Back in the 90s
by Riviera Taylor 13 Apr '24

Hello, I was reading about the history of ConTeXt in the Not So Short Introduction To ConTeXt and I have a historical question. I noticed that the PDF specification was published in 1993 yet ConTeXt was invented in 1991. The book suggests that PDF output was handled by the PdfTeX engine in MKII in 2005. What sort of output did the software produce before PdfTeX was introduced? Was this the same as the output produced by the software before the publication of the PDF specification? Kind regards, Riviera she, her, hers https://wiki.contextgarden.net/User:River

\luaescapestring in proper Lua
by Pablo Rodriguez 11 Apr '24

11 Apr '24

Dear list, I have the following sample: \starttext \startluacode function document.print_the_thing(str) context(str) end \stopluacode \unexpanded\def\PrintTheThing#1{% \ctxlua{document.print_the_thing([[\luaescapestring{#1}]])}} \PrintTheThing{a \em b {c}} \stoptext I wonder whether there is a proper way in the Lua code to avoid [[\luaescapestring{}]] in \ctxlua. BTW, [[\luaescapestring{}]] in \ctxlua works better for me, since in my real world document, I’m using str:match() to check whether the string ends with interrogation or exclamation marks ("%?!$"). Many thanks for your help, Pablo

Weird (?) float placement for specific widths of image
by denismaier＠mailbox.org 10 Apr '24

10 Apr '24

Hi, another graphics/floats question: consider the following example %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupexternalfigures [location={local,global,default}] \starttext \placefigure{A Cow}{\externalfigure[cow][ height=.5\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ height=.3\textheight, %height=.4\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ width=3cm, %width=2cm, ]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \stoptext%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% On the first page, the images appear stacked above each other while on the second page they appear next to each other. It took me some time to reproduce this behaviour, and I can't claim to understand what is happening. But it seems to be related to the specific widths of the images. When I change them to other values the behaviour disappears. Is this a bug? Anything I can do about this? Best Denis

You’re invited to our regular online meet-up, this upcoming Wednesday, April 10th, 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? 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...

Very bizarre bug
by Thomas A. Schmitz 07 Apr '24

07 Apr '24

Hi everybody, this is bizarre, but hear me out: a file that I have has a mixture of xml, TeX and Lua. It compiles cleanly, no problem, on macos and linux. I also have a little raspberry pi on which I have installed lmtx. The file compiles, BUT: it has one additional page. The first page of the document is empty and has the word "on" in the upper left hand corner of the text area. I have checked several times, it always comes out like this. Everything else is exactly the same - context version, file and environment files (everything under git, so really identical). The "on" does not appear if I just make a "hello world" document on the raspi. So my question is: how can I begin to explore where this word creeps in? I suspect it's something in the linux-aarch64 tree or some test for this architecture that is the culprit, but what would be a good way to trace it? All best Thomas
