Last active December 14, 2015 07:59

	require 'benchmark'

	class Foo
	def optshash opts={}; [opts[:a], opts[:b]] end

lsegal / main.rb

Created February 28, 2013 07:27

This example shows how Ruby compiles a call using an options hash of only symbol values versus one that contains instantiated objects. Note the call to "core#hash_from_ary" on an internal Array vs. pushing all individual keys and values on the stack to build a new Hash.

	require 'benchmark'

	# The code
	class Foo
	def bar_sym
	run a: :a, b: :b
	end

	def bar_string
	run a: :a, b: 'b'

	end

	class AppendixDirective < YARD::Tags::Directive
	def call
	appendix = AppendixObject.new(handler.namespace, tag.name)
	handler.register_docstring appendix, tag.text
