In the CVS/SVN world, there are various statistics/metrics tools. E.G., StatCVS, StatSVN. There are others I've seen.

However, I've not seen similar statistics and visualizations for Mercurial(aka hg).

(1) Are there any out there?

(2) If so, what are they?

Thanks.

We just made the project StatHG publicly available. The project had the goal to develop a tool to extract statistical information from a Mercurial repository and build reports about the work done within a group of developers in a similar spirit as StatCVS. Please take a look and see if it fits your needs. If it doesn’t let us know so we can list the requirements on the TODO list. Thanks for any feedback we can get!

  • Pablo, this looks fascinating. Unfortunately, er, you don't have a download link on bitbucket, or a makefile... How do you build this? – Paul Nathan Mar 15 '12 at 21:30
  • Paul, we've added a zip file with the binaries and instructions on how to run the application. The only prerequisite is that you have at least jre 1.6 installed on your machine. – Pablo Azero Mar 16 '12 at 16:26
  • This looks nifty! I was able to generate a html report on OpenJDK version: `java version "1.6.0_23" OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2) OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)` – Paul Nathan Mar 16 '12 at 20:41

Well as an initial tool, there's the churn extension that get's you some basic statistics about repository. For details on how to activate and use it see ChurnExtension on the mercurial wiki.

If you are interested in a specific (group of) changesets and what files the change, then diffstat is also a good help.

Distributed version control systems such as Mercurial are often used in a way that produces a complex history with lots of merges. That makes some of the plots that StatCVS produces such as lines of code against time harder to read.

  • Yeah, it's not as "clean" as the CVS model. Still though, I'd like to be able to do some nice stats such as a detailed churn readout. – Paul Nathan Jul 14 '09 at 17:59
  • @dickon: it's still possible to gather useful stats from dvcs. see gitstat: http://mirror.celinuxforum.org/gitstat/ – Mauricio Scheffer Jul 16 '09 at 00:27

not sure, but your best bet is to ask on the Mercurial mailing list.

Hg is still relatively new so it's "behind" SVN when it comes to tools.
