5.3 Ignoring Buffers and Files
==============================
Ido is capable of ignoring buffers, directories, files and extensions
using regular expression.
-- User Option: ido-ignore-buffers
This variable takes a list of regular expressions for buffers to
ignore in ‘ido-switch-buffer’.
-- User Option: ido-ignore-directories
This variable takes a list of regular expressions for
(sub)directories names to ignore in ‘ido-dired’ and
‘ido-find-file’.
-- User Option: ido-ignore-files
This variable takes a list of regular expressions for files to
ignore in ‘ido-find-file’.
-- User Option: ido-ignore-unc-host-regexps
This variable takes a list of regular expressions matching UNC
hosts to ignore. The letter case will be ignored if
‘ido-downcase-unc-hosts’ is non-‘nil’.
To make Ido use ‘completion-ignored-extensions’ you need to enable
it:
(setq ido-ignore-extensions t)
Now you can customize ‘completion-ignored-extensions’ as well. Go
ahead and add all the useless object files, backup files, shared library
files and other computing flotsam you don’t want Ido to show.
*Please notice:* Ido will still complete the ignored elements if it
would otherwise not show any other matches. So if you type out the name
of an ignored file, Ido will still let you open it just fine.
