Behavior of option "-warn-special-float"

include Parameter_sig.S with type t = string
include Parameter_sig.S_no_parameter with type t = string
type t = string

Type of the parameter (an int, a string, etc). It is concrete for each module implementing this signature.

val set : t -> unit

Set the option.

val add_set_hook : (t -> t -> unit) -> unit

Add a hook to be called after the function set is called. The first parameter of the hook is the old value of the parameter while the second one is the new value.

val add_update_hook : (t -> t -> unit) -> unit

Add a hook to be called when the value of the parameter changes (by calling set or indirectly by the project library. The first parameter of the hook is the old value of the parameter while the second one is the new value. Note that it is **not** specified if the hook is applied just before or just after the effective change.

  • since Nitrogen-20111001
val get : unit -> t

Option value (not necessarily set on the current command line).

val clear : unit -> unit

Set the option to its default value, that is the value if set was never called.

val is_default : unit -> bool

Is the option equal to its default value?

val get_default : unit -> t

Get the default value for the option.

  • since 24.0-Chromium
val option_name : string

Name of the option on the command-line

  • since Carbon-20110201
val print_help : Format.formatter -> unit

Print the help of the parameter in the given formatter as it would be printed on the command line by -<plugin>-help. For invisible parameters, the string corresponds to the one returned if it would be not invisible.

  • since Oxygen-20120901
include State_builder.S
val self : State.t

The kind of the registered state.

val name : string
val mark_as_computed : ?project:Project.t -> unit -> unit

Indicate that the registered state will not change again for the given project (default is current ()).

val is_computed : ?project:Project.t -> unit -> bool

Returns true iff the registered state will not change again for the given project (default is current ()).

Exportation of some inputs (easier use of State_builder.Register).

val add_hook_on_update : (Datatype.t -> unit) -> unit

Add an hook which is applied each time (just before) the project library changes the local value of the state.

  • since Nitrogen-20111001
val howto_marshal : (Datatype.t -> 'a) -> ('a -> Datatype.t) -> unit

howto_marshal marshal unmarshal registers a custom couple of functions (marshal, unmarshal) to be used for serialization. Default functions are identities. In particular, this function must be used if Datatype.t is not marshallable and do_not_save is not called.

  • since Boron-20100401
val equal : t -> t -> bool
val add_aliases : ?visible:bool -> ?deprecated:bool -> string list -> unit

Add some aliases for this option. That is other option names which have exactly the same semantics that the initial option. If visible is set to false, the aliases do not appear in help messages. If deprecated is set to true, the use of the aliases emits a warning.

  • before 22.0-Titanium

    no visible and deprecated arguments.

val parameter : Typed_parameter.t
  • since Nitrogen-20111001
val set_possible_values : string list -> unit

Set what are the acceptable values for this parameter. If the given list is empty, then all values are acceptable.

  • since Beryllium-20090901
val get_possible_values : unit -> string list

What are the acceptable values for this parameter. If the returned list is empty, then all values are acceptable.

  • since Beryllium-20090901
val get_function_name : unit -> string

returns the given argument only if it is a valid function name (see Parameter_customize.get_c_ified_functions for more information), and abort otherwise.

Requires that the AST has been computed. Default getter when Parameter_customize.argument_is_function_name has been called.

  • since Sodium-20150201
val get_plain_string : unit -> string

always return the argument, even if the argument is not a function name.
