Rails/Angular Pre-Commit Hook

gistfile1.sh

#!/usr/bin/env bash
# 
# Rails/Angular pre commit hook.
#
# This should live in your rails config folder and a symbolic link should be created from .git/hooks/ to this file.  You
# should also set the FRONT_END_PATH/BACK_END_PATH env. variable so the script knows where to pull in the front-end code from.
#
# This pre-commit hook does the following:
# 1. Runs rspec (and fails the commit if any tests fail)
# 2. Runs grunts default task on the Front-End project (which should minify and run karam tests).  Fails the commit if any tests fail.
# 3. Copies the Front-End assets into public directory
# 4. Starts the Selium server and runs protractor tests.  Fails the commit if any tests fail.
# 5. Finally, git add any ./public/* files
