Hehe - well I can fish the contents of the library I required from
engine.Runtime.Globals, which seems right as I'm requiring it in the
global namespace. I'm still surprised the ScriptScope is empty.

Ok, so setting the engine search paths solves the failure to find the

example below I would have expected to see 'd' in the ScriptScope.
c:\Binaries\IronRuby\bin>ipy.exe interop.py
[]
From this code:
import clr
clr.AddReference('IronRuby')
clr.AddReference('Microsoft.Scripting')
from System import Array
paths = [r'C:\Binaries\IronRuby\lib\IronRuby',
r'C:\Binaries\IronRuby\lib\ruby\1.8']
array = Array[str](paths)
source_code = "require 'date'\nd = Date::civil(2003, 4, 8)\n"
from Microsoft.Scripting import SourceCodeKind
from IronRuby import Ruby
engine = Ruby.CreateEngine()
engine.SetSearchPaths(array)
source = engine.CreateScriptSourceFromString(source_code,
SourceCodeKind.Statements)
scope = engine.CreateScope()
source.Execute(scope)
print dir(scope)

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
