Module `Ecaml.Window`

A "window" in Emacs is the physical area of the screen in which a buffer is displayed.

Each window has its own value of point, independent of the value of point in other windows displaying the same buffer. This makes it useful to have multiple windows showing one buffer.

A window is "live" as long as it displays a buffer. All functions other than is_live raise if supplied a t such that not (is_live t).

type value
type t = private value: 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.
