dotfiles

Personal machine setup – idempotent, safe to re-run at any time.

Setup

git clone https://github.com/janmarkuslanger/dotfiles.git ~/dotfiles
cd ~/dotfiles
./setup.sh

The script prompts interactively which steps to run:

Step	What it does
1. Homebrew	Installs Homebrew (if missing) + all packages from Brewfile
2. Apps	Installs global npm tools (Claude Code)
3. Copy	Copies dotfiles into $HOME, prompts on conflict

zsh	~/.zshrc	Aliases, PATH, fzf, zoxide, history

Conflict handling

When a file already exists at the target location and differs from the source, the script asks:

[copy] ~/.zshrc already exists.
       [o] overwrite  [b] backup + overwrite  [s] skip (default) :

Adding a new dotfile package

1. Create a directory mirroring the target path relative to $HOME:

   git/.gitconfig
   

2. Add the package name to PACKAGES in scripts/03_copy.sh
3. Re-run ./setup.sh (step 3 only)

Adding a new brew package

Edit Brewfile, then:

brew bundle --file=Brewfile --no-lock
