Subject: [PATCH 2/4] hook: introduce "git hook list"
Date: Wed, 4 Feb 2026 18:51:24 +0200 [thread overview]
Message-ID: <20260204165126.1548805-3-adrian.ratiu@collabora.com> (raw)
In-Reply-To: <20260204165126.1548805-1-adrian.ratiu@collabora.com>
From: Emily Shaffer <emilyshaffer@google•com>
If more than one hook will be run, it may be useful to see a list of
which hooks should be run. At very least, it will be useful for us to
test the semantics of multihooks ourselves.
For now, only list the hooks which will run in the order they will run
in; later, it might be useful to include more information like where the
hooks were configured and whether or not they will run.
