Dotfiles (Nix + Home Manager)

This repo defines my user environment via Home Manager.
It works on Ubuntu (WSL2) with flakes enabled.

---

Quickstart (new machine)

1. Install Nix (multi-user, with flakes):

   sh <(curl -L https://nixos.org/nix/install) --daemon
   echo 'experimental-features = nix-command flakes' | sudo tee -a /etc/nix/nix.conf

2. Clone repo into Home Manager config dir:

   git clone https://github.com/pkuehne/dotfiles.git ~/.config/home-manager

3. Install Home Manager:

   nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
   nix-channel --update
   nix-shell '<home-manager>' -A install

4. Activate (choose profile):

   home-manager switch --flake ~/.config/home-manager#home
   # or
   home-manager switch --flake ~/.config/home-manager#work

5. Set Zsh as login shell:

   echo "$HOME/.nix-profile/bin/zsh" | sudo tee -a /etc/shells
   chsh -s "$HOME/.nix-profile/bin/zsh"

6. Restart WSL / shell:

   exec zsh -l

Layout

flake.nix        # Entrypoint, defines profiles (home, work)
flake.lock       # Version pins (commit to repo!)
modules/
  common.nix     # Shared config (packages, basics)
  zsh.nix        # Zsh setup (plugins, aliases)
  p10k.nix       # Powerlevel10k config (theme, prompt)
  work.nix       # Work-only overrides (no secrets!)

---

Notes

• Secrets are not in this repo (.ssh/config, proxies, corp repos, etc.).
• Profiles:
  • home = personal config
  • work = minimal safe config for corp machines
• Fonts: use a Nerd Font (e.g. FiraCode NF) in your terminal for Powerlevel10k glyphs. ~/.nix-profile.

Updating

Update inputs (nixpkgs, home-manager):

nix flake update
home-manager switch --flake ~/.config/home-manager#home

---

Troubleshooting

• If home-manager command is missing:

  nix run github:nix-community/home-manager/release-<version> -- switch --flake ~/.config/home-manager#home

• If Zsh doesn't start automatically in WSL, set the shell in Windows Terminal profile:

    Command line: wsl.exe -d <DistroName> -- zsh
