Grammar reuse
My latest blog post looks at a grammar reuse, comparing regular expressions, PEG, Perl 6 grammars and general BNF parsers, including Marpa. A good property to have in itself, grammar reusability is crucial if a parser is going to be the basis for language-driven programming.
I blog about Perl, with a focus on parsing and Marpa, my parsing algorithm based on Jay Earley's.
