Module Frama_c_kernel.Typed_parameter

Parameter settable through a command line option. This is a low level API, internally used by the kernel. As a plug-in developer, you certainly prefer to use the API of Plugin instead.

type ('a, 'b) gen_accessor = {
get : unit -> 'a;
set : 'a -> unit;
add_set_hook : ( 'b -> 'b -> unit ) -> unit;
add_update_hook : ( 'b -> 'b -> unit ) -> unit;
}

generic accessor type

type 'a accessor = ( 'a, 'a ) gen_accessor
type typed_accessor =
| Bool of bool accessor * string option(*

the negative option, if any

*)
| Int of int accessor * unit -> int * int(*

getting range

*)
| String of string accessor * unit -> string list(*

possible values

*)
type parameter = private {
name : string;(*

Name of the option corresponding to the parameter. It is exactly the state name of the option (see State.get_name).

*)
help : string;(*

Help message

*)
accessor : typed_accessor;(*

How to get and set the value of the parameter

*)
visible : bool;(*

Is visible to the user, e.g. in the command-line help

*)
reconfigurable : bool;(*

Can be reconfigured, e.g. in the GUI

*)
is_set : unit -> bool;(*

Is this option really set?

val ty : t Type.t
val name : string

Unique name of the datatype.

val descr : t Descr.t

Datatype descriptor.

val packed_descr : Structural_descr.pack

Packed version of the descriptor.

val reprs : t list

List of representants of the descriptor.

val equal : t -> t -> bool

Equality: same spec than Stdlib.(=).

val compare : t -> t -> int

Comparison: same spec than Stdlib.compare.

Hash function: same spec than Hashtbl.hash.

val pretty : Stdlib.Format.formatter -> t -> unit

Pretty print each value in an user-friendly way.

val mem_project : ( Project_skeleton.t -> bool ) -> t -> bool

mem_project f x must return true iff there is a value p of type Project.t in x such that f p returns true.

val copy : t -> t

Deep copy: no possible sharing between x and copy x.

val get : string -> t

Get the parameter from the option name.

val get_value : t -> string
