Hi,

Someone asked me a few days ago about their patches being merged yet
(e.g., how to see their commits in a git tree).
Someone else asked (in general) about commit or author counts.

I pointed the first person to "git log" and/or gitweb.
For the second, there are probably lots of scripts out there
but I didn't find them.  Where are they?

Is this useful?  or it needs fixing?
or you already have better solutions?

example:
git log v2.6.19.. | authorcount -m | less

# this is just the ones with >= 50 Author: lines

Al Viro : 213
Linus Torvalds : 94
Jiri Slaby : 90
Josef Sipek : 79
Gerrit Renker : 77
Adrian Bunk : 67
Andrew Morton : 59
Tejun Heo : 52

I often do `git log --author=Shawn next@{1}..next` to see what
commits of mine Junio has recently merged into git.git since my
last fetch.  Since I'm the only Shawn (with that spelling) that
contributes to git.git this works rather well to show my work.  ;-)

Here's another variant showing the top 20 committers to git.git,
no Perl involved:

  $ git log | grep ^Author | cut -d\< -f1 | sort \
  	| uniq -c | sort -n -r | head -20
  3728 Author: Junio C Hamano 
   842 Author: Linus Torvalds 
   250 Author: Johannes Schindelin 
   217 Author: Jakub Narebski 
   194 Author: Eric Wong 
   166 Author: Petr Baudis 
   150 Author: Paul Mackerras 
   147 Author: Kay Sievers 
    88 Author: Nicolas Pitre 
    77 Author: Rene Scharfe 
    67 Author: Shawn Pearce 
    57 Author: Martin Langhoff 
    53 Author: Fredrik Kuivinen 
    52 Author: Nick Hengeveld 
    52 Author: Matthias Urlichs 
    49 Author: Daniel Barkalow 
    47 Author: Ryan Anderson 
    46 Author: Shawn O. Pearce 
    45 Author: Sergey Vlasov 
    45 Author: Luben Tuikov 

The only issue I have with that is I seem to have two attributions
in git.git: 'Shawn Pearce' and 'Shawn O. Pearce'.  Technically I'm
in the top 10 by commit volume but its not immediately clear because
of the two attributions being used.  Really my only issue here is
why sometimes my middle initial gets used and other times it doesn't.

You can also see the very clear gap between Junio and the rest of the
world.  There's very little dispute about who really codes Git.  :-)

I'm personally suprised at Pasky's ranking: 166 commits!  I did
not realize he had contributed so frequently to git.git itself.

With

Perhaps you are talking about this command?

$ git shortlog -n -s v2.6.19..

```

This is what I've done a few times. For the kernel, I actually find the 
"Signed-off-by:" lines to be more relevant to me (since it shows a 
combination of authorship and maintainership, something that I value a lot 
personally), but I've done statistics on both authors and signers-off )and 
committers, but that mainly just shows who uses git to sync and who does 
not), and I've never written any real scripts for it, I just end up doing 
it with some one-liner shell thing using grep, cut, sort and uniq.

See the --author=<string> option to git log.

Try git shortlog -s.  If you combine the two like:

	git log --author=<blah> | git shortlog -s

then you'll have a commit count for <blah> only.

Yes, thanks, probably something like that....

git version 1.4.3.GIT

Can't open v2.6.19..: No such file or directory at /usr/local/bin/git-shortlog line 99.

The git-shortlog being discussed is the new builtin shortlog,
which has not been released yet.  Try the 'master' branch in git.git.

Note that the builtin shortlog reuses the fine revision walking machinery:

	git shortlog --author=<blah> -n -s

works like a charm.

As Junio pointed out in another mail, "git shortlog -n -s | head -20" is
shorter...

Note that this still holds when doing the technically correct thing:

$ git shortlog -n -s --no-merges

I know and use it myself.  But many people might not have a recent 
enough git version for that.
