| 29 | ;;; Commentary: |
| 30 | |
| 31 | ;; This is Sebastian Kremer's excellent dired-x.el (Dired Extra), version |
| 32 | ;; 1.191, hacked up for GNU Emacs 19. Redundant or conflicting material |
| 33 | ;; has been removed or renamed in order to work properly with dired of |
| 34 | ;; GNU Emacs 19. All suggestions or comments are most welcomed. |
| 35 | |
| 36 | ;; |
| 37 | ;; Please, PLEASE, *PLEASE* see the info pages. |
| 38 | ;; |
| 39 | |
| 40 | ;; BUGS: Type M-x dired-x-submit-report and a report will be generated. |
| 41 | |
| 42 | ;; INSTALLATION: In your ~/.emacs, |
| 43 | ;; |
| 44 | ;; (add-hook 'dired-load-hook |
| 45 | ;; (function (lambda () |
| 46 | ;; (load "dired-x") |
| 47 | ;; ;; Set global variables here. For example: |
| 48 | ;; ;; (setq dired-guess-shell-gnutar "gtar") |
| 49 | ;; ))) |
| 50 | ;; (add-hook 'dired-mode-hook |
| 51 | ;; (function (lambda () |
| 52 | ;; ;; Set buffer-local variables here. For example: |
| 53 | ;; ;; (setq dired-omit-files-p t) |
| 54 | ;; ))) |
| 55 | ;; |
| 56 | ;; At load time dired-x.el will install itself, redefine some functions, and |
| 57 | ;; bind some dired keys. *Please* see the info pages for more details. |
| 58 | |
| 59 | ;; CAUTION: If you are using a version of GNU Emacs earlier than 19.20 than |
| 60 | ;; you may have to edit dired.el. The copy of dired.el in GNU Emacs versions |
| 61 | ;; earlier than 19.20 incorrectly had the call to run-hooks *before* the call |
| 62 | ;; to provide. In such a case, it is possible that byte-compiling and/or |
| 63 | ;; loading dired can cause an infinite loop. To prevent this, make sure the |
| 64 | ;; line of code |
| 65 | ;; |
| 66 | ;; (run-hooks 'dired-load-hook) |
| 67 | ;; |
| 68 | ;; is the *last* executable line in the file dired.el. That is, make sure it |
| 69 | ;; comes *after* the line |
| 70 | ;; |
| 71 | ;; (provide 'dired) |
| 72 | ;; |
| 73 | ;; *Please* see the info pages for more details. |

| 99 | ;; When loaded this code redefines the following functions of GNU Emacs |
| 100 | ;; |
| 101 | ;; Function Found in this file of GNU Emacs |
| 102 | ;; -------- ------------------------------- |
| 103 | ;; dired-clean-up-after-deletion ../lisp/dired.el |
| 104 | ;; dired-find-buffer-nocreate ../lisp/dired.el |
| 105 | ;; dired-initial-position ../lisp/dired.el |
| 106 | ;; |
| 107 | ;; dired-add-entry ../lisp/dired-aux.el |
| 108 | ;; dired-read-shell-command ../lisp/dired-aux.el |
| 109 | ;; |
| 110 | ;; One drawback is that dired-x.el will load dired-aux.el as soon as dired is |
| 111 | ;; loaded. Thus, the advantage of separating out non-essential dired stuff |
| 112 | ;; into dired-aux.el and only loading when necessary will be lost. Please |
| 113 | ;; note also that some of the comments in dired.el and dired-aux.el are |
| 114 | ;; Kremer's that referred to the old dired-x.el. This now should be referring |
| 115 | ;; to this program. (This is also a good reason to call this dired-x.el |
| 116 | ;; instead of dired-x19.el.) |
