Hi Martin,
thanks for your response.
Now, to satisfy your curiosity,
I'm playing around with a GUI console for IronPython (with intellisense,
call tips and so on ...).
In order to get the same interactive behaviour as the standard console I
implemented the IConsole
interface and thought it would be great if I could reuse
"DoOneInteractive". Unfortunately, you need
to pass a Frame parameter there. If you create your own Module and Frame
then you have to overwrite
all the methods which implicitly use PythonEngine's private _module and
_frame (and _context) :
"Evaluate", "GetVariable", "SetVariable",... (that's what I've actually
done)
This is in no way a satisfactory and elegant solution.
Furthermore, I wanted to "inject" a simple function
in the interpreter. I've maybe overseen something, but the only way I
found to do it was :
engine.SetVariable(new Function0(module,"functionName", new CallTarget0(
... ) ))
In this case too, you need to have a module.
My suggestion would be to have PythonEngine's contructor accept an
optional Frame as argument:
public PythonEngine(Frame top_frame) {
...
if(top_frame==null) {
_module = new PythonModule("__main__", new Dict());
topFrame = new Frame(_module);
}
else {
topFrame=top_frame;
_module=topFrame.__module__;
}
...
}
public PythonEngine() : this(null) {}
That will solve all the problems above.
By the way, while examining the code of "DoOneInteractive" I discovered
the following at line 322 (I'm referring to Beta 2):
if (context.TrueDivision) {
_module.TrueDivision = true; // shouldn't it be
topFrame.__module__.TrueDivision ?
}
Many thanks for your attention,
Keep this excellent work going,
Nandi
