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