http://github.com/laysakura/rainbow_logging_handler/raw/master/doc/screenshot.png

This script runs like above screenshot.

import sys
import logging
from rainbow_logging_handler import RainbowLoggingHandler

def main_func():
    # setup `logging` module
    logger = logging.getLogger('test_logging')
    logger.setLevel(logging.DEBUG)
    formatter = logging.Formatter("[%(asctime)s] %(name)s %(funcName)s():%(lineno)d\t%(message)s")  # same as default

    # setup `RainbowLoggingHandler`
    handler = RainbowLoggingHandler(sys.stderr, color_funcName=('black', 'yellow', True))
    handler.setFormatter(formatter)
    logger.addHandler(handler)

    logger.debug("debug msg")
    logger.info("info msg")
    logger.warn("warn msg")
    logger.error("error msg")
    logger.critical("critical msg")

    try:
        raise RuntimeError("Opa!")
    except Exception as e:
        logger.exception(e)

if __name__ == '__main__':
    main_func()

Features

Column-by-column colored log

As apparent from above screenshot, each column of logs are differently colored. Even default coloring should make log reading easier.

User custom color

Every column colors are customizable.

formatter = logging.Formatter('%(pathname)s [%(module)s] - %(funcName)s:L%(lineno)d : %(message)s')
handler   = RainbowLoggingHandler(
    sys.stderr,
    # Customizing each column's color
    color_pathname=('black', 'red'  , True), color_module=('yellow', None, False),
    color_funcName=('blue' , 'white', True), color_lineno=('green' , None, False),
)
handler.setFormatter(formatter)
logger.addHandler(handler)
logger.info("hello custom world")

Above code produces output like this.
