3 * Introduction
|
|
|
4 ==============
|
|
|

|

|
6 This file presents some general information about XEmacs. It is
|
|
276
|
7 primarily about the changes in recent XEmacs versions and its release
|
|
|
8 history.
|
|
223
|
9
|
|
|
10 Use `C-c C-f' to move to the next equal level of outline, and
|
|
|
11 `C-c C-b' to move to previous equal level. `C-h m' will give more
|
|
|
12 info about the Outline mode. Many commands are also available through
|
|
|
13 the menubar.
|
|
126
|
14
|
|
|
15 Users who would like to know which capabilities have been introduced
|
|
223
|
16 in each release should look at the appropriate section of this file.
|
|
|
17 Starting with version 20.0, XEmacs includes ChangeLogs, which can be
|
|
|
18 consulted for a more detailed list of changes.
|
|
|
19
|
|
|
20 Users interested in some of the details of how XEmacs differs from GNU
|
|
|
21 Emacs should read the section "What's Different?" near the end of this
|
|
|
22 file.
|
|
|
23
|
|
225
|
24 N.B. The term "GNU Emacs" refers to any release of Emacs Version
|
|
|
25 19 from the Free Software Foundation's GNU Project. (We do not
|
|
|
26 say just "Emacs" as Richard M. Stallman ["RMS"] prefers, because
|
|
|
27 it is clearly a more generic term.) The term "XEmacs" refers to
|
|
223
|
28 this program or to its predecessors "Era" and "Lucid Emacs". The
|
|
|
29 predecessor of all these program is called "Emacs 18". When no
|
|
|
30 particular version is implied, "Emacs" will be used.

33 * Changes in XEmacs 21.2
|
|
|
34 ========================
|
|
|
35 None yet.
|
|
|
36
|
|
274
|
37 * Changes in XEmacs 21.0
|
|
209
|
38 ========================
|
|
|
39
|
|
219
|
40 ** XEmacs has been unbundled into constituent installable packages.
|
|
298
|
41 See the Info documentation under "Packages" for more information.
|
|
|
42 See the file `etc/PACKAGES' in the distribution for a partial list of
|
|
|
43 packages available at the time of the 21.0 release.
|
|
219
|
44
|
|
290
|
45 ** XEmacs is now supported under Microsoft Windows 95/98 and Windows
|
|
|
46 NT operating systems. For starters, look at the XEmacs on Windows FAQ
|
|
294
|
47 at <URL:http://jagor.srce.hr/~hniksic/xemacs-on-windows-faq.txt>. To
|
|
290
|
48 discuss Windows-specific issues, subscribe to the mailing list at
|
|
|
49 <xemacs-nt-request@xemacs.org>.
|
|
|
50
|
|
|
51 ** XEmacs will now use `XEmacs' as its application class if it finds
|
|
|
52 any `XEmacs' resources in the resource database. Otherwise, it will
|
|
|
53 continue to use the `Emacs' class.
|
|
|
54
|
|
294
|
55 ** The options menu has been ported to Custom.
|
|
|
56 This means that each entry in the options menu acts as if you had customized
|
|
|
57 the corresponding variable by hand. ### WARNING: there is currently no
|
|
|
58 upgrading function to help you port your old options settings to the new
|
|
|
59 format. Consequently, if you want to modify the options for XEmacs 21, you
|
|
|
60 will have to set them all again through the menu, and remove the code loading
|
|
|
61 .xemacs-options from your .emacs.
|
|
|
62
|
|
278
|
63 ** When the Zmacs region is active, `M-x query-replace' and the other
|
|
|
64 replace commands now operate on the region contents only.
|
|
|
65
|
|
371
|
66 ** Using the new `-private' option, you can make XEmacs use a private
|
|
|
67 colormap.
|
|
223
|
68
|
|
284
|
69 ** The `imenu' package has been ported to XEmacs and is available as a
|
|
|
70 package.
|
|
|
71
|
|
219
|
72 ** `echo-keystrokes' can now be a floating-point number, so that you
|
|
276
|
73 can set it to intervals shorter than one second.
|
|
219
|
74
|
|
|
75 (setq echo-keystrokes 0.1)
|
|
|
76
|
|
280
|
77 ** The new command `center-to-window-line' works like `recenter'
|
|
|
78 (bound to `C-l'), only it does not redisplay the whole display area.
|
|
|
79
|
|
284
|
80 ** The M-. command will now first search through exact tags matches,
|
|
219
|
81 and then through inexact matches, as one would expect.
|
|
|
82
|
|
223
|
83 ** The new variable `user-full-name' can be used to customize one's
|
|
|
84 name when using the Emacs mail and news reading facilities.
|
|
|
85
|
|
|
86 Normally, `user-full-name' is a function that returns the full name of
|
|
|
87 a user or UID, as specified by the system -- for instance,
|
|
|
88 (user-full-name "root") returns something like "Super-User". However,
|
|
|
89 when the function is called without arguments, it will return the
|
|
|
90 value of the `user-full-name' variable. The `user-full-name' variable
|
|
|
91 is initialized using the environment variable NAME and (failing that)
|
|
|
92 the user's system name.
|
|
|
93
|
|
371
|
94 The behaviour of the `user-full-name' function with an argument
|
|
225
|
95 specified is unchanged.
|
|
223
|
96
|
|
|
97 ** The new command `M-x customize-changed-options' lets you customize
|
|
|
98 all the options whose default values have changed in recent Emacs
|
|
|
99 versions. You specify a previous Emacs version number as argument,
|
|
|
100 and the command creates a customization buffer showing all the
|
|
|
101 customizable options whose default values were changed since that
|
|
|
102 version.
|
|
|
103
|
|
|
104 If you don't specify a particular version number argument, then the
|
|
|
105 customization buffer shows all the customizable options for which
|
|
|
106 Emacs versions of changes are recorded.
|
|
|
107
|
|
249
|
108 ** The new command `add-log-convert' can be used to convert the
|
|
|
109 old-style (pre-20.3) ChangeLog buffers to new style, for
|
|
|
110 consistency. A reminder: if you wish to revert to old-style
|
|
|
111 ChangeLogs instead, customize the value of `add-log-time-format'
|
|
|
112 variable.
|
|
|
113
|
|
284
|
114 ** The new command `zap-up-to-char' is now available. It is similar
|
|
|
115 to `zap-to-char', except that it does not delete the searched-for
|
|
|
116 character. It is not bound to a key by default.
|
|
|
117
|
|
|
118 ** You can now store a number into a register with `C-u NUMBER C-x r n'
|
|
|
119 REG, increment it by INC with `C-u INC C-x r + REG' (to increment by
|
|
|
120 one, omit C-u INC), and insert it in the buffer with `C-x r g REG'.
|
|
|
121 This is useful for writing keyboard macros.
|
|
|
122
|
|
|
123 ** The M-: command, when given a prefix argument, will now insert its
|
|
|
124 result to the current buffer.
|
|
|
125
|
|
|
126 ** The `C-h c' command, when given a prefix argument, will now insert
|
|
|
127 the message into the current buffer.
|
|
|
128
|
|
298
|
129 ** Horizontally split windows may now be dragged using the mouse.
|
|
|
130 Because of this, the dividers between vertical windows are always
|
|
|
131 visible. To turn it off, set `vertical-divider-always-visible-p' to
|
|
|
132 nil.
|
|
286
|
133
|
|
223
|
134 ** XEmacs/Mule (internationalization) changes.
|
|
|
135
|
|
284
|
136 *** Mule support now works on TTY's. Use `set-terminal-coding-system'
|
|
|
137 and `set-keyboard-coding-system' to specify the coding system of your
|
|
|
138 display and keyboard.
|
|
274
|
139
|
|
225
|
140 *** Egg/SJ3 input method is now officially supported. Quail and
|
|
|
141 Egg/Skk have been available through the generalized Leim since 20.3.
|
|
223
|
142
|
|
|
143 *** Localized Japanese menubars are available if XEmacs is built with
|
|
|
144 XFONTSET and either the X11 libraries are built with X_LOCALE defined
|
|
|
145 or the native C libraries support Japanese localization. This has
|
|
|
146 been available since 20.3, only it hasn't been announced before.
|
|
219
|
147
|
|
290
|
148 ** Jamie Zawinski's `gdb-highlight' extension is now distributed with
|
|
284
|
149 the `debug' package. gdb-highlight makes most objects printed in a
|
|
|
150 gdb buffer be mouse-sensitive: as text shows up in the buffer, it is
|
|
|
151 parsed, and objects which are recognized have context-sensitive
|
|
|
152 commands attached to them. To use it, add the following to `.emacs':
|
|
|
153
|
|
286
|
154 (add-hook 'gdb-mode-hook (lambda () (require 'gdb-highlight)))
|
|
284
|
155
|
|
290
|
156 ** The package popper.el is now included in the edit-utils package.
|
|
|
157 It has been greatly enhanced with respect to the one once included
|
|
|
158 with the ilisp package and should work well under XEmacs 21.0.
|
|
|
159
|
|
278
|
160 ** C mode changes
|
|
|
161
|
|
|
162 *** Multiline macros are now handled, both as they affect indentation,
|
|
|
163 and as recognized syntax. New syntactic symbol cpp-macro-cont is
|
|
|
164 assigned to second and subsequent lines of a multiline macro
|
|
|
165 definition.
|
|
|
166
|
|
|
167 *** A new style "user" which captures all non-hook-ified
|
|
|
168 (i.e. top-level) .emacs file variable setings and customizations.
|
|
|
169 Style "cc-mode" is an alias for "user" and is deprecated. "gnu" style
|
|
|
170 is still the default however.
|
|
|
171
|
|
|
172 *** "java" style now conforms to Sun's JDK coding style.
|
|
|
173
|
|
|
174 *** There are new commands c-beginning-of-defun, c-end-of-defun which
|
|
|
175 are alternatives which you could bind to C-M-a and C-M-e if you prefer
|
|
|
176 them. They do not have key bindings by default.
|
|
|
177
|
|
|
178 *** New and improved implementations of M-a (c-beginning-of-statement)
|
|
|
179 and M-e (c-end-of-statement).
|
|
|
180
|
|
|
181 *** C++ namespace blocks are supported, with new syntactic symbols
|
|
|
182 namespace-open, namespace-close, and innamespace.
|
|
|
183
|
|
|
184 *** File local variable settings of c-file-style and c-file-offsets
|
|
|
185 makes the style variables local to that buffer only.
|
|
|
186
|
|
|
187 *** New indentation functions c-lineup-close-paren,
|
|
|
188 c-indent-one-line-block, c-lineup-dont-change.
|
|
|
189
|
|
|
190 *** Improvements (hopefully!) to the way CC Mode is loaded. You
|
|
|
191 should now be able to do a (require 'cc-mode) to get the entire
|
|
|
192 package loaded properly for customization in your .emacs file. A new
|
|
|
193 variable c-initialize-on-load controls this and is t by default.
|
|
|
194
|
|
251
|
195 ** In Text mode, now only blank lines separate paragraphs.
|
|
|
196 This makes it possible to get the full benefit of Adaptive Fill mode
|
|
|
197 in Text mode, and other modes derived from it (such as Mail mode).
|
|
278
|
198 TAB in Text mode now runs the command indent-relative; this makes a
|
|
|
199 practical difference only when you use indented paragraphs.
|
|
251
|
200
|
|
|
201 As a result, the old Indented Text mode is now identical to Text mode,
|
|
|
202 and is an alias for it.
|
|
|
203
|
|
|
204 If you want spaces at the beginning of a line to start a paragraph,
|
|
|
205 use the new mode, Paragraph Indent Text mode.
|
|
|
206
|
|
298
|
207 ** Changes to Gnus, the XEmacs newsreader.
|
|
|
208
|
|
|
209 *** New functionality for using Gnus as an offline newsreader has been
|
|
|
210 added. A plethora of new commands and modes have been added. See the
|
|
|
211 Gnus manual for the full story.
|
|
|
212
|
|
|
213 *** The nndraft backend has returned, but works differently than
|
|
|
214 before. All Message buffers are now also articles in the nndraft
|
|
|
215 group, which is created automatically.
|
|
|
216
|
|
|
217 *** `gnus-alter-header-function' can now be used to alter header
|
|
|
218 values.
|
|
|
219
|
|
|
220 *** `gnus-summary-goto-article' now accept Message-ID's.
|
|
|
221
|
|
|
222 *** A new Message command for deleting text in the body of a message
|
|
|
223 outside the region: `C-c C-v'.
|
|
|
224
|
|
|
225 *** You can now post to component group in nnvirtual groups with
|
|
|
226 `C-u C-c C-c'.
|
|
|
227
|
|
|
228 *** `nntp-rlogin-program' -- new variable to ease customization.
|
|
|
229
|
|
|
230 *** `C-u C-c C-c' in `gnus-article-edit-mode' will now inhibit
|
|
|
231 re-highlighting of the article buffer.
|
|
|
232
|
|
|
233 *** New element in `gnus-boring-article-headers' -- `long-to'.
|
|
|
234
|
|
|
235 *** `M-i' symbolic prefix command. See the section "Symbolic
|
|
|
236 Prefixes" in the Gnus manual for details.
|
|
|
237
|
|
|
238 *** `L' and `I' in the summary buffer now take the symbolic prefix
|
|
|
239 `a' to add the score rule to the "all.SCORE" file.
|
|
|
240
|
|
|
241 *** `gnus-simplify-subject-functions' variable to allow greater
|
|
|
242 control over simplification.
|
|
|
243
|
|
|
244 *** `A T' -- new command for fetching the current thread.
|
|
|
245
|
|
|
246 *** `/ T' -- new command for including the current thread in the
|
|
|
247 limit.
|
|
|
248
|
|
|
249 *** `M-RET' is a new Message command for breaking cited text.
|
|
|
250
|
|
|
251 *** \\1-expressions are now valid in `nnmail-split-methods'.
|
|
|
252
|
|
|
253 *** The `custom-face-lookup' function has been removed.
|
|
|
254 If you used this function in your initialization files, you must
|
|
|
255 rewrite them to use `face-spec-set' instead.
|
|
|
256
|
|
|
257 *** Cancelling now uses the current select method. Symbolic prefix
|
|
|
258 `a' forces normal posting method.
|
|
|
259
|
|
|
260 *** New command to translate M******** sm*rtq**t*s into proper text
|
|
|
261 -- `W d'.
|
|
|
262
|
|
|
263 *** For easier debugging of nntp, you can set `nntp-record-commands'
|
|
|
264 to a non-nil value.
|
|
|
265
|
|
|
266 *** nntp now uses ~/.authinfo, a .netrc-like file, for controlling
|
|
|
267 where and how to send AUTHINFO to NNTP servers.
|
|
|
268
|
|
|
269 *** A command for editing group parameters from the summary buffer
|
|
|
270 has been added.
|
|
|
271
|
|
|
272 *** A history of where mails have been split is available.
|
|
|
273
|
|
|
274 *** A new article date command has been added -- `article-date-iso8601'.
|
|
|
275
|
|
|
276 *** Subjects can be simplified when threading by setting
|
|
|
277 `gnus-score-thread-simplify'.
|
|
|
278
|
|
|
279 *** A new function for citing in Message has been added --
|
|
|
280 `message-cite-original-without-signature'.
|
|
|
281
|
|
|
282 *** `article-strip-all-blank-lines' -- new article command.
|
|
|
283
|
|
|
284 *** A new Message command to kill to the end of the article has
|
|
|
285 been added.
|
|
|
286
|
|
|
287 *** A minimum adaptive score can be specified by using the
|
|
|
288 `gnus-adaptive-word-minimum' variable.
|
|
|
289
|
|
|
290 *** The "lapsed date" article header can be kept continually
|
|
|
291 updated by the `gnus-start-date-timer' command.
|
|
|
292
|
|
|
293 *** Web listserv archives can be read with the nnlistserv backend.
|
|
|
294
|
|
|
295 *** Old dejanews archives can now be read by nnweb.
|
|
|
296
|
|
|
297 *** Byte-compilation of user-specs now works under XEmacs.
|
|
|
298
|
|
290
|
299 ** The `dir' files are no longer essential for functioning of the Info
|
|
|
300 subsystem. If the `dir' file does not exist in an Info directory, the
|
|
|
301 relevant information will be generated on-the-fly.
|
|
278
|
302
|
|
371
|
303 This behaviour can be customized, look for `Info-auto-generate-directory'
|
|
292
|
304 and `Info-save-auto-generated-dir' in the `info' customization group.

307 * Lisp and internal changes in XEmacs 21.0
|
|
219
|
308 ==========================================
|
|
|
309
|
|
274
|
310 ** It is now possible to build XEmacs with support for 31-bit Lisp
|
|
|
311 integers (normally, Lisp integers are only 28 bits wide on 32-bit
|
|
|
312 machines.) Configure with --use-minimal-tagbits to test. With this
|
|
284
|
313 change, the maximum buffer size on 32-bit machines is increased from
|
|
|
314 128M to 1G. This setting will be made default in a future XEmacs
|
|
|
315 version.
|
|
|
316
|
|
286
|
317 ** Specifier changes.
|
|
|
318
|
|
|
319 *** When instantiating a specifier, the window locale now has a higher
|
|
|
320 precedence than the buffer locale. This is because the window locale
|
|
|
321 is more specific than the buffer locale.
|
|
|
322
|
|
290
|
323 *** The new macro `let-specifier' can be used to temporarily add
|
|
|
324 specifications to specifiers. See the documentation for details.
|
|
|
325
|
|
286
|
326 *** The new specifiers `vertical-scrollbar-visible-p' and
|
|
|
327 `horizontal-scrollbar-visible-p' may be used to control scrollbar
|
|
290
|
328 visibility. Previously, the only way to remove a scrollbar was to set
|
|
|
329 its size to 0. This method is still supported for backward
|
|
|
330 compatibility.
|
|
286
|
331
|
|
|
332 *** The new specifiers `scrollbar-on-left-p' and `scrollbar-on-top-p'
|
|
|
333 may be used to control the position of the vertical and horizontal
|
|
|
334 toolbar. Previously, their position could be changed only through the
|
|
|
335 use of X resources.
|
|
|
336
|
|
|
337 *** The new draggable vertical dividers between windows may be turned
|
|
298
|
338 off using the `vertical-divider-always-visible-p' specifier. When
|
|
|
339 this is set to nil, the vertical dividers between windows are shown
|
|
|
340 only when needed, and they are not draggable.
|
|
286
|
341
|
|
|
342 Other properties of the vertical dividers may be controlled using
|
|
|
343 `vertical-divider-shadow-thickness', `vertical-divider-line-width' and
|
|
|
344 `vertical-divider-spacing' specifiers, which see.
|
|
|
345
|
|
284
|
346 ** Frame focus management changes.
|
|
|
347
|
|
|
348 *** When the variable focus-follows-mouse is non-nil, `select-frame'
|
|
|
349 no longer permanently selects a different frame. The frame selection
|
|
|
350 is temporary and is reverted when the current command terminates, much
|
|
|
351 like the buffer selected by `set-buffer'. This is the same as in FSF
|
|
|
352 Emacs.
|
|
|
353
|
|
|
354 *** The new function `focus-frame' sets the window system focus to
|
|
|
355 FRAME (and selects it), regardless of the value of
|
|
|
356 `focus-follows-mouse'. Doing this is not well behaved, so be
|
|
|
357 absolutely sure that you want this.
|
|
|
358
|
|
|
359 The code that uses `select-frame' only to get the window manager focus
|
|
|
360 should be changed to use `set-frame-focus' instead, so that they keep
|
|
|
361 working when `focus-follows-mouse' is non-nil.
|
|
|
362
|
|
|
363 *** The special forms `save-selected-frame' and `with-selected-frame'
|
|
|
364 can now be used to temporarily change selected frame.
|
|
|
365
|
|
|
366 *** The behavior of `other-frame' command (`C-x 5 o') is unaffected by
|
|
|
367 these changes.
|
|
280
|
368
|
|
290
|
369 ** The function `select-window' now has an optional second argument
|
|
|
370 NORECORD which if non-nil inhibits the recording of a buffer change.
|
|
|
371
|
|
|
372 ** The function `vertical-motion' now correctly handles the second,
|
|
|
373 optional WINDOW argument. A new third argument PIXELS, if non-nil,
|
|
|
374 indicates that the returned motion should be in pixels.
|
|
|
375
|
|
|
376 ** The new function `vertical-motion-pixels' is similar to
|
|
|
377 vertical-motion but takes as input a vertical motion in pixels.
|
|
|
378
|
|
|
379 ** The new functions window-text-area-pixel-{width,height,edges} can
|
|
|
380 be used to obtain information about the text-displaying area of a
|
|
|
381 window.
|
|
|
382
|
|
|
383 ** The new functions `shrink-window-pixels' and `enlarge-window-pixels'
|
|
|
384 can be used to adjust the size of a window by a pixel amount.
|
|
|
385
|
|
|
386 ** The new function `window-displayed-text-pixel-height' can be used
|
|
|
387 to determine the height of the text actually displayed in a window.
|
|
|
388
|
|
284
|
389 ** The arithmetic comparison functions <, >, =, /= now accept a
|
|
|
390 variable number of arguments.
|
|
280
|
391
|
|
|
392 This means that if you want to test whether A < B < C, you can write
|
|
|
393 it as (< A B C) instead of (and (< A B) (< B C)). Likewise,
|
|
371
|
394 (apply #'> LIST) now tests if LIST is monotonously increasing -- and
|
|
280
|
395 so on.
|
|
|
396
|
|
223
|
397 ** The XEmacs hashtables now have a consistent read/print syntax.
|
|
|
398 This means that a hashtable will be readably printed in a
|
|
|
399 structure-like form:
|
|
|
400
|
|
|
401 #s(hashtable size 2 data (key1 value1 key2 value2))
|
|
|
402
|
|
|
403 When XEmacs reads this form, it will create a new hashtable according
|
|
|
404 to description. This allows you to easily dump hashtables to files
|
|
|
405 using `prin1', and read them back in using `read'.
|
|
|
406
|
|
|
407 If `print-readably' is non-nil, a more relaxed syntax is used; for
|
|
|
408 instance:
|
|
|
409
|
|
|
410 #<hashtable size 2/13 data (key1 value1 key2 value2) 0x874d>
|
|
|
411
|
|
286
|
412 ** It is now possible to build XEmacs with LDAP support.
|
|
|
413 You will need to install a LDAP library first. The following have
|
|
|
414 been tested:
|
|
|
415 - LDAP 3.3 from the University of Michigan
|
|
|
416 (get it from <URL:http://www.umich.edu/~dirsvcs/ldap/>)
|
|
|
417 - LDAP SDK 1.0 from Netscape Corp.
|
|
|
418 (get it from <URL:http://developer.netscape.com/>)
|
|
284
|
419
|
|
241
|
420 ** When profiling is in effect, a call-count of all recorded functions
|
|
|
421 is now calculated. This information is stored in
|
|
|
422 `call-count-profile-table', and is utilized by `profile-results' as
|
|
286
|
423 well as the new command `profile-call-count-results'.
|
|
241
|
424
|
|
284
|
425 ** It is now an error to change the value of a symbol whose name
|
|
|
426 starts with a colon, if it is interned in the standard obarray.
|
|
|
427
|
|
|
428 However, setting such a symbol to its proper value, which is that
|
|
|
429 symbol itself, is not an error. This is for the sake of programs that
|
|
|
430 support pre-19.12 XEmacs and pre-20 GNU Emacs by explicitly setting
|
|
|
431 these variables to themselves.
|
|
|
432
|
|
|
433 ** The `concat' function no longer accepts integer arguments.
|
|
|
434
|
|
278
|
435 ** The new function `string' concatenates all its argument characters
|
|
|
436 and returns the resulting string. This is consistent with other
|
|
|
437 functions, like `list', `vector', etc.
|
|
|
438
|
|
290
|
439 ** The function `temp-directory' is now available to return the
|
|
|
440 directory to store temporary files. On Unix this will be obtained
|
|
|
441 from TMPDIR, defaulting to `/tmp'.
|
|
|
442
|
|
284
|
443 ** The function load-average now accepts an optional argument
|
|
|
444 USE-FLOATS. If it is non-nil, the load average values are returned as
|
|
|
445 floating point numbers, rather than as integers to be divided by 100.
|
|
278
|
446
|
|
223
|
447 ** The `make-event' function now supports the TYPE and PLIST
|
|
276
|
448 arguments, which can be used to create various events from Lisp. See
|
|
|
449 the documentation for details.
|
|
223
|
450
|
|
219
|
451 ** `function-interactive' is a new function that returns the
|
|
|
452 interactive specification of a funcallable object.
|
|
|
453
|
|
|
454 ** The new `lmessage' function allows printing of a formatted message
|
|
|
455 with a particular label.
|
|
|
456
|
|
223
|
457 (lmessage 'progress "Processing... %d" counter)
|
|
219
|
458
|
|
|
459 This function is more convenient than `display-message' because it
|
|
|
460 automatically applies `format' to its arguments.
|
|
|
461
|
|
|
462 ** The new `lwarn' function, analogous to `lmessage', allows printing
|
|
|
463 a formatted warning, with a non-default CLASS or LABEL.
|
|
|
464
|
|
284
|
465 ** The new function `split-path' can now be used to explode the
|
|
|
466 components of a colon-separated search path into a list.
|
|
|
467
|
|
|
468 (split-path "foo:bar")
|
|
|
469 => ("foo" "bar")
|
|
|
470
|
|
274
|
471 ** Specifiers and symbols whose value is a specifier are now allowed
|
|
276
|
472 as modeline specifications.
|
|
274
|
473
|
|
|
474 ** defcustom now accepts the keyword `:version'. Use this to specify
|
|
|
475 in which version of Emacs a certain variable's default value changed.
|
|
|
476 For example,
|
|
|
477
|
|
|
478 (defcustom foo-max 34 "*Maximum number of foo's allowed."
|
|
|
479 :type 'integer
|
|
|
480 :group 'foo
|
|
276
|
481 :version "21.0")
|
|
274
|
482
|
|
|
483 This information is used to control the customize-changed-options
|
|
|
484 command.
|
|
|
485
|
|
225
|
486 ** The line number tracking in modeline is now efficient, even for
|
|
|
487 very large buffers. This is achieved by caching the line numbers of
|
|
|
488 recent buffer positions, and reusing them. This cache is used only in
|
|
|
489 the buffers where `line-number-mode' is in effect.
|
|
259
|
490
|
|
274
|
491 ** When the new GNU Malloc aka Doug Lea Malloc is available, it will
|
|
|
492 be used. This should result in better performance on Linux systems
|
|
|
493 with libc6.
|
|
|
494
|
|
276
|
495 ** The code XEmacs uses to assemble its various paths into the
|
|
|
496 directory hierarchy has been rewritten to support the package system.
|
|
298
|
497 Look under "Startup Paths" in the Info documentation for more
|
|
|
498 information.
|
|
276
|
499
|
|
371
|
500 *** site-lisp is now longer part of the load-path by default.
|
|
276
|
501 Its use is deprecated, but you can specify --with-site-lisp=yes at the
|
|
|
502 configure command line to get it back.
|
|
|
503
|
|
|
504 *** `Info-default-directory-list' is now obsolete. If you want to
|
|
|
505 change the path which XEmacs uses to search for info files, set
|
|
|
506 `Info-directory-list' instead.
