;;; Commentary:
;; Ido - interactive do - switches between buffers and opens files and
;; directories with a minimum of keystrokes. It is a superset of
;; iswitchb, the interactive buffer switching package by Stephen Eglen.
;; Interactive substring matching
;; ------------------------------
;;
;; As you type in a substring, the list of buffers or files currently
;; matching the substring are displayed as you type. The list is
;; ordered so that the most recent buffers or files visited come at
;; the start of the list.
;;
;; The buffer or file at the start of the list will be the one visited
;; when you press RETURN. By typing more of the substring, the list is
;; narrowed down so that gradually the buffer or file you want will be
;; at the top of the list. Alternatively, you can use C-s and C-r (or
;; the right and left arrow keys) to rotate buffer or file names in the
;; list until the one you want is at the top of the list.
;;
;; Completion is also available so that you can see what is common to
;; all of the matching buffers or files as you type.
;;
;; Example:
;;
;; If I have two buffers called "123456" and "123", with "123456" the
;; most recent, when I use ido-switch-buffer, I first of all get
;; presented with the list of all the buffers
;;
;; Buffer: {123456 | 123}
;;
;; If I then press 2:
;; Buffer: 2[3]{123456 | 123}
;;
;; The list in {...} are the matching buffers, most recent first
;; (buffers visible in the current frame are put at the end of the
;; list by default). At any time I can select the item at the head of
;; the list by pressing RET. I can also put the first element at the
;; end of the list by pressing C-s or [right], or bring the last
;; element to the head of the list by pressing C-r or [left].
;;
;; The item in [...] indicates what can be added to my input by
;; pressing TAB. In this case, I will get "3" added to my input.
;; So, I press TAB:
;; Buffer: 23{123456 | 123}
;;
;; At this point, I still have two matching buffers.
;; If I want the first buffer in the list, I simply press RET. If I
;; wanted the second in the list, I could press C-s to move it to the
;; top of the list and then RET to select it.
;;
;; However, if I type 4, I only have one match left:
;; Buffer: 234[123456]
;;
;; Since there is only one matching buffer left, it is given in [] and
;; it is shown in the `ido-only-match' face (ForestGreen). I can now
;; press TAB or RET to go to that buffer.
;;
;; If I want to create a new buffer named "234", I press C-j instead of
;; TAB or RET.
;;
;; If instead, I type "a":
;; Buffer: 234a [No match]
;; There are no matching buffers. If I press RET or TAB, I can be
;; prompted to create a new buffer called "234a".
;;
;; Of course, where this function comes in really useful is when you
;; can specify the buffer using only a few keystrokes. In the above
;; example, the quickest way to get to the "123456" file would be
;; just to type 4 and then RET (assuming there isn't any newer buffer
;; with 4 in its name).
;; Likewise, if you use C-x C-f (ido-find-file), the list of files and
;; directories in the current directory is provided in the same
;; fashion as the buffers above. The files and directories are
;; normally sorted in alphabetical order, but the most recently
;; visited directory is placed first to speed up navigating to
;; directories that you have visited recently.
;;
;; In addition to scrolling through the list using [right] and [left],
;; you can use [up] and [down] to quickly scroll the list to the next
;; or previous subdirectory.
;;
;; To go down into a subdirectory, and continue the file selection on
;; the files in that directory, simply move the directory to the head
;; of the list and hit RET.
;;
;; To go up to the parent directory, delete any partial file name
;; already specified (e.g. using [backspace]) and hit [backspace].
;;
;; To go to the root directory (on the current drive), enter two
;; slashes. On MS-DOS or Windows, to select the root of another
;; drive, enter X:/ where X is the drive letter. You can also visit
;; files on other hosts using the ange-ftp notations `/host:' and
;; `/user@host:'. See the variable `ido-slow-ftp-hosts' if you want
;; to inhibit the ido substring matching for ftp access.
;;
;; If for some reason you cannot specify the proper file using
;; ido-find-file, you can press C-f to enter the normal find-file.
;; You can also press C-b to drop into ido-switch-buffer.
;; See the doc string of ido-switch-buffer and ido-find-file for full
;; keybindings and features.
;; (describe-function 'ido-find-file)
;; Hidden buffers and files
;; ------------------------
;;
;; Normally, ido does not include hidden buffers (whose name starts
;; with a space) and hidden files and directories (whose name starts
;; with `.') in the list of possible completions. However, if the
;; substring you enter does not match any of the visible buffers or
;; files, ido will automatically look for completions among the hidden
;; buffers or files.
;;
;; You can toggle display of the hidden buffers and files with C-a.
;; Additional functionality
;; ------------------------
;;
;; After C-x b, the buffer at the head of the list can be killed by
;; pressing C-k. If the buffer needs saving, you will be queried
;; before the buffer is killed.
;;
;; Likewise, after C-x C-f, you can delete (i.e. physically remove)
;; the file at the head of the list with C-k. You will always be
;; asked for confirmation before the file is deleted.
;;
;; If you enter C-x b to switch to a buffer visiting a given file, and
;; you find that the file you are after is not in any buffer, you can
;; press C-f to immediately drop into ido-find-file. And you can
;; switch back to buffer selection with C-b.
;; Prefix matching
;; ---------------
;;
;; The standard way of completion with Unix-shells and Emacs is to insert a
;; PREFIX and then hitting TAB (or another completion key). Cause of this
;; behavior has become second nature to a lot of Emacs users `ido' offers in
;; addition to the default substring-matching-method (look above) also the
;; prefix-matching-method. The kind of matching is the only difference to
;; the description of the substring-matching above.
;;
;; You can toggle prefix matching with C-p.
;;
;; Example:
;;
;; If you have again two Buffers "123456" and "123" then hitting "2" does
;; not match because "2" is not a PREFIX in any of the buffer-names.
;; Flexible matching
;; -----------------
;;
;; If you set ido-enable-flex-matching, ido will do a more flexible
;; matching (unless regexp matching is active) to find possible matches
;; among the available buffer or file names if no matches are found using
;; the normal prefix or substring matching.
;;
;; The flexible matching implies that any item which simply contains all
;; of the entered characters in the specified sequence will match.
;;
;; Example:
;;
;; If you have four files "alpha", "beta", "gamma", and "delta",
;; entering "aa" will match "alpha" and "gamma", while "ea" matches
;; "beta" and "delta". If prefix matching is also active, "aa" only
;; matches "alpha", while "ea" does not match any files.
;; Regexp matching
;; ---------------
;;
;; There is limited provision for regexp matching within ido,
;; enabled through `ido-enable-regexp' (toggle with C-t).
;; This allows you to type `[ch]$' for example and see all file names
;; ending in `c' or `h'.
;;
;; Note: ido-style completion is inhibited when you enable regexp matching.
;; Customization
;; -------------
;;
;; Customize the `ido' group to change the `ido' functionality.
;;
;; To modify the keybindings, use the ido-setup-hook. For example:
;;(add-hook 'ido-setup-hook 'ido-my-keys)
;;
;;(defun ido-my-keys ()
;; "Add my keybindings for ido."
;; (define-key ido-completion-map " " 'ido-next-match)
;; )
;; Seeing all the matching buffers or files
;; ----------------------------------------
;;
;; If you have many matching files, they may not all fit onto one
;; line of the minibuffer. Normally, the minibuffer window will grow
;; to show you more of the matching files (depending on the setting
;; of the variables `resize-mini-windows' and `max-mini-window-height').
;; If you want ido to behave differently from the default minibuffer
;; resizing behavior, set the variable `ido-max-window-height'.
;;
;; Also, to improve the responsiveness of ido, the maximum number of
;; matching items is limited to 12, but you can increase or removed
;; this limit via the `ido-max-prospects' variable.
;; To see a full list of all matching buffers in a separate buffer,
;; hit ? or press TAB when there are no further completions to the
;; substring. Repeated TAB presses will scroll you through this
;; separate buffer.
;; Changing the list of files
;; --------------------------
;; By default, the list of current files is most recent first,
;; oldest last, with the exception that the files visible in the
;; current frame are put at the end of the list. A hook exists to
;; allow other functions to order the list. For example, if you add:
;;
;; (add-hook 'ido-make-buffer-list-hook 'ido-summary-buffers-to-end)
;;
;; then all files matching "Summary" are moved to the end of the
;; list. (I find this handy for keeping the INBOX Summary and so on
;; out of the way.) It also moves files matching "output\*$" to the
;; end of the list (these are created by AUCTeX when compiling.)
;; Other functions could be made available which alter the list of
;; matching files (either deleting or rearranging elements.)
;; Highlighting
;; ------------
;; The highlighting of matching items is controlled via ido-use-faces.
;; The faces used are ido-first-match, ido-only-match and
;; ido-subdir.
;; Coloring of the matching item was suggested by
;; Carsten Dominik (dominik@strw.leidenuniv.nl).
;; Replacement for read-buffer and read-file-name
;; ----------------------------------------------
;; ido-read-buffer and ido-read-file-name have been written to be drop
;; in replacements for the normal buffer and file name reading
;; functions `read-buffer' and `read-file-name'.
;; To use ido for all buffer and file selections in Emacs, customize the
;; variable `ido-everywhere'.
;; Using ido-like behavior in other Lisp packages
;; -----------------------------------------------
;; If you don't want to rely on the `ido-everywhere' functionality,
;; ido-read-buffer, ido-read-file-name, and ido-read-directory-name
;; can be used by other packages to read a buffer name, a file name,
;; or a directory name in the `ido' way.
;;; Acknowledgments
;; Infinite amounts of gratitude goes to Stephen Eglen <stephen@cns.ed.ac.uk>
;; who wrote iswitch-buffer mode - from which I ripped off 99% of the code
;; for ido-switch-buffer and found the inspiration for ido-find-file.
;; The ido package would never have existed without his work.
;; Also thanks to Klaus Berndl, Rohit Namjoshi, Robert Fenk, Alex
;; Schroeder, Bill Benedetto, Stephen Eglen, and many others for bug
;; fixes and improvements.
;;; History
;; Since I discovered Stephen Eglen's excellent iswitchb package, I just
;; couldn't live without it, but once being addicted to switching buffers
;; with a minimum of keystrokes, I soon found that opening files in the
;; old-fashioned way was just too slow - so I decided to write a package
;; which could open files with the same speed and ease as iswitchb could
;; switch buffers.
;; I originally wrote a separate ifindf.el package based on a copy of
;; iswitchb.el, which did for opening files what iswitchb did for
;; switching buffers. Along the way, I corrected a few errors in
;; ifindf which could have found its way back into iswitchb, but since
;; most of the functionality of the two package was practically
;; identical, I decided that the proper thing to do was to merge my
;; ifindf package back into iswitchb.
;;
;; This is basically what ido (interactively do) is all about; but I
;; found it awkward to merge my changes into the "iswitchb-" namespace,
;; so I invented a common "ido-" namespace for the merged packages.
;;
;; This version is based on ido.el version 1.57 released on
;; gnu.emacs.sources adapted for Emacs 22.1 to use command remapping
;; and optionally hooking the read-buffer and read-file-name functions.
;;
;; Prefix matching was added by Klaus Berndl <klaus.berndl@sdm.de> based on
;; an idea of Yuji Minejima <ggb01164@nifty.ne.jp> and his mcomplete-package.
;;; Code:
(defvar recentf-list)
;;; User Variables
;;
;; These are some things you might want to change.

Essentially it works as follows: Say you are visiting a file and
the buffer gets cleaned up by midnight.el. Later, you want to
switch to that buffer, but find it's no longer open. With virtual
buffers enabled, the buffer name stays in the buffer list (using
the `ido-virtual' face, and always at the end), and if you select
it, it opens the file back up again. This allows you to think
less about whether recently opened files are still open or not.
Most of the time you can quit Emacs, restart, and then switch to
a file buffer that was previously open as if it still were. This
feature relies upon the `recentf' package, which will be enabled
if this variable is configured to a non-nil value."
