Loading units fails
by Michael Guravage 24 Apr '18

24 Apr '18

Dear list members, I do not know when this problem first appeared, I have not used the units package for a while, but merely invoking the package with the latest beta provokes an error. MWE: \usemodule[units] \starttext help \stoptext The attached log says there is a problem on line 42 of m-units.mkiv. Any help would be appreciated. -- With kind regards, Michael Guravage

Installing a specific version of context
by N. Raghavendra 24 Apr '18

24 Apr '18

I would like to install the version of context dated 2017.11.14. How can one do this? I tried sh first-setup.sh --context=2017.11.14 but it produces errors like rsync: change_dir "/current/context/2017.11.14" (in minimals) failed: No such file or directory (2) I'd appreciate suggestions about this. Thanks, Raghu. -- N. Raghavendra <raghu(a)hri.res.in>, http://www.retrotexts.net/ Harish-Chandra Research Institute, http://www.hri.res.in/

xmlpos not enough for me
by Hans van der Meer 24 Apr '18

24 Apr '18

The macro \xmlpos{#1} returns the position number of the current node in its parent. However, I would like to know the position number in its parent for the node with the same tag. An example of what I mean: <parent> <somenode></somenode > <node>inside it \xmlpos{#1} will return 2 but I would like 1> <somenode></somenode > <somenode></somenode > <node>inside it \xmlpos{#1} will return 5 but I would like 2> </parent> Can this be accomplished already or does it require a new API? dr.

Reproducible PDF output not working
by N. Raghavendra 24 Apr '18

24 Apr '18

Sometime ago, I asked here about reproducible PDF output, and was told about the --nodates option of context. It worked then, but doesn't seem to be working now, with a recent version of context. ---------------------------------------------------------------------- $ cat foo.tex \starttext Hello, world! \stoptext $ ( rm -f a b foo.log foo.pdf foo.tuc && \ context --nodates foo.tex && cp foo.pdf a && \ sleep 1 && \ context --nodates foo.tex && cp foo.pdf b ) > /dev/null && \ md5sum a b bdd1911005623a519f5ecb3dbcb8bc7b a 06157e2840c0758ca46d5e7f0be239ef b $ context --version [elided] mtx-context | current version: 2018.04.19 15:53 ---------------------------------------------------------------------- File `a' has the words "<pdfx:ID>foo.2018-04-24T01:49:47-19:00</pdfx:ID>", and file `b' has "<pdfx:ID>foo.2018-04-24T01:49:49-19:00</pdfx:ID>" at the corresponding position. Please tell me how to ensure that the PDF output depends only on the source, and not on the time the output is generated. Thanks, Raghu. -- N.

Question about paragraphs and hanging punctuation
by Tomas Hala 24 Apr '18

24 Apr '18

Hi all, I used together hanging punctuation and define/setup paragraphs (tested on TL2017, current CTX). Unfortunately, inside the paragraph environment the hanging punctuation settings is ignored. Moreover, it seems that attributes inner= and command= works only for the first paragraph (column). The only one way I discovered is to write manually \setupalign[hz,hanging] command at the beginning of each column which is not very comfortable. I would like to ask you whether is here some way to set it generally. Or (better) to inherited it from the outer settings. Thanks in advance, Tomáš ------ Minimal example: \definefontfeature[default][default][protrusion=quality,expansion=quality] \starttext\mainlanguage[cz] \defineparagraphs[pokus][n=2] \setupparagraphs[pokus][1][width=10cc] %\setupparagraphs[pokus][1][width=10cc,inner={\setupalign[hz,hanging]}] % command=... \setupalign[hz,hanging] \setupbodyfont[modern,12dd] text \startsomepars text \nextsomepars text \stopsomepars text \stoptext

Characters allowed in macro names
by N. Raghavendra 22 Apr '18

22 Apr '18

I was wondering if it is alright to use underscores in the names of macros, e.g, as in the following file. It looks like \startsetups, and \def accept names with hyphens, underscores, and numerals, but \starttexdefinition doesn't tolerate any of them. 1. In general, what characters are allowed in macro names? Are Unicode characters admissible? 2. Apart from the fact that one can use whitespace freely in \starttexdefinition, is there any reason to prefer it over \def? Thanks, Raghu. ------------------------------------------------------------ \starttext \startsetups [hello-world_1] Hello, world 1! \stopsetups \setups [hello-world_1] \def\hello-world_2{Hello, world 2!} \hello-world_2 \starttexdefinition helloWorld Hello, world! \stoptexdefinition \helloWorld %% Doesn't work %% \starttexdefinition fooBar1 %% Foo, bar 1! %% \stoptexdefinition %% %% \fooBar1 %% Doesn't work %% \starttexdefinition foo_bar %% Foo, bar! %% \stoptexdefinition %% %% \foo_bar %% Doesn't work %% \starttexdefinition foo-bar %% Foo, bar! %% \stoptexdefinition %% %% \foo-bar \stoptext ------------------------------------------------------------ -- N.

Including part of a program source file
by N. Raghavendra 22 Apr '18

22 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 20 Apr '18

20 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.
