(defun my-find-orgfiles ()
  (interactive)
  (find-name-dired "." "*py"))

(global-set-key (kbd "M-n") 'my-find-orgfiles)

Than, t to toggle marked/unmarked files (thus marking them all, since none were marked). Then I use Q to use query-replace on the marked files. And enter .value to replace with value.

=> What am I trying to do? Replace a string that is starting or ending with . (dot) such as: .value or value..

=> What happens instead? During replacement Emacs also finds text such as (value, [space]value, [value and so on. In other words, .value is matching any character followed by value.

=> How can I force dired-do-find-regexp-and-replace (bound to Q in Dired buffers) to look for a literal . during string replacement?

  • After use of `M-n`, I press `t` and `Q`. Afterwards `Query replace regexp in marked files` pops up and I type `.value` goal is to replace it with `value`. So basically on the selected files I want to replace `.value` with`value` – alper Apr 23 '20 at 17:20

    Ah, so you use `t` to toggle marked/unmarked files (thus marking them all, since none were marked). Then you use `Q` to use query-replace on the marked files. You might want to add that info to the question, for clarity. – Drew Apr 23 '20 at 19:01

This really has nothing to do with find-name-dired.

This is about Q in Dired buffers (including from find-name-dired).

Q is dired-do-find-regexp-and-replace. That command treats your first input pattern as a regexp. And . in a regexp matches any character except newline.

What you want to use, instead of .value, is [.]value. That is, you want a pattern that matches only a . character.

  • This also occurs for words ending with `.` right? – alper Apr 23 '20 at 19:11

    It has nothing to do with words, per se. In a regexp, the character `.` matches any character other than a newline char. So yes, if you're asking about, say, `value.`, then that would match `value?`, `value)`, `value[`, `valueX`, `values`, etc. – Drew Apr 23 '20 at 20:18
