# Update one package directory:
|
||||
# 1. determine the latest upstream version (pkg.sh: latest_version)
|
||||
# 2. build the binary artifact if the matching GitHub release asset is
|
||||
# missing (pkg.sh: build_artifact), otherwise reuse the published one
|
||||
# 3. refresh PKGBUILD (pkgver/pkgrel/sha256sums), test-build it with
|
||||
# makepkg and regenerate .SRCINFO
|
||||
# 4. commit changes back to this repository
|
||||
# 5. push PKGBUILD + .SRCINFO to the AUR
|
||||
#
|
||||
# Requires: GH_TOKEN (GitHub release + repo push), AUR_SSH_PRIVATE_KEY.
|
||||
# Optional: AUR_GIT_NAME / AUR_GIT_EMAIL for the AUR commit identity.
