logging-setup

A ready-made configuration for Python's standard logging module. Call init_logging() once, and the whole project gets colored console output, daily log files, and automatic cleanup.

Features

• Colored console output (DEBUG white, INFO cyan, WARNING yellow, ERROR red, CRITICAL bright red)
• STDOUT gets messages up to WARNING, STDERR gets ERROR and above
• Daily log files (UTC):
  • logs/app-YYYY-MM-DD.log for DEBUG to WARNING
  • logs/error-YYYY-MM-DD.log for ERROR and CRITICAL
• Old logs are deleted automatically (default: older than 30 days), once at startup and then every day
• No need for logging.getLogger(__name__): logging.info(...) shows the real module name (for example app.bot) instead of root
• Uncaught exceptions in the main thread and in other threads are logged as errors
• Noisy libraries (urllib3, aiohttp, selenium, telethon, pyrogram, asyncio, apscheduler) are limited to WARNING
• Calling init_logging() twice is safe: the second call is ignored

Requirements

• Python 3.11+
• colorama
• APScheduler

Installation

pip install loggingsetup

With uv:

uv add loggingsetup

The package name is loggingsetup, but the import name is logging_setup.

Quick start

In your main script, call it once:

import logging
from logging_setup import init_logging

init_logging()

logging.info("Hello World!")

In every other module, just use the standard logging:

import logging

def run():
    logging.info("Bot started")
    logging.error("Something went wrong")

Example output:

2026-10-20 09:42:16 | INFO     | app.bot | Bot started
2026-10-20 09:42:16 | ERROR    | app.bot | Something went wrong

logger = logging.getLogger(__name__) still works if you prefer it.

Parameters

init_logging(directory="my_logs", enable_console=False, days_to_delete_old_logs=14)

Project structure

logging_setup/
├── __init__.py          # exports init_logging
├── my_setup.py          # main setup function
├── formats.py           # color formatter, rotating handler, module name factory
├── filters.py           # level filters, exception hooks
└── cleanup_old_logs.py  # background cleanup of old log files

Notes

• The module name is calculated from the file path relative to the current working directory. Run your project from its root folder, so app/bot.py is shown as app.bot.
• The entry script is shown as main, not __main__.
• Old files are deleted only by the cleanup job, not by backupCount.
