DeltaJ: a delta oriented programming language with core and delta modules

DeltaJ is a Java-like language supporting software product lines development, as illustrated in the paper: Ina Schaefer, Lorenzo Bettini, Viviana Bono, Ferruccio Damiani, Nico Tanzarella: Delta-Oriented Programming of Software Product Lines. SPLC 2010: 77-91, LNCS 6287, Springer, 2010 (product number 503765 of the "Catalogo di Ateneo"). It allows to build software in modules and modify an existing class within a module keeping the old one, in order to allow the software maintenance and reuse. There are two kind of modules: core and delta. A core module is a simple collection of classes, while a delta module is a set of operations that allow to add a new class and modify or remove classes declared in other delta or core modules. The software is so organized in a single core module and a set of delta modules dependents on each other or on the core module. We provide a stand-alone compiler as well as an Eclipse text editor, with standard IDE functionalities (syntax highlighting, code completion, outline, building, etc.). All software is GPL.
