Update Advanced Python Logger

A feature-rich logging solution with file rotation, size-based cleanup, and configurable formatting.

Features

• вњ… Multi-level logging (INFO, WARN, ERROR, CRIT, DEBUG)
• рџ“Ѓ Automatic log rotation by size and age
• рџ“ќ Dual output (console + file) with toggle capability
• 🧹 Automatic cleanup of old log files
• рџ›  Exception-safe design

Installation

pip install upd-logger

Quick Start

from upd_logger import Logger

# Initialize
Logger.setup_logging(
    log_dir="my_app_logs",
    write_to_file=True,
    max_log_size=10*1024*1024,  # 10MB
    max_log_age_days=7
)

# Usage
Logger("Application started", "info")
Logger("Important event", "warn")

Full Usage Examples

Basic Configuration

# Console-only logging
Logger.setup_logging(write_to_file=False)

# File logging with custom formats
Logger.setup_logging(
    log_dir="logs"
)

Logging Examples

# Different log levels
Logger("Debug information", "debug")
Logger("Non-critical issue", "warn")
Logger("Critical failure!", "crit")

# Error handling
try:
    risky_operation()
except Exception as e:
    Logger(f"Operation failed: {str(e)}", "error")

Runtime Reconfiguration

# Switch to emergency console-only mode
Logger.setup_logging(write_to_file=False)
Logger("File logging disabled!", "warn")

Configuration Options

Best Practices

1. Initialize early - Call setup_logging() at application startup

2. Use proper levels:

   • debug - Diagnostic info
   • info - Regular operations
   • warn - Unexpected but recoverable
   • error - Failed operations
   • crit - Critical failures

3. Include context in messages:

# Good
Logger(f"User {user_id} failed login (attempt {attempt_count})", "warn")

# Bad
Logger("Something happened", "warn")

Advanced Features

Custom Cleanup Rules

# Keep logs for 1 day or max 1MB
Logger.setup_logging(
    max_log_size=1024*1024,
    max_log_age_days=1
)

Testing Integration

# In tests - disable file logging
Logger.setup_logging(write_to_file=False)
