-
- ;;; Commentary:
-
- ;; This is Sebastian Kremer's excellent dired-x.el (Dired Extra), version
- ;; 1.191, hacked up for GNU Emacs 19. Redundant or conflicting material
- ;; has been removed or renamed in order to work properly with dired of
- ;; GNU Emacs 19. All suggestions or comments are most welcomed.
-
- ;;
- ;; Please, PLEASE, *PLEASE* see the info pages.
- ;;
-
- ;; BUGS: Type M-x dired-x-submit-report and a report will be generated.
-
- ;; INSTALLATION: In your ~/.emacs,
- ;;
- ;; (add-hook 'dired-load-hook
- ;; (function (lambda ()
- ;; (load "dired-x")
- ;; ;; Set global variables here. For example:
- ;; ;; (setq dired-guess-shell-gnutar "gtar")
- ;; )))
- ;; (add-hook 'dired-mode-hook
- ;; (function (lambda ()
- ;; ;; Set buffer-local variables here. For example:
- ;; ;; (setq dired-omit-files-p t)
- ;; )))
- ;;
- ;; At load time dired-x.el will install itself, redefine some functions, and
- ;; bind some dired keys. *Please* see the info pages for more details.
-
- ;; CAUTION: If you are using a version of GNU Emacs earlier than 19.20 than
- ;; you may have to edit dired.el. The copy of dired.el in GNU Emacs versions
- ;; earlier than 19.20 incorrectly had the call to run-hooks *before* the call
- ;; to provide. In such a case, it is possible that byte-compiling and/or
- ;; loading dired can cause an infinite loop. To prevent this, make sure the
- ;; line of code
- ;;
- ;; (run-hooks 'dired-load-hook)
- ;;
- ;; is the *last* executable line in the file dired.el. That is, make sure it
- ;; comes *after* the line
- ;;
- ;; (provide 'dired)
- ;;
- ;; *Please* see the info pages for more details.
-
- ;; User defined variables:
- ;;
- ;; dired-bind-vm
- ;; dired-vm-read-only-folders
- ;; dired-bind-jump
- ;; dired-bind-info
- ;; dired-bind-man
- ;; dired-x-hands-off-my-keys
- ;; dired-find-subdir
- ;; dired-enable-local-variables
- ;; dired-local-variables-file

- ;; dired-guess-shell-alist-user
- ;; dired-clean-up-buffers-too
- ;; dired-omit-files-p
- ;; dired-omit-files
- ;; dired-omit-extensions
- ;;
- ;; To find out more about these variables, load this file, put your cursor at
- ;; the end of any of the variable names, and hit C-h v [RET]. *Please* see
- ;; the info pages for more details.
-
- ;; When loaded this code redefines the following functions of GNU Emacs
- ;;
- ;; Function Found in this file of GNU Emacs
- ;; -------- -------------------------------
- ;; dired-clean-up-after-deletion ../lisp/dired.el
- ;; dired-find-buffer-nocreate ../lisp/dired.el
- ;; dired-initial-position ../lisp/dired.el
- ;;
- ;; dired-add-entry ../lisp/dired-aux.el
- ;; dired-read-shell-command ../lisp/dired-aux.el
- ;;
- ;; One drawback is that dired-x.el will load dired-aux.el as soon as dired is
- ;; loaded. Thus, the advantage of separating out non-essential dired stuff
- ;; into dired-aux.el and only loading when necessary will be lost. Please
- ;; note also that some of the comments in dired.el and dired-aux.el are
- ;; Kremer's that referred to the old dired-x.el. This now should be referring
- ;; to this program. (This is also a good reason to call this dired-x.el
- ;; instead of dired-x19.el.)
-
-
- ;;; Code:
-
- ;; LOAD.
-
- ;; This is a no-op if dired-x is being loaded via `dired-load-hook'. It is
- ;; here in case the user has autoloaded dired-x via the dired-jump key binding
- ;; (instead of autoloading to dired as is suggested in the info-pages).
