hyprland: submaps cannot be configured with nix syntax

[0x57e11a]

hyprland does an odd thing in its usage of hyprlang with submap = ..., which switches into different submaps when binding keys (ideally this would've been implemented as different submap:xyz { ... } sections, but they Decided To Do It That Way for some reason)

# other keybinds

submap = something

bindm = , mouse:272, movewindow
bind = , escape, submap, reset

submap = reset

# other keybinds

because this specific section of keybinds needs to be surrounded by submap boundaries, it's not possible to do this with wayland.windowManagers.hyprland.settings

solution

the proposal is to add wayland.windowManagers.hyprland.submaps, like so:

wayland.windowManager.hyprland.submaps = {
    something = {
        bindm = [ ", mouse: 272, movewindow" ];
        bind = [ ", escape, submap, reset" ];
    };
};

workaround

wayland.windowManagers.hyprland.extraConfig exists, but having part of the config in a string and the rest in nix options is frustrating
