在我对您的另一个问题How can I copy result from Calculator.app to the clipboard using AppleScript 的回答的附录的基础上，这是一种在 Calculator 中设置 ⌘V 并设置 Calculator 的方法strong> > 查看 > 小数位数到剪贴板上数字的小数位数。
示例 AppleScript 代码的作用：
当在 Calculator 中按 ⌘V 时，剪贴板的内容被设置为一个变量，如果它包含一个小数点，它将 Calculator > View > Decimal Places menu 设置为数字中的小数位数，然后击键将数字输入计算器 .请注意，keystroking number 可能不需要您设置 小数位数，但我将由您决定.
示例 AppleScript 代码：
set theNumberToType to the clipboard as text
if theNumberToType contains "." then
set theNumberOfDecimalPlaces to count characters ((offset of "." in theNumberToType) + 1) thru -1 of theNumberToType
if theNumberOfDecimalPlaces is greater than 15 then set theNumberOfDecimalPlaces to 15
else
set theNumberOfDecimalPlaces to -1
end if
tell application "Calculator" to activate
tell application "System Events"
if theNumberOfDecimalPlaces is greater than -1 then
click (first menu item of menu 1 of menu item "Decimal Places" of menu 1 of menu bar item "View" of menu bar 1 of process "Calculator" whose name is theNumberOfDecimalPlaces)
end if
delay 0.1
keystroke theNumberToType
end tell
上面的示例 AppleScript 代码 保存为 CalculatorSetDecimalPlaces.applescript 在：~/.hammerspoon/Scripts/，就像在我对你其他问题的其他回答。
示例 Lua 代码：
-- Create a hotkey used to trap the command v shortcut and disable it.
-- It will then be enabled/disabled as Calculator is focused/unfocused.
-- When enabled and command v is pressed it runs the AppleScript script.
local applicationCalculatorCommandVHotkey = hs.hotkey.bind({"cmd"}, "V", function()
local asFile = "/.hammerspoon/Scripts/CalculatorSetDecimalPlaces.applescript"
local ok, status = hs.osascript.applescriptFromFile(os.getenv("HOME") .. asFile)
if not ok then
msg = "An error occurred running the CalculatorResultToClipboard script."
hs.notify.new({title="Hammerspoon", informativeText=msg}):send()
end
end)
applicationCalculatorCommandVHotkey:disable()
-- Add the following two line respectively before or after the lines
-- applicationCalculatorEnterHotkey:enable()
-- applicationCalculatorEnterHotkey:disable()
-- in either of the two methods presented in my other answer.
applicationCalculatorCommandVHotkey:enable()
applicationCalculatorCommandVHotkey:disable()
注意事项：
使用示例 Lua 代码，作为编码，⌘V 键盘的行为快捷方式 仅被捕获和修改以触发 示例 AppleScript 代码，而 Calculator 具有焦点。 ⌘V 键盘快捷键应该可以在所有其他应用程序中正常工作。
上面的 example Lua code 从我对您的其他回答中添加到 ~/.hammerspoon/init.lua file其他问题。
示例 Lua 代码和Hammerspoon的API和AppleScript code，如上所示，分别在 macOS Mojave 下使用 Hammerspoon 和 Script Editor 进行了测试> 和 macOS Catalina，将 系统偏好设置 中的 语言和地区 设置设置为 English (US) - Primary 并且可以正常工作对我来说没有问题1。

仅使用 Lua 更新，不使用 AppleScript
以下示例 Lua 代码从这个答案和中都消除了AppleScript的使用代码 在您其他相关问题的其他答案中。
覆盖现有的代码，将其复制并粘贴到您的~/.hammerspoon/init.lua 文件中，保存并从运行Reload Config >Hammerspoon 菜单在菜单栏上。
我已经执行了 cmets 中讨论的所有各种操作和计算，并且这个新的代码没有出现任何问题。希望这将消除您遇到的任何问题。
由于它还必须处理 AppleScript 代码，因此它也应该运行得更快。
请注意，按照编码，它不会自动重新加载配置文件，因为这不是必需的。
