26 | ;;; Commentary: | |
27 | ;; | |
28 | ;; The speedbar provides a frame in which files, and locations in | |
29 | ;; files are displayed. These items can be clicked on with mouse-2 | |
30 | ;; in order to make the last active frame display that file location. | |
31 | ;; | |
32 | ;; Starting Speedbar: | |
33 | ;; | |
3a1aa597 GM |
34 | ;; Simply type `M-x speedbar', and it will be autoloaded for you. |
35 | ||
59588cd4 | 36 | ;; If you want to choose it from a menu, such as "Tools", you can do this: |
6b3eac8d | 37 | ;; |
6b3eac8d DN |
38 | ;; (define-key-after (lookup-key global-map [menu-bar tools]) |
39 | ;; [speedbar] '("Speedbar" . speedbar-frame-mode) [calendar]) | |
40 | ;; | |
6b3eac8d DN |
41 | ;; If you want to access speedbar using only the keyboard, do this: |
42 | ;; | |
3a1aa597 | 43 | ;; (global-set-key [f4] 'speedbar-get-focus) |
6b3eac8d DN |
44 | ;; |
45 | ;; This will let you hit f4 (or whatever key you choose) to jump | |
46 | ;; focus to the speedbar frame. Pressing it again will bring you back | |
47 | ;; to the attached frame. Pressing RET or e to jump to a file | |
48 | ;; or tag will move you back to the attached frame. The command | |
49 | ;; `speedbar-get-focus' will also create a speedbar frame if it does | |
50 | ;; not exist. | |
51 | ;; | |
52 | ;; Customizing Speedbar: | |
53 | ;; | |
54 | ;; Once a speedbar frame is active, it takes advantage of idle time | |
55 | ;; to keep its contents updated. The contents is usually a list of | |
56 | ;; files in the directory of the currently active buffer. When | |
57 | ;; applicable, tags in the active file can be expanded. | |
58 | ;; | |
59 | ;; To add new supported files types into speedbar, use the function | |
60 | ;; `speedbar-add-supported-extension' If speedbar complains that the | |
61 | ;; file type is not supported, that means there is no built in | |
62 | ;; support from imenu, and the etags part wasn't set up correctly. You | |
63 | ;; may add elements to `speedbar-supported-extension-expressions' as long | |
64 | ;; as it is done before speedbar is loaded. | |
65 | ;; | |
66 | ;; To prevent speedbar from following you into certain directories | |
67 | ;; use the function `speedbar-add-ignored-path-regexp' too add a new | |
68 | ;; regular expression matching a type of path. You may add list | |
69 | ;; elements to `speedbar-ignored-path-expressions' as long as it is | |
70 | ;; done before speedbar is loaded. | |
71 | ;; | |
72 | ;; To add new file types to imenu, see the documentation in the | |
59588cd4 | 73 | ;; file imenu.el that comes with Emacs. To add new file types which |
6b3eac8d DN |
74 | ;; etags supports, you need to modify the variable |
75 | ;; `speedbar-fetch-etags-parse-list'. | |
76 | ;; | |
77 | ;; If the updates are going too slow for you, modify the variable | |
78 | ;; `speedbar-update-speed' to a longer idle time before updates. | |
79 | ;; | |
80 | ;; If you navigate directories, you will probably notice that you | |
81 | ;; will navigate to a directory which is eventually replaced after | |
82 | ;; you go back to editing a file (unless you pull up a new file.) | |
83 | ;; The delay time before this happens is in | |
84 | ;; `speedbar-navigating-speed', and defaults to 10 seconds. | |
85 | ;; | |
59588cd4 KH |
86 | ;; To enable mouse tracking with information in the minibuffer of |
87 | ;; the attached frame, use the variable `speedbar-track-mouse-flag'. | |
88 | ;; | |
89 | ;; Tag layout can be modified through `speedbar-tag-hierarchy-method', | |
90 | ;; which controls how tags are layed out. It is actually a list of | |
91 | ;; functions that filter the data. The default groups large tag lists | |
92 | ;; into sub-lists. A long flat list can be used instead if needed. | |
93 | ;; Other filters could be easily added. | |
94 | ;; | |
6b3eac8d DN |
95 | ;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very |
96 | ;; well. Use the imenu keywords from tex-mode.el for better results. | |

59588cd4 | 100 | ;;; Developing for speedbar |
6b3eac8d | 101 | ;; |
59588cd4 | 102 | ;; Adding a speedbar specialized display mode: |
6b3eac8d | 103 | ;; |
59588cd4 KH |
104 | ;; Speedbar can be configured to create a special display for certain |
105 | ;; modes that do not display tradition file/tag data. Rmail, Info, | |
106 | ;; and the debugger are examples. These modes can, however, benefit | |
107 | ;; from a speedbar style display in their own way. | |
108 | ;; | |
109 | ;; If your `major-mode' is `foo-mode', the only requirement is to | |
110 | ;; create a function called `foo-speedbar-buttons' which takes one | |
111 | ;; argument, BUFFER. BUFFER will be the buffer speedbar wants filled. | |
112 | ;; In `foo-speedbar-buttons' there are several functions that make | |
113 | ;; building a speedbar display easy. See the documentation for | |
114 | ;; `speedbar-with-writable' (needed because the buffer is usually | |
115 | ;; read-only) `speedbar-make-tag-line', `speedbar-insert-button', and | |
116 | ;; `speedbar-insert-generic-list'. If you use | |
117 | ;; `speedbar-insert-generic-list', also read the doc for | |
118 | ;; `speedbar-tag-hierarchy-method' in case you wish to override it. | |
119 | ;; The function `speedbar-with-attached-buffer' brings you back to the | |
120 | ;; buffer speedbar is displaying for. | |
121 | ;; | |
122 | ;; For those functions that make buttons, the "function" should be a | |
123 | ;; symbol that is the function to call when clicked on. The "token" | |
124 | ;; is extra data you can pass along. The "function" must take three | |
125 | ;; parameters. They are (TEXT TOKEN INDENT). TEXT is the text of the | |
126 | ;; button clicked on. TOKEN is the data passed in when you create the | |
127 | ;; button. INDENT is an indentation level, or 0. You can store | |
128 | ;; indentation levels with `speedbar-make-tag-line' which creates a | |
129 | ;; line with an expander (eg. [+]) and a text button. | |
130 | ;; | |
131 | ;; Some useful functions when writing expand functions, and click | |
132 | ;; functions are `speedbar-change-expand-button-char', | |
133 | ;; `speedbar-delete-subblock', and `speedbar-center-buffer-smartly'. | |
134 | ;; The variable `speedbar-power-click' is set to t in your functions | |
135 | ;; when the user shift-clicks. This indications anything from | |
136 | ;; refreshing cached data to making a buffer appear in a new frame. | |
137 | ;; | |
138 | ;; If you wish to add to the default speedbar menu for the case of | |
139 | ;; `foo-mode', create a variable `foo-speedbar-menu-items'. This | |
140 | ;; should be a list compatible with the `easymenu' package. It will | |
141 | ;; be spliced into the main menu. (Available with click-mouse-3). If | |
142 | ;; you wish to have extra key bindings in your special mode, create a | |
143 | ;; variable `foo-speedbar-key-map'. Instead of using `make-keymap', | |
144 | ;; or `make-sparse-keymap', use the function | |
145 | ;; `speedbar-make-specialized-keymap'. This lets you inherit all of | |
146 | ;; speedbar's default bindings with low overhead. | |
147 | ;; | |
148 | ;; Adding a speedbar top-level display mode: | |
149 | ;; | |
150 | ;; Unlike the specialized modes, there are no name requirements, | |
151 | ;; however the methods for writing a button display, menu, and keymap | |
152 | ;; are the same. Once you create these items, you can call the | |
153 | ;; function `speedbar-add-expansion-list'. It takes one parameter | |
154 | ;; which is a list element of the form (NAME MENU KEYMAP &rest | |
155 | ;; BUTTON-FUNCTIONS). NAME is a string that will show up in the | |
156 | ;; Displays menu item. MENU is a symbol containing the menu items to | |
157 | ;; splice in. KEYMAP is a symbol holding the keymap to use, and | |
158 | ;; BUTTON-FUNCTIONS are the function names to call, in order, to create | |
159 | ;; the display. | |
39273816 KH |
160 | ;; Another tweekable variable is `speedbar-stealthy-function-list' |
161 | ;; which is of the form (NAME &rest FUNCTION ...). NAME is the string | |
162 | ;; name matching `speedbar-add-expansion-list'. (It does not need to | |
163 | ;; exist.). This provides additional display info which might be | |
164 | ;; time-consuming to calculate. | |
165 | ;; Lastly, `speedbar-mode-functions-list' allows you to set special | |
166 | ;; function overrides. At the moment very few functions are | |
167 | ;; over ridable, but more will be added as the need is discovered. | |
