Greetings, I've been using plain XMonad for some time (not combined with KDE/GNome). Currently, I'm switching between keyboard layouts simply by a key combination globally: [ ((modMask , xK_Scroll_Lock ), spawn "setxkbmap -layout us ; xmodmap ~/.Xmodmap") , ((modMask .|. shiftMask, xK_Scroll_Lock), spawn "setxkbmap -layout cz ; xmodmap ~/.Xmodmap") ] However that's a bit inconvenient. For many windows (i.e. browser, terminal) I need to keep the US layout most of the time. I need the localized layout only for text editors in 99% of cases. And I switch windows/workspaces a lot, so I have to switch the layouts manually almost every time I switch. Ideally I'd like to achieve: - By pressing the key combination I set some kind of flag for the currently focused window. - XMonad calls the spawn "setxkbmap ..." commands automatically according to the flags when window focus changes. How to do that (if it's possible)? Thanks for help. (Bonus: Manage the flags externally by some kind of command from scripts.)
