KissNeighbor

A macOS utility that instantly resizes the frontmost window to extend rightward until it touches the next adjacent window.

What it does

KissNeighbor uses the Accessibility API to:

  1. Find the frontmost application window
  2. Locate the nearest window to the right that overlaps vertically
  3. Resize the frontmost window to extend right and "kiss" (touch) that neighbor window

Perfect for quick window tiling without manual resizing.

Quick Setup

1. Compile the binary

cd~/Documents/GitHub/KissNeighbor
chmod +x build.sh
./build.sh

2. Grant Accessibility Permissions

System Settings → Privacy & Security → Accessibility → Add Hammerspoon

3. Install & Configure Hammerspoon

# Install Hammerspoon
brew install hammerspoon
# The config is already created at ~/.hammerspoon/init.lua# Just open Hammerspoon from Applications
open /Applications/Hammerspoon.app

4. Done!

Press Cmd+Shift+K anytime to extend the active window right. No UI, instant execution.

How it works

  • Compiled Objective-C binary for instant execution (~5ms)
  • Hammerspoon runs in background as a daemon
  • Responds instantly to global hotkeys with zero delay
  • No UI popups, completely silent

Files

  • kissneighbor.m - Objective-C source
  • build.sh - Compilation script
  • kissneighbor - Compiled binary (generated)
  • ~/.hammerspoon/init.lua - Hammerspoon config
