For our current project we required some neat instant user notifications, therefore we created a simple Growl-inspired notification system using Mootools.

Now updated for IE6 compatibility!

Download it here!

The package contains a sample.html very self-explanatory for most users;

Just include the js_growl.js and the js_growl.css files in your page’s header and send a user notification whenever you need using:

JS_Growl.notify('Your text or content html goes here.');

Any bugs/features just give me a comment, i’ll check it out ;)

I’m just finishing our new website and i’ve been posting here the effects i’ve created for it.
This one is a little more “show off”;
It’s the way we’ve set up our portfolio using Fx.Elements for the togglers and Slides for the presentation images.
You can check how it works here.

this is the smooth font resize for css class “.bump” effect.
Just put class=”bump” on the items you want and use the following javascript somewhere on your page.

window.addEvent('domready',function() { 
 
	//scaling values
	var scale_px=6;
	var scale_em=0.3;
 
	var bumps=$$('.bump');
	bumps.each(function(bump, i){
		var init_size=bump.getStyle('font-size');
 
		var units=init_size.match(/em/)!=null ? 'em' : init_size.match(/px/)!=null ? 'px' : false;
		if(units===false) return false;
 
		var size_up=(init_size.toFloat()+(units=='em' ? scale_em : scale_px))+units;
		var fx=new Fx.Morph(bump, {duration:90, wait:false, transition:Fx.Transitions.Back.easeOut});
 
		bump.addEvent("mouseenter", function(event) {
			fx.start({
				'font-size':size_up
			});
		});
		bump.addEvent("mouseleave", function(event) {
			fx.start({
				'font-size':init_size
			});
		});
	});
});

Note: In order for this to work on IE7 you need to have some font-size defined in your css for every “.bump” on your page. Otherwise font-size will return “100%”, and it get’s impossible to know how to resize – i’ve tried it – damn IE :/

You can check it working here, on the links under “We Provide:”.
Tanks :)

being working a lot with mootools, dojo, wordpress and some other frameworks and toolkits lately, my question today is this:
Why, most of the times, don’t frameworks and toolkits developers launch any backward compatibility modules at all?

It might seem pretty complicated getting old deprecated funcionalities working  on newer, better versions, but, apart from some real specific embembed funcionalities, it really shouldn’t be that hard.

For the following example i’ll use Mootools as an explanatory example:

All you need is a nicely designed dynamic version transitioning system.
One that allows you to, anytime on the execution, define which version will the following code run on.

Imagine you design a backward compatibility plugin from version B to version A.
On version C you’ll design a backward compatibility plugin to version B.

So now, on a page running “mootools-C.js” you should include the backward compatibility modules “mootools-back-C-B.js” and “mootools-back-B-A.js”, or a compiled version (having just a copy paste of both previous files content) “mootools-back-C-to-A.js”.

So if you run something like “Mootools.use_version(‘A’);” the dynamic version transitioning system would automatically look for it’s previous version compatilities execution for version B at, let’s suppose, “MootoolsBack_C_B();” and then rerun the same command (“Mootools.use_version(‘A’);”) while already running on version B to travel back to version A (the dynamic version transitioning system, already on version B would run something like “MootoolsBack_B_A();”).

This method would, in theory, work for multiple version transitions without having to design a specific plugin for each version to version compatibility. It would save developers hours in trying to put two different tools, based on two different framework/toolkit versions, together on the same execution – like using both MOOdalbox 1.3 beta 2 and mooflow v0.2 in the same page.

The system would work both ways, as you could “Mootools.version_reset();” or “Mootools.use_version(‘C’);” to travel back to version C on the rest of the execution, the system would run the consecutive version travel functions eg. “MootoolsBack_A_B();” and “MootoolsBack_B_C();” and the rest of the code would be running on Mootools version C.

This “dynamic version transitioning system” will be used for every release transition on NaturePhp.
It might not work perfectly at first, but it will certainly relieve many developers’ headaches.

I hope in the future more and more projects start using a system like this.

i’ve used firefox for development for quite some time now, but on a mac i’ve always liked Safari better for regular web browsing, as it always been much faster and cute.

But the recently released Firefox 3 for Mac really changed my mind. It is, without a doubt, awesome. Runs perfectly smoothly, really nice design, fastest browser ever.

Firefox 2 versions really dragged around with heavy Javascript applications such as Gmail or our upcoming FallForward, but this new version handles javascript even better than Safari 3.
This release has been a really nice boost for my web browsing as i’ve not been much into the latest beta versions of Firefox 3.

The bad part is Firebug still hasn’t come out on it’s official release for Firefox 3. However, i’m using the beta and it works really nice – and everything is perfect again.

A “must have” indeed.

Great work for the guys at Mozilla!!
By the way, great website design for http://www.mozilla.com ;)
