YooccLa: a parser generator for L-attributed grammars

Argues that a parser generator can be developed that: (1) can bring parser technology within the reach of more software engineers, (2) requires less knowledge of parser technology than most existing parser generators, and (3) can allow a parser to be used where a designer might otherwise have chosen a fully procedural solution. A parser generator, called YooccLa (Yes! An Object-Oriented Compiler Compiler with left-attributes), has been developed to achieve these goals. It reads a non-left-recursive LL grammar specified in an EBNF-like language, augmented with Eiffel features specifying semantic actions. For each grammar production, YooccLa produces a pair of classes for the Eiffel Parse library: a syntax class specifying the syntax to Eiffel Parse, and a construct class specifying the semantics
