Emacs changed indenting on me

Emacs changed indenting on me

[Sarir Khamsi]

Well, I have no idea what I did but GNU Emacs (21.3.50.1) changed
indenting of C++ code. Now it indents 2 spaces instead of the usual 3
and moves comment characters ("//") typed in the first column to align
with the indented code...it didn't do that before.

Any ideas on what I could have done to make this happen or how I can
fix it? (I'm on WinXP, SP1.) Thanks.

Try c-set-style

When prompted use ? to list available styles.  There are 11 under the 
W2000 install!.  I like Ellemtel.

Thanks, but does that change the indentation amount (ie, number of
spaces) and comment character placement? I don't see a call to that in
my ~/.emacs file.

Never mind...I did a diff between previous versions and found my
problem. Sorry.

You're supposed to tell us what the problem was so that we can all learn!

Yes it does.  It can completely change the indentation style including the
number of spaces.

If the spaces do not suit you you can change that by setting the
c-basic-offset variable.  For example, I like 5 spaces per indent:

(setq c-basic-offset 5)

In reality I use the stroustroup indentation style which uses a
basic-offset of 5 anyhow.

Fair enough...this is what I took out:

(add-hook 'c-mode-hook
 	  (function (lambda ()
  		      (setq c-file-style "local"))))

(add-hook 'c++-mode-hook
  	  (function (lambda ()
  		      (setq c-file-style "local"))))
(c-add-style "local"
'((c-basic-offset . 3)
  (c-comment-only-line-offset . 0)
  (c-hanging-braces-alist . ((substatement-open before after)))
  (c-offsets-alist . ((topmost-intro        . 0)
		      (topmost-intro-cont   . 0)
		      (substatement         . 3)
		      (substatement-open    . 0)
		      (statement-case-open  . 3)
		      (statement-cont       . 3)
		      (access-label         . -3)
		      (inclass              . 3)
		      (inline-open          . 0)
		      ))))

I didn't think I needed it. After I got the initial reply, it all made
sense when I did the diff.

I still think you would do better using something like this in your 
.emacs:

                             ;Set Ellemtel as the default indent style
                                      ;Stroustrup looks about the same
(add-hook 'c-mode-hook
          '(lambda ()
             (c-set-style "Ellemtel")))

There are several complete systems of C styles, which should be more 
satisfactory than re-inventing the wheel.  Of course, you may like 
inventing!
