include_with_range?(value) Show source

# File activesupport/lib/active_support/core_ext/range/include_range.rb, line 12
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

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

overlaps?(other) Show source

# File activesupport/lib/active_support/core_ext/range/overlaps.rb, line 5
def overlaps?(other)
  cover?(other.first) || other.cover?(first)
end

Compare two ranges and see if they overlap each other

(1..5).overlaps?(4..6) # => true
(1..5).overlaps?(7..9) # => false

to_default_s(format = :default)

Alias for: to_s

to_formatted_s(format = :default) Show source

# File activesupport/lib/active_support/core_ext/range/conversions.rb, line 9
def to_formatted_s(format = :default)
  if formatter = RANGE_FORMATS[format]
    formatter.call(first, last)
  else
    to_default_s
  end
end

Gives a human readable format of the range.

(1..100).to_formatted_s # => "1..100"

Also aliased as: to_s

to_s(format = :default)

Also aliased as: to_default_s
