Is there a way to import an embedded python script into IronPython as a python module?

Question

I have an embedded resource in my dll which is a python script. I'd like to make the classes and functions in that resource available to the python engine, so I can execute external .py files (as __main__) which would be able to do something like

import embedded_lib # where embedded_lib is an embedded python script

Is there a way to accomplish this? I was hoping there will be some sort of IronPython.ImportModule('module_name', source) so I've looked through IronPython docs and couldn't find anything, but I'm hoping I'm just bad at looking.. Maybe there is some way to intercept a call to import and load my script that way?

It is possible. You just need to add search paths to ScriptEngine object like this:

var paths = engine.GetSearchPaths();
paths.Add(yourLibsPath); // add directory to search

or

engine.SetSearchPaths(paths);

Then you could use any module in directories, which you add:

import pyFileName # without extension .py

Update OK. If you want to use embedded resource strings like module, you may use this code:

var scope = engine.CreateScope(); // Create ScriptScope to use it like a module
engine.Execute("import clr\n" +
                "clr.AddReference(\"System.Windows.Forms\")\n" +
                "import System.Windows.Forms\n" + 
                "def Hello():\n" +
                "\tSystem.Windows.Forms.MessageBox.Show(\"Hello World!\")", scope); // Execute code from string in scope.

Now you have a ScriptScope object (scope in code) containing all executed functions. And you may insert them into another scope like this:

foreach (var keyValuePair in scope.GetItems())
{
    if(keyValuePair.Value != null)
        anotherScope.SetVariable(keyValuePair.Key, keyValuePair.Value);
}

Or you can execute your scripts right in this ScriptScope:

dynamic executed = engine.ExecuteFile("Filename.py", scope);
executed.SomeFuncInFilename();

And in this script you may use all functions without import:

def SomeFuncInFilename():
    Hello() # uses function from your scope

Oh sorry, you whant to use modules from embedded resource... Then I think you may try to execute your embedded resource modules with engine.Execute(string, ScriptScope) and then use its ScriptScope in another executing scripts or files. Or you can always create a temp file with your resource text and use search paths :)

Update your answer accordingly if you think it is answering the question. Add the code to explain it, if needed..

Seems to be working so far, thanks! (Easier than I thought it'd be!)

Is it possible to really use it as a module (I mean with the import keyword?)
