colorlog 0.4

Log formatting with colors!

colorlog.ColoredFormatter is a formatter for use with pythons logging module.

It allows colors to be placed in the format string, which is mostly useful when paired with a StreamHandler that is outputting to a terminal. This is accomplished by added a set of terminal color codes to the record before it is used to format the string.

Usage

ColoredFormatter requires at minumum a format string, and takes two options - reset and color_levels, which are shown using values equivalent to the defaults the following example.

from colorlog import ColoredFormatter

formatstring = "%(bg_level)s%(levelname)-8s%(reset)s %(blue)%(message)s"

levels = {
        'DEBUG':    'cyan',
        'INFO':     'green',
        'WARNING':  'yellow',
        'ERROR':    'red',
        'CRITICAL': 'red',
}

formatter = ColoredFormatter(formatstring, reset=True, color_levels=levels)

The formatter can then be used in a normal logging setup.
