Launch System Settings with macOS Ventura using Hammerspoon

So, Hammerspoon is a thing.

I’m trying it out a bit. I didn’t at first realize how this brand of LUA works, since it seems to be different from the Renoise API LUA code.

But I got this working:

  hs.hotkey.bindSpec({ { "shift", "cmd"}, "," },
    function()
      hs.application.launchOrFocus("System Settings")
    end
  )

This takes your regular Shift-CMD-, and boots up System Settings — and in case it is already running, brings the focus to that.

I didn’t quite yet dig deeper into whether a specific page of System Settings could be brought up, as that would be pretty good, but there’s always next time, right?

No. The time is now. So, there’s a really useful page, which lets you find some additional deeplinks for System Settings, and therefore, this, brings you to Software Update:

open "x-apple.systempreferences:com.apple.Software-Update-Settings.extension"

Now, the real question is, what’s the method for Hammerspoon to boot up these types of deeplinks? Cos it isn’t hs.application.launchOrFocus.

.. Ok, after a very frustrating evening, decided to call it a night and switch approaches. First try and make it work with AppleScript.

This works in AppleScript:

tell application "System Settings"
 activate
end tell
tell application "System Settings"
 reveal pane id "com.apple.Software-Update-Settings.extension" 
end tell

Not sure why it needs two tells, but at least it works. Well, here’s how it looks like with Hammerspoon. For some reason, this is very slow!

  hs.hotkey.bindSpec({ { "ctrl", "cmd", "alt"}, "," },
    function()
      hs.osascript.applescript([[tell application "System Settings" to reveal pane id "com.apple.Software-Update-Settings.extension"
        tell application "System Settings" to activate]])
    end
  )

If anyone knows how to make this faster, please let me know?

EDIT: This is how you get it to be faster:

  hs.hotkey.bindSpec({ { "ctrl", "cmd", "alt"}, "," },
    function()
      local url = 'x-apple.systempreferences:com.apple.Software-Update-Settings.extension'
      local handler = 'com.apple.systempreferences'
      hs.urlevent.openURLWithBundle(url, handler)
    end
  )

The advice was provided in this comment in this ticket: https://github.com/Hammerspoon/hammerspoon/issues/3457#issuecomment-1503588230

Thanks everyone!
