Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We present a method for recovering from syntax errors encountered during parsing. The method provides a form of minimum distance repair, has linear time complexity, and is completely automatic. It is incorporated into the LR parser-generator yacc in such a way that the compiler writer can generate a parser with recovery without providing any additional information to yacc [sic] Error messages phrased in terms of source input are generated automatically. We present a formal method for evaluating the performance of error recovery methods, based on global minimum-distance error correction, and show that the error recovery method presented achieves a theoretically best performance on 80% of Pascal programs in the Ripley-Druseikis collection."

Available in PDF, EPUB and Kindle. Book excerpt: A 'forward move algorithm' and some of its formal properties are presented for use in a practical syntactic error recovery scheme for LR parsers. The algorithm finds a 'valid fragment' (comparable to a valid prefix) just to the right of a point of error detection. For expositional purposes the algorithm is presented as parsing arbitrarily far beyond the point of error detection in a 'parallel' mode, as long as all parses agree on the read or reduce action to be taken at each parse step. In practice the forward move is achieved serially by adding 'recovery states' to the LR machine. Based on the formal properties of the forward move we propose a practical error recovery algorithm that uses the 'right context' accumulated by the forward move. The performance of the recovery algorithm is illustrated in a specific case and discussed in general. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This work is Volume II of a two-volume monograph on the theory of deterministic parsing of context-free grammars. Volume I, "Languages and Parsing" (Chapters 1 to 5), was an introduction to the basic concepts of formal language theory and context-free parsing. Volume II (Chapters 6 to 10) contains a thorough treat ment of the theory of the two most important deterministic parsing methods: LR(k) and LL(k) parsing. Volume II is a continuation of Volume I; together these two volumes form an integrated work, with chapters, theorems, lemmas, etc. numbered consecutively. Volume II begins with Chapter 6 in which the classical con structions pertaining to LR(k) parsing are presented. These include the canonical LR(k) parser, and its reduced variants such as the LALR(k) parser and the SLR(k) parser. The grammarclasses for which these parsers are deterministic are called LR(k) grammars, LALR(k) grammars and SLR(k) grammars; properties of these grammars are also investigated in Chapter 6. A great deal of attention is paid to the rigorous development of the theory: detailed mathematical proofs are provided for most of the results presented.

This book was released on 2018-02-05 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Practical Method for Constructing Efficient Lalr(k) Parsers With Automatic Error Recovery: March 1991 One of the most important issues in LR parsing is to find suitable data structures for these parsing tables whose space requirement is. At worst. Proportional to the number of useful entries in the tables but whose time-efficiency is comparable to that of the matrix representation. Another important issue is that of providing an efficient error recovery svstem for this parsing framework. In particular, the lr) variants lose the inherent ability of their canonical counterpart to detect an error at the earliest possible point.

Download or read book Error Recovery for LR Parsers written by Thomas Julian Pennello and published by . This book was released on 1977 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical algorithm is described that allows an LR parser to parse past the point at which an error was detected. By thus parsing, context beyond the point of error detection is gathered. Several important properties about this forward context are proven its usefulness in the selection and evaluation of error repairs is demonstrated. At first specifically restricting the consideration to single occurrences of errors of insertion, deletion, or replacement of a single terminal symbol, the algorithm is given with suggested possible error repair strategies. Then a generalization to encompass recovery from any number and type of error is given.
