[IronPython] Embedded IronPython 2.6 Module Name

[Dino Viehland]

I think you now want to do:

	      PythonModule pm = new PythonModule();
            ScriptEngine se = Python.CreateEngine();
            PythonContext pc = (PythonContext) HostingHelpers.GetLanguageContext(se);
            pc.PublishModule("__main__", pm);
	    
  	      var modContext = new ModuleContext(pm, pc);
            
            ScriptScope ss = HostingHelpers.CreateScriptScope(se, modContext.GlobalScope);
            ss.SetVariable("__name__", "__ main__");
            ss.SetVariable("__doc__", "");


The change here is to create a ModuleContext which will let you then get the Scope.

I agree this has gotten worse in 2.6 - I opened a bug a while ago to make working with
modules easier - http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=25190.
