TOFU

An ultra-minimalist application launcher for Wayland, inspired by rofi and dmenu.

Features

• Tiny: ~750 lines of Rust, ~1MB binary
• Fast: Native Wayland layer-shell, no X11 overhead
• Fuzzy matching: Skim's algorithm for fast filtering
• Beautiful: Fade-out results, rounded corners, customizable accent colors
• Flexible: dmenu mode or .desktop app launcher

Installation

just install

Requires ~/.local/bin in your PATH.

Usage

Basic Modes

dmenu mode (read from stdin):

Visual Design

• Centered: Appears on the output with keyboard focus
• Rounded corners: 12px radius on main container
• Fade effect: Lower results fade to black (minimum 20% opacity)
• Block cursor: Solid block instead of line
• Clipped: Results stay within rounded container
• Two selection styles:
  • Normal: Accent color background, white text
  • Inverted (--invert): Black background, accent color text
