| 3 | ;;; 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 | ;;; |
|---|
| 22 | ;;; C-u M-x byte-compile-file |
