自动包装I搜索？ [英] Automatically wrapping I-search?

问题描述

在Vim中，我可以：set wrapscan ，以便当我进行增量搜索时，光标会跳转到第一个匹配，无论第一个匹配是否高于或低于游标。

In Vim I can :set wrapscan so that when I do an incremental search, the cursor jumps to the first match whether the first match is above or below the cursor.

在Emacs中，如果我通过 Cs 开始搜索，则搜索失败，表示失败I-search 如果第一个匹配在光标上方。如果我再次点击 C-s ，那么它将包装搜索，称为<包裹I搜索。默认情况下，如Vim中所包含和跳转光标，而不必再次使用 Cs

In Emacs, if I start a search via C-s, the search fails saying Failing I-search if the first match is above the cursor. If I hit C-s again it then wraps the search, saying Wrapped I-search. How do I wrap and jump the cursor by default as in Vim, without having to C-s a second time?

推荐答案

最简单的方法是使用以下defadvice：

The easiest way to do this is to use the following defadvice:

(defadvice isearch-repeat (after isearch-no-fail activate)
  (unless isearch-success
    (ad-disable-advice 'isearch-repeat 'after 'isearch-no-fail)
    (ad-activate 'isearch-repeat)
    (isearch-repeat (if isearch-forward 'forward))
    (ad-enable-advice 'isearch-repeat 'after 'isearch-no-fail)
    (ad-activate 'isearch-repeat)))

当Isearch失败时，它立即重新包装。请注意，暂时禁用此defadvice以防止无匹配时无限循环非常重要。

When Isearch fails, it immediately tries again with wrapping. Note that it is important to temporarily disable this defadvice to prevent an infinite loop when there are no matches.
