+%D Color support is not present in \TEX. Colorful output can
+%D however be accomplished by using specials. This also means
+%D that this support depends on the \DVI\ driver used. At the
+%D moment this module was written, still no decent standard on
+%D color specials has been agreed upon. We therefore decided to
+%D implement a mechanism that is as independant as possible of
+%D drivers.
+%D
+%D Color support shares with fonts that is must be implemented
+%D in a way that permits processing of individual \DVI\ pages.
+%D Furthermore it should honour grouping. The first condition
+%D forces us to use a scheme that keeps track of colors at
+%D page boundaries. This can be done by means of \TEX's
+%D marking mechanism (\type{\mark}).
+%D
+%D When building pages, \TEX\ periodically looks at the
+%D accumulated typeset contents and breaks the page when
+%D suitable. At that moment, control is transfered to the
+%D output routine. This routine takes care of building the
+%D pagebody and for instance adds headers and footers. The page
+%D can be broken in the middle of some colored text, but
+%D headers and footers are often in black upon white or
+%D background. If colors are applied there, they definitely
+%D are used local, which means that they don't cross page
+%D borders.
+%D
+%D Boxes are handled as a whole, which means that when we
+%D apply colors inside a box, those colors don't cross page
+%D boundaries, unless of course boxes are split or unboxed.
+%D Especially in interactive texts, colors are often used in
+%D such a local way: in boxes (buttons and navigational tools)
+%D or in the pagebody (backgrounds).
+%D
+%D So we can distinguish local colors, that don't cross
+%D pages from global colors, of which we can end many pages
+%D later. The color macros will treat both types in a different
+%D way, thus gaining some speed.
+%D
+%D This module also deals with gray scales. Because similar
+%D colors can end up in the same gray scale when printed in
+%D black and white, we also implement a palet system that deals
+%D with these matters. Because of fundamental differences
+%D between color and gray scale printing, in \CONTEXT\ we also
+%D differ between these. For historic reasons |<|we first
+%D implemented gray scales using patterns of tiny periods|>|
+%D and therefore called them {\em rasters}. So don't be
+%D surprised if this term shows up.

+%D \macros
+%D {definecolor}
+%D {}
+%D
+%D We will enable users to specify colors in \kap{RGB} and
+%D \kap{CMYK} color spaces or gray scales using
+%D
+%D \showsetup{\y!definecolor}
+%D
+%D For example:
+%D
+%D \starttypen
+%D \definecolor [SomeKindOfRed] [r=.8,g=.05,b=.05]
+%D \stoptypen
+%D
+%D Such color specifications are saved in a macro in the
+%D following way:
+%D
+%D \starttypen
+%D \setvalue{\??cr name}{R:r:g:b}
+%D \setvalue{\??cr name}{C:c:m:y:k}
+%D \setvalue{\??cr name}{K:k}
+%D \stoptypen
+%D
+%D Gray scales are specified with the \type{k} parameter,
+%D the same as used in \kap{CMYK} specifications.

+%D The names of colors are stored in a comma separated list
+%D only for the purpose of showing them with \type{\showcolor}.
+%D
+%D Colors can be defined global by using \type{\doglobal},
+%D like in
+%D
+%D \startbuffer
+%D \doglobal\definecolor [SomeKindOfRed] [r=.8,g=.05,b=.05]
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \haalbuffer
+%D
+%D This color shows up as \color[SomeKindOfRed]{some kind
+%D of red}.
+
+%D \macros
+%D {setupcolor}
+%D {}
+%D
+%D Color definitions can be grouped in files with the name:
+%D
+%D \starttypen
+%D \f!colorprefix-identifier.tex
+%D \stoptypen
+%D
+%D where \type{\f!colorprefix} is {\tttf \f!colorprefix}. Loading
+%D such a file is done by
+%D
+%D \showsetup{\y!setupcolor}
+%D
+%D Some default colors are specified in \type{colo-rgb.tex},
+%D which is loaded into the format by:
+%D
+%D \starttypen
+%D \setupcolor[rgb]
+%D \stoptypen
+
+\def\colorstyle{}

+ {\showmessage{\m!colors}{4}{\colorstyle}}
+ {\showmessage{\m!colors}{5}{\colorstyle}}}%
+ \processcommalist[#1]\dodosetupcolor}}
+
+%D When typesetting for paper, we prefer using the \kap{CMYK}
+%D color space, but for on||screen viewing we prefer \kap{RGB}
+%D (the previous implementation supported only this scheme).
+%D Independant of such specifications, we support some automatic
+%D conversions:
+%D
+%D \startopsomming[opelkaar]
+%D \som convert all colors to \kap{RGB}
+%D \som convert all colors to \kap{CMYK}
+%D \som convert all colors to gray scales
+%D \stopopsomming
+%D
+%D We also support optimization of colors to gray scales.
+%D
+%D \startopsomming[verder]
+%D \som reduce gray colors to gray scales
+%D \stopopsomming
+%D
+%D These options are communicated by means of:
+
+\newif\ifRGBsupported
+\newif\ifCMYKsupported
+\newif\ifconverttoGRAY
+\newif\ifpreferGRAY
+\newif\ifGRAYprefered
+\newif\ifreduceCMYK
+
+%D The last boolean controls reduction of \kap{CMYK} to
+%D \kap{CMY} colors. When set to true, the black component
+%D is added to the other ones.
+
+%D Color modes are entered using the next set of commands.
+%D The \type{\stop} alternatives are implemented in a way
+%D that permits non||grouped use.

+%D Prefering gray is not the same as converting to gray. Conversion treats
+%D each color components in a different way, while prefering is just a
+%D reduction and thus a space||saving option.
+
+%D \macros
+%D {startcolormode,stopcolormode}
+%D
+%D We use \type{\stopcolormode} to reset the color in
+%D whatever color space and do so by calling the corresponding
+%D special. Both commands can be used for fast color
+%D switching, like in colored verbatim,
+

+%D unneccessary hash entries.

+%D We already mentioned that colors interfere with building
+%D the pagebody. This means that when the page is composed,
+%D the colors temporary have to be reset. After the page is
+%D shipped out, we have to revive the current color.
+%D
+%D We use \type{\marks} to keep track of colors across page
+%D boundaries. Unfortunately standard \TEX\ supports only one mark,
+%D and using this one for color support only would be a waste.
+%D We therefore use an adapted version of J.~Fox's multiple mark
+%D mechanism as (re|)|implemented in \module{supp-mrk}.
+
+\doifdefinedelse{newmark}
+ {\newmark\colormark}
+ {\def\colormark#1{}}
+
+%D Using this mark mechanism with lots of colors has one
+%D major drawback: \TEX's memory tends to overflow when
+%D very colorful text is stored in a global box. Even worse is that
+%D the processing time grows considerably. We therefore support
+%D local as well as global color switching.
+%D
+%D Of the next macros, \type{\popcolor} is to be used after
+%D the actual \type{\shipout} and \type{\startcolorpage} and
+%D \type{\stopcolorpage} are called when entering and leaving
+%D the \type{\pagebody} builder. In case of emergencies
+%D \type{\pushcolor} can be used to undo the current color,
+%D for instance when insertions are appended to the page.
+
+%D Before we present the color macros, we first define the
+%D setup command. This command takes care of setting up the
+%D booleans that control local and global behavior and
+%D conversion to other color spaces.

+%D In this documentation we will not go into too much details
+%D on palets. Curious users can find more information on this
+%D topic in \uit[use of color].
+%D
+%D At the moment we implemented color in \CONTEXT\ color
+%D printing was not yet on the desktop. In spite of this lack our
+%D graphics designer made colorfull illustrations. When printed
+%D on a black and white printer, distinctive colors can come
+%D out equally gray. We therefore decided to use only colors
+%D that were distinctive in colors as well as in black and
+%D white print.
+%D
+%D Although none of the graphic packages we used supported
+%D logical colors and global color redefition, we build this
+%D support into \CONTEXT. This enabled us to experiment and
+%D also prepared us for the future.

+%D Just to give users a start we define some colors. While
+%D switching fonts is as international as can be, thanks to the
+%D mnemonics, naming colors is very interface dependant. To
+%D support international setups, we define both english and
+%D interface dependant colors. We use the color inheritance
+%D mechanisms to implement the interface dependant ones.
+
+%D First we define some simple primary \kap{RGB} and \kap{CMYK}
+%D colors. All colors are defined in \kap{RGB} color space.

+%D Welcome to the main module. When this module is ran through
+%D \type{initex} or \type{tex -i} or \type{whatevertex} using
+%D \type{whatever switch}, the \CONTEXT\ format file is
+%D generated. During this process the user is asked for an
+%D interface language. Supplying \type{dutch} will generate a
+%D dutch version of \CONTEXT, supplying \type{english} will of
+%D course end op in a english version.
+%D
+%D First we load the system modules. These implement a lot of
+%D manipulation macros. The first one loads \PLAIN\ \TEX, as
+%D minimal as possible.
+
+\input syst-tex.tex
+\input syst-gen.tex
+\input syst-ext.tex
+\input syst-new.tex
+
+%D After this we're ready for the multi||lingual interface
+%D modules.
+
+\input mult-ini.tex
+\input mult-sys.tex
+\input mult-con.tex
+\input mult-com.tex
+
+%D Now we're ready for some general support modules. These
+%D modules implement some basic typesetting functionality.
+
+\input supp-ini.tex
+\input supp-fil.tex
+\input supp-ver.tex
+\input supp-box.tex
+\input supp-mrk.tex
+\input supp-vis.tex
+\input supp-mul.tex
+\input supp-fun.tex
+\input supp-pdf.tex
+\input supp-spe.tex
+\input supp-mps.tex
+\input supp-tpi.tex
+
+%D \CONTEXT\ does not implement its own table handling. We
+%D just go for the best there is and load \TABLE. Just to be
+%D sure we do it here, before we redefine \type{|}.
+
+\doinputonce{table}
+
+%D Here comes the last support module.
+
+\input supp-lan.tex
+
+%D The next three modules do what their names state. They
+%D load additional definition modules when needed.
+
+\input lang-ini.tex
+\input spec-ini.tex
+\input colo-ini.tex
+
+%D For the moment we load a lot of languages. In the future
+%D we'll have to be more space conservative.
+
+\input lang-lab.tex
+
+\input lang-alt.tex
+\input lang-ana.tex
+\input lang-art.tex
+\input lang-bal.tex
+\input lang-cel.tex
+\input lang-ger.tex
+\input lang-grk.tex
+\input lang-hnl.tex
+\input lang-ind.tex
+\input lang-ita.tex
+\input lang-sla.tex
+\input lang-ura.tex
+
+%D The special modules need some additional macro's:
+
+\input spec-mis.tex
+
+%D Next we load some core macro's. These implement the
+%D macros' that are seen by the users.
+
+\input core-gen.tex
+\input core-mak.tex
+\input core-fil.tex
+\input core-ver.tex
+\input core-vis.tex
+\input core-con.tex
+\input core-rul.tex
+\input core-tab.tex
+\input core-fil.tex
+\input core-01a.tex
+
+%D Of course we do need fonts. There are no \TFM\ files
+%D loaded yet, so the format file is independant of their
+%D content. Here we also redefine \type{\it} as {\it italic}
+%D instead of italian.
+
+\input font-ini.tex
+
+%D Now we're ready for more core modules.
+
+\input core-fnt.tex
+\input core-not.tex
+
+\input core-01b.tex
+\input core-01c.tex
+\input core-01d.tex
+\input core-01e.tex
+
+\input core-02a.tex
+\input core-02b.tex
+% core-02c.tex
+\input core-02d.tex
+
+%D Except from english, no hyphenation pattersn are loaded
+%D yet. Users can specify their needs in the next module:
+
+\input cont-usr.tex
+
+%D The next two modules implement some additional
+%D functionality concenring classes of documents and output.
+%D These modules probably will be replaced some day.
+
+\input docs-ini.tex
+\input list-ini.tex
+
+%D \TEX\ related logo's are always typeset in a special way.
+%D Here they come:
+
+\input cont-log.tex
+
+%D Dumping the format is all that's left to be done.

+%I n=Struts

+%I Struts zijn onzichtbare 'karakters' met alleen een hoogte
+%I en diepte. De volgende commando's hebben betrekking op
+%I struts
+%I
+%I \strut
+%I \setstrut
+%I \setnostrut
+%I \toonstruts
+
+\def\toonstruts%
+ {\setteststrut}
+
+% Hieronder volgen enkele instellingen en macro's ten behoeve
+% van de interlinie en \strut. De waarden 2.8, 0.07, 0.72 en
+% 0.28 zijn ooit eens ontleend aan INRS-TEX en moeten wellicht
+% nog eens instelbaar worden.
+%
+% \lineheight : de hoogte van een regel
+% \spacing{getal} : instellen interlinie
+% \normalbaselines : instellen regelafstend
+%
+% \setstrut : instellen \strut
+% \setnostrut : resetten \strut, \endstrut, \begstrut
+%
+% \setteststrut : instellen zichtbare struts
+% \resetteststrut : instellen onzichtbare struts
+%
+% \setfontparameters : instellen na fontset
+%
+% De hoogte van een regel (\lineheight) is gelijk aan de
+% som van de hoogte (\ht) en diepte (\dp) van \strutbox.
+%
+% \strut : denkbeeldig blokje met hoogte en diepte
+%
+% Een \hbox kan als deze aan het begin van een regel staat
+% een breedte \hsize krijgen. Dit is soms te voorkomen met het
+% commando \leavevmode. Binnen een \vbox geeft dit echter
+% niet altijd het gewenste resultaat, vandaar het commando
+%
+% \leaveoutervmode
+
+% Pas op: niet zomaar \topskip en \baselineskip aanpassen
+% en zeker niet \widowpenalty. Dit kan ernstige gevolgen
+% hebben voor kolommen.
+%
+% Enige glue kan op zich geen kwaad, echter als blanko=vast,
+% dan moet ook de rek 0 zijn. Binnen kolommen is rek ook
+% niet bepaald mooi. Een hele kleine waarde (0.025) voldoet,
+% omdat een positieve glue eindeloos rekbaar is.

+% Algemeen
+%
+% De Pragma-macros zijn samengesteld met behulp van de
+% commandos van PlainTeX- en enkele TugBoat routines.
+%
+% Voor de volledigheid zijn in de definitie steeds de
+% {}-haakjes vermeld. Deze haakjes zijn niet altijd
+% nodig, Als bijvoorbeeld een paragraaf bewerkt wordt,
+% kunnen ze achterwege blijven.
+%
+% Instellingen worden opgegeven tussen []-haakjes,
+% meestal direct na het commando. Instellingen mogen
+% soms achterwege blijven.
+%
+% Een aantal veelgebruikte macro's zijn in TeXEdit op
+% naam en/of door middel van een mnemonic oproepbaar.
+

+% %I c=\steloffsetin
+% %I
+% %I De totale bladzijde kan verschoven worden ten opzichte
+% %I van de linkerbovenhoek met:
+% %I
+% %I \steloffsetin[rug=,kop=]
+% %I
+% %I Dit commando moet worden gegeven aan het begin van de
+% %I pagina waarvoor het moet gelden. Er kunnen positieve
+% %I en negatieve waarden worden ingevuld: -10pt, 1.5cm.

+%I n=Zetspiegel
+%I c=\stellayoutin,\definieerpapierformaat,\stelpapierformaatin
+%I c=\paslayoutaan
+%I
+%I De zetspiegel is het door de tekst gevormde vlak.
+%I Hiertoe behoren ��k de hoofd- en voetmarge. De zetspiegel
+%I wordt ingesteld met:
+%I
+%I \stellayoutin[breedte=,hoogte=,rugwit=,kopwit=]
+%I
+%I Er dienen maten te worden ingevuld, waarbij de eenheid
+%I direkt achter het getal staat: 10pt, 100mm, 5cm, 3.5in.
+%I
+%I De parameters hebben de volgende betekenis:
+%I
+%I breedte breedte van het tekstvlak, inclusief marges
+%I hoogte hoogte van het tekstvlak, inclusief marges
+%I rugwit witruimte aan de binnenzijde, zonder marge
+%I kopwit witruimte aan de bovenzijde, zonder marge
+%P
+%I Rond de zetspiegel vinden we marges, randen, het hoofd en
+%I de voet. Ook deze worden ingesteld met:
+%I
+%I \stellayoutin[breedte=,hoogte=,rugwit=,kopwit=]
+%I
+%I hoofd hoogte van de bovenmarge binnen de zetspiegel
+%I voet hoogte van de ondermarge binnen de zetspiegel
+%I marge breedte van de marge naast de zetspiegel
+%I
+%I en
+%I
+%I rand breedte van de rand naast de marge
+%I boven hoogte van de rand boven het hoofd
+%I onder hoogte van de rand onder de voet
+%I
+%I Alleen het hoofd en de voet hangen dus samen met de
+%I zetspiegel.
+%P
+%I Eventueel kunnen de linker- en rechtermarge en apart
+%I worden ingesteld:
+%I
+%I \stellayoutin[linkermarge=,rechtermarge=]
+%I
+%I Het zelfde geldt voor de randen. In dat geval wordt bij
+%I dubbelzijdig zetten gespiegeld. Oppassen dus!
+%I
+%I De afstanden tussen marges, randen enz. kunnen worden
+%I ingesteld met:
+%I
+%I bovenafstand, onderafstand
+%I hoofdafstand,voetafstand
+%I linkermargeafstand,rechtermargeafstand,
+%I linkerrandafstand,rechterrandafstand
+%P
+%I De zetspiegel kan (tijdelijk) worden aangepast met het
+%I commando:
+%I
+%I \paslayoutaan[hoogte=]
+%I
+%I Men dient een positieve (+) of negatieve (-) maat op te
+%I geven. De zethoogte blijft gelijk, maar de teksthoogte
+%I wordt aangepast ten koste van de voethoogte. Eventueel
+%I kan 'max' worden opgegeven.
+%I
+%I Er kan een reeks aanpassingen worden opgegeven:
+%I
+%I \paslayoutaan[nr,nr,nr,...][hoogte=]
+%I
+%I Hierbij is staat nr voor het paginanummer, dat wil
+%I zeggen: het volgnummer in de tekst.
+%I
+%I Bij voorlopige versies wordt onderaan de pagina de
+%I aanpassing weergegeven.
+%P
+%I Beeldmerken en achtergronden worden uit oogpunt van
+%I verwerkingssnelheid niet vaker berekend dan nodig. Mocht
+%I om een of andere reden een beeldmerk of achtergrond niet
+%I overeenkomen komen met de wensen, dan kan herberekenen
+%I worden geforceerd met:
+%I
+%I \stellayoutin[reset]
+%P
+%I Het papierformaat is in te stellen met het commando
+%I
+%I \stelpapierformaatin[DIN-formaat]
+%I
+%I Mogelijke DIN-formaten zijn A4 tot en met A9. De
+%I afmetingen van een A4 zijn:
+%I
+%I breedte : 21.0cm = 8.18in = 589pt
+%I hoogte : 29.7cm = 11.58in = 834pt
+%I
+%I Optioneel kan men het printer papierformaat instellen door
+%I een tweede argument mee te geven. Standaard wordt
+%I uitgegaan van A4.
+%I
+%I \stelpapierformaatin[A5][A4]
+%I
+%P Men kan zelf een papierformaat definieren met
+%I
+%I \definieerpapierformaat [naam] [hoogte=,breedte=]
+%I
+%I waarbij de offset betrekking heeft op dubbelzijdig zetten.

+%I n=Uitstellen
+%I c=\steluit,\startuitstellen
+%I
+%I Zetcommando's kunnen in een wachtrij worden gezet en na
+%I een pagina worden uitgevoerd. Dit gebeurt met het commando:
+%I
+%I \startuitstellen
+%I ...
+%I \stopuitstellen
+%I
+%I of
+%I
+%I \steluit{...}
+%I
+%I Dit kan handig zijn bij bijvoorbeeld grote tussen te voegen
+%I figuren, tabellen, formulieren enz.
+%I
+%I \startuitstellen
+%I \plaatsfiguur[pagina][]{...}{...}
+%I \stopuitstellen
+%I
+%I Er kunnen meerdere commando's in de wachtrij worden
+%I geplaatst.
+%P
+%I Het mechanisme werkt nog niet vlekkeloos. Zo wordt
+%I nog gerekend met waarden van de vorige pagina. Dit heeft
+%I bijvoorbeeld als gevolg dat figuren kunnen worden
+%I opgespaard.
+%I
+%I Het kan gebeuren dat een (te) groot figuur er voor zorgt
+%I dat ook andere figuren worden verplaatst. De volgorde
+%I blijft immers gehandhaafd. In dat geval kan zo'n groot
+%I figuur worden verplaatst naar de eerstvolgende voor de
+%I handliggende pagina:
+%I
+%I \startuitstellen
+%I \plaatsfiguur[pagina][]{...}{...}
+%I \pagina
+%I \stopuitstellen

+%I
+%I De afstand tussen paragrafen is in te stellen met:

+%I
+%I In te vullen op de plaats van 'maat' (12pt, 1cm) of een

+%I
+%I Voor elke lege regel in de ASCII-file voegt TEX de
+%I ingestelde witruimte tussen.
+%I
+%I Het commando \witruimte dwingt witruimte af en het
+%I commando \geenwitruimte maakt witruimte ongedaan.
+%I
+%I Behalve met de hier beschreven witruimte-commando's is de
+%I witruimte tussen paragrafen te be�nvloeden met behulp van

+%I de elders beschreven witruimte-commando's.
+%I
+%I Het commando
+%I
+%I \blanko[sprong]
+%I
+%I voegt witruimte tussen paragrafen toe.
+%I
+%I Mogelijke instellingen voor 'sprong' zijn: terug, klein,
+%I middel, groot. Per blanko is elke combinatie van
+%I instellingen toegestaan. Ook een veelvoud van een instelling
+%I is mogelijk. Enkele voorbeelden:
+%I
+%I \blanko[terug,3*groot]
+%I \blanko[klein,middel]
+%P
+%I Naast de genoemde instellingen zijn enkele bijzondere
+%I instellingen mogelijk:
+%I
+%I wit tussenvoegen van \witruimte
+%I geenwit terugspringen van \witruimte
+%I blokkeer overslaan van de volgende \blanko
+%I reset opheffen van \blanko[blokkeer]
+%I forceer afdwingen van een blanko (bovenaan)
+%I
+%I Ook deze instellingen zijn in combinatie met andere te
+%I gebruiken. Een voorbeeld: \blanko[forceer,wit,2*middel].
+%I
+%I Het commando \blanko (zonder instelling) is gelijk aan
+%I \blanko[groot].
+%I
+%I Het commando \geenblanko maakt het commando \blanko
+%I ongedaan.
+%P
+%I Met het commando's
+%I
+%I \stelblankoin[maat]
+%I
+%I is het mogelijk de spronggrootte in te stellen. De maat
+%I kan worden opgegeven in getallen en eenheden (12pt, 1cm).
+%I De standaard instellingen krijgt met met 'normaal',
+%I regelafstanden met 'regel'.
+%I
+%I Het commando \stelblankoin (zonder argument) past de sprong
+%I aan het formaat letter aan.
+%P
+%I Rond omlijnde tekst, of algemener: rond lijnen, wordt
+%I geen witruimte gegenereerd. Wil men dit wel, dan dient men
+%I de betreffende tekst te omringen met:
+%I
+%I \startregelcorrectie
+%I \stopregelcorrectie
+
+% In earlier versions \type{\bigskipamount} was
+% \type{\ht\strutbox} and the stretch was plus or minus
+% \type{.4\dp\strutbox}. Don't ask me why. The most recent
+% implementation is based on a user supplied distance, which
+% is by default \type{.75\normalskipamount} where
+% \type{\normalskipamount} equals the current baseline

+%I gebruiken:
+%I
+%I ditiseen|---|heellangwoord|--|hoeweleigenlijkis|-|heteenzin
+%I
+%I Het is ook mogelijk geen teken mee te geven:
+%I
+%I ditiseen||heellangwoord
+%I
+%I In dat geval wordt het ingestelde teken tussengevoegd. Het
+%I teken kan worden ingesteld met:
+%I
+%I \stelkoppeltekenin[teken=]
+%I
+%I Betekenisvolle waarden zijn: - en --, eventueel kan ~
+%I worden meegegeven. In dat geval wordt een \thinspace
+%I geplaatst.
+%P
+%I Een |~| levert midden in de zin een spatie en aan het
+%I eind van de zin een streepje, || is standaard equivalent
+%I met |--|.
+%I
+%I Het koppelteken zelf kan worden opgeroepen met |=|,
+%I bijvoorbeeld in alfa|=| en beta||deeltjes. Dit levert
+%I dus alfa- en beta-deeltjes of alfa-- en beta--deeltjes.
+%I Andere instellingen worden afgevangen.
+%I
+%I Ook ( en ) worden afgevangen. Hierbij wordt bij het
+%I afbreken van voor(na) op de volgende regel (-na)
+%I geplaatst. En wat te denken van |<| en |>|.

+% - meerdere niveaus (moet niet moeilijk zijn)
+% - instellingen in macro
+
+%I n=Opsomming
+%I c=\startopsomming,\som,\sub,\kop,\sym,\mar,\but
+%I c=\stelopsommingin
+%I
+%I Opsommingen kunnen tot op vier niveaus automatisch worden
+%I aangemaakt met het commando:
+%I
+%I \startopsomming[aanduiding][instellingen]
+%I
+%I \som ........
+%I \som ........
+%I \som[referentie] ........
+%I \som ........
+%I
+%I \stopopsomming
+%I
+%I Eventueel kan direct achter \som een [referentie] worden
+%I opgegeven, zodat men bijvoorbeeld kan verwijzen naar
+%I 'punt \in[referentie]' (hier punt 3).
+%P
+%I De volgende genummerde aanduidingen zijn mogelijk:
+%I
+%I wijze van 'nummeren' instelling
+%I
+%I 1, 2, 3, 4 n (normaal) / o (oldstyle)
+%I a, b, c, d a
+%I A, B, C, D A (normaal) / KA (kap)
+%I i, ii, iii, iv r
+%I I, II, III, IV R (normaal) / KR (kap)
+%I
+%I doornummeren verder
+%P
+%I De volgende niet-genummerde aanduidingen zijn mogelijk
+%I (de aanduiding kan eventueel achterwege blijven):
+%I
+%I wijze van 'markeren' instelling
+%I
+%I dot 1
+%I streepje 2
+%I sterretje 3
+%I driehoekje 4
+%I bolletje 5
+%I groter bolletje 6
+%I nog groter bolletje 7
+%I
+%I alleen inspringen leeg laten
+%P
+%I Het al dan niet inspringen en de eventuele ruimte tussen
+%I de onderdelen wordt globaal of lokaal ingesteld met de
+%I commando's:
+%I
+%I \stelopsommingin[niveau][instelling]
+%I
+%I waarbij de volgende instellingen mogelijk zijn:
+%I
+%I standaard standaard instellingen
+%I opelkaar geen witruimte tussen onderdelen
+%I aanelkaar weinig witruimte na het symbool
+%I aansluitend geen wit voor en na de opsomming
+%I ruim meer witruimte na het symbool (n*ruim)
+%I inmarge markering in de kantlijn
+%I opmarge markering op de 'kantlijn'
+%I afsluiter afsluiter achter markering
+%I kolommen in twee kolommen zetten
+%I intro aansluiten op vorige regel(s)
+%P
+%I In plaats van een cijfer bij niveau kan ook het woord
+%I 'elk' worden gegeven. De instellingen mogen ook direkt
+%I achter de aanduiding worden meegegeven: [1,opelkaar].
+%I
+%I Als alternatief voor \som is \kop beschikbaar. In dat geval
+%I wordt de eerste alinea (of een eerste woord) afwijkend gezet.
+%I
+%I Met \sym{symbool} kan een eigen symbool worden geplaatst.
+%I Als dit symbool breed is (bijvoorbeeld ++), kan men de
+%I breedte aanpassen, bijvoorbeeld: \startopsomming[2*ruim].
+%I
+%I Een ander alternatief is \mar{tekst}. De tekst wordt in
+%I dat geval in de marge geplaatst.
+%I
+%I Een leeg item (dus zonder aanduiding) kan worden
+%I opgeroepen met \nop. Op deze manier kunnen opsommingen in
+%I kolommen worden uitgelijnd (gemanipuleerd). Het commando
+%I \nop komt overeen met \sym{\strut} \strut.
+%P
+%I Met \som[aanduiding] (zonder \start... \stop...) kan snel een
+%I opsomming met ��n item worden gezet. In dat geval wordt er
+%I geen referentie aangemaakt.
+%I
+%I Als men een item tussenvoegt maar (vooralsnog) de nummering
+%I niet wil verhogen, dan kan men \sub gebruiken. Het oude nummer
+%I wordt dan in het zetwerk voorafgegaan door een +.
+%I
+%I Interactieve items kunnen worden gemaakt met \but, waarbij
+%I de bestemming tussen [] moet worden meegegeven.
+%P
+%I Een nauwkeuriger (globale) instelling is eveneens mogelijk met
+%I het commando:
+%I
+%I \stelopsommingin[niveau][breedte=,voor=,tussen=,na=,
+%I kopvoor=,kopna=,kopletter=,marletter=,symlettter=,
+%I afsluiter=,n=,factor=,afstand=]
+%I
+%I Standaard gelden voor de letters de volgende instellingen:
+%I
+%I kopletter normaal
+%I marletter type
+%I symletter vet
+%I
+%I De commando's \sym{symbool} en \som zijn ook buiten
+%I opsommingen beschikbaar.

+%I n=Doordefinieren
+%I c=\doordefinieren,\steldoordefinierenin
+%I
+%I Er kunnen (eenvoudige) definitie-lijsten worden
+%I gemaakt met behulp van het commando:
+%I
+%I \doordefinieren[naam][plaats=,breedte=,uitlijnen=,
+%I monster=,letter=,kopletter=,voor=,tussen=,na=,hang=,
+%I inspringen=,tekst=]
+%I
+%I Een definitie is vervolgens op naam op te roepen:
+%I
+%I \naam{begrip} definitie
+%P
+%I Een definitie heeft de vorm:
+%I
+%I links Dit is een linker tekst. Een tekst wordt
+%I links geplaatst als 'links' wordt meegegeven.
+%I
+%I Dit is een rechter tekst. Een tekst wordt rechts
+%I rechts geplaatst als 'rechts' wordt meegegeven.
+%I
+%I boven
+%I
+%I Dit is een tekst waarbij het woord erboven staat. Voor
+%I dit soort teksten wordt 'boven' meegegeven.
+%I
+%I Tot slot is het mogelijk de tekst in de marge of
+%I aansluitend te plaatsen, in dat geval wordt 'inmarge',
+%I 'inlinker', 'inrechter' of 'aanelkaar' meegegeven.
+%P
+%I Aan 'voor', 'tussen' of 'na' kan een commando worden
+%I toegekend, bijvoorbeeld \blanko[groot]. Als letter kan
+%I normaal, vet, kapitaal, type, schuin, klein en kleinvet
+%I worden meegegeven.
+%I
+%I Als 'breedte' kan een maat worden meegegeven of een van de
+%I instellingen 'passend' en 'ruim'. In dat geval wordt de
+%I aan 'monster' toegekende tekst als uitgangspunt genomen.
+%P
+%I Met 'hang' kan men aangeven hoe lang er links of rechts
+%I moet worden ingesprongen. Er kan een aantal regels worden
+%I meegegeven maar ook 'passend' of 'ruim'. Een overgang naar
+%I een nieuwe regel binnen een linker- of rechtertekst wordt
+%I afgedwongen met \\ (vergelijk \margeteksten).
+%I
+%I Defaultwaarden kunnen worden ingesteld met het commando:
+%I
+%I \steldoordefinierenin[instellingen]
+%I
+%I Het tussentijds bijstellen van de instellingen is mogelijk
+%I met:
+%I
+%I \steldoordefinieren[naam][instellingen]
+

+%I n=Doornummeren
+%I c=\doornummeren,\steldoornummerenin
+%I c=\reset,\volgende,\vorige
+%I
+%I Het is mogelijk door een tekst heen genummerde opsommingen
+%I te gebruiken. Het beschikbare commando is:
+%I
+%I \doornummeren[naam][plaats=,niveaus=,conversie=,
+%I kopletter=,letter=,breedte=,monster=,tekst=,voor=,tussen=,
+%I na=,wijze=,blok=,scheider=,afsluiter=,hang=,links=,rechts=,
+%I sectienummer=,nummer=,koppeling=,uitlijnen=,inspringen]
+%I
+%I De naam bestaat uit letters.
+%I
+%I Na het commando 'doornummeren' zijn de volgende commando's
+%I beschikbaar:
+%I
+%I \naam
+%I \subnaam
+%I \subsubnaam
+%I
+%I waarbij naam staat voor de opgegeven naam.
+%P
+%I Dit commando komt in grote lijnen overeen met het
+%I commando \doordefinieren. Als de plaats 'links' is
+%I en de tekst is 'vraag', dan krijgen we na het
+%I geven van \vraag Wat ... was?:
+%I
+%I vraag 1 Wat zouden we krijgen als de plaats 'rechts'
+%I en de tekst 'antwoord' was?
+%I
+%I We kunnen een referentie meegeven, dus \vraag[ref]. Als
+%I we geen nummer willen, maar wel de tekst, dan is de
+%I aanroep \vraag[-]. Er wordt in dat geval niet opgehoogd.
+%I Hetzelfde kan worden bereikt door 'nummer' de waarde
+%I nee te geven.
+%P
+%I De wijze waarop het laatste niveau wordt weergegeven kan
+%I worden ingesteld met conversie: cijfers, letters, Letters,
+%I romeins en Romeins). Conversie heeft pas effect als ook
+%I niveaus is ingesteld (2 of 3, standaard 3).
+%I
+%I Voor of na de te nummeren tekst op te nemen commando's
+%I kunnen worden ingesteld. Ook kan een voor het nummer op te
+%I nemen tekst worden meegegeven en kan de plaats van de tekst
+%I en het nummer worden ingesteld (� la \doordefinieren!).
+%I
+%I Er kan een koppeling worden gelegd met een ander item. Zo
+%I kunnen bijvoorbeeld vragen worden gekoppeld aan antwoorden.
+%I Dergelijke koppelingen hebben pas betekenis bij
+%I interactieve teksten.
+%I
+%I Defaultwaarden kunnen worden ingesteld met het commando:
+%I
+%I \steldoornummerenin[instellingen]
+%P
+%I Het is mogelijk het nummeren opnieuw te starten met het
+%I commando:
+%I
+%I \reset<naam>
+%I
+%I en een (sub)nummer op te hogen met:
+%I
+%I \volgende<naam>
+%I \volgendesub<naam>
+%I
+%I Het tussentijds bijstellen van de instellingen is mogelijk
+%I met:
+%I
+%I \steldoornummerenin[naam][instellingen]

+%I Het is mogelijk genummerde verwijzingen (bijvoorbeeld
+%I naar sheets of video's) in de tekst op te nemen met
+%I het commando:
+%I
+%I \doorlabelen[naam][tekst=,plaats=,voor=,na=,kopletter=]
+%I
+%I Na dit commando zijn de volgende commando's beschikbaar:
+%I
+%I \reset<naam>
+%I \verhoog<naam>
+%I \volgende<naam>[referentie]
+%I \huidige<naam>
+%I \in<naam>[referentie]
+%P
+%I Er kan een 'kopje' worden opgeropeen met het commando:
+%I
+%I \naam
+%I
+%I In dat geval worden de onder 'voor' en 'na' opgegeven
+%I commando's uitgevoerd.
+%I
+%I Als we voor naam 'sheet' invullen en voor tekst
+%I 'transparant' dan leidt het commando \huidigesheet tot
+%I de tekst 'transparant 1' en een volgende aanroep tot de
+%I tekst 'transparant 2'.

+%I n=Margeteksten
+%I c=\inmarge,\inlinker,\inrechter,\stelinmargein
+%I c=\margetitel,\figuurinmarge
+%I c=\oplinker
+%I
+%I Een paragraaf kan worden ingeluid met een tekst in
+%I de marge:
+%I
+%I \inmarge{tekst}
+%I \inlinker{tekst}
+%I \inrechter{tekst}
+%I
+%I Met \\ kan binnen een margetekst naar een volgende regel
+%I worden gesprongen.
+%P
+%I Het onderstaande commando kan gebruikt worden om een
+%I paragraafaanduiding in de marge te plaatsen. Het commando
+%I moet aan het begin van de paragraaf staan. Er wordt
+%I gecontroleerd of een en ander nog op de bladzijde past.
+%I
+%I \margetitel{tekst}
+%I
+%I Tussen \margetitel{tekst} en de volgende alinea mag,
+%I omwille van de overzichtelijkheid, een lege regels staan.
+%I Als dit commando wordt gebruikt na een commando als
+%I \paragraaf, kan het controlemechanisme leiden tot een
+%I ongewenste overgang naar een nieuwe bladzijde. In dat
+%I geval kan beter het volgende commando worden gebruikt.
+%I
+%I \margewoord{tekst}
+%I
+%I Dit commando komt overeen met \inmarge, alleen is bij
+%I \margewoord de lege regel toegestaan.
+%P
+%I Er kan eventueel voor {tekst} een [referentie] worden
+%I meegegeven. In dat geval kan worden verwezen naar het
+%I paginanummer waarop het margewoord staat.
+%I
+%I Als TeX twijfelt in welke marge het woord moet staan, is
+%I een tweede verwerkingsslag nodig. Als een margewoord bij
+%I herhaling verkeerd wordt geplaatst, dan kan het
+%I automatisme worden verstoord door [+] mee te geven. Een
+%I margewoord kan lager worden gezet met [laag]. Combinaties
+%I kunnen ook:
+%I
+%I \margewoord[+,laag][referentie]{woord}
+%P
+%I De wijze van weergeven kan worden ingesteld met het
+%I commando:
+%I
+%I \stelinmargein[letter=,plaats=,voor=,na=,uitlijnen=]
+%I
+%I Als plaats kan links, rechts of beide worden meegegeven. In
+%I het laatste geval hangt de plaats af van het
+%I enkel/dubbelzijdig zetten.
+%I
+%I Uitlijnen kent twee instellingen: 'ja' en 'nee'. Inhet
+%I eerste geval (default) worden de margewoorden tegen de
+%I kantlijn geplaatst.
+%P
+%I Vooruitlopend op meer commando's is er al vast het
+%I commando:
+%I
+%I \oplinker{tekst}
+%I
+%I Dit commando kan bijvoorbeeld worden gebruikt binnen
+%I een midden-uitgelijnde tekst. Het commando is nog niet
+%I definitief en robuust.
+
+% %P
+% %I Aanvullend zijn commando's beschikbaar om figuren in
+% %I de marge te plaatsen:
+% %I
+% %I \figuurinmarge{figuur}
+% %I \figuurinlinker{figuur}
+% %I \figuurinrechter{figuur}

+%D We want to keep things efficient and therefore only handle
+%D situations like:
+%D
+%D \startbuffer
+%D \inleftside {fine} some text \par
+%D \strut \inleftmargin {fine} some text \par
+%D \noindent \inrightmargin {fine} some text \par
+%D \noindent \strut \inrightside {fine} some text \par
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D which looks like:
+%D
+%D \bgroup
+%D \haalbuffer
+%D \parindent 30pt
+%D \haalbuffer
+%D \egroup
+
+%D \macros
+%D {pushindentation,popindentation}
+%D
+%D The pushing and popping is done by:
+
+\newbox\indentationboxA
+\newbox\indentationboxB
+
+\def\pushindentation%
+ {\bgroup
+ \ifhmode
+ \unskip
+ \setbox\indentationboxA=\lastbox % get \strut if present
+ \unskip
+ \setbox\indentationboxB=\lastbox % get \indent generated box
+ \unskip
+ \else
+ \hskip\!!zeropoint % switch to horizontal mode
+ \unskip
+ \setbox\indentationboxA=\lastbox % get \indent generated box
+ \setbox\indentationboxB=\box\voidb@x
+ \fi}
+
+\def\popindentation%
+ {\box\indentationboxB\box\indentationboxA % put back the boxes
+ \egroup}
+
+%D The only complication lays in \type{\strut}. In \PLAIN\
+%D \TEX\ a \type{\strut} is defined as:
+%D
+%D \starttypen
+%D \def\strut%
+%D {\relax\ifmmode\copy\strutbox\else\unhcopy\strutbox\fi}
+%D \stoptypen
+%D
+%D But what is a \type{\strut}? Normally it's a rule of width
+%D zero, but when made visual, it's a rule and a negative skip.
+%D The mechanism for putting things in the margins described
+%D here cannot handle this situation very well. One
+%D characteristic of \type{\strut} is that the \type{\unhcopy}
+%D results in entering horizontal mode, which in return leads
+%D to some indentation.
+%D
+%D To serve our purpose a bit better, the macro \type{\strut}
+%D can be redefined as:
+%D
+%D \starttypen
+%D \def\strut%
+%D {\relax\ifmmode\else\hskip0pt\fi\copy\strutbox}
+%D \stoptypen
+%D
+%D Or more compatible:
+%D
+%D \starttypen
+%D \def\strut%
+%D {\relax\ifmmode
+%D \copy\strutbox
+%D \else
+%D \bgroup\setbox\strutbox=\normalhbox{\box\strutbox}\unhcopy\strutbox\egroup
+%D \fi}
+%D \stoptypen
+%D
+%D In \CONTEXT\ however we save some processing time by putting
+%D an extra \type{\hbox} around the \type{\strutbox}.

+%I c=\stelhoofdtekstenin,\stelvoettekstenin,\stelhoofdin,\stelvoetin
+%I c=\stelboventekstenin,\stelondertekstenin,\stelbovenin,\stelonderin
+%I
+%I Zogeheten hoofd- en/of voetteksten kan men instellen
+%I met:
+%I
+%I \stelhoofdtekstenin [linker tekst] [rechter tekst]
+%I \stelvoettekstenin [linker tekst] [rechter tekst]
+%I
+%I Bij dubbelzijdig zetten worden de linker en rechter
+%I teksten gespiegeld.
+%I
+%I In plaats van een tekst kunnen de woorden 'hoofdstuk',
+%I 'paragraaf' en 'deel' worden meegegeven. Ook kan het
+%I woord 'datum' worden meegegeven.
+%P
+%I Als men op de even en oneven pagina's een andere tekst
+%I wil hebben, dan kan men een tweede paar meegeven. In dat
+%I geval zijn er dus vier argumenten: [][][][].
+%I
+%I Als men in de marge of randen teksten wil, kan men dat
+%I direct achter het commando aangeven:
+%I
+%I \stelhoofdtekstenin [lokatie] [links] [rechts]
+%I \stelvoettekstenin [lokatie] [links] [rechts]
+%I
+%I Mogelijke lokaties zijn: tekst, marge en rand.
+%P
+%I In de tekst opgenomen commando's kunnen soms voor
+%I problemen zorgen. Commando's kan men daarom laten
+%I voorafgaan \geentest, bijvoorbeeld:
+%I
+%I \stelvoettekstenin[\geentest\lastigcommando][]
+%I
+%I Meestal geven commando's geen problemen. Wel moet men
+%I oppassen met []. Accolades zijn hiervoor de oplossing:
+%I
+%I \stelvoettekstenin[{{\huidigedatum[mm,/,jj]}}][]
+%I
+%I of
+%I
+%I \stelvoettekstenin[\geentest{\huidigedatum[mm,/,jj]}][]
+%P
+%I De wijze van nummeren wordt gedefinieerd met:
+%I
+%I \stelnummeringin[variant=,plaats=,conversie=,
+%I links=,rechts=,tekst=,tekstscheider=,nummerscheider,
+%I wijze=,blok=,status=,letter=,<sectie>nummer=,commando=]
+%I
+%I De plaats van het nummer hangt af van het eerste
+%I meegegeven argument:
+%I
+%I enkelzijdig dubbelzijdig
+%I
+%I links, rechts kantlijn (links of rechts)
+%I marge marge (links of rechts)
+%I midden midden
+%I inlinker, inrechter inlinker, inrechter
+%P
+%I Met plaats geeft men tevens aan of het nummer in het hoofd
+%I of in de voet komt {hoofd,midden}. Met 'nummerscheider' geeft
+%I men aan wat er binnen een (eventueel) samengestelde nummer
+%I als scheider wordt gezet, standaard: 2-3. Met 'tekstscheider'
+%I geeft men aan wat er tussen het paginanummer en een hoofd- of
+%I voettekst wordt gezet (in geval van plaatsen op de marge).
+%I
+%I Liefhebbers kunnen aan 'commando' een eigen commando om het
+%I nummer te zetten meegeven. Dit eigen commando krijgt als
+%I argument het paginanummer mee.
+%I
+%I Het is mogelijk een dubbelzijdige tekst met enkelzijdige
+%I marges te zetten:
+%I
+%I \stelnummeringin[variant={enkelzijdig,dubbelzijdig}]
+%I
+%I In dit geval worden de hoofd- en voetregels dus wel
+%I gespiegeld en hebben commando's als \pagina[rechts] betekenis.
+%P
+%I Als 'conversie' is mogelijk: cijfers, letters, Letters,
+%I romeins en Romeins. Als 'status' kan 'start' of 'stop'
+%I worden meegegeven. Op deze manier kan het aangeven van
+%I een paginanummer worden aan- en uitgezet.
+%I
+%I Er kan per sectienummer (deelnummer, hoofdstuknummer enz.)
+%I worden ingesteld of het zichtbaar is ('ja' of 'nee').
+%I
+%I Mogelijke wijzen van nummeren zijn: perdeel of perhoofdstuk.
+%P
+%I Hoofd- en voetregels blijven achterwege of juist niet na het
+%I commando:
+%I
+%I \geenhoofdenvoetregels
+%I \welhoofdenvoetregels
+%I
+%I of na:
+%I
+%I \stelhoofdin[lokatie][linkerletter=,rechterletter=,
+%I letter=,linkerbreedte=,rechterbreedte=,voor=,na=]
+%I \stelvoetin[locatie][linkerletter=,rechterletter=,
+%I letter=,linkerbreedte=,rechterbreedte=,voor=,na=]
+%I
+%I mogelijke lokaties zijn: tekst, marge en rand. Als [lokatie]
+%I wordt wegelaten, dan wordt tekst verondersteld.
+%I
+%I Als de breedte wordt ingesteld, dan wordt de weergegeven
+%I tekst zonodig ingekort en gevolgd door ...
+%P
+%I Het is mogelijk het plaatsen van hoofd- en voetregels
+%I stop te zetten:
+%I
+%I \stelhoofdin[status=]
+%I \stelvoetin[status=]
+%I
+%I Aan status kunnen de olgende aarden worden toegekend:
+%I
+%I geen de kop/voet vervalt (de tekst schuift omhoog)
+%I leeg de kop/voet blijft 1 pagina leeg
+%I hoog de kop/voet vervalt 1 pagina leeg (idem)
+%I normaal de kop/voet wordt gezet
+%I stop de kop/voet blijft vanaf nu leeg
+%I start de kop/voet wordt vanaf nu weer gevuld
+%I
+%I Het is ook mogelijk bij \stelhoofdin en \stelvoetin als
+%I parameters [voor=] en [na=] mee te geven. De toegekende
+%I commando's worden in dat geval voor en na het hoofd en de
+%I de voet uitgevoerd.
+%P
+%I Boven het hoofd en onder de voet is ook ruimte. Deze kan
+%I worden gedefinieerd met vergelijkbare commando's:
+%I
+%I \stelboventekstenin[...][...][...]
+%I \stelondertekstenin[...][...][...]
+%I
+%I \stelbovenin[...]
+%I \stelonderin[...]
+%I
+%I \geenbovenenonderregels
+%I \welbovenenonderregels
+
+% De onderstaande macro's lijken op het eerste gezicht vrij
+% ingewikkeld en omslachtig. Dit is het gevolg van een
+% dubbel optioneel zijn van argumenten: zowel het eerste als
+% de twee laatste argumenten zijn optioneel. Dit is mede het
+% gevolg van een uitbreiding naar marges en randen, waarbij
+% upward-compatibiliteit zwaar heeft gewogen.

+%I
+%I Men kan in een tekst markeringen aanbrengen. Een markering
+%I kan bijvoorbeeld worden opgehaald in een kopregel.
+%I
+%I \definieermarkering[categorie]
+%I
+%I Een markering wordt aangebracht met het commando:
+%I
+%I \markeer[categorie]{tekst}
+%I
+%I Er kunnen drie markeringen worden opgevraagd met het
+%I commando:
+%I
+%I \haalmarkering[categorie][plaats]
+%I
+%I Mogelijke plaatsen zijn: eerste, laatste, vorige. Vorige
+%I staat voor de laatste markering op de vorige bladzijde en
+%I eerste en laatste hebben betrekking op de huidige bladzijde.
+%P
+%I Markeringen worden ge(de)blokkeerd met het commando:
+%I
+%I \stelmarkeringin[categorie][status=,expansie=]
+%I
+%I waarbij als instellingen mogelijk zijn: start en stop.
+%I Standaard wordt een markering niet ge�xpandeerd. Wil met
+%I wel expanderen (wat bij tellers nodig is), dan kan dat
+%I worden ingesteld: expansie=ja.
+%I
+%I Markeringen kunnen worden geinitialiseerd met:
+%I
+%I \resetmarkering[categorie]
+%I
+%I Standaard worden de markeringen 'deel', 'hoofdstuk', 'paragraaf',
+%I 'subparagraaf' en 'subsubparagraaf bijgehouden.
+%P
+%I Soms wordt een argument voor meerdere doeleinden gebruikt,
+%I bijvoorbeeld in \hoofdstuk{tekst}. Hierbij is {tekst}
+%I zowel de kop van het hoofdstuk als de eventueel te plaatsen
+%I markering in de hoofd- of voetregel. Als zo'n tekst te lang
+%I wordt, kan ze als volgt worden beperkt:
+%I
+%I {eerste tweede \geenmarkering{derde vierde} vijfde}
+%I
+%I De woorden 'derde' en 'vierde' worden in dit geval in de
+%I markering vervangen door punten.
+
+% Het commando \newmark\markering genereert
+%
+% \markering
+%
+% en het commando \getmarks\markering genereert
+%
+% \topmarkering
+% \botmarkering
+% \firstmarkering
+%
+% voor 'interne' doeleinden zijn beschikbaar:
+%
+% \prefetchmark[naam]
+% \fetchmark[naam][plaats]

+%I c=\stelkopin,\stelkoppenin,\stelkopnummerin
+%I c=\startbijlagen,\bijlage
+%I c=\startinleidingen,\startuitleidingen
+%I
+%I Een tekst wordt gestructureerd met de commando's:
+%I
+%I \titel [referentie] {titel}
+%I \onderwerp [referentie] {onderwerp}
+%I \subonderwerp [referentie] {onderwerp}
+%I \subsubonderwerp [referentie] {onderwerp}
+%I
+%I \hoofdstuk [referentie] {titel}
+%I \paragraaf [referentie] {titel}
+%I \subparagraaf [referentie] {titel}
+%I \subsubparagraaf [referentie] {titel}
+%I
+%I In een {titel} kan het commando \\ worden gebruikt om naar
+%I een volgende regel te gaan. Wil men ook in de inhoudsopgave
+%I naar een nieuwe regel gaan, dan dient \crlf te worden
+%I gebruikt.
+%P
+%I Op een hoger niveau kunnen delen worden gedefinieerd. In
+%I dat geval wordt standaard geen kop geplaatst (het kan
+%I wel).
+%I
+%I \deel [referentie] {titel}
+%I
+%I In totaal zijn er 7 niveaus voorgedefinieerd. Meer
+%I niveaus zijn mogelijk. Het hoogste niveau is op dit
+%I moment dus \deel en het laagste \subsubsubsubparagraaf.
+%P
+%I Naar een hoofdstuk en een paragraaf kan worden
+%I terugverwezen met:
+%I
+%I \inhoofdstuk[referentie]
+%I \inparagraaf[referentie]
+%I
+%I Zodat verwijzingen als 'zie ook hoofdstuk 2' mogelijk
+%I zijn (zie ook \inhoofdstuk[alfa]).
+%I
+%I Ook kunnen de elders besproken commando's worden
+%I gebruikt. Een referentie kan eventueel worden weggelaten,
+%I bijvoorbeeld \hoofdstuk{titel}.
+%P
+%I Een overgang naar een nieuwe alinea kan worden afgedwongen
+%I met het commando:
+%I
+%I \alinea
+%I
+%I Dit commando komt overeen met het commando \par.
+%P
+%I Aanvullend zijn de volgende commando's beschikbaar. Deze
+%I commando's onderdrukken cq. wijzigen de nummering.
+%I
+%I \startbijlagen hoofdstukken nummeren met a, b, ...
+%I \stopbijlagen hoofdstukken nummeren met 1, 2, ...
+%I
+%I \startinleidingen hoofdstukken niet nummeren
+%I \stopinleidingen hoofdstukken wel nummeren
+%I \startuitleidingen hoofdstukken niet nummeren
+%I \stopuitleidingen hoofdstukken wel nummeren
+%I
+%I Als men bijlagen apart wil nummeren, dan gebruikt men in
+%I plaats van \hoofdstuk het commando:
+%I
+%I \bijlage[referentie]{titel}
+%I
+%I waarna de eigenlijke tekst komt of wordt ingelezen uit
+%I een file.
+%P
+%I De wijze waarop hoofdstukken en paragrafen worden genummerd
+%I en gezet, kan worden ingesteld met de commando's:
+%I
+%I \stelkoppenin[variant=,scheider=]
+%I
+%I Hierbij zijn als varianten mogelijk normaal en inmarge.
+%I
+%I Daarnaast is het volgende commando beschikbaar:
+%I
+%I \stelkopin[element][letter=,nummerletter=,tekstletter=,
+%I voor=,na=,pagina=,uitlijnen=,hoofd=]
+%I
+%I Mogelijke elementen zijn: hoofdstuk, paragraaf,
+%I subparagraaf, subsubparagraaf en indien gewenst: titel en
+%I onderwerp.
+%P
+%I Aan de parameters voor en na kunnen commando's worden
+%I toegekend; 'nummer', 'tekst' en 'letter' staan voor de
+%I lettertypen. Standaard zijn 'nummer' en 'tekst' gelijk
+%I aan 'letter'. In de regel kan men volstaan met het
+%I instellen van hoofdstuk en paragraaf, omdat de andere
+%I instellingen hiervan worden afgeleid. Voorbeelden van
+%I instellingen zijn 'letter=vet', 'voor={\blanko[groot]}'
+%I en 'nummer=\tfa'.
+%I
+%I Aan 'pagina' kan de waarde 'links', 'rechts' of 'ja' worden
+%I toegekend. Er wordt alleen naar een nieuwe pagina gegaan als
+%I het nummer van de (sub)(sub)paragraaf groter is dan 1.
+%I Wil men altijd overgaan op een nieuwe bladzijde, dan kan
+%I men dit aangeven door aan 'doorgaan' de waarde 'nee' toe
+%I te kennen.
+%P
+%I Een hoofdstuk kan worden voorafgegaan door een woord,
+%I bijvoorbeeld 'Hoofdstuk'. Dit woord kan worden ingesteld
+%I met \stellabeltekstin.
+%I
+%I Als men aan 'hoofd' de waarde 'geen' toekent, dan wordt
+%I geen hoofdregel geplaatst op de bladzijde waarop de kop
+%I wordt geplaatst.
+%I
+%I Het is mogelijk varianten van koppen te definieren met het
+%I commando:
+%I
+%I \definieerkop[dochter][moeder]
+%I
+%I Na \definieerkop[rubriek][onderwerp] is het commando \rubriek
+%I beschikbaar met dezelfde kenmerken als \onderwerp. Deze
+%I kenmerken kunnen worden aangepast met \stelkopin. Als de
+%I moeder een genummerde kop is, wordt de dochter ook genummerd.
+%P
+%I Nummers van koppen kunnen worden ingesteld met het commando:
+%I
+%I \stelkopnummerin[niveau][nummer]
+%I
+%I Als het nummer wordt vooraf gegaan door + of -, dan is
+%I sprake van een verhoging of verlaging: [hoofdstuk][+2].
+

+%T m=hfd

+%I n=Verwijzingen
+%I c=\in,\op,\referentie,\stelrefererenin,\gebruikreferenties
+%I
+%I In elders gedefinieerde commando's opgegeven referenties
+%I kunnen worden opgeroepen met:
+%I
+%I \in[referentie]
+%I \op[referentie]
+%I
+%I Soms kunnen ook commando's als \infiguur[referentie] en
+%I \inhoofdstuk[referentie] worden gebruikt. Bovendien is
+%I het commando \oppagina[referentie] beschikbaar.
+%I
+%I Een verwijzing naar een pagina kan worden aangemaakt met:
+%I
+%I \tekstreferentie[referentie]{nummer of tekst}
+%I \paginareferentie[referentie]
+%I \referentie[referentie]{nummer of tekst}
+%P
+%I Er kunnen tegelijk meerdere referenties worden opgegeven:
+%I
+%I \tekstreferentie[ref1,ref2,ref3]{nummer of tekst}
+%I
+%I Dit kan overigens overal waar een [referentie] kan worden
+%I meegegeven, bijvoorbeeld bij hoofdstukken.
+%P
+%I Het refereren kan (tijdelijk) worden stopgezet met het
+%I commando:
+%I
+%I \stelrefererenin[status=,<sectie>nummer=,prefix=]
+%I
+%I waarbij 'start' en 'stop' mogelijke waarden zijn voor
+%I status. Een sectienummer (deelnummer, hoofdstuknummer
+%I enz.) kan 'ja of 'nee' zijn.
+%I
+%I Om verwarring te voorkomen kunnen binnen subdocumenten die

+%I
+%I Het is mogelijk de indeling in regels zoals die in de ruwe
+%I tekst wordt gehanteerd af te dwingen. Er wordt in dit
+%I geval niet ingesprongen. De regels worden gezet tussen de
+%I twee commando's:
+%I
+%I \startregels
+%I
+%I ...................................................
+%I
+%I \stopregels
+%P
+%I Er kan met betrekking tot regels een en ander worden
+%I ingesteld:
+%I
+%I \stelregelsin[voor=,na=,inspringen=]
+%I
+%I Aan 'inspringen' kan men 'ja', 'nee', 'even' of 'oneven'
+%I toekennen.
+%P
+%I Het is mogelijk regels te nummeren door ze tussen de
+%I volgende commando's te plaatsen:
+%I
+%I \startregelnummeren
+%I \stopregelnummeren
+%I
+%I Als de regelovergangen moeten worden gehandhaafd, dan moet
+%I \startregels voor \startregelnummeren worden gegeven.
+%I
+%I Het nummeren begint steeds opnieuw bij 1. Als verder moet
+%I worden genummeren, dan kan achter \startregelnummeren
+%I [verder] worden meegegeven.
+%I
+%I Standaard worden regels alinea-gewijs genummerd. Als men
+%I over een paginagrens wil nummeren, dan moet [opelkaar]
+%I worden meegegeven.
+%P
+%I De wijze van nummeren kan worden ingesteld met:
+%I
+%I \stelregelnummerenin[conversie=,start=,stap=,letter=,
+%I plaats=,breedte=,letter=]
+%I
+%I Als 'conversie' kan worden meegegeven: cijfers, letters,
+%I Letters, romeins of Romeins. Aan 'start' en 'stap' kan
+%I een getal worden toegekend, aan 'letter' een trefwoord,
+%I aan 'breedte' een maat (bij voorkeur in ex) en aan
+%I 'plaats' het trefwoord 'inmarge' of 'intekst'.
+%P
+%I Er kan worden overgegaan naar een nieuwe regel met:
+%I
+%I \crlf
+%P
+%I .... testfase ...
+%I
+%I \startregel[tag] ... \stopregel[tag]
+%I \eenregel[tag]

+%I n=Opmaak
+%I c=\definieeropmaak,\testopmaak,\startstandaardopmaak
+%I
+%I Het is mogelijk een lege pagina op te maken. Hiertoe wordt
+%I een blok gereserveerd met het commando:
+%I
+%I \definieeropmaak[naam][breedte=,hoogte=,voffset=,
+%I hoffset=,pagina=,commandos=,voor=,na=,dubbelzijdig=]
+%I
+%I Hierbij wordt bij de eerste vier parameters een getal
+%I meegegeven (5cm, 24pt, enz.). Met 'pagina' geeft men aan
+%I of naar een nieuwe pagina wordt gesprongen (standaard
+%I 'rechts'). Aan de 'commandos' kunnen commando's worden
+%I toekend die tijdens de opmaak gelden. Aan de laatste twee
+%I parameters toegekende commando's worden voor en na het
+%I opmaken van de pagina uitgevoerd. De opgemaakte pagina
+%I kan worden geselecteerd op naam. Met 'dubbelzijdig' geeft
+%I men aan of er een lege achterkant moet worden opgemaakt
+%I (standaard: ja). Dit geldt aleen bij dubbelzijdig zetten.
+%I
+%I Naast het bovenstaande commando is er het commando:
+%I
+%I \stelopmaakin[naam][instellingen]
+%P
+%I Na het geven van dit commando zijn twee commando's
+%I beschikbaar: \startnaamopmaak en \stopnaamopmaak. Tussen
+%I deze twee commando's kunnen zetopdrachten en teksten
+%I worden opgenomen. Een en ander wordt op een lege bladzijde
+%I gezet.
+%I
+%I Met het commando \testopmaak kunnen hulplijnen worden
+%I opgeroepen.
+%I
+%I De commando's \startstandaardopmaak en \stopstandaardopmaak
+%I maken het opmaken binnen de standaard-layout mogelijk.
+%P
+%I Eventueel kunnen de volgende twee commando's worden gebruikt
+%I om een pagina op te maken met hoofd- en voetregels.

+%I
+%I \hbox?{tekst} (horizontaal blok)
+%I
+%I De box wordt eerst gedefinieerd met:

+%I n=Blokken
+%I c=\stelplaatsblokkenin,\stelblokkopjesin
+%I c=\definieerplaatsblok,\stelplaatsblokin
+%I c=\reserveer,\leeg,\plaats,\volledigelijstmet,\plaatslijstmet
+%I
+%I Figuren, tabellen, grafieken enz. kunnen in de tekst
+%I worden geplaatst met het commando:
+%I
+%I \plaats<bloknaam>[voorkeur][referentie]{titel}{blok}
+%I
+%I Als voorkeur kan worden opgegeven:
+%I
+%I hier bij voorkeur op deze plaats in de tekst
+%I forceer per se op deze plaats in de tekst
+%I pagina op een nieuwe pagina
+%I boven bovenaan de huidige pagina
+%I onder onderaan de huidige pagina
+%I
+%I links links in de paragraaf
+%I rechts rechts in de paragraaf
+%I
+%I inlinker in linker marge (gelijke hoogte)
+%I inrechter in rechter marge (gelijke hoogte)
+%I inmarge in linker/rechter marge (gelijke hoogte)
+%I marge in de marge
+%P
+%I Als er op de huidige bladzijde geen plaats is, dan wordt
+%I standaard de figuur verplaatst (eerste vier opties) en/of
+%I wordt overgegaan naar een nieuwe bladzijde (laatste twee
+%I opties.
+%I
+%I Men kan plaatsen afdwingen door het trefwoord altijd
+%I mee te geven: \plaats[hier,altijd][]{}{}. Er zijn dan
+%I twee runs nodig, omdat de nummering van de blokken moet
+%I worden aangepast.
+%I
+%I Als in plaats van een titel 'geen' wordt meegegeven, wordt
+%I geen titel geplaatst.
+%I
+%I Als het blok nog onbekend is, kan in plaats van het blok
+%I een van de volgende commando's worden meegegeven:
+%I
+%I \leeg<bloknaam>
+%I \lege<bloknaam>
+%P
+%I Het is mogelijk ruimte voor een blok te reserveren:
+%I
+%I \reserveer<bloknaam>[hoogte=,breedte=,kader=][voorkeur]
+%I [referentie]{titel}
+%I
+%I Beide commando's kunnen ook gegeven worden zonder [],
+%I dus in de vorm
+%I
+%I \plaats<bloknaam>{titel}{blok}
+%I \reserveer<bloknaam>{titel}
+%I
+%I Ten behoeve van een consistente verwijzing wordt het
+%I commando:
+%I
+%I \in<bloknaam>[referentie]
+%I
+%I gedefinieerd. Dit levert in de tekst op:
+%I
+%I 'in <bloknaam> <nummer>'
+%P
+%I Blokken kunnen worden gedefinieerd met het commando:
+%I
+%I \definieerplaatsblok[blok][blokken]
+%I
+%I Hierna zijn de volgende commando's beschikbaar:
+%I
+%I \plaatsblok[plaats][referentie]{titel}{blok}
+%I \reserveerblok[afmetingen][plaats][referentie]{titel}
+%I \leegblok
+%I
+%I Het is mogelijk een en ander in te stellen met het
+%I commando:
+%I
+%I \stelplaatsblokin[blok][hoogte=,breedte=,kader=,
+%I bovenkader=,onderkader=,linkerkader=,rechterkader=,
+%I paginaovergangen=]
+%I
+%I De hoogte en breedte hebben betrekking op de te reserveren
+%I ruimte.
+%P
+%I Naast de eerder genoemde commando's zijn nog beschikbaar:
+%I
+%I \plaatslijstmetblokken
+%I \volledigelijstmetblokken
+%I
+%I en een (extra) commando om tekst naast een blok (hier met
+%I de naam 'blok') te plaatsen:
+%I
+%I \startbloktekst[plaats][referentie]{kop}{blok}
+%I ...
+%I \stopbloktekst
+%I
+%I Mogelijke plaatsen zijn 'links', 'rechts', 'hoog', 'laag' en
+%I 'midden'. Ook is een combinatie van deze instellingen
+%I mogelijk, bijvoorbeeld [links,hoog]. De instelling 'offset'
+%I resulteert in een verschuiving van 1 regel.
+%P
+%I Blokken die tussen de tekst staan kunnen links, rechts of in
+%I het midden worden uitgelijnd. De plaats wordt ingesteld met:
+%I
+%I \stelplaatsblokkenin[plaats=,breedte=,kader=,bovenkader=,
+%I onderkader=,linkerkader=,rechterkader=,offset=,voorwit=,
+%I nawit=,marge=]
+%I
+%I De genummerde kopjes bij blokken kunnen worden ingesteld
+%I met:
+%I
+%I \stelblokkopjesin[plaats=,voor=,tussen=,na=,letter=,
+%I kopletter=,breedte=,nummer=,uitlijnen=]
+%I
+%I waarbij als plaats kan worden meegegeven: 'boven', 'onder',
+%I 'geen', 'hoog', 'laag' of 'midden'. Als breedte kan 'passend'
+%I of 'max' worden meegegeven. De parameter nummer kan 'ja' of
+%I 'nee' zijn. Als breedte=max, dan wordt het kopje over de
+%I hele breedte geplaatst. In dat geval kan uitlijnen worden
+%I ingesteld: 'links', 'midden' of 'rechts'.
+%P
+%I Als er geen plaats is, worden plaatsblokken tijdelijk
+%I achtergehouden. De opgespaarde blokken worden op de
+%I volgende bladzijde(n) geplaatst. Dit plaatsen is te
+%I beinvloeden met:
+%I
+%I \stelplaatsblokkenin[nboven=,nonder=,nregels=]
+%I
+%I Standaard worden maximaal 2 blokken bovenaan de
+%I bladzijde geplaatst en 0 blokken onder. Er wordt overgegaan
+%I op een nieuwe bladzijde als het aantal regels groter is
+%I dan 4. Deze waarden kunnen worden ingesteld.
+%P
+%I Kopjes boven lijsten en labels voor nummers kunnen worden
+%I ingesteld met de elders beschreven commando's:
+%I
+%I \stellabeltekstin[label=...]
+%I \stelkoptekstin[tekst=...]
+%I
+%I Standaard zijn deze ingesteld op de opgegeven namen.

+%I Figuren en tabellen (gebruik ..tabel.. in plaats van
+%I ..figuur..) kunnen in de tekst worden geplaatst met het
+%I commando:
+%I
+%I \plaatsfiguur[plaats][referentie]{titel}{figuur}
+%I
+%I Als voorkeur kan worden opgegeven 'hier', 'forceer',
+%I 'pagina', 'boven', 'onder', 'links' en 'rechts'. In plaats
+%I van een titel kan 'geen' worden meegegeven, in dat geval
+%I wordt geen titel geplaatst. Eventueel kan in combinatie
+%I met links en rechts 'lang' worden opgegeven.
+%I
+%I De volgorde kan worden afgedwongen met 'altijd',
+%I bijvoorbeeld [hier,altijd]. In dat geval wordt bij een
+%I volgende run zonodig de nummering aangepast.
+%I
+%I In plaats van een titel kan {geen} worden ingevuld. In
+%I dat geval blijft de titel achterwege.
+%P
+%I Het is mogelijk ruimte voor een figuur te reserveren:
+%I
+%I \reserveerfiguur[hoogte=,breedte=,kader=][voorkeur]
+%I [referentie]{titel}
+%P
+%I Een lijst met figuren kan worden opgeroepen met:
+%I
+%I \plaatslijstmetfiguren
+%I \volledigelijstmetfiguren
+%I
+%I Men kan een tekst naast een figuur zetten met:
+%I
+%I \startfiguurtekst[plaats][referentie]{kop}{figuur}
+%I ...
+%I \stopfiguurtekst
+%I
+%I Mogelijke plaatsen zijn (combinaties van) 'links', 'rechts',
+%I 'hoog', 'laag' en 'midden'. Met 'offset' dwingt men een
+%I verschuiving omlaag van van 1 regel af.

+%I Zie verder onder plaatsblokken.

+%I
+%I Formules kunnen in de tekst worden geplaatst met
+%I het commando:
+%I
+%I \plaatsformule[referentie]subnummer$$formule$$
+%I
+%I Dit commando handelt de witruimtes om de formules af en
+%I plaatst nummers. Als geen nummer nodig is, en dus ook
+%I geen referentie, dan moet met het commando als volgt
+%I gebruiken:
+%I
+%I \plaatsformule-$$...$$ of \plaatsformule[-]$$...$$
+%I
+%I Als het nummer niet moet worden opgehoogd, gebruikt men
+%I
+%I \plaatssubformule[referentie]subnummer$$formule$$
+%P
+%I PAS OP:
+%I
+%I Binnen een aantal wiskundige commando's, zoals
+%I \displaylines, moet men het nummer zelf plaatsen. Dit
+%I kan gebeuren met: \formulenummer of \subformulenummer.
+%I Ook hier kan een [referentie] en een {subnummer} worden
+%I meegegeven.
+%I
+%I \plaatsformule
+%I $$\displaylines
+%I {x \hfill\formulenummer[eerste]{}\cr
+%I y \hfill\cr
+%I z \hfill\formulenummer[derde]{}\cr}
+%I $$
+%P
+%I De wijze waarop formules worden genummerd kan worden
+%I be�nvloed door het commando:
+%I
+%I \stelformulesin[links=,rechts=,plaats=]
+%I
+%I De nummers kunnen links en rechts worden gezet. Standaard
+%I worden de symbolen ( en ) gebruikt.
+%I
+%I Tussen twee formules kan witruimte worden geforceerd met
+%I het commando:
+%I
+%I \blanko[formule]

+%I c=\definieerlijst,\stellijstin,\plaatslijst
+%I
+%I Er kunnen lijsten worden aangemaakt en opgeroepen. Een
+%I lijst wordt gedefinieerd met:
+%I
+%I \definieerlijst[naam]
+%I
+%I en zonodig ingesteld met:
+%I
+%I \stellijstin[naam][status=,variant=,marge=,breedte=,
+%I scheider=,afstand=,paginanummer=,deelnummer=,
+%I titeluitlijnen=,label=,letter=,tekstletter=,nummerletter=,
+%I paginaletter=,paginaovergangen=,voor=,na=,niveau=,
+%I criterium=,symbool=,prefix=,links=,rechts=]
+%I
+%I De instellingen mogen ook direkt worden opgegeven:
+%I
+%I \definieerlijst[naam][instellingen]
+%I
+%I Ook kunnen kenmerken van andere lijsten worden overgenomen:
+%I
+%I \definieerlijst[naam][andere naam]
+%P
+%I De vorm van de lijst wordt onder meer bepaald door de variant
+%I (a,b,c). In grote lijnen ziet een lijst er als volgt uit:
+%I
+%I <marge+breedte+scheider+afstand> <variant>
+%I
+%I Mogelijke varianten zijn:
+%I
+%I variant a : nummer - titel - pagina
+%I variant b : nummer - titel - spaties - pagina
+%I variant c : nummer - titel - punten - pagina
+%I variant d : nummer - titel - pagina (doorlopend)
+%P
+%I Een of meer lijsten kunnen wordt opgeroepen met:
+%I
+%I \plaatslijst[naam,naam,...]
+%I
+%I Standaard zijn lijsten gedefinieerd voor deel, hoofdstuk,
+%I paragraaf, subparagraaf en subsubparagraaf. Deze lijsten
+%I zijn dus afzonderlijk in te stellen. Deze lijsten zijn
+%I gegroepeerd tot een samengestelde lijst (zie elders).
+%I
+%I De layout van een lijst kan worden beinvloed door
+%I commando's tussen te voegen met:
+%I
+%I \schrijftussenlijst[naam]{commandos}
+%I
+%I Voor eigen gebruik is \iflijstgeplaatst beschikbaar.
+%P
+%I Gevorderde gebruikers kunnen eigen lijstcommando's maken.
+%I Deze commando's kunnen worden toegekend met:
+%I
+%I [...,nummercommando=,tekstcommando=,paginacommando=,...]
+%I
+%I en hebben de vorm
+%I
+%I \commando{argument}
+%I
+%I bijvoorbeeld
+%I
+%i nummercommando=\omlijnd
+%I
+%I Volledige vrijheid krijgt men met de instelling

+%I het niveau specificeren. Met 'niveau' geeft men aan tot welk

+%I n=Synoniemen

+%I
+%I Er kunnen meerdere lijsten worden gedefinieerd door middel
+%I van het commando:
+%I
+%I \definieersynoniemen[naam][namen][commando]
+%I
+%I Na dit commando zijn de volgende commando's beschikbaar:
+%I
+%I \naam{tekst}{synoniem}
+%I \commando{tekst}
+%I \volledigelijstmetnamen
+%I \plaatslijstmetnamen
+%P
+%I De commando's rond de lijst met afkortingen zijn gedefinieerd
+%I met de waarden: [afkorting][afkortingen][\voluit]. Beschikbare
+%I commando's zijn dus:
+%I
+%I \afkorting{afkorting}{betekenis}
+%I \voluit{afkorting}
+%I \volledigelijstmetafkortingen
+%I \plaatslijstmetafkortingen
+%I
+%I De betekenis kan worden opgeroepen met \voluit{afkorting}.
+%P
+%I De wijze van zetten kan worden ingesteld met het commando:
+%I
+%I \stelsynoniemenin[naam][synoniemletter=,tekstletter=,
+%I status=,plaats=,breedte=,criterium=,conversie=,
+%I expansie=]
+%I
+%I Als de status 'stop' is, dan worden geen synoniemen naar
+%I de lijst weggeschreven. Als het criterium 'alles' is,
+%I dan worden alle synoniemen in het overzicht opgenomen, zoniet,
+%I dan worden alleen gebruikte synoniemen opgenomen. Omdat
+%I standaard 'conversie' op 'nee' staat, worden afkortingen
+%I getoond.
+%P
+%I In principe is een synoniem pas beschikbaar als het is
+%I gedefinieerd. Het is echter mogelijk synoniemen te laden,
+%I mits de tekst tenminste eenmaal is verwerkt. Het is dus
+%I mogelijk synoniemen op te roepen die pas later worden
+%I gedefinieerd. Alleen de omschrijvingen zijn beschikbaar,
+%I dus niet de commando's (doordenkertje). Het laden vindt
+%I plaats met:

+%I Als de status 'stop' is, dan worden geen sorteringen naar

+%I Bij koppen daarentegen plaatsen we \index na de kop:
+%I
+%I \subparagraaf{dat is dat}
+%I \index{ziezo}
+%I
+%I ........... tekst .....
+%I
+%I of
+%I
+%I \margewoord{ziezo}
+%I \index{ziezo}
+%I
+%I ........... tekst .....
+%I
+%I Ongewenste spaties na \index worden verwijderd! Wil men
+%I dus een spatie, dan moet dit worden afgedwongen met \ .
+%P
+%I Mocht het hierboven beschreven mechanisme interfereren
+%I met andere mechanismen, dan kan ook het volgende commando
+%I worden gebruikt:
+%I
+%I \schrijfnaarregister[naam][ascii]{ingang+ingang+ingang}
+%I
+%I waarbij [ascii] optioneel is.
+%P
+%I De registers kunnen worden ingesteld met het commando:
+%I
+%I \stelregisterin[naam][letter=,aanduiding=,n=,
+%I balanceren=,uitlijnen=,criterium=,afstand=,symbool=,
+%I expansie=]
+%I
+%I waarbij 'aanduiding' betrekking heeft op het al dan niet
+%I plaatsen van een letter ('ja' of 'nee') en 'letter' op de
+%I weergave van de letter.
+%I
+%I Met 'criterium' kan een subindex worden opgeroepen,
+%I bijvoorbeeld 'deel' of 'hoofdstuk', of als het niveau
+%I onbekend is: 'lokaal'. Standaard wordt een volledige index
+%I gegenereerd ('alles').
+%I
+%I In plaats van een paginanummer kan een symbool worden
+%I gezet: n (1,2,3,..), a (a,b,c,..), 1 (bolletjes) en
+%I 2 (rechthoekjes). Een symbool heeft alleen zin bij
+%I interactieve teksten.
+%I
+%I Voor eigen gebruik is \ifregistergeplaatst beschikbaar.
+%P
+%I In plaats van een + als scheider kan ook & worden
+%I gebruikt. Bovendien kan als eerste karakter worden opgegeven
+%I wat de scheider is:
+%I
+%I \index[abcformule]{&formule&$ax^2+bx+c$}
+%I
+%I Overigens gaat de & voor de +, zodat hier de specificatie
+%I niet per se nodig is. Let wel: dit is een kenmerk van
+%I texutil, en niet zozeer van ConTeXt.
+
+% Formaat tex-utility-input-file <jobname.tui>:
+%
+% i e {tag} {loc} {pure} {entry+..} {p:c:p:sp:ssp=>page} {realpage}
+% i s {tag} {loc} {pure} {entry+..} {other entry}
+%
+% In plaats van + kan een & worden gebruikt. Ook kan als
+% eerste karakter worden opgegeven wat de scheider is.
+%
+% Deze file wordt met het programma TeXUtil omgezet in
+% een in te lezen TeXFile met de commando's:
+%
+% \registerentrya {tag} {ingang}
+% \registerentryb {tag} {subingang}
+% \registerentryc {tag} {subsubingang}
+%
+% \registerpage {tag} {volgnummer} {paginanummer} {volgnummer}

+%I n=Index
+%I c=\index,\zieindex,\volledigeindex
+%I
+%I Een ingang naar de index wordt gecreeerd met:
+%I
+%I \index[ascii]{ingang+ingang+ingang}
+%I
+%I Een verwijzing wordt gecreerd met:
+%I
+%I \zieindex[ascii]{ingang+ingang+ingang}{andere ingang}
+%I
+%I Een index kan (vooralsnog) alleen een eenvoudig
+%I zetcommando afhandelen, bijvoorbeeld: \index{\bf{test}} of
+%I \index{\kap{anwb}}. Meer is vaak niet nodig.
+%I
+%I Als een ingang niet goed gesorteerd wordt, dient [ascii]
+%I te worden meegegeven: \index[anwb]{\kap{anwb}}.
+%I
+%I Een index wordt gegenereerd met:
+%I
+%I \plaatsindex
+%I \volledigeindex
+
+%T n=index
+%T m=ind
+%T a=i
+%T
+%T \index{?}
+
+%I n=Buffers
+%I c=\startbuffer,\haalbuffer,\typebuffer
+%I
+%I Een stuk tekst kan in een buffer worden opgeslagen en
+%I later worden opgeroepen. Dit kan de opbouw van de
+%I ruwe ASCII-file ten goede komen.
+%I
+%I \startbuffer[naam]
+%I \stopbuffer
+%I
+%I Een buffer is eigenlijk een tijdelijke file. Deze file
+%I heeft de extensie 'tmp' en overschrijft dus een file met
+%I dezelfde naam!
+%I
+%I Een buffer kan worden opgeroepen met:
+%I
+%I \haalbuffer[naam]
+%I \typebuffer[naam]
+%I
+%I In alle gevallen is de naam optioneel en mag dus worden
+%I weggelaten.
+%P
+%I Voor en na het wegschrijven kunnen commando's worden
+%I uitgevoerd. Deze worden ingesteld met:
+%I
+%I \stelbufferin[voor=,na=]
+%P
+%I Omdat het argument optioneel is, wat moet worden getest,
+%I worden alle spaties tot het eerste woord onderdrukt. Dit
+%I betekent dat als er moet worden getypt (\typebuffer) en
+%I terwijl voor het eerste woord spaties moeten staan, er
+%I bewust wel (!) een naam moet worden opgegeven.

+%I n=Tekstblokken
+%I c=\definieerblok,\verbergblokken,\handhaafblokken
+%I c=\gebruikblokken,\selecteerblokken,\stelblokin
+%I
+%I Het is mogelijk blokken tekst te verbergen en op andere
+%I plaatsen in de tekst op te roepen. Voorbeelden hiervan
+%I zijn vragen en antwoorden. De antwoorden kunnen onder de
+%I vragen worden ingetypt en bijvoorbeeld in een apart
+%I hoofdstuk worden opgenomen.
+%I
+%I Een tekstblok wordt gedefinieerd met het commando
+%I
+%I \definieerblok[naam]
+%I
+%I en wordt vervolgens steeds omringd door de commando's
+%I
+%I \beginvannaam
+%I tekst
+%I \eindvannaam
+%P
+%I Het zetten van blokken kan worden onderdrukt met het
+%I commando
+%I
+%I \verbergblokken[naam,naam,...]
+%I
+%I wat weer ongedaan gemaakt kan worden met:
+%I
+%I \handhaafblokken[naam,naam,...]
+%I
+%I Blokken kunnen worden opgeroepen met de commando's
+%I
+%I \gebruikblokken[naam,naam,...]
+%I \selecteerblokken[naam,naam,...][criterium=]
+%I
+%I Als criterium kan worden opgegeven: alles of hoofdstuk. In het
+%I laatste geval worden alleen de bij het actulele hoofdstuk horende
+%I blokken tussengevoegd.
+%P
+%I Men moet zonodig eerst het (opnieuw) aanmaken van referenties
+%I onderdrukken met het commando \stelrefererenin[status=stop].
+%I
+%I Genummerde tekstonderdelen (b.v. \doornummeren[vraag]) moeten
+%I desgewenst worden gereset (b.v.\resetvraag)
+%P
+%I De met het volgende commando in te stellen parameters hebben
+%I betrekking op het gebruiken van blokken:
+%I
+%I \stelblokin[naam][voor=,na=,binnen=,letter=]
+%I
+%I Een blok wordt altijd binnen een groep uitgevoerd ({ }).
+%I Zowel 'voor' als 'na' worden buiten deze groep
+%I uitgevoerd, en 'binnen' binnen de groep.
+%P
+%I Soms is het wenselijk tijdens \gebruikblokken sommige blokken
+%I wel 'uit te voeren' maar niet (nogmaals) in de tekst op te
+%I nemen. Als een blok wordt definieerd met:
+%I
+%I \beginvannaam[-]
+%I tekst
+%I \eindvannaam
+%I
+%I dan wordt het ter plaatse al dan niet gezet en bij het later
+%I oproepen wel verwerkt maar niet gezet.
+%I
+%I Als in de tekst een blok wel moet worden verwerkt, maar niet
+%I gezet, dan kan [+] worden opgegeven.
+%P
+%I Het handhaven, verbergen en gebruiken van blokken kan door
+%I de hele tekst plaatsvinden. Binnen ieder hoofdstuk kunnen
+%I bijvoorbeeld blokken worden gedefinieerd die aan het eind van
+%I het hoofdstuk worden opgeroepen. Dit mechanisme noodzaakt
+%I tenminste twee maal verwerken van de file met TeX.
+%I
+%I Een tweede pass is echter niet nodig als na het gebruik geen
+%I nieuwe blokken meer worden gedefinieerd. In dat geval kan
+%I vlak voordat de blokken worden opgeroepen, het commando
+%I
+%I \geenblokkenmeer
+%I
+%I worden gegeven. Dit scheelt tijd.
+
+% In eerste instantie is gebruik gemaakt van een utilityfile. Dit
+% is echter niet perse noodzakelijk. Wellicht dat als er blokken
+% moeten worden gesorteerd, toch weer texutil moet worden
+% gebruikt.
+
+% In de block-move variant hieronder wordt gebruik gemaakt van
+% de in de \answer-macro van Knuth gebruikte copieermethode.
+% Blokken kunnen worden
+%
+% \gehandhaafd : in de tekst worden opgenomen �n gecopieerd
+% \verborgen : alleen worden gecopieerd
+% \gebruikt : later in de tekst worden opgenomen
+% \geselecteerd : later selectief in de tekst worden opgenomen
+%
+% Ieder blok wordt gecopieerd naar de file 'jobname.tmp'.
+% Daarnaast wordt een blok tijdelijk opgeslagen in de file
+% 'texutil.tmp'. Handhaven kom tneer op het opnieuw inlezen van
+% deze file.
+%
+% De file 'jobname.tmp' wordt later gecopieerd naar de file
+% 'jobname.tum'. Dit is nodig om in een eerdere run verzamelde
+% blokken te kunnen verwerken.
+
+% Werken met \copie gaat fout. Bovendien zijn de spaties
+% belangrijk!
+%
+% \def\c!copie{copie} % vervalt, verkeerde catcodes
+
+% The use of \string prevents spaces kreeping in when
+% converting the string. Although we can use \meaning in a
+% more direct way, we prfer to use \convertargument, because
+% this way the macro's are more readible.

+%I [boven,hoofd,tekst,voet,onder]
+%I [linkerrand,rechterrand,linkermarge,reachtermarge,tekst]
+%I [achtergrond=,kleur=,raster=]

+%I Voor de hele bladzijde gebruiken we:

+%P
+%I Het is mogelijk elk blok iets ruimer om de tekst te

+%I [pagina]
+%I [offset=,diepte=]
+%I
+%I Een offset van .25\korpsgrootte en een diepte van
+%I .5\korpsgrootte voldoen aardig.
+%I
+%I Er kunnen ronde hoeken worden gezet met:
+%I
+%I \stelachtergrondenin

+%I c=\startomgeving,\startdeelomgeving
+%I
+%I Een eenvoudige tekst wordt gestart en gestopt met de
+%I commando's:
+%I
+%I \starttekst
+%I \stoptekst
+%P
+%I Het is mogelijk een projektstructuur op te zetten. Per
+%I projekt wordt een file aangemaakt waarin de volgende
+%I commando's voorkomen:
+%I
+%I \startprojekt naam
+%I \stopprojekt
+%I
+%I Als deze file in TeX wordt geladen, dan worden alle
+%I produkten achter elkaar gezet.
+%I
+%I Een produkt wordt gedefinieerd met:
+%I
+%I \startprodukt naam
+%I \stopprodukt
+%I
+%I Deze file kan zelfstandig door TeX worden gehaald.
+%P
+%I Een omgeving wordt gedefinieerd door:
+%I
+%I \startomgeving naam
+%I \stopomgeving
+%I
+%I Een onderdeel wordt gedefinieerd door:
+%I
+%I \startonderdeel naam
+%I \stoponderdeel
+%I
+%I Files worden eerst gezocht op het actuele gebied. Als een
+%I file niet aanwezig is wordt op de 'roots' gezocht.
+%I
+%I Een onderdeel kan zelfstandig door TeX worden gehaald.
+%P
+%I Binnen een projekt, produkt, omgeving of onderdeel komen
+%I de volgende instellingen voor (tussen haakjes=facultatief):
+%I
+%I projekt omgeving produkt onderdeel
+%I
+%I \projekt naam * *
+%I \omgeving naam (*) (*) (*) (*)
+%I \produkt naam *
+%I \onderdeel naam (*) (*)
+%I
+%I Binnen een omgeving kunnen deelomgevingen worden gedefinieerd
+%I die alleen voor bepaalde produkten, onderdelen enz. gelden.
+%I
+%I \startdeelomgeving[naam,...,naam]
+%I commando's
+%I \stopdeelomgeving
+%P
+%I Het programma TeXEdit doorzoekt bij het aanmaken van een
+%I file-menu de hele tekst op de genoemde commando's. Bij een
+%I lange tekst kan dit misschien 'te' lang duren. Met het
+%I commando:
+%I
+%I \geenfilesmeer
+%I
+%I kan worden aangegeven dat er geen structuurcommando's meer
+%I volgen.
+%I
+%I Ten behoeve van TeXUtil moet in plaats van het commando
+%I \input het commando \verwerkfile{naam} worden gebruikt.
+%P
+%I Als men standaard een en ander wil instellen, dan kan men
+%I dit doen in de file 'cont-sys.tex'. Deze file wordt direkt
+%I na het opstarten geladen cq. uitgevoerd. Daarnaast wordt,
+%I indien aanwezig, de file 'cont-new.tex' geladen.

+%I Het is mogelijk eigen commando's te definieren met behulp

+%I \definieer[aantal argumenten]\commando{betekenis}
+%I
+%I Een argument kan worden opgeroepen door een # gevolgd

+%I \naam{}
+%I
+%I In een aantal gevallen, bijvoorbeeld bij het wegschrijven

+%I n=Items
+%I c=\items,\stelitemsin
+%I
+%I Met het commando \items kunnen invullijsten worden
+%I gegenereerd:
+%I
+%I \items{alternatief1,alternatief2,...,alternatiefN}
+%I
+%I Als in plaats van een alternatief een - wordt gegeven,
+%I dan wordt ruimte opengelaten.
+%I
+%I De wijze waarop items worden weergegeven wordt ingesteld
+%I met het commando:
+%I
+%I \stelitemsin[plaats=,symbool=,breedte=,n=,voor=,
+%I tussen=,na=,uitlijnen=]
+%I
+%I Mogelijke plaatsen zijn links, rechts, onder, boven en
+%I inmarge. Als breedte wordt de breedte van de totale tekst
+%I opgegeven. Het aantal is facultatief, eventueel kan er
+%I 'onbekend' worden meegegeven. Uitlijnen is 'ja' of 'nee'.
+%P
+%I Indien gewenst, kan de instelling direkt achter \item worden
+%I geplaatst:
+%I
+%I \items[plaats=,symbool=,...]{alternatief1,...}
+%I
+%I In plaats van een symbool kan ook een van de volgende
+%I aanduidingen worden meegegeven:
+%I
+%I a a, b, c, d, ...
+%I A A, B, C, D, ...
+%I n 1, 2, 3, 4, ...
+%I r i, ii, iii, ...
+%I R I, II, III, ...
+%I
+%I Eventueel kan een nummer worden meegegeven. In dat
+%I geval wordt het overeenkomstige symbool van de
+%I opsomming gebruikt (1--n).

+% Een verdere 'besparing' kan worden gerealiseerd als de
+% variabelen (ef#1...) lokaal blijven als een figuur wordt
+% geladen. Ook kunnen in texutil.tuf \c!variabelen worden
+% gebruikt.
+
+%I n=Figuren+
+%I c=\gebruikexternfiguur,\gebruikexternefiguren,\externfiguur
+%I c=\figuurintekst
+%I
+%I Extern aangemaakte (postscript)-figuren kunnen in
+%I de tekst worden opgenomen. De afmetingen van deze
+%I figuren kunnen op verschillende manieren worden
+%I ingesteld:
+%I
+%I \gebruikexternfiguur[naam][file][schaal=,kader=]
+%I
+%I \gebruikexternfiguur[naam][file][hfactor=,kader=]
+%I \gebruikexternfiguur[naam][file][bfactor=,kader=]
+%I
+%I \gebruikexternfiguur[naam][file][hoogte=,kader=]
+%I \gebruikexternfiguur[naam][file][breedte=,kader=]
+%I
+%I \gebruikexternfiguur[eerste naam][file][....]
+%I \gebruikexternfiguur[tweede naam][file][eerste naam]
+%I
+%I Externe figuren kunnen vervolgens worden opgeroepen op
+%I naam:
+%I
+%I \naam
+%P
+%I De schaal wordt opgegeven in tienden procenten. Dat
+%I betekent dat 12.5 procent wordt opgegeven als 125.
+%I
+%I In plaats van een schaal kan ook een schaalfactor worden
+%I opgegeven. Een factor 15 resulteert in een figuur met een
+%I hoogte van 1.5 maal de korpsgrootte. In plaats van een
+%I getal kan ook 'max', 'passend' of 'ruim' worden opgegeven.
+%I
+%I De breedte en hoogte worden opgegeven in de gebruikelijke
+%I TeX-maten.
+%I
+%I Als men automatisch wil laten bepalen wat de maximale
+%I hoogte of breedte is, dan kan men 'factor=max' meegeven.
+%P
+%I Externe figuren moeten worden voorgedefinieerd. Dit doet
+%I men met het commando:
+%I
+%I \presetfigure[file][type=,breedte=,hoogte=,
+%I omvang=,bron=,titel=]
+%I
+%I Met behulp van texutil kan een file 'texutil.tuf'
+%I worden aangemaakt waarin de op het werkgebied beschikbare
+%I figuren worden voorgedefinieerd. In dat geval kan het
+%I commando \presetfigure achterwege blijven.
+%I
+%I De voorinstellingen worden geladen met het commando:
+%I
+%I \gebruikexternefiguren[optie=,korps=,lokatie=]
+%I
+%I waarbij als opties kader en leeg mogelijk zijn. In
+%I het eerste geval wordt een kader om de figuren
+%I geplaatst, in het tweede geval worden alleen kenmerken
+%I van de figuur weergegeven. Lokatie kan lokaal, globaal
+%I of {lokaal,globaal} (default) zijn.
+%P
+%I Figuren kunnen op het actuele gebied staan, op een root
+%I van het actuele gebied of op een nader in te stellen gebied.
+%I Dit instellen gebeurt door aan 'gebied' een naam toe te
+%I kennen.
+%I
+%I De in de file 'system.tex' opgenomen standaardinstelling
+%I is (let op het gebruik van /):
+%I
+%I \stelexternefigurenin[gebied=c:/figuren/eps,file=]
+%P
+%I Het eerder genoemde commando \gebruikexternfiguur ziet
+%I er als volgt uit:
+%I
+%I \gebruikexternfiguur[naam][file][instellingen]
+%I
+%I De naam is facultatief en is standaard gelijk aan de
+%I filenaam. Als een (file)naam cijfers bevat, moet het
+%I commando \naam{naam} worden gebruikt.
+%I
+%I Het is mogelijk in \plaatsfiguur direkt een externe
+%I figuur op te roepen:
+%I
+%I \plaatsfiguur{commentaar}{\naam}
+%I
+%I Ook is het mogelijk een figuur in de tekst op te nemen
+%I met het commando:
+%I
+%I \figuurintekst{\naam}
+
+%T n=extern
+%T m=ext
+%T a=e
+%T
+%T \gebruikexternfiguur [] [?] [bfactor=]
+
+%D The following macro's are derived from Thomas Rockicky's
+%D macro's. They are rewritten to a more compact form, made a
+%D bit more robust and also handle the \type{HiResBoundingBox}
+%D or \type{ExactBoundingBox} that sometimes is present.
+%D
+%D A bounding box has the form:
+%D
+%D \starttypen
+%D %%BoundingBox: llx lly urx ury
+%D \stoptypen
+%D
+%D Before we scan the file, we have to reset special
+%D characters and set some others. The percentage symbol also
+%D needs special treatment. When a bounding box is
+%D encountered, we keep on scanning until no more directives are
+%D found, i.e. a line is found that does not start with a
+%D percentage symbol. We also abort scanning after finding a
+%D high resolution bounding box.
+%D
+%D This method also works inside verbatim mode (like when we
+%D are typesettinmg sources and putting eps coded logos into
+%D a heading. Temporary restoring the \CATCODES\ is done in
+%D the calling routine.

+%I n=Combinaties
+%I c=\startcombinatie,\stelcombinatiesin
+%I
+%I Er kunnen meerdere tabellen, figuren enz. worden
+%I gecombineerd. Dit gebeurt met het commando:
+%I
+%I \startcombinatie[n*m]
+%I {inhoud 1}{ondertitel 1}
+%I {inhoud 2}{ondertitel 2}
+%I .....
+%I \stopcombinatie
+%I
+%I Eventueel kan volstaan worden met [n]. Vier inhouden
+%I kunnen bijvoorbeeld worden gecombineerd als:
+%I
+%I [4*1] of [4] vier inhouden naast elkaar
+%I [1*4] vier inhouden onder elkaar
+%I [2*2] inhouden twee aan twee onder elkaar
+%P
+%I Dit commando is goed te combineren met \plaats-commando's:
+%I
+%I \plaatsfiguur[][]{}
+%I \startcombinatie[2]
+%I {\legefiguur}{a}
+%I {\legefiguur}{b}
+%I \stopcombinatie
+%I
+%I Rond \start-\stopcombineer hoeven geen {} te worden
+%I geplaatst.
+%I
+%I De afstanden tussen de inhouden en de titels kunnen worden
+%I ingesteld met:
+%I
+%I \stelcombinatiesin[voor=,na=,tussen=,afstand=,
+%I uitlijnen=,hoogte=,breedte=]
+%I
+%I Waarbij de afstand betrekking heeft op de horizontale
+%I afstand (een maat dus) en voor, na en tussen commando's
+%I zijn (bijvoorbeeld \blanko).

+%I
+%I Waarbij als rotatie 0, 90, 180 of 270 kan worden opgegeven.
+%I Als extra instellingen kunnen de instellingen van
+%I \omlijnd worden meegegeven. Er wordt gebruik gemaakt van
+%I het \special commando en het rotatiemechanisme van
+%I PostScript. Dit betekent dat in de previewer de tekst
+%I niet (!) geroteerd wordt. Overigens draagt TeX zorg voor
+%I de exacte plaatsing, uitlijnen enz. De afhankelijkheid
+%I van PostScript is dus tot een minimum beperkt.
+%I
+%I Verder zijn dezelfde instellingen mogelijk als bij
+%I \omlijnd.

+%I c=\definieerinteractiemenu,\startinteractiemenu
+%I c=\blokkeerinteractiemenu,\geefinteractiemenuvrij
+%I c=\stelinteractieschermin,\scherm
+%I
+%I Overzichten en verwijzingen kunnen worden voorzien van
+%I voor DVIWINDO en Acrobat betekenisvolle codes. De volgende
+%I commando's zijn (voorlopig) beschikbaar:
+%I
+%I \stelinteractiein[status=,menu=,letter=,kleur=,strut=,
+%I breedte=,hoogte=,diepte=,pagina=]
+%I
+%I Hierbij hebben 'letter' en 'kleur' betrekking op in de tekst
+%I gemarkeerde woorden waar een verwijzing achter zit. Status
+%I kan 'start' of 'stop' zijn en het 'menu' kan 'aan' of 'uit'
+%I staan. Met 'pagina=ja' dwingen we pagina verwijzingen af.
+%I
+%I Zonodig kunnen een 'titel', 'subtitel', 'auteur' en 'datum'
+%I worden ingesteld.
+%P
+%I Een menu wordt gedefinieerd met het commando:
+%I
+%I \definieerinteractiemenu[naam][plaats][instellingen]
+%I
+%I waarbij in plaats van de instellingen de naam van een
+%I reeds gedefinieerd menu kan worden opgegeven.
+%I
+%I Mogelijke plaatsen zijn 'boven', 'onder', 'links' en
+%I 'rechts'.
+%P
+%I De inhoud van een menu wordt gedefinieerd met:
+%I
+%I \definieerinteractiemenu[naam][inhoud]
+%I
+%I Een voorbeeld van zo'n definitie is:
+%I
+%I \definieerinteractiemenu
+%I [links]
+%I [{inhoud[inhoud]},
+%I {formules[formules]},
+%I {index[index]}]
+%I
+%I De accolades zijn essentieel! De verwijzingen dienen met de
+%I daarvoor gebruikelijke commando's te worden aangemaakt.
+%I Verwijzingen zoals [inhoud] en [index] zijn automatisch
+%I beschikbaar.
+%P
+%I Naast [inhoud], [index] en andere voor de hand liggende
+%I verwijzingen zijn beschikbaar:
+%I
+%I [eerstepagina]
+%I [vorigepagina]
+%I [volgendepagina]
+%I [laatstepagina]
+%P
+%I Een alternatieve manier om menu's te definieren levert
+%I het commando
+%I
+%I \startinteractiemenu
+%I \stopinteractiemenu
+%I
+%I Hierbinnen zijn de volgende commando's mogelijk:
+%I
+%I \raw tekst \\ : ongeformatteerde tekst
+%I \but[ref] tekst \\ : interactief menu item
+%I \nop \\ : dummy menu item
+%I \txt tekst \\ : niet interactief menu item (omlijnd)
+%I \rul tekst \\ : niet interactief menu item
+%I \com commandos \\ : commando's
+%P
+%I Instellingen kunnen ook apart plaatsvinden met:
+%I
+%I \stelinteractiemenuin[naam][voor=,na=,tussen=,breedte=,
+%I kader=,letter=,status=,achtergrond=,achtergrondkleur=,
+%I achtergrondraster=]
+%I
+%I Aan 'voor', 'na' en 'tussen' kunnen commando's worden
+%I toegekend, zoals: \hfill, \blanko en \hskip1em. Bij
+%I 'breedte' kan een maat, 'passend' of 'ruim' worden
+%I meegegeven. Het kader kan 'aan' of 'uit' staan.
+%I
+%I De status kan 'start', 'stop', 'leeg' of 'geen' zijn. De
+%I instelling 'leeg' geldt slechts een pagina. De instelling
+%I 'geen' heeft alleen zin bij meerdere menus naast cq. boven
+%I elkaar.
+%P
+%I Het is mogelijk een menu te (de)blokkeren. Dit gebeurt met
+%I behulp van het referentie-mechanisme. Het commando luidt:
+%I
+%I \blokkeerinteractiemenu[plaats][verwijzingen]
+%I \geefinteractiemenuvrij[plaats][verwijzingen]
+%I
+%I De verwijzingen moeten worden gescheiden door comma's.
+%I Wanneer geen verwijzingen worden meegegeven, wordt de
+%I blokkade opgeheven.
+%P
+%I Eventueel kunnen tussen menuitems commando's worden
+%I opgenomen,
+%I
+%I \definieerinteractiemenu
+%I [links]
+%I [{alfa[eerste]},
+%I {beta[tweede]},
+%I {{\blanko[forceer,3*groot]}},
+%I {gamma[derde]},
+%I {{\vfil}},
+%I {omega[laatste]}]
+%I
+%I De extra {} zijn nodig, omdat anders onduidelijkheid is
+%I of het commando's zijn of verwijzingen.
+%P
+%I De afmetingen van het interactiescherm kunnen worden
+%I ingesteld met het commando:
+%I
+%I \stelinteractieschermin[breedte=,hoogte=,rugwit=,
+%I kopwit=,optie=]
+%I
+%I Dit is alleen nodig als men het interactieprogramma wil
+%I dwingen de tekst op een afwijkend papierformaat weer te
+%I geven. Als hoogte en breedte kan 'passend' worden
+%I opgegeven, in dat geval wordt uitgegaan van de
+%I instellingen bij \stellayoutin.
+%I
+%I Er kan (in acrobat) met een vol scherm worden opgestart
+%I met optie=max.
+%P
+%I Er zijn meerdere menu's naast elkaar mogelijk. Eerst
+%I wordt een menu gedefinieerd met:
+%I
+%I \definieerinteractiemenu[naam][plaats][instellingen]
+%I
+%I De afstand tussen menus wordt ingesteld met 'afstand'.
+%I Als afstand=overlay dan vallen menus over elkaar.

+%D Due to requests I finally decided to support bookmarks, a
+%D driver dependant way of showing tables of content. The most
+%D simple way of support is hooking bookmark generation into
+%D the existing list mechanisms. That way users can generate
+%D bookmarks automatically, although its entirely valid to add
+%D bookmarks by defining alternative ones. These will be added
+%D at the appropriate place in the list.

+%I Het is mogelijk naar een plaats in een figuur te verwijzen.

+%I ...
+%I \markeer(xn,yn)(hn,bn)[referentien]%
+%I ...
+%I \stopfiguur
+%P
+%I Wanneer als optie bij \gebruikexternefiguren 'test' wordt
+%I meegegegeven, wordt een testpagina met een rasterverdeling
+%I gegenereerd. Met x en y wordt de linkerbovenhoek ingesteld,
+%I met h en b de hoogte en de breedte van het te markeren deel
+%I van de figuur.
+%I
+%I Standaard is de hoogte verdeeld in 24 stukken. Wil men een
+%I andere indeling, dan kan men met \gebruikexternefiguren
+%I de 'xmax' of 'ymax' instellen (aanbevolen: 10 - 50).
+%I
+%I De hokjes waarop geklikt kan worden kunnen zichtbaar worden
+%I gemaakt met 'hokjes=aan'.
+%P
+%I Om duidelijk te kunnen maken achter welke delen van een
+%I figuur iets zit, kan een kleurenbalk worden opgenomen.
+%I
+%I ...
+%I \kleurenbalk[...,...,...]
+%I ...
+%I
+%I (deze tekst moet nog worden aangevuld)
+%P
+%I Het is mogelijk in een tekst toelichtingen op te nemen.
+%I
+%I ...
+%I \toelichting(x1,y1)(h1,b1)[instellingen]{tekst}
+%I ...
+%I
+%I De instellingen zijn optioneel en komen overeen met die van

+%I c=\stelsynchronisatiein,\stelsynchronisatiebalkin,\synchronisatiebalk
+%I
+%I Mits ondersteund door het interactieprogramma, kan naar
+%I een andere file worden gesprongen. Zo'n file moet eerst
+%I worden gedefinieerd met:
+%I
+%I \gebruikexterndocument [naam] [file] [omschrijving]
+%I
+%I Een verwijzing naar een andere file ziet er als volgt
+%I uit:
+%I
+%I \in{tekst}[naam::verwijzing]
+%I \op{tekst}[naam::verwijzing]
+%I \naar{tekst}[naam::verwijzing]
+%I
+%I De naam van het andere document kan worden opgeroepen met
+%I
+%I \uit[naam]
+%I
+%I terwijl \uit zonder [naam] de bij \in, \op of \naar
+%I behorende omschrijving oproept.
+%P
+%I Documenten kunnen worden gesynchroniseerd. Dat wil zeggen
+%I dat gesprongen kan worden naar hetzelfde punt in een anders
+%I vormgegeven tekst. Een synchronisatiepunt wordt aangegeven
+%I met:
+%I
+%I \sychroniseer
+%I
+%I Een synchronisatie kan uit de pas lopen, bijvoorbeeld als
+%I we in een kop een synchronisatiebalk oproepen. Wanneer vindt
+%I immers precies de synchronisatie plaats? Vandaar de wat
+%I meer betrouwbare menier van aangeven:
+%I
+%I \startsynchronisatie % voor de kop (nu mag balk)
+%I \stopsynchronisatie % eind van de kop (fixeert plaats)
+%P
+%I Synchronisatie kan worden ingesteld met:
+%I
+%I \stelsynchronisatiein[status=]
+%I
+%I Het synchronisatiemechanisme is in geval van interactieve
+%I teksten standaard niet actief.
+%P
+%I Er kan een synchronisatiebalk worden opgeroepen waarmee
+%I naar een ander document kan worden gesprongen.
+%I
+%I \synchronisatiebalk[naam][instellingen]
+%I
+%I De instellingen kunnen ook apart worden opgegeven:
+%I
+%I \stelsynchronisatiebalkin[variant=,breedte=,
+%I letter=,kleur=,achtergrond=,achtergrondraster=,
+%I achtergrondkleur=]
+%I
+%I Mogelijke varianten zijn 'lokaal' en 'pagina'. In het
+%I eerste geval wordt slechts een mogelijkheid geboden, in het
+%I tweede geval zijn tot drie mogelijkheden mogelijk. Deze
+%I zijn te vergelijken met markeringen.
+
+% De commando's \setreference en \gotolocation zijn reeds
+% gedefinieerd in pragma1.tex. De aanpassing hieronder heeft

+%I n=Interactiebalk
+%I c=\interactiebalk,\stelinteractiebalkin
+%I
+%I Het volgende commando genereert een interactiebalk. Pas op:
+%I de waarde van \realpageno staat niet echt vast.
+%I
+%I \interactiebalk[variant=,breedte=,hoogte=,diepte=,
+%I achtergrond=,achtergrondkleur=,achtergrondraster=,
+%I kader=,stap=]
+%I
+%I \interactiebalk[reset]
+%I
+%I \stelinteractiebalkin[...]
+%I
+%I Mogelijke stappen zijn 'klein', 'middel', 'groot' en 'n';
+%I beschikbare varianten zijn:
+%I
+%I a meter (scrollbar)
+%I b jumper (symbool: begin terug vooruit eind)
+%I c jumper (balk: begin terug vooruit eind)
+%I d pagina (subpaginas vast formaat)
+%I e pagina (subpaginas vrij formaat)
+%I f pagina (subpaginas grote aantallen)
+%I g pagina (subpaginas jumper)
+
+% Dit is leuke toepassing van glue!

+%I
+%I Er kunnen een gericht leesprofiel worden gedefinieerd.
+%I Daartoe worden delen van de tekst gemerkt met commando:
+%I
+%I \startprofiel[label,label,...]

+%I n=Versies
+%I c=\definieerversie,\stelversiesin,\startversie
+%I c=\selecteerversie,\markeerversie,\volgversie
+%I
+%I Het mechanisme om wijzigingen in een tekst te markeren en
+%I selecteren sluit aan op dat van profielen.
+%I
+%I Een deel van de tekst kan worden gemarkeerd met ofwel
+%I
+%I \startversie[nr,nr,...]
+%I \stopversie
+%I
+%I of tussen @+ ...... @-. Eventueel mogen achter @+ nummers
+%I worden opgenomen: @+nr,nr,... ...... @-.
+%I
+%I Aldus gemerkte tekst kan in een afwijkende letter worden
+%I weergegeven, bijvoorbeeld \ss. Daarbij wordt de laagste
+%I nog te mrkeren versie opgegeven:
+%I
+%I \stelversiesin[nummer=,letter=]
+%I
+%I Een versienummer mag punten (.) bevatten. Deze worden
+%I voor het vergelijken niet meegenomen. Oppassen dus: 1.10
+%I wordt 110 en 2.2 wordt 22 en moet dus 2.02 zijn.
+%P
+%I Het is mogelijk alleen de 'recente' wijzigingen te
+%I verwerken. Dit gaat in twee slagen:
+%I
+%I \markeerversie (eerste slag)
+%I \selecteerversie (tweede slag)
+%I
+%I Er is gekozen voor het bewust markeren, omdat het
+%I markeren gaat ten koste van de omvang van de hulpfile.
+%P
+%I Evenals profielen, kunnen ook versie worden gevolgd. Ook
+%I hier dient eerst een definitie plaats te vinden:
+%I
+%I \definieerversie[naam][nummer,nummer,nummer]
+%I
+%I waarna gebruik kan worden gemaakt van:
+%I
+%I \volgversie{tekst}[naam]
+%I
+%I Er is ook een combinatie (doorsnede) mogelijk van
+%I profielen en versies:
+%I
+%I \volgprofielversie{tekst}[naam profiel][naam versie]

+%I n=Kontakten
+%I c=\laadkontakten
+%I
+%I De onderstaande commando's werken samen met het programma
+%I TeXAdres.
+%I
+%I \laadkontakten[naam,groep,...]
+%I
+%I Dit commando doorzoekt eerst de file 'texadres.tao' en
+%I vervolgens de file 'texadres.tae' op naam en groep. Bij
+%I elk gevonden adres (naam of groepslid) wordt het commando
+%I \doemetkontakt{logisch} aangeroepen.
+%I
+%I De waarden van de verschillende velden zijn op te roepen met
+%I het commando \kontaktwaarde{veldnaam}. Let op: het in
+%I bijvoorbeeld een adres opgenomen commando \\ moet men zelf
+%I definieren, bijvoorbeeld: \def\\{\endgraf}.
+%P
+%I TeXAdres zet alle files op een gebied met de extensie 'tai'
+%I om in een file met de extensie 'tao' of 'tae'. Een invoerfile
+%I is als volgt opgebouwd:
+%I
+%I Een adres in de uitvoerfile ziet er als volgt uit:
+%I
+%I \beginvankontakt{...}
+%I \lidvangroep{...,...,...}
+%I \naam{...}
+%I \letters{...}
+%I \...{...}
+%I \postadres{...}
+%I \eindvankontakt{...}
+%P
+%I De invoerfile bevat zowel definities van kontakten als van
+%I groepen.

+%D This module deals with all kind of conversions from numbers
+%D and dates. I considered splitting this module in a support
+%D one and a core one, but to keep things simple as well as
+%D preserve the overview, I decided against splitting.
+
+%D \macros
+%D {numbers}
+%D
+%D First we deal with the dummy conversion of numbers using the
+%D \TEX\ primitive \type{\number}. The uppercase alternative is
+%D only there for compatibility with the other conversion
+%D macros. We could do without \type{#1} but this way we get
+%D rid of unwanted braces. For the savety we also define a
+%D non||sence uppercase alternative.
+%D
+%D \showsetup{\y!numbers}
+
+\def\numbers#1%
+ {\number#1}
+
+\def\Numbers#1%
+ {\number#1}
+
+%D \macros
+%D {romannumerals,Romannumerals}
+%D
+%D \TEX\ the program uses a rather tricky conversion from
+%D numbers to their roman counterparts. This conversion could
+%D of course be programmed in \TEX\ itself, but I guess Knuth
+%D found the programming trick worth presenting.
+%D
+%D \showsetup{\y!romannumerals}
+%D \showsetup{\y!Romannumerals}
+%D
+%D When upcasing the result, we just follow the text book rules
+%D of expansion. Later on we'll see some more uppercase tricks.
+
+\def\romannumerals#1%
+ {\romannumeral#1}
+
+\def\Romannumerals#1%
+ {\uppercase\expandafter{\romannumeral#1}}
+
+%D \macros
+%D {character,Character}
+%D
+%D Converting a number into a character can of course only
+%D be done with numbers less or equal to~26. At the cost of
+%D much more macros a faster conversion is possible, using:
+%D
+%D \starttypen
+%D \setvalue{char1}{a} \def\character#1{\getvalue{char#1}}
+%D \stoptypen
+%D
+%D But we prefer a simpel \type{\case}.
+%D
+%D \showsetup{\y!character}
+%D \showsetup{\y!Character}
+
+\def\character#1%
+ {\ifcase#1%
+ \or a\or b\or c\or d\or e\or f\or g\or h\or i\or j\or k\or l\or m%
+ \or n\or o\or p\or q\or r\or s\or t\or u\or v\or w\or x\or y\or z%
+ \else
+ #1%
+ \fi}
+
+\def\Character#1%
+ {\ifcase#1%
+ \or A\or B\or C\or D\or E\or F\or G\or H\or I\or J\or K\or L\or M%
+ \or N\or O\or P\or Q\or R\or S\or T\or U\or V\or W\or X\or Y\or Z%
+ \else
+ #1%
+ \fi}
+
+%D \macros
+%D {characters,Characters}
+%D
+%D Converting large numbers is supported by the next two
+%D macros. This time we just count on: $\cdots$~x, y, z, aa,
+%D ab, ac~$\cdots$.
+%D
+%D \showsetup{\y!characters}
+%D \showsetup{\y!Characters}
+
+\def\doconvertcharacters#1#2%
+ {\bgroup
+ \ifnum#2>26
+ \!!counta=#2
+ \ifnum\!!counta>0
+ \advance\!!counta by -1
+ \!!countb=\!!counta
+ \divide\!!counta by 26
+ \!!countc=\!!counta
+ \multiply\!!countc by 26
+ \advance\!!countb by -\!!countc
+ \doconvertcharacters#1{\!!counta}%
+ \advance\!!countb by 1
+ #1{\the\!!countb}%
+ \fi
+ \else
+ #1{#2}%
+ \fi
+ \egroup}
+
+\def\characters%
+ {\doconvertcharacters\character}
+
+\def\Characters%
+ {\doconvertcharacters\Character}
+
+%D \macros
+%D {protectconversion}
+%D
+%D The previous two commands are not robust enough to be
+%D passed to \type{\write} en \type{\message}. That's why we
+%D introduce:
+
+\def\protectconversion%
+ {\def\doconvertcharacters{}}
+
+%D \macros
+%D {normaltime,normalyear,normalmonth,normalday}
+%D
+%D The last part of this module is dedicated to converting
+%D dates. Because we want to use as meaningful commands as
+%D possible, and because \TEX\ already uses up some of those,
+%D we save the original meanings.
+
+\let\normaltime = \time
+\let\normalyear = \year
+\let\normalmonth = \month
+\let\normalday = \day
+
+%D \macros
+%D {month,MONTH}
+%D
+%D Converting the month number into a month name is done
+%D using a case statement, abstact values and the label
+%D mechanism. This way users can easily redefine a label from
+%D for instance german into austrian.
+%D
+%D \starttypen
+%D \setuplabeltext [de] [january=J\"anner]
+%D \stoptypen
+%D
+%D Anyhow, the conversion looks like:
+
+\def\doconvertmonth#1%
+ {\labeltext
+ {\ifcase#1%
+ \or \v!january \or \v!february \or \v!march \or \v!april
+ \or \v!may \or \v!june \or \v!july \or \v!august
+ \or \v!september \or \v!october \or \v!november \or \v!december
+ \fi}}
+
+%D We redefine the \TEX\ primitive \type{\month} as:
+%D
+%D \showsetup{\y!month}
+%D \showsetup{\y!MONTH}
+
+\def\month%
+ {\doconvertmonth}
+
+\def\MONTH#1%
+ {{\let\labeltext=\LABELTEXT\month{#1}}}
+
+%D We never explicitly needed this, but Tobias Burnus pointed
+%D out that it would be handy to convert to the day of the
+%D week. In doing so, we have to calculate the total number of
+%D days, taking leapyears into account. For those who are
+%D curious:
+%D
+%D \startopsomming[opelkaar]
+%D \som years that can be divided by 4 are leapyears
+%D \som exept years that can be divided by 100
+%D \som unless years can be divided by 400
+%D \stopopsomming
+%D
+%D This makes the year 1900 into a normal year and 1996 and
+%D 2000 into leap years, right? Well, converting to string
+%D looks familiar:
+
+\def\doconvertday#1%
+ {\labeltext
+ {\ifcase#1
+ \or \v!sunday \or \v!monday \or \v!tuesday \or \v!wednesday
+ \or \v!thursday \or \v!friday \or \v!saturday \fi}}
+
+%D \macros
+%D {dayoftheweek}
+%D
+%D The conversion algoritm is an old one and a translation from
+%D a procedure written in MODULA~2 back in the 80's. I finaly
+%D found the 4--100-400 rules in some enclopedia. Look at this
+%D messy low level routine that takes the day, month and year
+%D as arguments:
+
+\def\dayoftheweek#1#2#3%
+ {\bgroup
+ \!!counta=\ifcase#2\relax

+%D \macros
+%D {currentdate}
+%D
+%D We use these conversion macros in the date formatting
+%D macro:
+%D
+%D \showsetup{\y!currentdate}
+%D
+%D This macro takes care of proper spacing and delivers for
+%D instance:
+%D
+%D \startbuffer
+%D \currentdate[weekdag,dag,maand,jaar] % still dutch example
+%D \currentdate[WEEKDAG,dag,MAAND,jaar] % still dutch example
+%D \stopbuffer
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D depending of course on the keywords. Here we gave:
+%D
+%D \typebuffer
+%D
+%D If needed one can also add non||keywords, like in
+%D
+%D \startbuffer
+%D \currentdate[dd,--,mm,--,yy]
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D or typeset: \haalbuffer.
+%D
+%D When no argument is passed, the current date is given as

+%D \macros
+%D {definesymbol, symbol}
+%D
+%D Converting numbers or levels into a character, romannumeral,
+%D symbol or something else, is supported by many \CONTEXT\
+%D commands. Therefore we need a mechanism for linking such
+%D numbers to their counterparts.
+%D
+%D First we take care of symbols. These are for instance used
+%D in enumerations and itemizations. We have:
+%D
+%D \showsetup{\y!definesymbol}
+%D \showsetup{\y!symbol}
+%D
+%D Symbols are symply linked to a tag. Such tags can be numbers
+%D or strings.
+%D
+%D \starttypen
+%D \definesymbol [1] [$\bullet$]
+%D \definesymbol [level 5] [$\star$]
+%D \stoptypen
+
+\def\dodefinesymbol[#1][#2]%
+ {\setvalue{\??ss#1}{#2}}%
+
+\def\definesymbol%
+ {\dodoubleargument\dodefinesymbol}
+
+\def\symbol[#1]%
+ {\doifdefinedelse{\??ss#1}{\getvalue{\??ss#1}}{#1}}
+
+%D \macros
+%D {defineconversion, convertnumber}
+%D
+%D Conversion involves the macros that we implemented earlier
+%D in this module.
+%D
+%D \showsetup{\y!defineconversion}
+%D \showsetup{\y!convertnumber}
+%D
+%D We can feed this command with conversion macros as well as
+%D a set of conversion symbols. Both need a bit different
+%D treatment.
+%D
+%D \starttypen
+%D \defineconversion [roman] [\romannumerals]
+%D \defineconversion [set 1] [$\star$,$\bullet$,$\ast$]
+%D \stoptypen
+
+\def\dodefineconversion[#1][#2]%
+ {\ConvertConstantAfter\doifinstringelse{,}{#2}
+ {\scratchcounter=0
+ \def\docommando##1%
+ {\advance\scratchcounter by 1
+ \setvalue{\??cv#1\the\scratchcounter}{##1}}%
+ \processcommalist[#2]\docommando
+ \setvalue{\??cv#1}##1{\getvalue{\??cv#1##1}}}
+ {\setvalue{\??cv#1}{#2}}}
+
+\def\defineconversion%
+ {\dodoubleargument\dodefineconversion}
+
+\def\convertnumber#1%
+ {\getvalue{\??cv#1}}
+
+%D As longs as symbols are linked to levels or numbers, we can
+%D also use the conversion mechanism, but in for instance the
+%D itemization macros, we prefer symbols because they can more
+%D easier be (partially) redefined.
+
+%D We predefine some common symbols and conversions that will
+%D be understood by many commands.
+

+\definesymbol [3] [$\star$]

+%D \macros
+%D {kap,KAP,Kap,Kaps,nokap}
+%D
+%D We already introduced \type{\kap} as way to capitalize
+%D words. This command comes in several versions:
+%D
+%D \startbuffer
+%D \kap {let's put on a \kap{cap}}
+%D \kap {let's put on a \nokap{cap}}
+%D \KAP {let's put on a \\{cap}}
+%D \Kap {let's put on a \\{cap}}
+%D \Kaps{let's put on a cap}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Note the use of \type{\nokap}, \type{\\} and the nested
+%D \type{\kap}.
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D These macros show te main reason why we introduced the
+%D smaller \type{\tx} and \type{\txx}.
+%D
+%D \starttypen
+%D \kap\romeins{1995}

+%D
+%D This at first sight unusual capitilization is completely
+%D legal.

+%D \macros
+%D {stretched}
+%D
+%D Stretching characters in a word is a sort of typographical
+%D murder. Nevertheless we support this manipulation for use in
+%D for instance titles.
+%D
+%D \starttypen
+%D \hbox to 5cm{\stretched{murder}}
+%D \stoptypen
+%D
+%D \typebuffer
+%D
+%D or
+%D
+%D \startvoorbeeld
+%D \haalbuffer
+%D \stopvoorbeeld
+%D
+%D \showsetup{\y!stretched}
+
+\def\stretched%
+ {\ifvmode\hbox to \hsize\else\ifinner\else\hbox\fi\fi
+ \processtokens\relax\hss\relax\normalspace}
+
+%D \startbuffer
+%D \stretched{Unknown Box}
+%D \hbox to .5\hsize{\stretched{A Horizontal Box}}
+%D \vbox to 2cm{\stretched{A Vertical Box}}
+%D \hbox to 3cm{\stretched{sp{\'e}c{\`\i}{\"a}l}}
+%D \stopbuffer
+%D
+%D \haalbuffer
+%D
+%D The first line of this macros takes care of boxing. Normally
+%D one will use an \type{\hbox} specification. The last line
+%D shows how special characters should be passed.
+%D
+%D \typebuffer
+
+%D \macros
+%D {underbar,underbars,overstrike,overstrikes,setupunderbar}
+%D
+%D In the rare case that we need undelined words, for instance
+%D because all font alternatives are already in use, one can
+%D use \type{\underbar} and \type{\overstrike} and their plural
+%D forms.
+%D
+%D \startbuffer
+%D \underbars{drawing \underbar{bars} under words is a typewriter leftover}
+%D \overstrikes{striking words makes them \overstrike{unreadable}}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D The next macros are derived from the \PLAIN\ \TEX\ one, but
+%D also supports nesting. The \type{$} keeps us in horizontal
+%D mode and at the same time applies grouping.
+%D
+%D \showsetup{\y!underbar}
+%D \showsetup{\y!underbars}
+%D \showsetup{\y!overstrike}
+%D \showsetup{\y!overstrikes}
+%D
+%D Although underlining is ill advised, we permit some
+%D alternatives, that can be set up by:
+%D
+%D \showsetup{\y!setupunderbar}
+%D
+%D The alternatives show up as
+%D {\setupunderbar [variant=a]{alternative a},
+%D {\setupunderbar [variant=b]{alternative b},
+%D {\setupunderbar [variant=c]{alternative c}
+%D and
+%D {\setupunderbar [lijndikte=1pt]{1pt width},
+%D {\setupunderbar [lijndikte=2pt]{2pt width},
+%D or whatever. Because \type{\overstrike} uses the same
+%D method, the settings also apply to that macro.

+%D \macros
+%D {assigndimension,assignalfadimension}
+%D {}
+%D
+%D Hieronder worden enkele commando's gedefinieerd rond
+%D toekenningen. Allereerst een commando om waarden aan
+%D een \DIMENSION\ toe te kennen:
+%D
+%D \starttypen
+%D \assigndimension
+%D {<waarde>|klein|middel|groot|-klein|-middel|-groot|geen}
+%D {\dimensie}
+%D {waarde klein}
+%D {waarde middel}
+%D {waarde groot}
+%D \stoptypen
+%D
+%D Hierbij krijgt de \DIMENSION\ \type{\dimensie} een waarde
+%D afhankelijk van het meegegeven trefwoord.
+%D
+%D \startsmaller
+%D \startregels
+%D \type{(-)klein }\qquad (--) waarde klein
+%D \type{(-)middel}\qquad (--) waarde middel
+%D \type{(-)groot }\qquad (--) waarde groot
+%D \type{geen }\qquad 0pt
+%D \type{waarde }\qquad waarde
+%D \stopregels
+%D \stopsmaller
+%D
+%D Een trefwoord mag worden voorafgegaan door een \type{-}.
+%D Deze macro toont een voorbeeld van het gebruik van
+%D \type{\processaction} en constanten.
+%D
+%D Analoog aan het bovenstaande commando kennen we een
+%D commando om waarden toe te kennen aan een macro:
+%D
+%D \starttypen
+%D \assignalfadimension
+%D {<waarde>|klein|middel|groot|geen}
+%D {\macro}
+%D {waarde klein}
+%D {waarde middel}
+%D {waarde groot}

+
+%D De onderstaande implementatie is veel sneller, maar
+%D tegelijkertijd ook veel lelijker. Omdat we deze macro
+%D relatief weinig aanroepen laten we deze optimalisatie maar
+%D achterwege. Bovendien kunnen oplossingen als deze de
+%D hash||table aardig uitputten (\type{\doifdefined}).

+%D \macros
+%D {assignvalue}
+%D {}
+%D
+%D Een variant hierop is het commando:

+%D \assignvalue
+%D {<waarde>|klein|middel|groot}
+%D {\macro}
+%D {waarde klein }
+%D {waarde middel}
+%D {waarde groot}
+%D \stoptypen
+%D
+%D Hierbij krijgt \type{\macro} een waarde afhankelijk van
+%D het meegegeven trefwoord:
+%D
+%D \startsmaller
+%D \startregels
+%D \type{klein }\qquad waarde klein
+%D \type{middel}\qquad waarde middel
+%D \type{groot }\qquad waarde groot
+%D \type{waarde}\qquad waarde
+%D \stopregels
+%D \stopsmaller
+%D
+%D Hier doet \type{geen} dus niet mee.

+%D {setupfootnotes}
+%D
+%D We can influence footnote typesetting with the setup
+%D command:
+%D
+%D \showsetup{\y!setupfootnotes}
+%D
+%D It's sort of a custom to precede footnotes by a horizontal
+%D rule and although fancy rules like
+%D
+%D \starttypen
+%D \hbox to 10em{\hskip-3em\dotfill}
+%D \stoptypen
+%D
+%D Are quite ligitimate, we default to a simple one 20\% of the
+%D text width.
+%D
+%D When \type{n} exceeds~1, footnotes are typeset in
+%D multi||columns, using the algoritm presented on page~397
+%D of \TEX book. Footnotes can be places on a per page basis
+%D or whereever suitable. When we set~\type{n} to~0, we get a
+%D rearanged paragraph, typeset by the algoritms on pages 398
+%D and~389. We definitely did not reinvent that wheel.

+%D Both these parameters are coupled to the setup command we
+%D will implement in a moment. This means that, given a
+%D suitable symbol set, symbols can be used instead of numbers,
+%D by saying:
+%D
+%D \starttypen
+%D \setupfootnotes[conversion=set 2]
+%D \stoptypen
+
+%D \macros
+%D {footnote}
+%D
+%D A footnote can have a reference as optional argument and
+%D therefore its formal specification looks like:
+%D
+%D \showsetup{\y!footnote}
+%D
+%D This command has one optional command: the reference. By
+%D saying \type{[-]} the number is omitted. The footnote
+%D command is not that sensitive to spacing, so it's quite
+%D legal to say:
+%D
+%D \startbuffer
+%D Users of \CONTEXT\ must keep both feet \footnote{Given they
+%D have two.} on the ground and not get confused \footnote{Or
+%D even crazy.} by all those obscure \footnote{But fortunately
+%D readable.} parameters.
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D When setting the \type{conversion} to \type{set 2} we get
+%D something like:
+%D
+%D \bgroup
+%D \startsmaller
+%D \stelvoetnotenin[conversie=set 1]
+%D \haalbuffer
+%D \stopsmaller
+%D \egroup
+%D
+%D Typesetting footnotes is, at least for the moment, disabled
+%D when reshaping boxes.

+%D \macros

+%D
+%D Before we come to typesetting a footnote, we first check
+%D if we have to typeset a number. When a \type{-} is passed
+%D instead of a reference, no number is typeset. We can
+%D temporary disable footnotes by saying
+%D
+%D \starttypen
+%D \footnotesenabledfalse
+%D \stoptypen
+%D
+%D which can be handy while for instance typesetting tables
+%D of contents.

+%D The main typesetting routine is more or less the same as the
+%D \PLAIN\ \TEX\ one, except that we only handle one type while

+%D footnotes can be handled by a straight insert, but we do so
+%D by using an indirect call to the \type{\insert} primitive.
+
+\let\localfootinsert=\insert
+
+%D Making footnote numbers active is not always that logical,
+%D especially when we keep the reference and text at one page.
+%D On the other hand we need interactivity when we refer to
+%D previous notes or use end notes. Therefore we support
+%D interactive footnote numbers in two ways \voetnoot{This
+%D feature was implemented years after we were able to do so,
+%D mainly because endnotes had to be supported.} that is,
+%D automatically (vise versa) and by user supplied reference.

+%D \macros
+%D {note}
+%D
+%D Refering to a note is accomplished by the rather short
+%D command:
+%D
+%D \showsetup{\y!note}
+%D
+%D This command is implemented rather straightforward as:
+
+\def\note[#1]%
+ {\iffootnotesenabled
+ \bgroup
+ \unskip
+ \gettextreference{#1}%
+ \naarbox{\hoog{\currenttextreference}}[#1]%
+ \egroup
+ \fi}
+
+%D Normally footnotes are saved as inserts that are called upon
+%D as soon as the pagebody is constructed. The footnote
+%D insertion routine looks just like the \PLAIN\ \TEX\ one,
+%D except that we check for the end note state.
+
+\let\startpopfootnotes = \relax

+ \startpopfootnotes
+ \unvbox\footins
+ \stoppopfootnotes

+ \@@vnna

+ \fi}
+
+%D Supporting end notes is surprisingly easy. Even better, we
+%D can combine this feature with solving the common \TEX\
+%D problem of disappearing inserts when they're called for in
+%D deeply nested boxes. The general case looks like:
+%D
+%D \starttypen
+%D \postponefootnotes
+%D \.box{whatever we want with footnotes}
+%D \flushfootnotes
+%D \stoptypen
+%D
+%D This alternative can be used in headings, captions, tables
+%D etc. The latter one sometimes calls for notes local to
+%D the table, which can be realized by saying
+%D
+%D \starttypen
+%D \setlocalfootnotes
+%D some kind of table with local footnotes
+%D \placelocalfootnotes
+%D \stoptypen
+%D
+%D Postponing is accomplished by simply redefining the (local)
+%D insert operation. A not too robust method uses the
+%D \type{\insert} primitive when possible. This method fails in
+%D situations where it's not entirely clear in what mode \TEX\
+%D is. Therefore the auto method can is to be overruled when
+%D needed.

+
+%D These commands can be used like:
+%D
+%D \startbuffer
+%D \startlocalfootnotes[breedte=.3\hsize,n=0]
+%D \plaatstabel
+%D {Some Table}
+%D \plaatsonderelkaar
+%D {\starttabel[|l|r|]

+%D \HL
+%D \stoptabel}
+%D {\placelocalfootnotes}
+%D \stoplocalfootnotes
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Because this table placement macro expect box content, and
+%D thanks to the grouping of the local footnotes, we don't need
+%D additional braces.
+%D
+%D \haalbuffer
+
+%D \macros
+%D {placefootnotes}
+%D
+%D We still have no decent command for placing footnotes
+%D somewhere else than at the bottom of the page (for which no
+%D user action is needed). Footnotes (endnotes) can be
+%D placed by using
+%D
+%D \showsetup{\y!placefootnotes}
+
+\def\doplacefootnotes[#1]%
+ {\bgroup
+ \setupfootnotes[#1]%
+ \ifendnotes
+ \ifinpagebody \else
+ \placefootnotesintext\postponedfootnotes
+ \fi
+ \else
+ \placefootnoteinserts
+ \fi
+ \egroup}
+
+\def\placefootnotes%
+ {\dosingleempty\doplacefootnotes}
+
+%D Now how can this mechanims be hooked into \CONTEXT\ without
+%D explictly postponing footnotes? The solution turned out to
+%D be rather simple:
+%D
+%D \starttypen
+%D \everypar {...\flushfootnotes...}
+%D \neverypar {...\postponefootnoes}
+%D \stoptypen
+%D
+%D and
+%D
+%D \starttypen
+%D \def\ejectinsert%
+%D {...
+%D \flushfootnotes
+%D ...}
+%D \stoptypen
+%D
+%D We can use \type{\neverypar} because in most commands
+%D sensitive to footnote gobbling we disable \type{\everypar}
+%D in favor for \type{\neverypar}. In fact, this footnote
+%D implementation is the first to use this scheme.
+
+%D When typesetting footnotes, we have to return to the
+%D footnote specific corps size, which is in most cases derived
+%D from the global document corps size. In the previous macros
+%D we already used a footnote specific font setting macro.
+
+\def\setfootnotecorps%
+ {\restoreglobalcorps
+ \switchtocorps[\@@vnkorps]}
+
+%D The footnote mechanism defaults to a traditional one
+%D column way of showing them. By default we precede them by
+%D a small line.

+%D characteristics.
+%D

+%D \TEX\ lacks support for color and even gray scales. The next
+%D macros can provide a sort of poor mans gray scales as well
+%D as give access to more suitable methods of rendering. Such a
+%D method looks like:
+%D
+%D \starttypen
+%D \def\methodegraybox\width#1\depth#2\height#3\raster#4\radius#5\\
+%D { ... }
+%D \stoptypen
+%D
+%D The string \type{graybox} is a common element in the name,
+%D so we can have for instance \type {\postscriptgraybox} or
+%D \type {\texgraybox}. The first three arguments take a
+%D dimension, the fourth one takes a number between~0 and~1,
+%D and the last argument specifies a radius of the box when
+%D rounded corners are used, so:
+
+%D \startbuffer
+%D \periodgraybox\width.5\hsize\height1cm\depth0cm\raster.85\radius0pt\\
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D becomes:
+%D
+%D %\startregelcorrectie
+%D % \vbox to 1cm{\haalbuffer}
+%D %\stopregelcorrectie
+%D
+%D \startregelcorrectie
+%D \unprotect
+%D \vbox to 1cm
+%D {\getvalue{\v!punt graybox}\width.5\hsize\height1cm\depth0cm\raster.85\radius0pt\\}
+%D \protect
+%D \stopregelcorrectie
+%D
+%D There are two predefined methodes, one uses periods and the
+%D other uses small rules. The second method is less
+%D efficient, but sometimes give better results. The dimensions
+%D of the resullting box are set to zero.

+%D Now of course we need:
+
+\ifx\rasterfont\undefined \def\rasterfont{\fivepoint} \fi
+
+%D We implement two pure \TEX\ based generators, that use
+%D \type{\leaders} to quickly gerenate the gray pattern. One
+%D should beware of \DIMENSION\ conflicts, so we use some
+%D registers above~8. These macros are memory hungry and byte
+%D spoiling.

+\def\setupscreens%

+%D The most appropriate way to call for this feature is

+
+%D This macro takes the five arguments mentioned earlier and
+%D obey the user's settings.
+
+%D We just introduced two pure \TEX\ methods for generating
+%D rasters. However, it's far more efficient and comfortable in

+ {\setgraybox\width#1\height#2\depth#3\raster#4\corner#5\radius#6\\}
+
+%D For compatibility reasons we also define the original one:
+
+\setvalue{\v!postscript graybox}%
+ {\getvalue{\v!extern graybox}}
+
+%D A quite valid way of letting drivers do the job, is giving
+%D a solid rule a gray texture.

+%D
+%D The formal definition is:
+%D
+%D \showsetup{\y!defineoverlay}
+%D
+%D This macro's definition is a bit obscure, due the many
+%D non||used arguments and the two step call that enable the
+%D setting of the width, height and depth variables.

+%D The empty case is:

+\def\executeoverlay#1#2#3#4#5#6#7%

+%D We predefine two already familiar backgrounds:

+%D After all these preparations, the background macro does no
+%D bring to many surprises. One has to keep in mind that this
+%D macro starts up a call chain, depending on the background
+%D one needs:
+%D
+%D \startopsomming[opelkaar]
+%D \som a raster, color or user defined shape
+%D \som square or round corners
+%D \som a \TEX\ or driver based method
+%D \stopopsomming

+%D I condidered using the low level support command
+%D \type{\ruledhbox}, but this would slow down processing by a
+%D factor~3.
+
+%D Before we come to using these macros we yet have to define
+%D the rounded corner alternative, which after all is not that
+%D hard because it uses the previously defined macro \type
+%D {\ovalbox}.
+
+\def\dostrokedroundbox\width#1\height#2\depth#3\radius#4\\%
+ {\ovalbox{#1}{#2}{#3}{\linewidth}{#4}{\v!ja}{\v!nee}}
+
+%D The next few macros are probably the most misused ones in
+%D \CONTEXT. They deal with putting rules around boxes, provide
+%D backgrounds, offer alignment features, and some more. We
+%D start with defining some booleans. These give an impression
+%D of what we are going to take into account.

+%D is quite versatile and, although some users will probably
+%D seldom use it, one cannot overlook its features.
+%D
+%D \showsetup{\y!setupframed}
+%D \showsetup{\y!framed}
+%D
+%D This general macro is a special version of an even more
+%D general case, that can easily be linked into other macros
+%D that need some kind of framing. The local version is called
+%D with an extra parameter: the variable identifier. The reason
+%D for passing this identifier between brackets lays in the
+%D mere fact that this way we can use the optional argument
+%D grabbers.

+%D The normal case first presets all parameters and next starts
+%D looking for the user supplied ones. The first step is
+%D omitted in the local case, because these are preset at

+%D
+%D The last few lines tell what to do after the content of the

+%D So now we're ready for the complicated stuff. We distinguish
+%D between borders with straight lines and those with round
+%D corners. When using the first alternative it is possible to
+%D turn off one or more lines. More fancy shapes are also
+%D possible by specifying dedicated backgrounds. Turning lines
+%D on and off is implemented as efficient as possible and as a
+%D result is interface language dependant. This next
+%D implementation evolved from simpler ones. It puts for
+%D instance the rules on top of the content and provides
+%D additional offset capabilities. The lot of calls to other
+%D macros makes this mechanism not that easy to comprehend.

+%D of a centered box automatically (\type{\v!passend}). When
+%D doing so, we need to reshape the box:

+
+%D The examples on the next page show how one can give the
+%D frame as well as the background an additional offset and
+%D even a bit more depth. The blue outline is the frame, the
+%D red box is the background and the small black outline is the
+%D vsiualization of the resulting box, that is, we applied
+%D \type{\ruledhbox} to the result.

+%D
+%D The graphic capabilities of \TEX\ do not go beyond simple
+%D filled rules, except of course when using specials. Let's
+%D start with a warning: using this commands is far more slower
+%D than using the \TEX\ primitives \type{\hrule} and
+%D \type{\vrule}, but they save us some tokens. The
+%D characteristics of these rule drawing command can be set by:
+%D
+%D \showsetup{\y!setupblackrules}
+
+\def\setupblackrules%
+ {\dodoubleargument\getparameters[\??bj]}
+
+%D \macros
+%D {blackrule}
+%D
+%D The simple command draws only one rule. Its optional
+%D argument can be used to specify the dimensions. By setting
+%D the width, height or depth to \type{\v!max}, one gets the
+%D natural dimensions.

+%D sensitive, but the next command handles that quite well. It
+%D comes in to disguises:

+%D
+%D The section deals with backgrounds in the running text. This
+%D means that texts is to be collected and split over pages. To
+%D show what can be done, we provide this part of the
+%D documentation with some gray background and a red frame.
+%D Both the background and frame can have all characteristics
+%D of \type{\framed}. This time we used the setting:
+%D
+%D \typebuffer
+%D
+%D The implementation is not that sophisticated, but suffices.
+%D The main problem with this kind of functionality is to get
+%D the spacing all right.
+
+%D Specifying the background is more or less the same as
+%D specifying a framed box.

+
+\def\setupbackground%
+ {\dosingleargument\dosetupbackground}
+
+%D Actually typesetting the background is implemented rather
+%D straightforward. We need to handle some spacing as well as
+%D the (often) a bit smaller horizontal size.
+%D
+%D \showsetup{\y!startbackground}
+%D
+%D Although we could have used a scratch one, we first
+%D declare a boolean.

+%D This dummy line is removed by \type{\setbox2=\vsplit0 to

+%D lineheight. I'll probably forget to apply this trick
+%D elsewhere.

+%D We felt no need to write our own table building macros,
+%D simply because Michael Wichura made a terrific one. This
+%D package is quite complete and well documented. In \CONTEXT\
+%D we provide a shell for consistent spacing as well as color
+%D support. Implementing these features without adapting the
+%D original macros is not trivial. One easilly gets conflicts
+%D with \type{\omit}, \type{\span} and \type{\noalign}, which
+%D means that we end up postponing and overloading macros,
+%D mostly global. Now, let's start with loading the main
+%D macros:
+
+\doifundefined{BeginTable}{\doinputonce{table.tex}}
+
+\unprotect
+
+%D \macros
+%D {inintable, ifsplittable}
+%D
+%D First we declare some variables. These show a bit what we
+%D are dealing with. First we introdoce some booleans that
+%D enable us, inside as well as outside this module, to
+%D determine in what mode we are.
+
+\newif\ifintable
+\newif\ifsplittables
+
+%D \macros
+%D {iftracetable}
+%D
+%D When I documented this module, I felt the need for tracing
+%D options. After implementing this feature, I also added
+%D warnings, error recovery and automatic spacing.
+
+\newif\iftracetables
+
+%D We show this feature in an eample that also shows some of
+%D the basic table typesetting commands.

+%D This table is specified as:
+%D
+%D \typebuffer
+%D
+%D This examples shows about the minimum of commands needed to
+%D typeset such a table. In this table, the \type {\AR} is
+%D automatically translated into the more primitive (but more
+%D verbose) commands \type {\SR}, \type {\FR}, \type {\MR} and
+%D \type {\LR} commands.

+%D information.
+%D
+%D {\tracetablesfalse\haalbuffer}
+%D
+%D Sometimes in tables information shows up that is not typed
+%D in by the user. These messages give a cue in what aspect a
+%D table definition is wrong.

+%D
+%D Those terrible table has three errors, which all show up in
+%D typeset messages. Errors cannot always recovered 100\% and
+%D therefore can result in two or more succesive messages, like
+%D in the last row.
+%D
+%D \haalbuffer
+
+%D Bringing color into tables is complicated by the mere fact
+%D that color is not part of \TEX. The main complication is
+%D that we don't know in advance how wide a column will be. I
+%D implemented color support in tables in the early 90's
+%D because I needed it for some articles on color. I have to
+%D admit that I seldom use the mechanism.
+%D
+%D Most color support in \CONTEXT\ makes use of colored rules.
+%D At first sight, one is tempted to implement colors in tables
+%D in a similar way, but as said, we don't know the dimensions
+%D in advance. It turns out however that we don't have to,
+%D simply because alignments take care of stretching rules to
+%D the appropritate dimensions. This means that we can provide
+%D backgrounds by coloring rules with the height of a row,
+%D skipping upwards and finally drawing the content, like in:

+%D In these examples we can clearly see that for being a real
+%D background, the color or gray specification has to precede
+%D the content. Just to keep things simple, we can recall this
+%D specification later on:

+%D Close study learns that we can put the specification
+%D before or after the \type{\HL}, whatever suits best. Keeping
+%D track of these specifications is taken care of by the next
+%D variables:
+
+\newif \ifTABLEgrayline % executing gray line
+\newif \ifTABLEgraydone % gray line executed
+\newtoks \TABLEgraytoks % gray line specification
+
+%D A third major extension, besides spacing and color support,
+%D concerns splitting tables over pages. We don't give
+%D examples here, because its a waste of space.
+
+\newdimen\TABLEheight % These can be \newskimens
+\newdimen\TABLEmaxheight % given a few \relax's when
+\newdimen\TABLEheadheight % testing them with \ifdim.
+\newdimen\TABLEtailheight
+\newdimen\TABLEcaptionheight
+
+\newif\ifTABLEinbreak
+
+%D Nog vervangen:
+
+\def\c!Table {Table}
+
+%D We alraady saw that the table macros report errors and
+%D provide automatic spacing. These features can only be
+%D implemented by keeping track of the state, often the last
+%D command on a row.
+
+\chardef\TABLEunknown = 0
+
+\chardef\TABLEseparaterow = 1
+\chardef\TABLEfirstrow = 2
+\chardef\TABLEmidrow = 3

+\chardef\TABLEforcelastrow = 2
+
+\chardef\TABLEmissingrow = 1
+\chardef\TABLEmissingcolumn = 2
+\chardef\TABLEspanoverflow = 3
+\chardef\TABLEdivisionoverflow = 4
+
+%D We store these states using efficient \type {\chardef}'s.
+%D Like most variables, these are global ones. When needed,
+%D especially when we flush the backgrounds, we can temporary
+%D disable the assignment.
+
+\newif\ifsetTABLEaction
+
+\def\setTABLEaction#1%
+ {\ifsetTABLEaction\global\chardef\TABLEaction#1\fi}
+
+\def\setTABLEforce#1%
+ {\ifsetTABLEaction\global\chardef\TABLEforce#1\fi}
+
+\def\setTABLEerror#1%
+ {\global\chardef\TABLEerror#1}
+
+%D Before we come to using these variables, we redefine and/or
+%D adapt some \TABLE\ macros. Within \TABLE's the \type{|} and
+%D \type{"} have special meanings in templates and are active
+%D during. Their meaning can therefore conflict with those
+%D elsewhere defined. To be compatible with traditional \TABLE\
+%D as well as \CONTEXT's \type{||} and the active \type{"}
+%D extensions for my german friends, we do some catcode magic.

+ \fi}
+\egroup
+
+%D \macros
+%D {ObeyTableBarAndQuote}
+%D
+%D As said, the \type{|} and \type{"} active characters are
+%D often used for other purposes. By default, the outside
+%D meanings are therefore preserved and available inside
+%D tables. If for some reason one wants to use the \TABLE\
+%D primitives, one can say:
+%D
+%D \starttypen
+%D \ObeyTableBarAndQuote
+%D \stoptypen
+%D
+%D To keep things verbose, as well as to show what \TABLE\
+%D commands we affect, we show some meanings.

+
+%D To give an impression of what the (well documented) source
+%D of \TABLE\ looks like, we first implement an alternative for
+%D the numeric keys. The quantity keys (\type{q} and \type{Q})
+%D support the more european way of writing numbers:
+%D
+%D \startsmaller
+%D 100.000.000,00 instead of 100,000,000.00
+%D \stopsmaller
+%D
+%D The next table shows how to use these keys. We use braces
+%D instead of brackets because we need brackets to specify the
+%D format.
+%D
+%D \startbuffer
+%D \starttabel{|q[00,000]|Q[00,00]|}

+%D \stopbuffer
+%D
+%D \ShowExample
+%D
+%D Although a more efficient implementation is possible |<|we
+%D can for instance share common macros|>| we just adapt a copy
+%D of the numeric ones. To permit double loading of this
+%D module, we check for the existence of one of the macros.

+%D Here ends the Q||extension. Did you watch the clever use

+% %D We also (have to) define a key for \type{\kap}:
+%
+% \letvalue{!tk<\string K>}=\undefined
+%
+% \NewFormatKey K%
+% {\ReadFormatKeys b\kap}
+
+%D A few pages back we saw backgrounds, further on we will see
+%D colored rules, and here we provide a means to color the
+%D entries in a column. (We can of course always use the normal
+%D color commands for individual entries.) We could not use the
+%D lowercase~\type{c}, because that one is used to force {\em
+%D centering}.
+%D
+%D \startbuffer
+%D \starttabel[|C{red}|C{green}|C{blue}|]

+%D
+%D \starttabel[|||]
+%D \HL
+%D \NC \bf key \NC \bf meaning \NC\AR
+%D \HL
+%D \NC Q[x,y] \NC math mode formatted numbers \NC\AR
+%D \NC q[x,y] \NC text mode formatted numbers \NC\AR
+%D \NC C{identifier} \NC column entry color \NC\AR
+%D \HL
+%D \stoptabel
+
+%D Later on, we're going to implement multiple page table
+%D support, therefore the next \TABLE\ macro needs to be
+%D slightly adapted, i.c. the penalty is removed.
+
+\def\!ttFullHruleA%
+ {\!ttGetHalfRuleThickness
+ \hrule\!thHeight\dimen0\!thDepth\dimen0
+ %\penalty0
+ \egroup}
+
+%D We'll see that when we want to give a vertical rule a color,
+%D we have to set and reset states. After heavy testing it
+%D proved most useful to extend a \TABLE\ primitive with some
+%D hooks. One thing to keep in mind is that \type{&} keeps
+%D assignments local.
+
+\let\TABLEbeforebar=\empty
+\let\TABLEafterbar =\empty

+%D We already shows the next one, but here we slightly adapt
+%D the macro by adding an \type{\expandafter}. The space after
+%D \type{#1} is crucial!
+
+\def\normalTABLEcomplexbar#1%
+ {\unskip\!ttRightGlue&\omit\expandafter\!ttAlternateVrule#1 }
+
+%D To get rid of interfering \type{\omit}'s when we are
+%D checking the number of columns and reporting problems. The
+%D extensions concern the second level check, the first
+%D subbranch and advancing the column.

+%D All commands that are executed between rows are to be put in
+%D \type {\noalign}. We can however not verify if we (that is
+%D \TABLE) does or did not enter this mode. A moderate dirty
+%D but useful trick is using our own alternative:\voetnoot{Once
+%D one has entered the stage of redefining \TEX\ primitives,
+%D such hacks become a second nature. However, redefining \type
+%D {\omit} and \type{\span} is not that easy.}

+%D \macros
+%D {starttable}
+%D
+%D The rest of this module is not easy to comprehend, mainly
+%D because we have to take care of:
+%D
+%D \startopsomming[opelkaar]
+%D \som \type{\startopsomming[template]}
+%D \som \type{\startopsomming{template}}
+%D \som \type{\startopsomming[predefined]}
+%D \stopopsomming
+%D
+%D as well as:
+%D
+%D \startopsomming[verder]
+%D \som restart after table break
+%D \stopopsomming
+%D
+%D The official specification of the start command is:

+%D \macros
+%D {definetabletemplate}
+%D
+%D The complex (and main) start macro first takes care of the
+%D predefined case. Such a predefined setup looks like:
+%D
+%D \starttypen
+%D \definetabletemplate[test][|||]
+%D
+%D \starttabel[test]
+%D \VL test \VL test \VL\AR
+%D \VL test \VL test \VL\AR

+%D \stoptabel

+%D
+%D The implementation of the definition macro is not that
+%D complicated:
+
+\def\dodefinetabletemplate[#1][#2]%

+ \egroup}
+
+\def\definetabletemplate%
+ {\bgroup
+ \catcode`\|=\@@other
+ \dodoubleargument\dodefinetabletemplate}
+
+%D Templates defined this way get protected names, that cannot
+%D conflict with existing commands.
+%D
+%D \showsetup{\y!definetabletemplate}

+%D The second half of the next macro prepares table
+%D splitting.

+%D The preparation for split columns concerns some
+%D calculations. Although not explicitly needed, one can
+%D predefine a tablehead as well as a tail. Each table fragment
+%D is preceded by such a head and ends with a tail. This means
+%D that, in order to determine the available heigth, we have to
+%D take the head and tail into account. Because we want to
+%D support captions too, we will also reserve some space for
+%D those later on.

+%D \macros
+%D {starttables}
+%D
+%D Split tables are specified using the plural form of the
+%D start and stop commands.
+%D
+%D \showsetup{starttables}
+%D
+%D For example:
+%D
+%D \starttypen
+%D \starttabellen[|||]
+%D \HL
+%D \VL element \VL atom weight \VL\AR
+%D \HL
+%D \VL ....... \VL ........... \VL\AR
+%D \VL ....... \VL ........... \VL\AR
+%D \HL
+%D \stoptabellen
+%D \stoptypen
+
+\def\starttabellen%
+ {\bgroup
+ \ifinsidefloat\else
+ \baselinecorrection
+ \flushfootnotes
+ \topbaselinecorrection
+ \fi
+ \forgetall
+ \global\let\absmaxTABLEheight=\!!zeropoint
+ \splittablestrue
+ \global\TABLEinbreakfalse
+ \firststagestartTABLE}
+
+\def\stoptabellen%
+ {\TABLEtail
+ \finishTABLE
+ \ifinsidefloat\else
+ \flushfootnotes
+ \botbaselinecorrection
+ \fi
+ \egroup}
+
+%D When the table in the previous example is split across
+%D pages, only the first gets a head. We could have said
+%D something like:
+%D
+%D \starttypen
+%D \starttabelkop
+%D \HL
+%D \VL element \VL atom weight \VL\AR
+%D \HL
+%D \stoptabelkop
+%D
+%D \starttabelstaart
+%D \HL
+%D \stoptabelstaart
+%D
+%D \starttabellen[|||]
+%D \VL ....... \VL ........... \VL\AR
+%D \VL ....... \VL ........... \VL\AR
+%D \stoptabellen
+%D \stoptypen
+%D
+%D This time each split table gets a head line and ends with
+%D a rule. Keep in mind that such heads also apply to the
+%D unbroken ones and should be defined local (grouped) if
+%D needed. The rather complicated definition below is due to
+%D the fact that the stopcondition is interface language
+%D dependant.
+
+\let\TABLEhead =\empty
+\let\TABLEtail=\empty
+
+\letvalue{\e!start \e!tabelkop}=\undefined
+\letvalue{\e!stop \e!tabelkop}=\undefined
+\letvalue{\e!start\e!tabelstaart}=\undefined

+ {\noexpand\def\noexpand\TABLEtail{##1}}}
+
+%D Redudant \type{\HL}'s are removed automatically, so
+%D mid||lines can be used without problems.
+
+%D When calculating the available height of a split table, we
+%D try to handle multi||column mode as good as possible. This
+%D algoritm evolved during the development of the split option
+%D and will probably be improved bit by bit.

+%D \sym{\type{\MR}} end a mid row (between text lines)

+%D \stopopsomming
+%D
+%D and best of all:
+%D
+%D \startopsomming[verder]
+%D \sym{\type{\AR}} end a row with automatic spacing
+%D \stopopsomming
+%D
+%D As far as possible, we report confusing situations. In
+%D most cases one can use \type{\AR}, which transfigurates
+%D itself into one of the other types.

+%D \VL a first row \VL\FR

+%D
+%D In this example we could have used \type{\AR} without
+%D problems.
+%D
+%D Color or gray scale backgrounds precede the content. They
+%D are passed over horizontal (division) lines when needed.
+%D Errors in the color template are traced elsewhere. Here we
+%D only check for inconsistent spacing. Due to the way \TEX\
+%D handles alignments, we cannot automate spacing for colored

+%D We are going to embed the general verbatim support macros in
+%D a proper environment. First we show the common setup
+%D macro, so we know what features are supported. The options
+%D are hooked into the support macros via the \type{\obey}
+%D macros.

+%D The verbatim commands have a rather long and turbulent
+%D history. Most users of \CONTEXT\ probably will never use
+%D some of the features, but I've kept in mind that when one is
+%D writing a users manual, about everything can and undoubtly
+%D will be subject to a verbatim treatment.
+%D
+%D Verbatim command are very sensitive to argument processing,
+%D which is a direct result of the \CATCODES\ being fixed at
+%D reading time. With our growing understanding of \TEX,
+%D especially of the mechanism that can be used for looking
+%D ahead and manipulating \CATCODES, the verbatim support
+%D became more and more advanced and natural.
+%D
+%D Typesetting inline verbatim can be accomplished by
+%D \type{\type}, which in this sentence was typeset by saying
+%D just \type{\type{\type}}, which in turn was typeset by
+%D \onbekend. Using the normal grouping characters \type{{}} is
+%D the most natural way of using this command.
+%D
+%D A second, more or less redundant, alternative is delimiting
+%D the argument with an own character. This method was
+%D implemented in the context of a publication in the \MAPS,
+%D where this way of delimiting is recognized by \LATEX\ users.
+%D
+%D The third, more original alternative, is the one using
+%D \type{<<} and \type{>>} as delimiters. This alternative can
+%D be used in situations where slanted typeseting is needed.

+%D When writing the manual to \CONTEXT\ and documenting this
+%D source we needed to typeset \type{<<} and \type{>>}. Because
+%D we wanted to do this in the natural way, we've adapted the
+%D original definition a bit. We still show teh original
+%D because we think it's shows a bit better what we are

+%D Sometimes, for instance when we pass verbatim text as an
+%D argument, the fixed \CATCODES\ interfere with our wishes. An
+%D experimental implementation of character by character
+%D processing of verbatim text did overcome this limitation,
+%D but we've decided not to use that slow and sometimes
+%D troublesome solution. Instead we stick to some 'old'
+%D \CONTEXT\ macros for typesetting typical \TEX\ characters.

+%D In the documentation of the verbatim support module we give

+%D {typefile}

+%D
+%D Typesetting files verbatim (for the moment) only supports
+%D colorization of \TEX\ sources as valid option. The other
+%D setup values are inherited from display verbatim.
+%D The implementation of \type{\typefile} is straightforward:
+
+\presettyping[\v!file][]

+\def\typefile#1%
+ {\getvalue{\??tp\v!file\c!voor}%
+ \startopelkaar % includes \bgroup

+ \processfileverbatim{#1}%
+ \stopopelkaar % includes \egroup

+
+\setuptype
+ [\c!spatie=\v!uit,
+ \c!pagina=\v!nee,
+ \c!tab=\v!nee,
+ \c!optie=\v!normaal]
+
+%D The setups for display verbatim and file verbatim are
+%D shared. One can adapt the extra defined typing environments,
+%D but they also default to the values below. Watch the

+%D \TeX\ acts upon paragraphs. In mosts documents paragraphs
+%D are separated by empty lines, which internally are handled as
+%D \type{\par}. Paragraphs can be indented or not, depending on
+%D the setting of \type{\parindent}, the first token of a
+%D paragraph and/or user suppressed or forced indentation.
+%D
+%D Because the actual typesetting is based on both explicit
+%D user and implicit system actions, visualization is only
+%D possible for the user supplied \type{\indent},
+%D \type{\noindent}, \type{\leavevmode} and \type{\par}. Other
+%D 'clever' tricks will quite certainly lead to more failures
+%D than successes, so we only support these three explicit
+%D primitives and one macro:

+%D either within an \AMSTEX\ document style file or by itself,
+%D in addition to providing a means of testing whether the file
+%D has been previously loaded. We want to avoid inputting this
+%D file twice because when \AMSTEX\ is being used
+%D \type{\newsymbol} will give an error message if used to
+%D define a control sequence name that is already defined.
+
+%D If the csname is not equal to \type{\relax}, we assume this
+%D file has already been loaded and \type{\endinput}
+%D immediately.
+
+\expandafter\ifx\csname pre amssym.tex at\endcsname\relax \else \endinput\fi
+
+%D Otherwise we store the catcode of the @ in the csname.
+
+\expandafter\chardef\csname pre amssym.tex at\endcsname=\the\catcode`\@
+
+%D Set the catcode to 11 for use in private control sequence
+%D names.
+
+\catcode`\@=11
+
+%D Most symbols in fonts msam and msbm are defined using
+%D \type{\newsymbol}. A few that are delimiters or otherwise
+%D require special treatment have already been defined as soon
+%D as the fonts were loaded. Finally, a few symbols that
+%D replace composites defined in plain must be undefined first.

+%D This module is one of the oldest modules of \CONTEXT. The
+%D macros below evolved out of the \PLAIN\ \TEX\ macros and
+%D therefore use a similar naming scheme (\type{\rm},
+%D \type{\bf}, etc). This module grew out of our needs. We
+%D started with the \PLAIN\ \TEX\ definitions, generalized the
+%D underlaying macros, and extended those to a level at which
+%D probably no one will ever recognize them.
+%D
+%D One important characteristic of the font mechanism presented
+%D here is the postponing of font loading. This makes it
+%D possible to distribute \type{fmt} files without bothering
+%D about the specific breed of \type{tfm} files.
+%D
+%D Another feature implemented here is the massive switching
+%D from roman to {\ss sans serif}, {\tt teletype} or else. This
+%D means one doesn't have to take care of all kind of relations
+%D between fonts.
+
+%D \macros
+%D {rm,ss,tt,hw,cg}
+%D
+%D Fonts are defined in separate files. When we define a font,
+%D we distinguish between several styles. In most cases we will
+%D use:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC roman \NC \type{\rm} \NC\FR
+%D \NC sansserif \NC \type{\ss} \NC\MR
+%D \NC type \NC \type{\tt} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D The number of styles is not limited to these three. When
+%D using Lucida Bright we can for instance also define:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC handwritten \NC \type{\hw} \NC\FR
+%D \NC calligraphy \NC \type{\cg} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D Anyone who feels the need, can define additional ones, like
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC faxfont \NC \type{\ff} \NC\FR
+%D \NC blackboard \NC \type{\bb} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D Or even
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC hebrew \NC \type{\hb} \NC\SR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D Styles are grouped in font sets. At the moment there are
+%D three main sets defined:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l|l||]
+%D \HL
+%D \NC Computer Modern Roman \NC Knuth \NC \type{cmr} \NC\FR
+%D \NC Lucida Bright \NC Bigelow \& Holmes \NC \type{lbr} \NC\MR
+%D \NC Standard Postscript Fonts \NC Adobe \NC \type{pos} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D There are also some Computer Modern Roman alternatives:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l|l||]
+%D \HL
+%D \NC Computer Modern Roman \NC Knuth \& Sauter \NC \type{sau} \NC\FR
+%D \NC Euler fonts \NC Zapf \NC \type{eul} \NC\MR
+%D \NC Computer Modern Concrete \NC Knuth \& Zapf \NC \type{con} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D All these definitions are ordered in files with names like
+%D \type{font-cmr} and \type{font-pos}, where the last three
+%D characters specifiy the name as known to \CONTEXT.
+%D
+%D Within such a font set (\type{cmr}) and style (\type{\rm})
+%D we can define a number of text font alternatives:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC typeface \NC \type{\tf} \NC\FR
+%D \NC boldface \NC \type{\bf} \NC\MR
+%D \NC slanted \NC \type{\sl} \NC\MR
+%D \NC italic \NC \type{\it} \NC\MR
+%D \NC boldslanted \NC \type{\bs} \NC\MR
+%D \NC bolditalic \NC \type{\bi} \NC\MR
+%D \NC smallcaps \NC \type{\sc} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+
+%D The more primitive is (still) predefined:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC oldstyle \NC \type{\os} \NC\SR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D The availability of these alternatives depends on the
+%D completeness of a font family and of course the definitions
+%D in the font files.
+%D
+%D But let's not forget math. In addition to the previous \TEX\
+%D families (the mysterious \type{\fam}'s) we've got some more:
+%D
+%D \startregelcorrectie
+%D \starttabel[|l||]
+%D \HL
+%D \NC Math Roman \NC \type{\mr} \NC\FR
+%D \NC Math Italic \NC \type{\mi} \NC\MR
+%D \NC Math Symbol \NC \type{\sy} \NC\MR
+%D \NC Math Extra \NC \type{\ex} \NC\MR
+%D \NC Math A \NC \type{\ma} \NC\MR
+%D \NC Math B \NC \type{\mb} \NC\MR
+%D \NC Math C \NC \type{\mc} \NC\LR
+%D \HL
+%D \stoptabel
+%D \stopregelcorrectie
+%D
+%D Users can call for specific fonts in many ways. Switches to
+%D other typefaces, like the switch from normal to bold, are as
+%D intuitive as possible, which means that all dependant fonts
+%D also switch. One can imagine that this takes quite some
+%D processing time.
+%D
+%D Internally fonts are stored as combination of size, style
+%D and alternative, e.g. \type{12pt}+\type{\ss}+\type{\bf}.
+%D Users are not confronted with sizes, but use the style or
+%D style+alternative to activate them.
+%D
+%D During the definition of a corps one can also declare the
+%D available larger alternatives:
+%D
+%D \starttypen
+%D \tf \tfa \tfb \tfc ...
+%D \bf \bfa \bfb \bfc ...
+%D \sl \sla \slb \slc ...
+%D \stoptypen
+%D
+%D The smaller ones are automatically supplied and derived from
+%D the the corps environment.
+%D
+%D \starttypen
+%D \tfx \tfxx
+%D \bfx \bfxx
+%D \slx \slxx
+%D \stoptypen
+%D
+%D There are only two smaller alternatives per style. The
+%D larger alternatives on the other hand have no limitations.
+%D
+%D These larger alternatives are mostly used in chapter and
+%D section titles or on title pages. When one switches to a
+%D larger alternative, the bold an other ones automatically
+%D adapt themselves:
+%D
+%D \startbuffer
+%D \tfd Hi \bf there\sl, here \tfb I \bf am
+%D \stopbuffer
+%D
+%S \startsmaller
+%D \typebuffer
+%S \stopsmaller
+%D
+%D therefore becomes:
+%D
+%D \startvoorbeeld
+%D \haalbuffer
+%D \stopvoorbeeld
+%D
+%D Maybe this mechanism isn't always as logic, but as said
+%D before, we tried to make it as intuitive as possible.
+%D
+%D So a specific kind of glyph can be characterized by:
+%D
+%D \startsmaller
+%D family (cmr) + corps (12pt) + style (rm) + alternative (bf) + size (a)
+%D \stopsmaller
+%D
+%D The last component (the size) is optional.
+%D
+%D We introduced \type{\tf} as command to call for the current
+%D normally sized typeface. This commands results in roman,
+%D sans serif, teletype or whatever style is in charge. Such
+%D rather massive switches of style sometimes take more
+%D processing time than comfortable. Of course there is a
+%D workaround for this: we can call fonts directly by means of
+%D commands like:
+%D
+%D \starttypen
+%D \rmtf \sssl \tttf \rmbsa
+%D \stoptypen
+%D
+%D One should realize that this fast calls have limitations,
+%D they lack for instance automatic super- and subscript
+%D support.
+%D
+%D This leaves us two more commands: \type{\tx} and
+%D \type{\txx}. These activate a smaller and even more smaller
+%D font than the current one and adapt themselves to the
+%D current alternative, so when \type{\bf} is active,
+%D \type{\tx} gives a smaller boldface, which in turn can be
+%D called directly by \type{\bfx}.
+%D
+%D These two smaller alternatives are specified by the corps
+%D environment and therefore not necessarily have similar sizes
+%D as \type{\scriptsize} and \type{\scriptscriptsize}. The main
+%D reason for this incompatibility (which can easily be undone)
+%D lays in the fact that we often want a bit bigger characters
+%D than in math mode. In \CONTEXT\ for instance the \type{\tx}
+%D and \type{\txx} commands are used for surrogate
+%D \kap{smallcaps} which support both nesting and alternatives,
+%D like in {\bf\kap{a \kap{small} world}}, which was typeset by
+%D
+%D \starttypen
+%D \bf\kap{a \kap{small} world}
+%D \stoptypen
+%D
+%D And compare $\rm \scriptstyle THIS$ with the slightly larger
+%D \kap{THIS}: \ruledhbox{$\rm \scriptstyle\ scriptstyle THIS$}
+%D or \ruledhbox{\kap{THIS x style}} makes a big difference.

+%D Math fonts are a species in their own. They are tightly
+%D hooked into smaller and even smaller ones of similar breed
+%D to form a tight family. Let's first see how these are
+%D related:
+%D
+%D \startbuffer
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+ \bi x^2 =\rm 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+{\bi x^2}=\rm 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+ \bi x^2 =\tf 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+{\bi x^2}=\tf 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+ \bi x^2 =\bf 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+{\bi x^2}=\bf 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+ \bi x^2 =\sl 6x^2$
+%D $\tf x^2+\bf x^2+\sl x^2+\it x^2+\bs x^2+{\bi x^2}=\sl 6x^2$
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Gives both an expected and unexpected result:
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D We see here that the character shapes change accordingly to
+%D the current family, but that the symbols are always typeset
+%D in the font assigned to \type{\fam0}.
+%D
+%D \startbuffer
+%D $\tf\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D $\bf\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D $\sl\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D $\bs\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D $\it\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D $\bi\mf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = 6x^2$
+%D \stopbuffer
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D In this example we see a new command \type{\mf} surface
+%D which means as much as {\em math font}. This commands
+%D reactivates the last font alternative and therefore equals
+%D \type{\bf}, \type{\sl} etc. but by default it equals
+%D \type{\tf}:
+
+\def\mf{\tf}
+
+%D The previous example was typeset saying:
+%D
+%D \typebuffer
+%D
+%D Beware: the exact location of \type{\mf} is not that
+%D important, we could as well has said
+%D
+%D \startbuffer
+%D $\bf x^2 + x^2 + x^2 + x^2 + x^2 + x^2 = \mf 6x^2$
+%D \stopbuffer
+%D
+%D This is due to the way \TEX\ handles fonts in math mode.
+%D
+%D Of course we'll have to redefine \type{\mf} every time we
+%D change the current \type{\fam}.
+
+%D \macros
+%D {mbox,enablembox,mathop}
+%D
+%D Now how can we put this to use? Will the next sequence
+%D give the desired result?
+%D
+%D \startbuffer
+%D $\bf x^2 + \hbox{\mf whatever} + \sin(2x)$
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D It won't!
+%D
+%D \startvoorbeeld
+%D \let\mathop=\normalmathop \haalbuffer
+%D \stopvoorbeeld
+%D
+%D The reason for this is that \type{\sin} is defined as:
+%D
+%D \starttypen
+%D \def\sin{\mathop{\rm sin}\nolimits}
+%D \stoptypen
+%D
+%D We can fix this by defining
+
+\let\normalmathop=\mathop
+
+\def\mathop%
+ {\normalmathop
+ \bgroup
+ \let\rm=\mf
+ \let\next=}
+
+%D Of course this can be fixed, if not by a very dirty trick:
+%D redefining the \TEX\ primitive \type{\hbox}:
+%D
+%D \starttypen
+%D \let\normalhbox=\hbox
+%D
+%D \def\hbox%
+%D {\ifmmode\mbox\else\normalhbox\fi}
+%D \stoptypen
+%D
+%D With
+%D
+%D \starttypen
+%D \def\mbox#1#%
+%D {\normalhbox#1\bgroup\mf\let\next=}
+%D \stoptypen
+%D
+%D or more robust, that is, also accepting \type{\hbox\bgroup}:
+%D
+%D \starttypen
+%D \def\mbox%
+%D {\normalhbox\bgroup\mf
+%D \dowithnextbox{\box\nextbox\egroup}%
+%D \normalhbox}
+%D \stoptypen
+%D
+%D And now:
+%D
+%D \startbuffer
+%D $\bf x^2 + \hbox{whatever} + \sin(2x)$
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Indeed gives:
+%D
+%D \startvoorbeeld
+%D \enablembox\haalbuffer
+%D \stopvoorbeeld
+%D
+%D But, do we want this kind of trickery to be activated? No,
+%D simply because we cannot be sure of incompatibilties,
+%D although for instance unboxing goes ok. Therefore we
+%D introduce:
+
+\def\normalmbox%
+ {\normalhbox\bgroup\mf
+ \dowithnextbox{\box\nextbox\egroup}\normalhbox}
+
+\def\mbox%
+ {\ifmmode\normalmbox\else\normalhbox\fi}
+
+\def\enablembox%
+ {\appendtoks
+ \let\normalhbox=\hbox
+ \let\hbox=\mbox
+ \to\everymath}
+
+%D So in fact one can enable feature if needed. I would say:
+%D go along, but use grouping if needed!
+
+%D \macros
+%D {mrfam,mifam,syfam,exfam,
+%D bsfam,bifam,scfam,tffam,
+%D mafam,mbfam,msfam}
+%D
+%D After this short mathematical excursion, we enter the world
+%D of fonts and fontswitching. We start with something very
+%D \TEX: \type{\fam} specified font families. \TEX\ uses
+%D families for managing fonts in math mode. Such a family has
+%D three members: text, script and scriptscript: $x^{y^z}$. In
+%D \CONTEXT\ we take a bit different approach than \PLAIN\
+%D \TEX\ does. \PLAIN\ \TEX\ needs at least four families for
+%D typesetting math. We use those but give them symbolic names.
+
+\def\mrfam{0} % 0 (Plain TeX) Math Roman
+\def\mifam{1} % 1 (Plain TeX) Math Italic
+\def\syfam{2} % 2 (Plain TeX) Math Symbol
+\def\exfam{3} % 3 (Plain TeX) Math Extra
+
+%D \PLAIN\ \TEX\ also defines families for {\it italic}, {\sl
+%D slanted} and {\bf bold} typefaces, so we don't have to
+%D define them here.
+%D
+%D \starttypen
+%D \itfam % 4 (Plain TeX) Italic
+%D \slfam % 5 (Plain TeX) Slanted
+%D \bffam % 6 (Plain TeX) Boldface
+%D \stoptypen
+%D
+%D Family~7 in \PLAIN\ \TEX\ is not used in \CONTEXT, because
+%D we do massive switches from roman to sans serif, teletype or
+%D other faces.
+%D
+%D \starttypen
+%D \ttfam % 7 (Plain TeX) can be reused!
+%D \stoptypen
+%D
+%D We define ourselves some more families for {\bs bold
+%D slanted}, {\bi bold italic} and {\sc Small Caps}, so
+%D we can use them in math mode too. Instead of separate
+%D families for {\ss sans serif} and \type{teletype} we use the
+%D more general \type{\tffam}, which stands for typeface.
+
+\newfam\bsfam % 8 (ConTeXt) BoldSlanted
+\newfam\bifam % 9 (ConTeXt) BoldItalic
+\newfam\scfam % A (ConTeXt) SmallCaps
+\newfam\tffam % B (ConTeXt) TypeFace
+
+%D Normally \type{\mrfam} equals \type{\tffam}, but a more
+%D distinctive alternatives are possible, for instance the
+%D Euler and Concrete Typefaces.
+%D
+%D After having defined all those in nature non||mathematical
+%D families, we define ourselves some real math ones. These are
+%D needed for the \AMS\ Symbol Fonts and Extended Lucida
+%D Bright.
+
+\newfam\mafam % C (ConTeXt) Math A Fam (AmsTeX A)
+\newfam\mbfam % D (ConTeXt) Math B Fam (AmsTeX B)
+\newfam\mcfam % E (ConTeXt) Math C Fam
+
+%D Because there are 16~families and because \type{\ttfam}
+%D isn't used, at the moment we have two families left:~7
+%D and~F.
+%D
+%D To ease the support of font packages, we als define
+%D shortcuts to these familynames. This is necessary because
+%D the family names are in fact \type{\chardef}'s, which means
+%D that we're dealing with numbers (one can check this by
+%D applying \type{\showthe} and \type{\show}). In the
+%D specification of math symbols however we need hexadecimal
+%D numbers, so we have to convert the \type{\fam}'s value.
+
+\def\hexnumber#1%
+ {\ifcase#1
+ 0\or1\or2\or3\or4\or5\or6\or7\or8\or9\or A\or B\or C\or D\or E\or F%
+ \fi}
+
+\edef\hexmrfam {\hexnumber\mrfam} \edef\hexbsfam {\hexnumber\bsfam}
+\edef\hexmifam {\hexnumber\mifam} \edef\hexbifam {\hexnumber\bifam}
+\edef\hexsyfam {\hexnumber\syfam} \edef\hexscfam {\hexnumber\scfam}
+\edef\hexexfam {\hexnumber\exfam} \edef\hextffam {\hexnumber\tffam}
+\edef\hexitfam {\hexnumber\itfam} \edef\hexmafam {\hexnumber\mafam}
+\edef\hexslfam {\hexnumber\slfam} \edef\hexmbfam {\hexnumber\mbfam}
+\edef\hexbffam {\hexnumber\bffam} \edef\hexmcfam {\hexnumber\mcfam}
+
+%D We define some (very private) constants to improve speed,
+%D memory usage and consistency.
+
+\def\@plain@ {@f@pl@} % plain TeX encoding vector
+\def\@size@ {@f@si@} % corps size prefix (12pt etc)
+\def\@style@ {@f@st@} % full style prefix (roman etc)
+\def\@shortstyle@ {@f@sh@} % short style prefix (rm etc)
+\def\@letter@ {@f@le@} % first alternative typeface
+\def\@noletter@ {@f@no@} % second alternative typeface
+
+%D We also define a list of all text (i.e.\ non math symbol)
+%D families. I considered using something like:
+%D
+%D \starttypen
+%D \def\familylist%
+%D {\do\c!tf\do\c!sl\do\c!it\do\c!bf\do\c!bs\do\c!bi\do\c!sc}
+%D \stoptypen
+%D
+%D By assigning \type{\do} some suitable meaning one can
+%D process such lists quite fast. The current implementation
+%D uses the commalist processing macros and is not that
+%D slow either.
+
+\def\familylist%
+ {\c!tf,\c!sl,\c!it,\c!bf,\c!bs,\c!bi,\c!sc}
+
+%D All used styles, like rm, ss and tt, are saved in a comma
+%D separated list. Appart from practical limitations one can
+%D define as many styles as needed, but first we
+
+\let\stylelist=\empty
+
+%D Further on we have to take some precautions when dealing
+%D with special characters like~\type{~}, \type{_}
+%D and~\type{^}, so let us define ourselve some handy macros
+%D first.
+
+\def\protectfontcharacters%
+ {\catcode`\~=\@@letter
+ \catcode`\_=\@@letter
+ \catcode`\^=\@@letter\relax}
+
+\def\unprotectfontcharacters%
+ {\catcode`\~=\@@active
+ \catcode`\_=\@@subscript
+ \catcode`\^=\@@superscript\relax}
+
+%D The completeness of the Computer Modern Roman typefaces
+%D makes clear how incomplete other faces are. To honour 7~bit
+%D \ASCII, these fonts were designed using only the first 127
+%D values of the 256 ones that can be presented by one byte.
+%D Nowadays 8~bit character codings are more common, mainly
+%D because they permit us to predefine some composed
+%D characters, which are needed in most european languages.
+%D
+%D Supporting more than the standard \TEX\ encoding vector
+%D |<|which in itself is far from standard and differs per
+%D font|>| puts a burden on the fonts mechanism. The \CONTEXT\
+%D mechanism is far from complete, but can handle several
+%D schemes at once. The main problem lays in the accented
+%D characters and ligatures like~ff, although handling
+%D ligatures is not the responsibility of this module.
+%D
+%D By default, we use \PLAIN\ \TEX's approach of placing
+%D accents. All other schemes sooner or later give problems
+%D when we distribute \DVI||files are distributed across
+%D machines and platforms. Nevertheless, we have to take care
+%D of different encoding vectors, which tell us where to find
+%D the characters we need. This means that all kind of
+%D character placement macro's like \type{\"} and \type{\ae}
+%D have to be implemented and adapted in a way that suits
+%D these vectors.
+%D
+%D The main difference between different vector is the way
+%D accents are ordered and/or the availability of prebuilt
+%D accented characters. Accented characters can for instance be
+%D called for by sequences like \type{\"e}. Here the \type{\"}
+%D is defined as:
+%D
+%D \starttypen
+%D \def\"#1{{\accent"7F #1}}
+%D \stoptypen
+%D
+%D This macro places the accent \accent"7F {} on top of an~e
+%D gives \"e. Some fonts however can have prebuild accents and
+%D use a more direct approach like
+%D
+%D \starttypen
+%D \def\"#1{\if#1e\char 235\else ... \fi}
+%D \stoptypen
+%D
+%D The latter approach is not used in \CONTEXT, because we
+%D store relevant combinations of accents and characters in
+%D individual macros.
+
+%D We define character substitutes and commands with definition
+%D commands like:
+%D
+%D \starttypen
+%D \startcoding[texnansi]
+%D
+%D \defineaccent " a 228
+%D \defineaccent ^ e 234
+%D \defineaccent ' {\dotlessi} 237
+%D
+%D \definecharacter ae 230
+%D \definecharacter oe 156
+%D
+%D \definecommand b \newansib
+%D \definecommand c \newansic
+%D
+%D \stopcoding
+%D \stoptypen
+%D
+%D The last argument of \type{\defineaccent} and
+%D \type{\definecharacter} tells \TEX\ the position of the
+%D accented character in the encoding vector. In order to
+%D complish this, we tag each implementation with the character
+%D coding identifier. We therefore need two auxiliary variables
+%D \type{\charactercoding} and \type{\nocharactercoding}. These
+%D contain the current and default encoding vectors and both
+%D default to the \PLAIN\ one.
+
+\let\charactercoding = \@plain@
+\let\nocharactercoding = \@plain@
+
+%D \macros
+%D {startcoding}
+%D
+%D Before we can redefine accents and special characters, we
+%D have to tell \CONTEXT\ what encoding is in force. The next
+%D command is responsible for doing this and also takes care of
+%D the definition of the recoding commands.
+
+\def\startcoding[#1]%
+ {\protectfontcharacters
+ \showmessage{\m!fonts}{1}{#1}%
+ \def\charactercoding{@#1@}}
+
+\def\stopcoding%
+ {\let\charactercoding=\@plain@
+ \unprotectfontcharacters}
+
+%D \macros
+%D {defineaccent, definecharacter, definecommand}
+%D
+%D The actual definition of accents, special characters and
+%D commands is done with the next three commands.
+
+\def\defineaccent#1 #2 #3 %
+ {\setvalue{\charactercoding#1\string#2}{\char#3}}%
+
+\def\definecommand#1 #2 %
+ {\setvalue{\charactercoding\string#1}{#2}}
+
+\def\definecharacter#1 #2 %
+ {\setvalue{\charactercoding\string#1}{\char#2}}
+
+%D Here we see that redefining accents is characters is more
+%D or less the same as redefining commands. We also could have
+%D said:
+%D
+%D \starttypen
+%D \def\defineaccent#1 #2 {\definecommand#1\string#2 \char}
+%D \def\definecharacter#1 {\definecommand#1 \char}
+%D \stoptypen
+
+%D \macros
+%D {redefineaccent}
+%D
+%D Telling \CONTEXT\ how to treat accents and special
+%D characters is a two stage process. First we signal the
+%D system which commands are to be adapted, after which we can
+%D redefine their behavior when needed. We showed this in the
+%D previous paragraphs. These redefinitions are grouped at the
+%D end of this file, but we show some examples here.
+%D
+%D Accents or accent generating commands are redefined by:
+%D
+%D \starttypen
+%D \redefineaccent ' % grave
+%D \redefineaccent " % dieresis
+%D \redefineaccent ^ % circumflex
+%D \redefineaccent v % caron
+%D \stoptypen
+%D
+%D The original \PLAIN\ \TEX\ meaning of each accent generating
+%D command is saved first. Next these commands are redefined to
+%D do an indirect call to a macro that acts according to the
+%D encoding vector in use.
+
+\def\redefineaccent%
+ {\protectfontcharacters
+ \doredefineaccent}
+
+\def\doredefineaccent#1 %
+ {\def\!!stringa{\nocharactercoding\string#1}%
+ \@EA\letvalue\@EA\!!stringa\@EA=\csname\string#1\endcsname
+ \setvalue{\string#1}{\dohandleaccent#1}%
+ \unprotectfontcharacters}
+
+%D The next (in fact three) macros to take care of \type{\"e}
+%D as well as \type{\"{e}} situations. The latter one is always
+%D handled by \TEX's \type{\accent} primitive, but the former
+%D one can put the accents on top of characters as well as use
+%D \type{\char} to call for a character directly.
+
+\unexpanded\def\dohandleaccent#1%
+ {\def\dodohandleaccent%
+ {\ifx\next\bgroup
+ \def\next{\getvalue{\nocharactercoding#1}}%
+ \else
+ \def\next{\dododohandleaccent#1}%
+ \fi
+ \next}%
+ \futurelet\next\dodohandleaccent}
+
+\def\dododohandleaccent#1#2%
+ {\bgroup
+ \ifundefined{\charactercoding#1\string#2}%
+ \def\\{\getvalue{\nocharactercoding#1}#2\egroup}%
+ \else
+ \def\\{\getvalue{\charactercoding#1\string#2}\egroup}%
+ \fi
+ \\}
+
+%D The trick with \type{\\} is needed to prevent spaces from
+%D being gobbled after the accented character, should we have
+%D \type{\next}, we should have ended up with gobbled spaces.
+
+%D \macros
+%D {redefinecommand}
+%D
+%D Redefinition of encoding dependant commands like \type{\b}
+%D and \type{\c} can be triggered by:
+%D
+%D \starttypen
+%D \redefinecommand b % something math
+%D \redefinecommand c % something math
+%D \stoptypen
+%D
+%D Handling of characters is easier than handling accents
+%D because here we don't have to take care of arguments. We
+%D just call for the right glyph in the right place.
+%D
+%D The \type{\next} construction permits handling of commands
+%D that take arguments. This means that we can use this
+%D command to redefine accent handling commands too.
+
+\def\redefinecommand#1 %
+ {\def\!!stringa{\nocharactercoding#1}%
+ \@EA\letvalue\@EA\!!stringa\@EA=\csname#1\endcsname
+ \setvalue{#1}{\dohandlecommand{#1}}}%
+
+\unexpanded\def\dohandlecommand#1%
+ {\doifdefinedelse{\charactercoding#1}
+ {\def\next{\getvalue{\charactercoding#1}}}
+ {\def\next{\getvalue{\nocharactercoding#1}}}%
+ \next}
+
+%D \macros
+%D {redefinecharacter}
+%D
+%D Special characters, which differ from accented characters
+%D in that they are to be presented as they are, are redefined
+%D by
+%D
+%D \starttypen
+%D \redefinecharacter ae % ae
+%D \redefinecharacter cc % ccedilla
+%D \stoptypen
+%D
+%D To keep things simple, we just copy this command:
+
+\let\redefinecharacter=\redefinecommand
+
+%D \macros
+%D {magfactor,magfactorhalf}
+%D
+%D There are several ways to specify a font. Three of them are
+%D pure \TeX\ ones, the fourth one is new:
+%D
+%D \starttypen
+%D \font\name=cmr12
+%D \font\name=cmr12 at 10pt
+%D \font\name=cmr12 scaled \magstep2
+%D \font\name=cmr12 sa 1.440
+%D \stoptypen
+%D
+%D The non||\TEX\ alternative \type{sa} stands for {\em scaled
+%D at}. This means as much as: scale the corpssize with this
+%D factor. The value 1.440 in this example is derived
+%D from the \type{\magstep}'s as mentioned in
+%D \in{table}[tab:magstep]. We therefore introduce
+%D \type{\magfactor} as an alternative for \type{\magstep}.
+%D
+%D \plaatstabel[hier][tab:magstep]
+%D {Factors to be used with \type{sa.}}
+%D \starttabel[|c|c|c|]
+%D \HL
+%D \NC \bf magstep \NC \bf equivalent \NC \bf factor \NC\SR

+%D \HL
+%D \stoptabel
+
+\def\magfactor#1%
+ {\ifcase#1 1.000\or 1.200\or 1.440\or 1.728\or 2.074\or 2.488\or 1\fi}
+
+\def\magfactorhalf%
+ {1.095}
+
+%D These macros enable the use of definitions like \type{sa
+%D \magfactor3} which saves us both (mis|)|calculations and
+%D potential mistypings.
+%D
+%D Because \type{sa} is not a \TEX\ supported alternative, we
+%D have to test for it ourselves. In doing so, we need an
+%D auxiliary \DIMENSION. We cannot use \type{\scratchdimen}
+%D because font loading can happen at any moment due to
+%D postponed loading. We could instead have used dirty grouping
+%D tricks, but this one works too.
+
+\newdimen\scaledfont
+
+\def\docalculatefont#1 sa #2sa#3*#4*#5*% The spaces are needed!
+ {\edef\fontscale{#2}%
+ \ifx\fontscale\empty
+ \expandafter\font\csname#4#5\endcsname=#1\relax
+ \else
+ \scaledfont=#4\relax
+ \expandafter\font\csname#4#5\endcsname=#1 at \fontscale\scaledfont\relax
+ \fi}
+
+%D I considered checking for mistakenly use of \PLAIN's
+%D \type{\magstep}'s but although it would take only a few
+%D lines of code, this would not add to consistent use. I
+%D therefore removed this check.
+
+\def\dodoloadfont#1#2#3%
+ {\expanded{\docalculatefont\getvalue{\??ft#1#2} sa sa*#1*#2*}%
+ #3\relax
+ \getvalue{#1#2}}
+
+%D A more ugly but correct alternative for this is:
+%D
+%D \starttypen
+%D \def\docalculatefont#1sa #2sa#3*#4*#5*%
+%D {\edef\fontscale{#2}%
+%D \scaledfont=#4\relax
+%D \expandafter\font\csname#4#5\endcsname=#1
+%D \ifx\fontscale\empty\else at \fontscale\scaledfont\fi}
+%D \stoptypen
+%D
+%D This one saves a few bytes of memory, but is not particular
+%D faster due to the often unneeded assignment.
+
+%D The loading macro is used in two macros. One of them takes
+%D care of fixed width teletype fonts.
+
+\def\doloadfont#1#2%
+ {\debuggerinfo{\m!fonts}{loaded #1#2}%
+ \dodoloadfont{#1}{#2}{}}
+
+\def\doloadttfont#1#2%
+ {\debuggerinfo{\m!fonts}{loaded fixed #1#2}%
+ \dodoloadfont{#1}{#2}{\expandafter\hyphenchar\csname#1#2\endcsname=-1}}
+
+%D \macros
+%D {getfontname}
+%D
+%D The names of the fonts can be called with the rather simple
+%D macro \type{\getfontname}. When for instance we pass
+%D \type{12ptrmtf} as argument, we get \getfontname{12ptrmtf}.
+
+\def\getfontname#1%
+ {\getvalue{\??ft#1}}
+
+%D Now we enter the area of font switching. The switching
+%D mechanism has to take care of several situations, like:
+%D
+%D \startopsomming[opelkaar]
+%D \som changing the overal document fonts (including margins,
+%D headers and footers)
+%D \som changing local fonts (only the running text)
+%D \som smaller and even more smaller alternatives (super-
+%D and subscripts)
+%D \stopopsomming
+%D
+%D \TEX\ offers a powerfull family mechanism for super- and
+%D subscripts in math mode. In text mode however, we don't use
+%D families for the smaller alternatives, and therefore have
+%D to take care of it otherwise.
+
+%D \macros
+%D {definecorpsenvironment}
+%D
+%D The relationship between the several sizes of a font, is
+%D defined by:
+%D
+%D \showsetup{\y!definecorpsenvironment}
+%D
+%D Later on we will see how these parameters are used, so for
+%D the moment we stick with an example:
+%D
+%D \starttypen
+%D \definecorpsenvironment
+%D [12pt]
+%D [ text=12pt,
+%D script=9pt,
+%D scriptscript=7pt,
+%D x=10pt,
+%D xx=8pt,
+%D big=12pt,
+%D small=10pt]
+%D \stoptypen
+%D
+%D The first argument specifies the corps size to which the
+%D settings apply. All second parameters are specified in
+%D dimensions and tell us more about related sizes.
+%D
+%D Due to the fact that \type{\c!text} and \type{\s!text} can
+%D have a similar meaning, and therefore can lead to an
+%D unwanted loop, we temporary redefine \type{\c!text}. For
+%D the moment this in only place that some trickery is needed
+%D to fool the multilingual interface.
+
+\def\definecorpsenvironment%
+ {\dodoubleempty\dodefinecorpsenvironment}
+
+\def\dodefinecorpsenvironment[#1][#2]%
+ {\let\c!savedtext=\c!text
+ \let\c!text=\s!text
+ \doifundefined{\??ft#1\s!text}

+ \getparameters[\??ft#1][#2]%
+ \let\c!text=\c!savedtext
+ \setvalue{\@size@#1}{\docompletefontswitch[#1]}}
+
+%D We default all parameters to the main corps size (begin
+%D \type{#1}), so the next setup is valid too:
+%D
+%D \starttypen
+%D \definecorpsenvironment[24pt]
+%D \stoptypen
+%D
+%D All parameters can be redefined when needed, so one does
+%D not have to stick to the default ones.
+
+%D \macros
+%D {definecorps}
+%D
+%D The next step in defining a corps involves the actual font
+%D files, which can be recognized by their extension
+%D \type{tfm}. Installing those file is often beyond the
+%D scope of the user and up to the system administrator.
+%D
+%D \showsetup{\y!definecorps}
+%D
+%D This commands takes three arguments, where \showparameter\
+%D takes a (series of) corps size(s) and \showparameter\
+%D the style group to which the definitions belong.
+%D
+%D Argument \showparameter\ accepts any suitable alternative,
+%D as specified by the \TEX\ families, extended with a, b and
+%D higher sizes or the normal \TEX\ mathematical families and
+%D some more.
+%D
+%D We show two examples, that show all the alternative
+%D scaling options. The \type{\tfa} alternatives can be
+%D extended with \type{\bfa}, \type{\slb}, etc. or even
+%D \type{e} and higher alternatives.
+%D
+%D \starttypen
+%D \definecorps [12pt] [rm]
+%D [tf=cmr12,
+%D bf=cmbx12,
+%D it=cmti12,
+%D sl=cmsl12,
+%D bi=cmbxti10 at 12pt,
+%D bs=cmbxsl10 at 12pt,
+%D tfa=cmr12 scaled \magstep1,
+%D tfb=cmr12 scaled \magstep2,
+%D tfc=cmr12 scaled \magstep3,
+%D tfd=cmr12 scaled \magstep4,
+%D sc=cmcsc10 at 12pt]
+%D
+%D \definecorps [12pt,11pt,10pt,9pt,8pt] [rm]
+%D [tf=lbr sa 1,
+%D bf=lbd sa 1,
+%D it=lbi sa 1,
+%D sl=lbsl sa 1,
+%D bi=lbdi sa 1,
+%D bs=lbdi sa 1,
+%D tfa=lbr sa 1.200,
+%D tfb=lbr sa 1.440,
+%D tfc=lbr sa 1.728,
+%D tfd=lbr sa 2.074,
+%D sc=lbr sa 0.833]
+%D \stoptypen
+%D
+%D The second example shows that we can define more sizes at
+%D once. The main difference between these examples is that the
+%D Computer Modern Roman come in many design sizes. This means
+%D that there we cannot define them in bulk using \type{sa}.
+%D Instead of \type{rm} (roman) one can define \type{ss} (sans
+%D serif), \type{tt} (teletype), \type{hw} (hand written),
+%D \type{cg} (calygraphic) and whatever styles.
+
+\def\definecorps%
+ {\dotripleargument\dodefinecorps}
+
+%D The first argument may be a comma separated list. This,
+%D combined with specifications using \type{sa} can save a lot
+%D of typing. Although all arguments should be specified, we
+%D treat the second argument as optional.
+

+%D Defining a corps involves two actions: defining the specific
+%D style related alternatives, like \type{\rma}, \type{\bfa}
+%D and \type{\rmsla}, and storing the definitions of their
+%D corps size related fonts. The first step is corps
+%D independant but executed every time. This permits user
+%D definitions like \type{\tfw} or \type{\bfq} for real large
+%D alterbatives.

+%D These macros show that quite some definitions take place.
+%D Fonts are not loeaded yet! This means that at format
+%D generation time, no font files are preloaded.
+%D
+%D We could have use \type{\unexpanded\setvalue} instead of
+%D the \type{\donottest} prefixes. However, this would lead to
+%D about 400 extra entries in the hash table.
+%D
+%D We can save ourselved some 400 csnames by packing the name
+%D and the encoding. But ..... not done yet .....
+
+%D \macros
+%D {everycorps,EveryCorps}
+%D
+%D Every change in corps size has conseqences for the baseline
+%D distance and skips between paragraphs. These are initialized
+%D in other modules. Here we only provide the hooks that
+%D garantees their handling.
+
+\newevery \everycorps \EveryCorps
+
+%D At the system level one can initialize thing like:
+%D
+%D \starttypen
+%D \appendtoks \setupspacing \to \everycorps
+%D \stoptypen
+%D
+%D While users can add their own non standard commands like:
+%D
+%D \starttypen
+%D \EveryCorps{\message{changing to corps \the\corpssize}}
+%D \stoptypen
+%D
+%D Personnaly I never felt the need for such extensions, but
+%D at least its possible.
+
+%D \macros
+%D {globalcorpssize,localcorpssize}
+%D
+%D Next we'll do the tough job of font switching. Here we
+%D have to distinguish between the global (overal) corps size
+%D and the local (sometimes in the textflow) size. We store
+%D these dimensions in two \DIMENSION\ registers.
+
+\newdimen\globalcorpssize \globalcorpssize=12pt
+\newdimen\localcorpssize \localcorpssize =\globalcorpssize
+
+%D \macros
+%D {corpssize}
+%D
+%D These two registers are not to be misused in calculations.
+%D For this purpose we keep a copy:
+
+\newdimen\corpssize \corpssize=\globalcorpssize
+
+%D \macros
+%D {outputresolution}
+%D
+%D Sometimes (to be honest: not in this module) we need to
+%D take the system resolution into account. Therefore we also
+%D define a macro:
+
+\def\outputresolution {300}
+
+%D \macros
+%D {corpsfactor,corpspoints}
+%D
+%D For multiplication purposes we keep an auxiliary counter
+%D and macro (here the expansion is not explicitly needed):
+
+\newcount\corpspoints \dimensiontocount\corpssize\corpspoints
+
+\edef\corpsfactor{\withoutpt\the\corpssize}
+
+%D When we assign for instance 12pt to a \DIMENSION\ register
+%D the \type{\the}'d value comes out as 12.0pt, which is
+%D often not the way users specifies the corps size. Therefore
+%D we also store normalized value.
+
+\def\normalizecorpssize#1\to#2%

+\def\korpspunten {\corpspoints}
+
+%D some day.
+
+%D \macros
+%D {fontsize,fontstyle}
+%D
+%D Within a corps, fonts can come in different sizes. For
+%D instance \type{\tf} is accompanied by \type{\tfa},
+%D \type{\tfb} etc. The third character in these sequences
+%D represents the size. The actual size is saved in a macro
+
+\let\fontsize = \empty
+
+%D The style, being roman (\type{\rm}), sans serif (\type{\ss})
+%D etc. is also available in a macro in \type{rm}, \type{ss}
+%D etc. form:
+
+\let\fontstyle = \empty
+
+%D All things related to fonts are grouped into files with
+%D names like \expandafter\type\expandafter{\f!fontprefix cmr}.
+%D These files are loaded by:
+
+\def\doreadfontdefinitionfile#1%
+ {\doifundefined{\c!file\f!fontprefix#1}%
+ {\setvalue{\c!file\f!fontprefix#1}{}%
+ \edef\saveddqcatcode{\the\catcode`"}%
+ \catcode`\"=\@@other
+ \readsysfile{\f!fontprefix#1}
+ {\showmessage{\m!fonts}{2}{#1}}
+ {\showmessage{\m!fonts}{3}{#1}}%
+ \catcode`\"=\saveddqcatcode}}
+
+%D Such files are only loaded once! This permits redundant
+%D loading, but at the same time forced grouping when we want
+%D continuously mix all kind of font, which of course is a kind
+%D of typographically sin. The \type{"} is made inactibe if
+%D needed to prevent problems with loading files that use this
+%D character in numbers.

+
+%D \TEX\ loads font metric files like \type{cmr10.tfm} and
+%D \type{tir.tfm} only once. In \PLAIN\ \TEX\ some font files
+%D are {\em preloaded}. This means that the font files are
+%D loaded, but not accessible yet by name. This is accomplished
+%D by saying:
+%D
+%D \starttypen
+%D \font\preloaded=cmr10 at 11pt
+%D \stoptypen
+%D
+%D and using the name \type{\preloaded} again and again, so
+%D fonts are indeed loaded, but unnamed, and therefore
+%D unaccessible. In \CONTEXT\ we don't preload fonts, not even
+%D the \PLAIN\ \TEX\ ones, although users can access them. Now
+%D why is this done?
+
+%D Defining fonts using \type{\definecorps} takes time, so we
+%D prefer to predefine at least the Computer Modern Roman
+%D fonts. However, loading all those fonts at definition time
+%D would take both time and space. But even worse, once fonts
+%D are loaded into memory, their encoding vector is fixed,
+%D which is a handicap when we want to distribute the compact
+%D \type{fmt} files. So what we want to do is defining fonts in
+%D a way that postpones the loading. We accomplish this by only
+%D loading the fonts when we switch to another corps size.
+%D Among the other alternatives, such as loading the font at
+%D the moment of activation and redefining the activation
+%D macro afterwards, this proved to be the most efficient
+%D alternative.
+%D
+%D The next few macros take care of the one exeption on this
+%D scheme. When at format generation time we load the default
+%D font file, the one that defines the Computer Modern Fonts,
+%D we don't want the fonts metrics to end up in the format
+%D file, so we temporary prohibit loading. This means that at
+%D runtime we have to load the default corps size just before
+%D we start typesetting.
+%D
+%D Therefore we have to signal the font switching macros that
+%D we are preloading fonts. As long as the next boolean is,
+%D true, no loading is done.
+
+\newif\ifloadingfonts \loadingfontstrue
+
+%D \macros
+%D {preloadfonts}
+%D
+%D Preloading is only called for once, during the startup
+%D sequence of a session. After the loading job is done, the
+%D macro relaxes itself and reset the signal.
+
+\def\preloadfonts%
+ {\showmessage{\m!fonts}{6}{\normalizedcorpssize\normalspace\fontstyle}%
+ \doswitchpoints[\normalizedcorpssize]%
+ \doswitchstyle[\fontstyle]%
+ \global\let\preloadfonts=\relax
+ \global\loadingfontsfalse}
+
+%D Here comes the main font switching macros. These macros
+%D handle changes in size as well as returning to the global
+%D corps size.
+
+\def\dosetfont[#1]%
+ {\doifelse{#1}{\v!globaal}
+ {\restoreglobalcorps}
+ {\processcommalist[#1]\dodosetfont

+ {#2\dosetsubstitutefont{#1}}}
+ {\doifdefinedelse{\@style@#1}
+ {\edef\fontstyle{#1}}
+ {\doreadfontdefinitionfile{#1}}}}
+
+%D When users specify for instance a 13 point corps while no
+%D such corps is defined, the system automatically tries to
+%D find a best fit, that is the nearest smaller defined
+%D corpszize. A smaller one is definitely better than a larger
+%D one, simply because otherwise a lot of overfull box messages
+%D are more probable to occur. By taking a value slightly
+%D smaller than half a point, we can use the next method.
+
+\def\dosetsubstitutefont#1%
+ {\scratchdimen=#1\relax
+ \advance\scratchdimen by .499pt
+ \dimensiontocount\scratchdimen\scratchcounter
+ \advance\scratchcounter by -1
+ \ifnum\scratchcounter>3
+ \dododosetfont{\the\scratchcounter pt}{}%
+ \fi}
+
+%D Next we're going to implement some switching macros we
+%D already used in when defining fonts. The first one takes
+%D care of the style and is used by commands like \type{\rma}.
+
+\def\switchtofontstyle#1#2%
+ {\getvalue{#1}%
+ \getvalue{\c!tf#2}}
+
+%D The second one is responsible for commands like \type{\bfa}
+%D and the third one handles the combined \type{\rmbfa}
+%D alternatives.
+
+\def\switchtofontalternative#1#2%
+ {\def\fontsize{#2}%
+ \setfontstyle{\fontstyle}{\fontstyle}%
+ \donottest\getvalue{#1}}
+
+\def\switchtofontstylealternative#1#2#3%
+ {\getvalue{\normalizedcorpssize#1#2#3}}
+
+%D Setting the normal sized as well as the x and xx smaller
+%D sizes is accomplished by the next set of macros. When in
+%D math mode, the commands \type{\tx} and \type{\txx} are
+%D just a switch to the script and double script styles, but
+%D in text mode the values defined by the corpsenvironment are
+%D used.
+
+\def\dosetsomextypeface#1%
+ {\doifdefinedelse{#1}
+ {\getvalue{#1}}
+ {\showmessage{\m!fonts}{7}{#1}}}%
+
+\def\dosetxtypeface#1%
+ {\ifmmode
+ \scriptstyle
+ \else
+ \dosetsomextypeface
+ {\getvalue{\??ft\normalizedcorpssize\c!x}% % pt
+ \getvalue{\@shortstyle@\fontstyle}% % rm
+ #1}% % tf
+ \unexpanded\def\tx{\dosetxxtypeface{#1}}%
+ \fi}
+
+\def\dosetxxtypeface#1%
+ {\ifmmode
+ \scriptscriptstyle
+ \else
+ \dosetsomextypeface
+ {\getvalue{\??ft\normalizedcorpssize\c!xx}% % pt
+ \getvalue{\@shortstyle@\fontstyle}% % rm
+ #1}% % tf
+ \let\tx=\relax
+ \let\txx=\relax
+ \fi}
+
+%D These macros also show us that when we call for \type{\tx},
+%D this macro is redefined to be \type{\txx}. Therefore calls
+%D like:
+%D
+%D \startbuffer
+%D {small \tx is \tx beautiful}
+%D {small \tx is \txx beautiful}
+%D {small \txx is \tx beautiful}
+%D {small \txx is \txx beautiful}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D result in:
+%D
+%D \startvoorbeeld
+%D \startregels
+%D \haalbuffer
+%D \stopregels
+%D \stopvoorbeeld
+%D
+%D Setting the main size involves the style list and therefore
+%D takes a bit more time. Keep in mind that the fontsize is
+%D represented by a character or empty.
+
+\def\settextfont#1%
+ {\def\dosettextfont##1%
+ {\doifdefinedelse{\textface#1##1\fontsize}
+ {\setvalue{#1##1}{\donottest\getvalue{\textface#1##1\fontsize}}}
+ {\setvalue{#1##1}{\donottest\getvalue{\textface#1##1}}}}%
+ \rawprocesscommalist[\familylist]\dosettextfont}
+
+\def\settextfonts%
+ {\rawprocesscommalist[\stylelist]\settextfont}
+
+%D All three sizes come together in the macro:
+
+\def\settypefaces#1#2%
+ {\setvalue{#2}%
+ {\donottest\dosettypeface{#1}{#2}}%
+ \setvalue{#2\c!x}%
+ {\donottest\dosetxtypeface{#2}}%
+ \setvalue{#2\c!xx}%
+ {\donottest\dosetxxtypeface{#2}}}%
+
+%D Earlier in this module we defined some \TEX\ families. Here
+%D we introduce the macros that are responsible for setting
+%D them. The first argument of the next macro takes the style
+%D in its short form (rm, ss, etc). The second argument is the
+%D alternative (tf, bf, etc).
+
+%D Before actually assigning the font to a family we activate
+%D it. This is needed because loading of fonts is postponed
+%D until the first time it's called for. This also forces us to
+%D set the text family after we've set the script ones, else
+%D the latter one would be in force after executing this macro.

+%D Setting the math families looks much like setting the texts\
+%D ones. This time however we use the 12 point font as a
+%D default when nothing is defined. This enables us to
+%D implement partial schemes. Here we also set the
+%D \type{\skewchar}, which takes care of accents in math mode
+%D (actually it's the largest accent). The first family needs a
+%D bit different treatment because it can be set to the default
+%D roman as well as a user defined font.

+%D Here we didn't define the 24 point corps environment, so
+%D it's defined automatically. Of course one can always use the
+%D \TEX\ primitive \type{\font} to switch to whatever font
+%D needed.
+
+%D When asking for a complete font switch, for instance from 10
+%D to 12~points, the next macro does the job. First we
+%D normalize the size, nect we define the current range of
+%D text, script and scriptscript sizes, then we set the text
+%D fonts and the math families and finally we activate the
+%D default typeface and also set the font specific parameters
+%D assigned to \type{\everycorps}

+%D \macros
+%D {setupcorps,switchtocorps}
+%D
+%D The next two macros are user ones. With \type{\setupcorps}
+%D one can set the document corps size, font family, style
+%D and/or options defined in files, for example:
+%D
+%D \starttypen
+%D \setupcorps[cmr,ams,12pt,roman]
+%D \stoptypen
+%D
+%D This command affects the document as a whole: text, headers
+%D and footers. The second macro however affects only the text:
+%D
+%D \starttypen
+%D \switchtocorps[10pt]
+%D \stoptypen
+%D
+%D So we've got:
+%D
+%D \showsetup{\y!setupcorps}
+%D \showsetup{\y!switchtocorps}
+%D
+%D Both macros look alike. The second one also has to take
+%D all kind of keywords into account.

+%D
+%D When we're typesetting at for instance 10pt, we can call for

+%D related to this main size, using \type{\switchtocorps[small]}.

+%D \macros
+%D {restoreglobalcorps}
+%D
+%D Users can set whatever font available while typesetting text.
+%D Pagenumnbers, footers, headers etc. however must be typeset
+%D in the main corps and style of the document. Returning to
+%D the global state can be done with the next macro:
+
+\def\restoreglobalcorps%
+ {\let\fontsize=\empty
+ \doswitchpoints[\normalizedglobalcorpsize]%
+ \doswitchstyle[\globalfontstyle]%
+ \redoconvertfont % just in case a pagebreak occurs
+ \tf}
+
+%D This macro has to be called when entering the pagebody
+%D handling routine as well as the footnote insert routine.
+%D Users can access this feature |<|for instance when one wants
+%D to typeset tables and alike in the main corps and style
+%D while the running text is temporary set to a smaller one|>|
+%D by saying \type{\switchtocorps[global]}.
+
+%D \macros
+%D {rasterfont}
+%D
+%D There are (at the moment) two situations in which we want to
+%D have fast access to a particular font. When we are using
+%D \TEX\ to typeset rasters, we use small {\rasterfont.}'s
+%D (a rather small period indeed), the same as \PICTEX\ uses
+%D for drawing purposes.
+
+\def\rasterfont%
+ {\getvalue{\!!fivepoint\c!rm\c!tf}}
+
+%D \macros
+%D {infofont}
+%D
+%D The second situation occurs when we enable the info mode,
+%D and put all kind of status information in the margin. We
+%D don't want huge switches to the main corps and style, so
+%D here too we use a direct method.
+
+\def\infofont%
+ {\getvalue{\!!sixpoint\c!tt\c!tf}%
+ \the\everycorps}
+
+%D \macros
+%D {definealternativestyle}
+%D
+%D In the main modules we are going to implement lots of
+%D parameterized commands and one of these parameters will
+%D concern the font to use. To suit consistent use of fonts we
+%D here implement a mechanism for defining the keywords that
+%D present a particular style or alternative.
+%D
+%D \starttypen
+%D \definealternativestyle [keywords] [\style] [\nostyle]
+%D \stoptypen
+%D
+%D The first command is used in the normal textflow, while the
+%D second command takes care of headings and alike. Consider
+%D the next two definitions:
+%D
+%D \starttypen
+%D \definealternativestyle [bold] [\bf] []
+%D \definealternativestyle [cap] [\kap] [\kap]
+%D \stoptypen
+%D
+%D A change \type{\bf} in a heading which is to be set in
+%D \type{\tfd} does not look that well, so therefore we leave
+%D the second argument of \type{\definealternativestyle} empty.
+%D When we capatalize characters using the pseudo small cap
+%D command \type{\kap}, we want this to take effect in both
+%D text and headings, which is accomplished by assigning both
+%D arguments.
+
+\def\dodefinealternativestyle[#1][#2][#3]%
+ {\def\docommando##1%
+ {\doifundefined{##1}
+ {\expandafter\ifx\csname##1\endcsname#2\else
+ \setvalue{##1}{\groupedcommand{#2}{}}%
+ \fi}%
+ \setvalue{\@letter@##1}{#2}%
+ \setvalue{\@noletter@##1}{#3}}%
+ \processcommalist[#1]\docommando}
+
+\def\definealternativestyle%
+ {\dotripleargument\dodefinealternativestyle}
+
+%D This command also defines the keyword as command. This means
+%D that the example definition of \type{bold} we gave before,
+%D results in a command \type{\bold} which can be used as:
+%D
+%D \startbuffer
+%D He's a \bold{man} man with a {\bold head}.
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D or
+%D
+%D \startvoorbeeld
+%D \definealternativestyle[bold][\bf][]\haalbuffer
+%D \stopvoorbeeld
+%D
+%D Such definitions are of course unwanted for \type{\kap}
+%D because this would result in an endless recursive call.
+%D Therefore we check on the existance of both the command and
+%D the substitution. The latter is needed because for instance
+%D \type{\type} is an entirely diferent command. That command
+%D handles verbatim, while the style command would just switch
+%D to teletype font. This is just an example of a tricky
+%D naming coincidence.
+
+%D \macros
+%D {doconvertfont,noconvertfont,
+%D dontconvertfont,redoconvertfont}
+%D
+%D After having defined such keywords, we can call for them by
+%D using
+%D
+%D \starttypen
+%D \doconvertfont{keyword}{text}
+%D \stoptypen
+%D
+%D We deliberately pass an argument. This enables us to
+%D assign converters that handle one agrument, like
+%D \type{\kap}.
+%D
+%D By default the first specification is used to set the style,
+%D exept when we say \type{\dontconvertfont}, after which the
+%D second specification is used. We can also directly call for
+%D \type{\noconvertfont}. In nested calls, we can restore the
+%D conversion by saying \type{\redoconvertfont}.
+
+\unexpanded\def\dodoconvertfont#1#2%
+ {\doifdefinedelse{\@letter@#1}
+ {\doifelsenothing{#1}
+ {\def\next{}}
+ {\def\next{\getvalue{\@letter@#1}}}}
+ {\doifdefinedelse{#1}
+ {\def\next{\getvalue{#1}}}
+ {\def\next{#1}}}%

+
+\unexpanded\def\redoconvertfont%
+ {\let\doconvertfont=\dodoconvertfont}
+
+%D These commands are not grouped! Grouping is most probably
+%D done by the calling macro's and would lead to unnecessary
+%D overhead.
+
+%D \macros
+%D {em,emphasistypeface,emphasisboldface}
+%D
+%D The next macro started as a copy of Donald Arseneau's
+%D \type{\em} (\TUGNEWS\ Vol.~3, no.~1, 1994). His
+%D implementation was a bit more sophisticated version of the
+%D standard \LATEX\ one. We furter enhanced the macro, so now
+%D it also adapts itself to boldface mode. Because we favor
+%D {\sl slanted} type over {\it italic}, we made the emphasis
+%D adaptable, for instance:
+%D
+%D \starttypen
+%D \def\emphasistypeface {\it}
+%D \def\emphasisboldface {\bi}
+%D \stoptypen
+%D
+%D But we prefer:
+
+\def\emphasistypeface {\sl}
+\def\emphasisboldface {\bs}
+
+\unexpanded\def\em%
+ {\ifnum\fam=\itfam
+ \def\emphasistypeface{\it}\tf
+ \else\ifnum\fam=\slfam
+ \def\emphasistypeface{\sl}\tf
+ \else\ifnum\fam=\bffam
+ \emphasisboldface
+ \else\ifnum\fam=\bsfam
+ \def\emphasisboldface{\bs}\bf

+ \else
+ \emphasistypeface
+ \fi\fi\fi\fi\fi
+ \ifdim\fontdimen1\font>\!!zeropoint
+ \expandafter\aftergroup
+ \fi
+ \emphasiscorrection}
+
+%D Donald's (adapted) macros take the next character into
+%D account when placing italic correction. As a bonus we also
+%D look for something that looks like a dash, in which case we
+%D don't correct.
+
+\def\emphasiscorrection%
+ {\ifhmode
+ \expandafter\emphasislook
+ \fi}
+
+\def\emphasislook%

+%D some punctuation is met. We also show how the mechanism
+%D adapts itself to bold, italic and slanted typing.

+%D \macros
+%D {setfont}
+%D
+%D Every now and then we want to define a font directly, for

+%D some typing:
+
+\def\setfont%
+ {\def\dosetfont%
+ {\nextfont\stelinterliniein}%
+ \afterassignment\dosetfont
+ \font\nextfont=}
+
+%D One can call this macro as:

+%D \setfont cmr10 at 60pt
+%D \stoptypen
+%D
+%D After which the font is active and the baselines and
+%D struts are set.

+%D By default we load the Computer Modern Roman fonts and
+%D activate the 12pt roman corps. Sans serif and teletype are
+%D also available and can be called for by \type{\ss} and
+%D \type{\tt}.
+
+%D We also load the high \ASCII\ waarde as defined by the
+%D standard \kap{IBM PC} codepage. Finaly we load the
+%D \POSTSCRIPT\ standard predefined accented characters
+%D encoding vector as provided by Y\&Y named \type{texnansi}.
+%D These are for instance used when we load Lucida Bright
+%D (\type{lbr}) or \POSTSCRIPT\ Times Roman (\type{ptr}),
+%D Helvetica (\type{phv}) and Courier (\type{pcr}) which are
+%D also available as whole (\type{\setupcorps[pos]}).

+%D The Lucida Bright fonts are both good looking and and

+%D When loading hyphenation patterns, \TEX\ assign a number to
+%D each loaded table, starting with~0. Switching to a specific
+%D table is done by assigning the relevant number to the
+%D predefined \COUNTER\ \type{\language}. Unfortunately the
+%D name of this command suits very well the name of the
+%D language switching command we are to define, so let's save
+%D this primitive under another name:
+
+\let\normallanguage = \language
+
+%D We keep track of the last loaded patterns by means of a
+%D pseudo \COUNTER. This just one of those situations in which
+%D we don't want to spent a real one.
+
+\newcounter\loadedlanguage
+
+%D \macros
+%D {currentlanguage}
+%D {}
+%D
+%D Instead of numbers,we are going to use symbolic names for
+%D the languages. The current langage is saved in the macro
+%D \type{\currentlanguage}.
+
+\let\currentlanguage = \empty
+
+%D \macros
+%D {installlanguage}
+%D {}
+%D
+%D Hyphenation patterns can only be loaded when the format file
+%D is prepared. The next macro takes care of this loading. A
+%D language is specified with
+%D
+%D \showsetup{\y!installlanguage}
+%D
+%D When \type{\c!status} equals \type{\v!start}, both patterns
+%D and additional hyphenation specifications are loaded. These
+%D files are seached for on the system path and are to be
+%D named:
+%D
+%D \starttypen
+%D \f!languageprefix-identifier.\f!patternsextension
+%D \f!languageprefix-identifier.\f!hyhensextension
+%D \stoptypen
+%D
+%D The \type{\c!spatiering} specifies how the spaces after
+%D punctuation has to be handled. English is by tradition more
+%D tolerant to inter||sentence spacing than other languages.
+%D
+%D This macro also defines \type{\identifier} as a shortcut
+%D switch to the language. Furthermore the command defined as
+%D being language specific, are executed. With
+%D \type{\c!default} we can default to another language
+%D (patterns) at format generation time. This default language
+%D is overruled when the appropriate patterns are loaded (some
+%D implementations support run time addition of patterns to a
+%D preloaded format).

+%D The values \type {\c!leftsentence} and \type

+%D automatic subsentence boundary glyphs, like in {\fr
+%D |<|french guillemots|>|} or {\de |<|german guillemots|>|} or
+%D {\nl |<|dutch dashes|>|} like situations. Furthermore \type
+%D {\c!leftquotation} and \type {\c!leftquote} come into view
+%D \citaat {when we quote} or \citeer {quote} something.
+
+%D \macros
+%D {currentdatespecification}
+%D
+%D Just to make things easy we can ask for the current date
+%D specification by saying:
+
+\def\currentdatespecification%
+ {\getvalue{\??la\currentlanguage\c!datum}}
+
+%D This scommand is not meant for users.
+
+%D Carefull reading of these macros shows that it's legal to
+%D say
+%D
+%D \starttypen
+%D \installlanguage [du ] [de]
+%D \stoptypen
+
+%D \macros
+%D {language,mainlanguage}
+%D {}
+%D
+%D Switching to another language (actually another hyphenation
+%D pattern) is done with:
+%D
+%D \starttypen
+%D \language[identifier]
+%D \stoptypen
+%D
+%D or with \type{\identifier}. Just to be compatible with
+%D \PLAIN\ \TEX, we still support the original meaning, so
+%D
+%D \starttypen
+%D \language=1
+%D \stoptypen
+%D
+%D is a valid operation.
+%D
+%D \showsetup{\y!language}
+%D \showsetup{\y!mainlanguage}
+%D
+%D Both commands take a predefined language identifier as
+%D argument. We can use \type{\mainlanguage[identifier]} for
+%D setting the (indeed) main language. This is the language
+%D used for translating labels like {\em figure} and {\em
+%D table}. The main language defaults to the current language.
+%D
+%D We take care of local as well as standardized language
+%D switching (fr and fa, de and du, but nl and nl).

+%D {}
+%D
+%D Each language has its own typographic pecularities. Some of
+%D those can be influenced by parameters, others are handled by
+%D the interface, but as soon as specific commands come into
+%D view we need another mechanism. In the macro that activates
+%D a language, we call \type{\enablelanguagespecifics}. This
+%D macro in return calls for the setup of language specific
+%D macros. Such specifics are defined as:
+%D
+%D \starttypen
+%D \startlanguagespecifics[de]
+%D \installcompoundcharacter "a {\"a}
+%D \installcompoundcharacter "e {\"e}
+%D \installcompoundcharacter "s {\SS}
+%D \stoplanguagespecifics
+%D \stoptypen
+%D
+%D Instead of \type{[du]} we can pass a comma separated
+%D list, like \type{[du,nl]}. Next calls to this macro add the
+%D specifics to the current list.
+%D
+%D Before we actually read the specifics, we first take some
+%D precautions that will prevent spurious spaces to creep into
+%D the list.
+
+\def\startlanguagespecifics%
+ {\bgroup
+ \catcode`\^^I=\@@ignore
+ \catcode`\^^M=\@@ignore
+ \catcode`\^^L=\@@ignore
+ \dostartlanguagespecifics}
+
+%D The main macro looks quite complicated but actually does
+%D nothing special. By embedding \type{\do} we can easily
+%D append to the lists and also execute them at will. Just to
+%D be sure, we check on spurious spaces.
+
+\long\def\dostartlanguagespecifics[#1]#2\stoplanguagespecifics%
+ {\egroup
+ \long\def\docommando##1%
+ {\doifdefinedelse{\??la##1\??la}
+ {\long\def\do####1####2####3%
+ {\setvalue{\??la####1\??la}{\do{####1}{####2####3}}}%
+ \getvalue{\??la##1\??la}{#2}}

+ \else
+ \showmessage{\m!linguals}{8}{##1}%
+ \fi
+ \egroup}%
+ \processcommalist[#1]\docommando}
+
+%D Enabling them is rather straightforward. We only have to
+%D define \type{\do} in such a way that \type{{ }} is removed
+%D and the language key is gobbled.

+\unprotect

+%D In this module we deal with language dependant labels and
+%D prefixes, like in {\em Figure~12} and {\em Chapter 1}. In
+%D this file we set the default values. Users can easily
+%D overrule these.
+%D
+%D This module is dedicated to the grandfather of Tobias
+%D Burnus, who's extensive languages oriented library helped us
+%D a lot in finding the right translations. All those labels
+%D are collected in files that reflect their common ancestor.
+
+%D \macros
+%D {setupheadtext, setuplabeltext}
+%D
+%D First we present some macros that deal with what we will
+%D call head and label texts. Such texts are defines by:
+%D
+%D \showsetup{\y!setupheadtext}
+%D \showsetup{\y!setuplabeltext}
+%D
+%D In a few paragraphs we'll show quite a lot of examples
+%D of its use.
+
+\def\setupheadtext%
+ {\dosetupsometextprefix\v!kop}
+
+\def\setuplabeltext%
+ {\dosetupsometextprefix\c!label}
+
+\let\handletextprefix=\relax
+
+\def\dodosetupsometextprefix#1%
+ {\def\dododosetupsometextprefix[##1][##2]%
+ {\ifsecondargument
+ \def\docommando####1{\dodocommando[#1##1][####1]}%
+ \processcommalist[##2]\docommando
+ \else
+ \def\docommando####1{\dodocommando[#1\currentmainlanguage][####1]}%
+ \processcommalist[##1]\docommando
+ \fi}%
+ \dodoubleempty\dododosetupsometextprefix}
+
+\def\dosetupsometextprefix#1%
+ {\def\dodocommando[##1][##2=##3]%
+ {\setvalue{##1##2}{\handletextprefix{##3}}}%
+ \dodosetupsometextprefix{#1}}
+
+%D By setting \type{\handletextprefix} to something else than
+%D \type{\relax}, like \type{\uppercase}, one can influence the
+%D conversion.
+%D
+%D These commands accept all kind of inputs:
+%D
+%D \starttypen
+%D \setuplabeltext [language] [label=text]
+%D \setuplabeltext [language] [label=text,label=text,...]
+%D \setuplabeltext [label=text]
+%D \setuplabeltext [label=text,label=text,...]
+%D \stoptypen
+%D
+%D The last two cases concern the current language.
+
+%D \macros
+%D {headtext, labeltext, LABELTEXT}
+%D
+%D Once defined, head and label texts can be called upon using:
+%D
+%D \showsetup{\y!headtext}
+%D \showsetup{\y!labeltext}
+%D
+%D The latter one has an upcased alternative \type{\LABELTEXT}.
+
+\def\headtext%
+ {\dogetupsometextprefix\v!kop}
+
+\def\labeltext%
+ {\dogetupsometextprefix\c!label}
+
+\def\LABELTEXT#1%
+ {\bgroup
+ \let\handletextprefix=\uppercase
+ \the\everyuppercase
+ \dogetupsometextprefix\c!label{#1}% not \labeltext (see \MONTH)
+ \egroup}
+
+\unexpanded\def\dogetupsometextprefix#1#2%
+ {\doifdefinedelse{#1\currentmainlanguage#2}
+ {\getvalue{#1\currentmainlanguage#2}}
+ {\doifdefinedelse{#1#2}
+ {\getvalue{#1#2}}
+ {{\tttf[#1: #2/\currentmainlanguage]~}}}}
+
+%D \macros
+%D {presetheadtext,presetlabeltext}
+%D
+%D The next two macros enable us to automatically define
+%D head and label texts without replacing predefined ones.
+%D This are internal macros.
+
+\def\dopresetsometextprefix#1%
+ {\def\dodocommando[##1][##2=##3]%
+ {\doifundefined{##1##2}
+ {\setvalue{##1##2}{\handletextprefix{##3}}}}%
+ \dodosetupsometextprefix{#1}}
+
+\def\presetheadtext%
+ {\dopresetsometextprefix\v!kop}
+
+\def\presetlabeltext%
+ {\dopresetsometextprefix\c!label}
+
+%D \macros
+%D {translate}
+%D {}
+%D
+%D Sometismes macros contain language specific words that are to
+%D be typeset. Such macros can be made (more) language
+%D independant by using:
+%D
+%D \showsetup{\y!translate}
+%D
+%D like for instance:
+%D
+%D \starttypen
+%D \translate[en=something,nl=iets]
+%D \stoptypen
+%D
+%D which expands to {\em something} or {\em iets}, depending on
+%D de current language.
+
+\def\dotranslate[#1]%
+ {\getparameters[\??lg][#1]%
+ \getvalue{\??lg\currentlanguage}}
+
+\unexpanded\def\translate%
+ {\dosingleempty\dotranslate}
+
+%D When used without argument, the last defined values are
+%D used. This enables repetitive use like
+%D
+%D \starttypen
+%D \en \translate\ means \nl \translate
+%D \stoptypen
+
+%D \macros
+%D {assigntranslation}
+%D {}
+%D
+%D This macro is a system macro, and can be used to assign a
+%D translation to a macro. Its form is:
+%D
+%D \starttypen
+%D \assigntranslation[en=something,nl=iets]\to\command
+%D \stoptypen
+
+\def\assigntranslation[#1]\to#2%
+ {\getparameters[\??lg][#1]%
+ \edef#2{\getvalue{\??lg\currentlanguage}}}

+% File: GB90.8pat
+% Author: Piet Tutelaers (rcpt@urc.tue.nl)
+% Version: betarelease 0.9 (May 1993)
+% Purpose: 8-bit hyphenation patterns for TeX
+% These patterns are generated from the `Groene boekje 1990' (GB90) with
+% the following goals in mind:
+% - provide 8-bit patterns
+% - allow hyphenation in first two and last three letters
+% - inhibit hyphenation before a `trema'
+% - don't hyphenate words in a changing syllable (me-nuu.tje)
+% - don't hyphenate words with different hyphenations (buur.t.je)

+% Hyphenation patterns for Spanish.
+% Compiled by Julio Sanchez (jsanchez@gmv.es) on September 1991.
+%
+% These patterns have been derived from "On Word Division in Spanish",
+% Jos'e A. Ma~nas, Communications of the ACM, and implemented in his
+% package ftc. You can get ftc and a draft of the abovementioned
+% paper from goya.dit.upm.es in src/text.proc/ftc.Z. FTP access may
+% be available. Otherwise, send help to info@goya.dit.upm.es for
+% details on use of the mail server.
+%
+% Rules mentioned below are those described in that paper. After
+% several unsatisfactory attempts to pretend I knew better, these
+% patterns closely follow that paper. Pattern 'tl' is not considered.
+% It is conflictive and ftc does not use it either.
+%
+% These patterns have been generated by shyphen.sh version 1.2,
+% shyphen.sh is a sh script that allows a number of choices.
+% Full benefit from some of these options can only be
+% obtained if appropriate fonts are available.
+%
+% Follows a copyright notice. This is not in the public domain,
+% but the copyright is essentially a hold-harmless clause. That
+% is, use it at will, but don't sue me if you don't like it.
+%
+% COPYRIGHT NOTICE
+%
+% These patterns and the generating sh script are Copyright (c) GMV 1991
+% These patterns were developed for internal GMV use and are made
+% public in the hope that they will benefit others. Also, spreading
+% these patterns throughout the Spanish-language TeX community is
+% expected to provide back-benefits to GMV in that it can help keeping
+% GMV in the mainstream of spanish users. However, this is given
+% for free and WITHOUT ANY WARRANTY. Under no circumstances can Julio
+% Sanchez, GMV, Jos'e A. Ma~nas or any agents or representatives thereof
+% be held responsible for any errors in this software nor for any damages

+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. Non||commercial use is
+%C granted.
+
+%D In this module we define the commands. A more than quick
+%D glance at this list leans that it's incomplete. This is due
+%D to the fact that the system generated a lot of commands by
+%D means of the elements specified somewhere else.
+%D
+%D {\em Because the original interface to \CONTEXT\ is dutch,
+%D the words left of the \type{:} are in dutch. In the near
+%D future english will be the core language.}
+
+\writestatus{loading}{Context Multilingual Macros / Commands}
+
+%D The commands are grouped according to their functionality.
+%D Although the \type{\stop} counterpart of the
+%D \type{\start}||commands could be generated automatically,
+%D we've chosen do define it explicitly.
+%D
+%D One complication of the english commands, is that we don't
+%D want them to overrule or conflict with Plain \TEX. The
+%D names therefore are not always optimal.

+%D In the system modules we introduced some prefixed constants,
+%D variables (both macros) and registers. Apart from a
+%D tremendous saving in terms of memory and a gain in speed we
+%D use from now on prefixes when possible for just another
+%D reason: consistency and multi||linguality. Systematically
+%D using prefixed macros enables us to implement a
+%D multi||lingual user interface. Redefining these next set of
+%D prefixes therefore can have desastrous results.

+%D
+%D The first part of this module is dedicated to dealing with
+%D multi||lingual constants and variables. When \CONTEXT\ grew
+%D bigger and bigger in terms of bytes and used string space,
+%D we switched to predefined constants. At the cost of more
+%D hash table entries, the macros not only becase more compact,
+%D they became much faster too. Maybe an even bigger advantage
+%D was that mispelling could no longer lead to problems. Even a
+%D multi||lingual interface became possible.
+%D
+%D Constants --- we'll introduce the concept of variables later
+%D on --- are preceded by a type specific prefix, followed by a
+%D \type{!}. To force consistency, we provide a few commands
+%D for defining such constants.
+%D
+%D \starttypen
+%D \defineinterfaceconstant {name} {meaning}
+%D \defineinterfacevariable {name} {meaning}
+%D \defineinterfaceelement {name} {meaning}
+%D \stoptypen
+%D
+%D Which is the same as:
+%D
+%D \starttypen
+%D \def\c!name{meaning}
+%D \def\v!name{meaning}
+%D \def\e!name{meaning}
+%D \stoptypen
+
+\def\defineinterfaceconstant #1#2{\setvalue{\c!prefix!#1}{#2}}
+\def\defineinterfacevariable #1#2{\setvalue{\v!prefix!#1}{#2}}
+\def\defineinterfaceelement #1#2{\setvalue{\e!prefix!#1}{#2}}
+
+%D Next come some interface independant constants:
+%D
+%D \starttypen
+%D \definereferenceconstant {name} {meaning}
+%D \definefileconstant {name} {meaning}
+%D \stoptypen
+
+\def\definereferenceconstant #1#2{\setvalue{\r!prefix!#1}{#2}}
+\def\definefileconstant #1#2{\setvalue{\f!prefix!#1}{#2}}
+
+%D And finaly we have the one argument, space saving constants
+%D
+%D \starttypen
+%D \definesystemconstant {name}
+%D \definemessageconstant {name}
+%D \stoptypen
+
+\def\definesystemconstant #1{\setvalue{\s!prefix!#1}{#1}}
+\def\definemessageconstant #1{\setvalue{\m!prefix!#1}{#1}}
+
+%D In a parameter driven system, some parameters are shared
+%D by more system components. In \CONTEXT\ we can distinguish
+%D parameters by a unique prefix. Such a prefix is defined
+%D with:
+%D
+%D \starttypen
+%D \definesystemvariable {name}
+%D \stoptypen
+
+\def\definesystemvariable #1{\setvalue{\??prefix#1}{\@@prefix#1}}
+
+%D \macros
+%D {selectinterface,
+%D defaultinterface, currentinterface, currentresponses}
+%D {}
+%D
+%D With \type{\selectinterface} we specify the language we are
+%D going to use. The system asks for the language wanted, and
+%D defaults to \type{\currentinterface} when we just give
+%D \type{enter}. By default the message system uses the
+%D current interface language, but \type{\currentresponses}
+%D can specify another language too.
+%D
+%D Because we want to generate formats directly too, we do
+%D not ask for interface specifications when these are already
+%D defined (like in cont-nl.tex and alike).

+%D {startmessages,
+%D getmessage,
+%D showmessage,
+%D makemessage}
+%D {}
+%D
+%D A package as large as \CONTEXT\ can hardly function without
+%D a decent message mechanism. Due to its multi||lingual
+%D interface, the message subsystem has to be multi||lingual
+%D too. A major drawback of this feature is that we have to
+%D code messages. As a result, the source becomes less self
+%D documented. On the other hand, consistency will improve.
+%D
+%D Because the overhead in terms of entries in the (already
+%D exhausted) hash table has to be minimal, messages are packed
+%D in libraries. We can extract a message from such a library
+%D in three ways:
+%D
+%D \starttypen
+%D \getmessage {library} {tag}
+%D \showmessage {library} {tag} {data}
+%D \makemessage {library} {tag} {data}
+%D \stoptypen
+%D
+%D The first command gets the message \type{tag} from the
+%D \type{library} specified. The other commands take an extra
+%D argument: a list of items to be inserted in the message
+%D text. While \type{\showmessage} shows the message at the
+%D terminal, the other commands generate the message as text.
+%D Before we explain the \type{data} argument, we give an
+%D example of a library.
+%D
+%D \starttypen
+%D \startmessages english library: alfa
+%D title: something
+%D 1: first message
+%D 2: second (--) message --
+%D \stopmessages
+%D \stoptypen
+%D
+%D The first message is a simple one and can be shown with:
+%D
+%D \starttypen
+%D \showmessage {alfa} {1} {}
+%D \stoptypen
+%D
+%D The second message on the other hand needs some extra data:
+%D
+%D \starttypen
+%D \showmessage {alfa} {2} {and last,to you}
+%D \stoptypen
+%D
+%D This message is shown as:
+%D
+%D \starttypen
+%D something : second (and last) message to you
+%D \stoptypen
+%D
+%D As we can see, the title entry is shown with the message.
+%D The data fields are comma separated and are specified in the
+%D message text by \type{--}.
+%D
+%D It is not required to define all messages in a library at
+%D once. We can add messages to a library in the following way:
+%D
+%D \starttypen
+%D \startmessages english library: alfa
+%D 10: tenth message
+%D \stopmessages
+%D \stoptypen
+%D
+%D Because such definitions can take place in different
+%D modules, the system gives a warning when a tag occurs more
+%D than once. The first occurrence takes preference over later
+%D ones, so we had better use a save offset, as shown in the
+%D example. As we can see, the title field is specified only
+%D the first time!
+%D
+%D Because we want to check for duplicate tags, the macros
+%D are a bit more complicated than neccessary. The \NEWLINE\
+%D token is used as message separator.

+%D
+%D Turning off messages also turns off warnings, which is

+%D
+%D We already defined these auxiliary macros in the system
+%D modules. Starting with this module however, we have to take
+%D multi||linguality a bit more serious.
+%D
+%D First we show a well||defined alternative:
+%D
+%D \starttypen
+%D \def\dosetvalue#1#2#3%
+%D {\doifdefinedelse{\c!prefix!#2}
+%D {\setvalue{#1\getvalue{\c!prefix!#2}}{#3}}

+%D {\setvalue{#1#3}%
+%D {\getvalue{#2#3}}}}
+%D
+%D \def\dogetvalue#1#2%
+%D {\getvalue{#1\getvalue{\c!prefix!#2}}}
+%D \stoptypen
+%D
+%D These macros are called upon quite often and so we optimized
+%D them a bit.
+
+\def\dosetvalue#1#2#3%

+ {\dosetvalue{#1}{#2}{}}
+
+\def\dogetvalue#1#2%
+ {\csname#1\csname\c!prefix!#2\endcsname\endcsname}
+
+%D Although maybe bot clearly visible, there is a
+%D considerable profit in further optimalization. By expanding
+%D the embedded \type{\csname} we can reduce the format file
+%D by about 5\% (60~KB out of 1.9~MB).

+ \fi}
+
+%D We take this opportunity of redefining to adapt an
+%D assignment macro. The change has to do with the fact that the
+%D generated error message must be multi||lingual. We can not
+%D define the message yet, because we still have to select the
+%D interface language.

+%D \CONTEXT\ is a parameter driven package. This means that
+%D users instruct the system by means of variables, values and
+%D keywords. These instructions take the form:
+%D
+%D \starttypen
+%D \setupsomething[some variable=some value, another one=a keyword]
+%D \stoptypen
+%D
+%D or by keyword only:
+%D
+%D \starttypen
+%D \dosomething[this way, that way, no way]
+%D \stoptypen
+%D
+%D Because the same variables can occur in more than one setup
+%D command, we have to be able to distinguish them. This is
+%D achieved by assigning them a unique prefix.
+%D
+%D Imagine a setup command for boxed text, that enables us to
+%D specify the height and width of the box. Behide the scenes
+%D the command
+%D
+%D \starttypen
+%D \setupbox [width=12cm, height=3cm]
+%D \stoptypen
+%D
+%D results in something like
+%D
+%D \starttypen
+%D \<box><width> {12cm}
+%D \<box><height> {3cm}
+%D \stoptypen
+%D
+%D while a similar command for specifying the page dimensions
+%D of an \kap{A4} page results in:
+%D
+%D \starttypen
+%D \<page><width> {21.0cm}
+%D \<page><height> {27.9cm}
+%D \stoptypen
+%D
+%D The prefixes \type{<box>} and \type{<page>} are hidden from
+%D users and can therefore be language independant. Variables
+%D on the other hand, differ for each language:
+%D
+%D \starttypen
+%D \<box><color> {<blue>}
+%D \<box><kleur> {<blauw>}
+%D \<box><couleur> {<blue>}
+%D \stoptypen
+%D
+%D In this example we can see that the assigned values or
+%D keywords are language dependant too. This will be a
+%D complication when defining multi||lingual setup files.
+%D
+%D A third phenomena is that variables and values can have a
+%D similar meaning.
+%D
+%D \starttypen
+%D \<pagenumber><location> {<left>}
+%D \<skip><left> {12cm}
+%D \stoptypen
+%D
+%D A (minor) complication is that where in english we use
+%D \type{<left>}, in dutch we find both \type{<links>} and
+%D \type{<linker>}. This means that when we use some sort of
+%D translation table, we have to distinguish between the
+%D variables at the left side and the fixed values at the
+%D right.
+%D
+%D The same goes for commands that are composed of different
+%D user supplied and/or language specific elements. In english
+%D we can use:
+%D
+%D \starttypen
+%D \<empty><figure>
+%D \<empty><intermezzo>
+%D \stoptypen
+%D
+%D But in dutch we have the following:
+%D
+%D \starttypen
+%D \<lege><figuur>
+%D \<leeg><intermezzo>
+%D \stoptypen
+%D
+%D These subtle differences automatically lead to a solution
+%D where variables, values, elements and other components have
+%D a similar logical name (used in macro's) but a different
+%D meaning (supplied by the user).
+%D
+%D Our solution is one in which the whole system is programmed
+%D in terms of identifiers with language specific meanings. In
+%D such an implementation, each fixed variable is available as:
+%D
+%D \starttypen
+%D \<prefix><variable>
+%D \stoptypen
+%D
+%D This means that for instance:
+%D
+%D \starttypen
+%D \setupbox[width=12cm]
+%D \stoptypen
+%D
+%D expands to something like:
+%D
+%D \starttypen
+%D \def\boxwidth{12cm}
+%D \stoptypen
+%D
+%D because we don't want to recode the source, a setup command
+%D in another language has to expand to this variable, so:
+%D
+%D \starttypen
+%D \stelblokin[breedte=12cm]
+%D \stoptypen
+%D
+%D has to result in the definition of \type{\boxwidth} too.
+%D This method enables us to build compact, fast and readable
+%D code.
+%D
+%D An alternative method, which we considered using, uses a
+%D more indirect way. In this case, both calls generate a
+%D different variable:
+%D
+%D \starttypen
+%D \def\boxwidth {12cm}
+%D \def\boxbreedte {12cm}
+%D \stoptypen
+%D
+%D And because we don't want to recode those megabytes of
+%D already developed code, this variable has to be called with
+%D something like:
+%D
+%D \starttypen
+%D \valueof\box\width
+%D \stoptypen
+%D
+%D where \type{\valueof} takes care of the translation of
+%D \type{width} or \type{breedte} to \type{width} and
+%D combining this with \type{box} to \type{\boxwidth}.
+%D
+%D One advantage of this other scheme is that, within certain
+%D limits, we can implement an interface that can be switched
+%D to another language at will, while the current approach
+%D fixes the interface at startup. There are, by the way,
+%D other reasons too for not choosing this scheme. Switching
+%D user generated commands is for instance impossible and a
+%D dual interface would therefore give a strange mix of
+%D languages.
+%D
+%D Now let's work out the first scheme. Although the left hand
+%D of the assignment is a variable from the users point of
+%D view, it is a constant in terms of the system. Both
+%D \type{width} and \type{breedte} expand to \type{width}
+%D because in the source we only encounter \type{width}. Such
+%D system constants are presented as
+%D
+%D \starttypen
+%D \c!width
+%D \stoptypen
+%D
+%D This constant is always equivalent to \type{width}. As we
+%D can see, we use \type{c!} to mark this one as constant. Its
+%D dutch counterpart is:
+%D
+%D \starttypen
+%D \c!breedte
+%D \stoptypen
+%D
+%D When we interpret a setup command each variable is
+%D translated to it's \type{c!} counterpart. This means that
+%D \type{breedte} and \type{width} expand to \type{\c!breedte}
+%D and \type{\c!width} which both expand to \type{width}. That
+%D way user variables become system constants.
+%D
+%D The interpretation is done by means of a general setup
+%D command \type{\getparameters} that we introduced in the
+%D system module. Let us define some simple setup command:
+%D
+%D \starttypen
+%D \def\setupbox[#1]%
+%D {\getparameters[\??bx][#1]}
+%D \stoptypen
+%D
+%D This command can be used as:
+%D
+%D \starttypen
+%D \setupbox [width=3cm, height=1cm]
+%D \stoptypen
+%D
+%D Afterwards we have two variables \type{\@@bxwidth} and
+%D \type{\@@bxheight} which have the values \type{3cm} and
+%D \type{1cm} assigned. These variables are a combinatiom of
+%D the setup prefix \type{\??bx}, which expands to \type{@@bx}
+%D and the translated user supplied variables \type{width} and
+%D \type{height} or \type{breedte} and \type{hoogte},
+%D depending on the actual language. In dutch we just say:
+%D
+%D \starttypen
+%D \stelblokin [breedte=3cm, hoogte=1cm]
+%D \stoptypen
+%D
+%D and get ourselves \type{\@@bxwidth} and \type{\@@bxheight}
+%D too. In the source of \CONTEXT, we can recognize constants
+%D and variables on their leading \type{c!}, \type{v!} etc.,
+%D prefixes on \type{??} and composed variables on \type{@@}.
+%D
+%D We already saw that user supplied keywords need some
+%D special treatment too. This time we don't translate the
+%D keyword, but instead use in the source a variable which
+%D meaning depends on the interface language.
+%D
+%D \starttypen
+%D \v!left
+%D \stoptypen
+%D
+%D Which can be used in macro's like:
+%D
+%D \starttypen
+%D \processaction
+%D [\@@bxlocation]
+%D [ \v!left=>\dosomethingontheleft,
+%D \v!middle=>\dosomthinginthemiddle,
+%D \v!right=>\dosomethingontheright]
+%D \stoptypen
+%D
+%D Because variables like \type{\@@bxlocation} can have a lot
+%D of meanings, including tricky expandable tokens, we cannot
+%D translate this meaning when we compare. This means that
+%D \type{\@@bxlocation} can be \type{left} of \type{links} of
+%D whatever meaning suits the language. But because
+%D \type{\v!left} also has a meaning that suits the language,
+%D we are able to compare.
+%D
+%D Although we know it sounds confusing we want to state two
+%D important characteristics of the interface as described:
+%D
+%D \startsmaller \em
+%D user variables become system constants
+%D \stopsmaller
+%D
+%D and
+%D
+%D \startsmaller \em
+%D user constants (keywords) become system variables
+%D \stopsmaller
+%D
+
+%D \macros
+%D {startconstants,startvariables}
+%D {}
+%D
+%D It's time to introduce the macro's that are responsible for
+%D this translations process, but first we show how constants
+%D and variables are defined. We only show two languages and
+%D a few words.
+%D
+%D \starttypen
+%D \startconstants english dutch
+%D
+%D width: width breedte
+%D height: height hoogte
+%D
+%D \stopconstants
+%D \stoptypen
+%D
+%D Keep in mind that what users see as variables, are constants
+%D for the system.
+%D
+%D \starttypen
+%D \startvariables english dutch
+%D
+%D location: left links
+%D text: text tekst
+%D
+%D \stopvariables
+%D \stoptypen
+%D
+%D The macro's responsible for interpreting these setups are
+%D shared. They take care of empty lines and permit a more or
+%D less free format. All setups accept the keyword \type{all}
+%D which equals every language.

+%D The constants and variables are defined as described. When
+%D \type{\interfacetranslation} is \type{true}, we also
+%D generate a reverse translation. Because we don't want to put
+%D too big a burden on \TEX's hash table, this is no default
+%D behavior. Reverse translation is used in the commands that
+%D generate the quick reference cards. We are going to define
+%D the real \CONTEXT\ commands in an abstract way and generate
+%D those reference cards for each language without further
+%D interference.

+\def\startconstants%
+ {\startinterfaceobjects\setinterfaceconstant\stopconstants}

+%D \macros
+%D {defineinterfaceconstant}
+%D
+%D Next we redefine a previously defined macro to take care of
+%D interface translation too. It's a bit redundant, because
+%D in thise situations we could use the c||version, but for
+%D documentation purposes the x||alternative comes in handy.
+
+\def\defineinterfaceconstant#1#2%

+ \ifinterfacetranslation
+ \setvalue{\x!prefix!#1}{#2}%
+ \fi}
+
+%D \macros
+%D {startinterfacesetupconstant}
+%D {}
+%D
+%D The next command, \type{\startinterfacesetupconstant}, which
+%D behavior also depends on the boolean, is used for constants
+%D that are only needed in these quick reference macro's. The
+%D following, more efficient approach does not work here,
+%D because it sometimes generates spaces.
+%D
+%D \starttypen
+%D \def\setinterfacesetupconstant%
+%D {\ifinterfacetranslation
+%D \expandafter\setinterfaceconstant
+%D \fi}
+%D \stoptypen
+%D
+%D We therefore use the more redundant but robust method:
+
+\def\setinterfacesetupvariable#1#2%
+ {\ifinterfacetranslation
+ \doifelse{#2}{\nointerfaceobject}
+ {\setvalue{\y!prefix!#1}{#1}}
+ {\setvalue{\y!prefix!#1}{#2}}%
+ \fi}
+
+\def\startsetupvariables%
+ {\startinterfaceobjects\setinterfacesetupvariable\stopsetupvariables}
+
+%D \macros
+%D {startelements}
+%D {}
+%D
+%D Due to the object oriented nature of \CONTEXT, we also need
+%D to define the elements that are used to build commands:
+%D
+%D \starttypen
+%D \startelements english dutch
+%D
+%D beginof: beginof beginvan
+%D eindof: endof eindvan
+%D start: start start
+%D stop: stop stop
+%D
+%D \stopelements
+%D \stoptypen
+%D
+%D Such elements sometimes are the same in diferent
+%D languages, but mostly they differ. Things can get even
+%D confusing when we look at for instance the setup commands.
+%D In english we say \type{\setup<something>}, but in dutch we
+%D have: \type{\stel<iets>in}. Such split elements are no
+%D problem, because we just define two elements. When no second
+%D part is needed, we use a \type{-}:
+%D
+%D \starttypen
+%D \startelements english dutch
+%D
+%D setupa: setup stel
+%D setupb: - in
+%D
+%D \stopelements
+%D \stoptypen
+%D
+%D Element translation is realized by means of:
+
+\def\setinterfaceelement#1#2%
+ {\doifelse{#2}{\nointerfaceobject}
+ {\debuggerinfo{element}{#1 defined as <empty>}%
+ \setvalue{\e!prefix!#1}{}}
+ {\doifdefinedelse{\e!prefix!#1}
+ {\doifnot{\getvalue{\e!prefix!#1}}{#2}
+ {\debuggerinfo{element}{#1 redefined as #2}%
+ \setvalue{\e!prefix!#1}{#2}}}
+ {\debuggerinfo{element}{#1 defined as #2}%
+ \setvalue{\e!prefix!#1}{#2}}}}
+
+\def\startelements%
+ {\startinterfaceobjects\setinterfaceelement\stopelements}
+
+%D \macros
+%D {startcommands}
+%D {}
+%D
+%D The last setup has to do with the commands themselve.
+%D Commands are defined as:
+%D
+%D \starttypen
+%D \startcommands english dutch
+%D
+%D starttekst: starttext starttekst
+%D stoptekst: stoptext stoptekst
+%D omlijnd: framed omlijnd
+%D margewoord: marginword margewoord
+%D
+%D \stopcommands
+%D \stoptypen
+%D
+%D Here we also have to take care of the optional translation
+%D needed for reference cards.
+
+\def\setinterfacecommand#1#2%
+ {\doifelse{#2}{\nointerfaceobject}
+ {\debuggerinfo{command}{no link to #1}%
+ \setinterfacesetupvariable{#1}{#1}}
+ {\doifelse{#1}{#2}
+ {\debuggerinfo{command}{#1 remains #1}}
+ {\doifdefinedelse{#2}

+
+\def\startcommands%
+ {\startinterfaceobjects\setinterfacecommand\stopcommands}
+
+%D \macros
+%D {getinterfaceconstant, getinterfacevariable}
+%D {}
+%D
+%D Generating the interface translation macro's that are used
+%D in the reference lists, is enabled by setting the boolean:
+%D
+%D \starttypen
+%D \interfacetranslationtrue
+%D \stoptypen
+%D
+%D Keep in mind that enabling interfacetranslation costs a
+%D bit of hash space.
+
+\newif\ifinterfacetranslation
+
+\def\getinterfaceconstant#1%
+ {\ifinterfacetranslation
+ \doifdefinedelse{\x!prefix!#1}
+ {\getvalue{\x!prefix!#1}}
+ {#1}%
+ \else
+ #1%
+ \fi}
+
+\def\getinterfacevariable#1%
+ {\ifinterfacetranslation
+ \doifdefinedelse{\y!prefix!#1}
+ {\getvalue{\y!prefix!#1}}
+ {#1}%
+ \else
+ #1%
+ \fi}
+
+%D When a reference list is generated, one does not need to
+%D generate a new format. Just reloading the relevant
+%D definition files suits:
+%D
+%D \starttypen
+%D \interfacetranslationtrue
+%D \input mult-con
+%D \input mult-com
+%D \stoptypen
+
+%D \macros
+%D {interfaced}
+%D {}
+%D
+%D The setup commands translate the constants automatically.
+%D When we want to translate 'by hand' we can use the simple
+%D but effective command:
+%D
+%D \starttypen
+%D \interfaced {something}
+%D \stoptypen
+%D
+%D Giving \type{\interfaced{breedte}} results in \type{width}
+%D or, when not defined, in \type{breedte} itself.
+
+\def\interfaced#1%
+ {\expandafter\ifx\csname\c!prefix!#1\endcsname\relax
+ #1%
+ \else
+ \csname\c!prefix!#1\endcsname
+ \fi}
+
+%D So much for the basic multi||lingual interface commands. The
+%D macro's can be enhanced with more testing facilities, but
+%D for the moment they suffice.

+%D The word \type{height} takes 6~token memory cells. The
+%D control sequence \type{\height} on the other hand uses only
+%D one. Knowing this, we can improve the performance of \TEX,
+%D both is terms of speed and memory usage, by using control
+%D sequences instead of the words written in full.
+%D
+%D Where in the \ASCII\ file the second lines takes nine extra
+%D characters, \TEX\ saves us 13~tokens.

+%D \hrule width 10pt height 2pt depth 1pt
+%D \hrule \!!width 10pt \!!height 2pt \!!depth 1pt

+%D
+%D One condition is that we have defined \type{\!!height},
+%D \type{\!!width} and \type{\!!depth} as respectively
+%D \type{height}, \type{width} and \type{depth}. Using this
+%D scheme therefore only makes sense when a token sequence is
+%D used more than once. Savings like this should of course be
+%D implemented in english, just because \TEX\ is english.

+%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 {temporaryextension} {tmp}
+\definefileconstant {patternsextension} {pat}
+\definefileconstant {hyphensextension} {hyp}
+
+%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 {systemfilename} {cont-sys}
+\definefileconstant {oldfilename} {cont-old}
+\definefileconstant {newfilename} {cont-new}
+
+%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 {languageprefix} {lang-}
+\definefileconstant {fontprefix} {font-}
+\definefileconstant {colorprefix} {colo-}
+\definefileconstant {specialprefix} {spec-}
+
+%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 {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.
+
+\selectinterface
+
+%D And only after this selection is done, we can define
+%D messages, otherwise the default language is in use.

+% Allocation of registers
+
+% Here are macros for the automatic allocation of \count, \box, \dimen,
+% \skip, \muskip, and \toks registers, as well as \read and \write
+% stream numbers, \fam codes, \language codes, and \insert numbers.
+
+\message{registers,}
+
+% When a register is used only temporarily, it need not be allocated;
+% grouping can be used, making the value previously in the register return
+% after the close of the group. The main use of these macros is for
+% registers that are defined by one macro and used by others, possibly at
+% different nesting levels. All such registers should be defined through
+% these macros; otherwise conflicts may occur, especially when two or more
+% more macro packages are being used at once.
+
+% The following counters are reserved:
+% 0 to 9 page numbering
+% 10 count allocation
+% 11 dimen allocation
+% 12 skip allocation
+% 13 muskip allocation
+% 14 box allocation
+% 15 toks allocation
+% 16 read file allocation
+% 17 write file allocation
+% 18 math family allocation
+% 19 language allocation
+% 20 insert allocation
+% 21 the most recently allocated number
+% 22 constant -1
+% New counters are allocated starting with 23, 24, etc. Other registers are
+% allocated starting with 10. This leaves 0 through 9 for the user to play
+% with safely, except that counts 0 to 9 are considered to be the page and
+% subpage numbers (since they are displayed during output). In this scheme,
+% \count 10 always contains the number of the highest-numbered counter that
+% has been allocated, \count 14 the highest-numbered box, etc.
+% Inserts are given numbers 254, 253, etc., since they require a \count,
+% \dimen, \skip, and \box all with the same number; \count 20 contains the
+% lowest-numbered insert that has been allocated. Of course, \box255 is
+% reserved for \output; \count255, \dimen255, and \skip255 can be used freely.
+
+% It is recommended that macro designers always use
+% \global assignments with respect to registers numbered 1, 3, 5, 7, 9, and
+% always non-\global assignments with respect to registers 0, 2, 4, 6, 8, 255.
+% This will prevent ``save stack buildup'' that might otherwise occur.

+%D Specials are \TEX's channel to the outside world. They make
+%D \TEX\ even more platform independant and permit easy
+%D adaption to new developments. One major drawback of specials
+%D is that they have to be supported by printer drivers. We've
+%D tried to overcome this problem by implementinmg specials as
+%D a sort of drivers themselves.

+%D Because there is no standardization in the use of specials,
+%D more than one driver or program can be supported. The
+%D specials are grouped in libraries. Some of these are
+%D general, such as the \type{postscript} library, some are
+%D tuned to a special kind of program, like the \type{pdf}
+%D ones, and some support a specific driver, as we can see in
+%D the \type{yandy} library. A library is build with the
+%D commands:
+%D
+%D \starttypen
+%D \startspecials[name][inheritance]
+%D
+%D \definespecial\none{...}
+%D \definespecial\onlyone#1{...}
+%D \definespecial\alot#1#2#3#4{...}
+%D
+%D \stopspecials
+%D \stoptypen
+%D
+%D Because drivers show some overlap in their support of
+%D specials, a mechanism of inheritance is implemented. The
+%D predefined libraries show this feature.
+%D
+%D Every special has to be predefined first. We do this with
+%D the command:
+%D
+%D \starttypen
+%D \installspecial [\none] [and] [0]
+%D \installspecial [\onlyone] [and] [1]
+%D \installspecial [\alot] [or] [4]
+%D \stoptypen
+%D
+%D This means as much as: there is a special names
+%D \type{\none} which has no arguments and has more than one
+%D appearance. The special \type{\alot} on the other hand has
+%D four arguments and is only defined once. Every instance in
+%D the libraries of a special of category \type{and} is
+%D executed when called upon, but only one special of
+%D category \type{or} can be active. Most of the
+%D \type{postscript}||specials are of category \type{or},
+%D because they tend to interfere with driver specific ones.
+%D The interactive specials of \type{dviwindo} and \type{pdf}
+%D are an example of specials that can be called both.
+%D
+%D A library is defined in a file with the name
+%D \type{spec-...}. We load a library with the command:
+%D
+%D \starttypen
+%D \usespecials [list]
+%D \stoptypen
+%D
+%D where the list can contain one or more file tags, the
+%D \type{...} in the filename. The keyword \type{reset}
+%D resets all loaded specials. This is equivalent to
+%D \type{\resetspecials}.
+
+%D Although a mechanism of nesting can be implemented, we
+%D prefer to use a inheritance mechanism as mentioned. Calls
+%D upon \type{\usespecials} within a \type{\startspecials}
+%D would lead to confusion and errors.
+
+\newif\ifinheritspecials
+
+%D We define some local constants and variables. They look a
+%D bit horrible but we don't want conflicts.

+%D Every library has a unique name, which is given as the first

+%D overruled. The name may differ from the file||tag.
+%D
+%D The optional second argument can consist of a list of
+%D libraries that are to be loaded first. This list can contain
+%D file||tags or names of libraries. Names are often more

+%D We have to install specials before we can define and use
+%D them. The command itself is defined as a call to another
+%D command that executes one or more user||defined specials,
+%D depending of it's category: \type{or} versus \type{and}.
+%D
+%D The command \type{\installspecial} takes three
+%D (non||optional) arguments: the name of the command, the
+%D category it belongs to and the number of arguments it
+%D takes.
+%D
+%D With \type{\resetspecials} we can unload the predefined
+%D specials.

+%D The command \type{\definespecial} take the place of

+%D sure, we first check if the command is permitted, i.e.
+%D installed. If not, we give a warning and gobble the
+%D illegal command in an quite elegant way.
+%D
+%D If the command can be combined (\type{and}) with others,
+%D we append it to a list, otherwise (\type{or}) it becomes
+%D the only item in the list.

+%D The command \type{\executespecials} is used to execute the
+%D defined specials. Once a special is installed, the special
+%D itself calls for this command, so it's not needed outside
+%D this module. One can use it if wanted.
+%D
+%D A former implementation grouped the execution. Recent
+%D additions however |<|like the specials that implement object
+%D handling|>| asked for non||grouped execution.

+%D We start with the installation of color and grayscale
+%D specials. The values are in the range 0..1 (e.g. 0.25).
+%D
+%D \starttypen

+%D
+%D Because we can expect conflicts between drivers, we
+%D implement them as category \type{or}. In previous versions

+%D Probably the most problematic special is the following

+%D
+%D \starttypen
+%D \doinsertfile {type,method} {file} {xscale} {yscale} {x} {y} {w} {h} {options}
+%D \stoptypen
+%D
+%D The scale is given percents, the other values are base
+%D points.
+%D
+%D The special is implemented as \type{or}. Because
+%D \DVIPSONE\ understands them all, a chain of alternatives
+%D would generate multiple courrences of the same
+%D illustration.

+%D When option 1 is passed, the viewers is asked to present a

+%D

+%D
+%D Here come some obscure interactive commands. Probably the

+%D use them.
+%D
+%D The first ones can be used to set up the interaction.
+%D
+%D \starttypen
+%D \dosetupinteraction
+%D \stoptypen
+%D
+%D Normally this command does nothing but giving a message
+%D that some scheme is supported. Postscript prolog files
+%D can best be loaded by the printer driver program.
+%D
+%D The second one sets up the screen. It takes three
+%D arguments:
+%D
+%D \starttypen
+%D \dosetupscreen {hoffset} {voffset} {width} {height} {options}
+%D \stoptypen
+%D

+%D {}
+%D
+%D The interactive real work is done by the following four
+%D specials. The reason for providing the first one with both
+%D a label and a number, is a result of the quite poor
+%D implementation of \type{pdfmarks} in version 1.0 of
+%D Acrobat. Because only pagenumbers were supported as
+%D destination, we had to provide both labels (\DVIWINDO) and
+%D pagenumbers (\PDF). Some drivers use start stop pairs.
+%D

+%D \dostartgotolocation {w} {h} {url} {file} {label} {page}
+%D \dostartgotorealpage {w} {h} {url} {file} {page}

+%D
+%D Their counterparts are:
+%D
+%D \starttypen
+%D \dostopgotolocation
+%D \dostopgotorealpage
+%D \stoptypen
+%D
+%D The internal alternative is used for system||generated
+%D links, the external one for user||generated links. The

+%D
+%D \starttypen

+%D \stoptypen
+%D
+%D These commands are accompanied by:

+%D In \PDF\ version 1.0 only page references were supported,

+%D continuous support of version 1.1 viewers for \MSDOS\
+%D therefore sometimes forces us to prefer page references. As
+%D a bonus, they are faster too and have no limitations. How

+%D This macro at least tries to convert a arbitrary string

+%D change the glyph as well as converts sensisitve ones into a

+%D These specials are not as beautiful as they should be. The
+%D main reason for this is that we started with \DVIWINDO,
+%D which lacks support of \EPS||insertions, but offered a
+%D powerfull linking mechanism. The first version
+%D of \PDF\ did not support labels but only pagenumbers.
+%D This dreadfull omission was corrected in version 2.0, but
+%D we continue to support both alternatives. One never knows.
+%D
+%D Although the concepts behind the \type{pdfmark}'s are
+%D still far from perfect, version 2.1 brought another
+%D change. This time the format was changed. So much for
+%D upward compatibility.

+%D This implementation is a mixture of several possible
+%D implementations. We use some constants that may not be
+%D changed. It took some time to find them, but these values
+%D offer quite accurate results. The macro calls for
+%D \type{\forgetall}, which resets indentation, skips and
+%D \type{\everypar}.
+%D
+%D Because a stroke follows the line, we correct for half of
+%D the linewidth. Furthermore we use scaling to overcome some
+%D limitations in the precision ($<1$~sp) and to prevent
+%D rounding errors. We also do some correction for large
+%D values. We let PostScript compare some arguments with
+%D \type{a b eq {action} fi}.
+%D
+%D The path is based on a macro of J.~Hefferon cs. We also
+%D tried the D.~Salomon implementation, but this did not work

+%D author=Hans Hagen,

+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. Non||commercial use is

+
+%D Being one of the first typographical systems able to support
+%D advances \PDF\ support, \TEX\ is also one of the first
+%D systems to produce high quality \PDF\ code directly. Thanks
+%D to Han The Thanh c.s. the \TEX\ community can leap forward
+%D once again.
+%D
+%D One important characteristic of \PDFTEX\ is that is can
+%D produce standard \DVI\ code as well as \PDF\ code. This
+%D enables us to use one format file to support both output
+%D formats.
+%D
+%D All modules in this group use specials to tell drivers what
+%D non||\TEX\ actions to take. Because from the \TEX\ point of
+%D view, there is no difference between \DVI\ and \PDF, we
+%D therefore only have to bend the \DVI\ driver support into
+%D \PDF\ support. Technically spoken, specials no longer serve
+%D a purpose, except from ending up as comment in the \PDF\
+%D file. The core primitive in this module therefore is the
+%D \PDFTEX\ primitive \type{\pdfliteral}.
+%D
+%D Before we continue we need to make sure if indeed those
+%D \PDFTEX\ primitives are permitted. If no primitives are
+%D available, we just stop reading any further.
+
+\ifx\pdfoutput\undefined \endinput \else \unprotect \fi
+
+%D Once we are sure that we're indeed supporting \PDFTEX, we
+%D force \PDF\ output at the highest compression. For debugging
+%D purposes one can set the compresslevel to~0.
+
+\pdfoutput =1
+\pdfcompresslevel=9
+
+%D Now we have to make sure no other specials are supported,
+%D else \PDFTEX\ will keep on telling us that we're wrong.
+
+\unprotected \usespecials[\v!reset]
+
+%D Just in case we mimmick specials, we have to make sure no
+%D default specials end up in the process.
+
+\let\defaultspecial=\gobbleoneargument
+
+%D Having reset all the special support, we have to define
+%D all needed and possible support in this module.
+
+\startspecials[tpd]
+
+%D This means that by saying
+%D
+%D \starttypen
+%D \usespecials[tpd]
+%D \stoptypen
+%D
+%D we get ourselves \PDF\ output.
+
+%D \macros
+%D {dosetuppaper}
+%D
+%D If we don't set the paper size, \PDFTEX\ will certainly do
+%D it in a way we don't want, therefore we need:
+
+\def\dosetuppdftexpaper#1#2#3%
+ {\global\pdfpagewidth =#2\relax
+ \global\pdfpageheight=#3\relax
+ \global\let\dosetuppdftexpaper=\gobblethreearguments}

+
+%D \macros
+%D {doinsertfile}
+%D
+%D Graphics are not part of \TEX\ and therefore not part of the
+%D \DVI\ standard. \PDF\ on the other hand has several graphic
+%D primitives. During the multi||step process \TEX\
+%D $\rightarrow$ \DVI\ $\rightarrow$ \POSTSCRIPT\ $\rightarrow$
+%D \PDF\ one can insert graphics using specials. In \PDFTEX\
+%D however there is only one step! This means that \PDFTEX\
+%D itself has to do the inclusion.
+%D
+%D At the moment \PDFTEX\ supports inclusion of bitmap \PNG\
+%D graphics as well as not too complicated \PDF\ code. Using
+%D this last option, we are able to include both \METAPOST\ and
+%D \PDF\ output produced by \GHOSTSCRIPT.
+%D
+%D We fall back on the generic \CONTEXT\ module supp-pdf to
+%D accomplish \PDF\ inclusion. The methods implemented there
+%D are hooked into both the figure placement mechanisms of
+%D \CONTEXT\ and the specials inclusion mechanism.

+%D for \METAPOST\ graphics, \type{pdf} for \GHOSTSCRIPT\ \PDF\
+%D code, and \type{png} for bitmap graphics.

+%D \macros
+%D {nextdepth}
+%D {}
+%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}
+%D {}
+%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}
+
+%D \macros
+%D {hsmashbox,vsmashbox}
+%D {}
+%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 \macros
+%D {hsmash,vsmash,
+%D hsmashed,vsmashed}
+%D {}
+%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.
+

+%D Although often needed, \TEX\ does not support arithmics

+%D \dimen0 = \ht0 + \dp0
+%D \stoptypen
+%D
+%D so we implemented:
+%D

+%D \stoptypen
+%D
+%D For instance,
+%D
+%D \starttypen
+%D \getboxheight \dimen0 \of \box0
+%D \getboxheight \someheight \of \box \tempbox
+%D \stoptypen

+%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 \starttypen
+%D \def\getfloat%
+%D {\def\handlefloat{...\box\nextbox...}
+%D \dowithnextbox\handlefloat\vbox}
+%D \stoptypen
+%D
+%D in stead of:
+%D
+%D \starttypen
+%D \def\getfloat#1%
+%D {...#1...}
+%D \stoptypen
+%D
+%D In this implementation the \type{\aftergroup} construction
+%D is needed because \type{\afterassignment} is executed inside
+%D the box.
+
+\newbox\nextbox

+ \afterassignment\dododowithnextbox
+ \setbox\nextbox}
+
+\def\dododowithnextbox%
+ {\aftergroup\dodowithnextbox}
+
+%D So in fact we get:
+%D
+%D \starttypen
+%D \setbox\nextbox { \aftergroup\dodowithnextbox ... }
+%D \stoptypen
+%D
+%D or
+%D
+%D \starttypen
+%D \setbox\nextbox { ... } \dodowithnextbox

+%D ifreshapingbox}
+%D {}
+%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 \starttypen
+%D \beginofshapebox
+%D a piece of text
+%D \endofshapebox
+%D \stoptypen
+%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 \hbox{\llap{\LineNumber\hskip2em}\box\shapebox}}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \haalbuffer
+%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 \hbox
+%D {\llap{\LineNumber\ (\NumberOfLines)\hskip2em}%
+%D \box\shapebox}%
+%D \doglobal\decrement\NumberOfLines}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \haalbuffer
+%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 \hbox{\llap{$\star$\hskip1em}\box\shapebox}%
+%D \doglobal\decrement\NumberOfLines}
+%D
+%D \flushshapebox
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D \haalbuffer
+%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 \starttypen
+%D \ifreshapingbox
+%D \stoptypen
+%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 dohyphenateword}
+%D {}
+%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.
+%D
+%D The simple command \type{\hyphenatedword} accepts one
+%D argument and gives the hyphenated word. This macro calls for
+%D
+%D \starttypen
+%D \dohyphenateword {n} {pre} {word}
+%D \stoptypen
+%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
+%D Here, \type{\hyphenatedword{dohyphenatedword}} is the
+%D shorter alternative for the first line.

+%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 \starttypen
+%D \doboundtext{a very, probably to long, text}{3cm}{...}

+%D \macros
+%D {processisolatedwords}
+%D {}
+%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 \starttypen
+%D The typeset text \in{chapter}[texniques] is for instance
+%D \stoptypen
+%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 \starttypen
+%D \processisolatedwords{some words}\someaction
+%D \stoptypen
+%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 \hbox{$x + y = z$}} \ruledhbox \par
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D which let the words turn up as:
+%D
+%D \startvoorbeeld
+%D \haalbuffer
+%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 \startregels
+%D \haalbuffer
+%D \stopregels
+%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{\hbox}. This enables us to save the
+%D last skip. Next we fill a \type{\vbox} 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 \macros
+%D {sbox}

+%D
+%D This is a rather strange command. It grabs some box content

+%D {centeredbox}
+%D {}
+%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 \starttypen
+%D \vsize=3cm
+%D \hsize=3cm
+%D \ruledvbox to \vsize
+%D {\centeredbox height .5cm width -1cm
+%D {\vrule width \hsize height \vsize}}}
+%D \stoptypen
+%D
+%D Here the \type{\ruledvbox} just shows the surrounding box
+%D and \type{\vrule} is used to show the centered box.
+%D

+%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 surounding box are kept
+%D intact. This commands handles positive and negative
+%D dimensions (which is why we need two boxes with rules).

+%D \macros
+%D {startvboxtohbox,stopvboxtohbox,convertvboxtohbox}
+%D
+%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 \starttypen
+%D \vbox
+%D \bgroup
+%D \startvboxtohbox ... \stopvboxtohbox
+%D \startvboxtohbox ... \stopvboxtohbox
+%D \startvboxtohbox ... \stopvboxtohbox
+%D \egroup
+%D
+%D \vbox
+%D \bgroup
+%D \converthboxtovbox
+%D \egroup
+%D \stoptypen
+%D
+%D These macros are used in reformatting footnotes, so they do
+%D what they're meant for.
+
+\def\setvboxtohbox%
+ {\bgroup
+ \ifdim\baselineskip<16pt \relax
+ \dimen0=\baselineskip
+ \multiply\dimen0 by 1024
+ \else
+ \message{cropping \baselineskip to 16pt}%
+ \baselineskip=\maxdimen
+ \fi
+ \divide\dimen0 by \hsize
+ \multiply\dimen0 by 64
+ \xdef\vboxtohboxfactor{\expandafter\withoutpt\the\dimen0}%
+ \egroup}
+
+\def\startvboxtohbox%
+ {\bgroup
+ \setvboxtohbox
+ \setbox0=\hbox\bgroup}
+
+\def\stopvboxtohbox%
+ {\egroup
+ \dp0=\!!zeropoint
+ \ht0=\vboxtohboxfactor\wd0
+ \box0
+ \egroup}
+
+\def\convertvboxtohbox%
+ {\setvboxtohbox
+ \makehboxofhboxes

+ \noindent\unhbox0\par}
+
+\def\makehboxofhboxes%

+ \repeat}
+
+\def\removehboxes%
+ {\setbox0=\lastbox
+ \ifhbox0
+ {\removehboxes}%
+ \unhbox0
+ \fi}
+
+%D \macros
+%D {doifcontent}
+%D
+%D When processing depends on the availability of content, one
+%D can gove the next macro a try.
+%D
+%D \starttypen
+%D \doifcontent{pre content}{post content}{no content}\somebox
+%D \stoptypen
+%D
+%D Where \type{\somebox} is either a \type{\hbox} or
+%D \type{\vbox}. 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.
+
+\def\doifcontent#1#2#3%
+ {\dowithnextbox
+ {\ifhbox\nextbox
+ \ifdim\wd\nextbox>\!!zeropoint
+ #1\unhbox\nextbox#2\relax
+ \else
+ #3\relax
+ \fi
+ \else
+ \ifdim\ht\nextbox>\!!zeropoint
+ #1\unvbox\nextbox#2\relax
+ \else
+ #3\relax
+ \fi
+ \fi}}
+
+%D So when we say:
+%D
+%D \startbuffer
+%D \doifcontent{[}{]}{}\hbox{content sensitive typesetting}
+%D
+%D \doifcontent{}{\pagina}{}\vbox{content sensitive typesetting}
+%D
+%D \doifcontent{}{}{\message{Didn't you forget something?}}\hbox{}
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D We get:
+%D
+%D \haalbuffer
+%D
+%D Where the last call of course does not show up in this
+%D document, but definitely generates a confusing message.
+
+% maybe some day we need this
+%
+% \def\appendvbox#1% % uses \box8
+% {\bgroup
+% \ifdim\prevdepth<\!!zeropoint
+% \ifdim\pagetotal=\!!zeropoint
+% \setbox8=\vtop{\unvcopy#1}%

+%D \TEX\ operates on files, so one wouldn't wonder that there
+%D is a separate module for file support. In \CONTEXT\ files
+%D are used for several purposes:
+%D
+%D \startopsomming[opelkaar]
+%D \som general textual input
+%D \som logging status information
+%D \som saving registers, lists and references
+%D \som buffering defered textual input
+%D \stopopsomming
+%D
+%D When dealing with files we can load them as a whole, using
+%D the \type{\input} primitive or load them on a line||by||line
+%D basis, using \type{\read}. Writing is always done line by
+%D line, using \type{\write}.
+
+\writestatus{loading}{Context Support Macros / Files}
+
+\unprotect
+
+%D \macros
+%D {pushendofline,popendofline}
+%D {}
+%D
+%D When we are loading files in the middle of the typesetting
+%D process, for instance when we load references, we have to be
+%D sure that the reading process does not generate so called
+%D 'spurious spaces'. This can be prevented by assigning the
+%D line ending character the \CATCODE\ comment. This is
+%D accomplished by
+%D
+%D \starttypen
+%D \pushendofline
+%D ... reading ...
+%D \popendofline
+%D \stoptypen
+%D
+%D Just to be sure, we save the current meaning of \type{^^M}
+%D in \type{\poppedendofline}.
+

+\def\popendofline

+
+%D \macros
+%D {scratchread, scratchwrite}
+%D {}
+%D
+%D We define a scratch file for reading. Keep in mind that
+%D the number of files is limited to~16, so use this one when
+%D possible. We also define a scratch output file.
+
+\newread \scratchread
+\newwrite \scratchwrite
+
+%D \macros

+%D
+%D The next macro offers a framework for processing files on a
+%D line by line basis.
+%D
+%D \starttypen
+%D \processfile \identifier {name} \action
+%D \stoptypen
+%D
+%D The first argument can for instance be \type{\scratchread}.
+%D The action must do something with \type{\fileline}, which
+%D holds the current line.

+%D \macros
+%D {readfile,ReadFile,maxreadlevel,
+%D normalinput}
+%D {}
+%D
+%D One cannot be sure if a file exists. When no file can be
+%D found, the \type{\input} primitive gives an error message
+%D and switches to interactive mode. The macro \type{\readfile}
+%D takes care of non||existing files. This macro has two faces.
+%D
+%D \starttypen
+%D \ReadFile {filename}
+%D \readfile {filename} {before loading} {not found}
+%D \stoptypen
+%D
+%D Many \TEX\ implementations have laid out some strategy for
+%D locating files. This can lead to unexpected results,
+%D especially when one loads files that are not found in the
+%D current directory. Let's give an example of this. In
+%D \CONTEXT\ illustrations can be defined in an external file.
+%D The resizing macro first looks if an illustration is defined
+%D in the local definitions file. When no such file is found,
+%D it searches for a global file and when this file is not
+%D found either, the illustration itself is scanned for
+%D dimensions. One can imagine what happens if an adapted,
+%D localy stored illustration, is scaled according to
+%D dimensions stored somewhere else.
+%D
+%D When some \TEX\ implementation starts looking for a file, it
+%D normally first looks in the current directory. When no file
+%D is found, \TEX\ starts searching on the path where format
+%D and/or style files are stored. Depending on the implementation
+%D this can considerably slow down processing speed.
+%D
+%D In \CONTEXT, we support a project||wise ordening of files.
+%D In such an approach it seems feasible to store common files
+%D in a lower directory. When for instance searching for a
+%D general layout file, we therefore have to backtrack.
+%D
+%D These three considerations have lead to a more advanced
+%D approach for loading files.
+%D
+%D We first present an earlier implementation of
+%D \type{\readfile}. This command backtracks parent
+%D directories, upto a predefined level. Users can change this
+%D level, but we default to~3.
+%D
+%D \starttypen
+%D \def\maxreadlevel {3}
+%D \stoptypen
+%D
+%D This is a pseudo \COUNTER.
+%D
+%D We use \type{\normalinput} instead of \type{\input}
+%D because we want to be able to redefine the original
+%D \type{\input} when needed, for instance when loading third
+%D party libraries.
+
+\let\normalinput=\input
+
+\def\maxreadlevel {3}
+
+\def\doreadfile#1#2#3%
+ {\immediate\openin\scratchread=#1\relax
+ \ifeof\scratchread
+ \immediate\closein\scratchread
+ \decrement\readlevel
+ \ifnum\readlevel>0\relax
+ \doreadfile{\f!parentpath/#1}{#2}{#3}%
+ \else
+ #3%
+ \fi
+ \else
+ \immediate\closein\scratchread
+ #2%
+ \normalinput #1\relax
+ \fi}
+
+\def\readfile#1%
+ {\let\readlevel=\maxreadlevel
+ \doreadfile{#1}}
+
+\def\ReadFile#1%
+ {\readfile{#1}{}{}}
+
+%D \macros
+%D {readjobfile,readlocfile,readsysfile,readfixfile}
+%D {}
+%D
+%D This implementation honnors the third situation, but we
+%D still can get unwanted files loaded and/or can get involved
+%D in extensive searching.
+%D
+%D Due to different needs, we decided to offer four alternative
+%D loading commands. With \type{\readjobfile} we load a local
+%D file and do no backtracking, while \type{\readlocfile}
+%D backtracks~\readlevel\ directories, including the current
+%D one.
+
+\def\readjobfile#1%
+ {\newcounter\readlevel
+ \doreadfile{\f!currentpath/#1}}
+
+\def\readlocfile#1%
+ {\let\readlevel=\maxreadlevel
+ \doreadfile{\f!currentpath/#1}}
+
+%D System files can be anywhere and therefore
+%D \type{\readsysfile} is not bound to the current directory
+%D and obeys the \TEX\ implementation.
+
+\def\readsysfile#1%
+ {\let\readlevel=\maxreadlevel
+ \doreadfile{#1}}
+
+%D The last one, \type{\readfixfile} searches on the directory
+%D specified and backtracks too.
+
+\def\readfixfile#1#2%
+ {\let\readlevel=\maxreadlevel
+ \doreadfile{#1/#2}}
+
+%D After having defined this commands, we reconsidered the
+%D previously defined \type{\readfile}. This time we more or
+%D less impose the search order.
+
+\def\readfile#1#2#3%
+ {\readlocfile{#1}{#2}
+ {\readjobfile{#1}{#2}
+ {\readsysfile{#1}{#2}{#3}}}}
+
+%D So now we've got ourselves five file loading commands:
+%D
+%D \starttypen
+%D \readfile {filename} {before loading} {not found}
+%D
+%D \readjobfile {filename} {before loading} {not found}
+%D \readlocfile {filename} {before loading} {not found}
+%D \readfixfile {filename} {before loading} {not found}
+%D \readsysfile {directory} {filename} {before loading} {not found}
+%D \stoptypen
+
+%D \macros
+%D {readjobfile,readlocfile,readsysfile,readfixfile}
+%D {}
+%D
+%D The next four alternatives can be used for opening files
+%D for reading on a line||by||line basis. These commands get
+%D an extra argument, the filetag. Explicit closing is done
+%D in the normal way by \type{\closein}.
+
+\def\doopenin#1#2%
+ {\increment\readlevel
+ \immediate\openin#1=#2\relax
+ \ifeof#1\relax
+ \ifnum\readlevel>\maxreadlevel\relax
+ \else
+ \immediate\closein#1\relax
+ \doopenin{#1}{\f!parentpath/#2}%
+ \fi
+ \fi}
+
+\def\openjobin#1#2%
+ {\newcounter\readlevel
+ \doopenin{#1}{\f!currentpath/#2}}
+
+\def\opensysin#1#2%
+ {\let\readlevel=\maxreadlevel
+ \doopenin{#1}{#2}}
+
+\def\openlocin#1#2%
+ {\let\readlevel=\maxreadlevel
+ \doopenin{#1}{\f!currentpath/#2}}
+
+\def\openfixin#1#2#3%
+ {\let\readlevel=\maxreadlevel
+ \doopenin{#1}{#2/#3}}
+
+%D \macros
+%D {doiffileelse,doiflocfileelse}
+%D {}
+%D
+%D The next alternative only looks if a file is present. No
+%D loading is done. This one obeys the standard \TEX\
+%D implementation method.
+%D
+%D \starttypen
+%D \doiffileelse {filename} {before loading} {not found}
+%D \stoptypen
+%D
+%D We use \type{\next} here, because we want to close the
+%D file first. We also provide the local alternative:
+%D
+%D \starttypen
+%D \doiflocfileelse {filename} {before loading} {not found}
+%D \stoptypen
+
+\def\doiffileelse#1#2#3%
+ {\immediate\openin\scratchread=#1\relax
+ \ifeof\scratchread
+ \def\next{#3}%
+ \else
+ \def\next{#2}%
+ \fi
+ \immediate\closein\scratchread
+ \next}
+
+\def\doiflocfileelse#1%
+ {\doiffileelse{\f!currentpath/#1}}
+
+%D \macros
+%D {doinputonce}
+%D {}
+%D
+%D Especially macropackages need only be loaded once.
+%D Repetitive loading not only costs time, relocating registers
+%D often leads to abortion of the processing because \TEX's
+%D capacity is limited. One can prevent multiple loading by
+%D using:
+%D
+%D \starttypen
+%D \doloadonce{filename}
+%D \stoptypen
+%D
+%D This command obeys the standard method for locating files.
+
+\def\doinputonce#1%
+ {\doifundefined{@@@#1@@@}%
+ {\setgvalue{@@@#1@@@}{}%
+ \doiffileelse{#1}{\normalinput #1}{}}}
+
+%D \macros
+%D {doifparentfileelse}
+%D {}
+%D
+%D The test \type{\doifelse{\jobname}{filename}} does not give
+%D the desired result, simply because \type{\jobname} expands
+%D to characters with \CATCODE~12, while the characters in
+%D \type{filename} have \CATCODE~11. So we can better use:
+%D
+%D \starttypen
+%D \doifparentfileelse{filename}{yes}{no}
+%D \stoptypen
+
+\def\doifparentfileelse#1#2#3%
+ {\edef\!!stringa{#1}%
+ \@EA\convertargument\!!stringa\to\!!stringa
+ \@EA\def\@EA\!!stringb\@EA{\jobname}%

+%D One of \TEX's strong points in building paragraphs is the way
+%D hyphenations are handled. Although for real good hyphenation
+%D of non||english languages some extensions to the program are
+%D needed, fairly good results can be reached with the standard
+%D mechanisms and an additional macro, at least in Dutch.
+
+\unprotect
+
+%D \CONTEXT\ originates in the wish to typeset educational
+%D materials, especially in a technical environment. In
+%D production oriented environments, a lot of compound words
+%D are used. Because the Dutch language poses no limits on
+%D combining words, we often favor putting dashes between those
+%D words, because it facilitates reading, at least for those
+%D who are not that accustomed to it.
+%D
+%D In \TEX\ compound words, separated by a hyphen, are not
+%D hyphenated at all. In spite of the multiple pass paragraph
+%D typesetting this can lead to parts of words sticking into
+%D the margin. The solution lays in saying
+%D \type{spoelwater||terugwinunit} instead of
+%D \type{spoelwater-terugwinunit}. By using a one character
+%D command like \type{|}, delimited by the same character
+%D \type{|}, we get ourselves both a decent visualization (in
+%D \TEXEDIT\ and colored verbatim we color these commands
+%D yellow) and an efficient way of combining words.
+%D
+%D The sequence \type{||} simply leads to two words connected by
+%D a hyphen. Because we want to distinguish such a hyphen from
+%D the one inserted when \TEX\ hyphenates a word, we use a bit
+%D longer one.
+%D
+%D \hyphenation {spoel-wa-ter te-rug-win-unit}
+%D
+%D \starttest
+%D \test {spoelwater||terugwinunit}
+%D \stoptest
+%D
+%D As we already said, the \type{|} is a command. This commands
+%D accepts an optional argument before it's delimiter, which is
+%D also a \type{|}.
+%D
+%D \hyphenation {po-ly-meer che-mie}
+%D
+%D \starttest
+%D \test {polymeer|*|chemie}
+%D \stoptest
+%D
+%D Arguments like \type{*} are not interpreted and inserted
+%D directly, in contrary to arguments like:
+%D
+%D \starttest
+%D \test {polymeer|~|chemie}
+%D \test {|(|polymeer|)|chemie}
+%D \test {polymeer|(|chemie|)| }
+%D \stoptest
+%D
+%D Although such situations seldom occur |<|we typeset thousands
+%D of pages before we encountered one that forced us to enhance
+%D this mechanism|>| we also have to take care of comma's.
+%D
+%D \hyphenation {uit-stel-len}
+%D
+%D \starttest
+%D \test {op||, in|| en uitstellen}
+%D \stoptest
+%D
+%D The next special case (concerning quotes) was brought to my
+%D attention by Piet Tutelaers, one of the driving forces
+%D behind rebuilding hyphenation patterns for the dutch
+%D language.\voetnoot{In 1996 the spelling of the dutch
+%D language has been slightly reformed which made this topic
+%D actual again.} We'll also take care of this case.
+%D
+%D \starttest
+%D \test {AOW|'|er}
+%D \test {cd|'|tje}
+%D \test {ex|-|PTT|'|er}
+%D \test {rock|-|'n|-|roller}
+%D \stoptest
+%D
+%D Tobias Burnus pointed out that I should also support
+%D something like
+%D
+%D \starttest
+%D \test {well|_|known}
+%D \stoptest
+%D
+%D to strees the compoundness of hyphenated words.
+%D
+%D Of course we also have to take care of the special case:
+%D
+%D \starttest
+%D \test {text||color and ||font}
+%D \stoptest
+
+%D \macros
+%D {installdiscretionaries}
+%D {}
+%D
+%D The mechanism described here is one of the older inner parts
+%D of \CONTEXT. The most recent extensions concerns some
+%D special cases as well as the possibility to install other
+%D characters as delimiters. The prefered way of specifying
+%D compound words is using \type{||}, which is installed by:
+%D
+%D \starttypen
+%D \installdiscretionaries || -
+%D \stoptypen
+%D
+%D Some alternative definitions are:
+%D
+%D \startbuffer
+%D \installdiscretionaries ** -
+%D \installdiscretionaries ++ -
+%D \installdiscretionaries // -
+%D \installdiscretionaries ~~ -
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D after which we can say:
+%D
+%D \bgroup
+%D \haalbuffer
+%D \starttest
+%D \test {test**test**test}
+%D \test {test++test++test}
+%D \test {test//test//test}
+%D \test {test~~test~~test}
+%D \stoptest
+%D \egroup
+
+%D \macros
+%D {compoundhyphen,
+%D beginofsubsentence,endofsubsentence}
+%D {}
+%D
+%D Now let's go to the macros. First we define some variables.
+%D In the main \CONTEXT\ modules these can be tuned by a setup
+%D command. Watch the (maybe) better looking compound hyphen.
+
+\def\compoundhyphen {{-}\kern-.25ex{-}}
+\def\beginofsubsentence {---}
+\def\endofsubsentence {---}
+
+%D The last two variables are needed for subsentences
+%D |<|like this one|>| which we did not yet mention.
+%D
+%D We want to enable breaking but at the same time don't want
+%D compound characters like |-| or || to be separated from the
+%D words. \TEX\ hackers will recognise the next two macro's:
+
+\def\prewordbreak {\penalty10000\hskip0pt\relax}
+\def\postwordbreak {\penalty0\prewordbreak}
+
+%D We first show the original implementation, which only
+%D supports \type{|} as command and delimiter. Before
+%D activating \type{|} we save it's value:
+%D
+%D \starttypen
+%D \edef\domathmodediscretionary{\string|}
+%D \stoptypen
+%D
+%D after which we're ready to define it's meaning to:
+%D
+%D \starttypen
+%D \catcode`\|=\@@active
+%D
+%D \unexpanded\def|%
+%D {\ifmmode
+%D \expandafter\domathmodediscretionary
+%D \else
+%D \expandafter\dotextmodediscretionary
+%D \fi}
+%D \stoptypen
+%D
+%D We need a two stage \type{\futurelet} because we want to
+%D look ahead for both the compound character definition and
+%D the (optional) comma that follows it, and because we want to
+%D prevent that \TEX\ puts this comma on the next line. We use
+%D \type{\next} for easy and fast checking of the argument, we
+%D save this argument (which can consist of more tokens) and
+%D also save the character following the \type{|#1|} in
+%D \type{\nextnext}.
+%D
+%D \starttypen
+%D \def\dotextmodediscretionary%
+%D {\bgroup
+%D \futurelet\next\dodotextmodediscretionary}
+%D
+%D \def\dodotextmodediscretionary#1|%
+%D {\def\betweendiscretionaries{#1}%
+%D \futurelet\nextnext\dododotextmodediscretionary}
+%D \stoptypen
+%D
+%D The main macro consists of quite some \type{\ifx} tests
+%D while \type{\checkafterdiscretionary} handles the commas.
+%D We show the simplified version here:
+%D
+%D \starttypen
+%D \def\dododotextmodediscretionary%
+%D {\let\nextnextnext=\egroup
+%D \ifx |\next
+%D \checkafterdiscretionary
+%D \prewordbreak\hbox{\compoundhyphen\nextnext}\allowbreak
+%D \else\ifx=\next
+%D \prewordbreak\compoundhyphen
+%D \else\ifx~\next
+%D \discretionary{-}{}{\thinspace}\postwordbreak
+%D \else\ifx(\next
+%D \prewordbreak\discretionary{}{(-}{(}\prewordbreak
+%D \else\ifx)\next
+%D \prewordbreak\discretionary{-)}{}{)}\prewordbreak
+%D \else\ifx'\next
+%D \prewordbreak\discretionary{-}{}{'}\postwordbreak
+%D \else
+%D \checkafterdiscretionary
+%D \prewordbreak\hbox{\betweendiscretionaries\nextnext}\allowbreak
+%D \fi\fi\fi\fi\fi\fi
+%D \nextnextnext}
+%D
+%D \def\checkafterdiscretionary%
+%D {\ifx,\nextnext
+%D \def\nextnextnext{\afterassignment\egroup\let\next=}%
+%D \else
+%D \let\nextnext=\relax
+%D \fi}
+%D \stoptypen
+%D
+%D Handling \type{(} and \type{)} is a a bit special, because
+%D \TEX\ sees them as decent hyphenation points, according to
+%D their \type{\lccode} being non||zero. For the same reason,
+%D later on in this module we cannot manipulate the
+%D \type{\lccode} but take the \type{\uccode}.
+
+%D The most recent implementation is more advanced. As
+%D demonstrated we can install delimiters, like:
+%D
+%D \starttypen
+%D \installdiscretionaries || \compoundhyphen
+%D \stoptypen
+%D
+%D This time we have to use a bit more clever way of saving the
+%D math mode specification of the character we're going to
+%D make active. We also save the user supplied compound hyphen.
+%D We show the a bit more traditional implementation first.
+%D
+%D \starttypen
+%D \def\installdiscretionaries#1%
+%D {\catcode`#1\@@other
+%D \expandafter\doinstalldiscretionaries\string#1}
+%D
+%D \def\doinstalldiscretionaries#1%
+%D {\setvalue{mathmodediscretionary#1}{#1}%
+%D \catcode`#1\@@active
+%D \dodoinstalldiscretionaries}
+%D
+%D \def\dodoinstalldiscretionaries#1#2%
+%D {\setvalue{textmodediscretionary\string#1}{#2}%
+%D \unexpanded\def#1{\discretionarycommand#1}}
+%D \stoptypen
+%D
+%D A bit more \CATCODE\ and character trickery enables us to
+%D discard the two intermediate steps. This trick originates
+%D on page~394 of the \TEX book, in the appendix full of
+%D dirty tricks. The second argument has now become redundant,
+%D but I decided to reserve it for future use. At least it
+%D remembers us of the symmetry.
+
+\def\installdiscretionaries#1#2#3%
+ {\setvalue{mathmodediscretionary\string#1}{\char`#1}%
+ \setvalue{textmodediscretionary\string#1}{#3}%
+ \catcode`#1=\@@active
+ \scratchcounter=\the\uccode`~
+ \uccode`~=`#1
+ \uppercase{\unexpanded\def~{\discretionarycommand~}}%
+ \uccode`~=\scratchcounter}
+
+\def\dohandlemathmodebar#1%
+ {\getvalue{mathmodediscretionary\string#1}}
+
+\def\discretionarycommand%
+ {\ifmmode
+ \expandafter\dohandlemathmodebar
+ \else
+ \expandafter\dotextmodediscretionary
+ \fi}
+
+%D Although adapting character codes and making characters
+%D active can interfere with other features of macropackages,
+%D normally there should be no problems with things like:
+%D
+%D \starttypen
+%D \installdiscretionary || +
+%D \installdiscretionary ++ =
+%D \stoptypen
+%D
+%D The real work is done by the next set of macros. We have
+%D to use a double \type{\futurelet} because we have to take
+%D following characters into account.
+
+\def\dotextmodediscretionary#1%

+
+%D The macro \type{\checkbeforediscretionary} takes care of
+%D loners like \type{||word}, while it counterpart
+%D \type{\checkafterdiscretionary} is responsible for handling
+%D the comma.
+
+%D \macros
+%D {beginofsubsentencespacing,endofsubsentencespacing}
+%D {}
+%D
+%D In the previous macros we provided two hooks which can be
+%D used to support nested sub||sentences. In \CONTEXT\ these
+%D hooks are used to insert a small space when needed.
+
+\let\beginofsubsentencespacing=\relax
+\let\endofsubsentencespacing =\relax
+
+%D Before we show some more tricky alternative, we first install
+%D the mechanism:
+
+\installdiscretionaries || \compoundhyphen
+
+%D One of the drawbacks of this mechanism is that characters can
+%D be made active afterwards. The next alternative can be used
+%D in such situations. This time we don't compare the arguments
+%D directly but use the \type{\uccode}'s instead. \TEX\
+%D initializes these codes of the alphabetics glyphs to their
+%D uppercase counterparts. Normally the other characters remain
+%D zero. If so, we can use the \type{\uccode} as a signal.
+
+%D \macros
+%D {enableactivediscretionaries}
+%D {}
+%D
+%D The more advanced mechanism is activated by calling:
+%D
+%D \starttypen
+%D \enableactivediscretionaries
+%D \stoptypen
+%D
+%D which is defined as:
+
+\def\enableactivediscretionaries%
+ {\uccode`'=`'\relax \uccode`~=`~\relax \uccode`_=`_\relax
+ \uccode`(=`(\relax \uccode`)=`)\relax \uccode`==`=\relax
+ \uccode`<=`<\relax \uccode`>=`>\relax
+ \let\dotextmodediscretionary = \activedotextmodediscretionary
+ \let\dododotextmodediscretionary = \activedododotextmodediscretionary}
+
+%D We only have to redefine two macros. While saving the
+%D \type{\uccode} in a macro we have to take care of empty
+%D arguments, like in \type{||}.
+
+\def\activedotextmodediscretionary#1%
+ {\bgroup
+ \def\dodotextmodediscretionary##1#1%
+ {\def\betweendiscretionary{##1}%
+ \def\nextuccode####1####2\relax%
+ {\ifcat\noexpand####1\noexpand\relax
+ \edef\nextuccode{0}%
+ \else
+ \edef\nextuccode{\the\uccode`####1}%
+ \fi}%
+ \nextuccode##1@\relax
+ \futurelet\nextnext\dododotextmodediscretionary}%
+ \let\discretionarycommand=#1%
+ \def\textmodediscretionary{\getvalue{textmodediscretionary\string#1}}%
+ \futurelet\next\dodotextmodediscretionary}
+
+%D This time we use \type{\ifnum}:
+
+\def\activedododotextmodediscretionary%
+ {\let\nextnextnext=\egroup
+ \ifx\discretionarycommand\next
+ \checkafterdiscretionary
+ \bgroup

+ \nextnextnext}
+
+%D Now we can safely do things like: \enableactivediscretionaries
+%D
+%D \starttypen
+%D \catcode`<=\@@active \def<{hello there}
+%D \catcode`>=\@@active \def>{hello there}
+%D \catcode`(=\@@active \def({hello there}
+%D \catcode`)=\@@active \def){hello there}
+%D \stoptypen
+%D
+%D In normal day||to||day production of texts this kind of
+%D activation is seldom used.\voetnoot{In the \CONTEXT\ manual
+%D the \type{<} and \type{>} are made active and used for some
+%D cross||reference trickery.} If so, we have to take care of
+%D the math mode explicitly, just like we did when making
+%D \type{|} active. It can be confusing too, especially when we
+%D load macropackages afterwards that make use of \type{<} in
+%D \type{\ifnum} or \type{\ifdim} statements.
+
+%D \macros
+%D {installcompoundcharacter}
+%D {}
+%D
+%D When Tobias Burnus started translating the dutch manual of
+%D \PPCHTEX\ into german, he suggested to let \CONTEXT\ support
+%D the \type{german.sty} method of handling compound
+%D characters, especially the umlaut. This package is meant for
+%D use with \PLAIN\ \TEX\ as well as \LATEX.
+%D
+%D I decided to implement compound character support as
+%D versatile as possible. As a result one can define his own
+%D compound character support, like:
+%D
+%D \starttypen
+%D \installcompoundcharacter "a {\"a}
+%D \installcompoundcharacter "e {\"e}
+%D \installcompoundcharacter "i {\"i}
+%D \installcompoundcharacter "u {\"u}
+%D \installcompoundcharacter "o {\"o}
+%D \installcompoundcharacter "s {\SS}
+%D \stoptypen
+%D
+%D or even
+%D
+%D \starttypen
+%D \installcompoundcharacter "ck {\discretionary {k-}{k}{ck}}
+%D \installcompoundcharacter "ff {\discretionary{ff-}{f}{ff}}
+%D \stoptypen
+%D
+%D The support is not limited to alphabetic characters, so the
+%D next definition is also valid.
+%D
+%D \starttypen
+%D \installcompoundcharacter ". {.\doifnextcharelse{\spacetoken}{}{\kern.125em}}
+%D \stoptypen
+%D
+%D The implementation looks familiar and uses the same tricks as
+%D mentioned earlier in this module. We take care of two
+%D arguments, which complicates things a bit.
+
+\def\@nc@{@nc@} % normal character
+\def\@cc@{@cc@} % compound character
+\def\@cs@{@cs@} % compound characters
+
+\def\installcompoundcharacter #1#2#3 #4%
+ {\setvalue{\@nc@\string#1}{\char`#1}%
+ \def\!!stringa{#3}%
+ \ifx\!!stringa\empty
+ \setvalue{\@cc@\string#1\string#2}{#4}%
+ \else
+ \setvalue{\@cs@\string#1\string#2\string#3}{#4}%
+ \fi
+ \catcode`#1=\@@active
+ \scratchcounter=\the\uccode`~
+ \uccode`~=`#1
+ \uppercase{\unexpanded\def~{\handlecompoundcharacter~}}%
+ \uccode`~=\scratchcounter}
+
+%D In handling the compound characters we have to take care of
+%D \type{\bgroup} and \type{\egroup} tokens, so we end up with
+%D a multi||step interpretation macro. We look ahead for a
+%D \type{\bgroup}, \type{\egroup} or \type{\blankspace}. Being
+%D no user of this mechanism, the credits for testing them goes
+%D to Tobias Burnus, the first german user of \CONTEXT.
+%D
+%D We define these macros as \type{\long} because we can
+%D expect \type{\par} tokens. We need to look into the future
+%D with \type{\futurelet} to prevent spaces from
+%D disappearing.
+
+\def\handlecompoundcharacter#1%
+ {\def\dohandlecompoundcharacter%
+ {\ifx\next\bgroup
+ %\def\next{\dodohandlecompoundcharacter#1}% % handle "{ee} -> \"ee

+ \else\ifx\next\egroup

+ \fi\fi\fi
+ \next}%
+ \futurelet\next\dododohandlecompoundcharacter}
+
+%D Besides taken care of the grouping and space tokens, we have
+%D to deal with three situations. First we look if the next
+%D character equals the first one, if so, then we just insert
+%D the original. Next we look if indeed a compound character is
+%D defined. We either execute the compound character or just
+%D insert the first. So we have
+%D
+%D \starttypen
+%D <key><key> <key><known> <key><unknown>
+%D \stoptypen
+%D
+%D In later modules we will see how these commands are used.

+%D \macros

+%D If needed, one can add a discretionary hyphen using \type

+% E-tex : a primitive that tells us that \write18 works
+% E-tex : \executeMetaPost filename
+% ConTeXt : automatic flush at end of job
+
+%D \METAPOST\ is John Hobbys alternative for \METAFONT\ and
+%D produces superior \POSTSCRIPT\ code. In this module we
+%D integrate \METAPOST\ support int \CONTEXT. We offer two
+%D tracks:
+%D
+%D \startopsomming
+%D \som generating \METAPOST\ code, running this program from
+%D within \TEX\ using \type{\write18}, and importing the
+%D result
+%D \som generating \METAPOST\ code, processing the code
+%D afterward, and importing the result in a second pass
+%D \stopopsomming
+%D
+%D The first approach uses a non standard \TEX\ feature,
+%D implemented in Web2c. I'm not going to discuss the pros and
+%D cons of running programs from within others, but all
+%D arguments against this can be overcome by implementing a
+%D \TEX\ worthy primitive:
+%D
+%D \starttypen
+%D \excuteMetaPost filename
+%D \stoptypen
+%D
+%D Ok then, let's start:
+
+\writestatus{loading}{Context Support Macros / MetaPost Inclusion}
+
+\unprotect
+
+%D \macros
+%D {startMPgraphic}
+%D
+%D From within \TEX\ one can execute \METAPOST\ code by putting
+%D it between the two commands
+%D
+%D \starttypen
+%D \startMPgraphic
+%D \stopMPgraphic
+%D \stoptypen
+%D
+%D This is implemented as:
+
+\def\startMPgraphic#1\stopMPgraphic%
+ {\startwritingMPgraphic
+ \writeMPgraphic{#1}%
+ \stopwritingMPgraphic}
+
+%D \macros
+%D {startwritingMPgraphic,
+%D writeMPgraphic,
+%D stopwritingMPgraphic}
+%D
+%D If the writing process is divided into more steps, one can
+%D use the components of this macro directly.
+%D
+%D \starttypen
+%D \startwritingMPgraphic
+%D ...
+%D \writeMPgraphic{...}
+%D ...
+%D \writeMPgraphic{...}
+%D ...
+%D \stopwritingMPgraphic
+%D \stoptypen
+
+%D \macros
+%D {ifrunMPgraphics}
+%D
+%D These macros look a bit more complicated that one would
+%D expect at first sight. This is due to the two ways of
+%D processing these graphics, mentioned in a previous
+%D paragraph. Which method is used, the direct or indirect
+%D one, depends on a boolean.
+
+\newif\ifrunMPgraphics
+
+%D If set to true, one can do with a single pass, else one must
+%D process the \METAPOST\ file \type{mpgraph} between two
+%D succesive \TEX\ runs.
+
+\def\MPgraphicfile{mpgraph}
+
+%D When we run \METAPOST\ from within \TEX, each graphic is
+%D processed at once, which means that we reuse this file many
+%D times. When however the execution is delayed, all graphics
+%D are saved in a separate figure. The current graphic is
+%D characterized bij a number:
+
+\newcounter\currentMPgraphic
+
+%D \macros
+%D {ifreuseMPgraphics}
+%D
+%D If one want to reuse grapics, one can save much redundant
+%D run time by setting the next switch to true.
+
+\newif\ifreuseMPgraphics
+
+%D The three macros responsible for writing the graphic
+%D implement both schemes.
+
+%D \macro
+%D {MPinclusions}
+%D
+%D One can include for instance common input commands by
+%D assigning those to the token register:
+
+\newtoks\MPinclusions
+
+\def\writeMPgraphic%
+ {\immediate\write\scratchwrite}
+
+\def\startwritingMPgraphic%
+ {\ifrunMPgraphics
+ \ifreuseMPgraphics \else
+ \doglobal\newcounter\currentMPgraphic
+ \fi
+ \doglobal\increment\currentMPgraphic
+ \immediate\openout\scratchwrite=\MPgraphicfile.mp
+ \immediate\write\scratchwrite{\the\MPinclusions}%
+ \else
+ \doglobal\increment\currentMPgraphic
+ \ifnum\currentMPgraphic=1
+ \immediate\openout\scratchwrite=\MPgraphicfile.mp
+ \immediate\write\scratchwrite{\the\MPinclusions}%
+ \fi
+ \fi
+ \immediate\write\scratchwrite{beginfig(\currentMPgraphic);}%
+ \global\let\flushMPgraphics\dodostopwritingMPgraphic
+ \global\let\stopwritingMPgraphic=\dostopwritingMPgraphic}
+
+\def\dostopwritingMPgraphic%
+ {\immediate\write\scratchwrite{endfig;}%
+ \ifrunMPgraphics
+ \dodostopwritingMPgraphic
+ \fi}
+
+\def\dodostopwritingMPgraphic%
+ {\ifnum\currentMPgraphic>0
+ \immediate\write\scratchwrite{end.}%
+ \immediate\closeout\scratchwrite
+ \runMPgraphic{\MPgraphicfile}%
+ \fi
+ \global\let\flushMPgraphics=\relax}
+
+\let\stopwritingMPgraphic=\relax
+\let\flushMPgraphics =\relax
+
+%D \macros
+%D {flushMPgraphics}
+%D
+%D When we use the indirect method, all graphics are saved in
+%D one file. This means that we cannot close this file after
+%D every \type{\stopMPgraphic}. Therefore we need to say:
+%D
+%D \starttypen
+%D \flushMPgraphic
+%D \stoptypen
+%D
+%D else the file is closed without writing the \METAPOST\ end
+%D command. One will notice this fast enough when in indirect
+%D mode. When using the direct mode this command is not
+%D implicitly needed, but ommiting it makes files less
+%D portable.
+
+%D \macros
+%D {loadcurrentMPgraphic,
+%D placeMPgraphic}
+%D
+%D Once defined, we can call for this graphic by saying:
+%D
+%D \starttypen
+%D \loadcurrentMPgraphic{setups}
+%D \placeMPgraphic
+%D \stoptypen
+%D
+%D This two stage insert permits some intermediate manipulations
+%D of the graphic, which temporary saved in:
+
+\newbox\MPgraphic
+
+\def\loadcurrentMPgraphic#1%
+ {\loadMPgraphic{\MPgraphicfile.\currentMPgraphic}{#1}}
+
+\def\loadMPgraphic#1#2%
+ {\setbox\MPgraphic=\hbox{\insertMPfile{#1}{#2}}}
+
+\def\placeMPgraphic%
+ {\box\MPgraphic}
+
+%D \macros
+%D {startreusableMPgraphic, reuseMPgraphic, useMPbox}
+%D
+%D One can use the next macro for defining graphics that are
+%D to be reused. When the next switch is set, graphics are
+%D cached.
+
+\newif\ifuseMPbox % nog eens cyclische buffer
+
+\long\def\startreusableMPgraphic#1#2\stopreusableMPgraphic%
+ {\reuseMPgraphicstrue
+ \doifundefined{MP:#1}

+ \noexpand\placeMPgraphic}%
+ \fi}}
+
+\def\reuseMPgraphic#1%
+ {\getvalue{MP:#1}}
+
+%D \macro
+%D {startuseMPgraphic,useMPgraphic}
+%D
+%D The every||time||it's||used original one is defined below.
+%D This one makes sense when the graphic uses random numbers.
+
+\def\startuseMPgraphic#1#2\stopuseMPgraphic%
+ {\reuseMPgraphicstrue
+ \long\setvalue{MP:#1}%
+ {\startMPgraphic#2\stopMPgraphic
+ \loadcurrentMPgraphic{}%
+ \placeMPgraphic}}
+
+\let\useMPgraphic=\reuseMPgraphic
+
+%D We didn't yet define the macro responsible for processing
+%D the graphic from within \TEX.
+
+\def\runMPgraphic#1%
+ {\ifrunMPgraphics
+ \executeMETAPOST{#1}%
+ \else
+ \message{[flush and process \MPgraphicfile.mp afterwards]}%
+ \fi}
+
+%D \macros
+%D {executeMetaPost, executeMETAPOST, executesystemcommand}
+%D
+%D With \type{\executeMETAPOST} being defined as:
+
+\ifx\undefined\executeMetaPost
+ \def\executeMETAPOST#1{\executesystemcommand{\executeMetaPost{#1}}}
+\fi
+
+%D There are two system dependant definitions:
+
+\ifx\undefined\executesystemcommand
+ \def\executesystemcommand#1{\immediate\write18{#1}}
+\fi
+
+\ifx\undefined\executeMetaPost
+ \def\executeMetaPost#1{mpost #1}
+\fi
+
+%D \macros
+%D {insertMPfile}
+%D
+%D One can define this command in advance or redefine it after
+%D loading this module. The same goes for the forward
+%D reference to the figure loading macro:
+
+\ifx\undefined\insertMPfile
+
+ \def\insertMPfile#1#2%
+ {\ifx\undefined\externalfigure
+ \message{[insert file #1 here]}%
+ \else
+ \externalfigure[#1][\c!type=eps,\c!methode=mps,#2]%
+ \fi}
+
+\fi
+
+%D This macro takes {\em two} arguments, the second one can be
+%D used to pass info to the inclusion macro. Some examples
+%D of its use can be found in the modules \type{supp-tpi} and
+%D \type{prag-log}.
+
+%D For some reason, \METAPOST\ needs the public domain \DVI\ to
+%D \POSTSCRIPT\ converter \DVIPS. This symbiosis originates in
+%D the need to include the fonts (glyphs) that \METAPOST\ uses
+%D in the \POSTSCRIPT\ file. Driver independancy was one of my
+%D prerequisites for using \METAPOST, so I decided to build
+%D this kind of support myself. Personally I consider driver
+%D dependancy a drawback for the dissemination of such a
+%D package. The second part of this module more or less
+%D decouples \METAPOST\ and \DVIPS.
+%D
+%D The macros hereafter are copied from the module
+%D \type{m-metapost}. After writing module \type{supp-pdf} I
+%D added this method to the module named and after a while
+%D decided to hook it into module \type{spec-yy}. Therefore
+%D they made it into a support module, but in a slightly
+%D different way.
+
+%D \macros
+%D {UseMetaPostGraphic, DontUseMetaPostGraphics}
+%D {}
+%D
+%D The method we use is both robust and simple: one can do
+%D with calling the next macro with the filename as argument:
+%D
+%D \starttypen
+%D \UseMetaPostGraphic{filename}
+%D \stoptypen
+%D
+%D We can turn of this mechanism with:
+%D
+%D \starttypen
+%D \DontUseMetaPostGraphics
+%D \stoptypen
+
+\def\UseMetaPostGraphic#1%
+ {\bgroup
+ \message{[MP fonts #1]}%
+ %\uncatcodespecials
+ \endlinechar=-1
+ \setMPspecials
+ \obeyMPspecials
+ \setbox0=\hbox
+ {\hskip-\maxdimen
+ \doprocessfile\scratchread{#1}\handleMPSline}%
+ \smashbox0
+ \box0
+ \egroup}
+
+\def\DontUseMetaPostGraphics%
+ {\let\UseMetaPostGraphic=\gobbleoneargument}
+
+%D The characters are collected in a box and moved as far as
+%D possible into the left margin. The resulting box has no
+%D dimensions and can be prepended (appended) to the special
+%D that handles the inclusion. The characters are in the file
+%D but made invisible.
+
+%D We scan the graphics file for the \type{fshow} operator,
+%D that is, lines that start with \type{(}. If found it
+%D interprets the line, which looks like:
+%D
+%D \starttypen
+%D (string ... string) font size fshow
+%D \stoptypen
+%D
+%D Font definitions specified in the preamble are simply
+%D ignored. Only lines starting with \type{(} are interpreted.
+
+\def\dohandleMPSline#1#2\relax%
+ {\if#1(%
+ \expandafter\includeMPcharacters\fileline\relax
+ \fi}
+
+\def\handleMPSline%
+ {\expandafter\dohandleMPSline\fileline\relax}
+
+%D Before we start scanning for data, we first change some
+%D \CATCODES. The first set of macro's is copied from module
+%D \type{supp-pdf}. This scheme is a bit overdone for this
+%D module, but using the same macros saves us some memory.

+%D The lines starting with \type{(} are interpreted and
+%D handled by
+
+\def\includeMPcharacters(#1) #2 #3 #4\relax%
+ {\font\temp=#2 at #3bp\temp#1}
+
+%D This method is both robust and reasonable fast. The only
+%D disadvantage is that when not embedded properly in the
+%D graphics inclusion macros, one has to load all graphics by
+%D hand.
+
+%D Now let's see if things work all right and show the example
+%D files that are part of the \METAPOST\ distribution:
+%D
+%D \startregelcorrectie
+%D \steluitlijnenin[midden]
+%D \leavevmode
+%D \startcombinatie[3*3]

+%D There are 256 \COUNTERS, \DIMENSIONS, \SKIPS, \MUSKIPS\ and
+%D \BOXES, 16~in- and output buffers, but there is only one
+%D \MARK. In TugBoat~8 (1987, no~1) Jim Fox presents a set of
+%D macros that can be used to mimmick multiple marks. We
+%D gladly adopt them here.
+
+\writestatus{loading}{Context Support Macros / Marks}
+
+\unprotect
+
+%D This implementation is more or less compatible with the
+%D other register macros in \PLAIN\ \TEX. A mark is defined by:
+%D
+%D \starttypen
+%D \newmark\name
+%D \stoptypen
+%D
+%D and can be called upon with:
+%D
+%D \starttypen
+%D \topname
+%D \botname
+%D \firstname
+%D \stoptypen
+%D
+%D The only drawback of his approach is that the marks must be
+%D preloaded in the output routine. This is accomplished by
+%D means of:
+%D
+%D \starttypen
+%D \getmarks\name
+%D \stoptypen
+%D
+%D The macros presented here are in most aspects copies of
+%D those presented by Jim Fox. We've taken the freedom to
+%D change a few things for more or less obvious reasons:
+%D
+%D \startopsomming
+%D \som Because the original macros look quite complicated,
+%D which is mainly due to extensive use of
+%D \type{\expandafter}'s and \type{\csname}'s, we changed
+%D those in favor of \type{\getvalue}.
+%D \som To be more in line with the rest of \CONTEXT, we've
+%D changed some of the names of macros.
+%D \som Because we are already short on \COUNTERS\ we use
+%D macros when possible.
+%D \som We maintain a list of defined marks and use one
+%D call for getting them all at once.
+%D \som We have extended the mechanism to splitmarks (not
+%D perfected yet).
+%D \som We've introduced optional expansion of the contents
+%D of marks.
+%D \stopopsomming
+%D
+%D Whatever changes we've made, the credits still go to Jim,
+%D whatever goes wrong is due to me. The method is described
+%D in the TugBoat mentioned before, so we won't go into
+%D details. All marks belonging to a group are packed in a
+%D list. In this list they are preceded by a macro that can
+%D be defined at will and a number concerning the position at
+%D which it was defined.
+%D
+%D \starttypen
+%D \def\somelist{... \domark5{this} ... \domark31{that} ...}
+%D \stoptypen
+%D
+%D The original \type{\mark} keeps track of the number and
+%D \type{\topmark} and \type{\botmark} are used to extract the
+%D actual marks from the list. The counting is done by
+%D
+%D \starttypen
+%D \currentmarker
+%D \stoptypen
+%D
+%D In \CONTEXT\ we use the mark mechanism to keep track of
+%D colors. In a complicated documents with many colors per
+%D page, \type{\currentmarker} can therefore get pretty high.
+%D (Well, this is not completely true, because we don't
+%D always have to use marks.)
+
+\newcount\currentmarker
+
+%D The original implementation used a few more \COUNTERS. Two
+%D have been substituted by macros, one has been replaced by
+%D our scratch counter.
+%D
+%D \starttypen
+%D % \newcount\topmarker
+%D % \newcount\botmarker
+%D % \newcount\foundmarker
+%D \stoptypen
+%D
+%D We've also introduced some constants, one for the lists and
+%D three for composing the mark commands.
+
+\def\@@marklist@@ {marklist}
+\def\@@marktop@@ {top}
+\def\@@markbot@@ {bot}
+\def\@@markfirst@@ {first}
+
+%D The next one is new too. All defined marks are packed in a
+%D comma seperated list. This could of course have been a token
+%D list but \CONTEXT\ has some preference for comma lists.
+
+\def\markers {}
+
+%D \macros
+%D {expandmarks}
+%D {}
+%D
+%D There are two booleans. The first one handles the first
+%D marks, the second concerns expansion. This second one is
+%D new.
+
+\newif\ifnofirstmarker
+\newif\ifexpandmarks \expandmarkstrue
+
+%D We use an indirect call to the mack mechanism.
+
+\let\normalmark = \mark
+\let\normaltopmark = \topmark
+\let\normalbotmark = \botmark
+\let\normalfirstmark = \firstmark
+\let\normalsplitbotmark = \splitbotmark
+\let\normalsplitfirstmark = \splitfirstmark
+
+%D The next macro replaces the multiple step expansion and
+%D command name constructors of Jim. This alternative leads to
+%D a more readable source (we hope).

+%D \macros
+%D {newmark}
+%D {}
+%D
+%D A mark is defined by \type{\newmark}. At the same time,
+%D the name of the mark is added to a commalist. The
+%D three initializations were not in the original design, but
+%D make calls from outside the output routine a bit more
+%D robust.

+%D Setting a new mark and adding a mark to the designated

+%D command, the user set a marks bij calling it's name:
+%D
+%D \starttypen

+%D
+%D In fact, marks make only sense in the output routine. Marks
+%D are derived from their list by means of \type{\getmarks}.
+%D Only one call per mark is permitted in the output routine.
+%D Therefore, it's far more easy to get them all at once, by
+%D means of \type{\getallmarks}, which is not part of the
+%D original design.
+%D
+%D This grabbing is done by processing the list using the

+%D One final advice. Use marks with care. When used in globally
+%D assigned boxes, the list can grow quite big, and processing
+%D can slow down considerably.

+%D Multi||column output: the main routines
+%D
+%D The following macro's implement a multi||column output
+%D routine. The original implementation was based on Donald
+%D Knuth's implementation, which was adapted by Craig Platt to
+%D support balancing of the last page. I gradually adapted
+%D Platt's version to our needs but under certain
+%D circumstances things still went wrong. I considered all
+%D calls to Platt's \type{\balancingerror} as undesirable.

+%D This completely new implementation can handle enough
+%D situations for everyday documents, but is still far from
+%D perfect. While at the moment the routine doesn't support
+%D all kind of floats, it does support:
+%D
+%D \startopsomming
+%D \som an unlimitted number of columns
+%D \som ragged or not ragged bottoms
+%D \som optional balancing without \type{\balancingerrors}
+%D \som different \type{\baselineskips}, \type{\spacing},
+%D \type{\topskip} and \type{\maxdepth}
+%D \som left- and right indentation, e.g. within lists
+%D \som moving columns floats to the next column or page
+%D \som handling of floats that are to wide for a columns
+%D \stopopsomming
+%D
+%D One could wonder why single and multi||columns modes are
+%D still separated. One reason for this is that \TeX\ is not
+%D suited well for handling multi||columns. As a result, the
+%D single columns routines are more robust. Handling one
+%D column as a special case of multi||columns is posible but at
+%D the cost of worse float handling, worse page breaking,
+%D worse etc. Complicated multi||column page handling should
+%D be done in \kap{DTP}||systems anyway.
+%D
+%D There are three commands provided for entering and leaving
+%D multi||column mode and for going to the next column:
+%D
+%D \interface \type{\beginmulticolumns} \\ \\
+%D \interface \type{\endmulticolumns} \\ \\
+%D \interface \type{\ejectcolumn} \\ \\
+%D
+%D This routines are sort of stand||alone. They communicate
+%D with the rest of \CONTEXT\ by means of some interface
+%D macro's, which we only mention.
+%D
+%D \interface \type{\nofcolumns} \\
+%D the number of columns \\
+%D \interface \type{\betweencolumns} \\
+%D the stuff between columns \\
+%D \interface \type{\finaloutput{material}} \\
+%D some kind of \type{\pagebody} and \type{\shipout} \\
+%D

+%D \interface \type{\ifstretchcolumns} \\
+%D ragging the bottom or not \\

+%D do something special (a hook) \\
+%D \interface \type{\postprocesscolumnline} \\
+%D do something with each columnline (also a hook) \\
+%D \interface \type{\currentcolumn} \\
+%D the current column \\
+%D
+%D These interface macro's are called upon or initialized
+%D by the multi||column macro's.

+%D During initialization the temporary boxes are allocated.
+%D This enables us to use as much columns as we want, without
+%D exhausting the pool of boxes too fast. We could have packed
+%D them in one box, but we've got enough boxes.
+%D
+%D Two sets of boxes are declared, the txtboxes are used for
+%D the text, the topboxes are for moved column floats.

+
+%D Without going in details we present two macro's which
+%D handle the columns. The action which is transfered by the
+%D the first and only parameter can do something with
+%D \type{\currentcolumnbox}. In case of the mid columns,
+%D \type{\firstcolumnbox} and \type{\lastcolumnbox} are handled
+%D outside these macro's.

+
+%D Going to a new columns is done by means of a
+%D \type{\ejectcolumn}. The following definition does not
+%D always work.
+
+\def\ejectcolumn%
+ {\goodbreak
+ \showmessage{\m!columns}{2}{}}
+
+%D The next macro should never be called so let's deal with it.
+%D There were several solutions to these kind of errors. First
+%D we check for a good breakpoint before firing up the
+%D multi||column routine (\type{\break} or \type{\allowbreak}).
+%D We do the same at the end of the routine
+%D (\type{\allowbreak}). These allowances are definitely
+%D needed!
+%D
+%D Some on first sight redundant calls to for instance
+%D \type{\setvsize} in the flushing, splitting and balancing
+%D macro's can definitely not be omitted! Some are just there
+%D to handle situations that only few times arise. One of
+%D those can be that the output routine is invoked before
+%D everything is taken care of. This happens when we
+%D flush (part of) the current page with an \type{\unvbox}
+%D with a \type{\pagetotal}~$\approx$ \type{\pagegoal}. One
+%D simply cannot balance columns that are just balanced.
+%D
+%D I hope one never sees the following message. Because it
+%D took me a lot of time to develop the multi||columns
+%D routines, every (although seldom) warning gives me the
+%D creeps!
+
+\def\balancingerror%
+ {\showmessage{\m!columns}{3}{}%
+ \finaloutput{\unvbox255}}
+
+%D Here we present the two \type{\dont...} macro's, which are
+%D of course \CONTEXT||specific ones.

+ \fi}%
+ \doaddinsertionheight\topins
+ \doaddinsertionheight\botins
+ \doaddinsertionheight\footins}
+
+%D The local column width is available in the dimension
+%D register \type{\localcolumnwidth}, which is calculated as:
+
+\def\setcolumnhsize%
+ {\setbox0=\hbox{\parindent\!!zeropoint\betweencolumns}%
+ \intercolumnwidth=\wd0
+ \localcolumnwidth=\columntextwidth
+ \edef\globalcolumnwidth{\the\localcolumnwidth}%
+ \advance\localcolumnwidth by -\leftskip
+ \advance\localcolumnwidth by -\rightskip
+ \advance\localcolumnwidth by -\nofcolumns\intercolumnwidth
+ \advance\localcolumnwidth by \intercolumnwidth
+ \divide\localcolumnwidth by \nofcolumns
+ \usercolumnwidth=\localcolumnwidth
+ \hsize=\localcolumnwidth} % we don't do it \global
+
+%D One should be aware that when font related dimensions are
+%D used in typesetting the in||between material, these
+%D dimensions are influenced by corps switches inside
+%D multi||column mode.
+
+%D The global width is saved in \type {\globalcolumnwidth}.
+%D This value is used when we pack the columns in a \type
+%D {\hbox}.
+
+\def\setcolumnvsize%
+ {\global\vsize=\columntextheight
+ \ifdim\partialpageheight>\!!zeropoint
+ \global\advance\vsize by -\partialpageheight
+ \fi
+ \getinsertionheights\to\dimen0\\%
+ \global\advance\vsize by -\dimen0
+ \global\vsize=\nofcolumns\vsize
+ \global\pagegoal=\vsize} % let's do it only here
+
+%D It really starts here. After some checks and initializations
+%D we change the output routine to continous multi||column
+%D mode. This mode handles columns that fill the current and
+%D next full pages. The method used is (more or less)
+%D multiplying \type{\vsize} and dividing \type{\hsize} by
+%D \type{\nofcolumns}. More on this can be found in the
+%D \TeX book. We save the top of the current page in box
+%D \type{\partialpage}.
+%D
+%D We manipulate \type{\topskip} a bit, just to be shure that
+%D is has no flexibility. This has te be done every time a
+%D font switch takles place, because \type{\topskip} can depend
+%D on this.
+%D
+%D Watch the trick with the \type{\vbox}. This way we get the
+%D right interlining and white space.

+%D When we leave the multi||column mode, we have to process the
+%D not yet shipped out part of the columns. When we don't
+%D balance, we simply force a continuous output, but a balanced
+%D output is more tricky.
+%D
+%D First we try to fill up the page and when all or something
+%D is left we try to balance things. This is another useful
+%D adaption of the ancesters of these macro's. It takes some
+%D reasoning to find out what happens and maybe I'm making
+%D some mistake, but it works.
+%D
+%D Unvoiding box \type{\partialpage} is sometimes necessary,
+%D e.g. when there is no text given between \type{\begin..}
+%D and \type{\end..}. The \type{\par} is needed!

+
+%D Flushing the page comes to pasting the columns together and
+%D appending the result to box \type{\partialpage}, if not
+%D void. I've seen a lot of implementations in which some skip
+%D was put between normal text and multi||column text. When we
+%D don't want this, the baselines can be messed up. I hope the
+%D seemingly complicated calculation of a correction
+%D \type{\kern} is adequate to overcome this. Although not
+%D watertight, spacing is taken into account and even multiple
+%D mode changes on one page go well. But cross your fingers and
+%D don't blame me.
+%D
+%D One of the complications of flushing out the boxes is that
+%D \type{\partialpage} needs to be \type{\unvbox}'ed, otherwise
+%D there is too less flexibility in the page when using
+%D \type{\r@ggedbottom}. It took a lot of time before these
+%D kind of problems were overcome. Using \type{\unvbox} at the
+%D wrong moment can generate \type{\balancingerror}'s.
+%D
+%D One can use the macros \type {\maxcolumnheight} and \type
+%D {\maxcolumndepth} when generating material between columns
+%D as well as postprocessing column lines.

+
+%D In case one didn't notice, finaly \type{\finishcolumnbox} is
+%D applied to all boxes. One can use this hook for special
+%D purposes. But there is more:
+%D
+%D Once upon a time I wanted to manipulate the individual lines
+%D in a column. This feature is demonstrated in the two examples
+%D below.
+%D
+%D \startbuffer
+%D \def\postprocesscolumnline#1%
+%D {\ruledhbox{#1}\hss}
+%D
+%D \startkolommen[n=4]
+%D \dorecurse{25}{line: \recurselevel\par}
+%D \stopkolommen
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Here we show the natural width of the lines:
+%D
+%D {\haalbuffer}
+%D
+%D The next example does a bit more advanced manipulation:
+%D
+%D \startbuffer
+%D \def\postprocesscolumnline#1%
+%D {\ifodd\currentcolumn
+%D \hfill#1\relax
+%D \else
+%D \relax#1\hfill
+%D \fi}
+%D
+%D \startkolommen[n=4]
+%D \dorecurse{25}{line \recurselevel\par}
+%D \stopkolommen
+%D \stopbuffer
+%D
+%D \typebuffer
+%D
+%D Here we also see an application of \type{\currentcolumn}:
+%D
+%D {\haalbuffer}
+%D
+%D This feature is implemented using the reshape macros
+%D presented in \type{supp-box}.
+
+\def\postprocesscolumns% recent extension
+ {\ifx\postprocesscolumnline\undefined \else

+
+%D We default to doing nothing!
+
+\let\postprocesscolumnline=\undefined
+
+%D Here comes the simple splitting routine. It's a bit
+%D longer than expected because of ragging bottoms or not.
+%D This part can be a bit shorter but I suppose that I will
+%D forget what happens. The splitting takes some already
+%D present material (think of floats) into account!
+%D
+%D First we present some auxiliary routines. Any material,
+%D like for instance floats, that is already present in the
+%D boxes is preserved.

+%D The multicolumn mechanism is incorporated in a \CONTEXT\
+%D interface, which acts like:
+%D
+%D \starttypen
+%D \startcolumns[n=4,balance=no,stretch=no,line=on]
+%D some text
+%D \stopcolumns
+%D \stoptypen
+%D
+%D The setup is optional. The default behaviour of columns
+%D can be set up with:
+%D
+%D \starttypen
+%D \setupcolumns
+%D [n=2,
+%D balance=yes,
+%D stretch=text,
+%D line=off]
+%D \stoptypen
+%D
+%D In this case, stretching is according to the way it's
+%D done outside columns (\type{\inheritcolumnstrue}). Also
+%D we can setup the \type{tolerance} within a column, the
+%D \type{distance} between columns and the fixed
+%D \type{height} of a column.
+
+%D Multi||column output: the float routines
+%D
+%D Here come the routines that handle the placement of column
+%D floats. Floats that are to big migrate to the next
+%D column. Floats that are too wide, migrate to the top of the
+%D next page, where they span as much columns as needed.
+%D Floats that are left over from outside the multi||column
+%D mode are flushed first. In macro \type{\finaloutput} the
+%D topfloats that are left from previous text should be set.
+%D
+%D When there are some floats in the queue, we inhibit the
+%D flushing of floats on top of columns. The number of
+%D waiting floats is preswent in \type{\savednoftopfloats} and
+%D is saved. As long as there are floats waiting, the topfloats
+%D are places as if we are outside multi||column mode. This is
+%D neccessary for e.g. multicolumn lists.
+%D
+%D When all those floats are flushed, we switch to the local
+%D flushing routine.

+%D We need to calculate the amount of free space in a columns.
+%D When there is not enough room, we migrate the float to the
+%D next column. These macro's are alternatives (and
+%D look||alikes) of \type{\doroomfloat}. When a float is to
+%D wide, for one column, it is moved to the top of the next
+%D page. Of course such moved floats have to be taken into
+%D account when we calculate the available space. It's a pitty
+%D that such things are no integral part of \TEX.

+%D This were the multi||column routines. They can and need to

+%D
+%D One inprovement can be to normalize the height of floats

+%D \PDFTEX\ supports verbatim inclusion of \PDF\ code. The
+%D following macro takes care of inserting externally defined
+%D illustrations in \PDF\ format. According to a suggestion
+%D Tanmoy Bhattacharya posted to the \PDFTEX\ mailing list, we
+%D first skip lines until \type{stream} is reached and then
+%D copy lines until \type{endstream} is encountered. This
+%D scheme only works with vectorized graphics in which no
+%D indirect references to objects are used. Bitmaps also don't
+%D work. Interpreting their specifications is beyond the
+%D current implementation.
+%D
+%D \starttypen
+%D \convertPDFtoPDF
+%D {filename}
+%D {x scale} {y scale}
+%D {x offset } {y offset}
+%D {width} {height}
+%D \stoptypen
+%D
+%D When the scales are set to~1, the last last four values
+%D are the same as the bounding box, e.g.
+%D
+%D \starttypen
+%D \convertPDFtoPDF{mp-pra-1.pdf} {1} {1}{-1bp}{-1bp}{398bp}{398bp}
+%D \convertPDFtoPDF{mp-pra-1.pdf}{.5}{.5} {0bp} {0bp}{199bp}{199bp}
+%D \stoptypen
+%D
+%D Keep in mind, that this kind of copying only works for
+%D pure and valid pdf code (without fonts).

+%D The scanning and copying is straightforward and quite fast.

+%D In \POSTSCRIPT\ arguments precede the operators. Due to the
+%D fact that in some translations we need access to those
+%D arguments, as well as that sometimes we have to skip them,
+%D we stack them up. The stack is one||dimensional for non path
+%D operators and two||dimensional for operators inside a path.
+%D This is because we have to save the whole path for
+%D (optional) postprocessing. Values are pushed onto the stack
+%D by:
+%D
+%D \starttypen
+%D \setMPargument {value}
+%D \stoptypen
+%D
+%D They can be retrieved by the short named macros:
+%D
+%D \starttypen
+%D \gMPa {number}
+%D \sMPa {number}
+%D \stoptypen
+%D
+%D When scanning a path specification, we also save the
+%D operator, using
+%D
+%D \starttypen
+%D \setMPkeyword {n}
+%D \stoptypen
+%D
+%D The path drawing operators are coded for speed: \type{clip},
+%D \type{stroke}, \type{fill} and \type{fillstroke} become
+%D 1, 2, 3 and~4.
+%D
+%D When processing the path this code can be retrieved
+%D using
+%D
+%D \starttypen
+%D \getMPkeyword{n}
+%D \stoptypen
+%D
+%D When setting an argument, the exact position on the stack
+%D depend on the current value of the \COUNTERS\
+%D \type{\nofMPsegments} and \type{\nofMParguments}.
+
+\newcount\nofMPsegments
+\newcount\nofMParguments
+
+%D These variables hold the coordinates. The argument part of
+%D the stack is reset by:
+%D
+%D \starttypen
+%D \resetMPstack
+%D \stoptypen
+%D
+%D We use the prefix \type{@@MP} to keep the stack from
+%D conflicting with existing macros. To speed up things bit
+%D more, we use the constant \type{\@@MP}.
+
+\def\@@MP{@@MP}
+
+\def\setMPargument#1%
+ {\advance\nofMParguments by 1
+ \expandafter\def

+ \advance\nofMPsegments by 1
+ \nofMParguments=0\relax}
+
+\def\getMPkeyword#1%
+ {\csname\@@MP#10\endcsname}
+
+%D When we reset the stack, we can assume that all further
+%D comment is to be ignored as well as handled in strings.
+%D By redefining the reset macro after the first call, we
+%D save some run time.
+

+%D The arguments are saved with the preceding command
+%D \type{\do}. By default this command expands to nothing, but
+%D when we deal with strings it's used to strip off the
+%D \type{(} and \type{)}.
+%D
+%D Strings are kind of tricky, because characters can be
+%D passed verbatim \type{(hello)}, by octal number
+%D \type{(\005)} or as command \type{(\()}. We therefore
+%D cannot simply ignore \type{(} and \type{)}, the way we do
+%D with \type{[} and \type{]}. Another complication is that
+%D strings may contain characters that normally have a
+%D special meaning in \TEX, like \type{$} and \type{{}}.
+%D
+%D A previous solution made \type{\} an active character and
+%D let it look ahead for a number or character. W ehad to
+%D abandon this scheme because of the need for verbatim
+%D support. The next solution involved some \CATCODE\
+%D trickery but works well.

+%D \METAPOST\ draws it dots by moving to a location and
+%D invoking \type{0 0 rlineto}. This operator is not
+%D available in \PDF. Our solution is straightforward: we draw

+%D The \type{setlinewidth} commands look a bit complicated. There are
+%D two alternatives, that alsways look the same. As John Hobby
+%D says:
+%D
+%D \startsmaller
+%D \starttypen
+%D x 0 dtransform exch truncate exch idtransform pop setlinewidth
+%D 0 y dtransform truncate idtransform setlinewidth pop
+%D \stoptypen
+%D
+%D These are just fancy versions of \type{x setlinewidth} and
+%D \type{y setlinewidth}. The \type{x 0 ...} form is used if
+%D the path is {\em primarily vertical}. It rounds the width
+%D so that vertical lines come out an integer number of pixels
+%D wide in device space. The \type{0 y ...} form does the same
+%D for paths that are {\em primarily horizontal}. The reason
+%D why I did this is Knuth insists on getting exactly the
+%D widths \TEX\ intends for the horizontal and vertical rules
+%D in \type{btex...etex} output. (Note that PostScript scan
+%D conversion rules cause a horizontal or vertical line of
+%D integer width $n$ in device space to come out $n+1$ pixels
+%D wide, regardless of the phase relative to the pixel grid.)
+%D \stopsmaller
+%D
+%D The common operator in these sequences is \type{dtransform},
+%D so we can use this one to trigger setting the linewidth.

+%D The most complicated command is \type{concat}. \METAPOST\
+%D applies this operator to \type{stoke}. At that moment the
+%D points set by \type{curveto} and \type{moveto}, are already
+%D fixed. In \PDF\ however the \type{cm} operator affects the
+%D points as well as the pen (stroke). Like more \PDF\
+%D operators, \type{cm} is a defined in a bit ambiguous way.
+%D The only save route for non||circular penshapes, is saving
+%D teh path, recalculating the points and applying the
+%D transformation matrix in such a way that we can be sure
+%D that its behavior is well defined. This comes down to
+%D inverting the path and applying \type{cm} to that path as
+%D well as the pen. This all means that we have to save the
+%D path.
+
+%D In \METAPOST\ there are three ways to handle a path $p$:
+%D
+%D \starttypen
+%D draw p; fill p; filldraw p;
+%D \stoptypen
+%D
+%D The last case outputs a \type{gsave fill grestore} before
+%D \type{stroke}. Handling the path outside the main loops
+%D saves about 40\% run time.\voetnoot{We can save some more by
+%D following the \METAPOST\ output routine, but for the moment
+%D we keep things simple.} Switching between the main loop and
+%D the path loop is done by means of the recursely called
+%D macro \type{\handleMPsequence}.

+%D The transformation of the coordinates is handled by one of
+%D the macros Tanmoy posted to the \PDFTEX\ mailing list.
+%D I rewrote and optimized the original macro to suit the other
+%D macros in this module.
+%D
+%D \starttypen
+%D \doMPconcat {x position} \xresult {y position} \yresult
+%D \stoptypen
+%D
+%D
+%D By setting the auxiliary \DIMENSIONS\ \type{\dimen0} upto
+%D \type{\dimen10} only once per path, we save over 20\% run
+%D time. Some more speed was gained by removing some parameter
+%D passing. These macros can be optimized a bit more by using
+%D more constants. There is however not much need for further
+%D optimization because penshapes usually are round and
+%D therefore need no transformation. Nevertheless we move the
+%D factor to the outer level and use bit different \type{pt}
+%D removal macro. Although the values represent base points,
+%D we converted them to pure points, simply because those can
+%D be converted back.

+%D The following explanation of the conversion process was
+%D posted to the \PDFTEX\ mailing list by Tanmoy. The original
+%D macro was part of a set of macro's that included sinus and
+%D cosinus calculation as well as scaling and translating. The
+%D \METAPOST\ to \PDF\ conversion however only needs
+%D transformation.

+%D Given a point $(U_x, U_y)$ in user coordinates, the business
+%D of \POSTSCRIPT\ is to convert it to device space. Let us say
+%D that the device space coordinates are $(D_x, D_y)$. Then, in
+%D \POSTSCRIPT\ $(D_x, D_y)$ can be written in terms of
+%D $(U_x, U_y)$ in matrix notation, either as
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{D_x&D_y&1\cr} = \pmatrix{U_x&U_y&1\cr}
+%D \pmatrix{s_x&r_x&0\cr
+%D r_y&s_y&0\cr
+%D t_x&t_y&1\cr}
+%D \stopformule
+%D
+%D or
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{D_x\cr D_y\cr 1} = \pmatrix{s_x&r_y&t_x\cr
+%D r_x&s_y&t_y\cr
+%D 0 &0 &1 \cr}
+%D \pmatrix{U_x\cr
+%D U_y\cr
+%D 1 \cr}
+%D \stopformule
+%D
+%D both of which is a shorthand for the same set of equations:
+%D
+%D \plaatsformule
+%D \startformule
+%D D_x = s_x U_x + r_y U_y + t_x
+%D \stopformule
+%D
+%D \plaatsformule
+%D \startformule
+%D D_y = r_x U_x + s_y U_y + t_y
+%D \stopformule
+%D
+%D which define what is called an `affine transformation'.
+%D
+%D \POSTSCRIPT\ represents the `transformation matrix' as a
+%D six element matrix instead of a $3\times 3$ array because
+%D three of the elements are always~0, 0 and~1. Thus the above
+%D transformation is written in postscript as $[s_x\, r_x\,
+%D r_y\, s_y\, t_x\, t_y]$. However, when doing any
+%D calculations, it is useful to go back to the original
+%D matrix notation (whichever: I will use the second) and
+%D continue from there.
+%D
+%D As an example, if the current transformation matrix is
+%D $[s_x\, r_x\, r_y\, s_y\, t_x\, t_y]$ and you say \typ{[a b
+%D c d e f] concat}, this means:
+%D
+%D \startsmaller
+%D Take the user space coordinates and transform them to an
+%D intermediate set of coordinates using array $[a\, b\, c\, d\,
+%D e\, f]$ as the transformation matrix.
+%D
+%D Take the intermediate set of coordinates and change them to
+%D device coordinates using array $[s_x\, r_x\, r_y\, s_y\, t_x\, t_y]$
+%D as the transformation matrix.
+%D \stopsmaller
+%D
+%D Well, what is the net effect? In matrix notation, it is
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{I_x\cr I_y\cr 1\cr} = \pmatrix{a&c&e\cr
+%D b&d&f\cr
+%D 0&0&1\cr}
+%D \pmatrix{U_x\cr

+%D where $(I_x, I_y)$ is the intermediate coordinate.
+%D
+%D Now, the beauty of the matrix notation is that when there is
+%D a chain of such matrix equations, one can always compose
+%D them into one matrix equation using the standard matrix
+%D composition law. The composite matrix from two matrices can
+%D be derived very easily: the element in the $i$\hoog{th}
+%D horizontal row and $j$\hoog{th} vertical column is
+%D calculated by`multiplying' the $i$\hoog{th} row of the first
+%D matrix and the $j$\hoog{th} column of the second matrix (and
+%D summing over the elements). Thus, in the above:
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{D_x\cr D_y\cr 1} = \pmatrix{s_x^\prime&r_y^\prime&t_x^\prime\cr
+%D r_x^\prime&s_y^\prime&t_y^\prime\cr
+%D 0 &0 &0 \cr}
+%D \pmatrix{U_x\cr
+%D U_y\cr
+%D 1 \cr}
+%D \stopformule
+%D
+%D with
+%D
+%D \plaatsformule
+%D \startformule
+%D \eqalign
+%D {s_x^\prime & = s_x a + r_y b \cr
+%D r_x^\prime & = r_x a + s_y b \cr
+%D r_y^\prime & = s_x c + r_y d \cr
+%D s_y^\prime & = r_x c + s_y d \cr
+%D t_x^\prime & = s_x e + r_y f + t_x \cr
+%D t_y^\prime & = r_x e + s_y f + t_y \cr}
+%D \stopformule
+
+%D In fact, the same rule is true not only when one is going
+%D from user coordinates to device coordinates, but whenever
+%D one is composing two `transformations' together
+%D (transformations are `associative'). Note that the formula
+%D is not symmetric: you have to keep track of which
+%D transformation existed before (i.e.\ the equivalent of
+%D $[s_x\, r_x\, r_y\, s_y\, t_x\, t_y]$) and which was
+%D specified later (i.e.\ the equivalent of $[a\, b\, c\, d\,
+%D e\, f]$). Note also that the language can be rather
+%D confusing: the one specified later `acts earlier',
+%D converting the user space coordinates to intermediate
+%D coordinates, which are then acted upon by the pre||existing
+%D transformation. The important point is that order of
+%D transformation matrices cannot be flipped (transformations
+%D are not `commutative').
+%D
+%D Now what does it mean to move a transformation matrix
+%D before a drawing? What it means is that given a point
+%D $(P_x, P_y)$ we need a different set of coordinates
+%D $(P_x^\prime, P_y^\prime)$ such that if the transformation
+%D acts on $(P_x^\prime, P_y^\prime)$, they produce $(P_x,
+%D P_y)$. That is we need to solve the set of equations:
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{P_x\cr P_y\cr 1\cr} = \pmatrix{s_x&r_y&t_x\cr
+%D r_x&s_y&t_y\cr
+%D 0 &0 &1 \cr}
+%D \pmatrix{P_x^\prime\cr
+%D P_y^\prime\cr
+%D 1 \cr}
+%D \stopformule
+%D
+%D Again matrix notation comes in handy (i.e. someone has
+%D already solved the problem for us): we need the inverse
+%D transformation matrix. The inverse transformation matrix can
+%D be calculated very easily: it is
+%D
+%D \plaatsformule
+%D \startformule
+%D \pmatrix{P_x^\prime\cr P_y^\prime\cr 1\cr} =
+%D \pmatrix{s_x^\prime&r_y^\prime&t_x^\prime\cr
+%D r_x^\prime&s_y^\prime&t_y^\prime\cr
+%D 0 &0 &1 \cr}
+%D \pmatrix{P_x\cr
+%D P_y\cr
+%D 1 \cr}
+%D \stopformule
+%D
+%D where, the inverse transformation matrix is given by
+%D
+%D \plaatsformule
+%D \startformule
+%D \eqalign
+%D {D & = s_x s_y - r_x r_y \cr
+%D s_x^\prime & = s_y / D \cr
+%D s_y^\prime & = s_x / D \cr
+%D r_x^\prime & = - r_x / D \cr
+%D r_y^\prime & = - r_y / D \cr
+%D t_x^\prime & = ( - s_y t_x + r_y t_y ) / D \cr
+%D t_y^\prime & = ( r_x t_x - s_x t_y ) / D \cr}
+%D \stopformule
+%D
+%D And you can see that when expanded out, this does
+%D give the formulas:
+%D
+%D \plaatsformule
+%D \startformule
+%D P_x^\prime = { { s_y(p_x-t_x) + r_y(t_y-p_y) } \over
+%D { s_x*s_y-r_x*r_y } }
+%D \stopformule
+%D
+%D \plaatsformule
+%D \startformule
+%D P_y^\prime = { { s_x(p_y-t_y) + r_x(t_x-p_x) } \over
+%D { s_x*s_y-r_x*r_y } }
+%D \stopformule
+%D
+%D The code works by representing a real number by converting
+%D it to a dimension to be put into a \DIMENSION\ register: 2.3 would
+%D be represented as 2.3pt for example. In this scheme,
+%D multiplying two numbers involves multiplying the \DIMENSION\
+%D registers and dividing by 65536. Accuracy demands that the
+%D division be done as late as possible, but overflow
+%D considerations need early division.
+%D
+%D Division involves dividing the two \DIMENSION\ registers and
+%D multiplying the result by 65536. Again, accuracy would
+%D demand that the numerator be multiplied (and|/|or the
+%D denominator divided) early: but that can lead to overflow
+%D which needs to be avoided.
+%D
+%D If nothing is known about the numbers to start with (in
+%D concat), I have chosen to divide the 65536 as a 256 in each
+%D operand. However, in the series calculating the sine and
+%D cosine, I know that the terms are small (because I never
+%D have an angle greater than 45 degrees), so I chose to
+%D apportion the factor in a different way.

+%D This module implements some \type{\special} manipulation
+%D macros. I needed these when I implemented the code that
+%D handles the conversion of \TPIC\ specials to \PDF\ code.
+
+\writestatus{loading}{Context Support Macros / Specials}
+
+%D When interpreting specials we need to do some basic scanning.
+%D For the moment we distinguish between three cases. We need
+%D
+%D \starttypen
+%D \special{tag: arguments}
+%D \special{tag arguments}
+%D \special{tag}
+%D \stoptypen
+%D
+%D We cannot be sure that the first case isn't
+%D
+%D \starttypen
+%D \special{tag:arguments}
+%D \stoptypen
+%D
+%D So we have to take care of that one too.
+
+%D \macros
+%D {redefinespecial}
+%D
+%D Specials that are to be interpreted are defined with
+%D commands like:
+%D
+%D \startbuffer[tmp-1]
+%D \redefinespecial a: \using#1\endspecial%
+%D {let's execute special 'a:' using '#1'}
+%D
+%D \redefinespecial a \using#1\endspecial%
+%D {let's execute special 'a' using '#1'}
+%D
+%D \redefinespecial a \using#1\endspecial%
+%D {let's execute special 'a' using nothing}
+%D \stopbuffer
+%D
+%D \typebuffer[tmp-1]
+%D
+%D The first two always take an argument, the last one not.
+%D The definition of this redefinition macro is not that
+%D complex. The names are internally tagged with \type{\@rds@}
+%D which saves both time and space.
+
+\def\@rds@{@rds@}
+
+\def\redefinespecial #1 %
+ {\setvalue{\@rds@#1}}
+
+%D \macros
+%D {mimmickspecials}
+%D
+%D Mimmicking specials is activated by saying:
+%D
+%D \starttypen
+%D \mimmickspecials
+%D \stoptypen
+%D
+%D This commands redefines the \PLAIN\ \TEX\ primitive
+%D \type{\special}.
+
+\def\mimmickspecials%
+ {\let\special=\domimmickspecial}
+
+%D The special mimmicking macro first looks if it can find an
+%D colon terminated tag, next it searches for a tag that end
+%D with a space. If both cannot find, the tag itself is treated
+%D without argument.
+
+\def\domimmickspecial#1%
+ {\domimmickcolonspecial#1:\relax/:\relax/\end}
+
+\def\domimmickcolonspecial#1:#2#3:\relax/#4\end%
+ {\ifx#2\relax
+ \domimmickspacespecial#1 \relax/ \relax/\end
+ \else
+ \dodomimmickspecial#1:\using#2#3\endspecial
+ \fi}
+
+\def\domimmickspacespecial#1 #2#3 \relax/#4\end%
+ {\ifx#2\relax
+ \dodomimmickspecial#1\using\endspecial
+ \else
+ \dodomimmickspecial#1\using#2#3\endspecial
+ \fi}
+
+\def\dodomimmickspecial#1\using#2\endspecial%
+ {\expandafter\ifx\csname\@rds@#1\endcsname\relax % \doifdefinedelse
+ \defaultspecial{#2}%
+ \else
+ %\message{[mimmick special #1 with #2#3]}%
+ \getvalue{\@rds@#1}\using#2\endspecial
+ \fi}
+
+%D Now let's show that things work the way we want, using the
+%D previous definitions of tag~a.
+%D
+%D \startbuffer[tmp-2]
+%D \mimmickspecials
+%D \special{a: 1 2 3 4 5}
+%D \special{a: 1 2 3 4 5}
+%D \special{a}
+%D \stopbuffer
+%D
+%D \typebuffer[tmp-2]
+%D
+%D Which results in:
+%D
+%D \startregels
+%D \haalbuffer[tmp-1]
+%D \haalbuffer[tmp-2]
+%D \stopregels
+
+%D \macros
+%D {mimmickspecial}
+%D
+%D When needed, one can call a mimmicked special directly by
+%D saying for instance:
+%D
+%D \starttypen
+%D \mimmickspecial a: \using...\endspecial
+%D \stoptypen
+%D
+%D This can be handy when specials have much in common.
+
+\def\mimmickspecial #1 %
+ {\getvalue{\@rds@#1}}
+
+%D \macros
+%D {normalspecial,defaultspecial}
+%D
+%D Unknown specials are passed to the default special handler.
+%D One can for instance ignore all further specials by saying
+%D \type{\normalspecial}:
+%D
+%D \starttypen
+%D \def\defaultspecial#1{\normalspecial}
+%D \stoptypen
+%D
+%D But here we default to idle.
+
+\let\normalspecial =\special
+\let\defaultspecial=\special

+%D This modules implements the conversion of graphic \TPIC\
+%D specials using \METAPOST.
+%D
+%D We reimplement the \TPIC\ specials using the special
+%D mimmicking mechanism implemented in the support module
+%D \type{supp-spe} as well as the \METAPOST\ run||time support
+%D implemented in \type{supp-mps}.

+
+%D Beware: we haven't activated both mechanism yet. This is
+%D to be done in the calling module.
+
+\unprotect
+
+%D When we want to mimmick \TPIC\ specials in \PDFTEX, we need
+%D to map its graphic primitives into \PDF\ ones. The main
+%D problem in doing so is that \PDF\ does not support b-splines
+%D directly and also does not offer us something to draw arcs.
+%D Of course all this scan be implemented in \TEX, and the
+%D first implementation of this module did so, but the results
+%D were not that satisfying. Not having used these specials
+%D before, I had for instance to find out that the \TPIC\
+%D specials were not that unambiguesly defined.
+%D
+%D Then, while discussing something else, Sebastian Ratz told
+%D me that the Web2c implementation that \PDFTEX\ is base upon,
+%D offers some rather discutable, but nevertheless handy
+%D feature:
+%D
+%D \starttypen
+%D \write18{execute program with arguments}
+%D \stoptypen
+%D
+%D Knowing this, I immediatelly decided to throw away the old
+%D conversion macros and use the marvelous \METAPOST, \TEX\
+%D related, drawing program to do the conversion in as high a
+%D quality as possible.
+%D
+%D implementation we're going to present here, not only uses
+%D for drawing purposes, but also uses the more efficient
+%D \METAPOST\ features to store the path.
+%D
+%D \in{Table}[tab:TPIC specials] lists the \TPIC\ specials as
+%D mentioned in the \LATEX\ Graphics Companion and the
+%D relevant part of the \DVIPS\ source. This list shows us
+%D that we have to store the path before we can use it, simply
+%D because we don't know in advance what actions to apply on
+%D it.

+
+%D The first problem we have to take care of is the fact that
+%D there is no decent begin or end of the drawing process
+%D defined. We can however be quite sure that writers of
+%D packages using these specials will put them into a box,
+%D simply because else this is the most common used way to
+%D treat something \TEX\ as as a whole, like:
+%D
+%D \starttypen
+%D \hbox{\special{}\special{}...}
+%D \stoptypen
+%D
+%D We just start a picture as soon as the first special is
+%D encountered, so this becomes:
+%D
+%D \starttypen
+%D \hbox{\openpicture\newspecial{}\newspecial{}...
+%D \stoptypen
+
+%D The first step in opening the picture is to start a group.
+%D Now we can savely use the egroup that closes the box to also
+%D end the picture.
+
+\def\startTPICspecials%
+ {\bgroup
+ \let\startTPICspecials=\relax
+ \aftergroup\stopTPICspecials
+ \startwritingMPgraphic
+ \writeMPgraphic{pair p[];}}
+
+%D As soon as we begin a picture, we inhibit nesting by
+%D relaxing the start macro. The first \METAPOST\ action we
+%D take is declaring an array of pairs named $p$.
+
+%D Ending the picture is invoked by closing the current group.
+%D Because the \TPIC\ picture comes out mirrored, we have to
+%D reflect the current \METAPOST\ picture, stored in the system
+%D variable {\it currentpicture}, around the $x$-axis.
+
+\def\stopTPICspecials%
+ {\writeMPgraphic
+ {currentpicture:=currentpicture reflectedabout ((0,0),(4095,0));}%
+ \stopwritingMPgraphic
+ \flushMPgraphics
+ \loadcurrentMPgraphic{}%

+ \ht\MPgraphic=\!!zeropoint
+ \wd\MPgraphic=\!!zeropoint
+ \dp\MPgraphic=\!!zeropoint
+ \box\MPgraphic
+ \egroup}
+
+%D Here the macro \type{\stopwritingMPgraphic} has to take care
+%D of executing and including the \METAPOST\ code.
+
+%D We need to keep track of the number of elements that form
+%D the path. This is needed because we don't know in advance
+%D how the points are to be connected.
+
+\newcount\TPICcounter
+
+%D When a path is draw, we can connect the points using a
+%D smooth curve of drawing straight lines. A closed path can be
+%D drawn or filled.
+
+\newif\ifTPICdraw
+\newif\ifTPICfill
+\newif\ifTPICcurve
+
+%D The \TPIC\ specials permit specifying the line and fill
+%D color as well as the linetype, which can be solid, dashed or
+%D dotted. We'll save those specifications as a \METAPOST\
+%D string, using:
+
+\let\TPIClinetype =\empty
+\let\TPICgrayscale=\empty
+
+%D The magic reduction factor $.07227$ is needed to map the
+%D \TPIC\ $1/1000$ of an inch to \POSTSCRIPT\ points. We cannot
+%D delegate this task to \METAPOST\ because this program does
+%D not accept values greater than 4095.
+
+%D I won't discuss all the specifics used in implementing
+%D the specials. The \METAPOST\ part is rather trivial. Many
+%D specials have much in common, so the amout of code is not
+%D that large.

+%D I have to admit that by using the \METAPOST\ B�zier cubics
+%D routines these implementation does produce better curves
+%D then most \DVI\ drivers do using the \TPIC\ prescribed
+%D b-splines. Take for instance the sequence:
+%D
+%D \starttypen
+%D \special{pa 2000 1000}
+%D \special{pa 1000 2000}
+%D \special{pa 0000 1000}
+%D \special{pa 1000 0000}
+%D \special{pa 2000 1000}
+%D \special{sp}
+%D \stoptypen
+%D
+%D One would expect that this code produced a closed circle,
+%D but the curve that comes out using b-splines is far from
+%D round. We can however savely asume that the arc producing
+%D specials will be used for drawing circle fragments, while
+%D the path specials will be used for arbitraty curves. And for
+%D b-splines to produce nice curves, one will often use many
+%D points to get the desired results. Therefore, using the
+%D \METAPOST\ B�zier curves will certainly produce similar and
+%D even better graphics, except in those rare cases where one
+%D uses delinberately the not that accurate features of
+%D b-splines. Hereby the user is warned.

+%D Verbatim typesetting, especially of \TEX\ sources, is a
+%D non||trivial task. This is a direct results of the fact that
+%D characters can have \CATCODES\ other than~11 and such
+%D characters needs a special treatment. What for instance is
+%D \TEX\ supposed to do when it encounters a \type{$} or an
+%D \type{#}? This module deals with these matters.
+
+\writestatus{loading}{Context Support Macros / Verbatim}
+
+%D The verbatim environment has some features, like coloring
+%D \TEX\ text, seldom found in other environments. Especially
+%D when the output of \TEX\ is viewed on an electronic medium,
+%D coloring has a positive influence on the readability of
+%D \TEX\ sources, so we found it very acceptable to dedicate
+%D half of this module to typesetting \TEX\ specific character
+%D sequences in color. In this module we'll also present some
+%D macro's for typesetting inline, display and file verbatim.
+%D The macro's are capable of handling \TAB\ too.
+%D
+%D This module shows a few tricks that are often overseen by
+%D novice, like the use of the \TEX\ primitive \type{\meaning}.
+%D First I'll show in what way the users are confronted with
+%D verbatim typesetting. Because we want to be able to test for
+%D symmetry and because we hate the method of closing down the
+%D verbatim mode with some strange active character, we will
+%D use the following construction for display verbatim:
+%D
+%D \starttypen
+%D \starttyping
+%D The Dutch word 'typen' stands for 'typing', therefore in the Dutch version
+%D one will not find the word 'verbatim'.
+%D \stoptyping
+%D \stoptypen
+%D
+%D In \CONTEXT\ files can be typed with \type{\typefile} and
+%D inline verbatim can be accomplished with \type{\type}. This
+%D last command comes in many flavors:
+%D
+%D \starttypen
+%D We can say \type<<something>> or \type{something}. The first one is a bit
+%D longer but also supports slanted typing, which accomplished by typing
+%D \type<<a <<slanted>> word>>. We can also use commands to enhance the text
+%D \type<<with <</bf boldfaced>> text>>. Just to be complete, we decided
+%D to accept also \LaTeX\ alike verbatim, which means that \type+something+
+%D and \type|something| are valid commands too. Of course we want the grouped
+%D alternatives to process \type{hello {\bf big} world}} with braces.
+%D \stoptypen
+%D
+%D In the core modules, we will build this support on top of
+%D this module. There these commands can be tuned with
+%D accompanying setup commands. There we can enable commands,
+%D slanted typing, control spaces, \TAB||handling and (here we
+%D are:) coloring. We can also setup surrounding white space
+%D and indenting. Here we'll only show some examples.
+
+\unprotect
+
+%D \macros
+%D {verbatimfont}
+%D {}
+%D
+%D When we are typesetting verbatim we use a non||proportional
+%D (mono spaced) font. Normally this font is available by
+%D calling \type{\tt}. In \CONTEXT\ this command does a
+%D complete font||style switch. There we could have stuck with
+%D \type{\tttf}.
+

+%D \macros
+%D {obeyedspace, obeyedtab, obeyedline, obeyedpage}
+%D {}
+%D
+%D We have followed Knuth in naming macros that make \SPACE,
+%D \NEWLINE\ and \NEWPAGE\ active and assigning them
+%D \type{\obeysomething}, but first we set some default values.
+
+\def\obeyedspace {\hbox{ }}

+\def\obeyedline {\par}
+\def\obeyedpage {\vfill\eject}
+
+%D \macros
+%D {controlspace,setcontrolspaces}
+%D {}
+%D
+%D First we define \type{\obeyspaces}. When we want visible
+%D spaces (control spaces) we only have to adapt the definition
+%D of \type{\obeyedspace} to:
+
+\def\controlspace {\hbox{\char32}}
+
+\bgroup

+\egroup
+
+%D \macros
+%D {obeytabs, obeylines, obeypages,
+%D ignoretabs, ignorelines, ignorepages}
+%D {}
+%D
+%D Next we take care of \NEWLINE\ and \NEWPAGE\ and because we
+%D want to be able to typeset listings that contain \TAB, we
+%D have to handle those too. Because we have to redefine the
+%D \NEWPAGE\ character locally, we redefine the meaning of
+%D this (often already) active character.

+%D Although the inline verbatim commands presented here will be
+%D extended and embedded in the core modules of \CONTEXT,
+%D they can be used separately. Both grouped and character
+%D alternatives are provided but \type{<<} and nested
+%D braces are implemented in the core module. This commands
+%D takes one argument: the closing command.
+%D
+%D \starttypen
+%D \processinlineverbatim{\closingcommand}
+%D \stoptypen
+%D
+%D One can define his own verbatim commands, which can be very
+%D simple:
+%D
+%D \starttypen
+%D \def\Verbatim {\processinlineverbatim\relax}
+%D \stoptypen
+%D
+%D or a bit more more complex:
+%D
+%D \starttypen
+%D \def\GroupedVerbatim%
+%D {\bgroup
+%D \dosomeusefullthings
+%D \processinlineverbatim\egroup}
+%D \stoptypen
+%D
+%D Before entering inline verbatim mode, we take care of the
+%D unwanted \TAB, \NEWLINE\ and \NEWPAGE\ characters and
+%D turn them into \SPACE. We need the double \type{\bgroup}
+%D construction to keep the closing command local.

+%D
+%D The closing command is executed afterwards as an internal
+%D command and therefore should not be given explicitly when
+%D typesetting inline verbatim.
+%D
+%D We can define a display verbatim environment with the
+%D command \type{\processdisplayverbatim} in the following way:
+%D
+%D \starttypen
+%D \processdisplayverbatim{\closingcommand}
+%D \stoptypen
+%D
+%D \noindent For instance, we can define a simple command like:
+%D
+%D \starttypen
+%D \def\BeginVerbatim {\processdisplayverbatim{EndVerbatim}}
+%D \stoptypen
+%D
+%D \noindent But we can also do more advance things like:
+%D
+%D \starttypen
+%D \def\BeginVerbatim {\bigskip \processdisplayverbatim{\EndVerbatim}}
+%D \def\EndVerbatim {\bigskip}
+%D \stoptypen
+%D
+%D When we compare these examples, we see that the backslash in
+%D the closing command is optional. One is free in actually
+%D defining a closing command. If one is defined, the command
+%D is executed after ending verbatim mode.

+%D turn this feature off by saying:
+%D
+%D \starttypen
+%D \skipfirstverbatimlinefalse
+%D \stoptypen
+
+\newif\ifskipfirstverbatimline \skipfirstverbatimlinetrue
+
+%D We save the closing sequence in \type{\endofverbatimcommand}
+%D in such a way that it can be compared on a line by line
+%D basis. For the conversion we use \type{\meaning}, which
+%D converts the line to non||expandable tokens. We reset
+%D \type{\parskip}, because we don't want inter||paragraph
+%D skips to creep into the verbatim source. Furthermore we
+%D \type{\relax} the line||processing macro while getting the
+%D rest of the first line. The initialization command
+%D \type{\setupcopyverbatim} does just what we expect it to do:
+%D it assigns all characters \CATCODE~11. Next we switch to
+%D french spacing and call for obeyance.

+%D As its name says, \type{\uncatcodecharacters} resets the
+%D \CATCODE\ of characters. When we use an upper bound of
+%D 127 or 255, depending in \type{\ifeightbitcharacters}. By
+%D counting down, we only have to use one counter. The
+%D macro \type{\setcatcodes} can be uses to set alternative
+%D values. The macro \type{\resetspecialcharacters} resets
+%D characters with special meanings. This macro is not used
+%D in the verbatim macros, but is best defined in this module.

+%D
+%D We're not finished dealing \CATCODES\ yet. In \CONTEXT\ we
+%D use only one auxiliary file, which deals with tables of
+%D contents, registers, two pass tracking, references etc. This
+%D file, as well as files concerning graphics, is processed when
+%D needed, which can be in the mid of typesetting verbatim.
+%D However, when reading in data in verbatim mode, we should
+%D temporary restore the normal \CATCODES, and that's exactly
+%D what the next macros do. Saving the catcodes can be
+%D disabled by saying \type{\localcatcodestrue}.
+
+%D The previous macros call for \type{\savecatcode}, which is
+%D implemented as:
+
+\newif\iflocalcatcodes
+
+\def\savecatcode%
+ {\iflocalcatcodes \else
+ \expandafter\edef\csname @@cc@@\the\scratchcounter\endcsname%
+ {\the\catcode\scratchcounter}%

+
+%D It's counterpart is:
+
+\def\restorecatcode%
+ {\expandafter\catcode\expandafter\scratchcounter\expandafter=
+ \csname @@cc@@\the\scratchcounter\endcsname}
+
+%D When we want to restore \CATCODES\ we call for
+%D \type{\restorecatcodes}, which default to \type{\relax}
+
+\let\restorecatcodes=\relax
+
+%D or when we've saves things calls for:
+
+\def\dorestorecatcodes%
+ {\iflocalcatcodes \else
+ \doprocesscatcodes\restorecatcode
+ \fi}
+
+%D We also provide an alternative, that forces grouping
+%D when needed. An application of this macros can be found in
+%D buffering data.

+
+%D The main copying routine of display verbatim does an
+%D ordinary string||compare on the saved closing command and
+%D the current line. The space after \type{#1} in the
+%D definition of \type{\next} is essential! As a result of
+%D using \type{\obeylines}, we have to use \type{%}'s after
+%D each line but none after the first \type{#1}.

+%D The actual typesetting of a line is done by a separate
+%D macro, which enables us to implement \TAB\ handling. The
+%D \type{\do} and \type{\dodo} macros take care of the

+%D first line. The \type{\relax} is used as an signal.
+
+%D \macros

+%D {}
+%D
+%D A careful reader will see that \type{\linepar} is reset.

+%D
+%D Empty lines in verbatim can lead to white space on top of
+%D a new page. Because this is not what we want, we turn
+%D them into vertical skips. This default behavior can be
+%D overruled by:
+%D
+%D \starttypen
+%D \obeyemptylines
+%D \stoptypen
+%D
+%D Although it would cost us only a few lines of code, we
+%D decided not to take care of multiple empty lines. When a
+%D (display) verbatim text contains more successive empty
+%D lines, this probably suits some purpose. When applicable,
+%D one can set the verbatim baselineskip.

+
+%D \TEX\ does not offer \type{\everyline}, which is a direct
+%D result of its advanced multi||pass paragraph typesetting
+%D mechanism. Because in verbatim mode paragraphs and lines are
+%D more or less equal, we can easily implement our own simple
+%D \type{\everyline} support.
+
+%D \macros
+%D {EveryPar, EveryLine}
+%D {}
+%D
+%D In this module we've reserved \type{\everypar} for the
+%D things to be done with paragraphs and \type{\everyline} for
+%D line specific actions. In \CONTEXT\ however, we use
+%D \type{\everypar} for placing side- and columnfloats,
+%D inhibiting indentation and some other purposes. In verbatim
+%D mode, every line becomes a paragraph, which means that
+%D \type{\everypar} is executed frequently. To be sure, the
+%D user specific use of both \type{\everyline} and
+%D \type{\everypar} is implemented by means of
+%D \type{\EveryLine} and \type{\EveryPar}.
+%D
+%D We still have to take care of the \TAB. A \TAB\ takes eight
+%D spaces and a \SPACE\ normally has a width of 0.5~em. Because
+%D we can be halfway a tabulation, we must keep track of the
+%D position. This takes time, especially when we print complete
+%D files, therefore we \type{\relax} this mechanism by default.

+%D These macro's can be used to construct the commands we
+%D mentioned in the beginning of this documentation. We leave
+%D this to the fantasy of the reader and only show some \PLAIN\
+%D \TEX\ alternatives for display verbatim and listings. We
+%D define three commands for typesetting inline text, display
+%D text and files verbatim. The inline alternative also accepts
+%D user supplied delimiters.
+%D
+%D \starttypen
+%D \type{text}
+%D
+%D \starttyping
+%D ... verbatim text ...
+%D \stoptyping
+%D
+%D \typefile{filename}
+%D \stoptypen
+%D
+%D We can turn on the options by:
+%D
+%D \starttypen
+%D \controlspacetrue
+%D \verbatimtabstrue
+%D \prettyverbatimtrue
+%D \stoptypen
+%D
+%D Here is the implementation:
+
+\newif\ifcontrolspace
+\newif\ifverbatimtabs
+\newif\ifprettyverbatim
+
+\def\presettyping%
+ {\ifcontrolspace
+ \let\obeyspace=\setcontrolspace
+ \fi
+ \ifverbatimtabs
+ \let\obeytabs=\settabskips
+ \fi
+ \ifprettyverbatim
+ \let\obeycharacters=\setupprettytextype
+ \fi}
+
+\def\type%
+ {\bgroup
+ \presettyping
+ \processinlineverbatim{\egroup}}
+
+\def\starttyping%
+ {\bgroup
+ \presettyping
+ \processdisplayverbatim{\stoptyping}}
+
+\def\stoptyping%
+ {\egroup}
+
+\def\typefile#1%
+ {\bgroup
+ \presettyping
+ \processfileverbatim{#1}%
+ \egroup}
+
+%D One can use the different \type{\obeysomething} commands to
+%D influence the behavior of these macro's. We use for instance
+%D \type{\obeycharacters} for making \type{/} an active
+%D character when we want to include typesetting commands.
+%D
+%D We'll spend the remainder of this article on coloring the
+%D verbatim text. At \PRAGMA\ we use the integrated environment
+%D \TEXEDIT\ for editing and processing \TEX\
+%D documents.\voetnoot{\TEXEDIT\ has been operative since
+%D 1991.} This program also supports real time spell checking
+%D and \TEX\ based file management. Although definitely not
+%D exclusive, the programs cooperate nicely with \CONTEXT.
+%D Because \TEX\ can be considered a tool for experts, we've
+%D tried to put as less a burden on non||technical users as
+%D possible. This is accomplished in the following ways:
+%D
+%D \startopsomming
+%D
+%D \som We've added some trivial symmetry checking to
+%D \TEXEDIT. Sources are checked for the use of brackets,
+%D braces, begin||end and start||stop like constructions,
+%D with or without arguments.
+%D
+%D \som Although \TEX\ is very tolerant to unformatted input,
+%D we stimulate users to make the \ASCII\ source as clean
+%D as possible. Many sources I've seen in distribution
+%D sets look so awful, that I sometimes wonder how people
+%D get them working. In our opinion, a good||looking
+%D source leads to less errors.
+%D
+%D \som We use parameter driven setups and make the commands
+%D as tolerant as possible. We don't accept commands that
+%D don't look nice in \ASCII.
+%D
+%D \som Finally ---I could have added some more--- we use
+%D color.
+%D
+%D \stopopsomming
+%D
+%D When in spell||checking||mode, the words spelled correctly
+%D are shown in {\em green}, the unknown or wrongly spelled
+%D words are in {\em red} and upto four categories of words,
+%D for instance passive verbs and nouns, become {\em blue}
+%D (or cyan) or {\em yellow}. Short and nearly always correct
+%D words are in white (on a black screen). This makes
+%D checking||on||the||fly very easy and convenient, especially
+%D because we place the accents automatically.
+%D
+%D In \TEX||mode we show \TEX||specific tokens and sequences of
+%D tokens in appropriate colors and again we use four colors.
+%D We use those colors in a way that supports parameter driven
+%D setups, table typesetting and easy visual checking of
+%D symmetry. Furthermore the text becomes more readable.
+%D
+%D \bgroup
+%D \chardef\ampersand =`\&
+%D \chardef\comment =`\%

+%D
+%D Macro||definition and style files often look quite green,
+%D because they contain many calls to macros. Pure text files
+%D on the other hand are mostly white (on the screen) and color
+%D clearly shows their structure.
+%D
+%D When I prepared the interactive \PDF\ manuals of \CONTEXT,
+%D \TEXEDIT\ and \PPCHTEX\ (1995), I decided to include the
+%D original source text of the manuals as an appendix. At every
+%D chapter or (sub)section the reader can go to the
+%D corresponding line in the source, just to see how things
+%D were done in \TEX. Of course, the reader can jump from the
+%D to corresponding typeset text too.
+%D
+%D Confronted with those long (boring) sources, I decided that
+%D a colored output, in accordance with \TEXEDIT\ would be
+%D nice. It would not only visually add some quality to the
+%D manual, but also make the sources more readable.
+%D
+%D Apart from a lot of \CATCODE||magic, programming the color
+%D macros was surprisingly easy. Although the macro's are
+%D hooked into the standard \CONTEXT\ verbatim mechanism, they
+%D are set up in a way that embedding them in another verbatim
+%D environment is possible.
+%D
+%D We can turn on coloring by reassigning
+%D \type{\obeycharacters}:
+%D
+%D \starttypen
+%D \let\obeycharacters=\setupprettytextype
+%D \stoptypen
+%D
+%D During pretty typesetting we can be in two states: {\em
+%D command} and {\em parameter}. The first condition becomes
+%D true if we encounter a backslash, the second state is
+%D entered when we meet a~\type{#}.
+
+\newif\ifintexcommand
+\newif\ifintexparameter
+
+%D \macros
+%D {splittexparameters}
+%D {}
+%D
+%D The mechanism described here, is meant to be used with
+%D color. It is nevertheless possible to use different fonts
+%D instead of distinctive colors. When using color, it's better
+%D to end parameter mode after the \type{#}. When on the
+%D other hand we use a slanted typeface for the hashmark, then
+%D a slanted number looks better.
+
+\newif\ifsplittexparameters \splittexparameterstrue
+
+%D \macros
+%D {splittexcontrols}
+%D {}
+%D
+%D With \type{\splittexcontrols} we can influence the way
+%D control characters are processed in macro names. By default,
+%D the \type{^^} part is uncolored. When this boolean is set to
+%D false, they get the same color as the other characters.
+
+\newif\ifsplittexcontrols \splittexcontrolstrue
+
+%D The next boolean is used for internal purposes only and
+%D keeps track of the length of the name. Because two||character
+%D sequences starting with a backslash are always seen as a
+%D command.
+
+\newif\iffirstintexcommand
+
+%D We use a maximum of four colors because more colors will
+%D distract too much. In the following table we show the
+%D logical names of the colors, their color and $rgb$ values.
+%D
+%D \plaatstabel{geen}
+%D \starttabel[|l|l|c|c|c|c|]

+%D This following poor mans implementation of color is based on
+%D PostScript. One can of course use grayscales too. In the
+%D core modules these macros are redefined to using the color
+%D mechanism present in \CONTEXT.

+%D One can redefine these two commands after loading this
+%D module. When available, one can also use appropriate
+%D font||switch macro's. We default to color.
+

+%D Here come the commands that are responsible for entering and
+%D leaving the two states. As we can see, they've got much in
+%D common.

+%D We've got nine types of characters. The first type concerns
+%D the grouping characters that become red and type seven takes
+%D care of the backslash. Type eight is the most recently added
+%D one and handles the control characters starting with
+%D \type{^^}. In the definition part at the end of this module
+%D we can see how characters are organized by type.

+%D Macro names normally only may contain characters, but in

+%D \type{!} and~\type{?}. Of course they are only colored
+%D (green) when they are part of a name.

+%D Here comes the main specification routine. In this macro we
+%D also have to change the escape character to \type{!} and use
+%D \type{X}, \type{Y} and \type{Z} for grouping and ignoring,
+%D which makes the result a bit less readable. Plain \TEX\
+%D defines \type{\+} as an outer macro, so we have to redefine

+%D This text was published in the \MAPS\ of the dutch \TEX\
+%D users group \NTG. In that article, the verbatim part of the
+%D text was set with the following commands for the examples:
+%D
+%D \starttypen
+%D \def\starttypen% We simplify the \ConTeXt\ macro.
+%D {\bgroup
+%D \everypar{} % We disable some troublesome mechanisms.
+%D \advance\leftskip by 1em
+%D \processdisplayverbatim{\stoptypen}}
+%D
+%D \def\stoptypen%
+%D {\egroup}
+%D \stoptypen
+%D
+%D The implementation itself was typeset with:
+%D
+%D \starttypen
+%D \def\startdefinition%
+%D {\bgroup
+%D \everypar{} % Again we disable some troublesome mechanisms.
+%D \let\obeycharacters=\setupprettytextype
+%D \EveryPar{\showparagraphcounter}%
+%D \EveryLine{\showlinecounter}%
+%D \verbatimcorps
+%D \processdisplayverbatim{\stopdefinition}}
+%D
+%D \def\stopdefinition%
+%D {\egroup}
+%D \stoptypen
+%D
+%D And because we have both \type{\EveryPar} and
+%D \type{\EveryLine} available, we can implement a dual
+%D numbering mechanism:
+%D
+%D \starttypen
+%D \newcount\paragraphcounter
+%D \newcount\linecounter
+%D
+%D \def\showparagraphcounter%
+%D {\llap
+%D {\bgroup
+%D \counterfont
+%D \hbox to 4em
+%D {\global\advance\paragraphcounter by 1
+%D \hss \the\paragraphcounter \hskip2em}%
+%D \egroup
+%D \hskip1em}}
+%D
+%D \def\showlinecounter%
+%D {\llap
+%D {\bgroup
+%D \counterfont
+%D \hbox to 2em
+%D {\global\advance\linecounter by 1
+%D \hss \the\linecounter}%
+%D \egroup
+%D \hskip1em}}
+%D \stoptypen
+%D
+%D One may have noticed that the \type{\EveryPar} is only
+%D executed once, because we consider each piece of verbatim
+%D as one paragraph. When one wants to take the empty lines
+%D into account, the following assignments are appropriate:
+%D
+%D \starttypen
+%D \EveryLine
+%D {\iflinepar
+%D \showparagraphcounter
+%D \fi
+%D \showlinecounter}
+%D \stoptypen
+%D
+%D In this case, nothing has to be assigned to \type{\EveryPar},
+%D maybe except of just another extra numbering scheme. The
+%D macros used to typeset this documentation are a bit more
+%D complicated, because we have to take take 'long' margin
+%D lists into account. When such a list exceeds the previous
+%D pargraph we postpone placement of the paragraph number till
+%D there's room. This way so it does not clash with the margin
+%D words.
+
+%D Normally such commands have to be embedded in a decent setup
+%D structure, where options can be set at will.
+%D
+%D Now let's summarize the most important commands.
+%D
+%D \starttypen
+%D \processinlineverbatim{\closingcommand}
+%D \processdisplayverbatim{\closingcommand}
+%D \processfileverbatim{filename}
+%D \stoptypen
+%D
+%D We can satisfy our own specific needs with the following
+%D interfacing macro's:
+%D
+%D \starttypen
+%D \obeyspaces \obeytabs \obeylines \obeypages \obeycharacters
+%D \stoptypen
+%D
+%D Some needs are fulfilled already with:
+%D
+%D \starttypen
+%D \setcontrolspace \settabskips \setupprettytextype
+%D \stoptypen
+%D
+%D lines can be enhanced with ornaments using:
+%D
+%D \starttypen
+%D \everypar \everyline \iflinepar
+%D \stoptypen
+%D
+%D and color support is implemented by:
+%D
+%D \starttypen
+%D \texbeginofpretty[#1] ... \texendofpretty
+%D \stoptypen
+%D
+%D We can influence the verbatim environment with the following
+%D macro and booleans:
+%D
+%D \starttypen
+%D \obeyemptylines \splittexparameters... \splittexcontrols...
+%D \stoptypen
+%D
+%D The color support macro can be redefined by the user. The
+%D parameter \type{#1} can be one of the four 'fixed'
+%D identifiers {\em texprettyone}, {\em texprettytwo}, {\em
+%D texprettythree} and {\em texprettyfour}. We have implemented a
+%D more or less general PostScript color support mechanism,
+%D using \type{specials}. One can toggle between color and
+%D grayscale with:
+%D
+%D \starttypen
+%D \setgrayverbatim \setcolorverbatim
+%D \stoptypen
+
+%D \macros
+%D {permitshiftedendofverbatim}
+%D {}
+%D
+%D We did not mention one drawback of the mechanism described
+%D here. The closing command must start at the first position
+%D of the line. In \CONTEXT\ we will not have this drawback,
+%D because we can test if the end command is a substring of the
+%D current line. The testing is done by two of the support
+%D macros, which of course are not available in a stand alone
+%D application of this module.

+%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 This module is still in development. Depending on my
+%D personal need and those of whoever uses it, the macros will
+%D be improved in terms of visualization, efficiency and
+%D compatibility.
+
+\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 {normalhbox,
+%D normalvbox,normalvtop}
+%D {}
+%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.
+
+\let\normalhbox = \hbox
+\let\normalvbox = \vbox
+\let\normalvtop = \vtop
+\let\normalvcenter = \vcenter
+
+%D \macros
+%D {normalhskip,
+%D normalvskip}
+%D {}
+%D
+%D Next come the flexible skips, which come in two flavors
+%D too. Like boxes these are handled with \TEX\ primitives.
+
+\let\normalhskip = \hskip
+\let\normalvskip = \vskip
+
+%D \macros
+%D {normalpenalty,
+%D normalkern}
+%D {}
+%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.
+
+\let\normalpenalty = \penalty
+\let\normalkern = \kern
+
+%D \macros
+%D {normalhglue,
+%D normalvglue}
+%D {}
+%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
+%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.
+
+\let\normalmkern = \mkern
+\let\normalmskip = \mskip
+
+%D \macros
+%D {hfilneg,
+%D vfilneg}
+%D {}
+%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\hfillneg%
+ {\normalhskip\!!zeropoint \!!plus-1fill\relax}
+
+\def\vfillneg%
+ {\normalvskip\!!zeropoint \!!plus-1fill\relax}
+
+%D \macros
+%D {normalhss,normalhfil,normalhfill,
+%D normalvss,normalvfil,normalvfill}
+%D {}
+%D
+%D The positive stretch primitives are used independant and in
+%D combination with \type{\leaders}.
+
+\let\normalhss = \hss
+\let\normalhfil = \hfil
+\let\normalhfill = \hfill
+\let\normalvss = \vss
+\let\normalvfil = \vfil
+\let\normalvfill = \vfill
+
+%D \macros
+%D {normalhfilneg,normalhfillneg,
+%D normalvfilneg,normalvfillneg}
+%D {}
+%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\normalhfilneg = \hfilneg
+\let\normalhfillneg = \hfillneg
+\let\normalvfilneg = \vfilneg
+\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.
+
+\def\rlap#1{\normalhbox to \!!zeropoint{#1\normalhss}}
+\def\llap#1{\normalhbox to \!!zeropoint{\normalhss#1}}

+%D \macros
+%D {makeruledbox}
+%D {}
+%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 \starttypen
+%D \makeruledbox0
+%D \stoptypen
+
+%D \macros
+%D {baselinerule,baselinefill}
+%D {}
+%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 \starttypen
+%D \baselineruletrue
+%D \baselinefilltrue
+%D \stoptypen
+%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
+%D Rules can be turned on and off, but by default we have:
+%D
+%D \starttypen
+%D \topruletrue
+%D \bottomruletrue
+%D \leftruletrue
+%D \rightruletrue
+%D \stoptypen
+%D
+%D As we see below:
+
+\newif\iftoprule \topruletrue
+\newif\ifbottomrule \bottomruletrue
+\newif\ifleftrule \leftruletrue
+\newif\ifrightrule \rightruletrue
+
+%D \macros
+%D {boxrulewidth}
+%D {}
+%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 \starttypen
+%D \boxrulewidth=.2pt
+%D \stoptypen
+%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 \startregelcorrectie
+%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 \stopregelcorrectie
+%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
+%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
+%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 \starttypen
+%D \ruledbox\hbox{What rules do you mean?}
+%D \stoptypen
+%D
+%D The macro \type{\setruledbox} can be used to directly
+%D rule a box.
+%D
+%D \starttypen
+%D \setruledbox12=\hbox{Who's talking about rules here?}
+%D \stoptypen
+%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:
+
+\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
+%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 \starttypen
+%D \ifflexible
+%D \ifzero
+%D \ifnegative
+%D \ifpositive
+%D \stoptypen
+%D
+%D These status variables are set when we call for one of the
+%D investigation macros, e.g.
+%D
+%D \starttypen
+%D \investigateskip\scratchskip
+%D \stoptypen
+%D
+%D We use some dirty trick to check stretchability of \SKIPS.
+%D Users of these macros are invited to study their exact
+%D behavior first. The positive and negative states both
+%D include zero and are in fact non-negative ($\geq0$) and
+%D non-positive ($\leq0$) .

+%D {dontinterfere}
+%D {}
+%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 \macros
+%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

+
+\def\dontcomplain%
+ {\hbadness = \!!tenthousand
+ \hfuzz = \maxdimen
+ \vbadness = \!!tenthousand
+ \vfuzz = \maxdimen}
+
+%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
+%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 \starttypen
+%D \centeredvcuetrue
+%D \stoptypen
+%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 \starttypen
+%D \def\normalvcue%
+%D {\normalhbox \ifcenteredvcue to \hsize \fi
+%D \bgroup\bgroup\normalhss
+%D \aftergroup\normalhss\aftergroup\egroup
+%D \let\next=}
+%D \stoptypen
+%D
+%D or the probably best one:
+%D
+%D \starttypen
+%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 \stoptypen
+%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
+%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 \starttypen
+%D \testrulewidth=\boxrulewidth
+%D \stoptypen
+%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
+%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 \startopsomming[opelkaar]
+%D \som line and pagebreaks are allowed at a skip
+%D \som skips can have a positive and/or negative
+%D stretchcomponent
+%D \stopopsomming
+%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 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
+%D The two macros \type{\redoglobal} and \type{\dodoglobal} are
+%D used in this and some other modules to enforce a user
+%D specified \type{\doglobal} action. The last and often only
+%D global assignment in a macro is done with
+%D \type{\dodoglobal}, but all preceding ones with
+%D \type{\redoglobal}. When using only alternatives, one can
+%D reset this mechanism with \type{\resetglobal}.

+%D \macros
+%D {newcounter,
+%D increment,decrement}
+%D {}
+%D
+%D Unfortunately the number of \COUNTERS\ in \TEX\ is limited,
+%D but fortunately we can store numbers in a macro. We can
+%D increment such pseudo \COUNTERS\ with \type{\increment}.
+%D
+%D \starttypen
+%D \increment(\counter,20)
+%D \increment(\counter,-4)
+%D \increment(\counter)
+%D \increment\counter
+%D \stoptypen
+%D
+%D After this sequence of commands, the value of
+%D \type{\counter} is 20, 16, 17 and~18. Of course there is
+%D also the complementary command \type{\decrement}.
+%D
+%D Global assignments are possible too, using \type{\doglobal}:
+%D
+%D \starttypen
+%D \doglobal\increment\counter
+%D \stoptypen
+%D
+%D When \type{\counter} is undefined, it's value is initialized
+%D at~0. It is nevertheless better to define a \COUNTER\
+%D explicitly. One reason could be that the \COUNTER\ can be
+%D part of a test with \type{\ifnum} and this conditional does
+%D not accept undefined macro's. The \COUNTER\ in our example
+%D can for instance be defined with:
+%D
+%D \starttypen
+%D \newcounter\counter
+%D \stoptypen
+%D
+%D The command \type{\newcounter} must not be confused with
+%D \type{\newcount}! Of course this mechanism is much slower
+%D than using \TEX's \COUNTERS\ directly. In practice
+%D \COUNTERS\ (and therefore our pseudo counters too) are
+%D seldom the bottleneck in the processing of a text. Apart
+%D from some other incompatilities we want to mention a pitfal
+%D when using \type{\ifnum}.
+%D
+%D \starttypen
+%D \ifnum\normalcounter=\pseudocounter \doif \else \doelse \fi
+%D \ifnum\pseudocounter=\normalcounter \doif \else \doelse \fi
+%D \stoptypen
+%D
+%D In the first test, \TEX\ continues it's search for the
+%D second number after reading \type{\pseudocounter}, while
+%D in the second test, it stops reading after having
+%D encountered a real one. Tests like the first one therefore
+%D can give unexpected results, for instance execution
+%D of \type{\doif} even if both numbers are unequal.

+%D \macros
+%D {newsignal}
+%D
+%D When writing advanced macros, we cannot do without
+%D signaling. A signal is a small (invisible) kern or penalty
+%D that signals the next macro that something just happened.
+%D This macro can take any action depending onthe previous
+%D signal. Signals must be unique and the next macro takes care
+%D of that.
+%D
+%D \starttypen
+%D \newsignal\somesignal

+%D \macros
+%D {newskimen}
+%D
+%D \TEX\ offers 256 \DIMENSIONS\ and \SKIPS. Unfortunately this
+%D amount is too small to suit certain packages. Therfore when
+%D possible one should use
+%D
+%D \starttypen
+%D \newskimen\tempskimen
+%D \stoptypen
+%D
+%D This commands allocates a \DIMENSION\ or a \SKIP, depending
+%D on the availability. One should be aware of the difference
+%D between both. When searching for some glue \TEX\ goes on
+%D searching till it's sure that no other glue component if
+%D found. This search can be canceled by using \type{\relax}
+%D when possible and needed.

+%D The next macro can be very useful when using \type{\csname}
+%D like in:
+%D
+%D \starttypen
+%D \csname if\strippedcsname\something\endcsname
+%D \stoptypen
+%D
+%D This expands to \type{\ifsomething}.

+\def\strippedcsname%

+
+%D \macros
+%D {newconditional,
+%D settrue, setfalse,
+%D ifconditional}
+%D {}
+%D
+%D \TEX's lacks boolean variables, although the \PLAIN\ format
+%D implements \type{\newif}. The main disadvantage of this
+%D scheme is that it takes three hash table entries. A more
+%D memory saving alternative is presented here. A conditional
+%D is defined by:
+%D
+%D \starttypen
+%D \newconditional\doublesided
+%D \setfalse
+%D
+%D Setting a conditional is done by \type{\settrue} and
+%D \type{\setfalse}:
+%D
+%D \starttypen
+%D \settrue\doublesided
+%D \setfalse
+%D
+%D while testing is accomplished by:
+%D
+%D \starttypen
+%D \ifconditional\doublesided ... \else ... \fi
+%D \setfalse
+%D
+%D We cannot use the simple scheme:
+%D
+%D \starttypen
+%D \def\settrue#1{\let#1=\iftrue}
+%D \def\settrue#1{\let#1=\iffalse}
+%D \stoptypen
+%D
+%D Such an implementation gives problems with nested
+%D conditionals. The next implementation is abaou as fast
+%D and just as straightforward:
+
+\def\settrue#1%
+ {\chardef#1=0 }
+
+\def\setfalse#1%
+ {\chardef#1=1 }
+
+\let\newconditional = \setfalse
+\let\ifconditional = \ifcase
+
+%D \macros
+%D {dorecurse,recurselevel,recursedepth
+%D dostepwiserecurse,
+%D for}
+%D {}
+%D
+%D \TEX\ does not offer us powerfull for||loop mechanisms. On
+%D the other hand its recursion engine is quite unique. We
+%D therefore identify the for||looping macros by this method.
+%D The most simple alternative is the one that only needs a
+%D number.
+%D
+%D \starttypen
+%D \dorecurse {n} {whatever we want}
+%D \stoptypen
+%D
+%D This macro can be nested without problems and therefore be
+%D used in situations where \PLAIN\ \TEX's \type{\loop} macro
+%D ungracefully fails. The current value of the counter is
+%D available in \type{\recurselevel}, before as well as after
+%D the \typ{whatever we wat} stuff.
+%D
+%D \starttypen
+%D \dorecurse % inner loop
+%D {10}
+%D {\recurselevel: % outer value
+%D \dorecurse % inner loop
+%D {\recurselevel} % outer value
+%D {\recurselevel} % inner value
+%D \dorecurse % inner loop
+%D {\recurselevel} % outer value
+%D {\recurselevel} % inner value
+%D \endgraf}
+%D \stoptypen
+%D
+%D In this example the first, second and fourth
+%D \type{\recurselevel} concern the outer loop, while the third
+%D and fifth one concern the inner loop. The depth of the
+%D nesting is available for inspection in \type{\recursedepth}.
+%D
+%D Both \type{\recurselevel} and \type{\recursedepth} are
+%D macros. The real \COUNTERS\ are hidden from the user because
+%D we don't want any interference.

+
+%D As we can see here, the simple command \type{\dorecurse} is
+%D a special case of the more general:
+%D
+%D \starttypen
+%D \dostepwiserecurse {from} {to} {step} {action}
+%D \stoptypen
+%D
+%D This commands accepts positive and negative steps. Illegal
+%D values are handles as good as possible and the macro accepts
+%D numbers and \COUNTERS.
+%D
+%D \starttypen
+%D \dostepwiserecurse {1} {10} {2} {...}
+%D \dostepwiserecurse {10} {1} {-2} {...}
+%D \stoptypen
+%D
+%D The third alternative looks a bit different and uses a
+%D pseudo counter. When this macro is nested, we have to use
+%D different counters. This time we use keywords.
+%D
+%D \starttypen
+%D \def\alfa{2} \def\beta{100} \def\gamma{3}
+%D
+%D \for \n=55 \to 100 \step 1 \do {... \n ...}
+%D \for \n=\alfa \to \beta \step \gamma \do {... \n ...}
+%D \for \n=\n \to 120 \step 1 \do {... \n ...}
+%D \for \n=120 \to 100 \step -3 \do {... \n ...}
+%D \for \n=55 \to 100 \step 2 \do {... \n ...}
+%D \stoptypen
+%D
+%D Only in the third example we need to predefine \type{\n}.
+%D The use of \type{\od} as a dilimiter would have made nested
+%D use more problematic.

+%D \macros
+%D {doloop,exitloop}
+%D {}
+%D
+%D Sometimes loops are not determined by counters, but by
+%D (a combinations of) conditions. We therefore implement a
+%D straightforward loop, which can only be left when we
+%D explictly exit it. Nesting is supported. First we present
+%D a more extensive alternative.
+%D
+%D \starttypen
+%D \doloop
+%D {Some kind of typesetting punishment \par
+%D \ifnum\pageno>100 \exitloop \fi}
+%D \stoptypen
+%D
+%D When needed, one can call for \type{\looplevel} and
+%D \type{\loopdepth}.

+
+\def\doloop%
+ {\dostepwiserecurse{1}{\maxdimen}{1}}
+
+\def\exitloop
+ {\setvalue{\@@irecurse\recursedepth}{\maxdimen}}
+
+%D We don't declare new counters for \type{\looplevel} and
+%D \type{\loopdepth} because one can use \type{\recurselevel}
+%D and \type{\recursedepth}.
+%D
+%D The loop is executed at least once, so beware of situations
+%D like:
+%D
+%D \starttypen
+%D \doloop {\exitloop some commands}
+%D \stoptypen
+%D
+%D It's just a matter of putting the text into the \type{\if}
+%D statement that should be there anyway, like in:
+%D
+%D \starttypen
+%D \doloop {\ifwhatever \exitloop \else some commands\fi}
+%D \stoptypen
+
+%D \macros
+%D {newevery,everyline,EveryLine,EveryPar}
+%D {}
+%D
+%D Lets skip to something quite different. It's common use
+%D to use \type{\everypar} for special purposes. In \CONTEXT\
+%D we use this primitive for locating sidefloats. This means
+%D that when user assignments to \type{\everypar} can interfere
+%D with those of the package. We therefore introduce
+%D \type{\EveryPar}.
+%D
+%D The same goes for \type{\EveryLine}. Because \TEX\ offers
+%D no \type{\everyline} primitive, we have to call for
+%D \type{\everyline} when we are working on a line by line
+%D basis. Just by calling \type{\EveryPar{}} and
+%D \type{\EveryLine{}} we restore the old situation.
+%D
+%D The definition command \type{\DoWithEvery} will be quite
+%D unreadable, so let's first show an implementation that
+%D shows how things are done:
+%D
+%D \starttypen
+%D \newtoks \everyline
+%D \newtoks \oldeveryline
+%D \newif \ifeveryline
+%D
+%D \def\DoWithEvery#1#2#3#4%

+%D \def\doEveryLine%
+%D {\DoWithEvery\everyline\oldeveryline\ifeveryline\everylinetrue}
+%D
+%D \def\EveryLine%
+%D {\afterassignment\doEveryLine\scratchtoks}
+%D
+%D The real implementation is a bit more complicated but we
+%D prefer something more versatile.
+
+\def\DoWithEvery#1%
+ {\csname if\strippedcsname#1\endcsname \else
+ \edef\next%
+ {\@EA\noexpand\csname old\strippedcsname#1\endcsname=
+ {\the#1}}%

+ \@EA\newif \csname if\strippedcsname#1\endcsname
+ \@EA\def \csname do\strippedcsname#2\endcsname{\DoWithEvery#1}%
+ \def#2{\dowithevery#2}%
+ \fi}
+
+%D This one permits definitions like:
+
+\newevery \everypar \EveryPar
+\newevery \everyline \EveryLine
+
+%D and how about:
+
+\newevery \neverypar \NeveryPar
+
+%D Which indeed we're going to use indeed!
+
+%D Technically spoken we could have used the method we are
+%D going to present in the visual debugger. First we save
+%D the primitive \type{\everypar}:
+%D
+%D \starttypen
+%D \let\normaleverypar=\everypar
+%D \stoptypen
+%D
+%D Next we allocate a \TOKENLIST\ named \type{\everypar},
+%D which means that \type{\everypar} is no longer a primitive
+%D but something like \type{\toks44}.
+%D
+%D \starttypen
+%D \newtoks\everypar
+%D \stoptypen
+%D
+%D Because \TEX\ now executes \type{\normaleverypar} instead
+%D of \type{\everypar}, we are ready to assign some tokens to
+%D this internally known and used \TOKENLIST.
+%D
+%D \starttypen
+%D \normaleverypar={all the things the system wants to do \the\everypar}
+%D \stoptypen
+%D
+%D Where the user can provide his own tokens to be expanded
+%D every time he expects them to expand.
+%D
+%D \starttypen
+%D \everypar={something the user wants to do}
+%D \stoptypen
+%D
+%D We don't use this method because it undoubtly leads to
+%D confusing situations, especially when other packages are
+%D used, but it's this kind of tricks that make \TEX\ so
+%D powerful.
+
+%D \macros
+%D {convertargument,convertcommand}
+%D {}
+%D
+%D Some persistent experimenting led us to the next macro. This
+%D macro converts a parameter or an expanded macro to it's
+%D textual meaning.
+%D
+%D \starttypen
+%D \convertargument ... \to \command
+%D \stoptypen
+%D
+%D For example,
+%D
+%D \starttypen
+%D \convertargument{one \two \three{four}}\to\ascii
+%D \stoptypen
+%D
+%D The resulting macro \type{\ascii} can be written to a file
+%D or the terminal without problems. In \CONTEXT\ we use this
+%D macro for generating registers and tables of contents.
+%D
+%D The second conversion alternative accepts a command:
+%D
+%D \starttypen
+%D \convertcommand\command\to\ascii
+%D \stoptypen
+%D
+%D Both commands accept the prefix \type{\doglobal} for global
+%D assignments.
+
+\def\doconvertargument#1>{}
+
+\def\convertedcommand%
+ {\expandafter\doconvertargument\meaning}
+
+\long\def\convertargument#1\to#2%
+ {\long\def\convertedargument{#1}%
+ \dodoglobal\edef#2%
+ {\convertedcommand\convertedargument}}
+
+\long\def\convertcommand#1\to#2%
+ {\dodoglobal\edef#2%
+ {\convertedcommand#1}}
+
+%D This is typically a macro that one comes to after reading
+%D the \TEX book carefully. Even then, the definite solution
+%D was found after rereading the \TEX book. The first
+%D implementation was:
+%D
+%D \starttypen
+%D \def\doconvertargument#1->#2\\\\{#2}
+%D \stoptypen
+%D
+%D The \type{-}, the delimiter \type{\\\\} and the the second
+%D argument are completely redundant.
+
+%D \macros
+%D {ExpandFirstAfter,ExpandSecondAfter,ExpandBothAfter}
+%D {}
+%D
+%D These three commands support expansion of arguments before
+%D executing the commands that uses them. We can best
+%D illustrate this with an example.
+%D
+%D \starttypen
+%D \def\first {alfa,beta,gamma}
+%D \def\second {alfa,epsilon,zeta}
+%D
+%D \ExpandFirstAfter \doifcommon {\first} {alfa} {\message{OK}}
+%D \ExpandSecondAfter \doifcommon {alfa} {\second} {\message{OK}}
+%D \ExpandBothAfter \doifcommon {\first} {\second} {\message{OK}}
+%D
+%D \ExpandFirstAfter\processcommalist[\first]\message
+%D
+%D \ExpandAfter \doifcommon {\first} {alfa} {\message{OK}}
+%D \stoptypen
+%D
+%D The first three calls result in the threefold message
+%D \type{OK}, the fourth one shows the three elements of
+%D \type{\first}. The command \type{\ExpandFirstAfter} takes
+%D care of (first) arguments that are delimited by \type{[ ]},
+%D but the faster \type{\ExpandAfter} does not.

+ {\ExpandBothAfter\v!ifinstringelse}

+%D \macros
+%D {ConvertToConstant,ConvertConstantAfter}
+%D {}
+%D
+%D When comparing arguments with a constant, we can get into
+%D trouble when this argument consists of tricky expandable
+%D commands. One solution for this is converting the
+%D argument to a string of unexpandable characters. To make
+%D comparison possible, we have to convert the constant too
+%D
+%D \starttypen
+%D \ConvertToConstant\doifelse {...} {...} {then ...} {else ...}
+%D \stoptypen
+%D
+%D This construction is only needed when the first argument
+%D can give troubles. Misuse can slow down processing.
+%D
+%D \starttypen
+%D \ConvertToConstant\doifelse{\c!alfa} {\c!alfa}{...}{...}
+%D \ConvertToConstant\doifelse{alfa} {\c!alfa}{...}{...}
+%D \ConvertToConstant\doifelse{alfa} {alfa} {...}{...}
+%D \ConvertToConstant\doifelse{alfa \alfa test}{\c!alfa}{...}{...}
+%D \stoptypen
+%D
+%D In examples~2 and~3 both arguments equal, in~1 and~4
+%D they differ.

+ {\expandafter\convertargument\expandafter{#2}\to\!!stringa
+ \expandafter\convertargument\expandafter{#3}\to\!!stringb
+ #1{\!!stringa}{\!!stringb}}
+
+%D When the argument \type{#1} consists of commands, we had
+%D better use
+%D
+%D \starttypen
+%D \ConvertConstantAfter\processaction[#1][...]
+%D \ConvertConstantAfter\doifelse{#1}{\v!iets}{}{}
+%D \stoptypen
+%D
+%D This commands accepts things like:
+%D
+%D \starttypen
+%D \v!constant
+%D constant
+%D \hbox to \hsize{\rubish}
+%D \stoptypen
+%D
+%D As we will see in the core moudles, this macro permits
+%D constructions like:
+%D
+%D \starttypen
+%D \setupfoottexts[...][...]
+%D \setupfoottexts[margin][...][...]
+%D \setupfoottexts[\v!margin][...][...]
+%D \stoptypen

+%D \macros
+%D {gobbleuntil,grabuntil,processbetween}
+%D {}
+%D
+%D In \TEX\ gobbling usually stand for skipping arguments, so
+%D here are our gobbling macros.
+%D
+%D In \CONTEXT\ we use a lot of \type{\start}||\type{\stop}
+%D like constructions. Sometimes, the \type{\stop} is used as a
+%D hard coded delimiter like in:
+%D
+%D \starttypen
+%D \def\startcommand#1\stopcommand%
+%D {... #1 ...}
+%D \stoptypen
+%D
+%D In many cases the \type{\start}||\type{\stop} pair is
+%D defined at format generation time or during a job. This
+%D means that we cannot hardcode the \type{\stop} criterium.
+%D Only after completely understanding \type{\csname} and
+%D \type{\expandafter} I was able to to implement a solution,
+%D starting with:
+%D
+%D \starttypen
+%D \grabuntil{stop}\command
+%D \stoptypen
+%D
+%D This commands executed, after having encountered
+%D \type{\stop} the command \type{\command}. This command
+%D receives as argument the text preceding the \type{\stop}.
+%D This means that:
+%D
+%D \starttypen
+%D \def\starthello%
+%D {\grabuntil{stophello}\message}
+%D
+%D \starthello Hello world!\stophello
+%D \stoptypen
+%D
+%D results in: \type{\message{Hello world!}}.
+
+\def\dograbuntil#1#2%
+ {\long\def\next##1#1{#2{##1}}\next}
+
+\def\grabuntil#1%
+ {\expandafter\dograbuntil\expandafter{\csname#1\endcsname}}
+
+%D The next command build on this mechanism:
+%D
+%D \starttypen
+%D \processbetween{string}\command
+%D \stoptypen
+%D
+%D Here:
+%D
+%D \starttypen
+%D \processbetween{hello}\message
+%D \starthello Hello again!\stophello
+%D \stoptypen
+%D
+%D leads to: \type{\message{Hello again!}}. The command
+%D
+%D \starttypen
+%D \gobbleuntil\command
+%D \stoptypen
+%D
+%D is related to these commands. This one simply throws away
+%D everything preceding \type{\command}.
+
+\long\def\processbetween#1#2%
+ {\setvalue{\s!start#1}%
+ {\grabuntil{\s!stop#1}{#2}}}
+
+\def\gobbleuntil#1%
+ {\long\def\next##1#1{}\next}
+
+%D \macros
+%D {groupedcommand}
+%D {}
+%D
+%D Commands often manipulate argument as in:
+%D
+%D \starttypen
+%D \def\doezomaarwat#1{....#1....}
+%D \stoptypen
+%D
+%D A disadvantage of this approach is that the tokens that
+%D form \type{#1} are fixed the the moment the argument is read
+%D in. Normally this is no problem, but for instance verbatim
+%D environments adapt the \CATCODES\ of characters and therefore
+%D are not always happy with already fixed tokens.
+%D
+%D Another problem arises when the argument is grouped not by
+%D \type{{}} but by \type{\bgroup} and \type{\egroup}. Such an
+%D argument fails, because the \type{\bgroup} is een as the
+%D argument (which is quite normal).
+%D
+%D The next macro offers a solution for both unwanted
+%D situations:
+%D
+%D \starttypen
+%D \groupedcommand {before} {after}
+%D \stoptypen
+%D
+%D Which can be used like:
+%D
+%D \starttypen
+%D \def\cite%
+%D {\groupedcommand{\rightquote\rightquote}{\leftquote\leftquote}}
+%D \stoptypen
+%D
+%D This command is equivalent to, but more 'robust' than:
+%D
+%D \starttypen
+%D \def\cite#1%
+%D {\rightquote\rightquote#1\leftquote\leftquote}
+%D \stoptypen
+%D
+%D One should say that the next implementation would suffice:
+%D
+%D \starttypen
+%D \def\groupedcommand#1#2%
+%D {\def\BeforeGroup{#1\ignorespaces}%
+%D \def\AfterGroup{\unskip#2\egroup}%
+%D \bgroup\bgroup
+%D \aftergroup\AfterGroup
+%D \afterassignment\BeforeGroup
+%D \let\next=}
+%D \stoptypen
+%D
+%D It did indeed, but one day we decided to support the
+%D processing of boxes too:
+%D
+%D \starttypen
+%D \def\rightword%
+%D {\groupedcommand{\hfill\hbox}{\parfillskip\!!zeropoint}}
+%D
+%D .......... \rightword{the right way}
+%D \stoptypen
+%D
+%D Here \TEX\ typesets \type{\bf the right way} unbreakable
+%D at the end of the line. The solution mentioned before does
+%D not work here.
+%D
+%D \starttypen
+%D \long\unexpanded\def\groupedcommand#1#2%
+%D {\bgroup
+%D \long\def\BeforeGroup%
+%D {\bgroup#1\bgroup\aftergroup\AfterGroup}%
+%D \long\def\AfterGroup%
+%D {#2\egroup\egroup}%
+%D \afterassignment\BeforeGroup
+%D \let\next=}
+%D \stoptypen
+%D
+%D We used this method some time until the next alternative
+%D was needed. From now on we support both
+%D
+%D \starttypen
+%D to be \bold{bold} or not, that's the question
+%D \stoptypen
+%D
+%D and
+%D
+%D \starttypen
+%D to be {\bold bold} or not, that's the question
+%D \stoptypen
+%D
+%D This alternative checks for a \type{\bgroup} token first.
+%D The internal alternative does not accept the box handling
+%D mentioned before, but further nesting works all right. The
+%D extra \type{\bgroup}||\type{\egroup} is needed to keep
+%D \type{\AfterGroup} both into sight and local.

+
+\long\def\HandleNoGroup#1#2%
+ {\long\def\AfterGroup{#2\egroup}%
+ \bgroup\aftergroup\AfterGroup#1}
+
+%D These macros come together in:
+%D
+%D \starttypen
+%D \long\unexpanded\def\groupedcommand#1#2%
+%D {\def\dogroupedcommand%
+%D {\ifx\next\bgroup
+%D \let\next=\HandleGroup
+%D \else
+%D \let\next=\HandleNoGroup
+%D \fi
+%D \next{#1}{#2}}%
+%D \futurelet\next\dogroupedcommand}
+%D \stoptypen
+%D
+%D From the missing paragraph number one can deduce that the
+%D last macro is not the real one yet. I considered it a
+%D nuisance that
+%D
+%D \starttypen
+%D \kleur[groen]
+%D {as gras}
+%D \stoptypen
+%D
+%D was not interpreted as one would expect. This is due to the
+%D fact that \type{\futurelet} obeys blank spaces, and a
+%D line||ending token is treated as a blank space. So the final
+%D implementation became:
+
+\long\unexpanded\def\groupedcommand#1#2%
+ {\bgroup
+ \def\dogroupedcommand%
+ {\ifx\next\bgroup
+ \def\\{\egroup\HandleGroup{#1}{#2}}%
+ \else\ifx\next\blankspace
+ \def\\ {\egroup\groupedcommand{#1}{#2}}%
+ \else
+ \def\\{\egroup\HandleNoGroup{#1}{#2}}%
+ \fi\fi
+ \\}%
+ \futurelet\next\dogroupedcommand}
+
+%D Users should be aware of the fact that grouping can
+%D interfere with ones paragraph settings that are executed
+%D after the paragraph is closed. One should therefore
+%D explictly close the paragraph with \type{\par}, else the
+%D settings will be forgotten and not applied. So it's:
+%D
+%D \starttypen
+%D \def\BoldRaggedCenter%
+%D {\groupedcommand{\raggedcenter\bf}{\par}}
+%D \stoptypen
+
+%D \macros
+%D {checkdefined}
+%D {}
+%D
+%D The bigger the system, the greater the change that
+%D user defined commands collide with those that are part of
+%D the system. The next macro gives a warning when a command is
+%D already defined. We considered blocking the definition, but
+%D this is not always what we want.
+%D
+%D \starttypen
+%D \checkdefined {category} {class} {command}
+%D \stoptypen
+%D
+%D The user is warned with the suggestion to use
+%D \type{CAPITALS}. This suggestion is feasible, because
+%D \CONTEXT only defines lowcased macros.

+%D \macros

+%D {}
+%D
+%D Typesetting a paragraph in a special way can be done by
+%D first grabbing the contents of the paragraph and processing
+%D this contents grouped. The next macro for instance typesets
+%D a paragraph in boldface.
+%D
+%D \starttypen
+%D \def\remark#1\par%
+%D {\bgroup\bf#1\egroup}
+%D \stoptypen
+%D
+%D This macro has to be called like
+%D
+%D \starttypen
+%D \remark some text ... ending with \par
+%D \stoptypen
+%D
+%D Instead of \type{\par} we can of course use an empty line.
+%D When we started typesetting with \TEX, we already had
+%D produced lots of text in plain \ASCII. In producing such
+%D simple formatted texts, we adopted an open layout, and when
+%D switching to \TEX, we continued this open habit. Although
+%D \TEX\ permits a cramped and badly formatted source, it adds
+%D to confusion and sometimes introduces errors. So we prefer:
+%D
+%D \starttypen
+%D \remark
+%D
+%D some text ... ending with an empty line
+%D \stoptypen
+%D
+%D We are going to implement a mechanism that allows such open
+%D specifications. The definition of the macro handling
+%D \type{\remark} becomes:
+%D
+%D \starttypen
+%D \def\remark%
+%D {\BeforePar{\bgroup\bf}%
+%D \AfterPar{\egroup}%
+%D \GetPar}
+%D \stoptypen
+%D
+%D A macro like \type{\GetPar} can be defined in several
+%D ways. The recent version, the fourth one in a row,
+%D originally was far more complicated, but some functionality
+%D has been moved to other macros.
+%D
+%D We start with the more simple but in some cases more
+%D appropriate alternative is \type{\GotoPar}. This one leaves
+%D \type{\par} unchanged and is therefore more robust. On the
+%D other hand, \type{\AfterPar} is not supported.

+%D \macros
+%D {dowithpargument,dowithwargument}
+%D {}
+%D
+%D The next macros are a variation on \type{\GetPar}. When
+%D macros expect an argument, it interprets a grouped sequence
+%D of characters a one token. While this adds to robustness and
+%D less ambiguous situations, we sometimes want to be a bit
+%D more flexible, or at least want to be a bit more tolerant
+%D to user input.
+%D
+%D We start with a commands that acts on paragraphs. This
+%D command is called as:
+%D
+%D \starttypen
+%D \dowithpargument\command
+%D \dowithpargument{\command ... }
+%D \stoptypen
+%D
+%D In \CONTEXT\ we use this one to read in the titles of
+%D chapters, sections etc. The commands responsible for these
+%D activities accept several alternative ways of argument
+%D passing. In these examples, the \type{\par} can be omitted
+%D when an empty line is present.
+%D
+%D \starttypen
+%D \command{...}
+%D \command ... \par
+%D \command
+%D {...}
+%D \command
+%D ... \par
+%D \stoptypen
+%D
+%D We show two implementations, of which for the moment the
+%D we prefier to use the second one:
+%D
+%D \starttypen
+%D \def\dowithpargument#1%
+%D {\def\dodowithpargument%
+%D {\ifx\next\bgroup
+%D \def\next{#1}%
+%D \else
+%D \def\next####1 \par{#1{####1}}%
+%D \fi
+%D \next}%
+%D \futurelet\next\dodowithpargument}
+%D \stoptypen
+%D
+%D A second and better implementation was:
+%D
+%D \starttypen
+%D \def\dowithpargument#1%
+%D {\def\nextpar##1 \par{#1{##1}}%
+%D \def\nextarg##1{#1{##1}}%
+%D \doifnextcharelse{\bgroup}
+%D {\nextarg}
+%D {\nextpar}}
+%D \stoptypen
+%D
+%D We ended up with an alternative that also accepts en empty
+%D argument. This command permits for instance chapters to
+%D have no title.
+
+\def\dowithpargument#1%
+ {\def\nextpar##1 \par{#1{##1}}%
+ \def\nextarg##1{#1{##1}}%
+ \doifnextcharelse{\bgroup}
+ {\nextarg}
+ {\doifnextcharelse{\par}
+ {#1{}}
+ {\nextpar}}}
+
+%D The \type{p} in the previous command stands for paragraph.
+%D When we want to act upon words we can use the \type{w}
+%D alternative.
+%D
+%D \starttypen
+%D \dowithwargument\command
+%D \dowithwargument{... \command ...}
+%D \stoptypen
+%D
+%D The main difference bwteen two alternatives is in the
+%D handling of \type{\par}'s. This time the space token acts
+%D as a delimiter.
+%D
+%D \starttypen
+%D \command{...}
+%D \command ...
+%D \command
+%D {...}
+%D \command
+%D ...
+%D \stoptypen
+%D
+%D Again there are two implementations possible:
+%D
+%D \starttypen
+%D \def\dowithwargument#1%
+%D {\def\dodowithwargument%
+%D {\ifx\next\bgroup
+%D \def\next{#1}%
+%D \else
+%D \def\next####1 {#1{####1}}%
+%D \fi
+%D \next}%
+%D \futurelet\next\dodowithwargument}
+%D \stoptypen
+%D
+%D We've chosen:
+
+\def\dowithwargument#1%
+ {\def\nextwar##1 {#1{##1}}%
+ \def\nextarg##1{#1{##1}}%
+ \doifnextcharelse{\bgroup}
+ {\nextarg}
+ {\nextwar}}
+
+%D \macros
+%D {dorepeat,dorepeatwithcommand}
+%D {}
+%D
+%D When doing repetitive tasks, we stromgly advice to use
+%D \type{\dorecurse}. The next alternative however, suits
+%D better some of the \CONTEXT\ interface commands.
+%D
+%D \starttypen
+%D \dorepeat[n*\command]
+%D \stoptypen
+%D
+%D The value of the used \COUNTER\ can be called within
+%D \type{\command} by \type{\repeater}.
+%D
+%D A slightly different alternative is:
+%D
+%D \starttypen
+%D \dorepeatwithcommand[n*{...}]\command
+%D \stoptypen
+%D
+%D When we call for something like:

+%D {untextargument
+%D untexcommand}
+%D
+%D When manipulating data(bases) and for instance generating
+%D index entries, the next three macros can be of help:
+%D
+%D \starttypen
+%D \untextargument{...}\to\name
+%D \untexcommand {...}\to\name
+%D \stoptypen
+%D
+%D They remove braces and backslashes and give us something to
+%D sort.

+
+%D \macros
+%D {ScaledPointsToBigPoints,ScaledPointsToWholeBigPoints}
+%D
+%D One characteristic of \POSTSCRIPT\ and \PDF\ is that both
+%D used big points (\TEX's bp). The next macros convert points
+%D and scaled points into big points.
+%D
+%D \starttypen
+%D \ScaledPointsToBigPoints {number} \target
+%D \ScaledPointsToWholeBigPoints {number} \target
+%D \stoptypen
+%D
+%D The magic factor $72/72.27$ can be found in most \TEX\
+%D related books.
+

+ \scratchcounter=\scratchdimen
+ \advance\scratchcounter by \!!medcard
+ \divide\scratchcounter by \!!maxcard
+ \edef#2{\the\scratchcounter}}
+
+%D \macros
+%D {PointsToReal}
+%D
+%D Points can be stripped from their suffix by using
+%D \type{\withoutpt}. The next macro enveloppes this macro.
+%D
+%D \starttypen
+%D \PointsToReal {dimension} \target
+%D \stoptypen
+
+\def\PointsToReal#1#2%
+ {\scratchdimen=#1%
+ \edef#2{\withoutpt{\the\scratchdimen}}}
+
+%D \macros
+%D {dontleavehmode}
+%D
+%D Sometimes when we enter a paragraph with some command, the
+%D first token gets the whole first line. We can prevent this
+%D by saying:
+%D
+%D \starttypen
+%D \dontleavehmode
+%D \stoptypen
+%D
+%D This command is used in for instance the language module
+%D \type{lang-ini}.
+
+\def\dontleavehmode{\ifmmode\else$ $\fi}
+
+%D \macro
+%D {handletokens}
+%D
+%D With the next macro we enter a critical area of macro
+%D expansion. What we want is a macro that looks like:
+%D
+%D \handletokens some tokens\with \somemacro
+%D
+%D At first sight the next implementation will suffice, but
+%D running this one shows that we loose the spaces. This is no
+%D surprise because we grab arguments and spaces preceding those
+%D are just ignored.
+%D
+%D \starttypen
+%D \def\nohandletokens#1\end%
+%D {}
+%D
+%D \def\dohandletokens#1#2\end%
+%D {\ifx#1\endoftoken
+%D \expandafter\nohandletokens
+%D \else
+%D \docommando{#1}%
+%D \expandafter\dohandletokens
+%D \fi
+%D #2\end}
+%D
+%D \long\def\handletokens#1\with#2%
+%D {\let\docommando=#2\relax
+%D \dohandletokens#1\endoftoken\end}
+%D \stoptypen
+%D
+%D A second approach therefore grabs the indicidual characters
+%D by using \type{\afterassignment}, in which case the space is
+%D read in as space.
+%D
+%D \starttypen
+%D \def\dodohandletokens%
+%D {\ifx\next\end \else
+%D \docommando\next
+%D \expandafter\dohandletokens
+%D \fi}
+%D
+%D \def\dohandletokens%
+%D {\afterassignment\dodohandletokens\let\next= }
+%D
+%D \long\def\handletokens#1\with#2%
+%D {\let\docommando=#2%
+%D \dohandletokens#1\end}
+%D \stoptypen
+
+%D \macro
+%D {counttoken}
+%D
+%D For the few occasion sthat we want to know the number of
+%D specific tokens in a string, we can use:
+%D
+%D \starttypen
+%D \counttoken token\in string\to \count
+%D \stoptypen
+%D
+%D This macro, that for instance is used in \type{cont-tab},
+%D takes a real counter. The macro can be preceded by \type
+%D {\doglobal}.
+
+\def\counttoken#1\in#2\to#3%
+ {\redoglobal#3=0
+ \def\!!stringa{#1}%
+ \def\!!stringb{\end}%
+ \def\docounttoken##1% obeys {}
+ {\def\!!stringc{##1}%
+ \ifx\!!stringb\!!stringc \else
+ \ifx\!!stringa\!!stringc
+ \dodoglobal\advance#3 by 1
+ \fi
+ \expandafter\docounttoken
+ \fi}%
+ \docounttoken#2\end
+ \resetglobal}
+
+%D \macros
+%D {splitofftokens}
+%D
+%D Running this one not always gives the expected results.
+%D Consider for instance the macro for which I originally
+%D wrote this token handler.
+
+\long\def\splitofftokens#1\from#2\to#3%
+ {\ifnum#1>0
+ \scratchcounter=#1\relax
+ \def\dosplitofftokens##1%
+ {\ifnum\scratchcounter>0
+ \advance\scratchcounter by -1
+ \edef#3{#3##1}%
+ \fi}%
+ % \let#3=\empty % #3 can be #2, so:
+ \@EA\let\@EA#3\@EA\empty
+ \@EA\handletokens#2\with\dosplitofftokens
+ \else
+ \edef#3{#2}%
+ \fi}
+
+%D This macro can be called like:
+%D
+%D \startbuffer[example]
+%D \splitofftokens10\from01234567 890123456789\to\test [\test]
+%D \stopbuffer
+%D
+%D However, the characters that we expect to find in
+%D \type{\test} just don;t show up there. The reason for this
+%D is not that logical but follows from \TEX's sometimes
+%D mysterious way of expanding. Look at this:
+%D
+%D \startbuffer[next]
+%D \def\next{a} \edef\test{\next} [\test]
+%D \let\next=b \edef\test{\test\next} [\test]
+%D \let\next=c \edef\test{\next} [\test]
+%D \let\next=d \edef\test{\test\next} [\test]
+%D \let\next=e \@EA\edef\@EA\test\@EA{\test\next} [\test]
+%D \stopbuffer
+%D
+%D \typebuffer[next]
+%D
+%D Careful reading shows that inside an \type{\edef} macro's
+%D that are \type{\let} are not expanded!
+%D
+%D \haalbuffer[next]
+%D
+%D That's why we finally end up with a macro that looks ahead
+%D by using an assignment, this time by using
+%D \type{\futurelet}, and grabbing an argument as well. That
+%D way we can handle both the sentinal and the blank space.
+
+\def\dodohandletokens#1%
+ {\ifx\next\blankspace
+ \docommando{ }%
+ \fi
+ \ifx#1\end \else
+ \docommando{#1}%
+ \expandafter\dohandletokens
+ \fi}
+
+\def\dohandletokens%
+ {\futurelet\next\dodohandletokens}
+
+\long\def\handletokens#1\with#2%
+ {\let\docommando=#2% #2 can be \docommando itself
+ \dohandletokens#1\end}
+
+%D So our example finaly shows up as:
+%D
+%D \haalbuffer[example]
+
+\protect
+
+\endinput

+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. Non||commercial use is
+%C granted.
+
+%D The following macros are responsible for the interaction
+%D with \CONTEXT. These macros have proven their use. These
+%D macros are optimized as far as possible within of course,
+%D the know how of the author.
+%D
+%D In this module we also show some of the optimizations,
+%D mainly because we don't want to forget them and start doing
+%D things over and over again. If showing them has a learing
+%D effect for others too, we've surved another purpose too.
+
+%D \macros
+%D {abortinputifdefined}
+%D {}
+%D
+%D Because this module can be used in a different context, we
+%D want to prevent it being loaded more than once. This can be
+%D done using:
+%D
+%D \starttypen
+%D \abortinputifdefined\command
+%D \stoptypen
+%D
+%D where \type{\command} is a command defined in the module
+%D to be loaded only once.
+%D
+%D \starttypen
+%D \def\abortinputifdefined#1%
+%D {\ifx#1\undefined
+%D \let\next=\relax
+%D \else
+%D \let\next=\endinput
+%D \fi
+%D \next}
+%D \stoptypen
+%D
+%D This macro can be speed up in terms of speed as well as
+%D memory. Because this is a nice example of a bit strange
+%D command (\type{\endinput}), we spend some more lines on this.
+%D
+%D If we perform such actions directly, we can say:
+%D
+%D \starttypen
+%D \ifx\somecommand\undefined
+%D \let\next=\relax
+%D \else
+%D \let\next=\endinput
+%D \fi
+%D \next
+%D \stoptypen
+%D
+%D We need the \type{\next} because we need to end the
+%D \type{\fi}. The efficient one is:
+%D
+%D \starttypen
+%D \ifx\somecommand\undefined
+%D \else
+%D \expandafter\endinput
+%D \fi
+%D \stoptypen
+%D
+%D Because \type{\endinput} comes into action after the current
+%D line, we can also say:
+%D
+%D \starttypen
+%D \ifx\somecommand\undefined \else \endinput \fi
+%D \stoptypen
+%D
+%D When we define a macro, we tend to use a format which
+%D shows as besat as can how things are done. \TEX\ however
+%D stores the definitions as a sequence of tokens, so in fact
+%D we can use a formatted definition:
+
+\def\abortinputifdefined#1%
+ {\ifx#1\undefined \else
+ \endinput
+ \fi}
+
+%D which also works. Keep in mind that this is entirely due to
+%D the fact that \type{\endinput} after the line, i.e. at the
+%D end of the macro. We therefore can burry this primitive quite
+%D deep in code.
+
+%D And because this module implements \type{\writestatus}, we
+%D just say:
+
+\abortinputifdefined\writestatus
+
+%D Normally we tell the users what module is being loaded.
+%D However, the command that is needed for this is not yet
+%D defined.
+%D
+%D \starttypen
+%D \writestatus{laden}{Context Systeem Macro's (a)}
+%D \stoptypen
+
+%D \macros
+%D [beschermen]
+%D {protect,unprotect}
+%D {}
+%D
+%D We can shield macros from users by using some special
+%D characters in their names. Some characters that are normally
+%D no letters and therefore often used are: \type{@}, \type{!}
+%D and \type{?}. Before and after the definition of protected
+%D macros, we have to change the \CATCODE\ of these characters.
+%D This is done by \type{\unprotect} and \type{\protect}, for
+%D instance:
+%D
+%D \starttypen
+%D \unprotect
+%D \def\!test{test}
+%D \protect
+%D \stoptypen
+%D
+%D The defined command \type{\!test} can of course only be
+%D called upon when we are in the \type{\unprotect}'ed state,
+%D otherwise \TEX\ reads \type{\!} and probably complains
+%D loudly about not being in math mode.
+%D
+%D Both commands can be used nested, but only the \CATCODE\
+%D of the outermost level is saved. We make use of
+%D an auxilary macro \type{\doprotect} to prevent us from
+%D conflicts with existing macro's \type{\protect}. When
+%D nesting deeper than one level, the system shows the
+%D protection level.
+
+\newcount\protectionlevel
+
+\ifx\protect\undefined
+ \def\protect{\message{<too much protection>}}
+\fi
+
+\let\normalprotect=\protect
+
+%D Although we don't need the \type{%} after commands that
+%D don't take arguments, unless lines are obeyed, I decided
+%D to put it there as a reminder. I only mention this once.
+
+\def\unprotect%
+ {\ifnum\protectionlevel=0
+ \edef\doprotectcharacters%
+ {\catcode`@=\the\catcode`@\relax
+ \catcode`!=\the\catcode`!\relax
+ \catcode`?=\the\catcode`?\relax}%
+ \catcode`@=11
+ \catcode`!=11
+ \catcode`?=11
+ \let\protect=\doprotect
+ \fi
+ \advance\protectionlevel by 1
+ \ifnum\protectionlevel>1
+ \message{<unprotect \the\protectionlevel>}%
+ \fi}
+
+\def\doprotect%

+ \let\protect=\normalprotect
+ \fi
+ \ifnum\protectionlevel>1
+ \message{<protect \the\protectionlevel>}%
+ \fi
+ \advance\protectionlevel by -1\relax}

+%D Now it is defined, we can make use of this very useful
+%D macro.

+%D don't expand them before interpretation. Such commands can
+%D be enclosed with \type{\expanded}, like:

+%D \stoptypen
+%D
+%D Such situations occur for instance when \type{\alfa} is a
+%D commalist or when data stored in macros is fed to index of
+%D list commands. If needed, one should use \type{\noexpand}
+%D inside the argument. Later on we will meet some more clever

+%D \macros
+%D {doifnextcharelse}
+%D {}
+%D
+%D When we started using \TEX\ in the late eighties, our
+%D first experiences with programming concerned a simple shell
+%D around \LATEX. The commands probably use most at \PRAGMA,
+%D are the itemizing ones. One of those few shell commands took
+%D care of an optional argument, that enabled us to specify
+%D what kind of item symbol we wanted. Without understanding
+%D anything we were able to locate a \LATEX\ macro that could
+%D be used to inspect the next character.
+%D
+%D It's this macro that the ancester of the next one presented
+%D here. It executes one of two actions, dependant of the next
+%D character. Disturbing spaces and line endings, which are
+%D normally interpreted as spaces too, are skipped.
+%D
+%D \starttypen
+%D \doifnextcharelse {karakter} {then ...} {else ...}
+%D \stoptypen
+%D
+%D This macro differs from the original in testing on
+%D \type{\endoflinetoken}, which of course we have to define
+%D first. We also use \type{\localnext} because we don't want
+%D clashes with \type{\next}.
+
+\let\endoflinetoken=^^M
+
+\long\def\doifnextcharelse#1#2#3%
+ {\let\charactertoken=#1%
+ \def\!!stringa{#2}%
+ \def\!!stringb{#3}%
+ \futurelet\nexttoken\inspectnextcharacter}
+
+\def\inspectnextcharacter%
+ {\ifx\nexttoken\blankspace

+ \else\ifx\!!stringc\endoflinetoken
+ \let\localnext\reinspectnextcharacter
+ \else\ifx\nexttoken\charactertoken
+ \let\localnext\!!stringa
+ \else
+ \let\localnext\!!stringb
+ \fi\fi\fi
+ \localnext}
+
+%D This macro uses some auxiliary macros. Although we were able
+%D to program quite complicated things, I only understood these
+%D after rereading the \TEX book. The trick is in using a
+%D command with a one character name. Such commands differ from
+%D the longer ones in the fact that trailing spaces are {\em
+%D not} skipped. This enables us to indirectly define a long
+%D named macro that gobbles a space.
+%D
+%D In the first line we define \type{\blankspace}. Next we
+%D make \type{\:} equivalent to \type{\reinspect...}. This
+%D one||character command is expanded before the next
+%D \type{\def} comes into action. This way the space after
+%D \type{\:} becomes a delimiter of the longer named
+%D \type{\reinspectnextcharacter}. The chain reaction is
+%D visually compatible with the next sequence:
+%D
+%D \starttypen
+%D \expandafter\def\reinspectnextcharacter %
+%D {\futurelet\nexttoken\inspectnextcharacter}
+%D \stoptypen
+%D
+%D However complicated it may look, I'm still glad I stumbled
+%D into this construction.
+
+\def\:{\let\blankspace= } \:
+
+\def\:{\reinspectnextcharacter}
+
+\expandafter\def\: {\futurelet\nexttoken\inspectnextcharacter}
+
+%D \macros
+%D {setvalue,setgvalue,setevalue,setxvalue,
+%D letvalue,
+%D getvalue,
+%D resetvalue}
+%D {}
+%D
+%D \TEX's primitive \type{\csname} can be used to construct
+%D all kind of commands that cannot be defined with
+%D \type{\def} and \type{\let}. Every macro programmer sooner
+%D or later wants macros like these.
+%D
+%D \starttypen
+%D \setvalue {naam}{...} = \def\naam{...}
+%D \setgvalue {naam}{...} = \gdef\naam{...}
+%D \setevalue {naam}{...} = \edef\naam{...}
+%D \setxvalue {naam}{...} = \xdef\naam{...}
+%D \letvalue {naam}=\... = \let\naam=\...
+%D \getvalue {naam} = \naam
+%D \resetvalue {naam} = \def\naam{}
+%D \stoptypen
+%D
+%D As we will see, \CONTEXT\ uses these commands many times,
+%D which is mainly due to its object oriented and parameter
+%D driven character.
+
+\def\setvalue#1%
+ {\expandafter\def\csname#1\endcsname}
+
+\def\setgvalue#1%
+ {\expandafter\gdef\csname#1\endcsname}

+

+
+\def\resetvalue#1%

+
+%D \macros
+%D {donottest,unexpanded}
+%D {}
+%D
+%D When expansion of a macro gives problems, we can precede it
+%D by \type{\donottest}. It seems that protection is one of the
+%D burdens of developers of packages, so maybe that's why in
+%D e-\TeX\ protection will be solved in a more robust way.
+%D
+%D Sometimes prefixing the macro with \type{\donottest} leads
+%D to defining an auxiliary macro, like
+%D
+%D \starttypen
+%D \def\dosomecommand {... ... ...}
+%D \def\somecommand {\donottest\dosomecommand}
+%D \stoptypen
+%D
+%D This double definition can be made transparant by using
+%D \type{\protecte}, as in:
+%D
+%D \starttypen
+%D \unexpanded\def\somecommand{... ... ...}
+%D \stoptypen
+%D
+%D The protection mechanism uses:
+
+\def\dontprocesstest#1%
+ {==}
+
+\def\doprocesstest#1%
+ {#1}
+
+\let\donottest=\doprocesstest
+
+%D By the way, we use a placeholder because we don't want
+%D interference when testing on empty strings. Using a
+%D placeholder of 8~characters increases the processing time
+%D of simple \type{\doifelse} tests by about 10 \%. When we
+%D process the test, we have to remove the braces and
+%D therefore explictly gobble \type{#1}.
+
+%D The fact that many macros have the same prefix, could have
+%D a negative impact on searching in the hash table. Because
+%D some simple testing does not show differences, we just use:
+%D

+ \futurelet\next\dounexpanded}
+
+%D This one accepts the more direct \type{\def} and cousins
+%D as well as the \CONTEXT\ specific \type{\setvalue} ones.
+%D
+%D And so the definition in our example turns out to be:
+%D
+%D \starttypen
+%D \def\csname do\somecommand\endcsname{... ... ...}
+%D \def\somecommand{\donottest\csname do\somecommand\endcsname}
+%D \stoptypen
+%D
+%D In which \type{do\somecommand} is hidden from the user and
+%D cannot lead to confusion. It's still permitted to define
+%D auxiliary macros like \type{\dosomecommand}.
+%D
+%D When we are going to use e-\TEX, we'll probably end up
+%D redefining some commands, but we can probably keep the
+%D \type{\unexpanded} ones unchanged.
+
+%D \macros
+%D {doifundefined,doifdefined,
+%D doifundefinedelse,doifdefinedelse,
+%D doifalldefinedelse}
+%D {}
+%D
+%D The standard way of testing if a macro is defined is
+%D comparing its meaning with another undefined one, usually
+%D \type{\undefined}. To garantee correct working of the next
+%D set of macros, \type{\undefined} may never be defined!
+%D
+%D \starttypen
+%D \doifundefined {string} {...}
+%D \doifdefined {string} {...}
+%D \doifundefinedelse {string} {then ...} {else ...}
+%D \doifdefinedelse {string} {then ...} {else ...}
+%D \doifalldefinedelse {commalist} {then ...} {else ...}
+%D \stoptypen
+%D
+%D Every macroname that \TEX\ builds gets an entry in the hash
+%D table, which is of limited size. It is expected that e-\TeX\
+%D will offer a less memory||consuming alternative.
+
+%D Although it will probably never be a big problem, it is good
+%D to be aware of the difference between testing on a macro
+%D name to be build by using \type{\csname} and
+%D \type{\endcsname} and testing the \type{\name} directly.
+%D
+%D \starttypen
+%D \expandafter\ifx\csname NameA\endcsname\relax ... \else ... \fi
+%D
+%D \ifx\NameB\undefined ... \else ... \fi
+%D \stoptypen
+%D
+%D I became aware of this when I mistakenly testen the first
+%D one against \type{\undefined}. When \TEX\ build a name using
+%D \type{\csname} it automatically sets it to \type{\relax},
+%D which is definitely not the same as \type{\undefined}. The
+%D quickest way to check these things is asking \TEX\ to show
+%D the meaning of the names:
+%D
+%D \starttypen
+%D \expandafter\show\csname NameA\endcsname
+%D
+%D \show\NameB
+%D \stoptypen
+%D
+%D The main reason why this never will be a big problem is that
+%D when one uses the \type{\csname} way, one probably has to do
+%D with some macroname that always is dealt with that way.
+%D Confusion can however arise when one applies both testing
+%D methods to the same macroname. By the way, the assignment
+%D of \type{\relax} obeys grouping.
+
+%D The first one gets rid of \type{#1}, but still expands to
+%D something and the second one expands to \type{#1}. Because
+%D we accept arguments between \type{{}}, we have to get rid
+%D of one level of braces.
+%D
+%D Our first implementation of \type{\ifundefined} was
+%D straightforward and readable:
+%D
+%D \starttypen
+%D \def\ifundefined#1%
+%D {\expandafter\ifx\csname#1\endcsname\relax}%
+%D
+%D \def\doifundefinedelse#1#2#3%
+%D {\let\donottest=\dontprocesstest
+%D \ifundefined{#1}%
+%D \let\donottest=\doprocesstest#2%
+%D \else
+%D \let\donottest=\doprocesstest#3%
+%D \fi}
+%D
+%D \def\doifdefinedelse#1#2#3%
+%D {\doifundefinedelse{#1}{#3}{#2}}
+%D
+%D \def\doifundefined#1#2%
+%D {\doifundefinedelse{#1}{#2}{}}
+%D
+%D \def\doifdefined#1#2%
+%D {\doifundefinedelse{#1}{}{#2}}
+%D
+%D \def\doifalldefinedelse#1#2#3%
+%D {\bgroup
+%D \donetrue
+%D \def\checkcommand##1%
+%D {\doifundefined{##1}{\donefalse}}%
+%D \processcommalist[#1]\checkcommand
+%D \ifdone
+%D \egroup#2%
+%D \else
+%D \egroup#3%
+%D \fi}
+%D \stoptypen
+%D
+%D When this module was optimized, timing showed that the
+%D next alternative can be upto twice as fast, especially when
+%D longer arguments are used.
+
+\def\ifundefined#1%
+ {\expandafter\ifx\csname#1\endcsname\relax}
+
+\def\p!doifundefined#1%
+ {\let\donottest=\dontprocesstest
+ \expandafter\ifx\csname#1\endcsname\relax}

+ {\p!doifundefined{#1}%
+ \let\donottest=\doprocesstest
+ \else
+ \let\donottest=\doprocesstest#2%
+ \fi}
+
+%D Before we start using this variant, we used another one,
+%D which is even a bit faster. This one looked like:
+%D
+%D \starttypen
+%D \def\p!doifundefined%
+%D {\begingroup
+%D \let\donottest=\dontprocesstest
+%D \ifundefined}
+%D
+%D \def\doifundefinedelse#1#2#3%
+%D {\p!doifundefined{#1}%
+%D \endgroup#2%
+%D \else
+%D \endgroup#3%
+%D \fi}
+%D \stoptypen
+%D
+%D A even more previous version used \type{\bgroup} and
+%D \type{\egroup}. In math mode however, \type{$1{x}2$} differs
+%D from \type{$1x2$}. This can been seen when one compares the
+%D output of:
+%D
+%D \starttypen
+%D $\kern10pt\showthe\lastkern$
+%D $\kern10pt{\showthe\lastkern}$
+%D $\kern10pt\begingroup\showthe\lastkern\endgroup$
+%D \stoptypen
+%D
+%D When we were developing the scientific units module, we
+%D encountered different behavior in text and math mode, which
+%D was due to this grouping subtilities. We therefore decided
+%D to use \type{\begingroup} instead of \type{\bgroup}.
+%D Later, when we had optimized some macro's the grouped
+%D solution turned out to be unsafe when typesetting this
+%D documentation, especially when using \type{\globaldefs}.
+%D
+%D We still have to define \type{\doifalldefinedelse}. Watch
+%D the use of grouping, which garantees local use of the
+%D boolean \type{\ifdone}.

+%D
+%D Programming in \TEX\ differs from programming in procedural
+%D languages like \MODULA. This means that one --- well, let me
+%D speek for myself --- tries to do the things in the well
+%D known way. Therefore the next set of \type{\ifthenelse}
+%D commands were between the first ones we needed. A few years
+%D later, the opposite became true: when programming in
+%D \MODULA, I sometimes miss handy things like grouping,
+%D runtime redefinition, expansion etc. While \MODULA\ taught
+%D me to structure, \TEX\ taught me to think recursive.
+%D
+%D \starttypen
+%D \doif {string1} {string2} {...}
+%D \doifnot {string1} {string2} {...}
+%D \doifelse {string1} {string2} {then ...}{else ...}
+%D \stoptypen
+%D
+%D When expansion gives problems, we can precede the
+%D troublemaker with \type{\donottest}.
+%D
+%D This implementatie does not use the construction which is
+%D more robust for nested conditionals.
+%D
+%D \starttypen
+%D \ifx\!!stringa\!!stringb
+%D \def\next{#3}%
+%D \else
+%D \def\next{#4}%
+%D \fi
+%D \next
+%D \stoptypen
+%D
+%D In practice, this alternative is at least 20\% slower than
+%D the alternative used here. The few cases in which we
+%D really need the \type{\next} construction, often need some
+%D other precautions and or adaptions too.

+%D One could wonder why we don't follow the the same approach
+%D as in \type{\doifdefined} c.s.\ and use \type{\begingroup}
+%D and \type{\endgroup}. In this case, this alternative is
+%D slower, which is probably due to the fact that more meanings
+%D need to be restored.
+%D
+%D The in terms of memory more efficient alternative using a
+%D auxiliary macro also proved to be slower, so we definitely
+%D did not choose for:
+%D
+%D \starttypen

+%D {\let\donottest=\dontprocesstest

+%D When \type{#1} is empty, this macro scans list \type{#2} for

+%D if present. When \type{#1} is non empty and not in the list,
+%D the action related to \type{unknown} is executed. Both
+%D keywords must be at the end of list \type{#2}. Afterwards,
+%D the actually found keyword is available in
+%D \type{\commalistelement}. An advanced example of the use of

+%D
+%D Now what are those expansion commands doing there. Well,
+%D sometimes we want to compare actions that may consist off
+%D commands (i.e. are no constants). In such occasions we can
+%D use the a bit slower alternatives:
+
+\def\unexpandedprocessfirstactioninset{\dontexpandactions\processfirstactioninset}
+\def\unexpandedprocessaction {\dontexpandactions\processaction}
+\def\unexpandedprocessallactionsinset {\dontexpandactions\processallactionsinset}
+
+%D By default we expand actions:
+
+\def\expandactions%
+ {\let\expandedaction=\edef}
+
+\expandactions
+
+%D But when needed we convert the strings to meaningful
+%D sequences of characters.
+
+\def\unexpandedaction#1>{}
+
+\def\noexpandedaction#1#2%
+ {\def\convertedargument{#2}%

+
+\def\dontexpandactions%
+ {\let\expandedaction=\noexpandedaction}
+
+%D \macros
+%D {getfirstcharacter,firstcharacter}
+%D {}
+%D
+%D Sometimes the action to be undertaken depends on the
+%D next character. This macro get this character and puts it in
+%D \type{\firstcharacter}.
+%D
+%D \starttypen
+%D \getfirstcharacter {string}
+%D \stoptypen
+%D
+%D A two step expansion is used to prevent problems with
+%D complicated arguments, for instance arguments that
+%D consist of two or more expandable tokens.
+
+\def\dogetfirstcharacter#1#2\\%

+
+\def\getfirstcharacter#1%
+ {\edef\!!stringa{#1}%

+%D \macros
+%D {doifinstringelse}

+%D
+%D We can check for the presence of a substring in a given
+%D sequence of characters.
+%D
+%D \starttypen
+%D \doifinsetelse {substring} {string} {then ...} {else ...}
+%D \stoptypen
+%D
+%D An application of this command can be found further on.
+%D Like before, we first show some alternatives, like the one
+%D we started with:
+%D
+%D \starttypen
+%D \long\def\p!doifinstringelse#1#2#3#4%
+%D {\def\c!doifinstringelse##1#1##2##3\war%

+%D
+%D \def\doifinstringelse%
+%D {\ExpandBothAfter\p!doifinstringelse}
+%D \stoptypen
+%D
+%D After this we came to:
+%D
+%D \starttypen
+%D \def\p!doifinstringelse#1#2%
+%D {\def\c!doifinstringelse##1#1##2##3\war%

+%D {\ExpandBothAfter\p!doifinstringelse{#1}{#2}%
+%D #4%
+%D \else
+%D #3%
+%D \fi}
+%D \stoptypen
+%D
+%D And finaly it became:
+
+\def\v!ifinstringelse#1#2%
+ {\def\c!ifinstringelse##1#1##2##3\war%
+ {\csname\if##2@iffalse\else iftrue\fi\endcsname}%

+ #3%
+ \else
+ #4%
+ \fi}
+
+%D \macros
+%D {doifnumberelse}
+%D {}
+%D
+%D The next macro executes a command depending of the outcome
+%D of a test on numerals. This is probably one of the fastest
+%D test possible, exept from a less robust 10||step
+%D \type{\if}||ladder or some tricky \type{\lcode} checking.
+%D
+%D \starttypen
+%D \doifnumberelse {string} {then ...} {else ...}
+%D \stoptypen
+%D
+%D The macro accepts \type{123}, \type{abc}, \type{{}},
+%D \type{\getal} and \type{\the\count...}.
+
+\long\def\doifnumberelse#1#2#3%
+ {\getfirstcharacter{#1}%
+ \@EA\ifinstringelse\firstcharacter{1234567890}%
+ #2%
+ \else
+ #3%
+ \fi}
+
+%D Before we had \type{\ifinstringelse} available, we used:
+%D
+%D \starttypen
+%D \def\doifnumberelse#1%
+%D {\getfirstcharacter{#1}%
+%D \rawdoifinsetelse{\firstcharacter}{1,2,3,4,5,6,7,8,9,0}}
+%D \stoptypen
+
+%D A faster but less fail safe alternative is:
+%D
+%D \starttypen
+%D \dostepwiserecurse{0}{9}{1}
+%D {\@EA\uccode\@EA`\recurselevel=1}
+%D
+%D \long\def\doifnumberelse#1#2#3%

+%D \@EA\ifnum\@EA\uccode\@EA`\firstcharacter=1
+%D #2%
+%D \else
+%D #3%
+%D \fi}
+%D \stoptypen
+%D
+%D This one only works when the \type{\firstcharacter} is
+%D indeed a character. Numbers and strings of characters go
+%D all right, but arguments like \type{\relax} let things
+%D go wrong.
+
+%D \macros
+%D {makerawcommalist,
+%D rawdoinsetelse,
+%D rawprocesscommalist,
+%D rawprocessaction}
+%D {}
+%D
+%D Some of the commands mentioned earlier are effective but
+%D slow. When one is desperately in need of faster alternatives
+%D and when the conditions are predictable safe, the \type{\raw}
+%D alternatives come into focus. A major drawback is that
+%D they do not take \type{\c!constants} into account, simply
+%D because no expansion is done. This is no problem with
+%D \type{\rawprocesscommalist}, because this macro does not
+%D compare anything. Expandable macros are permitted as search
+%D string.

+%D \stoptypen
+%D
+%D Spaces embedded in the list, for instance after commas,
+%D spoil the search process. The gain in speed depends on the
+%D length of the argument (the longer the argument, the less
+%D we gain).

+%D When we process the list \type{a,b,c,d,e}, the raw routine
+%D takes over 30\% less time, when we feed $20+$ character
+%D strings we gain about 20\%. Alternatives which use
+%D \type{\futurelet} perform worse. Part of the speedup is
+%D due to the \type{\let} and \type{\expandafter} in the test.

+%D Assignments are the backbone of \CONTEXT. Abhorred by the
+%D concept of style file hacking, we took a considerable effort
+%D in building a parameterized system. Unfortunately there is a
+%D price to pay in terms of speed. Compared to other packages
+%D and taking the functionality of \CONTEXT\ into account, the
+%D total size of the format file is still very acceptable. Now
+%D how are these assignments done.
+%D
+%D Assignments can be realized with:
+%D
+%D \starttypen
+%D \doassign[label][variable=value]
+%D \undoassign[label][variable=value]

+%D
+%D and:
+%D
+%D \starttypen

+%D \stoptypen
+%D
+%D Assignments like \type{\doassign} are compatible with:
+%D
+%D \starttypen
+%D \def\labelvariable{value}
+%D \stoptypen
+%D
+%D We do check for the presence of an \type{=} and loudly

+%D It's possible to get an element from a commalist or a
+%D command representing a commalist.
+%D
+%D \starttypen
+%D \getfromcommalist [string] [n]
+%D \getfromcommacommand [string,\strings,string,...] [n]

+%D
+%D The difference betwee the two of them is the same as the
+%D difference between \type{\processcomma...}. The found string
+%D is stored in \type{\commalistelement}.
+%D
+%D We can calculate the size of a comma separated list by
+%D using:
+%D
+%D \starttypen
+%D \getcommalistsize [string,string,...]
+%D \getcommacommandsize [string,\strings,string,...]
+%D \stoptypen

+%D
+%D When working with delimited arguments, spaces and
+%D lineendings can interfere. The next set of macros uses
+%D \TEX' internal scanner for grabbing everything between
+%D arguments.
+%D
+%D \starttypen
+%D \dosingleargument\commando = \commando[#1]
+%D \dodoubleargument\commando = \commando[#1][#2]
+%D \dotripleargument\commando = \commando[#1][#2][#3]
+%D \doquadrupleargument\commando = \commando[#1][#2][#3][#4]
+%D \doquintupleargument\commando = \commando[#1][#2][#3][#4][#5]
+%D \dosixtupleargument\commando = \commando[#1][#2][#3][#4][#5][#6]
+%D \stoptypen
+%D
+%D These macros are used in the following way:
+%D
+%D \starttypen
+%D \def\dosetupsomething[#1][#2]%
+%D {... #1 ... #2 ...}
+%D
+%D \def\setupsomething%
+%D {\dodoubleargument\dosetupsomething}
+%D \stoptypen
+%D
+%D The implementation can be surprisingly simple and needs no
+%D further explanation, like:
+%D
+%D \starttypen
+%D \def\dosingleargument#1[#2]%
+%D {#1[#2]}
+%D \def\dotripleargument#1[#2]#3[#4]#5[#6]%
+%D {#1[#2][#4][#6]}
+%D \def\doquintupleargument#1%
+%D {\def\dodoquintupleargument[##1]##2[##3]##4[##5]##6[##7]##8[##9]%
+%D {#1[##1][##3][##5][##7][##9]}%
+%D \dodoquintupleargument}
+%D \stoptypen
+%D
+%D Because \TEX\ accepts 9~arguments at most, we have to use
+%D two||step solution when getting five or more arguments.
+%D
+%D When developing more and more of the real \CONTEXT, we
+%D started using some alternatives that provided empty
+%D arguments (in fact optional ones) whenever the user failed
+%D to supply them. Because this more complicated macros enable
+%D us to do some checking, we reimplemented the non||empty
+%D ones.

+%D \macros
+%D {dosingleempty,dodoubleempty,dotripleempty,
+%D doquadrupleempty,doquintupleempty}

+%D
+%D The empty argument supplying macros mentioned before, look

+%D \dotripleempty \command
+%D \doquadrupleempty \command
+%D \doquintupleempty \command

+%D \stoptypen
+%D
+%D So \type{\dodoubleempty} leades to:
+%D
+%D \starttypen
+%D \command[#1][#2]
+%D \command[#1][]
+%D \command[][]
+%D \stoptypen
+%D
+%D Depending of the generousity of the user. Afterwards one can
+%D use the \type{\if...argument} boolean. For novice: watch

+%D Setups can be optional. A command expecting a setup is
+%D prefixed by \type{\complex}, a command without one gets the
+%D prefix \type{\simple}. Commands like this can be defined by:
+%D
+%D \starttypen
+%D \complexorsimple {command}
+%D \stoptypen
+%D
+%D When \type{\command} is followed by a \type{[setup]}, then
+%D
+%D \starttypen
+%D \complexcommand [setup]
+%D \stoptypen
+%D
+%D executes, else we get
+%D
+%D \starttypen
+%D \simplecommand
+%D \stoptypen
+%D
+%D An alternative for \type{\complexorsimple} is:
+%D
+%D \starttypen
+%D \complexorsimpleempty {command}
+%D \stoptypen
+%D
+%D Depending on the presence of \type{[setup]}, this one
+%D leads to one of:
+%D

+%D Those who get the creeps of expansion may skip the next

+%D \type{\start}||\type{\stop} pairs with complicated
+%D arguments.
+%D
+%D We won't go into details here, but the general form of
+%D this using this command is:
+%D
+%D \starttypen
+%D \definestartstopcommand\somecommand\v!specifier{arg}{arg}%
+%D {do something with arg}
+%D \stoptypen
+%D
+%D This expands to something like:
+%D
+%D \starttypen
+%D \def\somecommand arg \startspecifier arg \stopspecifier%
+%D {do something with arg}
+%D \stoptypen
+%D
+%D The argumentss can be anything reasonable, but double
+%D \type{#}'s are needed in the specification part, like:
+%D
+%D \starttypen
+%D \definestartstopcommand\somecommand\v!specifier{[##1][##2]}{##3}%
+%D {do #1 something #2 with #3 arg}
+%D \stoptypen
+%D
+%D which becomes:
+%D
+%D \starttypen
+%D \def\somecommand[#1][#2]\startspecifier#3\stopspecifier%
+%D {do #1 something #2 with #3 arg}

+%C
+%C This module is part of the \CONTEXT\ macro||package and is
+%C therefore copyrighted by \PRAGMA. Non||commercial use is
+%C granted.
+
+%D We've build \CONTEXT\ on top of \PLAIN\ \TEX. Because we
+%D want to make the format file as independant as possible of
+%D machine dependant font encodings, we have to bypass the
+%D loading of fonts.
+%D
+%D Let's start at the beginning. Because \PLAIN\ is not yet
+%D loaded we have to define some \CATCODES\ ourselves.
+
+\catcode`\{=1 % left brace is begin-group character
+\catcode`\}=2 % right brace is end-group character
+\catcode`\#=6 % hash mark is macro parameter character
+
+%D We are going to report to the user what we are skipping.
+
+\def\skipmessage#1{\immediate\write16{skipping #1 in plain}}
+
+%D We want to be able to use the \type{\newsomething}
+%D declarations not only on the \type{\outer} level. This can
+%D be done by redefining \type{\outer} so we have to save its
+%D original meaning.
+
+\let\normalouter = \outer
+\let\outer = \relax
+
+%D We also want to postpone the loading of hyphenation patters,
+%D so we redefine and therefore save \type{\input}.
+
+\let\normalinput = \input
+\def\input #1 {\skipmessage{\string\input}}
+
+%D Finaly are going to we redefine some font specification
+%D commands and that's why we save them too. The redefinitions
+%D are straightforward because the macros have to do nothing
+%D but skipping.
+
+\let\normalskewchar = \skewchar
+\def\skewchar #1=#2 {\skipmessage{\string\skewchar}}
+
+\let\normaltextfont = \textfont
+\let\normalscriptfont = \scriptfont
+\let\normalscriptscriptfont = \scriptscriptfont
+
+\def\textfont #1=#2{\skipmessage{\string\textfont}}
+\def\scriptfont #1=#2{\skipmessage{\string\scriptfont}}
+\def\scriptscriptfont #1=#2{\skipmessage{\string\scriptscriptfont}}
+
+%D The redefinition of \type{\font} is a bit more complicated,
+%D because in version 3.14159 a scaled specification was
+%D introduced.
+
+\let\normalfont = \font
+
+\def\skipscaled scaled #1 {}
+
+\long\def\font#1=#2 #3%
+ {\ifx#3s%
+ \skipmessage{scaled \string\font}%
+ \let\next=\skipscaled
+ \else
+ \skipmessage{\string\font}%
+ \let\next=\relax
+ \fi
+ \next#3}
+
+%D Relaxing some font switching macros is needed because we
+%D don't want any error messages during loading. These
+%D unharmfull messages could be ingored.
+%D
+%D The next substitution is needed for determining
+%D \type{\p@renwd} in the macro \type{\bordermatrix}.
+
+\def\tenex#1%
+ {\skipmessage{used \string\tenex}\hskip8.75002pt}
+
+%D We need to define \type{\tenrm} for switching to
+%D \type{\rm}.
+
+\def\tenrm%
+ {\skipmessage{\string\tenrm}}
+
+%D In \CONTEXT\ all \PLAIN\ \TEX\ fonts are available, just
+%D like \type{\p@renwd}. We only postpone loading them until
+%D they are actually needed.
+
+%D By bypassing fonts, some definitions become less valid so
+%D we have to redefine them afterwards.
+%D
+%D \starttypen
+%D \let\normalbordermatrix=\bordermatrix
+%D
+%D \def\bordermatrix%
+%D {\bgroup
+%D \setbox0=\hbox{\getvalue{\textface\c!mm\c!ex}B}%
+%D \global\p@renwd=\wd0\relax
+%D \egroup
+%D \normalbordermatrix}
+%D \stoptypen
+
+%D Now we are ready for loading \PLAIN\ \TEX. Of couse we use
+%D \type{\normalinput} and not \type{\input}.
+
+\normalinput plain.tex
+
+%D We restore some redefined primitives to their old meaning.
+
+\let\font = \normalfont
+\let\skewchar = \normalskewchar
+\let\textfont = \normaltextfont
+\let\scriptfont = \normalscriptfont
+\let\scriptscriptfont = \normalscriptscriptfont
+\let\input = \normalinput
+\let\outer = \normalouter
+
+%D We reset some of the used auxiliary macro's to
+%D \type{\undefined}. One never knows what testing on them is
+%D done elsewhere.
+
+\let\skipmessage = \undefined
+\let\skipscaled = \undefined
+\let\normalfont = \undefined
+\let\normalskewchar = \undefined
+\let\normaltextfont = \undefined
+\let\normalscriptfont = \undefined
+\let\normalscriptscriptfont = \undefined
+\let\normalinput = \undefined
+\let\normalouter = \undefined
+
+%D We want a bit more statistics and some less logging info
+%D in the \type{log} file.

+% The TABLE macros are divided into sections, roughly according to
+% function:
+
+% Section Name Function
+% a Allocation Allocates storage registers for parameters.
+% f Format Reads format section; builds preamble for \halign;
+% processes \ReFormat command.
+% g Get Value Converts "spec"'s (as in spec_{LT}) to
+% corresponding "values"'s (as in value_{LT}).
+% h Hacks Utility macros; error messages; miscellaneous commands.
+% k Keys Definition and scanning of format keys.
+% n Numeric Macros for TABLE's numeric format.
+% s Struts Macros for struts.
+% t Tables Sets up \halign for table; end-of-row processing;
+% alternate vertical rules; spanning; horizontal
+% lines; stretching and shrinking; repositioning
+% commands.
+
+% The name of each internal macro begins with the prefix "\!t", the
+% "!" having category code 11, followed by the letter of the section
+% in which the macro is defined. For example, a macro beginning "\!th"
+% is defined in Section h (Hacks). There a few exceptions:
+% the general purpose macros "\!ttemp", "\!ttempa", "\!ttempb", and
+% "\!tnext" are repeatedly defined on the spot as the need arises.
+
+% External macros (and active characters) are defined in the following
+% sections:
+% Macro Section

+% \- t
+% \= t
+% \ActivateBarAndQuote h

+% Don't try to read the TABLE macros until after you've read the
+% TABLE manual. The internal documentation of the macros is
+% sketchy; you need the manual to understand what's going on.
+% You should also review the material on \halign s in the TeXbook,
+% since TABLE uses an \halign to perform its alignments.
+
+% In studying the TABLE macros, you should start by skimming the
+% macros in the "miscellaneous hacks", "error messages", and "loops"
+% subsections of Section h, as well as the "\GetValue" macro in
+% Section g; these macros are called many times by the other macros.
+% To continue with a "bottom-up" approach, read next Sections k,
+% f, and t. (Top-downers should reverse the order.) The other
+% Sections can be looked at as the need arises.

+% SECTION F: FORMAT
+% *********************************************************************
+
+% As explained in Section 3.3 of the manual, TABLE alternates each
+% of the user's "data" columns with a "rule" column; moreover, TABLE
+% places a "dummy data" column at the left and right of a table.
+% A table with n nominal data columns therefore actually has a
+% total of
+% n (nominal data columns)
+% +(n+1) (rule columns)
+% + 2 (dummy data columns)
+% ____
+% 2n+3
+% columns.
+
+% FORMATs job is to create an \halign preamble for the alignment
+% of these (2n+3) columns. The preamble consists of templates
+% for the various columns, strung together with &'s and interlaced
+% with \tabskip glue specifications.
+
+% FORMAT constructs the template for a nomimal data column according
+% to the user-specified format keys. As the keys are read from left
+% to right, the template is built up "from the inside out" (as
+% illustrated in Section 3.1.9 of the manual), the inner-most part
+% being the "#" sign. A "|" in the format terminates template
+% building; the completed template is adjoined to preamble along
+% with the template for the following rule column.
+
+% Minimum column widths, if specified, are implemented by creating
+% an "artificial row" with data entries of the form
+% \hskip <minimum column width>.
+% This row has zero height and depth and is completely invisible.
+
+

+% ALTERNATE VRULES
+% *********************************************************************
+
+% A '\|' can appear in a rule-column in place of a '|', '"', or '&'.
+
+% If '\|' is immediately followed by a blank, a string of digits, or
+% (...) [... had better be a <dimen>], a \vrule is placed in the
+% rule column; the thickness of the \vrule follows TABLE's usual
+% conventions. Be sure to put a blank after a string of digits.
+
+% If '\|' is immediately followed by a '*', a user-specified default
+% "pseudo"-rule is placed in the rule column. This P.R. is specified
+% by the parameterless macro \PseudoVrule. For example,
+% to place a "double rule" into a rule column, you could make the definition
+% \def\PseudoVrule{\hfil\vrule \hskip1pt \vrule\hfil}
+
+% If none of the above cases applies, a non-space token follows '\|':
+% that token is placed in the rule-column. To put a '*' in a
+% rule-column, enter '\|{*}'. '\|\PseudoVrule' has the same effect
+% as '\|*'.
