Listing authors of each file in branch HEAD since given revision

Listing authors of each file in branch HEAD since given revision

[Alexander Gladysh]

Hi, list!

For each file in the head of my current branch I need to get a list of
all people who altered it since given revision. If file was not
changed, it should be not listed.

Something like:

  my/file1.ext user1 user2 user3
  my/file2.ext user1

I also need to be able to get closer view with commit names and
messages for along with author names:

  my/file1.ext
    <hash> user1 commit text1
    <hash> user2 commit text2
    <hash> user3 commit text2

  my/file2.ext
    <hash> user1 commit text1

I believe there should be such tool already, or it should be simple
enough to glue it from existing pieces. Please point me to the right
direction.

Thanks in advance,
Alexander.

You will be able to do something like this easily from the output of

git log --pretty=format:%an --name-only HEAD

Probably just a Perl script which reads the author name, and then attaches 
that author name to all following file names until an empty lines occurs, 
recursively.

No rocket science:

git log --pretty=format:%an --no-merges -r --name-only HEAD~100..HEAD |
perl -lne 'our %i; $_ or $a = 0 or next; ++$a == 1 and $b = $_ and next;
$i{$_}{$b}++; END { print "$_: " . join(", ", keys %{$i{$_}}) for (keys
%i); }'

Sorry for the obfuscation. :-)

I know, but I wanted to give Alexander room to grow ;-)
