433 Learning XEmacs is a lifelong activity. Even people who have used Emacs
|
|
|
434 for years keep discovering new features. Therefore this document cannot
|
|
|
435 be complete. Instead it is aimed at the person who is either
|
|
|
436 considering XEmacs for their own use, or has just obtained it and is
|
|
|
437 wondering what to do next. It is also useful as a reference to
|
|
|
438 available resources.

440 The previous maintainer of the FAQ was @email{rossini@@biostat.washington.edu,
|
|
428
|
441 Anthony Rossini}, who started it, after getting tired of hearing JWZ
|
|
|
442 complain about repeatedly having to answer questions.
|
|
|
443 @email{ben@@xemacs.org, Ben Wing} and @email{cthomp@@xemacs.org, Chuck
|
|
|
444 Thompson}, the principal authors of XEmacs, then took over and Ben did
|
|
|
445 a massive update reorganizing the whole thing. At which point Anthony
|
|
|
446 took back over, but then had to give it up again. Some of the other
|

447 contributors to this FAQ are listed later in this document.

511 XEmacs is a powerful, highly customizable open source text editor and
|
|
|
512 application development system, with full GUI support. It is protected
|
|
|
513 under the GNU Public License and related to other versions of Emacs, in
|
|
|
514 particular GNU Emacs. Its emphasis is on modern graphical user
|
|
|
515 interface support and an open software development model, similar to
|
|
|
516 Linux. XEmacs has an active development community numbering in the
|
|
|
517 hundreds (and thousands of active beta testers on top of this), and runs
|
|
|
518 on all versions of MS Windows, on Linux, and on nearly every other
|
|
|
519 version of Unix in existence. Support for XEmacs has been supplied by
|
|
|
520 Sun Microsystems, University of Illinois, Lucid, ETL/Electrotechnical
|
|
|
521 Laboratory, Amdahl Corporation, BeOpen, and others, as well as the
|
|
|
522 unpaid time of a great number of individual developers.

615 @unnumberedsubsec Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged?
|
|
|
616
|
|
|
617 There are currently irreconcilable differences in the views about
|
|
|
618 technical, programming, design and organizational matters between RMS
|
|
|
619 and the XEmacs development team which provide little hope for a merge to
|
|
|
620 take place in the short-term future.
|
|
|
621
|
|
|
622 If you have a comment to add regarding the merge, it is a good idea to
|
|
|
623 avoid posting to the newsgroups, because of the very heated flamewars
|
|
|
624 that often result. Mail your questions to @email{xemacs-beta@@xemacs.org} and

630 Probably the easiest way, if everything is installed, is to use Info, by

462
|
631 pressing @kbd{C-h i}, or looking for an Info item on the

632 Help Menu. @kbd{M-x apropos} can be used to look for particular commands.

913
|

914 Both the stable and development versions of XEmacs include
|
|
1135
|
915 internationalization support (aka MULE). MULE currently (21.4) works on
|
|
|
916 UNIX and Linux systems. It is possible to build with MULE on Windows
|
|
|
917 systems, but if you really need MULE on Windows, it is recommended that
|
|
|
918 you build and use the development (21.5) version, and deal with the
|
|
|
919 instability of the development tree. Binaries compiled without MULE
|
|
|
920 support run faster than MULE capable XEmacsen.

938 See question 3.5.7 (@pxref{Q3.5.7}) in part 3 of this FAQ for some

939 simple methods that also work in non-MULE builds of XEmacs (but only for

1135
|
949 The message-catalog support was written but is badly bit-rotted. XEmacs

950 20 and 21 did @emph{not} support it, and early releases of XEmacs 22
|

952
|
|
|
953 However, menubar localization @emph{does} work. To enable it, add to

954 your @file{Emacs} file entries like this:
|
|
428
|
955
|

956 @example

957 Emacs*XlwMenu.resourceLabels: True

960 @end example
|

966 @unnumberedsubsec Q1.3.5: Please explain the various input methods in MULE/XEmacs
|
|
428
|
967
|
|
1135
|
968 Mule supports a wide variety of input methods. There are three basic
|
|
|
969 classes: Lisp implementations, generic platform support, and library
|
|
|
970 interfaces.
|
|
|
971
|
|
|
972 @emph{Lisp implementations} include Quail, which provides table-driven input
|
|
|
973 methods for almost all the character sets that Mule supports (including
|
|
|
974 all of the ISO 8859 family, the Indic languages, Thai, and so on), and
|
|
|
975 SKK, for Japanese. (SKK also supports an interface to an external
|
|
|
976 "dictionary server" process.) Quail supports both typical "dead-key"
|
|
|
977 methods (eg, in the "latin-1-prefix" method, @kbd{" a} produces ä, LATIN
|
|
|
978 SMALL LETTER A WITH DIAERESIS), and the complex dictionary-based phonetic
|
|
|
979 methods used for Asian ideographic languages like Chinese.
|
|
|
980
|
|
|
981 Lisp implementations can be less powerful (but they are not perceptibly
|
|
|
982 inefficient), and of course are not portable to non-Emacs applications.
|
|
|
983 The incompatibility can be very annoying. On the other hand, they
|
|
|
984 require no special platform support or external libraries, so if you can
|
|
|
985 display the characters, Mule can input them for you and you can edit,
|
|
|
986 anywhere.
|
|
|
987
|
|
|
988 @emph{Generic platform support} is currently limited to the X Input
|
|
|
989 Method (XIM) framework, although support for MSIME (for MS Windows) is
|
|
|
990 planned, and IIIMF (Sun's Internet-Intranet Input Method Framework)
|
|
|
991 support is extremely desirable. XIM is enabled at build time by use of
|
|
|
992 the @samp{--with-xim} flag to @code{configure}. For use of XIM, see
|
|
|
993 your platform documentation. However, normally the input method you use
|
|
|
994 is specified via the @samp{LANG} and @samp{XMODIFIERS} environment
|
|
|
995 variables.
|
|
|
996
|
|
|
997 Of course, input skills are portable across most applications. However,
|
|
|
998 especially in modern GUI systems the habit of using bucky bits has
|
|
|
999 fallen into sad disuse, and many XIM systems are poorly configured for
|
|
|
1000 use with Emacs. For example, the kinput2 input manager (a separate
|
|
|
1001 process providing an interface between Japanese dictionary servers such
|
|
|
1002 as Canna and Wnn, and the application) tends to gobble up keystrokes
|
|
|
1003 generating Meta characters. This means that to edit while using an XIM
|
|
|
1004 input method, you must toggle the input method off every time you want
|
|
|
1005 to use @kbd{M-f}. Your mileage may vary.
|
|
|
1006
|
|
|
1007 @emph{Library interfaces} are most common for Japanese, although Wnn
|
|
|
1008 supports Chinese (traditional and simplified) and Korean. There are
|
|
|
1009 Chinese and Korean input servers available, but we do not know of any
|
|
|
1010 patches for XEmacs to use them directly. You can use them via
|
|
|
1011 IM-enabled terminals, by manipulating the terminal coding systems. We
|
|
|
1012 describe only the Japanese-oriented systems here. The advantage of
|
|
|
1013 these systems is that they are very powerful, and on platforms where
|
|
|
1014 they are available there is typically a wide range of applications that
|
|
|
1015 support them. Thus your input skills are portable across applications.
|
|
|
1016
|
|
|
1017 Mule provides built-in interfaces to the following input methods: Wnn4,
|
|
|
1018 Wnn6, Canna, and SJ3. These can be configured at build time. There are
|
|
|
1019 patches available (no URL, sorry) to support the SKK server, as well.
|
|
|
1020 Wnn and SJ3 use the @code{egg} user interface. The interface for Canna
|
|
|
1021 is specialized to Canna.
|
|
428
|
1022
|
|
|
1023 Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
|
|
1135
|
1024 University. It is a powerful and complex system. Wnn4 is free and Wnn6
|
|
|
1025 is not. Wnn uses grammatical hints and probability of word association,
|
|
|
1026 so in principle Wnn can be cleverer than other methods.
|
|
|
1027
|
|
|
1028 Canna, made by NEC, supports only Japanese. It is a simple and powerful
|
|
|
1029 system. Canna uses only grammar, but its grammar and dictionary are
|
|
|
1030 quite sophisticated. So for standard modern Japanese, Canna seems
|
|
|
1031 cleverer than Wnn4. In addition, the UNIX version of Canna is free (now
|
|
|
1032 there is a Microsoft Windows version).
|
|
|
1033
|
|
|
1034 SJ3, by Sony, supports only Japanese.
|
|
428
|
1035
|
|
|
1036 Egg consists of following parts:

1037
|
|

1038 @enumerate
|
|

1039 @item

|
428
|
1046 @end enumerate
|
|
|
1047
|
|
1135
|
1048 These input methods are modal. They have a raw (alphabet) mode, a
|
|
|
1049 phonetic input mode, and Kana-Kanji transfer mode. However there are
|
|
|
1050 mode-less input methods for Egg and Canna. @samp{boiled-egg} is a
|
|
|
1051 mode-less input method running on Egg. For Canna, @samp{canna.el} has a
|
|
|
1052 tiny boiled-egg-like command, @code{(canna-boil)}, and there are some
|
|
|
1053 boiled-egg-like utilities.

|

428

1060
|
|
1135
|
1061 MULE has evolved rapidly over the last few years, and the original third
|
|
|
1062 party patch (for GNU Emacs 19), GNU Emacs 20+, and XEmacs 20+ have quite
|
|
|
1063 different implementations. The APIs also vary although recent versions
|
|
|
1064 of XEmacs have tended to converge to the GNU Emacs standard.
|
|
|
1065
|
|
|
1066 MULE implementations are going to continue to evolve. Both GNU Emacs
|
|
|
1067 and XEmacs are working hard on Unicode support, which will involve new
|
|
|
1068 APIs and probably variations on old ones. For XEmacs 22, the old ISO
|
|
|
1069 2022-based system for recognizing encodings will be replaced by a much
|
|
|
1070 more flexible system, which should improve accuracy of automatic coding
|
|
|
1071 detections, but will also involve new APIs.

1182 @unnumberedsubsec Q1.3.9: How does XEmacs display Unicode?
|
|
|
1183
|
|
|
1184 Mule doesn't have a Unicode charset internally, so there's nothing to
|
|
|
1185 bind a Unicode registry to. It would not be straightforward to create,
|
|
|
1186 either, because Unicode is not ISO 2022-compatible. You'd have to
|
|
|
1187 translate it to multiple 96x96 pages.
|
|
|
1188
|
|
|
1189 This means that Mule-UCS uses ordinary national fonts for display. This
|
|
|
1190 is not really a problem, except for those languages that use the Unified
|
|
|
1191 Han characters. The problem here is that Mule-UCS maps from Unicode
|
|
|
1192 code points to national character sets in a deterministic way. By
|
|
|
1193 default, this means that Japanese fonts are tried first, then Chinese,
|
|
|
1194 then Korean. To change the priority ordering, use the command
|
|
|
1195 `un-define-change-charset-order'.
|
|
|
1196
|
|
|
1197 It also means you can't use Unicode fonts directly, at least not without
|
|
|
1198 extreme hackery. You can run -nw with (set-terminal-coding-system
|
|
|
1199 'utf-8) if you really want a Unicode font for some reason.
|
|
|
1200
|
|
|
1201 Real Unicode support will be introduced in XEmacs 22.0.

1205 @unnumberedsubsec Q1.4.1: What is an @file{init.el} or @file{.emacs} and is there a sample one?
|
|
|
1206
|
|
|
1207 The @file{init.el} or @file{.emacs} file is used to customize XEmacs to
|
|
|
1208 your tastes. Starting in 21.4, the preferred location for the init file
|
|
|
1209 is @file{~/.xemacs/init.el}; in previous versions, it was
|
|
|
1210 @file{~/.emacs}. 21.4 still accepts the old location, but the first
|
|
|
1211 time you run it, it will ask to migrate your file to the new location.
|
|
|
1212 If you answer yes, the file will be moved, and a "compatibility"
|
|
|
1213 @file{.emacs} file will be placed in the old location so that you can
|
|
|
1214 still run older versions of XEmacs, and versions of GNU Emacs, which
|
|
|
1215 expect the old location. The @file{.emacs} file present is just a stub
|
|
|
1216 that loads the real file in @file{~/.xemacs/init.el}.
|
|
|
1217
|
|
|
1218 No two init files are alike, nor are they expected to be alike, but
|
|
|
1219 that's the point. The XEmacs distribution contains an excellent starter
|
|
|
1220 example in the @file{etc/} directory called @file{sample.init.el}
|
|
|
1221 (starting in 21.4) or @file{sample.emacs} in older versions. Copy this
|
|
|
1222 file from there to @file{~/.xemacs/init.el} (starting in 21.4) or
|
|
|
1223 @file{~/.emacs} in older versions, where @samp{~} means your home
|
|
|
1224 directory, of course. Then edit it to suit.
|
|
|
1225
|
|
|
1226 You may bring the @file{sample.init.el} or @file{sample.emacs} file into
|
|
|
1227 an XEmacs buffer from the menubar. (The menu entry for it is always
|
|
|
1228 under the @samp{Help} menu, but its location under that has changed in
|
|
|
1229 various versions. Recently, look under the @samp{Samples} submenu.) To
|
|
|
1230 determine the location of the @file{etc/} directory type the command
|
|
428

1231 @kbd{C-h v data-directory @key{RET}}.

|
|
|
1263
|
|

1264 The following function does a little bit of everything useful. It does
|
|
|
1265 something with the prefix argument, it examines the text around the
|
|
|
1266 cursor, and it's interactive so it may be bound to a key. It inserts
|
|
|
1267 copies of the current word the cursor is sitting on at the cursor. If
|
|
|
1268 you give it a prefix argument: @kbd{C-u 3 M-x double-word} then it will
|
|
|
1269 insert 3 copies.
|
|
|
1270
|
|
|
1271 @lisp
|
|
|
1272 (defun double-word (count)
|
|
|
1273 "Insert a copy of the current word underneath the cursor"
|
|

1274 (interactive "*p")
|

1275 (let (here there string)
|

1276 (save-excursion

1279 (forward-word 1)

1282 (while (>= count 1)

|
|
1285 @end lisp
|
|
|
1286
|
|
|
1287 The best way to see what is going on here is to let XEmacs tell you.
|
|
|
1288 Put the code into an XEmacs buffer, and do a @kbd{C-h f} with the cursor
|
|
|
1289 sitting just to the right of the function you want explained. Eg. move
|
|
|
1290 the cursor to the SPACE between @code{interactive} and @samp{"*p"} and
|
|
|
1291 hit @kbd{C-h f} to see what the function @code{interactive} does. Doing
|
|
|
1292 this will tell you that the @code{*} requires a writable buffer, and
|
|
|
1293 @code{p} converts the prefix argument to a number, and
|
|
|
1294 @code{interactive} allows you to execute the command with @kbd{M-x}.

1308 @unnumberedsubsec Q1.4.6: What's the difference between a macro and a function?
|
|
|
1309
|
|
|
1310 Quoting from the Lisp Reference (a.k.a @dfn{Lispref}) Manual:
|
|
|
1311
|
|
|
1312 @dfn{Macros} enable you to define new control constructs and other
|
|
|
1313 language features. A macro is defined much like a function, but instead
|
|
|
1314 of telling how to compute a value, it tells how to compute another Lisp
|
|
|
1315 expression which will in turn compute the value. We call this
|
|
|
1316 expression the @dfn{expansion} of the macro.
|
|
|
1317
|
|
|
1318 Macros can do this because they operate on the unevaluated expressions
|
|
|
1319 for the arguments, not on the argument values as functions do. They can
|
|
|
1320 therefore construct an expansion containing these argument expressions
|
|
|
1321 or parts of them.
|
|
|
1322
|
|
|
1323 Do not confuse the two terms with @dfn{keyboard macros}, which are
|
|
|
1324 another matter, entirely. A keyboard macro is a key bound to several
|
|
|
1325 other keys. Refer to manual for details.

1384 How can I just try XEmacs without installing it?
|
|
428
|
1385
|
|
|
1386 XEmacs will run in place without requiring installation and copying of
|
|
|
1387 the Lisp directories, and without having to specify a special build-time
|
|
|
1388 flag. It's the copying of the Lisp directories that requires so much
|
|
|
1389 space. XEmacs is largely written in Lisp.
|
|
|
1390
|
|
|
1391 A good method is to make a shell alias for xemacs:
|
|
|
1392
|
|
|
1393 @example
|
|
|
1394 alias xemacs=/i/xemacs-20.2/src/xemacs
|
|
|
1395 @end example
|
|
|
1396
|
|
|
1397 (You will obviously use whatever directory you downloaded the source
|
|
|
1398 tree to instead of @file{/i/xemacs-20.2}).
|
|
|
1399
|
|
|
1400 This will let you run XEmacs without massive copying.

1404

1405 The space required by the installation directories can be

|
428
|
1406 reduced dramatically if desired. Gzip all the .el files. Remove all
|
|
442
|
1407 the packages you'll never want to use. Remove the TexInfo manuals.
|
|
428
|
1408 Remove the Info (and use just hardcopy versions of the manual). Remove
|
|
|
1409 most of the stuff in etc. Remove or gzip all the source code. Gzip or
|
|
|
1410 remove the C source code. Configure it so that copies are not made of
|
|
1138
|
1411 the support lisp.
|
|
428
|
1412
|
|
|
1413 These are all Emacs Lisp source code and bytecompiled object code. You
|
|
|
1414 may safely gzip everything named *.el here. You may remove any package
|
|
|
1415 you don't use. @emph{Nothing bad will happen if you delete a package
|
|
|
1416 that you do not use}. You must be sure you do not use it though, so be
|
|
|
1417 conservative at first.
|
|
|
1418
|
|
442
|
1419 Possible candidates for deletion include w3, games, hyperbole, mh-e,
|
|
|
1420 hm-html-menus, vm, viper, oobr, gnus, etc. Ask yourself, @emph{Do I
|
|
|
1421 ever want to use this package?} If the answer is no, then it is a
|
|
|
1422 candidate for removal.
|
|
428
|
1423
|
|
|
1424 First, gzip all the .el files. Then go about package by package and
|
|
|
1425 start gzipping the .elc files. Then run XEmacs and do whatever it is
|
|
|
1426 you normally do. If nothing bad happens, then delete the directory. Be
|
|
|
1427 conservative about deleting directories, and it would be handy to have a
|
|
442
|
1428 backup around in case you get too zealous.
|
|
428
|
1429
|
|
|
1430 @file{prim}, @file{modes}, @file{packages}, and @file{utils} are four
|
|
|
1431 directories you definitely do @strong{not} want to delete, although
|
|
|
1432 certain packages can be removed from them if you do not use them.
|
|
|
1433
|
|
442
|
1434 Online texinfo sources in the @file{info} can either be compressed them
|
|
|
1435 or remove them. In either case, @kbd{C-h i} (info mode) will no longer
|
|
|
1436 work.

1445

1446 You should only need to add some stuff to the configure command line.

1448 @samp{--with-sound=nas} if you don't want native sound support for some

1457 have a server running corresponding to the X server. The netaudio server

1458 has to be there when XEmacs starts. If the netaudio server goes away and

1651 That's correct [The SunOS 4.1.3 precompiled binaries don't do name
|
|
|
1652 lookup]. Since Sun figured that everyone used NIS to do name lookups
|
|
|
1653 (that DNS thing was apparently only a passing fad, right?), the stock

1654 SunOS 4.x systems don't have DNS-based name lookups in libc.
|

1655
|

1656 This is also why Netscape ships two binaries for SunOS 4.1.x.
|
|
|
1657
|
|
|
1658 The best solution is to compile it yourself; the configure script will
|
|

1659 check to see if you've put DNS in the shared libc and will then proceed

1660 to link against the DNS resolver library code.

1669 Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
|
|
|
1670 link gives you a bare-boned emacs (called temacs). temacs is then run,
|
|
|
1671 preloading some of the lisp files. The result is then dumped into a new
|
|
|
1672 executable, named xemacs, which will contain all of the preloaded lisp
|
|
|
1673 functions and data.
|
|
|
1674
|
|
|
1675 Now, during the dump itself, the executable (code+data+symbols) is
|
|
|
1676 written on disk using a special unexec() function. This function is
|
|
|
1677 obviously heavily system dependent. And on some systems, it leads to an
|
|
|
1678 executable which, although valid, cannot be stripped without damage. If
|
|
|
1679 memory serves, this is especially the case for AIX binaries. On other
|
|
462
|
1680 architectures it might work OK.
|
|
428
|
1681
|
|
|
1682 The Right Way to strip the emacs binary is to strip temacs prior to
|
|
|
1683 dumping xemacs. This will always work, although you can do that only if
|
|
|
1684 you install from sources (as temacs is @file{not} part of the binary
|
|
|
1685 kits).

|
|
|
1770
|
|
|
1771 The Cygwin binary distributed with the netinstaller uses an external DLL
|
|
|
1772 to handle XPM images (such as toolbar buttons). You may get an error like
|
|
|
1773
|
|
|
1774 This application has failed to start because cygXpm-noX4.dll was not found.
|
|
|
1775 Re-installing the application may fix this problem.
|
|
|
1776
|
|
|
1777 Andy Piper <andy@@xemacs.org> sez:
|
|
|
1778
|
|
|
1779 cygXpm-noX4 is part of the cygwin distribution under libraries or
|
|
|
1780 graphics, but is not installed by default. You need to run the
|
|
|
1781 cygwin setup again and select this package.
|
|
|
1782
|
|
|
1783 Ie, reinstalling XEmacs won't help because it is not part of the XEmacs
|
|
|
1784 distribution.

1788 @unnumberedsubsec Q2.1.1: Help! XEmacs just crashed on me!
|
|
|
1789
|
|
|
1790 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
|
1791 hard to auto-save all of your files before dying. (The main time that
|
|
|
1792 this will not happen is if the machine physically lost power or if you
|
|
|
1793 killed the XEmacs process using @code{kill -9}). The next time you try
|
|
|
1794 to edit those files, you will be informed that a more recent auto-save
|
|
|
1795 file exists. You can use @kbd{M-x recover-file} to retrieve the
|
|
|
1796 auto-saved version of the file.
|
|
|
1797
|
|
462
|
1798 You can use the command @kbd{M-x recover-session} after a crash to pick
|
|
|
1799 up where you left off.
|
|
428
|
1800
|
|
|
1801 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
1802 particular sequences of actions, that cause it to crash. If you can
|
|
|
1803 come up with a reproducible way of doing this (or even if you have a
|
|
|
1804 pretty good memory of exactly what you were doing at the time), the
|
|
|
1805 maintainers would be very interested in knowing about it. Post a
|
|
|
1806 message to comp.emacs.xemacs or send mail to @email{crashes@@xemacs.org}.
|
|
|
1807 Please note that the @samp{crashes} address is exclusively for crash
|
|
|
1808 reports.
|
|
|
1809
|
|
|
1810 If at all possible, include a stack backtrace of the core dump that was
|
|
|
1811 produced. This shows where exactly things went wrong, and makes it much
|
|
|
1812 easier to diagnose problems. To do this, you need to locate the core
|
|
|
1813 file (it's called @file{core}, and is usually sitting in the directory
|
|
|
1814 that you started XEmacs from, or your home directory if that other
|
|
|
1815 directory was not writable). Then, go to that directory and execute a
|
|
|
1816 command like:
|
|
|
1817
|
|
|
1818 @example
|
|
|
1819 gdb `which xemacs` core
|
|
|
1820 @end example
|
|
|
1821
|
|
|
1822 and then issue the command @samp{where} to get the stack backtrace. You
|
|
|
1823 might have to use @code{dbx} or some similar debugger in place of
|
|
|
1824 @code{gdb}. If you don't have any such debugger available, complain to
|
|
|
1825 your system administrator.
|
|
|
1826
|
|
|
1827 It's possible that a core file didn't get produced, in which case you're
|
|
|
1828 out of luck. Go complain to your system administrator and tell him not
|
|
593
|
1829 to disable core files by default. Also see @ref{Q2.1.15}, for tips and
|
|
428
|
1830 techniques for dealing with a debugger.

|
|

1900
|
|
|
1901 There are two causes of this problem. The first usually only strikes
|
|
|
1902 people using the prebuilt binaries. The culprit in both cases is the
|
|
|
1903 file @file{XKeysymDB}.
|

1904
|
|
|
1905 @itemize @bullet
|
|
|
1906 @item
|
|
|
1907 The binary cannot find the @file{XKeysymDB} file. The location is
|
|
|
1908 hardcoded at compile time so if the system the binary was built on puts
|
|
|
1909 it a different place than your system does, you have problems. To fix,
|
|
|
1910 set the environment variable @var{XKEYSYMDB} to the location of the
|
|
|
1911 @file{XKeysymDB} file on your system or to the location of the one
|
|
|
1912 included with XEmacs which should be at
|
|
|
1913 @iftex
|
|
|
1914 @*
|
|
|
1915 @end iftex

|
|
|
1918 @item
|
|
|
1919 The binary is finding the XKeysymDB but it is out-of-date on your system
|
|
|
1920 and does not contain the necessary lines. Either ask your system
|
|
|
1921 administrator to replace it with the one which comes with XEmacs (which
|
|
|
1922 is the stock R6 version and is backwards compatible) or set your

1929 How can I avoid the startup warnings about deducing proper fonts?
|
|
|
1930
|
|
|
1931 This is highly dependent on your installation, but try with the

1932 following font as your base font for XEmacs and see what it does:
|
|
|
1933
|
|
|
1934 @format
|
|
|
1935 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
|
1936 @end format
|
|
|
1937
|
|
|
1938 More precisely, do the following in your resource file:
|
|
|
1939
|
|
|
1940 @format
|
|
|
1941 Emacs.default.attributeFont: \
|
|
|
1942 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
|
1943 @end format
|
|
|
1944
|
|
|
1945 If you just don't want to see the @samp{*Warnings*} buffer at startup
|
|
|
1946 time, you can set this:
|
|
|
1947
|
|
|
1948 @lisp
|
|
|
1949 (setq display-warning-minimum-level 'error)
|
|

|
|

1951

2193 @unnumberedsubsec Q2.1.15: How to Debug an XEmacs problem with a debugger
|
|
|
2194
|
|
|
2195 If XEmacs does crash on you, one of the most productive things you can
|
|
|
2196 do to help get the bug fixed is to poke around a bit with the debugger.
|
|
|
2197 Here are some hints:
|
|
|
2198
|
|
|
2199 @itemize @bullet
|
|
|
2200 @item
|
|
|
2201 First of all, if the crash is at all reproducible, consider very
|
|
563
|
2202 strongly recompiling your XEmacs with debugging symbols and with no
|
|
|
2203 optimization (e.g. with GCC use the compiler flags @samp{-g -O0} --
|
|
|
2204 that's an "oh" followed by a zero), and with the configure options
|
|
|
2205 @samp{--debug=yes} and @samp{--error-checking=all}. This will make your
|
|
|
2206 XEmacs run somewhat slower but make it a lot more likely to catch the
|
|
|
2207 problem earlier (closer to its source), and a lot easier to determine
|
|
|
2208 what's going on with a debugger.
|
|
428
|
2209
|
|
|
2210 @item
|
|
|
2211 If you're able to run XEmacs under a debugger and reproduce the crash
|
|
|
2212 (if it's inconvenient to do this because XEmacs is already running or is
|
|
|
2213 running in batch mode as part of a bunch of scripts, consider attaching
|
|
|
2214 to the existing process with your debugger; most debuggers let you do
|
|
|
2215 this by substituting the process ID for the core file when you invoke
|
|
|
2216 the debugger from the command line, or by using the @code{attach}
|
|
|
2217 command or something similar), here are some things you can do:
|
|
|
2218
|
|
|
2219 @item
|
|
|
2220 If XEmacs is hitting an assertion failure, put a breakpoint on
|
|
|
2221 @code{assert_failed()}.
|
|
|
2222
|
|
|
2223 @item
|
|
|
2224 If XEmacs is hitting some weird Lisp error that's causing it to crash
|
|
|
2225 (e.g. during startup), put a breakpoint on @code{signal_1()}---this is
|
|
|
2226 declared static in eval.c.
|
|
|
2227
|
|
|
2228 @item
|
|
563
|
2229 If XEmacs is outputting lots of X errors, put a breakpoint on
|
|
|
2230 @code{x_error_handler()}; that will tell you which call is causing them.
|
|
|
2231
|
|
|
2232 @item
|
|
428
|
2233 Internally, you will probably see lots of variables that hold objects of
|
|
|
2234 type @code{Lisp_Object}. These are exactly what they appear to be,
|
|
|
2235 i.e. references to Lisp objects. Printing them out with the debugger
|
|
|
2236 probably won't be too useful---you'll likely just see a number. To
|
|
|
2237 decode them, do this:
|
|
|
2238
|
|
|
2239 @example
|
|
|
2240 call debug_print (OBJECT)
|
|
|
2241 @end example
|
|
|
2242
|
|
|
2243 where @var{OBJECT} is whatever you want to decode (it can be a variable,
|
|
|
2244 a function call, etc.). This will print out a readable representation
|
|
|
2245 on the TTY from which the xemacs process was invoked.
|
|
|
2246
|
|
|
2247 @item
|
|
|
2248 If you want to get a Lisp backtrace showing the Lisp call
|
|
|
2249 stack, do this:
|
|
|
2250
|
|
|
2251 @example
|
|
|
2252 call debug_backtrace ()
|
|
|
2253 @end example
|
|
|
2254
|
|
|
2255 @item
|
|
|
2256 Using @code{debug_print} and @code{debug_backtrace} has two
|
|
|
2257 disadvantages - it can only be used with a running xemacs process, and
|
|
|
2258 it cannot display the internal C structure of a Lisp Object. Even if
|
|
|
2259 all you've got is a core dump, all is not lost.
|
|
|
2260
|
|
|
2261 If you're using GDB, there are some macros in the file
|
|
438
|
2262 @file{src/.gdbinit} in the XEmacs source distribution that should make
|
|
|
2263 it easier for you to decode Lisp objects. This file is automatically
|
|
|
2264 read by gdb if gdb is run in the directory where xemacs was built, and
|
|
|
2265 contains these useful macros to inspect the state of xemacs:

2313 If you're using a debugger to get a C stack backtrace and you're seeing
|
|
|
2314 stack traces with some of the innermost frames mangled, it may be due to
|
|
|
2315 dynamic linking. (This happens especially under Linux.) Consider
|
|
|
2316 reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
|
|
|
2317 Linux), stack backtraces of core dumps will have the frame where the
|
|
|
2318 fatal signal occurred mangled; if you can obtain a stack trace while
|
|
|
2319 running the XEmacs process under a debugger, the stack trace should be
|
|
|
2320 clean.

2326 If you're using a debugger to get a C stack backtrace and you're

|
|
2327 getting a completely mangled and bogus stack trace, it's probably due to
|
|
|
2328 one of the following:

2332 Your executable has been stripped. Bad news. Tell your sysadmin not to

|
|
|
2334 space, and makes debugging much much harder.
|
|
|
2335
|
|
|
2336 @item
|
|
|
2337 Your stack is getting trashed. Debugging this is hard; you have to do a
|
|
|
2338 binary-search type of narrowing down where the crash occurs, until you
|
|
|
2339 figure out exactly which line is causing the problem. Of course, this
|
|
|
2340 only works if the bug is highly reproducible.
|
|
|
2341

|
2342 @item
|
|
|
2343 If your stack trace has exactly one frame in it, with address 0x0, this
|
|
|
2344 could simply mean that XEmacs attempted to execute code at that address,
|
|
|
2345 e.g. through jumping to a null function pointer. Unfortunately, under
|
|
|
2346 those circumstances, GDB under Linux doesn't know how to get a stack
|
|
|
2347 trace. (Yes, this is the third Linux-related problem I've mentioned. I
|
|
|
2348 have no idea why GDB under Linux is so bogus. Complain to the GDB
|
|
|
2349 authors, or to comp.os.linux.development.system). Again, you'll have to
|
|

|

2420
|
|

2421 When using one of the prebuilt binaries many users have observed that
|
|
|
2422 XEmacs uses the timezone under which it was built, but not the timezone
|
|
|
2423 under which it is running. The solution is to add:
|
|
|
2424
|
|
|
2425 @lisp
|
|
|
2426 (set-time-zone-rule "MET")
|

|
462
|
2429 to your @file{init.el}/@file{.emacs} or the @file{site-start.el} file if
|
|
|
2430 you can. Replace @code{MET} with your local timezone.

2452 Two things you can do:
|
|
|
2453
|
|
|
2454 1) C level:
|
|
|
2455
|
|
|
2456 When you see it going mad like this, you might want to use gdb from an
|
|
|
2457 'xterm' to attach to the running process and get a stack trace. To do
|
|
|
2458 this just run:
|
|
|
2459
|
|
|
2460 @example
|
|
|
2461 gdb /path/to/xemacs/xemacs ####
|
|
|
2462 @end example
|
|
|
2463
|
|
|
2464 Where @code{####} is the process id of your xemacs, instead of
|
|
|
2465 specifying the core. When gdb attaches, the xemacs will stop [1] and
|
|
|
2466 you can type `where' in gdb to get a stack trace as usual. To get
|
|
|
2467 things moving again, you can just type `quit' in gdb. It'll tell you
|
|
|
2468 the program is running and ask if you want to quit anyways. Say 'y' and
|
|
|
2469 it'll quit and have your emacs continue from where it was at.
|
|
|
2470
|
|
|
2471 2) Lisp level:
|
|
|
2472
|
|
|
2473 Turn on debug-on-quit early on. When you think things are going slow
|
|
|
2474 hit C-g and it may pop you in the debugger so you can see what routine
|
|
|
2475 is running. Press `c' to get going again.
|
|
|
2476
|
|
|
2477 debug-on-quit doesn't work if something's turned on inhibit-quit or in
|
|
|
2478 some other strange cases.

2775 Starting with XEmacs 20.2 there is new system 'Customize' for customizing

|
2776 XEmacs options.
|
|
|
2777
|
|
|
2778 You can access @code{Customize} from the @code{Options} menu

2779 or invoking one of customize commands by typing eg.

2780 @kbd{M-x customize}, @kbd{M-x customize-face},

2781 @kbd{M-x customize-variable} or @kbd{M-x customize-apropos}.
|

2782
|

2856 @unnumberedsubsec Q3.1.7: @samp{xemacs -name junk} doesn't work?
|
|
|
2857
|
|
|
2858 When I run @samp{xterm -name junk}, I get an xterm whose class name
|
|
|
2859 according to xprop, is @samp{junk}. This is the way it's supposed to
|
|
|
2860 work, I think. When I run @samp{xemacs -name junk} the class name is
|
|
|
2861 not set to @samp{junk}. It's still @samp{emacs}. What does
|
|
|
2862 @samp{xemacs -name} really do? The reason I ask is that my window
|
|
|
2863 manager (fvwm) will make a window sticky and I use XEmacs to read my
|
|
|
2864 mail. I want that XEmacs window to be sticky, without having to use the
|
|
|
2865 window manager's function to set the window sticky. What gives?
|
|
|
2866
|
|
|
2867 @samp{xemacs -name} sets the application name for the program (that is,
|
|
|
2868 the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
|
|
|
2869 is the same as making a copy of the executable with that new name. The
|
|
|
2870 @code{WM_CLASS} property on each frame is set to the frame-name, and the
|
|
|
2871 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
2872 created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
|
|
|
2873 @code{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
2874 widget would be:
|
|
|
2875
|
|
|
2876 @example
|
|
|
2877 Name: FOO .shell .container .BAR
|
|
|
2878 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2879 @end example
|
|
|
2880
|
|
|
2881 instead of the default
|
|
|
2882
|
|
|
2883 @example
|
|
|
2884 Name: xemacs.shell .container .emacs
|
|
|
2885 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2886 @end example
|
|
|
2887
|
|
|
2888
|
|
|
2889 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
2890 application-name instead of the frame-name, but I think that's less
|
|
|
2891 flexible, since it does not give you the ability to have multiple frames
|
|
|
2892 with different WM_CLASS properties. Another possibility would be for
|
|
|
2893 the default frame name to come from the application name instead of
|
|
|
2894 simply being @samp{emacs}. However, at this point, making that change
|
|
|
2895 would be troublesome: it would mean that many users would have to make
|
|
|
2896 yet another change to their resource files (since the default frame name
|
|
|
2897 would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
|
|
|
2898 the executable happened to be named), so we'd rather avoid it.
|
|
|
2899
|
|
|
2900 To make a frame with a particular name use:
|
|
|
2901
|
|
|
2902 @lisp
|
|
|
2903 (make-frame '((name . "the-name")))

2997 @unnumberedsubsec Q3.2.4: How can I limit color map usage?
|
|
|
2998
|
|
|
2999 I'm using Netscape (or another color grabber like XEmacs);
|
|
462
|
3000 is there any way to limit the number of available colors in the color map?
|
|
|
3001
|
|
|
3002 Answer: No, but you can start Netscape before XEmacs, and it will use
|
|
|
3003 the closest available color if the colormap is full. You can also limit
|
|
|
3004 the number of colors Netscape uses, using the flags -mono, -ncols <#> or
|
|
|
3005 -install (for mono, limiting to <#> colors, or for using a private color
|
|
|
3006 map).
|
|
428
|
3007
|
|
|
3008 If you have the money, another solution would be to use a truecolor or
|
|
|
3009 direct color video.

|
|
|
3013
|
|
|
3014 XEmacs tries to automatically determine whether your tty supports color,
|

|
3015 but sometimes guesses wrong. In that case, you can make XEmacs Do The

3029 There are several ways to do it. For example, you could specify a
|
|

3030 default pixmap image to use in your @file{~/.Xresources}, e.g.,
|
|
|
3031
|

|

3036
|
|
|
3037
|
|
|
3038 and then reload ~/.Xresources and restart XEmacs. Alternatively,
|
|
|
3039 since each face can have its own pixmap background, a better way
|
|
|
3040 would be to set a face's pixmap within your XEmacs init file, e.g.,
|
|
|
3041
|
|
|
3042 @lisp
|
|
|
3043 (set-face-background-pixmap 'default "/path/to/image.xpm")

3047 and so on. You can also do this interactively via @kbd{M-x edit-faces}.

3055 If you're using a Mule-enabled XEmacs, then display is automatic. If
|
|
|
3056 you're not seeing the characters you expect, either (1) you don't have
|
|
|
3057 appropriate fonts available or (2) XEmacs did not correctly detect the
|
|
|
3058 coding system (@pxref{Recognize Coding, , , xemacs}). In case (1),
|
|
|
3059 install fonts as is customary for your platform. In case (2), you

3060 need to tell XEmacs explicitly what coding systems you're using.

|

3172 (add-hook 'lisp-mode-hook

|
|
|
3175 @end lisp
|
|

3176
|
|
|
3177 Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline
|
|
462
|
3178 colors change from the default set in your @file{init.el}/@file{.emacs}.
|
|
|
3179 The change will only be made in the buffer you just entered (which
|
|
|
3180 contains the Lisp file you are editing) and will not affect the modeline
|
|
|
3181 colors anywhere else.

3230 @unnumberedsubsec Q3.5.1: How can I bind complex functions (or macros) to keys?
|
|
|
3231
|
|
|
3232 As an example, say you want the @kbd{paste} key on a Sun keyboard to
|
|
|
3233 insert the current Primary X selection at point. You can accomplish this
|
|
|
3234 with:
|
|
|
3235
|
|
|
3236 @lisp
|
|
|
3237 (define-key global-map [f18] 'x-insert-selection)
|
|
|
3238 @end lisp
|
|
|
3239
|
|
|
3240 However, this only works if there is a current X selection (the
|
|
|
3241 selection will be highlighted). The functionality I like is for the
|
|
|
3242 @kbd{paste} key to insert the current X selection if there is one,
|
|
|
3243 otherwise insert the contents of the clipboard. To do this you need to
|
|
|
3244 pass arguments to @code{x-insert-selection}. This is done by wrapping
|
|
|
3245 the call in a 'lambda form:
|
|
|
3246
|
|
|
3247 @lisp
|
|
|
3248 (global-set-key [f18]
|
|
|
3249 (lambda () (interactive) (x-insert-selection t nil)))
|
|
|
3250 @end lisp
|
|
|
3251
|
|
|
3252 This binds the f18 key to a @dfn{generic} functional object. The
|
|
|
3253 interactive spec is required because only interactive functions can be
|
|
|
3254 bound to keys.
|
|
|
3255
|
|
|
3256 For the FAQ example you could use:
|
|
|
3257
|
|
|
3258 @lisp
|
|
|
3259 (global-set-key [(control ?.)]
|
|
|
3260 (lambda () (interactive) (scroll-up 1)))
|
|
440
|
3261 (global-set-key [(control ?;)]
|
|
|
3262 (lambda () (interactive) (scroll-up -1)))
|
|
428
|
3263 @end lisp
|
|
|
3264
|
|
|
3265 This is fine if you only need a few functions within the lambda body.
|
|
|
3266 If you're doing more it's cleaner to define a separate function as in
|
|
|
3267 question 3.5.3 (@pxref{Q3.5.3}).

3299 The key point is that you can only bind simple functions to keys; you
|
|
|
3300 can not bind a key to a function that you're also passing arguments to.

3304 @unnumberedsubsec Q3.5.4: Globally binding @kbd{Delete}?
|
|
|
3305
|
|
|
3306 I cannot manage to globally bind my @kbd{Delete} key to something other
|
|
|
3307 than the default. How does one do this?
|
|
|
3308
|
|
462
|
3309 Answer: The problem is that many modes explicitly bind @kbd{Delete}. To
|
|
|
3310 get around this, try the following:
|
|
|
3311
|
|
428
|
3312 @lisp
|
|
|
3313 (defun foo ()
|

|
|
|
3316

|
462

3317 (define-key key-translation-map 'delete 'redirected-delete)

3318 (global-set-key 'redirected-delete 'foo)

3327 default half page jump? I tend it to find it disorienting.
|
|

3328
|
|
|
3329 Try this:

3344 @end lisp
|
|

3345
|
|
|
3346 The following will also work but will affect more than just the cursor
|
|

3347 keys (i.e. @kbd{C-n} and @kbd{C-p}):

3400 It depends upon your X server.
|
|
|
3401
|
|
|
3402 Generally, the simplest way is to define a key as Multi_key with
|
|
|
3403 xmodmap, e.g.
|
|
|
3404 @c hey, show some respect, willya -- there's xkeycaps, isn't there? --
|
|
|
3405 @c chr ;)
|
|
|
3406 @example
|
|
440
|
3407 xmodmap -e 'keycode 0xff20 = Multi_key'
|
|
428
|
3408 @end example
|
|
|
3409
|
|
|
3410 You will need to pick an appropriate keycode. Use xev to find out the
|
|
|
3411 keycodes for each key.
|
|
|
3412
|
|
|
3413 [NB: On a `Windows' keyboard, recent versions of XFree86 automatically
|
|
|
3414 define the right `Windows' key as Multi_key'.]
|
|
|
3415
|
|
|
3416 Once you have Multi_key defined, you can use e.g.
|
|
|
3417 @example
|
|
440
|
3418 Multi a ' => á
|
|
|
3419 Multi e " => ë
|
|
|
3420 Multi c , => ç
|
|
428
|
3421 @end example
|
|
|
3422
|
|
|
3423 etc.
|
|
|
3424
|
|
|
3425 Also, recent versions of XFree86 define various AltGr-<key>
|
|
|
3426 combinations as dead keys, i.e.
|
|
|
3427 @example
|
|
440
|
3428 AltGr [ => dead_diaeresis
|
|
|
3429 AltGr ] => dead_tilde
|
|
|
3430 AltGr ; => dead_acute
|
|
428
|
3431 @end example
|
|
|
3432 etc.
|
|

3433
|

|
|
|
3447
|

3448 With XEmacs-20.2 use the @code{delbs} package:

3449
|

3450 @lisp
|
|
|
3451 (require 'delbs)
|
|

|
|
|
3453
|
|
|
3454 This will give you the functions @code{delbs-enable-delete-forward} to
|
|
|
3455 set things up, and @code{delbs-disable-delete-forward} to revert to
|
|
|
3456 ``normal'' behavior. Note that @code{delbackspace} package is obsolete.
|
|
|
3457
|
|
|
3458 Starting with XEmacs-20.3 better solution is to set variable
|
|
|
3459 @code{delete-key-deletes-forward} to t. You can also change this with
|
|
|
3460 Customize. Select from the @code{Options} menu

3461 @code{Advanced (Customize)->Emacs->Editing->Basics->Delete Key Deletes Forward} or

|
|
|
3619
|
|
|
3620 We don't know. It's a bug. There does seem to be a work-around,
|
|
|
3621 however. Try running xclipboard first. It appears to fix the problem
|
|
|
3622 even if you exit it. (This should be mostly fixed in 19.13, but we
|
|
|
3623 haven't yet verified that).

3627

3628 By default XEmacs pastes X selections where the mouse pointer is. How

3629 do I disable this?
|

|
3630
|
|

3631 Examine the function @code{mouse-yank}, by typing @kbd{C-h f mouse-yank
|

3632 @key{RET}}.
|
|
|
3633
|
|
462

3634 To get XEmacs to paste at the text cursor, add this your @file{init.el}/@file{.emacs}:

|
|
|
3647
|
|
|
3648 Just select the region normally, then use the rectangle commands (e.g.
|
|
|
3649 @code{kill-rectangle} on it. The region does not highlight as a
|
|
|
3650 rectangle, but the commands work just fine.
|
|
|
3651
|
|
|
3652 To actually sweep out rectangular regions with the mouse you can use
|
|
|
3653 @code{mouse-track-do-rectangle} which is assigned to @kbd{M-button1}.
|
|
|
3654 Then use rectangle commands.

|

3786
|
|

3791 Or select from the @code{Options} menu @code{Frame Appearance->Scrollbars}.
|
|
|
3792 Remember to save options.
|
|
|
3793
|
|

3794 To turn the scrollbar off on a per-frame basis, use the following

3795 function:
|
|

3796

3800
|
|
|
3801 You can actually turn the scrollbars on at any level you want by
|
|
|
3802 substituting for (selected-frame) in the above command. For example, to
|
|
|
3803 turn the scrollbars off only in a single buffer:
|
|

3836
|
|
|
3837 When I move the scrollbar in an XEmacs window, it moves the point as
|
|
|
3838 well, which should not be the default behavior. Is this a bug or a
|
|
|
3839 feature? Can I disable it?
|
|
|
3840
|
|
|
3841 The current behavior is a feature, not a bug. Point remains at the same
|
|
|
3842 buffer position as long as that position does not scroll off the screen.
|
|
|
3843 In that event, point will end up in either the upper-left or lower-left
|
|
|
3844 hand corner.
|

|
|
|
3853
|
|
|
3854 More precisely: If @code{truncate-lines} is nil, horizontal scrollbars
|
|
|
3855 will never appear. Otherwise, they will appear only if the value of
|
|
|
3856 @code{scrollbar-height} for that buffer/window/etc. is non-zero. If you

|
|
|
3890 the typed text replaces the selected text, similar to Motif.
|
|
|
3891
|
|
|
3892 You want to use something called @dfn{pending delete}. Pending delete
|
|
|
3893 is what happens when you select a region (with the mouse or keyboard)
|
|
|
3894 and you press a key to replace the selected region by the key you typed.
|
|
|
3895 Usually backspace kills the selected region.
|
|
|
3896
|
|
462

3899 @lisp

3975 @unnumberedsubsec Q3.10.6: Why is killing so slow?
|
|
|
3976
|
|
|
3977 This actually is an X Windows question, although you'll notice it with
|
|
|
3978 keyboard operations as well as while using the GUI. Basically, there
|
|
|
3979 are four ways to communicate interprogram via the X server:
|
|
|
3980
|
|
|
3981 @table @strong
|
|
|
3982 @item Primary selection
|
|
|
3983 a transient selection that gets replaced every time a new selection is made
|
|
|
3984
|
|
|
3985 @item Secondary selection
|
|
|
3986 for "exchanging" with the primary selection
|
|
|
3987
|
|
|
3988 @item Cut buffers
|
|
|
3989 a clipboard internal to the X server (deprecated)
|
|
|
3990
|
|
|
3991 @item Clipboard selection
|
|
|
3992 a selection with a notification protocol that allows a separate app to
|
|
|
3993 manage the clipboard
|
|
|
3994 @end table
|
|
|
3995
|
|
|
3996 The cut buffers are deprecated because managing them is even more
|
|
|
3997 inefficient than the clipboard notification protocol. The primary
|
|
|
3998 selection works fine for many users and applications, but is not very
|
|
|
3999 robust under intensive or sophisticated use.
|
|
|
4000
|
|
|
4001 In Motif and MS Windows, a clipboard has become the primary means for
|
|
|
4002 managing cut and paste. These means that "modern" applications tend to
|
|
|
4003 be oriented toward a true clipboard, rather than the primary selection.
|
|
|
4004 (On Windows, there is nothing equivalent to the primary selection.)
|
|
|
4005 It's not that XEmacs doesn't support the simple primary selection
|
|
|
4006 method, it's that more and more other applications don't.
|
|
|
4007
|
|
|
4008 So the slowdown occurs because XEmacs now engages in the clipboard
|
|
|
4009 notification protocol on @emph{every} kill. This is especially slow on
|
|
|
4010 Motif.
|
|
|
4011
|
|
|
4012 With most people running most clients and server on the same host, and
|
|
|
4013 many of the rest working over very fast communication, you may expect
|
|
|
4014 that the situation is not going to improve.
|
|
|
4015
|
|
|
4016 There are a number of workarounds. The most effective is to use a
|
|
|
4017 special command to do selection ownership only when you intend to paste
|
|
|
4018 to another application. Useful commands are @code{kill-primary-selection}
|
|
|
4019 and @code{copy-primary-selection}. These work only on text selected
|
|
|
4020 with the mouse (probably; experiment), and are bound by default to the
|
|
|
4021 @kbd{Cut} and @kbd{Copy}, respectively, buttons on the toolbar.
|
|
|
4022 @code{copy-primary-selection} is also bound to @kbd{C-Insert}. You can
|
|
|
4023 yank the clipboard contents with @code{yank-primary-selection}, bound to
|
|
|
4024 the @kbd{Paste} toolbar button and @kbd{Sh-Insert}.
|
|
|
4025
|
|
|
4026 If you are communicating by cut and paste with applications that use the
|
|
|
4027 primary selection, then you can customize
|
|
|
4028 @code{interprogram-cut-function} to @code{nil}, restoring the XEmacs
|
|
|
4029 version 20 behavior. How can you tell if a program will support this?
|
|
|
4030 Motifly-correct programs require the clipboard; you lose. For others,
|
|
|
4031 only by trying it. You also need to customize the complementary
|
|
|
4032 @code{interprogram-paste-function} to @code{nil}. (Otherwise
|
|
|
4033 XEmacs-to-XEmacs pastes will not work correctly.)
|
|
|
4034
|
|
|
4035 You may get some relief on Motif by setting
|
|
|
4036 @code{x-selection-strict-motif-ownership} to nil, but this means you will
|
|
|
4037 only intermittently be able to paste XEmacs kills to Motif applications.
|
|
|
4038
|
|
|
4039 Thanks to Jeff Mincy and Glynn Clements for corrections.

4226 to do this. You control which one is used by defining, or not defining,

|
|
|
4236 suitable group such as @samp{mail}. You can use these commands (as
|
|
|
4237 root):
|
|
|
4238
|
|
|
4239 @example
|
|
|
4240 chgrp mail movemail
|
|
|
4241 chmod 2755 movemail
|
|
|
4242 @end example
|
|
|
4243
|
|
|
4244 If your system uses the lock file protocol, and fascist restrictions
|
|
|
4245 prevent ordinary users from writing the lock files in
|
|
|
4246 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a
|
|
|
4247 suitable group such as @code{mail}. To do this, use the following
|
|
|
4248 commands (as root) after doing the make install.
|
|
|
4249
|
|
|
4250 @example
|
|
|
4251 chgrp mail movemail
|
|
|
4252 chmod 2755 movemail
|
|
|
4253 @end example
|
|
|
4254
|
|
|
4255 Installation normally copies movemail from the build directory to an
|
|
|
4256 installation directory which is usually under @file{/usr/local/lib}.
|
|
|
4257 The installed copy of @code{movemail} is usually in the directory
|
|
|
4258 @file{/usr/local/lib/emacs/VERSION/TARGET}. You must change the group
|
|
|
4259 and mode of the installed copy; changing the group and mode of the build
|
|
|
4260 directory copy is ineffective.

4378

4379 @lisp

4380 (defun toolbar-news ()

4437

4438 TM stands for @dfn{Tools for MIME} and not Tiny MIME. TM integrates
|
|
|
4439 with all major XEmacs packages like Gnus (all flavors), VM, MH-E, and
|
|
|
4440 mailcrypt. It provides totally transparent and trouble-free MIME
|
|
|
4441 support. When appropriate a message will be decoded in place in an
|
|
|
4442 XEmacs buffer.
|
|
|
4443

4444 TM now comes as a package with XEmacs 19.16 and XEmacs 20.2.

4551 EOS stands for "Era on SPARCworks", but I don't know what Era stands
|
|
|
4552 for.
|
|
|
4553
|
|
|
4554 EOS is the integration of XEmacs with the SPARCworks debugger. It
|
|
|
4555 allows one to use an XEmacs frame to view code (complete with
|
|
|
4556 fontification, etc.), set breakpoints, print variables, etc., while
|
|
|
4557 using the SPARCworks debugger. It works very well and I use it all the
|
|
|
4558 time.

|
4638 @uref{http://sourceforge.net/projects/infodock/, InfoDock} is an
|
|
|
4639 integrated productivity toolset, mainly aimed at technical people,
|
|
|
4640 hosted at SourceForge.
|
|
428
|
4641
|
|
|
4642 InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
|
|
|
4643 the power of Emacs, but with an easier to use and more comprehensive
|
|
|
4644 menu-based user interface. The bottom portion of this text describes
|
|
|
4645 how it differs from XEmacs and GNU Emacs from the Free Software
|
|
|
4646 Foundation.
|
|
|
4647
|
|
|
4648 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
4649 environment. Although InfoDock is customizable, it is not intended for
|
|
|
4650 people who like basic versions of Emacs which need to be customized
|
|
|
4651 extensively for local use; standard Emacs distributions are better for
|
|
|
4652 such uses. InfoDock is for those people who want a complete,
|
|
|
4653 pre-customized environment in one package, which they need not touch
|
|
|
4654 more than once or twice a year to update to new revisions.
|
|
|
4655
|
|
|
4656 InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
|
|
|
4657 and Intel Linux systems. It is intended for use on a color display,
|
|
|
4658 although most features will work on monochrome monitors. Simply unpack
|
|
|
4659 InfoDock according to the instructions in the ID-INSTALL file and you
|
|
|
4660 are ready to run.
|
|
|
4661
|
|
|
4662 The InfoDock Manual is concise, yet sufficient as a user guide for users
|
|
|
4663 who have never used an Emacs-type editor before. For users who are
|
|
|
4664 already familiar with Emacs, it supplements the information in the GNU
|
|
|
4665 Emacs Manual.
|
|
|
4666
|
|
|
4667 InfoDock menus are much more extensive and more mature than standard
|
|
|
4668 Emacs menus. Each menu offers a @samp{Manual} item which displays
|
|
|
4669 documentation associated with the menu's functions.
|
|
|
4670
|
|
|
4671 @noindent
|
|
|
4672 Four types of menubars are provided:
|
|
|
4673 @enumerate
|
|
|
4674 @item
|
|
|
4675 An extensive menubar providing access to global InfoDock commands.
|
|
|
4676 @item
|
|
|
4677 Mode-specific menubars tailored to the current major mode.
|
|
|
4678 @item
|
|
|
4679 A simple menubar for basic editing to help novices get started with InfoDock.
|
|
|
4680 @item
|
|
|
4681 The standard XEmacs menubar.
|
|
|
4682 @end enumerate
|
|
|
4683
|
|
|
4684 Most modes also include mode-specific popup menus. Additionally, region and
|
|
|
4685 rectangle popup menus are included.
|
|
|
4686
|
|
|
4687 @samp{Hyperbole}, the everyday information manager, is a core part of
|
|
|
4688 InfoDock. This provides context-sensitive mouse keys, a rolodex-type
|
|
|
4689 contact manager, programmable hypertext buttons, and an autonumbered
|
|
|
4690 outliner with embedded hyperlink anchors.
|
|
|
4691
|
|
|
4692 The @samp{OO-Browser}, a multi-language object-oriented code browser, is a
|
|
|
4693 standard part of InfoDock.
|
|
|
4694
|
|
|
4695 InfoDock saves a more extensive set of user options than other Emacs
|
|
|
4696 versions.
|
|
|
4697
|
|
|
4698 InfoDock inserts a useful file header in many file types, showing the
|
|
|
4699 author, summary, and last modification time of each file. A summary
|
|
|
4700 program can then be used to summarize all of the files in a directory,
|
|
|
4701 for easy MANIFEST file creation.
|
|
|
4702
|
|
|
4703 Your working set of buffers is automatically saved and restored (if you
|
|
|
4704 answer yes to a prompt) between InfoDock sessions.
|
|
|
4705
|
|
|
4706 Refined color choices for code highlighting are provided for both dark and
|
|
|
4707 light background display frames.
|
|
|
4708
|
|
|
4709 The @kbd{C-z} key prefix performs frame-based commands which parallel the
|
|
|
4710 @kbd{C-x} key prefix for window-based commands.
|
|
|
4711
|
|
|
4712 The Smart Menu system is included for producing command menus on dumb
|
|
|
4713 terminals.
|
|
|
4714
|
|
|
4715 Lisp libraries are better categorized according to function.
|
|
|
4716
|
|
|
4717 Extensions and improvements to many areas of Emacs are included, such as:
|
|
|
4718 paragraph filling, mail reading with Rmail, shell handling, outlining, code
|
|
|
4719 highlighting and browsing, and man page browsing.
|
|
|

4837 AUC TeX works fine on both stock Emacs and XEmacs has been doing so for

4838 a very very long time. This is mostly due to the work of

|
|
|
4862
|
|
|
4863 The reason for an Emacs package not to be included in XEmacs is
|
|
|
4864 usually one or more of the following:
|
|
|
4865
|
|
|
4866 @enumerate
|
|
|
4867 @item
|
|
|
4868 The package has not been ported to XEmacs. This will typically happen
|
|
|
4869 when it uses GNU-Emacs-specific features, which make it fail under
|
|
|
4870 XEmacs.
|
|
|
4871
|
|
|
4872 Porting a package to XEmacs can range from a trivial amount of change to
|
|
|
4873 a partial or full rewrite. Fortunately, the authors of modern packages
|
|
|
4874 usually choose to support both Emacsen themselves.

4877 The package has been decided not to be appropriate for XEmacs. It may
|
|
|
4878 have an equivalent or better replacement within XEmacs, in which case
|
|
|
4879 the developers may choose not to burden themselves with supporting an
|
|
|
4880 additional package.
|
|
|
4881
|
|
|
4882 Each package bundled with XEmacs means more work for the maintainers,
|
|
|
4883 whether they want it or not. If you are ready to take over the
|
|
|
4884 maintenance responsibilities for the package you port, be sure to say
|
|
440
|
4885 so---we will more likely include it.

4888 The package simply hasn't been noted by the XEmacs development. If
|
|
|
4889 that's the case, the messages like yours are very useful for attracting
|
|
|
4890 our attention.

4893 The package was noted by the developers, but they simply haven't yet
|
|
|
4894 gotten around to including/porting it. Wait for the next release or,
|
|
|
4895 even better, offer your help. It will be gladly accepted and
|
|
|
4896 appreciated.

|
|
|
4908
|
|
|
4909 Yes. Of course XEmacs can use any network file system (such as NFS or
|
|
|
4910 Windows file sharing) you have available, and includes some
|
|
|
4911 optimizations and safety features appropriate to those environments.
|
|
|
4912
|
|
|
4913 It is also possible to transparently edit files via FTP, ssh, or rsh. That
|
|
|
4914 is, XEmacs makes a local copy using the transport in the background, and
|
|
|
4915 automatically refreshes the remote original from that copy when you save
|
|
|
4916 it. XEmacs also is capable of doing file system manipulations like
|
|
|
4917 creating and removing directories and files. The FTP interface is
|
|
|
4918 provided by the standard @samp{efs} package @ref{Top, EFS, , efs}. The
|
|
|
4919 ssh/rsh interface is provided by the optional @samp{tramp} package

|
|
|
4989
|
|
|
4990 For most modes, font-lock is already set up and just needs to be turned
|
|
462
|
4991 on. This can be done by adding the line:
|
|
428
|
4992
|
|
|
4993 @lisp
|
|
462
|
4994 (require 'font-lock)

428

4995 @end lisp
|
|
|
4996
|
|
462
|
4997 to your @file{init.el}/@file{.emacs}. (You can turn it on for the
|
|
|
4998 current buffer and session only by @kbd{M-x font-lock-mode}.) See the
|
|
|
4999 file @file{etc/sample.init.el} (@file{etc/sample.emacs} in XEmacs
|
|
|
5000 versions prior to 21.4) for more information.
|

|
|
|
5011
|
|
|
5012 Well, first off, consider if you really want to do this. cc-mode is
|
|
|
5013 much more powerful than the old c-mode. If you're having trouble
|
|
|
5014 getting your old offsets to work, try using @code{c-set-offset} instead.
|
|
|
5015 You might also consider using the package @code{cc-compat}.
|
|
|
5016
|
|
462

5017 But, if you still insist, add the following lines to your @file{init.el}/@file{.emacs}:

|

|

|
|
|
5062 @end lisp
|
|
|
5063
|
|
|
5064 If you want to get fancy, try the @code{filladapt} package available
|
|
462
|
5065 standard with XEmacs. Put this into your @file{init.el}/@file{.emacs}:
|
|
428
|
5066
|
|
|
5067 @lisp
|
|

|

|
5072
|
|
|
5073 This will enable Filladapt for all modes except C mode, where it doesn't
|
|
|
5074 work well. To turn Filladapt on only in particular major modes, remove
|
|
|
5075 the @code{(setq-default ...)} line and use
|
|
|
5076 @code{turn-on-filladapt-mode}, like this:
|
|

5077
|
|
|
5078 @lisp
|

5079 (add-hook 'text-mode-hook 'turn-on-filladapt-mode)
|
|
428
|
5080 @end lisp
|
|
|
5081
|
|
|
5082 You can customize filling and adaptive filling with Customize.
|
|
|
5083 Select from the @code{Options} menu
|
|
462
|
5084 @code{Advanced (Customize)->Emacs->Editing->Fill->Fill...}

428

5085 or type @kbd{M-x customize @key{RET} fill @key{RET}}.
|
|
|
5086
|
|
|
5087 Note that well-behaving text-lookalike modes will run
|
|
|
5088 @code{text-mode-hook} by default (e.g. that's what Message does). For
|
|
|
5089 the nasty ones, you'll have to provide the @code{add-hook}s yourself.

|
|
|
5103 @strong{WARNING}: note that changing the value of
|
|
|
5104 @code{default-major-mode} from @code{fundamental-mode} can break a large
|
|
|
5105 amount of built-in code that expects newly created buffers to be in
|
|
|
5106 @code{fundamental-mode}. (Changing from @code{fundamental-mode} to
|
|
|
5107 @code{text-mode} might not wreak too much havoc, but changing to
|
|
|
5108 something more exotic like a lisp-mode would break many Emacs packages).
|
|
|
5109
|
|
|
5110 Note that Emacs by default starts up in buffer @code{*scratch*} in
|
|
|
5111 @code{initial-major-mode}, which defaults to
|
|
|
5112 @code{lisp-interaction-mode}. Thus adding the following form to your
|
|
|
5113 Emacs init file will cause the initial @code{*scratch*} buffer to be put
|
|
|
5114 into auto-fill'ed @code{text-mode}:
|
|
|
5115
|
|
|
5116 @lisp
|
|
|
5117 (setq initial-major-mode
|
|
|
5118 (lambda ()
|
|
|
5119 (text-mode)
|

|
5120 (turn-on-auto-fill)))
|
|
|
5121 @end lisp
|
|
|
5122
|
|
|
5123 Note that after your init file is loaded, if
|
|
|
5124 @code{inhibit-startup-message} is @code{nil} (the default) and the
|
|
|
5125 startup buffer is @code{*scratch*} then the startup message will be
|
|
|
5126 inserted into @code{*scratch*}; it will be removed after a timeout by
|
|
|
5127 erasing the entire @code{*scratch*} buffer. Keep in mind this default
|
|
|
5128 usage of @code{*scratch*} if you desire any prior manipulation of
|
|
|
5129 @code{*scratch*} from within your Emacs init file. In particular,
|
|
|
5130 anything you insert into @code{*scratch*} from your init file will be
|
|
|
5131 later erased. Also, if you change the mode of the @code{*scratch*}
|
|
|
5132 buffer, be sure that this will not interfere with possible later
|
|
|
5133 insertion of the startup message (e.g. if you put @code{*scratch*} into
|
|
|
5134 a nonstandard mode that has automatic font lock rules, then the startup
|
|
|
5135 message might get fontified in a strange foreign manner, e.g. as code in
|
|
|
5136 some programming language).

5158 @unnumberedsubsec Q5.0.7: Telnet from shell filters too much
|
|
|
5159
|
|
|
5160 I'm using the Emacs @kbd{M-x shell} function, and I would like to invoke
|
|
|
5161 and use a telnet session within it. Everything works fine except that
|
|
|
5162 now all @samp{^M}'s are filtered out by Emacs. Fixes?
|
|
|
5163
|
|
|
5164 Use @kbd{M-x rsh} or @kbd{M-x telnet} to open remote sessions rather
|
|
|
5165 than doing rsh or telnet within the local shell buffer. Starting with
|
|
|
5166 XEmacs-20.3 you can also use @kbd{M-x ssh} to open secure remote session
|
|
|
5167 if you have @code{ssh} installed.

5354 Emacs has a legacy of keyboards that produced characters with modifier
|
|
|
5355 bits, and therefore map a variety of input systems into this scheme even
|
|
|
5356 today. XEmacs is instead optimized for X events. This causes an
|
|
|
5357 incompatibility in the way key sequences are specified, but both Emacs
|
|
|
5358 and XEmacs will accept a key sequence as a vector of lists of modifiers
|
|
|
5359 that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
|
|
|
5360 @code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
|
|
|
5361 form for a single key, just (meta control a). Emacs has an abbreviated
|
|
|
5362 form for the Control and the Meta modifiers to string-characters (the
|
|
|
5363 ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
|
|
|
5364 that the abbreviated form works only for one-character key sequences,
|
|
|
5365 while Emacs users need to be aware that the string-character is rather
|
|
|
5366 limited. Specifically, the string-character can accommodate only 256
|
|
|
5367 different values, 128 of which have the Meta modifier and 128 of which
|
|
|
5368 have not. In each of these blocks, only 32 characters have the Control
|
|
|
5369 modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
|
|
|
5370 control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
|
|
|
5371 do not. Programmers are advised to use the full common form, both
|
|
|
5372 because it is more readable and less error-prone, and because it is
|
|
|
5373 supported by both Emacsen.

|
|
5374 @end quotation
|
|

5375

5376 Another (even safer) way to be sure of the key-sequences is to use the

|
|
5377 @code{read-kbd-macro} function, which takes a string like @samp{C-c
|
|
|
5378 <up>}, and converts it to the internal key representation of the Emacs
|
|
|
5379 you use. The function is available both on XEmacs and GNU Emacs.

5488 @code{\123} is a single key written in octal, and @code{< right >} is

5489 seven keys but @code{<right>} is a single function key. When in doubt,

5496 In most cases, not noticeable. Besides, there's no avoiding

5497 @code{let}---you have to bind your local variables, after all. Some
|
|
|

|
|
|
5499 function. I think because of clarity and maintenance (and possible
|
|
|
5500 future implementation), @code{let}-s should be used (nested) in a way to
|
|

5501 provide the clearest code.

|

5506 @itemize @bullet
|
|
|
5507 @item Global variables
|
|
|
5508
|
|
|
5509 You will typically @code{defvar} your global variable to a default
|
|
|
5510 value, and use @code{setq} to set it later.
|
|
|
5511
|
|
|
5512 It is never a good practice to @code{setq} user variables (like
|
|
|
5513 @code{case-fold-search}, etc.), as it ignores the user's choice
|
|
|
5514 unconditionally. Note that @code{defvar} doesn't change the value of a
|
|
|
5515 variable if it was bound previously. If you wish to change a
|
|
|
5516 user-variable temporarily, use @code{let}:
|
|
|
5517
|
|
|
5518 @lisp
|
|
|
5519 (let ((case-fold-search nil))
|
|
440
|
5520 ... ; code with searches that must be case-sensitive
|
|
428
|
5521 ...)
|
|
|
5522 @end lisp
|
|
|
5523
|
|
|
5524 You will notice the user-variables by their docstrings beginning with an
|
|
|
5525 asterisk (a convention).
|
|
|
5526
|
|
|
5527 @item Local variables
|
|
|
5528
|
|
|
5529 Bind them with @code{let}, which will unbind them (or restore their
|
|
|
5530 previous value, if they were bound) after exiting from the @code{let}
|
|
|
5531 form. Change the value of local variables with @code{setq} or whatever
|
|
|
5532 you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
|
|
|
5533 can even return one of its local variables.
|
|
|
5534
|
|
|
5535 Typical usage:
|
|
|
5536
|
|
|
5537 @lisp
|
|
|
5538 ;; iterate through the elements of the list returned by
|

5540 (let ((l (hairy-function-that-returns-list)))
|
|
|
5541 (while l
|
|
|
5542 ... do something with (car l) ...
|
|
|
5543 (setq l (cdr l))))
|
|
|
5544 @end lisp
|
|
|
5545
|
|
|
5546 Another typical usage includes building a value simply to work with it.
|
|
|
5547
|
|
|
5548 @lisp
|
|
|
5549 ;; Build the mode keymap out of the key-translation-alist

|

|
|
|
5553 inbox)
|
|
|
5554 @end lisp
|
|
|
5555
|
|
|
5556 This piece of code uses the local variable @code{inbox}, which becomes
|
|
|
5557 unbound (or regains old value) after exiting the form. The form also
|
|
|
5558 returns the value of @code{inbox}, which can be reused, for instance:
|
|
|
5559
|
|
|
5560 @lisp
|
|
|
5561 (setq foo-processed-inbox

5567 @unnumberedsubsec Q5.1.6: What is the typical misuse of @code{setq} ?
|
|
|
5568
|
|
|
5569 A typical misuse is probably @code{setq}ing a variable that was meant to
|
|
|
5570 be local. Such a variable will remain bound forever, never to be
|
|
|
5571 garbage-collected. For example, the code doing:
|
|
|
5572
|
|
|
5573 @lisp
|
|
|
5574 (defun my-function (whatever)
|
|
|
5575 (setq a nil)
|
|
|
5576 ... build a large list ...
|
|
|
5577 ... and exit ...)
|
|
|
5578 @end lisp
|
|
|
5579
|
|
|
5580 does a bad thing, as @code{a} will keep consuming memory, never to be
|
|
|
5581 unbound. The correct thing is to do it like this:
|
|
|
5582
|
|
|
5583 @lisp
|
|
|
5584 (defun my-function (whatever)
|
|
440
|
5585 (let (a) ; default initialization is to nil
|
|
428
|
5586 ... build a large list ...
|
|
|
5587 ... and exit, unbinding `a' in the process ...)
|
|
|
5588 @end lisp
|
|
|
5589
|
|
|
5590 Not only is this prettier syntactically, but it makes it possible for
|
|
|
5591 Emacs to garbage-collect the objects which @code{a} used to reference.
|
|
|
5592
|
|
|
5593 Note that even global variables should not be @code{setq}ed without
|
|
|
5594 @code{defvar}ing them first, because the byte-compiler issues warnings.
|
|
|
5595 The reason for the warning is the following:
|
|
|
5596
|
|
|
5597 @lisp
|
|
440
|
5598 (defun flurgoze nil) ; ok, global internal variable
|
|
428
|
5599 ...
|
|
|
5600
|
|
440
|
5601 (setq flurghoze t) ; ops! a typo, but semantically correct.
|
|
|
5602 ; however, the byte-compiler warns.
|
|

|
5615 Many of the advanced features of this package, such as @code{defun*},
|
|
|
5616 @code{loop}, and @code{setf}, are implemented as Lisp macros. In
|
|
|
5617 byte-compiled code, these complex notations will be expanded into
|
|
|
5618 equivalent Lisp code which is simple and efficient. For example, the
|
|
|
5619 forms
|
|
|
5620
|
|
|
5621 @lisp
|
|
|
5622 (incf i n)
|
|
|
5623 (push x (car p))
|
|
|
5624 @end lisp
|
|
|
5625
|
|
|
5626 are expanded at compile-time to the Lisp forms
|
|
|
5627
|
|
|
5628 @lisp
|
|
|
5629 (setq i (+ i n))
|
|
|
5630 (setcar p (cons x (car p)))
|
|
|
5631 @end lisp
|
|
|
5632
|
|
|
5633 which are the most efficient ways of doing these respective operations
|
|
|
5634 in Lisp. Thus, there is no performance penalty for using the more
|
|
|
5635 readable @code{incf} and @code{push} forms in your compiled code.
|
|
|
5636
|
|
|
5637 @emph{Interpreted} code, on the other hand, must expand these macros
|
|
|
5638 every time they are executed. For this reason it is strongly
|
|
|
5639 recommended that code making heavy use of macros be compiled. (The
|
|
|
5640 features labelled @dfn{Special Form} instead of @dfn{Function} in this
|
|
|
5641 manual are macros.) A loop using @code{incf} a hundred times will
|
|
|
5642 execute considerably faster if compiled, and will also garbage-collect
|
|
|
5643 less because the macro expansion will not have to be generated, used,
|
|
|
5644 and thrown away a hundred times.
|
|
|
5645
|
|
|
5646 You can find out how a macro expands by using the @code{cl-prettyexpand}
|
|
|
5647 function.

5653 Yes. Emacs byte-compiler cannot do much to optimize recursion. But

5654 think well whether this is a real concern in Emacs. Much of the Emacs

|

5674
|

5675 Replace @samp{FORMAT} with an unquoted symbol representing the format of
|
|
|
5676 the image (e.g. @code{xpm}, @code{xbm}, @code{gif}, @code{jpeg}, etc.)
|
|
|
5677 Instead of @samp{FILE}, use the image file name
|
|
|
5678 (e.g.
|
|

5679 @iftex

5772 I'm having some trouble with sounds I've downloaded from sunsite. They
|
|
|
5773 play when I run them through @code{showaudio} or cat them directly to
|
|
|
5774 @file{/dev/audio}, but XEmacs refuses to play them.

5779 [Many of] These files have an (erroneous) 24byte header that tells about
|
|
|
5780 the format that they have been recorded in. If you cat them to
|
|
|
5781 @file{/dev/audio}, the header will be ignored and the default behavior
|
|
|
5782 for /dev/audio will be used. This happens to be 8kHz uLaw. It is
|
|
|
5783 probably possible to fix the header by piping through @code{sox} and
|
|
|
5784 passing explicit parameters for specifying the sampling format; you then
|
|
|
5785 need to perform a 'null' conversion from SunAudio to SunAudio.

5790 @unnumberedsubsec Q5.3.1: How do you make XEmacs indent CL if-clauses correctly?
|
|
|
5791
|
|
|
5792 I'd like XEmacs to indent all the clauses of a Common Lisp @code{if} the
|
|
|
5793 same amount instead of indenting the 3rd clause differently from the
|
|
|
5794 first two.
|
|
|
5795
|
|
462
|
5796 One way is to add, to @file{init.el}/@file{.emacs}:
|
|
428
|
5797
|
|
|
5798 @lisp
|
|
|
5799 (put 'if 'lisp-indent-function nil)
|
|
|
5800 @end lisp
|
|
|
5801
|
|
|
5802 However, note that the package @code{cl-indent} that comes with
|
|
|
5803 XEmacs sets up this kind of indentation by default. @code{cl-indent}
|
|
|
5804 also knows about many other CL-specific forms. To use @code{cl-indent},
|
|
|
5805 one can do this:
|
|
|
5806
|
|
|
5807 @lisp
|
|
|
5808 (load "cl-indent")
|
|
|
5809 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
|
5810 @end lisp
|
|
|
5811
|
|
|
5812 One can also customize @file{cl-indent.el} so it mimics the default
|
|
|
5813 @code{if} indentation @code{then} indented more than the @code{else}.
|
|
|
5814 Here's how:
|
|
|
5815
|
|
|
5816 @lisp
|
|
|
5817 (put 'if 'common-lisp-indent-function '(nil nil &body))
|
|
|
5818 @end lisp
|
|
|
5819
|
|
|
5820 Also, a new version (1.2) of @file{cl-indent.el} was posted to
|
|
|
5821 comp.emacs.xemacs on 12/9/94. This version includes more documentation
|
|
|
5822 than previous versions. This may prove useful if you need to customize
|
|
|
5823 any indent-functions.

5842

5843 My printer is a Postscript printer and @code{lpr} only works for

|
|
|
5846
|

5847 Put something like this in your @file{init.el}/@file{.emacs}:

5854 If you don't use a2ps to convert ASCII to postscript (why not, it's
|
|
|
5855 free?), replace with the command you do use. Note also that some
|
|

5856 versions of a2ps require a @samp{-Pprinter} to ensure spooling.

5859 @unnumberedsubsec Q5.3.5: How do I specify the paths that XEmacs uses for finding files?
|
|
|
5860
|
|
|
5861 You can specify what paths to use by using a number of different flags
|
|
|
5862 when running configure. See the section MAKE VARIABLES in the top-level
|
|
|
5863 file INSTALL in the XEmacs distribution for a listing of those flags.
|
|
|
5864
|
|
|
5865 Most of the time, however, the simplest fix is: @strong{do not} specify
|
|
|
5866 paths as you might for GNU Emacs. XEmacs can generally determine the
|
|
|
5867 necessary paths dynamically at run time. The only path that generally
|
|
|
5868 needs to be specified is the root directory to install into. That can
|
|
|
5869 be specified by passing the @code{--prefix} flag to configure. For a
|
|
|
5870 description of the XEmacs install tree, please consult the @file{NEWS}
|
|
|
5871 file.

|

5892
|
|
|
5893 Since this is XEmacs, you can specify an icon to be shown on
|

5894 window-system devices. To do so, change the @code{make-glyph} call to
|
|
|
5895 something like this:
|
|
|
5896
|
|
|
5897 @lisp
|
|

5898 (make-glyph '([xpm :file "~/something.xpm"]

5899 [string :data "[END]"]))
|
|
|
5900 @end lisp
|
|
|
5901
|
|
|
5902 You can inline the @sc{xpm} definition yourself by specifying
|
|
|
5903 @code{:data} instead of @code{:file}. Here is such a full-featured
|
|
|
5904 version that works on both X and TTY devices:

|
|
5955 Yes, abbrevs only expands word-syntax strings. While XEmacs does not
|
|
|
5956 prevent you from defining (e.g. with @kbd{C-x a g} or @kbd{C-x a l})
|
|
|
5957 abbrevs that contain special characters, it will refuse to expand
|
|
|
5958 them. So you need to ensure, that the abbreviation contains letters and
|
|
|
5959 digits only. This means that @samp{xd}, @samp{d5}, and @samp{5d} are
|
|
|
5960 valid abbrevs, but @samp{&d}, and @samp{x d} are not.
|
|
|
5961
|
|
|
5962 If this sounds confusing to you, (re-)read the online documentation for
|
|
|
5963 abbrevs (@kbd{C-h i m XEmacs @key{RET} m Abbrevs @key{RET}}), and then come back and

5964 read this question/answer again.

5987 @example

5989 @end example
|
|
|
5990
|
|
|
5991 @item
|
|
|
5992 Then be sure to quote things that are necessary for emacs strings:
|
|
|
5993
|
|
|
5994 @example
|
|
|
5995 cat ./file.face | sed 's/\\/\\\\/g'
|
|

5996 @iftex
|
|
|
5997 \ @*
|

|
|
|
6000 @end example
|
|
|
6001
|
|
|
6002 @item
|
|
|
6003 Then set up emacs to include the file as a mail header - there were a
|
|
|
6004 couple of suggestions here---either something like:
|
|
|
6005
|
|
|
6006 @lisp
|
|
|
6007 (setq mail-default-headers
|
|
|
6008 "X-Face: @email{Ugly looking text string here}")
|
|
|
6009 @end lisp
|
|
|
6010
|
|
|
6011 Or, alternatively, as:
|
|
|
6012
|
|
|
6013 @lisp
|
|
|
6014 (defun mail-insert-x-face ()
|
|
|
6015 (save-excursion
|
|
|
6016 (goto-char (point-min))
|
|
|
6017 (search-forward mail-header-separator)
|
|
|
6018 (beginning-of-line)
|
|
|
6019 (insert "X-Face:")
|
|
|
6020 (insert-file-contents "~/.face")))
|
|
|
6021
|
|
|
6022 (add-hook 'mail-setup-hook 'mail-insert-x-face)
|
|
|
6023 @end lisp
|
|
|
6024 @end enumerate
|
|
|
6025
|
|
|
6026 However, 2 things might be wrong:
|
|
|
6027
|
|
|
6028 Some versions of pbmtoicon produces some header lines that is not
|
|
|
6029 expected by the version of compface that I grabbed. So I found I had to
|
|
|
6030 include a @code{tail +3} in the pipeline like this:
|
|
|
6031
|
|
|
6032 @example
|
|
|
6033 cat file.xbm | xbm2ikon | tail +3 |compface > file.face
|
|
|
6034 @end example
|
|
|
6035
|
|
|
6036 Some people have also found that if one uses the @code{(insert-file)}
|
|
|
6037 method, one should NOT quote the face string using the sed script .
|
|
|
6038
|
|
|
6039 It might also be helpful to use @email{stig@@hackvan.com, Stig's} script
|
|
|
6040 (included in the compface distribution at XEmacs.org) to do the
|
|
430
|
6041 conversion.

6101 @unnumberedsubsec Q5.3.12: What do I need to change to make printing work?
|
|
|
6102
|
|
|
6103 For regular printing there are two variables that can be customized.
|
|
|
6104
|
|
|
6105 @table @code
|
|
|
6106 @item lpr-command
|
|
|
6107 This should be set to a command that takes standard input and sends
|
|
|
6108 it to a printer. Something like:
|
|
|
6109
|
|
|
6110 @lisp
|
|
|
6111 (setq lpr-command "lp")
|
|
|
6112 @end lisp
|
|
|
6113
|
|
|
6114 @item lpr-switches
|
|
|
6115 This should be set to a list that contains whatever the print command
|
|
|
6116 requires to do its job. Something like:
|
|
|
6117
|
|
|
6118 @lisp
|
|
|
6119 (setq lpr-switches '("-depson"))
|
|
|
6120 @end lisp
|
|
|
6121 @end table
|
|
|
6122
|
|
|
6123 For postscript printing there are three analogous variables to
|
|
|
6124 customize.
|
|
|
6125
|
|
|
6126 @table @code
|
|
|
6127 @item ps-lpr-command
|
|
|
6128 This should be set to a command that takes postscript on standard input
|
|
|
6129 and directs it to a postscript printer.
|
|
|
6130
|
|
|
6131 @item ps-lpr-switches
|
|
|
6132 This should be set to a list of switches required for
|
|
|
6133 @code{ps-lpr-command} to do its job.
|
|
|
6134
|
|
|
6135 @item ps-print-color-p
|
|
|
6136 This boolean variable should be set @code{t} if printing will be done in
|
|
|
6137 color, otherwise it should be set to @code{nil}.
|
|
|
6138 @end table
|
|
|
6139
|
|
|
6140 NOTE: It is an undocumented limitation in XEmacs that postscript
|
|
|
6141 printing (the @code{Pretty Print Buffer} menu item) @strong{requires} a
|
|
|
6142 window system environment. It cannot be used outside of X11.

6193
|
|

6194 Beginning with release 21.0, XEmacs has worked under MS Windows. A
|
|
|
6195 group of dedicated developers actively maintains and improves the
|
|
|
6196 Windows-specific portions of the code. The mailing list at
|
|
|
6197 @email{xemacs-nt@@xemacs.org} is dedicated to that effort (please use
|
|
|
6198 the -request address to subscribe). (Despite its name, XEmacs actually
|
|
|
6199 works on all versions of Windows.)
|
|
|
6200
|
|
|
6201 As of May 2001, XEmacs on MS Windows is stable and full-featured, and
|
|
|
6202 has been so for a year or more -- in fact, some features, such as
|
|
|
6203 printing, actually work better on Windows than native Unix. However,
|
|
|
6204 the internationalization (Mule) support does not work -- although this
|
|
|
6205 is being actively worked on.

|
|
|
6242
|
|
|
6243 It depends on the knowledge and time you possess. If you are a
|
|
|
6244 programmer, try to build XEmacs and see if you can improve it.
|
|
|
6245 Windows-specific improvements like integration with established
|
|
|
6246 Windows environments are especially sought after.
|
|
|
6247
|
|
|
6248 Otherwise, you can still help by downloading the binaries, using
|
|
|
6249 XEmacs as your everyday editor and reporting bugs you find to the
|
|
|
6250 mailing list.
|
|
|
6251
|

|
|
|

6254 small step in that direction.

|
|
|
6258
|
|
|
6259 To answer the second part of the question: No, you, you don't need
|
|
|
6260 Cygwin or MinGW to build or to run XEmacs. But if you have them and
|
|
|
6261 want to use them, XEmacs supports these environments.
|
|
|
6262
|
|
|
6263 (One important reason to support Cygwin is that it lets the MS Windows
|
|
|
6264 developers test out their code in a Unix environment without actually
|
|
|
6265 having to have a Unix machine around. For this reason alone, Cygwin
|
|
|
6266 support is likely to remain supported for a long time in XEmacs. Same
|
|
|
6267 goes for the X support under Cygwin, for the same reasons. MinGW
|
|
|
6268 support, on the other hand, depends on volunteers to keep it up to date;
|
|
|
6269 but this is generally not hard.)
|
|
|
6270
|
|
|
6271 Cygwin is a set of tools providing Unix-like API on top of Win32.
|
|
|
6272 It makes it easy to port large Unix programs without significant
|
|
|
6273 changes to their source code. It is a development environment as well
|
|
|
6274 as a runtime environment.
|
|
|
6275
|
|
|
6276 When built with Cygwin, XEmacs supports all display types -- TTY, X &
|
|
|
6277 Win32 GUI, and can be built with support for all three simultaneously.
|
|
|
6278 If you build with Win32 GUI support then the Cygwin version uses the
|
|
|
6279 majority of the Windows-specific code, which is mostly related to
|
|
|
6280 display. If you want to build with X support you need X libraries (and
|
|
|
6281 an X server to display XEmacs on); see @ref{Q6.1.4}. TTY and Win32 GUI
|
|
|
6282 require no additional libraries beyond what comes standard with Cygwin.
|
|
|
6283
|
|
|
6284 The advantages of the Cygwin version are that it integrates well with
|
|
|
6285 the Cygwin environment for existing Cygwin users; uses configure so
|
|
|
6286 building with different features is very easy; and actively supports X &
|
|
|
6287 TTY. Furthermore, the entire Cygwin environment and compiler are free,
|
|
|
6288 whereas Visual C++ costs money.
|
|
|
6289
|
|
|
6290 The disadvantage is that it requires the whole Cygwin environment,
|
|
|
6291 whereas the native port requires only a suitable MS Windows compiler.
|
|
|
6292 Also, it follows the Unix filesystem and process model very closely
|
|
|
6293 (some will undoubtedly view this as an advantage).
|
|
|
6294
|
|
|
6295 See @uref{http://sources.redhat.com/cygwin/} for more information on
|
|
|
6296 Cygwin.
|
|
|
6297
|
|
|
6298 MinGW is a collection of header files and import libraries that allow
|
|
|
6299 one to use GCC under the Cygwin environment to compile and produce
|
|
|
6300 exactly the same native Win32 programs that you can using Visual C++.
|
|
|
6301 Programs compiled with MinGW make use of the standard Microsoft runtime
|
|
|
6302 library @file{MSVCRT.DLL}, present on all Windows systems, and look,
|
|
|
6303 feel, and act like a standard Visual-C-produced application. (The only
|
|
|
6304 difference is the compiler.) This means that, unlike a
|
|
|
6305 standardly-compiled Cygwin application, no extra runtime support
|
|
|
6306 (e.g. Cygwin's @file{cygwin1.dll}) is required. This, along with the
|
|
|
6307 fact that GCC is free (and works in a nice Unix-y way in a nice Unix-y
|
|
|
6308 environment, for those die-hard Unix hackers out there), is the main
|
|
|
6309 advantage of MinGW. It is also potentially faster than Cygwin because
|
|
|
6310 it has less overhead when calling Windows, but you lose the POSIX
|
|
|
6311 emulation layer, which makes Unix programs harder to port. (But this is
|
|
|
6312 irrelevant for XEmacs since it's already ported to Win32.)
|
|
|
6313
|
|
|
6314 See @uref{http://www.mingw.org/} for more information on MinGW.

6317 @unnumberedsubsec Q6.0.7: What exactly are all the different ways to build XEmacs under Windows?
|
|
|
6318
|
|
|
6319 XEmacs can be built in several ways in the MS Windows environment.
|
|
462
|
6320
|
|
|
6321 The standard way is what we call the "native" port. It uses the Win32
|
|
|
6322 API and has no connection with X whatsoever -- it does not require X
|
|
|
6323 libraries to build, nor does it require an X server to run. The native
|
|
|
6324 port is the most reliable version and provides the best graphical
|
|
|
6325 support. Almost all development is geared towards this version, and
|
|
|
6326 there is little reason not to use it.
|
|
|
6327
|
|
593
|
6328 The second way to build is the Cygwin port. It takes advantage of
|
|
|
6329 Cygnus emulation library under Win32. @xref{Q6.0.6}, for more
|
|
|
6330 information.
|
|
|
6331
|
|
|
6332 A third way is the MinGW port. It uses the Cygwin environment to build
|
|
|
6333 but does not require it at runtime. @xref{Q6.0.6}, for more
|
|
|
6334 information.
|
|
|
6335
|
|
|
6336 Finally, you might also be able to build the non-Cygwin, non-MinGW "X"
|
|
|
6337 port. This was actually the first version of XEmacs that ran under MS
|
|
|
6338 Windows, and although the code is still in XEmacs, it's essentially
|
|
|
6339 orphaned and it's unlikely it will compile without a lot of work. If
|
|
|
6340 you want an MS Windows versin of XEmacs that supports X, use the Cygwin
|
|
|
6341 version. (The X support there is actively maintained, so that Windows
|
|
|
6342 developers can test the X support in XEmacs.)

6462

6463 As of May 2001, we are recommending that you use the port of XFree86 to

6464 Cygwin. This has recently stabilized, and will undoubtedly soon make
|
|
|
6465 most other MS Windows X servers obsolete. It is what the Windows
|
|
|
6466 developers use to test the MS Windows X support.
|
|
|
6467
|
|
|
6468 To install, go to @uref{http://xfree86.cygwin.com/}. There is a
|
|
|
6469 detailed description on that site of exactly how to install it. This
|
|
|
6470 installation also provides the libraries, include files, and other stuff
|

6471 needed for development; a large collection of internationalized fonts;
|
|

6472 the standard X utilities (xterm, twm, etc.) -- in a word, the works.

6474 NOTE: As of late May 2001, there is a bug in the file

6475 @file{startxwin.bat}, used to start X Windows. It passes the option

6485 find the X libraries and compile with X support.

6486
|
|

6487 As noted above, the non-Cygwin X support is basically orphaned, and
|
|
|
6488 probably won't work. But if it want to try, it's described in
|
|
|
6489 @file{nt/README} in some detail. Basically, you need to get X11
|
|

6490 libraries from ftp.x.org, and compile them. If the precompiled versions

|
|
|
6497
|
|
611
|
6498 The XEmacs (and Emacs in general) user interface is pretty different
|
|
|
6499 from what is expected of a typical MS Windows program. How does the MS
|
|
|
6500 Windows port cope with it?
|
|
593
|
6501
|
|
|
6502 As a general rule, we follow native MS Windows conventions as much as
|
|
611
|
6503 possible. 21.4 is a fairly complete Windows application, supporting
|
|
|
6504 native printing, system file dialog boxes, tool tips, etc. In cases
|
|
|
6505 where there's a clear UI conflict, we currently use normal Unix XEmacs
|
|
|
6506 behavior by default, but make sure the MS Windows "look and feel" (mark
|
|
|
6507 via shift-arrow, self-inserting deletes region, Alt selects menu items,
|
|
|
6508 etc.) is easily configurable (respectively: using the variable
|
|
|
6509 @code{shifted-motion-keys-select-region} in 21.4 and above [it's in fact
|
|
|
6510 the default in these versions], or the @file{pc-select} package; using
|
|
|
6511 the @file{pending-del} package; and setting the variable
|
|
|
6512 @code{menu-accelerator-enabled} to @code{menu-force} in 21.4 and above).
|
|
|
6513 In fact, if you use the sample @file{init.el} file as your init file,
|
|
|
6514 you will get all these behaviors automatically turned on.
|
|
593
|
6515
|
|
|
6516 In future versions, some of these features might be turned on by

|
|
|
6616
|
|
|
6617 In his flavor of Emacs 20, Richard Stallman has renamed all the @samp{win32-*}
|
|
|
6618 symbols to @samp{w32-*}. Does XEmacs do the same?
|
|
|
6619
|
|
|
6620 We consider such a move counter-productive, thus we do not use the
|
|
|
6621 @samp{w32} prefix. (His rather questionable justification was that he
|
|
|
6622 did not consider Windows to be a "winning" platform.) However, the name
|
|
|
6623 @samp{Win32} is not particularly descriptive outside the Windows world,
|
|
|
6624 and using just @samp{windows-} would be too generic. So we chose a
|
|
|
6625 compromise, the prefix @samp{mswindows-} for Windows-related variables
|
|
|
6626 and functions.
|
|
|
6627
|
|
|
6628 Thus all the XEmacs variables and functions directly related to either
|
|
|
6629 the Windows GUI or OS are prefixed @samp{mswindows-} (except for a
|
|
|
6630 couple of debugging variables, prefixed @samp{debug-mswindows-}). From
|
|
|
6631 an architectural perspective, however, we believe that this is mostly a
|
|
|
6632 non-issue because there should be a very small number of
|
|
|
6633 window-systems-specific variables anyway. Whenever possible, we try to

6634 provide generic interfaces that apply to all window systems.

6660 in such a way to allow clean support of multiple window systems. At

6661 this time the TTY support was added, making X and TTY the first two

6662 "window systems" supported by XEmacs. The 19.12 design is the basis for

6707 Win-Emacs was a port of Lucid Emacs 19.6 to MS Windows using X
|
|
|
6708 compatibility libraries. Win-Emacs was written by Ben Wing. The MS
|
|
|
6709 Windows code never made it back to Lucid Emacs, and its creator (Pearl
|
|
|
6710 Software) has long since gone out of business.

6731 Starting with version 19.30, it has been possible to compile GNU Emacs
|
|
|
6732 under MS Windows using the DJGPP compiler and X libraries. The result
|
|
611
|
6733 is very similar to GNU Emacs compiled under MS DOS, only it works
|
|
|
6734 somewhat better because it runs in 32-bit mode, makes use of all the

6742 @unnumberedsubsec Q6.3.3: XEmacs 21.1 on Windows used to spawn an ugly console window on every startup. Has that been fixed?
|
|
|
6743
|
|
|
6744 Yes.
|
|
|
6745
|
|
|
6746 The console was there because @file{temacs} (and in turn, @file{xemacs})
|
|
|
6747 was a console application, and Windows typically creates a new
|
|
|
6748 console for a console process unless the creating process requests that
|
|
|
6749 one isn't created. This used to be fixed with @file{runemacs}, a small
|
|
|
6750 Windows application that existed merely to start @file{xemacs}, stating
|
|
|
6751 that it didn't want a console.
|
|
|
6752
|
|
|
6753 XEmacs 21.4 fixes this cleanly by the virtue of being a true "GUI"
|
|
|
6754 application. The explanation of what that means is included for
|
|
|
6755 educational value.
|
|
|
6756
|
|
|
6757 When building an application to be run in a Win32 environment, you must
|
|
|
6758 state which sub-system it is to run in. Valid subsystems include
|
|
|
6759 "console" and "gui". The subsystem you use affects the run time
|
|
|
6760 libraries linked into your application, the start up function that is
|
|
|
6761 run before control is handed over to your application, the entry point
|
|
|
6762 to your program, and how Windows normally invokes your program. (Console
|
|
|
6763 programs automatically get a console created for them at startup if
|
|
|
6764 their stdin/stdout don't point anywhere useful, which is the case when
|
|
|
6765 run from the GUI. This is a stupid design, of course -- instead, the
|
|
|
6766 console should get created only when the first I/O actually occurs!
|
|
|
6767 GUI programs have an equally stupid design: When called from
|
|
|
6768 @file{CMD.EXE}/@file{COMMAND.COM}, their stdin/stdout will be set to
|
|
|
6769 point nowhere useful, even though the command shell has its own
|
|
|
6770 stdin/stdout. It's as if someone who had learned a bit about stdio but
|
|
|
6771 had no actual knowledge of interprocess communication designed the
|
|
|
6772 scheme; unfortunately, the whole process-communication aspect of the
|
|
|
6773 Win32 API is equally badly designed.) For example, the entry point for a
|
|
|
6774 console app is "main" (which is what you'd expect for a C/C++ program),
|
|
|
6775 but the entry point for a "gui" app is "WinMain". This confuses and
|
|
|
6776 annoys a lot of programmers who've grown up on Unix systems, where the
|
|
|
6777 kernel doesn't really care whether your application is a gui program or
|
|
|
6778 not.
|
|
|
6779
|
|
|
6780 For reasons not altogether clear, and are lost in the mists of time and
|
|
|
6781 tradition, XEmacs on Win32 started out as a console application, and
|
|
|
6782 therefore a console was automatically created for it. (It may have been
|
|
|
6783 made a console application partly because a console is needed in some
|
|
|
6784 circumstances, especially under Win95, to interrupt, terminate, or send
|
|
|
6785 signals to a child process, and because of the bogosity mentioned above
|
|
|
6786 with GUI programs and the standard command shell. Currently, XEmacs
|
|
|
6787 just creates and immediately hides a console when necessary, and
|
|
|
6788 works around the "no useful stdio" problem by creating its own console
|
|
|
6789 window as necessary to display messages in.)

|
|
442
|
6808
|
|
|
6809 XEmacs relies on a process called "dumping" to generate a working
|
|
|
6810 executable. Under MS-Windows this process effectively fixes the memory
|
|
|
6811 addresses of information in the executable. When XEmacs starts up it tries
|
|
|
6812 to reserve these memory addresses so that the dumping process can be
|
|
593
|
6813 reversed -- putting the information back at the correct addresses.
|
|
|
6814 Unfortunately some .DLLs (for instance the soundblaster driver) occupy
|
|
442
|
6815 memory addresses that can conflict with those needed by the dumped XEmacs
|
|
|
6816 executable. In this instance XEmacs will fail to start without any
|
|
|
6817 explanation. Note that this is extremely machine specific.
|
|
|
6818
|
|
|
6819 21.1.10 includes a fix for this that makes more intelligent guesses
|
|
|
6820 about which memory addresses will be free, and this should cure the
|
|
593
|
6821 problem for most people. 21.4 implements "portable dumping", which
|
|
|
6822 eliminates the problem altogether. We recommend you use the 21.4
|
|
|
6823 binaries, but you can use the 21.1 binaries if you are very paranoid
|

6873
|
|
|
6874 21.4 was the "stable" version of the 21.2 series, which was considered
|
|
|
6875 "experimental" throughout its life; thus there were no "official"
|
|
|
6876 releases at all. In essence, XEmacs is now following the "alternating"
|
|
|
6877 scheme of Linux, where at any point there are at least two different
|
|
|
6878 development branches, one "stable" and one "experimental". Periodic
|
|
|
6879 releases happen in both branches, but those in the experimental branch
|
|
|
6880 are not tested as well, and there's no guarantee they will work at all.
|
|
|
6881 The experiemental branch is open to any and all code that's acceptable
|
|
|
6882 to the developers; the stable branch, however, is in general limited
|
|
|
6883 only to bug fixes, and all contributions are carefully reviewed to make
|
|
|
6884 sure they will increase and not decrease stability.
|
|
|
6885
|
|
|
6886 21.3 never existed at all; it was decided to follow the Linux scheme
|
|
|
6887 exactly, where odd-numbered series are experimental and even-numbered
|
|
|
6888 ones stable.
|
|
|

|

7129
|
|
|
7130 XEmacs 20.4 is a bugfix release with no user-visible changes.

7135
|
|
|
7136 XEmacs 20.3 was released in November 1997. It contains many bugfixes,
|
|
|
7137 and a number of new features, including Autoconf 2 based configuration,
|
|
|
7138 additional support for Mule (Multi-language extensions to Emacs), many
|
|
|
7139 more customizations, multiple frames on TTY-s, support for multiple info
|
|
|
7140 directories, an enhanced gnuclient, improvements to regexp matching,
|
|
|
7141 increased MIME support, and many, many synches with GNU Emacs 20.
|
|
|
7142
|
|
|
7143 The XEmacs/Mule support has been only seriously tested in a Japanese
|
|
|
7144 locale, and no doubt many problems still remain. The support for
|
|
|
7145 ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
|
|
440
|
7146 price---about a 30% slowdown from 19.16. We're making progress on
|
|
428
|
7147 improving performance and XEmacs 20.3 compiled without Mule (which is
|
|
|
7148 the default) is definitely faster than XEmacs 19.16.
|
|
|
7149
|
|
|
7150 XEmacs 20.3 is the first non-beta v20 release, and will be the
|
|
|
7151 basis for all further development.

7154 @unnumberedsubsec Q7.0.6: What's new in XEmacs 20.2?
|
|
|
7155
|
|
|
7156 The biggest changes in 20.2 include integration of EFS (the next
|
|
|
7157 generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
|
|
|
7158 major mode for editing Tex and LaTeX, and a lot of other stuff). Many
|
|
|
7159 bugs from 20.0 have been fixed for this release. 20.2 also contains a
|
|
|
7160 new system for customizing XEmacs options, invoked via @kbd{M-x
|
|
|
7161 customize}.
|
|
|
7162
|
|
|
7163 XEmacs 20.2 is the development release (20.0 was beta), and is no longer
|
|
|
7164 considered unstable.
