[pmwiki-users] custom sourceblock markup

[Alexandre Leray]

Thanks a lot Peter!

here is the recipe for those interested (I did not include the class arg
yet):

// Creates a code block marker
Markup("highlight", ">markupend",
"/\\(:highlight:\\)\\n(.*?)\\(:highlightend:\\)/es", "do_highlight('$1')");

function do_highlight($content) {
    $new_content = '<pre><code>';
    $new_content .= Keep(PSS($content));
    $new_content .= '</code></pre>';
    return $new_content;
}

I'm not sure about the ">markupend" argument, but it seems to work so
far. Note the PSS() function call in do_highlight(); It is used to
"removes the backslashes that are automatically inserted in front of
quotation marks by the /e option of PHP's preg_replace function"[^1].

Kind regards,
