dotfiles

My macOS dotfiles, stored as a bare git repo in ~/.cfg with $HOME as the work tree (how it works).

What	Path
Neovim (LazyVim)	.config/nvim/ (README)
tmux	.tmux.conf
zsh + powerlevel10k	.zshrc, .zprofile, .p10k.zsh
Homebrew (minimal)	.homebrew/work/Brewfile (work / temporary machines)
Homebrew (full)	.homebrew/personal/Brewfile (personal machines)
Claude Code settings	.claude/settings.json

Install on a new machine

# 1. Homebrew, then oh-my-zsh (+ zsh-syntax-highlighting, zsh-autosuggestions plugins)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
git clone https://github.com/zsh-users/zsh-syntax-highlighting ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting
git clone https://github.com/zsh-users/zsh-autosuggestions ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions

# 2. Dotfiles
git clone --bare git@github.com:nulcell/dotfiles.git $HOME/.cfg
alias config='/usr/bin/git --git-dir=$HOME/.cfg/ --work-tree=$HOME'
config checkout
# If checkout complains about existing files, back them up and retry:
#   mkdir -p .config-backup && config checkout 2>&1 | grep -E "^\s+" | awk '{print $1}' | xargs -I{} sh -c 'mkdir -p .config-backup/$(dirname {}) && mv {} .config-backup/{}'
#   config checkout
config config --local status.showUntrackedFiles no

# 3. Packages: pick one (see "Homebrew" below)
brew bundle --file ~/.homebrew/work/Brewfile      # minimal CLI set
brew bundle --file ~/.homebrew/personal/Brewfile  # everything: apps, VS Code extensions, etc.

# 4. tmux plugins: start tmux, then press prefix + I
git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm

Neovim installs its plugins on first launch.

Day to day

config is plain git pointed at ~/.cfg:

config status
config add .config/kitty/kitty.conf   # start tracking a new file
config commit -m "..." && config push

Homebrew

Two Brewfiles, one per machine type. Set BF to the one this machine uses:

BF=~/.homebrew/work/Brewfile       # work / temporary machines
BF=~/.homebrew/personal/Brewfile   # personal machines

Task	Command
Install missing + upgrade outdated	brew update && brew bundle --file $BF
Check whether anything is missing	brew bundle check --file $BF --verbose
List installed packages not in the Brewfile	brew bundle cleanup --file $BF
Uninstall those packages	brew bundle cleanup --file $BF --force
Add a package	brew install <pkg>, then regenerate (below)

Regenerate a Brewfile from what's installed, then review config diff before committing:

# work: CLI tools only
brew bundle dump --file ~/.homebrew/work/Brewfile --no-cask --no-vscode --no-go --no-npm --no-restart --force
# personal: everything
brew bundle dump --file ~/.homebrew/personal/Brewfile --no-go --force

Regenerating the work Brewfile on a personal machine pulls in every CLI tool installed there, so trim the diff before committing.
