Switch keyboard layout programmaticaly

Question

I use three different layouts and looking code to change layout programmaticaly from .bashrc function.

Answer 1

For example, to get the US layout (that is, by the way, excellent for programming; see this question).

In X, try setxkbmap -layout us

In the Linux console, add XKBLAYOUT="us" to /etc/default/keyboard; then run setupcon as superuser. Or, use dpkg-reconfigure keyboard-configuration (also as superuser). You could also use a different map in the console than in X by using KMAP; look in /etc/console-setup/.

This may require some fiddling; possibly, you'd like to write aliases and/or functions in your .bashrc for fast access. If you plan on switching back and forth, I've found that a compose key is a better solution. Unless, of course, you're writing in a totally different alphabet.

Answer 2

It is indeed strange that X11 doesn't provide a standard tool to switch to a given layout (when you define several with setxkbmap).

But I just found a tool that can do it: https://github.com/nonpop/xkblayout-state

With it you can get/set the current layout, either by name or by position in your layout stack.
