ryovm starts Ghostty with kitty's --class syntax, which Ghostty rejects #280

Ryoku starts the terminal for ryovm/ryoport with exec "${TERMINAL:-kitty}" --class <name> -e ....
--class NAME with a space is kitty's form. Ghostty wants --class=NAME. With
Ghostty set as the terminal, every ryovm action opens Ghostty's config error
window and the class is never applied.

Versions

• ryoku-desktop 0.75.3.r3968.gcfd8899-3
• ghostty 1.3.1-2.2
• Hyprland 0.56.2, CachyOS, kernel 7.2.x
• Ryoku terminal setting: desktop.apps.terminal = ghostty

What appears

Ghostty's "Configuration Errors" window:

cli1:class: value required
cli2:ryoport-ssh: invalid field

Repro

ghostty --class ryoport-ssh -e sleep 20      dialog appears
ghostty --class=ryoport-ssh -e sleep 20      no dialog

Class the window ends up with, read back with hyprctl clients:

kitty   --class ryoport-ssh     ryoport-ssh
ghostty --class ryoport-ssh     com.mitchellh.ghostty, dialog shown
ghostty --class=ryoport-ssh     com.mitchellh.ghostty, logs "invalid 'class' in config, ignoring"

Two separate causes

1. The flag form. Given --class NAME, Ghostty treats --class as a flag with no
   value and reports "class: value required", then parses NAME as another config
   field and reports "invalid field". That is what the window is showing.

2. The names. Ghostty validates class as a GTK app id, and those cannot contain
   hyphens. ryoport-ssh, ryovm-ssh and ryoku-passkey are all rejected, so
   even with the right flag form the window keeps com.mitchellh.ghostty.

Window rules

window_rules.lua matches on those class names:

hl.window_rule({ name = "float-ryoport-ssh", match = { class = "ryoport-ssh" }, float = true, size = fit(900, 560), center = true })

With Ghostty the class never lands, so these windows are not floated or centred.
The rule cannot match. The dialog also has to be dismissed each time.

Call sites

• ryoku/apps/ryovm/quickshell/Singletons/Remotes.qml:173 (ryoport-ssh, copy id)
• ryoku/apps/ryovm/quickshell/Singletons/Remotes.qml:180 (ryoport-ssh, run on host)
• ryoku/apps/ryovm/quickshell/Singletons/Vm.qml:781 (ryovm-ssh)
• ryoku/apps/ryovm/quickshell/SettingsPanel.qml:187 (ryovm)
• ryoku/hub/quickshell/pages/LockscreenPage.qml:326 (ryoku-passkey)

All five pass the class the same way.

Fixing it

The terminal is configurable, so the flag should be built for whichever one is
set instead of assuming kitty. Both parts above need handling: the flag form, and
names GTK will accept together with the matching window rules.

Ghostty and kitty are both installed here if a patch needs testing.
