TIL: figure combinations
by Henning Hraban Ramm 11 Aug '22

11 Aug '22

You probably know about combinations to place images side by side: \startcombination[3*1] {\externalfigure[cow]}{cow} {\externalfigure[mill]}{mill} {\externalfigure[hacker]}{hacker} \stopcombination Now, the widths aren’t calculated automatically. You could define them on your own: \startcombination[3*1] {\externalfigure[cow] [width=.3\textwidth]}{cow} {\externalfigure[mill] [width=.3\textwidth]}{mill} {\externalfigure[hacker][width=.3\textwidth]}{hacker} \stopcombination But that’s ugly and tedious. Hans did it for you: \definemeasure[combination][ (\textwidth -\effectiveleftskip -\effectiverightskip -\numexpr\combinationparameter\nx-\plusone\relax\dimexpr\combinationparameter\distance\relax )/\combinationparameter] So you can say: \startcombination[3*1] {\externalfigure[cow] [width=\measure{combination}]}{cow} {\externalfigure[mill] [width=\measure{combination}]}{mill} {\externalfigure[hacker][width=\measure{combination}]}{hacker} \stopcombination But that’s still tedious. With the power of \defineexternalfigure: \defineexternalfigure[combination][width=\measure{combination}] (That’s predefined, no need to copy!) \startcombination[3*1] {\externalfigure[cow] [combination]}{cow} {\externalfigure[mill] [combination]}{mill} {\externalfigure[hacker][combination]}{hacker} \stopcombination Beautiful. ;) Have fun, Hraban

How to display these characters
by juh+ntg-context＠mailbox.org 10 Aug '22

10 Aug '22

Dear all, I have this: \starttext \starttyping foo └── bar ├── baz │ └── index.html └── index.html \stoptyping \stoptext The source code is generated with the linux command "tree". The special characters which indicate the folder depth are not displayed. I guess that I could define a fallbackfont. Do anyone know the unicode range that should be covered and the font that has these characters? TIA juh

MetaFun keywords extracted by mtxrun --script interface
by Nicola 10 Aug '22

10 Aug '22

I am updating Vim syntax coloring for Metapost/MetaFun, which is now based on the files that are automatically generated with mtxrun --script interface --vim To test the results, I am opening ConTeXt's own MetaPost files in the editor and check how they look. It seems that the output of the above command is missing several "keywords". For instance: beginglyph, endglyph, anglestriped, numberstriped, roundedsquarexy, starring, dashing, pathpoint, primitive, immutable, etc. Is it because MetaFun keywords are picked up manually?

regular online meet-up
by Henning Hraban Ramm 10 Aug '22

10 Aug '22

You’re invited to join next Wednesday, August 10th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! There will be no meet-up in September (since it would be during the ConTeXt meeting); and then on October 12th. (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, 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

underbrace under matrix
by Jethro Djan 05 Aug '22

05 Aug '22

Hello, I want to get underbraces under matrices in a math alignment environment. I’ve reproduced my problem here: \definemathmatrix [pmatrix] [left={\left(\,},right={\,\right)}] \starttext \placeformula[-]\startformula\startmathalignment \NC\ A \NC=\underbrace{ \startpmatrix \NC 5\NC 5\NR \NC -1\NC 7\NR \stoppmatrix}\NR \NC\NC=\underbrace{ \startpmatrix \NC 2\NC 1\NR \NC 4\NC 2\NR \stoppmatrix}\NR \stopmathalignment\stopformula \stoptext How can I achieve this?

math symbols
by Hans Hagen 05 Aug '22

05 Aug '22

Hi, We're curious what math symbols users actually use. There are for instance all kind of variations on '<' and '>' and the quesiton is: how should we group them and are they used differently in different contexts. Traditionally tex sort of groups according to spacing related classes but we are (1) mor egranular than that and (2) like to organize symbols (and related commands) into meaning related groups. The fact that for instance mathml and openmath only groups a small selection is kind of puzzling because it means that only a handful is considered useful while on the other han dwe have plenty in unicode and fonts (of course multiple usage and overloads complicate matters). We'd like to sort out some of the mess that the tex community accumulated over decades and are not that bound to conventions, more to a well organized whole, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

issue with lpath
by Pablo Rodriguez 05 Aug '22

05 Aug '22

Dear list, I have this sample: \startbuffer[demo] <xml> <div class="section level3"> <h3>One</h3> <p>Standard paragraph</p> <blockquote> <p>Quoted text</p> </blockquote> </div> <div class="section level3"> <h3>Two</h3> <blockquote> <p>Direct quote</p> </blockquote> </div> </xml> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1} {p|blockquote} {xml:*} \xmlsetsetup{#1} {(div|section)[contains(@class,'level3')]/h3/../!p/../h3} {xml:section} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:p \startpar\xmlflush{#1}\stoppar \stopxmlsetups \startxmlsetups xml:blockquote \startblockquote\xmlflush{#1}\stopblockquote \stopxmlsetups \startxmlsetups xml:section \section{\xmlflush{#1}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext I need an lpath to select the h3 node above, but only the one with "h3 + blockquote" as a CSS selector (which could be added the lpath "../h3" after). It would be "<h3>Two</h3>" and not "<h3>Two</h3>" in this sample. Excuse my ignorance, but which is the way to achieve this? Many thanks for your help, Pablo
