Modules available for parsing with perl

[integral]

For various reasons I've been thinking about parsing, with Perl, quite a bit recently. I'm curious about what more unusual modules and methods are available for parsing with Perl. So far I have on my List:

• Parse::RecDescent
• Parse::Yapp
• Parse::Earley
• Perl6::Rules
• py

What have I missed?

There is also Adam Kennedy's PPI, partly funded by The Perl Foundation.

perl-byacc, a version of Berkeley yacc that produces parsers in Perl.

Add to that list hand-coded parsers. With Perl regular expressions, it is very easy (relative to most other languages) to implement a top-down, recursive descent parser on your own.

There are of course a whole bunch dedicated to parsing particular things:
• HTML::Parser
• XML::Parser
• SQL::Parser
• ...
