\ifnum with two \recurselevel
by Pablo Rodriguez 09 May '25

09 May '25

Dear list, I have the following sample code: \starttext \startTEXpage[offset=1dk] \dostepwiserecurse{2}{6}{1}{\edef\AbC{\recurselevel}% \dostepwiserecurse{2}{7}{1}{%\AbC.\recurselevel\ /\ \ifnum\AbC < \recurselevel% \AbC:\recurselevel\ \|\| \fi} \\} \stopTEXpage \stoptext I would like to only get the numbers in the form first:second loops if and only if the value of the first loop is less than the value from the second loop. I think this should be simple, but I don’t get it with any of these conditionals: \ifnum\AbC < \recurselevel \ifnum\recurselevel > \AbC Sorry for the stupid question, but what I am missing here? Many thanks for your help, Pablo

modernizing
by Hans Hagen 08 May '25

08 May '25

Hi, At last week bachotex we (Tove, Mikael, Willi, Hans) cinducted the first in a series of experiments and presentations dealing with accessibility. After all, why bother more about pdf than of the tool that makes it. - we tested if qr codes were easier on users than tex error messages (experiment conducted with high end wooden ear-tags with qr codes made by Willi, who else) because after all humans are good in pattern recognition - we (read: Tove, well known from the "ts" unit) tested to what extend colors could be recognized (after all in Sweden PDF documents have to obey very strict rules wrt color); we will report later on this promissing "flagged pdf" (with color light bulbs triggered by pdf) experiment in an article - as side track (okay: logical follow up) we checked how users react on more vivid visual feedback (this is already supported but the manual was on purpose not yet added to the distribution); we will follow up on this at the context meeting You can do part of this experiment by adding this to the top of your file: % signal=qr (There's also a command line option plus a related script. The next upload will have the preliminary "signals.pdf" manual, just in case you have the needed equipment.) In that case an error will pop up a qr code. The idea is that after while you (or your mobile phone) will recognize these messages easier than parsing a log. It also fits more in todays paradigms. We might eplore easy installations with qr codes because after all that's how things are done these days. So, thanks to Tove, we ended up in modern times.

curl missing from Docker image -> install-modules does not work

Hello, installing modules into the docker image is not possible since the curl command is not part of the image.

06 May '25

Dear list members, Registration for the 19th ConTeXt Meeting https://meeting.contextgarden.net/2025/ is now open. This year we are hosted in Ośrodek Wypoczynkowy KREFTA in Chmielno near Gdańsk, Poland. https://krefta.pl/ The accommodation is a camp site with little huts and a main house, comparable to that in Bachotek; Ryszard Kubiak is the local organizer. The theme for this meeting is What if ...? but as you know we have never been that strict about a particular theme, so feel free to suggest other topics to talk about. Dates and deadlines • June 30, 2025, deadline for early bird payment • August 1, 2025, registration closes, ask for options after this deadline • August 23–29, 2025, 19th ConTeXt Meeting Never been to the ConTeXt Meeting? Don't worry, the group of regular participants is open and friendly, and you don't know what you are missing, unless you come at least once. Different discount options https://meeting.contextgarden.net/2025/fee.shtml are available. We hope to see you in August! Ryszard, Hans, and Taco -- Taco Hoekwater cg-secretary(a)contextgarden.net

talmudifier
by Henning Hraban Ramm 04 May '25

04 May '25

I found this interesting: https://crates.io/crates/talmudifier (it uses a Rust version of XeTeX) Is such a layout a challenge for the new columns engine? The description of the algorithm reads like ConTeXt should be able to do it better/faster. Hraban

When uncommenting the first line the header disappears ( ConTeXt ver: 2025.04.28 14:29 LMTX). Is this a bug? Steffen %\setupbackend[export=yes] \starttext \startsection [title={\ConTeXt\ is fun}] \stopsection \stoptext

TDM Reservation Protocol (TDMRep)
by Steffen Wolfrum 01 May '25

01 May '25

Hi, we just saw the Accessibility Directive, now there is another demand: the TDM protocol (concerning the reuse of protected works for AI training purposes). Is it possible to implement these TDM Metadata when producing PDF files with ConTeXt? This technique provides a way to embed the rightsholder's choice into a PDF file. (See «§6.6 TDM Metadata in PDF files»: https://www.w3.org/community/reports/tdmrep/CG-FINAL-tdmrep-20240510/#sec-p…) Steffen

Hello, I think the following used to place the footnote rule on the right side (as in rule=right). Now it doesn't. --------- \setupfootnotes[rule=paragraph] \starttext \setupalign[r2l] hello\footnote{foot} \stoptext --------- Am I doing something wrong? Thanks, Mohammad

cannot find fonts in a manual install; what did I miss
by damien＠thiriet.web4me.fr 30 Apr '25

30 Apr '25

Hello! Since OpenBSD has upgraded to 7.7, I performed a manual installation of LMTX standalone after upgrading to my new OS version. What I did: download cont-lmt.zip into /usr/local/context/tex/texmf-context/ mv /home/dthiriet/cont-lmt.zip . unzip cont-lmt.zip cd source/luametatex/ ./build.sh (ou si ça ne marche pas pour des raisons d’autorisation: sh build.sh) cp build/native/luametatex tex/texmf-openbsd-amd64/bin/ depuis $HOME mtxrun --generate mtxrun --script fonts --reload Everything compiles, but the fonts are not found: fonts > defining > font with asked name 'lmsans10-regular' is not found using lookup 'file' fonts > defining > unable to define 'lmsans10-regular' as 'modern-12pt-ss-tf-' fonts > defining > forced type 'otf' of 'latinmodern-math' not found fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mr-' fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mb-' fonts > 'fallback modern ss 12pt' is loaded When I search my texmf-context file, I cannot find these otf files, so the problem isn't that I put them in the wrong place. I compared with my previous context install, and I can see the difference is that in the former my tree looked like this /usr/local/context | |-- texmf-context/ |-- texmf-openbsd-amd64/ |-- texmf This texmf/ folder, which contains fonts/ (with lmodern otf files and so on) and web2c misses in my current tree. But the context-readme.txt AFAIU does not say anything about a texmf/ folder in the tree. What did I miss? Should I have downloaded another zip from pragma pages? Thanks, Damien
