dotfiles

my system configs managed with nix flakes. handles both nixos (mandelbrot) and nix-darwin (macbook).

what's here

• nix/ - system configurations for each machine
  • mandelbrot/ - nixos desktop (nvidia gpu, niri compositor, ollama server)
  • Alexs-Macbook-Pro/ - nix-darwin config for macos
  • common/ - shared configuration between systems
• config/ - dotfiles for various programs
  • fish/ - shell config with custom functions and completions
  • nvim/ - neovim setup
  • ghostty/ - terminal emulator config
  • yazi/ - file manager with tokyo-night theme
  • starship.toml - prompt config
  • niri/ - compositor config (nixos only)
  • rofi/ - launcher/menu system
  • gh/, gopass/, argocd/, zed/ - tool configs
• fonts/ - GoMono nerd font
• scripts/ - utility scripts (aws helpers, git, hyprpaper, etc)
• flake.nix - defines all systems and their dependencies

systems

mandelbrot (nixos)

• niri compositor with nvidia prime offload
• ollama serving on tailnet (gpu accelerated)
• steam, bluetooth, pipewire audio
• auto-login to greeter

macbook (nix-darwin)

• homebrew integration for gui apps and missing packages
• most cli tools via nix
• ghostty, zed, vscode, spotify, etc via casks

managed configs

both systems use home-manager to symlink configs from this repo:

• fish shell (aliases, functions, paths, env vars)
• neovim with treesitter, packer
• git config (gpg signing, user info)
• tmux, starship, yazi, jq, fd, fzf, go
• ghostty with custom colorscheme

setup

see setup.md for full details. nix-based setup is:

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

# get secrets from bitwarden (ssh keys, gpg)
# see setup.md

# for nixos:
sudo nixos-rebuild switch --flake github:Briansbum/dotfiles#mandelbrot

# for macos:
darwin-rebuild switch --flake github:Briansbum/dotfiles#Alexs-MacBook-Pro

updating

the correct way (declarative, pulls from git):

# make changes, commit, push to github

# for nixos:
sudo nixos-rebuild switch --flake github:Briansbum/dotfiles#mandelbrot --refresh

# for macos:
darwin-rebuild switch --flake github:Briansbum/dotfiles#Alexs-MacBook-Pro --refresh

fast method for local testing (impure):

cd ~/devel/dotfiles

# for nixos:
sudo nixos-rebuild switch --flake .#mandelbrot

# for macos:
darwin-rebuild switch --flake .#Alexs-MacBook-Pro
