language-metrics

Generates language stats per version. All the hard work is done by GitHub's linguist gem and libgit2.

Usage

Just call the analyze.rb passing the path to the repository you want to analyze. The output will be a CSV of each tag with date and line count per language.

Note that it ignores tags that look like an alpha/beta release.
