Plugin System Architecture

The application uses a modular plugin system for parsing different metadata formats:

# Base parser interface
class ParserPluginInterface:
    @staticmethod
    def detect(metadata): pass
    
    @staticmethod  
    def parse(metadata): pass

Key Components

1. Plugin Manager: Handles dynamic loading of parser plugins
2. Statistics Tracker: Manages usage analytics and data persistence
3. GUI Factory: Provides consistent UI component creation
4. Configuration Manager: Handles settings and preferences
5. Error Handler: Provides comprehensive error management
6. Logger: Centralized logging with file and console output

🐛 Troubleshooting

Common Issues & Solutions

Application Won't Start

• Symptom: Executable doesn't launch or crashes immediately
• Solution: Use development build to see console output
• Check: Ensure all dependencies are included in distribution folder

Missing Dependencies Error

• Symptom: ImportError messages for PyQt5, PIL, or other modules
• Solution: Use provided executables or install from requirements.txt
• Command: pip install -r requirements.txt

WebP Metadata Not Extracted

• Symptom: WebP images show no metadata
• Solution: Ensure webpmux.exe is in application directory
• Check: Verify WebP file actually contains metadata

Statistics Not Loading

• Symptom: Statistics tab shows no data
• Solution: Go to Library tab and load a folder first
• Note: Statistics are built from processed images

Performance Issues

• Symptom: Slow startup or response
• Solution: Check log files for detailed performance metrics
• Optimization: Use production build for better performance

Debug Mode

For verbose debugging output:

# Set debug environment and run
set DEBUG=1
MetaPicPick_Dev.exe

Log Files

Check application logs for detailed error information:

• Location: logs/metapicpick.log
