Subject: [PATCH v2 4/6] refs: add pseudorefs array and iteration functions
Date: Sun, 22 Oct 2023 22:44:30 +0100 [thread overview]
Message-ID: <20231022214432.56325-5-andy.koppe@gmail.com> (raw)
In-Reply-To: <20231022214432.56325-1-andy.koppe@gmail.com>
Define const array 'pseudorefs' with the names of the pseudorefs that
are documented in gitrevisions.1, and add functions for_each_pseudoref()
and refs_for_each_pseudoref() for iterating over them.
The functions process the pseudorefs in the same way as head_ref() and
refs_head_ref() process HEAD, invoking an each_ref_fn callback on each
pseudoref that exists.
This is in preparation for adding pseudorefs to log decorations.
