Bases: BaseFormatter

ColoredBaseFormatter is used to format log record to create a string representing a log message. It is based on the BaseFormatter object which is based on the of the standard logging library.

This custom formatter is useful for format messages to correspond with the gLogger format. It adds color on all messages which come from StdoutBackend and StderrBackend and color them according to their levels.

COLOR_MAP = {'black': 0, 'blue': 4, 'cyan': 6, 'green': 2, 'magenta': 5, 'red': 1, 'white': 7, 'yellow': 3}
LEVEL_MAP = {'ALWAYS': ('black', 'white', False), 'DEBUG': (None, 'blue', False), 'ERROR': (None, 'red', False), 'FATAL': ('red', 'black', False), 'INFO': (None, 'green', False), 'NOTICE': (None, 'magenta', False), 'VERBOSE': (None, 'cyan', False), 'WARN': (None, 'yellow', False)}
__init__(fmt=None, datefmt=None)

Initialize the formatter without using parameters. They are then modified in format()

  • fmt (str) – log format: “%(asctime)s UTC %(name)s %(levelname)s: %(message)”

  • datefmt (str) – date format: “%Y-%m-%d %H:%M:%S”

gmtime([seconds]) -> (tm_year, tm_mon, tm_mday, tm_hour, tm_min,

tm_sec, tm_wday, tm_yday, tm_isdst)

Convert seconds since the Epoch to a time tuple expressing UTC (a.k.a. GMT). When ‘seconds’ is not passed in, convert the current time instead.

If the platform supports the tm_gmtoff and tm_zone, they are available as attributes only.

default_msec_format = '%s,%03d'
default_time_format = '%Y-%m-%d %H:%M:%S'

Overriding. format is the main method of the Formatter object because it is the method which transforms a log record into a string with colors. According to the level, the method get colors from LEVEL_MAP to add them to the message.


record – the log record containing all the information about the log message: name, level, threadid…


Format and return the specified exception information as a string.

This default implementation just uses traceback.print_exception()


This method is provided as an extension point for specialized formatting of stack information.

The input data is a string as returned from a call to traceback.print_stack(), but with the last trailing newline removed.

The base implementation just returns the value passed in.

formatTime(record, datefmt=None)

Return the creation time of the specified LogRecord as formatted text.

This method should be called from format() by a formatter which wants to make use of a formatted time. This method can be overridden in formatters to provide for any specific requirement, but the basic behaviour is as follows: if datefmt (a string) is specified, it is used with time.strftime() to format the creation time of the record. Otherwise, an ISO8601-like (or RFC 3339-like) format is used. The resulting string is returned. This function uses a user-configurable function to convert the creation time to a tuple. By default, time.localtime() is used; to change this for a particular formatter instance, set the ‘converter’ attribute to a function with the same signature as time.localtime() or time.gmtime(). To change it for all formatters, for example if you want all logging times to be shown in GMT, set the ‘converter’ attribute in the Formatter class.


Check if the format uses the creation time of the record.
