User .XCompose file not loaded #3827

Closed crater2150 closed 3 years ago

crater2150 commented 3 years ago

Describe the bug Compose sequences defined in my user compose file (~/.XCompose) do not work in kitty for me. Other programs (e.g. my browser) recognize them. I tried with the following minimal ~/.XCompose, which should insert an α when typing Compose, *, a:

<Multi_key> <asterisk> <a>      : "α"  U03B1       # GREEK SMALL LETTER ALPHA

Compose sequences defined in the locale's XCompose on the other hand do work, e.g. Compose, s, s inserts ß.

I tried with kitty 0.21.1 from Voidlinux and current master built from git.

To Reproduce Steps to reproduce the behavior:

  1. Create above compose file in ~/.XCompose
  2. Run kitty (I used kitty --debug-keyboard --config NONE
  3. Press Compose, *, a
  4. Kitty shows *a instead of α

kitty uses libxkbcommon for loading compose files, you will need to ask its maintainers why it doesn't like your ~/.XCompose If you run kitty from another terminal you will likely see an error about it printed out.

There is no error message regarding the compose file, if I just launch kitty without typing anything, there is no output besides

Loading new XKB keymaps

I don't think I have any other programs, which use libxkbcommon directly instead of through Qt/GTK, so I can't test, if they work. For anyone interested, I reported this as xkbcommon/libxkbcommon#254.
