Introduction

Stratego Regular is a package of tools for working with tree languages. A tree language is a set of trees define by a tree grammar. Stratego Regular defines the concrete and abstract syntax of RTG, a language for regular tree grammars, and RHG, a language for regular hedge grammars^?. The RTG and RHG languages are used to define tree languages.

Tools

• sdf2rtg^? -- generates an abstract syntax definition in RTG from an SDF syntax definition.
• rtg2sig -- generates a Stratego signature from an abstract syntax definition in RTG.
• format-check^? -- Check if an ATerm is part of the language defined by an RTG.
• rtg2typematch -- Generates a duck-typing based strategy that checks if an ATerm is of a type defined in an RTG.
