This repository contains a script for running fontc_crater (a tool for running the fontc font compiler against a large number of inputs) in a CI environment, and the output of those CI runs.

The actual fontc_crater binary lives in the fontc repo; this repo contains a barebones script for checking out and running the latest version of fontc_crater, as well as collecting the results.

This is not a general purpose tool. It is expected to be running on at most one machine at a time.

To get running:

• clone this repository to the running machine
• on github, generate a personal access token that has write access to googlefonts/fontc_crater.
• save this token to a file named GITHUB_TOKEN at the directory root.
• use a scheduler like cron or launchd to execute run.sh nightly

inputs: The set of inputs that are run are stored in this repo, and specified in run.sh. To change the inputs, add a new inputs file and then modify the FONTC_CRATER_INPUT var in that script.

python dependencies: we manage python dependencies using pip-compile, based on a requirements.in file in the fontc repo. See fontc_crater README in that repository for more details.
