import a full c enum using cython automatically

Question

im using cython to import c enums from .h file to my python code (the goal is to have one place that will include the enums for both of my programs). so i have my enums.h file:

typedef enum Numbers{
    ONE=1, TWO, THREE
} Numbers;

and i have my enums.pyx

cdef extern from "enums.h":
    cpdef enum Numbers:
        ONE,
        TWO,
        THREE

and this code works in the sense that it imports the enum to be accessible from the python code with the right values. i want to take it a step further and want to automatically identify the members of the c enums, so the pyx file would update automaticly, when i do:

cdef extern from "enums.h":
    cpdef enum Numbers:
        pass

i get a Numbers enum in the python but without members (so even if I do Numbers(1) ill get an error).

is there a way to identify the c enum members automatically?

Answer 1

Cython does not have any ability to scan C files and generate declarations so the direct answer to your question is "no" and is very likely to remain "no".

Other tools do have greater introspection ability. CFFI for example . I'm sure there are others.

You could obviously write a short script using one of these tools to try to generate (parts of) your automatically Cython files, but it's definitely outside the scope of Cython on its own.
