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,

\read segfaults in lmtx
by Marcel Fabian Krüger 20 May '20

20 May '20

Hi, using \read on any existing file seems to trigger a segfault on lmtx. For example, take the document \starttext \newread\myread \openinputfile\myread{test} \read\myread to \abc \closeinputfile\myread \stoptext where test.tex is any file (It doesn't matter if the file is empty or not). On my system (linux x64, latest lmtx) this results in mtx-context | fatal error: return code: 139 Running the command after "executing runner 'run luametatex format':" directly gives segmentation fault (core dumped) /home/marcel/lmtx-install/tex/texmf-linux-64/bin/luametatex cont-yes.mkiv Tracing this command using valgrind shows ==51536== Conditional jump or move depends on uninitialised value(s) ==51536== at 0x1789A6: ???

Why doesn't \starttext \externalfigure[foo.pdf][width=\pagewidth] \stoptext work? Without [width=\pagewidth] it works.

Re: [NTG-context] Inkscape command line arguments have changed
by Thangalin 19 May '20

19 May '20

As a work around, rename /usr/bin/inkscape to new-inkscape, such as: # mv /usr/bin/inkscape /usr/bin/new-inkscape Then change /usr/bin/inkscape to intercept and replace the command line argument: #!/usr/bin/env bash /usr/bin/new-inkscape \ $(echo "$@" | sed 's/--export-pdf/--export-type=pdf --export-filename/') Then make sure the shell script is executable: chmod +x /usr/bin/inkscape This produces the expected results: graphics > inclusion > checking conversion of 'genealogy-sm', fullname 'images/genealogy-sm.svg', old format 'svg', new format 'pdf', conversion 'default', resolution 'default', arguments '' graphics > inclusion > converting 'genealogy-sm' ('images/genealogy-sm.svg') from 'svg' to 'pdf' graphics > inclusion > new graphic, using hash 'images/m_k_i_v_genealogy-sm.svg.pdf->1->crop->->->default->default->default' Stay safe everybody.

Text for proofing fonts
by Pavneet Arora 19 May '20

19 May '20

Hope all are keeping well. An interesting article about text for proofing fonts, although, regrettably, it is focused on English language only: https://www.typography.com/blog/text-for-proofing-fonts Might be worth a further look to see if they can be included in the distribution to expand our library of such texts. The texts are on github, but no mention of license: https://github.com/hoeflerco/proofs I am adding at least the links to staged wiki changes I am working on. Warm regards. -- Pavneet Arora m: +1 647-406-6843 Waroc Informatik e: pavneet_arora(a)waroc.com
