Re: can git-describe learn first-parent behavior?

This seems like it would be a rather useful feature.  Suppose a
maintenance branch, maint/v1.0, is forked from master, and the branch
point is tagged something like "v1.0-stable".  The next commit on
master is tagged "v2.0-base", indicating that it is the first commit
of the new release.  Suppose two releases are made - a release for
public consumption of version 1.0, and a release for internal testing
from master (currently 2.0), and we want to embed the output of
git-describe into the builds.  If bugs were fixed on 1.0, and then 1.0
was merged into master, it seems perfectly possible to run
git-describe on master, but get the v1.0 tag in the output.

The earlier tag (in terms of depth) wins, yes.
 

Is this just a poor workflow?  Am I using git-describe incorrectly?
Or, does a first-parent option to git-describe seem useful?

Thanks for the input.

If you know you want to describe HEAD based on v2 tags you can use

git describe --match v2\* --tags HEAD

"git describe" does not use the revision walk machinery so that it does
not have the --first-parent option. I'm not sure how useful that is, but
it's easy to implement.
