The concise CSS selector engine

nut 0.4.2

Since querySelector is supported by all modern browsers, please consider this library as obsolete.

Nut is a concise query selector engine that just allows you to do extremely simple queries.

Install

You can pick the minified library or install it with :

jam install nut
bower install nut
npm install nut --save-dev

Quickly

Hey, the names branch supports name attributes! Thanks to Crydust ;)

Oh jeez, another engine?!

Nut aims to be minimal to have a very tiny footprint and extreme velocity based on the observation that much of CSS requests could be kept as simple as possible since javascript is able to handle a lot of things. It is most of the time faster than querySelectorAll and then faster than all selector engines. Nut does not implement request caching, to avoid unecessary code additions and performance loss, because the user can easily keep a request and pass it as a context to another request.

Use

Here's it can handle :

#foo
section
.bar p
section #foo .bar p
div, #foo, .bar

And here's it can't :

div *
div#foo div.bar
div > p
div + p

So, all pseudo-classes, attribute selectors and other advanced syntax are not allowed. But, let's dig in it :

// Return an array
nut('#foo');

Of course, queries can have a context :

// Get nodes from the #foo context
nut('.bar p',nut('#foo')[0]);

And that's all you need to know ;)

Ender integration

Nut is compatible with ender and supports some useful syntax.

Selecting nodes, as usually:

$('#foo');
$('.bar p',$('#foo')[0]);

Selecting existing nodes:

var nodes=$('.bar');
$(nodes);

nut's Issues

Remove hard-coded ender dependency

We better separate it from nut and provide two minified file versions.

Node creation

Update that functionnality for ender.js

Add it to Bower packages

Hello!

Maybe you should add this library to bower packages.

Joker syntax

Maybe should we drop * syntax? It's rarely useful, we can retrieve all nodes easily (even with nut, with , separators). So it seems to take useless bytes and performance...
