30 | ;; for ido-switch-buffer and found the inspiration for ido-find-file. |
31 | ;; The ido package would never have existed without his work. | |

33 | ;; Also thanks to Klaus Berndl, Rohit Namjoshi, Robert Fenk, Alex Schroeder, | |

35 | ||
36 | ;;; History | |
37 | ||
38 | ;; Since I discovered Stephen Eglen's excellent iswitchb package, I just | |
39 | ;; couldn't live without it, but once being addicted to switching buffers | |
40 | ;; with a minimum of keystrokes, I soon found that opening files in the | |
41 | ;; old-fashioned way was just too slow - so I decided to write a package | |
42 | ;; which could open files with the same speed and ease as iswitchb could | |
43 | ;; switch buffers. | |
44 | ||
45 | ;; I originally wrote a separate ifindf.el package based on a copy of | |
46 | ;; iswitchb.el, which did for opening files what iswitchb did for | |
47 | ;; switching buffers. Along the way, I corrected a few errors in | |
48 | ;; ifindf which could have found its way back into iswitchb, but since | |
49 | ;; most of the functionality of the two package was practically | |
50 | ;; identical, I decided that the proper thing to do was to merge my | |
51 | ;; ifindf package back into iswitchb. | |
52 | ;; | |
53 | ;; This is basically what ido (interactively do) is all about; but I | |
54 | ;; found it ackward to merge my changes into the "iswitchb-" namespace, | |
55 | ;; so I invented a common "ido-" namespace for the merged packages. | |
56 | ;; | |
57 | ;; This version is based on ido.el version 1.57 released on | |
58 | ;; gnu.emacs.sources adapted for emacs 21.4 to use command remapping | |
59 | ;; and optionally hooking the read-buffer and read-file-name functions. | |
60 | ;; | |
61 | ;; Prefix matching was added by Klaus Berndl <klaus.berndl@sdm.de> based on | |
62 | ;; an idea of Yuji Minejima <ggb01164@nifty.ne.jp> and his mcomplete-package. | |
63 | ||
64 | ||
65 | ;;; Commentary: | |
66 | ||
67 | ;; Ido - interactive do - switches between buffers and opens files and | |
68 | ;; directories with a minimum of keystrokes. It is a superset of | |
69 | ;; iswitchb, the interactive buffer switching package by Stephen Eglen. | |
70 | ||
71 | ;; Interactive substring matching | |
72 | ;; ------------------------------ | |
73 | ;; | |
74 | ;; As you type in a substring, the list of buffers or files currently | |
75 | ;; matching the substring are displayed as you type. The list is | |
76 | ;; ordered so that the most recent buffers or files visited come at | |
77 | ;; the start of the list. | |
78 | ;; | |
79 | ;; The buffer or file at the start of the list will be the one visited | |
80 | ;; when you press RETURN. By typing more of the substring, the list is | |
81 | ;; narrowed down so that gradually the buffer or file you want will be | |
82 | ;; at the top of the list. Alternatively, you can use C-s and C-r (or | |
83 | ;; the right and left arrow keys) to rotate buffer or file names in the | |
84 | ;; list until the one you want is at the top of the list. | |
85 | ;; | |
86 | ;; Completion is also available so that you can see what is common to | |
87 | ;; all of the matching buffers or files as you type. | |
88 | ;; | |
89 | ;; Example: | |
90 | ;; | |
91 | ;; If I have two buffers called "123456" and "123", with "123456" the | |
92 | ;; most recent, when I use ido-switch-buffer, I first of all get | |
93 | ;; presented with the list of all the buffers | |
94 | ;; | |
71296446 | 95 | ;; Buffer: {123456,123} |
789d1bf0 KS |
96 | ;; |
97 | ;; If I then press 2: | |
98 | ;; Buffer: 2[3]{123456,123} | |
99 | ;; | |
100 | ;; The list in {...} are the matching buffers, most recent first | |
101 | ;; (buffers visible in the current frame are put at the end of the | |
102 | ;; list by default). At any time I can select the item at the head of | |
103 | ;; the list by pressing RET. I can also bring the put the first | |
104 | ;; element at the end of the list by pressing C-s or [right], or put | |
105 | ;; the last element at the head of the list by pressing C-r or [left]. | |
106 | ;; | |
107 | ;; The item in [...] indicates what can be added to my input by | |
108 | ;; pressing TAB. In this case, I will get "3" added to my input. | |
109 | ||
110 | ;; So, I press TAB: | |
111 | ;; Buffer: 23{123456,123} | |
112 | ;; | |
113 | ;; At this point, I still have two matching buffers. | |
114 | ;; If I want the first buffer in the list, I simply press RET. If I | |
115 | ;; wanted the second in the list, I could press C-s to move it to the | |
116 | ;; top of the list and then RET to select it. | |
117 | ;; | |
118 | ;; However, if I type 4, I only have one match left: | |
119 | ;; Buffer: 234[123456] [Matched] | |
120 | ;; | |
121 | ;; Since there is only one matching buffer left, it is given in [] and we | |
122 | ;; see the text [Matched] afterwards. I can now press TAB or RET to go | |
123 | ;; to that buffer. | |
124 | ;; | |
125 | ;; If however, I now type "a": | |
126 | ;; Buffer: 234a [No match] | |
127 | ;; There are no matching buffers. If I press RET or TAB, I can be | |
128 | ;; prompted to create a new buffer called "234a". | |
129 | ;; | |
130 | ;; Of course, where this function comes in really useful is when you | |
131 | ;; can specify the buffer using only a few keystrokes. In the above | |
132 | ;; example, the quickest way to get to the "123456" file would be | |
133 | ;; just to type 4 and then RET (assuming there isn't any newer buffer | |
134 | ;; with 4 in its name). | |
135 | ||
136 | ;; Likewise, if you use C-x C-f (ido-find-file), the list of files and | |
137 | ;; directories in the current directory is provided in the same | |
138 | ;; fashion as the buffers above. The files and directories are | |
139 | ;; normally sorted in alphabetical order, but the most recently | |
140 | ;; visited directory is placed first to speed up navigating to | |
141 | ;; directories that you have visited recently. | |
142 | ;; | |
143 | ;; In addition to scrolling through the list using [right] and [left], | |
144 | ;; you can use [up] and [down] to quickly scroll the list to the next | |
145 | ;; or previous subdirectory. | |
146 | ;; | |
147 | ;; To go down into a subdirectory, and continue the file selection on | |
148 | ;; the files in that directory, simply move the directory to the head | |
149 | ;; of the list and hit RET. | |
150 | ;; | |
151 | ;; To go up to the parent directory, delete any partial file name | |
152 | ;; already specified (e.g. using [backspace]) and hit [backspace]. | |
153 | ;; | |
154 | ;; To go to the root directory (on the current drive), enter two | |
155 | ;; slashes. On MS-DOS or Windows, to select the root of another | |
156 | ;; drive, enter X:/ where X is the drive letter. You can also visit | |
157 | ;; files on other hosts using the ange-ftp notations `/host:' and | |
158 | ;; `/user@host:'. See the variable `ido-slow-ftp-hosts' if you want | |
71296446 | 159 | ;; to inhibit the ido substring matching for ftp access. |
789d1bf0 KS |
160 | ;; |
161 | ;; If for some reason you cannot specify the proper file using | |
162 | ;; ido-find-file, you can press C-f to enter the normal find-file. | |
163 | ;; You can also press C-b to drop into ido-switch-buffer. | |
164 | ||
165 | ;; See the doc string of ido-switch-buffer and ido-find-file for full | |
166 | ;; keybindings and features. | |
167 | ;; (describe-function 'ido-find-file) | |
168 | ||
169 | ;; Hidden buffers and files | |
170 | ;; ------------------------ | |
171 | ;; | |
172 | ;; Normally, ido does not include hidden buffers (whose name starts | |
173 | ;; with a space) and hidden files and directories (whose name starts | |
174 | ;; with `.') in the list of possible completions. However, if the | |
175 | ;; substring you enter does not match any of the visible buffers or | |
176 | ;; files, ido will automatically look for completions among the hidden | |
177 | ;; buffers or files. | |
178 | ;; | |
179 | ;; You can toggle display of the hidden buffers and files with C-a. | |
180 | ||
181 | ;; Additional functionality | |
182 | ;; ------------------------ | |
183 | ;; | |
184 | ;; After C-x b, the buffer at the head of the list can be killed by | |
185 | ;; pressing C-k. If the buffer needs saving, you will be queried | |
186 | ;; before the buffer is killed. | |
187 | ;; | |
188 | ;; Likewise, after C-x C-f, you can delete (i.e. physically remove) | |
189 | ;; the file at the head of the list with C-k. You will always be | |
190 | ;; asked for confirmation before the file is deleted. | |
191 | ;; | |
192 | ;; If you enter C-x b to switch to a buffer visiting a given file, and | |
193 | ;; you find that the file you are after is not in any buffer, you can | |
194 | ;; press C-f to immediately drop into ido-find-file. And you can | |
195 | ;; switch back to buffer selection with C-b. | |
196 | ||
197 | ;; Prefix matching | |
198 | ;; --------------- | |
199 | ;; | |
200 | ;; The standard way of completion with Unix-shells and Emacs is to insert a | |
201 | ;; PREFIX and then hitting TAB (or another completion key). Cause of this | |
202 | ;; behavior has become second nature to a lot of emacs users `ido' offers in | |
203 | ;; addition to the default substring-matching-method (look above) also the | |
204 | ;; prefix-matching-method. The kind of matching is the only difference to | |
205 | ;; the description of the substring-matching above. | |
206 | ;; | |
207 | ;; You can toggle prefix matching with C-p. | |
208 | ;; | |
209 | ;; Example: | |
210 | ;; | |
211 | ;; If you have again two Buffers "123456" and "123" then hitting "2" does | |
212 | ;; not match because "2" is not a PREFIX in any of the buffer-names. This | |
213 | ;; is the only difference between the substring and prefix matching. | |
214 | ||
215 | ;; Flexible matching | |
216 | ;; ----------------- | |
217 | ;; | |
218 | ;; If you set ido-enable-flex-matching, ido will do a more flexible | |
219 | ;; matching (unless regexp matching is active) to find possible matches | |
220 | ;; among the available buffer or file names if no matches are found using | |
221 | ;; the normal prefix or substring matching. | |
222 | ;; | |
223 | ;; The flexible matching implies that any item which simply contains all | |
224 | ;; of the entered characters in the specified sequence will match. | |
225 | ;; | |
226 | ;; Example: | |
227 | ;; | |
228 | ;; If you have four files "alpha", "beta", "gamma", and "delta", | |
229 | ;; entering "aa" will match "alpha" and "gamma", while "ea" matches | |
230 | ;; "beta" and "delta". If prefix matching is also active, "aa" only | |
231 | ;; matches "alpha", while "ea" does not match any files. | |
232 | ||
233 | ;; Regexp matching | |
234 | ;; --------------- | |
235 | ;; | |
236 | ;; There is limited provision for regexp matching within ido, | |
237 | ;; enabled through `ido-enable-regexp' (toggle with C-t). | |
238 | ;; This allows you to type `c$' for example and see all file names | |
239 | ;; ending in `c'. This facility is quite limited though in two | |
240 | ;; respects. First, you can't currently type in expressions like | |
241 | ;; `[0-9]' directly -- you have to type them in when ido-enable-regexp | |
242 | ;; is nil and then toggle on the regexp functionality. Likewise, | |
243 | ;; don't enter an expression containing `\' in regexp mode. If you | |
244 | ;; try, ido gets confused, so just hit C-g and try again. Secondly, | |
245 | ;; no completion mechanism is currently offered with regexp searching. | |
246 | ||
247 | ||
248 | ;; Customization | |
249 | ;; ------------- | |
250 | ;; | |
251 | ;; Customize the `ido' group to change the `ido' functionality. | |
252 | ;; | |
253 | ;; To modify the keybindings, use the hook provided. For example: | |
254 | ;;(add-hook 'ido-define-mode-map-hook 'ido-my-keys) | |
255 | ;; | |
256 | ;;(defun ido-my-keys () | |
257 | ;; "Add my keybindings for ido." | |
258 | ;; (define-key ido-mode-map " " 'ido-next-match) | |
259 | ;; ) | |
260 | ||
261 | ;; Seeing all the matching buffers or files | |
262 | ;; ---------------------------------------- | |
263 | ;; | |
264 | ;; If you have many matching files, they may not all fit onto one | |
265 | ;; line of the minibuffer. Normally, the minibuffer window will grow | |
266 | ;; to show you more of the matching files (depending on the setting | |
267 | ;; of the variables `resize-mini-windows' and `max-mini-window-height'). | |
268 | ;; If you want ido to behave differently from the default minibuffer | |
269 | ;; resizing behaviour, set the variable `ido-max-window-height'. | |
270 | ;; | |
271 | ;; Also, to improve the responsiveness of ido, the maximum number of | |
272 | ;; matching items is limited to 12, but you can increase or removed | |
273 | ;; this limit via the `ido-max-prospects' variable. | |
274 | ||
275 | ;; To see a full list of all matching buffers in a separate buffer, | |
276 | ;; hit ? or press TAB when there are no further completions to the | |
277 | ;; substring. Repeated TAB presses will scroll you through this | |
278 | ;; separate buffer. | |
279 | ||
280 | ;; Changing the list of files | |
281 | ;; -------------------------- | |
282 | ||
283 | ;; By default, the list of current files is most recent first, | |
284 | ;; oldest last, with the exception that the files visible in the | |
285 | ;; current frame are put at the end of the list. A hook exists to | |
286 | ;; allow other functions to order the list. For example, if you add: | |
287 | ;; | |
288 | ;; (add-hook 'ido-make-buffer-list-hook 'ido-summary-buffers-to-end) | |
289 | ;; | |
290 | ;; then all files matching "Summary" are moved to the end of the | |
291 | ;; list. (I find this handy for keeping the INBOX Summary and so on | |
292 | ;; out of the way.) It also moves files matching "output\*$" to the | |
293 | ;; end of the list (these are created by AUC TeX when compiling.) | |
294 | ;; Other functions could be made available which alter the list of | |
295 | ;; matching files (either deleting or rearranging elements.) | |
296 | ||
297 | ;; Highlighting | |
298 | ;; ------------ | |
299 | ||
300 | ;; The highlighting of matching items is controlled via ido-use-faces. | |
301 | ;; The faces used are ido-first-match-face, ido-only-match-face and | |
302 | ;; ido-subdir-face. | |
303 | ;; Colouring of the matching item was suggested by | |
304 | ;; Carsten Dominik (dominik@strw.leidenuniv.nl). | |
305 | ||
306 | ;; Replacement for read-buffer and read-file-name | |
307 | ;; ---------------------------------------------- | |
308 | ||
309 | ;; ido-read-buffer and ido-read-file-name have been written to be drop | |
310 | ;; in replacements for the normal buffer and file name reading | |
311 | ;; functions `read-buffer' and `read-file-name'. | |
312 | ||
313 | ;; To use ido for all buffer and file selections in Emacs, customize the | |
314 | ;; variable `ido-everywhere'. | |
315 | ||
316 | ;; Using ido-like behaviour in other lisp packages | |
317 | ;; ----------------------------------------------- | |
318 | ||
319 | ;; If you don't want to rely on the `ido-everywhere' functionality, | |
320 | ;; ido-read-buffer, ido-read-file-name, and ido-read-directory-name | |
321 | ;; can be used by other packages to read a buffer name, a file name, | |
322 | ;; or a directory name in the `ido' way. | |
