History The DLR Why IronRuby? The Million Dollar Question Rusty Washers Getting IronRuby Additional Resources

Or, how Microsoft learned to stop worrying and love dynamic languages

Compiler that translates Ruby source code into .NET IL (Intermediate Langauage)

Ran Ruby code on the .NET CLR (Common Language Runtime)

Started by Dr. Wayne Kelly and Prof. John Gough of the Queensland University of Technology

Lost relevance around the beginning of 2008

“A high-performance Ruby to .NET bridge that allows seamless integration of CLR and Ruby objects in the same Win32 process.”

Developed by John Lam and Ceasar Larry Runs Ruby code on the .NET Common

Language Runtime Abandoned when John Lam was hired by

Microsoft

“IronRuby is a Open Source implementation of the Ruby programming language for .NET, heavily relying on Microsoft's Dynamic Language Runtime”

Microsoft’s implementation of Ruby John Lam hired as Program Manager Current Program Manager (also for IronPython) is

A common runtime for dynamic languages on the .NET platform

Provides interop among various dynamic languages Use libraries from multiple languages simultaneously

Allows hosting dynamic languages in static .NET assemblies New .NET static type: dynamic

IronRuby IronPython IronScheme ClojureCLR IronJS (JavaScript) Nua (Lua)

JS

What is it good for?

Sometimes, you just ‘gotta interop with “Enterprise” systems written in .NET

SOAP and COM

WCF (Windows Communication Foundation) services

Access to the BCL == Base Class Library

Very extensive, rich set of standard libraries

IronRuby eases the pain

Standardized Packaging System Central Repository for hosting packages Allows installation and management of

multiple versions of a package Allows distribution of binary packages

targeting a specific platform

Ruby Gems 1.3.7 includes my patch to recognize universal-dotnet, universal-dotnet-2.0, and universal-dotnet-4.0 as platforms

Acceptance Testing Cucumber

Unit Testing, BDD style RSpec / Shoulda

Factories instead of Fixtures Factory Girl Machinist

YES!

YES! IronRuby.Rack

Rack adapter for IIS (HttpHandler)

Included in IronRuby source on GitHub

Where does IronRuby fall short?

85.94% pass rate

vs 97.53% for MRI

Latest statistics at http://ironruby.info/ Need RubySpec contributions!

RubySepc helps ALL Ruby implementations!

OpenSSL

Needs .NET implementation

Should not be an issue with .NET crypto APIs

Putting my money where my mouth is

If someone will write the RubySpec specs for OpenSSL, I will implement it for IronRuby

IronRuby doesn’t implement the C API However, equivalent libraries with .NET code

can be created (and packaged as Gems!)

eg. iron-term-ansicolor

▪ My lib for color console output on Windows

Cucumber’s parser, Gherkin, is now Ragel based

Ragel does not target C# or .NET Work-around:

Ragel does target Java

IKVM is Java (the langauge) for .NET

Use IKVM to create a .NET assembly

Still has some issues

IronRuby does not support FFI

FFI = Foreign Function Interface

▪ http://wiki.github.com/ffi/ffi/why-use-ffi

Perhaps could be implemented via p/Invoke?

Crazy thought, or craziest thought?

Mono == An open source, cross-platform, implementation of C# and the CLR that is binary compatible with Microsoft.NET

Most active contributors to IronRuby are ‘Softies, so running on Mono is not a priority

However, running on Mono is something the team would like
