version-bump.yml

name: Bump marketing version

# Auto-increments the app's marketing version (CFBundleShortVersionString) one
# MINOR per feature that lands on `main`, implementing the two-number scheme:
#   * MARKETING_VERSION  — semver shown to users (0.1.0 -> 0.2.0 -> 0.3.0 ...),
#                          bumped here on every push to main.
#   * CFBundleVersion    — monotonic build number from `git rev-list --count`,
#                          set at build time (project.yml). Untouched here.
#
# The maintainer merges feature branches directly into `main` (no PRs), so each
# such merge is a push to `main` and triggers exactly one minor bump.
#
# Loop guard: the bump commit is pushed with the default GITHUB_TOKEN, and
# GitHub does NOT start new workflow runs for GITHUB_TOKEN pushes, so this can't
# recurse. As belt-and-suspenders we also tag the commit with `[skip ci]` and
# skip the job when the head commit already carries that marker.
