RCC 2008.2 IronRuby Talk

Writing

I just finished giving my talk on IronRuby at the Richmond Code Camp 2008.2. It was titled “Microsoft and Ruby Sittin’ in a Tree”. I tried to cover a huge number of features in Ruby very quickly and then show off a few Ruby snippets that demonstrate many of its cool features. As usual you probably won’t get a huge amount out of the slides without seeing the accompanying presentation, but you can still go through it if you would like. I have included the source for my demos in the zip as well, and that is probably the more interesting part. It has some basic language primer, which I didn’t get to in the presentation, and it also has some more advanced “showy” demos.

I demonstrate 5 main things in the code samples:

1) A proxy class that allows you to pass an instance of a class to its constructor and then intercept method calls and do something. Just wanted to show how easy it is in Ruby with method_missing.

2) Second it shows off a recorder which lets you call a bunch of methods on a recorder object and then play those calls back against a target object. I wanted to implement this and search online and found an example of Jay Field’s blog. I studied his implementation for mine, so I have to give props.

3) Third I showed off a bit of Meta-Programming which uses class_eval and define_method to create new methods on a class.

4) Fourth I showed off a bit of .net Interop which just displays a form with a field and a button. It shows assigning a block to use as an event handler.

5) Fifth I showed how to consume a WSDL file in Ruby and then call the web service. Then I use REXML to parse the resulting XML and display it in the console. This the only of the five demonstrations that won’t run yet under IronRuby.
