[IronPython] Scripting an unmanaged app with IronPython?
I have an unmanaged app written in C++ / MFC that I'd like to script in some capacity with IronPython. I can see perhaps three broad approaches to doing this: 1. Somehow hosting IP within the app. This would be the ideal, but I don't know if it's possible. It's clear that I would need to create some wrappers that mediate between managed and unmanaged code (i.e., expose functionality as CLR objects). But on top of that I'd need to host IP in the process. I have Michael F.'s excellent IronPython in Action and have been reading a little bit about embedding the engine, but it starts with the premise that the hosting app is itself managed. 2. Create a new managed app that would have access to the wrappers as in #1 and embed IP in that. I think this is definitely possible, but it would have limitations that #1 would not have (e.g., in #1, the user could still do things from the app's gui) 3. Have a new managed app that runs as a separate process and communicates with the unmanaged app, e.g. like COM. The app currently does not have COM interfaces and working with COM is a major pain. Is there an alternative in the .net world that would be similar but easier to use? Thanks in advance for any guidance y'all can offer.

Is there any reason you wouldn't just do this with CPython? In a past life, I had a lot of success embedding CPython into a C++ / MFC application.

Re: [IronPython] Scripting an unmanaged app with IronPython?
Hi Mike, I did this by creating a C++/CLI DLL that wraps our C++ exported classes/functions for .NET. This way there is no .NET code in our core C++/MFC executable and you get the effect of IP being hosted in the application.
