Event Emitter w some bonuses

Last updated at: 04-JAN-2016 9:43 GMT-2

IMPORTANT:

1. Events will always have '^' added as prefix and '$' as suffix. This way we avoid collateral effects on the Regex usage.

Without this approach, a listener to event 'A' would receive messages from 'A','AA','AB','AZCZXC', and any other starting w A. I understand thar unless you add a wildcard to your listen string, you want events to match on a ONE ON ONE BASIS.

Now, in case you want to listen to all 'A.*' events, use the regex with .* (dot-star) at the end; Anything w 'A' in the middle? '.*A.*'

This is a replacement for standard EventEmitter, allows usage of Regex. Except for this, it behaves the same way the standard Event Emitter, please see below:

var XtraEmitter = require('xtraemitter);
it('Should Run On Regex', function (done) {
    var e    = new XtraEmitter();
    var noXs = 0;
    e.on('A.*', function (a) {
    	assert.equal('a', a);
    });
    e.on('XX.*', function (x) {
    	assert.equal('x', x);
    	noXs++;
         });
    e.on('END', function () {
    	assert.equal(2, noXs);
    	done();
    })
    e.emit('AAA', 'a');
    e.emit('XXX', 'x');
    e.emit('XXY', 'x');
    e.emit('END');
});
