Port Terminal to LibGUI. To facilitate listening for action on arbitrary file descriptors, I've added a GNotifier class. It's quite simple but very useful: GNotifier notifier(fd, GNotifier::Read); notifier.on_ready_to_read = [this] (GNotifier& fd) { // read from fd or whatever else you like :^) }; The callback will get invoked by GEventLoop when select() says we have something to read on the fd.

CNotifier: Turn into a CObject and Use the event queue to deliver events This way, CNotifier can mutate state to its little heart's content without destroying the world when the global CNotifier hash changes during delivery.

LibCore: Introduce a C_OBJECT macro. This macro goes at the top of every CObject-derived class like so: class SomeClass : public CObject { C_OBJECT(SomeClass) public: ... At the moment, all it does is create an override for the class_name() getter but in the future this will be used to automatically insert member functions into these classes.
