An improved ArgumentParser.

Gooey (GUI) generation support

Not sure if you've heard of this project, kinda cool: https://github.com/chriskiehl/Gooey

Would be great to have apeagears support

How to provide arguments to custom class?

Attempt:

@classmethod
def from_string(cls, s):
    return cls(**loads(s))

@classmethod
def __argparse__(cls):
    return dict(from_string=cls.from_string)

But this just puts it all on the first argument, like so:

$ ipython3
Python 3.8.6 (default, Oct  8 2020, 14:06:32) 
Type 'copyright', 'credits' or 'license' for more information
IPython 8.0.0.dev -- An enhanced Interactive Python. Type '?' for help.

In [1]: from apegears import ArgumentParser, register_spec

In [2]: from ml_params_tensorflow.ml_params.config import TrainConfig

In [3]: from json import loads

In [4]: parser = ArgumentParser()

In [5]: parser.add_argument('-t', type=TrainConfig)
Out[5]: _StoreAction(option_strings=['-t'], dest='t', nargs=None, const=None, default=None, type=<class 'ml_params_tensorflow.ml_params.config.TrainConfig'>, choices=None, help=None, metavar=None)

In [6]: parser.parse_args(['-t', '{"epochs": 1, "loss": "CategoricalCrossentropy", "optimizer": "Adam", "callbacks": ["TensorBoard"], "metrics": [], "m
   ...: etric_emit_freq": None, "save_directory": None, "output_type": "infer", "validation_split": 0.2, "batch_size": 128, "kwargs": None, "return_typ
   ...: e": None}'])
Out[6]: Namespace(t=TrainConfig(epochs='{"epochs": 1, "loss": "CategoricalCrossentropy", "optimizer": "Adam", "callbacks": ["TensorBoard"], "metrics": [], "metric_emit_freq": None, "save_directory": None, "output_type": "infer", "validation_split": 0.2, "batch_size": 128, "kwargs": None, "return_type": None}', loss=None, optimizer=None, callbacks=None, metrics=None, metric_emit_freq=None, save_directory=None, output_type='infer', validation_split=0.1, batch_size=128, kwargs=None, return_type=<_collections._tuplegetter object at 0x106af1970>))

I'm sure I'm doing something wrong. I've also tried without classmethod and just manipulating the class symbol that I import in…

What's the right way to pass many arguments to the given class type? - Also is there a way to give per argument --help text and errors?

Happy to help implement. https://github.com/SamuelMarks/doctrans is what I'm working on.

Thanks for making apegears
