Default is `Ignore.

type ('input, 'result) t

The component type (('input, 'result) Bonsai.t) can be thought of as a function from 'model to 'result, but where the 'result can schedule events of the component's "action type". These actions are used to produce a new 'model which in turn causes the 'result to be recomputed. Instances of the 'result type can contain callbacks which schedule actions when interacted with by user (via button click, text input, etc). These actions are handled by the component's apply_action function, which yields a new model to be displayed.

val sexp_of_t : (_, _) t -> Core_kernel.Sexp.t
val input : ('input, 'input) t

A bonsai component that just forwards the input straight through to the result. This is equivalent to Bonsai.pure ~f:Fn.id.

Component Constructors

val const : 'result -> (_, 'result) t

Returns a component with no action or model, only a constant result.

val pure : f:('input -> 'result) -> ('input, 'result) t

A pure function with no model from 'input to 'result

val compose : ('i1, 'r1) t -> ('r1, 'r2) t -> ('i1, 'r2) t

compose a b joins a and b together such that the result of a is used as the input of b.

module type S = sig ... end

Many modules have the same shape, they declare the model, action, and result of the component, and then define apply_action and view over those types.

type ('input, 'model, 'action, 'result) component_s = (module S with type Action.t = 'action and type Input.t = 'input and type Model.t = 'model and type Result.t = 'result)
module M : functor (Component : S) -> sig ... end
val of_module : ('input, 'model, 'action, 'result) component_s -> default_model:'model -> ('input, 'result) t
module type Enum = sig ... end
val enum : (module Enum with type t = 'key) -> which:('input -> 'key) -> handle:('key -> ('input, 'result) t) -> ('input, 'result) t
val if_ : ('input -> bool) -> then_:('input, 'result) t -> else_:('input, 'result) t -> ('input, 'result) t

if_ is a simple application of enum to (module Bool).

module Infix : sig ... end

For composing components which share the same model. For example, applying an action in one component changes the shared model, which is reflected in the results of the other component.

val map_input : ('i2, 'result) t -> f:('i1 -> 'i2) -> ('i1, 'result) t

Transforms the input of a component. The signature of f is reversed from most other map functions.
