doc/openssl-c-indent.el

   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
