looks as follows:
+
+\starttyping
+vardef textext(expr str) =
+    if _trial_run_ :
+        % see first variant above
+    else :
+        % see second variant above
+    fi
+enddef ;
+\stoptyping
+
+This trickery is not new. We used it already in \CONTEXT\ for some
+time, but until now the multiple runs took way more time and from
+the perspective of the user this all looked much more complex.
+
+It may not be that obvious, but: in the case of a trial run (for
+instance when texts are found), after the first processing stage,
+and during the parsing of the result, the commands that typeset the
+content will be printed to \TEX. After processing, the command to do
+an extra pass is printed to \TEX\ also. So, once control is passed
+back to \TEX, at some point \TEX\ itself will pass control back to
+\LUA\ and do the extra pass.
+
+The base function is called in:
+
+\starttyping
+function metapost.graphic(mpsformat,str,preamble)
+    local mpx = metapost.format(mpsformat or "metafun")
+    metapost.graphic_base_pass(mpx,str,preamble)
+end
+\stoptyping
+
+The \type {metapost.format} function is part of \type {mlib-run}.
+It loads the \type{metafun} format, possibly after (re|)|generating it.
+
+Now, admittedly all this looks a bit messy, but in pure \TEX\ macros
+it would be even more so. Sometime in the future, the postponed calls to
+\tex{ctxlua} and the explicit \tex{pdfliteral}s can and will be
+replaced by using direct node generation, but that requires a rewrite
+of the internal \LUATEX\ support for \PDF\ literals.
+
+The snippets are part of the \type {mlib-*} files of \MKIV. These files are
+tagged as experimental and will stay that way for a while yet. This is
+proved by the fact that by now we use a slightly different approach.
+
+Summarizing the impact of \MPLIB\ on extensions, we can conclude that
+some are done better and some more or less the same. There are some
+conceptual problems that prohibit using pre- and postscripts for
+everything (at least currently).
+
+\subject{integrating}
+
+The largest impact of \MPLIB\ is processing graphics at runtime.
+In \MKII\ there are two methods: real runtime processing (each
+graphic triggered a call to \METAPOST) and collective processing
+(between \TEX\ runs). The first method slows down the \TEX\ run,
+the second method generates a whole lot of intermediate \POSTSCRIPT\
+files. In both cases there is a lot of file \IO\ involved.
+
+In \MKIV, the integrated library is capable of processing
+thousands of graphics per second, including conversion. The
+preliminary tests (which involved no extensions) involved graphics
+with 10 random circles drawn with penshapes in random colors, and
+the thoughput was around 2000 such graphics per second on a
+2.3 MHz Core Duo:
+
+\startlinecorrection[blank]
+\hbox to \textwidth{\strut\dorecurse{5}{\startMPcode
+numeric w ; w := \the\textwidth/6 ;
+for k:=1 upto 10 :
+    draw fullcircle
+        scaled uniformdeviate(w)
+        withpen pencircle xscaled (w/20) yscaled (w/40) rotated 30
+        withcolor (red/(k/4)) ;
+endfor ;
+setbounds currentpicture to fullsquare scaled w ;
+\stopMPcode\hss}\unskip}
+\stoplinecorrection
+
+In practice there will be some more overhead involved than in the
+tests. For instance, in \CONTEXT\ information about the current state
+of \TEX\ has to be passed on also: page dimensions, font information,
+typesetting related parameters, preamble code, etc.
+
+The whole \TEX\ interface is written around one process function:
+
+\starttyping
+metapost.graphic(metapost.format("metafun"),"mp code")
+\stoptyping
+
+optionally a preamble can be passed as the third argument.
+This one function is used in several other macros, like:
+
+\starttyping
+\startMPcode                  ... \stopMPcode
+\startMPpage                  ... \stopMPpage
+\startuseMPgraphic     {name} ... \stopuseMPgraphic
+\startreusableMPgraphic{name} ... \stopreusableMPgraphic
+\startuniqueMPgraphic  {name} ... \stopuniqueMPgraphic
+
+\useMPgraphic{name}
+\reuseMPgraphic{name}
+\uniqueMPgraphic{name}
+\stoptyping
+
+The user interface is downward compatible: in \MKIV\ the same
+top-level commands are provided as in \MKII. However, the
+(previously required) configuration macros and flags are obsolete.
+
+This time, the conclusion is that the impact on \CONTEXT\ is immense:
+The code for embedding graphics is very clean, and the running time
+for graphics inclusion is now negligible. Support for text in graphics is
+more natural now, and takes no runtime either (in \MKII\ some
+parsing in \TEX\ takes place, and if needed long lines are split;
+all this takes time).
+
+In the styles that \PRAGMA\ uses internally, there is support for the
+generation of placeholders for missing graphics. These placeholders
+are \METAPOST\ graphics that have some 60 randomly scaled circles with randomized
+colors. The time involved in generating 50 such graphics is (on Hans'
+machine) some 14 seconds, while in \LUATEX\ only half a second is needed.
+
+\startlinecorrection[blank]
+\hbox to \textwidth \bgroup
+\hss\dorecurse{4}{\externalfigure[dummy][width=.2\textwidth]\hss}%
+\egroup
+\stoplinecorrection
+
+Because \LUATEX\ needs more startup time and deals with larger fonts
+resources, \PDFTEX\ is generally faster, but now that we have \MPLIB,
+\LUATEX\ suddenly is the winner.
+
+% We end this article by showing a few graphics. \CONTEXT\ ships with a module
+% that permits tracking of resource usage. Users can add the following line
+% to their document:
+
+% \starttyping
+% \usemodule[timing]
+% \stoptyping

+% \ShowNamedUsage{\jobname-luatex-progress}{glyph}{elapsed_time}
+% \stoptyping
+
+% In this document, \LUA\ memory usage is as follows. The blue lines
+% represent runtime, on Hans' machine some 3.5 seconds, including
+% startuptime, which clearly shows in the graphic. Keep in mind that
+% garbage collection only happens at certain moment, so \LUA\ memory
+% usage is normally a sawtooth graphic. The horizontal axis reflects the
+% number of pages.
+
+% \startlinecorrection[blank]
+% \ShowNamedUsage{\jobname-luatex-progress}{luastate_bytes}{elapsed_time}

+% to store data as well.
+
+% \startlinecorrection[blank]
+% \ShowNamedUsage{\jobname-luatex-progress}{dyn_used}{elapsed_time}
+% \stoplinecorrection
+
+% Currently we use \type {\pdfliteral}, which means that all

+% graphics this can be a real memory hog.
+
+% Unfortunately not all this memory is freed, so eventually Hartmut

+
+Getting the 1.06 release of Latin Modern out in the wild took some discussion and
+testing. Not only were the names (internal names as well as file names) changed in
+such a way that multiple paplications could deal with it, but also some more
+advanced ligature trickery was added.

+that you can never depend on it.
+
+\section {Herds}
+
+A while ago, Duane, Taco and I published the Cow Font. It's non||trivial to
+cook up a font made of cows, but of course Mojca Miklavec (who else) wants
+to typeset something Slovenian in this font. Now, the problem is that in
+\MKIV\ we don't have fallback characters, or more precisely, we don't make
+\UTF\ characters active and accent composing commands are mapped onto \UTF.
+
+This means that nothing will show up when we have no characters in the
+defined fonts. For the moment we stick to simple virtual fonts but
+because we can use node lists in virtual fonts, in the near future we will
+cook up a way to create arbitrary fallback characters.
+
+The following example demonstrates how to \quote {complete} a font that misses
+glyphs.

+\chapter {Nodes and attributes}
+
+\subject{introduction}
+
+Here we will tell a bit about the development of node access in \LUATEX. We
+will also introduce attributes, a feature closely related to nodes. We assume
+that you are somewhat familiar with \TEX's nodes: glyphs, kerns, glue, penalties,
+whatsits and friends.
+
+\subject{tables}
+
+Access to node lists has been implemented rather early in the development because
+we needed it to fulfil the objectives of the Oriental \TEX\ project.  The first
+implementation used nested tables, indexed by number. In that approach, the first
+entry in each node indicated the type in string format. At that time a horizontal
+list looked as follows:
+
+\starttyping
+list = {
+    [1] = "hlist",
+    [2] = 0,
+    ...
+    [8] = {
+        [1] = {
+            [1] = "glyph",
+            ...
+        },
+        [2] = {
+            ...
+        }
+}
+\stoptyping
+
+Processing such lists is rather convenient since we can use the normal table
+iterators. Because in practice only a few entries of a node are accessed, working
+with numbers is no real problem: in slot~1 we have the type, en in the
+case of a horizontal or vertical list, we know that slot~8 is either empty or
+a table. Looping over the list is done with:
+
+\starttyping
+for i, node in ipairs(list) do
+    if node[1] == "glyph" then
+        list[i][5] = string.byte(string.upper(string.char(node[5])))
+    end
+end
+\stoptyping
+
+Node processing code hooks into the box packagers and paragraph builder and
+a few more places. This means that when using the table approach a lot of
+callbacks take place where \TEX\ has to convert to and from \LUA. Apart from
+processing time, we also have to deal with garbage collection then and on an older
+machine with insufficient memory interesting bottlenecks show up. Therefore some
+following optimizations were implemented at the \TEX\ end of the game.
+
+Side note concerning speed: when memory of processing speed is low, runtime can
+increase five to tenfold compared to \PDFTEX\ when one does intensive node
+manipulations. This is due to garbage collection at the \LUA\ end and memory
+(de)allocation at the \TEX\ end. There is not much we can do about that. Interfacing
+has a price and hardware is more powerful than when \TEX\ was written. Processing
+the \TEX\ book using no callbacks is not that much slower than using a traditional
+\TEX\ engine. However, nowadays fonts are more extensive, demands for special
+features more pressing and that comes at a price.
+
+When the list is not changed, the callback function can return the value \type
+{true}. This signals \TEX\ that it can keep the original list. When the list is
+empty, the callback function can return the value \type {false}. This signals
+\TEX\ that the list can be discarded.
+
+In order to minimize conversions and redundant processing, nested lists were
+not passed as table but as a reference. One could expand such a list when
+needed. For instance, when one hooks the same function in the \type
+{hpack_filter} and \type {pre_linebreak_filter} callbacks, this way one can be
+pretty sure that each node is only processed once. Boxed material that is part
+of the paragraph stream first enters the box packers and then already is
+processed before it enters the paragraph callback. Of course one can decide the
+expand the referred sublist and process it again. Keep in mind that we're still
+talking of a table approach, but we're slowly moving away from big conversions.
+
+In principle one can insert and delete nodes in such a list but given that
+the average length of a list representing a page is around 4000, you can
+imagine that moving around a large amount of data is not that efficient. In order
+to cope with this, we experimented a lot and came to solutions which will be
+discussed later on.
+
+At the \LUA\ end some tricks were used to avoid the mentioned insertion and
+deletion penalty. When a node was deleted, we simply set its value to \type
+{false}. Deleting all glyphs then became:
+
+\starttyping
+for i, node in ipairs(list) do
+    if node[1] == "glyph" then
+        list[i] = false
+    end
+end
+\stoptyping
+
+When \TEX\ converted a \LUA\ table back into its internal representation, it
+ignored such false nodes.
+
+For insertion a dummy node was introduced at the \LUA\ end. The next code
+duplicates the glyphs.
+
+\starttyping
+for i, node in ipairs(list) do
+    if node[1] == "glyph" then
+        list[i] = { 'inline', 0, nil, { node, node } }
+    end
+end
+\stoptyping
+
+Just before we passed the resulting list back to \TEX\ we collapsed these
+inline pseudo nodes. This was a rather fast operation.
+
+So far so good. But then we introduced attributes and keeping track of them
+as well as processing them takes quite some processing power. Nodes with
+attributes then looked like:
+
+\starttyping
+someglyph = {
+    [1] = "glyph",               -- type
+    [2] = 0,                     -- subtype
+    [3] = { [1] = 5, [4] = 10 }, -- attributes
+    [4] = 88,                    -- slot
+    [5] = 32                     -- font
+}
+\stoptyping
+
+Constructing attribute tables for each node is costly in terms of memory usage
+and processing time and we found out that the garbage collector was becoming
+a bottleneck, especially when resources are thin. We will go into more detail
+about attributes elsewhere.
+
+\subject{lists}
+
+At the same time that we discussed these issues, new Dutch word lists (adapted
+spelling) were published and we started wondering if we could use such lists
+directly for hyphenation purposes instead of relying on traditional patterns. Here
+the first observation was that handling these really huge lists is no problem at
+all. Okay, it costs some memory but we only need to load one of maybe a few of
+these lists. Hyphenating a paragraph using tables with hyphenated words and
+processing the paragraph related node list is not only fast, it also gives us the
+opportunity to cross font boundaries. Of course there are kerns and ligatures to
+deal with but this is no big deal. At least it can be an alternative or addendum
+to the current hyphenator. Some languages have very small pattern files or a very
+systematic approach to hyphenation so there is no reason to abandon the traditional
+ways in all cases. Take your choice.
+
+When experimenting with the new implementation we tested the performance by letting
+\LUA\ take care of hyphenation, spell checking (marking words) and adding
+inter||character kerns. When playing with big lists of words we found out that the
+caching mechanism could not be used due to some limitations in the \LUA\ byte code
+interpreter, so eventually we ended up with a dedicated loader.
+
+However, again we ran into performance problems when lists became more complex. And so,
+instead of converting \TEX\ datastructures into \LUA\ tables userdata types came into
+view. Taco already had reimplemented the node memory management, so a logical next step
+was to reimplement the callbacks and box related code to deal with nodes as linked lists.
+Since this is now the fashion in \LUATEX, you may forget the previous examples, although
+it is not that hard to introduce table representations again once we need them.
+
+Of course this resulted in an adaption to the regular \TEX\ code but a nice side effect
+was that we could now use fields instead of indexes into the node data structure. There
+is a small price to pay in terms of performance, but this can be compensated by clever
+programming.
+
+\starttyping
+someglyph = {
+    type = 41,
+    subtype = 0,
+    attributes = <attributes>,
+    char = 88,
+    font = 32
+}
+\stoptyping
+
+Attributes themselves are userdata. The same is true for components that are present
+when we're for instance dealing with ligatures.
+
+As you can see, in the field variant, a type is a number. In practice, because \LUA\
+hashes strings, working with strings is as fast when comparing, but since we now have
+the more abstract type indicator, we stick with the numbers, which saves a few conversions.
+When dealing with tables we get code like:
+
+\starttyping
+function loop_over_nodes(list)
+    for i, n in ipairs(list)
+        local kind = n[1]
+        if kind == "hlist" or kind == "vlist" then
+            ...
+        end
+    end
+end
+\stoptyping
+
+But now that we have linked lists, we get the following. Node related methods
+are available in the \type {node} namespace.
+
+\starttyping
+function loop_over_nodes(head)
+    local hlist, vlist = node.id('hlist'), node.id('vlist')
+    while head do
+        local kind = head.type
+        if kind == hlist or kind == vlist then
+            ...
+        end
+        head = head.next
+    end
+end
+\stoptyping
+
+Using an abstraction (i.e.\ a constant representing \type {hlist} looks
+nice here, which is why numbers instead of strings are used. The indexed
+variant is still supported and there we have strings.
+
+Going from a node list (head node) to a table is not that complex. Sometimes
+this can be handy because manipulating tables is more convenient that messing
+around with userdata when it comes down to debugging or tracing.
+
+\starttyping
+function nodes.totable(n)
+    function totable(n)
+        local f, tt = node.fields(n.id,n.subtype), { }
+        for _,v in ipairs(f) do
+            local nv = n[v]
+            if nv then
+                local tnv = type(nv)
+                if tnv == "string" or tnv == "number" then
+                    tt[v] = nv
+                else -- userdata
+                    tt[v] = nodes.totable(nv)
+                end
+            end
+        end
+        return tt
+    end
+    local t = { }
+    while n do
+        t[#t+1] = totable(n)
+        n = n.next
+    end
+    return t
+end
+\stoptyping
+
+It will be clear that here we collect data in \LUA\ while treating nodes
+as userdata keeps most of it at the \TEX\ side and this is where the gain in
+speed comes from.
+
+\subject{side effects}
+
+While experimenting with node lists Taco and I ran into a peculiar side effect.
+One of the tests involved adding kerns between glyphs (inter character spacing
+as sometimes uses in titles in a large print). When applied to a whole document
+we noticed that at some places (words) the added kerning was gone. We used
+the subtype zero kern (which is most efficient) and in the process of hyphenating
+\TEX\ removes these kerns and inserts them later (but then based on the
+information stored in the font.
+
+The reason why \TEX\ removes the font related kerns, is the following. Consider
+the code:
+
+\starttyping
+\setbox0=\hbox{some text} the text \unhcopy0 has width \the\wd0
+\stoptyping
+
+While constructing the \type {\hbox}, \TEX\ will apply kerning as dictated
+by the font. Otherwise the width of the box would not be correct. This means
+that the node list entering the linebreak machinery contains such kerns.
+Because hyphenating works on words \TEX\ will remove these kerns in the
+process of identifying the words. It creates a string, removes the original
+sequence of nodes, determines hyphenation points, and add the result to
+the node list.  For efficiency reasons \TEX\ will only look at places
+where hyphenation makes  sense.
+
+Now, imagine that we add those kerns in the callback. This time, all characters
+are surrounded by kerns (which we gave subtype zero). When \TEX\ is determining
+feasable breakpoints (hyphenation), it will remove those kerns, but only at
+certain places. Because our kerns are way larger than the normal interglyph
+kerns, we suddenly end up with an intercharacter spaced paragraph that has
+some words without such spacing but the font dictated kerns.
+
+\blank
+m o s t\quad w o r d s\quad a r e\quad s p a c e d\quad b u t\quad
+some words\quad a r e\quad n o t
+\blank
+
+Of course a solution is to use a different kern, but at least this shows that
+the moment of processing nodes as well as the kind of manipulations need
+to be chosen with care.
+
+Kerning is a nasty business anyway. Imagine the following word:
+
+\starttyping
+effe
+\stoptyping
+
+When typeset this turns into three characters, one of them being a ligature.
+
+\starttyping
+[char e] [liga ff (components f f)] [char e]
+\stoptyping
+
+However, in Dutch, such a word hyphenates as:
+
+\starttyping
+ef-fe
+\stoptyping
+
+This means that in the node list we eventually find something:
+
+\starttyping
+[char e] [disc (f-) (f) (skip 1)] [liga ff (components f f)] [char e]
+\stoptyping
+
+So, eventually we need to kern between the character sequences [e,f-],
+[e,ff], [ff,e] and [f,e].
+
+\subject {attributes}
+
+We now arrive at attributes, a new property of nodes. Before we explain a
+bit more what can be done with them, we show how to define a new attribute
+and toggle it. In the following example the \type {\visualizenextnodes} macro
+is part of \CONTEXT\ \MKIV.
+
+\startbuffer
+\newattribute\aa
+\newattribute\ab
+\visualizenextnodes \hbox {\aa1 T{\ab3\aa2 E}X}
+\stopbuffer
+
+\typebuffer
+
+\placefigure
+  [page]
+  []
+  {\type{\hbox {\aa1 T{\ab3\aa2 E}X \ab 4}}}
+  {\switchtobodyfont[7pt]%
+   \scale[width=.9\textwidth]{\framed
+     [offset=2ex,foregroundcolor=red]
+     {\startsimplecolumns[n=2]
+        \resetglobalattributes
+        \resetlocalattributes
+        \getbuffer
+      \stopsimplecolumns}}}
+
+For the sake of this example, we start the allocation at 2000 because we don't
+want to interfere with attributes already defined in \CONTEXT. The node list
+resulting from the box is shown at the next page. As you can see here, internally
+attributes become a linked list assigned to the \type {attr} field. This means
+that one has to do some work in order to inspect attributes.
+
+\starttyping
+function has_attribute(n,a)
+    if n and n.attr then
+        n = n.attr.next
+        while n do
+            if n.number == a then
+                return n.value
+            end
+            n = n.next
+        end
+    else
+        return false
+    end
+end
+\stoptyping
+
+The previous function can be used in tests like:
+
+\starttyping
+local total = 0
+while n do
+    if has_attribute(n,2000) then
+        total = total + 1
+    end
+    n = n.next
+end
+texio.write_nl(string.format(
+    "attribute 2000 has been seen % times", total
+))
+\stoptyping
+
+When implementing nodes and attributes we did rather extensive tests and
+one of the test documents implemented some preliminary color mechanism
+based on attributes. When handling the colors the previous function was
+called some 300.000 times and the total node processing time (which also
+involved font handling) was some 2.9 seconds. Implementing this function
+as a helper brought down node processing time to 2.4 seconds. Of course
+the gain depends on the complexity of the list (nesting) and the number
+of attributes that are set (upto 5 per node in this test). A few more helper
+functions are available, some are for convenience, some gain us some speed.
+
+The nice thing about attributes is that they obey grouping. This means that
+in the following sequence:
+
+\starttyping
+x {\aa1 x \ab2 x} x
+\stoptyping
+
+the attributes are assigned like:
+
+\starttyping
+x x(201=1) x(201=1,202=2) x
+\stoptyping
+
+Internally \LUATEX\ does some optimizations with respect to assigning
+a sequence of similar attributes, but you should keep in mind that in practice
+the memory usage will be larger when using many attributes.
+
+We played with color and other properties, hyphenation based on word lists
+(and tracking languages with attributes) and or special algorithms (url
+hyphenation), spell checking (marking words as being spelled wrongly), and
+a few more things. This involved handling attributes in several callbacks
+resulting in the insertion or deletion of nodes.
+
+When using attributes for color support, we have to insert \type {pdfliteral} whatsit
+nodes at some point depending on the current color. This also means that the
+time spent with color support at the \TEX\ end will be compensated by
+time spent at the \LUA\ side. It also means that because housekeeping to do
+with colors spanning pages and columns is gone because from now on color
+information travels with the nodes. This saves quite some ugly code.
+
+Because most of the things that we want to do with attributes (and we have
+quite an agenda) are already nicely isolated in \CONTEXT, attributes will
+find their way rather soon in \CONTEXT\ \MKIV.
+
+Let's end with an observation. Attributes themselves are not something
+revolutionary. However, if you had to deal with them in \TEX, i.e.\
+associate them with for instance actions in during shipout, quite some
+time would have been spent on getting things right. Even worse: it would
+have lead to never ending discussions in the \TEX\ community and as
+such it's no surprise that something like this never showed up. The fact that
+we can use \LUA\ and manipulate node lists in many ways frees us from
+much discussion.
+
+We are even considering in future versions of \LUATEX\ to turn font, language
+and direction related information into attributes (in some private range) so this
+story is far from finished. As a teaser, consider the following line of thinking.
+
+Currently when a character enters the machinery, it becomes a glyph node. Among
+other characteristics, this node contains information about the font and the
+slot in that font which is used to represent that character. In a similar fashion,
+a space becomes glue with a measure probably related to the current font.
+
+However, with access to nodes and attributes, you can imagine the following
+scenario. Instead of a font (internally represented by a font id), you use an
+attribute referring to a font. At that time, the font field us just pointing to
+\TEX's null font. In a pass over the node list, you resolve the character and their
+attributes to a fonts and (maybe) other characters. Spacing can be postponed as well
+and instead of real glue values we can use multipliers and again attributes point
+the way to resolve them.
+
+Of course the question is if this is worth the trouble. After all typesetting is
+about fonts and there is no real reason not to give them a special place.

+\chapter {\OPENTYPE: too open?}
+
+In this chapter I will reflect on \OPENTYPE\ from within my
+limited scope and experience. What I'm writing next is my personal
+opinion and I may be wrong in many ways.
+
+Until recently installing fonts in a \TEX\ system was not
+something that a novice user could do easily. First of all, the
+number of files involved is large:
+
+\startitemize
+
+\item If it is a bitmap font, then for each size used there is a
+\PK\ file, and this is reflected in the suffix, for instance \type
+{pk300}.
+
+\item If it is an outline font, then there is a \TYPEONE\ file
+with suffix \type {pfb} or sometimes glyphs are taken from
+\OPENTYPE\ fonts (with \type {ttf} or \type {otf} as suffix). In
+the worst case such wide fonts have to be split into smaller ones.
+
+\item Because \TEX\ needs information about the dimensions of the
+glyphs, a metric file is needed; it has the suffix \type {tfm}. There
+is limit of 256 characters per font.
+
+\item If the font lacks glyphs it can be turned into a virtual
+font and borrow glyphs from other fonts; this time the suffix is
+\type {vf}.
+
+\item If no such metric file is present, one can make one from a
+file that ships with the fonts; it has the suffix \type {afm}.
+
+\item In order to include the font in the final file, the backend
+to \TEX\ has to match glyph references to the glyph slots in the
+font file, and for that it needs an encoding vector, for
+historical reasons this is a \POSTSCRIPT\ blob in a file with
+suffix \type {enc}.
+
+\item This whole lot is associated in a map file, with suffix
+\type {map}, which couples metric files to encodings and
+to font files.
+
+\stopitemize
+
+Of course the user also needs \TEX\ code that defines the font,
+but this differs per macro package. If the user is lucky the
+distributions ships with files and definitions of his/her
+favourite fonts, but otherwise work is needed. Font support in
+\TEX\ systems has been complicated by the facts that the first
+\TEX\ fonts were not \ASCII\ complete, that a 256 limit does not
+go well with multilingual typesetting and that most fonts lacked
+glyphs and demanded drop|-|ins. Users of \CONTEXT\ could use
+the \type {texfont} program to generate metrics and map file
+for traditional \TEX\ but this didn't limit the number of files.
+
+In modern \TEX\ engines, like \XETEX\ and \LUATEX, less files are
+needed, but even then some expertise is needed to use \TYPEONE\
+fonts. However, when \OPENTYPE\ fonts are used in combination with
+\UNICODE, things become easy. The (one) fontfile needs to be
+put in a location that the \TEX\ engine knows and things
+should work.
+
+In \LUATEX\ with \CONTEXT\ \MKIV\ support for traditional
+\TYPEONE\ fonts is also simplified: only the \type {pfb} and \type
+{afm} files are needed. Currently we only need \type {tfm} files
+for math fonts but that will change too. Virtual fonts can be
+built at runtime and we are experimenting with real time font
+generation. Of course filenames are still just as messy and
+inconsistent as ever, so other tools are still needed to figure
+out the real names of fonts.
+
+So, what is this \OPENTYPE\ and will it really make \TEX ies life
+easier? The qualification \quote {open} in \OPENTYPE\ carries
+several suggestions:
+
+\startitemize
+
+\item  the format is defined in an open way, everybody can read the
+specification and what is said there is clear
+
+\item the format is open in the sense that one can add additional
+features, so there are no limits and/or limits can be shifted
+
+\item there is an open community responsible for the advance of this
+specification and commercial objectives don't interfere and/or lead
+to conflicts
+
+\stopitemize
+
+Is this true or not? Indeed the format is defined in the open
+although the formal specification is an expensive document. A free
+variant is available at the Microsoft website but it takes some
+effort to turn that into a nicely printable document. What is said
+there is quite certainly clear for the developers, but it takes quite
+some efforts to get the picture. The format is binary so one
+cannot look into the file and see what happens.
+
+The key concept is \quote {features}, which boils down to a
+collection of manipulations of the text stream based on rules laid
+down in the font. These can be simple rules, like \quote {replace
+this character by its smallcaps variant} or more complex, like
+\quote {if this character is followed by that character, replace
+both by yet another}. There are currently two classes of features:
+substitutions and (relative) positioning. One can indeed add
+features so there seem to be no limits.
+
+The specification is a hybrid of technologies developed by
+Microsoft and Adobe with some influence by Apple. These
+companies may have conflicting interests and therefore this may
+influence the openness.
+
+So, in practice we're dealing with a semi-open format, crippled by
+a lack of documentation and mostly controlled by some large
+companies. These characteristics make that developing support for
+\OPENTYPE\ is not that trivial. Maybe we should keep in mind that
+this font format is used for word processors (no focus on
+typography), desk top publishing (which permits in-situ tweaking)
+and rendering text in graphical user interfaces (where script and
+language specific rendering is more important than glyph
+variants). Depending on the use features can be ignored, or
+applied selectively, of even compensated.
+
+Anyhow, a font specification is only part of the picture. In
+order to render it useful we need support in programs that display
+and typeset text and of course we need fonts. And in order to make
+fonts, we need programs dedicated to that task too.
+
+Let's go back for a moment to traditional \TEX. A letter can be
+represented by its standard glyph or by a smallcaps variant. A
+digit can be represented by a shape that sits on the baseline, or
+one that may go below: an oldstyle numeral. Digits can have the
+same width, or be spaced proportionally. There can be special small
+shapes for super- and subscripts. In traditional \TEX\ each such
+variant demanded a font. So, say that one wants normal shapes,
+smallcaps and oldstyle, three fonts were needed and this for each
+of the styles normal, bold, italic, etc. Also a font switch is
+needed in order to get the desired shapes.
+
+In an \OPENTYPE\ universe normal, smallcaps and oldstyle shapes
+can be included in one font and they are organized in features. It
+will be clear that this will make things easier for users: if one
+buys a font, there is no longer a need to sort out what file has
+what shapes, there is no longer a reason for reencodings because
+there is no 256 limit, map files are therefore obsolete, etc.
+Only the \TEX\ definition part remains, and even that is easier
+because one file can be used in different combinations of
+features.
+
+One of the side effects of the already mentioned semi|-|open
+character of the standard is that we cannot be completely sure
+about how features are implemented. Of course one can argue that
+the specification defines what a feature is and how a font should
+obey it, but in practice it does not work out that way.
+
+\startitemize
+
+\item Nobody forces a font designer (or foundry) to implement
+features. And if a designer provides variants, they may be
+incomplete. In the transition from \TYPEONE\ to \OPENTYPE\ fonts
+may even have no features at all.
+
+\item Some advanced features, like fractions, demand extensive
+substitution rules in the font. The completeness may depend on the
+core application the font was made for, or the ambition of the
+programmer who assists the designer, or on the program that is
+used to produce the font.
+
+\item Many of the features are kind of generic, in the sense that
+they don't depend on heuristics in the typesetting program: it's
+just rules that need to be applied. However, the typesetting
+program may be written in such a way that it only recognized
+certain features.
+
+\item Some features make assumptions, for instance in the sense
+that they expect the program to figure out what the first character
+of a word is. Other features only work well if the program implements
+the dedicated machinery for it.
+
+\item Features can originate from different vendors and as a
+result programs may interpret them differently. Developers of
+programs may decide only to support certain features, even if
+similar features can be supported out of the box. In the worst
+case a symbiosis between bugs in programs and bugs in fonts
+from the same vendor can lead to pseudo standards.
+
+\item Designers (or programmers) may assume that features are
+applied selectively on a range of input, but in automated
+workflows this may not be applicable. Style designers may come up with
+specifications that cannot be matched due to fonts that have only
+quick and dirty rules.
+
+\item Features can be specific for languages and scripts. There are
+many languages and many scripts and only a few are supported. Some
+features cover similar aspects (for instance ligatures) and where
+a specific rendering ends up in the language, script, feature
+matrix is not beforehand clear.
+
+\stopitemize
+
+In some sense \OPENTYPE\ fonts are intelligent, but they are not
+programs. Take for instance the frac feature. When enabled, and
+when supported in the font, it {\em may} result in 1/2 being
+typeset with small symbols. But what about a/b? or this/that? In
+principle one can have rules that limit this feature to numerals
+only or to a simple cases with a few characters. But I have seen
+fonts that produce garbage when such a feature is applied to the
+whole text. Okay, so one should apply it selectively. But, if
+that's the way to go, we could as well have let the typesetting
+program deal with it and select superior and inferior glyphs from
+the font. In that case the program can deal with fuzzy situations
+and we're not dependent on the completeness of rules. In practice,
+at least for the kind of applications that I have for \TEX, I
+cannot rely on features being implemented correctly.
+
+For ages \TEX ies have been claiming that their documents can be
+reprocessed for years and years. Of course there are dependencies
+on fonts and hyphenation patterns, but these are relatively
+stable. However, in the case of \OPENTYPE\ we have not only
+shapes, but also rules built in. And rules can have bugs.
+Because fonts vendors don't provide automated updating as with
+programs, your own system can be quite stable. However, chances
+are that different machines have variants with better or worse
+rules, or maybe even with variants with features deleted.
+
+I'm sure that at some time Idris Samawi Hamid of the Oriental
+\TEX\ project (related to \LUATEX) will report on his experiences
+with font editors, feature editors, and typesetting engines in the
+process of making an Arabic font that performs the same way in all
+systems. Trial and error, rereading the specifications again and
+again, participating in discussions on forums, making special
+test fonts \unknown\ it's a pretty complex process. If you want to
+make a font that works okay in many applications you need to test
+your font with each of them, as the Latin Modern and \TEX\ Gyre
+font developers can tell you.
+
+This brings me to the main message of this chapter. On the one
+hand we're better of with \OPENTYPE\ fonts: installation is
+trivial, definitions are easy, and multi|-|lingual documents are
+no problem due to the fact that fonts are relatively complete.
+However, in traditional \TEX\ the user just used what came with
+the system and most decisions were already made by package
+writers. Now, with \OPENTYPE, users can choose features and this
+demands some knowledge about what they are, when they are supposed
+to be used (!), and what limitations they carry. In traditional
+\TEX\ the options were limited, but now there are many under user
+control. This demands some discipline. So, what we see is a shift
+from technology (installing, defining) to application (typography,
+quality). In \CONTEXT\ this has resulted in additional
+interfaces, like for instance dynamic feature switching, which
+decouples features from font definitions.
+
+It is already clear that \OPENTYPE\ fonts combined with \UNICODE\
+input will simplify \TEX\ usage considerably. Also, for macro
+writers things become easier, but they should be prepared to deal
+with the shortcomings on both \UNICODE\ and \OPENTYPE. For instance
+characters that belong together are not always organized
+logically in \UNICODE, which results for instance in math characters
+being (sort of) all over the place, which in turn means that in \TEX\
+characters can be either math or text, which in turn relates to the fonts
+being used, formatting etc. Als, macro package writers now need to take
+more languages and related interferences into account, but that's mostly
+a good thing, because it improves the quality of the output.
+
+It will be interesting to see how ten years from now \TEX\ macro
+packages deal with all the subtleties, exceptions, errors, and
+user demands. Maybe we will end up with as complex font support as
+for \TYPEONE\ with its many encodings. On the other hand, as with all
+technology, \OPENTYPE\ is not the last word on fonts.

+\chapter{Optimization}
+
+\subject{quality of code}
+
+How good is the \MKIV\ code? Well, as good as I can make it. When you browse
+the code you will probably notice differences in coding style and this is a
+related to the learning curve. For instance the \type {luat-inp} module needs
+some cleanup, for instance hiding local function from users.
+
+Since benchmarking has been done right from the start there is probably not
+that much to gain, but who knows. When coding in \LUA\ you should be careful
+with defining global variables, since they may override something. In \MKIV\
+we don't guarantee that the name you use for variable will not be used at
+some point. Therefore, best operate in a dedicated \LUA\ instance, or operate
+in userspace.
+
+\starttyping
+do
+    -- your code
+end
+\stoptyping
+
+If you want to use your data later on, think of working this way (the example
+is somewhat silly):
+
+\starttyping
+userdata['your.name'] = userdata['your.name'] or { }
+
+do
+    local mydata = userdata['your.name']
+
+    mydata.data = {}
+
+    local function foo() return 'bar' end
+
+    function mydata.dothis()
+        mydata[foo] = foo()
+    end
+
+
+end
+\stoptyping
+
+In this case you can always access your user data while temporary
+variables are hidden. The \type {userdata} table is predefined. As is
+\type {thirddata} for modules that you may write. Of course this
+assumes that you create a namespace within these global tables.
+
+A nice test for checking global cluttering is the following:
+
+\starttyping
+for k, v in pairs(_G) do
+    print(k, v)
+end
+\stoptyping
+
+When you incidentally define global variables like \type {n} or \type {str}
+they will show up here.
+
+\subject{clean or dirty}
+
+Processing the first 120 pages of this document (16 chapters) takes some 23.5
+seconds on a dell M90 (2.3GHZ, 4GB mem, Windows Vista Ultimate). A rough estimate
+of where \LUA\ spends its time is:
+
+\starttabulate[|l|c|]
+\NC \bf acticvity             \NC \bf sec \NC \NR
+\NC input load time           \NC 0.114   \NC \NR
+\NC fonts load time           \NC 6.692   \NC \NR
+\NC mps conversion time       \NC 0.004   \NC \NR
+\NC node processing time      \NC 0.832   \NC \NR
+\NC attribute processing time \NC 3.376   \NC \NR
+\stoptabulate
+
+Font loading takes some time, which is nu surprise because we load huge Zapfino, Arabic
+and \CJK\ fonts and define many instances of them. Some tracing learns that there
+are some 14.254.041 function calls, of which 13.339.226 concern functions that are
+called more than 5.000 times. A total of 62.434 function is counted, which is
+a result of locally defined ones.
+
+A rough indication of this overhead is given by the following test code:
+
+\starttyping
+local a,b,c,d,e,f = 1,2,3,4,5,6
+
+function one  (a)           local n = 1 end
+function three(a,b,c)       local n = 1 end
+function six  (a,b,c,d,e,f) local n = 1 end
+
+for i=1,14254041 do one  (a)           end
+for i=1,14254041 do three(a,b,c)       end
+for i=1,14254041 do six  (a,b,c,d,e,f) end
+\stoptyping
+
+The runtime for these tests (excluding startup) is:
+
+\starttabulate[|l|l|]
+\NC one argument    \NC 1.8 seconds \NC \NR
+\NC three arguments \NC 2.0 seconds \NC \NR
+\NC six arguments   \NC 2.3 seconds \NC \NR
+\stoptabulate
+
+So, the of the total runtime for this document we easily spend a couple
+of seconds on function calls, especially in node processing and attribute
+resolving. Does this mean that we need to change the code and follow a more
+inline approach? Eventually we may optimize some code, but for the moment
+we keep things as readable as possible, and even then much code is still
+quite complex. Font loading is often constant for a document anyway, and
+independent of the number of pages. Time spent on node processing depends on
+the script, and often processing intense scripts are typeset in a larger font and
+since they are less verbose than latin, this does not really influence
+the average time spent on typesetting a page. Attribute handling is probably
+the most time consuming activity, and for large documents the time spent on this
+is large compared to font loading and node processing. But then, after a few
+\MKIV\ development cycles the picture may be different.
+
+When we turned on tracing of function calls, if becomes clear where currently
+the time is spent in a document like this which demands complex Zapfino
+contextual analysis as well as Arabic analysis and feature application (both
+fonts demand node insertion and deletion). Of course using color also has a
+price. Handling weighted and conditional spacing (new in \MKIV) involves
+just over 10.000 calls to the main handler for 120 pages of this document.
+Glyph related processing of node lists needs 42.000 calls, and contextual
+analysis of \OPENTYPE\ fonts is good for 11.000 calls. Timing \LUA\ related
+tasks involves 2 times 37.000 calls to the stopwatch. Collapsing \UTF\ in
+the input lines equals the number of lines: 7700.
+
+However, at the the top of the charts we find calls to attribute related
+functions. 97.000 calls for handling special effects, overprint, transparency
+and alike, and another 24.000 calls for combined color and colorspace handling.
+These calls result in over 6.000 insertions of \PDF\ literals (this number is
+large because we show Arabic samples with color based tracing enabled). In
+case you wonder if the attribute handler can be made more efficient (we're
+talking seconds here), the answer is \quotation {possibly not}. This action
+is needed for each shipped out object and each shipped out page. If we divide
+the 24.000 (calls) by 120 (pages) we get 200 calls per page for color processing
+which is okay if you keep in mind that we need to recurse in nested horizontal
+and vertical lists of the completely made op page.
+
+\subject{serialization}
+
+When serializing tables, we can end up with very large tables, especially
+when dealing with big fonts like \quote{arabtype} or \quote {zapfino}. When
+serializing tables one has to find a compromise between speed of writing,
+effeciency of loading and readability. First we had (sub)tables like:
+
+\starttyping
+boundingbox = {
+    [1] = 0,
+    [2] = 0,
+    [3] = 100,
+    [4] = 200

+
+I mistakingly assumed that this would generate an indexed table, but at \TUG\ 2007
+Roberto Ierusalimschy explained to me that this was not that efficient, since this
+variant boils down to the following byte code:
+
+\starttyping
+1       [1]     NEWTABLE        0 0 4
+2       [2]     SETTABLE        0 -2 -3 ; 1 0
+3       [3]     SETTABLE        0 -4 -3 ; 2 0
+4       [4]     SETTABLE        0 -5 -6 ; 3 100
+5       [5]     SETTABLE        0 -7 -8 ; 4 200
+6       [6]     SETGLOBAL       0 -1    ; boundingbox
+7       [6]     RETURN          0 1
+\stoptyping
+
+This creates a hashed table. The following variant is better:
+
+\starttyping
+boundingbox = { 0, 0, 100, 200 }
+\stoptyping
+
+This results in:
+
+\starttyping
+1       [1]     NEWTABLE        0 4 0
+2       [2]     LOADK           1 -2    ; 0
+3       [3]     LOADK           2 -2    ; 0
+4       [4]     LOADK           3 -3    ; 100
+5       [6]     LOADK           4 -4    ; 200
+6       [6]     SETLIST         0 4 1   ; 1
+7       [6]     SETGLOBAL       0 -1    ; boundingbox
+8       [6]     RETURN          0 1
+\stoptyping
+
+The resulting tables are not only smaller in terms of bytes, but also
+are less memory hungry when loaded. For readability we write tables with
+only numbers, strings or boolean values in an inline||format:
+
+\starttyping
+boundingbox = { 0, 0, 100, 200 }
+\stoptyping
+
+The serialized tables are somewhat smaller, depending on how
+many subtables are indexed (boundary boxes, lookup sequences, etc.)

+\chapter{The order of things}
+
+Normally the text that makes up a paragraph comes directly from
+the input stream or macro expansions (think of labels). When \TEX\
+has collected enough content to make a paragraph, for instance
+because a \type {\par} token signals it \TEX\ will try to create
+one. The raw material available for making such a paragraph is
+linked in a list nodes: references to glyphs in a font, kerns
+(fixed spacing), glue (flexible spacing), penalties (consider them
+to be directives), whatsits (can be anything, e.g.\ \PDF\ literals
+or hyperlinks). The result is a list of horizontal boxes (wrappers with
+lists that represent \quote {lines}) and this is either wrapped in
+vertical box of added to the main vertical list that keeps the
+page stream.
+
+The treatment consists of four activities:
+
+\startitemize[packed]
+\item construction of ligatures (an f plus an i can become fi)
+\item hyphenation of words that cross a line boundary
+\item kerning of characters based on information in the font
+\item breaking the list in lines in the most optimal way
+\stopitemize
+
+The process of breaking into lines is also influenced by
+protrusion (like hanging punctuation) and expansion
+(hz-optimization) but here we will not take these processes
+into account. There are numerous variables that control
+the process and the quality.
+
+These activities are rather interwoven and optimized. For
+instance, in order to hyphenate, ligatures are to be decomposed
+and|/|or constructed. Hyphenation happens when needed. Decisions
+about optimal breakpoints in lines can be influenced by penalties
+(like: not to many hyphenated words in a row) and permitting extra
+stretch between words. Because a paragraph can be boxed and
+unboxed, decomposed and fed into the machinery again, information
+is kept around. Just imagine the following: you want to measure
+the width of a word and therefore you box it. In order to get the
+right dimensions, \TEX\ has to construct the ligatures and add
+kerns. However, when we unbox that word and feed it into the
+paragraph builder, potential hyphenation points have to be
+consulted and at such a point might lay between the characters
+that resulted in the ligature. You can imagine that adding (and
+removing) inter|-|character kerns complicates the process even
+more.
+
+At the cost of some extra runtime and memory usage, in \LUATEX\
+these steps are more isolated. There is a function that builts
+ligatures, one that kerns characters, and another one that
+hyphenates all words in a list, not just the ones that are
+candidate for breaking. The potential breakpoints (called
+discretionaries) can contain ligature information as well. The
+linebreak process is also a separate function.
+
+The order in which this happens now is:
+
+\startitemize[packed,intro]
+\item hyphenation of words
+\item building of ligatures from sequences of glyphs
+\item kerning of glyphs
+\item breaking all this into lines
+\stopitemize
+
+One can discuss endless about the terminology here: are we dealing
+with characters or with glyphs. When a glyph node is made, it
+contains a reference to a slot in a font. Because in traditional
+\TEX\ the number of slots is limited to 256 the relationship
+between characters in the input and the shape in the font, called
+glyph, is kind of indirect (the input encoding versus font
+encoding issue) while in \LUATEX\ we can keep the font in
+\UNICODE\ encoding if we want. In traditional \TEX, hyphenation is
+based on the font encoding and therefore glyphs, and although in
+\LUATEX\ this is still the case, there we can more safely talk of
+characters till we start mapping then to shapes that have no
+\UNICODE\ point. This is of course macro package dependent but in
+\CONTEXT\ \MKIV\ we normalize all input to \UNICODE\ exclusively.
+
+The last step is now really isolated and for that reason we can
+best talk in terms of preparation of the to-be paragraph when
+we refer to the first three activities. In \LUATEX\ these three
+are available as functions that operate on a node list. They each
+have their own callback so we can disable them by replacing the
+default functions by dummies. Then we can hook in a new function
+in the two places that matter: \type {hpack_filter} and \type
+{pre_linebreak_filter} and move the preparation to there.
+
+A simple overload is shown below. Because the first node is always
+a whatsit that holds directional information (and at some point in
+the future maybe even more paragraph related state info), we can
+safely assume that \type {head} does not change. Of course this
+situation might change when you start adding your own
+functionality.
+
+\starttyping
+local function my_preparation(head)
+    local tail = node.slide(head) -- also add prev pointers
+    tail = lang.hyphenate(head,tail)
+    tail = node.ligaturing(head,tail)
+    tail = node.kerning(head,tail)
+    return head
+end
+
+callback.register("pre_linebreak_filter", my_preparation)
+callback.register("hpack_filter",         my_preparation)
+
+local dummy = function(head,tail) return tail end
+
+callback.register("hyphenate",  dummy)
+callback.register("ligaturing", dummy)
+callback.register("kerning",    dummy)
+\stoptyping
+
+It might be clear that the order of actions matter. It might also
+be clear that you are responsible for that order yourself. There
+is no pre||cooked mechanism for guarding your actions and there are
+several reasons for this:
+
+\startitemize
+
+\item Each macro package does things its own way so any hard-coded
+mechanism would be replaced and overloaded anyway. Compare this to
+the usage of catcodes, font systems, auxiliary files, user
+interfaces, handling of inserts etc. The combination of callbacks,
+the three mentioned functions and the availability of \LUA\ makes
+it possible to implement any system you like.
+
+\item Macro packages might want to provide hooks for specialized
+node list processing, and since there are many places where code
+can be hooked in, some kind of oversight is needed (real people
+who keep track of interference of user supplied features, no
+program can do that).
+
+\item User functions can mess up the node list and successive
+actions then might make the wrong assumptions. In order to guard
+this, macro packages might add tracing options and again there are
+too many ways to communicate with users. Debugging and tracing has
+to be embedded in the bigger system in a natural way.
+
+\stopitemize
+
+In \CONTEXT\ \MKIV\ there are already a few places where users can
+hook code into the task list, but so far we haven't really
+encouraged that. The interfaces are simply not stable enough yet.
+On the other hand, there are already quite some node list
+manipulators at work. The most prominent one is the \OPENTYPE\
+feature handler. That one replaces the ligature and kerning
+functions (at least for some fonts). It also means that we need to
+keep an eye on possible interferences between \CONTEXT\ \MKIV\
+mechanisms and those provided by \LUATEX.
+
+For fonts, that is actually quite simple: the \LUATEX\ functions
+use ligature and kerning information stored in the \TFM\ table,
+and for \OPENTYPE\ fonts we simply don't provide that information
+when we define a font, so in that case \LUATEX\ will not ligature
+and kern. Users can influence this process to some extend by
+setting the \type {mode} for a specific instance of a font to
+\type {base} or \type {node}. Because \TYPEONE\ fonts have no
+features like \OPENTYPE\ such fonts are (at least currently)
+always are processed in base mode.
+
+Deep down in \CONTEXT\ we call a sequence of actions a \quote
+{task}. One such task is \quote {processors} and the actions
+discussed so far are in this category. Within this category we
+have subcategories:
+
+\starttabulate[|l|p|]
+\NC \bf subcategory \NC \bf intended usage \NC \NR
+\HL
+\NC before      \NC experimental (or module) plugins \NC \NR
+\NC normalizers \NC cleanup and preparation handlers \NC \NR
+\NC characters  \NC operations on individual characters \NC \NR
+\NC words       \NC operations on words \NC \NR
+\NC fonts       \NC font related manipulations \NC \NR
+\NC lists       \NC manipulations on the list as a whole \NC \NR
+\NC after       \NC experimental (or module) plugins \NC \NR
+\stoptabulate
+
+Here \quote {plugins} are experimental handlers or specialized
+ones provided in modules that are not part of the kernel. The categories
+are not that distinctive and only provide a convenient way to group
+actions.
+
+Examples of normalizers are: checking for missing characters and
+replacing character references by fallbacks. Character processors
+are for instance directional analysers (for right to left
+typesetting), case swapping, and specialized character triggered
+hyphenation (like compound words). Word processors deal with
+hyphenation (here we use the default function provided by \LUATEX)
+and spell checking. The font processors deal with \OPENTYPE\ as
+well as the ligature building and kerning of other font types.
+Finally, the list processors are responsible for tasks like special
+spacing (french punctuation) and kerning (additional
+inter||character kerning). Of course, this all is rather \CONTEXT\
+specific and we expect to add quite some more less trivial handlers
+the upcoming years.
+
+Many of these handlers are triggered by attributes. Nodes can have
+many attributes and each can have many values. Traditionally \TEX\
+had only a few attributes: language and font, where the first is
+not even a real attribute and the second is only bound to glyph
+nodes. In \LUATEX\ language is also a glyph property. The nice
+thing about attributes is that they can be set at the \TEX\ end
+and obey grouping. This makes them for instance perfect for
+implementing color mechanims. Because attributes are part of the
+nodes, and not nodes themselves, they don't influence or interfere
+processing unless one explicitly tests for them and acts
+accordingly.
+
+In addition to the mentioned task \quote {processors} we also have
+a task \quote {shipouts} and there will be more tasks in future
+versions of \CONTEXT. Again we have subcategories, currently:
+
+\starttabulate[|l|p|]
+\NC \bf subcategory \NC \bf intended usage \NC \NR
+\HL
+\NC before      \NC experimental (or module) plugins \NC \NR
+\NC normalizers \NC cleanup and preparation handlers \NC \NR
+\NC finishers   \NC manipulations on the list as a whole \NC \NR
+\NC after       \NC experimental (or module) plugins \NC \NR
+\stoptabulate
+
+An example of a normalizer is cleanup of the \quote {to be shipped
+out} list. Finishers deal with color, transparency, overprint,
+negated content (sometimes used in page imposition), special
+effects effect (like outline fonts) and viewer layers (something
+\PDF). Quite possible hyperlink support will also be handled there
+but not before the backend code is rewritten.
+
+The previous description is far from complete. For instance, not
+all handlers use the same interface: some work \type {head}
+onwards, some need a \type {tail} pointer too. Some report back
+success or failure. So the task handler needs to normalize their
+usage. Also, some effort goes into optimizing the task in such a
+way that processing the document is still reasonable fast. Keep in
+mind that each construction of a box invokes a callback, and there
+are many boxes used for constructing a page. Even a nilled
+callback is one, so for a simple one word paragraph four callbacks
+are triggered: the (nilled) hyphenate, ligature and kern callbacks
+as well as the one called \type {pre_linebreak_filter}. The task
+handler that we plug in the filter callbacks calls many functions
+and each of them does one of more passes over the node list, and
+in turn might do many call to functions. You can imagine that
+we're quite happy that \TEX\ as well as \LUA\ is so efficient.
+
+As I already mentioned, implementing a task handler as well as
+deciding what actions within tasks to perform in what order is
+specific for the way a macro package is set up. The following code
+can serve as a starting point
+
+\starttyping
+filters = { } -- global namespace
+
+local list = { }
+
+function filters.add(fnc,n)
+    if not n or n > #list + 1 then
+        table.insert(list,#list+1)
+    elseif n < 0 then
+        table.insert(list,1)
+    else
+        table.insert(list,n)
+    end
+end
+
+function filters.remove(fnc,n)
+    if n and n > 0 and n <= #list then
+        table.remove(list,n)
+    end
+end
+
+local function run_filters(head,...)
+    local tail = node.slide(head)
+    for _, fnc in ipairs(list) do
+        head, tail = fnc(head,tail,...)
+    end
+    return head
+end
+
+local function hyphenation(head,tail)
+    return head, tail, lang.hyphenate(head,tail) -- returns done
+end
+local function ligaturing(head,tail)
+    return node.ligaturing(head,tail) -- returns head,tail,done
+end
+local function kerning(head,tail)
+    return node.kerning(head,tail) -- returns head,tail,done
+end
+
+filters.add(hyphenation)
+filters.add(ligaturing)
+filters.add(kerning)
+
+callback.register("pre_linebreak_filter", run_filters)
+callback.register("hpack_filter",         run_filters)
+\stoptyping
+
+Although one can inject extra filters by using the \type {add}
+function it may be clear that this can be dangerous due to
+interference. Therefore a slightly more secure variant is the
+following, where \type {main} is reserved for macro package
+actions and the others can be used by add||ons.
+
+\starttyping
+filters = { } -- global namespace
+
+local list = {
+    pre = { }, main = { }, post = { },
+}
+
+local order = {
+    "pre", "main", "post"
+}
+
+local function somewhere(where)
+    if not where then
+        texio.write_nl("error: invalid filter category")
+    elseif not list[where] then
+        texio.write_nl(string.format("error: invalid filter category '%s'",where))
+    else
+        return list[where]
+    end
+    return false
+end
+
+function filters.add(where,fnc,n)
+    local list = somewhere(where)
+    if not list then
+        -- error
+    elseif not n or n > #list + 1 then
+        table.insert(list,#list+1)
+    elseif n < 0 then
+        table.insert(list,1)
+    else
+        table.insert(list,n)
+    end
+end
+
+function filters.remove(where,fnc,n)
+    local list = somewhere(where)
+    if list and n and n > 0 and n <= #list then
+        table.remove(list,n)
+    end
+end
+
+local function run_filters(head,...)
+    local tail = node.slide(head)
+    for _, lst in pairs(order) do
+        for _, fnc in ipairs(list[lst]) do
+            head, tail = fnc(head,tail,...)
+        end
+    end
+    return head
+end
+
+filters.add("main",hyphenation)
+filters.add("main",ligaturing)
+filters.add("main",kerning)
+
+callback.register("pre_linebreak_filter", run_filters)
+callback.register("hpack_filter",         run_filters)
+\stoptyping
+
+Of course, \CONTEXT\ users who try to use this code will
+be punished by loosing much of the functionality already
+present, simply because we use yet another variant of the
+above code.

+\chapter{How about performance}
+
+\subject{remark}
+
+The previous chapters already spent some words on performance
+and memory usage. By the time that Taco and I were implementing,
+discussing and testing the callbacks related to node lists, we were
+already convinced that in all areas covered so far (file management,
+handling input characters, dealing with fonts, conversion to tokens,
+string and table manipulation, enz.) the \TEX||\LUA\ pair was up to
+the task  And so we were quite confident that processing nodes was
+not only an important aspect of \LUATEX\ but also quite feasable
+in terms of performance (after all we needed it in order to deal
+with advanced typesetting of Arab). When Taco was dealing with the
+\TEX\ side of the story, I was experimenting with possible
+mechanisms at the \LUA\ end.
+
+At the same time I got the opportunity to speed up the \METAPOST\
+to \PDF\ converter and both activities involved some timing. Here
+I report some of the observations that we made in this process.
+
+\subject{parsing}
+
+Expressions in \LUA\ are powerful and definitely faster than regular
+expressions found in other languages, but they have some limits. Most
+noticeably is the lack of alternation. In \RUBY\ one can say:
+
+\starttyping
+str = "there is no gamma in here, just an beta"
+
+if str =~ /(alph|bet|delt)a/ then
+    print($1)
+end
+\stoptyping
+
+but in \LUA\ you need a few more lines:
+
+\starttyping
+str = "there is no gamma in here, just an beta"
+
+for _, v in pairs({'alpha','beta','delta'}) do
+    local s = str:match(v)
+    if s then
+        print(s)
+        break
+    end
+end
+\stoptyping
+
+Interesting is that upto now I didn't really miss alternation but
+it may as well be that the lack of it drove me to come up with
+different solutions. For \CONTEXT\ \MKIV\ the \METAPOST\ to \PDF\
+converter has been rewritten in \LUA. This is a prelude to direct
+\LUA\ output from \METAPOST\ but I needed the exercise. It was
+among the first \LUA\ code in \MKIV.
+
+Progressive (sequential) parsing of the data is an option, and is
+done in \MKII\ using pure \TEX. We collect words and compare them
+to \POSTSCRIPT\ directives and act accordingly. The messy parts
+are scanning the preamble, which has specials to be dealt with as
+well as lots of unpredictable code to skip, and the \type
+{fshow} command which adds text to a graphic. But real dirty are
+the code fragments that deal with setting the line width and
+penshapes so the cleanup of this takes some time.
+
+In \LUA\ a different approach is taken. There is an \type {mp} table
+which collects a lot of functions that more or less reflect the
+output of \METAPOST. The functions take care of generating the right
+\PDF\ code and also handle the transformations needed because of
+the differences between \POSTSCRIPT\ and \PDF.
+
+The sequential \POSTSCRIPT\ that comes from \METAPOST\ is
+collected in one string and converted using \type {gsub} into a
+sequence of \LUA\ function calls. Before this can be done, some
+cleanup takes place. The resulting string is then executed as
+\LUA\ code.
+
+As an example:
+
+\starttyping
+1 0 0 2 0 0 curveto
+\stoptyping
+
+becomes
+
+\starttyping
+mp.curveto(1,0,0,2,0,0)
+\stoptyping
+
+which results in:

+\stoptyping
+
+In between, the path is stored and transformed which is needed in
+the case of penshapes, where some \POSTSCRIPT\ feature is used that
+is not available in \PDF.
+
+During the development of \LUATEX\ a new feature was added to
+\LUA: \type {lpeg}. With \type {lpeg} you can define text scanners. In
+fact, you can build parsers for languages quite conveniently so
+without doubt we will see it show up all over \MKIV.
+
+Since I needed an exercise to get accustomed with \type {lpeg}, I
+rewrote the mentioned converter. I'm sure that a better implementation
+is possible than I did (after all, \POSTSCRIPT\ is a language) but
+I went for a speedy solution. The following table shows some timings.
+
+\starttabulate[|c|c|l|]
+\HL
+\NC \tt gsub \NC \tt lpeg \NC \NC \NR
+\HL
+\NC  2.5     \NC 0.5      \NC 100 times test graphic \NC \NR
+\NC  9.2     \NC 1.9      \NC 100 times big graphic  \NC \NR
+\HL
+\stoptabulate
+
+The test graphic has about everything that \METAPOST\ can output,
+including special tricks that deal with transparency and shading. The
+big one is just four copies of the test graphic.
+
+So, the \type {lpeg} based variant is about 5~times faster than the
+original variant. I'm not saying that the original implementation is
+that brilliant, but a 5~time improvement is rather nice especially
+when you consider that \type {lpeg} is still experimental and each
+version performs better. The tests were done with \type {lpeg}
+version 0.5 which performs slightly faster than its predecessor.
+
+It's worth mentioning that the original \type {gsub} based variant
+was already a bit improved compared to its first implementation.
+There we collected the \TEX\ (\PDF) code in a table and passed it
+in its concatenated form to \TEX. Because the \LUA\ to \TEX\
+interface is by now quite efficient we can just pass the
+intermediate results directly to \TEX.
+
+\subject{file io}
+
+The repertore of functions that deal with individual characters
+in \LUA\ is small. This does not bother us too much because the
+individual character is not what \TEX\ is mostly dealing with. A
+character or sequence of characters becomes a token (internally
+represented by a table) and tokens result in nodes (again
+tables, but larger). There are many more tokens involved than
+nodes: in \CONTEXT\ a ratio of 200~tokens on 1~node are not
+uncommon. A letter like \type {x} become a token, but the control
+sequence \type {\command} also ends up as one token. Later on,
+this \type {x} may become a character node, possibly surrounded
+by some kerning. The input characters \type {width} result in
+5~tokens, but may not end up as nodes at all, for instance when
+they are part of a key|/|value pair in the argument to a command.
+
+Just as there is no guaranteed one||to||one relationship between
+input characters and tokens, there is no straight relation between
+tokens and nodes. When dealing with input it is good to keep in mind
+that because of these interpretation stages one can never say that
+1~megabyte of input characters ends up as 1~million something in
+memory. Just think of how many megabytes of macros get stored in a
+format file much smaller than the sum of bytes.
+
+We only deal with characters or sequences of bytes when reading
+from an input medium. There are many ways to deal with the input.
+For instance one can process the input lines as \TEX\ sees them,
+in which case \TEX\ takes care of the \UTF\ input. When we're
+dealing with other input encodings we can hook code into the file
+openers and readers and convert the raw data ourselves. We can for
+instance read in a file as a whole, convert it using the normal
+expression handlers or the byte(pair) iterators that \LUATEX\
+provides, or we can go real low level using native \LUA\ code,
+as in:
+
+\starttyping
+do
+    local function nextbyte(f)
+        return f:read(1)
+    end
+
+    function io.bytes(f)
+        return nextbyte, f
+    end
+end
+
+f = io.open("somefile.dat")
+for b in io.bytes(f) do
+    do_something(b)
+end
+f:close()
+\stoptyping
+
+Of course in practice one will need to integrate this into one of the
+reader callback, but the principle stays the same. In case you wonder
+if calling functions for each byte is fast enough \unknown\ it's more than
+fast enough for normal purposes, especially if we keep in mind that other
+tasks like reading of, preparing of and dealing with fonts of processing
+token lists take way more time. You can be sore that when half a second
+runtime is spent on reading a file, processing may take minutes. If one
+wants to sqeeze more performance out of this part, it's always an option
+to write special libraries for that, but this is beyond standard \LUATEX.
+We found out that the speed of loading data from files in \LUA\ is
+mostly related to the small size of \LUA's file buffer. Reading data stored
+in tables is extremely fast, and even faster when precompiled into bytecode.
+
+\subject{tables}
+
+When Taco and I were experimenting with the callbacks that intercept
+tokens and nodes, we wondered what the impact would be on performance.
+Although in \MKIV\ we allocate quite some memory due to font handling,
+we were pretty sure that handling \TEX's internal lists also could
+have their impact. Data related to fonts is not always subjected to
+garbage collection, simply because it's to be available permanently.
+List processing on the other hand involves a lot of temporary allocated
+tables. During a run a real huge amount of tokens passes the machinery.
+When digested, they become nodes. For testing we normally use this
+document (with the name \type {mk.tex}) and at the time of writing
+this, it has some 48 pages.
+
+This document is of moderately complexity, but not as complex as
+the documents that I normally process; they have with lots of graphics,
+layers, structural elements, maybe a bit of \XML\ parsing, etc.
+Nevertheless, we're talking of some 24~million tokens entering the engine
+for 50 pages of text. Contrary to this the number of nodes is small:
+only 120~thousand but the tables making up the nodes are more complex than
+token tables (with three numbers per token). When all tokens are intercepted
+and returned unchanged, on my machine the run is progressively slow and
+memory usage grows from 75M to 112M. There is room for improvement there,
+especially in the garbage collector.
+
+Side note: quite some of these tokens result from macro expansion. Also,
+when in the input a \type {\command} is used, the callback passes it as one
+token. A command stores in a format is already tokenized, but a command read
+from the input is tokenized when read, so behind each token reported there
+can be a few more input characters, but their number can be neglected compared
+to tokens originating from the macro package.
+
+The token callback is rather slow when used for a whole document. However,
+this is typically a callback that will only be used in very special
+situations and for a controlled number of tokens. The node callback on the
+other hand can be set permanently. Fortunately the number of nodes is
+relatively small. The overhead of a simple token handler that just counts
+nodes is around 5\% but most common manipulations with token lists don't
+take much more time. For instance, experiments with adding kerns around
+punctuation (a French speciality) hardly takes time, resolving ligatures is
+not really noticeable and applying inter||character spacing to a whole document
+is not that slow either. Actually, the last example is kind of special
+because it more than doubles the size of the node lists. Inserting or removing
+table elements in relatively slow when tables are large but there are some
+ways around this.
+
+One of the reasons of whole||document token handling being slow is that
+each token is a three||element table and so the garbage collector has to work
+rather hard. The efficiency of this process is also platform dependent (or
+maybe compiler specific). Manipulating the garbage collector parameters
+does not improve performance, unless this forces the collector to be inefficient
+at the cost of a lot of memory.
+
+However, when we started dealing with nodes, I gave tuning the collector
+another try and on the mentioned test document the following observations
+were made when manipulating the step multiplier:
+
+\starttabulate[|c|c|c|]
+\HL
+\NC \bf step \NC \bf runtime \NC \bf memory \NC \NR
+\HL
+\NC 200 \NC 24.0 \NC 80.5M \NC \NR
+\NC 175 \NC 21.0 \NC 78.2M \NC \NR
+\NC 150 \NC 22.0 \NC 74.6M \NC \NR
+\NC 160 \NC 22.0 \NC 74.6M \NC \NR
+\NC 165 \NC 21.0 \NC 77.6M \NC \NR
+\NC 125 \NC 21.5 \NC 89.2M \NC \NR
+\NC 100 \NC 21.5 \NC 88.4M \NC \NR
+\HL
+\stoptabulate
+
+As a result, I decided to set the \type {stepmul} variable to~165.
+
+\starttyping
+\ctxlua{collectgarbage("setstepmul", 165)}
+\stoptyping
+
+However,  when we were testing thenew \type {lpeg} based \METAPOST\ converter, we ran
+into problems. For table intensive operations, temporary disabling the
+garbage collector gave a significant boost in speed. While testing
+performance we used the following loop:
+
+\starttyping
+\dorecurse {2000} {
+    \setbox \scratchbox \hbox \bgroup
+        \convertMPtoPDF{test-mps-procset.mps}{1}{1}
+    \egroup
+}
+\stoptyping
+
+In such a loop, turning the garbage collector on and off is disasterous. Because
+no other \LUA\ calls happen between these calls, the garbage collector is never
+invoked at all. As a result, memory growed from the baseline of 45M to 120MB and
+processing became incrementally slow. I found out that restarting the collector
+before each conversion kept memory usage low and the speed also remained okay.
+
+\starttyping
+\ctxlua{collectgarbage("restart")}
+\stoptyping
+
+Further experiments learned that it makes sense to restart the collector at
+each shipout and before table intense operations. On \type {mk.tex} this
+results in a memory usage of 74M (at the end of the run) and a runtime of
+21~seconds.
+
+Concerning nodes and speed|/|allocation issues, we need to be aware of
+the fact that this was still somewhat experimental and in the final version
+of \LUATEX\ callbacks may occur at different places and lists may be subjected
+to parsing multiple times at different moments and locations (for instance when
+we start dealing with attributes, an upcoming new feature).
+
+Back to tokens. The reason why applying the callback to every token takes a
+while has to do with the fact that each token goes through the associated
+function. If you want to have an idea of what this means for 24~million
+tokens, just run the following \LUA\ code:
+
+\starttyping
+for i=1,24 do
+    print(i)
+    for j=1,1000*1000 do
+        local t = { 1, 2, 3 }
+    end
+end
+print(os.clock())
+\stoptyping
+
+This takes some 60 seconds on my machine. The following code
+runs about three times faster because the table has not to
+be allocated each time.
+
+\starttyping
+t = { 1, 2, 3 }
+for i=1,24 do
+    print(i)
+    for j=1,1000*1000 do
+        t[1]=4 t[2]=5 t[3]=6
+    end
+end
+print(os.clock())
+\stoptyping
+
+Imagine this code to be interwoven with other code and \TEX\ doing
+things with the tokens it gets back. The memory pool will be
+scattered and garbage collecting will become more difficult.
+
+However, in practice one will only apply token handling
+to a marked piece of the input data. It is for this reason
+that the callback is not:
+
+\starttyping
+callback.register('token_filter', function(t)
+    return t
+end )
+\stoptyping
+
+but instead
+
+\starttyping
+callback.register('token_filter', function()
+    return token.get_next()
+end )
+\stoptyping
+
+This gives the opportunity to fetch more than one token and
+keep fetching till a criterium is met (for instance a sentinel).
+
+Because \type {token.get_next} is not bound to the callback you
+can fetch tokens anytime you want and only use the callback to
+feed back tokens into \TEX. In \CONTEXT\ \MKIV\ there is some
+collect and flush tokens present. Here is a trivial example:
+
+\starttyping
+\def\SwapChars{\directlua 0 {
+    do
+        local t = { token.get_next(), token.get_next() }
+        callback.register('token_filter', function()
+            callback.register('token_filter', nil)
+            return { t[2], t[1] }
+        end )
+    end
+}}
+
+\SwapChars HH \SwapChars TH
+\stoptyping
+
+Collecting tokens can take place inside the callback but also
+outside. This also gives you the opportunity to collect them
+in efficient ways and keep an eye on the memory demands.
+
+Of course using \TEX\ directly takes less code:
+
+\starttyping
+\def\SwapChars#1#2{#2#1}
+\stoptyping
+
+The example shown here involves so little tokens that running
+it takes no noticeable time. Here we show this definition in
+tokenized form:
+
+\starttokens[demo]\def\SwapChars#1#2{#2#1}\stoptokens \setups{ShowCollect}

+\chapter {Just plain}
+
+\subject{running}
+
+For testing basic \LUATEX\ functionality it makes sense to have a
+minimal system, and traditionally plain \TEX\ has been the most
+natural candidate. It is for this reason that it had been on the
+agenda for a while to provide basic \OPENTYPE\ font support for
+plain \TEX\ as well. Although the \MKIV\ node mode subsystem is
+not yet perfect, the time was right to start experimenting with a
+subset of the \MKIV\ code.
+
+Using plain roughly comes down to the following. First you need
+to generate a format:
+
+\starttyping
+luatex --ini --fmt=luatex.fmt luatex-plain.tex
+\stoptyping
+
+This format has to be moved to a place where it can be found by
+the \KPSE\ library. Since this can differ per distribution there
+is no clear recipe for it, but for \TEXLIVE\ some path ending in
+\type {web2c/luatex} is probably the right spot. After that you
+can run
+
+\starttyping
+luatex luatex-test.tex
+\stoptyping
+
+This file lives under \type {generic/context}. When it
+is run it is quite likely that you will get an error message
+because the font name database cannot be found. You
+can generate one with the following command (which assumes that
+you have \CONTEXT\ installed):
+
+\starttyping
+mtxrun --usekpse --script fonts --names
+\stoptyping
+
+The resulting file \type {luatex-fonts-names.lua} has to be placed
+somewhere in your \TEX\ tree so that it can be found anytime.
+Beware: the \type {--usekpse} flag is only used outside \CONTEXT\
+and provides very limited functionality, just enough for this
+task. Again this is a distribution specific issue so we will not
+dwell upon it here.
+
+The way fonts are defined is modelled after \XETEX, as it makes no
+sense to support the somewhat more fancy \CONTEXT\ way of doing
+things. Keep in mind that although \CONTEXT\ \MKIV\ does support
+the \XETEX\ syntax too, the preferred way there is to use a more
+symbolic feature definition approach.
+
+As this is an experimental setup, it might not always work out as
+expected. Around \LUATEX\ version 0.50 we expect the code to be
+more or less okay.
+
+\subject{implementation}
+
+The \type {luatex-fonts.lua} file is the first in a series of
+basic functionality enhancements for \LUATEX\ derived from the
+\CONTEXT\ \MKIV\ code base. Please don't pollute the \type
+{luatex-*} namespace with code not coming from the \CONTEXT\
+development team as we may add more files.
+
+This file implements a basic font system for a bare \LUATEX\
+system. By default \LUATEX\ only knows about the classic \TFM\
+fonts but it can read other font formats and pass them to \LUA.
+With some glue code one can then construct a suitable \TFM\
+representation that \LUATEX\ can work with. For more advanced font
+support a bit more code is needed that needs to be hooked
+into the callback mechanism.
+
+This file is currently rather simple: it just loads the \LUA\ file
+with the same name. An example of a \type {luatex.tex} file that is
+just the plain \TEX\ format:
+
+\starttyping
+\catcode`\{=1 % left brace is begin-group character
+\catcode`\}=2 % right brace is end-group character
+
+\input plain
+
+\everyjob\expandafter{\the\everyjob\input luatex-fonts\relax}
+
+\dump
+\stoptyping
+
+We could load the \LUA\ file in \type {\everyjob} but maybe some
+day we will need more here.
+
+When defining a font, in addition to the \XETEX\ way, you can use
+two prefixes. A \type {file:}\ prefix forces a file search, while
+a \type {name:}\ prefix will result in consulting the names
+database. The font definitions shown in figure~1 are all valid.
+

+\stoptyping
+
+You can load maths fonts but as Plain \TEX\ is set up for Computer
+Modern (and as we don't adapt Plain \TEX) loading Cambria does
+not give you support for its math features automatically.
+
+If you want access by name you need to generate a font
+database, using:
+
+\starttyping
+mtxrun --script font --names
+\stoptyping
+
+and put the resulting file in a spot where \LUATEX\ can find it.
+
+\subject {remarks}
+
+The code loaded in \type {luatex-fonts.lua} does not come out of
+thin air, but is mostly shared with \CONTEXT; however, in that
+macro package we go beyond what is provided in the plain variant.
+When using this code you need to keep a few things in mind:
+
+\startitemize
+
+\item This subsystem will be extended, improved etc.\ at about the
+same pace as \CONTEXT\ \MKIV. However, because \CONTEXT\ provides a
+rather high level of integration not all features will be supported
+in the same quality. Use \CONTEXT\ if you want more goodies.
+
+\item There is no official \API\ yet, which means that using
+functions implemented here is at your own risk, in the sense that
+names and namespaces might change. There will be a minimal \API\
+defined once \LUATEX\ version 1.0 is out. Instead of patching the
+files it's better to overload functions if needed.
+
+\item The modules are not stripped too much, which makes it
+possible to benefit from improvements in the code that take place
+in the perspective of \CONTEXT\ development. They might be split a
+bit more in due time so the baseline might become smaller.
+
+\item The code is maintained and tested by the \CONTEXT\
+development team. As such it might be better suited for this macro
+package and integration in other systems might demand some
+additional wrapping. The plain version discussed here is the
+benchmark and should be treated as a kind of black box.
+
+\item Problems can be reported to the team but as we use \CONTEXT\
+\MKIV\ as our baseline, you'd better check if the problem is a general
+\CONTEXT\ problem too.
+
+\item The more high level support for features that is provided in
+\CONTEXT\ is not part of the code loaded here as it makes no sense
+elsewhere. Some experimental features are not part of this code
+either but some might show up later.
+
+\item Math font support will be added but only in its basic form
+once the Latin Modern and \TEX\ Gyre math fonts are
+available. Currently traditional and \OPENTYPE\ math fonts can
+be loaded.
+
+\item At this moment the more nifty speedups are not enabled
+because they work in tandem with the alternative file handling
+that \CONTEXT\ uses. Maybe around \LUATEX\ 1.0 we will bring some
+speedup into this code too (if it pays off at all).
+
+\item The code defines a few global tables. If this code is used
+in a larger perspective then you can best make sure that no
+conflicts occur. The \CONTEXT\ package expects users to work in
+their own namespace (\type {userdata}, \type {thirddata}, \type
+{moduledata} or \type {document}). We give ourselves the freedom to
+use any table at the global level but will not use tables that are
+named after macro packages. Later, \CONTEXT\ might operate in
+a more controlled namespace but it has a low priority.
+
+\item There is some tracing code present but this is not enabled
+and not supported as it integrates quite tightly into \CONTEXT. In
+case of problems you can use \CONTEXT\ for tracking down problems.
+
+\item Patching the original code in distributions is dangerous as
+it might fix your problem but introduce new ones for \CONTEXT. So,
+best keep the original code as it is and overload functions and
+callbacks when needed. This is trivial in \LUA.
+
+\item Attributes are (automatically) taken from the range 127||255 so
+you'd best not use these yourself. Don't count on an attribute number
+staying the same and don't mess with these attributes.
+
+\stopitemize
+
+If this all sounds a bit strict, keep in mind that it makes no sense
+for us to maintain multiple code bases and we happen to use \CONTEXT.
+
+\subject{advanced features}
+
+The latest versions now also support font extending, slanting,
+protrusion and expansion. Here are a few examples:
+
+\starttyping
+\pdfprotrudechars2 \pdfadjustspacing2
+
+\font\testa=file:lmroman12-regular:+liga;extend=1.5         at 12pt
+\font\testb=file:lmroman12-regular:+liga;slant=0.8          at 12pt
+\font\testc=file:lmroman12-regular:+liga;protrusion=default at 12pt
+\font\testd=file:lmroman12-regular:+liga;expansion=default  at 12pt
+\stoptyping
+
+The extend and slant options are similar to those used in
+map files. The extend is limited to 10 and the slant to 1.
+
+In the protrusion and expansion specification the keyword \type
+{default} is an entry in a definition table. You can find an
+example at the end of \type {font-dum.lua}.
+
+A setup for expansion looks as follows:
+
+\starttyping
+fonts.expansions.setups['default'] = {
+    stretch = 2, shrink = 2, step = .5, factor = 1,
+
+    [byte('A')] = 0.5, [byte('B')] = 0.7,
+    ...........
+    [byte('8')] = 0.7, [byte('9')] = 0.7,
+}
+\stoptyping
+
+The stretch, shrink and steps become font properties
+and characters gets a value assigned. In pseudo code
+it looks like:
+
+\starttyping
+chr(A).expansion_factor = 0.5 * factor
+\stoptyping
+
+The protrusion table has left and right protrusion
+factors for each relevant character.
+
+\starttyping
+fonts.protrusions.setups['default'] = {
+    factor = 1, left = 1, right = 1,
+
+    [0x002C] = { 0, 1 }, -- comma
+    [0x002E] = { 0, 1 }, -- period
+    [0x003A] = { 0, 1 }, -- colon
+    ........
+    [0x061B] = { 0, 1 }, -- arabic semicolon
+    [0x06D4] = { 0, 1 }, -- arabic full stop
+}
+\stoptyping
+
+So, the comma will stick out in the right margin:
+
+\starttyping
+chr(comma).right_protruding = right * 1 * factor
+\stoptyping
+
+As we prefer measures relative to the width (precentages) we
+actualy use:
+
+\starttyping
+chr(comma).right_protruding = right * 1 * factor * (width/quad)
+\stoptyping
+
+You can add additional tables and access them by keyword in the
+font specification.
+
+The model used in the plain variant is a simplification of the
+\CONTEXT\ model so \CONTEXT\ users should not take this as
+starting point.

+\chapter{How to convince Don and Hermann to use \LUATEX}
+
+{\em The code shown here should look a bit different in versions
+of \MKIV\ after March 2011. This is because the font system was
+cleaned up and upgraded. The prinicples remain the same. You can
+have a look at \type {m-punk.mkiv} in the \CONTEXT\ distribution.}
+
+Odds are pretty low that Don Knuth will use \LUATEX\ for
+typesetting the next update of his opus magnum, and odds are even
+lower that Hermann Zapf will use \MPLIB\ for Melior Nova. However,
+the next example of combining \METAFONT\ and \TEX\ may draw their
+interest in this new variant: \METATEX.
+
+The font used here is called \quote {punk} and is designed by
+Donald Knuth. There is a note in the file that says: \quotation
+{Font inspired by Gerard and Marjan Unger's lectures, February
+1985}. If you didn't notice it yet: punk is a random font.
+
+You may wonder why we started looking into this masterpiece of
+font design. Well, there are a few reasons:
+
+\startitemize
+
+\item  We always liked this font, but after the rise of outline
+       fonts it was not a natural candidate for using in
+       documents. Fun is always a good motive.
+
+\item  For many years we have been suggesting that special glyphs
+       and/or aspects of typesetting could be realized by runtime
+       generation of graphics, and we need this testbed for the
+       Oriental \TEX\ project: Idris needs stretchable inter|-|glyph
+       connections.
+
+\item  Taco likes using tricky \METAPOST\ backgrounds for his
+       presentations that demonstrate this programming language.
+
+\item  Hartmut loves to tweak the backend and runtime font generation
+       will demand some extensions to the font inclusion and literal
+       handlers.
+
+\item  Because Hans attends many \TEX\ conferences together with Volker
+       Schaa, he has promised him to avoid repeating talk and
+       presentation layouts, and so a new presentation style was needed.
+
+\stopitemize
+
+To this we can add an already mentioned motivation: convince Don and
+Hermann to use \LUATEX\ \unknown\ who knows. And, if that fails, maybe
+they can team up for an extensions to this font: more style variants,
+proper math and the full range of \UNICODE\ glyphs.
+
+The punk font is written in \METAFONT\ and there are multiple
+sources. These are merged into one file which is to be processed
+using the \type {mfplain} format. Definitions of characters in
+this font look like:
+
+\starttyping
+beginpunkchar ("A",13,1,2) ;
+    z1 = pp(1.5u,0) ; z2 = (.5w,1.1h) ; z3 = pp(w-1.5u,0) ;
+    pd z1 ; pd z3 ; draw z1 -- z2 -- z3 ;
+    z4 = pp .3[z1,z2] ; z5 = pp .3[z3,z2] ;
+    pd z4 ; pd z5 ; draw z4 -- z5;
+endchar ;
+\stoptyping
+
+When \TEX\ needs a font, i.e.\ when we have something like this:
+
+\starttyping
+\font\somefont=whatever at 12pt
+\stoptyping
+
+in \CONTEXT\ control is delegated to a font loader written in
+\LUA\ that is hooked into \TEX. This loader interprets the name
+and if needed filters the specification from it. Think of this:
+
+\starttyping
+\font\somefont=whatever*smallcaps at 16pt
+\stoptyping
+
+This means: load font \type {whatever} and enable the smallcaps features.
+However this mechanism is mostly geared towards \TYPEONE\ and \OPENTYPE\
+fonts. But punk is neither: it's a \METAFONT, and we need to treat it as
+such. We will use \LUATEX's powerful virtual font technology
+because that way we can smuggle the proper shapes in the final
+file. And \unknown\ no bitmaps and no funny encoding.
+
+In \CONTEXT\ \MKIV\ there is a preliminary virtual font definition
+mechanism. There is no advanced \TEX\ interface yet so we need to do it in
+\LUA. Fortunately we do have access to this from the font mechanism:
+
+\starttyping
+\font\somefont=mypunk@punk at 20pt
+\stoptyping
+
+This is a rather valid directive to create a font that internally
+will be called \type {mypunk}. For this the virtual font creation
+command \type {punk} will be used, and in a moment we will see what
+this triggers.
+
+Of course, users will never see such low level definitions. They will
+use proper typescript, which set up a whole font system. For instance,
+in this document we use:
+
+\typebuffer[fontdefinition]
+
+Now, using punk in inself is not that much of a challenge, but how about
+using multiple instances of this font and then typeset the text chosing
+variants of a glyph at random. Of course this will have some trade-off in
+terms of runtime. In this document we use punk as the bodyfont and
+therefore it comes in several sizes. On Hans's laptop generating the
+glyphs takes a while:
+
+\starttyping
+7500 glyphs, 12.887 seconds runtime, 581 glyphs/second
+\stoptyping
+
+Fortunately \MKIV\ provides a caching mechanism so once the fonts
+are generated, a next run will be more comfortable. This time we
+get reported:
+
+\starttyping
+0.187 seconds, 60 instances, 320.856 instances/second
+\stoptyping
+
+which is not that bad for loading 60 files of 5 megabytes \PDF\
+literals each. The reason why the files are large is that although
+these glyphs look simple, in fact they are rather complex: each
+glyph at least one paths and several knots, and since a special
+pen is used, conversion results in a larger than normal description
+of a shape.
+
+Since we use the standard converter from \METAPOST\ to \PDF, we
+can gain some generation time by using a dedicated converter for
+glyphs. Eventually the \MPLIB\ library may even provide a proper
+charstring generator so that we can construct real fonts at
+runtime.
+
+So, how does this work behind the screens? Because we can use some
+of the mechanisms already present in \CONTEXT\ it is not even that complex.
+
+\startitemize
+
+\item The \type {punk} directive tells \CONTEXT\ to create a virtual
+      font. Such a font can be made out of real fonts; we use this
+      for instance in the font feature \type {combine}, where we
+      add virtually composed characters that are missing by combining
+      characters present. However, here we have no real font.
+
+\item And so this virtual font is not build on top of an existing font, but
+      spawns a \MPLIB\ process that will build the font, unless it is
+      present in the cache on disk. The shapes are converted to \PDF\ literals
+      and for each character a proper definition table is made.
+
+\item In total 10 such fonts are made, but only one is returned to the
+      font callback that asked us to provide the font. The list of
+      the alternatives is stored in the \LUA\ table that represents
+      the font and kept at the \LUA\ end. So, for each size used,
+      a unique set of 10 variants is generated.
+
+\item The randomizer operates on the node list. Instead of using a
+      dedicated mechanism for this, we hijack one of the attribute values
+      of the case swapper already present in \MKIV. After that we can selectively
+      turn on and off the randomizer.
+
+\item At some point \TEX\ will hand over the node lists to \CONTEXT. At
+      that moment a lot of things can happen to the list, and one of
+      them is a sequence of character handlers, of which the mentioned case
+      handler is one. The handler sweeps over the nodelist
+      and for each glyph node triggers a function that is bound to the
+      attribute value.
+
+\item This function is rather trivial: it looks at the font id of the
+      glyph, and resolves it to the font table. If that table has a
+      list of alternatives, it will randomly choose one and assign it to
+      the font attribute of the glyph. That's all.
+
+\item Eventually the backend routines will inject the \PDF\ literals that
+      were collected in the commands table of the virtual glyph.
+
+\stopitemize
+
+It will not come as a surprise that our resulting file is larger
+than what we get when using traditional outline fonts or just one
+instance of punk. However, this is just an experiment, and
+eventually a proper font constructor will be provided, so that the
+glyph drawing is delegated to the font renderer. An intermediate
+optimization can be to use so called \PDF\ xforms, but a properly
+runtime generated font is best because then we can search in the
+file too.
+
+Because by now reading the punk font should go fluently we can now
+move on to the code. We already have a \type {fonts} namespace,
+which we now extend with an \METAPOST\ sub namespace:
+
+\starttyping
+fonts.mp = fonts.mp or { }
+\stoptyping
+
+We set a version number and define a cache on disk. When the number changes
+fonts stored in the cache will be regenerated when needed. The
+\type {containers} module provides the relevant function.
+
+\starttyping
+fonts.mp.version = 1.01
+fonts.mp.cache = containers.define("fonts", "mp", fonts.mp.version, true)
+\stoptyping
+
+We already have a \type {metapost} namespace, and within it we define a
+sub namespace:
+
+\starttyping
+metapost.characters = metapost.characters or { }
+\stoptyping
+
+Now we're ready for the real action: we define a dedicated flusher
+that will be passed to the \METAPOST\ converter. A next version of
+\MPLIB\ will provide the \TFM\ font information which gives better
+glyph dimensions, plus additional kerning information. All this code
+is defined in a closure (\type {do ... end}) which
+nicely hides the local variables.
+
+\starttyping
+local characters, descriptions = { }, { }
+local factor, total, variants = 100, 0, 0
+local l, n, w, h, d  = { }, 0, 0, 0, 0
+
+local flusher = {
+    startfigure = function(chrnum,llx,lly,urx,ury)
+        l, n = { }, chrnum
+        w, h, d = urx - llx, ury, -lly
+        total = total + 1
+    end,
+    flushfigure = function(t)
+        for i=1, #t do
+            l[#l+1] = t[i]
+        end
+    end,
+    stopfigure = function()
+        local cd = characters.data[n]
+        descriptions[n] = {
+            unicode = n,
+            name = cd and cd.adobename,
+            width = w*100,
+            height = h*100,
+            depth = d*100,
+        }
+        characters[i] = {
+            commands = {
+                { "special", "pdf: " .. table.concat(l," ") },
+            }
+        }
+    end
+}
+\stoptyping
+
+In the normal converter, the start and stop function do the
+packaging in a box. The flush function is called when literals
+need to be flushed. This threesome does as much as collecting
+glyph information in the \type {list} table. Intermediate literals
+are stored in the \type {l} table. Each glyph has a description and
+(in this case) one command that defines the virtual shape. The name
+is picked up from the character data table that is present in \MKIV.
+
+As told before we generate multiple instances per requested font
+and here is how it happens. We initialize the \type {mfplain}
+format and reset it afterwards. The punk definition file is
+adapted for multiple runs. Scaling happens here because later on
+the scaler has no knowledge about what is present in the commands.
+We use a few helpers for processing the \METAPOST\ code and format
+the final font table in a way \CONTEXT\ \MKIV\ likes. Currently
+the parameters (font dimensions) are rather hard coded, but this
+will change when \MPLIB\ can provide them.
+
+\starttyping

+        statistics.stoptiming(flusher)
+    end
+    variants = variants + #lists
+    statistics.stoptiming(metapost.characters)
+    return lists
+end
+\stoptyping
+
+We're not yet there. This was just a font generator that returns
+a list of fonts defined in a format liked by \MKIV\ and not that
+far from what \TEX\ wants back from us. Next we define the
+main definition function, the one that is called when the font
+is defined as virtual font. The special number \type {-1000}
+tells the scaler to honour the designsize, which boils down to
+no scaling, but just copying to the final  table that is passed
+to \TEX. The \type {define} function returns an id which we will
+use later.
+
+The scaler uses the \type {descriptions} to add dimensions (and other data
+needed) in the \type {characters} table. This is something \MKIV\ specific.
+
+\starttyping
+function fonts.handlers.vf.combiner.commands.metafont(g,v)
+    local size = g.specification.size
+    local data = metapost.characters.process(v[2],v[3],v[4],size/655360)
+    local list, t = { }, { }
+    for d=1,#data do
+        t = data[d]
+        t = fonts.constructors.scale(t, -1000)
+        t.id = font.define(t)
+        list[#list+1] = t.id
+    end
+    for k, v in pairs(t) do
+        g[k] = v -- kind of replace, when not present, make nil
+    end
+    g.variants = list
+end
+\stoptyping
+
+We hook this into the \CONTEXT\ font handler and from now on
+the \type {@punk} is recognized:
+
+\starttyping
+fonts.definers.methods.install( "punk", { { "metafont", "mfplain", "punkfont.mp", 10 } } )
+\stoptyping
+
+Now that we can define the font, we need to deal with
+the randomizer. This is optional fun. The mentioned case swappers
+are implemented in the \type {cases} namespace:
+
+\starttyping
+local fontdata = fonts.hashes.identifiers
+
+cases.actions[99] = function(current)
+    local c = current.char
+    local used = fontdata[current.font].variants
+    if used then
+        local f = math.random(1,#used)
+        current.font = used[f]
+        return current, true
+    else
+        return current, false
+    end
+end
+\stoptyping
+
+This function is called in one of the passes over the node
+list. Thanks to this framework we don't need that much code.
+We didn't show two statistics functions. They are the reason why
+we keep track of the total number of glyphs defined.
+
+This leaves us defining the interface, so here we go:
+
+\starttyping
+\def\StartRandomPunk{\begingroup\setcharactercasing[99]}
+\def\StopRandomPunk {\endgroup}
+\stoptyping
+
+The set command just sets the attribute that we associated
+with casing (one of the many attributes). The number 99 is
+rather arbitrary.
+
+If you follow the development of \LUATEX\ and \MKIV\ (we do talks at
+conferences, keep track of the development history in \type {mk.pdf},
+and report on the \CONTEXT\ mailing list) you will have noticed  that
+we often use somewhat extreme examples to explore and test the
+functionality and this is no exception. As usual it helped us to improve
+the code and extend our todo list. Can the previous code convince
+the grand wizards to start using \LUATEX ? Probably not. Let's
+anyway hope that they will put the addition of punk math to their todo
+list. In the meantime we've already started adding missing characters:
+
+\startlinecorrection[blank]
+    \hbox to \hsize \bgroup \hss % { ' \ " }
+        \dorecurse{6}{\hbox{\char123\enspace\char39\enspace\char92\enspace\char34\enspace\char125}\quad}\unskip
+    \hss \egroup
+\stoplinecorrection
+
+Also, because we can be sure that Mojca Miklavec's first test will
+be if her favourite characters \color [mkcolor] {\ccaron}, \color
+[mkcolor] {\scaron} and \color [mkcolor] {\zcaron} are supported,
+we made sure that we composed those accented characters as well.
+\footnote {This is accomplished by adding \type
+{composecharacters(t)} at an undisclosed location in
+the previous code.}

+\chapter {The luafication of \TEX\ and \CONTEXT}
+
+% (Previously published in \TUGBOAT, ask Karl for reference.)
+
+\subject {introduction}
+
+Here I will present the current stage of \LUATEX\ around beta
+stage 2, and discuss the impact so far on \CONTEXT\ \MKIV\
+that we use as our testbed. I'm writing this at the end of February
+2008 as part of the series of regular updates on \LUATEX. As such,
+this report is part of our more or less standard test document
+(\type{mk.tex}). More technical details can be found in the reference
+manual that comes with \LUATEX. More information on \MKIV\ is
+available in the \CONTEXT\ mailing lists, \WIKI, and
+\type{mk.pdf}.
+
+For those who never heard of \LUATEX: this is a new variant of
+\TEX\ where several long pending wishes are fulfilled:
+
+\startitemize[packed]
+\item combine the best of all \TEX\ engines
+\item add scripting capabilities
+\item open up the internals to the scripting engine
+\item enhance font support to \OPENTYPE
+\item move on to \UNICODE
+\item integrate \METAPOST
+\stopitemize
+
+There are a few more wishes, like converting the code base to
+\CCODE\ but these are long term goals.
+
+The project started a few years ago and is conducted by Taco
+Hoekwater (\PASCAL\ and \CCODE\ coding, code base management,
+reference manual), Hartmut Henkel (\PDF\ backend, experimental
+features) and Hans Hagen (general overview, \LUA\ and \TEX\
+coding, website). The code development got a boost by a grant of
+the Oriental \TEX\ project (project lead: Idris Samawi Hamid) and
+funding via the \TUG. The related \MPLIB\ project by the same team
+is also sponsored by several user groups. The very much needed
+\OPENTYPE\ fonts are also a user group funded effort: the Latin
+Modern and \TEX\ Gyre projects (project leads: Jerzy Ludwichowski,
+Volker RW\ Schaa and Hans Hagen), with development (the real
+work) by: Bogus\l{}aw Jackowski and Janusz Nowacki.
+
+One of our leading principles is that we focus on opening up. This
+means that we don't implement solutions (which also saves us many
+unpleasant and everlasting discussions). Implementing solutions is
+up to the user, or more precisely: the macro package writer, and
+since there are many solutions possible, each can do it his or her
+way. In that sense we follow the footsteps of Don Knuth: we make
+an extensible tool, you are free to like it or not, you can take
+it and extend it where needed, and there is no need to bother us
+(unless of course you find bugs or weird side effects). So far
+this has worked out quite well and we're confident that we can keep
+our schedule.
+
+We do our tests of a variant of \CONTEXT\ tagged \MKIV, especially
+meant for \LUATEX, but \LUATEX\ itself is in no way limited to or
+tuned for \CONTEXT. Large chunks of the code written for \MKIV\
+are rather generic and may eventually be packaged as a base system
+(especially font handling) so that one can use \LUATEX\ in rather
+plain mode. To a large extent \MKIV\ will be functionally compatible
+with \MKII, the version meant for traditional \TEX, although it
+knows how to profit from \XETEX. Of course the expectation is that
+certain things can be done better in \MKIV\ than in \MKII.
+
+\subject{status}
+
+By the end of 2007 the second major beta release of \LUATEX\ was
+published. In the first quarter of 2008 Taco would concentrate on
+\MPLIB, Hartmut would come up with the first version of the image
+library while I could continue working on \MKIV\ and start using
+\LUATEX\ in real projects. Of course there is some risk involved
+in that, but since we have a rather close loop for critical bug
+fixes, and because I know how to avoid some dark corners, the
+risk was worth taking.
+
+What did we accomplish so far? I can best describe this in relation
+to how \CONTEXT\ \MKIV\ evolved and will evolve. Before we do this,
+it makes sense to spend some words on why we started working on \MKIV\
+in the first place.
+
+When the \LUATEX\ project started, \CONTEXT\ was about 10 years in
+the field. I can safely say that we were still surprised by the
+fact that what at first sight seems unsolvable in \TEX\ somehow
+could always be dealt with. However, some of the solutions were
+rather tricky. The code evolved towards a more or less stable
+state, but sometimes depended on controlled processing. Take for
+instance backgrounds that can span pages and columns, can be
+nested and can have arbitrary shapes. This feature has been
+present in \CONTEXT\ for quite a while, but it involves an
+interplay between \TEX\ and \METAPOST. It depends on information
+collected in a previous run as well as (at runtime or not)
+processing of graphics.
+
+This means that by now \CONTEXT\ is not just a bunch of \TEX\ macros,
+but also closely related to \METAPOST. It also means that
+processing itself is by now rather controlled by a wrapper, in the
+case of \MKII\ called \TEXEXEC. It may sound complicated, but the
+fact that we have implemented workflows that run unattended for
+many years and involve pretty complex layouts and graphic
+manipulations demonstrates that in practice it's not as bad as it
+may sound.
+
+With the arrival of \LUATEX\ we not only have a rigourously
+updated \TEX\ engine, but also get \METAPOST\ integrated. Even
+better, the scripting language \LUA\ is not only used for opening
+up \TEX, but is also used for all kind of management tasks. As
+a result, the development of \MKIV\ not only concerns rewriting
+whole chunks of \CONTEXT, but also results in a set of new
+utilities and a rewrite of existing ones. Since dealing with
+\MKIV\ will demand some changes in the way users deal with
+\CONTEXT\ I will discuss some of them first. It also demonstrates
+that \LUATEX\ is more than just \TEX.
+
+\subject{utilities}
+
+There are two main scripts: \LUATOOLS\ and \MTXRUN. The first one
+started as a replacement for \KPSEWHICH\ but evolved into a base
+tool for generating (\TDS) file databases and generating formats.
+In \MKIV\ we replace the regular file searching, and therefore we
+use a different database model. That's the easy part. More
+tricky is that we need to bootstrap \MKIV\ into this alternative
+mode and when doing so we don't want to use the \type {kpse} library
+because that would trigger loading of its databases. To discuss
+the gory details here might cause users to refrain from using \LUATEX\ so
+we stick to a general description.
+
+\startitemize
+\item When generating a format, we also generate a bootstrap \LUA\
+      file. This file is compiled to bytecode and is put alongside
+      the format file. The libraries of this bootstrap file are
+      also embedded in the format.
+\item When we process a document, we instruct \LUATEX\ to load
+      this bootstrap file before loading the format. After the
+      format is loaded, we re-initialize the embedded libraries.
+      This is needed because at that point more information may be
+      available than at loading time. For instance, some
+      functionality is available only after the format is loaded
+      and \LUATEX\ enters the \TEX\ state.
+\item File databases, formats, bootstrap files, and
+      runtime|-|generated cached data is kept in a \TDS\ tree specific cache
+      directory. For instance, \OPENTYPE\ font tables are stored
+      on disk so that next time loading them is faster.

+Starting \LUATEX\ and \MKIV\ is done by \LUATOOLS. This tool
+is generic enough to handle other formats as well, like \MPTOPDF\
+or \PLAIN. When you run this script without argument, you will

+
+For the \LUA\ based file searching, \LUATOOLS\ can be seen as a
+replacement for \MKTEXLSR\ and \KPSEWHICH\ and as such it also
+recognizes some of the \KPSEWHICH\ flags. The script is self
+contained in the sense that all needed libraries are embedded. As
+a result no library paths need to be set and packaged. Of course
+the script has to be run using \LUATEX\ itself. The following
+commands generate the file databases, generate a \CONTEXT\ \MKIV\
+format, and process a file:
+
+\starttyping
+luatools --generate
+luatools --make --compile cont-en
+luatools --fmt=cont-en somefile.tex
+\stoptyping
+
+There is no need to install \LUA in order to run this script. This
+is because \LUATEX\ can act as such with the advantage that the
+built-in libraries are available too, for instance the \LUA\ file
+system \type {lfs}, the \ZIP\ file manager \type {zip}, the
+\UNICODE\ libary \type {unicode}, \type {md5}, and of course some of
+our own.

+In principle \type {luatex} can perform all tasks but because we

+
+The second script, \MTXRUN, can be seen as a replacement for the
+\RUBY\ script \TEXMFSTART, a utility whose main task is to launch
+scripts (or documents or whatever) in a \TDS\ tree. The \MTXRUN\
+script makes it possible to get away from installing \RUBY\ and as

+This help information gives an impression of what the script does:

+and either conditionally or not. Users of \CONTEXT\ will probably
+recognize most of the flags. As with \TEXMFSTART, arguments with
+prefixes like \type{file:} will be resolved before being

+
+The first option, \type {--script} is the most important one and

+In \MKIV\ font names can be prefixed by \type {file:} or \type
+{name:} and when they are resolved, several attempts are made, for
+instance non|-|characters are ignored. The \type {--all} flag shows
+more variants.
+
+Another example is:
+
+\starttyping
+mtxrun --script context --ctx=somesetup somefile.tex
+\stoptyping
+
+Again, users of \TEXEXEC\ may recognize part of this and indeed this is
+its replacement. Instead of \TEXEXEC\ we use a script named \type
+{mtx-context.lua}. Currently we have the following scripts and
+more will follow:
+
+The \type {babel} script is made in cooperation with Thomas
+Schmitz and can be used to convert babelized Greek files into
+proper \UTF. More of such conversions may follow. With \type
+{cache} you can inspect the content of the \MKIV\ cache and do
+some cleanup. The \type {chars} script is used to construct some
+tables that we need in the process of development. As its name
+says, \type {check} is a script that does some checks, and in
+particular it tries to figure out if \TEX\ files are correct. The
+already mentioned \type {context} script is the \MKIV\ replacement
+of \TEXEXEC, and takes care of multiple runs, preloading project
+specific files, etc. The \type {convert} script will replace the
+\RUBY\ script \type {pstopdf}.
+
+A rather important script is the already mentioned \type {fonts}.
+Use this one for generating font name databases (which then
+permits a more liberal access to fonts) or identifying installed
+fonts. The \type {unzip} script indeed unzips archives. The \type
+{update} script is still somewhat experimental and is one of the
+building blocks of the \CONTEXT\ minimal installer system by
+Mojca Miklavec and Arthur Reutenauer. This update script
+synchronizes a local tree with a repository and keeps an
+installation as small as possible, which for instance means: no
+\OPENTYPE\ fonts for \PDFTEX, and no redundant \TYPEONE\ fonts for
+\LUATEX\ and \XETEX.
+
+The (for the moment) last two scripts are \type {watch} and \type
+{web}. We use them in (either automated or not) remote publishing
+workflows. They evolved out of the \EXAMPLE\ framework which is
+currently being reimplemented in \LUA.
+
+As you can see, the \LUATEX\ project and its \CONTEXT\ companion
+\MKIV\ project not only deal with \TEX\ itself but also
+facilitates managing the workflows. And the next list is
+just a start.

+
+There will be more scripts. These scripts are normally rather small
+because they hook into \MTXRUN\ which provides the libraries. Of course
+existing tools remain part of the toolkit. Take for instance \CTXTOOLS,
+a \RUBY\ script that converts font encoded pattern files to generic
+\UTF\ encoded files.
+
+Those who have followed the development of \CONTEXT\ will notice that we moved
+from utilities written in \MODULA\ to tools written in \PERL. These were later
+replaced by \RUBY\ scripts and eventually most of them will be rewritten in
+\LUA.
+
+\subject{macros}
+
+I will not repeat what is said already in the \MKIV\ related
+documents, but stick to a summary of what the impact on \CONTEXT\
+is and will be. From this you can deduce what the possible influence
+on other macro packages can be.
+
+Opening up \TEX\ started with rewriting all \IO\ related activities.
+Because we wanted to be able to read from \ZIP\ files, the web and
+more, we moved away from the traditional \KPSE\ based file
+handling. Instead \MKIV\ uses an extensible variant written in
+\LUA. Because we need to be downward compatible, the code is
+somewhat messy, but it does the job, and pretty quickly and efficiently
+too. Some alternative input media are implemented and many more
+can be added. In the beginning I permitted several ways to specify
+a resource but recently a more restrictive \URL\ syntax was
+imposed. Of course the file locating mechanisms provide the same
+control as provided by the file readers in \MKII.
+
+An example of reading from a \ZIP\ file is:
+
+\starttyping
+\input zip:///archive.zip?name=blabla.tex
+\input zip:///archive.zip?name=/somepath/blabla.tex
+\stoptyping
+
+In addition one can register files, like:
+
+\starttyping
+\usezipfile[archive.zip]
+\usezipfile[tex.zip][texmf-local]
+\usezipfile[tex.zip?tree=texmf-local]
+\stoptyping
+
+The last two variants register a zip file in the \TDS\ structure
+where more specific lookup rules apply. The files in a
+registered file are known to the file searching mechanism so one
+can give specifications like the following:
+
+\starttyping
+\input */blabla.tex
+\input */somepath/blabla.tex
+\stoptyping
+
+In a similar fashion one can use the \type {http}, \type {ftp} and
+other protocols. For this we use independent fetchers that cache
+data in the \MKIV\ cache. Of course, in more structured projects,
+one will seldom use the \type {\input} command but use a project
+structure instead.
+
+Handling of files rather quickly reached a stable state, and we seldom need
+to visit the code for fixes. Already after a few years of developing the first
+code for \LUATEX\ we reached a state of \quote {Hm, when did I write
+this?}. When we have reached a stable state I foresee that much of the
+older code will need a cleanup.
+
+Related to reading files is the sometimes messy area of input
+regimes (file encoding) and font encoding, which itself relates to
+dealing with languages. Since \LUATEX\ is \UTF-8 based, we need to
+deal with file encoding issues in the frontend, and this is what
+\LUA\ based file handling does. In practice users of \LUATEX\ will
+swiftly switch to \UTF\ anyway but we provide regime control for
+historic reasons. This time the recoding tables are \LUA\ based
+and as a result \MKIV\ has no regime files. In a similar fashion
+font encoding is gone: there is still some old code that deals
+with default fallback characters, but most of the files are gone.
+The same will be true for math encoding. All information is now
+stored in a character table which is the central point in many
+subsystems now.
+
+It is interesting to notice that until now users have never asked
+for support with regards to input encoding. We can safely assume
+that they just switched to \UTF\ and recoded older documents. It
+is good to know that \LUATEX\ is mostly \PDFTEX\ but also
+incorporates some features of \OMEGA. The main reason for this is
+that the Oriental \TEX\ project needed bidirectional typesetting
+and there was a preference for this implementation over the one provided by
+\ETEX. As a side effect input translation is also present, but
+since no one seems to use it, that may as well go away. In \MKIV\
+we refrain from input processing as much as possible and focus on
+processing the node lists. That way there is no interference
+between user data, macro expansion and whatever may lead to the
+final data that ends up in the to|-|be|-|typeset stream. As said, users
+seem to be happy to use \UTF\ as input, and so there is hardly any need
+for manipulations.
+
+Related to processing input is verbatim: a feature that is always
+somewhat complicated by the fact that one wants to typeset a
+manual about \TEX\ in \TEX\ and therefore needs flexible escapes
+from illustrative as well as real \TEX\ code. In \MKIV\ verbatim
+as well as all buffering of data is dealt with in \LUA. It took a
+while to figure out how \LUATEX\ should deal with the concept of a
+line ending, but we got there. Right from the start we made sure
+that \LUATEX\ could deal with collections of catcode settings
+(those magic states that characters can have). This means that one
+has complete control at both the \TEX\ and \LUA\ end over the way
+characters are dealt with.
+
+In \MKIV\ we also have some pretty printing features, but many
+languages are still missing. Cleaning up the premature verbatim code
+and extending pretty printing is on the agenda for the end of 2008.
+
+Languages also are handled differently. A major change is that
+pattern files are no longer preloaded but read in at runtime.
+There is still some relation between fonts and languages, no
+longer in the encoding but in dealing with \OPENTYPE\ features.
+Later we will do a more drastic overhaul (with multiple name
+schemes and such). There are a few experimental features, like
+spell checking.
+
+Because we have been using \UTF\ encoded hyphenation patterns for
+quite some time now, and because \CONTEXT\ ships with its own files,
+this transition probably went unnoticed, apart maybe from a faster
+format generation and less startup time.
+
+Most of these features started out as an experiment and provided a
+convenient way to test the \LUATEX\ extensions. In \MKIV\ we go
+quite far in replacing \TEX\ code by \LUA, and how far one goes is
+a matter of taste and ambition. An example of a recent replacement
+is graphic inclusion. This is one of the oldest mechanisms in
+\CONTEXT\ and it has been extended many times, for instance by
+plugins that deal with figure databases (selective filtering from
+\PDF\ files made for this purpose), efficient runtime conversion,
+color conversion, downsampling and product dependent alternatives.
+
+One can question if a properly working mechanism should be
+replaced. Not only is there hardly any speed to gain (after all,
+not that many graphics are included in documents), a \LUA--\TEX\
+mix may even look more complex. However, when an opened-up \TEX\
+keeps evolving at the current pace, this last argument becomes
+invalid because we can no longer give that \TeX ie code to \LUA. Also,
+because most of the graphic inclusion code deals with locating
+files and figuring out the best quality variant, we can benefit
+much from \LUA: file handling is more robust, the code looks
+cleaner, complex searches are faster, and eventually we can
+provide way more clever lookup schemes. So, after all, switching
+to \LUA\ here makes sense. A nice side effect is that some of the
+mentioned plugins now take a few lines of extra code instead of
+many lines of \TEX. At the time of writing this, the beta version
+of \MKIV\ has \LUA\ based graphic inclusion.
+
+A disputable area for Luafication is multipass data. Most of that has
+already been moved to \LUA\ files instead of \TEX\ files, and the
+rest will follow: only tables of contents still use a \TEX\
+auxiliary file. Because at some point we will reimplement the
+whole section numbering and cross referencing, we postponed that
+till later. The move is disputable because in the end, most data
+ends up in \TEX\ again, which involves some conversion. However, in
+\LUA\ we can store and manipulate information much more easily and so
+we decided to follow that route. As a start, index information is
+now kept in \LUA\ tables, sorted on demand, depending on language
+needs and such. Positional information used to take up much hash
+space which could deplete the memory pool, but now we can have
+millions of tracking points at hardly any cost.
+
+Because it is a quite independent task, we could rewrite the
+\METAPOST\ conversion code in \LUA\ quite early in the
+development. We got smaller and cleaner code, more flexibility, and
+also gained some speed. The code involved in this may change as
+soon as we start experimenting with \MPLIB. Our expectations
+are high because in a bit more modern designs a graphic engine
+cannot be missed. For instance, in educational material,
+backgrounds and special shapes are all over the place, and we're
+talking about many \METAPOST\ runs then. We expect to bring down the
+processing time of such documents considerably, if only because
+the \METAPOST\ runtime will be close to zero (as experiments have
+shown us).
+
+While writing the code involved in the \METAPOST\ conversion a new
+feature showed up in \LUA: \type {lpeg}, a parsing library. From
+that moment on \type {lpeg} was being used all over the place,
+most noticeably in the code that deals with processing \XML. Right
+from the start I had the feeling that \LUA\ could provide a more
+convenient way to deal with this input format. Some experiments
+with rewriting the \MKII\ mechanisms did not show the expected
+speedup and were abandoned quickly.
+
+Challenged by \type {lpeg} I then wrote a parser and started
+playing with a mixture of a tree based and stream approach to
+\XML\ (\MKII\ is mostly stream based). Not only is loading \XML\
+code extremely fast (we used 40~megaByte files for testing),
+dealing with the tree is also convenient. The additional \MKIV\
+methods are currently being tested in real projects and so far
+they result in an acceptable and pleasant mix of \TEX\ and \XML. For
+instance, we can now selectively process parts of the tree using
+path expressions, hook in code, manipulate data, etc.
+
+The biggest impact of \LUATEX\ on the \CONTEXT\ code base is not
+the previously mentioned mechanisms but one not yet mentioned:
+fonts. Contrary to \XETEX, which uses third party libraries,
+\LUATEX\ does not implement dealing with font specific issues at
+all. It can load several font formats and accepts font data in a
+well|-|defined table format. It only processes character nodes into
+glyph nodes and it's up to the user to provide more by
+manipulating the node lists. Of course there is still basic
+ligature building and kerning available but one can bypass that with
+other code.
+
+In \MKIV, when we deal with \TYPEONE\ fonts, we try to get away
+from traditional \TFM\ files and use \AFM\ files instead (indeed,
+we parse them using \type {lpeg}). The fonts are mapped onto
+\UNICODE. Awaiting extensions of math we only use \TFM\ files for
+math fonts. Of course \OPENTYPE\ fonts are dealt with and this is
+where we find most \LUA\ code in \MKIV: implementing features.
+Much of that is a grey area but as part of the Oriental \TEX\
+project we're forced to deal with complex feature support, so that
+provides a good test bed as well as some pressure for getting it
+done. Of course there is always the question to what extent we
+should follow the (maybe faulty) other programs that deal with
+font features. We're lucky that the Latin Modern and \TEX\ Gyre
+projects provide real fonts as well as room for discussion and
+exploring these grey areas.
+
+In parallel to writing this, I made a tracing feature for Oriental
+\TEX er Idris so that he could trace what happened with the Arabic
+fonts that he is making. This was relatively easy because already
+in an early stage of \MKIV\ some debugging mechanisms were built.
+One of its nice features is that on an error, or when one
+traces something, the results will be shown in a web browser.
+Unfortunately I have not enough time to explore such aspects in
+more detail, but at least it demonstrates that we can change some
+aspects of the traditional interaction with \TEX\ in more radical
+ways.
+
+Many users may be aware of the existence of so|-|called virtual
+fonts, if only because it can be a cause of problems (related to
+map files and such). Virtual fonts have a lot of potential but
+because they were related to \TEX's own font data format they never got
+very popular. In \LUATEX\ we can make virtual fonts at runtime. In
+\MKIV\ for instance we have a feature (we provide features beyond
+what \OPENTYPE\ does) that completes a font by composing missing
+glyphs on the fly. More of this trickery can be expected as soon
+as we have time and reason to implement it.
+
+In \PDFTEX\ we have a couple of font related goodies, like
+character expansion (inspired by Hermann Zapf) and character
+protruding. There are a few more but these had limitations and
+were suboptimal and therefore have been removed from \LUATEX.
+After all, they can be implemented more robustly in \LUA. The two
+mentioned extensions have been (of course) kept and have been partially
+reimplemented so that they are now uniquely bound to fonts
+(instead of being common to fonts that traditional \TEX\ shares in
+memory). The character related tables can be filled with \LUA\ and
+this is what \MKIV\ now does. As a result much \TEX\ code could go
+away. We still use shape related vectors to set up the values, but
+we also use information stored in our main character database.
+
+A likely area of change is math and not only as a result of the
+\TEX\ gyre math project which will result in a bunch of \UNICODE\
+compliant math fonts. Currently in \MKIV\ the initialization
+already partly takes place using the character database, and so
+again we will end up with less \TEX\ code. A side effect of
+removing encoding constraints (i.e.\ moving to \UNICODE) is that
+things get faster. Later this year math will be opened up.
+
+One of the biggest impacts of opening up is the arrival of
+attributes. In traditional \TEX\ only glyph nodes have an
+attribute, namely the font id. Now all nodes can have attributes,
+many of them. We use them to implement a variety of features that
+already were present in \MKII, but used marks instead: color (of
+course including color spaces and transparency), inter|-|character
+spacing, character case manipulation, language dependent pre and
+post character spacing (for instance after colons in French),
+special font rendering such as outlines, and much more. An
+experimental application is a more advanced glue|/|penalty model
+with look|-|back and look|-|ahead as well as relative weights. This
+is inspired by the one good thing that \XML\ formatting objects
+provide: a spacing and pagebreak model.
+
+It does not take much imagination to see that features demanding
+processing of node lists come with a price: many of the
+callbacks that \LUATEX\ provides are indeed used and as a result
+quite some time is spent in \LUA. You can add to that the time
+needed for handling font features, which also boils down to
+processing node lists. The second half of 2007 Taco and I spent
+much time on benchmarking and by now the interface between \TEX\
+and \LUA\ (passing information and manipulating nodes) has been
+optimized quite well. Of course there's always a price for
+flexibility and \LUATEX\ will never be as fast as \PDFTEX, but
+then, \PDFTEX\ does not deal with \OPENTYPE\ and such.
+
+We can safely conclude that the impact of \LUATEX\ on \CONTEXT\ is
+huge and that fundamental changes take place in all key
+components: files, fonts, languages, graphics, \METAPOST\, \XML,
+verbatim and color to start with, but more will follow. Of course
+there are also less prominent areas where we use \LUA\ based
+approaches: handling \URL's, conversions, alternative math
+input to mention a few. Sometime in 2009 we expect to start
+working on more fundamental typesetting related issues.

+\subject{roadmap}
+
+On the \LUATEX\ website \type {www.luatex.org} you can find a
+roadmap. This roadmap is just an indication of what happened and
+will happen and it will be updated when we feel the need. Here is
+a summary.
+
+\startitemize
+
+\head merging engines
+
+Merge some of the \ALEPH\ codebase into \PDFTEX\ (which already has
+\ETEX) so that \LUATEX\ in \DVI\ mode behaves like \ALEPH, and in
+\PDF\ mode like \PDFTEX. There will be \LUA\ callbacks for file
+searching. This stage is mostly finished.
+
+\head \OPENTYPE\ fonts
+
+Provide \PDF\ output for \ALEPH\ bidirectional functionality and add
+support for \OPENTYPE\ fonts. Allow \LUA\ scripts to control all
+aspects of font loading, font definition and manipulation. Most of
+this is finished.
+
+\head tokenizing and node lists
+
+Use \LUA\ callbacks for various internals, complete access to
+tokenizer and provide access to node lists at moments that make
+sense. This stage is completed.
+
+\head paragraph building
+
+Provide control over various aspects of paragraph building
+(hyphenation, kerning, ligature building), dynamic loading loading
+of hyphenation patterns. Apart from some small details these
+objectives are met.
+
+\head \METAPOST\ (\MPLIB)
+
+Incorporate a \METAPOST\ library and investigate options for runtime
+font generation and manipulation. This activity is on schedule and
+integration will take place before summer 2008.
+
+\head image handling
+
+Image identification and loading in \LUA\ including scaling and
+object management. This is nicely on schedule, the first version of the
+image library showed up in the 0.22 beta and some more features
+are planned.
+
+\head special features
+
+Cleaning up of \HZ\ optimization and protruding and getting rid of
+remaining global font properties. This includes some cleanup of
+the backend. Most of this stage is finished.
+
+\head page building
+
+Control over page building and access to internals that matter.
+Access to inserts. This is on the agenda for late 2008.
+
+\head \TEX\ primitives
+
+Access to and control over most \TEX\ primitives (and related
+mechanisms) as well as all registers. Especially box handling
+has to be reinvented. This is an ongoing effort.
+
+\head \PDF\ backend
+
+Open up most backend related features, like annotations and
+object management. The first code will show up at the end of 2008.
+
+\head math
+
+Open up the math engine parallel to the development of
+the \TEX\ Gyre math fonts. Work on this will start during 2008 and
+we hope that it will be finished by early 2009.
+
+\head \CWEB
+
+Convert the \TEX\ Pascal source into \CWEB\ and start using \LUA\
+as glue language for components. This will be tested on \MPLIB\
+first. This is on the long term agenda, so maybe around 2010 you
+will see the first signs.
+
+\stopitemize
+
+In addition to the mentioned functionality we have a couple of
+ideas that we will implement along the road. The first formal beta
+was released at \TUG\ 2007 in San Diego (\USA). The first
+formal release will be at \TUG\ 2008 in Cork (Ireland). The
+production version will be released at Euro\TEX\ in the
+Netherlands (2009).
+
+
+Eventually \LUATEX\ will be the successor to \PDFTEX\ (informally
+we talk of \PDFTEX\ version~2). It can already be used as a
+drop|-|in for \ALEPH\ (the stable variant of \OMEGA). It provides a
+scripting engine without the need to install a specific scripting
+environment. These factors are among the reasons why distributors
+have added the binaries to the collections. Norbert Preining
+maintains the \LINUX\ packages, Akira Kakuto provides \WINDOWS\
+binaries as part of his distribution, Arthur Reutenauer takes care
+of \MACOSX\ and Christian Schenk recently added \LUATEX\ to \MIKTEX.
+The \LUATEX\ and \MPLIB\ projects are hosted at Supelec by Fabrice
+Popineau (one of our technical consultants). And with Karl Berry
+being one of our motivating supporters, you can be sure that the
+binaries will end up someplace in \TEXLIVE\ this year.

+\chapter{Everything structure}
+
+At the time of this writing, \CONTEXT\ \MKIV\ spends some 50\% of
+its time in \LUA. There are several reasons for this.
+
+\startitemize[packed]
+\item All \IO\ goes via \LUA, including messages and logging. This includes
+      file searching which happened to be done by the \KPSE\ library.
+\item Much font handling is done by \LUA\ too, for instance \OPENTYPE\ features
+      are completely handled by \LUA.
+\item Because \TEX\ is highy optimized, its influence on runtime is less
+      prominent. Even if we delegate some tasks to \LUA, \TEX\ still has
+      work to do.
+\stopitemize
+
+Among the reported statistics of a 242 page version of \type
+{mk.pdf} (not containing this chapter) we find the following:
+
+\startntyping
+input load time           - 0.094 seconds
+startup time              - 0.905 seconds (including runtime option file processing)
+jobdata time              - 0.140 seconds saving, 0.062 seconds loading
+fonts load time           - 5.413 seconds
+xml load time             - 0.000 seconds, lpath calls: 46, cached calls: 31
+lxml load time            - 0.000 seconds preparation, backreferences: 0
+mps conversion time       - 0.000 seconds
+node processing time      - 1.747 seconds including kernel
+kernel processing time    - 0.343 seconds
+attribute processing time - 2.075 seconds
+language load time        - 0.109 seconds, n=4
+graphics processing time  - 0.109 seconds including tex, n=7
+metapost processing time  - 0.484 seconds, loading: 0.016 seconds, execution: 0.203 seconds, n: 65
+current memory usage      - 332 MB
+loaded patterns           - gb:gb:pat:exc:3 nl:nl:pat:exc:4 us:us:pat:exc:2
+control sequences         - 34245 of 165536
+callbacks                 - direct: 235579, indirect: 18665, total: 254244 (1050 per page)
+runtime                   - 25.818 seconds, 242 processed pages, 242 shipped pages, 9.373 pages/second
+\stopntyping
+
+The startup time includes initial font loading (we don't store fonts
+in the format). Jobdata time involves loading and saving multipass data
+used for tables of contents, references, positioning, etc. The time needed
+for loading fonts is over 5 seconds due to the fact that we load a couple of
+real large and complex fonts. Node processing time mostly is related to
+\OPENTYPE\ feature support. The kernel processing time refers to hyphenation
+and line breaking, for which (of course) we use \TEX. Direct callbacks are
+implicit calls to \LUA, using \type {\directlua} while the indirect calls
+concern overloaded \TEX\ functions and callbacks triggered by \TEX\ itself.
+
+Depending on the system load on my laptop, the throughput is around
+10 pages per second for this document, which is due to the fact
+that some font trickery takes place using a few arabic fonts, some
+chinese, a bunch of metapost punk instances, Zapfino, etc.
+
+The times reported are accumulated times and contain quite some
+accumulated rounding errors so assuming that the operating system
+rounds up the times, the totals in practice might be higher. So,
+looking at the numbers, you might wonder if the load on \LUA\ will
+become even larger. This is not necessary. Some tasks can be done
+better in \LUA\ but not always with less code, especially when we
+want to extend functionality and to provide more robust solutions.
+Also, even if we win some processing time we might as well waste
+it in interfacing between \TEX\ and \LUA. For instance, we can
+delegate pretty printing to \LUA, but most documents don't contain
+verbatim at all. We can handle section management by \LUA, but how
+many section headers does a document have?
+
+When the future of \TEX\ is discussed, among the ideas presented
+is to let \TEX\ stick to typesetting and implement it as a
+component (or library) on top of a (maybe dedicated) language.
+This might sound like a nice idea, but eventually we will end up
+with some kind of user interface and a substantial amount of code
+dedicated to dealing with fonts, structure, character management,
+math etc.
+
+In the process of converting \CONTEXT\ to \MKIV\ we try to use
+each language (\TEX, \LUA, \METAPOST) for what it is best suited
+for. Instead of starting from scratch, we start with existing code
+and functionality, because we need a running system. Eventually we
+might find \TEX's role as language being reduced to (or maybe we can
+better talk of \quote {focused on}) mostly aspects of
+typesetting, but \CONTEXT\ as a whole will not be much different
+from the perspective of the user.
+
+So, this is how the transition of \CONTEXT\ takes place:
+
+\startitemize[packed]
+\item We started with replacing isolated bits and pieces of code
+      where \LUA\ is a more natural candidate, like file \IO, encoding
+      issues.
+\item We implement new functionality, for instance \OPENTYPE\
+      and \TYPEONE\ support.
+\item We reimplement mechanisms that are not efficient as we want them
+      to be, like buffers and verbatim.
+\item We add new features, for instance tree based \XML\ processing.
+\item After evaluating we reimplement again when needed (or when \LUATEX\
+      evolves).
+\stopitemize
+
+Yet another transition is the one we will discuss next:
+
+\startitemize[packed]
+\item We replace complex mechanisms by new ones where we separate
+      management and typesetting.
+\stopitemize
+
+This not so trivial effort because it affects many aspects of \CONTEXT\ and
+as such we need to adapt a lot of code at the same time: all things
+related to structure:
+
+\startitemize[packed]
+\item sectioning (chapters, sections, etc)
+\item numbering (pages, itemize, enumeration, floats, etc)
+\item marks (used for headers and footers)
+\item lists (tables of contents, lists of floats, sorted lists)
+\item registers (including collapsing of page ranges)
+\item cross referencing (to text as well as pages)
+\item notes (footnotes, endnotes, etc)
+\stopitemize
+
+All these mechanisms are somehow related. A section head can occur
+in a list, can be cross referenced, might be shows in a header and
+of course can have a number. Such a number can have multiple
+components (1.A.3) where each component can have its own
+conversion, rendering (fonts, colors) and selectively have less
+components. In tables of contents either or not we want to see all
+components, separators etc. Such a table can be generated at each
+level, which demands filtering mechanisms. The same is true for
+registers. There we have page numbers too, and these may be
+prefixed by section numbers, possibly rendered differently than
+the original section number.
+
+Much if this is possible in \CONTEXT\ \MKII, but the code that
+deals with this is not always nice and clean and right from the start
+of the \LUATEX\ project it has been on the agenda to clean it up. The code
+evolved over time and
+functionality was added when needed. But, the projects
+that we deal with demand more (often local) control over the
+components of a number.
+
+What makes structure related data complex is that we need to keep
+track of each aspect in order to be able to reproduce the
+rendering in for instance a table of contents, where we also may
+want to change some of the aspects (for instance separators in a
+different color). Another pending issue is \XML\ and although we
+could normally deal with this quite well, it started making sense
+to make all multi|-|pass data (registers, tables of content,
+sorted lists, references, etc.) more \XML\ aware. This is a
+somewhat hairy task, if only because we need to switch between
+\TEX\ mode and \XML\ mode when needed and at the same time keep an
+eye on unwanted expansion: do we keep structure in the content or
+not?
+
+Rewriting the code that deals with these aspects of typesetting is
+the first step in a separation of code in \MKII\ and \MKIV. Until
+now we tried to share much code, but this no longer makes sense.
+Also, at the \CONTEXT\ conference in Bohinj (2008) it was decided
+that given the development of \MKIV, it made sense to freeze
+\MKII\ (apart from bug fixes and minor extensions). This decision
+opens the road to more drastic changes. We will roll back some of
+the splits in code that made sharing code possible and just
+replace whole components of \CONTEXT\ as a whole. This also gives
+us the opportunity to review code more drastically than until now
+in the perspective of \ETEX.
+
+Because this stage in the rewrite of \CONTEXT\ might bring some
+compatibility issues with it (especially for users who use the
+more obscure tuning options), I will discuss some of the changes
+here. A bit of understanding might make users more tolerant.
+
+The core data structure that we need to deal with is a number, which
+can be constructed in several ways.

+In this table we see how numbers are composed:
+
+\starttabulate[|l|p|]
+\NC \NotaBeneR{section number} \NC It has several components, separated by symbols
+                                   and with an optional final symbol \NC \NR

+\NC \NotaBeneB{page number}    \NC That can be preceded by a (partial) sectionnumber

+\NC \NotaBeneY{counter}        \NC It can be preceded by a (partial) sectionnumber and
+                                   can also have subnumbers with its own separation
+                                   properties \NC \NR
+\NC \NotaBeneS{symbol}         \NC Sometimes numbers get represented by symbols in which
+                                   case we use pagewise restarting symbol sets \NC \NR
+\stoptabulate
+
+Say that at some point we store a section number and/or page
+number. With the number we need to store information about the
+conversion (number, character, roman numeral, etc) and the
+separators, including their rendering. However, when we reuse that
+stored information we might want to discard some components and/or
+use a different rendering. In traditional \CONTEXT\ we have
+control over some aspects but due to the way numbers are stored
+for later reuse this control is limited.
+
+Say that we have cloned a subsection head as follows:
+
+\starttyping
+\definehead[MyHead][section]
+\stoptyping
+
+This is used as:
+
+\starttyping
+\MyHead[example]{Example}
+\stoptyping
+
+In \MKII\ we save a list entry (which has the number, the title
+and a reference to the page) and a reference to the the number,
+the title and the page (tagged \type {example}). Page numbers are
+stored in such a way that we can filter at specific section
+levels. This permits local tables of contents.
+
+The entry in the multi pass data file looks as follows (we collect all
+multi pass data in one file):
+
+\starttyping
+\mainreference{}{example}{2--0-1-1-0-0-0-0--1}{1}{{I.I}{Example}}%
+\listentry{MyHead}{2}{I.I}{Example}{2--0-1-1-0-0-0-0--1}{1}%
+\stoptyping
+
+In \MKIV\ we store more information and use tables for that. Currently
+the entry looks as follows:
+
+\starttyping
+structure.lists.collected={
+ {
+   ...
+ },
+ {
+  metadata={
+   catcodes=4,
+   coding="tex",
+   internal=2,
+   kind="section",
+   name="MyHead",
+   reference="example",
+  },
+  pagenumber={
+   numbers={ 1, 1, 0 },
+  },
+  sectionnumber={
+   conversion="R",
+   conversionset="default",
+   numbers={ 0, 2 },
+   separatorset="default",
+  },
+  sectiontitle={
+   label="MyHead",
+   title="Example",
+  },
+ },
+ {
+  ...
+ },
+}
+\stoptyping
+
+There can be much more information in each of the subtables. For
+instance, the \type {pagenumber} and \type {sectionnumber}
+subtables can have \type {prefix}, \type {separatorset},
+\type{conversion}, \type {conversionset}, \type {stopper}, \type
+{segments} and \type {connector} fields, and the \type {metadata}
+table can contain information about the \XML\ root document so
+that associated filtering and handling can be reconstructed. With the
+section title we store information about the preceding label text
+(seldom used, think of \quote{Part B}).
+
+This entry is used for lists as well as cross referencing.
+Actually, the stored information is also used for markings
+(running heads). This means that these mechanisms must be able to
+distinguish between where and how information is stored.
+
+These tables look rather verbose and indeed they are. We end up
+with much larger multi|-|pass data files but fortunately loading them
+is quite efficient. Serializing on the other hand might cost some time
+which is compensated by the fact that we no longer store
+information in token lists associated with nodes in \TEX's lists
+and in the future we might even move more data handling to the
+\LUA\ end. Also, in future versions we will share similar data
+(like page number information) more efficiently.
+
+Storing date at the \LUA\ end also has consequences for the
+typesetting. When specific data is needed a call to \LUA\ is
+necessary. In the future we might offer both push and pull methods
+(\LUA\ pushing information to the typesetting code versus \LUA\
+triggering typesetting code). For lists we pull, and for registers
+we currently push. Depending on our experiences we might change
+these strategies.
+
+A side effect of the rewrite is that we force more consistency.
+For instance, you see a \type {conversion} field in the list. This
+is the old way of defining the way a number gets converted. The
+modern approach is to use sets. Because we now have a more
+stringent inheritance model at the user interface level, this
+might lead to incompatible conversions at lower levels (when
+unset). Instead of cooking up some nasty compatibility hacks, we
+accept some incompatibility, if only because users have to adapt
+their styles to new font technology anyway. And for older
+documents there is still \MKII.
+
+Instead of introducing many extra configuration variables (for each
+level of sectioning) we introduce sets. These replace some of the
+existing parameters and are the follow up on some (undocumented)
+precursor of sets. Examples of sets are:
+
+\starttyping
+\definestructureseparatorset [default][][.]
+\definestructureconversionset[default][][numbers]
+\definestructureresetset     [default][][0]
+\definestructureprefixset    [default][section-2,section-3][]
+\definestructureseparatorset [appendix][][.]
+\definestructureconversionset[appendix][Romannumerals,Characters][]
+\definestructureresetset     [appendix][][0]
+\stoptyping
+
+The third parameter is the default value. The sets that relate to typesetting
+can have a rendering specification:
+
+\starttyping
+\definestructureseparatorset
+  [demosep]
+  [demo->!,demo->?,demo->*,demo->@]
+  [demo->/]
+\stoptyping
+
+Here we apply \type{demo} to each of the separators as well as to the
+default. The renderer is defined with:
+
+\starttyping
+\defineprocessor[demo][style=\bfb,color=red]
+\stoptyping
+
+You can imagine that, although this is quite possible in \TEX,
+dealing with sets, splitting them, handling the rendering, etc.\
+is easier in \LUA\ that in \TEX. Of course the code still looks
+somewhat messy, if only because the problem is messy. Part if this
+mess is related to the fact that we might have to specify all
+components that make up a number.
+
+\starttabulate
+\NC section    \NC section number as part of head  \NC \NR
+\NC list       \NC section number as part of list entry  \NC \NR
+\NC            \NC section number as part of page number prefix \NC \NR
+\NC            \NC (optionally prefixed) page number \NC \NR
+\NC counter    \NC section number as part of counter prefix  \NC \NR
+\NC            \NC (optionally prefixed) counter value(s) \NC \NR
+\NC pagenumber \NC section number as part of page number \NC \NR
+\NC            \NC pagenumber components (realpage, page, subpage) \NC \NR
+\stoptabulate
+
+As a result we have upto 3 sets of parameters:
+
+\starttabulate
+\NC section    \NC \type{section*} \NC \NR
+\NC list       \NC \type{section*} \type{prefix*} \type{page*} \NC \NR
+\NC counter    \NC \type{section*} \type{number*} \NC \NR
+\NC pagenumber \NC \type{prefix*} \type{page*} \NC \NR
+\stoptabulate
+
+When reimplementing the structure related commands, we also have
+to take mechanisms into account that relate to them. For instance,
+index sorter code is also used for sorted lists, so when we adapt
+one mechanism we also have to adapt the other. The same is true
+for cross references, that are used all over the place. It helps
+that for the moment we can omit the more obscure interaction
+related mechanism, if only because users will seldom use them.
+Such mechanisms are also related to the backend and we're not yet
+in the stage where we upgrade the backend code. In case you wonder
+why references can be such a problematic areas think of the
+following:
+
+\starttyping
+\goto{here}[page(10),StartSound{ping},StartVideo{demo}]
+\goto{there}[page(10),VideLayer{example},JS(SomeScript{hi world})]
+\goto{anywhere}[url(mypreviouslydefinedurl)]
+\stoptyping
+
+The \CONTEXT\ cross reference mechanism permits mixed usage of simple
+hyperlinks (jump to some page) and more advanced viewer actions like
+showing widgets and runnign \JAVASCRIPT\ code. And even a simple
+reference like:
+
+\starttyping
+\at{here and there}[somefile::sometarget]
+\stoptyping
+
+involves some code because we need to handle the three words as
+well as the outer reference. \footnote {Currently \CONTEXT\ does
+its own splitting of multiword references, and does so by reusing
+hyperlink resources in the backend format. This might change in
+the future.} The reason why we need to reimplement referencing
+along with structure lays in the fact that for some structure
+components (like section headers and float references) we no
+longer store cross reference information separately but filter it
+from the data stored in the list (see example before).
+
+The \LUA\ code involved in dealing with the more complex
+references shown here is much more flexible and robust than the
+original \TEX\ code. This is a typical example of where the
+accumulated time spent on the \TEX\ based solution is large
+compared to the time spent on the \LUA\ variant. It's like driving
+200 km by car through hilly terrain and wondering how one did that
+in earlier times. Just like today scenery is not by definition better
+than yestedays, \MKIV\ code is not always better than \MKII\ code.

+\chapter {Token speak}
+
+\subject{tokenization}
+
+Most \TEX\ users only deal with (keyed in) characters and (produced) output. Some
+will play with boxes, skips and kerns or maybe even leaders (repeated sequences
+of the former). Others will be grateful that macro package writers take care of
+such things.
+
+Macro writers on the other hand deal properties of characters, like catcodes and
+a truckload of other codes, with lists made out of boxes, skips, kerns and
+penalties but even they cannot look much deeper into \TEX's internals. Their
+deeper understanding comes from reading the \TEX book or even looking at the
+source code.
+
+When someone enters the magic world of \TEX\ and starts asking around on a bit,
+he or she will at some point get confronted with the concept of \quote {tokens}.
+A token is what ends up in \TEX\ after characters have entered its machinery.
+Sometimes it even seems that one is only considered a qualified macro writer if
+one can talk the right token||speak. So what are those magic tokens and how can
+\LUATEX\ shed light on this.
+
+In a moment we will show examples of how \LUATEX\ turns characters into tokens,
+but when looking at those sequences, you need to keep a few things in mind:
+
+\startitemize[packed]
+\startitem
+    A sequence of characters that starts with an escape symbol (normally this is
+    the backslash) is looked up in the hash table (which relates those names to
+    meanings) and replaced by its reference. Such a reference is much faster than
+    looking up the sequence each time.
+\stopitem
+\startitem
+    Characters can have special meanings, for instance a dollar is often used to
+    enter and exit math mode, and a percent symbol starts a comment and hides
+    everything following it on the same line. These meanings are determined by
+    the character's catcode.
+\stopitem
+\startitem
+    All the characters that will end up actually typeset have catcode \quote
+    {letter} or \quote {other} assigned. A sequence of items with catcode
+    \quote{letter} is considered a word and can potentially become hyphenated.
+\stopitem
+\stopitemize
+
+\subject{examples}
+
+We will now provide a few examples of how \TEX\ sees your input.
+
+\starttyping
+Hi there!

+
+\starttokens[demo]Hi there!\stoptokens \setups{ShowCollect}
+
+Here we see three kind ot tokens. At this stage a space is still recognizable as
+such but later this will become a skip. In our current setup, the exclamation
+mark is not a letter.
+
+\starttyping
+Hans \& Taco use Lua\TeX \char 33\relax
+\stoptyping
+
+\starttokens[demo]Hans \& Taco use Lua\TeX \char 33\relax\stoptokens \setups{ShowCollect}
+
+Here we see a few new tokens, a \quote {char\_given} and a \quote {call}. The
+first represents a \type {\chardef} i.e.\ a reference to a character slot in a
+font, and the second one a macro that will expand to the \TEX\ logo. Watch how
+the space after a control sequence is eaten up. The exclamation mark is a direct
+reference to character slot~33.

+\noindent {\bf Hans} \par \hbox{Taco} \endgraf
+\stoptyping
+
+\starttokens[demo]\noindent {\bf Hans} \par \hbox{Taco} \endgraf\stoptokens \setups{ShowCollect}
+
+As you can see, some primitives and macro's that are bound to them (like \type
+{\endgraf}) have an internal representation on top of their name.

+As you can see, registers are not explicitly named, one needs the associated
+register code to determine it's character (a dimension in our case).
+
+\starttyping
+before \inframed[width=3cm]{whatever} after
+\stoptyping
+
+\starttokens[demo]before \inframed[width=3cm]{whatever} after\stoptokens \setups{ShowCollect}
+
+As you can see, even when control sequences are collapsed into a reference, we
+still end up with many tokens, and because each token has three properties (cmd,
+chr and id) in practice we end up with more memory used after tokenization.
+
+\starttyping
+compound|-|word
+\stoptyping
+
+\starttokens[demo]compound|-|word\stoptokens \setups{ShowCollect}
+
+This example uses an active character to handle compound words (a \CONTEXT\
+feature).
+
+\starttyping
+hm, \directlua 0 { tex.sprint("Hello World") }
+\stoptyping
+
+\starttokens[demo]hm, \directlua 0 { tex.sprint("Hello World!") }\stoptokens \setups{ShowCollect}
+
+The previous example shows what happens when we include a bit of \LUA\ code
+\unknown\ it is just seen as regular input, but when the string is passed to
+\LUA, only the chr property is passed, so we no longer can distinguish between
+letters and other characters.
+
+A macro definition converts to tokens as follows.
+
+\starttokens[demo]\def\Test#1#2{[#2][#1]} \Test{A}{B}\stoptokens \setups{ShowCollect}
+
+As we already mentioned, a token has three properties. More details can be found
+in the reference manual so we will not go into much detail here.
+
+{\bf The original interceptor for tokens but that one has been replaced by a more
+powerful scanning mechanism. The following text is no longer applicable but kept
+as historic reference. The new token scanner is discussed in later articles.}
+
+% keep text formatted as it is now:
+
+\starttyping[color=]
+
+A most simple callback is:
+
+\starttyping
+callback.register('token_filter', token.get_next)
+\stoptyping
+
+In principle you can call \type {token.get_next} anytime you want
+to intercept a token. In that case you can feed back tokens into
+\TEX\ by using a trick like:
+
+\starttyping
+function tex.printlist(data)
+   callback.register('token_filter', function ()
+       callback.register('token_filter', nil)
+       return data
+    end)
+end
+\stoptyping
+
+Another example of usage is:
+
+\starttyping
+callback.register('token_filter', function ()
+    local t = token.get_next
+    local cmd, chr, id = t[1], t[2], t[3]
+    -- do something with cmd, chr, id
+    return { cmd, chr, id }
+end)
+\stoptyping
+
+There is a whole repertoire of related functions, one is \type
+{token.create}, which can be used as:
+
+\starttyping
+tex.printlist{
+    token.create("hbox"),
+    token.create(utf.byte("{"),  1),
+    token.create(utf.byte("?"), 12),
+    token.create(utf.byte("}"),  2),
+}
+\stoptyping
+
+This results in: \ctxlua {
+    tex.printlist{
+        token.create("hbox"),
+        token.create(utf.byte("{"),  1),
+        token.create(utf.byte("?"), 12),
+        token.create(utf.byte("}"),  2),
+    }
+}
+
+While playing with this we made a few auxiliary functions that
+permit things like:
+
+\starttyping
+tex.printlist ( table.unnest ( {
+    tokens.hbox,
+    tokens.bgroup,
+    tokens.letters("12345"),
+    tokens.egroup,
+} ) )
+\stoptyping
+
+Unnesting is needed because the result of the \type {letters} call
+is a table, and the \type {printlist} function wants a flattened
+table.
+
+The result looks like: \ctxlua {
+    local t = table.unnest {
+        tokens.hbox,
+        tokens.bgroup,
+        tokens.letters("12345"),
+        tokens.egroup,
+    }
+    tex.printlist (t)
+    tokens.collectors.show(t)
+}
+
+In practice, manipulating tokens or constructing lists of tokens
+this way is rather cumbersome, but at least we now have some
+kind of access, if only for illustrative purposes.
+
+\starttyping
+\hbox{12345\hbox{54321}}
+\stoptyping
+
+can also be done by saying:
+
+\starttyping
+tex.sprint("\\hbox{12345\\hbox{54321}}")
+\stoptyping
+
+or under \CONTEXT's basic catcode regime:
+
+\starttyping
+tex.sprint(tex.ctxcatcodes, "\\hbox{12345\\hbox{54321}}")
+\stoptyping
+
+If you like it the hard way:
+
+\starttyping
+tex.printlist ( table.unnest ( {
+    tokens.hbox,
+        tokens.bgroup,
+            tokens.letters("12345"),
+            tokens.hbox,
+                tokens.bgroup,
+                    tokens.letters(string.reverse("12345")),
+                tokens.egroup,
+        tokens.egroup
+} ) )
+\stoptyping
+
+This method may attract those who dislike the traditional \TEX\
+syntax for doing the same thing. Okay, a careful reader will
+notice that reversing the string in \TEX\ takes a bit more
+trickery, so \unknown
+
+\stoptyping
+
+% end of verbose text
+
+{\bf The \type {tokens} etc.\ examples shows here make no sense anyway as we have
+a more extensive interface to the macro language: \type {context}.}

+\chapter{Tracking}
+
+We entered 2009 with a partial reimplementation of the \OPENTYPE\
+feature handler. One of the reasons was an upgrade of the
+\FONTFORGE\ libraries that \LUATEX\ uses.
+
+The specification of \OPENTYPE\ is kind of vague. Apart from a
+lack of a proper free specifications there's also the problem that
+Microsoft and Adobe may have their own interpretation of how and
+in what order to apply features. In general the Microsoft website
+has more detailed specifications and is a better reference. There
+is also some information in the \FONTFORGE\ help files.
+
+Because there is so much possible, fonts might contain bugs and/or
+be made to work with certain renderers. These may evolve over time
+which may have the side effect that suddenly fonts behave
+differently.
+
+After a lot of experiments (mostly by Taco, me and Idris) we're
+now at yet another implementation. Of course all errors are mine
+and of course the code can be improved. There are quite some
+optimization going on here and processing speed is currently
+acceptable. Not all functions are implemented yet, often because I
+lack the fonts for testing. Many scripts are not yet supported
+either, but I will look into them as soon as \CONTEXT\ users ask
+for it.
+
+The data provided by the \FONTFORGE\ library has organized lookups
+(which relate to features) in a certain way. A first
+implementation of this code was organized featurewise: information
+related to features was collected and processing boiled down to a
+run over the features. The current implementation honours the order
+in the main feature table. Since we can reorder this table as we
+want, we can eventually support several models of processing. We
+kept the static as well as dynamic feature processing, because it
+had proved to be rather useful. The formerly three loop variants
+have been discarded but might reappear at some time.
+
+One reason for this change is that the interactive version of
+\FONTFORGE\ now provides a more detailed overview of the way
+lookups are supposed to be handled. When you consult the
+information of a font and in particular a glyph in a font, you now
+get quite some information about what features can be applied and
+in what order this takes place.
+
+In \CONTEXT\ \MKIV\ we deal with this as follows. Keep in mind
+that we start with characters but stepwise these can become more
+abstract representation, named glyphs. For instance a letter~a can
+be represented by a shape (glyph) that is similar to an uppercase~A.
+
+\startitemize
+
+\item We loop over all lookups. Normally there are only a few
+lookups but fonts that deal with scripts that resemble
+handwriting, like arabic of Zapfino, might have hundreds of them.
+Each lookup has a detailed specification of what language and/or
+scripts it applies to.
+
+\item For each lookup we do a run over the list of glyphs. So, if
+we have 50 lookups, and a paragraph has 500 glyphs, we do some
+25000 loops. Keep in mind that for arab we start with a sequence
+of characters and vowels, and during a run, these might be
+replaced by for instance ligatures and combined vowels, so the 500
+stepwise becomes less.
+
+\item We only process the features that are enabled. Normally the
+lookups are organized in such a way that features take place in a
+similar way: (de)composition, replacement of initial, medial,
+final and isolated forms, specific replacements by one or more
+variant, composition of ligatures, mark positioning, cursive
+corrections and kerning. The font itself does not contain
+information about what features are to be enabled by default. Some
+applications have built in presets, others might extend their
+repertoire over time.
+
+\item A lookup can be a contextual lookup, which means that
+treatment takes place on a match of a sequence of characters
+(glyphs), either of not preceded or followed by specific other
+characters (glyphs). We we loop over all contexts till we have a
+match. Some fonts have lots of contextual lookups, which in turn
+might increase the number of loops over the list of characters
+(glyphs). If we have a match, we process the associated list of
+sublookups. Technically it is possible to replace (say) five
+characters by first a ligature (that replaces the first two by
+one), then a multiple substitution (resulting in an extra three
+glyphs replacing one) and then discarding the other rest (being
+two characters). Because by that time characters (say, unicode
+points) might have been replaced by glyphs (an index in the font)
+a contextual lookup can involve quite some match points.
+
+\stopitemize
+
+In \CONTEXT\ we do this for each font that is used in a list, so
+in practice we have quite some nested loops. Each font can have
+its own set of features enables of features might be applied
+dynamically, independent of font related settings. So, around the
+mentioned loops there is another one: a loop over the fonts used
+in a list (paragraph).
+
+We process the whole list and then consult the glyph nodes. An
+alternative approach is to collect strings of characters using the
+same font including spaces (because some lookups involve spaces).
+However, we then need to reconstruct the list which is no fun.
+Also, we need to carry quite some information, like attributes, so
+eventually we don't gain much (if we gain something at all).
+
+Another consideration has been to operate on sublists of font
+usage (using a subhead and subtail) but again this would
+complicate matters as we then neext to keep track of a changing
+subhead and subtail. On the other hand, this might save some
+runtime. The number of changes in the code needed to do this is
+not that large but it only makes sense when we have many fonts
+in a list and don't change fonts to frequently.
+
+This whole treatment is rather extensively optimized and so the
+process is reasonable fast (you really don't want to know how much
+time was spent on figuring out fast methods, testing and
+reimplementing this). While I was implementing the \LUA\ code,
+Taco made sure that access to the information in nodes was as fast
+as possible and in our usual chat sessions we compared the output
+with the one produced by the \FONTFORGE\ preview.
+
+It was for this reason that more and more debugging code was added
+but even that made tracking of what really happened cumbersome.
+Therefore a more visual method was written, which will be shown
+laster on.
+
+You can enable tracing using the designated commands:
+
+\starttyping
+\enabletracker[otf.ligatures,otf.singles]
+\stoptyping
+
+and disable them for instance with:
+
+\starttyping
+\disabletracker[otf.*]
+\stoptyping
+
+Or you can pass directives to the command line:
+
+\starttyping
+context --track=otf.ligatures myfile.tex
+\stoptyping
+
+With regards to \OPENTYPE\ handling we have the following tracker
+keys available:
+
+\starttabulate

+\stoptabulate
+
+We now show another way to track what happens with your text.
+Because this is rather verbose, you should only apply it to words.
+The second argument can be \type {-1} (right to left), \type {0}
+(default) or \type {1} (left to right). The third argument can
+be invisible in the code because the font used for verbatim might
+lack the shapes. A font has a different ordering than \UNICODE\
+because after all one character can have multiple
+representations, one shape can be used for multiple characters,
+or shapes might not have a \UNICODE\ point at all. In \MKIV\ we
+push all shapes that have no direct relationship with \UNICODE\ to
+the private area so that \TEX\ still sees them (hence the large
+numbers in the following examples).
+
+The next example uses Latin Modern. Here we apply the following
+features:
+
+\typebuffer[latin-default-features]
+
+\startbuffer
+\showotfcomposition
+  {name:lmroman12regular*latin-default at 24pt}
+  {0}
+  {flinke fietser}
+\stopbuffer
+
+\typebuffer \start \veryraggedright \getbuffer \stop
+
+The next example uses Arabtype. Here we apply the following features:
+
+\typebuffer[arabtype-default-features]
+
+\startbuffer
+\showotfcomposition
+  {arabtype*arabtype-default at 48pt}
+  {-1}
+  {الضَّرَّ}
+\stopbuffer
+
+\typebuffer \start \veryraggedright \getbuffer \stop
+
+\startbuffer
+\showotfcomposition
+  {arabtype*arabtype-default at 48pt}
+  {-1}
+  {لِلّٰهِ}
+\stopbuffer
+
+\typebuffer \start \veryraggedright \getbuffer \stop
+
+Another arabic example (after all, fonts that support arabic have
+lots of nice features) is the following. First we define a bunch
+of feature collections
+
+\startbuffer
+\definefontfeature
+  [salt-n]
+  [analyze=yes,mode=node,
+   language=dflt,script=arab,
+   init=yes,medi=yes,fina=yes,isol=yes,
+   liga=yes,calt=yes,ccmp=yes,
+   kern=yes,curs=yes,mark=yes,mkmk=yes]
+
+\definefontfeature[salt-y][salt-n][salt=yes]
+\definefontfeature[salt-1][salt-n][salt=1]
+\definefontfeature[salt-2][salt-n][salt=2]
+\definefontfeature[salt-3][salt-n][salt=3]
+\definefontfeature[salt-r][salt-n][salt=random]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Next we show a few traced examples. Watch the reported alternatives.
+
+\startbuffer
+\showotfcomposition{scheherazaderegot*salt-n at 36pt}{-1}{\char"6DD}
+\showotfcomposition{scheherazaderegot*salt-y at 36pt}{-1}{\char"6DD}

+\showotfcomposition{scheherazaderegot*salt-r at 36pt}{-1}{\char"6DD}
+\showotfcomposition{scheherazaderegot*salt-r at 36pt}{-1}{\char"6DD}
+\stopbuffer
+
+\typebuffer \start \veryraggedright \getbuffer \stop
+
+The font that we use here can be downloaded from the website of
+Sil International.
+
+For a Zapfino example we use the following feature set:
+
+\typebuffer[zapfino-default-features]
+
+\startbuffer
+\showotfcomposition
+  {zapfinoextraltpro*zapfino-default at 48pt}
+  {0}
+  {Prof. Dr. Donald E. Knuth}
+\stopbuffer
+
+\typebuffer \start \veryraggedright \getbuffer \stop
+
+When dealing with features, we may run into problems due to
+characters that are in the input stream but have no associated
+glyph in the font. Although we test for this a user might want to
+intercept side effect.
+
+\starttyping
+\checkcharactersinfont
+\removemissingcharacters
+\stoptyping
+
+The first command only checks and reports missing characters,
+while the second one also removes them.

+\chapter{XML revisioned}
+
+{\em The code dealing with \XML\ is evolving and the following
+text might be outdated. So, in case of doubt, check the manual.}
+
+\subject{the parser}
+
+For quite a while \CONTEXT\ has built-in support for \XML\ processing and
+at \PRAGMA\ we use this extensively. One of the first things I tried to deal
+with in \LUA\ was \XML, and now that we have \LUATEX\ up and running it's
+time to investigate this a bit more. First we'll have a look at the basic
+functions, the \LUA\ side of the game.
+
+We load an \XML\ file as follows (the \type {document} namespace
+is predefined in \CONTEXT):
+
+\startbuffer
+\startluacode
+    document.xml = document.xml or { } -- define namespace
+    document.xml = xml.load("mk-xml.xml") -- load the file
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The loader constructs a table representing the document structure, including
+whitespace, so let's serialize the code and see what shows up:
+
+\startbuffer
+\startluacode
+    local prn = xml.newhandlers { handle = tex.sprint }
+    tex.sprint("\\starttyping")
+    xml.serialize(document.xml, prn)
+    tex.sprint("\\stoptyping")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+In the first version of the serializer, we could pass extra function
+arguments that controlled the way content was processed. This method
+has now been replaced by handlers. In this example we create a
+simple handler where the \type {handle} function is responsible
+for the final print.
+
+\getbuffer
+
+This already gives us a rather basic way to manipulate documents and
+this method is even not that slow because we bypass \TEX\ reading from
+file.
+
+\startbuffer
+\startluacode
+    local str = "<l> <w>hello</w> <w>world</w> </l>"
+    local prn = xml.newhandlers { handle = tex.sprint }
+    tex.sprint("\\starttyping")
+    xml.serialize(xml.convert(str),prn)
+    tex.sprint("\\stoptyping")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Watch the extra print argument, we need this because otherwise the
+verbatim mode will not work out well.
+
+\getbuffer
+
+You need to keep in mind that in these examples we print to \TEX\ under
+the current catcode regime.
+
+You can save a \XML\ table with the command:
+
+\starttyping
+\startluacode
+    xml.save(document.xml,"newfile.xml")
+\stopluacode
+\stoptyping
+
+These examples show that you have access to \XML\ files from
+within your document. If you want to convert the table to just a
+string, you can use \type {xml.tostring}. Actually, this method is
+automatically used for occasions where \LUA\ wants to print an
+\XML\ table or wants to join string snippets. However, as we are
+inside \TEX, we need to print to \TEX\ instead of the console or
+file. For this we use specialized handlers.
+
+The reason why I wrote the \XML\ parser is that we need it in the
+utilities (so it has to provide access to the content of elements)
+as well as in the text processing (so it needs to provide some
+manipulation features). To serve both we have implemented a subset
+of what standard \XML\ tools qualify as path based searching.
+
+\startbuffer
+\startluacode
+    xml.sprint(xml.first(document.xml, "/one/three/some"))
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+The result of this snippet is the content of the first element
+that matches the specification: \quote{\getbuffer}. As you can
+see, this comes out rather verbose. The reason for this is that we
+need to enter \XML\ mode in order to get such a snippet
+interpreted.
+
+Below we give a few more variants, this time
+we use a generic filter:
+
+\startbuffer
+\startluacode
+    xml.sprint(xml.filter(document.xml, "/one/three/some"))
+\stopluacode
+\stopbuffer
+
+\typebuffer result: \astype{\getbuffer}
+
+\startbuffer
+\startluacode
+    xml.sprint(xml.filter(document.xml, "/one/three/some/first()"))
+\stopluacode
+\stopbuffer
+
+\typebuffer result: \astype{\getbuffer}
+
+\startbuffer
+\startluacode
+    xml.sprint(xml.filter(document.xml, "/one/three/some[1]"))
+\stopluacode
+\stopbuffer
+
+\typebuffer result: \astype{\getbuffer}
+
+\startbuffer
+\startluacode
+    xml.sprint(xml.filter(document.xml, "/one/three/some[-1]"))
+\stopluacode
+\stopbuffer
+

+
+The next lines shows some more variants. There are more than these and
+we will extend the repertoire over time. If needed you can define
+additional handlers.
+
+\subject{performance}
+
+Before we continue with more examples, a few remarks about the
+performance. The first version of the parser was an enhanced
+version of the one presented in the \LUA\ book: support for
+namespaces, processing instructions, comments, cdata and doctype,
+remapping and a few more things. When playing with the parser I
+was quite satisfied about the performance. However, when I started
+experimenting with 40~megabyte files, the preprocessing (needed
+for the special elements) started to become more noticeable. For
+smaller files its 40\% overhead is not that disturbing, but for
+large files \unknown\
+
+The current version uses \LPEG. We follow the same approach as
+before, stack and top and such but this time parsing is about
+twice as fast which is mostly due to the fact that we don't have
+to prepare the stream for cdata, doctype etc. Loading the
+mentioned large file took 12.5 seconds (1.5 for file io and the
+rest for tree building) on my laptop (a 2.3 Ghz Core Duo running
+Windows Vista). With the \LPEG\ implementation we got that down to
+less 7.3 seconds. Loading the 14 interface definition files (2.6
+meg) went down from 1.05 seconds to 0.55 seconds. Namespace
+related issues take some 10\% of this.
+
+Of course these numbers might change over time. For instance, we
+now have the second implementation of the filter mechanism which
+is more advanced and maybe somewhat slower on some tasks.
+
+\subject{patterns}
+
+We will not implement complete \XPATH\ functionality, but only the
+features that make sense for documents that are well structured
+and needs to be typeset. In addition we (will) implement text
+manipulation functions. Of course speed is also a consideration
+when implementing such mechanisms.
+
+The following list is not complete (after all here we only give an
+impression of the development) but it gives a good impression.

+\stoptabulate
+
+This list shows that it is also possible to ask for more matches at
+once. Namespaces are supported (including a wildcard) and there are
+mechanisms for namespace remapping.
+
+\startbuffer
+\startluacode
+    lxml.concat(document.xml,"/one/(three|five)/some",", "," and ")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We get: \astype{\getbuffer} and if we say:
+
+\startbuffer
+\startluacode
+    lxml.concat(document.xml,"/one/(three|five)/some",", "," and ",
+        true)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We get: \quote {\getbuffer}.
+
+Watch how we use the \type {lxml} namespace here! Here live the
+functions that pipe the result to \TEX.
+
+\startbuffer
+\startluacode
+    lxml.count(document.xml,"/one/(three|five)/some")
+\stopluacode
+\stopbuffer
+
+There a several helper functions, like \type {xml.count} which in this case
+returns~\getbuffer.
+
+\typebuffer
+
+Functions like this gives the opportunity to loop over lists of elements
+by index.
+
+\subject{manipulations}
+
+We can manipulate elements too. The next code will add some elements
+at specific locations.
+
+\startbuffer
+\startluacode
+    xml.before(document.xml,"xml:///one/three/some","<be>ok</be>")
+    xml.after (document.xml,"xml:///one/three/some","<af>ok</af>")
+    tex.sprint("\\starttyping")
+    xml.sprint(lxml.filter(document.xml,"/one/three"))
+    tex.sprint("\\stoptyping")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+And indeed, we suddenly have a couple of \quote {ok}'s there:
+
+\getbuffer
+
+Of course wel can also delete elements:
+
+\startbuffer
+\startluacode
+    xml.delete(document.xml,"/one/three/some")
+    xml.delete(document.xml,"/one/three/af")
+    tex.sprint("\\starttyping")
+    xml.sprint(lxml.filter(document.xml,"/one/three"))
+    tex.sprint("\\stoptyping")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Now we have:
+
+\getbuffer
+
+Replacing an element is also possible. The replacement can be a
+table (representing elements) or a string which is then converted
+into a table first.
+
+\startbuffer
+\startluacode
+    xml.replace(document.xml,"/one/three/be","<mid>done</mid>")
+    tex.sprint("\\starttyping")
+    xml.sprint(lxml.filter(document.xml,"/one/three"))
+    tex.sprint("\\stoptyping")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+And indeed we get:
+
+\getbuffer
+
+These are just a few features of the library. I will add some more (rather) generic
+manipulaters and extend the functionality of the existing ones. Also, there will
+be a few manipulation functions that come in handy when preparing texts for
+processing with \TEX\ (most of the \XML\ that I deal with is rather dirty and needs
+some cleanup).
+
+\subject{streaming trees}
+
+Eventually we will provies series of convenient macros that will provide an
+alternative for most of the \MKII\ code. In \MKII\ we have a streaming parser, which
+boils down to attaching macros to elements. This includes a mechanism for saving
+an restoring data, but this is not always convenient because one also has to
+intercept elements that needs to be hidden.
+
+In \MKIV\ we do things different. First we load the complete document in memory (a
+\LUA\ table). Then we flush the elements that we want to process. We can associate
+setups with elements using the filters mentioned before. We can either use \TEX\ or
+use \LUA\ to manipulate content. Instead if a streaming parser we now have a mixture
+of streaming and tree manipulation available. Interesting is that the \XML\ loader
+is pretty fast and piping data to \TEX\ is also efficient. Since we no longer need to
+manipulate the elements in \TEX\ we gain processing time too, so in practice we have
+now much faster \XML\ processing available.
+
+To give you an idea we show a few commands:
+
+\startbuffer
+\xmlload {main}{mk-xml.xml}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+So that we can do things like (there are and will be a few more):
+
+\starttabulate[|l|l|l|]
+\NC \bf command        \NC \bf arguments                        \NC \bf result                          \NC \NR
+\NC \type {\xmlfirst}  \NC \type {{main} {/one/three/some}}     \NC \xmlfirst{main}{/one/three/some}    \NC \NR
+\NC \type {\xmllast }  \NC \type {{main} {/one/three/some}}     \NC \xmllast {main}{/one/three/some}    \NC \NR
+\NC \type {\xmlindex}  \NC \type {{main} {/one/three/some} {2}} \NC \xmlindex{main}{/one/three/some}{2} \NC \NR
+\stoptabulate
+
+There is a set of about 30 commands that operates on the tree: loading, flushing,
+filtering, associating setups and code in modules to elements. For instance when
+one uses so called cals||tables, the processing is automatically activates when the
+namespace can be resolved. Processing is collected in setups and those registered
+are these are processed after loading the tree. In the following example we register
+a handler for content that needs to end up bold.
+
+\starttyping
+\startxmlsetups xml:mysetups
+    \xmlsetsetup{\xmldocument}{bold|bf}{xml:handlebold}
+\stopxmlsetups
+
+\xmlregistersetup{xml:mysetups}
+
+\startxmlsetups xml:handlebold
+    \dontleavehmode
+    \bgroup
+    \bf
+    \xmlflush{#1}
+    \egroup
+\stopxmlsetups
+\stoptyping
+
+In this example \type {#1} represents the root of the subtree. Say that we
+want to process an index entry which is coded as follows:
+
+\starttyping
+<index>
+    <entry>whatever</entry>
+    <key>whatever</key>
+</index>
+\stoptyping
+
+We register an additional handler (here the \type {*} is a shortcut for
+using the element's tag as setup name):
+
+\starttyping
+\startxmlsetups xml:mysetups
+    \xmlsetsetup{\xmldocument}{bold|bf}{xml:handlebold}
+    \xmlsetsetup{\xmldocument}{index}{*}
+\stopxmlsetups
+
+\xmlregistersetup{xml:mysetups}
+
+\startxmlsetups index
+    \index[\xmlfirst{#1}{key}]{\xmlfirst{#1}{entry}}
+\stopxmlsetups
+\stoptyping
+
+In practice \MKIV\ definitions are more compact than the comparable
+\MKII\ ones, especially for more complex constructs (tables and such).
+
+\starttyping
+\defineXMLenvironment
+  [index]
+  {\bgroup
+   \defineXMLsave[key]%
+   \defineXMLsave[entry]}
+  {\index[\XMLflush{key}]{\XMLflush{entry}}%
+   \egroup}
+\stoptyping
+
+This looks compact, but keep in mind that we also need to get rid of
+spurry spaces and when the code grows, we usually use setups to separate
+the definition from the code. In any case, the \MKII\ solution involves
+a few definitions as well as saving the content of elements. This is often
+much more costly than the \MKIV\ method where we only locate and flush
+content. Of course the document is stored in memory, but that happens
+pretty fast: storing the 14~files (2~per interface) that define the \CONTEXT\
+user interface takes .85 seconds on a 2.3 Ghz Core Duo (Windows Vista) which
+is not that bad if you take into account that we're talking of 2.7 megabytes
+of highly structured data (many elements and attributes, not that much text).
+Loading one of these files using \MKII\ code (for storing elements) takes
+many more seconds.
+
+I didn't do extensive speed tests yet but for normal streamed
+processing of simple documents the penalty of loading the tree can be
+neglected. When comparing traditional \MKII\ code like:
+
+\starttyping
+\defineXMLargument   [title][id=] {\subject[\XMLop{at}]}
+\defineXMLenvironment[p]          {} {\par}
+
+\starttext
+    \processXMLfilegrouped{testspeed.xml}
+\stoptext
+\stoptyping
+
+with its \MKIV\ counterpart:
+
+\starttyping
+\startxmlsetups document
+    \xmlsetsetup\xmldocument{title|p}{*}
+\stopxmlsetups
+
+\xmlregistersetup{document}
+
+\startxmlsetups title
+    \section[\xmlatt{#1}{id}]{\xmlcontent{#1}{/}}
+\stopxmlsetups
+
+\startxmlsetups p
+    \xmlflush{#1}\endgraf
+\stopxmlsetups
+
+\starttext
+    \processXMLfilegrouped{testspeed.xml}
+\stoptext
+
+I found that processing a one megabyte file with some 400 sections
+takes the same runtime for both approaches. However, as soon as more
+complex manipulations enter the game the \MKIV\ method starts taking
+less time. Think of the manipulations needed for \MATHML\ or converting
+tables into something that \CONTEXT\ can handle. Also, when we deal
+with documents where we need to ignore large portions of shuffle content
+around, the traditional method also has to store data in memory and in
+that case \MKII\ code always loses from \MKIV\ code. Of course any speed
+we gain in handling \XML\ is lost on processing complex fonts and
+attributes but there we gain in quality.
+
+\stoptyping
+
+Another advantage of the \MKIV\ mechanisms is that we suddenly have so called
+fully expandable \XML\ handling. All manipulations take place in \LUA\ and
+there is no interfering code at the \TEX\ end.
+
+\subject{examples}
+
+For the path freaks we now show what patterns lead to. For this we will
+use the following \XML\ data:
+
+\startbuffer[xml]
+<?xml version='1.0' ?>
+<a>
+    <?what is this?>
+    <b>
+        <c n='x'>c1</c><d>d1</d>
+    </b>
+    <b>
+        <c n='y'>c2</c><d>d2</d>
+    </b>
+    <?what is that?>
+    <c><d>d3</d></c>
+    <c n='y'><d>d4</d></c>
+    <c><d>d5</d></c>
+</a>
+\stopbuffer
+
+\typebuffer[xml]
+
+\xmlloadbuffer{xml}{xml}
+
+\startluacode
+    function document.ShowResultOfPattern(root,pattern)
+        local ok = false
+        for r,d,k in xml.elements(lxml.id(root),pattern) do
+            tex.print(xml.tostring(d[k]))
+            tex.sprint(tex.ctxcatcodes,"\\par")
+            ok = true
+        end
+        if not ok then
+            tex.sprint("no match")
+            tex.sprint(tex.ctxcatcodes,"\\par")
+        end
+    end
+\stopluacode

+
+{\it The actual form of the tables shown here might have changed
+in the meantime. However, since this document describes the
+stepwise development of \LUATEX\ and \CONTEXT\ \MKIV\ we don't
+update the following information. The rendering might differ from
+earlier rendering simply because the code used to process this
+chapter evolves.}
+
+\subject {features}
+
+In previous chapters we've seen support for \OPENTYPE\ features creep into \LUATEX\ and
+\CONTEXT\ \MKIV. However, it may not have been clear that so far we were just feeding
+the traditional \TEX\ machinery with the right data: ligatures and kerns. Here we will
+show what so called features can do for you. Not much \LUA\ code will be shown, if
+only because relatively complex code is needed to handle this kind of trickery with
+acceptable performance.
+
+In order to support features in their full glory more is needed than \TEX's ligature
+and kern mechanisms: we need to manipulate the node list. As a result, we have now a
+second mechanism built into \MKIV\ and users can choose what method they like most. The
+first method, called \type {base}, is less powerful and less complete
+than the one named \type {node}. Eventually \CONTEXT\ will use the node method by
+default.
+
+There are two variants of features: substitutions and positioning. Here we
+concentrate on substitutions of which there are several. Positioning is for instance
+used for specialized kerning as needed in for instance typesetting Arab.
+
+One character representation can be replaced by one or more fixed alternatives or alternatives
+chosen from a list of alternatives (substitutions or alternates). Multiple characters
+can be replaces by one character (substitutions, alternates or a ligature). The
+replacements can depend on preceding and|/|or following glyphs in which case we say that
+the replacement is driven by rules. Rules can deal with single glyphs, combinations of
+glyphs, classes (defined in the font) of glyphs and|/|or ranges of  glyphs.
+
+Because the available documentation of \OPENTYPE\ is rather minimalistic and because
+most fonts are relatively simple, you can imagine that figuring out how to
+implement support for fonts with advanced features is not entirely trivial
+and involves some trial and error. What also complicate things is that features can
+interfere. Yet another complicating factor is that in the order of applying a rule may
+obscure a later rule. Such fonts don't ship with manuals and examples of correct output
+are not part of the buy.
+
+We like testing \LUATEX's open type support with Palatino Regular and Palatino Sans and
+good old \TYPEONE\ support with Optima Nova. So it makes sense to test advanced
+features with Zapfino Pro. This font has many features, which happen to be
+implemented by Adam Twardoch, a well known font expert and familiar with the \TEX\
+community. We had the feeling that when \LUATEX\ can support Zapfino Pro, designed by
+Hermann Zapf and enhanced by Adam, we have reached a crucial point in the development.
+
+The first thing that you will observe when using this font is that the files are larger
+than normal, especially the cached versions in \MKIV. This made me extend some of the
+serialization code that we use for caching font data so that it could handle huge
+tables better but at the cost of some speed. Once we could handle the data conveniently
+and as a side effect look into the font data with an editor, it became clear that
+implementing for the \type {calt} and \type {clig} features would take a bit
+of coding.
+
+\subject{example}
+
+Before some details will be discussed, we will show two of the test texts that \CONTEXT\
+users normally use when testing layouts or new features, a quote from E.R.\ Tufte and
+one from Hermann Zapf. The \TEX\ code shows how features are set in \CONTEXT.

+
+\subject{obeying rules}
+
+When we were testing node based feature support, the only way to check this was to
+identify the rules that lead to certain glyphs. The more unique glyphs are good
+candidates for this. For instance
+
+\startitemize[packed]
+\item there is s special glyph representing \SampleChar{c_slash_o}
+\item in the input stream this is the character sequence \type{c/o}
+\item so there most be a rule that tells us that this sequence becomes that ligature
+\stopitemize
+
+As said, in this case, the replacement glyph is supposed to be a ligature and indeed
+there is such a ligature: \type {c_slash_o}. Of course, this replacement will only
+take place when the sequence is surrounded by spaces.
+
+However, when testing this, we were not looking at this rule but at the (randomly
+chosen) rule that was meant to intercept the alternative \type {h.2} followed
+by \type {z.4}. Interesting was that this resolved to a ligature indeed, but
+the shape associated with this ligature was an~\type {h}, which is not right.
+Actually, a few more of such rules turned out to be wrong. It took a bit of
+an effort to reach this conclusion because of the mentioned interferences
+of features and rules. At that time, the rule entry (in raw \LUATEX\ table
+format) looks as follows:
+
+\starttyping
+[44] = {
+    ["format"] = "coverage",
+    ["rules"] = {
+        [1] = {
+            ["coverage"] = {
+                ["ncovers"] = {
+                    [1] = "h.2",
+                    [2] = "z.4",
+                }
+            },
+            ["lookups"] = {
+                [1] = {
+                    ["lookup_tag"] = "L084",
+                    ["seq"] = 0,
+                }
+            }
+        }
+    }
+    ["script_lang_index"] = 1,
+    ["tag"] = "calt",
+    ["type"] = "chainsub"
+}
+\stoptyping
+
+Instead of reinventing the wheel, we used the \FONTFORGE\ libraries for reading the
+\OPENTYPE\ font files. Therefore the \LUATEX\ table is resembling the internal \FONTFORGE\
+data structures. Currently we show the version~1 format.
+
+Here \type {ncovers} means that when the current character has shape \SampleChar
+{h.2} (\type{h.2}) and the next one is \SampleChar{z.4} (\type{z.4}) (a sequence)
+then we need to apply the lookup internally tagged \type {L084}. Such a rule
+can be more extensive, for instance instead of \type {h.2} one can have a list of
+characters, and there can be \type {bcovers} and \type {fcovers} as well, which means
+that preceding or following character need to be taken into account.
+
+When this rule matches, it resolves to a specification like:
+
+\starttyping
+[6] = {
+    ["flags"] = 0,
+    ["lig"] = {
+        ["char"] = "h",
+        ["components"] = "h.2 z.4",
+    },
+    ["script_lang_index"] = 65535,
+    ["tag"] = "L084",
+    ["type"] = "ligature",
+}
+\stoptyping
+
+Here \type {tag} and \type {script_lang_index} are kind of special and
+are part of an private feature system, i.e.\ they make up the cross reference
+between rules and glyphs. Watch how the components don't match the character,
+which is even more peculiar when we realize that these are the initials of the
+author of the font. It took a couple of Skype sessions and mails before
+we came to the conclusion that this was probably a glitch in the font. So,
+what to do when a font has bugs like this? Should one disable the feature?
+That would be a pitty because a font like Zapfino depends on it. On the other
+hand, given the number of rules and given the fact that there are different
+rule sets for some languages, you can imagine that making up the rules and
+checking them is not trivial.
+
+We should realize that Zapfino is an extraordinary case, because it used
+the \OPENTYPE\ features extensively. We can also be sure that the problems will
+be fixed once they are known, if only because Adam Twardoch (who did the job)
+has exceptionally high standards but it may take a while before the fix reached
+the user (who then has to update his or her font). As said, it also takes some
+effort to run into the situation described here so the likelihood of running
+into this rule is small. This also brings to our attention the fact that fonts
+can now contain bugs and updating them makes sense but can break existing
+documents. Since such fonts are copyrighted and not available on line, font
+vendors need to find ways to communicate these fixes to their customers.
+
+Can we add some additional checks for problems like this? For a while I
+thought that it was possible by assuming that ligatures have names like
+\type {h.2_z.4} but alas, sequences of glyphs are mapped onto ligatures
+using mappings like the following:
+
+\starttabulate[||||]
+\NC \type{three fraction four.2} \NC \type{threequarters} \NC \SampleChar{threequarters} \NC\NR
+\NC \type{three fraction four}   \NC \type{threequarters} \NC \SampleChar{threequarters} \NC\NR
+\NC \type{d r}                   \NC \type{d_r}           \NC \SampleChar{d_r}           \NC\NR
+\NC \type{e period}              \NC \type{e_period}      \NC \SampleChar{e_period}      \NC\NR
+\NC \type{f i}                   \NC \type{fi}            \NC \SampleChar{fi}            \NC\NR
+\NC \type{f l}                   \NC \type{fl}            \NC \SampleChar{fl}            \NC\NR
+\NC \type{f f i}                 \NC \type{f_f_i}         \NC \SampleChar{f_f_i}         \NC\NR
+\NC \type{f t}                   \NC \type{f_t}           \NC \SampleChar{f_t}           \NC\NR
+\stoptabulate
+
+Some ligature have no \type {_} in their names and there are also some
+inconsistencies, compare the \type {fl} and \type {f_f_i}. Here font
+history is painfully reflected in inconsistency and no solution can be
+found here.
+
+So, in order to get rid of this problem, \MKIV\ implements a method to ignore
+certain rules but then, this only makes sense if one knows how the rules
+are tagged internally. So, in practice this is no solution. However, you can
+imagine that at some point \CONTEXT\ ships with a database of fixes that
+are applied to known fonts with certain version numbers.
+
+We also found out that the font table that we used was not good enough for our
+purpose because the exact order in what rules have to be applies was not
+available. Then we noticed that in the meantime \FONTFORGE\ had moved on
+to version~2 and after consulting the author we quickly came to the conclusion
+that it made sense to use the updated representation.
+
+In version~2 the snippet with the previously mentioned rule looks as follows:
+
+\starttyping
+["ks_latn_l_66_c_19"]={
+ ["format"]="coverage",
+ ["rules"]={
+  [1]={
+   ["coverage"]={
+    ["current"]={
+     [1]="h.2",
+     [2]="z.4",
+    }
+   },
+   ["lookups"]={
+    [1]={
+     ["lookup"]="ls_l_84",
+     ["seq"]=0,
+    }
+   }
+  }
+ },
+ ["type"]="chainsub",
+},
+\stoptyping
+
+The main rule table is now indexed by name which is possible because the order
+of rules is specified somewhere else. The key \type {ncovers} has been replaced
+by \type {current}. As long as \LUATEX\ is in beta stage, we have the freedom to
+change such labels as some of them are rather \FONTFORGE\ specific.
+
+This rule is mentioned in a feature specification table. Here specific features are
+associated with languages and scripts. This is just one of the entries concerning
+\type {calt}. You can imagine that it took a while to figure out how best to
+deal with this, but eventually the \MKIV\ code could do the trick. The cryptic
+names are replacements for pointers in the \FONTFORGE\ datastructure. In order to be
+able to use \FONTFORGE\ for font development and analysis, the decision was made to
+stick closely to its idiom.
+
+\starttyping

+  ...
+  [67]={
+   ["features"]={
+    [1]={
+     ["scripts"]={

+
+\subject{practice}
+
+The few snapshots of the font table probably don't make much sense if you
+haven't seen the whole table. Well, it certainly helps to see the whole picture,
+but we're talking of a 14 MB file (1.5 MB bytecode). When resolving ligatures,
+we can follow a straightforward approach:
+
+\startitemize[packed]
+\item walk over the nodelist and at each character (glyph node) call a function
+\item this function inspects the character and takes a look at the following ones
+\item when a ligature is identified, the sequence of nodes is replaced
+\stopitemize
+
+Substitutions are not much different but there we look at just one character.
+However, contextual substitutions (and ligatures) are more complex. Here we need
+to loop over a list of rules (dependent on script and language) and this involves
+a sequence as well as preceding and following characters. When we have a hit, the
+sequence will be replaced by another one, determined by a lookup in the character
+table. Since this is a rather time consuming operation, especially because many
+surrounding characters need to be taken into account, you can imagine that we need
+a bit of trickery to get an acceptable performance. Fortunately \LUA\ is pretty fast
+when it comes down to manipulating strings and tables, so we can prepare some handy
+datastructures in advance.
+
+When testing the implementation of features one need to be aware of the fact that
+some appearance are also implemented using the regular ligature mechanisms. Take the
+following definitions:
+

+
+Here are Adam's recommendations with regards to the \type {dlig} feature:
+\quotation {The \type{dlig} feature is supposed to by use only upon user's
+discretion, usually on single runs, words or even pairs. It makes little
+sense to enable \type {dlig} for an entire sentence or paragraph. That's
+how the \OPENTYPE\ specification envisions it.}
+
+When testing features it helps to use words that look similar so next we will
+show some examples that used. When we look at these examples, we need to
+understand that when a specific character representation is analyzed, the
+rules can take preceding and following characters into account. The rules
+take characters as well as their shapes, or more precisely: one of their
+shapes since Zapfino has many variants, into account. Since different rules
+are used for languages (okay, this is limited to only a subset of languages
+that use the latin script) not only shapes but also the way words are
+constructed are taken into account. Designing te rules is definitely non trivial.
+
+When testing the implementation we ran into cases where the initial \type
+{t} showed up wrong, for instance in the the Dutch word \type {troef}.
+Because space can be part of the rules, we need to handle the
+cases where words end and start and boxes are then kind of special.

+\startsubject[title=Introduction]
+
+This manual describes just one type of rules: those that somehow magically are
+bound to the typeset text. We will mention a few mechanisms that relate to this
+in the sense that they share some of the underlaying code and logic. The term
+\quotation {rules} should be interpreted liberally as we can kick in some
+\METAPOST\ which then can get us away from straight rules.
+
+This manual will not be that extensive, after all these mechanisms are not that
+complex to configure.
+
+\stopsubject
+
+\startsubject[title=Underlining and overstriking]
+
+Already in \CONTEXT\ \MKII\ we had underlining available but with some
+limitations. We could handle more than one word but at some point you hit the
+limits of the engine. The \MKIV\ implementation is more flexible. In fact you can
+underline a whole document (which was actually a request from a user). This
+feature was also used by a collegue who was experimenting with texts for
+dyslectic readers.
+
+This mechanism is generic in the sense that a framework is provided to define
+rules that run alongside text. Take this:
+
+\setupbars[foregroundcolor=darkyellow,color=darkred]
+
+\startbuffer
+\underbars {drawing \underbar{bars} under words is a typewriter leftover}
+\overstrikes {striking words makes them \overstrike {unreadable} but
+sometimes even \overbar {top lines} come into view.}
+\stopbuffer
+
+\typebuffer
+
+This shows up as:
+
+\getbuffer
+
+We can best explain what happens by looking at how these commands are
+defined:
+
+\starttyping
+\definebar[overbar]   [method=1,dy=0.4, offset=1.8, continue=yes]
+\definebar[underbar]  [method=1,dy=-0.4,offset=-0.3,continue=yes]
+\definebar[overstrike][method=0,dy=0.4, offset=0.5, continue=yes]
+
+\definebar
+  [understrike]
+  [method=0,
+   offset=1.375,
+   rulethickness=2.5,
+   continue=yes,
+   order=background]
+
+\definebar[overbars]    [overbar]    [continue=no]
+\definebar[underbars]   [underbar]   [continue=no]
+\definebar[overstrikes] [overstrike] [continue=no]
+\definebar[understrikes][understrike][continue=no]
+\stoptyping
+
+The formal definitions of the commands are show in \definition [definebar, setupbar].
+
+\showdefinition{definebar}
+\showdefinition{setupbar}
+
+The \type {dy} parameter specifies the shift up or down. The offset defines how
+nested bars are shifted. The \type {method} determines centering of the bar: we
+set it to zero when we want an overstrike. The \type {continue} parameter is
+responsible for drawing over spaces and the \type {order} determines the layering.
+
+The units are either hard coded values like points or relate to the font at the spot
+of the bar. Here are some examples:
+
+\startbuffer
+\setupbars[unit=mm,rulethickness=1]     bar \underbar{foo} bar\quad
+\setupbars[unit=ex,rulethickness=1]     bar \underbar{foo} bar\quad
+\setupbars[unit=pt,rulethickness=1]     bar \underbar{foo} bar\quad
+\setupbars[unit=pt,rulethickness=10pt]  bar \underbar{foo} bar
+\stopbuffer
+
+\typebuffer \blank \start \getbuffer \stop \blank
+
+As if underlining wasn't already bad enough, of course at some point there came a
+request for dashed lines.
+
+\startbuffer
+test \underrandoms{test me} and \underrandom{test} or \underrandom{grep}
+test \underdashes {test me} and \underdash  {test} or \underdash  {grep}
+test \underdots   {test me} and \underdot   {test} or \underdot   {grep}
+\stopbuffer
+
+\typebuffer
+
+The above variants are predefined and render as:
+
+\startlines
+\tfb \getbuffer
+\stoplines
+
+A graphic is defined as follows. It boils down to drawing one or more shapes. In
+this example we also force a specific boundingbox so that the result gets
+positioned right.
+
+\starttyping
+\startuseMPgraphic{rules:under:...}
+    draw
+        ((0,RuleDepth) -- (RuleWidth,RuleDepth))
+        shifted (0,RuleFactor*RuleOffset)
+        withpen pencircle scaled RuleThickness
+        withcolor RuleColor ;
+    setbounds currentpicture to unitsquare xysized(RuleWidth,RuleHeight) ;
+\stopuseMPgraphic
+\stoptyping
+
+The following variables are available:
+
+\starttabulate[|T|||]
+\BC variable      \BC type     \BC meaning                                 \NC \NR
+\ML
+\NC RuleDirection \NC string   \NC the direction of the line               \NC \NR
+\NC RuleOption    \NC string   \NC whatever the caller finds useful        \NC \NR
+\NC RuleWidth     \NC number   \NC the requested width of the rule         \NC \NR
+\NC RuleHeight    \NC number   \NC the requested height of the rule        \NC \NR
+\NC RuleDepth     \NC number   \NC the requested depth of the rule         \NC \NR
+\NC RuleThickness \NC number   \NC the linewidth                           \NC \NR
+\NC RuleFactor    \NC number   \NC the set factor (e.g. an \type {ex})     \NC \NR
+\NC RuleOffset    \NC number   \NC an (optional) offset in case of nesting \NC \NR
+\NC RuleColor     \NC color    \NC the color                               \NC \NR
+\stoptabulate
+
+The \type {RuleFactor} can be used as multiplier for the \type {RuleOffset}.
+Later we will see an example of how to use the \type {RuleDirection} and \type
+{RuleOption}.
+
+The extra under commands are defined as follows. Watch the \type {mp} parameter:
+it refers to a graphic.
+
+\starttyping
+\definebar
+  [undergraphic]
+  [mp=rules:under:dash,
+   offset=-.2,
+   order=background]
+
+\definebar[underrandom] [undergraphic][mp=rules:under:random]
+\definebar[underrandoms][underrandom] [continue=yes]
+
+\definebar[underdash]   [undergraphic][mp=rules:under:dash]
+\definebar[underdashes] [underdash]   [continue=yes]
+
+\definebar[underdot]    [undergraphic][mp=rules:under:dots]
+\definebar[underdots]   [underdot]    [continue=yes]
+\stoptyping
+
+A nasty side effect of the implementation is that because we look mostly at glyphs,
+optionally separated by glue or kern some text might get unseen and therefore not
+treated.
+
+\startbuffer
+\underbars{We see this \high{\tfxx ®} symbol \runninghbox to 1cm{\hss} often.}
+\underbar {We see this \high{\tfxx ®} symbol \runninghbox to 1cm{\hss} often.}
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlines
+\getbuffer
+\stoplines
+
+A running box is seen as text. As you (probably) expect, a nested ornamental
+rule is supported as well:
+
+\startbuffer
+\underbars{We see this \high{\tfxx\underdot{®}} symbol \runninghbox to 1cm{\hss} often.}
+\underbar {We see this \high{\tfxx\underdot{®}} symbol \runninghbox to 1cm{\hss} often.}
+\stopbuffer
+
+\typebuffer
+
+This time we get (you might need a magnifier to see it):
+
+\startlines
+\getbuffer
+\stoplines
+
+\stopsubject
+
+\startsubject[title=Shifting]
+
+We mention shifting here because it shares code with the bars. There are two
+shifts defined but you can define more:
+
+\starttyping
+\defineshift
+  [shiftup]
+  [method=0,
+   dy=-1,
+   unit=ex,
+   continue=yes,
+   style=\txx]
+
+\defineshift
+  [shiftdown]
+  [method=1,
+   dy=.3,
+   unit=ex,
+   continue=yes,
+   style=\txx,
+   color=]
+\stoptyping
+
+An example of using the commands defined this way is:
+
+\startbuffer
+Let's go \shiftup{up} and \shiftdown{down} a bit!
+\stopbuffer
+
+\typebuffer
+
+or: \inlinebuffer\ Here we just shift words but you can shift more than that
+although I haven't yet seen a useful example of that:
+
+\startbuffer
+We can \shiftup {\input{tufte}} whole paragraphs if we really want.
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+The formal definitions are given in \definition[defineshift, setupshift,
+startshift]. The \type {align} switch is there for directional (and testing)
+purposes and is normally not used (or even useful in a line). The \type {dy}
+is multiplied by the \type {factor} that itself can depend on the used font.
+
+\showdefinition{defineshift}
+\showdefinition{setupshift}
+\showdefinition{startshift}
+
+\stopsubject
+
+\startsubject[title=Fillers]
+
+The possibility of line fillers was mentioned by Mojca on the \CONTEXT\ mailing
+list and it's actually not that hard to implement them. The only need I ever had
+for it was to fill out lines on some legal form and that was actually just some
+fun challenge in \MKII\ times. The code got lost and never made it into \CONTEXT.
+This time it was added as a side effect of a thread at the tenth \CONTEXT\
+meeting.
+
+The ideas is to fill the rest of a line with some kind of (ornamental) rule. I'm
+not sure what sense it makes, even in legal documents. If it is to prevent
+additions then one should wonder if additions at the end of a (kind of arbitrary)
+broken line is what we should be afraid of most. So, for now, let's consider it
+an educational feature.
+
+\startbuffer
+\definelinefiller
+  [filler-1]
+  [height=.75\exheight,
+   distance=.25\emwidth,
+   rulethickness=.25\exheight,
+   textcolor=darkyellow,
+   before=\blank,
+   after=\blank,
+   color=darkred]
+
+\startlinefiller[filler-1]
+    \input ward
+\stoplinefiller
+\stopbuffer
+
+\typebuffer
+
+Here we define a filler. As you can see, a rule gets added at the end of a
+paragraph.
+
+\getbuffer
+
+\startbuffer
+\startalign[flushleft,broad]
+    \startlinefiller[filler-1]
+        \input ward
+    \stoplinefiller
+\stopalign
+\stopbuffer
+
+This time we don't justify:
+
+\typebuffer
+
+Now more lines get a rule appended:
+
+\getbuffer
+
+Before we continue it must be noted that the environment creates a paragraph. If
+you don't want that you need to use \type {\setlinefiller} instead. Next we show
+a \type {middle} alignment:
+
+\startbuffer
+\startalign[middle]
+    \startlinefiller[filler-1]
+        \input ward
+    \stoplinefiller
+\stopalign
+\stopbuffer
+
+\getbuffer
+
+\startbuffer
+\startalign[middle]
+    \startnarrower
+        \startlinefiller[filler-1]
+            \input ward
+        \stoplinefiller
+    \stopnarrower
+\stopalign
+\stopbuffer
+
+Let's add another level of complexity, left- and right skips:
+
+\typebuffer
+
+Here we get:
+
+\getbuffer
+
+The lines stay within the narrower boundaries but you can extend them
+to the margins if you like:
+
+\startbuffer
+\startalign[middle]
+    \startnarrower
+        \startlinefiller[filler-1][scope=global]
+            \input ward
+        \stoplinefiller
+    \stopnarrower
+\stopalign
+\stopbuffer
+
+\typebuffer
+
+This looks like:
+
+\getbuffer
+
+You can also use a \type {left} or \type {right} scope, as in:
+
+\startbuffer
+\startalign[middle]
+    \startnarrower
+        \startlinefiller[filler-1][scope=right]
+            \input ward
+        \stoplinefiller
+    \stopnarrower
+\stopalign
+\stopbuffer
+
+\typebuffer
+
+Only the right rules extend into the margins.
+
+\getbuffer
+
+\startbuffer
+\startalign[middle]
+    \startnarrower
+        \startlinefiller[filler-1][scope=right,location=right]
+            \input ward
+        \stoplinefiller
+    \stopnarrower
+\stopalign
+\stopbuffer
+
+You can get rid of the left rules:
+
+\typebuffer
+
+So:
+
+\getbuffer
+
+Of course these rules are somewhat boring so let's now kick in some \METAPOST.
+
+\startbuffer[mp]
+\setuplinefiller
+  [filler-1]
+  [mp=rules:filler:demo,
+  %threshold=.25\emwidth,
+   color=darkred]
+
+\startuseMPgraphic{rules:filler:demo}
+    drawarrow
+        if RuleDirection == "TRT" : reverse fi
+            ((0,RuleHeight) -- (RuleWidth,RuleHeight))
+        withpen
+            pencircle scaled RuleThickness
+        withcolor
+            if RuleOption == "left" : complemented fi RuleColor ;
+    setbounds currentpicture to
+        unitsquare xysized(RuleWidth,RuleHeight) ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer[mp] \getbuffer[mp]
+
+The previous example now looks like:
+
+\getbuffer
+
+\startbuffer
+\startalign[middle,r2l]
+    \startnarrower[4*middle]
+        \startlinefiller[filler-1]  [scope=global]
+            \input ward
+        \stoplinefiller
+    \stopnarrower
+\stopalign
+\stopbuffer
+
+This time we also change the direction and we can let the \METAPOST\ graphic
+adapt to that by reverting the arrows.
+
+\typebuffer
+
+The direction \type {TRT} is \TEX\ speak for a right|-|to|-|left direction. We
+use a latin script example for convenience.
+
+\getbuffer
+
+\startbuffer[mp]
+\startuseMPgraphic{rules:filler:demo}
+    drawarrow

+            if RuleOption == "right" : reverse fi

+

+When more text is to follow you should end a specification with \type {\relax} to
+make sure that the scanner stops looking for more arguments. With \type {\leaders}
+you can create flexible rules.
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+In \CONTEXT\ we also have so called frame rules:
+
+\startbuffer
+\color[darkred]{\frule
+    width 10cm
+    height 1cm
+    line   1mm
+\relax}
+\stopbuffer
+
+\typebuffer
+
+This will produce a rectangle:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+There are a few more keywords. Keep in mind that we actually have a new kind of
+primitive here, so we follow the \TEX\ conventions of keywords.
+
+\startbuffer
+\ruledhbox\bgroup
+    \darkgray \frule width 100mm height 10mm depth 8mm radius 2mm line 2pt type fill\relax
+    \hskip-100mm
+    \darkred  \frule width 100mm height 10mm depth 8mm radius 2mm line 2pt\relax
+    \hskip-100mm
+    \hbox to 100mm{\white \bold \hfill some handy word with frames\hfill}
+\egroup
+\stopbuffer
+
+\typebuffer
+
+Of course this is a rather low level way of doing frames and such, but when you
+like that kind of low level programming you get the possibility here.
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+You can combine this with existing mechanisms. Take the following:
+
+\startbuffer
+\defineoverlay[normalframe]
+  [\frule
+     width \overlaywidth
+     height\overlayheight
+     line  \overlaylinewidth
+  ]
+
+\defineoverlay[ovalframe]
+  [\frule
+     width  \overlaywidth
+     height \overlayheight
+     line   \overlaylinewidth
+     radius \overlayradius
+  ]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\hbox \bgroup
+    \framed                                  {test}\quad
+    \framed[frame=off]                       {test}\quad
+    \framed[background=normalframe,frame=off]{test}\quad
+    \framed[background=normalframe,frame=off]{test}\quad
+    \framed[corner=round]                    {test}\quad
+    \framed[corner=round]                    {test}\quad
+    \framed[background=ovalframe,frame=off]  {test}\quad
+    \framed[background=ovalframe,frame=off]  {test}\quad
+    \framed[background=ovalframe,frame=on]   {test}\quad
+    \framed[background=ovalframe,frame=on]   {test}\quad
+\egroup
+\stopbuffer
+
+This is a variant on the already available round corners:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+The above result is accomplished with:
+
+\typebuffer
+
+Given the examples in the previous sections it will be no surprise that we
+can also use \METAPOST.
+
+\startbuffer
+\startuseMPgraphic{demoshape:back}
+    fill
+        unitcircle xysized (RuleWidth,RuleHeight+RuleDepth)
+        withcolor RuleColor ;
+\stopuseMPgraphic
+
+\startuseMPgraphic{demoshape:fore}
+    draw
+        unitcircle xysized (RuleWidth,RuleHeight+RuleDepth)
+        withcolor RuleColor
+        withpen pencircle scaled 4RuleThickness ;
+\stopuseMPgraphic
+
+\hbox\bgroup
+    \darkgray \frule width 100mm height 10mm depth 8mm type mp line 2pt
+        data {\includeMPgraphic{demoshape:back}}
+    \relax
+    \hskip-100mm
+    \darkred \frule width 100mm height 10mm depth 8mm type mp line 2pt
+        data {\includeMPgraphic{demoshape:fore}}
+    \relax
+    \hskip-100mm
+    \hbox to 100mm{\white \bold \hfill some handy word with frames\hfill}
+\egroup
+\stopbuffer
+
+\typebuffer
+
+Or rendered:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+The \type {\blackrule} command is the more high level way to inject a rule.
+
+\startbuffer
+\blackrule
+  [width=10cm,
+   height=1cm,
+   depth=1cm,
+   color=darkred]
+\stopbuffer
+
+\typebuffer
+
+This produces a boring rule:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+Again we can revert to \METAPOST:
+
+\startbuffer
+\blackrule
+  [width=10cm,
+   height=1cm,
+   depth=1cm,
+   color=darkred,
+   type=mp,
+   mp=demoshape:back]
+\stopbuffer
+
+\typebuffer
+
+or:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+The formal definition of this command is shown in \definition [setupblackrules,
+blackrule].
+
+\showdefinition{setupblackrules}
+\showdefinition{blackrule}
+
+\stopsubject
+
+\startsubject[title=Hiding]
+
+In education a to be filled in text is often represented by a gap in the running text
+and the bar drawing mechanism supports this. THere is a predefined \type {\hiddenbar}
+command:
+
+\starttyping
+\definebar
+  [hiddenbar] [underbar]
+  [continue=yes,empty=yes,
+   left=\zwj,right=\zwj]
+\stoptyping
+
+\startbuffer
+\input ward \hiddenbar               {\color[red]{invisible}}
+\input ward \hiddenbar          {\quad\color[red]{invisible}\quad}

+\input ward \hiddenbar               {\color[red]{invisible}\quad\quad\quad\quad\quad\quad}
+\input ward
+\stopbuffer
+
+\getbuffer
+
+The previous text is generated with:
+
+\typebuffer
+
+Here is a variant that inserts spacing at the left and right edges. In this case
+the spacing is kept at a linebreak:

+\startsection [title={Introduction}]
+
+Occasionally a question pops up on the \CONTEXT\ mailing list and answering it
+becomes a nice distraction from a boring task at hand. The spreadsheet module is
+the result of such a diversion. As with more support code in \CONTEXT, this is
+not a replacement for \quote {the real thing} but just a nice feature for simple
+cases. The module is loaded with
+
+\starttyping
+\usemodule[spreadsheet]
+\stoptyping
+
+So this is (at least currently) not one of the core functionalities but an
+add||on. Of course some useful extensions might appear in the future.
+
+\stopsection
+
+\startsection [title={Spreadsheet tables}]
+
+We can use \LUA\ in each cell, because under the hood it is all \LUA. There is
+some basic parsing applied so that we can use the usual \type {A..Z} variables to
+access cells.
+
+\startbuffer[demo]
+\startspreadsheettable[test]
+  \startrow
+    \startcell 1.1         \stopcell
+    \startcell 2.1         \stopcell
+    \startcell A[1] + B[1] \stopcell
+  \stoprow
+  \startrow
+    \startcell 2.1         \stopcell
+    \startcell 2.2         \stopcell
+    \startcell A[2] + B[2] \stopcell
+  \stoprow
+  \startrow
+    \startcell A[1] + B[1] \stopcell
+    \startcell A[2] + B[2] \stopcell
+    \startcell A[3] + B[3] \stopcell
+  \stoprow
+\stopspreadsheettable
+\stopbuffer
+
+\typebuffer[demo]
+
+The rendering is shown in \in {figure} [spreadsheet:1]. Keep in mind that in
+\LUA\ all calculations are done using floats, at least in \LUA\ versions with
+version numbers preceding 5.3.
+
+\placefigure
+  [here]
+  [spreadsheet:1]
+  {A simple spreadsheet.}
+  {\getbuffer[demo]}
+
+The last cell can also look like this:
+
+\starttyping
+\startcell
+function()
+  local s = 0
+  for i=1,2 do
+    for j=1,2 do
+      s = s + dat[i][j]
+    end
+  end
+  return s
+end
+\stopcell
+\stoptyping
+
+The content of a cell is either a number or a function. In this example
+we just loop over the (already set) cells and calculate their sum. The
+\type {dat} variable accesses the grid of cells.
+
+\starttyping
+\startcell
+function()
+  local s = 0
+  for i=1,2 do
+    for j=1,2 do
+      s = s + dat[i][j]
+    end
+  end
+  tmp.total = s
+end
+\stopcell
+\stoptyping
+
+In this variant we store the sum in the table \type {tmp} which is local to the
+current sheet. Another table is \type {fnc} where we can store functions. This
+table is shared between all sheets. There are two predefined functions:
+
+\starttyping
+sum(columnname,firstrow,lastrow)
+fmt(specification,n)
+\stoptyping
+
+The \type {sum} function works top||down in columns, and roughly looks like
+this:
+
+\starttyping
+function sum(currentcolumn,firstrow,lastrow)
+  local r = 0
+  for i = firstrow, lastrow do
+    r = r + cells[currentcolumn][i]
+  end
+  return r
+end
+\stoptyping
+
+The last two arguments are optional:
+
+\starttyping
+sum(columnname,lastrow)
+\stoptyping
+
+This is equivalent to:
+
+\starttyping
+function sum(currentcolumn,lastrow)
+  local r = 0
+  for i = 1, lastrow do
+    r = r + cells[currentcolumn][i]
+  end
+  return r
+end
+\stoptyping
+
+While:
+
+\starttyping
+sum(columnname)
+\stoptyping
+
+boils down to:
+
+\starttyping
+function sum(currentcolumn)
+  local r = 0
+  for i = 1, currentrow do
+    r = r + cells[currentcolumn][i]
+  end
+  return r
+end
+\stoptyping
+
+Empty cells or cells that have no numbers are skipped. Let's now see these
+functions in action:
+
+\startbuffer[demo]
+\startspreadsheettable[test]
+  \startrow
+    \startcell 1.1 \stopcell \startcell 2.1 \stopcell
+  \stoprow
+  \startrow
+    \startcell 2.1 \stopcell \startcell 2.2 \stopcell
+  \stoprow
+  \startrow
+    \startcell
+      function()
+        local s = 0
+        for i=1,2 do
+          for j=1,2 do
+            s = s + dat[i][j]
+          end
+        end
+        context.bold(s)
+      end
+    \stopcell
+    \startcell
+      function()
+        local s = 1
+        for i=1,2 do
+          for j=1,2 do
+            s = s * dat[i][j]
+          end
+        end
+        context.bold(fmt("@.1f",s))
+      end
+    \stopcell
+  \stoprow
+\stopspreadsheettable
+\stopbuffer
+
+\typebuffer[demo]
+
+The result is shown in \in {figure} [spreadsheet:2]. Watch the \type {fmt} call:
+we use an at sign instead of a percent to please \TEX.
+
+\placefigure
+  [here]
+  [spreadsheet:2]
+  {Cells can be (complex) functions.}
+  {\getbuffer[demo]}
+
+Keep in mind that we're typesetting and that doing complex calculations is not
+our main objective. A typical application of this module is in making bills, for
+which you can combine it with the correspondence modules. We leave that as an
+exercise for the reader and stick to a simple example.

+\stopbuffer
+
+\typebuffer[demo]
+
+Here (and in \in {figure} [spreadsheet:8]) you see a quick and more
+readable way to format cell content. The \type {@} in the template is
+optional, but needed in cases like this:
+
+\starttyping
+@ "(@0.2f) EUR" 8.45
+\stoptyping
+
+A \type {@} is only prepended when no \type {@} is given in the template.

+\placefigure

+  {Cells can be formatted by using \type {@} directives.}
+  {\getbuffer[demo]}
+
+In practice this table we can be less specific and let \type {\sum} behave more
+automatical. That way the coding can be simplified (see \in {figure}
+[spreadsheet:7]) and also look nicer.

+There are a few more special start characters. This is demonstrated in \in

+It's possible to influence the rendering. The following example demonstrates

+\in {Figure} [spreadsheet:4] demonstrates how this gets rendered by

+periods and commas. This can be done as follows:
+

+\definehighlight[BoldAndGreen][style=bold,color=darkgreen]

+  {\getbuffer[setup,demo]}
+
+\stopsection
+
+\startsection[title={The \LUA\ end}]
+
+You can also use spreadsheets from within \LUA. The following example is
+rather straightforward:
+
+\startbuffer[demo-a]
+\startluacode
+context.startspreadsheettable { "test" }
+  context.startrow()
+    context.startcell() context("123456.78")   context.stopcell()
+  context.stoprow()
+  context.startrow()
+    context.startcell() context("1234567.89")  context.stopcell()
+  context.stoprow()
+  context.startrow()
+    context.startcell() context("A[1] + A[2]") context.stopcell()
+  context.stoprow()
+context.stopspreadsheettable()
+\stopluacode
+\stopbuffer
+
+\typebuffer[demo-a]
+
+However, even more \LUA|-|ish is the next variant:
+
+\startbuffer[demo-b]
+\startluacode
+  local set = moduledata.spreadsheets.set
+  local get = moduledata.spreadsheets.get
+
+  moduledata.spreadsheets.start("test")
+    set("test",1,1,"123456.78")
+    set("test",2,1,"1234567.89")
+    set("test",3,1,"A[1] + A[2]")
+  moduledata.spreadsheets.stop()
+
+  context.bTABLE()
+    context.bTR()
+      context.bTD() context(get("test",1,1)) context.eTD()
+    context.eTR()
+    context.bTR()
+      context.bTD() context(get("test",2,1)) context.eTD()
+    context.eTR()
+    context.bTR()
+      context.bTD() context(get("test",3,1)) context.eTD()
+    context.eTR()
+  context.eTABLE()
+\stopluacode
+\stopbuffer
+
+\typebuffer[demo-b]
+
+Of course the second variant does not make much sense as we can do this way
+more efficient by not using a spreadsheet at all:
+
+\startbuffer[demo-c]
+\startluacode
+  local A1, A2 = 123456.78, 1234567.89
+  context.bTABLE()
+    context.bTR()
+      context.bTD() context(A1)    context.eTD()
+    context.eTR()
+    context.bTR()
+      context.bTD() context(A2)    context.eTD()
+    context.eTR()
+    context.bTR()
+      context.bTD() context(A1+A2) context.eTD()
+    context.eTR()
+  context.eTABLE()
+\stopluacode
+\stopbuffer
+
+\typebuffer[demo-c]
+
+You can of course use format explicitly. Here we use the normal percent
+directives because we're in \LUA, and not in \TEX, where percentage
+signs are a bit of an issue.
+
+\startbuffer[demo-d]
+\startluacode
+  local A1, A2 = 123456.78, 1234567.89
+  local options = { align = "flushright" }
+  context.bTABLE()
+    context.bTR()
+      context.bTD(options)
+        context("%0.2f",A1)
+      context.eTD()
+    context.eTR()
+    context.bTR()

+      context.eTD()
+    context.eTR()
+  context.eTABLE()
+\stopluacode
+\stopbuffer
+
+\typebuffer[demo-d]
+
+As expected and shown in \in {figure} [spreadsheet:6], only the first and last
+variant gets the numbers typeset nicely.

+\startsection[title={Helper macros}]
+
+There are two helper macros that you can use to see what is stored in a
+spreadsheet:
+
+\starttyping
+\inspectspreadsheet[test]

+\stoptyping
+
+The first command reports the content of \type {test} to the console, and
+the second one typesets it in the running text:
+
+\blank

+
+Another helper function is \type {\doifelsespreadsheetcell}, You can use this

+\startsection[title=Description]
+
+This module is written in the process of defining a couple of styles for an
+educational math book. The macros provide you a way to visualize steps in for
+instance solving equations.
+
+The horizontal visualization is called stepchart, while the vertical alternative
+carries the name steptable. The vertical alternative has a special case that
+permits alignment on a mid symbol (in most cases a relation).
+
+The implementation uses a combination of \TEX\ and \METAPOST, and is set up in
+such a way that hyperlinks and alike will work okay.
+
+\stopsection
+
+\startsection[title=Structure]
+
+The horizontal stepcharts have at most four rows: two rows of cells with each an
+associated row of texts. The plural elements \type {cells} and \type {texts} each
+have two subelements. The \type {texts} elements are put between \type {cells}.
+
+\startbuffer
+<stepchart>
+  <cells> <top> some text </top> <bot> some text </bot> </cells>
+  <texts> <top> text </top> <bot> text </bot> </texts>
+  <cells> <top> some text </top> <bot> some text </bot> </cells>
+</stepchart>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+When a singular \type {cell} element is used in combination with the plural \type
+{texts}, we get one row of step cells with both top and bottom texts.
+
+\startbuffer
+<stepchart>
+  <cell> some text </cell>
+  <texts> <top> text </top> <bot> text </bot> </texts>
+  <cell> some text </cell>
+</stepchart>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+The third horizontal alternative only has singular elements, and as a result the
+texts are put above the step cells.
+
+\startbuffer
+<stepchart>
+  <cell> some cell </cell>
+  <cell> another cell </cell> <text> a bit of text </text>
+  <cell> third cell </cell> <text> more text </text>
+  <cell> last cell </cell>
+</stepchart>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+Normally, the lines go from cell to cell via a text. When you let the \type
+{cell} element follow by more than one \type {text} element (or their plural
+forms), all lines will start at the same point.
+
+\startbuffer
+<stepchart>
+  <cell> some text </cell>
+  <cell> some text </cell> <text> text 1 </text> <text> text 2 </text>
+  <cell> some text </cell>
+  <cell> some text </cell> <text> text 3 </text>
+  <cell> some text </cell>
+</stepchart>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+The vertical alternative (of course) looks different and permits pretty long
+explanations.
+
+\startbuffer
+<steptable>
+  <cell> cell 1 </cell>
+  <text> text 1 </text>

+</steptable>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+When the plural element \type {cells} is used, three sub||elements are expected.
+These align around the mid element \type {c2}.

+\typebuffer \processxmlbuffer
+
+\stopsection
+
+\startsection[title=Lines]
+
+You can draw lines normally or dashes and with or without arrows in both
+directions. This is controlled by the \type {alternative} option of \type
+{\setupSTEPaligntable}. As an example we use this table:
+
+\startbuffer[table]
+\startSTEPaligntable
+    \cells {$2c$} {$=$} {$2a+3b$}
+    \text  {with $a=5$}
+    \cells {$2c$}{$=$} {$10+3b$}
+    \text  {and $b=6$}
+    \cells {$2c$} {$=$} {$10+18$}
+    \text  {we get}
+\stopSTEPaligntable
+\stopbuffer
+
+\typebuffer[table]
+
+Next we show the (currently) 9 alternatives. The zero alternative draws no lines
+so there we can make the distance smaller.

+
+Because we don't want to clutter the examples with \MATHML\ we stick to a simple

+Although it is not too wise to set up the layout in the middle of a document, for

+change settings on a temporary basis by using groups. In \XML\ on the other hand,
+settings are bound to a category. So, in \TEX\ you can do this:

+   style=bold]
+
+\startSTEPchart

+\setupSTEPcells[demo-1][framecolor=darkred]
+\setupSTEPtexts[demo-1][framecolor=darkgreen]
+\setupSTEPlines[demo-1][alternative=4]

+\stopbuffer
+
+\typebuffer \getbuffer
+
+\noindentation This will be applied to:

+  <text class="demo-2"> type 8 </text>
+  <cell> type 9 </cell>
+</steptable>
+\stopbuffer
+
+\typebuffer
+
+\noindentation so that we get:
+
+\processxmlbuffer
+
+You can also use processing instructions:
+
+\startbuffer
+<stepchart>
+  <cells> <top> some text 1 </top> <bot> some text 2 </bot> </cells>
+  <?context-stepchart-directive text color darkred ?>
+  <texts> <top> text 3 </top> <bot> text 4 </bot> </texts>
+  <cells> <top> some text 5 </top> <bot> some text 6 </bot> </cells>
+  <?context-stepchart-directive text color darkblue ?>

+  <?context-stepchart-directive cell alternative 15 ?>
+  <cell> cell 15 </cell>
+</steptable>
+\stopbuffer
+
+\typebuffer \processxmlbuffer
+
+Some settings apply to the whole chart. In \TEX\ this is easy since we
+can group the whole chart including settings but in \XML\ this is somewhat
+problematic. We can however fall back on basic tex commands but it's
+probably better to use as category (class), like:
+
+\startbuffer
+\setupSTEPtexts[demo-5][distance=3em]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\noindentation So, the following works as expected:

+\startchapter[title=The \LUATEX\ \PDF\ backend]
+
+\startsection[title=Introduction]
+
+The original design of \TEX\ has a clear separation between the frontend and
+backend code. In principle, shipping out a page boils down to traversing the
+to|-|be|-|shipped|-|out box and translating the glyph, rule, glue, kern and list
+nodes into positioning just glyphs and rules on a canvas. The \DVI\ backend is
+therefore relatively simple, as the \DVI\ output format delegates to other
+programs the details of font inclusion and such into the final format; it just
+describes the pages.
+
+Because we eventually want color and images as well, there is a mechanism to pass
+additional information to post|-|processing programs. One can insert \type
+{\special}s with directives like \type {insert image named foo.jpg}. The frontend
+as well as the backend are not concerned with what goes into a special; the \DVI\
+post|-|processor of course is.
+
+The \PDF\ backend, on the other hand, is more complex as it immediately produces
+the final typeset result and, as such, offers possibilities to insert verbatim
+code (\type {\pdfliteral}), images (\type {\pdfximage} cum suis), annotations,
+destinations, threads and all kinds of objects, reuse typeset content (\type
+{\pdfxform} cum suis); in the end, there are all kinds of \type {\pdf...}
+commands. The way these were implemented in \LUATEX\ prior to 0.82 violates the
+separation between frontend and backend, an inheritance from \PDFTEX. Additional
+features such as protrusion and expansion add to that entanglement. However,
+because \PDF\ is an evolving standard, occasionally we need to adapt the related
+code. A separation of code makes sure that the frontend can become stable (and
+hopefully frozen) at some point. \footnote {In practice nowadays, the backend
+code changes little, because the \PDF\ produced by \LUATEX\ is rather simple and
+is easily adapted to the changing standard.}
+
+In \LUATEX\ we had already started making this separation of specialized code,
+such as a cleaner implementation of font expansion, but all these \type {\pdf...}
+commands were still pervasive, leading to fuzzy dependencies, checks for backend
+modes, etc.\ so a logical step was to straighten all this out. That way we give
+\LUATEX\ a cleaner core constructed from traditional \TEX, extended with \ETEX,
+\ALEPH|/|\OMEGA, and \LUATEX\ functionality.
+
+\stopsection
+
+\startsection[title=Extensions]
+
+A first step, then, was to transform generic (i.e.\ independent from the backend)
+functionality which was still (sort of) bound to \ALEPH\ and \PDFTEX, into core
+functionality. A second step was to reorganize the backend specific \PDF\ code,
+i.e.\ move it out of the core and into the group of extension commands. This
+extension group is somewhat special and originates in traditional \TEX; it is the
+way to add your own functionality to \TEX, the program.
+
+As an example for future programmers, Don Knuth added four (connected) primitives
+as extensions: \type {\openout}, \type {\closeout}, \type {\write} and \type
+{\special}. The \ALEPH\ and \PDFTEX\ engines, on the other hand, put some
+functionality in extensions and some in the core. This arose from the fact that
+dealing with variables in extensions is often inconvenient, as they are then seen
+as (unexpandable) commands instead of integers, token lists, etc. That the
+write|-|related commands are there is almost entirely due to being the
+demonstration of the mechanism; everything related to {\em reading} files is in
+the core. There is one property that perhaps forces us to keep the writers there,
+and that's the \type {\immediate} prefix. \footnote {Unfortunately we're stuck
+with \type {\immediate} in the backend; a \type {deferred} keyword would have
+been handier, especially since other backend|-|related commands can also be
+immediate.}
+
+In the process of separating, we reshuffled the code base a bit; the current use
+of the extensions mechanism still suits as an example and also gives us backward
+compatibility. However, new backend primitives will not be added there but rather
+in specific plugins (if needed at all).
+
+\stopsection
+
+\startsection[title=From whatsits to nodes]
+
+The \PDF\ backend introduced two new concepts into the core: (reusable) images
+and (reusable) content (wrapped in boxes). In keeping with good \TEX\ practice,
+these were implemented as whatsits (a node type for extensions); but this
+created, as a side effect, an anomaly in the handling of such nodes. Consider
+looping over a node list where we need to check dimensions of nodes; in \LUA, we
+can write something like this:
+
+\starttyping
+while n do
+    if n.id == glyph then
+        -- wd ht dp
+    elseif n.id == rule then
+        -- wd ht dp
+    elseif n.id == kern then
+        -- wd
+    elseif n.id == glue then
+        -- size stretch shrink
+    elseif n.id == whatsits then
+        if n.subtype == pdfxform then
+            -- wd ht dp
+        elseif n.subtype == pdfximage then
+            -- wd ht dp
+        end
+    end
+    n = n.next
+end
+\stoptyping
+
+So for each node in the list, we need to check these two whatsit subtypes. But as
+these two concepts are rather generic, there is no evident need to implement it
+this way. Of course the backend has to provide the inclusion and reuse, but the
+frontend can be agnostic about this. That is, at the input end, in specifying
+these two injects, we only have to make sure we pass the right information (so
+the scanner might differentiate between backends).
+
+Thus, in \LUATEX\ these two concepts have been promoted to core features:
+
+\starttabulate[|l|l|]
+\NC \type {\pdfxform}           \NC \type {\saveboxresource}             \NC \NR
+\NC \type {\pdfximage}          \NC \type {\saveimageresource}           \NC \NR
+\NC \type {\pdfrefxform}        \NC \type {\useboxresource}              \NC \NR
+\NC \type {\pdfrefximage}       \NC \type {\useimageresource}            \NC \NR
+\NC \type {\pdflastxform}       \NC \type {\lastsavedboxresourceindex}   \NC \NR
+\NC \type {\pdflastximage}      \NC \type {\lastsavedimageresourceindex} \NC \NR
+\NC \type {\pdflastximagepages} \NC \type {\lastsavedimageresourcepages} \NC \NR
+\stoptabulate
+
+The index should be considered an arbitrary number set to whatever the backend
+plugin decides to use as an identifier. These are no longer whatsits, but a
+special type of rule; after all, \TEX\ is only interested in dimensions. Given
+this change, the previous code can be simplified to:
+
+\starttyping
+while n do
+    if n.id == glyph then
+        -- wd ht dp
+    elseif n.id == rule then
+        -- wd ht dp
+    elseif n.id == kern then
+        -- wd
+    elseif n.id == glue then
+        -- size stretch shrink
+    end
+    n = n.next
+end
+\stoptyping
+
+The only consequence for the previously existing rule type (which, in fact, is
+also something that needs to be dealt with in the backend, depending on the
+target format) is that a normal rule now has subtype~0 while the box resource has
+subtype~1 and the image subtype~2.
+
+If a package writer wants to retain the \PDFTEX\ names, the previous table can be
+used; just prefix \type{\let}. For example, the first line would be (spaces
+optional, of course):
+
+\starttyping
+\let\pdfxform\saveboxresource
+\stoptyping
+
+\stopsection
+
+\startsection[title=Direction nodes]
+
+A similar change has been made for ``direction'' nodes, which were also
+previously whatsits. These are now normal nodes so again, instead of consulting
+whatsit subtypes, we can now just check the id of a node.
+
+It should be apparent that all of these changes from whatsits to normal nodes
+already greatly simplify the code base.
+
+\stopsection
+
+\startsection[title=Promoted commands]
+
+Many more commands have been promoted to the core. Here is an additional list of
+original \PDFTEX\ commands and their new counterparts (this time with the \type
+{\let} included):
+
+\starttyping

+\startsection[title=Backend commands]
+
+There are many commands that start with \type {\pdf} and, over the history of
+development of \PDFTEX\ and \LUATEX, some have been added, some have been
+renamed, others removed. Instead of the many, we now have just one: \type
+{\pdfextension}. A couple of usage examples:
+
+\starttyping
+\pdfextension literal {1 0 0 2 0 0 cm}
+\pdfextension obj     {/foo (bar)}
+\stoptyping
+
+Here, we pass a keyword that tells for what to scan and what to do with it. A
+backward|-|compatible interface is easy to write. Although it delegates a bit
+more management of these \type {\pdf} commands to the macro package, the
+responsibility for dealing with such low|-|level, error|-|prone calls is there
+anyway. The full list of \type {\pdfextension}s is given here. The scanning after
+the keyword is the same as for \PDFTEX.

+\startsection[title=Backend variables]
+
+As with commands, there are many variables that can influence the \PDF\ backend.
+The most important one was, of course, that which set the output mode
+(\type{\pdfoutput}). Well, that one is gone and has been replaced by \type
+{\outputmode}. A value of~1 means that we produce \PDF.
+
+One complication of variables is that (if we want to be compatible), we need to
+have them as real \TEX\ registers. However, as most of them are optional, an easy
+way out is simply not to define them in the engine. In order to be able to still
+deal with them as registers (which is backward compatible), we define them as
+follows:
+
+\starttyping
+\edef\pdfminorversion        {\pdfvariable minorversion}
+\edef\pdfcompresslevel       {\pdfvariable compresslevel}
+\edef\pdfobjcompresslevel    {\pdfvariable objcompresslevel}

+\edef\pdfxformattr           {\pdfvariable xformattr}
+\edef\pdfxformresources      {\pdfvariable xformresources}
+\stoptyping
+
+You can set them as follows (the values shown here are the initial values):
+
+\starttyping
+\pdfcompresslevel         9
+\pdfobjcompresslevel      1
+\pdfdecimaldigits         3
+\pdfgamma              1000
+\pdfimageresolution      71
+\pdfimageapplygamma       0
+\pdfimagegamma         2200
+\pdfimagehicolor          1
+\pdfimageaddfilename      1
+\pdfpkresolution         72
+\pdfinclusioncopyfonts    0
+\pdfinclusionerrorlevel   0
+\pdfignoreunknownimages   0
+\pdfreplacefont           0
+\pdfgentounicode          0
+\pdfpagebox               0
+\pdfminorversion          4
+\pdfuniqueresname         0
+
+\pdfhorigin             1in
+\pdfvorigin             1in
+\pdflinkmargin          0pt
+\pdfdestmargin          0pt
+\pdfthreadmargin        0pt
+\stoptyping
+
+Their removal from the frontend has helped again to clean up the code and, by
+making them registers, their use is still compatible. A call to \type
+{\pdfvariable} defines an internal register that keeps the value (of course this
+value can also be influenced by the backend itself). Although they are real
+registers, they live in a protected namespace:
+
+\startbuffer
+\meaning\pdfcompresslevel
+\stopbuffer
+
+\typebuffer
+
+which gives:
+
+{\tt\getbuffer}
+
+It's perhaps unfortunate that we have to remain compatible because a setter and
+getter would be much nicer. I am still considering writing the extension
+primitive in \LUA\ using the token scanner, but it might not be possible to
+remain compatible then. This is not so much an issue for \CONTEXT\ that always
+has had backend drivers, but, rather, for other macro packages that have users
+expecting the primitives (or counterparts) to be available.
+
+\startsection[title=Backend feedback]
+
+The backend can report on some properties that were also accessible via \type
+{\pdf...} primitives. Because these are read|-|only variables, another primitive
+now handles them: \type {\pdffeedback}. This primitive can be used to define
+compatible alternatives:
+
+\starttyping
+\def\pdflastlink       {\numexpr\pdffeedback lastlink\relax}
+\def\pdfretval         {\numexpr\pdffeedback retval\relax}
+\def\pdflastobj        {\numexpr\pdffeedback lastobj\relax}
+\def\pdflastannot      {\numexpr\pdffeedback lastannot\relax}
+\def\pdfxformname      {\numexpr\pdffeedback xformname\relax}
+\def\pdfcreationdate           {\pdffeedback creationdate}
+\def\pdffontname       {\numexpr\pdffeedback fontname\relax}
+\def\pdffontobjnum     {\numexpr\pdffeedback fontobjnum\relax}
+\def\pdffontsize       {\dimexpr\pdffeedback fontsize\relax}
+\def\pdfpageref        {\numexpr\pdffeedback pageref\relax}
+\def\pdfcolorstackinit         {\pdffeedback colorstackinit}
+\stoptyping
+
+The variables are internal, so they are anonymous. When we ask for the meaning of
+some that were previously defined:
+
+\starttyping
+\meaning\pdfhorigin
+\meaning\pdfcompresslevel
+\meaning\pdfpageattr
+\stoptyping
+
+we will get, similar to the above:
+
+\starttyping
+macro:->[internal backend dimension]
+macro:->[internal backend integer]
+macro:->[internal backend tokenlist]
+\stoptyping
+
+\stopsection
+
+\startsection[title=Removed primitives]
+
+Finally, here is the list of primitives that have been removed, with no
+\TEX|-|level equivalent available. Many were experimental, and they can be easily
+be provided to \TEX\ using \LUA.

+\startsection[title=Conclusion]
+
+The advantage of a clean backend separation, supported by just the three
+primitives \type {\pdfextension}, \type {\pdfvariable} and \type {\pdffeedback},
+as well as a collection of registers, is that we can now further clean the code
+base, which remains a curious mix of combined engine code, sometimes and
+sometimes not converted to C from \PASCAL. A clean separation also means that if
+someone wants to tune the backend for a special purpose, the frontend can be left
+untouched. We will get there eventually.
+
+All the definitions shown here are available in the file \type {luatex-pdf.tex},
+which is part of the \CONTEXT\ distribution.

+\startchapter[title=Possibly useful extensions]
+
+\startsection[title=Introduction]
+
+While working on \LUATEX, it is tempting to introduce all kinds of new fancy
+programming features. Arguments for doing this can be characterized by
+descriptions like \quote {handy}, \quote {speedup}, \quote {less code}, \quote
+{necessity}. It must be stated that traditional \TEX\ is rather complete, and one
+can do quite a lot of macro magic to achieve many goals. So let us look a bit
+more at the validity of these arguments.
+
+The \quote {handy} argument is in fact a valid one. Of course, one can always
+wrap clumsy code in a macro to hide the dirty tricks, but, still, it would be
+nicer to avoid needing to employ extremely dirty tricks. I found myself looking
+at old code wondering why something has to be done in such a complex way, only to
+realize, after a while, that it comes with the concept; one can get accustomed to
+it. After all, every programming language has its stronger and weaker aspects.
+
+The \quote {speedup} argument is theoretically a good one too, but, in practice,
+it's hard to prove that a speedup really occurs. Say we save 5\% on a job. This
+is nice for multipass on a server where many jobs run at the same time or after
+each other, but a little bit of clever macro coding will easily gain much more.
+Or, as we often see: sloppy macro or style writing will easily negate those
+gains. Another pitfall is that you can measure (say) half a million calls to a
+macro can indeed be brought down to a fraction of its runtime thanks to some
+helper, but, in practice, you will not see that gain because saving 0.1 seconds
+on a 10 second run can be neglected. Furthermore, adding a single page to the
+document will already make such a gain invisible to the user as that will itself
+increase the runtime. Of course, many small speedups can eventually accumulate to
+yield a significant overall gain, but, if the macro package is already quite
+optimized, it might not be easy to squeeze out much more. At least in \CONTEXT, I
+find it hard to locate bottlenecks that could benefit from extensions, unless one
+adds very specific features, which is not what we want.
+
+Of course one can create \quote {less} code by using more wrappers. But this can
+definitely have a speed penalty, so this argument should be used with care. An
+appropriate extra helper can make wrappers fast and the fewer helpers the better.
+The danger is in choosing what helpers. A good criterion is that it should be
+hard otherwise in \TEX. Adding more primitives (and overhead) merely because some
+macro package would like it would be bad practice. I'm confident that helpers for
+\CONTEXT\ would not be that useful for plain \TEX, \LATEX, etc., and vice versa.
+
+The \quote {necessity} argument is a strong one. Many already present extensions
+from \ETEX\ fall into this category: fully expandable expressions (although the
+implementation is somewhat restricted), better macro protection, expansion
+control, and the ability to test for a so|-|called csname (control sequence name)
+are examples.
+
+In the end, the only valid argument is \quote {it can't be done otherwise}, which
+is a combination of all these arguments with \quote {necessity} being dominant.
+This is why in \LUATEX\ there are not that many extensions to the language (nor
+will there be). I must admit that even after years of working with \TEX, the
+number of wishes for more facilities is not that large.
+
+The extensions in \LUATEX, compared to traditional \TEX, can be summarized as
+follows:
+
+\startitemize
+    \startitem
+        Of course we have the \ETEX\ extensions, and these already have
+        a long tradition of proven usage. We did remove the limited directional
+        support.
+    \stopitem
+    \startitem
+        From \ALEPH\ (follow-up on \OMEGA), part of the directional support and
+        some font support was inherited.
+    \stopitem
+    \startitem
+        From \PDFTEX, we took most of the backend code, but it has been improved
+        in the meantime. We also took the protrusion and expansion code, but
+        especially the latter has been implemented a bit differently (in the
+        frontend as well as in the backend).
+    \stopitem
+    \startitem
+        Some handy extensions from \PDFTEX\ have been generalized; other
+        obscure or specialized ones have been removed. So we now have
+        frontend support for position tracking, resources (images) and reusable
+        content in the core. The backend code has been separated a bit better and
+        only a few backend|-|related primitives remain.
+    \stopitem
+    \startitem
+        The input encoding is now \UTF-8, exclusively, but one can easily hook in
+        code to preprocess data that enters \TEX's parser using \LUA. The
+        characteristic catcode settings for \TEX\ can be grouped and switched
+        efficiently.
+    \stopitem
+    \startitem
+        The font machinery has been opened wide so that we can use the embedded
+        \LUA\ interpreter to implement any technology that we might want, with
+        the usual control that \TEX ies like. Some further limitations have been
+        lifted. One interesting point is that one can now construct virtual fonts
+        at runtime.
+    \stopitem
+    \startitem
+        Ligature construction, kerning and paragraph building have been separated
+        as a side effect of \LUA\ control. There are some extensions in that
+        area. For instance, we store the language and min|/|max values in the
+        glyph nodes, and we also store penalties with discretionaries. Patterns
+        can be loaded at runtime, and character codes that influence
+        hyphenation can be manipulated.
+    \stopitem
+    \startitem
+        The math renderer has been upgraded to support \OPENTYPE\ math. This has
+        resulted in many new primitives and extensions, not only to define
+        characters and spacing, but also to control placement of superscripts and
+        subscripts and generally to influence the way things are constructed. A
+        couple of mechanisms have gained control options.
+    \stopitem
+    \startitem
+        Several \LUA\ interfaces are available making it possible to manipulate the
+        (intermediate) results. One can pipe text to \TEX, write parsers, mess
+        with node lists, inspect attributes assigned at the \TEX\ end, etc.
+    \stopitem
+\stopitemize
+
+Some of the features mentioned above are rather \LUATEX\ specific, such as
+catcode tables and attributes. They are present as they permit more advanced
+\LUA\ interfacing. Other features, such as \UTF-8\ and \OPENTYPE\ math, are a
+side effect of more modern techniques. Bidirectional support is there because it
+was one of the original reasons for going forward with \LUATEX. The removal of
+backend primitives and thereby separating the code in a better way (see companion
+article) comes from the desire to get closer to the traditional core, so that
+most documentation by Don Knuth still applies. It's also the reason why we still
+speak of \quote {tokens}, \quote {nodes} and \quote {noads}.
+
+In the following sections I will discuss a few new low|-|level primitives. This
+is not a complete description (after all, we have reported on much already), and
+one can consult the \LUATEX\ manual to get the complete picture. The extensions
+described below are also relatively new and date from around version 0.85, the
+prelude to the stable version~1 release.
+
+\stopsection
+
+\startsection[title=Rules]
+
+For insiders, it is no secret that \TEX\ has no graphic capabilities, apart from
+the ability to draw rules. But with rules you can do quite a lot already. Add to
+that the possibility to insert arbitrary graphics or even backend drawing
+directives, and the average user won't notice that it's not true core
+functionality.
+
+When we started with \LUATEX, we used code from \PDFTEX\ and \OMEGA\ (\ALEPH),
+and, as a consequence, we ended up with many whatsits. Normal running text has
+characters, kerns, some glue, maybe boxes, all represented by a limited set of
+so|-|called nodes. A whatsit is a kind of escape as it can be anything an
+extension to \TEX\ needs to wrap up and put in the current list. Examples are (in
+traditional \TEX\ already) whatsits that write to file (using \type {\write}) and
+whatsits that inject code into the backend (using \type {\special}). The
+directional mechanism of \OMEGA\ uses whatsits to indicate direction changes.
+
+For a long time images were also included using whatsits, and basically one had
+to reserve the right amount of space and inject a whatsit with a directive for
+the backend to inject something there with given dimensions or scale. Of course,
+one then needs methods to figure out the image properties, but, in the end, all
+of this could be done rather easily.
+
+In \PDFTEX, two new whatsits were introduced: images and reusable so|-|called
+forms, and, contrary to other whatsits, these do have dimensions. As a result,
+suddenly the \TEX\ code base could no longer just ignore whatsits, but it had to
+check for these two when dimensions were important, for instance in the paragraph
+builder, packager, and backend.
+
+So what has this to do with rules? Well, in \LUATEX\ all the whatsits are now
+back to where they belong, in the backend extension code. Directions are now
+first|-|class nodes, and we have native resources and reusable boxes. These
+resources and boxes are an abstraction of the \PDFTEX\ images and forms, and,
+internally, they are a special kind of rule (i.e.\ a blob with dimensions).
+Because checking for rules is part of the (traditional) \TEX\ kernel, we could
+simply remove the special whatsit code and let existing rule|-|related code do
+the job. This simplified the code a lot.
+
+Because we suddenly had two more types of rules, we took the opportunity to add a
+few more.
+
+\starttyping
+\nohrule width 10cm height 2cm depth 0cm
+\novrule width 10cm height 2cm depth 0cm
+\stoptyping
+
+This is a way to reserve space, and it's nearly equivalent to the following
+(respectively):
+
+\starttyping
+{\setbox0\hbox{}\wd0=10cm\ht0=2cm\dp0=0cm\box0\relax}
+{\setbox0\vbox{}\wd0=10cm\ht0=2cm\dp0=0cm\box0\relax}
+\stoptyping
+
+There is no real gain in efficiency because keywords also take time to parse, but
+the advantage is that no \LUA\ callbacks are triggered. \footnote {I still am
+considering adding variants of \type {\hbox} and \type {\vbox} where no callback
+would be triggered.} Of course, this variant would not have been introduced had
+we still had just rules and no further subtypes; it was just a rather trivial
+extension that fit in the repertoire. \footnote {This is one of the things I
+wanted to have for a long time but seems less useful today.}
+
+So, while we were at it, yet another rule type was introduced, but this one has
+been made available only in \LUA. As this text is about \LUATEX, a bit of \LUA\
+code does fit into the discussion, so here we go. The code shown here is rather
+generic and looks somewhat different in \CONTEXT, but it does the job.
+
+First, let's create a straightforward rectangle drawing routine. We initialize
+some variables first, then scan properties using the token scanner, and, finally,
+we construct the rectangle using four rules. The packaged (so|-|called) hlist is
+written to \TEX.

+This function can be wrapped in a macro:

+The result is: \inlinebuffer
+
+A different approach follows. Again, we define a rule, but, this time we only set
+dimensions and assign some attributes to it. Normally, one would reserve some

+safe enough. Now there is no need to wrap the rule in a box.

+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can now also specify a radius and type, where \type {0} is a filled and \type
+{1} a stroked shape.
+
+\startbuffer
+\FrameRule
+    type   1
+    width  3cm
+    height 1cm
+    depth  5mm
+    line   0.2mm
+    radius 2.5mm
+\stopbuffer
+
+\typebuffer
+
+Since we specified a radius we get round corners: \inlinebuffer
+
+The nice thing about these extensions to rules is that the internals of \TEX\ are
+not affected much. Rules are just blobs with dimensions and the par builder, for
+instance, doesn't care what they are. There is no need for further inspection.
+Maybe future versions of \LUATEX\ will provide more useful subtypes.
+
+\stopsection
+
+\startsection[title=Spaces]
+
+Multiple successive spaces in \TEX\ are normally collapsed into one. But, what if
+you don't want any spaces at all? It turns out this is rather hard to achieve.
+You can, of course, change the catcodes, but that won't work well if you pass
+text around as macro arguments. Also, you would not want spaces that separate
+macros and text to be ignored, but only those in the typeset text. For such use,
+\LUATEX\ introduces \type {\nospaces}.
+
+This new primitive can be used to overrule the usual \type {\spaceskip}|-|related
+heuristics when a space character is seen in a text flow. The value~\type{1}
+specifies no injection, a value of \type{2} results in injection of a zero skip,
+and the default \type{0} gets the standard behavior. Below we see the results for
+four characters separated by spaces.
+
+\startlinecorrection \dontcomplain
+\startcombination[nx=3,ny=2,distance=1cm]

+\stoplinecorrection
+
+In case you wonder why setting the space related skips to zero is not enough:
+even when it is set to zero you will always get something. What gets inserted
+depends on \type {\spaceskip}, \type {\xspaceskip}, \type {\spacefactor} and font
+dimensions. I must admit that I always have to look up the details, as, normally,
+it's wrapped up in a spacing system that you implement once then forget about. In
+any case, with \type {\nospaces}, you can completely get rid of even an inserted
+zero space.
+
+\stopsection
+
+\startsection[title=Token lists]
+
+The following four primitives are provided because they are more efficient than
+macro|-|based variants: \type {\toksapp}, \type {\tokspre}, and \type {\e...}
+(expanding) versions of both. They can be used to append or prepend tokens to a
+token register.
+
+However, don't overestimate the gain that can be brought in simple situations
+with not that many tokens involved (read: there is no need to instantly change
+all code that does it the traditional way). The new method avoids saving tokens
+in a temporary register. Then, when you combine registers (which is also
+possible), the source gets appended to the target and, afterwards, the source is
+emptied: we don't copy but combine!
+
+Their use can best be demonstrated by examples. We employ a scratch register
+\type {\ToksA}. The examples here show the effects of grouping; in fact, they
+were written for testing this effect. Because we don't use the normal assignment
+code, we need to initialize a local copy in order to get the original content
+outside the group.

+\startsection[title=Active characters]
+
+We now enter an area of very dirty tricks. If you have read the \TEX\ book or
+listened to talks by \TEX\ experts, you will, for sure, have run into the term
+\quote {active} characters. In short, it boils down to this: each character has a
+catcode and there are 16 possible values. For instance, the backslash normally
+has catcode zero, braces have values one and two, and normal characters can be 11
+or 12. Very special are characters with code 13 as they are \quote {active} and
+behave like macros. In Plain \TEX, the tilde is one such active character, and
+it's defined to be a \quote {non|-|breakable space}. In \CONTEXT, the vertical
+bar is active and used to indicate compound and fence constructs.
+
+Below is an example of a definition:
+
+\starttyping
+\catcode`A=13
+\def A{B}
+\stoptyping
+
+This will make the \type {A} into an active character that will typeset a \type
+{B}. Of course, such an example is asking for problems since any \type {A} is
+seen that way, so a macro name that uses one will not work. Speaking of macros:
+
+\starttyping
+\def\whatever
+  {\catcode`A=13
+   \def A{B}}
+\stoptyping
+
+This won't work out well. When the macro is read it gets tokenized and stored and
+at that time the catcode change is not yet done so when this macro is called the
+A is frozen with catcode letter (11) and the \type {\def} will not work as
+expected (it gives an error). The solution is this:
+
+\starttyping
+\bgroup
+\catcode`A=13
+\gdef\whatever
+  {\catcode`A=13
+   \def A{B}}
+\egroup
+\stoptyping
+
+Here we make the \type {A} active before the definition and we use grouping
+because we don't want that to be permanent. But still we have a hard|-|coded
+solution, while we might want a more general one that can be used like this:
+
+\starttyping
+\whatever{A}{B}
+\whatever{=}{{\bf =}}
+\stoptyping
+
+Here is the definition of \type {whatever}:
+
+\starttyping
+\bgroup
+\catcode`~=13
+\gdef\whatever#1#2%
+  {\uccode`~=`#1\relax
+   \catcode`#1=13
+   \uppercase{\def\tempwhatever{~}}%
+   \expandafter\gdef\tempwhatever{#2}}
+\egroup
+\stoptyping
+
+If you read backwards, you can imagine that \type {\tempwhatever} expands into an
+active \type {A} (the first argument). So how did it become one? The trick is in
+the \type {\uppercase} (a \type {\lowercase} variant will also work). When casing
+an active character, \TEX\ applies the (here) uppercase and makes the result
+active too.
+
+We can argue about the beauty of this trick or its weirdness, but it is a fact
+that for a novice user this indeed looks more than a little strange. And so, a
+new primitive \type {\letcharcode} has been introduced, not so much out of
+necessity but simply driven by the fact that, in my opinion, it looks more
+natural. Normally the meaning of the active character can be put in its own
+macro, say:
+
+\starttyping
+\def\MyActiveA{B}
+\stoptyping
+
+We can now directly assign this meaning to the active character:
+
+\starttyping
+\letcharcode`A=\MyActiveA
+\stoptyping
+
+Now, when \type {A} is made active this meaning kicks in.
+
+\starttyping
+\def\whatever#1#2%
+  {\def\tempwhatever{#2}%
+   \letcharcode`#1\tempwhatever
+   \catcode`#1=13\relax}
+\stoptyping
+
+We end up with less code but, more important, it is easier to explain to a user
+and, in my eyes, it looks less obscure, too. Of course, the educational gain here
+wins over any practical gain because a macro package hides such details and only
+implements such an active character installer once.
+
+\stopsection
+
+\startsection[title=\type {\csname} and friends]
+
+You can check for a macro being defined as follows:
+
+\starttyping
+\ifdefined\foo
+    do something
+\else
+    do nothing
+\fi
+\stoptyping
+
+which, of course, can be obscured to:
+
+\starttyping
+do \ifdefined\foo some\else no\fi thing
+\stoptyping
+
+A bit more work is needed when a macro is defined using \type {\csname}, in which
+case arbitrary characters (like spaces) can be used:
+
+\starttyping
+\ifcsname something or nothing\endcsname
+    do something
+\else
+    do nothing
+\fi
+\stoptyping
+
+Before \ETEX, this was done as follows:
+
+\starttyping
+\expandafter\ifx\csname something or nothing\endcsname\relax
+    do nothing
+\else
+    do something
+\fi
+\stoptyping
+
+The \type {\csname} primitive will do a lookup and create an entry in the hash
+for an undefined name that then defaults to \type {\relax}. This can result in
+many unwanted entries when checking potential macro names. Thus, \ETEX's \type
+{\ifcsname} test primitive can be qualified as a \quote {necessity}.
+
+Now take the following example:
+
+\starttyping
+\ifcsname do this\endcsname
+    \csname do this\endcsname
+\else\ifcsname do that\endcsname
+    \csname do that\endcsname
+\else
+    \csname do nothing\endcsname
+\fi\fi
+\stoptyping
+
+If \type {do this} is defined, we have two lookups. If it is undefined and \type
+{do that} is defined, we have three lookups. So there is always one redundant
+lookup. Also, when no match is found, \TEX\ has to skip to the \type {\else} or
+\type {\fi}. One can save a bit by uglifying this to:
+
+\starttyping
+\csname do%
+    \ifcsname do this\endcsname this\else
+    \ifcsname do that\endcsname that\else
+                            nothing\fi\fi
+\endcsname
+\stoptyping
+
+This, of course, assumes that there is always a final branch. So let's get back
+to:
+
+\starttyping
+\ifcsname do this\endcsname
+    \csname do this\endcsname
+\else\ifcsname do that\endcsname
+    \csname do that\endcsname
+\fi\fi
+\stoptyping
+
+As said, when there is some match, there is always one test too many. In case you
+think this might be slowing down \TEX, be warned: it's hard to measure. But as
+there can be (m)any character(s) involved, including multi|-|byte \UTF-8\
+characters or embedded macros, there is a bit of penalty in terms of parsing
+token lists and converting to \UTF\ strings used for the lookup. And, because
+\TEX\ has to give an error message in case of troubles, the already|-|seen tokens
+are stored too.
+
+So, in order to avoid this somewhat redundant operation of parsing, memory
+allocation (for the lookup string) and storing tokens, the new primitive \type
+{\lastnamedcs} is now provided:
+
+\starttyping
+\ifcsname do this\endcsname
+    \lastnamedcs
+\else\ifcsname do that\endcsname
+    \lastnamedcs
+\fi\fi
+\stoptyping
+
+In addition to the (in practice, often negligible) speed gain, there are other
+advantages: \TEX\ has less to skip, and although skipping is fast, it still isn't
+a nice side effect (also useful when tracing). Another benefit is that we don't
+have to type the to|-|be|-|looked|-|up text twice. This reduces the chance of
+errors. In our example we also save 16 tokens (taking 64 bytes) in the format
+file. So, there are enough benefits to gain from this primitive, which is not a
+specific feature, but just an extension to an existing mechanism.
+
+It also works in this basic case:
+
+\starttyping
+\csname do this\endcsname
+\lastnamedcs
+\stoptyping
+
+And even this works:
+
+\starttyping
+\csname do this\endcsname
+\expandafter\let\expandafter\dothis\lastnamedcs
+\stoptyping
+
+And after:
+
+\starttyping
+\bgroup
+\expandafter\def\csname do this\endcsname{or that}
+\global\expandafter\let\expandafter\dothis\lastnamedcs
+\expandafter\def\csname do that\endcsname{or this}
+\global\expandafter\let\expandafter\dothat\lastnamedcs
+\egroup
+\stoptyping
+
+We can use \type {\dothis} that gives \type {or that} and \type {\dothat} that
+gives \type {or this}, so we have the usual freedom to be able to use something
+meant to make code clean for the creation of obscure code. % Amen!
+
+A variation on this is the following:
+
+\starttyping
+\begincsname do this\endcsname
+\stoptyping
+
+This call will check if \type {\do this} is defined, and, if so, will expand it.
+However, when \type {\do this} is not found, it does not create a hash entry. It
+is equivalent to:
+
+\starttyping
+\ifcsname do this\endcsname\lastnamedcs\fi
+\stoptyping
+
+but it avoids the \type {\ifcsname}, which is sometimes handy as these tests can
+interfere.
+
+I played with variations like \type {\ifbegincsname}, but we then quickly end up
+with dirty code due to the fact that we first expand something and then need to
+deal with the following \type {\else} and \type {\fi}. The two above|-|mentioned
+primitives are non|-|intrusive in the sense that they were relatively easy to add
+without obscuring the code base.
+
+As a bonus, \LUATEX\ also provides a variant of \type {\string} that doesn't add
+the escape character: \type {\csstring}. There is not much to explain to this:
+
+\starttyping
+\string\whatever<>\csstring\whatever
+\stoptyping
+
+This gives: \expanded{\type{\string\whatever<>\csstring\whatever}}.
+
+The main advantage of these several new primitives is that a bit less code is
+needed and (at least for \CONTEXT) leads to a bit less tracing output. When you
+enable \type {\tracingall} for a larger document or example, which is sometimes
+needed to figure out a problem, it's not much fun to work with the resulting
+megabyte (or sometimes even gigabyte) of output so the more we can get rid of,
+the better. This consequence is just an unfortunate side effect of the \CONTEXT\
+user interface with its many parameters. As said, there is no real gain in speed.
+
+\stopsection
+
+\startsection[title=Packing]
+
+Deep down in \TEX, horizontal and vertical lists eventually get packed. Packing
+of an \type {\hbox} involves:
+
+\startitemize[n,packed]
+\startitem ligature building (for traditional \TEX\ fonts), \stopitem
+\startitem kerning (for traditional \TEX\ fonts), \stopitem
+\startitem calling out to \LUA\ (when enabled) and \stopitem
+\startitem wrapping the list in a box and calculating the width. \stopitem
+\stopitemize
+
+When a \LUA\ function is called, in most cases, the location where it happens
+(group code) is also passed. But say that you try the following:
+
+\starttyping
+\hbox{\hbox{\hbox{\hbox foo}}}
+\stoptyping
+
+Here we do all four steps, while for the three outer boxes, only the last step
+makes any sense. And it's not trivial to avoid the application of the \LUA\
+function here. Of course, one can assign an attribute to the boxes and use that
+to intercept, but it's kind of clumsy. This is why we now can say:
+
+\starttyping
+\hpack{\hpack{\hpack{\hbox foo}}}
+\stoptyping
+
+There are also \type {\vpack} for a \type {\vbox} and \type {\tpack} for a \type
+{\vtop}. There can be a small gain in speed when many complex manipulations are
+done, although in, for instance, \CONTEXT, we already have provisions for that.
+It's just that the new primitives are a cleaner way out of a conceptually nasty
+problem. Similar functions are available on the \LUA\ side.
+
+\stopsection
+
+\startsection[title=Errors]
+
+We end with a few options that can be convenient to use if you don't care about
+exact compatibility.
+
+\starttyping
+\suppresslongerror
+\suppressmathparerror
+\suppressoutererror
+\suppressifcsnameerror
+\stoptyping
+
+When entering your document on a paper teletype terminal, starting \TEX, and then
+going home in order to have a look at the result the next day, it does make sense
+to catch runaway cases, like premature ending of a paragraph (using \type {\par}
+or equivalent empty lines), or potentially missing \type {$$}s. Nowadays, it's
+less important to catch such coding issues (and be more tolerant) because editing
+takes place on screen and running (and restarting) \TEX\ is very fast.
+
+The first two flags given above deal with this. If you set the first to any value
+greater than zero, macros not defined as \type {\long} (not accepting paragraph
+endings) will not complain about \cs{par} tokens in arguments. The second setting
+permits and ignores empty lines (also pars) in math without reverting to dirty
+tricks. Both are handy when your content comes from places that are outside of
+your control. The job will not be aborted (or hang) because of an empty line.
+
+The third setting suppresses the \type {\outer} directive so that macros that
+originally can only be used at the outer level can now be used anywhere. It's
+hard to explain the concept of outer (and the related error message) to a user
+anyway.
+
+The last one is a bit special. Normally, when you use \type {\ifcsname} you will
+get an error when \TEX\ sees something unexpandable or that can't be part of a
+name. But sometimes you might find it to be quite acceptable and can just
+consider the condition as false. When the fourth variable is set to non|-|zero,
+\TEX\ will ignore this issue and try to finish the check properly, so basically
+you then have an \type {\iffalse}.
+
+\stopsection
+
+\startsection[title=Final remarks]
+
+I mentioned performance a number of times, and it's good to notice that most
+changes discussed here will potentially be faster than the alternatives, but this
+is not always noticeable, in practice. There are several reasons.
+
+For one thing, \TEX\ is already highly optimized. It has speedy memory management
+of tokens and nodes and unnecessary code paths are avoided. However, due to
+extensions to the original code, a bit more happens in the engine than in decades
+past. For instance, \UNICODE\ fonts demand sparse arrays instead of fixed|-|size,
+256|-|slot data structures. Handling \UTF\ involves more testing and construction
+of more complex strings. Directional typesetting leads to more testing and
+housekeeping in the frontend as well as the backend. More keywords to handle, for
+instance \type {\hbox}, result in more parsing and pushing back unmatched tokens.
+Some of the penalty has been compensated for through the changing of whatsits
+into regular nodes. In recent versions of \LUATEX, scanning of \type {\hbox}
+arguments is somewhat more efficient, too.
+
+In any case, any speedup we manage to achieve, as said before, can easily become
+noise through inefficient macro coding or user's writing bad styles. And we're
+pretty sure that not much more speed can be squeezed out. To achieve higher
+performance, it's time to buy a machine with a faster \CPU\ (and a huge cache),
+faster memory (lanes), an \SSD, and regularly check your coding.

+\startchapter[title=Math new style: are we better off?]
+
+\startsection[title=Introduction]
+
+In this article I will summarize the state of upgrading math support in \CONTEXT\
+per mid 2013 in the perspective of demand, usability, font development and
+\LUATEX. There will be some examples, but don't consider this a manual: there are
+enough articles in the \type {mkiv}, \type {hybrid} and \type {about} series
+about specific topics; after all, we started with this many years ago. Where
+possible I will draw some conclusions with respect to the engine. Some comments
+might sound like criticism, but you should keep in mind that I wouldn't spend so
+much time on \TEX\ if I would not like it that much. It's just that the
+environment wherein \TEX\ is and can be used is not always as perfect as one
+likes it to be, i.e.\ bad habits and decisions once made can be pretty persistent
+and haunt us forever. I'm not referring to \TEX\ the language and program here,
+but more to its use in scientific publishing: in an early stage standards were
+set and habits were nurtured which meant that to some extent the coding resembles
+the early days of computing and the look and feel got frozen in time, in spite of
+developments in coding and evolving typographic needs. I think that the community
+has missed some opportunities to influence and improve matters which means that
+we're stuck with suboptimal situations and, although they are an improvement,
+\UNICODE\ math and \OPENTYPE\ math have their flaws.
+
+This is not a manual. Some aspects will be explained with examples, others are
+just mentioned. I've written down enough details in the documents that describe
+the history of \LUATEX\ and \MKIV\ and dedicated manuals and repeating myself
+makes not much sense. Even if you think that I talk nonsense, some of the
+examples might set you thinking. This article was written for the \TUG\ 2013
+conference in Japan. Many thanks to Barbara Beeton for proofreading and providing
+feedback.
+
+\stopsection
+
+\startsection[title=Some basic questions]
+
+Is there still a need for a program like \TEX ? Those who typeset math will argue
+that there is. After all, one of the reasons why \TEX\ showed up is typesetting
+math. In this perspective we should ask ourselves a few questions:
+
+\startitemize[packed]
+\startitem Is \TEX\ still the most adequate tool? \stopitem
+\startitem Does it make sense to invest in better machinery? \stopitem
+\startitem Have we learned from the past and improved matters? \stopitem
+\startitem What drives development and choices to be made? \stopitem
+\stopitemize
+
+The first question is not that easy to answer, unless you see proof in the fact
+that \TEX\ is still popular for typesetting a wide range of complex content (with
+critical editions being among the most complex). Indeed the program still
+attracts new users and developers. But we need to be realistic. First of all,
+there is some bias involved: if you have used a tool for many years, it becomes
+the one and only and best tool. But that doesn't necessarily make it the best
+tool for everyone.
+
+In this internet world finding a few thousand fellow users gives the impression
+that there is a wide audience but there can be of course thousandfold more users
+of other systems that don't fall into your scope. This is fine: I always wonder
+why there is not more diversity; for instance, we have only a few operating
+systems to choose from, and in communities around computer languages there is a
+tendency to evangelize (sometimes quite extreme). We should also take into
+account that a small audience can have a large impact so size doesn't matter
+much.
+
+As \TEX\ is still popular among mathematicians, we can assume that it hasn't lost
+its charm yet and often it is their only option. We have a somewhat curious
+situation that scientific publishers still want to receive \TEX\ documents |<|a
+demand that is not much different from organizations demanding \MSWORD\
+documents|>| but at the same time don't care too much about \TEX\ at all. Their
+involvement in user groups has started degrading long ago, compared to their
+profits; they don't invest in development; they are mostly profit driven, i.e.\
+those who submit their articles don't even own their sources any more, etc.\
+
+On the other hand, we have users who make their own books (self|-|publishing) and
+who go, certainly in coding and style, beyond what publishers do: they want to
+use all kinds of fonts (and mixtures), color, nicely integrated graphics, more
+interesting layouts, experiment with alternative presentations. But especially
+for documents that contain math that also brings a price: you have to spend more
+time on thinking about presenting the content and coding of the source. This all
+means that if we look at the user side, alternative input is an option,
+especially if they want to publish on different media. I know that there are
+\CONTEXT\ users who make documents (or articles) with \CONTEXT, using whatever
+coding suits best, and do some conversion when it has to be submitted to a
+journal. Personally I think that the lack of interest of (commercial) publishers,
+and their rather minimal role in development, no longer qualifies them to come up
+with requirements for the input, if only because in the end all gets redone
+anyway (in Far Far Away).
+
+It means that, as long as \TEX\ is feasible, we are relatively free to move on
+and experiment with alternative input. Therefore the other two questions become
+relevant. The \TEX\ engines are adapted to new font technology and a couple of
+math fonts are being developed (funded by the user groups). Although the \TEX\
+community didn't take the lead in math font technology we are catching up. At the
+same time we're investing much time in new tools, but given the fact that much
+math is produced for publishers it doesn't get much exposure. Scientific
+publishing is quite traditional and like other publishing lags behind and
+eventually will disappear in its current form. It could happen that one morning
+we find out that all that \quote {publishers want it this or that way} gets
+replaced by ways of publishing where authors do all themselves. A publisher (or
+his supplier) can keep using a 20-year old \TEX\ ecosystem without problems and
+no one will notice, but users can go on and come up with more modern designs and
+output formats and in that perspective the availability of modern engines and
+fonts is good. I've said it before: for \CONTEXT\ user demand drives development.
+
+In the next sections I will focus on different aspects of math and how we went
+from \MKII\ to \MKIV. I will also discuss some (pending) issues. For each aspect
+I will try to answer the third question: did matters improve and if not, and how
+do we cope with it (in \CONTEXT).
+
+\stopsection
+
+\startsection[title=The math script]
+
+All math starts with symbols and|/|or characters that have some symbolic meaning
+and in \TEX\ speak this can be entered in a rather natural way:
+
+\startbuffer
+$ y = 2x + b $
+\stopbuffer
+
+\typebuffer
+
+In order to let \TEX\ know it's math (the equivalent of) two dollar signs are
+used as triggers. The output of this input is: \inlinebuffer. But not all is that
+simple, for instance if we want to square the x, we need to use a superscript
+signal:
+
+\startbuffer
+$ y = x^2 + ax + b $
+\stopbuffer
+
+\typebuffer
+
+The \type {^} symbol results in a smaller \type {2} raised after the \type {x} as
+in \inlinebuffer. Ok, this \type {^} and its cousin \type {_} are well known
+conventions so we stick to this kind of input.
+
+\startbuffer
+$ y = \sqrt { x^2 + ax + b } $
+\stopbuffer
+
+A next level of complexity introduces special commands, for instance a command
+that will wrap its argument in a square root symbol: \inlinebuffer.
+
+\typebuffer
+
+It is no big deal to avoid the backslash and use this kind of coding:
+
+\startbuffer
+\asciimath { y = sqrt ( x^2 + ax + b ) }
+\stopbuffer
+
+\typebuffer
+
+In fact, we have been supporting scientific calculator input for over a decade in
+projects where relatively simple math had to be typeset. In one of our
+longest|-|running math related projects the input went from \TEX, to content
+\MATHML\ to \OPENMATH\ and via presentation \MATHML\ ended up as a combination of
+some kind of encoding that web browsers can deal with. This brings us to reality:
+it's web technology that drives (and will drive math) coding. Unfortunately
+content driven coding (like content \MATHML) does not seem to be the winner here,
+even if it renders easier and is more robust.
+
+Later I will discuss fences, like parentheses. Take this dummy formula:
+
+\starttyping
+$ (x + 1) / a = (x - 1) / b $
+\stoptyping
+
+In a sequential (inline) rendering this will come out okay. A more display mode
+friendly variant can be:
+
+\starttyping
+$ \frac{x + 1}{a} = \frac{x - 1}{b} $
+\stoptyping
+
+which in pure \TEX\ would have been:
+
+\starttyping
+$ {x + 1} \over {a} = {x - 1} \over {b} $
+\stoptyping
+
+The main difference between these two ways of coding is that in the second
+(plain) variant the parser doesn't know in advance what it is dealing with. There
+are a few cases in \TEX\ where this kind of parsing is needed and it complicates
+not only the parser but also is not too handy at the macro level. This is why the
+\type {\frac} macro is often used instead. In \LUATEX\ we didn't dare to get rid
+of \type {\over} and friends, even if we're sure they are not used that often by
+users.
+
+In inline or in more complex display math, the use of fences is quite normal.
+
+\startbuffer
+$ ( \frac{x + 1}{a}  + 1 )^2  = \frac{x - 1}{b} $
+\stopbuffer
+
+\typebuffer
+
+Here we have a problem. The parentheses don't come out well.
+
+\blank \noindentation \getbuffer \blank
+
+We have to do this:
+
+\startbuffer
+$ \left( \frac{x + 1}{a}  + 1 \right)^2  = \frac{x - 1}{b} $
+\stopbuffer
+
+\typebuffer
+
+in order to get:
+
+\blank \noindentation \getbuffer \blank
+
+Doing that \type{\left}|-|\type{\right} trick automatically is hard, although in
+\MATHML, where we have to interpret operators anyway it is somewhat easier. The
+biggest issue here is that these two directives need to be paired. In \ETEX\ a
+\type {\middle} primitive was added to provide a way to have bars adapt their
+height to the surroundings. Interesting is that where at the character level a
+\type {(} has a math property \type {open} and \type {)} has \type {close}. The
+bar, as we will see later, can also act as separator but this property does not
+exist. Because properties (classes in \TEX\ speak) determine spacing we have a
+problem here. So far we didn't extend the repertoire of properties in \LUATEX\ to
+suit our needs (although in \CONTEXT\ we do have more properties).
+
+If you are a \TEX\ user typesetting math, you can without doubt come up with more
+cases of source coding that have the potential of introducing complexities. But
+you will also have noticed that in most cases \TEX\ does a pretty good job on
+rendering math out of the box. And macro packages can provide additional
+constructs that help to hide the details of fine tuning (because there is a lot
+that {\em can} be fine tuned).
+
+In \TEX\ there are a couple of special cases that we can reconsider in the
+perspective of (for instance) faster machines. Normally a macro cannot have a
+\type {\par} in one of its arguments. By defining them as \type {\long} this
+limitation goes away. This default limitation was handy in times when a run was
+relatively slow and grabbing a whole document source as argument due to a missing
+brace had a price. Nowadays this is no real issue which is why in \LUATEX\ we can
+disable \type {\long} which indeed we do in \CONTEXT. On the agenda is to also
+permit \type {\par} in a math formula, as currently \TEX\ complains loudly.
+Permitting a bit more spacy formula definitions (by using empty lines) would be a
+good thing.
+
+Another catch is that in traditional \TEX\ math characters cannot be used outside
+math. That restriction has been lifted. Of course users need to be aware of the
+fact that a mix of math and text symbols can be visually incompatible.
+
+In the examples we used \type {^} and \type {_} and in math mode these have
+special meanings. Traditionally in text mode they trigger an error message. In
+\CONTEXT\ \MKIV\ we have made these characters regular characters but in math
+mode they still behave as expected. \footnote {In an intermediate version \type
+{\nonknuthmode} and \type {\donknuthmode} controlled this.} In a similar fashion
+the \type {&} is an ampersand and when you enable \type {\asciimode} the dollar
+and percent signs also become regular. \footnote {Double percent signs act as
+comments then which is comparable to comments in some programming languages.} In
+\LUATEX\ we have introduced primitives for all characters (or more precisely:
+catcodes) that \TEX\ uses for special purposes like opening and closing math
+mode, scripts, table alignment, etc.
+
+In projects that involve \XML\ we use \MATHML. In \TEX\ many characters can be
+inserted using commands that are tuned for some purpose. The same character can
+be associated with several commands. In \MATHML\ entities and \UNICODE\
+characters are used instead of commands. Interesting is that whenever we get math
+coded that way, there is a good chance that the coding is inconsistent. Of course
+there are ways in \MATHML\ to make sure that a character gets interpreted in the
+right way. For instance, the \type {mfenced} element drives the process of
+(matching) parenthesis, brackets, etc.\ and a renderer can use this property to
+make sure these symbols stretch vertically when needed. However, using \type {mo}
+in an \type {mrow} for a fence is also an option, but that demands some more
+(fuzzy) analysis. I will not go into details here, but some of the more obscure
+options and flags in \CONTEXT\ relate to overcoming issues with such cases.
+
+I have no experience with how \MSWORD\ handles math input, apart from seeing some
+demos. But I know that there is some input parsing involved that is a mixture
+between \TEX\ and analysis. Just as word processing has driven math font
+technology it might be that at some point users expect more clever processing of
+input. To a large extent \TEX\ users already expect that. Where till now \TEX\
+could inspire the way word processers do math, word processors can inspire \TEX
+ies way of inputting text.
+
+So, we have \MATHML, which, in spite of being structured, is still providing
+users a lot of freedom. Then there are word processors, where mouse clicks and
+interpretation does the job. And of course we have \TEX, with its familiar
+backslashes. Let us consider math, when seen in print, as a script to express the
+math language. And indeed, in \OPENTYPE, math is one of the official scripts
+although one where a rather specific kind of machinery is needed in order to get
+output.
+
+I could show more complex math formulas but no matter what notation is used,
+coding will always be somewhat cumbersome and handywork. Math formula coding and
+typesetting remains a craft in itself and \TEX\ notation will keep its place for
+a while. So, with that aspect settled we can continue to discuss rendering.
+
+% So what drives development? I tend to forget about publishers, who, if \TEX\ is
+% known at all in the organization, outsource anyway, and focus on users. One of
+% these users is me, and we do some work for publishers, but they seldom know or
+% care what tools we use. Users also contribute to development: for instance user
+% groups spend considerable money on font development. Interesting is that given
+% the substantial profits of publishers who indirectly still benefit from this it
+% are the users who invest in the tools. In my opinion this also puts them in
+% charge. And of course, developments with respect to input, output and fonts are a
+% driving force behind engine development. There are some more factors: control, as
+% \TEX\ is a programming language, and joy, as manipulating look and feel can be
+% fun. In the future these two will probably dominate over the others, when
+% typesetting and print become more specialized.
+
+\stopsection
+
+\startsection[title=Alphabets]
+
+I have written about math alphabets before so let's keep it simple here. I think
+we can safely say that most math support mechanisms in macro packages are
+inspired by plain \TEX. In traditional \TEX\ we have fonts with a limited number
+of glyphs and an eight|-|bit engine, so in order to get the thousands of possible
+characters mapped onto glyphs the right one has to be picked from some font. In
+addition to characters that you find in \UNICODE, there are also variants,
+additional sizes and bits and pieces that are used in constructing large
+characters, so in practice a math font is quite large. But it is unlikely that we
+will ever run into a situation where fonts pose limits.
+
+The easiest way is of course a direct mapping: an \quote {a} entered in math mode
+becomes an \quote{$a$} simply because the current font at that time has an italic
+shape in the slot referenced by the character. If we want a bold shape instead,
+we can switch to another font and still input an \quote {a}. The 16 families
+available are normally enough for the alphabets that we need. Because symbols can
+be collected in any font, they are normally accessed by name, like \type {\oplus}
+or $\oplus$.
+
+In \UNICODE\ math the math italic \quote {$a$} has slot \type {U+1D44E} and
+directly entering this character in a \UNICODE\ aware \TEX\ engine also has to
+give that \quote {$a$}. In fact, it is the only official way to get that
+character and the fact that we can enter the traditional \ASCII\ characters and
+get an italic shape is a side effect of the macro package, for instance the way
+it defines math fonts and families. \footnote {Our experience is that even when
+for instance \MATHML\ permits coding of math in \XML, copy editors have no
+problem with abusing regular italic font switches to simulate math. This can
+result is a weird mix of math rendering.}
+
+\definefont[mathdemo][file:texgyrepagellamath*mathematics]
+
+Before we move on, let's stress a limitation in \UNICODE\ with respect to math
+alphabets. It has always been a principle of \UNICODE\ committees to never
+duplicate entries. So, thanks to the availability of some characters in
+traditional (font) encodings, we ended up with some symbols that are used for
+math in the older regions of \UNICODE. As a consequence some alphabets have gaps.
+The only real reason I can come up with for accepting these gaps is that old
+documents using these symbols would be not compatible with gapfull \UNICODE\ math
+but I could argue that a document that uses those old codepoints uses commands
+(and needs some special fonts) to get the other symbols anyway, so it's unlikely
+to be a real math document. On the other hand, once we start using \UNICODE\ math
+we could benefit from gapless alphabets simply because otherwise each application
+would have to deal with the exceptions. One can come up with arguments like
+\quotation {just use this or that library} but that assumes persistence, and also
+forces everyone to use the same approach. In fact, if we hide behind a library we
+could as well have hidden the vectors (alphabets) as well. But as they are
+exposed, the gaps stand out as an anomaly. \footnote {One good reason for not
+having the gaps is that when users cut and paste there is no way to know if \type
+{U+210E} is used as Planck constant or variable of some sort, i.e.\ the not
+existing \type {0x1D455}. There is no official way to tag it as something math,
+and even then, as it has no code point it so has lost it's meaning, contrary to a
+copied $i$.} Let's illustrate this with an example. Say that we load the \TEX
+Gyre Pagella math font and call up a few characters:
+
+\startbuffer
+\definefont[mathdemo][file:texgyrepagellamath*mathematics]
+\mathdemo \char"0211C \char"1D507 \char"1D515
+\stopbuffer
+
+\typebuffer
+
+The \UNICODE\ fraktur math alphabet is continuous but the \quote {MATHEMATICAL
+FRAKTUR CAPITAL R} is missing as we already have the \type {BLACK-LETTER CAPITAL
+R} instead. So, this is why we only see two characters show up. It means that in
+the input we cannot have a \type {U+1D515}.
+
+\blank \start \getbuffer \stop \blank
+
+Of course we can cheat and fill in the gap:
+
+\startbuffer
+\definefontfeature
+  [mymathematics]
+  [mathematics]
+  [mathgaps=yes]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This feature will help us cheat:
+
+\startbuffer
+\definefont[mathdemo][file:texgyrepagellamath*mymathematics]
+\mathdemo \char"0211C \char"1D507 \char"1D515
+\stopbuffer
+
+\typebuffer
+
+This time we can use the character. I wonder what would happen if the \TEX\
+community would simply state that slot \type {U+1D515} is valid. I bet that math
+related applications would support it, as they also support more obscure
+properties of \TEX\ input encoding.
+
+\blank \start \getbuffer \stop \blank
+
+If you still wonder why I bother about this, here is a practical example. The
+\SCITE\ editor that I use is rather flexible and permits me to implement advanced
+lexers for \CONTEXT\ (and especially hybrid usage). It also permits to hook in
+\LUA\ code and that way the editor can (within bounds) be extended. As an example
+I've added some button bars that permit entering math alphabets. Of course the
+appearance depends on the font used but operating systems tend to consult
+multiple fonts when the core font of the editor doesn't provide a glyph.
+
+\startlinecorrection
+    \externalfigure[still-math-stripe.png][width=\textwidth]
+\stoplinecorrection
+
+Here I show a small portion of the stripe with buttons that inject the shown
+characters. What happens in the rendering is that first the used font is
+consulted and that one has a couple of \quote {BLACK LETTER CAPITAL}s so they get
+used. The others are \quote {MATHEMATICAL FRAKTUR CAPITAL}s and since the font is
+not a math font the renderer takes them from (in this case) Cambria Math, which
+is why they look so different, especially in proportion. Of course we could start
+out with Cambria but it has no monospace (which I want for editing) and is a less
+complete text font, so we have a chicken||egg problem here. It is one reason why
+as part of the math font project we extend the Dejavu Sans Mono with proper
+(consistent) math symbols. Anyhow, it illustrates why gaps are kind of evil from
+the application point of view.

+SCRIPT SMALL L} and \typ {SCRIPT SMALL L} (usually \type {\ell} in macro
+packages? Indeed there is, although at the time of this writing interestingly
+Latin Modern fonts lacked the mathematical one (which in \CONTEXT\ math mode
+normally results in an upright drop||in). Such details become important when math
+is edited by someone not familiar with the distinction between a variable (or
+whatever) represented by a script shape and the length operator. There seems not
+to be agreement by font designers about the shapes being upright or italic, so
+some confusion will remain, although this does not matter as long as within the
+font they differ.

+
+As math uses greek and because greek was already present in \UNICODE\ when math
+was recognized as script and got its entries, you can imagine that there are some
+issues there too, but let us move on to using alphabets.
+
+In addition to a one||to||one mapping from a font slot onto a glyph, you can
+assign properties to characters that map them onto a slot in some family (which
+itself relates to a font). This means that in a traditional approach you can
+choose among two methods:
+
+\startitemize[packed]
+
+    \startitem
+        You define several fonts (or instances of the same font) where the
+        positions of regular characters point to the relevant shape. So, when an
+        italic family is active the related font maps character \type {U+61} as
+        well as \type {U+1D44E} to the same italic shape \quote {$ \utfchar
+        {0x1D44E} $}. A switch from italic to bold italic is then a switch in
+        family and in that family the \type {U+61} as well as \type {U+1D482}
+        become bold italic \quote {$ \utfchar {0x1D482} $}.
+    \stopitem
+
+    \startitem
+        You define just one font. The alphabet (uppercase, lowercase and sometimes
+        digits and a few symbols) gets codes that point to the right shape. When we
+        switch from italic to bold italic, these codes get reassigned.
+    \stopitem
+
+\stopitemize
+
+The first method has some additional overhead in defining fonts (you can use
+copies but need to make sure that the regular \ASCII\ slots are overloaded) but
+the switch from italic to bold italic is fast, while in the second variant there
+is less overhead in fonts but reassigning the codes with a style switch has some
+overhead (although in practice this overhead is can be neglected because not that
+many alphabet switches take place). In fact, many \TEX\ users will probably stick
+to traditional approaches where verbose names are used and these can directly
+point to the right shape.
+
+In \CONTEXT, when we started with \MKIV, we immediately decided to follow another
+approach. We only have one family and we assume \UNICODE\ math input. Ok, we do
+have a few more families, but these relate to a full bold math switch and
+right||to||left math. We cannot expect users to enter \UNICODE\ math, if only
+because support in editors is not that advanced, so we need to support the
+\ASCII\ input method as well.
+
+We have one family and don't redefine character codes, but set properties
+instead. We don't switch fonts, but properties. These properties (often a
+combination) translates into the remapping of a specific character in the input
+onto a \UNICODE\ math code point that then directly maps onto a shape. This
+approach is quite clean and efficient at the \TEX\ end but carries quite a lot of
+overhead at the \LUA\ end. So far users never complained about it, maybe because
+\CONTEXT\ math support is rather optimized. Also, dealing with characters is only
+part of math typesetting and we have subsystems that use far more processing
+power.
+
+Because math characters are organized in classes, we need to set them up. Because
+for several reasons we collect character properties in a database we also define
+these character properties in \LUA. This means that the \type {math-*} files are
+relatively small. So we have much less code at the \TEX\ end, but quite a lot at
+the \LUA\ end. This assumes a well managed \LUA\ subsystem because as soon as
+users start plugging in their code, we have to make sure that the core system
+still functions well. The amount of code involved in virtual math fonts is also
+relatively large but most of that is becoming sort of obsolete.
+
+Relatively new in \CONTEXT\ is the possibility in some mathematical constructs to
+configure the math style (text, script, etc.) and in some cases math classes can
+be influenced. Control over styles is somewhat more convenient in \LUATEX,
+because we can consult the current style in some cases. I expect more of this
+kind of control in \CONTEXT, although most users probably never need it. These
+kinds of features are meant for users like Aditya Mahajan, who likes to explore
+such features and also takes advantage of the freedom to experiment with the look
+and feel of math.
+
+The font code that relates to math is not the easiest to understand but this is
+because it has to deal with bold as well as bidirectional math in efficient ways.
+Because in \CONTEXT\ we have additional sizes (\type {x}, \type {xx}, \type {a},
+\type {b}, \type {c}, \type {d}, \unknown) we also have some delayed additional
+defining going on. This all might sound slower to set up but in the end we win
+some back by the fact that we have fewer fonts to load. The price that a
+\CONTEXT\ user pays in terms of runtime is more influenced by the by now large
+sequence of math list manipulators than by loading a font.
+
+An unfortunate shortcoming of \UNICODE\ math is that some alphabets have gaps.
+This is because characters can only end up once in the standard. Given the number
+of weird characters showing up in recent versions, I think this condition is
+somewhat over the top. It forces applications that deal with \UNICODE\ math to
+implement exceptions over and over again. In \CONTEXT\ we assume no gaps and
+compensate for that.
+
+There are several ways that characters can become glyphs. An \quote {a} can
+become an italic, bold, bold italic but also end up sans serif or monospace.
+Because there are several artistic interpretations possible, some fonts provide a
+so|-|called alternate. In the case of for instance greek we can also distinguish
+upright or slanted (italic). A less well known transformation is variants driven
+by \UNICODE\ modified directives. If we forget about bidirectional math and full
+bold (heavy) math we can (currently) identify 6 axes:
+
+\starttabulate[|c|l|l|]
+\HL
+\NC \bf axis \NC \bf use  \NC \bf choices \NC \NR
+\HL
+\NC 1        \NC type     \NC digits, lowercase \& uppercase latin \& greek, symbols \NC \NR
+\NC 2        \NC alphabet \NC regular, sans serif, monospace, blackboard, fraktur, script \NC \NR
+\NC 3        \NC style    \NC upright, italic, bold, bolditalic \NC \NR
+\NC 4        \NC variant  \NC alternative rendering provided by font \NC \NR
+\NC 5        \NC shape    \NC unchanged, upright, italic \NC \NR
+\NC 6        \NC \UNICODE \NC alternative rendering driven by \UNICODE\ modifier \NC \NR
+\HL
+\stoptabulate
+
+Apart from the last one, this is not new, but it is somewhat easier to support
+this consistently. It's one of the areas where \UNICODE\ shines, although the
+gaps in vectors are a bad thing. One thing that I decided early in the \MKIV\
+math development is that all should fit into the same model: it makes no sense to
+cripple a whole system because of a few exceptions.
+
+Users expect their digits to be rendered upright and letters to be rendered with
+italic shapes, but use regular \ASCII\ input. This means that we need to relocate
+the letters to the relevant alphabet in \UNICODE. In \CONTEXT\ this happens as
+part of several analysis steps that more or less are the same as the axis
+mentioned. In addition there is collapsing, remapping, italic correction,
+boldening, checking, intercepting of special input, and more going on. Currently
+there are (depending on what gets enabled) some 10 to 15 manipulation passes over
+the list and there will be more.
+
+So how does the situation compare to the old one? I think we can safely say that
+we're better off now and that \LUATEX\ behaves quite okay. There is not much that
+can be improved, apart from more complete fonts (especially bold). A nice bonus
+of \LUATEX\ is that math characters can be used in text mode as well (given that
+the current font provides them).
+
+It will be clear that by following this route we moved far away from the \MKII\
+approach and the dependency on \LUA\ has become rather large in this case. The
+benefit is that we have rather clean code with hardly any exceptions. It came at
+the price of lots of experiments and (re)coding but I think it pays off for
+users.
+
+\stopsection
+
+\startsection[title=Bold]
+
+Bold is sort of special. There are bold symbols and some bold alphabets and that
+{\em is} basically what bold math is: just a different rendering. In a proper
+\OPENTYPE\ math fonts these bold characters are covered.
+
+Section titles or captions are often typeset bolder and when they contain math
+all of it needs to be bolder too. So, a regular italic shape becomes a bold
+italic shape but a bold shape becomes heavy. This means that we need a full blown
+bold font for that purpose. And although some are on the agenda of the font team,
+often we need to fake it. This is seldom an issue as (at least in the documents
+that I deal with) section titles are not that loaded with math.
+
+A proper implementation of such a mechanism involves two aspects: first there
+needs to be a complete bold math font with heavy bold included, and second the
+macro package must switch to bold math in a bold context. When no real bold font
+is available, some automatic mapping can take place, but that might give
+interpretation issues if bold is used in a formula. For the average highschool
+math that we render this is not an issue. Currently there are no full bold math
+fonts that have enough coverage. (The \XITS\ font, derived from \STIX, has a bold
+companion that does provide for instance bold radicals but lacks many bolder
+alphabets and symbols.)
+

+  {\mb \sqrt{x^2 + 4x}}
+\stopimath
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\blank \getbuffer \blank
+
+Here it is always a bit of a guess if bold extensibles are (already) supported so
+it's dangerous to go wild with full bold/heavy combinations unless you check
+carefully what results you get. Another aspect you need to be aware of is that
+there is an extensive fallback mechanism present. When possible a proper alphabet
+will be used, but when one is not present there is a fallback on another. This
+ensures that we get at least something.
+
+There is not much that an engine can do about it, apart from providing enough
+families to implement it. In a \TYPEONE\ universe indeed we need lots of families
+already so the traditional 16-family pool is drained soon. In \LUATEX\ we can
+have 256 families which means that additional \TYPEONE\ bases family sets are no
+issue any longer. But as in \MKIV\ we no longer follow that route, bold math can
+be set up relatively easy, given that we have a bold font. If we don't have such
+a font, we have an intermediate mode where a bold font is simulated. Keep in mind
+that this always will need checking, at least as long as don't have complete
+enough bold fonts with heavy bold included.
+
+\stopsection
+
+\startsection[title=Radicals]
+
+In most cases a \TEX\ user is not that aware of what happens in order to get a
+nicely wrapped up root on paper. In traditional \TEX\ this is an interplay
+between rather special font properties and macros. In \LUATEX\ it has become a
+bit more simple because we introduced a primitive for it. Also, in \OPENTYPE\
+fonts, the radical is provided in a somewhat more convenient way. In an
+\OPENTYPE\ math font there are some variables that control the rendering:
+
+\starttyping
+RadicalExtraAscender
+RadicalRuleThickness
+RadicalVerticalGap
+RadicalDisplayStyleVerticalGap
+\stoptyping
+
+The engine will use these to construct the symbol. The root symbols can grow in two
+dimensions: the left bit grows vertically but due to the fact that there is a slope
+involved it happens in steps using different symbols.
+
+\blank
+$ \dorecurse{10}{\rootradical{}{\blackrule[height=#1ex,depth=0pt,width=0pt]}} $
+\blank
+
+Compare this to for instance how a bracket grows:
+
+\blank
+$ \dorecurse{10}{\left[\blackrule[height=#1ex,depth=0pt,width=0pt]\right.} $
+\blank
+
+The bracket is a so|-|called vertical extensible character. It grows in steps
+using different glyphs and when we run out of variants a last resort kicks in: a
+symbol gets constructed from three pieces, a top and bottom piece and in between
+a repeated middle segment. The root symbol is also vertically extensible but
+there the change to the stretched variant is visually rather distinct. This has a
+reason: the specification cannot deal with slopes. So, in order to stretch the
+last resort, as with the bracket, goes vertical and provides a middle segment.
+
+The root can also grow horizontally; just watch this:
+
+\blank
+$ \dorecurse{10}{\rootradical{}{\blackrule[height=#1ex,depth=0pt,width=#1ex,color=gray]}} $
+\blank
+
+The font specification can handle vertical as well as horizontal extensibles but
+surprise: it cannot handle a combination. Maybe the reason is that there is only
+one such symbol: the radical. So, instead of expecting a symmetrical engine, an
+exception is made that is controlled by the mentioned variables. So, while we go
+upwards with a proper middle glyph, we go horizontal using a rule.
+
+One can argue that the traditional \TEX\ machinery is complex because it uses
+special font properties and macros, but once you start looking into the modern
+variant it becomes clear that although we can have a somewhat cleaner
+implementation, it still is a kludge. And, because rendering on paper no longer
+drives development it is not to be expected that this will change. The \TEX\
+community didn't come up with a better approach and there is no reason to believe
+that it will in the future.
+
+One of the reasons for users to use \TEX\ is control over the output: instead of
+some quick and dirty job authors can spend time on making their documents look
+the way they want. Even in these internet times with dynamic rendering, there is
+still a place for a more frozen rendering, explicitly driven by the author. But,
+that only makes sense when the author can influence the rendering, maybe even
+without bounds.
+
+So, because in \CONTEXT\ I really want to provide control, as one of the last
+components, math radicals were made configurable too. In fact, the code involved
+is not that complex because most was already in place. What is interesting is
+that when I rewrapped radicals once again I realized that instead of delegating
+something to the engine and font one could as well forget about it and do all in
+dedicated code. After all, what is a root symbol more that a variation of a
+framed bit of text. Here are some examples.
+
+\startbuffer[demo]
+$
+  y = \sqrt   { x^2 + ax + b } \quad
+  y = \sqrt[2]{ x^2 + ax + b } \quad
+  y = \sqrt[3]{ \frac{x^2 + ax + b }{c} }
+$
+\stopbuffer
+
+\typebuffer[demo]
+
+By default this gets rendered as follows:
+
+\blank \start \getbuffer[demo] \stop \blank
+
+We can change the rendering alternative to one that permits some additional
+properties (like color):
+
+\startbuffer[setup]
+\setupmathradical[sqrt][alternative=normal,color=maincolor]
+\stopbuffer
+
+\typebuffer[setup]
+
+This looks more or less the same:
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+\startbuffer[setup]
+\setupmathradical
+  [sqrt]
+  [alternative=mp,
+   color=darkgreen]
+\stopbuffer
+
+We can go a step further and instead of a font use a symbol that adapts itself:
+
+\typebuffer[setup]
+
+Now we get this:
+
+\blank \start \getbuffer[setup,demo] \stop \blank
+
+Such a variant can be more subtle, as we not only can adapt the slope
+dynamically, but also add a nice finishing touch to the end of the horizontal
+line. Take this variant:
+
+\startbuffer
+\startuniqueMPgraphic{math:radical:extra}
+  draw
+    math_radical_simple(OverlayWidth,OverlayHeight,OverlayDepth,OverlayOffset)
+    withpen pencircle
+      xscaled (2OverlayLineWidth)
+      yscaled (3OverlayLineWidth/4)
+      rotated 30
+    dashed evenly
+    withcolor OverlayLineColor ;
+\stopuniqueMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer[setup-extra]
+\setupmathradical
+  [sqrt]
+  [alternative=mp,
+   mp=math:radical:extra,
+   color=darkred]
+\stopbuffer
+
+We hook this graphic into the macro:
+
+\typebuffer[setup-extra]
+
+And this time we see a dashed line:
+
+\blank \start \getbuffer[setup-extra,demo] \stop \blank
+
+Of course one can argue about esthetics but let's face it: much ends up in print,
+also by publishers, that doesn't look pretty at all, so I tend to provide the
+author the freedom to make what he or she likes most. If someone is willing to
+spend time on typesetting (using \TEX), let's at least make it a pleasant
+experience.
+
+\blank
+$ \getbuffer[setup]\dostepwiserecurse{1}{13}{2}{\sqrt{\blackrule[height=#1ex,depth=0pt,width=#1ex,color=gray]}\quad} $
+\blank
+
+Here we see the symbol adapt. We can think of alternative symbols, for instance
+the first part becomes wider dependent on the height, but this can be made less
+prominent. Depending on user input I will provide some more variants as it's
+relatively easy to implement.
+
+Before I wrap up, let's see what exactly we have in stock deep down.
+Traditionally \TEX\ provides a \type {\surd} command which is just the root
+symbol. Then there is a macro \type {\root..\of..} that wraps the last argument
+in a root and typesets a degree as well (of given). In \CONTEXT\ we now provide
+this:
+
+\startbuffer
+$\surd x \quad \surdradical x  \quad \rootradical{3}{x} \quad \sqrt[3]{x}$
+\stopbuffer
+
+\typebuffer
+
+I don't remember ever having used the \type {\surd} command, but this is what
+it renders:
+
+\blank \noindentation \getbuffer \blank
+
+Only the last command, \type {\sqrt} is a macro defined in one of the math
+modules, the others are automatically defined from the database:
+
+\starttyping
+[0x221A] = { -- there are a few more properties set
+  unicodeslot = 0x221A,
+  description = "SQUARE ROOT",
+  adobename   = "radical",
+  category    = "sm",
+  mathspec    = {
+    { class = "root",     name = "rootradical" },
+    { class = "radical",  name = "surdradical" },
+    { class = "ordinary", name = "surd"        },
+  },
+}
+\stoptyping
+
+So we get the following definitions:

+So, are we better off? Given that a font sticks to how Cambria does it, we only
+need a minimal amount of code to implement roots. This is definitely an
+improvement at the engine level. However, in the font there are no fundamental
+differences between the traditional and more modern approach, but we've lost the
+opportunity to make a proper two||dimensional extensible. Eventually the user
+won't care as long as the macro package wraps it all up in useable macros.

+\startsection[title=Primes]
+
+Another rather disturbing issue is with primes. A prime is an accent|-|like
+symbol that as a kind of superscript is attached to a variable or function. In
+good old \TEX\ tradition this is entered as follows:
+
+\startbuffer
+$ f'(x) $ and $ f''(x) $
+\stopbuffer
+
+\typebuffer
+
+which produces: \inlinebuffer. The upright quote symbols are never used for
+anything else than primes and magically get remapped onto a prime symbol. This
+might look trivial, but there are several aspects to deal with, especially when
+using traditional fonts. In the eight|-|bit \type {lmsy10} math symbol font,
+which is derived from the original \type {cmsy10} the prime symbol looks like
+this:
+
+\startlinecorrection
+\ruledhbox{\definedfont[file:lmsy10.afm]\getnamedglyphdirect{file:lmsy10.afm}{prime}}
+\stoplinecorrection
+
+The bounding box is rather tight and the reason for this becomes clear when we put
+it alongside another character:
+
+\startlinecorrection
+$x\ruledhbox{\definedfont[file:lmsy10.afm]\getnamedglyphdirect{file:lmsy10.afm}{prime}}$
+\stoplinecorrection
+
+The prime is not only pretty large, it also sits on the baseline. It means that
+in order to make it a real prime (basically an operator pointing back to the
+preceding symbol), we need to raise it. Of course we can define a \type {\prime}
+command that takes care of this, and indeed that is what happens in plain \TEX\
+and derived formats. The more direct \type {'} input is supported by making that
+character an active character in math mode. Active characters behave like
+commands and in this case the \type {\prime} command.
+
+In the \OPENTYPE\ latin modern fonts the prime (\type{U+2032}) looks like this:
+
+\startlinecorrection
+$x\ruledhbox{\definedfont[file:latin-modernmath]\utfchar{0x2032}}$
+\stoplinecorrection
+
+So here we have an already raised and also smaller prime symbol. And, because we
+also have double (\type{U+2033}) and triple primes (\type{U+2034}) a few more
+characters are available
+
+\startlinecorrection
+$x\ruledhbox{\definedfont[file:latin-modernmath]\utfchar{0x2032}}$
+$x\ruledhbox{\definedfont[file:latin-modernmath]\utfchar{0x2033}}$
+$x\ruledhbox{\definedfont[file:latin-modernmath]\utfchar{0x2034}}$
+\stoplinecorrection
+
+In the traditional approach these second and third order primes are built from
+the first order primes. And this introduces, in addition to the raising, another
+complexity: the \type {\prime} command has to look ahead and intercept future
+primes. And as there can also be a following raised symbol (or number) it needs
+to take a superscript trigger into account as well. So, let's look at some
+possible input:
+
+\def\ShowPrime#1{\NC \type{$#1$} \NC $#1$ \NC \NR}
+
+\starttabulate[|||]
+\ShowPrime{f'(x)}
+\ShowPrime{f''(x)}
+\ShowPrime{f'''(x)}
+\ShowPrime{f\prime^2}
+\ShowPrime{f\prime\prime^2}
+\ShowPrime{f\prime\prime\prime^2}
+\ShowPrime{f'\prime'^2}
+\ShowPrime{f^'(x)}
+\ShowPrime{f'^2}
+\ShowPrime{f{\prime}^2}
+\stoptabulate
+
+Now imagine that you have this big prime character sitting on the baseline and
+you need to turn \type {'''} into a a triple prime, but don't want \type {^'} to
+be double raised, while on the other hand \type {^2} should be. This is of course
+doable with some macro juggling but how about supporting traditional fonts in
+combination with \OPENTYPE, where the primes are already raised.
+
+When we started with \LUATEX\ and \CONTEXT\ \MKIV, one of the first decisions I
+made was to go \UNICODE\ math and drop eight|-|bit. In order to compensate for
+the lack of fonts, a mechanism was provided to construct virtual \UNICODE\ math
+fonts, as a prelude to the lm/gyre \OPENTYPE\ math fonts. In the meantime we have
+these fonts and the virtual variants are only kept as historic reference and for
+further experiments.
+
+As a starter I wrote a variant of the traditional \CONTEXT\ \type {\prime}
+command that could recognize somehow if it was dealing with a \TYPEONE\ or
+\OPENTYPE\ font. As a consequence it also had the traditional raise and look
+ahead mess on board. However, there was also some delegation to the \LUA\
+enhanced math support code, so the macro was not that complex. When the real
+\OPENTYPE\ math fonts showed up the macro was dropped and the virtual fonts were
+adapted to the raised|-|by|-|default situation, which in itself was somewhat
+complicated by the fact that a smaller symbol had to be used, i.e.\ some more
+information about the current set of defined math sizes has to be passed around.
+\footnote {The actual solution for this qualifies as a dirty trick so we are not
+freed from tricks yet.}
+
+Anyhow, the current implementation is rather clean and supports collapsing of
+combinations rather well. There are four prime symbols but only three reverse
+prime symbols. If needed I can provide a virtual \typ {REVERSED TRIPLE PRIME} if
+needed, but I guess it's not needed.

+
+Of course no one will use this ligature approach but I've learned to be prepared
+as it wouldn't be the first time when we encounter input that is cut and paste
+from someplace or clicked|-|till|-|it|-|looks|-|okay.
+
+There is one big complication and that is that where in \TEX\ there is only one
+big prime that gets raised and repeated in case of multiple primes, in \OPENTYPE\
+the primes are already raised. They are in fact not supposed to be superscripted,
+as they are already. In plain \TEX\ the prime is entered using an upright single
+quote and that one is made active: it is in fact a macro. That macro looks ahead
+and intercepts following primes as well as subscripts. In the end, a superscript
+(the prime) and optional subscripts are attached to the preceding symbol. If we
+want to benefit from the \UNICODE\ primes as well as support collapsing, such a
+macro quickly becomes messy. Therefore, in \MKIV\ the optional subscript is
+handled in the collapser. We cheat a bit by relocating super- and subscripts and
+at the same time remap the primes to virtual characters that are smashed to a
+smaller height, lowered to the baseline, and eventually superscripted. Indeed, it
+sounds somewhat complex and it is. In a next version I will also provide ways to
+influence the size as one might want larger of smaller primes to show up. This is
+one case where the traditional \TEX\ fonts have a benefit as the primes are
+superscriptable characters, but we have to admit that the \UNICODE\ and
+\OPENTYPE\ approach is conceptually more correct. The only way out of this is to
+have a primitive operation for primes just as we have for radicals but that also
+has some drawbacks. Eventually I might come up with a cleaner solution for this
+dilemma.
+
+Let us summarize the situation and solution used in \MKIV\ now:
+
+\startitemize[packed]
+    \startitem
+        When (still) using the virtual \UNICODE\ math fonts, we construct a
+        virtual glyph that has properties similar to proper \OPENTYPE\ math
+        fonts.
+    \stopitem
+    \startitem
+        We collapse a sequence of primes into proper double and triple
+        primes.
+    \stopitem
+    \startitem
+        We unraise primes so that users who (for some reason) superscript them
+        (maybe because they still assume big ones sitting on the baseline) get
+        the desired outcome.
+    \stopitem
+    \startitem
+        We accept mixtures of \type {'} and \type {\prime}.
+    \stopitem
+\stopitemize
+
+We can do this because in \CONTEXT\ \MKIV\ we don't care too much about exact
+visual compatibility as long as we can make users happy with clean mechanisms.
+So, this is one of the situations where the new situation is better, thanks to on
+the one hand the way primes are provided in fonts, and on the other hand the
+enhanced math machinery in \MKIV.
+
+\stopsection
+
+\startsection[title=Accents]
+
+There are a few special character types in math and accents are one of them.
+Personally I think that the term accent is somewhat debatable but as they are
+symbols drawn on top of or below something we can stick to that description for
+the moment. In addition to some regular fixed width variants, we have adaptive
+versions: \type {\hat} as well as \type {\widehat} and more.
+
+\startlinecorrection
+\dorecurse{6}{$\widehat{\blackrule[width=#1ex,color=gray]}$ }
+\stoplinecorrection
+
+I have no clue if wider variants are needed but such a partial coverage
+definitely looks weird. So, as an escape users can kick in their own code. After
+all, who says that a user cannot come up with a new kind of math. The following
+example demonstrates how this is done:
+
+\startbuffer
+\startMPextensions
+    vardef math_ornament_hat(expr w,h,d,o,l) text t =
+        image (
+            fill
+                (w/2,10l) -- (w + o/2,o/2) --
+                (w/2, 7l) -- (  - o/2,o/2) --
+                cycle shifted (0,h-o) t ;
+            setbounds
+                currentpicture
+            to
+                unitsquare xysized(w,h) enlarged (o/2,0)
+        )
+    enddef ;
+\stopMPextensions
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This defines a hat|-|like symbol. Once the sources of the math font project are
+published I can imagine that an ambitious user defines a whole set of proper
+shapes. Next we define an adaptive instance:
+
+\startbuffer
+\startuniqueMPgraphic{math:ornament:hat}
+    draw
+        math_ornament_hat(
+            OverlayWidth,
+            OverlayHeight,
+            OverlayDepth,
+            OverlayOffset,
+            OverlayLineWidth
+        )
+    withpen
+        pencircle
+            xscaled (2OverlayLineWidth)
+            yscaled (3OverlayLineWidth/4)
+            rotated 30
+    withcolor
+        OverlayLineColor ;
+\stopuniqueMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Last we define a symbol:
+
+\startbuffer
+\definemathornament [mathhat] [mp=math:ornament:hat,color=darkred]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+And use it as \type {\mathhat{...}}:
+
+\startlinecorrection
+\dorecurse{8}{$\mathhat{\blackrule[width=#1ex,color=gray]}$ }
+\stoplinecorrection
+
+Of course this completely bypasses the accent handler and in fact even writing
+the normal stepwise one is not that hard to do in macros. But, there is a
+built||in mechanism that helps us for those cases and it can even deal with font
+based stretched alternatives of which there are a few: curly braces, brackets and
+parentheses. The reason that these can stretch is that they don't have slopes and
+therefore can be constructed out of pieces: in the case of a curly brace we have
+4 snippets: begin, end, middle and repeated rules, and in the case of braces and
+brackets 3 snippets will do. But, if we really want we can use \METAPOST\ code
+similar to the code shown above to get a nicer outcome.
+
+There are in good \TEX\ tradition four accents that can also stretch
+horizontally: bar, brace, parenthesis and bracket. When using fonts such an
+accent looks like this:
+
+% \setupmathstackers[vfenced][color=darkyellow]
+
+\startbuffer
+$ \overbrace{a+b+c+d} \quad \underbrace{a+b+c+d} \quad \doublebrace{a+b+c+d} $
+\stopbuffer
+
+\blank \start \setupmathstackers[vfenced][color=darkyellow] \getbuffer \stop \blank
+
+this is coded like:
+
+\typebuffer
+
+As with radicals, for more fancy math you can plug in \METAPOST\ variants. Of
+course this kind of rendering should fit into the layout of the document but I
+can imagine that for schoolbooks this makes sense.
+
+\startbuffer[setup]
+\useMPlibrary[mat]
+
+\setupmathstackers
+  [vfenced]
+  [color=darkred,
+   alternative=mp]
+\stopbuffer
+
+\typebuffer[setup]
+
+Applied in an example we get:
+
+\startbuffer[demo]
+$\overbracket{a+b+c+d} \quad \underbracket{a+b+c+d} \quad \doublebracket{a+b+c+d}$ \blank
+$\overparent {a+b+c+d} \quad \underparent {a+b+c+d} \quad \doubleparent {a+b+c+d}$ \blank
+$\overbrace  {a+b+c+d} \quad \underbrace  {a+b+c+d} \quad \doublebrace  {a+b+c+d}$ \blank
+$\overbar    {a+b+c+d} \quad \underbar    {a+b+c+d} \quad \doublebar    {a+b+c+d}$ \blank
+\stopbuffer
+
+\start \getbuffer[setup] \startlines\getbuffer[demo]\stoplines \stop
+
+This kind of magic is partly possible because in \LUATEX\ (and therefore \MKIV)
+we can control matters a bit better. And of course the fact that we have
+\METAPOST\ embedded means that the impact of using graphics is not that large.
+
+We used the term \quote {stackers} in the setup command so although these are
+officially accents, in \CONTEXT\ we implement them as instances of a more generic
+mechanism: things stacked on top of each other. We will discuss these in the next
+section.
+
+\stopsection
+
+\startsection[title=Stackers]
+
+In plain \TEX\ and derived work you will find lots of arrow builders. In most
+cases we're talking of a combination of one or more single or double arrow heads
+combined with a rule. In any case it is something that is not so much font driven
+but macro magic. Optionally there can be text before and|/|or after as well as
+text above and|/|or below them. The later is for instance the case in chemistry.
+This text is either math or upright properly kerned and spaced non||mathematical
+text so we're talking of some mixed math and text usage. The size is normally
+somewhat smaller.
+
+Arrows can also go on top or below regular math so in the end we end up with
+several cases:
+
+\startitemize[packed]
+    \startitem
+        Something stretchable on top of or centered around the baseline, optionally
+        with text above or below.
+    \stopitem
+    \startitem
+        Something stretchable on top of a running (piece of) text or math.
+    \stopitem
+    \startitem
+        Something stretchable below a running (piece of) text or math.
+    \stopitem
+    \startitem
+        Something stretchable on top as well as below a running (piece of) text
+        or math.
+    \stopitem
+\stopitemize
+
+These have in common that the symbol gets stretched. In fact the last three cases
+are quite similar to accents but in traditional \TEX\ and its fonts arrows and
+alike never made it to accents. One reason is probably that because a macro
+language was available and because fonts were limited, it was rather easy to use
+rules to extend an arrowhead.
+
+In \CONTEXT\ this kind of vertically stacked stretchable material is implemented
+as stackers. In the chapter \type {mathstackers} of \type {about.pdf} you can
+read more about the details so here I stick to a short summary to illustrate what
+we're dealing with. Say that you want an arrow that stretches over a given width.
+
+\starttyping
+\hbox to 4cm{\leftarrowfill}
+\stoptyping
+
+In traditional \TEX\ with traditional fonts the definition of this arrow
+looks as follows:
+
+\starttyping
+\def\leftarrowfill {$
+  \mathsurround=0pt
+  \mathord{\mathchar"2190}
+  \mkern-7mu
+  \cleaders
+   \hbox {$
+     \mkern-2mu
+     \mathchoice
+      {\setbox0\hbox{$\displaystyle     -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\textstyle        -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\scriptstyle      -$}\ht0=0pt\dp0=0pt\box0}
+      {\setbox0\hbox{$\scriptscriptstyle-$}\ht0=0pt\dp0=0pt\box0}
+     \mkern-2mu
+    $}
+   \hfill
+  \mkern-7mu
+  \mathchoice
+   {\setbox0\hbox{$\displaystyle     -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\textstyle        -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\scriptstyle      -$}\ht0=0pt\dp0=0pt\box0}
+   {\setbox0\hbox{$\scriptscriptstyle-$}\ht0=0pt\dp0=0pt\box0}
+$}
+\stoptyping
+
+When using \TYPEONE\ fonts we don't use a \type {\mathchar} but
+more something like this:
+
+\starttyping
+\leftarrow = \mathchardef\leftarrow="3220
+\stoptyping
+
+What we see in this macro is a left arrow head at the start and as minus sign at
+the end. In between the \type {\cleaders} will take care of filling up the
+available hsize with more minus signs. The overlap is needed in order to avoid
+gaps due to rounding in the renderer and also obscures the rounded caps of the
+used minus sign.
+
+The minus sign is used because it magically connects well to the arrow head. This
+is of course a property of the design but even then you can consider it a dirty
+trick. We don't specify a width here as this macro adapts itself to the current
+width due to the leader. But if we do know the width an easier approach becomes
+possible. Take this combination of a left and right arrow on top of each other:
+
+\starttyping
+\mathstylehbox{\Umathaccent\fam\zerocount"21C4{\hskip4cm}}
+\stoptyping
+
+The \type {\mathstylehbox} macro is a \CONTEXT\ helper. When we take a closer
+look at the result (scaled up a bit) we see again snippets being used: \footnote
+{We cheat a bit here: as we use \XITS\ in this document, and that font doesn't
+yet provide this magic we switch temporarily to the Pagella font}.
+
+\startlinecorrection
+\showglyphs \switchtobodyfont[pagella]
+\scale[width=\textwidth]{\mathstylehbox{\Umathaccent\fam\zerocount"21C4{\hskip4cm}}}
+\stoplinecorrection
+
+But this time the engine itself deals with the filling. Unfortunately for the
+accent approach to work we need to specify the width. Given how these arrows are
+used, this is no problem: because we often put text on top and|/|or below, we
+need to do some packaging and therefore know the dimensions, but a generic
+alternative would be nice. This is why for \LUATEX\ we have on the low priority
+agenda:
+
+\starttyping
+\leaders"2190\hfill
+\stoptyping
+
+or a similar primitive. This way we can let the engine do some work and keep
+macros simple. Normally \type {\leaders} delegate part of repeating to the
+backend but in the case of math it has to be part of constructing the formula
+because the extensible constructor has to be used.
+
+If you've looked into the \LUATEX\ manual you might have noticed that there is a
+new primitive that permits this:
+
+\starttyping
+\mathstylehbox{\Uoverdelimiter\fam"21C4{\hskip4cm}}
+\stoptyping
+
+However, it is hardly useable for our purpose for several reasons. First of all,
+when the argument is narrower than the smallest possible delimiter both get left
+aligned, so the delimiter sticks out (this can be considered a bug). But also,
+the placement is influenced by a couple of parameters that we then need to force
+to zero values, which might interfere. Another property of this mechanism is that
+the style is influenced and so we need to mess more with that. These are enough
+reasons to ignore this extension for a while. Maybe at some point, when really
+needed, I will write a proper wrapper for this primitive.
+
+When we started with \MKIV\ we stuck with the leaders approach for a while if
+only because there was no real need to redefine the old macros. But after a while
+one starts wondering if this is still the way to go, especially when
+reimplementing the chemistry macros didn't lead to nicer looking code. Part of
+the problem was that putting two arrows on top of each other where each one goes
+into another direction gave issues due to the fact that we don't have the right
+snippets to do it nicely. A way out was to create virtual characters for
+combinations of begin and end snippets as well as middle pieces, construct a
+proper virtual extensible and use the \LUATEX\ extensible constructor. Although
+we still have a character that gets built out of snippets, at least the begin and
+end snippet indicate that we have to do with one codepoint, contrary to two
+independent stacked arrows.
+
+This was also the moment that I realized that it was somewhat weird that
+\OPENTYPE\ math fonts didn't have that kind of support. After discussing this
+with Bogus{\l}aw Jackowski of the math font project we decided that it made sense
+to add proper native extensibles to the upcoming math fonts. Of course I still
+had to support other math fonts but at least we had a conceptually clean example
+font now. So, from that moment on the implementation used extensibles when
+possible and falls back on the fake approach when needed.
+
+In \CONTEXT\ all these vertically stacked items are now handled by the math
+stacker subsystem, including a decent set of configuration options. As said, the
+symbols that need to stretch currently use the accent primitives which is okay
+but somewhat messy because that mechanism is hard to control (after all it wants
+to put stuff on top or below something). For (mostly) chemistry we can put text
+on top or below arrows and control offsets of the text as well as the axis of the
+arrows. We can use color and set the style. In addition there are constructs
+where there is text in the middle and arrows (or other symbols that need to
+adapt) on top or at the bottom.
+
+Many arrows come in sizes. For instance there are two sizes of right pointing
+arrows as well as stretched variants, and use as top and bottom accents.

+
+The first two arrows are just characters. The boxed ones are extensibles using
+leaders that build the arrow from snippets (a hack till we have proper character
+leaders) and the last two are implemented by abusing the accent mechanism and
+thereby use the native extensibles of the first character.
+
+The problem here is in names and standards. The first characters have a fixed
+size while the later are composed. The short ones have the extensibles and can
+therefore be used as accents (or when supported as character leader). However
+from the user's perspective, the distinction between the two \UNICODE\ characters
+might be less clear, not so much when they are used as character, but when used
+on top of or below something. As a coincidence, while writing this section, a
+colleague dropped a snippet of \MATHML\ on my desk:
+
+\starttyping
+<m:math>
+  <m:mrow>
+    <m:mover accent='true'>
+      <m:mrow>
+        <m:mi>A</m:mi>
+        <m:mi>S</m:mi>
+      </m:mrow>
+      <m:mo stretchy='true'>→</m:mo>
+    </m:mover>
+  </m:mrow>
+</m:math>
+\stoptyping
+
+However, instead of {<m:mo>→</m:mo>} there was used \type
+{<m:mo>&xrarr;</m:mo>} and that entity is the long arrow. As is often the case in
+\MATHML\ the rendering is supposed to be quite tolerant and here both should
+stretch over the row. When a \TEX\ user renders his or her source and sees
+something wrong, the search for what character or command should be used instead
+starts. A \MATHML\ user probably just expects things to work. This means that in
+a system like \CONTEXT\ there will always be hacks and kludges to deal with such
+matters. It is again one of these areas where optimally the \TEX\ community could
+have influenced proper and systematic coding, but it didn't happen. So, no matter
+now good we make an engine or macro package, we always need to be prepared to
+adapt to what users expect. Let's face it: it's not that trivial to explain why
+one should favor one or the other arrow as accent: the more it has to cover, the
+longer it gets and the more we think of long arrows, but adding a whole bunch of
+\type {\longrightarrow...} commands to \CONTEXT\ makes no sense.
+
+Nevertheless, we might eventually provide more \MATHML\ compliant commands at the
+\TEX\ end. Just consider the following \MATHML\ snippets: \footnote {These
+examples are variations on what we run into in Dutch school math (age 14\endash
+16).}

+When no arrow (or other stretchable character) is used, we still need to put one

+
+We have been supporting \MATHML\ in \CONTEXT\ for a long time and will continue
+doing it. I will probably reimplement the converter (given a good reason) using
+more recent subsystems. It doesn't change the fact that in order to support it,
+we need to have some robust analytical support macros (functions) to deal with
+situations as mentioned. The \TEX\ engine is not made for that but in the
+meantime it has become more easy thanks to a combination of \TEX, \LUA\ and data
+tables. Consistent availability of extensibles (either or not virtual) helps too.
+
+Among the conclusions we can draw is that quite a lot of development (font as
+well as engine) is driven by what we have had for many years. A generic
+multi||dimensional glyph handler could have covered all odd cases that used to be
+done with macros but for historic reasons we could still be stuck with several
+slightly different and overlapping mechanisms. Nevertheless we can help macro
+writers by providing for instance leaders that accept characters as well in which
+case in math mode extensibles can be used.
+
+\stopsection
+
+\startsection[title=Fences]
+
+Fences are symbols that are put left and|/|or right of a formula. They adapt
+their height and depth to the content they surround, so they are vertical
+extensibles. Users tend to minimize their coding but this is probably not a good
+idea with fences as there is some magic involved. For instance, \TEX\ always
+wants a matching left and right fence, even if one is a phantom. So you will
+normally have something like this:
+
+\starttyping
+\left\lparent x \right\rparent
+\stoptyping
+
+and when you don't want one of them you use a period:
+
+\starttyping
+\left\lparent x \right.
+\stoptyping
+
+The question is, can we make the users live easier by magically turning braces,
+brackets and parentheses etc.\ into growing ones. As with much in \MKIV, it could
+be that \LUA\ can be of help. However, look at the following cases:
+
+\startbuffer
+\startformula (x) \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This internally becomes something like this:
+
+\starttyping
+open  noad : nucleus : mathchar : U+00028
+ord   noad : nucleus : mathchar : U+00078
+close noad : nucleus : mathchar : U+00029
+\stoptyping
+
+We get a linked list of three so|-|called noads where each nucleus is a math
+character. In addition to a nucleus there can be super- and subscripts.
+
+\startbuffer
+\startformula \mathinner { (x) } \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\starttyping
+inner noad : nucleus : submlist :
+  open  noad : nucleus : mathchar : U+00028
+  ord   noad : nucleus : mathchar : U+00078
+  close noad : nucleus : mathchar : U+00029
+\stoptyping
+
+This is still simple, although the inner primitive results in three extra levels.
+
+\startbuffer
+\startformula \left( x \right) \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Now it becomes more complex, although we can still quite well recognize the
+input. The question is: how easily can we translate the previous examples into
+this structure.
+
+\starttyping
+inner noad : nucleus : submlist :
+  left  fence : delim   : U+00028
+  ord   noad  : nucleus : mathchar U+00078
+  right fence : delim   : U+00029
+\stoptyping
+
+\startbuffer
+\startformula ||x|| \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Again, we can recognize the sequence in the input:
+
+\starttyping
+ord noad : nucleus : mathchar : U+0007C
+ord noad : nucleus : mathchar : U+0007C
+ord noad : nucleus : mathchar : U+00078
+ord noad : nucleus : mathchar : U+0007C
+ord noad : nucleus : mathchar : U+0007C
+\stoptyping
+
+Here we would have to collapse the two bars into one. Now, say that we manage to
+do this, even if it will cost a lot of code to check all border cases, then how
+about this?
+
+\startbuffer
+\startformula \left|| x \right|| \stopformula
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\starttyping
+inner noad : nucleus : submlist noad :
+  left  fence : delim : U+00028
+  ord   noad  : nucleus : mathchar : U+0007C
+  ord   noad  : nucleus : mathchar : U+00078
+  right fence : delim : U+00029
+ord noad : nucleus : mathchar : U+0007C
+\stoptyping
+
+This time we have to look over the sublist and compare the last fence with the
+character following the sublist. If you keep in mind that there can be all kind
+of nodes in between, like glue, and that we can have multiple nested fences, it
+will be clear that this is a no|-|go. Maybe for simple cases it could work out
+but for a bit more complex math one ends up in constantly fighting asymmetrical
+input at the \LUA\ end and occasionally fighting the heuristics at the \TEX\ end.
+
+It is for this reason that we provide a mechanism that users can use to avoid the
+primitives \type {\left} and \type {\right}.
+
+\startbuffer
+\setupmathfences
+  [color=red]
+
+\definemathfence
+  [fancybracket]
+  [bracket]
+  [command=yes,

+  a \fenced[bar]      {\frac{1}{b}} c \qquad

+  a \fenced[bracket]  {\frac{1}{b}} c \qquad
+  a \fancybracket     {\frac{1}{b}} c
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+So, you can either use a generic instance of fences (\type {\fenced}) or you
+can define your own commands. There can be several classes of fences and they
+can inherit and be cloned.
+
+\getbuffer
+
+As a bonus \CONTEXT\ provides a few wrappers:
+
+\startbuffer
+\startformula
+\Lparent    \frac{1}{a} \Rparent    \quad
+\Lbracket   \frac{1}{b} \Rbracket   \quad
+\Lbrace     \frac{1}{c} \Rbrace     \quad
+\Langle     \frac{1}{d} \Rangle     \quad
+\Lbar       \frac{1}{e} \Rbar       \quad
+\Ldoublebar \frac{1}{f} \Rdoublebar \quad
+\Ltriplebar \frac{1}{f} \Rtriplebar \quad
+\Lbracket   \frac{1}{g} \Rparent    \quad
+\Langle     \frac{1}{h} \Rnothing
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+which gives:
+
+\getbuffer
+
+For bars, the same applies as for primes: we collapse them into proper \UNICODE\
+characters when applicable:
+
+\def\Nsbar{\ruledmbox{\singleverticalbar}}
+\def\Ndbar{\ruledmbox{\doubleverticalbar}}
+\def\Ntbar{\ruledmbox{\tripleverticalbar}}

+\stoptabulate
+
+The question is always: to what extent do users want to structure their input.
+For instance, you can define this:
+
+\startbuffer
+\definemathfence [weirdrange] [left="0028,right="005D]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+and use it as:
+
+\startbuffer
+$ (a,b] = \fenced[weirdrange]{a,b}$
+\stopbuffer
+
+\typebuffer
+
+This gives \inlinebuffer\ and unless you want to apply color or use specific
+features there is nothing wrong with the direct way. Interesting is that the
+complications are seldom in regular \TEX\ input, but \MATHML\ is a different
+story. There is an \type {mfenced} element but as users can also use the more
+direct route, a bit more checking is needed in order to make sure that we have
+matching open and close symbols. For reasons mentioned before we cannot delegate
+this to \LUA\ but have to use special versions of the \type {\left} and \type
+{\right} commands.
+
+One complication of making a nice mechanism for this is that we cannot use the
+direct characters. For instance curly braces are also used for grouping and the
+less and equal signs serve different purposes. So, no matter what we come up
+with, these cases remain special. However, in \CONTEXT\ the following is valid:
+
+\startbuffer
+\setupmathfences[color=darkgreen]
+\setupmathfences[mirrored][color=darkred]
+
+\startformula
+\left { \frac{1}{a} \right } \quad
+\left [ \frac{1}{b} \right ] \quad
+\left ( \frac{1}{c} \right ) \quad
+\left < \frac{1}{d} \right > \quad
+\left ⟨ \frac{1}{d} \right ⟩ \quad
+\left | \frac{1}{e} \right | \quad
+\left ⟪ \frac{1}{e} \right ⟫ \quad
+\left ⟫ \frac{1}{e} \right ⟪ \quad
+\left [ \frac{1}{d} \right [ \quad
+\left ] \frac{1}{d} \right [ \quad
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+In the background mapping onto the mentioned left and right commands happens so
+we do get color support as well. And, it doesn't look that bad in your document
+source either. Of course other combinations are also possible.
+
+\start \getbuffer \stop
+
+As there are many ways to get fences and users can come from other macro packages
+(or use them mixed) we support them all as well as possible.
+
+\startbuffer
+\left (       \frac{1}{x} \right )       =

+
+Unfortunately \UNICODE\ math doesn't free us from some annoyances with respect to
+paired fences. On the one hand coding math is a symbolic, abstract matter: a left
+parenthesis opens something and a right one closes something. The same is true
+for brackets and braces. However, the bar is used for left and right fencing as
+well as separating pieces of a formula (e.g.\ in conditions). Because
+traditionally these left and right bars were purely vertical with no slope, or
+hooks, or other thingies attached, in \UNICODE\ there is only one slot for it.
+Where paired fences can play a role in analyzing content, bars are rather useless
+for that. It also means that when coding a formula one cannot rely on the bar
+symbol to determine a left or right property. Normally this is no problem as we
+can use symbolic names (that include the \type {\left} or \type {\right}
+directive) but for instance in rendering \MATHML\ it demands some fuzzy logic to
+be applied. It would have been nice to have code points for the three cases.

+Believe me: we run into any combination of these bars and parentheses. And we're
+no longer surprised to see code like this (generated from applications):

+\stoptyping
+
+Here the bar sits in its own group, so what is it? A lone left, right or middle
+symbol, meant to stretch with the surroundings or not?
+
+To summarize: there is no real difference (or progress) with respect to fences in
+\LUATEX\ compared to traditional \TEX. We still need matching \type {\left} and
+\type {\right} usage and catching mismatches automatically is hard. By adding
+some hooks at the \TEX\ end we can easily check for a missing \type {\right} but
+a missing \type {\left} needs a two|-|pass approach. Maybe some day in \CONTEXT\
+we will end up with multipass math processing and then I'll look into this again.

+The first time I saw right|-|to|-|left math was at a Dante and later at a TUG
+meeting hosted in Morocco where Azzeddine Lazrek again demonstrated
+right|-|to|-|left math. It was only after Khaled Hosny added some support to the
+\XITS\ font that I came to supporting it in \CONTEXT. Apart from some
+housekeeping nothing special is needed: the engine is ready for it. Of course it
+would be nice to extend the lm and gyre fonts as well but currently it's not on
+the agenda. I expect to add some more control and features in the future, if only
+because it is a nice visual experience. And writing code for such features is
+kind of fun.
+
+As this is about as complex as it can gets, it makes a nice example of how we
+control math font definitions, so let's see how we can define a \XITS\ use case.
+Because we have a bold (heavy) font too, we define that as well. First we define
+the two fonts.

+
+There can be many more entries but here the most important one is the \type
+{alternates} table. It defines the additional styles available in the font.
+Alternaties are chosen using commands like
+
+\starttyping
+\mathalternate{cal}\cal
+\stoptyping
+
+and of course shortcuts for this can be defined.
+
+Of course there is more than math, so we define a serif collection too:
+
+\starttyping
+\starttypescript [serif] [xits] [name]
+  \setups[font:fallback:serif]
+  \definefontsynonym[Serif]          [xits-regular.otf]    [features=default]
+  \definefontsynonym[SerifBold]      [xits-bold.otf]       [features=default]
+  \definefontsynonym[SerifItalic]    [xits-italic.otf]     [features=default]
+  \definefontsynonym[SerifBoldItalic][xits-bolditalic.otf] [features=default]
+\stoptypescript
+\stoptyping
+
+If needed you can redefine the \type {default} feature before this typescript is
+used. Once we have the fonts defined we can start building a typeface:
+
+\starttyping
+\starttypescript[xits]
+  \definetypeface [xits] [rm] [serif] [xits]   [default]
+  \definetypeface [xits] [ss] [sans]  [heros]  [default] [rscale=0.9]
+  \definetypeface [xits] [tt] [mono]  [modern] [default] [rscale=1.05]
+  \definetypeface [xits] [mm] [math]  [xits]   [default]
+\stoptypescript
+\stoptyping
+
+We can now switch to this typeface with:
+
+\starttyping
+\setupbodyfont[xits]
+\stoptyping
+
+But, as we wanted bidirectional math, something more is needed. Instead of the
+two fonts we define six. We could have a more abstract reference to the \XITS\
+fonts but in cases like this we prefer file names because then at least we can be
+sure that we get what we ask for.
+
+\starttypescript [math] [xits,xitsbidi] [name]
+  \loadfontgoodies[xits-math]
+  \definefontsynonym[MathRoman]       [xits-math.otf]    [features=math\mathsizesuffix,goodies=xits-math]
+  \definefontsynonym[MathRomanL2R]    [xits-math.otf]    [features=math\mathsizesuffix-l2r,goodies=xits-math]
+  \definefontsynonym[MathRomanR2L]    [xits-math.otf]    [features=math\mathsizesuffix-r2l,goodies=xits-math]

+  \definefontsynonym[MathRomanBoldR2L][xits-mathbold.otf][features=math\mathsizesuffix-r2l,goodies=xits-math]
+\stoptypescript
+
+So, we use the same fonts several times but apply different features to them.
+This time the typeface definition explicitly turns on both directions. When we
+don't do that we get only left to right support, which is of course more
+efficient in terms of font usage.
+
+\starttypescript[xitsbidi]
+  \definetypeface [xitsbidi] [rm] [serif] [xits]     [default]
+  \definetypeface [xitsbidi] [ss] [sans]  [heros]    [default] [rscale=0.9]
+  \definetypeface [xitsbidi] [tt] [mono]  [modern]   [default] [rscale=1.05]
+  \definetypeface [xitsbidi] [mm] [math]  [xitsbidi] [default] [direction=both]
+\stoptypescript
+
+We can now switch to the bidirectional typeface with:
+
+\starttyping
+\setupbodyfont[xitsbidi]
+\stoptyping
+
+However, in order to get bidirectional math indeed, we need to turn it on.
+
+\starttyping
+\setupmathematics[align=r2l]
+\stoptyping
+
+You might have wondered what this special way of defining the features using
+\type {\mathsizesuffix} means? The value of this macro is set at font definition
+time, and can be one of three values: \type {text}, \type {script} and \type
+{scriptscript}. At this moment the features are defined as follows:
+
+\starttyping
+\definefontfeature
+  [mathematics]
+  [mode=base,
+   liga=yes,
+   kern=yes,
+   tlig=yes,
+   trep=yes,
+   mathalternates=yes,
+   mathitalics=yes,
+ % nomathitalics=yes, % don't pass to tex
+   language=dflt,
+   script=math]
+\stoptyping
+
+From this we clone:
+
+\starttyping
+\definefontfeature
+  [mathematics-l2r]
+  [mathematics]
+  []
+
+\definefontfeature
+  [mathematics-r2l]
+  [mathematics]
+  [language=ara,
+   rtlm=yes,
+   locl=yes]
+\stoptyping
+
+Watch how we enable two specific features, where \type {rtlm} is a \XITS|-|specific
+one. The eventually used features are defined as follows.
+
+\starttyping
+\definefontfeature[math-text]            [mathematics]    [ssty=no]
+\definefontfeature[math-script]          [mathematics]    [ssty=1,mathsize=yes]
+\definefontfeature[math-scriptscript]    [mathematics]    [ssty=2,mathsize=yes]
+
+\definefontfeature[math-text-l2r]        [mathematics-l2r][ssty=no]
+\definefontfeature[math-script-l2r]      [mathematics-l2r][ssty=1,mathsize=yes]
+\definefontfeature[math-scriptscript-l2r][mathematics-l2r][ssty=2,mathsize=yes]
+
+\definefontfeature[math-text-r2l]        [mathematics-r2l][ssty=no]
+\definefontfeature[math-script-r2l]      [mathematics-r2l][ssty=1,mathsize=yes]
+\definefontfeature[math-scriptscript-r2l][mathematics-r2l][ssty=2,mathsize=yes]
+\stoptyping
+
+Even if it is relatively simple to do, it makes no sense to build complex mixed
+mode system, so currently we have to decide before we typeset a formula:
+
+\startbuffer
+\setupmathematics[align=l2r]
+\startformula
+       \sqrt{x^2\over 4x}  \qquad
+  {\bf \sqrt{x^2\over 4x}} \qquad
+  {\mb \sqrt{x^2\over 4x}}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+This gives a left to right formula:
+
+\getbuffer
+
+\startbuffer
+\setupmathematics[align=r2l]
+\startformula
+       \sqrt{ف^2\over 4ب}  \qquad
+  {\bf \sqrt{ف^2\over 4ب}} \qquad
+  {\mb \sqrt{ف^2\over 4ب}}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+And here we get an Arabic formula, where the quality of course is determined
+by the completeness of the font.
+
+\start
+\switchtobodyfont[xitsbidi]
+\getbuffer
+\stop
+
+The bold font has a partial bold implementation so unless I implement a more
+complex pseudo|-|bold mechanism you should not expect results. Because we have no
+official Arabic math alphabets they are not seen by the \CONTEXT\ \MKIV\
+analyzers that normally take care of this. It's all a matter of demand and supply
+(combined with a dose of motivation). For instance while a base size might be
+covered, the extensibles might be missing.
+
+About the time of writing this another variation was requested at the mailing
+list. For Persian math we keep the direction from left to right but the digits
+have to be in an Arabic font. We cannot use the bidirectional handler for this so
+we need to swap regular and bold digits in another way. We can use the fallback
+mechanism for this and a definition roughly boils down to this:
+
+\starttyping
+\definefontfallback
+  [mathdigits]
+  [dejavusansmono]
+  [digitsarabicindic]
+  [check=yes,
+   force=yes,
+   offset=digitsnormal]
+\stoptyping
+
+This is used in:
+
+\starttyping
+\definefontsynonym
+  [MathRoman]
+  [file:xits-math.otf]
+  [features=math\mathsizesuffix,
+   goodies=xits-math,
+   fallbacks=mathdigits]
+\stoptyping
+
+The problem with this kind of feature is not so much in the implementation,
+because by now in \CONTEXT\ we have plenty of ways to deal with such issues in a
+convenient way. The biggest challenge is to come up with an interface that
+somehow fits in the model of typescripts and with a couple of predefined
+typescripts we now have:
+
+\starttyping
+\usetypescriptfile[mathdigits]
+\usetypescript [mathdigits] [xits-dejavu] [arabicindic]
+\setupbodyfont[dejavu]
+\stoptyping
+
+\startbuffer[pefama]
+\definefontfeature [persian-fake-math] [arabic] [anum=yes]
+
+\definefont[persianfakemath][dejavusans*persian-fake-math]
+\stopbuffer
+
+\getbuffer[pefama]
+
+\def\PeFaMa#1{\mathord{\hbox{\persianfakemath#1}}}
+
+After that a formula like \type {$2 + 3 = 5$} comes out as $ \PeFaMa2 + \PeFaMa3
+= \PeFaMa5 $. In fact, if you want that in text mode, you can just use the
+\CONTEXT\ \MKIV\ font feature \type {anum}:
+
+\typebuffer[pefama]
+
+But of course you won't have proper math then. But as right|-|to|-|left math is
+still under construction, in due time we might end up with more advanced
+rendering. Currently you can exercise a little control. For instance by using the
+\type {align} parameter in combination with the \type {bidi} parameter. Of course
+support for special symbols like square roots depends on the font as well. We
+probably need to mirror a few more characters.
+
+\startbuffer
+  \m{   (  1 =   1)   }\quad
+  \m{   (123 = 123)   }\quad
+  \m{ a (  1 =   1) b }\quad
+  \m{ a (123 = 123) b }\quad
+  \m{ x = 123 y + (1 / \sqrt {x}) }
+\stopbuffer
+
+\typebuffer
+
+As in math we can assume sane usage of fences, we don't need extensive tests on
+pairing.

+\startsection[title=Structure]
+
+At some point publishers started asking for tagged \PDF\ and as a consequence a
+typeset math formula suddenly becomes more than a blob of ink. There are several
+arguments for tagging content. One is accessibility and another is reflow.
+Personally I think that both arguments are not that relevant. For instance, if
+you want to help a visually impaired reader, it's far better to start from a well
+structured original and ship that along with the typeset version. And, if you
+want reflow, you can better provide a (probably) simplified version in for
+instance \HTML\ format.
+
+We are surrounded by all kinds of visualizations, and text on paper or some
+medium is one. We don't make a painting accessible either. If accessibility is a
+demand, it should be done as best as can be, and the source is then the starting
+point. Of course publishers don't like that because when a source is available,
+it's one step closer to reuse by others. But that problem can simply be ignored
+as we consider publishers to be some kind of facilitating organization that
+deliver content from others. Alas publishers don't play that humble role so as
+long as they're around they can demand from their suppliers tagging of something
+visual.
+
+Of course when you use \TEX\ tagging is no real issue as you can make the input
+as verbose and structured as you like. But authors don't always want to be
+verbose, take this:
+
+\startbuffer
+$ f(x) = x^2 + 3x + 7 $
+\stopbuffer
+
+\typebuffer
+
+This enters \TEX\ as a sequence of characters: \enabletrackers [math.classes]
+\inlinebuffer \disabletrackers[math.classes]. These characters can have
+properties, for instance they can represent a relation or be an opening or
+closing symbol, but in most cases they are just classified as ordinary. These
+properties to some extent control spacing and interplay between math elements.
+They are not structure. If you have seen presentation \MATHML\ you have noticed
+that there are operators (\type {mo}), identifiers (\type {mi}) and numbers
+(\type {mn}), as well as some structural elements like fences (\type {mfenced}),
+superscripts (\type {msup}), subscripts (\type {msub}). Because it is a
+presentational encoding, there is no guarantee about the quality of the input as
+well as the rendering, but it somehow made it into a standard that is also used
+for tagging \PDF\ content.
+
+Going from mostly unstructured \TEX\ math input to more structured output is
+complicated by the fact that the intermediate somewhat structured math lists
+eventually become regular boxes, glyphs, kerns, glue etc. In \CONTEXT\ we carry
+some persistent information around so that we can still reverse engineer the
+output to structured input but this can be improved by more explicit tagging. We
+plan to add some more of that to future versions but here is an example:
+
+\starttyping
+$ \apply{f}{(x)} = x^2 + 3x + 7 $
+\stoptyping
+
+You can go over the top too:
+
+\starttyping
+$ \apply{f}{(x)} = \mi{x}^\mi{2} + \mi{3}\mi{x} + \mi{7} $
+\stoptyping
+
+The trick is to find an optimal mix of structure and readability. For instance,
+in \type {\sin} we already have the apply done by default, so often extra tagging
+is only needed in situations where there are several ways to interpret the text.
+Of course we're not enforcing this, but by providing some structure related
+features, at least we hope to make users aware of the issue. Directly inputting
+\MATHML\ is also an option but has never become popular.
+
+All this is mostly a macro package issue, and \CONTEXT\ has the basics on board.
+Because there is no need to adapt \LUATEX\ the most we will do is add a bit more
+consistency in building the lists (two way pointers) and carrying over properties
+(like attributes). We also have on the agenda a math table model that suits
+\MATHML, because some of those tables are somewhat hard to deal with.
+
+How the export and tagging evolves depends on demand. I must admit that I
+implemented it as an exercise mostly because these are features I don't need
+myself (and no one really asked for it anyway).
+
+\stopsection
+
+\startsection[title=Italic correction]
+
+Here we face a special situation. In regular \OPENTYPE\ italic correction is not
+part of the game, although one can cook up some positioning feature that does a
+similar job. In \OPENTYPE\ math there is italic correction, but also a more
+powerful sharpe|-|related kerning which is to be preferred. In traditional \TEX\
+the italic correction was present but since it is a font specific feature there
+is no way to make it work across fonts, and \TYPEONE\ based math has lots of
+them.
+
+At some point we have discussed throwing italic correction out of the engine, if
+only because it was unclear how and when to apply it. In the meantime there is
+some compromise reached. Because \CONTEXT\ is always in sync with the latest
+\LUATEX, we oscillated between solutions and this was complicated by the fact
+that we had to support a mix of \OPENTYPE\ math fonts and virtualized \TYPEONE\
+legacy fonts.
+
+The italic correction related code is still somewhat experimental, but we have
+several options. \footnote {In text mode we also have an advanced mechanism for
+italic correction but this operates independent from math.} In most cases we
+insert the italic correction ourselves and as the engine then sees a kern already
+it will not add another one. This has the advantage that we can be more
+consistent if only because not all fonts have these corrections and not all cases
+are considered by the engine.
+
+\startitemize[n]
+    \startitem
+        A math font can have italic correction per glyph. The engine gets
+        this passed but before it can apply them we already inject them into
+        the mathlist where needed.
+    \stopitem
+    \startitem
+        This is a variant of the first one, but is always applied, and not
+        controlled by the font. This makes it possible to add additional
+        corrections. This method is kind of obsolete as we no longer generate
+        missing corrections at font definition time. \footnote {Because the
+        font loader is also used for the generic code, we don't want to add
+        such features there.}
+    \stopitem
+    \startitem
+        This variant looks at the shape and if it is italic (or bolditalic) then
+        correction is applied. Here the correction is related to the emwidth
+        and controlled by a factor. We use this method by default.
+    \stopitem
+    \startitem
+        The fourth variant is a mixture of the first (font driven) and the third
+        (emwidth driven).
+    \stopitem
+\stopitemize
+
+Are we better off? I honestly don't know. It is a bit of a mess and will always
+be, simply because the reference font (cambria) and reference implementation
+(msword) is not clear about it and we follow them. In that respect I consider it
+a macro package issue mostly. In \CONTEXT\ at least we can offer some options.
+
+\startsection[title=Big]
+
+When migrating math to \MKIV\ I couldn't resist looking into some functionality
+that currently uses macro magic. An example is big delimiters.
+
+\startbuffer[bigs]
+$ ( \big( \Big( \bigg( \Bigg( x $
+\stopbuffer
+
+\typebuffer[bigs]
+
+\blank \getbuffer[bigs] \blank
+
+Personally I never use these, I just trust \type {\left} and \type {\right} to do
+the right job, but I'm no reference at all when it comes to math. The reason for
+looking into the bigs is that in plain \TEX\ there are some magic numbers
+involved. The macros, when translated to \CONTEXT\ boil down to this:
+
+\starttyping
+\left<delimiter>\vbox to 0.85\bodyfontsize{}\right.
+\left<delimiter>\vbox to 1.15\bodyfontsize{}\right.
+\left<delimiter>\vbox to 1.45\bodyfontsize{}\right.
+\left<delimiter>\vbox to 1.75\bodyfontsize{}\right.
+\stoptyping
+
+Knowing that we have a chain of sizes in the font, I was tempted to go for a
+solution where a specific size is chosen from the linked list of next sizes.
+There are several strategies possible when we delegate this to \LUA\ but we don't
+provide a high level interface yet. Personally I'd like to set the low level
+configuration options as:
+
+\starttyping
+\setconstant\bigmathdelimitermethod \plusone
+\setconstant\bigmathdelimitervariant\plusthree
+\stoptyping
+
+But as users might expect plain||like behaviour, \CONTEXT\ also provides the command
+
+\starttyping
+\plainbigdelimiters
+\stoptyping
+
+which sets the method to~2. Currently that is the default. When method~1 is
+chosen there are four variants and the reason for keeping them all is that they
+are part of experiments and explorations.
+
+\starttabulate[|||]
+\NC 1 \NC choose size $ \tf  n $ from the available sizes \NC \NR

+\startsection[title=Macros]
+
+I already discussed roots and the traditional \type {\root} command is a nice
+example of one that can be simplified in \LUATEX\ thanks to a new primitive. A
+macro package often has quite a lot of macros related to math that deal with
+tables and \LUATEX\ doesn't change that. But there is a category of commands that
+became obsolete: the ones that are used to construct characters that are not in
+the fonts. Keep in mind that the number of fonts as well as their size was
+limited at the time \TEX\ was written, so by providing building blocks additional
+characters could be made. Think of for instance the negated symbols: a new symbol
+could be made by overlaying a slash. The same is true for arrows: by prepending
+or appending minus signs, arrows of arbitrary length could be constructed.
+
+Here I will stick to another example: dots. In plain \TEX\ we have this definition:
+
+\starttyping
+\def\vdots
+  {\vbox
+     {\baselineskip4pt
+      \lineskiplimit0pt
+      \kern6pt
+      \hbox{.}%
+      \hbox{.}%
+      \hbox{.}}}
+\stoptyping
+
+This will typeset vertical dots, while the next does them diagonally:
+
+\starttyping
+\def\ddots
+  {\mathinner
+     {\mkern1mu
+      \raise7pt\vbox{\kern7pt\hbox{.}}%
+      \mkern2mu
+      \raise4pt\hbox{.}%
+      \mkern2mu
+      \raise1pt\hbox{.}%
+      \mkern1mu}}
+\stoptyping
+
+Of course these dimensions relate to the font size of plain \TEX\ so in \CONTEXT\
+\MKII\ we have something like this:
+
+\startbuffer
+\def\vdots
+  {\vbox
+     {\baselineskip4\points
+      \lineskiplimit\zeropoint

+These two symbols are rendered (in \MKII) as follows:
+
+\start \getbuffer
+
+\startlinecorrection[blank]
+\dontleavehmode \quad \ruledhbox{$\vdots$} \quad \ruledhbox{$\ddots$}
+\stoplinecorrection
+
+\stop
+
+I must admit that I only noticed the rather special height when I turned these
+macros into virtual characters for the initial virtual \UNICODE\ math that we
+needed in the first versions of \MKIV. This is a side effect of their use in
+matrices. However, in \MKIV\ we just use the characters in the font and get:
+
+\startlinecorrection[blank]
+\dontleavehmode \quad \ruledhbox{$\vdots$} \quad \ruledhbox{$\ddots$}
+\stoplinecorrection
+
+These characters look different because instead of three text periods a real
+symbol is used. The fact that we have more complete fonts and rely less on
+special font properties to achieve effects is a good thing, and in this respect
+it cannot be denied that \LUATEX\ triggered the development of more complete
+fonts. Of course from the user's perspective the outcome is often the same,
+although \unknown\ using a single character instead of three has the advantage of
+smaller files (neglectable), less runtime (really neglectable) and cleaner output
+files (undeniable) from where such characters can now be copied as one.

+
+This means as much as: when I hit \type {Ctrl-Z} on my keyboard and my editor
+honors that by injecting character \type {U+1A} into the input then \TEX\ will
+turn that into $\ne$, given that you're in math mode. I'm not sure how many
+keyboards and editors there are around that still do that but it illustrates that
+inputting in some kind of \WYSIWYG\ is not alien to \TEX. \footnote {There are
+more such hidden features, for instance, in some fonts special ligatures can be
+implemented that no one ever uses.}
+
+One of the subprojects of the ongoing \TEX\ user group font project is to extend
+the already extensive Dejavu font with all relevant math characters so that we
+can edit a document in a more \UNICODE\ savvy way. So, after more than three
+decades we might arrive where Don Knuth started: you see what you input and a
+similar shape will end up on paper.
+
+Does this mean that all such input is good? Definitely not, because in \UNICODE\
+we find all kinds of characters that somehow ended up there as a result of
+merging existing encodings. At work we're accustomed to getting input that is a
+mix of everything a word processor can produce and often we run into characters
+that users find normal but are not that handy from a \TEX\ perspective. It's the
+main reason why in math mode we intercept some of them, for instance in:
+
+\startbuffer
+$ y = x² + x³ + x²³ + x²ᵃ $ % not all characters are in monospace
+\stopbuffer
+
+\typebuffer
+
+These superscripts are an inconsistent bunch so they will never be real
+substitutes for the \type {^} syntax, simply because a mix like above looks bad.
+But fortunately it comes out well: \inlinebuffer. This is because \CONTEXT\ will
+transform such super- and subscripts into real ones and in the process also
+collapse multiple scripts into a group. This is typically one of the features
+that already showed up early in \MKIV.
+
+Here we have a feature that doesn't relate to fonts, the math machinery or the
+engine, but is just a macro package goodie. It's a way to respond to the
+variation in input, although probably hardly any \TEX\ math user will need it.
+It's one of those features that comes in handy when you use \TEX\ as invisible
+backend where the input is never seen by humans.
+
+\stopsection
+
+\startsection[title=Combining fonts]
+
+I already mentioned that we started out with virtual math fonts. Defining them is
+not that hard and boils down to defining what fonts make up the desired math
+font. Normally one starts out with a decent complete \OPENTYPE\ math font
+followed by mapping \TYPEONE\ fonts onto specific alphabets and symbols. On top
+of this there are additional virtual characters constructed (including
+extensibles). However, this method will become kind of obsolete (read: not used)
+when all relevant \OPENTYPE\ math fonts are available.
+
+Does this mean that we have only simple font setups? In practice yes: you can set
+up a math font in a few lines in a regular typescript. There are of course a few
+more lines needed when defining bold and|/|or right|-|to|-|left math but users
+don't need to bother about it. All is predefined. There are signals that users
+want to combine fonts so the already present fallback mechanism for text fonts
+has been made to work with math fonts as well. This permits for instance to
+complement the not|-|yet|-|finished \OPENTYPE\ Euler math fonts with Pagella. Of
+course you always need to keep consistency into account, but in principle you can
+overload for instance specific alphabets, something that can make sense when
+simple math is mixed with a font that has no math companion. In that case using
+the text italic in math mode might look better. For the at the time of this
+writing incomplete Euler font we can add characters like this:
+
+\starttyping
+\loadtypescriptfile[texgyre]
+\loadtypescriptfile[dejavu]
+
+\resetfontfallback  [euler]
+
+\definefontfallback [euler] [texgyrepagella-math] [0x02100-0x02BFF]
+\definefontfallback [euler] [texgyrepagella-math] [0x1D400-0x1D7FF]
+
+\starttypescript [serif] [euler] [name]
+  \setups[font:fallback:serif]
+  \definefontsynonym [Serif] [euler] [features=default]
+\stoptypescript
+
+\starttypescript [math] [euler] [name]
+  \definefontsynonym [MathRoman] [euler] [features=math\mathsizesuffix,fallbacks=euler]
+\stoptypescript
+
+\starttypescript [euler]
+  \definetypeface [\typescriptone] [rm] [serif] [euler]  [default]
+  \definetypeface [\typescriptone] [tt] [mono]  [dejavu] [default] [rscale=0.9]
+  \definetypeface [\typescriptone] [mm] [math]  [euler]  [default]
+\stoptypescript
+\stoptyping
+
+If needed one can use names instead of code ranges (like \type {uppercasescript})
+as well as map one range onto another. This last option is handy for merging a
+regular text font into an alphabet (in which case the \UNICODE's don't match).
+
+We expect math fonts to be rather complete because after all, a font designer has
+a large repertoire of free alphabets to choose from. So, in practice combining
+math fonts will happen seldom. In text mode this is more common, especially when
+multiple scripts are mixed. There is a whole bunch of modules that can generate
+all kind of tables and overviews for testing.
+
+\stopsection
+
+\startsection[title=Experiments]
+
+I won't describe all experiments here. An example of an experiment is a better
+way of dealing with punctuation, especially the cultural determined
+period|/|comma treatment. I still have the code somewhere but the heuristics are
+too messy to keep around.
+
+There are also some planned experiments, like breaking and aligning display math,
+but they have a low priority. It's not that hard to do, but I need a good reason.
+The same is true for equation number placement where primitives are used that can
+sometimes interfere or not be used in all cases. Currently that placement in
+combination with alignments is implemented with quite a lot of fuzzy macro code.
+
+One of the areas where experimenting will continue is with fonts. Early in the
+development of \MKIV\ font goodies showed up. A font (or collection of fonts) can
+have a file (or more files) that control functionality and can have fixes. There
+are some in place for math fonts. It is a convenient way to use the latest
+greatest fonts as we have ways to circumvent issues, for instance with math
+parameters. The virtual math fonts are also defined as goodies.
+
+Some mechanisms will probably be made accessible from the \TEX\ end so that users
+can exercise more control. And because we're not done yet, additional features
+will show up for sure. There are some math related subsystems like physics and
+chemistry and these already demanded some extensions and might need more.
+Introducing math symbol (and property) dictionaries as in \OPENMATH\ is probably
+a next step.
+
+I already mentioned that typesetting and rendering related technology is driven
+by the web. This also reflects on \UNICODE\ and \OPENTYPE. For instance, we find
+not only emoticons like \type {U+1F632} (ASTONISHED FACE) in the standard but
+also \quote {MOUNT FUJI}, \type {TOKYO TOWER}, \type {STATUE OF LIBERTY}, \type
+{SILHOUETTE OF JAPAN}. On the other hand, in one of our older projects we still
+have to provide some tweak for the unary minus (as when discussing scientific
+calculators used in math lessons) a distinction has to be made with a regular
+minus sign. And there are no symbols to refer to use of media (simulation,
+applet, etc.) and there is as far as I know no emoticon for a student asking a
+question. Somehow it's hard to defend that the Planck constant is as different
+from a math italic~h as a \quote {GRINNING FACE} is from a \quote {GRINNING FACE
+WITH SMILING EYES}, but the last both got a code point. I wonder with an \type
+{UNAMUSED FACE}.
+
+Of course we can argue that this is all too visual to end up in \UNICODE, but the
+main point that I want to make is that as a \TEX\ community (which is also
+related to education) we are of not that much importance and influence. Maybe it
+is because we always had a programmable system at hand, and folks who could make
+fonts, and were already extending and exploring before the web became a factor.
+Anyhow, in \CONTEXT\ we solve these issues by making mechanisms extensible. For
+instance we can extend fonts with virtual glyphs and add features to existing
+fonts on the fly. Simple examples are adding some glyphs and properties to math
+fonts or adding color properties to whatever font. More complex examples are
+implementing paragraph optimizers using feature sets of fonts (most noticeably
+the upcoming Husayni font for advanced arabic typesetting). And, math typesetting
+is a speciality anyway.
+
+Upcoming extensions to \UNICODE\ and \OPENTYPE\ will demonstrate that the \TEX\
+community could have been a bit more demanding and innovative, given that it had
+known what to demand. Interesting is that some innovation already happened by
+providing special fonts and macros and engines, but I guess much gets unnoticed.
+On the other hand, I must admit that experimenting and providing solutions
+independent of evolving technology also has benefits: it made (and makes) some
+user group meetings interesting to go to and creates interesting niches of users.
+Without this experimental playground I for sure would not be around.
+
+\stopsection
+
+\startsection[title=Tracing]
+
+Tracing is available for nearly all mechanisms and math is no exception. Most
+tracing happens at the \LUA\ end and can be enabled with the tracker mechanism.
+Users will seldom use this, but for development the situation is definitely more
+comfortable in \MKIV. Of course it helps that the penalty of tracing and logging
+has become less in recent times because memory as well as runtime is hardly
+influenced.
+
+We provide several styles (modules) for generating lists and tables of characters
+and extensibles, visualizing features and comparing fonts. Here we benefit from
+\LUA\ because we can use the database embedded in \CONTEXT\ and looping and
+testing is more convenient in this language. Of course the rendering is done by
+\TEX, so this is a typical example of hybrid usage.
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+It is somewhat ironic that while \CONTEXT\ is sometimes tagged as \quote {not to
+be used when you need to do math typesetting} it is this macro package that
+drives the development of \LUATEX\ with its updated math engine, which in turn
+influences the updated math engine in \XETEX, that is used by other macro
+packages. In a similar fashion the possibility to process \OPENTYPE\ math fonts
+in \LUATEX\ triggered the development of such fonts as follow up on the Latin
+Modern and \TEX\ Gyre projects. So, the fact that in \CONTEXT\ we have a bit more
+freedom in experimenting with math (and engines) has some generic benefits as
+well.
+
+I think that overall we're better off. The implementation at the \TEX\ end is
+much cleaner because we no longer have to deal with different math encodings and
+multiple families. Because in \CONTEXT\ we're less bound to traditional
+approaches and don't need to be code compatible with other engines we can follow
+different routes than usual. After all, that was also one of the main motivations
+behind starting the \LUATEX\ project: clean (better understandable code), less
+mean (no more hacks at the \TEX\ end), even if that means to be less lean (quite
+a lot of \LUA\ code). Between the lines above you can read that I think that
+we've missed some opportunities but that's a side effect of the community not
+being that innovative which in turn is probably driven by more or less standard
+expectations of publishers, as they are more served by good old stability instead
+of progress. Therefore, we're probably stuck for a while, if not forever, with
+what we have now. And a decent \CONTEXT\ math implementation is not going to
+change that. What matters is that we can (still) keep up with developments
+outside our sphere of influence.
+
+I don't claim that the current implementation of math in \MKIV\ is flawless, but
+eventually we will get there.

+\startchapter[title=\LUATEX\ going stable]
+
+\startsection[title=Introduction]
+
+We're closing in on version 1.0 of \LUATEX\ and at the time of this writing (mid
+April 2016) we're at version 0.95. The last decade we've reported on a regular
+basis about progress in user group journals, \CONTEXT\ related documents and the
+\LUATEX\ manual and it makes no sense to repeat ourselves.
+
+So where do we stand now? I will not go into details about what is available in
+\LUATEX, for that you consult the manual but will stick to the larger picture
+instead.
+
+\stopsection
+
+\startsection[title=What is it]
+
+First of all, as the name suggests, \LUATEX\ has the \LUA\ scripting engine on
+board. Currently we're still at version 5.2 and the reason for not going 5.3 is
+mainly because it has a different implementation of numbers and we cannot foresee
+side effects. We will test this when we move on to \LUATEX\ version 2.0.
+
+The second part of the name indicates that we have some kind of \TEX\ and we
+think we managed to remain largely compatible with the traditional engine. We
+took most of \ETEX, much of \PDFTEX\ and some from \ALEPH\ (\OMEGA). On top of
+that we added a few new primitives and extended others.
+
+If you look at the building blocks of \TEX, you can roughly recognize these:
+
+\startitemize
+\startitem
+    an input parser (tokenizer) that includes macro expansion; its working is
+    well described, of course in the \TEX\ book, but more than three decades of
+    availability has made \TEX's behaviour rather well documented
+\stopitem
+\startitem
+    a list builder that links basic elements like characters (tagged with font
+    information), rules, boxes, glue and kerns together in a double linked
+    list of so called nodes (and noads in intermediate math lists)
+\stopitem
+\startitem
+    a language subsystem that is responsible for hyphenating words using so called
+    patterns and exceptions
+\stopitem
+\startitem
+    a font subsystem that provides information about glyphs properties, and that
+    also makes it possible to construct math symbols from snippets; it also makes
+    sure that the backend knows what to embed
+\stopitem
+\startitem
+    a paragraph builder that breaks a long list into lines and a page builder
+    that splits of chunks that can be wrapped into pages; this is all done within
+    given constraints using a model of rewards and penalties
+\stopitem
+\startitem
+    a first class math renderer that set the standard and has inspired modern
+    math font technology
+\stopitem
+\startitem
+    mechanisms for dealing with floating data, marking page related info, wrapping
+    stuff in boxes, adding glue, penalties and special information
+\stopitem
+\startitem
+    a backend that is responsible for wrapping everything typeset in a format that
+    can be printed and viewed
+\stopitem
+\stopitemize
+
+So far we're still talking of a rather generic variant of \TEX\ with \LUA\ as
+extension language. Next we zoom in on some details.
+
+\stopsection
+
+\startsection[title=Where it differs]
+
+Given experiences with discussing extensions to the engine and given the fact
+that there is never really an agreement about what makes sense or not, the
+decission was made to not extend the engine any more than really needed but to
+provide hooks to do that in \LUA. And, time has proven that this is a feasible
+approach. On the one hand we are as good as possible faithful to the original,
+and at the same time we can deal with todays and near future demands.
+
+Tokenization still happens as before but we can also write input parsers
+ourselves. You can intercept the raw input when it gets read from file, but you
+can also create scanners that you can sort of plug into the parser. Both are a
+compromise between convenience and speed but powerful enough. At the input end we
+now can group catcode changes (catcodes are properties of characters that control
+how they are interpreted) into tables so that switching between regimes is fast.
+
+You can in great detail influence how data gets read from files because the \IO\
+subsystem is opened up. In fact, you have the full power of \LUA\ available when
+doing so. At the same time you can print back from \LUA\ into the input stream.
+
+The input that makes in into \TEX, either or not intercepted and manipulated
+beforehand, is to be in \UTF8. What comes out to the terminal and log is also
+\UTF8, and internally all codepaths work with wide characters. Some memory
+constraints have been lifted, and character related commands accept large
+numbers. This comes at a price, which means that in practice the \LUATEX\ engine
+can be several times slower than the 8|-|bit \PDFTEX, but of course in practice
+performance is mostly determined by the efficiency of macro package, so it might
+actually be faster in situations that would stress its ancestors.
+
+Node lists travel through \TEX\ and can be intercepted at many points. That way
+you can add additional manipulations. You can for instance rely on \TEX\ for
+hyphenation, ligature building and kerning but you can also plug in alternatives.
+For this purpose these stages are clearly separated and less integrated (deep
+down) than in traditional \TEX. There are helpers for accessing lists of nodes,
+individual nodes and you can box those lists too (this is called packing). You
+can adapt, create and destroy node lists at will, as long as you make sure you
+feed back into \TEX\ something that makes sense.
+
+In order to control (or communicate with) nodes from the \TEX\ end, an attribute
+mechanism was added that makes it possible to bind properties to nodes when they
+get added to lists. At the \TEX\ end you can set an attribute that then gets
+assigned to the currently injected nodes, while at the \LUA\ end you can query
+the node for these attributes and their values.
+
+The language subsystem is re|-|implemented and behaves mostly the same as in the
+original \TEX\ program. It has a few extensions and permits runtime loading of
+patterns. In addition to language support we also have basic script support, that
+is: directional information is now part of the stream and contrary to \ALEPH\
+that wraps this into extension whatsits, in \LUATEX\ we have directional nodes as
+core nodes.
+
+The font subsystem is opened up in such a way that you can pass your own fonts to
+the core. You can even construct virtual fonts. This open approach makes it
+possible to support \OPENTYPE\ fonts and whatever format will show up in the
+future. Of course the backend needs to embed the right data in the result file
+but by then the hard work is already done. This approach fits into the always
+present wish of users (and package writers) to be able to implement whatever
+crazy thought one comes up with.
+
+The paragraph builder is a somewhat cleaned up variant of the \PDFTEX\ one,
+combined with directional and boundary support from \ALEPH. The protrusion and
+expansion mechanism have been redone in such a way that the front- and backend
+code is better separated and is somewhat more efficient now. As one can intercept
+the paragraph builder, additional functionality can be injected before, after or
+at some stages in the process.
+
+Of course we have kept the math engine but, because we now need to support
+\OPENTYPE\ math, alternative code paths have been added to deal with the kind of
+information that such fonts provide. We also took the opportunity to open up the
+math machinery a bit so that one can control rendering of some more complex
+elements and set the spacing between elements. Because \TEX\ users are quite
+traditional we had to stop somewhere, simply because legacy code has to be dealt
+with.
+
+Most mentioned auxiliary mechanisms can be accessed via the node lists, for
+instance you can locate inserts and marks in them. The backend related whatsit
+nodes can be recognized as well. At any time one can query and set \TEX\
+registers and intercept boxed material. Of course some knowledge of the inner
+working of \TEX\ helps here.
+
+The backend code is as much as possible separated from the frontend code (but
+there is still some work to do there). As in \PDFTEX\ you can of course inject
+arbitrary \PDF\ code and make feature rich documents. This flexibility keeps
+\TEX\ current.
+
+\stopsection
+
+\startsection[title=Extras]
+
+Is that all? No, apart from some minor extensions that might help to make
+programming somewhat easier \TEX, there are a few more fundamental additions.
+
+Images and reusable content (boxes) are now part of the core instead of them
+being wrapped into backend specific whatsits, although of course the backend has
+to provide support for it. This is more natural in the frontend (and user
+interface) and also more consistent in the engine itself. All backend
+functionality is now collected in three primitives that take arguments. This
+permits a cleaner separation between front- and backend.
+
+Then there is the \METAPOST\ library, a feature already present for many years
+now. It provides \TEX\ with some graphic capabilities that, given the origin,
+fits nicely into the whole. The \LUATEX\ and \MPLIB\ project started about the
+same time and right from the start it was our plan to combine both.
+
+One of the extras is of course \LUA. It not only permits us to interface to the
+internals of \TEX, but it also provides the user with a way to manipulate data.
+Even if you never use \LUA\ to access internals, it might still be found useful
+for occasionally doing things that are hard to accomplish using the macro
+langage.
+
+In addition to stock \LUA\ we include the \LPEG\ library, an image reading
+library (related to the backend) including read access to \PDF\ files via the
+used poppler library, parsing of \PDF\ content streams, zip compression, access
+to the file system, the ability to run commands and socket support. Some of this
+might become external libraries at some point, as we want to keep the expected
+core functionality lean and mean. A nice extra is that we provide \LUAJITTEX, a
+compatible variant that has a faster \LUA\ virtual machine on board.
+
+\stopsection
+
+\startsection[title=Follow up]
+
+The interfaces that we have now have to a large extent evolved to what we had in
+mind. We started with simple experiments: just \LUA\ plus a bit of access to
+registers. Then the Oriental \TEX\ project (with Idris Samawi Hamid) made it
+possible to speed up development and conversion to \CCODE\ and opening up took
+off. After that we gradually moved forward.
+
+That doesn't mean that we're done yet. The \LUATEX\ 1.0 engine will not change
+much. We might add a few things, and for sure we will keep working on the code
+base. The move from \PASCAL\ to \CCODE\ \WEB\ (an impressive job by itself), as
+well as merging functionality of engines (kind of a challenge when you want to
+remain compatible), opening up via \LUA\ (which possibilities even surprised us),
+and experimenting (\CONTEXT\ users paid the price for that) took quite some time,
+also because we played with proofs of concept. It helped that we used the engine
+exclusively for real typesetting related work ourselves.
+
+We will continue to clean up and document the source and stepwise improve the
+manual. If you followed the development of \CONTEXT, you will have noticed that
+\MKIV\ is heavily relying on the \LUA\ interface so stability is important
+(although we can relatively easy adapt to future developments as we did in the
+past). However, the fact that other packages support \LUATEX\ means that we also
+need to keep the 1.0 engine stable. Our challenge is to provide stability on the
+one hand, but not limit ourselves to much on the other. We'll keep you posted on
+what comes next.

+\startchapter[title=Opentype math]
+
+\startsection[title=Introduction]
+
+When \TEX\ typesets mathematics it makes some assumptions about the properties of
+fonts and dimensions of glyphs. Due to practical limitations in the traditional
+eight|-|bit fonts, such as the number of available characters in a font and a
+limited number of heights and depths, some juggling takes place. For instance,
+\TEX\ sometimes uses dimensions as a signal to treat some characters as special.
+This is not a problem as long as one knows how to make a font and in practice
+that was done by looking at the properties of Computer Modern to implement
+similar shapes. After all, there are not that many math fonts around and
+basically there is only one engine that can deal with them properly.
+
+However, when Microsoft set the standard for \OPENTYPE\ math fonts it also
+steered the direction of their use in rendering mathematics. This means that the
+\LUATEX\ engine, which handles \OPENTYPE\ fonts, has to implement some
+alternative code paths. At the start, this involved a bit of gambling because
+there was no real specification; since then we now have a better picture. One of
+the more complex changes that took place is in the way italic correction is
+applied. A dirty way out of this dilemma would be to turn the math fonts into
+virtual ones that match traditional \TEX\ properties, but this would not be a
+nice solution.
+
+It must be noted that in the process of implementing support for the new fonts,
+Taco (Hoekwater) turned some noad types (see below) into a generic noad with a subtype. This
+simplified the transition. At the same time, a lot of detailed control was added
+in the way successive characters are spaced.
+
+In \LUATEX\ before 0.85, the italic correction was always added when a character got
+boxed (a frequently used preparation in the math builder). Now this is only done
+for the traditional fonts because, concerning italic correction, the \OPENTYPE\
+standard states: \footnote {Recently version 1.8 has been published on the Microsoft
+website.}
+
+\startitemize[n]
+    \startitem
+        When a run of slanted characters is followed by a straight character
+        (such as an operator or a delimiter), the italics correction of the last
+        glyph is added to its advance width.
+    \stopitem
+    \startitem
+        When positioning limits on an N-ary operator (e.g., integral sign), the
+        horizontal position of the upper limit is moved to the right by half of the
+        italics correction, while the position of the lower limit is moved to the
+        left by the same distance.
+    \stopitem
+    \startitem
+        When positioning superscripts and subscripts, their default horizontal
+        positions are also different by the amount of the italics correction of
+        the preceding glyph.
+    \stopitem
+\stopitemize
+
+And, with respect to kerning:
+
+\startitemize[continue]
+    \startitem
+        Set the default horizontal position for the superscript as shifted
+        relative to the position of the subscript by the italics correction of
+        the base glyph.
+    \stopitem
+\stopitemize
+
+I must admit that when the first implementation showed up, my natural reaction to
+unexpected behaviour was just to compensate for it. One such solution was simply not
+to pass the italic correction to the engine and deal with it in \LUA. In
+practice, that didn't work well for all cases; one reason was that the engine
+saw the combination of old fonts as a new one and followed a mixed code path.
+\footnote {\CONTEXT\ employed \UNICODE\ math right from the start of \LUATEX.}
+Another approach I tried was a mix of manipulated italic values and \LUA, but
+finally, as specifications settled I decided to leave it to the engine completely,
+if only because successive versions of \LUATEX\ behaved much better.
+
+So, as we were closing in on the first stable release of \LUATEX\ (1.0.0
+was released on September~27, 2016; this note was mostly written in the
+early part of 2016), I decided to fix the
+pending issues and sat down to look at the math|-|related code. I must admit that I
+had never looked in depth into that part of the machinery. In the next sections I
+will discuss some of the outcomes of this exercise.
+
+I will also discuss some extensions that have been on the agenda for years. They
+are rather generic and handy, but I must also admit that the \MKIV\ code related
+to math has so many options to control rendering that I'm not sure if they will
+ever be used in \CONTEXT. Nevertheless, these generic extensions fit well into
+the set of basic features of \LUATEX.
+

+
+\startsection[title=Italic correction]
+
+As stated above, the normal code path included italic correction in all the math
+boxes made. This meant that, in some places, the correction had to be
+removed and/or moved to another place in the chain. This is a natural side effect
+of the fact that \TEX\ runs over the intermediate list of math nodes (noads) and
+turns them into regular nodes, mostly glyphs, kerns, glue and boxes.
+
+The complication is not so much the italic corrections themselves, because we
+could just continue to do the same, but the fact that these corrections are to be
+interpreted differently in case of integrals. There, the problem is that we have
+to (kind of) look backward at what is done in order to determine what italic
+corrections are to be applied.
+
+The original solution was to keep track of the applied correction via variables
+but that still made some analysis necessary. In the new implementation, more
+information is stored in the processed noads. This is a logical choice given that
+we have already added other information. It also makes it possible to fix cases
+that will (for sure) show up in the future.

+The \type {axis} keyword will apply a shift up over the size of the current

+
+In \in {figure} [fig:demoint] you can see some subtle differences. The wrapped
+version doesn't shift the superscript and subscript. The reason is that the
+operator is hidden in its own wrapper and the scripts attach at an outer level.
+So, unless we start analyzing the innermost noad and apply that to the outer, we
+cannot know the shift. Such analyzing is asking for problems: where do we stop
+and what slight variations do we take into account? It's better to be
+predictable.

+Another observation is that Latin Modern does not provide (at least not yet)

+
+The following four cases are equivalent:
+
+\starttyping

+\Uleft   .
+\Umiddle height 3ex depth 3ex axis \Udelimiter "0 "0 "222B
+\Uright  .
+\stoptyping
+
+However, because this all looks a bit clumsy, we now provide a new
+primitive:
+
+\starttyping
+\Uvextensible
+    height <dimension>
+    depth <dimension>
+    axis
+    exact
+    <delimiter>
+\stoptyping
+
+The symbol to be constructed will have size \type {height} plus \type {depth}.
+When an \type {axis} is specified, the symbol will be shifted up, which is
+normally the case for such symbols. The keyword \type {exact} will correct the
+dimensions when no exact match is made, and this can be the case as long as we
+use the stepwise larger glyphs and before we end up using the composed shapes.
+When no dimensions are specified, the normal construction takes place and the
+only keyword that can be used then is \type {noaxis} which keeps the axis out of
+the calculations. After about a week of experimenting and exploring options, this
+combination made most sense, read: no fuzzy heuristics but predictable behaviour.
+After all, one might need different solutions for different fonts or
+circumstances and the applied logic (and expectations) can (and will, for sure)
+differ per macro package.

+Horizontal extenders also have some new options. Although one can achieve similar
+results with macros, the following might look a bit more natural. Also, some
+properties are lost once the delimiter is constructed, so macros can become
+complex when trying to determine the original dimensions involved.
+
+We start with the new \type {\Uhextensible} primitive that accepts a dimension.
+It's just a variant of the over and under delimiters with no content part.

+\startsection[title=Accents]
+
+Many years ago, I observed that overlaying characters (which happens when
+we negate an operator which has no composed negation glyph) didn't always give nice results
+and, therefore, a tracker item was created. When going over the todo list, I ran
+across a suggested patch by Khaled Hosny that added an overlay accent type. As
+the suggested solution fits in with the other extensions, a variant has been
+implemented.
+
+The results definitely depend on the quality and completeness of the font, so here we
+will show \type {xits}. The placement of an \type {overlay} also depends on the top
+accent shift as specified in the font for the used glyph. Instead of a fixed
+criterion for trying to find the best match, an additional \type {fraction}
+(numerator) parameter can be specified. A value of $800$ means that the target
+width is $800/1000$.
+
+The \type {\Umathaccent} command now has the following syntax:
+
+\starttyping
+\Umathaccent
+    [top|bottom|overlay]
+    [fixed]
+    [fraction <number>]
+    <delimiter>
+    {content}
+\stoptyping
+
+When we have an overlay, the fraction concerns the height; otherwise it concerns
+the width of the nucleus. In both cases, it is only applied when searching for
+stepwise larger glyphs, as extensibles are not influenced. An example of a
+specification is:
+
+\starttyping
+\Umathaccent
+    overlay "0 "0 "0338
+    fraction 950
+    {\Umathchar"1"0"2211}
+\stoptyping
+
+\in {Figure} [fig:accent-1] shows what we get when we use different fractions
+(from 800 up to 1500 with a step of 100). We see that \type {\overlay} is not
+always useful.

+\startsection[title=Fractions]
+
+A normal fraction has a reasonable thick rule but as soon as you make it bigger you
+will notice a peculiar effect:
+
+\startlinecorrection
+\startcombination[5*1]
+   {$\displaystyle x + {{a} \abovewithdelims() 1pt {b}}$} {1pt}
+   {$\displaystyle x + {{a} \abovewithdelims() 2pt {b}}$} {2pt}
+   {$\displaystyle x + {{a} \abovewithdelims() 3pt {b}}$} {3pt}
+   {$\displaystyle x + {{a} \abovewithdelims() 4pt {b}}$} {4pt}
+   {$\displaystyle x + {{a} \abovewithdelims() 5pt {b}}$} {5pt}
+\stopcombination
+\stoplinecorrection
+
+Such a fraction is specified as:
+
+\starttyping
+x + { {a} \abovewithdelims () 5pt {b} }
+\stoptyping
+
+A new keyword \type {exact} avoids the excessive spacing:
+
+\starttyping
+x + { {a} \abovewithdelims () exact 5pt {b} }
+\stoptyping
+
+Now we get:
+
+\startlinecorrection
+\startcombination[5*1]
+   {$\displaystyle x + {{a} \abovewithdelims() exact 1pt {b}}$} {1pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 2pt {b}}$} {2pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 3pt {b}}$} {3pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 4pt {b}}$} {4pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 5pt {b}}$} {5pt}
+\stopcombination
+\stoplinecorrection
+
+One way to get consistent spacing in such fractions is to use struts:
+
+\starttyping
+x + { {\strut a} \abovewithdelims () exact 5pt {\strut b} }
+\stoptyping
+
+Now we get:
+
+\startlinecorrection
+\startcombination[5*1]
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 1pt {\strut b}}$} {1pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 2pt {\strut b}}$} {2pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 3pt {\strut b}}$} {3pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 4pt {\strut b}}$} {4pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 5pt {\strut b}}$} {5pt}
+\stopcombination
+\stoplinecorrection
+
+Yet another way to increase the distance between the rule and text a bit is:
+
+\starttyping
+\Umathfractionnumvgap  \displaystyle4pt
+\Umathfractiondenomvgap\displaystyle4pt
+\stoptyping
+
+This looks quite consistent:
+
+\startlinecorrection
+\Umathfractionnumvgap  \displaystyle4pt
+\Umathfractiondenomvgap\displaystyle4pt
+\startcombination[5*1]
+   {$\displaystyle x + {{a} \abovewithdelims() exact 1pt {b}}$} {1pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 2pt {b}}$} {2pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 3pt {b}}$} {3pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 4pt {b}}$} {4pt}
+   {$\displaystyle x + {{a} \abovewithdelims() exact 5pt {b}}$} {5pt}
+\stopcombination
+\stoplinecorrection
+
+Here we use code like:
+
+\starttyping
+$\displaystyle x + {{a} \abovewithdelims() exact 2pt {b}}$
+\stoptyping
+
+Using struts, it is best to zero the gap:
+
+\startlinecorrection
+\Umathfractionnumvgap  \displaystyle0pt
+\Umathfractiondenomvgap\displaystyle0pt
+\startcombination[5*1]
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 1pt {\strut b}}$} {1pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 2pt {\strut b}}$} {2pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 3pt {\strut b}}$} {3pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 4pt {\strut b}}$} {4pt}
+   {$\displaystyle x + {{\strut a} \abovewithdelims() exact 5pt {\strut b}}$} {5pt}
+\stopcombination
+\stoplinecorrection
+
+Here we use code like:
+
+\starttyping
+$\displaystyle x + {{\strut a} \abovewithdelims() exact 2pt {\strut b}}$
+\stoptyping
+

+\startsection[title=Skewed fractions]
+
+The math parameter table contains values specifying horizontal and
+vertical gaps for skewed fractions. Some guessing is needed in order to implement
+something that uses them, so we now provide a primitive similar to the other
+fraction related ones but with a few options that one can use to influence the
+rendering. Of course, a user can mess around directly with the parameters \type
+{\Umathskewedfractionhgap} and \type {\Umathskewedfractionvgap}.
+
+The syntax used here is:
+
+\starttyping
+{ {1} \Uskewed / <options> {2} }
+{ {1} \Uskewedwithdelims / () <options> {2} }
+\stoptyping
+
+The options can be \type {noaxis} and \type {exact}, a combination of them or
+just nothing. By default we add half the axis to the shifts and also by default
+we zero the width of the middle character. For Latin Modern, the result looks as
+follows:
+
+\def\ShowA#1#2#3{$x + { {#1} \Uskewed           /    #3 {#2} } + x$}

+\startsection[title=Side effects]
+
+Not all bugs reported as such are really bugs. Here is one that came from a
+misunderstanding: In Eijkhout's \quotation {\TEX\ by Topic}, the rules for
+handling styles in scripts are described as follows:
+
+\startitemize
+\startitem
+    In any style superscripts and subscripts are taken from the next smaller
+    style. Exception: in display style they are taken in script style.
+\stopitem
+\startitem
+    Subscripts are always in the cramped variant of the style; superscripts are
+    only cramped if the original style was cramped.
+\stopitem
+\startitem
+    In an \type {..\over..} formula in any style the numerator and denominator
+    are taken from the next smaller style.
+\stopitem
+\startitem
+    The denominator is always in cramped style; the numerator is only in cramped
+    style if the original style was cramped.
+\stopitem
+\startitem
+    Formulas under a \type {\sqrt} or \type {\overline} are in cramped style.
+\stopitem
+\stopitemize
+
+In \LUATEX, one can set the styles in more detail, which means that you sometimes
+have to set both normal and cramped styles to get the effect you want. If we
+force styles in the script using \type {\scriptstyle} and \type
+{\crampedscriptstyle} we get the following (all render the same):
+
+\startbuffer[demo]
+\starttabulate
+\NC default       \NC $b_{x=xx}^{x=xx}$ \NC \NR
+\NC script        \NC $b_{\scriptstyle x=xx}^{\scriptstyle x=xx}$ \NC \NR
+\NC crampedscript \NC $b_{\crampedscriptstyle x=xx}^{\crampedscriptstyle x=xx}$ \NC \NR
+\stoptabulate
+\stopbuffer
+
+\getbuffer[demo]
+
+This is coded like:
+
+\starttyping
+$b_{x=xx}^{x=xx}$
+$b_{\scriptstyle x=xx}^{\scriptstyle x=xx}$
+$b_{\crampedscriptstyle x=xx}^{\crampedscriptstyle x=xx}$
+\stoptyping
+
+Now we set the following parameters:
+
+\startbuffer[setup]
+\Umathordrelspacing\scriptstyle=30mu
+\Umathordordspacing\scriptstyle=30mu
+\stopbuffer
+
+\typebuffer[setup]
+
+This gives:
+
+\start\getbuffer[setup,demo]\stop
+
+Since the result is not what is expected (visually), we should say:
+
+\startbuffer[setup]
+\Umathordrelspacing\scriptstyle=30mu
+\Umathordordspacing\scriptstyle=30mu
+\Umathordrelspacing\crampedscriptstyle=30mu
+\Umathordordspacing\crampedscriptstyle=30mu
+\stopbuffer
+
+\typebuffer[setup]
+
+Now we get:

+The changes that we have made are hopefully not too intrusive. Instead of
+extending existing commands, new ones were introduced so that compatibility
+should not be a significant problem. To some extent, these extensions violate the
+principle that extensions should be done in \LUA, but \TEX\ being a math renderer
+and \OPENTYPE\ replacing old font technology, we felt that we should make an
+exception here. Hopefully, not too many bugs were introduced.

+\startsection[title=Introduction]
+
+Although \TEX\ is pretty good at typesetting simple texts like novels, in
+practice it's often used for getting more complex stuff on paper (or screen).
+Math is of course the first thing that comes to mind. If for instance you look at
+the books typeset by Don Knuth you will see a rendering that is rather consistent
+in spacing. This is no surprise as the author pays a lot of attention to detail
+and uses inline versus display math properly. No publisher will complain about
+the result.
+
+In the documents that I have to write styles for, the content is rather mixed,
+and in particular inline math can have display math properties. In a one-column
+layout this is not a real problem especially because lots of short sentences and
+white space is used: we're talking of secondary|-|school educational math where
+arguments for formatting something this or that way is not always rational and
+consistent but more based on \quotation {this is what the student expects},
+\quotation {the competitor also does it that way} or just \quotation {we like
+this more}. For instance in a recent project, the books with answers to questions
+had to be typeset in a multicolumn layout and because math was involved, we end
+up with lines with more height and depth than normal. That can not only result in
+more pages but also can make the result look a bit messy.
+
+\blank \dontleavehmode \start \showboxes This paragraph demonstrates how lines
+are handled: when a paragraph is broken into lines each line becomes a horizontal
+box with a height and depth determined by the size of the characters that make up
+the line. There is a minimal distance between baselines (\type {baselineskip})
+and when lines touch there can optionally be a \type {\lineskip}. In the end we
+get a vertical list of boxes and glue (either of not flexible) mixed with
+penalties that determine optimal paragraph breaks. This paragraph shows that
+there is normally enough space available to do the job. \par \stop \blank
+
+We already have some ways to control this. For instance the dimensions of math
+can be limited a bit and lines can be made to snap on a grid (which is what
+publishers often want anyway). However, another alternative is to look at the
+line and decide if successive lines can be moved closer, of course within the
+constraints of the height and and depth of the lines. There is no real way to see
+if some ugly clash can happen simply because when we run into boxed material
+there can be anything inside and the dimensions can be set on purpose. This means
+that we have to honour all dimensions and only can mess around with dimensions
+when we're reasonably confident. In \CONTEXT\ this messing is called profiling
+and that is what we will discuss next.

+Regelmatig kom je procenten tegen. ‘Pro centum’ is Latijn en betekent per
+honderd, dus één van elke honderd, dus \math {\frac {1} {100}} deel. Met
+procenten rekenen is daarom rekenen met honderdsten: \math {45 \procent = \frac
+{45} {100} = 0,45}. Dus \math {45 \procent} van een geheel is het \math {\frac
+{45} {100}} deel ervan en dat kun je berekenen door te vermenigvuldigen met \math
+{0,45}.

+Je gaat uit van de bekende eigenschappen van machten. Bijvoorbeeld: \math {g^r *
+g^s = g^{(r+s)}}. Neem je hierin \math {r = ^{g}\log(a)} en \math {s = ^{g}\log
+b}, dan vind je: \math {g^{^{g}\log(a) + ^{g}\log(b)} = g^{^{g}\log a} \times
+g^{^{g}\log b} = a \times b}. Hierbij gebruik je de definitieformules.
+\stopbuffer

+Omdat volgens de eigenschappen van machten en exponenten geldt \math {\frac {1}
+{x^4} = x^{-4} } is ook hier sprake van een machtsfunctie, namelijk \math {f(x) =

+In this section we will use some (Dutch) examples from documents that we've
+processed. We show unprofiled versions, with two different paragraph widths, in
+\in {figure} [fig:profiling:unprofiled-examples-widths]. All three examples shown
+demonstrate that as soon as we use something more complex than a number or
+variable in a subscript we exceed the normal line height, and thus the line
+spacing becomes somewhat irregular.

+In the first and last example there are some lines where the depth of one line
+combined with the height of the following exceeds the standard line height. This
+forces \TEX\ to insert \type {\lineskip} (mentioned in the demonstration
+paragraph above), a dimension that is normally set to a fraction of the line
+spacing (for instance 1pt for a 10pt body font and 12pt line spacing). When we
+are profiling, \type{\lineskip} is ignored and we use a settable distance
+instead. The second example (with superscripts) normally comes out fine as the
+math stays within limits and we make sure that smaller fractions and scripts stay
+within the natural limits of the line, but nested scripts can be an issue.

+
+In \in {figure} [fig:profiling:zapf] we see the profile of a regular text with no
+math. The average text stays well within the limits of height and depth. If this
+doesn't happen for prose then you need to adapt the height|/|depth ratio to the
+ascender|/|descender ratio of the bodyfont. For regular text it makes no sense to
+use the profiler, it only slows down typesetting.

+of profiling currently implemented. (This is still experimental code so there
+might be more in the future). Seeing profiles helps to get a picture of the
+complications we have to deal with. In addition to the normal \type {vbox}
+variant (used in the previous examples), we show \type {none} which only
+analyzes, \type {strict} that uses the natural dimensions of lines and \type
+{fixed} that is supposed to cooperate with grid snapping.

+\in {Figure} [fig:profiling:simple-text] we show what happens when we add some

+
+\starttyping

+
+and:

+\stoptyping
+
+Here the \type {strict} variant has some effect while \type {fixed} only has some
+influence on the height and depth of lines. Later we will see that \type {fixed}
+operates in steps and the default step is large so here we never meet the
+criteria for closing up. \footnote {In \CONTEXT\ we normally use \type {\high}
+and \type {\low} and both ensure that we don't exceed the natural height and
+depth.}
+
+A profiled box is typeset with \type {\profiledbox}. There is some control
+possible but the options are not yet set in stone so we won't use them all here.
+Profiling can be turned on for the whole document with \type {\setprofile} but
+I'm sure that will seldom happen, and these examples show why: one cannot
+beforehand say if the result looks good. Let's now apply profiling to a real
+text. If you play with this yourself you can show profiles in gray with a
+tracker:

+
+We show the effects of setting distances in \in {figure}
+[fig:profiling:distances]. We start with a zero distance:
+
+\typebuffer[raw-1]
+
+Because we don't want lines to touch we then set the minimum distance to a
+reasonable value (1pt).
+
+\typebuffer[raw-2]
+
+Finally we also double the height and depth of lines, something that normally will
+not be done. The defaults are the standard height and depth (the ones you get
+when you inject a so-called \type{\strut}).
+
+\typebuffer[raw-3]
+
+The problem with this kind of analysis is that deciding when and how to use this
+information to improve spacing is non|-|trivial. One of the characteristics of
+user demand is that it nearly always concerns rather specific situations and that
+suggested solutions could work only in those cases. But as soon as we have one
+exceptional situation, intervention is needed which in turn means that a
+mechanism has to be under complete user control. That itself assumes that the
+user still has control, which is not the case in automated workflows. In fact, as
+soon as one is in control over the source and rendering, there are often easier
+ways to deal with the few cases that need treatment. Possible interference can
+come from, for instance:
+
+\startitemize[packed]
+\startitem whitespace between paragraphs \stopitem
+\startitem section titles (using different fonts and spacing) \stopitem
+\startitem descriptions and other intermezzos \stopitem
+\startitem images that interrupt the flow, or end up next to text \stopitem
+\startitem ornaments like margin words (we catch some) \stopitem
+\startitem text backgrounds making spacing assumptions \stopitem
+\stopitemize
+
+After a few decades of using \TEX\ and writing solutions, it has become pretty
+clear that fully automated typesetting is a dream, if only because the input can
+be pretty weird and inconsistent and demands (from those who are accustomed to
+tweaking manually in a desktop publishing application) can be pretty weird and
+inconsistent too. So, the only real solution is to use some kind of artificial
+intelligence that one can feed with demands and constraints and that hopefully is
+clever enough to deal with the inconsistencies. As this kind of computing is
+unlikely to happen in my lifetime, poor man explicit solutions have to do the job
+for now. One can add all kinds of heuristics to the profiler but this can
+backfire when control is needed. Alternatively one can end up with many options
+like we have in grid snapping.
+
+\stopsection
+
+\startsection[title=Where to use profiling]
+
+In \CONTEXT\ there are four places (maybe a few more eventually) where this kind
+of control over spacing makes sense:
+
+\startitemize[packed]
+\startitem the main text flow in single column mode \stopitem
+\startitem multi|-|column mode, especially mixed columns \stopitem
+\startitem framed texts, used for all kinds of content \stopitem
+\startitem explicitly (balanced) split boxes \stopitem
+\stopitemize
+
+Because framed texts are used all over, for instance in tables, it means that if
+we provide control over spacing using profiles, many \CONTEXT\ mechanisms can use
+it. However, enabling this for all packaging has a significant overhead so it has
+to be used with care so that there is no performance hit when it is not used.
+Here is an easy example using \type {\framed}:
+
+\starttyping
+\framed
+  [align=normal,
+   profile=fixed,
+   frame=off]
+  {some text ...}
+\stoptyping
+
+For the following examples we define this helper:
+
+\startbuffer
+\starttexdefinition demo-profile-1 #1
+  \framed
+    [align=normal,profile=#1]
+    {xxx$\frac{1}{\frac{1}{\frac{1}{2}}}$
+     \par
+     $\frac{\frac{1}{\frac{1}{2}}}{2}$xxx}
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We apply this to predefined profiles. The macro is called like this:
+
+\starttyping
+\texdefinition{demo-profile-1}{fixed}
+\stoptyping
+
+\starttexdefinition unexpanded ProfileSteps #1
+    \startcombination[nx=5,ny=1]
+        {#1\hbox to 6em{\hss\texdefinition{demo-profile-1}            {}\hss}} {\small vbox}
+        {#1\hbox to 6em{\hss\texdefinition{demo-profile-1}       {fixed}\hss}} {\small\type{fixed}}
+        {#1\hbox to 6em{\hss\texdefinition{demo-profile-1}   {halffixed}\hss}} {\small\type{halffixed}}
+        {#1\hbox to 6em{\hss\texdefinition{demo-profile-1}{quarterfixed}\hss}} {\small\type{quarterfixed}}
+        {#1\hbox to 6em{\hss\texdefinition{demo-profile-1} {eightsfixed}\hss}} {\small\type{eightsfixed}}
+    \stopcombination
+\stoptexdefinition
+
+The outcome can depend on the font used: in \in {figure}
+[fig:profiling:profiles-fonts] we show Latin Modern, \TEX\ Gyre Pagella and
+Dejavu. Because in \CONTEXT\ the line height depends on the bodyfont; each case
+is different.

+
+As mentioned, we need this kind of profiling in multi|-|column typesetting, so
+let us have a look at that now. Columns are processed in grid mode but this is
+taken into account. We can simulate this by using boxed columns; see \in {figure}
+[fig:profiling:profiles-boxedcolumns]. One of the biggest problems is what to do
+with the bottom and top of a page or column. This will probably take a bit more
+to get right, and likely we will end up with different strategies. We can also
+think of special handlers but that will come with a high speed penalty. In the
+\type {strict} variant we don't mess with the dimension of a line too much, but
+the \type {fixed} alternative will get some more control.
+
+Although using this feature looks promising it is also dangerous. For instance a
+side effect can be that interline spacing becomes inconsistent and even ugly. It
+really depends on the content. Also, as soon as some grid snapping is used, the
+gain becomes less, simply because the solution space is smaller. Then of course
+there is the matter of overall look and feel: most documents that need this kind
+of magic look bad anyway, so why bother. In this respect it is comparable to
+applying protrusion and expansion. There are hardly any combinations of design
+and content where micro|-|typography makes sense to use: in prose perhaps, but
+not in mixed content. On the other hand, profiling makes more sense in mixed
+content than in prose.
+
+Not everything that is possible should be used. In \in {figure}
+[fig:profiling:fake-examples-1] we show some fake paragraphs with profiles
+applied, the first series (random range~2) has a few excessive snippets, the last
+one (random range~5) has many. In \in {figure} [fig:profiling:fake-examples-2] we
+show them in a different arrangement. Although there are differences it is hard
+to say if the results look better. We scaled down the results and used gray fake
+blurs instead of real text in order to get a better impression of the so-called
+(overall) grayness of a text.

+\startsection[title=Conclusion]
+
+Although profiling seems interesting, in practice it does not have much value in
+an automated flow. Ultimately, in the project for which I investigated this
+trickery, only in the final stage was some last minute optimization of the
+rendering done. We did that by injecting directives. Think of page breaks that
+make the result look more balanced. Optimizing image placement happens in an
+earlier stage because the text can refer to images like \quotation {in the
+picture on the left, we see \unknown}. Controlling profiles is much harder. In
+fact, the more clever we are, the harder it gets to beat it when we want an
+exception. All these mechanisms: spacing, snapping, profiling, breaking pages,
+image placement, to mention a few, have to work together. For projects that
+depend on such placement, it might be better to write dedicated mechanisms than
+to try to fight with clever built|-|in features.
+
+In practice, probably only the \type {fixed} alternative makes sense and as that
+one has a boundary condition similar to (or equal, depending on other settings)
+snapping on gridsteps, the end result might not be that different from doing
+nothing. In \in {figure} [fig:profiling:fake-examples-3] you see that the vbox
+variant is not that bad. And extremely difficult content is unlikely to ever look
+perfect unless some manual intervention happens. Therefore, from the perspective
+of \quotation {fine points of text typesetting} some local (manual) control might
+be more interesting and relevant.
+
+\texdefinition{profile-sample-set}{0}{3}{FakeGreen}
+\texdefinition{profile-sample-set}{2}{3}{FakeGreen}
+\texdefinition{profile-sample-set}{4}{3}{FakeGreen}
+
+In the end, I didn't need this profiling feature at all: because there are
+expectations with respect to how many pages a book should have, typesetting in
+columns was not needed. It didn't save that many pages, and the result would
+never look that much better, simply because of the type of content. Large images
+were also spoiling the game. Nevertheless we will keep profiles in the core and
+it might even get extended. One question remains: at what point do we stop adding
+such features? The answer would be easier if \TEX\ wasn't so flexible.

+\startchapter[title=Removing something (typeset)]
+
+\startsection[title=Introduction]
+
+The primitive \type {\unskip} often comes in handy when you want to remove a
+space (or more precisely: a glue item) but sometimes you want to remove more.
+Consider for instance the case where a sentence is built up stepwise from data.
+At some point you need to insert some punctuation but as you cannot look ahead it
+needs to be delayed. Keeping track of accumulated content is no fun, and a quick
+and dirty solution is to just inject it and remove it when needed. One way to
+achieve this is to wrap this optional content in a box with special dimensions.
+Just before the next snippet is injected we can look back for that box (that can
+then be recognized by those special dimensions) and either remove it or unbox it
+back into the stream.
+
+To be honest, one seldom needs this feature. In fact I never needed it until
+Alan Braslau and I were messing around with (indeed messy) bibliographic
+rendering and we thought it would be handy to have a helper that could remove
+punctuation. Think of situations like this:
+
+\starttyping
+John Foo, Mary Bar and others.
+John Foo, Mary Bar, and others.
+\stoptyping
+
+One can imagine this list to be constructed programmatically, in which case the
+comma before the \type {and} can be superfluous. So, the \type {and others} can
+be done like this:
+
+\startbuffer
+\def\InjectOthers
+  {\removeunwantedspaces
+   \removepunctuation
+   \space and others}
+
+John Foo, Mary Bar, \InjectOthers.
+\stopbuffer
+
+\typebuffer
+
+Notice that we first remove spaces. This will give:
+
+\blank {\bf \getbuffer} \blank
+
+where the commas after the names are coming from some not|-|too|-|clever automatism
+or are the side effect of lazy programming. In the sections below I will describe
+a bit more generic mechanism and also present a solution for non|-|\CONTEXT\ users.
+
+\stopsection
+
+\startsection[title=Marked content]
+
+The example above can be rewritten in a more general way. We define a
+couple macros (using \CONTEXT\ functionality):
+
+\startbuffer
+\def\InjectComma
+  {\markcontent
+     [punctuation]
+     {\removeunwantedspaces,\space}}
+
+\def\InjectOthers
+  {\removemarkedcontent[punctuation]%
+   \space and others}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+These can be used as:
+
+\startbuffer
+John Foo\InjectComma Mary Bar\InjectComma \InjectOthers.
+\stopbuffer
+
+\typebuffer
+
+Which gives us:
+
+\blank {\bf \getbuffer} \blank
+
+Normally one doesn't need this kind of magic for lists because the length of the
+list is known and injection can be done using the index in the list. Here is a more 
+practical example:
+
+\startbuffer
+\def\SomeTitle {Just a title}
+\def\SomeAuthor{Just an author}
+\def\SomeYear  {2015}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We paste the three snippets together:
+
+\startbuffer
+\SomeTitle,\space \SomeAuthor\space (\SomeYear).
+\stopbuffer
+
+\typebuffer \blank {\bf \getbuffer} \blank
+
+But to get even more abstract, we can do this:
+
+\startbuffer
+\def\PlaceTitle
+  {\SomeTitle
+   \markcontent[punctuation]{.}}
+
+\def\PlaceAuthor
+  {\removemarkedcontent[punctuation]%
+   \markcontent[punctuation]{,\space}%
+   \SomeAuthor
+   \markcontent[punctuation]{,\space}}
+
+\def\PlaceYear
+  {\removemarkedcontent[punctuation]%
+   \space(\SomeYear)%
+   \markcontent[punctuation]{.}}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Used as:
+
+\startbuffer
+\PlaceTitle\PlaceAuthor\PlaceYear
+\stopbuffer
+
+\typebuffer
+
+we get the output:
+
+\blank {\bf \getbuffer} \blank
+
+but when we have no author,
+
+\startbuffer
+\def\SomeAuthor{}
+
+\PlaceTitle\PlaceAuthor\PlaceYear
+\stopbuffer
+
+\typebuffer
+
+Now we get:
+
+\blank {\bf \getbuffer} \blank
+
+Even more clever is this:
+
+\def\PlaceYear
+  {\removemarkedcontent[punctuation]%
+   \markcontent[punctuation]{\space(\SomeYear).}}
+
+\startbuffer
+\def\SomeAuthor{}
+\def\SomeYear{}
+\def\SomePeriod{\removemarkedcontent[punctuation].}
+
+\PlaceTitle\PlaceAuthor\PlaceYear\SomePeriod
+\stopbuffer
+
+\typebuffer
+
+The output is:
+
+\blank {\bf \getbuffer} \blank
+
+Of course we can just test for a variable like \type {\SomeAuthor} being empty
+before we place punctuation, but there are cases where a period becomes a comma
+or a comma becomes a semicolon. Especially with bibliographies your worst
+typographical nightmares come true, so it is handy to have such a mechanism
+available when it's needed.
+
+\stopsection
+
+\startsection[title=A plain solution]
+
+For users of \LUATEX\ who don't want to use \CONTEXT\ I will now present an
+alternative implementation. Of course more clever variants are possible but the
+principle remains. The trick is simple enough to show here as an example of \LUA\
+coding as it doesn't need much help from the infrastructure that the macro
+package provides. The only pitfall is the used signal (attribute number) but you
+can set another one if needed. We use the \type {gadgets} namespace to isolate
+the code.
+
+\startbuffer
+\directlua {
+  gadgets         = gadgets or { }
+  local marking   = { }
+  gadgets.marking = marking
+
+  local marksignal   = 5001
+  local lastmarked   = 0
+  local marked       = { }
+  local local_par    = 6
+  local whatsit_node = 8
+
+  function marking.setsignal(n)
+    marksignal = tonumber(n) or marksignal
+  end
+
+  function marking.mark(str)
+    local currentmarked = marked[str]
+    if not currentmarked then
+      lastmarked    = lastmarked + 1
+      currentmarked = lastmarked
+      marked[str]   = currentmarked
+    end
+    tex.setattribute(marksignal,currentmarked)
+  end
+
+  function marking.remove(str)
+    local attr = marked[str]
+    if not attr then
+      return
+    end
+    local list = tex.nest[tex.nest.ptr]
+    if list then
+      local head = list.head
+      local tail = list.tail
+      local last = tail
+      if last[marksignal] == attr then
+        local first = last
+        while true do
+          local prev = first.prev
+          if not prev or prev[marksignal] ~= attr or
+               (prev.id == whatsit_node and
+                  prev.subtype == local_par) then
+             break
+          else
+            first = prev
+          end
+        end
+        if first == head then
+          list.head = nil
+          list.tail = nil
+        else
+          local prev = first.prev
+          list.tail  = prev
+          prev.next  = nil
+        end
+        node.flush_list(first)
+      end
+    end
+  end
+}
+\stopbuffer
+\stopluacode
+
+\typebuffer \getbuffer
+
+These functions are called from macros. We use symbolic names for the marked
+snippets. We could have used numbers but meaningful tags can be supported with
+negligible overhead. The remover starts at the end of the current list and
+goes backwards till no matching attribute value is seen. When a valid range is
+found it gets removed.
+
+\startbuffer
+\def\setmarksignal#1%
+  {\directlua{gadgets.marking.setsignal(\number#1)}}
+
+\def\marksomething#1#2%
+  {{\directlua{gadgets.marking.mark("#1")}{#2}}}
+
+\def\unsomething#1%
+  {\directlua{gadgets.marking.remove("#1")}}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The working of these macros can best be shown from a few examples:
+
+\startbuffer
+before\marksomething{gone}{\em HERE}\unsomething{gone}after
+before\marksomething{kept}{\em HERE}\unsomething{gone}after
+\marksomething{gone}{\em HERE}\unsomething{gone}last
+\marksomething{kept}{\em HERE}\unsomething{gone}last
+\stopbuffer
+
+\typebuffer
+
+This renders as: \blank \startlines\bf\getbuffer\stoplines
+
+The remover needs to look at the beginning of a paragraph marked by a local par
+whatsit. If we removed that, \LUATEX\ would crash because the list head
+(currently) cannot be set to nil. This is no big deal because this macro is not
+meant to clean up across paragraphs.
+
+A close look at the definition of \type {\marksomething} will reveal
+an extra grouping in the definition. This is needed to make content that uses
+\type {\aftergroup} trickery work correctly. Here is another example:
+
+\startbuffer
+\def\SnippetOne  {first\marksomething{punctuation}{, }}
+\def\SnippetTwo  {second\marksomething{punctuation}{, }}
+\def\SnippetThree{\unsomething{punctuation} and third.}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can paste these snippets together and make the last one use \type {and}
+instead of a comma.
+
+\startbuffer
+\SnippetOne \SnippetTwo  \SnippetThree\par
+\SnippetOne \SnippetThree\par
+\stopbuffer
+
+\typebuffer
+
+We get: \blank {\bf \getbuffer} \blank
+
+Of course in practice one probably knows how many snippets there are and using a
+counter to keep track of the state is more efficient than first typesetting
+something and removing it afterwards. But still it looks like a cool feature and
+it can come in handy at some point, as with the title|-|author|-|year example given
+before.
+
+The plain code shown here is in the distribution in the file \type
+{luatex-gadgets} and gets preloaded in the \type {luatex-plain} format.

+\startchapter[title=Scanning input]
+
+\startsection[title=Introduction]
+
+Tokens are the building blocks of the input for \TEX\ and they drive the process
+of expansion which in turn results in typesetting. If you want to manipulate the
+input, intercepting tokens is one approach. Other solutions are preprocessing or
+writing macros that do something with their picked|-|up arguments. In \CONTEXT\
+\MKIV\ we often forget about manipulating the input but manipulate the
+intermediate typesetting results instead. The advantage is that only at that
+moment do you know what you're truly dealing with, but a disadvantage is that
+parsing the so-called node lists is not always efficient and it can even be
+rather complex, for instance in math. It remains a fact that until \LUATEX\
+version 0.80 \CONTEXT\ hardly used the token interface.
+
+In version 0.80 a new scanner interface was introduced, demonstrated by Taco
+Hoekwater at the \CONTEXT\ conference 2014. Luigi Scarso and I integrated that
+code and I added a few more functions. Eventually the team will kick out the old
+token library and overhaul the input|-|related code in \LUATEX, because no
+callback is needed any more (and also because the current code still has traces
+of multiple \LUA\ instances). This will happen stepwise to give users who use the
+old mechanism an opportunity to adapt.
+
+Here I will show a bit of the new token scanners and explain how they can be used
+in \CONTEXT. Some of the additional scanners written on top of the built|-|in ones
+will probably end up in the generic \LUATEX\ code that ships with \CONTEXT.
+
+\stopsection
+
+\startsection[title=The \TEX\ scanner]
+
+The new token scanner library of \LUATEX\ provides a way to hook \LUA\ into \TEX\
+in a rather natural way. I have to admit that I never had any real demand for
+such a feature but now that we have it, it is worth exploring.
+
+The \TEX\ scanner roughly provides the following sub-scanners that are used to
+implement primitives: keyword, token, token list, dimension, glue and integer.
+Deep down there are specific variants for scanning, for instance, font dimensions
+and special numbers.
+
+A token is a unit of input, and one or more characters are turned into a token.
+How a character is interpreted is determined by its current catcode. For instance
+a backslash is normally tagged as `escape character' which means that it starts a
+control sequence: a macro name or primitive. This means that once it is scanned a
+macro name travels as one token through the system. Take this:
+
+\starttyping
+\def\foo#1{\scratchcounter=123#1\relax}
+\stoptyping
+
+Here \TEX\ scans \type {\def} and turns it into a token. This particular token
+triggers a specific branch in the scanner. First a name is scanned with
+optionally an argument specification. Then the body is scanned and the macro is
+stored in memory. Because \type {\scratchcounter}, \type
+{\relax} and \type {#1} are
+turned into tokens, this body has 7~tokens.
+
+When the macro \type {\foo} is referenced the body gets expanded which here means
+that the scanner will scan for an argument first and uses that in the
+replacement. So, the scanner switches between different states. Sometimes tokens
+are just collected and stored, in other cases they get expanded immediately into
+some action.
+
+\stopsection
+
+\startsection[title=Scanning from \LUA]
+
+The basic building blocks of the scanner are available at the \LUA\ end, for
+instance:
+
+\starttyping
+\directlua{print(token.scan_int())} 123
+\stoptyping
+
+This will print \type {123} to the console. Or, you can store the number and
+use it later:
+
+\starttyping
+\directlua{SavedNumber = token.scan_int())} 123
+
+We saved: \directlua{tex.print(SavedNumber)}
+\stoptyping
+
+The number of scanner functions is (on purpose) limited but you can use them to
+write additional ones as you can just grab tokens, interpret them and act
+accordingly.
+
+The \type {scan_int} function picks up a number. This can also be a counter, a
+named (math) character or a numeric expression. In \TEX, numbers are integers;
+floating|-|point is not supported naturally. With \type {scan_dimen} a dimension
+is grabbed, where a dimen is either a number (float) followed by a unit, a dimen
+register or a dimen expression (internally, all become integers). Of course
+internal quantities are also okay. There are two optional arguments, the first
+indicating that we accept a filler as unit, while the second indicates that math
+units are expected. When an integer or dimension is scanned, tokens are expanded
+till the input is a valid number or dimension. The \type {scan_glue} function
+takes one optional argument: a boolean indicating if the units are math.
+
+The \type {scan_toks} function picks up a (normally) brace|-|delimited sequence of
+tokens and (\LUATEX\ 0.80) returns them as a table of tokens. The function \type
+{get_token} returns one (unexpanded) token while \type {scan_token} returns
+an expanded one.
+
+Because strings are natural to \LUA\ we also have \type {scan_string}. This one
+converts a following brace|-|delimited sequence of tokens into a proper string.
+
+The function \type {scan_keyword} looks for the given keyword and when found skips
+over it and returns \type {true}. Here is an example of usage: \footnote {In
+\LUATEX\ 0.80 you should use \type {newtoken} instead of \type {token}.}
+
+\starttyping
+function ScanPair()
+  local one = 0
+  local two = ""
+  while true do
+    if token.scan_keyword("one") then
+      one = token.scan_int()
+    elseif token.scan_keyword("two") then
+      two = token.scan_string()
+    else
+      break
+    end
+  end
+  tex.print("one: ",one,"\\par")
+  tex.print("two: ",two,"\\par")
+end
+\stoptyping
+
+This can be used as:
+
+\starttyping
+\directlua{ScanPair()}
+\stoptyping
+
+You can scan for an explicit character (class) with \type {scan_code}. This
+function takes a positive number as argument and returns a character or \type
+{nil}.

+
+When no argument is given, the next character with catcode letter or other is

+
+In \CONTEXT\ we use the \type {tokens} namespace which has additional scanners

+
+All except \type {get_token} (or its alias \type {getters.token}) expand tokens
+in order to satisfy the demands.
+
+Here are some examples of how we can use the scanners. When we would call
+\type {Foo} with regular arguments we do this:
+
+\starttyping
+\def\foo#1{%
+  \directlua {
+    Foo("whatever","#1",{n = 1})
+  }
+}
+\stoptyping
+
+but when \type {Foo} uses the scanners it becomes:
+
+\starttyping
+\def\foo#1{%
+  \directlua{Foo()} {whatever} {#1} n {1}\relax
+}
+\stoptyping
+
+In the first case we have a function \type {Foo} like this:
+
+\starttyping
+function Foo(what,str,n)
+  --
+  -- do something with these three parameters
+  --
+end
+\stoptyping
+
+and in the second variant we have (using the \type {tokens} namespace):
+
+\starttyping
+function Foo()
+  local what = tokens.scanners.string()
+  local str  = tokens.scanners.string()
+  local n    = tokens.scanners.keyword("n") and
+               tokens.scanners.integer() or 0
+  --
+  -- do something with these three parameters
+  --
+end
+\stoptyping
+
+The string scanned is kind of special as the result depends ok what is seen.
+Given the following definition:
+
+\startbuffer
+           \def\bar  {bar}
+\unexpanded\def\ubar {ubar} % \protected in plain etc
+           \def\foo  {foo-\bar-\ubar}
+           \def\wrap {{foo-\bar}}
+           \def\uwrap{{foo-\ubar}}
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We get:
+
+\def\TokTest{\ctxlua{
+    local s = tokens.scanners.string()
+    context("\\bgroup\\red\\tt")
+    context.verbatim(s)
+    context("\\egroup")
+}}

+\stoptabulate
+
+Because scanners look ahead the following happens: when an open brace is seen (or
+any character marked as left brace) the scanner picks up tokens and expands them
+unless they are protected; so, effectively, it scans as if the body of an \type
+{\edef} is scanned. However, when the next token is a control sequence it will be
+expanded first to see if there is a left brace, so there we get the full
+expansion. In practice this is convenient behaviour because the braced variant
+permits us to pick up meanings honouring protection. Of course this is all a side
+effect of how \TEX\ scans.\footnote {This lookahead expansion can sometimes give
+unexpected side effects because often \TEX\ pushes back a token when a condition
+is not met. For instance when it scans a number, scanning stops when no digits
+are seen but the scanner has to look at the next (expanded) token in order to
+come to that conclusion. In the process it will, for instance, expand
+conditionals. This means that intermediate catcode changes will not be effective
+(or applied) to already-seen tokens that were pushed back into the input. This
+also happens with, for instance, \cs {futurelet}.}
+
+With the braced variant one can of course use primitives like \type {\detokenize}
+and \type {\unexpanded} (in \CONTEXT: \type {\normalunexpanded}, as we already
+had this mechanism before it was added to the engine).
+
+\stopsection
+
+\startsection[title=Considerations]
+
+Performance|-|wise there is not much difference between these methods. With some
+effort you can make the second approach faster than the first but in practice you
+will not notice much gain. So, the main motivation for using the scanner is that
+it provides a more \TEX|-|ified interface. When playing with the initial version
+of the scanners I did some tests with performance|-|sensitive \CONTEXT\ calls and
+the difference was measurable (positive) but deciding if and when to use the
+scanner approach was not easy. Sometimes embedded \LUA\ code looks better, and
+sometimes \TEX\ code. Eventually we will end up with a mix. Here are some
+considerations:
+
+\startitemize
+\startitem
+    In both cases there is the overhead of a \LUA\ call.
+\stopitem
+\startitem
+    In the pure \LUA\ case the whole argument is tokenized by \TEX\ and then
+    converted to a string that gets compiled by \LUA\ and executed.
+\stopitem
+\startitem
+    When the scan happens in \LUA\ there are extra calls to functions but
+    scanning still happens in \TEX; some token to string conversion is avoided
+    and compilation can be more efficient.
+\stopitem
+\startitem
+    When data comes from external files, parsing with \LUA\ is in most cases more
+    efficient than parsing by \TEX .
+\stopitem
+\startitem
+    A macro package like \CONTEXT\ wraps functionality in macros and is
+    controlled by key|/|value specifications. There is often no benefit in terms
+    of performance when delegating to the mentioned scanners.
+\stopitem
+\stopitemize
+
+Another consideration is that when using macros, parameters are often passed
+between \type {{}}:
+
+\starttyping
+\def\foo#1#2#3%
+  {...}
+\foo {a}{123}{b}
+\stoptyping
+
+and suddenly changing that to
+
+\starttyping
+\def\foo{\directlua{Foo()}}
+\stoptyping
+
+and using that as:
+
+\starttyping
+\foo {a} {b} n 123
+\stoptyping
+
+means that \type {{123}} will fail. So, eventually you will end up with something:
+
+\starttyping
+\def\myfakeprimitive{\directlua{Foo()}}
+\def\foo#1#2#3{\myfakeprimitive {#1} {#2} n #3 }
+\stoptyping
+
+and:
+
+\starttyping
+\foo {a} {b} {123}
+\stoptyping
+
+So in the end you don't gain much here apart from the fact that the fake
+primitive can be made more clever and accept optional arguments. But such new
+features are often hidden for the user who uses more high|-|level wrappers.
+
+When you code in pure \TEX\ and want to grab a number directly you need to test
+for the braced case; when you use the \LUA\ scanner method you still need to test
+for braces. The scanners are consistent with the way \TEX\ works. Of course you
+can write helpers that do some checking for braces in \LUA, so there are no real
+limitations, but it adds some overhead (and maybe also confusion).
+
+One way to speed up the call is to use the \type {\luafunction} primitive in
+combinations with predefined functions and although both mechanisms can benefit
+from this, the scanner approach gets more out of that as this method cannot be
+used with regular function calls that get arguments. In (rather low level) \LUA\
+it looks like this:
+
+\starttyping
+luafunctions[1] = function()
+  local a token.scan_string()
+  local n token.scan_int()
+  local b token.scan_string()
+  -- whatever --
+end
+\stoptyping
+
+And in \TEX:
+
+\starttyping
+\luafunction1 {a} 123 {b}
+\stoptyping
+
+This can of course be wrapped as:
+
+\starttyping
+\def\myprimitive{\luafunction1 }
+\stoptyping
+
+\stopsection
+
+\startsection[title=Applications]
+
+The question now pops up: where can this be used? Can you really make new
+primitives? The answer is yes. You can write code that exclusively stays on the
+\LUA\ side but you can also do some magic and then print back something to \TEX.
+Here we use the basic token interface, not \CONTEXT:
+
+\startbuffer
+\directlua {
+local token = newtoken or token
+function ColoredRule()
+  local w, h, d, c, t
+  while true do
+    if token.scan_keyword("width") then
+      w = token.scan_dimen()
+    elseif token.scan_keyword("height") then
+      h = token.scan_dimen()
+    elseif token.scan_keyword("depth") then
+      d = token.scan_dimen()
+    elseif token.scan_keyword("color") then
+      c = token.scan_string()
+    elseif token.scan_keyword("type") then
+      t = token.scan_string()
+    else
+      break
+    end
+  end
+  if c then
+    tex.sprint("\\color[",c,"]{")
+  end
+  if t == "vertical" then
+    tex.sprint("\\vrule")
+  else
+    tex.sprint("\\hrule")
+  end
+  if w then
+    tex.sprint("width ",w,"sp")
+  end
+  if h then
+    tex.sprint("height ",h,"sp")
+  end
+  if d then
+    tex.sprint("depth ",d,"sp")
+  end
+  if c then
+    tex.sprint("\\relax}")
+  end
+end
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This can be given a \TeX\ interface like:
+
+\startbuffer
+\def\myhrule{\directlua{ColoredRule()} type {horizontal} }
+\def\myvrule{\directlua{ColoredRule()} type {vertical} }
+\stopbuffer
+
+\typebuffer \getbuffer
+
+And used as:
+
+\startbuffer
+\myhrule width \hsize height 1cm color {darkred}
+\stopbuffer
+
+\typebuffer
+
+giving:
+
+% when no newtokens:
+%
+% \startbuffer
+% \blackrule[width=\hsize,height=1cm,color=darkred]
+% \stopbuffer
+
+\startlinecorrection \getbuffer \stoplinecorrection
+
+Of course \CONTEXT\ users can use the following commands to color an

+
+\startbuffer
+\blackrule[width=\hsize,height=1cm,color=darkgreen]
+\stopbuffer
+
+\typebuffer \startlinecorrection \getbuffer \stoplinecorrection
+
+The official \CONTEXT\ way to define such a new command is the following. The
+conversion back to verbose dimensions is needed because we pass back to \TEX.
+
+\startbuffer
+\startluacode
+local myrule = tokens.compile {
+  {
+    { "width",  "dimension", "todimen" },
+    { "height", "dimension", "todimen" },
+    { "depth",  "dimension", "todimen" },
+    { "color",  "string" },
+    { "type",   "string" },
+  }
+}
+
+interfaces.scanners.ColoredRule = function()
+  local t = myrule()
+  context.blackrule {
+    color  = t.color,
+    width  = t.width,
+    height = t.height,
+    depth  = t.depth,
+  }
+end
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+With:
+
+\startbuffer
+\unprotect \let\myrule\clf_ColoredRule \protect
+\stopbuffer
+
+\typebuffer \getbuffer
+
+and
+
+\startbuffer
+\myrule width \textwidth height 1cm color {maincolor} \relax
+\stopbuffer
+
+\typebuffer
+
+we get:
+
+% when no newtokens:
+%
+% \startbuffer
+% \blackrule[width=\hsize,height=1cm,color=maincolor]
+% \stopbuffer
+
+\startlinecorrection \getbuffer \stoplinecorrection
+
+There are many ways to use the scanners and each has its charm. We will look at
+some alternatives from the perspective of performance. The timings are more meant
+as relative measures than absolute ones. After all it depends on the hardware. We
+assume the following shortcuts:
+
+\starttyping
+local scannumber  = tokens.scanners.number
+local scankeyword = tokens.scanners.keyword
+local scanword    = tokens.scanners.word
+\stoptyping
+
+We will scan for four different keys and values. The number is scanned using a
+helper \type {scannumber} that scans for a number that is acceptable for \LUA.
+Thus, \type {1.23} is valid, as are \type {0x1234} and \type {12.12E4}.
+
+% interfaces.scanners.test_scaling_a

+\starttyping
+function getmatrix()
+  local sx, sy = 1, 1
+  local rx, ry = 0, 0
+  while true do
+    if scankeyword("sx") then
+      sx = scannumber()
+    elseif scankeyword("sy") then
+      sy = scannumber()
+    elseif scankeyword("rx") then
+      rx = scannumber()
+    elseif scankeyword("ry") then

+    else

+\stoptyping
+
+Scanning the following specification  100000 times takes 1.00 seconds:
+
+\starttyping
+sx 1.23 sy 4.5 rx 1.23 ry 4.5
+\stoptyping
+
+The \quote {tight} case takes 0.94 seconds:
+
+\starttyping
+sx1.23 sy4.5 rx1.23 ry4.5
+\stoptyping
+
+% interfaces.scanners.test_scaling_b
+
+We can compare this to scanning without keywords. In that case there have to be
+exactly four arguments. These have to be given in the right order which is no big
+deal as often such helpers are encapsulated in a user|-|friendly macro.
+
+\starttyping
+function getmatrix()
+  local sx, sy = scannumber(), scannumber()
+  local rx, ry = scannumber(), scannumber()
+  -- action --
+end
+\stoptyping
+
+As expected, this is more efficient than the previous examples. It takes 0.80
+seconds to scan this 100000 times:
+
+\starttyping
+1.23 4.5 1.23 4.5
+\stoptyping
+
+A third alternative is the following:
+
+\starttyping
+function getmatrix()
+  local sx, sy = 1, 1
+  local rx, ry = 0, 0
+  while true do
+    local kw = scanword()
+    if kw == "sx" then
+      sx = scannumber()
+    elseif kw == "sy" then
+      sy = scannumber()
+    elseif kw == "rx" then
+      rx = scannumber()
+    elseif kw == "ry" then
+      ry = scannumber()
+    else
+      break
+    end
+  end
+  -- action --
+end
+\stoptyping
+
+Here we scan for a keyword and assign a number to the right variable. This one
+call happens to be less efficient than calling \type {scan_keyword} 10 times
+($4+3+2+1$) for the explicit scan. This run takes 1.11 seconds for the next line.
+The spaces are really needed as words can be anything that has no space.
+\footnote {Hard|-|coding the word scan in a \CCODE\ helper makes little sense, as
+different macro packages can have different assumptions about what a word is. And
+we don't extend \LUATEX\ for specific macro packages.}
+
+\starttyping
+sx 1.23 sy 4.5 rx 1.23 ry 4.5
+\stoptyping
+
+Of course these numbers need to be compared to a baseline of no scanning (i.e.\
+the overhead of a \LUA\ call which here amounts to 0.10 seconds. This brings
+us to the following table.
+
+\starttabulate[|l|l|]
+\NC keyword checks \NC 0.9 sec\NC \NR
+\NC no keywords    \NC 0.7 sec\NC \NR
+\NC word checks    \NC 1.0 sec\NC \NR
+\stoptabulate
+
+The differences are not that impressive given the number of calls. Even in a
+complex document the overhead of scanning can be negligible compared to the
+actions involved in typesetting the document. In fact, there will always be some
+kind of scanning for such macros so we're talking about even less impact. So you
+can just use the method you like most. In practice, the extra overhead of using
+keywords in combination with explicit checks (the first case) is rather
+convenient.
+
+If you don't want to have many tests you can do something like this:
+
+\starttyping
+local keys = {
+  sx = scannumber, sy = scannumber,
+  rx = scannumber, ry = scannumber,
+}
+
+function getmatrix()
+  local values = { }
+  while true do
+    for key, scan in next, keys do
+      if scankeyword(key) then
+        values[key] = scan()
+      else
+        break
+      end
+    end
+  end
+  -- action --
+end
+\stoptyping
+
+This is still quite fast although one now has to access the values in a table.
+Working with specifications like this is clean anyway so in \CONTEXT\ we have a
+way to abstract the previous definition.
+
+\starttyping
+local specification = tokens.compile {
+  {
+    { "sx", "number" }, { "sy", "number" },
+    { "rx", "number" }, { "ry", "number" },
+  },
+}
+
+function getmatrix()
+  local values = specification()
+  -- action using values.sx etc --
+end
+\stoptyping
+
+Although one can make complex definitions this way, the question remains if it
+is a better approach than passing \LUA\ tables. The standard \CONTEXT\ way for
+controlling features is:
+
+\starttyping
+\getmatrix[sx=1.2,sy=3.4]
+\stoptyping
+
+So it doesn't matter much if deep down we see:
+
+\starttyping
+\def\getmatrix[#1]%
+  {\getparameters[@@matrix][sx=1,sy=1,rx=1,ry=1,#1]%
+   \domatrix
+     \@@matrixsx
+     \@@matrixsy
+     \@@matrixrx
+     \@@matrixry
+   \relax}
+\stoptyping
+
+or:
+
+\starttyping
+\def\getmatrix[#1]%
+  {\getparameters[@@matrix][sx=1,sy=1,rx=1,ry=1,#1]%
+   \domatrix
+     sx \@@matrixsx
+     sy \@@matrixsy
+     rx \@@matrixrx
+     ry \@@matrixry
+   \relax}
+\stoptyping
+
+In the second variant (with keywords) can be a scanner like we defined before:
+
+\starttyping
+\def\domatrix#1#2#3#4%
+  {\directlua{getmatrix()}}
+\stoptyping
+
+but also:
+
+\starttyping
+\def\domatrix#1#2#3#4%
+  {\directlua{getmatrix(#1,#2,#3,#4)}}
+\stoptyping
+
+given:
+
+\starttyping
+function getmatrix(sx,sy,rx,ry)
+    -- action using sx etc --
+end
+\stoptyping
+
+or maybe nicer:
+
+\starttyping
+\def\domatrix#1#2#3#4%
+  {\directlua{domatrix{
+     sx = #1,
+     sy = #2,
+     rx = #3,
+     ry = #4
+   }}}
+\stoptyping
+
+assuming:
+
+\starttyping
+function getmatrix(values)
+    -- action using values.sx etc --
+end
+\stoptyping
+
+If you go for speed the scanner variant without keywords is the most efficient
+one. For readability the scanner variant with keywords or the last shown example
+where a table is passed is better. For flexibility the table variant is best as
+it makes no assumptions about the scanner \emdash\ the token scanner can quit on
+unknown keys, unless that is intercepted of course. But as mentioned before, even
+the advantage of the fast one should not be overestimated. When you trace usage
+it can be that the (in this case matrix) macro is called only a few thousand
+times and that doesn't really add up. Of course many different sped-up calls can
+make a difference but then one really needs to optimize consistently the whole
+code base and that can conflict with readability. The token library presents us
+with a nice chicken||egg problem but nevertheless is fun to play with.
+
+\stopsection
+
+\startsection[title=Assigning meanings]
+
+The token library also provides a way to create tokens and access properties but
+that interface can change with upcoming versions when the old library is replaced
+by the new one and the input handling is cleaned up. One experimental function is
+worth mentioning:
+
+\starttyping
+token.set_macro("foo","the meaning of bar")
+\stoptyping
+
+This will turn the given string into tokens that get assigned to \type {\foo}.
+Here are some alternative calls:
+
+\starttabulate
+\NC \type {set_macro("foo")}                    \NC \type { \def \foo {}}        \NC \NR
+\NC \type {set_macro("foo","meaning")}          \NC \type { \def \foo {meaning}} \NC \NR
+\NC \type {set_macro("foo","meaning","global")} \NC \type {\gdef \foo {meaning}} \NC \NR
+\stoptabulate
+
+The conversion to tokens happens under the current catcode regime. You can
+enforce a different regime by passing a number of an allocated catcode table as
+the first argument, as with \type {tex.print}. As we mentioned performance
+before: setting at the \LUA\ end like this:
+
+\starttyping
+token.set_macro("foo","meaning")
+\stoptyping
+
+is about two times as fast as:
+
+\starttyping
+tex.sprint("\\def\\foo{meaning}")
+\stoptyping
+
+or (with slightly more overhead) in \CONTEXT\ terms:
+
+\starttyping
+context("\\def\\foo{meaning}")
+\stoptyping
+
+The next variant is actually slower (even when we alias \type {setvalue}):
+
+\starttyping
+context.setvalue("foo","meaning")
+\stoptyping
+
+but although 0.4 versus 0.8 seconds looks like a lot on a \TEX\ run I need a
+million calls to see such a difference, and a million macro definitions during a
+run is a lot. The different assignments involved in, for instance, 3000 entries
+in a bibliography (with an average of 5 assignments per entry) can hardly be
+measured as we're talking about milliseconds. So again, it's mostly a matter of
+convenience when using this function, not a necessity.
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+For sure we will see usage of the new scanner code in \CONTEXT, but to what
+extent remains to be seen. The performance gain is not impressive enough to
+justify many changes to the code but as the low|-|level interfacing can sometimes
+become a bit cleaner it will be used in specific places, even if we sacrifice
+some speed (which then probably will be compensated for by a little gain
+elsewhere).
+
+The scanners will probably never be used by users directly simply because there
+are no such low level interfaces in \CONTEXT\ and because manipulating input is
+easier in \LUA. Even deep down in the internals of \CONTEXT\ we will use wrappers
+and additional helpers around the scanner code. Of course there is the fun-factor
+and playing with these scanners is fun indeed. The macro setters have as their
+main benefit that using them can be nicer in the \LUA\ source, and of course
+setting a macro this way is also conceptually cleaner (just like we can set
+registers).
+
+Of course there are some challenges left, like determining if we are scanning
+input of already converted tokens (for instance in a macro body or token\-list
+expansion). Once we can properly feed back tokens we can also look ahead like
+\type {\futurelet} does. But for that to happen we will first clean up the
+\LUATEX\ input scanner code and error handler.

+Normally you will take the binaries from the \CONTEXT\ garden but if you ever want
+to compile yourself, it's not that hard to do. For \LINUX\ you need to install the
+compilers:
+
+\starttyping
+apt-get install gcc
+apt-get install g++
+\stoptyping
+
+Then you need to make sure you have a copy of the \LUATEX\ sources (you need to use
+your own paths):
+
+\starttyping
+cd /data
+svn checkout https://foundry.supelec.fr/svn/luatex/trunk luatex-trunk
+\stoptyping
+
+or update with:
+
+\starttyping
+cd /data
+svn update luatex-trunk
+\stoptyping
+
+and then export with:
+
+\starttyping
+cd /data
+svn export --force /data/luatex-trunk /data/luatex-trunk-export
+\stoptyping
+
+We go to the export directory and compile \LUATEX:
+
+\starttyping
+cd /data/luatex-trunk-export
+./build.sh --jit
+\stoptyping
+
+The binaries are already stripped (i.e.\ symbols get removed) which makes them
+much smaller.
+
+% strip -s /data/luatex-trunk-export/build/texk/web2c/luatex
+% strip -s /data/luatex-trunk-export/build/texk/web2c/luajittex

+cp data/luatex/luatex-trunk-export/build/texk/web2c/luajittex \
+    /data/context/tex/texmf-linux-64/bin
+\stoptyping
+
+The native windows binaries are kept very up|-|to|-|date but you can cross compile
+your own if needed. You need to make sure that the cross compiler is installed.
+
+\starttyping
+apt-get install gcc-mingw-w64-x86-64
+apt-get install g++-mingw-w64-x86-64
+apt-get install binutils-mingw-w64
+\stoptyping
+
+Given that you have exported the sources you can now run:
+
+\starttyping
+./build.sh --jit --mingw64
+\stoptyping
+
+Of course we assume a recent \LINUX\ installation here but on \WINDOWS\ you can
+the \quote {\LINUX\ subsystem for \WINDOWS} too. The files can be found in a dedicated
+build directory:
+
+% strip -s /data/luatex-trunk-export/build-windows64/texk/web2c/luatex.exe
+% strip -s /data/luatex-trunk-export/build-windows64/texk/web2c/luajittex.exe

+cp data/luatex/luatex-trunk-export/build-windows64/texk/web2c/luajittex.exe \
+    /data/context/tex/tex-context/tex/texmf-linux-64/bin
+\stoptyping
+
+You need to wipe out old traces of binaries, because these can confuse the \type {mtxrun}
+stub that checks for them, so we do:
+
+\starttyping
+rm /data/context/tex/tex-context/tex/texmf-win64/bin/luajittex.dll
+rm /data/context/tex/tex-context/tex/texmf-win64/bin/luatex.dll
+\stoptyping
+
+The libraries are compiled in a similar way. This time we get the sources from another
+repository:
+
+\starttyping
+cd /data
+svn checkout https://foundry.supelec.fr/svn/swiglib/trunk swiglib-trunk
+\stoptyping
+
+or update with:
+
+\starttyping
+cd /data
+svn update swiglib-trunk
+\stoptyping
+
+and then export with:
+
+\starttyping
+cd /data
+svn export --force /data/swiglib-trunk /data/swiglib-trunk-export
+\stoptyping
+
+This time you need to be quite explicit with respect to the libraries you want to
+compile :
+
+\starttyping
+cd /data/swiglib-trunk-export
+./build.sh --library=helpers --version=1.0.3
+\stoptyping
+
+You can save yourself some work with:
+
+\starttyping
+mtxrun --script --svnroot=/data/swiglib-trunk-export --make
+\stoptyping
+
+which will create a shell script \type {swiglib-make.sh} with commands that make
+all available libraries. After running that script you can update your tree
+with:
+
+\starttyping
+mtxrun --script --svnroot=/data/swiglib-trunk-export --update
+\stoptyping
+
+For \WINDOWS\ a similar route is followed but first you need to make sure that
+your binaries are able to deal with shared libraries:
+
+\starttyping
+./build-shared.sh --jit --mingw64 --shared
+\stoptyping
+
+Compiling is done as with \LINUX\ but you need to provide the \type {--mingw64}
+flag. Copying is done with:
+
+\starttyping
+cp /data/luatex/luatex-trunk-export/build-windows64-shared\
+    /texk/web2c/.libs/luatex.exe /data/context/tex/texmf-win64/bin
+cp /data/luatex/luatex-trunk-export/build-windows64-shared\
+    /texk/web2c/.libs/luajittex.exe /data/context/tex/texmf-win64/bin

+cp /data/luatex/luatex-trunk-export/build-windows64-shared\
+    /libs/luajit/.libs/texluajit*dll /data/context/tex/texmf-win64/bin
+cp /data/luatex/luatex-trunk-export/build-windows64-shared\
+    /texk/kpathsea/.libs/libkpathsea*dll /data/context/tex/texmf-win64/bin
+
+rm /data/context/tex/texmf-win64/bin/luajittex.dll
+rm /data/context/tex/texmf-win64/bin/luatex.dll

+
+If you're recompiling \type {--make} can save you some time. If your machine can

+The \CSS\ approach to filtering is a bit different from the path based one and is
+supported too. In fact, you can combine both methods. Depending on what you
+select, the \CSS\ one can be a little bit faster too. It has the advantage that
+one can select more in one go but at the same time looks a bit less attractive.
+This method was added just to show that it can be done but might be useful too. A
+selector is gogen between curly braces (after all \CSS\ uses them and they have no

+The next pages show some examples. For that we use the demo file:
+
+\typebuffer[selector-001]
+
+The class and id selectors often only make sense in \HTML\ like documents but they
+are supported nevertheless. They are after all just shortcuts for filtering by
+attribute. The class filtering is special in the sense that it checks for a class
+in a list of classes given in an attribute.
+
+\showCSSdemo{selector-001}{{.one}}
+\showCSSdemo{selector-001}{{.one, .two}}
+\showCSSdemo{selector-001}{{.one, .two, \letterhash first}}
+
+Attributes can be filtered by presence, value, partial value and such. Quotes are
+optional but we advice to use them.
+
+\showCSSdemo{selector-001}{{[foo], [bar=foo]}}
+\showCSSdemo{selector-001}{{[bar\lettertilde=foo]}}
+\showCSSdemo{selector-001}{{[bar\letterhat="foo"]}}
+\showCSSdemo{selector-001}{{[whatever\lettertilde="five"]}}
+
+You can of course combine the methods as in:
+
+\showCSSdemo{selector-001}{{g f .one, g f .three}}
+\showCSSdemo{selector-001}{{g > f .one, g > f .three}}
+\showCSSdemo{selector-001}{{d + e}}
+\showCSSdemo{selector-001}{{d ~ e}}
+\showCSSdemo{selector-001}{{d ~ e, g f .one, g f .three}}
+
+You can also negate the result by using \type {:not} on a simple expression:
+
+\showCSSdemo{selector-001}{{:not([whatever\lettertilde="five"])}}
+\showCSSdemo{selector-001}{{:not(d)}}
+
+The child and match selectors are also supported:
+
+\showCSSdemo{selector-001}{{a:nth-child(3)}}
+\showCSSdemo{selector-001}{{a:nth-last-child(3)}}
+\showCSSdemo{selector-001}{{g:nth-of-type(3)}}
+\showCSSdemo{selector-001}{{g:nth-last-of-type(3)}}
+\showCSSdemo{selector-001}{{a:first-child}}
+\showCSSdemo{selector-001}{{a:last-child}}
+\showCSSdemo{selector-001}{{e:first-of-type}}
+\showCSSdemo{selector-001}{{gg d:only-of-type}}
+
+Instead of numbers you can also give the \type {an} and \type {an+b} formulas
+as well as the \type {odd} and \type {even} keywords:
+
+\showCSSdemo{selector-001}{{a:nth-child(even)}}
+\showCSSdemo{selector-001}{{a:nth-child(odd)}}
+\showCSSdemo{selector-001}{{a:nth-child(3n+1)}}
+\showCSSdemo{selector-001}{{a:nth-child(2n+3)}}
+
+There are a few special cases:
+
+\showCSSdemo{selector-001}{{g:empty}}
+\showCSSdemo{selector-001}{{g:root}}
+\showCSSdemo{selector-001}{{*}}
+
+Combining the \CSS\ methods with the regular ones is possible:
+
+\showCSSdemo{selector-001}{{g gg f .one}}
+\showCSSdemo{selector-001}{g/gg/f[@class='one']}
+\showCSSdemo{selector-001}{g/{gg f .one}}

+
+\showCSSdemo{selector-002}{{document title .one, document title .three}}
+
+\showCSSdemo{selector-002}{/document/title[(@class='one') or (@class='three')]}

+</document>
+\stopbuffer

+\typebuffer[selector-003]

+\xmlloadbuffer{selector-003}{selector-003}

+The next filter in easier with the \CSS\ selector methods because these accumulate
+independent (simple) expressions:
+
+\showCSSdemo{selector-003}{{document title .one + subtitle, document title .two + subtitle}}
+
+Watch how we get an output in the document order. Because we render a sequential document
+a combined filter will trigger a sorting pass.

+
+\starttyping
+\xmldoif {#1} {/crap/crapa/crapb/crapc/crapd/crape} {

+    \xmlfirst{#1}{/crap/crapa/crapb/crapc/crapd/crape}
+}
+\stoptyping
+
+This means that the path is resolved twice but that can be avoided as
+follows:
+
+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlfirst{#1}{last-match::}
+}
+\stoptyping
+

+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlfirst{#1}{last-match::}
+    \xmllast{#1}{last-match::}
+}
+\stoptyping
+
+Because the first one can have done some lookup the last match can be replaced
+and the second call will give unexpected results. You can overcome this with:
+
+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlpushmatch
+    \xmlfirst{#1}{last-match::}

+One might wonder how a \TEX\ macro package would look like when backslashes,
+dollars and percent signs would have no special meaning. In fact, it would be
+rather useless as interpreting commands are triggered by such characters. Any
+formatting or coding system needs such characters. Take \XML: angle brackets and
+ampersands are really special. So, no matter what system we use, we do have to
+deal with the (common) case where these characters need to be sees as they are.
+Normally escaping is the solution.
+
+The \CONTEXT\ interface for \XML\ suffers from this as well. You really don't
+want to know how many tricks are used for dealing with special characters and
+entities: there are several ways these travel through the system and it is
+possible to adapt and cheat. Especially roundtripped data (via tuc file) puts

--- todo: we need to clean up lists (of previous pages)
+-- This is a bit messy module but backgrounds are messy anyway. Especially when we want to
+-- follow shapes. This will always be work in progress as it also depends on new features
+-- in context.
+--
+-- Alas, shapes and inline didn't work as expected end of 2016 so I had to pick up this
+-- thread again. But with regular excursions to listening to Brad Mehldau's Mehliana I
+-- could keep myself motivated. Some old stuff has been removed, some suboptimal code has
+-- been replaced. Background code is still not perfect, but some day ... the details manual
+-- will discuss this issue.

--- tflush needs checking ... sort of weird that it's not a table
--- __flushlines is an experiment and rather ugly so it will go away

+%D We define color groups having equal gray scale values by either reducing 
+%D their rgb values to darken them or by adding equal amounts of $r=g=b$ to 
+%D lighten them.

+There is not really a long term roadmap for development. One reason is that there is already
+a lot available. When we started with \LUATEX, the \CONTEXT\ code was mostly rewritten,
+and that process is more of less finished. Of course there is always work left.
+
+This file is not a complete overview of our plans but users can at least get an
+idea of what we're working on and what is coming. Feel free to submit
+suggestions.

+-- This version is different from previous in the sense that we no longer store
+-- contours but keep points and contours (endpoints) separate for a while
+-- because later on we need to apply deltas and that is easier on a list of
+-- points.
+
+-- The code is a bit messy. I looked at the ff code but it's messy too. It has
+-- to do with the fact that we need to look at points on the curve and control
+-- points in between. This also means that we start at point 2 and have to look
+-- at point 1 when we're at the end. We still use a ps like storage with the
+-- operator last in an entry. It's typical code that evolves stepwise till a
+-- point of no comprehension.
+
+-- For deltas we need a rather complex loop over points that can have holes and
+-- be less than nofpoints and even can have duplicates and also the x and y value
+-- lists can be shorter than etc. I need fonts in order to complete this simply

+%D After a decade of playing with these things in \LUATEX|/|\MKIV\ it's time to
+%D finish the way we deal with discretionaries. Apart from the fact that they play a
+%D role in hyphenation they also need to be dealt with in fonts. Flattening, cleanup
+%D and such are now more or less default in \CONTEXT\ so we can simplify some of the
+%D code. We also use the new penalty mechanism.

+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D See source code for comments. I wrote this a follow up on a presentation by
+%D Kai Eigner, left it for a while, and sort of finalized it the last quarter of
+%D 2016. As I don't use this module, apart from maybe testing something, it is
+%D not guaranteed to work. Also, plugins can interfere with other functionality
+%D in \CONTEXT\ so don't expect too much support. The two modules mentioned
+%D below should work in the generic loader too. It's anyhow an illustration of
+%D how \type {ffi} can work be used in a practical application.

+%D Some inline math tweak.
 
-%D [The examples below are in english and don't process in the
-%D  documentation style, which will be english some day.]
-%D
-%D Normally a formula is centered, but in case you want to
-%D align it left or right, you can set up formulas to behave
-%D that way. Normally a formula will adapt is left indentation
-%D to the environment:
-%D
-%D \startbuffer
-%D \fakewords{20}{40}\epar
-%D \startitemize
-%D \item \fakewords{20}{40}\epar
-%D       \placeformula \startformula \fakeformula \stopformula
-%D \item \fakewords{20}{40}\epar
-%D \stopitemize
-%D \fakewords{20}{40}\epar
-%D \stopbuffer
-%D
-%D % \getbuffer
-%D
-%D In the next examples we explicitly align formulas to the
-%D left (\type {\raggedleft}), center and right (\type
-%D {\raggedright}):
-%D
-%D \startbuffer
-%D \setupformulas[align=left]
-%D \startformula\fakeformula\stopformula
-%D \setupformulas[align=middle]
-%D \startformula\fakeformula\stopformula
-%D \setupformulas[align=right]
-%D \startformula\fakeformula\stopformula
-%D \stopbuffer
-%D
-%D \typebuffer
-%D
-%D Or in print:
-%D
-%D % {\getbuffer}
-%D
-%D With formula numbers these formulas look as follows:
-%D
-%D \startbuffer
-%D \setupformulas[align=left]
-%D \placeformula \startformula\fakeformula\stopformula
-%D \setupformulas[align=middle]
-%D \placeformula \startformula\fakeformula\stopformula
-%D \setupformulas[align=right]
-%D \placeformula \startformula\fakeformula\stopformula
-%D \stopbuffer
-%D
-%D % {\getbuffer}
-%D
-%D This was keyed in as:
-%D
-%D \typebuffer
-%D
-%D When tracing is turned on (\type {\tracemathtrue}) you can
-%D visualize the bounding box of the formula,
-%D
-%D % {\tracemathtrue\getbuffer}
-%D
-%D As you can see, the dimensions are the natural ones, but if
-%D needed you can force a normalized line:
-%D
-%D \startbuffer
-%D \setupformulas[strut=yes]
-%D \placeformula \startformula \fakeformula \stopformula
-%D \stopbuffer
-%D
-%D \typebuffer
-%D
-%D This time we get a more spacy result.
-%D
-%D % {\tracemathtrue\getbuffer}
-%D
-%D We will now show a couple of more settings and combinations
-%D of settings. In centered formulas, the number takes no space
-%D
-%D \startbuffer
-%D \setupformulas[align=middle]
-%D \startformula \fakeformula \stopformula
-%D \placeformula \startformula \fakeformula \stopformula
-%D \stopbuffer
-%D
-%D \typebuffer % {\tracemathtrue\getbuffer}
-%D
-%D You can influence the placement of the whole box with the
-%D parameters \type {leftmargin} and \type {rightmargin}.
-%D
-%D \startbuffer
-%D \setupformulas[align=right,leftmargin=3em]
-%D \startformula \fakeformula \stopformula
-%D \placeformula \startformula \fakeformula \stopformula
-%D
-%D \setupformulas[align=left,rightmargin=1em]
-%D \startformula \fakeformula \stopformula
-%D \placeformula \startformula \fakeformula \stopformula
-%D \stopbuffer
-%D
-%D \typebuffer % {\tracemathtrue\getbuffer}
-%D
-%D You can also inherit the margin from the environment.
-%D
-%D \startbuffer
-%D \setupformulas[align=right,margin=standard]
-%D \startformula \fakeformula \stopformula
-%D \placeformula \startformula \fakeformula \stopformula
-%D \stopbuffer
-%D
-%D \typebuffer % {\tracemathtrue\getbuffer}
-%D
-%D The distance between the formula and the number is only
-%D applied when the formula is left or right aligned.
-%D
-%D \startbuffer
-%D \setupformulas[align=left,distance=2em]
-%D \startformula \fakeformula \stopformula
-%D \placeformula \startformula \fakeformula \stopformula

+%I Invuloefeningen kunnen worden vormgegeven met het
+%I de commando's:
+%I
+%I   \definieerinvulwoord[trefwoord]{woord,woord}
+%I   \invulwoord[trefwoord]
+%I   \invulwoord{woord,woord,...}
+%I
+%I Daarbij kan het een en ander worden ingesteld met
+%I
+%I   \stelinvullenin[status=,nummer=,links=,rechts=,letter=]
+%P
+%I Er zijn drie manieren om woorden in te vullen. De meest
+%I eenvoudige is die waarbij de in te vullen woorden in de
+%I tekst staan.
+%I
+%I   bla bla \invulwoord{een,alfa} bla bla bla bla bla bla
+%I   bla bla bla bla bla bla bla bla \invulwoord{twee,beta}.
+%I
+%I De gezette tekst hangt af van de instellingen:
+%I
+%I   [status=leeg]             ________
+%I   [status=vol,nummer=1]     'een' respectievelijk 'twee'
+%I   [status=vol,nummer=2]     'alfa' respectievelijk 'beta'
+%I
+%I Het nummer heeft dus betrekking op het volgnummer in de
+%I opgegeven reeks.
+%P
+%I Bij de tweede manier worden eerste de alternatieven
+%I gedefinieerd:
+%I
+%I   \definieerinvulwoord{een,alfa}
+%I   \definieerinvulwoord{twee,beta}
+%I
+%I die vervolgens worden opgeroepen:
+%I
+%I   bla \invulwoord[+] bla bla bla bla bla bla bla bla bla
+%I   bla bla bla bla bla bla bla bla bla bla \invulwoord[+].
+%I
+%I De mogelijke instellingen komen overeen met die van de
+%I eerste manier.
+%P
+%I De derde manier is een variant op de tweede. Bij grote
+%I teksten kan men het overzicht kwijtraken. Het is daarom
+%I mogelijk 'logische' namen toe te kennen aan woorden.
+%I
+%I   \definieerinvulwoord[a]{een,alfa}
+%I   \definieerinvulwoord[b]{twee,beta}
+%I
+%I die vervolgens worden opgeroepen:
+%I
+%I   bla \invulwoord[a] bla bla bla bla bla bla bla bla bla
+%I   bla bla bla bla bla bla bla bla bla bla \invulwoord[b].
+%I
+%I Dit maakt het bovendien mogelijk woorden meerdere malen
+%I (in een willekeurige volgorde op te roepen:
+%I
+%I   bla \invulwoord[a] bla \invulwoord[b] bla bla bla bla
+%I   bla bla bla bla \invulwoord[b] bla bla \invulwoord[a].
+%P
+%I Bij [status=leeg] wordt een streep gezet die in breedte
+%I overeenkomt met het woord dat er eigenlijk hoort te
+%I staan. De ingevulde tekst komt visueel daardoor overeen
+%I met de in te vullen tekst, wat vergelijken vereenvoudigd.
+%I
+%I Met [status=reset] worden enkele tellers weer op 0 gezet.
+%I Dit kan nodig zijn als meerdere invuloefeningen in een
+%I tekst worden gezet.
+%I
+%I Als \versie[voorlopig] is ingesteld, worden bij invullers
+%I zonder logische namen tussen haakjes de volgnummers
+%I getoond.

+% This style is used for producing explanationary documents.
+% Don't misuse it for other purposes, since it may confuse

+%
+% The layout setup is such that one has several text areas

+
+We've chosen a layout which is more functional than
+beautiful. This layout provides several text areas: headers

+The surrounding (gray) makes the main page (which is

+The documents produced at \PRAGMA\ are called {\bf This

+lead to clashes with files distributed by \PRAGMA.

+%D For screen reading, a Lucida Bright font looks nice. We use

+%D
+%D Screen presentations without color just look dull, so we
+%D enable color support. We define ourselves a yellowish
+%D backgroundcolor and a not too dark blue interactioncolor.
+
+\setupcolors
+  [state=start]

+
+%D \macros
+%D   {setuppapersize,setuplayout,setupinteractionscreen}
+%D
+%D
+%D We use a nice large screen, and dedicate the right edge and
+%D bottom part to navigational tools. We automatically set
+%D the width and height of the page and start up full screen.
+

+%D
+%D We set the pagecolor to yellow except the part of the screen

+%D offset to 3pt the text will not touch the yellow parts. We
+%D do not set the depth.

+%D
+%D We did not enable interactive text support yet, so let's do
+%D that now. We force page reference to circumvent problems
+%D with named destinations in buggy viewers.

+
+%D \macros
+%D   {setupinteractionmenu,startinteractionmenu}
+%D
+%D At the bottom of the screen we show two navigational bars.
+%D At the left we show the subpage bar, at the right we use a
+%D non default backward|/|forward bar.

+%D \macros
+%D   {interactionbar}
+%D
+%D The left bar gets a white border (on the yellow background).
+%D Because we don't want to typeset an empty frame when no
+%D subpage bar is shown, we check for the number of subpages.
+
+\def\InteractionBar%
+  {\ifnum\nofsubpages>1
+     \framed
+       [framecolor=white,rulethickness=1pt,

+   \fi}
+
+%D \macros
+%D   {setupinteractionbar, interactionbuttons}
+%D
+%D The right hand buttons enable us to jump backward and forward,
+%D as well as to the previous and next jump. We also enable to
+%D close the presentation.
+
+\setupinteractionbar
+  [framecolor=white,rulethickness=1pt,

+      lastpage,
+      CloseDocument]}
+
+%D \macros
+%D  {StartTitlePage, TitlePage}
+%D
+%D The titlepage is rather simple and can be typeset in two
+%D ways:
+%D
+%D \starttyping
+%D \StartTitlePage
+%D text \\ text \\ text
+%D \StopTitlepage
+%D \stoptyping
+%D
+%D or more straightforward:
+%D
+%D \starttyping
+%D \TitlePage{text\\text\\text}
+%D \stoptyping
+%D
+%D The first alternative can be used for more complicated
+%D title pages.
+
+\def\StartTitlePage%
+  {\startstandardmakeup
+   \bfd\setupinterlinespace
+   \setupalign[middle]
+   \vfil
+   \let\\=\vfil}

+
+\def\TitlePage#1%
+  {\StartTitlePage#1\StopTitlePage}
+
+%D \macros
+%D   {TitlePage, Topics, Topic, Subject}
+%D
+%D A presentation after loading this module looks like:
+%D
+%D \starttyping
+%D \TitlePage {About Whatever\\Topics}
+%D
+%D \Topics {Todays Talk}
+%D
+%D \Topic {Some topic}
+%D
+%D \Subject {Alfa}
+%D
+%D .....
+%D
+%D \Subject {Beta}
+%D
+%D .....
+%D \stoptyping
+
+%D \macros
+%D   {definehead}
+%D
+%D The commands \type{\Topic} and \type{\Subject} are defined
+%D as copies of head. We use \type{\Nopic} for internal
+%D purposes.
+
+\definehead [Topic]   [chapter]
+\definehead [Subject] [section]
+
+\definehead [Nopic]   [title]
+
+%D \macros
+%D   {setuphead}
+%D
+%D Because chapters and sections do not make sense in
+%D presentations, we use our own command for typesetting the
+%D titles. Sectionnumbers are of course hidden from viewing.
+%D Each topic is followed by a list of subjects that belong
+%D to the topic.
+
+\setuphead
+  [Topic, Nopic, Subject]
+  [command=\HeadLine,
+   page=yes,
+   style=\tfb,
+   after=\blank,
+   sectionnumber=no]
+
+\setuphead
+  [Topic]
+  [after=\PlaceSubjectList]
+
+\setuphead
+  [Subject]
+  [continue=no]
+
+%D \macros
+%D   {framed, midalined}
+%D
+%D The command used to typeset the head lines is rather simple.
+%D We just center the framed title. The frame macro optimizes
+%D the alignment and at the same time enables us to typeset a
+%D nice colored rule.
+
+\def\HeadLine#1#2%
+  {\midaligned
+     {\framed
+        [framecolor=BackgroundColor,rulethickness=1pt,
+         width=.8\hsize,align=middle,strut=no]
+        {#2}}}
+
+%D \macros
+%D   {setuplist}
+%D
+%D The subject list is automatically placed. We center each
+%D subject line by using one of the default alternatives (g). We
+%D could have said:
+%D
+%D \starttyping
+%D \setuplist
+%D   [Subject]
+%D   [alternative=none,
+%D    command=\SubjectListLine,
+%D    interaction=all]
+%D
+%D \def\SubjectListLine#1#2#3%
+%D   {\midaligned{#2}}
+%D \stoptyping
+%D
+%D But why should we complicate things when we can use
+%D alternative~\type{g}. The test is only needed if one
+%D does not automatically goes a new page with each subject.
+
+\def\PlaceSubjectList%
+  {\blank
+   \determinelistcharacteristics[Subject]
+ % \ifnum\utilitylistlength>0 \placelist[Subject] \fi}
+   \doifmode{*list}{\placelist[Subject]}}
+
+\setuplist
+  [Subject, Topic]
+  [alternative=g,
+   interaction=all,
+   before=,
+   after=]
+
+% %D \macros
+% %D   {setuptexttexts}
+% %D
+% %D The topics will be listed in the right edge, using:
+%
+% \setuptexttexts
+%   [edge]
+%   [][\TopicList]
+
+%D \macros
+%D   {setuplist, placelist,startinteractionmenu}
+%D
+%D The actual topic list is typeset using a \type{\vbox}. We
+%D have to specify \type{criteriumcriterium=all} because otherwise no
+%D list will be typeset. (By default lists are typeset
+%D locally.)
+
+\startinteractionmenu[right]
+  \placelist
+    [Topic]
+    [alternative=f, % command, % none,
+     maxwidth=\hsize,
+     width=\hsize,

+\stopinteractionmenu
+
+\def\Topics#1% temporary hack
+  {\Nopic{#1}
+   \placelist[Topic][criterium=all]}
+
+\def\Subjects%
+  {}
+
+%D \macros
+%D   {setuptexttexts, button}
+%D
+%D During a presentation, we want to use the cursor to point to
+%D parts of the text. Furthermore we want to be able to jump to
+%D the next page, without the need to move the cursor on buttons.
+%D Therefore we make the text part of the screen into an
+%D invisible button.
+
+\setuptexttexts
+  [\GotoNextPage][]
+
+\def\GotoNextPage
+  {\button[width=\hsize,height=\vsize,frame=off]{}[nextpage]}
+
+%D \macros
+%D   {setupsubpagenumber}
+%D
+%D The left bottom navigation bar shows the subpages, which will
+%D be counted by text. One can change this in the preentation
+%D itself by saying \type {[way=byTopic]}.
+
+\setupsubpagenumber

+%D \macros
+%D   {setupcolors,definecolor}
+%D
+%D I started using dark blue for the navigational elements. In
+%D that context, dark red is a logical choice for the contrast
+%D color. While playing around with the navigational elements
+%D I decided to use the not so dominant color yellow for the
+%D status bar.
+%D
+%D A few days before I wrote this style, the recent acquisition
+%D of Mondriaans last painting by the Dutch governement was a
+%D hot topic in the dutch news scenary. Therefore I decided to
+%D replace the rather dull title page by something more
+%D colorful, in mondriaan colors, but far more random than any
+%D of his paintings. For consistence we remap the already
+%D defined primary colors.

+%D   {setupbackgrounds}
+%D
+%D Both the page and the text area have a gray background.

+\setupsubpagenumber
+  [state=start,
+   way=bytext]
+
+%D \macros
+%D   {setupinteractionmenu}
+%D
+%D There is only one interaction menu, located in the right
+%D edge of the screen. Both offsets enlarge the edge by the
+%D same amount as the text background offset.

+%D
+%D The menu itself is not that spectacular. We use the

+%D \type {\interactioncolor} expands into either the
+%D interaction color or the contrast color, the latter only
+%D when no jump is possible.

+%D I made this style when I had to give a presentation on

+%D A couple of years later, in 2001 this style was documented

+%D building on top of overlays into the now available layer
+%D positioning. So, this styles demonstrates quite some
+%D tricks.

+\defineoverlay [skippage]     [\overlaybutton{page(+2)}]

+%D Layers are normally used to position multiple content on
+%D a specific overlay. Here we will use them to position
+%D only and since the samples and text will swap place, we
+%D will use quite a few layers.
+
+\defineoverlay [text]   [\composedlayer{text}]
+\defineoverlay [sample] [\composedlayer{sample}]
+\defineoverlay [common] [\composedlayer{common}]
+
+%D There are three positions. When combined, the sample and
+%D text windows overlap, otherwise the lone window is
+%D centered. We could have used one layer and reversed the
+%D order by setting the \type {direction} parameter, but
+%D this approach is more readable.
+
+\definelayer
+  [text]
+  [x=\makeupwidth,y=\makeupheight,location=lt,
+   hoffset=-\FrameSkip,voffset=-\FrameSkip]

+
+\definelayer
+  [common]
+  [x=.5\makeupwidth,y=.5\makeupheight,location=c]
+
+%D The topic is put in the lower right corner of the text
+%D window.
+
+\defineoverlay [topic] [\composedlayer{topic}]
+
+\definelayer
+  [topic]
+  [x=\FrameWidth,y=\FrameHeight,location=lt,
+   hoffset=-\FrameOffset,voffset=-\FrameSkip]
+
+%D The topic is put in a framed box. That way we can make
+%D sure that it gets a background, which looks better when
+%D it covers something else. Otherwise we could have stuct
+%D to:
+%D
+%D \starttyping
+%D \def\Topic#1%
+%D   {\setlayer[topic]{\color[PageColor]{\bfb\setstrut#1}}}
+%D \stoptyping
+%D
+%D But, we go for the nice alternative:
+
+\def\Topic#1%
+  {\doifsomething{#1}
+     {\setlayer [topic]
+        {\bfb\setstrut
+         \inframed
+           [frame=off,foregroundcolor=PageColor,offset=0pt,
+            background=color,backgroundcolor=TextColor]
+           {#1}}}}
+
+%D The sample as well as the explanation will be collected in
+%D a buffer. That way we can reuse the content. We could
+%D have used a box instead, but can we be sure that the content
+%D is not adapting itself? So, buffers we use.
+
+\resetbuffer[sample]
+\resetbuffer[text]
+
+%D Both the sample and explanation are kind of windowed.
+
+\defineframedtext
+  [SampleText]
+  [width=\FrameWidth,height=\FrameHeight,offset=\FrameOffset,
+   frame=off,align=normal,strut=no,before=,after=,
+   background={background,nextpage}]
+
+%D We safe some keying in by combining things in one macro.
+
+\def\DoSampleText#1#2#3% kind layer overlays
+  {\setupframedtexts[SampleText][background={background,#3}]
+   \setlayer[#2]
+     {\startSampleText[none]
+        \setups[#1]
+        \getbuffer[#1]
+      \stopSampleText}}
+
+\def\StartSample{\dostartbuffer[sample][StartSample][StopSample]}
+\def\StartText  {\dostartbuffer[text]  [StartText]  [StopText]}
+
+%D The following definitions apply at the outer level.
+
+\def\StopSample
+  {\startstandardmakeup
+     \DoSampleText{sample}{common}{nextpage}
+   \stopstandardmakeup
+   \resetbuffer[sample]}

+   \stopstandardmakeup
+   \resetbuffer[text]}
+
+\setupbackgrounds[page][background={color,nextpage}]
+\setupbackgrounds[text][background=common]
+
+%D When we combine sample and text, we get slightly
+%D different definitions. As you can see we generate two
+%D pages. Watch how we manipulate the order of the
+%D overlays and teh nature of the buttons. Here data
+%D abstraction really pays off.

+%D The topic goes to the top right corner of the screen which
+%D means that it is positioned left down to the reference
+%D point. Watch how we make data on this layer (here only

+%D We also provide a way to erase the topic.

+\def\StopSubText
+  {\startstandardmakeup

+%D The \type {\DoSampleText} command is adapted to support
+%D addition of subtexts (each subtext goes into its own
+%D buffer).

+%D In the process of making a couple of simple styles for
+%D \EUROTEX\ 99, I came to this one. The joke is in the
+%D pagenumber. This style can be used for short presentations
+%D with much text.

+\startmode[asintended] \setupbodyfont[lbr] \stopmode
+
+\setupbodyfont[14.4pt]

+%D Since we expect text, we can best be very tolerant.

+   footer=0pt,
+   topspace=1cm,
+   backspace=1cm]
+
+%D We only use two colors, named \type {One} and \type
+%D {Two}:
+
+\setupcolors
+  [state=start]
+
+\definecolor [One] [r=.6,g=.4,b=.4]
+\definecolor [Two] [r=.4,g=.6,b=.6]
+
+%D If you've looked at the demo file, you will have noticed
+%D that the background consists of four pieces: two filled
+%D rectangles and two half numbers. These are put on th epage
+%D using four overlays:
+
+\setupbackgrounds
+  [page]
+  [background={one,two,three,four}]
+
+%D When we code this in \TEX, we get the following
+%D definitions. As an alternative we coudl have used layers
+%D but I'm afraid that it would not have led to less code.
+
+\defineoverlay
+  [one]

+         [frame=off,background=color,backgroundcolor=One,
+          width=\overlaywidth,height=\overlayheight]
+         {}}}]
+
+%D We could have used the main backgroundcolor instead of
+%D overlay \type {one}.

+   \edef\overlaywidth{\the\scratchdimen}}
+
+%D A much cleaner implementation is the following. If you hate
+%D \METAPOST, you can run this style in the specified mode:
+
+\startnotmode[no-metapost]
+
+\setupbackgrounds
+  [page]
+  [background={number}]
+
+\defineoverlay[number][\useMPgraphic{number}]
+
+\startuseMPgraphic{number}
+  StartPage ;
+    path Vage ; picture Left, Right ;
+    x1 = x2 = xpart (llcorner Field[Text][RightEdge] shifted (-RightEdgeDistance/2,0)) ;
+    y1 = ypart llcorner Page ;
+    y2 = ypart ulcorner Page ;
+    Vage := llcorner Page -- z1 -- z2 -- ulcorner Page -- cycle ;
+    fill Page withcolor \MPcolor {One} ;
+    fill Vage withcolor \MPcolor {Two} ;
+    if PageNumber>0 :
+      defaultfont  := "\truefontname{RegularBold}" ;
+      Left := Right := thelabel("\folio",origin) ysized 3cm ;
+      clip Right to boundingbox Right shifted (bbwidth(Right)/2,0) ;
+      draw Left  shifted z1 shifted (0,2.25cm) withcolor \MPcolor {One} ;
+      draw Right shifted z1 shifted (0,2.25cm) withcolor \MPcolor {Two} ;
+    fi ;
+  StopPage ;
+\stopuseMPgraphic
+
+\stopnotmode
+
+%D We use the simple label typesetting present in \METAPOST\
+%D because digits are seldom kerned so real \TEX ing is not
+%D needed. As in the previous method, we let the graphics
+%D overlap so that we don't get white lines due to rounding
+%D problems in viewers.
+%D
+%D We put a  button behind the text (this overlay is calculated
+%D each page).
+
+\defineoverlay
+  [nextpage]
+  [\overlaybutton{nextpage}]
+
+\setupbackgrounds
+  [text]
+  [backgroundoffset=.5cm,
+   background=nextpage]
+
+%D We still have to turn on interaction mode.
+
+\setupinteraction
+  [state=start,
+   display=new,
+   menu=on]
+
+\setupinteraction
+  [color=,
+   contrastcolor=]
+
+%D Next we define structuring commands.
+
+\definehead[Topic]  [chapter] \setuphead[Topic]  [style=\bfc]
+\definehead[Subject][section] \setuphead[Subject][style=\bfa]
+
+\setuphead
+  [Topic,Subject]
+  [number=no,
+   after={\blank[big]}]
+
+%D Because we will provide a menu, we don't offer lists.
+
+\let\Topics  \gobbleoneargument
+\let\Subjects\relax
+
+%D The table of contents goes to the right edge.
+
+\startinteractionmenu[right]
+  \setupinteraction
+    [color=black,
+     contrastcolor=Two]
+  \placelist
+    [Topic]
+    [alternative=e,
+     frame=off,
+     criterium=all]
+  \vfill
+\stopinteractionmenu
+
+\setuplist
+  [Topic]
+  [width=\rightedgewidth,
+   maxwidth=\rightedgewidth,
+   style=\bfa]
+
+%D We safe some space:
+
+\setupwhitespace
+  [medium]
+
+\setupblank
+  [medium]
+
+%D In the titlepage, we still use the \TEX\ overlays,

+%D This is one of the styles I made for the presentation on
+%D the \NTS\ project at Euro\TeX\ 1998. You need balls to let
+%D \TEX\ typeset graphics, but this style demonstrates that it
+%D can be done.

+%D This style is made in the process or writing the \METAFUN\
+%D manual. It exploits a few tricks, like graphics calculated
+%D using positional information. It also uses the (at that
+%D moment) new menu list placement alternative. If you forget
+%D about the definition of the button shapes, which is
+%D complicated in any system, this style is not even that hard
+%D to follow. Watch how the left side of the buttons follow
+%D the right side of the text graphic.
+%D
+%D While playing bit with this style, the random alternative
+%D made me think of those organic building with non equal
+%D windows (we have a few in The Netherlands), so I decided to
+%D label this style as \type {pre-organic}.
+%D
+%D At the end of this file, there is a small test file, so
+%D when you process this file with \TEXEXEC\ and the options
+%D \type {--mode=demo} and \type {--pdf}, you will get a demo
+%D document.
+
+%D We use one of the standard screen \quote {paper} sizes, and
+%D map it onto the same size, so that we get a nicely cropped
+%D page.
+
+\setuppapersize
+  [S6][S6]
+
+%D Like in the \METAFUN\ manual, we use the Palatino as main
+%D bodyfont. This font is quite readable on even low
+%D resolution screens, although I admit that this style is
+%D developed using an $1400\times1050$ pixel LCD screen, so I
+%D may be biased.
+
+%\startmode[asintended] \setupbodyfont[ppl] \stopmode
+
+%D The layout specification sets up a text area and a right
+%D edge area where the menus will go. Watch the rather large
+%D edge distance. By setting the header and footer dimensions
+%D to zero, we automatically get rid of page body ornaments,
+%D like the pagenumber.
+

+   rightedgedistance=48pt,
+   header=0cm,
+   footer=0cm,
+   height=middle]
+
+%D We use a moderate, about a line height, interparagraph
+%D white space.
+
+\setupwhitespace
+  [big]
+
+%D Of course we use colors, since on computer displays they
+%D come for free.

+\definecolor [InteractionColor] [red]
+\definecolor [ContrastColor]    [gray]
+
+%D This is an interactive document, so we enable interaction.
+%D In this style, we disable the viewer's \quote {highlight a
+%D hyperlink when it's clicked on} feature. We will use a
+%D menu, so we enable menus. Later we will see the contract
+%D color |<|hyperlinks gets that color when we are already on
+%D the location|>| in action.
+
+\setupinteraction
+  [state=start,
+   click=off,
+   color=InteractionColor,
+   contrastcolor=ContrastColor,
+   menu=on]
+
+%D The menu itself is set up as follows. Because we will
+%D calculate menubuttons based on their position on the page,
+%D we have to keep track of the positions. Therefore, we set
+%D the \type {position} variable to \type {yes}.
+
+\setupinteractionmenu

+   position=yes,

+   bottomoffset=-.75cm,
+   color=gray,
+   contrastcolor=gray,
+   style=bold,
+   before=,
+   after=]
+
+%D The menu content is rather sober: a list of topics (later
+%D we will define the command that generates topic entries),
+%D and a close button.
+

+  \vfill
+  \but [CloseDocument] close \\
+\stopinteractionmenu
+
+%D We have now arived at the more interesting part of the style
+%D definition: the graphic that goes in the page background.
+%D Because this graphic will change, we define a usable
+%D \METAPOST\ graphic. Page backgrounds are recalculated each
+%D page, opposite to the other backgrounds that are calculated
+%D when a new background is defined, or when repetitive
+%D calculation is turned on.

+\StartItem the \OPENTYPE\ font reader is borrowed from \FONTFORGE\  \FlushStep \StopItem
+\StartItem once it was ready, we could look into such a font  \FlushStep \StopItem
+\StartItem it tooks while to figure out the format due to rather fuzzy specs  \FlushStep \StopItem
+\StartItem it took us even more time to find out that the loader was flawed  \FlushStep \StopItem
+\StartItem one reason was that fonts themselves may have bugs or be incomplete \FlushStep \StopItem
+\StartItem then we changed to \FONTFORGE\ version 2 \FlushStep \StopItem
+\StartItem this made the missing pieces surface in more complex feature handling \FlushStep \StopItem
+\StartItem while implementing features the new table format was cleaned up \FlushStep \StopItem

+%D Currently asymptote assumes \MKII\ but better is to only support \MKIV. A problem
+%D is that asymptote has this hard coded while for \CONTEXT\ it's better to stick to
+%D something simple:
+%D
+%D \starttyping
+%D \starttext
+%D
+%D \startasymptotepage
+%D     some label
+%D \stopasymptotepage
+%D
+%D \startasymptotepage
+%D     some label
+%D \stopasymptotepage
+%D
+%D \stoptext
+%D \stoptyping
+%D
+%D Which is then run with:
+%D
+%D \starttyping
+%D context --nonstopmode --purge somefile.tex
+%D \stoptyping
+%D
+%D For the moment add "settings.prc=true;" to a graphic that is meant to produce that
+%D format. See end of file for some examples.

+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D This style is used for producing explanationary documents. Don't misuse it for
+%D other purposes, since it may confuse users. Don't change the title either, since
+%D it provides a way to categorize documents. Numbers are disabled in instances
+%D produced outside PRAGMA ADE.
+%D
+%D The layout setup is such that one has several text areas available: headers and
+%D footers, margins and edges as well as the main text area. The surrounding (gray)
+%D makes the main page stand out and is suitable for viewing in spread mode.
+%D
+%D Since this style is under constant construction, messing around with settings
+%D will produce unwanted side effects. So, if some feature or settings is needed,
+%D let me know.

+
+This is the zero issue of a range of \CONTEXT\ related publications, in most
+cases short introductions to new functionality. The style may be used by users
+for providing similar documents, but preferably not for other purposes, since it
+may confuse readers in their expectations.
+
+We've chosen a layout which is more functional than beautiful. This layout
+provides several text areas: headers and footers, margins and edges as well as a
+main text area. The surrounding (gray or color) makes the main page (which is
+slightly smaller than A4) stand out and is suitable for viewing in spread mode.
+
+The documents produced at \PRAGMA\ are called {\bf This Way}, user documents gets
+the title {\bf My Way}. The \PRAGMA\ issues are numbered. We strongly advise you
+not to use the \type {mag-} prefix for your issues, since this may lead to
+clashes with files distributed by \PRAGMA.

+%D \macros
+%D   {setupbodyfont}
+%D
+%D This is just another environment for typesetting interactive presentations. I
+%D wrote this module on behalf of a course I gave for the United Kingdom \TeX\ users
+%D group.
+
+\setupbodyfont[postscript,14.4pt]
+
+%D \macros
+%D   {setupcolors,definecolor}
+%D
+%D I started using dark blue for the navigational elements. In that context, dark
+%D red is a logical choice for the contrast color. While playing around with the
+%D navigational elements I decided to use the not so dominant color yellow for the
+%D status bar.
+%D
+%D A few days before I wrote this style, the recent acquisition of Mondriaans last
+%D painting by the Dutch governement was a hot topic in the Dutch news scenary.
+%D Therefore I decided to replace the rather dull title page by something more
+%D colorful, in mondriaan colors, but far more random than any of his paintings. For
+%D consistence we remap the already defined primary colors.
+%D
+%D The \MKIV\ version is adapted abit so that the title is better visible.

+%D \macros
+%D   {setuppapersize}
+%D
+%D As usual, we take a screen oriented paper size:
+
+\setuppapersize
+  [S6][S6]
+
+%D \macros
+%D   {setuplayout,setupinteractionscreen}
+%D
+%D The layout definition fits into this $600\times450$ point area, but the
+%D dimensions are somewhat diffused by the text background offset.
+
+\setuplayout
+  [width=530pt,
+   height=400pt,
+   header=0pt,
+   footer=0pt,
+   backspace=15pt,

+   rightedge=30pt]
+
+\setupinteractionscreen
+  [option=max]
+
+%D \macros
+%D   {setupbackgrounds}
+%D
+%D Both the page and the text area have a gray background. The \type {[text,text]}
+%D area also has an offset. Later we will see that we have to compensate for that in
+%D the navigational areas.
+
+\setupbackgrounds
+  [page]
+  [background=color,
+   backgroundcolor=PageColor]
+
+\setupbackgrounds
+  [text][text]
+  [background=color,
+   backgroundcolor=TextColor,
+   backgroundoffset=5pt]
+
+%D \macros
+%D   {setupinteraction}
+%D
+%D For convenient navigation, we turn on interaction.
+
+\setupinteraction
+  [state=start,
+   menu=on,
+   color=UserColor,
+   contrastcolor=NoneColor]
+
+%D \macros
+%D   {setupsubpagenumber}
+%D
+%D When navigating the document, we keep the title page out of sight, therefore we
+%D use sub page numbers.
+
+\setupsubpagenumber
+  [state=start,
+   way=bytext]
+
+%D \macros
+%D   {setupinteractionmenu}
+%D
+%D There is only one interaction menu, located in the right edge of the screen. Both
+%D offsets enlarge the edge by the same amount as the text background offset.
+
+\setupinteractionmenu
+  [right]
+  [state=start,
+   frame=off,
+   strut=no,
+   offset=0pt,
+   inbetween=,
+   bottomoffset=-5pt,
+   topoffset=-5pt]
+
+%D \macros
+%D   {startinteractionmenu}
+%D
+%D The menu itself is not that spectacular. We use the start||stop alternative for
+%D setting the content. The macro \type {\interactioncolor} expands into either the
+%D interaction color or the contrast color, the latter only when no jump is
+%D possible.
+
+\startinteractionmenu[right]
+    \setupinteraction[color=GotoColor]
+    \but [previoussubpage] \Triangle {90}\hsize\interactioncolor \\

+    \vskip-5pt
+    \but [NextJump]        \Triangle  {0}\hsize{NoneColor}       \\
+\stopinteractionmenu
+
+%D \macros
+%D   {setupinteractionbar}
+%D
+%D The interaction bar at the bottom is also larger than the normal width of the
+%D bottom area.
+
+\setupinteractionbar
+  [width=\textwidth,
+   height=\bottomheight,
+   distance=10pt,
+   color=NoneColor,
+   contrastcolor=StepColor]
+
+%D \macros
+%D   {setupbottomtexts}
+%D
+%D The bar is centered in the middle.
+
+\setupbottomtexts
+  [{\interactionbar[alternative=f]}]
+
+%D We can exit viewing with a close button, located on the rightmost bottom area.
+
+\unexpanded\def\CloseButton
+  {\ifnum\realpageno>\plusone

+
+\setupbottomtexts
+  [edge][][\CloseButton]
+
+%D \macros
+%D   {definesymbol,setupitemize}
+%D
+%D Because some prominent things are rectangular or triangular, we prefer some
+%D different symbols in itemizations:
+
+\definesymbol[1][\blacktriangleright]
+\definesymbol[2][\blacktriangledown]
+\definesymbol[3][\blacktriangleright]
+\definesymbol[4][\blacktriangledown]

+%D   {TitlePage,defineoverlay,button,setupalign,
+%D    setupbackgrounds,setupinteraction,setupinteractionbar,

+%D
+%D Now the main layout and navigational definitions are done, it makes sense to
+%D define and tune some structuring commands. First we build the titlepage.

+
+%D \macros
+%D   {Topic, Nopic, Subject,
+%D    definehead, setuphead}
+%D
+%D We use \type {\Topic} and \type {\Subject} instead of chapters and sections. The
+%D \type {\Nopic} alternative is meant for internal use.
+
+\definehead [Topic]   [chapter]
+\definehead [Nopic]   [title]
+\definehead [Subject] [section]
+
+\setuphead
+  [Topic,Nopic]

+\setuphead

+   page=yes,
+   continue=no,
+   style=\bfa]
+
+%D \macros
+%D   {Topics, Subjects,
+%D    setuplist, placelist, startcolumns}
+%D
+%D This style is meant for the more large presentations, and therefore provided for
+%D a list of topics as well as local lists of subjects. When many topics are
+%D introduces, the list is typeset in columns.
+
+\setuplist
+  [Topic,Subject]
+  [alternative=g,
+   interaction=all,
+   before=,
+   after=]
+
+\setuplist

+%D Just another one-time used Bacho\TEX\ presentation style that I found back
+%D when cleaning up old files. It's just simple pages in a shape and this time
+%D we hook it into a section command.

+%D This is the third environment for typesetting interactive presentations. I used
+%D this style for a talk on \TEX\ and \JAVASCRIPT\ at \TUG98, mainly because I
+%D didn't want to use the same style three times. Therefore this is a rather simple,
+%D silly style.

+%D \macros
+%D  {setupbodyfont}
+%D
+%D We use a large bodyfont. Combined with the fancy
+%D background, this does not leave that much room for text, but
+%D presentations should use much text anyway.

+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+\startmodule[present-organic]
+
+%D This style is made in the process or writing the \METAFUN\ manual. It exploits a
+%D few tricks, like graphics calculated using positional information. It also uses
+%D the (at that moment) new menu list placement alternative. If you forget about the
+%D definition of the button shapes, which is complicated in any system, this style
+%D is not even that hard to follow. Watch how the left side of the buttons follow
+%D the right side of the text graphic.
+%D
+%D While playing bit with this style, the random alternative made me think of those
+%D organic building with non equal windows (we have a few in The Netherlands), so I
+%D decided to label this style as \type {pre-organic}.
+%D
+%D At the end of this file, there is a small test file, so when you process this
+%D file with \TEXEXEC\ and the options \type {--mode=demo} and \type {--pdf}, you
+%D will get a demo document.
+%D
+%D We use one of the standard screen \quote {paper} sizes, and map it onto the same
+%D size, so that we get a nicely cropped page.
+
+\setuppapersize
+  [S6][S6]
+
+%D Like in the \METAFUN\ manual, we use the Palatino as main bodyfont. This font is
+%D quite readable on even low resolution screens, although I admit that this style
+%D is developed using an $1400\times1050$ pixel LCD screen, so I may be biased.
+
+\setupbodyfont[pagella]
+
+%D The layout specification sets up a text area and a right edge area where the
+%D menus will go. Watch the rather large edge distance. By setting the header and
+%D footer dimensions to zero, we automatically get rid of page body ornaments, like
+%D the pagenumber.
+
+\setuplayout
+  [topspace=48pt,
+   backspace=48pt,
+   cutspace=12pt,
+   width=400pt,

+   rightedge=88pt,
+   rightedgedistance=48pt,
+   header=0cm,
+   footer=0cm,
+   height=middle]
+
+%D We use a moderate, about a line height, interparagraph white space.
+
+\setupwhitespace
+  [big]
+
+%D Of course we use colors, since on computer displays they come for free.
+
+\definecolor [red]              [r=.75]
+\definecolor [yellow]           [r=.75,g=.75]

+\definecolor [TextColor]        [white]
+\definecolor [OrnamentColor]    [red]
+\definecolor [InteractionColor] [red]
+\definecolor [ContrastColor]    [gray]
+
+%D This is an interactive document, so we enable interaction. In this style, we
+%D disable the viewer's \quote {highlight a hyperlink when it's clicked on} feature.
+%D We will use a menu, so we enable menus. Later we will see the contract color
+%D |<|hyperlinks gets that color when we are already on the location|>| in action.
+
+\setupinteraction
+  [state=start,
+   click=off,
+   color=InteractionColor,
+   contrastcolor=ContrastColor,
+   menu=on]
+
+%D The menu itself is set up as follows. Because we will calculate menubuttons based
+%D on their position on the page, we have to keep track of the positions. Therefore,
+%D we set the \type {position} variable to \type {yes}.
+
+\setupinteractionmenu
+  [right]
+  [frame=off,
+   position=yes,
+   align=middle,
+   topoffset=.75cm,    % watch out, these are negative in mkii
+   bottomoffset=.75cm, % watch out, these are negative in mkii
+   color=gray,
+   contrastcolor=gray,
+   style=bold,
+   before=,
+   after=]
+
+%D The menu content is rather sober: a list of topics (later we will define the
+%D command that generates topic entries), and a close button.
+
+\startinteractionmenu[right]
+    \placelist[Topic][alternative=right]
+    \vfill
+    \but [CloseDocument] close \\
+\stopinteractionmenu
+
+%D We have now arived at the more interesting part of the style definition: the
+%D graphic that goes in the page background. Because this graphic will change, we
+%D define a usable \METAPOST\ graphic. Page backgrounds are recalculated each page,
+%D opposite to the other backgrounds that are calculated when a new background is
+%D defined, or when repetitive calculation is turned on.

+%D \macros

+%D
+%D The titlepage is rather simple and can be typeset in two ways:
+%D
+%D \starttyping
+%D \StartTitlePage
+%D text \\ text \\ text
+%D \StopTitlepage
+%D \stoptyping
+%D
+%D or more straightforward:
+%D
+%D \starttyping
+%D \TitlePage{text\\text\\text}
+%D \stoptyping
+%D
+%D The first alternative can be used for more complicated title pages.

+%D
+%D A presentation after loading this module looks like:
+%D
+%D \starttyping
+%D \TitlePage {About Whatever\\Topics}
+%D
+%D \Topics {Todays Talk}
+%D
+%D \Topic {Some topic}
+%D
+%D \Subject {Alfa}
+%D
+%D .....
+%D
+%D \Subject {Beta}
+%D
+%D .....
+%D \stoptyping
+
+%D \macros
+%D   {definehead}
+%D
+%D The commands \type{\Topic} and \type{\Subject} are defined as copies of head. We
+%D use \type{\Nopic} for internal purposes.
+
+\definehead [Topic]   [chapter]
+\definehead [Subject] [section]
+
+\definehead [Nopic]   [title]
+
+%D \macros
+%D   {setuphead}
+%D
+%D Because chapters and sections do not make sense in presentations, we use our own
+%D command for typesetting the titles. Sectionnumbers are of course hidden from
+%D viewing. Each topic is followed by a list of subjects that belong to the topic.
+
+\setuphead
+  [Topic,Nopic,Subject]
+  [command=\HeadLine,
+   page=yes,
+   style=\bfb,
+   after=\blank,
+   sectionnumber=no]
+
+\setuphead
+  [Topic]
+  [after=\PlaceSubjectList]
+
+\setuphead
+  [Subject]
+  [continue=no]
+
+%D \macros
+%D   {framed, midalined}
+%D
+%D The command used to typeset the head lines is rather simple. We just center the
+%D framed title. The frame macro optimizes the alignment and at the same time
+%D enables us to typeset a nice colored rule.
+
+\unexpanded\def\HeadLine#1#2%
+  {\midaligned
+     {\framed
+        [framecolor=BackgroundColor,
+         rulethickness=1pt,

+         align=middle,
+         strut=no]
+        {#2}}}
+
+%D \macros
+%D   {setuplist}
+%D
+%D The subject list is automatically placed. We center each subject line by using
+%D one of the default alternatives (g). We could have said:
+%D
+%D \starttyping
+%D \setuplist
+%D   [Subject]
+%D   [alternative=none,
+%D    command=\SubjectListLine,
+%D    interaction=all]
+%D
+%D \def\SubjectListLine#1#2#3%
+%D   {\midaligned{#2}}
+%D \stoptyping
+%D
+%D But why should we complicate things when we can use alternative~\type{g}. The
+%D test is only needed if one does not automatically goes a new page with each
+%D subject.
+
+\unexpanded\def\PlaceSubjectList
+  {\blank
+   \determinelistcharacteristics[Subject]
+   \doifmode{*list}{\placelist[Subject]}}
+
+\setuplist
+  [Subject,Topic]
+  [alternative=g,
+   interaction=all,

+
+% %D \macros
+% %D   {setuptexttexts}
+% %D
+% %D The topics will be listed in the right edge, using:
+%
+% \setuptexttexts
+%   [edge]
+%   [][\TopicList]
+
+%D \macros
+%D   {setuplist, placelist,startinteractionmenu}
+%D
+%D The actual topic list is typeset using a \type{\vbox}. We have to specify
+%D \type{criteriumcriterium=all} because otherwise no list will be typeset. (By
+%D default lists are typeset locally.)
+
+\startinteractionmenu[right]
+  \placelist

+
+%D \macros
+%D   {setupbackgrounds, overlaybutton}
+%D
+%D During a presentation, we want to use the cursor to point to parts of the text.
+%D Furthermore we want to be able to jump to the next page, without the need to move
+%D the cursor on buttons. Therefore we make the text part of the screen into an
+%D invisible button.
+%D
+%D In \MKII\ we put a button in he texttextsm here we just use an extra background.

+%D The theme of Bacho\TeX\ was \quote {Getting \TEX\ out of the closet}. And, as I'm
+%D always a bit sceptical about efforts to get a specialized toolbox like \TEX\
+%D accepted in a large scale generic user base, I decided to give a talk dedicated
+%D to Jerzy (the always optimistic organizer). (One can actually wonder if \TEX\ was
+%D ever hidden in a closet.) And, because I had to get the attention of some nephew
+%D and nieces I took there I gave the presentation without beamer but on my phone.
+%D On such a device one just swipes but I still added two buttons. Watch the small
+%D full|-|hd|-|ratio paper dimensions and 6 point font size.

+%D In the process of making a couple of simple styles for \EUROTEX\ 99, I came to
+%D this one. The joke is in the pagenumber. This style can be used for short
+%D presentations with much text.

+%D We only use two colors, named \type {ColorOne} and \type {ColorTwo}:
+
+\definecolor [ColorOne] [r=.6,g=.4,b=.4]
+\definecolor [ColorTwo] [r=.4,g=.6,b=.6]
+
+%D If you've looked at the demo file, you will have noticed that the background
+%D consists of four pieces: two filled rectangles and two half numbers. In older
+%D versions these are put on the page using four overlays, here we use a much
+%D cleaner implementation is the following. If you hate \METAPOST, you can run
+%D this style in the specified mode:

+\stopuseMPgraphic
+
+%D We use the simple label typesetting present in \METAPOST\ because digits are
+%D seldom kerned so real \TEX ing is not needed. As in the previous method, we let
+%D the graphics overlap so that we don't get white lines due to rounding problems in
+%D viewers.
+%D
+%D We put a button behind the text (this overlay is calculated each page).

+%D I made this style when I had to give a presentation on the \MAPS\ bibliography
+%D production for several user group meetings. This style is rather tuned for
+%D combinations of examples and explanations. The colors match the \MAPS\
+%D bibliography colors.

+%D A couple of years later, in 2001 this style was documented and made public. While
+%D documenting, I also changed box building on top of overlays into the now
+%D available layer positioning. So, this styles demonstrates quite some tricks.
+%D
+%D I'm sure that nowadays it can be done with less code but therei sno real need to
+%D rewrite history.

+%D We will present samples and explanation pair||wise, so we need a hyperlink that
+%D skips a page. Contrary to \MKII\ we put the next button in the page background and
+%D the two windows get buttons that toggle between them. This is easier.
+
+\defineoverlay [nextpage]     [\overlaybutton{nextpage}]
+\defineoverlay [previouspage] [\overlaybutton{previouspage}]

+
+%D Layers are normally used to position multiple content on a specific overlay. Here
+%D we will use them to position only and since the samples and text will swap place,
+%D we will use quite a few layers.
+
+\defineoverlay [text]   [\composedlayer{text}]
+\defineoverlay [sample] [\composedlayer{sample}]
+\defineoverlay [common] [\composedlayer{common}]
+
+%D There are three positions. When combined, the sample and text windows overlap,
+%D otherwise the lone window is centered. We could have used one layer and reversed
+%D the order by setting the \type {direction} parameter, but this approach is more
+%D readable.
+
+\definelayer
+  [text]
+  [x=\makeupwidth,
+   y=\makeupheight,
+   location=lt,
+   hoffset=-\FrameSkip,
+   voffset=-\FrameSkip]
+
+\definelayer
+  [sample]
+  [hoffset=\FrameSkip,
+   voffset=\FrameSkip]
+
+\definelayer
+  [common]
+  [x=.5\makeupwidth,
+   y=.5\makeupheight,
+   location=c]
+
+%D The topic is put in the lower right corner of the text window.
+
+\defineoverlay [topic] [\composedlayer{topic}]
+
+\definelayer
+  [topic]
+  [x=\FrameWidth,
+   y=\FrameHeight,
+   location=lt,
+   hoffset=-\FrameOffset,
+   voffset=-\FrameSkip]
+
+%D The topic is put in a framed box. That way we can make sure that it gets a
+%D background, which looks better when it covers something else. Otherwise we could
+%D have stuck to:
+%D
+%D \starttyping
+%D \def\Topic#1%
+%D   {\setlayer[topic]{\color[PageColor]{\bfb\setstrut#1}}}
+%D \stoptyping
+%D
+%D But, we go for the nice alternative:
+
+\unexpanded\def\Topic#1%
+  {\doifsomething{#1}
+     {\setlayer [topic]
+        {\bfb\setstrut
+         \inframed
+           [frame=off,
+            foregroundcolor=PageColor,
+            offset=0pt,
+            background=color,
+            backgroundcolor=TextColor]
+           {#1}}}}
+
+%D The sample as well as the explanation will be collected in a buffer. That way we
+%D can reuse the content. We could have used a box instead, but can we be sure that
+%D the content is not adapting itself? So, buffers we use.
+
+\resetbuffer[sample]
+\resetbuffer[text]
+
+%D Both the sample and explanation are kind of windowed.
+
+\defineframedtext
+  [SampleText]
+  [width=\FrameWidth,
+   height=\FrameHeight,
+   offset=\FrameOffset,
+   frame=off,
+   align=normal,
+   strut=no,
+   before=,
+   after=,
+   background=background]
+
+%D We safe some keying in by combining things in one macro.
+
+\unexpanded\def\DoSampleText#1#2#3% kind layer overlays
+  {\setupframedtexts[SampleText][background={background,#3}]
+   \setlayer[#2]
+     {\startSampleText[none]
+        \setups[#1]
+        \getbuffer[#1]
+      \stopSampleText}}
+
+\unexpanded\def\StartSample{\dostartbuffer[sample][StartSample][StopSample]}
+\unexpanded\def\StartText  {\dostartbuffer[text]  [StartText]  [StopText]}
+
+%D The following definitions apply at the outer level.
+
+\unexpanded\def\StopSample

+   \stopstandardmakeup
+   \resetbuffer[text]}
+
+\setupbackgrounds[page][background={color,nextpage}]
+\setupbackgrounds[text][background=common]
+
+%D When we combine sample and text, we get slightly different definitions. As you
+%D can see we generate two pages. Watch how we manipulate the order of the overlays
+%D and teh nature of the buttons. Here some abstraction really pays off.

+Agriculture is a fairly recent human invention, and in many ways it was one of
+the great stupid moves of all time. Hunter|-|gatherers have thousands of wild
+sources of food to subsist on. Agriculture changed that all, generating an
+overwhelming reliance on a few dozen domesticated food sources, making you
+extremely vulnerable to the next famine, the next locust infestation, the next
+potato blight. Agriculture allowed for stockpiling of surplus resources and thus,
+inevitably, the unequal stockpiling of them --- stratification of society and
+the invention of classes. Thus, it allowed for the invention of poverty. I think
+that the punch line of the primate|-|human difference is that when humans
+invented poverty, they came up with a way of subjugating the low|-|ranking like
+nothing ever seen before in the primate world.
