[Insight-developers] Anyone got Emacs config for ITK-standard indentation?

[Mark Foskey]

Here's what I have.  I'm just pasting it in -- notice that it sets up 
two styles.  The t after "my-c-style" means that's my default.  If you 
want to keep it simple, it should be easy to see how to modify the 
my-c-style block with the entries from itk-c-style.

(setq my-c-style
       '((c-basic-offset . 4)
	(vip-autoindent . t)
         (c-electric-pound-behavior . 'alignleft)
	(c-comment-only-line-offset . 0)
	(c-offsets-alist . ((statement-block-intro . +)
			    (substatement-open . 0)
                             (inline-open . 0)
                             (innamespace . 0)
                            ; (brace-list-entry . +)
                            ; (brace-entry-open . 0)
                            ; (brace-list-close . 0)
			    (knr-argdecl-intro . 0)
			    (label . 0)
			    (statement-cont . c-lineup-math)
                             (innamespace . 0)))))
(setq itk-c-style
       '("myk&r"
         (c-basic-offset . 2)
	(c-offsets-alist . ((statement-block-intro . 0)
                             (substatement-open . +)))))

(add-hook 'c-mode-common-hook
	  (function (lambda ()
		      (c-add-style "myk&r" my-c-style t)
                       (c-add-style "itk" itk-c-style)
                       )))


The following code I find handy when editing people's code that uses 
different indentation widths than I do.  When I hit f9 I get a prompt 
to input a new value for the spacing.

(global-set-key [f9] 'my-set-c-space)

(defun my-set-c-space (n)
   (interactive "nSpacing: ")
   (setq c-basic-offset n))
