-- @module keygrabber
---
-- Grab keyboard input and read pressed keys, calling a callback function at
-- each keypress, until `keygrabber.stop` is called.
-- The callback function receives three arguments:
-- <ul>
-- <li>a table containing modifiers keys</li>
-- <li>a string with the pressed key</li>
-- <li>a string with either "press" or "release" to indicate the event type.</li>
-- </ul>
-- @param callback A callback function as described above.
-- @function run
-- @usage The following function can be bound to a key, and will be used to
-- resize a client using keyboard.
--
-- function resize(c)
-- keygrabber.run(function(mod, key, event)
-- if event == "release" then return end
--
-- if key == 'Up' then awful.client.moveresize(0, 0, 0, 5, c)
-- elseif key == 'Down' then awful.client.moveresize(0, 0, 0, -5, c)
-- elseif key == 'Right' then awful.client.moveresize(0, 0, 5, 0, c)
-- elseif key == 'Left' then awful.client.moveresize(0, 0, -5, 0, c)
-- else keygrabber.stop()
-- end
-- end)
-- end
--- Stop grabbing the keyboard.
-- @function stop
--- Check if the keygrabber is running.
-- @return A boolean value, true if running, false otherwise.
-- @function isrunning
