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.

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

\autoinsertedspace fails
by Rik Kabel 06 Jan '23

06 Jan '23

Happy New Year all! Following up on the problem with \autoinsertnextspace (https://mailman.ntg.nl/pipermail/ntg-context/2022/107111.html) and the new \autoinsertedspace that came from that report, I see that there is still a problem, or perhaps a problem again after it was previously repaired. The following code, run under the latest (and recent previous) version, produces an incorrect result, with no space inserted where expected in many cases. As the first examples after \starttext show, the problem appears to be with \autoinsertedspace, but perhaps I am using it incorrectly in the macro as well. \starttexdefinition unexpanded BD \dodoublegroupempty \doBD \stoptexdefinition \starttexdefinition doBD #1#2 \removeunwantedspaces\ % insert a space ( \ifsecondargument #1|–|#2 \else\iffirstargument #1– \else {\red I NEED A DATE OR DATES!} \fi\fi ) \autoinsertedspace \stoptexdefinition \tt \starttext This\autoinsertedspace fails unexpectedly with autoinsertedspace.\par This\autoinsertedspace \emph{fails unexpectedly} with autoinsertedspace.\par This\autoinsertnextspace works with autoinsertnextspace.\par This\autoinsertnextspace \emph{fails} as expected with autoinsertnextspace.\par Saussure\BD{1857}{1913} works.\par Saussure \BD{1857}{1913} \emph{works}.\par Saussure \BD{1857}{1913}.

Ajami script

I just read this: https://www.bu.edu/articles/2022/fallou-ngom-discovers-ajami-african-writin… And now I’d like to know if ConTeXt is capable of typesetting this variant of Arabic. (Just out of curiosity, I can’t read any Arabic and don’t know any African language.) Hraban

numbering questions
by Henning Hraban Ramm 01 Jan '23

01 Jan '23

A happy new year to everyone! I’m playing with some examples of section numbering. * Is there a setup to influence the order of number segments? I.e. can I have “section.chapter.part“ instead of “part.chapter.section”? * How can I format the segments, e.g. to get two or three digits each (leading zeros)? * I can force a section number with “ownnumber”, but the next one is back in the previous scheme. Itemize has “start”. How can I start section chapter numbering at 3 (or -1 or whatever; I know I can start at 0 with “zero”) and let ConTeXt continue from there? My example tries to (ab)use the section numbering for a date (e.g. for a diary): ----- \definestructureconversionset[default][n,n,month,n][n] \definestructureseparatorset [default][-,-,-,-] \definehead[Year][chapter] \definehead[Month][section] \definehead[Day][subsection] \define[2]\TitleCmd{#1} % number only \setuphead[Year,Month,Day][number=yes,page=no,command=\TitleCmd] \setuphead[Year][page=yes] %\setuphead[Month][] \setuphead[Day][style={\ss\bf}] \def\Dummycontent{ \dorecurse{12}{ \startMonth New Month. \dorecurse{5}{ \startDay Another day. \stopDay } \stopMonth }} \starttext \startYear[ownnumber=2023,title=This] A new year begins. \Dummycontent \stopYear \startYear Next year. \Dummycontent \stopYear \stoptext ----- Hraban

Adding support for German language to the Words conversion
by Marcus Christopher Ludl 31 Dec '22

31 Dec '22

Hello all, this is my first contribution to this mailing list. 😄 Recently, when I posted a question on StackExchange.com regarding adding support for another language (German) to the "Words" conversion in ConTeXt (see here: https://tex.stackexchange.com/questions/657534/how-to-add-support-for-anoth…) @mickep suggested that I post the patched file (core-con.lua) to the mailing list, once I have it finished, so that it can be added for all to use. So, now that I'm confident my code works well, I would like to do just that. 😄 How should I proceed? Should I just send the file including my new code as an attachement to the mailing list? Or would it be preferrable to paste only the new parts of the code inline into an e-mail? Is that even the correct mailing list or would it be better to send this to dev-context(a)ntg.nl? Best, Marcus

language identifier for all languages
by Pablo Rodriguez 30 Dec '22

30 Dec '22

Hi Hans, as already mentioned in a previous thread (https://mailman.ntg.nl/pipermail/ntg-context/2022/106713.html) I think it might be useful to have an identifier for any language, such as in: \setuphyphenation[method=traditional] \registerhyphenationexception[*][macOS] \registerhyphenationexception[any][macOS] \registerhyphenationexception[it][macOS] \startbuffer \currentlanguage: \hyphenatedword{macOS} \stopbuffer \starttext \startTEXpage[offset=1em] \getbuffer \language[it]\getbuffer \stopTEXpage \stoptext I think this is better than having other commands to add hyphenation exceptions for all languages. I wonder whether Steffen would be fine with this addition. Many thanks for your help, Pablo

New c-o-w: The XMas gift for ConTeXt users
by Zdeněk Svoboda 28 Dec '22

28 Dec '22

Hello ConTeXt community! I'm Zdeněk Svoboda, a master degree student at Mendel university in Brno. I've been using ConTeXt for a while now and have always been impressed by its capabilities and the helpfulness of this community. For my thesis project with Tomáš Hála as the supervisor, I've developed an online application for working with ConTeXt. The main goal was to create an application capable of compiling ConTeXt source right from the browser but I thought that it's not enough and added a few features or tools on top of that. Functions of the application include: - User accounts to save files and access them from other computers. - Editor with syntax highlighting and autocompletion for ConTeXt command. - Generating PDF document and previewing it directly from the browser. - Layout designer to customize the layout of their documents with a variety of options and mouse resizability of each layout element. - Table designer for creating and customize tables with alignment and border settings, colors, merging and splitting cells eg. - Lists designer with a simple interface to customize lists. - Help function for ConTeXt commands (hidden under the "?" button) Developing this application was a great learning experience for me, and I faced a number of technical challenges along the way. For example, having to dig through the XML document to extract all the information needed for the "?" help function. I'm excited to share my project with the ConTeXt community and hope that it will be a useful resource for someone. If you're interested in trying it out, you can find it at https://www.context-on-web.eu/. I'd love to hear any feedback or suggestions you have. If you find a bug or encounter an error while using the application, please let me know (and cc: thala(a)mendelu.cz) the steps you took that caused it. Known bugs: - Generated code from table designer needs better formatting - Duplicated color definitions in table designer - Layout designer -- numbers are not rounded Best regards, Zdeněk Svoboda

MWE: \starttext $a^2′$ $a′^2$ $\mathord{a′}^2$ $a^*^2$ \stoptext Should the \mathord{} be necessary to get the desired result? (I would expect the second line to work, just like $a^*^2$.) Alan
