This is a collection of scripts intended to integrate Flathub's backend with its flat-manager instance. It uses the hooks feature of flat-manager, which runs commands at certain points in the upload/build/publish process.
These scripts are specific to Flathub. They aren't intended to be generalizable, but if you're running your own instance of flat-manager you can specify your own set of scripts to do something similar.
All of the hooks are built as the same Rust binary and called using subcommands.
This hook is run during the publish job. It fetches information about the app from the backend and edits the build's commits to match. It updates appstream data, commit subsets, and token type.
