Question: mac layout change watcher

[alex-enchi]

Hi all

Do you know is there a good method to be notified on layout change on macos, aside of checking with interval for
defaults read ~/Library/Preferences/com.apple.HIToolbox.plist AppleSelectedInputSources

Ideally I want to set specific layer on when changing layout and interval does not sound like a best option

Best

I'm not super familiar with macOS, but I think this will require some Swift / ObjectiveC code to subscribe to system's notifications.

Wouldn't it be easier to have a script (Apple script or any automation tool) that you invoke with a key shortcut that:

1. Sets or cycles the input method
2. Read the value of AppleSelectedInputSources
3. Sets the layout accordingly to the value with kontroll

I thought about it as well, but it means that layout must be changed only through shortcut.
Recently I tried option with listening for file changes of that plist file, but apparently file is not updated right away.
