val parse_options : bool -> string -> unit

val parse_alert_option : string -> unit

Disable/enable alerts based on the parameter to the -alert command-line option. Raises Arg.Bad if the string is not a valid specification.

val without_warnings : (unit -> 'a) -> 'a

Run the thunk with all warnings and alerts disabled.

val is_active : t -> bool

val is_error : t -> bool

val defaults_w : string

val defaults_warn_error : string

type reporting_information = {

id : string;
message : string;
is_error : bool;
sub_locs : (loc * string) list;

}

val report : t -> [ `Active of reporting_information | `Inactive ]

val report_alert : alert -> [ `Active of reporting_information | `Inactive ]

exception Errors

val check_fatal : unit -> unit

val reset_fatal : unit -> unit

val help_warnings : unit -> unit

type state

val backup : unit -> state

val restore : state -> unit

val mk_lazy : (unit -> 'a) -> 'a Lazy.t

Like Lazy.of_fun, but the function is applied with the warning/alert settings at the time mk_lazy is called.
