Insertions/Deletions summary for a contributor

Laszlo Papp· Oct 29, 2009, 06:44 UTC · lore

Hello,

It would be nice to see summary for a contributor in insertions/deletions lines, changed files regard, in the life of the whole project.

So the output would be the summary of the following output lines: git log --author="Laszlo Papp" --pretty=tformat: --numstat

Can I deal with it, does it make sense, what do you think about it ?

Best Regards, Laszlo Papp

Try piping the output of the command above through:

  perl -ane '
        $add{$F[2]} += $F[0];
        $del{$F[2]} += $F[1];
        END { print "$add{$_} $del{$_} $_\n" foreach sort keys(%add) }
  '

but keep in mind that such a summary is not necessarily a useful value. Modified lines are represented as deletion and add, and you may simply be deleting and adding the same lines over and over again. :)

A more interesting summary is to "git blame" files and count contributor lines. This shows content by that contributor which has survived to the current tree.
