Counting changed lines of code over time

Question

Is there any good tool that computes the number of changed lines of code over a certain time period in a mercurial repository? Something along the lines of statsvn would be grea

Answer 1

I needed to do this, and spent quite a bit of time with the hg churn extension and similar solutions.

In the end, I found that what worked best for me was CLOC (Count Lines of Code): http://cloc.sourceforge.net/

You can give it two folders containing two versions of a project, and it will count all of the lines that are the same, modified, added, removed. It recognises multiple languages and itemises code, comments and blank lines.

To use it, I pulled out the two versions of my code from Hg into two parallel folders, and then used cloc --diff --ignore-whitespace
