— UPDATE: This is sorely out of date. I have maintained all my Nix and Emacs config using a literate Org file for the last couple of years. I plan to tidy up the private parts and publish… at some point. —
Welcome to the bikeshed!
This repository houses all my machine configurations expressed declaratively using a Nix flake. It covers both my personal and work devices that are running either NixOS or macOS.
The expressions are organised into platform-agnostic modules that leverage the likes of the nixpkgs, home-manager and nix-darwin to fully configure the OS and userspace from scratch.
These days I am spending the majority of time in either Firefox or Emacs (+vterm). On NixOS I am using EXWM and on macOS I am usually just running native fullscreen, ⌘↹ing between the two previously mentioned apps. Additionally, a simple theming system is used to switch various things between light and dark versions, and a secrets attribute set (kept encrypted in a private repository) is referenced throughout.
NOTE: Some twisted souls found value in all the ricing of the previous incarnation of this repository. I’ll keep archived on this branch for reference.
CI (Travis for NixOS, GitHub Actions for macOS) runs on push. The jobs generate a special CI machine that imports every module, and derives either a NixOS VM (via QEMU) or simply builds on a fresh Darwin agent VM (in the case of macOS). The resultant binaries are pushed to Cachix and subsequently become available for any of my other machines, saving a lot of wasted battery!
The Makefile (in conjunction with some helpful aliases) is used to drive most actions, abstracting away NixOS/macOS differences where necessary.
Below are some rough platform specific installation notes I use to go from fresh installs to fully configured machine.
From a fresh macOS install.
