erosanix

This repository includes misc. Nix packages, NixOS modules, and Nix functions.

Setup as a Nix Flake

Setting up this repo as a Nix flake is no different than setting up any other flake:

flake.nix

{
  inputs.erosanix.url = "github:emmanuelrosa/erosanix";
  ...

  ouputs = { self, nixpkgs, erosanix, ...}: {
    nixosConfigurations.blah = nixpkgs.lib.nixosSystem {
      ...
      modules = [ erosanix.nixosModules.someModule ./configuration.nix ];
      ... 
    };
  };
};

configuration.nix

{ self, config, pkgs, lib, erosanix, ...}:
{
  environment.systemPackages = with pkgs; [
    erosanix.packages.x86_64-linux.somePackage
  ];
}

What's included?

Library functions

  • generic-bin-wrapper - A reusable function that is used to wrap the executables of an existing package, while making the wrapping transparent so that programs can still be launched from the "application menu." For an example, see the source for nvidia-offload-wrapper in lib/nvidia-offload-wrapper.nix. Wrappers created with generic-bin-wrapper are composable; Wrappers can wrap wrappers; To do this in a more readable fashion, see compose below.
  • makeDesktopIcon - The counter-part to makeDesktop from Nixpkgs; Used to scale the provided icon and install it in $out/usr/share
  • nvidia-offload-wrapper - Wraps the given package so that it renders on an NVIDIA GPU using NVIDIA's offload rendering. Ex. (nvidia-offload-wrapper pkgs.superTuxKart).
  • mkmupen64plus - Creates a launcher script to run a N64 game using mupen64plus. Also creates a corresponding menu item. Compose mupen64plus and nvidia-offload-wrapper using compose and you get a Nix package which launches a N64 game on your NVIDIA dGPU using offload rendering.
  • compose - Returns a function which when applied to an argument, applies the functions in the list, in the order provided. Ex 1. myFunc = compose [ mkmupen64plus nvidia-offload-wrapper ];. Ex 2. (compose [ mkmupen64plus nvidia-offload-wrapper ]) {...}
  • composeAndApply - Composes a list of functions (see compose above) and then applies them to the argument. Ex. composeAndApply [ mkmupen64plus nvidia-offload-wrapper ] {...}
  • mkSierraChartStudyFromSrc - A simple derivation function to cross-compile studies (indicators) for the Sierra Chart trading platform.
  • mkSierraChartStudyFromDLL - A simple derivation function install studies DLL's (indicators) for the Sierra Chart trading platform.
  • torsocks - Uses torsocks to allow you to use most applications in a safe way with Tor. Beware that torsocks it has its limits.
  • nanogl - Used to run OpenGL applications on Linux distributions other than NixOS, using Mesa drivers; NVIDIA drivers are not included. Based on nixGL.

Packages

This repo has quite a variety of packages.

Wine-compatible Windows applications

WARNING: The following Wine-compatible applications utilize my Nix derivation function mkWindowsApp, which creates something similar to the Nix store at $HOME/.cache/mkWindowsApp. Like the Nix store, this storage location will consume a lot of disk space over time unless you run the garbage collector periodically.
