Argdcls

A simple tool to use dataclass as your config.

Usage

from dataclasses import dataclass

import argdcls


@dataclass
class Config:
    lr: float
    adam: bool = False


config = argdcls.load(Config)
print(config)

$ python3 main.py @lr=1.0
Config(lr=1.0, adam=False)
$ python3 main.py lr=1.0 adam=True
Config(lr=1.0, adam=True)
$ python3 main.py lr=1.0 adm=True # typo!
Parameter \"adm\" is not in the dataclass fields: ['lr', 'adam'].
$ python3 main.py lr=1.0 @adam=True # avoid overwriting
Parameter "adam" must have no default value but have default value: "False". You may use "adam=True" instead.

@param=value avoids overwriting the default values.

Benefits

• Attribute suggestions from IDEs (e.g., config.a<tab> indicates config.adam)
