  7. …tree-sitter grammars couldn't be written in an internal DSL, perhaps in parser-combinator style ( https://github.com/engelberg/instaparse does this). That could smooth over a lot of the rough edges.

  20. Instaparse in Clojure ( https://github.com/Engelberg/instaparse ) seems similar (although I don't know Rebol/Red so I'm purely guessing from looking at parse examples). You can get close-ish results with parser combinator libraries as well.
    comment by dwohnitmok · 2017-12-27 · in Ask HN: Rebol/Red parse is great. Has it been re-implemented in other languages?

  24. …that don't pass the complexity on to the user. The parser library that has done this for me is https://github.com/engelberg/instaparse . Using Instaparse is downright liberating. BNF in, parser out. Done.
