# Notifies when mail arrives: one notification per account per batch, naming
# the newest senders and subjects.
#
# Watches the notmuch Xapian directory and, on each commit, asks notmuch what
# changed since the revision it last saw. A commit is NOT the same as new
# mail, since reading and tagging also commit, which is why the revision
# counter does the work rather than a count delta.
#
# This is its own process rather than part of waybar-mail.sh, which already
# has the same arrival edge: waybar owns that process, so a bar restart would
# stop notifications with nothing reporting it.
#
# Usage:
# mail-notify.sh watch forever (what autostart runs)
# mail-notify.sh --once process one tick and exit (what the test drives)

# contain dots, so splitting on the first one yields a notmuch tag matching
# nothing and an account that silently never notifies.

# And this walks lines rather than matching a section body as "everything up
# to the next [". Accounts have folders named like [Gmail]/Bozze, which ends
# the body before its label and makes the account display its raw key.
