Upgrade (and fresh installation) failing with lua error in supp-box.mkxl
by Pavneet Arora 12 Feb '25

12 Feb '25

This past weekend I attempted and update on my FreeBSD distribution, and it failed with the following error: >>> open source > level 1, order 56, name 'supp-box.mkxl' loading > ConTeXt Support Macros / Boxes lua error > lua error on line 43 in file supp-box.mkxl: token call, execute: ...ext/tex/texmf-context/tex/context/base/mkxl/node-ini.lmt:214: attempt to index a nil value (global 'mathematics') stack traceback: ...ext/tex/texmf-context/tex/context/base/mkxl/node-ini.lmt:214: in metamethod 'index' ...ext/tex/texmf-context/tex/context/base/mkxl/supp-box.lmt:37: in local 'code' ...ext/tex/texmf-context/tex/context/base/mkiv/util-lua.lua:97: in field 'loadedluacode' ...ext/tex/texmf-context/tex/context/base/mkiv/luat-env.lua:108: in field 'luafilechunk' ...ext/tex/texmf-context/tex/context/base/mkxl/luat-cod.lmt:82: in function 'lua.registercode' [ctxlua]:1: in main chunk <empty file> A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) <<< I subsequently tried a fresh installation with the same error message. I haven't seen mention of this elsewhere, and so am assuming that this might be a FreeBSD specific issue? advTHANKSance. -- Pavneet Arora m: +1 647-406-6843 Waroc Informatik e: pavneet_arora(a)waroc.com

[ drawing lines with metafun ]
by vm 12 Feb '25

12 Feb '25

is it possible when using metafun, given a path to rotate the pen orientation following a different path? e.g. rotating the pen while drawing a line? and/or changing the pen width while drawing? it probably is possible, yet how? Any hints? .Floris

regular online meet-up
by Henning Hraban Ramm 12 Feb '25

12 Feb '25

You’re invited to our regular online meet-up, this upcoming Wednesday, February 12th, 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 always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, 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. * Sometimes leaving and re-entering helps. * 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...

Example, the formular is too much in the middle, should be mor left
by Ursula Hermann 11 Feb '25

Dear List, I have an example, where the formula should be more left. Maybe something with \startalign? setuppapersize[A4] \setcounter[userpage][439] \setupbodyfont[modern, 12.95pt] \setuplayout[backspace=2.9cm, width=13.50cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \definetextbackground[GrayBackground][ location=paragraph, background=color, backgroundcolor=lightgray, leftoffset=.5\bodyfontsize, rightoffset=.5\bodyfontsize, topoffset=.5\bodyfontsize, bottomoffset=.5\bodyfontsize, frame=off,] \starttext \blackrule[color=black, height=0.10ex, width=13.50cm]\dontleavehmode \inrightmargin{\blackrule[color=black, height=0.10ex, width=1.11cm]\par {\bf 7.3.53}} \usecolors[svg] \setupinteraction [state=start, contrastcolor=cornflowerblue] \reference[Abschnitt:1]{7.3.52} {\bi Beweis (von Proposition \goto{7.3.53} [Abschnitt:1]). \tf Die Eigenschaften (i)-(iii) fol-\par gen unmittelbar durch leichte Rechnung aus der Definition. \blank (iv) \space \space Wir berechnen \m u × (\m v × \m w):\nospace \startformula \m u ×(\m v × \m w )=\m u × \startmathmatrix[fences=parenthesis] \NC \m v_2w_3 \NC - \NC \m v_3w_2 \NR \NC \m v_3w_1 \NC - \NC \m v_3w_2\NR \stopmathmatrix \stopformula Many thanks Uschi

compact fonts, fake slanted and \definefallbackfamily (LMTX only)
by Pablo Rodriguez 10 Feb '25

10 Feb '25

Dear list, I have the following sample: \enableexperiments[fonts.compact] \definefallbackfamily [mainface][rm][Dejavu Sans] [sl={style:regular, features:slanted},preset=range:greek] \definefontfamily [mainface][rm][Latin Modern Sans] %[sl={style:regular, features:slanted}] \setupbodyfont [mainface] \starttext αβγ9 some word others\\ \sl αβγ9 some word others \stoptext The only way to get slanted Greek is either with disabled compact fonts, or with fake slanted added to \definefontfamily. I’m experiencing this with LMTX only (MkIV is fine). I’m using current latest (2025.02.07 20:46). Could anyone confirm the issue? Many thanks for your help, Pablo

For some fun, here's a PDF document running linux: https://github.com/ading2210/linuxpdf https://linux.doompdf.dev/linux.pdf (I guess we now only need to make sure that luametatex can run inside the PDF viewer.) Mojca

Dear list, I would like to have chapters in bodypart to list two numbers, the previous to the current page and the current page, such as in: 14 · 15 24·25 50 · 51 100 · 101 I tried the following command, but I cannot get the previous to the current page number: \setuplist[chapter] [pagecommand={\the\numexpr\currentlistentrypagenumber-1\ ·}] What am I missing here? Many thanks for your help, Pablo

matching the same child number (XML)
by Pablo Rodriguez 08 Feb '25

08 Feb '25

Dear list, I have the following way to get text from the current XML node: \xmltext{#1}{.} I would like to have the same results matching the same element. I thought the command should read, but I don‘t get the right results: \xmltext{#1}{../*[match()==lxml.match("#1")]} Minimal sample here: \startbuffer[demo] <root> <div id="one"> <p>first</p> <p>second</p> <p>third</p> </div> <div id="two"> <p>First</p> <p>Second</p> <p>Third</p> </div> </root> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1} {root|div|p} {xml:*} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:root \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:div \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlmatch{#1}: \xmltext{#1}{.}\\ \xmltext{#1}{../*[match()==lxml.match("#1")]} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext How could I match only the current n-th child? Many thanks for your help, Pablo
