git annotate with date option not working?

git annotate with date option not working?

[Chengwei Ding]

hello,

can anyone confirm that this "--date" option is working for git annotate 
cmd.

i tried the same option on blame cmd which seems to be working, but not 
on the annotate which i use git annotate --date=relative or i wrote date 
config variable as blame.date which again work for blame but not 
annotate, but document says it should share same variable.

my env:
ubuntu 11.04 64
git ppa source 1.7.5.2

Regards

"git annotate" is left for backwards compatibility, so it might be
that not all git-blame switches work correctly with it.  

Does "git blame -c --date=relative" work?

I tried 'git annotate --date=relative <onefile>' and it works perfectly here.
git version 1.7.4.1
ubuntu 11.04

It works also well on the git version 1.7.5.3.401.gfb674 (The latest on master)

try again on my machine, give same result when with and without --date. 
haven't tried latest master but did try the 1.7.5.3 official release 
(manual compiled)

This is by design:

The annotate command is a historical artifact, and will remain frozen in
time in terms of output format and features. If you want to use newer
features, use "git blame". If you really need the annotate output format
with newer blame features, use "git blame -c".

Thx Peff, this really helps. So then doc on this cmd is outdated. Have
been used to emacs build-in vc which call annotate (rumor say it will
support git blame), anyway, have switch to other emacs git plugin now.

Thanks

Having said that, this would be really easy to support, and I don't
think would have any negative compatibility consequences, as long as we
don't support blame.date. But I don't think we're breaking anybody
relying on "git annotate --date=whatever" being silently ignored, as
that option has never done anything useful.

The patch would look like this:

Looks obviously good to me.  Chengwei (and anyone else), would you be
interested in moving this forward by adding tests and perhaps
documentation?

Thanks.
