Logging

How can we print log statements from the luan code?
Example:

Log.info('a')
Log.debug('b')
Log.error('c')
Log.warn('d')

I am not sure how this would work with luanhost, but I need this to debug my code.

local logger = Logging.logger "test"

logger.info('a')
logger.debug('b')
logger.error('c')
logger.warn('d')

Thanks, closing thread.
