Footnote in a cell inside a row into a table !
by Jean-Pierre Delange 11 Oct '24

11 Oct '24

Dear users, I'm struggling with a bibliographic reference that I want to integrate after a name that happens to be in a cell, itself located in a table. All my code works, except for the bibliographic reference given by the footnote and the \cite command. Here's the line as it appears in my code: \startxtable[option=stretch, align={middle,lohi}, frame=off, distance=0.5em] \startxrow \startxcell \em Ambrosianus\footnote{Cf. \cite[alternative=entry][Bibliography::mai1]} \stopxcell \stopxrow \stopxtable All preliminary declarations into the file are made correctly, as is the backmatter. The PDF output is correct, but the bibliographic reference is not displayed. I seem to vaguely remember a message pointing out a similar difficulty. By coding the bibliographic reference outside the cell, the whole text display is correct, but the bibliographic reference is not displayed. I’m testing this code under Mac OSX : system > ConTeXt ver: 2022.01.06 19:51 LMTX fmt: 2022.1.7 int: English/English and I’m satisfied with the work it is doing. Any idea about what I could looking for ? Many thanks ! JP

Re: Lua <-> TeXShop

Thank you very much, Hans, I had already written to Dick Koch before the first replies arrived. He wrote that I could simply use Lua(La)TeX. So it works with Lua(La)TeX. A self-created lua.engine works and your ConTeXt solution with --runner=mtxrun in the first line works as well.

penalties
by Henning Hraban Ramm 10 Oct '24

10 Oct '24

Yesterday I learned: \startsetups[*default] \widowpenalties 3 10000 1000 0 \clubpenalties 3 10000 1000 0 \orphanpenalties 2 8000 1000 \stopsetups If I want the penalty settings applied to “everything” (after defining the layout, I think?), then I need the setup "*defaults". Since TeX uses a club against orphans (brutal!), I’m not sure what \orphanpenalty is for. I remember \twinpenalty is against doubled words (below each other?), and \toddlerpenalty against single letter words at the end of a line (why “toddler”?). widows and clubs get only 150 in TeX, but 2000 in ConTeXt, as far as I could find. Are there more penalties that make sense to set individually? WRT demerits: Did I understand correctly that demerits are the “sum” (some formula) of badness and penalties in a line or paragraph?

widows and orphans in \definestartstop?
by Florian Grammel 09 Oct '24

09 Oct '24

I have defined a simple environment for verse within prose-context. Obviously I never want the first or last lines of the verses to stand as widows or orphans. I could just add \nobreak to every first and last line of verse to achieve this. But I was wondering whether I could change anything of my \definestartstop to do this automatically. Simply adding \nobreak to before= and after= doesn't work. Thank you all for your time! Best, Florian. \definestartstop [origverse] [before={\startnarrower[left,right]\startlines}, after={\stoplines\stopnarrower % \setupindenting[next] %\indenting is deprecated! \blank}] \startdocument prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose \startorigverse vvvvvvvvvvvvvvvvvvvvvvv vvvvvvvvvvv vvvvvvvvvvvvvvvvvv vvvvvvvv vvvvvvvvvvvvvvvvvvvvvvvvvvv vvvvvvvvvvvvvvvv vvvvvvvvvvvvvvvvvvvvvvvvvvvvv \stoporigverse prose again prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose prose \startorigverse vvvvvvvvvvvvvvvvvvvvvvv vvvvvvvvvvv vvvvvvvvvvvvvvvvvv vvvvvvvv vvvvvvvvvvvvvvvvvvvvvvvvvvv vvvvvvvvvvvvvvvv vvvvvvvvvvvvvvvvvvvvvvvvvvvvv \stoporigverse prose again ____________________________________________ Florian Grammel Copenhagen, Denmark

Hello, at the risk of this being the wrong address: can I edit and run Lua with TeXShop? Does anyone have experience with this? Or what could be used as an IDE for Lua? Greetings Thomas

Downsampling images (again)
by Henning Hraban Ramm 09 Oct '24

09 Oct '24

This is lying around for years, let’s try to get it finally working. The code below works, but doesn’t do the right thing. Since the original image doesn’t contain a resolution setting, gm doesn’t do anything: “gm convert: image does not contain resolution” It would be more reliable to use “gm convert -resize”, but for that we need to know the final pixel size. How can a converter function access … – the final (scaled) size of a placed image – the original pixel size of an image ? With that information it would be easy to calculate the target pixel size. And then it would be nice to hook this function into \setupexternalfigure[conversion=] """ \startluacode local function downsampler(oldname, newname, resolution) if not resolution or resolution == "" then resolution = 72 end local cmd = string.format( [[gm convert -resample %ix%i "%s" "%s"]], resolution, resolution, oldname, newname) logs.report("downsample", cmd) os.execute(cmd) end -- Set the PDF and default JPEG converters to the above function. figures.converters.jpg.pdf = downsampler figures.converters.jpg.default = downsampler \stopluacode \setupexternalfigure[ %conversion=downsampler,% not used resolution=10, ] \starttext \externalfigure[https://upload.wikimedia.org/wikipedia/commons/d/dd/Hermann_Zapf_signing.jpg][width=.5\textwidth] \stoptext """ Hraban

fixing kerning and substitutions
by Florian Grammel 09 Oct '24

09 Oct '24

I am trying to reuse code of a project from 2017 with TL23 context. (Other questions probably coming up...) Back then I used font handlers to fix some smaller problems in the font, i.e. a wrongly placed small capital and missing kerning for the small caps. The following code works with context 2017.04.27 01:00 MKIV beta but has stopped having any effect using recent context (2023.05.05 18:36 LMTX). There are no error messages. Has the syntax changed? Or is the functionality dropped completely? I was also wondering why it has never been working to adjust the kerning for the regular letters, e.g. "A" and "V" in the example, neither in 2017 nor today. Thanks a lot in advance! Florian. \definefontfamily [mainface] [serif] [Palatino Linotype] [oldstyle] \setupbodyfont [mainface] %\feature[+][oldstyle] %\feature[+][kernup] %works with Context beta from 2017, doesn't work with TL 2023 \directlua{ fonts.handlers.otf.addfeature { name = "smcp", type = "alternate", data = { ['eth'] = 'Eth.ordn' , % ['k.smcp'] = 'Ķ' , }, } } %works for the smcp with Context beta from 2017, doesn't work for the regular capital letters %doesn't work at all with Context TL 2023 \directlua { fonts.handlers.otf.addfeature { name = "kern", type = "kern", data = { ["A"] = { ["V"] = 1500 }, ["P"] = { ["Æ"] = 1500 }, ["a.smcp"] = { ["s.smcp"] = 1500 }, }, } } \startdocument AVAPÆV þýðask {\sc þýðask} 123

You’re invited to our regular online meet-up, this upcoming Wednesday, October 9, 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! 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...
