    Message : rules: Fix wild card handling The handling of wild card `*` is different in libxkbfile and X server: wild card matches empty strings for model and option but not for layout nor variant, while in libxkbcommon wild cards always match empty strings. See: - https://gitlab.freedesktop.org/xorg/lib/libxkbfile/-/blob/bf985c68acb1244f51ec91414532a2347fbc1c4c/src/maprules.c#L687 - https://gitlab.freedesktop.org/xorg/lib/libxkbfile/-/blob/bf985c68acb1244f51ec91414532a2347fbc1c4c/src/maprules.c#L712 The difference of handling between the components is unfortunately not documented, but we should follow the behavior of the original implementations for consistency. - Fixed by implementing the same behavior than libxkbfile. - Added tests and fixed failing tests. - Improve the documentation of rules to highlight the special behavior.

  • rules: Fix handling of wild card `*` to match the behavior of `libxkbfile`.
Previously `*` would match any value, even empty one. Now:
- For `model` and `options`: *always* match.
- For `layout` and `variant`: match any *non-empty* value.
