SetOfRanges

SetOfRanges::Set is a simple gem that inherits from Set and allows Range instances as values. It behaves like Set except that the add method attempts to merge adjacent and overlapping ranges. It was designed for use with integer values. Insertion of new range values is proportional to the number of existing values in the set.

Add this line to your application's Gemfile:

gem 'set_of_ranges'

And then execute:

$ bundle

Or install it yourself as:

$ gem install set_of_ranges

require 'set_of_ranges'

set = SetOfRanges::Set.new
set << (5..10)
set << (15..20)
set.to_a #=>  [5..10, 15..20]

set << (2..6)
set.to_a #=>  [2..10, 15..20]

set << (3..9)
set.to_a #=>  [2..10, 15..20]

set << (11...12)
set.to_a #=>  [2..11, 15..20]

set << (12..14)
set.to_a #=>  [2..20]
