virtual_keyboard.lua
-- Dependency: xdotool
--
-- Usage:
-- 1. Save as "virtual_keyboard.lua" in ~/.config/awesome/
-- 2. Add a virtual_keyboard for every screen:
-- awful.screen.connect_for_each_screen(function(s)
-- ...
-- local virtual_keyboard = require("virtual_keyboard")
-- s.virtual_keyboard = virtual_keyboard:new({ screen = s } )
-- ...
-- end)
-- 3. Toggle by using: awful.screen.focused().virtual_keyboard:toggle()
