tmux, zsh, git, etc. Neovim config is separate: https://github.com/cmdcolin/mysetup.nvim

install

./install.sh         # Auto-detects OS
./install.sh mac     # macOS
./install.sh ubuntu  # Ubuntu/Linux

Or just link configs without installing packages:

./link.sh

tmux

Prefix is C-]. Splits:

C-] = — split side-by-side
C-] - — split stacked

nested tmux (e.g. ssh'd into a server)

The local tmux eats the prefix first, so hit it twice to pass it through to the remote session (bind C-] send-prefix):

C-] C-] = — split the remote tmux side-by-side
C-] C-] - — split the remote tmux stacked

clipboard

Copying (drag-select, y, or Enter in copy mode) always targets the clipboard of the machine you're sitting at, including from a tmux on a remote box: alongside pbcopy/xclip, tmux emits an OSC 52 escape sequence that the local terminal turns into a clipboard write. No X11 forwarding needed. This relies on set -g set-clipboard on — the default external makes a local tmux swallow a nested remote tmux's sequence instead of relaying it.

Requires a terminal with OSC 52 enabled (iTerm2, WezTerm, Ghostty, kitty, Alacritty, foot; iTerm2 needs Allow clipboard access to terminal apps). Apple Terminal.app does not support it.

Pasting is just the terminal's own paste (Cmd-V / Ctrl-Shift-V) — it types the local clipboard into the remote shell. Terminals can't be read back over OSC 52, so there's no way to pull the local clipboard into a remote pbpaste.

setup

Machine: Dell laptop 32gb/512GB (primary), MacBook Pro (secondary)
OS: Ubuntu 24.10 / macOS
Editor: neovim (kickstart.nvim)
Browser: Firefox + Dark Reader + uBlock
Music: fml9000 or ytshuffle

Some keybindings are set up to avoid RSI — lots of double-tap commands to avoid hand contortion. More here: https://cmdcolin.github.io/posts/2022-07-08-pinky
