Re^2: Yacc is dead

If you need it then it is mostly the case of a widespread language that has already good parsers.

• There are Earley parsers in Perl 5 Parse::Earley and Marpa.
• There are no GLR parsers in Perl 5, though is one of the most commonly used nowadays (search for GLR and Perl in google)
• I believe - not really sure - that though there is no explicit Packrat-parsing module, Regexp::Grammars conforms to the Packrat approach
• As far as I am aware, there is only one CPAN module giving support to attribute grammars: Language::AttributeGrammar

These are the available choices for the main "Parsing Algorithms" that I know in Perl 5/CPAN. Anything else?

OK - I agree that writing a parser using these new techniques would be valuable, and you did apparently do a lot of background research and this is all good for the community etc. My note was only a nitpick - don't take it too personally. I only wanted to say that at my work the standard HTML parser (or YAML parser or XML parser or .INI parser) is enough for all I ever needed. Writing a GLR parser or something else would be a great contribution - but so could be solving numerous other problems. My point really is that condescending people for getting things done using whatever available is low and that is what I see in the quoted sentence.

Should we run to implement the derivative parsers described in the paper in Perl?

"we" here means myself and the people I work with; which, of course, can include anyone who may be interested.
