Parse::RecDescent version 1.967002 NAME Parse::RecDescent - generate recursive-descent parsers DESCRIPTION RecDescent incrementally generates top-down recursive-descent text parsers from simple yacc-like grammar specifications. It provides: * Regular expressions or literal strings as terminals (tokens), * Multiple (non-contiguous) productions for any rule, * Repeated, optional and alternate subrules within productions, * Late-bound (run-time dispatched) subrules * Full access to Perl within actions specified as part of the grammar, * Simple automated error reporting during parser generation and parsing, * The ability to commit to, uncommit to, or reject particular productions during a parse, * Incremental extension of the parsing grammar (even during a parse), * Precompilation of parser objects, * User-definable reduce-reduce conflict resolution via "scoring" of matching productions. LIMITATIONS * There's no support for parsing directly from an input stream. * The generator doesn't handle left-recursion. PREREQUISITES Parse::RecDescent requires the Text::Balanced module, which is available from the CPAN. INSTALLATION It's all pure Perl, so just put the .pm files in their appropriate local Perl subdirectories. CHANGES AND FUTURE DEVELOPMENT This readme refers to versions 1.XXXXXX. For details of changes, refer to the file Changes. Version 2.00 will provide a cleaner interface and better parsing performance. AUTHOR Damian Conway (email@example.com) Jeremy T.
