'C-q C-j' looks ugly in code

'C-q C-j' looks ugly in code

[Thorsten Jolitz]

Hi List, 

assume I write elisp code to replace occurences of "^J" in a string with
the actual line-feeds, i.e. with C-q C-j.

That works, but looks really ugly in the code:

#+begin_src emacs-lisp
(if A
    (if B
        (if C
            ;; deeply indented code
            (replace-string "^J" "
" nil beg end)
          (message "C"))
      (message "B"))
  (message "A"))
#+end_src

Is there a way to write C-q C-j in source code that does not actually
inserts the line-feeds?

cheers,

I'd use \n.

I just tested this in scratch, and it looks like (replace-string "^J" "\n")
works as expected...

Of course, I used "\n" so often, forgot that its just another way to
enter ^J ... well, thanks anyway.

You can also use "\^j" or "\C-j" or "\x0a" or "\012".
