val lident : string -> Longident.t
val gen_symbol : ?prefix:string -> unit -> string

gen_symbol ?prefix () generates a fresh variable name with prefix.

  • parameter prefix

    default = "_x"

val string_of_core_type : Astlib.Ast_412.Parsetree.core_type -> string
val assert_no_attributes : Astlib.Ast_412.Parsetree.attribute list -> unit
val assert_no_attributes_in : Ast_traverse.iter

get_tparam_id tp returns the string identifier associated with tp if it is a type parameter.

(new type_is_recursive rec_flag tds)#go () returns whether rec_flag, tds is really a recursive type. We disregard recursive occurrences appearing in arrow types. You can override the search for certain type expressions by inheriting from this class.

really_recursive rec_flag tds = (new type_is_recursive rec_flag tds)#go ()

convert multi-arg function applications into a cascade of 1-arg applications

val attribute_of_warning : Location.t -> string -> Astlib.Ast_412.Parsetree.attribute

Encode a warning message into an 'ocaml.ppwarning' attribute which can be inserted in a generated Parsetree. The compiler will be responsible for reporting the warning.

val is_polymorphic_variant : Astlib.Ast_412.Parsetree.type_declaration -> sig_:bool -> [> `Definitely | `Maybe | `Surely_not ]
val mk_named_sig : loc:Location.t -> sg_name:string -> handle_polymorphic_variant:bool -> Astlib.Ast_412.Parsetree.type_declaration list -> Astlib.Ast_412.Parsetree.module_type Astlib.Ast_412.Parsetree.include_infos option

mk_named_sig ~loc ~sg_name:"Foo" ~handle_polymorphic_variant tds will generate

include Foo (* or Foo1, Foo2, Foo3 *)
  with type (* ('a, 'b, 'c) *) t := (* ('a, 'b, 'c) *) t

when:

  • there is only one type declaration
  • the type is named t
  • there are less than 4 type parameters
  • there are no constraints on the type parameters

It will take care of giving fresh names to unnamed type parameters.
