# .gitea/workflows/version.yml
#
# Reusable Gitea Actions workflow that:
#   - computes the next semantic version from commit-message tokens
#   - writes VERSION.md in the repo root
#   - on the main branch, creates a git tag and a Gitea release when
#     MAJOR, MINOR, or PATCH actually changed
#
# Drop this file in at `.gitea/workflows/version.yml` and edit the two
# values in the `Install semver-ci` step that point at your small-scripts
# repo if they differ from the defaults.
#
# Requirements:
#   - Gitea Actions enabled for the repo
#   - A `GITEA_TOKEN` secret with write access to the repo (used for
#     creating the release). `GITHUB_TOKEN` is also provided automatically
#     by Gitea Actions and is accepted as a fallback.
#   - Commit triggers: put NEW_MAJOR, NEW_MINOR, or NEW_PATCH on a line
#     of its own in a commit message to bump the corresponding part.
