Containerized ConTeXt
by Thangalin 14 Dec '22

14 Dec '22

Hi again, I've added the start of a podman container for invoking ConTeXt that may be of interest: https://github.com/DaveJarvis/keenwrite/tree/main/container The Containerfile sets up ConTeXt to work with my themes: https://github.com/DaveJarvis/keenwrite-themes The manage.sh shell script is a wrapper around the podman command to help build, save, and load the container, as well as connect and run commands. It's a work-in-progress. My goal is to simplify the setup and configuration of ConTeXt as well as make the instructions "cross platform" owing to containerization. >From there, I want to call out to the container from KeenWrite to typeset PDF documents using one of the themes. Further, I'd like to have KeenWrite download and install ConTeXt automatically using podman. I believe this will make it easier for people to generate high-quality PDFs from (R) Markdown documents because they'd only have to download KeenWrite, then ask KeenWrite to download/configure ConTeXt automatically, in a cross-platform fashion. Thoughts? Suggestions for improvement?

regular online meet-up
by Henning Hraban Ramm 12 Dec '22

12 Dec '22

You’re invited to join on Wednesday, November 9th, 15:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! Next meeting will be on December 14th. (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

Dear List! Sorry, but my pdf was too big. So I send a little picture. [cid:image001.jpg@01D90E45.CE727480] I would like to know, if there is a modus in ConTeXt like the same in LaTeX. I found this on page 108, Chapter 3 Math symbos LaTeX Compherensive list. Many thanks Uschi

Seems to be a bug with \definelayout
by peter.hopcroft＠icloud.com 10 Dec '22

10 Dec '22

I’ve rewritten my last email. The context below produces the pdf in the screenshot below. I expect the layout[short] to be applied to pages 2 and 3. It is. But there seem to be 2 bugs: 1 - Pages 4, 5 and 6 have the [short] layout. They should have the default layout. 2 - On pages 5 and 6, the text flows beyond the bottom of the frame. It should stop at the bottom of the frame. Why do I think these are bugs? If I change the page number in \definelayout[3][short] to \definelayout[4][short], then it behaves differently and as I expect: only pages 2 and 4 have the [short] layout and the text flows within the frames.

extra hyphen in underscore hyphenation
by Pablo Rodriguez 10 Dec '22

10 Dec '22

Dear list, I have the following sample: \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") \stopluacode \definehyphenationfeatures [underscore] [righthyphenchar="FE000] \sethyphenationfeatures[underscore]% \setuphyphenation[method=traditional]% \starttext \startTEXpage[offset=1em, width=4em] \hsize\zeropoint\tt \hyphenatedword{legibility-legible} \stopTEXpage \stoptext In current latest (and in many versions before), I get an extra hyphen in the next line after the hyphen, such as: ity- -leg As far as I can remember, I would say this used to work before (no extra hyphen was added in the next line. What am I missing here? Many thanks for your help, Pablo

two issues with variable fonts
by Pablo Rodriguez 09 Dec '22

09 Dec '22

Hi Hans, I have two issues with variable fonts (using current latest from yesterday): 1. Using the following sample: \usemodule[fonts-variable] \starttext \showfontvariations[font=file:grenze.ttf] \stoptext With the fonts from https://github.com/Omnibus-Type/Grenze/tree/master/fonts-/gx, I get the following error message: lua error: run callback [6]: ...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-emb.lmt:84: number (local 'n') has no integer representation stack traceback: ...base/mkxl/lpdf-emb.lmt:84: in upvalue 'tocardinal2' ...base/mkxl/lpdf-emb.lmt:771: in local 'writer' ...base/mkxl/lpdf-emb.lmt:2358: in field 'integer index' ...base/mkxl/lpdf-ini.lmt:828: in upvalue 'run' ...base/mkxl/lpdf-ini.lmt:859: in field 'finalizedocument' ...base/mkxl/lpdf-lmt.lmt:3413: in field '?' ...base/mkxl/luat-run.lmt:58: in function <...ext/tex/texmf-context/tex/context/base/mkxl/luat-run.lmt:56> <empty file> mtx-context | fatal error: return code: 1 This crashes LuaMetaTeX but not LuaTeX. 2. The other font is Recursive (https://github.com/arrowtype/recursive/tree/main/fonts/recursive_for_google…) \usemodule[fonts-variable] \starttext \showfontvariations[font=file:recursive.ttf] \stoptext There are some some instances (in pages 4 to 14) that don’t have the font (only Latin Modern Roman). Also in the last instances (at least, pages 19 to 25), kerning or interletter spacing clearly needs to be improved. Many thanks for your help, Pablo

\definelayout[pagenumber][layout] behaving strangely
by peter.hopcroft＠icloud.com 09 Dec '22

09 Dec '22

The pdf from the tex below looks wrong to me, screenshot attached. It’s always like this when the page number in the second \definelayout is 1 more than the page number in the first. For other pairs of numbers, it behaves like I expect: the short layout is only on those 2 pages. I’m using the LMTX I updated a few days ago. ConTeXt online’s pdf is the same. %====================================================== \showframe \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE] \setuplayout[backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=200mm, margindistance=10mm, leftmargin=40mm] \definelayout[short][backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=80mm, margindistance=10mm, leftmargin=40mm] \starttext \definelayout[2][short] \definelayout[3][short] \dorecurse{10}{\input{knuth} } \stoptext %====================================================== Also, https://wiki.contextgarden.net/Command/definelayout says: % different layout for first two pages \definelayout[1][wide] \definelayout[3][reset] This does not work for me.

Achieving different \cite styles
by Jethro Djan 09 Dec '22

09 Dec '22

Hello everyone I am interested in being able to cite in different ways. By analogy, I refer to the \texcite{}, \parencite{} and other options available with biblatex in LaTeX. How do I achieve something like \textcite{} in ConTeXt? Here is my MWE: \startbuffer[ref] @Article{wn:2017, author = {Who, Nobody and What, Everyone}, journal = {Good Journal}, title = {The Art of Being}, year = {2017}, } \stopbuffer \definebtxdataset[ref] \usebtxdataset[ref][ref.buffer] \setupbtx[ dataset=ref, ] \definebtxrendering [ref] [apa] [ dataset=ref, ] \usebtxdefinitions[apa] \starttext In \cite[wn:2017], they illustrated that it is impossible to not be them. \cite[wn:2017] said it was worth the discovery. \startsection[title={References}, number=no, incrementnumber=no] \placelistofpublications[ref][method=dataset] \stopsection \stoptext The first sentence is okay. In the second, I would like the parenthesis around the citation to come off because of the way I am citing it. Jethro
