Dotfiles

Personal dotfiles and machine setup, managed with the rcm suite. Works on both Intel and Apple Silicon Macs.

New Machine Setup

git clone https://github.com/samcdavid/dotfiles.git ~/.dotfiles && ~/.dotfiles/setup/mac

This single command will:

1. Install Homebrew and all packages/casks
2. Symlink dotfiles via rcm
3. Authenticate with GitHub
4. Generate SSH and GPG keys
5. Set Fish as default shell
6. Install asdf plugins and language runtimes
7. Install Oh My Fish packages
8. Install Neovim plugins
9. Install tmux plugins
10. Configure macOS preferences and text replacements

Each run is logged to ~/laptop.log (auto-numbered on re-runs: laptop1.log, laptop2.log, etc.).

Manual Steps

• Set up 1Password before running the script

Environment

• Shell: Fish with Oh My Fish and 30+ custom functions
• Editor: Neovim with LazyVim framework
• Terminal: Ghostty + tmux with vim-like bindings and TPM
• Version Manager: asdf (Ruby, Node.js, Erlang, Elixir, Python, Go)
• VCS: Git with GPG and SSH key signing
