Towards a Visual Programming Environment Generator for Algebraic Specifications

In the visual languages community there has been a growing consensus that visual languages will be most successful in the case of special purpose languages. Furthermore, their success will largely depend on the programming environment which is provided for them. Programming environment generators, generate programming environments for formally speciied languages. This paper discusses speciication of visual languages and the generation of visual environments. We focus on a picture deenition language, Vodl, which serves as the basis for deening the syntax of visual languages. We present the language deenition and an example showing how Vodl is used in deening language syntax and thereafter generating visual editors. Finally, we discuss how to extend this approach in creating a visual speciication formalism and a supporting environment for specifying the syntax and semantics of visual languages.
