META II

This is not really such a new concept. It is a different syntax, basically the identical concepts we see in META II(1964), TREEMETA(1968) and CWIC(1970). Not novel or new. Then again Parsing Expression Grammar is not a new or different concept. These grammars are expressing the syntax analysis using order dependent rules. The opposite of languages like BNF (Backus–Naur Form). Designing a parser from a generative language like BNF is a difficult endeavor. It is great that we have Parsing Expression Grammar recognized as a type of grammar defining language.

All these compiler related subjects need to be edited for consistency. — Preceding unsigned comment added by Steamerandy (talk • contribs) 18:49, 4 October 2014 (UTC)[reply]
