URLs automatically rewritten from /search?dist=Foo or /dist/Foo to /dist/Foo/ (note trailing slash). After a 2002(!) reorganization, this is the preferred way to refer to modules on search.cpan.org. This pass brought to you by http://people.freebsd.org/~fenner/fix-search

|
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 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.
