This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Hash.invert (from ruby core) --- hash.invert -> new_hash --- Returns a new Hash object with the each key-value pair inverted: h = {foo: 0, bar: 1, baz: 2} h1 = h.invert h1 # => {0=>:foo, 1=>:bar, 2=>:baz} Overwrites any repeated new keys: (see [Entry Order](#class-Hash-label-Entry+Order)): h = {foo: 0, bar: 0, baz: 0} h.invert # => {0=>:baz}
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.
