Module Ecaml.Char_code

A character code is an integer representing a character. Emacs character codes are a superset of the Unicode standard.

include Value.Subtype
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.

include sig ... end
val sexp_of_t : t ‑> Base.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.

include Core_kernel.Equal.S with type t := t
type t
val of_int_exn : int ‑> t
val to_int : t ‑> int
val of_char_exn : char ‑> t

of_char_exn char raises if char isn't ASCII, i.e. if Char.to_int char >= 128.

val min_value : t

zero

val max_value : t
