Dotfiles

Prerequisites

• Homebrew
• JetbrainsMono Nerd Font

Get dotfiles setup on another machine:

alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'
git clone --bare https://github.com/leviFrosty/dotfiles.git $HOME/.dotfiles
dotfiles config --local status.showUntrackedFiles no
dotfiles checkout
brew bundle --file=~/Brewfile
source ~/.zshrc

Aside: how to open Lazygit in dotfiles bare git repo

lazygit --git-dir=$HOME/.dotfiles --work-tree=$HOME

If some of the dotfiles are already present, you will see errors.

error: The following untracked working tree files would be overwritten by checkout:
 .bashrc
Please move or remove them before you switch branches.
Aborting

Remove or backup any collisions and repeat the checkout

mv ~/.zshrc ~/.zshrc_backup
dotfiles checkout

Add new files to dotfiles

dotfiles add ~/.config/aerospace/**
dotfiles push

Syncing from other machine

dotfiles pull

Dump brew bundle into a file

brew bundle dump --describe --file=~/Brewfile --force

Install brew bundle

brew bundle --file=~/Brewfile

Install Sketchybar from FelixKratz (No longer used)

Due to visual conflicts with the native MacOS menu bar, I removed Sketchybar. I have the MacOS menu bar set to autohide.

tmux

A work command launches the project's dev workstation: editor + a tmux session full of dev servers, all configured per-project by a work.yml. Session orchestration is handled by smug. Custom config is in ~/.tmux.conf; the launcher is ~/.local/bin/work.

Setup (new machine)

brew install tmux smug
# Ensure ~/.local/bin is on PATH (it's already on this machine; verify on a new one):
echo $PATH | tr ':' '\n' | grep -qx "$HOME/.local/bin" || echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc

Set up a new project

In any project that doesn't yet have a work.yml:

cd ~/dev/some-project
work

When prompted, accept (default Y) to launch Claude Code with the /create-work-yml skill — it explores the repo, asks intent questions, and writes work.yml for you.

To run the skill manually inside an existing Claude session:

/create-work-yml

Daily use

work                            # opens editor + attaches/starts the tmux session for this project
tmux ls                         # list active tmux sessions
tmux a -t <session>             # attach by name
tmux kill-session -t <session>  # kill one session
tmux kill-server                # nuke everything (use after tmux config changes if `prefix r` won't suffice)

Keybindings

Prefix is Ctrl-b. Custom bindings live in ~/.tmux.conf. Reload after edits with prefix r.

Pane navigation (vim hjkl)

Keys	Action
prefix h / j / k / l	Focus pane left / down / up / right
prefix o	Cycle to next pane
prefix q then digit	Show pane numbers, jump to one
prefix z	Zoom (fullscreen) toggle on current pane

Pane resize (vim HJKL — repeatable; hold prefix and tap)

Keys	Action
prefix H / J / K / L	Resize pane left / down / up / right by 5 cells

Splits (open in current pane's directory)

Keys	Action
prefix |	Split vertical (left / right)
prefix -	Split horizontal (top / bottom)
prefix x	Kill current pane (confirms)

Windows

Keys	Action
prefix n	New window (inherits cwd) — was next-window by default
prefix a	Previous window
prefix b	Next window — was send-prefix by default
prefix 0..9	Jump to window by number
prefix ,	Rename current window
prefix w	Window picker
prefix Tab	Last-used window — was prefix l by default
prefix &	Kill current window (confirms)
prefix C-b	Send literal prefix to nested app (relocated from prefix b)

prefix c and prefix p are intentionally unbound so muscle memory points at the new layout.

Sessions

Keys / Command	Action
prefix d	Detach (session keeps running in the background)
prefix s	Session picker
prefix $	Rename current session
tmux ls	List sessions (from shell)
tmux a -t <name>	Attach (from shell)
tmux kill-session -t <name>	Kill one session
tmux kill-server	Kill every session and the tmux daemon

Copy mode (vim-style)

Keys	Action
prefix [	Enter copy mode
v	Start selection
Ctrl-v	Toggle rectangular selection
y	Copy + exit; pipes through pbcopy so the system clipboard gets it
q or Esc	Exit copy mode

Misc

Keys	Action
prefix r	Reload ~/.tmux.conf
prefix ?	Show every key binding
prefix :	Tmux command prompt (e.g. :source-file ~/.tmux.conf)

Editing work.yml — pane-count gotcha

Smug auto-creates one starter pane per window. Window-level commands: runs in that starter pane; entries in panes: add additional panes on top. So N services → window commands: for service #1 + (N-1) entries in panes:. Putting all N in panes: produces N+1 panes (one empty starter shell at the top).
