Welcome to my personal NixOS configuration. This repository has been made mostly for testing out what NixOS can do and see how I can leverage on the paradigm of immutable systems in order to build the perfect configuration (at least for my own needs).

At the moment of writing this file, it does contain the configuration for two different systems:

• elendil: my personal laptop (Microsoft Surface Laptop 3 running NixOS)
• coravandil: the WSL on Windows 11 that I use at work, which uses Ubuntu 23.04 as the base system.

I plan to add a third one (a Lenovo Yoga currently running Fedora) in the near future.

The whole configuration uses the not-so-experimental feature of Nix Flakes along with a bunch of dependencies and tries to be as generic as possible in regarding of the system itself.

Elendil's Configuration

You will find the configuration for elendil in the system/elendil folder, it is composed of the classic configuration.nix file, containing the system itself and hardware-configuration.nix, which contains the custom linux kernel configuration.

Coravandil's Configuration

Since this is not a physical machine, there's nothing under the system folder for Coravandil, everything is in the configuration of the user, made using the excellent home-manager module.

Users

Two users are currently configured: massi@elendil and massi@coravandil. Since the two users share most of the things, I created reusable home-manager modules to easily configure them.

Home Manager Modules

I have created multiple modules for the users.

Base

As the name suggets, this is the base module, containing the initial things that have to be configured. Here I am using homeage in order to safely encrypt and decrypt the secrets for my users (for example the SSH key).

Fish

This is the module for the fish shell, which also installs a bunch of tools, configures some of the aliases and abbrs that I use on all the systems.

Fonts

This is the first module I wrote: it just installs a bunch of fonts and configures the fontconfig.

Helix

This is the module for the helix editor.

IM

A module that simply installs whatsapp, telegram and discord. In the future I will most probably add some serious email client, since the GNOME's integrated one isn't that useful.

Coding

Adds a lot of useful stuff for developers, like language servers, linters, formatters and such. This stuff is mostly then re-used by the NeoVim module to provide Intellisense, automatic formatting, integration with LSPs, etc. For now, the following languages are supported:

• C#
• Haskell
• Java
• Javascript (and Typescript)
• Json/Yaml via VSCode's LSP
• Lua
• Nix
• Purescript
• Racket
• Rust
• Terraform

On top of that, some other useful LSPs are installed:

• Dockerfile Language Server
• Helm Language Server
• Codeium AI Language Server
• Marksman for Markdown editing

NeoVim

This is the most complex and unstable module I wrote, the idea was to port my whole nvim configuration (which was quite old since I switched to VSCode) to the Nix ecosystem, make it immutable and such. It is kinda working right now, there are still a couple of bugs that I have to fix but it can be used for Java development without any issues.
