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 run git reset --hard on each commit, then ran 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
