Belogging
=========
*Don't fight with logging ...*
|TravisCI Build Status| |Coverage Status| |PyPI Version| |PyPI License| |PyPI latest|
----
Easy logging configuration based on environment variables.
Features:
* Set logging level using environment variable LOG_LEVEL (defaults to 'INFO')
* Set which loggers to enable using environment variable LOGGERS (defaults to '', everything)
* Always output to stdout
* Optional JSON formatter
* Completely disable logging setting LOG_LEVEL=DISABLED
Requirements:
* Python 3.5 and beyond
Install:
`pip install belogging`
Examples:
---------
Simple applications:
~~~~~~~~~~~~~~~~~~~~
.. code-block:: python
# my_script.py
import belogging
belogging.load()
# ^^ this call is optional, only useful for customization
# For example, to enable JSON output: belogging.load(json=True)
# belogging.getLogger is just a sugar to logging.getLogger, you can
# use logging.getLogger as usual (and recommended).
logger = belogging.getLogger('foobar')
logger.debug('test 1')
logger.info('test 2')
Executing:
.. code-block:: bash
# selecting LOG_LEVEL
$ LOG_LEVEL=DEBUG python my_script.py
# level=DEBUG message=test 1
# level=INFO message=test 2
# selecting LOGGERS
$ LOGGERS=foobar python my_script.py
# Both messages
# Both
$ LOGGERS=foobar LOG_LEVEL=INFO my_script.py
# only level=INFO message=test 2
Applications should call ```belogging.load()``` upon initialization.
The first ```__init__.py``` would be a good candidate, but anything before any call to
```logging``` module will be fine.
Django:
~~~~~~~
In your projects ```settings.py```:
.. code-block:: python
import belogging
# Disable django logging setup
LOGGING_CONFIG = None
belogging.load()
Inside your code, just use ```logging.getLogger()``` as usual.
.. code-block:: bash
$ export LOG_LEVEL=WARNING
$ ./manage.py runserver
# It will output only logging messages with severity > WARNING
Logging follows a hierarchy, so you easily select or skip some logging messages:
.. code-block:: bash
$ export LOGGERS=my_app.critical_a,my_app.critical_c,my_lib
$ ./my-app.py
# "my_app.critical_b messages" will be skipped
# all messages from my_lib will show up
