\char not working with private unicodes
by Jairo A. del Rio 18 May '21

18 May '21

Hi, list! Following this thread: https://tex.stackexchange.com/questions/596610/how-to-use-luatex-with-large…, I tried to replicate it in ConTeXt. Both LMTX and LMTX fail to display the right symbol and, as it's discussed in the linked page, there's an offset by 14. Is this intentional (in ConTeXt)? A bug? Minimal (non-)working example: %Font available here: https://materialdesignicons.com/ \starttext \definedfont[file:materialdesignicons-webfont.ttf]\char"F1372\relax \stoptext Thanks in advance. Cordially, Jairo

underscore hyphenation and hz
by Pablo Rodriguez 17 May '21

17 May '21

Hans, I’m afraid that underscore hyphenation has issues with font expansion: \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") local shared = { start = 1, length = 1, before = utf.char(0xFE000), after = nil, left = false, right = false, } local all = table.setmetatableindex({ }, function(t,k) return shared end) languages.hyphenators.traditional.installmethod("sha", function(dictionary,word,n) return all end) \stopluacode \definehyphenationfeatures [sha] [characters=all, alternative=sha, righthyphenchar="FE000] \definefontfeature [default] [default] [expansion=quality] \setupalign[hz] \sethyphenationfeatures[sha]% \setuphyphenation[method=traditional]% \starttext \hsize\zeropoint abcde \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk

How can I combine in the footer the chapternumber and the chaptertitle in the footer. This way I can achieve the chaptertitle \setupfootertexts [chapter] [\pagenumber] \starttext \input{tufte} \stoptext The following I achieve this with the chapternumber \setupfootertexts [chapternumber] [\pagenumber] \starttext \input{tufte} \stoptext

Variable OTF font resulting in invalid font due to stack overflow
by Marcel Fabian Krüger 16 May '21

16 May '21

Hi, recently we got an interesting bug report in luaotfload (the original report is at https://github.com/latex3/luaotfload/issues/184) which relates to the ConTeXt fontloader. Take the following ConTeXt example: \starttext \definefontfeature [default:bold] [default] [axis={weight=500}] \definedfont[file:NotoSansCJKsc-VF.otf*default:bold @ 10pt] U+5E2E 帮 \stoptext The font is available at https://github.com/googlefonts/noto-cjk/raw/main/Sans/Variable/OTF/NotoSans…. This compiles correctly, but the CJK glyph do not appear since it's Type2 CharString is invalid. The CFF2 CharStrings of this glyph invokes the rrcurveto operator with 63 arguments, which is allowed in CFF2 where the argument limit is 513, but not allowed in Type2 where the limit is at 48. It would be great if ConTeXt could check for this and insert additional rrcuveto operators when necessary to avoid this issue. Additionally we got a report that inkscape 1.0 seems to be incompatible with the way commmands are passed to it for SVG files. Hendrik Seliger suggested to set f_convert (defined in font-ocl.lua, otfsvg.topdf, line 435) to `formatters["file-open:%s; export-%s:%s; export-do\n"]` when a new inkscape version is detected. (See https://github.com/latex3/luaotfload/issues/183) I wasn't able to reproduce the issue in ConTeXt yet. Best regards, Marcel

Expanding a figure into the second column

16 May '21

I have the following MWE whereby the figure nicely fits the first column. If I now have a picture with more details and want to expand it partially into the second column, it will not work with width=1.5\textwidth , is there a simple way to achieve this? \starttext \startcolumns[n=2] \input{tufte} \placefigure [here] [] {my pic} {\externalfigure [cow] [width=.95\textwidth]} \dorecurse{3}{\input{tufte}} \stopcolumns \stoptext

Issue running ConTeXt from TeX Live 2019 on Alpine Linux 3.12
by Nicola 16 May '21

16 May '21

I'd like to run ConTeXt on Alpine Linux (ultimately, to run it on an iPad with the iSH app). I am currently testing it with Docker. This is what I have done: docker pull econcz/x86-alpine-glibc:ish-import docker run -it econcz/x86-alpine-glibc:ish-import /bin/sh cp /etc/apk/repositories /tmp/repositories cat /etc/os-release ALPINE_VERSION=3.12 # Set accordingly to previous command echo "http://nl.alpinelinux.org/alpine/v${ALPINE_VERSION}/main/" | tee /etc/apk/repositories echo "http://nl.alpinelinux.org/alpine/v${ALPINE_VERSION}/community/" | tee -a /etc/apk/repositories apk update This installs and configures repos for Alpine Linux 3.12. Then, I install TeX Live as follows: apk add texlive-full texlive-xetex texlive-luatex texlive-dev apk add ghostscript ghostscript-fonts ghostscript-dev apk add graphicsmagick graphicsmagick-dev Then, I run `mtxrun --generate`, which exits instantly with the output reported below. However, that is apparently not enough. I still get: $ context Hello-world.tex mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ context --version mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ mtxrun --version mtxrun | ConTeXt TDS Runner Tool 1.32 mtxrun | source path $ mtxrun --script context mtxrun | unknown script 'context.lua' or 'mtx-context.lua' $ luatools --generate mtxrun | unknown script 'base.lua' or 'mtx-base.lua' $ find / -name context.lua /usr/share/texmf-dist/scripts/context/lua/context.lua $ find / -name mtx-context.lua /usr/share/texmf-dist/scripts/context/lua/mtx-context.lua $ find / -name base.lua [Nothing found] $ find / -name mtx-base.lua /usr/share/texmf-dist/scripts/context/lua/mtx-base.lua Anyone running ConTeXt on Alpine?

randomize direction of arrow in metafun
by Thomas A. Schmitz 15 May '21

15 May '21

Hi all, for a slide template, I want to draw colored arrows in a randomized color (from a list of colors). This works (and the code is far too clever for me, I must have copied it somewhere): save mycolor ; color mycolor[] ; mycolor[1] := (0.2, 0.3, 0.4) ; mycolor[2] := (0.6, 0.6, 0.4) ; mycolor[3] := (0.5, 0.8, 0.5) ; so I can write drawarrow p withcolor mycolor[round(uniformdeviate(9))] ; But I also want the direction of the arrow to be random. My first idea was to define a variable that would expand either to "reverse" or the empty string right after drawarrow, but that's where I'm stuck. Anyone has an idea how to achieve this? (It's probably somewhere in the source, but I can't find it.) And is the method of defining the random color OK, or could this also be improved. Thanks, and all best Thomas
