# Git Hook that will copy files into deploy-folder when you push into the master branch!
# remember to make this executable "chmod +x post-receive"

# 1. read STDIN (Format: "from_commit to_commit branch_name")
from, to, branch = ARGF.read.split " "

# 2. Only deploy if master branch was pushed
if (branch =~ /master$/) == nil
        puts "Received branch #{branch}, not deploying."
        exit
end

# 3. Copy files to deploy directory
deploy_to_dir = File.expand_path('../deploy') # Change this to your deploy-folder path
`GIT_WORK_TREE="#{deploy_to_dir}" git checkout -f master`
puts "DEPLOY: master(#{to}) copied to '#{deploy_to_dir}'"

# 4. TODO: Deployment Tasks
# i.e.: Run Puppet Apply, Restart Daemons,etc
