Parameter X : Ocaml_dynloader.Module_type


type t

The type t is the type of a first level module you want to load. This is typically the type of your expected config file, as a top level ocaml module.

The field repr is the concrete OCaml syntax for this module type.

The field univ_constr is used to constr and match_ values of type t, embedded in a value of type Univ.t.

The field univ_constr_repr is the concrete OCaml syntax for the field univ_constr.

Example : TODO: CUSTOM defined in the library "mylib.cmxa".

     module My_config_loader = Ocaml_plugin.Ocaml_dynloader.Make (
       type t = (module A.S)
       let repr = "Mylib.A.S"
       let univ_constr = A.univ_constr
       let univ_constr_repr = "Mylib.A.univ_constr"

repr and univ_constr_repr should be contain complete paths, as it would be used by an ocaml file to link with the shared cmi files, in particular be aware that if you have some 'open' statements in your file, you might have different t and repr, which is a bad practice.

If the module type A.M_intf is defined in a package, you would need to add it in the repr, as it is part of the complete path of the module type ("Mylib" in the example).
