Visual language semantics specification in the VisPro system
Ke-Bing Zhang, Mehmet Ali Orgun, Kang Zhang · 2003
VisPro is a general-purpose visual language generation system, which can produce a wide range of diagrammatic visual programming languages (VPLs) based on Reserved Graph Grammar (RGG), a context sensitive graph grammar. This paper presents an approach to specify the semantic execution sequence of VPLs based on VisPro. In this approach, we use an ordering mechanism to facilitate the parsing formalism of Reserved Graph Grammar to determine semantic execution sequence of super-nodes in visual programs of the VPLs.
