Welcome to the 4th International Workshop on Context-Oriented Programming, co-located with the 26th European Conference on Object-Oriented Programming.
Context information plays an increasingly important role in our information-centric world. Software systems must adapt to changing contexts over time, and must change even while they are running. Unfortunately, mainstream programming languages and development environments do not support this kind of dynamic change very well, leading developers to implement complex designs to anticipate various dimensions of variability. Starting from this observation, Context-Oriented Programming (COP) has emerged as a solution to directly support variability depending on a wide range of dynamic attributes, making it possible to dispatch run-time behaviour on any property of the execution context.
The goal of the 4th International Workshop on Context-Oriented Programming (COP’12) is to further establish context orientation as a common thread to language design, application development, and system support. Several researchers are working on Context-Oriented Programming and related ideas, and implementations ranging from prototypes to mature platform extensions used in commercial deployments have illustrated how multi-dimensional dispatch can indeed be supported effectively to achieve expressive run-time behavioural variations.
