  a parser and lexer generator as a Rust procedural macro (by goffrie)

Hi! Im currently developing a compiler in Rust. I am looking for a good parser and lexer generator. I was looking at plex (https://github.com/goffrie/plex), but it is pretty new and I'm not sure if it is stable and useful, or if there are better alternatives. I found a similar post here: https://www.reddit.com/r/rust/comments/e0fj6f/best_rust_parser_and_lexer_generators/?utm_source=share&utm_medium=web2x&context=3

• re2c

  12 1,026 6.8 C

  Lexer generator for C, C++, Go and Rust.

Those suggested crates are still more or less the popular options. There was also recently added support for Rust in re2c.

antlr4 is a really great modern parser/lexer generator framework. It's language-agnostic, but IIRC the Rust bindings aren't the greatest but it's usable. It's a lot more performant than the random stuff you will find on crates.io . It has support for left recursion and setting associativity and precedence is really easy.
