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

month form \currentdate in Roman numerals
by Pablo Rodriguez 03 Mar '25

03 Mar '25

Dear list, I would like to get the current month in Roman numerals (just now, it would be XII for December). The best I get is: \currentdate[\cldcontext{converters['R'] (tonumber(os.date("\letterpercent m", os.date(os.time()))))}] This strikes me as too complex (even for someone who cannot code). Is there now simpler way to write that? Just in case it may be relevant, this is part of the full day reference. 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.

images with alt text
by Steffen Wolfrum 06 Feb '25

06 Feb '25

Hi, as publishing houses (at least in Germany) are forced to provide «alt text» with their PDF-publications (from June 2025 on), I need to know how «images with alternate text» (https://en.wikipedia.org/wiki/Alt_attribute) are typeset with ConTeXt LMTX. In HTML it looks like this: <img src="example.jpg" alt="Example text"> What is the equivalent in ConTeXt LMTX? Yours, Steffen

Error when running context --make after updating context (FreeBSD)

01 Feb '25

Hi folks, I receive the following error when running context --make command (after update via install.sh): lua error > lua error on line 18 in file file-mod.mklx: token call, execute: ...ext/tex/texmf-context/tex/context/base/mkxl/file-mod.lmt:78: attempt to call a nil value (field 'getrunstate') stack traceback: ...ext/tex/texmf-context/tex/context/base/mkxl/file-mod.lmt:78: in local 'code' ...ext/tex/texmf-context/tex/context/base/mkiv/util-lua.lua:97: in field 'loadedluacode' ...ext/tex/texmf-context/tex/context/base/mkiv/luat-env.lua:108: in field 'luafilechunk' ...ext/tex/texmf-context/tex/context/base/mkxl/luat-cod.lmt:82: in function 'lua.registercode' [ctxlua]:1: in main chunk <empty file> A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) Any clues as to what causes this error? System is FreeBSD 14.2 TIA and regards, PT

does \setuplayout[grid=yes] require \startformula[split=line] ?
by garulfo＠azules.eu 29 Jan '25

29 Jan '25

Hi, sorry for the potentially puzzling title. I try to figure out why \setuplayout[grid=yes] seems to insert a line break in a short formula. Is there a way of ensuring regular vertical alignment of the formula number without ‘split=line’ ?

\setupdelimitedtext and color parameter: only the second delimiter is colored

Is this the expected behaviour? From an observation from https://wiki.contextgarden.net/Text_blocks/Environments/Quotes#Directly \starttext \quote{Some text} \setupdelimitedtext [quote] [color=red] \quote{Some text} \setupdelimitedtext [quote] [symcolor=red] \quote{Some text} \stoptext

[ page setup ]

What would be the simple preferred way to define a document having not just odd and even pages but also alternating width is sets of two. e.g. two pages with width 118 mm followed by two pages of 178 mm followed by two pages with width 118 mm, ... all hints appreciated .Floris
