images with alt text
by Steffen Wolfrum 06 Feb '25

06 Feb '25

Hi, as publishing houses (at least in Germany) are forced to provide «alt text» with their PDF-publications (from June 2025 on), I need to know how «images with alternate text» (https://en.wikipedia.org/wiki/Alt_attribute) are typeset with ConTeXt LMTX. In HTML it looks like this: <img src="example.jpg" alt="Example text"> What is the equivalent in ConTeXt LMTX? Yours, Steffen

max function in spreadsheettable
by juh+ntg-context＠mailbox.org 14 Nov '24

14 Nov '24

Dear all, I have a cell that calculates a value that may not be a negative value. If it is a negatiive value the cell should show zero. \startcell[style=normal] @ "0.2f EUR" $pauschale.eintag$ - ((D[row] * (0.2 * $pauschale.vororttag$)) + (E[row] * (0.4 * $pauschale.vororttag$)) + (F[row] * (0.4 * $pauschale.vororttag$))) \stopcell The $-variables will get resolved by Pandoc before ConTeXt comes into play. As far as I understood the handdbook spreadsheets-mkiv.pdf it is possible to define lua functions inside a cell. Who would you implement a max function that sets the value to 0 if it is negative? TIA juh P.S. For German speakers: We try to implement a Reisekostenformular.

serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

penalties
by Thomas Meyer 05 Nov '24

Hi folks, following today's update, \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} \setpenalties\clubpenalties {2}{10000} \stopsetups \setuplayout[grid=yes, setups=mypenalties] doesn't work any longer, I think. Can anyone confirm this. There is another problem (page break in the paragraph) that I have yet to verify. Greetings Thomas

Seeking Advice on Electron Configuration Notation in ConTeXt
by Jorge Manuel 31 Oct '24

31 Oct '24

Hello everyone, I’m searching for an efficient way to represent electronic configurations in subshell and orbital notation within ConTeXt. I found similar examples discussed on StackExchange, which you can see here: Atomic electronic configuration with small boxes: https://tex.stackexchange.com/questions/372581/atomic-electronic-configurat… Box and arrow notation of writing electron configuration https://tex.stackexchange.com/questions/616989/box-and-arrow-notation-of-wr… Ideally, I’d like to use a package similar to atoms.sty for this purpose. Does anyone know of a straightforward approach to achieve this in ConTeXt? Thank you very much for any guidance or examples! Best regards, Jorge

using command line arguments
by Henning Hraban Ramm 28 Oct '24

28 Oct '24

Hi, I’m trying to use a command line argument in parameter names – color name in the example below, variable namespace in my actual project. I guess I need more expansion, but where? Or what’s the problem here? """ \setupbodyfont[plex,18pt] % set \OEM to the parameter name, fall back to "fiee" \expanded\define\OEM{\expanded\doifelsedocumentargument{OEM}{\expanded\getdocumentargument{OEM}}{fiee}} \definecolor[col:fiee][c=1] \definecolor[col:pragma][m=1,y=1] \definecolor[col:black][k=1] \starttext \color[col:\OEM]{Company: \OEM} \stoptext """ Hraban

Spacing issue in \digits with mode=3
by Kirill Davidov 26 Oct '24

26 Oct '24

Greetings, I have been making a table with \digits aligned cells and noticed that in mode 3 (thin mu skips as group separator, comma as decimal separator) a specification like {_X.=} causes the single digit number to be misaligned, it's like there's about 2mu worth of space just before the number. I don't have much of an idea as to what causes it. It doesn't seem to be an issue in mode 1, although it may be simply not as noticeable. This also affects \unit. MWE: \setdigitmode{3} \startdocument \showglyphs \enabletrackers[visualizers.glue] \startxtable[align=center] \startxtablehead \startxrow \startxcell Data \stopxcell \stopxrow \stopxtablehead \startxtablebody \startxrow \startxcell \digits{10.001==} \stopxcell \stopxrow \startxrow \startxcell \digits{_1.=====} % weird spacing issue here \stopxcell \stopxrow \startxrow \startxcell \digits{20.34909} \stopxcell \stopxrow \stopxtablebody \stopxtable \halign{% \hss\alignmark\hss\cr \digits{10.001==}\cr \digits{_1.=====}\cr % weird spacing issue here \digits{20.34909}\cr } \stopdocument Kirill
