Your plugin

Create your plugin

var MyPlugin = Embryo.Plugin.extend({
    name: 'MyPlugin',				// your plugin's name
    options: {
        option1: 'value1',			// your plugin's options...
        option2: 'value2',
        option3: 'value3'
    },
    init: function() {				// your plugin's constructor

    },
    //
    // Embryo execute this function for all class creation
    // o: class properties
    // debug: debug mode for this plugin
    // child: class's prototype
    //
    exec: function( o, debug, child ) {

	// Check if your plugin is blacklisted for this class
        if (this.isBlacklisted( o )) {
            debug && console.log( '[' + this.name + '] - SKIPPED' )
            return o
        }

	// if debug mode is enabled for this plugin,
	// show all class property before class creation
        debug && debug( this.name, 'BEFORE', o )

        // your plugin's code...        

	// if debug mode is enabled for this plugin,
	// show all class property after class creation
        debug && debug( this.name, 'AFTER', o )

	// return new class properties
        return o
    }
})

// Create an instance of your plugin
var myPlugin = new MyPlugin()

// Tell embryo to use your new plugin
// use( plugin, debug )
Embryo.use( myPlugin, false )

// Now, you will able to reconfigure your plugin later...
Embryo.plugins('MyPlugin').configure({
	option1: 'value1',					// your plugin's options...
	option2: 'value2',
	option3: 'value3'
})
