Sway: Add input-method support

[emersion]

[cedws]

What is meant by this, what does it entail? I have been using fcitx for a while now for input methods.

@c-edw https://github.com/wayland-project/wayland-protocols/blob/master/unstable/input-method/input-method-unstable-v1.xml

More specifically, implement the wlroots type for the v2 that protocol in sway.

Is this the v2 of the protocol?

[emersion]

Yes. The wlroots side already has an implementation.

Hello, after some retries, I was able find a way to use fcitx-mozc with sway (japanese input).

It's not 100% but seems ok to everyday use. Hope this helps.
どーもありがとう御座います。

How come v2 isn't part of the wayland-protocols repository? Is it controversial?

[emersion]

It's still being reviewed. It's also missing an implementation of some parts of the protocol.

I updated https://github.com/helionmelion/sway-fcitx-workaround

Details of my home desktop:
using Arch Linux
u̶s̶i̶n̶g̶ ̶S̶D̶D̶M̶ ̶d̶i̶s̶p̶l̶a̶y̶ ̶m̶a̶n̶a̶g̶e̶r̶
using GDM display manager
sway windows manager
zsh shell
using JAPANESE NATIVE KEYBOARD jp(OADG109A)
I want Japanese and Brazilian Portuguese input method.

Update: this time I created the file ~/.config/environment.d/wayland.conf and put this:

export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx
fcitx -r
export _JAVA_AWT_WM_NONREPARENTING=1
export XDG_SESSION_TYPE=wayland
export GDK_BACKEND=wayland
export CLUTTER_BACKEND=wayland
export QT_QPA_PLATFORM=wayland-egl
export SDL_VIDEODRIVER=wayland
export QT_WAYLAND_FORCE_DPI=physical
export QT_WAYLAND_DISABLE_WINDOWDECORATION=1

and on ~/.config/sway/config

input "1:1:AT_Translated_Set_2_keyboard" {
xkb_layout "jp,br"
xkb_model "jp(OADG109A)"
xkb_options "grp:rctrl_rshift_toggle,grp_led:scroll"
xkb_numlock enabled
}
exec_always fcitx -r

This two config files are sourced and will execute fcitx.

Must be noted that toggle key combinations here and fcitx must not be the same. So I choose rctrl here and default ctrl+space in fcitx/mozc.
The combination rctrl+rshift will change jp to pt-br layout and lit scroll lock.

@emersion I want to work on adding support for this protocol; Do you think it's worth it even though it's still "being reviewed"? Are there going to be any drastic changes to it? Are there even any clients using the v2 protocol?

[emersion]

There's work for this in https://github.com/swaywm/sway/pull/4740

Pioneers are those who do not ask those questions, and just do it.
