``colorlog.ColoredFormatter`` is a formatter for use with pythons logging module.
It allows colors to be placed in the format string, which is mostly useful when paired with a StreamHandler that is outputting to a terminal. This is accomplished by added a set of terminal color codes to the record before it is used to format the string.
Codes
=====
The following values are made availible for use in the format string:
- ``{color}``, ``fg_{color}``, ``bg_{color}``: Foreground and background colors. The color names are ``black``, ``red``, ``green``, ``yellow``, ``blue``, ``purple``, ``cyan`` and ``white``.
- ``bold``, ``bold_{color}``, ``fg_bold_{color}``, ``bg_bold_{color}``: Bold/bright colors.
- ``reset``: Clear all formatting (both foreground and background colors).
- ``log_color``: Return the color associated with the records level (from ``color_levels``).
Arguments
=========
``ColoredFormatter`` takes several arguments:
- ``format``: The format string used to output the message (required).
- ``datefmt``: An optional date format passed to the base class. See `logging.Formatter`_.
- ``reset``: Implicitly adds a color reset code to the message output, unless the output already ends with one. Defaults to ``True``.
- ``log_colors``: A mapping of record level names to color names. The defaults can be found in ``colorlog.default_log_colors``, or the below example.
- ``style``: Available on Python 3.2 and above. See `logging.Formatter`_.
Examples
========

:alt: Example output
The following code creates a ColoredFormatter for use in a logging setup, passing each arguments defaults to the constructor::
from colorlog import ColoredFormatter
formatter = ColoredFormatter(
"%(log_color)s%(levelname)-8s%(reset)s %(blue)s%(message)s",
datefmt=None,
reset=True,
log_colors={
'DEBUG': 'cyan',
'INFO': 'green',
'WARNING': 'yellow',
'ERROR': 'red',
'CRITICAL': 'red',
}
)
With `dictConfig`_
------------------
::
logging.config.dictConfig({
'formatters': {
'colored': {
'()': 'colorlog.ColoredFormatter',
'format': "%(log_color)s%(levelname)-8s%(reset)s %(blue)s%(message)s"
}
},
...
})
A full example dictionary can be found in ``tests/test_colorlog.py``.
With `fileConfig`_
------------------
::
...
[formatters]
keys=color
[formatter_color]
class=colorlog.ColoredFormatter
format=%(log_color)s%(levelname)-8s%(reset)s %(bg_blue)s[%(name)s]%(reset)s %(message)s from fileConfig
datefmt=%m-%d %H:%M:%S
...
An instance of ColoredFormatter created with those arguments will then be used by any handlers that are configured to use the ``color`` formatter.
A full example configuration can be found in ``tests/test_config.ini``.
Compatibility
=============
colorlog works on Python 2.6 and above, including Python 3.
On Windows, requires `colorama`_ to work properly. A dependancy on `colorama`_ is included as an optional package dependancy - depending on ``colorlog[windows]`` instead of ``colorlog`` will ensure it is included when installing.
Tests
=====
Tests similar to the above examples are found in ``tests/test_colorlog.py``.
`tox`_ will run the tests under all compatible python versions.
