Any way to configure \setuphead to run a setups on the stop command?
by Bruce Horrocks 26 Jul '22

26 Jul '22

If I use \definehead [Chapter] [chapter] and then \setuphead[Chapter][...] I can specify setups to run before and after \startChapter. Is there any way to specify setups that are run before & after \stopChapter? My real problem is that I have a double-sided book with new chapters starting on a right hand page. If an extra left-hand page gets added then that extra page is blank except for the header which continues from the previous chapter. This makes the page look a bit odd and I'd rather the header was blank. I can fix this by ensuring each chapter emits a final page (to ensure the headers on the last text-bearing page of the chapter are shown) and then clearing the header temporarily using: \stopChapter\page\setupheader[state=empty] This works so I wondered if there was a way of adding it to \stopChapter ? I can edit each individual chapter file easily enough so no need to add it as a feature if it's not already available in some way. — Bruce Horrocks Hampshire, UK

overfull lines
by Steffen Wolfrum 22 Jul '22

Hi, the command \version[temporary] shows an overfullrule when lines are set overfull. How does this work also in footnotes? MWE: \setuppapersize[A10] \overfullrule5\points %\version[temporary] \starttext \showframe XXXXXX\footnote{xxxxxxxxxxx} \stoptext Steffen

Hi, The recently added Metafun hexagons seem to be producing octagons instead: \startMPpage fill fullhexagon scaled 100; draw unithexagon scaled 50 withcolor white; \stopMPpage -- Max

Hi all, I wanted to place a figure in a cld. The example in the cld manual does not reveal how to influence bahavior except for the caption. context.placefigure( “caption”, function() context.externalfigure({i}, { width = "\\textwidth" } ) end ) Can anybody enlighten me? Kind regards Willi

no greyscales in MetaFun any more?
by Henning Hraban Ramm 21 Jul '22

21 Jul '22

Hi Hans et al., all my greys are black: % MWE: \startMPpage fill unitsquare scaled 10mm withcolor .5; \stopMPpage % real life example: \startMPpage % grayscale squares for s=5 step 5 until 95: numeric c; c := s/100; fill unitsquare scaled 5mm shifted (0,(s-5)*mm) withcolor c; label.lft(100-s, (0, (s-2.5)*mm)); endfor; \stopMPpage This used to work with previous LMTX versions.

Bug in startalign
by Stefan Haller 21 Jul '22

21 Jul '22

Hi! I (presumably) found a bug in the recent math changes of the latest upload. If a cell of the startalign environment is empty, something internally to the macro seems to be breaking. Minimal example: \starttext \startformula \startalign \NC \NC a \NR \NC b \NC c \NR \stopalign \stopformula \stoptext Error: > tex error > tex error on line 5 in file ./test.tex: Missing number, treated as zero > <to be read again> > \23C>1 > <template> > \math_next_in_eqalign \math_left_of_eqalign \mathbeginclass \csname \??mathendclass \the \numexpr \c_math_eqalign_column -\plusone \relax \endcsname > \startforceddisplaymath \everycr \emptytoks > <to be read again> > a > <line 3.5> Filling the empty cell with e.g. "d" makes it work. Using "\strut" or "\quad" or similar also leads to the same error. Best regards, Stefan Haller

If a Font Has Ligature Glyphs But No Feature?
by Michael Urban 21 Jul '22

21 Jul '22

I downloaded something that purports to be Century Expanded from fontsgeek.com. Although the font has fi and fl ligature glyphs, it does not have a ligature font feature and ConTeXt does not use those glyphs. Aside from purchasing a real font product from Linotype at enormous expense and hoping it is better equipped, is there a way to coerce ConTeXt into using the ligature glyphs for fi and fl?

How to setup a headertext in a doublesided document in a cld?
by Willi Egger 20 Jul '22

20 Jul '22

Hello! I tried to setup a headertext in a context-lua-document. — No problem for the singlesided version, however hoe to pass the info for a double sided version? Unfortunately the cld-mkiv manual contains an example for a singlesided document. It ried context.setupheadertexts({ function() context("\\bf”) context.labeltext(monthname) context("\\hfill”) context(year) end}, {function() context("\\bf”) context.labeltext(monthname) context("\\hfill”) context(year) end}) but this is apparently not the good approach. Does someone of you have experience how to do this correctly? Kind regards Willi
