type alert = Melange_wrapper.Warnings.alert = {

kind: string,
message: string,
def: loc,
use: loc,

};

let parse_options: bool => string => option(alert);

let 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.

let without_warnings: (unit => 'a) => 'a;

Run the thunk with all warnings and alerts disabled.

let is_active: t => bool;

let is_error: t => bool;

let defaults_w: string;

let defaults_warn_error: string;

type reporting_information = Melange_wrapper.Warnings.reporting_information = {

id: string,
message: string,
is_error: bool,
sub_locs: list((loc, string)),

};

let report: t => [ `Active(reporting_information) | `Inactive ];

let report_alert: alert => [ `Active(reporting_information) | `Inactive ];

exception Errors;

let check_fatal: unit => unit;

type state;

let backup: unit => state;

let restore: state => unit;

let with_state: state => (unit => 'a) => 'a;

let mk_lazy: (unit => 'a) => Lazy.t('a);

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