Anti-Boilerplate Console Logging Module for Python
About
=====
*conlog* is a configurable console logging mechanism featuring:
- Boilerplate-free setup
- Only one line per Logger
- Export to optional rotating log file
- Show additional log columns when debugging, suppress when not
- YAML or argument based configuration
Installation
============
Install via pip: **(Recommended)**
::
pip install conlog
Or with setup_tools:
::
python setup.py install
Documentation
=============
Quick start
-----------
::
import conlog
log = conlog.start(level='INFO')
log.info('Hello World!')
Functions
---------
start(...)
""""""""""
::
start(
yaml_file=None,
log_file=None,
log_format='%(asctime)22s - %(levelname)8s - %(name)20s - %(message)s',
debug_format='%(asctime)22s - %(levelname)8s - %(name)20s - %(funcName)20s - %(message)s',
level='INFO',
max_file_size='5000000',
max_retention=5
)
Configure and return the root Logger instance. All parameters
are optional. If any parameter is not supplied, its default
value be used. It is even possible to run with no parameters,
in which case the default values would be used across all
options.
Parameters
''''''''''
:``yaml_file``:
Pull configurations from YAML file. All parameters from
``start()`` are available as YAML options. Option entries
should be nested under ``conlog`` at the root of the YAML
file. The file should be structured:
::
conlog:
log_file: log/app.log
log_format: '%(asctime)22s - %(levelname)8s - %(name)20s - %(message)s'
debug_format: '%(asctime)22s - %(levelname)8s - %(name)20s - %(funcName)20s - %(message)s'
level: INFO
max_file_size: 5 MB
max_retention: 5
Like ``start()`` parameters, all YAML settings are optional.
If any setting is not supplied in the configuration, its
default value will be used.
If ``yaml_file`` is supplied, its values are processed first,
and will be overridden by any additional parameters called in
``start()``
Default: ``None``
:``log_file``:
Path to log file. By default, file logging is disabled. If
``log_file`` is set to a file path, for example, ``log/app.log``,
it will enable rotating file logging.
NOTE: In the example ``log/app.log``, the log file itself,
``app.log``, does not need to exist; however, the base directory
``log`` MUST exist.
By default the log file will rotate when it reaches ``5 MB``,
with up to ``5`` rotations being kept before overwriting the oldest.
These values can be adjusted using the ``max_file_size`` and
``max_retention`` options.
Default: ``None``
:``log_format``:
Logging format for all levels EXCEPT ``DEBUG``.
Default: ``%(asctime)22s - %(levelname)8s - %(name)20s - %(message)s``
:``debug_format``:
Logging format for ``DEBUG`` level. By default, this displays the
same formatting as ``format``, but with an additional column for
the function name which is calling the Logger.
Default: ``%(asctime)22s - %(levelname)8s - %(name)20s - %(funcName)20s - %(message)s``
:``level``:
Logging level. Only messages sent to this level or higher will
appear in log.
Default: ``INFO``
:``max_file_size``:
Maximum log file size before rollover. This value can either
be an integer byte size or a proper string like: ``5 MB``,
``50 kB``, etc. Setting to ``0`` will cause the log file to
grow infinitely with no rollover. This option has no impact if
``log_file`` is set to ``None``.
Default: ``5000000`` (5 MB)
:``max_retention``:
Maximum number of rollover logs to keep. Rotated logs will be
saved in the format ``log_name.1``, ``log_name.2``, etc.,
until ``max_retention`` is reached. At that point the oldest
of the rollover logs will be purged. This option has no impact
if ``log_file`` is set to ``None``, or if ``max_file_size`` is
set to ``0``.
Default: ``5``
new(inst)
"""""""""
Get a new Logger instance for the calling class. Recommended
usage is ``self.log = conlog.new(self)``.
Parameters
''''''''''
:``inst``:
Instance of class which new Logger is for, (HINT: use ``self``)
**Required**
Examples
========
This is the easiest way to add a root Logger using conlog with ``INFO`` level
logging to the console.
::
log = conlog.start(level='INFO')
Start logging based on configuration in the YAML file, ``conf/conlog.yml``.
::
log = conlog.start(yaml_file='conf/conlog.yml')
Start ``DEBUG`` level Logger with console logging and rotating file logging to
``logs/app.log``.
::
log = conlog.start(
log_file='logs/app.log',
level='DEBUG'
)
Similar to above but with specific values set for rotation of log files. This
will rotate the log file when it reaches ``1 MB`` and retain up to ``10``
archived log files before overwriting the oldest.
::
log = conlog.start(
log_file='log/app.log',
level='INFO',
max_file_size='1 MB',
max_retention=10,
)
Start console logging with a different log format.
::
log = conlog.start(log_format='%(levelname)s:%(name)s:%(message)s')
Get a Logger instance for a class. (Remember to ``start()`` first)
::
class Example(object):
def __init__(self):
self.log = conlog.new(self)
