regular online meet-up
by Henning Hraban Ramm 08 May '24

08 May '24

You’re invited to our regular online meet-up, this upcoming Wednesday, May 8th, 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? I’m hoping to hear about BachoTeX (have fun, everyone who’s there)! 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...

more register questions!
by Thomas A. Schmitz 08 May '24

08 May '24

Hi, making wonderful progress on my registers and translating from xml. There is one thing I can't figure out (and I or some other good soul may have asked in the past...). Is it possible to mark occurrences in footnotes? Ideally, the entry in the register would look like p. 100\high{20} to show that the term occurs in note 20 on p. 100. But if that's asking too much, I would be content with applying a processor (say, italic) to these register entries. From the looks of the tuc file, Context doesn't appear to "know" that a register entry is within a footnote. But Hans never ceases to amaze me, so maybe there is a way (short of applying special markup to these notes in the source)? All best Thomas

transparent color
by Hans van der Meer 06 May '24

06 May '24

I would like to use a transparent version of an existing color. Thus \definecolor[transparentcolor][color,t=0.2,a=1] instead of \definecolor[transparentcolor][r=..,g=..,b=..,t=0.2,a=1] because I do not know the rgb values of the color that must be made transparent, only its name. How to accomplish? yours sincerely dr. Hans van der Meer

Why is this description environment not showing the correct title?
by Joel 05 May '24

05 May '24

\definedescription[latexdesc][headstyle=bold, style=normal, align=flushleft, alternative=hanging, width=broad, margin=1cm] \starttext \latexdesc{1540} some event happened \latexdesc{1541} some other event happened \latexdesc{1542} some event happened quite different \stoptext I found the above code (the first line) in the ConTeXt Wiki, as a way to create the equivalent of a desc environment from LaTeX. The items inside {} should be bold, then there is a gap before the next text. I am using this to display a simple timeline. Though the formatting looks perfect, very strangely when I compile it, it changes all of the dates to say "1540" (or whatever date was used first). Why is it showing the wrong title on the desc environment? --Joel

How to stop ConTeXt from thinking period is at the end of a sentence?
by Joel 05 May '24

05 May '24

I noticed that some code is being rendered wrong, most especially apparent in a column environment where sometimes the text can get stretched a bit more to fit the column width nicer. If a sentence says "They appeared between c. 1200 BCE and c. 1500 CE." it appears ConTeXt thinks that the period in "c." marks the end of a sentence. As such, when setting the text, sometimes it will give a large space between "c." and "1200 BCE". How do I correctly tell ConTeXt that that period doesn't mark the end of a sentence, so shouldn't be given extra space afterwards? --Joel

Switch number and enumeration text
by Jethro Djan 04 May '24

04 May '24

Dear List, I would like to get something like: 1.1 Theorem instead of Theorem 1.1. Seems simple enough but can't figure out how to switch the number and the text. I have the following MWE: \defineenumeration[theorem][ prefix=chapter, text=Theorem, style=italic, headstyle=bold, headcommand=\groupedcommand{}{.}, ] \starttext \chapter{} \section{} \starttheorem This is a theorem \stoptheorem \stoptext Many thanks, Jethro

How to obtain the hbox's node when there is only one hbox for an entire paragraph?

\par and \startlines
by denis.maier＠unibe.ch 01 May '24

01 May '24

Hi, I'm trying to typeset a poem from XML, but I can't figure out how to make the inbetween key working here. As the source is XML, I cannot just add an empty line to start a new group of lines inside \startlines...\stoplines. I guess, there must be a command to do that, but \par seems to have no effect here. How can this be done? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuplines[before={\blank},after={\blank},inbetween={ARE WE INBETWEEN?\blank}] % XML Nodes auswählen \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{doc|poem|stanza|line}{xml:*} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:poem \startlines \xmlflush{#1} \stoplines \stopxmlsetups \startxmlsetups xml:stanza \xmlflushlinewise{#1}\par %this has no effect \stopxmlsetups \startxmlsetups xml:line \xmlflush{#1} \stopxmlsetups \startbuffer[test] <?xml version='1.0' standalone='yes?> <doc> <poem> <stanza> <line>The</line> <line>lines</line> <line>are</line> <line>there!</line> </stanza> <stanza> <line>The</line> <line>lines</line> <line>are</line> <line>there!</line> </stanza> </poem> </doc> \stopbuffer \starttext This works: \startlines The lines are there!
