Overrides the Location module of OCaml

There are less functions in this module. However the API should be more stable than the Location module of OCaml.

type t = Astlib.Location.t = {
  1. loc_start : Lexing.position;
  2. loc_end : Lexing.position;
  3. loc_ghost : bool;
}
val in_file : string -> t

Return an empty ghost range located in a given file.

val set_filename : t -> string -> t

Set the pos_fname both in loc_start and loc_end. Leave the rest as is.

val none : t

An arbitrary value of type t; describes an empty ghost range.

val init : Lexing.lexbuf -> string -> unit

Set the file name and line number of the lexbuf to be the start of the named file.

val raise_errorf : ?loc:t -> ('a, Stdppx.Caml.Format.formatter, unit, 'b) Pervasives.format4 -> 'a

Raise a located error. The exception is caught by driver and handled appropriately

val of_lexbuf : Lexing.lexbuf -> t

Return the location corresponding to the last matched regular expression

val report_exception : Stdppx.Caml.Format.formatter -> exn -> unit

Report an exception on the given formatter

val print : Stdppx.Caml.Format.formatter -> t -> unit
