Usage

ColoredFormatter requires at minumum a format string, and takes two options - reset (implictly add a reset code at the end of message strings, defaults to true) and color_levels (a mapping of record level names to color names, defaults to colorlog.DEFAULT_COLOR_LEVELS).

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.

Codes

The following values are made availible for use in the format string:

• fg_{colorname}, bg_{colorname}: Foreground and background colors. The colors names are black, red, green, yellow, blue, purple, cyan and white.

• bold: Bold output.

• reset: Clear all formatting (both foreground and background colors).

• fg_level, bg_level: Return the color associated with the records level (from color_levels).
