dotfiles

Personal toolchain (a nix flake) + config (symlinked from home/), set up via install.sh.

Install

git clone <repo> ~/dotfiles
cd ~/dotfiles && ./install.sh

install.sh:

1. Symlinks every file under home/ into the matching path in $HOME (relative symlinks, so the repo can be relocated).
2. Sets the default login shell to zsh if it isn't already.
3. Installs Determinate Nix if nix isn't on PATH.
4. Starts nix-daemon if it's not running (containers without systemd).
5. Installs the nix profile entry from this flake.

Idempotent — re-run safely after edits.

After first install, npm-based tools that aren't in nixpkgs:

npm install -g jj-stack @openai/codex

Day-to-day

just            # show available recipes
just upgrade    # bump pins (flake.lock) and rebuild
just packages   # list every tool with its resolved version
just rollback   # revert to previous nix profile generation
just edit       # open flake.nix in $EDITOR

Edit home/<...> files in place — they're symlinked, so $HOME edits are repo edits. The starship prompt shows a yellow ● when there are uncommitted changes here.

What's in the flake

• nixpkgs: cargo-binstall, delta, gh, go, jujutsu (jj), nodejs, starship, zellij.
• jj-domino — pulled from upstream flake (github:zombiezen/jj-domino), not nixpkgs.

Why this exists

Migrated off chezmoi + mise. Pattern based on https://github.com/jeremywmoore/dotfiles; context for the nix switch: https://gist.github.com/jeremywmoore/6c5a3349d1fa79ab474343c9f0feeab9.
