Parse STRING as an ABNF grammar as defined in RFC 2234. Returns a cl-ppcre
scanner that will only match strings conforming to given grammar.
See http://tools.ietf.org/html/rfc2234 for details about the ABNF specs. Added to that grammar is support for regular expression, that are expected in the ELEMENT production and spelled ~/regex/. The allowed delimiters are: ~// ~[] ~{} ~() ~<> ~"" ~” ~|| and ~##.
An alist of the usual rules needed for ABNF grammars
See http://tools.ietf.org/html/rfc2234#section-4
Given a rule, expand it completely removing references to other parsed rules
Expand given rule DEFINITION within given RULE-SET
Helper function to process different kinds of quotes for regexps
Turn the string we read in the ABNF into internal symbol.
This serves as a test and an example: if you’re going to use the same scanner more than one, be sure to compute it only once.
