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.

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

163
|
506 support. XEmacs 20.0 was released in February 1997, followed by XEmacs
|
|
|
507 20.2 in May. When compiled without MULE support 20.2 is currently very
|
|
|
508 similar to 19.15 (except for some changes to the byte-code format, some
|
|
|
509 new primitive types including @code{char}, @code{char-table}, and
|
|
|
510 @code{range-table}) and equally stable.

532 it. However, menubar localization @emph{does} work, even in 19.14. To

535 @example

536 Emacs*XlwMenu.resourceLabels: True

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

574 Egg consists of following parts:

|

575
|
|
|
576 @enumerate
|
|
|
577 @item Input character Translation System (ITS) layer.
|
|
|
578 It translates ASCII inputs to Kana/PinYin/Hangul characters.
|
|
|
579
|
|
|
580 @item Kana/PinYin/Hangul to Kanji transfer layer.
|
|
126
|
581 It is interface layer for network Kana-Kanji server (Wnn and Sj3).
|
|
82
|
582 @end enumerate
|
|
|
583
|
|
|
584 These input methods are modal, namely there are mode, alphabet mode and
|
|
|
585 Kana-Kanji transfer mode. However there are mode-less input methods for
|
|
|
586 Egg and Canna. @samp{Boiled-egg} is a mode-less input method running on
|
|
|
587 Egg. For Canna, @samp{canna.el} has a tiny boiled-egg like command,
|
|
|
588 @code{(canna-boil)}, and there are some boiled-egg like utilities. In
|
|
|
589 addition, it was planned to make an abstraction for all transfer type
|
|
|
590 input methods. However authors of input methods are busy, so maybe this
|
|
|
591 plan is stopped. Perhaps after Mule merged GNU Emacs will be released,
|
|

592 it will be continued.

601 MULE and XEmacs are quite different. So the application

602 implementor must write separate code for these mule variants.
|

603
|

604 MULE and the next version of Emacs are similar but the symbols are very

667
|
|

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

701 @section May I see an example of a useful XEmacs Lisp function?
|
|
|
702
|
|
|
703 The following function does a little bit of everything useful. It does
|
|
|
704 something with the prefix argument, it examines the text around the
|
|
|
705 cursor, and it's interactive so it may be bound to a key. It inserts
|
|
|
706 copies of the current word the cursor is sitting on at the cursor. If
|
|
|
707 you give it a prefix argument: @kbd{C-u 3 M-x double-word} then it will
|
|
|
708 insert 3 copies.
|
|
|
709
|
|
|
710 @lisp
|
|
|
711 (defun double-word (count)
|
|
|
712 "Insert a copy of the current word underneath the cursor"
|
|
|
713 (interactive "*p")
|
|
|
714 (let (here there string)
|
|
|
715 (save-excursion
|
|
|
716 (forward-word -1)
|
|
|
717 (setq here (point))
|
|
|
718 (forward-word 1)
|
|
|
719 (setq there (point))
|
|
|
720 (setq string (buffer-substring here there)))
|
|
|
721 (while (>= count 1)
|
|
163
|
722 (insert string)
|
|
|
723 (decf count))))
|
|
82
|
724 @end lisp
|
|
|
725
|
|
|
726 The best way to see what is going on here is to let XEmacs tell you.
|
|
|
727 Put the code into an XEmacs buffer, and do a @kbd{C-h f} with the cursor
|
|
|
728 sitting just to the right of the function you want explained. Eg. move
|
|
|
729 the cursor to the SPACE between @code{interactive} and @samp{"*p"} and
|
|
|
730 hit @kbd{C-h f} to see what the function @code{interactive} does. Doing
|
|
|
731 this will tell you that the @code{*} requires a writable buffer, and
|
|
|
732 @code{p} converts the prefix argument to a number, and
|
|
|
733 @code{interactive} allows you to execute the command with @kbd{M-x}.

|

738 To bind to a key do:
|
|
|
739
|
|
|
740 @lisp
|
|
|
741 (global-set-key "\C-cd" 'double-word)
|
|
|
742 @end lisp
|
|

743
|

744 Or interactively, @kbd{M-x global-set-key} and follow the prompts.

753 @section What's the difference between a macro and a function?
|
|
|
754
|
|
163
|
755 Quoting from the Lisp Reference (a.k.a @dfn{Lispref}) Manual:
|
|
82
|
756
|
|
|
757 @dfn{Macros} enable you to define new control constructs and other
|
|
|
758 language features. A macro is defined much like a function, but instead
|
|
|
759 of telling how to compute a value, it tells how to compute another Lisp
|
|
|
760 expression which will in turn compute the value. We call this
|
|
|
761 expression the @dfn{expansion} of the macro.
|
|
|
762
|
|
|
763 Macros can do this because they operate on the unevaluated expressions
|
|
|
764 for the arguments, not on the argument values as functions do. They can
|
|
|
765 therefore construct an expansion containing these argument expressions
|
|
|
766 or parts of them.
|
|
|
767
|
|
163
|
768 Do not confuse the two terms with @dfn{keyboard macros}, which are
|
|
|
769 another matter, entirely. A keyboard macro is a key bound to several
|
|
|
770 other keys. Refer to manual for details.

780 @end lisp

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

126
|
783 delete these options. XEmacs 19.14 and later no longer write the
|
|
|
784 options directly to @file{.emacs} which should allow us to deal with
|
|
|
785 version incompatibilities better in the future.
|
|
82
|
786
|
|
|
787 Options saved under XEmacs 19.13 are protected by code that specifically

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

789 testing XEmacs v20. You should consider changing the code to read:

|
|
790
|
|
|

792 (cond

793 ((and (string-match "XEmacs" emacs-version)

853
|
|
|
854 The @file{INSTALL} file says that up to 108 MB of space is needed
|
|
|
855 temporarily during installation! How can I just try it out?
|
|
|
856
|
|
|
857 XEmacs will run in place without requiring installation and copying of
|
|
|
858 the Lisp directories, and without having to specify a special build-time
|
|
|
859 flag. It's the copying of the Lisp directories that requires so much
|
|
|
860 space. XEmacs is largely written in Lisp.
|
|
|
861
|
|
|
862 A good method is to make a shell alias for xemacs:
|
|
|
863
|
|
|
864 @example
|
|
163
|
865 alias xemacs=/i/xemacs-20.2/src/xemacs
|
|
82
|
866 @end example
|
|
|
867
|
|
|
868 (You will obviously use whatever directory you downloaded the source
|
|
163
|
869 tree to instead of @file{/i/xemacs-20.2}).
|
|
82
|
870
|
|
|
871 This will let you run XEmacs without massive copying.

884 @section Compiling XEmacs with Netaudio.
|
|
|
885
|
|
|
886 What is the best way to compile XEmacs with the netaudio system, since I
|
|
|
887 have got the netaudio system compiled but installed at a weird place, I
|
|
|
888 am not root. Also in the READMEs it does not say anything about
|
|
|
889 compiling with the audioserver?
|
|
|
890
|
|
|
891 You should only need to add some stuff to the configure command line.
|
|
|
892 To tell it to compile in netaudio support: @samp{--with-sound=both}, or
|
|
|
893 @samp{--with-sound=nas} if you don't want native sound support for some
|
|
|
894 reason.) To tell it where to find the netaudio includes and libraries:
|
|
16
|
895
|
|
|
896 @example
|
|
82
|
897 --site-libraries=WHATEVER
|
|
|
898 --site-includes=WHATEVER
|
|
|
899 @end example
|
|
|
900
|
|
|
901 Then (fingers crossed) it should compile and it will use netaudio if you
|
|
|
902 have a server running corresponding to the X server. The netaudio server
|
|
|
903 has to be there when XEmacs starts. If the netaudio server goes away and
|
|
|
904 another is run, XEmacs should cope (fingers crossed, error handling in
|
|
|
905 netaudio isn't perfect).
|
|
|
906
|
|
|
907 BTW, netaudio has been renamed as it has a name clash with something
|
|
|
908 else, so if you see references to NAS or Network Audio System, it's the
|
|
|
909 same thing. It also might be found at
|
|
|
910 <URL:ftp.x.org:/contrib/audio/nas/>.

1077 That's correct [The SunOS 4.1.3 precompiled binaries don't do name
|

|
|

1079 (that DNS thing was apparently only a passing fad, right?), the stock

1080 SunOS 4.x systems don't have DNS-based name lookups in libc.

1081
|

1082 This is also why Netscape ships two binaries for SunOS 4.1.x.
|
|
|
1083
|
|
|
1084 The best solution is to compile it yourself; the configure script will
|

1086 to link against the DNS resolver library code.

1095 Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
|
|
|
1096 link gives you a bare-boned emacs (called temacs). temacs is then run,
|
|
|
1097 preloading some of the lisp files. The result is then dumped into a new
|
|
|
1098 executable, named xemacs, which will contain all of the preloaded lisp
|
|
|
1099 functions and data.
|
|
|
1100
|
|
|
1101 Now, during the dump itself, the executable (code+data+symbols) is
|
|
|
1102 written on disk using a special unexec() function. This function is
|
|
|
1103 obviously heavily system dependent. And on some systems, it leads to an
|
|
|
1104 executable which, although valid, cannot be stripped without damage. If
|
|
|
1105 memory serves, this is especially the case for AIX binaries. On other
|
|
|
1106 architecture it might work OK.
|
|
|
1107
|
|
|
1108 The Right Way to strip the emacs binary is to strip temacs prior to
|
|
|
1109 dumping xemacs. This will always work, although you can do that only if
|
|
|
1110 you install from sources (as temacs is @file{not} part of the binary
|
|
|
1111 kits).

1180 @section Help! XEmacs just crashed on me!
|

|
1181
|
|
|
1182 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
163
|
1183 hard to auto-save all of your files before dying. (The main time that
|
|
82
|
1184 this will not happen is if the machine physically lost power or if you
|
|
163
|
1185 killed the XEmacs process using @code{kill -9}). The next time you try
|
|
82
|
1186 to edit those files, you will be informed that a more recent auto-save
|
|
|
1187 file exists. You can use @kbd{M-x recover-file} to retrieve the
|
|
|
1188 auto-saved version of the file.
|
|
|
1189
|
|
|
1190 Starting with 19.14, you may use the command @kbd{M-x recover-session}
|
|
|
1191 after a crash to pick up where you left off.
|
|
|
1192
|
|
|
1193 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
1194 particular sequences of actions, that cause it to crash. If you can
|
|
|
1195 come up with a reproducible way of doing this (or even if you have a
|
|
|
1196 pretty good memory of exactly what you were doing at the time), the
|
|
|
1197 maintainers would be very interested in knowing about it. Post a
|
|
|
1198 message to comp.emacs.xemacs or send mail to <crashes@@xemacs.org>.
|
|
|
1199 Please note that the @samp{crashes} address is exclusively for crash
|
|
|
1200 reports.
|
|
|
1201
|
|
|
1202 If at all possible, include a stack backtrace of the core dump that was
|
|
|
1203 produced. This shows where exactly things went wrong, and makes it much
|
|
|
1204 easier to diagnose problems. To do this, you need to locate the core
|
|
|
1205 file (it's called @file{core}, and is usually sitting in the directory
|
|
|
1206 that you started XEmacs from, or your home directory if that other
|
|
|
1207 directory was not writable). Then, go to that directory and execute a
|
|
|
1208 command like:
|
|
|
1209
|
|
|
1210 @example
|
|
|
1211 gdb `which xemacs` core
|
|
|
1212 @end example
|
|
|
1213
|
|
|
1214 and then issue the command @samp{where} to get the stack backtrace. You
|
|
|
1215 might have to use @code{dbx} or some similar debugger in place of
|
|
|
1216 @code{gdb}. If you don't have any such debugger available, complain to
|
|
|
1217 your system administrator.
|
|
|
1218
|
|
|
1219 It's possible that a core file didn't get produced, in which case you're
|
|
|
1220 out of luck. Go complain to your system administrator and tell him not
|
|
|
1221 to disable core files by default. Also @xref{Q2.1.15} for tips and
|

1281 @section Translation Table Syntax messages at Startup
|
|

1282

1283 I get tons of translation table syntax error messages during startup.
|
|
|
1284 How do I get rid of them?
|
|
|
1285
|
|
|
1286 There are two causes of this problem. The first usually only strikes
|
|
|
1287 people using the prebuilt binaries. The culprit in both cases is the
|
|
|
1288 file @file{XKeysymDB}.
|
|
|
1289
|
|
|
1290 @itemize @bullet
|
|
|
1291 @item
|
|
|
1292 The binary cannot find the @file{XKeysymDB} file. The location is
|
|
|
1293 hardcoded at compile time so if the system the binary was built on puts
|
|
|
1294 it a different place than your system does, you have problems. To fix,
|
|
|
1295 set the environment variable @var{XKEYSYMDB} to the location of the
|
|
|
1296 @file{XKeysymDB} file on your system or to the location of the one
|
|
|
1297 included with XEmacs which should be at
|
|
126
|
1298 @file{<xemacs_root_directory>/lib/xemacs-19.15/etc/XKeysymDB}.
|
|
82
|
1299
|
|
|
1300 @item
|
|
|
1301 The binary is finding the XKeysymDB but it is out-of-date on your system
|
|
|
1302 and does not contain the necessary lines. Either ask your system
|
|
|
1303 administrator to replace it with the one which comes with XEmacs (which
|
|
|
1304 is the stock R6 version and is backwards compatible) or set your
|
|
|
1305 @var{XKEYSYMDB} variable to the location of XEmacs's described above.

1311 How can I avoid the startup warnings about deducing proper fonts?
|
|
|
1312
|
|
|
1313 This is highly dependent on your installation, but try with the
|
|
|
1314 following font as your base font for XEmacs and see what it does:
|
|
|
1315
|
|
|
1316 @example
|
|
|
1317 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
|
1318 @end example
|
|
|
1319
|
|
|
1320 More precisely, do the following in your resource file:
|
|
|
1321
|
|
|
1322 @example
|
|
|
1323 Emacs.default.attributeFont: -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
16
|
1324 @end example
|
|
|
1325
|
|
82
|
1326 If you just don't want to see the @samp{*Warnings*} buffer at startup
|
|
|
1327 time, you can set this:
|
|
|
1328
|
|
|
1329 @lisp
|
|
|
1330 (setq display-warning-minimum-level 'error)
|
|
|
1331 @end lisp
|
|
|
1332
|
|
|
1333 The buffer still exists; it just isn't in your face.

1551 If XEmacs does crash on you, one of the most productive things you can
|
|
|
1552 do to help get the bug fixed is to poke around a bit with the debugger.
|

1555 @itemize @bullet

|
|
|
1557 First of all, if the crash is at all reproducible, consider very
|
|
|
1558 strongly recompiling your XEmacs with debugging symbols, with no
|
|
|
1559 optimization, and with the configure options @samp{--debug=yes},
|
|
|
1560 @samp{--error-checking=all}, and @samp{--dynamic=no}. This will make
|
|
|
1561 your XEmacs run somewhat slower but make it a lot more likely to catch
|
|
|
1562 the problem earlier (closer to its source), and a lot easier to
|
|
|
1563 determine what's going on with a debugger.
|
|
|
1564
|
|
|
1565 @item
|
|
|
1566 If you're able to run XEmacs under a debugger and reproduce the crash
|
|
|
1567 (if it's inconvenient to do this because XEmacs is already running or is
|
|
|
1568 running in batch mode as part of a bunch of scripts, consider attaching
|
|
|
1569 to the existing process with your debugger; most debuggers let you do
|
|
|
1570 this by substituting the process ID for the core file when you invoke
|
|
|
1571 the debugger from the command line, or by using the @code{attach}
|
|
|
1572 command or something similar), here are some things you can do:
|
|
|
1573
|
|
|
1574 @item
|
|
|
1575 If XEmacs is hitting an assertion failure, put a breakpoint on
|
|
|
1576 @code{assert_failed()}.
|
|
|
1577
|
|
|
1578 @item
|
|
|
1579 If XEmacs is hitting some weird Lisp error that's causing it to crash
|
|
|
1580 (e.g. during startup), put a breakpoint on @code{signal_1()}---this is
|
|

1581 declared static in eval.c.

1583 @item
|
|

1584 Internally, you will probably see lots of variables that hold objects of
|
|
|
1585 type @code{Lisp_Object}. These are exactly what they appear to be,
|
|
|
1586 i.e. references to Lisp objects. Printing them out with the debugger
|
|
|
1587 probably won't be too useful---you'll just see a number. To decode
|
|
|
1588 them, do this:
|
|
|
1589
|
|
|
1590 @example
|
|
|
1591 call debug_print (OBJECT)
|
|
|
1592 @end example
|
|
|
1593
|
|
|
1594 where @var{OBJECT} is whatever you want to decode (it can be a variable,
|
|
|
1595 a function call, etc.). This will print out a readable representation
|
|
|
1596 on the TTY from which the xemacs process was invoked.
|
|
|
1597
|
|
|
1598 @item
|
|
|
1599 If you want to get a Lisp backtrace showing the Lisp call
|
|
|
1600 stack, do this:
|
|
|
1601
|
|
|
1602 @example
|
|
|
1603 call debug_backtrace ()
|
|

1609 file @file{gdbinit} in the @file{src} directory of the XEmacs

1610 distribution that should make it easier for you to decode Lisp objects.

1617 If you're using a debugger to get a C stack backtrace and you're seeing
|
|
|
1618 stack traces with some of the innermost frames mangled, it may be due to
|
|
|
1619 dynamic linking. (This happens especially under Linux.) Consider
|
|
|
1620 reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
|
|
|
1621 Linux), stack backtraces of core dumps will have the frame where the
|
|
|
1622 fatal signal occurred mangled; if you can obtain a stack trace while
|
|
|
1623 running the XEmacs process under a debugger, the stack trace should be
|
|
|
1624 clean.

1626 Curtiss <1CMC3466@@ibm.mtsac.edu> suggests upgrading to ld.so version 1.8

1630 If you're using a debugger to get a C stack backtrace and you're
|
|
|
1631 getting a completely mangled and bogus stack trace, it's probably due to
|
|
|
1632 one of the following:

1636 Your executable has been stripped. Bad news. Tell your sysadmin not to

1637 do this---it doesn't accomplish anything except to save a bit of disk
|

1638 space, and makes debugging much much harder.

|

1641 Your stack is getting trashed. Debugging this is hard; you have to do a
|
|
|
1642 binary-search-type of narrowing down where the crash occurs, until you
|
|
|
1643 figure out exactly which line is causing the problem. Of course, this
|
|
|
1644 only works if the bug is highly reproducible.

1647 If your stack trace has exactly one frame in it, with address 0x0, this
|
|
|
1648 could simply mean that XEmacs attempted to execute code at that address,
|
|
|
1649 e.g. through jumping to a null function pointer. Unfortunately, under
|
|
|
1650 those circumstances, GDB under Linux doesn't know how to get a stack
|
|
|
1651 trace. (Yes, this is the third Linux-related problem I've mentioned. I
|
|
|
1652 have no idea why GDB under Linux is so bogus. Complain to the GDB
|
|
|
1653 authors, or to comp.os.linux.development.system). Again, you'll have to
|
|
|
1654 use the narrowing-down process described above.

1657 If you compiled 19.14 with @samp{--debug} (or by default in later
|
|
|
1658 versions), you will get a Lisp backtrace output when XEmacs crashes, so
|
|
|
1659 you'll have something useful. If you're in 19.13, you could try doing
|
|
|
1660 @code{call debug_backtrace()}---sometimes this works even after a fatal
|
|
|
1661 signal has been received.

1666 Here's some more info about using gdbinit:
|
|
|
1667
|
|
|
1668 Different version of @code{gdbinit} are provided for different
|
|
|
1669 platforms. One of these should be installed as @file{.gdbinit} in your
|
|
|
1670 home directory. If you're using XEmacs 19.14 or better, you should
|
|
|
1671 install the default @code{gdbinit} in the @file{src/} directory if you
|
|
|
1672 have GDB 4.14 or better. With GDB 4.13 or earlier, install
|
|
|
1673 @file{gdbinit.pre-4.14}; however, this is noticeably harder to use. If
|
|
|
1674 you're on a machine that uses a union type for Lisp_Objects (only the
|
|
|
1675 DEC Alpha, I think), you'll have to use @code{gdbinit.union}, which is
|
|
|
1676 of the pre-4.14 variety but should be easily upgradable.
|
|
|
1677
|
|
|
1678 With XEmacs 19.13 and earlier, only one @code{gdbinit} is provided (I
|
|
|
1679 think); it's of the pre-4.14 variety and of the union-type
|
|
|
1680 variety. (Many more machines used the union type under 19.13).
|
|
|
1681
|
|
|
1682 With the GDB 4.14+ gdbinit, you can print out a Lisp_Object using
|
|
|
1683 @code{p1 OBJECT} (which calls @code{debug_print()}, and hence only works
|
|
|
1684 if you have a running process) or @code{frob OBJECT} (which works even
|
|
|
1685 on core dumps, and does its own decoding of the object, but its output
|
|
|
1686 isn't always so convenient).
|
|
|
1687
|
|
|
1688 With the pre-GDB 4.14 gdbinit, you have to do these steps:
|
|
|
1689
|
|
|
1690 @example
|
|
|
1691 print OBJECT
|
|
|
1692 xtype
|
|
|
1693 <then type "xcons" or "xstring" or whatever, depending on the type>
|
|
|
1694 @end example
|
|
|
1695
|
|
|
1696 If the object is a record type, you'll probably have to the following
|
|
|
1697 steps:
|
|
|
1698
|
|
|
1699 @example
|
|
|
1700 print OBJECT
|
|
|
1701 xtype
|
|
|
1702 xrecord
|
|
|
1703 <remember what type is printed>
|
|
|
1704 print OBJECT
|
|
|
1705 <then type "xbuffer" or "xsymbol" or whatever>
|
|
|
1706 @end example
|
|
|
1707
|
|
|
1708 Of course, if you know in advance what type the object is of, you can
|
|
|
1709 omit all but the last two steps.

1758 For the record, compiling on hpux 10.10 leads to a hang in Gnus when

1759 compiled with optimization on.
|

|
1760
|
|
|
1761 I've just discovered that my hpux 10.01 binary was working less well
|
|
|
1762 than expected. In fact, on a 10.10 system, @code{(while t)} was not
|
|
|
1763 interupted by @kbd{C-g}. I defined @code{BROKEN_SIGIO} and recompiled on
|
|
|
1764 10.10, and... the hang is now gone.
|
|
|
1765
|
|
|
1766 As far as configure goes, this will be a bit tricky: @code{BROKEN_SIGIO}
|
|
|
1767 is needed on 10.10, but @strong{not} on 10.01: if I run my 10.01 binary
|
|
|
1768 on a 10.01 machine, without @code{BROKEN_SIGIO} being defined, @kbd{C-g}

1839 Two things you can do:

|
|
|
1841 1) C level:
|
|
|
1842
|
|
|
1843 When you see it going mad like this, you might want to use gdb from an
|
|
|
1844 'xterm' to attach to the running process and get a stack trace. To do
|
|
|
1845 this just run:
|
|
|
1846
|
|
|
1847 @example
|
|
|
1848 gdb /path/to/xemacs/xemacs ####
|
|
|
1849 @end example
|
|
|
1850
|
|
163
|
1851 Where @code{####} is the process id of your xemacs, instead of
|
|
|
1852 specifying the core. When gdb attaches, the xemacs will stop [1] and
|
|
|
1853 you can type `where' in gdb to get a stack trace as usual. To get
|
|
|
1854 things moving again, you can just type `quit' in gdb. It'll tell you
|
|
|
1855 the program is running and ask if you want to quit anyways. Say 'y' and
|
|
|
1856 it'll quit and have your emacs continue from where it was at.
|
|
116
|
1857
|
|
|
1858 2) Lisp level:
|
|
|
1859
|
|
|
1860 Turn on debug-on-quit early on. When you think things are going slow
|
|
|
1861 hit C-g and it may pop you in the debugger so you can see what routine
|
|
|
1862 is running. Press `c' to get going again.
|
|
|
1863
|
|
|
1864 debug-on-quit doesn't work if something's turned on inhibit-quit or in
|
|

2225 @section @samp{xemacs -name junk} doesn't work?
|
|
|
2226
|
|
|
2227 When I run @samp{xterm -name junk}, I get an xterm whose class name
|
|
|
2228 according to xprop, is @samp{junk}. This is the way it's supposed to
|
|
|
2229 work, I think. When I run @samp{xemacs -name junk} the class name is
|
|
|
2230 not set to @samp{junk}. It's still @samp{emacs}. What does
|
|
|
2231 @samp{xemacs -name} really do? The reason I ask is that my window
|
|
|
2232 manager (fvwm) will make a window sticky and I use XEmacs to read my
|
|
|
2233 mail. I want that XEmacs window to be sticky, without having to use the
|
|
|
2234 window manager's function to set the window sticky. What gives?
|
|
|
2235
|
|
|
2236 @samp{xemacs -name} sets the application name for the program (that is,
|
|
|
2237 the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
|
|
|
2238 is the same as making a copy of the executable with that new name. The
|
|
|
2239 @code{WM_CLASS} property on each frame is set to the frame-name, and the
|
|
|
2240 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
2241 created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
|
|
|
2242 @code{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
2243 widget would be:
|
|
|
2244
|
|
|
2245 @example
|
|
|
2246 Name: FOO .shell .container .BAR
|
|
|
2247 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2248 @end example
|
|
|
2249
|
|
|
2250 instead of the default
|
|
|
2251
|
|
|
2252 @example
|
|
|
2253 Name: xemacs.shell .container .emacs
|
|
|
2254 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2255 @end example
|
|
|
2256
|
|
|
2257
|
|
|
2258 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
2259 application-name instead of the frame-name, but I think that's less
|
|
|
2260 flexible, since it does not give you the ability to have multiple frames
|
|
|
2261 with different WM_CLASS properties. Another possibility would be for
|
|
|
2262 the default frame name to come from the application name instead of
|
|
|
2263 simply being @samp{emacs}. However, at this point, making that change
|
|
|
2264 would be troublesome: it would mean that many users would have to make
|
|
|
2265 yet another change to their resource files (since the default frame name
|
|
|
2266 would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
|
|
|
2267 the executable happened to be named), so we'd rather avoid it.
|
|
|
2268
|
|
|
2269 To make a frame with a particular name use:
|
|
|
2270
|
|
|
2271 @lisp
|
|
|
2272 (make-frame '((name . "the-name")))

2362 @section How can I limit color map usage?
|
|
|
2363
|
|
|
2364 I'm using Netscape (or another color grabber like XEmacs);
|
|
|
2365 is there anyway to limit the number of available colors in the color map?
|
|
|
2366
|
|
126
|
2367 XEmacs 19.13 didn't have such a mechanism (unlike netscape, or other
|
|
82
|
2368 color-hogs). One solution is to start XEmacs prior to netscape, since
|
|
|
2369 this will prevent Netscape from grabbing all colors (but Netscape will
|
|
|
2370 complain). You can use the flags for Netscape, like -mono, -ncols <#>
|
|
|
2371 or -install (for mono, limiting to <#> colors, or for using a private
|
|
|
2372 color map). Since Netscape will take the entire colormap and never
|
|
|
2373 release it, the only reasonable way to run it is with @samp{-install}.
|
|
|
2374
|
|
|
2375 If you have the money, another solution would be to use a truecolor or
|
|
|
2376 direct color video.
|
|
|
2377
|
|
|
2378 Starting with XEmacs 19.14, XEmacs uses the closest available color if
|
|
|
2379 the colormap is full, so it's O.K. now to start Netscape first.

|
2526 As an example, say you want the @kbd{paste} key on a Sun keyboard to
|
|
|
2527 insert the current Primary X selection at point. You can accomplish this
|
|
|
2528 with:
|
|
|
2529
|
|
|
2530 @lisp
|
|
|
2531 (define-key global-map [f18] 'x-insert-selection)
|
|
|
2532 @end lisp
|
|
|
2533
|
|
|
2534 However, this only works if there is a current X selection (the
|
|
|
2535 selection will be highlighted). The functionality I like is for the
|
|
|
2536 @kbd{paste} key to insert the current X selection if there is one,
|
|
|
2537 otherwise insert the contents of the clipboard. To do this you need to
|
|
|
2538 pass arguments to @code{x-insert-selection}. This is done by wrapping
|
|
|
2539 the call in a 'lambda form:
|
|
|
2540
|
|
|
2541 @lisp
|
|
163
|
2542 (global-set-key [f18]
|
|
|
2543 (lambda () (interactive) (x-insert-selection t nil)))
|
|
82
|
2544 @end lisp
|
|
|
2545
|
|
|
2546 This binds the f18 key to a @dfn{generic} functional object. The
|
|
|
2547 interactive spec is required because only interactive functions can be
|
|
163
|
2548 bound to keys.
|
|
82
|
2549
|
|
|
2550 For the FAQ example you could use:
|
|
|
2551
|
|
|
2552 @lisp
|
|
|
2553 (global-set-key [(control ?.)]
|
|
163
|
2554 (lambda () (interactive) (scroll-up 1)))
|
|
82
|
2555 (global-set-key [(control ?;)]
|
|
163
|
2556 (lambda () (interactive) (scroll-up -1)))
|
|
82
|
2557 @end lisp
|
|
|
2558
|
|
|
2559 This is fine if you only need a few functions within the lambda body.
|
|
|
2560 If you're doing more it's cleaner to define a separate function as in
|
|
|

2615

2616 New in XEmacs 19.14 is a variable called @code{key-translation-map}

2892 It actually doesn't. It leaves the region visible for a second so that

2893 you can see what area is being yanked. If you start working, though, it

|
|
|
2993
|
|

2999 function:
|
|

3000

3004
|
|
|
3005 You can actually turn the scrollbars on at any level you want by
|
|
|
3006 substituting for (selected-frame) in the above command. For example, to
|
|
|
3007 turn the scrollbars off only in a single buffer:
|
|

3008
|
|

3041 When I move the scrollbar in an XEmacs window, it moves the point as
|

|
3042 well, which should not be the default behavior. Is this a bug or a
|
|
|
3043 feature? Can I disable it?
|
|
|
3044
|
|
|
3045 The current behavior is a feature, not a bug. Point remains at the same
|
|
|
3046 buffer position as long as that position does not scroll off the screen.
|
|
|
3047 In that event, point will end up in either the upper-left or lower-left

|
|
3048 hand corner.

|

3055 By the same token, how can I turn it off in specific modes?
|
|

3056

3058

3059 @lisp

3060 (require 'auto-show)
|
|

|
3062
|
|
|
3063 Then do @code{(setq truncate-lines t)} in the mode-hooks for any modes
|
|
|
3064 in which you want lines truncated.
|
|
|
3065
|
|
|
3066 More precisely: If @code{truncate-lines} is nil, horizontal scrollbars
|
|
|
3067 will never appear. Otherwise, they will appear only if the value of
|
|
|
3068 @code{scrollbar-height} for that buffer/window/etc. is non-zero. If you

3069 do

|
|

3073 @end lisp
|

3074

3075 then horizontal scrollbars will not appear in truncated buffers unless
|
|

3100

3349 @code{/bin/mail} using the protocol defined by @code{/bin/mail}.
|
|
|
3350
|
|
|
3351 There are two different protocols in general use. One of them uses the
|
|
|
3352 @code{flock} system call. The other involves creating a lock file;
|
|
|
3353 @code{movemail} must be able to write in @file{/usr/spool/mail} in order
|
|
|
3354 to do this. You control which one is used by defining, or not defining,
|
|
|
3355 the macro @code{MAIL_USE_FLOCK} in @file{config.h} or the m- or s- file
|
|
|
3356 it includes.

3363 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a

3365 root):

3383 Installation normally copies movemail from the build directory to an

3384 installation directory which is usually under @file{/usr/local/lib}.
|
|
|
3385 The installed copy of @code{movemail} is usually in the directory
|
|
|
3386 @file{/usr/local/lib/emacs/VERSION/TARGET}. You must change the group

3387 and mode of the installed copy; changing the group and mode of the build

3538
|
|

3539 TM stands for @dfn{Tools for MIME} and not Tiny MIME. TM integrates
|
|
|
3540 with all major XEmacs packages like Gnus (all flavors), VM, MH-E, and
|
|
|
3541 mailcrypt. It provides totally transparent and trouble-free MIME
|
|
|
3542 support. When appropriate a message will be decoded in place in an
|
|
|
3543 XEmacs buffer.
|
|
|
3544
|
|

|
3545 TM now comes as a package with XEmacs 19.15 and XEmacs 20.0.

3547 TM was written by MORIOKA Tomohiko <morioka@@jaist.ac.jp> and KOBAYASHI
|
|
|
3548 Shuhei <shuhei-k@@jaist.ac.jp>. It is based on the work of UMEDA

3681 InfoDock is an integrated productivity toolset, mainly aimed at
|
|
86
|
3682 technical people. It is developed and supported by InfoDock
|
|
|
3683 Associates, a firm that offers custom support and development
|
|
|
3684 for InfoDock, XEmacs and GNU Emacs. (http://www.infodock.com,
|
|
88
|
3685 <info@@infodock.com>, +1 408 243 3300).
|
|
86
|
3686
|
|
|
3687 InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
|
|
|
3688 the power of Emacs, but with an easier to use and more comprehensive
|
|
|
3689 menu-based user interface. The bottom portion of this text describes
|
|
|
3690 how it differs from XEmacs and GNU Emacs from the Free Software
|
|
|
3691 Foundation.

|
3692
|
|
|
3693 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
3694 environment. Although InfoDock is customizable, it is not intended for
|
|
|
3695 people who like basic versions of Emacs which need to be customized
|
|
|
3696 extensively for local use; standard Emacs distributions are better for
|
|
|
3697 such uses. InfoDock is for those people who want a complete,
|
|
|
3698 pre-customized environment in one package, which they need not touch
|
|
|
3699 more than once or twice a year to update to new revisions.
|
|
|
3700
|
|
86
|
3701 InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
|
|
|
3702 and Intel Linux systems. It is intended for use on a color display,
|
|
|
3703 although most features will work on monochrome monitors. Simply unpack
|
|
|
3704 InfoDock according to the instructions in the ID-INSTALL file and you
|
|
|
3705 are ready to run.

|
|
|
3836
|
|
|
3837 AUC TeX is a package written by Per Abrahamsen <abraham@@dina.kvl.dk>.
|
|
|
3838 Starting with XEmacs 19.15, AUC TeX is bundled with XEmacs. The
|
|
|
3839 following information is from the @file{README} and website.
|
|
82
|
3840
|
|
|
3841 AUC TeX is an extensible package that supports writing and formatting
|
|
|
3842 TeX files for most variants of GNU Emacs. Many different macro packages
|
|
|
3843 are supported, including AMS TeX, LaTeX, and TeXinfo.
|
|
|
3844
|
|
|
3845 The most recent version is always available by ftp at
|
|
|
3846 <URL:ftp://sunsite.auc.dk/packages/auctex/auctex.tar.gz>.
|
|
|
3847
|
|

3848 In case you don't have access to anonymous ftp, you can get it by an

3903 @section Is there a reason for an Emacs package not to be included in XEmacs?
|
|
|
3904
|
|
|
3905 The reason for an Emacs package not to be included in XEmacs is
|
|
|
3906 usually one or more of the following:
|
|
|
3907
|
|
|
3908 @enumerate
|
|
|
3909 @item
|
|
|
3910 The package has not been ported to XEmacs. This will typically happen
|
|
|
3911 when it uses GNU-Emacs-specific features, which make it fail under
|
|
|
3912 XEmacs.
|
|
|
3913
|
|
|
3914 Porting a package to XEmacs can range from a trivial amount of change to
|
|
|
3915 a partial or full rewrite. Fortunately, the authors of modern packages
|
|
|
3916 usually choose to support both Emacsen themselves.
|
|
|
3917
|
|
|
3918 @item
|
|
|
3919 The package has been decided not to be appropriate for XEmacs. It may
|
|
|
3920 have an equivalent or better replacement within XEmacs, in which case
|
|
|
3921 the developers may choose not to burden themselves with supporting an
|
|
|
3922 additional package.
|
|
|
3923
|
|
|
3924 Each package bundled with XEmacs means more work for the maintainers,
|
|
|
3925 whether they want it or not. If you are ready to take over the
|
|
|
3926 maintainence responsibilities for the package you port, be sure to say
|
|
|
3927 so -- we will more likely include it.

3929 @item
|
|
|
3930 The package simply hasn't been noted by the XEmacs development. If
|
|
|
3931 that's the case, the messages like yours are very useful for attracting
|
|
|
3932 our attention.

3934 @item

3935 The package was noted by the developers, but they simply haven't yet

3936 gotten around to including/porting it. Wait for the next release or,

3937 even better, offer your help. It will be gladly accepted and

4019
|
|
|
4020 Well, first off, consider if you really want to do this. cc-mode is
|
|
|
4021 much more powerful than the old c-mode. If you're having trouble
|
|
|
4022 getting your old offsets to work, try using @code{c-set-offset} instead.

4023 You might also consider using the package @code{cc-compat}.

4024

4326 Emacs has a legacy of keyboards that produced characters with modifier
|
|
|
4327 bits, and therefore map a variety of input systems into this scheme even
|
|
|
4328 today. XEmacs is instead optimized for X events. This causes an
|
|
|
4329 incompatibility in the way key sequences are specified, but both Emacs
|
|
|
4330 and XEmacs will accept a key sequence as a vector of lists of modifiers
|
|
163
|
4331 that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
|
|
|
4332 @code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
|
|
|
4333 form for a single key, just (meta control a). Emacs has an abbreviated
|
|
|
4334 form for the Control and the Meta modifiers to string-characters (the
|
|
|
4335 ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
|
|
|
4336 that the abbreviated form works only for one-character key sequences,
|
|
|
4337 while Emacs users need to be aware that the string-character is rather
|
|
|
4338 limited. Specifically, the string-character can accomodate only 256
|
|
|
4339 different values, 128 of which have the Meta modifier and 128 of which
|
|
|
4340 have not. In each of these blocks, only 32 characters have the Control
|
|
|
4341 modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
|
|
|
4342 control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
|
|
|
4343 do not. Programmers are advised to use the full common form, both
|
|
|
4344 because it is more readable and less error-prone, and because it is
|
|
|
4345 supported by both Emacsen.

4412 A word in angle brackets, e.g., @code{<return>}, @code{<down>}, or
|
|
|
4413 @code{<f1>}, represents a function key. (Note that in the standard
|
|
|
4414 configuration, the function key @code{<return>} and the control key
|
|
|
4415 @kbd{RET} are synonymous.) You can use angle brackets on the words
|

4416 @kbd{RET}, @kbd{SPC}, etc., but they are not required there.

4419 Keys can be written by their @sc{ascii} code, using a backslash followed
|

4420 by up to six octal digits. This is the only way to represent keys with

4421 codes above \377.

|
|
4425 (shift), @kbd{A-} (alt), @kbd{H-} (hyper), and @kbd{s-} (super) may
|
|
|
4426 precede a character or key notation. For function keys, the prefixes
|
|
|
4427 may go inside or outside of the brackets: @code{C-<down>} @equiv{}
|
|
|
4428 @code{<C-down>}. The prefixes may be written in any order: @kbd{M-C-x}
|
|
|
4429 @equiv{} @kbd{C-M-x}.
|
|
|
4430
|
|
|
4431 Prefixes are not allowed on multi-key words, e.g., @kbd{C-abc}, except
|
|
|
4432 that the Meta prefix is allowed on a sequence of digits and optional
|
|
|
4433 minus sign: @kbd{M--123} @equiv{} @kbd{M-- M-1 M-2 M-3}.
|

|
|

4443 @item

4452 Multiple text keys can normally be strung together to form a word, but
|
|
|
4453 you may need to add whitespace if the word would look like one of the
|
|
|
4454 above notations: @code{; ; ;} is a keyboard macro with three semicolons,
|
|
|
4455 but @code{;;;} is a comment. Likewise, @code{\ 1 2 3} is four keys but
|
|
|
4456 @code{\123} is a single key written in octal, and @code{< right >} is
|
|
|
4457 seven keys but @code{<right>} is a single function key. When in doubt,
|
|
|
4458 use whitespace.

4475 @item Global variables
|
|
|
4476
|
|

4477 You will typically @code{defvar} your global variable to a default
|
|
|
4478 value, and use @code{setq} to set it later.
|
|
|
4479
|
|
|
4480 It is never a good practice to @code{setq} user variables (like
|
|
|
4481 @code{case-fold-search}, etc.), as it ignores the user's choice
|
|
|
4482 unconditionally. Note that @code{defvar} doesn't change the value of a
|
|
|
4483 variable if it was bound previously. If you wish to change a
|
|
|
4484 user-variable temporarily, use @code{let}:
|
|
82
|
4485
|
|
|
4486 @lisp
|
|
163
|
4487 (let ((case-fold-search nil))

|
|
82
|
4490 @end lisp

4492 You will notice the user-variables by their docstrings beginning with an

4495 @item Local variables
|
|

4496
|

4497 Bind them with @code{let}, which will unbind them (or restore their
|
|
|
4498 previous value, if they were bound) after exiting from the @code{let}
|
|
|
4499 form. Change the value of local variables with @code{setq} or whatever
|
|
|
4500 you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
|
|
|
4501 can even return one of its local variables.
|
|
|
4502
|
|
|
4503 Typical usage:
|
|
82
|
4504
|
|
|
4505 @lisp
|
|
163
|
4506 ;; iterate through the elements of the list returned by

|
|
|
4509 (while l
|
|

4510 ... do something with (car l) ...
|
|
|
4511 (setq l (cdr l))))
|
|
|
4512 @end lisp
|
|
|
4513
|
|
|
4514 Another typical usage includes building a value simply to work with it.
|

4516 @lisp

|
|
|
4522 @end lisp

4524 This piece of code uses the local variable @code{inbox}, which becomes

|
4525 unbound (or regains old value) after exiting the form. The form also
|
|
|
4526 returns the value of @code{inbox}, which can be reused, for instance:

|
4527
|

4535 @section What is the typical misuse of @code{setq} ?
|
|
|
4536
|
|
|
4537 A typical misuse is probably @code{setq}ing a variable that was meant to
|
|
|
4538 be local. Such a variable will remain bound forever, never to be
|
|
|
4539 garbage-collected. For example, the code doing:
|
|
|
4540
|
|
|
4541 @lisp
|
|
|
4542 (defun my-function (whatever)
|
|
|
4543 (setq a nil)
|
|
|
4544 ... build a large list ...
|
|
|
4545 ... and exit ...)
|
|
|
4546 @end lisp
|
|
|
4547
|
|
|
4548 does a bad thing, as @code{a} will keep consuming memory, never to be
|
|
|
4549 unbound. The correct thing is to do it like this:
|
|
|
4550
|
|
|
4551 @lisp
|
|
|
4552 (defun my-function (whatever)
|
|
|
4553 (let (a) ; default initialization is to nil
|
|
|
4554 ... build a large list ...
|
|
|
4555 ... and exit, unbinding `a' in the process ...)
|
|
|
4556 @end lisp
|
|
|
4557
|
|
|
4558 Not only is this prettier syntactically, but it makes it possible for
|
|
|
4559 Emacs to garbage-collect the objects which @code{a} used to reference.
|
|
|
4560
|
|
|
4561 Note that even global variables should not be @code{setq}ed without
|
|
|
4562 @code{defvar}ing them first, because the byte-compiler issues warnings.
|
|
|
4563 The reason for the warning is the following:
|
|
|
4564
|
|
|
4565 @lisp
|
|
|
4566 (defun flurgoze nil) ; ok, global internal variable
|
|
|
4567 ...
|
|
|
4568
|
|
|
4569 (setq flurghoze t) ; ops! a typo, but semantically correct.
|
|
|
4570 ; however, the byte-compiler warns.
|
|
|

4583 Many of the advanced features of this package, such as @code{defun*},
|
|
|
4584 @code{loop}, and @code{setf}, are implemented as Lisp macros. In
|
|
|
4585 byte-compiled code, these complex notations will be expanded into
|
|
|
4586 equivalent Lisp code which is simple and efficient. For example, the
|
|
|
4587 forms
|
|
82
|
4588

4589 @lisp
|
|

4601 which are the most efficient ways of doing these respective operations
|
|
|
4602 in Lisp. Thus, there is no performance penalty for using the more
|
|
|
4603 readable @code{incf} and @code{push} forms in your compiled code.
|
|
|
4604
|
|
|
4605 @emph{Interpreted} code, on the other hand, must expand these macros
|
|
|
4606 every time they are executed. For this reason it is strongly
|
|
|
4607 recommended that code making heavy use of macros be compiled. (The
|
|
|
4608 features labelled @dfn{Special Form} instead of @dfn{Function} in this
|
|
|
4609 manual are macros.) A loop using @code{incf} a hundred times will
|
|
|
4610 execute considerably faster if compiled, and will also garbage-collect
|
|
|
4611 less because the macro expansion will not have to be generated, used,
|
|
|
4612 and thrown away a hundred times.
|
|
|
4613
|
|
|
4614 You can find out how a macro expands by using the @code{cl-prettyexpand}
|
|
|
4615 function.

4622 think well whether this is a real concern in Emacs. Much of the Emacs

4703 @section How do you make XEmacs indent CL if-clauses correctly?
|
|
|
4704
|
|
|
4705 I'd like XEmacs to indent all the clauses of a Common Lisp @code{if} the
|
|
|
4706 same amount instead of indenting the 3rd clause differently from the
|
|
|
4707 first two.
|
|
70
|
4708
|
|
|
4709 One way is to add, to @file{.emacs}:
|
|
|
4710
|
|
82
|
4711 @lisp
|
|
70
|
4712 (put 'if 'lisp-indent-function nil)
|
|
82
|
4713 @end lisp
|
|
70
|
4714
|
|
|
4715 However, note that the package @file{cl-indent.el} that comes with
|
|
82
|
4716 XEmacs sets up this kind of indentation by default. @code{cl-indent}
|
|
|
4717 also knows about many other CL-specific forms. To use @code{cl-indent},
|
|
|
4718 one can do this:
|
|
|
4719
|
|
|
4720 @lisp
|
|
70
|
4721 (load "cl-indent")
|
|
|
4722 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
82
|
4723 @end lisp
|
|
|
4724
|
|
|
4725 One can also customize @file{cl-indent.el} so it mimics the default
|

|

4741 When I try to edit a postscript file it gets stuck saying:
|
|
|
4742 @samp{fontifying 'filename' (regexps....)} and it just sits there. If I
|
|
|
4743 press @kbd{C-c} in the window where XEmacs was started, it suddenly
|
|
|
4744 becomes alive again.
|
|
70
|
4745
|
|
|
4746 This was caused by a bug in the Postscript font-lock regular
|
|
82
|
4747 expressions. It was fixed in 19.13. For earlier versions of XEmacs,
|
|
|
4748 have a look at your @file{.emacs} file. You will probably have a line
|
|
|
4749 like:
|
|
|
4750
|
|
|
4751 @lisp

4756 files anymore.

4772 My printer is a Postscript printer and @code{lpr} only works for

4773 Postscript files, so how do I get @kbd{M-x lpr-region} and @kbd{M-x
|
|
|
4774 lpr-buffer} to work?
|
|
|
4775
|

4779 (setq lpr-command "a2ps")

0
|
4789
|
|
|
4790 You can specify what paths to use by using a number of different flags
|
|
|
4791 when running configure. See the section MAKE VARIABLES in the top-level
|
|
|
4792 file INSTALL in the XEmacs distribution for a listing of those flags.
|
|
|
4793
|
|
82
|
4794 Most of the time, however, the simplest fix is: @strong{do not} specify
|
|
|
4795 paths as you might for GNU Emacs. XEmacs can generally determine the
|
|
0
|
4796 necessary paths dynamically at run time. The only path that generally
|
|
|
4797 needs to be specified is the root directory to install into. That can
|
|
|
4798 be specified by passing the @code{--prefix} flag to configure. For a
|
|
82
|
4799 description of the XEmacs install tree, please consult the @file{NEWS}

4821
|

4822 Since this is XEmacs, you can specify an icon to be shown on

4825
|
|

4826 @lisp

|
|
|
4829 @end lisp
|
|
|
4830
|
|
|
4831 You can inline the @sc{xpm} definition yourself by specifying
|

|
4832 @code{:data} instead of @code{:file}. Here is such a full-featured

4884 Yes, abbrevs only expands word-syntax strings. While XEmacs does not
|
|
|
4885 prevent you from defining (e.g. with @kbd{C-x a g} or @kbd{C-x a l})
|
|
|
4886 abbrevs that contain special characters, it will refuse to expand
|
|
|
4887 them. So you need to ensure, that the abbreviation contains letters and
|
|
|
4888 digits only. This means that @samp{xd}, @samp{d5}, and @samp{5d} are
|
|
|
4889 valid abbrevs, but @samp{&d}, and @samp{x d} are not.
|
|
|
4890
|
|
|
4891 If this sounds confusing to you, (re-)read the online documentation for
|
|
|
4892 abbrevs (@kbd{C-h i m XEmacs RET m Abbrevs RET}), and then come back and
|

4893 read this question/answer again.

4920 Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,

4926 @end example
|
|
|
4927
|
|
82
|
4928 @item
|
|
|
4929 Then be sure to quote things that are necessary for emacs strings:
|
|
0
|
4930
|
|
|
4931 @example
|
|
82
|
4932 cat ./file.face | sed 's/\\/\\\\/g' | sed 's/\"/\\\"/g' > ./file.face.quoted
|
|
0
|
4933 @end example
|
|
|
4934
|
|
82
|
4935 @item
|
|
|
4936 Then set up emacs to include the file as a mail header - there were a
|
|
|
4937 couple of suggestions here---either something like:
|
|
|
4938
|
|
|
4939 @lisp
|
|
|
4940 (setq mail-default-headers
|
|
|
4941 "X-Face: <Ugly looking text string here>")
|
|
|
4942 @end lisp
|
|
|
4943
|
|
|
4944 Or, alternatively, as:
|
|
|
4945
|
|
|
4946 @lisp
|
|
|
4947 (defun mail-insert-x-face ()
|
|
|
4948 (save-excursion
|
|
|
4949 (goto-char (point-min))
|
|
|
4950 (search-forward mail-header-separator)
|
|
163
|
4951 (beginning-of-line)
|
|
82
|
4952 (insert "X-Face:")
|
|
163
|
4953 (insert-file-contents "~/.face")))
|
|
82
|
4954
|
|
|
4955 (add-hook 'mail-setup-hook 'mail-insert-x-face)
|
|
|
4956 @end lisp
|
|
|
4957 @end enumerate
|
|
|
4958
|
|
|
4959 However, 2 things might be wrong:
|
|
|
4960
|
|
|
4961 Some versions of pbmtoicon produces some header lines that is not
|
|
|
4962 expected by the version of compface that I grabbed. So I found I had to
|
|
|
4963 include a @code{tail +3} in the pipeline like this:
|
|
0
|
4964
|
|
|
4965 @example
|
|
82
|
4966 cat file.xbm | xbm2ikon | tail +3 |compface > file.face
|
|
0
|
4967 @end example
|
|
|
4968
|
|
82
|
4969 Some people have also found that if one uses the @code{(insert-file)}
|
|
|
4970 method, one should NOT quote the face string using the sed script .
|
|
|
4971
|
|
|
4972 It might also be helpful to use Stig's <stig@@hackvan.com> script
|
|
|
4973 (included in the compface distribution at XEmacs.org) to do the
|
|
|
4974 conversion. For convenience xbm2xface is available for anonymous FTP at
|
|
|
4975 <URL:ftp://ftp.miranova.com/pub/xemacs/xbm2xface.pl>.

5040 it to a printer. Something like:
|
|
|
5041
|
|
|
5042 @lisp
|
|
|
5043 (setq lpr-command "lp")
|
|
|
5044 @end lisp
|
|
|
5045
|
|
|
5046 @item lpr-switches
|
|
|
5047 This should be set to a list that contains whatever the print command
|
|
|
5048 requires to do its job. Something like:
|
|
|
5049
|
|
|
5050 @lisp
|
|
|
5051 (setq lpr-switches '("-depson"))
|
|
|
5052 @end lisp
|
|
|
5053 @end table
|
|
|
5054
|
|
|
5055 For postscript printing there are three analogous variables to
|
|
|
5056 customize.
|
|
|
5057
|
|
|
5058 @table @code
|
|
|
5059 @item ps-lpr-command
|
|
|
5060 This should be set to a command that takes postscript on standard input
|
|
|
5061 and directs it to a postscript printer.
|
|
|
5062
|
|
|
5063 @item ps-lpr-switches
|
|
|
5064 This should be set to a list of switches required for
|
|
|
5065 @code{ps-lpr-command} to do its job.
|
|
|
5066
|
|
|
5067 @item ps-print-color-p
|
|
|
5068 This boolean variable should be set @code{t} if printing will be done in
|
|
|
5069 color, otherwise it should be set to @code{nil}.
|
|
|
5070 @end table

|
5072 NOTE: It is an undocumented limitation in XEmacs that postscript
|
|
|
5073 printing (the @code{Pretty Print Buffer} menu item) @strong{requires} a
|
|
|
5074 window system environment. It cannot be used outside of X11.

|
|
|
5093
|
|
|
5094 The biggest changes in 20.2 include intergration of EFS (the next
|
|
|
5095 generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
|
|
126
|
5096 major mode for editing Tex and LaTeX, and a lot of other stuff). Many
|
|
163
|
5097 bugs from 20.0 have been fixed for this release. 20.2 also contains a
|
|
|
5098 new system for customizing XEmacs options, invoked via @kbd{M-x
|
|
|
5099 customize}.
|
|
|
5100
|
|
|
5101 XEmacs 20.2 is the development release (20.0 was beta), and is no longer
|
|
|
5102 considered unstable.

5106
|
|
|
5107 XEmacs release 20.3 is planned for autumn 1997. It will likely contain
|
|
|
5108 a much smaller amount of code for basic functionality, with all the
|
|
|
5109 popular Lisp packages being available in the form of easy-to-install
|
|
|
5110 add-ons.
|
|
|
5111
|
|
|
5112 Other input methods (such as skk) will be made available for Mule, as
|
|
|
5113 well as more user-level documentation.
|
|
|
5114
|
|
|
5115 Many new features are planned, such as multiple TTY frames, support for
|
|
|
5116 Autoconf 2, synches with Emacs 20.1, and more; much of this is already
|
|
|
5117 running in various beta versions. Ask at
|
|
|
5118 @code{<xemacs-beta-request@@xemacs.org>} for more details.

5125 Discussion about the development of XEmacs occurs on the xemacs-beta
|
|
|
5126 mailing list. Subscriptions to this list will now be fully automated
|
|
|
5127 instead of being handled by hand. Send a mail message to
|
|
|
5128 <xemacs-beta-request@@xemacs.org> with a subject of subscribe to join
|
|
|
5129 the list. Please note this is a developers mailing list for people who
|
|
|
5130 have an active interest in the development process.

5133 Due to the long development cycle in between releases, it has been
|
|
|
5134 decided that intermediate versions will be made available in source only
|
|
|
5135 form for the truly interested.
|
|
|
5136
|
|

|
5137 No further XEmacs 19 feature releases are planned. XEmacs 19.16 will
|
|
|
5138 consist of 19.15 plus the collected bugfixes, and will probably be the
|
|
|
5139 final version of XEmacs 19.
