The README describes it as a personal GPLv3 utility in maintenance mode rather than a broad support forum. ### Projektgeschichte The GitHub repository was created in August 2014. Its README says ddcctl.m sprang from a TonyMac-x86 forum thread and that DDC.c originated from jontaylor/DDC-CI-Tools-for-OS-X before being reworked by others. ### Adoptionsgeschichte ddcctl found a durable packaging niche because macOS users with external monitors often wanted scriptable brightness and input control. The README documents Homebrew installation first, followed by release binaries and building from source. ### Wie es verwendet wird Users run ddcctl from the shell to adjust display controls such as brightness, contrast, input source, volume, RGB values, and presets when the monitor firmware supports them. The README also points to an example script for controlling two monitors from a Mac mini. ### Warum Paket-Nerds sich dafür interessieren For package nerds, ddcctl is the kind of hardware-adjacent CLI that earns a formula because it bridges a small OS capability gap. It is tiny, platform-specific, and useful precisely because it makes display controls scriptable. ### Zeitleiste - 2014: GitHub repository created - 2021: v0 release published - 2022: v1 release published ### Related projects - DDC-CI-Tools-for-OS-X, ddccontrol, monitorcontrol ### Quellen - - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ddcctl - **Version Scheme:** 0 - **Revision:** 0 - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - MacPorts - ddcctl: normalized package name match | MacPorts ports tree: sysutils/ddcctl/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Verwandte Links - [Source-control packages](https://pkg.so/de/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://pkg.so/de/brew-utility-packages/) - Matched Homebrew package provider. - [ddcutil](https://pkg.so/de/brew/ddcutil/) - Shares pkgdb curated category or tags: brightness, cli, display-control, monitor, system. - [displayplacer](https://pkg.so/de/brew/displayplacer/) - Shares pkgdb curated category or tags: cli, macos, monitor, system. - [brightness](https://pkg.so/de/brew/brightness/) - Shares pkgdb curated category or tags: brightness, cli, macos, system. - [m1ddc](https://pkg.so/de/brew/m1ddc/) - Shares pkgdb curated category or tags: cli, display-control, macos, system. - [mole](https://pkg.so/de/brew/mole/) - Shares pkgdb curated category or tags: cli, macos, system. - [lima](https://pkg.so/de/brew/lima/) - Shares pkgdb curated category or tags: cli, macos, system. - [mas](https://pkg.so/de/brew/mas/) - Shares pkgdb curated category or tags: cli, macos, system. - [terminal-notifier](https://pkg.so/de/brew/terminal-notifier/) - Shares pkgdb curated category or tags: cli, macos, system. - [dark-mode](https://pkg.so/de/brew/dark-mode/) - Local package facts share a topical domain.
