How to add a keyboard layout indicator widget in Awesome WM

At first you must install the SKB. Package for Arch Linux are here.

 

Then add to code in rc.lua it lines:

--keyboard layout indicator

function get_layout()
    local filedescriptor = io.popen("skb a")
    local value = filedescriptor:read()
    filedescriptor:close()
    return value
end

keylayout = widget({type = 'textbox', name="keylayout", align = 'right'})

After it you must append "keylayout" to  topwibox[s].widgets

And add hook to last lines of config:

awful.hooks.timer.register(1,  function() keylayout.text = get_layout() end)

where 1 is an update time of the indicator.
