My logging improvement

Project description

BetterLogging

BetterLogging

Improved version of the standard logger.

  • Added TRACE level.
  • Added ColorizedFormatter.
  • Added better traceback formatting.

This package patching the standard logging library.

Thus, after import, all improvements will be available inside the logging module.

But for better typing, I prefer to use betterlogging everywhere.

Requirements

Python 3.6 and above. No any additional dependencies.

Installation

pip install betterlogging

Usage

Simple usage

import betterlogging as logging

logging.basic_colorized_config(level=logging.INFO)

logger = logging.getLogger('test')

logger.trace("some trace message")
logger.debug("some debug message")
logger.info("some info message")
logger.warning("some warning message")
logger.error("some error message")
logger.critical("some critical message")

More advanced usage

import betterlogging as logging


# You can use shortcut:
logger = logging.get_colorized_logger(name="test")

# Or, if you want to configure formatter:
handler = logging.StreamHandler()
handler.setFormatter(logging.ColorizedFormatter(hide_lib_diagnose=False))

logger.addHandler(handler)
logger.setLevel(logging.TRACE)

logger.trace("some trace message")
logger.debug("some debug message")
logger.info("some info message")
logger.warning("some warning message")
logger.error("some error message")
logger.critical("some critical message")

def div(x: int, y: int) -> float:
    return x / y

try:
    div(1, 0)
except:
    logger.exception("Some exception")
