Simple emacs mode

I'm looking for a major mode for emacs that does absolutely nothing. No formatting, no indentation.

I want only the characters entered from the keyboard in the buffer without modification.

Is there such a mode?

Why?

I mean, it would probably be like this:

(defun noop-mode ()
  "Don't do anything."
  t)

(provide 'noop-mode)

But... why don't you just not load a mode then?

I think you're looking for fundamental-mode.

Sorry, but no. It has the problem that if a line is indented, pressing Enter at the end of that line puts the cursor on the next line indented.

I tried

;;;###autoload
(define-generic-mode null-mode
  nil nil nil nil nil
  "Do nothing.")

(provide 'null-mode)

It allowed me to select null-mode, but has the same problem.

It looks like I need to find where \n is configured when emacs is started.

Depending on which version of Emacs you're using, disabling electric-indentation-mode might help (M-- M-x electric-indentation-mode).

Otherwise, I guess you'll need to make a new mode with a different value for indent-line-function (the default is indent-relative):

(define-derived-mode no-indent-mode fundamental-mode "NoIndent" 
  (setq-local indent-line-function #'ignore))

Thanks.
Disabling electric-indent-mode works.

there never was anything simple about emacs

There actually was.

e3 now that is a simple editor and at 17KB (for the 64bit version)
it is small and it's easy to use
