The very latest ConTeXt update appears to have resolved any previous issues I was having with color profiles. My log file now reads, as I hoped it would> backend > profiles > profile specification 'Coated FOGRA39 (ISO 12647-2:2004)' loaded from '/home/julian/data/context/tex/texmf-context/colors/icc/context/colorprofiles.xml' backend > profiles > setting 'CoatedFOGRA39.icc' as default 'cmyk' color space backend > profiles > setting output intent to 'Coated FOGRA39 (ISO 12647-2:2004)' with id 'FOGRA39' for entry 1 Thank you! There is a new warning in the log file that I have not seen before (nothing to do with the above). Could someone explain its significance to me? I assume I don't really need to bother about it but I'd like to understand it. csname overload > warning, protection level 3, control sequence 'newcontextversion', properties 'permanent protected', file '/home/julian/data/context/tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl', line 16 (Line 16, BTW is simply \setuplayout ) It repeats a few times in different ways, e.g. csname overload > warning, protection level 3, control sequence 'starttitle', properties 'frozen instance protected', file './prd_Gering30-06-25.tex', line 285 Julian

Bookmark hierarchy
by John Was 04 Jul '25

04 Jul '25

Hello. I'm still in the newbie category with ConTeXt, and am getting to grips with bookmarking of PDFs for the first time ever. The following example gives the correct hierarchy of subordinated bookmarks - part, chapter, and section, each progressively indented in the bookmark column at the left. However, I don't want the parts to have numbers at all, and I want the chapters to be numbered 1, 2, etc. (not 1.1, 1.2, etc.). If I ever go live with ConTeXt, the sections won't have any numbers at all (and I can see how to set this up), but in this default example I would like them also to shift up one decimal place: 1.1., not 1.1.1, and so on. I'm guessing there's an option in \part that I should be invoking, but I don't immediately see what that is (there doesn't seem to be a \startpart...\stoppart to allow the relatively straightforward customization that we get with chapters and sections). Here is the example: \setupinteraction [state=start] \setupinteractionscreen [option=bookmark] \placebookmarks[part,chapter,section] \starttext \part[title=Introduction,bookmark=Introduction,number=off] \noheaderandfooterlines INTRODUCTION \page \noheaderandfooterlines \page[odd] \startchapter[title=First Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \startchapter[title=Second Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \part[title=PART II,bookmark=Part II,number=off] PART II \noheaderandfooterlines \page \noheaderandfooterlines \page[odd] \startchapter[title=Third Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \page[odd] \startchapter[title=Fourth Chapter] \noheaderandfooterlines \input tufte \startsection[title=First section] \input knuth \stopsection \startsection[title=Second section] \input zapf \stopsection \stopchapter \stoptext Best wishes John *🇪🇺 * Слава Україні! * 🇺🇦* <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free.www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

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

reading YAML with Lua
by Henning Hraban Ramm 03 Jul '25

03 Jul '25

Hi, is there already something to read a YAML file as a lua table in LuaMetaTeX? I didn’t find anything. My requirements are low, I just need to read some author data like: """ AstridLindgren: birth_year: '1907' death_year: '2002' name: Astrid Lindgren BTraven: birth_year: '1882' death_year: '1969' full_name: Bernhard Traven Torsvan name: B. Traven VolkerLudwig: birth_year: '1937' full_name: Eckart Hachfeld organization: GRIPS Theater name: Volker Ludwig """ Often, lyaml[1] is suggested, but that depends on libyaml (like a few other implementations) and looks far too heavy for that easy format. lua-yaml[2] is simpler. There’s even lua-tinyyaml[3] in CTAN. Do you have experience with any of them? I guess I’ll try the latter first.

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.

Lengthening/shortening paragraphs

Hello. Is there a ConTeXt equivalent for plain TeX's \loosness (which allows the program to lengthening a paragraph, or shorten it if the number is negative). At the final stages of a book this is often useful for getting rid of unsightly gaps.

To Any Software Users: Collective Identity and Software-Based Creative Practitioners
by Riviera Taylor 24 Jun '25

24 Jun '25

Dear list, I am writing to you as I recently published a Master's thesis upon graduating from the Experimental Publishing degree programme at the Piet Zwart Institute, Willem de Kooning Academy. 'To Any Software Users: Collective Identity and Software-Based Creative Practitioners' was written in ConTeXt and is licensed under a Cooperative Non-Violent Public License. The thesis puts forward the position that performance-oriented activities are integral to building positive sentiment amongst creative, software based collectives. I emphasise the importance of feminist and collaborative practices as a remedy against the deleterious effects that software can have on individuals. This stance is fleshed out in response to the apparent contradiction between the ideals of software on the one hand, and its susceptibility to offensive applications and violent appropriation on the other. The argument is re-iterated in the choice of a public license which prohibits aggressive, discriminatory and other malevolent uses of the text and source code. It occurs to me that such community building practices carry weight in this context. I am reminded, for example, of the placid atmosphere which arose during a soroban making workshop at the 18th Annual ConTeXt meeting last year. And I appreciated the conversation which ensued following the live coding x typesetting performance I gave at the same meeting. While I do not discuss these moments in the body of the text I found them thought-provoking. Structurally, the single-document algorithm was crafted over the course of several sleepless nights by me (another detrimental aspect of software which too many are familiar with: losing sleep...) It playfully refuses a \starttext ... \stoptext structure which generates a non-fatal error in the logs. The document is read by luametatex from top to bottom and utilises buffers in a reflexive, performance-oriented way. That is, the main.tex file passed to the luametatex programme gets overwritten during the runs; the buffers are saved to files and the computational medium is thus foregrounded. These actions demonstrate the ephemerality of the source code and invite a performative interpretation of ConTeXt- but enough about the workflow. I'm optimistic that parts of the source code could be useful to the ConTeXt distribution. For example, it was necessary to write code that might be useful as a basis for a Harvard referencing bibliographical style (based on London Southbank University's Harvard Referencing Style guidelines). To my understanding such a template is not a part of the distribution yet, but, for example, APA is. I think this would be a valuable contribution which could encourage or facilitate more arts-based researchers to engage with the ConTeXt software. I would like to offer my thanks to everyone involved in the development of ConTeXt! You can read the thesis here: https://project.xpub.nl/routers-are-computers/thesis.pdf and find the source code here: https://git.xpub.nl/XPUB/project.xpub.nl/raw/branch/master/routers-are-comp… Kind regards, Riviera

SlideTitle font in Simpleslide module
by Jeong Dal 24 Jun '25

24 Jun '25

Dear Wolfgang and Aditya, I’d like to ask about my problems since you know well about the fonts and the simpleslide module. I have used simpleslide module frequently without any problem, but not in this year. Today, I tried to make a slide using simple slide module again, but I have a problem. First, I define Noto CJK-KR as a bodyfont. Korean texts in the text has no problem. But Koreans used as a main Title and SlideTitles are not shown. The error messages are following: fonts > checking > char 실 (U+0C2E4) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing fonts > checking > char 용 (U+0C6A9) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing fonts > checking > char 적 (U+0C801) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing fonts > checking > char 수 (U+0C218) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing fonts > checking > char 학 (U+0D559) in font 'TeXGyrePagellaMath-Regular-2' with id 6: missing According to this log, it look for Korean characters in the math font which fails. If I set \definefont[BigFontOnehalf][NotoSansCJKkr-Bold sa 1.5] \definefont[BigFontTwo][NotoSansCJKkr-Bold sa 2] Then the following code has no problem. Of course, author, institution, and body texts are shown well as before. \setupTitle[title={\BigFontTwo 여기에도 수학이?}, author={정 달 영}, institution={숭실대학교}, date={}, ] \SlideTitle{\BigFontOnehalf 자주듣는 질문들} \leftaligned{\framed[]{\tfc 수학은 왜 배우나요?}}\vfill \midaligned{\framed[]{\tfc 수학은 누가 만들었나요?}}\vfill \rightaligned{\framed[]{\tfc 이거 어디다 써요?}}\vfill My question is that "Why it tries to use the math font for Title and SlideTitle?" Here is a simplified example. %font definition \definefontfamily[notoFont][rm][Noto Serif CJK KR] [ it={style:regular,features:{*,slanted}}, sl={style:regular,features:{*,slanted}}, bi={style:bold,features:{*,slanted}},force=yes] \definefontfamily[notoFont][ss][Noto Sans CJK KR] [ it={style:regular,features:{*,slanted}}, sl={style:regular,features:{*,slanted}}, bi={style:bold,features:{*,slanted}},force=yes] \definefontfamily[notoFont][tt][Noto Sans Mono CJK KR] [ it={style:regular,features:{*,slanted}}, sl={style:regular,features:{*,slanted}}, bi={style:bold,features:{*,slanted}},force=yes] %\definefontfamily[notoFont][math][Tex Gyre Termes Math] \definefontfamily[notoFont][math][Tex Gyre Pagella Math] \usemodule[simpleslides][style=Swoosh, font=, color=blue,] \setupTitle[color=darkblue] \setupbodyfont[notoFont,ss, \NormalSize] \setuppagenumbering[state=stop] \setupTitle[title={\BigFontTwo 여기에도 수학이? \crlf {\fancyOne Mathematics everywhere!}}, author={정 달 영}, institution={숭실대학교}, date={}, ] \setupfootertexts [\tfx FlexMath \hfill \pagenumber\ / \lastpage] \placeTitle \startcomponent \SlideTitle{\BigFontOnehalf 자주듣는 질문들} \null\vfill \leftaligned{\framed[]{\tfc 수학은 왜 배우나요?}}\vfill \midaligned{\framed[]{\tfc 수학은 누가 만들었나요?}}\vfill \rightaligned{\framed[]{\tfc 이거 어디다 써요?}}\vfill \stopcomponent

Text depth

Hello For some reason I'm having a lot of trouble getting the page to include precisely 40 lines of text (10.5 Baskerville with an interline depth of 12 points). On an experimental file with 6 full-depth pages and no footnotes, I find that the first three have 39 lines and the second three have the desired 40 lines. You will see from the code below that I have been tinkering a lot, but it ought to be a simple matter! Can someone let me know what I should be doing? Here's the code (and I have to desert my desk now till this afternoon so am not in a hurry for an answer!): \definepapersize[OUPoctavo][width=136mm, height=214mm]%should be 216! \setuppapersize[OUPoctavo][A4] % paper size, printed on A4 \definelayout[GHIL] [edge=48pt, edgedistance=6pt, margin=72pt, margindistance=6pt, topspace=48pt, header=12pt, headerdistance=3pt, textheight=480pt,%should be 480pt, height=522.6275pt, width=24pc, footerdistance=6pt, footer=12pt, % lines=40%this messes up position on the A4 page location=middle, marking=on, horoffset=0pt, veroffset=0pt, paper=OUPoctavo] \setuplayout[GHIL] Best wishes John *🇪🇺 * Слава Україні! * 🇺🇦* <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free.www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Processing time
by John Was 23 Jun '25

23 Jun '25

Hello I am using a very short experimental file of five pages to acquaint myself with ConTexT, and find that processing takes a long time (over a minute or sometimes over two minutes) because at every run it is checking on paths etc. - mainly verifying and searching for fonts. Is there some way to prevent this, either by a command within the file or by giving something after -- when I invoke ConText (which I do from the Windows command line)? I shall paste below a short section of a very long log (1452 lines) so that ConTexperts can see what I mean.

preventing next \par
by mf 20 Jun '25

20 Jun '25

Hello list, I remember having read something about this, but I can't remember where: I need to prevent the next \par. The context (lowercase) is XML typesetting, where sometimes I want to concatenate two paragraphs in a particular typesetting, while keeping the original structure of the document (two distinct paragraphs). To give you an idea, in XHTML it could be something like this: ----------- <p>This is a paragraph.<?injecttex \preventpar ?></p> <p>This is the next paragraph.</p> ----------- Massi

Alternate text for figures that includes math
by Matthias Weber 20 Jun '25

20 Jun '25

Dear All, When tagging an image, it looks like the provided alternative text is used verbatim. That means no TeX commands are interpreted, nor any math is being interpreted. Is it possible to serialize the math in an alternate text (as the tracker does with the non-ALT math in the example below)? I can do this manually, but my figures contain quite a bit of math, and it would be nice if alternate text for math is provided consistently throughout the document. Thanks, Matthias \usemodule[mathml] \enabledirectives [backend.usetags=testing] \setuptagging[state=start] \setupstructure[state=start] \setupbackend [format=PDF/A-3a] \setupbackend[format=pdf/ua-1] \setupexternalfigures[location=default] \setupnote[mathnote][location=page] \enabletrackers[math.textblobs] \starttext \placefigure [here] [] % label {} % legend {\externalfigure[cow][label={A cow, contemplating $e^{\pi i}+1=0$}]} % path A human, contemplating $e^{\pi i}+1=0$. \stoptext

Time stamp on PDFs
by John Was 20 Jun '25

20 Jun '25

I have figured out how to place a date stamp on my PDFs (outside of the printable area bounded by crop marks) but I would ideally like to include the time of processing as well. I don't see anything like the plain TeX primitive \time (and when out of curiosity I tried '\the\time' this returned a mysterious number - today it is '691' - which doesn't seem relevant).
