Logging

Slave makes use of python’s standard logging module. It is quite useful for development of new device drivers and diagnosing of communication errors.

You can use it in the following way:

import logging

logging.basicConfig(filename='log.txt', filemode='w', level=logging.DEBUG)

# Now use slave ...

Note

Be careful, IPython adds a default handler. Therefore logging.basicConfig is a no op.

A more complicated setup could look like this:

import logging.config

LOG_CFG = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'stream': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
        },
    },
    'root': {
        'handlers': ['stream'],
        'level': 'DEBUG',
        'propagate': True,
    },
}
logging.config.dictConfig(LOG_CFG)
