丰富的回溯记录器
rich-traceback的Python项目详细描述
python的信息性回溯日志记录
显示方法参数的信息堆栈跟踪。 支持控制台系统日志的简单独立记录器。
用法：
- 如果您已经在使用日志模块，请在模块中导入rich_traceback.enable。然后logger.exception（）将报告格式良好的异常。
导入富跟踪。启用
- 否则，使用richtracebackformatter类创建一个新的记录器，或者以rich traceback.log为例：
（另存为test.py）
from rich_traceback.formatter import RichTracebackFormatter
import logging
logger = logging.getLogger('root')
console_log = logging.StreamHandler()
console_log.setFormatter(RichTracebackFormatter())
logger.addHandler(console_log)
def foo(x=3):
if 1.0/x:
foo(x-1)
try:
foo()
except:
logger.exception("error running foo")
print "compare with standard Python traceback"
foo() # for standard traceback
$ python test.py
ERROR root test.<module>:15 error running foo
<type 'exceptions.ZeroDivisionError'>: ZeroDivisionError('float division by zero',) ([5] frames following)
