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 | ;; | |
34 | ;; If speedbar came to you as a part of Emacs, simply type | |
35 | ;; `M-x speedbar', and it will be autoloaded for you. A "Speedbar" | |
36 | ;; submenu will be added under "Tools". | |
37 | ;; | |
38 | ;; If speedbar is not a part of your distribution, then add | |
39 | ;; this to your .emacs file: | |
40 | ;; | |
41 | ;; (autoload 'speedbar-frame-mode "speedbar" "Popup a speedbar frame" t) | |
42 | ;; (autoload 'speedbar-get-focus "speedbar" "Jump to speedbar frame" t) | |
43 | ;; | |
44 | ;; If you want to choose it from a menu, you can do this: | |
45 | ;; | |
46 | ;; Emacs: | |
47 | ;; (define-key-after (lookup-key global-map [menu-bar tools]) | |
48 | ;; [speedbar] '("Speedbar" . speedbar-frame-mode) [calendar]) | |
49 | ;; | |
50 | ;; XEmacs: | |
51 | ;; (add-menu-button '("Tools") | |
52 | ;; ["Speedbar" speedbar-frame-mode | |
53 | ;; :style toggle | |
54 | ;; :selected (and (boundp 'speedbar-frame) | |
55 | ;; (frame-live-p speedbar-frame) | |
56 | ;; (frame-visible-p speedbar-frame))] | |
57 | ;; "--") | |
58 | ;; | |
59 | ;; If you want to access speedbar using only the keyboard, do this: | |
60 | ;; | |
61 | ;; (global-set-key [(f4)] 'speedbar-get-focus) | |
62 | ;; | |
63 | ;; This will let you hit f4 (or whatever key you choose) to jump | |
64 | ;; focus to the speedbar frame. Pressing it again will bring you back | |
65 | ;; to the attached frame. Pressing RET or e to jump to a file | |
66 | ;; or tag will move you back to the attached frame. The command | |
67 | ;; `speedbar-get-focus' will also create a speedbar frame if it does | |
68 | ;; not exist. | |
69 | ;; | |
70 | ;; Customizing Speedbar: | |
71 | ;; | |
72 | ;; Once a speedbar frame is active, it takes advantage of idle time | |
73 | ;; to keep its contents updated. The contents is usually a list of | |
74 | ;; files in the directory of the currently active buffer. When | |
75 | ;; applicable, tags in the active file can be expanded. | |
76 | ;; | |
77 | ;; To add new supported files types into speedbar, use the function | |
78 | ;; `speedbar-add-supported-extension' If speedbar complains that the | |
79 | ;; file type is not supported, that means there is no built in | |
80 | ;; support from imenu, and the etags part wasn't set up correctly. You | |
81 | ;; may add elements to `speedbar-supported-extension-expressions' as long | |
82 | ;; as it is done before speedbar is loaded. | |
83 | ;; | |
84 | ;; To prevent speedbar from following you into certain directories | |
85 | ;; use the function `speedbar-add-ignored-path-regexp' too add a new | |
86 | ;; regular expression matching a type of path. You may add list | |
87 | ;; elements to `speedbar-ignored-path-expressions' as long as it is | |
88 | ;; done before speedbar is loaded. | |
89 | ;; | |
90 | ;; To add new file types to imenu, see the documentation in the | |
91 | ;; file imenu.el that comes with emacs. To add new file types which | |
92 | ;; etags supports, you need to modify the variable | |
93 | ;; `speedbar-fetch-etags-parse-list'. | |
94 | ;; | |
95 | ;; If the updates are going too slow for you, modify the variable | |
96 | ;; `speedbar-update-speed' to a longer idle time before updates. | |
97 | ;; | |
98 | ;; If you navigate directories, you will probably notice that you | |
99 | ;; will navigate to a directory which is eventually replaced after | |
100 | ;; you go back to editing a file (unless you pull up a new file.) | |
101 | ;; The delay time before this happens is in | |
102 | ;; `speedbar-navigating-speed', and defaults to 10 seconds. | |
103 | ;; | |
104 | ;; Users XEmacs previous to 20 may want to change the default | |
105 | ;; timeouts for `speedbar-update-speed' to something longer as XEmacs | |
106 | ;; doesn't have idle timers, the speedbar timer keeps going off | |
107 | ;; arbitrarily while you're typing. It's quite pesky. | |
108 | ;; | |
109 | ;; Users of really old emacsen without the needed timers will not | |
110 | ;; have speedbar updating automatically. Use "r" to refresh the | |
111 | ;; display after changing directories. Remember, do not interrupt the | |
112 | ;; stealthy updates or your display may not be completely refreshed. | |
113 | ;; | |
114 | ;; See optional file `speedbspec.el' for additional configurations | |
115 | ;; which allow speedbar to create specialized lists for special modes | |
116 | ;; that are not file-related. | |
117 | ;; | |
118 | ;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very | |
119 | ;; well. Use the imenu keywords from tex-mode.el for better results. | |
120 | ;; | |
121 | ;; This file requires the library package assoc (association lists) | |
122 | ;; and the package custom (for easy configuration of speedbar) | |
123 | ;; http://www.dina.kvl.dk/~abraham/custom/ | |
124 | ;; | |
125 | ;; If you do not have custom installed, you can still get face colors | |
126 | ;; by modifying the faces directly in your .emacs file, or setting | |
127 | ;; them in your .Xdefaults file. | |
128 | ;; Here is an example .Xdefaults for a dark background: | |
129 | ;; | |
130 | ;; emacs*speedbar-button-face.attributeForeground: Aquamarine | |
131 | ;; emacs*speedbar-selected-face.attributeForeground: red | |
132 | ;; emacs*speedbar-selected-face.attributeUnderline: true | |
133 | ;; emacs*speedbar-directory-face.attributeForeground: magenta | |
134 | ;; emacs*speedbar-file-face.attributeForeground: green3 | |
135 | ;; emacs*speedbar-highlight-face.attributeBackground: sea green | |
136 | ;; emacs*speedbar-tag-face.attributeForeground: yellow | |

142 | ;;; Change log: | |
143 | ;; 0.1 Initial Revision | |
144 | ;; 0.2 Fixed problem with x-pointer-shape causing future frames not | |
145 | ;; to be created. | |
146 | ;; Fixed annoying habit of `speedbar-update-contents' to make | |
147 | ;; it possible to accidentally kill the speedbar buffer. | |
148 | ;; Clicking directory names now only changes the contents of | |
149 | ;; the speedbar, and does not cause a dired mode to appear. | |
150 | ;; Clicking the <+> next to the directory does cause dired to | |
151 | ;; be run. | |
152 | ;; Added XEmacs support, which means timer support moved to a | |
153 | ;; platform independant call. | |
154 | ;; Added imenu support. Now modes are supported by imenu | |
155 | ;; first, and etags only if the imenu call doesn't work. | |
156 | ;; Imenu is a little faster than etags, and is more emacs | |
157 | ;; friendly. | |
158 | ;; Added more user control variables described in the commentary. | |
159 | ;; Added smart recentering when nodes are opened and closed. | |
160 | ;; 0.3 x-pointer-shape fixed for emacs 19.35, so I put that check in. | |
161 | ;; Added invisible codes to the beginning of each line. | |
162 | ;; Added list aproach to node expansion for easier addition of new | |
163 | ;; types of things to expand by | |
164 | ;; Added multi-level path name support | |
165 | ;; Added multi-level tag name support. | |
166 | ;; Only mouse-2 is now used for node expansion | |
167 | ;; Added keys e + - to edit expand, and contract node lines | |
168 | ;; Added longer legal file regexp for all those modes which support | |
169 | ;; imenu. (pascal, fortran90, ada, pearl) | |
170 | ;; Added pascal support to etags from Dave Penkler <dave_penkler@grenoble.hp.com> | |
171 | ;; Fixed centering algorithm | |
172 | ;; Tried to choose background independent colors. Made more robust. | |
173 | ;; Rearranged code into a more logical order | |
174 | ;; 0.3.1 Fixed doc & broken keybindings | |
175 | ;; Added mode hooks. | |
176 | ;; Improved color selection to be background mode smart | |
177 | ;; `nil' passed to `speedbar-frame-mode' now toggles the frame as | |
178 | ;; advertised in the doc string | |
179 | ;; 0.4a Added modified patch from Dan Schmidt <dfan@lglass.com> allowing a | |
180 | ;; directory cache to be maintained speeding up revisiting of files. | |
181 | ;; Default raise-lower behavior is now off by default. | |
182 | ;; Added some menu items for edit expand and contract. | |
183 | ;; Pre 19.31 emacsen can run without idle timers. | |
184 | ;; Added some patch information from Farzin Guilak <farzin@protocol.com> | |
185 | ;; adding xemacs specifics, and some etags upgrades. | |
186 | ;; Added ability to set a faces symbol-value to a string | |
187 | ;; representing the desired foreground color. (idea from | |
188 | ;; Farzin Guilak, but implemented differently) | |
189 | ;; Fixed problem with 1 character buttons. | |
190 | ;; Added support for new Imenu marker technique. | |
191 | ;; Added `speedbar-load-hooks' for things to run only once on | |
192 | ;; load such as updating one of the many lists. | |
193 | ;; Added `speedbar-supported-extension-expressions' which is a | |
194 | ;; list of extensions that speedbar will tag. This variable | |
195 | ;; should only be updated with `speedbar-add-supported-extension' | |
196 | ;; Moved configure dialog support to a separate file so | |
197 | ;; speedbar is not dependant on eieio to run | |
198 | ;; Fixed list-contraction problem when the item was at the end | |
199 | ;; of a sublist. | |
200 | ;; Fixed XEmacs multi-frame timer selecting bug problem. | |
201 | ;; Added `speedbar-ignored-modes' which is a list of major modes | |
202 | ;; speedbar will not follow when it is displayed in the selected frame | |
203 | ;; 0.4 When the file being edited is not in the list, and is a file | |
204 | ;; that should be in the list, the speedbar cache is replaced. | |
205 | ;; Temp buffers are now shown in the attached frame not the | |
206 | ;; speedbar frame | |
207 | ;; New variables `speedbar-vc-*' and `speedbar-stealthy-function-list' | |
208 | ;; added. `speedbar-update-current-file' is now a member of | |
209 | ;; the stealthy list. New function `speedbar-check-vc' will | |
210 | ;; examine each file and mark it if it is checked out. To | |
211 | ;; add new version control types, override the function | |
212 | ;; `speedbar-this-file-in-vc' and `speedbar-vc-check-dir-p'. | |
213 | ;; The stealth list is interruptible so that long operations | |
214 | ;; do not interrupt someones editing flow. Other long | |
215 | ;; speedbar updates will be added to the stealthy list in the | |
216 | ;; future should interesting ones be needed. | |
217 | ;; Added many new functions including: | |
218 | ;; `speedbar-item-byte-compile' `speedbar-item-load' | |
219 | ;; `speedbar-item-copy' `speedbar-item-rename' `speedbar-item-delete' | |
220 | ;; and `speedbar-item-info' | |
221 | ;; If the user kills the speedbar buffer in some way, the frame will | |
222 | ;; be removed. | |
223 | ;; 0.4.1 Bug fixes | |
224 | ;; <mark.jeffries@nomura.co.uk> added `speedbar-update-flag', | |
225 | ;; XEmacs fixes for menus, and tag sorting, and quit key. | |
226 | ;; Modeline now updates itself based on window-width. | |
227 | ;; Frame is cached when closed to make pulling it up again faster. | |
228 | ;; Speedbars window is now marked as dedicated. | |
229 | ;; Added bindings: <grossjoh@charly.informatik.uni-dortmund.de> | |
230 | ;; Long directories are now span multiple lines autmoatically | |
231 | ;; Added `speedbar-directory-button-trim-method' to specify how to | |
232 | ;; sorten the directory button to fit on the screen. | |
233 | ;; 0.4.2 Add one level of full-text cache. | |
234 | ;; Add `speedbar-get-focus' to switchto/raise the speedbar frame. | |
235 | ;; Editing thing-on-line will auto-raise the attached frame. | |
236 | ;; Bound `U' to `speedbar-up-directory' command. | |
237 | ;; Refresh will now maintain all subdirectories that were open | |
238 | ;; when the refresh was requested. (This does not include the | |
239 | ;; tags, only the directories) | |
240 | ;; 0.4.3 Bug fixes | |
241 | ;; 0.4.4 Added `speedbar-ignored-path-expressions' and friends. | |
242 | ;; Configuration menu items not displayed if dialog-mode not present | |
243 | ;; Speedbar buffer now starts with a space, and is not deleted | |
244 | ;; ewhen the speedbar frame is closed. This prevents the invisible | |
245 | ;; frame from preventing buffer switches with other buffers. | |
246 | ;; Fixed very bad bug in the -add-[extension|path] functions. | |
247 | ;; Added `speedbar-find-file-in-frame' which will always pop up a frame | |
248 | ;; that is already display a buffer selected in the speedbar buffer. | |
249 | ;; Added S-mouse2 as "power click" for always poping up a new frame. | |
250 | ;; and always rescanning with imenu (ditching the imenu cache), and | |
251 | ;; always rescanning directories. | |
252 | ;; 0.4.5 XEmacs bugfixes and enhancements. | |
253 | ;; Window Title simplified. | |
254 | ;; 0.4.6 Fixed problems w/ dedicated minibuffer frame. | |
255 | ;; Fixed errors reported by checkdoc. | |
256 | ;; 0.5 Mode-specific contents added. Controlled w/ the variable | |
257 | ;; `speedbar-mode-specific-contents-flag'. See speedbspec | |
258 | ;; for info on enabling this feature. | |
259 | ;; `speedbar-load-hook' name change and pointer check against | |
260 | ;; major-mode. Suggested by Sam Steingold <sds@ptc.com> | |
261 | ;; Quit auto-selects the attached frame. | |
262 | ;; Ranamed `speedbar-do-updates' to `speedbar-update-flag' | |
263 | ;; Passes checkdoc. | |
264 | ;; 0.5.1 Advice from ptype@dra.hmg.gb: | |
265 | ;; Use `post-command-idle-hook' in older emacsen | |
266 | ;; `speedbar-sort-tags' now works with imenu. | |
267 | ;; Unknown files (marked w/ ?) can now be operated on w/ | |
268 | ;; file commands. | |
269 | ;; `speedbar-vc-*-hook's for easilly adding new version control systems. | |
270 | ;; Checkin/out w/ vc will reset the scanners and update the * marker. | |
271 | ;; Fixed ange-ftp require compile time problem. | |
272 | ;; Fixed XEmacs menu bar bug. | |
273 | ;; Added `speedbar-activity-change-focus-flag' to control if the | |
274 | ;; focus changes w/ mouse events. | |
275 | ;; Added `speedbar-sort-tags' toggle to the menubar. | |
276 | ;; Added `speedbar-smart-directory-expand-flag' to toggle how | |
277 | ;; new directories might be inserted into the speedbar hierarchy. | |
278 | ;; Added `speedbar-visiting-[tag|file]hook' which is called whenever | |
279 | ;; speedbar pulls up a file or tag in the attached frame. Setting | |
280 | ;; this to `reposition-window' will do nice things to function tags. | |
281 | ;; Fixed text-cache default-directory bug. | |
282 | ;; Emacs 20 char= support. | |
283 | ;; 0.5.2 Customization | |
284 | ;; For older emacsen, you will need to download the new defcustom | |
285 | ;; package to get nice faces for speedbar | |
286 | ;; mouse1 Double-click is now the same as middle click. | |
287 | ;; No mouse pointer shape stuff for XEmacs (is there any?) | |
288 | ;; 0.5.3 Regressive support for non-custom enabled emacsen. | |
289 | ;; Fixed serious problem w/ 0.5.2 and ignored paths. | |
290 | ;; `condition-case' no longer used in timer fcn. | |
291 | ;; `speedbar-edit-line' is now smarter w/ special modes. | |
292 | ;; 0.5.4 Fixed more problems for Emacs 20 so speedbar loads correctly. | |
293 | ;; Updated some documentation strings. | |
294 | ;; Added customization menu item, and customized some more variables. | |
295 | ;; 0.5.5 Fixed so that there can be no ignored paths | |
296 | ;; Added .l & .lsp as lisp, suggested by: sshteingold@cctrading.com | |
297 | ;; You can now adjust height in `speedbar-frame-parameters' | |
298 | ;; XEmacs fix for use of `local-variable-p' | |
299 | ;; 0.5.6 Folded in XEmacs suggestions from Hrvoje Niksic <hniksic@srce.hr> | |
300 | ;; Several custom changes (group definitions, trim-method & others) | |
301 | ;; Keymap changes, and ways to add menu items. | |
302 | ;; Timer use changes for XEmacs 20.4 | |
303 | ;; Regular expression enhancements. | |
304 | ;; 0.6 Fixed up some frame definition stuff, use more convenience fns. | |
305 | ;; Rehashed frame creation code for better compatibility. | |
306 | ;; Fixed setting of kill-buffer hook. | |
307 | ;; Default speedbar has no menubar, mouse-3 is popup menu, | |
308 | ;; XEmacs double-click capability (Hrvoje Niksic <hniksic@srce.hr>) | |
309 | ;; General documentation fixup. | |
310 | ;; 0.6.1 Fixed button-3 menu for Emacs 20. | |
311 | ;; 0.6.2 Added autoload tag to `speedbar-get-focus' | |
