08 Nov '23

You’re invited to join on Wednesday, November 8th, 19:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! There will be no online meeting in September, since we’ll meet in Sibřina in person. And let’s discuss there (or here) if we should move the date. CU soon! (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban

Re: Wiki problem - labels missing from the main diagram on the Page Layout page
by Andres Conrado Montoya 07 Nov '23

A possible reason for this is that the use of xlink:href, the attribute used to render the text glyphs created by symbol elements in https://wiki.contextgarden.net/images/5/54/layout.svg, has been deprecated since SVG 2.0, as you can see in https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/xlink:href Instead, as the article recommends, just href should be used instead, and the xlink:href attribute can be preserved as a fallback for (very) old browsers. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

But how can I solve it? I think some lines in the module should be commented out. (An example directly in the module?) I thank you for any hint. Greetings Thomas

Several math features broke for me in new Debian version
by Kumar Appaiah 03 Nov '23

03 Nov '23

Dear Friends, I am a regular user of ConTeXt. A recent upgrade of ConTeXt in Debian broke things for me. The bug report is here: https://bugs.debian.org/1055233 but I have reproduced the gist here: Upon upgrading to ConTeXt 2023.05.05.20230730+dfsg-2, several math features seem to break for me. Here is an example: \starttext Hello world! \startformula X(f) = \startcases[align={right,left},distance=3pt] \NC T, \NC{} $|f| < \frac{1}{2T}$ \NR \NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR \stopcases \stopformula \stoptext The above works very well in 2021.03.05.20230120+dfsg-1+deb12u1 but gives me this error in 2023.05.05.20230730+dfsg-2: resolvers | formats | executing runner 'run luametatex format': /usr/bin/luametatex --jobname="./test.tex" --socket --shell-escape --fmt=/home/kumar/.texlive2023/texmf-var/luametatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/luametatex/cont-en.fmt --lua=/home/kumar/.texlive2023/texmf-var/luametatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/luametatex/cont-en.lui --c:currentrun=1 --c:fulljobname="./test.tex" --c:input="./test.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:texmfbinpath="/usr/bin" job > passes > version mismatch: 1.32 <> 1.33 system > system > ConTeXt ver: 2023.05.05 18:36 LMTX fmt: 2023.11.2 int: english/english system > system > 'cont-new.mkxl' loaded open source > level 1, order 1, name '/usr/share/texmf/tex/context/base/mkxl/cont-new.mkxl' system > beware: some patches loaded from cont-new.mkiv close source > level 1, order 1, name '/usr/share/texmf/tex/context/base/mkxl/cont-new.mkxl' system > files > jobname './test', input './test.tex', result './test' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > level 1, order 2, name './test.tex' fonts > preloading latin modern fonts (second stage) mathematics > tweak > 'LatinModernMath-Regular', size 6, math size 3, version 'Version 1.959' found, version 'Version 1.958' expected fonts > 'fallback modern rm 12pt' is loaded tex error > tex error on line 5 in file ./test.tex: Missing $ inserted <inserted text> $ <to be read again> \mathatom <macro> \math_atom_by_parameter_indeed #1->\mathatom \s!class \mathcodechecked {#1} <macro> \math_frac #1#*[#2]->\beginmathgroup \setlocalmathfractioncurrent {#1}\ifparameter #2\or \setupcurrentmathfraction [#2]\fi \edef \p_math_fraction_fences {\mathfractionparameter \c!fences }\math_atom_by_parameter \mathfractionparameter \bgroup \ifempty \p_math_f <to be read again> { <line 3.5> \NC T, \NC{} $|f| < \frac{ 1}{2T}$ \NR 1 \starttext 2 Hello world! 3 \startformula 4 X(f) = \startcases[align={right,left},distance=3pt] 5 >> \NC T, \NC{} $|f| < \frac{1}{2T}$ \NR 6 \NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR 7 \stopcases 8 \stopformula 9 \stoptext 10 I've inserted a begin-math/end-math symbol since I think you left one out.

Adobe Source Typescript With Design Sizes
by Vincent Hennebert 03 Nov '23

03 Nov '23

Hello there, I had mentioned this on a thread some (long) time ago, finally got around to finishing a first version of a typescript with the Adobe Source font family, in all its weight alternatives and design sizes (the latter being available in the Serif style only). Comments welcome. If it looks good I can upload it to the wiki, on the Typescripts_examples page I guess. (I have Questions For the Experts further down...) About Adobe Source ================== The fonts are available on GitHub [1]. They are the descendants of the Source {Serif,Sans,Code} Pro fonts described in the type-imp-source.mkiv typescript available in the ConTeXt distribution. Due to major changes, Serif Pro was renamed into Serif 4 in, well, its version 4 [2] (that’s the version that introduces design sizes, a.k.a. optical sizes), and Sans Pro was renamed into Sans 3 [3]. [1] https://github.com/adobe-fonts/ [2] https://github.com/adobe-fonts/source-serif/releases/tag/4.004R [3] https://github.com/adobe-fonts/source-sans/issues/192 Usage ===== Short version: store the attached typescript and its helper Lua files somewhere on your file system where ConTeXt will find them ($HOME/texmf for example), then use in your document: \setupbodyfont[adobesource] Long version: The default typescript name is adobesource (also available as adobesource-regular) and has design sizes enabled. Each weight is also available: adobesource-extralight, adobesource-light, etc., all the way to adobesource-black. There is also a medium weight, that selects the regular versions of Serif and Sans, but the medium version of Mono (just slightly bolder than the regular one, presumably for better on-screen rendering in terminals). Design sizes can be disabled by adding -nodesignsize- to the typescript name: adobesource-nodesignsize-extralight, etc. Finally, I thought it would be cool to over-engineer the typescript a little bit and provide direct access to the design sizes (in case one would want a narrower version for body text, or a bolder and more expanded version for titles, etc.). Here they are, again in all their weights: adobesource-caption-extralight, adobesource-smtext-light, adobesource-subhead, adobesource-display-bold, etc. The ‘regular’ design size is accessed by simply using adobesource-nodesignsize. Questions For the Experts ========================= To avoid a gigantic typescript file with a lot of duplication, I offloaded the font filename calculation to a Lua function (see attached adobesource.lua). I initially wanted to put the Lua code inside the typescript, but then I had all sorts of weird Lua compilation errors. The very same code works fine when included in a normal document though. Could it be that typescripts are processed in some special mode that doesn’t like Lua syntax? As a workaround, I put the code in an external file and require it from inside the typescript. In the goodies file, I use what I believe is the largest possible font size that can be used in ConTeXt (16,383pt) to select the Display design size. Otherwise, text above that size will fall back to the default, regular design size. Now, since I use the goodies file only when design sizes are enabled, I thought I could make it more robust by using AdobeSource4Display as a default, that is, for any size above 16.5pt. However, if I mix design sizes enabled and disabled in a document, the disabled one seems to be using the goodies file even though it’s not mentioned in the typescript. Any idea of why? For example: \usetypescriptfile[adobesource] \usebodyfont[adobesource] \setupbodyfont[adobesource-nodesignsize] \starttext This text is typeset in Display when Regular should be used. \switchtobodyfont[adobesource] This text is typeset in Regular with design sizes enabled. \stoptext What’s Next =========== * A harmonious-looking companion math font. * A harmonious-looking companion math font that uses glyphs from Adobe Serif 4 when available. Thanks, Vincent
