[NTG-context] regular online meet-up
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... ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

[NTG-context] Re: multipage metapost output from ConTeXt
Hi Mikael,
with the solution provided by you, I could work on my graphic which grows from
page to page. So far I have already 28 pages. Now I would like to go back to
the summed graphic of p1 to p21 and add the coming p29, p30 etc. to only that
(that means contents of p22 to p28 should not be visible on pages 29 and
forward).
I don't bother you with my code which is too long. Let's use the mwe provided
by you (I added it here for convenience), where we have 3 pages. How can I have
the content of p2 not be added on page 3 and forward?
\startuseMPgraphic{base}
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);
p1:=image(
label("Word 1", z1);
);
p2:=image(
label("Mot 2", z2);
);
p3:=image(
label("Parola 3", z3);
);
\stopuseMPgraphic
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
\includeMPgraphic{base}
currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="(currentime)) scaled 2 shifted(0,2in)
withcolor magenta ;
for k=1 upto currentime: addto currentpicture also p[k]; endfor
setbounds currentpicture to TheFrame ;
desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );
\stopMPpage
}
\stoptext

[NTG-context] Re: vim syntax highlighting bug?
Hello
on my installation, it's working:
[image: image.png]
But I'm on an old version on debian:
VIM - Vi IMproved 8.2 (2019 Dec 12 kompiliert am Oct 01 2021 01:51:08)
Inklusive der Patches: 1-2434
Extra Patches: 8.2.3402, 8.2.3403, 8.2.3409, 8.2.3428
Perhaps something has changed in version 9.0...
Hope it helps

[NTG-context] vim syntax highlighting bug?
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
