S expressions are one of the most used serialization formats in OCaml. You can get pretty far relying on the standard parsers and printers. It's what I would do for a lisp in OCaml. Maybe you wanted to DIY as a learning thing? There are other options for parsing including parser combinators or using Menhir/ocamllex which are interesting in their own right. https://dev.realworldocaml.org/data-serialization.html https://dev.realworldocaml.org/data-serialization.html https://dev.realworldocaml.org/parsing-with-ocamllex-and-menhir.html https://dev.realworldocaml.org/parsing-with-ocamllex-and-men...
