Re: [NTG-context] Translation of ConTeXt interface
So, I'm still doing something wrong, because changing the translation
of "figure" in "mult-def.lua" (in the part "variables"), only affect :
1- command "\startfigure \stopfigure"
2- "figure" in "\setuppageinjection" > alternative = figure buffer...
You have to provide your modified mult-def.lua file, otherwise there is
no way to check what's wrong.
Patch file : mult-def.lua.test1_figure.diff
context --make fr
context --interface=fr --global --result=setup-fr x-setups-overview.mkiv
Then the pdf file shows
- \demarrefigurefr as expected (p62)
but
- \placefigure instead of \placefigurefr (p190)
- \demarreplacefigure instead of \demarreplacefigurefr (p72)
the translation of the variable "itemize" has no impact on the
setup-fr.pdf file produced
But, I just found that if I actually use the translated commands in a
test.tex file, it just works.
Same as above, provide your translations.
Patch file : mult-def.lua.test2_itemize.diff
Input file : test2_itemize.tex
context --make fr
context --interface=fr --global --result=setup-fr x-setups-overview.mkiv
context test2_itemize.tex
setup-fr.pdf shows "\debutitemize ... \finitemize" page 41
instead of "\debutlister ... \finlister"
but the input file, with "\debutlister ... \finlister", works great.
There shouldn't be a problem with fonts because they use \s!file or
\s!name which aren't translated (unless you made the mistake and have
\c!file in your typescripts). It's possible there is a bug somewhere but
you have to provide a minimal example.
Understood, I am going to check.

Re: [NTG-context] error running wiki example with labels
The issue is the same after update of lmtx but the complaint differs.
I’m not sure the full command sequence that runs by vim, anyone else who knows
the internal default by vim in context mode?
However the result from commandline in vim
:!context %
works fine
but not when I run
:ConTeXt

None of the prefab solutions are used. The XML parser in ConTeXt is hand-written by Hans. Most (all?) of the TeX macros like \xmlfirst are in fact thin wrappers around lua code, see https://source.contextgarden.net/tex/context/base/mkiv/lxml-ini.lua However, these are currently not documented. Hans wrote the xml-mkiv manual with TeX users in mind, so there is very little documentation on the Lua side of things. I have plans myself to write that ‘missing chapter’ but there are a lot of other things on my list of todos as well. > What I need (in LMTX lua) to add (sub)nodes to the XML node (that I read with > xml.first()) because the data I get is broken and I need to fix it before I > can use it (and I cannot get good data) The easiest way is to add the correct > data to the XML and then use it in my code.

Regardless of whether it is doable in principle, this is not the intended use of the xml processing in ConTeXT. ConTeXt XML support is for Formatting, not Transformation. If you need to actually change the XML structure, I strongly advice to find a solution elsewhere. ConTeXt not only does formatting, but it tries to do this as efficiently and fast as possible. That means that if you want to modify a parsed tree, you will almost certainly also have to fix up external indices into that tree and you probably will have to write the lua mutation functions yourself as well. So, better look at some binding for libxml2 to some language you like, and then transform the XML beforehand into something you can confidently use as source for typesetting. Again: ConTeXt XML support is not meant for XML Transformations.

Hi, list! I've seen the following in Stack Exchange:
https://tex.stackexchange.com/questions/503208/define-macro-that-scans-ahead-for-super-and-or-subscript-absorbs-them-and-mo
The answer is:
\documentclass{article}\usepackage{amsmath}\usepackage{xparse}
\NewDocumentCommand{\mymathsym}{e{^_}}{%
x^{\mathrm{foo}\IfValueT{#1}{,#1}}_{\mathrm{bar}\IfValueT{#2}{,#2}}%}
\begin{document}
\begin{gather}\mymathsym \\\mymathsym^{\mathrm{extrasup}}
\\\mymathsym_{\mathrm{extrasub}}
\\\mymathsym^{\mathrm{extrasup}}_{\mathrm{extrasub}}
\\\mymathsym_{\mathrm{extrasub}}^{\mathrm{extrasup}} \end{gather}
\end{document}
Such a macro contextually defines a behavior for a subscript and a
superscript even if they aren't displayed in a specific order, so
\mymacro_{a}^{b}
\mymacro^{b}_{a}
have the same output, even if the intended behavior is not the typical
one (I could redefine it so subscripts change colors, for instance).
Although I could just port the macro using xparse-generic because it
works in ConTeXt too, how to define a macro like that the ConTeXt way,
i.e., using only ConTeXt macros?
