<p>
This repository contains a literate NixOS configuration built using Emacs Org mode. The primary source of truth is this document itself, which embeds configuration blocks that are tangled into individual files. These generated files are evaluated as a NixOS flake, resulting in an immutable, reproducible system configuration.
</p>
<p>
This work is based on the foundational efforts of Sandeep Nambiar (<a href="https://github.com/gamedolphin">https://github.com/gamedolphin</a>).
All credit for the original structure, methodology, and guidance belongs to him. His work provided the architectural basis and practical direction upon which this repository is built. This project would not have been possible without his prior contributions, and much of the instructional approach preserved here originates from his documentation.
</p>
<p>
The purpose of this repository is to offer a structured, minimal starting point for deploying a functional NixOS system. It is intentionally not a complete desktop environment, nor is it a “batteries-included” distribution. Instead, it provides a clean and extensible foundation that can be adapted and expanded after installation.
</p>
<p>
Customization is designed to occur primarily through modular .conf files, allowing the system to evolve incrementally while maintaining clarity and separation of concerns. The goal is to enable users to build their own tailored NixOS setup on top of a coherent and reproducible base.
</p>
<p>
Before proceeding with installation, it is strongly recommended to read this documentation carefully. Understanding the structure and design philosophy will help ensure a smooth setup and provide the necessary context for extending the system effectively.

<li>a NIXOS system installed (can be bare-bones)</li>

<p>
To set up a connection from cli:
</p>
<div class="org-src-container">
<pre class="src src-bash"># Check if NetworkManager service is running
systemctl status NetworkManager
# If not running, start it temporarily
sudo systemctl start NetworkManager
# Enable Wi-Fi radio (in case it is disabled)
nmcli radio wifi on
# List available Wi-Fi networks
nmcli device wifi list
# Connect to a Wi-Fi network (replace SSID and PASSWORD)
nmcli device wifi connect "SSID_NAME" password "YOUR_PASSWORD"
# Verify that the connection is active
nmcli connection show --active
# Optional: show device status
nmcli device status

<div class="outline-text-2" id="text-3">
<p>
To generate the Nix files:
</p>
<div class="org-src-container">
<pre class="src src-bash">emacs README.org --batch -f org-babel-tangle
</pre>
</div>
<p>
Test the build while being able to reboot to previous version
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo nixos-rebuild test --flake .#machine1
</pre>
</div>
<p>
Build and switch to this version on the next reboot
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo nixos-rebuild switch --flake .#machine1
</pre>
</div>
<p>
Build and run in a virtual machine (qemu must be installed)
</p>
<div class="org-src-container">
<pre class="src src-bash">sudo nixos-rebuild build-vm --flake ~/nixos-henrov#machine1
# running the vm:
./result/bin/run-nixos-vm
</pre>
</div>
<p>
un this VM with result/
</p>
<div class="org-src-container">
<pre class="src src-bash">emacs README.org --batch -f org-babel-tangle
</pre>
</div>
<p>
Once the Nix files are generated, deploy using:
</p>
<div class="org-src-container">
<pre class="src src-bash">nixos-rebuild switch --flake .#&lt;machine&gt;
</pre>
</div>

This repository contains system modules, user modules, and configuration fragments. The following directories are treated as separate layers:
<code>./configuration</code> (NixOS modules), <code>./home</code> (Home Manager modules), and <code>./assets/conf</code> (configuration fragments referenced or deployed by the modules).

To keep navigation consistent, the same internal substructure is used in all three locations. Each layer keeps its role; only the internal grouping is standardized.

<code>YourNixCode(Input) -&gt; System Configuration</code>
</p>
<p>
I use <a href="https://nixos.wiki/wiki/Flakes">nix flakes</a> which means that the entry point for the nix evaluation is a file called <code>flake.nix</code> which has two parts (among other things)
</p>
<div class="org-src-container">
<pre class="src src-nix">{
inputs: # describes the function input, consisting mainly of package sources
outputs: # what the function outputs, a nixos configuration in our case
}
</pre>
</div>
<p>
Nix flakes is still behind an <code>experimental</code> flag, but it is de facto the standard by most of the community.
Flakes allow us to pin the input package versions using a <code>flake.lock</code> file.
This prevents unwanted and surprise updates when rebuilding without changing the configuration.

I have a bunch of constant strings that I would rather put in a file. Thats what <code>user.nix</code> is.
The values are imported at the beginning and are available to almost all the functions being called to configure the system.

</p>
<ol class="org-ol">
<li><a href="https://search.nixos.org/packages">nixpkgs</a> - the main nix repository of packages. Its huge and growing. Pinned to the unstable release channel.
Sometimes pinned to a specific commit because unstable broke something and the fix hasn't made it into the release yet.</li>
<li><a href="https://nix-community.github.io/home-manager/">home-manager</a> - a nix module that helps keep track of user specific dotfiles and configurations as part of my nix config.</li>
<li><a href="https://github.com/nix-community/emacs-overlay">emacs-overlay</a> - this has more configuration options and generally a newer emacs available provided by the community.</li>

<p>
Now that the inputs are ready, the outputs define what the system will actually look like. I also define the machines that this configuration specifies early on. Finally, I iterate over the <code>machines</code> list and pull files from <code>/.machines/${name}</code> subdirectory. This allows me to have configuration that has machine specific configuration limited to those files while also keeping a modular reusable base.
We also add a devshell that makes editing this repository easier in emacs.

Lets look at the individual modules

<ol class="org-ol">
<li><p>
Emacs
The first is the emacs overlay so that it uses the nix-community emacs overlay from the inputs instead of the nixpkgs one.
Overlays are a special nix way to override existing packages within a repository.

Then the machine specific configuration, in this case, just "traveldroid".

<div class="org-src-container">
<pre class="src src-nix" id="org2b21236">./machines/${machine}/configuration.nix
</pre>
</div></li>
<li><p>
And finally the home-manager module.
This can be initialized and managed on its own but I'd rather use the <code>nixos-rebuild</code> command to build everything instead of managing userland dotfiles separately.
</p>
<div class="org-src-container">
<pre class="src src-nix" id="org9e2d3d1">home-manager.nixosModules.home-manager

&lt;&lt;flake-home-config&gt;&gt;
}
</pre>

<ul class="org-ul">
<li><p>
Home-Manager will not overwrite existing configuration files and that is good in most cases, but when everything is declarative like it is here, I'd rather that home-manager create a <code>.backup</code> and replace the file.

Editing this file will be much nicer if we have the dev environment configured.
That is done in the devshells section. But to auto load this dev shell, we need a .envrc file.
This tells <a href="https://direnv.net/">direnv</a> to load the devshell in the flake.

I practically live inside emacs. The configuration for it is a mix between init.el and the nix configuration.
Nix allows me to install emacs packages as part of the configuration which is most of the following file.
I install the nix community provided emacs overlay that lets me have the latest emacs with pgtk ui (for wayland).
Comments describe the emacs package and what it does.
