cc-mode case label brace indentation

cc-mode case label brace indentation

[David Spain]

I would like to go from this form of indentation of
braces within a case labe in cc-mode:

   switch (arg) {
       case 0:
       {
           item1;
           item2;
           item3;
           break;
       }
       ...
       default:
       {
           item1;
           item2;
           break;
       }


to this:

   switch (arg) {
       case 0: {
           item1;
           item2;
           item3;
           break;
       }
       ...
       default: {
           item1;
           item2;
           break;
       }


Any easy way to customize cc-mode to do this?

No, but you can write easily an emacs command to do that.

(defun beautify-case-braces ()
  (interactive)
  (beginning-of-buffer)
  (while (re-search-forward "\\<\\(case .*:\\|default[ \t\n]*:\\)[ \t\n]*{" nil t)
     (let ((case-text (buffer-substring (match-beginning 1) (match-end 1))))
       (delete-region (match-beginning 0) (match-end 0))
       (insert case-text " {"))))
