[Swig-user] Renaming enum gives 'not found' error

[Adam N. <a.n...@sh...>]

Hi all,

I've just discovered that an enum value buried in one of the classes I am 
trying to wrap is called None, which conflicts with the Python constant None:

   class MyClass {
     enum Attributes {
       None = 0x00,
       ...
     };
   };

Wrapping the class with SWIG normally produces this code in the .py file:

   None = _modulename.MyClass_None

Which makes Python say:

   SyntaxError: assignment to None

I thought I could get around this by simply renaming that value like so:

   %rename(None2) ns::MyClass::None;

However that produces this in the .py file:

   None2 = _modulename.MyClass_None2

Resulting in:

   AttributeError: 'module' object has no attribute 'MyClass_None2'

It would seem that I want to rename the first None (on the LHS) but not the 
one on the RHS.

Does anyone know how this is achieved?

Many thanks,
Adam.
