Non-fatal user errors
Warnings are user errors that cannot be proper errors for backward compatibility reasons
val emit :
?loc:Stdune__.Loc0.t ->
?hints:User_message.Style.t Pp.t list ->
?is_error:bool ->
User_message.Style.t Pp.t list ->
unitEmit 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 emit_message : User_message.t -> unitemit_message m is like emit, but allow you to provide the message as m instead of the arguments to construct the messagee.
val set_reporter : (User_message.t -> unit) -> unitSet the warning reporter. The default one is User_message.prerr.
