I am using ido-mode to select files from Emacs. This works well for most cases, but for some cases I would like to modify the files that are shown in the completion buffer with ido-find-file.

In some folders I have a lot of *.bak files, and I would like to have the possiblity to remove them from the completion buffer by pressing the F1 key, for example. This is how far I got on this task:

(add-hook 'ido-minibuffer-setup-hook 'ido-my-keys)

(defun ido-my-keys ()
  (define-key ido-file-completion-map (kbd "<f1>") 'my-modify-files))

(defun my-modify-files ()
  (interactive)
  (message-box "Here I would like to delete the .bak files from the minibuffer"))

ido-mode has built-in support for hiding files matching specific regexps. All you need to do is add \.bak to ido-ignore-files:

(add-to-list 'ido-ignore-files "\.bak")

After invoking ido-find-file, you can then hit C-a (ido-toggle-ignore) to toggle hiding of .bak files.

    @HåkonHægland Great! :) If you're interested, have a look at the documentation of ido-find-file (C-h f ido-find-file RET) for a full list of commands and options you can toggle while the Ido prompt is active. – itsjeyd Nov 13 '14 at 10:12
