在dired中查找并替换没有正则表达式

Question

我正在尝试将网站转换为电子书,并且在每个页面的开头都有大量的html我要删除.正如您可以想象的那样,Q由于大块中的某些内容未正确转义,因此使用不匹配的结果.当我尝试解决问题时,我得到堆栈溢出.

我真正需要的是一种在没有正则表达式的情况下以正常的M-%方式查找和替换dired的方法.这可能吗？

Answer 1

正则表达式中的正则表达式行为是可选的,但该函数在一些地方调用硬编码假设.我认为最简单的解决方案是制作在运行时不设置正则表达式标志的副本.

(eval-after-load 'dired
  '(define-key dired-mode-map (kbd "C-c Q") 'my-dired-do-query-replace))

(defun my-dired-do-query-replace (from to &optional delimited)
  "Do `query-replace' of FROM with TO, on all marked files.
Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
If you exit (\\[keyboard-quit], RET or q), you can resume the query replace
with the command \\[tags-loop-continue]."
  (interactive
   (let ((common
          (query-replace-read-args
           "Query replace in marked files" nil t)))
     (list (nth 0 common) (nth 1 common) (nth 2 common))))
  (require 'dired-aux)
  (dolist (file (dired-get-marked-files nil nil 'dired-nondirectory-p))
    (let ((buffer (get-file-buffer file)))
      (if (and buffer (with-current-buffer buffer
                        buffer-read-only))
          (error "File `%s' is visited read-only" file))))
  (my-tags-query-replace
   from to delimited '(dired-get-marked-files nil nil 'dired-nondirectory-p)))

(defun my-tags-query-replace (from to &optional delimited file-list-form)
  "Do `query-replace' of FROM with TO on all files listed in tags table.
Third arg DELIMITED (prefix arg) means replace only word-delimited matches.
If you exit (\\[keyboard-quit], RET or q), you can resume the query replace
with the command \\[tags-loop-continue].
Fourth arg FILE-LIST-FORM non-nil means initialize the replacement loop.
Fifth and sixth arguments START and END are accepted, for compatibility
with `query-replace', and ignored.

If FILE-LIST-FORM is non-nil, it is a form to evaluate to
produce the list of files to search.

See also the documentation of the variable `tags-file-name'."
  (interactive (query-replace-read-args "Tags query replace" nil t))
  (require 'etags)
  (setq tags-loop-scan `(let ,(unless (equal from (downcase from))
                                '((case-fold-search nil)))
                          (if (search-forward ',from nil t)
                              ;; When we find a match, move back
                              ;; to the beginning of it so perform-replace
                              ;; will see it.
                              (goto-char (match-beginning 0))))
