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

Ligatures blocking -- why block unspecified ligatures?

(I am trying to block certain ligatures globally, ie. ft,fft,fj,ffj,fk, but fi, ffi, fl, fll are being dealt with in the language goodies file.) Thanks for your help, Denis

Include PDF pages

Hello everybody: My query is as follows: in LaTeX there is the package "pdfpages" (https://www.ctan.org/pkg/pdfpages) that allows pages from a PDF file to be included in a TeX document. Is there a similar procedure that works in ConTeXt? Thanks. M. González.

Happy to announce that invoking ConTeXt from KeenWrite is now possible. Here's a screenshot showing three different PDFs compiled from the same plain text document: https://github.com/DaveJarvis/keenwrite/blob/master/docs/screenshots.md#pdf… Here are the installation instructions for ConTeXt (basically, make sure that the "context" executable can be found in the system PATH): https://github.com/DaveJarvis/keenwrite/blob/master/docs/typesetting.md KeenWrite downloads: https://github.com/DaveJarvis/keenwrite#download Stay safe everyone!
