missing metadata in LMTX
by Pablo Rodriguez 18 Nov '25

18 Nov '25

Dear list, this issue has been bugging me for some time: \startbuffer[demo] <doc> <meta> <author>author</author> <title>title</title> </meta> <text> text </text> </doc> \stopbuffer \starttext \startxmlsetups xml:initialize \xmlsetsetup{#1}{code|meta|text}{xml:*} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:meta \setupinteraction [author={\xmltext{#1}{/author}}, title={\xmltext{#1}{/title}}] \stopxmlsetups \startxmlsetups xml:text \xmlflush{#1} \stopxmlsetups \setupinteraction[state=start] \xmlprocessbuffer{main}{demo}{} \stoptext With LuaTeX, I get PDF metadata. With LuaMetaTeX, I cannot get them. For both, I’m using current latest (from 2024.02.27 09:21). Could anyone confirm the issue or explain me what I am missing? Many thanks for your help, Pablo

Negative font slant broken with compact fonts
by Max Chernoff 06 Oct '25

06 Oct '25

Hi, Using the latest ConTeXt (2025.02.19), negative slants are broken with compact fonts. Example document: \definefontfeature[default][default][Slant=-1] \startTEXpage Hello, world! \stopTEXpage When compiled with "context", I get the error message tex error > tex error on line 1 in file ./context-negative-slant.tex: Scale factor (-1000) should be in the range 0..100000 [...] I'm going to use 0 instead of that illegal code value. but when compiled with "context --nocompactfonts", I get the correct result. Thanks, -- Max

Problem with the second \HL in the matrix
by Ursula Hermann 21 Jul '25

21 Jul '25

Dear List, After some work I have this example. \starttext \startformula \startmathmatrix [fences=parenthesis] \VL\NR \HL \NC \NC \NC \NC \NC \NC \VL \NR \stopmathmatrix \stopformula \stoptext My problem is, that after the second \VL the \HL goes on the left side, and is too long, and not on the right side. Should be as the first one, but shorter. Many thanks Uschi

Custom background color for \framed inside lmt_text
by Emanuel Han 05 Jul '25

05 Jul '25

I want my custom color rose_color to be applied for background color for \framed inside lmt_text. For fill fullcircle, it works. With predefined colors as green, it works. \starttext \startMPcode color rose_color; rose_color = 1/256(255,204,255); %not working draw lmt_text [text ="\framed[background=color,backgroundcolor=rose_color,frame=on, location=low]{a rose box}",]; %working draw lmt_text [text ="\framed[background=color,backgroundcolor=green,frame=on, location=low]{a green box}",] shifted (1cm,1cm); %working fill fullcircle scaled 2cm shifted (0,3cm) withcolor rose_color; \stopMPcode \stoptext

\setupwhitespace[default]
by Bruce Horrocks 03 Jul '25

03 Jul '25

Is default a valid option for \setupwhitespace? It's listed in the wiki page but gives an error when used, e.g. \starttext \input knuth \par\thinrule\par \setupwhitespace[big] \input knuth \par\thinrule\par \setupwhitespace[default] \input knuth \stoptext Wiki link: <https://wiki.contextgarden.net/Command/setupwhitespace> — Bruce Horrocks Hampshire, UK

Passing the name of an XML file to process via the command line
by Duncan Hothersall 03 Jul '25

03 Jul '25

Hello list. I feel this should be an easy question to answer but I couldn't find a hint. I have a ConTeXt file which pulls in an XML file for processing using the command \xmlprocessfile{mydomain}{myXMLfile.xml}{} I would like instead to call context with the XML file name in the command line (so that I can use the same ConTeXt setups on multiple XML sources). How can I do that? Many thanks. Duncan

PDFs for the visually impaired
by John Was 02 Jul '25

02 Jul '25

Visually impaired readers using an audio reader to access PDFs will want to have footnotes read out at the point of occurrence of the footnote cue, after which reading of the main text will resume. (Or some may wish to have the footnotes suppressed altogether, which ideally should be an option). Is that achievable in ConTeXt? I have no experience of InDesign, but it seems that this happens automatically with PDFs produced by that program: https://www.dropbox.com/scl/fi/mgpj0ae4xlr0609oqnlj5/GHIL-Bulletin-May-2025… I was sent the Bulletin as an example of how German Historical Institute volumes should be formatted in future for compliance with the latest Accessibility legislation.

VSCode support
by Hraban Ramm 30 Jun '25

30 Jun '25

I just installed the latest version of VSCodium (https://github.com/VSCodium/vscodium/releases) on my Linux laptop and needed a while to get the extension from texmf-context/context/data/vscode/extensions/context to work. Apparently, since 2024 or so, you can’t just symlink your own (or Hans’) code into ~/.vscode/extensions any more but "must" install via the marketplace or a .vsix file. I tried the first method from: https://mehmetbaykar.com/posts/how-to-install-vscode-extension-from-your-cu… … but "vsce package" fails for me (might be a version mismatch of node.js, still investgating, but I hate that whole ecosystem…) Finally I found out, just copying or symlinking /does/ work, if there’s no "extensions.json" in ~/.vscode-oss/extensions before. Otherwise you must add the following entry manually to this file: { "identifier":{"id":"context development team.context"}, "version":"1.0.0", "location":{"$mid":1,"path":"~/.vscode-oss/extensions/context","scheme":"file"}, "relativeLocation":"context" } @Hans: * Could you provide a .vsix file? * Does it make sense to run "mtxrun --script vscode --generate"? * Does it make sense to run "mtxrun --script vscode --lsfile"? * "mtxrun --script vscode --start" works only on Windows (if at all, at least not on Linux or MacOS). WRT the latter: "start" is a Windows command. The OS version of VSC is called as "codium" instead of "code". The extension is not called "cdt.context" but "context development team.context", only the generated version has "cdt.context" but also doesn’t install: codium --reuse-window --extensions-dir "/home/hraban/lmtx/tex/texmf-context/context/data/vscode/extensions" --verbose --force --install-extension cdt.context TRACE [File Watcher (node.js)] Request to start watching: /home/hraban/.config/VSCodium/User (excludes: <none> , includes: <all>, filter: <none>, correlationId: <none>),/home/hraban/.config/VSCodium/User/settings.json (ex cludes: <none>, includes: <all>, filter: <none>, correlationId: <none>) INFO CLI main { _: [], diff: false, merge: false, add: false, remove: false, goto: false, 'new-window': false, 'reuse-window': true, wait: false, help: false, 'extensions-dir': '/home/hraban/lmtx/tex/texmf-context/context/data/vscode/extensions', 'list-extensions': false, 'show-versions': false, 'install-extension': [ 'cdt.context'], 'pre-release': false, 'update-extensions': false, version: false, verbose: true, status: false, 'prof-startup': false, 'no-cached-data': false, 'prof-v8-extensions': false, 'disable-extensions': false, 'disable-lcd-text': false, 'disable-gpu': false, 'disable-chromium-sandbox': false, sandbox: false, telemetry: false, debugRenderer: false, 'enable-smoke-test-driver': false, logExtensionHostCommunication: false, 'skip-release-notes': false, 'skip-welcome': false, 'disable-telemetry': false, 'disable-updates': false, 'use-inmemory-secretstorage': false, 'disable-workspace-trust': false, 'disable-crash-reporter': false, 'skip-add-to-recently-opened': false, 'open-url': false, 'file-write': false, 'file-chmod': false, force: true, 'do-not-sync': false, 'do-not-include-pack-dependencies': false, trace: false, 'trace-memory-infra': false, 'preserve-env': false, 'force-user-env': false, 'force-disable-user-env': false, 'open-devtools': false, 'disable-gpu-sandbox': false, '__enable-file-policy': false, 'enable-coi': false, 'enable-rdp-display-tracking': false, 'no-proxy-server': false, 'no-sandbox': false, nolazy: false, 'force-renderer-accessibility': false, 'ignore-certificate-errors': false, 'allow-insecure-localhost': false, 'disable-dev-shm-usage': false, 'profile-temp': false, logsPath: '/home/hraban/.config/VSCodium/logs/20250628T133211' } Installing extensions...

Footnote style
by John Was 28 Jun '25

28 Jun '25

Hello. I haven't yet found options that would allow me to alter the style of footnote cues in the text (I would prefer slightly larger and slightly higher) or the positioning of the footnotes themselves: instead of the note numberse standing out to the left of the text area, my aim is to position them indented (by 8pt), with a fixed 4pt space after the note number before the text of the note begins. Is this possible? If there is a package that will let me have even more control, that would be excellent. The book series for which I want to use ConTeXt has always had traditional features such as fitting a short note within the break line of a previous longer note, centring two (or more) short notes at the foot of a page with a 24pt gap between each, adding a 3pt space at the end of a note which has overrun onto the next page, and so on. I can do all these in XeTeX but realize I may have to accept some compromise in ConTeXt. The one thing I think wouldn't be acceptable is the note numbers standing to the left of the text area. Then there is the question of tagging notes, but that can wait for another day.

Does Harfbuzz plugin (font-plugins) still work?
by Jairo A. del Rio 28 Jun '25

28 Jun '25

Hi, list! I've tested Harfbuzz with some examples from Devanagari and Chinese and I only get garbled text and replacement characters. MWE: \usemodule[fonts-plugins] \definefontfeature[harf] [mode=plug, features=harfbuzz, shaper=native, % script=deva ? ] \starttext % Other fonts make no difference \definedfont[file:FreeSerif.ttf*harf at 12pt] \startlines एक दश शत सहस्र लक्ष कोटि शङ्कु महाशङ्कु वृन्द महावृन्द पद्म महापद्म खर्व महाखर्व समुद्र ओघ महौघ \stoplines \stoptext And no, my question isn't about not using ConTeXt "devanagari-one" or "devanagari-two" features. Overall, Indic scripts just worked most times once the Harfbuzz plugin was enabled (either using a custom libharfbuzz or the system's one). Thank you in advance. Jairo
