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.

Proposal to update the "Manuals" wiki page
by Garulfo 20 May '20

20 May '20

Hi, I hope you're all doing well. Please, you will find a proposal to update the Manuals page on the wiki: https://wiki.contextgarden.net/ManualsGallery 2 objectives: 1/ to make something more visual, to help the user identify the different documents, their organization, their date of release. 2/ to gather all the updated documents in one place Sources were : - http://www.pragma-ade.com/overview.htm - https://wiki.contextgarden.net/Manuals, and wiki snippets here and there. - https://github.com/hmenke/context-examples/blob/master/GUIDE.md Depending on your comments, and if there is an interest, I would be happy to improve it (correct errors, change document segmentation, better colors choice, additional data such as authors, number of pages). It's mainly built from cvs table + script. Finally, if you approve this update, I can arrange to clean up some pages of the wiki about the manuals. Best,
