Hammerspoon - kitty terminal + dropdown visor (Guake)

init.lua

hs.hotkey.bind({}, "F15", function()
  local app = hs.application.get("kitty")

  if app then
      if not app:mainWindow() then
          app:selectMenuItem({"kitty", "New OS window"})
      elseif app:isFrontmost() then
          app:hide()
      else
          app:activate()
      end
  else
      hs.application.launchOrFocus("kitty")
      app = hs.application.get("kitty")
  end

  app:mainWindow():moveToUnit'[100,50,0,0]'
  app:mainWindow().setShadows(false)
end)

Also I noticed that the positioning of the window doesn't work reliably on first start of Kitty. Here's my modified version of the script.

local app = hs.application.get("kitty")
local didHide = false

if app then
    if not app:mainWindow() then
        app:selectMenuItem({"Shell", "New OS Window"})
    elseif app:isFrontmost() then
        app:hide()
        didHide = true
    else
        app:activate()
    end
else
    hs.application.launchOrFocus("kitty")
    app = hs.application.get("kitty")
end

if not didHide then
  hs.timer.waitUntil(
    function() return app:isFrontmost() end,
    function() app:mainWindow():moveToUnit('[0,0,100,50]', 0) end
  )
end
