Testing a fenced block without CODE tag: comments welcome

[jerry1970]

I already posted about this in the main Parsedown section, but it should be here...

I was looking for a fenced block with a DIV tag instead of the CODE tag. When writing articles for our CMS, I want people to have a little control over the outcome. Like a paragraph that is centered or right-aligned, or a piece of lyrics.

I used the period to fence the block and you can add one or more class names after it. So something like this:

    ... lyrics
    here are lyrics
    for a song
    ....

And it parses into this (two spaces after the first line of lyrics to make the BR):

    <div class="lyrics">
        <p>here are lyrics<br />
        for a song</p>
    </div>

Below are the function in the extension. Any suggestions or comments? Nested fenced blocks don't work (yet) - not sure if I need them...

    protected function blockWrap($Line)
    {
        if (preg_match('/^\.{3,}[ ]?(.*)/', $Line['text'], $matches)) {
            $Block = array(
                'element' => array(
                    'name' => 'div',
                    'handler' => 'lines',
                    'attributes' => ['class' => $matches[1]],
                ),
            );

            return $Block;
        }
    }

    protected function blockWrapContinue($Line, array $Block)
    {
        if (isset($Block['complete'])) {
            return;
        }

        if ($Line['text'][0] === '.' and preg_match('/^\.{3,}[ ]?(.*)/', $Line['text'], $matches)) {
            if (isset($Block['interrupted'])) {
                $Block['element']['text'] []= '';
                unset($Block['interrupted']);
            }

            $Block['element']['text'] []= $matches[1];
            $Block['complete'] = true;

            return $Block;
        }

        if ( ! isset($Block['interrupted'])) {
            $Block['element']['text'] []= $Line['text'];
            return $Block;
        }
        return $Block;
    }

    protected function blockWrapComplete($Block)
    {
        return $Block;
    }
