Touchpaddy

Cross-platform (wip) libinput touchpad gesture bindings for Linux, especially for KDE Plasma (6)!

Features

Two finger forward/back in web browsers

A quick two-finger horizontal "scroll" should prompt back/forwards in Firefox, Edge, and Chromium-based web browsers.

Three finger gestures

swipe left-right to Alt-Tab between open windows
swipe up to view the task view/present windows/grid display view like Windows + Tab on Windows
swipe down to minimize all active windows (manually minimizes them with kwin, doesn't do the Meta + D Plasma keybind)

Four finger gestures

swipe left-right to quickly snap the active window to the left and right respectively
swipe down to minimize the active window (conflicts with hardcoded Plasma 6 gestures in Wayland :/)
swipe up to maximize the active window (conflicts with hardcoded Plasma 6 gestures in Wayland :/)

Gestures are defined in ./src/gestures.luau; please feel free to add more gestures and if you have some good ones, PR them in!

Dependencies

Cargo to build Lune
The Lune runtime for Luau; requires the lune-process-stream PR: https://github.com/0x5eal/lune-process-stream
yad for gui dialogs
screen to run in background
kdotool (for KDE Plasma 6)
ydotool (for both X11 and Wayland)

Install

ensure you have dependencies installed, including Cargo to build Rust projects, yad, screen, kdotool, and ydotool. You can install these from your favorite package manager.
clone and build lunestream with cargo build --release
add lunestream to your PATH
run touchpaddy with lunestream run path_to_touchpaddy or ./path_to_touchpaddy/init.luau, whichever works

Install script and QoL improvements forthcoming.
