Make git status show if on tag

2013-10-09 Thread bpuzon
Hello Git,
 
I was wondering if a patch that adds the tag information (something like what 
git log --decorate produces) to the git status would be welcome?
 
All the best,
Bartek

Do you mean when you are on a branch that also happens to point at the
same commit found at a tag? Or do you mean when you have detached your
HEAD at a tag (e.g., by doing git checkout v1.0).

In the latter case, git v1.8.3 and later will print the tag name
already.

If the former, I don't have a strong opinion (it is not something I
would find useful, but I can see how others might). If it were not
intrusive, like:

  # On branch master (v1.0)

I don't think anybody would complain. It does involve enumerating all of
the refs to calculate it, which might be noticeable. OTOH, status is
not exactly a lightweight operation already, since it has to refresh the
whole index.

You might also consider just showing git describe output, which will
show a tag if you are on it, but also show your distance to the nearest
tag otherwise.  It is more expensive to calculate, though.

It would slow down git status a little.  I haven't thought carefully
about whether that cost is worth it --- it's hard to know without a
rough patch to try it out. ;-)

So the patch would be welcome, as a way to find out.

Thanks,
Jonathan

I meant the latter. So I will just update git then.
Thank you!
