fletchling

A light and stylish fetcher written in Nim

Introduction

fletchling is a system information fetcher that seeks to be fast and light. While small, it's also customizable and gets the job done with style.

It uses what Nim has to offer to its advantage:

• Small executable size
• Dependency-free
• Quick performance

Note

fletchling is in alpha and in heavy development. I regularly use it on NixOS, but it's not guaranteed to work on other systems yet.

Why fletchling?

fletchling started as my first program in POSIX shell. The language and syntax weren't quite the right tools for the job as it grew in complexity, so I rewrote it to start learning Nim instead.

Hence, the portmanteau of "fetch" and "fledgling."

Installation

Nimble

TODO

Nix Flake

Add fletchling to your flake inputs and overlays.

Then you can add it to your packages with pkgs.fletchling.

Example:

{
  inputs = {
    fletchling.url = "github:mimvoid/fletchling";
  };

  outputs = { self, nixpkgs, ... } @ inputs:
    let
      system = "your-system";
      pkgs = import nixpkgs {
        inherit system;
        overlays = [ inputs.fletchling.overlay ];
      };
    in
    {
      nixosConfigurations."your-hostname" = nixpkgs.lib.nixosSystem {
        inherit system pkgs;
        modules = [
          (
            { pkgs }:
            {
             environment.systemPackages = with pkgs; [ fletchling ];
            }
          )
        ];
      };
    };
}

Special Thanks

I want to give my thanks to nitch for being my first introduction to Nim and a major inspiration for this project.
