Git post-checkout and post-commit scripts to ( trigger | stop ) a hcl timer when ( switching branches | committing )

post-checkout

#!/usr/bin/env ruby
# encoding: utf-8

# Git post-checkout script to trigger hcl.
# To be put in .git/hooks/post-checkout and made executable.

# Misc. enhancement ideas :
#   automatically map git branches to hcl tasks, storing data in ~/.hcl-git.yml
#   prompt for input w/ readline & autocomplete hcl aliases 
#   create complementary post-commit script asking wether to stop timer or not
