def addLoggingLevel(levelName, levelNum, methodName=None):
|

"""
|
|
Comprehensively adds a new logging level to the `logging` module and the
|
|
currently configured logging class.
|
|
|
|
`levelName` becomes an attribute of the `logging` module with the value
|
|
`levelNum`. `methodName` becomes a convenience method for both `logging`
|
|
itself and the class returned by `logging.getLoggerClass()` (usually just
|
|
`logging.Logger`). If `methodName` is not specified, `levelName.lower()` is
|
|
used.
|
|
|
|
To avoid accidental clobberings of existing attributes, this method will
|
|
raise an `AttributeError` if the level name is already an attribute of the
|
|
`logging` module or if the method name is already present
|
|
|
|
Example
|
|
-------
|
|
>>> addLoggingLevel('TRACE', logging.DEBUG - 5)
|
|
>>> logging.getLogger(__name__).setLevel("TRACE")
|
|
>>> logging.getLogger(__name__).trace('that worked')
|
|
>>> logging.trace('so did this')
|
|
>>> logging.TRACE
