functional api

gistfile1.rb

# I think having the "functional" api to the rest of the system is the important part, if those functions happen to use objects, thats fine to me.
# in this case we are treating the "object" as a way to partially apply all the private functions to share the same arg

# IMO the only "danger" with using objects in this type of place is that you are going to hesitate if you want to add functions
# which do not use "all_events". In this case I think its probably fine, since "ReconcilesEvents" implies working on the full collection

class ReconcilesEvents
  def self.tasks_that_have_not_ended(all_events)
    new(all_events).unended_tasks
  end
  
  attr_reader :all_events
  
  def initialize(all_events)
    @all_events = all_events
  end
  
  def unended_tasks
    # ....
  end
  
  private
  
  def start_events
    all_events.start_events
  end
  
  def end_events
    all_events.end_events
