Installing libfetch on NixOS using Flakes

libfetch is a GNU/Linux port of the FreeBSD userland utility similar to Wget. I created it because I really didn’t like how heavy Wget is, and I didn’t have the knowledge to write it from scratch so I decided to port it. It’s pretty lightweight compared to Wget. But let’s dive into installing it on NixOS if you’re interested in doing it.

Adding the input

First, add the libfetch input to your flake.nix.

{
  inputs = {
    libfetch = {
      url = "git+https://gitea.foss-daily.org/kayoubi13/libfetch";
      inputs.nixpkgs.follows = "nixpkgs"; # this line is optional, prevents downloading two versions of nixpkgs but disables cache
    };
  };
}

Alternatively you can use the GitHub mirror if you prefer being tracked by Microsoft and give up your User Rights.

{
  inputs = {
    libfetch = {
      url = "github:foss-daily/libfetch";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
}

For flakes instructions, we assume you are passing in libfetch through specialArgs or equivalent. Like this:

specialArgs = { inherit libfetch; }

Installing the Package

Add the package to your system packages or equivalent:

{ libfetch, pkgs, ... }:
{
  environment.systemPackages = [
    libfetch.packages.${pkgs.stdenv.hostPlatform.system}.default
  ];
}

After setting everything up

You can verify that everything is working by running:

fetch -o /dev/null https://proof.ovh.net/files/1Gb.dat

If everything went right, you should be ready to go! Have fun downloading whatever you need to! :D
