freactive

Work in progress!

Simple functional reactive programming for Clojure.

Defines a function reactive which takes a function as an argument and returns a clojure.lang.IDeref whose value is flagged to be recomputed every time a reactive dependency is updated. (Dirty reactive values are only recomputed when they are dereferenced).

How can a reactive dependency be updated?

freactive has a reactive atom implementation which will be registered as a reactive dependency when reactive computations are computed based on it.

(ns freactive.core-test
  (:refer-clojure :exclude [atom swap!])
  (:require [freactive.core :refer
             [reactive atom swap!]]))

(def a (atom 0))

(def b (atom 0))

(def r (reactive (fn [] (+ @a @b))))

@r
;; 0

(swap! a inc)
;; 1

@r
;; 1

(swap! b inc)
;; 1

@r
;; 2

Coming soon: reactive agent and ref
