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 \unknown. 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. + +% todo: we can use \letter... here: + +\def\lesscharacter {<} +\def\morecharacter {>} + +\chardef\texescape = `\\ +\chardef\leftargument = `\{ +\chardef\rightargument = `\} + +%D \macros +%D {type} +%D +%D We define \type{\type} as a protected command. This command +%D has several invocations: grouped, wirt boundary characters, +%D and with font switches. + +% \starttyping +% normal: \par \type{xx<<..xx..<<xx <<xx>> >>..>>xx} \par \type<<....>> \par \type<<..<<xx>>..>> \par +% normal: \par \type{xx<..xx..<xx <slanted> >..>xx} \par \type{<....>} \par \type{<..<xx>..>} +% \setuptype[option=slanted] +% slanted: \par \type{xx<<..sl..<<xx <<sl>> xx>>..sl..>>xx} \par \type<<..xx..>> \par \type<<..<<sl>>..>> \par +% slanted: \par \type{xx<<..sl..<xx <sl> xx>..sl..>>xx} \par \type<<..xx..>> \par \type<<..<sl>..>> \par +% \setuptype[option=none] +% none: \par \type{xx<<..xx..<<xx <<xx>> >>..>>xx} \par \type<<....>> \par \type<<..<<xx>>..>> \par +% \stoptyping + +%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. This implementation went through +%D several live cycles. The final implementation looks a bit +%D further and treats the lone \type{<<} and \type{>>} a bit +%D different. The \type {\null} prevents ligatures, which +%D unfortunately turn up in Lucida fonts. + +%D The following lines show what happens when we set +%D \type {option=commands}. +%D +%D \startbuffer +%D \starttyping +%D test//test test/BTEX \footnote{test test test}/ETEX test +%D test//test test/BTEX \footnote{test test test}/ETEX test +%D test test test/BTEX \bf(nota bene)/ETEX test +%D test test test /BTEX \bf(nota bene)/ETEX test +%D \stoptyping +%D \stopbuffer +%D +%D % \bgroup\setuptyping[option=commands]\getbuffer\egroup +%D +%D this was keyed in as: +%D +%D \typebuffer + +\unexpanded\def\type{\dotype\empty} + +% not that fast but catches \type{\command} % nothing more after \command +% +% \setupcolors[state=start] +% \setuptype[option=TEX] +% \setupcolors[textcolor=red] +% +% The options \type{before=\startsolutionbackground } and +% \type{after=\stopsolutionbackground} take care of putting a frame, +% which can +% +% {\blue The options \type{before=\startsolutionbackground } and +% \type{after=\stopsolutionbackground} take care of putting a frame, +% which} can + +\def\resumecoloraftergroup + {\localstartcolor[\s!black]% + \localstartcolor[\maintextcolor]% + \aftergroup\localstopcolor + \aftergroup\localstopcolor} + +% the rather messy \type command + +\def\dotype#1% was \dotype + {\bgroup + \resumecoloraftergroup % a problem is that we can still be in color mode, tricky hack + \begstrut % new, enables leading space in \type { abc } at par start / begstrut else no hyphenation + \let\currenttypingclass\??ty + \edef\currenttyping{#1}% + \catcode`\<=\@@other + \catcode`\>=\@@other + \futurelet\next\dodotype} + +\def\dodotypeA + {\initializetype + \initializetypegrouping + \verbatimfont + \verbatimcolor + \afterassignment\protectfirsttype\let\next=} + +\def\dodotypeB + {\initializetype + \setupnotypegrouping + \verbatimfont + \verbatimcolor + \let\next=} + +\def\dodotypeC<#1% + {\initializetype + \verbatimfont + \verbatimcolor + \if#1<% + \@EA\setupalternativetypegrouping + \else + \@EA#1% + \fi} + +\def\dodotypeD#1% + {\initializetype + \verbatimfont + \verbatimcolor + \catcode`#1=\@@endgroup} + +\def\dodotype + {\ifx\next\bgroup + \@EA\dodotypeA + \else\if\next<% + \doifelse{\typingparameter\c!option}\v!none + {\@EAEAEA\dodotypeB}{\@EAEAEA\dodotypeC}% + \else + \@EAEAEA\dodotypeD + \fi\fi} + +% The next one is safe for: \def\xx#1{\type{#1}} \xx{\ifx} + +\let\protectedfirsttype\string % \relax for special cases + +\bgroup +\catcode`\<=\active +\catcode`\>=\active +\gdef\doprotectfirsttype + {\normalifx\next<% + \endrobusttest \let\next\relax + \normalelse\normalifx\next\bgroup + \endrobusttest \let\next\relax + \normalelse\normalifx\next\egroup % takes care of \type{} + \endrobusttest \let\next\relax + \normalelse\normalifx\next\activeleftargument + \endrobusttest \let\next\relax + \normalelse + \endrobusttest \let\next\protectedfirsttype + \normalfi\normalfi\normalfi\normalfi + \next} +\egroup + +\def\protectfirsttype + {\beginrobusttest + \futurelet\next\doprotectfirsttype} + +% Verbatim does not work when passed as an argument, so here is a +% workaround.
