marked-denden is a Marked extension to enable the DenDenMarkdown syntax to be used in Marked.js.

Currently only ruby, Horizontal-in-Vertical Text Composition and EPUB pagebreak syntax, Footnote are supported.

import { marked } from "marked";
import markedFootnote from 'marked-footnote';
import dendenMarkdown from "marked-denden";

// or UMD script
// <script  src="https://cdn.jsdelivr.net/npm/marked/lib/marked.umd.js"></script>
// <script  src="https://cdn.jsdelivr.net/npm/marked-footnote/dist/index.umd.min.js"></script>
// <script  src="https://cdn.jsdelivr.net/gh/otodn/marked-denden/src/index.umd.min.js"></script>

const dendenOptions = { 
    rubyParenthesisOpen: "",
    rubyParenthesisClose: "",
    autoTcy: true,
    tcyDigit: 2,
    autoTextOrientation: true,
    epubType: true,
    dpubRole: true,
  }

// Setting DenDenMarkdown and outputs closer together.
marked.setOptions({
    gfm: true,
    breaks: true,
  });

// This extension overrides the footnote extension and should not change the order.
marked.use(markedFootnote())
marked.use(dendenMarkdown(default_options));

// OR
// marked.use(markedFootnote(),dendenMarkdown(dendenOptions));

marked.parse("{電子出版|でんししゅっぱん}を手軽に");
// <p><ruby>電子出版<rt>でんししゅっぱん</rt></ruby>を手軽に</p>

marked.parse("^ABC^ 2月29日!? ★≠☆");
// <p><span class="tcy">ABC</span> 2月<span class="tcy">29</span>日<span class="tcy">!?</span> <span class="upright">★</span><span class="sideways">≠</span><span class="upright">☆</span></p>
