Checks your python enums. Eliminates common attribute errors and name conflicts.
Enumchecker checks for common mistakes with enums, including conflicting class definitions and the use of enums that don't exist. For example:
from enum import Enum
class MyEnum(Enum):
a = "a"
b = "b"
def check(x):
if x == MyEnum.c: # <- AttributeError
print("x was 'c'")
You can call the script directly via python enumchecker.py --dirname <dir>, to check all files in a directory. Alternatively, once installed, you can invoke the enumchecker command.
The script enumchecker.py is a good resource for learning about python's ast module. It searches through class definitions and looks for subclasses of the Enum class. It's not foolproof - by reading the source code you can probably think of a few ways to fool it!
