[IronPython] Assemblies loaded by default

[Dino Viehland]

Just FYI but this change reflects a change to the underlying DLR hosting APIs.  Under the new hosting APIs the loaded assemblies and there namespaces are reflected through ScriptEnvironment.Globals ScriptScope (and the Python importer now looks there for things to import).  It used to be that we'd always load those 2 assemblies but we no longer load any to give the host precise control over what assemblies they inject.

Ah, excellent; this helped me to find the source file: src\IronPython\Hosting\PythonCommandLine.cs
It actually loads the assemblies for both "string" and "System.Diagnostics.Debug".

Thanks!

I think this is all the IronPython interepreter loads:


ScriptDomainManager.CurrentManager.LoadAssembly(
typeof(string).Assembly); //mscorlib.dll

ScriptDomainManager.CurrentManager.LoadAssembly(
typeof(System.Diagnostics.Debug).Assembly); //System.dll

When I run IronPython interactively, I automatically get System.dll loaded:

PS f:\IronPython-2.0A8> .\ipy.exe
IronPython 2.0 Alpha (2.0.0.800) on .NET 2.0.50727.1433
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import System
>>> System.DateTime
<type 'DateTime'>
>>>

But when I run an IronPython script through the hosting api, I don't:

C# source contains:
SourceUnit source = PythonEngine.CurrentEngine.CreateScriptSourceFromFile("Class1.py");
IScriptScope m = PythonEngine.CurrentEngine.CreateScope();
PythonEngine.CurrentEngine.Execute(m, source);

Class1.py contains:
import clr
import System
Output is:
IronPython.Runtime.Exceptions.ImportException : No module named System

What do I need to do to my embedding host to make sure it's preloading the same assemblies as the interactive console?
