<p>1ヵ月弱使いましたがこの<a href="https://docusaurus.io/" target="_blank" rel="noopener noreferrer">Docusaurus</a>（ドキュサウルス）は数あるCMSの中でも秀逸です。</p>
<p>文書作成と管理が容易で、拡張の自由度も非常に高く、完全なオープンソース。</p>
<p>議員活動に重要な「<strong>資料を作成しまとめて公開するツール</strong>」として現状の最適解と感じます。</p>
<!-- -->
<p>Facebookが母体なのでいろいろと気になるところですが、<a href="https://ja.legacy.reactjs.org/" target="_blank" rel="noopener noreferrer">React</a>を初めとして有益なソフトウェアを完全なオープンソースとして提供してくれていることは純粋にありがたいと感じます。</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="admonitionのタイトルが見出しにならない">Admonitionのタイトルが見出しにならない<a href="#admonitionのタイトルが見出しにならない" class="hash-link" aria-label="Admonitionのタイトルが見出しにならない への直接リンク" title="Admonitionのタイトルが見出しにならない への直接リンク"></a></h2>
<p>さてDocusaurusには<a href="https://docusaurus.io/docs/markdown-features/admonitions" target="_blank" rel="noopener noreferrer">Admonition</a>（注意書きや警告文）を容易にMarkdownで書く方法が用意されています。</p>
<p>たとえばinfoなら、次のようにMarkdownで書けば、</p>
<div class="language-mdx codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#393A34;--prism-background-color:#f6f8fa"><div class="codeBlockTitle_Ktv7">Admonitionの記法（mdもしくはmdxに記載）</div><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-mdx codeBlock_bY9V thin-scrollbar" style="color:#393A34;background-color:#f6f8fa"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#393A34"><span class="token plain">:::info[infoの例]</span><br></span><span class="token-line" style="color:#393A34"><span class="token plain" style="display:inline-block"></span><br></span><span class="token-line" style="color:#393A34"><span class="token plain">ここに文章を書く</span><br></span><span class="token-line" style="color:#393A34"><span class="token plain" style="display:inline-block"></span><br></span><span class="token-line" style="color:#393A34"><span class="token plain">:::</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="クリップボードにコードをコピー" title="コピー" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg viewBox="0 0 24 24" class="copyButtonIcon_y97N"><path fill="currentColor" d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg viewBox="0 0 24 24" class="copyButtonSuccessIcon_LjdS"><path fill="currentColor" d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div>
<p>次のようにHTMLで表示されます。</p>
<div class="theme-admonition theme-admonition-info admonition_Gfwi alert alert--info"><div class="admonitionHeading_f1Ed"><span class="admonitionIcon_kpSf"><svg viewBox="0 0 14 16"><path fill-rule="evenodd" d="M7 2.3c3.14 0 5.7 2.56 5.7 5.7s-2.56 5.7-5.7 5.7A5.71 5.71 0 0 1 1.3 8c0-3.14 2.56-5.7 5.7-5.7zM7 1C3.14 1 0 4.14 0 8s3.14 7 7 7 7-3.14 7-7-3.14-7-7-7zm1 3H6v5h2V4zm0 6H6v2h2v-2z"></path></svg></span>infoの例</div><div class="admonitionContent_UjKb"><p>ここに文章を書く</p></div></div>
<p>しかし（DocusaurusV3.1）でこのAdmonitionのタイトルは見出し（<a href="https://docusaurus.io/docs/markdown-features/toc" target="_blank" rel="noopener noreferrer">Heading</a>）にならず、目次（<a href="https://docusaurus.io/docs/markdown-features/toc" target="_blank" rel="noopener noreferrer">TOC</a>）にも乗りません。上記例なら「INFOの例」がTOCに表示されません。</p>
<p>次の図からも分かっていただけるかと思います。</p>
<p><img decoding="async" loading="lazy" alt="Admonitionのタイトルが見出しにならない" src="/docs/assets/images/admonition-no-toc-98d7dfb77b6d769fe6815f0fb702575d.png" width="903" height="820" class="img_ev3q"></p>
<p>些細なことのようにも思えますが、Docusaurusを書籍のように扱うには結構気になるところ。</p>
<p>なお<a href="https://github.com/elviswolcott/remark-admonitions/issues/26" target="_blank" rel="noopener noreferrer">以前はAdmonitionのタイトルはH5要素になっていた</a>ようですが、深さ（H1～H5のレベル）を決め打ちするのは好ましくないということから（？）、今はH5要素ではありません。</p>
<p>次のように本文中に見出しを書く方法もありますが</p>

<p>RemarkとRehypeは、MarkdownをHTMLに変換するプロセスにおいて、AST（抽象構文木・Abstract Syntax Tree）に作用するプラグインです。なお<a href="https://github.com/unifiedjs/unified" target="_blank" rel="noopener noreferrer">ASTを操作するオープンソースのエコシステム</a>の中にはもう１つ<a href="https://github.com/retextjs/retext" target="_blank" rel="noopener noreferrer">Retext</a>というプラグインもありますが、Docusaurusには実装されていないようです。</p>

<p>上図（<a href="https://github.com/unifiedjs/unified?tab=readme-ov-file#overview" target="_blank" rel="noopener noreferrer">Unified Overviewより</a>）にTransformersとあるところがRemark/Rehypeの動作するところ。</p>
<p>RemarkはMarkdown形式で、RehypeはHTML形式でASTを扱います。どちらも同じようにASTを操作できますが、データ構造が違うため、目的に応じて選択することになるのかなと思います。</p>
<p><a href="https://vivliostyle.github.io/vivliostyle_doc/ja/vivliostyle-user-group-vol2/spring-raining/index.html" target="_blank" rel="noopener noreferrer">こちらのサイト</a>などが詳しいです。</p>
<h4 class="anchor anchorWithStickyNavbar_LWe7" id="docusaurusにおけるプラグインの実行タイミング">Docusaurusにおけるプラグインの実行タイミング<a href="#docusaurusにおけるプラグインの実行タイミング" class="hash-link" aria-label="Docusaurusにおけるプラグインの実行タイミング への直接リンク" title="Docusaurusにおけるプラグインの実行タイミング への直接リンク"></a></h4>
<p>Docusaurusでこれらのプラグインを利用するためにはdocusaurus.config.jsonに設定が必要です。<a href="https://docusaurus.io/docs/markdown-features/plugins" target="_blank" rel="noopener noreferrer">このページによると</a>次の4種類の設定値にてプラグインを登録できます。</p>
<table><thead><tr><th></th><th>デフォルトプラグイン適用前</th><th>デフォルトプラグイン適用後</th></tr></thead><tbody><tr><td>Remark<br>Markdown形式</td><td>beforeDefaultRemarkPlugins</td><td>remarkPlugins</td></tr><tr><td>Rehype<br>HTML形式</td><td>beforeDefaultRehypePlugins</td><td>rehypePlugins</td></tr></tbody></table>
<p>MarkdownからHTMLへの変換処理のところで、Docusaurusは自前のプラグイン（デフォルトプラグイン）を使い「見出しにidをつける」「ASTからTOCを作成する」などの処理を行っています。そのため今回のように「Amonitionのタイトルを読んでTOCに反映する」ためには、デフォルトプラグイン適用前と適用後の両方のタイミングでの処理が必要になります。</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id="swizzlingについて">Swizzlingについて<a href="#swizzlingについて" class="hash-link" aria-label="Swizzlingについて への直接リンク" title="Swizzlingについて への直接リンク"></a></h3>
<p>Swizzlingは<a href="https://docusaurus.io/docs/swizzling" target="_blank" rel="noopener noreferrer">こちら</a>に説明があるとおりの機能で、簡単に言うとReactのコンポーネントをカスタマイズできる機能です。</p>
<p>Swizzlingの設定をすると、Docusaurusがデフォルトのコンポーネントの代わりに自動的にカスタマイズしたコンポーネントを使用します。</p>
<p>今回は、デフォルトのAdmonitionにないID属性を持たせるためAdmonitionコンポーネントをカスタマイズしました。Swizzlingの設定をすることにより、デフォルトのAdmonitionの代わりにこのカスタムコンポーネントが使われるようにします。</p>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="動作原理">動作原理<a href="#動作原理" class="hash-link" aria-label="動作原理 への直接リンク" title="動作原理 への直接リンク"></a></h2>
<p>TOCは「ASTに含まれているheading要素を単純に配列に入れている」だけですが、この処理はカスタマイズで上書きできません。そこで、カスタマイズできる処理だけでAdmonitionのタイトルをTOCに反映する方法として次を思いつき、実装しました。</p>
<ol>
<li>docusaurusのデフォルトプラグインがTOCの処理を行うより前に、Admonitionのタイトル部を見出しとして新規作成し、Admonition要素の直前に追加する</li>
<li>docusaurusのデフォルトプラグインがTOCの処理を行い、Admonitionのタイトル部がTOCに入る。見出しにはidが付与される</li>
<li>デフォルトプラグインの処理が終了したら作成した見出しは不要になるので削除する。その際、削除する見出しと同じタイトルをもつAdmonition要素を探し、idを与える</li>
<li>AdmonitionコンポーネントでidをHTMLタグに付与する</li>
</ol>
<h2 class="anchor anchorWithStickyNavbar_LWe7" id="実装">実装<a href="#実装" class="hash-link" aria-label="実装 への直接リンク" title="実装 への直接リンク"></a></h2>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id="docusaurusconfigjson">docusaurus.config.json<a href="#docusaurusconfigjson" class="hash-link" aria-label="docusaurus.config.json への直接リンク" title="docusaurus.config.json への直接リンク"></a></h3>
<p>まずdocusaurus.config.jsonにimportとplugin設定を記入します（ハイライト部）。</p>
<p>これでDocusaurusデフォルトプラグイン適用の前後にそれぞれ自作のRemark/Rehypeプラグインが実行されることになります。</p>
<p>blogなどを入れている場合は、そのプロパティにも記載します。</p>

<p>次にSwizzlingです。</p>
<p>Docusaurusのsrc/themeディレクトリにAdmonitionというディレクトリを作り、次の一例のファイルを格納します。</p>
<p>なお<a href="https://docusaurus.io/docs/swizzling#ejecting" target="_blank" rel="noopener noreferrer">ここに説明がある通り</a>SwizzlingにはEjectingとWrappingの方法があります。</p>
<p>WrappingではAdmonitionの内部までカスタマイズできないため「タイトル部分にidプロパティを付ける」といったことができません。そのためEjectingを使います。</p>
