Emacs: Suppressing auto indentation for C source files

Emacs: Suppressing auto indentation for C source files

[Generic Usenet Account]

My apologies if this posting is off topic.

I want to suppress the auto indentation for C source files in my emacs
editor (GNU Emacs 21.2.1, XEmacs 21.4).  I have added the following two
lines in my .emacs file, but that does not seem to help:

(setq indent-tabs-mode nil)
(setq c-indent-line nil)

Any suggestions?

Thanks,
Gus

I have this in my .emacs to set up things for c-mode:


(defun my-c-mode-common-hook ()
  (c-set-style "user")
  (c-set-offset 'case-label '+)
  (c-set-offset 'substatement-open 0)
  (setq fill-column 75)
  (imenu-add-menubar-index)
  (add-hook 'c-mode-hook 'turn-on-cwarn-mode)
  (add-hook 'c-mode-hook
	    (lambda ()
	      (set (make-local-variable 'ispell-skip-region-alist)
		   (cons '("\\\\[abfnrtv\\'\"]") ispell-skip-region-alist))))
  )
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)


You need something like this, modified to hold the values you want to set...

None needed.  The posting is bang on topic.

The term "auto indentation" covers several aspects in CC Mode.
(i) There's the indentation which happens when you type <TAB> or C-j.
(ii) There's the "electric indentation" which happens when you type a
semicolon or parenthesis or ....

In the current versions of CC Mode (5.28 or 5.30.n:  use M-x c-version to
see which one you've got), there isn't much control you can exercise over
these.  In the soon-to-be-released CC Mode 5.31, you can independently
disable the "electric indentation".

`c-indent-line' doesn't exist.  `indent-tabs-mode' merely says whether
you want to use (mainly) tabs to indent with or only spaces.

Try (setq c-syntactic-indentation nil).  If you still want to be able to
indent with <TAB> or C-j, wait for CC Mode 5.31, which will be available
on <http://www.sourceforge.net/release.php> some time "soon".

Auto indentation?  What do you mean?  You type

if (foo) {

and when you hit newline, the cursor's indented?
