Generation of S-expression conversion functions from type definitions
Browse cluster: OCaml incremental computation and PPX tooling →ppx_sexp_conv is a PPX syntax extension for OCaml that automatically generates code to convert between OCaml types and s-expressions (a data format defined by the sexplib library). The project fits into the ppx_deriving framework, allowing developers to annotate type definitions with `[@@deriving sexp]` to automatically create serialization and deserialization functions. Beyond basic conversions, ppx_sexp_conv supports advanced features including sexp grammar generation, optional record fields, default values, polymorphic variants, exceptions, and memory-optimized stack-allocation modes. The tool covers a comprehensive range of OCaml types—from primitives and collections to records, variants, polymorphic values, and even hash tables—each with specific serialization rules.
