Iron-E's dotfiles

These are my dotfiles, written in Nix using home-manager. Derived from nix-starter-configs.

My old dotfiles can be found here.

Warning

Stability is not guaranteed for anyone but me, and breaking changes may arrive unannounced.

You may use this as a baseline for your own config, but it would be unwise to use it as a distribution!

Requirements

Requirements:

• dconf for home-manager activation script
• gcr for pinentry-gnome3 (for gpg-agent)
• nix for home-manager

Add these lines to your nix.conf:

experimental-features = nix-command flakes

Optional

Neovim

Optionally, to set up synchronization of the lazy.nvim lockfile to this repo, save this as a script and run it:

#!/usr/bin/env bash

# link rw nvim config into place
ROOT_PATH="$(git rev-parse --show-toplevel)/home-manager/hosts/_common_/programs+services/tui/neovim/config/read-write"
for dir in $(find -L "$ROOT_PATH" -mindepth 1 -maxdepth 1); do
	ln -sf "$dir" "$XDG_CONFIG_HOME/nvim/$(basename $dir)"
done

This step is performed automatically by the switch script.

Wezterm

On non-NixOS systems:

• wezterm-terminfo (or else wezterm looks weird)

xorg

On all systems:

• xauth (must be installed system-wide)
• xinit / startx (I don't use a display manager)

i3

On all systems:

• alsa-utils for volume control
• libpulse for volume control
• xsecurelock for lock screen (must be installed system-wide)

Usage

…as dotfiles

Use the switch script:

# one-time only
chmod +x ./switch.fish

# then print usage information
./switch.fish -h

Or, you can manually build a configuration:

# NOTE: `--impure` is required for `nixGL`. The rest of the configuration does not perform any impure action.
nix run .#home-manager --  build --impure --flake .#<user>@<hostname> --show-trace

…and then switch if you like its output:

# NOTE: `--impure` is required for `nixGL`. The rest of the configuration does not perform any impure action.
nix run .#home-manager -- switch -b pre-home-manager --impure --flake .#<user>@<hostname>

…as flake input

{
	inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable"; # or some other link
	inputs.dotfiles = {
		url = "github:Iron-E/dotfiles";
		inputs.nixpkgs.follows = "nixpkgs";
	};

	outputs = inputs @ { self, nixpkgs, dotfiles }: {
		# define outputs
	};
}

home-manager modules

This repository defines a homeManagerModules output, which can be used to access the home-manager modules (not the configs!) which are used by these dotfiles.

nixgl

An implementation of nix-community/nixGL#114 (comment).

Provides the options:

Name	Type	Default	Description
nixgl.prefix	str	""	Will be prepended to commands which are wrapped with nixGL. Should be set on non-NixOS systems.

Provides the outputs:

Name	Type	Description
config.lib.nixgl.prefix	pkg -> pkg	Can be used to wrap a package with nixGL. See the aforementioned issue comment.

Example:

{ inputs, outputs, config, lib, pkgs, ... }: {
	nixpkgs = { overlays = [inputs.nixgl.overlays.default]; }; # make sure `nixgl` is a flake input

	nixgl.prefix = lib.getExe' pkgs.nixgl.auto.nixGLDefault "nixGL";
	home.packages = [(config.lib.nixgl.wrap pkgs.wezterm)];
}

Hosts

The dotfiles provide a hosts output that is a path to the hosts directory in the nix store. This can be used to import the dotfiles in a NixOS config and integrate this standalone home-manager config into a home-manager NixOS module config.

Lib

The dotfiles provide a lib output, but:

• you'll have to read the source code (I'm not documenting the lib of my dotfiles, sorry!); and
• heed the warning at the top of this README.

Overlays

The dotfiles provide an overlays output.

Additions

The overlays.additions output is additional packages defined in this repository that can be overlayed onto nixpkgs.

Modifications

overlays.modifications which are customized existing nix packages.

nerdfonts-symbols

The nerdfonts nix package, with only symbols included.
