Home Manager is a basic system for managing a user environment using the Nix package manager together with the Nix libraries found in nixpkgs.

• readme • Wiki • Manual •

Home Manager works anywhere that Nix does and populates a ~/.nix-profile which is added to various environment PATHs to expose a bunch of Nix packaged programs to the rest of my system. I plan to slowly fork all of my Ansible automation in to this system and when the bulk of it is moved I can evaluate building fully idempotent systems with NixOS and NixOps. oh what fun! See below a cool method to generate some foot-gun shaped code!

Emacs scaffolding via CCE

This document relies on some [[id:e050ed03-044f-4a48-912d-72579bef9a26][org-roam keyword caching]] this is handled by Arroyo Emacs now.

(with-eval-after-load 'org-roam-keywords
  (dolist (kw '("CCE_HOME_MODULE" "CCE_HOME_PACKAGES" "CCE_HOME_DERIVATIONS" "CCE_HOME_EPKGS"))
    (add-to-list 'org-roam-cached-keywords kw nil #'equal)))
(provide 'cce/home-manager)

CCE Modules Which This Loads

Here are files which will be included by home-manager:

(->>
 (org-roam-db-query [:select [file title]
                     :from keywords
                     :join titles :using [[file]]
                     :where (= keyword "CCE_HOME_MODULE")
                     :group-by file])
 (seq-map (lambda (item) (format "- [[file:%s][%s]]\n" (file-relative-name (first item) cce-directory) (second item))))
 (apply #'concat))

Quickly Install it

With a working Nix installation run this to install home-manager:

nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
nix-channel --update
nix-shell '<home-manager>' -A install

Additionally, Cachix can be used to skip compiling the Emacs GCC branch on NixOS systems. Here it's not so helpful

nix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use nix-community

Generating `home-manager.nix` dynamically with noweb Literate Programming

This uses my org-roam keyword caching patch and the Shared CCE Helpers to dynamically generate a home.nix. some neat and tidy roam:ELisp is nice to see. Every page with home manager code in it will carry a CCE_HOME_MODULE keyword with the location of the .nix file for that CCE module which will be inserted in to the home.nix template.

It's complicated because I need to define home.packages only in one place and I can't figure out a better way to compose this file. This relies on some implied code standards to work: home.packages will be populated with things hidden under lib.mypkgs.FOO, a list of packages concatenated with all the other lib.mypkgs but reliant on very particular shape and naming. Inherent limitation to the craft, I guess.

I also should define program modules for a lot of these over the long term so that they're more simple to harness and my configurations can become more stable. This references a lot of code in the Shared CCE Helpers, consider reading that if you're interested in understanding this.

for now, this is going to be kind of awkward. I have a Fedora Linux that is reliant on this home.nix, but i want nodes managed with NixOps to have access to this during a bootstrap.

{ config, pkgs, lib, ... }:

{
  imports = [
    <<generate_imports()>>
  ];  

  programs.home-manager.enable = true;
  home.stateVersion = "21.05";

  home.file.".config/nixpkgs/home.nix".source = ./home-manager.nix; # this file

  manual.html.enable = true;
  manual.json.enable = true;
  news.display = "silent";

  home.username = "rrix";
  home.homeDirectory = "/home/rrix";

  # set to UTF-8 or python shit breaks
  home.language.base = "en_US.UTF-8";
  home.language.time = "en_GB.UTF-8";

  # for KDE
  # https://userbase.kde.org/Session_Environment_Variables
  home.file.".config/plasma-workspace/env/profile.sh".text = ''
    source $HOME/.profile
  '';
}
