Wayland support

[hyuri]

Hi!

Does it work on Wayland, or any plans to add support? I noticed it uses xdotool, which doesn't support Wayland.

[Jiogo18]

I am using it in a Wayland session with no problem (at least none related to Wayland).

xdotool works well for me (only used for ctrl+v). If you don't have it, the paste option will simply be deactivated (tested in a VM), so no problem. https://github.com/alex1701c/EmojiRunner/blob/5aaa24cfad7e7cee7553c532e3b6c77d1ae9798c/src/runner/emojirunner.cpp#L139

If needed, it could be changed to something like wl-paste.

That seems like good idea, I will play around with it!

Hmm, but wl-paste sends it not to the focussed window :(

[Jiogo18]

Giving a closer look at wl-clipboard, it seems that pasting to another window is not a use case, despite what I though, sorry about that.

Rofimoji uses wtype. Unfortunatly, wtype requires https://wayland.app/protocols/virtual-keyboard-unstable-v1 which is not yet available in KDE (KWin 6.0.4 currently).

Using ydotool:

• ydotool type "Hello 🏃!" doesn't work with emojis

• ydotool key 135:1 135:0 (KEY_PASTE)

  • works in firefox by default
  • works in other applications only after adding "Paste" as a custom shortcut for Paste in the system manager or the application settings for konsole (hmm).
  • (works only in firefox when using QProcess startDetached?) run with a delay

    QProcess::startDetached("sh", QStringList{"-c", "sleep 0.2; ydotool key 135:1 135:0"});

• ydotool key 29:1 47:1 47:0 29:0 (KEY_LEFTCTRL KEY_V)

  • works, even in QProcess, but the application must use Ctrl+V as paste shortcut. https://github.com/ReimuNotMoe/ydotool/issues/22#issuecomment-1825023908
  • (doesn't work in KWrite?)

• ydotool key 54:1 110:1 110:0 54:0 (KEY_LEFTSHIFT KEY_INSERT)

  • works, even in QProcess, without changing the settings
  • doesn't work when the application uses the other clipboard (XTerm, the terminal in VSCode)

Side note: xdotool key ctrl+v still works in some applications (e.g. electron apps).

So, lots of possibilities... with a downside to each. wtype may be the way to go if supported. I will try shift+insert for now.

I think that is due to the xwayland stuff ;)

Yeah ... not really sure what to do

I am using Wayland as well, and the AUR package I build uses xdotool (library) and it works fine.

Maybe xdotool gained Wayland support?
