A Completely Visual Language for Object-oriented Programming

Writing large and complex programs is a difficult, error-prone task. In this project, we have designed and implemented a visual programming language and graphical programming environment that is intended to make programming easier. In particular, our language, VIPR, is based on graphical program transformation semantics. With the VIPR design and implementation, we have explored a number of significant issues, including the formal specification of visual languages, the representation of expressions using graphical transformations, and language environment support for large visual programs. We currently have a working VIPR implementation, and are planning to make this implementation publicly available in the near future
