pgfplots module wrecks in latest
by Gavin 25 Jan '23

25 Jan '23

Hi List, The TikZ related module “pgfplots” is causing a fatal error in the latest ConTeXt. Here is a MWE: \usemodule[tikz] \usemodule[pgfplots] % PGFPlots module for graphs \starttext \starttikzpicture \draw (0, 0) circle (3cm); \stoptikzpicture \stoptext Without loading the pgfplots module, this draws a circle. With the \usemodule[pgfplots] line, this has the error below before doing anything. I don’t know when this started happening, because I don’t use pgfplots often, but it was probably in the last couple months. Thanks for all the great updates! Gavin tex error > tex error on line 521 in file pgfplots.code.tex: Use of \pgfplots@command@to@string@@ doesn't match its definition <inserted text> m acro:colormap <argument> \pgfplots@colormap@catcodemagic <macro> \pgfplots@command@to@string #1#2->\expandafter \pgfplots@command@to@string@@ \meaning #1 \pgfplots@EOI {#2} <line 6.521> \pgfplots@command@to@string\pgfplots@colormap@catcodemagic\pgfplots@colormap@catcodemagic <empty file> If you say, e.g., '\def\a1{...}', then you must always put '1' after '\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it.

ConTeXt features in pandoc 3
by Albert Krewinkel 24 Jan '23

24 Jan '23

Hello, a new version of pandoc, the universal document converter, was released two days ago; pandoc 3 comes with new ConTeXt-related features on which we've spend a good bit of time: - *Syntax highlighting*: Pandoc makes use of the syntax definitions and styles created by the KDE project to highlight source code. This already worked with HTML, LaTeX, and formats like docx, and is now also supported for ConTeXt. - *Inline code*: older versions of pandoc had some weird behavior wrt inline code in ConTeXt, switching between `\type` and `\mono`, which made it difficult to customize the output. This has been fixed. - *Tagging-focused output*: Calling pandoc with `--to=context+tagging` creates markup that is geared towards the creation of tagged PDFs. This can be combined with `-V pdfa=3a` to produce accessible PDFs from various input sources. - *Unlisted/unnumbered headings*: Headings with class "unnumbered" are not numbered; those with class "unlisted" get omitted from the ToC. - *Figures*: We have improved support for figures considerably, and now also support subfigures. This is currently most noticeable when converting from HTML to ConTeXt. Downloads and full changelog: https://github.com/jgm/pandoc/releases/tag/3.0 I'm grateful for any and all feedback, including tips on how to improve pandoc further. Cheers, Albert -- Albert Krewinkel GPG: 8eed e3e2 e8c5 6f18 81fe e836 388d c0b2 1f63 1124

KeenType 1.0.0 (NTS fork)
by Thangalin 23 Jan '23

23 Jan '23

Hi folks, I forked the New Typesetting System (NTS) as KeenType. KeenType is a 100% pure Java library/app that can generate SVG diagrams from plain TeX documents. Here's a list of the changes (and sample output): https://github.com/DaveJarvis/KeenType/releases/tag/1.0.0 Here's how typesetting appears in KeenWrite: https://raw.githubusercontent.com/DaveJarvis/KeenType/main/docs/images/keen… Special thanks to Hans and Taco who, no doubt, played important roles in bringing the original NTS to life. My sincere gratitude to any NTS developers who may be reading. For further details, see: https://github.com/DaveJarvis/KeenType/ Cheers!

font features in the wiki
by Pablo Rodriguez 22 Jan '23

22 Jan '23

Dear list, since Hans has asked me for an addition to the wiki, I was thinking of adding a complete explanation of font features. I must admit that https://wiki.contextgarden.net/Featuresets wouldn’t be the best way that I would choose to explain this. Of course, I don’t want to impose my view on this topic. I wonder whether it would make sense that I start a new article on font features and when finished, see the way to merge the contents from the featureset. I’m especially asking Idris, Hraban and MHB. Of course, I might be wrong and I’m happy to be corrected about my proposal on font features in the wiki. Many thanks for your help, Pablo

rewrite for Greek in the wiki
by Pablo Rodriguez 22 Jan '23

22 Jan '23

Dear list, just in case it might help, I’ve rewritten the Greek entry in the wiki: https://wiki.contextgarden.net/Greek Although nobody seemed to have mentioned them (afaIk), there are two issues: 1. Hyphenation patterns are different for ancient, monotonic and modern polytonic Greek. Greek ortography was polytonic before 1982. ConTeXt includes patterns for ancient and monotonic Greek, but none for modern polytonic Greek (http://mirror.ctan.org/language/hyph-utf8/tex/generic/hyph-utf8/patterns/te…). Ironically, modern polytonic Greek patterns would be required to typeset both the act and the decree that introduced the monotonic ortography. 2. Greek doesn’t seem to have language-dependent commands (such as \currentdate). In both cases, Hans will reply that nobody asked for any of them. Of course, I totally agree. AfaIk, nobody asked for these features. Just in case it might help, Pablo

Change in \vec behavior
by Jean-Philippe Rey 22 Jan '23

22 Jan '23

Hello, As I usually do at the end of each year, I upgraded my ConTeXt installation. I noticed a change in \vec behavior which doesn't extend the arrow anymore. Here is my example: \starttext Engine: \texenginename\ \texengineversion \ConTeXt: \contextversionnumber \type{$\vec{AB}$} : $\vec{AB}$ \stoptext The result with the latest ConTeXt version: and with the version from a year ago: I am aware that I could use \overrightarrow, but I prefer the shape and position of the \vec arrow, especially with single letters. What is the rationale for the change in \vec? Is there a way to get the previous behavior back? Thanks, -- Jean-Philippe Rey jean-philippe.rey(a)centralesupelec.fr 91192 Gif-sur-Yvette Cedex - France Empreinte PGP : 807A 5B2C 69E4 D4B5 783A 428A 1B5E E83E 261B BF51

variable font not working
by Pablo Rodriguez 22 Jan '23

22 Jan '23

Dear list, using current latest (from 2023.01.15 14:04), the just released version of Source Serif 4 Variable (https://github.com/adobe-fonts/source-serif/releases/latest) and the following sample: \usemodule[fonts-variable] \starttext \showfontvariations[font=file:SourceSerif4Variable-Roman.otf] \stoptext ConTeX outputs no text with that font. Could anyone confirm the issue? Many thanks for your help, Pablo

Why won't custom indexes work when the value comes from \getvalue?
by Joel 21 Jan '23

21 Jan '23

I setup a custom index like this (see minimum example code below): The problem is, when I try to create an index entry, using \setcoreidea, but place \getvalue inside, it won't render, ex.: \setcoreidea{\getvalue{secret1}} As you can see in this sample code, \setcoreidea will work fine, but when \getvalue{} is placed inside, it can't find the value. Any suggestions? --Joel \defineregister[coreidea][compress=yes]\setupregister[coreidea][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] \define[1]\setcoreidea{% \coreidea{#1}% } \setvalue{secret1}{this won't work} \starttext % \setcoreidea{this works} \input knuth \input knuth \input knuth \input knuth \setcoreidea{\getvalue{secret1}} \startchapter[title=Core Ideas] \placecoreidea \stopchapter \stoptext
