[IronPython] IronPython and IronRuby interop with IronRuby 0.9

[Michael Foord]

Hello all,

I've played a little bit with IronPython and IronRuby interop with the 
IronRuby 0.9 binaries.

A very basic example works as expected:

IronPython 2.6 Beta 2 (2.6.0.20) on .NET 2.0.50727.4927
Type "help", "copyright", "credits" or "license" for more information.
 >>> import clr
 >>> clr.AddReference('IronRuby')
 >>> from IronRuby import Ruby
 >>>
 >>> engine = Ruby.CreateEngine()
 >>> source = engine.CreateScriptSourceFromString("puts 'Hello from Ruby'")
 >>> scope = engine.CreateScope()
 >>>
 >>> source.Execute(scope)
Hello from Ruby
 >>>


However my attempts to use a Ruby library fails. The same code works 
when executed from ir.exe:

 >>> import clr
 >>> clr.AddReference('IronRuby')
 >>> clr.AddReference('Microsoft.Scripting')
 >>>
 >>> from Microsoft.Scripting import SourceCodeKind
 >>> from IronRuby import Ruby
 >>> engine = Ruby.CreateEngine()
 >>> source = engine.CreateScriptSourceFromString("require 'date'", 
SourceCodeKin
d.Statements)
 >>> scope = engine.CreateScope()
 >>> source.Execute(scope)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
Exception: no such file to load -- date
 >>>

I tried adding a reference to IronRuby.Libraries to the runtime 
associated with the Ruby engine (using runtime.LoadAssembly) but this 
didn't help.

Requiring Ruby modules I've written myself doesn't blow-up but doesn't 
populate the scriptscope they are executed in with anything. Likewise 
calling engine.ExecuteFile('foo.rb') returns an empty ScriptScope.

Any ideas?

All the best,

Michael Foord
