Thanks everyone who has participated in the poll! ❤ It seems like a few people do appreciate the monthly posts, so I/we’ll keep on doing them. If anyone has any comment, just let us know. However, according to the current state of the poll, there’s also one person who finds this thread a bit spammy - and there might be more. I’ll leave the poll open for as long as discuss allows me, so that I can see if that number increases in the future. In the meantime: I’m sorry for the inconvenience for the very few who find the posts spammy!

This month, we’re having the meeting on Monday instead of Tuesday, same time as always: 2024-02-19T17:00:00Z . That’s also reflected in the public calendar event. Here’s our agenda. Remember that everyone is welcome to add things:

- 5.2 support
  - Let’s discuss the complicated compiler AST changes for 5.2, among others, if we’re testing their support enough.
    - Syntactic support for functions with arity \> 1
    - Have there been more complicated AST changes this time?

  - The compiler `ocaml.ppx.context` change
    - This affects the PPX world iff people want to build their project with a different OCaml version than their PPX is built with. Do we want to keep on supporting that workflow?
    - Why was the change of `ocaml.ppx.context` in the compiler done in a breaking way? Is it worth for us to discuss that with them?

  - The ppxlib `~preview` release with 5.2 support

- Upcoming things to do on `ppxlib`
  - When to start with the work to bump ppxlib’s AST to 5.2?
  - When to start with the upstream `Astlib` efforts?

- In case we have time, let’s also discuss how to improve the repo for people to get involved easier (issue labels, contribution guidelines etc)

Update: Here are the notes: [Dev meeting 19 02 2024 · ocaml-ppx/ppxlib Wiki · GitHub](https://github.com/ocaml-ppx/ppxlib/wiki/Dev-meeting-19-02-2024) . Apart from @NathanReb, @panglesd and me, also @Octachron and @shonfeder have joined spontaneously 🙏 Thanks, both! The insight into compiler-related details, as well as the nice nudge towards the ppx\_deriving plug-ins, have been very helpful and nice.
