A Clojure library designed to generate parsers from bnf grammars.
I don't know a lot about parsers, so the generated parsers are most likely not any good.
The generated parsers take seqs as inputs.
The generated parsers are not perfect, certain formulations of grammars can cause the parsers to blow the stack, etc.
bnfu is bootstrapped, I hand wrote a parser for bnfs, fed it a bnf of bnf, an generated a new parser from that parse tree.
[org.thelastcitadel/bnfu 0.0.1] in your project.clj
(bnf "foo/bar.bnf")where foo/bar.bnf is a bnf as a file on the classpath well generate functions for the parser (bnf is a macro), with a main entry point named after the first rule in the grammar like parse-{rule-name}.
the parse tree is hiccup style.
see org.thelastcitadel.bnfu.prolog and
org.thelastcitadel.bnfu.stomp for examples.
if you reference a rule, but leave out a definition you can hand write the function for that rule.
