Hi, Let me assess situation more verbosely.

The upstream of glfw doesn't support GLFW_IM_MODULE. The vendored copy of glfw in the popular kitty supports GLFW_IM_MODULE and kitty upstream still advises not to enable this input method support as the default setting. So we decided not to enable it from im-config Since fcitx5 uses the same protocol as ibus, documented proposed workaround was to set GLFW_IM_MODULE=ibus for both ibus case and fcitx5 case. fcitx4 isn't supported and no proposed setting. > > > But SDL_IM_MODULE can be found in sdl2 code. > > > Ref: > > > > https://github.com/libsdl-org/SDL/blob/120c76c8/src/core/linux/SDL_ime.c#L46-L49 The upstream of sdl in Debian has been supporting fcitx via SDL_IM_MODULE for some time. No popular programs in Debian　used modern sdl2 so the support of fcitx via SDL_IM_MODULE was never raised nor addressed in im-config. It should have been and is a valid feature addition case for im-config. > ... > 2. Changing sdl2 upstream takes too long to propagate.

The vendored copy of sdl2 in the popular non-Debian DOTA finally got updated and now support of fcitx (fcitx4?) via SDL_IM_MODULE is a desirable feature. So there is significant desire to set up fcitx for sdl2 from the user. We know from glfw discussion, fcitx4 and fcitx5 uses different protocol. (fcitx5==ibus) My question is what is the correct value for SDL_IM_MODULE which works with Debian's sdl2 and DOTA's sdl2?. ibus --> no setting for SDL_IM_MODULE fcitx (fcitx4) --> SDL_IM_MODULE=fcitx fcitx5 --> SDL_IM_MODULE=fcitx5 or SDL_IM_MODULE=ibus Please propose your patch and explain your setting Regards, Osamu
