Hello everyone, I am working on extending an existing OCaml project that is no longer maintained. I need to add caching for some of the complex types in that project - specifically, I want to save instances on the hard drive and load them during runtime instead of generating them each time. For ex…

You can define your own parallel types using type equations and add in [@@deriving sexp] or whatever serializer/deserializer you like to use. Look at CompilerPrinters.ml for a [@@deriving show] example. The deriver is added to the “unmodifiable” OCaml compiler source code at https://github.com/ocam…

[image] Mher_Tolpin: I also considered ppx_deriving, but that would necessitate tagging the original source code, which is not an optimal solution for me. This limitation can be overcome by using ppx_import . From their README: type%import longident = Longident.t [@@deriving show] let () = …

For a given ocaml version, Marshal.to_string could be your friend.

See Export/import data in OCaml - #10 by yawaramin and other messages in that thread. My suggestion, Umarshal, would not require changes to the existing types.
