Piwik JS Tracker: Easier way for using multiple trackers

[tsteur]

For example in #9518 we had a case where two scripts declare a Piwik and overwrite each other. In http://developer.piwik.org/guides/tracking-javascript-guide#multiple-piwik-trackers we explain how to use multiple trackers eg by calling

var piwikTracker = Piwik.getTracker(12,  "http://example.com/piwik/" );
piwikTracker.trackPageView();

However, creating the tracker instance is not trivial and is a bit different from the standard async tracker. For example a developer would need to make sure to call methods on the tracker in this order to configure the tracker:

['disableCookies', 'setTrackerUrl', 'setAPIUrl', 'setCookiePath', 'setCookieDomain', 'setDomains', 'setUserId', 'setSiteId', 'enableLinkTracking'];

Otherwise there might be side effects. Also one would have to change all calls to Piwik tracker from say _paq.push(['trackPageView]) to if (piwikTracker) piwikTracker.trackPageView(); etc. which can be a lot of effort.

I wonder if there are easier ways. Eg could we maybe also provide a _paq2, _paq3, _paq4, ...?
We probably don't want to pollute the namespace so maybe we could do something like _paq2 =_paq.create() or paq2 = _paqCreate();. This way one could create unlimited _paq instances manually as needed. All a developer has to do afterwards is to replace _paq with _paq2 and one is done. The order of the applied methods that are applied would be the same as usual etc.

That would be an awesome improvement! Would both trackers register downloads, outlinks, etc?

[tsteur]

Yes I'd say so but I'm not sure if there are any problems with it. I think it should work fine though

So this is working is it?
How can I get the namespace in my tracker, for example, paq2 = _paqCreate(); to a particular tracker if I have 2 trackers. An example would be very helpful.

PR in progress: #10085

BTW it is not 100% going to be solved by #10085. #10085 is only a solution if someone wants to 100% track the same data to both Piwik instances. If someone wants to track different data to different Piwiks a different solution is needed.

Thanks.. Please keep me posted.

@tsteur I would consider also a scenario where somebody uses two Piwik.js scripts from different versions. There is namespace conflict in such situation because all is stored in global Piwik object.
