Dotfiles

My personal macOS setup. Brew is the source of truth for every CLI, GUI app, and plugin. macOS configuration and dotfile symlinks are managed by a small Makefile, with personal scripts in bin/.

Warning

These are tailored to my workflow (1Password for SSH/Git signing, Ghostty as terminal, Powerlevel10k, etc). Don't apply them blindly to your own machine.

Quick start

On a fresh Mac:

git clone git@github.com:limegorilla/dotfiles.git ~/.dotfiles
cd~/.dotfiles
make install

If you don't have git yet, the bootstrap script will install the Xcode Command Line Tools first; run make install again afterwards.

On an existing Mac, to re-apply everything safely:

dotfiles update # available once .zshrc is sourced# or, before the alias is loaded:
make -C ~/.dotfiles update

Makefile targets

Run make help for the live list. Highlights:

Target	What it does
make install	Bootstrap, brew, stow, fonts, macos, apps (first run)
make update	Re-apply everything (safe to repeat on existing Macs)
make brew	brew bundle against the Brewfile
make brew-dump	Overwrite Brewfile with current brew state (review!)
make stow	Symlink home/ into $HOME
make restow	Re-create symlinks (after pulling changes, for example)
make fonts	Copy bundled fonts into ~/Library/Fonts
make macos	defaults.sh + dock.sh
make apps	apps.sh
make doctor	Sanity-check the environment

Once .zshrc is sourced, the same targets are available via the dotfiles alias (e.g. dotfiles update, dotfiles doctor), which also exposes the richer adopt subcommands below.

dotfiles adopt

dotfiles adopt brings an existing local resource into this repo. The mode flag is required — there is no default — so the destructive file case can never run by accident.

Command	What it does
dotfiles adopt --file	stow --adopt files from $HOME into home/
dotfiles adopt --brew	Pick installed formulae/casks to track in the Brewfile
dotfiles adopt --brew NAME	Install a formula (if needed) and track it
dotfiles adopt --brew --cask NAME	Same, for a cask
dotfiles adopt --mas	Pick installed Mac App Store apps to track
dotfiles adopt --mas QUERY	Search the App Store, pick one, install + track

Adopted Brewfile entries land in a flat # Adopted section at the end of the file. The script verifies the Brewfile with brew bundle check after every mutation and prompts you to commit (with a default adopt: message) before exiting.

The bin/ directory

Anything in bin/ is on $PATH after the shell is sourced. Add a new script by dropping a file in, marking it executable, and starting it with a useful shebang (#!/usr/bin/env bash for shell, etc.).

eod — end-of-day report

Walks every git repository under ~/Developer and lists anything with uncommitted changes, unpushed commits, or no upstream branch. Run it before shutting down for the day:

eod # scans ~/Developer
eod ~/code # scan a different tree

Conventions

• Every package is installed via Brew or the Mac App Store. Manual installs (curl | bash, npm i -g, ...) belong in a script, not in folklore.
• Every setup script is idempotent. Re-running make update on an existing Mac should never break the system or require manual cleanup.
• macOS-only. No if linux branches. If that changes, introduce linux/defaults.sh and split the Makefile targets.

Adopting on an existing Mac

If you already have a ~/.zshrc, ~/.gitconfig, etc., make stow will refuse to overwrite them. Two options:

1. Back them up, delete them, and make stow.
2. Run dotfiles adopt --file to move the existing files into home/, then review the diff and reset anything you don't actually want to track.
