Subject: [PATCH 05/10] www_coderepo: an alternative to cgit
Date: Tue, 4 Oct 2022 19:12:35 +0000 [thread overview]
Message-ID: <20221004191240.1056304-6-e@80x24.org> (raw)
In-Reply-To: <20221004191240.1056304-1-e@80x24.org>
This will allow it to easily map a single coderepo to multiple
inboxes (or multiple coderepos to any number of inboxes).
For now, this is just a summary, but $REPO/$OID/s/ support
will be added, along with archive downloads.
Indexing of coderepos will probably be supported via -extindex,
only.
