A Formal Reference for SCOOP

Free registration required

Executive Summary

Operational semantics is a flexible but rigorous means to describe the meaning of programming languages. Small semantics are often preferred, for example to facilitate model checking. However, omitting too many details in a semantics limits results to a core language only, leaving a wide gap towards real implementations. In this paper, the authors present a comprehensive semantics of the concurrent programming model SCOOP (Simple Concurrent Object-Oriented Programming). The semantics has been found detailed enough to guide an implementation of the SCOOP compiler and runtime system, and to detect and correct a variety of errors and ambiguities in the original informal specification and prototype implementation.
