Binding with JS values.

type t

The universal type representing arbitrary JS values.

Mapper for built-in types

val t_of_js : t -> t

val t_to_js : t -> t

val string_of_js : t -> string

val string_to_js : string -> t

val int_of_js : t -> int

val int_to_js : int -> t

val bool_of_js : t -> bool

val bool_to_js : bool -> t

val float_of_js : t -> float

val float_to_js : float -> t

val array_of_js : (t -> 'a) -> t -> 'a array

val array_to_js : ('a -> t) -> 'a array -> t

val list_of_js : (t -> 'a) -> t -> 'a list

val list_to_js : ('a -> t) -> 'a list -> t

val array_of_js_from : (t -> 'a) -> t -> int -> 'a array

val list_of_js_from : (t -> 'a) -> t -> int -> 'a list

val option_of_js : (t -> 'a) -> t -> 'a option

Both null and undefined are mapped to None.

val option_to_js : ('a -> t) -> 'a option -> t

None is mapped to null.

Wrap OCaml functions as JS functions

val fun_to_js : int -> (t -> 'a) -> t

Wrap an OCaml function of known arity (>=1) into a JS function. Extra arguments are discarded and missing argument are filled with 'undefined'.

val fun_to_js_args : (t -> 'a) -> t

Wrap an OCaml function taking JS arguments as a JS array.

JS objects

val get : t -> string -> t

val set : t -> string -> t -> unit

val obj : (string * t) array -> t

val empty_obj : unit -> t

val has_property : t -> string -> bool

val iter_properties : t -> (string -> unit) -> unit

Calling JS functions

val call : t -> string -> t array -> t

Call a method on an object (binding 'this' to the object).

val apply : t -> t array -> t

Call a function.

val new_obj : t -> t array -> t

Call a constructor

val call_arr : t -> string -> t -> t

Variant of Ojs.call where the arguments are passed as an already built JS array.

val apply_arr : t -> t -> t

Variant of Ojs.apply where the arguments are passed as an already built JS array.

val new_obj_arr : t -> t -> t

Variant of Ojs.new_obj where the arguments are passed as an already built JS array.

Arrays

val array_make : int -> t

val array_get : t -> int -> t

val array_set : t -> int -> t -> unit

Misc

val global : t

val null : t

val variable : string -> t

val type_of : t -> string

class obj : t -> object ... end

val delete : t -> string -> unit

val is_null : t -> bool

val obj_type : t -> string

Returns: "object Array" "object Object" "object Number" "object String" "object Null" "object Boolean"
