Re: Parse an EBNF grammar with instaparse?

You may also be able to write an instaparse grammar for EBNF (a grammar of grammars)—Loner contains a parser-combinator-style EBNF parser, so it's certainly do-able. Then you could use that parser to parse your grammar—presumably the parsers yield trees on input-strings. D. Ben Knoble O

Re: Parse an EBNF grammar with instaparse?

I haven't touched Clojure in a year or two, and I'm not familiar with instaparse. I can say, from a terminology stand-point, that a grammar (such as one in EBNF) can produce a parser, which then produces parse-trees of input strings. So, perhaps you mean that you want parse-trees of strings in
