;; Provides the google C/C++ coding style. You may wish to add
|
|
;; `google-set-c-style' to your `c-mode-common-hook' after requiring this
|
|
;; file. For example:
|
|
;;
|
|
;; (add-hook 'c-mode-common-hook 'google-set-c-style)
|
|
;;
|
|
;; If you want the RETURN key to go to the next line and space over
|
|
;; to the right place, add this to your .emacs right after the load-file:
|
|

|

;; (add-hook 'c-mode-common-hook 'google-make-newline-indent)
