A collection of structlog_ processors for prettier output: a code syntax highlighter, JSON and XML prettifiers, a multiline string printer, and a numeric value rounder.

Installation

First of all, sorry, grandma, but structlog-pretty requires Python 3.

You can just install the library with pip::

pip install structlog-pretty

or, if you want faster prettifying processors::

pip install structlog-pretty[fast]

The downside of the faster processors is that they will build C extensions and they need libxml to be installed.

Usage

Add structlog-pretty processors to your structlog configuration

.. code-block:: python

import structlog
import structlog_pretty

structlog.configure(
    # ...
    processors=[
        structlog.stdlib.add_log_level,
        structlog_pretty.NumericRounder(digits=2, only_fields=['timing'])
        structlog.processors.JSONRenderer(),
    ],
)

A nice example of a processor pipeline for the prettiest logs could be

.. code-block:: python

processors=[
    # ...
    structlog_pretty.JSONPrettifier(['request', 'response']),
    structlog_pretty.XMLPrettifier(['soap_response']),
    structlog_pretty.PathPrettifier(),
    structlog_pretty.SyntaxHighlighter({'request': 'json', 'response': 'json', 'soap_response': 'xml'}),
    structlog_pretty.MultilinePrinter(['request', 'response', 'soap_response']),
    # ...
],
