inspect.getmembers() on cppyy.gbl not detecting enums and functions

[cgdae]

inspect.getmembers() does not seem to see C++ functions and enums inside cppyy.gbl. But it does see functions and enums inside a C++ namespace within cppyy.gbl.

The same behaviour occurs with dir().

This is with cppyy.__version__ = 2.3.0

I understand that cppyy is generally lazy about creating things, but given that it seems to be able to enumerate functions and enums in a C++ namespace within cppyy.gbl, i was hoping it would be able to do so for cppyy.gbl itself.

So, is this expected behaviour? Can anything be done to allow detection of enums and functions within cppyy.gbl?

Python code that demonstrates the problem:

import cppyy
import inspect

def show( namespace):
    '''
    Show items in <namespace> whose names do not start with an
    underscore.
    '''
    print( f'{namespace}:')
    for n, v in inspect.getmembers( namespace):
        if not n.startswith( '_'):
            print( f'    {n}={v}')

# Create some C++ functions, enums and a namespace:
cppyy.cppdef('''
        enum { FOO };
        void foo() {}
        namespace N
        {
            enum { BAR };
            void bar() {}
        }
        ''')

show( cppyy.gbl)    # Does not show FOO or foo().
show( cppyy.gbl.N)  # Shows BAR and bar().

# foo() and FOO do exist if we ask for them explicitly:
print( f'cppyy.__version__={cppyy.__version__}')
print( f'cppyy.gbl.foo={cppyy.gbl.FOO}')
print( f'cppyy.gbl.foo={cppyy.gbl.foo}')
print( f'cppyy.gbl.N.bar={cppyy.gbl.N.BAR}')
print( f'cppyy.gbl.N.bar={cppyy.gbl.N.bar}')

show( cppyy.gbl)    # Now shows FOO and foo().

Output:

Thanks in advance for any help here.

Looks like upstream isn't providing any enums (still looking into that one).

The function is missing b/.c __dir__ didn't perform updates. Was b/c it used to leak, but that's no longer the case, so I added the forced update/load.

Thanks, good to know this is understood. Will try to figure out how to build cppyy myself and test with latest version.
