Currently, waybar-hyprland package adds `prev.hyprland` to `$PATH`. This is nixpkgs' default hyprland, not hyprland injected by this overlay. I'd expect we want waybar-hyprland to depend on what's in `pkgs.hyprland` after this (and possibly user's other overlays) are applied – which is `final.hyprland`.
Fixes no useful feedback about failing subcommand.
Fixes function hooks breaking when running under a path containing
spaces.
Replaced old usages with this function where possible.
Complex shell usages now use `execAndGetShell` which is equal to the
old function.
* nix: flake: fix improperly using prev.callPackage
* flake: cleanup with let blocks
* flake: make overlays use recursive packages
flake: separate overlays into multiple, combine into default
* nix: overlays: extract to own file
* flake: devShells: remove stdenv override
* overlays: hl-pkgs: xdph: remove needless overlay
Since the packages are now built with the overlays combined from inputs
and self, overriding specific dependencies (anywhere) is no longer
necessary.
* nix: overlays: extras: include xdph and share-picker
* nix: overlays: hl-pkgs: remove stdenv override
