Example Rakefile additions for Jekyll task timer and push notifications

Raketimer.rb

# Rake file tricks for timing and notifying task completion


# at the top of the file with other config settings
run_time = Time.now

# quick function to determine diff between passed time and now
def finish_timer(start_time)

  total_sec = "%02d" % (finish_time % 60)
  "#{total_min}:#{total_sec}"

# notify "text", [{:quiet => true, :url => "url to open if using Pushover"}]

  # if :quiet is passed in the options, it won't show growl or Pushover notifications
  quiet = options[:quiet].nil? ? false : options[:quiet]

  # might want to make this $stdout depending on what you're doing w/the output
  $stderr.puts Time.now.strftime('%b %d %H:%M%p') + "-> #{msg}"
  unless quiet
