Have you ever wanted to know who’s the top committer in your company?
In my previous company we etablished the term “CVS King”, a title comparable to “Employee of the month”. The developer with the most cvs commits was the “CVS King of the month”. We determined who was the “CSV King” using commit emails that were sent to all developers on each cvs commit.
Two years ago we switched to Subversion, so now we’re talking about the “Subversion King”. Naturally all this is anything but serious ;)

Anyway, today i programmed a little php script that uses a different approach to determine who is the “Subversion King of the Month”. It’s counting the line delta directly from the svn repository using svnlook. So the developer with the most lines added to the repository (not the most commits) is the number one.
Here’s some example output (names are anonymized):

--- Most productive users for 11/2007 ---
1   usera                6319      42.47%
2   userb                5797      38.96%
3   userc                1990      13.37%
4   userd                 773      05.20%
--- Most active commiters for 11/2007 ---
1   usera                  47         47%
2   userb                  34         34%
3   userc                   4          4%
4   userd                   2          2%
-----------------------------------------

The script reads all commits (revisions) for the current month, counts the line delta (how many lines have been added/removed) and the amount of commits.
You can view the highlighted source here or download the script here. Use it on the command line like that:
php -f /path/to/svn/repository

I know that the number of lines comitted may not be the one and only criteria to measure the productivity of a developer. But its an indicator to start with.
So the question is: Are you the “Subversion King” in your company/project?

P.S.
Again, please, dont take this serious ;)
