Using import nixpkgs { inherit system; } inside lib.genAttrs can be inefficient as it re-evaluates the nixpkgs import for each system. A more idiomatic and efficient approach in flakes is to use nixpkgs.legacyPackages.${system}.

      forAllSystems = f:
        lib.genAttrs supportedSystems (
          system: f nixpkgs.legacyPackages.${system}
        );

The mkGlideBundle function can be made more robust and maintainable by using some standard Nix helper functions.

  • Explicitly declare nativeBuildInputs like makeWrapper and coreutils for tools used in the script.
  • Generate the Info.plist file using pkgs.writeText outside the script to separate data from logic.
  • Use pkgs.makeWrapper to create the glide-launch script, which is the standard way to create wrapper scripts in Nix.

Here's a suggested refactoring that applies these improvements:

      mkGlideBundle = pkgs: unbundled:
        let
          infoPlist = pkgs.writeText "Info.plist" ''
            <?xml version="1.0" encoding="UTF-8"?>
            <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
