no escaping with scite highlighting any more?
by Henning Hraban Ramm 11 Aug '24

11 Aug '24

Hi, this used to work: """ \usemodule[scite] % the setup doesn’t change the behavior, I think it used to. \setuptyping[TEX][ option=tex, % scite sets "cld" ] \starttext \startTEX[escape=yes] \definemeasure[PageWidth][165mm] /BTEX\hfill{\ss Dimensions}/ETEX \definemeasure[PageHeight][239mm] \definepapersize[DANTE][ /BTEX\hfill{\ss Paper size}/ETEX width=\measure{PageWidth}, height=\measure{PageHeight},] \setuppapersize[DANTE] \stopTEX \stoptext """ Without the scite module, escaping in \startTEX works, but I need the module for some other highlighters. Is there a solution? Hraban

Breakable tcolorbox in ConTeXt
by Florent Michel 11 Aug '24

11 Aug '24

Hi, I am trying to reproduce the behaviour of the tcolorbox LaTeX package, more specifically breakable boxes (as illustrated here: https://tex.stackexchange.com/a/676607/123770) It works nicely out of the box (pun intended) using `\definetextbackground` and drawing the frame with MetaPost, using counters to keep track of whether the current text is at the top, middle, or bottom of the box. However, I'm having issues when one box ends and another starts on the same page (see more details below). From what I understand, the issue is that counters seem to be updated on a page-wide basis, so each MPgraphic ‘sees’ the values of counters at the end of the current page, which may not be right if another box modifies them. Would anyone know how to resolve this? Based on two answer on TeX StackExchange ( https://tex.stackexchange.com/a/486124/123770 , https://tex.stackexchange.com/questions/377234/context-frame-problems/37726…) the following code works well if there is no more than one box per page: ``` \definecounter[pageNumberTop] \definecounter[pageNumberBottom] \startuseMPgraphic{mp:axiomframe} begingroup; for i=1 upto nofmultipars : path p; p := ( llcorner multipars[i] -- lrcorner multipars[i] -- urcorner multipars[i] -- ulcorner multipars[i] -- cycle ) enlarged (EmWidth,EmWidth) ; fill p withcolor boxfillcolor ; % if the current page is the first one covered by the box... if (\pagenumber == \rawcountervalue[pageNumberTop]) : % ... if it is also the last one, the box fits entirely on the page; we thus draw the full frame if \rawcountervalue[pageNumberTop] == \rawcountervalue[pageNumberBottom] : draw p withpen pencircle scaled 2pt withcolor boxlinecolor ; % ... otherwise, don't draw the bottom line else : draw llcorner multipars[i] + (-EmWidth, -EmWidth) -- ulcorner multipars[i] + (-EmWidth, EmWidth) -- urcorner multipars[i] + (EmWidth, EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; fi ; picture pic; pic := textext.ulft("\tfd\symbol[info]"); pic := pic shifted ulcorner multipars[i]; fill bbox pic withcolor white; draw pic; % if the current page is the last one covered by the box, draw the left, bottom, and right lines elseif \pagenumber == \rawcountervalue[pageNumberBottom] : draw ulcorner multipars[i] + (-EmWidth, EmWidth) -- llcorner multipars[i] + (-EmWidth, -EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) -- urcorner multipars[i] + (EmWidth, EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; % if the current page is neither the first one nor the last one, only draw the left and right lines else : draw llcorner multipars[i] - (EmWidth, EmWidth) -- ulcorner multipars[i] + (-EmWidth, EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; draw urcorner multipars[i] + (EmWidth, EmWidth) -- lrcorner multipars[i] + (EmWidth, -EmWidth) withpen pencircle scaled 2pt withcolor boxlinecolor ; fi ; endfor ; setbounds currentpicture to OverlayBox ; endgroup; \stopuseMPgraphic \definetextbackground [theoremFrame] [mp=mp:axiomframe, location=paragraph, backgroundcolor=green, framecolor=red, before={\setcounter[pageNumberTop][\pagenumber]}, after={\setcounter[pageNumberBottom][\pagenumber]}] \definestartstop [ColoredBox] [before={\blank[2em]\starttheoremFrame}, after={\stoptheoremFrame\blank[2em]}] ``` For instance, ``` \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` correctly gives a box split over multiple pages, with the top part of the frame only drawn on the first page and the bottom part only drawn on the last one. It also works correctly when adding `\page` between boxes: ``` \starttext \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox \page \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` However, the following gives an incorrect output: ``` \starttext \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox \startColoredBox \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \input knuth \stopColoredBox ``` On page 3, both frames are fully drawn while the first box is a continuation of the one on the previous page and the second one is the start of a box continuing on the next page. I tried several variations without success; my main issue is that (if I understand correctly) the values of counters are the same for the two boxes on page 3, so that at least one of them will be wrong. If someone has any ideas on how to resolve this, I'd be really grateful! Alternatively, if someone has a solution using Tikz, that would also work - I'd ideally use MetaPost as the tight integration with ConTeXt seems (from my short experience) to make many things easier; but any solution using ConTeXt + a small number of other dependencies is fine. Cheers, Florent

How to allow hyphenation, only for footnotes?
by Joel 10 Aug '24

10 Aug '24

My copy editor urged me to remove all hyphens from the main text of my document. I'm using: \definefontfeature[default][default][expansion=quality,protrusion=quality] \start \setupalign[nothyphenated,tolerant,hz,hanging] (text) \stop The problem is that is messing with footnotes, causing things like URLS to run off the page. How can I permit the hyphenation to appear normally, but only on the footnote text? --Joel

OT: lead chemistry
by Henning Hraban Ramm 08 Aug '24

08 Aug '24

Guido Kühn, a design professor, caricaturist and avid manual typesetter, recently bought an old, empty cabinet for lead fonts. In that, he found a leftover piece of chemistry typesetting, made out of Berthold chemistry letters – nowadays exceptionally rare, since they were smelt down even earlier than other lead type. source with photos: https://mastodon.social/@GuidoKuehn/112922576039332335 https://mastodon.social/@GuidoKuehn/112927659972511919 https://cartoons.guido-kuehn.de/category/druckwerkstatt/

language not working in transliteration?
by Pablo Rodriguez 08 Aug '24

08 Aug '24

Dear list, I have the following sample: \mainlanguage[it] \starttext \usetransliteration[serbian] \definetransliteration [MySerbian] [color=red, language=de, vector={serbian to latin}] \definetransliteration [MySerbianX] [MySerbian] [color=blue] \transliterationexception[serbian to latin] {whatever}{(\currentlanguage): } \starttransliteration[MySerbian]% whatever А \stoptransliteration \transliteration[MySerbianX]{whatever А} \stoptext In both cases, current language is main language (in the sample above, "it" instead of "de"). Am I missing something here? (Sample adapted from lang-tra.mkxl.) Many thanks for your help, Pablo

workflow tool: add to git
by Henning Hraban Ramm 07 Aug '24

07 Aug '24

In case you organize your ConTeXt projects in git repositories: "addtogit.py" is a little script that checks your log (or jlg) file for the local files used and adds them to the git stage. (No automatical commit so that you can check if you want these files.) Leaves out auto-generated files like "m_k_i_v_*". Needs Python and GitPython (pip install gitpython). https://codeberg.org/fiee/context-tools Have fun, Hraban

I have defined a determinant environment like below: \definemathmatrix[determinant] [matrix:bars] [simplecommand=thedeterminant] and I create a determinant like below: \startformula \startdeterminant\NC a_{11} \NC a_{12} \NC a_{13} \NC \cdots \NC a_{1n}\NR \NC a_{21} \NC a_{22} \NC a_{23} \NC \cdots \NC a_{2n}\NR \NC a_{31} \NC a_{32} \NC a_{33} \NC \cdots \NC a_{3n}\NR \multispan{9}{\dotfill}\NR \NC a_{n1} \NC a_{n2} \NC a_{n3} \NC \cdots \NC a_{nn} \NR\stopdeterminant This was working before today but I updated ConTeXt and it has stopped working. The error it gives me now is: tex error > tex error on line 277 in file determinants.tex: You can't use '\Ustopmath' in restricted horizontal mode How can I get it working again? -- Respect, Shiv Shankar Dayal
