hammerspoon config for mac

说明

Hammerspoon 是一款革命性的 macOS 桌面自动化工具，它将系统级 API 与灵活的 Lua 脚本引擎相结合。通过编写自定义的 Lua 脚本，您可以对系统进行强大的控制。
程序员一般的工作习惯都是两个显示屏幕，两个浏览器窗口，多个编程编辑器窗口，再加至少一个即时通讯工具,或者还有一个终端console。如果使用系统快捷键切换不够精确，用鼠标又不方便，特别是需要把光标移到扩展的显示屏的时候。Hammerspoon作为一个专业的macos自动化工具可以带领很大的方便。

• 如果快捷键不起作用，切换输入法为英文.
• 以下快捷键，里面有“+”号，表示分段，不代表键盘，先按前面部分，在1秒内再按后面部分。
• vscode版本:1.80.1. 安装了golang,vim插件。macos 12.6.
• https://github.com/Hammerspoon/hammerspoon

环境

• Macos 14
• Hammerspoon 1.0.0

安装

• 官方连接 https://github.com/Hammerspoon/hammerspoon
• 参考说明，下载dmg文件安装或者brew安装均可。

默认功能快捷键

• ⌘+, 为tab键上面的按键。弹出来一个选择窗口,如下:
• 再按数字或者字母，即可切换到对应的窗口。

自定义功能快捷键

• 点击右上角🔨图标，选择 “open config",可以自己写lua脚本。再次选择 “reload config”即可生效。
• lua脚本功能可参考github官网.
• 以下是我个人实现的一些功能，比如鼠标光标在主显示屏和扩展屏之间切换, vscode多个窗口循环切换等。
  • 两个全屏 VSCode 窗口 = 两个独立的 macOS Space；
  • macOS 不提供任何 API（也不允许 AppleScript）激活另一个全屏 App 窗口；
  • tell application “Code” to activate 只会激活 当前所在的 Space；
  • 所以，想要多开vscode,必须在配置文件中 加上 “window.nativeFullScreen”: false 。设置后，vscode左上角的全屏按钮会变成+号。
