It says it is the logical negation of a "rule" but then goes on to say that it negates the "characters". What does -"ab" mean? If you're just negating characters, in instaparse you can just use regex's capability to express negative character classes. So, for example, "every character but an a" is most clearly and efficiently expressed as #"[^a]". http://www.regular-expressions.info/charclass.html -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
