;;; This Emacs Lisp file defines a C indentation style for OpenSSL.

2
;;;

3
;;; This definition is for the "CC mode" package, which is the default

4
;;; mode for editing C source files in Emacs 20, not for the older

5
;;; c-mode.el (which was the default in less recent releases of Emacs 19).

6
;;;

7
;;; Recommended use is to add this line in your .emacs:

8
;;;

9
;;;   (load (expand-file-name "~/PATH/TO/openssl-c-indent.el"))

10
;;;

11
;;; To activate this indentation style, visit a C file, type

12
;;; M-x c-set-style <RET> (or C-c . for short), and enter "eay".

13
;;; To toggle the auto-newline feature of CC mode, type C-c C-a.

14
;;;

15
;;; If you're an OpenSSL developer, you might find it more comfortable

16
;;; to have this style be permanent in your OpenSSL development

17
;;; directory.  To have that, please perform this:

18
;;;

19
;;;    M-x add-dir-local-variable <RET> c-mode <RET> c-file-style <RET>

20
;;;    "OpenSSL-II" <RET>

21
;;;

22
;;; A new buffer with .dir-locals.el will appear.  Save it (C-x C-s).

23
;;;

24
;;; Alternatively, have a look at dir-locals.example.el

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

30
;; one never knows if that style will change somewhere in the future,

31
;; so I've chosen to copy the "gnu" style values explicitly instead

32
;; and mark them with a comment.                // RLevitte 2015-08-31
