Formal Languages And Compilation

This fully revised and expanded new edition elucidates the elegance and simplicity of the fundamental theory underlying Formal Languages and Compilation. Retaining the reader-friendly, minimalist style of the first edition, this uniquely versatile textbook describes the essential principles and methods used for defining the syntax of artificial languages, and for designing efficient parsing algorithms and syntax-directed translators with semantic attributes. A comprehensive selection of topics is presented within a rigorous, unified framework, illustrated by numerous practical examples. Features and topics: Presents a novel conceptual approach to parsing algorithms that applies to extended BNF grammars, together with a parallel parsing algorithm (NEW) Supplies supplementary teaching tools, including course slides and exercises with solutions, at an associated website Unifies the concepts and notations used in different approaches, enabling an extended coverage of methods with a reduced number of definitions Systematically discusses ambiguous forms, allowing readers to avoid pitfalls when designing grammars Describes all algorithms in pseudocode, so that detailed knowledge of a spec
