include_with_range?(value) click to toggle source

Extends the default Range#include? to support range comparisons.

(1..5).include?(1..5) # => true
(1..5).include?(2..3) # => true
(1..5).include?(2..6) # => false

The native Range#include? behavior is untouched.

("a".."f").include?("c") # => true
(5..9).include?(11) # => false
# File lib/active_support/core_ext/range/include_range.rb, line 10
def include_with_range?(value)
  if value.is_a?(::Range)
    # 1...10 includes 1..9 but it does not include 1..10.
    operator = exclude_end? && !value.exclude_end? ? :< : :<=
    include_without_range?(value.first) && value.last.send(operator, last)
  else
    include_without_range?(value)
  end
end
overlaps?(other) click to toggle source

Compare two ranges and see if they overlap each other

(1..5).overlaps?(4..6) # => true
(1..5).overlaps?(7..9) # => false
# File lib/active_support/core_ext/range/overlaps.rb, line 5
def overlaps?(other)
  include?(other.first) || other.include?(first)
end
step_with_blockless(*args, &block) click to toggle source
# File lib/active_support/core_ext/range/blockless_step.rb, line 9
def step_with_blockless(*args, &block)
  if block_given?
    step_without_blockless(*args, &block)
  else
    array = []
    step_without_blockless(*args) { |step| array << step }
    array
  end

to_default_s(format = :default)

    formatter.call(first, last)
