We don't want an indentation step inside a 'extern "C" {' .. '}'
block. Apparently, cc-mode has a c-offsets-alist keyword to allow
exactly this.

;;; This Emacs Lisp file defines a C indentation style for OpenSSL.
|
|
;;;
|
|
;;; This definition is for the "CC mode" package, which is the default
|
|
;;; mode for editing C source files in Emacs 20, not for the older
|
|
;;; c-mode.el (which was the default in less recent releases of Emacs 19).
|
|
;;;
|
|
;;; Recommended use is to add this line in your .emacs:
|
|
;;;
|
|
;;; (load (expand-file-name "~/PATH/TO/openssl-c-indent.el"))
|
|
;;;
|
|
;;; To activate this indentation style, visit a C file, type
|
|
;;; M-x c-set-style <RET> (or C-c . for short), and enter "eay".
|
|
;;; To toggle the auto-newline feature of CC mode, type C-c C-a.
|
|
;;;
|
|
;;; If you're an OpenSSL developer, you might find it more comfortable
|
|
;;; to have this style be permanent in your OpenSSL development
|
|
;;; directory. To have that, please perform this:
|
|
;;;
|
|
;;; M-x add-dir-local-variable <RET> c-mode <RET> c-file-style <RET>
|
|
;;; "OpenSSL-II" <RET>
|
|
;;;
|
|
;;; A new buffer with .dir-locals.el will appear. Save it (C-x C-s).
|
|
;;;
|
|
;;; Alternatively, have a look at dir-locals.example.el
|
|
|
|
;;; For suggesting improvements, please send e-mail to levitte@openssl.org.

;; Note, it could be easy to inherit from the "gnu" style... however,
|
|

|
|
;; so I've chosen to copy the "gnu" style values explicitly instead
