How to enable ido-completing-read correctly

Question

So there is ido-completing-read that seems perfect to assign to completing-read-function. There is no customization interface though.

How is the user supposed to enable ido-completing-read for all completing reads?

Emacswiki page does not mention completing-read-function so I guess wiki is older than the function (it uses defadvice). Does not really answer my question.... — Gracjan Polak, Commented Aug 24, 2015 at 20:32
Hmm... you could either try the package ido-ubiquitous, or else just set the variable by hand: (setq completing-read-function #'completing-read-ido). — Dan, Commented Aug 24, 2015 at 20:43
(setq completing-read-function #'completing-read-ido) won't work because completing-read-ido doesn't handle all the different collection types that completing-read-function might receive (bug#15430). — npostavs, Commented Aug 24, 2015 at 22:41

This is not a convention it's rather that some packages support it while ido-ubiquitous is just a hack to use ido wherever possible.

Basic setup is just:

(setq
 ido-create-new-buffer    'always
 ido-enable-flex-matching t
 ido-everywhere           t)

(ido-mode 1) ; ido for switch-buffer and find-file

Next, to use it everywhere install ido-ubiquitous and activate it:

(ido-ubiquitous-mode 1) ; use IDO everywhere

ido-vertical is highly recommended:

(setq ido-vertical-define-keys 'C-n-and-C-p-only)

(ido-vertical-mode 1) ; display IDO vertically

Don't forget about Smex.
