This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Hash.values_at (from ruby core) --- hash.values_at(*keys) -> new_array --- Returns a new Array containing values for the given `keys`: h = {foo: 0, bar: 1, baz: 2} h.values_at(:baz, :foo) # => [2, 0] The [default values](#class-Hash-label-Default+Values) are returned for any keys that are not found: h.values_at(:hello, :foo) # => [nil, 0]
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.
