======= cutelog

This is a graphical log viewer for Python's standard logging module. It can be targeted with a SocketHandler with no additional setup (see Usage_). cutelog is cross-platform, although it's mainly written and optimized for Linux.

Features

• Allows any number of simultaneous connections
• Customizable look of log levels and columns, with presets for each
• Filtering based on level and namespace, as well as filtering by searching
• Search through all records or only through filtered ones
• Display extra fields under the message with Extra mode <https://github.com/busimus/cutelog/wiki/Creating-a-client-for-cutelog#extra-mode>_
• View exception tracebacks or messages in a separate window
• Dark theme (with its own set of colors for levels)
• Pop tabs out of the window, merge records of multiple tabs into one
• Save/load records to/from a file in JSON format

Installation

If you're using Linux, install PyQt5 (or PySide2) from your package manager before installing cutelog (package name is probably python3-pyqt5 or python-pyqt5). Or just run pip install pyqt5 to install it from pip, which is sub-optimal. ::

$ pip install --upgrade cutelog

Or install the latest development version from the source::

$ pip install git+https://github.com/busimus/cutelog.git

Requirements

• Python 3.5 (or newer)
• PyQt5 (preferably 5.6 or newer) or PySide2
• QtPy

Usage

1. Start cutelog

2. Put the following into your code:

.. code-block :: python

import logging
from logging.handlers import SocketHandler

log = logging.getLogger('Root logger')
log.setLevel(1)  # to send all messages to cutelog
socket_handler = SocketHandler('127.0.0.1', 19996)  # default listening address
log.addHandler(socket_handler)
log.info('Hello world!')

Afterwards it's recommended to designate different loggers for different parts of your program with log_2 = log.getChild("Child logger"). This will create "log namespaces" which allow you to filter out messages from various subsystems of your program.
