+# Canvas Library Migration Guide
+
+## Overview
+
+This guide covers the migration from the legacy canvas library structure to the new clean, modular architecture. The new design separates core canvas functionality from autocomplete features, providing better type safety and maintainability.
+
+## Key Changes
+
+### 1. **Modular Architecture**
+```
+# Old Structure (LEGACY)
+src/
+├── state.rs              # Mixed canvas + autocomplete
+├── actions/edit.rs       # Mixed concerns
+├── gui/render.rs         # Everything together
+└── suggestions.rs        # Legacy file
+
+# New Structure (CLEAN)
+src/
+├── canvas/               # Core canvas functionality
+│   ├── state.rs         # CanvasState trait only
+│   ├── actions/edit.rs  # Canvas actions only
+│   └── gui.rs           # Canvas rendering
+├── autocomplete/         # Rich autocomplete features
+│   ├── state.rs         # AutocompleteCanvasState trait
+│   ├── types.rs         # SuggestionItem, AutocompleteState
+│   ├── actions.rs       # Autocomplete actions
+│   └── gui.rs           # Autocomplete dropdown rendering
+└── dispatcher.rs         # Action routing
+```
+
+### 2. **Trait Separation**
+- **CanvasState**: Core form functionality (navigation, input, validation)
+- **AutocompleteCanvasState**: Optional rich autocomplete features
+
+### 3. **Rich Suggestions**
+Replaced simple string suggestions with typed, rich suggestion objects.
+
+## Migration Steps
+
+### Step 1: Update Import Paths
+
+**Find and Replace these imports:**
+
+```rust
+# OLD IMPORTS
+use canvas::CanvasState;
+use canvas::CanvasAction;
+use canvas::ActionContext;
+use canvas::HighlightState;
+use canvas::CanvasTheme;
+use canvas::ActionDispatcher;
+use canvas::ActionResult;
+
+# NEW IMPORTS
+use canvas::canvas::CanvasState;
+use canvas::canvas::CanvasAction;
+use canvas::canvas::ActionContext;
+use canvas::canvas::HighlightState;
+use canvas::canvas::CanvasTheme;
+use canvas::dispatcher::ActionDispatcher;
+use canvas::canvas::ActionResult;
+```
+
+**Complex imports:**
+```rust
+# OLD
+use canvas::{CanvasAction, ActionDispatcher, ActionResult};
+
+# NEW
+use canvas::{canvas::CanvasAction, dispatcher::ActionDispatcher, canvas::ActionResult};
+```
+
+### Step 2: Clean Up State Implementation
+
+**Remove legacy methods from your CanvasState implementation:**
+
+```rust
+impl CanvasState for YourFormState {
+    // Keep all the core methods:
+    fn current_field(&self) -> usize { /* ... */ }
+    fn get_current_input(&self) -> &str { /* ... */ }
+    // ... etc
+
+    // ❌ REMOVE these legacy methods:
+    // fn get_suggestions(&self) -> Option<&[String]>
+    // fn get_selected_suggestion_index(&self) -> Option<usize>
+    // fn set_selected_suggestion_index(&mut self, index: Option<usize>)
+    // fn activate_suggestions(&mut self, suggestions: Vec<String>)
+    // fn deactivate_suggestions(&mut self)
+}
+```
+
+### Step 3: Implement Rich Autocomplete (Optional)
+
+**If you want rich autocomplete features:**
+
+```rust
+use canvas::autocomplete::{AutocompleteCanvasState, SuggestionItem, AutocompleteState};
+
+impl AutocompleteCanvasState for YourFormState {
+    type SuggestionData = YourDataType; // e.g., Hit, CustomRecord, etc.
+
+    fn supports_autocomplete(&self, field_index: usize) -> bool {
+        // Define which fields support autocomplete
+        matches!(field_index, 2 | 3 | 5) // Example: only certain fields
+    }
+
+    fn autocomplete_state(&self) -> Option<&AutocompleteState<Self::SuggestionData>> {
+        Some(&self.autocomplete)
+    }
+
+    fn autocomplete_state_mut(&mut self) -> Option<&mut AutocompleteState<Self::SuggestionData>> {
+        Some(&mut self.autocomplete)
+    }
+}
+```
+
+**Add autocomplete field to your state:**
+```rust
+pub struct YourFormState {
+    // ... existing fields
+    pub autocomplete: AutocompleteState<YourDataType>,
+}
+```
+
+### Step 4: Migrate Suggestions
+
+**Old way (simple strings):**
+```rust
+let suggestions = vec!["John".to_string(), "Jane".to_string()];
+form_state.activate_suggestions(suggestions);
+```
+
+**New way (rich objects):**
+```rust
+let suggestions = vec![
+    SuggestionItem::new(
+        hit1,                                    // Your data object
+        "John Doe (Manager) | ID: 123".to_string(), // What user sees
+        "123".to_string(),                       // What gets stored
+    ),
+    SuggestionItem::simple(hit2, "Jane".to_string()), // Simple version
+];
+form_state.set_autocomplete_suggestions(suggestions);
+```
+
+### Step 5: Update Rendering
+
+**Old rendering:**
+```rust
+// Manual autocomplete rendering
+if form_state.autocomplete_active {
+    render_autocomplete_dropdown(/* ... */);
+}
+```
+
+**New rendering:**
+```rust
+// Canvas handles everything
+use canvas::canvas::render_canvas;
+
+let active_field_rect = render_canvas(f, area, form_state, theme, edit_mode, highlight_state);
+
+// Optional: Rich autocomplete (if implementing AutocompleteCanvasState)
+if form_state.is_autocomplete_active() {
+    if let Some(autocomplete_state) = form_state.autocomplete_state() {
+        canvas::autocomplete::render_autocomplete_dropdown(
+            f, f.area(), active_field_rect.unwrap(), theme, autocomplete_state
+        );
+    }
+}
+```
+
+### Step 6: Update Method Calls
+
+**Replace legacy method calls:**
+```rust
+# OLD
+form_state.deactivate_suggestions();
+
+# NEW - Option A: Add your own method
+impl YourFormState {
+    pub fn deactivate_autocomplete(&mut self) {
+        self.autocomplete_active = false;
+        self.autocomplete_suggestions.clear();
+        self.selected_suggestion_index = None;
+    }
+}
+form_state.deactivate_autocomplete();
+
+# NEW - Option B: Use rich autocomplete trait
+form_state.deactivate_autocomplete(); // If implementing AutocompleteCanvasState
+```
+
+## Benefits of New Architecture
+
+### 1. **Clean Separation of Concerns**
+- Canvas: Form rendering, navigation, input handling
+- Autocomplete: Rich suggestions, dropdown management, async loading
+
+### 2. **Type Safety**
+```rust
+// Old: Stringly typed
+let suggestions: Vec<String> = vec!["user1".to_string()];
+
+// New: Fully typed with your domain objects
+let suggestions: Vec<SuggestionItem<UserRecord>> = vec![
+    SuggestionItem::new(user_record, display_text, stored_value)
+];
+```
+
+### 3. **Rich UX Capabilities**
+- **Display vs Storage**: Show "John Doe (Manager)" but store user ID
+- **Loading States**: Built-in spinner/loading indicators
+- **Async Support**: Designed for async suggestion fetching
+- **Display Overrides**: Show friendly text while storing normalized data
+
+### 4. **Future-Proof**
+- Easy to add new autocomplete features
+- Canvas features don't interfere with autocomplete
+- Modular: Use only what you need
+
+## Advanced Features
+
+### Display Overrides
+Perfect for foreign key relationships:
+
+```rust
+// User selects "John Doe (Manager) | ID: 123"
+// Field stores: "123" (for database)
+// User sees: "John Doe" (friendly display)
+
+impl CanvasState for FormState {
+    fn get_display_value_for_field(&self, index: usize) -> &str {
+        if let Some(display_text) = self.link_display_map.get(&index) {
+            return display_text.as_str(); // Shows "John Doe"
+        }
+        self.inputs().get(index).map(|s| s.as_str()).unwrap_or("") // Shows "123"
+    }
+    
+    fn has_display_override(&self, index: usize) -> bool {
+        self.link_display_map.contains_key(&index)
+    }
+}
+```
+
+### Progressive Enhancement
+Start simple, add features when needed:
+
+```rust
+// Week 1: Basic usage
+SuggestionItem::simple(data, "John".to_string());
+
+// Week 5: Rich display
+SuggestionItem::new(data, "John Doe (Manager)".to_string(), "John".to_string());
+
+// Week 10: Store IDs, show names
+SuggestionItem::new(user, "John Doe (Manager)".to_string(), "123".to_string());
+```
+
+## Breaking Changes Summary
+
+1. **Import paths changed**: Add `canvas::` or `dispatcher::` prefixes
+2. **Legacy suggestion methods removed**: Replace with rich autocomplete or custom methods
+3. **No more simple suggestions**: Use `SuggestionItem` for typed suggestions
+4. **Trait split**: `AutocompleteCanvasState` is now separate and optional
+
+## Troubleshooting
+
+### Common Compilation Errors
+
+**Error**: `no method named 'get_suggestions' found`
+**Fix**: Remove legacy method from `CanvasState` implementation
+
+**Error**: `no 'CanvasState' in the root`
+**Fix**: Change `use canvas::CanvasState` to `use canvas::canvas::CanvasState`
+
+**Error**: `trait bound 'FormState: CanvasState' is not satisfied`
+**Fix**: Make sure your state properly implements the new `CanvasState` trait
+
+### Migration Checklist
+
+- [ ] Updated all import paths
+- [ ] Removed legacy methods from CanvasState implementation
+- [ ] Added custom autocomplete methods if needed
+- [ ] Updated suggestion usage to SuggestionItem
+- [ ] Updated rendering calls
+- [ ] Tested form functionality
+- [ ] Tested autocomplete functionality (if using)
+
+## Example: Complete Migration
+
+**Before:**
+```rust
+use canvas::{CanvasState, CanvasAction};
+
+impl CanvasState for FormState {
+    fn get_suggestions(&self) -> Option<&[String]> { /* ... */ }
+    fn deactivate_suggestions(&mut self) { /* ... */ }
+    // ... other methods
+}
+```
+
+**After:**
+```rust
+use canvas::canvas::{CanvasState, CanvasAction};
+use canvas::autocomplete::{AutocompleteCanvasState, SuggestionItem};
+
+impl CanvasState for FormState {
+    // Only core canvas methods, no suggestion methods
+    fn current_field(&self) -> usize { /* ... */ }
+    fn get_current_input(&self) -> &str { /* ... */ }
+    // ... other core methods only
+}
+
+impl AutocompleteCanvasState for FormState {
+    type SuggestionData = Hit;
+    
+    fn supports_autocomplete(&self, field_index: usize) -> bool {
+        self.fields[field_index].is_link
+    }
+    
+    fn autocomplete_state(&self) -> Option<&AutocompleteState<Self::SuggestionData>> {
+        Some(&self.autocomplete)
+    }
+    
+    fn autocomplete_state_mut(&mut self) -> Option<&mut AutocompleteState<Self::SuggestionData>> {
+        Some(&mut self.autocomplete)
+    }
+}
+```
+
+This migration results in cleaner, more maintainable, and more powerful code!

+# Canvas 🎨
+
+A reusable, type-safe canvas system for building form-based TUI applications with vim-like modal editing.
+
+## ✨ Features
+
+- **Type-Safe Actions**: No more string-based action names - everything is compile-time checked
+- **Generic Design**: Implement `CanvasState` once, get navigation, editing, and suggestions for free
+- **Vim-Like Experience**: Modal editing with familiar keybindings
+- **Suggestion System**: Built-in autocomplete and suggestions support
+- **Framework Agnostic**: Works with any TUI framework or raw terminal handling
+- **Async Ready**: Full async/await support for modern Rust applications
+- **Batch Operations**: Execute multiple actions atomically
+- **Extensible**: Custom actions and feature-specific handling
+
+## 🚀 Quick Start
+
+Add to your `Cargo.toml`:
+
+```toml
+cargo add canvas
+```
+
+Implement the `CanvasState` trait:
+
+```rust
+use canvas::prelude::*;
+
+#[derive(Debug)]
+struct LoginForm {
+    current_field: usize,
+    cursor_pos: usize,
+    username: String,
+    password: String,
+    has_changes: bool,
+}
+
+impl CanvasState for LoginForm {
+    fn current_field(&self) -> usize { self.current_field }
+    fn current_cursor_pos(&self) -> usize { self.cursor_pos }
+    fn set_current_field(&mut self, index: usize) { self.current_field = index; }
+    fn set_current_cursor_pos(&mut self, pos: usize) { self.cursor_pos = pos; }
+
+    fn get_current_input(&self) -> &str {
+        match self.current_field {
+            0 => &self.username,
+            1 => &self.password,
+            _ => "",
+        }
+    }
+
+    fn get_current_input_mut(&mut self) -> &mut String {
+        match self.current_field {
+            0 => &mut self.username,
+            1 => &mut self.password,
+            _ => unreachable!(),
+        }
+    }
+
+    fn inputs(&self) -> Vec<&String> { vec![&self.username, &self.password] }
+    fn fields(&self) -> Vec<&str> { vec!["Username", "Password"] }
+    fn has_unsaved_changes(&self) -> bool { self.has_changes }
+    fn set_has_unsaved_changes(&mut self, changed: bool) { self.has_changes = changed; }
+}
+```
+
+Use the type-safe action dispatcher:
+
+```rust
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let mut form = LoginForm::new();
+    let mut ideal_cursor = 0;
+
+    // Type a character - compile-time safe!
+    ActionDispatcher::dispatch(
+        CanvasAction::InsertChar('h'),
+        &mut form,
+        &mut ideal_cursor,
+    ).await?;
+
+    // Move to next field
+    ActionDispatcher::dispatch(
+        CanvasAction::NextField,
+        &mut form,
+        &mut ideal_cursor,
+    ).await?;
+
+    // Batch operations
+    let actions = vec![
+        CanvasAction::InsertChar('p'),
+        CanvasAction::InsertChar('a'),
+        CanvasAction::InsertChar('s'),
+        CanvasAction::InsertChar('s'),
+    ];
+
+    ActionDispatcher::dispatch_batch(actions, &mut form, &mut ideal_cursor).await?;
+
+    Ok(())
+}
+```
+
+## 🎯 Type-Safe Actions
+
+The Canvas system uses strongly-typed actions instead of error-prone strings:
+
+```rust
+// ✅ Type-safe - impossible to make typos
+ActionDispatcher::dispatch(CanvasAction::MoveLeft, &mut form, &mut cursor).await?;
+
+// ❌ Old way - runtime errors waiting to happen
+execute_edit_action("move_left", key, &mut form, &mut cursor).await?;
+execute_edit_action("move_leftt", key, &mut form, &mut cursor).await?; // Oops!
+```
+
+### Available Actions
+
+```rust
+pub enum CanvasAction {
+    // Character input
+    InsertChar(char),
+    
+    // Deletion
+    DeleteBackward,
+    DeleteForward,
+    
+    // Movement
+    MoveLeft, MoveRight, MoveUp, MoveDown,
+    MoveLineStart, MoveLineEnd,
+    MoveWordNext, MoveWordPrev,
+    
+    // Navigation
+    NextField, PrevField,
+    MoveFirstLine, MoveLastLine,
+    
+    // Suggestions
+    SuggestionUp, SuggestionDown,
+    SelectSuggestion, ExitSuggestions,
+    
+    // Extensibility
+    Custom(String),
+}
+```
+
+## 🔧 Advanced Features
+
+### Suggestions and Autocomplete
+
+```rust
+impl CanvasState for MyForm {
+    fn get_suggestions(&self) -> Option<&[String]> {
+        if self.suggestions.is_active {
+            Some(&self.suggestions.suggestions)
+        } else {
+            None
+        }
+    }
+
+    fn handle_feature_action(&mut self, action: &CanvasAction, _context: &ActionContext) -> Option<String> {
+        match action {
+            CanvasAction::InsertChar('@') => {
+                // Trigger email suggestions
+                let suggestions = vec![
+                    format!("{}@gmail.com", self.username),
+                    format!("{}@company.com", self.username),
+                ];
+                self.activate_suggestions(suggestions);
+                None // Let generic handler insert the '@'
+            }
+            CanvasAction::SelectSuggestion => {
+                if let Some(suggestion) = self.suggestions.get_selected() {
+                    *self.get_current_input_mut() = suggestion.clone();
+                    self.deactivate_autocomplete();
+                    Some("Applied suggestion".to_string())
+                }
+                None
+            }
+            _ => None,
+        }
+    }
+}
+```
+
+### Custom Actions
+
+```rust
+fn handle_feature_action(&mut self, action: &CanvasAction, _context: &ActionContext) -> Option<String> {
+    match action {
+        CanvasAction::Custom(cmd) => match cmd.as_str() {
+            "uppercase" => {
+                *self.get_current_input_mut() = self.get_current_input().to_uppercase();
+                Some("Converted to uppercase".to_string())
+            }
+            "validate_email" => {
+                if self.get_current_input().contains('@') {
+                    Some("Email is valid".to_string())
+                } else {
+                    Some("Invalid email format".to_string())
+                }
+            }
+            _ => None,
+        },
+        _ => None,
+    }
+}
+```
+
+### Integration with TUI Frameworks
+
+Canvas is framework-agnostic and works with any TUI library:
+
+```rust
+// Works with crossterm (see examples)
+// Works with termion
+// Works with ratatui/tui-rs
+// Works with cursive
+// Works with raw terminal I/O
+```
+
+## 🏗️ Architecture
+
+Canvas follows a clean, layered architecture:
+
+```
+┌─────────────────────────────────────┐
+│           Your Application          │
+├─────────────────────────────────────┤
+│         ActionDispatcher            │  ← High-level API
+├─────────────────────────────────────┤
+│     CanvasAction (Type-Safe)        │  ← Type safety layer
+├─────────────────────────────────────┤
+│        Action Handlers              │  ← Core logic
+├─────────────────────────────────────┤
+│        CanvasState Trait            │  ← Your implementation
+└─────────────────────────────────────┘
+```
+
+## 🤝 Why Canvas?
+
+### Before Canvas
+```rust
+// ❌ Error-prone string actions
+execute_action("move_left", key, state)?;
+execute_action("move_leftt", key, state)?; // Runtime error!
+
+// ❌ Duplicate navigation logic everywhere
+impl MyLoginForm { /* navigation code */ }
+impl MyConfigForm { /* same navigation code */ }
+impl MyDataForm { /* same navigation code again */ }
+
+// ❌ Manual cursor and field management
+if key == Key::Tab {
+    current_field = (current_field + 1) % fields.len();
+    cursor_pos = cursor_pos.min(current_input.len());
+}
+```
+
+### With Canvas
+```rust
+// ✅ Type-safe actions
+ActionDispatcher::dispatch(CanvasAction::MoveLeft, state, cursor)?;
+// Typos are impossible - won't compile!
+
+// ✅ Implement once, use everywhere
+impl CanvasState for MyForm { /* minimal implementation */ }
+// All navigation, editing, suggestions work automatically!
+
+// ✅ High-level operations
+ActionDispatcher::dispatch_batch(actions, state, cursor)?;
+```

+```rust
+// Legacy support (deprecated)
+execute_edit_action("move_left", key, state, cursor).await?;
+
+// New type-safe way
+ActionDispatcher::dispatch(CanvasAction::MoveLeft, state, cursor).await?;
+```
+
+## 🧪 Testing
+
+```bash
+# Run all tests
+cargo test
+
+# Run specific example
+cargo run --example simple_login
+
+# Check type safety
+cargo check
+```
+
+## 📋 Requirements
+
+- Rust 1.70+
+- Terminal with cursor support
+- Optional: async runtime (tokio) for examples
+
+## 🤔 FAQ
+
+**Q: Does Canvas work with [my TUI framework]?**  
+A: Yes! Canvas is framework-agnostic. Just implement `CanvasState` and handle the key events.
+
+**Q: Can I extend Canvas with custom actions?**  
+A: Absolutely! Use `CanvasAction::Custom("my_action")` or implement `handle_feature_action`.
+
+**Q: Is Canvas suitable for complex forms?**  
+A: Yes! See the `config_screen` example for validation, suggestions, and multi-field forms.
+
+**Q: How do I migrate from string-based actions?**  
+A: Canvas provides backwards compatibility. Migrate incrementally using the type-safe APIs.

+## How Canvas Library Custom Functionality Works
+
+### 1. **The Canvas Library Calls YOUR Custom Code First**
+
+When you call `ActionDispatcher::dispatch()`, here's what happens:
+
+```rust
+// Inside canvas library (canvas/src/actions/edit.rs):
+pub async fn execute_canvas_action<S: CanvasState>(
+    action: CanvasAction,
+    state: &mut S,
+    ideal_cursor_column: &mut usize,
+) -> Result<ActionResult> {
+    // 1. FIRST: Canvas library calls YOUR custom handler
+    if let Some(result) = state.handle_feature_action(&action, &context) {
+        return Ok(ActionResult::HandledByFeature(result)); // YOUR code handled it
+    }
+
+    // 2. ONLY IF your code returns None: Canvas handles generic actions
+    handle_generic_canvas_action(action, state, ideal_cursor_column).await
+}
+```
+
+### 2. **Your Extension Point: `handle_feature_action`**
+
+You add custom functionality by implementing `handle_feature_action` in your states:
+
+```rust
+// In src/state/pages/auth.rs
+impl CanvasState for LoginState {
+    // ... other methods ...
+
+    fn handle_feature_action(&mut self, action: &CanvasAction, context: &ActionContext) -> Option<String> {
+        match action {
+            // Custom login-specific actions
+            CanvasAction::Custom(action_str) if action_str == "submit_login" => {
+                if self.username.is_empty() || self.password.is_empty() {
+                    Some("Please fill in all required fields".to_string())
+                } else {
+                    // Trigger login process
+                    Some(format!("Logging in user: {}", self.username))
+                }
+            }
+            
+            CanvasAction::Custom(action_str) if action_str == "clear_form" => {
+                self.username.clear();
+                self.password.clear();
+                self.set_has_unsaved_changes(false);
+                Some("Login form cleared".to_string())
+            }
+
+            // Custom behavior for standard actions
+            CanvasAction::NextField => {
+                // Custom validation when moving between fields
+                if self.current_field == 0 && self.username.is_empty() {
+                    Some("Username cannot be empty".to_string())
+                } else {
+                    None // Let canvas library handle the normal field movement
+                }
+            }
+
+            // Let canvas library handle everything else
+            _ => None,
+        }
+    }
+}
+```
+
+### 3. **Multiple Ways to Add Custom Functionality**
+
+#### A) **Custom Actions via Config**
+```toml
+# In config.toml
+[keybindings.edit]
+submit_login = ["ctrl+enter"]
+clear_form = ["ctrl+r"]
+```
+
+#### B) **Override Standard Actions**
+```rust
+fn handle_feature_action(&mut self, action: &CanvasAction, context: &ActionContext) -> Option<String> {
+    match action {
+        CanvasAction::InsertChar('p') if self.current_field == 1 => {
+            // Custom behavior when typing 'p' in password field
+            Some("Password field - use secure input".to_string())
+        }
+        _ => None, // Let canvas handle normally
+    }
+}
+```
+
+#### C) **Context-Aware Logic**
+```rust
+fn handle_feature_action(&mut self, action: &CanvasAction, context: &ActionContext) -> Option<String> {
+    match action {
+        CanvasAction::MoveDown => {
+            // Custom logic based on current state
+            if context.current_field == 1 && context.current_input.len() < 8 {
+                Some("Password should be at least 8 characters".to_string())
+            } else {
+                None // Normal field movement
+            }
+        }
+        _ => None,
+    }
+}
+```
+
+## The Canvas Library Philosophy
+
+**Canvas Library = Generic behavior + Your extension points**
+
+- ✅ **Canvas handles**: Character insertion, cursor movement, field navigation, etc.
+- ✅ **You handle**: Validation, submission, clearing, app-specific logic
+- ✅ **You decide**: Return `Some(message)` to override, `None` to use canvas default
+
+## Summary
+
+You **don't communicate with the library elsewhere**. Instead:
+
+1. **Canvas library calls your code first** via `handle_feature_action`
+2. **Your code decides** whether to handle the action or let canvas handle it
+3. **Canvas library handles** generic form behavior when you return `None`
