Personal macOS dev environment — zsh config, git aliases, and a Mac bootstrap script.

What's in here

File	Purpose
.zsh_extras.sh	Shell prompt, aliases, and utility functions — source this from ~/.zshrc
.gitconfig	Git aliases, colors, and URL shorthands
.gitignore	Global gitignore
.gitattributes	Global gitattributes
.inputrc	Readline settings (case-insensitive completion, smart history search)
.vimrc / .vim/	Vim config
.wgetrc	wget defaults
.hushlogin	Suppress the "Last login" message in new terminal tabs
setup.sh	Full Mac dev environment bootstrap (see below)

Setup on a new Mac

git clone https://github.com/alfasin/dotfiles.git ~/dev/dotfiles

Shell config

Add to the bottom of ~/.zshrc:

[ -f "$HOME/dev/dotfiles/.zsh_extras.sh" ] && source "$HOME/dev/dotfiles/.zsh_extras.sh"

This gives you:

• A clean prompt showing current directory and git branch (with * when there are uncommitted changes)
• Navigation aliases (.., ..., ....)
• ll, la, lsd — ls shortcuts
• c — pipe anything into it to strip trailing newline and copy to clipboard
• mkd — mkdir + cd in one step
• calc — terminal calculator (calc 3.14 * 2)
• digga — all DNS records for a domain
• getcertnames / opensslcheckexpiration — TLS cert inspection
• diff — uses git's color-word diff instead of plain diff
• And more — see the file for the full list

Git config

Copy or symlink .gitconfig to ~/.gitconfig. Notable aliases:

Alias	What it does
git l	Pretty graph log (last 20 commits)
git go <branch>	Create or switch to branch
git reb 3	Interactive rebase last N commits
git fb <sha>	Find branches containing a commit
git fc <string>	Find commits that added/removed a string
git fm <text>	Find commits by message
git di 2	Diff against N revisions back

URL shorthand — clone with gh: instead of the full GitHub URL:

git clone gh:alfasin/dotfiles

Bootstrap a new Mac from scratch

setup.sh is an idempotent bootstrap for a fresh Mac. It installs everything needed to get a dev environment running. Safe to re-run — each step checks before acting. A failed item is recorded and skipped without stopping the rest.

cd ~/dev/dotfiles && zsh setup.sh

What it installs:

• Xcode Command Line Tools
• Homebrew
• CLI tools: git, gh, awscli, nvm, uv, ripgrep, fd
• GUI apps: Warp, VS Code, OrbStack, Bitwarden, pgAdmin 4, Alfred, SizeUp
• Node LTS (via nvm)
• Claude Code + plugins (superpowers, feature-dev, code-review, code-simplifier, typescript-lsp)

After it finishes, a few manual steps remain (printed at the end):

• Restart the terminal
• Open OrbStack once to finish VM backend setup
• gh auth login
• Sign into Bitwarden
• Copy over ~/.claude/ memory from old machine if migrating
