Do not render the TOC if it is empty

[tomzx]

I have a blog where I force the TOC to render since the [TOC] macro is not part of the article's content.

{{ ('<p>[TOC]</p>'~page.content)|toc }}

However, I'd like it if the TOC didn't render anything if the table was empty. Is there any way to make that possible?

Thanks!

HI @tomzx , I guess that's something I have to update. Instead of L251 you may try this (untested).

$toc = $this->createToc($content);
// Don't process TOC if there aren't any headings in the content
if (empty($toc)) {
  return $content;
}

@Sommerregen Thanks!
