Fwd: Lucida-1.901 (2023-01-21) available
by Henning Hraban Ramm 27 Jan '23

27 Jan '23

https://tug.org/pipermail/lucida/2023-January/000921.html A new version (1.901) of the Lucida OpenType fonts from TUG is available. As with previous updates, there's no additional charge if you've already purchased licenses; you can use the same download information sent to you at the time of purchase to get the new fonts. (If you've lost the download info, you can email us at lucida-admin at tug.org.) I will append the changes for this release. The same information is also online at https://tug.org/store/lucida/NEWS.txt. To summarize, the most significant changes have been to the math fonts, especially the regular-weight LucidaBrightMathOT. Many of these changes were discussed in greater detail in the recent article about Lucida math by Hans Hagen and Mikael Sundqvist: https://tug.org/TUGboat/tb43-3/tb135hagen-lucida.pdf The four Lucida Sans fonts and the three specialized fonts (Blackletter, Calligraphy, Handwriting) are not changed at all from the last release (not even version numbers or dates). All other fonts were changed. On behalf of TUG, I thank Hans, Mikael, and Michael Sharpe, who among them did essentially all of the technical font editing for this release. And we must thank Chuck Bigelow and Kris Holmes (they approved this release, as always), without whom nothing could be done. Bug reports and character/feature requests are welcome (email to this list is best), though, as usual, we cannot promise any particular timeline for the next release. Happy typesetting, Karl [Berry]

protected macro vs protected luacall
by Henri Menke 27 Jan '23

27 Jan '23

Dear list, I have noticed a somewhat strange difference between protected macros and protected luacalls, namely that the latter cannot be expanded by \the. In the example below I define a Lua function that prints \numexpr 17\relax to the token stream and I call it once from a protected TeX macro wrapping \directlua and once from a protected luacall registered with token.set_lua. \directlua{ userdata = userdata or {} function userdata.test() tex.print("\string\\numexpr 17\string\\relax") end } \tt \protected\def\test{\directlua{userdata.test()}} \meaning\test\par \edef\x{\test}\meaning\x\par \the\test \directlua{ local t = lua.get_functions_table() t[\string#t + 1] = userdata.test token.set_lua("test", userdata.test, \string#t, "protected") } \meaning\test\par \edef\x{\test}\meaning\x\par \the\test \bye However, the second \the\test fails with the following error: ! You can't use `luacall 0' after \the. l.21 \the\test Is this asymmetry between luacalls and regular macros intended? Is there a workaround where I can have a luacall that doesn't expand inside of \edef but still expands after \the? Cheers, Henri

Printing mailing list labels
by Bruce Horrocks 26 Jan '23

26 Jan '23

If you've ever struggled with Word's or (worse) LibreOffice's mail merge features to print a mailing list onto sticky labels then this might be of interest. I've created some macros and an example file showing how to print address labels on Avery L7160 paper (which is 7 rows of 3 labels on A4) and uploaded them here. <https://context-address-labels.sourceforge.io/> Features: - full control over label content (can even differ from one label to the next if necessary) - easily use up a part-used sheet of labels to avoid waste - read address data from a CSV file - easily support different address formats for different international destinations - option to preview on plain paper - even label your labels in the page header so you remember why you printed them! No licence - the files are placed in the public domain. Feedback welcome. — Bruce Horrocks Hampshire, UK

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
