Module `Ecaml.Position`

A "position" is the index of a character in the text of a buffer. More precisely, a position identifies the place between two characters (or before the first character, or after the last character), so we can speak of the character before or after a given position. However, we often speak of the character "at" a position, meaning the character after that position.

Positions are usually represented as integers starting from 1, but can also be represented as "markers"--special objects that relocate automatically when text is inserted or deleted so they stay with the surrounding characters.

(Info-goto-node "(elisp)Positions").

include Ecaml_value.Value.Subtype

type t = private Ecaml_value.Value.t

We expose private value for free identity conversions when the value is nested in some covariant type, e.g. (symbols : Symbol.t list :> Value.t list) rather than List.map symbols ~f:Symbol.to_value.

val sexp_of_t : t -> Sexplib0.Sexp.t

val eq : t -> t -> bool

eq t1 t2 = Value.eq (to_value t1) (to_value t2), i.e. eq checks whether the Emacs values underlying t1 and t2 are physically equal. This is different than phys_equal t1 t2, because we don't always wrap eq Emacs values in phys_equal OCaml values. I.e. phys_equal t1 t2 implies eq t1 t2, but not the converse.

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).
