Add pest_derive optional dependency #446

Open kvark opened 4 years ago

Would be good to avoid depending on both pest and pest_derive, just for convenience. Just like Serde, pest with pest_derive feature could re-export the macros.

This is something I wanted since I started using pest. The problem is, that everything (derive, generator and meta) depends on pest. That's a problem, because if you start including pest_derive in pest you'll get a cyclic depency.

It would be nice if somebody could restructure the crates so they don't depend on pest anymore.

i'm seeing an error "unresolved extern crate, can't find crate for pest_derive can't find crate" in pest version 2.1.3 using the example in its documentation.

am i missing something? Screen Shot 2022-02-06 at 9 46 42 AM

@syddo super late, but, I got the same issue. It was fixed by specifying the Rust edition in Cargo.toml (edition = "2021" under [package])
