Embeds in <pre> tags about embera HOT 3 CLOSED

Hi sunnysingh,

Thats a good idea but I dont have time to implement it right now. Perhaps for the next big version I'll be able to add an html aware option.

As a workaround you could just extract the data inside the <pre></pre> tags, pass the text through Embera and put the extracted data back inside the <pre> tags again.

Try with something like this:

$text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. consectetur, ac dignissim https://www.youtube.com/watch?v=yzTuBuRdAyA .
<pre>
   Etiam scelerisque rutrum justo, https://www.youtube.com/watch?v=yzTuBuRdAyA 
</pre>';

$holder = array();
if (strpos($text, '<pre') !== false) {
    // Reserve the content inside the <pre> tags
    $text = preg_replace_callback('/\\s*(<pre\\b[^>]*?>[\\s\\S]*?<\\/pre>)\\s*/i', function ($content) use (&$holder) {
        $placeholder = '%' . md5(time() . count($holder) . mt_rand(0, 500)) . '%';
        $holder[$placeholder] = $content['1'];
        return $placeholder;
    }, $text);
}

$embera = new \Embera\Embera();
$text = $embera->autoEmbed($text);

if (!empty($holder)) {
    $text = str_replace(array_keys($holder), array_values($holder), $text);
}

echo $text;

I think that should work, however you can organize the code better. I would create a new class called something like ReserveTag and put the logic into it.

By doing this you end up with something like this:

$text = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. consectetur, ac dignissim https://www.youtube.com/watch?v=yzTuBuRdAyA .
<pre>
   Etiam scelerisque rutrum justo, https://www.youtube.com/watch?v=yzTuBuRdAyA 
</pre>';

$reserve = new ReserveTag('pre');
$embera = new \Embera\Embera();
$text = $embera->autoEmbed($reserve->filter($text));
echo $reserve->restore($text);

Tell me if it helps! Like I said, I'll look into implementing something like that on the next major version.

This is the best reply that I've seen, I really appreciate in you providing me a code sample and I can't believe that I didn't think of doing it this way.

Your code definitely works for this purpose, I'll use it in the meantime. The one change that I made was replace pre with code so that inline code would not be parsed either.

Im glad it works!

Im marking this issue as closed but believe me, I'll keep this in the back of my head for the next major release of this library!

Cheers!
