Lesson plan
Emerald (programming language)
Emerald is a distributed, object-oriented programming language developed in the 1980s by Andrew P. Black, Norman C. Hutchinson, Eric B. Jul, and Henry M. Levy, in the Department of Computer Science at the University of Washington. A simple Emerald program can create an object and move it around the system: const Kilroy ← object Kilroy process const origin ← locate self const up ← origin.getActiveNodes for e in up const there ← e.getTheNode move self to there end for move self to origin end process end Kilroy Emerald was designed to support high performance distribution, location, and high performance of objects, to simplify distributed programming, to exploit information hiding, and to be a small language.
