Showing opaque values using Sexp

[Zeta611]

Hi, I'm wondering if I can use ocamlearlybird to show opaque values using sexp.

I'm using ocamlearlybird in VSCode.

I made some custom modules implementing to_sexp : t -> Sexp.t so that I can inspect opaque values using s-expressions.
Is there a way to inspect them using my custom to_sexp?
By "opaque values", I mean:

Fully-automatic solution would be cool, but I would still be very happy if I can manually invoke this method for variables in scope at a breakpoint.
Is there currently a way to do this?

Thank you for creating and maintaining this amazing tool!

I recall it being mentioned somewhere that it could be possible to at least register and use Format printers for types like the toplevel does because this is also all in bytecode. However, I'm not familiar with that somewhat magic system and haven't looked into it. ocamldebug itself has that: https://v2.ocaml.org/manual/debugger.html#ss:debugger-printers.

A similar system might work for registering more structured type-based output as well, either from s-exps or JSON.

Thank you for providing the pointer to the relevant doc for ocamldebug.
