How to Install wantguns-bin on NixOS Latest

This tutorial will guide you through the process of installing the wantguns-bin package on NixOS Latest. wantguns-bin is a binary package that can be found on GitHub. We will be using the Nix package manager to install the package.

Prerequisites

Before we get started, ensure that your system has the following prerequisites:

Nix package manager - this comes pre-installed on NixOS.
A stable internet connection.

Installation Steps

Open a terminal and navigate to the desired directory where you want to install the package.
Clone or download the wantguns-bin package from GitHub using the following command:
```
git clone https://github.com/wantguns/bin.git
```
Once the download is complete, navigate into the bin directory using the following command:
```
cd bin/
```
Now, we will add the wantguns-bin package to the Nix package manager by creating a Nix file. Create a file named default.nix by running the following command:
```
touch default.nix
```

Open the default.nix file in a text editor and insert the following code:

{ pkgs ? import <nixpkgs> {} }:

pkgs.stdenv.mkDerivation rec {
    name = "wantguns-bin";

    src = ./.;

    installPhase = ''
        mkdir -p $out/bin
        cp ${src}/wantguns $out/bin/wantguns
    '';
}

This code will create a new derivation for wantguns-bin by copying the wantguns binary file into the bin directory.

Save and close the default.nix file.
Next, we will build and install the wantguns-bin package. Run the following command:
```
nix-env -f ./default.nix -iA wantguns-bin
```
The wantguns-bin package should now be installed on your system. To check, run the following command:
```
wantguns -h
```
If the installation was successful, you should see the usage information for the wantguns command.
