This method seems to be duplicated in your project.

	{
		$line = ltrim($lines[$current]);
		$fence = substr($line, 0, $pos = strrpos($line, $line[0]) + 1);
		$language = rtrim(substr($line, $pos));
		// consume until end fence
		$content = [];
		for ($i = $current + 1, $count = count($lines); $i < $count; $i++) {
			if (($pos = strpos($line = $lines[$i], $fence)) === false || $pos > 3) {
				$content[] = $line;
			} else {
				break;
			}
		}
		$block = [
			'code',
			'content' => implode("\n", $content),
		];
		if (!empty($language)) {
			$block['language'] = $language;
