Usage

from logging import getLogger, Logger, StreamHandler
from os import getenv

from aiocli.commander import run_app, Application, Depends, State

app = Application(state={
    'envs': {
        'LOGGER_NAME': str(getenv('LOGGER_NAME', 'example_app')),
        'LOGGER_LEVEL': str(getenv('LOGGER_LEVEL', 'INFO')),
    }
})

def _get_logger(state: State) -> Logger:
    logger = getLogger(state.get('envs')['LOGGER_NAME'])
    logger.setLevel(state.get('envs')['LOGGER_LEVEL'])
    handler = StreamHandler()
    logger.addHandler(handler)
    return logger

@app.command(name='greet:to', positionals=[('name', {'default': 'World!'})])
async def handle_greeting(name: str, logger: Logger = Depends(_get_logger)) -> int:
    logger.info(f'Hello {name}')
    return 0

@app.command(name='div', optionals=[('--a', {'type': float}), ('--b', {'type': float})])
async def handle_division(a: float, b: float, logger: Logger = Depends(_get_logger)) -> int:
    try:
        logger.info(f'Result {a} / {b} = {(a / b)}')
        return 0
    except BaseException as err:
        logger.error(f'Error: {err}')
        return 1
