upload

Hi, I uploaded a new version, this time a bit of beta, because of: -- reworked control over callbacks: more restrictive, some protection against overload, better control; as a side effect context can run a bit faster but it depends on the job and features used; if something is not working as expected it might relate to this (easy to fix) -- some preparations for an upgrade of grid snapping, profiling and spacing (mostly related to math in the new columnsets); we're still working on columnsets (side effect of mikael converting some advanced documents to use it) -- overload protection enabled, for the moment only the warnings but at some point we might become more restrictive; keep an eye on messages so that you can see where your styles actually messes with already defined macros or enter the dangerous zone of changing primitives; fwiw: i've been running the highest level of protection already for years now (error mode) .. you can try \enabledirectives [overloadmode=error] at the top of your file to see how badly you behave -- a few fixes here and there (related to mailing list questions and reports); nothing spectacular -- some preparations wrt the new signalling mechanism(s) ... more about that after the meeting -- additional warnings (or abort) in case one runs from tex live and missing or expected files -- we're playing with some potential speedups but given the litle gain they might not make it into the lot eventually (if you run into bottlenecks, lets me know, with examples) if there are unexpected side effects, let me know and i'll fix and upload again Hans ps. i might reintroduce the beta/current updating scheme at some point .. still undecided ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Opening quotation mark
by John Was 15 Jun '25

15 Jun '25

Hello I have found that trep=yes gives me correct closing quotation marks in the commercial font Baskerville MT Pro if I type the simple ' as usual in TeX; but opening quotation marks remain as ` or ``. In XeTeX I could get round this with e.g.: \catcode"0060=\active% 0060 is the position for ` \def`{{\char"2018}}% 2018 is the position for ‘ (opening quote) But this fails in ConTexT. Any idea how to fix this, with or without any \catcode fiddling? (In XeTeX the font works as expected if I just give mapping=tex-text when setting up the font call, but I don't see an obvious version of that in ConTexT.) Best wishes John Waś <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> Virus-free.www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_cam…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Thanks for all your answers. > just don't justify: > > \setuphead[align=flushleft] I realized I did not do my homework so well (I certainly had to get up too early). My \sectionhead parameters were already setup with : align={lohi,flushleft,nothyphenated,verytolerant} Maybe my margins are a bit too tight! > \setuphead[section][align={flushleft,nothyphenated,broad}] > > or > > \setuphead[section][align={normal,nothyphenated,verytolerant,extremestretch}] > Adding extremestretch did the job.

line breaks within *section title
by damien＠thiriet.web4me.fr 14 Jun '25

14 Jun '25

Hi, My presentations are using the luciole font (https://luciole-vision.com/) a font designed for eyed-impaired people and big sizes. It is quite appreciated by my pupils. However, some titles are overboxed. There is certainly a way to force line break and avoid such breaks, but I don't know it (although I attended Hans and Mikael's brilliant speeches about \penalty ). I designed a MWE reproducing this with Latin Modern Sans. \setuppapersize [S3] \setupbodyfont [sans,24pt] \setupalign[nothyphenated] \setuptolerance[verytolerant,stretch] \starttext \startsection[title={Don't be hyphenated, no overfullboxes}] \input ward \stopsection \stoptext Thanks, Damien PS: For those interested in Luciole, my typescripts: %\starttypescript [luciole] % \definefontsynonym [Luciole-Regular] [file:Luciole-Regular] % \definefontsynonym [Luciole-Italic] [file:Luciole-Regular-Italic] % \definefontsynonym [Luciole-BoldItalic] [file:Luciole-Bold-Italic] % \definefontsynonym [Luciole-Bold] [file:Luciole-Bold] %\stoptypescript % %\starttypescript [luciole] % \setups [font:fallback:sans] % \definefontsynonym[Sans] [Luciole-Regular] [features=default] % \definefontsynonym[SansItalic] [Luciole-Italic] [features=default] % \definefontsynonym[SansBoldItalic] [Luciole-BoldItalic] [features=default] % \definefontsynonym[SansBold] [Luciole-Bold] [features=default] %\stoptypescript % %\starttypescript [luciole] % \definetypeface [luciole] [ss] [sans] [luciole] [default] %\stoptypescript % %\usetypescriptfile [luciole] %\setupbodyfont[luciole,sans,24pt]

fake small caps
by Henning Hraban Ramm 12 Jun '25

12 Jun '25

For (OpenType) fonts that don’t have native smallcaps, like IBM Plex, I used to get fake smallcaps with \sc. This still worked in 2024-12. Now it doesn’t, and \setsmallcaps or any of the other options that activate the scaps feature also don’t work, which makes sense. https://wiki.contextgarden.net/Pseudo_Small_Caps looks very MkII. Is there a solution? Hraban

Can ConTeXt output in grayscale?
by Joel 11 Jun '25

11 Jun '25

I have a document with lots of color text, Metapost art, and various images in PDF, JPG, and PNG format. I might have the printer just print in black and white, as it cuts printing costs in half. Is there a way to tell ConTeXt to compile everything so it appears grayscale, so I can better visualize how it would look printed? --Joel
