Example comparing the use of `HfArg` and `dataclasses.field`: ``` @dataclass class Args: regular_arg: str = dataclasses.field(default="Huggingface", metadata={"aliases": ["--example", "-e"], "help": "This syntax could be better!"}) hf_arg: str = HfArg(default="Huggingface", aliases=["--example", "-e"], help="What a nice syntax!") ``` Args: aliases (Union[str, List[str]], optional): Single string or list of strings of aliases to pass on to argparse, e.g. `aliases=["--example", "-e"]`. Defaults to None. help (str, optional): Help string to pass on to argparse that can be displayed with --help. Defaults to None. default (Any, optional): Default value for the argument. If not default or default_factory is specified, the argument is required. Defaults to dataclasses.MISSING. default_factory (Callable[[], Any], optional): The default_factory is a 0-argument function called to initialize a field's value. It is useful to provide default values for mutable types, e.g. lists: `default_factory=list`. Mutually exclusive with `default=`. Defaults to dataclasses.MISSING. metadata (dict, optional): Further metadata to pass on to `dataclasses.field`. Defaults to None. Returns: Field: A `dataclasses.Field` with the desired properties.

This relies on argparse's `ArgumentParser.parse_known_args`. See the doc at: docs.python.org/3.7/library/argparse.html#argparse.ArgumentParser.parse_args Args: args: List of strings to parse. The default is taken from sys.argv. (same as argparse.ArgumentParser) return_remaining_strings: If true, also return a list of remaining argument strings. look_for_args_file: If true, will look for a ".args" file with the same base name as the entry point script for this process, and will append its potential content to the command line args. args_filename: If not None, will uses this file instead of the ".args" file specified in the previous argument. args_file_flag: If not None, will look for a file in the command-line args specified with this flag. The flag can be specified multiple times and precedence is determined by the order (last one wins). Returns: Tuple consisting of: - the dataclass instances in the same order as they were passed to the initializer.abspath - if applicable, an additional namespace for more (non-dataclass backed) arguments added to the parser after initialization. - The potential list of remaining argument strings.
