problem with symbols in index
by Henning Hraban Ramm 18 Jul '23

18 Jul '23

I hunted for two days after an index error in my book: """ structure > sectioning > chapter @ level 2 : 0.1 -> Sachregister tex error > tex error on line 95 in file ./prd_test.tex: The file ended when scanning an argument. {\startregisterentries {1}\startregisterentry {0}\registerentry {index}{}{21}{}{[[special cmd: lua call]]}\startregisterpages \registeronepage {index}{}{21}{2}{[[special cmd: lua call]]}\stopregisterpages \stopregisterentry \stopregisterentries \stopregistersection \stopregisteroutput \relax \stopmixedcolumns \else \strc_registers_place_indeed {index}\fi \endgroup \fi \stopchapter \par \par \par \par \par \stopproduct """ It boiled down to \index{\%} that used to work but doesn’t any more in current LMTX. Also, "context --purge" doesn’t delete the tuc file (don’t know if that changed), so the wrong entry stuck in there, and my code changes didn’t affect it. MWE: \starttext %\index{\%} \index[ ]{\backslash} \index[ ]{\percent} \index[ ]{\tex{}} \index[ ]{\tex{}\tex{}} \index[ ]{\tex{\%}} \page \completeindex \stoptext For my command index, \index[something]{\tex{something}} works, but is there a better way to put \\ in there than \index[ ]{\tex{}\tex{}} ?

If Hans didn’t add it recently, there‘s no automatical downsampling in ConTeXt (yet), that’s why I want to do this; the resolution parameter is apparently never used. Hraban

access image properties in Lua
by Henning Hraban Ramm 17 Jul '23

17 Jul '23

What’s the current approved way to get image properties within a Lua function? very old: local pic = figures.getinfo(figures.current().status.fullname) used to work in 2019: local pic = img.scan{filename = figures.current().status.fullname} if I understand this right, "img" isn’t valid anymore: """ token call, execute: grph-imagelib.lua:37: attempt to index a nil value (global 'img') """ I’d like to know the pixel size and if possible also the scaled target size of an image; either the "current" one or by name.

\hidewidth disappeared
by Hans van der Meer 16 Jul '23

16 Jul '23

What happened to \hidewidth? It looks as if it disappeared. See the accompanying MWE. However, searching the ConTeXt source I find it used in enco-ini.mkiv, defined in syst-ini.mkiv, but commented out in syst-ini.mkxl. Why is that? It seems a harmless definition, and its body is even used twice in enco-ini.mkxl. I dare say, with all due respect, it is not pleasant (and a waste of time) to find working code suddenly broken because of leftout macro's. And I feel lucky to not having used \ialign, because something similar happened to it. yours sincerely dr. Hans van der Meer

Text item groups
by Jairo A. del Rio 16 Jul '23

16 Jul '23

Hi, list! I want to know how to make numbers in text item groups run along with text (for instance, wrt indentation) regardless of their position in text. In the following example: \setupindenting[yes,medium] \starttext \startitemize[a,text][textdistance=none] \startitem \input{jojomayer}\stopitem \startitem \input{jojomayer}\stopitem \startitem \input{jojomayer}\stopitem \stopitemize \stoptext Indentation is ignored altogether. Thank you in advance Regards, Jairo

depth of framed
by Hans van der Meer 16 Jul '23

16 Jul '23

I cannot get rid of some depth in framed. Used various combinations of the depth and backgrounddepth setting, nothing helps. What am I doing wrong? Or is something in \framed not working in the way I expected? See the accompanying MWE. yours sincerely dr. Hans van der Meer

digitally sign fields with MuPDF-GL
by Pablo Rodriguez 13 Jul '23

13 Jul '23

Dear list, having the following sample code: \setuppapersize[A4, landscape] \setuplayout[page] \setupinteraction[state=start] \starttext \setupfield[sl][horizontal] [frame=off, width=\textwidth, height=\textheight] \definefield[x][signature][sl] \field[x] I also attach a sample certificate with password ABCabc. The binaries for Windows provided by Artifex do not provide SSL support. I’m on Linux myself, and something like MSYS2 provides binaries with support for Linux (https://packages.msys2.org/base/mingw-w64-mupdf) I wonder whether Homebrew provides mupdf-gl (I cannot say from https://formulae.brew.sh/formula/mupdf) If I try to sign the output PDF with the previous password, using mupdf-gl or "mutool sign" (version 1.2.2), the signature annotation is only viewed by MuPDF, MuPDF-GL and SumatraPDF. On Linux, neither Evince or xpdf can display the signature annotation. On Windows, Acrobat Reader DC doesn’t display the signature annotation, nor it shows any info about the document being signed (BTW, I used another certificate for this). If I open the unsigned document with Acrobat Reader DC and save it, then mupdf-gl can sign the saved document that Acrobat can handle (both annotation and signature info) and Evince and xpdf can display the signature. I guess what might be causing this issue and I’m investigating it. But it would really help, if someone can confirm the issue with MuPDF-GL (or "mutool sign") and Acrobat (Reader or not). Many thanks for your help, Pablo

regular online meet-up
by Henning Hraban Ramm 12 Jul '23

12 Jul '23

You’re invited to join on Wednesday, July 12th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! This is directly before the TUG/DANTE conference; you can get a preview of my talk for Bonn ;) Next meeting will be on August 9th. And this is just before the Chaos Communication Camp, where I’ll give ConTeXt talks/workshops, too. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban
