nut 0.4.2
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);
