[IronPython] IronPython and IronRuby interop with IronRuby 0.9
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

Re: [IronPython] IronPython and IronRuby interop with IronRuby 0.9
Ok, so setting the engine search paths solves the failure to find the
library, but the ScriptScope is still coming back empty. In the example
below I would have expected to see 'd' in the ScriptScope.
c:\Binaries\IronRuby\binipy.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)

Re: [IronPython] IronPython and IronRuby interop with IronRuby 0.9
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.

print scope.d()
print engine.Runtime.Globals.Date
---
Top-level methods, not local variables, are published in the scope.
Classes and modules are published in Runtime.Globals scope.
And this works too (the value of the last expression is returned):
print engine.Execute('''
require 'date'
Date::civil(2003, 4, 8)
''')
