使用样例
>>> import logzero >>> from logzero import logger as log >>> from izen.icfg import Conf, LFormatter >>> pth_cfg = '/tmp/.code.cnf' >>> cfg = Conf( ... pth=pth_cfg, ... dat={ ... 'mg.host': '127.0.0.1', ... 'mg.port': 27027, ... 'mg.db': 'test_db', ... 'rds.host': '127.0.0.1', ... 'rds.port': 6379, ... 'rds.db': { ... 'val': 0, ... 'proto': str ... }, ... } ... ).cfg >>> if cfg.get('log.enabled', False): ... logzero.logfile( ... cfg.get('log.file_pth', '/tmp/.code.log'), ... maxBytes=cfg.get('log.file_size', 5) * 1000000, ... backupCount=cfg.get('log.file_backups', 3), ... loglevel=cfg.get('log.level', 10), ... ) ... >>> bagua = '🍺🍻♨️️😈☠' >>> formatter = LFormatter(bagua) >>> logzero.formatter(formatter) >>> >>> log.debug('hi') 🍺 D 180417 16:36:05 <stdin>:1 | hi >>> log.info('hi') 🍻 I 180417 16:37:21 <stdin>:1 | hi >>> log.warning('hi') ♨ W 180417 16:37:35 <stdin>:1 | hi >>> log.error('hi') ️ E 180417 16:37:41 <stdin>:1 | hi
装饰器
i.e. dec.catch
, 自动捕获函数内程序错误, 并保证其他函数可以正常运行
>>> from izen import dec >>> >>> >>> @dec.catch(True, ZeroDivisionError) ... def terr(): ... print('divide by 0') ... print(1 / 0) ... print('i can not go here.') ... >>> >>> def t(): ... terr() ... print('but i can go here.') ... >>> t() divide by 0 [E 180417 16:25:41 dec:457] <stdin>(1)>terr: has err(division by zero) Traceback (most recent call last): File "/Users/lihe/pan.weiyun/tinyc/smartwear/izen/izen/dec.py", line 452, in wrapper_ return fn(*args, **kwargs) File "<stdin>", line 4, in terr ZeroDivisionError: division by zero but i can go here.
