build: Automatically parse version from tag

2026-02-18T07:02:26+00:00

The build will now parse tags so the git tag is now the single source of truth for a version. We do not need to manually maintain the version header. The VERSION file uses git's export-subst feature. When git archive creates a snapshot (e.g. cgit), git substitutes the $Format:...$ placeholder with the output of git describe, embedding the version string directly in the archive. This requires the export-subst attribute to be set for the VERSION file in the repository's .gitattributes. The version is resolved in the following order: - git describe (inside a git repository with tags) - the VERSION file (archives/snapshots) - 0.0.0 (fallback) The build system will warn when it can't set a correct version, such as in a git repo without tags, or an archive without VERSION.
