class FCADLogger:
    """
    Convenient class for tagged logging.

    Example usage:
        >>> logger = FreeCAD.Logger('MyModule')
        >>> logger.info('log test {}',1)
        24.36053 <MyModule> <input>(1): test log 1

    The default output format is:
        <timestamp> <tag> <source file>(line number): message

    The message is formatted using new style Python string formatting, e.g.
    'test {}'.format(1). It is strongly recommended to not directly use
    Python string formatting, but pass additional argument indirectly through
    various logger print function, because the logger can skip string
    evaluation in case the logging level is disabled. For more options,
    please consult the docstring of __init__(), catch() and report().

    To set/get logger level:
        >>> FreeCAD.setLogLevel('MyModule','Trace')
        >>> FreeCAD.getLogLevel('MyModule')
        4

    There are five predefined logger level, each corresponding to an integer
    value, as shown below together with the corresponding logger print
    method,
        0: Error, Logger.error()
        1: Warning, Logger.warn()
        2: Message, Logger.msg() or info()
        3: Log, Logger.log() or debug()
        4: Trace, Logger.trace()

    FreeCAD.setLogLevel() supports both text and integer value, which allows
    you to define your own levels. The level set is persisted to user
    configuration file.

    By default any tag has a log level of 2 for release, and 3 for debug
    build.
