Module `Camlon.Location`Source

Source code locations (ranges of positions), used in parsetree.

Sourcetype t = {

loc_start : Lexing.position;
loc_end : Lexing.position;
loc_ghost : bool;

}

Note on the use of Lexing.position in this module. If pos_fname = "", then use !input_name instead. If pos_lnum = -1, then pos_bol = 0. Use pos_cnum and re-parse the file to get the line and character numbers. Else all fields are correct.

Sourceval none : t

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

Sourceval in_file : string -> t

Return an empty ghost range located in a given file.

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

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

Sourceval curr : Lexing.lexbuf -> t

Get the location of the current token from the lexbuf.

Sourceval symbol_rloc : unit -> t

Sourceval symbol_gloc : unit -> t

Sourceval rhs_loc : int -> t

rhs_loc n returns the location of the symbol at position n, starting at 1, in the current parser rule.

Sourceval warning_printer : (t -> Format.formatter -> Warnings.t -> unit) ref

Hook for intercepting warnings.

Sourceval default_warning_printer : t -> Format.formatter -> Warnings.t -> unit

Original warning printer for use in hooks.

Sourceval print_filename : Format.formatter -> string -> unit

Sourceval absolute_path : string -> string

Sourceval show_filename : string -> string

In -absname mode, return the absolute path for this filename. Otherwise, returns the filename unchanged.
