Introduction
This is my personal configuration for GNU/Linux systems. It enables a consistent experience and computing environment across all of my machines. This project is written with GNU/Emacs, leveraging its capabilities for Literate Programming, a technique where programs are written in a natural language, such as English, interspersed with snippets of code to describe a software project.
This file is controlled by /etc/dotfiles/README.org
Getting Started
-
Clone the project
git clone git@git.chrishayward.xyz:chris/dotfiles /mnt/etc/dotfiles -
Load the default shell
nix develop /mnt/etc/dotfiles -
Install the system
sudo nixos-install --impure --flake /mnt/etc/dotfiles#nixos -
Reboot, login and start a graphical system
startx
Making Changes
The nixos-rebuild command updates the system so that it corresponds to the configuration specified in the module. It builds the new system in /nix/store/, runs the activation scripts, and restarts and system services (if needed). The command has one required argument, which specifies the desired operation:
| Command | Description |
|---|---|
| boot | Build the new configuration and make it the boot default, without activation |
| test | Build and activate the new configuration, without adding it to the boot menu |
| switch | Build and activate the new configuration, making it the new boot default |
| build | Build the new configuration, without activation, nor adding it to the boot menu |
| build-vm | Build a script that starts a virtual machine with the desired configuration |
After making changes to the configuration the switch command will build and activate a new configuration.
# Build and activate a new configuration. sudo nixos-rebuild switch --flake $FLAKE#$HOSTNAME
Instead of building a new configuration, it's possible to rollback to a previous generation using the nixos-rebuild command, by supplying the --rollback argument.
# Rollback to the previous generation. sudo nixos-rebuild switch --rollback
Docker Container
It's possible to use parts of this configuration using a Docker container. By default, sandboxing is turned off inside of the container, even though it's enabled in new installations. This can lead to differences between derivations built inside containers, versus those built without any containerization. This is especially true if a derivation relies on sandboxing to block sideloading of dependencies.
Install from the command line: docker pull ghcr.io/chayward1/dotfiles:main
# <<file-warning>> # Derive from the official image. FROM nixos/nix # Setup the default environment. WORKDIR /etc/dotfiles COPY . . # Load the default system shell. RUN nix-shell /etc/dotfiles/shell.nix
Operating System
NixOS is a purely functional Linux distribution built on top of the Nix Package Manager. It uses a declarative configuration language to define entire computer systems, and allows reliable system upgrades and rollbacks. NixOS also has tool dedicated to DevOps and deployment tasks, and makes it trivial to share development environments.

};
outputs = inputs @ { self, nixpkgs, nixpkgs-unstable, ... }: {
<<host-configurations>>
} //
<<development-shells>>
}
Nixpkgs
Nixpkgs is a collection of over 60,000 software packages that can be installed with the Nix Package Manager. Two main branches are offered:
-
The current stable release
-
The Unstable branch following the latest development
nixpkgs.url = "nixpkgs/nixos-unstable"; nixpkgs-unstable.url = "nixpkgs/master";
Flake Utils
Flake Utils is a collection of pure Nix functions that don't depend on Nixpkgs, and that are useful in the context of writing other Nix Flakes.
flake-utils.url = "github:numtide/flake-utils";
Home Manager
Home Manager provides a basic system for managing user environments using the Nix Package Manager together with the Nix libraries found in Nixpkgs. It allows declarative configuration of user specific (non-global) packages and files.
home-manager.url = "github:nix-community/home-manager"; home-manager.inputs.nixpkgs.follows = "nixpkgs";
Emacs Overlay
Adding the Emacs Overlay extends the GNU/Emacs package set to contain the latest versions, and daily generations from popular package sources, including the needed dependencies to run Emacs as a Window Manager.
emacs-overlay.url = "github:nix-community/emacs-overlay";
NixOS Hardware
NixOS Hardware is a collection of NixOS modules covering specific hardware quirks. Unlike the channel, this will update the git repository on a rebuild. However, it's easy to pin particular revisions for more stability.
nixos-hardware.url = "github:nixos/nixos-hardware";
Development Shells
The command nix develop will run a bash shell that provides the build environment of a derivation. It's an experimental replacement for the nix-shell command that is compliant with Nix Flakes. It provides an interactive build environment nearly identical to what Nix would use to build installable. Inside this shell, environment variables and shell functions are set up so that you can interactively and incrementally build your package(s).

python = import ./shells/python.nix { inherit pkgs; };
rust = import ./shells/rust.nix { inherit pkgs; };
};
}
);
Nix
This shell adds a version of the nix command that is pre-configured to support Flakes. Flakes are the unit for packaging Nix code in a reproducible and discoverable way. They can have dependencies on other flakes, making it possible to have multi-repository Nix projects. A flake is a filesystem tree that contains a file named flake.nix. It specifies some metadata about the flake such as dependencies (inputs), as well as the values such as packages or modules (outputs).

Go
package main
import "fmt"
func main() {
fmt.Println("Hello, world!")
}
Go is an open-source programming language that makes it easy to build simple, reliable, and efficient software. It's statically typed and compiled programming language. It's syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency.

shellHook = ''
FLUTTER_SDK_DIR=${flutter}/bin/cache/dart-sdk/
'';
}
Rust
fn main() {
println!("Hello, world!");
}
Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. It is syntactically similar to C++, but can garantee memory safety by using a borrow checker to validate references. Rust achieves memory safety without garbage collection, and reference counting is optional.
Import this shell with nix develop $DOTFILES#rust
# <<file-warning>>
{ pkgs ? import <nixpkgs> { } }:
with pkgs;
mkShell {
buildInputs = [

Node
var http = require('http');
http.createServer((req, res) => {
res.WriteHead(200, { 'Content-Type': 'text/html' });
res.end('Hello, world!');
});
NodeJS is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine, and executes JavaScript code outside of a web browser. NodeJS lets developers user JavaScript to write command line tools, and for server-side scripting to produce dynamic web page content.

C/C++
#include <iostream>
int main() {
std::cout << "Hello, world!\n";
return 0;
}
C is a general-purpose, procedural computer programming language support structured programming, lexical variable scope, and recursion. It has a static type system, and by design provides constructs that map efficiently to typical machine instructions. C++ is a general-purpose programming language created as an extension of the C programming language.

Python
print("Hello, world!")
Python is an interpreted high-level, general-purpose programming language. Its design philosophy emphasizes code readability, with its notable use of significant indentation. Its language constructs, as well as its object-oriented approach aim to help programmers write clear, logical, code for small and large projects.
Import this shell with nix develop $DOTFILES#python

Host Configurations
NixOS typically stores the current machine configuration in /etc/nixos/configuration.nix. In this project, this file is stored in /etc/dotfiles/hosts/$HOSTNAME/..., and imported, along with the generated hardware configurations. This ensures that multiple host machines can share the same modules, and generating new host definitions is trivial.
nixosConfigurations = {
<<host-default>>
};
Shared
NixOS makes it easier to share common configurations amongst all of the hosts, such as with pre-configured wireless networking:
networking.wireless.networks = {
MyWiFi_5C1870 = {
priority = 2;
pskRaw = "409b3c85fef1c5737f284d2f82f20dc6023e41804e862d4fa26265ef8193b326";
};
SM-G975W3034 = {
priority = 1;
pskRaw = "74835d96a98ca2c56ffe4eaf92223f8a555168b59ec2bb22b1e46b2a333adc80";
};
};
It's helpful to add the machine hostnames to the networking configuration, so I can refer to another host across the network by name. Some devices that can have more than one IP (WIFI / Ethernet) will have the wireless hostname suffixed:
networking.hosts = {
# "192.168.3.105" = [ "gamingpc" ];
# "192.168.3.163" = [ "acernitro" ];
# "192.168.3.182" = [ "raspberry" ];
# "192.168.3.183" = [ "homecloud" ];
};
Setting up new machines, especially headless ones like the Raspberry Pi Zero, can be difficult with NixOS. I find it easier to setup automatic network configuration, and wait for the machine to appear on the network. This is complimented with a pre-authorized SSH key, making it simple to connect and complete the installation headlessly.
users.users.chris.openssh.authorizedKeys.keys = [ "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIO4wka/LfG3pto15DIm9LIRbb6rWr7/ipCRiCdAKSlY4 chris@chrishayward.xyz" ];
Default
The default host, built using QEMU, a free and open-source emulator that can perform hardware virtualization. It features a lightweight system optimized for development, running GNU/Emacs + EXWM as the graphical environment.
nixos = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
specialArgs = { inherit inputs; };
modules = [

Configuration
This is a basic default configuration that specified the indended default configuration of the system. Because NixOS has a declarative configuration model, you can create or edit a description of the desired configuration, and update it from one file.
# <<file-warning>>
{ config, pkgs, inputs, ... }:

isNormalUser = true;
extraGroups = [ "wheel" ];
};
system.stateVersion = "23.05";
}
Hardware
The file system for this host is a single 24GB QCOW file, a format for disk images used by QEMU. The file can be recreated easily by following the steps listed in the NixOS installation manual, specifically the section on disk formatting.

}
Module Definitions
Modules are files combined by NixOS to produce the full system configuration. Modules wre introduced to allow extending NixOS without modifying its source code. They also allow splitting up configuration.nix, making the system configuration easier to maintain and use.
X11
./modules/x11.nix
X11, or X is the generic name for the X Window System Display Server. All graphical GNU/Linux applications connect to an X-Window (or Wayland) to display graphical data on the monitor of a computer. Its a program that acts as the interface between graphical applications and the graphics subsystem of the computer.

Godot
./modules/godot.nix
Godot is a cross-platform, free and open-source game engine released under the MIT license. It provides a huge set of common tools, so you can focus on making your game without reinventing the wheel. It's completely free and open-source, no strings attached, no royalties. The game belongs to the creator down to each line of the engine code.

Flakes
./modules/flakes.nix
Nix Flakes are an upcoming feature of the Nix Package Manager. They allow you to specify your codes dependencies in a declarative way, simply by listing them inside of a flake.nix file. Each dependency is then pinned to a specific git-hash. Flakes replace the nix-channels command and things like builtins.fetchGit, keeping dependencies at the top of the tree, and channels always in sync. Currently, Flakes are not available unless explicitly enabled.
# <<file-warning>>

overlays = [ inputs.emacs-overlay.overlay ];
};
}
Cachix
./modules/cachix.nix
Cachix is a Command line client for Nix binary cache hosting. This allows downloading and usage of pre-compiled binaries for applications on nearly every available system architecture. This speeds up the time it takes to rebuild configurations.
# <<file-warning>>

Docker
./modules/docker.nix
Docker is a set of platform as a service tools that use OS level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels.
# <<file-warning>>

Firefox
./modules/firefox.nix
Firefox Browser, also known as Mozilla Firefox or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.
# <<file-warning>>

}
Home Manager
Home Manager includes a flake.nix file for compatibility with Nix Flakes, a feature utilized heavily in this project. When using flakes, switching to a new configuration is done only for the entire system, using the command nixos-rebuild switch --flake <path>, instead of nixos-rebuild, and home-manager seperately.
inputs.home-manager.nixosModules.home-manager {
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;

When Emacs is started, it normally tries to load a Lisp program from an ititialization file, or init file. This file, if it exists, specifies how to initialize and configure Emacs.

It's somtimes desirable to have customization that takes effect during Emacs startup earlier than the normal init file. Place these configurations in ~/.emacs.d/early-init.el. Most customizations should be put in the normal init file ~/.emacs.d/init.el.

Native Comp
pkgs.emacsNativeComp;
Native Comp, also known as GccEmacs, refers to the --with-native-compilation configuration option when building GNU/Emacs. It adds support for compiling Emacs Lisp to native code using libgccjit. All of the Emacs Lisp packages shipped with Emacs are native-compiled, providing a noticable performance iomprovement out-of-the-box.
;; Silence warnings from packages that don't support `native-comp'.
(setq comp-async-report-warnings-errors nil ;; Emacs 27.2 ...
native-comp-async-report-warnings-errors nil) ;; Emacs 28+ ...
Disable UI
Emacs has been around since the 1980s, and it's painfully obvious when you're greeted with the default user interface. Disable some unwanted features to clean it up, and bring the appearance to something closer to a modern editor.
;; Disable unwanted UI elements.
(tooltip-mode -1)
(menu-bar-mode -1)
(tool-bar-mode -1)
(scroll-bar-mode -1)
;; Fix the scrolling behaviour.
(setq scroll-conservatively 101)
;; Fix mouse-wheel scrolling behaviour.
(setq mouse-wheel-follow-mouse t
mouse-wheel-progressive-speed t
mouse-wheel-scroll-amount '(3 ((shift) . 3)))
;; Start in fullscreen/maximized.
(add-to-list 'default-frame-alist '(fullscreen . maximized))
Backup Files
Emacs makes a backup for a file only the first time the file is saved from a buffer. No matter how many times the file is subsequently written to, the backup remains unchanged. For files managed by a version control system, backup files are redundant since the previous versions are already stored.
;; Disable unwanted features.
(setq make-backup-files nil
create-lockfiles nil)
Shell Commands
Define some methods for interaction between GNU/Emacs, and the systems underyling shell:
-
Method to run an external process, launching any application on a new process without interference
-
Method to apply commands to the current call process, effecting the running instance
;; Define a method to run an external process.
(defun dotfiles/run (cmd)
"Run an external process."
(interactive (list (read-shell-command "λ ")))
(start-process-shell-command cmd nil cmd))
;; Define a method to run a background process.
(defun dotfiles/run-in-background (cmd)
(let ((command-parts (split-string cmd "[ ]+")))
(apply #'call-process `(,(car command-parts) nil 0 nil ,@(cdr command-parts)))))
Improved prompts
By default Emacs will ask you to enter 'Yes' or 'No' instead of 'Y' or 'N'. This is a relatively conservative design decision, based on the fact that certain prompts may be important enough to warrant typing three characters.
;; Use 'y' and 'n' instead of 'yes' and 'no'. (defalias 'yes-or-no-p 'y-or-n-p)
Nix Mode
pkgs.nixfmt pkgs.rnix-lsp
Nix Mode is an Emacs major mode for editing Nix expressions. This provides basic handling of .nix files. Syntax highlighting and indentation support using SMIE are provided. rnix-lsp is a work-in-progress language server for Nix with syntax checking and basic completion.
epkgs.nix-mode
Evil Mode
Evil Mode is an extensible VI layer for GNU/Emacs. It emulates the main features of Vim, transforming GNU/Emacs into a modal editor.
epkgs.evil epkgs.evil-collection epkgs.evil-surround epkgs.evil-nerd-commenter
The next time Emacs is started, it will come up in normal state, denoted by <N> in the modeline. This is where the main vi bindings are defined. Like Emacs in general, Evil Mode is extensible in Emacs Lisp.
;; Enable the Extensible VI Layer for Emacs.
(setq evil-want-integration t ;; Required for `evil-collection.'
evil-want-keybinding nil ;; Same as above.
evil-want-C-i-jump nil) ;; Disable jumping in terminal.

EXWM
epkgs.exwm
EXWM (Emacs X Window Manager) is a full-featured tiling X11 window manager for GNU/Emacs built on-top of XELB. It features:
-
Fully keyboard-driven operations
-
Hybrid layout modes (tiling & stacking)
-
Dynamic workspace support
-
ICCM/EWMH compliance
pkgs.nitrogen pkgs.autorandr
I wanted to leave (exwm-enable) out of my Emacs configuration (which does no harm anyways). This can be called when using the daemon to start EXWM.
xsession = {
enable = true;
windowManager.command = ''
${pkgs.nitrogen}/bin/nitrogen --restore
${myEmacs}/bin/emacs --daemon -f exwm-enable
${myEmacs}/bin/emacsclient -c
'';
};
EXWM cannot make an X window manager by itself, this is by design; You must tell X to do it. Override the ~/.xinitrc file to start the xsession.
home.file.".xinitrc" = {
text = ''
exec ./.xsession
'';
};

General
epkgs.general
General.el provides a more convenient method for binding keys in Emacs, providing a unified interface for key definitions. Its primary purpose is to build on existing functionality to make key definitions more clear and concise.
;; Use <SPC> as a leader key via `general.el'. (general-create-definer dotfiles/leader :keymaps '(normal insert visual emacs) :prefix "SPC" :global-prefix "C-SPC") ;; Setup general to work with `evil-mode'.

(dotfiles/leader "t" '(:ignore t :which-key "Toggle / Tweak"))
Which Key
Which Key is an Emacs minor mode that displays the key bindings following your currently entered incomplete command (prefix) in a popup or mini-buffer.
epkgs.which-key
;; Configure `which-key' to see keyboard bindings in the ;; mini-buffer and when using M-x. (setq which-key-idle-delay 0.0) (which-key-mode +1)
EWW

Dired
epkgs.dired-single
Dired Mode shows a directory listing inside of an Emacs buffer that can be used to perform various file operations on files and subdirectories. The operations you can perform are numerous, from creating subdirectories, byte-compiling files, searching, and editing files. Dired Extra provides extra functionality.
;; Include `dired-x' for the `jump' method. (require 'dired-x) ;; Configure `dired-single' to support `evil' keys. (evil-collection-define-key 'normal 'dired-mode-map "h" 'dired-single-up-directory "l" 'dired-single-buffer) ;; Configure keybindings for `dired'. (dotfiles/leader "d" '(dired-jump :which-key "Dired"))
Icons
epkgs.all-the-icons epkgs.all-the-icons-dired epkgs.all-the-icons-ivy-rich
All The Icons is a utility package to collect various Icon Fonts and prioritize them within GNU/Emacs.
;; Setup `all-the-icons-dired'. (add-hook 'dired-mode-hook 'all-the-icons-dired-mode) ;; Disable monochrome icons. (setq all-the-icons-dired-monochrome nil) ;; Display default font ligatures. (global-prettify-symbols-mode +1)
Emojis
epkgs.emojify
Emojify is an Emacs extension to display Emojis. It can display GitHub style Emojis like 😄 or plain ascii ones such as :). It tries to be as efficient as possible, while also providing flexibility.
;; Setup `emojify'. ;; TODO: Causes an exception. ;;(add-hook 'after-init-hook 'global-emojify-mode)
EShell
epkgs.eshell-prompt-extras
EShell is a shell-like command interpreter for GNU/Emacs implemented in Emacs Lisp. It invokes no external processes except for those requested by the user. It's intended to be an alternative for IELM, and a full REPL envionment for Emacs.
;; Configure `eshell'.
(setq eshell-highlight-prompt nil
eshell-prefer-lisp-functions nil)
;; Configure the lambda prompt.
(autoload 'epe-theme-lambda "eshell-prompt-extras")
(setq eshell-prompt-function 'epe-theme-lambda)
;; Configure keybindings for `eshell'.
(dotfiles/leader
"e" '(eshell :which-key "EShell"))
VTerm
Emacs Libvterm (VTerm) is a fully-fledged terminal emulator inside GNU/Emacs based on Libvterm, a blazing fast C library used in Neovim. As a result of using compiled code (instead of Emacs Lisp), VTerm is capable, fast, and it can seamlessly handle large outputs.
epkgs.vterm
;; Add keybindings for interacting with the shell(s). (dotfiles/leader "v" '(vterm :which-key "VTerm"))
Magit
Magit is an interface to the Git version control system, implemented as a GNU/Emacs package written in Emacs Lisp. It fills the glaring gap between the Git command line interface and various GUIs, letting you perform trivial as well as elaborate version control tasks within a few mnemonic key presses.
epkgs.magit
;; Add keybindings for working with `magit'. (dotfiles/leader "g" '(:ignore t :which-key "Git") "gg" '(magit-status :which-key "Status") "gc" '(magit-clone :which-key "Clone") "gf" '(magit-fetch :which-key "Fetch") "gp" '(magit-pull :which-key "Pull"))
Hydra
epkgs.hydra
Hydra allows you to create keymaps for related commands, with the ability to easily repeat commands using a single keystroke.
Fonts
Iosevka is an open-source, sans-serif + slab-serif, monospace + quasi-proportional typeface family, designed for writing code, using in terminals, and preparing technical documents. Configure it as the default font face inside of Emacs and define a Hydra command for quickly scaling text.
;; Configure the font when running as `emacs-server'.
(custom-set-faces
'(default ((t (:inherit nil :height 120 :family "Iosevka")))))
;; Define a `hydra' function for scaling the text interactively.
(defhydra hydra-text-scale (:timeout 4)
"Scale the text in the current buffer."

("f" nil "Finished" :exit t))
;; Create keybinding for calling the function.
(dotfiles/leader
"tf" '(hydra-text-scale/body :which-key "Font"))
Frames
Sometimes it's useful to resize the current frame without using the mouse (always). The default behaviour when calling shrink-window and enlarge-window only changes the size by a small margin. I solved this problem with the same method used for scaling text:
;; Define a `hydra' function for resizing the current frame.
(defhydra hydra-resize-frame (:timeout 4)
"Scale the current frame."
("h" shrink-window-horizontally "Left")
("j" enlarge-window "Down")
("k" shrink-window "Up")
("l" enlarge-window-horizontally "Right")
("f" nil "Finished" :exit t))
;; Add keybindings for working with frames to replace

Org Mode
epkgs.org
Org Mode is a document editing and organizing mode, designed for notes, planning, and authoring within the free software text editor GNU/Emacs.
