## Historique du projet et usages

brightness is a macOS command-line utility for reading and setting display brightness from scripts or the terminal.

### Historique du projet

The nriley/brightness repository was created in February 2014, with release 1.2 published in August 2015. The README describes a focused utility for controlling all internal and some external displays from the command line.

Its maintenance history mirrors macOS display API changes. The README notes that documented APIs worked through macOS 10.12.3, then Night Shift in 10.12.4 required an undocumented method, and Apple Silicon Macs later required another undocumented method.

### Historique d'adoption

brightness became a durable small utility for macOS automation users. It is packaged in Homebrew and MacPorts according to the input package facts, has hundreds of GitHub stars, and Homebrew analytics reported several thousand installs over the prior year at lookup time.

### Modes d'utilisation

Users run simple commands such as `brightness 1`, `brightness 0.5`, or `brightness -l` to set or list display brightness. The README cautions that displays not controllable through macOS Displays settings generally cannot be controlled by the tool either.

### Pourquoi les passionnés de paquets s'y intéressent

brightness is the archetypal tiny macOS system utility package: a single-purpose binary that exists because shell scripts and automation tools need access to a GUI-era hardware setting. Its significance is not breadth, but longevity across changing macOS display internals.

### Chronologie

- 2014: Repository created.
- 2015: Release 1.2 published.
- 2017: README documents the macOS 10.12.4 Night Shift-era API break and workaround.
- 2021: Repository history includes Universal 2 build work for Apple Silicon.
- 2026: Homebrew stable version reported as 1.2.

### Related projects

- Homebrew and MacPorts distribute brightness for macOS users.
- macOS display APIs and IOKit-style display enumeration are the system interfaces around which the utility operates.
- Shell scripts, launch agents, and automation workflows are common consumers of this kind of command-line brightness control.
