assert_eq!(markdown_to_html("* [x] Done\n* [ ] Not done\n", &options),
           "<ul>\n<li><input type=\"checkbox\" checked=\"\" disabled=\"\" /> Done</li>\n\

           "<p>Hi<sup class=\"footnote-ref\"><a href=\"#fn-x\" id=\"fnref-x\" data-footnote-ref>1</a></sup>.</p>\n<section class=\"footnotes\" data-footnotes>\n<ol>\n<li id=\"fn-x\">\n<p>A greeting. <a href=\"#fnref-x\" class=\"footnote-backref\" data-footnote-backref data-footnote-backref-idx=\"1\" aria-label=\"Back to reference 1\">↩</a></p>\n</li>\n</ol>\n</section>\n");

let mut options = Options::default();
options.extension.front_matter_delimiter = Some("---".to_owned());
let arena = Arena::new();
let input ="---\nlayout: post\n---\nText\n";
