Configuration

 
    defaultConfiguration =

Adds additional logging at various points

 
        debug: false

Prevents extending jQuery and Backbone classes with the Synapse -methods

 
        noConflict: false

Default DOM events. When a DOM element is declared the subject of a -binding and no event is specified, the element will be compared to -each item in this list in order to determine the appropriate DOM -event to use. Note that more specific selectors should be listed first -to ensure those events are selected before less selective selectors are -encountered.

 
        domEvents: [
-            ['a,:button,:reset', 'click']
-            ['select,:checkbox,:radio,textarea', 'change']
-            [':submit', 'submit']
-            [':input', 'keyup']
-        ]

The default DOM event to be used if none was detected from the above -list. If not defined, an error will be thrown for undetected events.

 
        defaultDomEvent: null

Default element interfaces relative to their selectors. Each -item will be iterated over in order and compared against using -the jQuery.fn.is() method for comparison. Note that more -specific selectors should be listed first to ensure those events are -selected before less selective selectors are encountered.

 
        elementInterfaces: [
-            [':checkbox,:radio', 'checked']
-            ['button', 'html']
-            [':input', 'value']
-        ]

The default element interface to be used if none was detected from -the above list. If not defined, an error will be thrown for undetected -interfaces.

 
        defaultElementInterface: 'text'

An array of element attributes to check for a value during interface -detection. This value will be used for the opposite interface.

 
        elementBindAttributes: ['name', 'role']

A Synapse object can be defined before script initialization to -provide the configuration.

 
    configuration = @Synapse or {}

Fill in the rest of the default configurations

 
    _.defaults(configuration, defaultConfiguration)

Supported Types

- -

An enumeration of supported object types including:

- -
    -
  • any object (fallback)
    • -
  • jQuery and DOM elements
    • -
  • Backbone.Model objects
    • -
  • Backbone.Collection objects
    • -
  • Backbone.View objects
    • -
 
    Types =
-        object: 0
-        jquery: 1
-        model: 2
-        collection: 3
-        view: 4
-
-    TypeNames =
-        0: 'Object'
-        1: 'jQuery'
-        2: 'Model'
-        3: 'Collection'
-        4: 'View'
-
-    getObjectType = (object) ->
-
-        if object instanceof jQuery
-            return Types.jquery
-
-        if object instanceof Backbone.Model
-            return Types.model
-
-        if object instanceof Backbone.Collection
-            return Types.collection
-
-        if object instanceof Backbone.View
-            return Types.view
-
-        return Types.object

The Synapse constructor acts as a common adapter between objects -providing a common interface for each type of object.

 
    Synapse = (object) -> new Synapse.fn.init(object)
-
-    Synapse.guid = 1
-    Synapse.cache = {}
-    Synapse.version = '0.2'
-    Synapse.configuration = configuration
-
-    Synapse.fn = Synapse:: =
-
-        constructor: Synapse

Keep references to all observers and subjects via their guid, the -corresponding event, and whether it is an active connection. -{ 3: [event, true] }. So the necessary objects can be deferenced -when observing is turned off.

 
        observers: {}
-        subjects: {}

Constructor

- -

Ensure the context is not already an instance of Synapse. -Strings and DOM elements are converted to jQuery objects and the -original context is stored for safe-keeping. The type is -determined for inferring the interfaces.

 
        init: (context) ->
-            if context instanceof Synapse then return context
-
-            if _.isString(context) or _.isElement(context)
-                @originalContext = context
-                context = jQuery.apply(jQuery, arguments)
-
-            @context = context
-            @type = getObjectType(context)
-
-            Synapse.cache[@guid = Synapse.guid++] = @

Bind/Unbind/Trigger

- -

The common interface between all objects are the bind, -unbind, and trigger methods. The native methods are used if -available and fallback to the methods defined on the -Backbone.Events module.

 
        bind: ->
-            bind = @context.bind or Backbone.Events.bind
-            bind.apply @context, arguments
-
-        unbind: ->
-            unbind = @context.unbind or Backbone.Events.unbind
-            unbind.apply @context, arguments
-
-        trigger: ->
-            trigger = @context.trigger or Backbone.Events.trigger
-            trigger.apply @context, arguments

Get/Set

- -

The second shared interface between all objects are the get and -set methods. The appropriate method of invocation is chosen -depending on the object type. If a jQuery object, the built-in -interfaces are used. The key will be checked on all other objects -to be a method, and then checked for a local get/set method. -The fallback (e.g. object primitives) is to return or set the object -property.

 
        get: (key) ->
-            if @type is Types.jquery
-                return Synapse.interfaces.get(@context, key)
-
-            if _.isFunction(@context[key])
-                return @context[key]()
-
-            if @context.get
-                return @context.get.call(@context, key)
-
-            return @context[key]
-
-        set: (key, value) ->
-            if not _.isObject(key)
-                attrs = {}
-                attrs[key] = value
-            else
-                attrs = key
-
-            if @type is Types.jquery
-                for k, v of attrs
-                    Synapse.interfaces.set(@context, k, v)
-            else if _.isFunction(@context[key])
-                @context[key](value)
-            else if @context.set
-                @context.set.call(@context, attrs)
-            else
-                _.extend @context, attrs
-
-            return @
-
-        sync: (other) ->
-            if not (other instanceof Synapse)
-                other = Synapse(other)
-            @observe(other).notify(other)
-
-        observe: (other, args...) ->
-            if not (other instanceof Synapse)
-                other = Synapse(other)
-            connect(other, @, args...)
-            return @
-
-        notify: (other, args...) ->
-            if not (other instanceof Synapse)
-                other = Synapse(other)
-            connect(@, other, args...)
-            return @
-
-        toString: -> "<Synapse #{TypeNames[@type]} ##{@guid}>"
-
-    Synapse.fn.init:: = Synapse.fn

Iterates over each selector and event in domEvents and -compares it with the subject context (e.g. the jQuery object).

 
    detectDomEvent = (elem) ->
-        elem = jQuery(elem)
-        for item in Synapse.configuration.domEvents
-            [selector, event] = item
-            if elem.is(selector) then return event
-        if Synapse.configuration.defaultDomEvent
-            return Synapse.configuration.defaultDomEvent
-        throw new Error("Event for #{elem} could not be detected.")

Return an array of events for the given subject. if event is not -supplied, attempt to detect the appropriate event for the object type. -An array is used when subjects are being observed via multiple events.

 
    getEvents = (subject, event) ->
-        if not event
-            if subject.type is Types.jquery
-                events = [detectDomEvent(subject.context)]
-            else if subject.type is Types.view
-                events = [detectDomEvent(subject.context.el)]
-            else if subject.type is Types.model
-                events = ['change']
-            else
-                throw new Error('No event defined for subject')
-        else
-            events = if not _.isArray(event) then [event] else event
-
-        return events
-
-    Synapse.getEvents = getEvents

Get/Set Handlers

- -

Default event handlers for the various object types. Each type has a -handler for when it is the subject and for when it is the observer.

 
    defaultHandlers =
-        get: (subject, event, converter, interfaces, set, trigger) ->
-            subject.bind event, ->
-                value = _.map interfaces, subject.get, subject
-
-                if converter
-                    value = converter.apply converter, value
-                    if not _.isArray(value)
-                        value = [value]
-
-                set.apply subject.context, value
-
-            if trigger then subject.trigger event
-
-
-        set: (observer, interfaces) ->
-            return (args...) ->

for each setter interface defined, use the value for each

 
                for interface in interfaces
-                    observer.set interface, args...
-
-
-    getHandlerForType = (type, method) ->
-        if not (handler = Synapse.handlers[type]?[method])
-            handler = defaultHandlers[method]
-        return handler
-
-
-    Synapse.handlers =
-        2:

Model get Handler

- -

The default event for models is change. Interfaces correspond -to model attributes in this context, thus defining events such as -change:title. For alternate events, interfaces may not need -be defined.

- -

Although each event/interface combination has a separate handler, -values received from all interfaces are passed to the set -handler (and converter if defined).

- -

Finally, if trigger the event which is typically used to fill -the observer with the initial values.

 
            get: (subject, event, converter, interfaces, set, trigger) ->
-                _event = event
-                for attr in interfaces
-                    if attr and not _.isFunction(subject.context[attr])
-                        _event = "#{event}:#{attr}"
-
-                    subject.bind _event, (model, value, options) ->
-                        value = _.map interfaces, subject.get, subject
-
-                        if converter
-                            value = converter.apply converter, value
-                            if not _.isArray(value)
-                                value = [value]
-
-                        set.apply subject.context, value
-
-                    if trigger
-                        subject.trigger _event, subject.context, subject.get(attr)
-
-            set: (observer, interfaces) ->
-                return (args...) ->
-                    attrs = {}
-                    for [k, v] in _.zip(interfaces, args)
-                        attrs[k] = v
-                    observer.set attrs

Create a Connection

- -
    -
  • event - the event that will trigger the subjectInterface to be -invoked
    • -
  • subjectInterface - the interface for getting a value from the subject
    • -
  • observerInterface - the interface for setting a value on the observer
    • -
  • converter - an intermediate function that transforms the value received -before passing it to the observerInterface
    • -
  • triggerOnBind - defines when or not to trigger the event once bound -acting as the initial invocation.
    • -
 
    defaultRegisterOptions =
-        event: null
-        subjectInterface: null
-        observerInterface: null
-        converter: null
-        triggerOnBind: true

The workhorse which sets up a single connection between the subject -and observer. Note, the subject and observer are already -Synapse instances.

 
    connectOne = (subject, observer, options) ->
-
-        _.defaults(options, defaultRegisterOptions)
-
-        events = getEvents(subject, options.event)
-
-        [subjectInterface, observerInterface] = getInterfaces(subject, observer,
-            options.subjectInterface, options.observerInterface)
-
-        if (converter = options.converter) and not _.isFunction(converter)
-            converter = observer[converter]
-
-        triggerOnBind = options.triggerOnBind
-
-        getHandler = getHandlerForType(subject.type, 'get')
-        setHandler = getHandlerForType(subject.type, 'set')
-
-        setHandler = setHandler(observer, observerInterface)
-
-        for event in events
-            subject.observers[observer.guid][event] = true
-            observer.subjects[subject.guid][event] = true
-
-            getHandler(subject, event, converter, subjectInterface, setHandler, triggerOnBind)

Defines multiple connections between two objects via the -interfaces specified. A few shorthand arguments that can be passed -include:

- -
    -
  • subject, observer, converter - interfaces are detected -with a converter. Useful for simple data transformations e.g. raw data → -HTMLified
    • -
  • subject, observer, subjectInterface, observerInterface - -one or both interfaces are explicitly defined. The direction is always -subject → observer, thus the subject interface is specified -first.
    • -
  • subject, observer, options - an options object can be -passed specifying one or all of the connection options, including the -event that will trigger the pipeline.
    • -
  • subject, observer, ...
    • -
 
    connect = (subject, observer, args...) ->
-        if not subject.observers[observer.guid]
-            subject.observers[observer.guid] = {}
-
-        if not observer.subjects[subject.guid]
-            observer.subjects[subject.guid] = {}
-
-        options = args
-        arg0 = args[0]
-        arg1 = args[1]
-
-        if _.isFunction(arg0)
-            options = converter: arg0
-        else if _.isArray(arg0) or not _.isObject(arg0)
-            options =
-                subjectInterface: arg0
-                observerInterface: arg1

the configuration is already defined as an object

 
        if not _.isArray(options)
-            options = [options]
-
-        for opt in options
-            connectOne(subject, observer, opt)

Iterates over each selector and event in elementInterfaces and -compares it with the subject context (e.g. the jQuery object).

 
    detectElementInterface = (elem) ->
-        elem = jQuery(elem)
-        for item in Synapse.configuration.elementInterfaces
-            [selector, interface] = item
-            if elem.is(selector) then return interface
-        if Synapse.configuration.defaultElementInterface

Return an array of interfaces appropriate for the given subject/observer. -If no interface is defined, only if a name or role attribute on -either the subject or observer will be used by default. The following steps -are invovled in determining the interfaces:

- -
    -
  • each interface is independently determined first, since the other may -be inferred from the other (specifically in the case of DOM elements)
    • -
  • if either are not defined, each is attempted to be determined relative -to the other
    • -
  • elements can use an arbitrary identifier such as the name or -role attribute (e.g. name="title")
    • -
- -

The last step slits the string in case multiple interfaces have been -defined for either side.

- -

Special note: -If no subjectInterface has been set and the subject is a model, assume -the observer wants to observe any change of the model. This generally -assumes a handler of some sorts will be performing any necessary -manipulation.

Interfaces Registry

- -

Simple module allowing for [un]registering interfaces. The get and -set methods are defined here which are used by Synapse instances -as the common interface for jQuery objects.

- -

Compound interfaces correspond to other jQuery APIs such as attr, -prop and data and require their own key, thus the -attr:name convention. In this case, the key will be extracted -and passed as the first argument to the interface handler.

 
    interfaces = do ->
-        registry: {}
-
-        register: (config) ->
-            @registry[config.name] = config
-
-        unregister: (name) ->
-            delete @registry[name]
-
-        get: (context, name, args...) ->
-            if context instanceof Synapse
-                context = context.context
-
-            [name, key] = name.split ':'
-            if key? then args = [key].concat(args)
-            @registry[name].get.apply(context, args)
-
-        set: (context, name, args...) ->
-            if context instanceof Synapse
-                context = context.context
-
-            [name, key] = name.split ':'
-            if key? then args = [key].concat(args)
-            @registry[name].set.apply(context, args)

Built-In interfaces

- -

Each setter and getter for compound interfaces are defined up front -for use throughout the interfaces. For older versions of jQuery, attr -will be used instread of prop.

 
    do ->
-        getProperty = (key) ->
-            if @prop?
-                return @prop(key)
-            getAttribute.call(@, key)
-
-        setProperty = (key, value) ->
-            if @prop?
-                if typeof key is 'object'
-                    return @prop(key)
-                return @prop(key, value)
-            setAttribute.call(@, key, value)
-
-        getAttribute = (key) -> @attr(key)
-
-        setAttribute = (key, value) ->
-            if _.isObject(key) then @attr(key) else @attr(key, value)
-
-
-        getStyle = (key) -> @css(key)
-
-        setStyle = (key, value) ->
-            if _.isObject(key) then @css(key) else @css(key, value)

text

- -

Gets and sets the innerText of the element

 
        interfaces.register
-            name: 'text'
-            get: -> @text()
-            set: (value) -> @text((value or= '').toString())

html

- -

Gets and sets the innerHTML of the element

 
        interfaces.register
-            name: 'html'
-            get: -> @html()
-            set: (value) -> @html((value or= '').toString())

value

- -

Gets and sets the value of the element. This is to be used with form -fields.

 
        interfaces.register
-            name: 'value'
-            get: -> @val()
-            set: (value) -> @val(value or= '')

enabled

- -

Gets and sets the disabled property of the element. The disabled -property is directly related to the truth of the value. That is, if the -value is true the element will be enabled.

 
        interfaces.register
-            name: 'enabled',
-            get: ->
-                !getProperty.call(@, 'disabled')
-            set: (value) ->
-                if _.isArray(value) and value.length is 0
-                    value = false
-                setProperty.call(@, 'disabled', !Boolean(value))

disabled

- -

Gets and sets the disabled property of the element. The disabled -property is inversely related to the truth of the value. That is, if the -value is true the element will be disabled.

 
        interfaces.register
-            name: 'disabled'
-            get: ->
-                getProperty.call(@, 'disabled')
-            set: (value) ->
-                if _.isArray(value) and value.length is 0

-                if _.isArray(value) and value.length is 0
-                    value = false
-                setProperty.call(@, 'checked', Boolean(value))

visible

- -

An implied one-way interface that toggles the element's visibility -based on the truth of the value it is observing.

 
        interfaces.register
-            name: 'visible'

-                getStyle.call(@, 'display') is not 'none'
-            set: (value) ->
-                if _.isArray(value) and value.length is 0
-                    value = false
-                if Boolean(value) then @show() else @hide()

hidden

- -

An implied one-way interface that toggles the element's visibility -based on the truth of the value it is observing.

 
        interfaces.register
-            name: 'hidden'
-            get: ->
-                getStyle.call(@, 'display') is 'none'
-            set: (value) ->
-                if _.isArray(value) and value.length is 0
-                    value = false
