I’m aware of [ppxlib/examples at main · ocaml-ppx/ppxlib · GitHub](https://github.com/ocaml-ppx/ppxlib/tree/main/examples) but I’m looking for something with more than 2 examples.

My favorite resource for learning Rust was [Introduction - Rust By Example](https://doc.rust-lang.org/rust-by-example/) where instead of reading the manual, one types in \< 500 line examples for each language feature.

I am wondering if there is a similar resource for ppxlib, where instead of trying to digest the manual upfront, the resource provides lots of \< 500 line example showcasing features of ppxlib.

I don’t know of something as comprehensive as what you would like. However I would recommend reading (and re-reading) [this tutorial](https://ocaml-explore.netlify.app/workflows/meta-programming-with-ppx/) by @patricoferris . I’ve found it the most approachable and comprehensible introduction to the PPX ecosystem. If you read the official documentation afterwards have Patricks guide off to the side to refer back to.
