bug#11954: 24.1.50; Ido in dired buffers

[Marius Hofert]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

I use dired mode a lot and have recently started to use ido mode. I have the
following settings in .emacs to use ido mode in buffers and for finding files:

(ido-mode 1); enable ido-mode
(setq ido-enable-flex-matching t); flexibly match names via fuzzy matching
(ido-everywhere t); use ido-mode everywhere, in buffers and for finding files
(setq ido-use-filename-at-point 'guess); for find-file-at-point
(setq ido-use-url-at-point t); look for URLs at point
(setq ffap-require-prefix t); get find-file-at-point with C-u C-x C-f (used to
be C-x C-f without ido)

I was wondering if it is possible to use ido mode when copying ('C') or renaming
('R') files in dired mode. I asked on stackoverflow (see
http://stackoverflow.com/questions/11505878/get-ido-in-dired-buffers) and as the
user "assem" pointed out, I should submit this question as a bug report/feature
request. By calling ido-everywhere correctly, 'C' is already working in dired
mode. "assem" also gave a hint towards a solution for 'R':

,----
| The problem is the 'ido property in the symbol for 'dired-do-rename has been 
specifically set to 'ignore. As a result, inside of ido-read-file-name the (and 
...) clause that falls into completing-read fails, and it jumps into the 
fallback, ultimately to read-file-name-default
`----

and

,----
| Surely they had a very good reason for this, but I will say that doing (put 
'dired-do-rename 'ido 'find-file) gives an ido-completing read and had no 
adverse consequences for me to rename a basic file and directory. I don't 
recommend this though - instead I would submit a bug report/feature request
`----

It would be great if dired mode ("in ido mode") would work as expected and use
ido when 'R'-ing files. 

Cheers,

Marius
