After redefining ~ via \def it remains \protected in an \edef, although \show does not say so ``` \starttext \def~{Z} \show~ \edef\foo{~} \show\foo \stoptext ``` Tested 2025/08/02 with ConTeXt ver: 2025.07.21 11:50 LMTX fmt: 2025.7.31 int: english/english from TeXLive2025.

Hi Mikael, Thanks for your suggestion. Unfortunately, both problems still persist. Regarding #2, I'm really curious why the scoping in framedtext doesn't work with \bgroup … \egroup. Forcing a \highlight with \directfontsetup (SomeSystemFont scaled at etc.), however works, but seems a bit brute force. :-( > On Aug 6, 2025, at 17:05, ntg-context-request(a)ntg.nl wrote: > >> 1) The font now (= current version) appears to be larger, causing some undesired line breaks and overfull boxes. >> >> 2) Some elements prevent local font size switching!? >> >> \defineframedtext >> [LabelBox] >> [ >> frame=on, >> bottomframe=off, >> style=\ssx, >> inner={\setupchemical[style=sans]}, >> ] >> >> \ssa So big >> >> \startLabelBox >> \bgroup >> \tfa Title in big letters is still small >> \egroup >> \stopLabelBox >> >> Any hints of how to get some backward compatibility (other than downgrading)? >> >> Thank you! >> >> > > not so long ago, ConTeXt started defaulting to compact fonts.

Preserving Stanza Integrity
by Michael Guravage 07 Aug '25

07 Aug '25

Hi, I'm using code from the last example on *Automatically Centering Verse* from the wiki's verse page <https://wiki.contextgarden.net/Text_blocks/Environments/Verse>. I understand that, to discern its longest line, a poem has to be considered in its entirety. My question is, is there a way to horizontally center a left-aligned block while also ensuring that stanzas aren't split over page boundaries? The MWE uses the text from het Wilhelmus. At the bottom of the first page the fourth couplet is the first to split over two pages. Any sugestions would be much appreciated. -- With kind regards, Michael

Did the font size mechanism change??
by Benjamin Buchmuller 06 Aug '25

06 Aug '25

Hi list, Here is an issue that I should have discovered earlier, but didn't. Probably out of fear that issues as the following would arise. I recently updated from: ["stamp"]="2024.06.21 23:45", ["version"]=0x1.547ae147ae148p+0, to: ["stamp"]="2025.07.27 21:43", ["version"]=0x1.547ae147ae148p+0, My documents define a typescript with: \starttypescript[MyFont] \definetypeface[MyFont][rm][serif][pagella][default] \definetypeface[MyFont][ss][sans][heros][default] \definetypeface[MyFont][tt][mono][modern][default][rscale=1.075] \definetypeface[MyFont][mm][math][pagella][default] \stoptypescript \setupbodyfont [MyFont, 10pt] The following inconveniences arise: 1) The font now (= current version) appears to be larger, causing some undesired line breaks and overfull boxes. 2) Some elements prevent local font size switching!? \defineframedtext [LabelBox] [ frame=on, bottomframe=off, style=\ssx, inner={\setupchemical[style=sans]}, ] \ssa So big \startLabelBox \bgroup \tfa Title in big letters is still small \egroup \stopLabelBox Any hints of how to get some backward compatibility (other than downgrading)? Thank you! Benjamin

Caption alignment and \startfloatcombination
by Florent Michel 05 Aug '25

05 Aug '25

Hi, I came across a (to me) surprising behaviour with captions and \startfloatcombination ... \stopfloatcombination, in the specific case where I set `title` for the combination but not for any sub-figure. If the last sub-figure has a number, the main caption is justified, as I would expect. However, if no subfigure has a number, the caption appears to be centred instead. Simple example demonstrating the issue (adapted from one of the wiki examples; see https://wiki.contextgarden.net/Document_layout_and_layers/Floating_objects) \useMPlibrary [dum] %% sample images \starttext \startplacefigure[title=blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah] \startfloatcombination [nx=2, ny=1] \startplacefigure [number=no] \externalfigure \stopplacefigure \startplacefigure [number=no] \externalfigure \stopplacefigure \stopfloatcombination \stopplacefigure \stoptext Using the version of ConTeXt on my system (LMTX 2025.07.27 21:43 on a 64-bits Linux system), in the example the caption is centered instead of justified. (It is justified, as I would expect, if I delete the second `number=no` or if I set `title` for the second subfigure.) Am I using \startfloatcombination ... \stopfloatcombination incorrectly? Cheers, Florent

sidefloat sorrows

Also with CGJ I found a few problems with marginfloats: – on left pages, they use only half of the margin (PDF*: p.4) – there are some unnecessary page breaks introduced (PDF*: p.2/3) – in CGJ, some captions disappeared (also from numbering), while the images were placed; couldn’t reproduce in a MWE – I didn’t try to solve the caption issues in the example.

It uses random numbers, i.e. it doesn’t show every problem every time. One example is attached. – There are empty pages between chapters (PDF*: p.4 & 13). – Sometimes, the order of chapters gets changed, non-col chapters get postponed or split. (PDF*: ch.2 start on p.5, then follow ch.3 & 4, ch.2 ends on p-14) With CGJ, I tried to place anything on the empty pages in vain, using layers and postponing.

\setuplayout with instances
by Henning Hraban Ramm 02 Aug '25

02 Aug '25

\setuplayout[Instance][Settings] takes only 1 instance, while other similar commands take a list. IMO it would make sense to have a list here (while working at CGJ that uses 4 named layouts). At least the error message could be more understandable – something like "only one value allowed, not a list" instead of "missing number". Hraban

testing language tagging?
by Pablo Rodriguez 01 Aug '25

01 Aug '25

Hi Hans, I did some basic testing with language tagging and but I’m afraid even `agr` still gives `agr` (not `grc`). Is language tagging still to be finished? BTW, is there any way to know which commands have language tagging (a `language` key enabled? Just for the record, my testing sample was: \setuptagging[state=start] \setupstructure[state=start] \setupbackend [format=pdf/ua-2] \starttext \startparagraph \doloopoverlist{agr, ua, deo, farsi, cn, kr, gr, es-la, mo} {\setuphighlight[whatever][language=\recursestring] \highlight[whatever] {testing language: \currentlanguage}} \stopparagraph \doloopoverlist{agr, ua, deo, farsi, cn, kr, gr, es-la, mo} {\startblockquote[\recursestring] \dorecurse{3}{\startparagraph testing language: \currentlanguage \stopparagraph} \stopblockquote} \stoptext Many thanks for your help, Pablo
