# ============================================================================
# Publish kuhy's three Flutter apps to the AUR, hands-off.
#
# Run this once AUR registration is back. It:
#   1. Waits for https://aur.archlinux.org/register to stop returning 503,
#      then opens it in a browser and prints the SSH key to paste.
#      (Signup is the ONLY manual step: it needs an email confirmation, and
#      creating accounts is not something this script will do for you.)
#   2. Waits for `ssh aur@aur.archlinux.org` to authenticate.
#   3. From there, fully unattended, for each package:
#        newest release tag -> pkgver -> updpkgsums -> makepkg -C -> namcap
#        -> pacman -U -> launch check -> .SRCINFO -> clone AUR repo
#        -> commit -> push.
#
# Every package is BUILT, INSTALLED and LAUNCHED before it is pushed, so a
# broken package cannot reach the AUR. A package that fails any gate is
# skipped and reported; the others still publish.
#
# Idempotent and resumable: re-running skips work that is already done, and
# an already-published package is updated rather than duplicated.

Options:
  --skip-wait        Assume the account + SSH key already work; go straight
                     to building and publishing.
  --dry-run          Do everything except the final 'git push' to the AUR.
  --only NAME        Publish just one package (todo-flutter, habit-stack,
                     diet-guard-app).
  --poll SECONDS     How often to re-check /register (default: $POLL_SECONDS).
  -h, --help         Show this help.
