This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Complex.<=> (from ruby core) --- cmp <=> object -> 0, 1, -1, or nil --- If `cmp`'s imaginary part is zero, and `object` is also a real number (or a Complex number where the imaginary part is zero), compare the real part of `cmp` to object. Otherwise, return nil. Complex(2, 3) <=> Complex(2, 3) #=> nil Complex(2, 3) <=> 1 #=> nil Complex(2) <=> 1 #=> 1 Complex(2) <=> 2 #=> 0 Complex(2) <=> 3 #=> -1
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.
