Including part of a program source file
by N. Raghavendra 21 Apr '18

21 Apr '18

I am writing some notes using ConTeXt, which involves displaying parts of some program source files. At present, I am manually cutting and pasting the parts into the ConTeXt file. Is it possible to make ConTeXt do that for me? I am thinking of including each part of the Coq sources between tags like this: ------------------------------------------------------------ $ cat src-file <tag-1> part_to_be_included_1 </tag-2> <tag-2> part_to_be_included_2 </tag-2> ------------------------------------------------------------ I would like to say something like \IncludePart{src-file}{tag-1} in my ConTeXt file to get part_to_be_included_1 at that place in the PDF output after I run `context'. I would appreciate any advice on how to go about this. Thanks, Raghu. -- N. Raghavendra <raghu(a)hri.res.in>, http://www.retrotexts.net/ Harish-Chandra Research Institute, http://www.hri.res.in/

Re: [NTG-context] Border matrix
by Fabrice L 19 Apr '18

19 Apr '18

Dear list, Some months ago, Hans wrote to this list (see below) a macro to do matrix showing outside the brackets some informations (like we usually do for Markov chains), but adapted some plain tex code, which worked in MKII). I have used with success this code since then, but some weeks ago, the behavior of Context had changed (probably something on my part; I have updated the installation, but nothing changed). The problem (I think) is linked to \unprotect \protect. When this code is put before the \starttext to the the cont-new-mkiv, the border matrix behave well, but a simple \eqalign like this: \startformula \eqalign{ & \lambda=5, \mu =5 \cr & \mu=8 \cr } \stopformula do not works is I replace « \lambda » by « \lambda_2 » for example. I have no idea what’s is going on. here is a minimal example where Hans’s code is before the \starttext: % ———————————————————————————————————————— \unprotect \def\math_border_NC_indeed {\gdef\math_border_NC{\aligntab}} \let\math_border_NC\math_border_NC_indeed \def\math_border_NR {\glet\math_border_NC\math_border_NC_indeed \cr} \unexpanded\def\math_border_matrix#1#2#3% adapted plain {\begingroup % \pushmacro\cr % \setbox\scratchbox\hbox\bgroup \mr B% \egroup \scratchdimenone\wd\scratchbox % \scratchdimentwo.2\bodyfontsize % \mathsurround\zeropoint % \def\NC{\math_border_NC}% \def\NR{\math_border_NR}% % \setbox\scratchboxone\vbox\bgroup \def\cr{% \crcr \noalign\bgroup \kern\scratchdimentwo \global\let\cr\endline \egroup }% \ialign{% \startimath\alignmark\alignmark\stopimath \hfil \kern\dimexpr\scratchdimentwo+\scratchdimenone\relax \aligntab \thinspace \hfil \startimath\alignmark\alignmark\stopimath \hfil \aligntab \aligntab \quad \hfil \startimath\alignmark\alignmark\stopimath \hfil \crcr \omit \strut \hfil \crcr \noalign{\kern-\baselineskip}% #3\crcr \omit \strut \cr }% \egroup \setbox\scratchboxtwo\vbox\bgroup \unvcopy\scratchboxone \global\setbox\globalscratchbox\lastbox \egroup \setbox\scratchboxtwo\hbox\bgroup \unhbox\globalscratchbox \unskip \global\setbox\globalscratchbox\lastbox \egroup \setbox\scratchboxtwo\hbox\bgroup \startimath \kern\dimexpr\wd\globalscratchbox-\scratchdimenone\relax \left#1\relax \kern-\wd\globalscratchbox \global\setbox\globalscratchbox\vbox\bgroup \box\globalscratchbox \kern\scratchdimentwo \egroup \vcenter\bgroup \kern-\ht\globalscratchbox \unvbox\scratchboxone \kern-\baselineskip \egroup \thinspace \right#2\relax \stopimath \egroup \null \thickspace \vbox\bgroup \kern\ht\globalscratchbox \box\scratchboxtwo \egroup % \popmacro\cr % \endgroup} \unexpanded\def\bordermatrix {\math_border_matrix()} \unexpanded\def\bbordermatrix{\math_border_matrix[]} \unexpanded\def\startbordermatrix #1\stopbordermatrix {\math_border_matrix(){#1}} \unexpanded\def\startbbordermatrix#1\stopbbordermatrix{\math_border_matrix[]{#1}} \let\stopbordermatrix \relax \let\stopbbordermatrix\relax % ———————— % Should there be a "\ptotect" ? %\protect % ———————— \starttext A plain border matrix : \startformula \bbordermatrix{ a & b & c & d \cr e & f & G & h \cr i & j & k & l \cr} \stopformula \startformula \startbbordermatrix \NC a \NC b \NC c \NC d \NR \NC e \NC f \NC G \NC h \NR \NC i \NC j \NC k \NC l \NR \stopbbordermatrix \stopformula \startformula \eqalign{ & \lambda=5, \mu =5 \cr % ———————— % Does not work if the next line is uncommented % & \lambda_1=5, \mu =4 \cr % ———————— & \mu=8 \cr } \stopformula \stoptext % ———————————————————————————————————————— Thanks for any help.

numberstopper in \setupcaptions
by Alan Braslau 19 Apr '18

19 Apr '18

Hello list members, I am not sure how to achieve the following functionality: Using \startplacefigure, I would like to place a number stopper *only* when the caption text is non-empty, i.e. Figure 1 Figure 2: A cow This would be achieved through \setupcaption [figure] using numberstopper= I believe (with perhaps a filter), but I am not sure of exactly how to do this, especially how to do this most elegantly. Thank you Alan

\startplacetable in \startcolumnset
by Jeong Dal 19 Apr '18

Hi, I used the following exam format well which was set by the help of Wolfgang long time ago. Recently I got a strange output when I used \startplacetable or \placetable in the \startcolumnset … \stopcolumnset. There is a strange number first and table in the next column. The output is OK if I comment out either \startcolumnset or \placetable. Is “\definecolumnset, \startcolumnset” still a good command? I couldn’t find it in the list of commands. Thank you for reading.

luatex 1.08
by Hans Hagen 19 Apr '18

19 Apr '18

Hi, We released luatex 1.08 beta which uses lua 5.3 and will be default on the garden as soon as mojca moves the bins to the right place. We don't expect many issues as we tested it for quite a while. The context current works on both 1.07 and 1.08 but of course at some point the beta might evolve towards using 1.08 features. We're now stepping up to 1.09 for ourselves and will probably release that around the ctx meeting, which then leads to 1.10 for tex live 2019.
