27 ;;; Installation:
29 ;; To get the functions in this package bound to keys, do
30 ;; (iswitchb-default-keybindings)
32 ;;; Commentary:
34 ;; As you type in a substring, the list of buffers currently matching
35 ;; the substring are displayed as you type. The list is ordered so
36 ;; that the most recent buffers visited come at the start of the list.
37 ;; The buffer at the start of the list will be the one visited when
38 ;; you press return. By typing more of the substring, the list is
39 ;; narrowed down so that gradually the buffer you want will be at the
40 ;; top of the list. Alternatively, you can use C-s an C-r to rotate
41 ;; buffer names in the list until the one you want is at the top of
42 ;; the list. Completion is also available so that you can see what is
43 ;; common to all of the matching buffers as you type.
45 ;; This code is similar to a couple of other packages. Michael R Cook
46 ;; <mcook@cognex.com wrote a similar buffer switching package, but
47 ;; does exact matching rather than substring matching on buffer names.
48 ;; I also modified a couple of functions from icomplete.el to provide
49 ;; the completion feedback in the minibuffer.
51 ;;; Example
53 ;;If I have two buffers called "123456" and "123", with "123456" the
54 ;;most recent, when I use iswitchb, I first of all get presented with
55 ;;the default buffer (xxx) to switch to:
56 ;;
57 ;; iswitch {default xxx}
58 ;;
59 ;; If I then press 2:
60 ;; iswitch 2[3]{123456,123}
61 ;;
62 ;; The list in {} are the matching buffers, most recent first (buffers
63 ;; visible in the current frame are put at the end of the list by
64 ;; default). At any time I can select the item at the head of the
65 ;; list by pressing RET. I can also bring the put the first element
66 ;; at the end of the list by pressing C-s, or put the last element at
67 ;; the head of the list by pressing C-r. The item in [] indicates
68 ;; what can be added to my input by pressing TAB. In this case, I
69 ;; will get "3" added to my input. So, press TAB:
70 ;; iswitch 23{123456,123}
71 ;;
72 ;; At this point, I still have two matching buffers.
73 ;; If I want the first buffer in the list, I simply press RET. If I
74 ;; wanted the second in the list, I could press C-s to move it to the
75 ;; top of the list and then RET to select it.
76 ;;
77 ;;However, If I type 4, I only have one match left:
78 ;; iswitch 234[123456] [Matched]
79 ;;
80 ;;Since there is only one matching buffer left, it is given in [] and we
81 ;;see the text [Matched] afterwards. I can now press TAB or RET to go
82 ;;to that buffer.
83 ;;
84 ;; If however, I now type "a":
85 ;; iswitch 234a [No match]
86 ;; There are no matching buffers. If I press RET or TAB, I can be
87 ;; prompted to create a new buffer called "234a".
88 ;;
89 ;; Of course, where this function comes in really useful is when you
90 ;; can specify the buffer using only a few keystrokes. In the above
91 ;; example, the quickest way to get to the "123456" buffer would be
92 ;; just to type 4 and then RET (assuming there isnt any newer buffer
93 ;; with 4 in its name).
95 ;; To see a full list of all matching buffers in a separate buffer,
96 ;; hit ? or press TAB when there are no further completions to the
97 ;; substring.
99 ;;
100 ;; See the doc string of iswitchb for full keybindings and features.
101 ;; (describe-function 'iswitchb)
103 ;;; Customisation
105 ;; See the User Variables section below for easy ways to change the
106 ;; functionality of the program.
107 ;; To modify the keybindings, use the hook provided. For example:
108 ;;(add-hook 'iswitchb-define-mode-map-hook
109 ;; 'iswitchb-my-keys)
110 ;;
111 ;;(defun iswitchb-my-keys ()
112 ;; "Add my keybings for iswitchb."
113 ;; (define-key iswitchb-mode-map " " 'iswitchb-next-match)
114 ;; )
115 ;;
116 ;; Seeing all the matching buffers.
117 ;; If you have many matching buffers, they may not all fit onto one
118 ;; line of the minibuffer. In this case, you should use rsz-mini
119 ;; (resize-minibuffer-mode). You can also limit iswitchb so that it
120 ;; only shows a certain number of lines -- see the documentation for
121 ;; `iswitchb-minibuffer-setup-hook'.
124 ;; Changing the list of buffers.
126 ;; By default, the list of current buffers is most recent first,
127 ;; oldest last, with the exception that the buffers visible in the
128 ;; current frame are put at the end of the list. A hook exists to
129 ;; allow other functions to order the list. For example, if you add:
130 ;;
131 ;; (add-hook 'iswitchb-make-buflist-hook 'iswitchb-summaries-to-end)
132 ;;
133 ;; then all buffers matching "Summary" are moved to the end of the
134 ;; list. (I find this handy for keeping the INBOX Summary and so on
135 ;; out of the way.) It also moves buffers matching "output\*$" to the
136 ;; end of the list (these are created by AUC TeX when compiling.)
137 ;; Other functions could be made available which alter the list of
138 ;; matching buffers (either deleting or rearranging elements.)
140 ;; Font-Lock
142 ;; If you have font-lock loaded, the first matching buffer is
143 ;; highlighted. To switch this off, set (setq iswitchb-use-fonts nil)
144 ;; I don't use font-lock that much, so I've hardcoded the faces. If
145 ;; this is too harsh, let me know. Colouring of the matching buffer
146 ;; name was suggested by Carsten Dominik (dominik@strw.leidenuniv.nl)
148 ;;; Comparison with iswitch-buffer
150 ;; This package is a rewrite of iswitch-buffer, using the minibuffer
151 ;; rather than the echo area. The advantages of using the minibuffer
152 ;; are several:
153 ;; o minibuffer has more powerful editing facilities
154 ;; o doesnt interfere with other packages that use the echo area
155 ;; o *Messages* buffer doesnt get filled up with all of the messages that
156 ;; go to the modeline
157 ;; o cursor is in the minibuffer, which somehow looks right.
158 ;; o minibuffer can be resized dynamically to show all the possible matching
159 ;; buffers rather than just the first line's worth (using rsz-mini).
160 ;;
161 ;; Disadvantages:
162 ;; o cant change the prompt to indicate status of searching (eg whether
163 ;; regexp searching is currently on).
166 ;;; Acknowledgements

247 ;; In Xemacs, the default buffer is not shown the first time you enter
248 ; the minibuffer, but if you type a char and then delete a char, the
249 ; default appears. The first time we enter the minibuffer in XEmacs,
250 ; the default msg is not displayed, presumably because the hook is not
251 ; being called. I have put in a temporary hack therefore at the
252 ; bottom of this file.
253 ;
254 ; There is also a problem with the backspace key in XEmacs, so I have
255 ; bound it to the normal backward-delete-char.
