Subject: [PATCH 10/17] hook: convert 'post-rewrite' hook to config
Date: Fri, 4 Dec 2020 17:49:38 -0800 [thread overview]
Message-ID: <20201205014945.1502660-11-emilyshaffer@google.com> (raw)
In-Reply-To: <20201205014945.1502660-1-emilyshaffer@google.com>
By using 'hook.h' for 'post-rewrite', we simplify hook invocations by
not needing to put together our own 'struct child_process' and we also
learn to run hooks specified in the config as well as the hook dir.
