How can I wrap an externalfigure into a box that can be placed within running text? Should I wrap the externalfigure into a start/stop buffer, then place it? Some hints? .Floris

I see many libraries for Metapost in Context source. Where are these documented? I see Metafun manual as well, but I do not find all the included libraries described. -- Respect, Shiv Shankar Dayal

Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

regular online meet-up
by Henning Hraban Ramm 10 Jan '24

10 Jan '24

A happy & healthy new year! You’re invited to the first online meet-up of the year, this upcoming Wednesday, January 10th, 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. * 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...

Width of captions and notes in outer margin not correct on even pages
by Milan cel Mare 09 Jan '24

09 Jan '24

Hi, I have observed that the widths of captions and also notes on even pages is not as I would expect them to be. Reading through the documentation I figured out that the width for captions has to be set manually when they are placed in the outer margin. I did so by setting it to width=\outermarginwidth. But it seems that for captions the width is derived from the inner margin width on even pages. The width of notes in the outer margin placed with \inouter is also off on even pages. They are too narrow and do not "fill" the available space (things seems to work for notes in inner margins though). Here is an example: \setuppapersize[A4] \setuplayout[backspace=40mm, width=100mm, leftmargindistance=5mm, leftmargin=30mm, rightmargindistance=5mm, rightmargin=50mm, topspace=10mm] \setuppagenumbering[alternative=doublesided] \setupcaptions[location={outermargin, low}, width=\outermarginwidth, headcolor=red, color=green, style={\tfx\setupinterlinespace}, align=width] \setupexternalfigures[location=default] \setupmargindata[style={\tfx}, stack=yes] \setupmargindata[inouter][color=orange] \setupmargindata[ininner][color=blue] \showframe \starttext \section{Margin Tests} \input knuth Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read\inouter{Another multi-line text to be placed in the outer margin to check whether it is positioned correctly.}. \startplacefigure[title={A lengthy caption perfectly suited to perform some tests, which cause lines to wrap.}] {\externalfigure[cow][maxwidth=80mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.}. \input zapf Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read. \startplacefigure[title=A SVG test with a long caption to cause line wraps.] {\externalfigure[cow][maxwidth=70mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.} to read. \input knuth \stoptext As a workaround the width for captions can be set to width=\rightmarginwidth, but how can I solve the issue with the notes? I am running ConteXt 2023.09.26 18:19 on Windows 10. Thanks and best regards Milan

Hello, Happy New Year! I got into a bug in my Vim syntax highlighting version. Highlight stays in lua mode after ctxlua macro is closed. Here is a MWE, where «this should not be highlitghted as a comment indeed is. \starttext Hello! \ctxlua{context("does the parser work?")} -- this should not be highlighted as a comment \stoptext Do other Vim users come into this? Is my syntax file outdated? I am using this Vim version on OpenBSD 7.3 -stable: VIM - Vi IMproved 9.0 (2022 Jun 28, compiled Sep 6 2023 08:55:14) Included patches: 1-1876 Best regards, Damien Thiriet

Setuphead issue!
by G.C.H.M. Verhaag 09 Jan '24

09 Jan '24

Hi, I'm a bit puzzled by the mkiv /setuphead/ command of ConTeXt! The space *before* and *after* the /subject/ command can usually be set by the *before* and *after* arguments of the /setuphead/ command. Now I'd like to have _no vertical space_ before and after the header. I've tried just that by setting either *before=* and *after=* and *before=\blank[none]* and *after=\blank[none]*. But none of these seem to work. Any idea? Gerard --

Dear List, Is this the right way? I want to use linked bibliography numbers, linked Chapter, section subsection, linked margin numbers, in the text. \setupinteraction[state=start] \starttext Der Wert von \m{y = f(x)} ist unabhängig von der Wahl\par von \m{x\doubleprime} ist gleichbedeutend mit \m{∃y : ∀x : f(x) = y} \par (Beutelspacher [\hyphenatedurl {10},S.54]). \stoptext Many thanks Uschi

MetaFun path joiners && and &&&& do not like single point paths
by Gavin 09 Jan '24

09 Jan '24

Hi MetaFun fans, Following a suggestion of Hans, I experimented with && and &&& and &&&& for joining paths in MetaFun. The joiner &&& produces one long path, but && and &&&& seem to produce a disconnected path which includes all the original paths. However, if one of the paths is a single point, then it connects it. MWE below. I spotted this on my globes module, where we saw an extra line appear for a very specific orientation of the globe. I guessed that this orientation had an island right on the horizon, so that only one boundary point was visible, creating a singe point path for that island. I should probably fix my module so it doesn’t do that. However, it might be nice to have && and &&&& deal with this situation gracefully. Gavin \startMPpage path p[], q ; p1 = fullcircle scaled 3cm ; p2 = fullcircle scaled 2cm shifted (3cm,0) ; p3 = (3cm,2cm) ; q = for i = 1 upto 3 : p[i] && endfor cycle ; draw p1 withpen pencircle scaled 2pt withcolor .7 ; draw p2 withpen pencircle scaled 2pt withcolor .7 ; draw p3 withpen pencircle scaled 2pt withcolor .7 ; draw q withcolor red ; eofill q withcolor 0.9 ; draw fullcircle scaled 6cm shifted (1.25cm,0) ; \stopMPpage
