Subject: [PATCH 3/5] config: support more cgit directives for project lists
Date: Fri,  5 Apr 2019 20:04:27 +0000	[thread overview]
Message-ID: <20190405200429.16973-4-e@80x24.org> (raw)
In-Reply-To: <20190405200429.16973-1-e@80x24.org>

Hopefully this gets us closer to matching cgit upstream behavior
(which also lacks tests).  We'll still need to support macro
expansion at some point for compatibility...
