# Heroku helpers
# Example Usage: hcommand app-name
#

# open a Heroku rails console for an app
hcon() {
  appName=$(ensureHasArg $1)
  heroku run rails console -a $appName
}

# get the config for a Heroku app as shell vars
hconf() {
  appName=$(ensureHasArg $1)
  heroku config -s -a $appName
}

# tail the log of a Heroku app
hlog() {
  appName=$(ensureHasArg $1)
  heroku logs -t -a $appName
}

# run `rake db:migrate` on Heroku app
hmig() {
  appName=$(ensureHasArg $1)
  heroku run rake db:migrate -a $appName
}

# restart a Heroku app
hrestart() {
  appName=$(ensureHasArg $1)
  heroku restart -a $appName
}

# run a rake command on a Heroku app
# Usage: hrake app-name namespace:task
hrake() {
  appName=$(ensureHasArg $1)
  rakeCommand=$2 # rake command can't have spaces in it

  if [ -z "$rakeCommand" ]

  heroku run rake $rakeCommand -a $appName
}

# get the name of the last branch deployed to a Heroku app
# note: you must run this command from your local repo directory of the app.
# this command is useful for when you deploy feature branches that aren't master to 
# your heroku app. This is done with the command syntax: `git push heroku feature_branch:master`
hlastbranch() {
  appName=$(ensureHasArg $1)
