Translation of ConTeXt interface
by Garulfo 30 Jun '20

30 Jun '20

Thanks a lot Wolfang for your answer. I have 5 additional questions... sorry. ----------------------------------------------------------- >> \placeFLOAT becomes \placerFLOAT >> \startplaceFLOAT becomes \debutplacerFLOAT >> \placerchemical becomes \placerchemical >> \startplacerchemical becomes \debutplacerchemical >\placefigure is a combination of the element "place" (\e!place) and the > variable "figure" (\v!figure) >\startplacefigure is a combination of the elements "start" (\e!start) >and "place" (\e!place) and the variable "figure" (\v!figure.) 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... ----------------------------------------------------------- I get another difficulty with \startitemize and \stopitemize the translation of the variable "itemize" has no impact on the setup-fr.pdf file produced with : context --interface=fr --global --result=setup-fr x-setups-overview.mkiv But, I just found that if I actually use the translated commands in a test.tex file, it just works. % interface=fr \debuttexte \debutlister \elem first \elem second \finlister \fintexte What should I do in order to have a setup-fr.pdf file that shows the translations actually available ? ----------------------------------------------------------- With the translation of the command textwidth, I can use "largeur=0.5\largeurtexte" (cool !) But this command is not listed in setup-fr.pdf. Is there a way to add these basic commands to setup-fr.pdf ? ----------------------------------------------------------- Math. I get the following error : fonts > preloading latin modern fonts (second stage) fonts > defining > font with asked name 'fichier' is not found using lookup 'file' fonts > defining > unknown font 'fichier', loading aborted I suppose that due to the translation of "file" to "fichier". It's OK when I switch back to - setupstrings cd:file ==> file - variables file ==> file How can I translate the variable "file" into fichier, without messing with fonts (and maybe other file related functions) ----------------------------------------------------------- > Delimited command are problematic (especially when they change > catcodes), e.g. \startluacode use \stopluacode as hard coded delimiter > for the environment. While it is easy to create a synonym for > \startluacode this isn't the case for \stopluacode because the > environment always look for \stopluacode as stopper and alternative > names are ignored. \startsection \stopsection and \startformula \stopformula seem OK. How can I identify the delimited commands that should not be translated in order to avoid this issue. ----------------------------------------------------------- Thanks again

Fwd: Continued fractions in ConTeXt
by Jairo A. del Rio 30 Jun '20

30 Jun '20

Hi list! I've tried adapting the following code for continued fractions: %https://tex.stackexchange.com/questions/73195/how-to-typeset-a-continued-fraction-in-the-following-format \documentclass{article}\usepackage{amsmath} \begin{document}\newcommand*{\cofrac}[2]{% {% \rlap{$\dfrac{1}{\phantom{#1}}$}% \genfrac{}{}{0pt}{0}{}{#1+#2}% }%}\[ a_0 + \cofrac{a_1}{ \cofrac{a_2}{ \cofrac{a_3}{ \genfrac{}{}{0pt}{0}{}{\ddots} }}}\]\end{document} As I could read from the mailing list, ConTeXt no longer supports \genfrac, so I've tried the following using \definemathfraction \definemathfraction[gefrac][cfrac] \setupmathfraction[gefrac][rule=no] \def\cofrac#1#2{% {% \rlap{\cfrac{1}{\displaystyle\phantom{#1}}}% \gefrac{}{\displaystyle\gefrac{#1+}{}#2}% }% } \def\cofracnorule#1#2{% {% \rlap{\gefrac{\displaystyle\phantom{1}}{\displaystyle\phantom{#1}}}% \gefrac{}{\displaystyle\gefrac{#1}{}#2}% }% } \def\endfrac#1{\cofracnorule{#1}{\phantom{1}}} \startTEXpage \startplacefigure[location=force,number=no] \externalfigure[cofrac.png] \stopplacefigure \startformula \alpha + \cofrac{\alpha'}{\cofrac{\alpha''}{\cofrac{\alpha'''}{{\endfrac{\ddots}}}}} \frac{1}{\alpha'''} \stopformula \stopTEXpage Mmm, superscripts and fraction rules superpose, so indeed something is wrong. Any ideas or references to a better result? I've attached the expected result (it's from Legendre's Théorie des nombres) and a normal fraction for comparison. Thank you very much. Jairo :)

Re: [NTG-context] CONTEXT for OpenBSD 6.7

I just want to be sure that files will soon be available and that no mistake slipped in when you uploaded the files. Thank you for all your work! Actually, I just generated installer zips for 6.7 as mOjca got it all working. We dropped 6.5 in the process. (At some point the garden can have these installer files too as they are just files with no further dependencies but there has to be a dns or web server entry for it then.)

Commands with arguments before in ConTeXt
by Jairo A. del Rio 30 Jun '20

30 Jun '20

I've read the following is not possible in TeX \def#1\macro{blabla#1} where arguments come before. The only partial exceptions are commands like \atop or \over, which are in fact primitives. Is there a way to do this in ConTeXt? Could it be a feature request for LuaMetaTeX? I've seen Hans experimenting a lot with new primitives and new possibilities for arguments, like #0 and co., so I ask in case it's not too nonsensical to propose it. Regards Jairo :)

missing command for xmlinfo in latest?
by Pablo Rodriguez 29 Jun '20

29 Jun '20

Dear list, I have the following sample: \startbuffer[demo] <document> text </document> \stopbuffer \startxmlsetups xml:demo:base \xmlsetsetup{#1}{document}{xml:demo:doc} \stopxmlsetups \xmlregistersetup{xml:demo:base} \startxmlsetups xml:demo:doc \xmlinfo{#1} \xmlflush{#1} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext It crashes with latest form 2020.06.29 19:47, because of the use of \xmlinfo and some undefined command. Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

Converting from LaTeX for PDF accessibility tagging?
by Alasdair McAndrew 29 Jun '20

29 Jun '20

Hello, I tried ConTeXt a few years ago, then gave up on it because of its wordiness and verbosity. The 2006 article on creating AMSTeX output in ConTeXt at https://www.ntg.nl/maps/34/06.pdf shows exactly what I mean: the LaTeX commands are small and neat; the ConTeXt commands are not. However, I need now to use ConTeXt for accessibility tagging, so I'm prepared to give it another try. And this means converting some LaTeX documents into ConTeXt. Is there a better way than using pandoc? I ran a LaTeX document through pandoc, but the result is certainly not fully "ConTeXt compliant", and generates errors instead of compiling. I can get easily lost on the ConTeXt site: the documentation is there in plenty, but seems hard to search. The main problem for me is mathematics and alignment: not just for equations, but for matrices and arrays. What I'd love - if it exists - is a document showing how to rewrite LaTeX into ConTeXt. Something like the above document, which is now 14 years old. I also notice that much of the contextgarden wiki is outdated. For example, on the use of ConTeXt in MikTeX, we read "As of end of June 2011 MikTeX is still (or again) non-functional." I'm aware that all of this is the work of dedicated and unpaid volunteers, so this is not a complaint! Just an observation. Anyway, as I say, my main issues are converting LaTeX into ConTeXt. and dealing with mathematics. Any pointers would be gratefully received! Thanks, Alasdair -- https://numbersandshapes.net

Footnotes in math mode
by Jairo A. del Rio 28 Jun '20

28 Jun '20

Hi list! I want to know how to properly use footnotes in math mode. The following: \starttext \startformula \int_{a}^{b} f(x) d x=\lim _{h=0}\left[\int_{a}^{c-h} f(x) d x+\int_{c+h}^{b} f(x) d x\right] \startfootnote Footnote \stopfootnote \stopformula \stoptext doesn't complain but it doesn't show the footnote either. So, I'm using the following workaround: \starttext \startformula \int_{a}^{b} f(x) d x=\lim _{h=0}\left[\int_{a}^{c-h} f(x) d x+\int_{c+h}^{b} f(x) d x\right]\note[mynote1] \stopformula \footnotetext[mynote1]{Cauchy s'occupe du cas...} \stoptext However, 1) I have to create notes every time and it's kinda annoying when a large amount of formulas are annotated (I've read somewhere it's bad practice to (ab)use footnotes in math writing, but I see this often in books from the 19th century or earlier), 2) the numbering is bold. Making the numbering normal rather than bold would be fine, but I want to know about a better solution. Thank you in advance Jairo :) PS: How to answer messages sent to the mailing list? I'm on Gmail and I have to wait until the Digest comes. However, I can see messages in mail-archive.com. It's a dumb question, but when I want to thank Hans, Wolfgang or Aditya (and everyone else) for an answer, or following a thread, I have to edit the whole Digest mail. Sorry if I've been ungrateful by not answering back. Thank you again.

LSP support
by Saša Janiška 28 Jun '20

28 Jun '20

Hello, yesterday while exploring features/plugins of Kakoune (https://kakoune.org/) editor I, naturally, asked about ConTeXt/LaTeX support and was told about TexLab project (https://github.com/latex-lsp/texlab) bringing LSP (https://microsoft.github.io/language-server-protocol/) support for LaTeX. Interestingly enough, by browsing through the tickets I've found the following issue: "ConTeXt support" (https://github.com/latex-lsp/texlab/issues/166) where one of the, afaict, main devs of the project replied with: "ConTeXt support is definitely in scope of this project. Our LaTeX parser does not rely on LaTeX specifics but a lot of the features like code completion rely on LaTeX specifics. Nevertheless, supporting ConTeXt is a lot of effort at the moment as I have never used ConTeXt before. Supporting the project structure of ConTeXt would probably be the first step. " Of course, I'm glad that TexLab project does provide LSP support and bringing it to the Kakoune editor as well, but I'm sure that many of you know that bringing ConTeXt support to TexLab would benefit users of **many** other editors since these today many most popular editors (Atom, Emacs, SublimeText, (neo)Vimn, VScode...) are having support for LSP. Unfortuantely, I'm ConTeXt noob and not speaking Rust, but just want to bring the information if there are people familiar with both about potential benefit for ConTeXt to get LSP support. Sincerely, Saša -- One who is not disturbed in mind even amidst the threefold miseries or elated when there is happiness, and who is free from attachment, fear and anger, is called a sage of steady mind.
