Nice Log
Provide formatters to nicely display colorful logging output on the console.
Right now, it contains only one formatter, coloring log lines depending on the log level and adding nice line prefixes containing logger name, but future plans are to add more formatters and allow better ways to customize them.
Installation
pip install nicelog
Quick usage
Since version 0.3, nicelog comes with a helper function to quickly
set up logging for basic needs.
from nicelog import setup_logging
setup_logging()Or, if you want to include debug messages too:
setup_logging(debug=True)Advanced usage
import logging
import sys
from nicelog.formatters import Colorful
# Setup a logger
logger = logging.getLogger('foo')
logger.setLevel(logging.DEBUG)
# Setup a handler, writing colorful output
# to the console
handler = logging.StreamHandler(sys.stderr)
handler.setFormatter(Colorful())
handler.setLevel(logging.DEBUG)
logger.addHandler(handler)
# Now log some messages..
logger.debug('Debug message')
logger.info('Info message')
logger.warning('Warning message')
logger.error('Error message')
logger.critical('Critical message')
try:
raise ValueError('This is an exception')
except:
logger.exception("An error occurred")Example output
Here it is, in all its glory:
The output format can be further customized, eg. if you want to reduce colorfulness or verbosity.
Integrations
Django
I usually put something like this in my (local) settings:
LOGGING['formatters']['standard'] = {
'()': 'nicelog.formatters.Colorful',
'show_date': True,
'show_function': True,
'show_filename': True,
'message_inline': False,
}
