129 This is the introduction to a list of frequently asked questions (FAQ's)
|
|
|
130 about XEmacs with answers. This article contains a listing of the
|
|
|
131 questions; subsequent articles contain the questions and answers.
|
|
|
132
|
|
|
133 This is not a substitute for general Emacs questions, and actually
|
|
|
134 includes nothing that might help a novice learn to use Emacs or XEmacs.
|
|
|
135 For that, check out the regular Emacs lists, the tutorial inside of
|
|
|
136 XEmacs (look on the Help menu), or the O'Reilly book @cite{Learning GNU
|
|
|
137 Emacs}. This FAQ focuses on specific issues regarding XEmacs. If you
|
|
|
138 don't find the answer here, perhaps it really is a more general
|
|
|
139 question, and check the GNU Emacs FAQ for more information, as well.
|
|
|
140
|
|
|
141 The FAQ list is posted to reduce the noise level in the
|
|
|
142 @samp{comp.emacs.xemacs} newsgroup which results from the repetition of
|
|
|
143 frequently asked questions, wrong answers to these questions,
|
|
|
144 corrections to the wrong answers, corrections to the corrections,
|
|
|
145 debate, name calling, etc. Also, it serves as a repository of the
|
|
|
146 canonical ``best'' answers to these questions. However, if you know a
|
|
|
147 better answer or even a slight change that improves an answer, please
|
|
|
148 tell me!
|
|
|
149
|
|
|
150 If you know the answer of a question is in the FAQ list, please reply to
|
|
|
151 the question by e-mail instead of posting. Help reduce noise!
|
|
|
152
|
|
|
153 Please suggest new questions, answers, wording changes, deletions, etc.
|
|
|
154 The most helpful form for suggestions is a context diff (i.e. the output
|
|
|
155 of @samp{diff -c}). Include @samp{FAQ} in the subject of messages sent
|
|
|
156 to us about the FAQ list.
|
|
|
157
|
|
|
158 Please do not send questions to us just because you do not want to
|
|
|
159 disturb a lot of people and you think we would know the answer. We do
|
|
|
160 not have time to answer questions individually and keep up with
|
|
|
161 everything else we have to get done.

|
|
163 Many thanks need to go to all contributors on the old alt.lucid-emacs.*
|
|
|
164 and current comp.emacs.xemacs groups. This would never have been
|
|
|
165 collected without you.

|
174 An alternative to GNU Emacs, originally based on an early alpha version
|
|
70
|
175 of FSF's version 19. XEmacs was known as Lucid Emacs through version
|
|
|
176 19.10. Almost all features of GNU Emacs are supported in XEmacs (the
|
|
|
177 ones that aren't supported are generally implemented in a better way in
|
|
|
178 XEmacs). The maintainers of XEmacs actively track changes to GNU Emacs
|
|
|
179 while also working to add new features never before seen in Emacs.

293 @dfn{M-x} means that the @key{Meta} key and the @key{X} key should be

295 the @key{Meta} key is labelled @samp{Alt} or with a diamond. Some

296 keyboards don't have a @key{Meta} key at all; then you can get the

297 equivalent by typing the @key{Esc} key followed by the @key{X} key.

|
|
|
358 InfoDock is an integrated productivity toolset, mainly aimed at
|
|
70
|
359 technical people. It is built atop the XEmacs variant of GNU Emacs and
|
|
|
360 so has all of the power of Emacs, but with an easier to use and more
|
|
|
361 comprehensive menu-based user interface. The next section describes how
|
|
|
362 it differs from XEmacs and GNU Emacs from the Free Software Foundation.
|
|
|
363
|
|
|
364 The quickest way to get a feel for InfoDock is to browse the InfoDock
|
|
|
365 Manual, especially the section on tools. This will help you decide
|
|
|
366 whether or not to download InfoDock for local use. This manual is
|
|
|
367 available in gzipped Postscript form, alongside the InfoDock
|
|
|
368 distribution. (See below for FTP retrieval instructions.)
|
|

|
369
|
|
|
370 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
371 environment. Although InfoDock is customizable, it is not intended for
|
|
|
372 people who like basic versions of Emacs which need to be customized
|
|
|
373 extensively for local use; standard Emacs distributions are better for
|
|
|
374 such uses. InfoDock is for those people who want a complete,
|
|
|
375 pre-customized environment in one package, which they need not touch
|
|
|
376 more than once or twice a year to update to new revisions.
|
|
|
377
|
|
70
|
378 InfoDock is pre-built for SPARCstations running SunOS V4 or V5
|
|
|
379 (Solaris). It is intended for use on a color display, although most
|
|
|
380 features will work on monochrome monitors. Simply unpack InfoDock
|
|
|
381 according to the instructions in the ID-INSTALL file and you are ready
|
|
|
382 to run.

384 The InfoDock Manual is concise, yet sufficient as a user guide for users
|
|
|
385 who have never used an Emacs-type editor before. For users who are
|
|
|
386 already familiar with Emacs, it supplements the information in the GNU
|
|
|
387 Emacs Manual.
|
|
|
388
|
|
|
389 InfoDock menus are much more extensive and more mature than standard
|
|
|
390 Emacs menus. Each menu offers a @samp{Manual} item which displays
|
|
|
391 documentation associated with the menu's functions.

419 InfoDock saves a more extensive set of user options than other Emacs
|
|
|
420 versions.
|
|
|
421
|
|
|
422 InfoDock inserts a useful file header in many file types, showing the
|
|
|
423 author, summary, and last modification time of each file. A summary
|
|
|
424 program can then be used to summarize all of the files in a directory,
|
|
|
425 for easy MANIFEST file creation.
|
|
|
426
|
|
|
427 Your working set of buffers is automatically saved and restored (if you
|
|
|
428 answer yes to a prompt) between InfoDock sessions.
|
|
|
429
|
|
|
430 Refined color choices for code highlighting are provided for both dark and
|
|
|
431 light background display frames.
|
|
|
432
|
|
|
433 The @kbd{C-z} key prefix performs frame-based commands which parallel the
|
|
|
434 @kbd{C-x} key prefix for window-based commands.
|
|
|
435
|
|
|
436 The Smart Menu system is included for producing command menus on dumb
|
|
70
|
437 terminals. (InfoDock does not yet run on dumb terminals but will in 1995.)
|

438
|
|

439 Lisp libraries are better categorized according to function.
|

441 Extensions and improvements to many areas of Emacs are included, such as:
|
|
|
442 paragraph filling, mail reading with Rmail, shell handling, outlining, code
|
|
|
443 highlighting and browsing, and man page browsing.
|
|

444
|
|
|
445 InfoDock questions, answers and discussion should go to the mail list

|
|
|
525
|
|
|
526 You should only need to add some stuff to the configure command line. To tell
|
|
|
527 it to compile in netaudio support:
|
|
|
528
|
|
|
529 @example
|
|
|
530 --with-sound=both
|
|
|
531 @end example
|
|
|
532
|
|
|
533 (Or @samp{--with-sound=nas} if you don't want native sound support for
|
|
|
534 some reason.) To tell it where to find the netaudio includes and
|
|
|
535 libraries:
|
|
|
536
|
|
|
537 @example
|
|
|
538 --site-libraries=WHATEVER
|
|
|
539 --site-includes=WHATEVER
|
|
|
540 @end example
|
|
|
541
|
|
|
542 Then (fingers crossed) it should compile and it will use netaudio if you
|
|
|
543 have a server running corresponding to the X server. The netaudio server
|
|
|
544 has to be there when XEmacs starts. If the netaudio server goes away and
|
|
|
545 another is run, XEmacs should cope (fingers crossed, error handling in
|
|
|
546 netaudio isn't perfect).
|
|
|
547
|
|
|
548 BTW, netaudio has been renamed as it has a name clash with something
|
|
|
549 else, so if you see references to NAS or Network Audio System, it's the

|
|
|
582 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
|
583 hard to auto-save all of your files before dying. (The main time that
|
|
|
584 this will not happen is if the machine physically lost power or if you
|
|
|
585 killed the XEmacs process using @samp{kill -9}.) The next time you
|
|
|
586 try to edit those files, you will be informed that a more recent
|
|
|
587 auto-save file exists. You can use @kbd{M-x recover-file} to retrieve
|
|
|
588 the auto-saved version of the file.
|
|
|
589
|
|
|
590 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
591 particular sequences of actions, that cause it to crash. If you can
|
|
|
592 come up with a reproducible way of doing this (or even if you have a
|
|
|
593 pretty good memory of exactly what you were doing at the time), the
|
|
|
594 maintainers would be very interested in knowing about it. Post a
|
|
|
595 message to @samp{comp.emacs.xemacs} or send mail to
|
|
|
596 @samp{xemacs@@cs.uiuc.edu}.
|
|
|
597
|
|
|
598 If at all possible, include a stack backtrace of the core dump that was
|
|
|
599 produced. This shows where exactly things went wrong, and makes it much
|
|
|
600 easier to diagnose problems. To do this, you need to locate the core
|
|
|
601 file (it's called @samp{core}, and is usually sitting in the directory
|
|
|
602 that you started XEmacs from, or your home directory if that other
|
|
|
603 directory was not writable). Then, go to that directory and execute a
|
|
|
604 command like
|
|
|
605
|
|
|
606 @example
|
|
|
607 gdb `which xemacs` core
|
|
|
608 @end example
|
|
|
609
|
|
|
610 and then issue the command @samp{where} to get the stack backtrace.
|
|
|
611 (You might have to use @samp{dbx} or some similar debugger in place
|
|
|
612 of @samp{gdb}. If you don't have any such debugger available,
|
|
|
613 complain to your system administrator.)
|
|
|
614
|
|
|
615 It's possible that a core file didn't get produced, in which case
|
|
|
616 you're out of luck. Go complain to your system administrator and
|
|
|
617 tell him not to disable core files by default. (If you explicitly
|
|
|
618 disabled core files, then double shame on you!)

641 There are two causes of this problem. The first usually only strikes
|
|

642 people using the prebuilt binaries. The culprit in both cases is the

645 @item
|

646 The binary cannot find the XKeysymDB file. The location is hardcoded at

647 compile time so if the system the binary was built on puts it a

|

648 different place than your system does, you have problems. To fix, set
|
|
|
649 the environment variable @samp{XKEYSYMDB} to the location of the
|
|
|
650 XKeysymDB file on your system or to the location of the one included
|

651 with XEmacs which should be at:
|
|
|
652
|

653 @example

660 administrator to replace it with the one which comes with XEmacs (which
|
|

|
|
|
668
|
|
|
669 This is highly dependent on your installation, but try with the
|
|
|
670 following font as your base font for XEmacs and see what it does:
|
|
|
671
|
|
|
672 @example
|
|
|
673 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
|
674 @end example
|
|
|
675
|
|
|
676 More precisely, do the following in your resource file:
|
|
|
677
|
|
|
678 @example
|
|
|
679 Emacs.default.attributeFont: -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1

726 There have been several reports of the X server locking up under Linux.
|

727 In all reported cases removing speedo and scaled fonts from the font

728 path corrected the problem. This can be done with the command 'xset'.

|
|
|
801

818 (fboundp 'foo)

|
0
|
819 @end example
|
|
70
|
820
|
|
|
821 It's always a mistake, under all circumstances, to test `emacs-version' or
|
|
|
822 any similar variables, in case they are not bound, unless you do the above.
|
|
|
823
|
|
|
824 Instead, use feature-tests, such as featurep or boundp or fboundp, or
|
|
|
825 even simple behavioural tests, eg
|
|
|
826 (defvar foo-old-losing-code? (condition-case nil (progn (losing-code t) nil)
|
|
|
827 (wrong-number-of-arguments t)))

828
|
|
|
829 There is an incredible amount of broken code out there which could
|

830 work much better more often in more places if it did the above instead

831 of trying to divine its environment from the value of one variable.

890 with all faces in the current mode by using M-x set-face-font (enter) ?.
|
|

891 It uses the face specification of "attributeFont", while menubar is a

|

892 normal X thing that uses the specification "font". With Motif it may be

893 necessary to use "fontList" instead of "font". (Please rewrite this if

|

894 you understand this better than me ... A general description of faces
|

895 would be very useful. I am just saying that menubar is a FAQ because

|
|
|
1039 is a convenience shorthand for the sequence @code{[(meta a)]}.
|
|
|
1040 @code{(global-set-key 'a 'foo)} means the same thing as
|
|
|
1041 @code{(global-set-key '[a] 'foo)}. It could be argued that allowing
|
|

1042 such a shorthand just leads to sloppiness and bugs, but it's there, and

1043 it isn't likely to go away.

1050 is typical FSF Emacs 19 brain damage. As is usual, an existing,

1054 @item "\ea"

1057 write code which works in every Emacs, but be aware that you can not

1058 express all Possible key-sequences (@kbd{control-9}, @kbd{f1}, etc.)

1121 The key point is that you can only bind simple functions to keys; you can not
|
|
|
1122 bind a key to a function that you're also passing arguments to. (See <A

|
|
|
1136 @end example
|
|
|
1137
|
|
|
1138 However, some modes explicitly bind @key{Delete}, so you would need to
|
|
|
1139 add a hook that does @code{local-set-key} for them.
|
|

1143 @section 8.7. How can I bind complex functions (or macros) to keys?
|
|
|
1144
|
|
|
1145 As an example, say you want the PASTE key on a Sun keyboard to insert the
|
|
|
1146 current Primary X selection at point. You can accomplish this with:
|
|
|
1147
|
|
|
1148 @example
|
|
|
1149 (define-key global-map 'f18 'x-insert-selection)
|
|
|
1150 @end example
|
|
|
1151
|
|
|
1152 However, this only works if there is a current X selection (the
|
|
|
1153 selection will be highlighted). The functionality I like is for the
|
|
|
1154 PASTE key to insert the current X selection if there is one, otherwise
|
|
|
1155 insert the contents of the clipboard. To do this you need to pass
|
|
|
1156 arguments to x-insert-selection. This is done by wrapping the call in a
|
|
|
1157 'lambda form:
|
|
|
1158
|
|
|
1159 @example
|
|
|
1160 (define-key global-map 'f18
|
|
|
1161 (function (lambda () (interactive) (x-insert-selection t nil))))
|
|
|
1162 @end example
|
|
|
1163
|
|
|
1164 This binds the 'f18 key to a "generic" functional object. The interactive
|
|
|
1165 spec is required because only interactive functions can be bound to keys.
|
|
|
1166 Also take a look at the doc for "function".
|
|
|
1167
|
|
|
1168 For the FAQ example you could use:
|
|
|
1169
|
|
|
1170 @example
|
|
|
1171 (global-set-key [(control ?.)]
|
|
|
1172 (function (lambda () (interactive) (scroll-up 1))))
|
|
|
1173 (global-set-key [(control ?;)]
|
|
|
1174 (function (lambda () (interactive) (scroll-up -1))))
|
|
|
1175 @end example
|
|
|
1176
|
|
|
1177 This is fine if you only need a few functions within the lambda body. If
|
|
|
1178 you're doing more it's cleaner to define a separate function as in the
|
|
|
1179 original FAQ example (<A HREF="#ss11.3">question 11.3</A>).

1329 common setting for Common Lisp programmers who use the bundled ilisp

1330 package, whereby meta-button1 on a function name will find the file

1332 the source file.

1411 you can see what area is being yanked. If you start working, though, it
|
|

1412 will immediately complete its operation. In other words, it will only

1413 delay for a second if you let it.

1444 @dfn{Pending delete} is what happens when you select a region (with the

1445 mouse or keyboard) and you press a key to replace the selected region by

1446 the key you typed. Usually backspace kills the selected region.

1694
|
|
|
1695 @samp{xemacs -name} sets the application-name for the program (that is,
|
|
|
1696 the thing which normally comes from @code{argv[0]}.) Using @samp{-name}
|
|
|
1697 is the same as making a copy of the executable with that new name. The
|
|
|
1698 WM_CLASS property on each frame is set to the frame-name, and the
|
|
|
1699 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
1700 created a frame named @samp{BAR}, you'd get an X window with WM_CLASS =
|
|
|
1701 @samp{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
1702 widget would be
|
|
|
1703
|
|
|
1704 @example
|
|
|
1705 Name: FOO .shell. .pane .BAR
|
|
|
1706 Class: Emacs.TopLevelShell.XmMainWindow.EmacsFrame
|
|
|
1707 @end example
|
|
|
1708
|
|
|
1709 instead of the default
|
|
|
1710
|
|
|
1711 @example
|
|
|
1712 Name: xemacs.shell. .pane .emacs
|
|
|
1713 Class: Emacs .TopLevelShell.XmMainWindow.EmacsFrame
|
|
|
1714 @end example
|
|
|
1715
|
|
|
1716 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
1717 application-name instead of the frame-name, but I think that's less
|
|
|
1718 flexible, since it does not give you the ability to have multiple
|
|
|
1719 frames with different WM_CLASS properties. Another possibility would
|
|
|
1720 be for the default frame name to come from the application name instead
|
|
|
1721 of simply being @samp{emacs}. However, at this point, making that
|
|
|
1722 change would be troublesome: it would mean that many users would have to
|
|
|
1723 make yet another change to their resource files (since the default
|
|
|
1724 frame name would suddenly change from @samp{emacs} to @samp{xemacs}, or
|
|
|
1725 whatever the executable happened to be named), so we'd rather avoid it.
|
|
|
1726
|
|
|
1727 To make a frame with a particular name use:
|
|
|
1728
|
|
|
1729 @example
|
|
|
1730 (make-frame '((name . "the-name")))

1752

1756

1757 or by having XEmacs automatically start it by adding lines like

|
|

1759 @example
|
|
16
|
1760 (add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock)

|
|
|
1770
|
|
|
1771 One way is to add, to @file{.emacs}:
|
|
|
1772
|
|
|
1773 @example
|
|
|
1774 (put 'if 'lisp-indent-function nil)
|
|
|
1775 @end example
|
|
|
1776
|
|
|
1777 However, note that the package @file{cl-indent.el} that comes with
|
|
|
1778 XEmacs sets up this kind of indentation by default. @file{cl-indent} also
|
|
|
1779 knows about many other CL-specific forms. To use @file{cl-indent}, one can
|
|
|
1780 do this:
|
|
|
1781
|
|
|
1782 @example
|
|
|
1783 (load "cl-indent")
|
|
|
1784 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
|
1785 @end example
|
|
|
1786
|
|
|
1787 One can also customize @file{cl-indent.el} so it mimics the default @samp{if}
|
|
|
1788 indentation (@samp{then} indented more than the @samp{else}). Here's
|
|
|
1789 how:
|
|
|
1790
|
|
|
1791 @example
|
|
|
1792 (put 'if 'common-lisp-indent-function '(nil nil &body))
|
|
|
1793 @end example
|
|
|
1794
|
|
|
1795 Also, a new version (1.2) of @file{cl-indent.el} was posted to
|
|
|
1796 @samp{comp.emacs.xemacs} on 12/9/94. This version includes more
|
|
|
1797 documentation than previous versions. This may prove useful if you
|
|
|
1798 need to customize any indent-functions. The post can be retrieved by
|
|
|
1799 searching the XEmacs mail archives.

|

1897 be in fundamental-mode. (Changing from fundamental-mode to auto-fill
|
|
|
1898 text-mode might not wreak too much havoc, but changing to something more
|
|
|
1899 exotic like a lisp-mode would break many Emacs packages.
|
|
|
1900
|
|
|
1901 Note that Emacs defaultly starts up in buffer *scratch* in
|
|
|
1902 initial-major-mode, which defaults to lisp-interaction-mode. Thus
|
|
|
1903 adding the following form to your Emacs init file will cause the
|
|
|
1904 initial *scratch* buffer to be put into auto-fill'ed text-mode.
|
|
|
1905
|
|
|
1906 @example
|
|
16
|
1907 (setq initial-major-mode
|

70
|
1908 (function (lambda ()
|

1913 Note that after your init file is loaded, if inhibit-startup-message
|
|
|
1914 is null (the default) and the startup buffer is *scratch* then the
|
|
|
1915 startup message will be inserted into *scratch*; it will be removed
|
|
|
1916 after a timeout by erasing the entire *scratch* buffer. Keep in mind
|
|
|
1917 this default usage of *scratch* if you desire any prior manipulation
|
|
|
1918 of *scratch* from within your Emacs init file. In particular, anything
|
|
|
1919 you insert into *scratch* from your init file will be later erased.
|
|
|
1920 Also, if you change the mode of *scratch* be sure that this will
|
|
|
1921 not interfere with possible later insertion of the startup message
|
|
|
1922 (e.g. if you put *scratch* into a nonstandard mode that has automatic
|
|
|
1923 font lock rules, then the startup message might get fontified in
|
|
|
1924 a strange foreign manner, e.g. as code in some programming language).

1947

1948 This will then start a second shell. The key is that no buffer named

70

1949 *shell* can exist. It might be preferable to use @kbd{M-x

1964 If you see lots of ^G's in the buffer, you're using an old version of

1966 you are probably using csh with the @samp{filec} variable set. To fix

2198
|

|
2199 You can specify what paths to use by using a number of different flags
|
|
|
2200 when running configure. See the section MAKE VARIABLES in the top-level
|
|
|
2201 file INSTALL in the XEmacs distribution for a listing of those flags.
|
|
|
2202
|
|
70
|
2203 Most of the time, however, the simplest fix is: DO NOT specify paths as
|
|
|
2204 you might for FSF GNU Emacs. XEmacs can generally determine the
|
|
0
|
2205 necessary paths dynamically at run time. The only path that generally
|
|
|
2206 needs to be specified is the root directory to install into. That can
|
|
|
2207 be specified by passing the @code{--prefix} flag to configure. For a
|
|
70

2208 description of the XEmacs install tree, please consult the NEWS file.

2214 We don't know, but you can use tpu-edt emulation instead, which works fine
|
|

2215 and is a little fancier than the standard edt emulation. To do this, add

2251 @section 22.4. Is there some way to get the behavior so that if the current buffer has a file associated with it, the current buffer will use that files name else use the buffer name?
|
|
|
2252
|
|
|
2253 Just set frame-title-format from find-file-hooks. Alternatively, look at
|
|
|
2254 the answer to question 15.2.
|
|
|
2255
|
|
|
2256 In addition, one could set modeline-format.

2260 @section 22.5. I have no idea where this is coming from, but ever since I moved from 19.9 to 19.13 I have started seeing that all of my buffers will get a minor mode called @samp{Omit}. I have no idea how it got there nor do I know what it does. What is it?
|
|
|
2261
|
|
|
2262 It's part of dired. In dired, you can type M-o to get Omit mode and that will
|
|
|
2263 ignore uninteresting files (checkpoint files and backups, for example). You
|
|
|
2264 get Omit in the modeline everywhere because the variable `dired-omit-files-p'
|
|
|
2265 is globally set to some non-nil value. If you want this functionality, it's
|
|
|
2266 probably best to use a hook:
|
|
|
2267
|
|
|
2268 @example
|
|
|
2269 (add-hook 'dired-after-readin-hook '(lambda () (dired-omit-toggle)))
|
|
|
2270 @end example
|
|
|
2271
|
|
|
2272 Alternatively, since it seems odd to toggle the omit
|
|
|
2273 state with every readin, since readin can happen many times in a Dired
|
|
|
2274 buffer, you can try this hook to correct the "Omit" problem:
|
|
0
|
2275
|
|
|
2276 @example
|
|
70
|
2277 (add-hook 'dired-mode-hook
|
|
|
2278 (function (lambda ()
|
|
|
2279 ;; `dired-omit-files-p' is made buffer-local by "dired-x.el", but
|
|
|
2280 ;; maybe not soon enough.
|
|
|
2281 (make-local-variable 'dired-omit-files-p)
|
|
|
2282 (setq dired-omit-files-p t))))
|
|
|
2283 @end example
|
|
|
2284
|
|
|
2285 This is only run once, when the Dired buffer is created.

2289 @section 22.6. How do I turn off the sound?
|
|
|
2290
|
|
|
2291 Add the following line to your @file{.emacs} file:
|
|
|
2292
|
|
|
2293 @example
|
|
|
2294 (setq bell-volume 0)
|
|
|
2295 (setq sound-alist nil)
|

|

2300 @section 22.7. Can I have the end of the buffer delimited in some way? Say, with: [END] ?
|
|
|
2301
|
|
|
2302 @example
|
|
|
2303 (make-annotation "[END]" (point-max) 'text (current-buffer))
|
|
|
2304 @end example
|
|
|
2305
|
|
|
2306 Note that you might want to put this in a hook.
|
|
|
2307
|
|
|
2308 You might also need:
|
|
|
2309
|
|
|
2310 @example
|
|
|
2311 (require 'annotations)
|
|
0
|
2312 @end example
|
|
|
2313
|
|
70
|
2314 since @code{make-annotation} is not defined by default.

2320 Use this lisp in a function:
|
|
|
2321
|
|
|
2322 @example
|
|
|
2323 (insert (current-time-string))
|

2328 @section 22.9. Are only certain syntactic character classes available for abbrevs? I didn't see any restrictions in the info.
|
|
|
2329
|
|
|
2330 Yes, abbrevs only expand word-syntax strings. So, in c-mode if you
|
|
|
2331 wanted to expand something to @samp{define }, you would be able to
|
|
|
2332 expand @samp{xd} but not @samp{#d}.

2336 @section 22.10. Filladapt used to work after I loaded it. Now in 19.13 it doesn't. What gives?
|
|
|
2337
|
|
|
2338 Filladapt 2.x is included in 19.13+. In it filladapt is now a minor
|
|
|
2339 mode and minor modes are traditionally off by default. The following
|
|
|
2340 added to your .emacs will turn it on for all buffers:
|
|
|
2341
|
|
|
2342 @example
|
|
|
2343 (setq-default filladapt-mode t)
|
|
|
2344 @end example
|
|
|
2345
|
|
|
2346 Use @code{turn-on-filladapt-mode} to turn Filladapt on in particular
|
|
|
2347 major modes, like this:
|
|
|
2348
|
|
|
2349 @example
|
|
|
2350 (add-hook 'text-mode-hook 'turn-on-filladapt-mode)
