Footnotes

tf2-nix provides a framework for configuring Team Fortress 2 (TF2), a game that not only allows for, but sometimes demands, a surprising amount of hacking to optimise your experience. User customisations includes anything from essential performance tweaks, to aesthetic changes such as UI overhauls, hit-sounds, and animations, to basic scripting.

For the practical purposes including easy deployment and version-tracking, as well as "the spiritual purity of configuring computers correctly,"¹ tf2-nix was created. This project's goal is to provide complete configuration, package-management, and, when possible, packages themselves, for TF2.

Disclaimers

This is an alpha status project

At the moment, this project should mostly be considered a proof of concept. It is usable, I am using it, but it is pretty bare-bones. I hope to gradually expand this project anon. More packages, modules, all the Nix goodness we're accustomed to.

Further, I'm not the most experienced Nix user. Expect bad code and unidiomatic interfaces. I encourage you to point out said bad code if you spot it. }:)

TF2 is a radioactive zigzagging target

In my experience, TF2 and Valve software in general react very dramatically²³ when prodded with even slightly unorthodox setups. Brace yourself before updating TF2, and never be afraid to open an issue here.

FAQ (Frequently-anticipated questions)

How make Impermanence work?

See nix-community/impermanence#165:

If ~/.local/share/Steam is persisted using a symlink, Steam works, but home.file breaks.
If ~/.local/share/Steam is persisted using a bind-mount via Impermanence's Home-manager module, Steam breaks, but home.file works.
If ~/.local/share/Steam is persisted using a bind-mount via Impermanence's NixOS module, Steam works, and home.file works!

Usage

tf2-nix is dead simple. No modules of any variety are provided (at this point in time). A TF2 'config' is packaged into a derivation resembling TF2's tf directory, and several config derivations are merged to create your final configuration. It is then left to you, the user, to install it as you wish. Most often, home.file.${path-to-tf-dir} = {source = your-config; recursive = true;} will suffice.

TL;DR

As a flake

Bring in the input, and build your TF2 config as a package:

  {
    inputs = {
      tf2-nix.url = "path:///home/crumb/src/tf2-nix";
    };

    outputs = { self, ... }@inputs:
      let
        system = "x86_64-linux";
        pkgs = import inputs.nixpkgs { inherit system; };
        tf2pkgs = inputs.tf2-nix.packages.${system};
        my-tf2-config = tf2pkgs.mergeTf2Configs (with tf2pkgs; [
          # Your chosen packages.
          mastercomfig.presets.medium-low
          mastercomfig.addons.flat-mouse
          mastercomfig.addons.no-tutorial
          mastercomfig.addons.null-canceling-movement
          improved-crosshairs
          loadouts-script
          # If you have a directory with the following structure, you can import
          # it here to merge it into your config.
          #     my-existing-config
          #     ├── cfg
          #     │   └── ...
          #     ├── custom
          #     │   └── ...
          #     └── maps
          #         └── ...
          ./my-existing-config
        ]);
      in {
        # ...
      };
  }

You can then install your configuration into TF2's tf directory:

  ### home.nix
  let
    # Confirm that this is actually where your tf dir lives!
    tf-dir = ".local/share/Steam/steamapps/common/Team Fortress 2/tf";
  in {
    home.file.${tf-dir} = {
      source = my-tf2-config;
      recursive = true;
    };
  }

Rebuild your system, and rejoice!

HUDs

A package set of HUDs is generated primarily using data from hud-db, with a handful of manual additions and overrides. These HUDs are provided
