Lunar is a macOS-focused application designed to improve control over external monitors by intelligently adjusting brightness and other display settings. Instead of applying a software brightness overlay, it directly communicates with compatible displays using the DDC/CI hardware protocol, offering true hardware-level brightness adjustments when supported. Lunar doesn’t just adjust brightness. It intelligently adapts to environmental conditions by using external or built-in ambient light sensors and location-based cues like sunrise and sunset times. Users can fine-tune many aspects of their displays, including volume, contrast, screen orientation, and input switching, all through native macOS interfaces or customizable hotkeys. The tool also includes advanced features such as dimming below 0% for low-light conditions and blackout controls that power off screens without disrupting connected hardware.

This is a tool for powerful automation of OS X. At its core, Hammerspoon is just a bridge between the operating system and a Lua scripting engine. What gives Hammerspoon its power is a set of extensions that expose specific pieces of system functionality, to the user. You can write Lua code that interacts with OS X APIs for applications, windows, mouse pointers, filesystem objects, audio devices, batteries, screens, low-level keyboard/mouse events, clipboards, location services, wifi, and more. Typically you would write a configuration file in Lua that connects events to actions. You might want to bind a keyboard shortcut to a series of window operations, or an applescript. You might want to run a series of commands when your wifi interface connects to your home network. You might want to display an alert when your battery drops below a certain percentage. You might want to do something crazy like have iTunes automatically start playing when your Mac detects you are in Paris.
