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\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)
