# tcwlab / semantic-release
#
# semantic-release with Forgejo support via @semantic-release/github.
# Forgejo has a GitHub-compatible API — release creation and tag push
# work directly with these env vars:
#
#   GH_TOKEN        → Forgejo API token (secrets.FORGEJO_TOKEN)
#   GITHUB_URL      → https://<your-forgejo-host>          (e.g. https://forgejo.example.com)
#   GITHUB_API_URL  → https://<your-forgejo-host>/api/v1/  (e.g. https://forgejo.example.com/api/v1/)
#
# Included plugins:
#   @semantic-release/commit-analyzer         → Conventional Commits → SemVer
#   @semantic-release/release-notes-generator → Changelog from commits
#   @semantic-release/github                  → Forgejo release + tag
#   @semantic-release/exec                    → Write version to file
#
# Docker tags: tcwlab/semantic-release:<semrel-version>-<wrapper-semver>
