# Description:
# Github commit link looks for <SHA> and links to that commit for your default
# repo. Eg. "Hey guys check out commit 251a8fb"
#
# Dependencies:
# "githubot": "0.4.x"
#
# Configuration:
# HUBOT_GITHUB_REPO
# The `user/repository` that you want to connect to. example: github/hubot-scripts
# HUBOT_GITHUB_USER
# The `user` that you want to connect to. example: github
# HUBOT_GITHUB_TOKEN
# You can retrieve your github token via:
# curl -i https://api.github.com/authorizations -d '{"scopes":["repo"]}' -u "yourusername"
# Enter your Github password when prompted. When you get a response, look for the "token" value
#
# See the following for more details:
# http://developer.github.com/v3/oauth/#create-a-new-authorization
# https://github.com/iangreenleaf/githubot
# HUBOT_GITHUB_API
# Optional, default is https://api.github.com. Override with
# http[s]://yourdomain.com/api/v3/ for Enterprise installations.
#
# Commands:
# Listens for <SHA>s with at least seven characters:
# <SHA> links to that commit in HUBOT_GITHUB_REPO
# repo@<SHA> links to that commit in HUBOT_GITHUB_USER's repo
# user/repo@<SHA> links to that commit in user/repo
# Unless the string 'commit/' shows up in the line, in which case it
# is ignored.
