Hi, The Intelligent Input Bus (IBus, pronounced as I-Bus) is an input method (IM) framework for multilingual input in Unix-like operating-systems.
The ibus package can work via XIM but it is non-optimal. For GTK or QT applications, it is desirable to have corresponding libraries installed and enabled for processing keyboard inputs. Currently ibus package sets to Recommends: ibus-gtk | ibus-qt4 | libqt5gui5, ibus-gtk3 | ibus-qt4 | libqt5gui5, im-config So if ibus-gtk and ibus-qt4 are installed, ibus will not bother pulling in: * ibus-gtk3 for GTK3 * libqt5gui5 for QT5 What is needed is like: Recommends: ((ibus-gtk, ibus-gtk3 ) | ibus-qt4 | libqt5gui5 ) , im-config This is because GTK_IM_MODULE values are shared by both gtk2 and gtk3 behavior of ibus. Unless ibus-gtk, ibus-gtk3 are both installed, GTK_IM_MODULE=xim. QT/QT5 doesn't suffer since they use different environment variables. But () is not used for the logical purpose in recommends, I think. So to solve Bug#921541 https://bugs.debian.org/921541 , I am thinking to change ibus to be: Recommends: ibus-gtk , ibus-gtk3, ibus-qt4 , libqt5gui5 , im-config After all, if user chose not to install any one of recommends, he should know the possible limitations. The negative side effect is too much libraries to be installed for many desktop system. Unless I get better idea, I will do this recommend all approach. Any idea? Regards, Osamu
