Instaparse is an easy-to-use, feature-rich parser generator for Clojure.
The two stand-out features:
1. Converts standard EBNF notation for context-free grammars into an
executable parser. Makes the task of building parsers as lightweight and
simple as working with regular expressions.
2. Works with *any* context-free grammar. This means you don't have to
learn the esoteric subtleties of LR, LL, LALR or any other specialized
subset. Left-recursion, right-recursion, ambiguous grammars -- instaparse
handles it all.
Example:
(def as-and-bs
(parser
"S = AB*
AB = A B
A = 'a'+
B = 'b'+"))
=> (as-and-bs "aaaaabbbaaaabb")
[:S
[:AB [:A "a" "a" "a" "a" "a"] [:B "b" "b" "b"]]
[:AB [:A "a" "a" "a" "a"] [:B "b" "b"]]]
