Configure additional log handlers. The default stderr logs handler is configured by the log_level, log_datefmt and log_format settings. This configuration can be used to configure additional handlers (e.g. to output the log to a file) or for finer control over the default handlers. If provided this should be a logging configuration dictionary, for more information see: https://docs.python.org/3/library/logging.config.html#logging-config-dictschema This dictionary is merged with the base logging configuration which defines the following: * A logging formatter intended for interactive use called ``console``. * A logging handler that writes to stderr called ``console`` which uses the formatter ``console``. * A logger with the name of this application set to ``DEBUG`` level. This example adds a new handler that writes to a file: .. code-block:: python c.Application.logging_config = { "handlers": { "file": { "class": "logging.FileHandler", "level": "DEBUG", "filename": "<path/to/file>", } }, "loggers": { "<application-name>": { "level": "DEBUG", # NOTE: if you don't list the default "console" # handler here then it will be disabled "handlers": ["console", "file"], }, }, } z log-levelzApplication.log_level�aliasesz5Set log-level to debug, for the most verbose logging.� show_configz<Show the application's configuration (human-readable format)�show_config_jsonz2Show the application's configuration (json format))r7 z show-configzshow-config-json�flagsz#dict[str, t.Any] | Dict[str, t.Any]� subcommandsz(traitlets.config.application.Application)� allow_noner< z�The subset of our configuration that came from the command-line We re-load this configuration after loading config files, to ensure that it maintains highest priority. z List[str]�_loaded_config_fileszAInstead of starting the Application, dump configuration to stdoutzKInstead of starting the Application, dump configuration to stdout (as JSON)c C s |j | _d S r� )�newr� r� r< r< r= �_show_config_json_changed� s z%Application._show_config_json_changedc C s |j r| j| _| j| _d S r� )r� �startZ _save_start�start_show_configr� r< r< r= �_show_config_changed� s z Application._show_config_changedr0 )r3 r. c K sR t j| fi |�� | j}|| jvrN| j|ju r>|g| j�| _n| j�d| j� d S )Nr )r �__init__rS r_ �insert)rQ r3 �clsr< r< r= r� � s zApplication.__init__r8 c s t � �|� | j�d|j� d S )NzConfig changed: %r)rO �_config_changedr5 r7 r� r� rR r< r= r� � s zApplication._config_changed�ArgvType)r$ r. c C s | � |� dS )zMDo the basic steps to configure me.
