如何防止 hammerspoon 热键覆盖其他应用程序中的热键？

Question

我正在寻找仅在 Google Chrome:

中可用的特定热键

hs.hotkey.bind({"cmd"}, "0", function()
  if hs.window.focusedWindow():application():name() == 'Google Chrome' then
    hs.eventtap.keyStrokes("000000000000000000")
  end
end)

此方法的问题是热键将无法在其他应用程序上使用。例如。 CMD+0 不会触发 Discord 中的 Reset Zoom 命令。

我该如何预防？

Answer 1

hs.hotkey API doesn't provide functionality to be able to propagate the captured keydown event. The hs.eventtap API 可以，但使用它需要监视每个 keyDown 事件。

我会指出一个有点相关的内容 GitHub issue:

If you're wanting the key combo to do something for most applications, but not for a few specific ones, you're better off using a window filter or application watcher and enabling/disabling the hotkey(s) when the active application changes.

换句话说，对于您要实现的目标，建议您使用 hs.window.filter API 在进入应用程序时启用热键绑定，并在离开应用程序时禁用它，即类似于：

-- Create a new hotkey
local yourHotkey = hs.hotkey.new({ "cmd" }, "0", function()
    hs.eventtap.keyStrokes("000000000000000000")
end)

-- Initialize a Google Chrome window filter
local GoogleChromeWF = hs.window.filter.new("Google Chrome")

-- Subscribe to when your Google Chrome window is focused and unfocused
GoogleChromeWF
    :subscribe(hs.window.filter.windowFocused, function()
        -- Enable hotkey in Google Chrome
        yourHotkey:enable()
    end)
    :subscribe(hs.window.filter.windowUnfocused, function()
        -- Disable hotkey when focusing out of Google Chrome
        yourHotkey:disable()
    end)
