Show HN: SpacePigeon – a macOS workspace automation tool built on Hammerspoon

SpacePigeon lets you define workspaces for macOS — which apps open, which desktop spaces they go to, and how windows are arranged — using a single simple init.lua script for Hammerspoon.

• Open specific apps into specific macOS Spaces
• Auto-arrange windows
• Trigger workspaces via hotkeys
• Written entirely in Hammerspoon Lua
• Lightweight and open-source

1. Install Hammerspoon
2. Copy init.lua into your ~/.hammerspoon directory
3. Reload Hammerspoon

This is an early open-source release.
More modular structure, documentation, and GUI tools are coming soon.
