If I define a class within a class, like this:

class A:
    class B:
    def foo(self):

The class browser shows that A contains foo, but it doesn't show B at all.

Confirmed on trunk and py3k.

The class browser relies on the pyclbr module to scan the code. This
module doesn't support classes within classes. Both pyclbr and IDLE's
class browser need to be modified.

The attached patch adds support for nested objects in pyclbr and also in

I have yet to find an optimal way to test this on test_pyclbr (I did
some things here, none very nice), so you will notice tests are missing
on this patch.

I've removed the previous patch from here and attached an updated one on

Class Browser is now a module browser as it includes functions not in classes. I guess pyclbr does this. Enhancing this for current versions would require adding a private copy of enhanced pyclbr to idlelib.

I believe the patch for #6691 will also add detection of nested functions.  If  so, the IDLE patch must also make use of that new information.

If the patch for #6691 is only applied to 3.7, I want to put a temporary copy of the revised pyclbr in 3.6 idlelib, perhaps as _pyclbr, and change the 3.6 import accordingly.

I created issue 30881 to add docstrings to to make creating user tests easier.
