### 可选：启用"撤回通知带原文"
|
||||
|
||||
完成基础安装后，在终端前台运行消息监听，撤回通知就会带上原文。
|
||||
完成基础安装后，安装消息监听服务，撤回通知就会带上原文（当前只支持私聊，群聊暂不支持）。
|
||||
|
||||
```bash
|
||||
./patch.sh --monitor # 前台运行消息监听，Ctrl+C 退出
|
||||
./patch.sh --monitor-install # 安装（后台自动运行，开机自启）
|
||||
./patch.sh --monitor-status # 查看状态
|
||||
./patch.sh --monitor-uninstall # 卸载
|
||||
```
|
||||
|
||||
监听运行期间，收到的消息会被缓存；对方撤回时通知自动展示消息原文。
|
||||
安装后无需手动操作。微信启动时自动开始监听消息、微信关闭后自动收尾、下次启动再次跟随。
|
||||
|
||||
不运行此命令也不影响防撤回主功能，撤回通知降级为不带原文。
|
||||
不安装也不影响防撤回主功能，撤回通知降级为不带原文。
|
||||
|
||||
> **已知限制**：部分群聊消息因内部对象结构差异，可能无法缓存原文，撤回时会降级为不带原文的通知。私聊消息和大部分群聊消息可正常获取原文。

- **聊天框内无撤回提示**：由于微信 4.x 的架构限制（C++ 实现 + 符号 strip + 数据库加密），无法在聊天界面内插入系统消息。替代方案为 macOS 系统通知。

- **撤回通知原文需 monitor 在跑**：消息原文功能依赖前台 `./patch.sh --monitor` 监听消息。不运行时撤回通知降级为不带原文。

- **monitor 运行时微信会被 lldb attach**：性能影响极小（每条消息触发约 1ms 断点回调）。如果不需要原文功能，不启动 monitor 即可。
