Subject: [PATCH] describe: fix --no-exact-match
Date: Fri, 21 Jul 2023 15:41:33 +0200 [thread overview]
Message-ID: <4eea7e15-6594-93e2-27b5-3d6e3c0baac6@web.de> (raw)
In-Reply-To: <xmqqo7k9fa5x.fsf@gitster.g>
Since 2c33f75754 (Teach git-describe --exact-match to avoid expensive
tag searches, 2008-02-24) git describe accepts --no-exact-match, but it
does the same as --exact-match, an alias for --candidates=0. That's
because it's defined using OPT_SET_INT with a value of 0, which sets 0
when negated as well.
Let --no-exact-match set the number of candidates to the default value
instead. Users that need a more specific lack of exactitude can specify
their preferred value using --candidates, as before.

Or should we just forbid --no-exact-match?
