Module Base.Source_code_position

One typically obtains a Source_code_position.t using a [%here] expression, which is implemented by the ppx_here preprocessor.

type t = Caml.Lexing.position = {
pos_fname : string;
pos_lnum : int;
pos_bol : int;
pos_cnum : int;
}

See INRIA's OCaml documentation for a description of these fields.

sexp_of_t uses the form "FILE:LINE:COL", and does not have a corresponding of_sexp.

val (>=) : t -> t -> bool
val (<=) : t -> t -> bool
val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val to_string : t -> string

to_string t converts t to the form "FILE:LINE:COL".

val of_pos : (string * int * int * int) -> t

of_pos Caml.__POS__ is like [%here] but without using ppx.
