dotfiles

Personal dotfiles managed with Dotbot.

What's included

File	Description
zshrc	Zsh config with Oh My Zsh, Powerlevel10k, and performance optimizations
vimrc	Vim configuration

Installation

git clone https://github.com/YOUR_USERNAME/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
./install

This will symlink the config files to your home directory.

Dependencies

Install these before running:

# macOS (Homebrew)
brew install zsh-autosuggestions zsh-syntax-highlighting powerlevel10k
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Updating

cd ~/.dotfiles
git pull
./install

Re-running install

The install script is idempotent—run it anytime to sync changes:

./install

Shell startup performance

Oh My Zsh initializes completions once, including its cache invalidation and permission checks. Register Homebrew's completion directory before loading it, preserve inherited completion-path order, and keep both PATH and FPATH unique. Load zsh/complist before initialization to preserve the completion-menu widget. Running compinit again afterwards adds startup work and clears plugin completion registrations.

On this Mac, nine-run median startup times measured in a pseudo-terminal were:

Shell	Before	After
Interactive zsh (zsh -ic 'exit 0')	117 ms	67 ms
Login interactive zsh (zsh -lic 'exit 0')	123 ms	84 ms

Bash and sh had no personal startup configuration and already started in a few milliseconds. These are full initialization timings, not time to the instant prompt; timings vary with system load and cache state.

Validation covered aliases, shell options, PATH order, completion registrations, ZLE widgets, prompt/plugins, nested-shell cache reuse, real Tab completion, and lazy Conda activation/deactivation. Bun and OpenCode settings remain enabled.

To spot-check startup from an existing terminal:

/usr/bin/time /bin/zsh -ic 'exit 0'
/usr/bin/time /bin/zsh -lic 'exit 0'
