This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Integer.< (from ruby core) --- self < other -> true or false --- Returns `true` if the value of `self` is less than that of `other`: 1 < 0 # => false 1 < 1 # => false 1 < 2 # => true 1 < 0.5 # => false 1 < Rational(1, 2) # => false Raises an exception if the comparison cannot be made.
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.
