This is a nix flake for GNOME Workbench. Credits to both the developers of Workbench and those involved at NixOS/nixpkgs#208866

Warning

This flake has not been tested. See note at bottom for more information

Usage

This nix flake exposes two packages. The first is, well, workbench and can be accessed with either packages.x86_64-linux.default or packages.x86_64-linux.workbench. The second is gtk-css-lsp, which is a dependency of workbench that is not available in nixpkgs. The code for that derivation belongs to a contributor to the Nix User Repository.

To run either package, you can run

nix run github:aytizren/nix-workbench#<package>

where <package> is one of gtk-css-lsp,workbench, or default(which is an alias for workbench).

Either one can be integrated into your home-manager or NixOS setup using an approach similar to the following:

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";
    workbench = {
      url = "github:aytizren/nix-workbench";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
  

  outputs = {nixpkgs, workbench, ...}: {
    devShells.x86_64-linux.default = nixpkgs.legacyPackages.x86_64-linux.mkShell {
      packages = [
        # Two relevant lines:
        workbench.packages.x86_64-linux.workbench
        workbench.packages.x86_64-linux.gtk-css-lsp
      ];
    }
  };
}

Cache usage

This flake also has a cachix-hosted cache.

On NixOS, if you want to add it system-wide, add the following lines to your configuration:

nix.settings = {
  substituters = ["https://nix-workbench.cachix.org"];
  trusted-public-keys = ["nix-workbench.cachix.org-1:UlsphKxYbmI4lCXnJAuNDHzH9L92Rr7syeGQUq0Mm2o="];
};

If you want to use it in any way locally(user-specific nix.conf or even the CLI), you have one of two options, depending on your setup.

If your user is a member of `trusted-users`

In this case, you can use this with no further complication. If you want to save this cache, simply add it to your user-specific `nix.conf`.

Home manager example:

nix.settings = {
  extra-substituters = ["https://nix-workbench.cachix.org"];
  extra-trusted-public-keys = ["nix-workbench.cachix.org-1:UlsphKxYbmI4lCXnJAuNDHzH9L92Rr7syeGQUq0Mm2o="];
};

If you want to use it for one-time invocations, you can simply use

nix --accept-flake-config run github:aytizren/nix-workbench#<package> 

Side note: Blindly using --accept-flake-config is not good practice. See NixOS/nix#9649

If your user is not a member of `trusted-users`

In this case, you will have to add the cache to the system-wide, global `nix.conf`. [Relevant excerpt from the Nix manual](https://nix.dev/manual/nix/2.28/command-ref/conf-file#conf-trusted-substituters): > `trusted-substituters` > > A list of Nix store URLs, separated by whitespace. These are not used by default, but users of the Nix daemon can enable them by specifying substituters. > > Unprivileged users (those set in only allowed-users but not trusted-users) can pass as substituters only those URLs listed in trusted-substituters.

You will have to do the following in your nix.conf:

nix.settings = {
  trusted-substituters = ["https://nix-workbench.cachix.org"];
  trusted-public-keys = ["nix-workbench.cachix.org-1:UlsphKxYbmI4lCXnJAuNDHzH9L92Rr7syeGQUq0Mm2o="];
};

This has not been rigorously tested

This flake has not be tested with workflows involving any programming language, nor even CSS or Blueprint for that matter.
