# Nixpkgs overlay with GNUnet-related packages
This repository contains experimental packages related to [GNUnet](https://gnunet.org) for the [Nix package manager](https://nixos.org/nix). There exists a GNUnet package in the official nixpkgs repository but as GNUnet is still under heavy development, it is recommended to use a fairly recent version from the master branch of GNUnet's git repository.

Currently the overlay provides these packages:

- GNUnet itself
- libgnurl

## Installation
We can install the overlay into the user environment like this:

```shell
$ ln -s ~/.config/nixpkgs/overlays/gnunet-overlay.nix gnunet-overlay
```
Now we can install the packages using

```shell
$ nix-env -f '<nixpkgs>' -iA gnunet
```

To use the packages from the overlay system-wide (on NixOS) we can add this to our ``/etc/nixos/configuration.nix``:

```
{ config, pkgs, ... }:

{
  ...
  nixpkgs.overlays = [
    (import (fetchGit https://ulrich.earth/code/nixpkgs-gnunet))
  ];

  environment.systemPackages = with pkgs; [
    ...
    gnunet
  ];
  ...
}
```
