Hi, I uploaded a new lmtx. Some more adaptive magic ... I'm not sure how usefull it is but users always find ways to apply such things. I attached a test file.

New Tool: tree-sitter-context_en Parser
by Paul Mazaitis 23 Apr '22

23 Apr '22

Hi, everyone! I've been working on an updated tree-sitter parser for the ConTeXt file format. The parser has pretty good support for parsing a ConTeXt .tex file and producing a syntax tree for that file (and, optionally, highlighting). The parser also has support for using appropriate parsers for areas of the document that embed other languages or formats. For example: a tree-sitter parser for Lua code already exists, and this parser can call out to that parser to handle any properly demarcated Lua code (\startluacode ... \stopluacode) present in a ConTeXt document. A full list of supported inclusions (with or without available parsers), along with additional notes, are in the Garden: https://wiki.contextgarden.net/pm39_tree_sitter_parser ...and the repo for the tree-sitter-context_en parser itself is here: https://github.com/pmazaitis/tree-sitter-context_en Tree-sitter parsers support lots of language bindings with which to build tools; I've put together a very badly engineered format-aware spellchecker as a demo (may have trouble with Windows EOL encoding): https://github.com/pmazaitis/contextpyspell-demo Please, please do not use this demo in production. :) A massive caveat regarding OS support: So far this has been all developed and tested under MacOS, and seems to work pretty well in that environment. I've also tested running the parser on Linux (Ubuntu), and that was also fairly straight forward. In either case, Rust and a C compiler are required for directly using the parser (and you'll also need node/npm to rebuild the grammar itself, if you want to make any changes). I have a Windows 10 machine, and the development environment on it is a complete puzzle to me. I am learning, but: running this parser under Windows isn't something I've been able to get working. If you have Windows development experience, I'd be happy for any advice on how to support this software on that platform. A second, massive caveat for Windows support: this parser should be agnostic about how line endings are encoded, and I've done minimal testing, but it should have a lot more. Looking forward: - This parser is...lightly tested. (More testing of more domains would be helpful!) - This tooling should be useful for small utilities: a linter, a formatter, a better spellchecker? - This tooling should be useful for LSP support? Onward! -Paul

Centering figures that extend into the margin
by yann＠yannherklotz.com 20 Apr '22

20 Apr '22

Hi, I've been playing around with 'marginnote' layout similar to tufte's books. The main thing that I can't figure out is how to centre figures that extend into the margin. These should take over the whole page, but the content of the figure should be centred, which is normally the case in normal figures. Below is my try of defining a marginnote that does this, by calculating the textarea size and setting the width to that. However, I can't seem to then figure out how to center the externalfigure inside of the figure. Thanks in advance!

Need some hints to fix my standalon installation
by Christoph Hintermüller 20 Apr '22

20 Apr '22

Hi Have updated my standalone installation from one of the 2020 releases to the latest one running ./first-setup.sh --context=latest --modules=all Now i see the strange behavior that fraction in second equation is not typeset instead typesetting math aborts after typesetting the upper part of the fraction. A short example showing this is attached (pdf, tex, and log) Therefore i have the following questions - would it help to sacrifice the updated standalone installation and do a fresh install - What else i would have to check and probably fix to make the math working as expected - any thing else to change -- -- Christoph Hintermüller Dipl.-Ing.

embed source-file in pdf
by Heinrich Paeßens 20 Apr '22

Hi there just a quick question: Is there a command or package to embed the source-file (*.tex) into the resulting pdf-file, just like in LaTeX using package »embedall« <https://mirror.las.iastate.edu/tex-archive/macros/latex/contrib/embedall/em…>? Many thanks and kind regards Heinrich

Re: [NTG-context] embed source-file in pdf
by Heinrich Paeßens 20 Apr '22

Hi Pablo Many thanks. That is exactly what I need, ie. to deliver the source code embedded in the PDF. attachment works like a charm Rik pointed me — additionally — into the direction of being PDF/A compliant. PDF/A is possible with setupbackend\setupbackend[format={pdf/a-3a}] but needs fixing with acrobat-preflight to pass validation (in Acrobat and veraPDF). Just in case someone needs to archive longterm. https://en.m.wikipedia.org/wiki/PDF/A Kind regards Heinrich Sent from my iPhone > On 20.

xmlpos values doubled
by Ben Moon 20 Apr '22

20 Apr '22

Hello All, I'm trying to render a table stored in XML JATS format (https://jats.nlm.nih.gov/archiving/) and eventually want to use the <colgroup> tag to setup column aligning from the @align attribute, e.g., \setupTABLE [column] [\xmlpos{#1}] [align=\xmlatt{#1}{align}] Including \xmlpos{#1} I get double the value returned, i.e.: the first element in colgroup returns 2, the second returns 4 etc. Below is a MWE to show my issue. I show \xmlpos for each <col> tag in <colgroup> above the table, which returns 2, 4, 6, 8 but I expected 1, 2, 3, 4. Am I missing something or is there another way I could do this? ~~~~~~~~~~~~ \startbuffer[table] <table-wrap> <table> <colgroup> <col align="center" /> <col align="right" /> <col /> <col /> </colgroup> <thead> <tr> <th>H1 (centre)</th> <th>H2 (right)</th> <th>H3</th> <th>H4</th> </tr> </thead> <tbody> <tr> <td>A1</td> <td>A2</td> <td>A3</td> <td>A4</td> </tr> <tr> <td>B1</td> <td>B2</td> <td>B3</td> <td>B4</td> </tr> </tbody> </table> </table-wrap> \stopbuffer \startxmlsetups xml:tabletestsetups \xmlsetsetup{#1}{*}{-} % tables \xmlsetsetup{#1}{table-wrap|table}{xml:*} \xmlsetsetup{#1}{thead|tbody|tr|th|td}{xml:table:*} \xmlsetsetup{#1}{colgroup|col}{xml:*} \stopxmlsetups \xmlregistersetup{xml:tabletestsetups} \startxmlsetups xml:table-wrap \startplacetable % \contextversion \par \xmlflush{#1} \stopplacetable \stopxmlsetups \startxmlsetups xml:table \bTABLE \xmlflush{#1} \eTABLE \stopxmlsetups \startxmlsetups xml:colgroup \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:col \xmlpos{#1} \xmlatt{#1}{align}\par \stopxmlsetups \startxmlsetups xml:table:thead \bTABLEhead \xmlflush{#1} \eTABLEhead \stopxmlsetups \startxmlsetups xml:table:tr \bTR \xmlflush{#1} \eTR \stopxmlsetups \startxmlsetups xml:table:th \bTH \xmlflush{#1} \eTH \stopxmlsetups \startxmlsetups xml:table:tbody \bTABLEbody \xmlflush{#1} \eTABLEbody \stopxmlsetups \startxmlsetups xml:table:td \bTC \xmlflush{#1} \eTC \stopxmlsetups \xmlprocessbuffer{main}{table}{} ~~~~~~~~~~~~ All the best, Ben Ben Moon ben(a)themoons.uk

Math functions not typeset inside MetaPost
by śrīrāma 20 Apr '22

20 Apr '22

Hi Hans, [I am sending this again since the previous mails regarding were sent during the weekend]. I am on the most recent upload of LMTX [2022.04.15 20:20]. However, when I try to use math functions inside MetaPost strings, the function is not typeset correctly. Please consider the following MWE: \starttext \startMPcode draw textext("\m{\max_i x_i}"); \stopMPcode \stoptext which produces the output attached here as an image. Instead of the mfunction maxᵢ xᵢ some form of the string mathfunctionhandlelabel is typeset. I tried to inspect \math_function_handle_label [math-ini] and also mp-mlib and mlib-pps but could not figure out what is going wrong. I wonder if there is a backslash missing somewhere. I am a little worried since I use MetaFun in conjunction with maths and could not figure out what the issue is. Please see the original post by Dalyoung here: https://mailman.ntg.nl/pipermail/ntg-context/2022/105462.html Please advise. Thank you, Sreeram

Word wrap of 'part' titles
by Bruce Horrocks 19 Apr '22

19 Apr '22

In the MWE below the 'part' title is centred but on one line only and, because it is a long title, the beginning and end are lost off the sides of the page. If it were a 'chapter' title then I could insert '\\' to cause a line break at that point. However this does not seem to work for 'part'. Is there a way of making 'part' titles wrap the same way that 'chapter' titles do? % ---begin--- \define[2]\placePartTitle{\midaligned{#2}} \definehead [Part] [part] \setuphead[Part] [ placehead=yes, style={\tfd}, command=\placePartTitle, ] \starttext \startPart[title={A very long part title that needs to be wrapped manually}] Some body text \stopPart \stoptext %---end--- — Bruce Horrocks Hampshire, UK
