xref: /freebsd/crypto/openssl/doc/openssl-c-indent.el (revision cc68614da8232d8baaca0ae0d0dd8f890f06623e)
1;;; 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
25
26;;; For suggesting improvements, please send e-mail to levitte@openssl.org.

29;; 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
