Pa_type_conv: Preprocessing Module for Registering Type Conversions

Generator registration

val add_generator : ?is_exn:bool ->
       string -> (Camlp4.PreCast.Ast.ctyp -> Camlp4.PreCast.Ast.str_item) -> unit

add_generator ?is_exn name gen adds the code generator gen, which maps type or exception declarations to structure items, where is_exn specifies whether the declaration is an exception. Note that the original type/exception declarations get added automatically in any case.

is_exn : = false

val add_generator_with_arg : ?is_exn:bool ->
       string ->
       'a Camlp4.PreCast.Gram.Entry.t ->
       (Camlp4.PreCast.Ast.ctyp -> 'a option -> Camlp4.PreCast.Ast.str_item) -> unit

add_generator_with_arg ?is_exn name entry generator same as add_generator, but the generator may accept an argument, which is parsed with entry.

val rm_generator : ?is_exn:bool -> string -> unit

rm_generator ?is_exn name removes the code generator named name.

val add_sig_generator : ?is_exn:bool ->
       string -> (Camlp4.PreCast.Ast.ctyp -> Camlp4.PreCast.Ast.sig_item) -> unit

add_generator ?is_exn name gen adds the code generator gen, which maps type or exception declarations to signature items, where is_exn specifies whether the declaration is an exception. Note that the original type/exception declarations get added automatically in any case.

is_exn : = false

val add_sig_generator_with_arg : ?is_exn:bool ->
       string ->
       'a Camlp4.PreCast.Gram.Entry.t ->
       (Camlp4.PreCast.Ast.ctyp -> 'a option -> Camlp4.PreCast.Ast.sig_item) -> unit

add_sig_generator_with_arg ?is_exn name entry generator same as add_sig_generator, but the generator may accept an argument, which is parsed with entry.

val rm_sig_generator : ?is_exn:bool -> string -> unit

rm_sig_generator name removes the code signature generator named name.

val get_conv_path : unit -> string

get_conv_path ()
Returns the name to module containing a type as required for error messages.

Utility functions

val get_loc_err : Camlp4.PreCast.Ast.Loc.t -> string -> string

get_loc_err loc msg generates a compile-time error message.

val hash_variant : string -> int

hash_variant str
Returns the integer encoding a variant tag with name str.

General purpose code generation module
