Unusual C indentation conventions

Unusual C indentation conventions

[no spam]

hi, I've spent a fair amount of time trying to get emacs to do something 
reasonably close to what's required in my installation, and I find that 
it usually doesn't and I can't figure out why.  I'll manually space the 
bracket { to be where I want it, and then as soon as I start typing, 
it'll re-indent it, and even the .emacs variables that I would have 
thought would just turn off ALL syntax-directed indentation don't seem 
to do it.

All complaining aside, though:  what can I put in my .emacs to cause it 
to do this:

===================

The code follows an indentation convention that is a bit
unusual for C.  Opening and closing braces are on
a line by themselves and are indented at the same
level as the block they enclose:
     if (someTest)
         {
         doSomething();
         doSomethingElse();
         }
Tab stops are set to 8.  Each block of code is
indented by 4 from the previous block.  (In the
vi editor set ts=8  set sw=4)

=================

??


Thanks in advance.

The coding style whitesmith is close.  C-c . to run c-set-style.  Choose 
whitesmith.  You can change the indenting amount in cc-mode by doing M-x 
set-variable and set c-basic-offset to the number of spaces you desire.

You can change the tab stop width using the tab-width variable.  M-x 
set-variable again.

In your .emacs you might want something like the following to make 
everything happen automatically:


(add-hook c-mode
	(lambda ()
		(c-set-style "whitesmith")
		(setq c-basic-offset 4)
		(setq tab-width 8)))

Good luck!

Try this.. you'll probably want to modify the tabs.


(setq indent-tabs-mode nil
      tab-always-indent nil
      tab-stop-list '(4 8 12 16 20 24 28 32 36 40 44 48 52 56 60)
      tab-width 4)

(defun my-c-mode-common-hook ()
  (turn-on-font-lock)
  (setq c-tab-always-indent nil)
  (c-set-offset 'substatement-open 0)
  (c-set-offset 'arglist-intro 1)
  (c-set-offset 'defun-open 4)
  (c-set-offset 'defun-block-intro 0)
  (c-set-offset 'statement 0)
  (c-set-offset 'substatement-open 4)
  (c-set-offset 'statement-block-intro 0)
  (c-set-offset 'substatement 4)
  (c-set-offset 'statement-cont 4)
  (c-set-offset 'label -4)
  (c-set-offset 'topmost-intro-cont 4)
  (c-set-offset 'brace-list-intro 0)
  (c-set-offset 'class-open 4)
  (c-set-offset 'class-close 4)
  (c-set-offset 'topmost-intro '-)
  (c-set-offset 'brace-list-open 4)
  (c-set-offset 'access-label '--)
  (c-set-offset 'func-decl-cont 0)
  (c-set-offset 'case-label 0)
  (c-set-offset 'statement-case-intro 4)
  (c-set-offset 'statement-case-open 4)
  (c-set-offset 'inline-open '+))

(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)

This is a recognized problem, and the next version of CC Mode (5.31) will
enable users to disable "electric indentation", though the precise
details of this haven't quite been finalized.

(setq c-syntactic-indentation nil) should do it.  Have you tried that?

Please do complain!  If nobody complained about the things which annoy
them, nothing would get fixed.  ;-)
