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.
