+--
+-- This is a follow up on typo-dua which itself is a follow up on t-bidi by Khaled Hosny which
+-- in turn is based on minibidi.c from Arabeyes. This is a further optimizations, as well as
+-- an update on some recent unicode bidi developments. There is (and will) also be more control
+-- added. As a consequence this module is somewhat slower than its precursor which itself is
+-- slower than the one-pass bidi handler. This is also a playground and I might add some plugin
+-- support. However, in the meantime performance got a bit better and this third variant is again
+-- some 10% faster than the second variant.
+--
+-- ... some patches and updates applied
+-- ... some code can be removed
+-- ... has to be kept in sync with context
+-- ... mtxrun --script interface
+--
+-- ... this feature is more fun than useful
+-- ... this way we can use it to check what scite / uniscribe sees (as scintila is weak on

--- STATUS
+-- 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.
 --
--- 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)
+-- 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.
 --
--- wish: access to all scite properties and in fact integrate in scite
+-- 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.
 --
+-- 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.
+-- 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) 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

--- 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.
+-- The basic code hasn't changed much but we had to adapt a few times to changes in

--- 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

--- 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

+    {\bf the macro package's view:} just a font like any other but it needs to configure
+    some extra color related properties
+\stopitem
+\startitem
+    {\bf the engine's view:} depending on the technology a normal font that needs a bit
+    special treatment or needs to be dealt with as collection of graphics
+\stopitem
+\startitem
+    {\bf the viewer's view:} regular outline glyphs or images tagged as kind of
+    characters so that their unicode representation can be cut and paste
+\stopitem
+\startitem
+    {\bf the user's view:} more pictures than glyphs although some people one can
+    communicate using them
+\stopitem
+\stopitemize
+
+So, in practice, for most \TEX\ users it's probably not a high priority font but more a fun
+one.

+\startsubject[title=Technologies]
+
+As each vendor came up with something, we have to deal with a all kinds of formats. And or
+course, as eagerness pushes things on the market before it's perfect we now have to deal
+with all of them.
+
+\startitemize
+\startitem
+    {\bf overlapping glyphs:} this technique uses the \type {colr} and \type {cpal} tables
+    and is actually a quite clean technology, you can combine in different ways
+\stopitem
+\startitem
+    {\bf svg graphics:} this technique uses the \type {svg} table that contains a svg vector
+    image
+\stopitem
+\startitem
+    {\bf bitmap graphics:} this technique uses for instance \type {sbix} tables that can have
+    various graphic images
+\stopitem
+\stopitemize
+
+The first two are already supported in the \CONTEXT\ font loader and processor
+for a while, the last one was added recently.
+

+
+Only the overlapping method is useable for the tens of thousands of skin tone combinations of
+families, (kissing) couples, and professions.

+\startitem
+    {\bf the macro package's view:} just a font but with many possible variations

+\stopitem
+\startitem
+    {\bf the engine's view:} an abstraction not different from other fonts but
+    that needs a special treatment in the backend
+\stopitem
+\startitem
+    {\bf the viewer's view:} a font to be displayed like any other with outlines
+    in cff of ttf format
+\stopitem
+\startitem
+    {\bf the user's view:} an opentype font with possibly surprising shapes of
+    which you need to know a bit more than usual if you want to profit from it
+\stopitem
+\stopitemize
+
+So, in practice, for most \TEX\ users it's just a font that has to be supported by
+\TEX\ and friends.
+
+\stopsubject
+
+\startsubject[title=Starting point]
+
+\startitemize
+\startitem
+    The OpenType 1.8 specification at the MicroSoft website defined the extra
+    tables and explains bits and pieces.
+\stopitem
+\startitem
+    There a few fonts that have relevant tables (not all) and implement variants
+    as well as features.
+\stopitem
+\startitem
+    There are some posts on the internet that show a bit about axis and other things
+    that go on in these fonts.
+\stopitem
+\startitem
+    Luckily we have ways (in \CONTEXT) to explore what goes on in these fonts and
+    how they could look.
+\stopitem
+\startitem
+    Condition: no tricks, no fuzzy heuristics, just the specification should be
+    enough.
+\stopitem
+\stopitemize
+
+\stopsubject
+
+\startsubject[title=Implementation steps]
+
+\startitemize
+\startitem
+    First try to render variants in order to see what we're dealing with. This was not too
+    hard (starting with cff) because we have already virtual font support.
+\stopitem
+\startitem
+    Next try to load the relevant tables and figure out what these deltas and such really
+    mean and how axis and regions and \unknown\ have to be applied.
+\stopitem
+\startitem
+    Try to make it all work on a real piece of text, so not only shapes but also features
+    and dimensions.
+\stopitem
+\startitem
+    Finally make sure that the font can get embedded as a normal font and not as inline
+    (tagged) graphic.
+\stopitem
+\startitem
+    Also, try to generalize the helpers and methods in such ways that we can experiment
+    with additional tricks (after all, \TEX\ is about control).
+\stopitem
+\startitem
+    Todo: once there are more fonts (with the right data tables), check the code with the
+    specification.

+\StartTopic{loading fonts}
+
+\StartSteps
+
+\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
+
+\StopSteps
+
+\StopTopic
+
+\StartTopic{making it work}
+
+\StartSteps
+
+\StartItem the \FONTFORGE\ library loads the fonts into memory \FlushStep \StopItem
+\StartItem the internal data structures are mapped into a \LUA\ table  \FlushStep \StopItem
+\StartItem we enhance this table a bit (extra hashes as well as rearranging glyphs)  \FlushStep \StopItem
+\StartItem we save the table in a cache and compile it to bytecode \FlushStep \StopItem
+\StartItem after that reloading is fast and efficient \FlushStep \StopItem
+\StartItem when defining a font instance we share data as much as possible \FlushStep \StopItem
+\StartItem the open type specific table is translated into a \TFM\ one \FlushStep \StopItem
+\StartItem but for handling features we keep the original table available \FlushStep \StopItem
+
+\StopSteps
+
+\StopTopic
+
+\StartTopic{user control}
+
+\StartSteps
+
+\StartItem in context \MKIV\ currently we provide several interfaces \FlushStep \StopItem
+\StartItem the \XETEX\ syntax is (more or less) supported \FlushStep \StopItem
+\StartItem there is a higher level interface to associating features with fonts  \FlushStep \StopItem
+\StartItem there will be a font instance independent feature switch mechanism \FlushStep \StopItem
+\StartItem there can be generic treatments unrelated to the specific font \FlushStep \StopItem
+\StartItem fonts can be accessed by various names \FlushStep \StopItem
+\StartItem but \unknown\ using features demands that users know what they're doing \FlushStep \StopItem
+
+\StopSteps
+
+\StopTopic
+
+\StartTopic{zapfino}
+
+\StartSteps
+
+\StartItem we needed this exercise as a prelude to handling arab (which we cannot really read) \FlushStep \StopItem
+\StartItem this font provides a good testbed because has many features defined \FlushStep \StopItem
+\StartItem the associated \LUATEX\ tables are rather large \FlushStep \StopItem
+\StartItem there can be hundreds of lookups per character with lookahead and backtracking \FlushStep \StopItem
+\StartItem when writing support for such features, bugs in such fonts complicate matters \FlushStep \StopItem
+\StartItem visually checking the output is complicated by the fact that wrong alternatives may look good \FlushStep \StopItem
+\StartItem we must make sure that \TEX's other mechanisms don't spoil the game \FlushStep \StopItem
+\StartItem special care is needed for lookups that involve spaces \FlushStep \StopItem

+The width of the space and its stretch and shrink are taken from the font. The so
+called emspace is the reference for much spacing related parameters. It is the
+width of character \type {0x2014}. The regular space width is taken from \type
+{0x0020}, the space character. When there is no space character, in the case of a
+monospaced font we take the emwidth, otherwise we take half the emwidth. As a
+last resort we can take the average width of characters. And of even that fails
+we take half of the font units. When there is no emwidth that one is set to the
+font units.
+
+In the \CONTEXT\ font loader we use a stretch that is 1/2 of the width of a space
+and the shrink is 1/3 the width of a space, so we use values that are quite

+
+When \TEX\ loads a font it gets stored in an internal format. Although \LUATEX\
+can still load \TFM\ files, normally we will load font data using \LUA\ and then
+pass it to \TEX. When that is done the font is basically frozen. After all, once
+you entered text and that text has been processed to a sequence of glyphs, the
+backend has to be sure that it can include the right data in the result. What
+matters there is:
+
+\startitemize[packed]
+\startitem the width of a glyph \stopitem
+\startitem the index of a glyph in the font \stopitem
+\startitem properties of a font, like its name \stopitem
+\startitem all kind manipulations don't with a virtual glyph\stopitem
+\stopitemize
+
+So, changing an already used glyph is not done. But, adding a new one should not
+be a big deal. So, starting with \LUATEX\ 1.0.5 we can add characters (that
+become glyphs) to a font after it got passed to \TEX.
+
+Of course there are some limitations to this. For instance, when \OPENTYPE\
+features are needed, you also need to extend that bit and it's not that trivial.
+But adding independent special characters is no problem. Also, you can decide to
+replace an already processed glyph by another one newly created with the same
+dimensions but a different rendering.
+
+Here I'll give a few (simple) examples. First we define a helper that creates a
+rule. After that we use all kind of \CONTEXT\ data structures and helpers but the
+general setup is not that complicated.

+Of course, when one defines a font to be passed to \TEX\ it needs to conform to
+the standard. The \LUATEX\ manual describes what parameters and other properties
+have to be set. We cheat and copy the so called null font. We also create a fonts
+sub table. In such a table, a reference to id zero will be resolved to the id of
+the font.
+
+After defining the font table, we pass it to \TEX\ with \type {font,define} watch
+how we also pass an already reserved id. Then we add some characters and we also
+replace character 122 which is no problem because, after all, we haven't used it

+When defining virtual characters you need to keep in mind that there are limits to
+how large a character can be. If you go too far \LUATEX\ will quit with a scale
+related message.
+
+In \CONTEXT\ there are a couple of mechanism that were implemented when \LUATEX\
+came around that can be updated to use the tricks described here. I'm not sure if
+I'll do that. After all, it works now too. The main benefit of the fact that we
+can extend a font within reasonable bounds is that future mechanism can benefit
+from it.
+
+There is one thing to keep in mind. Say that we define a font like this:
+
+\starttyping
+\definefont[MyDemoOneX][Serif*myextension-one]
+\stoptyping
+
+Because we already defined a font with the same size, we automatically get the characters
+\type {6000} upto \type {6003}. If we don't want this and want a fresh instance, we can do:
+
+\starttyping
+\definefontfeature[myextension-two][default][myextension=2]
+\definefont[MyDemoOneX][Serif*myextension-two]
+\stoptyping
+
+or just:
+
+\starttyping
+\definefont[MyDemoOneX][Serif*default]
+\stoptyping
+
+Normally this kind of hackery is not arbitrary and part of a well designed set up
+so one knows what one gets.

+\startsection[title=Introduction]
+
+In this chapter topics that don't fit in the previous chapters are
+collected.
+
+\stopsection
+
+\startsection[title=Extra characters]
+
+In one of our projects we need a small (high) minus and here we discuss
+one way of achieving this. An option is to define a new character
+and use a font feature to add it, as in:
+
+\starttyping
+\startluacode
+  local function addextraminus(tfmdata)
+    fonts.helpers.addprivate(tfmdata, "smallminus", ... ) -- see below
+    fonts.helpers.addprivate(tfmdata, "highminus",  ... ) -- see below
+  end
+  fonts.constructors.newfeatures.otf.register {
+    name        = "extraminus",
+    description = "extra minus symbols",
+    default     = true,
+    manipulators = {
+      base = addextraminus,
+      node = addextraminus,
+    }
+  }
+\stopluacode
+\stoptyping
+
+However, why make it an option when we can just add it to any font. So,
+we can end up with just:
+
+\typebuffer[extraminus] % already defined before loading fonts
+
+It is important to do this before fonts get loaded. Next we need to decide how to
+access these characters. A straightforward way is:
+
+\startbuffer
+\def\smallminus{\privatechar{smallminus}}
+\def\highminus {\privatechar{highminus}}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+An alternative is:
+
+\starttyping
+\definemathcommand [smallminus] [ord] {\privatechar{smallminus}}
+\definemathcommand [highminus]  [ord] {\privatechar{highminus}}
+\stoptyping
+
+but that fails in text mode. So, we can consider:
+
+\starttyping
+\def\smallminus{\mathortext{\mathord{\privatechar{smallminus}}}{\privatechar{smallminus}}}
+\def\highminus {\mathortext{\mathord{\privatechar {highminus}}}{\privatechar {highminus}}}
+\stoptyping
+
+or more compact
+
+\starttyping
+\def\smallminus{\mathortext\mathord\firstofoneargument{\privatechar{smallminus}}}
+\def\highminus {\mathortext\mathord\firstofoneargument{\privatechar {highminus}}}
+\stoptyping
+
+What method you choose depends on usage. With the first, simple definitions we
+get this:
+
+\startbuffer
+[\getprivateslot{smallminus}] [\getprivatechar{smallminus}] [\smallminus] $[\smallminus]$\par
+[\getprivateslot {highminus}] [\getprivatechar {highminus}] [\highminus ] $[\highminus ]$\par
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Because we are fully expandable we can even use this in:
+
+\startbuffer
+\bTABLE[aligncharacter=yes,alignmentcharacter={text->\smallminus}]
+  \bTR \bTD \mathminus100\smallminus00+ \eTD \eTR
+  \bTR \bTD           100\smallminus00  \eTD \eTR

+\eTABLE
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+With the other definitions the alignment would not work. If you need both then
+you can define different commands for text and math.
+

+
+\startsection[title=Tabular numbers]
+
+Some font features are meant to be used in controlled situations. An example is
+the \type {tnum} feature that triggers so called \quote {tabular figures} meaning
+numbers that have equal widths. Its opposite feature is \type {lnum} or lining
+figures. We have two predefined \CONTEXT\ font features for this:
+
+\starttyping
+\definefontfeature [inlinenumbers]  [lnum=yes,tnum=no]
+\definefontfeature [tabularnumbers] [tnum=yes,lnum=no]
+\stoptyping
+
+Some mechanisms in \CONTEXT\ had better be aware of this and one of them is the
+alignment mechanism in tables.

+\startsection[title={A virtual hack}]
+
+Here is some virtual trickery. A virtual font is just a font but instead of a
+character being a reference to a slot in a font (often via an index) it
+constructs a glyph from whatever characters, rules, displacements, inline \PDF\
+code, etc. We use them a lot deep down in \CONTEXT. The next example defines two
+characters represented by rules. This definition is about as minimalistic as
+reasonable and demonstrates how we can apply expansion (aka hz) to such a font.
+\footnote {You need \LUATEX\ 1.08 or later for this.} We store the font id (a
+number) in a macro. Watch how we don't refer to a glyph in a font. Because we
+don't specify its type as \type {virtual} we can leave out the \type {font}
+table. After all, we don't refer to real glyphs.

+With \CONTEXT\ you can typeset in two directions: from left to right and from
+right to left. In fact you can also combine these two directions, like this:
+
+\startbuffer
+There are many {\righttoleft \maincolor \it scripts in use} and some run into the
+other direction. However, there is {\righttoleft \maincolor \it no fixed relation
+{\lefttoright \black \it between the} direction of the script} and cars being
+driven left or right of the road.
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Even someone not familiar with right to left typesetting can see what happens
+here, or not? In fact Luigi Scarso pointed out that the \type {fixed} reversed
+into {\righttoleft \type {fixed}} but not in the example where {\bf fixed}
+becomes {\righttoleft \bf fixed}. This signals an important property of the way
+the text gets processed: you input something, at some points font features get
+applied (like ligatures) and in the end the resulting glyph stream is reversed.
+By that time the combination of {\bf f}+{\bf i} has become {\bf fi}! So, be
+prepared for surprises.
+
+This manual is written by a left to right user so don't expect a manual on
+semitic typesetting. Also don't expect a (yet) complete manual. I'll add whatever
+comes to mind. This is not a manual about Hebrew or Arabic, if only because I
+can't read any of those scripts (languages). I leave that to others to cover.
+
+{\em This is work in progress! So expect errors and typos.}

+\startchapter[title={Setting up fonts}]
+
+So let's see how Arabic and Hebrew come out:
+
+\startbuffer
+The sentence \quotation {I have no clue what this means.} is translated (by
+Google Translate) into \quotation {\ar \righttoleft ليس لدي أي فكرة عما يعنيه هذا.}
+which is then translated back to \quotation {I have no idea what this means.} so
+maybe arabic has no clue what a clue is. The suggested Arabic pronunciation is
+\quotation {lays laday 'ayu fikrat eamaa yaenih hadha}. Hebrew also likes ideas
+more: \quotation {\he \righttoleft אין לי מושג מה זה אומר}.
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+According to Idris Hamid the Arabic should actually be this: \quotation {\ar
+لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا} and the transliteration \quotation {Laysa
+ladayya ayyu fikratin ʿammā yaʿnihi hādhā}.
+
+The \CONTEXT\ (or any \TEX) ecosystem deals with languages and fonts. Languages
+(that relate to scripts) have specific characteristics, like running from right
+to left, and fonts provide a repertoire of glyphs and features. There is no real
+(standard) relationship between these. In for instance browsers, there are
+automatic fallback systems for missing characters in a font: another font is
+taken. These fallbacks are often not easy to tweak.
+
+In this document we use Dejavu and although that font has Arabic shapes in its
+monospace variant, the serifs come without them (at least when I write this
+down). Before we actually define the bodyfont we hook in some fallbacks. The
+typescript for Dejavu has lines like this:
+
+\starttyping
+\definefontsynonym
+  [SerifBoldItalic]
+  [name:dejavuserifbolditalic]
+  [features=default,
+   fallbacks=SerifBoldItalic]
+\stoptyping
+
+This permits us to do this:
+
+\typebuffer[preamble-fonts]
+
+In addition we set up the languages:
+
+\typebuffer[preamble-languages]
+
+The following example demonstrates what the effects of these commands are:
+
+\startbuffer
+{لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا.}
+{אין לי מושג מה זה אומר.}
+{\righttoleft لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا.}
+{\righttoleft אין לי מושג מה זה אומר.}
+{\ar \righttoleft لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا.}
+{\he \righttoleft אין לי מושג מה זה אומר.}
+{\ar لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا.}
+{\he אין לי מושג מה זה אומר.}
+\stopbuffer
+
+\typebuffer
+
+\startlines
+\getbuffer
+\stoplines
+
+In principle you can also rely on automatic direction changes, for instance
+by using the following command:
+
+\starttyping
+\setupdirections
+  [bidi=global,
+   method=three]
+\stoptyping
+
+But that doesn't do a font switch for you, nor does it do any of the other
+language related settings. It really helps if you properly tag your
+document content, as in:
+
+\starttyping
+{\ar لَيْسَ لَدَيَّ أَيُّ فِكْرَةٍ عَمَّا يَعْنِيهِ هٰذَا.}
+{\he אין לי מושג מה זה אומר.}
+\stoptyping
+
+One reason to set the \type {font} parameter for a language is that it will
+activate the right features in a font. Instead of falling back on some default,
+we can be very specific in what we want to enable.
+
+\stopchapter
+
+\startchapter[title=A mixed layout]
+
+The typesetting engine normally works from left to right and top to bottom. Going
+from right to left actually involved two decisions:
+
+\startitemize[packed]
+\startitem the direction of the display elements, the paragraphs \stopitem
+\startitem the direction of the inline text, the lines \stopitem
+\stopitemize
+
+The first one is kept track of in a state variable. Every paragraph starts with
+a node that carries, among other information, that state. This node is added
+automatically and does not interfere with the typesetting. The inline direction
+is more intrusive as it is marked by nodes that indicate the beginning and end
+of a reversed strip. This mechanism is rather reliable and normally works out
+well. Take this:
+
+\startbuffer
+left {\righttoleft right} left
+left{ \righttoleft right} left
+left {\righttoleft right }left
+left{ \righttoleft right }left
+\stopbuffer
+
+\typebuffer
+
+You can see that we need to be careful with spaces as they can end up inside or
+outside a substream and by swapping next to each other:
+
+\startlines
+\getbuffer
+\stoplines
+
+We can wrap the lines in boxes as in:
+
+\startbuffer
+\hbox{left\space{\bf\righttoleft right}\space left}
+\hbox{left{\bf\space \righttoleft right}\space left}
+\hbox{left\space{\bf\righttoleft right\space}left}
+\hbox{left{\bf\space\righttoleft right\space}left}
+\stopbuffer
+
+\typebuffer
+
+\definecolor[ShineThrough][s=0,a=1,t=.2]
+
+When visualize the spaces we get this:
+
+\startlines\ShineThrough
+\showmakeup[space,hbox]\getbuffer
+\stoplines
+
+The space of a normal and bold font in the same family normally is the same but
+let's mix with a larger size:
+
+\startbuffer
+\hbox{left {\bfa\righttoleft right} left}
+\hbox{left{\bfa\space \righttoleft right} left}
+\hbox{left {\bfa\righttoleft right }left}
+\hbox{left{\bfa\space\righttoleft right }left}
+\stopbuffer
+
+\typebuffer
+
+Now we get the following. As you can see, it really matters where we put the
+braces.
+
+\startlines
+\ShineThrough\showmakeup[space,hbox]\getbuffer
+\stoplines
+
+Once you are accustomed to tagging and \TEX\ you will probably not fall into
+these traps. In \in {figure} [fig:spaces] we show a large version.
+
+\startplacefigure[location=top,title={Watch your spaces!},reference=fig:spaces]
+    \scale
+      [width=\hsize]
+      {\vbox{\ShineThrough\showmakeup[space,hbox]\getbuffer}}
+\stopplacefigure
+
+
+The \type {\righttoleft} command actually has two meanings. This can best be seen
+from an example.
+
+\startbuffer
+\righttoleft \bf How will this come out?
+\stopbuffer
+
+\typebuffer
+
+\start \getbuffer \par \stop
+
+\startbuffer
+And \righttoleft \bf how will this come out?
+\stopbuffer
+
+\typebuffer
+
+\start \getbuffer \par \stop
+
+When we start a paragraph (or in \TEX\ speak: when we are still in vertical mode)
+the paragraph direction as well as the inline direction is set. Otherwise only
+the inline direction is set. There are low level \TEX\ commands (primitives) to
+set the direction but you can best {\em not} use these because we need to do a
+bit more than that.
+
+There are quite some low level commands related to changing directions. Some deal
+with the layout, some with boxes. We might provide more in the future.

+\startchapter[title={The \LUA\ interface}]
+
+We assume that you run \CONTEXT\ \MKIV\ in combination with \LUATEX. Direction
+support in this engine has been improved over time. Originally the \OMEGA\
+(\ALEPH) direction model was used but in the meantime it has been stripped to the
+basics, and what used to be so called whatsits (extension nodes) are now first
+class nodes. In the \LUA\ interface we still support the:
+
+\startitemize[packed]
+\startitem
+    \type {TLT} and \type {TRT} keywords for local par nodes
+\stopitem
+\startitem
+    \type {+TLT}, \type {-TLT}, \type {+TRT} and \type {-TRT} keywords for
+    direction nodes
+\stopitem
+\stopitemize
+
+However, because we use dedicated nodes, and because nodes actually store numbers
+and not strings we also expose the numeric model:
+
+\starttabulate[|l|l|l|]
+\NC 0 \NC \type {TLT} \NC left to right \NC \NR
+\NC 1 \NC \type {TRT} \NC right to left \NC \NR
+\NC 2 \NC \type {LTL} \NC not used in context \NC \NR
+\NC 3 \NC \type {RTT} \NC not used in context \NC \NR
+\stoptabulate
+
+These values are used for local par nodes as well as direction nodes. In addition
+a direction node has a subtype:
+
+\starttabulate[|l|l|l|]
+\NC 0 \NC \type {normal} \NC comparable to \type {+} \NC \NR
+\NC 1 \NC \type {cancel} \NC comparable to \type {-} \NC \NR
+\stoptabulate
+
+The \type {dir} field uses the strings, the \type {direction} field the number
+(both of course share the same internal node variable).

+
+Small is beautiful and this is definitely true for the programming language \LUA\
+(moon in Portuguese). We had good reasons for using this language in \LUATEX:
+simplicity, speed, syntax and size to mention a few. Of course personal taste
+also played a role and after using a couple of scripting languages extensively
+the switch to \LUA\ was rather pleasant.
+
+As the \LUA\ reference manual is an excellent book there is no reason to discuss
+the language in great detail: just buy \quote {Programming in \LUA} by the \LUA\
+team. Nevertheless I will give a short summary of the important concepts but

+\index{functions}
+\index{variables}
+\index{strings}
+\index{numbers}
+\index{booleans}
+\index{tables}
+
+The most basic data type is \type {nil}. When we define a variable, we don't need
+to give it a value:
+
+\starttyping
+local v
+\stoptyping
+
+Here the variable \type {v} can get any value but till that
+happens it equals \type {nil}. There are simple data types like
+\type {numbers}, \type {booleans} and \type {strings}. Here are
+some numbers:
+
+\starttyping
+local n = 1 + 2 * 3
+local x = 2.3
+\stoptyping
+
+Numbers are always floats \footnote {This is true for all versions upto 5.2 but
+following version can have a more hybrid model.} and you can use the normal
+arithmetic operators on them as well as functions defined in the math library.
+Inside \TEX\ we have only integers, although for instance dimensions can be
+specified in points using floats but that's more syntactic sugar. One reason for
+using integers in \TEX\ has been that this was the only way to guarantee
+portability across platforms. However, we're 30 years along the road and in \LUA\
+the floats are implemented identical across platforms, so we don't need to worry
+about compatibility.
+
+Strings in \LUA\ can be given between quotes or can be so called long strings
+forced by square brackets.
+
+\starttyping
+local s = "Whatever"
+local t = s .. ' you want'
+local u = t .. [[ to know]] .. [[--[ about Lua!]--]]
+\stoptyping
+
+The two periods indicate a concatenation. Strings are hashed, so when you say:
+
+\starttyping
+local s = "Whatever"
+local t = "Whatever"
+local u = t
+\stoptyping
+
+only one instance of \type {Whatever} is present in memory and this fact makes
+\LUA\ very efficient with respect to strings. Strings are constants and therefore
+when you change variable \type {s}, variable \type {t} keeps its value. When you
+compare strings, in fact you compare pointers, a method that is really fast. This
+compensates the time spent on hashing pretty well.
+
+Booleans are normally used to keep a state or the result from an expression.
+
+\starttyping
+local b = false
+local c = n > 10 and s == "whatever"
+\stoptyping
+
+The other value is \type {true}. There is something that you need
+to keep in mind when you do testing on variables that are yet
+unset.
+
+\starttyping
+local b = false
+local n
+\stoptyping
+
+The following applies when \type {b} and \type {n} are defined this way:
+
+\starttabulate[|Tl|Tl|]
+\NC b == false \NC true  \NC \NR
+\NC n == false \NC false \NC \NR
+\NC n == nil   \NC true  \NC \NR
+\NC b == nil   \NC false \NC \NR
+\NC b == n     \NC false \NC \NR
+\NC n == nil   \NC true  \NC \NR
+\stoptabulate
+
+Often a test looks like:
+
+\starttyping
+if somevar then
+    ...
+else
+    ...
+end
+\stoptyping
+
+In this case we enter the else branch when \type {somevar} is either \type {nil}
+or \type {false}. It also means that by looking at the code we cannot beforehand
+conclude that \type {somevar} equals \type {true} or something else. If you want
+to really distinguish between the two cases you can be more explicit:
+
+\starttyping
+if somevar == nil then
+    ...
+elseif somevar == false then
+    ...
+else
+    ...
+end
+\stoptyping
+
+or
+
+\starttyping
+if somevar == true then
+    ...
+else
+    ...
+end
+\stoptyping
+
+but such an explicit test is seldom needed.
+
+There are a few more data types: tables and functions. Tables are very important
+and you can recognize them by the same curly braces that make \TEX\ famous:
+
+\starttyping
+local t = { 1, 2, 3 }
+local u = { a = 4, b = 9, c = 16 }
+local v = { [1] = "a", [3] = "2", [4] = false }
+local w = { 1, 2, 3, a = 4, b = 9, c = 16 }
+\stoptyping
+
+The \type {t} is an indexed table and \type {u} a hashed table. Because the
+second slot is empty, table \type {v} is partially indexed (slot 1) and partially
+hashed (the others). There is a gray area there, for instance, what happens when
+you nil a slot in an indexed table? In practice you will not run into problems as
+you will either use a hashed table, or an indexed table (with no holes), so table
+\type {w} is not uncommon.
+
+We mentioned that strings are in fact shared (hashed) but that an assignment of a
+string to a variable makes that variable behave like a constant. Contrary to
+that, when you assign a table, and then copy that variable, both variables can be
+used to change the table. Take this:
+
+\starttyping
+local t = { 1, 2, 3 }
+local u = t
+\stoptyping
+
+We can change the content of the table as follows:
+
+\starttyping
+t[1], t[3] = t[3], t[1]
+\stoptyping
+
+Here we swap two cells. This is an example of a parallel assigment. However, the
+following does the same:
+
+\starttyping
+t[1], t[3] = u[3], u[1]
+\stoptyping
+
+After this, both \type {t} and \type {u} still share the same table. This kind of
+behaviour is quite natural. Keep in mind that expressions are evaluated first, so
+
+\starttyping
+t[#t+1], t[#t+1] = 23, 45
+\stoptyping
+
+Makes no sense, as the values end up in the same slot. There is no gain in speed
+so using parallel assignments is mostly a convenience feature.
+
+There are a few specialized data types in \LUA, like \type {coroutines} (built
+in), \type {file} (when opened), \type {lpeg} (only when this library is linked
+in or loaded). These are called \quote {userdata} objects and in \LUATEX\ we have
+more userdata objects as we will see in later chapters. Of them nodes are the
+most noticeable: they are the core data type of the \TEX\ machinery. Other
+libraries, like \type {math} and \type {bit32} are just collections of functions
+operating on numbers.
+
+Functions look like this:
+
+\starttyping
+function sum(a,b)
+  print(a, b, a + b)
+end
+\stoptyping
+
+or this:
+
+\starttyping
+function sum(a,b)
+  return a + b
+end
+\stoptyping
+
+There can be many arguments of all kind of types and there can be multiple return
+values. A function is a real type, so you can say:
+
+\starttyping
+local f = function(s) print("the value is: " .. s) end
+\stoptyping
+
+In all these examples we defined variables as \type {local}. This is a good
+practice and avoids clashes. Now watch the following:
+
+\starttyping
+local n = 1
+
+function sum(a,b)
+  n = n + 1
+  return a + b
+end
+
+function report()
+  print("number of summations: " .. n)
+end
+\stoptyping
+
+Here the variable \type {n} is visible after its definition and accessible for
+the two global functions. Actually the variable is visible to all the code
+following, unless of course we define a new variable with the same name. We can
+hide \type {n} as follows:
+
+\starttyping
+do
+  local n = 1
+
+  sum = function(a,b)
+    n = n + 1
+    return a + b
+  end
+
+  report = function()
+    print("number of summations: " .. n)
+  end
+end
+\stoptyping
+
+This example also shows another way of defining the function: by assignment.
+
+The \typ {do ... end} creates a so called closure. There are many places where
+such closures are created, for instance in function bodies or branches like \typ
+{if ... then ... else}. This means that in the following snippet, variable \type
+{b} is not seen after the end:
+
+\starttyping
+if a > 10 then
+  local b = a + 10
+  print(b*b)
+end
+\stoptyping
+
+When you process a blob of \LUA\ code in \TEX\ (using \type {\directlua} or \type
+{\latelua}) it happens in a closure with an implied \typ {do ... end}. So, \type
+{local} defined variables are really local.
+
+\stopsection
+
+\startsection[title=\TEX's data types]
+
+We mentioned \type {numbers}. At the \TEX\ end we have counters as well as
+dimensions. Both are numbers but dimensions are specified differently
+
+\starttyping
+local n = tex.count[0]
+local m = tex.dimen.lineheight
+local o = tex.sp("10.3pt") -- sp or 'scaled point' is the smallest unit
+\stoptyping
+
+The unit of dimension is \quote {scaled point} and this is a pretty small unit:
+10 points equals to 655360 such units.
+
+Another accessible data type is tokens. They are automatically converted to
+strings and vice versa.
+
+\starttyping
+tex.toks[0] = "message"
+print(tex.toks[0])
+\stoptyping
+
+Be aware of the fact that the tokens are letters so the following will come out
+as text and not issue a message:
+
+\starttyping
+tex.toks[0] = "\message{just text}"
+print(tex.toks[0])
+\stoptyping
+
+\stopsection
+
+\startsection[title=Control structures]
+
+\index{loops}
+
+Loops are not much different from other languages: we have \typ {for ... do},
+\typ {while ... do} and \typ {repeat ... until}. We start with the simplest case:
+
+\starttyping
+for index=1,10 do
+  print(index)
+end
+\stoptyping
+
+You can specify a step and go downward as well:
+
+\starttyping
+for index=22,2,-2 do
+  print(index)
+end
+\stoptyping
+
+Indexed tables can be traversed this way:
+
+\starttyping
+for index=1,#list do
+  print(index, list[index])
+end
+\stoptyping
+
+Hashed tables on the other hand are dealt with as follows:
+
+\starttyping
+for key, value in next, list do
+  print(key, value)
+end
+\stoptyping
+
+Here \type {next} is a built in function. There is more to say about this
+mechanism but the average user will use only this variant. Slightly less
+efficient is the following, more readable variant:
+
+\starttyping
+for key, value in pairs(list) do
+  print(key, value)
+end
+\stoptyping
+
+and for an indexed table:
+
+\starttyping
+for index, value in ipairs(list) do
+  print(index, value)
+end
+\stoptyping
+
+The function call to \type {pairs(list)} returns \typ {next, list} so there is an
+(often neglectable) extra overhead of one function call.
+
+The other two loop variants, \type {while} and \type {repeat}, are similar.
+
+\starttyping
+i = 0
+while i < 10  do
+  i = i + 1
+  print(i)
+end
+\stoptyping
+
+This can also be written as:
+
+\starttyping
+i = 0
+repeat
+  i = i + 1
+  print(i)
+until i = 10
+\stoptyping
+
+Or:
+
+\starttyping
+i = 0
+while true do
+  i = i + 1
+  print(i)
+  if i = 10 then
+    break
+  end
+end
+\stoptyping
+\stopsection
+
+Of course you can use more complex expressions in such constructs.
+
+\startsection[title=Conditions]
+
+\index{expressions}
+
+Conditions have the following form:
+
+\starttyping
+if a == b or c > d or e then
+  ...
+elseif f == g then
+  ...
+else
+  ...
+end
+\stoptyping
+
+Watch the double \type {==}. The complement of this is \type {~=}. Precedence is
+similar to other languages. In practice, as strings are hashed. Tests like
+
+\starttyping
+if key == "first" then
+  ...
+end
+\stoptyping
+
+and
+
+\starttyping
+if n == 1 then
+  ...
+end
+\stoptyping
+
+are equally efficient. There is really no need to use numbers to identify states
+instead of more verbose strings.
+
+\stopsection
+
+\startsection[title=Namespaces]
+
+\index{namespaces}
+
+Functionality can be grouped in libraries. There are a few default libraries,
+like \type {string}, \type {table}, \type {lpeg}, \type {math}, \type {io} and
+\type {os} and \LUATEX\ adds some more, like \type {node}, \type {tex} and \type
+{texio}.
+
+A library is in fact nothing more than a bunch of functionality organized using a
+table, where the table provides a namespace as well as place to store public
+variables. Of course there can be local (hidden) variables used in defining
+functions.
+
+\starttyping
+do
+  mylib = { }
+
+  local n = 1
+
+  function mylib.sum(a,b)
+    n = n + 1
+    return a + b
+  end
+
+  function mylib.report()
+    print("number of summations: " .. n)
+  end
+end
+\stoptyping
+
+The defined function can be called like:
+
+\starttyping
+mylib.report()
+\stoptyping
+
+You can also create a shortcut, This speeds up the process because there are less
+lookups then. In the following code multiple calls take place:
+
+\starttyping
+local sum = mylib.sum
+
+for i=1,10 do
+  for j=1,10 do
+    print(i, j, sum(i,j))
+  end
+end
+
+mylib.report()
+\stoptyping
+
+As \LUA\ is pretty fast you should not overestimate the speedup, especially not
+when a function is called seldom. There is an important side effect here: in the
+case of:
+
+\starttyping
+  print(i, j, sum(i,j))
+\stoptyping
+
+the meaning of \type {sum} is frozen. But in the case of
+
+\starttyping
+  print(i, j, mylib.sum(i,j))
+\stoptyping
+
+The current meaning is taken, that is: each time the interpreter will access
+\type {mylib} and get the current meaning of \type {sum}. And there can be a good
+reason for this, for instance when the meaning is adapted to different
+situations.
+
+In \CONTEXT\ we have quite some code organized this way. Although much is exposed
+(if only because it is used all over the place) you should be careful in using
+functions (and data) that are still experimental. There are a couple of general
+libraries and some extend the core \LUA\ libraries. You might want to take a look
+at the files in the distribution that start with \type {l-}, like \type
+{l-table.lua}. These files are preloaded.\footnote {In fact, if you write scripts
+that need their functionality, you can use \type {mtxrun} to process the script,
+as \type {mtxrun} has the core libraries preloaded as well.} For instance, if you
+want to inspect a table, you can say:
+
+\starttyping
+local t = { "aap", "noot", "mies" }
+table.print(t)
+\stoptyping
+
+You can get an overview of what is implemented by running the following command:
+
+\starttyping
+context s-tra-02 --mode=tablet
+\stoptyping
+
+{\em todo: add nice synonym for this module and also add helpinfo at the to so
+that we can do \type {context --styles}}
+
+\stopsection
+
+\startsection[title=Comment]
+
+\index{comment}
+
+You can add comments to your \LUA\ code. There are basically two methods: one
+liners and multi line comments.
+
+\starttyping
+local option = "test" -- use this option with care
+
+local method = "unknown" --[[comments can be very long and when entered
+                             this way they and span multiple lines]]
+\stoptyping
+
+The so called long comments look like long strings preceded by \type {--} and
+there can be more complex boundary sequences.
+
+\stopsection
+
+\startsection[title=Pitfalls]
+
+Sometimes \type {nil} can bite you, especially in tables, as they have a dual nature:
+indexed as well as hashed.
+
+\startbuffer
+\startluacode
+local n1 = # { nil, 1, 2, nil }      -- 3
+local n2 = # { nil, nil, 1, 2, nil } -- 0
+
+context("n1 = %s and n2 = %s",n1,n2)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+results in: \getbuffer
+
+So, you cannot really depend on the length operator here. On the other hand, with:
+
+\startbuffer
+\startluacode
+local function check(...)
+    return select("#",...)
+end
+
+local n1 = check ( nil, 1, 2, nil )      -- 4
+local n2 = check ( nil, nil, 1, 2, nil ) -- 5
+
+context("n1 = %s and n2 = %s",n1,n2)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+we get: \getbuffer, so the \type {select} is quite useable. However, that function also
+has its specialities. The following example needs some close reading:
+
+\startbuffer
+\startluacode
+local function filter(n,...)
+    return select(n,...)
+end
+
+local v1 = { filter ( 1, 1, 2, 3 ) }
+local v2 = { filter ( 2, 1, 2, 3 ) }
+local v3 = { filter ( 3, 1, 2, 3 ) }
+
+context("v1 = %+t and v2 = %+t and v3 = %+t",v1,v2,v3)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We collect the result in a table and show the concatination:
+
+\getbuffer
+
+So, what you effectively get is the whole list starting with the given offset.
+
+\startbuffer
+\startluacode
+local function filter(n,...)
+    return (select(n,...))
+end
+
+local v1 = { filter ( 1, 1, 2, 3 ) }
+local v2 = { filter ( 2, 1, 2, 3 ) }
+local v3 = { filter ( 3, 1, 2, 3 ) }
+
+context("v1 = %+t and v2 = %+t and v3 = %+t",v1,v2,v3)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Now we get: \getbuffer. The extra \type {()} around the result makes sure that
+we only get one return value.
+
+Of course the same effect can be achieved as follows:
+
+\starttyping
+local function filter(n,...)
+    return select(n,...)
+end
+
+local v1 = filter ( 1, 1, 2, 3 )
+local v2 = filter ( 2, 1, 2, 3 )
+local v3 = filter ( 3, 1, 2, 3 )
+
+context("v1 = %s and v2 = %s and v3 = %s",v1,v2,v3)
+\stoptyping
+
+\stopsection
+
+\startsection[title={A few suggestions}]
+
+You can wrap all kind of functionality in functions but sometimes it makes no
+sense to add the overhead of a call as the same can be done with hardly any code.
+
+If you want a slice of a table, you can copy the range needed to a new table. A
+simple version with no bounds checking is:
+
+\starttyping
+local new = { } for i=a,b do new[#new+1] = old[i] end
+\stoptyping
+
+Another, much faster, variant is the following.
+
+\starttyping
+local new = { unpack(old,a,b) }
+\stoptyping
+
+You can use this variant for slices that are not extremely large. The function
+\type {table.sub} is an equivalent:
+
+\starttyping
+local new = table.sub(old,a,b)
+\stoptyping
+
+An indexed table is empty when its size equals zero:
+
+\starttyping
+if #indexed == 0 then ... else ... end
+\stoptyping
+
+Sometimes this is better:
+
+\starttyping
+if indexed and #indexed == 0 then ... else ... end
+\stoptyping
+
+So how do we test if a hashed table is empty? We can use the
+\type {next} function as in:
+
+\starttyping
+if hashed and next(indexed) then ... else ... end
+\stoptyping
+
+Say that we have the following table:
+
+\starttyping
+local t = { a=1, b=2, c=3 }
+\stoptyping
+
+The call \type {next(t)} returns the first key and value:
+
+\starttyping
+local k, v = next(t)   -- "a", 1
+\stoptyping
+
+The second argument to \type {next} can be a key in which case the
+following key and value in the hash table is returned. The result
+is not predictable as a hash is unordered. The generic for loop
+uses this to loop over a hashed table:
+
+\starttyping
+for k, v in next, t do
+    ...
+end
+\stoptyping
+
+Anyway, when \type {next(t)} returns zero you can be sure that the table is
+empty. This is how you can test for exactly one entry:
+
+\starttyping
+if t and not next(t,next(t)) then ... else ... end
+\stoptyping
+
+Here it starts making sense to wrap it into a function.
+
+\starttyping
+function table.has_one_entry(t)
+    t and not next(t,next(t))
+end
+\stoptyping
+
+On the other hand, this is not that usefull, unless you can spent the runtime on
+it:
+
+\starttyping
+function table.is_empty(t)
+    return not t or not next(t)
+end
+\stoptyping
+
+\stopsection
+
+\startsection[title=Interfacing]
+
+We have already seen that you can embed \LUA\ code using commands like:
+
+\starttyping
+\startluacode
+    print("this works")
+\stopluacode
+\stoptyping
+
+This command should not be confused with:
+
+\starttyping
+\startlua
+    print("this works")
+\stoplua
+\stoptyping
+
+The first variant has its own catcode regime which means that tokens between the start
+and stop command are treated as \LUA\ tokens, with the exception of \TEX\ commands. The
+second variant operates under the regular \TEX\ catcode regime.
+
+Their short variants are \type {\ctxluacode} and \type {\ctxlua} as in:
+
+\starttyping
+\ctxluacode{print("this works")}
+\ctxlua{print("this works")}
+\stoptyping
+
+In practice you will probably use \type {\startluacode} when using or defining % \stopluacode
+a blob of \LUA\ and \type {\ctxlua} for inline code. Keep in mind that the
+longer versions need more initialization and have more overhead.
+
+There are some more commands. For instance \type {\ctxcommand} can be used as
+an efficient way to access functions in the \type {commands} namespace. The
+following two calls are equivalent:
+
+\starttyping
+\ctxlua    {commands.thisorthat("...")}
+\ctxcommand         {thisorthat("...")}
+\stoptyping
+
+There are a few shortcuts to the \type {context} namespace. Their use can best be
+seen from their meaning:
+
+\starttyping
+\cldprocessfile#1{\directlua{context.runfile("#1")}}
+\cldloadfile   #1{\directlua{context.loadfile("#1")}}
+\cldcontext    #1{\directlua{context(#1)}}
+\cldcommand    #1{\directlua{context.#1}}
+\stoptyping
+
+The \type {\directlua{}} command can also be implemented using the token parser
+and \LUA\ itself. A variant is therefore \type {\luascript{}} which can be
+considered an alias but with a bit different error reporting. A variant on this
+is the \type {\luathread {name} {code}} command. Here is an example of their
+usage:
+
+\startbuffer
+\luascript        {        context("foo 1:") context(i) } \par
+\luathread {test} { i = 10 context("bar 1:") context(i) } \par
+\luathread {test} {        context("bar 2:") context(i) } \par
+\luathread {test} {} % resets
+\luathread {test} {        context("bar 3:") context(i) } \par
+\luascript        {        context("foo 2:") context(i) } \par
+\stopbuffer
+
+\typebuffer
+
+These commands result in:
+
+\startpacked \getbuffer \stoppacked
+
+% \testfeatureonce{100000}{\directlua        {local a = 10 local a = 10 local a = 10}} % 0.53s
+% \testfeatureonce{100000}{\luascript        {local a = 10 local a = 10 local a = 10}} % 0.62s
+% \testfeatureonce{100000}{\luathread {test} {local a = 10 local a = 10 local a = 10}} % 0.79s
+
+The variable \type {i} is local to the thread (which is not really a thread in
+\LUA\ but more a named piece of code that provides an environment which is shared
+over the calls with the same name. You will probably never need these.
+
+Each time a call out to \LUA\ happens the argument eventually gets parsed, converted
+into tokens, then back into a string, compiled to bytecode and executed. The next
+example code shows a mechanism that avoids this:
+
+\starttyping
+\startctxfunction MyFunctionA
+    context(" A1 ")
+\stopctxfunction
+
+\startctxfunctiondefinition MyFunctionB
+    context(" B2 ")
+\stopctxfunctiondefinition
+\stoptyping
+
+The first command associates a name with some \LUA\ code and that code can be
+executed using:
+
+\starttyping
+\ctxfunction{MyFunctionA}
+\stoptyping
+
+The second definition creates a command, so there we do:
+
+\starttyping
+\MyFunctionB
+\stoptyping
+
+There are some more helpers but for use in document sources they make less sense. You
+can always browse the source code for examples.

+
+Normally it makes most sense to use the English version of \CONTEXT. The
+advantage is that you can use English keywords, as in:
+
+\starttyping
+context.framed( {
+    frame = "on",
+  },
+  "some text"
+)
+\stoptyping
+
+If you use the Dutch interface it looks like this:
+
+\starttyping
+context.omlijnd( {
+    kader = "aan",
+  },
+  "wat tekst"
+)
+\stoptyping
+
+A rather neutral way is:
+
+\starttyping
+context.framed( {
+    frame = interfaces.variables.on,
+  },
+  "some text"
+)
+\stoptyping
+
+But as said, normally you will use the English user interface so you can forget
+about these matters. However, in the \CONTEXT\ core code you will often see the
+variables being used this way because there we need to support all user
+interfaces.
+
+\stopsection
+
+\startsection[title=Modes]
+
+\index{modes}
+\index{systemmodes}
+\index{constants}
+
+Context carries a concept of modes. You can use modes to create conditional
+sections in your style (and|/|or content). You can control modes in your styles
+or you can set them at the command line or in job control files. When a mode test
+has to be done at processing time, then you need constructs like the following:
+
+\starttyping
+context.doifmodeelse( "screen",
+  function()
+      ... -- mode == screen
+  end,
+  function()
+      ... -- mode ~= screen
+  end
+)
+\stoptyping
+
+However, often a mode does not change during a run, and then we can use the
+following method:
+
+\starttyping
+if tex.modes["screen"] then
+  ...
+else
+  ...
+end
+\stoptyping
+
+Watch how the \type {modes} table lives in the \type {tex} namespace. We also
+have \type {systemmodes}. At the \TEX\ end these are mode names preceded by a
+\type {*}, so the following code is similar:
+
+\starttyping
+if tex.modes["*mymode"] then
+  -- this is the same
+elseif tex.systemmodes["mymode"] then
+  -- test as this
+else
+  -- but not this
+end
+\stoptyping
+
+Inside \CONTEXT\ we also have so called constants, and again these can be
+consulted at the \LUA\ end:
+
+\starttyping
+if tex.constants["someconstant'] then
+  ...
+else
+  ...
+end
+\stoptyping
+
+But you will hardly need these and, as they are often not public, their
+meaning can change, unless of course they {\em are} documented as public.
+
+\stopsection
+
+\startsection[title={Token lists}]
+
+\index{tokens}
+
+There is normally no need to mess around with nodes and tokens at the \LUA\ end
+yourself. However, if you do, then you might want to flush them as well. Say that
+at the \TEX\ end we have said:
+
+\startbuffer
+\toks0 = {Don't get \inframed{framed}!}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Then at the \LUA\ end you can say:
+
+\startbuffer
+context(tex.toks[0])
+\stopbuffer
+
+\typebuffer
+
+and get: \ctxluabuffer\ In fact, token registers are exposed as strings so here,
+register zero has type \type {string} and is treated as such.
+
+\startbuffer
+context("< %s >",tex.toks[0])
+\stopbuffer
+
+\typebuffer
+
+This gives: \ctxluabuffer. But beware, if you go the reverse way, you don't get
+what you might expect:
+
+\startbuffer
+tex.toks[0] = [[\framed{oeps}]]
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+If we now say \type{\the\toks0} we will get {\tttf \the\toks0} as
+all tokens are considered to be letters.
+
+\stopsection
+
+\startsection[title={Node lists}]
+
+\index{nodes}
+
+If you're not deep into \TEX\ you will never feel the need to manipulate node
+lists yourself, but you might want to flush boxes. As an example we put something
+in box zero (one of the scratch boxes).
+
+\startbuffer
+\setbox0 = \hbox{Don't get \inframed{framed}!}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+At the \TEX\ end you can flush this box (\type {\box0}) or take a copy
+(\type{\copy0}). At the \LUA\ end you would do:
+
+\starttyping
+context.copy()
+context.direct(0)
+\stoptyping
+
+or:
+
+\starttyping
+context.copy(false,0)
+\stoptyping
+
+but this works as well:
+
+\startbuffer
+context(node.copy_list(tex.box[0]))
+\stopbuffer
+
+\typebuffer
+
+So we get: \ctxluabuffer\ If you do:
+
+\starttyping
+context(tex.box[0])
+\stoptyping
+
+you also need to make sure that the box is freed but let's not go into those
+details now.
+
+Here is an example if messing around with node lists that get seen before a
+paragraph gets broken into lines, i.e.\ when hyphenation, font manipulation etc
+take place. First we define some colors:
+
+\startbuffer
+\definecolor[mynesting:0][r=.6]
+\definecolor[mynesting:1][g=.6]
+\definecolor[mynesting:2][r=.6,g=.6]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Next we define a function that colors nodes in such a way that we can see the
+different processing stages.
+
+\startbuffer
+\startluacode
+local enabled  = false
+local count    = 0
+local setcolor = nodes.tracers.colors.set
+
+function userdata.processmystuff(head)
+    if enabled then
+        local color = "mynesting:" .. (count % 3)
+     -- for n in node.traverse(head) do
+        for n in node.traverse_id(nodes.nodecodes.glyph,head) do
+            setcolor(n,color)
+        end
+        count = count + 1
+        return head, true
+    end
+    return head, false
+end
+
+function userdata.enablemystuff()
+    enabled = true
+end
+
+function userdata.disablemystuff()
+    enabled = false
+end
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We hook this function into the normalizers category of the processor callbacks:
+
+\startbuffer
+\startluacode
+nodes.tasks.appendaction("processors", "normalizers", "userdata.processmystuff")
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We now can enable this mechanism and show an example:
+
+\startbuffer
+\startbuffer
+Node lists are processed \hbox {nested from \hbox{inside} out} which is not
+what you might expect. But, \hbox{coloring} does not \hbox {happen} really
+nested here, more \hbox {in} \hbox {the} \hbox {order} \hbox {of} \hbox
+{processing}.
+\stopbuffer
+
+\ctxlua{userdata.enablemystuff()}
+\par \getbuffer \par
+\ctxlua{userdata.disablemystuff()}
+\stopbuffer
+
+\typebuffer
+
+The \type {\par} is needed because otherwise the processing is already disabled
+before the paragraph gets seen by \TEX.
+
+\blank \getbuffer \blank
+
+\startbuffer
+\startluacode
+nodes.tasks.disableaction("processors", "userdata.processmystuff")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Instead of using an boolean to control the state, we can also do this:
+
+\starttyping
+\startluacode
+local count    = 0
+local setcolor = nodes.tracers.colors.set
+
+function userdata.processmystuff(head)
+    count = count + 1
+    local color = "mynesting:" .. (count % 3)
+    for n in node.traverse_id(nodes.nodecodes.glyph,head) do
+        setcolor(n,color)
+    end
+    return head, true
+end
+
+nodes.tasks.appendaction("processors", "after", "userdata.processmystuff")
+\stopluacode
+\stoptyping
+
+\startbuffer
+\startluacode
+nodes.tasks.disableaction("processors", "userdata.processmystuff")
+\stopluacode
+\stopbuffer
+
+Disabling now happens with:
+
+\typebuffer \getbuffer
+
+As you might want to control these things in more details, a simple helper
+mechanism was made: markers. The following example code shows the way:
+
+\startbuffer
+\definemarker[mymarker]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Again we define some colors:
+
+\startbuffer
+\definecolor[mymarker:1][r=.6]
+\definecolor[mymarker:2][g=.6]
+\definecolor[mymarker:3][r=.6,g=.6]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \LUA\ code like similar to the code presented before:
+
+\startbuffer
+\startluacode
+local setcolor    = nodes.tracers.colors.setlist
+local getmarker   = nodes.markers.get
+local hlist_code  = nodes.codes.hlist
+local traverse_id = node.traverse_id
+
+function userdata.processmystuff(head)
+    for n in traverse_id(hlist_code,head) do
+        local m = getmarker(n,"mymarker")
+        if m then
+            setcolor(n.list,"mymarker:" .. m)
+        end
+    end
+    return head, true
+end
+
+nodes.tasks.appendaction("processors", "after", "userdata.processmystuff")
+nodes.tasks.disableaction("processors", "userdata.processmystuff")
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This time we disabled the processor (if only because in this document we don't
+want the overhead.
+
+\startbuffer
+\startluacode
+nodes.tasks.enableaction("processors", "userdata.processmystuff")
+\stopluacode
+
+Node lists are processed \hbox \boxmarker{mymarker}{1} {nested from \hbox{inside}
+out} which is not what you might expect. But, \hbox {coloring} does not \hbox
+{happen} really nested here, more \hbox {in} \hbox \boxmarker{mymarker}{2} {the}
+\hbox {order} \hbox {of} \hbox \boxmarker{mymarker}{3} {processing}.
+
+\startluacode
+nodes.tasks.disableaction("processors", "userdata.processmystuff")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+The result looks familiar:
+
+\getbuffer
+
+% We don't want the burden of this demo to cary on:
+
+% {\em If there's enough interest I will expand this section with some basic
+% information on what nodes are.}

+\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. Currently a \PDF\ backend is
+supported as well as an \XML\ export. \footnote {This chapter is derived from an
+article on these matters. You can find nore information in \type {hybrid.pdf}.}
+
+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. Therefore the construction of \PDF\ data structures
+and resources is rather controlled and has to be done via the official helper
+macros.
+
+\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.
+
+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.
+
+\stopsection
+
+\startsection [title={Data types}]
+
+There are several datatypes in \PDF\ and we support all of them one way or the
+other.
+
+\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
+
+The \LUATEX\ manual mentions primitives like \type {\pdfobj}, \type {\pdfannot},
+\type {\pdfcatalog}, etc. However, in \MKIV\ no such primitives are used. You can
+still use many of them but those that push data into document or page related
+resources 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 = lpdf.immediateobject(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

+\stopsection
+
+\startsection[title={Managing objects}]
+
+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
+
+A delayed object is created with:
+
+\starttyping
+local ref = pdf.delayedobject(data)
+\stoptyping
+
+The data will be flushed later using the object number that is returned (\type
+{ref}). When you expect that many object with the same content are used, you can
+use:
+
+\starttyping
+local obj = lpdf.shareobject(data)
+local ref = lpdf.shareobjectreference(data)
+\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. Only use this when it's really needed as it might consume more
+memory and needs more processing time.
+
+\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. Because
+third party modules (like tikz) also can add resources we provide some macros
+that makes sure that no interference takes place:
+
+\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 but when code is shared with other macro packages the macro
+interface makes more sense. The names of the \LUA\ functions are similar, like:
+
+\starttyping
+lpdf.addtoinfo(key,anything_valid_pdf)
+\stoptyping
+
+Currently we expose a  bit 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
+
+\stopsection
+
+\startsection [title={Annotations}]
+
+You can use the \LUA\ functions that relate to annotations etc.\ but normally you
+will use the regular \CONTEXT\ user interface. You can look into some of the
+\type {lpdf-*} modules to see how special annotations can be dealt with.
+
+\stopsection
+
+\startsection [title={Tracing}]
+
+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. When you write
+code that generates \PDF, it also helps to look in the \PDF\ file so see if
+things are done right. In that case you need to disable compression:
+
+\starttyping
+\nopdfcompression
+\stoptyping
+
+\stopsection
+
+\startsection[title={Analyzing}]
+
+The \type {epdf} library that comes with \LUATEX\ offers a userdata interface to
+\PDF\ files. On top of that \CONTEXT\ provides a more \LUA-ish access, using
+tables. You can open a \PDF\ file with:
+
+\starttyping
+local mypdf = lpdf.epdf.load(filename)
+\stoptyping
+
+When opening is successful, you have access to a couple of tables:
+
+\starttyping
+\NC \type{pages}         \NC indexed \NC \NR
+\NC \type{destinations}  \NC hashed  \NC \NR
+\NC \type{javascripts}   \NC hashed  \NC \NR
+\NC \type{widgets}       \NC hashed  \NC \NR
+\NC \type{embeddedfiles} \NC hashed  \NC \NR
+\NC \type{layers}        \NC indexed \NC \NR
+\stoptyping
+
+These provide efficient access to some data that otherwise would take a bit of
+code to deal with. Another top level table is the for \PDF\ characteristic \type
+{Catalog}. Watch the capitalization: as with other native \PDF\ data structures,
+keys are case sensitive and match the standard.
+
+Here is an example of usage:
+
+\starttyping
+local MyDocument = lpdf.epdf.load("somefile.pdf")
+
+context.starttext()
+
+  local pages    = MyDocument.pages
+  local nofpages = pages.n
+
+  context.starttabulate { "|c|c|c|" }
+
+    context.NC() context("page")
+    context.NC() context("width")
+    context.NC() context("height") context.NR()
+
+    for i=1, nofpages do
+      local page = pages[i]
+      local bbox = page.CropBox or page.MediaBox
+      context.NC() context(i)
+      context.NC() context(bbox[4]-bbox[2])
+      context.NC() context(bbox[3]-bbox[1]) context.NR()
+    end
+
+  context.stoptabulate()
+
+context.stoptext()
+\stoptyping

+
+The \LUATEX\ engine provides the usual basic \TEX\ functionality plus a bit more.
+It is a deliberate choice not to extend the core engine too much. Instead all
+relevant processes can be overloaded by new functionality written in \LUA. In
+\CONTEXT\ callbacks are wrapped in a protective layer: on the one hand there is
+extra functionality (usually interfaced through macros) and on the other hand
+users can pop in their own handlers using hooks. Of course a plugged in function
+has to do the right thing and not mess up the data structures. In this chapter
+the layer on top of callbacks is described.
+
+\stopsection
+
+\startsection [title={Actions}]
+
+\index {nodelists}
+
+Nearly all callbacks in \LUATEX\ are used in \CONTEXT. 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.
+
+% \ctxlua{callbacks.table()} % \ctxlua{callbacks.report()}
+\ctxcommand{showcallbacks()}
+
+Eventually all callbacks will be used so don't rely on undefined callbacks not
+being protected. 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.
+
+All callbacks related to file handling, font definition and housekeeping are
+frozen and cannot be overloaded. A reason for this are that we need some kind of
+protection against misuse. Another reason is that we operate in a well defined
+environment, the so called \TEX\ directory structure, and we don't want to mess
+with that. And of course, the overloading permits \CONTEXT\ to provide extensions
+beyond regular engine functionality.
+
+So as a fact we only open up some of the node list related callbacks and these
+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
+\TL
+\NC \type{processors}   \NC \type{head, ...} \NC \type{head, done} \NC \NR
+\NC \type{finalizers}   \NC \type{head, ...} \NC \type{head, done} \NC \NR
+\NC \type{shipouts}     \NC \type{head}      \NC \type{head, done} \NC \NR

+\startsection [title={Tasks}]
+
+\index {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.
+
+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")}
+
+{\em Both the parbuilders and pagebuilder tasks are unofficial and not yet meant
+for users.}
+
+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.
+

+Building paragraphs and pages is implemented differently and has no user hooks.

+\startchapter[title={The \LUA\ interface code}]
+
+\startsection[title={Introduction}]
+
+There is a lot of \LUA\ code in \MKIV. Much is not exposed and a lot of what is
+exposed is not meant to be used directly at the \LUA\ end. But there is also
+functionality and data that can be accessed without side effects.
+
+In the following sections a subset of the built in functionality is discussed.
+There are often more functions alongside those presented but they might change or
+disappear. So, if you use undocumented features, be sure to tag them somehow in
+your source code so that you can check them out when there is an update. Best
+would be to have more functionality defined local so that it is sort of hidden
+but that would be unpractical as for instance functions are often used in other
+modules and or have to be available at the \TEX\ end.
+
+It might be tempting to add your own functions to namespaces created by \CONTEXT\
+or maybe overload some existing ones. Don't do this. First of all, there is no
+guarantee that your code will not interfere, nor that it overloads future
+functionality. Just use your own namespace. Also, future versions of \CONTEXT\
+might have a couple of protection mechanisms built in. Without doubt the
+following sections will be extended as soon as interfaces become more stable.
+
+\stopsection
+
+\startsection[title={Characters}]
+
+% not discussed:
+%
+% characters.filters.utf.addgrapheme()
+% characters.filters.utf.collapse()
+% characters.getrange()
+% characters.bidi[]
+% tex.uprint()
+% utf.string()
+% characters.flush()
+
+There are quite some data tables defined but the largest is the character
+database. You can consult this table any time you want but you're not supposed to
+add or change its content if only because changes will be overwritten when you
+update \CONTEXT. Future versions may carry more information. The table can be
+accessed using an unicode number. A relative simple entry looks as follows:
+
+\ShowLuaExampleTableHex{characters.data[0x00C1]}
+
+Much of this is rather common information but some of it is specific for use with
+\CONTEXT. Some characters have even more information, for instance those that
+deal with mathematics:
+
+\ShowLuaExampleTableHex{characters.data[0x2190]}
+
+Not all characters have a real entry. For instance most \CJK\ characters are
+virtual and share the same data:
+
+\ShowLuaExampleTableHex{characters.data[0x3456]}
+
+You can also access the table using \UTF\ characters:
+
+\ShowLuaExampleTable{characters.data["ä"]}
+
+A more verbose string access is also supported:
+
+\ShowLuaExampleTableHex{characters.data["U+0070"]}
+
+Another (less usefull) table contains information about ranges in this character
+table. You can access this table using rather verbose names, or you can use
+collapsed lowercase variants.
+
+\ShowLuaExampleTableHex{characters.blocks["CJK Compatibility Ideographs"]}
+
+\ShowLuaExampleTableHex{characters.blocks["hebrew"]}
+
+\ShowLuaExampleTableHex{characters.blocks["combiningdiacriticalmarks"]}
+
+Some fields can be accessed using functions. This can be handy when you need that
+information for tracing purposes or overviews. There is some overhead in the
+function call, but you get some extra testing for free. You can use characters as
+well as numbers as index.
+
+\ShowLuaExampleString{characters.contextname("ä")}
+\ShowLuaExampleString{characters.adobename(228)}
+\ShowLuaExampleString{characters.description("ä")}
+
+The category is normally a two character tag, but you can also ask for a more
+verbose variant:
+
+\ShowLuaExampleString{characters.category(228)}
+\ShowLuaExampleString{characters.category(228,true)}
+
+The more verbose category tags are available in a table:
+
+\ShowLuaExampleString{characters.categorytags["lu"]}
+
+There are several fields in a character entry that help us to remap a character.
+The \type {lccode} indicates the lowercase code point and the \type {uccode} to
+the uppercase code point. The \type {shcode} refers to one or more characters
+that have a similar shape.
+
+\ShowLuaExampleString{characters.shape ("ä")}
+\ShowLuaExampleString{characters.uccode("ä")}
+\ShowLuaExampleString{characters.lccode("ä")}
+
+\ShowLuaExampleString{characters.shape (100)}
+\ShowLuaExampleString{characters.uccode(100)}
+\ShowLuaExampleString{characters.lccode(100)}
+
+You can use these function or access these fields directly in an
+entry, but we also provide a few virtual tables that avoid
+accessing the whole entry. This method is rather efficient.
+
+\ShowLuaExampleString{characters.lccodes["ä"]}
+\ShowLuaExampleString{characters.uccodes["ä"]}
+\ShowLuaExampleString{characters.shcodes["ä"]}
+\ShowLuaExampleString{characters.lcchars["ä"]}
+\ShowLuaExampleString{characters.ucchars["ä"]}
+\ShowLuaExampleString{characters.shchars["ä"]}
+
+As with other tables, you can use a number instead of an \UTF\ character. Watch
+how we get a table for multiple shape codes but a string for multiple shape
+characters.
+
+\ShowLuaExampleString{characters.lcchars[0x00C6]}
+\ShowLuaExampleString{characters.ucchars[0x00C6]}
+\ShowLuaExampleString{characters.shchars[0x00C6]}
+\ShowLuaExampleTable {characters.shcodes[0x00C6]}
+
+These codes are used when we manipulate strings. Although there
+are \type {upper} and \type {lower} functions in the \type
+{string} namespace, the following ones are the real ones to be
+used in critical situations.
+
+\ShowLuaExampleString{characters.lower("ÀÁÂÃÄÅàáâãäå")}
+\ShowLuaExampleString{characters.upper("ÀÁÂÃÄÅàáâãäå")}
+\ShowLuaExampleString{characters.shaped("ÀÁÂÃÄÅàáâãäå")}
+
+A rather special one is the following:
+
+\ShowLuaExampleString{characters.lettered("Only 123 letters + count!")}
+
+With the second argument is true, spaces are kept and collapsed. Leading and
+trailing spaces are stripped.
+
+\ShowLuaExampleString{characters.lettered("Only 123 letters + count!",true)}
+
+Access to tables can happen by number or by string, although there are some
+limitations when it gets too confusing. Take for instance the number \type {8}
+and string \type {"8"}: if we would interpret the string as number we could never
+access the entry for the character eight. However, using more verbose hexadecimal
+strings works okay. The remappers are also available as functions:
+
+\ShowLuaExampleString{characters.tonumber("a")}
+\ShowLuaExampleString{characters.fromnumber(100)}
+\ShowLuaExampleString{characters.fromnumber(0x0100)}
+\ShowLuaExampleString{characters.fromnumber("0x0100")}
+\ShowLuaExampleString{characters.fromnumber("U+0100")}
+
+In addition to the already mentioned category information you can also use a more
+direct table approach:
+
+\ShowLuaExampleString{characters.categories["ä"]}
+\ShowLuaExampleString{characters.categories[100]}
+
+In a similar fashion you can test if a given character is in a specific category.
+This can save a lot of tests.
+
+\ShowLuaExampleBoolean{characters.is_character[characters.categories[67]]}
+\ShowLuaExampleBoolean{characters.is_character[67]}
+\ShowLuaExampleBoolean{characters.is_character[characters.data[67].category]}
+\ShowLuaExampleBoolean{characters.is_letter[characters.data[67].category]}
+\ShowLuaExampleBoolean{characters.is_command[characters.data[67].category]}
+
+Another virtual table is the one that provides access to special information, for
+instance about how a composed character is made up of components.
+
+\ShowLuaExampleString{characters.specialchars["ä"]}
+\ShowLuaExampleString{characters.specialchars[100]}
+
+The outcome is often similar to output that uses the shapecode information.
+
+Although not all the code deep down in \CONTEXT\ is meant for use at the user
+level, it sometimes can eb tempting to use data and helpers that are available as
+part of the general housekeeping. The next table was used when looking into
+sorting Korean. For practical reasons we limit the table to ten entries;
+otherwise we would have ended up with hundreds of pages.

+There is a lot of code that deals with fonts but most is considered to be a black
+box. When a font is defined, its data is collected and turned into a form that
+\TEX\ likes. We keep most of that data available at the \LUA\ end so that we can
+later use it when needed. In this chapter we discuss some of the possibilities.
+More details can be found in the font manual(s) so we don't aim for completeness
+here.
+
+A font instance is identified by its id, which is a number where zero is reserved
+for the so called \type {nullfont}. The current font id can be requested by the
+following function.
+
+\ShowLuaExampleString{fonts.currentid()}
+
+The \type {fonts.current()} call returns the table with data related to the

+The math parameters are rather special and explained in the \LUATEX\ manual.
+Quite certainly you never have to touch these parameters at the \LUA\ end.
+
+En entry in the \type {characters} table describes a character if we have entries

+
+Say that you run into a glyph node and want to access the data related to that
+glyph. Given that variable \type {n} points to the node, the most verbose way of
+doing that is:
+
+\starttyping
+local g = fonts.identifiers[n.id].characters[n.char]
+\stoptyping
+
+Given the speed of \LUATEX\ this is quite fast. Another method is the following:
+
+\starttyping
+local g = fonts.characters[n.id][n.char]
+\stoptyping
+
+For some applications you might want faster access to critical
+parameters, like:
+
+\starttyping
+local quad    = fonts.quads   [n.id][n.char]
+local xheight = fonts.xheights[n.id][n.char]
+\stoptyping
+
+but that only makes sense when you don't access more than one such variable at
+the same time.
+
+Among the shared tables is the feature specification:
+
+\ShowLuaExampleTable{fonts.current().shared.features}
+
+As features are a prominent property of \OPENTYPE\ fonts, there are a few
+datatables that can be used to get their meaning.
+
+\ShowLuaExampleString{fonts.handlers.otf.tables.features['liga']}
+\ShowLuaExampleString{fonts.handlers.otf.tables.languages['nld']}
+\ShowLuaExampleString{fonts.handlers.otf.tables.scripts['arab']}
+
+There is a rather extensive font database built in but discussing its interface
+does not make much sense. Most usage happens automatically when you use the \type
+{name:} and \type {spec:} methods of defining fonts and the \type {mtx-fonts}
+script is built on top of it.
+
+\ctxlua{fonts.names.load()} % could be metatable driven
+
+\ShowLuaExampleTable{table.sortedkeys(fonts.names.data)}
+
+You can load the database (if it's not yet loaded) with:
+
+\starttyping
+names.load(reload,verbose)
+\stoptyping
+
+When the first argument is true, the database will be rebuild. The second
+arguments controls verbosity.
+
+Defining a font normally happens at the \TEX\ end but you can also do it in \LUA.
+
+\starttyping
+local id, fontdata = fonts.definers.define {
+    lookup = "file",             -- use the filename (file spec name)
+    name   = "pagella-regular",  -- in this case the filename
+    size   = 10*65535,           -- scaled points
+    global = false,              -- define the font globally
+    cs     = "MyFont",           -- associate the name \MyFont
+    method = "featureset",       -- featureset or virtual (* or @)
+    sub    = nil,                -- no subfont specifier
+    detail = "whatever",         -- the featureset (or whatever method applies)
+}
+\stoptyping
+
+In this case the \type {detail} variable defines what featureset has to be
+applied. You can define such sets at the \LUA\ end too:
+
+\starttyping
+fonts.definers.specifiers.presetcontext (
+    "whatever",
+    "default",
+    {
+        mode = "node",
+        dlig = "yes",
+    }
+)
+\stoptyping
+
+The first argument is the name of the featureset. The second argument can be an
+empty string or a reference to an existing featureset that will be taken as
+starting point. The final argument is the featureset. This can be a table or a
+string with a comma separated list of key|/|value pairs.
+
+\stopsection
+
+\startsection[title={Nodes}]
+
+Nodes are the building blocks that make a document reality. Nodes are linked into
+lists and at various moments in the typesetting process you can manipulate them.
+Deep down in \CONTEXT\ we use quite some \LUA\ magic to manipulate lists of
+nodes. Therefore it is no surprise that we have some tracing available. Take the
+following box.
+
+\startbuffer
+\setbox0\hbox{It's in \hbox{\bf all} those nodes.}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This box contains characters and glue between the words. The box is already
+constructed. There can also be kerns between characters, but of course only if
+the font provides such a feature. Let's inspect this box:
+
+\ShowLuaExampleString{nodes.toutf(tex.box[0])}
+\ShowLuaExampleString{nodes.toutf(tex.box[0].list)}
+
+This tracer returns the text and spacing and recurses into nested lists. The next
+tracer does not do this and marks non glyph nodes as \type {[-]}:
+
+\ShowLuaExampleString{nodes.listtoutf(tex.box[0])}
+\ShowLuaExampleString{nodes.listtoutf(tex.box[0].list)}
+
+A more verbose tracer is the next one. It does show a bit more detailed
+information about the glyphs nodes.
+
+\ShowLuaExampleString{nodes.tosequence(tex.box[0])}
+\ShowLuaExampleString{nodes.tosequence(tex.box[0].list)}
+
+The fourth tracer does not show that detail and collapses sequences of similar
+node types.
+
+\ShowLuaExampleString{nodes.idstostring(tex.box[0])}
+\ShowLuaExampleString{nodes.idstostring(tex.box[0].list)}
+
+The number of nodes in a list is identified with the \type {countall} function.
+Nested nodes are counted too.
+
+\ShowLuaExampleString{nodes.countall(tex.box[0])}
+\ShowLuaExampleString{nodes.countall(tex.box[0].list)}
+
+There are a lot of helpers in the \type {nodes} namespace. In fact, we map all the
+helpers provided by the engine itself under \type {nodes} too. These are described
+in the \LUATEX\ manual. There are for instance functions to check node types and
+node id's:
+
+\starttyping
+local str = node.type(1)
+local num = node.id("vlist")
+\stoptyping
+
+These are basic \LUATEX\ functions. In addition to those we also provide a few more
+helpers as well as
+mapping tables. There are two tables that map node id's to strings and backwards:
+
+\starttabulate
+\NC \type{nodes.nodecodes}    \NC regular nodes, some fo them are sort of private to the engine \NC \NR
+\NC \type{nodes.noadcodes}    \NC math nodes that later on are converted into regular nodes  \NC \NR
+\stoptabulate
+
+Nodes can have subtypes. Again we have tables that map the subtype numbers onto
+meaningfull names and reverse.
+
+\starttabulate
+\NC \type{nodes.listcodes}    \NC subtypes of \type {hlist} and \type {vlist} nodes \NC \NR
+\NC \type{nodes.kerncodes}    \NC subtypes of \type {kern} nodes \NC \NR
+\NC \type{nodes.gluecodes}    \NC subtypes of \type {glue} nodes (skips) \NC \NR
+\NC \type{nodes.glyphcodes}   \NC subtypes of \type {glyph} nodes, the subtype can change \NC \NR
+\NC \type{nodes.mathcodes}    \NC math specific subtypes \NC \NR
+\NC \type{nodes.fillcodes}    \NC these are not really subtypes but indicate the strength of the filler \NC \NR
+\NC \type{nodes.whatsitcodes} \NC subtypes of a rather large group of extension nodes \NC \NR
+\stoptabulate
+
+Some of the names of types and subtypes have underscores but you can omit them
+when you use these tables. You can use tables like this as follows:
+
+\starttyping
+local glyph_code = nodes.nodecodes.glyph
+local kern_code  = nodes.nodecodes.kern
+local glue_code  = nodes.nodecodes.glue
+
+for n in nodes.traverse(list) do
+    local id == n.id
+    if id == glyph_code then
+        ...
+    elseif id == kern_code then
+        ...
+    elseif id == glue_code then
+        ...
+    else
+        ...
+    end
+end
+\stoptyping
+
+You only need to use such temporary variables in time critical code. In spite of
+what you might think, lists are not that long and given the speed of \LUA\ (and
+successive optimizations in \LUATEX) looping over a paragraphs is rather fast.
+
+Nodes are created using \type {node.new}. If you study the \CONTEXT\ code you
+will notice that there are quite some functions in the \type {nodes.pool}
+namespace, like:
+
+\starttyping
+local g = nodes.pool.glyph(fnt,chr)
+\stoptyping
+
+Of course you need to make sure that the font id is valid and that the referred
+glyph in in the font. You can use the allocators but don't mess with the code in
+the \type {pool} namespace as this might interfere with its usage all over
+\CONTEXT.
+
+The \type {nodes} namespace provides a couple of helpers and some of them are
+similar to ones provided in the \type {node} namespace. This has practical as
+well as historic reasons. For instance some were prototypes functions that were
+later built in.
+
+\starttyping
+local head, current      = nodes.before (head, current, new)
+local head, current      = nodes.after  (head, current, new)
+local head, current      = nodes.delete (head, current)
+local head, current      = nodes.replace(head, current, new)
+local head, current, old = nodes.remove (head, current)
+\stoptyping
+
+Another category deals with attributes:
+
+\starttyping
+nodes.setattribute      (head, attribute, value)
+nodes.unsetattribute    (head, attribute)
+nodes.setunsetattribute (head, attribute, value)
+nodes.setattributes     (head, attribute, value)
+nodes.unsetattributes   (head, attribute)
+nodes.setunsetattributes(head, attribute, value)
+nodes.hasattribute      (head, attribute, value)
+\stoptyping
+
+% context(typesetters.hpack("Hello World!"))
+% context(typesetters.hpack("Hello World!",1,100*1024*10))
+
+% nodes.firstchar
+% nodes.firstcharinbox
+
+% maybe node-tst
+% tasks and so
+% number.points (to numbers)
+
+\stopsection
+
+% \startsection[title={Core}]
+%     {\em todo}
+% \stopsection
+
+\startsection[title={Resolvers}]
+
+All \IO\ is handled by functions in the \type {resolvers} namespace. Most of the
+code that you find in the \type {data-*.lua} files is of litle relevance for
+users, especially at the \LUA\ end, so we won't discuss it here in great detail.
+
+The resolver code is modelled after the \KPSE\ library that itself implements the
+\TEX\ Directory Structure in combination with a configuration file. However, we
+go a bit beyond this structure, for instance in integrating support for other
+resources that file systems. We also have our own configuration file. But
+important is that we still support a similar logic too so that regular
+configurations are dealt with.
+
+During a run \LUATEX\ needs files of a different kind: source files, font files,
+images, etc. In practice you will probably only deal with source files. The most
+fundamental function is \type {findfile}. The first argument is the filename to
+be found. A second optional argument indicates the file type.
+
+The following table relates so called formats to suffixes and variables in the
+configuration file.
+
+\startluacode
+context.starttabulate { "|lp|lp|l|" }
+context.NC() context.bold("variable")
+context.NC() context.bold("format")
+context.NC() context.bold("suffix")
+context.NC() context.NR()
+context.ML()
+for k, v in table.sortedpairs(resolvers.relations.core) do
+    local names = v.names
+    local variable = v.variable
+    local suffixes = v.suffixes
+    context.NC()
+    if variable then
+        context.type(variable)
+    end
+    context.NC()
+    if names then
+        for i=1,#names do
+            context.type(names[i])
+            context.par()
+        end
+    end
+    context.NC()
+    if suffixes then
+        context.type(table.concat(suffixes, " "))
+    end
+    context.NC()
+    context.NR()
+end
+context.stoptabulate()
+\stopluacode
+
+There are a couple of more formats but these are not that relevant in the
+perspective of \CONTEXT.
+
+When a lookup takes place, spaces are ignored and formats are normalized to
+lowercase.
+
+\ShowLuaExampleString{file.strip(resolvers.findfile("context.tex"),"tex/")}
+\ShowLuaExampleString{file.strip(resolvers.findfile("context.mkiv"),"tex/")}

+
+\startsection[title={Preprocessing}]
+
+Although this option must be used with care, it is possible to preprocess files
+before they enter \TEX. The following example shows this.
+
+\starttyping
+local function showline(str,filename,linenumber,noflines)
+    logs.simple("[lc] file: %s, line: %s of %s, length: %s",
+        file.basename(filename),linenumber,noflines,#str)
+end
+
+local function showfile(str,filename)
+    logs.simple("[fc] file: %s, length: %s",
+        file.basename(filename),#str)
+end
+
+resolvers.installinputlinehandler(showline)
+resolvers.installinputfilehandler(showfile)
+\stoptyping
+
+Preprocessors like this are rather innocent. If you want to manipulate the
+content you need to be aware of the fact that modules and such also pass your
+code, and manipulating them can give unexpected side effects. So, the following
+code will not make \CONTEXT\ happy.
+
+\starttyping
+local function foo()
+    return "bar"
+end
+
+resolvers.installinputlinehandler(foo)
+\stoptyping
+
+But, as we pass the filename, you can base your preprocessing on names.
+
+There can be multiple handlers active at the same time, and although more
+detailed control is possible, the current interface does not provide that, simply
+because having too many handlers active is asking for trouble anyway. What you
+can do, is putting your handler in front or after the built in handlers.
+
+\starttyping
+resolvers.installinputlinehandler("before",showline)
+resolvers.installinputfilehandler("after", showfile)
+\stoptyping
+
+Of course you can also preprocess files outside this mechanism, which in most
+cases might be a better idea. However, the following example code is quite
+efficient and robust.
+
+\starttyping
+local function MyHandler(str,filename)
+    if file.suffix(filename) == "veryspecial" then
+        logs.simple("preprocessing file '%s',filename)
+        return MyConverter(str)
+    else
+        return str
+    end
+end
+
+resolvers.installinputfilehandler("before",MyHandler)
+\stoptyping
+
+In this case only files that have a suffix \type {.veryspecial} will get an extra
+treatment.

+\startsection[title=Some basics]
+
+\index{processing}
+
+I assume that you have either the so called \CONTEXT\ standalone (formerly known
+as minimals) installed or \TEXLIVE. You only need \LUATEX\ and can forget about
+installing \PDFTEX\ or \XETEX, which saves you some megabytes and hassle. Now,
+from the users perspective a \CONTEXT\ run goes like:
+
+\starttyping
+context yourfile
+\stoptyping
+
+and by default a file with suffix \type {tex}, \type {mkvi} or \type {mkvi} will
+be processed. There are however a few other options:
+
+\starttyping
+context yourfile.xml
+context yourfile.rlx --forcexml
+context yourfile.lua
+context yourfile.pqr --forcelua
+context yourfile.cld
+context yourfile.xyz --forcecld
+context yourfile.mp
+context yourfile.xyz --forcemp
+\stoptyping
+
+When processing a \LUA\ file the given file is loaded and just processed. This
+options will seldom be used as it is way more efficient to let \type {mtxrun}
+process that file. However, the last two variants are what we will discuss here.
+The suffix \type {cld} is a shortcut for \CONTEXT\ \LUA\ Document.
+
+A simple \type {cld} file looks like this:
+
+\starttyping
+context.starttext()
+context.chapter("Hello There!")
+context.stoptext()
+\stoptyping
+
+So yes, you need to know the \CONTEXT\ commands in order to use this mechanism.
+In spite of what you might expect, the codebase involved in this interface is not
+that large. If you know \CONTEXT, and if you know how to call commands, you
+basically can use this \LUA\ method.
+
+The examples that I will give are either (sort of) standalone, i.e.\ they are
+dealt with from \LUA, or they are run within this document. Therefore you will
+see two patterns. If you want to make your own documentation, then you can use
+this variant:
+
+\starttyping
+\startbuffer
+context("See this!")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+\stoptyping
+
+I use anonymous buffers here but you can also use named ones. The other variant
+is:
+
+\starttyping
+\startluacode
+context("See this!")
+\stopluacode
+\stoptyping
+
+This will process the code directly. Of course we could have encoded this
+document completely in \LUA\ but that is not much fun for a manual.
+
+\stopsection
+
+\startsection[title=The main command]
+
+There are a few rules that you need to be aware of. First of all no syntax
+checking is done. Second you need to know what the given commands expects in
+terms of arguments. Third, the type of your arguments matters:
+
+\starttabulate[|||]
+\NC \type{nothing} \EQ just the command, no arguments \NC \NR
+\NC \type{string}  \EQ an argument with curly braces \NC \NR
+\NC \type{array}   \EQ a list between square backets (sometimes optional) \NC \NR
+\NC \type{hash}    \EQ an assignment list between square brackets \NC \NR
+\NC \type{boolean} \EQ when \type {true} a newline is inserted \NC \NR
+\NC                \EQ when \type {false}, omit braces for the next argument \NC \NR
+\stoptabulate
+
+In the code above you have seen examples of this but here are some more:
+
+\starttyping
+context.chapter("Some title")
+context.chapter({ "first" }, "Some title")
+context.startchapter({ title = "Some title", label = "first" })
+\stoptyping
+
+This blob of code is equivalent to:
+
+\starttyping
+\chapter{Some title}
+\chapter[first]{Some title}
+\startchapter[title={Some title},label=first]
+\stoptyping
+
+You can simplify the third line of the \LUA\ code to:
+
+\starttyping
+context.startchapter { title = "Some title", label = "first" }
+\stoptyping
+
+In case you wonder what the distinction is between square brackets and curly
+braces: the first category of arguments concerns settings or lists of options or
+names of instances while the second category normally concerns some text to be
+typeset.
+
+Strings are interpreted as \TEX\ input, so:
+
+\starttyping
+context.mathematics("\\sqrt{2^3}")
+\stoptyping
+
+and if you don't want to escape:
+
+\starttyping
+context.mathematics([[\sqrt{2^3}]])
+\stoptyping
+
+are both correct. As \TEX\ math is a language in its own and a de-facto standard
+way of inputting math this is quite natural, even at the \LUA\ end.
+
+\stopsection
+
+\startsection[title=Spaces and Lines]
+
+\index{spaces}
+\index{lines}
+
+In a regular \TEX\ file, spaces and newline characters are collapsed into one
+space. At the \LUA\ end the same happens. Compare the following examples. First
+we omit spaces:
+
+\startbuffer
+context("left")
+context("middle")
+context("right")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+Next we add spaces:
+
+\startbuffer
+context("left")
+context(" middle ")
+context("right")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+We can also add more spaces:
+
+\startbuffer
+context("left ")
+context(" middle ")
+context(" right")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+In principle all content becomes a stream and after that the \TEX\ parser will do
+its normal work: collapse spaces unless configured to do otherwise. Now take the
+following code:
+
+\startbuffer
+context("before")
+context("word 1")
+context("word 2")
+context("word 3")
+context("after")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+Here we get no spaces between the words at all, which is what we expect. So, how
+do we get lines (or paragraphs)?
+
+\startbuffer
+context("before")
+context.startlines()
+context("line 1")
+context("line 2")
+context("line 3")
+context.stoplines()
+context("after")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+This does not work out well, as again there are no lines seen at the \TEX\ end.
+Newline tokens are injected by passing \type {true} to the \type {context}
+command:
+
+\startbuffer
+context("before")
+context.startlines()
+context("line 1") context(true)
+context("line 2") context(true)
+context("line 3") context(true)
+context.stoplines()
+context("after")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+Don't confuse this with:
+
+\startbuffer
+context("before") context.par()
+context("line 1") context.par()
+context("line 2") context.par()
+context("line 3") context.par()
+context("after")  context.par()
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+There we use the regular \type {\par} command to finish the current paragraph and
+normally you will use that method. In that case, when set, whitespace will be
+added between paragraphs.
+
+This newline issue is a somewhat unfortunate inheritance of traditional \TEX,
+where \type {\n} and \type {\r} mean something different. I'm still not sure if
+the \CLD\ do the right thing as dealing with these tokens also depends on the
+intended effect. Catcodes as well as the \LUATEX\ input parser also play a role.
+Anyway, the following also works:
+
+\startbuffer
+context.startlines()
+context("line 1\n")
+context("line 2\n")
+context("line 3\n")
+context.stoplines()
+\stopbuffer
+
+\typebuffer
+
+\stopsection
+
+\startsection[title=Direct output]
+
+\index{direct output}
+\index{verbose}
+
+The \CONTEXT\ user interface is rather consistent and the use of special input
+syntaxes is discouraged. Therefore, the \LUA\ interface using tables and strings
+works quite well. However, imagine that you need to support some weird macro (or
+a primitive) that does not expect its argument between curly braces or brackets.
+The way out is to precede an argument by another one with the value \type
+{false}. We call this the direct interface. This is demonstrated in the following
+example.
+
+\startbuffer
+\unexpanded\def\bla#1{[#1]}
+
+\startluacode
+context.bla(false,"***")
+context.par()
+context.bla("***")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This results in:
+
+\getbuffer
+
+Here, the first call results in three \type {*} being passed, and \type {#1}
+picks up the first token. The second call to \type {bla} gets \type {{***}}
+passed so here \type {#1} gets the triplet. In practice you will seldom need the
+direct interface.
+
+In \CONTEXT\ for historical reasons, combinations accept the following syntax:
+
+\starttyping
+\startcombination % optional specification, like [2*3]
+  {\framed{content one}} {caption one}
+  {\framed{content two}} {caption two}
+\stopcombination
+\stoptyping
+
+You can also say:
+
+\starttyping
+\startcombination
+  \combination {\framed{content one}} {caption one}
+  \combination {\framed{content two}} {caption two}
+\stopcombination
+\stoptyping
+
+When coded in \LUA, we can feed the first variant as follows:
+
+\startbuffer
+context.startcombination()
+  context.direct("one","two")
+  context.direct("one","two")
+context.stopcombination()
+\stopbuffer
+
+\typebuffer
+
+To give you an idea what this looks like, we render it:
+
+\startlinecorrection[blank]
+\ctxluabuffer
+\stoplinecorrection
+
+So, the \type {direct} function is basically a no|-|op and results in nothing by
+itself. Only arguments are passed. An equivalent but bit more ugly looking is:
+
+\starttyping
+context.startcombination()
+  context(false,"one","two")
+  context(false,"one","two")
+context.stopcombination()
+\stoptyping
+
+\stopsection
+
+\startsection[title=Catcodes]
+
+\index{catcodes}
+
+If you are familiar with the inner working of \TEX, you will know that characters
+can have special meanings. This meaning is determined by their catcodes.
+
+\startbuffer
+context("$x=1$")
+\stopbuffer
+
+\typebuffer
+
+This gives: \ctxluabuffer\ because the dollar tokens trigger inline math mode. If
+you think that this is annoying, you can do the following:
+
+\startbuffer
+context.pushcatcodes("text")
+context("$x=1$")
+context.popcatcodes()
+\stopbuffer
+
+\typebuffer
+
+Now we get: \ctxluabuffer. There are several catcode regimes of
+which only a few make sense in the perspective of the cld
+interface.
+
+\starttabulate[|Tl|l|]
+\NC ctx, ctxcatcodes, context   \NC the normal \CONTEXT\ catcode regime \NC \NR
+\NC prt, prtcatcodes, protect   \NC the \CONTEXT\ protected regime, used for modules \NC \NR
+\NC tex, texcatcodes, plain     \NC the traditional (plain) \TEX\ regime \NC \NR
+\NC txt, txtcatcodes, text      \NC the \CONTEXT\ regime but with less special characters \NC \NR
+\NC vrb, vrbcatcodes, verbatim  \NC a regime specially meant for verbatim \NC \NR
+\NC xml, xmlcatcodes            \NC a regime specially meant for \XML\ processing \NC \NR
+\stoptabulate
+
+In the second case you can still get math:
+
+\starttyping
+context.pushcatcodes("text")
+context.mathematics("x=1")
+context.popcatcodes()
+\stoptyping
+
+When entering a lot of math you can also consider this:
+
+\starttyping
+context.startimath()
+context("x")
+context("=")
+context("1")
+context.stopimath()
+\stoptyping
+
+Module writers of course can use \type {unprotect} and \type {protect} as they do
+at the \TEX\ end.
+
+As we've seen, a function call to \type {context} acts like a print, as in:
+
+\startbuffer
+context("test ")
+context.bold("me")
+context(" first")
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+When more than one argument is given, the first argument is considered a format
+conforming the \type {string.format} function.
+
+\startbuffer
+context.startimath()
+context("%s = %0.5f",utf.char(0x03C0),math.pi)
+context.stopimath()
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+This means that when you say:
+
+\starttyping
+context(a,b,c,d,e,f)
+\stoptyping
+
+the variables \type {b} till \type {f} are passed to the format and when the
+format does not use them, they will not end up in your output.
+
+\starttyping
+context("%s %s %s",1,2,3)
+context(1,2,3)
+\stoptyping
+
+The first line results in the three numbers being typeset, but in the second case
+only the number~1 is typeset.

+
+\startsection[title=Introduction]
+
+One of the interesting aspects of \TEX\ is that it provides control over fonts
+and \LUATEX\ provides quite some. In \CONTEXT\ we support basic functionality,
+like \OPENTYPE\ features, as well as some extra functionality. We also have a
+mechanism for making virtual fonts which is mostly used for the transition from
+\TYPEONE\ math fonts to \OPENTYPE\ math fonts. Instead of hard coding specific
+details in the core \LUA\ code, we use so called \LUA\ Font Goodies to control
+them. These goodies are collected in tables and live in files. When a font is
+loaded, one or more such goodie files can be loaded alongside.
+
+In the following typescript we load a goodies file that defines a virtual Lucida
+math font. The goodie file is loaded immediately and some information in the
+table is turned into a form that permits access later on: the virtual font id
+\type {lucida-math} that is used as part of the font specification.
+
+\starttyping
+\starttypescript [math] [lucida]
+    \loadfontgoodies[lucida-math]
+    \definefontsynonym[MathRoman][lucidamath@lucida-math]
+\stoptypescript
+\stoptyping
+
+Not all information is to be used directly. Some can be accessed when needed. In
+the following case the file \type {dingbats.lfg} gets loaded (only once) when the
+font is actually used. In that file, there is information that is used by the
+\type {unicoding} feature.
+
+\starttyping
+\definefontfeature
+  [dingbats]
+  [mode=base,
+   goodies=dingbats,
+   unicoding=yes]
+
+\definefont[dingbats][file:dingbats][features=dingbats]
+\stoptyping
+
+In the following sections some aspects of goodies are discussed. We don't go into
+details of what these goodies are, but just stick to the \LUA\ side of the
+specification.
+
+\stopsection
+
+\startsection[title=Virtual math fonts]
+
+A virtual font is defined using the \type {virtuals} entry in the \type
+{mathematics} subtable. As \TYPEONE\ fonts are used, an additional table \type
+{mapfiles} is needed to specify the files that map filenames onto real files.
+
+\startsmalltyping

+        { name = "rpxmi.tfm", vector = "tex-mi", skewchar=0x7F },
+        { name = "rpxpplri.tfm", vector = "tex-it", skewchar=0x7F },

+      },
+    }
+  }
+}
+\stopsmalltyping
+
+Here the \type {px-math} virtual font is defined. A series of fonts is loaded and
+combined into one. The \type {vector} entry is used to tell the builder how to
+map the glyphs onto \UNICODE. Additional vectors can be defined, for instance:
+
+\starttyping
+fonts.encodings.math["mine"] = {
+    [0x1234] = 0x56,
+}
+\stoptyping
+
+Eventually these specifications wil be replaced by real \OPENTYPE\ fonts, but
+even then we will keep the virtual definitions around.
+
+\startsection[title=Math alternates]
+
+In addition to the official \type {ssty} feature for enforcing usage of script
+and scriptscript glyphs, some stylistic alternates can be present.

+
+In this example you see several virtuals defined which is due to the fact that
+Latin Modern has design sizes. The values (like \type {twelve} are tables defined
+before the return happens and are not shown here. The variables are rather
+\CONTEXT\ specific, and the parameters are those that come with regular
+\OPENTYPE\ math fonts (so the example names are invalid).
+
+In the following example we show two wasy to change parameters. In this case we
+have a regular \OPENTYPE\ math font. First we install a patch to the font itself.
+That change will be cached. We could also have changed that parameter using the
+goodies table. The first method is the oldest.

+\startsection[title=The regular interface]
+
+If you are familiar with \CONTEXT, which by now probably is the case, you will
+have noticed that it integrates the \METAPOST\ graphic subsystem. Drawing a
+graphic is not that complex:
+
+\startbuffer
+context.startMPcode()
+context [[
+  draw
+    fullcircle scaled 1cm
+    withpen pencircle scaled 1mm
+    withcolor .5white
+    dashed dashpattern (on 2mm off 2mm) ;
+ ]]
+context.stopMPcode()
+\stopbuffer
+
+\typebuffer
+
+We get a gray dashed circle rendered with an one millimeter thick line:
+
+\startlinecorrection
+\ctxluabuffer
+\stoplinecorrection
+
+So, we just use the regular commands and pass the drawing code as strings.
+Although \METAPOST\ is a rather normal language and therefore offers loops and
+conditions and the lot, you might want to use \LUA\ for anything else than the
+drawing commands. Of course this is much less efficient, but it could be that you
+don't care about speed. The next example demonstrates the interface for building
+graphics piecewise.
+
+\startbuffer
+context.resetMPdrawing()
+
+context.startMPdrawing()
+context([[fill fullcircle scaled 5cm withcolor (0,0,.5) ;]])
+context.stopMPdrawing()
+
+context.MPdrawing("pickup pencircle scaled .5mm ;")
+context.MPdrawing("drawoptions(withcolor white) ;")
+
+for i=0,50,5 do
+  context.startMPdrawing()
+  context("draw fullcircle scaled %smm ;",i)
+  context.stopMPdrawing()
+end
+
+for i=0,50,5 do
+  context.MPdrawing("draw fullsquare scaled " .. i .. "mm ;")
+end
+
+context.MPdrawingdonetrue()
+
+context.getMPdrawing()
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\startlinecorrection
+\ctxluabuffer
+\stoplinecorrection
+
+I the first loop we can use the format options associated with the simple \type
+{context} call. This will not work in the second case. Even worse, passing more
+than one argument will definitely give a faulty graphic definition. This is why
+we have a special interface for \METAFUN. The code above can also be written as:
+
+\startbuffer
+local metafun = context.metafun
+
+metafun.start()
+
+metafun("fill fullcircle scaled 5cm withcolor %s ;",
+    metafun.color("darkblue"))
+
+metafun("pickup pencircle scaled .5mm ;")
+metafun("drawoptions(withcolor white) ;")
+
+for i=0,50,5 do
+  metafun("draw fullcircle scaled %smm ;",i)
+end
+
+for i=0,50,5 do
+  metafun("draw fullsquare scaled %smm ;",i)
+end
+
+metafun.stop()
+\stopbuffer
+
+\typebuffer
+
+Watch the call to \type {color}, this will pass definitions at the \TEX\ end to
+\METAPOST. Of course you really need to ask yourself \quotation {Do I want to use
+\METAPOST\ this way?}. Using \LUA\ loops instead of \METAPOST\ ones makes much
+more sense in the following case:
+
+\startbuffer
+local metafun = context.metafun
+
+function metafun.barchart(t)
+  metafun.start()
+  local t = t.data
+  for i=1,#t do
+    metafun("draw unitsquare xyscaled(%s,%s) shifted (%s,0);",
+      10, t[i]*10, i*10)
+  end
+  metafun.stop()
+end
+
+local one = { 1, 4, 6, 2, 3, }
+local two = { 8, 1, 3, 5, 9, }
+
+context.startcombination()
+  context.combination(metafun.delayed.barchart { data = one }, "one")
+  context.combination(metafun.delayed.barchart { data = two }, "two")
+context.stopcombination()
+\stopbuffer
+
+\typebuffer
+
+We get two barcharts alongside:
+
+\startlinecorrection
+\ctxluabuffer
+\stoplinecorrection
+
+\startbuffer
+local template = [[
+  path p, q ; color c[] ;
+  c1 := \MPcolor{darkblue} ;
+  c2 := \MPcolor{darkred} ;
+  p := fullcircle scaled 50 ;
+  l := length p ;
+  n := %s ;
+  q := subpath (0,%s/n*l) of p ;
+  draw q withcolor c2 withpen pencircle scaled 1 ;
+  fill fullcircle scaled 5 shifted point length q of q withcolor c1 ;
+  setbounds currentpicture to unitsquare shifted (-0.5,-0.5) scaled 60 ;
+  draw boundingbox currentpicture withcolor c1 ;
+  currentpicture := currentpicture xsized(1cm) ;
+]]
+
+local function steps(n)
+  for i=0,n do
+    context.metafun.start()
+      context.metafun(template,n,i)
+    context.metafun.stop()
+    if i < n then
+        context.quad()

+
+Using a template is quite convenient but at some point you can loose track of the
+replacement values. Also, adding an extra value can force you to adapt the
+following ones which enlarges the change for making an error. An alternative is
+to use the template mechanism. Although this mechanism was originally made for
+other purposes, you can use it for whatever you like.
+
+\startbuffer
+local template = [[
+    path p ; p := fullcircle scaled 4cm ;
+    draw p withpen pencircle scaled .5mm withcolor red ;
+    freedotlabel ("%lefttop%",    point 1 of p,origin) ;
+    freedotlabel ("%righttop%",   point 3 of p,origin) ;
+    freedotlabel ("%leftbottom%", point 5 of p,origin) ;
+    freedotlabel ("%rightbottom%",point 7 of p,origin) ;
+]]
+
+local variables = {
+  lefttop     = "one",
+  righttop    = "two",
+  leftbottom  = "three",
+  rightbottom = "four" ,
+}
+
+context.metafun.start()
+  context.metafun(utilities.templates.replace(template,variables))
+context.metafun.stop()
+\stopbuffer
+
+\typebuffer
+
+Here we use named placeholders and pass a table with associated values to the
+replacement function. Apart from convenience it's also more readable. And the
+overhead is rather minimal.
+
+\startlinecorrection
+\ctxluabuffer
+\stoplinecorrection
+
+To some extent we fool ourselves with this kind of \LUA fication of \METAPOST\
+code. Of course we can make a nice \METAPOST\ library and put the code in a macro
+instead. In that sense, doing this in \CONTEXT\ directly often gives better and
+more efficient code.
+
+Of course you can use all relevant commands in the \LUA\ interface, like:
+
+\starttyping
+context.startMPpage()
+  context("draw origin")
+  for i=0,100,10 do
+    context("..{down}(%d,0)",i)
+  end
+  context(" withcolor \\MPcolor{darkred} ;")
+context.stopMPpage()
+\stoptyping
+
+to get a graphic that has its own page. Don't use the \type {metafun} namespace
+here, as it will not work here. This drawing looks like:
+
+\startlinecorrection
+\startluacode
+context.startMPcode()
+  context("draw origin")
+  for i=0,100,10 do
+    context("..{down}(%d,0)",i)
+  end
+  context(" withcolor red ;")
+context.stopMPcode()
+\stopluacode
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title=The \LUA\ interface]
+
+Messing around with graphics is normally not needed and if you do it, you'd
+better know what you're doing. For \TEX\ a graphic is just a black box: a
+rectangle with dimensions. You specify a graphic, in a format that the backend
+can deal with, either or not apply some scaling and from then on a reference to
+that graphic, normally wrapped in a normal \TEX\ box, enters the typesetting
+machinery. Because the backend, the part that is responsible for translating
+typeset content onto a viewable or printable format like \PDF, is built into
+\LUATEX, at some point the real image has to be injected and the backend can only
+handle a few image formats: \PNG, \JPG, \JBIG\ and \PDF.
+
+In \CONTEXT\ some more image formats are supported but in practice this boils
+down to converting the image to a format that the backend can handle. Such a
+conversion depends on an external programs and in order not to redo the
+conversion each run \CONTEXT\ keeps track of the need to redo it.
+
+Some converters are built in, for example one that deals with \GIF\ images. This
+is normally not a preferred format, but it happens that we have to deal with it
+in cases where organizations use that format (if only because they use the web).
+Here is how this works at the \LUA\ end:
+
+\starttyping
+figures.converters.gif = {
+  pdf = function(oldname,newname)
+    os.execute(string.format("gm convert %s %s",oldname,newname))
+  end
+}
+\stoptyping
+
+We use \type {gm} (Graphic Magic) for the conversion and pass the old and new
+names. Given this definition at the \TEX\ end we can say:
+
+\starttyping
+\externalfigure[whatever.gif][width=4cm]
+\stoptyping
+
+Here is a another one:
+
+\starttyping
+figures.converters.bmp = {
+  pdf = function(oldname,newname)
+      os.execute(string.format("gm convert %s %s",oldname,newname))
+  end
+}
+\stoptyping
+
+In both examples we convert to \PDF\ because including this filetype is quite
+fast. But you can also go to other formats:
+
+\starttyping
+figures.converters.png = {
+  png = function(oldname,newname,resolution)
+    local command = string.format('gm convert -depth 1 "%s" "%s"',oldname,newname)
+    logs.report(string.format("running command %s",command))
+    os.execute(command)
+  end
+}
+\stoptyping
+
+Instead of directly defining such a table, you can better do this:
+
+\starttyping
+figures.converters.png = figures.converters.png or { }
+
+figures.converters.png.png = function(oldname,newname,resolution)
+  local command = string.format('gm convert -depth 1 "%s" "%s"',oldname,newname)
+  logs.report(string.format("running command %s",command))
+  os.execute(command)
+end
+\stoptyping
+
+Here we check if a table exists and if not we extend the table. Such converters
+work out of the box if you specify the suffix, but you can also opt for a simple:
+
+\starttyping
+\externalfigure[whatever][width=4cm]
+\stoptyping
+
+In this case \CONTEXT\ will check for all known supported formats, which is not
+that efficient when no graphic can be found. In order to let for instance files
+with suffix \type {bmp} can be included you have to register it as follows. The
+second argument is the target.
+
+\starttyping
+figures.registersuffix("bmp","bmp")

+\startchapter[title=Introduction]
+
+Sometimes you hear folks complain about the \TEX\ input language, i.e.\ the
+backslashed commands that determine your output. Of course, when alternatives are
+being discussed every one has a favourite programming language. In practice
+coding a document in each of them triggers similar sentiments with regards to
+coding as \TEX\ itself does.
+
+So, just for fun, I added a couple of commands to \CONTEXT\ \MKIV\ that permit
+coding a document in \LUA. In retrospect it has been surprisingly easy to
+implement a feature like this using metatables. Of course it's a bit slower than
+using \TEX\ as input language but sometimes the \LUA\ interface is more readable
+given the problem at hand.
+
+After a while I decided to use that interface in non|-|critical core \CONTEXT\
+code and in styles (modules) and solutions for projects. Using the \LUA\ approach
+is sometimes more convenient, especially if the code mostly manipulates data. For
+instance, if you process \XML\ files of database output you can use the interface
+that is available at the \TEX\ end, or you can use \LUA\ code to do the work, or
+you can use a combination. So, from now on, in \CONTEXT\ you can code your style
+and document source in (a mixture of) \TEX, \XML, \METAPOST\ and in \LUA.
+
+In the following chapters I will introduce typesetting in \LUA, but as we rely on
+\CONTEXT\ it is unavoidable that some regular \CONTEXT\ code shows up. The fact
+that you can ignore backslashes does not mean that you can do without knowledge
+of the underlying system. I expect that the user is somewhat familiar with this
+macro package. Some chapters are follow ups on articles or earlier publications.
+
+Some information (and mechanism) show up in more than one chapter. This is a side
+effect of \LUA\ being integrated in many places, so an isolated discussion is a
+bit hard.
+
+In the meantime most of the code is rather stable and proven. However, this
+manual will never be complete. You can find examples all over the code base, and
+duplicating everything here makes no sense. If you find errors, please let me
+know. If you think that something is missing, you can try to convince me to add
+it. It's hard to keep up with what gets added so input is welcome.

+\startchapter[title={Logging}]
+
+Logging and localized messages have always been rather standardized in \CONTEXT,
+so upgrading the related mechanism had been quite doable. In \MKIV\ for a while
+we had two systems in parallel: the old one, mostly targeted at messages at the
+\TEX\ end, and a new one used at the \LUA\ end. But when more and more hybrid
+code showed up, integrating both systems made sense.
+
+Most logging concerns tracing and can be turned on and off on demand. This kind
+of control is now possible for all messages. Given that the right interfaces are
+used, you can turn off all messages:
+
+\starttyping
+context --silent
+\stoptyping
+
+This was already possible in \MKII, but there \TEX's own messages still were
+visible. More important is that we have control:
+
+\starttyping
+context --silent=structure*,resolve*,font*
+\stoptyping
+
+This will disable all reporting for these three categories. It is also possible
+to only disable messages to the console:
+
+\starttyping
+context --noconsole
+\stoptyping
+
+In \CONTEXT\ you can use directives:
+
+\starttyping
+\enabledirectives[logs.blocked=structure*,resolve*,font*]
+\enabledirectives[logs.target=file]
+\stoptyping
+
+As all logging is under \LUA\ control and because this (and other) kind of
+control has to kick in early in the initialization the code might look somewhat
+tricky. Users won't notice this because they only deal with the formal interface.
+Here we will only discuss the \LUA\ interfaces.
+
+Messages related to tracing are done as follows:
+
+\starttyping
+local report_whatever = logs.reporter("modules","whatever")
+
+report_whatever("not found: %s","this or that")
+\stoptyping
+
+The first line defined a logger in the category \type {modules}. You can give a
+second argument as well, the subcategory. Both will be shown as part of the
+message, of which an example is given in the second line.
+
+These messages are shown directly, that is, when the function is called. However,
+when you generate \TEX\ code, as we discuss in this document, you need to make
+sure that the message is synchronized with that code. This can be done with a
+messenger instead of a reporter.
+
+\starttyping
+local report_numbers = logs.reporter("numbers","check")
+local status_numbers = logs.messenger("numbers","check")
+
+status_numbers("number 1: %s, number 2: %s",123,456)
+report_numbers("number 1: %s, number 2: %s",456,123)
+\stoptyping
+
+Both reporters and messages are localized when the pattern given as first
+argument can be found in the \type {patterns} subtable of the interface messages.
+Categories and subcategories are also translated, but these are looked up in the
+\type {translations} subtable. So in the case of
+
+\starttyping
+report_whatever("found: %s",filename)
+report_whatever("not found: %s",filename)
+\stoptyping
+
+you should not be surprised if it gets translated. Of course the category and
+subcategory provide some contextual information.

+\startchapter[title=Lua Functions]
+
+\startsection[title={Introduction}]
+
+When you run \CONTEXT\ you have some libraries preloaded. If you look into the
+\LUA\ files you will find more than is discussed here, but keep in mind that what
+is not documented, might be gone or done different one day. Some extensions live
+in the same namespace as those provided by stock \LUA\ and \LUATEX, others have
+their own. There are many more functions and the more obscure (or never being
+used) ones will go away.
+
+The \LUA\ code in \CONTEXT\ is organized in quite some modules. Those with names
+like \type {l-*.lua} are rather generic and are automatically available when you
+use \type {mtxrun} to run a \LUA\ file. These are discusses in this chapter. A
+few more modules have generic properties, like some in the categories \type
+{util-*.lua}, \type {trac-*.lua}, \type {luat-*.lua}, \type {data-*.lua} and
+\type {lxml-*.lua}. They contain more specialized functions and are discussed
+elsewhere.
+
+Before we move on the the real code, let's introduce a handy helper:
+
+\starttyping
+inspect(somevar)
+\stoptyping
+
+Whenever you feel the need to see what value a variable has you can insert this
+function to get some insight. It knows how to deal with several data types.
+
+\stopsection
+
+\startsection[title={Tables}]
+
+\startsummary[title={[lua] concat}]
+
+These functions come with \LUA\ itself and are discussed in detail in the \LUA\
+reference manual so we stick to some examples. The \type {concat} function
+stitches table entries in an indexed table into one string, with an optional
+separator in between. If can also handle a slice of the table
+
+\starttyping
+local str = table.concat(t)
+local str = table.concat(t,separator)
+local str = table.concat(t,separator,first)
+local str = table.concat(t,separator,first,last)
+\stoptyping
+
+Only strings and numbers can be concatenated.
+
+\ShowLuaExampleThree {table} {concat} {{"a","b","c","d","e"}}
+\ShowLuaExampleThree {table} {concat} {{"a","b","c","d","e"},"+"}
+\ShowLuaExampleThree {table} {concat} {{"a","b","c","d","e"},"+",2,3}
+
+\stopsummary
+
+\startsummary[title={[lua] insert remove}]
+
+You can use \type {insert} and \type {remove} for adding or replacing entries in
+an indexed table.
+
+\starttyping
+table.insert(t,value,position)
+value = table.remove(t,position)
+\stoptyping
+
+The position is optional and defaults to the last entry in the table. For
+instance a stack is built this way:
+
+\starttyping
+table.insert(stack,"top")
+local top = table.remove(stack)
+\stoptyping
+
+Beware, the \type {insert} function returns nothing. You can provide an
+additional position:
+
+\starttyping
+table.insert(list,"injected in slot 2",2)
+local thiswastwo = table.remove(list,2)
+\stoptyping
+
+\stopsummary
+
+\startsummary[title={[lua] unpack}]
+
+You can access entries in an indexed table as follows:
+
+\starttyping
+local a, b, c = t[1], t[2], t[3]
+\stoptyping
+
+but this does the same:
+
+\starttyping
+local a, b, c = table.unpack(t)
+\stoptyping
+
+This is less efficient but there are situations where \type {unpack}
+comes in handy.
+
+\stopsummary
+
+\startsummary[title={[lua] sort}]
+
+Sorting is done with \type {sort}, a function that does not return a value but
+operates on the given table.
+
+\starttyping
+table.sort(t)
+table.sort(t,comparefunction)
+\stoptyping
+
+The compare function has to return a consistent equivalent of \type {true} or
+\type {false}. For sorting more complex data structures there is a specialized
+sort module available.
+
+\ShowLuaExampleFour {table} {sort} {{"a","b","c"}} {}
+\ShowLuaExampleFour {table} {sort} {{"a","b","c"}} {,function(x,y) return x > y end}
+\ShowLuaExampleFour {table} {sort} {{"a","b","c"}} {,function(x,y) return x < y end}
+
+\stopsummary
+
+\startsummary[title={sorted}]
+
+The built|-|in \type {sort} function does not return a value but sometimes it can be
+if the (sorted) table is returned. This is why we have:
+
+\starttyping
+local a = table.sorted(b)
+\stoptyping
+
+\stopsummary
+
+% table.strip
+
+\startsummary[title={keys sortedkeys sortedhashkeys sortedhash}]
+
+The \type {keys} function returns an indexed list of keys. The order is undefined
+as it depends on how the table was constructed. A sorted list is provided by
+\type {sortedkeys}. This function is rather liberal with respect to the keys. If
+the keys are strings you can use the faster alternative \type {sortedhashkeys}.
+
+\starttyping
+local s = table.keys (t)
+local s = table.sortedkeys (t)
+local s = table.sortedhashkeys (t)
+\stoptyping
+
+Because a sorted list is often processed there is also an iterator:
+
+\starttyping
+for key, value in table.sortedhash(t) do
+    print(key,value)
+end
+\stoptyping
+
+There is also a synonym \type {sortedpairs} which sometimes looks more natural
+when used alongside the \type {pairs} and \type {ipairs} iterators.
+
+\ShowLuaExampleTwo {table} {keys}           {{ [1] = 2, c = 3, [true] = 1 }}
+\ShowLuaExampleTwo {table} {sortedkeys}     {{ [1] = 2, c = 3, [true] = 1 }}
+\ShowLuaExampleTwo {table} {sortedhashkeys} {{ a = 2, c = 3, b = 1 }}
+
+\stopsummary
+
+\startsummary[title={serialize print tohandle tofile}]
+
+The \type {serialize} function converts a table into a verbose representation.
+The \type {print} function does the same but prints the result to the console
+which is handy for tracing. The \type {tofile} function writes the table to a
+file, using reasonable chunks so that less memory is used. The fourth variant
+\type {tohandle} takes a handle so that you can do whatever you like with the
+result.
+
+\starttyping
+table.serialize (root, name, reduce, noquotes, hexify)
+table.print (root, name, reduce, noquotes, hexify)
+table.tofile (filename, root, name, reduce, noquotes, hexify)
+table.tohandle (handle, root, name, reduce, noquotes, hexify)
+\stoptyping
+
+The serialization can be controlled in several ways. Often only the first two
+options makes sense:
+
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }, "name"}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }, true}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }, false}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }, "return"}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2 }, 12}
+
+\ShowLuaExampleOne {table} {serialize} {{ a = 2, [3] = "b", [true] = "6" }, nil, true}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2, [3] = "b", [true] = "6" }, nil, true, true}
+\ShowLuaExampleOne {table} {serialize} {{ a = 2, [3] = "b", [true] = "6" }, nil, true, true, true}
+
+In \CONTEXT\ there is also a \type {tocontext} function that typesets the table
+verbose. This is handy for manuals and tracing.
+
+\stopsummary
+
+\startsummary[title={identical are_equal}]
+
+These two function compare two tables that have a similar structure. The \type
+{identical} variant operates on a hash while \type {are_equal} assumes an indexed
+table.
+
+\starttyping
+local b = table.identical (one, two)
+local b = table.are_equal (one, two)
+\stoptyping
+
+\ShowLuaExampleThree {table} {identical} {{ a = { x = 2 } }, { a = { x = 3 } }}
+\ShowLuaExampleThree {table} {identical} {{ a = { x = 2 } }, { a = { x = 2 } }}
+
+\ShowLuaExampleThree {table} {are_equal} {{ a = { x = 2 } }, { a = { x = 3 } }}
+\ShowLuaExampleThree {table} {are_equal} {{ a = { x = 2 } }, { a = { x = 2 } }}
+
+\ShowLuaExampleThree {table} {identical} {{ "one", "two" }, { "one", "two" }}
+\ShowLuaExampleThree {table} {identical} {{ "one", "two" }, { "two", "one" }}
+
+\ShowLuaExampleThree {table} {are_equal} {{ "one", "two" }, { "one", "two" }}
+\ShowLuaExampleThree {table} {are_equal} {{ "one", "two" }, { "two", "one" }}
+
+\stopsummary
+
+\startsummary[title={tohash fromhash swapped swaphash reversed reverse mirrored}]
+
+We use \type {tohash} quite a lot in \CONTEXT. It converts a list into a hash so
+that we can easily check if (a string) is in a given set. The \type {fromhash}
+function does the opposite: it creates a list of keys from a hashed table where
+each value that is not \type {false} or \type {nil} is present.
+
+\starttyping
+local hashed  = table.tohash  (indexed)
+local indexed = table.fromhash(hashed)
+\stoptyping
+
+The function \type {swapped} turns keys into values vise versa while the \type
+{reversed} and \type {reverse} reverses the values in an indexed table. The last
+one reverses the table itself (in|-|place).
+
+\starttyping
+local swapped  = table.swapped  (indexedtable)
+local reversed = table.reversed (indexedtable)
+local reverse  = table.reverse  (indexedtable)
+local mirrored = table.mirrored (hashedtable)
+\stoptyping
+
+\ShowLuaExampleTwo {table} {tohash}   {{ "a", "b", "c" }}
+\ShowLuaExampleTwo {table} {fromhash} {{ a = true, b = false, c = true }}
+\ShowLuaExampleTwo {table} {swapped}  {{ "a", "b", "c" }}
+\ShowLuaExampleTwo {table} {reversed} {{ "a", "b", "c" }}
+\ShowLuaExampleTwo {table} {reverse}  {{ 1, 2, 3, 4 }}
+\ShowLuaExampleTwo {table} {mirrored} {{ a = "x", b = "y", c = "z" }}
+
+\stopsummary
+
+\startsummary[title={append prepend}]
+
+These two functions operate on a pair of indexed tables. The first table gets
+appended or prepended by the second. The first table is returned as well.
+
+\starttyping
+table.append (one, two)
+table.prepend(one, two)
+\stoptyping
+
+The functions are similar to loops using \type {insert}.
+
+\ShowLuaExampleTwo {table} {append}  {{ "a", "b", "c" }, { "d", "e" }}
+\ShowLuaExampleTwo {table} {prepend} {{ "a", "b", "c" }, { "d", "e" }}
+
+\stopsummary
+
+\startsummary[title={merge merged imerge imerged}]
+
+You can merge multiple hashes with \type {merge} and indexed tables with \type
+{imerge}. The first table is the target and is returned.
+
+\starttyping
+table.merge   (one, two, ...)
+table.imerge  (one, two, ...)
+\stoptyping
+
+The variants ending with a \type {d} merge the given list of tables and return
+the result leaving the first argument untouched.
+
+\starttyping
+local merged = table.merged  (one, two, ...)
+local merged = table.imerged (one, two, ...)
+\stoptyping
+
+\ShowLuaExampleTwo {table} {merge}  {{ a = 1, b = 2, c = 3 }, { d = 1 }, { a = 0 }}
+\ShowLuaExampleTwo {table} {imerge} {{ "a", "b", "c" }, { "d", "e" }, { "f", "g" }}
+
+% \ShowLuaExampleTwo {table} {merged}   {{ a = 1, b = 2, c = 3 }, { d = 1 }, { a = 0 }}
+% \ShowLuaExampleTwo {table} {imerged}  {{ "a", "b", "c" }, { "d", "e" }, { "f", "g" }}
+
+\stopsummary
+
+\startsummary[title={copy fastcopy}]
+
+When copying a table we need to make a real and deep copy. The \type {copy}
+function is an adapted version from the \LUA\ wiki. The \type {fastopy} is faster
+because it does not check for circular references and does not share tables when
+possible. In practice using the fast variant is okay.
+
+\starttyping
+local copy = table.copy    (t)
+local copy = table.fastcopy(t)
+\stoptyping
+
+\stopsummary
+
+\startsummary[title={flattened}]
+
+A nested table can be unnested using \type {flattened}. Normally you will only
+use this function if the content is somewhat predictable. Often using one of the
+merge functions does a similar job.
+
+\starttyping
+local flattened = table.flatten(t)
+\stoptyping
+
+\ShowLuaExampleTwo {table} {flattened} {{ a = 1, b = 2, { c = 3 }, d = 4}}
+\ShowLuaExampleTwo {table} {flattened} {{ 1, 2, { 3, { 4 } }, 5}}
+\ShowLuaExampleTwo {table} {flattened} {{ 1, 2, { 3, { 4 } }, 5}, 1}
+\ShowLuaExampleTwo {table} {flattened} {{ a = 1, b = 2, { c = 3 }, d = 4}}
+\ShowLuaExampleTwo {table} {flattened} {{ 1, 2, { 3, { c = 4 } }, 5}}
+\ShowLuaExampleTwo {table} {flattened} {{ 1, 2, { 3, { c = 4 } }, 5}, 1}
+
+\stopsummary
+
+\startsummary[title={loweredkeys}]
+
+The name says it all: this function returns a new table with the keys being lower
+case. This is handy in cases where the keys have a change to be inconsistent, as
+can be the case when users input keys and values in less controlled ways.
+
+\starttyping
+local normalized = table.loweredkeys { a = "a", A = "b", b = "c" }
+\stoptyping
+
+\ShowLuaExampleTwo {table} {loweredkeys} {{ a = 1, b = 2, C = 3}}
+
+\stopsummary
+
+\startsummary[title={contains}]
+
+This function works with indexed tables. Watch out, when you look for a match,
+the number \type {1} is not the same as string \type {"1"}. The function returns
+the index or \type {false}.
+
+\starttyping
+if table.contains(t, 5 ) then ... else ... end
+if table.contains(t,"5") then ... else ... end
+\stoptyping
+
+\ShowLuaExampleThree {table} {contains} {{ "a", 2, true, "1"}, 1}
+\ShowLuaExampleThree {table} {contains} {{ "a", 2, true, "1"}, "1"}
+
+\stopsummary
+
+\startsummary[title={unique}]
+
+When a table (can) contain duplicate entries you can get rid of them by using the
+\type {unique} helper:
+
+\starttyping
+local t = table.unique { 1, 2, 3, 4, 3, 2, 5, 6 }
+\stoptyping
+
+\ShowLuaExampleTwo {table} {unique} { { "a", "b", "c", "a", "d" } }
+
+\stopsummary
+
+\startsummary[title={count}]
+
+The name speaks for itself: this function counts the number of entries in the
+given table. For an indexed table \type {#t} is faster.
+
+\starttyping
+local n = table.count(t)
+\stoptyping
+
+\ShowLuaExampleThree {table} {count} {{ 1, 2, [4] = 4, a = "a" }}
+
+\stopsummary
+
+\startsummary[title={sequenced}]
+
+Normally, when you trace a table, printing the serialized version is quite
+convenient. However, when it concerns a simple table, a more compact variant is:
+
+\starttyping
+print(table.sequenced(t, separator))
+\stoptyping
+
+% beware: by default sequences has | as separator
+
+\ShowLuaExampleThree {table} {sequenced} {{ 1, 2, 3, 4}}
+\ShowLuaExampleThree {table} {sequenced} {{ 1, 2, [4] = 4, a = "a" }, ", "}
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=Math]
+
+In addition to the built-in math function we provide: \type {round}, \type {odd},
+\type {even}, \type {div}, \type {mod}, \type {sind}, \type {cosd} and
+\type {tand}.
+
+At the \TEX\ end we have a helper \type {luaexpr} that you can use to do
+calculations:
+
+\startbuffer
+  \luaexpr{1 + 2.3 * 4.5 + math.pi} = \cldcontext{1 + 2.3 * 4.5 + math.pi}
+\stopbuffer
+
+\typebuffer
+
+Both calls return the same result, but the first one is normally faster than the
+\type {context} command which has quite some overhead.
+
+\blank \getbuffer \blank
+
+The \type {\luaexpr} command can also better deal with for instance conditions,
+where it returns \type {true} or \type {false}, while \type {\cldcontext} would
+interpret the boolean value as a special signal.
+
+\stopsection
+
+\startsection[title=Booleans]
+
+\startsummary[title={tonumber}]
+
+This function returns the number one or zero. You will seldom need this function.
+
+\starttyping
+local state = boolean.tonumber(str)
+\stoptyping
+
+\ShowLuaExampleThree {boolean} {tonumber} {true}
+
+\stopsummary
+
+\startsummary[title={toboolean}]
+
+When dealing with configuration files or tables a bit flexibility in setting a
+state makes sense, if only because in some cases it's better to say \type {yes}
+than \type {true}.
+
+\starttyping
+local b = toboolean(str)
+local b = toboolean(str,tolerant)
+\stoptyping
+
+When the second argument is true, the strings \type {true}, \type {yes}, \type
+{on}, \type {1}, \type {t} and the number \type {1} all turn into \type {true}.
+Otherwise only \type {true} is honoured. This function is also defined in the
+global namespace.
+
+\ShowLuaExampleThree {string} {toboolean} {"true"}
+\ShowLuaExampleThree {string} {toboolean} {"yes"}
+\ShowLuaExampleThree {string} {toboolean} {"yes",true}
+
+\stopsummary
+
+\startsummary[title={is_boolean}]
+
+This function is somewhat similar to the previous one. It interprets the strings
+\type {true}, \type {yes}, \type {on} and \type {t} as \type {true} and
+\type{false}, \type {no}, \type {off} and \type {f} as \type {false}. Otherwise
+\type {nil} is returned, unless a default value is given, in which case that is
+returned.
+
+\starttyping
+if is_boolean(str)         then ... end
+if is_boolean(str,default) then ... end
+\stoptyping
+
+\ShowLuaExampleThree {string} {is_boolean} {"true"}
+\ShowLuaExampleThree {string} {is_boolean} {"off"}
+\ShowLuaExampleThree {string} {is_boolean} {"crap",true}
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=Strings]
+
+\LUA\ strings are simply sequences of bytes. Of course in some places special
+treatment takes place. For instance \type {\n} expands to one or more characters
+representing a newline, depending on the operating system, but normally, as long
+as you manipulate strings in the perspective of \LUATEX, you don't need to worry
+about such issues too much. As \LUATEX\ is a \UTF-8 engine, strings normally are
+in that encoding but again, it does not matter much as \LUA\ is quite agnostic
+about the content of strings: it does not care about three characters reflecting
+one \UNICODE\ character or not. This means that when you use for instance the
+functions discussed here, or use libraries like \type {lpeg} behave as you
+expect.
+
+Versions later than 0.75 are likely to have some basic \UNICODE\ support on board
+but we can easily adapt to that. At least till \LUATEX\ version 0.75 we provided
+the \type {slunicode} library but users cannot assume that that will be present for
+ever. If you want to mess around with \UTF\ string, use the \type {utf} library
+instead as that is the one we provide in \MKIV. It presents the stable interface to
+whatever \LUA\ itself provides and|/|or what \LUATEX\ offers and|/|or what
+is there because \MKIV\ implements it.

+\startsummary[title={[lua] gsub}]
+
+There are two ways of analyzing the content of a string. The more modern and
+flexible approach is to use \type {lpeg}. The other one uses some functions in
+the \type {string} namespace that accept so called patterns for matching. While
+\type {lpeg} is more powerfull than regular expressions, the pattern matching is
+less powerfull but sometimes faster and also easier to specify. In many cases it
+can do the job quite well.
+
+\starttyping
+local new, count = string.gsub(old,pattern,replacement)
+\stoptyping
+
+The replacement can be a function. Often you don't want the number
+of matches, and the way to avoid this is either to store the result
+in a variable:
+
+\starttyping
+local new = string.gsub(old,"lua","LUA")
+print(new)
+\stoptyping
+
+or to use parentheses to signal the interpreter that only one value
+is return.
+
+\starttyping
+print((string.gsub(old,"lua","LUA"))
+\stoptyping
+
+Patterns can be more complex so you'd better read the \LUA\ manual if you want to
+know more about them.

+\ShowLuaExampleThree {string} {gsub} {"abcdef","b","B"}

+\stoptyping
+
+If you're only interested if there is a match at all, it's enough to know that
+there is a first position. No match returns \type {nil}. So,
+
+\starttyping
+if find("luatex","tex") then ... end
+\stoptyping
+
+works out okay. You can pass an extra argument to \type {find} that indicates the
+start position. So you can use this function to loop over all matches: just start
+again at the end of the last match.
+
+A fourth optional argument is a boolean that signals not to interpret the pattern
+but use it as|-|is.

+
+The generic formatters \type {a} and \type {A} convert the argument into a string
+and deals with strings, number, booleans, tables and whatever. We mostly use
+these in tracing. The lowercase variant uses single quotes, and the uppercase
+variant uses double quotes.
+
+A special one is the alignment formatter, which is a variant on the \type {s} one
+that also takes an optional positive of negative number:
+
+\startbuffer
+\startluacode
+context.start()
+context.tttf()
+context.verbatim("[[% 30<]]","xxaxx") context.par()
+context.verbatim("[[% 30<]]","xx½xx") context.par()
+context.verbatim("[[% 30>]]","xxaxx") context.par()
+context.verbatim("[[% 30>]]","xx½xx") context.par()
+context.verbatim("[[%-30<]]","xxaxx") context.par()
+context.verbatim("[[%-30<]]","xx½xx") context.par()
+context.verbatim("[[%-30>]]","xxaxx") context.par()
+context.verbatim("[[%-30>]]","xx½xx") context.par()
+context.stop()
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+There are two more formatters plugged in: \type {!xml!} and \type {!tex!}. These
+are best demonstrated with an example:
+
+\starttyping
+local xf = formatter["xml escaped: %!xml!"]
+local xr = formatter["tex escaped: %!tex!"]
+
+print(xf("x > 1 && x < 10"))
+print(xt("this will cost me $123.00 at least"))
+\stoptyping
+
+weird, this fails when cld-verbatim is there as part of the big thing:
+catcodetable 4 suddenly lacks the comment being a other
+
+The \type {context} command uses the formatter so one can say:
+
+\startbuffer
+\startluacode
+context("first some xml: %!xml!, and now some %!tex!",
+    "x > 1 && x < 10", "this will cost me $123.00 at least")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This renders as follows:
+
+\blank \getbuffer \blank
+
+You can extend the formatter but we advise you not to do that unless you're sure
+what you're doing. You never know what \CONTEXT\ itself might add for its own
+benefit.
+
+However, you can define your own formatter and add to that without interference.
+In fact, the main formatter is just defined that way. This is how it works:
+
+\startbuffer[definition]
+local MyFormatter = utilities.strings.formatters.new()
+
+utilities.strings.formatters.add (
+    MyFormatter,
+    "upper",
+    "global.string.upper(%s)"
+)
+\stopbuffer
+
+\typebuffer[definition]
+
+Now you can use this one as:
+
+\startbuffer[usage]
+context.bold(MyFormatter["It's %s or %!upper!."]("this","that"))
+\stopbuffer
+
+\typebuffer[usage]
+
+\blank \ctxluabuffer[definition,usage] \blank
+
+Because we're running inside \CONTEXT, a better definition would be this:
+
+\startbuffer
+local MyFormatter = utilities.strings.formatters.new()
+
+utilities.strings.formatters.add (
+    MyFormatter,
+    "uc",
+    "myupper(%s)",
+ -- "local myupper = global.characters.upper"
+    { myupper = global.characters.upper }
+)
+
+utilities.strings.formatters.add (
+    MyFormatter,
+    "lc",
+    "mylower(%s)",
+ -- "local mylower = global.characters.lower"
+    { mylower = global.characters.lower }
+)
+
+utilities.strings.formatters.add (
+    MyFormatter,
+    "sh",
+    "myshaped(%s)",
+ -- "local myshaped = global.characters.shaped"
+    { myshaped = global.characters.shaped }
+)
+
+context(MyFormatter["Uppercased: %!uc!"]("ÀÁÂÃÄÅàáâãäå"))
+context.par()
+context(MyFormatter["Lowercased: %!lc!"]("ÀÁÂÃÄÅàáâãäå"))
+context.par()
+context(MyFormatter["Reduced: %!sh!"]("ÀÁÂÃÄÅàáâãäå"))
+\stopbuffer
+
+\typebuffer
+
+The last arguments creates shortcuts. As expected we get:
+
+\blank \ctxluabuffer \blank
+
+Of course you can also apply the casing functions directly so in practice you
+shouldn't use formatters without need. Among the advantages of using formatters
+are:
+
+\startitemize[packed]
+\startitem They provide a level of abstraction. \stopitem
+\startitem They can replace multiple calls to \type {\context}. \stopitem
+\startitem Sometimes they make source code look better. \stopitem
+\startitem Using them is often more efficient and faster. \stopitem
+\stopitemize
+
+The last argument might sound strange but considering the overhead involved in
+the \type {context} (related) functions, doing more in one step has benefits.
+Also, formatters are implemented quite efficiently, so their overhead can be
+neglected.
+
+In the examples you see that a formatter extension is itself a template.
+
+\startbuffer
+local FakeXML = utilities.strings.formatters.new()
+
+utilities.strings.formatters.add(FakeXML,"b",[["<" ..%s..">" ]])
+utilities.strings.formatters.add(FakeXML,"e",[["</"..%s..">" ]])
+utilities.strings.formatters.add(FakeXML,"n",[["<" ..%s.."/>"]])
+
+context(FakeXML["It looks like %!b!xml%!e! doesn't it?"]("it","it"))
+\stopbuffer
+
+\typebuffer
+
+This gives: \ctxluabuffer. Of course we could go over the top here:
+
+\startbuffer
+local FakeXML = utilities.strings.formatters.new()
+
+local stack = { }
+
+function document.f_b(s)
+    table.insert(stack,s)
+    return "<" .. s .. ">"
+end
+
+function document.f_e()
+    return "</" .. table.remove(stack) .. ">"
+end
+
+utilities.strings.formatters.add(FakeXML,"b",[[global.document.f_b(%s)]])
+utilities.strings.formatters.add(FakeXML,"e",[[global.document.f_e()]])
+
+context(FakeXML["It looks like %1!b!xml%0!e! doesn't it?"]("it"))
+\stopbuffer
+
+\typebuffer
+
+This gives: \ctxluabuffer. Such a template look horrible, although it's not too
+far from the regular format syntax: just compare \type {%1f} with \type {%1!e!}.
+The zero trick permits us to inject information that we've put on the stack. As
+this kind of duplicate usage might occur most, a better solution is available:
+
+\startbuffer
+local FakeXML = utilities.strings.formatters.new()
+
+utilities.strings.formatters.add(FakeXML,"b",[["<"  .. %s .. ">"]])
+utilities.strings.formatters.add(FakeXML,"e",[["</" .. %s .. ">"]])
+
+context(FakeXML["It looks like %!b!xml%-1!e! doesn't it?"]("it"))
+\stopbuffer
+
+\typebuffer
+
+We get: \ctxluabuffer. Anyhow, in most cases you will never feel the need for
+such hackery and the regular formatter works fine. Adding this extension
+mechanism was rather trivial and it doesn't influence the performance.
+
+In \CONTEXT\ we have a few more extensions:
+
+\starttyping
+utilities.strings.formatters.add (
+    strings.formatters, "unichr",
+    [["U+" .. format("%%05X",%s) .. " (" .. utfchar(%s) .. ")"]]
+)
+
+utilities.strings.formatters.add (
+    strings.formatters, "chruni",
+    [[utfchar(%s) .. " (U+" .. format("%%05X",%s) .. ")"]]
+)
+\stoptyping
+
+This one is used in messages:
+
+\startbuffer
+context("Missing character %!chruni! in font.",234) context.par()
+context("Missing character %!unichr! in font.",234)
+\stopbuffer
+
+\typebuffer
+
+This shows up as:
+
+\blank \getbuffer \blank
+
+If you look closely to the definition, you will notice that we use \type {%s}
+twice. This is a feature of the definer function: if only one argument is
+picked up (which is default) then the replacement format can use that two
+times. Because we use a format in the constructor, we need to escape the
+percent sign there.
+
+\stopsummary
+
+\startsummary[title={strip}]
+
+This function removes any leading and trailing whitespace characters.
+
+\starttyping

+\stoptyping

+\ShowLuaExampleThree {string} {strip} {" lua + tex = luatex "}
+
+\stopsummary
+
+\startsummary[title={split splitlines checkedsplit}]
+
+The line splitter is a special case of the generic splitter. The \type {split}

+{checkedsplit} function removes empty substrings.
+
+\starttyping
+local t = string.split        (str, pattern)

+\stopsummary

+\startsummary[title={quoted unquoted}]
+
+You will hardly need these functions. The \type {quoted} function can normally be
+avoided using the \type {format} pattern \type {%q}. The \type {unquoted}
+function removes single or double quotes but only when the string starts and ends
+with the same quote.
+

+\stopsummary
+
+\startsummary[title={count}]
+
+The function \type {count} returns the number of times that a given pattern
+occurs. Beware: if you want to deal with \UTF\ strings, you need the variant that
+sits in the \type {lpeg} namespace.
+
+\starttyping

+\startsummary[title={limit}]

+\startsummary[title={escapedpattern topattern}]

+
+\starttyping
+local e = escapedpattern(str, simple)
+local p = topattern     (str, lowercase, strict)
+\stoptyping
+
+The simple variant does less escaping (only \type {-.?*} and is for instance used
+in wildcard patterns when globbing directories. The \type {topattern} function

+We used to have the \type {slunicode} library available but as most of it is not

+
+Programming languages use \ASCII\ mostly so there each characters takes one byte.
+In \CJK\ scripts however, you end up with much longer sequences. If you ever did

+
+In the \type {number} namespace we collect some helpers that deal with numbers as
+well as bits. Starting with \LUA\ 5.2 a library \type {bit32} is but the language
+itself doesn't provide for them via operators: the library uses functions to
+manipulate numbers upto 2\high{32}. In the latest \LUATEX\ you can use the new

+%
+% \startsummary[title={hasbit setbit clearbit}]

+% if that number already has that bit set. Instead we use:

+\startsection[title=\LPEG\ patterns]
+
+For \LUATEX\ and \CONTEXT\ \MKIV\ the \type {lpeg} library came at the right
+moment as we can use it in lots of places. An in|-|depth discussion makes no
+sense as it's easier to look into \type {l-lpeg.lua}, so we stick to an overview.
+\footnote {If you search the web for \type {lua lpeg} you will end up at the
+official documentation and tutorial.} Most functions return an \type {lpeg}
+object that can be used in a match. In time critical situations it's more
+efficient to use the match on a predefined pattern that to create the pattern new
+each time. Patterns are cached so there is no penalty in predefining a pattern.
+So, in the following example, the \type {splitter} that splits at the asterisk
+will only be created once.
+
+\starttyping
+local splitter_1 = lpeg.splitat("*")
+local splitter_2 = lpeg.splitat("*")

+local n, m = lpeg.match(splitter_2,"2*4")
+\stoptyping
+
+\startsummary[title={[lua] match print P R S V C Cc Cs ...}]

+
+\starttyping
+local P, R, C, Ct = lpeg.P, lpeg.R, lpeg.C, lpeg.Ct

+The \type {io} library is extended with a couple of functions as well and

+
+The IO library deals with in- and output from the console and
+files.
+
+\starttyping
+local f  = io.open(filename)
+\stoptyping
+
+When the call succeeds \type {f} is a file object. You close this file
+with:
+
+\starttyping
+f:close()
+\stoptyping
+
+Reading from a file is done with \type {f:read(...)} and writing to a file with
+\type {f:write(...)}. In order to write to a file, when opening a second argument
+has to be given, often \type {wb} for writing (binary) data. Although there are
+more efficient ways, you can use the \type {f:lines()} iterator to process a file
+line by line.
+
+You can open a process with \type {io.popen} but dealing with this one depends a
+bit on the operating system.

+\startsummary[title={loaddata savedata}]
+
+These two functions save you some programming. The first function loads a whole
+file in a string. By default the file is loaded in binary mode, but when the
+second argument is \type {true}, some interpretation takes place (for instance
+line endings). In practice the second argument can best be left alone.
+
+\starttyping
+io.loaddata(filename,textmode)
+\stoptyping
+
+Saving the data is done with:
+
+\starttyping
+io.savedata(filename,str)
+io.savedata(filename,tab,joiner)
+\stoptyping
+
+When a table is given, you can optionally specify a string that
+ends up between the elements that make the table.

+
+These three function don't need much comment.

+\stopsummary
+
+\startsummary[title={characters bytes readnumber readstring}]
+
+When I wrote the icc profile loader, I needed a few helpers for reading strings
+of a certain length and numbers of a given width. Both accept five values of
+\type {n}: \type {-4}, \type {-2}, \type {1}, \type {2} and \type {4} where the
+negative values swap the characters or bytes.
+
+\starttyping
+io.characters(f,n) --
+io.bytes(f,n)
+\stoptyping
+
+The function \type {readnumber} accepts five sizes: \type {1}, \type {2}, \type
+{4}, \type {8}, \type {12}. The string function handles any size and strings zero
+bytes from the string.
+
+\starttyping
+io.readnumber(f,size)
+io.readstring(f,size)
+\stoptyping
+
+Optionally you can give the position where the reading has to start:

+\starttyping
+io.readnumber(f,position,size)
+io.readstring(f,position,size)
+\stoptyping
+
+\stopsummary
+
+\startsummary[title={ask}]

+local filename = file.replacesuffix(filename, suffix)
+\stoptyping
+
+The first one adds a suffix unless one is present. When \type {criterium} is
+\type {true} no checking is done and the suffix is always appended. The second

+\stoptyping
+
+The \type {drive} variable is empty on operating systems other than \MSWINDOWS.
+Such components are joined with the function:

+\starttyping
+file.join(...)
+\stoptyping
+
+The given snippets are joined using the \type {/} as this is

+
+The reverse operation is done with:

+% not yet documented: dir.collectpattern(path,patt,recurse,result) -- collects tree
+
+The \type {glob} function collects files with names that match a given pattern.
+The pattern can have wildcards: \type {*} (oen of more characters), \type {?}
+(one character) or \type {**} (one or more directories). You can pass the

+
+\starttyping

+
+The target is optional and often you end up with simple calls like:

+
+The \type {globfiles} function collects matches in a table that is returned at

+\startsection[title={Parameters}]
+
+Right from the start \CONTEXT\ came with several user interfaces. As a

+\stoptyping
+
+and the \LUA\ call:
+
+\starttyping
+context.setupsomething { key = value }
+\stoptyping
+
+are equivalent. However, all keys at the \TEX\ end eventually become English, but
+the values are unchanged. This means that when you code in \LUA\ you should use
+English keys and when dealing with assigned values later on, you need to
+translate them of compare with translations (which is easier). This is why in the
+\CONTEXT\ code you will see:

+\starttyping
+if somevalue == interfaces.variables.yes then
+  ...
+end
+\stoptyping
+
+instead of:
+
+\starttyping
+if somevalue == "yes" then
+  ...
+end
+\stoptyping
+
+\stopsection
+
+\startsection[title={User interfacing}]
+
+Unless this is somehow inhibited, users can write their own macros and this is
+done in the \TEX\ language. Passing data to macros is possible and looks like
+this:
+
+\starttyping
+\def\test#1#2{.. #1 .. #2 .. }      \test{a}{b}
+\def\test[#1]#2{.. #1 .. #2 .. }    \test[a]{b}
+\stoptyping
+
+Here \type {#1} and \type {#2} represent an argument and there can be at most 9
+of them. The \type{[]} are delimiters and you can delimit in many ways so the
+following is also right:
+
+\starttyping
+\def\test(#1><#2){.. #1 .. #2 .. }  \test(a><b)
+\stoptyping
+
+Macro packages might provide helper macros that for instance take care of
+optional arguments, so that we can use calls like:
+
+\starttyping
+\test[1,2,3][a=1,b=2,c=3]{whatever}
+\stoptyping
+
+and alike. If you are familiar with the \CONTEXT\ syntax you know that we use
+this syntax all over the place.
+
+If you want to write a macro that calls out to \LUA\ and handles things at that
+end, you might want to avoid defining the macro itself and this is possible.
+
+\startbuffer
+\startluacode
+function test(opt_1, opt_2, arg_1)
+    context.startnarrower()
+    context("options 1: %s",interfaces.tolist(opt_1))
+    context.par()
+    context("options 2: %s",interfaces.tolist(opt_2))
+    context.par()
+    context("argument 1: %s",arg_1)
+    context.stopnarrower()
+end
+
+interfaces.definecommand {
+    name = "test",
+    arguments = {
+        { "option", "list" },
+        { "option", "hash" },
+        { "content", "string" },
+    },
+    macro = test,
+}
+\stopluacode
+
+test: \test[1][a=3]{whatever}
+\stopbuffer
+
+An example of a definition and usage at the \LUA\ end is:
+
+\typebuffer
+
+The call gives:
+
+\startpacked
+\getbuffer
+\stoppacked
+
+\startbuffer
+\startluacode
+local function startmore(opt_1)
+    context.startnarrower()
+    context("start more, options: %s",interfaces.tolist(opt_1))
+    context.startnarrower()
+end
+
+local function stopmore(opt_1)
+    context.stopnarrower()
+    context("stop more, options: %s",interfaces.tolist(opt_1))
+    context.stopnarrower()
+end
+
+interfaces.definecommand ( "more", {
+    environment = true,
+    arguments = {
+        { "option", "list" },
+    },
+    starter = startmore,
+    stopper = stopmore,
+} )
+\stopluacode
+
+more: \startmore[1] one \startmore[2] two \stopmore one \stopmore
+\stopbuffer
+
+If you want to to define an environment (i.e.\ a \type {start}||\type {stop}
+pair, it looks as follows:
+
+\typebuffer
+
+This gives:
+
+\startpacked
+\getbuffer
+\stoppacked
+
+The arguments are know in both \type {startmore} and \type {stopmore} and nesting
+is handled automatically.
+
+\stopsection
+
+\startsection[title=Looking inside]
+
+If needed you can access the body of a macro. Take for instance:
+
+\startbuffer
+\def\TestA{A}
+\def\TestB{\def\TestC{c}}
+\def\TestC{C}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The following example demonsttaies how we can look inside these macros. You need
+to be aware of the fact that the whole blob of \LUA\ codes is finished before we
+return to \TEX, so when we pipe the meaning of \type {TestB} back to \TEX\ it
+only gets expanded afterwards. We can use a function to get back to \LUA. It's
+only then that the meaning of \type {testC} is changed by the (piped) expansion
+of \type {TestB}.
+
+\startbuffer
+\startluacode
+context(tokens.getters.macro("TestA"))
+context(tokens.getters.macro("TestB"))
+context(tokens.getters.macro("TestC"))
+tokens.setters.macro("TestA","a")
+context(tokens.getters.macro("TestA"))
+context(function()
+    context(tokens.getters.macro("TestA"))
+    context(tokens.getters.macro("TestB"))
+    context(tokens.getters.macro("TestC"))
+end)
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Here is another example:
+
+\startbuffer
+\startluacode
+if tokens.getters.macro("fontstyle") == "rm" then
+    context("serif")
+else
+    context("unknown")
+end
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Of course this assumes that you have some knowledge of the \CONTEXT\ internals.

+
+\startsection[title=Why we need them]
+
+\index{functions}
+
+In a previous chapter we introduced functions as arguments. At first sight this
+feature looks strange but you need to keep in mind that a call to a \type
+{context} function has no direct consequences. It generates \TEX\ code that is
+executed after the current \LUA\ chunk ends and control is passed back to \TEX.
+Take the following code:
+
+\startbuffer
+context.framed( {
+    frame = "on",
+    offset = "5mm",
+    align = "middle"
+  },
+  context.input("knuth")
+)
+\stopbuffer
+
+\typebuffer
+
+We call the function \type {framed} but before the function body is executed, the
+arguments get evaluated. This means that \type {input} gets processed before
+\type {framed} gets done. As a result there is no second argument to \type
+{framed} and no content gets passed: an error is reported. This is why we need
+the indirect call:
+
+\startbuffer
+context.framed( {
+    frame = "on",
+    align = "middle"
+  },
+  function() context.input("knuth") end
+)
+\stopbuffer
+
+\typebuffer
+
+This way we get what we want:
+
+\startlinecorrection
+\ctxluabuffer
+\stoplinecorrection
+
+The function is delayed till the \type {framed} command is executed. If your
+applications use such calls a lot, you can of course encapsulate this ugliness:
+
+\starttyping
+mycommands = mycommands or { }
+
+function mycommands.framed_input(filename)
+  context.framed( {
+    frame = "on",
+    align = "middle"
+  },
+  function() context.input(filename) end
+end
+
+mycommands.framed_input("knuth")
+\stoptyping
+
+Of course you can nest function calls:
+
+\starttyping
+context.placefigure(
+  "caption",
+  function()
+    context.framed( {
+      frame = "on",
+      align = "middle"
+    },
+      function() context.input("knuth") end
+    )
+  end
+)
+\stoptyping
+
+Or you can use a more indirect method:
+
+\starttyping
+function text()
+  context.framed( {
+      frame = "on",
+      align = "middle"
+    },
+    function() context.input("knuth") end
+  )
+end
+
+context.placefigure(
+  "none",
+  function() text() end
+)
+\stoptyping
+
+You can develop your own style and libraries just like you do with regular \LUA\
+code. Browsing the already written code can give you some ideas.
+
+\stopsection
+
+\startsection[title=How we can avoid them]
+
+\index{delaying}
+\index{nesting}
+
+As many nested functions can obscure the code rather quickly, there is an
+alternative. In the following examples we use \type {test}:
+
+\startbuffer
+\def\test#1{[#1]}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+context.test("test 1 ",context("test 2a")," test 3")
+\stopbuffer
+
+\typebuffer
+
+This gives: \ctxluabuffer. As you can see, the second argument is executed before
+the encapsulating call to \type {test}. So, we should have packed it into a
+function but here is an alternative:
+
+\startbuffer
+context.test("test 1 ",context.delayed("test 2a")," test 3")
+\stopbuffer
+
+\typebuffer
+
+Now we get: \ctxluabuffer. We can also delay functions themselves,
+look at this:
+
+\startbuffer
+context.test("test 1 ",context.delayed.test("test 2b")," test 3")
+\stopbuffer
+
+\typebuffer
+
+The result is: \ctxluabuffer. This feature also conveniently permits the use of
+temporary variables, as in:
+
+\starttyping
+local f = context.delayed.test("test 2c")
+context("before ",f," after")
+\stoptyping
+
+Of course you can limit the amount of keystrokes even more by
+creating a shortcut:
+
+\starttyping
+local delayed = context.delayed
+
+context.test("test 1 ",delayed.test("test 2")," test 3")
+context.test("test 4 ",delayed.test("test 5")," test 6")
+\stoptyping
+
+So, if you want you can produce rather readable code and readability of code is
+one of the reasons why \LUA\ was chosen in the first place. This is a good
+example of why coding in \TEX\ makes sense as it looks more intuitive:
+
+\starttyping
+\test{test 1 \test{test 2} test 3}
+\test{test 4 \test{test 5} test 6}
+\stoptyping
+
+There is also another mechanism available. In the next example the second
+argument is actually a string.
+
+\starttyping
+local nested = context.nested
+
+context.test("test 8",nested.test("test 9"),"test 10")
+\stoptyping
+
+There is a pitfall here: a nested context command needs to be flushed explicitly,
+so in the case of:
+
+\starttyping
+context.nested.test("test 9")
+\stoptyping
+
+a string is created but nothing ends up at the \TEX\ end. Flushing is up to you.
+Beware: \type {nested} only works with the regular \CONTEXT\ catcode regime.
+
+\stopsection
+
+\startsection[title=Trial typesetting]
+
+\index {prerolls}
+\index {trial typesetting}
+
+Some typesetting mechanisms demand a preroll. For instance, when determining the
+most optimal way to analyse and therefore typeset a table, it is necessary to
+typeset the content of cells first. Inside \CONTEXT\ there is a state tagged
+\quote {trial typesetting} which signals other mechanisms that for instance
+counters should not be incremented more than once.
+
+Normally you don't need to worry about these issues, but when writing the code
+that implements the \LUA\ interface to \CONTEXT, it definitely had to be taken
+into account as we either or not can free cached (nested) functions.
+
+You can influence this caching to some extend. If you say
+
+\starttyping
+function()
+  context("whatever")
+end
+\stoptyping
+
+the function will be removed from the cache when \CONTEXT\ is not in the trial
+typesetting state. You can prevent removal of a function by returning \type
+{true}, as in:
+
+\starttyping
+function()
+  context("whatever")
+  return true
+end
+\stoptyping
+
+Whenever you run into a situation that you don't get the outcome that you expect,
+you can consider returning \type {true}. However, keep in mind that it will take
+more memory, something that only matters on big runs. You can force flushing the
+whole cache by:
+
+\starttyping
+context.restart()
+\stoptyping
+
+An example of an occasion where you need to keep the function available is in
+repeated content, for instance in headers and footers.
+
+\starttyping
+context.setupheadertexts {
+  function()
+    context.pagenumber()
+    return true
+  end
+}
+\stoptyping
+
+Of course it is not needed when you use the following method:
+
+\starttyping
+context.pagenumber("pagenumber")
+\stoptyping
+
+Because here \CONTEXT\ itself deals with the content driven by the keyword \type
+{pagenumber}.
+
+\stopsection
+
+\startsection[title=Steppers]
+
+The \type {context} commands are accumulated within a \type {\ctxlua} call and
+only after the call is finished, control is back at the \TEX\ end. Sometimes you
+want (in your \LUA\ code) to go on and pretend that you jump out to \TEX\ for a
+moment, but come back to where you left. The stepper mechanism permits this.
+
+A not so practical but nevertheless illustrative example is the following:
+
+\startbuffer
+\startluacode
+  context.stepwise (function()
+    context.startitemize()
+       context.startitem()
+         context.step("BEFORE 1")
+       context.stopitem()
+       context.step("\\setbox0\\hbox{!!!!}")
+       context.startitem()
+         context.step("%p",tex.getbox(0).width)
+       context.stopitem()
+       context.startitem()
+         context.step("BEFORE 2")
+       context.stopitem()
+       context.step("\\setbox2\\hbox{????}")
+       context.startitem()
+         context.step("%p",tex.getbox(2).width)
+       context.startitem()
+         context.step("BEFORE 3")
+       context.stopitem()
+       context.startitem()
+         context.step("\\copy0\\copy2")
+       context.stopitem()
+       context.startitem()
+         context.step("BEFORE 4")
+         context.startitemize()
+           context.stepwise (function()
+             context.step("\\bgroup")
+             context.step("\\setbox0\\hbox{>>>>}")
+             context.startitem()
+               context.step("%p",tex.getbox(0).width)
+             context.stopitem()
+             context.step("\\setbox2\\hbox{<<<<}")
+             context.startitem()
+               context.step("%p",tex.getbox(2).width)
+             context.stopitem()
+             context.startitem()
+               context.step("\\copy0\\copy2")
+             context.stopitem()
+             context.startitem()
+               context.step("\\copy0\\copy2")
+             context.stopitem()
+             context.step("\\egroup")
+           end)
+         context.stopitemize()
+       context.stopitem()
+       context.startitem()
+         context.step("AFTER 1\\par")
+       context.stopitem()
+       context.startitem()
+         context.step("\\copy0\\copy2\\par")
+       context.stopitem()
+       context.startitem()
+         context.step("\\copy0\\copy2\\par")
+       context.stopitem()
+       context.startitem()
+         context.step("AFTER 2\\par")
+       context.stopitem()
+       context.startitem()
+         context.step("\\copy0\\copy2\\par")
+       context.stopitem()
+       context.startitem()
+         context.step("\\copy0\\copy2\\par")
+       context.stopitem()
+     context.stopitemize()
+end)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This gives an (ugly) itemize with a nested one:
+
+\getbuffer
+
+As you can see in the code, the \type {step} call accepts multiple arguments, but
+when more than one argument is given the first one is treated as a formatter.

+\startchapter[title=Nice to know]
+
+\startsection[title=Introduction]
+
+As we like to abstract interfaces it is no surprise that \CONTEXT\ and
+therefore it's \LUA\ libraries come with all kind of helpers. In this
+chapter I will explain a few of them. Feel free to remind of adding more
+here.
+
+\stopsection
+
+\startsection[title=Templates]
+
+{\em Eventually we will move this to the utilities section.}
+
+When dealing with data from tables or when order matters it can be handy
+to abstract the actual data from the way it is dealt with. For this we
+provide a template mechanism. The following example demonstrate its use.
+
+\startbuffer
+require("util-ran") -- needed for this example
+
+local preamble = [[|l|l|c|]]
+local template = [[\NC %initials% \NC %surname% \NC %length% \NC \NR]]
+
+context.starttabulate { preamble }
+    for i=1,10 do
+        local row = utilities.templates.replace(template, {
+            surname  = utilities.randomizers.surname(5,10),
+            initials = utilities.randomizers.initials(1,3),
+            length   = string.format("%0.2f",math.random(140,195)),
+        })
+        context(row)
+    end
+context.stoptabulate()
+\stopbuffer
+
+\typebuffer
+
+This renders a table with random entries:
+
+\ctxluabuffer
+
+The nice thing is that when we change the order of the columns, we don't need to
+change the table builder.
+
+\starttyping
+local preamble = [[|c|l|l|]]
+local template = [[\NC %length% \NC %initials% \NC %surname% \NC \NR]]
+\stoptyping
+
+The \type {replace} function takes a few more arguments. There are also a some
+more replacement options.
+
+\starttyping
+replace("test '%[x]%' test",{ x = [[a 'x'  a]] }))
+replace("test '%[x]%' test",{ x = true }))
+replace("test '%[x]%' test",{ x = [[a 'x'  a]], y = "oeps" },'sql'))
+replace("test '%[x]%' test",{ x = [[a '%y%'  a]], y = "oeps" },'sql',true))
+replace([[test %[x]% test]],{ x = [[a "x"  a]]}))
+replace([[test %(x)% test]],{ x = [[a "x"  a]]}))
+\stoptyping
+
+The first argument is the template and the second one a table with mappings from
+keys to values. The third argument can be used to inform the replace mechanism
+what string escaping has to happen. The last argument triggers recursive
+replacement. The above calls result in the following strings:
+
+\starttyping
+test 'a 'x' \127 a' test
+test 'true' test
+test 'a ''x''  a' test
+test 'a ''oeps''  a' test
+test a \"x\" \127 a test
+test "a \"x\" \127 a" test
+\stoptyping
+
+These examples demonstrate that by adding a pair of square brackets we get
+escaped strings. When using parenthesis the quotes get added automatically. This
+is somewhat faster in case when \LUA\ is the target, but in practice it is not
+that noticeable.
+
+% replace(str,mapping,how,recurse)
+
+\stopsection
+
+\startsection [title=Extending]
+
+Instead of extending tex endlessly we can also define our own extensions. Here
+is an example. When you want to manipulate a box at the \LUA\ end you have the
+problem that the following will not always work out well:
+
+\starttyping
+local b = tex.getbox(0)
+-- mess around with b
+tex.setbox(0,b)
+\stoptyping
+
+So we end up with:
+
+\starttyping
+local b = node.copy_list(tex.getbox(0))
+-- mess around with b
+tex.setbox(0,b)
+\stoptyping
+
+The reason is that at the \TEX\ end grouping plays a role which means that values
+are saved and restored. However, there is a save way out by defining a function
+that cheats a bit:
+

+Now we can say:

+\starttyping
+local b = tex.takebox(0)
+-- mess around with b
+tex.setbox(b)
+\stoptyping
+
+In this case we first get the box content and then let \TEX\ do some housekeeping.
+But, because we only keep the list node (which we copied) in the register the
+overhead of copying a whole list is gone.

+\startsection[title=Appetizer]
+
+Before we give some more examples, we will have a look at the way the title page
+is made. This way you get an idea what more is coming.
+
+\typefile {cld-mkiv-simple-titlepage.cld}
+
+This does not look that bad, does it? Of course in pure \TEX\ code it looks
+mostly the same but loops and calculations feel a bit more natural in \LUA\ then
+in \TEX. The result is shown in \in {figure} [fig:cover]. The actual cover page
+was derived from this.
+
+\startplacefigure[location=here,reference=fig:cover,title={The simplified cover page.}]
+    \doiffileexistselse {cld-mkiv-simple-titlepage.pdf} {
+        \externalfigure
+            [cld-mkiv-simple-titlepage.pdf]
+            [height=.5\textheight]
+    } {
+        \scale
+            [height=.5\textheight]
+            {\cldprocessfile{cld-mkiv-simple-titlepage.cld}}
+    }
+\stopplacefigure
+
+\stopsection
+
+\startsection[title=A few examples]
+
+As it makes most sense to use the \LUA\ interface for generated text, here is
+another example with a loop:
+
+\startbuffer
+context.startitemize { "a", "packed", "two" }
+  for i=1,10 do
+    context.startitem()
+      context("this is item %i",i)
+    context.stopitem()
+  end
+context.stopitemize()
+\stopbuffer
+
+\typebuffer
+
+\ctxluabuffer
+
+Just as you can mix \TEX\ with \XML\ and \METAPOST, you can define bits and
+pieces of a document in \LUA. Tables are good candidates:
+
+\startbuffer
+local one = {
+  align = "middle",
+  style = "type",
+}
+local two = {
+  align = "middle",
+  style = "type",
+  background = "color",
+  backgroundcolor = "darkblue",
+  foregroundcolor = "white",
+}
+local random = math.random
+context.bTABLE { framecolor = "darkblue" }
+    for i=1,10 do
+      context.bTR()
+      for i=1,20 do
+          local r = random(99)
+          context.bTD(r < 50 and one or two)
+          context("%2i",r)
+          context.eTD()
+      end
+      context.eTR()
+    end
+context.eTABLE()
+\stopbuffer
+
+\typebuffer
+
+\placetable[top][tab:random]{A table generated by \LUA.}{\ctxluabuffer}
+
+Here we see a function call to \type {context} in the most indented line. The
+first argument is a format that makes sure that we get two digits and the random
+number is substituted into this format. The result is shown in
+\in{table}[tab:random]. The line correction is ignored when we use this table as
+a float, otherwise it assures proper vertical spacing around the table. Watch how
+we define the tables \type {one} and \type {two} beforehand. This saves 198
+redundant table constructions.
+
+Not all code will look as simple as this. Consider the following:
+
+\starttyping
+context.placefigure(
+  "caption",
+  function() context.externalfigure( { "cow.pdf" } ) end
+)
+\stoptyping
+
+Here we pass an argument wrapped in a function. If we would not do that, the
+external figure would end up wrong, as arguments to functions are evaluated
+before the function that gets them (we already showed some alternative approaches
+in previous chapters). A function argument is treated as special and in this case
+the external figure ends up right. Here is another example:
+
+\startbuffer
+context.placefigure("Two cows!",function()
+  context.bTABLE()
+    context.bTR()
+      context.bTD()
+        context.externalfigure(
+            { "cow.pdf" },
+            { width = "3cm", height = "3cm" }
+        )
+      context.eTD()
+      context.bTD { align = "{lohi,middle}" }
+        context("and")
+      context.eTD()
+      context.bTD()
+        context.externalfigure(
+            { "cow.pdf" },
+            { width = "4cm", height = "3cm" }
+        )
+      context.eTD()
+    context.eTR()
+  context.eTABLE()
+end)
+\stopbuffer
+
+\typebuffer
+
+In this case the figure is not an argument so it gets flushed sequentially
+with the rest.
+
+\ctxluabuffer

+\startsection[title=Styles]
+
+Say that you want to typeset a word in a bold font. You can do
+that this way:
+
+\starttyping
+context("This is ")
+context.bold("important")
+context("!")
+\stoptyping
+
+Now imagine that you want this important word to be in red too. As we have
+a nested command, we end up with a nested call:
+
+\starttyping
+context("This is ")
+context.bold(function() context.color( { "red" }, "important") end)
+context("!")
+\stoptyping
+
+or
+
+\starttyping
+context("This is ")
+context.bold(context.delayed.color( { "red" }, "important"))
+context("!")
+\stoptyping
+
+In that case it's good to know that there is a command that combines both
+features:
+
+\starttyping
+context("This is ")
+context.style( { style = "bold", color = "red" }, "important")
+context("!")
+\stoptyping
+
+But that is still not convenient when we have to do that often. So, you can wrap
+the style switch in a function.
+
+\starttyping
+local function mycommands.important(str)
+    context.style( { style = "bold", color = "red" }, str )
+end
+
+context("This is ")
+mycommands.important( "important")
+context(", and ")
+mycommands.important( "this")
+context(" too !")
+\stoptyping
+
+Or you can setup a named style:
+
+\starttyping
+context.setupstyle( { "important" }, { style = "bold", color = "red" } )
+
+context("This is ")
+context.style( { "important" }, "important")
+context(", and ")
+context.style( { "important" }, "this")
+context(" too !")
+\stoptyping
+
+Or even define one:
+
+\starttyping
+context.definestyle( { "important" }, { style = "bold", color = "red" } )
+
+context("This is ")
+context.important("important")
+context(", and ")
+context.important("this")
+context(" too !")
+\stoptyping
+
+This last solution is especially handy for more complex cases:
+
+\startbuffer
+context.definestyle( { "important" }, { style = "bold", color = "red" } )
+
+context("This is ")
+context.startimportant()
+context.inframed("important")
+context.stopimportant()
+context(", and ")
+context.important("this")
+context(" too !")

+\startsection[title=A complete example]
+
+One day my 6 year old niece Lorien was at the office and wanted to know what I
+was doing. As I knew she was practicing arithmetic at school I wrote a quick and
+dirty script to generate sheets with exercises. The most impressive part was that
+the answers were included. It was a rather braindead bit of \LUA, written in a
+few minutes, but the weeks after I ended up running it a few more times, for her
+and her friends, every time a bit more difficult and also using different
+arithmetic. It was that script that made me decide to extend the basic cld manual
+into this more extensive document.
+
+We generate three columns of exercises. Each exercise is a row in a table. The
+last argument to the function determines if answers are shown.
+
+\starttyping
+local random = math.random
+
+local function ForLorien(n,maxa,maxb,answers)
+  context.startcolumns { n = 3 }
+  context.starttabulate { "|r|c|r|c|r|" }
+  for i=1,n do
+    local sign = random(0,1) > 0.5
+    local a, b = random(1,maxa or 99), random(1,max or maxb or 99)
+    if b > a and not sign then a, b = b, a end
+    context.NC()
+    context(a)
+    context.NC()
+    context.mathematics(sign and "+" or "-")
+    context.NC()
+    context(b)
+    context.NC()
+    context("=")
+    context.NC()
+    context(answers and (sign and a+b or a-b))
+    context.NC()
+    context.NR()
+  end
+  context.stoptabulate()
+  context.stopcolumns()
+  context.page()
+end
+\stoptyping
+
+This is a typical example of where it's more convenient to write the code in
+\LUA\ that in \TEX's macro language. As a consequence setting up the page also
+happens in \LUA:
+
+\starttyping
+context.setupbodyfont {
+  "palatino",
+  "14pt"
+}
+
+context.setuplayout {
+  backspace = "2cm",
+  topspace  = "2cm",
+  header    = "1cm",
+  footer    = "0cm",
+  height    = "middle",
+  width     = "middle",
+}
+\stoptyping
+
+This leave us to generate the document. There is a pitfall here: we need to use
+the same random number for the exercises and the answers, so we freeze and
+defrost it. Functions in the \type {commands} namespace implement functionality
+that is used at the \TEX\ end but better can be done in \LUA\ than in \TEX\ macro
+code. Of course these functions can also be used at the \LUA\ end.
+
+\starttyping
+context.starttext()
+
+  local n = 120
+
+  commands.freezerandomseed()
+
+  ForLorien(n,10,10)
+  ForLorien(n,20,20)
+  ForLorien(n,30,30)
+  ForLorien(n,40,40)
+  ForLorien(n,50,50)
+
+  commands.defrostrandomseed()
+
+  ForLorien(n,10,10,true)
+  ForLorien(n,20,20,true)
+  ForLorien(n,30,30,true)
+  ForLorien(n,40,40,true)
+  ForLorien(n,50,50,true)

+
+A few pages of the result are shown in \in {figure} [fig:lorien]. In the
+\CONTEXT\ distribution a more advanced version can be found in \type
+{s-edu-01.cld} as I was also asked to generate multiplication and table
+exercises. In the process I had to make sure that there were no duplicates on a
+page as she complained that was not good. There a set of sheets is generated
+with:
+
+\starttyping
+moduledata.educational.arithematic.generate {
+  name     = "Bram Otten",
+  fontsize = "12pt",
+  columns  = 2,

+\startsection[title=Interfacing]
+
+The fact that we can define functionality using \LUA\ code does not mean that we
+should abandon the \TEX\ interface. As an example of this we use a relatively
+simple module for typesetting morse code.\footnote {The real module is a bit
+larger and can format verbose morse.} First we create a proper namespace:
+
+\starttyping
+
+moduledata.morse = moduledata.morse or { }
+local morse      = moduledata.morse
+\stoptyping
+
+We will use a few helpers and create shortcuts for them. The first helper loops
+over each \UTF\ character in a string. The other two helpers map a character onto
+an uppercase (because morse only deals with uppercase) or onto an similar shaped
+character (because morse only has a limited character set).
+
+\starttyping
+local utfcharacters = string.utfcharacters
+local ucchars, shchars = characters.ucchars, characters.shchars
+\stoptyping
+
+The morse codes are stored in a table.
+
+\starttyping
+local codes = {
+
+    ["A"] = "·—",     ["B"] = "—···",
+    ["C"] = "—·—·",   ["D"] = "—··",
+    ["E"] = "·",      ["F"] = "··—·",
+    ["G"] = "——·",    ["H"] = "····",

+    ["O"] = "———",    ["P"] = "·——·",
+    ["Q"] = "——·—",   ["R"] = "·—·",

+    ["Ö"] = "———·",
+    ["Ø"] = "———·",
+    ["Ü"] = "··——",
+    ["ß"] = "··· ···",
+
+}
+
+morse.codes = codes
+\stoptyping
+
+As you can see, there are a few non \ASCII\ characters supported as well. There
+will never be full \UNICODE\ support simply because morse is sort of obsolete.
+Also, in order to support \UNICODE\ one could as well use the bits of \UTF\
+characters, although \unknown\ memorizing the whole \UNICODE\ table is not much
+fun.
+
+We associate a metatable index function with this mapping. That way we can not
+only conveniently deal with the casing, but also provide a fallback based on the
+shape. Once found, we store the representation so that only one lookup is needed
+per character.
+
+\starttyping
+local function resolvemorse(t,k)
+    if k then
+        local u = ucchars[k]
+        local v = rawget(t,u) or rawget(t,shchars[u]) or false
+        t[k] = v
+        return v
+    else
+        return false
+    end
+end
+
+setmetatable(codes, { __index = resolvemorse })
+\stoptyping
+
+Next comes some rendering code. As we can best do rendering at the \TEX\ end we
+just use macros.
+
+\starttyping
+local MorseBetweenWords      = context.MorseBetweenWords
+local MorseBetweenCharacters = context.MorseBetweenCharacters
+local MorseLong              = context.MorseLong

+local MorseSpace             = context.MorseSpace
+local MorseUnknown           = context.MorseUnknown
+\stoptyping
+
+The main function is not that complex. We need to keep track of spaces and
+newlines. We have a nested loop because a fallback to shape can result in
+multiple characters.
+
+\starttyping
+function morse.tomorse(str)
+    local inmorse = false
+    for s in utfcharacters(str) do
+        local m = codes[s]

+            end
+            MorseUnknown(s)
+        end
+    end
+end
+\stoptyping
+
+We use this function in two additional functions. One typesets a file, the other
+a table of available codes.
+
+\starttyping
+function morse.filetomorse(name,verbose)
+    morse.tomorse(resolvers.loadtexfile(name),verbose)
+end
+
+function morse.showtable()

+        context.NC() morse.tomorse(v,true)
+        context.NC() context.NR()
+    end
+    context.stoptabulate()
+end
+\stoptyping
+
+We're done with the \LUA\ code that we can either put in an external file or put
+in the module file. The \TEX\ file has two parts. The typesetting macros that we
+use at the \LUA\ end are defined first. These can be overloaded.
+
+\starttyping

+\def\MorseUnknown#1

+
+The dimensions are stored in macros as well. Of course we could provide a proper

+
+\starttyping
+\def\MorseWidth {0.4em}
+\def\MorseHeight{0.2em}
+\stoptyping
+
+Finally we have arrived at the macros that interface to the \LUA\ functions.

+\startsection[title=Using helpers]
+
+The next example shows a bit of \LPEG. On top of the standard functionality
+a few additional functions are provided. Let's start with a pure \TEX\
+example:
+
+\startbuffer
+\defineframed
+  [colored]
+  [foregroundcolor=red,
+   foregroundstyle=\underbar,
+   offset=.1ex,
+   location=low]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\processisolatedwords {\input ward \relax} \colored
+\stopbuffer
+
+\typebuffer \blank \getbuffer \blank
+
+Because this processor macro operates at the \TEX\ end it has some limitations.
+The content is collected in a very narrow box and from that a regular paragraph
+is constructed. It is for this reason that no color is applied: the snippets that
+end up in the box are already typeset.
+
+An alternative is to delegate the task to \LUA:
+
+\startbuffer
+\startluacode
+local function process(data)
+
+  local words = lpeg.split(lpeg.patterns.spacer,data or "")
+
+  for i=1,#words do
+    if i == 1 then
+        context.dontleavehmode()
+    else
+        context.space()
+    end
+    context.colored(words[i])
+  end
+
+end
+
+process(io.loaddata(resolvers.findfile("ward.tex")))
+\stopluacode
+\stopbuffer
+
+\typebuffer \blank \getbuffer \blank
+
+The function splits the loaded data into a table with individual words. We use a
+splitter that splits on spacing tokens. The special case for \type {i = 1} makes
+sure that we end up in horizontal mode (read: properly start a paragraph). This
+time we do get color because the typesetting is done directly. Here is an
+alternative implementation:
+
+\starttyping
+local done = false
+
+local function reset()
+    done = false
+    return true
+end
+
+local function apply(s)
+  if done then
+    context.space()
+  else
+    done = true
+    context.dontleavehmode()
+  end
+  context.colored(s)
+end
+
+local splitter = lpeg.P(reset)
+               * lpeg.splitter(lpeg.patterns.spacer,apply)
+
+local function process(data)
+  lpeg.match(splitter,data)
+end
+\stoptyping
+
+This version is more efficient as it does not create an intermediate table. The
+next one is comaprable:
+
+\starttyping
+local function apply(s)
+  context.colored("%s ",s)
+end
+
+local splitter lpeg.splitter(lpeg.patterns.spacer,apply)
+
+local function process(data)
+  context.dontleavevmode()
+  lpeg.match(splitter,data)
+  context.removeunwantedspaces()
+end
+\stoptyping
+
+\stopsection
+
+\startsection[title=Formatters]
+
+Sometimes can save a bit of work by using formatters. By default, the \type {context}
+command, when called directly, applies a given formatter. But when called as table
+this feature is lost because then we want to process non|-|strings as well. The next
+example shows a way out:
+
+\startbuffer
+context("the current emwidth is %p",\number\emwidth)
+context.par()
+context.formatted("the current emwidth is %p",\number\emwidth)
+context.par()
+context.bold(string.formatters["the current emwidth is %p"](\number\emwidth))
+context.par()
+context.formatted.bold("the current emwidth is %p",\number\emwidth)
+\stopbuffer
+
+The last one is the most interesting one here: in the subnamespace \type
+{formatted} (watch the \type {d}) a format specification with extra arguments is
+expected.

+
+\starttyping
+context.runfile("somefile.cld")
+\stoptyping
+
+Another useful command is:

+\stopsection
+
+\startsection[title=Overloads]
+
+A few macros have special functions (overloads) at the \LUA\ end. One of them is
+\type {\char}. The function makes sure that the characters ends up right. The
+same is true for \type {\chardef}. So, you don't need to mess around with \type
+{\relax} or trailing spaces as you would do at the \TEX\ end in order to tell the
+scanner to stop looking ahead.
+
+\starttyping
+context.char(123)

+% added and extended in sync with an article about a generic 'execute'
+% feature
+
+We already mentioned the stepper as a very special trick so let's give
+some more explanation here. When you run the following code:
+
+\setbox0\emptybox
+
+\starttyping
+\startluacode
+  context.startitemize()
+    context.startitem()
+      context("BEFORE 1")
+    context.stopitem()
+    context("\\setbox0\\hbox{!!!!}")
+    context.startitem()
+      context("%p",tex.getbox(0).width)
+    context.stopitem()
+  context.stopitemize()
+\stopluacode
+\stoptyping
+
+You get a message like:
+
+\starttyping
+[ctxlua]:8: attempt to index a nil value
+...
+10             context("\\setbox0\\hbox{!!!!}")
+11             context.startitem()
+12 >>              context("%p",tex.getbox(0).width)
+...
+\stoptyping
+
+due to the fact that the box is still void. All that the \CONTEXT\ commands feed
+into \TEX\ happens when the code snippet has finished. You can however run a
+snippet of code the following way:
+
+\startbuffer
+\startluacode
+  context.stepwise (function()
+    context.startitemize()
+      context.startitem()
+        context.step("BEFORE 1")
+      context.stopitem()
+      context.step("\\setbox0\\hbox{!!!!}")
+      context.startitem()
+        context.step("%p",tex.getbox(0).width)
+      context.stopitem()
+    context.stopitemize()
+  end)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+and get:
+
+\getbuffer
+
+A more extensive example is:
+
+\startbuffer
+\startluacode
+  context.stepwise (function()
+    context.startitemize()
+      context.startitem()
+        context.step("BEFORE 1")

+      context.stopitem()
+      context.startitem()
+        context.step("BEFORE 2")
+      context.stopitem()
+      context.step("\\setbox2\\hbox{????}")
+      context.startitem()
+        context.step("%p",tex.getbox(2).width)
+      context.startitem()
+        context.step("BEFORE 3")
+      context.stopitem()
+      context.startitem()
+        context.step("\\copy0\\copy2")
+      context.stopitem()
+      context.startitem()
+        context.step("BEFORE 4")
+        context.startitemize()
+          context.stepwise (function()
+            context.step("\\bgroup")
+            context.step("\\setbox0\\hbox{>>>>}")
+            context.startitem()
+              context.step("%p",tex.getbox(0).width)
+            context.stopitem()
+            context.step("\\setbox2\\hbox{<<<<}")

+            context.startitem()
+              context.step("\\copy0\\copy2")
+            context.stopitem()
+            context.step("\\egroup")
+          end)
+        context.stopitemize()
+      context.stopitem()
+      context.startitem()
+        context.step("AFTER 1\\par")
+      context.stopitem()
+      context.startitem()
+        context.step("\\copy0\\copy2\\par")
+      context.stopitem()
+      context.startitem()
+        context.step("\\copy0\\copy2\\par")
+      context.stopitem()
+      context.startitem()
+        context.step("AFTER 2\\par")
+      context.stopitem()
+      context.startitem()
+        context.step("\\copy0\\copy2\\par")
+      context.stopitem()
+      context.startitem()
+        context.step("\\copy0\\copy2\\par")
+      context.stopitem()
+    context.stopitemize()
+  end)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+which gives:
+
+\getbuffer
+
+A step returns control to \TEX\ immediately and after the \TEX\ code that it
+feeds back is expanded, returns to \LUA. There are some limitations due to the
+input stack but normally that is no real issue.
+
+You can run the following code:
+
+\starttyping
+\definenumber[LineCounter][way=bypage]
+\starttext
+\startluacode
+for i=1,2000 do
+    context.incrementnumber { "LineCounter" }
+    context.getnumber { "LineCounter" }
+    context.par()
+end
+\stopluacode
+\stoptext
+\stoptyping
+
+You will notice however that the number is not right on each page. This is
+because \TEX\ doesn't know yet that there is no room on the page. The next will
+work better:
+
+\starttyping
+\definenumber[LineCounter][way=bypage]
+\starttext
+\startluacode
+context.stepwise(function()
+    for i=1,2000 do
+        context.testpage { 0 }
+        context.incrementnumber { "LineCounter" }
+        context.getnumber { "LineCounter" }
+        context.par()
+        context.step()
+    end
+end)
+\stopluacode
+\stoptext
+\starttyping
+
+Instead of the \type {testpage} function you can also play directly with
+registers, like:
+
+\starttyping
+if tex.pagegtotal + tex.count.lineheight > tex.pagetotal then
+\starttyping
+
+but often an already defined helper does a better job. Of course you will
+probably never need this kind of hacks anyway, if only because much more is going
+on and there are better ways then.

+\startchapter[title=A sort of summary]
+
+In this chapter we summarize the functionality provided by the \type {context}
+namespace. We repeat some of what has been explained in other chapter so that in
+fact you can start with this summary.
+
+If you have read this manual (or seen code) you know that you can access all the
+core commands using this namespace:
+
+\starttyping
+context.somecommand("some argument")
+context["somecommand"]("some argument")
+\stoptyping
+
+These calls will eventually expand \type {\somecommand} with the given argument.
+This interface has been around form the start and has proven to be quite flexible
+and robust. In spite of what you might think, the \type {somecommand} is not
+really defined in the \type {context} namespace, but in its own one called \type
+{core}, accessible via \type {context.core}.
+
+Next we describe the commands that are naturally defined in the \type {context}
+namespace. Some have counterparts at the macro level (like \type {bgroup}) but
+many haven't (for instance \type {rule}). We tried not to polute the \type
+{context} namespace too much but although we could have put the helpers in a
+separate namespace it would make usage a bit more unnatural.
+
+\startsection[title=Access to commands]

+\startsummary[title={context(".. some text ..")}]
+
+The string is flushed as|-|is:
+
+\starttyping

+\stopsummary

+\startsummary[title={context("format",...)}]
+
+The first string is a format specification according that is passed to the \LUA\
+function \type {format} in the \type {string} namespace. Following arguments are
+passed too.
+
+\stopsummary

+\startsummary[title={context(123,...)}]

+table with the four fields. The rule gets the current attributes.
+
+\stopsummary
+
+\startsummary[title={context.glyph(fontid,n) context.glyph(n)}]
+
+A glyph node is injected with the given font id. When no id is given, the current font
+is used. The glyph gets the current attributes.
+
+\stopsummary
+
+\startsummary[title={context.char(n) context.char(str)  context.char(tab)}]
+
+This will inject one or more copies of \type {\char} calls. You can pass a
+number, a string representing a number, or a table with numbers.
+
+\stopsummary
+
+\startsummary[title={context.utfchar(n) context.utfchar(str)}]
+
+This injects is \UTF\ character (one or more bytes). You can pass a number
+or a string representing a numbers. You need to be aware of special
+characters in \TEX, like \type {#}.
+
+\stopsummary
+
+\stopsection
+
+\startsection[title={Registers}]
+
+This is a table that hosts a couple of functions. The following \type {new}
+ones are available:
+
+\starttyping
+local n = newdimen (name)
+local n = newskip  (name)
+local n = newcount (name)
+local n = newmuskip(name)
+local n = newtoks  (name)
+local n = newbox   (name)
+\stoptyping
+
+These define a register with name \type {name} at the \LUA\ end and \type {\name}
+at the \TEX\ end. The registers' number is returned. The next function is like
+\type {\chardef}: it defines \type {\name} with value \type {n}.
+
+\starttyping
+local n = newchar(name,n)
+\stoptyping
+
+It's not likely that you will use any of these commands, if only because when
+you're operating from the \LUA\ end using \LUA\ variables is more convenient.
+
+\stopsection
+
+\startsection[title=Catcodes]
+
+Normally we operate under the so called \type {context} catcode regime. This
+means that content gets piped to \TEX\ using the same meanings for characters as
+you normally use in \CONTEXT. So, a \type {$} starts math. In \in {table}
+[tab:catcodes] we show the catcode regimes.
+
+\startplacetable[location=page,title={Catcode regimes},reference=tab:catcodes]
+    \showcharactercatcodes
+\stopplacetable
+
+\startsummary[title={context.catcodes}]
+
+The \type {context.catcodes} tables contains the internal numbers of the
+catcode tables used. The next table shows the names that can be used.
+
+\starttabulate[|lT|cT|lT|]
+\BC name     \BC mnemonic \BC \TEX\ command \NC \NR
+\NC context  \NC ctx      \NC ctxcatcodes   \NC \NR

+\NC verbatim \NC vrb      \NC vrbcatcodes   \NC \NR
+\stoptabulate
+
+\stopsummary
+
+\startsummary[title={context.newindexer(catcodeindex)}]
+
+This function defines a new indexer. You can think of the context command itself
+as an indexer. There are two (extra) predefined indexers:
+
+\starttyping
+context.verbatim = context.newindexer(context.catcodes.verbatim)
+context.puretext = context.newindexer(context.catcodes.text)
+\stoptyping
+
+\stopsummary
+
+\startsummary[title={context.pushcatcodes(n) context.popcatcodes()}]
+
+These commands switch to another catcode regime and back. They have to be used
+in pairs. Only the regimes atthe \LUA\ end are set.
+
+\stopsummary
+
+\startsummary[title={context.unprotect() context.protect()}]
+
+These commands switch to the protected regime and back. They have to be used in
+pairs. Beware: contrary to what its name suggests, the \type {unprotect} enables
+the protected regime. These functions also issue an \type {\unprotect} and \type
+{\protect} equivalent at the \TEX\ end.
+
+\stopsummary
+
+\startsummary[title={context.verbatim context.puretext}]
+
+The differences between these are subtle:

+    context.puretext.bold("Why do we use {\\bi $} at all?")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+Verbatim makes all characters letters while pure text leaves the backslash and
+curly braces special.
+
+\startpacked \getbuffer \stoppacked
+
+\stopsummary
+
+\startsummary[title={context.protected}]
+
+The protected namespace is only used for commands that are in the \CONTEXT\
+private namespace.
+
+\stopsummary
+
+\startsummary[title={context.escaped(str) context.escape(str)}]
+
+The first command pipes the escaped string to \TEX, while the second one just
+returns an unescaped string. The characters \typ {# $ % \ \ { }} are escaped.
+
+\stopsummary
+
+\startsummary[title={context.startcollecting() context.stopcollecting()}]
+
+These two commands will turn flushing to \TEX\ into collecting. This can be handy
+when you want to interface commands that grab arguments using delimiters and as
+such they are used deep down in some table related interfacing. You probably
+don't need them.
+
+\stopsummary
+
+\stopsection
+
+\startsection[title={Templates}]
+
+In addition to the regular template mechanism (part of the utilities) there is a
+dedicated template feature in the \type {context} namespace. An example demonstrates
+its working:
+
+\startbuffer
+\startluacode
+  local MyTable = [[
+    \bTABLE
+      \bTR
+         \bTD \bf %one_first% \eTD
+         \bTD %[one_second]% \eTD
+      \eTR
+      \bTR
+        \bTD \bf %two_first% \eTD
+        \bTD %[two_second]% \eTD
+      \eTR
+    \eTABLE
+  ]]
+
+  context.templates[MyTable] {
+    one_first  = "one",
+    two_first  = "two",
+    one_second = "just one $",
+    two_second = "just two $",
+  }
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This renders:
+
+\startlinecorrection
+    \getbuffer
+\stoplinecorrection
+
+You can also use more complex tables. Watch the space before and after the keys:
+
+\startbuffer
+\startluacode
+  local MyOtherTable = [[
+    \bTABLE
+      \bTR
+        \bTD \bf % ['one']['first'] % \eTD
+        \bTD %[ ['one']['second'] ]% \eTD
+      \eTR
+      \bTR
+        \bTD \bf % ['two']['first'] % \eTD
+        \bTD %[ ['two']['second'] ]% \eTD
+      \eTR
+    \eTABLE
+  ]]
+
+  local data = {
+    one = { first = "one", second = "only 1$" },
+    two = { first = "two", second = "only 2$" },
+  }
+
+  context.templates[MyOtherTable](data)
+
+  context.templates(MyOtherTable,data)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+We get:
+
+\startlinecorrection
+    \getbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title={Management}]
+
+\startsummary[title={context.functions}]
+
+This is private table that hosts managament of functions. You'd better leave this
+one alone!
+
+\stopsummary
+
+\startsummary[title={context.nodes}]
+
+Normally you will just use \type {context(<somenode>)} to flush a node and this
+private table is more for internal use.
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=String handlers]
+
+These two functions implement handlers that split a given string into lines and
+do something with it. We stick to showing their call. They are used for special
+purpose flushing, like flushing content to \TEX\ in commands discussed here. The
+\XML\ subsystem also used a couple of dedicated handlers.
+
+\starttyping
+local foo = newtexthandler {
+    content    = function(s) ... end,
+    endofline  = function(s) ... end,
+    emptyline  = function(s) ... end,
+    simpleline = function(s) ... end,
+}
+
+local foo = newverbosehandler {
+    line    = function(s) ... end,
+    space   = function(s) ... end,
+    content = function(s) ... end,
+    before  = function() ... end,
+    after   = function() ... end,
+}
+\stoptyping
+
+\startsummary[title={context.printlines(str)}]
+
+The low level \type {tex.print} function pipes its content to \TEX\ and thereby
+terminates at at \type {\r} (cariage return, \ASCII\ 13), although it depends on
+the way catcodes and line endings are set up. In fact, a line ending in \TEX\ is
+not really one, as it gets replaced by a space. Only several lines in succession
+indicate a new paragraph.
+
+\startbuffer
+\startluacode
+    tex.print("line 1\n line 2\r line 3")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This renders only two lines:
+
+\getbuffer
+
+\startbuffer
+\startluacode
+    context("line 1\n line 2\r line 3")
+\stopluacode
+\stopbuffer
+
+However, the \type {context} command gives all three lines:
+
+\typebuffer
+
+Like:
+
+\getbuffer
+
+The \type {context.printlines} command is a direct way to print a string in a way
+similar to reading from a file. So,
+
+\starttyping
+tex.print(io.loaddata(resolvers.findfile("tufte")))
+\stoptyping
+
+Gives one line, while:
+
+\starttyping
+context.printlines(io.loaddata(resolvers.findfile("tufte")))
+\stoptyping
+
+gives them all, as does:
+
+\starttyping
+context(io.loaddata(resolvers.findfile("tufte")))
+\stoptyping
+
+as does a na\"ive:
+
+\starttyping
+tex.print((string.gsub(io.loaddata(resolvers.findfile("tufte")),"\r","\n")))
+\stoptyping
+
+But, because successive lines need to become paragraph separators as bit more
+work is needed and that is what \type {printlines} and \type {context} do for
+you. However, a more convenient alternative is presented next.
+
+\stopsummary
+
+\startsummary[title={context.loadfile(name)}]
+
+This function locates and loads the file with the given name. The leading and
+trailing spaces are stripped.
+
+\stopsummary
+
+\startsummary[title={context.runfile(name)}]
+
+This function locates and processes the file with the given name. The assumption
+is that it is a valid \LUA\ file! When no suffix is given, the suffix \type {cld}
+(\CONTEXT\ \LUA\ document) is used.
+
+\stopsummary
+
+\startsummary[title={context.viafile(data[,tag])}]
+
+The \type {data} is saved to a (pseudo) file with the optional name \type {tag}
+and read in again from that file. This is a robust way to make sure that the data
+gets processed like any other data read from file. It permits all kind of
+juggling with catcodes, verbatim and alike.
+
+\stopsummary
+
+\stopsection
+
+\startsection[title={Helpers}]
+
+\startsummary[title={context.tocontext(variable)}]
+
+For documentation or tracing it can be handy to serialize a variable. The \type
+{tocontext} function does this:
+
+\starttyping
+context.tocontext(true)
+context.tocontext(123)
+context.tocontext("foo")
+context.tocontext(tonumber)
+context.tocontext(nil)
+context.tocontext({ "foo", "bar" },true)
+context.tocontext({ this = { foo , "bar" } },true)
+\stoptyping
+
+Beware, \type {tocontext} is also a table that you can assign to, but that might
+spoil serialization. This property makes it possible to extend the serializer.
+
+\stopsummary
+
+\startsummary[title={context.tobuffer(name,str[,catcodes])}]
+
+With this function you can put content in a buffer, optionally under a catcode
+regime.
+
+\stopsummary
+
+\startsummary[title={context.tolines(str[,true])}]
+
+This function splits the string in lines and flushes them one by one. When the
+second argument is \type {true} leading and trailing spaces are stripped. Each
+flushed line always gets one space appended.
+
+\stopsummary
+
+\startsummary[title={context.fprint([regime,]fmt,...),tex.fprint([regime,]fmt,...)}]
+
+The \type {tex.fprint} is just there to complement the other flushers in the
+\type {tex} namespace and therefore we also have it in the \type {context}
+namespace.
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=Tracing]
+
+\startsummary[title={context.settracing(true or false))}]
+
+You can trace the \TEX\ code that is generated at the \TEX\ end with:
+
+\starttyping
+\enabletrackers[context.trace]
+\stoptyping
+
+The \LUA\ function sets the tracing from the \LUA\ end. As the \type {context}
+command is used a lot in the core, you can expect some more tracing that the code
+that you're currently checking.
+
+\stopsummary
+
+\startsummary[title={context.pushlogger(fnc) context.poplogger() context.getlogger()}]
+
+You can provide your own logger if needed. The pushed function receives one string
+argument. The getter returns three functions:
+
+\starttyping
+local flush, writer, flushdirect = context.getlogger()
+\stoptyping
+
+The \type{flush} function is similar to \type {tex.sprint} and appends its
+arguments, while \type {flushdirect} treats each argument as a line and behaves
+like \type {tex.print}. The \type {flush} function adds braces and paranthesis
+around its arguments, apartt from the first one, which is considered to be a
+command. Examples are:
+
+\starttyping
+flush("one",2,"three") -- catcode, strings|numbers
+writer("\\color",{"red"},"this is red")
+\stoptyping
+
+and:
+
+\starttyping
+flush(context.catcodes.verbatim,"one",2,"three")
+writer(context.catcodes.verbatim,"\\color",{"red"},"this is red")
+\stoptyping
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=States]
+
+There are several ways to implement alternative code paths in \CONTEXT\ but modes
+and conditionals are used mostly. There area few helpers for that.
+
+\startsummary[title={context.conditionals context.setconditional(name,value)}]
+
+Conditionals are used to keep a state. You can set their value using the setter,
+but their effect is not immediate but part of the current sequence of commands
+which is delegated to \TEX. However, you can easily keep track of your state
+at the \LUA\ end with an extra boolean. So, after
+
+\starttyping
+if context.conditionals.whatever then
+    context.setconditional("dothis",false)
+else
+    context.setconditional("dothat",true)
+end
+\stoptyping
+
+the value of \type {dothis} and \type {dothat} conditions are not yet set in
+\LUA.
+
+\stopsummary
+
+\startsummary[title={context.modes context.setmode(name,value)}]
+
+As with conditionals, you can (re)set the modes in \LUA\ but their values
+get changes as part of the command sequence which is delayed till after the
+\LUA\ call.
+
+\stopsummary
+
+\startsummary[title={context.systemmodes context.setsystemmode(name,value)}]
+
+The same applies as for regular modes.
+
+\stopsummary
+
+\startsummary[title={context.trialtypesetting()}]
+
+This function returns \type {true} if we're in trial typesetting mode (used when
+for instance prerolling a table).
+
+\stopsummary
+
+\stopsection
+
+\startsection[title=Steps]
+
+The stepper permits stepwise processing of \CONTEXT\ code: after a step contyrol
+gets delegated to \CONTEXT\ and afterwards back to \LUA. There main limitation of
+this mechanism is that it cannot exceed the number of input levels.
+
+\startsummary[title={context.stepwise() context.step([str])}]
+
+Usage is as follows:
+
+\starttyping
+context.stepwise (function()
+    ...
+    context.step(...)
+    ...
+    context.step(...)
+    ...
+    context.stepwise (function()
+        ...
+        context.step(...)
+        ...
+    context.step(...)
+    ...
+    end)
+    ...
+    context.step(...)
+    ...
+    context.step(...)
+    ...
+end)

+\startsection[title=Introduction]
+
+\index{verbatim}
+
+If you are familiar with traditional \TEX, you know that some characters have
+special meanings. For instance a \type {$} starts and ends inline math mode:
+
+\starttyping
+$e=mc^2$
+\stoptyping
+
+If we want to typeset math from the \LUA\ end, we can say:
+
+\starttyping
+context.mathematics("e=mc^2")
+\stoptyping
+
+This is in fact:
+
+\starttyping
+\mathematics{e=mc^2}
+\stoptyping
+
+However, if we want to typeset a dollar and use the \type {ctxcatcodes} regime,
+we need to explicitly access that character using \type {\char} or use a command
+that expands into the character with catcode other.
+
+One step further is that we typeset all characters as they are and this is called
+verbatim. In that mode all characters are tokens without any special meaning.
+
+\stopsection
+
+\startsection[title=Special treatment]
+
+The formula in the introduction can be typeset verbatim as follows:
+
+\startbuffer
+context.verbatim("$e=mc^2$")
+\stopbuffer
+
+\typebuffer
+
+This gives:
+
+\ctxluabuffer
+
+You can also do things like this:
+
+\startbuffer
+context.verbatim.bold("$e=mc^2$")
+\stopbuffer
+
+\typebuffer
+
+Which gives:
+
+\ctxluabuffer
+
+So, within the \type {verbatim} namespace, each command gets its arguments
+verbatim.
+
+\startbuffer
+context.verbatim.inframed({ offset = "0pt" }, "$e=mc^2$")
+\stopbuffer
+
+\typebuffer
+
+Here we get: \ctxluabuffer. So, settings and alike are processed as if the user
+had used a regular \type {context.inframed} but the content comes out verbose.
+
+If you wonder why verbatim is needed as we also have the \type {type} function
+(macro) the answer is that it is faster, easier to key in, and sometimes the only
+way to get the desired result.
+
+\stopsection
+
+\startsection[title=Multiple lines]
+
+Currently we have to deal with linebreaks in a special way. This is due to the
+way \TEX\ deals with linebreaks. In fact, when we print something to \TEX, the
+text after a \type {\n} is simply ignored.
+
+For this reason we have a few helpers. If you want to put something in a buffer,
+you cannot use the regular buffer functions unless you make sure that they are
+not overwritten while you're still at the \LUA\ end.
+
+\starttyping
+context.tobuffer("temp",str)
+context.getbuffer("temp")
+\stoptyping
+
+Another helper is the following. It splits the string into lines and feeds them
+piecewise using the \type {context} function and in the process adds a space at
+the end of the line (as this is what \TEX\ normally does.
+
+\starttyping
+context.tolines(str)
+\stoptyping
+
+Catcodes can get in the way when you pipe something to \TEX\ that itself changes
+the catcodes. This happens for instance when you write buffers that themselves
+have buffers or have code that changes the line endings as with \type
+{startlines}. In that case you need to feed back the content as if it were a
+file. This is done with:
+
+\starttyping
+context.viafile(str)
+\stoptyping
+
+The string can contain newlines. The string is written to a virtual file that is
+input. Currently names looks like \type {virtual://virtualfile.1} but future
+versions might have a different name part, so best use the variable instead.
+After all, you don't know the current number in advance anyway.
+
+\stopsection
+
+\startsection[title=Pretty printing]
+
+In \CONTEXT\ \MKII\ there have always been pretty printing options. We needed it
+for manuals and it was also handy to print sources in the same colors as the
+editor uses. Most of those pretty printers work in a line|-|by|-|line basis, but
+some are more complex, especially when comments or strings can span multiple
+lines.
+
+When the first versions of \LUATEX\ showed up, rewriting the \MKII\ code to use
+\LUA\ was a nice exercise and the code was not that bad, but when \LPEG\ showed
+up, I put it on the agenda to reimplement them again.
+
+We only ship a few pretty printers. Users normally have their own preferences and
+it's not easy to make general purpose pretty printers. This is why the new
+framework is a bit more flexible and permits users to kick in their own code.
+
+Pretty printing involves more than coloring some characters or words:
+
+\startitemize[packed]
+\startitem spaces should honoured and can be visualized \stopitem
+\startitem newlines and empty lins need to be honoured as well \stopitem
+\startitem optionally lines have to be numbered but \stopitem
+\startitem wrapped around lines should not be numbered \stopitem
+\stopitemize
+
+It's not much fun to deal with these matters each time that you write a pretty
+printer. This is why we can start with an existing one like the default pretty
+printer. We show several variants of doing the same. We start with a simple clone
+of the default parser. \footnote {In the meantime the lexer of the \SCITE\ editor
+that I used also provides a mechanism for using \LPEG\ based lexers. Although in
+the pretty printing code we need a more liberal one I might backport the lexers I
+wrote for editing \TEX, \METAPOST, \LUA, \CLD, \XML\ and \PDF\ as a variant for
+the ones we use in \MKIV\ now. That way we get similar colorschemes which might
+be handy sometimes.}

+
+local parser = P(grammar)
+
+visualizers.register("test-0", { parser = parser })
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+We distinguish between grammars (tables with rules), parsers (a grammar turned
+into an \LPEG\ expression), and handlers (collections of functions that can be
+applied. All three are registered under a name and the verbatim commands can
+refer to that name.
+
+\startbuffer
+\starttyping[option=test-0,color=]
+Test 123,

+\stoptyping
+\stopbuffer
+
+\typebuffer
+
+Nothing special happens here. We just get straightforward verbatim.
+
+\getbuffer
+
+Next we are going to color digits. We collect as many as possible in a row, so
+that we minimize the calls to the colorizer.
+
+\startbuffer
+local patterns, P, V = lpeg.patterns, lpeg.P, lpeg.V

+} )
+
+local parser = P(grammar)
+
+visualizers.register("test-1", { parser = parser })
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+Watch how we define a new rule for the digits and overload the pattern rule. We
+can refer to the default rule by using a prefix. This is needed when we define a

+
+\startbuffer
+\starttyping[option=test-1,color=]
+Test 123,
+test 456 and
+test 789!
+\stoptyping
+\stopbuffer
+
+\typebuffer
+
+This time the digits get colored.
+
+\getbuffer
+
+In a similar way we can colorize letters. As with the previous example, we use
+\CONTEXT\ commands at the \LUA\ end.
+
+\startluacode
+local patterns, P, V = lpeg.patterns, lpeg.P, lpeg.V
+
+local function colorize_lowercase(s)
+  context.color{"darkgreen"}
+  visualizers.writeargument(s)
+end
+local function colorize_uppercase(s)
+  context.color{"darkblue"}
+  visualizers.writeargument(s)
+end
+
+local grammar = visualizers.newgrammar("default", {
+
+  lowercase = patterns.lowercase^1 / colorize_lowercase,
+  uppercase = patterns.uppercase^1 / colorize_uppercase,
+
+  pattern =
+      V("lowercase")
+    + V("uppercase")
+    + V("default:pattern"),
+
+  visualizer = V("pattern")^1

+} )
+
+local parser = P(grammar)
+
+visualizers.register("test-2", { parser = parser })
+\stopluacode

+\startbuffer
+\starttyping[option=test-2,color=]
+Test 123,
+test 456 and
+test 789!
+\stoptyping
+\stopbuffer
+
+\typebuffer
+
+Again we get some coloring.
+
+\getbuffer
+
+It will be clear that the amount of rules and functions is larger when we use a
+more complex parser. It is for this reason that we can group functions in
+handlers. We can also make a pretty printer configurable by defining handlers at
+the \TEX\ end.
+
+\startbuffer

+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \LUA\ code now looks different. Watch out: we need an indirect call to for
+instance \type {MyDigit} because a second argument can be passed: the settings

+The function \type {visualizer.write} takes care of spaces and newlines.
+
+\getbuffer
+
+We have a few more helpers:
+
+\starttabulate[|||]
+\NC \type{visualizers.write}          \NC interprets the argument and applies methods \NC \NR
+\NC \type{visualizers.writenewline}   \NC goes to the next line (similar to \type {\par} \NC \NR
+\NC \type{visualizers.writeemptyline} \NC inserts an empty line (similer to \type {\blank} \NC \NR
+\NC \type{visualizers.writespace}     \NC inserts a (visible) space \NC \NR
+\NC \type{visualizers.writedefault}   \NC writes the argument verbatim without interpretation \NC \NR
+\stoptabulate
+
+These mechanism have quite some overhead in terms of function calls. In the worst
+case each token needs a (nested) call. However, doing all this at the \TEX\ end
+also comes at a price. So, in practice this approach is more flexible but without
+too large a penalty.
+
+In all these examples we typeset the text verbose: what is keyed in normally
+comes out (either or not with colors), so spaces stay spaces and linebreaks are
+kept.
+
+\startbuffer
+local function parser(s)
+  local s = string.gsub(s,"show","demonstrate")
+  local s = string.gsub(s,"'re"," are")
+  context(s)
+end
+
+visualizers.register("test-5", { parser = parser })
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+\startbuffer
+\starttyping[option=test-5,color=darkred,style=]
+This is just some text to show what we can do with this mechanism. In
+spite of what you might think we're not bound to verbose text.
+\stoptyping
+\stopbuffer
+
+We can apply this visualizer as follows:
+
+\typebuffer
+
+This time the text gets properly aligned:
+
+\getbuffer
+
+It often makes sense to use a buffer:
+
+\startbuffer
+\startbuffer[demo]
+This is just some text to show what we can do with this mechanism. In
+spite of what you might think we're not bound to verbose text.
+\stopbuffer
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Instead of processing the buffer in verbatim mode you can then
+process it directly:
+
+\startbuffer
+\setuptyping[file][option=test-5,color=darkred,style=]
+\ctxluabuffer[demo]
+\stopbuffer
+
+\typebuffer
+
+Which gives:
+
+\start \getbuffer \stop
+
+In this case, the space is a normal space and not the fixed verbatim space, which
+looks better.

+
+\start
+
+It's hard to predict what kind of caption placements users want. The amount of
+variation if large and thereby any system of specifying them will look complex.
+So, examples are the best way to show them.
+
+\startbuffer

+  [location=bottom]

+\stopbuffer
+
+\typebuffer \getbuffer
+
+In this document we typeset on a grid. For more complex cases and when a document
+is processed without any user intervention, this is often a bad idea because the
+snapper can decide to make sure that there is enough space above and below an
+element. You can however influence the snapper explicitly:
+
+\startbuffer
+\setupcaption
+  [figure]
+  [location=top]
+\placefigure
+  [left,line]
+  {}{\externalfigure[dummy][lines=2,width=4cm]}
+\fakewords{60}{80} \par
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Normally a side float plus caption has a normalized (strut) depth while also
+top skip gets applied. When one of the grid related options \type {height}, \type
+{line}, \type {depth}, \type {grid} or \type {halfline} is given the top skip
+correction is removed. The \type {grid} option removes the depth too. The \type
+{grid} option removes the depth while the \type {height} and \type {depth}
+options adds an extra amount of strut depth. The \type {depth} option also adds a
+line and \type {halfline} removes a line but adds strut height. Indeed this sounds
+complicated so best play with it a bit.
+
+Keep in mind that the snapper plays safe and therefore tends to add more space when
+needed. You can set a grid parameter that controls it:
+
+\starttyping
+\setupfloats[grid=tolerant]
+\stoptyping
+
+Currently this only applies to side floats but in the future we might support it
+for regular floats too.

+\startchapter[title={About this document}]
+
+This document is typeset in \CONTEXT\ using \LUATEX\ with \METAPOST. We use only
+one font: the Computer Modern Typewriter. The verbatim portions of the text are
+typeset in its mono spaced variant. One of the reasons that I chose this font is
+that we need a mono spaced font to typeset the example code, and the Computer
+Modern Typewriter is one the best there is. This font combines well with many
+other typefaces, but the sometimes excessive use of different fonts (and sizes)
+in the styles that I have to implement made me long for simplicity. And so I
+decided to stick to one font. A careful reader will notice that this document has
+character protruding enabled (resulting in hanging punctuation).
+
+We use a couple of colors. Again, I went for simplicity and use rather primary
+colors, although I do use them in transparent variants as well.
+
+There is not much more to say, apart from that I want to thank our customers as
+well as \CONTEXT\ users for asking me to implement \DTP\ competing styles and
+features. Their demands drive \CONTEXT\ in directions we could not have foreseen
+when we started its development.
+
+We use a (transparent) gray background behind the text so that we have an
+indication where the text area is positioned relative to the page. It also
+enables us to comfortably turn on the grid.
+
+Some features shown here are relatively new and therefore they occasionally are
+improved. As a result some aspects of their functionality may change.

+This control is needed if you want to typeset documents in a semi desk top
+publishing way.
+
+When you combine technical graphics, you may wish to align the content optically.
+This can be done with the \type {offset} command. We will demonstrate this with a

+These examples demonstrate that the dimensions change with the offset. You can

+
+In the previous chapter we demonstrated how a side float can be moved up or down
+by providing a placement directive or by preceding the placement with \type
+{\movesidefloat}. Such a move can be used to align a graphic with particular line
+of text. This command can also be used for alignment purposes similar to the
+\type {\offset} command. We will demonstrate this with the following graphics.
+
+\startbuffer
+\startreusableMPgraphic{gnu}
+  fill fullsquare xyscaled( 4cm, 1cm) withcolor \MPcolor{red} ;
+  fill unitsquare xyscaled(-1cm,.5cm)
+                   shifted (0,-.25cm) withcolor \MPcolor{gray} ;
+\stopreusableMPgraphic

+                   shifted (0,-.25cm) withcolor \MPcolor{gray} ;
+\stopreusableMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+In the next two examples we shift the \type {gnu} and \type {gnat} graphics
+horizontally in order to get them aligned. The move does not change the
+dimensions of the float, but they do influence the paragraph shape.
+
+\startbuffer[a]

+\blank
+
+It is possible to shift vertically by setting \type {y}, but this is often a bad
+idea and definitely may spoil alignment of graphics to the grid. If you have to
+revert to this trick, you are probably working in document screw||up mode. This
+is why in grid mode, we automatically round to an equal number of lines.
+
+If you know what text you're dealing with and also can be sure about the height
+of a graphic, you can trick \CONTEXT\ to ignore the dimensions of a graphic. Here
+we use the graphic:
+
+\startbuffer
+\startreusableMPgraphic{gnome}
+  fill fullsquare xyscaled(2cm, 1cm) withcolor \MPcolor{red} ;
+  fill fullsquare xyscaled(1cm,.5cm) withcolor \MPcolor{gray} ;
+\stopreusableMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\placefigure[leftmargin,none,reset]{}{\reuseMPgraphic{gnome}}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The graphic is moved into the margin (\type {leftmargin}), has no caption (\type
+{none}), and all kind of tricky housekeeping is reset (\type {reset}).
+
+\startbuffer
+\placefigure[left,none,high,low]{}{\reuseMPgraphic{gnome}}
+\stopbuffer
+
+\getbuffer
+
+Now the next graphic is not influenced by the previous one, so we can place them
+close to each other. Use these tricks with care, especially if your document
+source is reused and the typeset products are not carefully checked.
+
+\typebuffer
+
+When \CONTEXT\ tries to determine if a float fits, it makes a couple of
+assumptions, for instance that the available room equals the text height minus
+the height of the text so far. You can slightly influence the way these values
+are interpreted by setting the calculation method. You can set the methods as
+follows:
+
+\starttyping
+\setupfloats[textmethod=0,sidemethod=1]
+\stoptyping
+
+Method~0 just looks at the raw dimensions, while method~1 lessens the maximum
+text height by one percent, thereby playing safe. Method~2 takes a window of
+1~point. This may lead to better decisions since we may run into rounding errors
+of several scaled points (which is small but troublesome). Method~2 is well
+suited when typesetting on a grid, because there everything has to fit in a
+rounded number of lines, which leaves no room for rounding errors.

+\stopusableMPgraphic
+
+As you may know by now, we can use the directives \type {high}, \type {low},
+\type {height}, \type {depth} and \type {line} to influence the spacing around a
+side float. A real tight spacing can be achieved with \type {fit}.
+
+\starttyping
+\placefigure[left,fit,none]{}{some graphic}
+\stoptyping
+
+\placefigure[left,fit,none]{}{\useMPgraphic{demo-1}{color=red}}
+
+This kind of placements only make sense in special situations, because normally
+you don't want the graphic to touch the text.
+
+If you think that this is all a user may want, you're wrong. It is not imaginary
+that graphics have small pieces sticking out and|/|or lots of white space as part
+of their design. In that case, the bounding box can be set to a smaller size.
+
+\placefigure
+  [left,fit,none]
+  {}
+  {\setlayer
+      [graphics]
+      {\useMPgraphic{demo-2}{color=red,morecolor=tgreen}}}
+
+Now, when handling a side float, \CONTEXT\ first places the float, and then
+starts with typesetting the paragraph, cleverly avoiding the graphic. However,
+when the graphic is virtually larger than its known size, it may cover part of
+the preceding paragraph.
+
+How come that the graphic starting this paragraph does not do that? It is because
+we explicitly moved it to the background. This involves some preparation. At the
+document level, we define a layer called \type {graphic}.
+
+\starttyping
+\definelayer[graphics][position=yes]
+\stoptyping
+
+The position directive tells \CONTEXT\ that it should honour the position of the
+graphic. Next we must make sure that this layer is placed.
+
+\starttyping
+\setupbackgounds[page][background=graphics]
+\stoptyping
+
+Now we're ready to move graphics to this layer:
+
+\starttyping
+\placefigure
+  [left,fit,none]
+  {}{\setlayer[graphics]{graphic}}
+\stoptyping
+
+It's now a small step to more advanced movements. Say that you want to move the
+graphic a little bit to the left. In that case you can tell the layer placement
+to do so.
+
+\starttyping
+\placefigure
+  [left,fit,none]{}{\setlayer[graphics][hoffset=-12pt]{graphic}}
+\stoptyping
+
+From this you can deduce that there is also a movement in the vertical direction
+using \type {voffset}. In addition you can anchor the graphic using the \type
+{location} parameter and provide offsets.
+
+\placefigure
+  [left,fit,none]
+  {}
+  {\setlayer
+     [graphics][hoffset=-12pt]
+     {\useMPgraphic{demo-2}{color=red,morecolor=tgreen}}}
+
+As soon as you run into situations where float placement is to be consistently
+enforced, you will feel the need for dedicate placement macros. For example:
+
+\startbuffer
+\definefloat
+  [somefloat]
+  [figure]
+
+\setupfloat
+  [somefloat]
+  [sidespaceafter=,
+   sidespacebefore=,
+   default={left,none}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Instead of resetting the side spacing, we could have default to \type {high,low},
+but this way we can overload the default placement and still get zero spacing.
+
+Throughout this manual we discuss features related to overlays and layers. These
+permit you to move content around in ways that either or not depend on the text
+flow. We have now come to another trick based on these mechanisms: bleeding.
+
+When printing a document, you need to take into account that when graphics go
+beyond the page boundary, you need to compensate for inaccuracies in cutting the
+pages. Such graphics are called bleeding graphics and the amount of bleed is
+often a few millimeters.
+
+The best way to handle such graphics is to use the correct dimensions and play
+with the edge widths and distances in combination with backspace and cut space. In
+a properly set up layout and by using a well designed set of predefined graphic
+placements, you can handle this quite well. A bleeding figure can be defined as
+follows:
+
+\startbuffer
+\definefloat
+  [edgefigure]
+  [figure]
+
+\setupfloat
+  [edgefigure]
+  [default={inner,height,high,low,none},
+   maxwidth=4cm]
+
+\defineexternalfigure
+  [edgefigure]
+  [width=\dimexpr\backspace+4cm-1mm\relax,
+   lines=4]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The default placement is pre|-|configured to have no additional vertical space and
+align on the height of a line (this is default behaviour so the \type {height}
+key is redundant here. The 1mm in the previous definition simulates what happens
+when a page is cut off slightly wrong: we get an annoying gap.
+
+\startbuffer[a]
+\placeedgefigure
+  {}
+  {\externalfigure[hacker][edgefigure]}
+\stopbuffer
+
+\typebuffer[a] \getbuffer[a] \fakewords{50}{100}
+
+One of the nice things about \TEX\ is that you can fine tune dimensions pretty
+well. So, instead of the previous placement, which turns out rather ugly, we can
+come up with a better one:
+
+\startbuffer
+\setupfloat
+  [edgefigure]
+  [default={inner,height,high,low,none},
+   maxwidth=4cm,
+   margin=\strutdepth]
+
+\defineexternalfigure
+  [edgefigure]
+  [width=\dimexpr\backspace+4cm+2mm\relax,
+   height=\dimexpr3\lineheight+\strutheight\relax]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This time we take no risk and add 2mm to the dimensions so that we can be sure
+that the edge of the graphic falls outside the page boundary.
+
+\getbuffer[a] \fakewords{50}{100}
+
+The \CONTEXT\ resourse library modules provide means to report back the
+dimensions of graphics used in a document, so that you can develop (tune) them
+with the proper dimensions. In practice a slightly wider than normal graphic
+(scaling it horizontally a few millimeters more) does not harm the visual
+appearance that much, so adapting a graphic to this kind of bleeding is not
+really needed.
+
+In addition to this (rather natural) way of adding bleed to a graphic, you can
+apply the \type {\bleed} macro. In the previously discussed method the figure
+placement mechanisms work with the real dimensions. The \type {bleed} macro is
+using scaling in a different way: from the perspective of \CONTEXT\ the graphic
+remains its original dimensions and the figure placement mechanisms will act
+accordingly. We will give a couple of examples of using this macro.
+
+Permitted bleeding locations are \type {l}, \type {r}, \type {t}, \type {b},
+\type {lr}, \type {bl}, \type {br}, \type {tl} and \type {tr}.
+
+\startbuffer
+\placesomefloat
+  [left,none,fit]
+  {}
+  {\setupbleeding[offset=5mm]%
+   \bleed[width=5cm,height=1cm,location=l]
+     {\externalfigure[mill][bleed]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{50}{100}
+
+\startbuffer
+\placesomefloat
+  [left,none,fit]
+  {}
+  {\setupbleeding[offset=2mm]%
+   \bleed[width=5cm,height=1cm,location=l]
+     {\externalfigure[mill][bleed]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{50}{100}
+
+The amount of bleeding depends on the postprocessing. In the previous paragraph
+we used a bleed offset of 5mm, and here we used 2mm. Because the graphic is
+scaled in order to match the bleed, it will be slightly distorted. With small
+values this will go unnoticed. You can set the offset with:
+
+\starttyping
+\setupbleeding[offset=5mm]
+\stoptyping
+
+Bleeding itself is accomplished by the \type {\bleed} macro as in:
+
+\starttyping
+\bleed
+  [width=5cm,height=1cm,location=l]
+  {\externalfigure[mill][width=\bleedwidth,height=\bleedheight]}
+\stoptyping
+
+It is kind of awkward to pass those two dimensions so here is a shorter way of
+doing the same:
+
+\starttyping
+\bleed
+  [width=5cm,height=1cm,location=l]
+  {\externalfigure[mill][bleed]}
+\stoptyping
+
+In fact, this uses the following definition:
+
+\starttyping
+\defineexternalfigure[bleed][width=\bleedwidth,height=\bleedheight]
+\stoptyping
+
+You can influence the scaling of a graphic by setting the \type {stretch}
+parameters. The location parameter determines the direction of the stretch: \type
+{l}~(left), \type {r}~(right), \type {t}~(top), \type {b}~(bottom) or a
+combination of these. We will now combine the previous example code with this
+knowledge.
+
+\startbuffer
+\placefigure
+  [left]
+  {}
+  {\bleed
+     [stretch=no,voffset=0pt,hoffset=1cm]
+     {\externalfigure[detcow][bleed]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords {100} {150}
+
+\startbuffer
+\placefigure
+  [left]
+  {}
+  {\bleed
+     [width=5cm,height=3cm,location=l]
+     {\externalfigure[detcow][bleed]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords {100} {150}
+
+\startbuffer
+\placefigure
+  [right]

+     {\externalfigure[detcow][bleed]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords {100} {150}
+
+You can combine this feature with layers. We will now show a few applications
+which may look like magic at first glance, but will become natural to your
+repertoire once you have played with them.
+
+The next example moves the graphic to a layer associated with the (current) page.
+
+\startbuffer
+\placefigure
+  [right,none]
+  {}
+  {\setlayer
+     [graphics]
+     {\bleed
+        [width=5cm,height=3cm,location=rb]
+        {\externalfigure[detcow][bleed]}}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords {100} {150}
+
+You can also predefine locations where graphics (or other content) needs to be
+anchored. A direct call to anchor looks as follows:
+
+\starttyping
+\placefigure
+  [left,none]
+  {}
+  {\anchor
+     [text-1]
+     [location=lt,hoffset=max,voffset=max]
+     [width=3cm,height=3cm,frame=on]%
+     {\externalfigure[detcow][width=5cm,frame=on]}}
+\stoptyping
+
+This will anchor a graphic in one of the text layers, but at the cost of
+specifying this in the document source. One way around this is to predefine
+anchors.
+
+\startbuffer
+\defineanchor[rightbottom][text-1][location=lt,hoffset=max,voffset=max]
+\defineanchor[righttop]   [text-1][location=lb,hoffset=max]
+\defineanchor[leftbottom] [text-1][location=rt,voffset=max]
+\defineanchor[lefttop]    [text-1][location=rb]
+\stopbuffer
+
+\startbuffer
+\defineanchor[rightbottom][text-1][preset=rightbottom]
+\defineanchor[righttop]   [text-1][preset=righttop]
+\defineanchor[leftbottom] [text-1][preset=leftbottom]
+\defineanchor[lefttop]    [text-1][preset=lefttop]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We will apply this to a predefined float type.
+
+\startbuffer
+\definefloat[myfigure][figure]
+\setupfloat[myfigure][sidespaceafter=,sidespacebefore=]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Our previous example can now be reduced to:
+
+\startbuffer
+\placemyfigure

+  {\anchor[rightbottom]
+     {\externalfigure[detcow][width=5cm,frame=on]}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords {100} {150}
+
+You can still specify dimensions and anchors can be combined with bleeding. Of
+course this kind of mixed usage means that you need to have some feeling for what
+these mechanisms do.

+
+\index {floats}
+
+Graphics, tables and alike are often treated as floating bodies. This means that
+when such a body does not fit on the current page, it will be moved to the next
+one. In the examples we will use figures, but much of what we demonstrate here
+applies to all floats.
+
+A side float is a float which placement one way or another depends on the text
+that follows it. In its simplest form, the text flows around it, for instance in:
+
+\startbuffer
+\placefigure[left,none]{caption}{\framed[height=1cm]{graphic}}
+\stopbuffer
+
+\typebuffer
+
+The first keyword of such a call is treated as a placement directive, so this
+figure will be placed left. The \type {none} directive nils the caption.
+
+\getbuffer \fakewords{60}{80}
+
+When the figure does not fit on the page, a page break is issued. A figure can
+span multiple paragraphs. When a next graphic is placed the previous figure will
+be padded if needed. First an example of multiple paragraphs.
+
+\getbuffer \fakewords{30}{40} \par \fakewords{30}{40}
+
+Multiple floats in a row will lead to padding. The amount of padding is a
+combination of empty lines and the normal white space following the float. The
+visual quality of the result depends on the graphic itself.

+
+\stop
+
+Here we show the baseline of the first paragraph after the float as well as the
+filler. The whitespace around a graphic also depends on the inter|-|paragraph
+whitespace. As with many automated mechanisms, compromises are made. A one point
+smaller figure may result in an extra empty line.
+
+Later we will demonstrate a lot of tuning options, but first we give a few more
+examples. Most of the tuning options can be driven by keywords as well as
+(global) settings.

+The \type {nonumber} keyword suppresses the label and figure number. You can do
+this for all figures with
+
+\starttyping
+\setupcaption[figure][number=no]
+\stoptyping
+
+The previous placement command results in the following side float.
+
+\getbuffer \fakewords{80}{100}
+
+Another handy keyword is \type {none}.

+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{80}{100}
+
+Control over spacing is exercised by means of the keywords \type {high}, \type
+{low} and \type {fit}.
+
+\startbuffer

+
+In the examples so far, we saw additional spacing around the graphic. We will now
+(for a while) disable the surrounding whitespace.
+
+\startbuffer
+\setupfloat

+  [sidespacebefore=none,
+   sidespaceafter=none]
+\stopbuffer

+
+With these settings a simple left placement looks as follows. The top of the side
+float aligns with the maximum height of a line.
+
+\start \getbuffer \tracesidefloatstrue
+
+\startbuffer
+\placefigure
+  [left,none]
+  {} {\framed[height=1cm]{graphic}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40} \par \stop
+
+You can change the alignment by setting the \type {sidealign} variable, for
+instance:
+
+\starttyping
+\setupfloat
+  [figure]
+  [sidealign=line]
+\stoptyping
+
+The three keywords \type {height}, \type {line} and \type {depth} can also be
+passed directly:
+
+\startbuffer
+\placefigure
+  [left,none,height]{}
+  {\framed[height=1cm]{graphic}}
+\stopbuffer
+
+\typebuffer
+
+The three alignments disable the spacing before the float and show up as follows.
+
+\bgroup \tracesidefloatstrue \getbuffer \fakewords{30}{40} \par \egroup
+
+\startbuffer
+\placefigure
+  [left,none,line]{}

+\bgroup \tracesidefloatstrue \getbuffer \fakewords{30}{40} \par \egroup
+
+So far the floats took up space in the main text body area. In addition to the
+\type {left} (or \type {right}) directive we can use \type {inner} or \type
+{outer} to force left or right placement depending in the spread.
+
+Instead of spoiling paper in the text areas, we can use the margin and edges:
+\type {leftmargin} and \type {leftedge}, \type {rightmargin} and \type
+{rightedge}, but also \type {innermargin} and \type {outermargin}, \type
+{inneredge} and \type {outeredge}.
+
+The next couple of pages we will highlight the margins and edges so that we can
+see what happens.

+
+The placement directives can be combined with setting distance and width
+parameters, thereby not only opening a world of possibilities, but also creating
+confusion. Therefore, we will illustrate these features by cloning floats.
+
+\startbuffer
+\definefloat
+  [marginfigure]
+  [figure]
+
+\setupfloat
+  [marginfigure]
+  [leftmargindistance=-\leftmargintotal,
+   default={left,none,low}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The definition command clones figure into a new class of figures. There are two
+ways to use such a float :
+
+\starttyping
+\placefloat
+  [marginfigure]
+  {} {\framed[width=1.5cm]{!}}
+\stoptyping
+
+or directly:
+
+\startbuffer
+\placemarginfigure
+  {} {\framed[width=1.5cm]{!}}
+\stopbuffer
+
+\typebuffer
+
+Both placement calls will result in a figure sticking into the margin.
+
+\getbuffer \fakewords{30}{40}
+
+By manipulating the margin distance, you can align graphics to vertical grid
+lines, like the edge:
+
+\startbuffer
+\definefloat
+  [edgefigure]
+  [figure]
+
+\setupfloat
+  [edgefigure]
+  [leftmargindistance=-\innercombitotal,
+   default={left,none,low,high}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \type {\innercombitotal} is one of the many available dimensions. This
+measure is the combined width of the margin and edge.
+
+\startbuffer
+\placeedgefigure
+  {} {\framed[width=1.5cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+\startbuffer
+\placeedgefigure
+  {} {\framed[width=\innercombitotal]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+You need to be aware of the fact that the margins and edges are not related to
+the backspace and cut space settings. When you set up a layout, you need to think
+of the right page as starting point. In a double sided layout, the margins are
+swapped in the page composition stage. Unless you explicitly go to a left or
+right page, you don't know if your left margin will be swapped or not.
+
+For this reason \CONTEXT\ provides the inner and outer margin|/|edge dimensions.
+These are automatically synchronized when the float is constructed. So, if you
+want to automatically adapt the float placement and width to the current left
+margin in a double sided document, you can use the inner dimensions.
+
+\starttabulate[||||]
+\NC dimension                  \NC left page
+                               \NC right page                 \NC\NR
+\NC \type{\outermarginwidth}   \NC \type{\leftmarginwidth}
+                               \NC \type{\rightmarginwidth}   \NC\NR
+\NC \type{\innermarginwidth}   \NC \type{\rightmarginwidth}
+                               \NC \type{\leftmarginwidth}    \NC\NR
+\NC \type{\outermargindistance}\NC \type{\leftmargindistance}
+                               \NC \type{\rightmargindistance}\NC\NR
+\NC \type{\innermargindistance}\NC \type{\rightmargindistance}
+                               \NC \type{\leftmargindistance} \NC\NR
+\stoptabulate
+
+Similar dimensions are available for the edges. You can save yourself some
+calculations by using the following dimensions:
+
+\starttabulate[|||||]
+\NC \type{\leftmargintotal}  \NC left  margin width \NC + \NC left  margin distance \NC\NR
+\NC \type{\rightmargintotal} \NC right margin width \NC + \NC right margin distance \NC\NR
+\NC \type{\innermargintotal} \NC inner margin width \NC + \NC inner margin distance \NC\NR
+\NC \type{\outermargintotal} \NC outer margin width \NC + \NC outer margin distance \NC\NR
+\stoptabulate
+
+As you may expect, the edge totals are available as well, which leave a few more
+totals, namely the combinations of margin and edge.
+
+\starttabulate[|||]
+\NC \type{\leftsidetotal}   \NC left  margin width \NC + \NC left  edge total \NC\NR
+\NC \type{\rightsidetotal}  \NC right margin width \NC + \NC right edge total \NC\NR
+\TB
+\NC \type{\innersidetotal}  \NC inner margin width \NC + \NC inner edge total \NC\NR
+\NC \type{\outersidetotal}  \NC outer margin width \NC + \NC outer edge total \NC\NR
+\TB
+\NC \type{\leftcombitotal}  \NC left  margin total \NC + \NC left  edge total \NC\NR
+\NC \type{\rightcombitotal} \NC right margin total \NC + \NC right edge total \NC\NR
+\TB
+\NC \type{\innercombitotal} \NC inner margin total \NC + \NC inner edge total \NC\NR
+\NC \type{\outercombitotal} \NC outer margin total \NC + \NC outer edge total \NC\NR
+\stoptabulate
+
+Adaptive back- and cutspace dimensions are also available:
+
+\starttabulate[|||||]
+\NC \type{\innerspacewidth} \NC adaptive backspace \NC\NR
+\NC \type{\outerspacewidth} \NC adaptive cutspace  \NC\NR
+\stoptabulate
+
+There is one drawback in using the inner and outer dimensions: if you also change
+the height of the float dynamically, you may end up in a kind of loop because a
+page break may occur at a non||expected place.
+
+While negative values move float into the margin, positive values will move the
+float into the text. It will be of no surprise that you can also set the right
+margin distance. Keep in mind that this distance is not related to the text
+margin, but to the float margin.
+

+
+As a result of manipulating the floats margin settings, the side floats can start
+in the margin (or edge). You should not confuse this with margin floats, i.e.\
+side floats that are explicitly placed in the margins.

+
+There are situations where you don't know the dimensions in advance. In order to
+prevent unwanted side effects, for instance part of a graphic disappearing
+outside the page boundary, \CONTEXT\ provides a few options. The most crude one
+is setting the \type {criterium}, as in:
+
+\starttyping
+\setupfloat
+  [figure]
+  [criterium=.25\textwidth]
+\stoptyping
+
+This will automatically turn figures that are wider than 25\% of the text width
+into normal floats instead of side floats. But let's not fall back on that
+feature now.
+
+You can use \type {maxwidth} and \type {minwidth} variables to control the
+placement in more detail. The exact result depends on the settings of \type
+{location}. By default we center, but you can set the location to \type {left} or
+\type {right} to achieve a different alignment.
+
+\startbuffer
+\definefloat
+  [midmarginfigure]

+\setupfloat

+\typebuffer \getbuffer \fakewords{30}{40}
+
+The meaning of \type {maxwidth} depends on the kind of float. First we place a
+left float with a width smaller than \type {maxwidth}.
+
+\start
+
+\startbuffer
+\setupfloat[figure][maxwidth=2cm]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\placefigure[left,none]{}{\framed[width=1cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+When the width exceeds the maxwidth, the float will be centered. This is because
+we have no reference alignment point.
+
+\startbuffer
+\placefigure[left,none]{}{\framed[width=5cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+In margin floats, the \type {maxwidth} settings have a different result. First we
+place a small graphic.
+
+\startbuffer
+\setupfloat[figure][maxwidth=\leftmarginwidth]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\placefigure[leftmargin,none]{}{\framed[width=1cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+Because the left and right margin of this document are the same |<|the edges
+differ|>| we don't need to use inner and outer dimensions.
+
+\startbuffer
+\setupfloat[figure][maxwidth=\leftmarginwidth]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+A wider than \type {maxwidth} graphic will behave like a mixture of a margin and
+text side float. Watch how we align the float to the margin.
+
+\startbuffer
+\placefigure[leftmargin,none]{}{\framed[width=5cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+\stop
+
+Instead of setting the width you can give \type {hanging} a try. The next
+examples demonstrate this.
+
+\startbuffer
+\placefigure[leftmargin,hanging,none]{}{\framed[width=5cm]{!}}
+\stopbuffer
+

+
+You can move down|/|up margin floats with the \type {\movesidefloat} macro. Such
+shifts come in handy when you have multiple side floats near to each other.
+
+\startbuffer
+\movesidefloat [+2*line]
+\placemidmarginfigure {} {\framed{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}
+
+Given the default placement template, this is equivalent to the following
+command. Watch out, a simple \type {line} has a different effect (alignment).
+
+\starttyping
+\placemidmarginfigure
+  [leftmargin,none,+2*line]
+  {} {\framed{!}}
+\stoptyping
+
+Another nice keyword is \type {long}:
+
+\startbuffer
+\placefigure
+  [leftmargin,none,long]
+  {} {\framed[height=2cm,width=2cm]{!}}
+
+Watch how we move down. The effect is that we skip over the margin figure.
+
+\placefigure
+  [leftmargin,none]
+  {} {\framed[height=1cm,width=2cm]{!}}
+\stopbuffer
+
+\typebuffer \getbuffer \fakewords{30}{40}

+\startbuffer
+\placefigure
+  [leftmargin,none]

+
+Do we clash or not?
+
+\placefigure
+  [leftmargin,none]
+  {} {\framed[height=2cm,width=2cm]{!}}
+
+Did we clash or not?
+\stopbuffer
+
+\typebuffer \getbuffer
+
+There are a few macros that can be of help with solving clashes in side floats:
+
+\starttabulate
+\NC \tex {flushsidefloats} \NC
+    This macro moves down as much as is needed to separate the side floats of
+    each other. \NC \NR
+\NC \tex {forgetsidefloats} \NC
+    this macro kind of forgets that a side float is in progress. \NC \NR
+\stoptabulate
+
+Use these macros with care. If you change the dimensions of the graphic and|/|or
+content involved, reconsider the use of these directives.
+
+The next couple of spreads we will demonstrate some example definitions. These
+placements are taken from one of the styles we made for typesetting a series of
+school math books which illustrations and tables all over the pages.
+
+First we fine tune the spacing around side floats and verbatim text.

+
+The placements have rather verbose names. In this case the word \quote {edge} is
+used to identify bleeding floats (with an cut||off margin of 3mm). The \quote
+{text} floats are side floats positioned in the main text flow.

+At \CONTEXT\ and Bacho\TEX meetings it is now a tradition that Harald König and I
+spend some time on figuring out what happens with border cases and interfences
+with user intervention. As it's hard to nail down I decided to add some more
+tracing and control. So, the remainder of this chapter is dedicated to Harald.
+
+We will now demonstrate some features in a way that makes it possible to
+compare to the simple default case. Options can be passed as keywords:
+
+\starttyping
+\placefigure
+  [left,...]
+  [fig:whatever]
+  {caption}
+  {content}
+\stoptyping
+
+or as settings:
+
+\starttyping
+\startplacefigure
+  [default={left,...},
+   title=caption,
+   reference=fig:whatever]
+
+    content
+
+\stopplacefigure
+\stoptyping
+
+It is important to realize that all that spacing can interfere with additional
+hard coded corrections at the users end. We don't show the effects of \type
+{sidespacebefore} and \type {sidespaceafter}, the two general vertical spacing
+hooks. These are currently set to {\tttf \rootfloatparameter {sidespacebefore}}
+and {\tttf \rootfloatparameter {sidespaceafter}} respectively. The \type
+{sidealign} parameter is always winning from a keyword doing the same.
+
+The last few examples demonstrate that you can define an instance. Often that's
+the best way to deal with special cases in a consistent way. For instance:
+
+\starttyping
+\definefloat
+  [LeftTwo]
+  [figure]
+
+\setupfloat
+  [LeftTwo]
+  [default=left,
+   sidealign=line]
+\stoptyping
+
+First we show some keyword variant, next some parameter driven versions.

+
+In \in {figure} [fig:side:one:1] and \in {figure} [fig:side:one:2] you see the
+first two pages of the typeset result.
+
+The anchor to the text is showed in orange and an optional shift in red. The content
+is in green and a depth compensation in magenta. Dummy lines added for proper
+spacing as well as progressing beyond a previous float are in blue.

+Progressing next to a side float and determining how many lines to indent is a
+somewhat complex mechamism because many factors play a role and spacing can
+interfere badly. The decision about the number of lines to hang is to some extend
+controllable but there are cases when you need to steer it (for instance by
+scaling an image). In the next overviews we see the result of the following
+somewhat complex setup:
+
+\typebuffer[three]
+
+The \type {step} parameter controls how we fill up the space when we need to
+progress beyond it for instance because another float shows up or because we
+issue a \type {\flushsidefloats}. Its value can be \type {big}, \type {medium} or
+\type {small} and defaults to \type {small} which gives of enough precision. The
+\type {sidethreshold} parameter controls the number of lines that we hang around
+the float. Here we only show the consequence of the the threshold. A larger
+threshold result in mode whitespace below the side float. You can zoom in to see
+what happens at the bottom of the float (or run the examples yourself).

+
+In this manual we pay quite some words on ways to snap your content on a grid.
+When dealing with grids, we often run into conflicting situations where we have
+to make the best of it. Let's again deal with an aspect of graphics.
+
+One of the strong points of \TEX\ is that it can deal with graphics
+automatically, which means that you seldom have to tweak dimensions or placements
+unless \unknown\ you're dealing with grids. In that case you need to make sure
+that the height of graphics consistently match the height of lines (or multiples
+of lines). It is for this purpose that the graphic inclusion macro has a \type
+{grid} entry.
+
+We will illustrate its usage using a dedicated figure class where we have set the
+space between figure and caption to zero.
+
+\startbuffer
+\definefloat[tightfigure][tightfigures][figure]
+\setupcaption[tightfigure][inbetween=]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \type {grid} parameter controls rounding of the height of a graphic in the
+following way:
+
+\starttabulate
+
+\NC \type {yes}    \NC safe rounding to an equal number of lines        \NC \NR
+\NC \type {fit}    \NC tight rounding to an equal number of lines       \NC \NR
+\NC \type {height} \NC same as \type {yes} but incremented by linedepth \NC \NR
+\stoptabulate
+
+On the next pages we demonstrate the effects of these settings. At the bottom of
+a page we show the placement commands. On the last pages we've hidden the
+captions with:
+
+\starttyping
+\setupfloat[tightfigure][default={here,none}]
+\stoptyping
+
+As you will notice, the \type {height} option is handy when the caption is
+positioned directly under the graphic.

+
+On the \CONTEXT\ mailing list, occasionally a user asks if we can post a complete
+document with the associated style. One reason for not honouring this request is
+that we want users to cook up their own styles. Besides that, there are a couple
+of styles in the regular \CONTEXT\ distribution.
+
+When browsing through this document, a \CONTEXT\ user may wonder what style was
+used to achieve its look and feel. We hope that while reading the text and
+playing with the examples, the reader will accomplish the skills to define more
+than just simple layouts.
+
+This document is not easy reading. Occasionally we spend some time explaining
+features not described in other manuals. The design of this document is to a
+large extent determined by its purpose, and as a result not always functional.
+For instance, we typeset on a grid which doesn't look too good. Also the order of
+presenting features, tips and tricks is kind of random and unstructured. The idea
+is that the visual effects will draw you to the right trick. Also, if you really
+want to benefit from these features, there is no way but to read the whole story.
+
+In spite of all its shortcomings, I hope that you enjoy reading this (yet
+unfinished) manual. Keep in mind that this manual is far from finished.

+\startchapter[title={Ornaments everywhere}]
+
+The background mechanisms present in \CONTEXT\ have evolved over time and with
+computers becoming faster, you can expect new functionality to show up and
+existing functionality to start using this technology. A simple background
+consist of a colored area. Many commands accept settings like:
+
+\starttyping
+...[background=color,backgroundcolor=red,backgroundoffset=3pt]
+\stoptyping
+
+Instead of such an area you can define one or more so called
+overlays:
+
+\starttyping
+\defineoverlay[one][...]
+\defineoverlay[two][...]
+
+...[background={one,two}]
+\stoptyping
+
+The name overlay comes from the fact that you stack them on top of each other. A
+special overlay is \type {foreground}, and deep down in \CONTEXT\ there are more
+predefined overlays.
+
+In the \METAFUN\ manual you will find example of usage, so here we stick to a
+simple code snippet for testing this functionality:
+
+\startbuffer
+\defineoverlay[one][\green A]
+\defineoverlay[two][\red   B]
+
+\framed[background=one]       {1}
+\framed[background={one,two}] {1---2}
+\stopbuffer
+
+\typebuffer
+
+The rather ugly result is:
+
+\startlinecorrection
+\hbox{\getbuffer}
+\stoplinecorrection
+
+You can construct overlays by using \TEX\ boxing primitives or commands like
+\type {\framed}. Alternatively you can use another mechanism: layers. Layers
+collect content and flush that when asked, for instance when an overlay is
+constructed. Layers can be independent of a page, or bound to a specific page
+number, left or right hand pages. Here we look at independent layers.
+
+All these mechanisms are fine tuned for cooperating with the output routine (the
+part of \TEX\ that deals with composing pages) and are well interact quite well
+with \METAPOST\ graphics. Details of usage and tricks are revealed in this manual
+as well as in styles that come with \CONTEXT. In this chapter we will apply
+layers to graphics. For this we need a few setups, like:
+
+\starttyping
+\setupbackgrounds
+  [page]
+  [background=pagegraphics]
+\stoptyping
+
+Here we have set up the page background to use an overlay called \type
+{pagegraphics}. However, instead of an overlay, we will use a layer. This layer
+will collect content that goes into the page background. Whenever a layer is
+defined, an overlay is automatically defined as well.
+
+\startbuffer
+\definelayer
+  [pagegraphics]
+  [x=-2mm,
+   y=-2mm,
+   width=\paperwidth,
+   height=\paperheight]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+When you fill a layer with content, you can influence the placement with the
+\type {x} and \type {y} parameters as well as \type {hoffset} and \type
+{voffset}, whichever you prefer. The reference point and alignment are set with
+\type {corner} and \type {location}.
+
+Live can be made easier by using presets, especially for our intended usage. The
+following presets are predefined.
+
+\startbuffer
+\definelayerpreset
+  [lefttop]     [corner={left,top},    location={right,bottom}]
+\definelayerpreset
+  [righttop]    [corner={right,top},   location={left,bottom}]
+\definelayerpreset
+  [leftbottom]  [corner={left,bottom}, location={right,top}]
+\definelayerpreset
+  [rightbottom] [corner={right,bottom},location={left,top}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Because for this layer we have also preset the \type {x} and \type {y}, those
+corners are laying a few millimeters outside the page area. We have preset the
+size as well, otherwise all corners would end up in the top left corner.
+
+We will now fill this layer. Because the layer is hooked into the page, it will
+be flushed when the page is constructed. After the page is written to the output
+file, the layer is emptied, unless its \type {state} is set to \type {repeat}.
+
+\startbuffer
+\setlayer [extras] [preset=lefttop]     {\externalfigure[hacker]}
+\setlayer [extras] [preset=righttop]    {\externalfigure[hacker]}
+\setlayer [extras] [preset=leftbottom]  {\externalfigure[hacker]}
+\setlayer [extras] [preset=rightbottom] {\externalfigure[hacker]}
+\stopbuffer
+
+\testpage[5] \typebuffer \getbuffer
+
+Once you got the picture of layering, you will start using this mechanism for all
+kind of tasks. Instead of putting layers in a background, you can also directly
+place them, by using one of the two (equivalent) commands:
+
+\starttyping
+\composedlayer{identifier}
+\placelayer[identifier]
+\stoptyping
+
+Layer are quite convenient for defining title pages, colophons, and special
+section heads, especially in combination with \type {\framed}.
+
+On top of the layer mechanism we have build a few more mechanisms, like
+ornaments. You can use ornaments to annotate graphics in such a way that the
+dimensions stay unchanged.
+
+\startbuffer
+\defineornament
+  [affiliation]
+  [rotation=90,corner={right,bottom},location={right,top},
+   hoffset=-.25ex]
+  [frame=on,background=color,backgroundcolor=red,offset=0pt]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The negative offset will overlay the text outside the graphic. The meaning of the
+sign of coordinates and offsets depends on the corner. \in {Figure} [fig:affi-1]
+shows the result. We have put the reference point in the right bottom corner. The
+ornament is anchored at the right top corner of the dot you can picture at the
+reference point. The ornament is shifted .25ex outwards.
+
+\starttyping
+\placefigure
+  {}
+  {\affiliation{graphic}{\externalfigure[hacker][width=3cm]}}
+\stoptyping
+
+\placefigure
+  [here] [fig:affi-1] {Number 1}
+  {\affiliation{graphic}{\externalfigure[hacker][width=3cm]}}
+
+There are two ways to handle the placement. Alternative \type {a} will change the
+dimensions of the graphic according to the size of the ornament, while
+alternative \type {b} acts as a pure overlay. In \in {figure} [fig:affi-2] the
+ornament is not taken into account when calculating the dimensions of the
+graphic. This is often the preferred placement, because this way the (often
+small) ornament will not it will not spoil visual alignment of similar graphics.

+
+\placefigure
+  [here] [fig:affi-2] {Number 2}
+  {\affiliation{graphic}{\externalfigure[hacker][width=3cm]}}

+A positive offset will place the ornament on top of the graphic (see \in {figure}
+[fig:affi-3]).

+
+There are several methods to construct title pages, headers, and other
+compositions. Of course there are the low level box constructors like \type
+{\hbox}, \type {\vbox} and positioning primitives like \type {\hskip}, \type
+{\hfill} and alike.
+
+Another option is to fall back on the low level box macros in the \CONTEXT\
+support file \type {supp-box} or the higher level \type {\framed} macro. You can
+use \type {\framed} nested and by cleverly using the offsets and dimensions you
+can do a lot.
+
+Layers are another means. You can or instance construct a title page in the
+following way:
+
+\starttyping
+\definelayer
+  [titlepage]
+  [width=\textwidth,
+   height=\textheight]
+
+\setlayer
+  [titlepage]
+  [preset=righttop,location={left,bottom},y=1cm,x=1cm]
+  {\definedfont[Regular at 60pt]Welcome}
+
+\setlayer
+  [titlepage]
+  [preset=rightbottom,location={right,top},y=2cm,x=2cm]
+  {\definedfont[Regular at 30pt]By Me}
+\stoptyping
+
+This just fills the layer. Placement is done with:
+
+\starttyping
+\startstandardmakeup
+  \flushlayer[titlepage]
+\stopstandardmakeup
+\stoptyping
+
+or alternatively:
+
+\starttyping
+\setupbackgrounds[text][background=titlepage]
+\startstandardmakeup \stopstandardmakeup
+\setupbackgrounds[text][background=]
+\stoptyping
+
+Another way to collect content is to use a collector. A collector starts out
+empty with:
+
+\startbuffer
+\definecollector[test][state=repeat]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can now stepwise fill this collector. For educational purposes we've turn of
+tracing so that you can see what the anchor points.
+
+\startbuffer
+\setcollector[test]
+  [location={right,bottom}]
+  {\externalfigure[detcow][frame=on,width=3cm]}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+\startbuffer
+\setcollector[test]
+  [corner={right,bottom},location={left,top}]
+  {\framed[background=color,backgroundcolor=tyellow]{this is a cow}}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+\startbuffer
+\setcollector[test]
+  [corner={right,bottom},location={right,bottom}]
+  {\framed[background=color,backgroundcolor=tblue]{that's for sure}}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+\startbuffer
+\setcollector[test]
+  [corner={left,top},location={left,top}]
+  {\framed[background=color,backgroundcolor=tgreen]{a dutch cow}}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+\startbuffer
+\setcollector[test]
+  [corner=middle,
+   location=middle]
+  {\framed[background=color,backgroundcolor=tred]{nearly done}}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+In addition to the parameters shown here, you can also provide additional ones:
+\type {x}, \type {y}, \type {offset}, \type {hoffset} and \type {voffset} for
+positioning and \type {rotation} for (as expected) rotating the content in steps
+of 90 degrees. As with layers, the coordinates and offsets can be used
+intermixed.
+
+\startbuffer
+\setcollector[test]
+  [hoffset=4cm,
+   voffset=-1cm,
+   corner=middle,
+   location=middle]
+  {\framed{now}}
+\stopbuffer
+
+\typebuffer {\traceboxplacementtrue \getbuffer}
+
+\startlinecorrection[blank] \flushcollector[test] \stoplinecorrection
+
+We can show the intermediate results because we have set the state of this
+collector to repeat. In this case you need to erase the content manually, using:
+
+\startbuffer
+\resetcollector[test]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The chapter titles of this document are (as usual in a \CONTEXT\ document)
+typeset by the \type {\chapter} macro. When thinking about implementing a non
+standard head, those familiar with \CONTEXT's head macros will probably first
+think of using one of the hooks, like:
+
+\starttyping
+\setuphead[chapter][command=\MyChapterHead]
+\stoptyping
+
+Here we have followed a different approach. First we set up the chapter head. The
+\type {empty} directive instructs \CONTEXT\ not to place the head itself, but
+still to include the associated data in the text stream. This means that we will
+not see a chapter title, but that there will be an entry in the table of
+contents, that references will be set up, that so called marks will be available,
+etc.
+
+\starttyping
+\setuphead
+  [chapter]
+  [placehead=empty,
+   header=chapter,
+   style=\BigText,
+   numberstyle=\BigNumber]
+\stoptyping
+
+The \type {header} parameters instructs the head handler to mark this page as
+special with regards to header texts. This text is set up as follows:
+
+\starttyping
+\definetext
+  [chapter]
+  [header]
+  [\setups{chapter}]
+  []
+\stoptyping
+
+The setups are just series of typesetting instructions. For the sake of
+readability, we have split them up.
+
+\starttyping
+\startsetups chapter
+  \setups[chapter:title]
+  \setups[chapter:number]
+  \setups[chapter:finish]
+\stopsetups
+\stoptyping
+
+The setups will use a dedicated layer for the chapter title:
+
+\starttyping
+\definelayer
+  [chapter]
+  [width=\dimexpr\makeupwidth+\cutspace\relax,
+   height=\headerheight]
+\stoptyping
+
+The following code uses a macro \type {\setlayerframed}. This is a combination
+between \type {\setlayer} and \type {\framed}. We use two placement macros to
+typeset the title and number. When doing so, we need to take care of both
+numbered chapters and unnumbered titles.
+
+\starttyping
+\startsetups chapter:title
+
+  \setlayerframed
+    [chapter]
+    [x=\dimexpr\makeupwidth+\cutspace\relax,location={left,bottom}]
+    [height=\headerheight,
+     foregroundcolor=white,

+As the title of this manual suggests: it's in the details. Most of our time is
+spent in optimizing spacing issues. If you're designing the layout yourself, for
+a large part you can fall back on the consistent spacing provided by \TEX, i.e.\
+think in terms of \type {em}'s, \type {ex}'s and fractions or multiples of \type
+{\bodyfontsize}, as well as base you're dimensions on those provided by the
+layout. When dealing with translating a \DTP\ layout into something \TEX,
+definitions like the above will often look more messy.

+In desk top publishing applications the grid is pretty dominant in defining
+layouts. On the other hand, \TEX\ is pretty good defining layouts in terms of
+relative dimensions. This means that mapping a desk top publishing layout into
+its \TEX\ (or \CONTEXT) counterpart takes some effort. For what it's worth,
+personally I don't like grids that much, specially not in complex documents,
+unless one makes sure that all elements are suitable sized for the grid used.
+
+We not only have to deal with vertical grids, but also with horizontal ones. Here
+we focus on the second category. When implementing designs, it is best first to
+look into the normal page layout areas. For most documents these are sufficient,
+but occasionally we need a more detailed approach.
+
+When playing with grids, you need to make sure that grid snapping is turned on.
+It helps if you turn on the grid so that you can see where things end up. When a
+horizontal grid is defined, gray vertical rules show their boundaries.
+
+\starttyping

+
+The \type {\setuplayout} command has a few settings that have to do with so
+called pseudo columns. These are in no sense related to multi|-|column
+typesetting and only play a role in placing text on specific locations.
+
+\starttyping
+\setuplayout
+  [columndistance=12pt,
+   columns=3]
+\stoptyping
+
+You can use \type {\layoutcolumnoffset} for positioning relative to the left
+boundary of the running text:
+
+\startbuffer
+\hskip\layoutcolumnoffset{2}{\red Text positioned in column 2!}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This mechanism is actually meant to ease the definition of complicated (title)
+pages where many text and graphic elements need to be anchored at well defined
+places. The layer mechanism is the most natural candidate for this.
+
+\startbuffer
+\definelayer [text] \setupbackgrounds [text] [background=text]

+\typebuffer
+
+When anchoring elements on a layer, you can specify absolute positions using the
+\type {x} and \type {y} keys but grid based positioning is possible with the
+\type {column} and \type {line} keys. We need to pass \type {grid} as location
+specifier.
+
+\startbuffer
+\setlayer[text][column=1,line=48,location=grid]{these are not}
+\setlayer[text][column=2,line=47,location=grid]{real columns}

+
+\typebuffer \getbuffer
+
+The data that goes into the layer is collected and flushed as soon as \TEX\
+builds the page. The buffer associated to the layer is then ready for new data
+(for the next page).
+
+In this example, you can see that the baselines of the boxes (here visualized by
+dashed rules) are put at the specified lines. You can use the \TEX\ box commands
+\type {\vbox}, \type {\vtop} and \type {\vcenter} to specify where the main
+baseline of the box content is positioned (at the top or bottom line, or
+centered).

+\page
+
+On the previous page we demonstrated a more complicated call to \type {\setlayer}
+and more features will be introduced in later chapters. We position the framed
+text in column~2 and at line~48. In addition we shift the text over the pseudo
+column width, i.e. we position the text at the right of the column. The location
+specifier aligns the text left from the point of positioning.
+
+When we have set up the pseudo columns, we have access to a couple of variables:
+
+\starttabulate[|l|l|l|]
+\NC \type {\layoutcolumns}         \NC counter   \NC number of columns    \NC \NR
+\NC \type {\layoutlines}           \NC counter   \NC number of gridlines  \NC \NR
+\NC \type {\layoutcolumnwidth}     \NC dimension \NC width of one column  \NC \NR
+\NC \type {\layoutcolumnoffset{n}} \NC macro     \NC position of column n \NC \NR
+\stoptabulate
+
+This is typically a feature that has been there for quite a while but that I forget
+about. It's probably because I never have to use grids myself.

+
+The grid snapper in \MKIV\ is quite different from the one in \MKII. For not too
+complex layouts the old grid snapper was quite ok, but the new one should be a
+bit more robust. In the old situation the running text was assumed to fit on the
+grid and the normal baseline skip should do the job in combination with the grid
+aware spacing features and placement mechanisms like tables and figures.
+
+Snapping on a fixed grid is sort of counter intuitive in \TEX\ because it has an a
+advanced spacing model with glue. Publishers however love grids so we do need to
+support it. Of course when complex layouts are involved in a later stage of
+document preparation the grid is often abandoned. This manual uses the grid but I
+personally never use the grid. There are better ways to make your document look
+good and often a grid snapped document doesn't look that great anyway, because
+all elements should somehow fit in multiples of the line height.
+
+The \MKIV\ snapper does more analysis and therefore can compensate for the more
+nasty cases. Of course it can still fail but we hope to fix those cases when we
+run into them. Grids are controlled by keywords or a combination of them.

+
+As you can see, keys like \type {maxdepth} can take a criterium as extra detail,
+separated by a colon. These options look obscure and often you need to trial and
+error a bit to get what you want. This is no real problem because most cases are
+handles automatically. Only headings and structuring elements that exceed a
+line height might need some treatment. For instance you might want to be more
+tolerant for (fractions of) a point overflow or when you know that always a blank
+follows you can decide to limit the height of some element to a line. Some of
+the options, like \type {math} and \type {middle} are used internally.
+
+On the next pages we show how the \type {maxheight} and \type {maxdepth}
+fractions work on a sample line.

+We now come to the topic of this chapter: snapping heads. The problem with
+section heads is that they often exceed the line height. Even worse, they can
+be more than one line high.
+
+The next pages show some ways to control snapping around heads. The result can be
+confusing, even when we use a font that we assume behaves like a regular style.
+For instance in Latin Modern the bold style has larger heights and depths than
+the regular style and even 0.1pt can force the snapper to add a line. The
+examples use that font.
+
+The grid option of \type {setuphead} normally takes one keyword that refers to
+the local snapper. However, the result gets then snapped again. This is because
+the local snapper can use a different line height. Historically the local snapper is
+the default but you can force global snapping by prefixing with the \type
+{global} keyword. The next table summarizes the ways you can control snapping:
+
+\starttabulate

+\NC \type {local}      \NC local snapping plus global snapping \NC \NR

+\starttextbackground[intro]
+A rather common way to draw attention to a passage, is to add a
+background. In this chapter we will therefore discuss how to enhance your
+document with \starttextbackground [subintro] those colorful areas that either
+or not follow the shape of your paragraph. \stoptextbackground\ Be
+warned: this chapter has so many backgrounds that you might start to
+dislike them.
+\stoptextbackground
+\stopbuffer
+
+\getbuffer[setup-a,setup-b,demo-a]
+
+\blank
+
+In the previous paragraph we demonstrated two important features of the
+background handler: you can nest backgrounds and backgrounds can be tight or
+wide. Features like this will often be used in combination with others, like
+special section headers. The raw coding of the previous paragraph is therefore
+not representative.
+
+\typebuffer[demo-a]
+
+The outer background commands is defined as follows:
+
+\typebuffer[setup-a]
+
+Here, the \type {paragraph} option ensures that the background covers the width
+of the body text. The inner background is defined in a similar way, but this time
+we choose \type {text} location.
+
+\typebuffer[setup-b]
+
+In this document we use protruding characters (hanging punctuation) so we've
+chosen a rather large offset, one that also matches the rest of the page design.
+
+Those who are familiar with the way \TEX\ works will probably see what problems
+can occur with backgrounds like this. What happens for instance when we cross
+page boundaries, and how will more complicated paragraph shapes be handled?
+
+The current implementation tries to handle page breaks and paragraph shapes as
+good as possible. This works well in normal one||column mode as well as in
+columns.

+
+\starttextbackground [A]
+  In this example, the paragraph shape is determined by the graphic placed
+  left of the text.
+    \starttextbackground [B]
+      This feature is implemented using the \type {\hangindent} and \type
+      {\hangafter} primitives, which means that we need to keep track of
+      their state. In addition, we need to handle the indentation directives
+      \type {\leftskip}, \type {\rightskip} and \type {\parindent}.
+    \stoptextbackground\
+  Because backgrounds end up in a different background overlay, nesting
+  them is no problem, and it is even possible to move them to the front
+  and back, as we will demonstrate later on. While the mechanism discussed
+  here will always be improved when we find border cases, the fundaments
+  it is built upon are quite stable.

+information.

+Unless you mess around too much with boxes, backgrounds work as expected in most
+situations. According to the Merriam||Webster on the authors laptop:
+
+\startbuffer
+\starttabulate[|l|p|l|]
+\NC background \NC \starttextbackground [A] the part of a
+    painting representing what lies behind objects is the

+\TB [halfline]
+\NC foreground \NC \starttextbackground [A] the part of a

+This is coded similar to normal running text. A table like this is in a way still
+part of the text flow. As floating body (see \in {table} [tab:back]) it can
+virtually end up everywhere. We add a frame to make clear where the boundaries are.
+
+\start
+
+    \setupfloat
+      [table]
+      [frame=on,framecolor=red,rulethickness=1pt]
+
+    \placetable

+
+    Keeping track of the state of a paragraph in a table in combination with
+    background is not entirely trivial. The current implementation evolved from
+    less clever ones and, unless you start doing complicated box manipulations
+    with the float content, works quite well. One reason why we made backgrounds
+    work in tables (and especially floating tables) is that is was needed for
+    typesetting books for primary and secundary education. In there, we want to
+    be able to hide the answers that students are supposed to fill in.

+In \in {figure} [fig:columns:1] you can see an advanced example of backgrounds
+running over columns. If you look carefully, you will notice that the background
+depends on the kind of background at hand:
+
+\startitemize[n,packed]
+\item the text starts and flows on
+\item the text flows on (or stands alone)
+\item the text flows on and ends
+\stopitemize

+This information is available when you want to draw your own backgrounds. Here

+
+The complexity of the backgrounds mechanism is partly due to the fact that we
+want to use arbitrary \METAPOST\ code to render the background. For instance, we
+want to have a proper shape so that not only the filled shape but also the drawn
+shape comes out right. You can compare this to a glyph in a font: when rendered
+filled the outline can be anything as it will not be drawn but when we use the
+outline we can run into overlaps and such. Where glyphs can use the odd|-|even
+filling methods, background can only use that for simple cases.
+
+When a background is rectangular it's all quite easy but as soon as some holes
+occur we need to do more work. Holes can be the result of a image placed next to
+the running text, or an image flushed at a page break or in the middle of a
+background. Paragraph shapes are another example. Backgrounds can cross page
+boundaries too. Yet another property is nesting and in such cases the shape is
+a bit more complex as we cross lines partially.
+
+In \MKII\ the background mechanism already was quite useable but it had some
+limitations. Calculating the background was mostly delegated to \METAPOST\ which
+is reasonable. In \MKIV\ some work is delegated to \LUA\ instead but that doesn't
+mean that the code is cleaner or easier to understand. So, to summarize, there
+are several cases that we need to take into account, like:
+
+\startitemize
+    \startitem
+        A background can run behind a paragraph in which case the start is
+        leftmost and end rightmost. In this case inserts (like floats) have to be
+        dealt with after the shape has been calculated.
+    \stopitem
+    \startitem
+        A background can be in|-|line (the \type {text} location variant) in
+        which case we need to follow the paragraph shape, if set. In that case we
+        have a mix of calculating the background shape and afterwards
+        compensating for inserts.
+    \stopitem
+    \startitem
+        A third case is tabulation and tables where we have dedicated regions to
+        deal with. When these float we need to make sure that the backgrounds are
+        adapted to the where they end up.
+    \stopitem
+    \startitem
+        Yet another case is in columns, where we hape multiple regions to deal
+        with.
+    \stopitem
+    \startitem
+        As mentioned, floats need special treatment and they can be part of the
+        page flow but also end up left or right of the text (either or not
+        shifted) but also in the margins, edges, back- or cutspace. Their
+        placement influences the way backgrounds are calculated so additional
+        information needs to travel with them.
+    \stopitem
+
+\stopitemize
+
+We distinguish between a paragraph background, which runs between the left and right skip
+areas and a text background which follows a shape. In \in {figure} [fig:columns:3] we see a
+test case with several such shapes.

+As often in \TEX\ coming up with a solution is not a the problem but interference
+is. You can cook up a solution for one case that fails in another. Backgrounds

+\startchapter[title={Tuning math formulas}]
+
+Because of its look and feel, a math formula can look too widely spaced when put
+on a grid. There are a few ways to control this. First of all, the default grid
+option bound to math is already more tolerant. But you can control it locally
+too. Take the following formula:
+
+\startbuffer
+\startformula
+  a = b^c
+\stopformula
+\stopbuffer
+
+\blank \fakeline \getbuffer \fakeline \blank
+
+This has been entered as:
+
+\typebuffer
+
+and because it is just a line of math it comes out as expected. The next code
+
+\startbuffer
+\startformula
+  a = \frac {a} {b}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+produces a higher line:
+
+\blank \fakeline \getbuffer \fakeline \blank
+
+as does:
+
+\startbuffer
+\startformula
+  a = \frac {\frac {b} {c}} {\frac {d} {e}}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+\blank \fakeline \getbuffer \fakeline \blank
+
+We will now demonstrate three ways to compensate fo rexcessive spacing. The first
+variant just sets a grid parameter:
+

+\typebuffer
+

+
+You can also pass this as an option. Only a few such grid related options are
+defined: \type {halfline}, \type {line}, \type {-halfline} and \type {-grid}.
+
+\startbuffer
+\startformula[-halfline]
+    a = \frac {\frac {b} {c}} {\frac {d} {e}}
+\stopformula

+\typebuffer

+\blank \fakeline \getbuffer \fakeline \blank
+
+If you need to compensate frequently you can consider defining an instance:
+
+\startbuffer
+\defineformula[tight][grid=math:-halfline]
+
+\starttightformula
+    a = \frac {\frac {b} {c}} {\frac {d} {e}}
+\stoptightformula
+\stopbuffer
+
+\typebuffer
+
+\blank \fakeline \getbuffer \fakeline \blank
+
+The result can be somewhat unexpected at the top and bottom of a page. When we
+subtract half a line from the height we can end up above the text area. This is
+where the \type {split} directive comes in. So, the compensations are actually
+defined as
+
+\starttabulate[|TCT{blue}|T|]
+\NC math            \NC \theexpandedsnapperset{math} \NC \NR
+\NC math:line       \NC \theexpandedsnapperset{math:line} \NC \NR
+\NC math:halfline   \NC \theexpandedsnapperset{math:halfline} \NC \NR
+\NC math:-line      \NC \theexpandedsnapperset{math:-line} \NC \NR
+\NC math:-halfline  \NC \theexpandedsnapperset{math:-halfline} \NC \NR
+\stoptabulate
+
+You can define your own variants building on top of an existing one:
+
+\starttyping
+\definegridsnapping[math:my][math,....]
+\stoptyping
+
+We demonstrate the effect of the \type {split} directive here. It triggers a
+check at the page boundaries but you need to keep in mind that this is not always
+robust as such boundaries themselves can be triggered by and inject anything.
+
+\startbuffer[a]
+\dorecurse {15} {
+    \startformula[grid={math,-halfline}]
+        a = \frac {\frac {b} {c}} {\frac {d} {e}}
+        (\hbox{top #1 default})
+    \stopformula
+    \blank[samepage]
+    \fakeline
+}
+\stopbuffer
+
+\startbuffer[b]
+\dorecurse {15} {
+    \startformula[grid={math,-halfline,split}]
+        a = \frac {\frac {b} {c}} {\frac {d} {e}}
+        (\hbox{top #1 compensated})
+    \stopformula
+    \blank[samepage]
+    \fakeline
+}
+\stopbuffer
+
+\getbuffer[a]
+\getbuffer[b]
+
+As said, the compensation is achieved with the \type {page} directive. The
+previous pages were rendered using:
+
+\typebuffer[a]
+
+and
+
+\typebuffer[b]
+
+In order to get a consistent result we keep the depth of the formula the same but
+effectively shift it down a bit, still honouring the grid. So what about the
+bottom.
+
+We can decide that the snapped formula doesn't fit and force a new page but we
+can also accept that it sticks out to the bottom, which is less worse than the
+top|-|of|-|the|-|page case.
+
+\startbuffer[a]
+\dorecurse{45}{\fakeline}
+\startformula[grid={math,-halfline}]
+    a = \frac {\frac {b} {c}} {\frac {d} {e}}
+    (\hbox{bottom default})
+\stopformula
+\stopbuffer
+
+\startbuffer[b]
+\dorecurse{45}{\fakeline}
+\startformula[grid={math,-halfline,split}]
+    a = \frac {\frac {b} {c}} {\frac {d} {e}}
+    (\hbox{bottom compensated})
+\stopformula
+\stopbuffer
+
+\page \getbuffer[a] % fits on the page
+\page \getbuffer[b] % forces a new page
+
+These mechanisms might be improved over time but as we don't use it frequently
+that might take a while.
+
+The following formula was posted at the \CONTEXT\ mailing list in a grid snapping
+thread and we will use it to demonstrate how you can mess a bit with the
+snapping.
+
+\startbuffer
+g(x_{*}) = \lim_{n\to\infty} g(a_{n}) \leq 0 \leq \lim_{n\to\infty} g(b_{n}) = g(x_{*})
+\stopbuffer
+
+\typebuffer
+
+We show the given grid parameter as well as its expansion into the low level grid
+directives.

+\startsection[title=Introduction]
+
+Not long after we released \LUATEX\ 1.0, we started experimenting a bit more with
+so called foreign function interface: \FFI. Originally that interface to external
+libraries was only available in \LUAJITTEX, but a good and compatible alternative
+is now also available in the normal engine too. For users it is not that relevant
+to know how it works, as long as it works. It means that in addition to \SWIGLIB\
+we have a method that doesn't demand compilation as it uses normal (public)
+libraries.
+
+Of course one needs to make sure that the right version of a library is used.
+And, as there is the danger of the \API\ having been changed in an incompatible
+way one can wonder if such a dependency is really what one wants. On the other
+hand one can expect \CONTEXT\ to keep up.
+
+Do you really need libraries? For instance does it really make sense to use curl,
+ghostscript or graphicmagic libraries while the command line version is
+(normally) just as efficient and avoids a dependency. This is even more true if
+you realizes that for instance a fetch or conversion only needs to happen once
+per run or in fact only when there is some change in the resource.
+
+On the other hand, when accessing databases one can avoid the often slower
+command line calls and save the hassle of intermediate files. Here efficiency
+wins. Also, when \CONTEXT\ is used in a high performance database backend
+application a distribution and the used libraries are not updated on a daily
+basis.

+
+Apart from some experiments we currently can use \FFI\ interfaced libraries in:

+\LL
+\stoptabulate
+
+The profiler that we occasionally use to identify bottlenecks in the engine (for
+instance when we upgrade \LUA) uses \FFI\ to provide access to the high resolution
+timers but this is typically different per platform.
+
+One problem with libraries, especially on \WINDOWS\ is that the library is found on
+some system path and it can happen that multiple programs ship the same library but in
+different versions. You can try to play safe and put libraries in the \TEX\ tree, for
+instance on my system they are in:
+
+\starttyping
+c:/data/tex-context/tex/texmf-win64/bin/lib/luatex/lua/whatever/libwhatever.dll
+\stoptyping
+
+You can trace where libraries are looked for with:
+
+\starttyping
+\enabletrackers[resolvers.ffilib]
+\stoptyping
+
+or in \LUA\ with:
+
+\starttyping
+trackers.enable("resolvers.ffilib")
+\stoptyping
+
+The library is first located on one of the valid \TDS\ paths (these are sort of
+standardized in \TEX\ distributions) and then using the normal \FFI\ loader.

+\section{Unscaled fences}
+
+The \type {\mathdelimitersmode} primitive is experimental and deals with the
+following (potential) problems. Three bits can be set. The first bit prevents
+an unwanted shift when the fence symbol is not scaled (a cambria side effect). The
+second bit forces italic correction between a preceding character ordinal and
+the fenced subformula, while the third bit turns that subformula into a ordinary
+so that the same spacing applies as with unfenced variants. Here we show Cambria
+(with \type {\mathitalicsmode} enabled).

+
+So, when set to 7 fenced subformulas with unscaled delimiters come out the same
+as unfenced ones. This can be handy for cases where one is forced to use \type
+{\left} and \type {\right} always because of unpredictable content. As said, it's
+an experimental features (which somehow fits in the exceptional way fences are
+dealt with in the engine). The full list of flags is given in the next table:

+\NC "04 \NC force a ordinary subformula \NC \NR
+\NC "08 \NC no shift when a base character \NC \NR
+\NC "10 \NC only shift when an extensible \NC \NR
+\stoptabulate

+The effect can depend on the font (and for Cambria one can use for instance \type

+
+We conform to the way other \TEX\ engines handle trailing tabs and spaces. For
+decades trailing tabs and spaces (before a newline) were removed from the input
+but this behaviour was changed in September 2017 to only handle spaces. We are
+aware that this can introduce compatibility issues in existing workflows but
+because we don't want too many differences with upstream \TEXLIVE\ we just follow
+up on that patch (which is a functional one and not really a fix). It is up to
+macro packages maintainers to deal with possible compatibility issues and in
+\LUATEX\ they can do so via the callbacks that deal with reading from files.
+
+The previous behaviour was a known side effect and (as that kind of input
+normally comes from generated sources) it was normally dealt with by adding a
+comment token to the line in case the spaces and|/|or tabs were intentional and
+to be kept. We are aware of the fact that this contradicts some of our other
+choices but consistency with other engines and the fact that in \KPSE\ mode a
+common file \IO\ layer is used can have a side effect of breaking compatibility.
+We still stick to our view that at the log level we can (and might be) more
+incompatible.

+
+There are many math symbols but never enough. Here is an example of how you can
+roll out your own. We start out with nothing:
+
+\startbuffer
+\definemathstackers
+  [nosymbol]
+  [voffset=\zeropoint,
+   hoffset=\zeropoint,
+   mathclass=ord,
+   topoffset=\zeropoint,
+   middlecommand=,
+   color=maincolor]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+You can now use this class of stackers:
+
+\startbuffer
+\startformula
+  \mathover [nosymbol] {"2217} {A}
+  \mathover [nosymbol] {"2218} {A}
+  \mathover [nosymbol] {"2219} {A}
+\stopformula
+\stopbuffer
+
+\typebuffer
+
+This looks like this:
+
+\getbuffer
+
+But we want proper math, which means an an italic nucleus, a properly placed
+accent, a shift of that accent matching the slope or the nucleus, so we actually
+need:
+
+\startbuffer
+\definemathstackers
+  [mysymbol]
+  [voffset=-.30\mathexheight,
+   hoffset=\zeropoint,
+   mathclass=ord,
+   topoffset=.4\mathemwidth,
+   middlecommand=\mathematics,
+   color=maincolor]
+\stopbuffer
+
+\typebuffer \getbuffer

+\startbuffer
+\startformula
+  \mathover  [mysymbol]{"2217}       {A}
+  \mathover  [mysymbol]{"2218}       {A}
+  \mathover  [mysymbol]{"2219}       {A}
+  \mathunder [mysymbol]       {"2217}{A}
+  \mathunder [mysymbol]       {"2218}{A}
+  \mathunder [mysymbol]       {"2219}{A}
+  \mathdouble[mysymbol]{"2217}{"2217}{A}

+  \mathdouble[mysymbol]{"2219}{"2219}{A}
+\stopformula

+
+We show both over and under variants:

+\typebuffer
+
+So this time we get:

+\startsection[title=Script kerning]
+
+Text in math is somewhat special. First of all, a math font is not a text fonts
+because the characters and glyphs have a different purpose. Text features are
+normally not present (and often not even wanted). Anyway, you can force a text
+font, but that doesn't mean you will get for instance kerning. You can force a
+box which in turn will trigger font processing, but then you normally loose the
+script related size properties. So we end up with some juggling possibly combined
+with user intervention, and that is what the \type {\text} macro does.
+
+But still there is the kern between a variable and its subscript to consider,
+something that normally is dealt with with staircase kerns, an \OPENTYPE\ math
+speciality. But, as we progress over the math list, and we bind a subscript to a
+variable, that subscript can be anything: a simple character, or more characters
+(a list) or something wrapped in a box. There is simply no universal solution
+that we can hard code because sometimes you don't want that special kerning. This
+is why in \LUATEX\ the integer variable \type {\mathscriptboxmode} controls the
+way this is dealt with.
+
+\starttabulate[|l|p|]
+\NC \type {0} \NC forget about kerning \NC \NR
+\NC \type {1} \NC kern math sub lists with a valid glyph (default in the engine) \NC \NR
+\NC \type {2} \NC also kern math sub boxes that have a valid glyph (default in \CONTEXT) \NC \NR
+\NC \type {3} \NC only kern math sub boxes with a boundary node present \NC \NR
+\stoptabulate
+
+Here we show some examples of how this parameter controls kerning. Watch the
+difference between a simple font switch and a text wrapped in a box. There are
+differences between fonts: some fonts have kerns, some don't. When present kerns
+are passed to the engine without further user intervention.

+
+When in text mode you enter a combination of combining accent and character, a
+composed character is assumed and often you then get one shape in your document.
+A similar feature is available in math mode. After some discussion and analysis
+of the potential clashes and confusion (thanks to Aditya Mahajan) we settled on a
+combination of methods: so called math lists entries that we entered in the
+character database and|/|or so called special sequences that are part of
+\UNICODE. In the next tables we use \type {ml} for math list and \type {sp} for
+specials. Collapsing mode \type {1} only uses the specials, while \type {2} first
+checks the specials and then the math lists, and \type {3} does the reverse.
+
+In the database you can find this (a few fields have been omitted):

+\startchapter[title=Things you might forget]
+
+\startsection[title=Ampersands]
+
+You can skip this, but if you continue reading, here is some low level plain code
+(don't use this in \CONTEXT):
+
+\starttyping
+\def\matrix#1%
+  {\null
+   \,
+   \vcenter
+     {\normalbaselines
+      \ialign{\hfil$##$\hfil && \quad\hfil$##$\hfil\crcr
+      \mathstrut\crcr
+      \noalign{\kern-\baselineskip}
+      #1\crcr
+      \mathstrut\crcr
+      \noalign{\kern-\baselineskip}}}%
+   \,}
+\stoptyping
+
+You see the \type {&} here and it's the alignment cell separator. The special
+meaning of these characters is determined by the so called catcode. Here we have:
+
+\starttyping
+\catcode"26=4
+\stoptyping
+
+Character \type {0x26} is the ampersand. In \CONTEXT\ this character can be used
+in text mode because we never use it as alignment character, which is something
+typical \TEX. The same is true for \type {^} and \type {_}. So, effectively we
+have (for instance):
+
+\starttyping
+\catcode"26=12
+\stoptyping
+
+In order to still get this \type {&} supported as alignment character in math
+mode, we have to jump through some hoops. Think of this (again, don't do this in
+\CONTEXT):
+
+\starttyping
+\bgroup
+    \global\mathcode"26="8000
+
+    \catcode"26=4
+
+    \xdef\normalmathaligntab{&}
+
+    \catcode"26=13
+
+    \global\everymath{\def&{\normalmathaligntab}}
+\egroup
+\stoptyping
+
+Before we go on you should realize that we never use the \type {&} in \CONTEXT\
+as separator. The sole reason for dealing with this issue is that users can have
+their own code that uses the ampersand that way. In \CONTEXT\ we do things like:
+
+\starttyping
+\startformula
+    \startmatrix
+        \NC 1 \NC 2 \NR
+        \NC 3 \NC 4 \NR
+    \stopmatrix
+\stopformula
+\stoptyping
+
+Where \type {\NC} can be more powerful than a \type {&}. Anyhow, the reason for
+discussing this here is that there can be surprises. In a running text you can do
+this:
+
+\starttyping
+A & B
+\stoptyping
+
+Which procces okay and gives the ampersand as glyph. The following is also okay:
+
+\starttyping
+$A \Umathchar"2"0"26 B$
+\stoptyping
+
+However, the next one:
+
+\starttyping
+$A \char"26 B$
+\stoptyping
+
+fails with a \type {Misplaced alignment tab character &}. The reason is that
+where in text mode \TEX's parser will turn the \type {\char} into a character
+node and carry on afterwards, in math mode it will treat this inpout as were it a
+directly input character, so the above is like, where the \type {&} has active
+properties and becomes the sparator ampersand which then triggers the error:
+
+\starttyping
+$A & B$
+\stoptyping
+
+This means that we cannot have a definition like:
+
+\starttyping
+\def\AND{\char"26\relax}
+\stoptyping
+
+that can be used in math mode, which is why the \CWEB\ macros do:
+
+\starttyping
+\def\AND{\def\AND{\mathchar"2026\relax}\AND}
+\stoptyping
+
+Back to the plain example. The \type {\matrix} command has to be wrapped in
+math mode and therefore the \type {&} will adapt, while in most \CONTEXT\
+constructs that use alignment, we're not in math mode at all when we start
+with the alignment. Therefore the \type {&} will be just an ampersand in most
+\CONTEXT\ cases.
+
+So to summarize: don't expect \type {\char"26} to work out well in math mode
+because all kind of magic kicks in. These are the more obscure features and side
+effects of \TEX\ dealing with input and it's really hard to predict how \TEX\
+will see the ampersand you entered. You need to know the internals and even then
+it's non trivial. Take
+
+\starttyping
+\startformula
+\startalign
+    \NC x \NR
+    \NC x \NR
+\stopalign
+\stopformula
+\stoptyping
+
+versus:
+
+\starttyping
+\startformula
+\startalign
+    & x \NR
+    & x \NR
+\stopalign
+\stopformula
+\stoptyping
+
+versus:
+
+\starttyping
+\startformula
+\startalign
+    \NC x & y \NR
+    \NC x & y \NR
+\stopalign
+\stopformula
+\stoptyping
+
+The first case works as expected, the second one treats the \type {&} as text and
+the third one, as we enter math mode with \type {\NC}, depends on circumstances.
+If you use just \CONTEXT\ math coding, you can say:
+
+\starttyping
+\setupmathematics
+  [ampersand=normal]
+\stoptyping
+
+And always render an ampersand (although a math one in math mode).

+\startsection[title=Multiline]
+
+Inline formulas can span lines but display math normally sits on one line unless
+one uses alignment mechanisms. Take this:
+
+\startbuffer[demo]
+\startformula
+    x\dorecurse{30}{ + #1x^{#1x}} = 10
+\stopformula
+\stopbuffer
+
+\typebuffer[demo]

+\par \start \setupformula[split=no]  \getbuffer[demo] \stop \par
+
+You can set \type {split} to \type {yes} using \type {\setupformula} and get the
+following:
+
+\par \start \setupformula[split=yes] \getbuffer[demo] \stop \par
+
+Maybe nicer is to also set \type {align} to \type {flushleft}:
+
+\par \start \setupformula[split=yes,align=flushleft] \getbuffer[demo] \stop \par
+
+If you want the binary operators to start the lines you can set this:

+\setupformulas[split=yes,align=flushleft]
+\stopbuffer

+
+Superscripts and subscripts are typeset in a smaller size than their nucleus. You

+
+You can put an accent over a character:
+
+\startbuffer
+$\grave{x} \neq \grave{i}$\quad
+$\ddot {x} \neq \ddot {i}$\quad
+$\bar  {x} \neq \bar  {i}$\quad
+$\acute{x} \neq \acute{i}$\quad
+$\hat  {x} \neq \hat  {i}$\quad
+$\check{x} \neq \check{i}$\quad

+$\tilde{x} \neq \tilde{i}$\quad
+$\dddot{x} \neq \dddot{i}$\quad

+\startsection[title=Introduction]
+
+Math support in \CONTEXT\ is wrapped around basic \TEX\ primitives and
+unfortunately not all we want is easy to configure. This is not surprising
+because the original ideas behind \TEX\ are that one makes a style per book and a
+one macro package \quote {we-can-do-it-all} approach is not what Don Knuth had in
+mind at that time.
+
+So, for instance support for configurable spacing per math element, coloring of
+specific (sub) elements, simple switching of whatever combination of alignments
+and number placement, these all take quite a bit of code and hackery.
+
+Even configuring something seemingly trivial as fractions or top, bottom, left,
+middle and right fences take some effort. This is because the engine uses
+information from fonts to combine shapes and paste the content and ornaments to
+together.
+
+For that reason already in \MKII\ but more extensively in \MKIV\ we did a lot of
+these things in wrapper macros. When the math renderer was finalized for
+\OPENTYPE\ math some extra control was added that can make these things easier.
+However, because we go a bit beyond what is possible using this new functionality
+these new mechanisms are not yet used in \MKIV, but they might be eventually.
+Here we just show some of the (newer) low level trickery. For details about what
+was already possible in pure \TEX, we refer to the ultimate references: the \TeX
+book (by Donald Knuth) and \TeX\ by Topic (by Victor Eijkhout).
+
+\stopsection
+
+\startsection[title=Kerning]
+
+Kerning in \OPENTYPE\ math is not the same as in traditional \TEX: instead of a
+single value, we have staircase kerns, that is, depending on the location (left
+or right) and the vertical position, at discrete distances between depth and
+height. In addition there is italic correction but that is only applied in
+certain cases, one of which is the script location.
+
+Unfortunately not all fonts follow the same route. Some fonts have a true width
+and a moderate italic correction is added to it (of at all), while other fonts
+lie about the width and depend on an excessive italic correction to compensate
+for that.

+I will not discuss the details because when a font gets updated, it might look
+better or worse. These fonts were loaded with the following directive set:
+
+\starttyping
+\enabledirectives[fontgoodies.mathkerning]
+\stoptyping
+
+An example of a fontgoodie that fixed the kerning is \type {pagella-math.lfg}. Here
+is the relevant bit:
+
+\starttyping
+local kern_200 = { bottomright = { { kern = -200 } } }
+local kern_100 = { bottomright = { { kern = -100 } } }
+
+return {
+  .....
+  mathematics = {
+    .....
+    kerns = {
+      [0x1D449] = kern_200, -- 𝑉
+      [0x1D44A] = kern_100, -- 𝑊
+    },
+    .....
+  }
+}
+\stoptyping
+
+This fixes the real bad kerning of Pagella Math which at least in 2017 was not
+(yet) fixed. When the fonts are frozen we can start makling permanent runtime
+fixes like this.

+\startsection[title=Primes]
+
+Primes are a pain in the butt. The reason for this is that they are independent
+characters on the one hand but can be seen as a superscript on the other. Let's
+first look at the symbols at the three sizes that are used in math.

+The first set is the normal prime character scaled to the text, script and
+scriptscriptsize. The second set shows the characters (at three sizes) as they
+are in the font. The largest character is raised while the other two are closer
+to the baseline. In some fonts the smaller sizes arenot smaller at all. The last
+set is a variant of the the first set but we made them into virtual characters
+with a displacement and different dimensions. Those are the ones we use as
+primes.

+Sometimes users complain about the look of a radical symbol. This is however a matter

+more straight up than relatives in another font. When largers sizes are needed, some
+fonts offer smaller than others. Just look at the different desings:

+\startsection[title=Integrals]
+
+A curious exception in the math system is the integral sign. Its companions are
+the summation and product signs, but integral has as extra property that it has a
+slant. In \LUATEX\ there is rather advanced control over how the (optional)
+scripts are positioned (which relates to italic correction) but in \CONTEXT\ we
+only make limited use of that. The main reason is that we also need to support
+additional features like color. Therefore integrals are handled by the extensible
+mechanism.
+
+The size of an integral is more of less fixed but you can enlarge to your
+liking. One reason for this is that you might want a consistent size across
+formulas. Let's use the following setup:
+
+\startbuffer[setup]
+\setupmathextensible
+  [integral]
+  [rightoffset=-1mu,
+   exact=yes,
+   factor=2]
+
+\let\int\integral
+\stopbuffer
+
+\typebuffer[setup]
+
+We use the following exmaple:
+
+\startbuffer[demo]
+\ruledhbox{$\integral                  f\frac{1}{2}           $}\quad
+\ruledhbox{$\integral[rightoffset=3mu] f\frac{1}{2}           $}\quad
+\ruledhbox{$\integral[exact=no]        f\frac{1}{2}           $}\quad
+\ruledhbox{$\integral                  f\frac{\frac{1}{2}}{x} $}\quad
+\ruledhbox{$\integral[exact=no]        f\frac{\frac{1}{2}}{x} $}\quad
+\ruledhbox{$\integral[factor=1]        f\frac{1}{2}           $}\quad
+\ruledhbox{$\integral[factor=3]        f\frac{\frac{1}{2}}{x} $}\quad
+\ruledhbox{$\integral[factor=3]        f\frac{1}{2}           $}\quad
+\ruledhbox{$\int                       f\frac{1}{2}           $}% bonus

+class fences. Actually there is no real middle class and spacing was somewhat
+hard codes when \type {\middle} was added to \ETEX. In \LUATEX\ we have
+introduced keywords to some primitives that control spacing and other properties.
+This permits better control over spacing than messing around with (for instance)
+injected \type {\mathrel} commands that can have their own side effects.

+
+\startintro
+
+Especially in interactive documents, adding backgrounds to the page and text
+areas not only enhances readability, but also makes it more convenient to
+identify header, footers and navigational areas. In this chapter we will
+demonstrate that with \METAPOST\ we can go beyond the \TEX\ based features
+present in \CONTEXT. One section is dedicated to graphics and printing,
+especially bleeding.
+
+\stopintro
+
+\startsection[title={The basic layout}]
+
+\index {layout}
+
+In the \CONTEXT\ manual you can find many details on the composition of the page.
+When \TEX\ typesets text, crossing the page boundary triggers \TEX's output
+routine. This routine is responsible for pasting the body text that goes onto a
+page in the correct area. A simple representation of such a page is:
+
+\startbuffer[a]
+\startuseMPgraphic{layout 1}
+  pickup pencircle scaled 1mm ;
+  fill unitsquare xyscaled (7cm,8cm)
+    withcolor .85white ;
+  fill unitsquare xyscaled (5cm,5cm) shifted (1cm,1.5cm)
+    withcolor .625yellow ;
+  fill unitsquare xyscaled (5cm,1cm) shifted (1cm,.5cm)
+    withcolor .625red ;
+  fill unitsquare xyscaled (5cm,1cm) shifted (1cm,6.5cm)
+    withcolor .625red ;
+  draw unitsquare xyscaled (5cm,7cm) shifted (1cm,.5cm)
+    withcolor .25white ;
+  drawarrow (2cm,8cm) -- top (2cm,7.5cm) ;
+  drawarrow (0cm,7cm) -- lft (1cm,7cm) ;
+  clip currentpicture to unitsquare xyscaled (7cm,8cm) ;
+\stopuseMPgraphic
+\stopbuffer
+
+\startbuffer[b]
+\startuseMPgraphic{layout 2}
+  \includeMPgraphic{layout 1}
+  clip currentpicture to unitsquare scaled 3cm shifted (0,5cm) ;
+  currentpicture := currentpicture scaled 2 shifted (0,-8cm) ;
+  setbounds currentpicture to unitsquare xyscaled (6cm,8cm) ;
+\stopuseMPgraphic
+\stopbuffer
+
+\getbuffer[a,b]
+
+\startbuffer[c]
+\startlinecorrection[blank]
+\hbox
+  {\useMPgraphic{layout 1}\hskip1cm
+   \useMPgraphic{layout 2}}
+\stoplinecorrection
+\stopbuffer
+
+\getbuffer[c]
+
+The red areas are the header and footer, while the yellow areas contains the text
+flow. We can turn headers on and off and|/|or hide them. For this reason, the
+header, text and footer areas together make up the height of the text.
+
+A close look at the left picture will reveal that the two arrows point to the
+center of the lines. This is achieved by the \type {top} and \type {lft}
+directives. If we would not have clipped the picture, the arrow would have stuck
+half a line width outside the gray area that represents the page. When
+constructing such pictures, one should really pay attention to such details,
+since it pays off in the overall look and feel of the document.
+
+The vertical arrow represents the top space, while the horizontal arrow denotes
+the distance to the back of the cover (back space). By changing their values, you
+can shift the main body text on the page. In a double sided layout scheme, the
+back space is automatically mirrored on even pages.
+
+An advanced \METAPOST\ user may wonder why we hard code the dimensions, and avoid
+\METAPOST's powerful mechanisms for defining relations. Our experience has taught
+us that in pictures like this, providing a general solution seldom pays large
+dividents or savings in time.
+
+\typebuffer[a]
+
+As you can see, the left graphic is defined as a series of rectangles. The \type
+{xyscaled} macro is part of the \CONTEXT\ files, and saves some typing and space.
+It is defined as a primary, requiring both left and right operands.
+
+\starttyping
+primarydef p xyscaled q =
+  p xscaled (xpart q) yscaled (ypart q)
+enddef ;
+\stoptyping
+
+Zooming in on the top left corner only takes a few lines. First we clip the
+correct part, next we scale it up, and finally we let the bounding box suit the
+left picture.
+
+\typebuffer[b]
+
+This code demonstrates how you can reuse a graphic inside another one. This
+strategy can easily be used to stepwise build (or extend) graphics. The two
+graphics were put side by side with the following command. Watch the use of line
+correction commands. They optimize the white space around the graphic.
+
+\typebuffer[c]
+
+As soon as you want to make an electronic document, you will want to use
+different areas of the screen for different purposes: text, menus, buttons, etc.
+For this reason, \CONTEXT\ provides not only left and right margins, but also
+additional left and right edge areas and top and bottom margins. These areas are
+shown in the figure on the next page.

+\stoppostponing
+
+When defining this graphic, all areas have related dimensions. Here it makes
+sense to let \METAPOST\ calculate these dimensions as much as possible. First we
+define the five by five matrix of areas. We pass the width and height of the main
+text area. Because they are stored in \TEX\ dimension registers, we have to
+prefix them by \type {\the}.
+
+\typebuffer[aa]
+
+We now specify the lower left corners using \type {=} instead of the \type {:=},
+which means that \METAPOST\ will calculate \type {w[3]} and \type {h[3]} for us.
+
+\typebuffer[bb]
+
+Because we are going to repeat ourselves, we draw the areas using a macro.
+Depending on its importance, we color it red or yellow.
+
+\typebuffer[cc]
+
+This picture in itself is not yet explanatory, so we add some labels. Again, we
+use a macro, which we feed with a picture generated by \TEX. Since these pictures
+are filtered from the source and pre||processed, we cannot embed the \type
+{btex}||\type {etex} in the macro \type {do_it} and pass a string. It has to be
+done this way. \footnote {This is true only in a regular \METAPOST\ run. In
+\CONTEXT\ \MKIV\ we follow a different route.}
+
+\typebuffer[dd]
+
+In the horizontal direction we have edges, margins and text. There are left and
+right edges and margins, which are swapped on even pages when you typeset a
+double sided document.
+
+\typebuffer[ee]
+
+Since we want the graphic to match the dimensions of the text area of the current
+page, we have to make sure that the bounding box is adapted accordingly. By this
+action, the labels will fall outside the bounding box. When we directly embed a
+graphic, this works ok, but when we start scaling and reusing, due to the object
+reuse mechanism the graphic will be clipped to the bounding box.
+
+\typebuffer[ff]
+
+In the following sections we will demonstrate how you can put graphics behind
+these 25~areas, as well as behind the (left and right) page.
+
+\stopsection
+
+\startsection[title={Setting up backgrounds}]
+
+\index {overlays}
+\index {backgrounds}
+
+One way of protecting a document for unwanted usage is to put an annoying word in
+the background. If you like this, you may try the following. The macro \type
+{ysized} is part of the macros that come with \CONTEXT\ and scales a picture to a
+specific size.
+
+\startbuffer[a]
+\startuniqueMPgraphic{concept}
+  draw btex \colored[s=.8]{\bf CONCEPT} etex rotated 60 ;
+  currentpicture := currentpicture
+    ysized (\overlayheight-.5cm) ;
+\stopuniqueMPgraphic
+
+\defineoverlay[concept][\uniqueMPgraphic{concept}]
+\stopbuffer
+
+\typebuffer[a]
+
+You can now put this graphic in the page background by
+saying:
+
+\starttyping
+\setupbackgrounds[page][background=concept]
+\stoptyping
+
+You may consider the next alternative a bit better, but still it renders the text
+unreadable. Like \type {xysized}, the macro \type {enlarged} is not part of
+standard \METAPOST, but comes with \CONTEXT.
+
+\startbuffer[b]
+\startuniqueMPgraphic{copyright}
+  picture p ; p := btex \colored[s=.8]{COPYRIGHT} etex
+    rotated 90 ;
+  setbounds p to boundingbox p enlarged 1pt ;
+  draw p ;
+  currentpicture := currentpicture
+    xysized (\overlaywidth,\overlayheight) ;
+\stopuniqueMPgraphic
+
+\defineoverlay[copyright][\uniqueMPgraphic{copyright}]
+\stopbuffer
+
+\typebuffer[b]
+
+Again, we put this graphic in the background. By using a unique graphic, we make
+sure that it's rendered only once and reused when possible.
+
+\startbuffer[c]
+\setupbackgrounds[text][rightmargin][background=copyright]
+\stopbuffer
+
+\typebuffer[c]
+
+\doifnotmode{screen}{\getbuffer[b,c]}
+
+In both cases, we slightly scale down the graphic. We do so because otherwise a
+small portion of the text is clipped off. This is unrelated to \TEX\ or
+\METAPOST, but a characteristic of the font. Compare the following Pagella, Latin
+Modern and Termes gi's (the Pagella is the body font of this text).
+
+\startbuffer
+\hbox \bgroup
+    \hbox{\definedfont[file:texgyrepagella-regular at 6cm]gi}%
+    \hbox{\definedfont[file:lmroman10-regular      at 6cm]gi}%
+    \hbox{\definedfont[file:texgyretermes-regular  at 6cm]gi}%
+\egroup
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+{\showboxes \getbuffer}
+\stoplinecorrection
+
+Watch how the bounding boxes differ and sometimes cross the shape. So, in order
+not to loose part of a glyph when clipping, you need to add a bit of space. \in
+{Figure} [fig:annoying] shows the two backgrounds in action.
+
+\startbuffer
+\getbuffer[a,b]
+\def\ShowPage#1% % (yet) no image as background to image
+  {\framed       % possible due to nested file problems

+
+\placefigure
+  [here][fig:annoying]
+  {Two examples of annoying backgrounds.}
+  {\getbuffer}
+
+If you really want to add such texts to a document, in \CONTEXT\ we don't have to
+use the page background, but can use one of the layout areas instead (like \type
+{[text][text]} or \type {[text][leftmargin]})
+
+\typebuffer[d]
+
+There is one drawback: when your left and right margin have different dimensions,
+the text will be scaled differently on odd and even pages. Normally this is no
+problem for a draft.
+
+As an alternative you can use the \type {\setuptexts} command and wrap the
+graphic in a box with the right dimensions, using code like:
+
+\starttyping
+\startuniqueMPgraphic{copyright}
+  picture p ; p := btex COPYRIGHT etex rotated 90 ;
+  setbounds p to boundingbox p enlarged 1pt ;
+  draw p withcolor .8white ;
+  xyscale_currentpicture(\the\leftmarginwidth,\the\textheight) ;
+\stopuniqueMPgraphic
+
+\setuptexttexts [margin] [] [\uniqueMPgraphic{copyright}]
+\stoptyping
+
+The graphic goes into the outer margin. The second argument can be used to put
+something in the inner margin.
+
+\stopsection
+
+\startsection[title={Multiple overlays}]
+
+\index{overlays+stack}
+
+\setupbackgrounds[text][rightmargin][background=]
+
+You can stack overlays. Consider the next case, where we assume that you have
+enabled interaction support using \type {\setupinteraction[state=start]}:
+
+\starttyping
+\setupbackgrounds
+  [page]
+  [background={color,nextpage},
+   backgroundcolor=darkyellow]
+\stoptyping
+
+Here, the page gets a colored background and a hyperlink to the next page,
+previously defined by:
+
+\starttyping
+\defineoverlay[nextpage][\overlaybutton{nextpage}]
+\stoptyping
+
+An \type {\overlaybutton} is just a button, with all attributes (color, frame,
+etc) set to nothing, having the dimensions of the overlay. The argument is one of
+the permitted destinations, like \type {nextpage}, \type {firstpage}, \type
+{SearchDocument} and alike.
+
+For efficiency reasons, the background areas (like \type {[text][text]}) are
+calculated only when their definition has changed. When a background changes per
+page, we have to recalculate it on each page. In the next example, the macro
+\type {\overlaybutton} generates a different button on each page. But, since we
+don't explicitly set the background at each page, there is no way the background
+drawing mechanism can know that this button has changed. Therefore, we must force
+recalculation with:
+
+\starttyping
+\setupbackgrounds[state=repeat]
+\stoptyping
+
+You can test this concept yourself with the following code. Here we assume that
+you have a file called \type {tufte.tex} on your system, which is the case if you
+have \CONTEXT\ installed. However, you can just as easily use any file having a
+paragraph of two of text.
+
+\starttyping
+\starttext
+\setupinteraction[state=start]
+\setupbackgrounds[state=repeat]
+\defineoverlay[nextpage][\overlaybutton{nextpage}]
+\setupbackgrounds[text][text][background=nextpage]
+\dorecurse{20}{\input tufte \par}
+\stoptext
+\stoptyping
+
+Note that you can move forward from page to page in the resulting \PDF\ file by
+clicking on each page with the mouse. Now compile this file without setting the
+background state to \type {repeat} and note the difference as you click pages
+with the mouse.
+
+Setting the state was not needed when we used the page background:
+
+\starttyping
+\setupbackgrounds[page][background=nextpage]
+\stoptyping
+
+The \type {\dorecurse} macro is handy for testing since it saves us typing. One
+can nest this macro as in:
+
+\starttyping
+\dorecurse{20}{\dorecurse{10}{Hello World! }\par}
+\stoptyping
+
+The current step is available in \type {\recurselevel} and the depth (nesting
+level) in \type {\recursedepth}.
+
+\stopsection
+
+\startsection[title={Crossing borders}]
+
+\index{backgrounds}
+
+In many cases, the previously mentioned background areas will suffice, but in the
+case of more complicated backgrounds, you may wish to use \METAPOST\ to draw
+graphics that combine or span these areas.
+
+At runtime \CONTEXT\ saves information on the layout that can be picked up by
+\METAPOST. The framework for a page graphic is:
+
+\starttyping
+StartPage;
+  % all kind of commands
+StopPage ;
+\stoptyping
+
+Between the \type {StartPage} and \type {StopPage} command you have access to a
+wide range of variables:
+
+\starttabulate[|l|Tp|]
+\HL

+The area itself is available as \type {Area}.
+
+\starttyping
+StartPage ;
+  fill Area[Text][Text] withcolor .85white ;
+StopPage ;
+\stoptyping
+
+If you use an area this way, you will notice that it is not positioned at the
+right place. An \type {Area} is just a rectangle. If you want a positioned area,
+you should use the \type {Field} array:
+
+\starttyping
+StartPage ;
+  fill Field[Text][Text] withcolor .85white ;
+StopPage ;
+\stoptyping
+
+The location of an area is available in \type {Location}, so the previous
+definition is the same as:
+
+\starttyping
+StartPage ;
+  fill Area[Text][Text] shifted Location[Text][Text]
+    withcolor .85white ;
+StopPage ;
+\stoptyping
+
+The following definition fills and draws the margin and text areas.
+
+\typebuffer[back-2]
+
+This background is assigned to the page layer by saying:
+
+\typebuffer[back-0]
+
+As you can see in \in {figure} [fig:back 2], the text is typeset rather tightly
+between the left and right margins.
+
+\placefigure
+  [here][fig:back 2]
+  {A background with split areas.}
+  {\startcombination
+     {\typesetfile[mfun-900.tex][page=4,width=.4\textwidth]}{even}
+     {\typesetfile[mfun-900.tex][page=5,width=.4\textwidth]}{odd}
+   \stopcombination}
+
+This can easily be solved by enlarging the areas a bit. The next example
+demonstrates this on the text area, which is shown in \in {figure} [fig:back 3].
+
+\typebuffer[back-3]
+
+\placefigure
+  [here][fig:back 3]
+  {A background with enlarged text area.}
+  {\startcombination
+     {\typesetfile[mfun-900.tex][page=6,width=.4\textwidth]}{even}
+     {\typesetfile[mfun-900.tex][page=7,width=.4\textwidth]}{odd}
+   \stopcombination}
+
+The \type {enlarged} macro can be used like \type {shifted} and accepts either a
+numeric or a pair.
+
+How do we define a background as in \in {figure} [fig:back 1]? Because \type
+{Field} provides us the positioned areas, we can use the corners of those.
+
+\typebuffer[back-1]
+
+In this definition we calculate a different path for odd and even pages. When
+done, we enlarge the path a bit. If you want to use different offsets in all
+directions, you can use moved corner points.
+
+\typebuffer[back-4]
+
+Here we displace the corners randomly which leads to backgrounds like \in
+{figure} [fig:back 4]. The following definition would have worked as well:
+
+\typebuffer[back-4x]
+
+\placefigure
+  [here][fig:back 4]
+  {A random text area.}
+  {\startcombination
+     {\typesetfile[mfun-900.tex][page=8,width=.4\textwidth]}{even}
+     {\typesetfile[mfun-900.tex][page=9,width=.4\textwidth]}{odd}
+   \stopcombination}
+
+The previous graphics are defined as usable ones, which means that they will be
+recalculated each page. This is rather inefficient when the shapes don't change.
+But, using a reusable graphic instead, would result in only one graphic for both
+pages. Since the layout for the left and right page differs, another method is
+needed.
+
+Instead of putting the same graphic on the page layer, we put two different ones
+on the left and right page layer.
+
+\starttyping
+\defineoverlay[left page] [\useMPgraphic{left page}]
+\defineoverlay[right page][\useMPgraphic{right page}]
+
+\setupbackgrounds[leftpage] [background=left page]
+\setupbackgrounds[rightpage][background=right page]
+\stoptyping
+
+Now we only have to split the previously defined graphic into two parts. In order
+to force consistency, we isolate the code that fills and draws. The left page
+code looks like:
+
+\starttyping
+\startreusableMPgraphic{left page}
+  StartPage ;
+    path Main ; Main :=
+      llcorner Field[OuterMargin][Text] --
+      lrcorner Field[Text]       [Text] --
+      urcorner Field[Text]       [Text] --
+      ulcorner Field[OuterMargin][Text] -- cycle ;
+    \includeMPgraphic{draw page}
+  StopPage ;
+\stopreusableMPgraphic
+\stoptyping
+
+The right page text looks similar:
+
+\starttyping
+\startreusableMPgraphic{right page}
+  StartPage ;
+    path Main ; Main :=
+      lrcorner Field[OuterMargin][Text] --
+      llcorner Field[Text]       [Text] --
+      ulcorner Field[Text]       [Text] --
+      urcorner Field[OuterMargin][Text] -- cycle ;
+    \includeMPgraphic{draw page}
+  StopPage ;
+\stopreusableMPgraphic
+\stoptyping
+
+Watch how we used a reusable graphic first and a simple usable one next.
+Actually, the next graphic is not a stand alone graphic.
+
+\starttyping
+\startuseMPgraphic{draw page}
+  Main := Main enlarged 6pt ;
+  pickup pencircle scaled 2pt ;
+  fill Page withcolor .625white ;

+
+We have seen some predefined paths and locations. Apart from the \type {Page}
+path, they take two arguments that specify their position on the layout grid.

+The array variables are accessed by using constants:

+
+In addition to these, there are \type {Margin}, \type {InnerMargin} and \type
+{OuterMargin} which adapt themselves to the current odd or even page. The same is
+true for \type {Edge}, \type {InnerEdge} and \type {OuterEdge}, although these
+will seldom be used, since interactive documents are always single sided.
+
+We started this chapter with spending a lot of code to simulate the page areas.
+It will be clear now that in practice this is much easier using the mechanism
+described here.

+
+In \in {figure} [fig:back 5] we see all used areas. Areas that are not used are
+not drawn (which saves some testing). This background was defined as:
+
+\typebuffer[back-5]
+
+We use two nested \type {for} loops to step over the areas. A \type {for} loop
+with a step of~1 will fail, because the indices are defined in a rather special
+way. On the other hand, the mechanism is rather tolerant, in the sense that \type
+{[i][j]} and \type {[j][i]} are both accepted.

+If you want to share your document all over the world, it makes sense to use a
+paper format like {\em letter} or {\em A4}. In that case, the layout often
+matches the paper size.

+The left picture demonstrates what happens when you have a printer that is
+capable of printing from edge to edge. If you have such a printer, you're lucky.
+The middle picture demonstrates what happens if you have a properly set up
+printing program and|/|or printer: the page is scaled down so that the content
+fits into the non printable area of the printer. One reason why printers don't
+print from edge to edge is that the engine is not that happy when toner or ink
+ends up next to the page. The third picture shows what happens when a printer
+simply ignores content that runs over the non printable area. In many cases it's
+best to make sure that the content leaves a margin of 5mm from the edges.
+
+Books and magazines seldom use the popular desk||top paper sizes. Here the
+designer determined the paper size and layout more or less independent from the
+size of the sheet on which the result is printed. Instead of one page per sheet,
+arrangements of 2 upto 32 or more pages per sheet are made. The process of
+arranging pages in such a way that these sheets can be folded and combined into
+books is called page imposition. \CONTEXT\ supports a wide range of page
+imposition schemes. More information on this can be found in the \CONTEXT\
+manuals.
+
+The fact that the sheet on which a page is printed is larger than the page itself
+opens the possibility to use the full page for content. In that case, especially
+when you use background graphics, you need to make sure that indeed the page is
+covered completely. Where in desk top printing you can get away with imperfection
+simply because the printing engines have their limitations, in professional
+output you need to be more considerate.

+Slightly enlarging a graphic so that it exceeds the natural page limits is called
+bleeding. Because quite often layout elements have a rectangular nature,
+\METAFUN\ provides a couple of operations that can save you some work in defining
+bleeding boxes.

+
+This graphic is generated as follows:
+
+\typebuffer
+
+The trick is in the last couple of lines. In addition to the general \type
+{enlarged} operator, we have 4~operators that enlarge a rectangle in a certain
+direction. This means that we can define the original path using dimensions
+related to the layout, and add bleed strips independently.
+
+\startbuffer
+path p ; p := fullsquare xyscaled (4cm,1cm) ;
+path q ; q := p leftenlarged 2mm topenlarged 2mm ;

+
+This example demonstrates that when we enlarge a graphic, the bounding box also
+gets larger. Because this can interfere with the placement of such a graphic, we
+need to make sure that the bleeding is there but not seen.

+\startchapter[title={A few more details}]
+
+\startintro
+
+In this chapter we will see how to define a \METAPOST\ graphic, and how to
+include it in a document. Since the exact dimensions of graphics play an
+important role in the placement of a graphic, we will explore the way a bounding
+box is constructed.
+
+We will also pay attention to the usage of units and the side effects of scaling
+and shifting, since they can contradict our expectations in unexpected ways.
+Furthermore we will explore a few obscure areas.
+
+\stopintro
+
+\startsection[title={Making graphics}]
+
+\index{graphics}
+
+In this manual we will use \METAPOST\ in a rather straightforward way, and we
+will try to avoid complicated math as much as possible. We will do a bit of
+drawing, clipping, and moving around. Occasionally we will see some more
+complicated manipulations.
+
+When defined as stand||alone graphic, a \METAPOST\ file looks like this:
+
+\starttyping
+% Let's draw a circle.
+
+beginfig (7) ;
+  draw fullcircle scaled 3cm withpen pencircle scaled 1cm ;
+endfig ;
+
+end .
+\stoptyping
+
+The main structuring components in such a file are the \type {beginfig} and \type
+{endfig} macros. Like in a big story, the file has many sub||sentences, where
+each sub||sentence ends with a semi||colon. Although the \type {end} command at
+the end of the file concludes the story, putting a period there is a finishing
+touch. Actually, after the \type {end} command you can put whatever text you
+wish, your comments, your grocery list, whatever. Comments in \METAPOST, prefixed
+by a percent sign, as in \typ {% Let's draw a circle}, are ignored by the
+interpreter, but useful reminders for the programmer.
+
+If the file is saved as \type {yourfile.mp}, then the file is processed by
+\METAPOST\ by issuing the following command:
+
+\starttyping
+mpost yourfile
+\stoptyping
+
+after which you will have a graphic called \type {yourfile.7}, which contains a
+series of \POSTSCRIPT\ commands. Because \METAPOST\ does all the work, this file
+is efficient and compact. The number of distinct \POSTSCRIPT\ operators used is
+limited, which has the advantage that we can postprocess this file rather easily.
+Alternatively \METAPOST\ can generate \SVG\ output. It does when you say
+
+\starttyping
+outputformat := "svg" ;
+\stoptyping
+
+Here we will not go into details about this format. Even \POSTSCRIPT\ is not
+covered in detail as we use \METAPOST\ mostly in embedded form.
+
+We can view this file in a \POSTSCRIPT\ viewer like \GHOSTVIEW\ or convert the
+graphic to \PDF\ (using \type {mptopdf}) and view the result in a suitable \PDF\
+viewer like \ACROBAT. Of course, you can embed such a file in a \CONTEXT\
+document, using a command like:
+
+\starttyping
+\externalfigure[yourfile.7]
+\stoptyping
+
+We will go in more detail about embedding graphics in \in {chapter}
+[sec:embedding].
+
+If you have installed \CONTEXT, somewhere on your system there resides a file
+\type {mp-tool.mp}. If you make a stand||alone graphic, it's best to put the
+following line at the top of your file:
+
+\starttyping
+input mp-tool ; % or input metafun ;
+\stoptyping
+
+By loading this file, the resulting graphic will provide a high resolution
+bounding box, which enables more accurate placement. The file also sets the \typ
+{prologues := 1} so that viewers like \GHOSTVIEW\ can refresh the file when it is
+changed.
+
+Next we will introduce some more \METAPOST\ commands. From now on, we will omit
+the encapsulating \type {beginfig} and \type {endfig} macros. If you want to
+process these examples yourself, you should add those commands yourself, or if
+you use \CONTEXT\ you don't need them at all.
+
+\startbuffer
+pickup pencircle scaled .5cm ;
+draw unitsquare xscaled 8cm yscaled 1cm withcolor .625white ;
+draw origin withcolor .625yellow ;
+pickup pencircle scaled 1pt ;
+draw bbox currentpicture withcolor .625red ;
+\stopbuffer
+
+\typebuffer
+
+In this example we see a mixture of so called primitives as well as macros. A
+primitive is something hard coded, a built||in command, while a macro is a
+collection of such primitives, packaged in a way that they can be recalled
+easily. Where \type {scaled} is a primitive and \type {draw} a macro, \type
+{unitsquare} is a path variable, an abbreviation for:
+
+\starttyping
+unitsquare = (0,0) -- (1,0) -- (1,1) -- (0,1) -- cycle ;
+\stoptyping
+
+The double dash (\type {--}) is also a macro, used to connect two points with a
+straight line segment. However, \type {cycle} is a primitive, which connects the
+last point of the unitsquare to the first on unitsquare's path. Path variables
+must first be declared, as in:
+
+\starttyping
+path unitsquare ;
+\stoptyping
+
+A large collection of such macros is available when you launch \METAPOST. Consult
+the \METAPOST\ manual for details.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+In the first line of our example, we set the drawing pen to \type {.5cm}. You can
+also specify such a dimension in other units, like points (\type {pt}). When no
+unit is provided, \METAPOST\ will use a big point (\type {bp}) , the \POSTSCRIPT\
+approximation of a point.
+
+The second line does just as it says: it draws a rectangle of certain dimensions
+in a certain color. In the third line we draw a colored dot at the origin of the
+coordinate system in which we are drawing. Finally, we set up a smaller pen and
+draw the bounding box of the current picture, using the variable \type
+{currentpicture}. Normally, all drawn shapes end up in this picture variable.
+
+\stopsection
+
+\startsection[title={Bounding boxes}]
+
+\index{boundingbox}
+
+If you take a close look at the last picture in the previous section, you will
+notice that the bounding box is larger than the picture. This is one of the nasty
+side effects of \METAPOST's \type {bbox} macro. This macro draws a box, but with
+a certain offset. The next example shows how we can manipulate this offset.
+Personally I never use the \type {bbox} macro because this offset is rather
+annoying. Also, the \type {boundingbox} operator combined with \type {enlarged}
+can provide any offset you want.
+
+\startbuffer
+pickup pencircle scaled .5cm ;
+draw unitsquare xscaled 8cm yscaled 1cm withcolor .625white ;
+path bb ; bboxmargin := 0pt ; bb := bbox currentpicture ;
+draw bb withpen pencircle scaled 1pt withcolor .625red ;
+draw origin withpen pencircle scaled 5pt withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer
+
+In the third line we define a path variable. We assign the current bounding box
+to this variable, but first we set the offset to zero. The last line demonstrates
+how to draw such a path. Instead of setting the pen as we did in the first line,
+we pass the dimensions directly.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Where \type {draw} draws a path, the \type {fill} macro fills one. In order to be
+filled, a path should be closed, which is accomplished by the \type {cycle}
+primitive, as we saw in constructing the \type {unitsquare} path.
+
+\startbuffer
+pickup pencircle scaled .5cm ;
+fill unitsquare xscaled 8cm yscaled 1cm withcolor .625white ;
+path bb ; bboxmargin := 0pt ; bb := bbox currentpicture ;
+draw bb withpen pencircle scaled 1pt withcolor .625red ;
+draw origin withpen pencircle scaled 5pt withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer
+
+This example demonstrates that when we fill the path, the resulting graphic is
+smaller. Where \type {draw} follows the center of a path, \type {fill} stays
+inside the path.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+A third alternative is the \type {filldraw} macro. From the previous examples, we
+would expect a bounding box that matches the one of the drawn path.
+
+\startbuffer
+pickup pencircle scaled .5cm ;
+filldraw unitsquare xscaled 8cm yscaled 1cm withcolor .625white ;
+path bb ; bboxmargin := 0pt ; bb := bbox currentpicture ;
+draw bb withpen pencircle scaled 1pt withcolor .625red ;
+draw origin withpen pencircle scaled 5pt withcolor .625yellow ;

+% The resulting graphic has the bounding box of the fill. Note
+% how the path, because it is stroked with a .5cm pen, extends
+% beyond the border of the bounding box. The way this image
+% shows up depends on the viewer (settings) you use to render
+% the graphic. For example, in \GHOSTVIEW, if you disable
+% clipping to the bounding box, only the positive quadrant of
+% the graphic is shown. Further, if you enable clipping to the
+% bounding box, this image will look exactly like the previous
+% image created with the fill command. In many cases, it may
+% be best to avoid the \type {filldraw} command.

+results in a proper bounding box:

+
+The \CONTEXT\ distribution comes with a set of \METAPOST\ modules, one of which
+contains the \type {drawfill} macro, which provides the outer bounding box.
+\footnote {Starting from version 1.0 \METAPOST\ calculates the boundingbox
+differently and the distinction between \type {drawfill} and \type {filldraw} is
+gone. We keep them around both for compatibility.} Next we demonstrate its use in
+another, more complicated example.
+
+\startbuffer
+picture finalpicture ; finalpicture := nullpicture ;
+numeric n ; n := 0 ; bboxmargin := 0pt ;
+pickup pencircle scaled .5cm ;
+
+def shape =
+  unitsquare scaled 2cm withcolor .625white ;
+  draw bbox currentpicture

+  currentpicture := nullpicture ; n := n+1 ;

+
+fill shape ; draw shape ; filldraw shape ; drawfill shape ;
+
+currentpicture := finalpicture ;
+\stopbuffer
+
+\typebuffer
+
+Here we introduce a macro definition, \type {shape}. In \METAPOST, the start of a
+macro definition is indicated with the keyword \type {def}. Thereafter, you can
+insert other variables and commands, even other macro definitions. The keyword
+\type {enddef} signals the end of the macro definition. The result is shown in
+\in {figure} [fig:draws and fills]; watch the bounding boxes. Close reading of
+the macro will reveal that the \type {fill}, \type {draw}, \type {filldraw} and
+\type {drawfill} macros are applied to the first \type {unitsquare} path in the
+macro.
+
+\placefigure
+  [here]
+  [fig:draws and fills]
+  {A \type {fill}, \type {draw}, \type {filldraw} and \type
+   {drawfill} applied to the same square.}
+  {\processMPbuffer}
+
+In this macro, \type {bbox} calls a macro that returns the enlarged bounding box
+of a path. By setting \type {bboxmargin} we can influence how much the bounding
+box is enlarged. Since this is an existing variable, we don't have to allocate
+it, like we do with~\type{numeric n}. Unless you take special precautions,
+variables are global by nature and persistent outside macros.
+
+\starttyping
+picture finalpicture ; finalpicture := nullpicture ;
+\stoptyping
+
+Just as \type {numeric} allocates an integer variable, the \type {picture}
+primitive allocates a picture data structure. We explicitly have to set this
+picture to nothing using the built||in primitive \type {nullpicture}.
+
+Later on, we will add the drawn paths as accumulated in \type {currentpicture} to
+this \type {finalpicture} in the following manner.
+
+\starttyping
+addto finalpicture also currentpicture shifted(n*3cm,0) ;
+\stoptyping
+
+Since we want to add a few more and don't want them to overlap, we shift them.
+Therefore we have to erase the current picture as well as increment the shift
+counter.
+
+\starttyping
+currentpicture := nullpicture ; n := n+1 ;
+\stoptyping
+
+The \type {drawfill} macro is one of the \METAFUN\ macros. Another handy macro is
+\type {boundingbox}. When used instead of \type {bbox}, you don't have to set the
+margin to zero.

+  [fig:more draws and fills]
+  {The influence of pens on \type {fill}.}
+  {\processMPbuffer}
+
+There is a subtle point in filling a shape. In \in {figure} [fig:more draws and
+fills] you see the influence of the pen on a \type {fill} operation. An indirect
+specification has no influence, and results in a filled rectangle with sharp
+corners. The third rectangle is drawn with a direct pen specification which
+results in a larger shape with rounds corners. However, the bounding box is the
+same in all three cases. The graphic is defined as follows. This time we don't
+use a (complicated) macro.
+
+\typebuffer
+
+When a graphic is constructed, its components end up in an internal data
+structure in a more or less layered way. This means that as long as a graphic is
+not flushed, you may consider it to be a stack of paths and texts with the paths
+being drawn or filled shapes or acting as clipping paths or bounding boxes.
+
+When you ask for the dimensions of a graphic the lower left and upper right
+corner are calculated using this stack. Because you can explicitly set bounding
+boxes, you can lie about the dimensions of a graphic. This is a very useful
+feature. In the rare case that you want to know the truth and nothing but the
+truth, you can tweak the \type {truecorners} numeric variable. We will
+demonstrate this with a few examples.

+\index{units}
+
+Like \TEX, \METAPOST\ supports multiple units of length. In \TEX, these units are
+hard coded and handled by the parser, where the internal unit of length is the
+scaled point (\type {sp}), something on the nanometer range. Because \METAPOST\
+is focused on \POSTSCRIPT\ output, its internal unit is the big point (\type
+{bp}). All other units are derived from this unit and available as numeric
+instead of hard coded.

+cm = 28.34645 ; pc = 11.95517 ; cc = 12.79213 ; in := 72 ;
+\stoptyping
+
+Careful reading reveals that only the \type {bp} and \type {in} are fixed, while
+the rest of the dimensions are scalar multiples of \type {bp}.
+
+Since we are dealing with graphics, the most commonly used dimensions are \type
+{pt}, \type {bp}, \type {mm}, \type {cm} and~\type {in}.

+
+In \METAPOST\ the following lines are identical:
+
+\starttyping
+draw fullcircle scaled 100 ;
+draw fullcircle scaled 100bp ;
+\stoptyping
+
+You might be tempted to omit the unit, but this can be confusing, particularly if
+you also program in a language like \METAFONT, where the \type {pt} is the base
+unit. This means that a circle scaled to 100 in \METAPOST\ is not the same as a
+circle scaled to 100 in \METAFONT. Consider the next definition:
+
+\startbuffer
+pickup pencircle scaled 0 ;
+fill unitsquare
+  xscaled 400pt yscaled -.5cm withcolor .625red ;
+fill unitsquare
+  xscaled 400bp yscaled +.5cm withcolor .625yellow ;
+drawoptions(withcolor white) ;
+label.rt("400 pt", origin shifted (0, -.25cm)) ;
+label.rt("400 bp", origin shifted (0, +.25cm)) ;
+\stopbuffer
+
+\typebuffer
+
+When processed, the difference between a \type {pt} and \type {bp} shows rather
+well. Watch how we use \type {.rt} to move the label to the right; you can
+compare this with \TEX's macro \type {\rlap}. You might want to experiment with
+\type {.lft}, \type {.top}, \type {.bot}, \type {.ulft}, \type {.urt}, \type
+{.llft} and \type {.lrt}.
+
+The difference between both bars is exactly \scratchdimen = 400 bp
+\advance\scratchdimen by -400 pt \the \scratchdimen \space (as calculated by
+\TEX).
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Where \TEX\ is anchored in tradition, and therefore more or less uses the \type
+{pt} as the default unit, \METAPOST, much like \POSTSCRIPT, has its roots in the
+computer sciences. There, to simplify calculations, an inch is divided in 72 big
+points, and .72pt is sacrificed.
+
+When you consider that \POSTSCRIPT\ is a high end graphic programming language,
+you may wonder why this sacrifice was made. Although the difference between \type
+{1bp} and \type {1pt} is miniscule, this difference is the source of much
+(unknown) confusion. When \TEX\ users talk about a \type {10pt} font, a desktop
+publisher hears \type {10bp}. In a similar vein, when we define a papersize
+having a width of \type {600pt} and a height of \type {450pt}, which is papersize
+\type {S6} in \CONTEXT, a \POSTSCRIPT\ or \PDF\ viewer will report slightly
+smaller values as page dimensions. This is because those programs claim the \type
+{pt} to be a \type {bp}. [This confusion can lead to interesting discussions with
+desktop publishers when they have to use \TEX. They often think that their demand
+of a baseline distance of \type {13.4} is met when we set it to \type {13.4pt},
+while actually they were thinking of \type {13.4bp}, which of course in other
+programs is specified using a \type {pt} suffix.]
+
+Therefore, when embedding graphics in \CONTEXT, we strongly recommend that you
+use \type {pt} as the base unit instead. The main reason why we spend so many
+words on this issue is that, when neglected, large graphics may look inaccurate.
+Actually, when taken care of, it is one of the (many) reasons why \TEX\ documents
+always look so accurate. Given that the eye is sensitive to distortions of far
+less than \type {1pt}, you can be puzzled by the fact that many drawing programs
+only provide a bounding box in rounded units. Thereby, they round to the next
+position, to prevent unwanted cropping. For some reason this low resolution has
+made it into the high end \POSTSCRIPT\ standard.
+
+In \CONTEXT\ we try to deal with these issues as well as possible.

+When we draw a shape, \METAPOST\ will adapt the bounding box accordingly. This
+means that a graphic has its natural dimensions, unless of course we adapt the

+rectangle, shifting it to some place can get obscured by this fact. Therefore,
+the following series of shapes appear to be the same.

+Chapter 3 of the \METAFONT\ book explains the mathematics behind the construction
+of curves. Both \METAFONT\ and \METAPOST\ implement B\'ezier curves. The fact
+that these curves are named after Pierre B\'ezier obscures the fact that the math
+behind them originates with Serge\u{\i} Bernshte\u{\i}n.
+
+The points on the curve are determined by the following formula:
+
+\placeformula[-]
+\startformula
+z(t) = (1-t)^3 z_1 + 3 (1-t)^2 t z_2 + 3 (1-t) t^2 z_3 + t^3 z_4
+\stopformula
+
+Here, the parameter $t$ runs from $[0,1]$. As you can see, we are dealing with
+four points. In practice this means that when we construct a curve from multiple
+points, we act on two points and the two control points in between. So, the
+segment that goes from $z_1$ to $z_4$ is calculated using these two points and
+the points that \METAFONT|/|\METAPOST\ calls post control point and pre control
+point.

+The previous curve is constructed from the three points $z_1$, $z_4$ and $z_7$.
+The curve is drawn in \METAPOST\ by \type {z1..z4..z7} and is made up out of two
+segments. The first segment is determined by the following points:
+
+\startitemize[packed,n]
+\item point $z_1$ of the curve
+\item the postcontrol point $z_2$ of $z_1$
+\item the precontrol point $z_3$ of $z_4$
+\item point $z_4$ of the curve
+\stopitemize
+
+On the next pages we will see how the whole curve is constructed from these
+quadruples of points. The process comes down to connecting the mid points of the
+straight lines to the points mentioned. We do this three times, which is why
+these curves are classified as third order approximations.

+The first series of graphics demonstrates the process of determining the mid
+points. The third order midpoint is positioned on the final curve. The second
+series focuses on the results: new sets of four points that will be used in a
+next stage. The last series only shows the third order midpoints. As you can see,
+after some six iterations we have already reached a rather good fit of the final
+curve. The exact number of iterations depends on the resolution needed. You will
+notice that the construction speed (density) differs per segment.

+We need to loop over all segments of a curve, where for each segment the left and
+right side sub curves are handled recursively, upto the requested depth (denoted
+as \type {n}). For this we define the following macros.

+
+\startbuffer[zero]
+drawoptions (withpen pencircle scaled 5pt withcolor .625red);
+\stopbuffer
+
+\startbuffer[extra]
+drawoptions (withpen pencircle scaled 5pt withcolor .625yellow);

+
+We apply this macro to a simple shape:
+
+\startbuffer[one]
+drawmidpoints (fullcircle xscaled 300pt yscaled 50pt, 1) ;
+\stopbuffer
+
+\typebuffer[one]
+
+When drawn, this results in the points that makes up the

+We now add an extra iteration (resulting in the yellow points):

+\startbuffer[two]
+drawmidpoints (fullcircle xscaled 300pt yscaled 50pt, 2) ;
+\stopbuffer
+
+\typebuffer[two]
+
+and get:

+\startlinecorrection[blank]
+\processMPbuffer[demo,zero,two,extra,one]
+\stoplinecorrection
+
+We don't even need that much iterations to get a good result. The depth needed to
+get a good result depends on the size of the pen and the resolution of the device
+on which the curve is visualized.

+\startsection[title={Inflection, tension and curl}]
+
+\index{inflection}
+\index{tension}
+\index{curl}
+
+The \METAPOST\ manual describes the meaning of \type {...} as \quotation {choose
+an inflection||free path between these points unless the endpoint directions make
+this impossible}. To use the words of David Arnold: a point of inflection is
+where a path switches concavity, from concave up to concave down, for example.
+
+It is surprisingly difficult to find nice examples that demonstrate the
+difference between \type {..} and \type {...}, as it is often \quote {impossible}
+to honour the request for less inflection. We will demonstrate this with a few
+graphics.
+
+In the four figures on the next pages, you will see that \type {...} is not
+really suited for taming wild curves. If you really want to make sure that a
+curve stays within certain bounds, you have to specify it as such using control
+or intermediate points. In the figures that follow, the gray curves draw the
+random path using \type {..} on top of yellow curves that use the \type {...}
+connection. As you can see, in only a few occasions do the yellow \quote
+{inflection} free curves show up.
+
+For those who asked for the code that produces these pictures, we now include it
+here. We use a macro \type {sample} which we define as a usable graphic (nearly
+all examples in this manual are coded in the document source).
+
+\startbuffer
+\startuseMPgraphic{sample}
+def sample (expr rx, ry) =
+  path p, q ; numeric n, m, r, a, b ;
+  color c ; c := \MPcolor{lightgray} ;
+  a := 3mm ; b := 2mm ; r := 2cm ; n := 7 ; m := 5 ;
+  q := unitsquare scaled r xyscaled (n,m) shifted (.5r,.5r) ;
+  draw q withpen pencircle scaled (b/4) withcolor .625yellow;
+  for i=1 upto n : for j=1 upto m :
+    p := (fullcircle scaled r randomized (r/rx,r/ry))
+      shifted ((i,j) scaled r) ;
+    pickup pencircle scaled a ;
+    draw for k=0 upto length(p) :
+      point k of p ..  endfor cycle withcolor c ;
+    draw for k=0 upto length(p) :

+
+The tension specifier can be used to influence the curvature. To quote the
+\METAPOST\ manual once more: \quotation {The tension parameter can be less than
+one, but it must be at least $3/4$}. The following paths are the same:
+
+\starttyping
+z1 .. z2
+z1 .. tension 1 .. z2
+z1 .. tension 1 and 1 .. z2
+\stoptyping
+
+The triple dot command \type {...} is actually a macro that makes the following
+commands equivalent. Both commands will draw identical paths.
+
+\starttyping
+z1 ... z2
+z1 .. tension atleast 1 .. z2
+\stoptyping
+
+The \type {atleast} directive tells \METAPOST\ to do some magic behind the
+screens. Both the $3/4$ and the \type {atleast} lead directly to the question:
+\quotation {What, exactly, is the influence of the tension directive?} We will
+try to demystify the \type {tension} specifier through a sequence of graphics.
+
+\startbuffer
+u := 1cm ; z1 = (0,0) ; z2 = (2u,4u) ; z3 = (4u,0) ;

+Indeed values less than .75 give an error message, but large values are okay. As
+you can see, the two gray curves are the same. Here, \type {atleast 1} means~1,
+even if larger values are useful.

+Curves finally are made up out of points, and each point has two control points.
+Since the \type {tension} specifier finally becomes a control point, it is not
+surprising that you may specify two tension values. If we replace the tension in
+the previous example by
+
+\starttyping

+
+A third magic directive is \type {curl}. The curl is attached to a point between
+\type {{ }}, like \type {{curl 2}}. Anything between curly braces is a direction
+specifier, so instead of a \type {curl} you may specify a vector, like \type
+{{(2,3)}}, a pair of numbers, as in \type {{2,3}}, or a direction, like \type
+{{dir 30}}. Because vectors and angles are straightforward, we will focus a bit
+on \type {curl}.
+
+\starttyping
+z0 .. z1 .. z2
+z0 {curl 1} .. z1 .. {curl 1} z2
+\stoptyping
+
+So, a \type {curl} of~1 is the default. When set to~1, the begin and|/|or end
+points are approached. Given the following definitions:
+
+\startbuffer[a]
+u := 1cm ; z1 = (0,0) ; z2 = (2u,4u) ; z3 = (4u,0) ;
+def sample (expr p, c) =

+We can draw three curved paths.

+sample (z1 {curl 1} .. z2 .. {curl 1} z3, .625white) ;
+\stopbuffer
+
+\typebuffer[b]
+
+The third (gray) curve is the default situation, so we could have left the \type
+{curl} specifier out of the expression.

+\stoplinecorrection

+sample (z1 {curl        1} .. z2 .. {curl        1} z3, .625white) ;
+\stopbuffer
+
+The curly specs have a lower bound of zero and no upper bound. When we use
+\METAPOST\ maximum value of \type {infinity} instead of~2, we get:
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+These curves were defined as:

+\typebuffer[b]
+
+It may sound strange, but internally \METAPOST\ can handle
+larger values than \type {infinity}.
+
+\startbuffer[b]
+sample (z1 {curl  infinity} .. z2 .. {curl  infinity} z3, .625red) ;
+sample (z1 {curl 4infinity} .. z2 .. {curl 4infinity} z3, .625yellow) ;
+sample (z1 {curl 8infinity} .. z2 .. {curl 8infinity} z3, .625white) ;
+\stopbuffer
+
+\typebuffer[b]
+
+Although this is quite certainly undefined behaviour, interesting effects can be
+achieved. When you turn off \METAPOST's first stage overflow catcher by setting
+\type {warningcheck} to zero, you can go upto 8 times \type {infinity}, which,
+being some $2^{15}$, is still far from what today's infinity is supposed to be.

+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+As the built||in \METAPOST\ command \type {..} accepts the \type {curl} and \type
+{tension} directives as described in this section, you will now probably
+understand the following plain \METAPOST\ definitions:
+
+\starttyping
+def --  = {curl 1} .. {curl 1}    enddef ;
+def --- = .. tension infinity ..  enddef ;
+def ... = .. tension atleast 1 .. enddef ;

+These definitions also point out why you cannot add directives to the left or

+themselves!

+\type {p transform T} is a pair of the form:
+
+\startformula
+(t_x + t_{xx} p_x + t_{xy} p_y, t_y + t_{yx} p_x + t_{yy} p_y)
+\stopformula
+
+where the six numeric quantities $(t_x, t_y, t_{xx}, t_{xy},
+t_{yx}, t_{yy})$ determine T.
+\stopquotation
+
+In literature concerning \POSTSCRIPT\ and \PDF\ you will find many references to
+such transformation matrices. A matrix of $(s_x,0,0,s_y,0,0)$ is scaling by $s_x$
+in the horizontal direction and $s_y$ in the vertical direction, while
+$(1,0,t_x,1,0,t_y)$ is a shift over $t_x,t_y$. Of course combinations are also
+possible.
+
+Although these descriptions seem in conflict with each other in the nature and
+order of the transform components in the vectors, the concepts are the same. You
+normally populate transformation matrices using \type {scaled}, \type {shifted},
+\type {rotated}.
+
+\starttyping
+transform t ; t := identity shifted (a,b) rotated c scaled d ;
+path p ; p := fullcircle transformed t ;
+\stoptyping
+
+The previous lines of code are equivalent to:
+
+\starttyping
+path p ; p := fullcircle shifted (a,b) rotated c scaled d ;
+\stoptyping
+
+You always need a starting point, in this case the identity matrix \type
+{identity}: $(0,0,1,0,0,1)$. By the way, in \POSTSCRIPT\ the zero vector is
+$(1,0,0,1,0,0)$. So, unless you want to extract the components using \type
+{xpart}, \type {xypart}, \type {xxpart}, \type {ypart}, \type {yxpart} and|/|or \
+\type {yypart}, you may as well forget about the internal representation.
+
+You can invert a transformation using the \type {inverse} macro, which is defined
+as follows, using an equation:
+
+\starttyping
+vardef inverse primary T =
+  transform T_ ; T_ transformed T = identity ; T_
+enddef ;
+\stoptyping
+
+Using transform matrices makes sense when similar transformations need to be
+applied on many paths, pictures, pens, or other transforms. However, in most
+cases you will use the predefined commands \type {scaled}, \type {shifted}, \type
+{rotated} and alike. We will now demonstrate the most common transformations in a
+text example.

+\LUATEX\ where we use \MPLIB, so users don't have to worry about these issues:

+\startsection[title={Only this far}]
+
+When you take a close look at the definitions of the Computer Modern Roman fonts,
+defined in the \METAFONT\ book, you will notice a high level of abstraction.
+Instead of hard coded points you will find points defined in terms of \quote
+{being the same as this point} or \quote {touching that point}. In this section
+we will spend some time on this touchy aspect.
+
+\startbuffer[a]
+pickup pencircle scaled 2mm ;
+path p ; p := fullsquare scaled 2cm ;
+draw p withcolor .625white ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+This rectangle is a scaled instance of the predefined \METAFUN\ path \type
+{fullsquare} which is centered around the origin.
+
+\typebuffer[a]
+
+On this path, halfway between two of its corners, we define a point \type {q}:
+
+\startbuffer[b]
+pair q ; q := .5[llcorner p, lrcorner p] ;
+\stopbuffer
+
+\typebuffer[b]
+
+We draw this point in red, using:
+
+\startbuffer[c]
+draw q withcolor .625red ;
+\stopbuffer
+
+\typebuffer[c]
+
+As you can see, this point is drawn on top of the path.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+There are four of those midpoints, and when we connect them, we get:
+
+\startbuffer[c]
+draw q -- q rotated 90 -- q rotated 180 --
+  q rotated 270 -- cycle withcolor .625red ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+Because path \type {p} is centered around the origin, we can simply rotate point
+\type {q} a few times.
+
+\typebuffer[c]
+
+There are situations, where you don't want the red path to be drawn inside
+another path, or more general: where you want points to touch instead of being
+overlayed.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+We can achieve this by defining point \type {q} to be located on top of the
+midpoint.
+
+\startbuffer[b]
+pair q ; q := top .5[llcorner p, lrcorner p] ;
+\stopbuffer
+
+\typebuffer[b]
+
+The predefined macro \type {top} moves the point over the distance similar to the
+current pen width.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+Because we are dealing with two drawing operations, and since the path inside is
+drawn through the center of points, we need to repeat this move in order to draw
+the red path really inside the other one.
+
+\startbuffer[b]
+pair q ; q := top top .5[llcorner p, lrcorner p] ;
+\stopbuffer
+
+\typebuffer[b]
+
+Operations like \type {top} and its relatives \type {bot}, \type {lft} and \type
+{rt} can be applied sequentally.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+We already showed that \type {q} was defined as a series of rotations.
+
+\typebuffer[c]
+
+As an intermezzo we will show an alternative definition of \type {q}. Because
+each point is rotated 90 degrees more, we can define a macro that expands into
+the point and rotates afterwards. Because each consecutive point on the path is
+rotated an additional 90 degrees, we use the \METAPOST\ macro \type {hide} to
+isolate the assignment. The \type {hide} command executes the hidden command and
+afterwards continues as if it were never there. You must not confuse this with
+grouping, since the hidden commands are visible to its surroundings.
+
+\startbuffer[c]
+def qq = q hide(q := q rotated 90) enddef ;
+draw qq -- qq -- qq -- qq -- cycle withcolor .625red ;
+\stopbuffer
+
+\typebuffer[c]
+
+The macro \type {top} uses the characteristics of the current pen to determine
+the displacement. However, for the more complicated pen shapes we need a
+different trick to get an inside path. Let's start by defining an elliptical
+path.
+
+\startbuffer[a]
+pickup pencircle xscaled 3mm yscaled 5mm rotated 30 ;
+path p ; p := fullcircle xscaled 6cm yscaled 3cm ;
+draw p withcolor .625white ;
+\stopbuffer
+
+\typebuffer[a]
+
+We draw this path using a non standard pen. In the \METAFONT\ manual you will
+find methods to draw shapes with similar pens, where the pen is also turning, as
+it does in real calligraphy. Here we stick to a more simple one.
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+We construct the inner path from the points that make up the curve. Watch how we
+use a for loop to compose the new path. When used this way, no semi colon may be
+used to end the loop, since it would isolate the color directive.
+
+\startbuffer[b]
+draw point 0 of p
+  for i=1 upto length(p) : -- point (i) of p endfor
+  withcolor .625red ;
+\stopbuffer
+
+\typebuffer[b]
+
+The points are still located on the original path.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+We can move the points to the inside by shifting them over the penwidth in the
+direction perpendicular to the point. Because we use this transformation more
+than once, we wrap it into a macro. This also keeps the code readable.
+
+\startbuffer[b]
+vardef inside expr pnt of p =
+  (point pnt of p shifted
+     -(penoffset direction pnt of p of currentpen))
+enddef ;
+draw inside 0 of p
+  for i=1 upto length(p) : -- inside i of p endfor
+  withcolor .625red ;
+\stopbuffer
+
+\typebuffer[b]
+
+Whenever you define a pen, \METAPOST\ stores its characteristics in some private
+variables which are used in the \type {top} and alike directives. The \type
+{penoffset} is a built in primitive and is defined as the \quotation {point on
+the pen furthest to the right of the given direction}. Deep down in \METAPOST\
+pens are actually simple paths and therefore \METAPOST\ has a notion of a point
+on the penpath. In the \METAFONT\ book and \METAPOST\ manual you can find in
+depth discussions on pens.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+We're still not there. Like in a previous example, we need to shift over twice
+the pen width. To get good results, we should determine the width of the pen at
+that particular point, which is not trivial. The more general solution, which
+permits us to specify the amount of shifting, is as follows.
+
+\startbuffer[b]
+vardef penpoint expr pnt of p =
+  save n, d ; numeric n, d ;
+  (n,d) = if pair pnt : pnt else : (pnt,1) fi ;
+  (point n of p shifted
+     ((penoffset direction n of p of currentpen) scaled d))
+enddef ;
+\stopbuffer
+
+\typebuffer[b]
+
+When the point specification is extended with a distance, in which case we have a
+pair expression, the point and distance are derived from this specification.
+First we demonstrate the simple case:
+
+\startbuffer[c]
+draw penpoint 0 of p
+  for i=1 upto length(p)-1 : .. penpoint i of p endfor .. cycle
+  withcolor .625red ;
+\stopbuffer
+
+\typebuffer[c]
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+In the next graphic, we draw both an inner and and outer path.
+
+\startbuffer[c]
+draw penpoint (0,-2) of p
+  for i=1 upto length(p)-1 : .. penpoint (i,-2) of p endfor .. cycle
+  withcolor .625red ;
+draw penpoint (0,+2) of p
+  for i=1 upto length(p)-1 : .. penpoint (i,+2) of p endfor .. cycle
+  withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer[c]
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c]
+\stoplinecorrection
+
+\startbuffer[a]
+path p, q, r ;
+
+p := fullcircle scaled 3cm ;
+q := p shifted (7cm,0cm) ;
+r := center p -- center q ;
+\stopbuffer
+
+\startbuffer[b]
+pair pr, qr ;
+
+pr := p intersectionpoint r ;
+qr := q intersectionpoint r ;
+
+r := r cutbefore pr cutafter qr ;
+\stopbuffer
+
+\startbuffer[c]
+r := r cutbefore (point 5pt on r) ;
+r := r cutafter (point -5pt on r) ;
+\stopbuffer
+
+\startbuffer[cc]
+r := r cutends 5pt ;
+\stopbuffer
+
+\startbuffer[d]
+draw p withpen pencircle scaled 10pt withcolor .625red ;
+draw q withpen pencircle scaled 10pt withcolor .625yellow ;
+draw r withpen pencircle scaled 20pt withcolor .625white ;
+\stopbuffer
+
+\startbuffer[dd]
+draw r withpen pencircle scaled 20pt withcolor .625white ;
+draw p withpen pencircle scaled 10pt withcolor .625red ;
+draw q withpen pencircle scaled 10pt withcolor .625yellow ;
+\stopbuffer
+
+Another case when \type {top} and friends cannot be applied in a general way is
+the following. Consider the three paths:
+
+\typebuffer[a]
+
+We draw these paths with:
+
+\typebuffer[d]
+
+The line is drawn from center to center and since the line has a non zero width
+and a round line cap, it extends beyond this point.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,d]
+\stoplinecorrection
+
+If we want the line to stop at the circular paths, we can cut off the pieces that
+extend beyond those paths.
+
+\typebuffer[b]
+
+This time we get:
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,d]
+\stoplinecorrection
+
+Due to the thicker line width used when drawing the straight line, part of that
+line is still visible inside the circles. So, we need to clip off a bit more.
+
+\typebuffer[c]
+
+The \type {point ... on} operation is a \METAFUN\ macro that takes a dimension.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d]
+\stoplinecorrection
+
+In order to save you some typing, \METAFUN\ provides a macro \type {cutends} that
+does the same job:
+
+\typebuffer[cc]
+
+This time we draw the path in a different order:
+
+\typebuffer[dd]
+
+That way we hide the still remaining overlapping part of the line.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,cc,dd]
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title={Directions}]
+
+\index{directions}
+
+Quite often you have to tell \METAPOST\ in what direction a line should be drawn.
+A direction is specified as a vector. There are four predefined vectors: \type
+{up}, \type {down}, \type {left}, \type {right}. These are defined as follows:
+
+\starttyping
+pair up, down, left, right ;
+up = -down = (0,1) ; right = -left = (1,0) ;
+\stoptyping
+
+We can use these predefined pairs as specifications and in calculations.
+
+\startbuffer
+dotlabel.top("up"   , up    * 1cm) ;
+dotlabel.bot("down" , down  * 1cm) ;
+dotlabel.lft("left" , left  * 1cm) ;
+dotlabel.rt ("right", right * 1cm) ;
+
+drawoptions (withpen pencircle scaled .25mm withcolor .625 red) ;
+
+drawarrow origin -- up    * 1cm ;
+drawarrow origin -- down  * 1cm ;
+drawarrow origin -- left  * 1cm ;
+drawarrow origin -- right * 1cm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+This graphic can also be defined in a more efficient (but probably more cryptic)
+way. The next definition demonstrates a few nice tricks. Instead of looping over
+the four directions, we loop over their names. Inside the loop we convert these
+names, or strings, into a pair by scanning the string using \type {scantokens}.
+The \type {freedotlabel} macro is part of \METAFUN\ and takes three arguments: a
+label string (or alternatively a picture), a point (location), and the \quote
+{center of gravity}. The label is positioned in the direction opposite to this
+center of gravity.
+
+\startbuffer
+pair destination ;
+for whereto = "up", "down", "left", "right" :
+  destination := scantokens(whereto) * 1cm ;
+  freedotlabel(whereto, destination, origin) ;
+  drawarrow origin -- destination
+    withpen pencircle scaled .25mm withcolor .625 red ;
+endfor ;
+\stopbuffer
+
+\typebuffer
+
+So, in this code fragment, we use the string as string and (by means of \type
+{scantokens}) as a point or vector.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The previous definition is a stepping stone to the next one. This time we don't
+use points, but the \type {dir} command. This command converts an angle into an
+unitvector.
+
+\startbuffer
+pair destination ;
+for whereto = 0 step 30 until 330 :
+  destination := dir(whereto) * 1.5cm ;
+  freedotlabel(decimal whereto, destination, origin) ;
+  drawarrow origin -- destination
+    withpen pencircle scaled .25mm withcolor .625 red ;
+endfor ;
+\stopbuffer
+
+\typebuffer
+
+In \METAPOST\ the angles go counter clockwise, which is not that illogical if you
+look at it from the point of view of vector algebra.

+{\em Unless you really want to know all details, you can safely skip this

+% Later we will discuss in detail how you can use either \METAPOST\ or \TEX\ to
+% typeset text (\in {section} [sec:text] and \in {chapter} [sec:typesetting]), so

+%
+% \typebuffer[mp]

+%
+% \startlinecorrection[blank]
+% \midaligned{\processMPbuffer[mp]}
+% \stoplinecorrection
+%
+% The same string typeset by \TEX\ shows up as:
+%
+% \blank
+% \midaligned{this string will become a sequence of glyphs (\TeX)}
+% \blank
+%
+% The following \METAPOST\ features are not covered by the \METAPOST\ manual, but
+% most of them are discussed in the appendix of the \type {graph} package written
+% by John Hobby.
+%
+%It is possible to disassemble a picture by means of a special for loop using the
+%\type {within} specifier. The following code walks over a picture and draws the
+%components with their bounding boxes.
+%
+% \startbuffer[show]
+% for i within currentpicture :
+%   draw boundingbox i withcolor .625yellow ;
+% endfor ;
+% \stopbuffer
+%
+% \typebuffer[show]
+%
+% We can use the disassemble loop feature to look into the previously shown
+% example text.
+%
+% \startlinecorrection[blank]
+% \processMPbuffer[mp,show]
+% \stoplinecorrection
+%
+% The second line is typeset by \TEX. The resulting \DVI\ code is converted into a
+% series of pictures, which \METAPOST\ pastes into one picture. You may also notice
+% that in the set of pictures that originate in \TEX, the space is replaced by a
+% shift (this is because \TEX\ knows no space).
+%
+% An interesting aspect of this \quote {loop over a picture} feature, is that it
+% can provide insight in how \TEX\ is composing a paragraph.
+%
+% \startbuffer
+% draw btex \framed[width=fit,align=middle]{\input tufte \relax} etex ;
+% for i within currentpicture :
+%   draw boundingbox i withpen pencircle scaled .2pt withcolor .625yellow ;
+% endfor ;
+% \stopbuffer
+%
+% \startlinecorrection[blank]
+% \processMPbuffer
+% \stoplinecorrection
+%
+% You may also notice, that rules produced by \TEX\ are converted to straight line
+% segments. Because the line extends 50\% of its linewidth beyond a point, there is
+% a slight overshoot. This picture was defined in a few lines:
+%
+% \typebuffer

+% You can ask for the number of components with \type {length}. A component can be
+% a stroked or filled path, or a text resulting from an \type {infont} operation.
+% If the (last) path is a clip path, or when the whole picture has a forced
+% boundingbox, the picture is treated as a whole. We will demonstrate this later.
+
+We can decompose \METAPOST\ pictures using a \type {within} loop. You may wonder
+if such a \type {within} loop construct has any real application, and as you can
+expect, it has. In \in {section} [sec:color circles] a macro is defined that
+draws a colored circle. If you want the inverted alternative, you can pass the
+inverted color specification, but wouldn't it be more convenient if there was an
+operator that did this for you automatically? Unfortunately there isn't one so we
+have to define one ourselves in a macro.
+
+\startbuffer
+colorcircle(4cm,(.4,.6,.8),(.4,.8,.6),(.6,.4,.8)) ;
+addto currentpicture also inverted currentpicture shifted (5cm,0) ;

+
+These circles were drawn using:
+
+\typebuffer
+
+When we \type {draw} a path, or stroke a path, as it is called officially, we
+actually perform an addition:
+
+\starttyping
+addto currentpicture doublepath somepath
+\stoptyping
+
+The \type {fill} command is actually:
+
+\starttyping
+addto currentpicture contour somepath
+\stoptyping
+
+We will need both \type {doublepath} and \type {contour} operations in the
+definition of \type {inverted}.
+
+When \METAPOST\ has digested a path into a picture, it keeps track of some
+characteristics. We can ask for them using \type {part...} operators. The
+following operators can be applied to a transform vector (one of \METAPOST's data
+types), but also to a picture. Say that we have drawn a circle:
+
+\startbuffer[a]
+draw fullcircle
+  xscaled 3cm yscaled 2cm
+  dashed dashpattern(on 3mm off 3mm)
+  withpen pencircle scaled 1mm
+  withcolor .625red ;
+picture p ; p := currentpicture ;
+\stopbuffer
+
+\typebuffer[a]
+
+This circle looks like:
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+We can now ask for some of the characteristics of \type {currentpicture}, like
+its color. We could write the values to the log file, but it is more convenient
+to put them on paper.
+
+\startbuffer[b]
+label.rt("redpart: "   & decimal redpart   p, (4cm,+.5cm)) ;
+label.rt("greenpart: " & decimal greenpart p, (4cm,  0cm)) ;
+label.rt("bluepart: "  & decimal bluepart  p, (4cm,-.5cm)) ;
+\stopbuffer
+
+\typebuffer[b]
+
+Here the \type {&} glues strings together, while the decimal operator converts a
+number into a string.
+
+The result has no typographic beauty |<|keep in mind that here we use \METAPOST\
+to typeset the text|>|but the result serves its purpose.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+We can also ask for the path itself (\type {pathpart}), the pen (\type {penpart})
+and the dashpattern (\type {dashpart}), but these can only be assigned to
+variables of the corresponding type.
+
+A path can be stroked or filled, in which case it is a cyclic path. It can have a
+non natural bounding box, be a clip path, consist of line segments or contain
+text. All these characteristics can be tested.
+
+\startbuffer[b]

+
+Clip paths and bounding boxes are kind of special in the sense that they can
+obscure components. The following examples demonstrate this. In case of a clip
+path or bounding box, the \type {pathpart} operator returns this path. In any
+case that asking for a value does not make sense |<|a clipping path for instance
+has no color|>| a zero (null) value is returned.

+
+The textual capabilities built in \METAPOST\ are rather limited but in \CONTEXT\
+we have overloaded the relevant operators. There we hook into the normal font
+handler. The native text related operators are:
+
+\starttyping
+draw "MetaFun" infont "somefont" scaled 2 rotated 30 slanted .5 ;
+draw btex MetaFun etex scaled 2 rotated 30 slanted .5 ;
+\stoptyping
+
+The \type {infont} operator directly calls for a font and in stock \METAPOST\ is
+limited to (eight bit) \TYPEONE\ fonts. In \CONTEXT\ you can do this:
+
+\startbuffer[a]
+draw "MetaFun" infont "SerifBold*default" xscaled 5 rotated 5 slanted .5 ;
+\stopbuffer
+
+\typebuffer[a]
+
+The specification is a regular \CONTEXT\ font specification.
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+The \type {btex ... etex} variant in normal \METAPOST\ delegates to \TEX\ and in \MKII\
+indeed we filter them and process them between runs (or at runtime). In \MKIV\ they are
+also handled by \TEX\ but in an even more integrated and immediate way.
+
+The two primitives \type {textpart} and \type {fontpart} that can be used to disassemble
+a picture don't apply to \METAFUN\ as contrary to \METAPOST\ we don't convert the result
+to a picture. In later chapters we will discuss text in more detail.
+
+From the previous examples it may be clear that each picture has some associated
+data stored with it. From the \type {bounded} boolean test we can conclude that
+the bounding box is part of this data. Internally \METAPOST\ keeps track of two
+bounding boxes: the natural one, and the forced one. The forced one is actually a
+component of the picture which applies to all previously added graphics. You can
+calculate the bounding box from the \type {llcorner} and \type {urcorner} or if
+you like \type {ulcorner} and \type {lrcorner} and the \METAFUN\ command \type
+{boundingbox} does so.
+
+The four corners that make up the bounding box are either the natural ones, or
+the ones forced by \type {setbounds}. You can force \METAPOST\ to report the
+natural ones by setting \type {truecorners} to~1. The next example demonstrates
+this feature.
+
+\startbuffer
+pickup pencircle scaled 2mm ; path p, q ;
+draw fullcircle
+  scaled 4cm slanted .5 withcolor .625white ;
+setbounds currentpicture to
+  boundingbox currentpicture enlarged -5mm ;
+interim truecorners := 0 ; p := boundingbox currentpicture ;
+interim truecorners := 1 ; q := boundingbox currentpicture ;
+pickup pencircle scaled 1mm ;
+draw p withcolor .625red ;
+draw q withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer
+
+We use \type {interim} because \type {truecorners} is an internal \METAPOST\
+variable.

+% % we already redefined infont so it's kind of dangerous to provide this example
+%
+% Since \METAPOST\ can handle fonts (it can even generate font metric files) it is
+% no surprise that we can also ask for the natural size of a font. For this we use
+% \type {fontsize}. However, you should beware of the fact that the size reported
+% is in base points. Since this is \METAPOST's native unit, this is no problem in
+% calculations, but it may look confusing when you \type {show} this size on your
+% terminal and get less that 10 reported for a \type {cmr10} font.
+%
+% \starttyping
+% show fontsize "cmr10" ;
+% \stoptyping
+%
+% In order to demonstrate that \type {fontsize} is useful, we extend the \type
+% {infont} command. In the process we show a few macro definition tricks. What we
+% want is a \TEX\ like specification of a font size:
+%
+% \startbuffer[txt]
+% draw "MetaFun" infont defaultfont at 20pt ;
+% \stopbuffer
+%
+% \typebuffer[txt]
+%
+% We can store the current meaning of a primitive or macro in a new macro. We do so
+% with \type {infont}:
+%
+% \startbuffer[a]
+% let normalinfont = infont ;
+% \stopbuffer
+%
+% \typebuffer[a]
+%
+% We can only know the size if we know the name of the font, so we have to redefine
+% \type {infont} to pick up this name.
+%
+% \startbuffer[b]
+% numeric lastfontsize ; lastfontsize = fontsize defaultfont ;
+% \stopbuffer
+%
+% \startbuffer[c]
+% primarydef infont primary name = % patched: def should work too
+%   hide(lastfontsize := fontsize name)
+%   normalinfont name
+% enddef ;
+% \stopbuffer
+%
+% \typebuffer[c]
+%
+% Because we are replacing an operator, and since \METAPOST\ expects one, we have
+% to use \type {def} instead of \type {vardef} (which is actually a kind of
+% variable). For the same reason, we have to pick up a \type {primary}. If we would
+% use a \typ {expr name}, we would end up in an unwanted look ahead. The \type
+% {hide} macro hides the assignment and makes this macro behave like a \type
+% {vardef} with respect to hiding expressions. We may not put a semi colon after
+% the \type {)} because it would stop \METAPOST\ from reading on, and thereby
+% invoke an error message.
+%
+% We can now define \type {at}. This macro picks up an expression (which can be
+% more than just a number) and return a scale transform that normalizes the given
+% size to the design size.
+%
+% \startbuffer[d]
+% def at expr size =
+%   scaled (size/lastfontsize)
+% enddef ;
+% \stopbuffer
+%
+% \typebuffer[d]
+%
+% Because this macro is defined global, and therefore can be used apart from \type
+% {infont}, we predefine the size:
+%
+% \typebuffer[b]
+%
+% When defined this way \type {at} a comfortable 20 points, the string \type
+% {MetaFun} comes out as follows:

+In most cases a path ends up being drawn or filled. When filling a path, it
+doesn't matter in what direction the path runs, as long as it's closed you're

+In the case of a normal fill, the non||zero winding rule is applied: a winding
+number is calculated by subtracting 1 each time the line (from inside an area to
+someplace outside) is crossed clockwise while 1 is added each time we cross
+anti||clockwise. When the total is non zero the area is filled. Here we run in one
+direction and therefore we always get a fill. In the previous example where we
+used a reverse, an anti||clockwise crossing was nilled by a clockwise one.
+
+The leftmost shape uses \type {eofill} and therefore the odd||even rule gets
+applied. This time we follow the line and when it gets crossed en even number of
+times the area will not be filled.
+
+A glyph is often constructed from more than one path and eventually the shape is
+filled with an odd||even fill (\type {eofill}) operation. Take the following
+sequence:
+
+\startbuffer
+pickup pencircle scaled 1mm ;

+The arrow is made up out of two pieces and each piece gets a different shade of

+  if error : message "pencils are not supported here" fi ;
+enddef ;
+mydraw fullcircle scaled 10cm withpencil sharp ;
+\stoptyping
+
+Here, setting the boolean normally interferes with the draw operation, but by
+hiding the assignment, this code becomes valid. This code will bring the message
+to your terminal and log file.
+
+Once you start using expressions you have a good chance of encountering messages
+with regard to redundant expressions. The following code is for instance a
+recipe for problems:
+
+\starttyping
+z1 = (1,0) ; z1 = (2,0) ;
+\stoptyping
+
+Changing the \type {=} into \type {:=} helps, but this may not be what you want.
+
+Because the \type {z}||variables are used frequently, they are reset each figure.
+You can also reset them yourself, using the \type {clearxy} macro. The \METAFUN\
+version clears all \type {z}||variables, unless you explictly specify what
+variables to reset. \footnote {This version resulted from a discussion on the
+\METAFONT\ discussion list and is due to Bogus\l{}aw Jackowski.} If you want to
+play with this macro, see what happens when you run the following code:
+
+\starttyping
+show x0 ; z0 = (10,10) ;
+show x0 ; x0 := whatever ; y0 := whatever ;
+show x0 ; z0 = (20,20) ;
+show x0 ; clearxy 0 ;
+show x0 ; z0 = (30,30) ;
+\stoptyping
+
+So, the following calls are all legal:
+
+\starttyping
+clearxy ; clearxy 1 ; clearxy 1, 8, 10 ;
+\stoptyping
+
+Keep in mind that for each figure a full clear is done anyway. You should not
+confuse this command with \type {clearit}, which clears \type {currentpicture}.
+
+\stopsection
+
+\startsection[title={\TeX\ versus \MetaPost}]
+
+If you are defining your own \TEX\ and \METAPOST\ macros, you will notice that
+there are a couple of essential differences between the two macro languages. In
+\TEX\ the following code is invalid. \footnote {In \ETEX\ the calculation can be
+done in less lines using a \type {\numexpr}.}
+
+\starttyping
+\def\fancyplied#1%
+  {\ifnum#1=0
+     \message{zero argument}%
+   \fi
+   \count0=#1 \multiply \count0 by \count0
+   \count2=#1 \multiply \count2 by 2
+   \count4=#1 \divide   \count4 by 2
+   \advance \count0 by \count2
+   \advance \count0 by \count4
+   \count4 }
+\hskip \fancyplied{3} pt
+\stoptyping
+
+This is because \TEX\ is very strict in what tokens it expects next. In
+\METAPOST\ however, you can use \type {vardef}'d macros to hide nasty
+intermediate calculations.
+
+\starttyping
+vardef fancyplied expr x =
+  if x=0 : message "x is zero" ; (x*x+2x+x/2)
+enddef ;
+a := a shifted (fancyplied 3pt,0) ;
+\stoptyping
+
+Hiding intermediate calculations and manipulations is a very strong point of
+\METAPOST.
+
+Another important difference between both languages is the way grouping is
+implemented. Because \TEX\ is dealing with a flow of information, strong grouping
+is a must and therefore part of the language. Occasionally you run into
+situations where you wished that you could reach over a group (for instance in
+order to pass a value).
+
+In \METAPOST\ grouping behaves quite different. First of all, it provides the
+mechanism that hides processing from the current flow. The previously mentioned
+\type {vardef} is implicitly grouped. Contrary to \TEX, in \METAPOST\ all
+assignments are global by default, even in a group. If you assign a variable
+inside a group it is persistent unless you first save the variable (or macro)
+using the \type {save} operator.
+
+So, in the next code snippet, the value of \type {\value} inside the box is {\em
+no} but after the box is typeset, it will be {\em yes} again.
+
+\starttyping
+\def\value{yes} \hbox{\def\value{no}\value} \value
+\stoptyping
+
+To make a value local in \METAPOST, the following code is needed.
+
+\starttyping
+string value ; value := "yes" ;
+def intermezzo
+  begingroup ;
+    save value ; string value ; value := "no" ;
+  endgroup ;
+enddef ;
+\stoptyping
+
+Once you start writing your own \METAPOST\ macros, you will appreciate this
+\quote {always global} behaviour. As with other differences between the two
+languages, they make sense if you look at what the programs are supposed to do.
+
+\stopsection
+
+\startsection[title={Internals and Interims}]
+
+\index{internals}
+\index{interims}
+
+Related to grouping is the internal numeric datatype. When numeric variables are
+defined as interim, you can quickly overload them inside a group.
+
+\starttyping
+newinternal mynumber ; mynumber := 1 ;
+
+begingroup ; ... interim mynumber := 0 ; ... ; endgroup ;
+\stoptyping
+
+You can only \type {interim} a variable if it is already defined using \type
+{newinternal}.
+
+Among the \METAPOST\ macros is one called \type {drawdot}. This macro is kind of
+redundant because, at least at first sight, you can use draw to achieve the same
+result. There is however a very subtle difference: a dot is slightly larger than
+a drawn point. We guess that it's about the device pixel, so you may not even
+notice it. It may even be due to differences in accuracy of the methods to render
+them.
+
+\startbuffer
+pickup pencircle scaled 50pt ;
+drawdot origin shifted (-120pt,0) ; draw origin shifted (-60pt,0) ;
+drawdot origin ; draw origin withcolor white ;

+
+\startsection[title=Named colors]
+
+The \type {withcolor} operator accepts a color expression but in \METAFUN\ it
+also accepts a string indicating a color defined at the \TEX\ end. Most helpers
+that deal with colors are able to deal with named colors as well. Here are some
+examples. First we define a few colors:
+
+\startbuffer
+\definecolor[MyColor1][r=.5]
+\definecolor[MyColor2][g=.5]
+\definecolor[MyColor3][b=.5]
+\definecolor[MyColor4][s=.8]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Here we access them:
+
+\startbuffer
+fill fullcircle scaled 12 withcolor "MyColor1" ;
+fill fullcircle scaled 10 withcolor "MyColor2" ;
+fill fullcircle scaled  8 withcolor complementary "MyColor3" ;
+fill fullcircle scaled  6 withcolor complemented "MyColor3" ;
+fill fullcircle scaled  4 withcolor "MyColor4" randomized 2 ;
+fill fullcircle scaled  2 withcolor "MyColor4" randomized 2 ;
+addbackground
+    withcolor .5[resolvedcolor("MyColor4"),resolvedcolor("MyColor2")] ;
+currentpicture := currentpicture ysized 4cm ;
+\stopbuffer
+
+\typebuffer
+
+And get:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title=Formatted text]
+
+Text support in \METAFUN\ has evolved quite a bit over years. For compatibility
+reasons we keep old methods around but in practice one can probably do all with
+the following:
+
+\starttabulate[|T|p|]
+\NC textext[.anchor](str)        \NC position a text relative to the origin \NC \NR
+\NC thetextext[.anchor](str,pos) \NC position a text relative to the given position \NC \NR
+\NC rawtextext[.anchor](str,pos) \NC idem but with less checking \NC \NR
+\stoptabulate
+
+If needed all functionality could be combined in one call (textext) but we keep
+it this way.
+
+You need to keep in mind that text in \METAPOST\ is not a first class object but
+something virtual that is known to \METAFUN\ as something with path like properties
+but is actually dealt with in the backend. This means that timing is important.
+
+\starttyping
+\startMPinitializations
+picture p ; p := image(draw textext("Foo"););
+\stopMPinitializations
+
+\startMPcode
+    picture q ; q := image(draw textext("Bar"););
+    picture r ; r := image(draw textext("Gnu"););
+    draw p ;
+    draw q shifted (2cm,0) ;
+    draw r shifted (4cm,0) ;
+\stopMPcode
+\stoptyping
+
+This will work out well because an initialization is part of a figure, but
+this will fail:
+
+\starttyping
+\startMPinclusions
+picture p ; p := image(draw textext("Foo"););
+\stopMPinclusions
+\stoptyping
+
+because inclusions happen before the local textexts get initialized and
+due to the multipass implementation are not seeN a second time. The order of
+processing is:
+
+\starttabulate[|l|c|c|]
+\BC action          \BC first pass  \BC second pass \NC \NR
+\NC definitions     \NC yes \NC     \NC \NR
+\NC extensions      \NC yes \NC     \NC \NR
+\NC inclusions      \NC yes \NC     \NC \NR
+\NC begin figure    \NC yes \NC yes \NC \NR
+\NC initializations \NC yes \NC yes \NC \NR
+\NC metapost code   \NC yes \NC yes \NC \NR
+\NC end figure      \NC yes \NC yes \NC \NR
+\stoptabulate
+
+The graph package (that comes with \METAPOST) has some pseudo typesetting on
+board needed to format numbers. Because we don't want to interfere with the
+definitions of macros used in that package we provide another set of macros for
+formatting: \type {fmttext}, \type {thefmttext} and \type {rawfmttext}.
+
+\startbuffer
+\startMPcode
+draw thefmttext("\bf@3.2f done",123.45678) withcolor darkred ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+Here we pass one variable to the format but there can be more: \inlinebuffer. In
+\LUA\ the \type {%} is used as format directive but that does not work well in
+\TEX\ and \LUA\ which is why we use \type {@} instead. The formatting is done
+with the formatters subsystem which is an extension to the regular \LUA\ \type
+{format} function. More information can be found in \type {clf-mkiv.pdf} but one
+extension is not mentioned there: \type {%!texexp!}. This directive takes one
+argument by default but optionally can take one or two extra arguments: the
+format of the base number and one for the exponent. The following code
+demonstrates this:
+
+\startbuffer
+\startMPcode{doublefun}
+draw image (
+  draw thefmttext.rt("@!texexp!", 10.4698E30,              (0,-1LineHeight)) ;
+  draw thefmttext.rt("@1!texexp!",10.4698E30,              (0,-2LineHeight)) ;
+  draw thefmttext.rt("@2!texexp!",10.4698E30,"@2.3f",      (0,-3LineHeight)) ;
+  draw thefmttext.rt("@3!texexp!",10.4698E30,false,"@2i",  (0,-4LineHeight)) ;
+  draw thefmttext.rt("@3!texexp!",10.4698E30,"@2.3f","@2i",(0,-5LineHeight)) ;
+) withcolor darkblue ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+We switch to double mode because we use large numbers.
+
+\startlinecorrection[blank]
+    \getbuffer
+\stoplinecorrection
+
+Of course this extra formatter is also supported in the \type {context}
+command:
+
+\startbuffer
+\startluacode
+context("%!texexp!, ",    10.4698E30)
+context("%1!texexp!, ",   10.4698E30)
+context("%2!texexp!, ",   10.4698E30,"@2.3f")
+context("%3!texexp! and ",10.4698E30,false,"@2i")
+context("%3!texexp!",     10.4698E30,"@2.3f","@2i")
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+This gives: \inlinebuffer .
+
+\stopsection
+
+\startsection[title=Lists (aka suffixed variables)]
+
+Sometimes graphics are constructed using lists. There are a few helpers (and
+maybe there will be some more) that can make things a bit easier. Say that we
+do this:
+
+\startbuffer
+pair a[] ;
+a[1] := (0,0) ; a[2] := (1,0) ;
+a[3] := (1,1) ; a[4] := (0,1) ;
+a[5] := (1,1) ; a[6] := (2,0) ;
+
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625red ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The \type {topath} macro converts the list into a path, in this case an ugly one.
+
+Say that we want to get rid of the sixth entry. For that we can use the \type
+{dispose} macro. You can use the dispose for any type (except a macro).
+
+\startbuffer
+dispose(a[6]) ;
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+We still have some duplicate entries here:
+
+\startbuffer
+dispose(a[6]) ;
+drawpoints topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625red ;
+drawpointlabels topath(a,--) ysized 2cm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+These can be removed with:
+
+\startbuffer
+uniquelist(a) ;
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625yellow ;
+drawpoints topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625red ;
+drawpointlabels topath(a,--) ysized 2cm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Sometimes a list needs to be sorted and here is the solution:
+
+\startbuffer
+sortlist(a,nothing) ;
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 1mm
+    withcolor .625red ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The second argument can be an operator that takes a pair variable:
+
+\startbuffer
+sortlist(a,xpart) ;
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 3mm
+    withcolor .625red ;
+sortlist(a,ypart) ;
+draw topath(a,--) ysized 2cm
+    withpen pencircle scaled 2mm
+    withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Constructing a list can be sped up with the \type {tolist} macro.
+
+\startbuffer
+pair a[], b[], c[], d[] ;
+tolist(a,1,(0,0),(1,0),(1,1),(0,1)--(1,1)--(2,2)) ;
+tolist(b,0,(0,0),(1,0),(1,1),(0,1)--(1,1)--(2,2)) ;
+tolist(c,(0,0),(1,0),(1,1),(0,1)--(1,1)--(2,2)) ;
+tolist(d,(0,0),(1,0),(1,1)) ;
+
+draw image (
+    draw topath(a,--) shifted (0,0) ;
+    draw topath(b,--) shifted (3,0) ;
+    draw topath(c,--) shifted (6,0) ;
+    draw topath(d,--) shifted (9,0) ;
+) ysized 2cm withpen pencircle scaled 1mm withcolor .625red ;

+\processMPbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title=Segmented paths]
+
+\index {segmented paths}There are all kind of helpers in \METAFUN\ and some are
+discussed here. In \in {figure} [fig:segmentedpaths] we see a few macros that
+return a (smooth) path made from segments. You can for instance use these to do
+things that use the points on a path, like anchoring text.
+
+\startbuffer
+def DrawSomePath(text t) =
+    drawpath        t withcolor .625red ;
+    drawpoints      t withcolor white ;
+    drawpointlabels t ;
+enddef ;
+
+DrawSomePath(circularpath(5) scaled 12cm) ;
+DrawSomePath(squarepath  (5) scaled  8cm) ;
+DrawSomePath(linearpath  (5) scaled  4cm) ;

+    \processMPbuffer
+\stopplacefigure
+
+\index {crossing paths}The following examples demonstrates two mechanisms. In the
+image two paths are drawn on top of each other but one of them has holes where
+the other one crosses. The \type {crossingunder} macro was written by Alan
+Braslau as part of the node based diagram builder. In the process the arrow
+drawing code was adapted to accept a picture.
+
+\startbuffer[a]
+drawarrow image (
+    draw ((fullcircle scaled 2.25cm) crossingunder (fullsquare scaled 2cm))
+        withpen pencircle scaled 1mm withcolor .625green ;

+    draw ((fullcircle scaled 5cm) crossingunder (fullsquare scaled 4cm))
+        withpen pencircle scaled 1mm withcolor .625yellow ;
+) ;
+\stopbuffer
+
+\startbuffer[b]
+drawarrow image (
+    draw ((fullsquare scaled 2cm) crossingunder (fullcircle scaled 2.25cm))
+        withpen pencircle scaled 1mm withcolor .625blue ;
+    draw  (fullcircle scaled 2.25cm)
+        withpen pencircle scaled 1mm withcolor .625green ;
+) ;
+drawarrow image (

+        withpen pencircle scaled 1mm withcolor .625red ;

+\stopbuffer
+
+\typebuffer[a]
+
+The next variant uses a different order:
+
+\typebuffer[b]
+
+The results are shown in \in {figure} [fig:crossingunder]. The internal variable
+\type {crossingscale} can be used to make the gap wider or narrower. The gap has
+a default value of 20.

+
+I owe much inspiration to both my parents. My mother Jannie constantly
+demonstrated me that computer graphics will never improve nature. She also
+converted one of my first \METAPOST\ graphics into a patchwork that will remind
+me forever that handcraft is more vivid than computer artwork. My father Hein has
+spent a great deal of his life teaching math, and I'm sure he would have loved
+\METAPOST. I inherited his love for books. I therefore dedicate this document to
+them.

+
+When reading this manual, you may be tempted to test the examples shown. This can
+be done in several ways. You can make a file and process that file by \METAPOST.
+Such a file looks like:
+
+\starttyping
+beginfig(1) ;
+  fill fullcircle scaled 5cm withcolor red ; % a graphic
+endfig ;
+
+end .
+\stoptyping
+
+Don't forget the semi||colons that end the statements. If the file is saved as
+\type {yourfile.mp}, then the file can be processed. Before we process this file,
+we first need to load some basic \METAPOST\ definitions, because the built in
+repertoire of commands is rather limited. Such a set is called a format. The
+standard format is called {metapost} but we will use a more extensive set of
+macros \type {metafun}. In the past such a set was converted into a \type {mem}
+file and running the above file was done with:
+
+\starttyping
+mpost --mem=metafun.mem yourfile
+\stoptyping
+
+However, this is no longer the case and macros need to be loaded at startup as
+follows:
+
+\starttyping
+mpost --ini metafun.mpii yourfile.mp
+\stoptyping
+
+Watch the suffix \type {mpii}: this refers to the stand alone, the one that
+doesn't rely on \LUATEX.
+
+After the run the results are available in \type {yourfile.1} and can be viewed
+with \GHOSTSCRIPT. You don't need to close the file so reprocessing is very
+convenient.
+
+Because we will go beyond standard \METAPOST, we will use the \type {mpiv} files.
+These work with the library which in turn means that we will run from within
+\CONTEXT. This has the advantage that we also have advanced font support at our
+hands. In that case, a simple file looks like:
+
+\starttyping
+\starttext
+  \startMPpage
+    fill fullcircle scaled 5cm withcolor red ;
+  \stopMPpage
+  \startMPpage
+    fill unitsquare scaled 5cm withcolor red ;
+  \stopMPpage
+\stoptext
+\stoptyping
+
+If the file is saved as \type {yourfile.tex}, then you can produce a \PDF\ file
+with: \footnote {In fact, you could also process the \METAPOST\ file directly
+because the \type {context} script will recognize it as such and wrap it into
+a page.}
+
+\starttyping
+context yourfile
+\stoptyping
+
+The previous call will use \LUATEX\ and \CONTEXT\ \MKIV\ to produce a file with
+two pages using the built in \METAPOST\ library with \METAFUN. When you use this
+route you will automatically get the integrated text support shown in this
+manual, including \OPENTYPE\ support. If one page is enough, you can also say:
+
+\starttyping
+\startMPpage
+fill fullcircle scaled 5cm withcolor red ;
+\stopMPpage
+\stoptyping
+
+So when you have a running \CONTEXT\ on your system you don't need to bother
+about installing \METAPOST\ and running \METAFUN.
+
+We will use lots of color. Don't worry if your red is not our red, or your yellow
+does not match ours. We've made color definitions to match the overall design of
+this document, but you should feel free to use any color of choice in the
+upcoming examples.
+
+By default, \CONTEXT\ has turned its color mechanism on. If you don't want your
+graphics to have color, you should say:
+
+\starttyping
+\setupcolors[state=stop]
+\stoptyping
+
+but in todays documents color is so normal that you will probably never do that.
+Because \METAFUN\ hooks into the \CONTEXT\ color mechanism, you can also use its
+color space and conversion related features.
+
+You need to keep in mind that just like \CONTEXT\ \MKII\ is frozen, the \type
+{mpii} macros are also not extended. From now on we assume that you use \CONTEXT\
+\MKIV\ which exclusively uses \type {mpiv} macros.
+
+Even if you want to use \METAFUN\ but not \CONTEXT, you can still best use the
+mentioned page method as it will give you decent text processing. You need to
+know (and use) only a few \CONTEXT\ commands then.

+
+\index{debugging}
+
+\startintro
+
+Those familiar with \CONTEXT\ will know that it has quite some visual debugging
+features build in. So, what can you expect of the \METAPOST\ macros that come
+with \CONTEXT ? In this chapter we will introduce a few commands that show some
+insight in what \METAPOST\ is doing.
+
+\stopintro
+
+\startsection[title=Showing paths]
+
+Since the outcome of \METAPOST\ code is in many respects more predictable than
+that of \TEX\ code, we don't need that advanced visual debugging features.
+Nevertheless we provide a few, that are all based on visualizing paths.
+
+\startbuffer
+path p ; p := fullcircle scaled 4cm ;
+drawpath p ; drawpoints p ; drawpointlabels p ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+This visualization is achieved by using dedicated drawing commands:
+
+\typebuffer
+
+Since control points play an important role in defining the shape, visualizing
+them may shed some insight in what \METAPOST\ is doing.
+
+\startbuffer
+path p ; p := fullcircle xscaled 4cm yscaled 3cm ;
+drawpath p ; drawcontrollines p ;
+drawpoints p ; drawcontrolpoints p ; drawpointlabels p ;
+\stopbuffer
+
+\typebuffer
+
+The pre and post control points show up as small dots and are connected to their
+parent point with thin lines.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+You can deduce the direction of a path from the way the
+points are numbered, but using an arrow to indicate the
+direction is more clear.
+
+\startbuffer
+path p ; p := fullcircle xscaled 4cm yscaled 3cm ;
+drawarrowpath p ; drawcontrollines p ;
+drawpoints p ; drawcontrolpoints p ; drawpointlabels p ;
+\stopbuffer
+
+\typebuffer
+
+The \type {drawarrowpath} is responsible for the arrow. Especially when you are
+in the process of defining macros that have to calculate intersections or take
+subpaths, knowing the direction may be of help.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The next table summarizes the special drawing commands:
+
+\starttabulate[|lT|l|]
+\HL
+\NC drawpath           \NC the path                         \NC \NR
+\NC drawarrowpath      \NC the direction of the path        \NC \NR
+\NC drawcontrollines   \NC the lines to the control points  \NC \NR
+\NC drawpoints         \NC the points that make up the path \NC \NR
+\NC drawcontrolpoints  \NC the control points of the points \NC \NR
+\NC drawpointlabels    \NC the numbers of the points        \NC \NR
+\HL
+\stoptabulate
+
+You can set the characteristics of these like you set \type {drawoptions}. The
+default settings are as follows:
+
+\starttyping
+drawpathoptions   (withpen pencircle scaled 5   withcolor .8white) ;
+drawpointoptions  (withpen pencircle scaled 4   withcolor   black) ;
+drawcontroloptions(withpen pencircle scaled 2.5 withcolor   black) ;
+drawlineoptions   (withpen pencircle scaled 1   withcolor .5white) ;
+drawlabeloptions  () ;
+\stoptyping
+
+Two more options are \type {draworiginoptions} and \type {drawboundoptions} which
+are used when visualizing the bounding box and origin.
+
+\startbuffer
+swappointlabels  := true ;
+path p ; p := fullcircle xscaled 4cm yscaled 3cm ;
+drawarrowpath p ; drawcontrollines p ;
+drawpoints p ; drawcontrolpoints p ; drawpointlabels p ;
+drawboundingbox p ; draworigin ;
+\stopbuffer
+
+\typebuffer
+
+In this example we have set \type {swappointlabels} to change the place of the
+labels. You can set the variable \type {originlength} to tune the appearance of
+the origin.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+You can pass options directly, like you do with \type {draw} and \type {fill}.
+Those options override the defaults.
+
+\startbuffer
+path p ; p := fullcircle xscaled 6cm yscaled 3cm rotated 15 ;
+drawarrowpath     p ;
+drawcontrollines  p withcolor .625red ;
+drawpoints        p withcolor .625yellow ;
+drawcontrolpoints p withcolor .625yellow ;
+drawpointlabels   p withcolor .625yellow ;
+drawboundingbox   p ;
+draworigin          withcolor .625red ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Here we used the options:
+
+\typebuffer
+
+Sometimes it makes sense to draw a simple coordinate system, and for that purpose
+we have three more macros. They draw axis and tickmarks.
+
+\startbuffer
+drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ;
+\stopbuffer
+
+\typebuffer
+
+The system drawn is based on the bounding box specification of the path passed to
+the macro. You can also draw one axis, using \type {drawxticks} or \type
+{drawyticks}. Here we show the previous command.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+By default, the ticks are placed at .5cm distance, but you can change this by
+setting \type {tickstep} to a different value.
+
+\startbuffer
+tickstep := 1cm ; ticklength := 2mm ;
+drawticks fullsquare xscaled 4cm yscaled 3cm ;
+tickstep := tickstep/2 ; ticklength := ticklength/2 ;
+drawticks fullsquare xscaled 4cm yscaled 3cm ;
+\stopbuffer
+
+\typebuffer
+
+The \type {ticklength} variable specifies the length of a tick. Here we
+manipulated both the variables to get a more advanced system.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+If visualizing a path would mean that we would have to key in al those
+draw||commands, you could hardly call it a comfortable tool. Therefore, we can
+say:
+
+\startbuffer
+drawwholepath fullsquare scaled 3cm rotated 30 randomized 5mm ;
+\stopbuffer
+
+\typebuffer
+
+The \type {drawwholepath} command shows everything except the axis.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+If even this is too much labour, you may say:
+
+\starttyping
+visualizepaths ;
+\stoptyping
+
+This redefines the \type {draw} and \type {fill} command in such a way that they
+also show all the information.
+
+\startbuffer
+visualizepaths ;
+draw fullsquare scaled 3cm rotated 30 randomized 2mm ;
+\stopbuffer
+
+\typebuffer
+
+You may compare this feature to the \type {\showmakeup} command available in
+\CONTEXT, that redefines the \TEX\ primitives that deal with boxes, glues,
+penalties, and alike.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Of course you may want to take a look at the \METAPOST\ manual for its built in
+(more verbose) tracing options. One command that may prove to be useful is \type
+{show}, that you can apply to any variable. This command reports the current
+value (if known) to the terminal and log file.
+
+\startlinecorrection[blank]
+{\showmakeup\processMPbuffer}
+\stoplinecorrection
+
+The previous picture shows what is typeset when we also say \type {\showmakeup}.
+This command visualizes \TEX's boxes, skips, kerns and penalties. As you can see,
+there are some boxes involved, which is due to the conversion of \METAPOST\
+output to \PDF.
+
+\starttyping
+\startlinecorrection[blank]
+... the graphic ...
+\stoplinecorrection
+\stoptyping
+
+The small bar is a kern and the small rectangles are penalties. More details on
+this debugger can be found in the \CONTEXT\ manuals and the documentation of the
+modules involved.
+
+\stopsection
+
+\startsection[title=Comments]
+
+Sometimes, when trouble strikes, you might want to peek in the \PDF\ file to see
+what gets written there. Each graphic is marked with a number but when you
+have many it might make sense to add a comment to help you locate the code.
+
+\startbuffer
+\startMPcode
+    comment("test graphic") ;
+    message("processing a test graphic") ;
+    draw fullsquare scaled 1cm ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+This renders as:
+
+\startlinecorrection[blank]
+    \getbuffer
+\stoplinecorrection
+
+On the console we get these messages:
+
+\starttyping
+metapost > message : processing a test graphic
+metapost > warning : processing a test graphic
+\stoptyping
+
+And in the \PDF\ file we will find:
+
+\starttyping
+% mps graphic 1: begin
+% mps graphic 1: test graphic
+q 0 g 0 G 10 M 1 j 1 J
+0.500000000 w
+-14.173233032 -14.173233032 m
+14.173233032 -14.173233032 l
+14.173233032 14.173233032 l

+-14.173233032 -14.173233032 l
+h S
+0 g 0 G Q
+% mps graphic 1: end
+\stoptyping
+
+Here are some examples of constructed messages:
+
+\starttyping
+message "2:                okay           (done)" ;
+message "1: " & dq      & "okay" & dq & " (done)" ;
+message "3: " & quotation "okay"      & " (done)" ;
+message "3: " & quote     "okay"      & " (done)" ;
+message "4: " & quotation 123         & " (done)" ;
+message "5: " & quotation true        & " (done)" ;
+message "6: " & quote     true        & " (done)" ;
+message "7: " & tostring  true        & " (done)" ;
+message "8: " & tostring  (1,2)       & " (done)" ;
+message "9: " & topair    (1,2)       & " (done)" ;
+\stoptyping
+
+and this is what you get:
+
+\starttyping
+metapost > message : 2: okay (done)
+metapost > message : 1: "okay" (done)
+metapost > message : 3: "okay" (done)
+metapost > message : 3: 'okay' (done)
+metapost > message : 4: "123" (done)
+metapost > message : 5: "true" (done)
+metapost > message : 6: 'true' (done)
+metapost > message : 7: true (done)
+metapost > message : 8: 1 2 (done)
+metapost > message : 9: (1,2) (done)
+\stoptyping
+
+\stopsection
+
+\startsection[title=Pens]
+
+A circular pen is applied to a path in a different way than for instance a
+square pen. Circular pens are mapped onto \POSTSCRIPT\ pens while for other
+pens an outline is calculated that gets filled. Take this code:
+
+\startbuffer[a]
+\startMPcode
+    draw fullcircle xscaled 6cm yscaled 3cm
+        withpen pensquare scaled 5mm rotated 30
+        withcolor .625yellow ;
+\stopMPcode
+\stopbuffer
+
+\startbuffer[b]
+\startMPcode
+    draw envelope pensquare scaled 5mm rotated 30 of
+        (fullcircle xscaled 6cm yscaled 3cm)
+        withpen pencircle scaled 1mm
+        withcolor .375white ;
+\stopMPcode
+\stopbuffer
+
+\startbuffer[c]
+\enabletrackers[metapost.forcestroke]
+\startMPcode
+    draw fullcircle xscaled 6cm yscaled 3cm
+        withpen pensquare scaled 5mm rotated 30
+        withcolor .625red ;
+\stopMPcode
+\disabletrackers[metapost.forcestroke]
+\stopbuffer
+
+\typebuffer[a]
+
+and this:
+
+\typebuffer[b]
+
+and:
+
+\typebuffer[c]
+
+When we overlay these three we get. The envelope only returns the outer curve.
+

+\startchapter[title={This document}]
+
+\startintro
+
+This document is produced in \CONTEXT\ and can serve as an example of how to
+integrate \METAPOST\ graphics into \TEX. In this appendix we will discuss some
+details of producing this document.
+
+\stopintro
+
+We did not use any special tricks, so most of the examples you have seen are
+coded just as shown. We used buffers to ensure that the code used to produce the
+accompanying graphic is identical to the typeset code in the document. Here is an
+example.
+
+\starttyping
+\startbuffer[dummy]
+draw fullcircle
+  xscaled 3cm yscaled 2cm
+  rotatedaround(origin,30)
+  withcolor .625red ;
+\stopbuffer
+\stoptyping
+
+Instead of using \type {\getbuffer}, we used the following command:
+
+\starttyping
+\startlinecorrection[blank]
+\processMPbuffer[dummy]
+\stoplinecorrection
+\stoptyping
+
+The line correction commands take care of proper spacing around the graphic. If
+you want to process more buffers at once, you can pass their names as a comma
+separated list. Alternatively, we could have said:
+
+\starttyping
+\startuseMPgraphic{dummy}
+  draw fullcircle
+    xscaled 3cm yscaled 2cm
+    rotatedaround(origin,30)
+    withcolor .625red ;
+\stopuseMPgraphic
+\stoptyping
+
+When including this graphic, we again take care of spacing.
+
+\starttyping
+\startlinecorrection[blank]
+\useMPgraphic{dummy}
+\stoplinecorrection
+\stoptyping
+
+The first version of this manual was produced with \PDFTEX\ and call|-|outs to
+\METAPOST. Because the number of graphics is large, we processed that version
+using the \type {--automp} directive (at that moment we were using \TEXEXEC). And
+even then runtime was so unconveniently long that updating this manual became
+less and less fun. The current version is produced with \LUATEX\ and \CONTEXT\
+\MKIV, which brings down the runtime (including runtime calls to independent
+\CONTEXT\ runs for the outline examples) to some 45 seconds on a 2.2 Gig Dell
+M90. Given that (at the time of writing this) over 1700 graphics are generated on
+the fly, this is not bad at all. On my current machine, a Dell M6700 with an
+Intel Core i7|-|3840QM running at 2.8 (3.9) Ghz (and Windows~8) the runtime of
+the third version was just above 20 seconds all|-|in and some 25\percent\ less
+when using \LUAJITTEX. When I started with updating to version 4 of this manual,
+I timed about 15 seconds on the same machine (but with Windows-10) which means
+that in the meantime the \CONTEXT|/|\LUATEX\ combination gained some 25\%
+performance. Using the new Bash|-|On|-|Windows subsystem gives the same
+performance. Of course each update adds pages so in the end we need more time
+with each update but it remains a nice test case. The tight integration of \TEX,
+\METAPOST\ and \LUA\ pays off.
+
+The document style is not that complicated. The main complication in such a
+document is to make sure that \METAPOST\ is operating under the same font regime,
+but in \MKIV\ this happens automatically. As document font we use the URW
+Palatino for the running text combined with Computer Modern Typewriter. Because
+this document is available as paper and screen document, some large graphics are
+scaled down in the screen version.
+
+We don't use any special tricks in typesetting this document, but when we added
+the section about transparency, a dirty trick was needed in a few cases in order to
+get the described results. Because the screen document has gray backgrounds,
+exclusive transparencies come out \quote {wrong}. In the function drawing example
+we use the following trick to get a black background behind the graphics only. We
+have a buffer that contains a few lines of code:
+
+% buffer only available in screen mode
+
+\starttyping
+picture savedpicture ;
+savedpicture := currentpicture ;
+currentpicture := nullpicture ;
+draw savedpicture withcolor black ;
+draw savedpicture ;
+\stoptyping
+
+Since we use buffers for the graphics as well, we can now process a buffer with
+name \type {example} as follows:
+
+\starttyping
+\processbuffer[example,wipe]
+\stoptyping
+
+This means that the example code is included two times. After it is processed, we
+recolor the currentpicture black, and after that we add the original picture once
+again.

+
+\startintro
+
+Sometimes we want to go beyond \METAPOST's native features. Examples of such an
+extension are \CMYK\ colors, shading and transparency. Although features like
+this should be used with care, sometimes the documents look and feel can profit
+from it.
+
+If you don't want the whole graphic, but only a part of it, clipping comes into
+play. In addition to the standard clipping features, we can use \METAPOST\ to
+provide a decent clipping path. In this chapter we will uncover the details.
+
+We will also introduce ways to include externally defined graphics and outline
+fonts. We will demonstrate that within reasonable bounds you can manipulate such
+graphics.
+
+\stopintro
+
+\startsection[title={Spot colors}]
+
+You can define spot and multitone colors directly in \METAFUN, although normally
+you will do it at the \TEX\ end for consistency. At the \TEX\ end we define this:
+
+\startbuffer
+\definecolor [SpotBlue]   [c=1,m=.38,y=0,k=.64]
+\definecolor [SpotYellow] [c=0,m=.28,y=1,k=.06]
+\definemultitonecolor [MultiColor] [SpotBlue=.5,SpotYellow=.25]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+draw image  (
+    fill unitsquare shifted (7,0)
+        withcolor namedcolor("MultiColor") ;
+    fill unitsquare shifted (6,0)
+        withcolor .6 * spotcolor("temp1",red) ;
+    fill unitsquare shifted (5,0)
+        withcolor .4 * spotcolor("temp1",red) ;
+    fill unitsquare shifted (4,0)
+        withcolor .5 * spotcolor("temp2",.5green) ;
+    fill unitsquare shifted (3,0)
+        withcolor .5 * spotcolor("temp3",green) ;
+    fill unitsquare shifted (2,0)
+        withcolor multitonecolor("temp4",blue/2,yellow/2,green/2,magenta/3) ;
+) xsized TextWidth ;
+\stopbuffer
+
+Next we process this graphic:
+
+\typebuffer
+
+and get:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title={Transparency}]
+
+\index{transparency}
+
+{\em In the screen version we use a light gray background color. As a result,
+some of the transparency methods demonstrated here give unexpected results. The
+A4 version of this document demonstrates the real effects.}
+
+Although transparent colors have been around for some time already, it was only
+around 2000 that they made it as a high level feature into document format
+languages like \PDF. Supporting such a feature at a higher abstraction level is
+not only more portable, but also less sensitive for misinterpretation.

+You can be tempted to use transparency as a convenient way to achieve soft
+colors. In that case you should be aware of the fact that rendering transparent
+colors takes more time than normal colors \footnote {When your printer does not
+support this feature natively, the intermediate (\POSTSCRIPT) file send to the
+printing engine is also larger.}
+
+Fortunatey, \METAPOST\ provides a similar mechanism. The last circle in the
+following row demonstrates how we can trigger colors proportionally to other
+colors. Normally \type {background} is white, but you can set predefined color
+variables to another value.

+In this section we introduce different kinds of shading. Since \METAPOST\ does
+not support this feature directly, we have to fall back on a few tricks. For the
+moment shading is only supported in \PDF. In the following examples, we will use

+\stopbuffer
+
+A shade is a fill with a stepwise change in color. In \POSTSCRIPT\ (level 2), the
+way this color changes can be circular, linear, or according to a user defined
+function. Circular and linear shades look like this:

+\getbuffer[a,b,c]
+\stoplinecorrection
+
+\startlinecorrection[blank]
+\getbuffer[a,b,d]
+\stoplinecorrection
+
+As you can see, the shade lays behind the text, as a background overlay. These
+overlays are unique \METAPOST\ graphics, so they will adapt themselves to the
+dimensions of the foreground.
+
+\typebuffer[b]
+
+The two framed texts are defined as:
+
+\typebuffer[c]
+
+and:
+
+\typebuffer[d]
+
+We still have to define the graphics. Here we use a macro that takes four
+arguments: a path, a number identifying the center of shading, and the colors to
+start and end with.
+
+\typebuffer[a]
+
+The \METAPOST\ macros, \type {circular_shade} and \type {linear_shade}, add
+information to the \METAPOST\ output file, which is interpreted by the converter
+built in \CONTEXT. Shading comes down to interpolation between two or more points
+or user supplied ranges. A poor mans way of doing this, is to build the graphics
+piecewise with slightly changing colors. But, instead of \quote {manually}
+stepping through the color values, we can use the more efficient and generalized
+\POSTSCRIPT\ level~2 and \PDF\ level~1.3 shading feature.

+% % This limitation si no longer present in mpiv.
+%
+% Shading is not a \METAPOST\ feature, which means that it has to be implemented
+% using so called specials, directives that end up in the output file.
+% Unfortunately these are not coupled to the specific path, which means that we
+% have to do a significant amount of internal bookkeeping. Also, in \PDF\ we have
+% to make sure that the graphics and their resources (being the shading functions)
+% are packaged together.
+%
+% Because of this implementation, shading may behave somewhat unexpected at times.
+% A rather normal case is the next one, where we place 5~shaded circles in a row.
+%
+% \startbuffer
+% path p ; p := fullcircle scaled 1cm ;
+% for i=0 step 2cm until 8cm :

+% endfor ;
+% \stopbuffer
+%
+% \typebuffer
+%
+% \startlinecorrection[blank]
+% \processMPbuffer
+% \stoplinecorrection
+%
+% At first sight, in the next situation, we would expect something similar, because
+% we simply copy the same circle 5~times. However, due to the way we have
+% implemented shading in \CONTEXT, we do indeed copy the circles, but the shade
+% definition is frozen and the same one is used for all 5~circles. This means that
+% the center of the shading stays at the first circle.
+%
+% \startbuffer
+% circular_shade(fullcircle scaled 1cm,0,\MPcolor{a},\MPcolor{b}) ;

+%
+% Unlike \TEX, \METAPOST\ does not keep its specials attached to the current path,
+% and flushes them before the graphic data. Since we use these specials to register
+% shading information, it is rather hard to tightly connect a specific shade with a
+% certain fill, especially if an already performed fill is not accessible, which is
+% the case when we copy a picture.
+%
+% This may seem a disadvantage, but fortunately it also has its positive side. In
+% the next example we don't copy, but reuse an already defined shade. By storing
+% the reference to this shade, and referring to it by using \type {withshade}, we
+% can use a shade that operates on multiple shapes.

+The low level macro \type {define_circular_shade} is fed with two pairs (points),
+two radius, and two colors. The shade is distributed between the colors according
+to the radius.
+
+Shading can hardly be called an easy issue. The macros that we provide here are
+in fact simplifications, which means that at a lower level, one can do more
+advanced things. Here we limit ourselves to the more common cases. In the
+previous examples, we used an arrow to indicate the direction and magnitude of
+the shade. The next macro demonstrates the principles in a different way.

+By now the shader macros are rather advanced and specifications are easier than

+There are several properties that can be set:
+
+\starttabulate[|l|p|]
+\NC domain  \NC The range over which the colors run, with a minimum of 0 and maximum of 1. \NC \NR
+\NC color   \NC A color to start from and one to end with, we default from black to white. \NC \NR
+\NC type    \NC The shading can be linear or circular. \NC \NR
+\NC center  \NC The origin of the shade vector. \NC \NR
+\NC radius  \NC The radius vector of a circular shade. \NC \NR
+\NC vector  \NC Where we start and end the shading. \NC \NR
+\stoptabulate
+
+For a linear shade the centers are the lower left and upper right corners, for a
+circular shade it's the center of the path. For a circular shade the radius runs
+from zero to the maximum distance from the center as determined by the
+boundingbox.
+
+The vector is used as follows: the first coordinate (xpart) determines the point
+on the path where we start, the second coordinate (ypart) the point on the
+path where we end.
+
+\startbuffer[a]

+So, where a vector is defined as going from {\em point xpart a of pth} to
+{\em point ypart a of pth}, a direction goes from {\em point xpart a of
+boundingbox pth} to {\em point ypart a of boundingbox pth}.
+
+To make life convenient we provide a few constants that indicate directions:
+
+\starttyping
+pair shadedup    ; shadedup    := (0.5,2.5) ;
+pair shadeddown  ; shadeddown  := (2.5,0.5) ;
+pair shadedleft  ; shadedleft  := (1.5,3.5) ;
+pair shadedright ; shadedright := (3.5,1.5) ;
+\stoptyping

+
+In case of a circular shade another method comes in handy:
+
+\startbuffer[a]
+fill fullcircle xyscaled (TextWidth,4cm)
+    withshademethod "circular"
+    withshadecenter (.7,.9)
+    withshadecolors (darkblue,darkyellow)
+;
+\stopbuffer
+
+\startbuffer[b]
+draw fullcircle xyscaled (TextWidth,4cm)
+    shownshadecenter (.7,.9)
+    withpen pencircle scaled 2
+    withcolor .5white ;
+\stopbuffer
+
+\typebuffer
+
+Here the values relate to the center of path i.e.\ they shift the center by the
+given fraction of the width and height of the boundingbox devided by 2.
+
+\startlinecorrection[blank]
+    \processMPbuffer[a,b]
+\stoplinecorrection
+
+You can set a center directly i.e.\ unrelated to the center of the path as
+follows:
+
+\startbuffer[a]
+fill fullcircle xyscaled (TextWidth,4cm)
+    withshademethod "circular"
+    withshadeorigin (-30mm,-15mm)
+    withshadecolors (darkblue,darkyellow)
+;
+\stopbuffer
+
+\startbuffer[b]
+draw fullcircle xyscaled (TextWidth,4cm)
+    shownshadeorigin (-30mm,-15mm)
+    withpen pencircle scaled 2
+    withcolor .5white ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer[a,b]
+\stoplinecorrection
+
+In a similar way you can set an explicit radius:
+
+\startbuffer[a]
+fill fullcircle xyscaled (TextWidth,1cm)
+    withshademethod "circular"
+    withshaderadius (10mm,50mm)
+    withshadecolors (darkblue,darkyellow)
+;
+currentpicture := currentpicture shifted (0,15mm) ;
+fill fullcircle xyscaled (TextWidth,1cm)
+    withshademethod "circular"
+    withshaderadius (50mm,10mm)
+    withshadecolors (darkgreen,darkred)
+;
+currentpicture := currentpicture shifted (0,15mm) ;
+fill fullcircle xyscaled (TextWidth,1cm)
+    withshademethod "circular"
+    withshaderadius (TextWidth/3,0mm)
+    withshadecolors (darkmagenta,darkcyan)
+;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer[a]
+\stoplinecorrection
+
+A more fancy feature is combined shades. This works as follows:
+
+\startbuffer[a]
+fill fullsquare xyscaled (TextWidth,1cm)
+    withshademethod "linear"
+    withshadevector (0,1)
+    withshadestep (
+        withshadefraction .3
+        withshadecolors (red,green)
+    )
+    withshadestep (
+        withshadefraction .5
+        withshadecolors (green,blue)
+    )
+    withshadestep (
+        withshadefraction .7
+        withshadecolors (blue,red)
+    )
+    withshadestep (
+        withshadefraction 1
+        withshadecolors (red,yellow)
+    )
+;
+\stopbuffer
+
+\typebuffer[a]
+
+By stepwise defining the colored bands you get:
+
+\startlinecorrection[blank]
+    \processMPbuffer[a]

+
+Shades work well with colors and transparencies. This involves quite some
+resource managament in the backend but it's hidden by the interface.

+
+\index{clipping}
+
+In this section we will use the graphic representation (although simplified) of a
+Dutch cow to demonstrate clipping.
+
+\startbuffer
+\placefigure
+  {A cow.}
+  {\externalfigure[cow-fun.mps][width=4cm]}
+\stopbuffer
+
+\getbuffer
+
+Since this cow is defined as a \METAPOST\ graphic, we use the suffix \type {mps}
+instead of \type {eps} or a number, although \CONTEXT\ will recognize each as
+being \METAPOST\ output. The placement of the cow is defined as:
+
+\typebuffer
+
+Clipping is combined with a matrix, as in \in {figure} [fig:clipped cow 1]. The
+content to be clipped is divided in \type {nx} by \type {ny} rectangles. For
+instance, \type {nx=5} and \type {ny=8} will produce a 40~cell grid with
+5~columns of 8~rows.
+
+\startbuffer
+\startbuffer
+\setupclipping[nx=3,ny=2]
+\startcombination
+  {\clip[x=1,y=1]{\externalfigure[cow-fun.mps][width=4cm]}} {1,1}
+  {\clip[x=3,y=1]{\externalfigure[cow-fun.mps][width=4cm]}} {3,1}
+\stopcombination
+\stopbuffer
+
+\placefigure
+  [here][fig:clipped cow 1]
+  {A clipped cow.}{\getbuffer}
+\stopbuffer
+
+\getbuffer
+
+Here we have divided the cow in six cells, so that we can clip its head and tail.
+This kind of clipping enables you to zoom in or focus on a specific part of a
+graphic.
+
+\typebuffer
+
+Alternatively, we can specify a \type {width}, \type {height}, \type {hoffset}
+and \type {voffset}, as demonstrated in \in {figure} [fig:clipped cow 2].
+
+\startbuffer
+\placefigure
+  [here][fig:clipped cow 2]
+  {Another clipped cow.}
+  {\clip
+     [width=2cm,height=2cm,hoffset=0cm,voffset=0cm]
+     {\externalfigure[cow-fun.mps][width=4cm]}}
+\stopbuffer
+
+\getbuffer
+
+\typebuffer
+
+Because \METAPOST\ supports clipping, it will be no surprise that both techniques
+can be combined. In the next example we will zoom in on the head of the cow. We
+also use this opportunity to demonstrate how you can package a clip in a figure
+definition.
+
+\startbuffer
+\startMPclip{head clip}
+ w := \width ; h := \height ;
+ clip currentpicture to
+  ((0,h)--(w,h){down}..{left}(0,0)--cycle) ;
+\stopMPclip
+
+\placefigure
+  [here][fig:circular clipped cowhead]
+  {A quarter circle applied to a cows head.}
+  {\ruledhbox
+     {\clip
+        [nx=2,ny=2,x=1,y=1,mp=head clip]
+        {\externalfigure[cow-fun.mps][width=4cm]}}}
+\stopbuffer
+
+\typebuffer
+
+A more advanced clip is demonstrated in \in {figure} [fig:circular clipped
+cowhead]. We added \type {\ruledhbox} to demonstrate the dimensions of the
+resulting graphic. Putting something in such a ruled box is often a quick way to
+test spacing.
+
+\getbuffer
+
+Although a clip path definition can contain any \METAPOST\ command, even
+graphics, it must contain at least one clipping path. The first one encountered
+in the resulting graphic is used. In the example we used a path that is built out
+of three subpaths.
+
+\starttyping
+(0,h)--(w,h){down}..{left}(0,0)--cycle
+\stoptyping
+
+We start in the top left corner and draw a straight line. Next we draw a curve to
+the origin. Directives like \type {down} and \type {right} force the curve in a
+certain direction. With \type {cycle} we close the path. Because we use this path
+as a clipping path, we use \type {clip} instead of \type {draw} or \type {fill}.
+
+\startbuffer
+w := 4cm ; h := 2cm ;
+draw (0,h)--(w,h){down}..{left}(0,0)--cycle
+  withpen pencircle scaled 1mm withcolor .625red ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Clipping as such is not limited to graphics. Take for instance the text buffer:
+
+\startbuffer
+\startbuffer[sample]
+\framed
+  [align=middle,width=4cm,background=screen,frame=off]
+  {A \METAPOST\ clip is not the same as a video clip,
+   although we can use \METAPOST\ to produce a video clip.}
+\stopbuffer
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We can call up such a buffer as if it were an external figure. \in {Figure}
+[fig:clipped text 1] shows the result. This time we use a different clip path:
+
+\startbuffer[a]
+\startMPclip{text clip}
+  clip currentpicture to fullcircle shifted (.5,.5)
+    xscaled \width yscaled \height ;
+\stopMPclip
+\stopbuffer
+
+\typebuffer[a]
+
+To load a buffer, we have to specify its name and type, as in:
+
+\startbuffer[b]
+\placefigure
+  [here][fig:clipped text 1]
+  {A clipped buffer (text).}
+  {\clip
+     [nx=1,ny=1,mp=text clip]
+     {\externalfigure[sample][type=buffer,width=4cm]}}
+\stopbuffer
+
+\typebuffer[b]
+
+\getbuffer[a,b]
+
+The next few lines demonstrate that we can combine techniques like backgrounds
+and clipping.
+
+\startbuffer
+\startuseMPgraphic{clip outline}
+ draw fullcircle
+   xscaled \overlaywidth yscaled \overlayheight
+   withpen pencircle scaled 4mm
+   withcolor .625red ;
+\stopuseMPgraphic
+
+\defineoverlay[clip outline][\useMPgraphic{clip outline}]
+
+\placefigure
+  [here][fig:clipped text 2]
+  {A clipped buffer (text).}
+  {\framed
+     [background=clip outline,offset=overlay,frame=off]
+     {\clip
+        [nx=1,ny=1,mp=text clip]
+        {\externalfigure[sample][type=buffer,width=4cm]}}}
+\stopbuffer
+
+\typebuffer
+
+We could have avoided the \type {\framed} here, by using the \typ{clip outline}
+overlay as a background of the sample. In that case, the resulting linewidth
+would have been 2.5~mm instead of 5~mm, since the clipping path goes through the
+center of the line.
+
+\getbuffer
+
+In most cases, the clip path will be a rather simple path and defining such a
+path every time you need it, can be annoying. \in {Figure} [fig:clipping paths]
+shows a collection of predefined clipping paths. These are available after
+loading the \METAPOST\ clipping library.
+
+\starttyping
+\useMPlibrary[clp]
+\stoptyping
+
+We already saw how the circular clipping path was defined. The diamond is defined
+in a similar way, using the predefined path \type {diamond}:
+
+\starttyping
+\startMPclip{diamond}
+  clip currentpicture to unitdiamond
+    xscaled \width yscaled \height ;
+\stopMPclip
+\stoptyping
+
+The definition of the negated ellipse (\type {negellipse}) uses the primary \type
+{peepholed}. This primary is defined in one of the \METAPOST\ modules that come
+with \CONTEXT.
+
+\starttyping
+\startMPclip{negellipse}
+  clip currentpicture to (unitcircle peepholed unitsquare)
+    xscaled \width yscaled \height ;
+\stopMPclip
+\stoptyping
+
+The definition of \type {peepholed} is rather dirty and using \type {peepholed}
+is restricted to well defined situations (like here). It's called a primary
+because it acts as an operator at the same level as \type {*} and \type {scaled}.

+\index{graphics+including}
+
+This document demonstrates that it is no big problem to include \METAPOST\
+graphics in a \TEX\ document. But how about including graphics in a \METAPOST\
+picture? In this section we will explore a couple of macros that provide you this
+feature.
+
+Before we go into details, we introduce a very impressive program called
+\PSTOEDIT\ by Wolfgang Glunz. This program runs on top of \GHOSTSCRIPT\ and is
+able to convert \POSTSCRIPT\ code into other formats, among them \METAPOST\ (that
+part of the \PSTOEDIT\ code is due to Scott Pakin). Some of the graphics that we
+use in this section are produced that way. For us, the next call works well, but
+the exact call may differ per version or platform.
+
+\starttyping
+pstoedit -ssp -dt -f mpost yourfile.ps newfile.mp
+\stoptyping
+
+We have converted the Dutch cow that shows up in many \CONTEXT\ documents into
+\METAPOST\ using this program. The resulting \METAPOST\ file encapsulates the cow
+in \METAPOST\ figure~1: \type {beginfig(1)}. Of course you can process this file
+like any other, but more interesting is to use this code in an indirect way.
+
+\startbuffer
+loadfigure "mycow.mp" number 1 scaled .5 ;
+\stopbuffer
+
+\typebuffer
+
+This call will load figure~1 from the specified \METAPOST\ file, in such a way
+that there is no interference with the current (encapsulating) figure.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Because this graphic is the result from a conversion, there are only paths. If
+you want to import a more complex graphic, you need to make sure that the
+variables used in there do not conflict with the one currently in use.
+
+\METAPOST\ is good in drawing vector graphics, but lacks natural support for
+bitmaps, but the next macro offers a way out. This macro permits you to include
+graphics in \PNG, \PDF, and \JPG\ format, or more precise: those formats
+supported by \PDFTEX.\pagereference[hacker]
+
+\startbuffer
+draw externalfigure "hacker.png" scaled 5cm shifted (-6cm,0) ;
+draw externalfigure "hacker.png" scaled 5cm slanted .5 ;
+\stopbuffer
+
+\typebuffer
+
+You can apply the usual transformations, but only those applied directly will be
+taken into account. This means that you (currently) cannot store external figures
+in picture variables in order to transform them afterwards.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Although you are limited in what you can do with such graphics, you can include
+them multiple times with a minimum of overhead. Graphics are stored in objects
+and embedded only once.

+  draw externalfigure "hacker.png"
+    scaled s rotatedaround (c,0 randomized 30) shifted d ;
+endfor ;
+\stopbuffer
+
+\typebuffer
+
+Because we cannot store the graphic in a picture and scale afterwards, we
+calculate the scale in advance, so that we can rotate around the center.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+As long as you don't mess around with a stored external figure, you're safe. The
+following example demonstrates how we can combine two special driven features:
+figure inclusion and shading.

+p := externalfigure "hacker.png" scaled 150pt ;

+We end this section with a few more words to \METAPOST\ inclusion. It may seem
+that in order to use the features discussed here, you need to use \CONTEXT\ as
+typesetting engine. This is not true. First of all, you can use the small \TEX\
+package \MPTOPDF\ (described in another manual) or you can make small \CONTEXT\
+files with one page graphics. The advantage of the last method is that you can
+manipulate graphics a bit.

+One of the advantages of \METAPOST\ graphics is that it is rather easy to force
+consistency in colors and line widths. You seldom can influence third party
+graphics that way, but we can use some \METAFUN\ trickery to get around this
+limitation.

+Including another \METAPOST\ graphic, refilling, redrawing, and recoloring are
+all relatively simple features that use no real tricks. Opposite to the next
+feature, which is implemented using the \METAPOST\ special driver that comes with
+\CONTEXT.
+
+\METAPOST\ is not really meant for manipulating graphics, but the previous
+examples demonstrated that we have some control over individual colors. In the
+next series of examples we will treat the picture as a whole. First we invert the
+colors using \type {inverted}.
+
+\startbuffer
+loadfigure "gracht.mp" number 1 scaled .5 ;

+  shifted (bbwidth(currentpicture)+.5cm,0) ;

+  (currentpicture uncolored green)
+  shifted (bbwidth(currentpicture)+.5cm,0) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+You can also multiply each color using \type {softened}. In the next sample, the
+colors have 80\% of their value.
+
+\startbuffer
+loadfigure "gracht.mp" number 1 scaled .5 ;
+addto currentpicture also
+  (currentpicture softened .8)
+  shifted (bbwidth(currentpicture)+.5cm,0) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+You can also use this operator to harden colors, simply by
+providing a value larger than~1. Keep in mind that colors
+are clipped at~1 anyway.
+
+\startbuffer
+loadfigure "gracht.mp" number 1 scaled .5 ;
+addto currentpicture also

+  shifted (bbwidth(currentpicture)+.5cm,0) ;

+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection

+%
+% Outline fonts don't belong to \METAPOST's repertoire of features. Nevertheless we
+% can simulate this in a reasonable way. We will not discuss all details here,
+% because most details are covered in the \MAKEMPY\ manual.
+%
+% The macro responsible for outline fonts is \type {graphictext}. The first
+% argument should be a string. This string is processed by \TEX. Additionally you
+% can provide transformation directives and color specifications. The next example
+% demonstrates this.
+%
+% \startbuffer
+% graphictext "\bf Fun" scaled 4 zscaled (1,1.5)
+%   withdrawcolor blue
+%   withfillcolor .5white
+%   withpen pencircle scaled 5pt
+% \stopbuffer
+%
+% \typebuffer
+%
+% Once the text is typeset by \TEX, it is converted to \POSTSCRIPT\ and converted
+% into \METAPOST\ by the \PSTOEDIT\ program. The resulting graphic is imported,
+% analyzed, and processed conforming the specifications of \type {graphictext}.
+%
+% \startlinecorrection[blank]
+% \processMPbuffer
+% \stoplinecorrection
+%
+% By default the shapes are filled after they are drawn. This has the advantage
+% that in characters built out of pieces, disturbing lines fragments are covered.
+% The drawback is that you get only half the linewidth. You can reverse the drawing
+% order by adding the \type {reversefill} directive. The previous graphic then
+% comes out as:
+%
+% \startbuffer
+% graphictext "\bf Fun" scaled 4 zscaled (1,1.5)
+%   reversefill
+%   withdrawcolor blue
+%   withfillcolor .5white
+%   withpen pencircle scaled 5pt
+% \stopbuffer
+%
+% \typebuffer
+%
+% The \type {reversefill} directive can be countered by \type {outlinefill}.

+
+Outline fonts don't belong to \METAPOST's repertoire of features. Nevertheless we
+can simulate this in a reasonable way. The current version of \METAFUN\ uses the
+outline subsystem of \CONTEXT\ \MKIV, but in earlier days we used an external
+process: a \PDF\ file is generated that has the snippet, that gets converted to
+\POSTSCRIPT, which in turn is converted to \METAPOST\ with \type {pstoedit} and
+from that result we filter the outlines. This method uses \type {graphictext} and
+is covered in the \MAKEMPY\ manual. Here we discuss the new method using \type
+{outlinetext}.

+
+The following feature is not that usefull but implemented anyway. The \PDF\ reference says:
+
+\startitemize
+    \startitem
+        A group may be isolated or non-isolated, which shall determine the
+        initial backdrop against which its stack is composited.
+    \stopitem
+    \startitem
+        A group may be knockout or non-knockout, which shall determine whether
+        the objects within its stack are composited with one another or only with
+        the group’s backdrop.
+    \stopitem
+\stopitemize
+
+and then carries on with a detailed explanation of groups. Here we stick to just
+mentioning how one can create a group in a picture. First we define a helper:
+
+\startbuffer
+\startMPdefinitions
+    def ShowGroup (expr clr) (text grouped) =
+        draw image (
+            drawarrow (10,0) -- (0,0)
+                withtransparency(1,.5)
+                withcolor clr ;
+        ) grouped ;
+        currentpicture := currentpicture xsized (TextWidth/8) ;
+        setbounds currentpicture to boundingbox currentpicture enlarged 2mm ;
+        addbackground withcolor .5white ;
+    enddef ;
+\stopMPdefinitions

+        {\startMPcode ShowGroup(.5green)  (asgroup "")                  \stopMPcode} {\tttf group}

+        {\startMPcode ShowGroup(.5cyan)   (asgroup "knockout")          \stopMPcode} {\tttf knockout}
+        {\startMPcode ShowGroup(.5magenta)(asgroup "isolated,knockout") \stopMPcode} {\tttf isolated\crlf knockout}
+    \stopcombination
+\stoplinecorrection
+
+The syntax is:
+
+\starttyping
+draw somepicture|somepath grouped "[isolated|knockout] ;
+\stoptyping
+
+The group becomes an object and is no longer part of the stream of graphic
+operators but a reference. For what it's worth: I never needed this feature.
+
+\stopsection
+
+\startsection[title=Decorating]
+
+Although the \METAPOST\ language is quite powerful the number of data types is
+not that large and when it comes to drawing stuff there are only paths and
+pictures. A path is a list of points (with controlpoints) and a few properties,
+like the pen, linewidth, linecap, color and such. For a long time in \METAFUN\ we
+used so called specials to implement extensions (like shading). This was done by
+using special colors and associating these with entries in the special section at
+the top of the output.
+
+Nowadays we use the pre- and postscript properties of paths. The advantage is
+that we can add whatever we want, as long as the backend supports it and because
+the backend is written in \LUA\ there are no real limitations. So, instead of
+extending \METAPOST\ we extend the \METAFUN\ macros and backend.
+
+Most extensions use the prescripts. Think of this:
+
+\starttyping
+draw fullcircle
+    withprescript "do this"
+    withprescript "and that"
+    withprescript "and even more" ;
+\stoptyping
+
+Eventually this becomes a string:
+
+\starttyping
+and even more<newline>and that<newline>do this
+\stoptyping
+
+\typebuffer
+
+The prescripts get prepended, while the postscripts (that we use for text only)
+get appended. When we draw a picture with properties (like color) they get
+overwritten but not so (with good reason) for the pre- and postscripts: these
+just accumulate. We will now demonstrate how we can manipulate the picture
+(a bit).
+
+\startbuffer
+picture MyShape ; MyShape := image (
+    fill fullsquare xyscaled (4,1) withcolor .625red ;
+    fill fullsquare xyscaled (3,1) withcolor .625green ;
+    fill fullsquare xyscaled (2,1) withcolor .625blue ;
+    fill fullsquare xyscaled (1,1) withcolor .625yellow ;
+) xysized (TextWidth,1cm) ;
+
+draw MyShape;
+\stopbuffer
+
+\typebuffer
+
+We just draw the (natural) picture:
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+When we draw the picture with a new color, all its components get recolored:
+
+\startbuffer
+draw MyShape
+    withcolor .625magenta ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+However, when we add a transparency only the first component gets adapted because
+we use prescripts for this extension. (An extension using the postscripts would
+affect the last component.)
+
+\startbuffer
+draw MyShape
+    withcolor .625magenta
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+The same logic applied to the \type {image}: prescripts get prepended to the
+first copmponent, postscripts to the last.
+
+\startbuffer
+draw image (draw MyShape)
+    withcolor .625cyan ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+\startbuffer
+draw image (draw MyShape)
+    withcolor .625cyan
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+The \type {undecorated} macro ignores the properties. We can't reset the scripts as
+this could ruin the effects like shading.
+
+\startbuffer
+draw undecorated (draw MyShape)
+    withcolor .625white ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+The \type {decorated} macro applies the properties to each component.
+
+\startbuffer
+draw decorated (draw MyShape)
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+Here we kept the colors as they are but next we redo them:
+
+\startbuffer
+draw decorated (draw MyShape)
+    withcolor .625magenta
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+The \type {redecorated} macro is the most intrusive as it resets the properties.
+This also means that you will loose texts, shades etc.
+
+\startbuffer
+draw redecorated (draw MyShape)
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+Indeed we get no color (but black) but we can bring back some color:
+
+\startbuffer
+draw redecorated (draw MyShape)
+    withcolor .625yellow
+    withtransparency (1,.5) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \processMPbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title=Properties]
+
+The (plain) \METAPOST\ macro \type {drawoptions} stored its arguments
+in a macro that gets expanded when something is drawn (or filled). So, when you say
+
+\starttyping
+drawoptions(withcolor red) ;
+draw somepath ;
+\stoptyping
+
+This effectively is:
+
+\starttyping
+draw somepath withcolor red ;
+\stoptyping
+
+A disadvantage is that there is not much control over where it gets applied,
+especially when you hide drawing operations in macros. It's the reason why
+personally I always prefer explicit options. If you want some abstraction
+you can use the properties feature:
+
+\startbuffer
+\startMPcode
+    property p[] ;
+    p1 = properties(withcolor "darkred") ;
+    p2 = properties(withcolor "darkblue") ;
+    p3 = properties(withcolor "darkgreen") ;
+    fill fullsquare xysized (TextWidth,12mm) withproperties p1 ;
+    fill fullsquare xysized (TextWidth, 8mm) withproperties p2 ;
+    fill fullsquare xysized (TextWidth, 4mm) withproperties p3 ;
+    fill fullsquare xysized (TextWidth, 2mm) withproperties p1 ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+We get:
+
+\startlinecorrection
+\getbuffer
+\stoplinecorrection
+
+Here we use an \quote {array} of properties but a single property is also possible:
+
+\startbuffer
+\startMPcode
+    property p ;
+    p = properties(withcolor "darkyellow") ;
+    fill fullsquare xysized (TextWidth,4mm) withproperties p ;
+\stopMPcode
+\stopbuffer
+

+\startchapter[reference=sec:embedding,title={Embedded graphics}]
+
+\startintro
+
+In addition to the \type {beginfig}||\type {endfig} method, there are other ways
+to define and include a \METAPOST\ graphic. Each method has its advantages and
+disadvantages.
+
+In the previous chapter we were still assuming that the graphic was defined in
+its own file. In this chapter we will introduce the interface between \CONTEXT\
+and \METAPOST\ and demonstrate how the definitions of the graphics can be
+embedded in the document source.
+
+\stopintro
+
+\startsection[title={Getting started}]
+
+\index{running}
+\index{processing}
+
+From now on, we will assume that you have \CONTEXT\ running on your platform.
+Since \PDF\ has full graphics support, we also assume that you use \LUATEX\ in
+combination with \CONTEXT\ \MKIV, although most will also work with other engines
+and \MKII. Since this document is not meant as a \CONTEXT\ tutorial, we will
+limit this introduction to the basics needed to run the examples.
+
+A simple document looks like:
+
+\starttyping
+\starttext
+  Some text.
+\stoptext
+\stoptyping
+
+You can process this document with the \LUA\ based command line interface to
+\CONTEXT. If the source code is embedded in the file \type {mytext.tex}, you can
+say:
+
+\starttyping
+context mytext
+\stoptyping
+
+We will use color, and in \MKIV\ color is enabled by default. If you don't want
+color you can tell \CONTEXT, so
+
+\starttyping
+\setupcolors[state=stop]
+\starttext
+  Some \color[blue]{text} and/or \color[green]{graphics}.
+\stoptext
+\stoptyping
+
+comes out in black and white.
+
+In later chapters we will occasionally see some more \CONTEXT\ commands show up.
+If you want to know more about what \CONTEXT\ can do for you, we recommend the
+beginners manual and the reference manual, as well as the wiki pages.
+
+\stopsection
+
+\startsection[title={External graphics}]
+
+\index {graphics+external}
+
+Since \TEX\ has no graphic capabilities built in, a graphic is referred to as an
+external figure. A \METAPOST\ graphic often has a number as suffix, so embedding
+such a graphic is done by:
+
+\starttyping
+\externalfigure[graphic.123][width=4cm]
+\stoptyping
+
+An alternative method is to separate the definition from the inclusion. An
+example of a definition is:
+
+\starttyping
+\useexternalfigure[pentastar][star.803][height=4cm]
+\useexternalfigure[octostar] [star.804][pentastar]
+\stoptyping
+
+Here, the second definition inherits the characteristics from the first one.
+These graphics can be summoned like:
+
+\starttyping
+\placefigure
+  {A five||point star drawn by \METAPOST.}
+  {\externalfigure[pentastar]}
+\stoptyping
+
+Here the stars are defined as stand||alone graphics, in a file called \type
+{star.mp}. Such a file can look like:
+
+\starttyping
+def star (expr size, n, pos) =
+  for a=0 step 360/n until round(360*(1-1/n)) :
+    draw (origin -- (size/2,0))
+      rotatedaround (origin,a) shifted pos ;
+  endfor ;
+enddef ;
+
+beginfig(803) ;
+  pickup pencircle scaled 2mm ; star(2cm,5,origin) ;
+endfig ;
+
+beginfig(804) ;
+  pickup pencircle scaled 1mm ; star(1cm,8,origin) ;
+  pickup pencircle scaled 2mm ; star(2cm,7,(3cm,0)) ;
+endfig ;
+
+end.
+\stoptyping
+
+This \type {star} macro will produce graphics like:
+
+\startbuffer
+def star (expr size, n, pos) =
+  for a=0 step 360/n until round(360*(1-1/n)) :
+    draw (origin -- (size/2,0))
+      rotatedaround (origin,a) shifted pos ;
+  endfor ;
+enddef ;
+
+for i=5 upto 10 :
+  drawoptions (withpen pencircle scaled 2mm withcolor .625red) ;
+  star(1cm,i,origin shifted (i*2cm,0)) ;
+endfor ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+But, now that we have instant \METAPOST\ available in \LUATEX, there is no need
+for external images and we can collect them in libraries, as we will see later
+on.
+
+\stopsection
+
+\startsection[title={Integrated graphics}]
+
+\index{graphics+embedded}
+
+An integrated graphic is defined in the document source or in a style definition
+file. The most primitive way of doing this is just inserting the code:
+
+\starttyping
+\startMPcode
+  fill fullcircle scaled 200pt withcolor .625white ;
+\stopMPcode
+\stoptyping
+
+Such a graphic is used once at the spot where it is defined. In this document we
+also generate graphics while we finish a page, so there is a good chance that
+when we have constructed a graphic which will be called on the next page, the
+wrong graphic is placed.
+
+For this reason there are are more convenient ways of defining and using
+graphics, which have the added advantage that you can predefine multiple
+graphics, thereby separating the definitions from the usage.
+
+The first alternative is a {\em usable} graphic. Such a graphic is calculated
+anew each time it is used. An example of a usable graphic is:
+
+\starttyping
+\startuseMPgraphic{name}
+  fill fullcircle scaled 200pt withcolor .625yellow ;
+\stopuseMPgraphic
+\stoptyping
+
+When you put this definition in the preamble of your document, you can place this
+graphic anywhere in the file, saying:
+
+\starttyping
+\useMPgraphic{name}
+\stoptyping
+
+As said, this graphic is calculated each time it is placed, which can be time
+consuming. Apart from the time aspect, this also means that the graphic itself is
+incorporated many times. Therefore, for graphics that don't change, \CONTEXT\
+provides {\em reusable} graphics:
+
+\starttyping
+\startreusableMPgraphic{name}
+  fill fullcircle scaled 200pt withcolor .625yellow;
+\stopreusableMPgraphic
+\stoptyping
+
+This definition is accompanied by:
+
+\starttyping
+\reuseMPgraphic{name}
+\stoptyping
+
+Imagine that we use a graphic as a background for a button. We can create a
+unique and reusable graphic by saying:
+
+\starttyping
+\def\MyGraphic
+  {\startreusableMPgraphic{name:\overlaywidth:\overlayheight}
+      path p ; p := unitsquare
+        xscaled OverlayWidth yscaled OverlayHeight ;
+      fill p withcolor .625yellow ;
+      draw p withcolor .625red ;
+   \stopreusableMPgraphic
+   \reuseMPgraphic{name:\overlaywidth:\overlayheight}}
+\stoptyping
+
+Notice the use of \type {OverlayWidth} and \type {OverlayHeight}. These variables
+are set for each call to \METAPOST. After this we can say:
+
+\starttyping
+\defineoverlay[my graphic][\MyGraphic]
+\button[background=my graphic,frame=off]{Go Home}[firstpage]
+\stoptyping
+
+Say that we have a 30pt by 20pt button, then the identifier will be \type
+{name:30pt:20pt}. Different dimensions will lead to other identifiers, so this
+sort of makes the graphics unique.
+
+We can bypass the ugly looking \type {\def} by using a third class of embedded
+graphics, the {\em unique} graphics.
+
+\starttyping
+\startuniqueMPgraphic{name}
+  path p ; p := unitsquare
+    xscaled OverlayWidth yscaled OverlayHeight ;
+  fill p withcolor .625yellow ;
+  draw p withcolor .625red ;
+\stopuniqueMPgraphic
+\stoptyping
+
+Now we can say:
+
+\starttyping
+\defineoverlay[my graphic][\uniqueMPgraphic{name}]
+\button[background=my graphic,frame=off]{Go Home}[firstpage]
+\stoptyping
+
+A shorter variant is:
+
+\starttyping
+\startuniqueMPgraphic{name}
+  fill OverlayBox withcolor .625yellow ;
+  draw OverlayBox withcolor .625red ;
+\stopuniqueMPgraphic
+\stoptyping
+
+You may wonder why unique graphics are needed when a single graphic might be used
+multiple times by scaling it to fit the situation. Since a unique graphic is
+calculated for each distinctive case, we can be sure that the current
+circumstances are taken into account. Also, scaling would result in incomparable
+graphics. Consider the following definition:
+
+\startbuffer[a]
+\startuseMPgraphic{demo}
+  draw unitsquare
+    xscaled 5cm yscaled 1cm
+    withpen pencircle scaled 2mm
+    withcolor .625red ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer[a]
+
+Since we reuse the graphic, the dimensions are sort of fixed, and because the
+graphic is calculated once, scaling it will result in incompatible line widths.
+
+\startbuffer[b]
+\hbox \bgroup
+  \scale[width=5cm,height=1cm]{\useMPgraphic{demo}}\quad
+  \scale[width=8cm,height=1cm]{\useMPgraphic{demo}}%
+\egroup
+\stopbuffer
+
+\startlinecorrection[blank]
+\getbuffer[a,b]
+\stoplinecorrection
+
+These graphics were placed with:
+
+\typebuffer[b]
+
+Imagine what happens when we add some buttons to an interactive document without
+taking care of this side effect. All the frames would look different. Consider
+the following example.
+
+\startbuffer[a]
+\startuniqueMPgraphic{right or wrong}
+  pickup pencircle scaled .075 ;
+  fill unitsquare withcolor .8white ;
+  draw unitsquare withcolor .625red ;
+  currentpicture := currentpicture
+    xscaled OverlayWidth yscaled OverlayHeight ;
+\stopuniqueMPgraphic
+\stopbuffer
+
+\typebuffer[a]
+
+Let's define this graphic as a background to some buttons.
+
+\startbuffer[b]
+\defineoverlay[button][\uniqueMPgraphic{right or wrong}]
+\setupbuttons[background=button,frame=off]
+\stopbuffer
+
+\startbuffer[c]
+\hbox
+  {\button {previous}          [previouspage]\quad
+   \button {next}              [nextpage]\quad
+   \button {index}             [index]\quad
+   \button {table of contents} [content]}
+\stopbuffer
+
+\typebuffer[b,c]
+
+The buttons will look like:
+
+\startlinecorrection[blank]
+\setupinteraction[state=start,color=,contrastcolor=]
+\getbuffer[a,b,c]
+\stoplinecorrection
+
+Compare these with:
+
+\startbuffer[a]
+\startuniqueMPgraphic{wrong or right}
+  pickup pencircle scaled 3pt ;
+  path p ; p := unitsquare
+    xscaled OverlayWidth yscaled OverlayHeight ;
+  fill p withcolor .8white ;
+  draw p withcolor .625red ;
+\stopuniqueMPgraphic
+\stopbuffer
+
+\startlinecorrection[blank]
+\getbuffer[a,b]
+\defineoverlay[button][\uniqueMPgraphic{wrong or right}]
+\setupinteraction[state=start,color=,contrastcolor=]
+\getbuffer[c]
+\stoplinecorrection
+
+Here the graphic was defined as:
+
+\typebuffer[a]
+
+The last class of embedded graphics are the {\em runtime} graphics. When a
+company logo is defined in a separate file \type {mylogos.mp}, you can run this
+file by saying:
+
+\starttyping
+\startMPrun
+  input mylogos ;
+\stopMPrun
+\stoptyping
+
+The source for the logo is stored in a file named \type {mylogos.mp}.
+
+\startbuffer
+beginfig(21) ;
+  draw fullsquare            withcolor .625red ;
+  draw fullsquare rotated 45 withcolor .625red ;
+  picture cp ; cp := currentpicture ;
+  def copy = addto currentpicture also cp enddef ;
+  copy scaled .9 withcolor .625white  ;
+  copy scaled .7 withcolor .625yellow ;
+  copy scaled .6 withcolor .625white  ;
+  copy scaled .4 withcolor .625red    ;
+  copy scaled .3 withcolor .625white  ;
+  fill fullcircle scaled .2 withcolor .625yellow ;
+  currentpicture := currentpicture scaled 50 ;
+endfig ;
+end .
+\stopbuffer
+
+\typebuffer
+
+In this example the result is available in the virtual file \type {mprun.21}.
+This file can be included in the normal way, using:
+
+\starttyping
+\externalfigure[mprun.21][width=5cm]
+\stoptyping
+
+\startuseMPgraphic{dummy logo}
+  draw fullsquare            withcolor .625red ;
+  draw fullsquare rotated 45 withcolor .625red ;
+  picture cp ; cp := currentpicture ;
+  def copy = addto currentpicture also cp enddef ;
+  copy scaled .9 withcolor .625white  ;
+  copy scaled .7 withcolor .625yellow ;
+  copy scaled .6 withcolor .625white  ;
+  copy scaled .4 withcolor .625red    ;
+  copy scaled .3 withcolor .625white  ;
+  fill fullcircle scaled .2 withcolor .625yellow ;
+  currentpicture := currentpicture scaled 3cm ;
+\stopuseMPgraphic
+
+\placefigure
+  {The logo is defined in the file \type {mylogos.mp} as
+   figure~21 and processed by means of the \type {mprun}
+   method.}
+  {\useMPgraphic{dummy logo}}
+
+Optionally you can specify a name and an instance. This has the advantage that
+the graphics don't interfere with the regular inline graphics. Here the instance
+used is \type {extrafun} and the name where the run is stored is \type {mydemo}.
+
+\startbuffer
+\startMPrun{extrafun::mydemo}
+    input mfun-mrun-demo.mp ;
+\stopMPrun
+
+\placefigure
+  {An external file can have multiple graphics. Here we show a few
+   images that we used to use on the \PRAGMA\ \CONTEXT\ website.}
+  {\startcombination[2*2]

+     {\externalfigure[mprun:extrafun::mydemo.4][height=6cm]} {team}
+   \stopcombination}
+\stopbuffer
+
+\typebuffer
+
+Keep in mind that the whole file will be processed (using the built in library)
+in order to get one graphic. Normally this is no big deal.

+
+\index{graphics+standalone}
+
+If you don't want to use \CONTEXT\ but still want to use \METAFUN, a rather
+convenient method is the following. Create a file that
+
+\starttyping
+\startMPpage
+    % Your mp code goes here. You can use the textext
+    % macro as discussed later to deal with typeset text.
+\stopMPpage
+\stoptyping
+
+When you process that file with the \type {context} command you will get a \PDF\
+file that you can include in any application that can embed a \PDF\ image. In
+this case your exposure to \CONTEXT\ is minimal.
+
+\stopsection
+
+\startsection[title={Graphic buffers}]
+
+\index{graphics+buffers}
+\index{buffers}
+
+In addition to the macros defined in the previous section, you can use \CONTEXT's
+buffers to handle graphics. This can be handy when making documentation, so it
+makes sense to spend a few words on them.
+
+A buffer is a container for content that is to be (re|)|used later on. The main
+reason for their existence is that they were needed for typesetting manuals and
+articles on \TEX. By putting the code snippets in buffers, we don't have to key
+in the code twice, since we can either show the code of buffers verbatim, or
+process the code as part of the text flow. This means that the risk of mismatch
+between the code shown and the typeset text is minimized.
+
+\startbuffer[a]
+\startbuffer
+You are reading the \METAFUN\ manual.
+\stopbuffer
+\stopbuffer
+
+\typebuffer[a]
+
+This buffer can be typeset verbatim using \type {\typebuffer} and processed using
+\type {\getbuffer}, as we will do now:
+
+\blank \getbuffer[a] \blank
+
+An other advantage of using buffers, is that they help you keeping the document
+source clean. In many places in this manual we put table or figure definitions in
+a buffer and pass the buffer to another command, like:
+
+\starttyping
+\placefigure{A very big table}{\getbuffer}
+\stoptyping
+
+Sometimes it makes sense to collect buffers in separate files. In that case we
+give them names.
+
+\startbuffer
+\startbuffer[mfun]
+You are reading the \METAFUN\ manual.
+\stopbuffer
+\stopbuffer
+
+This time we should say \type {\typebuffer[mfun]} to typeset the code verbatim.
+Instead of \TEX\ code, we can put \METAPOST\ definitions in buffers.
+
+\startbuffer
+\startbuffer[graphic]
+draw fullcircle scaled 2cm ;
+\stopbuffer
+\stopbuffer
+
+Buffers can be used to stepwise build graphics. By putting code in multiple
+buffers, you can selectively process this code.
+
+\startbuffer
+\startbuffer[red]
+drawoptions(withcolor .625red) ;
+\stopbuffer
+
+\startbuffer[yellow]
+drawoptions(withcolor .625yellow) ;
+\stopbuffer
+\stopbuffer
+
+\typebuffer
+
+We can now include the same graphic in two colors by simply using different
+buffers. This time we use the special command \type {\processMPbuffer}, since
+\type {\getbuffer} will typeset the code fragment, which is not what we want.
+
+\startbuffer
+\startlinecorrection[blank]
+\processMPbuffer[red,graphic]
+\stoplinecorrection
+\stopbuffer
+
+\typebuffer
+
+The line correction macros take care of proper spacing around the graphic. The
+\type {[blank]} directive tells \CONTEXT\ to add more space before and after the
+graphic.
+
+\startbuffer
+\startlinecorrection[blank]
+\processMPbuffer[yellow,graphic]
+\stoplinecorrection
+\stopbuffer
+
+\typebuffer
+
+Which mechanism you use, (multiple) buffers or (re|)|usable graphics, depends on
+your preferences. Buffers are slower but don't take memory, while (re|)|usable
+graphics are stored in memory which means that they are accessed faster.
+
+\stopsection
+
+\startsection[title={Communicating color}]
+
+\index{color}
+
+Now that color has moved to the desktop, even simple documents have become more
+colorful, so we need a way to consistently apply color to text as well as
+graphics. In \CONTEXT, colors are called by name.
+
+The next definitions demonstrate that we can define a color using different color
+models, \RGB\ or \CMYK. Depending on the configuration, \CONTEXT\ will convert
+one color system to the other, \RGB\ to \CMYK, or vice versa. The full repertoire
+of color components that can be set is as follows.
+
+\starttyping
+\definecolor[color one]  [r=.1, g=.2, b=.3]
+\definecolor[color two]  [c=.4, m=.5, y=.6, k=.7]
+\definecolor[color three][s=.8]
+\stoptyping
+
+The numbers are limited to the range $0\dots1$ and represent percentages. Black
+is represented by:
+
+\starttyping
+\definecolor[black 1] [r=0, g=0, b=0]
+\definecolor[black 2] [c=0, m=0, y=0, k=1]
+\definecolor[black 3] [s=0]
+\stoptyping
+
+Predefined colors are passed to \METAPOST\ graphics via the \type {\MPcolor}.
+First we define some colors.
+
+\starttyping
+\definecolor[darkyellow][y=.625] % a CMYK color
+\definecolor[darkred]   [r=.625] % a RGB color
+\definecolor[darkgray]  [s=.625] % a gray scale
+\stoptyping
+
+These are the colors we used in this document. The next example uses two of them.
+
+\startbuffer
+\startuseMPgraphic{color demo}
+  pickup pencircle scaled 1mm ;
+  path p ; p := fullcircle xscaled 10cm yscaled 1cm ;
+  fill p withcolor \MPcolor{darkgray} ;
+  draw p withcolor \MPcolor{darkred} ;
+\stopuseMPgraphic
+
+\useMPgraphic{color demo}
+\stopbuffer
+
+\typebuffer
+
+The previous example uses a pure \RGB\ red shade, combined with a gray fill.
+
+\startlinecorrection[blank]
+\getbuffer
+\stoplinecorrection
+
+Originally \METAPOST\ only supported only the \RGB\ and gray color spaces. In \METAFUN\
+we also supported \CMYK\ and spot colors, using an extension mechanism that hooked into
+the backend. At some point \METAPOST\ got native support for \CMYK. When you use mixed
+color models you need to be aware of the fact that their related variables have different
+types:
+
+\starttabulate[||T|T|]
+\NC gray \NC numeric   \NC s         \NC \NR
+\NC rgb  \NC color     \NC (r,g,b)   \NC \NR
+\NC cmyk \NC cmykcolor \NC (c,m,y,k) \NC \NR
+\stoptabulate
+
+Because in \METAFUN\ (\type {mpiv}) we hook deeply into the \CONTEXT\ color
+mechanisms we can use symbolic names instead. and these are just strings.
+
+There is a fundamental difference between a yellow as defined in \CONTEXT\ using
+\CMYK\ and a \RGB\ yellow.
+
+\startbuffer
+\definecolor[cmyyellow]    [y=1]
+\definecolor[rgbyellow]    [r=1,g=1]
+
+\definecolor[cmydarkyellow][y=.625]
+\definecolor[rgbdarkyellow][r=.625,g=.625]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\in {Figure} [fig:many yellows:pass] demonstrates what happens when we multiply
+colors by a factor. Since we are not dealing with real \CMYK\ colors,
+multiplication gives different results for \CMYK\ colors passed as \type
+{\MPcolor}. \in {Figure} [fig:many yellows:fetch] we show the same colors but
+this time we use a different method, one that avoids the \TEX\ macro. This method
+can be used in \MKIV. We will use both methods in examples.

+
+In order to prevent problems, we advise you to stick to \RGB\ color
+when you create documents for screen and \CMYK\ when producing for print.
+
+In the \METAFUN\ macro collection there is a macro \type {cmyk} that takes four
+arguments, representing the cyan, magenta, yellow, and black component. Nowadays
+you don't need it as we have native \CMYK.
+
+\startbuffer
+fill unitsquare xyscaled (10cm, 5mm) withcolor cmyk(1,0,.3,.3) ;
+fill unitsquare xyscaled (10cm,-5mm) withcolor     (1,.3,0,.3) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+If you take a close look at the numbers, you will notice that the cyan component
+results in a 100\% ink contribution. You will also notice that 30\% black ink is
+added. This means that we cannot safely convert this color to \RGB\ ($r=1-c-k<0$)
+without losing information. Nevertheless the previous blue bar is presented all
+right. This is due to the fact that in \METAFUN\ the \CMYK\ colors are handled as
+they should, even when \METAPOST\ does not support this color model.
+
+If you use this feature independent of \CONTEXT, you need to enable it by setting
+\type {cmykcolors} to \type {true}. You have to convert the resulting graphic to
+\PDF\ by using for instance the \type {mptopdf} suite.
+
+In \CONTEXT\ you can influence this conversion by changing parameters related to
+color handling:
+
+\starttyping
+\setupcolors[cmyk=yes,rgb=no]
+\stoptyping
+
+Unless you know what you are doing, you don't have to change the default settings
+(both \type {yes}). In the \CONTEXT\ reference manual you can also read how color
+reduction can be handled.
+
+Special care should be paid to gray scales. Combining equal quantities of the
+three color inks will not lead to a gray scale, but to a muddy brown shade.

+% \index{common definitions}
+%
+% When using many graphics, there is a chance that they share common definitions.
+% Such shared components can be defined by:
+%
+% \starttyping
+% \startMPinclusions
+%   color mycolor ; mycolor := .625red ;
+% \stopMPinclusions
+% \stoptyping
+%
+% {\em The following is only true for \CONTEXT\ \MKII ! Users of \MKIV\ can skip
+% this section.}
+%
+% All \METAPOST\ graphics defined in the document end up in the files \type
+% {mpgraph.mp} and \type {mprun.mp}. When processed, they produce (sometimes many)
+% graphic files. When you use \CONTEXT\ \MKII\ and \TEXEXEC\ to process documents,
+% these two files are processed automatically after a run so that in a next run,
+% the right graphics are available.
+%
+% When you are using the \type {web2c} distribution, \CONTEXT\ can call \METAPOST\
+% at runtime and thereby use the right graphics instantaneously. In order to use
+% this feature, you have to enable \type {\write18} in the file \type {texmf.cnf}.
+% Also, in the file \type {cont-sys.tex}, that holds local preferences, or in the
+% document source, you should say:
+%
+% \starttyping
+% \runMPgraphicstrue
+% \stoptyping
+%
+% This enables runtime generation of graphics using the low level \TEX\ command
+% \type {\write18}. First make sure that your local brand of \TEX\ supports this
+% feature. A simple test is making a \TEX\ file with the following line:
+%
+% \starttyping
+% \immediate\write18{echo It works}
+% \stoptyping
+%
+% If this fails, you should consult the manual that comes with your system, locate
+% an expert or ask around on the \CONTEXT\ mailing list. Of course you can also
+% decide to let \TEXEXEC\ take care of processing the graphics afterwards. This has
+% the advantage of being faster but has the disadvantage that you need additional
+% \TEX\ runs.
+%
+% If you generate the graphics at run time, you should consider to turn on graphic
+% slot recycling, which means that you often end up with fewer intermediate files:
+%
+% \starttyping
+% \recycleMPslotstrue
+% \stoptyping
+%
+% There are a few more low level switches and features, but these go beyond the
+% purpose of this manual. Some of these features, like the option to add tokens to
+% \type {\everyMPgraphic} are for experts only, and fooling around with them can
+% interfere with existing features.
+%
+% \stopsection
+
+\startsection[title={One page graphics}]
+
+An advantage of using \CONTEXT\ to make your \METAPOST\ graphics is you don't
+have to bother about specials, font inclusion and all those nasty things that can
+spoil a good day. An example of such a graphic is the file \type {mfun-800} that
+resides on the computer of the author.
+
+\typefile{mfun-800}
+
+Given that \CONTEXT\ is present on your system, you can process this file with:
+
+\starttyping
+context mfun-800
+\stoptyping
+
+You can define many graphics in one file. Later you can include individual pages
+from the resulting \PDF\ file in your document:
+
+\startbuffer
+\placefigure
+  {A silly figure, demonstrating that stand||alone||graphics
+   can be made.}
+  {\typesetfile[mfun-800.tex][page=1]}
+\stopbuffer
+
+\typebuffer
+
+In this case the \type {page=1} specification is not really needed. You can scale
+and manipulate the figure in any way supported by the macro package that you use.
+
+\getbuffer
+
+\stopsection
+
+\startsection[title={Managing resources}]
+
+A graphic consists of curves, either or not filled with a given color. A graphic
+can also include text, which means that fonts are used. Finally a graphic can
+have special effects, like a shaded fill. Colors, fonts and special effects go
+under the name resources, since they may demand special care or support from the
+viewing or printing device.
+
+% When fonts are used, a \METAPOST\ file is not self contained. This means that the
+% postprocessing program has to deal with the fonts. In \CONTEXT, the special
+% driver |<|and \PDFTEX\ support is considered as such|>| takes care of this.
+
+Special effects, like shading, are supported by dedicated \METAPOST\ modules.
+These are included in the \CONTEXT\ distribution and will be discussed later in
+\in {chapter} [sec:effects].
+
+Since \METAPOST\ supports color, an embedded graphic can be rather colorful.
+However, when color support is disabled or set up to convert colors to gray
+scales, \CONTEXT\ will convert the colors in the graphics to gray scales.

+You need to be aware of the fact that the results of a (for instance) double

+4096 base points) the outcome is probably not that different. However, we've seen
+that the accuracy of for instance $\pi$ (just a variable) differs. I like to use
+random values and the random generators are definitely different: each of the
+number libraries has its own implementation. Let's look at that. We define two

+    This document introduces you in the world of the graphic programming language
+    \MetaPost. Not only the language itself is covered in detail, but also the way to
+    interface with the typographic language \TeX. We also present the collection of
+    \MetaPost\ extensions that come with the \ConTeXt\ typesetting system. This
+    collection goes under the name \MetaFun.
+
+    \blank
+
+    All aspects of the \MetaPost\ language are covered. The first chapters focus on
+    the language itself, later chapters cover aspects like color, graphic
+    inclusions, adding labels, and stepwise constructing graphics. We finish with a
+    graphical overview of commands.

+\startintro
+
+For those who need to be inspired, we will demonstrate how \METAPOST\ can be used
+to enhance your document with simple graphics. In these examples we will try to
+be not too clever, simply because we lack the experience to be that clever. The
+real tricks can be found in the files that come with \METAPOST.
+
+\stopintro
+
+\startsection[reference={sec:coils,sec:springs},title={Simple drawings}]
+
+In the words of John Hobby, the creator of \METAPOST, \quotation {\METAPOST\ is
+particularly well||suited for generating figures for technical documents where
+some aspects of a picture may be controlled by mathematical or geometrical
+constraints that are best expressed symbolically. In other words, \METAPOST\ is
+not meant to take the place of a freehand drawing tool or even an interactive
+graphics editor}.
+
+An example of such a picture is the following one, which is dedicated to David
+Arnold, who asked me once how to draw a spring. So, imagine that we want to draw
+a schematic view of a system of four springs.
+
+\startbuffer[a]

+  ( ( (0,0) -- (0,h) --

+      (0,n+h) -- (0,n+2h) )
+    yscaled ((xpart (b-a) ++ ypart (b-a))/(n+2h))

+\startlinecorrection[blank]
+\processMPbuffer[a,d]
+\stoplinecorrection
+
+A rather natural way to define such a system is:
+
+\typebuffer[d]
+
+Here, the macro \type {spring} takes 5~arguments: two points, the width of the
+winding, the length of the connecting pieces, and the number of elements (half
+windings). The definition of \type {spring} is less complicated than readable.
+
+\typebuffer[a]
+
+First we build a path starting in the origin, going left or right depending on
+the counter being an odd number.
+
+\starttyping
+pat := (0,0) ;
+for i=1 upto n-1:
+  if odd(i) :
+    pat := pat -- (-w/2,i) ;
+  else :
+    pat := pat -- (+w/2,i) ;
+  fi ;
+endfor ;
+pat := pat -- (0,n) ;
+\stoptyping
+
+Once you are accustomed to the way \METAPOST\ interprets (specialists may say
+expand) the source code, you will start using \type {if} and \type {for}
+statements in assignments. The previous code can be converted in a one liner,
+using the pattern:
+
+\starttyping
+pat := for i=1 upto n-1: (x,y)-- endfor (0,n) ;
+\stoptyping
+
+The loop splits out a series of \type {(x,y)--} but the last point is added
+outside the loop. Otherwise \type {pat} would have ended with a dangling \type
+{--}. Of course we need to replace \type {(x,y)} by something meaningful, so we
+get:
+
+\starttyping
+pat := for i=1 upto n-1: (if odd(i):-fi w/2,i)--endfor (0,n) ;
+\stoptyping
+
+We scale this path to the length needed. The expression $b-a$ calculates a
+vector, starting at $a$ and ending at $b$. In \METAPOST, the expression \type
+{a++b} is identical to $\sqrt{a^2+b^2}$. Thus, the expression \typ {xpart (b-a)
+++ ypart (b-a)} calculates the length of the vector $b-a$. Because the unscaled
+spring has length $n+2h$, scaling by the expression \typ {((xpart (b-a) ++ ypart
+(b-a)) / (n+2h))} gives the spring the same length as the vector $b-a$.
+
+Because we have drawn our spring in the vertical position, we first rotate it 90
+degrees clockwise to a horizontal position, and then rotate it through an angle
+equal to the angle in which the vector $b-a$ is pointing. After that, we shift it
+to the first point. The main complications are that we also want to draw
+connecting lines at the beginning and end, as well as support springs that
+connect arbitrary points. Since no check is done on the parameters, you should be
+careful in using this macro.
+
+When we want to improve the readability, we have to use intermediate variables.
+Since the macro is expected to return a path, we must make sure that the content
+matches this expectation.
+
+\typebuffer[b]
+
+If you use \type {vardef}, then the last statement is the return value. Here,
+when \typ {p := spring (z1, z2, .75cm, 2, 10)} is being parsed, the macro is
+expanded, the variables are kept invisible for the assignment, and the path at
+the end is considered to be the return value. In a \type {def} the whole body of
+the macro is \quote {pasted} in the text, while in a \type {vardef} only the last
+line is visible. We will demonstrate this with a simple example.
+
+\starttyping
+def one = (n,n) ; n := n+1 ; enddef ;
+def two = n := n + 1 ; (n,n) enddef ;
+\stoptyping
+
+Now, when we say:
+
+\starttyping
+pair a, b ; numeric n ; n= 10 ; a := one ; b := two ;
+\stoptyping
+
+we definitely get an error message. This is because, when macro \type {two} is
+expanded, \METAPOST\ sees something:
+
+\starttyping
+b := n := n + 1 ;
+\stoptyping
+
+By changing the second definition in
+
+\starttyping
+vardef two = n := n + 1 ; (n,n) enddef ;
+\stoptyping
+
+the increment is expanded out of sight for \type {b :=} and the pair \type
+{(n,n)} is returned.
+
+We can draw a slightly better looking spring by drawing twice with a different
+pen. The following commands use the spring macro implemented by the \type
+{vardef}.
+
+\typebuffer[c]
+
+This time we get:
+
+\startlinecorrection[blank]
+\processMPbuffer[a,c]
+\stoplinecorrection
+
+Since the \type {spring} macro returns a path, you can do whatever is possible
+with a path, like drawing an arrow:
+
+\startlinecorrection[blank]
+\processMPbuffer[a,e]
+\stoplinecorrection
+
+Or even (watch how we use the neutral unit \type {u} to specify the dimensions):
+
+\startlinecorrection[blank]
+\processMPbuffer[a,f]
+\stoplinecorrection
+
+This was keyed in as:

+\typebuffer[e]
+
+and:
+
+\typebuffer[f]
+
+\stopsection
+
+\startsection[reference=sec:free labels,title={Free labels}]
+
+\index {labels}
+
+The \METAPOST\ label macro enables you to position text at certain points. This
+macro is kind of special, because it also enables you to influence the
+positioning. For that purpose it uses a special kind of syntax which we will not
+discuss here in detail.
+
+\startbuffer[a]
+pickup pencircle scaled 1mm ;
+path p ; p := fullcircle scaled 3cm ;
+draw p withcolor .625yellow ;

+dotlabel.urt  ("upper right" , point 1 of p) ;
+dotlabel.top  ("top"         , point 2 of p) ;
+dotlabel.ulft ("upper left"  , point 3 of p) ;

+dotlabel.lrt  ("lower right" , point 7 of p) ;
+\stopbuffer
+
+\typebuffer[a]
+
+The \type {label} command just typesets a text, while \type {dotlabel} also draws
+a dot at the position of the label. The \type {thelabel} (not shown here) command
+returns a picture.
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+There is a numeric constant \type {labeloffset} that can be set to influence the
+distance between the point given and the content of the label. When we set the
+offset to zero, we get the following output.
+
+\startbuffer[x]
+interim labeloffset := 0pt ; % local assignment
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a]
+\stoplinecorrection
+
+This kind of positioning works well as long as we know where we want the label to
+be placed. However, when we place labels automatically, for instance in a macro,
+we have to apply a few clever tricks. There are for sure many ways to accomplish
+this goal, but here we will follow the mathless method.
+
+\startbuffer[a]
+pickup pencircle scaled 1mm ;
+path p ; p := fullcircle scaled 3cm ;
+draw p withcolor .625yellow ;
+vardef do (expr str) =
+  save currentpicture ; picture currentpicture ;

+dotlabel.llft (do("lower left")  , point 5 of p) ;

+\stoplinecorrection
+
+The previous graphic visualizes the bounding box of the labels. This bounding box
+is rather tight and therefore the placement of labels will always be suboptimal.
+Compare the alignment of the left- and rightmost labels. The \type {btex}||\type
+{etex} method is better, since then we can add struts, like:
+
+\starttyping
+btex \strut right etex
+\stoptyping
+
+to force labels with uniform depths and heights. The next graphic demonstrates
+that this looks better indeed. Also, as \TEX\ does the typesetting we get the
+current text font instead of the label font and the content will be properly
+typeset; for instance kerning will be applied when applicable. Spending some time
+on such details pays back in better graphics.
+
+\startbuffer[b]
+dotlabel.rt   (do(btex \strut right       etex) , point 0 of p) ;
+dotlabel.urt  (do(btex \strut upper right etex) , point 1 of p) ;

+\startlinecorrection[blank]
+\processMPbuffer[x,a,b]
+\stoplinecorrection
+
+Now, what happens when we want to place labels in other positions? In the worst
+case, given that we place the labels manually, we end up in vague arguments in
+favour for one or the other placement.
+
+\startbuffer[y]
+p := p rotatedaround(center p, 22.5) ;
+\stopbuffer

+\startlinecorrection[blank]
+\processMPbuffer[x,a,y,b]
+\stoplinecorrection
+
+Although any automatic mechanism will be sub||optimal, we can give it a try to
+write a macro that deals with arbitrary locations. This macro will accept three
+arguments and return a picture.
+
+\starttyping
+thefreelabel("some string or picture",a position,the origin)
+\stoptyping
+
+Our testcase is just a simple \type {for} loop that places a series of labels.
+The \type {freedotlabel} macro is derived from \type {thefreelabel}.
+
+\startbuffer[c]
+pickup pencircle scaled 1mm ;
+path p ; p := fullcircle scaled 3cm ;
+draw p withcolor .625yellow ;
+for i=0 step .5 until 7.5 :
+  freedotlabel ("text" , point i of p, center p) ;
+endfor ;
+\stopbuffer
+
+\typebuffer[c]
+
+As a first step we will simply place the labels without any correction. We also
+visualize the bounding box.
+
+\startbuffer[b]
+vardef freedotlabel (expr str, loc, ori) =
+  drawdot loc ; draw thefreelabel(str,loc,ori) ;
+enddef ;
+
+vardef freelabel (expr str, loc, ori) =
+  draw thefreelabel(str,loc,ori) ;
+enddef ;
+\stopbuffer
+
+\startbuffer[a]
+vardef thefreelabel (expr str, loc, ori) =
+  save s ; picture s ; s := thelabel(str,loc) ;
+  draw boundingbox s withpen pencircle scaled .5pt ;
+  s
+enddef ;
+\stopbuffer
+
+\typebuffer[a]
+
+To make our lives more easy, we also define a macro that draws the dot as well as
+a macro that draws the label.
+
+\typebuffer[b]
+
+Now we get:
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a,b,c]
+\stoplinecorrection
+
+The original label macros permits us to align the label at positions, 4~corners
+and 4~points halfway the sides. It happens that circles are also composed of
+8~points. Because in most cases the label is to be positioned in the direction of
+the center of a curve and the point at hand, it makes sense to take circles as
+the starting points for positioning the labels.
+
+To help us in positioning, we define a special square path, \type {freesquare}.
+This path is constructed out of 8~points that match the positions that are used
+to align labels.
+
+\startbuffer[d]
+path freesquare ;
+
+freesquare := ((-1,0)--(-1,-1)--(0,-1)--(+1,-1)--
+               (+1,0)--(+1,+1)--(0,+1)--(-1,+1)--cycle) scaled .5 ;
+\stopbuffer
+
+\typebuffer[d]
+
+We now show this free path together with a circle, using the following
+definitions:
+
+\startbuffer[e]
+drawpath        fullcircle scaled 3cm ;
+drawpoints      fullcircle scaled 3cm ;
+drawpointlabels fullcircle scaled 3cm ;
+currentpicture := currentpicture shifted (5cm,0) ;
+drawpath        freesquare scaled 3cm ;
+drawpoints      freesquare scaled 3cm ;
+drawpointlabels freesquare scaled 3cm ;
+\stopbuffer
+
+\typebuffer[e]
+
+We use two drawing macros that are part of the suite of visual debugging macros.
+
+\startlinecorrection[blank]
+\processMPbuffer[x,d,e]
+\stoplinecorrection
+
+As you can see, point~1 is the corner point that suits best for alignment when a
+label is put at point~1 of the circle. We will now rewrite \type {thefreelabel}
+in such a way that the appropriate point of the associated \type {freesquare} is
+found.
+
+\startbuffer[a]
+vardef thefreelabel (expr str, loc, ori) =
+  save s, p, q, l ; picture s ; path p, q ; pair l ;
+  s := thelabel(str,loc) ;
+  p := fullcircle scaled (2*length(loc-ori)) shifted ori ;
+  q := freesquare xyscaled (urcorner s - llcorner s) ;
+  l := point (xpart (p intersectiontimes (ori--loc))) of q ;
+  draw q shifted loc withpen pencircle scaled .5pt ;
+  draw l shifted loc withcolor .625yellow ;
+  draw loc withcolor .625red ;
+  s
+enddef ;
+\stopbuffer
+
+\typebuffer[a]
+
+The macro xyscaled is part of \METAFUN\ and scales in two directions at once. The
+\METAPOST\ primitive \type {intersectiontimes} returns a pair of time values of
+the point where two paths intersect. The first part of the pair concerns the
+first path.
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a,b,c]
+\stoplinecorrection
+
+We are now a small step from the exact placement. If we change the last line of
+the macro into:
+
+\starttyping
+(s shifted -l)
+\stoptyping
+
+we get the displacement we want. Although the final look and feel is also
+determined by the text itself, the average result is quite acceptable.
+
+\startbuffer[a]
+vardef thefreelabel (expr str, loc, ori) =
+  save s, p, q, l ; picture s ; path p, q ; pair l ;

+enddef ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a,b,c]
+\stoplinecorrection
+
+Because we also want to pass pictures, and add a bit of offset too, the final
+implementation is slightly more complicated. The picture is handled with an
+additional condition, and the offset with the \METAFUN\ macro \type {enlarged}.
+
+\startbuffer[a]

+
+vardef thefreelabel (expr str, loc, ori) =

+\typebuffer[a]
+
+Watch how we temporarily enlarge the bounding box of the typeset label text. We

+A convenient \METAPOST\ macro is \type {unitvector}. When we draw a line segment
+from the origin to the point returned by this macro, the segment has a length of
+1~base point. This macro has a wide range of applications, but some basic
+knowledge of vector algebra is handy. The following lines of \METAPOST\ code
+demonstrate the basics behind unitvectors.
+

+  drawarrow origin--unitvector(i) scaled 1cm withcolor .625yellow ;
+endfor ;

+
+The circle has a radius of 1cm, and the three line segments are drawn from the
+origin in the direction of the points that are passed as arguments. Because the
+vector has length of~1, we scale it to the radius to let it touch the circle. By
+setting \type {autoarrows} we make sure that the arrowheads are scaled
+proportionally to the linewidth of 1~mm.

+An application of this macro is drawing the angle between two lines. In the
+\METAPOST\ manual you can find two macros for drawing angles: \type {mark_angle}
+and \type {mark_rt_angle}. You may want to take a look at their definitions
+before we start developing our own alternatives.

+The previous graphic demonstrates what we want to accomplish: a circular curve
+indicating the angle between two straight lines. The lines and curve are drawn
+with the code:
+
+\typebuffer[b]
+
+where \type {anglebetween} is defined as:
+
+\typebuffer[a]
+
+Both unitvectors return just a point on the line positioned 1~unit (later scaled
+to 1cm) from the origin. We connect these points by a curve that starts in the
+direction at the first point. If we omit the \type {a rotated 90} direction
+specifier, we get:
+
+\startbuffer[a]
+def anglebetween (expr a, b) =
+  (unitvector(a) .. unitvector(b))
+enddef ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a,b]
+\stoplinecorrection
+
+These definitions of \type {anglebetween} are far from perfect. If we don't start
+in the origin, we get the curve in the wrong place and when we swap both points,
+we get the wrong curve.
+
+\startbuffer[a]
+def anglebetween (expr endofa, endofb, common, length) =

+\stopbuffer
+
+The solution for the displacement is given in the \METAPOST\ manual and looks
+like this (we package the macro a bit different):
+
+\typebuffer[a]
+
+As you can see, we compensate for the origin of both vectors. This macro is
+called with a few more parameters. We need to pass the length, since we want to
+add the shift to the macro and the shift takes place after the scaling.
+
+\typebuffer[b]
+
+That the results are indeed correct, is demonstrated by the output of following
+example:
+
+\startlinecorrection[blank]
+\processMPbuffer[x,a,b]
+\stoplinecorrection
+
+However, when we swap the points, we get:
+
+\startbuffer[a]
+def anglebetween (expr endofb, endofa, common, length) =
+  (unitvector (endofa-common){(endofa-common) rotated 90} ..
+   unitvector (endofb-common)) scaled length shifted common
+enddef ;
+\stopbuffer

+\startlinecorrection[blank]
+\processMPbuffer[x,a,b]
+\stoplinecorrection
+
+This means that instead of rotating over $90$ degrees, we have to rotate over
+$-90$ or $270$ degrees. That way the arrow will also point in the other
+direction. There are undoubtedly more ways to determine the direction, but the
+following method also demonstrates the use of \type {turningnumber}, which
+reports the direction of a path. For this purpose we compose a dummy cyclic path.
+
+\startbuffer[a]
+vardef anglebetween (expr endofa, endofb, common, length) =
+  save tn ; tn := turningnumber(common--endofa--endofb--cycle) ;

+   unitvector(endofb-common)) scaled length shifted common
+enddef ;
+\stopbuffer
+
+\typebuffer[a]
+
+Because we use an intermediate variable, just to keep things readable, we have to
+use \type {vardef} to hide the assignment for the outside world. We demonstrate
+this macro using the following code:
+
+\startbuffer[b]
+pair a, b, c ; a := (2cm,-1cm) ; b := (3cm,1cm) ; c := (-1cm,.5cm) ;
+drawarrow c--a ; drawarrow c--b ;

+Watch how both arrows point in the direction of the line that is determined by
+the second point.

+We need to calculate seven paths. The first implementation does all the handywork
+itself and thereby is rather long, complicated and unreadable. It does not really
+use the strength of \METAPOST\ yet.
+
+\typebuffer[circle]
+
+In determining the right intersection points, you need to know where the path
+starts and in what direction it moves. In case of doubt, drawing the path as an
+arrow helps. If you want to see the small paths used, you need to comment the
+lines with the \type {fill}'s and uncomment the lines with \type {draw}'s. Due to
+the symmetry and the fact that we keep the figure centered around the origin, we
+only need to calculate two paths since we can rotate them.
+
+There are for sure more (efficient) ways to draw such a figure, but this one
+demonstrates a few new tricks, like grouping. We use grouping here because we
+want to use \type {mm} to indicate the magenta path, and \type {mm} normally
+means millimeter. Within a group, you can save variables. These get their old
+values when the group is left.
+
+With \type {for} we process multiple paths after each other. In this case it
+hardly saves tokens, but it looks more clever.
+
+One of the more efficient methods is using the \type {buildcycle} macro. This
+macro takes two or more paths and calculates the combined path. Although this is
+a rather clever macro, you should be prepared to help it a bit when paths have
+multiple intersection points. Again, we could follow a more secure mathematical
+method, but the next one took only a few minutes of trial and error. To save some
+memory, we redefine the \type {colors} graphic.

+We did not mention what the push and pop commands are responsible for. Scaling
+the current picture is well defined as long as we deal with one graphic. However,
+if the current picture already has some content, this content is also scaled. The
+push and pop commands let us add content to the current picture as well as
+manipulating the picture as a whole without any side effects. The final result is
+put on top of the already drawn content. Instead of the sequence:
+
+\starttyping
+pushcurrentpicture ;
+  ...
+  currentpicture := currentpicture ... transformations ... ;
+popcurrentpicture ;
+\stoptyping
+
+you can say:
+
+\starttyping
+pushcurrentpicture ;
+  ...
+popcurrentpicture ... transformations ... ;
+\stoptyping
+
+Both are equivalent to:
+
+\starttyping
+draw image ( ... ) ... transformations ... ;

+
+For larger sequences of commands, the push||pop alternative gives a bit more more

+
+Unless you belong to the happy few whose visual capabilities are not distorted by
+neural optimizations, in \in {figure} [fig:tricked 1] the gray rectangles at the
+left look lighter than those on the right. Alas, you can fool yourself, but
+\METAPOST\ does not cheat. This graphic, referred to as White's illusion, is
+defined as follows.
+
+\typebuffer[a]
+
+Watch how we include the code directly. We have packaged this graphic in a buffer
+which we include as a floating figure.
+
+\typebuffer[b]
+
+When passed to \METAPOST, this code is encapsulated in its \type {beginfig} and
+\type {endfig} macros and thereby grouped. But any change to a variable that is
+not explicitly saved, migrates to the outer level. In order to prevent all
+successive graphics to have butt'd linecaps, we have to change this line
+characteristic locally. Because \type {linecap} is defined as an internal
+variable, we have to use \type {interim} to overload its value. Because \type {u}
+is a rather commonly used scratch variable, we don't save its value.
+
+Watch how we use \type {u} as the loop step. In spite of what your eyes tell you,
+this graphic only has two explicit color directives, both being 50\% black. In
+the next example we will use some real colors.

+
+In \in {figure} [fig:tricked 2] the small squares in the center of each colored
+pair of big squares have the same shade, but the way we perceive them are
+influenced by their surroundings. Both sets of squares are defined using usable
+graphics. The top squares are defined as:
+
+\typebuffer[b]
+
+and the bottom squares are coded as:
+
+\typebuffer[c]
+
+Because both graphics share code, we have defined that code as a separate
+graphic, that we include. The only point of interest in this definition is the
+fact that we let \METAPOST\ interpolate between the two colors using \type {.5[
+]}.
+
+\typebuffer[a]
+
+The color \type {funcolor} is provided by \CONTEXT, and since we want to use this
+graphic with different colors, this kind of mapping is quite convenient. The
+bunch of graphics is packaged in a combination with empty captions. Note how we
+set the color before we include the graphic.

+
+The graphics of the second row extends those of the first by drawing a white line

+\startsection[title={Growing graphics}]
+
+Although \METAPOST\ is not really suited as a simulation engine, it is possible
+to build graphics that are built and displayed incrementally with a sequence of
+mouse clicks. The following example is the result of an email discussion David
+Arnold and the author had while \METAFUN\ evolved.
+
+Instead of defining the graphics in a separate \METAPOST\ file, we will
+incorporate them in the document source in which they are used. We can use
+several methods.
+
+\startitemize[n]
+\startitem
+    Define macros and figures in a separate file and include the graphics as
+    external graphics.
+\stopitem
+\startitem
+    Define everything in the document source as usable graphics and include the
+    graphics using \type {\useMPgraphic}.
+\stopitem
+\startitem
+    Package the graphic components in buffers and paste those together as
+    graphics that can be processed at run time.
+\stopitem
+\stopitemize
+
+The first method is the most independent one, which has its advantages if we want
+to use the graphics in other applications too. The second method works well in
+graphics where parts of the definitions change between invocations of the
+graphic. This method follows the template:
+
+\starttyping
+\startuseMPgraphic{whatever}
+ ...
+\stopuseMPgraphic
+
+\startuseMPgraphic{result}
+  ...
+  \includeMPgraphic{whatever}
+  ...
+\stopuseMPgraphic
+
+\useMPgraphic{result}
+\stoptyping
+
+The disadvantage of this method is that it cannot be combined with \type
+{btex}||\type {etex} since it is nearly impossible to determine when, how, and to
+what extent the content of a graphic should be expanded before writing it to the
+temporary \METAPOST\ file.
+
+Therefore, we will demonstrate how buffers can be used. This third method closely
+parallels the first way of defining graphics. A nice side effect is that we can
+easily typeset these buffers verbatim, which we did to typeset this document.
+
+We are going to do a classic compass and straightedge construction, the bisection
+of a line segment joining two arbitrary points. We will construct five graphics,
+where each one displays one step of the construction. We will embed each graphic
+in a start||stop command. Later we will see the advantage of this strategy.

+We are going to draw a few dots, and to force consistency we first define a macro

+The code in this buffer executes the preceding macros. The \type {..._everything}

+This graphic can now be embedded by the \CONTEXT\ command
+\type {\processMPbuffer}. This command, like the ordinary

+We use \type {\ruledhbox} to show the tight bounding box of the graphic. The line
+correction takes care of proper spacing around non textual content, like
+graphics. \footnote {These spacing commands try to get the spacing around the
+content visually compatible, and take the height and depth of the preceding and
+following text into account.} This is only needed when the graphic is part of the
+text flow!
+
+\getbuffer
+
+Next, we draw two circles of equal radius, one centered at point $A$, the other
+at point $B$.
+
+\startbuffer
+\startbuffer[d]
+def draw_circles =
+  path circleA, circleB ; numeric radius, distance ;

+
+\startlinecorrection[blank]
+\ruledhbox{\processMPbuffer[a,b,c,d,2]}
+\stoplinecorrection
+
+The next step in the construction of the perpendicular bisector requires that we
+find and label the points of intersection of the two circles centered at points
+$A$ and $B$. The intersection points are calculated as follows. Watch the \type
+{reverse} operation, which makes sure that we get the second intersection point.
+
+\startbuffer
+\startbuffer[e]
+def draw_intersection =
+  pair pointC, pointD ;
+  pointC := circleA intersectionpoint circleB ;

+In placing the label, we must make sure that the text runs free of the lines and

+At the start of this section, we mentioned three methods. When we use the first
+method of putting all the graphics in an external \METAPOST\ file, the following
+framework suits. We assume that the file is called \type {step.mp} and that it is
+kept by the user along with his document source. We start with the definitions of
+the graphic steps. These are the same as the ones shown previously.
+
+\starttyping
+def draw_basics       = ... enddef ;
+def draw_circles      = ... enddef ;
+def draw_intersection = ... enddef ;
+def draw_bisector     = ... enddef ;
+def draw_midpoint     = ... enddef ;
+def stand_out         = ... enddef ;
+\stoptyping
+
+We can safe some code by letting the \type {..._everything} take care of the
+\type {beginfig} and \type {endfig} macros.
+
+\starttyping
+def start_everything (expr n) = beginfig(n) ; ... enddef ;
+def stop_everything           =    ... ; endfig ; enddef ;
+\stoptyping
+
+The five graphics now become:
+
+\starttyping
+start_everything (1) ;
+  stand_out ; draw_basics ;
+stop_everything ;
+
+start_everything (2) ;
+  draw_basics ; stand_out ; draw_circles ;

+
+start_everything (5) ;
+  draw_basics ; draw_circles ; draw_intersection ; draw_bisector ;
+  stand_out ; draw_midpoint ;

+\stoptyping
+
+The definitions of the symbols now refer to an external

+
+Which method is used, depends on the way the graphics are used. In this example

+
+Many company logos earn their beauty from their simplicity. One of the logos that
+most Dutch people have imprinted in their mind is that of the Dutch Railway
+Company (NS). An interesting feature of this logo is that, although it is widely
+known, drawing it on a piece of paper from mind is a task that many people fail.
+
+\startlinecorrection[blank]
+\processMPbuffer[ns]
+\stoplinecorrection
+
+This logo makes a good candidate for demonstrating a few fine points of drawing
+graphics, like using linear equations, setting line drawing characteristics,
+clipping and manipulating bounding boxes.
+
+The implementation below is quite certainly not according to the official
+specifications, but it can nevertheless serve as an example of defining such
+logos.
+
+\startbuffer[a]
+numeric width  ; width  = 3cm ;
+numeric height ; height = width/2 ;
+numeric line   ; line   = height/4 ;
+\stopbuffer
+
+As always, we need to determine the dimensions first. Here, both the height and
+line width depend on the width of the graphic.
+
+Instead of calculating the blue shape such that it will be a filled outline, we
+will draw the logo shape using line segments. This is why we need the \type
+{line} parameter.
+
+\typebuffer[a]
+
+We want sharp corners which can be achieved by setting \type {linejoin} to \type
+{mitered}.
+
+\startbuffer[b]
+linejoin := mitered ; pickup pencircle scaled line ;
+\stopbuffer
+
+\typebuffer[b]
+
+The colors are rather primary blue and yellow. At the time of writing this
+manual, Dutch trains are still painted yellow, so we will use that shade as
+background color.
+
+\startbuffer[c]
+color nsblue   ; nsblue   := (0,0,1) ;
+color nsyellow ; nsyellow := (1,1,0) ;
+\stopbuffer
+
+\typebuffer[c]
+
+We will now describe the main curves. Although these expressions are not that
+advanced, they demonstrate that we can express relationships instead of using
+assignments.
+
+\startbuffer[d]
+z1 = (0, height/2) ;
+z2 = (width/2-height/4, y1) ;
+z3 = (width/2+height/4, y4) ;
+z4 = (width, 0) ;
+
+path p ; p := z1--z2--z3--z4 ;
+\stopbuffer
+
+\typebuffer[d]
+
+Although it is accepted to consider \type {z} to be a variable, it is in fact a
+\type {vardef} macro, that expands into a pair \type {(x,y)}. This means that the
+previous definitions internally become:
+
+\starttyping
+(x1,y1) = (0, height/2) ;
+(x2,y2) = (width/2-height/4, y1) ;
+(x3,y3) = (width/2+height/4, y4) ;
+(x4,y4) = (width, 0) ;
+\stoptyping
+
+These 8 relations can be solved by \METAPOST, since all dependencies are known.
+
+\starttyping
+x1 = 0                ; y1 = height/2 ;
+x2 = width/2-height/4 ; y2 = y1       ;
+x3 = width/2+height/4 ; y3 = y4       ;
+x4 = width            ; y4 = 0        ;
+\stoptyping
+
+Since we express the variables \type {x} and \type {y} in terms of relations, we
+cannot reuse them, because that would mean that inconsistent relations occur. So,
+the following lines will lead to an error message:
+
+\starttyping
+z1 = (10,20) ; z1 = (30,50) ;
+\stoptyping
+
+For similar reasons, we may not assign a value (using \type {:=}) to such a \type
+{z} variable. Within a \METAPOST\ figure, \type {z} variables are automatically
+saved, which means that they can be reused for each figure.
+
+\startbuffer[x]
+drawpath p ; drawpoints p ; drawpointlabels p ;
+\stopbuffer
+
+So far, we have defined the following segment of the logo.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,x]
+\stoplinecorrection
+
+\startbuffer[e]
+z5 = (x4+height/2, y1) ;
+z6 = (x4, 2y1) ;
+z7 = 1.5[z5,z6] ;
+
+path q ; q := z3--z4--z5--z7 ;
+\stopbuffer
+
+The next expressions are used to define the second segment. The third expression
+determines \type {z7} to be positioned on the line \type {z5--z6}, where we
+extend this line by 50\%.
+
+\typebuffer[e]
+
+\startbuffer[x]
+drawpath q ; drawpoints q ; drawpointlabels q ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,x]
+\stoplinecorrection
+
+If we combine these two segments, we get:
+
+\startbuffer[x]
+drawpath p ; drawpoints p ; drawpointlabels p ;
+swappointlabels := true ;
+drawpath q ; drawpoints q ; drawpointlabels q ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,x]
+\stoplinecorrection
+
+However, when we draw them using the right linewidth and color, you will notice
+that we're not yet done:
+
+\startbuffer[f]
+draw p withcolor nsblue ; draw q withcolor nsblue ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f]
+\stoplinecorrection
+
+The second curve is similar to the first one, but rotated over 180 degrees.
+
+\startbuffer[g]
+addto currentpicture also currentpicture
+  rotatedaround (.5[z2,z3],180) shifted (height/4,height/2) ;
+\stopbuffer
+
+\typebuffer[g]
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g]
+\stoplinecorrection
+
+In order to get the sharp edges, we need to clip off part of
+the curves and at first sight, we may consider using a
+scaled bounding box. However, when we show the natural
+bounding box, you will notice that a more complicated bit of
+calculations is needed.
+
+\startbuffer[x]
+draw boundingbox currentpicture
+  withpen pencircle scaled .5mm withcolor .625white ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g,x]
+\stoplinecorrection
+
+The right clip path is calculated using the following expressions. Watch how we
+use \type {rt} and \type {top} to correct for the linewidth.
+
+\startbuffer[h]
+numeric d, lx, ly, ux, uy ; d = line/2 ;
+
+lx = -3d - d/3  ; ly = -d ; ux = rt x5 + d/3 ; uy = top y6 ;
+
+path r ; r := (lx,ly)--(ux,ly)--(ux,uy)--(lx,uy)--cycle;
+\stopbuffer
+
+\typebuffer[h]
+
+The clipping path is applied by saying:
+
+\startbuffer[i]
+clip currentpicture to r ;
+\stopbuffer
+
+\typebuffer[i]
+
+The result is quite acceptable:
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g,h,i]
+\stoplinecorrection
+
+But, if you watch closely to how this graphic extends into to left margin of this
+document, you will see that the bounding box is not yet right.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g,h,i,x]
+\stoplinecorrection
+
+\startbuffer[j]
+setbounds currentpicture to r ;
+\stopbuffer
+
+\typebuffer[j]
+
+We use the same path \type {r} to correct the bounding box.
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g,h,i,j,x]
+\stoplinecorrection
+
+There are a few subtle points involved, like setting the \type {linejoin}
+variable. If we had not set it to \type {mitered}, we would have got round
+corners. We don't set the \type {linecap}, because a flat cap would not extend
+far enough into the touching curve and would have left a small hole. The next
+example shows what happens if we set these variables to the wrong values:
+
+\startbuffer[bb]
+linejoin := rounded ; linecap := mitered ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,bb,c,d,e,f,g,h,i,j]
+\stoplinecorrection
+
+In fact we misuse the fact that both curves overlay each other.
+
+\startbuffer[f]
+draw p withcolor nsblue ; draw q withcolor .625white ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b,c,d,e,f,g,h,i,j]
+\stoplinecorrection
+
+The complete logo definition is a bit more extensive because we also want to add
+a background. Because we need to clip the blue foreground graphic, we must
+temporarily store it when we fill the background.
+
+\typebuffer[ns]
+
+For practical use it makes sense to package this definition in a macro to which
+we pass the dimensions.
+
+\stopsection
+
+\startsection[title={Music sheets}]
+
+The next example demonstrates quite some features. Imagine that we want to make
+us a couple of sheets so that we can write a musical masterpiece. Let's also
+forget that \TEX\ can draw lines, which means that somehow we need to use
+\METAPOST.
+
+Drawing a bar is not that complicated as the following code demonstrates.
+
+\startbuffer
+\startusableMPgraphic{bar}
+  vardef MusicBar (expr width, gap, linewidth, barwidth) =
+    image
+      ( interim linecap := butt ;
+        for i=1 upto 5 :
+          draw ((0,0)--(width,0)) shifted (0,(i-1)*gap)
+            withpen pencircle scaled linewidth ;
+        endfor ;
+        for i=llcorner currentpicture -- ulcorner currentpicture ,
+              lrcorner currentpicture -- urcorner currentpicture :
+          draw i withpen pencircle scaled barwidth ;
+        endfor ; )
+  enddef ;
+\stopusableMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can define the sidebars a bit more efficient using two predefined subpaths:
+
+\starttyping
+for i=leftboundary currentpicture, rightboundary currentpicture :
+\stoptyping
+
+We define a macro \type {MusicBar} that takes four arguments. The first two
+determine the dimensions, the last two concern the line widths. Now watch how we
+can use this macro:
+
+\startbuffer
+\includeMPgraphic{bar} ;
+draw MusicBar (200pt, 6pt, 1pt, 2pt) ;
+draw MusicBar (300pt, 6pt, 1pt, 2pt) shifted (0,-30pt) ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+As you can see in this example, the bar is a picture that can be transformed
+(shifted in our case). However, a close look at the macro teaches us that it does
+a couple of draws too. This is possible because we wrap the whole in an image
+using the \type {image} macro. This macro temporary saves the current picture,
+and at the end puts the old \type {currentpicture} under the new one.
+
+We wrap the whole in a \type {vardef}. This means that the image is returned as
+if it was a variable. Actually, the last thing in a \type {vardef} should be a
+proper return value, in our case a picture. This also means that we may not end
+the \type {vardef} with a semi colon. So, when the content of the \type {vardef}
+is expanded, we get something
+
+\starttyping
+draw some_picture ... ;
+\stoptyping
+
+Because we are still drawing something, we can add transform directives and set
+attributes, like the color.
+
+The second \type {for} loop demonstrates two nice features. Instead of repeating
+the draw operation by copying code, we apply it to a list, in our case a list of
+paths. This list contains two simple line paths. Because an \type {image} starts
+with a fresh \type {currentpicture}, we can safely use the bounding box data to
+determine the height of the line.
+
+The next step in producing the sheets of paper is to put several bars on a page,
+preferable with the width of the current text. This time we will use a reusable
+graphic, because each bar is the same.
+
+\startbuffer
+\startreusableMPgraphic{bars}
+  \includeMPgraphic{bar} ;
+  draw MusicBar (TextWidth, 6pt, 1pt, 2pt) withcolor .625yellow ;
+\stopreusableMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startlinecorrection[blank]
+\reuseMPgraphic{bars}
+\stoplinecorrection
+
+Instead of going through the trouble of letting \METAPOST\ calculate the positions
+of the bars, we will use \TEX. We put 12 bars on a page and let \TEX\ take care
+of the inter||bar spacing. Because we only want stretchable space between bars,
+called glue in \TEX, we need to remove the last added glue.

+\startsection[title={The euro symbol}]
+
+When Patrick Gundlach posted a nice \METAPOST\ version of the euro symbol to the
+\CONTEXT\ discussion list, he added the comment \quotation {The official
+construction is ambiguous: how thick are the horizontal bars? How much do they
+stick out to the left? Is this thing a circle or what? Are the angles on the left
+side of the bars the same as the one on the right side? \unknown} The alternative
+below is probably not as official as his, but permits a finetuning. You are
+warned: whatever you try, the euro {\em is} and {\em will remain} an ugly symbol.
+
+We use a couple of global variables to control the euro shape within reasonable
+bounds. Then we define two circles. Next we define a vertical line that we use in
+a couple of cut and paste operations. Watch how the top left point of the outer
+circle determines the slant of the line that we use to slice the vertical bars.

+general purpose tools, even at the cost of quite some effort or suboptimal
+results. Imagine that you are under way from our planet to Mars. After a long
+period of sleep you wake up and start wondering on what track you are. You even
+start questioning the experts that send you on your way, so you pop open your
+laptop, launch your editor and start metaposting.
+
+First you need to determine the begin and end points of your journey. For now it
+is enough to know the relative angle of the paths that both planets follow as
+well as the path themselves. We assume circular paths.
+

+draw point 0 of b withpen pencircle scaled 2mm ;
+\stopbuffer
+
+\typebuffer
+
+The rotation 120 can be calculated from the relative starting points and time the
+journey will take. Alternatively we can use the time along the path, but this
+would be a bit more fuzzy later on. \footnote {In case you wonder why \METAPOST\
+talks about the time on a path, you now have a cue.}
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+After a bit of playing with drawing paths between the two points, you decide to
+make a macro. We want to feed the angle between the paths but also the connecting
+path. So, we have to pass a path, but unfortunately we don't have direct access
+to the points. By splitting the argument definition we can pass an expression
+first, and a wildcard argument next.

+Because at this distance nobody will bother us with the thickness of the pen and
+colors, we code them the hard way. We create our own universe by setting a fixed
+boundingbox.
+
+We leave the Earth in the most popular way, straight upwards and after a few
+cycles, we leave it parallel to the surface. The path drawn reminds much of the
+trajectories shown in popular magazines.

+In the end we decide that although the trajectories look impressive, we will not

+controls and tensions.

+\startsection[title={Selective randomization}]
+
+In this document we have used a lot of randomization. Because \CONTEXT\ often
+needs multiple runs to sort out cross references, positions, tables of contents,
+and so on, being real random every run would result in endless runs to get things
+right, because the size of graphics changes. This is prevented by storing the
+random seed betweeen runs. You can remove the \type {tuc} file to get a new seed
+(or run \type {context --purgeall}).
+
+Here is another example of randomization. This time we only randomize the control
+points so the main shape sort of remains intact which can be handy when you use
+such random shapes around text but still want a predictable size.

+There are quite some helpers in \METAFUN\ and I must admit that I forgot

+some limitations as the following examples demonstrate: arrows don't work well

+\startintro
+
+\METAPOST\ provides a wide range of functions, like \type {sind} and \type
+{floor}. We will discuss most of them here and define a few more. We will also
+introduce a few methods for drawing grids and functions.
+
+\stopintro
+
+\startsection[title={Overview}]
+
+What follows is a short overview of the functions that can be applied to numeric
+expressions and strings. Functions that operate on pairs, colors, paths and
+pictures are discussed in other chapters.
+
+First of all we have \type {+}, \type {-}, \type {/} and \type {*}. For as far as
+is reasonable, you can apply these to numerics, pairs and colors. Strings can be
+concatenated by \type {&}.
+
+Pythagorean addition is accomplished by \type {++}, while Pythagorean subtraction
+is handled by \type {+-+}. The \type {**} operator gives you exponentiation. The
+nature of the \METAPOST\ language is such that you can easily define interesting
+functions using such symbols.
+
+The logarithmic functions are based on bytes. This makes them quite accurate but
+forces you to think like a computer.
+
+\starttabulate[|lT|l|]
+\HL
+\NC mexp(x) \NC expential function with base 256 \NC \NR
+\NC mlog(x) \NC logarithm with base 256          \NC \NR
+\HL
+\stoptabulate
+
+The basic goniometric functions operate on degrees, which is why they have a
+\quote {d} in their name.
+
+\starttabulate[|lT|l|]
+\HL
+\NC cosd(x) \NC cosine of $x$ with $x$ in degrees \NC \NR
+\NC sind(x) \NC sine of $x$ with $x$ in degrees   \NC \NR
+\HL
+\stoptabulate

+With \type {substring (i,j) of s} you can filter the substring bounded by the

+In \METAFUN\ we provide a few more functions (you can take a look in \type

+\index{grids}
+\index{axis}
+
+Some day you may want to use \METAPOST\ to draw a function like graphic. In the
+regular \TEX\ distributions you will find a module \type {graph.mp} that provides
+many ways to accomplish this. For the moment, \METAFUN\ does not provide advanced
+features with respect to drawing functions, so this section will be relatively
+short.
+
+When drawing a functions (for educational purposes) we need to draw a couple of
+axis or a grid as well as a shape. Along the axis we can put labels. For this we
+can use the \METAPOST\ package \type {format.mp}, but this does not integrate
+that well into the way \METAFUN\ deals with text typeset by \TEX.
+
+For those who love dirty tricks and clever macros, close reading of the code in
+\type {format.mp} may be worthwhile. The format macros in there use \TEX\ to
+typeset the core components of a number, and use the dimensions of those
+components to compose combinations of signs, numbers and superscripts.
+
+In \METAFUN\ we have the module \type {mp-form.mp} which contains most of the
+code in \type {format.mp} but in a form that is a bit more suited for fine
+tuning. This permits us to use either the composition method, or to fall back on
+the \type {textext} method that is part of \METAFUN. That way we can also handle
+fonts that have digits with different dimensions. Another \quote {change}
+concerns the pattern separator. Instead of a \type {%} we use \type {@}; you can
+choose to set another separator, but for embedded definitions \type {%} is
+definitely a bad choice because \TEX\ sees it as a comment and ignores everything
+following it.

+Using macros like these often involves a bit of trial and error. The arguments to
+these macros are as follows:
+
+\starttyping
+hlingrid (Min, Max, Step, Length, Width)
+vlingrid (Min, Max, Step, Length, Height)
+hloggrid (Min, Max, Step, Length, Width)
+vloggrid (Min, Max, Step, Length, Height)
+\stoptyping
+
+The macros take the following text upto the semi||colon into account and return a
+picture. We will now apply this knowledge to a more meaningful example. First we
+draw a grid.
+
+You can use the grid drawing macros to produce your own paper, for instance using
+the following mixed \TEX ||\METAFUN\ code:
+
+\typebuffer[gridpage]
+
+This produces a page (as in \in {figure} [fig:gridpage]) with a metric grid. If
+you're hooked to the inch, you can set \type {unit := 1in}. If you want to
+process this code, you need to wrap it into the normal document producing
+commands:
+
+\starttyping
+\setupcolors[state=start]
+
+\starttext
+   ... definitions ...
+\stoptext

+
+\startsection[title={Drawing functions}]
+
+Today there are powerful tools to draw functions on grids, but for simple
+functions you can comfortably use \METAPOST. Let's first draw a simple
+log||linear grid.
+
+\startbuffer[grd]
+drawoptions(withpen pencircle scaled .25pt withcolor .5white) ;
+
+draw hlingrid    (0, 20, .2, 20cm, 10cm) ;
+draw vloggrid    (0, 10, .5, 10cm, 20cm) ;
+
+drawoptions(withpen pencircle scaled .50pt) ;
+
+draw hlingrid    (0, 20,  1, 20cm, 10cm) ;
+draw vloggrid    (0, 10,  1, 10cm, 20cm) ;
+\stopbuffer
+
+\typebuffer[grd]
+
+To this grid we add some labels:
+
+\startbuffer[txt]
+fmt_pictures  := false ;    % use TeX as formatting engine
+textextoffset := ExHeight ; % a variable set by ConTeXt
+
+draw hlintext.lft(0, 20,  5, 20cm, "@3e") ;
+draw vlogtext.bot(0, 10,  9, 10cm, "@3e") ;
+\stopbuffer
+
+\typebuffer[txt]
+
+The arguments to the text placement macros are similar to the ones for drawing
+the axes. Here we provide a format string.
+
+\starttyping
+hlintext (Min, Max, Step, Length, Format)
+vlintext (Min, Max, Step, Length, Format)
+hlogtext (Min, Max, Step, Length, Format)
+vlogtext (Min, Max, Step, Length, Format)
+\stoptyping
+
+When drawing a smooth function related curve, you need to provide enough sample
+points. The \type {function} macro will generate them for you, but you need to
+make sure that for instance the maximum and minimum values are part of the
+generated series of points. Also, a smooth curve is not always the right curve.
+Therefore we provide three drawing modes:
+
+\starttabulate[|cT|l|]
+\HL
+\NC \bf method \NC \bf result                     \NC \NR
+\HL
+\NC 1 \NC a punked curve, drawn using \type {--}  \NC \NR
+\NC 2 \NC a smooth curve, drawn using \type {..}  \NC \NR
+\NC 3 \NC a tight  curve, drawn using \type {...} \NC \NR
+\HL
+\stoptabulate
+
+If method~2 or~3 do not give the desired outcome, you can try a smaller step
+combined with method~1.
+
+\startbuffer[log]
+draw
+  function(1,"log(x)","x",1,10,1) xyscaled (10cm,2cm)
+  withpen pencircle scaled 5mm withcolor transparent(1,.5,yellow) ;
+
+draw
+  function(2,".5log(x)","x",1,10,1) xyscaled (10cm,2cm)

+  {\doifmodeelse{screen}
+     {\scale[height=.85\textheight]{\processMPbuffer[grd,txt,log]}}
+     {\processMPbuffer[grd,txt,log]}}
+
+The first argument to the \type {function} macro specifies the drawing method.
+The last three arguments are the start value, end value and step. The second and
+third argument specify the function to be drawn. In this case the pairs \type
+{(x,x)} and \type {(.5log(x),x)} are calculated.

+
+drawoptions() ;
+

+     {\scale[height=.85\textheight]{\processMPbuffer[gon]}}
+     {\processMPbuffer[gon]}}
+
+In this example we draw sinus and cosine functions using degrees and radians. In
+the case of radians the end points are not calculated due to rounding errors. In
+such case you can use the \type {epsed} value, which gives slightly more
+playroom.
+
+\startbuffer[mix]
+draw function (1, "x", "sin(2x)"    , 1, 10, .01) scaled 1.5cm
+  withpen pencircle scaled 1mm withcolor transparent(1,.5,red) ;
+draw function (1, "x", "sin(2x*x)"  , 1, 10, .01) scaled 1.5cm
+  withpen pencircle scaled 1mm withcolor transparent(1,.5,green) ;
+draw function (1, "x", "sin(2x*x+x)", 1, 10, .01) scaled 1.5cm
+  withpen pencircle scaled 1mm withcolor transparent(1,.5,blue) ;
+\stopbuffer
+
+\typebuffer[mix]
+
+Of course you can do without a grid. The next example demonstrates a nice
+application of transparencies.
+
+\startlinecorrection[blank]
+\processMPbuffer[mix]
+\stoplinecorrection
+
+If we use the \type {exclusion} method for the transparencies, combined with no
+transparency, we get the following alternative.
+
+\startbuffer[mix]
+draw function (2, "x", "sin(x)" , 0, 2pi, pi/40) scaled 2cm
+  withpen pencircle scaled 5mm withcolor transparent("exclusion",1,red) ;
+draw function (2, "x", "sin(2x)", 0, 2pi, pi/40) scaled 2cm
+  withpen pencircle scaled 5mm withcolor transparent("exclusion",1,green) ;
+draw function (2, "x", "sin(3x)", 0, 2pi, pi/40) scaled 2cm
+  withpen pencircle scaled 5mm withcolor transparent("exclusion",1,blue) ;
+\stopbuffer
+
+\typebuffer[mix]
+
+\startlinecorrection[blank]
+\processMPbuffer[mix,wipe]
+\stoplinecorrection
+
+The next alternative uses a larger step, and as a result (in drawing mode~2)
+gives worse results. (Without the \type {epsed} it would have looked even worse
+in the end points.
+
+ \startbuffer[mix]
+draw function (2, "x", "sin(x)" , 0, epsed(2pi), pi/10) scaled 2cm
+  withpen pencircle scaled 5mm withcolor transparent("exclusion",1,red) ;

+  withpen pencircle scaled 5mm withcolor transparent("exclusion",1,green) ;

+
+There are enough applications out there to draw nice functions, like gnuplot for
+which Mojca Miklavec made a backend that works well with \CONTEXT. Nevertheless
+it can be illustrative to explore the possibilities of the \CONTEXT, \LUATEX,
+\METAPOST\ combination using functions.
+
+First of all you can use \LUA\ to make paths and this is used in some of the
+debugging and tracing options that come with \CONTEXT. For instance, if you
+process a document with
+
+\starttyping
+context --timing yourdoc.tex
+\stoptyping
+
+then you can afterwards process a file that is generated while processing this
+document:
+
+\starttyping
+context --extras timing yourdoc
+\stoptyping
+
+This will give you a document with graphics that show where \LUATEX\ spent its
+time on. Of course these graphics are generated with \METAPOST.
+
+There are a few helpers built in (and more might follow). For example:
+
+\startbuffer
+draw
+  \ctxlua {
+    metapost.metafun.topath {
+        { x=1, y=1 },
+        { x=1, y=3 },
+        { 4, 1},
+        "cycle"
+    }
+  }
+  xysized(4cm,3cm)
+  withpen pencircle scaled 1mm
+  withcolor .625 red ;
+\stopbuffer
+
+\typebuffer
+
+The \type {topath} function takes a table of points or strings.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+You can pass a connector so
+
+\startbuffer
+draw
+  \ctxlua {
+    metapost.metafun.topath (
+        {
+            { x=1, y=1 },
+            { x=1, y=3 },
+            { 4,   1 },
+            "cycle"
+        },
+        "--"
+    )
+  }
+  xysized(4cm,3cm)
+  withpen pencircle scaled 1mm
+  withcolor .625 red ;
+\stopbuffer
+
+\typebuffer
+
+gives:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Writing such \LUA\ functions is no big deal. For instance we have available:
+
+\starttyping
+function metapost.metafun.interpolate(f,b,e,s,c)
+    tex.write("(")
+    for i=b,e,(e-b)/s do
+        local d = loadstring (
+            string.formatters["return function(x) return %s end"](f)
+        )
+        if d then
+            d = d()
+            if i > b then
+                tex.write(c or "...")
+            end
+            tex.write(string.formatters["(%F,%F)"](i,d(i)))
+        end
+    end
+    tex.write(")")
+end
+\stoptyping
+
+An example of usage is:
+
+\startbuffer
+draw
+  \ctxlua{metapost.metafun.interpolate(
+    "math.sin(x^2+2*x+math.sqrt(math.abs(x)))",
+    -math.pi/2,math.pi/2,100
+  )}
+  xysized(6cm,3cm)
+  withpen pencircle scaled 1mm
+  withcolor .625 red ;
+\stopbuffer
+
+\typebuffer
+
+And indeed we get some drawing:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Let's see what happens when we use less accuracy and a different connector:
+
+\startbuffer
+draw
+  \ctxlua{metapost.metafun.interpolate(
+    "math.sin(x^2+2*x+math.sqrt(math.abs(x)))",
+    -math.pi/2,math.pi/2,10,"--"
+  )}
+  xysized(6cm,3cm)
+  withpen pencircle scaled 1mm
+  withcolor .625 red ;
+\stopbuffer
+
+\typebuffer
+
+Now we get:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Of course we could extend this \LUA\ function with all kind of options and we
+might even do that when we need it.

+\getbuffer[a,b]
+
+In the early days of \METAPOST\ support in \CONTEXT, Tobias Burnus asked me if it
+was possible to define English rules. What exactly does an english rule look
+like? Here is one:
+
+\EnglishRule
+
+As you can see, such a rule has to adapt itself to the current text width,
+normally \type {\hsize} in \TEX, or on request \type {\availablehsize} in
+\CONTEXT. We need to set the height to a reasonable size, related to the font
+size, and we also need to take care of proper spacing. Of course we want to run
+\METAPOST\ as less times as possible, so we need to use unique graphics. Let's
+start with the graphic.
+
+\typebuffer[a]
+
+As you can see, we pass two arguments to the graphic definition. The first
+argument is the name, the second argument is a comma separated list of variables.
+This list serves two purposes. First this list is used to create a unique profile
+for the graphic. This means that when we change the value of a variable, a new
+graphic is generated that reflects the change. A second purpose of the list is to
+convert \TEX\ data structures into \METAPOST\ ones, especially dimensions and
+colors. The graphic itself is not that spectacular. We use \type {&} because we
+don't want smooth connections.
+
+\typebuffer[b]
+
+When setting the variables, we used \type {\availablehsize}. We need to use \type
+{\noindent}, a rather familiar \TEX\ primitive, that we use here to start a non
+indented paragraph, being the graphic. The line correction is needed to get the
+spacing around the rule (graphic) right. We pass a blank skip identifier that is
+mapped to a convenient medium skip.
+
+\startbuffer[c]
+Why is this called an English line?
+
+\startnarrower
+  \EnglishRule
+    Is it because they cannot draw a straight one? This could be true
+    after a few strong beers, but then, how do Germans draw a line?
+  \EnglishRule
+\stopnarrower
+\stopbuffer
+
+\typebuffer[c]
+
+As expected, the rule adapts itself to the current width of the text. The height
+of the rule in the middle matches the height of a character with no ascenders and

+
+\in {Table} [tab:fuzzy] demonstrates how scratch numbers can be used. An
+interesting side effect is that when you look long enough to these kind of
+graphics, it looks like the lines are no longer horizontal. This table is defined
+as follows:
+
+\typebuffer
+
+You will notice that we pass a variable to the graphic using a second argument.
+We can access this variable with \type {\MPvar}. The graphic is defined as usable
+graphic, because we want to generate a unique random one each time.
+
+\typebuffer[c]
+
+The core of the macro is the \type {for} loop. Within this loop, we draw groups
+of four plus one lines. The draw path's look a bit complicated, but this has to
+do with the fact that a \type {mod} returns $0-4$ while we like to deal with
+$1-5$.
+
+The height adapts itself to the height of the line. The bounding box correction
+at the end ensures that the baseline is consistent and that the random vertical
+offsets fall below the baseline.
+
+Because we want to be sure that \type {n} has a value, we preset it by saying:
+
+\typebuffer[d]
+
+In the table, it makes sense to adapt the drawing to the lineheight, but a more
+general solution is to adapt the height to the fontsize.
+
+\starttyping
+height := 3/ 4 * \the \bodyfontsize * \currentfontscale ;
+\stoptyping
+
+\getbuffer[a]
+
+In the table we called the graphic directly, but how about making it available as
+a conversion macro? In \CONTEXT\ this is not that hard:
+
+\startbuffer
+\def\fuzzycount#1{{\tx\useMPgraphic{fuzzycount}{n=#1}}}
+\defineconversion[fuzzy][\fuzzycount]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Because such a counter should not be that large, we use \type {\tx} to switch to
+a smaller font. This also demonstrates how the graphic adapts itself to the font
+size.
+
+We can now use this conversion for instance in an itemize. To save space we use
+three columns and no white space between the lines. The \type {2*broad} directive
+makes sure that we have enough room for the number.
+
+\startbuffer

+\getbuffer
+
+\typebuffer
+
+A careful reader will have noticed that the previous definition of the fuzzy
+counter drawing is not suited to generate the graphics we started with.
+
+\typebuffer[b]
+
+This time we want to limit the width to the current \type {\hsize}. We only need
+to add a few lines of code. Watch how we don't recalculate the bounding box when
+more lines are used.

+\stopbuffer
+
+\getbuffer[def,sym]
+
+A nice application of setting up variables for a specific graphic (or class of
+graphics) is the following. In an email message the author can express his own or
+the readers expected emotions with so called smilies like: \symbol [smile]. If
+you want them in print, you can revert to combinations of characters in a font,
+but as a \TEX\ user you may want to include nicer graphics.
+
+A convenient way to implement these is to make them into symbols, one reason
+being that in that case they will adapt themselves to the current font size.
+
+\typebuffer[exa] \getbuffer[exa]
+
+Because we want an efficient implementation, we will use unique graphics, because
+these will only be generated when the circumstances change.
+
+\typebuffer[sym]
+
+The definition itself then becomes:
+
+\typebuffer[def]
+
+We can now change some characteristics of the smilies without the need to
+redefine the graphic.
+
+\startbuffer[set]
+\setupMPvariables[smile][height=1ex,color=darkred]
+\stopbuffer
+
+\typebuffer[set]

+
+In order to keep the smilies unique there is some magic involved, watch the
+second argument in the next line:
+
+\starttyping
+\startuniqueMPgraphic{smile}{type,height,color}
+\stoptyping
+
+Because unique graphics often are used in backgrounds, its uniqueness is
+determined by the overlay characteristics. In our case however the uniqueness is
+determined by the smilies type, height and color. By explicitly specifying these,
+we make sure that they count in the creation of the uniqueness stamp.
+
+\startbuffer[exa]

+
+Unfortunately it takes some effort to define graphics, attach them to an overlay,
+and invoke the background. However, the good news is that since in many cases we
+want a consistent layout, we only have to do it once. The next table has some
+hashed backgrounds. (More information about how to define tables can be found in
+the \CONTEXT\ documentation and Up||To||Date documents.)

+\getbuffer[shape-a,shape-b,shape-c]

+\placetable
+  {A hashed table.}
+  {\getbuffer}
+
+This table is defined as:
+
+\typebuffer
+
+The graphics themselves are defined in a \METAPOST\ module. In this particular
+example, the macro \type {some_hash} is defined in the file \type {mp-back.mp}.
+This macro takes six arguments:
+
+\starttyping
+some_hash (width, height, linewidth, linecolor, angle, gap) ;
+\stoptyping
+
+Because we don't want to define a specific overlay for each color and linewidth,
+we will use variables in the definition of the unique graphic.
+
+\typebuffer[shape-a]
+
+These variables are preset using \type {\setupMPvariables}:
+
+\typebuffer[shape-b]
+
+The last step in this process is to define the different
+alternatives as overlays:
+
+\typebuffer[shape-c]
+
+As we can see in the definition of the table, we can pass settings to the \type
+{\bTABLE} command. Actually, we can pass such settings to each command that
+supports backgrounds, or more precisely \type {\framed}. \in {Table} [tab:hashes]
+is for instance defined as:
+
+\startbuffer
+\bTABLE[frame=off,meta:hash:linewidth=.4pt,align=middle,offset=2ex]
+  \bTR
+    \bTD[background={meta:hash:left,meta:hash:right},
+         meta:hash:linecolor=darkyellow]
+        left        \par \& \par right    \eTD
+    \bTD[background={meta:hash:horizontal,meta:hash:vertical},
+         meta:hash:linecolor=darkred]
+         horizontal \par \& \par vertical \eTD
+  \eTR
+\eTABLE
+\stopbuffer
+
+\typebuffer
+
+The long names are somewhat cumbersome, but in that way we can prevent name
+clashes. Also, since the \METAPOST\ interface is english, the variables are also
+english.

+\startsection[title={Symbol collections}]
+
+\index{graphics+symbols}
+\index{symbols}
+
+In \CONTEXT, a symbol can be defined without much coding. The advantage of using
+symbols is that you can redefine them depending on the situation. So,
+
+\starttyping
+\definesymbol [yes] [\em Yes!]
+\stoptyping
+
+creates a symbol, that lets \type {\symbol[yes]} expand into {\em Yes!} Since
+nearly anything can be a symbol, we can also say:
+
+\starttyping
+\definesymbol [yes] [\mathematics{\star}]
+\stoptyping
+
+or even the already defined symbol \symbol[star], by saying:
+
+\starttyping
+\definesymbol [yes] [{\symbol[star]}]
+\stoptyping
+
+It may be clear that we can use a graphic as well:
+
+\typebuffer[symb-c]
+
+Since we have collected some nice buttons in a \METAPOST\ file already, we can
+use a rather simple definition:
+
+\typebuffer[symb-a]
+
+This leaves a few settings:
+
+\typebuffer[symb-b]
+
+These symbols are collected in \in {table} [tab:symbols], and are called up with
+the \CONTEXT\ commands like \type {\symbol[menu:left]}. If needed, we can collect
+these button symbols in a so called symbol set, which permits us to instantly
+switch between sets with similar symbols.

+\starttitle[title={Introduction}]
+
+This document is about \METAPOST\ and \TEX. The former is a graphic programming
+language, the latter a typographic programming language. However, in this
+document we will not focus on real programming, but more on how we can interface
+between those two languages. We will do so by using \CONTEXT, a macro package
+written in \TEX, in which support for \METAPOST\ is integrated in the core. The
+\TEX\ macros are integrated in \CONTEXT, and the \METAPOST\ macros are bundled in
+\METAFUN.
+
+When Donald Knuth wrote his typographical programming language \TEX\ he was in
+need for fonts, especially mathematical fonts. So, as a side track, he started
+writing \METAFONT, a graphical language. When you read between the lines in the
+\METAFONT\ book and the source code, the name John Hobby is mentioned alongside
+complicated formulas. It will be no surprise then, that, since he was tightly
+involved in the development of \METAFONT, after a few years his \METAPOST\ showed
+up.
+
+While its ancestor \METAFONT\ was originally targeted at designing fonts,
+\METAPOST\ is more oriented to drawing graphics as used in scientific
+publications. Since \METAFONT\ produced bitmap output, some of its operators make
+use of this fact. \METAPOST\ on the other hand produces \POSTSCRIPT\ code, which
+means that it has some features not present in \METAFONT\ and vice versa.
+
+With \METAFUN\ I will demonstrate that \METAPOST\ can also be used, or misused,
+for less technical drawing purposes. We will see that \METAPOST\ can fill in some
+gaps in \TEX, especially its lack of graphic capabilities. We will demonstrate
+that graphics can make a document more attractive, even if it is processed in a
+batch processing system like \TEX. Most of all, we will see that embedding
+\METAPOST\ definitions in the \TEX\ source enables a smooth communication between
+both programs.
+
+The best starting point for using \METAPOST\ is the manual written by its author
+John Hobby. You can find this manual at every main \TEX\ repository. Also, a copy
+of the \METAFONT\ book from Donald Knuth is worth every cent, if only because it
+will give you the feeling that many years of graphical fun lays ahead.
+
+In this \METAFUN\ manual we will demonstrate how you can embed graphics in a
+\TEX\ document, but we will also introduce most of the features of \METAPOST. For
+this reason you will see a lot of \METAPOST\ code. For sure there are better
+methods to solve problems, but I have tried to demonstrate different methods and
+techniques as much as possible.
+
+I started using \METAPOST\ long after I started using \TEX, and I never regret
+it. Although I like \TEX\ very much, I must admit that sometimes using \METAPOST\
+is even more fun. Therefore, before we start exploring both in depth, I want to
+thank their creators, Donald Knuth and John Hobby, for providing me these
+fabulous tools. Of course I also need to thank \THANH, for giving the \TEX\
+community \PDFTEX, as well as providing me the hooks I considered necessary for
+implementing some of the features presented here. In the meantime Taco Hoekwater
+has created the \METAPOST\ library so that it can be an integral component of
+\LUATEX. After that happened, the program was extended to deal with more than one
+number implementation: in addition to scaled integers we now can switch to floats
+and arbitrary precision decimal or binary calculations. I myself prototyped a
+simple but efficient \LUA\ script interface. With Luigi Scarso, who is now the
+maintainer of \METAPOST, we keep improving the system, so who knows what will
+show up next.
+
+I also want to thank David Arnold and Ton Otten for their fast proofreading, for
+providing me useful input, and for testing the examples. Without David's patience
+and help, this document would be far from perfect English and less complete.
+Without Ton's help, many small typos would have gone unnoticed.
+
+In the second version of this manual the content was been adapted to \CONTEXT\
+\MKIV\ that uses \LUATEX\ and the built in \METAPOST\ library. In the meantime
+some \LUA\ has been brought into the game, not only to help construct graphics,
+but also as a communication channel. In the process some extra features have been
+added and some interfacing has been upgraded. The third version of this document
+deals with that too. It makes no sense to maintain compatibility with \CONTEXT\
+\MKII, but many examples can be used there as well. In the meantime most
+\CONTEXT\ users have switched to \MKIV, so this is no real issue. In the fourth
+update some new features are presented and the discussion of obsolete ones have
+been removed.
+
+The fifth update describes the \MPIV\ version of \METAFUN\ which brings some more
+and improved functionality. Some examples are inspired from questions by users and
+examples that Alan Braslau, Luigi Scarso and I made when testing new features and
+macros. Some examples can be rewritten in a more efficient way but are kept as
+they are. Therefore this manual presents different ways to solve problems.
+Hopefully this is not too confusing. Numerous examples can be found in the other
+manuals and test suite.

+\startchapter[title={Enhancing the layout}]
+
+\startintro
+
+One of the most powerful and flexible commands of \CONTEXT\ is \type {\framed}.
+We can use the background features of this command to invoke and position
+graphics that adapt themselves to the current situation. Once understood,
+overlays will become a natural part of the \CONTEXT\ users toolkit.
+
+\stopintro
+
+\startsection[title={Overlays}]
+
+\index{overlays}
+
+Many \CONTEXT\ commands support overlays. The term {\em overlay} is a bit
+confusing, since such an overlay in most cases will lay under the text. However,
+because there can be many layers on top of each other, the term suits its
+purpose.
+
+When we want to put a \METAPOST\ graphic under some text, we go through a three
+step process. First we define the graphic itself:
+
+\startbuffer
+\startuniqueMPgraphic{demo circle}
+  path p ;
+  p := fullcircle xscaled \overlaywidth yscaled \overlayheight ;
+  fill p withcolor .85white ;
+  draw p withpen pencircle scaled 2pt withcolor .625red ;
+\stopuniqueMPgraphic
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+This graphic will adapt itself to the width and height of the overlay. Both \type
+{\overlaywidth} and \type {\overlayheight} are macros that return a dimension
+followed by a space. The next step is to register this graphic as an overlay.
+
+\startbuffer
+\defineoverlay[demo circle][\uniqueMPgraphic{demo circle}]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer

+
+In this case, it would have made sense to either set the \type {offset} to a

+is positioned outside the frame.
+
+The difference between the three offsets \type {offset}, \type {frameoffset} and
+\type {backgroundoffset} is demonstrated in \in {figure} [fig:offsets]. While the
+\type {offset} is added to the (natural or specified) dimensions of the content
+of the box, the other two are applied to the frame and background and don't add
+to the dimensions.
+
+In the first row we only set the \type {offset}, while in the second row, the
+(text) offset is set to \type {3pt}. When not specified, the \type {offset} has a
+comfortable default value of \type {.25ex} (some 25\% of the height of an~x).

+As the first row in \in {figure} [fig:offsets] demonstrates, instead of a value,
+one can pass a keyword. The \type {overlay} keyword implies that there is no
+offset at all and that the lines cover the content. With \type {none} the frame
+is drawn tight around the content. When the offset is set to \type {0pt} or more,
+the text is automatically set to at least the height of a line. You can turn this
+feature off by saying \type {strut=off}. More details can be found in the
+\CONTEXT\ manual.
+
+In \in {figure} [fig:all offsets] we have set {offset} to \type {3pt}, \type
+{frameoffset} to \type {6pt} and \type {backgroundoffset} to \type {9pt}. Both
+the frame and background offset are sort of imaginary, since they don't

+I have run into people who consider it kind of strange when you want to use \TEX\

+section with your eyes closed.
+
+One of the \CONTEXT\ presentation styles (number 15, tagged as balls) stepwise
+builds screens full of sentences, quotes or concepts, packages in balloons and
+typesets them as a paragraph. We will demonstrate that \TEX\ can typeset graphics
+using the following statement.
+
+% \let\processword\relax
+
+\startbuffer[lions]
+\processwords{As you may know, \TEX's ambassador is a lion, while {\METAFONT}
+is represented by a lioness. It is still unclear if they have a relationship,
+but if so, and if a cub is born, may it enjoy \METAFUN.}
+\stopbuffer
+
+\startquotation
+\def\processwords#1{#1}\getbuffer[lions]
+\stopquotation
+
+The low level \CONTEXT\ macro \type {\processwords} provides a mechanism to treat
+the individual words of its argument. The macro is called as follows:
+
+\typebuffer[lions]
+
+In order to perform a task, you should also define a macro \type {\processword},
+which takes one argument. The previous quote was typeset with the following
+definition in place:
+
+\starttyping
+\def\processword#1{#1}
+\stoptyping
+
+A slightly more complicated definition is the following:

+\startbuffer
+\def\processword#1{\noindent\framed{#1}\space}

+We now get:

+
+The \type {broad} increases the raggedness. We defined three different graphics
+(a, b and c) because we want some to be unique, which saves some processing. Of
+course we don't reuse the random graphics. In the definition of \type
+{\processword} we have to use \type {\noindent} because otherwise \TEX\ will put
+each graphic on a line of its own. Watch the space at the end of the macro.
+
+\stopsection
+
+\startsection[title={Graphics and macros}]
+
+Because \TEX's typographic engine and \METAPOST's graphic engine are separated,
+interfacing between them is not as natural as you may expect. In \CONTEXT\ we
+have tried to integrate them as much as possible, but using the interface is not
+always as convenient as it should be. What method you follow, depends on the
+problem at hand.
+
+The official \METAPOST\ way to embed \TEX\ code into graphics is to use \typ
+{btex ... etex}. As soon as \CONTEXT\ writes the graphic data to the intermediate
+\METAPOST\ file, it looks for these commands. When it has encountered an \type
+{etex}, \CONTEXT\ will make sure that the text that is to be typeset by \TEX\ is
+{\em not} expanded. This is what you may expect, because when you would embed
+those commands in a stand||alone graphic, they would also not be expanded, if
+only because \METAPOST\ does not know \TEX. With expansion we mean that \TEX\
+commands are replaced by their meaning (which can be quite extensive).
+
+{\em Users of \CONTEXT\ MKIV\ can skip the next paragraph}.
+
+When \METAPOST\ sees a \type {btex} command, it will consult a so called \type
+{mpx} file. This file holds the \METAPOST\ representation of the text typeset by
+\TEX. Before \METAPOST\ processes a graphic definition file, it first calls
+another program that filters the \type {btex} commands from the source file, and
+generates a \TEX\ file from them. This file is then processed by \TEX, and after
+that converted to a \type {mpx} file. In \CONTEXT\ we let \TEXEXEC\ take care of
+this whole process.
+
+Because the \typ {btex ... etex} commands are filtered from the raw \METAPOST\
+source code, they cannot be part of macro definitions and loop constructs. When
+used that way, only one instance would be found, while in practice multiple
+instances may occur.
+
+This drawback is overcome by \METAFUN's \type {textext} command. This command
+still uses \typ {btex ... etex} but writes these commands to a separate job
+related file each time it is used. \footnote {It took the author a while to find
+out that there is a \METAPOST\ module called \type {tex.mp} that provides a
+similar feature, but with the disadvantage that each text results in a call to
+\TEX. Each text goes into a temporary file, which is then included and results in
+\METAPOST\ triggering \TEX.} After the first \METAPOST\ run, this file is merged
+with the original file, and \METAPOST\ is called again. So, at the cost of an
+additional run, we can use text typeset by \TEX\ in a more versatile way. Because
+\METAPOST\ runs are much faster than \TEX\ runs, the price to pay in terms of run
+time is acceptable. Unlike \typ {btex ... etex}, the \TEX\ code in \type
+{textext} command is expanded, but as long as \CONTEXT\ is used this is seldom a
+problem, because most commands are somewhat protected.
+
+If we define a graphic with text to be typeset by \TEX, there is a good chance
+that this text is not frozen but passes as argument. A \TEX||like solution for
+passing arbitrary content to such a graphic is the following: \footnote {The \type
+{\unexpanded} prefix makes the command robust for being passed as argument. It is not
+to be confused with the primitive. We had this feature already when the primitive
+showed up and it was considered to be inconvenient for other macro packages to adapt to
+the \CONTEXT\ situation. So keep that in mind when you mix macro packages.}

+\stoplinecorrection
+
+In \CONTEXT\ we seldom pass settings like the angle of rotation in this manner.
+You can use \type {\setupMPvariables} to set up graphic||specific variables. Such
+a variable can be accessed with \type {\MPvar}.

+\startbuffer[def]

+\stopbuffer
+

+In a similar fashion we can isolate the text. This permits us to use the same

+  draw \MPbetex{RotatedText} rotated \MPvar{rotation} ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer[def] \getbuffer[def]
+
+Again, we default to a 90 degrees rotation, and pass both the settings and text
+in an indirect way. This method permits you to build complicated graphics and
+still keep macros readable.

+
+You may wonder why we don't use the variable mechanism to pass the text. The main
+reason is that the text mechanism offers a few more features, one of which is
+that it passes the text straight on, without the danger of unwanted expansion of
+embedded macros. Using \type {\setMPtext} also permits you to separate \TEX\ and
+\METAPOST\ code and reuse it multiple times (imagine using the same graphic in a
+section head command).
+
+There are three ways to access a text defined with \type {\setMPtext}. Imagine
+that we have the following definitions:

+\setMPtext {2} {See what happens here.}

+The \type {\MPbetex} macro returns a \typ {btex ... etex} construct. The \type

+this spread, we could have enlarged the frame on both sides.

+In the previous graphic we calculated the big rectangle taking the small one into

+Because we use a random graphic, we cannot guarantee beforehand that the left and

+baseline, being the lowest one of a pair of lines, in such a way that it suits
+the proportions of the line as specified by the strut. A strut is an imaginary
+large character with no width. You should be aware of the fact that while \TEX\

+\index{\LUA}
+
+\startintro
+
+Already for some years I have been wondering how it would be if we could escape
+to \LUA\ inside \METAPOST, or in practice, use \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 often it 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.
+
+\stopintro
+
+\startsection[title=Introduction]
+
+\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
+back strings into the \TEX\ input stream. There a complication is that 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 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 darkred ;
+\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()") ;
+) withcolor darkyellow withpen pencircle scaled 1 ;
+draw textext(lua("mp.print(statistics.elapsedtime())"))
+    ysized 50 withcolor darkred ;
+\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 next 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 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. With \LUAJITTEX\ generating the graphic takes 15\% less time.
+
+\startbuffer
+numeric n ; n := lua("mp.print(1) mp.print('+') mp.print(2)") ;
+draw textext(n) xsized 1cm withcolor darkred ;
+\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 darkred ;
+\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 darkred ;
+\stopbuffer
+
+\typebuffer
+
+This typesets \processMPbuffer. Watch 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 darkred ;
+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 darkred ;
+    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 darkred ;
+    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 darkred ;
+    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 ok in \type {double} mode, which makes
+much sense when processing data from other sources. Watch 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 darkred ;
+    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 darkred ;
+\stopbuffer
+
+\typebuffer
+
+In double mode you will get zero printed but in scaled mode we definitely get a
+difference:
+
+\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 darkred ;
+\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.

+\startsection[title=The library]
+
+In \CONTEXT\ we have a dedicated runner, but for the record we mention the
+low level constructor:
+
+\starttyping
+local m = mplib.new {
+    ...
+    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
+the helpers in the library.
+
+\starttabulate[|l|l|]
+\HL
+\NC \type {m:get_numeric(name)}       \NC returns a numeric (double) \NC \NR
+\NC \type {m:get_boolean(name)}       \NC returns a boolean (\type {true} or \type {false}) \NC \NR
+\NC \type {m:get_string (name)}       \NC returns a string \NC \NR
+\HL
+\NC \type {mplib.get_numeric(m,name)} \NC returns a numeric (double) \NC \NR
+\NC \type {mplib.get_boolean(m,name)} \NC returns a boolean (\type {true} or \type {false}) \NC \NR
+\NC \type {mplib.get_string (m,name)} \NC returns a string \NC \NR
+\HL
+\stoptabulate
+
+In \CONTEXT\ the instances are hidden and wrapped in high level macros, so there
+you cannot use these commands.
+
+\stopsection
+
+\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)}
+    \type {pair(t)}                   \NC returns a proper pair \NC \NR
+\NC \type {triplet(x,y,z)}
+    \type {triplet(t)}                \NC returns an \RGB\ color \NC \NR
+\NC \type {quadruple(w,x,y,z)}
+    \type {quadruple(t)}              \NC returns an \CMYK\ color \NC \NR
+\NC \type {format(fmt,...)}           \NC returns a formatted string \NC \NR
+\NC \type {quoted(fmt,...)}
+    \type {quoted(s)}                 \NC returns a (formatted) quoted string  \NC \NR
+\NC \type {path(t[,connect][,close])} \NC returns a connected (closed) path \NC \NR
+\HL
+\stoptabulate
+
+The \type {mp.get} namespace provides the following helpers:
+
+\starttabulate[|l|l|]
+\HL
+\NC \type {numeric(name)}      \NC gets a numeric from \METAPOST \NC \NR
+\NC \type {boolean(name)}      \NC gets a boolean from \METAPOST \NC \NR
+\NC \type {string(name)}       \NC gets a string from \METAPOST \NC \NR
+\HL
+\stoptabulate
+
+\stopsection
+
+\startsection[title=Paths]
+
+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've put the data in a buffer so that it can be shown
+here as well as used in a demo. Watch 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-.25ExHeight,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 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
+
+A variant call is the following: \footnote {Getting that to work properly in the
+library was non||trivial as the loop variable \type {i} is an abstract nameless
+variable at the \METAPOST\ end. When investigating this Luigi Scarso and I found out
+that the internals of \METAPOST\ are not really geared for interfacing this way
+but in the end it worked out well.}
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.size(MP.myset)") :
+    fill area
+      lua("mp.path(MP.myset[mp.get.numeric('i')])")
+      xysized (HSize,5ExHeight)
+      withcolor basiccolors[i]/2
+      withtransparency (2,.25) ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+The result is the same:
+
+\startlinecorrection[blank] \getbuffer \stoplinecorrection
+
+\startbuffer
+\startluacode
+  MP.mypath = function(i)
+    return mp.path(MP.myset[mp.get.numeric(i)])
+  end
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua("mp.size(MP.myset)") :
+    fill area
+      lua("MP.mypath('i')")
+      xysized (HSize,5ExHeight)
+      withcolor basiccolors[i]/2
+      withtransparency (2,.25) ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+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
+
+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.
+
+\startbuffer
+\startMPcode
+  for i=1 upto lua.MP.dataset.Size() :
+    path p ; p :=
+      lua.MP.dataset.Line(i)
+      xysized (HSize-ExHeight,20ExHeight) ;
+    draw
+      p
+      withpen pencircle scaled .25ExHeight
+      withcolor basiccolors[i]/2 ;
+    drawpoints
+      p
+      withpen pencircle scaled ExHeight
+      withcolor basiccolors[i]/2 ;
+  endfor ;
+\stopMPcode
+\stopbuffer
+
+\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 the once 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-.25ExHeight,10ExHeight)
+    withpen pencircle scaled .25ExHeight
+    withcolor darkyellow ;
+  fill area
+    lua.mp.datasets.bar.Line()
+    xysized (HSize/2-EmWidth-.25ExHeight,10ExHeight)
+    shifted (HSize/2+EmWidth,0)
+    withpen pencircle scaled .25ExHeight
+    withcolor darkred ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+Because the datasets are stores 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 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 In order avoid interference with suffix handling in \METAPOST\ the methods
+start with an uppercase character.}
+
+\stopsection
+
+\startsection[title=Passing variables]
+
+You can pass variables from \METAPOST\ to \CONTEXT. Originally that happened via
+a temporary file and so called \METAPOST\ specials. Nowadays it's done via \LUA.
+Here is an example:
+
+\startbuffer
+\startMPcalculation
+
+passvariable("version","1.0") ;
+passvariable("number",123) ;
+passvariable("string","whatever") ;
+passvariable("point",(1.5,2.8)) ;
+passvariable("triplet",(1/1,1/2,1/3)) ;
+passvariable("quad",(1.1,2.2,3.3,4.4)) ;
+passvariable("boolean",false) ;
+passvariable("path",fullcircle scaled 1cm) ;
+path p[] ; p[1] := fullcircle ; p[2] := fullsquare ;
+passarrayvariable("list",p,1,2,1) ; % first last step
+\stopMPcalculation
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We can visualize the result with
+
+\startbuffer
+\startluacode
+context.tocontext(metapost.variables)
+\stopluacode
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+In \TEX\ you can access these variables as follows:
+
+\startbuffer
+\MPrunvar{version}
+\MPruntab{quad}{3}
+(\MPrunset{triplet}{,})
+
+$(x,y) = (\MPruntab{point}{1},\MPruntab{point}{2})$
+$(x,y) = (\MPrunset{point}{,})$
+\stopbuffer
+
+\typebuffer
+
+This becomes: % we need a hack as we cross pages and variables get replace then
+
+\startlines
+\getbuffer
+\stoplines
+
+Here we passed the code between \type {\startMPcalculation} and \type
+{\stopMPcalculation} which does not produce a graphic and therefore takes no
+space in the flow. Of course it also works with normal graphics.
+
+\startbuffer
+\startMPcode
+path p ; p := fullcircle xyscaled (10cm,2cm) ;
+path b ; b := boundingbox p ;
+startpassingvariable("mypath")
+    passvariable("points",p) ;
+    startpassingvariable("metadata")
+        passvariable("boundingbox",boundingbox p) ;
+    stoppassingvariable ;
+stoppassingvariable ;
+fill p withcolor .625red ;
+draw b withcolor .625yellow ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+    \getbuffer
+\stoplinecorrection
+
+This time we get:
+
+\ctxlua{context.tocontext(metapost.variables)}
+
+You need to be aware of the fact that a next graphic resets the previous
+variables. You can easily overcome that limitation by saving the variables (in
+\LUA). It helps that when a page is being shipped out (which can involve
+graphics) the variables are protected. You can push and pop variable sets with
+\type {\MPpushvariables} and \type {\MPpopvariables}. Because you can nest
+the \type {start}||\type{stop} pairs you can create quite complex indexed
+and hashed tables. If the results are not what you expect, you can enable a
+tracker to follow what gets passed:
+
+\starttyping
+\enabletrackers[metapost.variables]
+\stoptyping
+
+Serializing variables can be done with the \type {tostring} macro, for instance:
+
+\startbuffer
+\startMPcode
+message("doing circle",fullcircle);
+draw fullcircle ;
+\stopMPcode
+\stopbuffer
+
+In this case the \type {tostring} is redundant as the message already does the
+serialization.

+\startchapter[title={\METAFUN\ macros}]
+
+\index{metafun}
+
+\startintro
+
+\CONTEXT\ comes with a series of \METAPOST\ modules. In this chapter we will
+summarize the most important \TEX\ and \METAPOST\ macros. More information can be
+found in the documentation of the modules.
+
+\stopintro
+
+There are several ways to use the power of \METAFUN, either or not using
+\CONTEXT.
+
+\startitemize[n]
+
+\startitem
+    You can create an independent \type {mp} file and process it with the
+    \METAPOST\ program or \MPTOPDF. Depending on what features you use, the
+    succes of a run depends on the proper set up of the programs that take care
+    of running \TEX\ for \type {btex}.
+\stopitem
+
+\startitem
+    You can embed the graphic in a \type {\startMPpage} construct and process it
+    with \CONTEXT\ \MKIV. In that case you have the full \METAFUN\ functionality
+    available. If for some reason you still want to use \MKII, you need to use
+    \TEXEXEC\ as before processing the file, it will do a couple of checks on the
+    file. It will also make sure that the temporary files (\type {mpt} for \type
+    {textext}'s and \type {mpo} for outline fonts) are taken care of too.
+\stopitem
+
+\startitem
+    You can integrate the graphic in the document flow, using buffers, \METAPOST\
+    code sections, or (reusable) graphic containers. In that case the graphics
+    are processed runtime or between runs. This happens automatically.
+\stopitem
+
+\stopitemize
+
+Unless you want to write low level \CONTEXT\ code yourself, there is no real
+reason to look into the modules that deal with \METAPOST\ support. The
+traditional (partly generic) code is collected in:
+
+\starttabulate[|lT|p|]
+\NC supp-mps.tex \NC low level inclusion macros and housekeeping \NC\NR
+\NC supp-mpe.tex \NC experimental extensions (like specials)     \NC\NR
+\NC supp-pdf.tex \NC \METAPOST\ to \PDF\ conversion              \NC\NR
+\stoptabulate
+
+Especially the last two can be used in other macro packages. However, in
+\CONTEXT\ we have regrouped the code (plus more) in other files:
+
+\starttabulate[|lT|p|]
+\NC meta-***.tex \NC definition and managing   \NC\NR
+\NC mlib-***.tex \NC processing and conversion \NC\NR
+\stoptabulate
+
+The last category will certainly grow. Some of these modules are preloaded,
+others can be loaded using the command \type {\useMPlibrary}, like
+
+\starttyping
+\useMPlibrary[clp,txt]
+\stoptyping
+
+for loading the predefined clipping paths and text tricks.
+
+The \METAPOST\ code is organized in files named \type {mp-****.mp}. The core file
+is \type {mp-tool.mp} and this file can comfortably be used in stand||alone
+graphics. The file \type {metafun.mp} is used to load the collection of modules
+into a format. The collection of \METAPOST\ code files will grow in due time, but
+as long as you use the \METAFUN\ format, you don't have to keep track of the
+organization of files. Most files relate to subsystems and are loaded
+automatically, like the files that implement page layout support and flow charts.

+
+\startintro
+
+In this chapter, we will explore one of the more advanced, but also conceptually
+more difficult, graphic capabilities of \CONTEXT. It took quite a few experiments
+to find the {\em right} way to support these kind of graphics, and you can be
+sure that in due time extensions will show up. You can skip this chapter if you
+are no \CONTEXT\ user. Because we're now a decade into \MKIV\ the tricks here
+will assume that you use \CONTEXT\ \MKIV\ because we have a more convenient
+interface there. For old|-|school \MKII\ usage you can look in old \METAFUN\
+manuals or in the \type {mkii} source files. Of course we remain compatible, it's
+just that more (convenient) interfaces were added.
+
+\stopintro
+
+\startsection[title={The status quo}]
+
+After \TEX\ has read a paragraph of text, it will try to break this paragraph
+into lines. When this is done, the result is flushed and after that \TEX\ will
+check if a page should be split off. As a result, we can hardly predict how a
+document will come out. Therefore, when we want graphics to adapt themselves to
+this text, maybe even to text broken across lines, we have to deal with this
+asynchronous feature of \TEX\ in a rather advanced way. Before we present a way
+of dealing with this complexity, we will elaborate on the nature of embedded
+graphics in \TEX.
+
+When \TEX\ entered the world of typesetting, desktop printers were not that
+common, let alone color desktop printers. But times have changed and nowadays we
+want color and graphics and if possible we want them integrated in the text. When
+\METAPOST\ showed up it depended on the \DVI\ processor to recognize the
+\POSTSCRIPT\ code as being produced by \METAPOST\ and therefore also include the
+fonts that were used. But color was still limited to \RGB. When \PDFTEX\ evolved
+I wrote an interpreter (in \TEX) that could translate the output to \PDF. This
+also opened up the possibility to add features to \METAPOST, like \CMYK\ colors,
+shading, transparencies etc. But basically the \TEX\ and \METAPOST\ processes
+were rather isolated. We could of course pass information to \METAPOST\ and pick
+up information from \METAPOST\ in a second pass. That has changed in \LUATEX.
+
+In order to really integrate \METAPOST\ graphics into the flow you need to know
+where you are on the page and how large graphics should be, especially when you
+want them to depend on the layout. A first solution to this was to embed specials
+in the \DVI\ that could later be used to extract positions. In retrospect this
+was a relative trivial extension, something that could have been around much
+earlier but somehow didn't happen. Anyhow, after some experiments \PDFTEX\ got a
+native position tracker which meant that no post processor was needed. Of course
+\LUATEX\ inherited this feature too. Because positioning is rather bound to the
+macro package reading this chapter only makes sense when you use \CONTEXT.

+\index {graphics+positioning}
+\index {positioning}
+\index {anchoring}
+
+Because we have a \LUA\ connection in \MPLIB, we have implemented a couple of
+helpers that make live easier. This is also why the following examples are \MKIV\
+specific, although \MKII\ can do the same, but with a bit different set of
+helpers. We can for instance query properties of \hpos {A-0} {positions} without
+using \TEX\ macros but can use \METAPOST\ macros instead. Let's give an example.
+The background and frame behind the word \type {position} in this paragraph is
+not done with \type {\framed} but using a different mechanism:
+
+\starttyping
+to get \hpos {A-0} {positions} sorted
+\stoptyping
+
+The \type {\hpos} refers to a position and we have bound that position to a graphic:
+
+\starttyping
+\setMPpositiongraphic{A-0}{mpos:box}{self=A-0}
+\stoptyping
+
+The graphic itself is defined with:
+
+\typebuffer[box:1]
+
+A variant that has no macro calls and does all via the \LUA\ intercaface in \MKIV\ is
+the following:
+
+\typebuffer[box:1:also]
+
+A \type {\hpos} position has several properties: the coordinates of the origin:
+\type {x} and \type {y}, the dimensions of the boxed content, \type {w}, \type
+{h} and \type {d}, and the page number \type {p}. An additional helper \type
+{positioninregion} will move the drawing to the right spot in the region.
+Examples or regions are the page, text area or some overlay. The \type
+{positionatanchor} variant relocates to the anchor of the given tag. The first
+helper is actually a shortcut for:
+
+\starttyping
+currentpicture := currentpicture shifted - positionxy(positionanchor) ;
+\stoptyping
+
+In our case we use a dedicated layer \type {backgraphics} that we have hooked into
+the page backgrounds:
+
+\starttyping
+\setupbackgrounds
+  [page]
+  [background={backgraphics,foreground,foregraphics}]
+
+\defineoverlay [backgraphics] [\positionoverlay{backgraphics}]
+\defineoverlay [foregraphics] [\positionoverlay{foregraphics}]
+\stoptyping
+
+The relation between position graphics and that layer are defined as follows
+(we will come back to this in a moment):
+
+\typebuffer[box:2]
+
+\stopsection
+
+\startsection[title={A more detailed view}]
+
+As we know, a decent portion of \TEX's attention is focused on breaking
+paragraphs into lines and determining the optimal point to split off the page.
+Trying to locate the optimal points to break lines is a dynamic process. The
+space between words is flexible and we don't know in advance when a \hpos {A-1}
+{word} or piece of a word |<|maybe it's best to talk of typographic \hpos {A-2}
+{globs} instead|>| will end up on the page. It might even cross the page
+boundary.
+
+In the previous section we saw \hpos {A-3} {word} and \hpos {A-4} {globs}
+encircled and connected by an arrow. This graphic can be drawn only when the
+position and dimensions are known. Unfortunately, this information is only
+available after the paragraph is typeset and the best breakpoints are chosen.
+\bpos {A-5} Because the text must be laid on top of the graphic, the graphic must
+precede the first word in the typeset stream or it must be positioned on a
+separate layer. In the latter case it can be calculated directly after the
+paragraph is typeset, but in the former case a second pass is needed. \epos {A-5}
+Because such graphics are not bound to one paragraph, the multi||pass option
+suits better because it gives us more control: the more we know about he final
+state, the better we can act upon it. Think of graphics on the first page that
+depend on the content of the last page \bpos {A-6} or, as in this paragraph,
+backgrounds that depend on the typeset text. \epos {A-6}
+
+The arrows that connect the shapes are drawn with the following code that now
+looks familiar:
+
+\typebuffer[arrow:1]
+
+and
+
+\typebuffer[arrow:2]
+
+However, here we anchor at one of the positions because we don't flush in a layer
+but at the position itself. Indeed it looks complex.
+
+It may be clear now that we need some positional information in order to provide
+features like the ones shown here. The fact that we will act upon in a second
+pass simplifies the task, although it forces us to store the positional
+information between runs in some place. This may look uncomfortable at first
+sight, but it also enables us to store some additional information. Now why is
+that needed?
+
+A position has no dimensions, it's just a place somewhere on the page. In order
+to do tricks like those shown here, we also need to know the height and depth of
+lines at a specific point as well as the width of the box(es) we're dealing with.
+In the encircled examples, the dimensions of the box following the positional
+node are stored along with the position.
+
+In order to process the graphics, we tag each point with a name, so that we can
+attach actions to those points. In fact they become trigger points. As we will
+demonstrate, we also need to store the current page number. This brings the data
+stored with a point to:
+
+\starttyping
+<identifier> <pagenumber> <x> <y> <width> <height> <depth>
+\stoptyping
+
+Actually we store more information, for example the region in which the positions
+sit. Depending on the use we can also get access to paragraph and line properties
+but discussing these is beyond this manual. These are for instance used in the
+text backgrounds.
+
+The page number is needed in order to let the graphics engine determine boundary
+conditions. Backgrounds like those shown here can span multiple pages. In order
+to calculate the right backgrounds, some additional information must be
+available, like the top and bottom of the current text area. In fact, these are
+just normal points that can be saved while processing the split off page. So,
+apart from positioning anchors in the text we need anchors on crucial points of
+the layout. This means that this kind of support cannot be fully integrated into
+the \TEX\ kernel, unless we also add extensive support for layout definitions,
+and that is probably not what we want.
+
+As soon as something like $(x,y)$ shows up, a logical question is where $(0,0)$
+is located. Although this is a valid question, the answer is less important than
+you may expect. Even if we know that ($0,0)$ is \quote {officially} located in
+the bottom left corner of the page, the simple fact that in \CONTEXT\ we are
+dealing with a mixed page concept, like paper size and print paper size, or left
+and right pages, forces us to think in relative positions instead of absolute
+ones. Therefore, graphics, even those that involve multiple positions, are
+anchored to a position on the layer on which they are located.
+
+Users who simply want to use these features may wonder why we go into so much
+detail. The main reason is that in the end many users will want to go beyond the
+simple cases, and when dealing with these issues, you must be aware not only of
+height, depth and width, but also of the crossing of a page boundary, and the
+height and depth of lines. In some cases your graphics may have to respond to
+layout characteristics, like differences between odd and even pages. Given that
+unique identifiers are used for anchor points, in \CONTEXT\ you can have access
+to all the information needed. Here are some of the helpers:
+
+\starttabulate[|T||]
+\NC positionpath  (tag) \NC the path determined by width, height and depth \NC \NR
+\NC positionxy    (tag) \NC the origin \NC \NR
+\NC positionwhd   (tag) \NC the dimensions (in a triplet) \NC \NR
+\NC positionpage  (tag) \NC the page number fo the position \NC \NR
+\NC positionregion(tag) \NC the region that the position sits in \NC \NR
+\NC positionbox   (tag) \NC the positioned box (path shifted over coordinates) \NC \NR
+\NC positionanchor      \NC the current anchor of the region \NC \NR
+\stoptabulate
+
+The \type {positionwhd} macro returns a triplet that you can query, like:
+
+\starttyping
+triplet whd ; whd := positionwhd("\MPvar{from}");
+numeric wd; wd := wdpart whd ;
+\stoptyping
+
+We will add more such convenient helpers in the future. In the \CONTEXT\
+distribution you can find examples (in manuals or librarties) that demonstrate
+other tricks with positioning.

+\stopbuffer
+
+\startbuffer[b]
+In a previous section we saw that some \hpos {X-1} {words} were
+\hpos {X-2} {circled} and connected by an \hpos {X-3} {arrow}.
+As with most things in \CONTEXT, marking these words is separated
+from declaring what to do with those words. This paragraph is keyed
+in as:
+\stopbuffer
+
+\getbuffer[a,b]
+
+\typebuffer[b]
+
+We see three position anchors, each marked by an identifier: \type {X-1}, \type
+{X-2} and \type {X-3}. Each of these anchors can be associated with a (series) of
+graphic operations. Here we defined:
+
+\typebuffer[a]
+
+These examples clearly demonstrate that we cannot control to what extent graphics
+will cover text and vice versa. A solution to this problem is using position
+overlays. We can define such an overlay as follows:
+
+\startbuffer
+\startpositionoverlay{backgraphics}
+  \setMPpositiongraphic{G-1}{mypos:circle}
+  \setMPpositiongraphic{G-2}{mypos:circle}
+  \setMPpositiongraphic{G-3}{mypos:circle}
+  \setMPpositiongraphic{G-4}{mypos:circle}
+\stoppositionoverlay
+
+\startpositionoverlay{foregraphics}
+  \setMPpositiongraphic{G-1}{mypos:line}{to=G-2}
+  \setMPpositiongraphic{G-2}{mypos:line}{to=G-3}
+  \setMPpositiongraphic{G-3}{mypos:line}{to=G-4}
+\stoppositionoverlay
+\stopbuffer
+
+\getbuffer \typebuffer
+
+\startbuffer
+First we have defined an \hpos {G-1} {\strut overlay}. This
+overlay can be attached to some overlay layer, like, in our
+case, the \hpos {G-2} {\strut page}. We define four small \hpos
+{G-3} {\strut circles}. These are drawn as soon as the page
+overlay is typeset. Because they are located in the
+background, they don't cover the \hpos {G-4} {\strut text}, while
+the lines do. The previous paragraph was typeset by saying:
+\stopbuffer
+
+\getbuffer \typebuffer
+
+As said, the circles are on the background layer, but the lines are not! They are
+positioned on top of the text. This is a direct result of the definition of the
+page background:
+
+\starttyping
+\defineoverlay [foregraphics] [\positionoverlay{foregraphics}]
+\defineoverlay [backgraphics] [\positionoverlay{backgraphics}]
+
+\setupbackgrounds
+  [page]
+  [background={backgraphics,foreground,foregraphics}]
+\stoptyping
+
+\doifmode{screen}{\writestatus{CHECK}{POSITION GRAPHICS}}
+
+In this definition, the predefined overlay \type {foreground} inserts the page
+data itself, so the foreground graphics end up on top. This example also
+demonstrates that you should be well aware of the way \CONTEXT\ builds a page.
+There are six main layers, in some cases with sublayers. The body text goes into
+the main text layer, which, unless forced otherwise, lays on top.
+
+\startitemize[packed,n,columns,three]
+\item  paper background
+\item  area backgrounds
+\item  page backgrounds
+\item  text areas
+\item  logo areas
+\item  main text
+\stopitemize
+
+The paper background is used for special (sometimes internal) purposes. There are
+three page backgrounds: left, right and both. The text areas, logo areas and
+backgrounds form a $5 \times 5$ matrix with columns containing the leftedge,
+leftmargin, text, rightmargin, and rightedge. The rows of the matrix contain the
+top, header, text, footer, and bottom. The main text is what you are reading now.
+
+Since the page background is applied last, the previous layers can be considered
+to be the foreground to the page background layer. And, indeed, it is available
+as an overlay under the name \type {foreground}, as we already saw in the
+example. Foregrounds are available in most cases, but (for the moment) not when
+we are dealing with the text area. Since anchoring the graphics is implemented
+rather independent of the position of the graphics themselves, this is no real
+problem, we can put them all on the page layer, if needed in separate overlays.
+
+How is such a graphic defined? In fact these graphics are a special case of the
+already present mechanism of including \METAPOST\ graphics. The circles are
+defined as follows:
+
+\typebuffer[g-circle]
+
+Drawing the lines is handled in a similar fashion.
+
+\typebuffer[g-line]
+
+The command \tex {startMPpositiongraphic} defines a graphic, in this example we
+have called it \type {mypos:circle}. Here we show the definition out of order but
+normally you need to define it before you refer to it.
+
+The \METAPOST\ macro \type {positionbox} returns a box that is constructed from
+the coordinates and dimensions. After this call, the corners are available via
+\type {llcorner}, \type {lrcorner}, \type {urcorner} and \type {ulcorner}. The
+center is accessible by \type {center}. When we are finished drawing the graphic,
+we can anchor the result with \type {positioninregion}. This macro automatically
+handles positioning on specific layers. The helper macros are not loaded by
+default, you do that with:
+
+\typebuffer[g-include]
+
+The position macro \type {\MPpos} returns the current characteristics of a
+position. The previously defined G~positions return:

+
+The numbers represent the real pagenumber~$p$, the current position $(x,y)$, and
+the dimensions of the box $(w,h,d)$ if known. These values are fed directly into
+\METAPOST\ graphics but the individual components can be asked for by \type
+{\MPp}, \type {\MPx}, \type {\MPy}, \type {\MPw}, \type {\MPh} and \type {\MPd}.
+
+In the previous definition of the graphic, we saw another macro, \type {\MPvar}.
+When we invoke a graphic or attach a graphic to a layer, we can pass variables.
+We can also set specific variables in other ways, as we will see later.
+
+\starttyping
+\setMPpositiongraphic{G-1}{mypos:circle}
+\setMPpositiongraphic{G-1}{mypos:line}{to=G-2}
+\stoptyping
+
+In the second definition, we let the variable \type {to} point to another
+position. When needed, we can ask for the value of \type {to} by \type
+{\MPvar{to}}. For reasons of convenience, the current position is assigned
+automatically to \type {from} and \type {self}. This means that in the line we
+saw in the graphic:
+
+\starttyping
+path p ; p := positionbox(texstr("self")) ;
+\stoptyping
+
+\type {texstr("self")} will return the current position, which, fed to \type
+{positionbox} will return a box with the right dimensions. We already warned the
+reader: this is not an easy chapter.

+
+In this case the framed text will be placed in the background of the (current)
+page with the given offset to the topleft corner. Instead of a fixed position,
+you can inherit the current position using the \type {position} directive. Say
+that we have a layer called \type {YourLayer} which we put in the background of
+the text area.
+
+\startbuffer
+\definelayer[YourLayer]
+\setupbackgrounds[text][text][background=YourLayer]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We can now move some framed text to this layer using \type {\setlayer} with the
+directive \type {position} set to \type {yes}.
+
+\startbuffer
+here: \setlayer[YourLayer][position=yes]{\inframed{Here}}
+\stopbuffer
+
+\typebuffer
+
+You can influence the placement by explicitly providing an offset (\type
+{hoffset} and|/|or \type {voffset}), a position (\type {x} and|/|or \type {y}) or
+a location directive (\type {location}). Normally you will use the offsets for
+the layer as a whole and the positions for individual contributions. The next
+example demonstrates the use of a location directive.
+
+\startbuffer
+here: \setlayer[YourLayer][position=yes,location=c]{\inframed{Here}}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Many layers can be in use at the same time. In the next example we put something
+in the page layer. By default, we turn on position tracking, which visualizes the
+bounding box of the content and shows the reference point.

+
+Next we define an overlay that we can put behind for instance framed texts. We
+use \METAPOST\ to draw \type {Shape}.
+
+\startbuffer
+\defineoverlay[Shape] [BackLayer] [\uniqueMPgraphic{Shape}]
+

+We can now put this background shape behind the running text, for instance with:

+One of the reasons for developing the layer mechanism was that we needed to
+slightly change the position of figures in the final stage of typesetting. The
+previous pages demonstrate how one can position anything anywhere on the page,
+but in the case of figures the position may depend on where the text ends up on
+the page.
+
+Normally, when you manipulate a document this way, you are in the final stage of
+typesetting. You may qualify this as desk top publishing without actually using a
+desktop.

+The previous example also demonstrated the use of \METAPOST\ for rotating the
+picture. The \type {\MPfigure} macro encapsulates the code in a shortcut. You can
+achieve special effects by using the layers behind floating bodies and alike, but
+always keep in mind that the readability of the text should not be violated too
+much.
+
+\typebuffer[demo]
+
+In these examples we added a \type {\ruledhbox} around the pseudo graphics so
+that you can see what the size is of those graphics.
+
+% summary
+
+We have already seen a lot of parameters that can be used to control the content
+of a layer. There are a few more. General housekeeping takes place with:
+
+\starttabulate[|Tl|Tl|l|]
+\HL
+\NC state     \NC start   \NC enable the layer            \NC \NR
+\NC           \NC stop    \NC disable the layer           \NC \NR
+\NC position  \NC no      \NC use absolute positions      \NC \NR
+\NC           \NC yes     \NC use relative positions      \NC \NR
+\NC           \NC overlay \NC idem, but ignore the size   \NC \NR
+\NC direction \NC normal  \NC put new data on top         \NC \NR
+\NC           \NC reverse \NC put new data below old data \NC \NR
+\HL
+\stoptabulate
+
+Sometimes all data needs to be offset in a similar way. You can use both offset
+parameters for that.
+
+\starttabulate[|Tl|l|]
+\HL
+\NC hoffset \NC an additional horizontal displacement \NC \NR
+\NC voffset \NC an additional vertical   displacement \NC \NR
+\HL
+\stoptabulate
+
+You can position data anywhere in the layer. When positioning is turned on, the
+current position will get a placeholder. You can change the dimensions of that
+placeholder (when \type {position} is set to \type {overlay}), zero dimensions
+are used.
+
+\starttabulate[|Tl|l|]
+\HL
+\NC x        \NC the horizontal displacement \NC \NR
+\NC y        \NC the vertical   displacement \NC \NR
+\NC width    \NC the (non natural) width     \NC \NR
+\NC height   \NC the (non natural) height    \NC \NR
+\NC location \NC \tttf l r t b c lt lb rt rb \NC \NR
+\HL
+\stoptabulate
+
+The \type {location} directive determines what point of the data is used as
+reference point. You can keep track of this point and the placement when you
+enable test mode. This is how the rectangles in the previous examples were
+drawn.
+
+\starttabulate[|Tl|Tl|l|]
+\HL
+\NC option \NC test \NC show positioning information \NC \NR
+\HL
+\stoptabulate
+
+When you are enhancing the final version of a document, you can explicitly
+specify on what page the data will go. Use this option with care.
+
+\starttabulate[|Tl|l|]
+\HL
+\NC page \NC the page where the data will go \NC \NR
+\HL
+\stoptabulate
+
+Because layers can migrate to other pages, they may disappear due to the
+background not being recalculated. In case of doubt, you can force repetitive
+background calculation by:

+\index{text}
+
+If you like to embed \METAPOST\ snippets in \CONTEXT, you may want to combine
+text and graphics and let \METAPOST\ provide the position and the dimensions of
+the text to be typeset outside by \TEX. For most applications using the \METAFUN\
+\type {textext} macro works well enough, but when the typeset text needs to
+communicate with the typesetting engine, for instance because it contains
+hyperlinks or references, you can use the following method:
+
+\startitemize[packed]
+\item define a layer
+\item define a (reusable) graphic
+\item put your text into the layer
+\item combine the graphic with the text
+\stopitemize
+
+You must be aware of the fact that when the layer is flushed, its content is
+gone. You can take advantage of this by using the same graphic with multiple
+texts.

+\startintro
+
+In this chapter, we will demonstrate most of the drawing related primitives and
+macros as present in plain \METAPOST\ and \METAFUN\ extensions.
+
+If a path is shown and|/|or a transformation is applied, we show the original in
+red and the transformed path or point in yellow. The small dark gray crosshair is
+the origin and the black rectangle the bounding box. In some drawings, in light
+gray we show the points that make up the path.
+
+This list describes traditional \METAPOST\ and the stable part of \METAFUN. As
+\METAPOST\ evolves, new primitives are added but they are not always that
+relevant to us. If you browse the \METAFUN\ sources you will for sure notice more
+functionality than summarized here. Most of that is meant for usage in \CONTEXT\
+and not exposed to the user. Other macros are still somewhat experimental but
+might become more official at some point. The same is true for \METAFUN\
+commands: not all make sense for daily usage and some are just there as helper
+for additional modules.

+
+One characteristic of using \METAFUN\ in \CONTEXT\ is that it is basically one
+long run. The code snippets become figures that then get converted to \PDF\ and
+embedded. If text is involved, each figure is actually processed twice, once to
+identify what needs to be typeset, and once with the result(ing metrics).
+Normally that gets unnoticed. You can check for the state by consulting the
+boolean \type {mfun_trial_run}.
+
+A consequence of the one run cq.\ multiple runs is that you need to be careful with
+undefined or special variables. Consider the following:
+
+\starttyping
+vardef foo@#(text t) =
+    save s ; string s ; s := str @# ;
+    if length(s) > 0 :
+        textext(s)
+    else :
+        nullpicture
+    fi
+enddef ;
+\stoptyping
+
+The following works ok in the first run when bar is undefined:
+
+\starttyping
+draw foo.bar("a") ;
+\stoptyping
+
+But if afterwards we say:
+
+\starttyping
+vardef bar(expr x) =
+    123
+enddef ;
+\stoptyping
+
+and expand \type {foo.bar} again we will get an error message because this time
+\type {bar} expands. Suffixes are always expanded!
+
+The lesson is: when you get unexpected results or errors, check your variable
+definitions. You can use the \type {begingroup} and \type {endgroup} primitives
+to protect your variables but then you also need to explicitly use \type {save}
+to store their meanings and allocate new ones after that inside the group.

+\startchapter[title={Defining styles}]
+
+\index {layout}
+\index {styles}
+
+\startintro
+
+Since the integration of \METAPOST\ into \CONTEXT, a complete new range of layout
+fetaures became available. In this document we have introduced several ways to
+include graphics in your document definition. In this chapter we go one step
+further and make dynamic graphics part of a document style.
+
+\stopintro
+
+\startsection[title={Adaptive buttons}]
+
+So far we have seen a lot of graphic ingredients that you can use to make your
+documents more attractive. In this chapter we will define a simple document
+style. This style was written for the \PDFTEX\ presentations at the TUG 2000
+conference in Oxford (UK).
+
+This style exploits a few tricks, like graphics calculated using positional
+information. It also demonstrates how you can make menu buttons that dynamically
+adapt their shapes to the rest of the page layout.
+
+\startbuffer[screens]
+\startlinecorrection[blank]
+\setupcombinations[distance=.0125\textwidth]
+\startcombination[5*1]
+  {\typesetfile[mfun-77\ScrNum.tex][page=1,width=.19\textwidth]} {page 1}
+  {\typesetfile[mfun-77\ScrNum.tex][page=2,width=.19\textwidth]} {page 2}
+  {\typesetfile[mfun-77\ScrNum.tex][page=3,width=.19\textwidth]} {page 3}
+  {\typesetfile[mfun-77\ScrNum.tex][page=4,width=.19\textwidth]} {page 4}
+  {\typesetfile[mfun-77\ScrNum.tex][page=5,width=.19\textwidth]} {page 5}
+\stopcombination
+\stoplinecorrection
+\stopbuffer
+
+\def\ScrNum{1} \getbuffer[screens]
+
+Later we will see an instance with some more randomness in the graphics. While
+writing this style, the random alternative made me think of those organic
+buildings with non equal windows |<|we have a few of those in The Netherlands|>|,
+so I decided to label this style as \type {pre-organic}. If you use \CONTEXT, you
+can load this style with:
+
+\starttyping
+\usemodule[pre-organic]
+\stoptyping
+
+At the end of this file, there is a small test file, so when you process the file
+\type {s-pre-19.tex} \footnote {This style is the 19\high{th} presentation style.
+Those numbered styles are internally mapped onto more meaningful names like in
+this case \type {pre-organic}.} with the options \type {--mode=demo} and \type
+{--pdf}, you will get a demo document.
+
+We use one of the standard screen \quote {paper} sizes, and map it onto the same
+size, so that we get a nicely cropped page. Other screen sizes are \type {S4} and
+\type {S5}.
+
+\starttyping
+\setuppapersize[S6][S6]
+\stoptyping
+
+Like in this \METAFUN\ manual, we use the Palatino as main bodyfont. This font is
+quite readable on even low resolution screens, although I admit that this style
+is developed using an $1400\times1050$ pixel \kap {lcd} screen, so the author may
+be a little biased.
+
+\starttyping
+\setupbodyfont[ppl]
+\stoptyping
+
+The layout specification sets up a text area and a right edge area where the
+menus will go (see \in {chapter} [sec:page] for a more in depth discussion on the
+layout areas). Watch how we use a rather large edge distance. By setting the
+header and footer dimensions to zero, we automatically get rid of page body
+ornaments, like the page number.
+
+\starttyping
+\setuplayout
+  [topspace=48pt,
+   backspace=48pt,
+   cutspace=12pt,
+   width=400pt,
+   margin=0cm,
+   rightedge=88pt,
+   rightedgedistance=48pt,
+   header=0cm,
+   footer=0cm,
+   height=middle]
+\stoptyping
+
+We use a moderate, about a line height, inter||paragraph white space.
+
+\starttyping
+\setupwhitespace[big]
+\stoptyping
+
+Of course we use colors, since on computer displays they come for free.
+
+\starttyping
+\setupcolors[state=start]
+
+\definecolor [red]    [r=.75]
+\definecolor [yellow] [r=.75,g=.75]
+\definecolor [gray]   [s=.50]
+\definecolor [white]  [s=.85]
+\stoptyping
+
+Because it is an interactive document, we have to enable hyperlinks and alike.
+However, in this style, we disable the viewer's \quote {highlight a hyperlink
+when it's clicked on} feature. We will use a menu, so we enable menus. Later we
+will see the contrast color |<|hyperlinks gets that color when we are already on
+the location|>| in action.
+
+\starttyping
+\setupinteraction
+  [state=start,
+   click=off,
+   color=red,
+   contrastcolor=gray,
+   menu=on]
+\stoptyping
+
+The menu itself is set up as follows. Because we will calculate menu buttons
+based on their position on the page, we have to keep track of the positions.
+Therefore, we set the \type {position} variable to \type {yes}.
+
+\starttyping
+\setupinteractionmenu
+  [right]
+  [frame=off,
+   position=yes,
+   align=middle,
+   topoffset=-.75cm,
+   bottomoffset=-.75cm,
+   color=gray,
+   contrastcolor=gray,
+   style=bold,
+   before=,
+   after=]
+\stoptyping
+
+The menu content is rather sober: just a list of topics and a close button. Later
+we will define the command that generates topic entries. The alternative \type
+{right} lets the topic list inherit its characteristics from the menu.
+
+\starttyping
+\startinteractionmenu[right]
+  \placelist[Topic][alternative=right]
+  \vfill
+  \but [CloseDocument] close \\
+\stopinteractionmenu
+\stoptyping
+
+We have now arrived at the more interesting part of the style definition: the
+graphic that goes in the page background. Because this graphic will change, we
+define a useable \METAPOST\ graphic. Page backgrounds are recalculated each page,
+opposite to the other backgrounds that are calculated when a new background is
+defined, or when repetitive calculation is turned on.
+
+\starttyping
+\setupbackgrounds [page] [background=page]
+\defineoverlay    [page] [\useMPgraphic{page}]
+\setupMPvariables [page] [alternative=3]
+\stoptyping
+
+We will implement three alternative backgrounds. First we demonstrate the
+relatively simple super ellipsed one. The main complication is that we want the
+button shapes to follow the right edge of the curve that surrounds the text. We
+don't know in advance how many lines of text there will be in a button, and we
+also don't know at what height it will end up. Therefore, we need to calculate
+each button shape independently and for that purpose we need to know its position
+(see \in {chapter} [sec:positioning]). In \in {figure} [fig:style] you can see
+what lines we need in order to be calculate the button shapes.
+
+\startpostponing
+
+\startmode[screen]
+  \placefigure
+    [here][fig:style]
+    {The lines used to calculate the button shapes.}
+    {\externalfigure[mfun-774.pdf][page=1,height=.85\textheight]}

+    {\rotate{\externalfigure[mfun-774.pdf][page=1,height=\textwidth]}}
+\stopnotmode
+
+\page
+
+\stoppostponing
+
+We separate the calculation of the button shape from the rest by embedding it in
+its own usable graphic container. The \type {StartPage}||\type {StopPage} pair
+takes care of proper placement of the whole graphic.

+    draw p    withcolor \MPcolor{red} ;

+      if (pp>0) and (rr>0) :

+      fi ;
+    enddef ;
+
+    \MPmenubuttons{right}
+
+  StopPage ;
+\stopuseMPgraphic
+\stoptyping
+
+The \TEX\ macro \type {\MPmenubuttons} expands into a list of (in this case four)
+calls to the \METAPOST\ macro \type {right_menu_button}. This list is generated
+by \CONTEXT\ when it generates the menu. Because the page background is applied
+last, this list is available at that moment.
+
+\starttyping
+... (expr nn, rr, pp, xx, yy, ww, hh, dd) ...
+\stoptyping
+
+This rather long list of arguments represents the following variables: number,
+referred page, current page, x coordinate, y coordinate, width, height and depth.
+The last six variables originate from the positioning mechanism. Because the
+variables are only available after a second \TEX\ pass, we only draw a button
+shape when the test for the page numbers succeeds.
+
+\starttyping
+\startuseMPgraphic{rightsuperbutton}
+  vardef rightsuperbutton (expr pat, xpos, ypos, wid, hei) =
+
+    save p, ptop, pbot, t, b, edge, shift, width, height ;
+    path p, ptop, pbot ; pair t, b ;
+    numeric edge, shift, width, height ;
+
+    edge  := xpos + wid ; shift := ypos + hei ;
+
+    p := rightpath pat ;
+
+    ptop := ((-infinity,shift)--(edge,shift)) ;
+    pbot := ((-infinity,shift-hei)--(edge,shift-hei)) ;
+
+    t := p intersectionpoint ptop ;
+    b := p intersectionpoint pbot ;
+
+    p := subpath(0,xpart (p intersectiontimes ptop)) of p ;
+    p := subpath(xpart (p intersectiontimes pbot),length(p)) of p ;
+
+    (p --               t -- point 1 of ptop &
+          point 1 of ptop -- point 1 of pbot &
+          point 1 of pbot -- b
+       -- cycle)
+
+  enddef ;
+\stopuseMPgraphic
+\stoptyping
+
+The calculation of the button itself comes down to combining segments of the main
+shape and auxiliary lines. The \type {rightpath} macro returns the right half of
+the path provided. This half is shown as a non dashed line.
+
+Topics are identified with \type {\Topic}, which is an instance of chapter
+headings. The number is made invisible. Since it still is a numbered section
+header, \CONTEXT\ will write the header to the table of contents.
+
+\starttyping
+\definehead [Topic] [chapter]
+\setuphead  [Topic] [number=no]
+\stoptyping
+
+We will use a bold font in the table of contents. We also force a complete list.
+
+\starttyping
+\setuplist
+  [Topic]
+  [criterium=all,
+   style=bold,
+   before=,
+   after=]
+\stoptyping
+
+The \type {\TitlePage} macro looks horrible, because we want to keep the
+interface simple: a list of small sentences, separated by \type {\\}.
+
+\starttyping
+\def\TitlePage#1%
+  {\startstandardmakeup
+     \switchtobodyfont[big]
+     \def\\{\vfill\bfb\let\\=\par}
+     \bfd\setupinterlinespace\gray
+     \vskip.5cm#1\\\vskip.5cm  % \\ is really needed -)
+   \stopstandardmakeup}
+\stoptyping
+
+A presentation that uses this style, may look like the one below. You can choose
+among three alternatives.
+
+\starttyping
+\useenvironment[pre-organic] \setupoutput[pdftex]
+
+\setupMPvariables[page][alternative=1]
+
+\starttext
+
+\TitlePage
+  {A Few Nice Quotes\\

+\Topic {Donald E. Knuth}       \input knuth   \page
+\Topic {Edward R. Tufte}       \input tufte   \page
+\Topic {Hermann Zapf}          \input zapf    \page
+
+\stoptext
+\stoptyping
+
+We will not implement the two other alternative shapes: squeezed and randomized.
+
+\def\ScrNum{2} \getbuffer[screens]
+\def\ScrNum{3} \getbuffer[screens]
+
+We combine all alternatives into one page graphic. The alternative is chosen by
+setting the \type {alternative} variable, as we demonstrated in the example.
+
+\starttyping
+\startuseMPgraphic{page}
+
+  \includeMPgraphic{rightsuperbutton}
+
+  StartPage ;
+
+    numeric alternative, seed, superness, squeezeness, randomness ;
+    path p, q ; transform t ;
+\stoptyping
+
+This is one of those cases where a transform variable is useful. We need to store
+the random seed value because we want the larger path that is used in the
+calculations to have the same shape.
+
+\starttyping
+    alternative := \MPvar{alternative} ;
+    seed        := uniformdeviate 100 ;
+
+    if alternative > 10 :
+      superness   := .85  + ((\realfolio-1)/max(\lastpage,1)) * .25 ;
+      squeezeness := 12pt - ((\realfolio-1)/max(\lastpage,1)) * 10pt ;
+    else :
+      superness   := .90 ;
+      squeezeness := 12pt ;
+    fi ;
+
+    randomness := squeezeness ;
+
+    alternative := alternative mod 10 ;
+\stoptyping
+
+If you read closely, you will notice that when we add 10 to the alternative, we
+get a page dependant graphic. So, in fact we have five alternatives. We use
+\CONTEXT\ macros to fetch the (real) page number and the number of the last page.
+In further calculations we use the lower alternative numbers, which is why we
+apply a \type {mod}.
+
+The rest of the code is not so much different from the previous definition. The
+hard coded point sizes match the page dimensions (600pt by 450pt) quite well.
+
+\starttyping
+    t := identity if alternative=3: shifted (9pt,-9pt) fi ;
+
+    randomseed := seed ;
+
+    p := Field[Text][Text] enlarged if
+      alternative = 1 : 36pt superellipsed superness   elseif

+\startintro
+
+In the \METAFONT\ book as well as the \METAPOST\ manual, you can find the exact
+specification of the language. Below you find the full \METAPOST\ syntax, to
+which we add the basic \METAFUN\ extensions. If this page looks too cryptic, you
+can safely skip to the next chapter. We don't distinguish between primitives and
+functionality defined in the \METAPOST\ format, simply because the core is kept
+small and a macro package is supposed to extend that core.
+
+\stopintro
+
+% \startsection[title={Syntax diagrams}]
+
+The following syntax diagrams are derived from the diagrams in the \METAPOST\
+manual. The \mathematics {\rightarrow} represents \quote {means} and the
+\mathematics {\vert} symbol stands for \quote {or}.
+
+The diagrams describe the hard coded \METAPOST\ syntax as well as most of the
+macros and variables defined in the plain \METAPOST\ format that belongs to the
+core of the system. They also include most of the fundamental \METAFUN\ commands.
+We have omitted the \METAPOST\ and \METAFONT\ commands that make no sense any
+more or are irrelevant for common usage. Specific \METAFUN\ modules are not
+included here, only general tools, text helpers and extensions to the built||in
+capabilities like transparency. If you feel that something is missing that should
+be specified here, just let me know.

+\startchapter[reference=sec:typesetting,title={Typesetting in \METAPOST}]
+
+\startintro
+
+It is said that a picture tells more than a thousand words. So you might expect
+that text in graphics becomes superfluous. Out of experience we can tell you that
+this is not the case. In this chapter we explore the ways to add text to
+\METAPOST\ graphics, and let you choose whether or not to have it typeset by
+\TEX.
+
+\stopintro
+
+\startsection[title={The process}]
+
+\index{text}
+
+You can let \METAPOST\ process text that is typeset by \TEX. Such text is first
+embedded in the \METAPOST\ file in the following way:
+
+\starttyping
+btex Some text to be typeset by \TEX etex
+\stoptyping
+
+This returns a picture, but only after \METAPOST\ has made sure that \TEX\ has
+converted it into something useful. This process of conversion is slightly system
+dependent and even a bit obscure. Traditional \METAPOST\ calls a program that
+filters the \type {btex}|\unknown|\type {etex} commands, next it calls \TEX\ by
+passing the output routine, in order to make sure that each piece of text ends up
+on its own page, and afterwards it again calls a program that converts the \DVI\
+pages into \METAPOST\ pictures. In \LUATEX's \MPLIB\ a different route is
+followed.
+
+In \CONTEXT\ \MKII, when using \WEBC, you can generate the graphics at run||time.
+This takes more time than processing the graphics afterwards, but has the
+advantage that \TEX\ knows immediately what graphic it is dealing with. When
+enabled, \CONTEXT\ will call either \METAPOST, or, when the graphic contains
+\type {btex}||\type {etex} commands, call \TEXEXEC, which in turn makes sure that
+the right auxiliary programs are executed.
+
+In \CONTEXT\ \MKIV\ you won't notice this at all because everything is tightly
+integrated with \LUATEX's \MPLIB. This has an enormous speed gain: when this
+manual had about 425 pages, on my laptop with mobile 3840QM processor, one run of
+this document takes 18 seconds (14.5 with \LUAJITTEX) and that includes loadint a
+bunch of (outline) fonts and processing some 2200 \METAPOST\ images. While
+writing the first version of this manual runtime was upto 50 times slower for
+half the number of pages so compared to \MKII\ we have gained a lot.

+\startsection[title={Environments}]
+
+\index{environments}
+
+In case you want to pass code that is shared by all \type {btex}||\type {etex}
+pictures, \METAPOST\ provides:
+
+\starttyping
+verbatimtex \DefineSomeCommands etex ;
+\stoptyping
+
+However, in \CONTEXT\ one has a better mechanism available. In \CONTEXT\ \MKII\
+the advised method is passing environments. The best way to pass them is the
+following. As an example we switch to the 15 basic \POSTSCRIPT\ fonts.
+
+\startbuffer[pos]
+\startMPenvironment
+  \usetypescript[palatino][texnansi] % mkii has encodings
+  \setupbodyfont[palatino]
+\stopMPenvironment
+\stopbuffer
+
+\typebuffer[pos]
+
+This means that in code like the following, a Palatino font will be used.
+
+\starttyping
+\startMPcode
+draw btex Meta is a female lion! etex
+  xysized (\the\textwidth,\the\textheight) ;
+\stopMPcode
+\stoptyping
+
+However, in \CONTEXT\ \MKIV\ this method is no longer recomended as all
+processing happens in the same run anyway.
+
+% beware: extensive scaling can make acrobat crash and okular drop the !
+
+\startbuffer[lioncode]
+\startMPcode
+numeric w, h ; w := \the\textwidth ; h := w/2 ;
+
+picture p ; p := btex \colored[r=.375,g=.375]{Meta is a female lion!} etex
+    xysized (w,h) ;
+picture q ; q := btex \colored[r=.625]       {Meta is a female lion!} etex
+    xysized (w,h) ;
+
+path b ; b := boundingbox p ; draw p ;
+
+for i=(.28w,.90h),(.85w,.90h),(w,.05h) :
+  picture r ; r := q ;
+  path s ; s := (fullsquare xscaled .05w yscaled .4h) shifted i ;
+  clip r to s ; draw r ; % draw s ;
+endfor ;
+
+setbounds currentpicture to b ;
+\stopMPcode
+\stopbuffer
+
+\typebuffer[lioncode]
+
+\in {Figure} [lionclip] shows the previous sentence in a slightly different look.
+You may consider coloring the dots to be an exercise in clipping.
+
+\getbuffer[pos]
+
+\placefigure
+  [here][lionclip]
+  {An example of clipping.}
+  {\getbuffer[lioncode]}
+
+\resetMPenvironment
+
+An environment can be reset with \typ {\resetMPenvironment} or by passing \type
+{reset} to \typ {\startMPenvironment}.
+
+\starttyping
+\startMPenvironment[reset]
+  \usetypescript[postscript][texnansi] % mkii
+  \setupbodyfont[postscript]
+\stopMPenvironment
+\stoptyping
+
+So, to summarize: if you're using \CONTEXT\ \MKIV\ you might as well forgot what
+you just read.
+
+\stopsection
+
+\startsection[title={Labels}]
+
+\index{labels}
+
+In \METAPOST\ you can use the \type {label} macro to position text at certain
+points.
+
+\starttyping
+label("x", origin) ;
+\stoptyping
+
+The font and scale are determined by two variables, \type {defaultfont} and \type
+{defaultscale}, the former expecting the name of a font in the form of a string,
+the latter expecting a numeric to be used in the scaling of the font. Should you
+choose not to set these yourself, they default to \type {"Mono"} and \type
+{1.0}, respectively. However, you can change the defaults as follows:
+
+\starttyping
+defaultfont  := "texgyrepagella-regular*default" ;
+defaultscale := 1.2 ;
+\stoptyping
+
+These settings selects Pagella at about 12pt. You can also set these variables
+to \CONTEXT\ related values. For \CONTEXT\ graphics they are set to:
+
+\starttyping
+defaultfont  := "\truefontname{Regular}*default" ;
+defaultscale := \the\bodyfontsize/10 ;
+\stoptyping
+
+This means that they will adapt themselves to the current body font (in this
+document we get \truefontname{Regular}) and the current size of the bodyfont
+(here \the\bodyfontsize/10).
+
+\stopsection
+
+\startsection[title={\TeX\ text}]
+
+\index{text}
+
+In the next example we will use a special mechanism for building graphics step by
+step. The advantage of this method is that we can do intermediate calculations in
+\TEX. Our objective is to write a macro that draws text along a circular path.
+While doing so we want to achieve the following:
+
+\startitemize[packed]
+\item  the text should be properly kerned, i.e.\ the
+       spacing between characters should be optimal,
+\item  the position on the circle should vary, and
+\item  the radius of the circle should vary.
+\stopitemize
+
+This implementation is not the most straightforward one, but by doing it step by
+step, at least we see what is involved. Later, we will see a better method. If
+you run these examples yourself, you must make sure that the \TEX\ environment of
+your document matches the one used by \METAPOST.
+
+We let the bodyfont match the font used in this document, and define \type
+{RotFont} to be the regular typeface, the one you are reading right now, but
+bold.
+
+\startbuffer
+\definefont[RotFont][RegularBold*default]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Since \METAPOST\ is unaware of kerning, we have to use \TEX\ to keep track of the
+positions. We will split the text into tokens (often characters) and store the
+result in an array of pictures (\type {pic}). We will also store the accumulated
+width in an array (\type {len}). The number of characters is stored in~\type {n}.
+In a few paragraphs we will see why the other arrays are needed.
+
+While defining the graphic, we need \TEX\ to do some calculations. Therefore, we
+will use \type {\startMPdrawing} to stepwise construct the definition. The basic
+pattern we will follow is:
+
+\starttyping
+\resetMPdrawing
+\startMPdrawing
+  metapost code
+\stopMPdrawing
+tex code
+\startMPdrawing
+  metapost code
+\stopMPdrawing
+\MPdrawingdonetrue
+\getMPdrawing
+\stoptyping
+
+In the process, we will use a few variables. We will store the individual
+characters of the text in the variable \type {pic}, its width in \type {wid} and
+the length of the string so far in \type {len}. Later we will use the \type {pos}
+array to store the position where a character ends up. The variable \type {n}
+holds the number of tokens.
+
+\startbuffer[init]
+\resetMPdrawing
+\startMPdrawing
+  picture pic[] ;
+  numeric wid[], len[], pos[], n ;
+  wid[0] := len[0] := pos[0] := n := 0 ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[init]
+
+We also started fresh by resetting the drawing. From now on, each start command
+will add some more to this graphic. The next macro is responsible for collecting
+the data. Each element is passed on to \TEX, using the \type {btex} construct.
+So, \METAPOST\ itself will call \TEX !
+
+\startbuffer[toks]
+\def\whatever#1%
+  {\appendtoks#1\to\MPtoks
+   \setbox\MPbox=\hbox{\bfd\the\MPtoks}%
+   \startMPdrawing
+     n := n + 1 ; len[n] := \the\wd\MPbox ;
+   \stopMPdrawing
+   \startMPdrawing[-]
+     pic[n] := textext("\bfd\setstrut\strut#1") ;
+     pic[n] := pic[n] shifted - llcorner pic[n] ;
+   \stopMPdrawing}
+
+\handletokens MetaPost is Fun!\with\whatever
+\stopbuffer
+
+\typebuffer[toks]
+
+We use the low level \CONTEXT\ macro \type {\appendtoks} to extend the token list
+\type {\MPtoks}. The \type {\handletokens} macro passes each token (character) of
+\typ {MetaPost is Fun!} to the macro \type {\whatever}. The tokens are appended
+to the token register \type {\MPtoks} (already defined). Then we typeset the
+content of \type {\MPtoks} in \type {\MPbox} (also already defined). The width of
+the box is passed to \METAPOST\ and stored in \type {len}.
+
+By default the content of the drawing is expanded, which means that the macro is
+replaced by its current meaning, so the current width ends up in the \METAPOST\
+file. The next part of the drawing, starting with \type {btex}, puts the token in
+a picture. This time we don't expand the drawing, since we want to pass font
+information. Here, the \type {[-]} suppresses expansion of \typ {btex \bfd #1
+etex}. The process is iterated by \type {\handletokens} for each character of the
+text \typ {MetaPost is Fun!}.
+
+Before we typeset the text, now available in pieces in \type {pic}, in a circle,
+we will first demonstrate what they look like. You may like to take a look at the
+file \type {mpgraph.mp} to see what is passed to \METAPOST.
+
+\startbuffer[test]
+\startMPdrawing
+  pair len ; len := origin ;
+  for i=1 upto n :
+    draw pic[i] shifted len ;
+    draw boundingbox pic[i] shifted len
+      withpen pencircle scaled .25pt withcolor red ;
+    len := len+(xpart urcorner pic[i]-xpart llcorner pic[i],0) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[test]
+
+\startbuffer[show]
+\MPdrawingdonetrue\getMPdrawing
+\stopbuffer
+
+We can call up this drawing with \type {\getMPdrawing}, but first we inform the
+compiler that our \METAPOST\ drawing is completed.
+
+\typebuffer[show]
+
+This results in:
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,test,show]
+\stoplinecorrection
+
+Compare this text with the text as typeset by \TEX:
+
+\blank \start \bfd MetaPost is Fun!\par \stop \blank
+
+and you will see that the text produced by \METAPOST\ is not properly kerned.
+When putting characters after each other, \TEX\ uses the information available in
+the font, to optimize the spacing between characters, while \METAPOST\ looks at
+characters as separate entities. But, since we have stored the optimal spacing in
+\type {len}, we can let \METAPOST\ do a better job. Let's first calculate the
+correction needed.
+
+\startbuffer[kern]
+\startMPdrawing
+  for i=1 upto n :
+    wid[i] := abs(xpart urcorner pic[i] - xpart llcorner pic[i]) ;
+    pos[i] := len[i]-wid[i] ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[kern]
+
+This compares well to the text as typeset by \TEX:
+
+\blank \start \bfd MetaPost is Fun!\par \stop \blank
+
+We can now use the values in \type {pos} to position the pictures according to
+what \TEX\ considered to be the best (relative) position.
+
+\startbuffer[test]
+\startMPdrawing
+  for i=1 upto n :
+    draw pic[i] shifted (pos[i],0) ;
+    draw boundingbox pic[i] shifted (pos[i],0)
+      withpen pencircle scaled .25pt withcolor red ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[test]
+
+That this correction is adequate, is demonstrated in the next graphic. If you
+look closely, you will see that for instance the \quote {o} is moved to the left,
+under the capital \quote {P}.
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,test,show]
+\stoplinecorrection
+
+When we want to position the pictures along a circle, we need to apply some
+rotations, especially because we want to go clockwise. Since we don't want to use
+\quote {complicated} math or more advanced \METAPOST\ code yet, we will do it in
+steps.
+
+\startbuffer[swap]
+\startMPdrawing
+  for i=1 upto n:
+    pic[i] := pic[i] rotatedaround(origin,-270) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[swap]
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,swap,test,show]
+\stoplinecorrection
+
+\startbuffer[cent]
+\startMPdrawing
+  for i=1 upto n :
+    pic[i] := pic[i]
+      shifted (0,ypart -.5[ulcorner pic[i],llcorner pic[i]]) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+We will now center the pictures around the baseline. Centering comes down to
+shifting over half the height of the picture. This can be expressed by:
+
+\starttyping
+ypart -.5[ulcorner pic[i],llcorner pic[i]]
+\stoptyping
+
+but different ways of calculating the distance are possible
+too.
+
+\typebuffer[cent]
+
+So, now we have:
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,swap,cent,test,show]
+\stoplinecorrection
+
+When we typeset on a (half) circle, we should map the actual length onto a
+partial circle. We denote the radius with an~\type {r} and shift the pictures to
+the left.
+
+\startbuffer[shif]
+\startMPdrawing
+  numeric r ; r := len[n]/pi ;
+  for i=1 upto n :
+    pic[i] := pic[i] shifted (-r,0) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[shif]
+
+You can now use the following code to test the current state of the pictures. Of
+course this code should not end up in the final definitions.
+
+\startbuffer[test]
+\startMPdrawing
+  draw origin
+    withpen pencircle scaled 5pt withcolor red ;
+  for i=1 upto n :
+    draw pic[i] ;
+    draw boundingbox pic[i]
+      withpen pencircle scaled .25pt withcolor red ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[test]
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,swap,cent,shif,test,show]
+\stoplinecorrection
+
+Later we will write a compact, efficient macro to take care of rotation. However,
+for the moment, so as not to overwhelm you with complicated code, we will rotate
+each individual picture with the following code fragment.
+
+\startbuffer[rots]
+\startMPdrawing
+  numeric delta, extra, radius, rot[] ;
+
+  delta  := extra := radius := 0 ;
+
+  for i=1 upto n :
+    rot[i] := extra+delta-((pos[i]+.5wid[i])/len[n])*(180+2delta) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[rots]
+
+Here we introduce a few variables that we can use later to tune the result a bit.
+With \type {delta}, the space between the characters can be increased, while
+\type {extra} rotates the whole string around the origin. The \type {radius}
+variable can be used to increase the distance to the origin. Without these
+variables, the assignment would have been:
+
+\starttyping
+rot[i] := ((pos[i]+.5wid[i])/len[n])*180 ;
+\stoptyping
+
+Placing the pictures is now rather easy:
+
+\startbuffer[done]
+\startMPdrawing
+  for i=1 upto n :
+    draw pic[i] shifted (-radius,0) rotatedaround(origin,rot[i]) ;
+  endfor ;
+\stopMPdrawing
+\stopbuffer
+
+\typebuffer[done]
+
+The pictures are now positioned on half a circle, properly kerned.
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,swap,cent,shif,rots,done,show]
+\stoplinecorrection
+
+A bit more insight is given in the next picture:
+
+\startbuffer[test]
+\startMPdrawing
+  def moved(expr i) =
+    shifted (-radius,0) rotatedaround(origin,rot[i])
+  enddef ;
+  pickup pencircle scaled .5pt ;
+  for i=1 upto n :
+    draw pic[i] moved(i) ;
+    draw boundingbox pic[i] moved(i) withcolor red ;
+    draw origin -- center pic[i] moved(i) withcolor green ;
+  endfor ;
+  draw tcircle scaled 2r withcolor blue ;
+\stopMPdrawing
+\stopbuffer
+
+\startlinecorrection[blank]
+\getbuffer[init,toks,kern,swap,cent,shif,rots,test,show]
+\stoplinecorrection
+
+This was defined as follows. The path variable \type {tcycle} is predefined to
+the top half of a fullcircle.
+
+\typebuffer[test]
+
+We will now package all of this into a nice, efficient macro, using, of course,
+the predefined scratch registers \type {\MPtoks} and \type {\MPbox}. First we
+define the token processor. Note again the expansion inhibition switch \type
+{[-]}.

+The previous macro is not really an example of generalization, but we used it for

+buffers, you can even combine steps and replace them at will. This is how we made
+the previous step by step examples: We put each sub||graphic in a buffer and then
+called the ones we wanted.
+
+We now present a more general approach to typesetting along a given path. This
+method is not only more robust and general, it is also a more compact definition,
+especially if we omit the tracing and testing code. We use a familiar auxiliary
+definition. The \type {\setstrut} and \type {\strut} commands ensure that the
+lines have the proper depth and height.

+
+Sometimes, others may say oftentimes, we are in need for some fancy typesetting.
+If we want to typeset a paragraph of text in a non standard shape, like a circle,
+we have to fall back on \type {\parshape}. Unfortunately, \TEX\ is not that
+strong in providing the specifications of more complicated shapes, unless you are
+willing to do some complicated arithmetic \TEX. Given that \METAPOST\ knows how
+to deal with shapes, the question is: \quotation {Can \METAPOST\ be of help?}
+
+In the process of finding out how to deal with this, we first define a simple
+path. Because we are going to replace pieces of code, we will compose the graphic
+from components. First, we create the path.
+
+\startbuffer
+\startuseMPgraphic{text path}
+  path p ; p := ((0,1)..(-1,0)..(1,0)--cycle) scaled 65pt ;

+us to identify bordercases.

+\startuseMPgraphic{text draw}
+  drawarrow p withpen pencircle scaled 1pt withcolor red ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Now we use \CONTEXT's \type {\includeMPgraphic} command to build our graphic from
+the previously defined components.

+
+\typebuffer \getbuffer
+
+When called with \type {\useMPgraphic{text}}, we get:
+
+\startlinecorrection[blank]
+\useMPgraphic{text}
+\stoplinecorrection
+
+For the moment we start the path at $(x=0,y>0)$, but later using more complicated
+macros, we will see that we can use arbitrary paths.
+
+We are going to split the path in two, and will use the points that make up the
+bounding box as calcutated by \METAPOST. The next graphic shows one of these
+points, the lower left corner, available as point \typ {llcorner p}.
+
+\startbuffer
+\startuseMPgraphic{text draw}
+  draw             p withpen pencircle scaled 3pt withcolor red ;

+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startlinecorrection[blank]
+\useMPgraphic{text}
+\stoplinecorrection
+
+The five points that \METAPOST\ can report for each path or picture are:
+
+\starttabulate[|Tl|l|]
+\NC llcorner \NC lower left  corner            \NC \NR
+\NC lrcorner \NC lower right corner            \NC \NR

+\NC ulcorner \NC upper left  corner            \NC \NR
+\NC center   \NC intersection of the diagonals \NC \NR
+\stoptabulate
+
+If we want to typeset text inside this circle, we need to know where a line
+starts and ends. Given that lines are horizontal and straight, we therefore need
+to calculate the intersection points of the lines and the path. As a first step,
+we calculate the top and bottom of the path and after that we split off the left
+and right path.
+
+\startbuffer
+\startuseMPgraphic{text split}
+  pair t, b ; path l, r ;
+
+  t := (ulcorner p -- urcorner p) intersectionpoint p ;
+  b := (llcorner p -- lrcorner p) intersectionpoint p ;
+
+  l := p cutbefore t ; l := l cutafter b ;
+  r := p cutbefore b ; r := r cutafter t ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \type {intersectionpoint} macro returns the point where two paths cross. If
+the paths don't cross, an error is reported, when the paths cross more times,
+just one point is returned. The \type {cutafter} and \type {cutbefore} commands
+do as their names say and return a path.
+
+In the \type {text split} code fragment, \type {t} and \type {b} are the top
+points of the main path, while \type {l} and \type {r} become the left and right
+half of path \type {p}.
+
+We now draw the original path using a thick pen and both halves with a thinner
+pen on top of the original. The arrows show the direction.

+
+We use \type {\includeMPgraphic} to assemble the components:

+
+This graphic is typeset with \type {\useMPgraphic{text}}:
+
+\startlinecorrection[blank]
+\useMPgraphic{text}
+\stoplinecorrection
+
+Before we are going to use them, we define some variables that specify the text.
+We use a baseline distance of 8~points. The part of the line above the baseline
+is 7.2~points, while the (maximum) depth is 2.8~points. These ratios are the ones
+we use in \CONTEXT. Because we don't want the text to touch the circle so we
+define an offset too.
+
+\startbuffer
+\startuseMPgraphic{text vars}
+  baselineskip := 8pt ;
+  strutheight  := (7.2/10) * baselineskip ;
+  strutdepth   := (2.8/10) * baselineskip ;
+  offset       := baselineskip/2 ;
+  topskip      := strutheight ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We more or less achieve the offset by scaling the path. In doing so, we use the
+width and height, which we call \type {hsize} and \type {vsize}, thereby
+conforming to the \TEX\ naming scheme.
+
+First we calculate both dimensions from the bounding box of the path. Next we
+down scale the path to compensate for the offset. When done, we recalculate the
+dimensions.
+
+\startbuffer
+\startuseMPgraphic{text move}
+  pair t, b ; path q, l, r ;
+
+  hsize := xpart lrcorner p - xpart llcorner p ;
+  vsize := ypart urcorner p - ypart lrcorner p ;
+
+  q := p xscaled ((hsize-2offset)/hsize)
+         yscaled ((vsize-2offset)/vsize) ;

+
+The offset is not optimal. Note the funny gap at the top. We could try to fix
+this, but there is a better way to optimize both paths.
+
+We lower the top edge of \type {q}'s bounding box by \type {topskip}, then cut
+any part of the left and right pieces of \type {q} that lie above it. Similarly,
+we raise the bottom edge and cut off the pieces that fall below this line.

+that are not centered around the origin and don't start at the top point. We
+achieve this by moving the path to the center:
+
+\starttyping
+cp := center p ; q := p shifted - cp ;
+\stoptyping
+
+The arbitrary starting point is taken care of by a slightly more complicated path
+cutter. First we make sure that the path runs counterclockwise.
+
+\starttyping
+if xpart directionpoint t of q < 0 : q := reverse q fi ;
+\stoptyping
+
+Knowing this, we can split the path in two, using a slightly different splitter:
+
+\starttyping
+l := q cutbefore t ;
+l := l if xpart point 0 of q < 0 : & q fi cutafter b ;
+r := q cutbefore b ;
+r := r if xpart point 0 of q > 0 : & q fi cutafter t ;
+\stoptyping
+
+As always, when implementing a feature like this, some effort goes into a proper
+user interface. In doing so, we need some \TEX\ trickery that goes beyond this
+text, like collecting text and splitting of the part needed. Also, we want to be
+able to handle multiple shapes at once, like the next example demonstrates.
+
+\stopsection
+
+\startsection[title={Libraries}]
+
+\index{graphics+libraries}
+
+The macro discussed in the previous section is included in one of the \METAPOST\
+libraries, so we first have to say:
+
+\startbuffer
+\useMPlibrary[txt]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We define four shapes. They are not really beautiful, but they demonstrate what
+happens in border cases. For instance, too small first lines are ignored. First
+we define a circle. Watch how the dimensions are set in the graphic. The
+arguments passed to \type {build_parshape} are: path, an offset, an additional
+horizontal and vertical displacement, the baseline distance, the height and depth
+of the line, and the height of the first line (topskip in \TEX\ terminology). The
+height and depth of a line are often called strut height and depth, with a strut
+being an invisible character with maximum dimensions.
+
+\startbuffer
+\startuseMPgraphic{test 1}
+  path p ; p := fullcircle scaled 6cm ;
+
+  build_parshape(p,6pt,0,0,\baselinedistance,
+    \strutheight,\strutdepth,\strutheight) ;
+
+  draw p withpen pencircle scaled 1pt ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The second shape is a diamond. This is a rather useless shape, unless the text
+suits the small lines at the top and bottom.
+
+\startbuffer
+\startuseMPgraphic{test 2}
+  path p ; p := fullsquare rotated 45 scaled 5cm ;
+
+  build_parshape(p,6pt,0,0,\baselinedistance,
+    \strutheight,\strutdepth,\strutheight) ;
+
+  draw p withpen pencircle scaled 1pt ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The third and fourth shape demonstrate that providing a suitable offset is not
+always trivial.
+
+\startbuffer
+\startuseMPgraphic{test 3}
+  numeric w, h ; w := h := 6cm ;
+  path p ; p := (.5w,h) -- (0,h) -- (0,0) -- (w,0) &
+    (w,0) .. (.75w,.5h) .. (w,h) & (w,h) -- cycle ;
+
+  build_parshape(p,6pt,0,0,\baselinedistance,
+    \strutheight,\strutdepth,\strutheight) ;
+
+  draw p withpen pencircle scaled 1pt ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Contrary to the first three shapes, here we use a different path for the
+calculations and the drawing. Watch carefully! If, instead of an offset, we pass
+a path, \METAPOST\ is able to calculate the right dimensions and offsets. This is
+needed, since we need these later on.
+
+\startbuffer
+\startuseMPgraphic{test 4}
+  numeric w, h, o ;
+
+  def shape = (o,o) -- (w-o,o) & (w-o,o) .. (.75w-o,.5h) ..
+    (w-2o,h-o) & (w-2o,h-o) -- (o,h-o) -- cycle
+  enddef ;
+
+  w := h := 6cm ; o := 6pt ; path p ; p := shape ;
+  w := h := 6cm ; o := 0pt ; path q ; q := shape ;
+
+  build_parshape(p,q,6pt,6pt,\baselinedistance,
+    \strutheight,\strutdepth,\strutheight) ;
+
+  draw q withpen pencircle scaled 1pt ;
+\stopuseMPgraphic
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Since we also want these graphics as backgrounds, we define them as overlays. If
+you don't want to show the graphic, you may omit this step.
+
+\startbuffer
+\defineoverlay[test 1][\useMPgraphic{test 1}]
+\defineoverlay[test 2][\useMPgraphic{test 2}]
+\defineoverlay[test 3][\useMPgraphic{test 3}]
+\defineoverlay[test 4][\useMPgraphic{test 4}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+As text, we use a quote from Douglas R.~Hofstadter's book \quotation {Metamagical
+Themas, Questing for the Essence of Mind and Pattern}. Watch how we pass a list
+of shapes.
+
+\startbuffer[text]
+\startshapetext[test 1,test 2,test 3,test 4]
+  \forgetall % as it says
+  \setupalign[verytolerant,stretch,normal]%
+  \input douglas % Douglas R. Hofstadter
+\stopshapetext
+\stopbuffer
+
+\typebuffer[text]
+
+Finally we combine text and shapes. Since we also want a background, we use \type
+{\framed}. The macros \type {\parwidth} and \type {\parheight} are automatically
+set to the current shape dimensions. The normal result is shown in \in {figure}
+[fig:shapes].

+% {\em This mechanism is still somewhat experimental and will be optimized and

+
+We can combine all those tricks, although the input is somewhat fuzzy. First we

+
+% \startsection[title={Visualizing \TEX}]
+%
+% The next example is a bit out of place in this manual, but nevertheless
+% demonstrates how one can use \METAPOST\ to get insight in what \TEX\ is doing
+% inside.
+%
+% The author of \PDFTEX, \THANH, has extended the paragraph builder with a
+% provision for protruding characters and glyphs substitution, also known as {\it
+% hz} (which stands for Hermann Zapf). The {\it hz} optimization involves an
+% additional pass over the lines and|/|or paragraph, in order to determine how
+% inconsistency in gaps can be reduced by substituting an \quote {\scale [sx=1.01]
+% {a}} by an \quote {\scale [sx=5] {a}} or \quote {\scale [sx=.5] {a}}. In \in
+% {figure} [fig:hz] you can find the visualization in action. By means of colors we
+% indicate in what way glyphs are substituted by slightly larger or smaller values.
+% More details on how the {\it hz} optimization works can be found in \THANH's
+% thesis.
+%
+% \placefigure
+%   [page][fig:hz]
+%   {When we feed \TEX\ code into \METAPOST\ and back, we
+%    can visualize {\it hz}||optimization in a colorful way.}
+%   {\doifmodeelse{screen}
+%      {\externalfigure[mfun-hzs.pdf][height=.8\textheight]}
+%      {\externalfigure[mfun-hzp.pdf][height=.8\textheight]}}
+%
+% In order to avoid a complicated discussion about how to set up \PDFTEX\ to use
+% {\it hz} |<|this can best be left over to the macro package that you use|>| we
+% will illustrate the method behind this kind of visualizations in a more simple
+% case.
+%
+% When you include a \METAPOST\ graphic in \PDFTEX, the output produced by
+% \METAPOST\ is interpreted by a bunch of macros and converted into raw \PDF\ code.
+% In the process special extensions, like shading, transparency, graphic inclusion,
+% are taken care of. When the converter encounters a font inclusion directive,
+% i.e.\ the \POSTSCRIPT\ \type {fshow} operator, it uses the \TEX\ font handler to
+% take care of the font. A benefit of this approach is that \TEX\ and \METAPOST\
+% share the same font resources and therefore the inclusion is done in the way
+% expected.
+%
+% The low level macro that takes care of the font inclusion provides a couple of so
+% called hooks, that permit us to do additional manipulations with the character
+% sequences that are encountered.
+%
+% \startbuffer[demo]
+% draw
+%   btex \definedfont[cmr10]%
+%     Combine the power of \TeX\ and \MetaPost !
+%   etex scaled 2 ;
+% \stopbuffer
+%
+% \typebuffer[demo]
+%
+% When processed, this gives the graphic:
+%
+% \startlinecorrection[blank]
+% \processMPbuffer[demo]
+% \stoplinecorrection
+%
+% The result is not spectacular, and there is no indication that \METAPOST\ has
+% been in action. The following line of code sets the hook \type {\MPfshowcommand}
+% |<|this commands takes one argument|>| to produce a ruled horizontal box.
+%
+% \startbuffer
+% \let\MPfshowcommand\ruledhbox
+% \stopbuffer
+%
+% \typebuffer
+%
+% \startlinecorrection[blank]
+% \getbuffer \processMPbuffer[demo]
+% \stoplinecorrection
+%
+% If you watch closely, you will see that the ruled boxes contain one or more
+% characters (or more precise glyphs). This is a result from \TEX\ explicitely
+% kerning characters.
+%
+% A second hook is provided in the macro that takes care of the font switch. This
+% command is defined as follows:
+%
+% \starttyping
+% \def\setMPfshowfont#1#2%
+%   {\font\temp=#1\space at #2\relax\temp}
+% \stoptyping
+%
+% The first argument is the raw font name, and the second argument specifies the
+% desired size. If we want to see what fonts are involved, we can redefine the
+% hooks as follows.
+%
+% \starttyping
+% \def\setMPfshowfont#1#2%
+%   {\message{[using #1 at #2 in mp graphic]}%
+%    \font\temp=#1\space at #2\relax\temp}
+% \stoptyping
+%
+% It happens that two fonts are used: \type {cmr10} and \type {logo10}. Once we
+% know this, we can apply some magic: we set the color to the fontname and define a
+% couple of colors that match the name.
+%
+% \startbuffer
+% \definecolor [cmr10]  [darkred]
+% \definecolor [logo10] [darkyellow]
+%
+% \def\setMPfshowfont#1#2%
+%   {\color[#1]\font\temp=#1\space at #2\relax\temp}
+% \stopbuffer
+%
+% \typebuffer
+%
+% In the case of the \type {\it hz} examples we had to define a couple of more
+% colors, but the principle remains.
+%
+% \startlinecorrection[blank]
+% \getbuffer \processMPbuffer[demo]
+% \stoplinecorrection
+%
+% We don't expect the user to use tricks like this on a daily basis, but it
+% demonstrates that with a bit of knowlegde of the internals of \CONTEXT, you can
+% produce nice examples of typographic programming.

+
+\startintro
+
+In this chapter, we will introduce the most important \METAPOST\ concepts as well
+as demonstrate some drawing primitives and operators. This chapter does not
+replace the \METAFONT\ book or \METAPOST\ manual, both of which provide a lot of
+explanations, examples, and (dirty) tricks.
+
+As its title says, the \METAFONT\ book by Donald.\ E.\ Knuth is about fonts.
+Nevertheless, buying a copy is worth the money, because as a \METAPOST\ user you
+can benefit from the excellent chapters about curves, algebraic expressions, and
+(linear) equations. The following sections are incomplete in many aspects. More
+details on how to define your own macros can be found in both the \METAFONT\ book
+and \METAPOST\ manual, but you will probably only appreciate the nasty details if
+you have written a few simple figures yourself. This chapter will give you a
+start.
+
+A whole section is dedicated to the basic extensions to \METAPOST\ as provided by
+\METAFUN. Most of them are meant to make defining graphics like those shown in
+this document more convenient.
+
+Many of the concepts introduced here will be discussed in more detail in later
+chapters. So, you may consider this chapter to be an appetizer for the following
+chapters. If you want to get started quickly, you can safely skip this chapter
+now.
+
+\stopintro
+
+\startsection[title={Paths}]
+
+\index{paths}
+
+Paths are the building blocks of \METAPOST\ graphics. In its simplest form, a
+path is a single point.
+
+\startuseMPgraphic{axis}
+  tickstep := 1cm ; ticklength := 2mm ;
+  drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ;
+  tickstep := tickstep/2 ; ticklength := ticklength/2 ;
+  drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ;
+\stopuseMPgraphic
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  drawpoint "1cm,1.5cm" ;
+\stopMPcode
+\stoplinecorrection
+
+Such a point is identified by two numbers, which represent the horizontal and
+vertical position, often referred to as $x$ and $y$, or $(x,y)$. Because there
+are two numbers involved, in \METAPOST\ this point is called a pair. Its related
+datatype is therefore \type {pair}. The following statements assigns the point we
+showed previously to a pair variable.
+
+\starttyping
+pair somepoint ; somepoint := (1cm,1.5cm) ;
+\stoptyping
+
+A pair can be used to identify a point in the two dimensional coordinate space,
+but it can also be used to denote a vector (being a direction or displacement).
+For instance, \type {(0,1)} means \quote {go up}. Looking through math glasses,
+you may consider them vectors, and if you know how to deal with them, \METAPOST\
+may be your friend, since it knows how to manipulate them.
+
+You can connect points and the result is called a path. A path is a straight or
+bent line, and is not necessarily a smooth curve. An example of a simple
+rectangular path is: \footnote {In the next examples we use the debugging
+features discussed in \in {chapter} [sec:debugging] to visualize the points,
+paths and bounding boxes.}
+
+\startuseMPgraphic{path}
+  path p ;
+  p := unitsquare xyscaled (2cm,1cm) shifted (.5cm,.5cm) ;
+\stopuseMPgraphic
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  drawpath p ;
+\stopMPcode
+\stoplinecorrection
+
+This path is constructed out of four points:
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  swappointlabels := true ; drawpath p ; drawpoints p ;
+\stopMPcode
+\stoplinecorrection
+
+Such a path has both a beginning and end and runs in a certain direction:
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  autoarrows := true ;
+  swappointlabels := true ; drawarrowpath p ; drawpoints p ;
+\stopMPcode
+\stoplinecorrection
+
+A path can be open or closed. The previous path is an example of a closed path.
+An open path looks like this:
+
+\startuseMPgraphic{path}
+  path p ; p := (1cm,1cm)..(1.5cm,1.5cm)..(2cm,0cm) ;
+\stopuseMPgraphic
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  swappointlabels := true ; drawpath p ; drawpoints p ;
+\stopMPcode
+\stoplinecorrection
+
+When we close this path |<|and in a moment we will see how to do this|>| the path
+looks like:
+
+\startbuffer
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  p := p .. cycle ;
+  swappointlabels := true ; drawpath p ; drawpoints p ;
+\stopMPcode
+\stoplinecorrection
+\stopbuffer
+
+\getbuffer
+
+The open path is defined as:
+
+\starttyping
+(1cm,1cm)..(1.5cm,1.5cm)..(2cm,0cm)
+\stoptyping
+
+The \quote {double period} connector \type {..} tells \METAPOST\ that we want to
+connect the lines by a smooth curve. If you want to connect points with straight
+line segments, you should use \type {--}.
+
+Closing the path is done by connecting the first and last point, using the \type
+{cycle} command.
+
+\starttyping
+(1cm,1cm)..(1.5cm,1.5cm)..(2cm,0cm)..cycle
+\stoptyping
+
+Feel free to use \type {..} or \type {--} at any point in your path.
+
+\starttyping
+(1cm,1cm)--(1.5cm,1.5cm)..(2cm,0cm)..cycle
+\stoptyping
+
+\startuseMPgraphic{path}
+path p ; p := (1cm,1cm)--(1.5cm,1.5cm)..(2cm,0cm)..cycle ;
+\stopuseMPgraphic
+
+This path, when drawn, looks like this:
+
+\getbuffer
+
+As you can see in some of the previous examples, \METAPOST\ is capable of drawing
+a smooth curve through the three points that make up the path. We will now
+examine how this is done.
+
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  p := p .. cycle ; swappointlabels := true ;
+  drawpath p ; drawcontrollines p ; drawpoints p ; drawcontrolpoints p ;
+\stopMPcode
+\stoplinecorrection
+
+The six small points are the so called control points. These points pull their
+parent point in a certain direction. The further away such a point is, the
+stronger the pull.
+
+Each point has at most two control points. As you can see in the following
+graphic, the endpoints of a non closed curve have only one control point.
+
+\startuseMPgraphic{path}
+path p ; p := (1.5cm,1.5cm)..(2cm,0cm)..(1cm,1cm) ;
+\stopuseMPgraphic
+
+\startbuffer[path]
+\startlinecorrection[blank]
+\startMPcode
+  \includeMPgraphic{axis}
+  \includeMPgraphic{path}
+  swappointlabels := true ;
+  drawpath p ; drawcontrollines p ; drawpoints p ; drawcontrolpoints p ;
+\stopMPcode
+\stoplinecorrection
+\stopbuffer
+
+\getbuffer[path]
+
+This time we used the path:
+
+\starttyping
+(1.5cm,1.5cm)..(2cm,0cm)..(1cm,1cm)
+\stoptyping
+
+When you connect points by a smooth curve, \METAPOST\ will calculate the control
+points itself, unless you specify one or more of them.
+
+\startuseMPgraphic{path}
+  path p ; p := (1cm,1cm)..(1.5cm,1.5cm)..controls (3cm,2cm)..(2cm,0cm) ;
+\stopuseMPgraphic
+
+\getbuffer[path]
+
+This path is specified as:

+
+In this path, the second and third point share a control point. Watch how the
+curve is pulled in that direction. It is possible to pull a bit less by choosing
+a different control point:
+
+\starttyping
+(1cm,1cm)..(1.5cm,1.5cm)..controls (2.75cm,1.25cm)..(2cm,0cm)

+
+In this graphic, the path stored in \type {p} is drawn twice, once in its
+displaced form. The displacement is defined as:
+
+\starttyping
+p shifted (4cm,2cm)
+\stoptyping
+
+In a similar fashion you can rotate a path. You can even combine shifts and
+rotations. First we rotate the path 15 degrees counter||clockwise around the
+origin.
+
+\starttyping
+p rotated 15
+\stoptyping
+
+\startuseMPgraphic{path}
+  path p ; p := (1cm,1cm)..(1.5cm,2cm)..(2cm,0cm)..cycle ;
+  path q ; q := p rotated 15 ;
+\stopuseMPgraphic
+
+\getbuffer[path]
+
+This rotation becomes more visible when we also shift the path to the right by
+saying:
+
+\starttyping
+rotated 15 shifted (4cm,0cm)
+\stoptyping
+
+Now we get:
+
+\startuseMPgraphic{path}
+  path p ; p := (1cm,1cm)..(1.5cm,2cm)..(2cm,0cm)..cycle ;
+  path q ; q := p rotated 15 shifted (4cm,0cm) ;
+\stopuseMPgraphic
+
+\getbuffer[path]
+
+Note that \type {rotated 15} is equivalent to \typ {p rotatedaround (origin,
+15)}.
+
+It may make more sense to rotate the shape around its center. This can easily be
+achieved with the \type {rotatedaround} command. Again, we move the path to the
+right afterwards.

+\stopuseMPgraphic
+
+\getbuffer[path]
+
+Yet another transformation is slanting. Just like characters can be upright or
+slanted, a graphic can be:
+
+\starttyping
+p slanted 1.5 shifted (4cm,0cm)
+\stoptyping
+
+\startuseMPgraphic{path}
+  path p ; p := (1cm,1cm)..(1.5cm,2cm)..(2cm,0cm)..cycle ;
+  path q ; q := p slanted 1.5 shifted (4cm,0cm) ;
+\stopuseMPgraphic
+
+\getbuffer[path]
+
+The slant operation's main application is in tilting fonts. The $x$||coodinates
+are increased by a percentage of their $y$||coordinate, so here every $x$ becomes
+$x+1.5y$. The $y$||coordinate is left untouched. The following table summarizes
+the most important primitive transformations that \METAPOST\ supports.

+
+A \type {zscaled} specification takes a vector as argument:

+\starttyping
+p zscaled (2,.5)
+\stoptyping
+
+The result looks like a combination of scaling and rotation, and conforms to the
+formula in the previous table.
+
+Transformations can be defined in terms of a transform matrix. Such a matrix is
+stored in a transform variable. For example:
+
+\starttyping
+transform t ; t := identity scaled 2cm shifted (4cm,1cm) ;
+\stoptyping
+
+We use the associated keyword \type {transformed} to apply this matrix to a path
+or picture.
+
+\starttyping
+p transformed t
+\stoptyping
+
+In this example we've taken the \type {identity} matrix as starting point but you
+can use any predefined transformation. The identity matrix is defined in such a
+way that it scales by a factor of one in both directions and shifts over the
+zero||vector.
+
+Transform variables can save quite some typing and may help you to force
+consistency when many similar transformations are to be done. Instead of changing
+the scaling, shifting and other transformations you can then stick to just
+changing the one transform variable.

+
+We've used the commands \type {..} and \type {--} as path connecting directives.
+In the next series of examples, we will demonstrate a few more. However, before
+doing that, we define a few points, using the predefined \type {z} variables.
+
+\startuseMPgraphic{points}
+  z0 = (0.5cm,1.5cm) ; z1 = (2.5cm,2.5cm) ;
+  z2 = (6.5cm,0.5cm) ; z3 = (3.0cm,1.5cm) ;

+z0 = (0.5cm,1.5cm) ; z1 = (2.5cm,2.5cm) ;
+z2 = (6.5cm,0.5cm) ; z3 = (3.0cm,1.5cm) ;
+\stoptyping
+
+Here \type {z1} is a short way of saying \type {(x1,y1)}. When a \type {z}
+variable is called, the corresponding \type {x} and \type {y} variables are
+available too. Later we will discuss \METAPOST\ capability to deal with
+expressions, which are expressed using an \type {=} instead of \type {:=}. In
+this case the expression related to \type {z0} is expanded into:
+
+\starttyping
+z0 = (x0,y0) = (0.5cm,1.5cm) ;
+\stoptyping
+
+But for this moment let's forget about their expressive nature and simply see
+them as points which we will now connect by straight line segments.
+
+\startuseMPgraphic{path}
+  tmp := "z0--z1--z2--z3--cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+The smooth curved connection, using \type {..} looks like:
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2..z3..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+If we replace the \type {..} by \type {...}, we get a tighter path.
+
+\startuseMPgraphic{path}
+  tmp := "z0...z1...z2...z3...cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Since there are \type {..}, \type {--}, and \type {...}, it will be no surprise
+that there is also \type {---}.
+
+\startuseMPgraphic{path}
+  tmp := "z0---z1---z2---z3---cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+If you compare this graphic with the one using \type {--} the result is the same,
+but there is a clear difference in control points. As a result, combining \type
+{..} with \type {--} or \type {---} makes a big difference. Here we get a
+non||smooth connection between the curves and the straight line.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2--z3..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+As you can see in the next graphic, when we use \type {---}, we get a smooth
+connection between the straight line and the rest of the curve.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2---z3..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+So far, we have joined the four points as one path. Alternatively, we can
+constrict subpaths and connect them using the ampersand symbol, \type {&}.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2 & z2..z3..z0 & cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+So far we have created a closed path. Closing is done by \type {cycle}. The
+following path may look closed but is in fact open.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2..z3..z0" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Only a closed path can be filled. The closed alternative looks as follows. We

+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2..z3..z0..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Here the final \type {..} will try to make a smooth connection, but because we
+already are at the starting point, this is not possible. However, the \type
+{cycle} command can automatically connect to the first point. Watch the
+difference between the previous and the next path.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2..z3..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+It is also possible to combine two paths into one that don't have common head and
+tails. First we define an open path:
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+The following path is a closed one, and crosses the previously shown path.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z3..z1..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+With \type {buildcycle} we can combine two paths into one.
+
+\startuseMPgraphic{path}
+  tmp := "buildcycle(z0..z1..z2 , z0..z3..z1..cycle)" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+We would refer readers to the \METAFONT\ book and the \METAPOST\ manual for an
+explanation of the intricacies of the \type {buildcycle} command. It is an
+extremely complicated command, and there is just not enough room here to do it
+justice. We suffice with saying that the paths should cross at least once before
+the \type {buildcycle} command can craft a combined path from two given paths. We
+encourage readers to experiment with this command.
+
+In order to demonstrate another technique of joining paths, we first draw a few
+strange paths. The last of these three graphics demonstrates the use of \type
+{softjoin}.
+
+\startuseMPgraphic{path}
+  tmp := "z0--z1..z2--z3" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2--z3" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Watch how \type {softjoin} removes a point in the process of smoothing a
+connection. The smoothness is accomplished by adapting the control points of the
+neighbouring points in the appropriate way.
+
+\startuseMPgraphic{path}
+  tmp := "z0--z1 softjoin z2--z3" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Once a path is known, you can cut off a slice of it. We will demonstrate a few
+alternative ways of doing so, but first we show one more time the path that we
+take as starting point.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..z2..z3..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+This path is made up out of five points, where the cycle duplicates the first
+point and connects the loose ends. The first point has number zero.
+
+We can use these points in the \type {subpath} command, which takes two
+arguments, specifying the range of points to cut of the path specified after the
+keyword \type {of}.
+
+\startuseMPgraphic{path}
+  tmp := "subpath(2,4) of (z0..z1..z2..z3..cycle)" ;
+\stopuseMPgraphic

+In spite of what you may think, a point is not fixed. This is why in \METAPOST\ a

+Often we want to take a slice starting at a specific point. This is provided by
+\type {cutafter} and its companion \type {cutbefore}. Watch out, this time we use

+\startuseMPgraphic{path}
+  tmp := "(z0..z1..z2..z3)" ;
+\stopuseMPgraphic

+
+Here is a somewhat silly way of accomplishing the same thing, but it is a nice

+
+\startuseMPgraphic{path}
+  tmp := "(z0..z1..z2..z3) cutbefore point 2 of (z0..z1..z2..z3)" ;
+\stopuseMPgraphic

+
+As with \type {subpath}, you can use fractions to specify the time on the path,
+although the resulting point is not necessarily positioned linearly along the
+curve.
+
+\startuseMPgraphic{path}
+  tmp := "(z0..z1..z2..z3) cutbefore point 2.5 of (z0..z1..z2..z3)" ;
+\stopuseMPgraphic

+
+If you really want to know the details of where fraction points are positioned,
+you should read the \METAFONT\ book and study the source of \METAFONT\ and
+\METAPOST, where you will find the complicated formulas that are used to
+calculate smooth curves.
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..cycle" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+Like any closed path, this path has points where the tangent is horizontal or
+vertical. Early in this chapter we mentioned that a pair (or point) can specify a
+direction or vector. Although any angle is possible, we often use one of four
+predefined directions:
+
+\starttabulate[|Tl|Tl|]
+\HL
+\NC right \NC ( 1, 0) \NC \NR
+\NC up    \NC ( 0, 1) \NC \NR
+\NC left  \NC (-1, 0) \NC \NR
+\NC down  \NC ( 0,-1) \NC \NR
+\HL
+\stoptabulate
+
+We can use these predefined directions in combination with \type {directionpoint}
+and \type {cutafter}. The following command locates the first point on the path
+that has a tangent that points vertically upward, and then feeds this point to
+the \type {cutafter} command.
+
+\startuseMPgraphic{path}
+  tmp := "(z0..z1..cycle) cutafter directionpoint up of (z0..z1..cycle)" ;
+\stopuseMPgraphic
+
+\getbuffer
+
+You are not limited to predefined direction vectors. You can provide a pair to
+indicate a direction. In the next example we use the following cyclic path:
+
+\startuseMPgraphic{path}
+  tmp := "z0..z1..cycle" ;
+\stopuseMPgraphic

+Using \type {( )} is not mandatory but makes the expression look less

+
+Drawing is done by applying the \type {draw} command to a path, as in:
+
+\starttyping
+draw (0cm,1cm)..(2cm,2cm)..(4cm,0cm)..cycle ;
+\stoptyping
+
+The rightmost graphic was made with \type {fill}:
+
+\starttyping
+fill (0cm,1cm)..(2cm,2cm)..(4cm,0cm)..cycle ;
+\stoptyping
+
+If you try to duplicate this drawing, you will notice that you will get black
+lines instead of red and a black fill instead of a gray one. When drawing or
+filling a path, you can give it a color, use all kinds of pens, and achieve
+special effects like dashes or arrows.
+
+\startlinecorrection[blank]
+\startMPcode
+visualizepaths ;
+path p ; p := (0cm,1cm)..(2cm,2cm)..(4cm,0cm)..(2.5cm,1cm)..cycle ;
+drawarrow p withcolor .625red ;
+draw p shifted (7cm,0) dashed withdots withcolor .625yellow ;
+\stopMPcode
+\stoplinecorrection
+
+These two graphics were defined and drawn using the following commands. Later we
+will explain how you can set the line width (or penshape in terms of \METAPOST).
+
+\starttyping
+path p ; p := (0cm,1cm)..(2cm,2cm)..(4cm,0cm)..(2.5cm,1cm)..cycle ;
+drawarrow p withcolor .625red ;
+draw p shifted (7cm,0) dashed withdots withcolor .625yellow ;
+\stoptyping
+
+Once we have drawn one or more paths, we can store them in a picture variable.
+The straightforward way to store a picture is to copy it from the current
+picture:
+
+\starttyping
+picture pic ; pic := currentpicture ;
+\stoptyping
+
+The following command effectively clears the picture memory and allows us to
+start anew.
+
+\starttyping
+currentpicture := nullpicture ;
+\stoptyping
+
+We can shift, rotate and slant the picture stored in \type {pic} as we did with
+paths. We can say:
+
+\starttyping
+draw pic rotated 45 withcolor red ;
+\stoptyping
+
+A picture can hold multiple paths. You may compare a picture to grouping as
+provided by drawing applications.
+
+\starttyping
+draw (0cm,0cm)--(1cm,1cm) ; draw (1cm,0cm)--(0cm,1cm) ;
+picture pic ; pic := currentpicture ;
+draw pic shifted (3cm,0cm) ; draw pic shifted (6cm,0cm) ;
+pic := currentpicture ; draw pic shifted (0cm,2cm) ;
+\stoptyping
+
+We first draw two paths and store the resulting \quote {cross} in a picture
+variable. Then we draw this picture two times, so that we now have three copies
+of the cross. We store the accumulated drawing again, so that after duplication,
+we finally get six crosses.
+
+\startlinecorrection[blank]
+\startMPcode
+path p ; p := (0cm,0cm)--(1cm,1cm) ;
+path q ; q := (1cm,0cm)--(0cm,1cm) ;
+for i=p,q :
+  drawpath i ; drawcontrollines i ; drawpoints i ; drawcontrolpoints i ;
+endfor ;
+picture pic ; pic := currentpicture ;
+draw pic shifted (3cm,0cm) ;
+draw pic shifted (6cm,0cm) ;
+pic := currentpicture ;
+draw pic shifted (0cm,2cm) ;
+\stopMPcode
+\stoplinecorrection
+
+You can often follow several routes to reach the same solution. Consider for
+instance the following graphic.
+
+\startbuffer[points]
+w := 4cm ; h := 2cm ; ww := 1cm ; hh := 1.5cm ;
+\stopbuffer
+
+\startbuffer[common]
+drawoptions(withcolor .625white) ;
+\stopbuffer
+
+\startbuffer[background]
+fill (unitsquare xscaled w yscaled h) enlarged 2mm withcolor .625yellow ;
+\stopbuffer
+
+\startbuffer[shape]
+fill (0,0)--(ww,0)--(ww,hh)--(w,hh)--(w,h)--(0,h)--cycle ;
+fill (ww,0)--(w,0)--(w,hh)--cycle ;
+\stopbuffer
+
+\typebuffer[shape]
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,shape]
+\stoplinecorrection
+
+The points that are used to construct the paths are defined using the constants
+\type {w}, \type {h}, \type {ww} and \type {hh}. These are defined as follows:
+
+\typebuffer[points]
+
+In this case we draw two shapes that leave part of the rectangle uncovered. If
+you have a background, this technique allows the background to \quote {show
+through} the graphic.
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape]
+\stoplinecorrection
+
+A not uncommon practice when making complicated graphics is to use unfill
+operations. Since \METAPOST\ provides one, let us see what happens if we apply
+this command.
+
+\startbuffer[shape]
+fill (0,0)--(w,0)--(w,h)--(0,h)--cycle ;
+unfill (ww,0)--(w,hh)--(ww,hh)--cycle ;
+\stopbuffer
+
+\typebuffer[shape]
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape]
+\stoplinecorrection
+
+This does not always give the desired effect, because \METAPOST's \type {unfill}
+is not really an unfill, but a \type {fill} with color \type {background}. Since
+this color is white by default, we get what we just showed. So, if we set \type
+{background} to \type {black}, using \typ {background := black}, we get:
+
+\startbuffer[back]
+background := black ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[back,common,points,background,shape]
+\stoplinecorrection
+
+Of course, you can set the variable \type {background} to a different color, but
+this does not hide the fact that \METAPOST\ lacks a real unfill operation.
+
+\startbuffer[shape]
+fill (0,0)--(0,h)--(w,h)--(w,0)--(ww,0)--(w,hh)--(ww,hh)--
+     (ww,0)--cycle ;
+\stopbuffer
+
+\startbuffer[path]
+autoarrows := true ;
+path p ; p := (0,0)--(0,h)--(w,h)--(w,0)--(ww,0)--(w,hh)--(ww,hh)--
+  (ww,0)--cycle ;
+draw p withpen pencircle scaled 1mm withcolor .625red;
+numeric l ; l := length(p)-1 ;
+for i=0 upto l :
+ drawarrow subpath(i,i+1) of p
+   withpen pencircle scaled 1mm
+   withcolor (.5+.5(i/l))*red ;
+endfor ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape]
+\stoplinecorrection
+
+Since we don't consider this \type {unfill} a suitable operator, you may wonder
+how we achieved the above result.
+
+\typebuffer[shape]
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape,path]
+\stoplinecorrection
+
+This feature depends on the \POSTSCRIPT\ way of filling closed paths, which comes
+down to filling either the left or the right hand side of a curve. The following
+alternative works too.
+
+\startbuffer[shape]
+fill (0,0)--(0,h)--(w,h)--(w,hh)--(ww,hh)--(ww,0)--(w,hh)--
+     (w,0)--cycle ;
+\stopbuffer
+
+\typebuffer[shape]
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape]
+\stoplinecorrection
+
+The next alternative will fail. This has to do with the change in direction at
+point \type {(0,0)} halfway through the path. Sometimes changing direction can
+give curious but desirable effects, but here it brings no good.
+
+\startbuffer[shape]
+fill (0,0)--(0,h)--(w,h)--(w,0)--(0,0)--(ww,0)--(ww,hh)--
+     (w,hh)--(ww,0)--cycle ;
+\stopbuffer
+
+\typebuffer[shape]
+
+This path fails because of the way \POSTSCRIPT\ implements its fill operator.
+More details on how \POSTSCRIPT\ defines fills can be found in the reference
+manuals.
+
+\startlinecorrection[blank]
+\processMPbuffer[common,points,background,shape]
+\stoplinecorrection
+
+Some of the operations we have seen are hard coded into \METAPOST\ and are called
+primitives. Others are defined as macros, that is, a sequence of \METAPOST\
+commands. Since they are used often, you may expect \type {draw} and \type {fill}
+to be primitives, but they are not. They are macros defined in terms of
+primitives.
+
+Given a path \type {pat}, you can consider a \type {draw} to be defined in terms
+of:
+
+\starttyping
+addto currentpicture doublepath pat
+\stoptyping
+
+The \type {fill} command on the other hand is defined as:
+
+\starttyping
+addto currentpicture contour pat
+\stoptyping
+
+Both macros are actually a bit more complicated but this is mainly due to the
+fact that they also have to deal with attributes like the pen and color they draw
+with.
+
+You can use \type {doublepath} and \type {contour} directly, but we will use
+\type {draw} and \type {fill} whenever possible.
+
+Given a picture \type {pic}, the following code is valid:
+
+\starttyping
+addto currentpicture also pic
+\stoptyping
+
+You can add pictures to existing picture variables, where \type {currentpicture}
+is the picture that is flushed to the output file. Watch the subtle difference
+between adding a \type {doublepath}, \type {contour} or \type {picture}.
+
+\stopsection
+
+\startsection[title={Variables}]
+
+\index{variables}
+
+At this point you may have noted that \METAPOST\ is a programming language.
+Contrary to some of today's languages, \METAPOST\ is a simple and clean language.
+Actually, it is a macro language. Although \METAPOST\ and \TEX\ are a couple, the
+languages differ in many aspects. If you are using both, you will sometimes wish
+that features present in one would be available in the other. When using both
+languages, in the end you will understand why the conceptual differences make
+sense.
+
+Being written in \PASCAL, it will be no surprise that \METAPOST\ has some
+\PASCAL||like features, although some may also recognize features from \ALGOL68\
+in it.
+
+First there is the concept of variables and assignments. There are several data
+types, some of which we already have seen.
+
+\starttabulate
+\HL
+\NC numeric \NC real number in the range $-4096 \ldots +4096$          \NC \NR
+\NC boolean \NC a variable that takes one of two states: true or false \NC \NR
+\NC pair    \NC point or vector in 2||dimensional space                \NC \NR
+\NC path    \NC a piecewise collection of curves and line segments     \NC \NR
+\NC picture \NC collection of stroked or filled paths                  \NC \NR
+\NC string  \NC sequence of characters, like \type {"metapost"}        \NC \NR
+\NC color   \NC vector of three (rgb) or four (cmyk) numbers           \NC \NR
+\HL
+\stoptabulate
+
+There are two additional types, \type {transform} and \type {pen}, but we will
+not discuss these in depth.
+
+\starttabulate
+\HL
+\NC transform \NC transformation vector with six elements \NC \NR
+\NC pen       \NC pen specification                       \NC \NR
+\HL
+\stoptabulate
+
+You can achieve interesting effects by using pens with certain shapes. For the
+moment you may consider a pen to be a path itself that is applied to the path
+that is drawn.
+
+The \type {numeric} data type is used so often that it is the default type of any
+non declared variable. This means that
+
+\starttyping
+n := 10 ;
+\stoptyping
+
+is the same as
+
+\starttyping
+numeric n ; n := 10 ;
+\stoptyping
+
+When writing collections of macros, it makes sense to use the second method,
+because you can never be sure if \type {n} isn't already declared as a picture
+variable, and assigning a numeric to a picture variable is not permitted.
+
+Because we often deal with collections of objects, such as a series of points,
+all variables can be organized in arrays. For instance:
+
+\starttyping
+numeric n[] ; n[3] := 10 ; n[5] := 13 ;
+\stoptyping
+
+An array is a collection of variables of the same type that are assigned and
+accessed by indexing the variable name, as in \type {n[3] := 5}.
+Multi||dimensional arrays are also supported. Since you need a bit of imagination
+to find an application for 5||dimensional arrays, we restrict ourselves to a
+two||dimensional example.
+
+\starttyping
+numeric n[][] ; n[2][3] := 10 ;
+\stoptyping
+
+A nice feature is that the bounds of such an array needs not to be set
+beforehand. This also means that each cell that you access is reported as {\em
+unknown} unless you have assigned it a value.
+
+Behind the screens there are not really arrays. It's just a matter of creating
+hash entries. It might not be obvious, but the following assignments are all
+equivalent:
+
+\startbuffer
+i_111_222     := 1cm ;
+i_[111]_[222] := 1cm ;
+i_[111][222]  := 1cm ;
+draw
+    image (
+        draw (0cm,i_111_222) ;
+        draw (1cm,i_[111]_[222]) ;
+        draw (2cm,i_[111][222]) ;
+    )
+    withpen pencircle scaled 5mm
+    withcolor .625 red ;
+\stopbuffer
+
+\typebuffer
+
+Sometimes \METAPOST\ ways are mysterious:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+\stopsection
+
+\startsection[title={Conditions}]
+
+\index{conditions}
+
+The existence of boolean variables indicates the presence of conditionals.
+Indeed, the general form of \METAPOST's conditional follows:
+
+\starttyping
+if n=10 : draw p ; else : draw q ; fi ;
+\stoptyping
+
+Watch the colons after the if and else clause. They may not be omitted. The
+semi||colons on the other hand, are optional and depend on the context. You may
+say things like:
+
+\starttyping
+draw if n=10 : p ; else : q ; fi ;
+\stoptyping
+
+Here we can omit a few semi||colons:
+
+\starttyping
+draw if n=10 : p else : q fi withcolor red ;
+\stoptyping
+
+Adding semi||colons after \type {p} and \type {q} will definitely result in an
+error message, since the semi||colon ends the draw operation and \typ {withcolor
+red} becomes an isolated piece of nonsense.
+
+There is no case statement available, but for most purposes, the following
+extension is adequate:
+
+\starttyping
+draw p withcolor if n<10 : red elseif n=10 : green else : blue fi ;
+\stoptyping
+
+There is a wide repertoire of boolean tests available.
+
+\starttyping
+if picture p :
+if known   n :
+if odd     i :
+if cycle   q :
+\stoptyping
+
+Of course, you can use \type {and}, \type {or}, \type {not}, and \type {( )} to
+construct very advanced boolean expressions. If you have a bit of programming
+experience, you will appreciate the extensive support of conditionals in
+\METAPOST.
+
+\stopsection
+
+\startsection[title={Loops}]
+
+\index{loops}
+
+Yet another programming concept present in \METAPOST\ is the loop statement, the
+familiar \quote {for loop} of all programming languages.
+
+\starttyping
+for i=0 step 2 until 20 :
+  draw (0,i) ;
+endfor ;
+\stoptyping
+
+As explained convincingly in Niklaus Wirth's book on algorithms and
+datastructures, the for loop is the natural companion to an array. Given an array
+of length $n$, you can construct a path out of the points that make up the array.
+
+\starttyping
+draw for i=0 step 1 until n-1 : p[i] .. endfor p[n] ;
+\stoptyping
+
+If the step increment is not explicitly stated, it has an assumed value of 1. We
+can shorten the previous loop construct as follows:
+
+\starttyping
+draw for i=0 upto n-1 : p[i] .. endfor p[n] ;
+\stoptyping
+
+After seeing \type {if} in action, the following \type {for} loop will be no
+surprise:
+
+\startbuffer
+draw origin for i=0 step 10 until 100 : ..{down}(i,0) endfor ;
+\stopbuffer
+
+\typebuffer
+
+This gives the zig||zag curve:
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+You can use a loop to iterate over a list of objects. A simple 3||step iteration
+is:
+
+\starttyping
+for i=p,q,r :
+  fill i withcolor .8white ;
+  draw i withcolor red ;
+endfor ;
+\stoptyping
+Using \type {for} in this manner can sometimes save a bit of typing. The list can
+contain any expression, and may be of different types.
+
+In the previous example the \type {i} is an independent variable, local to the
+for loop. If you want to change the loop variable itself, you need to use \type
+{forsuffixes}. In the next loop the paths \type {p}, \type {q} and~\type {r} are
+all shifted.
+
+\starttyping
+forsuffixes i = p, q, r :
+  i := i shifted (3cm,2cm) ;
+endfor ;
+\stoptyping
+
+Sometimes you may want to loop forever until a specific condition occurs. For
+this, \METAPOST\ provides a special looping mechanism:
+
+\startbuffer[demo]
+numeric done[][], i, j, n ; n := 0 ;
+forever :
+  i := round(uniformdeviate(10)) ; j := round(uniformdeviate(2)) ;
+  if unknown done[i][j] :
+    drawdot (i*cm,j*cm) ; n := n + 1 ; done[i][j] := n ;
+  fi ;
+  exitif n = 10 ;
+endfor ;
+\stopbuffer
+
+\typebuffer[demo]
+
+Here we remain in the loop until we have 10 points placed. We use an array to
+keep track of placed points. The \METAPOST\ macro \type {uniformdeviate(n)}
+returns a random number between 0 and~n and the \type {round} command is used to
+move the result toward the nearest integer. The \type {unknown} primitive allows
+us to test if the array element already exists, otherwise we exit the
+conditional. This saves a bit of computational time as each point is drawn and
+indexed only once.
+
+\startbuffer[pen]
+pickup pencircle scaled 2mm ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[pen,demo]
+\stoplinecorrection
+
+The loop terminator \type {exitif} and its companion \type {exitunless} can be
+used in \type {for}, \type {forsuffixes} and \type {forever}.
+
+\stopsection
+
+\startsection[title={Macros}]
+
+\index{macros}
+\index{definitions}
+
+In the previous section we introduced \type {upto}. Actually this is not part of
+the built in syntax, but a sort of shortcut, defined by:
+
+\starttyping
+def upto = step 1 until enddef ;
+\stoptyping
+
+You just saw a macro definition where \type {upto} is the name of the macro. The
+counterpart of \type {upto} is \type {downto}. Whenever you use \type {upto}, it
+is replaced by \typ {step 1 until}. This replacement is called expansion.
+
+There are several types of macros. A primary macro is used to define your own
+operators. For example:
+
+\starttyping
+primarydef p doublescaled s =
+  p xscaled (s/2) yscaled (s*2)
+enddef ;
+\stoptyping
+
+Once defined, the \type {doublescaled} macro is implemented as in the following
+example:
+
+\starttyping
+draw somepath doublescaled 2cm withcolor red ;
+\stoptyping
+
+When this command is executed, the macro is expanded. Thus, the actual content of
+this command becomes:
+
+\starttyping
+draw somepath xscaled 1cm yscaled 4cm withcolor red ;
+\stoptyping
+
+If in the definition of \type {doublescaled} we had added a semi||colon after
+\type {(s*2)}, we could not have set the color, because the semicolon ends the
+statement. The \type {draw} expects a path, so the macro can best return one.
+
+A macro can take one or more arguments, as in:
+
+\starttyping
+def drawrandomscaledpath (expr p, s) =
+  draw p xscaled (s/2) yscaled (s*2) ;
+enddef ;
+\stoptyping
+
+When using this macro, it is expected that you will pass it two parameters, the
+first being a path, the second a numeric scale factor.
+
+\starttyping
+drawrandomscaledpath(fullsquare, 3cm) ;
+\stoptyping
+
+Sometimes we want to return a value from a macro. In that case we must make sure
+that any calculations don't interfere with the expectations. Consider:
+
+\starttyping
+vardef randomscaledpath(expr p, s) =
+  numeric r ; r := round(1 + uniformdeviate(4)) ;
+  p xscaled (s/r) yscaled (s*r)
+enddef ;
+\stoptyping
+
+Because we want to use the same value of \type {r} twice, we have to use an
+intermediate variable. By using a \type {vardef} we hide everything but the last
+statement. It is important to distinguish \type {def} macros from those defined
+with \type {vardef}. In the latter case, \type {vardef} macros are not a simple
+expansion and replacement. Rather, \type {vardef} macros return the value of
+their last statement. In the case of the \type {randomscaledpath} macro, a path
+is returned. This macro is used in the following manner:
+
+\starttyping
+path mypath ; mypath := randomscaledpath(unitsquare,4cm) ;
+\stoptyping
+
+Note that we send \type {randomscaledpath} a path (\type {unitsquare}) and a
+scaling factor (\type {4cm}). The macro returns a scaled path which is then
+stored in the path variable \type {mypath}.
+
+The following argument types are accepted:
+
+\starttabulate
+\HL
+\NC expr   \NC something that can be assigned to a variable      \NC \NR
+\NC text   \NC arbitrary \METAPOST\ code ending with a \type {;} \NC \NR
+\NC suffix \NC a variable bound to another variable              \NC \NR
+\HL
+\stoptabulate
+An expression is passed by value. This means that in the body of the macro, a
+copy is used and the original is left untouched. On the other hand, any change to
+a variable passed as suffix is also applied to the original.
+
+Local variables must be handled in a special manner, since they may conflict with
+variables used elsewhere. This is because all variables are global by default.
+The way out of this problem is using grouping in combination with saving
+variables. The use of grouping is not restricted to macros and may be used
+anywhere in your code. Variables saved and declared in a group are local to that
+group. Once the group is exited the variables cease to exist.
+
+\starttyping
+vardef randomscaledpath(expr p, s) =
+  begingroup ; save r ; numeric r ;
+    r := round(1 + uniformdeviate(4)) ;
+    p xscaled (s/r) yscaled (s*r)
+  endgroup
+enddef ;
+\stoptyping
+
+In this particular case, we could have omitted the grouping, since \type {vardef}
+macros are always grouped automatically. Therefore, we could have defined the
+macro as:
+
+\starttyping
+vardef randomscaledpath(expr p, s) =
+  save r ; numeric r ; r := round(1 + uniformdeviate(4)) ;
+  p xscaled (s/r) yscaled (s*r)
+enddef ;
+\stoptyping
+
+The command \type {save r} declares that the variable \type {r} is local to the
+macro. Thus, any changes to the (new) numeric variable \type {r} are local and
+will not interfere with a variable \type {r} defined outside the macro. This is
+important to understand, as variables outside the macro are global and accessible
+to the code within the body of the macro.
+
+Macro definitions may be nested, but since most \METAPOST\ code is relatively
+simple, it is seldom needed. Nesting is discouraged as it makes your code less
+readable.
+
+Besides \type {def} and \type {vardef}, \METAPOST\ also provides the classifiers
+\type {primarydef}, \type {secondarydef} and \type {tertiarydef}. You can use
+these classifiers to define macros like those provided by \METAPOST\ itself:
+
+\starttyping
+primarydef   x mod               y = ... enddef ;
+secondarydef p intersectionpoint q = ... enddef ;
+tertiarydef  p softjoin          q = ... enddef ;
+\stoptyping
+A primary macro acts like the binary operators \type {*} or \type {scaled} and
+\type {shifted}. Secondary macros are like \type {+}, \type {-} and logical \type
+{or}, and take less precedence. The tertiary operators like \type {<} or the path
+and string concatenation operator \type {&} have tertiary macros as companions.
+More details can be found in the \METAFONT\ book. When it comes to taking
+precedence, \METAPOST\ tries to be as natural as possible, in the sense that you
+need to provide as few \type {( )}'s as possible. When in doubt, or when
+surprised by unexpected results, use parentheses.
+
+\stopsection
+
+\startsection[title={Arguments}]
+
+\index{arguments}
+\index{macros+arguments}
+
+The \METAPOST\ macro language is rather flexible in how you feed arguments to
+macros. If you have only one argument, the following definitions and calls are
+valid.
+
+\starttyping
+def test  expr a  = enddef ; test (a) ; test a ;
+def test (expr a) = enddef ; test (a) ; test a ;
+\stoptyping
+
+A more complex definition is the following. As you can see, you can call the
+\type {test} macro in your favorite way.
+
+\starttyping
+def test (expr a,b) (expr c,d) = enddef ;
+
+test (a) (b) (c) (d) ;
+test (a,b) (c,d) ;
+test (a,b,c) (d) ;
+test (a,b,c,d) ;
+\stoptyping
+
+The type of the arguments is one of \type {expr}, \type {primary} or \type
+{suffix}. When fetching arguments, \METAPOST\ uses the type to determine how and
+what to grab. A fourth type is \type {text}. When no parenthesis are used, a
+\type {text} argument grabs everything upto the next semicolon.
+
+\starttyping
+def test (expr a) text b = enddef ;
+
+test (a) ; test (a) b ;
+\stoptyping
+
+You can use a \type {text} to grab arguments like \typ {withpen pencircle scaled
+10 withcolor red}. Because \type {text} is so hungry, you may occasionally need a
+two stage definition:
+
+\starttyping
+def test    expr a         = dotext(a) enddef ;
+def dotest (expr a) text b = ...       enddef ;
+
+test a ; test a b ;
+\stoptyping
+
+This definition permits arguments without parenthesis, which is something you
+want with commands like \type {draw}.
+
+The \type {vardef} alternative behaves in a similar way. It always provides
+grouping. You need to generate a return value and as a result may not end with a
+semicolon.
+
+You may consider the whole \type {vardef} to be encapsulated into parenthesis and
+thereby to be a (self contained) variable. Adding additional parenthesis often
+does more harm than good:
+
+\starttyping
+vardef test (expr a) =
+  ( do tricky things with a ; manipulated_a )
+enddef ;
+\stoptyping
+
+Here the tricky things become part of the return value, which quite certainly is
+something that you don't want.
+
+The three operator look||alike macro definitions are less flexible and have the
+definition scheme:
+
+\starttyping
+primarydef   x test y = enddef ;
+secondarydef x test y = enddef ;
+tertiarydef  x test y = enddef ;
+\stoptyping
+
+When defining macros using this threesome you need to be aware of the associated
+priorities. When using these definitions, you also have to provide your own
+grouping.
+
+In the plain \METAPOST\ macro collection (\type {plain.mp}) you can find many
+examples of clever definitions. The following (simplified) version of \type {min}
+demonstrates how we use the argument handler to isolate the first argument from
+the provided list, simply by using two arguments.
+
+\starttyping
+vardef min (expr u) (text t) =
+  save min_u ; min_u := u ;
+  for uu = t : if uu<u : min_u := uu ; fi endfor
+  min_u
+enddef ;
+\stoptyping
+
+The special sequence \type {@#} is used to pick up a so called delimited argument:
+
+\starttyping
+vardef TryMe@#(expr x) =
+  % we can now use @#, which is just text
+enddef ;
+\stoptyping
+
+This feature is used in the definition of \type {z} as used in \type {z1} or
+\type {z234}:
+
+\starttyping
+vardef z@# = (x@#,y@#) enddef ;
+\stoptyping
+
+Other applications can be found in the label drawing macros where the anchor
+point is assigned to the obscure variable \type {@#}.
+
+\stopsection
+
+\startsection[title={Pens}]
+
+\index{pens}
+
+When drawing, three attributes can be applied to it: a dashpattern, a pen
+and|/|or a color. You may consider an arrowhead an attribute, but actually it is
+just an additional drawing, appended to the path.
+
+The (predefined) \type {pencircle} attribute looks like:
+
+\starttyping
+withpen pencircle
+\stoptyping
+
+where \type {pencircle} is a special kind of path, stored in a pen variable. Like
+any path, you can transform it. You can scale it equally in all directions:
+
+\starttyping
+withpen pencircle scaled 1mm
+\stoptyping
+
+You can also provide unequal scales, creating an elliptically shaped and rotated
+pen.
+
+\starttyping
+withpen pencircle xscaled 2mm yscaled 4mm rotated 30
+\stoptyping
+
+In the following graphic, the circle in the center is drawn without any option,
+which means that the default pen is used, being a pencircle with a radius of half
+a base point. The other three circles are drawn with different pen
+specifications.
+
+\startlinecorrection[blank]
+\startMPcode

+drawoptions (withcolor .625red) ;
+draw p scaled 4 withpen pencircle xscaled 2mm yscaled 4mm rotated 30 ;
+\stopMPcode
+\stoplinecorrection
+
+If you forget about the colors, the \METAPOST\ code to achieve this is as
+follows.
+
+\starttyping
+path p ; p := fullcircle scaled 1cm ;
+draw p ;
+draw p scaled 2 withpen pencircle ;
+draw p scaled 3 withpen pencircle scaled 1mm ;
+draw p scaled 4 withpen pencircle xscaled 2mm yscaled 4mm rotated 30 ;
+\stoptyping
+
+If this were the only way of specifying a pen, we would be faced with a
+considerable amount of typing, particularly in situations where we use pens
+similar to the fourth specification above. For that reason, \METAPOST\ supports
+the concept of a current pen. The best way to set this pen is to use the \type
+{pickup} macro.
+
+\starttyping
+pickup pencircle xscaled 2mm yscaled 4mm rotated 30 ;
+\stoptyping
+
+This macro also stores some characteristics of the pen in variables, so that they
+can be used in (the more complicated) calculations that are involved in
+situations like drawing font||like graphics.
+
+If we substitute \type {pencircle} by \type {pensquare}, we get a different kind
+of shapes. In the non rotated pens, the top, bottom, left and right parts of the
+curve are thinner.
+
+\startlinecorrection[blank]
+\startMPcode
+path p ; p := fullcircle scaled 1cm ;
+drawoptions (withcolor .625yellow) ;

+\stopMPcode
+\stoplinecorrection
+
+You should look at pens in the way an artist does. He follows a shape and in
+doing so he or she twists the pen (and thereby the nib) and puts more or less
+pressure on it.
+
+The chance that you have an appropriate pen laying at your desk is not so big,
+but you can simulate the following \METAPOST's pen by taking two pencils and
+holding them together in one hand. If you position them in a 45 degrees angle,
+and draw a circle, you will get something like:
+
+\startlinecorrection[blank]
+\startMPcode
+path p ; p := fullcircle xscaled 2cm yscaled 3cm ;
+drawoptions(withcolor .625red withpen pencircle scaled .5mm);
+draw p ; draw p shifted (.3cm,.3cm) ;
+\stopMPcode
+\stoplinecorrection
+
+If you take a calligraphic pen with a thin edge of .5cm, you will get:
+
+\startlinecorrection[blank]
+\startMPcode
+drawoptions(withcolor .625red);
+path p ; p := fullcircle xscaled 2cm yscaled 3cm ;
+draw p withpen makepen ((0,0)--(.3cm,.3cm)) withcolor .625white ;
+drawoptions(withcolor .625red withpen pencircle scaled .25mm);
+draw p ; draw p shifted (.3cm,.3cm) ;
+\stopMPcode
+\stoplinecorrection
+
+You can define such a pen yourself:
+
+\starttyping
+path p ; p := fullcircle xscaled 2cm yscaled 3cm ;
+pen doublepen ; doublepen := makepen ((0,0)--(.3cm,.3cm)) ;
+pickup doublepen ; draw p ;
+\stoptyping
+
+Here we define a new pen using the \type {pen} command. Then we define a path,
+and make a pen out of it using the \type {makepen} macro. The path should be a
+relatively simple one, otherwise \METAPOST\ will complain.
+
+You can use \type {makepen} with the previously introduced \type {withpen}:
+
+\starttyping
+draw p withpen makepen ((0,0)--(.3cm,.3cm)) ;
+\stoptyping
+
+and \type {pickup}:
+
+\starttyping
+pickup makepen ((0,0)--(.3cm,.3cm)) ; draw p ;
+\stoptyping
+
+You can use \type {makepen} and \type {makepath} to convert paths into pens and
+vice versa.
+
+Pens are very important when defining fonts, and \METAFONT\ is meant to be a font
+creation tool. Since \METAPOST\ has a slightly different audience, it lacks some
+features in this area, but offers a few others instead. Nevertheless, one can try
+to design a font using \METAPOST. Of course, pens are among the designers best
+kept secrets. But even then, not every~O is a nice looking one.

+\startsection[title={Colors}]
+
+\index{attributes}
+\index{color}
+So far, we have seen some colors in graphics. It must be said that \METAPOST\
+color model is not that advanced, although playing with colors in the \METAPOST\
+way can be fun. In later chapters we will discuss some extensions that provide
+shading.
+
+Colors are defined as vectors with three components: a red, green and blue one.
+Like pens, colors have their \type {with}||command:
+
+\starttyping
+withcolor (.4,.5.,6)
+\stoptyping
+
+You can define color variables, like:
+
+\starttyping
+color darkred ; darkred := (.625,0.0) ;
+\stoptyping
+
+You can now use this color as:
+
+\starttyping
+withcolor darkred
+\stoptyping
+
+Given that \type {red} is already defined, we also could have said:
+
+\starttyping
+withcolor .625red
+\stoptyping
+
+Because for \METAPOST\ colors are just vectors, you can do things similar to
+points. A color halfway red and green is therefore accomplished with:
+
+\starttyping
+withcolor .5[red,green]
+\stoptyping
+
+Since only the \RGB\ color space is supported, this is about all we can tell
+about colors for this moment. Later we will discuss some nasty details.
+
+\stopsection
+
+\startsection[title={Dashes}]
+
+\index{dashes}
+
+A dash pattern is a simple picture that is build out of straight lines. Any
+slightly more complicated picture will be reduced to straight lines and a real
+complicated one is rejected, and in this respect \METAPOST\ considers a circle to
+be a complicated path.
+
+The next example demonstrates how to get a dashed line. First we built picture
+\type {p}, that we apply to a path. Here we use a straight path, but dashing can
+be applied to any path.
+
+\startbuffer
+picture p ; p := nullpicture ;
+addto p doublepath ((0,0)--(3mm,3mm)) shifted (6mm,6mm) ;
+draw (0,0)--(10cm,0) dashed p withpen pencircle scaled 1mm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+This way of defining a pattern is not that handy, especially if you start
+wondering why you need to supply a slanted path. Therefore, \METAPOST\ provides a
+more convenient mechanism to define a pattern.
+
+\startbuffer
+picture p ; p := dashpattern(on 3mm off 3mm) ;
+draw (0,0)--(10cm,0) dashed p withpen pencircle scaled 1mm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Most dashpatterns can be defined in terms of on and off. This simple on||off
+dashpattern is predefined as picture \type {evenly}. Because this is a picture,
+you can (and often need to) scale it.
+
+\startbuffer
+draw (0,0)--(10cm,0) dashed (evenly scaled 1mm)
+  withpen pencircle scaled 1mm ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+Opposite to a defaultpen, there is no default color and default dash pattern set.
+The macro \type {drawoptions} provides you a way to set the default attributes.

+\startsection[reference=sec:text,title={Text}]
+
+\index{text}
+
+Since \METAFONT\ is meant for designing fonts, the only means for including text
+are those that permit you to add labels to positions for the sole purpose of
+documentation.
+
+Because \METAPOST\ is derived from \METAFONT\ it provides labels too, but in
+order to let users add more sophisticated text, like a math formula, to a
+graphic, it also provides an interface to \TEX.
+
+Because we will spend a whole chapter on using text in \METAPOST\ we limit the
+discussion here to a few fundamentals.

+\stopbuffer
+
+\typebuffer[label]
+
+These four labels show up at the position stored in the pair variable \type {a},
+anchored in the way specified after the period.
+
+\startlinecorrection[blank]
+\processMPbuffer[font,label]
+\stoplinecorrection
+
+The command \type {dotlabel} also typesets the point as a rather visible dot.
+

+dotlabel.top("top",a) ; dotlabel.bot("bot",a) ;

+drawdot a withcolor .625yellow ;
+draw thelabel.rt("the right way",a) withcolor .625red ;
+\stopbuffer
+
+\typebuffer[label]
+
+You can of course rotate, slant and manipulate such a label picture like any
+other picture.
+
+\startlinecorrection[blank]
+\processMPbuffer[font,label]
+\stoplinecorrection
+
+The font can be specified in the string \type {defaultfont} and the scale in
+\type {defaultscale}. Labels are defined using the low level operator \type
+{infont}. The next statement returns a picture:
+
+\startbuffer[mp]
+draw "this string will become a sequence of glyphs (MP)"
+  infont defaultfont scaled defaultscale ;
+\stopbuffer
+
+\typebuffer[mp]
+
+By default the \type {infont} operator is not that clever and does not apply
+kerning. Also, typesetting math or accented characters are not supported. The way
+out of this problem is using \typ {btex ... etex}.
+
+\startbuffer[tex]
+draw btex this string will become a sequence of glyphs (\TeX) etex ;
+\stopbuffer
+
+\typebuffer[tex]
+
+The difference between those two methods is shown below. The outcome of \type
+{infont} depends on the current setting of the variable \type {defaultfont}.
+
+\startlinecorrection[blank]
+\processMPbuffer[mp]
+\processMPbuffer[tex]
+\stoplinecorrection
+
+When you run inside \CONTEXT\ (as we do here) there is no difference between
+\type {infont} and the \TEX\ methods. This is because we overload the \type
+{infont} operator and also pass its content to \TEX. Both \type {infont} and
+\type {btex} use the macro \type {textext} which is intercepted and redirects the
+task to \TEX. This happens in the current run so there is no need to pass extra
+information about fonts.
+
+Instead of passing strings to \type {infont}, you can also pass characters, using
+\type {char}, for example \type {char(73)}. When you use \type {infont} you
+normally expect the font to be \ASCII\ conforming. If this is not the case, you
+must make sure that the encoding of the font that you use matches your
+expectations. However, as we overload this macro it does not really matter since
+the string is passed to \TEX\ anyway. For instance, \UTF\ encoded text should
+work fine as \CONTEXT\ itself understands this encoding.

+
+In the previous sections, we used the assignment operator \type {:=} to assign a
+value to a variable. Although for most of the graphics that we will present in
+later chapters, an assignment is appropriate, specifying a graphic in terms of
+expressions is not only more flexible, but also more in the spirit of the
+designers of \METAFONT\ and \METAPOST.
+
+The \METAFONT\ book and \METAPOST\ manual provide lots of examples, some of which
+involve math that we don't consider to belong to everyones repertoire. But, even
+for non mathematicians using expressions can be a rewarding challenge.
+
+The next introduction to linear equations is based on my first experiences with
+\METAPOST\ and involves a mathematical challenge posed by a friend. I quickly
+ascertained that a graphical proof was far more easy than some proof with a lot
+of $\sin (this)$ and $\cos (that)$ and long forgotten formulas.
+
+I was expected to prove that the lines connecting the centers of four squares
+drawn upon the four sides of a quadrilateral were perpendicular (see \in {figure}
+[fig:problem]).
+
+\getbuffer[a,b,c,d,e]
+
+\getbuffer[f]
+
+This graphic was generated with the following command:
+
+\typebuffer[f]
+
+We will use this example to introduce a few new concepts, one being instances. In
+a large document there can be many \METAPOST\ graphics and they might fall in
+different categories. In this manual we have graphics that are generated as part
+of the style as wel as examples that show what \METAFUN\ can do. As definitions
+and variables in \METAPOST\ are global by default, there is a possibility that we
+end up with clashes. This can be avoided by grouping graphics in instances. Here
+we create an instance for the example that we're about to show.
+
+\typebuffer[a]
+
+We can now limit the scope of definitions to this specific instance. Let's start
+with the macro that takes care of drawing the solution to our problem. The macro
+accepts four pairs of coordinates that determine the central quadrilateral. All
+of them are expressions.
+
+\typebuffer[b]
+
+Because we want to call this macro more than once, we first have to save the
+locally used values. Instead of declaring local variables, one can hide their use
+from the outside world. In most cases variables behave globally. If we don't save
+them, subsequent calls will lead to errors due to conflicting equations. We can
+omit the grouping commands, because we wrap the graphic in a figure, and figures
+are grouped already.
+
+We will use the predefined \type {z} variable, or actually a macro that returns a
+variable. This variable has two components, an \type {x} and \type {y}
+coordinate. So, we don't save \type {z}, but the related variables \type {x} and
+\type {y}.
+
+Next we draw four squares and instead of hard coding their corner points, we use
+\METAPOST's equation solver. Watch the use of \type {=} which means that we just
+state dependencies. In languages like \PERL, the equal sign is used in
+assignments, but in \METAPOST\ it is used to express relations.
+
+In a first version, we will just name a lot of simple relations, as we can read
+them from a sketch drawn on paper. So, we end up with quite some \type {z}
+related expressions.
+
+For those interested in the mathematics behind this code, we add a short
+explanation. Absolutely key to the construction is the fact that you traverse the
+original quadrilateral in a clockwise orientation. What is really going on here
+is vector geometry. You calculate the vector from $z_{11}$ to $z_{12}$ (the first
+side of the original quadrilateral) with:
+
+\starttyping
+(a,b) = z12 - z11 ;
+\stoptyping
+
+This gives a vector that points from $z_{11}$ to $z_{12}$. Now, how about an
+image that shows that the vector $(-b,a)$ is a 90 degree rotation in the
+counterclockwise direction. Thus, the points $z_{13}$ and $z_{14}$ are easily
+calculated with vector addition.
+
+\starttyping
+z13 = z12 + (-b,a) ;
+z14 = z11 + (-b,a) ;
+\stoptyping
+
+This pattern continues as you move around the original quadrilateral in a
+clockwise manner. \footnote {Thanks to David Arnold for this bonus explanation.}
+
+The code that calculates the pairs \type {a} through \type {h}, can be written in
+a more compact way.
+
+\starttyping
+(a,b) = z12 - z11 ; (c,d) = z22 - z21 ;
+(e,f) = z32 - z31 ; (g,h) = z42 - z41 ;
+\stoptyping
+
+The centers of each square can also be calculated by \METAPOST. The next lines
+define that those points are positioned halfway the extremes.
+
+\starttyping
+z1 = 0.5[z11,z13] ; z2 = 0.5[z21,z23] ;
+z3 = 0.5[z31,z33] ; z4 = 0.5[z41,z43] ;
+\stoptyping
+
+Once we have defined the relations we can let \METAPOST\ solve the equations.
+This is triggered when a variable is needed, for instance when we draw the
+squares and their diagonals. We connect the centers of the squares using a dashed
+line style.
+
+Just to be complete, we add a symbol that marks the right angle. First we
+determine the common point of the two lines, that lays at {\em whatever} point
+\METAPOST\ finds suitable.
+
+The definition of \type {mark_rt_angle} is copied from the \METAPOST\ manual and
+shows how compact a definition can be (see \at {page} [zscaled] for an
+introduction to \type {zscaled}).
+
+\typebuffer[c]
+
+So far, most equations are rather simple, and in order to solve them, \METAPOST\
+did not have to work real hard. The only boundary condition is that in order to
+find a solution, \METAPOST\ must be able to solve all dependencies.
+
+The actual value of the \type {whatever} variable is that it saves us from
+introducing a slew of variables that will never be used again. We could write:
+
+\starttyping
+z0 = A[z1,z3] = B[z2,z4] ;
+\stoptyping
+
+and get the same result, but the \type {whatever} variable saves us the trouble
+of introducing intermediate variables for which we have no use once the
+calculation is finished.
+
+The macro \type{mark_rt_angle} draws the angle symbol and later we will see how
+it is defined. First we draw the labels. Unfortunately we cannot package \typ
+{btex ... etex} into a macro, because it is processed in a rather special way.
+Each \typ {btex ... etex} occurance is filtered from the source and converted
+into a snippet of \TEX\ code. When passed through \TEX, each snippet becomes a
+page, and an auxiliary program converts each page into a \METAPOST\ picture
+definition, which is loaded by \METAPOST. The limitation lays in the fact that
+the filtering is done independent from the \METAPOST\ run, which means that loops
+(and other code) are not seen at all. Later we will introduce the \METAFUN\ way
+around this.
+
+In order to get all the labels typeset, we have to put a lot of code here. The
+macro \type {dotlabel} draws a dot and places the typeset label.
+
+\typebuffer[d]
+
+Watch out: as we are in \CONTEXT, we can pass regular \TEX\ code to the label
+macro. In a standalone \METAPOST\ run you'd have to use the \type {btex} variant.
+
+We are going to draw a lot of pictures, so we define an extra macro. This time we
+hard||code some values. The fractions \type {i} and \type {j} are responsible for
+the visual iteration process, while \type {s} determines the labels. We pass
+these variables to the graphic using an extra argument. When you define the
+(useable) graphic you need to tell what variables it can expect.
+
+\typebuffer[e]
+
+Of course we could have used a loop construct here, but defining auxiliary macros
+probably takes more time than simply calling the drawing macro directly. The
+results are shown on a separate page (\in{figure}[fig:solution]).

+
+It does not need that much imagination to see the four sided problem converge to
+a three sided one, which itself converges to a two sided one. In the two sided
+alternative it's not that hard to prove that the angle is indeed 90 degrees.
+
+As soon as you can see a clear pattern in some code, it's time to consider using
+loops. In the previous code, we used semi indexes, like \type {12} in \type
+{z12}. In this case \type{12} does reflect something related to square~1 and~2,
+but in reality the 12 is just twelve. This does not harm our expressions.
+
+A different approach is to use a two dimensional array. In doing so, we can
+access the variables more easily using loops. If we omit the labels, and angle
+macro, the previously defined macro can be reduced considerably.

+
+For applications that do something with a drawing, for instance \TEX\ embedding a

+The maximum dimensions of a graphic are specified by its bounding box.

+
+A bounding box is defined by its lower left and upper right corners. If you open
+the \POSTSCRIPT\ file produced by \METAPOST, you may find lines like:
+
+\starttyping
+%%BoundingBox: -46 -46 46 46

+or, when supported,
+
+\starttyping
+%%HiResBoundingBox: -45.35432 -45.35432 45.35432 45.35432
+\stoptyping
+
+The first two numbers define the lower left corner and the last two numbers the
+upper right corner. From these values, you can calculate the width and height of
+the graphic.
+
+A graphic may extend beyond its bounding box. It depends on the application that
+uses the graphic whether that part of the graphic is shown.
+
+In \METAPOST\ you can ask for all four points of the bounding box of a path or
+picture as well as the center.

+
+We will now encounter a couple of transformations that can make your life easy
+when you use \METAPOST\ for making graphics like the ones demonstrated in this
+document. These transformations are not part of standard \METAPOST, but come with
+\METAFUN.
+
+A very handy extension is \type {enlarged}. Although you can feed it with any
+path, it will return a rectangle larger or smaller than the boundingbox of that
+path. You can specify a pair or a numeric.
+
+\startbuffer

+
+There are a few more alternatives, like \type {bottomenlarged}, \type
+{rightenlarged}, \type {topenlarged} and \type {leftenlarged}.
+
+The \type {cornered} operator will replace sharp corners by rounded ones (we
+could not use \type {rounded} because this is already in use).
+
+\startbuffer
+path p ; p := ((1,0)--(2,0)--(2,2)--(1,2)--(0,1)--cycle)

+drawpath p ; drawpoints p ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+The \type {smoothed} operation is a less subtle one, since it operates on the
+bounding box and thereby can result in a different shape.
+
+\startbuffer
+path p ; p := ((1,0)--(2,0)--(2,2)--cycle) xysized (4cm,2cm) ;

+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+The next one, \type {simplified}, can be applied to paths that are constructed
+automatically. Instead of testing for duplicate points during construction, you
+can clean up the path afterwards.
+
+\startbuffer
+path p ; p :=
+  ((0,0)--(1,0)--(2,0)--(2,1)--(2,2)--(1,2)--(0,2)--(0,1)--cycle)

+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+A \type {punked} path is, like a punked font, a font with less smooth curves (in

+
+\startbuffer

+A \type {curved} path on the other hand has smooth connections. Where in many

+

+If you use a negative argument (like \type {-1cm}) the parallel line will be

+give a square round corners with \type {roundedsquare}:
+
+\startbuffer
+path p ; p := roundedsquare(2cm,4cm,.25cm) ;
+drawpath p ; drawpoints p ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+Next we draw a square|-|like circle (or circle|-|like square) using \type
+{tensecircle}:
+
+\startbuffer
+path p ; p := tensecircle(2cm,4cm,.25cm) ;
+drawpath p ; drawpoints p ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+Often I make such helpers in the process of writing larger drawing systems. Take
+\type {crossed}:
+
+\startbuffer
+path p ; p := origin crossed 1cm ;
+drawpath p ; drawpoints p ;
+p := (origin crossed fullcircle scaled 2cm crossed .5cm) shifted (3cm,0) ;
+drawpath p ; drawpoints p ;
+\stopbuffer
+
+\typebuffer
+
+These examples demonstrate that a path is made up out of points (something that
+you probably already knew by now). The \METAPOST\ operator \type {of} can be used
+to \quote {access} a certain point at a curve.
+
+\startbuffer
+path p ; p := fullsquare xyscaled (3cm,2cm) randomized .5cm ;
+drawpath p ; drawpoints p ; drawpointlabels p ;
+draw point 2.25 of p withpen pencircle scaled 5mm withcolor .625red ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+To this we add two more operators: \type {on} and \type {along}. With \type {on}
+you get the point at the supplied distance from point~0; with \type {along} you
+get the point at the fraction of the length of the path.
+
+\startbuffer
+path p, q, r ;
+p := fullsquare xyscaled (2cm,2cm) randomized .5cm ;
+q := p shifted (3cm,0) ; r := q shifted (3cm,0) ;
+drawpath p ; drawpoints p ; drawpointlabels p ;
+drawpath q ; drawpoints q ; drawpointlabels q ;
+drawpath r ; drawpoints r ; drawpointlabels r ;
+pickup pencircle scaled 5mm ;
+draw point 2.25   of    p withcolor .625red ;
+draw point 2.50cm on    q withcolor .625yellow ;
+draw point  .45   along r withcolor .625white ;
+\stopbuffer
+
+\typebuffer
+
+Beware: the \type {length} of a path is the number of points minus one. The
+shapes below are constructed from 5~points and a length of~4. If you want the
+length as dimension, you should use \type {arclength}.
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+We will now play a bit with simple lines. With \type {cutends}, you can (indeed)
+cut off the ends of a curve. The specification is a dimension.
+
+\startbuffer
+path p ; p := (0cm,0cm)        -- (4cm,1cm) ;
+path q ; q := (5cm,0cm){right} .. (9cm,1cm) ;
+drawpath p ; drawpoints p ; drawpath q ; drawpoints q ;
+p := p cutends .5cm ; q := q cutends .5cm ;
+drawpathoptions (withpen pencircle scaled 5pt withcolor .625yellow) ;
+drawpointoptions(withpen pencircle scaled 4pt withcolor .625red) ;
+drawpath p ; drawpoints p ; drawpath q ; drawpoints q ;
+resetdrawoptions ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+As with more operators, \type {cutends} accepts a numeric or a pair. Watch the
+subtle difference between the next and the previous use of \type {cutends}.
+
+\startbuffer
+path p ; p := (0cm,0) .. (4cm,0) .. (8cm,0) .. (4cm,0) .. cycle ;
+drawpath p ; drawpoints p ; p := p cutends (2cm,1cm) ;
+drawpathoptions (withpen pencircle scaled 5pt withcolor .625yellow) ;
+drawpointoptions(withpen pencircle scaled 4pt withcolor .625red) ;
+drawpath p ; drawpoints p ;
+resetdrawoptions ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+When \type {stretched} is applied to a path, it is scaled but the starting point
+(point~0) keeps its location. The specification is a scale.
+
+\startbuffer
+path p ; p := (0cm,0) .. (3cm,1cm) .. (4cm,0) .. (5cm,1cm) ;
+drawpath p ; drawpoints p ; p := p stretched 1.1 ;
+drawpathoptions (withpen pencircle scaled 2.5pt withcolor .625yellow) ;
+drawpointoptions(withpen pencircle scaled 4.0pt withcolor .625red) ;
+drawpath p ; drawpoints p ; resetdrawoptions ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+We can scale in two directions independently or even in one direction by
+providing a zero value. In the next example we apply the stretch two times.
+
+\startbuffer
+path p ; p := (0cm,0) .. (3cm,1cm) .. (4cm,0) .. (5cm,1cm) ;
+drawpath p ; drawpoints p ; p := p stretched (.75,1.25) ;
+drawpathoptions (withpen pencircle scaled 2.5pt withcolor .625yellow) ;
+drawpointoptions(withpen pencircle scaled 4.0pt withcolor .625red) ;
+drawpath p ; drawpoints p ; p := p stretched (0,1.5) ;
+drawpathoptions (withpen pencircle scaled 4.0pt withcolor .625red) ;
+drawpointoptions(withpen pencircle scaled 2.5pt withcolor .625yellow) ;
+drawpath p ; drawpoints p ; resetdrawoptions ;
+\stopbuffer
+
+\typebuffer
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+We already met the \type {randomize} operator. This one is the chameleon under
+the operators.
+
+\startbuffer
+draw fullsquare xyscaled (4cm,2cm)
+  randomized .25cm
+  shifted origin randomized (1cm, 2cm)
+  withcolor red randomized (.625, .850)
+  withpen pencircle scaled (5pt randomized 1pt) ;
+\stopbuffer
+
+\typebuffer
+
+So, \type {randomized} can handle a numeric, pair, path and color, and its
+specification can be a numeric, pair or color, depending on what we're dealing
+with.
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+In the previous example we also see \type {xyscaled} in action. Opposite to \type
+{scaled}, \type {xscaled} and \type {yscaled}, this is not one of \METAPOST\
+build in features. The same is true for the \type {.sized} operators.
+
+\startbuffer[a]
+picture p ; p := image
+  ( draw fullsquare
+      xyscaled (300,800)
+      withpen pencircle scaled 50
+      withcolor .625 yellow ; ) ;
+draw p xysized (3cm,2cm) shifted (bbwidth(currentpicture)+.5cm,0) ;
+draw p xysized  2cm      shifted (bbwidth(currentpicture)+.5cm,0) ;
+draw p xsized   1cm      shifted (bbwidth(currentpicture)+.5cm,0) ;
+draw p ysized   2cm      shifted (bbwidth(currentpicture)+.5cm,0) ;
+\stopbuffer
+
+\typebuffer[a]
+
+\startlinecorrection[blank] \processMPbuffer[a] \stoplinecorrection
+
+Here, the \type {image} macro creates an (actually rather large) picture. The
+last four lines actually draw this picture, but at the given dimensions. Watch
+how the line width scales accordingly. If you don't want this, you can add the
+following line:
+
+\startbuffer[b]
+redraw currentpicture withpen pencircle scaled 2pt ;
+draw boundingbox currenpicture withpen pencircle scaled .5mm ;
+\stopbuffer
+
+\typebuffer[b]
+
+Watch how the boundingbox is not affected:
+
+\startlinecorrection[blank] \processMPbuffer[a,b] \stoplinecorrection
+
+In this example we also used \type {bbwidth} (which has a companion macro \type
+{bbheight}). You can apply this macro to a path or a picture.
+
+In fact you don't always need to follow this complex route if you want to simply
+redraw a path with another pen or color.
+
+\startbuffer
+draw fullcircle scaled 1cm
+  withcolor .625red    withpen pencircle scaled 1mm ;
+draw currentpicture
+  withcolor .625yellow withpen pencircle scaled 3mm ;
+draw boundingbox currentpicture
+  withpen pencircle scaled .5mm ;
+\stopbuffer
+
+\typebuffer
+
+This is what you will get from this:
+
+\startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+If you want to add a background color to a picture you can do that afterwards.
+This can be handy when you don't know in advance what size the picture will have.
+
+\startbuffer
+fill fullcircle scaled 1cm withcolor .625red ;
+addbackground withcolor .625 yellow ;
+\stopbuffer
+
+\typebuffer
+
+The background is just a filled rectangle that gets the same size as the current
+picture, that is put on top of it.

+\startsection[title={Cutting and pasting}]
+
+\index{paths+cutting}
+\index{cutting}
+
+When enhancing or building a graphic, often parts of already constructed paths
+are needed. The \type {subpath}, \type {cutbefore} and \type {cutafter} operators
+can be used to split paths in smaller pieces. In order to do so, we must know
+where we are on the path that is involved. For this we use points on the path.
+Unfortunately we can only use these points when we know where they are located.
+In this section we will combine some techniques discussed in previous sections.
+We will define a few macros, manipulate some paths and draw curves and points.
+
+\startbuffer
+path p ; p := fullcircle yscaled 3cm xscaled .9TextWidth ;
+drawpath p ; drawpoints p withcolor .625red ; drawpointlabels p ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+This circle is drawn by scaling the predefined path \type {fullcircle}. This path
+is constructed using 8~points. As you can see, these points are not distributed
+equally along the path. In the following graphic, the second and third point of
+the curve are colored red, and point 2.5 is colored yellow. Point~0 is marked in
+black. This point is positioned halfway between point~2 and~3.
+
+\startbuffer
+path p ; p := fullcircle scaled 3cm xscaled 2 ;
+pickup pencircle scaled 5mm ; autoarrows := true ;
+drawarrow         p withcolor .625white ;
+draw point 0.0 of p ;
+draw point 2.0 of p withcolor .625red ;
+draw point 2.5 of p withcolor .625yellow ;
+draw point 3.0 of p withcolor .625red ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+It is clear that, unless you know exactly how the path is constructed, other
+methods should be available. A specific point on a path is accessed by \typ
+{point ... of}, but the next example demonstrates two more alternatives.
+
+\startbuffer
+path p ; p := fullcircle scaled 3cm xscaled 2 ;
+pickup pencircle scaled 5mm ;
+draw                 p withcolor .625white ;
+draw point 3   of    p withcolor .625red ;
+draw point .6  along p withcolor .625yellow ;
+draw point 3cm on    p ;
+\stopbuffer
+
+\typebuffer
+
+So, in addition to \type {on} to specify a point by number (in \METAPOST\
+terminology called time), we have \type {along} to specify a point as fraction of
+the path, and \type {on} to specify the position in a dimension.
+
+\startlinecorrection[blank]
+\processMPbuffer
+\stoplinecorrection
+
+The \type {on} and \type {along} operators are macros and can be defined as:
+
+\starttyping
+primarydef len on pat =
+  (arctime len of pat) of pat
+enddef ;
+
+primarydef pct along pat =
+  (arctime (pct * (arclength pat)) of pat) of pat
+enddef ;
+\stoptyping
+
+These macros introduce two new primitives, \type {arctime} and \type {arclength}.
+While \type {arctime} returns a number denoting the time of the point on the
+path, \type {arclength} returns a dimension.
+
+\quotation {When mathematicians draw parametric curves, they frequently need to
+indicate the direction of motion. I often have need of a little macro that will
+put an arrow of requested length, anchored at a point on the curve, and bending
+with the curve in the direction of motion.}
+
+When David Arnold asked me how this could be achieved, the fact that a length was
+requested meant that the solution should be sought in using the primitives and
+macros we introduced a few paragraphs before. Say that we want to call for such
+an arrow as follows.
+
+\startbuffer[a]
+path p ; p := fullcircle scaled 3cm ;
+pair q ; q := point .4 along p ;
+pickup pencircle scaled 2mm ;
+draw                p        withcolor .625white ;
+drawarrow somearrow(p,q,2cm) withcolor .625red ;
+draw                  q      withcolor .625yellow ;
+\stopbuffer
+
+\typebuffer[a]
+
+Because we want to follow the path, we need to construct the arrow from this
+path. Therefore, we first reduce the path by cutting off the part before the
+given point. Next we cut off the end of the resulting path so that we keep a
+slice that has the length that was asked for. Since we can only cut at points, we
+determine this point using the \type {arctime} primitive.
+
+\startbuffer[b]
+vardef somearrow (expr pat, loc, len) =
+  save p ; path p ; p := pat cutbefore loc ;
+  (p cutafter point (arctime len of p) of p)
+enddef ;
+\stopbuffer
+
+\typebuffer[b]
+
+By using a \type {vardef} we hide the intermediate assignments. Such \type
+{vardef} is automatically surrounded by \type {begingroup} and \type {endgroup},
+so the \type {save} is local to this macro. When processed, this code produces
+the following graphic:
+
+\startbuffer[c]
+autoarrows := true ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[c,b,a]
+\stoplinecorrection
+
+This graphic shows that we need a bit more control over the exact position of the
+arrow. It would be nice if we could start the arrow at the point, or end there,
+or center the arrow around the point. Therefore, the real implementation is a bit
+more advanced.
+
+\startbuffer
+vardef pointarrow (expr pat, loc, len, off) =
+  save l, r, s, t ; path l, r ; numeric s ; pair t ;
+  t := if pair loc : loc else : point loc along pat fi ;
+  s := len/2 - off ; if s<=0 : s := 0 elseif s>len : s := len fi ;
+  r := pat cutbefore t ;
+  r := (r cutafter point (arctime s of r) of r) ;
+  s := len/2 + off ; if s<=0 : s := 0 elseif s>len : s := len fi ;
+  l := reverse (pat cutafter t) ;
+  l := (reverse (l cutafter point (arctime s of l) of l)) ;
+  (l..r)
+enddef ;
+\stopbuffer
+
+\typebuffer
+
+This code fragment also demonstrates how we can treat the \type {loc} argument as
+pair (coordinates) or fraction of the path. We calculate the piece of path before
+and after the given point separately and paste them afterwards as \type {(l..r)}.
+By adding braces we can manipulate the path in expressions without the danger of
+handling \type {r} alone.
+
+We can now implement left, center and right arrows by providing this macro the
+right parameters. The offset (the fourth parameter), is responsible for a
+backward displacement. This may seem strange, but negative values would be even
+more confusing.
+
+\startbuffer
+def rightarrow (expr p,t,l) = pointarrow(p,t,l,-l) enddef ;
+def leftarrow  (expr p,t,l) = pointarrow(p,t,l,+l) enddef ;
+def centerarrow(expr p,t,l) = pointarrow(p,t,l, 0) enddef ;
+\stopbuffer
+
+\typebuffer
+
+We can now apply this macro as follows:
+
+\startbuffer[a]
+path p ; p := fullcircle scaled 3cm ;
+pickup pencircle scaled 2mm ;
+draw p withcolor .625white ;
+drawarrow leftarrow  (p,     .4     ,2cm) withcolor .625red ;
+drawarrow centerarrow(p,point 5 of p,2cm) withcolor .625yellow ;
+draw point .4 along p withcolor .625yellow ;
+draw point  5 of    p withcolor .625red ;
+\stopbuffer
+
+\typebuffer[a]
+
+\startlinecorrection[blank]
+\processMPbuffer[a]
+\stoplinecorrection
+
+Watch how we can pass a point (\typ {point 5 of p}) as well as a fraction (\type
+{.4}). The following graphic demonstrates a few more alternatives.
+
+\startbuffer[a]
+pickup pencircle scaled 2mm; autoarrows := true ;
+
+path p ; p := fullcircle yscaled 3cm xscaled .9TextWidth ;
+
+draw p withcolor .5white;
+
+for i=1, 2, 3 :
+  drawdot point i of p withpen pencircle scaled 5mm withcolor .625white ;
+endfor ;
+for i=.60, .75, .90 :
+  drawdot point i along p withpen pencircle scaled 5mm withcolor .625white ;
+endfor ;
+\stopbuffer
+
+\startbuffer[b]
+drawarrow leftarrow   (p,point 1 of p,2cm) withcolor red     ;
+drawarrow centerarrow (p,point 2 of p,2cm) withcolor blue    ;
+drawarrow rightarrow  (p,point 3 of p,2cm) withcolor green   ;
+drawarrow pointarrow  (p,.60,4cm,+.5cm)    withcolor yellow  ;
+drawarrow pointarrow  (p,.75,3cm,-.5cm)    withcolor cyan    ;
+drawarrow centerarrow (p,.90,3cm)          withcolor magenta ;
+\stopbuffer
+
+\startlinecorrection[blank]
+\processMPbuffer[a,b]
+\stoplinecorrection
+
+The arrows are drawn using the previously defined macros. Watch the positive and
+negative offsets in call to \type {pointarrow}.
+
+\typebuffer[b]
+
+\stopsection
+
+\startsection[title={Current picture}]
+
+\index {pictures}
+
+When you draw paths, texts and|/|or pictures they are added to the so called
+current picture. You can manipulate this current picture as is demonstrated in
+this manual. Let's show a few current picture related tricks.
+
+\startbuffer
+  draw fullcircle scaled 1cm withpen pencircle scaled 1mm withcolor .625red ;
+\stopbuffer
+
+\typebuffer \startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+We can manipulate the picture as a whole:
+
+\startbuffer
+  draw fullcircle scaled 1cm withpen pencircle scaled 1mm withcolor .625red ;
+  currentpicture := currentpicture slanted .5 ;
+\stopbuffer
+
+\typebuffer \startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+Sometimes it's handy to temporarily set aside the current picture.
+
+\startbuffer
+  draw fullcircle scaled 1cm withpen pencircle scaled 1mm withcolor .625red ;
+  currentpicture := currentpicture slanted .5 ;
+  pushcurrentpicture ;
+  draw fullcircle scaled 1cm withpen pencircle scaled 1mm withcolor .625yellow ;
+  currentpicture := currentpicture slanted -.5 ;
+  popcurrentpicture ;
+\stopbuffer
+
+\typebuffer \startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+These are \METAFUN\ commands but \METAPOST\ itself comes with a variant, \type
+{image}, and you explicitly have to draw this picture (or otherwise add it to the
+currentpicture).
+
+\startbuffer
+  draw fullcircle scaled 1cm withpen pencircle scaled 1mm withcolor .625red ;
+  currentpicture := currentpicture slanted .5 ;
+  draw image (
+    draw fullcircle scaled 1cm
+        withpen pencircle scaled 1mm withcolor .625yellow ;
+    currentpicture := currentpicture slanted -.5 ;
+  ) ;
+\stopbuffer
+
+\typebuffer \startlinecorrection[blank] \processMPbuffer \stoplinecorrection
+
+Each graphic starts fresh with an empty current picture. In \METAFUN\ we make
+sure that we also reset some otherwise global variables, like color, pen and some
+line properties.

+% comment   : Because this manual is distributed with TeX distributions it comes with a rather
+%             liberal license. We try to adapt these documents to upgrades in the (sub)systems
+%             that they describe. Using parts of the content otherwise can therefore conflict
+%             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   : A prototype of the nodes module was presented at the ConTeXt 2016 user meeting
+%             and the first release was presented at the 2017 meeting. The module is part of
+%             the MetaFun code modules.
+%
+% comment   : This manual orginates in an article by Alan so anything wrong in here is Hans
+%             fault as he converted it.
+%
+% comment   : It is also being published as an article in TugBoat.
+%
+% comment   : The cover images are from the NASA website.
+
+
+% Alan      : There is no need for % before \startfootnote .. the less such crap the better
+%             (as it might give disappearing content if one wraps).
+%
+% Alan      : ḻṯ  What is this? An editor glitch?
+%
+% Alan      : $≠$ -> just use ≠ (also, soon the gyre fonts will have more symbols in text
+%             that match text.
+%
+% Alan      : You can use \typ {x = 0} for something that breaks accross lines.

+
+The graphical representation of textual diagrams is a very useful tool in the
+communication of ideas. In category and topos theory, for example, many key
+concepts, formulas, and theorems are expressed by means of \emph {commutative
+diagrams}; these involve objects and arrows between them. Certain concepts
+discovered by category theory, such as \emph {natural transformations}, are
+becoming useful in areas outside of mathematics and natural science, e.g., in
+philosophy. To make category and topos methods usable by both specialists and
+non|-|specialists, commutative diagrams are an indispensable tool.
+\startfootnote
+    For many examples of formal and informal commutative diagrams, see \cite
+    [authoryears] [Lawvere2009].
+\stopfootnote
+The use of nodal diagrams is not limited to category theory, for they may
+represent a flow diagram (of a process, for example), a chemical reaction
+sequence or pathways, or that of phases and phase transitions, a hierarchical
+structure (of anything), a timeline or sequence of events or dependencies, a tree
+of descendance or ascendance, etc.
+
+The basic units of a node|-|based diagram include \emph {node objects}, each
+attached to some point (= the \emph {node}) in some spatial relationship. Note
+that to a single node might be associated a set of objects. Given a node, it also
+stands in a spatial relation to some other node. The spatial relationship between
+the set of nodes of a diagram need not be in a regular network, although they
+quite often are. Note that the spatial relationship between nodes is graphical
+and may represent, e.g., a temporal or logical relationship, or a transformation
+of one object into another or into others (one interesting example might be that
+representing cell division or, mitosis).
+
+Given a spatial relation between any two nodes, a node|-|based diagram often
+includes some \emph {path segment} or segments (such as arrows or other curves)
+between two given nodes that \emph {relates} them. Each path segment may be
+augmented by some textual or graphical label.
+
+A very simple example of a node diagram is shown in \in{Figure} [fig:AB].

+
+More precisely, a \emph {node} is a point of intersection or branching of paths,
+often a point on a regular lattice. (The nodes of the above diagram are the two
+endpoints of a straight line segment.) Sometimes, however, a node might be a
+single point as in an \emph {identity map} of category theory, referring to
+itself:
+\startfootnote
+    The standard arrowhead in \METAPOST\ is a simple triangle, whose length and
+    angle can be adjusted. \METAFUN\ provides further options, allowing this
+    arrowhead to be barbed or dimpled. In the present article, we use the
+    settings: \type {ahlength := EmWidth ; ahangle := 30 ; ahvariant := 1 ;
+    ahdimple := 4/5 ;} The loop|-|back arrow paths used here deviate from a
+    circular segment, becoming ellipsoidal, through the value \type
+    {node_loopback_yscale := .7 ;} These are all set, of course, between a \type
+    {\startMPinitializations} … \type {\stopMPinitializations} pair.

+
+In this article we discuss a new \METAPOST\ module designed for handling
+node|-|based graphics as well as a derivative simple \CONTEXT\ interface. To

+\CONTEXT\ interface and/or want to draw more advanced diagrams, the \METAPOST\
+module is much more powerful and flexible.

+
+\METAPOST\ is a vector|-|graphics language which calls upon \TeX\ to typeset text
+(such as labels); in \CONTEXT, furthermore, \METAPOST\ is integrated natively
+through the library MPlib as well as the macro package \METAFUN. The tight
+integration of \CONTEXT\ and \METAPOST\ provides advantages over the use of
+other, external graphics engines. These advantages include ease of maintaining
+coherence of style, as well as extensive flexibility without bloat. \METAPOST\
+has further advantages over most other graphics engines, including a very high
+degree of precision as well as the possibility to solve certain types of
+algebraic equations. This last feature is rarely used but should not be
+overlooked.
+
+It is quite natural in \METAPOST\ to locate our node objects along a path or on
+differing paths. This is a much more powerful concept than merely locating a node
+at some pair of coordinates, e.g., on a square or a rectangular lattice, for
+example (as in a table). Furthermore, these paths may be in three dimensions (or
+more); of course the printed page will only involve some projection onto two
+dimensions. Nor are the nodes restricted to location on the points defining a
+path: they may have, as index, any \emph {time} along a given path \type {p}
+ranging from the first defining point ($t = 0$) up to the last point of that path
+($t ≤ \mathtt {length(p)}$), the number of defining points of a path.
+\startfootnote
+    Note that the time of a cyclic path is taken modulo the length of the path,
+    that is $t$ outside of the range $[\mathtt0,\mathtt{length(p)}]$ will return
+    the first or the last point of an open path, but will \quotation {wrap} for a
+    closed path.
+\stopfootnote
+
+Given a path \type {p}, nodes are defined (implicitly) as \type {picture}
+elements: \type {picture p.pic[] ;} This is a pseudo|-|array where the square
+brackets indicates a set of numerical tokens, as in \type {p.pic[0]} or \type
+{p.pic[i]} (for \type {i=0}), but also \type {p.pic0}. This number need not be an
+integer, and \type {p.pic[.5]} or \type {p.pic.5} (not to be confused with \type
+{p.pic5}) are also valid. These picture elements are taken to be located relative
+to the path \type {p}, with the index \type {t} corresponding to a time along the
+path, as in \type {draw p.pic[t] shifted point t of p;} (although it is not
+necessary to draw them in this way). This convention allows the nodes to be
+oriented and offset with respect to the path in an arbitrary manner.
+
+Note that a path can be defined, then nodes placed relative to this path. Or the
+path may be declared but remain undefined, to be determined only after the nodes
+are declared. In yet another possibility, the path may be adjusted as needed, as
+a function of whatever nodes are to be occupied. This will be illustrated through
+examples further down.

+\startaside
+In working with \METAPOST, it is good practice to reset or clear a variable using
+the directive \type {save} for the \emph {suffix} (or variable name) \type
+{nodepath} contained in the directive \type {clearnodepath} (defined as
+\quotation {\type {save nodepath ; path nodepath}}). The macros used here rely on
+the creation of certain internal variables and may not function correctly if the
+variable structure is not cleared. Indeed, any node may contain a combination of
+picture elements, added successively, so it is very important to \type {save} the
+variable, making its use local, rather than global. This point is particularly
+true with \CONTEXT, where a single MPlib instance is used and maintained over
+multiple runs.
+
+The \CONTEXT\ directives \type {\startMPcode} … \type {\stopMPcode} include
+grouping (\METAPOST\ \type {begingroup ;}… \type {endgroup ;}) and the use of
+\type {save} (in \type {clearnodepath}) will make the suffix \type {nodepath}
+local to this code block. In the code for \in{Figures} [fig:square] and \in
+[fig:natural], the path \type {p} itself is not declared local (through the use
+of a \type {save}); it therefore remains available for other \METAPOST\ code
+blocks. We cannot do this with the default suffix name \type {nodepath} without
+undesired consequences.
+
+The directive \type {clearnodepath} used in the example above, much like the
+\METAPOST\ command \type {clearxy} clearing the \type {(x,y)} pair also known as
+\type {z}, uses \type {save} to clear the default suffix \type {nodepath}.
+\stopaside
+
+Note that one should not confuse the \METAPOST\ function \type {node()} with the
+\CONTEXT\ command \type {\node{}}, defined as follows:
+
+\starttwo
+  \startTEX
+  \defineframed
+    [node]
+    [frame=off,
+     offset=1pt]
+  \stopTEX
+\two
+  \startTEX
+  \defineframed
+    [nodeSmall]
+    [node]
+    [foregroundstyle=small]
+  \stopTEX
+\stoptwo
+
+\type {\node{}} places the text within a \CONTEXT\ frame (with the frame border
+turned|-|off), whereas the \METAPOST\ function \type {node(i,"…")} sets and
+returns a picture element associated with a point on path \type {nodepath}
+indexed by its first argument. The second argument here is a string that gets
+typeset by \TEX. (The use of \type {\node{}} adds an \type {offset}).
+
+By default, the \METAPOST\ function \type {fromto()} returns a path segment going
+between two points of the path \type {nodepath}. The first argument (\type {0} in
+the example above) can be used as a displacement to skew the path away from a
+straight line (by an amount in units of the straight path length). The last
+argument is a string to be typeset and placed midpoint of the segment. The
+{suffix} appended to the function name gives an offset around this halfway point.
+This follows standard \METAPOST\ conventions.
+
+It is important to draw or declare the nodes \emph {before} drawing the
+connections, using \type {fromto()}, in order to be able to avoid overlapping
+symbols, as one notices that the arrows drawn in the example above begin and end
+on the border of the frame (or bounding box) surrounding the node text. This
+would of course not be possible if the arrow were to be drawn before this text
+was known.
+
+As will be seen further on, one can actually specify the use of any defined path,
+without restriction to the built|-|in name \type {nodepath} that is used by
+default. Furthermore, a function \type {fromtopaths()} can be used to draw
+segments connecting any two paths which may be distinct. This too will be
+illustrated further on.
+
+The \CONTEXT\ syntax for the current example looks like this:

+This follows the more classic (and limited) approach of placing nodes on the
+coordinates of a regular lattice, here defined as a 3~cm square network.
+\footnote {The lattice can be square (\type {dx} $=$ \type {dy}), rectangular
+(\type {dx} $≠$ \type {dy}), or oblique (through \type {rotation} $≠$ 90).} The
+arguments are then $(x,y)$ coordinates of this lattice and the nodes are indexed
+0, 1, 2, … in the order that they are drawn. These are used as reference indices
+in the commands \type {\connectnodes} (rather than requiring two \emph {pairs} of
+coordinates); see \in {Figure} [fig:indices]. This might seem a bit confusing at
+first view, but it simplifies things in the end, really!
+
+An identity map, as shown in \in {Figure} [fig:ID], earlier, and, below, in \in

+
+For a somewhat more complicated example, let us consider the representation of a

+[Krebs1946] The input is shown coming into the cycle from the center of a circle;
+the products of the cycle are spun|-|off from the outside of the circle. We start
+by defining a circular path where each point corresponds to a step in the cyclic
+process. Our example will use six steps (see \in {Figure} [fig:circles]).
+
+We also want to define a second circular path with the same number of points at
+the interior of this first circle for the input, and a third circular path at the
+exterior for the output.
+
+The code is as follows:
+
+\page [yes]

+
+Nodes will then be drawn on each of these three circles and arrows will be used
+to connect these various nodes, either on the same path or else between paths.
+
+The \METAPOST\ function \type {fromto()} is used to give a path segment that
+points from one node to another. It \emph {assumes} the path \type {nodepath},
+and in fact calls the function \type {fromtopaths} that explicitly takes path
+names as arguments. That is, \type {fromto (d, i, j, …)} is equivalent to \type
+{fromtopaths (d, nodepath, i, nodepath, j, …)}.
+
+As stated above, this segment can be a straight line or else a path that can be
+bowed|-|away from this straight line by a transverse displacement given by the
+function's first argument (given in units of the straight segment length). When
+both nodes are located on a single, defined path, this segment can be made to lie
+on or follow this path, such as one of the circular paths defined above. This
+behavior is obtained by using any non|-|numeric value (such as \type {true}) in
+place of the first argument. Of course, this cannot work if the two nodes are not
+located on the same path.
+
+The circular arc segments labeled \emph {\darkgreen a–f} are drawn on \in

+An \quote {array} of paths is declared through \type {path p[] ;} it is not a
+formal array, but rather a syntactic definition of a collection of path variables
+\type {p0}, \type {p1}, … each of whose name is prefixed with the tag \quotation
+{p} followed by any number, not necessarily an integer (e.g., \type {p3.14} is a
+valid path name). The syntax allows enclosing this \quotation {index} within
+square brackets, as in \type {p[0]} or, more typically, \type {p[i]}, where \type
+{i} would be a numeric variable or the index of a loop. Note that the use of
+brackets is required when using a negative index, as in \type {p[-1]} (for \type
+{p-1} is interpreted as three tokens, representing a subtraction). Furthermore,
+the variable \type {p} itself, would here be a numeric (by default), so \type
+{p[p]} would be a valid syntactic construction! One could, additionally, declare
+a set of variables \type {path p[][] ;} and so forth, defining also \type
+{p[0][0]} (equivalently, \type {p0 0}) for example as a valid path, coexisting
+with yet different from the path \type {p0}.
+
+\METAPOST\ also admits variable names reminiscent of a structure: \type {picture
+p.pic[] ;} for example is used internally in the \type {node} macros, but this
+becomes \type {picture p[]pic[] ;} when using a path \quote {array} syntax. These
+variable names are associated with the suffix \type {p} and become all undefined

+
+Ultimately, one can do better by allowing \METAPOST\ to solve the relevant
+equations and to determine this spacing automatically. Because it is a somewhat
+advanced procedure, this approach will be first illustrated through a very simple
+example of a diagram where the nodes will be placed on a declared but undefined
+path:
+
+\startTEX
+save p ; % path p ;
+\stopTEX
+
+The \type {save p ;} assures that the path is undefined. This path will later ḻṯ
+defined based on the contents of the nodes and a desired relative placement. In
+fact, it is not even necessary to declare that the suffix will be a path, as the
+path will be declared and automatically built once the positions of all the nodes
+are determined. To emphasize this point, the \type {path} declaration above is
+commented|-|out.
+
+\startdescription {Warning:}
+Solving equations in \METAPOST\ can be non|-|trivial for those who are less
+mathematically inclined. One needs to establish a coupled set of equations that
+is solvable: that is, fully but not over|-|determined.
+\stopdescription
+
+A few helper functions have been defined: \type {makenode()} returns a suffix
+(variable name) corresponding to the node's position. The first such node can be
+placed at any finite point, for example the drawing's origin. The following nodes
+can be placed in relation to this first node:
+
+% \startframed [frame=off,align=text,offset=overlay] % keep this together on one page.
+\startTEX
+save nodepath ;
+save first, second, third, fourth ;
+pair first, second, third, fourth ;
+first.i  = 0 ; first  = makenode(first.i, "\node{first}") ;
+second.i = 1 ; second = makenode(second.i,"\node{second}") ;
+third.i  = 2 ; third  = makenode(third.i, "\node{third}") ;
+fourth.i = 3 ; fourth = makenode(fourth.i,"\node{fourth}") ;
+
+first  = origin ;
+second = first
+       + betweennodes.urt(nodepath,first.i, nodepath,second.i,whatever) ;
+third  = second
+       + betweennodes.lft(nodepath,second.i,nodepath,third.i, whatever) ;
+fourth = third
+       + betweennodes.bot(nodepath,fourth.i,nodepath,first.i,3ahlength) ;
+\stopTEX
+% \stopframed
+
+The helper function \type {betweennodes()} returns a vector pointing in a certain
+direction, here following the standard \METAPOST\ suffixes: \type {urt}, \type
+{lft}, and \type {bot}, that takes into account the bounding boxes of the
+contents of each node, plus an (optional) additional distance (here given in
+units of the arrow|-|head length, \type {ahlength}). Using the keyword \type
+{whatever} tells \METAPOST\ to adjust this distance as necessary. The above set
+of equations is incomplete as written, so a fifth and final relation needs to be
+added; the fourth node is also to be located directly to the left of the very
+first node:
+\startfootnote
+    Equivalently, we could declare that the first node located to the right of
+    the fourth node: \type {first = fourth + betweennodes.rt (nodepath, first.i,
+    nodepath, fourth.i, 3ahlength) ;}
+\stopfootnote
+
+\startTEX
+fourth = first
+       + betweennodes.lft(nodepath,fourth.i,nodepath,first.i,3ahlength) ;
+\stopTEX
+
+Note that the helper function \type {makenode()} can be used as many times as
+needed; if given no content, only returning the node's position. Additional nodes
+can be added to this diagram along with appropriate relational equations, keeping
+in mind that the equations must, of course, be solvable. This last issue is the
+one challenge that most users might face. The function \type {node()} that was
+used previously and returning a picture element to be drawn itself calls the
+function \type {makenode()}, used here. The nodes have not yet been drawn:
+

+
+This results in \in {Figure} [fig:relative]. The path is now defined as one

+
+Using this approach, that of defining but not drawing the nodes until a complete

+several limitations. First, the nodes are expected to be numbered from $0$ up to
+$n$, continuously and without any gaps for each defined path. This is just an
+implicit, heuristic convention of the path construction. Second, when finally
+defining all the nodes and their positions, the path needs to be constructed. A
+function, \type {makenodepath(p) ;} accomplishes this; it gets implicitly called
+(once) upon the drawing of any \type {node()} or connecting \type {fromto}. Of
+course, \type {makenodepath()} can always be called explicitly once the set of
+equations determining the node positions is completely defined.
+
+\startparagraph [style=bold]
+We once again stress that the writing of a solvable yet not over|-|determined set
+of equations can be a common source of error for many \METAPOST\ users.
+\startfootnote
+    The generous use of descriptive variables as we try to illustrate in the

+Note that diagrams such as those constructed here will each be significantly

+
+Although \METAPOST\ is a 2D drawing language, it can be easily extended to work
+in 3D. Several attempts have been made in the past ranging from simple to
+complicated. Here, we will take a simple approach.
+
+The \METAPOST\ language includes a triplet variable type, used to handle \type
+{rgb} colors (it also has a quadruplet type used for \type {cmyk} colors). We
+will use this \type {triplet} type to hold 3D coordinates. There is a separate
+\CONTEXT\ module, entitled \type {three}, which creates a new \METAPOST\ instance
+(also named \type {three}), which loads a set of macros that can be used to
+manipulate these triplet coordinates.

+
+For our purposes here, only one function is really necessary: \type
+{projection()} that maps a 3D coordinate to a 2D projection on the page. This
+will not be a perspective projection having a viewpoint and a focus point, but
+rather a very simple oblique projection, useful for, e.g., pseudo|-|3D schematic
+drawings. The \type {Z} coordinate is taken to be \type {up} and the \type {Y}
+coordinate taken to be \type {right}, both in the page of the paper. The third
+coordinate \type {X} is an oblique projection in a right|-|hand coordinate
+system.

+\startsubject [title=Conclusions]
+
+There was initial consensus at the 2017 \CONTEXT\ Meeting in Maibach, Germany,
+where a version of this package was presented, that there was little use of
+developing a purely \CONTEXT\ interface. Rather, the \METAPOST\ package should be
+sufficiently accessible. Since then, however, we decided that the development of
+a derivative \CONTEXT\ interface implementing some basic functionality could
+indeed be useful for many users, although it will necessarily remain somewhat
+limited. Users are recommended to turn to the pure \METAPOST\ interface when more
+sophisticated functionality is needed.
+
+\stopsubject
+
+\startsubject [title=Acknowledgements]
+
+This module was inspired by a request made by Idris Samawi Hamid to draw a
+natural transformation diagram (\in{Figure} [fig:natural]). The \METAPOST\ macros
+that were developed then benefited from improvements suggested by Hans Hagen as
+well as inspiration provided by Taco Hoekwater.
+
+The cover artwork one can recognize as coming under the hand of Hans Hagen that
+he produced when I mentioned that I wanted to do something along these lines. It
+fits very well into the style of manual covers that we distribute with \CONTEXT.
+This manual therefore has been co|-|written by Hans and Alan.

+\startchapter[title=Introduction]
+
+You can do a lot in \CONTEXT\ but for sure there are limitations too. There are
+quite some sub|-|mechanisms and sometimes there are more solutions for one
+problem. For instance, we have several table mechanisms and several
+multi|-|column mechanisms. In this document we will collect information about
+what doesn't work (well) and if possible indicate why. Feel free to submit more
+items. We will also discuss features that do work in most cases but are somewhat
+unreliable.
+
+Does that mean that we cannot make everything work? No, sometimes demands are too
+conflicting. Yes, we can implement more, but it simply doesn't pay off to spend
+time on writing code that is used seldom. Keep in mind that much of \CONTEXT\ is
+written in spare time without any compensation. Publishers have demands but
+seldom are willing to pay for it. Users have demands and no means to pay for it.
+On the other hand, user demands often have challenging properties that trigger
+development. Sometimes a project has as side effect that some mechanism become
+better.
+
+The good news that one can often work around it. Not all typesetting has to be
+fully automatic. And there are always reasonable typographic alternatives. The
+examples shown here can be run on your machine.

+\startchapter[title=Columns and notes]
+
+Because \TEX\ doesn't really support columns we need to cook up some magic to
+achieve them. Especially a mix between single and multi|-|columns is sort of
+tricky. Because notes are inserts and inserts play a role in determining the
+optimal breakpoints they can interfere badly, depending on the mechanism used. In
+\CONTEXT\ we use mixed columns for multi|-|column itemizations and as these can
+have footnotes you can end up in troubles.
+
+\typefile{notnow-columns-and-notes.tex}
+
+In such case the notes are postponed and flushed {\em after} the itemized list so
+they can end up on a next page. If this happens depends on how much room there is
+on the page. Solutions are possible (and the old \MKII\ column handler might
+behave better in some cases) but it's not worth the trouble to complicate the
+already complex code more than needed. Also, it will never be perfect anyway.

+
+Support for side floats is non|-|trivial and no solution will serve all intended
+usage. Over the years we have improved on border cases but it is still not
+perfect. For that reason the implementation is (apart from solving bugs, mostly) frozen.
+Here is an example of a use case that we ran into. We manipulate the spacing with
+an offset parameter.
+
+\typefile{notnow-sidefloats.tex}
+
+You can best play with these parameters and see what they do. If you use this
+mechanism in a long term project, use a frozen instance of \CONTEXT !

+\startchapter[title=The first decade]
+
+When writing this it's hard to believe that we're already a decade working on
+\LUATEX\ and about the same time on \MKIV. The question is, did we achieve the
+objectives? The answer can easily be \quotation {yes} because we didn't start
+with objectives, just with some experiments with a \LUA\ extension interface.
+However, it quickly became clear that this was the way to go. Already in an early
+stage we took a stand in what direction we had to move.
+
+How did we end up with \LUA\ and not one of the other popular scripting
+languages? The \CONTEXT\ macro package always came with a runner. Not only did
+the runner manage the (often) multiple runs, it also took care of sorting the
+index and other inter|-|job activities. Additional helpers were written for
+installing fonts, managing (and converting) images, job control, etc. First they
+were binaries (written in \MODULA\ 2), but successive implementations used \PERL\
+and \RUBY. When I found out that the \SCITE\ editor I switched to had an
+extension mechanism using \LUA, I immediately liked that language. It's clean,
+not bloated, relatively stable, evolves in an academic environment and is not
+driven by commerce and|/|or short term success, and above all, the syntax makes
+the code look good. So, it was the most natural candidate for extending \TEX.
+
+Already for along time, \TEX\ is a stable program and whatever we do with it, we
+should not break it. There has been frontend extensions, like \ETEX, and backend
+extensions, like \PDFTEX, and experiments like \OMEGA\ and \ALEPH\ and we could
+start from there. So, basically we took \PDFTEX, after all, that was what we used
+for the first experiments, and merged some \ALEPH\ directional code in it. A
+tremendous effort was undertaken (thanks to funding by the Oriental \TEX\
+project) to convert the code base from \PASCAL\ to~\CCODE.
+
+It is hard to get an agreement over what needs to be added and it's a real waste
+of time to enter that route by endless discussions: every \TEX\ user has
+different demands and macro packages differ in philosophy . So, in the spirit of
+the extension language \LUA\ we stuck to concept of \quotation {If you want it
+better, write it in \LUA}. As a consequence we had to provide access to the
+internals with efficient and convenient methods, something that happened
+stepwise. We did extend the engine with a few features that make live easier but
+tried to limit ourselves. On the other hand, due to developments with fonts and
+languages we generalized these concepts so that extending and controlling them is
+easier. And, due to developments in math font technology we also added
+alternative code paths to the math renderer.
+
+All these matters have been presented and discussed at meetings, in user group
+journals and in documents that are part of the \CONTEXT\ suite. And during this
+decade the \CONTEXT\ users have been patient testers of whatever we threw at them
+in the \MKIV\ version of this macro package.
+
+It's kind of interesting to note that in the \TEX\ community it takes a while
+before version 1 of programs becomes available. Some programs never (seem to)
+reach that state. However, for us version 1.0 marks the moment that we consider
+the interfaces to be stable. Of course we move on so a version 2.0 can divert and
+provide more or even less interfaces, provide new functionality or drop obsolete
+features. The intermediate versions (up to version one) were always quite useable
+in production. In 2005 the first prototype of \LUATEX\ was demonstrated at the
+\TUG\ conference, and in 2007 at the \TUG\ conference we had a whole day on
+\LUATEX. At that time \CONTEXT\ \MKIV\ evolved fast and we already had decent
+\OPENTYPE\ support as part of the oriental \TEX\ project. It was in those years
+that the major reorganization of the code base took place but in successive years
+many subsystems were opened and cleaned up. There were some occasions where an
+interface was changed for the better but adapting was not that hard. It might
+have helped that much of \CONTEXT\ \MKIV\ is written in \LUA. What also helped is
+that most \CONTEXT\ users quickly switched to \MKIV, if only because \MKII\ was
+frozen. And, thanks to those users, we were able to root out bugs and
+bottlenecks. It was interesting to see that the approach of mixing \TEX,
+\METAPOST\ and \LUA\ catched on quite well.
+
+By the end of September 2016, at the 10\high{th} \CONTEXT\ meeting we released
+what we call the first long term stable version of \LUATEX. This version performs
+quite well but we might still add a few things here and there and the code will be
+further cleaned up and documented. In the meantime \LUATEX\ is also used in other
+macro packages. It will not replace \PDFTEX\ (at least not soon) because that
+engine does the job for most of the publications done in \TEX: articles. As they
+are mostly in English and use traditional fonts, there is no need to switch to
+the more flexible but somewhat slower \LUATEX. In a similar fashion \XETEX\
+serves those who want the benefits of \PDFTEX, hard|-|coded font support and
+token juggling at the \TEX\ level. We will support those engines with \MKII\ but
+as mentioned, we will not develop new code for. We strongly advice \CONTEXT\ users
+to use \LUATEX\ but there the advertisements stop. Personally I haven't used
+\PDFTEX\ (which made \TEX\ survive in the evolving world of electronic documents)
+for a decade and I never really used \XETEX\ (which opened up the \TEX\ world to
+modern fonts). At least for the coming decade I hope that \LUATEX\ can serve us well.

+% This introduction is similar to the workflows chapter.
+
+Some users like the synctex feature that is built in the \TEX\ engines.
+Personally I never use it because it doesn't work well with the kind of documents
+I maintain. If you have one document source, and don't shuffle around (reuse)
+text too much it probably works out okay but that is not our practice. Here I
+will describe how you can enable a more \CONTEXT\ specific synctex support so
+that aware \PDF\ viewers can bring you back to the source.
+

+
+\startsection[title={The premise}]
+
+Most of the time we provide our customers with an authoring workflow consisting
+of:
+
+\startitemize[packed]
+    \startitem the typesetting engine \CONTEXT \stopitem
+    \startitem the styles to generate the desired \PDF\ files \stopitem
+    \startitem the text editor \SCITE \stopitem
+    \startitem the \SUMATRAPDF\ viewer \stopitem
+\stopitemize
+
+For the \MATHML\ we advice the \MATHTYPE\ editor and we provide them with a
+customized \MATHML\ translator for the copy & paste actions. When \ASCIIMATH\ is
+used to code math no special tools are needed.
+
+What people operate this workflow? Sometimes it's an author, but most of the time
+they are editors with a background in copy|-|editing. We call them \XML\ editors,
+because they are maintaining the large (sets of) \XML\ documents and edit
+directly in the \XML\ sources.
+
+Maybe you'll ask yourself \quotation {Can they do that? Can they edit directly in
+the \XML\ resource?} The answer is yes, because after they have hit the
+processing key they are rewarded with a publishable \PDF\ document in a demanding
+layout.
+
+The \XML\ sources have a dual purpose. They form the basis for:

+\startitemize[packed]
+    \startitem
+        all folio products that are generated in \XML\ to \PDF\ workflow(s)
+    \stopitem
+    \startitem
+        the digital web product(s)
+    \stopitem
+\stopitemize
+
+The \XML\ editors do their proofing chapter|-|wise. Sometimes a chapter is one
+big \XML\ file (10.000 lines is no exception when the chapter contains hundreds
+of bloated \MATHML\ snippets). In other projects they have to deal with chapters
+that are made up of hundreds (100 upto 500) of smaller \XML\ files.
+
+\stopsection
+
+\startsection[title={The problem}]
+
+Let's keep it simple: there's a typo. Here's what an \XML\ editor will do:
+
+\startitemize[packed]
+    \startitem
+        start \SCITE
+    \stopitem
+    \startitem
+        open a file
+    \stopitem
+    \startitem
+        correct the typo
+    \stopitem
+    \startitem
+        generate the \PDF
+    \stopitem
+    \startitem
+        proof the \PDF\ and see if his alteration has some undesired side
+        effects like text flow of image floating
+    \stopitem
+\stopitemize
+
+So far so good. When the editor dealing with one big \XML\ file there's no
+problem. Hopefully the filename will indicate the specific chapter. He or she
+opens the file and searches for the typo. And then correction happens. But what
+if there are hundreds of small \XML\ files. How does the editor know in which
+file the typo can be found?
+
+First, let's give a few statistics based on two projects that are in a revision
+stage.
+

+The \XML\ resource passes three stages: a raw, a semi final and a final version.

+\HL
+\stoptabulate
+
+Keep in mind that altering text may cause text to flow and images to float in a
+way that an \XML\ editor will have to finetune and needs multiple runs for one
+correction.
+
+Just to give an idea of the work involved. A typical semi final needs some 50
+runs where each run takes 20 seconds (assuming 3 runs to get all cross
+referencing right). The numbers of explicit pagebreaks is about 5, and (related
+to formulas) explicit linebreaks around 8. It takes some 2 hours to get
+everything right, which includes checking in detail, fixing some things and if
+needed moving content a bit around.
+
+Now we broaden the earlier question into: how can we make the work of an \XML\
+editor as easy and efficient as possible?
+
+\stopsection
+
+\startsection[title={Enhancing efficiency}]
+
+Since it is easier to proof content for folio and web via PDF documents we
+generate proof \PDF\ files in which the complete content is shown. The proof can
+be a massive document. A normal 40 page chapter can explode to 140 pages
+visualizing all the content that is coded in the \XML\ file(s).
+
+The content in the proof is shown in an effective way and a functional order.
+Let's give a few examples of how we enhance the \XML\ editors effectiveness:
+
+\startitemize[packed]
+
+\startitem
+    By default the proof \PDF\ file is interactive which serves testing the tocs
+    and the register.
+\stopitem
+\startitem
+    The web hyperlinks are active so their destinatation can be tested.
+\stopitem
+\startitem
+    The questions and their answers are displayed in eachothers proximity. This
+    sounds logical but in folio they are two seperate products (theory and
+    answer books).
+\stopitem
+\startitem
+    Medium specific content (web or folio) is typographically highligthed. For
+    example by colored backgrounds.
+\stopitem
+\startitem
+    When spelling mode is on the \XML\ editor can easily pick out the colored
+    misspelled words.
+\stopitem
+\startitem
+    Images can be active areas although this is of no interest to \XML\ editors.
+    Clicking the image results in opening the image file in its corresponding
+    application for maintenance.
+\stopitem
+\startitem
+    For practical reasons the filenames and paths of the \XML\ files are
+    displayed. The filenames are active links and clicking them results in
+    opening the destination \XML\ file in \SCITE.
+\stopitem
+\stopitemize
+
+Okay. The last option is a nice feature. However, the destination file is opened
+at the top of the file and you still have to find the typo or whatever
+incorrect issue you are looking for.
+
+So a further enhancement in efficiency would be to jump to the typo's
+corresponding line in the \XML\ source. This is where \SYNCTEX\ comes into view.
+This feature, present in the \TEX\ engines, provides a way to go from \PDF\ to
+source by using a secondary file with positions. Unfortunately that mechanism is
+hardly useable for \CONTEXT\ because it assumes a page and file handling model
+different from what we use. However, as \CONTEXT\ uses \LUATEX, it can also
+provide it's own alternative.
+
+\stopsection
+
+% The rest is similar to the workflows chapter.
+
+\startsection[title=What we want]
+
+The \SYNCTEX\ method roughly works as follows. Internally \TEX\ constricts linked
+lists of glyphs, kerns, glue, boxes, rules etc. These elements are called nodes.
+Some nodes carry information about the file and line where they were created. In
+the backend this information gets somehow translated in a (sort of) verbose tree
+that describes the makeup in terms of boxes, glue and kerns. From that
+information the \SYNCTEX\ parser library, hooked into a \PDF\ viewer, can go back
+from a position on the screen to a line in a file. One would expect this to be a
+relative simple rectangle based model, but as far as I can see it's way more
+complex than that. There are some comments that \CONTEXT\ is not supported well
+because it has a layered page model, which indicates that there are some
+assumptions about how macro packages are supposed to work. Also the used
+heuristics not only involve some specific spot (location) but also involve the
+corners and edges. It is therefore not so much a (simple) generic system but a
+mechanism geared for a macro package like \LATEX.
+
+Because we have a couple of users who need to edit complex sets of documents,
+coded in \TEX\ or \XML, I decided to come up with a variant that doesn't use the
+\SYNCTEX\ machinery but manipulates the few \SYNCTEX\ fields directly \footnote {This
+is something that in my opinion should have been possible right from the start
+but it's too late now to change the system and it would not be used beyond
+\CONTEXT\ anyway.} and eventually outputs a straightforward file for the editor.
+Of course we need to follow some rules so that the editor can deal with it. It
+took a bit of trial and error to get the right information in the support file
+needed by the viewer but we got there.
+
+The prerequisites of a decent \CONTEXT\ \quotation {click on preview and goto
+editor} are the following:
+
+\startitemize
+
+\startitem
+    It only makes sense to click on text in the text flow. Headers and footers
+    are often generated from structure, and special typographic elements can
+    originate in macros hooked into commands instead of in the source.
+\stopitem
+
+\startitem
+    Users should not be able to reach environments (styles) and other files
+    loaded from the (normally read|-|only) \TEX\ tree, like modules. We don't
+    want accidental changes in such files.
+\stopitem
+
+\startitem
+    We not only have \TEX\ files but also \XML\ files and these can normally
+    flush in rather arbitrary ways. Although the concept of lines is sort of
+    lost in such a file, there is still a relation between lines and the snippets
+    that make out the content of an \XML\ node.
+\stopitem
+
+\startitem
+    In the case of \XML\ files the overhead related to preserving line
+    numbers should be minimal and have no impact on loading and memory when
+    these features are not used.
+\stopitem
+
+\startitem
+    The overhead in terms of an auxiliary file size and complexity as well
+    as producing that file should be minimal. It should be easy to turn on and
+    off these features. (I'd never turn them on by default.)
+\stopitem
+
+\stopitemize
+
+It is unavoidable that we get more run time but I assume that for the average user
+that is no big deal. It pays off when you have a workflow when a book (or even a
+chapter in a book) is generated from hundreds of small \XML\ files. There is no
+overhead when \SYNCTEX\ is not used.
+
+In \CONTEXT\ we don't use the built|-|in \SYNCTEX\ features, that is: we let
+filename and line numbers be set but often these are overloaded explicitly. The
+output file is not compressed and constructed by \CONTEXT. There is no benefit in
+compression and the files are probably smaller than default \SYNCTEX\ anyway.
+
+\stopsection
+
+\startsection[title=Commands]
+
+Although you can enable this mechanism with directives it makes sense to do it
+using the following command.
+
+\starttyping
+\setupsynctex[state=start]
+\stoptyping
+
+The advantage of using an explicit command instead of some command line option is
+that in an editor it's easier to disable this trickery. Commenting that line will
+speed up processing when needed. This command can also be given in an environment
+(style). On the command line you can say
+
+\starttyping
+context --synctex somefile.tex
+\stoptyping
+
+A third method is to put this at the top of your file:
+
+\starttyping
+% synctex=yes
+\stoptyping
+
+Often an \XML\ files is very structured and although probably the main body of
+text is flushed as a stream, specific elements can be flushed out of order. In
+educational documents flushing for instance answers to exercises can happen out of
+order. In that case we still need to make sure that we go to the right spot in
+the file. It will never be 100\% perfect but it's better than nothing. The
+above command will also enable \XML\ support.
+
+If you don't want a file to be accessed, you can block it:
+
+\starttyping
+\blocksynctexfile[foo.tex]
+\stoptyping
+
+Of course you need to configure the viewer to respond to the request for
+editing. In Sumatra combined with SciTE the magic command is:
+
+\starttyping
+c:\data\system\scite\wscite\scite.exe "%f" "-goto:%l"
+\stoptyping
+
+Such a command is independent of the macro package so you can just consult the
+manual or help info that comes with a viewer, given that it supports this linking
+back to the source at all.
+
+If you enable tracing (see next section) you can what has become clickable.
+Instead of words you can also work with ranges, which not only gives less runtime
+but also much smaller \type {.synctex} files. Use
+
+\starttyping
+\setupsynctex[state=start,method=min]
+\stoptyping
+
+to get words clickable and
+
+\starttyping
+\setupsynctex[state=start,method=max]
+\stoptyping
+
+if you want somewhat more efficient ranges. The overhead for \type {min} is about
+10 percent while \type {max} slows down around 5 percent.
+
+\stopsection
+
+\startsection[title=Tracing]
+
+In case you want to see what gets synced you can enable a tracker:
+
+\starttyping
+\enabletrackers[system.synctex.visualize]
+\enabletrackers[system.synctex.visualize=real]
+\stoptyping
+
+The following tracker outputs some status information about \XML\ flushing. Such
+trackers only make sense for developers.
+
+\starttyping
+\enabletrackers[system.synctex.xml]
+\stoptyping
+
+\stopsection
+
+\startsection[title=Warning]
+
+Don't turn on this feature when you don't need it. This is one of those mechanism
+that hits performance badly.
+
+Depending on needs the functionality can be improved and|/|or extended. Of course
+you can always use the traditional \SYNCTEX\ method but don't expect it to behave
+as described here.

+\startchapter[title=Emoji again]
+
+Because at the \CONTEXT\ 2016 meeting color fonts \footnote {For that occasion
+the cowfont, a practical joke concerning Dutch \quote {koeieletters}, were turned
+into a color font and presented at the meeting.} were on the agenda, some time
+was spent on emoji (these colorful small picture glyphs). When possible I bring
+kids to the Bacho\TEX\ conference so for the 2017 BachoTUG I decided to do
+something with emoji that, after all, are mostly used by those younger than I am.
+So, I had to take a look at the current state. Here are some observations.
+
+The \UNICODE\ standard defines a whole lot of emoji and if mankind manages to
+survive for a while one can assume that a lot more will be added. After all,
+icons as well as variants keep evolving. There are several ways to organize these
+symbols in groups but I will not give grouping a try. Just visit \type
+{emojipedia.org} and you get served well. For this story I only mention that:
+
+\startitemize
+    \startitem
+        There are quite some shapes and nearly all of them are in color. The
+        yellow ones, smilies and such, are quite prominently present but there
+        are many more.
+    \stopitem
+    \startitem
+        A special subset is fulled by persons: man, woman, girl, boy and recently
+        a baby.
+    \stopitem
+    \startitem
+        The grown ups can be combined in loving couples (either or not kissing)
+        and then can form families, but only upto 2 young kids or gender neutral
+        babies.
+    \stopitem
+    \startitem
+        All persons can be flagged with one of five skin tones so that not all
+        persons (or heads) look bright yellow.
+    \stopitem
+    \startitem
+        Interesting is that girls and boys are still fond of magenta (pinkish)
+        and cyan (blueish) cloths and ornaments. Also haircuts are rather
+        specific to the gender.
+    \stopitem
+\stopitemize
+
+For rendering color emojis we have a few color related \OPENTYPE\ font properties
+available: bitmaps, \SVG\, and stacked glyphs. Now, if you think of the
+combinations that can be made with skin tones, you realize that fonts can become
+pretty large if each combination results in a glyph. In the first half of 2017
+\MICROSOFT\ released an update for its emoji font and the company took the
+challenge to provide not only mixed skin tone couples, but also supported skin
+tones for the kids, including a baby.
+
+This recent addition already adds over 25.000 additional glyphs \footnote {That
+is the amount I counted when I added all combinations runtime but the emojipedia
+mentions twice that amount. Currently in \CONTEXT\ we resolve such combinations
+when requested.} so imagine what will happen in the future. But, instead of
+making a picture for each variant, a different solution has been chosen. For
+coloring this seguiemj font uses the (very flexible) stacking technology: a color
+shape is an overlay of colored symbols. The colors are organized in pallets and
+it's no big deal to add additional pallets if needed. Instead of adding
+pre|-|composed shapes (as is needed with bitmaps and \SVG) snippets are used to
+build alternative glyphs and these can be combined into new shapes by
+substitution and positioning (for that kerns, mark anchoring and distance
+compensation is used).
+
+So, a family can be constructed of composed shapes (man, woman, etc) that each
+are composed of snippets (skull, hair, mouth, eyes). So, effectively a family of
+four is a bunch of maybe 25 small glyphs overlayed and colored. In \in {figure}
+[fig:emojisnippets] we see how a shape is constructed out of separate glyphs. \in
+{Figure} [fig:emojisnippetsoverlay] shows how they can be overlayed with colors
+(we use a dedicated color set).

+When a font supports it, a sequence of emoji can be turned into a more compact

+applied in such combinations. \in {Figure} [fig:emojiglyphs] shows the small
+snippets.

+
+When we have to choose a font we need to take the following criteria into
+account:
+
+\startitemize
+\startitem
+    What is the quality of the shapes? For sure, outlines are best if you want to
+    scale too.
+\stopitem
+\startitem
+    How efficient is a shape constructed. In that respect a bitmap or \SVG\ image
+    is just one entity.
+\stopitem
+\startitem
+    How well can (semi) arbitrary combinations of emoji be provided. Here the
+    glyph approach wins.
+\stopitem
+\startitem
+    Are all skin colors for all human relates shapes supported? Actually it opens
+    the possibility for racist fonts.
+\stopitem
+\startitem
+    Are all reasonable combinations of persons supported? It looks like (depending
+    on time and version) kissing men or women can be missing, maybe because of
+    social political reasons.
+\stopitem
+\startitem
+    Are black and white shapes provided alongside color shapes.
+\stopitem
+\stopitemize
+
+Maybe an \SVG\ or bitmap image can have a lot of detail compared to a stacked
+glyph but, when we're just using pictographic representations, the later is the
+best choice.
+
+When I was playing a bit with the skin tone variants and other combinations that
+should result in some composed shape, I used the \UNICODE\ test files but I got
+the impression that there are some errors in the test suite, for instance with
+respect to modifiers. Maybe the fonts are just doing the wrong thing or maybe
+some implement these sequences a bit inconsistent. This will probably improve
+over time but the question is if we should intercept issues. I'm not in favour of
+this because it adds more and more fuzzy code that not only wastes cycles
+(energy) but is also a conceptual horror. So, when testing, imperfection has to
+be accepted for now. This is no big deal as until now no one ever asked for emoji
+support in \CONTEXT.
+
+When no combined shape is provided, the original sequence shows up. A side effect
+can be that zero|-|width|-| joiners and modifiers become visible. This depends on
+the fonts. Users probably don't care that much about it. Now how do we suppose
+that users enter these emoji (sequences) in a document source? One can imagine a
+pop up in the editor but \TEX ies are often using commands for special cases.
+
+We already showed some combined shapes. The reader might appreciate the outcome
+but getting there from the input takes a bit of work. For instance a two person
+\typ {man light skin tone woman medium skin tone girl medium-light skin tone baby
+medium-light skin tone} involves this:
+
+\blank
+\start
+    \setupalign[verytolerant]
+    \showotfcomposition
+      {seguiemj*seguiemj-cl}
+      {1}
+      {\resolvedemoji{family
+            man light skin tone
+            woman medium skin tone
+            girl medium-light skin tone
+            baby medium-light skin tone}}
+\stop
+\blank
+
+A black and white example is the following \type {family woman girl}:
+
+\blank
+\start
+    \setupalign[verytolerant]
+    \showotfcomposition
+      {seguiemj*seguiemj-bw}
+      {1}
+      {\resolvedemoji{family woman girl}}
+\stop
+\blank
+
+I will not show all emoji, just the subset that contains the word \type {woman}
+in the description. As you can see the persons in the sequences are separated by
+a zero|-|width|-|joiner. There are some curious ones, for instance a \typ {woman
+wearing turban} which in terms of \UNICODE\ input is a female combine with a
+turban wearing man becomes a beardless woman wearing a turban. Woman vampires and
+zombies are not supported so these are male properties.

+In \in {figure} [fig:emojioverload] we see how this is applied. You can provide
+as many colors as needed but when you don't provide enough the last one is used.
+This way we get the overlayed transparent colors in the examples. By using
+transparency we don't obscure shapes.
+
+The emojipedia mentions \quotation {Asked about the design, \MICROSOFT\ told
+emojipedia that one of the reasons for the thick stroke was to allow each emoji

+do the trick, so just make sure that it doesn't become white. And, before I read
+that remark, while preparing a presentation with a colored background, I had
+already noticed that using a background was no problem. This font definitely sets
+the standard.
+
+How do we know what colors are used? The next table shows the first color palette
+of seguiemj. There are quite some colors so defining your own definitely involved
+some studying.

+
+Normally special symbols are accessed in \CONTEXT\ with the \type {symbol}
+command where symbols are organized in symbol sets. This is a rather old
+mechanism and dates from the time that fonts were limited in coverage and symbols
+were collected in special fonts. The emoji are accessed by their own command:
+\type {\emoji}. The font used has the font synonym \type {emoji} so you need to
+set that one first:
+
+\starttyping
+\definefontsynonym[emoji][seguiemj*seguiemj-cl]

+\startbuffer
+\emoji{woman light skin tone}\quad
+\emoji{woman scientist}\quad
+{\bfd bigger \emoji{man health worker}}
+\stopbuffer
+
+\typebuffer
+
+or typeset: \getbuffer
+
+The emoji symbol scales with the normal running font. When you ask for a family
+with skin toned members the lookup can result in another match (or no match)
+because one never knows to what extend a font supports it.

+\startchapter[title={Plug mode, an application of ffi}]
+
+A while ago, at an NTG meeting, Kai Eigner and Ivo Geradts demonstrated how to
+use the Harfbuzz (hb) library for processing \OPENTYPE\ fonts. The main
+motivation for them playing with that was that it provides a way to compare the
+\LUA\ based font machinery with other methods. They also assumed that it would
+give a better performance for complex fonts and|/|or scripts.
+
+One of the guiding principles of \LUATEX\ development is that we don't provide
+hard coded solutions. For that reason we opened up the internals so that one can
+provide solutions written in pure \LUA, but, of course, one can cooperate with
+libraries via \LUA\ code as well. Hard coding solutions makes no sense as there
+are often several solutions possible, depending on one's need. Although
+development is closely related to \CONTEXT, the development of the \LUATEX\
+engine is generic. We try to be macro package agnostic. Already in an early stage
+we made sure that the \CONTEXT\ font handler could be used in other packages as
+well, but one can easily dream up light weight variants for specific purposes.
+The standard \TEX\ font handling was kept and is called \type {base} mode in
+\CONTEXT. The \LUA\ variant is tagged \type {node} mode because it operates on
+the node list. Later we will refer to these modes.
+
+With the output of \XETEX\ for comparison, the first motive mentioned for looking
+into support for such a library is not that strong. And when we want to test
+against the standard, we can use MS-Word. A minimal \CONTEXT\ \MKIV\ installation
+one only has the \LUATEX\ engine. Maintaining several renderers simultaneously
+might give rise to unwanted dependencies.
+
+The second motive could be more valid for users because, for complex fonts, there
+is|=|or at least was|=|a performance hit with the \LUA\ variant. Some fonts use
+many lookup steps or are inefficient even in using their own features. It must be
+said that till now I haven't heard \CONTEXT\ users complain about speed. In fact,
+the font handling became many times faster the last few years, and probably no
+one even noticed. Also, when using alternatives to the built in methods, in the
+end, you will loose functionality and|/|or interactions with other mechanisms
+that are built into the current font system. Any possible gain in speed is lost,
+or even becomes negative, when a user wants to use additional functionality that
+requires additional processing. \footnote {In general we try to stay away from
+libraries. For instance, graphics can be manipulated with external programs, and
+caching the result is much more efficient than recreating it. Apart from \SQL\
+support, where integration makes sense, I never felt the need for libraries. And
+even \SQL\ can efficiently be dealt with via intermediate files.}
+
+Just kicking in some alternative machinery is not the whole story. We still need
+to deal with the way \TEX\ sees text, and that, in practice, is as a sequence of
+glyph nodes|=|mixed with discretionaries for languages that hyphenate, glue,
+kern, boxes, math, and more. It's the discretionary part that makes it a bit
+complex. In contextual analysis as well as positioning one needs to process up to
+three additional cases: the pre, post and replace texts|=|either or not linked
+backward and forward. And as applied features accumulate one ends up winding and
+unwinding these snippets. In the process one also needs to keep an eye on spaces
+as they can be involved in lookups. Also, when injecting or removing glyphs one
+needs to deal with attributes associated with nodes. Of course something hard
+codes in the engine might help a little, but then one ends up with the situation
+where macro packages have different demands (and possible interactions) and no
+solution is the right one. Using \LUA\ as glue is a way to avoid that problem. In
+fact, once we go along that route, it starts making sense to come up with a
+stripped down \LUATEX\ that might suit \CONTEXT\ better, but it's not a route we
+are eager to follow right now.
+
+Kai and Ivo are plain \TEX\ users so they use a font definition and switching
+environment that is quite different from \CONTEXT. In an average \CONTEXT\ run
+the time spent on font processing is measurable but not the main bottleneck
+because other time consuming things happen. Sometimes the load on the font
+subsystem can be higher because we provide additional features normally not found
+in \OPENTYPE. Add to that a more dynamic font model and it will be clear that
+comparing performance between situations that use different macro packages is not
+that trivial (or relevant).
+
+More reasons why we follow a \LUA\ route are that we: support (run time
+generated) virtual fonts, are able to kick in additional features, can let the
+font mechanism cooperate with other functionality, and so on. In the upcoming
+years more trickery will be provided in the current mechanisms. Because we had to
+figure out a lot of these \OPENTYPE\ things a decade ago when standards were
+fuzzy quite some tracing and visualization is available. Below we will see some
+timings, It's important to keep in mind that in \CONTEXT\ the \OPENTYPE\ font
+handler can do a bit more if requested to do so, which comes with a bit of
+overhead when the handler is used in \CONTEXT|=|something we can live with.
+
+Some time after Kai's presentation he produced an article, and that was the
+moment I looked into the code and tried to replicate his experiments. Because
+we're talking libraries, one can understand that this is not entirely trivial,
+especially because I'm on another platform than he is|=|Windows instead of OSX.
+The first thing that I did was rewrite the code that glues the library to \TEX\
+in a way that is more suitable for \CONTEXT. Mixing with existing modes (\type
+{base} or \type {node} mode) makes no sense and is asking for unwanted
+interferences, so instead a new \type {plug} mode was introduced. A sort of
+general text filtering mechanism was derived from the original code so that we
+can plug in whatever we want. After all, stability is not the strongest point of
+today's software development, so when we depend on a library, we need to be
+prepared for other (library based) solutions|=|for instance, if I understood
+correctly, \XETEX\ switched a few times.
+
+After redoing the code the next step was to get the library running and I decided
+that the \type {ffi} route made most sense. \footnote {One can think of a
+intermediate layer but I'm pretty sure that I have different demands than others,
+but \type {ffi} sort of frees us from endless discussions.} Due to some expected
+functions not being supported, my efforts in using the library failed. At that
+time I thought it was a matter of interfacing, but I could get around it by
+piping into the command line tools that come with the library, and that was good
+enough for testing. Of course it was dead slow, but the main objective was
+comparison of rendering so it doesn't matter that much. After that I just quit
+and moved on to something else.
+
+At some point Kai's article came close to publishing, and I tried the old code
+again, and, surprise, after some messing around, the library worked. On my system
+the one shipped with Inkscape is used, which is okay as it frees me from bothering
+about installations. As already mentioned, we have no real reason in \CONTEXT\
+for using fonts libraries, but the interesting part was that it permitted me to
+play with this so called \type {ffi}. At that moment it was only available in
+\LUAJITTEX\. Because that creates a nasty dependency, after a while, Luigi
+Scarso and I managed to get a similar library working in stock \LUATEX\, which is
+of course the reference. So, I decided to give it a second try, and in the process
+I rewrote the interfacing code. After all, there is no reason not to be nice for
+libraries and optimize the interface where possible.
+
+Now, after a decade of writing \LUA\ code, I dare to claim that I know a bit
+about how to write relatively fast code. I was surprised to see that where Kai
+claimed that the library was faster than the \LUA\ code.I saw that it really
+depends on the font. Sometimes the library approach is actually slower, which is
+not what one expects. But remember that one argument for using a library is for
+complex fonts and scripts. So what is meant with complex?
+
+Most Latin fonts are not complex|=|ligatures and kerns and maybe a little bit of
+contextual analysis. Here the \LUA\ variant is the clear winner. It runs upto ten
+times faster. For more complex Latin fonts, like EBgaramond, that resolves
+ligatures in a different way, the library catches up, but still the \LUA\ handler
+is faster. Keep in mind that we need to juggle discretionary nodes in any case.
+One difference between both methods is that the \LUA\ handler runs over all the
+lists (although it has to jump over fonts not being processed then), while the
+library gets snippets. However, tests show that the overhead involved in that is
+close to zero and can be neglected. Already long ago we saw that when we compared
+\MKIV\ \LUATEX\ and \MKII\ \XETEX, the \LUA\ based font handler is not that slow
+at all. This makes sense because the problem doesn't change, and maybe more
+importantly because \LUA\ is a pretty fast language. If one or the other approach
+is less that two times faster the gain will probably go unnoticed in real runs.
+In my experience a few bad choices in macro or style writing is more harmful than
+a bit slower font machinery. Kick in some additional node processing and it might
+make comparison of a run even harder. By the way, one reason why font handling
+has been sped up over the years is because our workflows sometimes have a high
+load, and, for instance, processing a set of 5 documents remotely has to be fast.
+Also, in an edit workflow you want the runtime to be a bit comfortable.
+
+Contrary to Latin, a pure Arabic text (normally) has no discretionary nodes, and
+the library profits most of this. Some day I have to pick up the thread with
+Idris about the potential use of discretionary nodes in Arabic typesetting.
+Contrary to Arabic, Latin text has not many replacements and positioning, and,
+therefore, the \LUA\ variant gets the advantage. Some of the additional features
+that the \LUA\ variant provides can, of course, be provided for the library
+variant by adding some pre- and postprocessing of the list, but then you quickly
+loose any gain a library provides. So, Arabic has less complex node lists with no
+branches into discretinaries, but it definitely has more replacements,
+positioning and contextual lookups due to the many calls to helpers in the \LUA\
+code. Here the library should win because it can (I assume) use more optimized
+datastructures.
+
+In Kai's prototype there are some cheats for right|-|to|-|left rendering and
+special scripts like Devanagari. As these tweaks mostly involve discretionary
+nodes; there is no real need for them. When we don't hyphenate no time is wasted
+anyway. I didn't test Devanagari, but there is some preprocessing needed in the
+\LUA\ variant (provided by Kai and Ivo) that I might rewrite from scratch once I
+understand what happens there. But still, I expect the library to perform
+somewhat better there but I didn't test it. Eventually I might add support for
+some more scripts that demand special treatments, but so far there has not been
+any request for it.
+
+So what is the processing speed of non|-|Latin scripts? An experiment with Arabic
+using the frequently used Arabtype font showed that the library performs faster,
+but when we use a mixed Latin and Arabic document the differences become less
+significant. On pure Latin documents the \LUA\ variant will probably win. On pure
+Arabic the library might be on top. On average there is little difference in
+processing speed between the \LUA\ and library engines when processing mixed
+documents. The main question is, does one want to loose functionality provided by
+the \LUA\ variant? Of course one can depend on functionality provided by the
+library but not by the \LUA\ variant. In the end the user decides.
+
+How did we measure? The baseline measurement is the so called \type {none} mode:
+nothing is done there. It's fast but still takes a bit of time as it is triggered
+by a general mode identifying pass. That pass determines what font processing
+modes are needed for a list. \type {Base} mode only makes sense for Latin and has
+some limitations. It's fast and, basically, its run time can be neglected. That's
+why, for instance, \PDFTEX\ is faster than the other engines, but it doesn't do
+\UNICODE\ well. \type {Node} mode is the fancy name for the \LUA\ font handler.
+So, in order of increasing run time we have: \type {none}, \type {base} and \type
+{node}. If we compare \type{node} mode with \type {plug} mode (in our case using
+the hb library), we can subtract \type {none} mode. This gives a cleaner (more
+distinctive) comparison but not a real honest one because the identifying pass
+always happens.
+
+We also tested with and without hyphenation, but in practice that makes no sense.
+Only verbatim is typeset that way, and normally we typeset that in \type {none}
+mode anyway. On the other hand mixing fonts does happen. All the tests start with
+forced garbage collection in order to get rid of that variance. We also pack into
+horizontal boxes so that the par builder (with all kind of associated callbacks)
+doesn't kick in, although the \type {node} mode should compensate that.
+
+Keep in mind that the tests are somewhat dumb. There is no overhead in handling
+structure, building pages, adding color or whatever. I never process raw text. As
+a reference it's no problem to let \CONTEXT\ process hundreds of pages per
+second. In practice a moderate complex document like the metafun manual does some
+20 pages per second. In other words, only a fraction of the time is spent on
+fonts. The timings for \LUATEX\ are as follows:
+
+\usemodule[m-fonts-plugins]
+
+\startluacode
+    local process = moduledata.plugins.processlist
+    local data    = table.load("m-fonts-plugins-timings-luatex.lua")
+                 or table.load("t:/sources/m-fonts-plugins-timings-luatex.lua")
+
+    context.testpage { 6 }
+    context.subsubject("luatex latin")
+    process(data.timings.latin)
+    context.testpage { 6 }
+    context.subsubject("luatex arabic")
+    process(data.timings.arabic)
+    context.testpage { 6 }
+    context.subsubject("luatex mixed")
+    process(data.timings.mixed)
+\stopluacode
+
+The timings for \LUAJITTEX\ are, of course, overall better. This is because the
+virtual machine is faster, but at the cost of some limitations. We seldom run
+into these limitations, but fonts with large tables can't be cached unless we
+rewrite some code and sacrifice clean solutions. Instead, we perform a runtime
+conversion which is not that noticeable when it's just a few fonts. The numbers
+below are not influenced by this as the test stays away from these rare cases.
+
+\startluacode
+    local process = moduledata.plugins.processlist
+    local data    = table.load("m-fonts-plugins-timings-luajittex.lua")

+
+A few side notes. Since a library is an abstraction, one has to live with what
+one gets. In my case that was a crash in \UTF-32 mode. I could get around it, but
+one advantage of using \LUA\ is that it's hard to crash|=|if only because as a
+scripting language it manages its memory well without user interference. My
+policy with libraries is just to wait till things get fixed and not bother with
+the why and how of the internals.
+
+Although \CONTEXT\ will officially support the \type {plug} model, it will not be
+actively used by me, or in documentation, so for support users are on their own.
+I didn't test the \type {plug} mode in real documents. Most documents that I
+process are Latin (or a mix), and redefining feature sets or adapting styles for
+testing makes no sense. So, can one just switch engines without looking at the
+way a font is defined? The answer is|=|not really, because (even without the user
+knowing about it) virtual fonts might be used, additional features kicked in and
+other mechanisms can make assumptions about how fonts are dealt with too.
+
+The useability of \type {plug} mode probably depends on the workflow one has. We
+use \CONTEXT\ in a few very specific workflows where, interestingly, we only use a
+small subset of its functionality. Most of which is driven by users, and tweaking
+fonts is popular and has resulted in all kind of mechanisms. So, for us it's
+unlikely that we will use it. If you process (in bursts) many documents in
+succession, each demanding a few runs, you don't want to sacrifice speed.
+
+Of course timing can (and likely will) be different for plain \TEX\ and \LATEX\
+usage. It depends on how mechanisms are hooked into the callbacks, what extra
+work is done or not done compared to \CONTEXT. This means that my timings for
+\CONTEXT\ for sure will differ from those of other packages. Timings are a
+snapshot anyway. And as said, font processing is just one of the many things that
+goes on. If you are not using \CONTEXT\ you probably will use Kai's version
+because it is adapted to his use case and well tested.
+
+A fundamental difference between the two approaches is that|=|whereas the \LUA\
+variant operates on node lists only, the \type {plug} variant generates strings
+that get passed to a library where, in the \CONTEXT\ variant of hb support, we
+use \UTF-32 strings. Interesting, a couple of years ago I considered using a
+similar method for \LUA\ but eventually decided against it, first of all for
+performance reasons, but mostly because one still has to use some linked list
+model. I might pick up that idea as a variant, but because all this \TEX\ related
+development doesn't really pay off and costs a lot of free time it will probably
+never happen.
+
+I finish with a few words on how to use the plug model. Because the library
+initializes a default set of features,\footnote {Somehow passing features to the
+library fails for Arabic. So when you don't get the desired result, just try with
+the defaults.} all you need to do is load the plugin mechanism:
+
+\starttyping
+\usemodule[fonts-plugins]
+\stoptyping
+
+Next you define features that use this extension:
+
+\starttyping
+\definefontfeature
+  [hb-native]
+  [mode=plug,
+   features=harfbuzz,
+   shaper=native]
+\stoptyping
+
+After this you can use this feature set when you define fonts. Here is a complete
+example:
+
+\starttyping
+\usemodule[fonts-plugins]
+
+\starttext
+
+    \definefontfeature
+      [hb-library]
+      [mode=plug,
+       features=harfbuzz,
+       shaper=native]
+
+    \definedfont[Serif*hb-library]
+
+    \input ward \par
+
+    \definefontfeature
+      [hb-binary]
+      [mode=plug,
+       features=harfbuzz,
+       method=binary,
+       shaper=uniscribe]
+
+    \definedfont[Serif*hb-binary]
+
+    \input ward \par
+
+\stoptext
+\stoptyping
+
+The second variant uses the \type {hb-shape} binary which is, of course, pretty
+slow, but does the job and is okay for testing.
+
+There are a few trackers available too:
+
+\starttyping
+\enabletrackers[fonts.plugins.hb.colors]
+\enabletrackers[fonts.plugins.hb.details]
+\stoptyping
+
+The first one colors replaced glyphs while the second gives lot of information
+about what is going on. If you want to know what gets passed to the library you
+can use the \type {text} plugin:
+
+\starttyping
+\definefontfeature[test][mode=plug,features=text]
+\start
+    \definedfont[Serif*test]
+    \input ward \par
+\stop
+\stoptyping
+
+This produces something:
+
+\starttyping[style=\ttx]
+otf plugin > text > start run 3
+otf plugin > text > 001 : [-] The [+]-> U+00054 U+00068 U+00065

+otf plugin > text > 009 : [+] an- [-]-> U+00061 U+0006E U+0002D
+\stoptyping
+
+You can see how hyphenation of \type {habi-tat} results in two snippets and a
+whole word. The font engine can decide to turn this word
+into a disc node with a pre, post and replace text. Of course the machinery will
+try to retain as many hyphenation points as possible. Among the tricky parts of
+this are lookups across and inside discretionary nodes resulting in (optional)
+replacements and kerning. You can imagine that there is some trade off between
+performance and quality here. The results are normally acceptable, especially
+because \TEX\ is so clever in breaking paragraphs into lines.
+
+Using this mechanism (there might be variants in the future) permits the user to
+cook up special solutions. After all, that is what \LUATEX\ is about|=|the
+traditional core engine with the ability to plug in your own code using \LUA.
+This is just an example of it.
+
+I'm not sure yet when the plugin mechanism will be in the \CONTEXT\ distribution,
+but it might happen once the \type {ffi} library is supported in \LUATEX. At the
+end of this document the basics of the test setup are shown, just in case you
+wonder what the numbers apply to.
+
+Just to put things in perspective, the current (February 2017) \METAFUN\ manual
+has 424 pages. It takes \LUATEX\ 18.3 seconds and \LUAJITTEX\ 14.4 seconds on my
+Dell 7600 laptop with 3840QM mobile i7 processor. Of this 6.1 (4.5) seconds is
+used for processing 2170 \METAPOST\ graphics. Loading the 15 fonts used takes
+0.25 (0.3) seconds, which includes also loading the outline of some. Font
+handling is part of the, so called, hlist processing and takes around 1 (0.5)
+second, and attribute backend processing takes 0.7 (0.3) seconds. One problem in
+these timings is that font processing often goes too fast for timing, especially
+when we have lots of small snippets. For example, short runs like titles and such
+take no time at all, and verbatim needs no font processing. The difference in
+runtime between \LUATEX\ and \LUAJITTEX\ is significant so we can safely assume
+that we spend some more time on fonts than reported. Even if we add a few
+seconds, in this rather complete document, the time spent on fonts is still not
+that impressive. A five fold increase in processing (we use mostly Pagella and
+Dejavu) is a significant addition to the total run time, especially if you need a
+few runs to get cross referencing etc.\ right.
+
+The test files are the familiar ones present in the distribution. The \type
+{tufte} example is a good torture test for discretionary processing. We preload
+the files so that we don't have the overhead of \type {\input}.
+
+\starttyping
+\edef\tufte{\cldloadfile{tufte.tex}}
+\edef\khatt{\cldloadfile{khatt-ar.tex}}
+\stoptyping
+
+We use six buffers for the tests. The Latin test uses three fonts and also
+has a paragraph with mixed font usage. Loading the fonts happens once before
+the test, and the local (re)definition takes no time. Also, we compensate
+for general overhead by subtracting the \type {none} timings.

+The timings are collected in \LUA\ tables and typeset afterwards, so there is no
+interference there either.
+
+{\em The timings are as usual a snapshot and just indications. The relative times

+that is not yet optimized. Also, especially with complex fonts like Husayni, not
+all shapers give the same result, although node mode and Uniscribe should be the
+same in most cases. A future (public) version of Husayni will play more safe and
+use less complex sequences of features.}

+\startchapter[title=Performance]
+
+\startsection[title=Introduction]
+
+This chapter is about performance. Although it concerns \LUATEX\ this text is
+only meant for \CONTEXT\ users. This is not because they ever complain about
+performance, on the contrary, I never received a complain from them. No, it's
+because it gives them some ammunition against the occasionally occurring nagging
+about the speed of \LUATEX\ (somewhere on the web or at some meeting). My
+experience is that in most such cases those complaining have no clue what they're
+talking about, so effectively we could just ignore them, but let's, for the sake
+of our users, waste some words on the issue.
+
+\stopsection
+
+\startsection[title=What performance]
+
+So what exactly does performance refer to? If you use \CONTEXT\ there are
+probably only two things that matter:
+
+\startitemize[packed]
+\startitem How long does one run take. \stopitem
+\startitem How many runs do I need. \stopitem
+\stopitemize
+
+Processing speed is reported at the end of a run in terms of seconds spent on the
+run, but also in pages per second. The runtime is made up out of three
+components:
+
+\startitemize[packed]
+\startitem start-up time \stopitem
+\startitem processing pages \stopitem
+\startitem finishing the document \stopitem
+\stopitemize
+
+The startup time is rather constant. Let's take my 2013 Dell Precision with
+i7-3840QM as reference. A simple
+
+\starttyping
+\starttext
+\stoptext
+\stoptyping
+
+document reports 0.4 seconds but as we wrap the run in an \type {mtxrun}
+management run we have an additional 0.3 overhead (auxiliary file handling, \PDF\
+viewer management, etc). This includes loading the Latin Modern font. With
+\LUAJITTEX\ these times are below 0.3 and 0.2 seconds. It might look like much
+overhead but in an edit|-|preview runs it feels snappy. One can try this:
+
+\starttyping
+\stoptext
+\stoptyping
+
+which bring down the time to about 0.2 seconds for both engines but as it doesn't
+do anything useful that is is no practice.
+
+Finishing a document is not that demanding because most gets flushed as we go.
+The more (large) fonts we use, the longer it takes to finish a document but on
+the average that time is not worth noticing. The main runtime contribution comes
+from processing the pages.
+
+Okay, this is not always true. For instance, if we process a 400 page book from
+2500 small \XML\ files with multiple graphics per page, there is a little
+overhead in loading the files and constructing the \XML\ tree as well as in
+inserting the graphics but in such cases one expects a few seconds more runtime. The
+\METAFUN\ manual has some 450 pages with over 2500 runtime generated \METAPOST\
+graphics. It has color, uses quite some fonts, has lots of font switches
+(verbatim too) but still one run takes only 18 seconds in stock \LUATEX\ and less
+that 15 seconds with \LUAJITTEX. Keep these numbers in mind if a non|-|\CONTEXT\
+users barks against the performance tree that his few page mediocre document
+takes 10 seconds to compile: the content, styling, quality of macros and whatever
+one can come up with all plays a role. Personally I find any rate between 10 and
+30 pages per second acceptable, and if I get the lower rate then I normally know
+pretty well that the job is demanding in all kind of aspects.
+
+Over time the \CONTEXT||\LUATEX\ combination, in spite of the fact that more
+functionality has been added, has not become slower. In fact, some subsystems
+have been sped up. For instance font handling is very sensitive for adding
+functionality. However, each version so far performed a bit better. Whenever some
+neat new trickery was added, at the same time improvements were made thanks to
+more insight in the matter. In practice we're not talking of changes in speed by
+large factors but more by small percentages. I'm pretty sure that most \CONTEXT\
+users never noticed. Recently a 15\endash30\% speed up (in font handling) was
+realized (for more complex fonts) but only when you use such complex fonts and
+pages full of text you will see a positive impact on the whole run.
+
+There is one important factor I didn't mention yet: the efficiency of the
+console. You can best check that by making a format (\typ {context --make en}).
+When that is done by piping the messages to a file, it takes 3.2 seconds on my
+laptop and about the same when done from the editor (\SCITE), maybe because the
+\LUATEX\ run and the log pane run on a different thread. When I use the standard
+console it takes 3.8 seconds in Windows 10 Creative update (in older versions it
+took 4.3 and slightly less when using a console wrapper). The powershell takes
+3.2 seconds which is the same as piping to a file. Interesting is that in Bash on
+Windows it takes 2.8 seconds and 2.6 seconds when piped to a file. Normal runs
+are somewhat slower, but it looks like the 64 bit Linux binary is somewhat faster
+than the 64 bit mingw version. \footnote {Long ago we found that \LUATEX\ is very
+sensitive to for instance the \CPU\ cache so maybe there are some differences due
+to optimization flags and|/|or the fact that bash runs in one thread and all file
+\IO\ in the main windows instance. Who knows.} Anyway, it demonstrates that when
+someone yells a number you need to ask what the conditions where.
+
+At a \CONTEXT\ meeting there has been a presentation about possible speed|-|up of
+a run for instance by using a separate syntax checker to prevent a useless run.
+However, the use case concerned a document that took a minute on the machine
+used, while the same document took a few seconds on mine. At the same meeting we
+also did a comparison of speed for a \LATEX\ run using \PDFTEX\ and the same
+document migrated to \CONTEXT\ \MKIV\ using \LUATEX\ (Harald K\"onigs \XML\
+torture and compatibility test). Contrary to what one might expect, the
+\CONTEXT\ run was significantly faster; the resulting document was a few
+gigabytes in size.
+
+\stopsection
+
+\startsection[title=Bottlenecks]
+
+I will discuss a few potential bottlenecks next. A complex integrated system like
+\CONTEXT\ has lots of components and some can be quite demanding. However, when
+something is not used, it has no (or hardly any) impact on performance. Even when
+we spend a lot of time in \LUA\ that is not the reason for a slow|-|down.
+Sometimes using \LUA\ results in a speedup, sometimes it doesn't matter. Complex
+mechanisms like natural tables for instance will not suddenly become less
+complex. So, let's focus on the \quotation {aspects} that come up in those
+complaints: fonts and \LUA. Because I only use \CONTEXT\ and occasionally test
+with the plain \TEX\ version that we provide, I will not explore the potential
+impact of using truckloads of packages, styles and such, which I'm sure of plays
+a role, but one neglected in the discussion.
+
+\startsubsubject[title=Fonts]
+
+According to the principles of \LUATEX\ we process (\OPENTYPE) fonts using \LUA.
+That way we have complete control over any aspect of font handling, and can, as
+to be expected in \TEX\ systems, provide users what they need, now and in the
+future. In fact, if we didn't had that freedom in \CONTEXT\ I'd probably already
+quit using \TEX\ a decade ago and found myself some other (programming) niche.
+
+After a font is loaded, part of the data gets passed to the \TEX\ engine so that
+it can do its work. For instance, in order to be able to typeset a paragraph,
+\TEX\ needs to know the dimensions of glyphs. Once a font has been loaded
+(that is, the binary blob) the next time it's fetched from a cache. Initial
+loading (and preparation) takes some time, depending on the complexity or size of
+the font. Loading from cache is close to instantaneous. After loading the
+dimensions are passed to \TEX\ but all data remains accessible for any desired
+usage. The \OPENTYPE\ feature processor for instance uses that data and \CONTEXT\
+for sure needs that data (fast accessible) for different purposes too.
+
+When a font is used in so called base mode, we let \TEX\ do the ligaturing and
+kerning. This is possible with simple fonts and features. If you have a critical
+workflow you might enable base mode, which can be done per font instance.
+Processing in node mode takes some time but how much depends on the font and
+script. Normally there is no difference between \CONTEXT\ and generic usage. In
+\CONTEXT\ we also have dynamic features, and the impact on performance depends on
+usage. In addition to base and node we also have plug mode but that is only used
+for testing and therefore not advertised.
+
+Every \type {\hbox} and every paragraph goes through the font handler. Because
+we support mixed modes, some analysis takes place, and because we do more in
+\CONTEXT, the generic analyzer is more light weight, which again can mean that a
+generic run is not slower than a similar \CONTEXT\ one.
+
+Interesting is that added functionality for variable and|/|or color fonts had no
+impact on performance. Runtime added user features can have some impact but when
+defined well it can be neglected. I bet that when you add additional node list
+handling yourself, its impact on performance is larger. But in the end what
+counts is that the job gets done and the more you demand the higher the price you
+pay.
+
+\stopsubsubject
+
+\startsubsubject[title=\LUA]
+
+The second possible bottleneck when using \LUATEX\ can be in using \LUA\ code.
+However, using that as argument for slow runs is laughable. For instance
+\CONTEXT\ \MKIV\ can easily spend half its time in \LUA\ and that is not making
+it any slower than \MKII\ using \PDFTEX\ doing equally complex things. For
+instance the embedded \METAPOST\ library makes \MKIV\ way faster than \MKII, and
+the built|-|in \XML\ processing capabilities in \MKIV\ can easily beat \MKII\
+\XML\ handling, apart from the fact that it can do more, like filtering by path
+and expression. In fact, files that take, say, half a minute in \MKIV, could as
+well have taken 15 minutes or more in \MKII\ (and imagine multiple runs then).
+
+So, for \CONTEXT\ using \LUA\ to achieve its objectives is mandate. The
+combination of \TEX, \METAPOST\ and \LUA\ is pretty powerful! Each of these
+components is really fast. If \TEX\ is your bottleneck, review your macros! When
+\LUA\ seems to be the bad, go over your code and make it better. Much of the
+\LUA\ code I see flying around doesn't look that efficient, which is okay because
+the interpreter is really fast, but don't blame \LUA\ beforehand, blame your
+coding (style) first. When \METAPOST\ is the bottleneck, well, sometimes not much
+can be done about it, but when you know that language well enough you can often
+make it perform better.
+
+For the record: every additional mechanism that kicks in, like character spacing
+(the ugly one), case treatments, special word and line trickery, marginal stuff,
+graphics, line numbering, underlining, referencing, and a few dozen more will add
+a bit to the processing time. In that case, in \CONTEXT, the font related runtime
+gets pretty well obscured by other things happening, just that you know.
+
+\stopsubsubject
+
+\stopsection
+
+\startsection[title=Some timing]
+
+Next I will show some timings related to fonts. For this I use stock \LUATEX\
+(second column) as well as \LUAJITTEX\ (last column) which of course performs
+much better. The timings are given in 3 decimals but often (within a set of runs)
+and as the system load is normally consistent in a set of test runs the last two
+decimals only matter in relative comparison. So, for comparing runs over time
+round to the first decimal. Let's start with loading a bodyfont. This happens
+once per document and normally one has only one bodyfont active. Loading involves
+definitions as well as setting up math so a couple of fonts are actually loaded,
+even if they're not used later on. A setup normally involves a serif, sans, mono,
+and math setup (in \CONTEXT). \footnote {The timing for Latin Modern is so low
+because that font is loaded already.}
+
+\environment onandon-speed-000
+
+\ShowSample{onandon-speed-000} % bodyfont
+
+There is a bit difference between the font sets but a safe average is 150 milli
+seconds and this is rather constant over runs.
+
+An actual font switch can result in loading a font but this is a one time overhead.
+Loading four variants (regular, bold, italic and bold italic) roughly takes the
+following time:
+
+\ShowSample{onandon-speed-001} % four variants
+
+Using them again later on takes no time:
+
+\ShowSample{onandon-speed-002} % four variants
+
+Before we start timing the font handler, first a few baseline benchmarks are
+shown. When no font is applied and nothing else is done with the node list we
+get:
+
+\ShowSample{onandon-speed-009}
+
+A simple monospaced, no features applied, run takes a bit more:
+
+\ShowSample{onandon-speed-010}
+
+Now we show a one font typesetting run. As the two benchmarks before, we just
+typeset a text in a \type {\hbox}, so no par builder interference happens. We use
+the \type {sapolsky} sample text and typeset it 100 times 4 (either of not with
+font switches).
+
+\ShowSample{onandon-speed-003}
+
+Much more runtime is needed when we typeset with four font switches. The garamond
+is most demanding. Actually we're not doing 4 fonts there because it has no bold,
+so the numbers are a bit lower than expected for this example. One reason for it
+being demanding is that it has lots of (contextual) lookups. The only comment I
+can make about that is that it also depends on the strategies of the font
+designer. Combining lookups saves space and time so complexity of a font is not
+always a good predictor for performance hits.
+
+% \ShowSample{onandon-speed-004}
+
+If we typeset paragraphs we get this:
+
+\ShowSample{onandon-speed-005}
+
+We're talking of some 275 pages here.
+
+\ShowSample{onandon-speed-006}
+
+There is of course overhead in handling paragraphs and pages:
+
+\ShowSample{onandon-speed-011}
+
+Before I discuss these numbers in more details two more benchmarks are
+shown. The next table concerns a paragraph with only a few (bold) words.
+
+\ShowSample{onandon-speed-007}
+
+The following table has paragraphs with a few mono spaced words
+typeset using \type{\type}.
+
+\ShowSample{onandon-speed-008}
+
+When a node list (hbox or paragraph) is processed, each glyph is looked at. One
+important property of \LUATEX\ (compared to \PDFTEX) is that it hyphenates the
+whole text, not only the most feasible spots. For the \type {sapolsky} snippet
+this results in 200 potential breakpoints, registered in an equal number of
+discretionary nodes. The snippet has 688 characters grouped into 125 words and
+because it's an English quote we're not hampered with composed characters or
+complex script handling. And, when we mention 100 runs then we actually mean
+400 ones when font switching and bodyfonts are compared
+
+\startnarrower
+    \showglyphs \showfontkerns
+    \input sapolsky \wordright{Robert M. Sapolsky}
+\stopnarrower
+
+In order to get substitutions and positioning right we need not only to consult
+streams of glyphs but also combinations with preceding pre or replace, or
+trailing post and replace texts. When a font has a bit more complex substitutions,
+as ebgaramond has, multiple (sometimes hundreds of) passes over the list are made.
+This is why the more complex a font is, the more runtime is involved.
+
+Another factor, one you could easily deduce from the benchmarks, is intermediate
+font switches. Even a few such switches (in the last benchmarks) already result
+in a runtime penalty. The four switch benchmarks show an impressive increase of
+runtime, but it's good to know that such a situation seldom happens. It's also
+important not to confuse for instance a verbatim snippet with a bold one. The
+bold one is indeed leading to a pass over the list, but verbatim is normally
+skipped because it uses a font that needs no processing. That verbatim or bold
+have the same penalty is mainly due to the fact that verbatim itself is costly:
+the text is picked up using a different catcode regime and travels through \TEX\
+and \LUA\ before it finally gets typeset. This relates to special treatments of
+spacing and syntax highlighting and such.
+
+Also keep in mind that the page examples are quite unreal. We use a layout with
+no margins, just text from edge to edge.

+So what is a realistic example? That is hard to say. Unfortunately no one ever
+asked us to typeset novels. They are rather brain dead products for a machinery
+so they process fast. On the mentioned laptop 350 word pages in Dejavu fonts can
+be processed at a rate of 75 pages per second with \LUATEX\ and over 100 pages
+per second with \LUAJITTEX . On a more modern laptop or professional server
+performance is of course better. And for automated flows batch mode is your
+friend. The rate is not much worse for a document in a language with a bit more
+complex character handling, take accents or ligatures. Of course \PDFTEX\ is
+faster on such a dumb document but kick in some more functionality and the
+advantage quickly disappears. So, if someone complains that \LUATEX\ needs 10 or
+more seconds for a simple few page document \unknown\ you can bet that when the
+fonts are seen as reason, that the setup is pretty bad. Personally I'd not waste
+time on such a complaint.
+
+\stopsection
+
+\startsection[title=Valid questions]
+
+Here are some reasonable questions that you can ask when someone complains to you
+about the slowness of \LUATEX:
+
+\startsubsubject[title={What engines do you compare?}]
+
+If you come from \PDFTEX\ you come from an 8~bit world: input and font handling
+are based on bytes and hyphenation is integrated into the par builder. If you use
+\UTF-8\ in \PDFTEX, the input is decoded by \TEX\ macros which carries a speed
+penalty. Because in the wide engines macro names can also be \UTF\ sequences,
+construction of macro names is less efficient too.
+
+When you try to use wide fonts, again there is a penalty. Now, if you use \XETEX\
+or \LUATEX\ your input is \UTF-8 which becomes something 32 bit internally. Fonts
+are wide so more resources are needed, apart from these fonts being larger and in
+need of more processing due to feature handling. Where \XETEX\ uses a library,
+\LUATEX\ uses its own handler. Does that have a consequence for performance? Yes
+and no. First of all it depends on how much time is spent on fonts at all, but
+even then the difference is not that large. Sometimes \XETEX\ wins, sometimes
+\LUATEX. One thing is clear: \LUATEX\ is more flexible as we can roll out our own
+solutions and therefore do more advanced font magic. For \CONTEXT\ it doesn't
+matter as we use \LUATEX\ exclusively and rely on the flexible font handler, also
+for future extensions. If really needed you can kick in a library based handler
+but it's (currently) not distributed as we loose other functionality which in
+turn would result in complaints about that fact (apart from conflicting with the
+strive for independence).
+
+There is no doubt that \PDFTEX\ is faster but for \CONTEXT\ it's an obsolete
+engine. The hard coded solutions engine \XETEX\ is also not feasible for
+\CONTEXT\ either. So, in practice \CONTEXT\ users have no choice: \LUATEX\ is
+used, but users of other macro packages can use the alternatives if they are not
+satisfied with performance. The fact that \CONTEXT\ users don't complain about
+speed is a clear signal that this is no issue. And, if you want more speed you
+can use \LUAJITTEX. \footnote {In plug mode we can actually test a library and
+experiments have shown that performance on the average is much worse but it can
+be a bit better for complex scripts, although a gain gets unnoticed in normal
+documents. So, one can decide to use a library but at the cost of much other
+functionality that \CONTEXT\ offers, so we don't support it.} In the last section
+the different engines will be compared in more detail.
+
+Just that you know, when we do the four switches example in plain \TEX\ on my
+laptop I get a rate of 40 pages per second, and for one font 180 pages per
+second. There is of course a bit more going on in \CONTEXT\ in page building and
+so, but the difference between plain and \CONTEXT\ is not that large.
+
+\stopsubsubject
+
+\startsubsubject[title={What macro package is used?}]
+
+If the answer is that when plain \TEX\ is used, a follow up question is: what
+variant? The \CONTEXT\ distribution ships with \type {luatex-plain} and that is
+our benchmark. If there really is a bottleneck it is worth exploring. But keep in
+mind that in order to be plain, not that much can be done. The \LUATEX\ part is
+just an example of an implementation. We already discussed \CONTEXT, and for
+\LATEX\ I don't want to speculate where performance hits might come from. When
+we're talking fonts, \CONTEXT\ can actually a bit slower than the generic (or
+\LATEX) variant because we can kick in more functionality. Also, when you compare
+macro packages, keep in mind that when node list processing code is added in that
+package the impact depends on interaction with other functionality and depends on
+the efficiency of the code. You can't compare mechanisms or draw general
+conclusions when you don't know what else is done!
+
+\stopsubsubject
+
+\startsubsubject[title={What do you load?}]
+
+Most \CONTEXT\ modules are small and load fast. Of course there can be exceptions
+when we rely on third party code; for instance loading tikz takes a a bit of
+time. It makes no sense to look for ways to speed that system up because it is
+maintained elsewhere. There can probably be gained a bit but again, no user
+complained so far.
+
+If \CONTEXT\ is not used, one probably also uses a large \TEX\ installations.
+File lookup in \CONTEXT\ is done differently and can can be faster. Even loading
+can be more efficient in \CONTEXT, but it's hard to generalize that conclusion.
+If one complains about loading fonts being an issue, just try to measure how much
+time is spent on loading other code.
+
+\stopsubsubject
+
+\startsubsubject[title={Did you patch macros?}]
+
+Not everyone is a \TEX pert. So, coming up with macros that are expanded many
+times and|/|or have inefficient user interfacing can have some impact. If someone
+complains about one subsystem being slow, then honestly demands to complain about
+other subsystems as well. You get what you ask for.
+
+\stopsubsubject
+
+\startsubsubject[title={How efficient is the code that you use?}]
+
+Writing super efficient code only makes sense when it's used frequently. In
+\CONTEXT\ most code is reasonable efficient. It can be that in one document fonts
+are responsible for most runtime, but in another document table construction can
+be more demanding while yet another document puts some stress on interactive
+features. When hz or protrusion is enabled then you run substantially slower
+anyway so when you are willing to sacrifice 10\% or more runtime don't complain
+about other components. The same is true for enabling \SYNCTEX: if you are
+willing to add more than 10\% runtime for that, don't wither about the same
+amount for font handling. \footnote {In \CONTEXT\ we use a \SYNCTEX\ alternative
+that is somewhat faster but it remains a fact that enabling more and more
+functionality will make the penalty of for instance font processing relatively
+small.}
+
+\stopsubsubject
+
+\startsubsubject[title={How efficient is the styling that you use?}]
+
+Probably the most easily overseen optimization is in switching fonts and color.
+Although in \CONTEXT\ font switching is fast, I have no clue about it in other
+macro packages. But in a style you can decide to use inefficient (massive) font
+switches. The effects can easily be tested by commenting bit and pieces. For
+instance sometimes you need to do a full bodyfont switch when changing a style,
+like assigning \type {\small\bf} to the \type {style} key in \type {\setuphead},
+but often using e.g.\ \type {\tfd} is much more efficient and works quite as
+well. Just try it.
+
+\stopsubsubject
+
+\startsubsubject[title={Are fonts really the bottleneck?}]
+
+We already mentioned that one can look in the wrong direction. Maybe once someone
+is convinced that fonts are the culprit, it gets hard to look at the real issue.
+If a similar job in different macro packages has a significant different runtime
+one can wonder what happens indeed.
+
+It is good to keep in mind that the amount of text is often not as large as you
+think. It's easy to do a test with hundreds of paragraphs of text but in practice
+we have whitespace, section titles, half empty pages, floats, itemize and similar
+constructs, etc. Often we don't mix many fonts in the running text either. So, in
+the end a real document is the best test.
+
+\stopsubsubject
+
+\startsubsubject[title={If you use \LUA, is that code any good?}]
+
+You can gain from the faster virtual machine of \LUAJITTEX. Don't expect wonders
+from the jitting as that only pays of for long runs with the same code used over
+and over again. If the gain is high you can even wonder how well written your
+\LUA\ code is anyway.
+
+\stopsubsubject
+
+\startsubsubject[title={What if they don't believe you?}]
+
+So, say that someone finds \LUATEX\ slow, what can be done about it? Just advice
+him or her to stick to tool used previously. Then, if arguments come that one
+also wants to use \UTF-8, \OPENTYPE\ fonts, a bit of \METAPOST, and is looking
+forward to using \LUA\ runtime, the only answer is: take it or leave it. You pay
+a price for progress, but if you do your job well, the price is not that large.
+Tell them to spend time on learning and maybe adapting and bark against their own
+tree before barking against those who took that step a decade ago. Most \CONTEXT\
+users took that step and someone still using \LUATEX\ after a decade can't be
+that stupid. It's always best to first wonder what one actually asks from \LUATEX,
+and if the benefit of having \LUA\ on board has an advantage. If not, one can
+just use another engine.
+
+Also think of this. When a job is slow, for me it's no problem to identify where
+the problem is. The question then is: can something be done about it? Well, I
+happily keep the answer for myself. After all, some people always need room to
+complain, maybe if only to hide their ignorance or incompetence. Who knows.
+
+\stopsubsubject
+
+\stopsection
+
+\startsection[title={Comparing engines}]
+
+The next comparison is to be taken with a grain of salt and concerns the state of
+affairs mid 2017. First of all, you cannot really compare \MKII\ with \MKIV: the
+later has more functionality (or a more advanced implementation of
+functionality). And as mentioned you can also not really compare \PDFTEX\ and the
+wide engines. Anyway, here are some (useless) tests. First a bunch of loads. Keep
+in mind that different engines also deal differently with reading files. For
+instance \MKIV\ uses \LUATEX\ callbacks to normalize the input and has its own
+readers. There is a bit more overhead in starting up a \LUATEX\ run and some
+functionality is enabled that is not present in \MKII. The format is also larger,
+if only because we preload a lot of useful font, character and script related
+data.

+In these measurements the accuracy is a few decimals but a pattern is visible. As
+expected \PDFTEX\ wins on simple documents but starts loosing when things get
+more complex. For these tests I used 64 bit binaries. A 32 bit \XETEX\ with
+\MKII\ performs the same as \LUAJITTEX\ with \MKIV, but a 64 bit \XETEX\ is
+actually quite a bit slower. In that case the mingw cross compiled \LUATEX\
+version does pretty well. A 64 bit \PDFTEX\ is also slower (it looks) that a 32
+bit version. So in the end, there are more factors that play a role. Choosing
+between \LUATEX\ and \LUAJITTEX\ depends on how well the memory limited
+\LUAJITTEX\ variant can handle your documents and fonts.
+
+Because in most of our recent styles we use \OPENTYPE\ fonts and (structural)
+features as well as recent \METAFUN\ extensions only present in \MKIV\ we cannot
+compare engines using such documents. The mentioned performance of \LUATEX\ (or

+It will be clear that when we use different fonts the numbers will also be
+different. And if you use a lot of runtime \METAPOST\ graphics (for instance for
+backgrounds), the \MKIV\ runs end up at the top. And when we process \XML\ it
+will be clear that going back to \MKII\ is no longer a realistic option. It must
+be noted that I occasionally manage to improve performance but we've now reached
+a state where there is not that much to gain. Some functionality is hard to
+compare. For instance in \CONTEXT\ we don't use much of the \PDF\ backend
+features because we implement them all in \LUA. In fact, even in \MKII\ already a
+done in \TEX, so in the end the speed difference there is not large and often in
+favour of \MKIV.
+
+For the record I mention that shipping out the about 1250 pages has some overhead
+too: about 2 seconds. Here \LUAJITTEX\ is 20\% more efficient which is an
+indication of quite some \LUA\ involvement. Loading the input files has an
+overhead of about half a second. Starting up \LUATEX\ takes more time that
+\PDFTEX\ and \XETEX, but that disadvantage disappears with more pages. So, in the
+end there are quite some factors that blur the measurements. In practice what
+matters is convenience: does the runtime feel reasonable and in most cases it
+does.
+
+If I would replace my laptop with a reasonable comparable alternative that one
+would be some 35\% faster (single threads on processors don't gain much per year).
+I guess that this is about the same increase in performance that \CONTEXT\
+\MKIV\ got in that period. I don't expect such a gain in the coming years so
+at some point we're stuck with what we have.
+
+\stopsection
+
+\startsection[title=Summary]
+
+So, how \quotation {slow} is \LUATEX\ really compared to the other engines? If we
+go back in time to when the first wide engines showed up, \OMEGA\ was considered
+to be slow, although I never tested that myself. Then, when \XETEX\ showed up,
+there was not much talk about speed, just about the fact that we could use
+\OPENTYPE\ fonts and native \UTF\ input. If you look at the numbers, for sure you
+can say that it was much slower than \PDFTEX. So how come that some people
+complain about \LUATEX\ being so slow, especially when we take into account that
+it's not that much slower than \XETEX, and that \LUAJITTEX\ is often faster that
+\XETEX. Also, computers have become faster. With the wide engines you get more
+functionality and that comes at a price. This was accepted for \XETEX\ and is
+also acceptable for \LUATEX. But the price is nto that high if you take into
+account that hardware performs better: you just need to compare \LUATEX\ (and
+\XETEX) runtime with \PDFTEX\ runtime 15 years ago.
+
+As a comparison, look at games and video. Resolution became much higher as did
+color depth. Higher frame rates were in demand. Therefore the hardware had to
+become faster and it did, and as a result the user experience kept up. No user
+will say that a modern game is slower than an old one, because the old one does
+500 frames per second compared to some 50 for the new game on the modern
+hardware. In a similar fashion, the demands for typesetting became higher:
+\UNICODE, \OPENTYPE, graphics, \XML, advanced \PDF, more complex (niche)
+typesetting, etc. This happened more or less in parallel with computers becoming
+more powerful. So, as with games, the user experience didn't degrade with
+demands. Comparing \LUATEX\ with \PDFTEX\ is like comparing a low res, low frame
+rate, low color game with a modern one. You need to have up to date hardware and
+even then, the writer of such programs need to make sure it runs efficient,
+simply because hardware no longer scales like it did decades ago. You need to
+look at the larger picture.

+\startsubject[title=Introduction]
+
+History shows the tendency to recycle ideas. Often quite some effort is made by
+historians to figure out what really happened, not just long ago, when nothing
+was written down and we have to do with stories or pictures at most, but also in
+recent times. Descriptions can be conflicting, puzzling, incomplete, partially
+lost, biased, \unknown
+
+Just as language was invented (or evolved) several times, so were scripts. The
+same might be true for rendering scripts on a medium. Semaphores came and went
+within decades and how many people know now that they existed and that encryption
+was involved? Are the old printing presses truly the old ones, or are older
+examples simply gone? One of the nice aspects of the internet is that one can now
+more easily discover similar solutions for the same problem, but with a different
+(and independent) origin.
+
+So, how about this \quotation {new big thing} in font technology: variable fonts.
+In this case, history shows that it's not that new. For most \TEX\ users the
+names \METAFONT\ and \METAPOST\ will ring bells. They have a very well documented
+history so there is not much left to speculation. There are articles, books,
+pictures, examples, sources, and more around for decades. So, the ability to
+change the appearance of a glyph in a font depending on some parameters is not
+new. What probably {\em is} new is that creating variable fonts is done in the
+natural environment where fonts are designed: an interactive program. The
+\METAFONT\ toolkit demands quite some insight in programming shapes in such a way
+that one can change look and feel depending on parameters. There are not that
+many meta fonts made and one reason is that making them requires a certain mind-
+and skill set. On the other hand, faster computers, interactive programs,
+evolving web technologies, where rea|l|-time rendering and therefore more or less
+real-time tweaking of fonts is a realistic option, all play a role in acceptance.
+
+But do interactive font design programs make this easier? You still need to be
+able to translate ideas into usable beautiful fonts. Taking the common shapes of
+glyphs, defining extremes and letting a program calculate some interpolations
+will not always bring good results. It's like morphing a picture of your baby's
+face into yours of old age (or that of your grandparent): not all intermediate
+results will look great. It's good to notice that variable fonts are a revival of
+existing techniques and ideas used in, for instance, multiple master fonts. The
+details might matter even more as they can now be exaggerated when some
+transformation is applied.
+
+There is currently (March 2017) not much information about these fonts so what I
+say next may be partially wrong or at least different from what is intended. The
+perspective will be one from a \TEX\ user and coder. Whatever you think of them,
+these fonts will be out there and for sure there will be nice examples
+circulating soon. And so, when I ran into a few experimental fonts, with
+\POSTSCRIPT\ and \TRUETYPE\ outlines, I decided to have a look at what is inside.
+After all, because it's visual, it's also fun to play with. Let's stress that at
+the moment of this writing I only have a few simple fonts available, fonts that
+are designed for testing and not usage. Some recommended tables were missing and
+no complex \OPENTYPE\ features are used in these fonts.
+
+\stopsubject
+
+\startsubject[title=The specification]
+
+I'm not that good at reading specifications, first of all because I quickly fall
+asleep with such documents, but most of all because I prefer reading other stuff
+(I do have lots of books waiting to be read). I'm also someone who has to play
+with something in order to understand it: trial and error is my modus operandi.
+Eventually it's my intended usage that drives the interface and that is when
+everything comes together.
+
+Exploring this technology comes down to: locate a font, get the \OPENTYPE\ 1.8
+specification from the \MICROSOFT\ website, and try to figure out what is in the
+font. When I had a rough idea the next step was to get to the shapes and see if I
+could manipulate them. Of course it helped that in \CONTEXT\ we already can load
+fonts and play with shapes (using \METAPOST). I didn't have to install and learn
+other programs. Once I could render them, in this case by creating a virtual font
+with inline \PDF\ literals, a next step was to apply variation. Then came the
+first experiments with a possible user interface. Seeing more variation then
+drove the exploration of additional properties needed for typesetting, like
+features.
+
+The main extension to the data packaged in a font file concerns the (to be
+discussed) axis along which variable fonts operate and deltas to be applied to
+coordinates. The \type {gdef} table has been extended and contains information
+that is used in \type {gpos} features. There are new \type {hvar}, \type {vvar}
+and \type {mvar} tables that influence the horizontal, vertical and general font
+dimensions. The \type {gvar} table is used for \TRUETYPE\ variants, while the
+\type {cff2} table replaces the \type {cff} table for \OPENTYPE\ \POSTSCRIPT\
+outlines. The \type {avar} and \type {stat} tables contain some
+meta|-|information about the axes of variations.
+
+It must be said that because this is new technology the information in the
+standard is not always easy to understand. The fact that we have two rendering
+techniques, \POSTSCRIPT\ \type {cff} and \TRUETYPE\ \type {ttf}, also means that
+we have different information and perspectives. But this situation is not much
+different from \OPENTYPE\ standards a few years ago: it takes time but in the end
+I will get there. And, after all, users also complain about the lack of
+documentation for \CONTEXT, so who am I to complain? In fact, it will be those
+\CONTEXT\ users who will provide feedback and make the implementation better in
+the~end.
+
+\stopsubject
+
+\startsubject[title=Loading]
+
+Before we discuss some details, it will be useful to summarize what the font
+loader does when a user requests a font at a certain size and with specific
+features enabled. When a font is used the first time, its binary format is
+converted into a form that makes it suitable for use within \CONTEXT\ and
+therefore \LUATEX. This conversion involves collecting properties of the font as
+a whole (official names, general dimensions like x-height and em-width, etc.), of
+glyphs (dimensions, \UNICODE\ properties, optional math properties), and all
+kinds of information that relates to (contextual) replacements of glyphs (small
+caps, oldstyle, scripts like Arabic) and positioning (kerning, anchoring marks,
+etc.). In the \CONTEXT\ font loader this conversion is done in \LUA.
+
+The result is stored in a condensed format in a cache and the next time the font
+is needed it loads in an instant. In the cached version the dimensions are
+untouched, so a font at different sizes has just one copy in the cache. Often a
+font is needed at several sizes and for each size we create a copy with scaled
+glyph dimensions. The feature-related dimensions (kerning, anchoring, etc.)\ are
+shared and scaled when needed. This happens when sequences of characters in the
+node list get converted into sequences of glyphs. We could do the same with glyph
+dimensions but one reason for having a scaled copy is that this copy can also
+contain virtual glyphs and these have to be scaled beforehand. In practice there
+are several layers of caching in order to keep the memory footprint within
+reasonable bounds. \footnote {In retrospect one can wonder if that makes sense;
+just look at how much memory a browser uses when it has been open for some time.
+In the beginning of \LUATEX\ users wondered about caching fonts, but again, just
+look at what amounts browsers cache: it gets pretty close to the average amount
+of writes that a \SSD\ can handle per day within its guarantee.}
+
+When the font is actually used, interaction between characters is resolved using
+the feature|-|related information. When for instance two characters need to be
+kerned, a lookup results in the injection of a kern, scaled from general
+dimensions to the current size of the font.
+
+When the outlines of glyphs are needed in \METAFUN\ the font is also converted
+from its binary form to something in \LUA, but this time we filter the shapes.
+For a \type {cff} this comes down to interpreting the \type {charstrings} and
+reducing the complexity to \type {moveto}, \type {lineto} and \type {curveto}
+operators. In the process subroutines are inlined. The result is something that
+\METAPOST\ is happy with but that also can be turned into a piece of a \PDF.
+
+We now come to what a variable font actually is: a basic design which is
+transformed along one or more axes. A simple example is wider shapes:
+
+\startlinecorrection
+\startMPcode
+for i=1 upto 4 :
+    fill fullsquare xyscaled (i*.5cm,1cm) shifted (i*2.5*cm,0) withcolor "darkgray";
+    fill fullcircle xyscaled (2.5mm,2.5mm) shifted (i*2.5*cm,0) withcolor "lightgray" ;
+endfor ;
+\stopMPcode
+\stoplinecorrection
+
+We can also go taller and retain the width:
+
+\startlinecorrection
+\startMPcode
+for i=1 upto 4 :
+    fill fullsquare xyscaled (1cm,i*.5cm) shifted (i*2.5*cm,0) withcolor "darkgray";
+    fill fullcircle xyscaled (2.5mm,2.5mm) shifted (i*2.5*cm,0) withcolor "lightgray" ;
+endfor ;
+\stopMPcode
+\stoplinecorrection
+
+Here we have a linear scaling but glyphs are not normally done that way. There
+are font collections out there with lots of intermediate variants (say from light
+to heavy) and it's more profitable to sell each variant independently. However,
+there is often some logic behind it, probably supported by programs that
+designers use, so why not build that logic into the font and have one file that
+represents many intermediate forms. In fact, once we have multiple axes, even
+when the designer has clear ideas of the intended usage, nothing will prevent
+users from tinkering with the axis properties in ways that will fulfil their
+demands but hurt the designers eyes. We will not discuss that dilemma here.
+
+When a variable font follows the route described above, we face a problem. When
+you load a \TRUETYPE\ font it will just work. The glyphs are packaged in the same
+format as static fonts. However, a variable font has axes and on each axis a
+value can be set. Each axis has a minimum, maximum and default. It can be that
+the default instance also assumes some transformations are applied. The standard
+recommends adding tables to describe these things but the fonts that I played
+with each lacked such tables. So that leaves some guesswork. But still, just
+loading a \TRUETYPE\ font gives some sort of outcome, although the dimensions
+(widths) might be weird due to lack of a (default) axis being applied.
+
+An \OPENTYPE\ font with \POSTSCRIPT\ outlines is different: the internal \type
+{cff} format has been upgraded to \type {cff2} which on the one hand is less
+complicated but on the other hand has a few new operators \emdash\ which results
+in programs that have not been adapted complaining or simply quitting on them.
+
+One could argue that a font is just a resource and that one only has to pass it
+along but that's not what works well in practice. Take \LUATEX. We can of course
+load the font and apply axis vales so that we can process the document as we
+normally do. But at some point we have to create a \PDF. We can simply embed the
+\TRUETYPE\ files but no axis values are applied. This is because, even if we add
+the relevant information, there is no way in current \PDF\ formats to deal with
+it. For that, we should be able to pass all relevant axis|-|related information
+as well as specify what values to use along these axes. And for \TRUETYPE\ fonts
+this information is not part of the shape description so then we in fact need to
+filter and pass more. An \OPENTYPE\ \POSTSCRIPT\ font is much cleaner because
+there we have the information needed to transform the shape mostly in the glyph
+description. There we only need to carry some extra information on how to apply
+these so|-|called blend values. The region|/|axis model used there only demands
+passing a relatively simple table (stripped down to what we need). But, as said
+above, \type {cff2} is not backward-compatible so a viewer will (currently)
+simply not show anything.
+
+Recalling how we load fonts, how does that translate with variable changes? If we
+have two characters with glyphs that get transformed and that have a kern between
+them, the kern may or may not transform. So, when we choose values on an axis,
+then not only glyph properties change but also relations. We no longer can share
+positional information and scale afterwards because each instance can have
+different values to start with. We could carry all that information around and
+apply it at runtime but because we're typesetting documents with a static design
+it's more convenient to just apply it once and create an instance. We can use the
+same caching as mentioned before but each chosen instance (provided by the font
+or made up by user specifications) is kept in the cache. As a consequence, using
+a variable font has no overhead, apart from initial caching.
+
+So, having dealt with that, how do we proceed? Processing a font is not different
+from what we already had. However, I would not be surprised if users are not
+always satisfied with, for instance, kerning, because in such fonts a lot of care
+has to be given to this by the designer. Of course I can imagine that programs
+used to create fonts deal with this, but even then, there is a visual aspect to
+it too. The good news is that in \CONTEXT\ we can manipulate features so in
+theory one can create a so|-|called font goodie file for a specific instance.
+
+\stopsubject
+
+\startsubject[title=Shapes]
+
+For \OPENTYPE\ \POSTSCRIPT\ shapes we always have to do a dummy rendering in
+order to get the right bounding box information. For \TRUETYPE\ this information
+is already present but not when we use a variable instance, so I had to do a bit
+of coding for that. Here we face a problem. For \TEX\ we need the width, height
+and depth of a glyph. Consider the following case:
+
+\startlinecorrection
+\startMPcode
+path p ; p := fullcircle xysized (3cm,2cm) ;
+fill p
+    withcolor "lightgray" ;
+draw boundingbox currentpicture
+    withpen pencircle scaled .5mm
+    withcolor "darkgray" ;
+setbounds currentpicture to p ;
+draw boundingbox currentpicture
+    leftenlarged 2mm rightenlarged 5mm ;
+\stopMPcode
+\stoplinecorrection
+
+The shape has a bounding box that fits the shape. However, its left corner is not
+at the origin. So, when we calculate a tight bounding box, we cannot use it for
+actually positioning the glyph. We do use it (for horizontal scripts) to get the
+height and depth but for the width we depend on an explicit value. In \OPENTYPE\
+\POSTSCRIPT\ we have the width available and how the shape is positioned relative
+to the origin doesn't much matter. In a \TRUETYPE\ shape a bounding box is part
+of the specification, as is the width, but for a variable font one has to use
+so-called phantom points to recalculate the width and the test fonts I had were
+not suitable for investigating this.
+
+At any rate, once I could generate documents with typeset text using variable
+fonts it became time to start thinking about a user interface. A variable font
+can have predefined instances but of course a user also wants to mess with axis
+values. Take one of the test fonts: Adobe Variable Font Prototype. It has several
+instances:
+
+\unexpanded\def\SampleFont#1#2#3%
+ {\NC #2
+  \NC \definedfont[name:#1#3*default]It looks like this!
+      \normalexpanded{\noexpand\NC\currentfontinstancespec}
+  \NC \NR}
+
+\starttabulate[|||T|]

+\stoptabulate
+
+Such an instance is accessed with:
+
+\starttyping
+\definefont
+  [MyLightFont]
+  [name:adobevariablefontprototypelight*default]
+\stoptyping
+
+The Avenir Next variable demo font (currently) provides:

+Before we continue I will show a few examples of variable shapes. Here we use some
+\METAFUN\ magic. Just take these definitions for granted.

+
+The results are shown in \in {figure} [fig:whatever:1]. What we see here is that
+as long as we fill the shape everything will look as expected but using an
+outline only won't. The crucial (control) points are moved to different locations
+and as a result they can end up inside the shape. Giving up outlines is the price
+we evidently need to pay. Of course this is not unique for variable fonts
+although in practice static fonts behave better. To some extent we're back to
+where we were with \METAFONT\ and (for instance) Computer Modern: because these
+originate in bitmaps (and probably use similar design logic) we also can have
+overlap and bits and pieces pasted together and no one will notice that. The
+first outline variants of Computer Modern also had such artifacts while in the
+static Latin Modern successors, outlines were cleaned up.
+

+        {\getbuffer[d]} {c}
+    \stopcombination
+\stopplacefigure
+
+The fact that we need to preprocess an instance but only know how to do that when
+we have gotten the information about axis values from the font means that the
+font handler has to be adapted to keep caching correct. Another definition is:
+
+\starttyping
+\definefontfeature
+  [lightdefault]
+  [default]
+  [axis={weight:230,contrast:50}]
+
+\definefont
+  [MyLightFont]
+  [name:adobevariablefontprototype*lightdefault]
+\stoptyping
+
+Here the complication is that where normally features are dealt with after
+loading, the axis feature is part of the preparation (and caching). If you want
+the virtual font solution you can do this:
+
+\starttyping
+\definefontfeature
+  [inlinelightdefault]
+  [default]
+  [axis={weight:230,contrast:50},
+   variableshapes=yes]
+
+\definefont
+  [MyLightFont]
+  [name:adobevariablefontprototype*inlinelightdefault]
+\stoptyping
+
+When playing with these fonts it was hard to see if loading was done right. For
+instance not all values make sense. It is beyond the scope of this article, but
+axes like weight, width, contrast and italic values get applied differently to
+so|-|called regions (subspaces). So say that we have an $x$ coordinate with value
+$50$. This value can be adapted in, for instance, four subspaces (regions), so we
+actually get:
+
+\startformula
+    x^\prime = x
+             + s_1 \times x_1
+             + s_2 \times x_2
+             + s_3 \times x_3
+             + s_4 \times x_4
+\stopformula
+
+The (here) four scale factors $s_n$ are determined by the axis value. Each axis
+has some rules about how to map the values $230$ for weight and $50$ for contrast
+to such a factor. And each region has its own translation from axis values to
+these factors. The deltas $x_1,\dots,x_4$ are provided by the font. For a
+\POSTSCRIPT|-|based font we find sequences like:
+
+\starttyping
+1 <setvstore>
+120 [10 -30 40 -60] 1 <blend> ... <operator>
+100 120 [10 -30 40 -60] [30 -10 -30 20] 2 <blend> .. <operator>
+\stoptyping
+
+A store refers to a region specification. From there the factors are calculated
+using the chosen values on the axis. The deltas are part of the glyphs
+specification. Officially there can be multiple region specifications, but how
+likely it is that they will be used in real fonts is an open question.
+
+For \TRUETYPE\ fonts the deltas are not in the glyph specification but in a
+dedicated \type {gvar} table.
+
+\starttyping
+apply x deltas [10 -30 40 -60] to x 120
+apply y deltas [30 -10 -30 20] to y 100
+\stoptyping
+
+Here the deltas come from tables outside the glyph specification and their
+application is triggered by a combination of axis values and regions.
+
+The following two examples use Avenir Next Variable and demonstrate that kerning
+is adapted to the variant.
+
+\startbuffer
+\definefontfeature
+  [default:shaped]
+  [default]
+  [axis={width:10}]

+
+\startsubject[title=Embedding]
+
+Once we're done typesetting and a \PDF\ file has to be created there are three
+possible routes:
+
+\startitemize
+    \startitem
+        We can embed the shapes as \PDF\ images (inline literal) using virtual
+        font technology. We cannot use so|-|called xforms here because we want to
+        support color selectively in text.
+    \stopitem
+    \startitem
+        We can wait till the \PDF\ format supports such fonts, which might happen
+        but even then we might be stuck for years with viewers getting there. Also
+        documents need to get printed, and when printer support might
+        arrive is another unknown.
+    \stopitem
+    \startitem
+        We can embed a regular font with shapes that match the chosen values on the
+        axis. This solution is way more efficient than the first.
+    \stopitem
+\stopitemize
+
+Once I could interpret the right information in the font, the first route was the
+way to go. A side effect of having a converter for both outline types meant that
+it was trivial to create a virtual font at runtime. This option will stay in
+\CONTEXT\ as pseudo|-|feature \type {variableshapes}.
+
+When trying to support variable fonts I tried to limit the impact on the backend
+code. Also, processing features and such was not touched. The inclusion of the
+right shapes is done via a callback that requests the blob to be injected in the
+\type {cff} or \type {glyf} table. When implementing this I actually found out
+that the \LUATEX\ backend also does some juggling of charstrings, to serve the
+purpose of inlining subroutines. In retrospect I could have learned a few tricks
+faster by looking at that code but I never realized that it was there. Looking at
+the code again, it strikes me that the whole inclusion could be done with \LUA\
+code and some day I will give that a try.
+
+\stopsubject
+
+\startsubject[title=Conclusion]
+
+When I first heard about variable fonts I was confident that when they showed up
+they could be supported. Of course a specimen was needed to prove this. A first
+implementation demonstrates that indeed it's no big deal to let \CONTEXT\ with
+\LUATEX\ handle such fonts. Of course we need to fill in some gaps which can be
+done once we have complete fonts. And then of course users will demand more
+control. In the meantime the helper script that deals with identifying fonts by
+name has been extended and the relevant code has been added to the distribution.
+At some point the \CONTEXT\ Garden will provide the \LUATEX\ binary that has the
+callback.
+
+I end with a warning. On the one hand this technology looks promising but on the
+other hand one can easily get lost. Probably most such fonts operate over a
+well|-|defined domain of values but even then one should be aware of complex
+interactions with features like positioning or replacements. Not all combinations
+can be tested. It's probably best to stick to fonts that have all the relevant
+tables and don't depend on properties of a specific rendering technology.
+
+Although support is now present in the core of \CONTEXT\ the official release
+will happen at the \CONTEXT\ meeting in 2017. By then I hope to have tested more
+fonts. Maybe the interface has also been extended by then because after all,
+\TEX\ is about control.

+{\em This manual as well as the mechanism it describes is under construction. Don't
+use page columns in production. Experimenting is of course fine.}
+
+The \TEX\ engine is a progressive typesetter: it takes input and does something
+with it and can do that for quite a while. It can process massive input and
+produce massive output. In that process it never looks back. Now, it is of course
+possible to collect content and delay some aspects of the rendering but to what
+extent that content can be manipulated is limited. In \LUATEX\ one can do a bit
+more but even then the basic typesetting process is mostly linear.
+
+When a text gets typeset there are several properties that play a role:
+
+\startitemize
+\startitem
+    the width of the lines in a paragraph which is the main unit of processing
+\stopitem
+\startitem
+    the target height of what gets output, normally this is the height of the
+    text area, excluding headers and footers
+\stopitem
+\startitem
+    the parameters that determine when the so called output routine gets called,
+    for instance successive broken lines, widow and club penalties
+\stopitem
+\startitem
+    the presence of so called inserts, for instance footnotes or floating bodies
+\stopitem
+\startitem
+    the space between lines and paragraphs
+\stopitem
+\startitem
+    explicitly entered elements or spacing or injected by macros hooked into for
+    instance \type {\everypar}
+\stopitem
+\stopitemize
+
+It is important to realize that \TEX\ has no concept of what a page is. It takes
+input and occasionally hand over the intermediate result to the output routine.
+There decisions are made to flush out a page, either of not with ornaments like
+headers, footers, content left over from previous encounters, footnotes as well
+as maybe specific trickery liked by the backend that targets at some viewer.
+
+That said, so called multi|-|column layouts are {\em not} part of the concepts
+present in \TEX. As far as the engine is concerned there is only one column.
+Among the reasons for not having a native mechanism for columns is that it is
+very hard to come up with a mechanism for splitting them in ways that suits
+everybody. In fact, the amount of control needed would make such a mechanism very
+complex and still limited. You can compare this to math typesetting. That
+subspace has some fixed characteristics if only because otherwise mathematicians
+could not communicate. However, there is some control over spacing and one can to
+some extend intervene. In \LUATEX\ some of the hard coded properties are made
+configureable but still one gets pretty much what the engine considers right.
+Such an approach would not work with columns. In fact, it doesn't even work well
+with tables, for which \TEX\ provides the alignment mechanism: different kind of
+tables demand different solutions, which is why in \CONTEXT\ we have old
+fashioned tables, tabulated tables (that span pages and can contain paragraphs),
+natural as well as extreme tables that resemble \HTML\ tables, line tables and
+framed tables.
+
+So, when we want to support columns we need to write something in \TEX\ lingua
+and for that the \type {\vsplit} operation can be of help. So far we have in
+\CONTEXT\ four mechanisms:
+
+\startitemize[n]
+\startitem
+    the original \MKII\ mechanism that permits mixed single and multi|-|column
+    text flows, with limited support for floating bodies
+\stopitem
+\startitem
+    a reimplementation of mixed columns in a mix of \TEX\ and \LUA, a bit better
+    with balancing and penalties for keeping section heads with the text, but
+    with very limited support for floating bodies; it works ok with grids
+\stopitem
+\startitem
+    a reimplementation of \MKII\ columnsets, a mechanism that is meant for
+    magazine like layouts where floats can span columns and positioned at will:
+    this one assumes relative simple text flows but as a bonus provides spreads;
+    this one is strongly grid based
+\stopitem
+\startitem
+    page based columns, where we use the normal (single column) page builder to
+    collect columns that then get combined into a page: this one is quite robust
+    but one has to keep an eye on floats as we don't span across columns
+    otherwise than in top or bottom floats but, on the other hand, one can use so
+    called side floats; this one is still experimental
+\stopitem
+\stopitemize
+
+Given specific demands one can come up with alternatives but it's very hard to
+combine all demands into one mechanismn simply because anything can be part of
+the text flow. Because it is not much fun to write such mechanisms and because
+no project ever pays for fundamental development, one just has to accept what
+\CONTEXT\ provides, be it with limitations.
+
+The first mechanism is more or less obsolete and replaced by the second. For
+instance, we now use the second one when we have an itemize that demands columns.
+I must admit that I don't like columns and never use them. I was involved in
+projects where the designer wanted columns but in the end the complexity of the
+content didn't work well with that that decision: inconsistent whitespace (due to
+many small sections, lots of images, many tables, math formulas, etc) as well as
+the result having more pages that the single column variant with side and margin
+floats. Occasionally I use columned itemize or columned tables of contents and of
+course registers are often in columns.
+
+One can wonder why columns are supported anyway. It's mostly useful for
+newspapers that have wide pages or journals that have small print. For magazines
+and special layout it's fine too although it can look bad when columns are narrow
+and fancy layout tricks are used. I guess that at some point their use will
+disappear. A document on a phone or tablet is one narrow columns. An internet
+page is one long column. A printed book, given that there will be such items in
+the future is normally typeset in one column. And journals as well as newspapers
+more and more get replaced by media that better serve their purpose. So, apart
+from an intellectual challenge, implementing extensive multi|-|column support is
+a waste of energy. Which is why we can accept limitations.
+
+\stopchapter
+
+\startchapter[title=Just text]
+
+As with the other mechanism you can define a column instance and use that later.
+You can also directly pass the settings with the \type {\startpagecolumns} command
+but best is to define an instance.
+
+\FourPages{pagecolumns-001}
+
+\ShowFile{pagecolumns-001}
+
+We always start at a new page and end on a new one. Footnotes and such don't span
+columns and we don't balance. When the number of columns equals one you get the
+normal routine but with the requested settings.
+
+\stopchapter
+
+\startchapter[title=Floats]
+
+You can have floating bodies in columns. When a float doesn't fit it will be
+flushed at the top of the next page.
+
+\FourPages{pagecolumns-002}
+
+\ShowFile{pagecolumns-002}
+
+\SixPages{pagecolumns-007}
+
+\ShowFile{pagecolumns-007}
+
+Side floats are also supported but we don't treat them special so you get the
+same behaviour as with single column layouts.

+   reference=ch:cite]
+
+The \index {style+APA}APA Style Guide as well as good practice demand that
+\emphasis {all} references appearing in the bibliography be cited at least once
+in the text (and, of course, all citations must have a corresponding
+bibliographical reference). Other publishing styles, textbooks in particular,
+might additionally include lists of general references for \quote {further
+reading} (and these lists might sometimes be split into sections according to
+subject). An author may, in contrast, choose not to interrupt a text with many
+citations, nevertheless, including a list of references. Furthermore, one might
+refer in the text to certain works that need not necessarily be accompanied by a
+full bibliography listing (for example, \Name {Darwin} {C.}'s \emph {Origin}).
+\startfootnote \textcite[entry] [default::Darwin1859] \stopfootnote Thus, a
+system providing tools to handle bibliographies needs to be flexible.
+
+A good, general reference on bibliography practice (in the English language),
+independent of any particular specification, can be found in \cite [title]
+[default::vanLeunen1992] \cite [default::vanLeunen1992]. Note that rules and
+traditions may differ slightly in other languages and cultures.
+
+The examples of bibliography listings of the previous chapter were simplified by
+the fact that the entire bibliographical dataset was rendered. In practice, the
+same dataset source(s) could be used over many documents, and the dataset might
+contain many more references than are used in any one document. That is, the data
+source might be more complete than the final rendered bibliography list or lists.
+The mechanism of citation allows you to select references from the dataset(s) to
+build the list rendering as well as to place a indicator of the reference (or
+not) in the text of the document corresponding to a list entry (a publication).
+These citation renderings can be of many forms.
+
+A citation is normally pretty short as its main purpose is to refer uniquely to a
+more detailed description. But, there are several ways to refer, which is why the
+citation subsystem is configurable and extensible. Just look at the following
+commands:

+These examples introduce the concept of \Index {namespace}s that is extensively

+from the root namespace; similarly, the \TEXcode {default} specification will
+inherit elements from the \TEXcode {cite} namespace, but will be distinct from
+the \TEXcode {apa} specification's \TEXcode {cite} namespace, and so forth.

+\startaside
+Note that the \MKII\ module based on \Tindex {bibtex} allowed the use of curly
+brackets enclosing the \Index {tag} (for reasons of backward compatibility with
+traditional \LATEX\ practice). A side|-|effect made this a bit picky about spaces
+between its arguments, the first of which is optional. We have chosen to remove
+this restriction through the use of standard \CONTEXT\ syntax using square
+brackets (reserving curly brackets to usually be used to enclose text that is to
+be typeset).
+
+The system will tolerate the \Index {depreciated} syntax \cindex {cite}\TEXcode
+{\cite{tag}}, but this practice is to be strongly discouraged and cannot be mixed
+with any other options.
+\stopaside
+
+The most commonly used citation variants (or alternatives) are \TEXcode {num} and
+\TEXcode {authoryear} introduced above. The first is typically employed in
+conjunction with a numbered bibliography list, usually sorted in the citation
+order in the text; the second is typically used in conjunction with a
+bibliography list sorted by author and year of publication.
+
+Other citation variants may be quite useful, even when used in the context of the
+above standard schemes. One such example would be \Cindex {cite}\TEXcode
+{[title][tag]} that can be used to include the title of the work in the running
+text (as can be seen earlier in \in {section} [sec:styles]; another one is
+\cindex {cite}\TEXcode {\cite[year][tag]} that can be used to include the
+publication date and \cindex {cite}\TEXcode {\cite[author][tag]} can be used to
+extract the authors' names. These are examples of a general rule where \cindex
+{cite}\TEXcode {\cite[field][tag]} will return the contents of the given field
+for an entry, if the entry contains such a field.
+
+The variants \TEXcode {textnum} and \TEXcode {authoryears} are intended to be
+used in the running text when the reference becomes part of the syntax of the
+sentence: typically, they will not be set|-|off by parenthesis, for example.
+
+\startaside
+The name \TEXcode {authoryears} (with an \quote{s}) is a shorthand that was used
+in \MKII. Whereas its name is not immediately obvious at first view, in practice
+it is a quite convenient variant of \TEXcode {authoryear} that differs only in
+the style of punctuation, thus its place in a sentence structure.
+\stopaside
+
+Notice that in the example \TEXcode{\cite[template::Chen:1988:IPP]} shown above,
+the \TEXcode {tag} was prefixed with an alternate dataset name (\tindex
+{::}\TEXcode {template::}) rather than to the default \TEXcode {dataset=example}
+that was specified in the \Cindex {setupbtx} command earlier. The reason behind
+the double|-|colon syntax should be made obvious here (where the \Index {tag}
+itself uses single colons).
+
+In the last of the examples shown above, \TEXcode{\cite[entry][article]}, the
+full rendered bibliographic entry gets placed.
+
+Unless the placed rendering uses \TEXcode {method=dataset}, only publications
+that are explicitly cited will end up in the lists. You can force a citation into
+a list using \Cindex {usecitation}, for example:
+
+\cindex{usecitation}
+
+\startTEX
+\usecitation[patent]
+\stopTEX
+
+This command has two synonyms: \Cindex {nocite} and \Cindex {nocitation} so you
+can choose whatever fits you best.
+
+\cindex   {nocite}
+\showsetup[nocite]
+
+\cindex   {nocitation}
+\showsetup[nocitation]
+
+\cindex   {usecitation}
+\showsetup[usecitation]
+
+The purpose and utility of these commands (and their synonyms) is not only to
+draw a citation from the dataset for inclusion in the bibliography, but also to
+mark the place in the text where the citation is relevant. Normally, one might
+claim that this should be done through one of the forms of the \Cindex {cite} (or
+\Cindex {citation}) command, as all references appearing in the bibliography are
+to be cited at least once in the text. However, even if one does not disagree
+with this statement, one might still wish attach the citation to the reference in
+the text of a \Index {floating object} such as a table or a figure, thus
+establishing a proper order in the numbering since the explicit citation
+rendering might occur within the table or the figure caption that might get
+placed on a much later page. Consider the following schematic illustration:
+
+\cindex{nocite}
+\cindex{cite}
+
+\startTEX
+(see \nocite [MyReference]\in {table} [tab:mytable]).
+
+\startplacetable[reference=tab:mytable]
+    \unknown\ \cite[MyReference]
+\stopplacetable
+\stopTEX
+
+The citation rendering and the bibliographic list rendering are intimately
+coupled reciprocally and cannot be dissociated. This coupling can be through the
+reference number for example, but unnumbered reference lists also contain
+interacting hyperlinks. A failure to take into account this interdependence can
+lead to fundamental misunderstandings in use.
+
+\startaside
+Both the citation and the list must be rendered. For example, a common error
+would be to omit (or comment|-|out) the list rendering during the writing stage
+of a document. Such an error will cause the citations to fail to render properly.
+
+Whereas this might seem to be an unnecessary limitation, it results from a
+specific design choice and from the possibility of placing multiple renderings
+freely, anywhere in a document. It is preferable not to render citations at all
+than to render these citations possibly incorrectly.
+\stopaside

+\startsection[title=Combining citations]

+
+A single citation might refer to several sources, obtained through the use of a
+comma separated list of \Index{tag}s, for example: \getbuffer
+
+\cindex{cite}
+
+\typeTEXbuffer
+
+A comma separated list of three (or more) consecutive numbers will get collapsed
+or compressed into a range of numbers (if possible).
+
+\cindex {cite} The order in which the citation \Index {tag}s appear in the list
+may or may not be important, depending upon the citation variant and on the style
+specification. Consider the following examples:
+
+\startbuffer
+\cite[num]        [article,book]
+\cite[textnum]    [article,book]
+\cite[authoryear] [article,book]
+\cite[authoryears][article,book]
+\cite[short]      [article,book]
+\cite[author]     [article,book]
+\cite[year]       [article,book]
+\cite[title]      [article,book]
+\stopbuffer
+
+\typeTEXbuffer
+
+This gives:
+
+\cindex{cite}
+\startlines \getbuffer \stoplines
+
+Now we swap the order:
+
+\startbuffer
+\cite[num]        [book,article]
+\cite[textnum]    [book,article]
+\cite[authoryear] [book,article]
+\cite[authoryears][book,article]
+\cite[short]      [book,article]

+\cite[year]       [book,article]
+\cite[title]      [book,article]
+\stopbuffer
+
+\typeTEXbuffer
+
+and get:
+
+\startlines \getbuffer \stoplines
+
+Note that the numbered citation reference is always rendered in numerical order,
+where the numbers correspond to the order in which the entries appear in the
+bibliography list. This order depends on the \Index {sorting} of the list
+rendering (this sorting may be, in some styles, in the order in which the
+references are cited) and is controlled by the \TEXcode {[list]} \TEXcode
+{sorttype} parameter. In the \index {style+APA}APA style, presently active, the
+citations are always sorted according to author and year. Thus, \quotation
+{BookAuthorLastname} appears before \quotation {Last} in our example here,
+regardless of the order in which the references appear in the \Cindex {cite}
+command (i.e. either \TEXcode {\cite[article,book]} or \TEXcode
+{\cite[book,article]}).
+
+The user can control the state of sorting of the \cindex{cite}\TEXcode {cite}
+variants through the parameter \TEXcode {sorttype=normal}; other choices are
+\TEXcode {reverse} and \TEXcode {none}:

+\startsubsubject [title=Single list item containing multiple publication entries]
+
+Some bibliography styles admit the combination of several bibliographical sources

+multiple bibliographic entries into as single bibliography list item is more
+compact and this practice is often encountered in short \quote {letter}|-|type
+journal articles. (Note, however, that entries combined as such do not make any
+sense in an authoryear scheme such as \index {style+APA}APA.)
+
+One can combine \Index {tag}s using the addition operator symbol (\TEXcode {+}),
+best illustrated though an example:
+

+\cindex {removepunctuation}\TEXcode {separator={\removepunctuation;\space}}.
+
+Dataset entries that are combined cannot also appear apart (nor does this really
+make any logical sense). All of the following:
+
+\startbuffer

+
+will point to the combined reference (as they should). However, beware that
+attempting to include any of these references in a \emphasis {different} combined
+list item is undefined, meaning unsupported.
+
+Combining list entries is another instance showing that citations and the

+\stopbuffer
+
+\getbuffer
+
+obtained by using
+
+\cindex{placecitation}

+{citation}\TEXcode {[entry][tag]} (that was seen earlier).
+
+\showsetup[placecitation]
+
+As for other citation reference, this will fail if a bibliography list rendering
+is not placed somewhere in the document so let's do that here:
+
+\startbuffer
+\placebtxrendering[tugboat][criterium=section]
+\stopbuffer
+
+\cindex{placebtxrendering}
+
+\typeTEXbuffer \getbuffer
+
+Whereas this might seem redundant above (placing the citation entry as well as
+its list rendering), this will only exceptionally be the case (as in this highly
+artificial example of this manual); Indeed, all cited work (such as \cite
+[textnum] [tugboat::Mahajan:TB31-1-88], above) will logically always be placed in
+a list of references.
+
+The placement of a single citation brings to light a subtle point: The \TEXcode
+{specification} that is used by citations is that set in the root namespace
+(through \Cindex {setupbtx}\TEXcode {[specification=apa]} or possibly through
+\Cindex {usebtxdefinitions}\TEXcode {[apa]}. This is \emphasis {not} necessarily
+the same as that of the rendering (if a different rendering specification is
+declared). Note that the named rendering used above (\TEXcode {[tugboat]}) was
+not declared a child of the rendering named \TEXcode {[aps]}, though the \TEXcode
+{specification=apa} is active. Thus, the style of the citations can be made to
+differ from the style of their bibliography list, as here, but this is not really
+a very good practice.
+
+\stopsection
+
+\startsection[title=Placing citations as footnotes]
+
+A \Cindex {placecitation} command can occur inside a footnote or other \Index

+yet.
+
+% bibliographies as endnotes intercalated with footnotes...
+
+\stopsection
+
+\startsection[title=Searching]
+
+Finding the right \Index {tag} in a database can be a pain. In particular,
+datasets having their origin in multiple source files may contain conflicting
+\Index {tag}s, though duplicate \Index {tag}s get suffixed automatically so this
+should not be a real problem.
+
+On the other hand, asking for a \Index {wildcard} also makes no sense.
+\startfootnote Note that \cindex {nocite}\TEXcode {\nocite{*}} is a valid
+\LATEX/\BIBTEX\ practice that is used to include all entries of a \Tindex {.bib}
+file in the final bibliography. This result can be obtained in \CONTEXT\ through
+the \TEXcode {method=dataset} list rendering parameter. Alternately, one can use
+the syntax \cindex {cite}\TEXcode {\cite[match(*:*)]} which is a shorthand to
+match all values of all fields. \stopfootnote Nevertheless, we provide a powerful
+mechanism for matching a query. Keep in mind that a \Index {tag} is used as a
+quick look|-|up in a hashed table whereas a search will look through the entire
+dataset. If processing speed is critical, one should use the cite \Index {tag}
+lookup; in practice, even on a big book project employing a very large dataset,
+the search is not a penalty.
+
+Let's look in more detail at the \Cindex {cite} command. In order to distinguish
+efficiently between a normal reference and a more clever one, we use the \TEXcode
+{match()} function:
+
+\tindex{::}
+\startTEX
+match(query)
+dataset::match(query)
+dataset :: match ( query )
+\stopTEX
+
+The handler is rather tolerant for spaces (as well as capitalization) which is
+handy if you have long queries that wrap around in the source code. Of course the
+\tindex {::}\TEXcode {dataset::} prefix is optional in which case the current
+dataset is taken. Such match queries can be mixed in a multiple reference
+citation indifferently with hashed cite \Index {tag}s so the system is really
+flexible.
+
+\blank
+
+To demonstrate the use a search query, we load a small bibliographic database:
+
+\startbuffer
+\usebtxdataset[boekplan][boekplan.bib]
+\stopbuffer
+
+\cindex{usebtxdataset}
+
+\typeTEXbuffer
+
+\getbuffer
+
+We could switch to this base using:
+
+\cindex{setupbtx}
+\startTEX
+\setupbtx[dataset=boekplan]
+\stopTEX
+
+but instead we shall use a prefix as seen previously. Consider the following:
+
+\startbuffer
+everything that you might want to know about layouts
+\cite[boekplan::match(author:Egger)]
+\stopbuffer
+
+\cindex{cite}
+\tindex{::}
+
+\typeTEXbuffer
+
+We will get: \quotation {\inlinebuffer}. Of course this assumes that we also
+typeset a list of references somewhere in our document, so let's do that here:
+
+\startbuffer
+\definebtxrendering[boekplan][apa][dataset=boekplan,group=examples]
+\placebtxrendering [boekplan][criterium=chapter]

+\stopbuffer
+
+\cindex{cite}
+\tindex{::}
+
+\typeTEXbuffer \getbuffer
+
+Notice that no match is found in the \quote {current} dataset (\TEXcode {example}).
+
+A query eventually becomes a \LUA\ expression so you can use helpers to achieve
+your goal. As a convenience there are some shortcuts to access fields. The
+following examples demonstrate this:
+
+\startbuffer
+\cite
+  [authoryears]
+  [boekplan::match(author:hagen and year:2010-2011)]\\
+\cite
+  [authoryears]

+\stopbuffer
+
+\cindex{cite}
+\tindex{::}
+
+\typeTEXbuffer \getbuffer
+
+This demonstrates further the interest in converting classical \TEX\ accent
+sequences into proper \UTF\ characters. The citations found above \bold{must}
+correspond to some bibliography list entries, so we will place this list here:
+
+\startbuffer
+\placebtxrendering [tugboat][criterium=section]

+\stopbuffer
+
+\cindex{cite}

+finds \inlinebuffer. As the match compares the entire author string, and not
+just each author, it also finds [Hag]en & Br[aslau] as well as [Ho]ekwater[ &
+Hagen].
+
+% To Hans: It is curious that match(author:e*r) finds [Hag]en and Br[aslau].
+% To Alan: We match the whole (original) string.
+%
+% Response: Yes, but this is not what one might naively expect.
+% It would be useful to match author by author, rather than the entire author
+% string, at least that is how one might want to use it. Oh well...
+% the mechanism is predictable and the above example explicitly explains this
+% point. Would it be easy to add match(lastname:h*), for example? I suppose that
+% this would have to yield hits in ALL author-type fields (author, editor, ...).
+
+Note also that the order of the match criteria is not significant.
+
+\startaside
+The search mechanism is very powerful. However, a \bold {major \Index{pitfall}}
+or risk comes from the possibility to easily under|-|specify the match criteria.
+For example, \TEXcode {match(author:Hagen and author:Hoekwater)} will find \cite
+[title] [boekplan::match(title:Fonts)], but it will also find \cite [title]
+[boekplan::match(title:Layouts)]; Nor would adding the criterium \TEXcode {and
+year:2011} be of any help. The solution is
+
+\startbuffer
+\cite
+  [authoryear]
+  [boekplan::match(author:Hagen and author:Hoekwater and title:fonts)]
+\stopbuffer
+
+\cindex{cite}
+\tindex{::}

+\typeTEXbuffer \getbuffer
+
+Note that using \TEXcode {match(title:fonts)} alone would also work, that is
+until another reference work containing the word \quote {fonts} in its title gets
+added to the dataset! \startfootnote Multiple hits would have occurred in the
+examples above containing \TEXcode {title:lua} had only one dataset been used in
+the typesetting of the present manual. \stopfootnote Thus, whereas it might
+appear that the match mechanism be a more robust way of identifying dataset
+entries then short cite \Index {tag}s, incomplete search queries might return
+unwanted, excess matches.
+
+It is quite common in real bibliography databases for some author or authors to
+appear in many different references published in the same year, perhaps buried in
+a longer list of authors, so some care has to be taken to uniquely identify the
+desired work. Of course, this feature can also be a good shorthand as well to
+select several different matching works when that is the desired result.

+first occurrence in the text where the entry is cited (which is the same as the
+first page indexed).
+
+Some styles, such as \index {style+APA}\TEXcode {apa}, will have other \Index
+{hyperlink}s. The author list including the year will be active just like the
+numbers above (an \TEXcode {authoryear} list is usually not numbered).
+Furthermore, any doi or url that is included in the entry will be a \Index
+{hyperlink} to the external resource. Finally, all titles will contain \Index
+{hyperlink}s to the local downloaded file of the cited work if this exists and
+was specified (using the data field \TEXcode {file={},}).
+
+In addition to the index of pages of citations in the text associated with each
+entry in the bibliography list, one has the possibility of adding bibliography
+items to any standard index list. This can be illustrated through the creation of
+a list of authors or names:
+
+\startbuffer
+\defineregister
+  [indexofauthors]
+
+\definebtxregister
+  [authors]
+  [field=author,
+   register=indexofauthors,
+   method=always,
+   dataset=default,
+   alternative=invertedshort]
+\stopbuffer
+
+\cindex{defineregister}
+\cindex{definebtxregister}
+
+\typeTEXbuffer
+
+placed in the preamble of the document and to be followed later, typically
+towards the end of the document, by
+
+\cindex{placeregister}
+
+\startTEX
+\startchapter[title=Index of Names]
+    \placeregister[indexofauthors][compress=yes]
+\stopchapter
+\stopTEX
+
+as can be see in the present manual on \at {page} [ch:indexofauthors].
+
+\cindex   {definebtxregister}
+\showsetup[definebtxregister]
+
+\cindex   {setupbtxregister}
+\showsetup[setupbtxregister]
+
+Any field can be indexed, as desired, for example \TEXcode {field=title}. One
+particularly useful field is \TEXcode {keywords={}}: a semi|-|colon separated
+list of keywords will be split into individual index entries for each cited work.
+
+The handling of fields to be interpreted as names (as in \TEXcode {author}) or as
+keywords (split into fields separated by semi|-|colons), etc. depends on the
+specification and is declared in a lua file associated with the specification
+definition file. This will be described in the next chapter.
+
+\stopsection
+
+\startsection [title=Summary and explanation of the \TEXcode {\cite} mechanism]
+
+As the list of cited references is being built in memory, each used dataset entry
+is flagged. As the list gets placed, either partially or fully, eventual conflits
+in \TEXcode {short} and in \TEXcode {authoryear} tags are resolved through an
+assignment of suffixes. These are then fed|-|back to the citation references.
+
+A dataset can have multiple renderings and multiple datasets and renderings can
+be grouped. The many citation variants can be freely used together and this may
+or may not make coherent sense. For example, an \TEXcode {authoryear} sorted list
+is assigned numbers that are available for use as numbered citation references,
+but these numbers will follow the order of the list and not the order of
+citations. Conversely, a list that is sorted in the order of citations will still
+have \TEXcode {authoryear} and \TEXcode {short} citation tags, but these will be
+of less use for the reader in this case than the \TEXcode {authornum} variant.
+With such flexibility comes complication.

+
+\startsection[title=Introduction]
+
+The rendering of citations and bibliography lists is highly configurable and
+custom rendering schemes can be added. The details can get quite complicated so
+we will begin with a description of how citation variations can be used in the
+running text, followed by a description on how to control the rending of the
+associated bibliography list.
+
+\startaside
+Loading the specification file defines a \Index {namespace}, say \TEXcode {apa},
+containing subspaces \TEXcode {apa:list} and \TEXcode {apa:cite} as well as
+variants, for example \TEXcode {apa:cite:authoryear}, allowing \emphasis
+{parameters} to be tuned independently for each form. This insures independence
+but can get somewhat confusing. Most users will not encounter any problems as all
+of this setup work is taken care of in the specification file; only those needing
+to fine|-|tune specific settings need to better understand the underlying
+mechanism.
+
+The rendering of the variants can be adjusted through \Cindex {setupbtx} in the
+appropriate \Index {namespace}, for example modifying (or suppressing)
+parenthesis or activating or deactivating interaction \Index {hyperlink}s. Beyond
+the settings of parameters in the appropriate \Index {namespace},
+\emphasis{setups} are used to perform the actual renderings of citations as well
+as of lists. One must be aware of \Index {namespace} \Index {isolation} and
+\Index {inheritance} as well as fall|-|back when attempting to make changes.
+
+When small modifications on one of the pre|-|defined specifications are desired,
+we suggest loading the specification and then adjusting certain parameters and
+overloading the appropriate setups. Eventually, a new specification might be
+necessary.
+\stopaside
+
+A common setup will enable or disable interaction:
+
+\startbuffer
+\setupbtx [interaction=start]
+\stopbuffer
+
+\cindex{setupbtx}
+
+\typeTEXbuffer
+
+Notice that this is applied to the root \Index {namespace}.
+
+Other root|-|\Index {namespace} parameters that have been used are \TEXcode
+{specification}, \TEXcode {dataset} and \TEXcode {numbering}.
+
+Associated with \TEXcode {specification} is an additional parameter \TEXcode
+{default=} that defines a fall|-|back specification to be used to complete a
+derived specification. \startfootnote For example, a variant on a specification
+can be defined by only addressing specific differences, for example \index
+{style+RMP}\TEXcode {specification=rmp} would be associated with \index
+{style+APS}\TEXcode {default=aps}, as this describes a style used by the journal:
+The Review of Modern Physics, mostly based on the style of the American Physical
+Society. \stopfootnote
+
+Further \quote {low|-|level} formatting parameters, mostly dealing with the
+formatting of names, are also defined by default in the root namespace. These are
+listed in \in {table} [tab:setupbtx]. Some might eventually be redefined by the
+specification in other namespaces, and may with good reason differ by context:
+between the \TEXcode {[cite]} and \TEXcode {[list]} namespaces, for example.
+
+In order to insure the independence of specifications, each one defines its own
+root namespace, for example \TEXcode {[default]}, \TEXcode {[apa]} or \TEXcode
+{[aps]}, inheriting its settings from root, upon which are built the other
+namespaces.

+
+The next step in the customization of citation variants is through the overlaying
+of setups that handle the actual rendering of the citation. These rarely will
+need to be changed as most tuning can be done through the adjustment of
+parameters such as those given above. \startfootnote An exception is for special
+features, such as in the \index {style+APA}\TEXcode {apa} specification where a
+missing date is replaced by the notation \quotation {n..d.}. \stopfootnote
+
+It is to be pointed|-|out that original citation variants can be easily added. As
+an example, imagine that one might like to access the field \TEXcode {abstract}
+that is normally not rendered (like many other unused dataset fields). One would
+start by defining a parameter \Index {namespace} inheriting from the \TEXcode
+{cite} \Index {namespace}, followed by a simple setup (remember that the \TEXcode
+{apa} specification is currently active):
+
+\startbuffer
+\definebtx[apa:cite:abstract][apa:cite]
+\startsetups btx:apa:cite:abstract
+    \btxcitereference
+    \btxflush{abstract}
+\stopsetups
+
+\startparagraph [style=slanted]
+\cite[abstract][boekplan::Hagen2010metafun]
+\stopparagraph
+\stopbuffer

+\cindex{definebtx}
+\cindex{btxcitereference}
+\cindex{btxflush}
+\cindex{cite}
+\cindex{startsetups}
+\cindex{stopsetups}
+\tindex{::}
+
+\typeTEXbuffer
+
+\getbuffer
+
+If no special manipulation is known, the field with the same name (if found) will
+be simply flushed. This will only work, however, if the field is identified as
+either required or optional, that is not flagged as ignored in \in {table}
+[tab:fields] (see also \in {Appendix} [ch:datasetfields]). For the sake of the
+present manual, the field \BTXcode{abstract} has been defined as optional for the
+\BTXcode{book} entry in the specification's lua file.
+
+But don't expect too much support for such low|-|level rendering control.
+
+\stopsubsubject
+
+\stopsection
+
+\startsection[title=Custom list renderings,reference=sec:list]
+
+The rendering of lists is much more flexible and configurable than the rendering
+of citation markers. This is because the nature of data to be rendered requires
+many tools and helpers to deal with all of the eventual contingencies inherent in
+describing bibliographical references.
+
+The same \quote {low|-|level} formatting parameters used for citations also apply
+for \TEXcode {list} \Index {namespace}s, although their settings may differ from
+those of the citations. Consider the \index {style+APA}\TEXcode {apa} style that
+specifies the use of \tindex {others} \quotation {et al.} in citations but
+\quotation {\textellipsis} in the bibliography list, \quotation {and} in
+citations but \quotation {\textampersand} in lists, last names only in \TEXcode
+{authoryear} citations, etc.
+
+\startsubsubject[title=Bibliographies as lists]
+
+At another level of detail, the bibliography list is rendered in a standard
+\CONTEXT\ list environment that can be setup using the command \Cindex
+{setupbtxlist} (which is only \Cindex {setuplist} working in the protected
+bibliography environment: \TEXcode {btx}). The root settings, appropriate for a
+numbered bibliography list, are:
+
+\cindex{setuplist}
+
+\startTEX
+\setuplist
+  [btx]
+  [prefixstopper=:,
+   state=start,
+   alternative=a,
+   before=\blank,
+   after=\blank]
+\stopTEX
+
+whereas an unnumbered, author|-|year sorted list might have:
+
+\cindex{setupbtxlist}
+
+\startTEX
+\setupbtxlist
+  [apa]
+  [alternative=paragraph,
+   margin=3\emwidth]
+\stopTEX
+
+as already seen in \in {Chapter} [ch:renderings]. The above demonstrate that
+\cindex {setupbtxlist}\TEXcode {\setupbtxlist[name]} is just a synonym for
+\cindex {setuplist}\TEXcode {\setuplist[btx:name]}.
+
+\cindex   {setupbtxlist}
+\showsetup[setupbtxlist]
+
+\cindex   {setuplist}
+\showsetup[setuplist] % too big for the page!
+
+Each specification will have its own list \Index {namespace} (\TEXcode
+{btx:specification}) that inherits from the root \TEXcode {btx} \Index
+{namespace}. This model of inheritance holds true for the citation and list
+details as described earlier.
+
+\stopsubsubject
+
+\startsubsubject[title=Setups]
+
+The layout of the information presented in the list is entirely controlled
+through setups, with the help of some underlying \LUA\ code organizing the data
+stored in the dataset. These setups rely on further setups as well as some
+convenient helpers or defined special commands. To understand this, consider as
+an illustration the setups defined for the \TEXcode {default} specification
+(taken from the source file \type {publ-imp-default.mkvi}):
+
+\cindex{startsetups}
+\cindex{stopsetups}
+\cindex{texdefinition}

+\stopsetups
+\stopTEX
+
+This specification could be extended to handle publication categories other than
+\TEXcode {book} and \TEXcode {article} simply by defining an additional setup,
+\emphasis {almost} (see the following).
+
+\stopsubsubject
+
+\startsubsubject[title=\LUA\ tables]
+
+The qualification above is to bring attention to an important \LUA\ component
+that is defined in a companion source file: \TEXcode {publ-imp-default.lua}. This
+file defines a hierarchical \LUA\ table containing an element \TEXcode
+{categories} that itself contains the entries \TEXcode {book}, \TEXcode
+{article}, etc. The entries for each \Index {category} themselves contain the
+entries \index {field+required}\TEXcode {required} and \index
+{field+optional}\TEXcode {optional} listing the dataset fields that are to be
+used. Any field that is not declared either \index {field+required}required or
+\index {field+optional}optional will be \index {field+ignored}\emphasis
+{ignored}. \startfootnote The difference between \index {field+required}\quote
+{required} and \index {field+optional}\quote {optional} is only a question of
+diagnostics as described in the Appendices. Their functional meaning is rather
+\quote {handled} in contrast to \index {field+ignored}\quote {ignored}.
+\stopfootnote Note that if a category is \emphasis {not} declared in this \LUA\
+table, than \emphasis {all} of its fields will be considered \index
+{field+optional}\quote {optional}. Thus, ignoring this level of control and
+simply defining additional setups might be sufficient for most use.
+
+The advantage of the \LUA\ table is a great simplification of the logic of the
+helper setups. Fields that might be irrelevant for one category yet used in
+another can be tested; if the field is to be \index {field+ignored}\quote
+{ignored}, than a fetch will return nothing. Indeed, the above two setups could
+be replaced by a single setup as \TEXcode {journal} is irrelevant and thus
+ignored for the \Index {category} \TEXcode {book} but not for the \Index
+{category} \TEXcode {journal}. However, an oversimplification such as just
+described would be rather confusing and would not extend well to a more complete
+specification (such as \index {style+APA}\TEXcode {apa}) handling many different
+categories.
+
+Note, as well, that fields \index {field+ignored}\quote {ignored} for certain
+\index {category}categories in the bibliography list will also be ignored in
+citations. For example, choosing to ignore \TEXcode {title} in some \Index
+{category}, say \TEXcode {article}, will cause \TEXcode {\cite[title]} to fail
+(return nothing) when referring to an entry of that category. In the example
+shown in \in {section} [sec:customcite], the abstract field would not return
+anything if it did not appear in the \LUA\ table.
+
+This \LUA\ table also defines (as \index {type}\quote {types}, outside of \index
+{category}\quote {categories}) what fields are to be interpreted as names, what
+fields are to eventually be interpreted as a number or range of numbers, and what
+fields are to be interpreted specially as a (semi|-|colon) separated list (for
+example, \TEXcode {keywords}).
+
+A more subtle feature of the \LUA\ level is the notion of \index {set}\quote
+{sets}. Related fields can be grouped into sets, for example.
+
+\startLUA
+book = {
+    sets = {
+        author     = { "author", "editor", },
+        editionset = { "edition", "volume", "number" },
+    },
+},
+\stopLUA
+
+A fetch of the set \text {author} (i.e. \cindex {btxflush}\TEXcode
+{\btxflush{author}}, to be described below) will return the \text {author} field
+if this is present, otherwise it will return the \TEXcode {editor} field, for an
+edited book, for example. Testing for the presence of a set in a data entry is
+equivalent to a logical \emphasis{or} in testing for the presence of each element
+of the set. This mechanism can appear confusing yet it has served to greatly
+simplify the logic of the various setups. \startfootnote Sometimes a \Index {set}
+will be defined using the same name as its first element, sometimes it can be
+given a unique name (typically ending in \quote {set}). \stopfootnote
+
+The \TEXcode {author} set is a bit special given its use in the \TEXcode
+{authoryear(s)}, \TEXcode {authornum}, and \TEXcode {short} citation variants.
+This \Index {set} determines what fields are to enter into the citation \Index
+{tag}s, a generalization of the notion of author. For example, in the \index
+{style+APA}APA style, this set would include the author, editor, or title fields
+or an article and the author, editor, publisher, or title fields for a book and

+
+Fetching data from the dataset is performed using the command encountered above:
+\TEXcode {\btxflush}. If the field (or no elements of the set) is not found, then
+this command will return nothing.
+
+\cindex   {btxflush}
+\showsetup[btxflush]
+
+Alternately, one might need to explicitly test for the presence or absence of the
+field, in order to conditionally include punctuation or not to trigger
+separators, for example. Three test macros have been defined:
+
+\startplacetable [title=Conditional macros]
+\cindex{btxdoifelse}
+\cindex{btxdoif}
+\cindex{btxdoifnot}
+\startTEX
+\btxdoifelse{fieldname}{action when found}{action when not found}
+\btxdoif    {fieldname}{action when found}
+\btxdoifnot {fieldname}                   {action when not found}
+\stopTEX
+\stopplacetable
+
+In many cases, the readability can be improved by using further setups, for
+instance:
+
+\cindex{btxdoifelse}
+\cindex{fastsetup}
+
+\startTEX
+\btxdoifelse {author} {
+    \fastsetup{btx:apa:author:yes}
+} {
+    \fastsetup{btx:apa:author:nop}
+}
+\stopTEX
+
+Note that the choice between using setups (defined through \Cindex {startsetups}
+\unknown\ \Cindex {stopsetups} and recalled through \Cindex {fastsetup}) versus
+textdefinitions without arguments (defined through \Cindex {starttexdefinition}
+\unknown\ \Cindex {stoptexdefinition} and recalled through \Cindex
+{texdefinition}) is a question of taste and opportunity. One should keep in mind
+not get carried away abusing setups and texdefinitions for simple code fragments
+that are to be used uniquely.
+
+An extra conditional is available for testing interactivity:
+
+\cindex{btxdoifelseinteraction}
+
+\startTEX
+\btxdoifelseinteraction{action when true}{action when false}
+\stopTEX
+
+There is also a conditional \Cindex {btxinteractive} which is more efficient,
+although in practice efficiency is not so important here.
+
+\blank
+
+In addition to \Index {set}s, there are derived or special fields such as
+\TEXcode {num} (for the reference number), \TEXcode {suffix} (to be appended in
+some cases to \TEXcode {year}), \TEXcode {short} (for names), etc. These all can
+be retrieved using \Cindex {btxflush}. Sometimes one might want to force access
+to a particular data field (such as \TEXcode {author}) rather than eventually an
+element of a \Index {set} having the same name. There are three basic commands to
+flush data and a few others to flush associated information:
+
+\startplacetable [title=Field access macros]
+\starttabulate[|l|l|]
+\NC \Cindex{btxflush}     \NC fetch a derived or explicit field \NC \NR
+\NC \Cindex{btxdetail}    \NC fetch a derived field (e.g.\ \TEXcode {short}) \NC \NR

+\NC \Cindex{btxfoundtype} \NC fetch the field type of a set (or field) \NC \NR
+\stoptabulate
+\stopplacetable
+
+A few helpers are provided to inject symbols but also take care of leading and
+trailing spaces: \startfootnote These make use of the \CONTEXT\ command \Cindex
+{removeunwantedspaces}. There is also a \quote {secret} command \TEXcode
+{\removepunctuation} that can be quite useful, but also lead to undesired
+consequences when wielded blindly! \stopfootnote

+
+Normally you can use \TEXcode {\btxfield} or \TEXcode {\btxflush} as derived
+fields just like analyzed author fields are flushed in a special way. There is
+experimental support for so called manipulators. You can for instance say this:
+
+\starttyping
+\btxflush{lowercase->title}
+\stoptyping
+
+A sequence of manipulators is applied to fetched field, where a sequence is one
+or more manipulators:
+
+\starttyping
+\btxflush{stripperiod->uppercase->title}
+\stoptyping
+
+Some actions are recognized (built|-|in) but you can also use actions from other
+namespaces, like in:
+
+\starttyping
+\btxflush{converters.Word -> title}
+\stoptyping
+
+Watch how we can use spaces around the \TEXcode {->} which is nicer for wrapped
+around usage. Eventually, we might put some more function in the default
+namespace.
+
+So, the previous example setup can be rewritten as:
+
+\starttyping
+\btxdoif {title} {
+   \bold{\btxfield{title}}
+   \btxcomma
+}
+\stoptyping
+
+There is a special command for rendering a (combination) of authors:
+
+\starttyping
+\btxflushauthor{author}
+\btxflushauthor{editor}
+\btxflushauthor[inverted]{editor}
+\stoptyping
+
+Instead of the last one you can also use:
+
+\starttyping
+\btxflushauthorinverted{editor}
+\stoptyping
+
+You can use a (configurable) default or pass directives: Valid directives are
+
+\starttabulate
+\NC \bf conversion          \NC \bf rendering        \NC \NR
+\HL
+\NC \TEXcode{inverted}      \NC the Frog jr, Kermit  \NC \NR
+\NC \TEXcode{invertedshort} \NC the Frog jr, K       \NC \NR
+\NC \TEXcode{normal}        \NC Kermit, the Frog, jr \NC \NR
+\NC \TEXcode{normalshort}   \NC K, the Frog, jr      \NC \NR
+\stoptabulate
+
+The list itself is not a list in the sense of a regular \CONTEXT\ structure
+related list. We do use the list mechanism to keep track of used entries but that
+is mostly because we can then reuse filtering mechanisms. The actual rendering of
+a reference and entry runs on top of so called constructions (other examples of
+constructions are descriptions, enumerations and notes).
+
+\showsetup[setupbtxlist]
+
+You need to be aware what command is used to achieve the desired result. For
+instance, in order to put parentheses around a number reference you say:
+
+\starttyping
+\setupbtxlistvariant
+ [num]
+ [left=(,
+  right=)]
+\stoptyping
+
+If you want automated width calculations, the following does the trick:
+
+\starttyping
+\setupbtxrendering
+ [default]
+ [width=auto]
+\stoptyping
+
+but if you want to control it yourself you say something:
+
+\starttyping
+\setupbtxrendering
+ [width=none]
+
+\setupbtxlist
+ [default]
+ [width=3cm,
+  distance=\emwidth,
+  color=red,
+  headcolor=blue,
+  headalign=flushright]
+\stoptyping
+
+In most cases the defaults will work out fine.
+
+Normally the references are numbered using one counter for the whole document. If
+you want each list to have its own number, then you can set the \TEXcode
+{continue} parameter:
+
+\starttyping
+\setupbtxrendering[continue=no]
+\stoptyping
+
+In a similar fashion you can influence if references are included only once of in
+each list:

+\startchapter[title=The database]
+
+The bibliography subsystem uses a database (or a set of databases) to construct a
+list of citations to be used in a scholarly work. However, it will be shown later
+that the database system can be used (and abused) to many ends having little or
+nothing at all to do with citations and bibliographies. Nevertheless, at first we
+shall remain focused on the use of bibliography databases.
+
+The data to be used must have a source and a structure. In the next sections we
+describe the possible input.
+
+\startsection[title=\BibTeX]
+
+The \BIBTEX\ format is rather popular in the \TEX\ community and even with its
+shortcomings it will stay around for a while. Many publication websites can
+export and many tools are available to work with this database format. It is
+rather simple and looks a bit like \index [LUA table] {\LUA\ table}\LUA\ tables.
+Indeed, it is said that the \BIBTEX\ format was one of the inspirations for the
+constructor syntax in \LUA\ \cite [alternative=num,
+righttext={\btxcomma Chapter\nbsp 12.}] [default::Ierusalimschy2006].
+
+Unfortunately the content can be (and usually is) polluted with
+non|-|standardized \TEX\ commands which complicates pre- or post|-|processing
+outside \TEX. In that sense a \BIBTEX\ database is often not coded neutrally.
+Some limitations, like the use of commands to encode accented characters root in
+the \ASCII\ world and can be bypassed by using \index [UTF] {\UTF}\UTF\ instead
+(as handled somewhat in \LATEX\ through extensions such as \Tindex {bibtex8}).
+
+The normal way to deal with a bibliography is to refer to entries using a unique
+\Index {tag} or key. When a text containing a list of entries is typeset, this
+reference can be used for linking purposes. The list can be processed and sorted
+using the \Tindex {bibtex} program that converts the database into something more
+\TEX\ friendly (a \Tindex {.bbl} file).
+
+In \CONTEXT\ we no longer use the (external) \goto {\Tindex {bibtex} program}
+[url(https://www.ctan.org/pkg/bibtex)] at all: we simply parse the database files
+in \LUA\ and deal with the necessary manipulations directly in \CONTEXT. One or
+more such databases can be used and combined with additional entries defined
+within the document. We can have several such datasets active at the same time.
+
+\startaside
+\emphasis {On the name \Tindex {btx}:} many of the \CONTEXT\ commands that will be
+used in the following contain the label \TEXcode {btx} in their name. This
+identifier was retained despite the fact that \CONTEXT\ \MKIV\ is now completely
+independent of \BIBTEX; it reflects the role still played by \BIBTEX\ data as a
+preferred source format and serves as a handy, unique identifier, both internally
+in the programming as well as for the user. This three|-|letter label is
+systematically used in commands that otherwise attempt to avoid cryptic|-|styled
+names.
+\stopaside
+
+A \BIBTEX\ file entry looks like this:
+
+\startBTX
+@Article {sometag,
+    author  = "An Author and Another One",
+    title   = "A hopefully meaningful title",
+    journal = maps,
+    volume  = "25",
+    number  = "2",
+    pages   = "5--9",
+    month   = mar,
+    year    = "2013",
+    ISSN    = "1234-5678",
+}
+\stopBTX
+
+Entries are of the form: \index {category}\BTXcode {@category{...}}
+
+Anything outside of a valid \BTXcode {@category{...}} construction is ignored and
+is taken to be a comment. Within an entry, there are to be no comments but one
+can prefix field names, for example, to have them ignored.
+
+There is a special entry type named \index {@comment}\BTXcode {@comment{...}}.
+The main use of such an entry type is to comment a large part of the bibliography
+easily, since anything outside an entry is already a comment, and commenting out
+one entry may be achieved by just removing its initial~\BTXcode {@}. — The \index
+{@comment}\BTXcode {@comment{...}} entry is perhaps of some use, although this is
+not very elegant! As one can input multiple bibliography data files, as will be
+seen below, it is much better practice to split datafiles for optional loading.
+
+Many \BIBTEX\ data management tools such as \Tindex {jabref} (see below) will
+ignore and then throw|-|away all such handily|-|crafted comments and data entries
+turned into comments. So one must beware!
+
+The field names are all cast to lowercase so capitalization is irrelevant;
+Spacing is not important and should be used advantageously for readability. The
+leading \Index {tag} (\BTXcode {sometag} in the example above) cannot contain
+spaces and \emphasis {must} be followed by a comma.
+
+The entry \Index {tag} (\BTXcode {@category{sometag,...}}) is not to be confused
+with the optional field \BTXcode {key=sortkey,} that may also be present.
+
+Normally a value is given between quotes (or curly brackets) but single words are
+also valid (as there is no real benefit in not using quotes or curly brackets, we
+advise to always use them, contrary to our example above). The order of the
+fields in an entry is inconsequential and there can be many more fields than
+those shown above. Instead of string values one can also use predefined
+shortcuts. The title for example might quite often contain \TEX\ macros, and some
+fields, like \BTXcode {pages} have funny characters such as the endash (typically
+entered as \BTXcode {--}) so we have a mixture of data and typesetting
+directives. Furthermore, if you are covering non||English references, you often
+need characters that are not in the \ASCII\ subset. Note that \CONTEXT\ is quite
+happy with \UTF, but if your database file uses old|-|fashioned \TEX\ accent
+combinations then these will be internally converted automatically to \UTF.
+
+Commands (macros) found in a database file are converted to an indirect call,
+which is quite robust. The use of commands in the database file will be described
+in \in {section} [sec:Commands].
+
+The \Tindex {author} (and \Tindex {editor}) fields are parsed separating multiple
+authors identified by the conjunction \quote {and}. Each name is assumed to be in
+the form:
+
+\definetyping
+  [NameSyntax]
+  [margin=1em]
+
+\startNameSyntax
+Firstname(s) Lastname
+\stopNameSyntax
+
+\seeindex {vons} {particule}
+
+where \type {Lastname} is a single word but may include an optional (nobility)
+\Index {particule}: lower|-|case word(s) such as \quotation {von}, \quotation
+{de}, \quotation {de la}, etc.) \emphasis {unless} specifically in the two- or
+three|-|token form:
+
+\index {suffix}
+
+\startNameSyntax
+Lastname(s), Firstname(s)
+Lastnames(s), Suffix(es), Firstname(s)
+\stopNameSyntax
+
+separated explicitly using comma(s) thus allowing multi|-|word \type {Lastnames}.
+
+\startaside
+An \BTXcode {author} field is sometimes abused in traditional \BIBTEX\ usage to
+hold not a name but rather an entity. Other fields, such as \BTXcode
+{organization} or \BTXcode {collaboration}, for example, should be used in such
+cases.
+\stopaside
+
+\BIBTEX\ also (obscurely) supports the syntax:
+
+\seeindex {juniors}{suffix}
+\index {suffix}
+
+\startNameSyntax
+Firstname(s) \{Lastname(s), Suffix(es)\}
+\stopNameSyntax
+
+we may (or may not) support this in the future, so don't use this!
+
+We extend \BIBTEX\ by optionally parsing each name in terms of four or five
+tokens:
+
+\index {particule} \index {suffix} \index {initial}
+
+\startNameSyntax
+Particule(s), Lastname(s), Suffix(es), Firstname(s)
+Particule(s), Lastname(s), Suffix(es), Firstname(s), Initial(s)
+\stopNameSyntax
+
+in order to allow a free form for the particules, irrespective of capitalization,
+thus avoiding the need to resort to any sort of \TEX\ trickery \cite [num]
+[default::Patashnik1988,Markey2009]. In fact, an optional sixth token is parsed
+whose meaning is presently reserved for future directives describing how the name
+is to be interpreted:
+
+\index {particule} \index {suffix} \index {initial}
+
+\startNameSyntax
+Particule(s), Lastname(s), Suffix(es), Firstname(s), Initial(s), directives
+\stopNameSyntax
+
+\BIBTEX\ additionally accepts the special token \Tindex {others} to be used
+(sparingly) to indicate an incomplete author list. Note that most style
+specifications will handle the truncation of long author lists in a systematic
+fashion. The \index [others] {\tt and others}\BTXcode {and others} construction
+finds its use when the complete author list is not well known or ill|-|defined.
+
+Sometimes, or even often, the database might contain variants of an author's
+name that we would like to identify as a single, unique author. Indeed, certain
+bibliographic styles (as will be seen later) as well as an index of authors, for
+example, will depend on this identification. A command \Cindex {btxremapauthor}
+allows establishing this identity:
+
+\startbuffer
+\btxremapauthor [Donald Knuth] [Donald E. Knuth]
+\btxremapauthor [Don Knuth]    [Donald E. Knuth]
+\stopbuffer
+\getbuffer
+
+\cindex {btxremapauthor}
+\typebuffer [option=TEX]
+
+Fields other than \Tindex {author} and \Tindex {editor}, for example \Tindex
+{artist} or \Tindex {director} if one desires, can be declared to be of type
+\quote {author} and thus interpreted as names, but this is a subject for
+specialists.
+
+The \BTXcode {keywords} field can also be split into tokens separated by
+semicolons (keyword; keyword; \unknown). This can be useful, as will be seen
+later, in the creation of keyword indexes, for example.
+
+Other string values such as \BTXcode {title} are kept literally (except for an
+internal automatic conversion to \UTF\ of certain \TEX\ strings such as accent
+combinations, endash, quotations, etc.). Note that the bibliography rendering
+style (see below) might specify a capitalization of the title (using the
+\CONTEXT\ commands \TEXcode {\Word} or \TEXcode {\Words}, for example).
+Capitalized Names and acronyms are respected removing a need for the \BIBTEX\
+practice of \quote {protecting} such words or letters with surrounding curly
+brackets (which here are simply stripped off). (Furthermore, since \CONTEXT\ uses
+\UTF, it does not suffer from all of the complicated \Index {sorting} issues that
+plague \BIBTEX|/|\LATEX.) As some styles might not specify the capitalization of
+words in the title whereas other styles might, it is recommended that strings be
+written in lower case except where upper case is explicitly required so as to be
+compatible with all such capitalization styles.
+
+\startaside
+Some bibliographic database sources can be quite sloppy and return strings
+(titles and even authors) in all capitals, for example. We have made the design
+choice \emphasis {not} to follow the \BIBTEX\ practice/feature of explicitly
+formatting all string values, as we did not want to require the protection
+through enclosing curly brackets that would have been a necessary consequence.
+Thus, some cleaning of these database files might be needed. Furthermore, we
+attempt to use all the power of \CONTEXT\ and \LUA, thus making unnecessary much
+(most?) of the \TEX-like encoding of the data. We encourage users to clean|-|up
+their \Tindex {.bib} database files as much as possible so that they contain only
+the necessary data, with a minimum of explicit formatting directives.
+\stopaside
+
+String values, as described above, can be enclosed indifferently between matching
+curly brackets: \BTXcode {{}} or pairs of quotation marks: \BTXcode {""}.
+Multiple string values can be \index {string concatenation}concatenated using the
+operator \BTXcode {\#}, as will be illustrated in \in {table}
+[tab:mkiv-publications.bib].
+
+Everything outside of a valid entry is ignored and treated as a \Index {comment}.
+Syntactic errors (such as a missing comma or some unbalanced quotes or
+parenthesis) are also skipped over, i.e. ignored. This is to attempt to continue
+on to valid data but may lead to unexpected results. It is therefore the user's
+responsibility to insure the correctness of the data files. Whereas some checks
+and warnings are issued, the system is purposefully not too verbose.
+
+Data is handled on a \quote {first come, first served} basis: duplicate \index
+{duplicate+fields}\emphasis {fields} in an entry are ignored \startfootnote Note
+that some \BIBTEX\ practice allows for the concatenation of duplicate name \index
+{duplicate+fields}fields (i.e. \BTXcode {author} and \BTXcode {editor}) through
+\BTXcode {and}, but (silently) ignores duplicate other fields. We choose to have
+a consistant behavior and disallow duplicate field occurrences. \stopfootnote
+though duplicate \index {duplicate+entries}\emphasis {entries} (having the same
+\index {duplicate+tags}tag) are retained, but the subsequent identical \Index
+{tag}s will be modified by adding a suffix $-n$ for the $n$\high {th} duplicate.
+The presence of duplicate \index {duplicate+fields}fields or \index
+{duplicate+tags}tags will be flagged as such with warnings in the log file.
+Duplicate \index {duplicate+entries}entries using different \Index {tag}s will
+not be treated as duplicates.
+
+A special provision has been made to declare author \Index {synonyms}, that is
+names that might occur with a variation of spellings or aliases. This shall be
+discussed later.
+
+We have attempted to remain compatible with the \BIBTEX\ format, and any new
+bibliography extensions that we introduce here were designed in a way to remain
+compatible with \BIBTEX, being simply ignored rather than potentially generating
+a \BIBTEX\ error.
+
+The \BIBTEX\ files are loaded in memory as \LUA\ table but can be converted to
+\XML\ so that we can access them in a more flexible way, but that is another
+subject for specialists.
+
+\stopsection
+
+\startsection [reference=sec:Commands,title=Commands in entries]
+
+One unfortunate aspect commonly found in \BIBTEX\ files is that they may contain
+\TEX\ commands. Even worse is that there is no standard on what these commands
+can be and what they mean, at least not formally, as \BIBTEX\ is a program
+intended to be used with many variants of \TEX\ style: plain, \LATEX, and others.
+This means that we need to define our use of these typesetting commands. (In
+particular, one might need to redefine those that are too \LATEX|-|centric.)
+However, in most cases, they are just abbreviations or font switches and these
+are often well known. Therefore, \CONTEXT\ will try to resolve them before
+reporting an issue. The log file will announce the commands that have been seen
+in the loaded databases. For instance, loading \Tindex {tugboat.bib} (distributed
+with \TEXLIVE) gives a long list of commands of which we show a small set of the
+five most frequently encountered ones here:
+
+\startbuffer
+\definebtxdataset[tugboat]
+\usebtxdataset[tugboat][tugboat.bib]
+\stopbuffer
+
+\getbuffer
+
+\starttyping
+publications > tugboat  tt     134 known
+publications > tugboat  Dash   136 unknown
+publications > tugboat  acro   137 known
+publications > tugboat  LaTeX  209 known
+publications > tugboat  TeX    856 known
+\stoptyping
+
+Some are flagged as known and others as unknown. You can define unknown commands,
+or overload existing definitions in the standard way (\emphasis {e.g.} \TEXcode
+{\def\Dash{—}}), the \CONTEXT\ way (\TEXcode {\define\Dash{—}}) or,
+alternatively, in the following way:
+
+\cindex {definebtxcommand}
+
+\startTEX
+\definebtxcommand\TUB {TUGboat}
+\definebtxcommand\MP  {METAPOST}
+\definebtxcommand\sltt{\tt}
+\definebtxcommand\<#1>{\type{#1}}
+\stopTEX
+
+\definebtxcommand\MP  {METAPOST} % to be used silently below
+
+Custom commands created using \Cindex {definebtxcommand} have the advantage of
+using a separate name space thus allowing \Index {isolation} from other \CONTEXT\
+commands. (The \Index {isolation} of \Cindex {btxcommand} allows the \Tindex
+{.bib} files to safely contain \TEX\ and \LATEX\ idiosyncrasies that might
+conflict with proper \CONTEXT\ syntax.) Unknown commands do not stall processing,
+but their names are then typeset in a mono|-|spaced font so they probably stand
+out for proofreading. You can access the commands using \index
+{btxcommand}\TEXcode {\btxcommand{...}} (or \Cindex {btxcmd}), as in:
+
+\startbuffer
+commands like \btxcommand{MySpecialCommand} are handled in an indirect way
+\stopbuffer
+
+\cindex {btxcommand}
+
+\typeTEXbuffer
+
+As this is an undefined command we get: \quotation {\inlinebuffer}.
+
+Often, these embedded \TEX\ commands are present in \Tindex {.bib} files in order
+to trick \BIBTEX\ into certain behavior. Since this will generally not be
+necessary here, we strongly encourage users to clean|-|up such unnecessary
+extras. Indeed, the idea is to keep the data clean, using styles and parameter
+settings instead to handle rendering issues. Indeed, we don't see it as challenge
+nor as a duty to support all kinds of messy definitions. Of course, we try to be
+somewhat tolerant, but you will be sure to get better results if you use nicely
+setup, consistent databases.
+
+Finally, the \BIBTEX\ entry \tindex {@string}\BTXcode {@String{}} is preprocessed
+as expected.
+
+\tindex {@string}
+
+\startTEX
+@String{j-TUGboat = "TUGboat"}
+\stopTEX
+
+\startaside
+Notice that \Tindex {tugboat.bib} also contains: \tindex {@preamble}

+
+In the old \MKII\ setup we have two kinds of entries: the ones that come from the

+output but we do still support the user supplied definitions. These were in fact
+prepared in a way that suits the processing of the \BIBTEX\ generated entries;
+The next variant reflects the \CONTEXT\ recoding of the old \BIBTEX\ output. For

+\startsection[title=Other formats]
+
+Various other bibliographic data file formats are in common use, such as:

+\stoptabulate
+
+just to name a few (amongst many more). Filters can be easily written in \LUA\ to
+read these and other bibliography data formats, although no such filters are
+provided. This is because the user has a choice of a certain number of
+bibliography database management programs that can easily convert from these to
+the \BIBTEX\ format. (Notable, open source examples are \index {jabref} \goto
+{jabref} [url(http://jabref.sourceforge.net)] and \index {zotero} \goto {zotero}
+[url(http://www.zotero.org)].) Indeed, it is not the vocation of the present
+\CONTEXT\ bibliography subsystem to fully manage the bibliography data sources,
+only to be able to use such data in the production of documents.
+
+\startaside
+\emphasis {A note on database management programs:} these are very valuable tools
+for the manipulation of bibliography database information, which is why the
+\BIBTEX\ format has so much importance for us here. However, one must be aware
+that these programs are not standards and many of them may introduce invalid
+extensions that might not even be handled correctly by \BIBTEX\ itself.

+\startchapter[title=Datasets]
+
+Normally in a document you will use only one bibliographic database, whether or
+not its source is distributed over multiple files. Nevertheless, we support
+multiple database formats as well which is why we talk of datasets instead. The
+use of multiple datasets allows the isolation of different bibliographies (a
+single bibliography can nevertheless be rendered by structure element: section,
+chapter, part, etc. as we shall see later). A good example of the use of multiple
+datasets would be for a proper bibliography itself in addition to a reference
+catalog (of equipment, suppliers, software, patents, legal jurisprudence, music,
+\unknown). Indeed, datasets can be used to hold both bibliographic and
+non|-|bibliographic information.
+
+A dataset is initiated with the \Cindex {definebtxdataset} command.
+
+\cindex {definebtxdataset}
+
+\startTEX
+\definebtxdataset[default]
+\stopTEX
+
+\startaside
+A default database, \TEXcode {default}, is predefined, yet we recommend defining
+it explicitly because in the future we may provide more options.
+\stopaside
+
+Like other commands in \CONTEXT, the dataset options can be setup using the
+command \Cindex {setupbtxdataset}.
+
+\cindex {definebtxdataset}
+\showsetup[definebtxdataset]
+
+\cindex {setupbtxdataset}
+\showsetup[setupbtxdataset]
+
+A dataset is loaded from some source through the use of the
+\Cindex {usebtxdataset} command.
+
+Here are some examples:
+
+\cindex {usebtxdataset}
+\tindex {.bib}
+\tindex {.xml}
+\tindex {.lua}
+\tindex {.bbl}
+
+\startTEX
+\usebtxdataset[tugboat][tugboat.bib]
+\usebtxdataset[default][mtx-bibtex-output.xml]
+\usebtxdataset[default][test-001-btx-standard.lua]
+\usebtxdataset[default][mkii-publications.bbl]
+\usebtxdataset[default][named.buffer]
+\stopTEX
+
+\cindex {usebtxdataset}
+\showsetup[usebtxdataset]
+
+The four suffixes illustrated in the example above are understood by the loader.
+Here the dataset (other than the first) has the name \TEXcode {default} and the
+four database files are merged. The last example shows that a \TEXcode {named}
+\Index {buffer} can also be employed to add dataset entries (in \BIBTEX\ format).
+This may be useful for small additions or examples, but it is generally a better
+idea (for convenience of management of data) to place them in files separate from
+the document source code.
+
+Definitions in the document source (coded in \TEX\ speak) are also added, and
+they are saved for successive runs. This means that if you load and define
+entries, they will be known at a next run beforehand, so that references to them
+are independent of where in the document source loading and definitions take
+place. This is convenient to eventually break|-|up the dataset loading calls to
+relevant sections of the document structure.
+
+In this document we use some example databases, so let's load one of them now:
+\startfootnote This code snippet demonstrates that \TEXcode {\usebtxdataset} will
+implicitly declare an undefined dataset name, although this practice is to be
+discouraged. Similarly, omitting to specify the dataset name \TEXcode {[default]}
+in the examples given earlier would fall|-|back correctly, but this, too, is to
+be discouraged as being potentially error|-|prone. \stopfootnote
+
+\startbuffer
+\usebtxdataset[example][mkiv-publications.bib]
+\stopbuffer
+
+\cindex {definebtxdataset}
+\cindex {usebtxdataset}
+
+\typeTEXbuffer
+
+\getbuffer
+
+The beginning of the file \type {mkiv-publications.bib} is shown below in \in
+{table} [tab:mkiv-publications.bib]. This bibliography database test file
+contains one entry of each standard type or category, with the \Index {tag} set
+to the entry type name. This entry shown here illustrates many features that will
+be explained elsewhere in the text.
+
+\startsection[title=Dataset coverage]
+
+You can load much more data than you actually need. Usually only those entries
+that are referred to explicitly will be shown in lists, and commands used to
+select these dataset entries will described in \in {chapter} [ch:cite].
+
+A single bibliography list can span groups of datasets; also multiple datasets
+can loaded from the same source, for example, one per chapter, in order to
+achieve a complete \Index {isolation} of bibliographies with respect to numbering
+and references.
+
+As this concept is not obvious but can be quite useful, we will repeat this last
+point: multiple datasets can be loaded using the same source file, i.e.\
+containing the same data, to be used in parallel, independently. There is little
+penalty in keeping even very large datasets as multiple copies in memory.
+
+The current active dataset to be used by default can be set with
+
+\startbuffer
+\setupbtx[dataset=example]
+\stopbuffer
+
+\cindex {setupbtx}
+
+\typeTEXbuffer
+
+\getbuffer
+
+However, most publication|-|related commands accept optional arguments that
+denote the dataset and references to entries can always be prefixed with a
+dataset identifier. More about that later.
+
+\showsetup[setupbtx]
+
+\stopsection
+
+\startsection [title=Specification]
+
+The content of a dataset can really be anything: entries of type (or categories)
+of all sorts, each containing arbitrary fields. The use to be made of this data
+can vary greatly since the system is not limited to the production of
+bibliography lists, in particular. The intended use is reflected through a set of
+specifications, specific to each bibliography (or non|-|bibliography) style.
+These specifications affect the interpretation of dataset categories and fields
+as well as their rendering. They will also affect the rendering of citations or
+the reference or invocation of individual data entries.
+
+The \TEXcode {default} bibliography specification is very simple: only the
+categories \TEXcode {book} and \TEXcode {article} are explicitly defined. These
+were shown along with their default rendering in the quick|-|start example on \at
+{page} [ch:quick]. We purposely limited this \TEXcode {default} specification as
+a minimal example for a bibliography.
+
+The notion of categories and the fields that they might contain and their
+interpretation depend on a particular specification, although the dataset
+\emphasis {content} is independent of all eventual rendering specifications that
+may be applied.
+
+An alternative set of specifications can be selected using, for example
+
+\startbuffer
+\usebtxdefinitions[apa]
+\stopbuffer
+
+\cindex {usebtxdefinitions}
+\index {style+APA}
+\seeindex {specification}{style}
+
+\typeTEXbuffer
+
+\getbuffer
+
+Alternately, the set of specifications can be loaded and (later) activated using
+
+\cindex {loadbtxdefinitionfile}
+\cindex {setupbtx}
+\index {style+APA}
+
+\startTEX
+\loadbtxdefinitionfile[apa]
+...
+\setupbtx[specification=apa]
+\stopTEX
+
+but it is safer to use the \TEXcode {\use} rather than \TEXcode {\load} form, in
+particular with specifications that may themselves have several variants. Also,
+it is way too easy to later forget to set the \TEXcode {specification} parameter
+and then wonder why the loaded specification was not applied.
+
+\startaside
+We wish to clarify that each specification defines the categories of entries and
+the interpretation or use of the fields that they contain, but does not alter the
+data itself, only how this data is used. It also defines \emphasis {setups} that
+control the rendering of lists as well as citations (to be described below).
+Additionally, it creates a namespace with settings for particular \emphasis
+{parameters} controlling the formatting of names, for example, punctuation as
+well as other stylistic features. The user can tune or overload these settings as
+needed.
+\stopaside
+
+A specification need not be activated before loading a dataset; indeed the
+contents of a dataset are stored independent of the specification, and multiple
+specifications can be applied to the same dataset (although this will not usually
+be the case). Furthermore, multiple specification files can be loaded
+simultaneously as they reside in separate namespaces, but only one specification
+can be selected at a time. We introduce these commands here in the context of
+datasets as the labeling of categories and of field use can change depending on
+the specification. Indeed, some specifications might ignore certain fields
+present in the dataset that may be used with other specifications. The details of
+how this is programmed will be explained in \in {Chapter} [ch:custom].
+
+So a specification is both a definition of how a dataset is to be interpreted as
+well as stylistic tuning of how it is to be rendered.

+\startsection [title=Dataset diagnostics]
+
+You can ask for an overview of entries present in a dataset with:
+
+\startbuffer
+\showbtxdatasetfields[example]
+\stopbuffer
+
+\cindex {showbtxdatasetfields}
+
+\typeTEXbuffer
+
+The listing that this produces is shown in \in {Appendix} [ch:datasetfields].
+
+\cindex   {showbtxdatasetfields}
+\showsetup[showbtxdatasetfields]
+\showsetup[showbtxdatasetfields:argument]
+
+Sometimes you might want to check a database, listing all of its entries in
+detail. This can be particularly useful when in doubt concerning the correctness
+or the completeness of the data source, remembering that invalid entries and some
+syntax errors are simply skipped over. One way of examining the loaded dataset in
+detail is the following:
+
+\startbuffer
+\showbtxdatasetcompleteness[example]
+\stopbuffer
+
+\cindex {showbtxdatasetcompleteness}
+
+\typeTEXbuffer
+
+The diagnostic listing (which can be rather long) is shown in \in {Appendix}
+[ch:datasetcompleteness].
+
+\cindex   {showbtxdatasetcompleteness}
+\showsetup[showbtxdatasetcompleteness]
+\showsetup[showbtxdatasetcompleteness:argument]
+
+The dataset contains many entries and each entry is assigned to a \Index
+{category}. It must be stressed, so we repeat ourselves here, that these \quote
+{categories} can be of any sort whatsoever, the meaning of which resides in the
+rendering style that is chosen. The entries contain fields, and these too can be
+of any sort; their use also depends on the rendering style and the \Index
+{category} in which they belong. \BibTeX\ has conventionally defined a number of
+standard categories, each making use of a number of fields considered either
+\index {field+required}required, \index {field+optional}optional or \index
+{field+ignored}ignored. However, different traditional \BIBTEX\ rendering styles
+can make inconsistant use of these standard categories and fields. To make
+matters worse, different \Tindex {.bib} database handling programs might use (and
+impose) differing \quote {standards} as well, as mentioned above. \startfootnote
+For example, \Tindex {jabref}, in addition to discarding all comments contained
+in the database file, will convert all unrecognized, preciously named categories
+to \tindex {@other}\BTXcode {@Other}! Of course, \Tindex {jabref} is flexible
+enough to be configured with new categories and additional fields, so users of
+\Tindex {jabref} with \CONTEXT\ will probably want to use an extended, custom
+configuration. \stopfootnote This situation arises from the complexity of
+handling bibliographic data of all sorts.
+
+You can see all (currently known) \index {category}categories and \index
+{field}fields with:
+
+\cindex {showbtxfields}
+
+\startTEX
+\showbtxfields[rotation=...]
+\stopTEX
+
+The result is shown \in {table} [tab:fields], below.
+
+\cindex   {showbtxfields}
+\showsetup[showbtxfields]
+\showsetup[showbtxfields:argument]
+
+Note that other, possibly non|-|bibliographic use of the present dataset system
+might define entirely different categories and field types, possibly having
+nothing at all to do with the names shown here. An example of such use is given
+in \in {chapter} [ch:duane].
+
+Just as a database can be much larger than needed for a document, the same is
+true for the fields that make up an entry; not all entry fields will be
+necessarily used. This idea will be developed in the next section describing the
+rendering of bibliography lists.

+
+A dataset can be much more complete than necessary. Furthermore, it may be
+desirable to isolate bibliography data by chapter, for example, or by any other
+structural element such as part. To achieve this, it is possible to export the
+entries of a dataset following certain criteria.
+
+\cindex{savebtxdataset}
+
+Take as an example, the bibliography of the present manual that was entered in
+the source as buffers for convenience. The entries can be saved to a legitimate
+\BIBTEX\ format file using:
+
+\startTEX
+\savebtxdataset
+  [default]
+  [mkvi-publications.bib]
+  [alternative=bib,
+   criterium=all]
+\stopTEX
+
+This can also be used to convert older bibliography source files (for example,
+kept in the \tindex {.bbl}\MKII\ format) into the \tindex {.bib}\type {bib},
+\tindex {.lua}\type {lua} or even \tindex {.xml}\type {xml} format that could be
+more convenient for future manipulation.

+As \TEX\ and \LUA\ are both open and accessible in \CONTEXT\ it is possible to

+\startluacode

+\startsubject[title=How Hans got involved]
+
+This manual is dedicated to Taco \Name{Hoekwater}{T.} who in a previous century
+implemented the first \BIBTEX\ module and saw it morph into a \TEX||\LUA\ hybrid
+in this century. The fact that there was support for bibliographies made it
+possible for users to use \CONTEXT\ in an academic environment, dominated by
+bibliographic databases encoded in the \BIBTEX\ format.
+
+This manual describes how \MKIV\ now handles bibliographies. Support in \CONTEXT\
+started in \MKII\ for \BIBTEX, as mentioned above, using a module written by Taco
+\Name {Hoekwater} {T.}. Later his code was adapted to \MKIV, but because users
+demanded more, I decided that reimplementing made more sense than patching. In
+particular, through the use of \LUA, the \BIBTEX\ data files can be easily
+directly parsed, thus liberating \CONTEXT\ from the dependency on an external
+\BIBTEX\ executable. The \Index{CritEd project} (by Thomas \Name {Schmitz} {T.},
+Alan \Name {Braslau} {A.}, Luigi \Name {Scarso} {L.} and \name {Hagen}
+{H.}myself) was a good reason to undertake this rewrite. As part that project
+users were invited to come up with ideas about extensions. Not all of them are
+(yet) honored, but the rewrite makes more functionality possible.
+
+The subsystem described here is one of the most complex and messy of all
+\CONTEXT\ subsystems. This has to do with the fact that it combines (multiple)
+lists and (multiple) forward and backward references, all kind of rendering of
+the citation as well as the entry in the list, rather complex interactivity,
+multiple databases, datasets and renderings and of course combinations of this.
+The implementation uses a mix of \TEX\ and \LUA\ code with so called setups as
+rendering specifications. At the cost of complexity (and some runtime penalty)
+this provides a lot of freedom and flexibility.

+
+Bibliographies and citations are of utmost importance in any scholarly work.
+Nevertheless, the production of bibliography lists and the insertion of
+citations, just like the production of an index, is a task that is often
+postponed to a later stage in the writing of an article, a book, or a manual.
+Perhaps this is because it can be more important to create than to refer, but
+maybe the necessary tools are found to be insufficient or unnatural.
+
+A computerized typesetting system should help an author produce a text, not
+impose any preset format or unnecessary constraint. In a referenced work, a
+bibliography system should be flexible enough to adapt to very different styles
+and practices. Creating such a system is quite a challenge.
+
+\CONTEXT\ \MKII\ implemented a system that was based on a use of \BIBTEX, an
+external program that built upon basic bibliographic macros introduced in \LATEX.
+\CONTEXT\ \MKIV\ moved away from this dependency, opening up many possibilities
+for new functionality and, we hoped, providing more natural and flexible tools
+for authors. For my own use, the most important of which is a very powerful
+search and match mechanism that has been made possible though the use of \LUA.
+
+I had started by asking simple questions on details of the workings of this new
+system and making \quotation{wouldn't it be nice to} requests for functionality
+that I knew was somehow buried in the inner workings of \CONTEXT. As a result of
+these inquiries, I got drawn into the project to make this new system a reality.

+
+Bibliography management is indeed one of the most complex subsystems in \CONTEXT,
+and many, many design decisions had to be made during its development.
+Experimental features were added, some of which were later abandoned as being
+inappropriate or else superseded by some better mechanism. The effort (and time)
+that we spent in reimplementing the treatment of bibliographies was much greater
+than any of us had anticipated when we undertook this project. Hopefully, now the
+system is stable enough to be more widely used and this manual is an attempt to
+make it accessible to all users.
+
+There are \CONTEXT\ users who will just use whatever the bibliograpy modules
+provide by default. For many, the \APA\ style is good enough; others may have
+specific needs. This manual should provide insight on how to adapt the system to
+new styles. But sometimes users will ask questions on the mailing list that are
+not answered here. Feel free to come up with additional examples that can be
+added to the test suite, or when we consider them to be of general use, to this
+manual.

+An experimental feature is the ability to load a list of mapping from complete
+journal names to abbreviated forms.
+
+\startbuffer
+\btxloadjournallist[journals.txt] % the jabref list
+
+\btxexpandedjournal   {Z. Ökol. Nat.schutz} or
+\btxabbreviatedjournal{Z. Ökol. Nat.schutz} or
+\btxabbreviatedjournal{Z. Ökol. Nat. schutz}
+\stopbuffer
+
+\typeTEXbuffer \getbuffer
+
+In this case the text file looks like:
+
+\starttyping
+Zeitschrift für Ökologie und Naturschutz = Z. Ökol. Nat..schutz
+....
+\stoptyping
+
+Instead you can have a \LUA\ file that looks like:
+
+\startLUA
+return {
+    ["Zeitschrift für Ökologie und Naturschutz"] = "Z. Ökol. Nat.schutz",
+    ...
+}
+\stopLUA
+
+or
+
+\startLUA
+return {
+    { "Zeitschrift für Ökologie und Naturschutz", "Z. Ökol. Nat.schutz" },
+    ...
+}
+\stopLUA
+
+A file can be saved with:
+
+\startTEX
+\btxsavejournallist[journals.lua]
+\stopTEX
+
+and then loaded again in a second run. For small lists it makes not much sense
+to cache the lists but if you have tens thousands of journals it can be
+considered. Normally loading is can be neglected compared to the run. Anyhow,
+such a list looks like this:
+
+\startLUA
+return {
+    ["abbreviations"]={
+        ["zeitschriftfürökologieundnaturschutz"] = "Z. Ökol. Nat.schutz",
+    },
+    ["expansions"]={
+        ["zökolnatschutz"] = "Zeitschrift für Ökologie und Naturschutz",
+    },
+}
+\stopLUA
+
+In the future \type {mtx-bibtex} might be able to generate such lists (once we know
+what users come up with).
+
+You can add additional entries with:
+
+\startTEX
+\btxaddjournal
+  [Zeitschrift für Ökologie und Naturschutz]
+  [Z. Ökol. Nat.schutz]
+\stopTEX
+
+As usual with such mechanisms, internally spaces, punctuation and case are
+ignored with a lookup.
+
+There are also two manipulators for journals: \type {expandedjournal} and
+\type {abbreviatedjournal}.

+\startchapter[title=The \LUA\ view]
+
+The following is reserved for \LUA\ programmers.
+
+Because we manage data at the \LUA\ end it is tempting to access it there for
+other purposes. This is fine as long as you keep in mind that aspects of the
+implementation may change over time, although this is unlikely once the modules
+become stable.
+
+The entries are collected in datasets and each set has a unique name. In this
+document we have the set named \type {example}. A dataset table has several
+fields, and probably the one of most interest is the \type {luadata} field. Each
+entry in this table describes a publication. Take, for example \type
+{publications.datasets.example.luadata["article"]}:
+
+\startluacode
+    context.tocontext(publications.datasets.example.luadata["article"])
+\stopluacode
+
+There is a companion entry in the parallel \type {details} table,\\
+\type {publications.datasets.example.details["article"]}:
+
+\startluacode
+    context.tocontext(publications.datasets.example.details["article"])
+\stopluacode
+
+tracking further information derived from the publication entry and its use.
+
+You can loop over the entries using regular \LUA\ code combined with \MKIV\
+helpers:
+
+\startbuffer
+local dataset = publications.datasets.example
+
+context.starttabulate { "|l|l|l|" }
+context.NC() context("tag")
+context.NC() context("short")
+context.NC() context("title")
+context.NC() context.NR()
+context.HL()
+for tag, entry in table.sortedhash(dataset.luadata) do
+    local detail = dataset.details[tag] or { }
+    context.NC() context.type(tag)
+    context.NC() context(detail.shorthash)
+    context.NC() context(entry.title)
+    context.NC() context.NR()
+end
+context.stoptabulate()
+\stopbuffer
+
+\typeLUAbuffer
+
+This results in:
+
+\ctxluabuffer
+
+Notice that the years in this example dataset given as \type {YYYY} are
+interpreted as if they were \index {9999}\type {9999}.
+
+You can manipulate a dataset after loading. Of course this assumes that you know
+what kind of content you have and what you need for rendering. As example we load
+a small dataset.
+
+\startbuffer

+
+\cindex{definebtxdataset}
+\cindex{usebtxdataset}
+
+\typeTEXbuffer
+
+\getbuffer
+
+Because we're going to do some \LUA, we could have loaded this dataset using:
+
+\startTEX
+\startluacode
+publications.load("drumming","mkiv-publications.lua","lua")
+\stopluacode
+\stopTEX
+
+The dataset has three entries:%
+\startfootnote
+Gavin Harrison is in my (Hans) opinion one of the most creative, diverse and
+interesting drummers of our time. It's also fascinating to watch him play and a
+welcome distraction from writing code and manuals.
+\stopfootnote
+
+\typeLUAfile{mkiv-publications.lua}
+
+As you can see, we can have a subtitle. As an exercise, we will combine the
+title and subtitle into one:
+
+\startbuffer
+\startluacode
+local luadata = publications.datasets.drumming.luadata
+
+for tag, entry in next, luadata do
+    if entry.subtitle then
+        if entry.title then
+            entry.title = entry.title .. ", " .. entry.subtitle
+        else
+            entry.title = entry.subtitle
+        end
+        entry.subtitle = nil
+        logs.report("btx",
+            "combining title and subtitle of entry tagged %a into %a",
+            tag,entry.title)
+    end
+end
+\stopluacode
+\stopbuffer
+
+\typeTEXbuffer \getbuffer
+
+As a hash comes in a different order each run (something that demands a lot of
+care in multi|-|pass workflows that save data in between), so it is probably
+better to use this instead:
+
+\startTEX
+\startluacode
+local ordered = publications.datasets.drumming.ordered
+
+for i=1,#ordered do
+    local entry = ordered[i]
+    if entry.subtitle then
+        if entry.title then
+            entry.title = entry.title .. ", " .. entry.subtitle
+        else
+            entry.title = entry.subtitle
+        end
+        entry.subtitle = nil
+        logs.report("btx",
+            "combining title and subtitle of entry tagged %a into %a",
+            entry.tag,entry.title)
+    end
+end
+\stopluacode
+\stopTEX
+
+This loops processes in the order of definition. Alternately, one can sort by
+\Index{tag}:
+
+\startTEX
+\startluacode
+local luadata = publications.datasets.drumming.luadata
+
+for tag, entry in table.sortedhash(luadata) do
+    if entry.subtitle then
+        if entry.title then
+            entry.title = entry.title .. ", " .. entry.subtitle
+        else
+            entry.title = entry.subtitle
+        end
+        entry.subtitle = nil
+        logs.report("btx",
+            "combining title and subtitle of entry tagged %a into %a",
+            entry.tag,entry.title)
+    end
+end
+\stopluacode
+\stopTEX
+
+The original data is stored in a \LUA\ table, hashed by tag. Starting with \LUA\ 5.2
+each run of \LUA\ gets a different ordering of such a hash. In older versions, when you
+looped over a hash, the order was undefined, but the same as long as you used the same
+binary. This had the advantage that successive runs, something we often have in document
+processing gave consistent results. In today's \LUA\ we need to do much more sorting of
+hashes before we loop, especially when we save multi||pass data. It is for this reason
+that the \XML\ tree is sorted by hash key by default. That way lookups (especially
+the first of a set) give consistent outcomes.
+
+We can now simply typeset the entries with:
+
+\cindex{definebtxrendering}
+\cindex{placebtxrendering}
+
+\startbuffer
+\definebtxrendering[drumming][group=examples,dataset=drumming]
+\placebtxrendering[drumming][method=dataset]
+\stopbuffer
+
+\typeTEXbuffer \getbuffer
+
+Because we just want to show the entries, and have no citations that force them
+to be shown, we have to set the \type {method} to \type {dataset}.
+
+Of course, none of these manipulations in \LUA\ are really necessary, as the
+rendering could be setup as:
+
+\cindex {btxfetch}
+\cindex {btxdoif}
+\cindex {btxcomma}
+\cindex {starttexdefinition}
+\cindex {stoptexdefinition}
+
+\startTEX
+\starttexdefinition btx:default:title
+    \btxfetch{author}
+    \btxdoif{subtitle} {
+        \btxcomma
+        \btxfetch{subtitle}
+    }
+\stoptexdefinition
+\stopTEX
+
+which is indeed the case in many of the styles (the \type {default} style uses
+\Cindex {btxcolon}). \startfootnote The specifications could be modified to use a
+parameter \type {inbetween={, }} for titles:subtitles that the user can easily
+setup as needed. But as such style questions are, in general, well defined in the
+specifications, this was not deemed necessary. \stopfootnote
+
+It is always a question of how much should be done in \LUA\ and how much should
+be done in \TEX. In the end, it is often a question of taste.

+
+Like above, we shall define a named dataset and load it with definitions having

+Note that the specification \quote {chemistry} is undefined (as yet) so the log file shows:

+
+This is harmless as a missing (lua) definition file makes \emphasis {all} data categories and fields

+The dataset (containing just 4 of the 57 entries) is:
+
+\startparagraph [style=small]
+\getbuffer
+\stopparagraph
+
+The next step is to activate the specification and dataset and to define a list rendering, as
+follows:
+
+\startbuffer
+\setupbtx
+  [specification=chemistry,
+   dataset=chemistry]
+
+\definebtxrendering
+  [chemistry]
+  [specification=chemistry,
+   group=chemistry,
+   dataset=chemistry]
+\stopbuffer
+
+\cindex{setupbtx}
+\cindex{definebtxrendering}
+\typebuffer [option=TEX]
+\getbuffer
+
+This list rendering can then be placed, but first one needs to create a setup
+describing how to handle the entry (or category) \type {@chemical{}} contained
+in the file \type {C6H6O.bib}. As in the earlier example, we shall use a table
+structure for the list text:
+
+\startbuffer
+\startsetups btx:chemistry:list:chemical
+  \startframed [frame=off,location=middle]
+  \bTABLE [frame=off]
+    \bTR

+\cindex{startsetups}
+\cindex{stopsetups}
+\typebuffer [option=TEX]
+
+Note that not all fields of the dataset are used.
+
+\getbuffer
+
+The real usefulness of the dataset is the possibility of referring to entries
+and the ability to extract data fields. Setups can be defined for those fields
+requiring any formatting beyond a simple flushing, for example those requiring

+\startchapter[title=Performance]
+
+The move from external \BIBTEX\ processing to internal processing has the
+advantage that we stay within the same run. In the traditional approach we had
+roughly the following steps:
+
+\startitemize[packed]
+\startitem
+    In the first \CONTEXT\ run information is collected and written to file.
+\stopitem
+\startitem
+    fter the first run the \BIBTEX\ program converts that file to another
+    one, a so called \type {bbl} file with \TEX\ commands.
+\stopitem
+\startitem
+    Successive runs use that file for typesetting references and producing
+    lists of publications that are reffered to.
+\stopitem
+\stopitemize
+
+In the \MKIV\ approach the bibliographic database is loaded in memory each run
+and processing also happens each run. On paper this looks less efficient but as
+\LUA\ is quite fast, in practice performance is much better.
+
+Probably most demanding is the treatment of authors as we have to analyze names,
+split multiple authors and reassemble firstnames, vons, surnames and juniors.
+When we sort by author sorting vectors have to be made which also has a penalty.
+However, in practice the user will not notice a performance degradation. We did
+some tests with a list of 500.000 authors, sorted them and typeset them as list
+(producing some 5400 dense pages in a small font and with small margins). This is
+typical one of these cases where using \LUAJITTEX\ saves quite time. On my
+machine it took just over 100 seconds to get this done. Unfortunately not all
+operating systems performed equally well: 32 bit versions worked fine, but 64 bit
+\LINUX\ either crashed (stalled) the machine or ran out of memory rather fast,
+while \MACOSX\ and \WINDOWS\ performed fine. In practice you will never run into
+this, unless you produce massive amounts of bibliographic entries. \LUAJIT\ has
+some benefits but also some drawbacks. In practice you will not run into these
+problems.

+\startchapter[title=Renderings,reference=ch:renderings]

+\startsection
+  [reference=sec:styles,
+   title={Generating lists of publications}]
+
+A list of publications can be rendered at any place in the document, and multiple
+renderings can appear under certain limitations (according to \Index {scope}).
+The specification introduced previously defines the style of the rendering as
+well as what data it will contain.
+
+If you want to see what publications are in the database, the easiest way is to
+ask for a complete list:
+
+\startbuffer
+\usebtxdataset            % illustrated again here
+  [example]               % although already loaded
+  [mkiv-publications.bib] % in the previous chapter
+
+\definebtxrendering
+  [example]               % named rendering
+  [apa]                   % parent namespace
+  [dataset=example,
+   group=examples]        % group will be presented later
+
+\placelistofpublications  % aka \placebtxrendering
+  [example]               % rendering defined above
+  [method=dataset]        % i.e. all entries
+\stopbuffer
+
+\cindex{definebtxrendering}
+\cindex{placelistofpublications}
+\cindex{placebtxrendering}
+
+\typeTEXbuffer
+
+The commands \Cindex {placelistofpublications} (that is just a synonym for
+\Cindex {placebtxrendering}) refer to a named rendering and accept a list of
+options (inherited from \Cindex {setupbtxrendering}). When applied to a named
+dataset (other than \TEXcode {default}), a named rendering needs to be associated
+through \Cindex {definebtxrendering} as is done here.
+
+Note that the define shown above explicitly inherits from a rendering named
+\TEXcode {apa} that was itself defined when loading the specification file.
+\startfootnote The rendering parent \index {style+APA}\TEXcode {[apa]} sets the
+parameters: \TEXcode {specification=apa,} \TEXcode {sorttype=authoryear,} and
+\TEXcode {numbering=no,} described below. It also sets various list parameters in
+a protected \TEXcode {apa} namespace to produce a \quote {hanging} bibliography
+list. \stopfootnote Had this inheritance not been specified, the new rendering
+would inherit default, minimal settings. This notion of inheritance will be
+further illustrated later.
+
+The bibliography list rendering of our example dataset, following the \index
+{style+APA}APA style, is:
+
+\getbuffer
+
+The rendering is a list whose appearance can be tuned, as any list in \CONTEXT.
+It is somewhat more complex to manage, though, because we can have not only many
+different standards but also many fields that can be set up. This means that
+there are several commands involved. As we saw demonstrated above, a rendering is
+defined and setup using the commands:
+
+\cindex{definebtxrendering}
+
+\showsetup{definebtxrendering}
+
+\cindex{setupbtxrendering}
+
+\showsetup{setupbtxrendering}
+
+A rendering is then placed using \Cindex {placebtxrendering}, a \CONTEXT\ command
+that accepts the same arguments as for its setup. Using \TEXcode
+{method=dataset}, as above, one renders the entire contents of the dataset.
+Normally, however, one would not use this \TEXcode {method} and place only a
+selection of entries that are to be used in the document, whereas the dataset may
+very well contain many other, unused references. The \TEXcode {method=global} or
+\TEXcode {method=local} option can be used to specify if this use is to be global
+for the entire document or else local to a structure element such as a part or a
+chapter.
+
+\cindex{placebtxrendering}
+
+\showsetup{placebtxrendering}
+
+\cindex{placelistofpublications}
+
+\showsetup{placelistofpublications}
+
+The rendering is a \TEXcode {list} and this reference list is numbered. These
+numbers can be displayed, or not, depending on the bibliography style
+specification through the use of the \index {numbering}\TEXcode {numbering=yes}
+or \TEXcode {no} parameter values. The \index {style+APA}APA style, illustrated
+above, normally does not number the bibliography list.
+
+The reference list is also \index {sorting}sorted, controlled by the parameter
+\TEXcode {sorttype}; here \TEXcode {sorttype=authoryear}, appropriate for the
+\index {style+APA}APA style, \Index {sorting} first by author list, then by
+publication year, then by title, finally by page. One can sort the list in many
+ways: for example \TEXcode {sorttype=index} will render the list in the order in
+which it was loaded into the dataset (see \in {table} [tab:sorttype] for an
+explanation of list sorting schemes).
+
+\startplacetable [location=force,
+  title={\TEXcode {sorttype=}},
+  reference=tab:sorttype]
+\index{sorting}
+\starttabulate [|Tp(5.5em)|p(.75\textwidth)|]
+\HL
+\NC default\\none\\cite\\list
+\NC render the list in the order in which it was built,
+    that is, in the order that references were selected from the dataset for
+    inclusion in the list. \NC \NR
+\HL
+\NC dataset\\index
+\NC sort the list according to the dataset index, that is, in the order in that
+    references were added to the dataset. \NC \NR
+\HL
+\NC reference
+\NC sort the list in alphabetical order of the citation \Index{tag}s of the
+    dataset. Note that all entries missing tags get assigned the dataset index as
+    their tag. \NC \NR
+\HL
+\NC key
+\NC sort the list in alphabetical order of the entry field \TEXcode {key}
+    (traditionally used in \BIBTEX\ as an alternate sorting key). Falls back on
+    the dataset index if no such field is present. \NC \NR
+\HL
+\NC short
+\NC sort the list in alphabetical order of the short tag (first three letters
+    of the author name or first letter of the first three authors followed by
+    the last two digits of the year). \NC \NR
+\HL
+\NC authoryear
+\NC sort the list in alphabetical order of the authors (or editors or publisher),
+    then by publication year, then by title (or by journal and volume) and
+    finally by page. \NC \NR
+\stoptabulate
+\stopplacetable
+
+As a concrete example, the rendering named \TEXcode {example} above inherits from
+the rendering instance named \TEXcode {apa} that is defined in the specification
+file as:
+
+\cindex{definebtxrendering}
+
+\startTEX
+\definebtxrendering
+  [apa]
+  [specification=apa,
+   sorttype=authoryear,
+   numbering=no]
+\stopTEX
+
+\startaside
+A more subtle characteristic of renderings is that one generally would not want a
+bibliography list to appear redundantly in a document as that would be confusing,
+unless of course it is desired that elements of the list reappear in later lists,
+for example when placing partial bibliographies at the end of each chapter and a
+complete bibliography list at the end of a book. One must specify \TEXcode
+{repeat=yes} in order to get multiple renderings of a bibliography list;
+otherwise, as they appear, entries get marked as placed and will be inhibited
+from being placed again elsewhere.
+\stopaside
+
+All renderings of bibliography lists such as the one shown earlier in this
+section also depend on a set of general list parameters that apply to each
+individual entry (a cited publication), as for any list item in \CONTEXT. These
+can be adjusted through the command \Cindex {setupbtxlist} (further described in
+\in {section} [sec:list], below). As an example, the \TEXcode {apa} specification
+file includes:
+
+\cindex{setupbtxlist}
+
+\startTEX
+\setupbtxlist
+  [apa]
+  [alternative=paragraph,
+   width=fit,
+   distance=.5em,
+   margin=3em]
+\stopTEX
+
+Such settings (yielding a hanging list that would be inappropriate with a
+numbered bibliography list) get inherited from the \TEXcode {apa} namespace in
+the rendering that we named \TEXcode {example} above.
+
+Let's try a new example (using a file taken from the \index {TUG bibliography
+archive}\goto {TUG bibliography archive}
+[url(http://ftp.math.utah.edu/pub/tex/bib/index.html)]): \startfootnote \index
+{template.bib} The file \TEXcode {template-clean.bib} is simply a copy of \TEXcode
+{template.bib} that has been cleaned|-|up to remove the empty entries.

+
+\typeTEXbuffer
+
+Here, the new rendering is defined to inherit explicitly from a rendering named
+\index {style+APS}\TEXcode {aps} (whose specification is loaded but not activated
+here). Notice, in particular, compared to the previous rendering example, that
+the list is numbered and that there is no hanging margin (it uses the standard
+list \TEXcode {alternative=b}):
+
+\getbuffer
+
+The \Index {numbering} of the references are unique and pick|-|up from where the
+previous numbering stops (the first example contains 33 references, although this
+numbering is not displayed). This behavior can be \TEXcode {method=global} for
+the entire document, or else \TEXcode {method=local}, limited to a structural
+element such as a chapter or a part. Furthermore, one can associate renderings
+into particular number groups, effectively isolating them from any other
+renderings. For example, as seen above in the rendering definitions, the present
+manual uses:
+
+\cindex{setupbtxrendering}
+
+\startTEX
+\setupbtxrendering[example] [group=examples]
+\setupbtxrendering[template][group=examples]
+\stopTEX
+
+thus setting the numbering of the group \TEXcode {examples} apart from the
+numbering of the dataset \TEXcode {default} and its named rendering (which contains
+this manual's own bibliography, to be placed later, on \at {page} [ch:biblio]).
+
+\stopsection
+
+\startsection
+  [reference=sec:styles,
+   title={Rendering styles, or more on specifications}]
+
+The default rendering style implemented in the \MKII\ module was loosely based on
+the \index {style+APA}APA standard. In contrast, we made a design choice in the
+present \MKIV\ system to provide a very minimal \TEXcode {default} style, and one
+should not expect much from this default: in fact, it only recognizes \type
+{article} and \type {book} entries (see the bibliography on \at {page}
+[ch:biblio]). A user requiring a more complete rendering will want to explicitly
+load and activate another style file. One such complete specification,
+illustrated above and appropriately named \index {style+APA}\TEXcode {apa}, is
+described in the \cite [title] [default::APA2010]. \cite [num]
+[default::APA2010]
+
+\startaside
+\emphasis {A note on the \index {style+APA}APA style:} We get the strong
+impression that the APA bibliography style standard was made with the implicit
+assumption that manual intervention would be involved in the editing and
+production process; It has been an arduous task to create a system capable of
+fully conforming to these specifications.
+
+Furthermore, we note that it has sometimes been argued that a numbered citation
+system and bibliography list is supposedly superior to the author|-|year scheme
+as is employed in the \index {style+APA}APA style (amongst others); indeed,
+handling numbered citations is certainly much easier from the point of view of
+the programmer of an automated typesetting system such as \TEX. Yet many find
+that the longer author|-|year citations can be of great use to the reader (as
+well as the writer) so we take no stand in this debate and provide both
+possibilities.
+
+We have made (and continue to make) a great effort to scrupulously respect the
+\index {style+APA}APA style in the so|-|named rendering. Yet be warned that very
+few editors and publishers in fact follow this style exactly so some
+customization will always be required.
+\stopaside
+
+In addition to the APA specification, there are many prescribed styles to render
+bibliographic descriptions that can be programmed as standards. Alternatives to
+\index {style+APA}\TEXcode {specification=apa} might be \index
+{style+MLA}\TEXcode {mla}, \index {style+Chicago}\TEXcode {chicago}, \index
+{style+Harvard}\TEXcode {harvard}, \index {style+IEEE}\TEXcode {ieee}, \index
+{style+APS}\TEXcode {aps} (commonly used in the physical sciences), \index
+{style+Vancouver}\TEXcode {vancouver} (used in the biological sciences), or many
+others. At this time, we only provide two description files, with \index
+{style+APS}\TEXcode {aps} being an example\startfootnote The \index
+{style+APS}APS style attempts to be very compact, providing complete yet minimal
+information, in contrast to the \index {style+APA}APA style which is rather
+verbose. \stopfootnote of a number|-|based rather than an authoryear|-|based
+scheme; more style schemes may be added in the future and the customization of a
+rendering style will be described in a later chapter.
+
+The rendering style usually also implies a particular bibliography list \Index
+{sorting} scheme as well as the use of a particular citation style. Indeed, the
+rendering of bibliography lists and references to it are intimately coupled. This
+question will be explained a bit later. The \index {style+APA}APA style, for
+example, specifies that the bibliography list be sorted by author and then by
+year, then by title. The list is not numbered (references are cited by author and
+year). Note, however, as can be seen from the two examples shown above that the
+references were indeed assigned numbers even though they are not displayed in the
+\index {style+APA}\TEXcode {apa} rendering (the user can easily choose to display
+these numbers, if desired).
+
+\stopsection
+
+\startsection
+  [list={Bibliography list scope},
+   title={Bibliography list \Index{scope}}]
+
+A single dataset can by used with multiple renderings. Although these renderings
+may illustrate different styles (as here for the purpose of demonstration in a
+manual on bibliographies), this would not be a coherent choice for a document
+that would normally employ a single bibliography style.
+
+The most obvious use of multiple renderings (employing a single specification) is
+the placement of bibliography lists localized by structure elements: parts,
+chapters in a book, sections, etc. through the option \TEXcode
+{criterium=chapter}, for example. This can be setup using:
+
+\cindex{setupbtxrendering}
+
+\startTEX
+\setupbtxrendering
+    [default]
+    [repeat=yes,
+     continue=yes,
+     method=global]
+\stopTEX
+
+followed at the end of each chapter by
+
+\cindex{placelistofpublications}
+
+\startTEX
+\placelistofpublications
+    [criterium=chapter]
+\stopTEX
+
+The numbering might alternately be made local through the option \TEXcode
+{method=local}. If desired, the reference numbers can also get prefixed:
+
+\cindex{setupbtxlist}
+
+\startTEX
+\setupbtxlist
+    [default]
+    [prefix=yes,
+     width=1cm]
+\stopTEX
+
+A bibliography list rendering placed at a single location, at the end of a book,
+for example, can also be easily split into structural parts. The following code
+(given without any explanation) illustrates this idea nicely:
+
+\cindex{placelistofpublications}
+
+\startTEX
+\startbackmatter
+    \startchapter [title=Bibliography,number=no,incrementnumber=no]
+        \startsubject [title=Introduction]
+            \placelistofpublications
+                [criterium=reference,reference=introduction]
+        \stopsubject
+        \dorecurse{12} {
+            \startsubject [title={Chapter #1}]
+                \placelistofpublications
+                    [criterium=bodypart:chapter,reference=#1]
+            \stopsubject
+        }
+    \stopchapter
+\stopbackmatter
+\stopTEX
+
+Note, as the above demonstrates, that the list of bibliography citations for
+\emphasis {any} referenced structural element can be placed \emphasis {anywhere}
+in the document, not simply within the structural element itself.

+Bibliography lists (and citations in the text, see below) are rendered in the
+language of the document (\Cindex {mainlanguage}). However, a bibliography entry
+can contain a \TEXcode {language=} field and this can be used (if present),
+depending on the specification, in the rendering and hyphenation of the \TEXcode
+{title}, for example.
+
+One might choose to override this behavior and impose a single language for all
+bibliography entries (as well as for all other \CONTEXT\ constructs) using
+\Cindex {setupdelimitedtext} \TEXcode {[language=global]}.
+
+Since this directive is general for all delimited text in \CONTEXT\ and is not
+specific to bibliographies, one can apply it to force a particular language
+within a unique section, as in:
+
+\cindex{setupdelimitedtext}
+\cindex{placelistofpublications}
+
+\startTEX
+\startsection[title=Bibliografía]
+    \setupdelimitedtext[language=es]
+    \placelistofpublications
+\stopsection
+\stopTEX
+
+% to Hans: This currently does not work!
+% to Alan: I need an example!
+
+The language setting also influences the sorting of \UTF\ strings, in particular
+authors and titles.
+
+\cindex   {setupdelimitedtext}
+\showsetup[setupdelimitedtext]
+
+\startplacetable [title={\cindex{setupdelimitedtext}\TEXcode{\setupdelimitedtext[language=…]}}]
+    \starttabulate [|Tl|p(.7\textwidth)|]
+        \NC language= \NC \NC \NR
+        \HL
+        \NC {\it<blank>} \NC (the default) use the current active language; \NC \NR
+        \NC local        \NC respect local language directives (such as the
+                             entry's \TEXcode {language={…},} field, if present
+                             and managed by the rendering specification) \NC \NR
+        \NC global       \NC impose the main document language; \NC \NR
+        \NC en, de, nl,
+            \unknown     \NC impose the specified language. \NC \NR
+        \HL
+    \stoptabulate
+\stopplacetable
+
+\startsubsubject[title=Translated titles]
+
+Going beyond this handling of punctuation, labels and sorting, we have also
+introduced an entirely new feature, allowing for dataset entries to contain
+fields describing translated titles, for example. This is particularly useful
+when including citations to references published in languages other than the
+document language.
+
+Below is an example including \emphasis{three} languages: \startfootnote In this
+reference, the \TEXcode {title} and the \TEXcode {booktitle} are in different
+languages and the \TEXcode {language = {french},} field refers to the cited text.
+Both titles would have been rendered using French hyphenation rules had this not
+been overridden by including the switch \TEXcode {\de} that otherwise should be
+avoided in a database. The solution used here is sloppy, but fortunately, a
+complicated situation such as this is not very common.
+\stopfootnote
+
+% We could have
+%   booktitle:de = {Die ...},
+%
+% but what simple logic could be used to indicate choosing this title?
+% The present case could, perhaps should, have language = {german}, but this
+% would simply switch the problem to title = {\fr Principes ...},

+% \enabletrackers[typesetters.periodkerns]
+
+When you use so called non french spacing you get more spacing after punctuation
+(as determined by the \type {sfcode} of the punctuation character) . However,
+when you use periods as delimiters for abbreviations, that period is not the end
+of a sentence and you want normal interword spacing instead. One way to achieve
+this is to add a backslash after the period but in an automated workflow where
+the source is not coming from \TEX\ but for instance in \XML\ format, you can't
+do that. The \type {\setupspacing} command can be used to set one of:
+
+\starttabulate[|T|p|]
+\NC fixed  \NC \showglyphs \frenchspacing    bla bla e.g. some more \NC \NR
+\NC packed \NC \showglyphs \newfrenchspacing bla bla e.g. some more \NC \NR
+\NC broad  \NC \showglyphs \nonfrenchspacing bla bla e.g. some more \NC \NR
+\stoptabulate
+
+The \type {packed} case is similar to \type {fixed} but has slightly larger (some
+5\percent) spacing after punctuation which (at least historically) avoids some
+side effects with hyphenation and dashes. We default to \type {broad} anyway.
+
+The next examples demonstrate what the \type {\setperiodkerning} does when it gets
+an option passed. Its counterpart is \type {\resetperiodkerning}.

+When \TEX\ reads its input and transforms content it into a node list spaces are
+turned into glue nodes of subtype \quote {spaceskip} or \quote {xspaceskip}. In
+pseudo code, this is what happens:
+
+\starttyping
+if spacefactor >= 2000 and xspaceskip ~= 0 then
+    space   = xspaceskip_space
+    stretch = xspaceskip_stretch
+    shrink  = xspaceskip_shrink
+    subtype = xspaceskip
+else
+    if spaceskip == 0 then
+        space   = font_space
+        stretch = font_stretch
+        shrink  = font_shrink
+    else
+        space   = spaceskip_space
+        stretch = spaceskip_stretch
+        shrink  = spaceskip_shrink
+    end
+    if space_factor >= 2000
+        space = space + font_extraspace
+    end
+    stretch = stretch * space_factor
+    shrink  = shrink  * space_factor
+    subtype = spaceskip
+end
+insert_glue(space,stretch,shrink,subtype)
+\stoptyping
+
+We demonstrate the effects in a few examples. You can use \typ {\showmakeup [space]} to
+visualize spaces.

+The width of a space relates to the design of a font and therefore the t width of
+the space, its stretch and its shrink are taken from the font and scaled
+accordingly. Normally we take the space character in the font as reference.
+Traditional \TEX\ fonts don't have that character but \OPENTYPE\ fonts have. When
+there is no space character, in the case of a monospaced font we take the
+emwidth, otherwise we take half the emwidth. As a last resort we can take the
+average width of characters. And of even that fails we take half of the font
+units. But, as mentioned, modern fonts have a space.
+
+In the \CONTEXT\ font loader we use a stretch that is 1/2 of the width of a space
+and the shrink is 1/3 the width of a space. These values are familiar for those
+who come from traditional \TEX.
+
+As with many variables, you can overload these values when a font is loaded by
+setting the \type {spacing} feature. Here is how this is done:
+
+\startbuffer
+\definefontfeature
+  [morespace]
+  [spacing=0.50 plus 0.50 minus 0.250]
+\definefontfeature
+  [lessspace]
+  [spacing=0.25 plus 0.25 minus 0.125]
+\definefontfeature
+  [extramorespace]
+  [spacing=0.50 plus 0.50 minus 0.250 extra 2.00]
+\definefontfeature
+  [extralessspace]
+  [spacing=0.25 plus 0.25 minus 0.125 extra 2.00]
+

+
+For demonstration purposes we use a somewhat excessive \type {extra}
+specification. By default the extra space is equal to the shrink.

+\startsection[title=Expansion]
+
+Spaces become glue that can shrink or stretch. In the worst case words will come
+too close, or the gap will be large. Even worse is that this can lead to
+successive lines in a paragraph looking different with respect to spacing. A solution
+for this is to use font expansion, although the benefits are often less than
+some users want (you) to believe.
+
+This mechanism is enabled with \type {\setupalign}. There are two variants (\type
+{hz} and \type {fullhz}) and a reset (\type {nohz}). In \in {figure} [fig:expansion]
+we use the following font definition:
+
+\startbuffer
+\definefont[testfont][Normal*default,quality @ 9pt]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+We use \type {\showfontexpansion} to view the effective expansion factors of each
+glyph. When \type {fullhz} is used fontkerns also can get expanded. Zero values
+are not shown. The font kern factors are shown below the character factors. They
+can be neglected and one can even wonder if they need a treatment especially
+because kerns are also used for relative positioning, accent anchoring and
+cursive attachments.

+\startsection[title=Looseness]
+
+The \type {\looseness} parameter can be used to let the par builder add more
+lines, but that condition is only met when the demand is reasonable. So we need
+stretch and often also tolerance to achieve it.
+
+\starttyping
+\looseness=1 ... text ... \par
+\stoptyping
+
+This setting is reset afterwards. Because \type {framed} does some grouping deep down,
+we need either to use it in there like this:
+
+\starttyping
+\framed
+  [align={normal,verytolerant,stretch},strut=no]
+  {\looseness1 ... \par}
+\stoptyping
+
+which is somewhat clumsy, or we can do:
+
+\starttyping
+\framed
+  [align={normal,verytolerant,stretch,2*more}]
+  {...}
+\stoptyping

+This is demonstrated in \in {figure} [fig:looseness].

+\startsection[title={Errors}]
+
+A \CONTEXT\ runs normally spits out quite some information to the console. In
+fact, even more information can go to the log file. It makes sense to have a look
+at the end of the log file occasionally because there you can find information
+about the (file) structure loaded, modules, issues with references and|/|or
+fonts, etc.
+
+One problem with the terminal is that you can miss an issue easily, but there is
+a way out of this:
+
+\starttyping
+\enabledirectives[logs.errors]
+\stoptyping
+
+The command line argument \type {--errors} has the same consequence. If you want
+to quit in an error, you can say for instance:
+
+\starttyping
+\enabledirectives[logs.errors=missing characters]
+\stoptyping
+
+If you run \CONTEXT\ with \type {--trackers} or \type {--directives} you get some
+information about the possible extra tracing. It might be illustrative to run a
+file with:
+
+\starttyping
+\enabletrackers[*]
+\stoptyping
+
+There are all kind of trackers and directives and you can get a list with:
+
+\starttyping
+context --trackers --directives
+\stoptyping
+
+An example is:
+
+\starttyping
+\enabletrackers[fonts.missing=replace]
+\stoptyping
+
+or just:
+
+\starttyping
+\enabletrackers[fonts.missing]
+\stoptyping
+
+
+\stopsection
+
+\startsection[title={Silent}]
+
+The \type {--silent} options blocks most message. You can also pass a list (or

+logging to the console. The error reporting mentioned in the previous section
+will never be silenced.

+\startchapter[title=\SYNCTEX]
+
+\startsection[title=Introduction]
+
+Some users like the \SYNCTEX\ feature that is built in the \TEX\ engines.
+Personally I never use it because it doesn't work well with the kind of documents
+I maintain. If you have one document source, and don't shuffle around (reuse)
+text too much it probably works out okay but that is not our practice. Here I
+will describe how you can enable a more \CONTEXT\ specific \SYNCTEX\ support so
+that aware \PDF\ viewers can bring you back to the source.
+
+\stopsection
+
+\startsection[title=What we want]
+
+The \SYNCTEX\ method roughly works as follows. Internally \TEX\ constricts linked
+lists of glyphs, kerns, glue, boxes, rules etc. These elements are called nodes.
+Some nodes carry information about the file and line where they were created. In
+the backend this information gets somehow translated in a (sort of) verbose tree
+that describes the makeup in terms of boxes, glue and kerns. From that
+information the \SYNCTEX\ parser library, hooked into a \PDF\ viewer, can go back
+from a position on the screen to a line in a file. One would expect this to be a
+relative simple rectangle based model, but as far as I can see it's way more
+complex than that. There are some comments that \CONTEXT\ is not supported well
+because it has a layered page model, which indicates that there are some
+assumptions about how macro packages are supposed to work. Also the used
+heuristics not only involve some specific spot (location) but also involve the
+corners and edges. It is therefore not so much a (simple) generic system but a
+mechanism geared for a macro package like \LATEX.
+
+Because we have a couple of users who need to edit complex sets of documents,
+coded in \TEX\ or \XML, I decided to come up with a variant that doesn't use the
+\SYNCTEX\ machinery but manipulates the few \SYNCTEX\ fields directly \footnote {This
+is something that in my opinion should have been possible right from the start
+but it's too late now to change the system and it would not be used beyond
+\CONTEXT\ anyway.} and eventually outputs a straightforward file for the editor.
+Of course we need to follow some rules so that the editor can deal with it. It
+took a bit of trial and error to get the right information in the support file
+needed by the viewer but we got there.
+
+The prerequisites of a decent \CONTEXT\ \quotation {click on preview and goto
+editor} are the following:
+
+\startitemize
+
+\startitem
+    It only makes sense to click on text in the text flow. Headers and footers
+    are often generated from structure, and special typographic elements can
+    originate in macros hooked into commands instead of in the source.
+\stopitem
+
+\startitem
+    Users should not be able to reach environments (styles) and other files
+    loaded from the (normally read|-|only) \TEX\ tree, like modules. We don't
+    want accidental changes in such files.
+\stopitem
+
+\startitem
+    We not only have \TEX\ files but also \XML\ files and these can normally
+    flush in rather arbitrary ways. Although the concept of lines is sort of
+    lost in such a file, there is still a relation between lines and the snippets
+    that make out the content of an \XML\ node.
+\stopitem
+
+\startitem
+    In the case of \XML\ files the overhead related to preserving line
+    numbers should be minimal and have no impact on loading and memory when
+    these features are not used.
+\stopitem
+
+\startitem
+    The overhead in terms of an auxiliary file size and complexity as well
+    as producing that file should be minimal. It should be easy to turn on and
+    off these features. (I'd never turn them on by default.)
+\stopitem
+
+\stopitemize
+
+It is unavoidable that we get more run time but I assume that for the average user
+that is no big deal. It pays off when you have a workflow when a book (or even a
+chapter in a book) is generated from hundreds of small \XML\ files. There is no
+overhead when \SYNCTEX\ is not used.
+
+In \CONTEXT\ we don't use the built|-|in \SYNCTEX\ features, that is: we let
+filename and line numbers be set but often these are overloaded explicitly. The
+output file is not compressed and constructed by \CONTEXT. There is no benefit in
+compression and the files are probably smaller than default \SYNCTEX\ anyway.
+
+\stopsection
+
+\startsection[title=Commands]
+
+Although you can enable this mechanism with directives it makes sense to do it
+using the following command.
+
+\starttyping
+\setupsynctex[state=start]
+\stoptyping
+
+The advantage of using an explicit command instead of some command line option is
+that in an editor it's easier to disable this trickery. Commenting that line will
+speed up processing when needed. This command can also be given in an environment
+(style). On the command line you can say
+
+\starttyping
+context --synctex somefile.tex
+\stoptyping
+
+A third method is to put this at the top of your file:
+
+\starttyping
+% synctex=yes
+\stoptyping
+
+Often an \XML\ files is very structured and although probably the main body of
+text is flushed as a stream, specific elements can be flushed out of order. In
+educational documents flushing for instance answers to exercises can happen out of
+order. In that case we still need to make sure that we go to the right spot in
+the file. It will never be 100\% perfect but it's better than nothing. The
+above command will also enable \XML\ support.
+
+If you don't want a file to be accessed, you can block it:
+
+\starttyping
+\blocksynctexfile[foo.tex]
+\stoptyping
+
+Of course you need to configure the viewer to respond to the request for
+editing. In Sumatra combined with SciTE the magic command is:
+
+\starttyping
+c:\data\system\scite\wscite\scite.exe "%f" "-goto:%l"
+\stoptyping
+
+Such a command is independent of the macro package so you can just consult the
+manual or help info that comes with a viewer, given that it supports this linking
+back to the source at all.
+
+\stopsection
+
+\startsection[title=Methods]
+
+Contrary to the native \SYNCTEX\ we only deal with text which gives reasonable
+efficient output. If you enable tracing (see next section) you can what has
+become clickable. Instead of words you can also work with ranges, which not only
+gives less runtime but also much smaller \type {.synctex} files. Just try:
+
+\starttyping
+\setupsynctex[state=start,method=min]
+\stoptyping
+
+to get words clickable and
+
+\starttyping
+\setupsynctex[state=start,method=max]
+\stoptyping
+
+to get the more efficient ranges. The overhead for \type {min} is some 10 percent
+while \type {max} slows down around 5 percent.
+
+\stopsection
+
+\startsection[title=Tracing]
+
+In case you want to see what gets synced you can enable a tracker:
+
+\starttyping
+\enabletrackers[system.synctex.visualize]
+\enabletrackers[system.synctex.visualize=real]
+\stoptyping
+
+The following tracker outputs some status information about \XML\ flushing. Such
+trackers only make sense for developers.
+
+\starttyping
+\enabletrackers[system.synctex.xml]
+\stoptyping
+
+% At the cost of some extra overhead, the next (experimental) directive can be used
+% when the accuracy is not optimal.
+%
+% \starttyping
+% \enabledirectives[system.synctex.details]
+% \stoptyping
+
+\stopsection
+
+\startsection[title=Warning]
+
+Don't turn on this feature when you don't need it. This is one of those mechanism
+that hits performance badly.
+
+Depending on needs the functionality can be improved and|/|or extended. Of course
+you can always use the traditional \SYNCTEX\ method but don't expect it to behave
+as described here.

+%D Embedding (and using) movies used to be a breeze in acrobat but depended
+%D on a plugin. Then we got renditions that depended on the built-in flash
+%D player. And now we have rich media, depending on whatever and being able
+%D to use the flash player as well ... but it's an erratic and soon obsolete
+%D adventure. So \unknown\ we do provide the user the means but stay away
+%D from it ourselves: it's a dead end. The following tricks use the already
+%D present shockwave (flash) trickery.
+%D

+%D runtime.

--- One day I'll speed this up ... char swapping and properties.
-
--- A few remarks:
---
--- This code is a partial rewrite of the code that deals with devanagari. The data and logic
--- is by Kai Eigner and based based on Microsoft's OpenType specifications for specific
--- scripts, but with a few improvements. More information can be found at:
---
--- deva: http://www.microsoft.com/typography/OpenType%20Dev/devanagari/introO.mspx
--- dev2: http://www.microsoft.com/typography/OpenType%20Dev/devanagari/intro.mspx
---
--- Rajeesh Nambiar provided patches for the malayalam variant. Thansk to feedback from
--- the mailing list some aspects could be improved.
---
--- As I touched nearly all code, reshuffled it, optimized a lot, etc. etc. (imagine how
--- much can get messed up in over a week work) it could be that I introduced bugs. There
--- is more to gain (esp in the functions applied to a range) but I'll do that when
--- everything works as expected. Kai's original code is kept in font-odk.lua as a reference
--- so blame me (HH) for bugs.
---
--- Interesting is that Kai managed to write this on top of the existing otf handler. Only a
--- few extensions were needed, like a few more analyzing states and dealing with changed
--- head nodes in the core scanner as that only happens here. There's a lot going on here
--- and it's only because I touched nearly all code that I got a bit of a picture of what
--- happens. For in-depth knowledge one needs to consult Kai.
---
--- The rewrite mostly deals with efficiency, both in terms of speed and code. We also made
--- sure that it suits generic use as well as use in ConTeXt. I removed some buglets but can
--- as well have messed up the logic by doing this. For this we keep the original around
--- as that serves as reference. Due to the lots of reshuffling glyphs quite some leaks
--- occur(red) but once I'm satisfied with the rewrite I'll weed them. I also integrated
--- initialization etc into the regular mechanisms.
---
--- In the meantime, we're down from 25.5-3.5=22 seconds to 17.7-3.5=14.2 seconds for a 100
--- page sample (mid 2012) with both variants so it's worth the effort. Some more speedup is
--- to be expected. Due to the method chosen it will never be real fast. If I ever become a
--- power user I'll have a go at some further speed up. I will rename some functions (and
--- features) once we don't need to check the original code. We now use a special subset
--- sequence for use inside the analyzer (after all we could can store this in the dataset
--- and save redundant analysis).
---
--- I might go for an array approach with respect to attributes (and reshuffling). Easier.
---
--- Some data will move to char-def.lua (some day).
---
--- Hans Hagen, PRAGMA-ADE, Hasselt NL
---
--- We could have c_nukta, c_halant, c_ra is we know that they are never used mixed within
--- one script .. yes or no?
---
--- Matras: according to Microsoft typography specifications "up to one of each type:
--- pre-, above-, below- or post- base", but that does not seem to be right. It could
--- become an option.
---
--- The next code looks weird anyway: the "and boolean" should move inside the if
--- or we should check differently (case vs successive).

--- todo: way more caching of attributes and font
-
--- Reph’s original position is always at the beginning of the syllable, (i.e. it is not reordered at the character reordering stage).
--- However, it will be reordered according to the basic-forms shaping results.
--- Possible positions for reph, depending on the script, are; after main, before post-base consonant forms,
--- and after post-base consonant forms.
-
--- 1  If reph should be positioned after post-base consonant forms, proceed to step 5.
--- 2  If the reph repositioning class is not after post-base: target position is after the first explicit halant glyph between
---    the first post-reph consonant and last main consonant. If ZWJ or ZWNJ are following this halant, position is moved after it.
---    If such position is found, this is the target position. Otherwise, proceed to the next step.
---    Note: in old-implementation fonts, where classifications were fixed in shaping engine,
---    there was no case where reph position will be found on this step.
--- 3  If reph should be repositioned after the main consonant: from the first consonant not ligated with main,
---    or find the first consonant that is not a potential pre-base reordering Ra.
--- 4  If reph should be positioned before post-base consonant, find first post-base classified consonant not ligated with main.
---    If no consonant is found, the target position should be before the first matra, syllable modifier sign or vedic sign.
--- 5  If no consonant is found in steps 3 or 4, move reph to a position immediately before the first post-base matra,
---    syllable modifier sign or vedic sign that has a reordering class after the intended reph position.
---    For example, if the reordering position for reph is post-main, it will skip above-base matras that also have a post-main position.
--- 6  Otherwise, reorder reph to the end of the syllable.

--- The original basemode ligature builder used the names of components
--- and did some expression juggling to get the chain right. The current
--- variant starts with unicodes but still uses names to make the chain.
--- This is needed because we have to create intermediates when needed
--- but use predefined snippets when available. To some extend the
--- current builder is more stupid but I don't worry that much about it
--- as ligatures are rather predicatable.
---
--- Personally I think that an ff + i == ffi rule as used in for instance
--- latin modern is pretty weird as no sane person will key that in and
--- expect a glyph for that ligature plus the following character. Anyhow,
--- as we need to deal with this, we do, but no guarantes are given.

---
--- The while loop is needed because we need to resolve for instance

---[[ldx--
-<p>This module is a bit more split up that I'd like but since we also want to test
-with plain <l n='tex'/> it has to be so. This module is part of <l n='context'/>
-and discussion about improvements and functionality mostly happens on the
-<l n='context'/> mailing list.</p>
-
-<p>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.</p>
-
-<p>Because there is so much possible, fonts might contain bugs and/or be made to
-work with certain rederers. These may evolve over time which may have the side
-effect that suddenly fonts behave differently.</p>
-
-<p>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 optimizations 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 <l n='context'/> users ask for it.</p>
-
-<p>The specification leaves room for interpretation. In case of doubt the microsoft
-implementation is the reference as it is the most complete one. As they deal with
-lots of scripts and fonts, Kai and Ivo did a lot of testing of the generic code and
-their suggestions help improve the code. I'm aware that not all border cases can be
-taken care of, unless we accept excessive runtime, and even then the interference
-with other mechanisms (like hyphenation) are not trivial.</p>
-
-<p>Glyphs are indexed not by unicode but in their own way. This is because there is no
-relationship with unicode at all, apart from the fact that a font might cover certain
-ranges of characters. One character can have multiple shapes. However, at the
-<l n='tex'/> end we use unicode so and all extra glyphs are mapped into a private
-space. This is needed because we need to access them and <l n='tex'/> has to include
-then in the output eventually.</p>
-
-<p>The raw table as it coms from <l n='fontforge'/> gets reorganized in to fit out needs.
-In <l n='context'/> that table is packed (similar tables are shared) and cached on disk
-so that successive runs can use the optimized table (after loading the table is
-unpacked). The flattening code used later is a prelude to an even more compact table
-format (and as such it keeps evolving).</p>
-
-<p>This module is sparsely documented because it is a moving target. The table format
-of the reader changes and we experiment a lot with different methods for supporting
-features.</p>
-
-<p>As with the <l n='afm'/> code, we may decide to store more information in the
-<l n='otf'/> table.</p>
-
-<p>Incrementing the version number will force a re-cache. We jump the number by one
-when there's a fix in the <l n='fontforge'/> library or <l n='lua'/> code that
-results in different tables.</p>

--- A previous version had disc collapsing code in the (single sub) handler plus some
--- checking in the main loop, but that left the pre/post sequences undone. The best
--- solution is to add some checking there and backtrack when a replace/post matches
--- but it takes a bit of work to figure out an efficient way (this is what the sweep*
--- names refer to). I might look into that variant one day again as it can replace
--- some other code too. In that approach we can have a special version for gub and pos
--- which gains some speed. This method does the test and passes info to the handlers
--- (sweepnode, sweepmode, sweepprev, sweepnext, etc). Here collapsing is handled in the
--- main loop which also makes code elsewhere simpler (i.e. no need for the other special
--- runners and disc code in ligature building). I also experimented with pushing preceding
--- glyphs sequences in the replace/pre fields beforehand which saves checking afterwards
--- but at the cost of duplicate glyphs (memory) but it's too much overhead (runtime).
---
--- In the meantime Kai had moved the code from the single chain into a more general handler
--- and this one (renamed to chaindisk) is used now. I optimized the code a bit and brought
--- it in sycn with the other code. Hopefully I didn't introduce errors. Note: this somewhat
--- complex approach is meant for fonts that implement (for instance) ligatures by character
--- replacement which to some extend is not that suitable for hyphenation. I also use some
--- helpers. This method passes some states but reparses the list. There is room for a bit of
--- speed up but that will be done in the context version. (In fact a partial rewrite of all
--- code can bring some more efficientry.)
---
--- I didn't test it with extremes but successive disc nodes still can give issues but in
--- order to handle that we need more complex code which also slows down even more. The main
--- loop variant could deal with that: test, collapse, backtrack.

+-- obsolete too or at least they are bound to the (obsolete) flash technology for
+-- rendering. They were already complex constructs. Now we have rich media which

+-- again seems to depend on viewers built in (yes, also kind of obsolete) flash
+-- technology, and we cannot expect this non-open technology to show up in open
+-- browsers. So, in the end we can best just use links to external resources to be
+-- future proof. Just look at the viewer prferences pane to see how fragile support
+-- is. Interestingly u3d support is kind of built in, while e.g. mp4 support relies
+-- on wrapping in swf. We used to stay ahead of the pack with support of the fancy
+-- pdf features but it backfires and is not worth the trouble. And yes, for control
+-- (even simple like starting and stopping videos) one has to revert to JavaScript,
+-- the other fragile bit. And, now that adobe quits flash in 2020 we're without any
+-- video anyway. Also, it won't play on all platforms and devices so let's wait for

+%D fails with: \type{Misplaced alignment tab character &} and here is the
+%D reason.
+%D
+%D When we have a letter or other category a check happens for an active
+%D character and when it has one then it gets expanded and fed back into the
+%D scanner (sort of).
+%D
+%D A \type {\char} is also fed back as raw character and again when it's letter
+%D of other goes through the same process.
+%D
+%D This means that we cannot have a definition like:
+%D
+%D \starttyping
+%D \def\AND{\char"26\relax}
+%D \stoptyping
+%D
+%D that can be used in math mode, which is why the cweb macros do:
+%D
+%D \starttyping
+%D \def\AND{\def\AND{\mathchar"2026\relax}\AND}
+%D \stoptyping
+%D
+%D Maybe we need an option to treat chars like chars.

+%D This module provides a simple \TEX\ layer on top of the nodes library that
+%D is preloaded in \METAFUN. More information can be found in the manual and
+%D article.
+%D
+%D We strongly advice to use the \METAPOST\ interface and only provide this
+%D \TEX\ variant as proof of concept. There are no plans to extend this module
+%D because we see no advantage in using a \TEX\ interface over a \METAPOST\
+%D one.

+%D In case one wonders what domotica has to do with ConTeXt, here is the short
+%D story. One day I'll wrap up a long one.
+%D
+%D After years of keeping an eye on developments and techniques and being somewhat
+%D disappointed by experiments, I decided to settle on a local approach for simple
+%D domotica (criteria are: stability, full open source, decent scripting, future
+%D safe). Eventually I decides to buy a few (overpriced) hue zigbee hubs: one
+%D private and one for the office, so that I could create different lightning
+%D setups, automatically control light to be turned on and off, etc. Unfortunately
+%D those hubs are rather limited in functionality and performance, which is
+%D surprising for an otherwise mature product. So (we're speaking mid 2015) I wrote
+%D a couple of scripts in \LUA\ that would do the real magic, and only use the hub
+%D for controlling the individual lights, buttons and sensors. That way I could
+%D create complex arrangements (think of setups for working, reading, talking,
+%D either of not in parts or rooms) driven by the available buttons and motion
+%D sensors. I really needed multiple sensors and buttons per room, something (again
+%D surprisingly) not supported by the hub at that time. It seems that more than a
+%D year later functionality that I needed and wrote gets added stepwise to the hub:
+%D multiple sensors, multiple use of buttons, etc. Compared to free \TEX\
+%D developments such commercial products evolve slow.
+%D
+%D In addition to these hubs I bought some zwave devices for controlling heating and
+%D a few rf radio things for sunshades. For zwave I uses the same approach: buy a
+%D decent hub (the nice popp hub) and control it via \LUA. In fact, I can now use
+%D one set of scripts to control a mix of technologies. However, when programming
+%D the lot, one needs to have an overview of devices and that is where this module
+%D comes into view. In fact, \LUATEX\ was already in view as I wrote the scripts in
+%D \LUA, using the \CONTEXT\ helper libraries. And the lots runs on a small low
+%D power (<10W) fitlet using stock \LUATEX\ as \LUA\ engine.

+%D constants and variables. When \CONTEXT\ grew bigger and bigger in terms of bytes
+%D and used string space, we switched to predefined constants. At the cost of more
+%D hash table entries, the macros not only becase more compact, they became much
+%D faster too. Maybe an even bigger advantage was that mispelling could no longer
+%D lead to problems. Even a multi||lingual interface became possible.

+-- more complex situations like included xml files. Currently (somewhere else) we
+-- take care of valid files, that is: we prohibit access to files in the tree
+-- because we don't want users to mess up styles.

+-- It is unclear how the output gets interpreted but by reverse engineering (and
+-- stripping) the file generated by generic synctex, I got there eventually. For
+-- instance, we only need to be able to go back to a place where text is entered,
+-- but still we need all that redundant box wrapping. Anyway, I was able to get a
+-- minimal output and cross my fingers that the parser used in editors is not
+-- changed in fundamental ways.
 --
--- Possible optimizations: pack whole lines.
+-- I only tested SumatraPDF with SciTE, for which one needs to configure in the
+-- viewer:
+--
+-- InverseSearchCmdLine = c:\data\system\scite\wscite\scite.exe "%f" "-goto:%l" $
+--
+-- Unfortunately syntex always removes the files at the end and not at the start
+-- (this happens in synctexterminate) so we need to work around that by using an
+-- intermediate file. This is no big deal in context (which has a runner) but
+-- definitely not nice.
+--
+-- The visualizer code is only needed for testing so we don't use fancy colors or
+-- provide more detail. After all we're only interested in rendered source text
+-- anyway. We try to play safe which sometimes means that we'd better no go
+-- somewhere than go someplace wrong.
+--
+-- A previous version had a mode for exporting boxes and such but I removed that
+-- as it made no sense. Also, collecting output in a table was not faster than
+-- directly piping to the file, probably because the amount is not that large. We
+-- keep some left-overs commented.
+--
+-- A significate reduction in file size can be realized when reusing the same
+-- values. Actually that triggered the current approach in ConTeXt. In the latest
+-- synctex parser vertical positions can be repeated by an "=" sign but for some
+-- reason only for that field. It's probably trivial to do that for all of "w h d v
+-- h" but it currently not the case so I'll delay that till all are supported. (We
+-- could benefit a lot from such a repetition scheme but not much from a "v" alone
+-- which -alas- indicates that synctex is still mostly a latex targeted story.)
+--
+-- It's kind of hard to fight the parser because it really wants to go to some file
+-- but maybe some day I can figure it out. Some untagged text (in the pdf) somehow
+-- gets seen as part of the last box. Anonymous content is simply not part of the
+-- concept. Using a dummy name doesn't help either as the editor gets a signal to
+-- open that dummy. Even an empty filename doesn't work.

+%D This is very experimental code! We took a bit from the mixed columns and single
+%D column page code. This one works acceptable with floats and is for whole double
+%D column documents. We don't balance (yet). Footnotes are per column. One can have
+%D side floats too. No balancing and other fancy features.
+%D
+%D Don't use this in production! Although the main approach will stay there might be
+%D changes in the way floats are dealt with. Not much testing has been done but as
+%D we stay close to the single column mode we expect most to just work. Only floats
+%D are the (usual) pain. Backgrounds, line numbering, etc.\ not tested either.

+%D These macro deal with side floats. We started with Daniel Comenetz macros as
+%D published in TUGBoat Volume 14 (1993), No.\ 1: Anchored Figures at Either Margin.
+%D I extended and patched the macros to suite our needs which results in a messy
+%D module.
+%D
+%D A complication is that we need to deal with spacing differently before and after
+%D the float. Also, whitespace can interfere as does the prevdepth. There is no real
+%D universal solution. So, by now not much is left of that code, if only because we
+%D need to match \CONTEXT\ spacing module, because we have more placement options
+%D and control and because the math hackery is not suitable for \CONTEXT\ anyway.
+%D
+%D This code had been redone many times because we kept running into spacing issues
+%D and it's not that much fun (or rewarding). It's probably the module that made
+%D me go into distraciton mode most often (like watching amusing Walk of The
+%D Earth, sophisticated Massive Attack video clips, impressive Davie504 movies
+%D and so on).

+-- alas ... pdf has lost the battle with html here due to a few decades of
+-- unstability and changing support. So far we could catch on and even were ahead

-    \startitem currently the new namespace prefixes are not consistent but this
-               will be done when we're satisfied with one scheme \stopitem
-    \startitem there will be additional columns in the table, like for namespace
-               so we need another round of checking then \stopitem
-    \startitem the lua code will be cleaned up upgraded as some is quite old
-               and experimental \stopitem
-    \startitem we need a proper dependency tree and better defined loading order \stopitem
-    \startitem all dotag.. will be moved to the tags_.. namespace \stopitem
-    \startitem we need to check what messages are gone (i.e.\ clean up mult-mes) \stopitem
-    \startitem some commands can go from mult-def (and the xml file) \stopitem
-    \startitem check for setuphandler vs simplesetuphandler \stopitem
-    \startitem for the moment we will go for \type {xxxx_} namespaces that (mostly) match
-               the filename but later we can replace these by longer names (via a script) so
-               module writers should {\bf not} use the core commands with \type{_} in the
-               name \stopitem
-    \startitem the message system will be unified \stopitem
-    \startitem maybe rename dowhatevertexcommand to fromluawhatevertexcommand \stopitem
-    \startitem consider moving setups directly to lua end (e.g. in characterspacing, breakpoint, bitmaps etc.) \stopitem
-    \startitem more local temporary \type {\temp...} will become \type {\p_...} \stopitem
-    \startitem check all ctxlua calls for ctxcommand \stopitem
-    \startitem rename all those \type {\current<whatever>}s in strc \stopitem
-    \startitem check \type {option} vs \type {options} \stopitem
-    \startitem check \type {type} vs \type {kind} \stopitem
-    \startitem check \type {label} vs \type {name} vs \type {tag} \stopitem
-    \startitem check \type {limop}, different limops should should be classes \stopitem
-    \startitem too many positions in simple files (itemize etc) \stopitem
-    \startitem math domains/dictionaries \stopitem
-    \startitem xtables don't span vertically with multilines (yet) \stopitem
-    \startitem notes in mixed columns \stopitem
-    \startitem floats in mixed columns \stopitem
-    \startitem check return values \type {os.execute} \stopitem
-    \startitem more r, d, k in xml code \stopitem
-    \startitem mathml, more in \LUA \stopitem
-    \startitem style: font-size, font, color handling in \HTML\ (lxml-css) \stopitem
-    \startitem a \type {\name {A.B.C DEF}} auto-nobreakspace \stopitem
-    \startitem redo \CWEB\ module with \LUA \stopitem
-    \startitem maybe move characters.blocks to its own file \stopitem
-    \startitem more local context = context in \LUA\ files \stopitem
-    \startitem check and optimize all storage.register and locals (cosmetics) \stopitem
-    \startitem check all used modules in \LUA\ (and local them) \stopitem
-    \startitem environment and basic lua helpers are now spread over too many files \stopitem
-    \startitem isolate tracers and showers \stopitem
-    \startitem check all possible usage of ctxcommand \stopitem
-    \startitem there are more s-* modules, like s-fnt-41 \stopitem
-    \startitem check (un)marked tables \stopitem

+%D We used it to mark synonyms that should not be corrected by the editor. Sort of the
+%D reverse of not having a word in a vetted wordlist. A bit out of place in a typesetting
+%D system. If really needed we can support multiple words seperataed by spaces but I didn't
+%D need it. And \unknown\ fonts are supported but at fixed size!

 %D We have (currently) two modes: \type {text} and \type {number}. The handler tries
 %D to determine the mode automatically. When using periods and commas as separators
 %D the \type {number} mode is chosen. If you use for instance a \type {-} as
 %D separator, \type {text} is chosen, but you can enforce \type {number} with \type
-%D {number->-} (as with other mechanisms, the arrow indicates a methot to apply).

+-- When I needed a new boiler for heating I decided to replace a partial
+-- (experimental) zwave few-zone solution by the honeywell evohome system that can
+-- drive opentherm. I admit that I was not that satified beforehand with the fact
+-- that one has to go via some outside portal to communicate with the box but lets
+-- hope that this will change (I will experiment with the additional usb interface
+-- later). Anyway, apart from integrating it into my home automation setup so that I
+-- can add control based on someone present in a zone, I wanted to be able to render
+-- statistics. So that's why we have a module in ConTeXt for doing that. It's also
+-- an example of Lua and abusing LuaTeX for something not related to typesetting.
+--
+-- As with other scripts, it assumes that mtxrun is used so that we have the usual
+-- Lua libraries present.
+--
+-- The code is not that complex but figuring out the right request takes bit of
+-- searching the web. There is an api specification at:
+--
+--   https://developer.honeywell.com/api-methods?field_smart_method_tags_tid=All
+--
+-- Details like the application id can be found in several places. There are snippets
+-- of (often partial or old) code on the web but still one needs to experiment and
+-- combine information. We assume unique zone names and ids across gateways; I only
+-- have one installed anyway.
+--
+-- The original application was to just get the right information for generating
+-- statistics but in the meantime I also use this code to add additional functionality
+-- to the system, for instance switching between rooms (office, living room, attic) and
+-- absence for one or more rooms.

+
+    Right from the start the ConTeXt user interface was sytematic enough to be described using a
+    common framework. First it was done in the TeX language at the top of the files where features
+    were implemented. Later we switched to XML where all definitions were moved to one file. That
+    file could be translated to different user interfaces.
+
+    The current XML files are a follow up on this. Instead of one big file we now have many small
+    files, and support for shared (XML) definitions has been extended. Many more commands are defined,
+    including those considered low level. There are no longer translated files needed but you can
+    still generate them.
+
+    These files can be used to generate overviews (see x-setups-*.mkiv) but also for generating
+    information for text editors. We also use them for the (local) help service.

+%D This module is just for me when I wanted to check some husayni (by Idris)
+%D regression. Interesting is that fina should be disabled for hb (otherwise
+%D garbage) and that some substitutions are ignored in hb (1.1.3), so we can
+%D only compare some examples. Don't expect this style to be stable as I
+%D might change default features.

+% This is a sort of a check against xetex but with limited font trickery because we bypass
+% the normal font handling. It's no big deal for a test. The biggest problem is that we
+% run into default features and we don't know what is turned on by default. We also need
+% to disable tagging so that hb itself can do some (init/medi/fina) magic in setting
+% features.

+%D This is a rather old style, adn I used it for a presentation about \MATHML\
+%D around the turn of the century. Unfortunately I can't find back that weird
+%D presentation. I didn't change the code apart from loading the body font. One can
+%D clock on an area and get it large. Clicking elsewhere brings back the main page.

+%D         author=Aditya Mahajan,

+
+%D This file is derived from \filename{s-tug-02} written by Hans Hagen
+%D and Steve Grathwohl. Karl Berry asked me for some changes in the
+%D \TUGBOAT\ style files. The original file had an option of typesetting
+%D on a grid. That was too clever for me to understand, and hence to
+%D modify. Since \TUGBOAT\ usually does not typeset on a grid, I redid the
+%D style, borrowing parts from \filename{s-tug-02} and redoing some
+%D parts from scratch.
+
+%D \section Variables %<<<1
+%D
+%D We store the information about the article in variables.
+
+\setvariables
+  [tugboat]
+  [type=article,
+   columns=no,
+   grid=yes
+   ]

+
+%D \section Font Setup %<<<1
+%D 
+%D \TUGBOAT\ uses slightly different interline space than the default.
+%D So we change the interline space.
+
+\definebodyfontenvironment    [8pt] [interlinespace=9.5pt, big=9pt,  small=7pt]
+\definebodyfontenvironment    [9pt] [interlinespace=11pt, big=10pt,  small=8pt]
+\definebodyfontenvironment   [10pt] [interlinespace=12pt, big=12pt,  small=9pt]
+\definebodyfontenvironment   [12pt] [interlinespace=14pt,big=14.4pt,small=10pt]
+\definebodyfontenvironment [14.4pt] [interlinespace=18pt,big=14.4pt,small=12pt]
+\definebodyfontenvironment [9.8pt]  % Because 9.8pt is used in typing environments
+
+%D \TUGBOAT\ uses Computer Modern fonts, and \CONTEXT\ uses Latin Modern
+%D by default. So, we just specify the font size.
+
+\setupbodyfont [10pt]
+
+% Italic rather than slanted for emphasis.
+\setupbodyfontenvironment[default][em=italic]
+
+% Break after these chars in urls, not before.
+\sethyphenatedurlafter /
+\sethyphenatedurlafter .
+\sethyphenatedurlafter _
+
+%D \section Layout Setup %<<<1
+%D
+%D The original layout used in the \LATEX\ style for \TUGBOAT\ is a bit
+%D ambiguous. It uses low|-|level \TEX\ syntax, rather than changing the
+%D layout in a human understandable way (for example, by using the
+%D \mono{geometry} package. I have tried to translate it to \CONTEXT\ as
+%D far as I understand.
+
+\setuppapersize[letter][letter]
+
+\setuplayout
+  [topspace=3.8pc,% was 3.5pc
+   header=1pc,
+   headerdistance=1.5pc,
+   height=middle,
+   footerdistance=2pc,
+   footer=1pc,
+   bottomspace=3pc,
+   %
+   backspace=6pc,
+   width=middle,
+   cutspace=6pc,
+   %
+   margin=4pc,
+   margindistance=1pc,
+  ]
+
+\setupcolumns[distance=1.5pc]
+
+\setuppagenumbering
+  [location=,
+   alternative=doublesided]
+
+%D In \TUGBOAT\ different articles are glued together to form the final
+%D journal, so we do not want each article to occupy even number of
+%D pages.
+
+\installpagebreakhandler {last} {}
+
+%D \section Indentation %<<<1
+%D
+%D We use automatic indentation control, that is: no
+%D indentation after titles and skips.
+
+\setupindenting[20pt,yes]
+
+%D We do not want indentation after lists.
+
+\setupenumerations [indentnext=no]
+
+\setupdescriptions [indentnext=no]
+
+%D \section Itemize 
+%D
+%D And these. We typeset itemizations ragged right.
+
+\setupitemgroup
+  [itemize]
+  [indentnext=no,
+   align=right]
+
+%D We align them at the paragraph indentation and
+%D pack them by default.
+
+\setupitemgroup
+  [itemize]
+  [each]
+  [margin=1pc,
+   width=1em,
+   distance=0pt]
+
+\setupitemgroup
+  [itemize]
+  [1]
+  [packed]
+
+%D \section Section Headings %<<<1

+%D We follow the \TUGBOAT\ style for sections. I do not know if
+%D \type{align=right} also disables hyphenation. Lets wait and see on
+%D this. Rest all is straight forward. It took me a while to realize
+%D that in \LATEX\ \type{\@startsection} the absolute value of before
+%D skip (fourth argument) is important and not the sign.

+%D We define a logical skip. This is equal to the \tex{topsep} in latex,
+%D and most environments should have this skip.

+he said
+“those goddamn pakistanis and their goddamn corner shops
+built a shop on every corner, took our british workers jobs”
+he said
+“those goddamn chinese and their goddamn china shops”
+i told him they’re from vietnam, but he didn’t give a toss
+i ask him what was there before that “damn japan man’s shop?”
+he looks at me and dreams a scene of british workers’ jobs
+of full-time, full-employment before the “goddamn boats all came”
+where everybody went to work for full-time full-hours every day
+“a british business stood their first”
+he claims
+“before the irish came
+now british people lost their jobs and bloody turkish they're to blame”
+i ask him how he knows that fact, he says, “because it’s true”
+i ask him how he knows it’s fact, he says, he read it in the news,
+“every time a somali comes here they take a job from us
+the mathematics one for one, from us to them, it just adds up.”
+he bites his cake, he sips his brew, he says again he knows the plot
+“the goddamn caribbean’s came and now good folk here don’t have jobs”
+i ask him what was there before the “goddamn persian curtain shop”
+i show him architectures’ plans
+of empty goddamn plots of land
+I show him the historic maps
+a bit of sand
+a barren land
+there was no goddamn shop before that pakistani came and planned
+man - i am sick of crappy mathematics
+cos i love a bit of sums
+i spent years into economics
+and i geek out over calculus
+and when i meet these paper claims
+that one of every new that came
+takes away ‘our’ daily wage
+i desperately want to scream
+“your math is stuck-in primary”
+cos some who come here also spend
+and some who come here also lend
+and some who come here also tend
+to set up work which employs them
+and all thosebalance sheets and trends
+they work with numbers, not with men
+and all this goddamn heated talk
+ignores the trade the polish brought
+ignores the men they give work to
+not plumbing jobs but further too
+ignores the guys they buy stock from
+accountants, builders, on and on
+and i know it’s nice to have someone
+to blame our lack of jobs upon
+but immigration’s not that plain
+despite the sums inside our brains
+as one for one
+as him for you
+as if he goes ‘home’, they’d employ you
+cos sometimes one that comes makes two
+and sometimes one can add three more
+and sometimes two times two is much, much more than four
+and most times immigrants bring more than minuses.
