変更内容

1. Pagefind による全文検索

  • ヘッダー右上に虫眼鏡アイコン(クリックでモーダル検索)
  • <html lang> による en/ja のインデックス自動分離
  • マッチ語は太字ハイライト
  • CI で jekyll build 後に npx pagefind --site _site を実行

2. モバイル対応

  • 検索トリガーを全ブレークポイントで表示(md 未満でも検索可能)
  • En/Ja 切替はデスクトップのみ(モバイルはサイドバーに既存の切替があるため重複回避)
  • モバイルでは align-self-end で右寄せ、md 以上では align-self-md-auto で従来通り

3. 1page.md の廃止

  • merge_md_files.rb と生成済み 1page.md(en/ja 計 4,666行)を削除
  • ナビゲーションの「1 Page」リンクを削除

4. ローカル開発

  • serve_local.sh がビルド後に Pagefind インデックスを一度生成
  • keep_files に pagefind を追加し watch 再ビルドでも消えないように

検証済み

  • Jekyll ビルド成功、1page.html が生成されないことを確認
  • Pagefind が 2言語・104ページ をインデックス
  • モバイル(390x844): トリガー表示・右寄せ、横スクロールなし、全画面モーダルで検索動作
  • デスクトップ(1280px): トリガーと En/Ja の垂直位置一致(中央 29px)

Summary by CodeRabbit

  • New Features

    • Added search functionality to English and Japanese manual pages.
    • Added site-wide search indexing during local builds and deployments.
  • Documentation

    • Removed the consolidated “1 Page” manual links and pages.
    • Manual content is now accessed through individual documentation pages.
  • Style

    • Updated mobile manual navigation and language selector behavior.
    • Added responsive styling for the search control.

- Add client-side search via Pagefind Component UI (modal)
  - Magnifier icon trigger in manual page header
  - Auto language separation (en/ja) via <html lang>
- Remove 1page.md generation (merge_md_files.rb and generated files)
- Update CI to generate Pagefind index after Jekyll build
- Add pagefind to keep_files for watch mode stability
The search trigger was hidden below the md breakpoint (d-none d-md-flex),
leaving small screens with no way to search.

- Show the trigger row on all breakpoints; keep the En/Ja switcher
desktop-only since small screens already have one in the sidebar nav
- Right-align the trigger on small screens with align-self-end, which is
reset to auto above md so the desktop layout is unchanged

📝 Walkthrough

Walkthrough

The site now builds Pagefind indexes for documentation content and loads a Pagefind search interface in manual pages. The change also removes aggregated 1.0 manual pages, their navigation links, and the script that generated them.

Changes

Pagefind indexing and manual search

Layer / File(s) Summary
Search index generation
.github/workflows/jekyll.yml, _config.yml, _layouts/docs-en.html, _layouts/docs-ja.html, bin/serve_local.sh
The CI workflow and local server generate Pagefind indexes. Jekyll preserves the pagefind directory. Documentation articles are marked for indexing.
Manual search interface
_includes/manuals/1.0/header.html, _includes/manuals/1.0/en/contents.html, _includes/manuals/1.0/ja/contents.html, css/manual-skeleton.css
Manual pages load Pagefind assets and provide a search modal trigger. CSS displays the trigger as an icon and updates the responsive navigation layout.
Aggregated manual removal
_includes/manuals/1.0/en/contents.html, _includes/manuals/1.0/ja/contents.html, bin/merge_md_files.rb, manuals/1.0/en/1page.md, manuals/1.0/ja/1page.md
The one-page navigation entries, aggregate manual files, and manual merge script are removed.

Remove the deleted script invocation.

The PR removes bin/merge_md_files.rb, but this job still invokes it. The step will fail before Jekyll builds or Pagefind generates the index. Remove this command from Run custom scripts.

The trigger sat below the nav links on its own row, which read as misaligned.
Place it in the sidebar navigation header instead, next to the language
switcher, and flip that row to hamburger-left / search+language-right.

- contents.html (en/ja): flex the mobile header row, add the trigger, and
  move the toggler first so it renders on the left
- header.html: drop the mobile-only item from the nav link list
- css: space the trigger from the language switcher, nudge the magnifier down
  2px (its handle sits low-right, so the glyph reads high), and reset the
  toggler's inherited margin-left:auto / set order so it sits left
This branch drops 1page.md generation, but several workflows still called
bin/merge_md_files.rb or asserted that 1page.md existed, so the validate job
failed with "No such file or directory -- bin/merge_md_files.rb".

- jekyll.yml / documentation.yml / validate-documentation.yml: drop the
  single-page generation, validation and copy steps
- update-documentation.yml: removed entirely. Its only purpose was to
  regenerate and commit 1page.md (llms-full.txt is git-ignored), so with
  1page gone the workflow has nothing left to do.
