FEDELE: A Mechanism for Exending the Syntax and Semantics for the Hybrid Functional-Object-Oriented Scripting Language FOBS

A language FOBS-X (Extensible FOBS) is described. This language is an interpreted language, intended as a universal scripting language. An interesting feature of the language is its ability to be extended, allowing it to be adapted to new scripting environments. The interpretation process is structured as a core-language parser back-end, and a macro processor front-end. The macro processor allows the language syntax to be modified. A configurable library is used to help modify the semantics of the language, allowing the addition of the required capabilities for interacting in a new scripting environment. This paper focuses on the semantic extension of the language. A tool called FEDELE has been developed, allowing the user to add library modules to the FOBS-X library. In this way the semantics of the language can be enhanced, and the language can be adapted to new scripting environments.
