It’s used in the other checks, so this should be OK? Yeah, that is OK, as long as you use it with `case` like check_describe does. Because it's a glob and not a regex, you do not have to worry about the anchoring issue. Or if you mean to do an anchored but more general regex like: ^A-.*[0-9a-f]$ that is OK, too. > > > If that's indeed what we're checking, then an easier check is perhaps: > > > > > > ! grep dirty ... > > > > Good. > > This was copied and pasted from the existing check for describe with a > clean working tree. So this should be changed, too. I do think that makes what we're checking more obvious, so I wouldn't mind seeing the other tests converted to use this. But it may be hard if they are relying on check_describe(). I'm OK with anything that works and is robust. :) -Peff
