french quotation marks
by Henning Hraban Ramm 26 Jul '22

26 Jul '22

Hi, according to my knowledge (and also Wikipedia), French uses « … » as double (\quotation) and ‹ … › as single (\quote) quotation marks. The current setting in ConTeXt however is « … » for both, just with less spacing for \quote. If no francophone user objects I’d suggest to fix this.

Count (and limit) glyphs per line?
by Benjamin Buchmuller 26 Jul '22

26 Jul '22

Dear list, I've been confronted with the following 'intriguing' formatting requirement for a document: " • Type density: Must be no more than 15 characters per linear inch (including characters and spaces). • Line spacing: Must be no more than six lines per vertical inch. " While the line spacing resolves in ConTeXt to \setupinterlinespace[line=\dimexpr(1in / 6)] I was wondering if one can limit "type density" as the number of glyphs per inch in TeX too? I thought, it is more convenient to rephrase this request (for a 7 in textwidth) to limit the number of glyphs per line to 112. (Font must be sans or serif, of course ...) I've tried \setuplayout[width=112\averagecharwidth] which, however, results in ~120–130 characters and spaces per line. Pragmatically, I'm narrowing the text width to empirically match the requirement, but I'm nevertheless curious if there is a Lua/TeX solution to this "problem"? Thank you! Benjamin

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

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 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
