如何将此AppleScript转换为osascript？

Question

我已经写了一个AppleScript，想把它转换成一个osascript，这样我就可以在启动时使用launchd来运行它。有没有办法将它转换为osascript，或者我必须将整个脚本重写为osascript？如果做不到，是否至少有一种方法可以在终端中将其作为osascript运行？谢谢!

on idle
       tell application "System Events" to ¬
    if exists process "Launchpad" then run script
        tell application "Launchpad"
            delay 0
            tell application "System Events" to keystroke "b" using {control down, option down, command down}
            delay 0
            tell application "System Events" to keystroke "b" using {control down, option down, command down}
            delay 0
            tell application "System Events" to keystroke "b" using {control down, option down, command down}
            delay 0
        end tell
end idle

如果您只需要每秒运行一次或频率较低，则可以将其另存为普通脚本：

tell application "System Events"
    if not (exists process "Launchpad") then return
    repeat 3 times
        keystroke "b" using {control down, option down, command down}
    end repeat
end tell

并使用launchd重复运行该脚本：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC -//Apple Computer//DTD PLIST 1.0//EN
http://www.apple.com/DTDs/PropertyList-1.0.dtd>
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.stackoverflow.11945633</string>
    <key>ProgramArguments</key>
    <array>
        <string>osascript</string>
        <string>/Users/username/Library/Scripts/script.scpt</string>
    </array>
    <key>StartInterval</key>
    <integer>1</integer>
</dict>
</plist>

必须使用launchctl load ~/Library/LaunchAgents/com.stackoverflow.11945633.plist手动加载属性列表。应用更改需要卸载并加载它。

默认情况下，程序在20秒后发送SIGKILL信号。您可以通过添加ExitTimeOut密钥来覆盖超时。参见man launchd.plist。

该脚本实际上并不适用于更改Launchpad背景。Launchpad.app只是一个虚拟的应用程序，当它打开时会立即退出。

如果你只想改变背景样式，你可以用defaults write com.apple.dock springboard-background-filter -int 2; killall Dock来实现。
