Why is this description environment not showing the correct title?
by Joel 13 Feb '26

13 Feb '26

\definedescription[latexdesc][headstyle=bold, style=normal, align=flushleft, alternative=hanging, width=broad, margin=1cm] \starttext \latexdesc{1540} some event happened \latexdesc{1541} some other event happened \latexdesc{1542} some event happened quite different \stoptext I found the above code (the first line) in the ConTeXt Wiki, as a way to create the equivalent of a desc environment from LaTeX. The items inside {} should be bold, then there is a gap before the next text. I am using this to display a simple timeline. Though the formatting looks perfect, very strangely when I compile it, it changes all of the dates to say "1540" (or whatever date was used first). Why is it showing the wrong title on the desc environment? --Joel

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

context / auctex problem?
by hanneder＠staff.uni-marburg.de 24 Feb '25

24 Feb '25

Apologies for this question, which is probably an auctex problem. I have a new install of everything (LinuX, emacs, texlive) and the latest (?) context (ConTeXt ver: 2024.05.27 18:16 LMTX) installed in a separate directory. Running context from the commandline works fine, so I guess I did not misspell the path, but when running "Context All" from emacs, the error is: ----- Running `ConTeXt' on `context-test' with ``context --once --nonstop context-test.tex'' /bin/sh: Zeile 1: context: Kommando nicht gefunden. TeX Output exited abnormally with code 127 at Mon Jun 17 14:03:03 ------ I don't think the .emacs is at fault, it worked before the reinstall and contains, for instance: (setq-default TeX-master t) (setq TeX-parse-self t) (setq TeX-auto-save t) (setq ConTeXt-Mark-version "IV") Any ideas welcome, Jürgen --- Prof. Dr. Juergen Hanneder Philipps-Universitaet Marburg FG Indologie u.

serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

How to improve appearance of bars in frac, sqrt, etc. on screens?
by Ralph 07 Oct '24

07 Oct '24

Hello, I’m relatively new to ConTeXt (version 2024.05.31, LMTX, standalone) and really enjoy learning it so far, but I have one little problem with the appearance of horizontal bars in math mode. It seems the way ConTeXt displayed horizontal extensible bars in math mode some time ago (as used in \frac, \sqrt, \overbar, ...) was similar to the way LaTeX (PDFLaTeX and LuaLaTeX) and Plain TeX handled this, but it has changed since then. Instead of one bar there are now multiple characters attached to each other. This makes it look more consistent with the font, but unfortunately it doesn’t display well in any PDF viewer I’ve tried (on Linux, so I’ve not tried Adobe Acrobat Reader). The bars look dotted, I guess it’s due to anti-aliasing (the dots disappear when anti-aliasing is disabled, but then of course everything looks pixelated). Two screenshots are attached (different zoom levels in PDF viewer) so that you know what I’m talking about. Source: \setuppapersize[S3] \starttext \startformula \sqrt{a^2 + b^2} = \frac{1000 \cdot c}{1000} \stopformula \stoptext Is there a way to switch to the old bars for documents viewed mainly on screens, or is there any other way to improve their appearance? I couldn’t find any documentation on this, so I would be very thankful if somebody here could help out. Best, Ralph

Draw leftframe to a description
by Gerion Entrup 07 Oct '24

07 Oct '24

Hi, I want to typeset an "excurses" description that is marked with a leftframe. The problem is that it spans about multiple pages and has footnotes. Here is an MWE: ``` %% -> mwe-framedtext.pdf \defineframedtext[excursusbg][ frame=off, leftframe=on, rulethickness=1mm, framecolor=blue, toffset=0mm, % there is an offset anyways ] %% -> mwe-textbackground.pdf % \definetextbackground[excursusbg] [ % location=text, % background=color, % backgroundcolor=lightblue, % frame=on, % loffset=10cm, % seems to have no impact % ] \definedescription[excursus][ text={Excursus:\ }, alternative=top, headstyle=bold, margin=1cm, width=broad, before={\startexcursusbg}, after={\stopexcursusbg}, ] \starttext \input ward \startexcursus[title={A Knuth extract}] \input knuth \stopexcursus \input ward \startexcursus[title={A much longer Knuth extract}] \input knuth Sometimes, sentences have footnotes\footnote{Some footnote}. \input knuth \input knuth \stopexcursus \stoptext ``` See the attached PDFs for the different results. In principal, I would like the excurses typesetted like to solution with \defineframedtext. However, this does not work with pagebreaks. Additionally, the leftframe is too long (it begins above the "Excursus" text). I tried toffset to let the leftframe begin exactly at the "Excurses" text without success. The solution with \textbackground looks somewhat promising. It supports pagebreaks, but draws above footnotes and prints a small rectangle at the end of the excursus. I also didn't found a way to specify a leftframe only. Also, loffset seems to have no effect, here. Do I use the false environments? Do you know a better solution? Gerion

PDF/UA-2, WTPDF
by Henning Hraban Ramm 20 Sep '24

20 Sep '24

Quoting a post by Philipp Kiff, https://mastodon.social/@pkiff/112219488889350928: In amongst the release of PDF/UA-2 (PDF for Universal Accessibility) and the new Well-Tagged PDF (WTPDF) standard last month, some PDF professionals may have missed two other new resources that may help explain and view them: 1. Questions and Answers about Tagged PDF from PDF association 2. Acrobat Custom File Info Panels by Peter Wyatt Last month saw the release of PDF/UA-2 and the new Well-Tagged PDF (WTPDF) standard - neither of which revokes PDF/UA-1. And none of those are the same as PDF 1.7 vs 2.0. To many, the landscape of PDF specs may now seem littered with confusing acronyms and versions! For some help disentangling it all, the PDF association has a Questions and Answers about Tagged PDF: https://pdfa.org/resource/tagged-pdf-q-a/ In related news, Peter Wyatt released Acrobat Custom File Info Panels. This is a free extension for Acrobat that adds new panels to the XMP metadata shown when you view File > Properties in Acrobat Pro. The new panels allow you to view the additional conformance claims and dated revisions of ISO standards that can now be included in PDFs, but that aren't currently visible in the standard Acrobat panels. https://pdfa.org/discovering-pdf-metadata/ One thing I realized in reading through the new standards and looking at various sample files this week is that I should probably spend some time learning LaTeX! Both LaTeX and LibreOffice are already capable of producing PDF/UA-2 files, and with some tweaking, LaTeX can produce what appear to be really good WTPDF files. Kudos to both those development teams! https://github.com/latex3/tagging-project/discussions/72 Finally, in case you missed earlier posts from last month, here are links to the official sources for the two new PDF standards that these other resources relate to: 1. PDF/UA-2 https://pdfa.org/iso-14289-2-pdfua-2/ 2. Well-Tagged PDF (WTPDF) https://pdfa.org/wtpdf/

Hi, end of the month update: - we are still working on the math manual so updates there (we want the manual to stable for the upcoming meeting) - we also work on the export (some changes and additions there but we will conver that plus some new tools later when we're done, read: are satisfied with what browsers can handle sort of well) - wolfgang updated the setups (command definitions) so plenty of improvements and completion in there (he also did some quality assurance) - all kind of small thingies (some to be introduced at the upcoming meeting were as usual we also discuss development and priorities) - there are some new \setupalign options, like 'notwins', 'notoddlers' and 'noorphans' in case someone wants to be surprised as usual when we run into unforseen issues we'll fix it, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

combining float counters
by Henning Hraban Ramm 31 Jul '24

Hi, I defined new float types for special figure/caption placement, but would like to use the general figure counter. I didn’t find a setup for that. How can I do this? pseudocode: \setupfloat[myfigure][ counter=figure, ] Hraban
