new upload

Hi, I uploaded a new lmtx. Apart from a experimental intersection feature in the mp library (and metafun, more will be revealed when MS an I are okay with it) there is not that much news. I decided to turn some test code into a mechanism which is illustrated below. Adaptive boxes are hboxes that act a bit like glue which means that when we hook in e.g. a graphic it can be made to adapt. We can add some more methods if needed so maybe you see other usage. The interface is rather lightweight and the overhead is quite resonable.

Re: [NTG-context] right item marks for associative questions?

> You can use different alignment settings to move the bullet points to > the right side of your lists. Thank you Wolfgang, this is exactly what I need. One more question: I am typesetting those questions in lua, because lua vectors were more convenient for reading the whole but I am not sure how should I pass the righttoleft option. I read the cld manual and my guess is I should use function() but looks like I lack some understanding of context proceeding. This is what I did so far \startluacode userdata = userdata or {} function ListeAleatoireGauche(t) context.startitemize {"8","packed","random"} for k=1,#t do context.startitem() context.lefttoright(t[k]) context.stopitem() end context.stopitemize() end function ListeAleatoireDroite(t) context.startitemize {"8","packed","random"} for k=1,#t do context.startitem() context(t[k]) context.stopitem() end context.stopitemize() end function QCMAssociatif(t,u) context.startxtable {"frame=no","columndistance=3cm"} context.startxrow() context.startxcell() ListeAleatoireGauche(t) context.stopxcell() context.startxcell() ListeAleatoireDroite(u) context.stopxcell() context.stopxrow() context.stopxtable() end \stopluacode \starttext \startluacode Author = {"Nietzsche","God"} Quote = {"God is dead","Nietzsche is Dead"} QCMAssociatif (Author,Quote) \stoptext Damien Thiriet

fatal error in LMTX
by Pablo Rodriguez 13 Apr '22

13 Apr '22

Hi Hans, I have a minimal sample that triggers a fatal error in ConTeXt LMTX (current latest from 2022.04.11 19:27): \starttext \startfrontmatter \input zapf \stoptext This gives the following error message: mkiv lua stats > runtime: 0.386 seconds, 1 processed pages, 1 shipped pages, 2.592 pages/second mtx-context | fatal error: return code: 1 The one above is a stupid sample. But it took me about two hours to discover what was triggering the fatal error message. I wonder whether it would be possible that ConTeXt or LuaMeTaTeX could be more verbose about an opened environment that isn’t closed. Many thanks for your help and your excellent work, Pablo

Lorem ipsum module line limit
by A A 13 Apr '22

Hello, I am trying to fill up an entire page with dummy text using m-ipsum. Unfortunately, it looks like m-ipsum only allows up to 12 lines, if I increase it to 13+ lines I see no change in the resulting PDF file: *\usemodule[m-ipsum]\starttext \ipsum[alternative=lines, n=12]\stoptext* Is this intended behavior or a bug. How can I fill up the whole page with dummy text? Amine

Proper formatting of itemized bullets in ConTeXt
by A A 13 Apr '22

13 Apr '22

Dear All, Is there a straightforward way of setting up the itemize command such that every first letter is capitalized, regardless of whether I do so in the source file? Also, is there a way to insert a comma at the end of each item except for the last, and then a full stop at the end of the last item like follows? - First item, - Second item, - Third item, - Last item. Thanks in advance. Amine

Thank you for all your answers. I will have a deeper look at them. My first comments: > If you are certain that the there will be no > multi-line item Unfortunately there are often some. History teachers are not known for loving short texts, at least in France. > Using the “columns" feature is one way to go Might be, but I do not always give the same number of answers on both columns Something I forgot to put in my MWE is that I randomize both lists. Messing the answers is a good way to prevent pupils from cheating, especially with long answers.. That makes a four columns table more cumbersome, so I believe. Damien

Flaw in Vim syntax highlighting
by A A 12 Apr '22

12 Apr '22

Hello, I have discovered a flaw in the syntax highlighting for ConTeXt in Vim. When trying to follow the *A larger Lua block: \startluacode...\stopluacode * in this link in Context Garden <https://wiki.contextgarden.net/Programming_in_LuaTeX>, I get the following syntax highlighting: [image: image.png] Who develops the syntax highlighting for Vim? Is this part of the core project or should I log this issue elsewhere? Regards, Amine

right item marks for associative questions?
by Damien Thiriet 12 Apr '22

12 Apr '22

Hi! I am used to giving associative questions to my pupils, something like * connect the author with its ideas Friedrich Nietzsche * * "God is dead" Woody Allen * * "Nietzsche is dead, God is dead and I don't feel so good" God * * "Nietzsche is dead" I design it as a two-cells xtable with itemized lists inside. How can I have the item mark on the right side? \starttext \startitemize [8] \startitem Nietzsche \stopitem \startitem Allen \stopitem \startitem God \stopitem \stopitemize \stoptext Greetings, Damien Thiriet

Regular online meet-up
by Henning Hraban Ramm 11 Apr '22

11 Apr '22

You’re invited to join next Tuesday, February 8th, 15:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! Hans offered to give a Q&A session again – please announce subjects you’d like to discuss ASAP, so that he can prepare. Regarding the date: Denis, who originally suggested Tuesday afternoon, can’t take part due to other obligations. I could also offer Wednesday or Thursday. We could also change the weekday every time, but that might be confusing. I would keep the European afternoon time, since that makes participation possible for people from America and Asia. What do you think? Vote here: https://nuudel.digitalcourage.de/tB1MHH4jx6M5uwPg (Same blurb as last 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, 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. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * You can also join with a regular telephone (audio only, of course), call +49-6151-86275-22 (German landline); then you must enter a PIN that changes every time – if you need it, ask me for it via email. Mute/unmute your microphone with "0". [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... See you, Hraban
