GTK and Qt applications can switch its IM.
But I think there is no way to do from shell script.

If we implement GTK IM module/Qt IM module/xim proxy, it could do that.

our current discussion focus on to replace xim method w/
chameleon-tongue, and the most critical mission for all such
technology is to properly set:

export XMODIFIERS="@im=fcitx"
export GTK_IM_MODULE=fcitx
export GTK3_IM_MODULE=fcitx
export QT_IM_SWITCHER=imsw-multi
export QT_IM_MODULE=fcitx
export QT4_IM_MODULE=fcitx

to make input method framework take over users' input.

I thought GTK3_* and QT4_* are superfluous nowadays as Gtk3 and Qt4
look at GTK_* and QT_* variables as well?

and all such
applications/ways can only set input method globally once at system
boot (I might be wrong about this).

Not at boot, but at each X session / login.

after Xorg was started, there's no
way to swich input method frameworks. My question is, is there such
thing like:


works. So when an application is started, it'll actually fetch
GTK_IM_MODULE by running a script, which can check process of input
method framework and /etc/sysconfig/inputmethod or something to find
user preference. So you can switch from fcitx to ibus without the need
to restart/logout.

I guess a wrapper like

. /usr/lib/input-method/profile.d/auto/env
exec "$@"

would work. But it's doubtful whether such a dynamic switch is really
demanded. Even with this mechanism, an application needs to be
restart in anyway. If a DE has some session management, it can
restart itself and restores the session after refreshing the
IM-related environment variables.

Or we have to write an special im module named "imfd" or something to
dynamically set and load input method frameworks?

BTW, I think along with shell scripts, ruby is also a good
alternative, because every openSUSE installation have YaST and ruby

Yes, but I don't think there won't be so complicated even in bash.
Let's see.
