+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.

+%D In boring module we define a lot of obscure but useful
+%D system constants. By doing so we save lots of memory while
+%D at the same time we prevent ourself from typing errors.

+%D This file is mostly the same as the \MKII\ variant but we
+%D keep extending \MKIV, so it was bout time to have a dedicated
+%D variant.
+%D
+%D The constants are grouped in such a way that there is a
+%D minimal change of conflicts.

+%D Reference labels can be tagged by users, for instance by
+%D means of \type{tag:}. The reference mechanism itself uses
+%D some tags too. These are definitely not to be used by users.
+%D Here they are:

+\definereferenceconstant {cross} {:c:} % cross reference
+\definereferenceconstant {view} {:v:} % view reference
+\definereferenceconstant {viewa} {:a:} % view reference test a
+\definereferenceconstant {viewb} {:b:} % view reference test b

+%D Variables are composed of a command specific tag and a user
+%D supplied variable (system constant). The first tag \type{ag}
+%D for instance is available as \type{\??ag} and expands to
+%D \type{@@ag} in composed variables.

+%D Special purpose variables:
+
+\def\v!oddeven#1{\ifodd#1\v!odd\else\v!even\fi}
+
+%D The names of files and their extensions are fixed.
+%D \CONTEXT\ uses as less files as possible. Utility files can
+%D be recognized by the first two characters of the extension:
+%D \type{tu}.
+
+\definefileconstant {utilityfilename} {texutil}
+
+\definefileconstant {blockextension} {tub}
+\definefileconstant {figureextension} {tuf}
+\definefileconstant {inputextension} {tui}
+\definefileconstant {outputextension} {tuo} % tup for previous run
+\definefileconstant {optionextension} {top}
+\definefileconstant {temporaryextension} {tmp}
+\definefileconstant {patternsextension} {pat}
+\definefileconstant {hyphensextension} {hyp}
+\definefileconstant {fontmapextension} {map}
+\definefileconstant {bibextension} {bbl}
+
+%D These files are loaded at start||up. They may contain system
+%D specific setups (or calls to other files), old macro's, to
+%D garantee compatibility and new macro's noy yet present in
+%D the format.
+
+\definefileconstant {errfilename} {cont-err}
+\definefileconstant {sysfilename} {cont-sys}
+\definefileconstant {oldfilename} {cont-old}
+\definefileconstant {newfilename} {cont-new}
+\definefileconstant {filfilename} {cont-fil.\mksuffix}
+\definefileconstant {modfilename} {cont-mod}
+
+%D Handy for typescripts (we could use s! instead:
+
+\definetypescriptconstant {name} {name}
+\definetypescriptconstant {default} {default}
+\definetypescriptconstant {map} {map}
+\definetypescriptconstant {special} {special}
+\definetypescriptconstant {size} {size}
+
+%D The next two files specify user settings as well as
+%D \TEXEXEC\ settings when generating a format.
+
+\definefileconstant {usrfilename} {cont-usr} % .tex
+\definefileconstant {fmtfilename} {cont-fmt} % .tex
+
+%D The setup files for the language, font, color and special
+%D subsystems have a common prefix. This means that we have at
+%D most three characters for unique filenames.
+
+\definefileconstant {colorprefix} {colo-}
+\definefileconstant {encodingprefix} {enco-}
+\definefileconstant {filterprefix} {filt-}
+\definefileconstant {fontprefix} {font-}
+\definefileconstant {handlingprefix} {hand-}

+\definefileconstant {privateprefix} {p-}
+\definefileconstant {thirdprefix} {t-}
+
+%definefileconstant {beforeprefix} {b-}
+%definefileconstant {afterprefix} {a-}
+
+%D \CONTEXT\ follows different strategies for finding files.
+%D The macros that are responsible for this 'clever' searching
+%D make use of two (very important) path specifiers.
+
+\definefileconstant {pathseparator} {/}
+\definefileconstant {currentpath} {.}
+\definefileconstant {parentpath} {..}
+
+%D The way fonts are defined and called upon is language
+%D independant. We follow the scheme laid down by Knuth in
+%D Plain \TEX. We'll explain their meaning later.

+%D A careful reader will have noticed that in the module
+%D \type{mult-ini} we defined \type{\selectinterface}. We were
+%D not yet able to actually select an interface, because we
+%D still had to define the constants and variables. Now we've
+%D done so, selection is permitted.
+

+%D title=\CONTEXT\ Support Macros,
+%D subtitle=Boxes,
+%D author=Hans Hagen,

+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
+%C details.
+
+%D This module implements some box manipulation macros. Some
+%D are quite simple, some are more advanced and when understood
+%D well, all can be of use.
+
+%D No longer generic, why bother.
+
+\writestatus{loading}{ConTeXt Support Macros / Boxes}
+
+\unprotect
+
+%D \macros
+%D {strutdp,strutht,strutwd}
+%D
+%D The next shortcuts save memory and keying. The width is
+%D normally zero points (if not, you're in trouble). These
+%D shortcuts can be used like a dimension, opposite to the
+%D core macros \type {\strutdepth} and alike, which are
+%D values.
+
+\def\strutdp{\dp\strutbox}
+\def\strutht{\ht\strutbox}
+\def\strutwd{\wd\strutbox}
+
+%D \macros
+%D {resetbox, emptybox}
+%D
+%D Let's start with an easy one. The next macro hides the
+%D ugly \type {@} in \type {\voidb@x}.
+
+\ifx\voidbox\undefined \newbox\voidbox \fi
+\ifx\voidb@x\undefined \let\voidb@x\voidbox \fi
+
+\def\emptybox {\box \voidbox}
+\def\unvoidbox {\unhbox\voidbox}
+\def\resetbox#1{\setbox#1\box\voidbox}
+
+%D \macros
+%D {nextdepth}
+%D
+%D Let's start with a rather simple declaration. Sometimes we
+%D need to save the \TEX\ \DIMENSION\ \type{\prevdepth} and
+%D append it later on. The name \type{\nextdepth} suits
+%D this purpose well.
+
+\newdimen\nextdepth
+
+%D \macros
+%D {smashbox, smashedbox}
+%D
+%D Smashing is introduced in \PLAIN\ \TEX, and stands for
+%D reducing the dimensions of a box to zero. The most resolute
+%D one is presented first.
+
+\def\smashbox#1%
+ {\wd#1\zeropoint
+ \ht#1\zeropoint
+ \dp#1\zeropoint}
+
+\def\smashboxed#1%
+ {\smashbox{#1}%
+ \box#1\relax}
+
+%D \macros
+%D {hsmashbox,vsmashbox}
+%D
+%D Smashing can be used for overlaying boxes. Depending on
+%D the mode, horizontal or vertical, one can use:
+
+\def\hsmashbox#1%
+ {\wd#1\zeropoint}
+
+\def\vsmashbox#1%
+ {\ht#1\zeropoint
+ \dp#1\zeropoint}
+
+%D The next implementation is less sensitive for spurious
+%D spaces.
+
+\newcount\registercount
+
+\def\smashbox
+ {\afterassignment\dosmashbox\registercount}
+
+\def\dosmashbox
+ {\wd\registercount\zeropoint
+ \ht\registercount\zeropoint
+ \dp\registercount\zeropoint}
+
+\def\smashedbox
+ {\afterassignment\thesmashedbox\registercount}
+
+\def\thesmashedbox
+ {\dosmashbox
+ \box\registercount}
+
+\def\hsmashbox
+ {\afterassignment\dohsmashbox\registercount}
+
+\def\dohsmashbox
+ {\wd\registercount\zeropoint}
+
+\def\vsmashbox
+ {\afterassignment\dovsmashbox\registercount}
+
+\def\dovsmashbox
+ {\ht\registercount\zeropoint
+ \dp\registercount\zeropoint}
+
+%D \macros
+%D {hsmash,vsmash,
+%D hsmashed,vsmashed}
+%D
+%D While the previous macros expected a \BOX, the next act on a
+%D content. They are some subtle differences betreen the smash
+%D and smashed alternatives. The later ones reduce all
+%D dimensions to zero.
+
+% Ok, but inefficient and/or catcode unsafe:
+%
+% \def\hsmash #1{\bgroup\setbox0=\normalhbox{#1}\hsmashbox0\box0\egroup}
+% \def\vsmash #1{\bgroup\setbox0=\normalvbox{#1}\vsmashbox0\box0\egroup}
+% \def\hsmashed#1{\bgroup\setbox0=\normalhbox{#1}\smashbox 0\box0\egroup}
+% \def\vsmashed#1{\bgroup\setbox0=\normalvbox{#1}\smashbox 0\box0\egroup}
+%
+% Better, but a waste of tokens:
+%
+% \def\hsmash {\bgroup\dowithnextbox{\hsmashbox\nextbox\flushnextbox\egroup}\normalhbox}
+% \def\vsmash {\bgroup\dowithnextbox{\vsmashbox\nextbox\flushnextbox\nextbox\egroup}\normalvbox}
+% \def\hsmashed{\bgroup\dowithnextbox{\smashbox \nextbox\flushnextbox\nextbox\egroup}\normalhbox}
+% \def\vsmashed{\bgroup\dowithnextbox{\smashbox \nextbox\flushnextbox\nextbox\egroup}\normalvbox}
+%
+% The best:
+
+\def\dosomesmash#1% (begin|end)group ipv (b|e)group ?
+ {\bgroup\dowithnextbox{#1\nextbox\flushnextbox\egroup}}
+
+\def\hsmash {\dosomesmash\hsmashbox\normalhbox}
+\def\vsmash {\dosomesmash\vsmashbox\normalvbox}
+\def\hsmashed{\dosomesmash\smashbox \normalhbox}
+\def\vsmashed{\dosomesmash\smashbox \normalvbox}
+
+%D \macros
+%D {smashedhbox,smashedvbox}
+%D
+%D Also handy (all dimensions zeroed):
+%D
+%D \starttyping
+%D \smashedhbox to ... {...}
+%D \smashedvbox to ... {...}
+%D \stoptyping
+
+\def\dosmashedbox#1%

+ {#1\bgroup\dowithnextbox{\smashedbox\nextbox\egroup}#1}
+
+\def\smashedhbox{\dosmashedbox\hbox}
+\def\smashedvbox{\dosmashedbox\vbox}
+
+%D \macros
+%D {smash}
+%D
+%D This smash alternative takes an optional arg [whdtb] as
+%D well as is potentially catcode safer. It is needed by the

+%D here).

+%D \macros
+%D {phantom, hphantom, vphantom, mathstrut}
+%D
+%D The next implementation of \type {\phantom} cum suis does
+%D not grab an argument in the non||math case, which is better.
+
+\unexpanded\def\phantom {\ph@nt\nextbox\nextbox\nextbox}
+\unexpanded\def\vphantom{\ph@nt\nextbox\nextbox\voidbox}
+\unexpanded\def\hphantom{\ph@nt\voidbox\voidbox\nextbox}
+
+%D Due to a complicated call to \type {\mathpallete} and
+%D thereby \type {\mathchoice}, the next macro looks ugly.
+%D We also take care of non||braced arguments.
+
+\def\ph@nt#1#2#3%

+%D We also define plain's \type {\mathstrut}.
+
+\unexpanded\def\mathstrut{\vphantom{(}}
+
+%D \macros
+%D {getboxheight}
+%D
+%D Although often needed, \TEX\ does not support arithmics
+%D like:
+%D
+%D \starttyping
+%D \dimen0 = \ht0 + \dp0
+%D \stoptyping
+%D
+%D so we implemented:
+%D
+%D \starttyping
+%D \getboxheight ... \of \box...
+%D \stoptyping
+%D
+%D For instance,
+%D
+%D \starttyping
+%D \getboxheight \dimen0 \of \box0
+%D \getboxheight \someheight \of \box \tempbox
+%D \stoptyping
+%D
+%D The implementation is rather stupid:
+%D
+%D \starttyping
+%D \def\getboxheight#1\of#2\box#3%
+%D {#1\ht#3\advance#1\dp#3\relax}
+%D \stoptyping
+%D
+%D The next alternative is slightly more clever, since
+%D it accepts \type {{12}} as well as \type {12} as box
+%D number.
+
+\def\getboxheight#1\of#2\box#3%
+ {\def\next{#1\dimexpr\ht\registercount+\dp\registercount\relax}%
+ \afterassignment\next\registercount=#3}
+
+%D For a long time the following three macros were part of
+%D the grid snapping core module, but it makes more sense to
+%D have them here so that users can see them.
+%D
+%D \macros
+%D {getnoflines, getroundednoflines, getrawnoflines}
+%D
+%D Het commando \type{\getnoflines} converteert een hoogte
+%D (dimensie) in een aantal regels en kent dit toe aan
+%D \type{\noflines}.
+%D
+%D \starttyping
+%D \getnoflines{dimensie}
+%D \stoptyping
+%D
+%D Er wordt gedeeld door \type{\openlineheight} en een hoogte
+%D van~0pt komt overeen met 0~regels. The raw alternative
+%D does not round.
+
+%D For a long time we had:
+%D
+%D \starttyping
+%D \newcount\noflines
+%D \newdimen\noflinesheight
+%D
+%D \def\dogetnoflines#1#2%

+%D
+%D \def\getnoflines {\dogetnoflines\iftrue } % compensated
+%D \def\getrawnoflines{\dogetnoflines\iffalse} % no compensation

+%D \macros
+%D {dowithnextbox,nextbox}
+%D
+%D Sometimes we want a macro to grab a box and do something
+%D on the content. One could pass an argument to a box, but
+%D this can violate the specific \CATCODES\ of its content and
+%D leads to unexpected results. The next macro treats the
+%D following braced text as the content of a box and
+%D manipulates it afterwards in a predefined way.
+%D
+%D The first argument specifies what to do with the content.
+%D This content is available in \type{\nextbox}. The second
+%D argument is one of \type{\hbox}, \type{\vbox} or
+%D \type{\vtop}. The third argument must be grouped with
+%D \type{\bgroup} and \type{\egroup}, \type{{...}} or can be
+%D a \type{\box} specification.
+%D
+%D In \CONTEXT\ this macro is used for picking up a box and
+%D treating it according to earlier specifications. We use for
+%D instance something like:
+%D
+%D \starttyping
+%D \def\getfloat%
+%D {\def\handlefloat{...\flushnextbox...}
+%D \dowithnextbox\handlefloat\normalvbox}
+%D \stoptyping
+%D
+%D instead of:
+%D
+%D \starttyping
+%D \def\getfloat#1%
+%D {...#1...}
+%D \stoptyping
+%D
+%D In this implementation the \type{\aftergroup} construction
+%D is needed because \type{\afterassignment} is executed inside
+%D the box.
+
+\ifx\nextbox\undefined \newbox\nextbox \fi
+
+\long\def\dowithnextbox#1%
+ {\long\def\dodowithnextbox{#1}%
+ \afterassignment\dododowithnextbox

+ {\let\dodowithnextbox#1%
+ \afterassignment\dododowithnextbox
+ \setbox\nextbox}
+
+\def\dododowithnextbox
+ {\aftergroup\dodowithnextbox}
+
+%D So in fact we get:
+%D
+%D \starttyping
+%D \setbox\nextbox { \aftergroup\dodowithnextbox ... }
+%D \stoptyping
+%D
+%D or
+%D
+%D \starttyping
+%D \setbox\nextbox { ... } \dodowithnextbox
+%D \stoptyping
+%D
+%D A slower but more versatile implementation is:
+%D
+%D \starttyping
+%D \long\def\dowithnextbox#1#2%
+%D {\long\def\dodowithnextbox{#1}%
+%D \ifx#2\normalhbox
+%D \afterassignment\dododowithnextbox
+%D \else\ifx#2\normalvbox
+%D \afterassignment\dododowithnextbox
+%D \else\ifx#2\normalvtop
+%D \afterassignment\dododowithnextbox
+%D \else\ifx#2\normalvcenter
+%D \afterassignment\dododowithnextbox
+%D \else
+%D \afterassignment\dodowithnextbox
+%D \fi\fi\fi\fi
+%D \setbox\nextbox#2}
+%D \stoptyping
+%D
+%D This alternative also accepts \type{\box0} and alike, but
+%D we don't really need this functionality now.
+
+%D \macros
+%D {nextboxht,nextboxwd,nextboxdp,flushnextbox}
+%D
+%D The next couple of shortcuts saves us memory as well as
+%D \type {{}}'s in passing parameters.
+
+\def\nextboxht{\ht\nextbox}
+\def\nextboxwd{\wd\nextbox}
+\def\nextboxdp{\dp\nextbox}
+
+\def\flushnextbox{\box\nextbox}
+
+%D \macros
+%D {dowithnextboxcontent}
+%D
+%D But, occasionally we do need to pass some local settings
+%D without wanting to use additional grouping. Therefore we
+%D provide:
+%D
+%D \starttyping
+%D \dowithnextboxcontent{inside}{after}{box content}
+%D \stoptyping
+%D
+%D {\em todo: Search source for potential usage!}
+
+\long\def\dowithnextboxcontent#1#2% inside, after
+ {\long\def\dodowithnextbox{#2}%
+ \def\dododowithnextbox{#1\aftergroup\dodowithnextbox}%
+ \afterassignment\dododowithnextbox
+ \setbox\nextbox}
+
+%D Now we can redefine \type {\dowithnextbox} as follows:
+%D
+%D \starttyping
+%D \def\dowithnextbox{\dowithnextboxcontent\empty}
+%D \stoptyping
+%D
+%D But since this macro is used often and since this implementation
+%D is slower, we will not use that definition.
+
+% maybe:
+%
+% depending on the size of the action, about 10% faster

+%D \macros
+%D {beginofshapebox,
+%D reshapebox, doreshapebox,
+%D flushshapebox,
+%D innerflushshapebox,
+%D shapebox,
+%D ifreshapingbox}
+%D
+%D The next utility macro originates from some linenumbering
+%D mechanism. Due to \TEX's advanced way of typesetting
+%D paragraphs, it's not easy to do things on a line||by||line
+%D basis. This macro is able to reprocess a given box and can
+%D act upon its vertical boxed components, such as lines. The
+%D unwinding sequence in this macro is inspired by a \NTG\
+%D workshop of David Salomon in June 1992.
+%D
+%D First we have to grab the piece of text we want to act
+%D upon. This is done by means of the duo macros:
+%D
+%D \starttyping
+%D \beginofshapebox
+%D a piece of text
+%D \endofshapebox
+%D \stoptyping
+%D
+%D When all texts is collected, we can call \type{\reshapebox}
+%D and do something with it's vertical components. We can make
+%D as much passes as needed. When we're done, the box can be
+%D unloaded with \type{\flushshapebox}. The only condition in
+%D this scheme is that \type{\reshapebox} must somehow unload
+%D the \BOX\ \type{\shapebox}.
+%D
+%D An important aspect is that the content is unrolled
+%D bottom||up. The next example illustrates this maybe
+%D unexpected characteristic.
+%D
+%D \startbuffer
+%D \beginofshapebox
+%D \em \input tufte
+%D \endofshapebox
+%D
+%D \newcounter\LineNumber
+%D
+%D \reshapebox
+%D {\doglobal\increment\LineNumber
+%D \normalhbox{\llap{\LineNumber\hskip2em}\box\shapebox}}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \getbuffer
+%D
+%D As we can see, when some kind of numbering is done, we have
+%D to add a second pass.
+%D
+%D \startbuffer
+%D \newcounter\LineNumber
+%D \newcounter\NumberOfLines
+%D
+%D \reshapebox
+%D {\doglobal\increment\NumberOfLines
+%D \box\shapebox}
+%D
+%D \reshapebox
+%D {\doglobal\increment\LineNumber
+%D \normalhbox
+%D {\llap{\LineNumber\ (\NumberOfLines)\hskip2em}%
+%D \box\shapebox}%
+%D \doglobal\decrement\NumberOfLines}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \getbuffer
+%D
+%D This example shows that the content of the box is still
+%D available after flushing. Another feature is that only the
+%D last reshaping counts. Multiple reshaping can be done by:
+%D
+%D \startbuffer
+%D \beginofshapebox
+%D \flushshapebox
+%D \endofshapebox
+%D
+%D \reshapebox
+%D {\doglobal\increment\LineNumber
+%D \normalhbox{\llap{$\star$\hskip1em}\box\shapebox}%
+%D \doglobal\decrement\NumberOfLines}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \getbuffer
+%D
+%D The macros are surprisingly easy to follow and in fact
+%D introduce no new concepts. Nearly all books on \TEX\ show
+%D similar solutions for unwinding \BOXES.
+%D
+%D Some macros, like footnote ones, can be sensitive for
+%D reshaping, which can result in an endless loop. We
+%D therefore offer:
+%D
+%D \starttyping
+%D \ifreshapingbox
+%D \stoptyping
+%D
+%D Some \CONTEXT\ commands are protected this way. Anyhow,
+%D reshaping is aborted after 100 dead cycles.
+%D
+%D By the way, changing the height and depth of \BOX\
+%D \type{\shapebox} results in bad spacing. This means that
+%D for instance linenumbers etc. should be given zero height
+%D and depth before being lapped into the margin. The
+%D previous examples ignore this side effect, but beware!

+%D \macros
+%D {hyphenatedword,
+%D hyphenatedpar,
+%D hyphenatedfile,
+%D dohyphenateword}
+%D
+%D The next one is a tricky one. \PLAIN\ \TEX\ provides
+%D \type{\showhyphens} for showing macros on the terminal. When
+%D preparing a long list of words we decided to show the
+%D hyphens, but had to find out that the \PLAIN\ alternative
+%D can hardly be used and|/|or adapted to typesetting. The next
+%D two macros do the job and a little more. First we define the
+%D (slightly adapted) plain variant:
+
+\def\showhyphens#1%
+ {\begingroup
+ \setbox\scratchbox\vbox
+ {\parfillskip\zerocount
+ \hsize\maxdimen
+ %\tenrm
+ \pretolerance\minusone
+ \tolerance\minusone
+ \hbadness\zerocount
+ \showboxdepth\zerocount
+ \ #1}%
+ \endgroup}
+
+%D The simple command \type{\hyphenatedword} accepts one
+%D argument and gives the hyphenated word. This macro calls for
+%D
+%D \starttyping
+%D \dohyphenateword {n} {pre} {word}
+%D \stoptyping
+%D
+%D The next examples tell more than lots of words:
+%D
+%D \startbuffer
+%D \dohyphenateword{0} {} {dohyphenatedword}
+%D \dohyphenateword{1} {...} {dohyphenatedword}
+%D \dohyphenateword{2} {...} {dohyphenatedword}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Here, \type{\hyphenatedword{dohyphenatedword}} is the
+%D shorter alternative for the first line.
+%D
+%D \startvoorbeeld

+%D We fully agree with (most) typographers that inter||letter

+%D
+%D This results in:
+%D

+%D The list of tokens may contain spaces, while \type{\\},
+%D \type{{}} and \type{\ } are handled as space too.

+%D {doboundtext}
+%D
+%D Sometimes there is not enough room to show the complete
+%D (line of) text. In such a situation we can strip of some
+%D characters by using \type{\doboundtext}. When the text is
+%D wider than the given width, it's split and the third
+%D argument is appended. When the text to be checked is packed
+%D in a command, we'll have to use \type{\expandafter}.
+%D
+%D \starttyping
+%D \doboundtext{a very, probably to long, text}{3cm}{...}
+%D \stoptyping
+%D
+%D When calculating the room needed, we take the width of the
+%D third argument into account, which leads to a bit more
+%D complex macro than needed at first sight.

+%D A bit more beautiful alternative for the previous command is

+%D \macros
+%D {processisolatedwords,
+%D betweenisolatedwords,nothingbetweenisolatedwords}
+%D
+%D References are often made up of one word or a combination
+%D of tightly connected words. The typeset text {\bf
+%D chapter~5} is for instance the results of the character
+%D sequence:
+%D
+%D \starttyping
+%D The typeset text \in{chapter}[texniques] is for instance
+%D \stoptyping
+%D
+%D When such words are made active in interactive texts, the
+%D combination cannot longer be hyphenated. Normally this is no
+%D problem, because \TEX\ tries to prevent hyphenation as best
+%D as can.
+%D
+%D Sometimes however we need a few more words to make things
+%D clear, like when we want to refer to {\bf \TEX\ by Topic}.
+%D The macros that are responsible for typesetting hyperlinks,
+%D take care of such sub||sentences by breaking them up in
+%D words. Long ago we processed words using the space as a
+%D separator, but the more advanced our interactive text became,
+%D the more we needed a robust solution. Well, here it is and
+%D it called as:
+%D
+%D \starttyping
+%D \processisolatedwords{some words}\someaction
+%D \stoptyping
+%D
+%D The second argument \type{someactions} handles the
+%D individual words, like in:
+%D
+%D \startbuffer
+%D \processisolatedwords{some more words} \ruledhbox \par
+%D \processisolatedwords{and some $x + y = z$ math} \ruledhbox \par
+%D \processisolatedwords{and a \normalhbox{$x + y = z$}} \ruledhbox \par
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D which let the words turn up as:
+%D
+%D \startvoorbeeld
+%D \getbuffer
+%D \stopvoorbeeld
+%D
+%D The macro has been made a bit more clever than needed at
+%D first sight. This is due to the fact that we don't want to
+%D generate more overhead in terms of interactive commands than
+%D needed.
+%D
+%D \startbuffer
+%D \processisolatedwords{see this \ruledhskip1em} \ruledhbox
+%D \processisolatedwords{and \ruledhskip1em this one} \ruledhbox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D becomes:
+%D
+%D \startvoorbeeld
+%D \startlines
+%D \getbuffer
+%D \stoplines
+%D \stopvoorbeeld
+%D
+%D Single word arguments are treated without further
+%D processing. This was needed because this command is used in
+%D the \type{\goto} command, to which we sometimes pass very
+%D strange and|/|or complicated arguments or simply boxes
+%D whose dimensions are to be left intact.
+%D
+%D First we build a \type{\normalhbox}. This enables us to save the
+%D last skip. Next we fill a \type{\normalvbox} without hyphenating
+%D words. After we've tested if there is more than one word, we
+%D start processing the individual lines (words). We need some
+%D splitting, packing and unpacking to get the spacing and
+%D dimensions right.
+%D
+%D Normally the isolated words are separated by space, but
+%D one can overrule this separator by changing the next macros.
+%D
+%D When needed, spacing can be suppressed by \type
+%D {\nothingbetweenisolatedwords}.

+%D One can use the next macro to change the intersplit

+%D at all. So, the innermost settings are used, while the
+%D outermost split takes place.

+%D \macros
+%D {centeredbox, centerednextbox}
+%D
+%D Here is another strange one. This one offers a sort of overlay
+%D with positive or negative offsets. This command can be used
+%D in well defined areas where no offset options are available.
+%D We first used it when building a button inside the margin
+%D footer, where the button should have a horizontal offset and
+%D should be centered with respect to the surrounding box. The
+%D last of the three examples we show below says:
+%D
+%D \starttyping
+%D \vsize=3cm
+%D \hsize=3cm
+%D \ruledvbox to \vsize
+%D {\centeredbox height .5cm width -1cm
+%D {\vrule width \hsize height \vsize}}}
+%D \stoptyping
+%D
+%D Here the \type{\ruledvbox} just shows the surrounding box
+%D and \type{\vrule} is used to show the centered box.
+%D
+%D \def\AnExample#1#2%
+%D {\vsize=3cm

+%D
+%D This command takes two optional arguments: \type{width} and
+%D \type{height}. Observing readers can see that we use \TEX's
+%D own scanner for grabbing these arguments: \type{#1#} reads
+%D everyting till the next brace and passes it to both rules.
+%D The setting of the box dimensions at the end is needed for
+%D special cases. The dimensions of the surrounding box are kept
+%D intact. This commands handles positive and negative
+%D dimensions (which is why we need two boxes with rules).

+%D Here is another of Knuth's dirty tricks, as presented on
+%D pages 398 and 399 of the \TEX book. These macros can be used
+%D like:
+%D
+%D \starttyping
+%D \normalvbox

+%D
+%D \normalvbox
+%D \bgroup
+%D \convertvboxtohbox
+%D \egroup

+%D These macros are used in reformatting footnotes, so they do
+%D what they're meant for.

+%D This macro can be used to break a paragraph apart and treat
+%D each line seperately, for instance, making it clickable. The
+%D main complication is that we want to be able to continue the
+%D paragraph, something that's needed in the in line section
+%D headers.
+%D
+%D \startbuffer
+%D \setbox0=\normalhbox{\input tufte \relax}
+%D \setbox2=\normalhbox{\input knuth \relax}
+%D \unhhbox0\with{\ruledhbox{\box\hhbox}}
+%D \hskip1em plus 1em minus 1em
+%D \hhboxindent=\lasthhboxwidth
+%D \advance\hhboxindent by \lastskip
+%D \unhhbox2\with{\ruledhbox{\box\hhbox}}
+%D \stopbuffer
+%D
+%D \getbuffer
+%D
+%D This piece of text was typeset by saying:
+%D
+%D \typebuffer
+%D
+%D Not that nice a definition, but effective. Note the stretch
+%D we've build in the line that connects the two paragraphs.
+
+%D \macros
+%D {doifcontent}
+%D
+%D When processing depends on the availability of content, one
+%D can give the next macro a try.
+%D
+%D \starttyping
+%D \doifcontent{pre content}{post content}{no content}\somebox
+%D \stoptyping
+%D
+%D Where \type{\somebox} is either a \type{\normalhbox} or
+%D \type{\normalvbox}. If the dimension of this box suggest some
+%D content, the resulting box is unboxed and surrounded by the
+%D first two arguments, else the third arguments is executed.
+
+\unexpanded\def\doifcontent#1#2#3%
+ {\dowithnextbox
+ {\ifhbox\nextbox
+ \ifdim\nextboxwd>\zeropoint
+ #1\unhbox\nextbox#2\relax
+ \else
+ #3\relax
+ \fi
+ \else
+ \ifdim\nextboxht>\zeropoint
+ #1\unvbox\nextbox#2\relax
+ \else
+ #3\relax
+ \fi
+ \fi}}
+
+%D So when we say:
+%D
+%D \startbuffer
+%D \doifcontent{[}{]}{}\normalhbox{content sensitive typesetting}
+%D
+%D \doifcontent{}{\page}{}\normalvbox{content sensitive typesetting}
+%D
+%D \doifcontent{}{}{\message{Didn't you forget something?}}\normalhbox{}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D We get:
+%D
+%D \getbuffer
+%D
+%D Where the last call of course does not show up in this
+%D document, but definitely generates a confusing message.

+%D \rbox{text ...}
+%D \stoptyping
+%D
+%D Are similar to \type {\normalvbox}, which means that they also

+%D middle and right. These box types can be used to typeset
+%D paragraphs.

+%D
+%D \startbuffer
+%D \DroppedCaps
+%D {\color[green]} {cmbx12}
+%D {2.2\baselineskip} {2pt} {\baselineskip} {2}
+%D Let's start
+%D \stopbuffer
+%D
+%D \getbuffer with dropped caps, those blown up first
+%D characters of a paragraph. It's hard to implement a general
+%D mechanism that suits all situations, but dropped caps are so
+%D seldomly used that we can permit ourselves a rather user
+%D unfriendly implementation.
+%D
+%D \typebuffer
+%D
+%D As we will see, there are 7 different settings involved. The
+%D first argument takes a command that is used to do whatever
+%D fancy things we want to do, but normally this one will be
+%D empty. The second argument takes the font. Because we're
+%D dealing with something very typographic, there is no real
+%D reason to adopt complicated font switching schemes, a mere
+%D name will do. Font encodings can bring no harm, because the
+%D alphanumeric characters are nearly always located at their
+%D natural position in the encoding vector.
+%D
+%D \startbuffer
+%D \DroppedCaps
+%D {\color[red]} {cmbx12}
+%D {\baselineskip} {0pt} {0pt} {1}
+%D This simple
+%D \stopbuffer
+%D
+%D \getbuffer case shows us what happens when we apply minimal
+%D values. Here we used:
+%D
+%D \typebuffer
+%D
+%D \startbuffer
+%D \DroppedCaps
+%D {\color[red]} {cmbx12}
+%D {2\baselineskip} {0pt} {\baselineskip} {2}
+%D Is this ugly
+%D \stopbuffer
+%D
+%D \getbuffer example the third argument tells
+%D this macro that we want a dropped capital scaled to the
+%D baseline distance. The two zero point arguments are the
+%D horizontal and vertical offsets and the last arguments
+%D determines the hanging indentation. In this paragraph we
+%D set the height to two times the baselinedistance and use
+%D two hanging lines:
+%D
+%D \typebuffer
+%D
+%D Here, the first character is moved down one baseline. Here
+%D we also see why the horizontal offset is important. The
+%D first example (showing the~L) sets this to a few points and
+%D also used a slightly larger height.
+%D
+%D Of course common users (typist) are not supposed to see this
+%D kind of fuzzy definitions, but fortunately \TEX\ permits us
+%D to hide them in macros. Using a macro also enables us to
+%D garantee consistency throughout the document:
+%D
+%D \startbuffer
+%D \def\MyDroppedCaps%
+%D {\DroppedCaps
+%D {\color[green]} {cmbx12}
+%D {5\baselineskip} {3pt} {3\baselineskip} {4}}
+%D
+%D \MyDroppedCaps The implementation
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \getbuffer of the general macro is rather simple and only
+%D depends on the arguments given and the dimensions of the
+%D strut box. We explicitly load the font, which is no problem
+%D because \TEX\ does not load a font twice. We could have
+%D combined some arguments, like the height, vertical offset
+%D and the number of lines, but the current implementation
+%D proved to be the most flexible. One should be aware of the
+%D fact that the offsets depend on the design of the glyphs
+%D used.

+%D \typebuffer
+%D
+%D \startbuffer
+%D \TreatFirstLine {\startcolor[red]\bf} {\stopcolor} {} {}
+%D The combined color and font effect is also possible,
+%D although one must be careful in using macros that accumulate
+%D grouping, but the commands used here are pretty save in that
+%D respect.

+%D Before we explain the third and fourth argument, we show the
+%D implementation. Those who know a bit about the way \TEX\
+%D treats tokens, will probably see in one glance that this
+%D alternative works all right for most text||only situations
+%D in which there is enough text available for the first line,
+%D but that more complicated things will blow. One has to live
+%D with that. A workaround is rather trivial but obscures the
+%D principles used.

+%D The third and fourth argument can be used to gain special
+%D effects on the individual words. Of course one needs ...
+%D \stopbuffer
+%D
+%D \getbuffer
+%D to know a bit more about the macro package used to get real
+%D nice effects, but this example probably demonstrates the
+%D principles well.
+%D
+%D \typebuffer
+%D
+%D Like in dropped caps case, one can hide such treatments in a
+%D macro, like:
+%D
+%D \starttyping
+%D \def\MyTreatFirstLine%
+%D {\TreatFirstLine{\bf}{}{\FunnyCommand}{\FunnyCommand}}
+%D \stoptyping
+
+%D \macros
+%D {reshapebox}
+%D
+%D \startbuffer
+%D \beginofshapebox
+%D When using \CONTEXT, one can also apply this funny command
+%D to whole lines by using the reshape mechanism. Describing
+%D this interesting mechanism falls outside the scope of this
+%D module, so we only show the trick. This is an example of
+%D low level \CONTEXT\ functionality: it's all there, and it's
+%D stable, but not entirely meant for novice users.
+%D \endofshapebox
+%D
+%D \reshapebox{\FunnyCommand{\box\shapebox}} \flushshapebox
+%D \stopbuffer
+%D
+%D \getbuffer
+%D
+%D \typebuffer
+%D
+%D This mechanism permits hyphenation and therefore gives
+%D better results than the previously discussed macro
+%D \type{\TreatFirstLine}.
+
+%D \macros
+%D {TreatFirstCharacter}
+%D
+%D \startbuffer
+%D \TreatFirstCharacter{\bf\color[green]} Just to be
+%D \stopbuffer
+%D
+%D \getbuffer complete we also offer a very simple one
+%D character alternative, that is not that hard to understand:
+
+\def\TreatFirstCharacter#1#2% command, character
+ {{#1{#2}}}
+
+%D A previous paragraph started with:
+%D
+%D \typebuffer
+
+%D \macros
+%D {StackCharacters}
+%D
+%D The next hack deals with vertical stacking.
+
+\def\StackCharacters#1#2#3#4% sequence vsize vskip command
+ {\vbox #2
+ {\forgetall
+ \baselineskip\zeropoint
+ \def\StackCharacter##1{#4{##1}\cr\noalign{#3}}%
+ \halign

+ \handletokens#1\with\StackCharacter\cr}}}
+
+%D \startbuffer
+%D \StackCharacters{CONTEXT}{}{\vskip.2ex}{\FunnyCommand}
+%D \stopbuffer
+%D
+%D Such a stack looks like:
+%D
+%D \startlinecorrection
+%D \hbox to \hsize
+%D {$\hss\bfd
+%D \vcenter{\StackCharacters{TEX} {}{\vskip.2ex}{\FunnyCommand}}%
+%D \hss
+%D \vcenter{\StackCharacters{CON} {}{\vskip.2ex}{\FunnyCommand}}
+%D \hss
+%D \vcenter{\StackCharacters{TEXT} {}{\vskip.2ex}{\FunnyCommand}}
+%D \hss
+%D \vcenter{\StackCharacters{CONTEXT}{}{\vskip.2ex}{\FunnyCommand}}
+%D \hss$}
+%D \stoplinecorrection
+%D
+%D and is typeset by saying:
+%D
+%D \typebuffer
+%D
+%D An alternative would have been
+%D
+%D \starttyping
+%D \StackCharacters {CONTEXT} {to 5cm} {\vfill} {\FunnyCommand}
+%D \stoptyping
+
+%D \macros
+%D {processtokens}
+%D
+%D At a lower level horizontal and vertical manipulations are
+%D already supported by:
+%D
+%D \starttyping
+%D \processtokens {begin} {between} {end} {space} {text}
+%D \stoptyping
+%D
+%D \startbuffer[a]
+%D \processtokens
+%D {\hbox to .5\hsize\bgroup} {\hfill}
+%D {\egroup} {\space} {LET'S HAVE}
+%D \stopbuffer
+%D
+%D \startbuffer[b]
+%D \processtokens
+%D {\vbox\bgroup\raggedcenter\hsize1em}
+%D {\vskip.25ex} {\egroup} {\strut} {FUN}
+%D \stopbuffer
+%D
+%D This macro is able to typeset:
+%D
+%D \leavevmode\hbox to \hsize
+%D {$\hfil\hfil
+%D \vcenter{\bf\getbuffer[a]}%
+%D \hfil
+%D \vcenter{\bfd\getbuffer[b]}%
+%D \hfil\hfil$}
+%D
+%D which was specified as:
+%D
+%D \typebuffer[a]
+%D \typebuffer[b]
+
+%D \macros
+%D {NormalizeFontHeight, NormalizeFontWidth,
+%D TheNormalizedFontSize}
+%D
+%D Next we introduce some font manipulation macros. When we
+%D want to typeset some text spread in a well defined area, it
+%D can be considered bad practice to manipulate character and
+%D word spacing. In such situations the next few macros can be
+%D of help:
+%D
+%D \starttyping
+%D \NormalizeFontHeight \name {sample text} {height} {font}
+%D \NormalizeFontWidth \name {sample text} {width} {font}
+%D \stoptyping
+%D
+%D These are implemented using an auxilliary macro:
+
+\def\NormalizeFontHeight{\NormalizeFontSize\ht}
+\def\NormalizeFontWidth {\NormalizeFontSize\wd}
+
+% \def\NormalizeFontSize#1#2#3#4#5%
+% {\bgroup
+% \dimen0=#4% #4 can be \ht0 or so
+% \setbox0\hbox{\definedfont[#5 at 10pt]#3}%
+% \ifdim\wd0>\zeropoint
+% \dimen2=#10 % #1 is \wd or \ht
+% \dimen4=10000pt
+% \divide\dimen4 \dimen2
+% \divide\dimen0 \plusthousand
+% \dimen0=\number\dimen4\dimen0
+% \xdef\TheNormalizedFontSize{\the\dimen0}%
+% \else
+% \dimen0\bodyfontsize
+% \fi
+% \definedfont[#5 at \the\dimen0]%
+% \expandafter
+% \egroup
+% \expandafter\font\expandafter#2\fontname\font\relax}
+%
+% the familiar struggle with accuracy forces us to use:
+
+\def\NormalizeFontSize#1#2#3#4#5%
+ {\bgroup
+ \dimen0=#4% #4 can be \ht0 or so
+ \setbox0\hbox{\definedfont[#5 at 5pt]#3}% 10pt
+ \ifdim\wd0>\zeropoint
+ \dimen2=#10 % #1 is \wd or \ht
+ \dimen4=\maxdimen % 10000pt
+ \divide\dimen4 \dimen2
+ \divide\dimen0 1638 % 1000
+ \dimen0=\number\dimen4\dimen0
+ \divide \dimen0 \plustwo % ...
+ \xdef\TheNormalizedFontSize{\the\dimen0}%
+ \else
+ \dimen0\bodyfontsize
+ \fi
+ % mkii
+ % \definedfont[#5 at \the\dimen0]%
+ % \expandafter
+ % \egroup
+ % \expandafter\font\expandafter#2\fontname\font\relax}
+ % mkiv safe (file: prefix etc)
+ \expanded{\egroup\def\noexpand#2{\definedfont[#5 at \the\dimen0]}}}
+
+%D Afterwards, we have access to the calculated size by:
+
+\let\TheNormalizedFontSize\!!zeropoint
+
+%D Extra:
+
+\def\WidthSpanningText#1#2#3% text width font
+ {\hbox{\NormalizeFontWidth\temp{#1}{#2}{#3}\temp\the\everydefinedfont#1}}
+
+%D Consider for instance:
+%D
+%D \startbuffer
+%D \NormalizeFontHeight \tmp {X} {2\baselineskip} {cmr10}
+%D
+%D {\tmp To Be Or Not To Be}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D This shows up as (we also show the baselines):
+%D
+%D {\showbaselines\getbuffer}
+%D
+%D The horizontal counterpart is:
+%D
+%D \startbuffer
+%D \NormalizeFontWidth \tmp {This Line Fits} {\hsize} {cmr10}
+%D
+%D \hbox{\tmp This Line Fits}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D The calculated font scale is avaliable in the macro
+%D \type{\NormalizedFontSize}.
+%D
+%D \startlinecorrection
+%D \ruledhbox{\getbuffer}
+%D \stoplinecorrection
+%D
+%D One can of course combine these macros with the ones
+%D described earlier, like in:
+%D
+%D \starttyping
+%D \NormalizeFontHeight {text} \DroppedFont {2\baselineskip} {cmbx12}
+%D
+%D \def\NicelyDroppedCaps
+%D {\DroppedCaps
+%D {\color[green]}
+%D {\DroppedFont}
+%D {2pt}
+%D {\baselineskip}
+%D {2}}
+%D \stoptyping
+%D
+%D It's up to the reader to test this one.

+%D
+%D We also permit:

+%D These macros are complicated by the fact that we also
+%D have to support cases like:
+%D
+%D \starttyping
+%D {\digits1234}
+%D \digits{1234}
+%D \digits 1234\whatever
+%D $\digits 123.222,00$
+%D \digits 123.222,00.
+%D \stoptyping
+%D
+%D The latter case shows us that trailing non digits are to
+%D be passed untreated.
+%D
+%D Another interesting case is:
+%D
+%D \starttyping
+%D \digits 123.222,00^10
+%D \stoptyping
+%D
+%D The separator is defined as:

+%D \macros

+%D Although an integral part of \CONTEXT, this module is one
+%D of the support modules. Its stand alone character permits
+%D use in \PLAIN\ \TEX\ or \TEX\ based macropackages.
+%D \ifCONTEXT \else If in some examples the verbatim listings
+%D don't show up nice, this is due to processing by a system
+%D that does not support buffering. In \CONTEXT\ we show the
+%D commands in the margin, use bit more advanced way of
+%D numbering, and typeset the source in \TEX nicolored
+%D verbatim. Sorry for this inconvenience.\fi
+%D
+%D Depending on my personal needs and those of whoever uses it,
+%D the macros will be improved in terms of visualization,
+%D efficiency and compatibility. These rather low level
+%D visualization macros are supplemented by ones that can
+%D visualize baselines, the page layout and whatever deserves
+%D attention. Most of those macros can be found in \type
+%D {core-vis} and other core modules. Their integration in
+%D \CONTEXT\ prohibits generic applications.
+
+\ifx \undefined \writestatus \input supp-mis.tex \fi
+
+%D One of the strong points of \TEX\ is abstraction of textual
+%D input. When macros are defined well and do what we
+%D want them to do, we will seldom need the tools present in
+%D What You See Is What You Get systems. For instance, when
+%D entering text we don't need rulers, because no manual
+%D shifting and/or alignment of text is needed. On the other
+%D hand, when we are designing macros or specifying layout
+%D elements, some insight in \TEX's advanced spacing, kerning,
+%D filling, boxing and punishment abilities will be handy.
+%D That's why we've implemented a mechanism that shows some of
+%D the inner secrets of \TEX.
+
+\writestatus{loading}{ConTeXt Support Macros / Visualization}
+
+%D In this module we are going to redefine some \TEX\
+%D primitives and \PLAIN\ macro's. Their original meaning is
+%D saved in macros with corresponding names, preceded by
+%D \type{normal}. These original macros are (1)~used to
+%D temporary restore the old values when needed and
+%D (2)~used to prevent recursive calls in the macros that
+%D replace them.

+%D \macros
+%D {dontinterfere}
+%D
+%D Indentation, left and/or right skips, redefinition of
+%D \type{\par} and assignments to \type{\everypar} can lead to
+%D unwanted results. We can therefore turn all those things
+%D off with \type{\dontinterfere}.

+%D {dontcomplain}
+%D
+%D In this module we do a lot of box manipulations. Because we
+%D don't want to be confronted with to many over- and underfull
+%D messages we introduce \type{\dontcomplain}.

+%D \macros
+%D {normalhbox,
+%D normalvbox,normalvtop}
+%D
+%D There are three types of boxes, one horizontal and two
+%D vertical in nature. As we will see later on, all three types
+%D are to be handled according to their orientation and
+%D baseline behavior. Especially \type{\vtop}'s need our
+%D special attention.
+
+% already saved

+%D \macros

+%D
+%D Next come the flexible skips, which come in two flavors
+%D too. Like boxes these are handled with \TEX\ primitives.
+
+% already saved
+
+%D \macros
+%D {normalpenalty,
+%D normalkern}
+%D
+%D Both penalties and kerns are taken care of by mode sensitive
+%D primitives. This means that when making them visible, we
+%D have to take the current mode into account.
+
+% already saved
+
+%D \macros
+%D {normalhglue,
+%D normalvglue}
+%D
+%D Glues on the other hand are macro's defined in \PLAIN\ \TEX.
+%D As we will see, their definitions make the implementation of
+%D their visible counterparts a bit more \TeX{}nical.
+
+\let\normalhglue = \hglue
+\let\normalvglue = \vglue
+
+%D \macros
+%D {normalmkern,
+%D normalmskip}
+%D
+%D Math mode has its own spacing primitives, preceded by
+%D \type{m}. Due to the relation with the current font and the
+%D way math is typeset, their unit \type{mu} is not compatible
+%D with other dimensions. As a result, the visual appearance
+%D of these primitives is kept primitive too.
+
+% already saved
+
+%D \macros
+%D {hfilneg,
+%D vfilneg}
+%D
+%D Fills can be made visible quite easy. We only need some
+%D additional negation macros. Because \PLAIN\ \TEX\ only
+%D offers \type{\hfilneg} and \type{\vfilneg}, we define our
+%D own alternative double \type{ll}'ed ones.
+
+\def\hfilneg {\normalhskip\zeropoint \!!plus-1fil\relax}
+\def\vfilneg {\normalvskip\zeropoint \!!plus-1fil\relax}
+\def\hfillneg {\normalhskip\zeropoint \!!plus-1fill\relax}

+\def\hfilllneg{\normalhskip\zeropoint \!!plus-1filll\relax}
+\def\vfilllneg{\normalvskip\zeropoint \!!plus-1filll\relax}
+
+%D \macros
+%D {normalhss,normalhfil,normalhfill,
+%D normalvss,normalvfil,normalvfill}
+%D
+%D The positive stretch primitives are used independant and in
+%D combination with \type{\leaders}.
+
+% already saved
+
+%D \macros
+%D {normalhfilneg,normalhfillneg,
+%D normalvfilneg,normalvfillneg}
+%D
+%D Keep in mind that both \type{\hfillneg} and \type{\vfillneg}
+%D are not part of \PLAIN\ \TEX\ and therefore not documented
+%D in standard \TEX\ documentation. They can nevertheless be
+%D used at will.
+
+\let\normalhfillneg = \hfillneg
+\let\normalvfillneg = \vfillneg
+
+%D Visualization is not always wanted. Instead of turning this
+%D option off in those (unpredictable) situations, we just
+%D redefine a few \PLAIN\ macros.

+%D \macros
+%D {makeruledbox}
+%D
+%D Ruled boxes can be typeset is many ways. Here we present
+%D just one alternative. This implementation may be a little
+%D complicated, but it supports all three kind of boxes. The
+%D next command expects a \BOX\ specification, like:
+%D
+%D \starttyping
+%D \makeruledbox0
+%D \stoptyping
+
+%D \macros
+%D {baselinerule,baselinefill}
+%D
+%D We can make the baseline of a box visible, both dashed and
+%D as a rule. The line is drawn on top of the baseline. All
+%D we have to say is:
+%D
+%D \starttyping
+%D \baselineruletrue
+%D \baselinefilltrue
+%D \stoptyping
+%D
+%D At the cost of some overhead these alternatives are
+%D implemented using \type{\if}'s:
+
+\newif\ifbaselinerule \baselineruletrue
+\newif\ifbaselinefill \baselinefillfalse
+
+%D \macros
+%D {iftoprule,ifbottomrule,ifleftrule,ifrightrule}
+%D
+%D Rules can be turned on and off, but by default we have:
+%D
+%D \starttyping
+%D \topruletrue
+%D \bottomruletrue
+%D \leftruletrue
+%D \rightruletrue
+%D \stoptyping
+%D
+%D As we see below:
+
+\newif\iftoprule \topruletrue
+\newif\ifbottomrule \bottomruletrue
+\newif\ifleftrule \leftruletrue
+\newif\ifrightrule \rightruletrue
+
+%D \macros
+%D {boxrulewidth}
+%D
+%D The width in the surrounding rules can be specified by
+%D assigning an apropriate value to the dimension used. This
+%D module defaults the width to:
+%D
+%D \starttyping
+%D \boxrulewidth=.2pt
+%D \stoptyping
+%D
+%D Although we are already low on \DIMENSIONS\ it's best to
+%D spend one here, mainly because it enables easy manipulation,
+%D like multiplication by a given factor.
+
+\newdimen\boxrulewidth \boxrulewidth=.2pt
+
+%D The core macro \type{\makeruledbox} looks a bit hefty. The
+%D manipulation at the end is needed because we want to
+%D preserve both the mode and the baseline. This means that
+%D \type{\vtop}'s and \type{\vbox}'es behave the way we expect
+%D them to do.
+%D
+%D \startlinecorrection
+%D \hbox
+%D {\ruledhbox to 5em{\strut test\normalhss}\hskip1em
+%D \ruledvbox{\hsize 5em\strut test \par test\strut}\hskip1em
+%D \ruledvtop{\hsize 5em\strut test \par test\strut}}
+%D \stoplinecorrection
+%D
+%D The \type{\cleaders} part of the macro is responsible for
+%D the visual baseline. The \type{\normalhfill} belongs to this
+%D primitive too. By storing and restoring the height and depth
+%D of box \type{#1}, we preserve the mode.

+
+%D Just in case one didn't notice: the rules are in fact layed
+%D over the box. This way the contents of a box cannot
+%D visually interfere with the rules around (upon) it. A more
+%D advanced version of ruled boxes can be found in one of the
+%D core modules of \CONTEXT. There we take offsets, color,
+%D rounded corners, backgrounds and alignment into account too.
+
+%D \macros
+%D {ruledhbox,
+%D ruledvbox,ruledvtop,
+%D ruledvcenter}
+%D
+%D These macro's can be used instead of \type{\hbox},
+%D \type{\vbox}, \type{\vtop} and, when in math mode,
+%D \type{\vcenter}. They just do what their names state. Using
+%D an auxiliary macro would save us a few words of memory, but
+%D it would make their appearance even more obscure.

+%D \macros
+%D {ruledbox,

+%D
+%D Of the next two macros the first can be used to precede a
+%D box of ones own choice. One can for instance prefix boxes
+%D with \type{\ruledbox} and afterwards --- when the macro
+%D satisfy the needs --- let it to \type{\relax}.
+%D
+%D \starttyping
+%D \ruledbox\hbox{What rules do you mean?}
+%D \stoptyping
+%D
+%D The macro \type{\setruledbox} can be used to directly
+%D rule a box.
+%D
+%D \starttyping
+%D \setruledbox12=\hbox{Who's talking about rules here?}
+%D \stoptyping
+%D
+%D At the cost of some extra macros we can implement a
+%D variant that does not need the~\type{=}, but we stick to:
+
+\unexpanded\def\ruledbox
+ {\dowithnextbox{\makeruledbox\nextbox\box\nextbox}}
+
+\def\setruledbox#1=%
+ {\dowithnextbox{\makeruledbox\nextbox\setbox#1\nextbox}}
+
+%D \macros
+%D {investigateskip,
+%D investigatecount,
+%D investigatemuskip}
+%D
+%D Before we meet the visualizing macro's, we first implement
+%D ourselves some handy utility ones. Just for the sake of
+%D efficiency and readability, we introduce some status
+%D variables, that tell us a bit more about the registers we
+%D use:
+%D
+%D \starttyping
+%D \ifflexible
+%D \ifzero
+%D \ifnegative
+%D \ifpositive
+%D \stoptyping
+%D
+%D These status variables are set when we call for one of the
+%D investigation macros, e.g.
+%D
+%D \starttyping
+%D \investigateskip\scratchskip
+%D \stoptyping

+%D Now the neccessary utility macros are defined, we can make a
+%D start with the visualizing ones. The implementation of these
+%D macros is a compromise between readability, efficiency of
+%D coding and processing speed. Sometimes we do in steps what
+%D could have been done in combination, sometimes we use a few
+%D boxes more or less then actually needed, and more than once
+%D one can find the same piece of rule drawing code twice.
+
+%D \macros
+%D {ifcenteredvcue,normalvcue}
+%D
+%D Depending on the context, one can force visual vertical cues
+%D being centered along \type{\hsize} or being put at the
+%D current position. Although centering often looks better,
+%D we've chosen the second alternative as default. The main
+%D reason for doing so is that often when we don't set the
+%D \type{\hsize} ourselves, \TEX\ takes the value of the
+%D surrounding box. As a result the visual cues can migrate
+%D outside the current context.
+%D
+%D This behavior is accomplished by a small but effective
+%D auxiliary macro, which behavior can be influenced by the
+%D boolean \type{\centeredvcue}. By saying
+%D
+%D \starttyping
+%D \centeredvcuetrue
+%D \stoptyping
+%D
+%D one turns centering on. As said, we turn it off.
+
+\newif\ifcenteredvcue \centeredvcuefalse
+
+\def\normalvcue#1%
+ {\normalhbox \ifcenteredvcue to \hsize \fi {\normalhss#1\normalhss}}
+
+%D We could have used the more robust version
+%D
+%D \starttyping
+%D \def\normalvcue%
+%D {\normalhbox \ifcenteredvcue to \hsize \fi
+%D \bgroup\bgroup\normalhss
+%D \aftergroup\normalhss\aftergroup\egroup
+%D \let\next=}
+%D \stoptyping
+%D
+%D or the probably best one:
+%D
+%D \starttyping
+%D \def\normalvcue%
+%D {\hbox \ifcenteredvcue to \hsize
+%D \bgroup\bgroup\normalhss
+%D \aftergroup\normalhss\aftergroup\egroup
+%D \else
+%D \bgroup
+%D \fi
+%D \let\next=}
+%D \stoptyping
+%D
+%D Because we don't have to preserve \CATCODES\ and only use
+%D small arguments, we stick to the first alternative.
+
+%D \macros
+%D {testrulewidth}
+%D
+%D We build our visual cues out of rules. At the cost of a much
+%D bigger \DVI\ file, this is to be prefered over using
+%D characters (1)~because we cannot be sure of their
+%D availability and (2)~because their dimensions are fixed.
+%D
+%D As with ruled boxes, we use a \DIMENSION\ to specify the
+%D width of the ruled elements. This dimension defaults to:
+%D
+%D \starttyping
+%D \testrulewidth=\boxrulewidth
+%D \stoptyping
+%D
+%D Because we prefer whole numbers for specifying the
+%D dimensions, we often use even multiples of
+%D \type{\testrulewidth}.
+
+%D \macros
+%D {visiblestretch}
+%D
+%D A second variable is introduced because of the stretch
+%D components of \SKIPS. At the cost of some accuracy we can
+%D make this stretch visible.

+%D
+%D We start with the easiest part, the fills. The scheme we
+%D follow is {\em visual filling -- going back -- normal
+%D filling}. Visualizing is implemented using \type{\cleaders}.
+%D Because the \BOX\ that follows this command is constructed
+%D only once, the \type{\copy} is not really a prerequisite. We
+%D prefer using a \type{\normalhbox} here instead of a
+%D \type{\hbox}.

+%D Skips differ from kerns in two important aspects:
+%D
+%D \startitemize[packed]
+%D \item line and pagebreaks are allowed at a skip
+%D \item skips can have a positive and/or negative
+%D stretchcomponent
+%D \stopitemize
+%D
+%D Stated a bit different: kerns are fixed skips at which no
+%D line or pagebreak can occur. Because skips have a more open
+%D character, they are visualized in a open way.

+%D When skips have a stretch component, this is visualized by
+%D means of a dashed line. Positive skips are on top of the
+%D baseline, negative ones are below it. This way we can show
+%D the combined results. An alternative visualization of
+%D stretch could be drawing the mid line over a length of the
+%D stretch, in positive or negative direction.

+%D \macros
+%D {penalty}
+%D
+%D After presenting fills, skip, kerns and glue we've come to
+%D see penalties. In the first implementation --- most of the
+%D time needed to develop this set of macros went into testing
+%D different types of visualization --- penalties were mere
+%D small blocks with one black half, depending on the sign.
+%D This most recent version also gives an indication of the
+%D amount of penalty. Penalties can go from less than $-10000$
+%D to over $+10000$, and their behavior is somewhat
+%D non-lineair, with some values having special meanings. We
+%D therefore decided not to use its value for a lineair
+%D indicator.

+%D The small sticks at the side of the penalty indicate it
+%D size. The next example shows the positive and negative
+%D penalties of 0, 1, 10, 100, 1000 and 10000.

+%D \type{\dontshowcomposition} best can be called when we enter
+%D this routine. Too much visual cues just don't make sense. In

+%D Lets end with some more advanced examples.
+%D Definitions and enumerations come in many flavors. The
+%D next one for instance is defined as:
+%D
+%D \starttyping
+%D \definedescription[test][place=left,hang=3,width=6em]
+%D \stoptyping
+%D
+%D When applied to some text, this would look like:
+%D
+%D \bgroup
+%D \showmakeup
+%D \definedescription[test][location=left,hang=3,width=6em]
+%D
+%D \test{visual\\debugger} I would be very pleased if \TEX\
+%D had two more primitives: \type{\vnop} and \type{\hnop}. Both
+%D should act and show up as normal boxes, but stay invisible
+%D for \TEX\ when it's doing calculations. The \type{\vnop}
+%D for instance should not interact with the internal mechanism
+%D responsible for the disappearing skips, kerns and penalties
+%D at a pagebreak. As long as we don't have these two boxtypes,
+%D visual debugging will never be perfect.
+%D
+%D \egroup
+%D
+%D The index to this section looks like:
+%D
+%D {\setupreferencing[prefixprefix=dummy]\showmakeup\placeindex[criterium=local]}
+%D
+%D Although not impressive examples or typesetting, both
+%D show us how and where things happen. When somehow the last
+%D lines in this two column index don't allign, then this is
+%D due to some still unknown interference.
