A few quick snippets:

  Hammerspoon popup alert:
    hs.alert.show("Hello, world!")

  MacOS notification:
    hs.notify.new({title="Hammerspoon", informativeText="Hello, world!"}):send()

  Using a spoon:
    hs.loadSpoon("AClock")
    spoon.AClock:init()
    hs.hotkey.bind(meh, "c", function() spoon.AClock:toggleShow() end)

TODO list:

* turn bluetooth back on (e.g., after sleep)
  * https://github.com/toy/blueutil

* consider moving window management out of Moom and into here
  * http://www.hammerspoon.org/docs/hs.screen.html
