Thanks to some help from William Reade, this code *seems* to work fine.
I need to try it from Silverlight and check the Python code it contains
is able to import:
using System;
using System.Collections.Generic;
using System.Text;
using IronPython.Hosting;
using IronPython.Runtime;
using IronPython.Runtime.Types;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using Microsoft.Scripting.Runtime;
namespace ExecutePython
{
public class ExecutePython
{
static string code = @"
class Foo(object):
attribute = 'weeeee'
";
public static Scope CreateModule(CodeContext context)
{
PythonContext python = PythonContext.GetContext(context);
PythonDictionary globals = new PythonDictionary();
globals["__name__"] = "AModule";
Scope module = new Scope(globals);
SourceUnit script = python.CreateSnippet(code,
SourceCodeKind.Statements);
script.Execute(module);
return module;
}
}
}
All the best,
Michael
