My team is using Mercurial, and I would like to know the relative contributions by each team member. I know that we cannot measure productivity by lines of code, but I would like to see if each person at least contributed something, even if it was overwritten by others later. So, I don't just want to see who is responsible for the current version (a la Mercurial annotate), but to do this recursively through all revisions, ideally with output that can be easily visualized or dumped into a spreadsheet.
Any tips?
There's an extension exactly for this, named churn, it is bundled with Mercurial, but not automatically enabled. You can find more information here: ChurnExtension.
In your mercurial.ini file, to the [extensions] section, add the following:
[extensions] churn=
Then to look at the churn of your repository, just do:
hg churn
This will output something like this (this is for the Noda-Time project):
[C:\Dev\VS.NET\Noda-Time-docs] :hg churn skeet@pobox.com 296444 ************************************************************************************************************* james.keesey@gmail.com 203877 *************************************************************************** James Keesey 80466 ****************************** dmitry.bulavin@gmail.com 25552 ********* Dmitry Bullavin 17657 ****** martinho.fernandes@gmail.com 16325 ****** Dmitry Bulavin 4273 ** james.keesey 2650 * matt.scharley 768 configurator 450 lasse@vkarlsen.no 64 TeamCity@Nordrassil 2
