hyphenate nothyphenated
by Steffen Wolfrum 01 Jul '21

01 Jul '21

When running this mwe with luatex, the command \- could be used to manually break the line, even though it is set up nothyphenated. When running luametatex the word does not break: \setuppapersize[A10] \showframe \setuphead[chapter][align={nothyphenated}] \starttext \chapter{abc\-def} \stoptext Is this intended? Steffen

Sure, and thet adaot to math mode. They will nto dissppear, it's just that in macros I like more verbose names.

log: use \thinspace instead of \,
by Rik Kabel 30 Jun '21

30 Jun '21

All, Examining recent log files, I see the message suggestion > use \thinspace instead of \, When was this instituted? What does it mean? Has \, been deprecated? For many years it was recommended as a short form of \thinspace, and implementing the replacement would certainly result in much less readable source. -- Rik

15th International ConTeXt Meeting (early bird closes)
by Taco Hoekwater 30 Jun '21

30 Jun '21

Hi all, Just a quick reminder that early bird registration for the ConTeXt meeting 2021 in Bassenge officially ends today. I’ll be a bit lenient about the actual money transfer, but you should fill in the registration form today or at the very last tomorrow, if you want to be eligible for the early bird discount. https://meeting.contextgarden.net/ In other news, there is now an abstracts page with lots of talk topics added by Hans himself. Check that out as well! https://meeting.contextgarden.net/2021/abstracts.shtml Finally: this year for the first time we do have a (small) bursary fund. Applications can be added in the remark fields of the registration page, or by sending a message directly to me. I can't wait to see (some of) you in person in Bassenge! Best wishes, Taco — Taco Hoekwater E: taco(a)bittext.nl genderfluid (all pronouns)

makeups with local setups
by Jan U. Hasecke 29 Jun '21

29 Jun '21

Dear all, how can I use setups in makeups locally? Or do I miss something. In this sample the interlinespace of the coverpage makeup is also used after stopmakeup. Is there a way to define the setups values only locally inside the makeup? Or is it better to use something else? \setupinterlinespace [line=2ex] \startsetups[setups:cover] \setupinterlinespace [line=6ex] \stopsetups \definemakeup [coverpage] [pagestate=start] \setuplayout [coverpage] [setups=setups:cover] \starttext \startmakeup [coverpage] \input lorem \stopmakeup % from here I expect the interlinespace of line=2ex. \input lorem TIA juh

Hi, End of the week so time to wrap up. (1) As follow up on the primt/quote discussions I played a bit with additional font features. We already had a partial case feature but that one is also better. The camelcaser is more an experiment (and example). % \definefontfeature[primes] [primes=yes] % \definefontfeature[uppercasing][uppercasing=yes] % \definefontfeature[lowercasing][lowercasing=yes] % \definefontfeature[camelcasing][camelcasing=yes] \setupbodyfont[dejavu] \starttext \startTEXpage[align={tolerant,stretch},offset=1ex] {\addff{camelcasing} \samplefile{tufte}\par} {\addff{uppercasing} \samplefile{tufte}\par} {\addff{lowercasing} \samplefile{tufte}\par} {\addff{primes} 123'345''\par} \stopTEXpage \stoptext (2) (Pablo:) There is some pogress with facing floats that Thomas will check out for real usage. So, still experimental. (3) Already for some 'mails' I mention playing with modifiers in math. The openup varianst are now a bit more tolerant in the sense that they work for more classes. For a while I hav ebeen wondering about the prescripts and to what extend they should be controlled independent. For instance, we can mess with \Umathsupshiftup and such to get some displacement and it can even be done local, but still ... these are normally kind of font drive. So I decided to add a few more parameters, like \Umathextrasupshift for each of the four possible scripts. For convenience I added \supsubscr, \subsupscr, \supscr, and \subscr commands with an optional argument. Basically we can now control quite a lot also because all defaults can be also influenced with \Umath*variant if needed; I probably need to check again if there are any (traditional tex math) hardwired properties. I know that not all of that is really needed (also because much of tex math is chisseled in stone and not supposed to be controlled although in context i suppose we have a bit more freedom) but it simply fit in the luametatex effort to do so. Of course there might be math fields that need such things (so I might add some more modifiers, also because it's kind of fun to do).

paragraph standing out of the normal layout comsuming the margin

Dear all, the mwe shows my try to define a paragraph that stand out like this: On right pages xxxxxxx xxxxxxx xxxxxx xxxxxx xxxxxxx xxxxxxx On left pages xxxxxxx xxxxxxx xxxxxx xxxxxx xxxxxxx xxxxxxx My try with setups does not work. The textcolor is restored but not the layout. Can I reset to the standard layout with an \after command? Any hints? juh

First line of larger font paragraph on grid
by denis.maier＠unibe.ch 28 Jun '21

28 Jun '21

Hi, I have some text in a larger font where the first line should be on the grid. Therefore, I've tried to adapt the solution from the wiki: https://wiki.contextgarden.net/Grid_typesetting#Placing_titles_on_the_grid The interesting thing is that the section command indeed places the first line on the grid, but using \framed directly does not give the desired results. I must be missing something obvious. Does anyone know a solution ? Thanks for your help, Denis =================================== \setuplayout[grid=yes] \showgrid \definefont [BigFont] [Bold at 20pt] [24pt] \unprotect \unexpanded\def\section_command#1#2{% \framed [ width=\textwidth, frame=off, rulethickness=0pt, offset=0pt, loffset=-0pt, before=, location=top, align=flushleft,]{#2}% } \setuphead [section] [ style={\BigFont}, after=, before={\blank[1*line]}, command=\section_command, ] \protect \defineframed[myframed][ width=\textwidth, frame=off, rulethickness=0pt, offset=0pt, loffset=-0pt, before=, location=top, align=flushleft,]] \starttext \blank[force,3*line,depth] \begingroup \BigFont \myframed{Lorem ipsum dolor sit amet consectetur adipisicing elit Lorem ipsum dolor sit amet consectetur adipisicing elit} \endgroup asdfasdf \page \blank[force,3*line,depth] \startsection [title=Lorem ipsum dolor sit amet consectetur adipisicing elit Lorem ipsum dolor sit amet consectetur adipisicing elit] asdf \stopsection \stoptext =========================================
