emacsでインクリメンタルサーチを使用すると、完全一致のどこにいるかわかりません。Chromeブラウザでは、「2of30」を使用して場所を表示します。どうすればEmacsでそれを行うことができますか?

これを実装する最初の試みです。
実装するレイジーハイライトを使用し、ハイisearch
ライトがバッファ全体(表示部分だけでなく)をカバーするように強制します。これにより、大きなバッファでの検索が遅くなる可能性があります。次に、表示を更新して、強調表示された検索結果に対する(合計の)現在の位置を含めます。
これには、検索および強調表示されるバッファ全体に依存するという欠点があります。また、C-s次の試合に進むと、(0 of 1)
ハイライトがはっきりと表示されていても、表示がに変わることがあります。
しかし、それは合理的な最初のカットのようです。
ビッグカット/ペーストの準備:

私は先日これを見ました:
https://github.com/syohex/emacs-anzu
anzu.elはanzu.vimのEmacsポートです。anzu.elは、さまざまな検索モードのモード行に現在の一致および合計一致情報を表示するマイナーモードを提供します。
githubページのスクリーンショットは、その機能のgifアニメーションです。
箱からM-so出して、isearching中に使用して、少なくとも一致の総数を確認できます(残念ながら、元のバッファーで実行している一致を追跡するのに十分なほど賢くない場合でも)。
以下をemacsinitファイルに追加します。カウントマッチを使用しているにもかかわらず、私のラップトップでは非常に高速に動作します。非常に大きなファイルでは試していません。
(defun my-isearch-update-post-hook()
(let (suffix num-before num-after num-total)
(setq num-before (count-matches isearch-string (point-min) (point)))
(setq num-after (count-matches isearch-string (point) (point-max)))
(setq num-total (+ num-before num-after))
(setq suffix (if (= num-total 0)
""
(format " [%d of %d]" num-before num-total)))
(setq isearch-message-suffix-add suffix)
(isearch-message)))
(add-hook 'isearch-update-post-hook 'my-isearch-update-post-hook)
