control n’est pas reconnu par kitty sous macos

[brabalan]

Dans la discussion de ce bug kovidgoyal/kitty#7841, il semblerait que ergo‑l soit en cause :

I am saying your custom layout is SENDING TEXT for ctrl-a so kitty will treat that key press as generating text not as a control key. As it should.

Je ne suis pas sûr de comprendre ce que cela veut dire, mais visiblement il y a un problème avec le keylayout généré (tout fonctionne quand je passe en qwerty système).

Ok, donc je viens de sortir d'une débable similaire sur Arch Linux.
Est-ce que macos utilise xkeyboard-config ?!!!

---

Turn out, it's not a problem with Kitty. It comes from xkeyboard-config where Hyper and the "dead key" (ISO_Level5_Latch) are mapped together.

Il s'avère que le problème ne vient pas de Kitty mais de xkeyboard-config où la touche Hyper et "la touche morte" (ISO_Level5_Latch) sont mappées ensemble.

En résumé, c'est du coté d'xkeyboard-config et bientôt mergé. J'ai compilé la version prochaine et ça marche.

J'attendrais la release 2.44 (prévue pour le 5 février, bientôt dans les dépôt d'Arch).

Sur Arch Linux, on utilise les paquets AUR pour des cas comme ça. Voici le mien :

pkgname=xkeyboard-config-git
pkgver=2.43_ache
pkgrel=1
pkgdesc="X keyboard configuration files ache"
arch=($CARCH)
license=('custom')
url="https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config"
makedepends=(git xorg-xkbcomp libxslt python meson git)
conflicts=(${pkgname%-git} xkbdata xkbdata-git)
provides=(${pkgname%-git} xkbdata xkbdata-git)
replaces=(xkbdata-git)
source=("git+https://gitlab.freedesktop.org/wismill/xkeyboard-config.git#branch=modifiers/optional-mod3-mappings")
sha256sums=('SKIP')

pkgver() {
  cd ${pkgname%-git}
  _ver="$(git describe | sed 's/^[^[:digit:]]*-//;s/-[^-]*$//;s/^v//;s/-.*//')"
  echo "${_ver}_r$(git rev-list --count HEAD).g$(git rev-parse --short HEAD)"
}

build() {
  cd ${pkgname%-git}
  arch-meson build \
    -D xkb-base="/usr/share/X11/xkb" \
    -D compat-rules=true \
    -D xorg-rules-symlinks=true


  # Print config
  # meson configure -C build

  meson compile -C build
 }
 
 package() { 
  cd ${pkgname%-git}
  DESTDIR="$pkgdir" meson install -C build

  install -m755 -d "${pkgdir}/var/lib/xkb"
  install -m755 -d "${pkgdir}/usr/share/licenses/${pkgname}"
  # install -m644 ${pkgname}-${pkgver}/COPYING "${pkgdir}/usr/share/licenses/${pkgname}/"
}

Kitty en mode debug donne ça :

On constate qu'Hyper n'apparait plus et que ISO_Level5_Latch est de retour ! Aussi, ç est correctement envoyée au terminal.
