Typst package check

A tool to report common errors in Typst packages.

This tool can be used in three ways:

• typst-package-check check, to check a single package, in the current directory.
• typst-package-check check @preview/NAME:VERSION to check a given package in a clone of the typst/packages repository. This command should be run from the packages sub-directory. In that configuration, imports will be resolved in the local clone of the repository, nothing will be fetched from the network.
• typst-package-check server to start a HTTP server that listen for GitHub webhooks, and run checks when a PR is opened against typst/packages (or any repository with a similar structure).

Using this tool

You can install this tool with Cargo:

cargo install --git https://github.com/typst/package-check.git
cd my-package
typst-package-check check

You can also run it with Nix:

nix run github:typst/package-check -- check

Finally a Docker image is available:

docker run -v .:/data ghcr.io/typst/package-check check

When running with Docker, /data is the directory in which the tool will look for files to check.

Configuring the webhook handler

The following environment variables are used for configuration. They are all mandatory when running the server that handles webhook. .env is supported.

• PACKAGES_DIR, path to a local clone of typst/packages
• GITHUB_APP_IDENTIFIER, the ID of the GitHub app submitting reviews. This app should have the checks:write permission.
• GITHUB_WEBHOOK_SECRET, the secret provided by GitHub when enabling webhook handling.
• GITHUB_PRIVATE_KEY, the private key of the GitHub app, in PEM format. Directly in the environment variable, not a path to an external file. Note that you can (and should probably) use double-quotes in the .env file for multi-line variables.
