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.

Hth, Dscho

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 ;-)
