Emacs：组合iseach前进和最上层 [英] Emacs: Combine iseach-forward and recenter-top-bottom

问题描述

非常感谢您的帮助。

在Emacs中，我喜欢使用iseach-forward（Cs），但是如果突出显示的浮动字将集中在屏幕中间而不是底部。

In Emacs, I like to use iseach-forward (C-s) but I'd like it ever more if the highlighted fount words would be centered in the middle of the screen instead of at the very bottom.

我发现自己在不断地这样做：

I find myself doing this continuously:

Cs foo
Cs Cs Cs ...
哦！这是我正在寻找的'foo'！
Cl

C-s foo C-s C-s C-s... oh! that's the 'foo' I was looking for! C-l

有没有办法将屏幕中央的搜索结果居中？

Is there a way to center the search results in the middle of the screen?

cheers

推荐答案

最佳方法可能是添加以下钩子：

Best approach would probably be to add the following hook:

(add-hook 'isearch-mode-end-hook 'recenter-top-bottom)

在每次成功的增量搜索完成后，将执行 recenter-top-bottom 命令。

This will execute the recenter-top-bottom command at the completion of every successful incremental search.

编辑：我已经调查了一点，并且重复搜索相同字符串执行的功能（即连续输入 Cs 或 Cr 在活动搜索期间）似乎是 isearch-repeat-forward 和/或 ISEARCH重复向后。因此，如果您希望在每次重复的同时，您还需要建议所述功能，除了定义上述钩子，如下所示：

I've investigated a bit, and the functions that are executed on repeated searches for the same string (i.e., with successive input of C-s or C-r during an active search) appear to be isearch-repeat-forward and/or isearch-repeat-backward. Hence, if you wish to recenter on every repeat as well, you need to advise said functions in addition to defining the above hook, like so:

(defadvice
  isearch-repeat-forward
  (after isearch-repeat-forward-recenter activate)
  (recenter-top-bottom))

(defadvice
  isearch-repeat-backward
  (after isearch-repeat-backward-recenter activate)
  (recenter-top-bottom))

(ad-activate 'isearch-repeat-forward)
(ad-activate 'isearch-repeat-backward)

isearch-mode-end-hook 中使用 recenter-top-bottom 并使用 recenter 单独对重复函数的建议将不那么讨厌。

Personally, I find the resulting behavior to be extremely annoying and disorienting, but de gustibus non est disputandum. Perhaps reserving recenter-top-bottom for use in the initial isearch-mode-end-hook and using recenter alone in the advice to the repeat functions would be less obnoxious.

建议 isearch-forward 本身等同于添加我以前建议的钩子，似乎对重复搜索没有影响。添加钩子比较简单，我认为更惯用，所以应该比建议这个功能更好。

Advising isearch-forward by itself is equivalent to adding the hook I originally suggested above and seemingly has no effect on repeat searches. Adding the hook is simpler and I think more idiomatic, so it should probably be preferred over advising the function.
