Can you open a feature request on CodePlex? It's certainly an interesting idea to ponder and I'm leaning towards it but there's lots of details to be gotten right.
Do you know if this needs to work w/ sockets as well? (There's also the question of can we make it work with sockets? :)) There'll be a bunch of places we need to update (nt, socket, file, select, etc...) so I think it'll have to wait until 2.1 instead of coming in a minor update like 2.0.1. -----Original Message----- From: users-boun...@lists.ironpython.com [mailto:users-boun...@lists.ironpython.com] On Behalf Of Michael Foord Sent: Monday, December 15, 2008 1:20 PM To: Discussion of IronPython Subject: Re: [IronPython] Determine the classes/interfaces a Python implements Hi Jeff, Probably the easiest way of doing this is to define a Python function that uses issubtype. You can use this as a delegate from the C# side (warning untested): ScriptScope scope = engine.CreateScope(); ScriptSource imports = engine.CreateScriptSourceFromString("from System import ISomething", SourceCodeKind.Staatements); imports.Execute(scope); ScriptSource source = engine.CreateScriptSourceFromString("lambda x: issubtype(x, ISomething)", SourceCodeKind.Expression); Func<object, bool> Implements = (scope)source.Execute(scope); bool result = Implements(some_object); Note that issubtype will barf if you give it anything other than a type, so it may make more sense to define a function with exception handling and pull it out of the scope instead.
