wfetch

wfetch is an opinionated command-line fetch tool for displaying system information in a pretty way. It is written in Rust and is a wrapper around fastfetch.

Installation

Add wfetch to your inputs in your flake.nix:

{
  inputs.wfetch.url = "github:iynaix/wfetch";
}

A wfetch cachix is also available, providing prebuilt binaries. To use it, add the following to your configuration:

{
  nix.settings = {
    substituters = ["https://wfetch.cachix.org"];
    trusted-public-keys = ["wfetch.cachix.org-1:lFMD3l0uT/M4+WwqUXpmPAm2kvEH5xFGeIld1av0kus="];
  };
}

Warning

Overriding the wfetch input using a inputs.nixpkgs.follows invalidates the cache and will cause the package to be rebuilt.

Then, include it in your environment.systemPackages or home.packages by referencing the input:

inputs.wfetch.packages.${pkgs.system}.default

Alternatively, it can also be run directly:

nix run github:iynaix/wfetch
