Revision 88e21dc7461dca1ebc70d8579bcc9246364511ee authored by Shawn O. Pearce on 01 September 2007, 03:47:01 UTC, committed by Shawn O. Pearce on 01 September 2007, 03:47:01 UTC
Lately I have been doing a lot of calls to `git tag -d` and also to `git tag -v`. In both such cases being able to complete the names of existing tags saves the fingers some typing effort. We now look for the -d or -v option to git-tag in the bash completion support and offer up existing tag names as possible choices for these. When creating a new tag we now also offer bash completion support for the second argument to git-tag (the object to be tagged) as this can often be a specific existing branch name and is not necessarily the current HEAD. If the -f option is being used to recreate an existing tag we now also offer completion support on the existing tag names for the first argument of git-tag, helping to the user to reselect the prior tag name that they are trying to replace.
