Rake tasks for managing your spork server. Check the Rakefile to bypass loading Rails to run these rake tasks super fast.

Rakefile

#!/usr/bin/env rake
# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

# If certain tasks are called, don't load Rails!
if %w(spork:start spork:restart spork:stop).include?(Rake.application.top_level_tasks.first)
  # Load the rake tasks
  Dir.glob("#{File.expand_path("../lib/tasks", __FILE__)}/*.rake").each { |r| import r }
else
  require File.expand_path('../config/application', __FILE__)
  Concourse::Application.load_tasks
end

spork.rake

# Let's fork spork and put in the background and forget about it.
# You can start|stop|restart spork using this rake task
#
# Examples
#
#   rake spork:start
#   # => starts spork and detaches the process
#
#   rake spork:stop
#   # => kills the spork process based on the pid stored in tmp/spork.pid
#
#   rake spork:restart
#   # => stops then starts spork
