;;; You only need to use this file if you're using a version of Emacs
|
| 4 |
|
|
;;; prior to 20.1 to work on GDB. The only difference between this
|
| 5 |
|
|
;;; and the standard add-log.el provided with 19.34 is that it
|
| 6 |
|
|
;;; generates dates using the terser format used by Emacs 20. This is
|
| 7 |
|
|
;;; the format recommended for use in GDB ChangeLogs.
|
| 8 |
|
|
;;;
|
| 9 |
|
|
;;; To use this code, you should create a directory `~/elisp', save the code
|
| 10 |
|
|
;;; below in `~/elisp/add-log.el', and then put something like this in
|
| 11 |
|
|
;;; your `~/.emacs' file, to tell Emacs where to find it:
|
| 12 |
|
|
;;;
|
| 13 |
|
|
;;; (setq load-path
|
| 14 |
|
|
;;; (cons (expand-file-name "~/elisp")
|
| 15 |
|
|
;;; load-path))
|
| 16 |
|
|
;;;
|
| 17 |
|
|
;;; If you want, you can also byte-compile it --- it'll run a little
|
| 18 |
|
|
;;; faster, and use a little less memory. (Not that those matter much for
|
| 19 |
|
|
;;; this file.) To do that, after you've saved the text as
|
| 20 |
|
|
;;; ~/elisp/add-log.el, bring it up in Emacs, and type
|
| 21 |
|
|
