BO

A minimal implementation of LightTable's BOT Architecture.

BO can be used to glue different parts within the application with behaviors. It can help augment the Data Flow in javelin with

• Data Store
• Control Flow

• Entity Systems

Protocol

(defprotocol IBO
  (add [this object-name object-map])
  (get-object [this object-name])
  (get-in-object [this object-name object-keys])
  (update! [this object-name object-map])
  (update-in! [this object-name object-keys value])
  (rm [this object-name])
  (objects [this])
  (by-prop [this meta-info matcher])
  (raise [this event-name input]))

Example

(ns tailrecursion.bo.test
  (:require [tailrecursion.bo :as bo]))

(enable-console-print!)

(let [test-bo (bo/BO. (atom {}) (atom {:pc nil :frame []}))]
  (bo/add test-bo :foo {:type :object :data 1 :behaviors [:baz]})
  (bo/add test-bo :bar {:type :object :data 0})
  (bo/update-in! test-bo :bar [:data] 2)
  (println (bo/get-in-object test-bo :bar [:data]))
  (bo/add test-bo :baz {:type :behavior
                        :events [:e]
                        :action (fn [this event-name input obj-name]
                                  (println (str "got " input " for " obj-name " from " event-name)))
                       })
  (bo/raise test-bo :e 5))

2
got 5 for :foo from :e
