This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# String.<=> (from ruby core) --- string <=> other_string -> -1, 0, 1, or nil --- Compares `self` and `other_string`, returning: * -1 if `other_string` is larger. * 0 if the two are equal. * 1 if `other_string` is smaller. * `nil` if the two are incomparable. Examples: 'foo' <=> 'foo' # => 0 'foo' <=> 'food' # => -1 'food' <=> 'foo' # => 1 'FOO' <=> 'foo' # => -1 'foo' <=> 'FOO' # => 1 'foo' <=> 1 # => nil
This is MURDOC! A Ruby documentation browser inspired by Smalltalk-80. It allows you to learn about Ruby by browsing through its class hierarchies, and see any of its methods.
