Description
Consider the following code:
from enum import Enum
import click
class Color(str, Enum):
RED = "red"
GREEN = "green"
BLUE = "blue"
def __str__(self) -> str:
return self.value
@click.command()
@click.option("-C", "--color", type=click.Choice(list(Color)), show_default=True)
def main(color: Color) -> None:
print(repr(color))
if __name__ == "__main__":
main()With Click 8.1.8, running this script with -C red works as expected, but with Click 8.2.0, it instead fails with:
Usage: enum-choice01a.py [OPTIONS]
Try 'enum-choice01a.py --help' for help.
Error: Invalid value for '-C' / '--color': 'red' is not one of 'RED', 'GREEN', 'BLUE'.
This was observed with Python 3.13.3 on macOS 14.7.5.
