Log Cleaner Pro

A powerful Python utility that provides comprehensive log management capabilities. This dual-purpose tool helps you maintain clean production code by automatically removing logging statements and console outputs from your codebase, while also efficiently managing your log files through automated cleaning and scheduling. It intelligently handles Python logging statements and JavaScript/TypeScript console outputs, supporting both single-line and multi-line statements, alongside sophisticated log file management features for automated retention and cleanup.

Installation

Using pip (Recommended)

You can install the package directly from GitHub:

# Install latest version
pip install git+https://github.com/cypher-o/log_cleaner.git

# Or specify a version
pip install git+https://github.com/cypher-o/log_cleaner.git@v1.0.0

From source

1. Clone this repository:

   git clone https://github.com/cypher-o/log_cleaner.git
   cd log_cleaner

2. Install in development mode:

   pip install -e .

Usage

Basic Command Line Usage

# Start the interactive tool
log-cleaner

# Or using Python's -m flag
python -m log_cleaner

Code Cleanup Examples

Clean logging statements from a specific directory:

python log_cleaner.py --clean-code ./my_project

Clean specific files:

python log_cleaner.py --clean-code ./src/main.py ./src/utils.js

Log File Management Examples

Clean old log entries:

# Clean logs older than 30 days
python log_cleaner.py --clean-logs ./logs --days 30

# Clean logs before specific date
python log_cleaner.py --clean-logs ./logs --before 2024-01-01

Set up automated cleaning:

# Schedule daily cleanup at 2:30 AM
python log_cleaner.py --schedule ./logs --hour 2 --minute 30

# Remove scheduled cleanup
python log_cleaner.py --remove-schedule

Supported Log Formats

The tool supports various log formats including:

• ISO format timestamps:

2024-02-15 10:30:45 INFO Started application

• Unix timestamps:

1644915045 Started backup process

• Custom formats:

[Feb 15 10:30:45 2024] Server started

Supported Code Patterns

Python

# Import statements
import logging
from logging import getLogger

# Logger initialization
logger = logging.getLogger(__name__)
_logger = logging.getLogger()

# Logging statements
logger.info("Message")
logger.error(f"Error: {error}")
_logger.warning(
    f"Warning message with "
    "multiple lines"
)

JavaScript/TypeScript

// Console statements
console.log("Message");
console.error("Error");
console.warn(
    "Multi-line " +
    "warning message"
);

Backup and Recovery

• Backups are stored in a backup directory with timestamps
• Each backup includes:
  • Original files with directory structure preserved
  • Detailed log file of all changes
  • Timestamp-based organization for easy recovery

Examples

Basic Usage

Clean a specific directory:

python log_cleaner.py
# Select "Select a directory"
# Enter: ./my_project

Clean Specific Files

python log_cleaner.py
# Select "Select specific files"
# Enter files one by one:
# ./src/main.py
# ./src/utils.js

Best Practices

1. Always run on version-controlled code
2. Review changes before confirming
3. Enable backups for important files
4. Test after cleaning
5. Schedule automated cleaning during low-traffic periods
6. Monitor disk space usage
7. Set appropriate retention periods

Limitations

• Complex string concatenations may require manual review
• Cannot detect logging statements in string literals or comments
• May require adjustment of patterns for custom log formats
• Scheduled cleaning requires cron daemon to be running
