How to define a font with an effect as a font with \definefont
by Gerben Wierda 23 May '20

23 May '20

Wityh this working example: \starttext The quick brown fox jumped over the lazy dog \definefontfeature [effect-widen] [effect={width=.2,delta=0.3}] \definedfont[Sans*widen,effect-widen] The quick brown fox jumped over the lazy dog \stoptext I am puzzling to turn my working \definedfont into a \definefont so I can use that instead. Actually, my setup is Optima with Helvetica used for Cyrillic: \definefallbackfamily [archimate] [ss] [Helvetica] [preset=range:cyrillic, tf=style:light, it=style:lightoblique, bf=style:regular, bi=style:oblique, force=yes, rscale=1.0] \definefontfamily [archimate] [ss] [Optima] \setupbodyfont[archimate] And I would like the effect to work on just the Optima font (which is a bit light for this use) I’ve been trying to work out using \definefont with the effect but have so far failed. Thanks, G

output file name query
by Alan Bowen 23 May '20

23 May '20

In my project, I process a single product file by enabling various modes. What I would like to do is to vary the name of the output PDF file in each instance. So, in processing a file, how does one go directly from prd_filename.tex to myfilename.pdf rather than to prd_filename.pdf—assuming that it is possible? Any tips or pointers to what I should be reading will be greatly appreciated. Alan

List of language-specific hyphenation commands
by Jairo A. del Rio 23 May '20

23 May '20

Hi everybody! I've read about some commands which allow hyphenation according to an specific language in ConTeXt, e.g. \french{word} for French hyphenation in a text the main language of which is Spanish, English, etc. Unlike \language[code], I couldn't find any extensive list of those commands, so where should I find them? Thank you in advance!

Getting width of text to be typeset
by context＠vivaldi.net 23 May '20

23 May '20

Hello, is it possible to get somehow the width of the "material" (box?) of the current line which is "ready" to be typeset? See the case: ---- \starttext some text pqrs % Here I need to get width (or content) of the text from the begin of the current line, % i.e. width of the text "pqrs". % (Depending of the width I will decide what to do later.) \stoptext ---- I am too laical to know how to "inject" TeX workflow or whether to access LuaTeX internals (nodes?) to get the desired information. - Is it possible somehow? Best regards, Lukas

Text to be placed into the free space after columns and end of the page
by context＠vivaldi.net 22 May '20

22 May '20

Hello, suppose the minimal example: ---- \showboxes \starttext \startcolumns[n=2,balance=no,] \input knuth \stopcolumns \vfill abcd \stoptext ---- This produces two page document with columns on the first page and text "abcd" on the second. But - I want the text "abcd" to be placed to the bottom of the same page as columns are (thus I attempted to put \vfill into the code, but it doesn't work), so to get one page document looking like: +------ page width -----+ Column text | (unused) column text | column text | column text | column text | column text | (some vertical space) abcd +----- end of page -----+ - How to achieve this? Best regards, Lukas

Re: [NTG-context] Emoji color fonts not working on LMTX/Context MKIV
by Jairo A. del Rio 21 May '20

21 May '20

I did. It turns out that installing graphicsmagick does the trick (pun intended) for Noto Color Emoji. However, the issue persists for SVG fonts and the same message appears, despite of having cleaned the cache (I've used mtxrun --script cache --erase). Using the code Pablo sent, with EmojiOne Color instead of Twemoji Mozilla, I get the following error messages: LMTX (error): function call [998]: ...mtx/tex/texmf-context/tex/context/base/mkiv/mlib-svg.lua:1471: bad argument #1 to 'gsub' (string expected, got nil) MKIV (outlined emojis, flag emojis not working): fonts > svg conversion > executing runner 'otfsvg': inkscape --export-area-drawing --shell > temp-otf-svg-shape.log fonts > svg conversion > processing 1829 svg containers xml > core > load error: invalid xml file - parsed text (the line below repeated dozens of times) fonts > svg conversion > processing can be going on for a while fonts > svg conversion > processing 1829 pdf results fonts > svg conversion > there are no converted shapes, fix your setup fonts > svg conversion > svg conversion time 4.246 seconds In any event, LMTX prints only black and white emojis.

context --purgeall filename does not delete all temporary files
by Aditya Mahajan 21 May '20

21 May '20

Hi, `context --purgeall filename` behaves differently from `context --purgeall`. `context --purgeall` deletes all files with the name `*-temp-*`. I would have thought that `context --purgeall filename` will delete all files with the name `\jobname-temp-*` but it does not. Is there a way to delete the `\jobname-temp-*` files without requiring an extra `context --purgeall` run? This is needed for deleting extra files by `t-filter` module or deleting extra files generated by automatic EPS to PDF conversion (with figures.cachepaths.prefix="\jobname-temp"), etc. Thanks, Aditya

Emoji color fonts not working on LMTX/Context MKIV
by Jairo A. del Rio 20 May '20

20 May '20

I've tried the following from the manuals and adapted some code to see if it works: 1. \definefontfeature[svg][svg=yes] \definefontsynonym[Emoji][file:emojionecolor-svginot.ttf*default,svg] \definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}] \starttext \symbol[bug] \stoptext The emoji has no color when compiled with LuaTeX. Furthermore, the log includes a lot of lines like the ones below: fonts > svg conversion > executing runner 'otfsvg': inkscape --export-area-drawing --shell > temp-otf-svg-shape.log fonts > svg conversion > processing 1829 svg containers xml > core > load error: invalid xml file - parsed text With LMTX it gives an error about mlib-svg. 2. \definefontfeature[overlay][default][ccmp=yes,colr=yes,dist=yes] \definefontfeature[svg] [default][svg=yes] \definefontfeature[bitmap] [default][sbix=yes] \definefontfeature [colored] [default] [ccmp=yes,dist=yes, colr=yes,svg=yes,sbix=yes] \definefontsynonym[Emoji][file:notocoloremoji*default,colored] \definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}] \starttext \symbol[bug] \stoptext What I get is: fonts > png conversion > processing 3374 png containers sh: 1: gm: not found sh: 1: gm: not found sh: 1: gm: not found sh: 1: gm: not found ... and the same line repeating itself ... close source > level 1, order 3, name '/home/lol/lmtx/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' ! error: (file /usr/share/fonts/truetype/noto/NotoColorEmoji.ttf) (ttf): loca table not found LMTX prints a file without any emoji. Only Twemoji Mozilla and Segoe UI Emoji worked for me, so, what am I doing wrong? I'm working with Ubuntu 20.04 LTS x86_64 and Inkscape 0.92.5 (2060ec1f9f, 2020-04-08) in case it helps. Thank you in advance.
