Emacs text, which is a sequence of characters, along with text properties associated with each character.

(Info-goto-node "(elisp)Text")

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 -> Ppx_sexp_conv_lib.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 of_utf8_bytes : string -> t
val to_utf8_bytes : t -> string
val length : t -> int

length t returns the number of characters in t.

val num_bytes : t -> int

num_bytes t returns the number of bytes in the representation of t, which, if is_multibyte t, can be greater than length t. (describe-function 'string-bytes)

val colorize : t -> Color.t -> t
val property_value : t -> at:int -> 'a Property_name.t -> 'a option

property_value t ~at property_name returns the value of property_name for the character after at. at is a zero-based index into t; property_value raises unless 0 <= at <= length t (allowing length is different than OCaml).
