[Ironruby-core] Still plugging away at some simple IronRuby stuff

[Michael Letterle]

IScriptModule is now IScriptScope from what I understand.  I couldn't
figure out how to create or access local or instance variables, but
you can use a global.

I got this:


using System;
using Ruby;
using Ruby.Runtime;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
namespace RubyExample
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            IScriptEngine rubyengine =
IronRuby.GetEngine(IronRuby.CreateRuntime());
            IronRuby.GetExecutionContext(rubyengine.Runtime).GlobalVariables[SymbolTable.StringToId("widget")]
= ".NET";
            rubyengine.Execute(rubyengine.CreateScope(),
rubyengine.CreateScriptSourceFromString("puts 'Ruby and  ' +
$widget.to_s + ' together at last'"));

            Console.ReadKey();


        }
    }
}
