[Ironpython-users] Options for debugger for DLR languages on Mono

[Dino Viehland]

Do you have a using statement for IronPython.Hosting?  If you add that you should
get the extension method showing up on ScriptEngine.

As for tracing the hosting level - can you describe what you mean?  Do you have additional
hosting code written in Python?

I didn't see GetSysModule for some reason in IronPython 2.7....
perhaps a Mono issue, or maybe I'm not importing it correctly?

But I was able to:

IronPython.Hosting.Python.GetSysModule(engine).settrace(trace)
source = engine.CreateScriptSourceFromFile(filename)
source.Compile()
source.Execute(scope)

However, it ended up tracing the hosting level, rather than the source. Is that an IronPython issue? Or user error? Is there another way to inject a trace in an execution?
