The theory of parsing is an important application area of the theory of formal languages and automata. The evolution of modem high-level programming languages created a need for a general and theoretically dean methodology for writing compilers for these languages. It was perceived that the compilation process had to be "syntax-directed", that is, the functioning of a programming language compiler had to be defined completely by the underlying formal syntax of the language. A program text to be compiled is "parsed" according to the syntax of the language, and the object code for the program is generated according to the semantics attached to the parsed syntactic entities. Context-free grammars were soon found to be the most convenient formalism for describing the syntax of programming languages, and accordingly methods for parsing context-free languages were devel oped. Practical considerations led to the definition of various kinds of restricted context-free grammars that are parsable by means of efficient deterministic linear-time algorithms.

Hardcover. Condizione: new. Hardcover. The entire work Parsing Theory appears in two volumes, "Volume I: Languages and Parsing" and "Volume II: LR(k) and LL(k) Parsing". The two volumes form an integral work. Volume I is an introduction to the basic concepts of languages and parsing, and it also contains the relevant mathematical and computer scientific background needed in the development of the theory of deterministic parsing; it deals with topics such as algorithms on relations and graphs, regular languages and lexical analysis, context-free languages, left parsers and right parsers, strong LL(k) parsers and their implementation, simple precedence parsers. Volume II contains a thorough treatment of the theory of LR(k) and LL(k) parsing. "Parsing Theory" is a contemporary reference work on the theory of deterministic parsing of context-free languages. It emphasizes the LR(k) and LL(k) methods, which are developed in a uniform manner and pays special attention to their efficient implementation. Construction algorithms for parsers are derived from general graph-theoretic methods. Complexity questions about parsable grammars are analyzed.The work can be used as a textbook for graduate-level and senior undergraduate-level courses on parsing theory and compiler design. A one-semester course on the basic theory of languages and parsing can be taught from Volume I. The theory of parsing is an important application area of the theory of formal languages and automata. Context-free grammars were soon found to be the most convenient formalism for describing the syntax of programming languages, and accordingly methods for parsing context-free languages were devel oped.
