Usage

By loading this plugin, configmate will use Pydantic to validate the config. Under the hood, a new validator is registered to configmate.components.validators.TypeValidatorFactory. This validator will be used for any non-function passed to validation in configmate.get_config.

from typing import Dict
import dataclasses

import configmate

@dataclasses.dataclass
class Config:
    host: str
    port: int

config = configmate.get_config(
    "config.json",  # main config
    validation=Dict[str, str], # pydantic will handle validation
)
## >> {'host': 'localhost', 'port': '8080'} # note that port is a string due to pydantic

config = configmate.get_config(
    "config.json",  # main config
    validation=Config, # pydantic will handle validation
) 
## >> Config(host='localhost', port=8080) # port is an int as expected

config = configmate.get_config(
    "config.json",  # main config
    validation=lambda config_dict: ..., # callables will be called with the config dict (as without this plugin)
)
## >> ... # whatever the callable returns
