README

Simple context sensitive HTML template engine. Yes, yet another one.

Synopsis

See an examples.

Template example:

<a href={ link } title={ title && "Foo bar: ${ title }" }>
    <span id=foobar class='it parses html'>
        { description }
    </span>
    <span>
        {# comment #}
    </span>
</a>

Creating data for the template above:

use VovanVE\HtmlTemplate\runtime\RuntimeHelper;

$runtime = new RuntimeHelper([
    'link' => 'http://example.com?foo=bar&lorem=ipsum#hash',
    'title' => 'Lorem <ipsum> "dolor" sit amet',
    'description' => function () {
        return 'Some <text/plain> content';
    },
]);

Run a template when everything is prepared. Here foobar is a template's name covered by Template Provider.

echo $engine->runTemplate('foobar', $runtime);

The output for the example above (wrapped manually only here):

<a href="http://example.com?foo=bar&amp;lorem=ipsum#hash"
title="Foo bar: Lorem &lt;ipsum&gt; &quot;dolor&quot; sit amet"
><span id="foobar" class="it parses html"
>Some &lt;text/plain&gt; content</span><span></span></a>

Template code compiles to PHP code behind the scene. It may look something like so (formatted manually only here for demonstration):

($runtime::createElement('a', [
    'href'  => ($runtime->param('link')),
    'title' => (!($_ta=($runtime->param('title')))
        ? $_ta
        :(('Foo bar: '.($runtime->param('title'))))
    )
], [
    ($runtime::createElement('span', [
        'id'    => 'foobar',
        'class' => 'it parses html'
    ], [
        ($runtime::htmlEncode(($runtime->param('description'))))
    ])),
    '<span></span>'
]))

Compiler will evaluate as much constant expressions as possible and as much as it learned to. For example, completely constant template like following:

<div>{true && 'Lorem < ipsum dolor'}</div>

will be compiled to:

'<div>Lorem &lt; ipsum dolor</div>'
