[Ironruby-core] How to implement a C# interface from Ruby ?

Hello again,
I''m playing around with the idea of using IronRuby to implement plugins
for
a C#-based system (namely, CruiseControl.Net).

I''m having some difficulties trying to figure out what the correct
syntax
for that would be. I''m currently using this to bootstrap the engine:

var reader = new StreamReader("plugin.rb");
var code = reader.ReadToEnd();
reader.Close();

var engine = IronRuby.Ruby.CreateEngine();
engine.Execute(code);

The code inside plugin.rb is trying to implement an existing C# interface:

public interface IDoSomething {
void HelloWorld();
}

I tried:

class Doer
  include IDoSomething

  def hello_world
    puts "hello"
  end
end

but it fails. What would be the correct syntax for a Ruby class to implement
this ?

thanks!

[Ironruby-core] How to implement a C# interface from Ruby ?

Have you tried "def HelloWorld; end" (ie. match the interface method
casing)?

[Ironruby-core] How to implement a C# interface from Ruby ?

You need to call the method from C# to check whether it is actually bound to the
CLR interface implementation. The method will always be callable from Ruby.

[Ironruby-core] How to implement a C# interface from Ruby ?

Ah, me = dummy. You have that interface in C#, and the IronRuby code
you''re hosting can''t see the interface. This should expose all
the types in the current assembly:

engine.Runtime.LoadAssembly(GetType().Assembly);

I''ll have a closer look at the hosting tests, I guess this was probably
in
there already.
