30 ;;; This is Sebastian Kremer's excellent dired-x.el (Dired Extra), version
31 ;;; 1.191, hacked up for GNU Emacs 19. Redundant or conflicting material
32 ;;; has been removed or renamed in order to work properly with dired of
33 ;;; GNU Emacs 19. All suggestions or comments are most welcomed.
35 ;;; *Please* see the info pages.
37 ;;; BUGS: Type M-x dired-x-submit-report and a report will be generated.
39 ;;; INSTALLATION: In your ~/.emacs,
41 ;;; (add-hook 'dired-load-hook
42 ;;; (function (lambda ()
44 ;;; ;; Set variables here. For example:
45 ;;; ;; (setq dired-guess-shell-gnutar "gtar")
46 ;;; ;; (setq dired-omit-files-p t)
49 ;;; At load time dired-x.el will install itself, redefine some functions, and
50 ;;; bind some dired keys. *Please* see the info pages for more details.
52 ;;; User defined variables:
55 ;;; dired-vm-read-only-folders
60 ;;; dired-enable-local-variables
61 ;;; dired-local-variables-file
62 ;;; dired-guess-shell-gnutar
63 ;;; dired-guess-shell-gzip-quiet
64 ;;; dired-guess-shell-znew-switches
65 ;;; dired-guess-shell-alist-user
66 ;;; dired-clean-up-buffers-too
67 ;;; dired-omit-files-p
69 ;;; dired-omit-extensions
71 ;;; To find out more about these variables, load this file, put your cursor at
72 ;;; the end of any of the variable names, and hit C-h v [RET]. *Please* see
73 ;;; the info pages for more details.
75 ;;; When loaded this code redefines the following functions of GNU Emacs
77 ;;; Function Found in this file of GNU Emacs
78 ;;; -------- -------------------------------
79 ;;; dired-clean-up-after-deletion ../lisp/dired.el
80 ;;; dired-find-buffer-nocreate ../lisp/dired.el
81 ;;; dired-initial-position ../lisp/dired.el
82 ;;; dired-up-directory ../lisp/dired.el
84 ;;; dired-add-entry ../lisp/dired-aux.el
85 ;;; dired-read-shell-command ../lisp/dired-aux.el
87 ;;; One drawback is that dired-x.el will load dired-aux.el as soon as dired is
88 ;;; loaded. Thus, the advantage of separating out non-essential dired stuff
89 ;;; into dired-aux.el and only loading when necessary will be lost. Please
90 ;;; note also that some of the comments in dired.el and dired-aux.el are
91 ;;; Kremer's that referred to the old dired-x.el. This now should be referring
92 ;;; to this program. (This is also a good reason to call this dired-x.el
93 ;;; instead of dired-x19.el.)
100 ;;; This is a no-op if dired-x is being loaded via `dired-load-hook'. It is
101 ;;; here in case the user has autoloaded dired-x via the dired-jump key binding
102 ;;; (instead of autoloading to dired as is suggested in the info-pages).
106 ;;; We will redefine some functions and also need some macros so we need to
107 ;;; load dired stuff of GNU Emacs.
