# You will have to install the git gem for this to work:
#   gem install git
#
# Name this file 'post-commit' and drop it in the directory '.git/hooks'  in
# any repository that you want to log. Make sure the file is executable. You
# can also add this to your git templates, which will put it in every new
# repository or to existing repositories by re-running git init.  
# 
# A commit message in the log should look this this:
#   2013-07-26-11-25-55 [repository:branch] First line of commit message

require "git"

log_file = "/home/lmullen/todo/time-use.txt"
repo = Git.open(Dir.pwd)
repo_name = Dir.pwd[%r{[\.\-\w]+$}]                       # top directory
date = repo.log.first.date.strftime("%Y-%m-%d-%H-%M-%S")  # format date
message = repo.log.first.message.lines.first.strip        # just first line
branch = repo.log.first.name
File.open(log_file, "a") do |log|                        
  log.puts "#{date} [#{repo_name}:#{branch}] #{message}"  
end

Does this work for you still? I'm having some issues getting it to work. This is super cool, would love to get it implemented if you have a second.

Works for me. But make sure you make the file executable.

chmod +x post-commit

You can also put some puts in the script to test if it is working. See my fork.
