JaderoChan/global_hotkey

Global Hotkey is a promising small C++ library because it tackles a real desktop-app pain point: registering global shortcuts across Windows, macOS, and Linux without tying the user to Qt, MFC, or another application framework. The README does a good job explaining the two modes, especially the practical difference between Register GHM and Hook GHM, and I appreciated that it calls out important operational details like administrator privileges, worker-thread callbacks, Wayland limitations, and Windows low-level hook timing. Those caveats are exactly the kind of information developers need before embedding hotkey behavior into a production app.

The project structure also looks approachable: CMake-based build files, public headers under include/global_hotkey, implementation under src, and separate example and doc folders. The simple and event-queue examples are a good starting point, and the build options make the library feel configurable rather than a one-off demo.

The biggest adoption gap is trust and verification. The repo currently has only one commit, no releases, no packages, no visible CI, and no obvious test suite, which makes it harder for users to know whether Windows, macOS, X11, and Wayland behavior is continuously checked. I’d prioritize adding GitHub Actions builds across at least Windows, macOS, and Ubuntu, plus a small documented test or smoke-test strategy for register vs hook modes. A versioned release with install instructions for CMake consumers would also make the library much easier to depend on. Finally, the README is useful but could benefit from polished English and a clearer API reference for ownership, thread safety, invalid hotkey behavior, and cleanup expectations.
