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
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
# 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 end
Gives a human readable format of the range.
(1..100).to_formatted_s # => "1..100"
# File lib/active_support/core_ext/range/conversions.rb, line 11 def to_formatted_s(format = :default) if formatter = RANGE_FORMATS[format] formatter.call(first, last) else to_default_s end end
