Swiftcore::Tasks

This little library encapsulates a very simple task queue implementation. Tasks have a priority, and an object that responds to #call.

A TaskList is a set of Task objects that it orders according to priority.

The Tasklist allows running the whole queue of tasks, or running just a single task at a time.

If any Task returns a TaskList, that TaskList gets merged into the parent's list of tasks.

Add this line to your application's Gemfile:

gem 'swiftcore-tasks'

And then execute:

$ bundle

Or install it yourself as:

$ gem install swiftcore-tasks

result_list = []
list = Swiftcore::Tasks::TaskList.new
list << Swiftcore::Tasks::Task.new(4) { result_list << 3 }
list << Swiftcore::Tasks::Task.new(2) do
  sublist = Swiftcore::Tasks::TaskList.new
  sublist << Swiftcore::Tasks::Task.new(3) { result_list << 2 }
  sublist << Swiftcore::Tasks::Task.new(5) { result_list << 5 }
  sublist
end
list << Swiftcore::Tasks::Task.new(1) { result_list << 1 }

list.run
result_list == [1,2,3,5]
