26 ;;; Commentary:
28 ;; Ido - interactive do - switches between buffers and opens files and
29 ;; directories with a minimum of keystrokes. It is a superset of
30 ;; iswitchb, the interactive buffer switching package by Stephen Eglen.
32 ;; Interactive substring matching
33 ;; ------------------------------
35 ;; As you type in a substring, the list of buffers or files currently
36 ;; matching the substring are displayed as you type. The list is
37 ;; ordered so that the most recent buffers or files visited come at
38 ;; the start of the list.
40 ;; The buffer or file at the start of the list will be the one visited
41 ;; when you press RETURN. By typing more of the substring, the list is
42 ;; narrowed down so that gradually the buffer or file you want will be
43 ;; at the top of the list. Alternatively, you can use C-s and C-r (or
44 ;; the right and left arrow keys) to rotate buffer or file names in the
45 ;; list until the one you want is at the top of the list.
47 ;; Completion is also available so that you can see what is common to
48 ;; all of the matching buffers or files as you type.
50 ;; Example:
52 ;; If I have two buffers called "123456" and "123", with "123456" the
53 ;; most recent, when I use ido-switch-buffer, I first of all get
54 ;; presented with the list of all the buffers
56 ;; Buffer: {123456 | 123}
58 ;; If I then press 2:
59 ;; Buffer: 2[3]{123456 | 123}
61 ;; The list in {...} are the matching buffers, most recent first
62 ;; (buffers visible in the current frame are put at the end of the
63 ;; list by default). At any time I can select the item at the head of
64 ;; the list by pressing RET. I can also put the first element at the
65 ;; end of the list by pressing C-s or [right], or bring the last
66 ;; element to the head of the list by pressing C-r or [left].
68 ;; The item in [...] indicates what can be added to my input by
69 ;; pressing TAB. In this case, I will get "3" added to my input.
71 ;; So, I press TAB:
72 ;; Buffer: 23{123456 | 123}
74 ;; At this point, I still have two matching buffers.
75 ;; If I want the first buffer in the list, I simply press RET. If I
76 ;; wanted the second in the list, I could press C-s to move it to the
77 ;; top of the list and then RET to select it.
79 ;; However, if I type 4, I only have one match left:
80 ;; Buffer: 234[123456]
82 ;; Since there is only one matching buffer left, it is given in [] and
83 ;; it is shown in the `ido-only-match' face (ForestGreen). I can now
84 ;; press TAB or RET to go to that buffer.
86 ;; If I want to create a new buffer named "234", I press C-j instead of
87 ;; TAB or RET.
89 ;; If instead, I type "a":
90 ;; Buffer: 234a [No match]
91 ;; There are no matching buffers. If I press RET or TAB, I can be
92 ;; prompted to create a new buffer called "234a".
94 ;; Of course, where this function comes in really useful is when you
95 ;; can specify the buffer using only a few keystrokes. In the above
96 ;; example, the quickest way to get to the "123456" file would be
97 ;; just to type 4 and then RET (assuming there isn't any newer buffer
98 ;; with 4 in its name).
100 ;; Likewise, if you use C-x C-f (ido-find-file), the list of files and
101 ;; directories in the current directory is provided in the same
102 ;; fashion as the buffers above. The files and directories are
103 ;; normally sorted in alphabetical order, but the most recently
104 ;; visited directory is placed first to speed up navigating to
105 ;; directories that you have visited recently.
107 ;; In addition to scrolling through the list using [right] and [left],
108 ;; you can use [up] and [down] to quickly scroll the list to the next
109 ;; or previous subdirectory.
111 ;; To go down into a subdirectory, and continue the file selection on
112 ;; the files in that directory, simply move the directory to the head
113 ;; of the list and hit RET.
115 ;; To go up to the parent directory, delete any partial file name
116 ;; already specified (e.g. using [backspace]) and hit [backspace].
118 ;; To go to the root directory (on the current drive), enter two
119 ;; slashes. On MS-DOS or Windows, to select the root of another
120 ;; drive, enter X:/ where X is the drive letter. You can also visit
121 ;; files on other hosts using the ange-ftp notations `/host:' and
122 ;; `/user@host:'. See the variable `ido-slow-ftp-hosts' if you want
123 ;; to inhibit the ido substring matching for ftp access.
125 ;; If for some reason you cannot specify the proper file using
126 ;; ido-find-file, you can press C-f to enter the normal find-file.
127 ;; You can also press C-b to drop into ido-switch-buffer.
129 ;; See the doc string of ido-switch-buffer and ido-find-file for full
130 ;; keybindings and features.
131 ;; (describe-function 'ido-find-file)
133 ;; Hidden buffers and files
134 ;; ------------------------
136 ;; Normally, ido does not include hidden buffers (whose name starts
137 ;; with a space) and hidden files and directories (whose name starts
138 ;; with `.') in the list of possible completions. However, if the
139 ;; substring you enter does not match any of the visible buffers or
140 ;; files, ido will automatically look for completions among the hidden
141 ;; buffers or files.
143 ;; You can toggle display of the hidden buffers and files with C-a.
145 ;; Additional functionality
146 ;; ------------------------
148 ;; After C-x b, the buffer at the head of the list can be killed by
149 ;; pressing C-k. If the buffer needs saving, you will be queried
150 ;; before the buffer is killed.
152 ;; Likewise, after C-x C-f, you can delete (i.e. physically remove)
153 ;; the file at the head of the list with C-k. You will always be
154 ;; asked for confirmation before the file is deleted.
156 ;; If you enter C-x b to switch to a buffer visiting a given file, and
157 ;; you find that the file you are after is not in any buffer, you can
158 ;; press C-f to immediately drop into ido-find-file. And you can
159 ;; switch back to buffer selection with C-b.
161 ;; Prefix matching
162 ;; ---------------
164 ;; The standard way of completion with Unix-shells and Emacs is to insert a
165 ;; PREFIX and then hitting TAB (or another completion key). Cause of this
166 ;; behavior has become second nature to a lot of emacs users `ido' offers in
167 ;; addition to the default substring-matching-method (look above) also the
168 ;; prefix-matching-method. The kind of matching is the only difference to
169 ;; the description of the substring-matching above.
171 ;; You can toggle prefix matching with C-p.
173 ;; Example:
175 ;; If you have again two Buffers "123456" and "123" then hitting "2" does
176 ;; not match because "2" is not a PREFIX in any of the buffer-names.
178 ;; Flexible matching
179 ;; -----------------
181 ;; If you set ido-enable-flex-matching, ido will do a more flexible
182 ;; matching (unless regexp matching is active) to find possible matches
183 ;; among the available buffer or file names if no matches are found using
184 ;; the normal prefix or substring matching.
186 ;; The flexible matching implies that any item which simply contains all
187 ;; of the entered characters in the specified sequence will match.
189 ;; Example:
191 ;; If you have four files "alpha", "beta", "gamma", and "delta",
192 ;; entering "aa" will match "alpha" and "gamma", while "ea" matches
193 ;; "beta" and "delta". If prefix matching is also active, "aa" only
194 ;; matches "alpha", while "ea" does not match any files.
196 ;; Regexp matching
197 ;; ---------------
199 ;; There is limited provision for regexp matching within ido,
200 ;; enabled through `ido-enable-regexp' (toggle with C-t).
201 ;; This allows you to type `[ch]$' for example and see all file names
202 ;; ending in `c' or `h'.
204 ;; Note: ido-style completion is inhibited when you enable regexp matching.
207 ;; Customization
208 ;; -------------
210 ;; Customize the `ido' group to change the `ido' functionality.
212 ;; To modify the keybindings, use the ido-setup-hook. For example:
213 ;;(add-hook 'ido-setup-hook 'ido-my-keys)
215 ;;(defun ido-my-keys ()
216 ;; "Add my keybindings for ido."
217 ;; (define-key ido-completion-map " " 'ido-next-match)
218 ;; )
220 ;; Seeing all the matching buffers or files
221 ;; ----------------------------------------
223 ;; If you have many matching files, they may not all fit onto one
224 ;; line of the minibuffer. Normally, the minibuffer window will grow
225 ;; to show you more of the matching files (depending on the setting
226 ;; of the variables `resize-mini-windows' and `max-mini-window-height').
227 ;; If you want ido to behave differently from the default minibuffer
228 ;; resizing behavior, set the variable `ido-max-window-height'.
230 ;; Also, to improve the responsiveness of ido, the maximum number of
231 ;; matching items is limited to 12, but you can increase or removed
232 ;; this limit via the `ido-max-prospects' variable.
234 ;; To see a full list of all matching buffers in a separate buffer,
235 ;; hit ? or press TAB when there are no further completions to the
236 ;; substring. Repeated TAB presses will scroll you through this
237 ;; separate buffer.
239 ;; Changing the list of files
240 ;; --------------------------
242 ;; By default, the list of current files is most recent first,
243 ;; oldest last, with the exception that the files visible in the
244 ;; current frame are put at the end of the list. A hook exists to
245 ;; allow other functions to order the list. For example, if you add:
247 ;; (add-hook 'ido-make-buffer-list-hook 'ido-summary-buffers-to-end)
249 ;; then all files matching "Summary" are moved to the end of the
250 ;; list. (I find this handy for keeping the INBOX Summary and so on
251 ;; out of the way.) It also moves files matching "output\*$" to the
252 ;; end of the list (these are created by AUCTeX when compiling.)
253 ;; Other functions could be made available which alter the list of
254 ;; matching files (either deleting or rearranging elements.)
256 ;; Highlighting
257 ;; ------------
259 ;; The highlighting of matching items is controlled via ido-use-faces.
260 ;; The faces used are ido-first-match, ido-only-match and
261 ;; ido-subdir.
262 ;; Colouring of the matching item was suggested by
263 ;; Carsten Dominik (dominik@strw.leidenuniv.nl).
265 ;; Replacement for read-buffer and read-file-name
266 ;; ----------------------------------------------
268 ;; ido-read-buffer and ido-read-file-name have been written to be drop
269 ;; in replacements for the normal buffer and file name reading
270 ;; functions `read-buffer' and `read-file-name'.
272 ;; To use ido for all buffer and file selections in Emacs, customize the
273 ;; variable `ido-everywhere'.
275 ;; Using ido-like behavior in other lisp packages
276 ;; -----------------------------------------------
278 ;; If you don't want to rely on the `ido-everywhere' functionality,
279 ;; ido-read-buffer, ido-read-file-name, and ido-read-directory-name
280 ;; can be used by other packages to read a buffer name, a file name,
281 ;; or a directory name in the `ido' way.
283 ;;; Acknowledgements
285 ;; Infinite amounts of gratitude goes to Stephen Eglen <stephen@cns.ed.ac.uk>
286 ;; who wrote iswitch-buffer mode - from which I ripped off 99% of the code
287 ;; for ido-switch-buffer and found the inspiration for ido-find-file.
288 ;; The ido package would never have existed without his work.
290 ;; Also thanks to Klaus Berndl, Rohit Namjoshi, Robert Fenk, Alex
291 ;; Schroeder, Bill Benedetto, Stephen Eglen, and many others for bug
292 ;; fixes and improvements.
294 ;;; History
296 ;; Since I discovered Stephen Eglen's excellent iswitchb package, I just
297 ;; couldn't live without it, but once being addicted to switching buffers
298 ;; with a minimum of keystrokes, I soon found that opening files in the
299 ;; old-fashioned way was just too slow - so I decided to write a package
300 ;; which could open files with the same speed and ease as iswitchb could
301 ;; switch buffers.
303 ;; I originally wrote a separate ifindf.el package based on a copy of
304 ;; iswitchb.el, which did for opening files what iswitchb did for
305 ;; switching buffers. Along the way, I corrected a few errors in
306 ;; ifindf which could have found its way back into iswitchb, but since
307 ;; most of the functionality of the two package was practically
308 ;; identical, I decided that the proper thing to do was to merge my
309 ;; ifindf package back into iswitchb.
311 ;; This is basically what ido (interactively do) is all about; but I
312 ;; found it ackward to merge my changes into the "iswitchb-" namespace,
313 ;; so I invented a common "ido-" namespace for the merged packages.
315 ;; This version is based on ido.el version 1.57 released on
316 ;; gnu.emacs.sources adapted for emacs 22.1 to use command remapping
317 ;; and optionally hooking the read-buffer and read-file-name functions.
319 ;; Prefix matching was added by Klaus Berndl <klaus.berndl@sdm.de> based on
320 ;; an idea of Yuji Minejima <ggb01164@nifty.ne.jp> and his mcomplete-package.
323 ;;; Code:

327 ;;; User Variables
329 ;; These are some things you might want to change.
