🔍 Code Extractor

Orchestrates a comprehensive demonstration of E-Ink LLM hybrid mode capabilities, running three sequential demos showcasing graphics generation, placeholder parsing, and complete hybrid response processing.

Purpose

This async function serves as the main entry point for demonstrating the E-Ink LLM Assistant's hybrid text+graphics mode. It sequentially executes three demos: individual graphics generation, placeholder parsing, and complete hybrid response processing. The function provides user-friendly console output with progress indicators and error handling, and concludes with usage instructions for implementing hybrid mode in production.

Source Code

async def main():
    """Run all demos"""
    print("🚀 E-Ink LLM Hybrid Mode Demonstration")
    print("=" * 60)
    print("This demo showcases the new hybrid text+graphics capabilities")
    print()
    
    try:
        # Demo 1: Individual graphics generation
        graphics = await demo_graphics_generation()
        
        # Demo 2: Placeholder parsing
        demo_placeholder_parsing()
        
        # Demo 3: Complete hybrid response processing
        await demo_hybrid_response()
        
        print("\n" + "=" * 60)
        print("✅ Demo completed successfully!")
        print("\nTo use hybrid mode in your E-Ink LLM Assistant:")
        print("   python main.py --file input.pdf --enable-hybrid-mode")
        print("\nFor more information, see HYBRID_MODE_GUIDE.md")
        
    except Exception as e:
        print(f"\n❌ Demo failed with error: {e}")
        import traceback
        traceback.print_exc()

Return Value

Returns None (implicitly). The function is designed for side effects (console output and demonstration execution) rather than returning values. On success, it prints completion messages and usage instructions. On failure, it prints error messages and stack traces.

Dependencies

• asyncio
• tempfile
• pathlib
• json
• traceback

Required Imports

import asyncio
import tempfile
from pathlib import Path
import json
from graphics_generator import GraphicsGenerator, GraphicSpec, GraphicType
from hybrid_response_handler import HybridResponseHandler
from hybrid_pdf_generator import HybridPDFGenerator

Conditional/Optional Imports

These imports are only needed under specific conditions:

import traceback

Usage Example

import asyncio

async def demo_graphics_generation():
    # Your graphics demo implementation
    return []

def demo_placeholder_parsing():
    # Your placeholder parsing demo
    pass

async def demo_hybrid_response():
    # Your hybrid response demo
    pass

async def main():
    """Run all demos"""
    print("🚀 E-Ink LLM Hybrid Mode Demonstration")
    print("=" * 60)
    print("This demo showcases the new hybrid text+graphics capabilities")
    print()
    
    try:
        graphics = await demo_graphics_generation()
        demo_placeholder_parsing()
        await demo_hybrid_response()
        
        print("\n" + "=" * 60)
        print("✅ Demo completed successfully!")
        print("\nTo use hybrid mode in your E-Ink LLM Assistant:")
        print("   python main.py --file input.pdf --enable-hybrid-mode")
        print("\nFor more information, see HYBRID_MODE_GUIDE.md")
        
    except Exception as e:
        print(f"\n❌ Demo failed with error: {e}")
        import traceback
        traceback.print_exc()

if __name__ == "__main__":
    asyncio.run(main())

Best Practices

• Always run this function using asyncio.run(main()) or await it from another async context
• Ensure all three demo functions (demo_graphics_generation, demo_placeholder_parsing, demo_hybrid_response) are properly defined before calling main()
• The function includes comprehensive error handling with traceback printing for debugging
• Console output uses Unicode emoji characters; ensure terminal supports UTF-8 encoding
• This is a demonstration function and should not be used in production code without modification
• The function expects specific module dependencies to be available; verify all imports resolve correctly
• Consider wrapping the asyncio.run(main()) call in a if __name__ == '__main__': block when using as a script entry point
