Visual programming with graph rewriting systems
Andy Schürr, Andreas J. Winter, Albert Zündorf · 2002
The multi-paradigm language PROGRES is the first rule-oriented visual language which has a well-defined type concept and supports programming with graph rewriting systems. To some extent, it has the flavor of a visual database programming language with powerful pattern matching and replacing facilities as well as backtracking capabilities. Until now, it was mainly used for specifying and rapid prototyping of abstract data types in software engineering environments. An integrated set of language-specific tools supports intertwined editing, analyzing, browsing, and debugging of specifications as well as generating prototypes in C (Modula-2) with Tcl/Tk-based user interfaces.
