get current active keyboard layout(language) in linux -

in c/c++ program want know language user going type. mean language id displayed in corner of task bar. en or ru or zh or fr or it.

i know how list of possible layout:

$ setxkbmap -query | grep layout

output:

layout:     us,ru

but how know 1 selected right now? (for current window)

setxkbmap -print isn't helpful in case, first idea. have found little tool, easy compile

sudo apt-get install git mkdir -p `~/src` cd `~/src` git clone https://github.com/nonpop/xkblayout-state.git  cd xkblayout-state make

now can run command ./xkblayout-state current layout, e.g.

./xkblayout-state print "%n"                           german%

or list installed layouts

./xkblayout-state print "%n" german english english

^{in case without trailing %. have expected that, because have not added \n.}
