This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Gem::Requirement.to_s (from ruby core) ### Implementation from Object --- obj.to_s -> string --- Returns a string representing *obj*. The default #to_s prints the object's class and an encoding of the object id. As a special case, the top-level object that is the initial execution context of Ruby programs returns ``main''.
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.
