The type for errors

type warning =
  1. | Variable_or_constant of string * (Stdlib.Lexing.position * Stdlib.Lexing.position)

The type for warnings

exception Error of error

The exception that should be raised when an error occur

val update_loc : Stdlib.Lexing.lexbuf -> string option -> unit

update_loc lexbuf name update the position informations for the lexer

val set_infix : (string * (Stdlib.Lexing.position * Stdlib.Lexing.position)) -> unit

set_infix sym declares sym as a prefix symbol used in an infix position

val unset_infix : unit -> unit

unset_infix () unset the current use of a prefix symbol used in an infix position

val error_msg : error -> string -> string

error_msg e filename returns a string describing the error e while the file filename is being processed

val warnings_to_string : string -> warning list -> string

warnings_to_string filname ws returns a string describing the warnings and their location for the file filename

val get_loc_error : error -> Stdlib.Lexing.position * Stdlib.Lexing.position

get_loc_error e returns the starting and ending position of an error

val get_string_error : error -> string * (Stdlib.Lexing.position * Stdlib.Lexing.position)

get_string_error e returns the string describing the error and its position
