Description

Ppx_type_directed_value is a ppx that does [@@deriving]-style generation of type-directed values based on user-provided modules. The user-provided modules tell ppx_type_directed_value how to compose type-directed values (for example, combine type-directed values of the fields of a record to form a type-directed value for the record itself).

This allows a wide variety of PPXs such as ppx_sexp_conv, ppx_compare, ppx_enumerate, etc. to be implemented with ppx_type_directed_value, but with some runtime cost.

This PPX currently supports deriving type-directed values for records, ordinary & polymorphic variants and tuples. It also supports custom user-defined attributes on record and variant fields.

Build status

Results of building ppx_type_directed_value with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
