Hierarchical layer-based class extensions in Squeak/Smalltalk
Pages 107 - 112
Abstract
Class extensions are frequently used in programming languages such as Ruby and Smalltalk to add or change methods of a class that is defined in the same application or in a different one. They suffer from modularity issues if globally visible: Other applications using the same classes are then affected by the modifications. This paper presents a hierarchical approach for dynamically scoping class extensions in dynamically-typed, class-based programming languages supporting class nesting. Our mechanism allows programmers to define the scope of class extensions and to reuse class extensions in other programs. Class extensions can be scoped according to a nested class hierarchy or based on whether programmers regard a potentially affected class as a black box or not. Class extensions are organized in layers, where multiple layers targeting the same class can be active at the same time.

Matriona: class nesting with parameterization in Squeak/Smalltalk
MODULARITY 2016: Proceedings of the 15th International Conference on ModularityWe present Matriona, a module system for Squeak, a Smalltalk dialect. It supports class nesting and parameterization and is based on a hierarchical name lookup mechanism. Matriona solves a range of modularity issues in Squeak. Instead of a flat class ...
Classboxes: controlling visibility of class extensions
A class extension is a method that is defined in a module, but whose class is defined elsewhere. Class extensions offer a convenient way to incrementally modify existing classes when subclassing is inappropriate. Unfortunately existing approaches suffer ...
Method shelters: avoiding conflicts among class extensions caused by local rebinding
AOSD '12: Proceedings of the 11th annual international conference on Aspect-oriented Software DevelopmentA class extension, also known as open classes, allows programmers to modify existing classes and thus it is supported by several programming languages. However, class extensions imply a risk that they supply different definitions for the same method and ...
