\defineactivecharacter in LMTX + composing characters
by Hamid,Idris 02 Aug '23

02 Aug '23

Dear gang, It appears that \defineactivecharacter does not work in lmtx: \starttext \defineactivecharacter Ḥ {\d{H}} \defineactivecharacter ḥ {\d{h}} \defineactivecharacter Ṣ {\d{S}} \defineactivecharacter ṣ {\d{s}} \stoptext This should not produce any typeset output but in lmtx it does. Background: The following characters are essential for Arabic transliteration (assuming your email client has the chars): Ṯṯ Ḥḥ Ḫḫ Ḏḏ Šš Ṣṣ Ḍḍ Ṭṭ Ẓẓ Ġġ Āā Īī Ūū ʿ ʾ But most really good fonts don't have them, so we have to compose them. Now there are other methods, e.g, 1) \definecharacter Hbottomdot {\buildtextbottomdot H} but cannot use it without something like \defineactivecharacter (there's no way we're going back to the bad old days of control sequences for accented chars). That is, we need to be able to say something like \definecharacter Ḥ {\buildtextbottomdot H} But this doesn't work. The other method 2) \definefontfeature[default][default][compose=yes] doesn't appear to work either (at least not with, e.g., Minion Pro Opticals). And even when it used to (somewhat) work (often ugly default results) it did not support utf 02BE and 02BF (ʿ ʾ). So we still need something like \defineactivecharacter ʿ {\high{c}} \defineactivecharacter ʾ {\kern.07 em \high{\rotate[rotation=180,location=high]{c}}} or better \definecharacter ʿ {\high{c}} \definecharacter ʾ {\kern.07 em \high{\rotate[rotation=180,location=high]{c}}} The upshot is that we need a general, configurable solution for this kind of situation. And please don't say, "Use a different font!" -) Thank you in advance for any guidance and assistance in this matter.

I had these lines in my header: ``` \setupcaptions[minwidth=0.95\textwidth, way=bychapter, prefixsegments=chapter] ``` In the new context, this seem to apply to all captions, while in the old context, it seems to apply only to those captions that are not specified otherwise.

OT: funny units

WRT to funny units consider this thread (in German): https://ruhrpott.social/@Matze/110812742577889798 Matze wrote: I read the 'as big as a song thrush' as a size and I find that we should set 'song thrush' as a standard unit for 20-22 cm. Text problem: Calculate how many square song thrush amount to a Saarland. (Saarland is the smallest federal country of Germany that is not only a city and often quoted for size comparison.) Magdalena calculated that with a given song thrush size of 20cm, one square song thrush is 400 cm² and a Saarland is about 64,250,000,000 square song thrush. ;) HR

Hi, here are three presentation styles for your amusement: https://codeberg.org/fiee/context-for-president I combined the code of my TUG, FrOSCon and CCCamp talks into kind-of a module. It’s still preliminary, comments are welcome. Thanks for all the help! Hraban

empty line before typebuffer

Yet another issue: \typebuffer always starts with a blank line. Is this a bug, or how can I disable it? Hraban MWE: """ \starttext \startbuffer \samplefile{tufte} \stopbuffer \framedtext{\typebuffer[option=tex]} \stoptext """

caption for moved sidefloat in the margin
by Henning Hraban Ramm 30 Jul '23

30 Jul '23

Hi again, I’m reading through the details manual and set up some figures as sidefloats that are offset to the margin. This works well. Now I’d like to have their captions in the margin, below the figure. If I set location=innermargin, then the caption is beside the image, i.e. somewhere at the edge. If I don’t, I can’t get it to move to the left edge of the image. How can I do that? Hraban """ \useMPlibrary[dum] \setuplayout[ backspace=5cm, width=12cm, ] \definefloat[marginfigure] \setupfloat[marginfigure][ leftmargindistance=-\leftmargintotal, rightmargindistance=-\rightmargintotal, default={inner,none,low,high}, ] \setupcaption[marginfigure][ style={\ss\tfx}, align={flushleft}, width=\leftmarginwidth, %location={innermargin,low}, ] \starttext \showframe \startplacemarginfigure[ location={inner,3*hang}, title={My caption should be flushleft and aligned with the image.}, ] \externalfigure[dummy][width=.66\textwidth] \stopplacemarginfigure \samplefile{lorem} \stoptext """

Hi, I’d like to use a custom buffer ("MyBuffer") to use a custom typing style ("MyCode"). How does that work?

issue with current latest (2023.07.28 20:04)

29 Jul '23

Dear list, trying to generate the format for current latest (2023.07.28 20:04), I get this error message: tex error > tex error on line 280 in file lang-lab.mkxl: Control sequence expected instead of undefined \lang_labels_define_class_indeed {head}{ <macro> \definelabelclass ...ded {\lang_labels_define_class_indeed {#1}{\ifchknumber #2\or \lastchknumber \else \zerocount \fi }\expandafter \noexpand \csn ... <line 3.280> \definelabelclass [head] [0] % titles <empty file> You injected something that confused the parser, maybe by using some Lua call. LuaMetaTeX is from 20230727 (just in case it might be relevant). Could anyone confirm the issue? Many thanks for your help, Pablo

Re: setupexternalfigures and resoĺution
by Benjamin Buchmuller 29 Jul '23

29 Jul '23

This thread about downsampling external images on the fly is a really helpful feature! Thanks, Hraban for sharing the code! I was wondering if it was possible to downscale also raster images embedded in pdf/svg files loaded via \externalfigure? I found a ghostscript solution online (https://stackoverflow.com/questions/9497120/how-to-downsample-images-within…) gs \ -o downsampled.pdf \ -sDEVICE=pdfwrite \ -dDownsampleColorImages=true \ -dDownsampleGrayImages=true \ -dDownsampleMonoImages=true \ -dColorImageResolution=72 \ -dGrayImageResolution=72 \ -dMonoImageResolution=72 \ -dColorImageDownsampleThreshold=1.0 \ -dGrayImageDownsampleThreshold=1.0 \ -dMonoImageDownsampleThreshold=1.0 \ input.pdf Now, I'm wondering how to adapt grph-downsample.lua to do this? I've tried: \setupexternalfigure[ resolution=\Resolution, conversion=lowres.pdf ] And added to grph-downsample.lua local function sample_down_pdf(oldname, newname, resolution) print("DOWNSAMPLE sample_down " .. oldname .. " to " .. newname) -- MkIV: -- local image = img.scan{filename = oldname} -- LMTX: local image = figures.getinfo(oldname,1) image = image.status.private local s = format("gs \ -o \"%s\" \ -sDEVICE=pdfwrite \ -dDownsampleColorImages=true \ -dDownsampleGrayImages=true \ -dDownsampleMonoImages=true \ -dColorImageResolution=%s \ -dGrayImageResolution=%s \ -dMonoImageResolution=%s \ -dColorImageDownsampleThreshold=1.0 \ -dGrayImageDownsampleThreshold=1.0 \ -dMonoImageDownsampleThreshold=1.0 \ \"%s\"", oldname, resolution, resolution, resolution, newname) print("DOWNSAMPLE Conversion: " .. s) os.execute(s) end figures.converters["pdf"]["lowres." .. "pdf"] = sample_down_pdf But I must be missing something as the code doesn't seem to be called. Any suggestions? Thanks! Ben
