Module Ast.TypSource

Types

This modules allows extending Mopsa with new types. This is done by extending the type typ with new variants. For example

  type typ += T_int

extends Mopsa types with a new integer type. Registration is performed with

  let () = register_typ {
      compare = (fun next -> next);
      print = (fun next -> function
          | T_int -> Format.pp_print_string fmt "int"
          | t    -> next fmt t
        );
    }

Note that is this simple example where the type doesn't have an inner structure no comparison function is required as Stdlib.compare is sufficient to provide a total order.
