How can I graph the Lines of Code history for git repo?

Basically I want to get the number of lines-of-code in the repository after each commit. The only (really crappy) ways I have found is to use `git filter-branch` to run `wc -l *`, and a script that runs `git reset --hard` on each commit, then runs `wc -l` To make it a bit clearer, when the tool is run, it would output the lines of code of the very first commit, then the second and so on. This is what I want the tool to output (as an example): ``` me@something:~/$ gitsloc --branch master 10 48 153 450 1734 1542 ``` I've played around with the ruby 'git' library, but the closest I found was using the `.lines()` method on a diff, which seems like it should give the added lines (but does not: it returns 0 when you delete lines for example) ``` require 'rubygems' require 'git' total = 0 g = Git.open(working_dir = '/Users/dbr/Desktop/code_projects/tvdb_api') last = nil g.log.each do |cur| diff = g.diff(last, cur) total = total + diff.lines puts total last = cur end ```
