| 31 | ;; Interactive substring matching |
| 32 | ;; ------------------------------ |
| 33 | ;; |
| 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. |
| 38 | ;; |
| 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. |
| 45 | ;; |
| 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. |
| 48 | ;; |
| 49 | ;; Example: |
| 50 | ;; |
| 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 |
| 54 | ;; |
| 55 | ;; Buffer: {123456 | 123} |
| 56 | ;; |
| 57 | ;; If I then press 2: |
| 58 | ;; Buffer: 2[3]{123456 | 123} |
| 59 | ;; |
| 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]. |
| 66 | ;; |
| 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. |
| 69 | |
| 70 | ;; So, I press TAB: |
| 71 | ;; Buffer: 23{123456 | 123} |
| 72 | ;; |
| 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. |
| 77 | ;; |
| 78 | ;; However, if I type 4, I only have one match left: |
| 79 | ;; Buffer: 234[123456] |
| 80 | ;; |
| 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. |
| 84 | ;; |
| 85 | ;; If I want to create a new buffer named "234", I press C-j instead of |
| 86 | ;; TAB or RET. |
| 87 | ;; |
| 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". |
| 92 | ;; |
| 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). |
| 98 | |
| 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. |
| 105 | ;; |
| 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. |
| 109 | ;; |
| 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. |
| 113 | ;; |
| 114 | ;; To go up to the parent directory, delete any partial file name |
| 115 | ;; already specified (e.g. using [backspace]) and hit [backspace]. |
| 116 | ;; |
| 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. |
| 123 | ;; |
| 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. |
| 127 | |
| 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) |
| 131 | |
| 132 | ;; Hidden buffers and files |
| 133 | ;; ------------------------ |
| 134 | ;; |
| 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. |
| 141 | ;; |
| 142 | ;; You can toggle display of the hidden buffers and files with C-a. |
| 143 | |
| 144 | ;; Additional functionality |
| 145 | ;; ------------------------ |
| 146 | ;; |
| 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. |
| 150 | ;; |
| 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. |
| 154 | ;; |
| 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. |
| 159 | |
| 160 | ;; Prefix matching |
| 161 | ;; --------------- |
| 162 | ;; |
| 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. |
| 169 | ;; |
| 170 | ;; You can toggle prefix matching with C-p. |
| 171 | ;; |
| 172 | ;; Example: |
| 173 | ;; |
| 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. |
| 176 | |
| 177 | ;; Flexible matching |
| 178 | ;; ----------------- |
| 179 | ;; |
| 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. |
| 184 | ;; |
| 185 | ;; The flexible matching implies that any item which simply contains all |
| 186 | ;; of the entered characters in the specified sequence will match. |
| 187 | ;; |
| 188 | ;; Example: |
| 189 | ;; |
| 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. |
| 194 | |
| 195 | ;; Regexp matching |
| 196 | ;; --------------- |
| 197 | ;; |
| 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'. |
| 202 | ;; |
| 203 | ;; Note: ido-style completion is inhibited when you enable regexp matching. |
| 204 | |
| 205 | |
| 206 | ;; Customization |
| 207 | ;; ------------- |
| 208 | ;; |
| 209 | ;; Customize the `ido' group to change the `ido' functionality. |
| 210 | ;; |
| 211 | ;; To modify the keybindings, use the ido-setup-hook. For example: |
| 212 | ;;(add-hook 'ido-setup-hook 'ido-my-keys) |
| 213 | ;; |
| 214 | ;;(defun ido-my-keys () |
| 215 | ;; "Add my keybindings for ido." |
| 216 | ;; (define-key ido-completion-map " " 'ido-next-match) |
| 217 | ;; ) |
| 218 | |
| 219 | ;; Seeing all the matching buffers or files |
| 220 | ;; ---------------------------------------- |
| 221 | ;; |
| 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'. |
| 228 | ;; |
| 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. |
| 232 | |
| 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. |
| 237 | |
| 238 | ;; Changing the list of files |
| 239 | ;; -------------------------- |
| 240 | |
| 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: |
| 245 | ;; |
| 246 | ;; (add-hook 'ido-make-buffer-list-hook 'ido-summary-buffers-to-end) |
| 247 | ;; |
| 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.) |
| 254 | |
| 255 | ;; Highlighting |
| 256 | ;; ------------ |
| 257 | |
| 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). |
| 263 | |
| 264 | ;; Replacement for read-buffer and read-file-name |
| 265 | ;; ---------------------------------------------- |
| 266 | |
| 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'. |
| 270 | |
| 271 | ;; To use ido for all buffer and file selections in Emacs, customize the |
| 272 | ;; variable `ido-everywhere'. |
| 273 | |
| 274 | ;; Using ido-like behavior in other lisp packages |
| 275 | ;; ----------------------------------------------- |
| 276 | |
| 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. |
| 281 | |
| 282 | ;;; Acknowledgements |
| 283 | |
| 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. |
| 288 | |
| 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. |
| 292 | |
| 293 | ;;; History |
| 294 | |
| 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. |
| 301 | |
| 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. |
| 309 | ;; |
| 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. |
| 313 | ;; |
| 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. |
| 317 | ;; |
| 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. |
