RangeSet
The RangeSet library provides the ability to do set operations on ranges. It comprises an extension to the Range class and a new RangeSet class. Supported set operations are union, intersection and subtraction. Does not work well with ranges with excluded endpoints.
# union:
(1..4) | (3..6) # => 1..6
(1..2) | (3..4) # => [1..2, 3..4]
# intersection:
(1..2) & (3..4) # => nil
(1..4) & (3..6) # => 3..4
RangeSet.new(2..4, 7..9) & (3..8) # => [3..4, 7..8]
# subtraction:
(2..3) - (1..4) # => nil
(1..4) - (3..5) # => 1..3
(1..6) - (3..4) # => [1..3, 4..6]Source Code
