I have HELLOWORLD string inside my file.


My setup:

(defun my-find-orgfiles ()
  (interactive)
  (setq toggle-case-fold-search 0)  ; Turn Off Smart Case Sensitivity
  (find-name-dired "~/folder" "*py"))

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

(add-hook 'python-mode-hook
          (lambda ()
            (setq flycheck-python-pylint-executable "~/venv/bin/pylint")
            (setq flycheck-pylintrc "~/.pylintrc")))
(setq case-fold-search nil)

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 helloword to replace with hello.


On the minibuffer I face with following:

Query replacing helloworld with HELLO: (? for help)

Than replaces HELLOWORLD into HELLO.

  • Here if replacement occurs I want it to replace into hello rather than HELLO, since I enter lower case hello

  • Since lower case helloword does not exist in the file, it shouldn't attempt to replace anything.


Note: Adding (setq case-fold-search nil) did not help.

Do M-x toggle-case-fold-search (message is Case-Insensitive Search disabled globally) before Q.

toggle-case-fold-search isn't a standard variable but rather a function. Perhaps you wanted to set buffer-local variable case-fold-search in my-find-orgfiles? Or maybe to call toggle-case-fold-search?

  • Can I set it in .emacs file?

  • Yes, you can (setq case-fold-search nil) in your .emacs/.init.el

    Because it's a buffer-local variable, you'll may want (setq-default case-fold-search nil)
