Phew, CGJ 2025, i.e. the Context Group Journal, AKA members magazine, AKA proceedings of last year’s meeting in Chmielno, Poland, is off to the printshop.
It’s a thin issue this time, only 40 instead of ~100 pages.

It has a meeting report, a description of the development of the “signal” (AKA watch), an article about typesetting directory trees and a long one about making Perlin Noise in MetaPost.

Members only, public in a few months at https://articles.contextgarden.net/

If you’d like to attend the upcoming ConTeXt meeting, please register now!
Registration closes on sunday.

“If you can’t implement something in Lua, then you're not trying hard
enough ;).”

“… the ConTeXt Lua interfaces are really nice, and OpTeX’s are pretty
good too, but the other formats provide almost no interfaces which makes
using Lua quite annoying.”

(Max Chernoff)

TIL: Footnotes within MetaPost textext (at least with the nodes modules) get wrongly numbered due to multiple passes and uncaught boundary conditions.
Using footnotes in graphics wasn’t expected …
A fix will need time and opportunity.

Since we just heard about people BUYING QR codes… 🤦

– QR codes can contain anything you want, but usually only a URL.
– There are MANY free tools to create them.

ConTeXt has an integrated function:
\qrcode[text={https:/ /wiki.contextgarden.net},color=orange,width=5cm]
in Lua, it’s
figures.qrcode{"https:/ /fosstodon.org/@context","orange",tex.sp("5cm")}

For those who can read QR: The parameter "--signal=qr" creates error messages as QR codes.

Have fun!

Registration for the upcoming ConTeXt meeting closes on August 9.
There are still a few places left.

https://meeting.contextgarden.net/

This time, it takes place August 24-29 in Maibach, a village between Frankfurt/Main and Gießen (middle of Germany).

For everyone interested in our “TeX with cow powers”, this is a great opportunity to learn to know the developers and users, to discuss, learn, solve problems and just have some TeXie fun. We are a friendly and open-minded bunch…

#TeXConTeXt

There's a ConTeXt LMTX update, focussing on 3D graphics (MetaPost, STL etc.).

Full announcement: https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/JLSM5LODAVMFCSPFMC7T32EPUYHC3MGV/

Our events are now also available on Mobilizon:

You don’t need to be a Hans Hagen fan to use ConTeXt, but it helps. 😉

So we need to mention: Hans declared defeat in a discussion about LMTX:
No, you can’t run plain TeX with it out of the box, since it lacks kpsewhich and mktexlsr. (ConTeXt has better mechanisms for finding files.)

With ConTeXt in TeX live, you can run

mtxrun --script plain --make

to generate the plain format for LuaMetaTeX.

🤫 Insider information: there’s some unique member benefit coming up.

Friends of ConTeXt should become members of context group now – it’s only 40 € per year, 20 € for students, while the member discount for ConTeXt meetings is already 50 €, additionally you’ll get the context journal (AKA proceedings).

#TeXConTeXt

TUG conference in Calgary, Canada, is starting today:
https://tug.org/tug2026/

There’s a live stream on YouTube.

The program doesn’t seem to contain anything about ConTeXt or MetaPost. Well, we’re apparently somewhat eurocentric… (But Pavneet Arora was president of context group, so his talk on documentation in engineering will probably mention ConTeXt.)

#TUG #TeXLaTeΧ

🤫 fresh from the LuaMetaFun kitchen:

Still undocumented function lmt_stipple allows, well, stippled fills. And with some Voronoi magic, you can create eerie spider web graphics. 🕸️ 🎃 😉

#TexConTeXt #MetaPost

You’re invited to our regular online meet-up,
Wednesday, July 15th, 19:30 CEST (UTC+2)
at https://lecture.senfcall.de/hen-rbr-rku-oke

That should have been today, but I forgot to invite…

This is usually a Q&A with the developers and chat about current projects.
ConTeXt users of all levels are welcome!

#TeXConTeXt

There were two ConTeXt LMTX updates in the last few days. As far as we know they contain only bugfixes as results from discussions on the mailinglist.

#TeXConTeXt #LMTX

According to https://github.com/mozilla/pdf.js/pull/21247, digital
signature verification was merged in PDF.js

Releases tend to be and the end of
the month, so this commit will be included in the release of the end of
July.

Which Firefox version may include the feature is still unknown.
According to https://whattrainisitnow.com/calendar/, although version
154 wouldn’t be completely impossible, probably version 155 (due to
09.15.2026) would be a safer bet.

There is now also a Serbian translation by Ivan Pešić of “A not so short introduction to ConTeXt – community edition” (ANSS-CE):
