LaTeX Github Actions CD Pipeline Tectonic

Building LaTeX in Github Actions

This pipeline uses tectonic as the build system for LaTeX. Covered here are:

• Custom fonts
• Pipeline
• Upload generated files as artifacts

Fonts

If we are using custom fonts, we need to make them available first. This means checking them into the repo (or downloading them remotely). In this case I chose storing them as LFS files.

In most Linux systems you can install custom fonts under ~/.fonts.

./fonts/
├── Open_Sans.zip
├── Roboto_Mono.zip
└── install.sh

#!/bin/sh

TARGET=~/.fonts
mkdir -p $TARGET
unzip -o -d "$TARGET/roboto_mono" "./fonts/Roboto_Mono.zip"
unzip -o -d "$TARGET/open_sans" "./fonts/Open_Sans.zip"
