A language implementation framework in Java

Abstract

An object-oriented language implementation environment called TaLE is presented. TaLE consists of an OO framework that provides basic language implementation mechanisms, and of a graphical editor that supports visual syntactic specifications and various kinds of language-oriented specializations, generating the desired subclasses for the framework. Parsing is based on a model in which parsing information is distributed at runtime among the metaobjects representing language structures. The TaLE approach facilitates the reuse of both syntactic and semantic classes.
