I first ask this on python users. But I think the only people that can answer are the core developers.
I have a python3 C++ extension that works written using the PyCXX C++ interface.
But dir(obj) does not return the list of member variables.
With the python2 version supporting the __members__ variable was all that was needed. But __members__ been removed from python3.
How should I support dir() from the C API?
I cannot use tp_members, not appropiate to the code I'm writing. If I provide __dir__ I then hit the problem I need the C API version of:
all_attr = super( mytype, obj ).__dir__(); all_attr.extend( mytype_variable_names ); return all_attr
I'm not getting inspiration from the python 3.6 sources for this problem.
I did find the object_dir function in typeobject.c, but that has not helped get me move forward.
What is the the patten that I should implement?
