full_auto_updater.sh

#
# Script to fully automate updating and pull request.
#
# That is, 
#  - Checks out LookML code
#  - Runs updater
#  - if and only if any changes made:
#     - commits
#     - pushes to remote
#     - creates a pull request.
#
# Author: Carl Anderson (carl.anderson@weightwatchers.com)
#
# to run, you will need to set:
# 1) GITHUB_TOKEN
# 2) REMOTE
# 3) source of definitions (in config)

brew install hub

#this is your github access token for hub
GITHUB_TOKEN='xxx'
# alternatively, set GITHUB_USER, GITHUB_PASSWORD
