[PATCH/RFC 0/6] sort tags by date (git tag -l -D)

[Marc-André Lureau]

Hi,

I needed to sort my tags by date, and not only the annotated tags. I
was surprised that git tag didn't know how to do that. May be it could
be handled simply by some shell script. Please tell me :)

Take this patch series easy, it's only a RFC. I had some fun hacking
the code, that's the most important for me. I would be happy to take
comment.

Something I wish I could do is also have a better pretty_print_tag()
to have customized format (or may be it should be in git log instead?)

I tried different approach to deal with light tags, and none was
really good. In the end, I decided to use the "object" base type, and
have a private light_tag type. There might be different solutions to
that. I am happy to discuss them.

regards,

Marc-Andre Lureau (6):
  tag: read signature
  tag: parse the date
  tag: copy parsed buffer unconditionnaly
  object: add one bit to let creation of private types (OBJ_MAX + n)
  builtin-tag: add sort by date -D
  test: add simple sorted tag test

As others have pointed out, there's no sane way to sort

Modulo timezone differences

  git for-each-ref --format="%(taggerdate:raw)%(committerdate:raw) %(refname:short)" refs/tags | sort -n | cut -d\  -f3

For some neat reason only one of the dates is displayed, depending on
the type of object.

(Interestingly, the v0.99 tag in git.git doesn't have a date or
tagger...)

... lightweight tags of blobs or trees.

*sigh*

Also, do not take my shell command to mean that I don't like this
series.  It would be nice to have a porcelain feature for it.
