sys_appearance is a small mac OS utility that makes it easy for third party applications to get real time notifications of mac OS system appearance, as well as the current appearance.
This tool is meant to replace the rust implementation in dark-notify, because it uses nightly APIs which were unstable and no longer exist in recent versions of rust.
makesys_appearance can handle multiple clients at once, so it is advised to keep one instance running
in the background (preferably using launchd and at launch.) For application instances that wish
to start a instance at will per session, the port will be echoed to standard out. This port is selected by
the kernel.
You can test the tool by running nc localhost <port>. Along with seeing the current system
appearance, updates will also be sent through the socket.
sys_appearance will also advertise itself through Bonjour under _sys_appearance._tcp.
