31 ;; Commentary:
|
|
|
32
|
|
|
33 ;; This is based on an early Emacs 19 info.el file.
|
|
|
34 ;;
|
|
|
35 ;; Note that Info-directory has been replaced by Info-directory-list,
|
|
|
36 ;; a search path of directories in which to find Info files.
|
|
|
37 ;; Also, Info tries adding ".info" to a file name if the name itself
|
|
|
38 ;; is not found.
|
|
|
39 ;;
|
|

|
|
|
52
|
|
|
53 ;; Modified 3/7/1991 by Dave Gillespie:
|
|
|
54 ;; (Author's address: daveg@synaptics.com or daveg@csvax.cs.caltech.edu)
|
|
|
55 ;;
|
|
|
56 ;; Added keys: i, t, <, >, [, ], {, }, 6, 7, 8, 9, 0.
|
|
|
57 ;; Look at help for info-mode (type ? in Info) for descriptions.
|
|
|
58 ;;
|
|
|
59 ;; If Info-directory-list is undefined and there is no INFOPATH
|
|
|
60 ;; in the environment, use value of Info-directory for compatibility
|
|
|
61 ;; with Emacs 18.57.
|
|
|
62 ;;
|
|
|
63 ;; All files named "localdir" found in the path are appended to "dir",
|
|
|
64 ;; the Info directory. For this to work, "dir" should contain only
|
|
|
65 ;; one node (Top), and each "localdir" should contain no ^_ or ^L
|
|
|
66 ;; characters. Generally they will contain only one or several
|
|
|
67 ;; additional lines for the top-level menu. Note that "dir" is
|
|
|
68 ;; modified in memory each time it is loaded, but not on disk.
|
|
|
69 ;;
|
|
|
70 ;; If "dir" contains a line of the form: "* Locals:"
|
|
|
71 ;; then the "localdir"s are inserted there instead of at the end.
|
|
|
72
|
|
|
73
|
|
|
74 ;; Modified 4/3/1991 by Dave Gillespie:
|
|
|
75 ;;
|
|
|
76 ;; Added Info-mode-hook (suggested by Sebastian Kremer).
|
|
|
77 ;; Also added epoch-info-startup/select-hooks from Simon Spero's info.el.
|
|
|
78 ;;
|
|
|
79 ;; Added automatic decoding of compressed Info files.
|
|
|
80 ;; See documentation for the variable Info-suffix-list. Default is to
|
|
|
81 ;; run "uncompress" on ".Z" files and "unyabba" on ".Y" files.
|
|
|
82 ;; (See comp.sources.unix v24i073-076 for yabba/unyabba, a free software
|
|
|
83 ;; alternative to compress/uncompress.)
|
|
|
84 ;; Note: "dir" and "localdir" files should not be compressed.
|
|
|
85 ;;
|
|
|
86 ;; Changed variables like Info-enable-edit to be settable by M-x set-variable.
|
|
|
87 ;;
|
|
|
88 ;; Added Info-auto-advance variable. If t, SPC and DEL will act like
|
|
|
89 ;; } and {, i.e., they advance to the next/previous node if at the end
|
|
|
90 ;; of the buffer.
|
|
|
91 ;;
|
|
|
92 ;; Changed `u' to restore point to most recent location in that node.
|
|
|
93 ;; Added `=' to do this manually at any time. (Suggested by David Fox).
|
|
|
94 ;;
|
|
|
95 ;; Changed `m' and `0-9' to try interpreting menu name as a file name
|
|
|
96 ;; if not found as a node name. This allows (dir) menus of the form,
|
|
|
97 ;; Emacs:: Cool text editor
|
|
|
98 ;; as a shorthand for
|
|
|
99 ;; Emacs:(emacs). Cool text editor
|
|
|
100 ;;
|
|
|
101 ;; Enhanced `i' to use line-number information in the index.
|
|
|
102 ;; Added `,' to move among all matches to a previous `i' command.
|
|
|
103 ;;
|
|
|
104 ;; Added `a' (Info-annotate) for adding personal notes to any Info node.
|
|
|
105 ;; Notes are not stored in the actual Info files, but in the user's own
|
|
|
106 ;; ~/.infonotes file.
|
|
|
107 ;;
|
|
|
108 ;; Added Info-footnote-tag, made default be "Ref" instead of "Note".
|
|
|
109 ;;
|
|
|
110 ;; Got mouse-click stuff to work under Emacs version 18. Check it out!
|
|
|
111 ;; Left and right clicks scroll the Info window.
|
|
|
112 ;; Middle click goes to clicked-on node, e.g., "Next:", a menu, or a note.
|
|
|
113
|
|
|
114
|
|
|
115 ;; Modified 6/29/1991 by Dave Gillespie:
|
|
|
116 ;;
|
|
|
117 ;; Renamed epoch-info-startup/select-hooks to Info-startup/select-hook.
|
|
|
118 ;;
|
|
|
119 ;; Made Info-select-node into a command on the `!' key.
|
|
|
120 ;;
|
|
|
121 ;; Added Info-mouse-support user option.
|
|
|
122 ;;
|
|
|
123 ;; Cleaned up the implementation of some routines.
|
|
|
124 ;;
|
|
|
125 ;; Added special treatment of quoted words in annotations: The `g'
|
|
|
126 ;; command for a nonexistent node name scans for an annotation
|
|
|
127 ;; (in any node of any file) containing that name in quotes: g foo RET
|
|
|
128 ;; looks for an annotation containing: "foo" or: <<foo>>
|
|
|
129 ;; If found, it goes to that file and node.
|
|
|
130 ;;
|
|
|
131 ;; Added a call to set up Info-directory-list in Info-find-node to
|
|
|
132 ;; work around a bug in GNUS where it calls Info-goto-node before info.
|
|
|
133 ;;
|
|
|
134 ;; Added completion for `g' command (inspired by Richard Kim's infox.el).
|
|
|
135 ;; Completion knows all node names for the current file, and all annotation
|
|
|
136 ;; tags (see above). It does not complete file names or node names in
|
|
|
137 ;; other files.
|
|
|
138 ;;
|
|
|
139 ;; Added `k' (Info-emacs-key) and `*' (Info-elisp-ref) commands. You may
|
|
|
140 ;; wish to bind these to global keys outside of Info mode.
|
|
|
141 ;;
|
|
|
142 ;; Allowed localdir files to be full dir-like files; only the menu part
|
|
|
143 ;; of each localdir is copied. Also, redundant menu items are omitted.
|
|
|
144 ;;
|
|
|
145 ;; Changed Info-history to hold only one entry at a time for each node,
|
|
|
146 ;; and to be circular so that multiple `l's come back again to the most
|
|
|
147 ;; recent node. Note that the format of Info-history entries has changed,
|
|
|
148 ;; which may interfere with external programs that try to operate on it.
|
|
|
149 ;; (Also inspired by Kim's infox.el).
|
|
|
150 ;;
|
|
|
151 ;; Changed `n', `]', `l', etc. to accept prefix arguments to move several
|
|
|
152 ;; steps at once. Most accept negative arguments to move oppositely.
|
|
|
153 ;;
|
|
|
154 ;; Changed `?' to bury *Help* buffer afterwards to keep it out of the way.
|
|
|
155 ;;
|
|
|
156 ;; Rearranged `?' key's display to be a little better for new users.
|
|
|
157 ;;
|
|
|
158 ;; Changed `a' to save whole window configuration and restore on C-c C-c.
|
|
|
159 ;;
|
|
|
160 ;; Fixed the bug reported by Bill Reynolds on gnu.emacs.bugs.
|
|
|
161 ;;
|
|
|
162 ;; Changed Info-last to restore window-start as well as cursor position.
|
|
|
163 ;;
|
|
|
164 ;; Changed middle mouse button in space after end of node to do Info-last
|
|
|
165 ;; if we got here by following a cross reference, else do Info-global-next.
|
|
|
166 ;;
|
|
|
167 ;; Added some new mouse bindings: shift-left = Info-global-next,
|
|
|
168 ;; shift-right = Info-global-prev, shift-middle = Info-last.
|
|
|
169 ;;
|
|
|
170 ;; Fixed Info-follow-reference not to make assumptions about length
|
|
|
171 ;; of Info-footnote-tag [Linus Tolke].
|
|
|
172 ;;
|
|
|
173 ;; Changed default for Info-auto-advance mode to be press-twice-for-next-node.
|
|
|
174 ;;
|
|
|
175 ;; Modified x-mouse-ignore to preserve last-command variable, so that
|
|
|
176 ;; press-twice Info-auto-advance mode works with the mouse.
|
|
|
177
|
|
|
178
|
|
|
179 ;; Modified 3/4/1992 by Dave Gillespie:
|
|
|
180 ;;
|
|
|
181 ;; Added an "autoload" command to help autoload.el.
|
|
|
182 ;;
|
|
|
183 ;; Changed `*' command to look for file `elisp' as well as for `lispref'.
|
|
|
184 ;;
|
|
|
185 ;; Fixed a bug involving footnote names containing regexp special characters.
|
|
|
186 ;;
|
|
|
187 ;; Fixed a bug in completion during `f' (or `r') command.
|
|
|
188 ;;
|
|
|
189 ;; Added TAB (Info-next-reference), M-TAB, and RET keys to Info mode.
|
|
|
190 ;;
|
|
|
191 ;; Added new bindings, `C-h C-k' for Info-emacs-key and `C-h C-f' for
|
|
|
192 ;; Info-elisp-ref. These bindings are made when info.el is loaded, and
|
|
|
193 ;; only if those key sequences were previously unbound. These bindings
|
|
|
194 ;; work at any time, not just when Info is already running.
|
|
|
195
|
|
|
196
|
|
|
197 ;; Modified 3/8/1992 by Dave Gillespie:
|
|
|
198 ;;
|
|
|
199 ;; Fixed some long lines that were causing trouble with mailers.
|
|
|
200
|
|
|
201
|
|
|
202 ;; Modified 3/9/1992 by Dave Gillespie:
|
|
|
203 ;;
|
|
|
204 ;; Added `C-h C-i' (Info-query).
|
|
|
205 ;;
|
|
|
206 ;; Added Info-novice mode, warns if the user attempts to switch to
|
|
|
207 ;; a different Info file.
|
|
|
208 ;;
|
|
|
209 ;; Fixed a bug that caused problems using compressed Info files
|
|
|
210 ;; and Info-directory-list at the same time.
|
|
|
211 ;;
|
|
|
212 ;; Disabled Info-mouse-support by default if Epoch or Hyperbole is in use.
|
|
|
213 ;;
|
|
|
214 ;; Added an expand-file-name call to Info-find-node to fix a small bug.
|
|
|
215
|
|
|
216
|
|
|
217 ;; Modified 5/22/1992 by Dave Gillespie:
|
|
|
218 ;;
|
|
|
219 ;; Added "standalone" operation: "emacs -f info" runs Emacs specifically
|
|
|
220 ;; for use as an Info browser. In this mode, the `q' key quits Emacs
|
|
|
221 ;; itself. Also, "emacs -f info arg" starts in Info file "arg" instead
|
|
|
222 ;; of "dir".
|
|
|
223 ;;
|
|
|
224 ;; Changed to prefer "foo.info" over "foo". If both exist, "foo" is
|
|
|
225 ;; probably a directory or executable program!
|
|
|
226 ;;
|
|
|
227 ;; Made control-mouse act like regular-mouse does in other buffers.
|
|
|
228 ;; (In most systems, this will be set-cursor for left-mouse, x-cut
|
|
|
229 ;; for right-mouse, and x-paste, which will be an error, for
|
|
|
230 ;; middle-mouse.)
|
|
|
231 ;;
|
|
|
232 ;; Improved prompting and searching for `,' key.
|
|
|
233 ;;
|
|
|
234 ;; Fixed a bug where some "* Menu:" lines disappeared when "dir"
|
|
|
235 ;; contained several nodes.
|
|
|
236
|
|
|
237
|
|
|
238 ;; Modified 9/10/1992 by Dave Gillespie:
|
|
|
239 ;;
|
|
|
240 ;; Mixed in support for XEmacs. Mouse works the same as in
|
|
|
241 ;; the other Emacs versions by default; added Info-lucid-mouse-style
|
|
|
242 ;; variable, which enables mouse operation similar to XEmacs's default.
|
|
|
243 ;;
|
|
|
244 ;; Fixed a bug where RET couldn't understand "* Foo::" if "Foo" was a
|
|
|
245 ;; file name instead of a node name.
|
|
|
246 ;;
|
|
|
247 ;; Added `x' (Info-bookmark), a simple interface to the annotation
|
|
|
248 ;; tags feature. Added `j' (Info-goto-bookmark), like `g' but only
|
|
|
249 ;; completes bookmarks.
|
|
|
250 ;;
|
|
|
251 ;; Added `<<tag>>' as alternate to `"tag"' in annotations.
|
|
|
252 ;;
|
|
|
253 ;; Added `v' (Info-visit-file), like Info-goto-node but specialized
|
|
|
254 ;; for going to a new Info file (with file name completion).
|
|
|
255 ;;
|
|
|
256 ;; Added recognition of gzip'd ".z" files.
|
|
|
257
|
|
|
258
|
|
|
259 ;; Modified 5/9/1993 by Dave Gillespie:
|
|
|
260 ;;
|
|
|
261 ;; Merged in various things from FSF's latest Emacs 19 info.el.
|
|
|
262 ;; Notably: Added Info-default-directory-list.
|
|
|
263
|
|
|
264
|
|
|
265 ;; Modified 6/2/1993 by Dave Gillespie:
|
|
|
266 ;;
|
|
|
267 ;; Changed to use new suffix ".gz" for gzip files.
|
|
|
268
|
|
|
269
|
|
|
270 ;; Modified 7/22/1993 by Dave Gillespie:
|
|
|
271 ;;
|
|
|
272 ;; Changed Info-footnote-tag to "See" instead of "Ref".
|
|
|
273 ;;
|
|
|
274 ;; Extended Info-fontify-node to work with FSF version of Emacs 19.
|
|
|
275
|
|
|
276 ;; Modified 7/30/1993 by Jamie Zawinski:
|
|
|
277 ;;
|
|
|
278 ;; Commented out the tty and fsf19 mouse support, because why bother.
|
|
|
279 ;; Commented out the politically incorrect version of XEmacs mouse support.
|
|
|
280 ;; Commented out mouse scrolling bindings because the party line on that
|
|
|
281 ;; is "scrollbars are coming soon."
|
|
|
282 ;; Commented out munging of help-for-help's doc; put it in help.el.
|
|
|
283 ;; Did Info-edit-map the modern XEmacs way.
|
|
|
284 ;; Pruned extra cruft from fontification and mouse handling code.
|
|
|
285 ;; Fixed ASCII-centric bogosity in unreading of events.
|
|
|
286
|
|
|
287 ;; Modified 8/11/95 by Chuck Thompson:
|
|
|
288 ;;
|
|
|
289 ;; Removed any pretense of ever referencing Info-directory since it
|
|
|
290 ;; wasn't working anyhow.
|
|
|
291
|
|
|
292 ;; Modified 4/5/97 by Tomasz J. Cholewo:
|
|
|
293 ;;
|
|
|
294 ;; Modified Info-search to use with-caps-disable-folding
|
|
|
295
|
|
|
296 ;; Modified 6/21/97 by Hrvoje Niksic
|
|
|
297 ;;
|
|
|
298 ;; Fixed up Info-next-reference to work sanely when n < 0.
|
|
|
299 ;; Added S-tab binding.
|

|
|
301 ;; Modified 1997-07-10 by Karl M. Hegbloom
|
|
|
302 ;;
|
|
|
303 ;; Added `Info-minibuffer-history'
|
