Configs under Nix and Home Manager

An attempt at a unified and cross-platform environment.

Setup

Setting up Nix

Under NixOS ensure that you have gcc and unzip installed.

Under MacOS, install Nix:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

This installs Nix using the Determinate Systems installer.

Setting up Home Manager with this config

  • Clone this repo. If you don't you have git installed you can use nix to run it once-off: nix run nixpkgs#git -- clone https://github.com/allank/dotfiles
  • Run ./mklocal.sh - this should copy the base flake.nix and home.nix into the root directory of the repo and personalise for your current user and system.
  • In this repo run: nix run github:nix-community/home-manager -- switch --flake .

Note:

The mklocal.sh script is a messy hack so that I can have a single set of config files for multiple operating systems and architectures. While there does seem to be ways of doing conditional settings within the home.nix file, they do not apper to be available within flake.nix. If there is a less messy way of handling this, please let me know.

Currently under Darwin the Home Manager install tries to compile wezterm and fails. The mklocal.sh script currently comments out the wezterm package until I can add a more elegant workaround.

Usage

Using Nix and Home Manager

  • Rebuilding your environment: home-manager -- switch --flake .
  • Garbage collecting old configurations: sudo nix-collect-garbage -d
  • Running a new appliction without installing: nix-shell -p neofetch
