52 Learning XEmacs is a lifelong activity. I've been using Emacs for
|
|
|
53 over a decade now, and I'm still discovering new features. Therefore
|
|
|
54 this document cannot be complete. Instead it is aimed at the person
|
|
|
55 who is either considering XEmacs for their own use, or has just
|
|
|
56 obtained it and is wondering what to do next. It is also useful as a
|
|
|
57 reference to available resources.

59 The previous maintainer of the FAQ was Anthony Rossini
|
|
|
60 <rossini@@stat.sc.edu>, who started it, after getting tired of hearing
|
|
|
61 JWZ complain about repeatedly having to answer questions. Ben Wing
|
|
|
62 <ben@@666.com> and Chuck Thompson <cthomp@@xemacs.org>, the principal
|
|
|
63 authors of XEmacs, then took over and Ben did a massive update
|
|
|
64 reorganizing the whole thing. At which point Anthony took back over,
|
|
|
65 but then had to give it up again. Some of the other contributors to
|
|
|
66 this FAQ are listed later in this document.

72 Since Steve Baur is so busy putting out multiple versions of XEmacs I
|
|
|
73 have taken on the task of maintaining the FAQ. I use XEmacs on a daily
|
|
|
74 basis and I wanted to give something back to the community that has made
|
|
|
75 XEmacs possible. If you notice any errors or items which should be
|
|
|
76 added or amended to this FAQ please send email to Andreas Kaempf

128 An alternative to GNU Emacs, originally based on an early alpha version

82
|
129 of FSF's version 19, and has diverged quite a bit since then. XEmacs
|

130 was known as Lucid Emacs through version 19.10. Almost all features of
|

131 GNU Emacs are supported in XEmacs The maintainers of XEmacs actively

137 The current stable version of XEmacs is 20.2, released in May, 1997.

138 The next feature release will XEmacs 20.3.
|
|

140 XEmacs 19.15 was the last release of v19, released in March, 1997.
|
|
|
141
|
|
|
142 To help users who are not yet ready to move to XEmacs 20, we run a
|
|
|
143 patch-page with official bugfixes for 19.15 at:
|
|
|
144
|
|
|
145 @example

|
|
|
148
|
|
|
149 The page is maintained by Vinnie Shelton @code{<acs@@acm.org>}. These
|
|
|
150 fixes will be integrated to a XEmacs and released as 19.16, which would
|
|
|
151 serve as stable XEmacs until 20.x settles completely.

509 XEmacs v20 is the version of XEmacs that includes MULE (Asian-language)

163
|
510 support. XEmacs 20.0 was released in February 1997, followed by XEmacs
|
|
|
511 20.2 in May. When compiled without MULE support 20.2 is currently very
|
|
|
512 similar to 19.15 (except for some changes to the byte-code format, some
|
|
|
513 new primitive types including @code{char}, @code{char-table}, and
|
|
|
514 @code{range-table}) and equally stable.

540 Emacs*XlwMenu.resourceLabels: True

544

556 Original Mule supports following input methods: Wnn4, Wnn6, Canna, SJ3
|
|
|
557 and XIM. Interfaces for Wnn and SJ3 uses the @code{egg} user
|
|
|
558 interface. Interface for Canna does not use @samp{egg}. I don't know
|
|
|
559 about XIM. It is to support ATOK, of course, it may work for another
|
|
|
560 servers.
|
|
|
561
|
|
|
562 Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
|
|
|
563 university. It is a powerful and complex system. Wnn4 is free and Wnn6
|
|
|
564 is not free.
|
|
|
565
|
|
|
566 Canna supports only Japanese. It is made by NEC. It is a simple and
|
|
|
567 powerful system. Canna uses only grammar (Wnn uses grammar and
|
|
|
568 probability between words), so I think Wnn is cleverer than Canna,
|
|
|
569 however Canna users made a good grammar and dictionary. So for standard
|
|
|
570 modern Japanese, Canna seems cleverer than Wnn4. In addition, the UNIX
|
|
|
571 version of Canna is free (now there is a Microsoft Windows version).
|
|
|
572
|
|
|
573 SJ3 supports only Japanese. It is made by Sony. XIM supports was made
|
|
|
574 to use ATOK (a major input method in personal computer world). XIM is
|
|
|
575 the standard for accessing input methods bundled in Japanese versions of
|
|
|
576 Solaris. (XEmacs 20 will support XIM input).

578 Egg consists of following parts:

579
|
|
|
580 @enumerate
|
|
|
581 @item Input character Translation System (ITS) layer.
|
|
|
582 It translates ASCII inputs to Kana/PinYin/Hangul characters.
|
|
|
583
|
|
|
584 @item Kana/PinYin/Hangul to Kanji transfer layer.
|
|
126
|
585 It is interface layer for network Kana-Kanji server (Wnn and Sj3).
|
|
82
|
586 @end enumerate
|
|
|
587
|
|
|
588 These input methods are modal, namely there are mode, alphabet mode and
|
|
|
589 Kana-Kanji transfer mode. However there are mode-less input methods for
|
|
|
590 Egg and Canna. @samp{Boiled-egg} is a mode-less input method running on
|
|
|
591 Egg. For Canna, @samp{canna.el} has a tiny boiled-egg like command,
|
|
|
592 @code{(canna-boil)}, and there are some boiled-egg like utilities. In
|
|
|
593 addition, it was planned to make an abstraction for all transfer type
|
|
|
594 input methods. However authors of input methods are busy, so maybe this
|
|
|
595 plan is stopped. Perhaps after Mule merged GNU Emacs will be released,
|
|

596 it will be continued.

605 MULE and XEmacs are quite different. So the application

607

|

671
|
|
|
672 The @file{.emacs} file is used to customize XEmacs to your tastes. No
|
|
|
673 two are alike, nor are they expected to be alike, but that's the point.
|
|
|
674 The XEmacs distribution contains an excellent starter example in the etc
|
|
|
675 directory called @file{sample.emacs}. Copy this file from there to your
|
|
|
676 home directory and rename it @file{.emacs}. Then edit it to suit.
|
|
|
677
|
|
|
678 Starting with 19.14, you may bring the @file{sample.emacs} into an
|
|
|
679 XEmacs buffer by selecting @samp{Help->Sample .emacs} from the menubar.
|
|
|
680 To determine the location of the @file{etc} directory type the command
|
|
|
681 @kbd{C-h v data-directory RET}.

|
|
|
706
|
|
|
707 The following function does a little bit of everything useful. It does
|
|
|
708 something with the prefix argument, it examines the text around the
|
|
|
709 cursor, and it's interactive so it may be bound to a key. It inserts
|
|
|
710 copies of the current word the cursor is sitting on at the cursor. If
|
|
|
711 you give it a prefix argument: @kbd{C-u 3 M-x double-word} then it will
|
|
|
712 insert 3 copies.
|
|
|
713
|
|
|
714 @lisp
|
|
|
715 (defun double-word (count)
|
|
|
716 "Insert a copy of the current word underneath the cursor"
|
|
|
717 (interactive "*p")
|
|
|
718 (let (here there string)
|
|
|
719 (save-excursion
|
|
|
720 (forward-word -1)
|
|
|
721 (setq here (point))
|

|
722 (forward-word 1)
|
|

723 (setq there (point))

|
|
724 (setq string (buffer-substring here there)))
|

725 (while (>= count 1)

|

|
729
|
|
|
730 The best way to see what is going on here is to let XEmacs tell you.
|
|
|
731 Put the code into an XEmacs buffer, and do a @kbd{C-h f} with the cursor
|
|
|
732 sitting just to the right of the function you want explained. Eg. move
|
|
|
733 the cursor to the SPACE between @code{interactive} and @samp{"*p"} and
|
|
|
734 hit @kbd{C-h f} to see what the function @code{interactive} does. Doing
|
|
|
735 this will tell you that the @code{*} requires a writable buffer, and
|
|
|
736 @code{p} converts the prefix argument to a number, and
|
|
|
737 @code{interactive} allows you to execute the command with @kbd{M-x}.

757 @section What's the difference between a macro and a function?
|
|
|
758
|
|
163
|
759 Quoting from the Lisp Reference (a.k.a @dfn{Lispref}) Manual:
|
|
82
|
760
|
|
|
761 @dfn{Macros} enable you to define new control constructs and other
|
|
|
762 language features. A macro is defined much like a function, but instead
|
|
|
763 of telling how to compute a value, it tells how to compute another Lisp
|
|
|
764 expression which will in turn compute the value. We call this
|
|
|
765 expression the @dfn{expansion} of the macro.
|
|
|
766
|
|
|
767 Macros can do this because they operate on the unevaluated expressions
|
|
|
768 for the arguments, not on the argument values as functions do. They can
|
|
|
769 therefore construct an expansion containing these argument expressions
|
|
|
770 or parts of them.
|
|
|
771
|
|
163
|
772 Do not confuse the two terms with @dfn{keyboard macros}, which are
|
|
|
773 another matter, entirely. A keyboard macro is a key bound to several
|
|
|
774 other keys. Refer to manual for details.

784 @end lisp

786 saved by a 19.13 XEmacs that causes a 19.14 XEmacs grief. You must

126
|
787 delete these options. XEmacs 19.14 and later no longer write the
|
|
|
788 options directly to @file{.emacs} which should allow us to deal with
|
|
|
789 version incompatibilities better in the future.
|
|
82
|
790
|

|
791 Options saved under XEmacs 19.13 are protected by code that specifically

792 requires a version 19 XEmacs. This won't be a problem unless you're

794

796 (cond

|
857
|
|
|
858 The @file{INSTALL} file says that up to 108 MB of space is needed
|
|
|
859 temporarily during installation! How can I just try it out?
|
|
|
860
|
|
|
861 XEmacs will run in place without requiring installation and copying of
|
|
|
862 the Lisp directories, and without having to specify a special build-time
|
|
|
863 flag. It's the copying of the Lisp directories that requires so much
|
|
|
864 space. XEmacs is largely written in Lisp.
|
|
|
865
|
|
|
866 A good method is to make a shell alias for xemacs:
|
|
|
867
|
|
|
868 @example
|
|
163
|
869 alias xemacs=/i/xemacs-20.2/src/xemacs
|
|
82
|
870 @end example
|
|
|
871
|
|
|
872 (You will obviously use whatever directory you downloaded the source
|
|
163
|
873 tree to instead of @file{/i/xemacs-20.2}).
|
|
82
|
874
|
|
|
875 This will let you run XEmacs without massive copying.

883 The 45MB of space required by the installation directories can be
|
|
|
884 reduced dramatically if desired. Gzip all the .el files. Remove all
|
|
|
885 the packages you'll never want to use (or even ones you do like the two
|
|
|
886 obsolete mailcrypts and Gnus 4 in 19.13). Remove the TexInfo manuals.
|
|
|
887 Remove the Info (and use just hardcopy versions of the manual). Remove
|
|
|
888 most of the stuff in etc. Remove or gzip all the source code. Gzip or
|
|
|
889 remove the C source code. Configure it so that copies are not made of
|
|
|
890 the support lisp. I'm not advocating any of these things, just pointing
|
|
|
891 out ways to reduce the disk requirements if desired.
|
|
|
892
|
|
|
893 Now examine the space used by directory:
|
|
|
894
|
|
|
895 @example
|
|
|
896 0 /usr/local/bin/xemacs
|
|
|
897 2048 /usr/local/bin/xemacs-19.13
|

|
|
|
901 @end example
|
|
|
902
|
|
|
903 You need to keep these. XEmacs isn't stripped by default in
|
|
|
904 installation, you should consider stripping. That will save you about
|
|
|
905 5MB right there.
|
|
|
906
|
|
|
907 @example
|
|
|
908 207 /usr/local/lib/xemacs-19.13/etc/w3

|
|
909 122 /usr/local/lib/xemacs-19.13/etc/sounds

919 These are support directories for various packages. In general they
|
|
|
920 match a directory under ./xemacs-19.13/lib/xemacs-19.13/lisp/. If you

921 do not require the package, you may delete or gzip the support too.

970 These are all Emacs Lisp source code and bytecompiled object code. You
|
|
|
971 may safely gzip everything named *.el here. You may remove any package
|
|
|
972 you don't use. @emph{Nothing bad will happen if you delete a package
|
|
|
973 that you do not use}. You must be sure you do not use it though, so be

974 conservative at first.
|
|
|
975
|
|
|
976 Possible candidates for deletion include w3 (newer versions exist, or
|
|

977 you may just use Lynx or Netscape for web browsing), games, hyperbole,

978 mh-e, hm--html-menus (better packages exist), vm, viper, oobr, gnus (new

980 package?} If the answer is no, then it is a candidate for removal.
|
|
|
981
|
|
|
982 First, gzip all the .el files. Then go about package by package and
|
|
|
983 start gzipping the .elc files. Then run XEmacs and do whatever it is
|
|
|
984 you normally do. If nothing bad happens, then delete the directory. Be
|
|
|
985 conservative about deleting directories, and it would be handy to have a

|

986 backup tape around in case you get too zealous.

1053 @section Compiling XEmacs with Netaudio.
|
|
|
1054
|
|
|
1055 What is the best way to compile XEmacs with the netaudio system, since I
|
|
|
1056 have got the netaudio system compiled but installed at a weird place, I
|
|
|
1057 am not root. Also in the READMEs it does not say anything about
|
|
|
1058 compiling with the audioserver?
|
|
|
1059
|
|
|
1060 You should only need to add some stuff to the configure command line.
|
|
|
1061 To tell it to compile in netaudio support: @samp{--with-sound=both}, or
|
|
|
1062 @samp{--with-sound=nas} if you don't want native sound support for some
|
|
|
1063 reason.) To tell it where to find the netaudio includes and libraries:
|
|
16
|
1064
|
|
|
1065 @example
|
|
82
|
1066 --site-libraries=WHATEVER
|
|
|
1067 --site-includes=WHATEVER
|
|
|
1068 @end example
|
|
|
1069
|
|
|
1070 Then (fingers crossed) it should compile and it will use netaudio if you
|
|
|
1071 have a server running corresponding to the X server. The netaudio server
|
|
|
1072 has to be there when XEmacs starts. If the netaudio server goes away and
|
|
|
1073 another is run, XEmacs should cope (fingers crossed, error handling in
|
|
|
1074 netaudio isn't perfect).
|
|
|
1075
|
|
|
1076 BTW, netaudio has been renamed as it has a name clash with something
|
|
|
1077 else, so if you see references to NAS or Network Audio System, it's the
|
|
|
1078 same thing. It also might be found at

1246 That's correct [The SunOS 4.1.3 precompiled binaries don't do name
|
|
|
1247 lookup]. Since Sun figured that everyone used NIS to do name lookups
|
|
|
1248 (that DNS thing was apparently only a passing fad, right?), the stock
|
|
|
1249 SunOS 4.x systems don't have DNS-based name lookups in libc.
|
|
|
1250
|
|
|
1251 This is also why Netscape ships two binaries for SunOS 4.1.x.
|
|
|
1252
|
|
|
1253 The best solution is to compile it yourself; the configure script will
|
|
|
1254 check to see if you've put DNS in the shared libc and will then proceed
|
|
|
1255 to link against the DNS resolver library code.

1264 Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
|
|
|
1265 link gives you a bare-boned emacs (called temacs). temacs is then run,
|
|
|
1266 preloading some of the lisp files. The result is then dumped into a new
|
|
|
1267 executable, named xemacs, which will contain all of the preloaded lisp
|
|
|
1268 functions and data.
|
|
|
1269
|
|
|
1270 Now, during the dump itself, the executable (code+data+symbols) is
|
|
|
1271 written on disk using a special unexec() function. This function is
|
|
|
1272 obviously heavily system dependent. And on some systems, it leads to an
|
|
|
1273 executable which, although valid, cannot be stripped without damage. If
|
|
|
1274 memory serves, this is especially the case for AIX binaries. On other
|
|
|
1275 architecture it might work OK.
|
|
|
1276
|
|
|
1277 The Right Way to strip the emacs binary is to strip temacs prior to
|
|
|
1278 dumping xemacs. This will always work, although you can do that only if
|
|
|
1279 you install from sources (as temacs is @file{not} part of the binary
|
|
|
1280 kits).

1349 @section Help! XEmacs just crashed on me!
|

|
1350
|
|
|
1351 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
163
|
1352 hard to auto-save all of your files before dying. (The main time that
|
|
82
|
1353 this will not happen is if the machine physically lost power or if you
|
|
163
|
1354 killed the XEmacs process using @code{kill -9}). The next time you try
|
|
82
|
1355 to edit those files, you will be informed that a more recent auto-save
|
|
|
1356 file exists. You can use @kbd{M-x recover-file} to retrieve the
|
|
|
1357 auto-saved version of the file.
|
|
|
1358
|
|
|
1359 Starting with 19.14, you may use the command @kbd{M-x recover-session}
|
|
|
1360 after a crash to pick up where you left off.
|
|
|
1361
|
|
|
1362 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
1363 particular sequences of actions, that cause it to crash. If you can
|
|
|
1364 come up with a reproducible way of doing this (or even if you have a
|
|
|
1365 pretty good memory of exactly what you were doing at the time), the
|
|
|
1366 maintainers would be very interested in knowing about it. Post a
|
|
|
1367 message to comp.emacs.xemacs or send mail to <crashes@@xemacs.org>.
|
|
|
1368 Please note that the @samp{crashes} address is exclusively for crash
|
|
|
1369 reports.
|
|
|
1370
|
|
|
1371 If at all possible, include a stack backtrace of the core dump that was
|
|
|
1372 produced. This shows where exactly things went wrong, and makes it much
|
|
|
1373 easier to diagnose problems. To do this, you need to locate the core
|
|
|
1374 file (it's called @file{core}, and is usually sitting in the directory
|
|
|
1375 that you started XEmacs from, or your home directory if that other
|
|
|
1376 directory was not writable). Then, go to that directory and execute a
|
|
|
1377 command like:
|
|
|
1378
|
|
|
1379 @example
|
|
|
1380 gdb `which xemacs` core
|
|
|
1381 @end example
|
|
|
1382
|
|
|
1383 and then issue the command @samp{where} to get the stack backtrace. You
|
|
|
1384 might have to use @code{dbx} or some similar debugger in place of
|
|
|
1385 @code{gdb}. If you don't have any such debugger available, complain to
|
|
|
1386 your system administrator.
|
|
|
1387
|
|
|
1388 It's possible that a core file didn't get produced, in which case you're
|
|
|
1389 out of luck. Go complain to your system administrator and tell him not
|
|
|
1390 to disable core files by default. Also @xref{Q2.1.15} for tips and
|
|

1464 set the environment variable @var{XKEYSYMDB} to the location of the

1568 What fixed the problem was adding some more colors to the X color

1578 resources are not defined.

1580 If the new colours are not present then an additional error occurs on

1720 If XEmacs does crash on you, one of the most productive things you can
|
|
|
1721 do to help get the bug fixed is to poke around a bit with the debugger.
|
|
|
1722 Here are some hints:

1723
|
|

1724 @itemize @bullet

1725 @item
|
|
|
1726 First of all, if the crash is at all reproducible, consider very
|
|
|
1727 strongly recompiling your XEmacs with debugging symbols, with no
|
|
|
1728 optimization, and with the configure options @samp{--debug=yes},
|
|
|
1729 @samp{--error-checking=all}, and @samp{--dynamic=no}. This will make
|
|
|
1730 your XEmacs run somewhat slower but make it a lot more likely to catch
|
|
|
1731 the problem earlier (closer to its source), and a lot easier to
|
|
|
1732 determine what's going on with a debugger.
|
|
|
1733
|
|
|
1734 @item
|
|
|
1735 If you're able to run XEmacs under a debugger and reproduce the crash
|
|
|
1736 (if it's inconvenient to do this because XEmacs is already running or is
|
|
|
1737 running in batch mode as part of a bunch of scripts, consider attaching
|
|
|
1738 to the existing process with your debugger; most debuggers let you do
|
|
|
1739 this by substituting the process ID for the core file when you invoke
|
|
|
1740 the debugger from the command line, or by using the @code{attach}
|
|
|
1741 command or something similar), here are some things you can do:
|
|
|
1742
|
|
|
1743 @item
|
|
|
1744 If XEmacs is hitting an assertion failure, put a breakpoint on
|
|
|
1745 @code{assert_failed()}.
|
|
|
1746
|
|
|
1747 @item
|
|
|
1748 If XEmacs is hitting some weird Lisp error that's causing it to crash
|
|
|
1749 (e.g. during startup), put a breakpoint on @code{signal_1()}---this is
|
|
|
1750 declared static in eval.c.
|
|
|
1751
|
|
|
1752 @item
|
|
|
1753 Internally, you will probably see lots of variables that hold objects of
|
|
|
1754 type @code{Lisp_Object}. These are exactly what they appear to be,
|
|
|
1755 i.e. references to Lisp objects. Printing them out with the debugger
|
|
|
1756 probably won't be too useful---you'll just see a number. To decode
|
|
|
1757 them, do this:
|
|
|
1758
|
|
|
1759 @example
|
|
|
1760 call debug_print (OBJECT)
|
|
|
1761 @end example
|
|
|
1762
|
|
|
1763 where @var{OBJECT} is whatever you want to decode (it can be a variable,
|
|
|
1764 a function call, etc.). This will print out a readable representation
|
|
|
1765 on the TTY from which the xemacs process was invoked.
|
|
|
1766
|
|
|
1767 @item
|
|
|
1768 If you want to get a Lisp backtrace showing the Lisp call
|
|
|
1769 stack, do this:
|
|
|
1770
|
|
|
1771 @example
|
|
|
1772 call debug_backtrace ()
|
|
|
1773 @end example
|
|
|
1774
|
|
|
1775 @item
|
|
|
1776 If all you've got is a core dump, all is not lost. You can still poke
|
|
|
1777 around somewhat, and if you're using GDB, there are some macros in the
|
|
|
1778 file @file{gdbinit} in the @file{src} directory of the XEmacs
|
|
|
1779 distribution that should make it easier for you to decode Lisp objects.

1786 If you're using a debugger to get a C stack backtrace and you're seeing
|
|
|
1787 stack traces with some of the innermost frames mangled, it may be due to
|
|
|
1788 dynamic linking. (This happens especially under Linux.) Consider
|
|
|
1789 reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
|
|
|
1790 Linux), stack backtraces of core dumps will have the frame where the
|
|
|
1791 fatal signal occurred mangled; if you can obtain a stack trace while
|
|
|
1792 running the XEmacs process under a debugger, the stack trace should be
|
|
|
1793 clean.

1799 If you're using a debugger to get a C stack backtrace and you're

|
|
1800 getting a completely mangled and bogus stack trace, it's probably due to
|
|
|
1801 one of the following:

|
|

1806 do this---it doesn't accomplish anything except to save a bit of disk
|
|
|
1807 space, and makes debugging much much harder.
|
|
|
1808
|
|
|
1809 @item
|
|
|
1810 Your stack is getting trashed. Debugging this is hard; you have to do a
|
|
|
1811 binary-search-type of narrowing down where the crash occurs, until you
|
|
|
1812 figure out exactly which line is causing the problem. Of course, this
|
|
|
1813 only works if the bug is highly reproducible.
|
|
|
1814
|
|
|
1815 @item
|
|
|
1816 If your stack trace has exactly one frame in it, with address 0x0, this
|
|
|
1817 could simply mean that XEmacs attempted to execute code at that address,
|
|
|
1818 e.g. through jumping to a null function pointer. Unfortunately, under
|
|
|
1819 those circumstances, GDB under Linux doesn't know how to get a stack
|
|
|
1820 trace. (Yes, this is the third Linux-related problem I've mentioned. I
|
|
|
1821 have no idea why GDB under Linux is so bogus. Complain to the GDB
|
|
|
1822 authors, or to comp.os.linux.development.system). Again, you'll have to
|
|
|
1823 use the narrowing-down process described above.

1826 If you compiled 19.14 with @samp{--debug} (or by default in later
|

1827 versions), you will get a Lisp backtrace output when XEmacs crashes, so
|
|
|
1828 you'll have something useful. If you're in 19.13, you could try doing
|
|
|
1829 @code{call debug_backtrace()}---sometimes this works even after a fatal
|
|
|
1830 signal has been received.

1835 Here's some more info about using gdbinit:
|
|
|
1836
|
|
|
1837 Different version of @code{gdbinit} are provided for different
|
|
|
1838 platforms. One of these should be installed as @file{.gdbinit} in your
|
|
|
1839 home directory. If you're using XEmacs 19.14 or better, you should
|
|
|
1840 install the default @code{gdbinit} in the @file{src/} directory if you
|
|
|
1841 have GDB 4.14 or better. With GDB 4.13 or earlier, install
|
|
|
1842 @file{gdbinit.pre-4.14}; however, this is noticeably harder to use. If
|
|
|
1843 you're on a machine that uses a union type for Lisp_Objects (only the
|
|
|
1844 DEC Alpha, I think), you'll have to use @code{gdbinit.union}, which is
|
|
|
1845 of the pre-4.14 variety but should be easily upgradable.
|
|
|
1846
|
|
|
1847 With XEmacs 19.13 and earlier, only one @code{gdbinit} is provided (I
|
|
|
1848 think); it's of the pre-4.14 variety and of the union-type
|
|
|
1849 variety. (Many more machines used the union type under 19.13).
|
|
|
1850
|
|
|
1851 With the GDB 4.14+ gdbinit, you can print out a Lisp_Object using
|
|
|
1852 @code{p1 OBJECT} (which calls @code{debug_print()}, and hence only works
|
|
|
1853 if you have a running process) or @code{frob OBJECT} (which works even
|
|
|
1854 on core dumps, and does its own decoding of the object, but its output
|
|
|
1855 isn't always so convenient).
|
|
|
1856
|
|
|
1857 With the pre-GDB 4.14 gdbinit, you have to do these steps:
|
|
|
1858
|
|
|
1859 @example
|
|
|
1860 print OBJECT
|
|
|
1861 xtype
|
|
|
1862 <then type "xcons" or "xstring" or whatever, depending on the type>
|
|
|
1863 @end example
|
|
|
1864
|
|
|
1865 If the object is a record type, you'll probably have to the following
|
|
|
1866 steps:
|
|
|
1867
|
|
|
1868 @example
|
|
|
1869 print OBJECT
|
|
|
1870 xtype
|
|
|
1871 xrecord
|
|
|
1872 <remember what type is printed>
|
|
|
1873 print OBJECT
|
|
|
1874 <then type "xbuffer" or "xsymbol" or whatever>
|
|
|
1875 @end example
|
|
|
1876
|
|
|
1877 Of course, if you know in advance what type the object is of, you can
|
|
|
1878 omit all but the last two steps.

1927 For the record, compiling on hpux 10.10 leads to a hang in Gnus when
|
|
|
1928 compiled with optimization on.
|
|
|
1929
|
|
|
1930 I've just discovered that my hpux 10.01 binary was working less well
|
|
|
1931 than expected. In fact, on a 10.10 system, @code{(while t)} was not
|
|
|
1932 interupted by @kbd{C-g}. I defined @code{BROKEN_SIGIO} and recompiled on
|
|
|
1933 10.10, and... the hang is now gone.
|
|
|
1934
|
|
|
1935 As far as configure goes, this will be a bit tricky: @code{BROKEN_SIGIO}
|
|
|
1936 is needed on 10.10, but @strong{not} on 10.01: if I run my 10.01 binary
|
|
|
1937 on a 10.01 machine, without @code{BROKEN_SIGIO} being defined, @kbd{C-g}
|
|
|
1938 works as expected.

1944 Apparently somebody has found the reason why there is this @samp{poll:
|
|
|
1945 interrupted...} message for each event. For some reason, libcurses
|
|
|
1946 reimplements a @code{select()} system call, in a highly broken fashion.
|
|
|
1947 The fix is to add a -lc to the link line @emph{before} the
|
|
|
1948 -lxcurses. XEmacs will then use the right version of @code{select()}.

2008 Two things you can do:
|
|
|
2009
|
|
|
2010 1) C level:
|
|
|
2011
|
|
|
2012 When you see it going mad like this, you might want to use gdb from an
|
|
|
2013 'xterm' to attach to the running process and get a stack trace. To do
|
|
|
2014 this just run:
|
|
|
2015
|
|
|
2016 @example
|
|
|
2017 gdb /path/to/xemacs/xemacs ####
|
|
|
2018 @end example
|
|
|
2019
|
|
163
|
2020 Where @code{####} is the process id of your xemacs, instead of
|
|
|
2021 specifying the core. When gdb attaches, the xemacs will stop [1] and
|
|
|
2022 you can type `where' in gdb to get a stack trace as usual. To get
|
|
|
2023 things moving again, you can just type `quit' in gdb. It'll tell you
|
|
|
2024 the program is running and ask if you want to quit anyways. Say 'y' and
|
|
|
2025 it'll quit and have your emacs continue from where it was at.
|
|
116
|
2026
|
|
|
2027 2) Lisp level:
|
|
|
2028
|
|
|
2029 Turn on debug-on-quit early on. When you think things are going slow
|
|
|
2030 hit C-g and it may pop you in the debugger so you can see what routine
|
|
|
2031 is running. Press `c' to get going again.
|
|
|
2032
|
|
|
2033 debug-on-quit doesn't work if something's turned on inhibit-quit or in
|
|
|
2034 some other strange cases.

2395
|
|
|
2396 When I run @samp{xterm -name junk}, I get an xterm whose class name
|
|
|
2397 according to xprop, is @samp{junk}. This is the way it's supposed to
|
|
|
2398 work, I think. When I run @samp{xemacs -name junk} the class name is
|
|
|
2399 not set to @samp{junk}. It's still @samp{emacs}. What does
|
|
|
2400 @samp{xemacs -name} really do? The reason I ask is that my window
|
|
|
2401 manager (fvwm) will make a window sticky and I use XEmacs to read my
|
|
|
2402 mail. I want that XEmacs window to be sticky, without having to use the
|
|
|
2403 window manager's function to set the window sticky. What gives?
|
|
|
2404
|
|
|
2405 @samp{xemacs -name} sets the application name for the program (that is,
|
|
|
2406 the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
|
|
|
2407 is the same as making a copy of the executable with that new name. The
|
|
|
2408 @code{WM_CLASS} property on each frame is set to the frame-name, and the
|
|
|
2409 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
2410 created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
|
|
|
2411 @code{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
2412 widget would be:
|
|
|
2413
|
|
|
2414 @example
|
|
|
2415 Name: FOO .shell .container .BAR
|
|
|
2416 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2417 @end example
|
|
|
2418
|
|
|
2419 instead of the default
|
|
|
2420
|
|
|
2421 @example
|
|
|
2422 Name: xemacs.shell .container .emacs
|
|
|
2423 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2424 @end example
|
|
|
2425
|
|
|
2426
|
|
|
2427 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
2428 application-name instead of the frame-name, but I think that's less
|
|
|
2429 flexible, since it does not give you the ability to have multiple frames
|
|
|
2430 with different WM_CLASS properties. Another possibility would be for
|
|
|
2431 the default frame name to come from the application name instead of
|
|
|
2432 simply being @samp{emacs}. However, at this point, making that change
|
|
|
2433 would be troublesome: it would mean that many users would have to make
|
|
|
2434 yet another change to their resource files (since the default frame name
|
|
|
2435 would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
|
|
|
2436 the executable happened to be named), so we'd rather avoid it.
|
|
|
2437
|
|
|

|
|
|
2439
|
|

2531 @section How can I limit color map usage?
|
|
|
2532
|
|
|
2533 I'm using Netscape (or another color grabber like XEmacs);
|
|
|
2534 is there anyway to limit the number of available colors in the color map?
|
|
|
2535
|
|
126
|
2536 XEmacs 19.13 didn't have such a mechanism (unlike netscape, or other
|
|
82
|
2537 color-hogs). One solution is to start XEmacs prior to netscape, since
|
|
|
2538 this will prevent Netscape from grabbing all colors (but Netscape will
|
|
|
2539 complain). You can use the flags for Netscape, like -mono, -ncols <#>
|
|
|
2540 or -install (for mono, limiting to <#> colors, or for using a private
|
|
|
2541 color map). Since Netscape will take the entire colormap and never
|
|
|
2542 release it, the only reasonable way to run it is with @samp{-install}.
|
|
|
2543
|
|
|
2544 If you have the money, another solution would be to use a truecolor or
|
|
|
2545 direct color video.
|
|
|
2546
|
|
|
2547 Starting with XEmacs 19.14, XEmacs uses the closest available color if
|
|
|
2548 the colormap is full, so it's O.K. now to start Netscape first.

|

2632

2633 You can use something like the following:

2634
|
|
|
2635 @lisp
|
|
|
2636 (add-hook 'lisp-mode-hook

|
|
82
|
2639 @end lisp
|
|
|
2640
|
|
|
2641 Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline
|
|
|
2642 colors change from the default set in your @file{.emacs}. The change
|
|
|
2643 will only be made in the buffer you just entered (which contains the
|
|
|
2644 Lisp file you are editing) and will not affect the modeline colors
|
|
|
2645 anywhere else.
|
|
|

2653 c++-mode-hook, emacs-lisp-mode-hook (used for your @file{.emacs} or a
|
|
|
2654 @file{xx.el} file), lisp-interaction-mode-hook (the @samp{*scratch*}

|
2660 hook.
|

|
|
|
2695 As an example, say you want the @kbd{paste} key on a Sun keyboard to
|
|
|
2696 insert the current Primary X selection at point. You can accomplish this
|
|
|
2697 with:
|
|
|
2698
|
|
|
2699 @lisp
|
|
|
2700 (define-key global-map [f18] 'x-insert-selection)
|
|
|
2701 @end lisp
|
|
|
2702
|
|
|
2703 However, this only works if there is a current X selection (the
|
|
|
2704 selection will be highlighted). The functionality I like is for the
|
|
|
2705 @kbd{paste} key to insert the current X selection if there is one,
|
|
|
2706 otherwise insert the contents of the clipboard. To do this you need to
|
|
|
2707 pass arguments to @code{x-insert-selection}. This is done by wrapping
|
|
|
2708 the call in a 'lambda form:
|
|
|
2709
|
|
|
2710 @lisp
|
|
163
|
2711 (global-set-key [f18]
|
|
|
2712 (lambda () (interactive) (x-insert-selection t nil)))
|
|
82
|
2713 @end lisp
|
|
|
2714
|
|
|
2715 This binds the f18 key to a @dfn{generic} functional object. The
|
|
|
2716 interactive spec is required because only interactive functions can be
|
|
163
|
2717 bound to keys.
|
|
82
|
2718
|
|
|
2719 For the FAQ example you could use:
|
|
|
2720
|
|
|
2721 @lisp
|
|
|
2722 (global-set-key [(control ?.)]
|

2723 (lambda () (interactive) (scroll-up 1)))

|
82

2725 (lambda () (interactive) (scroll-up -1)))
|
|
82
|
2726 @end lisp
|
|
|
2727
|
|
|
2728 This is fine if you only need a few functions within the lambda body.

2834 But it doesn't work alone. This is in the file @file{PROBLEMS} which
|

2835 should have come with your XEmacs installation: @emph{Emacs ignores the

2836 @kbd{help} key when running OLWM}.
|
|
|
2837
|
|
|
2838 OLWM grabs the @kbd{help} key, and retransmits it to the appropriate
|
|
|
2839 client using @code{XSendEvent}. Allowing Emacs to react to synthetic
|
|
|
2840 events is a security hole, so this is turned off by default. You can
|
|
|
2841 enable it by setting the variable @code{x-allow-sendevents} to t. You
|
|
|
2842 can also cause fix this by telling OLWM to not grab the help key, with
|
|
|
2843 the null binding @code{OpenWindows.KeyboardCommand.Help:}.

3149 There are redisplay bugs in 19.14 that may make the preceding result in

|
|
3150 a messed-up display, especially for frames with multiple windows. You

3151 may need to resize the frame before XEmacs completely realizes the

3158 @section How can I disable the scrollbar?
|
|
|
3159
|
|
|
3160 To disable them for all frames, add the following line to
|
|
|
3161 your @file{.Xdefaults}:
|
|
|
3162
|
|
|
3163 @example
|
|
|
3164 Emacs.scrollBarWidth: 0
|
|
|
3165 @end example
|
|
|
3166
|
|
|
3167 To turn the scrollbar off on a per-frame basis, use the following
|
|
|
3168 function:
|
|
|
3169
|
|
|
3170 @lisp
|
|
163
|
3171 (set-specifier scrollbar-width 0 (selected-frame))
|
|
82
|
3172 @end lisp
|
|
|
3173
|
|
|
3174 You can actually turn the scrollbars on at any level you want by
|
|
|
3175 substituting for (selected-frame) in the above command. For example, to
|
|
|
3176 turn the scrollbars off only in a single buffer:
|
|
|
3177
|
|
|
3178 @lisp
|
|
163
|
3179 (set-specifier scrollbar-width 0 (current-buffer))
|
|
82
|
3180 @end lisp
|
|
|
3181
|
|
163
|
3182 In XEmacs versions prior to 19.14, you had to use the hairier construct:
|
|
82
|
3183
|
|
|
3184 @lisp
|

163
|
3185 (set-specifier scrollbar-width (cons (selected-frame) 0))

3191 Here's a recap of how to use resources to change your scrollbar colors:
|
|
|
3192
|
|
|
3193 @example
|
|
|
3194 ! Motif scrollbars
|
|
|
3195
|
|

3196 Emacs*XmScrollBar.Background: skyblue
|

|

3198
|
|
|
3199 ! Athena scrollbars
|
|
|
3200
|
|
|
3201 Emacs*Scrollbar.Foreground: skyblue
|
|
|
3202 Emacs*Scrollbar.Background: lightgray
|
|
|
3203 @end example
|
|

|
|
|
3209
|
|
|
3210 When I move the scrollbar in an XEmacs window, it moves the point as
|
|
|
3211 well, which should not be the default behavior. Is this a bug or a
|
|
|
3212 feature? Can I disable it?
|
|
|
3213
|
|
|
3214 The current behavior is a feature, not a bug. Point remains at the same
|
|
|
3215 buffer position as long as that position does not scroll off the screen.
|
|
|
3216 In that event, point will end up in either the upper-left or lower-left
|
|
|
3217 hand corner.
|
|
|
3218
|
|
|
3219 This cannot be changed.

|
|
|
3223
|
|
|
3224 By the same token, how can I turn it off in specific modes?
|
|
|
3225
|
|
|
3226 To do this, add to your @file{.emacs} file:
|
|
|
3227
|
|
|
3228 @lisp
|
|
|
3229 (require 'auto-show)
|
|
|
3230 @end lisp
|
|
|
3231
|
|
|
3232 Then do @code{(setq truncate-lines t)} in the mode-hooks for any modes
|
|
|
3233 in which you want lines truncated.
|
|
|
3234
|
|
|
3235 More precisely: If @code{truncate-lines} is nil, horizontal scrollbars
|
|
|
3236 will never appear. Otherwise, they will appear only if the value of
|
|
|
3237 @code{scrollbar-height} for that buffer/window/etc. is non-zero. If you
|
|
|
3238 do
|
|
|
3239
|
|
|
3240 @lisp
|
|
|
3241 (set-specifier scrollbar-height 0)
|
|
|
3242 @end lisp
|
|
|
3243
|
|
|
3244 then horizontal scrollbars will not appear in truncated buffers unless
|
|
|
3245 the package specifically asked for them.
|
|
|
3246
|
|
|
3247 Automatic horizontal scrolling is now standard, starting with 19.14.

|
|

3251
|
|
|
3252 The @code{zmacs} mode allows for what some might call gratuitous
|
|
|
3253 highlighting for selected regions (either by setting mark or by using
|
|
|
3254 the mouse). This is the default behavior. To turn off, add the
|
|
|
3255 following line to your @file{.emacs} file:
|
|
|
3256
|
|
|
3257 @lisp

|

3267 I want to change things so that if I select some text and start typing,
|
|
|
3268 the typed text replaces the selected text, similar to Motif.
|
|
|
3269
|
|
|
3270 You want to use something called @dfn{pending delete}. Pending delete
|
|
|
3271 is what happens when you select a region (with the mouse or keyboard)
|
|
|
3272 and you press a key to replace the selected region by the key you typed.
|
|
|
3273 Usually backspace kills the selected region.
|

3274

3297 solution consists of customizing the @code{isearch} face.

3470 home... Is there a recommended setup?

3509 @code{/bin/mail} using the protocol defined by @code{/bin/mail}.
|
|
|
3510
|
|
|
3511 There are two different protocols in general use. One of them uses the
|
|
|
3512 @code{flock} system call. The other involves creating a lock file;
|
|
|
3513 @code{movemail} must be able to write in @file{/usr/spool/mail} in order
|
|
|
3514 to do this. You control which one is used by defining, or not defining,
|
|
|
3515 the macro @code{MAIL_USE_FLOCK} in @file{config.h} or the m- or s- file
|
|
|
3516 it includes.

3525 root):

3527 @example
|

3543 Installation normally copies movemail from the build directory to an
|

3544 installation directory which is usually under @file{/usr/local/lib}.
|
|
|
3545 The installed copy of @code{movemail} is usually in the directory
|
|
|
3546 @file{/usr/local/lib/emacs/VERSION/TARGET}. You must change the group
|
|
|
3547 and mode of the installed copy; changing the group and mode of the build

3548 directory copy is ineffective.

3701 mailcrypt. It provides totally transparent and trouble-free MIME

3841 InfoDock is an integrated productivity toolset, mainly aimed at
|
|
86
|
3842 technical people. It is developed and supported by InfoDock
|
|
|
3843 Associates, a firm that offers custom support and development
|
|
|
3844 for InfoDock, XEmacs and GNU Emacs. (http://www.infodock.com,
|
|
88
|
3845 <info@@infodock.com>, +1 408 243 3300).
|
|
86
|
3846
|
|
|
3847 InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
|
|
|
3848 the power of Emacs, but with an easier to use and more comprehensive
|
|
|
3849 menu-based user interface. The bottom portion of this text describes
|
|
|
3850 how it differs from XEmacs and GNU Emacs from the Free Software
|

3851 Foundation.

3853 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
3854 environment. Although InfoDock is customizable, it is not intended for
|
|
|
3855 people who like basic versions of Emacs which need to be customized
|
|
|
3856 extensively for local use; standard Emacs distributions are better for
|
|
|
3857 such uses. InfoDock is for those people who want a complete,
|
|
|
3858 pre-customized environment in one package, which they need not touch
|
|
|
3859 more than once or twice a year to update to new revisions.
|
|
|
3860
|
|
86
|
3861 InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
|
|
|
3862 and Intel Linux systems. It is intended for use on a color display,
|
|
|
3863 although most features will work on monochrome monitors. Simply unpack
|
|
|
3864 InfoDock according to the instructions in the ID-INSTALL file and you
|
|
|
3865 are ready to run.

3867 The InfoDock Manual is concise, yet sufficient as a user guide for users

3868 who have never used an Emacs-type editor before. For users who are

|

4065 The reason for an Emacs package not to be included in XEmacs is

4066 usually one or more of the following:

|
4067
|
|

4068 @enumerate

|
4070 The package has not been ported to XEmacs. This will typically happen
|
|
|
4071 when it uses GNU-Emacs-specific features, which make it fail under
|
|
|
4072 XEmacs.
|
|
|
4073
|
|
|
4074 Porting a package to XEmacs can range from a trivial amount of change to
|
|
|
4075 a partial or full rewrite. Fortunately, the authors of modern packages
|
|
|
4076 usually choose to support both Emacsen themselves.
|
|
|
4077
|
|
|
4078 @item
|
|
|
4079 The package has been decided not to be appropriate for XEmacs. It may
|
|
|
4080 have an equivalent or better replacement within XEmacs, in which case
|
|
|
4081 the developers may choose not to burden themselves with supporting an
|
|
|
4082 additional package.
|
|
|
4083
|
|
|
4084 Each package bundled with XEmacs means more work for the maintainers,
|
|
|
4085 whether they want it or not. If you are ready to take over the
|
|
|
4086 maintainence responsibilities for the package you port, be sure to say
|

4087 so -- we will more likely include it.

4164
|
|

4165 For most modes, font-lock is already set up and just needs to be turned
|
|
|
4166 on. This can be done by @kbd{M-x font-lock-mode}, or by having XEmacs

|
|
|
4179
|
|
|
4180 Well, first off, consider if you really want to do this. cc-mode is
|
|
|
4181 much more powerful than the old c-mode. If you're having trouble
|
|
|
4182 getting your old offsets to work, try using @code{c-set-offset} instead.
|
|
|
4183 You might also consider using the package @code{cc-compat}.
|
|
|
4184
|
|
|
4185 But, if you still insist, add the following lines to your @file{.emacs}:
|
|
|
4186

4187 @lisp

4188 (fmakunbound 'c-mode)

4210 like this:

4254 @strong{WARNING}: note that changing the value of
|
|
|
4255 @code{default-major-mode} from @code{fundamental-mode} can break a large
|
|
|
4256 amount of built-in code that expects newly created buffers to be in
|
|
|
4257 @code{fundamental-mode}. (Changing from @code{fundamental-mode} to
|
|
|
4258 @code{text-mode} might not wreak too much havoc, but changing to
|
|
|
4259 something more exotic like a lisp-mode would break many Emacs packages).
|
|
|
4260
|
|
|
4261 Note that Emacs by default starts up in buffer @code{*scratch*} in
|
|
|
4262 @code{initial-major-mode}, which defaults to
|
|
|
4263 @code{lisp-interaction-mode}. Thus adding the following form to your
|
|
|
4264 Emacs init file will cause the initial @code{*scratch*} buffer to be put
|
|
|
4265 into auto-fill'ed @code{text-mode}:
|
|
|
4266
|
|
|
4267 @lisp
|

|
4268 (setq initial-major-mode

4272 @end lisp
|
|
|
4273
|
|
|
4274 Note that after your init file is loaded, if
|
|
163
|
4275 @code{inhibit-startup-message} is @code{nil} (the default) and the
|
|
|
4276 startup buffer is @code{*scratch*} then the startup message will be
|
|
|
4277 inserted into @code{*scratch*}; it will be removed after a timeout by
|
|
|
4278 erasing the entire @code{*scratch*} buffer. Keep in mind this default
|
|
|
4279 usage of @code{*scratch*} if you desire any prior manipulation of
|
|
82
|
4280 @code{*scratch*} from within your Emacs init file. In particular,
|
|
|
4281 anything you insert into @code{*scratch*} from your init file will be
|
|
|
4282 later erased. Also, if you change the mode of the @code{*scratch*}
|
|
|
4283 buffer, be sure that this will not interfere with possible later
|
|
|
4284 insertion of the startup message (e.g. if you put @code{*scratch*} into
|
|
|
4285 a nonstandard mode that has automatic font lock rules, then the startup
|
|
|
4286 message might get fontified in a strange foreign manner, e.g. as code in
|
|
|
4287 some programming language).

4486 Emacs has a legacy of keyboards that produced characters with modifier
|
|
|
4487 bits, and therefore map a variety of input systems into this scheme even
|
|
|
4488 today. XEmacs is instead optimized for X events. This causes an
|
|
|
4489 incompatibility in the way key sequences are specified, but both Emacs
|
|
|
4490 and XEmacs will accept a key sequence as a vector of lists of modifiers
|
|
163
|
4491 that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
|
|
|
4492 @code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
|
|
|
4493 form for a single key, just (meta control a). Emacs has an abbreviated
|
|
|
4494 form for the Control and the Meta modifiers to string-characters (the
|
|
|
4495 ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
|
|
|
4496 that the abbreviated form works only for one-character key sequences,
|
|
|
4497 while Emacs users need to be aware that the string-character is rather
|
|
|
4498 limited. Specifically, the string-character can accomodate only 256
|
|
|
4499 different values, 128 of which have the Meta modifier and 128 of which
|
|
|
4500 have not. In each of these blocks, only 32 characters have the Control
|
|
|
4501 modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
|
|
|
4502 control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
|
|
|
4503 do not. Programmers are advised to use the full common form, both
|
|
|
4504 because it is more readable and less error-prone, and because it is
|
|
|
4505 supported by both Emacsen.

4575 @kbd{RET} are synonymous.) You can use angle brackets on the words

4586 precede a character or key notation. For function keys, the prefixes
|
|
|
4587 may go inside or outside of the brackets: @code{C-<down>} @equiv{}

4638 value, and use @code{setq} to set it later.
|
|
|
4639
|
|
|
4640 It is never a good practice to @code{setq} user variables (like

4641 @code{case-fold-search}, etc.), as it ignores the user's choice
|

4660 you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
|

4661 can even return one of its local variables.
|

4695 @section What is the typical misuse of @code{setq} ?
|
|
|
4696
|
|
|
4697 A typical misuse is probably @code{setq}ing a variable that was meant to
|
|
|
4698 be local. Such a variable will remain bound forever, never to be
|
|
|
4699 garbage-collected. For example, the code doing:
|
|
|
4700
|
|
|
4701 @lisp
|
|
|
4702 (defun my-function (whatever)
|
|
|
4703 (setq a nil)
|
|
|
4704 ... build a large list ...
|
|
|
4705 ... and exit ...)
|
|
|
4706 @end lisp
|
|
|
4707
|
|
|
4708 does a bad thing, as @code{a} will keep consuming memory, never to be
|
|
|
4709 unbound. The correct thing is to do it like this:
|
|
|
4710
|
|
|
4711 @lisp
|
|
|
4712 (defun my-function (whatever)
|
|
|
4713 (let (a) ; default initialization is to nil
|
|
|
4714 ... build a large list ...
|
|
|
4715 ... and exit, unbinding `a' in the process ...)
|
|
|
4716 @end lisp
|
|
|
4717
|
|
|
4718 Not only is this prettier syntactically, but it makes it possible for
|
|
|
4719 Emacs to garbage-collect the objects which @code{a} used to reference.
|
|
|
4720
|
|
|
4721 Note that even global variables should not be @code{setq}ed without
|
|
|
4722 @code{defvar}ing them first, because the byte-compiler issues warnings.
|
|
|
4723 The reason for the warning is the following:
|
|
|
4724
|
|
|
4725 @lisp
|
|
|
4726 (defun flurgoze nil) ; ok, global internal variable
|
|
|
4727 ...
|
|
|
4728
|
|
|
4729 (setq flurghoze t) ; ops! a typo, but semantically correct.
|
|
|
4730 ; however, the byte-compiler warns.
|
|
|
4731
|
|
|

|
4743 Many of the advanced features of this package, such as @code{defun*},
|
|
|
4744 @code{loop}, and @code{setf}, are implemented as Lisp macros. In
|
|
|
4745 byte-compiled code, these complex notations will be expanded into
|
|
|
4746 equivalent Lisp code which is simple and efficient. For example, the
|
|
|
4747 forms
|
|
82
|
4748
|
|
|
4749 @lisp
|
|
163
|
4750 (incf i n)
|
|
|
4751 (push x (car p))
|
|
82
|
4752 @end lisp
|
|
|
4753
|

|
4754 are expanded at compile-time to the Lisp forms
|
|
82

4755
|

4756 @lisp
|

4757 (setq i (+ i n))

|

82
|
4759 @end lisp
|
|
|
4760
|
|
163
|
4761 which are the most efficient ways of doing these respective operations
|
|
|
4762 in Lisp. Thus, there is no performance penalty for using the more
|
|
|
4763 readable @code{incf} and @code{push} forms in your compiled code.
|
|
|
4764
|
|
|
4765 @emph{Interpreted} code, on the other hand, must expand these macros
|
|
|
4766 every time they are executed. For this reason it is strongly
|
|
|
4767 recommended that code making heavy use of macros be compiled. (The
|
|
|
4768 features labelled @dfn{Special Form} instead of @dfn{Function} in this
|
|
|
4769 manual are macros.) A loop using @code{incf} a hundred times will
|
|
|
4770 execute considerably faster if compiled, and will also garbage-collect
|
|
|
4771 less because the macro expansion will not have to be generated, used,
|
|
|
4772 and thrown away a hundred times.
|
|
|
4773
|
|
|
4774 You can find out how a macro expands by using the @code{cl-prettyexpand}
|
|
|
4775 function.

4781 Yes. Emacs byte-compiler cannot do much to optimize recursion. But
|
|
|
4782 think well whether this is a real concern in Emacs. Much of the Emacs
|

4783 slowness comes from internal mechanisms such as redisplay, or from the

|
4804 the image (e.g. @code{xpm}, @code{xbm}, @code{gif}, @code{jpeg}, etc.)
|
|
|
4805 Instead of @samp{FILE}, use the image file name
|

4806 (e.g. @file{/usr/local/lib/xemacs-20.2/etc/recycle.xpm}).
|
|
|
4807
|

4808 You can turn this to a function (that optionally prompts you for a file

4863 @section How do you make XEmacs indent CL if-clauses correctly?
|
|
|
4864
|
|
|
4865 I'd like XEmacs to indent all the clauses of a Common Lisp @code{if} the
|
|
|
4866 same amount instead of indenting the 3rd clause differently from the
|
|
|
4867 first two.
|
|
70
|
4868
|
|
|
4869 One way is to add, to @file{.emacs}:
|
|
|
4870
|
|
82
|
4871 @lisp
|
|
70
|
4872 (put 'if 'lisp-indent-function nil)
|
|
82
|
4873 @end lisp
|
|
70
|
4874
|
|
|
4875 However, note that the package @file{cl-indent.el} that comes with
|
|
82
|
4876 XEmacs sets up this kind of indentation by default. @code{cl-indent}
|
|
|
4877 also knows about many other CL-specific forms. To use @code{cl-indent},
|
|
|
4878 one can do this:
|
|
|
4879
|
|
|
4880 @lisp
|
|
70
|
4881 (load "cl-indent")
|

4882 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
82
|
4883 @end lisp
|
|
|
4884
|
|
|
4885 One can also customize @file{cl-indent.el} so it mimics the default
|
|
|
4886 @code{if} indentation @code{then} indented more than the @code{else}.
|
|
|
4887 Here's how:
|
|
|
4888
|
|
|
4889 @lisp
|
|
70
|
4890 (put 'if 'common-lisp-indent-function '(nil nil &body))
|
|
82
|
4891 @end lisp
|
|
70
|
4892
|
|
|
4893 Also, a new version (1.2) of @file{cl-indent.el} was posted to
|
|
82
|
4894 comp.emacs.xemacs on 12/9/94. This version includes more documentation
|

4895 than previous versions. This may prove useful if you need to customize

4896 any indent-functions.

5044 Yes, abbrevs only expands word-syntax strings. While XEmacs does not
|
|
|
5045 prevent you from defining (e.g. with @kbd{C-x a g} or @kbd{C-x a l})
|
|
|
5046 abbrevs that contain special characters, it will refuse to expand
|
|
|
5047 them. So you need to ensure, that the abbreviation contains letters and
|
|
|
5048 digits only. This means that @samp{xd}, @samp{d5}, and @samp{5d} are
|
|
|
5049 valid abbrevs, but @samp{&d}, and @samp{x d} are not.
|
|
|
5050
|
|
|
5051 If this sounds confusing to you, (re-)read the online documentation for
|
|
|
5052 abbrevs (@kbd{C-h i m XEmacs RET m Abbrevs RET}), and then come back and
|
|
|
5053 read this question/answer again.

5057 which is currently in beta. Hrvoje Niksic <hniksic@@srce.hr> will

5058 appreciate it if you download a beta, try out whether abbreviations work

5062 @section How can I get those oh-so-neat X-Face lines?
|
|
|
5063
|
|
|
5064 Firstly there is an ftp site which describes X-faces and has the
|
|
|
5065 associated tools mentioned below, at
|
|
|
5066 <URL:ftp://ftp.cs.indiana.edu:/pub/faces/>.
|
|
|
5067
|
|
|
5068 Then the steps are
|
|
|
5069
|
|
|
5070 @enumerate
|
|
|
5071 @item
|
|
|
5072 Create 48x48x1 bitmap with your favorite tool
|
|
|
5073
|
|
|
5074 @item
|
|
|
5075 Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
|
|
|
5076 and then compile the face.
|
|
|
5077
|
|
|
5078 @item
|
|
0
|
5079 @example
|
|
82
|
5080 cat file.xbm | xbm2ikon |compface > file.face
|
|
0
|
5081 @end example
|
|
|
5082
|
|
82
|
5083 @item
|
|
|
5084 Then be sure to quote things that are necessary for emacs strings:
|
|
0
|
5085
|
|
|
5086 @example
|
|
82
|
5087 cat ./file.face | sed 's/\\/\\\\/g' | sed 's/\"/\\\"/g' > ./file.face.quoted
|
|
0
|
5088 @end example
|
|
|
5089
|
|
82
|
5090 @item
|
|
|
5091 Then set up emacs to include the file as a mail header - there were a
|
|
|
5092 couple of suggestions here---either something like:
|
|
|
5093
|
|
|
5094 @lisp
|
|
|
5095 (setq mail-default-headers
|
|
|
5096 "X-Face: <Ugly looking text string here>")
|
|
|
5097 @end lisp
|
|
|
5098
|
|
|
5099 Or, alternatively, as:
|
|
|
5100
|
|
|
5101 @lisp
|
|
|
5102 (defun mail-insert-x-face ()
|
|
|
5103 (save-excursion
|
|
|
5104 (goto-char (point-min))
|
|
|
5105 (search-forward mail-header-separator)
|
|
163
|
5106 (beginning-of-line)
|
|
82
|
5107 (insert "X-Face:")
|
|
163
|
5108 (insert-file-contents "~/.face")))
|
|
82
|
5109
|
|
|
5110 (add-hook 'mail-setup-hook 'mail-insert-x-face)
|
|
|
5111 @end lisp
|
|
|
5112 @end enumerate
|
|
|
5113
|
|
|
5114 However, 2 things might be wrong:
|
|
|
5115
|
|
|
5116 Some versions of pbmtoicon produces some header lines that is not
|
|
|
5117 expected by the version of compface that I grabbed. So I found I had to
|
|
|
5118 include a @code{tail +3} in the pipeline like this:
|
|
0
|
5119
|
|
|
5120 @example
|
|
82
|
5121 cat file.xbm | xbm2ikon | tail +3 |compface > file.face
|
|
0
|
5122 @end example
|
|
|
5123
|
|
82
|
5124 Some people have also found that if one uses the @code{(insert-file)}
|
|
|
5125 method, one should NOT quote the face string using the sed script .
|
|
|
5126
|
|
|
5127 It might also be helpful to use Stig's <stig@@hackvan.com> script
|
|
|
5128 (included in the compface distribution at XEmacs.org) to do the
|
|
|
5129 conversion. For convenience xbm2xface is available for anonymous FTP at
|
|
|
5130 <URL:ftp://ftp.miranova.com/pub/xemacs/xbm2xface.pl>.

5157 Emacs Info and XEmacs Info do many things differently. If you're trying to

5162 Emacs Info scans @code{Info-directory-list} from right-to-left while
|
|
|
5163 XEmacs Info reads it from left-to-right, so append to the @emph{correct}
|
|
|
5164 end of the list.
|
|
|
5165
|
|
|
5166 @item
|
|
|
5167 Use @code{Info-default-directory-list} to initialize
|
|
|
5168 @code{Info-directory-list} @emph{if} it is available at startup, but not
|
|
|
5169 all Emacsen define it.
|
|
|
5170
|
|
|
5171 @item
|
|
|
5172 Emacs Info looks for a standard @file{dir} file in each of the
|
|
|
5173 directories scanned from #1 and magically concatenates them together.
|
|
|
5174
|
|
|
5175 @item
|
|
|
5176 XEmacs Info looks for a @file{localdir} file (which consists of just the
|
|
|
5177 menu entries from a @file{dir} file) in each of the directories scanned
|
|
|
5178 from #1 (except the first), does a simple concatentation of them, and
|
|
|
5179 magically attaches the resulting list to the end of the menu in the
|
|
|
5180 @file{dir} file in the first directory.
|
|
|
5181 @end enumerate
|
|
|
5182
|
|
|
5183 Another alternative is to convert the documentation to HTML with
|
|
|
5184 texi2html and read it from a web browser like Lynx or W3.

5188 @section What do I need to change to make printing work?
|
|
|
5189
|
|
|
5190 For regular printing there are two variables that can be customized.
|
|
|
5191
|
|
|
5192 @table @code
|
|
|
5193 @item lpr-command
|
|
|
5194 This should be set to a command that takes standard input and sends
|
|
|
5195 it to a printer. Something like:
|
|
|
5196
|
|
|
5197 @lisp
|
|
|
5198 (setq lpr-command "lp")
|
|
|
5199 @end lisp
|
|
|
5200
|
|
|
5201 @item lpr-switches
|
|
|
5202 This should be set to a list that contains whatever the print command
|
|
|
5203 requires to do its job. Something like:
|
|
|
5204
|
|
|
5205 @lisp
|
|
|
5206 (setq lpr-switches '("-depson"))
|
|
|
5207 @end lisp
|
|
|
5208 @end table
|
|
|
5209
|
|
|
5210 For postscript printing there are three analogous variables to
|
|
|
5211 customize.
|
|
|
5212
|
|
|
5213 @table @code
|
|
|
5214 @item ps-lpr-command
|
|
|
5215 This should be set to a command that takes postscript on standard input
|
|
|
5216 and directs it to a postscript printer.
|
|
|
5217
|
|
|
5218 @item ps-lpr-switches
|
|
|
5219 This should be set to a list of switches required for
|
|
|
5220 @code{ps-lpr-command} to do its job.
|
|
|
5221
|
|
|
5222 @item ps-print-color-p
|
|
|
5223 This boolean variable should be set @code{t} if printing will be done in
|
|
|
5224 color, otherwise it should be set to @code{nil}.
|
|
|
5225 @end table
|
|
|
5226
|
|
|
5227 NOTE: It is an undocumented limitation in XEmacs that postscript
|
|
|
5228 printing (the @code{Pretty Print Buffer} menu item) @strong{requires} a
|
|
|
5229 window system environment. It cannot be used outside of X11.

5249 The biggest changes in 20.2 include intergration of EFS (the next

|
5250 generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
|
|
126
|
5251 major mode for editing Tex and LaTeX, and a lot of other stuff). Many
|
|
163
|
5252 bugs from 20.0 have been fixed for this release. 20.2 also contains a
|
|
|
5253 new system for customizing XEmacs options, invoked via @kbd{M-x
|
|
|
5254 customize}.
|
|
|
5255
|
|
|
5256 XEmacs 20.2 is the development release (20.0 was beta), and is no longer

|
|

5262 XEmacs release 20.3 is planned for autumn 1997. It will likely contain
|
|
|
5263 a much smaller amount of code for basic functionality, with all the
|
|
|
5264 popular Lisp packages being available in the form of easy-to-install
|
|
|
5265 add-ons.
|
|
|
5266
|
|
|
5267 Other input methods (such as skk) will be made available for Mule, as
|
|
|
5268 well as more user-level documentation.
|
|
|
5269
|
|
|
5270 Many new features are planned, such as multiple TTY frames, support for
|
|

5271 Autoconf 2, synches with Emacs 20.1, and more; much of this is already
|
|
|
5272 running in various beta versions. Ask at
