Progress on Template Architecture #30
Description
I've been working on Respect\Template this week and achieved a nice result. My current branch has some killing features:
<?php
use Respect\Template\Html;
$template = new Html('template.html');
$template['posts']->items('ul', 'li', Html::named(
'title' => Html::text('h3'),
'text' => Html::text('section'),
'date' => Html::text('footer time'),
'author' => Html::named(
'name' => Html::text('.fn')
)
));
$posts = array(
array(
'title' => 'Hello',
'title' => 'Hello World',
'date' => '2012-10-10',
'author' => array('name' => 'Gaigalas'),
),
array(
'title' => 'Lorem',
'title' => 'Lorem Ipsun',
'date' => '2013-10-10',
'author' => array('name' => 'Gaigalas'),
),
);
$template->render($posts);Given this template:
<ul>
<li>
<article>
<h3>Some Blog Title!</h3>
<section>Some Blog text...</section>
<footer>
<time>2000-01-01</time>
<span class="vcard fn">John</span>
</footer>
</article>
</li>
</ul>Would produce this:
<ul>
<li>
<article>
<h3>Hello</h3>
<section>Hello World</section>
<footer>
<time>2012-10-10</time>
<span class="vcard fn">Gaigalas</span>
</footer>
</article>
</li>
<li>
<article>
<h3>Lorem</h3>
<section>Lorem Ipsum</section>
<footer>
<time>2013-10-10</time>
<span class="vcard fn">Gaigalas</span>
</footer>
</article>
</li>
</ul>There are some other tricks as well. One of them is selective compilation. All templates can be run in real time or compiled in any state. When I say any state, I mean this:
Compiling a template without value:
$template = new Html('template.html');
$template['title']->text('h3');
$template->compile();
Will generate something similar to <h3><?php echo $title;?></h3> in the final compilation. Now, in any moment, if you feed this template with data before compilation:
$template = new Html('template.html');
$template['title']->text('h3');
$template->compile(array('title' => 'Hello'));
Since the result is compiled selectively, now we have <h3>Hello</h3> in our compiled PHP template. This is a huge performance tool that can save a lot of template logic that doesn't change often like translations, page titles, some links =)
All of this is sort of working. Two of the main operators (the abstraction for a template operation) are not compiling their results yet (but they work in real time).
Most of this is tested (behavior style) and doc-commented. I broke BC with the old Template =(
I'm pushing this into the develop branch. Please review!
