🚀 Quick Start

As a Library

use luna::{Luna,LunaConfig};// Initialize LUNA with default configurationletmut luna = luna::init()?;// Analyze current screenlet elements = luna.analyze_current_screen()?;println!("Found {} UI elements", elements.len());// Find specific elementslet buttons = luna::find_buttons_on_screen()?;for button in buttons {println!("Button at ({:.0}, {:.0}) - {:.1}% confidence", button.bounds.x, button.bounds.y, button.confidence *100.0);}

As an Application

# Run with default configuration
cargo run --bin luna
# Run in test mode
cargo run --bin luna -- --test
# Run without overlay
cargo run --bin luna -- --headless

Quick Functions

use luna;// One-shot screen analysislet elements = luna::analyze_current_screen()?;// Find specific UI elementslet buttons = luna::find_buttons_on_screen()?;let text_boxes = luna::find_text_boxes_on_screen()?;// Quick screenshotlet image = luna::quick_screenshot()?;

🔧 Advanced Usage

Custom Configuration

use luna::{LunaConfig, core::SafetyLevel};letmut config = LunaConfig::default();
config.enable_overlay = false;
config.safety_level = SafetyLevel::High;
config.capture_fps = 60;letmut luna = luna::init_with_config(config)?;

Screen Analysis Pipeline

use luna::{Luna, vision};letmut luna = Luna::new(config)?;
luna.initialize()?;// Capture screenlet image = luna.capture_screen()?;// Analyze for UI elementslet elements = luna.analyze_screen(&image)?;// Process resultsfor element in elements {match element.element_type{
luna::ElementType::Button => {println!("Found button: {:.1}% confidence", element.confidence *100.0);}
luna::ElementType::TextBox => {println!("Found text box at ({:.0}, {:.0})", element.bounds.x, element.bounds.y);}
_ => {}}}

Overlay System

use luna::{OverlayManager,Color,Rectangle,Point};letmut overlay = OverlayManager::default();// Add highlightslet bounds = Rectangle::new(100.0,100.0,200.0,50.0);
overlay.add_highlight(bounds,Color::rgb(255,0,0),Some("Important".to_string()));// Add labels
overlay.add_label(Point::new(50.0,75.0),"Click here".to_string(),Color::rgb(255,255,255));// Update animations
overlay.update_animations(std::time::Duration::from_millis(16));

Safe Input Handling

use luna::input::{InputController,BasicSafetyChecker,InputAction,ActionType};let safety_checker = Box::new(BasicSafetyChecker::new());letmut input = InputController::new(safety_checker);let action = InputAction{action_type:ActionType::Click{button: luna::input::MouseButton::Left},target: luna::input::Target{x:100,y:200,element_type:Some("button".to_string()),},timestamp: std::time::Instant::now(),};// Execute with automatic safety validationmatch input.execute_action(action){Ok(()) => println!("Action executed safely"),Err(e) => println!("Action blocked: {}", e),}

🔮 Migration from Original LUNA

Breaking Changes

1. Import Paths: Module structure has changed

   // Olduse luna::ai::CLIPModel;// Newuse luna::ai::VisionAI;

2. Configuration Format: Simplified configuration structure

   // Oldlet config = LunaConfig{ai_model_path:"path/to/model",// ...};// Newlet config = LunaConfig{safety_level:SafetyLevel::Medium,// ...};

3. API Simplification: Streamlined function signatures

   // Old
   luna.analyze_screen_with_model(&image,&model_config)?;// New
   luna.analyze_screen(&image)?;

Migration Guide

1. Update Dependencies: Remove heavy ML dependencies from Cargo.toml
2. Update Imports: Change module paths to new structure
3. Simplify Configuration: Use new configuration format
4. Test Functionality: Verify all features work with new implementation

Compatibility Shim

For easier migration, a compatibility layer is available:

// Enable compatibility modeuse luna::compat::v1;// Use old-style APIlet elements = v1::analyze_screen_legacy(&image)?;
