• Hello, IronRuby!

History

Ruby and .NET

Ruby to .NET

Ruby CLR Project

RubyCLR

All attempted to run Ruby on top of the CLR

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

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);

HistoryDLR

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

History
