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

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

regular online meet-up
by Henning Hraban Ramm 09 Oct '24

09 Oct '24

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...

Adding a line after the TOC
by jbf 08 Oct '24

08 Oct '24

I am struggling with something that might be simple enough, but... The author is insisting that on the TOC page, after all the chapters and their page numbers, I need to add the line (obviously without any page number associated with it): 'All translations are by the author'. I have trie various combinations of \writetolist and \writebetweenlist, and I can get his comment at the beginning of the TOC, but I cannot get it at the end, and perhaps with some vertical space separation from the main list. How can I place it at the end? Here is my simple MWE where at least I can get it at the beginning: \starttochead[title={Contents}] \setcounter [userpage] [7] \setupheader[state=stop] \placecombinedlist[content] \writebetweenlist[chapter]{All translations are by the author!} \stoptochead Julian

separatedlist with header repeating processing csv to table
by juh+ntg-context＠mailbox.org 08 Oct '24

08 Oct '24

Dear all, some years ago I asked about how to process a csv file in a table with repeating headers on following pages, but got no answer. https://www.mail-archive.com/ntg-context@ntg.nl/msg98903.html Now I am again working on this problem. I wonder if there is a better way to process csv files to a table with more flexibility? Or do I simply miss the switch to mark the first row in the csv file as the header that has to repeat? TIA juh

Deactivate (back)links of the bibliography
by Gerion Entrup 08 Oct '24

08 Oct '24

Hi, when typesetting bibliographies, ConTeXt seems to link back to the (first?) citation within the text. A side effect is that the whole reference entry is colored in the link color. Is there a possibility to deactivate the back linking or limit it to the key? This is also relevant, when the bibliography contains additional URLs or DOIs that link to external resources but are not highlighted since all surrounding text is colored in the same way. Here is a MWE: ``` \setupinteraction[state=start, color=red] \startbuffer[testdata] @Book{knuth1, author = {Donald E. Knuth}, title = {TEX and METAFONT. New directions in typesetting}, year = {1979}, publisher = {Addison-Wesley}, } @Article{someother, author = {Some Person and Some Otherperson}, title = {Another title}, year = {1900}, } \stopbuffer \usebtxdataset[main][testdata.buffer] \usebtxdefinitions[aps] \setupbtx[dataset=main] \definebtxrendering[bibrendering][aps][dataset=main] \starttext Knuth developed \TeX \cite[knuth1]. Several persons said something \cite[someother]. \placelistofpublications[bibrendering] \stoptext ``` (The whole bibliography entry is red here.) Gerion

Small issue with \breakhere in math mode
by Otared Kavian 07 Oct '24

07 Oct '24

Hi Hans and Mikael, I found a small issue in math mode with \breakhere. When \breakhere is followed by a brace in the following line, it creates a spurious break line. It can be fixed easily by the user by adding an empty line or issuing a \relax command, but I wanted to let you know. Please see the result of the following minimal example: % begin breakhere-bug.tex \starttext Compare \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula and with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere\relax {\darkred z^2} = x^2 + y^2. \stopformula \stoptext % begin breakhere-bug.tex Best regards: Otared

How to improve appearance of bars in frac, sqrt, etc. on screens?
by Ralph 07 Oct '24

07 Oct '24

Hello, I’m relatively new to ConTeXt (version 2024.05.31, LMTX, standalone) and really enjoy learning it so far, but I have one little problem with the appearance of horizontal bars in math mode. It seems the way ConTeXt displayed horizontal extensible bars in math mode some time ago (as used in \frac, \sqrt, \overbar, ...) was similar to the way LaTeX (PDFLaTeX and LuaLaTeX) and Plain TeX handled this, but it has changed since then. Instead of one bar there are now multiple characters attached to each other. This makes it look more consistent with the font, but unfortunately it doesn’t display well in any PDF viewer I’ve tried (on Linux, so I’ve not tried Adobe Acrobat Reader). The bars look dotted, I guess it’s due to anti-aliasing (the dots disappear when anti-aliasing is disabled, but then of course everything looks pixelated). Two screenshots are attached (different zoom levels in PDF viewer) so that you know what I’m talking about. Source: \setuppapersize[S3] \starttext \startformula \sqrt{a^2 + b^2} = \frac{1000 \cdot c}{1000} \stopformula \stoptext Is there a way to switch to the old bars for documents viewed mainly on screens, or is there any other way to improve their appearance? I couldn’t find any documentation on this, so I would be very thankful if somebody here could help out. Best, Ralph
