问题描述

解决方案

Mx ibuffer RET t U


$ b $但是你可能想要比这更有限制,因为如果它不能做一个替换,它会中止 - 例如遇到包含匹配文件名的只读dired缓冲区。



Ch m 在ibuffer中阅读模式帮助,并学习如何轻松地标记您感兴趣的缓冲区。



编辑:非正则表达式版本 ibuffer-do-replace-regexp 可以通过修改原始定义轻松地写入:

  ;;定义ibuffer-do-replace-string 
(define-ibuffer-op replace-string(from-str to-str)
在标记缓冲区中执行replace-string。
(:interactive
(let from(from-str(read-from-minibufferReplace string:))
(to-str(from-minibuffer
with:)))))
(从str到str的列表)
:opstring替换为
:complex t
: p:也许)
(save-window-excursion
(switch-to-buffer buf)
(save-excursion
(goto-char(point-min))
(let((case-fold-search ibuffer-case-fold-search))
(while(从-ni t搜索转发)
(替换匹配to-str nil t) )))
t))


How do I "M-x replace-string" across all buffers in emacs?

解决方案

M-x ibuffer RET t U

But you'll probably want to be a bit more restrictive than that, because it will abort if it can't do a replacement -- e.g. encounters a read-only dired buffer containing a matching filename.

C-hm within ibuffer to read the mode help, and learn how to easily mark just the buffers you're interested in.

Edit: a non-regexp version of ibuffer-do-replace-regexp can easily be written by modifying the original definition:

;; defines ibuffer-do-replace-string
(define-ibuffer-op replace-string (from-str to-str)
  "Perform a `replace-string' in marked buffers."
  (:interactive
   (let* ((from-str (read-from-minibuffer "Replace string: "))
          (to-str (read-from-minibuffer (concat "Replace " from-str
                                                " with: "))))
     (list from-str to-str))
   :opstring "replaced in"
   :complex t
   :modifier-p :maybe)
  (save-window-excursion
    (switch-to-buffer buf)
    (save-excursion
      (goto-char (point-min))
      (let ((case-fold-search ibuffer-case-fold-search))
        (while (search-forward from-str nil t)
          (replace-match to-str nil t))))
    t))
