Really simple resque-pool plugin

Guardfile

require "guard/compat/plugin"

module ::Guard
  class ResqueGuard < Plugin
    def start
      puts "Starting Resque"
      @pid = spawn("bin/resque-pool --hot-swap")
      Process.detach(@pid)
    end

    def reload
      puts "Reloading Resque"
      start
    end

    def stop
      puts "Stopping resque"
      Process.kill("TERM", @pid)
    end

    def run_all
      reload
    end

    def run_on_modifications(paths)
      return false if paths.empty?
      reload
    end

    alias_method :run_on_additions, :run_on_modifications
    alias_method :run_on_removals, :run_on_modifications
  end
end

guard :resque_guard do
  watch(%r{^lib/(.+)\.rb$})
  watch(%r{^app/(.+)\.rb$})
end

Requires resque-pool to be tracked from master, due to use of the new --hot-swap option.
