Disabling Electric C Characters?

Disabling Electric C Characters?

[zenlikethat]

Hey guys, I'm having some trouble disabling electric characters in C mode in
my version of Emacs on Ubuntu.

Every time I type in a curly brace to close off a block of code like a
function or an if statement, the "}" reindents, completely disregarding
wherever I may have put it.  I don't like this and am trying my hardest to
turn it off, but nothing seems to work.

I've tried putting

(setq-default c-electric-flag nil) and
(setq-default c-syntactic-indentation nil)

in my .emacs file, but to no avail.

Any suggestions?

Thanks,

Nathan

OK, first things first - Have you got a recent enough version of CC
Mode?  The rest of your post suggests you have, but just to make
sure....  Do M-x c-version.  You need 5.31 or higher.  This version of
CC Mode only became part of GNU Emacs at version emacs-22.1.  If
necessary, you can download the current version (5.31.4) from
<http://cc-mode.sourceforge.net/release.php>.

OK.  The thinking behind this feature is that the indentation of a line
can often be calculated only _after_ the line's been typed, not before.
So things like "}" and ";" trigger reindentation.  I'd recommend you to
get to like this if you can.  :-)  However, let's accept that you can't
or won't.

Does C-c C-l (`c-toggle-electric-state') work?

(setq-default c-electric-flag nil) should work.  There may be a bug in
CC Mode here.

One other thing to try would be disabling the electricity in a hook.
Try this in your .emacs:

(defun zlt-disable-electricity ()
  (c-toggle-electric-state -1))
(add-hook 'c-mode-common-hook 'zlt-disable-electricity)
