7. History Ruby and.NET Ruby to.NET Ruby CLR Project RubyCLR All attempted to run Ruby on top of the CLR

8. History CLR 2.0 (.NET 3.0 and 3.5 were still CLR 2.0) No dynamic dispatch Everything had to be compiled Lots of magic, and shims CREDIT: HTTP://WWW.FLICKR.COM/PHOTOS/37341680@N04/4278580062

History alias alias_method_missing method_missing def method_missing(name, *params) alias_method_missing(name, *params) unless name == :Count create_ruby_instance_method(self.class, 'Count') do include 'System.Collections' ldarg_2 call 'static Marshal::ToClrObject(VALUE)' call 'ArrayList::get_Count()' call 'static Marshal::ToRubyNumber(Int32)' ret end self.Count end

10. History CLR 4.0 Dynamic keyword (C#) Calculator calc = GetCalculator(); int sum = calc.Add(1, 3); var calc = GetCalculator(); int sum = calc.Add(1, 3); object calc = GetCalculator(); Type calcType = calc.GetType(); object res = calcType.InvokeMember("Add", BindingFlags.InvokeMethod, null, new object[] { 10, 20 }); int sum = Convert.ToInt32(res); dynamic calc = GetCalculator(); int sum = calc.Add(1, 3);

11. History Dynamic Keyword Calculator calc = GetCalculator(); int sum = calc.Add(1, 3);

12. History Dynamic Keyword var calc = GetCalculator(); int sum = calc.Add(1, 3);

13. History Dynamic Keyword object calc = GetCalculator(); Type calcType = calc.GetType(); object res = calcType.InvokeMember("Add", BindingFlags.InvokeMethod, null, new object[] { 10, 20 }); int sum = Convert.ToInt32(res);

14. History Dynamic Keyword dynamic calc = GetCalculator(); int sum = calc.Add(1, 3);

15. History DLR Introduced in 2007 Set of libraries to assist language developers Still runs on the CLI, and can access the CLR Standardizes the implementation of dynamic languages on the CLI/CLR

16. History IronRuby John Lam hired by Microsoft in 2006 Announced in 2007 at MIX7 Goal to make Ruby a first-class citizen Completely rewritten to take advantage of the DLR

17. History DLR Dynamic Language Runtime (DLR) Common Language Runtime (CLR) Common Hosting Model Runtime Language Implementation
