pydantic-parse

Pydantic adaptor for argparse

Example

def main():

    class TestChoices(enum.StrEnum):
        alice = "Alice"
        bob = "Bob"

    class TestModel(ArgModel):
        name: TestChoices = ArgField(description="Name")
        some_value: Optional[str] = ArgField(
            description="value",
            optional=True,
            default=None,
            flag=True
        )
        flag: bool = ArgField(description="flag", default=False, flag=True)

    parser = PydanticArgParser()
    parser.add_arguments_from_model(TestModel)
    args = parser.parse_args()

CLI

my-package Alice --some-value 42

Results in vars(args):

{
  'name': <TestChoices.alice: 'Alice'>,
  'some_value': '42',
  'flag': False
}

Or of course

model = TestModel(**vars(args))

gives

TestModel
name=<TestChoices.alice: 'Alice'> some_value='42' flag=False
