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

  1. id : string;

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.
