Package: wnpp Version: unavailable; reported 2003-07-16 Severity: wishlist * Package name : yapps2 Version : 2.0.3 Upstream Author : Amit Patel <[EMAIL PROTECTED]> * URL : http://theory.stanford.edu/~amitp/Yapps/ * License : BSD Description : A Recursive Descent Parser Generator for Python
[ Note: I intend to edit this description prior to uploading the package. The text below comes largely from the Yapps website. Please refrain from flamage at this stage. ] Yapps (Yet Another Python Parser System) is an easy to use parser generator that is written in Python and generates Python code. Although there are several parser generators already available for Python (most of them lex/yacc clones), the Yapps project has different goals. Yapps is designed to be used when regular expressions are not enough and other parser systems are too much: situations where you may write your own recursive descent parser. . Some unusual features of Yapps that may be of interest are: . 1. Yapps produces human-readable recursive descent parsers. There are several heuristics used to keep the generated code simple. . 2. Yapps produces context-sensitive scanners that pick tokens based on the type of tokens accepted by the parser. In some situations, token matching is ambiguous unless the context is taken into account. . 3. Yapps rules can pass arguments down to subrules, so subrules can use information (such as declarations) that was parsed at higher levels in the parsing process. These are sometimes called attribute grammars. . This package is named yapps2 because it is incompatible with Yapps 1. Yapps 2.0 introduced new-style Python regular expressions, much tighter embedded code and iterative parsing, optional matching, etc. -- System Information: Debian Release: testing/unstable Architecture: i386 Kernel: Linux wile 2.4.20 #2 Mon Jun 9 14:29:13 CDT 2003 i686 Locale: LANG=C, LC_CTYPE=en_US
