Wrap enum class for cython

Question

I am trying to wrap an enum class in a c++ header file for use in a cython project.I have googled around and can not find out how to achieve this - is it supported?

Answer 1

CPP class

enum class Color {red, green = 20, blue}; 

Definition of type

cdef extern from "colors.h":
  cdef cppclass Color:
    pass

Definition of color types

cdef extern from "colors.h" namespace "Color":
  cdef Color red
  cdef Color green
  cdef Color blue

Python implementation

cdef class PyColor:
  cdef Color thisobj
  def __cinit__(self, int val):
    self.thisobj =  val

  def get_color_type(self):
    cdef c = {red : "red",  green : "green",  blue : "blue"}
    return c[self.thisobj]
