| libparse-recdescent-perl | generates recursive-descent parsers in Perl | Mehr ... |
The Perl module Parse::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 sub-rules within productions,
* Late-bound (run-time dispatched) sub-rules
* 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),
* The ability to retrieve the generated parsing code. |
