The Complete Computer

This document collects some support that is shared between Arroyo NixOS Generator and Arroyo Home Manager . It sets up the nixpkgs overlay, the injection of a custom Nix packages in to the Arroyo systems' nixpkgs pkgs attrset, etc.

So Arroyo dumps the tangled Nix files in to ~/arroyo-nix/:

I have a handful of packages I want to export and include here. I have been trying to maintain a branch of nixpkgs containing my changes but it's been awfully difficult to keep it up to date and i haven't had the mental wherewithal to clean the changes up enough to merge in to nixpkgs.

nix source: :tangle ~/arroyo-nix/default.nix :noweb yes
{ pkgs ? import <nixpkgs> {} }:

with pkgs;
rec {
  # The `lib`, `modules`, and `overlay` names are special
  lib = import ./lib { inherit pkgs; }; # functions
  # modules = import ./modules; # NixOS modules
  # overlays = import ./overlays; # nixpkgs overlays
  overlays = [
    (import ./overlay.nix)
  ];

  <<gen-pkg-overlays(rix-pkgs)>>

  drawingbot-premium = (drawingbot-free.override {
    name = "drawingbotv3-premium";
  }).overrideAttrs (old: old // {
    src = /home/rrix/sync/DrawingBotV3-Premium-1.6.9-beta-linux.deb;
    meta.license = pkgs.lib.licenses.unfree;
  });

  # plasma5Packages = let
  #   p5pcc = pkgs.plasma5Packages.overrideScope (pFinal: pPrev: rec {

nixpkgs configuration needs to be passed in when the module is instantiated, doing it in your config isn't supported. This import is used as <arroyo/pkgs/nixpkgs.nix> by e.g. the Morph Command Wrapper , flakes will have to do this on their own still:

nix source: :tangle ~/arroyo-nix/pkgs/nixpkgs.nix
{ ... }:

import <nixpkgs> {
	allowUnfree = true;
  permittedInsecurePackages = [
    "olm-3.2.16"
  ];
}

These turn the tables above in to code embedded above that:

 gen-pkg-overlaysemacs-lisp source: :var tbl=wrapWine-pkgs
(mapconcat (lambda (row)
             (format "%s = callPackage %s {};\n" (second row) (third row)))
           tbl)

 gen-python-overlaysemacs-lisp source: :var tbl=python-pkgs
(mapconcat (lambda (row)
             (format "%s = toPython%s (callPackage %s {});\n" (second row) (fourth row) (third row)))
           tbl)

Arroyo exposes some library helpers which i would like to not just bare-import:

nix source: :tangle ~/arroyo-nix/lib/default.nix
{ pkgs }:

with pkgs.lib; {
  pkgVersions = pkgs.callPackage ../versions.nix {};
  mkKwriteConfig5 = pkgs.callPackage ./kde-configs.nix {};
  mkNixGLWrapper = pkgs.callPackage ./nixgl.nix {};
  mkActivationLocalLink = pkgs.callPackage ./mk_activation_local_link.nix {};
  publicKeys = import ./public-keys.nix;
}

Since arroyo is in my =NIX_PATH= , i can just import it. home-manager is configured to use the system nixpkgs.

nix source: :tangle ~/arroyo-nix/nixos/rixpkgs.nix
{ pkgs, ... }:

{
  nixpkgs.overlays = [
    (import <arroyo/overlay.nix>)
  ];
}

Arroyo-Nix could be used as an nixpkgs overlay, this exposes all the stuff in default.nix as a nixpkgs overlay.

nix source: :tangle ~/arroyo-nix/overlay.nix
self: super:
let
  isReserved = n: n == "lib" || n == "overlays" || n == "modules";
  nameValuePair = n: v: { name = n; value = v; };
  nurAttrs = import ./default.nix { pkgs = super; };

  outAttrs = builtins.listToAttrs
  (map (n: nameValuePair n nurAttrs.${n})
    (builtins.filter (n: !isReserved n)
      (builtins.attrNames nurAttrs))) // {
        lib = (super.lib or {}) // (import ./lib/default.nix { pkgs = super; });
      };
in outAttrs

and probably one for lib... uagh.
