# Helper to publish a built rfgrep snap to the Snap Store.
# Usage:
#   scripts/publish_snap.sh <path-to-snap> <channel>
# Example:
#   scripts/publish_snap.sh rfgrep_0.2.1_amd64.snap edge
#   scripts/publish_snap.sh rfgrep_0.2.1_amd64.snap stable
#
# Authentication:
# - Run `snapcraft login` interactively once, OR
# - Provide a login export file path in $SNAPCRAFT_LOGIN_FILE (from `snapcraft export-login`), OR
# - Provide exported credentials via $SNAPCRAFT_STORE_CREDENTIALS and we will pipe it to `snapcraft login --with -`.
