:Sample Code:
    .. code-block:: python

        from argparse import ArgumentParser

        from pathvalidate.argparse import validate_filename_arg, validate_filepath_arg

        parser = ArgumentParser()
        parser.add_argument("--filename", type=validate_filename_arg)
        parser.add_argument("--filepath", type=validate_filepath_arg)
        options = parser.parse_args()

        if options.filename:
            print(f"filename: {options.filename}")

        if options.filepath:
            print(f"filepath: {options.filepath}")

:Output:
    .. code-block:: none

        $ ./examples/argparse_validate.py --filename eg
        filename: eg
        $ ./examples/argparse_validate.py --filename e?g
        usage: argparse_validate.py [-h] [--filename FILENAME] [--filepath FILEPATH]
        argparse_validate.py: error: argument --filename: [PV1100] invalid characters found: invalids=(':'), value='e:g', platform=Windows

.. note::
    ``validate_filepath_arg`` consider ``platform`` as of ``"auto"`` if the input is an absolute file path.
