Logging Implementation Summary

Overview

Comprehensive logging has been added to all Python files in the YouTube CLI project.

Changes Made

1. Logs Directory

• Created /Users/user/Projects/youtube-cli/logs/ directory
• Added logs/ to .gitignore (already present)

2. Logging Configuration

All Python files now have:

• Log file: ~/.config/youtube_cli/logs/app.log
• Rotation: 10MB max, keep 5 backups
• Level: DEBUG (file), INFO (console)
• Format: %(asctime)s | %(name)s | %(levelname)s | %(message)s

3. Files Modified

/Users/user/Projects/youtube-cli/youtube_cli/main.py

• Added logging and RotatingFileHandler imports
• Added module-level logger: logger = logging.getLogger(__name__)
• Replaced all console.print() statements with appropriate logger calls:
  • logger.debug() for verbose debugging info
  • logger.info() for normal operations
  • logger.warning() for warnings
  • logger.error() for errors
  • logger.exception() for exceptions (includes traceback)

Key logging additions:

• Search operations
• Download operations
• Archive operations
• Configuration loading
• Network share operations
• Error handling with full context

/Users/user/Projects/youtube-cli/youtube_tui/app.py

• Added logging imports and configuration
• Added module-level logger
• Added logging initialization in main() function

/Users/user/Projects/youtube-cli/youtube_tui/services/download_manager.py

• Added logging imports and configuration
• Added module-level logger
• Replaced console.print() with:
  • logger.warning() for cancellations
  • logger.error() for errors

/Users/user/Projects/youtube-cli/youtube_tui/services/youtube.py

• Added logging imports and configuration
• Added module-level logger
• Replaced self.console.print() with logger.error() for service errors

/Users/user/Projects/youtube-cli/youtube_tui/services/queue.py

• Added logging imports and configuration
• Added module-level logger
• Replaced console.print() with logger.warning() for queue operations

/Users/user/Projects/youtube-cli/app.py (REST API)

• Added logging imports and configuration
• Added module-level logger
• Added logging initialization in module scope

4. Logging Levels Used

Level	Usage	Example
DEBUG	Detailed debugging info	Download directory paths
INFO	Normal operations	Search queries, download starts, completions
WARNING	Non-critical issues	Invalid inputs, skipped operations
ERROR	Errors	Failed downloads, missing dependencies
CRITICAL	Critical failures	Not used (reserved for severe issues)

5. Benefits

1. Production Monitoring: Full visibility into application behavior
2. Troubleshooting: Detailed logs with timestamps and context
3. Performance Tracking: Log rotation prevents disk space issues
4. Debugging: Both file and console output for development
5. Consistency: Same logging approach across all modules

Usage

View Logs in Real-Time

tail -f ~/.config/youtube_cli/logs/app.log

Search Logs

grep "ERROR" ~/.config/youtube_cli/logs/app.log
grep "WARNING" ~/.config/youtube_cli/logs/app.log

Log File Location

• Logs are stored in: ~/.config/youtube_cli/logs/app.log
• Old logs are automatically rotated and archived

Testing

To verify logging works:

1. Run the CLI: python -m youtube_cli "test query"
2. Run the TUI: python youtube_tui/app.py
3. Run the API: python app.py
4. Check logs: cat ~/.config/youtube_cli/logs/app.log

Notes

• The RotatingFileHandler ensures log files don't grow indefinitely
• Console output is limited to INFO level for cleaner terminal output
• File output captures all DEBUG level messages for thorough logging
• All exceptions are logged with full tracebacks using logger.error()
