Abbreviate IRB Method Completion (.irbrc)

#
# This monkeypatch will tell IRB completion to ignore methods that also
# happen to be in the "Object" class as most of the time I don't care
# about these. This hack only steps in when you've entered something like
# "foo." or "Foo." or "Foo::", otherwise you'll be working with the
# full list of methods, including the ones from Object. k?
#

Readline.completion_proc = proc do |input|
  IRB::InputCompletor::CompletionProc.call(input).reject do |o|
    o == nil or (input =~ /(\.|::)$/ and Object.methods.include?(o[/[^\.:]*$/]))
  end
end
