Module Stdune.User_warning

Non-fatal user errors

val emit : ?⁠loc:Stdune__Loc0.t -> ?⁠hints:User_message.Style.t Pp.t list -> ?⁠is_error:bool -> User_message.Style.t Pp.t list -> unit

Emit a user warning. The arguments are interpreted in a similar fashion to User_error.raise except that the first paragraph is prefixed with "Warning: " rather than "Error: ".

If is_error is true, then this function behaves exactly the same as User_error.raise.

val set_reporter : (User_message.t -> unit) -> unit

Set the warning reporter. The default one is User_message.prerr.
