Context-oriented Programming, or COP, provides programmers with dedicated abstractions and mechanisms to concisely represent behavioral variations that depend on execution context. By treating context explicitly, and by directly supporting dynamic composition, COP allows programmers to better express software entities that adapt their behavior late-bound at run-time. Our paper illustrates COP constructs, their application, and their implementation by developing a sample scenario, using Contexts in the Squeak/Smalltalk programming environment.
