(* located exceptions *)
exception Exc of Loc.t * exn
(** [Ploc.Exc loc e] is an encapsulation of the exception [e] with
the input location [loc]. To be used to specify a location
for an error. This exception must not be raised by [raise] but
rather by [Ploc.raise] (see below), to prevent the risk of several
encapsulations of [Ploc.Exc]. *)
val raise : Loc.t -> exn -> 'a
(** [Ploc.raise loc e], if [e] is already the exception [Ploc.Exc],
re-raise it (ignoring the new location [loc]), else raise the
exception [Ploc.Exc loc e]. *)
val make_unlined : int * int -> Loc.t
(** [Ploc.make_unlined] is like [Ploc.make] except that the line number
is not provided (to be used e.g. when the line number is unknown. *)
val dummy : Loc.t
(** [Ploc.dummy] is a dummy location, used in situations when location
has no meaning. *)
(* combining locations *)
val sub : Loc.t -> int -> int -> Loc.t
(** [Ploc.sub loc sh len] is the location [loc] shifted with [sh]
characters and with length [len]. The previous ending position
of the location is lost. *)
val after : Loc.t -> int -> int -> Loc.t
(** [Ploc.after loc sh len] is the location just after loc (starting at
the end position of [loc]) shifted with [sh] characters and of length
[len]. *)
