This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Hash.compact! (from ruby core) --- hash.compact! -> self or nil --- Returns `self` with all its `nil`-valued entries removed (in place): h = {foo: 0, bar: nil, baz: 2, bat: nil} h.compact! # => {:foo=>0, :baz=>2} Returns `nil` if no entries were removed.
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.
