27 : ;;; Commentary:
28 :
29 : ;; Emacs's traditional method for making buffer names unique adds <2>, <3>,
30 : ;; etc. to the end of (all but one of) the buffers. This file replaces
31 : ;; that behavior, for buffers visiting files and dired buffers, with a
32 : ;; uniquification that adds parts of the file name until the buffer names
33 : ;; are unique. For instance, buffers visiting /u/mernst/tmp/Makefile and
34 : ;; /usr/projects/zaphod/Makefile would be named Makefile|tmp and
35 : ;; Makefile|zaphod, respectively (instead of Makefile and Makefile<2>).
36 : ;; Other buffer name styles are also available.
37 :
38 : ;; To use this file, do (require 'uniquify)
39 : ;; and set uniquify-buffer-name-style to one of its non-nil alternative values.
40 :
41 : ;; For other options, see "User-visible variables", below.
42 :
43 : ;; A version of uniquify.el that works under Emacs 18, Emacs 19, XEmacs,
44 : ;; and InfoDock is available from the maintainer.
