;;; Commentary:
|
|
|
|
;; wdired.el (the "w" is for writable) provides an alternative way of
|
|
;; renaming files.
|
|
;;
|
|
;; Have you ever wanted to use `C-x r t' (`string-rectangle'), `M-%'
|
|
;; (`query-replace'), `M-c' (`capitalize-word'), etc... to change the
|
|
;; name of the files in a Dired buffer? Now you can do this. All the
|
|
;; power of Emacs commands are available when renaming files!
|
|
;;
|
|
;; This package provides a function that makes the filenames of a
|
|
;; Dired buffer editable, by changing the buffer mode (which inhibits
|
|
;; all of the commands of Dired mode). Here you can edit the names of
|
|
;; one or more files and directories, and when you press `C-c C-c',
|
|
;; the renaming takes effect and you are back to Dired mode.
|
|
;;
|
|
;; Other things you can do with WDired:
|
|
;;
|
|
;; - Move files to another directory (by typing their path,
|
|
;; absolute or relative, as a part of the new filename).
|
|
;;
|
|
;; - Change the target of symbolic links.
|
|
;;
|
|
;; - Change the permission bits of the filenames (in systems with a
|
|
;; working unix-alike "chmod"). See and customize the variable
|
|
;; `wdired-allow-to-change-permissions'. To change a single char
|
|
;; (toggling between its two more usual values), you can press the
|
|
;; space bar over it or left-click the mouse. To set any char to a
|
|
;; specific value (this includes the SUID, SGID and STI bits) you
|
|
;; can use the key labeled as the letter you want. Please note that
|
|
;; permissions of the links cannot be changed in that way, because
|
|
;; the change would affect to their targets, and this would not be
|
|
;; WYSIWYG :-).
|
|
;;
|
|
;; - Mark files for deletion, by deleting their whole filename.
|
|
|
|
;; * Usage:
|
|
|
|
;; You can edit the names of the files by typing `C-x C-q' or
|
|
;; `M-x wdired-change-to-wdired-mode'. Use `C-c C-c' when
|
|
;; finished or `C-c C-k' to abort.
|
|
;;
|
|
;; You can customize the behavior of this package from the "WDired"
|
|
;; menu or with `M-x customize-group RET wdired RET'.
