EUVlok Pkgs

This is a repo with pkgs meant for EUVlok, although it can be used by other repos as well too

Usage

Binary cache

This flake advertises the public eupkgs Cachix cache through nixConfig:

extra-substituters = [ "https://eupkgs.cachix.org" ];
extra-trusted-public-keys = [
  "eupkgs.cachix.org-1:V9Y0HdASNNSU9U6EkXhR1j85bZGRtNgW7wSyTiQrwGU="
];

Accept the flake configuration when Nix prompts to download prebuilt packages from Cachix instead of building them locally. For non-interactive use, pass --accept-flake-config. Multi-user Nix installations may require a trusted administrator to add the same substituter and public key system-wide.

GitHub Actions pulls from this cache for all checks. Builds on master and manually dispatched builds also push successful results using the repository's CACHIX_AUTH_TOKEN; pull requests remain read-only.

Add as a flake input

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    euvlok-pkgs.url = "github:euvlok/pkgs";
  };
}

Use packages in your configuration

Using overlays.default (recommended)

Composes into your own nixpkgs, so the resulting package set inherits your config (e.g. allowUnfree) and overlays

{
  # ...

  outputs = { self, nixpkgs, euvlok-pkgs, ... }: {
    nixosConfigurations.myHost = nixpkgs.lib.nixosSystem {
      modules = [
        ({ pkgs, ... }: {
          nixpkgs.config.allowUnfree = true;
          nixpkgs.overlays = [ euvlok-pkgs.overlays.default ];

          environment.systemPackages = with pkgs; [ claude-code yt-dlp ];
        })
      ];
    };
  };
}

Using legacyPackages

Note: legacyPackages is built from the nixpkgs this flake imports with no config applied, so unfree packages will be refused. Prefer overlays.default unless you explicitly want this flake's pinned nixpkgs.

{
  # ...

  outputs = { self, nixpkgs, euvlok-pkgs, ... }: {
    nixosConfigurations.myHost = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        {
          environment.systemPackages = with euvlok-pkgs.legacyPackages.x86_64-linux; [
            helium-browser
            yt-dlp
          ];
        }
      ];
    };
  };
}

Using in home-manager

{
  # ...

  outputs = { self, nixpkgs, euvlok-pkgs, home-manager, ... }: {
    homeConfigurations.myUser = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
      modules = [
        {
          home.packages = with euvlok-pkgs.legacyPackages.x86_64-linux; [
            helium-browser
            yt-dlp
          ];
        }
      ];
    };
  };
}

Cherry-picking a subset

If you only want a few packages in your top-level pkgs, wrap overlays.default and inherit what you need:

nixpkgs.overlays = [
  (final: prev: {
    inherit (prev.extend euvlok-pkgs.overlays.default) yt-dlp;
  })
];
