does the m-math module still exist? has core-math changed too much for m-math to catch up, or does a version exist somewhere that works with the latest release of CONTEXT? nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

TaBlE Issues
by Nikolai Weibull 02 Mar '04

02 Mar '04

Where can I find a comprehensive specification of the TaBlE module? My problem is that I want a paragraph environment in a column, but that doesn't seem to exist/work. In tabulate you can use 'p' in the template, and table doesn't complain when you use it but doesn't obide by it either. Am I missing something, for \starttable[|l|l|] \NC Something \NC Long description ... \NC\AR \stoptable makes for a very wide table (that goes off the paper). nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

A (not so good) solution for presentations by steps
by Otared Kavian 01 Mar '04

01 Mar '04

Hi all, Sometime ago a few of us (including me) bothered Hans in order to obtain from him a step by step presentation command. He cooked up very quickly the macros contained in "s-pre-50.tex", and that was enough for most of the things. However when one uses more sophisticated styles, the overlays in "s-pre-50.tex" do not work quite good. I wrote a few macros in plain TeX and used them in ConTeXt in order to have step by step presentations with the styles "s-pre-xx.tex". (For those who know the "Prosper" macro packages for LaTeX, I got actually my inspiration from "prosper"). I admit that someone can write better and more elegant macros using the hidden power of ConTeXt, but at this point I am unable to do this... So could anyone try the following macros and tell if the steps are satisfactory for them? Thanks: Otared K. %%%% Beginning of the macros %%K s-pre-steps.tex %%K %%K Here we use the plain \TeX\ command \phantom{} in order to have %%K some material appear step by step. %%K The structure is quite simple, but since I am not very %%K familiar with ConTeXt, I cannot write elegant code as does %%K Hans Hagen... %%K %%K An advantage is that the code can be used also in %%K plain TeX, in LaTeX and other macro-packages. %%K %%K Otared Kavian <otared.kavian(a)wanadoo.fr> %%K last modified March 1, 2004 %%K \newif\ifSteppingSlide \SteppingSlidetrue %%K this is when you want a step by step presentation %\SteppingSlidefalse %%K this is when you want to print the slides % \newcount\StepsCounter \StepsCounter=0 % \newcount\NumberOfSteps \NumberOfSteps=10 % \newcount\BeforeStepNumber \BeforeStepNumber=0 % %%K StepBetween[number1,number2]{material} will make "material" %%K appear between steps "number1" and "number2" \def\StepBetween[#1,#2]#3{% \ifSteppingSlide \ifnum#1>\StepsCounter \phantom{#3} \else \ifnum#2<\StepsCounter \phantom{#3} \else \relax #3 \fi \fi \else {#3} \fi} % %%K Step{number}{material} will make "material" %%K appear beginning with step "number" until "NumberOfSteps" \def\Step#1#2{\StepBetween[#1,\NumberOfSteps]{#2}} % %%K OnlyStep{number}{material} will make "material" %%K appear only on step "number" \def\OnlyStep#1#2{\StepBetween[#1,#1]{#2}} % %%K StepBefore{number}{material} will make "material" %%K appear only on all steps before "number" \def\StepBefore#1#2{ \global\BeforeStepNumber=#1\global\advance\BeforeStepNumber by -1 \StepBetween[0,\BeforeStepNumber]{#2}} % \long\def\SlideWithSteps#1#2{ \ifSteppingSlide \global\StepsCounter=0 \global\NumberOfSteps=#1 \MakeSteps{#2} \else #2 \fi} % \long\def\MakeSteps#1{\loop #1 \ifnum\StepsCounter<\NumberOfSteps \global\advance\StepsCounter by 1\vfill\eject \repeat \vfill\eject} % %%K This is the end of the macros %%K End of the macros "s-pre-steps.tex" %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%K Here is an example to test the above macros % \input s-pre-steps.tex \usemodule[pre-general] %%K I tried the macros for step by step presentation %%K with the following styles: \input s-pre-04.tex %\input s-pre-09.tex %\input s-pre-16.tex %\input s-pre-19.tex %\setupbodyfont[ss, 14.4pt] %% because I can't use other fonts %% due to a local problem on my Mac OS X, I guess \starttext \TitlePage {A simple presentation} \Topics {Today's talk} \Topic {First item} \input knuth \Topic {Second item} \input tufte \Subject {A subitem} \input knuth \Subject {Another subitem} \input tufte \Subject {Here are some steps} In the next slide we show some material appearing step by step.

\doifnextcharelse problem
by Nikolai Weibull 27 Feb '04

27 Feb '04

It seems that I can't get \definecomplexorsimpleempty to work right. The command I define works fine unless the simple version is called, in which case the first character in the body of the command is checked \doifnextcharelse[... which thus fails but in some manner eats it (even though it is output). The problem with the \doifnextcharelse is that the character it checks against is \catcode'd to \@@active, but it won't work when the character has been checked. Is there any way to fix this? I understand if my problem isn't that clear, so I've attached the module. The idea is to be able to write \startbnfgrammar <exp>: <num>. <num>: "0";"1". \stopbnfgrammar and this is then typeset as a table, but currently you're forced to write \startbnfgrammar[] <exp>: <num>. <num>: "0";"1". \stopbnfgrammar or the first < in <exp> gets eaten by \doifnextcharelse and the \def<{... won't be called causing problems down the line when the > is encountered, which expands into a \egroup which stops tex as there is no matching \bgroup. Now, is there any way to get \doifnextcharelse to properly deal with \catcode'd characters (such as my <) that it encounters when looking for other characters (such as the [ for optional arguments to commands)? I'd really like to resolve this, so any comments or tips are appreciated. Second, is there any good reference to programming TeX? I mean, one can figure out most stuff from reading CONTEXT's source for example, but it would be great to find out the exact implications of builtins such as \relax and so on. nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

Page-breakable framed text
by Mike Aizatsky 27 Feb '04

27 Feb '04

Hi! Is there a way to produce a page-breakable framed text? I've already spent several hours on this and still can't find the solution. Or, may be there's a better way to achieve the effect, shown in the sample? Sample: % interface=en output=pdftex \defineframedtext[procedure][frame=off, leftframe=on, rulethickness=.4mm] \def\StartProcedure{\startnarrower[2*left] \startprocedure \startitemize[n]} \def\StopProcedure{\stopitemize \stopprocedure \stopnarrower} \def\Step{\item} \starttext \dorecurse{20}{Some Text. Some Text. Some Text. } \StartProcedure \dorecurse{10}{ \Step\dorecurse{20}{Some Text.} } \StopProcedure \dorecurse{20}{Some Text. Some Text. Some Text. } \stoptext ===== MA __________________________________ Do you Yahoo!? Yahoo! Mail SpamGuard - Read only the mail you want. http://antispam.yahoo.com/tools

Can itemize calculate optimal label widths?
by Stefan Wachter 26 Feb '04

26 Feb '04

Hi all! Is there a possiblity to have itemize calculate the optimal label width itself? I have an itemize that has rather different labels, e.g.: \startitemize \sym{1.} An item \sym{2.} Another item \sym{103 a.} An item with a very broad label \stopitemize In this example the label "103 a." flows into the item text. It would be great if itemize would automatically use a label width that fits the broadest label. Thanks for your attention, --Stefan
