Filtering logging messages in Python scripts ============================================ All messages printed by the Hyperion Python routines use the built-in `logging `_ module. This means that it is possible to filter messages based on importance. Messages can have one of several levels: * ``DEBUG`` (``10``): detailed information, typically of interest only when diagnosing problems. * ``INFO`` (``20``): confirmation that things are working as expected * ``WARNING`` (``30``): An indication that something unexpected happened, or indicative of some problem in the near future. The program is still working as expected. * ``ERROR`` (``40``): due to a more serious problem, the program has not been able to perform some function (but no exception is being raised). * ``CRITICAL`` (``50``): a serious error, indicating that the program itself may be unable to continue running (but no exception is being raised). Note that the ``CRITICAL`` level is unlikely to be used, since critical errors should raise Exceptions in practice. It is possible to specify a threshold for logging messages. Messages which are less severe than this threshold will be ignored. The default threshold in Hyperion is ``20`` (``INFO``), indicating that all the above messages will be shown except ``DEBUG``. Using 40 for example would cause only ``ERROR`` and ``CRITICAL`` messages to be shown. By directly accessing the Hyperion logger ----------------------------------------- If you want to filter different messages in different scripts, you can directly access the logger and set the level manually:: from hyperion.util.logger import logger logger.setLevel(10) Using the Hyperion configuration file ------------------------------------- If you want to always filter the same messages for all projects on a given computer, you can create a ``.hyperionrc`` file in your home directory, containing the following entries related to logging:: [logging] color:yes level:0
