enum-prop

Enum definitions can't, for good reasons, reference instances of themselves within their own definitions. This module allows definitions to come around that by mapping the names of enums for lookups, hidden behind a special dict subclass. This allows enum definitions to remain tidy, and avoids having to define instance-specific configuration as property functions.

Installation

$ python3 -m pip install enum-prop

Usage

import enum
from enum_prop import enum_property, enum_getter

class Vehicle(enum.Enum):
    car = "car"
    bike = "bike"
    unicycle = "unicycle"
    wheels = enum_property({car: 4, bike: 2, unicycle: 1})
    __int__ = enum_getter({car: 4, bike: 2, unicycle: 1})

print(Vehicle.unicycle.wheels)  # 1
print(Vehicle.car.wheels)  # 4
print(int(Vehicle.unicycle))  # 1
print(int(Vehicle.bike))  # 2
