Middleman + Guard

# For a similar requirement, I just wrote myself a little Guardfile like this:

require 'guard/guard'

module ::Guard
  class Middleman < ::Guard::Guard
    def run_all
      system("bundle exec middleman build --clean")
    end

    def run_on_change(paths)
      system("bundle exec middleman build --clean")
    end
  end
end

guard 'middleman' do
  watch(/^source/)
end


# Then I just run guard and let it take over.
