# Example consuming workflow. Drop this in a WoW interface repo (e.g. GlueXML)
# at .gitea/workflows/release.yml. Pushing a tag like `v1.0.0` builds the MPQ
# and attaches it to a matching Gitea release.
#
# Requires: Actions enabled on the repo, and a runner advertising `ubuntu-latest`
# with Docker available.
#
# NOTE on octowow.st: the instance is served under the /git subpath, but Gitea
# generates URLs without it, which breaks actions/checkout and `uses:` action
# resolution. So this workflow avoids both: it clones manually against the
# correct base and runs the packager via `docker build` + `docker cp` (bind
# mounts don't work either — the inner docker uses the host daemon). Once the
# server's ROOT_URL is fixed, this can be simplified to actions/checkout +
# `uses: paste/mpq-packager@v1`.
