Hi everyone,

I’m messing around with trying to create ironruby mock (actually  
recorder)  
implementations of various sorts of CLR type features and am struggling  
with  
events.

Is it currently possible to create an implementation of a CLR interface  
that  
contains an event?

For example

using System;

namespace ClassLibrary  
{  
public interface IHaveAnEvent  
{  
event EventHandler MyEvent;  
}  
}

…

class ClassWithEvent  
include ClassLibrary::IHaveAnEvent

def initialize  
@blocks = []  
end

def add\_MyEvent  
??? or something ???  
end  
end

Is this possible or not yet available?

I believe that this should work, but the name would need to be Rubified  
as “add\_my\_event”.

No dice i’m afraid:  
with ‘add\_my\_event’:

Snippets.scripting:0:in `add_MyEvent': undefined method`add\_MyEvent’  
for  
IronRuby.Classes.Object$5:ClassWithEvent (NoMethodError)  
from ClassLibrary:0:in `RegisterEvent’  
from experiment1.rb:90

with ‘add\_MyEvent’:

Snippets.scripting:0:in `add_MyEvent': The method or operation is not implemented. (System::NotImplementedException) from ClassLibrary:0:in`RegisterEvent’  
from experiment1.rb:90

Sorry… I just looked at the source code and events are indeed not  
implemented yet. I promised Tomas I’d try really really hard to finish  
the typegen code this month, so you shouldn’t have to wait too long.
