LMTX: Command handling, Interface between TeX and Lua
by Gerion Entrup 14 Dec '23

14 Dec '23

Hi, I'd like to understand more of the inner workings of LMTX. When I understand it right, most of the code is now processed in Lua but I was not able to find it. For example, I tried to find out how setupitemgroup is handled (just as an example of a more complex command). The wiki has a (kind of) autogenerated description: https://wiki.contextgarden.net/Command/setupitemgroup I found the data for this (at least this is my guess) here: tex/texmf-context/tex/context/interface/mkiv/i-itemgroup.xml Are these xml files created by hand or somehow generated? Now, when I use `\setupitemgroup[itemize:1][symbol=3,itemalign=middle]`: How are the arguments handled and is this a generic process or specific to each command? Is there a simple way to define a new command/environment and handle the keyword arguments in Lua? For example defining a frontend command like this: \startsomething[firstword={Some},secondword={Text}] Body \stopsomething which I can handle in some lua code like this: function something(firstword, secondword, body) tex.print(firstword) tex.print(secondword) tex.print(body) end Are there any resources beside the context code itself where I can learn that?

Hi, Is this a bug or not ? The key to coloring the background of the text seems to no longer work.

Score sums and references
by Jairo A. del Rio 14 Dec '23

14 Dec '23

Hi, dear list. Is there a proper "ConTeXt way" to do the following? \integerdef\lmao=0 \starttext Sum: \in[trick] % 10 from the result below +1\advance\lmao\plusone +2\advance\lmao\plustwo +3\advance\lmao\plusthree +4\advance\lmao\plusfour \normalexpanded{\reference[trick]{\the\lmao}} % 10 printed above \stoptext I want the result of a sum (either via Lua or TeX) to be printed before summands in text, but without the mess of reference options such as interaction, etc. Thank you in advance and sorry for any inconvenience. Regards, Jairo

regular online meet-up
by Henning Hraban Ramm 13 Dec '23

13 Dec '23

Hi folks, I completely forgot to invite you to the last online meet-up of the year, this Wednesday, December 13th, 19:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Looking forward to seeing you, Hraban (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...

margin bigger than backspace pushes it outside the edge
by Jigé 10 Dec '23

10 Dec '23

Hi all, I've been struggling with basic page layout. The left margin extends outside the left edge of the page. Example (from the wiki): \setuppapersize[A4][A4] % this is the default and may be omitted \setuplayout[backspace=20mm, width=110mm, topspace=20mm, header=0mm, footer=0mm, height=250mm] \starttext \showlayout \stoptext Another example: \setuppapersize[A5][A4] \setuplayout[location=middle] \usemodule[ipsum] \starttext \showframe \ipsum \stoptext Thanks, Jean-Guillaume

Complete working minimal examples are preferred over code snippets. To avoid single lines with different spacing you can either increase the line spacing for all lines with \setupinterlinespace or you use a different fraction command which uses smaller numbers or creates inline fractions. \starttext \startlines \type{\frac{1}{3}}: \m{\frac{1}{3}} \type{\xfrac{1}{3}}: \m{\xfrac{1}{3}} \type{\xxfrac{1}{3}}: \m{\xxfrac{1}{3}} \type{\tfrac{1}{3}}: \m{\tfrac{1}{3}} \type{\sfrac{1}{3}}: \m{\sfrac{1}{3}} \type{\frac{1}{3}}: \m{\frac{1}{3}} \type{\dfrac{1}{3}}: \m{\dfrac{1}{3}} \type{\cfrac{1}{3}}: \m{\cfrac{1}{3}} \type{\vfrac{1}{3}}: \m{\vfrac{1}{3}} \type{\hfrac{1}{3}}: \m{\hfrac{1}{3}} \stoplines \stoptext Wolfgang

Dear List, In the MWE below, the left and right arguments are not applied in the last chapter. How can this be fixed? \starttext \startlinenumbering[left={[},right={]}] \dorecurse{5}{% \startchapter[title={Knuth}] \samplefile{knuth} \stopchapter } \stoplinenumbering \stoptext Kind regards Marcus Vinicius -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.
