rofi: IMEs (fcitx5, ibus) not working in rofi

[imsuck]

Nixpkgs version

• Unstable (25.05)

Describe the bug

rofi disregards IMEs like fcitx5, ibus, and their keybinds even though they should be supported.

Steps to reproduce

1. Have fcitx5 installed and running (with some plugins like fcitx5-mocz).
2. Run: nix shell nixpkgs#rofi.
3. Execute: rofi -show drun.
4. Type some words or try to change input methods via keybindings.

Expected behaviour

IME should work like in other programs' text field.

Additional context

Arch's rofi package works as expected (is this appropriate?)

Hello @imsuck,
I've never used IMEs but looking at how it was implemented in rofi I opened this PR: #387135

👉 Could you try it and let me know if it's enough to make it work for you?

You'll need to use rofi with an override like this:

pkgs.rofi.override {
  # replace rofi-unwrapped with a package that supports IMEs
  rofi-unwrapped = pkgs.rofi-unwrapped.override { imeSupport = true; };
}

Where pkgs is a pinned version of nixpkgs that includes my PR.

#387135 was just merged (thank you @teto!), the rofi package now supports IMEs by default.
