module Stdpp: sig end
Standard definitions.
exception Exc_located of ((int * int) * exn)
Exc_located loc e
is an encapsulation of the exception e
with
the input location loc
. To be used in quotation expanders
and in grammars to specify some input location for an error.
Do not raise this exception directly: rather use the following
function raise_with_loc
.
val raise_with_loc : int * int -> exn -> 'a
raise_with_loc loc e
, if e
is already the exception Exc_located
,
re-raise it, else raise the exception Exc_located loc e
.
val line_of_loc : string -> int * int -> string * int * int * int
line_of_loc fname loc
reads the file fname
up to the
location loc
and returns the real input file, the line number
and the characters location in the line; the real input file
can be different from fname
because of possibility of line
directives typically generated by /lib/cpp.
val loc_name : string ref
Name of the location variable used in grammars and in the predefined
quotations for OCaml syntax trees. Default: loc
