Module Buffer_local.Wrap

Idiomatic usage of Wrap looks like:

Buffer_local.Wrap.(SYMBOL_NAME <: TYPE)

For example:

Buffer_local.Wrap.("default-directory" <: string)

To use ~make_buffer_local_always:true, the idiom is:

Buffer_local.Wrap.(
  let ( <: ) = ( <: ) ~make_buffer_local_always:true in
  SYMBOL_NAME <: TYPE)
val (<:) : ?⁠make_buffer_local_always:bool -> string -> 'a Ecaml__.Import.Value.Type.t -> 'a t
include Ecaml__.Import.Value.Type.S
type value
type 'a t
val create : Core_kernel.Sexp.t -> ('a -> Core_kernel.Sexp.t) -> (value -> 'a) -> ('a -> value) -> 'a t
val with_of_value_exn : 'a t -> (value -> 'a) -> 'a t
val to_sexp : 'a t -> 'a -> Core_kernel.Sexp.t
val bool : bool t
val float : float t
val ignored : unit t
val int : int t
val string : string t
val string_cached : string t

string_cached is like string, except it uses of_utf8_bytes_cached.

val unit : unit t
val value : value t
val list : 'a t -> 'a list t
val vector : 'a t -> 'a array t
val array_as_list : 'a t -> 'a array t

Represent an ocaml array as an elisp list, without creating an intermediate ocaml list.

val option : 'a t -> 'a option t

option represents None as nil and Some a as cons v nil, where v is the representation of a.

val nil_or : 'a t -> 'a option t

nil_or t_ represents None as nil and Some a as v, where v is the representation of a. This is a common representation used by Elisp functions. But it is only correct if nil is not a representation of any value in t; in that situation use Type.option_.

val alist : 'a t -> 'b t -> ('a * 'b) list t
val tuple : 'a t -> 'b t -> ('a * 'b) t

Represent a tuple (a,b) as the elisp cons cell (a . b)

val tuple2_as_list : 'a t -> 'b t -> ('a * 'b) t

Represent a tuple (a,b) as the elisp list '(a b)

val sexpable : (module Core_kernel.Sexpable with type t = 'a) -> name:Core_kernel.Sexp.t -> 'a t

Embed a sexpable ocaml type, so we can save values of the type in emacs, e.g. as buffer local variables

val path_list : string list t

A list of directories. Each element is a string (directory name) or nil (try default directory). nil values are converted to ".", which has the same meaning.
