Differents logging levels are available : trace, debug, info, warning, error and critical.
Examples of usage:
from kivy.logger import Logger Logger.info('title: This is a info message.') Logger.debug('title: This is a debug message.') try: raise Exception('bleh') except Exception: Logger.exception('Something happened!')
The message passed to the logger is split into two parts, separated by a colon (:). The first part is used as a title, and the second part is used as the message. This way, you can “categorize” your message easily.
Logger.info('Application: This is a test') # will appear as [INFO ] [Application ] This is a test
The Logger can be controlled via the Kivy configuration file:
[kivy] log_level = info log_enable = 1 log_dir = logs log_name = kivy_%y-%m-%d_%_.txt
More information about the allowed values are described in the
Even if the logger is not enabled, you still have access to the last 100 messages:
from kivy.logger import LoggerHistory print(LoggerHistory.history)
Logger= <logging.Logger object>¶
Kivy default logger instance
