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

Images and Accessibility (ConTeXt LMTX 2025.04.28)
by Matthias Weber 11 May '25

Dear All, I am starting a new thread as requested. I can confirm that > > the following should work with current latest (from yesterday, > LuaMetaTeX 2.11.07 20250427 + ConTeXt LMTX 2025.04.28 14:29): > > \enabledirectives [backend.usetags=testing] > \setuptagging[state=start] > \setupstructure[state=start] > \setupbackend > [format=PDF/A-3a] > \setupbackend[format=pdf/ua-1] > \setupexternalfigures[location=default] > \starttext > \externalfigure[hacker][label={this is an image}] > > \startparagraph > a > \stopparagraph > \stoptext produces a PDF that passes the accessibility check in the current Adobe Acrobat. In particular, it passes the alternate text checks. Hovering over the image shows the alternate text in Acrobat. However, VoiceOver (on the Mac) does not read the alternate text; it completely ignores the existence of the image. In Preview, no alternate text is shown or read. So it seems that the only benefit is that readers with vision can see an alternate text... I don’t have access to a Windows machine, so I cannot test what other screen readers can do with this document. Thanks, Matthias

curl missing from Docker image -> install-modules does not work

Hello, installing modules into the docker image is not possible since the curl command is not part of the image.

TDM Reservation Protocol (TDMRep)
by Steffen Wolfrum 01 May '25

01 May '25

Hi, we just saw the Accessibility Directive, now there is another demand: the TDM protocol (concerning the reuse of protected works for AI training purposes). Is it possible to implement these TDM Metadata when producing PDF files with ConTeXt? This technique provides a way to embed the rightsholder's choice into a PDF file. (See «§6.6 TDM Metadata in PDF files»: https://www.w3.org/community/reports/tdmrep/CG-FINAL-tdmrep-20240510/#sec-p…) Steffen

cannot find fonts in a manual install; what did I miss
by damien＠thiriet.web4me.fr 30 Apr '25

30 Apr '25

Hello! Since OpenBSD has upgraded to 7.7, I performed a manual installation of LMTX standalone after upgrading to my new OS version. What I did: download cont-lmt.zip into /usr/local/context/tex/texmf-context/ mv /home/dthiriet/cont-lmt.zip . unzip cont-lmt.zip cd source/luametatex/ ./build.sh (ou si ça ne marche pas pour des raisons d’autorisation: sh build.sh) cp build/native/luametatex tex/texmf-openbsd-amd64/bin/ depuis $HOME mtxrun --generate mtxrun --script fonts --reload Everything compiles, but the fonts are not found: fonts > defining > font with asked name 'lmsans10-regular' is not found using lookup 'file' fonts > defining > unable to define 'lmsans10-regular' as 'modern-12pt-ss-tf-' fonts > defining > forced type 'otf' of 'latinmodern-math' not found fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mr-' fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mb-' fonts > 'fallback modern ss 12pt' is loaded When I search my texmf-context file, I cannot find these otf files, so the problem isn't that I put them in the wrong place. I compared with my previous context install, and I can see the difference is that in the former my tree looked like this /usr/local/context | |-- texmf-context/ |-- texmf-openbsd-amd64/ |-- texmf This texmf/ folder, which contains fonts/ (with lmodern otf files and so on) and web2c misses in my current tree. But the context-readme.txt AFAIU does not say anything about a texmf/ folder in the tree. What did I miss? Should I have downloaded another zip from pragma pages? Thanks, Damien
