Add this line to your application's Gemfile:

gem 'sleep_walker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sleep_walker

SleepWalker::Planner.run(crontab: "5 3 2 * *", days: 4)

Easy way of getting convinient hash with date key and unix timestamps as a slots. Always return hash with dates and slots

SleepWalker::Planner.call(crontab: "5 3 2 * *", days: 4)
                    .filter_by(window: 
                        [OpenStruct.new(start_datetime: "2018-09-09", end_datetime: "2018-09-10)]
                     ).to_h

Using call to lazily initialize Planner instance and filter schedule by removing slots from window. Call always return Planner instance.
