Generador de Compiladores Coco/R

Hanspeter Mössenböck, Universidad Johannes Kepler en Linz

Coco/R toma una descripción de un compilador en la forma de una gramática atribuida (sintaxis EBNF con acciones de atributos y semántica) y la traduce en un scanner y un analizador de descenso recursivo. El usuario debe añadir módulos para el manejo de tablas de símbolos, optimización y generación de códigos para ejecutar un compilador. Los conflictos LL (1) pueden ser solucionados por un mecanismo especial de pre análisis. Coco/R ha sido usado con éxito en academias e industrias. Combina la funcionalidad de Lex y Yacc, las reconocidas herramientas de Unix.

Coco/R está disponible bajo GNU GPL desde http://ssw.jku.at/coco/

Aquí está un ejemplo de una pequeña descripción de un compilador con Coco/R:
