> Does anyone know if there is anything similar to Hammerspoon out there?
Did you forget to include some extra constraint? As written, it looks like the answer to your question is "Yes, Hammerspoon."
Sorry, I realize that is unclear. What I was getting at is just if there are any other similar scripting/automation apps out there, perhaps with a different scripting language or other application integrations. I am a newbie in the automation space so I was wondering what other types of apps people may be using.
You may be interested in AppleScript or AutoHotKey.
