Integrating with Hammerspoon

Hammerspoon is a powerful automation utility that includes menu interaction and window management capabilities.

You can bind Hamerspoon actions to its URL handler:

hs.urlevent.bind("someAlert", function(eventName, params)
    hs.alert.show("Received someAlert")
end)

This creates a url handler hammerspoon://someAlert. You can simply put that URL on a line in a Bunch to launch that action.
