-//
-//  Documentation protocol listing all responder chain actions used in TablePro.
-//  This is a reference guide, not implemented by any class directly.
-//
-//  ## Architecture Pattern
-//
-//  TablePro uses three mechanisms for keyboard shortcuts and commands:
-//
-//  1. **Responder Chain** (Apple Standard):
-//     - Standard edit actions: copy, paste, undo, delete, cancelOperation (ESC)
-//     - Context-aware: First responder handles action appropriately
-//     - Commands send via `NSApp.sendAction(#selector(...), to: nil, from: nil)`
-//
-//  2. **@FocusedValue** (Menu/Toolbar → single handler):
-//     - Most menu commands call `MainContentCommandActions` directly
-//     - Toolbar buttons also use `@FocusedValue` for direct calls
-//     - Clean method calls, no global event bus
-//     - Commands are automatically nil (disabled) when no connection is active
-//
-//  3. **AppCommands** (Multi-listener broadcasts only):
-//     - `refreshData` (Sidebar + Coordinator + StructureView)
-//     - Non-menu commands from AppKit views (DataGrid, SidebarView context menus)
-//     - Typed Combine publishers for broadcasts where multiple views respond
-//
-//  ## Example Flow
-//
-//  ```
-//  User presses: Cmd+Delete
-//    ↓
-//  SwiftUI Command: .keyboardShortcut(.delete, modifiers: .command)
-//    ↓
-//  TableProApp: NSApp.sendAction(#selector(delete(_:)), to: nil, from: nil)
-//    ↓
-//  Responder Chain: First Responder (KeyHandlingTableView)
-//    ↓
-//  KeyHandlingTableView: @objc func delete(_ sender: Any?) { ... }
-//  ```
-//
-//  ## Reference Files
-//  - `TableProApp.swift` - SwiftUI Commands that define shortcuts
-//  - `KeyHandlingTableView.swift` - Data grid keyboard handling
-//  - `HistoryPanelView.swift` - SwiftUI history panel (uses onDeleteCommand)
-//  - `EditorTextView.swift` - SQL editor keyboard handling

- ## How to Implement Responder Chain Actions
-
- ### Step 1: Add @objc Method to Your Responder
-
- ```swift
- final class MyTableView: NSTableView {
- override var acceptsFirstResponder: Bool { true }
-
- @objc func delete(_ sender: Any?) {
- // Your delete logic here
- logger.debug("Deleting selected rows")
- }
- }
- ```
-
- ### Step 2: Add Validation (Optional but Recommended)
-
- ```swift
- extension MyTableView: NSUserInterfaceValidations {
- func validateUserInterfaceItem(_ item: NSValidatedUserInterfaceItem) -> Bool {
- switch item.action {
- case #selector(delete(_:)):
- // Enable Delete only when rows are selected
- return !selectedRowIndexes.isEmpty
- default:
- return false
- }
- }
- }
- ```
-
- ### Step 3: Register Command in TableProApp.swift
-
- ```swift
- .commands {
- CommandGroup(after: .newItem) {
- Button("Delete Row") {
- NSApp.sendAction(#selector(TableProResponderActions.delete(_:)),
- to: nil, from: nil)
- }
- .keyboardShortcut(.delete, modifiers: .command)
- }
- }
- ```
-
- ### Step 4: Use interpretKeyEvents for Bare Keys (Optional)
-
- For non-modifier keys (arrows, Return, ESC), use `interpretKeyEvents`:
-
- ```swift
- override func keyDown(with event: NSEvent) {
- interpretKeyEvents([event])
- }
-
- @objc override func moveUp(_ sender: Any?) {
- // Custom up arrow handling
- }
- ```
-
- ## Benefits of Responder Chain
-
- ✅ **Automatic validation** - Menu items enable/disable based on context
- ✅ **No manual routing** - macOS finds the right handler automatically
- ✅ **Standard behavior** - Users expect Cmd+C/V/Z to work everywhere
- ✅ **VoiceOver support** - Accessibility built-in
- ✅ **Easy to extend** - Just add @objc methods, no global event bus
-
- ## Anti-Patterns to Avoid
-
- ❌ **NotificationCenter for commands** - Bypasses validation, hard to debug
- ❌ **Magic keyCode numbers** - Use KeyCode enum instead
- ❌ **performKeyEquivalent for bare keys** - Only for Cmd+ shortcuts
- ❌ **Custom ESC systems** - Use cancelOperation(_:) selector
- ❌ **Manual keyDown switches** - Use interpretKeyEvents + selectors
