Announce : PLY-3.0

by David Beazley

February 6, 2009 Announcing : PLY-3.0 (Python Lex-Yacc) http://www.dabeaz.com/ply I'm pleased to announce a significant new update to PLY---a 100% Python implementation of the common parsing tools lex and yacc. PLY-3.0 adds compatibility for Python 2.6 and 3.0, provides some new customization options, and cleans up a lot of internal implementation details. If you are new to PLY, here are a few highlights: - PLY is closely modeled after traditional lex/yacc. If you know how to use these or similar tools in other languages, you will find PLY to be comparable. - PLY provides very extensive error reporting and diagnostic information to assist in parser construction. The original implementation was developed for instructional purposes. As a result, the system tries to identify the most common types of errors made by novice users. - PLY provides full support for empty productions, error recovery, precedence rules, and ambiguous grammars. - Parsing is based on LR-parsing which is fast, memory efficient, better suited to large grammars, and which has a number of nice properties when dealing with syntax errors and other parsing problems. Currently, PLY can build its parsing tables using either SLR or LALR(1) algorithms. More information about PLY can be obtained on the PLY webpage at: http://www.dabeaz.com/ply PLY is freely available and is licensed under the terms of the Lesser GNU Public License (LGPL).
