regular online meet-up
by Henning Hraban Ramm 14 Aug '24

14 Aug '24

Even if it’s just a few days before our in-person context meeting: You’re invited to our regular online meet-up, this upcoming Wednesday, August 14, 19:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Do you have a subject that you’d like to talk about? Is there something we should discuss before the Lutten meeting? 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...

Missing \endcsname inserted error
by Jeong Dal 13 Aug '24

Hi, I draw a figure using MetaFun and insert it \startplacefigure and \stopplacefigure. (Sample file is listed below) But, I got an error as following: Missing \endcsname inserted <to be read again> \defcsname <macro> \mult_interfaces_get_parameters_item_okay #1=#S#2,->\ifarguments \or \mult_interfaces_get_parameters_item_error {#1}\else \defcsname \m_mult_interfaces_namespace #1 \endcsname {#2}\fi <macro> \mult_interfaces_get_parameters_item #*#S#1,->\ifarguments \expandafter \gobbleoneargument \else \mult_interfaces_get_parameters_item_okay #1, If I remove "\startplacefigure and \stopplacefigure”, then there is no error, but the figure is not centered. Please tell me how to fix it. Thank you for reading. Best regards, Dalyoung \startbuffer[numbers] path p,q; p = unitsquare xyscaled(3,2) superellipsed .85 ; q := p scaled 1cm; draw q; label.bot(textext("\naturalnumbers"), point 2 of q); q := p scaled 1.5cm shifted (-.75cm,-.2cm); draw q ; label.bot(textext("\integers"), point 2 of q); q := p scaled 2cm shifted (-1.5cm,-.4cm); draw q; label.bot(textext("\rationals"), point 2 of q); q := p scaled 2.5cm shifted (-2.25cm,-.6cm); draw q; label.bot(textext("\reals"), point 2 of q); q := p scaled 3cm shifted (-3cm,-.8cm); draw q; label.bot(textext("\Bbb C"), point 2 of q); \stopbuffer \starttext \startplacefigure[location=none,\title=] {\scale[scale=1400]{\processMPbuffer[numbers]}} \stopplacefigure \stoptext

Complete novice, why does it seem that LuaLaTeX (Compiled via LaTeX Workshop with MikTeX and added packages on Windows) will generate a more compact result than ConTeXt?
by fm117575＠students.panola.edu 13 Aug '24

Hello, ConTeXt mailing list! I have a question regarding a difference in the code that I have which uses the same paper size and margin settings, and also the same indentation rules and font size and font. It seems that ConTeXt (which I compiled via Windows Terminal, this *is* the proper way to compile ConTeXt docs, right?) seems to make text that is less... compact, and I am not sure if this is due to me not adding features that I **should** have turned on in ConTeXt when using Times New Roman that is installed by default on Windows. I also was not able to get a "proper (?)" single quote like when Word or LaTeX compiles "Don't", that ' is a straight quote in the compiled text. I also heard that ConTeXT would be much better for typography since it does have a more advanced typographical engine as the base (and this is a big reason as to why I want to switch to ConTeXt, pretty much everything is built in, I just can't understand documentation that well), and this may be because my code is very basic and I do not know how do properly do ConTeXt. Is it possible that ConTeXt also has a more "correct" way of formatting? Anyways, thank you for reading and taking the time to read this post.

no escaping with scite highlighting any more?
by Henning Hraban Ramm 11 Aug '24

11 Aug '24

Hi, this used to work: """ \usemodule[scite] % the setup doesn’t change the behavior, I think it used to. \setuptyping[TEX][ option=tex, % scite sets "cld" ] \starttext \startTEX[escape=yes] \definemeasure[PageWidth][165mm] /BTEX\hfill{\ss Dimensions}/ETEX \definemeasure[PageHeight][239mm] \definepapersize[DANTE][ /BTEX\hfill{\ss Paper size}/ETEX width=\measure{PageWidth}, height=\measure{PageHeight},] \setuppapersize[DANTE] \stopTEX \stoptext """ Without the scite module, escaping in \startTEX works, but I need the module for some other highlighters. Is there a solution? Hraban

Breakable tcolorbox in ConTeXt
by Florent Michel 11 Aug '24

11 Aug '24

Hi, I am trying to reproduce the behaviour of the tcolorbox LaTeX package, more specifically breakable boxes (as illustrated here: https://tex.stackexchange.com/a/676607/123770) It works nicely out of the box (pun intended) using `\definetextbackground` and drawing the frame with MetaPost, using counters to keep track of whether the current text is at the top, middle, or bottom of the box. However, I'm having issues when one box ends and another starts on the same page (see more details below). From what I understand, the issue is that counters seem to be updated on a page-wide basis, so each MPgraphic ‘sees’ the values of counters at the end of the current page, which may not be right if another box modifies them. Would anyone know how to resolve this? Based on two answer on TeX StackExchange ( https://tex.stackexchange.com/a/486124/123770 , https://tex.stackexchange.com/questions/377234/context-frame-problems/37726…) the following code works well if there is no more than one box per page: ``` \definecounter[pageNumberTop] \definecounter[pageNumberBottom] \startuseMPgraphic{mp:axiomframe} begingroup; for i=1 upto nofmultipars : path p; p := ( llcorner multipars[i] -- lrcorner multipars[i] -- urcorner multipars[i] -- ulcorner multipars[i] -- cycle ) enlarged (EmWidth,EmWidth) ; fill p withcolor boxfillcolor ; % if the current page is the first one covered by the box... if (\pagenumber == \rawcountervalue[pageNumberTop]) : % ... if it is also the last one, the box fits entirely on the page; we thus draw the full frame if \rawcountervalue[pageNumberTop] == \rawcountervalue[pageNumberBottom] : draw p withpen pencircle scaled 2pt withcolor boxlinecolor ; % ... otherwise, don't draw the bottom line else : draw llcorner multipars[i] + (-EmWidth, -EmWidth) -- ulcorner multipars[i] + (-EmWidth, EmWidth) -- urcorner multipars[i] + (EmWidth, EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; fi ; picture pic; pic := textext.ulft("\tfd\symbol[info]"); pic := pic shifted ulcorner multipars[i]; fill bbox pic withcolor white; draw pic; % if the current page is the last one covered by the box, draw the left, bottom, and right lines elseif \pagenumber == \rawcountervalue[pageNumberBottom] : draw ulcorner multipars[i] + (-EmWidth, EmWidth) -- llcorner multipars[i] + (-EmWidth, -EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) -- urcorner multipars[i] + (EmWidth, EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; % if the current page is neither the first one nor the last one, only draw the left and right lines else : draw llcorner multipars[i] - (EmWidth, EmWidth) -- ulcorner multipars[i] + (-EmWidth, EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; draw urcorner multipars[i] + (EmWidth, EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; fi ; endfor ; setbounds currentpicture to OverlayBox ; endgroup; \stopuseMPgraphic \definetextbackground [theoremFrame] [mp=mp:axiomframe, location=paragraph, backgroundcolor=green, framecolor=red, before={\setcounter[pageNumberTop][\pagenumber]}, after={\setcounter[pageNumberBottom][\pagenumber]}] \definestartstop [ColoredBox] [before={\blank[2em]\starttheoremFrame}, after={\stoptheoremFrame\blank[2em]}] ``` For instance, ``` \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` correctly gives a box split over multiple pages, with the top part of the frame only drawn on the first page and the bottom part only drawn on the last one. It also works correctly when adding `\page` between boxes: ``` \starttext \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox \page \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` However, the following gives an incorrect output: ``` \starttext \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` On page 3, both frames are fully drawn while the first box is a continuation of the one on the previous page and the second one is the start of a box continuing on the next page. I tried several variations without success; my main issue is that (if I understand correctly) the values of counters are the same for the two boxes on page 3, so that at least one of them will be wrong. If someone has any ideas on how to resolve this, I'd be really grateful! Alternatively, if someone has a solution using Tikz, that would also work - I'd ideally use MetaPost as the tight integration with ConTeXt seems (from my short experience) to make many things easier; but any solution using ConTeXt + a small number of other dependencies is fine. Cheers, Florent
