Wayland 支持 + +当前版本仅支持 X11。在 Wayland 环境下： + +- 需要运行在 XWayland 兼容层 +- 或设置 `GDK_BACKEND=x11` 环境变量 +- 原生 Wayland 支持正在开发中 + +#### 4. Display 连接复用 + +本库已优化 Linux 实现，在热键注册期间保持 X11 Display 连接： + +``` +注册时： XOpenDisplay → XGrabKey → 保持连接 +事件循环： 使用相同连接 → XNextEvent +注销时： XUngrabKey → XCloseDisplay +``` + +这大幅降低了资源开销和延迟。 + +### Windows + +#### 1. 热键按下事件 + +Windows 使用 `RegisterHotKey` API 注册系统级热键，通过 `WM_HOTKEY` 消息接收按键事件。 + +**实现细节**： +- 使用 `PeekMessageW` (Unicode) 轮询消息队列 +- 10ms 轮询间隔，CPU 占用约 0.3-0.5% +- `isKeyDown` 状态标志防止重复触发 +- 按下事件延迟通常 < 10ms + +#### 2. 热键释放事件 + +Windows `RegisterHotKey` API 不提供键释放通知，本库使用 `GetAsyncKeyState` 轮询检测： + +```go +// 检测键释放（每 10ms 检查一次） +if isKeyDown && GetAsyncKeyState(key) == 0 { + keyupIn <- struct{}{} + isKeyDown = false +} +``` + +**特性**： +- 释放检测延迟：通常 10-20ms +- 仅在按键按下后激活检测 +- 依赖于 `GetAsyncKeyState` 的精度 + +#### 3. 持续按住行为 + +Windows 在持续按住热键时会重复发送 `WM_HOTKEY` 消息。本库通过 `isKeyDown` 标志防止同一次按住重复触发 Keydown 事件。 + +如果需要防止快速连续按键，建议在应用层添加防抖： + +```go +var lastTrigger time.Time +debounceInterval := 100 * time.Millisecond + +for { + <-hk.Keydown() + now := time.Now() + if now.Sub(lastTrigger) < debounceInterval { + continue // 忽略 + } + lastTrigger = now + // 处理事件... +} +``` + +#### 4. 系统保留热键 + +某些热键被 Windows 系统保留，无法注册： + +- `Win+L`：锁定屏幕 +- `Ctrl+Alt+Del`：安全选项 +- `Alt+Tab`：切换窗口 +- `Alt+F4`：关闭窗口 +- `Win+D`：显示桌面 + +尝试注册这些热键会返回 `ErrFailedToRegister`。 + +#### 5. 热键冲突 + +如果热键已被其他应用注册，`RegisterHotKey` 会失败。常见冲突来源： + +- 游戏快捷键 +- 输入法快捷键 +- 快捷键管理工具（AutoHotkey 等） +- 其他全局热键应用 + +返回错误为 `ErrFailedToRegister`（Windows 不区分冲突和其他失败）。 + +#### 6. 线程模型 + +- 热键注册和消息循环运行在同一个 OS 线程上 +- 使用 `runtime.LockOSThread()` 确保线程亲和性 +- 不要求是主线程（与 macOS 不同） +- `ph.funcs` channel 用于在事件循环线程中执行注册/注销操作 + +--- + +### macOS + +#### 1. 主事件循环要求 + +macOS 的 Carbon 事件 API 通过 GCD（Grand Central Dispatch）调度到主队列执行。 + +**GUI 应用（Wails、Cocoa 等）**： +- ✅ 框架已自动管理主事件循环 +- ✅ 热键功能开箱即用，无需额外配置 + +**纯 CLI 应用**： +- ⚠️ 需要手动启动 macOS 运行循环 +- 参见下文"macOS 纯 CLI 应用示例" + +#### 2. 权限问题 + +macOS 可能需要辅助功能权限。如果热键无法注册，请检查： + +``` +系统偏好设置 → 安全性与隐私 → 隐私 → 辅助功能 +``` + +将你的应用添加到允许列表。 + +#### 3. Carbon vs Cocoa + +当前实现使用 Carbon API（稳定且兼容性好）。未来版本可能会迁移到更现代的 Cocoa API。 + +#### 4. macOS 纯 CLI 应用示例 + +如果你的应用**不是 GUI 应用**，需要启动主事件循环。 + +**最简单的方法：使用 darwin.Init()（推荐）** + +```go +//go:build darwin + +package main + +import ( + "fmt" + "voidraft/internal/common/hotkey" + "voidraft/internal/common/hotkey/darwin" +) + +func main() { + // 使用 darwin.Init 启动主事件循环 + darwin.Init(run) +} + +func run() { + hk := hotkey.New([]hotkey.Modifier{hotkey.ModCmd, hotkey.ModShift}, hotkey.KeyA) + if err := hk.Register(); err != nil { + fmt.Printf("注册失败: %v\n", err) + return + } + defer hk.Close() + + fmt.Println("热键已注册: Cmd+Shift+A") + + for { + <-hk.Keydown() + fmt.Println("热键触发！") + } +} +``` + +**高级用法：使用 darwin.Call() 在主线程执行操作** + +```go +darwin.Init(func() { + hk := hotkey.New(...) + hk.Register() + + for { + <-hk.Keydown() + // 在主线程执行 macOS API 调用 + darwin.Call(func() { + // 例如调用 Cocoa/AppKit API + fmt.Println("这段代码在主线程执行") + }) + } +}) +``` + +**注意**： +- GUI 应用无需调用 `darwin.Init()`，框架已处理 +- `darwin.Call()` 用于需要主线程的特定 macOS API +- 热键注册本身已通过 `dispatch_get_main_queue()` 自动调度到主线程 + +## 🔬 架构设计 + +### 目录结构 + +``` +internal/common/hotkey/ +├── hotkey.go # 统一的公共 API +├── hotkey_windows.go # Windows 平台适配器 +├── hotkey_darwin.go # macOS 平台适配器 +├── hotkey_linux.go # Linux 平台适配器 +├── hotkey_nocgo.go # 非 CGO 平台占位符 +├── windows/ +│ ├── hotkey.go # Windows 核心实现 +│ └── mainthread.go # Windows 线程管理 +├── darwin/ +│ ├── hotkey.go # macOS 核心实现 +│ ├── hotkey.m # Objective-C/Carbon 代码 +│ └── mainthread.go # macOS 线程管理 +└── linux/ + ├── hotkey.go # Linux 核心实现 + ├── hotkey.c # X11 C 代码 + └── mainthread.go # Linux 线程管理 +``` + +### 设计原则 + +1. **平台隔离**：每个平台的实现完全独立，通过构建标签分离 +2. **统一接口**：所有平台提供相同的 Go API +3. **资源安全**：自动资源管理，防止泄漏 +4. **并发安全**：所有公共方法都是线程安全的 +5. **错误透明**：标准化错误类型，便于处理 + +### 事件流程 + +``` +用户按键 + ↓ +操作系统捕获 + ↓ +平台特定 API（Win32/X11/Carbon） + ↓ +C/Objective-C 回调 + ↓ +Go channel（类型转换） + ↓ +用户应用代码 +``` + +### 并发模型 + +``` +主 Goroutine 事件 Goroutine 转换 Goroutine + │ │ │ +Register() ────启动──────→ eventLoop() │ + │ │ │ + │ 等待 OS 事件 │ + │ │ │ + │ ├────发送────→ 类型转换 │ + │ │ │ │ + │ │ └─→ Keydown()/Keyup() + │ │ │ +Unregister() ──停止信号──→ 退出循环 │ + │ │ │ + └──────等待清理─────────────┴──────────────────────────┘ +``` + +## 📊 性能特性 + +### 资源占用 + +- **内存**：每个热键约 1-2 KB（包括 goroutines、channels、CGO handles） +- **Goroutines**：每个热键 3 个 + - 1 个事件循环 goroutine + - 2 个通道转换 goroutine (interface{} → Event) +- **CPU**： + - **Windows**：10ms 轮询，约 0.3-0.5% CPU（单核，空闲时） + - **Linux**：事件驱动 (`XNextEvent` 阻塞)，几乎无 CPU 占用 + - **macOS**：事件驱动 (GCD 调度)，几乎无 CPU 占用 +- **线程**： + - 每个热键 1 个 OS 线程（通过 `runtime.LockOSThread()` 锁定） + +### 延迟 + +**按下事件 (Keydown)**： +- Windows: < 10ms（取决于轮询间隔） +- Linux: < 10ms（X11 事件延迟） +- macOS: < 5ms（Carbon 事件延迟） + +**释放事件 (Keyup)**： +- Windows: 10-20ms（`GetAsyncKeyState` 轮询检测） +- Linux: < 15ms（X11 KeyRelease 事件） +- macOS: < 10ms（Carbon 事件延迟） + +### 使用建议 + +1. **资源管理**： + - 使用 `defer hk.Close()` 确保资源释放 + - 不需要时及时调用 `Unregister()` 或 `Close()` + - 避免频繁创建/销毁热键对象 + +2. **事件处理**： + - 热键事件处理应快速返回，避免阻塞 channel + - 复杂逻辑应在新 goroutine 中处理 + - 考虑应用层防抖（特别是 Linux AutoRepeat） + +3. **错误处理**： + - 始终检查 `Register()` 返回的错误 + - 使用 `errors.Is()` 判断错误类型 + - 处理热键冲突场景（提供备用方案或用户提示） + +4. **平台差异**： + - Windows Keyup 事件有轻微延迟（正常现象） + - Linux 可能需要防抖处理 AutoRepeat + - macOS CLI 应用需要启动主事件循环 + +## 🐛 故障排查 + +### Linux: "Failed to initialize the X11 display" + +**问题**：无法连接到 X11 显示服务器 + +**解决方案**： +```bash +# 检查 DISPLAY 环境变量 +echo $DISPLAY + +# 如果为空，设置它 +export DISPLAY=:0 + +# 或使用虚拟显示 +Xvfb :99 -screen 0 1024x768x24 & +export DISPLAY=:99 +``` + +### macOS: 热键不触发 + +**问题**：注册成功但热键无响应 + +**解决方案**： +1. 检查辅助功能权限（见上文） +2. 如果是纯 CLI 应用，确保启动了主运行循环（见上文示例） +3. 检查其他应用是否占用了该热键 + +### Windows: ErrFailedToRegister + +**问题**：热键注册失败 + +**可能原因**： +1. 热键已被其他应用占用（AutoHotkey、游戏、输入法等） +2. 尝试注册系统保留热键（Win+L、Ctrl+Alt+Del 等） +3. 热键 ID 冲突（极少见） + +**解决方案**： +1. 检查任务管理器，关闭可能冲突的应用 +2. 使用不同的热键组合 +3. 在应用中提供热键自定义功能，让用户选择可用组合 +4. 提供友好的错误提示，说明热键被占用 + +**调试方法**： +```go +if err := hk.Register(); err != nil { + if errors.Is(err, hotkey.ErrFailedToRegister) { + log.Printf("热键注册失败: %v", err) + log.Printf("提示：该热键可能已被其他应用使用") + // 尝试备用热键... + } +} +``` + +### Windows: Keyup 事件延迟 + +**问题**：释放事件比预期晚 10-20ms + +**原因**：Windows API 限制，`RegisterHotKey` 不提供释放通知，需要轮询检测。 + +**这是正常行为**： +- 10ms 轮询间隔导致的固有延迟 +- 对大多数应用场景影响很小 +- 如果需要精确的释放时机，考虑使用底层键盘钩子（复杂度更高） + +### 所有平台: Keyup 事件丢失 + +**问题**：只收到 Keydown，没有 Keyup + +**可能原因**： +1. 在接收 Keyup 前调用了 `Unregister()` +2. 通道缓冲区满（不太可能，使用了无缓冲通道） +3.
