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.
