Emacs：在点处插入单词替换字符串查询

Question

Is there an analogue to inserting the word after point into the isearch query by hitting Cw after Cs but for the replace string (and replace regexp) queries?

I also enjoy Sacha Chua's modification of Cx inserting whole word around point into isearch:

This too would be really useful in some cases if it could be used in replace string.

I'd be very thankful for any tips! Thank you!

Answer 1

This will do it, although it isn't as fancy as Cw in isearch because you can't keep hitting that key to extend the selection:

(defun my-minibuffer-insert-word-at-point ()
  "Get word at point in original buffer and insert it to minibuffer."
  (interactive)
  (let (word beg)
    (with-current-buffer (window-buffer (minibuffer-selected-window))
      (save-excursion
        (skip-syntax-backward "w_")
        (setq beg (point))
        (skip-syntax-forward "w_")
        (setq word (buffer-substring-no-properties beg (point)))))
    (when word
      (insert word))))

(defun my-minibuffer-setup-hook ()
  (local-set-key (kbd "C-w") 'my-minibuffer-insert-word-at-point))

(add-hook 'minibuffer-setup-hook 'my-minibuffer-setup-hook)

EDIT: Note that this is in the standard minibuffer, so you can use it use it anywhere you have a minibuffer prompt, for example in grep, occur, etc.

Answer 2

我认为这已经存在于Emacs中了 - 你只需要用MS-%替换然后按下Mn （当迷你缓冲区为空时），这填写了光标下的单词，你可以用更多有用的东西，查看http： //endlessparentheses.com/predicting-the-future-with-the-mn-key.html?source=rss#disqus_thread 。

Answer 3

Two answers:

1. Replace+ automatically picks up text at point as the default value when you invoke replace commands.

2. More generally, Icicles does something similar to what scottfrazer's code (above) does, but it is more general. At any time, in any minibuffer, you can hit M-. (by default) to pick up text ("things") at point and insert it in the minibuffer. You can repeat this, to either (a) pick up successive things (eg words) of the same kind, accumulating them like Cw does for Isearch, or (b) pick up alternative, different things at point.
