Paleofetch for NixOS

Description

Fork of paleofetch-fedora (which itself is a fork of paleofetch that adds the fedora logo) adjusted to show the NixOS logo. The original paleofetch was itself a rewrite of neofetch in C.

Currently only supports Linux and Xorg.

So what the heck is it? It shows info like this:

But does it faster than neofetch, so you can safely put it at the end of you bashrc/zshrc

Why use paleofetch over neofetch?

One major reason is the performance improvement. For example: neofetch finishes running after about 222 milliseconds where as paleofetch can finish running in a blazing fast 3 milliseconds.

Note: this testing occured on only 1 computer, it's not a good representation on the performance benefit you may gain.

Compiling

Dependencies

Paleofetch requires libX11 and libpci. If you're running Xorg you should already have the former. On Arch Linux, you should have libpci already installed if you have pciutils installed. On other linux distrobutions, you may need to install libpci seperatley if its not already present.

On NixOS, to build, you'll need a separate nix-shell with pciutils and xorg.libX11, but I'm assuming your system already has make and gcc at the top-level.

Manual

nix-shell -p pciutils xorg.libX11
make

Configuration

In your configuration.nix, add the following to the top just after the { config, pkgs, ... } but before the next {:

{ config, pkgs, ... }:

let
    paleofetch = pkgs.stdenv.mkDerivation rec {
        name = "paleofetch";
        src = pkgs.fetchFromGitHub {
            owner = "blueOkiris";
            repo = "paleofetch-nixos";
            rev = "<latest github commit>";
            sha256 = "<result of 'nix-prefetch-url --unpack https://github.com/blueOkiris/paleofetch-nixos/archive/that-github-commit-from-above.tar.gz'>";
        };
        buildInputs = [ pkgs.gcc pkgs.gnumake pkgs.pciutils pkgs.xorg.libX11 ];
        buildPhase = ''
            mkdir -p $out
            cp -ra $src/* $out
            cd $out
            make
            rm -rf obj/
        '';
        installPhase = ''
            mkdir -p $out/bin
            cp $out/paleofetch $out/bin
        '';
    };
in {
    ...
}

Usage

After compiling, simply run the executable: ./paleofetch, or just paleofetch if installed on the system.

By default, paleofetch will cache certain information (in $XDG_CACHE_HOME/paleofetch) to speed up subsequent calls. To ignore the contents of the cache (and repopulate it), run paleofetch --recache

The cache file can safely be removed at any time, paleofetch will repopulate it if it is absent.
