tmux Configuration

My personal tmux configuration — a productive terminal multiplexer setup tuned for macOS (and usable on Linux) with a clean Ghostty-inspired dark theme, vi-style keybindings, and a hand-picked set of plugins managed by TPM.

Features

• Ghostty-inspired dark color scheme
• Vi-style copy mode with system clipboard integration
• Mouse support enabled
• True color (24-bit) support for modern terminals
• Session persistence (resurrect: manual save/restore)
• Fuzzy search across scrollback, URLs, and terminal output
• Sidebar directory tree, copycat search, and a command palette

---

Requirements

• tmux ≥ 3.2
• TPM — Tmux Plugin Manager
• fzf — required by several plugins
• macOS: reattach-to-user-namespace (brew install reattach-to-user-namespace)
• Linux: xclip or wl-copy for clipboard integration

---

Installation

One-liner

curl -fsSL https://raw.githubusercontent.com/bastos/dot-tmux/main/install.sh | bash

The script will:

• Back up any existing ~/.config/tmux directory
• Clone this repo into ~/.config/tmux
• Install TPM and all plugins
• Install reattach-to-user-namespace on macOS (requires Homebrew)
• Install fzf automatically (Homebrew on macOS; apt / pacman / dnf on Linux)

Then just start tmux:

tmux
