Dev Environment Setup

Template for Part 1 of the setup script. All steps are idempotent.

Homebrew PATH

if ! grep -q 'brew shellenv' ~/.zprofile 2>/dev/null; then
  echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
fi
eval "$(/opt/homebrew/bin/brew shellenv)"

Packages

Install via brew (skip if present):

for pkg in neovim tmux git starship gh node; do
  if brew list "$pkg" &>/dev/null; then
    echo "  $pkg: installed"
  else
    brew install "$pkg"
  fi
done

Bun via official installer (not in Homebrew):

if [ -x ~/.bun/bin/bun ]; then
  echo "  bun: installed"
else
  curl -fsSL https://bun.sh/install | bash
fi

Nvim Config

Clone Nicholai's config from Gitea:

if [ -d ~/.config/nvim/.git ]; then
  echo "already cloned"
else
  mkdir -p ~/.config
  git clone https://git.nicholai.work/Nicholai/nvim.git ~/.config/nvim
fi

config.json

Generate if not present. Adapt paths per machine (Mac uses ~/Documents/, ~/Developer/, etc.). Template:

{
    "paths": {
        "obsidianVault": "~/Documents/obsidian-vault/",
        "srcDirectory": "~/Developer/",
        "scriptsDirectory": "~/scripts/",
        "wallpaperScript": "~/scripts/pywal/wallpapermenu.sh"
    },
    "editor": {
        "tabSize": 4,
        "scrollOffset": 8,
        "theme": "wave"
    },
    "ai": {
        "model": "claude-sonnet-4-5",
        "openCodeModel": "anthropic/claude-sonnet-4-5"
    },
    "lsp": {
        "servers": ["ts_ls", "eslint", "jsonls", "html", "cssls", "tailwindcss"]
    },
    "treesitter": {
        "languages": ["lua", "vim", "bash", "javascript", "typescript", "tsx", "json", "yaml", "html", "css"]
    }
}

Dotfile Symlinks

ln -sf ~/.config/nvim/dotfiles/.tmux.conf ~/.tmux.conf
ln -sf ~/.config/nvim/dotfiles/starship.toml ~/.config/starship.toml

Nvim Plugins

nvim --headless "+Lazy! sync" +qa 2>/dev/null || true

Shell Aliases

Append to ~/.zshrc if not already present (check for marker comment # Added by nvim dotfiles setup). Include:

Git shortcuts: gs, ga, gc, gp, gl
Claude aliases: cldy, cldyh, cldys, cldyo
Directory aliases: .., ..., ...., home, cd.., chpwd, mkdirg
Editor: EDITOR=nvim, VISUAL=nvim, alias vim=nvim
Prompt: eval "$(starship init zsh)"

tmux Terminal Fix

Ensure tmux.conf has this line for backspace over SSH:

set -ga terminal-overrides ",*:Tc,*:kbs=\177"
