Project Description

Ultimate Python colorized logger.

Usage

Generic usage example

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()

Usage with Django

Django is a popular Python web framework.

Put the following to your settings.py to get more pleasant development server console output:

# Add this to your settings.py
if DEBUG:
    # Install rainbow logging handler when running Django in develoment mode
    import sys
    LOGGING["handlers"]["rainbow"] = {"level": "DEBUG", "class": "rainbow_logging_handler.RainbowLoggingHandler", 'stream': sys.stderr}
    LOGGING["loggers"]['']["handlers"].append("rainbow")

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.

High portability

Linux, BSD, Mac OS, and Windows are supposed to be supported.

Runs with both Python 2.6 or higher & Python 3.2 or higher.
