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

454 The previous maintainer of the FAQ was @email{rossini@@biostat.washington.edu,
|

428
|
455 Anthony Rossini}, who started it, after getting tired of hearing JWZ
|
|
|
456 complain about repeatedly having to answer questions.
|
|
|
457 @email{ben@@xemacs.org, Ben Wing} and @email{cthomp@@xemacs.org, Chuck
|
|
|
458 Thompson}, the principal authors of XEmacs, then took over and Ben did
|
|
|
459 a massive update reorganizing the whole thing. At which point Anthony
|
|
|
460 took back over, but then had to give it up again. Some of the other
|

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

525 XEmacs is a powerful, highly customizable open source text editor and
|
|
|
526 application development system, with full GUI support. It is protected
|
|
|
527 under the GNU Public License and related to other versions of Emacs, in
|
|
|
528 particular GNU Emacs. Its emphasis is on modern graphical user
|
|
|
529 interface support and an open software development model, similar to
|
|
|
530 Linux. XEmacs has an active development community numbering in the
|
|
|
531 hundreds (and thousands of active beta testers on top of this), and runs
|
|
|
532 on all versions of MS Windows, on Linux, and on nearly every other
|
|
|
533 version of Unix in existence. Support for XEmacs has been supplied by
|
|
|
534 Sun Microsystems, University of Illinois, Lucid, ETL/Electrotechnical
|
|
|
535 Laboratory, Amdahl Corporation, BeOpen, and others, as well as the
|
|
|
536 unpaid time of a great number of individual developers.

629 @unnumberedsubsec Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged?
|
|
|
630
|
|
|
631 There are currently irreconcilable differences in the views about
|
|
|
632 technical, programming, design and organizational matters between RMS
|
|
|
633 and the XEmacs development team which provide little hope for a merge to
|
|
|
634 take place in the short-term future.
|
|
|
635
|
|
|
636 If you have a comment to add regarding the merge, it is a good idea to
|
|
|
637 avoid posting to the newsgroups, because of the very heated flamewars
|
|
|
638 that often result. Mail your questions to @email{xemacs-beta@@xemacs.org} and

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

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

|
927
|
|
|
928 Both the stable and development versions of XEmacs include
|
|
1135
|
929 internationalization support (aka MULE). MULE currently (21.4) works on
|
|
|
930 UNIX and Linux systems. It is possible to build with MULE on Windows
|
|
|
931 systems, but if you really need MULE on Windows, it is recommended that
|
|
|
932 you build and use the development (21.5) version, and deal with the
|
|
|
933 instability of the development tree. Binaries compiled without MULE
|
|
|
934 support run faster than MULE capable XEmacsen.

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

963 The message-catalog support was written but is badly bit-rotted. XEmacs

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

980 @unnumberedsubsec Q1.3.5: Please explain the various input methods in MULE/XEmacs
|
|
428
|
981
|
|
1135
|
982 Mule supports a wide variety of input methods. There are three basic
|
|
|
983 classes: Lisp implementations, generic platform support, and library
|
|
|
984 interfaces.
|
|
|
985
|
|
|
986 @emph{Lisp implementations} include Quail, which provides table-driven input
|
|
|
987 methods for almost all the character sets that Mule supports (including
|
|
|
988 all of the ISO 8859 family, the Indic languages, Thai, and so on), and
|
|
|
989 SKK, for Japanese. (SKK also supports an interface to an external
|
|
|
990 "dictionary server" process.) Quail supports both typical "dead-key"
|
|
|
991 methods (eg, in the "latin-1-prefix" method, @kbd{" a} produces ä, LATIN
|
|
|
992 SMALL LETTER A WITH DIAERESIS), and the complex dictionary-based phonetic
|
|
|
993 methods used for Asian ideographic languages like Chinese.
|
|
|
994
|
|
|
995 Lisp implementations can be less powerful (but they are not perceptibly
|
|
|
996 inefficient), and of course are not portable to non-Emacs applications.
|
|
|
997 The incompatibility can be very annoying. On the other hand, they
|
|
|
998 require no special platform support or external libraries, so if you can
|
|
|
999 display the characters, Mule can input them for you and you can edit,
|
|
|
1000 anywhere.
|
|
|
1001
|
|
|
1002 @emph{Generic platform support} is currently limited to the X Input
|
|
|
1003 Method (XIM) framework, although support for MSIME (for MS Windows) is
|
|
|
1004 planned, and IIIMF (Sun's Internet-Intranet Input Method Framework)
|
|
|
1005 support is extremely desirable. XIM is enabled at build time by use of
|
|
|
1006 the @samp{--with-xim} flag to @code{configure}. For use of XIM, see
|
|
|
1007 your platform documentation. However, normally the input method you use
|
|
|
1008 is specified via the @samp{LANG} and @samp{XMODIFIERS} environment
|
|
|
1009 variables.
|
|
|
1010
|
|
|
1011 Of course, input skills are portable across most applications. However,
|
|
|
1012 especially in modern GUI systems the habit of using bucky bits has
|
|
|
1013 fallen into sad disuse, and many XIM systems are poorly configured for
|
|
|
1014 use with Emacs. For example, the kinput2 input manager (a separate
|
|
|
1015 process providing an interface between Japanese dictionary servers such
|
|
|
1016 as Canna and Wnn, and the application) tends to gobble up keystrokes
|
|
|
1017 generating Meta characters. This means that to edit while using an XIM
|
|
|
1018 input method, you must toggle the input method off every time you want
|
|
|
1019 to use @kbd{M-f}. Your mileage may vary.
|
|
|
1020
|
|
|
1021 @emph{Library interfaces} are most common for Japanese, although Wnn
|
|
|
1022 supports Chinese (traditional and simplified) and Korean. There are
|
|
|
1023 Chinese and Korean input servers available, but we do not know of any
|
|
|
1024 patches for XEmacs to use them directly. You can use them via
|
|
|
1025 IM-enabled terminals, by manipulating the terminal coding systems. We
|
|
|
1026 describe only the Japanese-oriented systems here. The advantage of
|
|
|
1027 these systems is that they are very powerful, and on platforms where
|
|
|
1028 they are available there is typically a wide range of applications that
|
|
|
1029 support them. Thus your input skills are portable across applications.
|
|
|
1030
|
|
|
1031 Mule provides built-in interfaces to the following input methods: Wnn4,
|
|
|
1032 Wnn6, Canna, and SJ3. These can be configured at build time. There are
|
|
|
1033 patches available (no URL, sorry) to support the SKK server, as well.
|
|
|
1034 Wnn and SJ3 use the @code{egg} user interface. The interface for Canna
|
|
|
1035 is specialized to Canna.
|
|
428
|
1036
|
|
|
1037 Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
|
|
1135
|
1038 University. It is a powerful and complex system. Wnn4 is free and Wnn6
|
|
|
1039 is not. Wnn uses grammatical hints and probability of word association,
|
|
|
1040 so in principle Wnn can be cleverer than other methods.
|
|
|
1041
|
|
|
1042 Canna, made by NEC, supports only Japanese. It is a simple and powerful
|
|
|
1043 system. Canna uses only grammar, but its grammar and dictionary are
|
|
|
1044 quite sophisticated. So for standard modern Japanese, Canna seems
|
|
|
1045 cleverer than Wnn4. In addition, the UNIX version of Canna is free (now
|
|
|
1046 there is a Microsoft Windows version).
|
|
|
1047
|
|
|
1048 SJ3, by Sony, supports only Japanese.
|
|
428
|
1049
|
|
|
1050 Egg consists of following parts:
|
|
|
1051
|
|
|
1052 @enumerate
|
|
|
1053 @item
|
|
|
1054 Input character Translation System (ITS) layer.

1055 It translates ASCII inputs to Kana/PinYin/Hangul characters.

|
428
|
1060 @end enumerate
|
|
|
1061
|
|
1135
|
1062 These input methods are modal. They have a raw (alphabet) mode, a
|
|
|
1063 phonetic input mode, and Kana-Kanji transfer mode. However there are
|
|
|
1064 mode-less input methods for Egg and Canna. @samp{boiled-egg} is a
|
|
|
1065 mode-less input method running on Egg. For Canna, @samp{canna.el} has a
|
|
|
1066 tiny boiled-egg-like command, @code{(canna-boil)}, and there are some
|
|
|
1067 boiled-egg-like utilities.

|
|
428
|
1074
|
|
1135
|
1075 MULE has evolved rapidly over the last few years, and the original third
|
|
|
1076 party patch (for GNU Emacs 19), GNU Emacs 20+, and XEmacs 20+ have quite
|
|
|
1077 different implementations. The APIs also vary although recent versions
|
|
|
1078 of XEmacs have tended to converge to the GNU Emacs standard.
|
|
|
1079
|
|
|
1080 MULE implementations are going to continue to evolve. Both GNU Emacs
|
|
|
1081 and XEmacs are working hard on Unicode support, which will involve new
|
|
|
1082 APIs and probably variations on old ones. For XEmacs 22, the old ISO
|
|
|
1083 2022-based system for recognizing encodings will be replaced by a much
|
|
|
1084 more flexible system, which should improve accuracy of automatic coding
|
|
|
1085 detections, but will also involve new APIs.

|
|
|
1177
|
|
|
1178 Partially, as an external encoding for files, processes, and terminals.
|
|
|
1179 It does not yet support Unicode fonts @ref{Q1.3.9, Does XEmacs support
|
|
|
1180 Unicode Fonts?}
|
|
|
1181
|
|
|
1182 To get Unicode support, you need a Mule-enabled XEmacs. Install
|
|
|
1183 Mule-UCS from packages in the usual way. Put
|
|
|
1184
|
|
1616
|
1185 @example
|
|
745
|
1186 (require 'un-define)
|
|
|
1187 (set-coding-priority-list '(utf-8))
|
|
1616
|
1188 (set-coding-category-system 'utf-8 'utf-8)
|
|
|
1189 @end example
|
|
|
1190
|
|
|
1191 in your init file to enable the UTF-8 coding system. You may wish to
|
|
|
1192 view the documentation of @code{set-coding-priority-list} if you find
|
|
|
1193 that files that are not UTF-8 are being mis-recognized as UTF-8.
|
|
745
|
1194
|
|
|
1195 Install standard national fonts (not Unicode fonts) for all
|
|
1616
|
1196 character sets you use. See @ref{Q1.3.9}.
|
|
745
|
1197
|
|
|
1198 Mule-UCS also supports 16-bit forms of Unicode (UTF-16). It does not
|
|
|
1199 support 31-bit forms of Unicode (UTF-32 or UCS-4).

1202 @unnumberedsubsec Q1.3.9: How does XEmacs display Unicode?
|
|
|
1203
|
|
|
1204 Mule doesn't have a Unicode charset internally, so there's nothing to
|
|
|
1205 bind a Unicode registry to. It would not be straightforward to create,
|
|
|
1206 either, because Unicode is not ISO 2022-compatible. You'd have to
|
|
|
1207 translate it to multiple 96x96 pages.
|
|
|
1208
|
|
|
1209 This means that Mule-UCS uses ordinary national fonts for display. This
|
|
|
1210 is not really a problem, except for those languages that use the Unified
|
|
|
1211 Han characters. The problem here is that Mule-UCS maps from Unicode
|
|
|
1212 code points to national character sets in a deterministic way. By
|
|
|
1213 default, this means that Japanese fonts are tried first, then Chinese,
|
|
|
1214 then Korean. To change the priority ordering, use the command
|
|
|
1215 `un-define-change-charset-order'.
|
|
|
1216
|
|
|
1217 It also means you can't use Unicode fonts directly, at least not without
|
|
|
1218 extreme hackery. You can run -nw with (set-terminal-coding-system
|
|
|
1219 'utf-8) if you really want a Unicode font for some reason.
|
|
|
1220
|
|
|
1221 Real Unicode support will be introduced in XEmacs 22.0.

|
1225 @unnumberedsubsec Q1.4.1: What is an @file{init.el} or @file{.emacs} and is there a sample one?
|
|
|
1226
|
|
|
1227 The @file{init.el} or @file{.emacs} file is used to customize XEmacs to
|
|
|
1228 your tastes. Starting in 21.4, the preferred location for the init file
|
|
|
1229 is @file{~/.xemacs/init.el}; in previous versions, it was
|
|
|
1230 @file{~/.emacs}. 21.4 still accepts the old location, but the first
|
|
|
1231 time you run it, it will ask to migrate your file to the new location.
|
|
|
1232 If you answer yes, the file will be moved, and a "compatibility"
|
|
|
1233 @file{.emacs} file will be placed in the old location so that you can
|
|
|
1234 still run older versions of XEmacs, and versions of GNU Emacs, which
|
|
|
1235 expect the old location. The @file{.emacs} file present is just a stub
|
|
|
1236 that loads the real file in @file{~/.xemacs/init.el}.
|
|
|
1237
|
|
|
1238 No two init files are alike, nor are they expected to be alike, but
|
|
|
1239 that's the point. The XEmacs distribution contains an excellent starter
|
|
|
1240 example in the @file{etc/} directory called @file{sample.init.el}
|
|
|
1241 (starting in 21.4) or @file{sample.emacs} in older versions. Copy this
|
|
|
1242 file from there to @file{~/.xemacs/init.el} (starting in 21.4) or
|
|
|
1243 @file{~/.emacs} in older versions, where @samp{~} means your home
|
|
|
1244 directory, of course. Then edit it to suit.
|
|
|
1245
|
|
|
1246 You may bring the @file{sample.init.el} or @file{sample.emacs} file into
|
|
|
1247 an XEmacs buffer from the menubar. (The menu entry for it is always
|
|
|
1248 under the @samp{Help} menu, but its location under that has changed in
|
|
|
1249 various versions. Recently, look under the @samp{Samples} submenu.) To
|
|
|
1250 determine the location of the @file{etc/} directory type the command
|
|
428
|
1251 @kbd{C-h v data-directory @key{RET}}.

|
|
|
1283
|
|

1284 The following function does a little bit of everything useful. It does
|
|
|
1285 something with the prefix argument, it examines the text around the
|
|
|
1286 cursor, and it's interactive so it may be bound to a key. It inserts
|
|
|
1287 copies of the current word the cursor is sitting on at the cursor. If
|
|
|
1288 you give it a prefix argument: @kbd{C-u 3 M-x double-word} then it will
|
|
|
1289 insert 3 copies.
|
|
|
1290
|
|
|
1291 @lisp
|
|
|
1292 (defun double-word (count)
|
|

1293 "Insert a copy of the current word underneath the cursor"
|

1294 (interactive "*p")
|

|
|
|
1305 @end lisp
|
|
|
1306
|
|
|
1307 The best way to see what is going on here is to let XEmacs tell you.
|
|
|
1308 Put the code into an XEmacs buffer, and do a @kbd{C-h f} with the cursor
|
|
|
1309 sitting just to the right of the function you want explained. Eg. move
|
|
|
1310 the cursor to the SPACE between @code{interactive} and @samp{"*p"} and
|
|
|
1311 hit @kbd{C-h f} to see what the function @code{interactive} does. Doing
|
|
|
1312 this will tell you that the @code{*} requires a writable buffer, and
|
|
|
1313 @code{p} converts the prefix argument to a number, and
|
|
|
1314 @code{interactive} allows you to execute the command with @kbd{M-x}.

1328 @unnumberedsubsec Q1.4.6: What's the difference between a macro and a function?
|
|
|
1329
|
|
|
1330 Quoting from the Lisp Reference (a.k.a @dfn{Lispref}) Manual:
|
|
|
1331
|
|
|
1332 @dfn{Macros} enable you to define new control constructs and other
|
|
|
1333 language features. A macro is defined much like a function, but instead
|
|
|
1334 of telling how to compute a value, it tells how to compute another Lisp
|
|
|
1335 expression which will in turn compute the value. We call this
|
|
|
1336 expression the @dfn{expansion} of the macro.
|
|
|
1337
|
|
|
1338 Macros can do this because they operate on the unevaluated expressions
|
|
|
1339 for the arguments, not on the argument values as functions do. They can
|
|
|
1340 therefore construct an expansion containing these argument expressions
|
|
|
1341 or parts of them.
|
|
|
1342
|
|
|
1343 Do not confuse the two terms with @dfn{keyboard macros}, which are
|
|
|
1344 another matter, entirely. A keyboard macro is a key bound to several
|
|
|
1345 other keys. Refer to manual for details.

1404 How can I just try XEmacs without installing it?
|
|
428
|
1405
|
|
|
1406 XEmacs will run in place without requiring installation and copying of
|
|
|
1407 the Lisp directories, and without having to specify a special build-time
|
|
|
1408 flag. It's the copying of the Lisp directories that requires so much
|
|
|
1409 space. XEmacs is largely written in Lisp.
|
|
|
1410
|
|
|
1411 A good method is to make a shell alias for xemacs:
|
|
|
1412
|
|
|
1413 @example
|
|
|
1414 alias xemacs=/i/xemacs-20.2/src/xemacs
|
|
|
1415 @end example
|
|
|
1416
|
|
|
1417 (You will obviously use whatever directory you downloaded the source
|
|
|
1418 tree to instead of @file{/i/xemacs-20.2}).
|
|
|
1419
|
|
|
1420 This will let you run XEmacs without massive copying.

1424
|
|
442
|
1425 The space required by the installation directories can be
|
|
428
|
1426 reduced dramatically if desired. Gzip all the .el files. Remove all
|
|
442
|
1427 the packages you'll never want to use. Remove the TexInfo manuals.
|
|
428
|
1428 Remove the Info (and use just hardcopy versions of the manual). Remove
|
|
|
1429 most of the stuff in etc. Remove or gzip all the source code. Gzip or
|
|
|
1430 remove the C source code. Configure it so that copies are not made of
|
|
1138
|
1431 the support lisp.
|
|
428
|
1432
|
|
|
1433 These are all Emacs Lisp source code and bytecompiled object code. You
|
|
|
1434 may safely gzip everything named *.el here. You may remove any package
|
|
|
1435 you don't use. @emph{Nothing bad will happen if you delete a package
|
|
|
1436 that you do not use}. You must be sure you do not use it though, so be
|
|
|
1437 conservative at first.
|
|
|
1438
|
|
1648
|
1439 Any package with the possible exceptions of xemacs-base, and EFS are
|
|
|
1440 candidates for removal. Ask yourself, @emph{Do I ever want to use this
|
|
|
1441 package?} If the answer is no, then it is a candidate for removal.
|
|
428
|
1442
|
|
|
1443 First, gzip all the .el files. Then go about package by package and
|
|
|
1444 start gzipping the .elc files. Then run XEmacs and do whatever it is
|
|
1648
|
1445 you normally do. If nothing bad happens, then remove the package. You
|
|
|
1446 can remove a package via the PUI interface
|
|
|
1447 (@code{M-x pui-list-packages}, then press @kbd{d} to mark the packages
|
|
|
1448 you wish to delete, and then @kbd{x} to delete them.

1453 @unnumberedsubsec Q2.0.3: Compiling XEmacs with Netaudio.
|
|
|
1454
|
|
|
1455 What is the best way to compile XEmacs with the netaudio system, since I
|
|
|
1456 have got the netaudio system compiled but installed at a weird place, I
|
|
|
1457 am not root. Also in the READMEs it does not say anything about
|
|
|
1458 compiling with the audioserver?
|
|
|
1459
|
|
|
1460 You should only need to add some stuff to the configure command line.
|
|
|
1461 To tell it to compile in netaudio support: @samp{--with-sound=both}, or
|
|
|
1462 @samp{--with-sound=nas} if you don't want native sound support for some
|
|
|
1463 reason.) To tell it where to find the netaudio includes and libraries:
|
|
|
1464
|
|
|
1465 @example
|
|
|
1466 --site-libraries=WHATEVER
|
|
|
1467 --site-includes=WHATEVER
|
|
|
1468 @end example
|
|
|
1469
|
|
|
1470 Then (fingers crossed) it should compile and it will use netaudio if you
|
|
|
1471 have a server running corresponding to the X server. The netaudio server
|
|
|
1472 has to be there when XEmacs starts. If the netaudio server goes away and
|
|
|
1473 another is run, XEmacs should cope (fingers crossed, error handling in
|
|
|
1474 netaudio isn't perfect).
|
|
|
1475
|
|
|
1476 BTW, netaudio has been renamed as it has a name clash with something
|
|
|
1477 else, so if you see references to NAS or Network Audio System, it's the
|
|
|
1478 same thing. It also might be found at

1670 That's correct [The SunOS 4.1.3 precompiled binaries don't do name

|

1672 (that DNS thing was apparently only a passing fad, right?), the stock

1688 Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
|
|
|
1689 link gives you a bare-boned emacs (called temacs). temacs is then run,
|
|
|
1690 preloading some of the lisp files. The result is then dumped into a new
|
|
|
1691 executable, named xemacs, which will contain all of the preloaded lisp
|
|
|
1692 functions and data.
|
|
|
1693
|
|
|
1694 Now, during the dump itself, the executable (code+data+symbols) is
|
|
|
1695 written on disk using a special unexec() function. This function is
|
|
|
1696 obviously heavily system dependent. And on some systems, it leads to an
|
|
|
1697 executable which, although valid, cannot be stripped without damage. If
|
|
|
1698 memory serves, this is especially the case for AIX binaries. On other
|
|
462
|
1699 architectures it might work OK.
|
|
428
|
1700
|
|
|
1701 The Right Way to strip the emacs binary is to strip temacs prior to
|
|
|
1702 dumping xemacs. This will always work, although you can do that only if
|
|
|
1703 you install from sources (as temacs is @file{not} part of the binary
|
|
|
1704 kits).

|
1782
|

1783 and notes that you need to add an element (often "-u") to

|
|
1785 needed flag with `man ftp' or other local documentation.

1789

1790 The Cygwin binary distributed with the netinstaller uses an external DLL
|

1792

1793 This application has failed to start because cygXpm-noX4.dll was not found.

1798 cygXpm-noX4 is part of the cygwin distribution under libraries or

1806 @unnumberedsec 2.1: Trouble Shooting
|
|
|
1807 @unnumberedsubsec Q2.1.1: Help! XEmacs just crashed on me!
|
|
|
1808
|
|
|
1809 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
|
1810 hard to auto-save all of your files before dying. (The main time that
|
|
|
1811 this will not happen is if the machine physically lost power or if you
|
|
|
1812 killed the XEmacs process using @code{kill -9}). The next time you try
|
|
|
1813 to edit those files, you will be informed that a more recent auto-save
|
|
|
1814 file exists. You can use @kbd{M-x recover-file} to retrieve the
|
|
|
1815 auto-saved version of the file.
|
|
|
1816
|
|
462
|
1817 You can use the command @kbd{M-x recover-session} after a crash to pick
|
|
|
1818 up where you left off.
|
|
428
|
1819
|
|
|
1820 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
1821 particular sequences of actions, that cause it to crash. If you can
|
|
|
1822 come up with a reproducible way of doing this (or even if you have a
|
|
|
1823 pretty good memory of exactly what you were doing at the time), the
|
|
1183
|
1824 maintainers would be very interested in knowing about it. The best way
|
|
|
1825 to report a bug is using @kbd{M-x report-emacs-bug} (or by selecting
|
|
|
1826 @samp{Send Bug Report...} from the Help menu). If that won't work
|
|
|
1827 (e.g. you can't get XEmacs working at all), send ordinary mail to
|
|
|
1828 @email{crashes@@xemacs.org}. @emph{MAKE SURE} to include the output from
|
|
|
1829 the crash, especially including the Lisp backtrace, as well as the
|
|
|
1830 XEmacs configuration from @kbd{M-x describe-installation} (or
|
|
|
1831 equivalently, the file @file{Installation} in the top of the build
|
|
|
1832 tree). Please note that the @samp{crashes} address is exclusively for
|
|
|
1833 crash reports. The best way to report bugs in general is through the
|
|
|
1834 @kbd{M-x report-emacs-bug} interface just mentioned, or if necessary by
|
|
|
1835 emailing @email{xemacs-beta@@xemacs.org}. Note that the developers do
|
|
|
1836 @emph{not} usually follow @samp{comp.emacs.xemacs} on a regular basis;
|
|
|
1837 thus, this is better for general questions about XEmacs than bug
|
|
428
|
1838 reports.
|
|
|
1839
|
|
1183
|
1840 If at all possible, include a C stack backtrace of the core dump that
|
|
|
1841 was produced. This shows where exactly things went wrong, and makes it
|
|
|
1842 much easier to diagnose problems. To do this under Unix, you need to
|
|
|
1843 locate the core file (it's called @file{core}, and is usually sitting in
|
|
|
1844 the directory that you started XEmacs from, or your home directory if
|
|
|
1845 that other directory was not writable). Then, go to that directory and
|
|
|
1846 execute a command like:
|
|
428
|
1847
|
|
|
1848 @example
|
|
|
1849 gdb `which xemacs` core
|
|
|
1850 @end example
|
|
|
1851
|
|
|
1852 and then issue the command @samp{where} to get the stack backtrace. You
|
|
|
1853 might have to use @code{dbx} or some similar debugger in place of
|
|
|
1854 @code{gdb}. If you don't have any such debugger available, complain to
|
|
|
1855 your system administrator.
|
|
|
1856
|
|
|
1857 It's possible that a core file didn't get produced, in which case you're
|
|
|
1858 out of luck. Go complain to your system administrator and tell him not
|
|
593
|
1859 to disable core files by default. Also see @ref{Q2.1.15}, for tips and
|
|
428
|
1860 techniques for dealing with a debugger.
|
|
|
1861
|
|
1183
|
1862 If you're under Microsoft Windows, you're out of luck unless you happen
|
|
|
1863 to have a debugging aid installed on your system, for example Visual
|
|
|
1864 C++. In this case, the crash will result in a message giving you the
|
|
|
1865 option to enter a debugger (for example, by pressing @samp{Cancel}). Do
|
|
|
1866 this and locate the stack-trace window. (If your XEmacs was built
|
|
|
1867 without debugging information, the stack trace may not be very useful.)

|

1936 How do I get rid of them?
|
|

1937
|
|
|
1938 There are two causes of this problem. The first usually only strikes
|
|
|
1939 people using the prebuilt binaries. The culprit in both cases is the
|
|
|
1940 file @file{XKeysymDB}.
|
|
|
1941
|
|
|
1942 @itemize @bullet
|
|
|
1943 @item
|
|
|
1944 The binary cannot find the @file{XKeysymDB} file. The location is
|
|
|
1945 hardcoded at compile time so if the system the binary was built on puts
|
|
|
1946 it a different place than your system does, you have problems. To fix,
|
|
1738
|
1947 set the environment variable @code{XKEYSYMDB} to the location of the
|
|
428
|
1948 @file{XKeysymDB} file on your system or to the location of the one
|
|
|
1949 included with XEmacs which should be at
|
|
|
1950 @iftex
|
|
|
1951 @*
|
|

1952 @end iftex

1954
|
|

1955 @item
|
|
|
1956 The binary is finding the XKeysymDB but it is out-of-date on your system
|
|
|
1957 and does not contain the necessary lines. Either ask your system
|
|
|
1958 administrator to replace it with the one which comes with XEmacs (which
|
|
|
1959 is the stock R6 version and is backwards compatible) or set your

1967
|

1968 This is highly dependent on your installation, but try with the

|
|
|
1970
|
|
|
1971 @format

1972 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|

|
|
|
1974
|
|
|
1975 More precisely, do the following in your resource file:
|
|
|
1976
|
|
|
1977 @format
|
|
|
1978 Emacs.default.attributeFont: \

|

1980 @end format
|
|
|
1981
|
|
|
1982 If you just don't want to see the @samp{*Warnings*} buffer at startup
|

|
1983 time, you can set this:
|
|
|
1984

1986 (setq display-warning-minimum-level 'error)

2077 replace it with one from the generic MIT X11 release. You might also

2230 @unnumberedsubsec Q2.1.15: How to debug an XEmacs problem with a debugger
|
|
428
|
2231
|
|
|
2232 If XEmacs does crash on you, one of the most productive things you can
|
|
|
2233 do to help get the bug fixed is to poke around a bit with the debugger.
|
|
|
2234 Here are some hints:
|
|
|
2235
|
|
|
2236 @itemize @bullet
|
|
|
2237 @item
|
|
|
2238 First of all, if the crash is at all reproducible, consider very
|
|
563
|
2239 strongly recompiling your XEmacs with debugging symbols and with no
|
|
|
2240 optimization (e.g. with GCC use the compiler flags @samp{-g -O0} --
|
|
|
2241 that's an "oh" followed by a zero), and with the configure options
|
|
|
2242 @samp{--debug=yes} and @samp{--error-checking=all}. This will make your
|
|
1258
|
2243 XEmacs run somewhat slower, but you are a lot more likely to catch the
|
|
|
2244 problem earlier (closer to its source). It makes it a lot easier to
|
|
|
2245 determine what's going on with a debugger.
|
|
|
2246
|
|
|
2247 @item
|
|
|
2248 If it's not a true crash (@emph{i.e.}, XEmacs is hung, or a zombie
|
|
|
2249 process), or it's inconvenient to run XEmacs again because XEmacs is
|
|
|
2250 already running or is running in batch mode as part of a bunch of
|
|
|
2251 scripts, you may be able to attach to the existing process with your
|
|
|
2252 debugger. Most debuggers let you do this by substituting the process ID
|
|
|
2253 for the core file when you invoke the debugger from the command line, or
|
|
|
2254 by using the @code{attach} command or something similar.
|
|
|
2255
|
|
|
2256 @item
|
|
|
2257 If you're able to run XEmacs under a debugger and reproduce the crash,
|
|
|
2258 here are some things you can do:
|
|
428
|
2259
|
|
|
2260 @item
|
|
|
2261 If XEmacs is hitting an assertion failure, put a breakpoint on
|
|
|
2262 @code{assert_failed()}.
|
|
|
2263
|
|
|
2264 @item
|
|
|
2265 If XEmacs is hitting some weird Lisp error that's causing it to crash
|
|
|
2266 (e.g. during startup), put a breakpoint on @code{signal_1()}---this is
|
|
|
2267 declared static in eval.c.
|
|
|
2268
|
|
|
2269 @item
|
|
563
|
2270 If XEmacs is outputting lots of X errors, put a breakpoint on
|
|
|
2271 @code{x_error_handler()}; that will tell you which call is causing them.
|
|
|
2272
|
|
|
2273 @item
|
|
428
|
2274 Internally, you will probably see lots of variables that hold objects of
|
|
1258
|
2275 type @code{Lisp_Object}. These are references to Lisp objects.
|
|
|
2276 Printing them out with the debugger probably won't be too
|
|
|
2277 useful---you'll likely just see a number. To decode them, do this:
|
|
428
|
2278
|
|
|
2279 @example
|
|
1183
|
2280 call dp (OBJECT)
|
|
428
|
2281 @end example
|
|
|
2282
|
|
|
2283 where @var{OBJECT} is whatever you want to decode (it can be a variable,
|
|
1258
|
2284 a function call, etc.). This uses the Lisp printing routines to out a
|
|
|
2285 readable representation on the TTY from which the xemacs process was
|
|
|
2286 invoked.
|
|
428
|
2287
|
|
|
2288 @item
|
|
|
2289 If you want to get a Lisp backtrace showing the Lisp call
|
|
|
2290 stack, do this:
|
|
|
2291
|
|
|
2292 @example
|
|
1183
|
2293 call db ()
|
|
428
|
2294 @end example
|
|
|
2295
|
|
|
2296 @item
|
|
1258
|
2297 Using @code{dp} and @code{db} has two disadvantages - they can only be
|
|
|
2298 used with a running (including hung or zombie) xemacs process, and they
|
|
|
2299 do not display the internal C structure of a Lisp Object. Even if all
|
|
|
2300 you've got is a core dump, all is not lost.
|
|
428
|
2301
|
|
|
2302 If you're using GDB, there are some macros in the file
|
|
438
|
2303 @file{src/.gdbinit} in the XEmacs source distribution that should make
|
|
|
2304 it easier for you to decode Lisp objects. This file is automatically
|
|
|
2305 read by gdb if gdb is run in the directory where xemacs was built, and
|
|
|
2306 contains these useful macros to inspect the state of xemacs:

2356 If you're using a debugger to get a C stack backtrace and you're seeing

2357 stack traces with some of the innermost frames mangled, it may be due to
|
|
|
2358 dynamic linking. (This happens especially under Linux.) Consider
|
|
|
2359 reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
|
|
|
2360 Linux), stack backtraces of core dumps will have the frame where the
|
|
|
2361 fatal signal occurred mangled; if you can obtain a stack trace while
|
|
|
2362 running the XEmacs process under a debugger, the stack trace should be
|
|
|
2363 clean.

2369 If you're using a debugger to get a C stack backtrace and you're

2378

2379 @item

2380 Your stack is getting trashed. Debugging this is hard; you have to do a
|
|
|
2381 binary-search type of narrowing down where the crash occurs, until you
|
|
|
2382 figure out exactly which line is causing the problem. Of course, this
|
|
1258
|
2383 only works if the bug is highly reproducible. Also, in many cases if
|
|
|
2384 you run XEmacs from the debugger, the debugger can protect the stack
|
|
|
2385 somewhat. However, if the stack is being smashed, it is typically the
|
|
|
2386 case that there is a wild pointer somewhere in the program, often quite
|

2390 If your stack trace has exactly one frame in it, with address 0x0, this
|
|
|
2391 could simply mean that XEmacs attempted to execute code at that address,
|
|
|
2392 e.g. through jumping to a null function pointer. Unfortunately, under
|
|
|
2393 those circumstances, GDB under Linux doesn't know how to get a stack
|
|
1183
|
2394 trace. (Yes, this is the fourth Linux-related problem I've mentioned. I

2395 have no idea why GDB under Linux is so bogus. Complain to the GDB

2503 Two things you can do:
|
|
|
2504
|
|
|
2505 1) C level:
|
|
|
2506
|
|
|
2507 When you see it going mad like this, you might want to use gdb from an
|
|
|
2508 'xterm' to attach to the running process and get a stack trace. To do
|
|
|
2509 this just run:
|
|
|
2510
|
|
|
2511 @example
|
|
|
2512 gdb /path/to/xemacs/xemacs ####
|
|
|
2513 @end example
|
|
|
2514
|
|
|
2515 Where @code{####} is the process id of your xemacs, instead of
|
|
|
2516 specifying the core. When gdb attaches, the xemacs will stop [1] and
|
|
|
2517 you can type `where' in gdb to get a stack trace as usual. To get
|
|
|
2518 things moving again, you can just type `quit' in gdb. It'll tell you
|
|
|
2519 the program is running and ask if you want to quit anyways. Say 'y' and
|
|
|
2520 it'll quit and have your emacs continue from where it was at.
|
|
|
2521
|
|
|
2522 2) Lisp level:
|
|
|
2523
|
|
|
2524 Turn on debug-on-quit early on. When you think things are going slow
|
|
|
2525 hit C-g and it may pop you in the debugger so you can see what routine
|
|
|
2526 is running. Press `c' to get going again.
|
|
|
2527
|
|
|
2528 debug-on-quit doesn't work if something's turned on inhibit-quit or in
|
|
|
2529 some other strange cases.

2554 If XEmacs starts when you're on the network, but fails when you're not

2847 installation in your @file{~/.Xresources} file. It is nearly the same

2848 as @file{etc/Emacs.ad}, but a few entries are altered. Be careful about

|

2849 installing the contents of this file into your @file{.Xresources} (or

2907 @unnumberedsubsec Q3.1.7: @samp{xemacs -name junk} doesn't work?
|
|
|
2908
|
|
|
2909 When I run @samp{xterm -name junk}, I get an xterm whose class name
|
|
|
2910 according to xprop, is @samp{junk}. This is the way it's supposed to
|
|
|
2911 work, I think. When I run @samp{xemacs -name junk} the class name is
|
|
|
2912 not set to @samp{junk}. It's still @samp{emacs}. What does
|
|
|
2913 @samp{xemacs -name} really do? The reason I ask is that my window
|
|
|
2914 manager (fvwm) will make a window sticky and I use XEmacs to read my
|
|
|
2915 mail. I want that XEmacs window to be sticky, without having to use the
|
|
|
2916 window manager's function to set the window sticky. What gives?
|
|
|
2917
|
|
|
2918 @samp{xemacs -name} sets the application name for the program (that is,
|
|
|
2919 the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
|
|
|
2920 is the same as making a copy of the executable with that new name. The
|
|
|
2921 @code{WM_CLASS} property on each frame is set to the frame-name, and the
|
|
|
2922 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
2923 created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
|
|
|
2924 @code{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
2925 widget would be:
|
|
|
2926
|
|
|
2927 @example
|
|
|
2928 Name: FOO .shell .container .BAR
|
|
|
2929 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2930 @end example
|
|
|
2931
|
|
|
2932 instead of the default
|
|
|
2933
|
|
|
2934 @example
|
|
|
2935 Name: xemacs.shell .container .emacs
|
|
|
2936 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2937 @end example
|
|
|
2938
|
|
|
2939
|
|
|
2940 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
2941 application-name instead of the frame-name, but I think that's less
|
|
|
2942 flexible, since it does not give you the ability to have multiple frames
|
|
|
2943 with different WM_CLASS properties. Another possibility would be for
|
|
|
2944 the default frame name to come from the application name instead of
|
|
|
2945 simply being @samp{emacs}. However, at this point, making that change
|
|
|
2946 would be troublesome: it would mean that many users would have to make
|
|
|
2947 yet another change to their resource files (since the default frame name
|
|
|
2948 would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
|
|
|
2949 the executable happened to be named), so we'd rather avoid it.
|
|
|
2950
|
|
|
2951 To make a frame with a particular name use:
|
|
|
2952
|
|
|
2953 @lisp

3007

3008 Note that you should use @samp{Emacs.} and not @samp{Emacs*} when

3009 setting face values.
|

|
|
|
3017 @end example
|
|
|
3018
|
|
1389
|
3019 This is confusing because @samp{default} and @samp{modeline} are face
|
|
|
3020 names, and can be found listed with all faces in the current mode by
|
|
|
3021 using @kbd{M-x set-face-font (enter) ?}. They use the face-specific
|
|
1549
|
3022 resource @samp{attributeFont}.
|
|
1389
|
3023
|
|
|
3024 On the other hand, @samp{menubar} is a normal X thing that uses the
|
|
|
3025 resource @samp{font}. With Motif it @emph{may be} necessary to use
|
|
|
3026 @samp{fontList} @emph{instead of} @samp{font}. In @emph{non-Motif}
|
|
|
3027 configurations with Mule it @emph{is} necessary to use @samp{fontSet}
|

3028 instead of @samp{font}. (Sorry, there just is no simple recipe here.)

|
3053
|

3054 I'm using Netscape (or another color grabber like XEmacs);
|
|
462
|
3055 is there any way to limit the number of available colors in the color map?
|
|
|
3056
|
|
|
3057 Answer: No, but you can start Netscape before XEmacs, and it will use
|
|
|
3058 the closest available color if the colormap is full. You can also limit
|
|
|
3059 the number of colors Netscape uses, using the flags -mono, -ncols <#> or
|
|
|
3060 -install (for mono, limiting to <#> colors, or for using a private color
|
|
|
3061 map).
|
|
428
|
3062
|
|
|
3063 If you have the money, another solution would be to use a truecolor or
|
|
|
3064 direct color video.

3084 There are several ways to do it. For example, you could specify a
|
|
|
3085 default pixmap image to use in your @file{~/.Xresources}, e.g.,
|
|
|
3086
|

|
|
|
3092
|
|
|
3093 and then reload ~/.Xresources and restart XEmacs. Alternatively,
|
|
|
3094 since each face can have its own pixmap background, a better way
|
|
|
3095 would be to set a face's pixmap within your XEmacs init file, e.g.,
|
|
|
3096
|
|
|
3097 @lisp
|
|
|
3098 (set-face-background-pixmap 'default "/path/to/image.xpm")

3110 If you're using a Mule-enabled XEmacs, then display is automatic. If

3111 you're not seeing the characters you expect, either (1) you don't have
|
|

3112 appropriate fonts available or (2) XEmacs did not correctly detect the

|
3113 coding system (@pxref{Recognize Coding, , , xemacs}). In case (1),
|

3114 install fonts as is customary for your platform. In case (2), you

3232 Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline

462

3233 colors change from the default set in your @file{init.el}/@file{.emacs}.
|
|
|
3234 The change will only be made in the buffer you just entered (which

3235 contains the Lisp file you are editing) and will not affect the modeline
|
|
|
3236 colors anywhere else.

3278 Yes. Use @code{gnuclient -nw}. (Prior to 20.3, use the @code{gnuattach}
|
|
|
3279 program supplied with XEmacs instead.)

|
|
3285 @unnumberedsubsec Q3.5.1: How can I bind complex functions (or macros) to keys?
|
|
|
3286
|
|
|
3287 As an example, say you want the @kbd{paste} key on a Sun keyboard to
|
|
|
3288 insert the current Primary X selection at point. You can accomplish this
|
|
|
3289 with:
|
|
|
3290
|
|
|
3291 @lisp
|
|
|
3292 (define-key global-map [f18] 'x-insert-selection)
|
|
|
3293 @end lisp
|
|
|
3294
|
|
|
3295 However, this only works if there is a current X selection (the
|
|
|
3296 selection will be highlighted). The functionality I like is for the
|
|
|
3297 @kbd{paste} key to insert the current X selection if there is one,
|
|
|
3298 otherwise insert the contents of the clipboard. To do this you need to
|
|
|
3299 pass arguments to @code{x-insert-selection}. This is done by wrapping
|
|
|
3300 the call in a 'lambda form:
|
|
|
3301
|
|
|
3302 @lisp
|
|
|
3303 (global-set-key [f18]
|
|
|
3304 (lambda () (interactive) (x-insert-selection t nil)))
|
|
|
3305 @end lisp
|
|
|
3306
|
|
|
3307 This binds the f18 key to a @dfn{generic} functional object. The
|
|
|
3308 interactive spec is required because only interactive functions can be
|
|
|
3309 bound to keys.
|
|
|
3310
|
|
|
3311 For the FAQ example you could use:
|
|
|
3312
|
|
|
3313 @lisp
|
|
|
3314 (global-set-key [(control ?.)]
|
|
|
3315 (lambda () (interactive) (scroll-up 1)))
|
|
440
|
3316 (global-set-key [(control ?;)]
|
|
|
3317 (lambda () (interactive) (scroll-up -1)))
|
|
428
|
3318 @end lisp
|
|
|
3319
|
|
|
3320 This is fine if you only need a few functions within the lambda body.
|
|
|
3321 If you're doing more it's cleaner to define a separate function as in
|
|
|
3322 question 3.5.3 (@pxref{Q3.5.3}).

3353

3354 The key point is that you can only bind simple functions to keys; you

3355 can not bind a key to a function that you're also passing arguments to.

3360
|
|

3361 I cannot manage to globally bind my @kbd{Delete} key to something other

|

|
|

3383
|
|

3384 Try this:

3385
|
|
|
3386 @lisp
|

3389 (interactive "p")

|
|
|
3391

|
|
|
3399 @end lisp
|
|
|
3400
|
|
|
3401 The following will also work but will affect more than just the cursor
|
|
|
3402 keys (i.e. @kbd{C-n} and @kbd{C-p}):
|
|
|
3403

3428 But it doesn't work alone. This is in the file @file{PROBLEMS} which

|
|

|

3438 events is a security hole, so this is turned off by default. You can
|
|
|
3439 enable it by setting the variable @code{x-allow-sendevents} to t. You
|
|
|
3440 can also cause fix this by telling OLWM to not grab the help key, with
|

3441 the null binding @code{OpenWindows.KeyboardCommand.Help:}.

3455 It depends upon your X server.
|
|
|
3456
|
|
|
3457 Generally, the simplest way is to define a key as Multi_key with
|
|
|
3458 xmodmap, e.g.
|
|
|
3459 @c hey, show some respect, willya -- there's xkeycaps, isn't there? --
|
|
|
3460 @c chr ;)
|
|
|
3461 @example
|
|
440
|
3462 xmodmap -e 'keycode 0xff20 = Multi_key'
|
|
428
|
3463 @end example
|
|
|
3464
|
|
|
3465 You will need to pick an appropriate keycode. Use xev to find out the
|
|
|
3466 keycodes for each key.
|
|
|
3467
|
|
|
3468 [NB: On a `Windows' keyboard, recent versions of XFree86 automatically
|
|
|
3469 define the right `Windows' key as Multi_key'.]
|
|
|
3470
|
|
|
3471 Once you have Multi_key defined, you can use e.g.
|
|
|
3472 @example
|
|
440
|
3473 Multi a ' => á
|
|
|
3474 Multi e " => ë
|
|
|
3475 Multi c , => ç
|
|
428
|
3476 @end example
|
|
|
3477
|
|
|
3478 etc.
|
|
|
3479
|
|
|
3480 Also, recent versions of XFree86 define various AltGr-<key>
|
|
|
3481 combinations as dead keys, i.e.
|
|
|
3482 @example
|
|
440
|
3483 AltGr [ => dead_diaeresis
|
|
|
3484 AltGr ] => dead_tilde
|
|
|
3485 AltGr ; => dead_acute
|
|
428
|
3486 @end example
|
|
|
3487 etc.
|
|
|
3488
|
|
|
3489 Running @samp{xmodmap -pk} will list all of the defined keysyms.

|
|
|
3502
|
|

3503 With XEmacs-20.2 use the @code{delbs} package:

|
3504
|

3505 @lisp
|
|
|
3506 (require 'delbs)
|
|

|
|
|
3508
|
|
|
3509 This will give you the functions @code{delbs-enable-delete-forward} to
|
|
|
3510 set things up, and @code{delbs-disable-delete-forward} to revert to
|
|
|
3511 ``normal'' behavior. Note that @code{delbackspace} package is obsolete.
|
|
|
3512
|
|
|
3513 Starting with XEmacs-20.3 better solution is to set variable
|
|
|
3514 @code{delete-key-deletes-forward} to t. You can also change this with
|
|
|
3515 Customize. Select from the @code{Options} menu

3789
|

1386

3790 In Motif, the use of @samp{font} resources is obsoleted in order to

3791 support internationalization. If you are using the real Motif menubar,
|
|
|
3792 this resource is not recognized at all; you have to say:

428

3793
|
|

3794 @example

3795 Emacs*menubar*fontList: FONT

|
|
|
3797
|
|
1389
|
3798 If you are using the Lucid menubar, for backward compatibility with
|
|
|
3799 existing user configurations, the @samp{font} resource is recognized.
|
|
|
3800 Since this is not supported by Motif itself, the code is a kludge and
|
|
|
3801 the @samp{font} resource will be recognized only if the @samp{fontList}
|
|
|
3802 resource resource is unset. This means that the resource
|
|
428
|
3803
|
|
|
3804 @example
|

3814 even though the latter is more specific.

1389
|
3816 In non-Motif configurations using @samp{--with-mule} and
|
|
|
3817 @samp{--with-xfs} it @emph{is} necessary to use the @code{fontSet}
|

3818 resource @emph{instead of} the @code{font} resource. The backward

3904 When I move the scrollbar in an XEmacs window, it moves the point as
|
|
|
3905 well, which should not be the default behavior. Is this a bug or a
|
|
|
3906 feature? Can I disable it?
|
|
|
3907
|
|
|
3908 The current behavior is a feature, not a bug. Point remains at the same
|
|
|
3909 buffer position as long as that position does not scroll off the screen.
|
|
|
3910 In that event, point will end up in either the upper-left or lower-left
|
|
|
3911 hand corner.
|
|
|
3912
|
|
|
3913 This cannot be changed.

|

3921 More precisely: If @code{truncate-lines} is nil, horizontal scrollbars

3922 will never appear. Otherwise, they will appear only if the value of
|
|
|
3923 @code{scrollbar-height} for that buffer/window/etc. is non-zero. If you

|

3936
|
|

3937 The @code{zmacs} mode allows for what some might call gratuitous
|
|
|
3938 highlighting for selected regions (either by setting mark or by using
|
|
|
3939 the mouse). This is the default behavior. To turn off, add the
|
|
462
|
3940 following line to your @file{init.el}/@file{.emacs} file:
|
|
428
|
3941

462
|
3947 from the @code{Options} menu @code{Advanced (Customize)->Emacs->Editing->Basics->Zmacs

428

3948 Regions} or type @kbd{M-x customize @key{RET} editing-basics @key{RET}}.
|

|
|
|
3955
|
|
|
3956 I want to change things so that if I select some text and start typing,
|
|
|
3957 the typed text replaces the selected text, similar to Motif.
|
|
|
3958
|
|
|
3959 You want to use something called @dfn{pending delete}. Pending delete
|
|
|
3960 is what happens when you select a region (with the mouse or keyboard)
|
|
|
3961 and you press a key to replace the selected region by the key you typed.
|
|
|
3962 Usually backspace kills the selected region.
|
|
|
3963
|
|
462
|
3964 To get this behavior, add the following lines to your @file{init.el}/@file{.emacs}:
|
|
428
|
3965
|
|
|
3966 @lisp
|
|
438
|
3967 (cond

428
|
3972 @end lisp
|
|
|
3973
|

1138
|
3974 Note that this will work with both Backspace and Delete. This code is a
|
|
438
|
3975 tad more complicated than it has to be for XEmacs in order to make it
|
|
|
3976 more portable.

|
|
|
3992

4042 @unnumberedsubsec Q3.10.6: Why is killing so slow?
|
|
|
4043
|
|
|
4044 This actually is an X Windows question, although you'll notice it with
|
|
|
4045 keyboard operations as well as while using the GUI. Basically, there
|
|
|
4046 are four ways to communicate interprogram via the X server:
|
|
|
4047
|
|
|
4048 @table @strong
|
|
|
4049 @item Primary selection
|
|
|
4050 a transient selection that gets replaced every time a new selection is made
|
|
|
4051
|
|
|
4052 @item Secondary selection
|
|
|
4053 for "exchanging" with the primary selection
|
|
|
4054
|
|
|
4055 @item Cut buffers
|
|
|
4056 a clipboard internal to the X server (deprecated)
|
|
|
4057
|
|
|
4058 @item Clipboard selection
|
|
|
4059 a selection with a notification protocol that allows a separate app to
|
|
|
4060 manage the clipboard
|
|
|
4061 @end table
|
|
|
4062
|
|
|
4063 The cut buffers are deprecated because managing them is even more
|
|
|
4064 inefficient than the clipboard notification protocol. The primary
|
|
|
4065 selection works fine for many users and applications, but is not very
|
|
|
4066 robust under intensive or sophisticated use.
|
|
|
4067
|
|
|
4068 In Motif and MS Windows, a clipboard has become the primary means for
|
|
|
4069 managing cut and paste. These means that "modern" applications tend to
|
|
|
4070 be oriented toward a true clipboard, rather than the primary selection.
|
|
|
4071 (On Windows, there is nothing equivalent to the primary selection.)
|
|
|
4072 It's not that XEmacs doesn't support the simple primary selection
|
|
|
4073 method, it's that more and more other applications don't.
|
|
|
4074
|
|
|
4075 So the slowdown occurs because XEmacs now engages in the clipboard
|
|
|
4076 notification protocol on @emph{every} kill. This is especially slow on
|
|
|
4077 Motif.
|
|
|
4078
|
|
|
4079 With most people running most clients and server on the same host, and
|
|
|
4080 many of the rest working over very fast communication, you may expect
|
|
|
4081 that the situation is not going to improve.
|
|
|
4082
|
|
|
4083 There are a number of workarounds. The most effective is to use a
|
|
|
4084 special command to do selection ownership only when you intend to paste
|
|
|
4085 to another application. Useful commands are @code{kill-primary-selection}
|
|
|
4086 and @code{copy-primary-selection}. These work only on text selected
|
|
|
4087 with the mouse (probably; experiment), and are bound by default to the
|
|
|
4088 @kbd{Cut} and @kbd{Copy}, respectively, buttons on the toolbar.
|
|
|
4089 @code{copy-primary-selection} is also bound to @kbd{C-Insert}. You can
|
|
|
4090 yank the clipboard contents with @code{yank-primary-selection}, bound to
|
|
|
4091 the @kbd{Paste} toolbar button and @kbd{Sh-Insert}.
|
|
|
4092
|
|
|
4093 If you are communicating by cut and paste with applications that use the
|
|
|
4094 primary selection, then you can customize
|
|
|
4095 @code{interprogram-cut-function} to @code{nil}, restoring the XEmacs
|
|
|
4096 version 20 behavior. How can you tell if a program will support this?
|
|
|
4097 Motifly-correct programs require the clipboard; you lose. For others,
|
|
|
4098 only by trying it. You also need to customize the complementary
|
|
|
4099 @code{interprogram-paste-function} to @code{nil}. (Otherwise
|
|
|
4100 XEmacs-to-XEmacs pastes will not work correctly.)
|
|
|
4101
|
|
|
4102 You may get some relief on Motif by setting
|
|
|
4103 @code{x-selection-strict-motif-ownership} to nil, but this means you will
|
|
|
4104 only intermittently be able to paste XEmacs kills to Motif applications.
|
|
|
4105
|
|
|

|
|
|
4284
|
|

4285 @quotation
|
|
|
4286 rmail and VM get new mail from @file{/usr/spool/mail/$USER} using a
|
|
|
4287 program called @code{movemail}. This program interlocks with
|
|
|
4288 @code{/bin/mail} using the protocol defined by @code{/bin/mail}.
|
|
|
4289
|
|
|
4290 There are two different protocols in general use. One of them uses the
|
|
|
4291 @code{flock} system call. The other involves creating a lock file;
|
|
|
4292 @code{movemail} must be able to write in @file{/usr/spool/mail} in order
|
|
|
4293 to do this. You control which one is used by defining, or not defining,
|
|
|
4294 the macro @code{MAIL_USE_FLOCK} in @file{config.h} or the m- or s- file
|
|
|
4295 it includes.
|
|
|
4296
|
|
|
4297 @strong{IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
|
|
|
4298 SYSTEM, YOU CAN LOSE MAIL!}
|
|
|
4299
|
|
|
4300 If your system uses the lock file protocol, and fascist restrictions
|
|
|
4301 prevent ordinary users from writing the lock files in
|
|
|
4302 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a
|
|
|
4303 suitable group such as @samp{mail}. You can use these commands (as
|
|
|
4304 root):
|
|
|
4305
|
|
|
4306 @example
|
|
|
4307 chgrp mail movemail
|
|
|
4308 chmod 2755 movemail
|
|
|
4309 @end example

4311 If your system uses the lock file protocol, and fascist restrictions
|
|
|
4312 prevent ordinary users from writing the lock files in
|
|
|
4313 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a
|
|
|
4314 suitable group such as @code{mail}. To do this, use the following
|
|
|
4315 commands (as root) after doing the make install.
|
|
|
4316
|
|
|
4317 @example
|
|
|
4318 chgrp mail movemail
|
|
|
4319 chmod 2755 movemail
|
|
|
4320 @end example
|
|
|
4321
|
|
|
4322 Installation normally copies movemail from the build directory to an
|
|
|
4323 installation directory which is usually under @file{/usr/local/lib}.
|
|
|
4324 The installed copy of @code{movemail} is usually in the directory
|
|
|
4325 @file{/usr/local/lib/emacs/VERSION/TARGET}. You must change the group
|
|
|
4326 and mode of the installed copy; changing the group and mode of the build
|
|
|
4327 directory copy is ineffective.

4505 TM stands for @dfn{Tools for MIME} and not Tiny MIME. TM integrates
|
|
|
4506 with all major XEmacs packages like Gnus (all flavors), VM, MH-E, and
|
|
|
4507 mailcrypt. It provides totally transparent and trouble-free MIME
|

4508 support. When appropriate a message will be decoded in place in an

4509 XEmacs buffer.
|
|

|
4713 @uref{http://sourceforge.net/projects/infodock/, InfoDock} is an
|
|
|
4714 integrated productivity toolset, mainly aimed at technical people,
|
|
|
4715 hosted at SourceForge.
|
|
428
|
4716
|
|
|
4717 InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
|
|
|
4718 the power of Emacs, but with an easier to use and more comprehensive
|
|
|
4719 menu-based user interface. The bottom portion of this text describes
|
|
|
4720 how it differs from XEmacs and GNU Emacs from the Free Software
|
|
|
4721 Foundation.
|
|
|
4722
|
|
|
4723 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
4724 environment. Although InfoDock is customizable, it is not intended for
|
|
|
4725 people who like basic versions of Emacs which need to be customized
|
|
|
4726 extensively for local use; standard Emacs distributions are better for
|
|
|
4727 such uses. InfoDock is for those people who want a complete,
|
|
|
4728 pre-customized environment in one package, which they need not touch
|
|
|
4729 more than once or twice a year to update to new revisions.
|
|
|
4730
|
|
|
4731 InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
|
|
|
4732 and Intel Linux systems. It is intended for use on a color display,
|
|
|
4733 although most features will work on monochrome monitors. Simply unpack
|
|
|
4734 InfoDock according to the instructions in the ID-INSTALL file and you
|
|
|
4735 are ready to run.
|
|
|
4736
|
|
|
4737 The InfoDock Manual is concise, yet sufficient as a user guide for users
|
|
|
4738 who have never used an Emacs-type editor before. For users who are
|
|
|
4739 already familiar with Emacs, it supplements the information in the GNU
|
|
|
4740 Emacs Manual.
|
|
|
4741
|
|
|
4742 InfoDock menus are much more extensive and more mature than standard
|
|
|
4743 Emacs menus. Each menu offers a @samp{Manual} item which displays
|
|
|
4744 documentation associated with the menu's functions.
|
|
|
4745
|
|
|
4746 @noindent
|
|
|
4747 Four types of menubars are provided:
|
|
|
4748 @enumerate
|
|
|
4749 @item
|
|
|
4750 An extensive menubar providing access to global InfoDock commands.
|
|
|
4751 @item
|
|
|
4752 Mode-specific menubars tailored to the current major mode.
|
|
|
4753 @item
|
|
|
4754 A simple menubar for basic editing to help novices get started with InfoDock.
|
|
|
4755 @item
|
|
|
4756 The standard XEmacs menubar.
|
|
|
4757 @end enumerate
|
|
|
4758
|
|
|
4759 Most modes also include mode-specific popup menus. Additionally, region and
|
|
|
4760 rectangle popup menus are included.
|
|
|
4761
|
|
|
4762 @samp{Hyperbole}, the everyday information manager, is a core part of
|
|
|
4763 InfoDock. This provides context-sensitive mouse keys, a rolodex-type
|
|
|
4764 contact manager, programmable hypertext buttons, and an autonumbered
|
|
|
4765 outliner with embedded hyperlink anchors.
|
|
|
4766
|
|
|
4767 The @samp{OO-Browser}, a multi-language object-oriented code browser, is a
|
|
|
4768 standard part of InfoDock.
|
|
|
4769
|
|
|
4770 InfoDock saves a more extensive set of user options than other Emacs
|
|
|
4771 versions.
|
|
|
4772
|
|
|
4773 InfoDock inserts a useful file header in many file types, showing the
|
|
|
4774 author, summary, and last modification time of each file. A summary
|
|
|
4775 program can then be used to summarize all of the files in a directory,
|
|
|
4776 for easy MANIFEST file creation.
|
|
|
4777
|
|
|
4778 Your working set of buffers is automatically saved and restored (if you
|
|
|
4779 answer yes to a prompt) between InfoDock sessions.
|
|
|
4780
|
|
|
4781 Refined color choices for code highlighting are provided for both dark and
|
|
|
4782 light background display frames.
|
|
|
4783
|
|
|
4784 The @kbd{C-z} key prefix performs frame-based commands which parallel the
|
|
|
4785 @kbd{C-x} key prefix for window-based commands.
|
|
|
4786
|
|
|
4787 The Smart Menu system is included for producing command menus on dumb
|
|
|
4788 terminals.
|
|
|
4789
|
|
|
4790 Lisp libraries are better categorized according to function.
|
|
|
4791
|
|
|
4792 Extensions and improvements to many areas of Emacs are included, such as:
|
|
|
4793 paragraph filling, mail reading with Rmail, shell handling, outlining, code
|
|
|
4794 highlighting and browsing, and man page browsing.
|

|
|
|
4871 AUC TeX is a package written by @email{abraham@@dina.kvl.dk, Per Abrahamsen}.
|
|
|
4872 Starting with XEmacs 19.16, AUC TeX is bundled with XEmacs. The
|
|
|
4873 following information is from the @file{README} and website.
|
|
|
4874
|
|
|
4875 AUC TeX is an extensible package that supports writing and formatting
|
|
|
4876 TeX files for most variants of GNU Emacs. Many different macro packages
|
|
|
4877 are supported, including AMS TeX, LaTeX, and TeXinfo.

4912 AUC TeX works fine on both stock Emacs and XEmacs has been doing so for

4913 a very very long time. This is mostly due to the work of

4936 @unnumberedsubsec Q4.7.5: Is there a reason for an Emacs package not to be included in XEmacs?
|
|
|
4937
|
|
|
4938 The reason for an Emacs package not to be included in XEmacs is
|
|
|
4939 usually one or more of the following:
|
|
|
4940
|
|
|
4941 @enumerate
|
|
|
4942 @item
|
|
|
4943 The package has not been ported to XEmacs. This will typically happen
|
|
|
4944 when it uses GNU-Emacs-specific features, which make it fail under
|
|
|
4945 XEmacs.
|
|
|
4946
|
|
|
4947 Porting a package to XEmacs can range from a trivial amount of change to
|
|
|
4948 a partial or full rewrite. Fortunately, the authors of modern packages
|
|
|
4949 usually choose to support both Emacsen themselves.
|
|
|
4950
|
|
|
4951 @item
|
|
|
4952 The package has been decided not to be appropriate for XEmacs. It may
|
|
|
4953 have an equivalent or better replacement within XEmacs, in which case
|
|
|
4954 the developers may choose not to burden themselves with supporting an
|
|
|
4955 additional package.
|
|
|
4956
|
|
|
4957 Each package bundled with XEmacs means more work for the maintainers,
|
|
|
4958 whether they want it or not. If you are ready to take over the
|
|
|
4959 maintenance responsibilities for the package you port, be sure to say
|
|
440
|
4960 so---we will more likely include it.
|
|
428
|
4961
|
|
|
4962 @item
|
|
|
4963 The package simply hasn't been noted by the XEmacs development. If
|
|
|
4964 that's the case, the messages like yours are very useful for attracting
|
|
|
4965 our attention.
|
|
|
4966
|
|
|
4967 @item
|
|
|
4968 The package was noted by the developers, but they simply haven't yet
|
|
|
4969 gotten around to including/porting it. Wait for the next release or,
|
|
|
4970 even better, offer your help. It will be gladly accepted and
|
|
|
4971 appreciated.

|

4983
|
|
|
4984 Yes. Of course XEmacs can use any network file system (such as NFS or
|
|
|
4985 Windows file sharing) you have available, and includes some
|
|
|
4986 optimizations and safety features appropriate to those environments.
|
|
|
4987
|
|
|
4988 It is also possible to transparently edit files via FTP, ssh, or rsh. That
|
|
|
4989 is, XEmacs makes a local copy using the transport in the background, and
|
|
|
4990 automatically refreshes the remote original from that copy when you save
|
|
|
4991 it. XEmacs also is capable of doing file system manipulations like
|
|
|
4992 creating and removing directories and files. The FTP interface is
|
|
|
4993 provided by the standard @samp{efs} package @ref{Top, EFS, , efs}. The
|
|
|
4994 ssh/rsh interface is provided by the optional @samp{tramp} package

5070
|

5071 For most modes, font-lock is already set up and just needs to be turned

|
|
428

5074 @lisp
|
|
462
|
5075 (require 'font-lock)

5076 @end lisp
|
|
|
5077
|
|
462
|
5078 to your @file{init.el}/@file{.emacs}. (You can turn it on for the
|
|
|
5079 current buffer and session only by @kbd{M-x font-lock-mode}.) See the
|
|
|
5080 file @file{etc/sample.init.el} (@file{etc/sample.emacs} in XEmacs
|
|
|
5081 versions prior to 21.4) for more information.

|
|
|
5092
|
|
|
5093 Well, first off, consider if you really want to do this. cc-mode is
|
|
|
5094 much more powerful than the old c-mode. If you're having trouble
|
|
|
5095 getting your old offsets to work, try using @code{c-set-offset} instead.
|
|
|
5096 You might also consider using the package @code{cc-compat}.
|
|
|
5097
|
|
462

5098 But, if you still insist, add the following lines to your @file{init.el}/@file{.emacs}:

5137 @unnumberedsubsec Q5.0.4: How can I enable auto-indent and/or Filladapt?
|
|
|
5138
|
|
|
5139 Put the following line in your @file{init.el}/@file{.emacs}:
|
|
428
|
5140
|
|
|
5141 @lisp
|
|
|
5142 (setq indent-line-function 'indent-relative-maybe)
|
|
|
5143 @end lisp
|
|
|
5144
|
|
|
5145 If you want to get fancy, try the @code{filladapt} package available
|
|
462
|
5146 standard with XEmacs. Put this into your @file{init.el}/@file{.emacs}:
|
|
428
|
5147
|
|
|
5148 @lisp
|
|
|
5149 (require 'filladapt)
|
|
462
|
5150 (setq-default filladapt-mode t)
|
|

5151 (add-hook 'c-mode-hook 'turn-off-filladapt-mode)
|
|
|
5152 @end lisp
|
|
|
5153
|
|
|
5154 This will enable Filladapt for all modes except C mode, where it doesn't
|
|
|
5155 work well. To turn Filladapt on only in particular major modes, remove
|
|
|
5156 the @code{(setq-default ...)} line and use
|
|
|
5157 @code{turn-on-filladapt-mode}, like this:
|
|
|
5158
|
|
|
5159 @lisp
|
|
|
5160 (add-hook 'text-mode-hook 'turn-on-filladapt-mode)
|
|
428
|
5161 @end lisp
|
|
|
5162
|
|
|
5163 You can customize filling and adaptive filling with Customize.
|

|
5164 Select from the @code{Options} menu
|
|
462
|
5165 @code{Advanced (Customize)->Emacs->Editing->Fill->Fill...}
|

428

5166 or type @kbd{M-x customize @key{RET} fill @key{RET}}.
|
|
|
5167
|
|
|
5168 Note that well-behaving text-lookalike modes will run
|
|
|
5169 @code{text-mode-hook} by default (e.g. that's what Message does). For
|
|
|
5170 the nasty ones, you'll have to provide the @code{add-hook}s yourself.

|

5176

462
|
5177 Try the following lisp in your @file{init.el}/@file{.emacs}:

|
5178

5179 @lisp

|
|

5182 @end lisp
|
|
|
5183
|
|
|
5184 @strong{WARNING}: note that changing the value of
|
|
|
5185 @code{default-major-mode} from @code{fundamental-mode} can break a large
|
|
|
5186 amount of built-in code that expects newly created buffers to be in
|
|
|
5187 @code{fundamental-mode}. (Changing from @code{fundamental-mode} to
|
|
|
5188 @code{text-mode} might not wreak too much havoc, but changing to
|
|
|
5189 something more exotic like a lisp-mode would break many Emacs packages).
|
|
|
5190
|
|
|
5191 Note that Emacs by default starts up in buffer @code{*scratch*} in
|
|
|
5192 @code{initial-major-mode}, which defaults to
|
|
|
5193 @code{lisp-interaction-mode}. Thus adding the following form to your
|
|
|
5194 Emacs init file will cause the initial @code{*scratch*} buffer to be put
|
|
|
5195 into auto-fill'ed @code{text-mode}:
|
|
|
5196
|
|
|
5197 @lisp
|
|
|
5198 (setq initial-major-mode
|
|
|
5199 (lambda ()
|
|
|
5200 (text-mode)
|
|
|
5201 (turn-on-auto-fill)))
|
|
|
5202 @end lisp
|
|
|
5203
|
|
|
5204 Note that after your init file is loaded, if
|
|
|
5205 @code{inhibit-startup-message} is @code{nil} (the default) and the
|
|
|
5206 startup buffer is @code{*scratch*} then the startup message will be
|
|
|
5207 inserted into @code{*scratch*}; it will be removed after a timeout by
|
|
|
5208 erasing the entire @code{*scratch*} buffer. Keep in mind this default
|
|
|
5209 usage of @code{*scratch*} if you desire any prior manipulation of
|
|
|
5210 @code{*scratch*} from within your Emacs init file. In particular,
|
|
|
5211 anything you insert into @code{*scratch*} from your init file will be
|
|
|
5212 later erased. Also, if you change the mode of the @code{*scratch*}
|
|
|
5213 buffer, be sure that this will not interfere with possible later
|
|
|
5214 insertion of the startup message (e.g. if you put @code{*scratch*} into
|
|
|
5215 a nonstandard mode that has automatic font lock rules, then the startup
|
|
|
5216 message might get fontified in a strange foreign manner, e.g. as code in
|
|
|
5217 some programming language).

5435 Emacs has a legacy of keyboards that produced characters with modifier
|
|
|
5436 bits, and therefore map a variety of input systems into this scheme even
|
|
|
5437 today. XEmacs is instead optimized for X events. This causes an
|
|
|
5438 incompatibility in the way key sequences are specified, but both Emacs
|
|
|
5439 and XEmacs will accept a key sequence as a vector of lists of modifiers
|
|
|
5440 that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
|
|
|
5441 @code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
|
|
|
5442 form for a single key, just (meta control a). Emacs has an abbreviated
|
|
|
5443 form for the Control and the Meta modifiers to string-characters (the
|
|
|
5444 ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
|
|
|
5445 that the abbreviated form works only for one-character key sequences,
|
|
|
5446 while Emacs users need to be aware that the string-character is rather
|
|
|
5447 limited. Specifically, the string-character can accommodate only 256
|
|
|
5448 different values, 128 of which have the Meta modifier and 128 of which
|
|
|
5449 have not. In each of these blocks, only 32 characters have the Control
|
|
|
5450 modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
|
|
|
5451 control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
|
|
|
5452 do not. Programmers are advised to use the full common form, both
|
|
|
5453 because it is more readable and less error-prone, and because it is
|
|
|
5454 supported by both Emacsen.

|
|

5456
|
|
|
5457 Another (even safer) way to be sure of the key-sequences is to use the
|
|
|
5458 @code{read-kbd-macro} function, which takes a string like @samp{C-c
|
|
|
5459 <up>}, and converts it to the internal key representation of the Emacs
|
|
|
5460 you use. The function is available both on XEmacs and GNU Emacs.

5521 A word in angle brackets, e.g., @code{<return>}, @code{<down>}, or

5522 @code{<f1>}, represents a function key. (Note that in the standard
|
|

5523 configuration, the function key @code{<return>} and the control key
|
|
|
5524 @key{RET} are synonymous.) You can use angle brackets on the words

5525 @key{RET}, @key{SPC}, etc., but they are not required there.

5534 (shift), @kbd{A-} (alt), @kbd{H-} (hyper), and @kbd{s-} (super) may
|
|
|
5535 precede a character or key notation. For function keys, the prefixes
|
|
|
5536 may go inside or outside of the brackets: @code{C-<down>} @equiv{}
|
|
|
5537 @code{<C-down>}. The prefixes may be written in any order: @kbd{M-C-x}
|

5538 @equiv{} @kbd{C-M-x}.
|

5539
|

5540 Prefixes are not allowed on multi-key words, e.g., @kbd{C-abc}, except
|

5541 that the Meta prefix is allowed on a sequence of digits and optional
|
|
|
5542 minus sign: @kbd{M--123} @equiv{} @kbd{M-- M-1 M-2 M-3}.

5566 you may need to add whitespace if the word would look like one of the

5567 above notations: @code{; ; ;} is a keyboard macro with three semicolons,
|
|

5568 but @code{;;;} is a comment. Likewise, @code{\ 1 2 3} is four keys but
|
|
|
5569 @code{\123} is a single key written in octal, and @code{< right >} is
|
|

5570 seven keys but @code{<right>} is a single function key. When in doubt,

5571 use whitespace.

5587 @itemize @bullet
|

5588 @item Global variables
|

5589
|
|

5590 You will typically @code{defvar} your global variable to a default
|
|
|
5591 value, and use @code{setq} to set it later.
|
|
|
5592
|
|
|
5593 It is never a good practice to @code{setq} user variables (like
|
|
|
5594 @code{case-fold-search}, etc.), as it ignores the user's choice
|
|
|
5595 unconditionally. Note that @code{defvar} doesn't change the value of a
|
|
|
5596 variable if it was bound previously. If you wish to change a
|
|
|
5597 user-variable temporarily, use @code{let}:
|
|
|
5598
|
|
|
5599 @lisp
|
|

5600 (let ((case-fold-search nil))

5608 @item Local variables
|
|
|
5609
|
|
|
5610 Bind them with @code{let}, which will unbind them (or restore their
|
|
|
5611 previous value, if they were bound) after exiting from the @code{let}
|
|
|
5612 form. Change the value of local variables with @code{setq} or whatever
|
|
|
5613 you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
|
|
|
5614 can even return one of its local variables.
|
|
|
5615
|
|
|
5616 Typical usage:
|
|
|
5617
|
|
|
5618 @lisp
|
|
|
5619 ;; iterate through the elements of the list returned by
|

|
|

5622 (while l
|

|
|
5624 (setq l (cdr l))))
|
|
|
5625 @end lisp
|
|
|
5626
|

5627 Another typical usage includes building a value simply to work with it.

5629 @lisp

|
|
|
5635 @end lisp
|
|

5636
|

5638 unbound (or regains old value) after exiting the form. The form also
|

5648 @unnumberedsubsec Q5.1.6: What is the typical misuse of @code{setq} ?
|
|
|
5649
|
|
|
5650 A typical misuse is probably @code{setq}ing a variable that was meant to
|
|
|
5651 be local. Such a variable will remain bound forever, never to be
|
|
|
5652 garbage-collected. For example, the code doing:
|
|
|
5653
|
|
|
5654 @lisp
|
|
|
5655 (defun my-function (whatever)
|
|
|
5656 (setq a nil)
|
|
|
5657 ... build a large list ...
|
|
|
5658 ... and exit ...)
|
|
|
5659 @end lisp
|
|
|
5660
|
|
|
5661 does a bad thing, as @code{a} will keep consuming memory, never to be
|
|
|
5662 unbound. The correct thing is to do it like this:
|
|
|
5663
|
|
|
5664 @lisp
|
|
|
5665 (defun my-function (whatever)
|
|
440
|
5666 (let (a) ; default initialization is to nil
|
|
428
|
5667 ... build a large list ...
|
|
|
5668 ... and exit, unbinding `a' in the process ...)
|
|
|
5669 @end lisp
|
|
|
5670
|
|
|
5671 Not only is this prettier syntactically, but it makes it possible for
|
|
|
5672 Emacs to garbage-collect the objects which @code{a} used to reference.
|
|
|
5673
|
|
|
5674 Note that even global variables should not be @code{setq}ed without
|
|
|
5675 @code{defvar}ing them first, because the byte-compiler issues warnings.
|
|
|
5676 The reason for the warning is the following:
|
|
|
5677
|
|
|
5678 @lisp
|
|
440
|
5679 (defun flurgoze nil) ; ok, global internal variable

5696 Many of the advanced features of this package, such as @code{defun*},
|
|
|
5697 @code{loop}, and @code{setf}, are implemented as Lisp macros. In
|
|
|
5698 byte-compiled code, these complex notations will be expanded into
|
|
|
5699 equivalent Lisp code which is simple and efficient. For example, the
|
|
|
5700 forms
|
|
|
5701
|
|
|
5702 @lisp
|
|
|
5703 (incf i n)
|

5704 (push x (car p))
|
|
|
5705 @end lisp
|
|
|
5706
|
|
|
5707 are expanded at compile-time to the Lisp forms
|
|
|
5708
|
|
|
5709 @lisp
|
|
|
5710 (setq i (+ i n))
|
|

|
|
|
5712 @end lisp
|
|
|
5713
|
|
|
5714 which are the most efficient ways of doing these respective operations
|
|
|
5715 in Lisp. Thus, there is no performance penalty for using the more
|
|
|
5716 readable @code{incf} and @code{push} forms in your compiled code.
|
|
|
5717
|
|
|
5718 @emph{Interpreted} code, on the other hand, must expand these macros
|
|
|
5719 every time they are executed. For this reason it is strongly
|
|
|
5720 recommended that code making heavy use of macros be compiled. (The
|
|
|
5721 features labelled @dfn{Special Form} instead of @dfn{Function} in this
|
|
|
5722 manual are macros.) A loop using @code{incf} a hundred times will
|
|
|
5723 execute considerably faster if compiled, and will also garbage-collect
|
|
|
5724 less because the macro expansion will not have to be generated, used,
|
|
|
5725 and thrown away a hundred times.
|
|
|
5726
|
|
|
5727 You can find out how a macro expands by using the @code{cl-prettyexpand}
|
|
|
5728 function.

|
|
|
5746 beginning of buffer:
|
|
|
5747
|
|
|
5748 @lisp
|
|
|
5749 (make-annotation (make-glyph '([FORMAT :file FILE]
|
|
|
5750 [string :data "fallback-text"]))
|
|
|
5751 (point-min)
|
|
|
5752 'text
|
|
|
5753 (current-buffer))
|
|
|
5754 @end lisp
|
|
|
5755
|
|
|
5756 Replace @samp{FORMAT} with an unquoted symbol representing the format of
|
|
|
5757 the image (e.g. @code{xpm}, @code{xbm}, @code{gif}, @code{jpeg}, etc.)
|
|
|
5758 Instead of @samp{FILE}, use the image file name
|
|
|
5759 (e.g.
|
|
|
5760 @iftex
|
|
|
5761 @*
|
|
|
5762 @end iftex
|
|
462
|
5763 @file{/usr/local/lib/xemacs-21.4/etc/recycle.xpm}).
|
|
428
|
5764
|
|
|
5765 You can turn this to a function (that optionally prompts you for a file
|
|
|
5766 name), and inserts the glyph at @code{(point)} instead of
|
|
|
5767 @code{(point-min)}.

5771

5772 I tried to use @code{map-extents} to do an operation on all the extents

5774 of extents. Is it buggy?
|
|

5775

|

5776 No. The documentation of @code{map-extents} states that it will iterate
|

5777 across the extents as long as @var{function} returns @code{nil}.
|
|
|
5778 Unexperienced programmers often forget to return @code{nil} explicitly,
|
|
|
5779 which results in buggy code. For instance, the following code is
|

5780 supposed to delete all the extents in a buffer, and issue as many

5872 @unnumberedsubsec Q5.3.1: How do you make XEmacs indent CL if-clauses correctly?
|
|
|
5873
|
|
|
5874 I'd like XEmacs to indent all the clauses of a Common Lisp @code{if} the
|
|
|
5875 same amount instead of indenting the 3rd clause differently from the
|
|
|
5876 first two.
|
|
|
5877
|
|
462
|
5878 One way is to add, to @file{init.el}/@file{.emacs}:
|
|
428
|
5879
|
|
|
5880 @lisp
|
|
|
5881 (put 'if 'lisp-indent-function nil)
|
|
|
5882 @end lisp
|
|
|
5883
|
|
|
5884 However, note that the package @code{cl-indent} that comes with
|
|
|
5885 XEmacs sets up this kind of indentation by default. @code{cl-indent}
|
|
|
5886 also knows about many other CL-specific forms. To use @code{cl-indent},
|
|
|
5887 one can do this:
|
|
|
5888
|
|
|
5889 @lisp
|
|
|
5890 (load "cl-indent")
|
|
|
5891 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
|
5892 @end lisp
|
|
|
5893
|
|
|
5894 One can also customize @file{cl-indent.el} so it mimics the default
|
|
|
5895 @code{if} indentation @code{then} indented more than the @code{else}.
|
|
|
5896 Here's how:
|
|
|
5897
|
|
|
5898 @lisp
|
|
|
5899 (put 'if 'common-lisp-indent-function '(nil nil &body))
|
|
|
5900 @end lisp
|
|
|
5901
|
|
|
5902 Also, a new version (1.2) of @file{cl-indent.el} was posted to
|
|
|
5903 comp.emacs.xemacs on 12/9/94. This version includes more documentation
|
|
|
5904 than previous versions. This may prove useful if you need to customize
|
|

5905 any indent-functions.

|
|
|
5944
|
|
|
5945 You can specify what paths to use by using a number of different flags
|
|
|
5946 when running configure. See the section MAKE VARIABLES in the top-level
|
|
|
5947 file INSTALL in the XEmacs distribution for a listing of those flags.
|
|
|
5948
|
|
|
5949 Most of the time, however, the simplest fix is: @strong{do not} specify
|
|
|
5950 paths as you might for GNU Emacs. XEmacs can generally determine the
|
|
|
5951 necessary paths dynamically at run time. The only path that generally
|
|
|
5952 needs to be specified is the root directory to install into. That can
|
|
|
5953 be specified by passing the @code{--prefix} flag to configure. For a
|
|
|
5954 description of the XEmacs install tree, please consult the @file{NEWS}

6039 Yes, abbrevs only expands word-syntax strings. While XEmacs does not

|
|
|
6055
|
|
|
6056 Firstly there is an ftp site which describes X-faces and has the
|
|
|
6057 associated tools mentioned below, at
|
|
|
6058 @uref{ftp://ftp.cs.indiana.edu:/pub/faces/}.
|
|
|
6059
|
|

6067 Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
|
|

6068 and then compile the face.
|
|
|
6069
|
|
|
6070 @item
|
|
|
6071 @example
|
|
|
6072 cat file.xbm | xbm2ikon |compface > file.face
|
|
|
6073 @end example
|
|
|
6074
|
|
|
6075 @item
|
|
|
6076 Then be sure to quote things that are necessary for emacs strings:
|
|
|
6077
|
|
|
6078 @example
|
|
|
6079 cat ./file.face | sed 's/\\/\\\\/g'
|
|
|
6080 @iftex
|
|
|
6081 \ @*
|
|
|
6082 @end iftex
|
|
|
6083 | sed 's/\"/\\\"/g' > ./file.face.quoted
|
|
|
6084 @end example
|
|
|
6085
|
|
|
6086 @item
|
|
|
6087 Then set up emacs to include the file as a mail header - there were a
|
|
|
6088 couple of suggestions here---either something like:
|
|
|
6089
|
|
|
6090 @lisp
|
|
|
6091 (setq mail-default-headers
|
|
|
6092 "X-Face: @email{Ugly looking text string here}")
|
|
|
6093 @end lisp
|
|
|
6094
|
|
|
6095 Or, alternatively, as:
|
|
|
6096
|
|
|
6097 @lisp
|
|
|
6098 (defun mail-insert-x-face ()
|
|
|
6099 (save-excursion
|
|
|
6100 (goto-char (point-min))
|
|
|
6101 (search-forward mail-header-separator)
|
|
|
6102 (beginning-of-line)
|
|
|
6103 (insert "X-Face:")
|
|
|
6104 (insert-file-contents "~/.face")))
|
|
|
6105
|
|
|
6106 (add-hook 'mail-setup-hook 'mail-insert-x-face)
|
|
|
6107 @end lisp
|
|
|
6108 @end enumerate
|
|
|
6109
|
|
|
6110 However, 2 things might be wrong:
|
|
|
6111
|
|
|
6112 Some versions of pbmtoicon produces some header lines that is not
|
|
|
6113 expected by the version of compface that I grabbed. So I found I had to
|
|
|
6114 include a @code{tail +3} in the pipeline like this:
|
|
|
6115
|
|
|
6116 @example
|
|
|
6117 cat file.xbm | xbm2ikon | tail +3 |compface > file.face
|
|
|
6118 @end example
|
|
|
6119
|
|
|
6120 Some people have also found that if one uses the @code{(insert-file)}
|
|
|
6121 method, one should NOT quote the face string using the sed script .
|
|
|
6122
|
|
|
6123 It might also be helpful to use @email{stig@@hackvan.com, Stig's} script
|
|
|
6124 (included in the compface distribution at XEmacs.org) to do the
|
|
430
|
6125 conversion.
|
|
|

6165 @code{Info-directory-list} @emph{if} it is available at startup, but not
|
|
|
6166 all Emacsen define it.
|

6167

6168 @item

6169 Emacs Info looks for a standard @file{dir} file in each of the

6170 directories scanned from #1 and magically concatenates them together.
|
|
|
6171
|
|

6172 @item
|
|
|
6173 XEmacs Info looks for a @file{localdir} file (which consists of just the
|
|
|
6174 menu entries from a @file{dir} file) in each of the directories scanned
|
|
|
6175 from #1 (except the first), does a simple concatenation of them, and
|
|
|
6176 magically attaches the resulting list to the end of the menu in the

6185 @unnumberedsubsec Q5.3.12: What do I need to change to make printing work?
|
|
|
6186
|
|
|
6187 For regular printing there are two variables that can be customized.
|
|
|
6188
|
|
|
6189 @table @code
|
|
|
6190 @item lpr-command
|
|
|
6191 This should be set to a command that takes standard input and sends
|
|
|
6192 it to a printer. Something like:
|
|
|
6193
|
|
|
6194 @lisp
|
|
|
6195 (setq lpr-command "lp")
|
|
|
6196 @end lisp
|
|
|
6197
|
|
|
6198 @item lpr-switches
|
|
|
6199 This should be set to a list that contains whatever the print command
|
|
|
6200 requires to do its job. Something like:
|
|
|
6201
|
|
|
6202 @lisp
|
|
|
6203 (setq lpr-switches '("-depson"))
|
|
|
6204 @end lisp
|
|
|
6205 @end table
|
|
|
6206
|
|
|
6207 For postscript printing there are three analogous variables to
|
|
|
6208 customize.
|
|
|
6209
|
|
|
6210 @table @code
|
|
|
6211 @item ps-lpr-command
|
|
|
6212 This should be set to a command that takes postscript on standard input
|
|
|
6213 and directs it to a postscript printer.
|
|
|
6214
|
|
|
6215 @item ps-lpr-switches
|
|
|
6216 This should be set to a list of switches required for
|
|
|
6217 @code{ps-lpr-command} to do its job.
|
|
|
6218
|
|
|
6219 @item ps-print-color-p
|
|
|
6220 This boolean variable should be set @code{t} if printing will be done in
|
|
|
6221 color, otherwise it should be set to @code{nil}.
|
|
|
6222 @end table
|
|
|
6223
|
|
|
6224 NOTE: It is an undocumented limitation in XEmacs that postscript
|
|
|
6225 printing (the @code{Pretty Print Buffer} menu item) @strong{requires} a
|
|
|
6226 window system environment. It cannot be used outside of X11.

6231 @unnumberedsubsec Q5.4.1: What are bignums, ratios, and bigfloats in Lisp?
|
|
|
6232
|
|
|
6233 Thanks to @email{james@@xemacs.org, Jerry James}, XEmacs 21.5.18 and
|
|
|
6234 later can use the capabilities of multiple-precision libraries that may
|
|
|
6235 be available for your platform. The GNU Multiple Precision (GMP) and
|
|
|
6236 BSD Multiple Precision (MP) libraries are partially supported. GMP
|
|
|
6237 gives you @dfn{bignums} (arbitrary precision integers), @dfn{ratios}
|
|
|
6238 (arbitrary precision fractions), and @dfn{bigfloats} (arbitrary
|
|
|
6239 precision floating point numbers). GNU MP is better-supported by XEmacs
|
|
|
6240 at the time of writing (2004-04-06). BSD MP support does not include
|
|
|
6241 ratios or bigfloats, and it throws errors that aren't understood.
|
|
|
6242
|
|
|
6243 In most cases, bignum support should be transparent to users and Lisp
|
|
|
6244 programmers. A bignum-enabled XEmacs will automatically convert from
|
|
|
6245 fixnums to bignums and back in pure integer arithmetic, and for GNU MP,
|
|
|
6246 from floats to bigfloats. (Bigfloats must be explicitly coerced to
|
|
|
6247 other types, even if they are exactly representable by less precise
|
|
|
6248 types.) The Lisp reader and printer have been enhanced to handle
|
|
|
6249 bignums, as have the mathematical functions. Rationals (fixnums,
|
|
|
6250 bignums, and ratios) are printed using the @samp{%d}, @samp{%o},
|
|
|
6251 @samp{%x}, and @samp{%u} format conversions. The read syntax for ratios
|
|
|
6252 is @samp{3/5}.
|
|
|
6253
|
|
|
6254 User-visible changes in behavior include (in probable order of annoyance)
|
|
|
6255

6258 Arithmetic can cause a segfault, depending on your MP library

|
|
|
6260
|
|
|
6261 @item
|
|
|
6262 Terminology is not Common-Lisp-conforming. For example, ``integer'' for
|
|
|
6263 Emacs Lisp means what Common Lisp calls ``fixnum''. This issue is being
|
|
|
6264 investigated, but the use of ``integer'' for fixnum is pervasive and may
|
|
|
6265 cause backward-compatibility and GNU-Emacs-compatibility problems.
|
|
|
6266
|
|
|
6267 @item
|
|
|
6268 Many operations that used to cause a range error now succeed, with
|
|
|
6269 intermediate results and return values coerced to bignums as needed.
|
|
|
6270
|
|
|
6271 @item
|
|

6272 An atom with ratio read syntax now returns a number, not a symbol.
|
|
|
6273
|
|
|
6274 @item
|
|
|
6275 The @samp{%u} format conversion will now give an error if its argument
|
|
|
6276 is negative. (Without MP, it prints a number which Lisp can't read.)
|
|
|
6277 @end itemize
|
|
|
6278
|
|
|
6279 @emph{Surgeon General's Warning}: The automatic conversions cannot be
|
|
|
6280 disabled at runtime. New functions have been added which produce
|
|
|
6281 ratios, so there should be few surprises with type conflicts, but they
|
|
|
6282 can't be ruled out. ``Arbitrary'' precision means precisely what it
|
|
|
6283 says. If you work with extremely large numbers, your machine may
|
|
|
6284 arbitrarily decide to hand you an unpleasant surprise rather than a
|
|
|
6285 bignum @ref{Q5.4.2}.
|
|
|
6286
|
|
|
6287 To configure with GNU MP, add
|
|
|
6288 @samp{--use-number-lib=gmp}
|
|
|
6289 to your invocation of @file{configure}. For BSD MP, use
|
|
|
6290 @samp{--use-number-lib=mp}.
|
|
|
6291
|
|
|
6292 If you would like to help with bignum support, especially on BSD MP,
|
|
|
6293 please subscribe to the @uref{http://www.xemacs.org/Lists/#xemacs-beta,

|
6297 than to writing new code, feel free to fill in the gap!

6303 GMP by default allocates temporaries on the stack. If you run out of
|
|
|
6304 stack space, you're dead; there is no way that we know of to reliably
|
|
|
6305 detect this condition, because @samp{alloca} is typically implemented to
|
|
|
6306 be @emph{fast} rather than robust. If you just need a little more
|
|
|
6307 oomph, use a bigger stack (@emph{e.g.}, the @file{ulimit -s} command in
|
|
|
6308 bash(1)). If you want robustness at the cost of speed, configure GMP

6309 with @samp{--disable-alloca} and rebuild the GMP library.

6332 Meditate on the deeper truths of @samp{eql}, in which numbers of the same

6333 type which have equal values compare equal, and @samp{=}, which does any
|
|
|
6334 necessary type coercions before comparing for equality.
|
|
|
6335
|
|
|
6336 Yeah, yeah, it has always worked for integer types, because fixnums and
|
|
|
6337 characters have an immediate representation. Sorry about that;
|
|
|
6338 arbitrary precision obviously requires consing new objects because the
|
|
|
6339 objects are ``large'' and of variable size, and the definition of
|
|
|
6340 @samp{eq} does not permit different objects to compare as equal.

6395 Beginning with release 21.0, XEmacs has worked under MS Windows. A

|
|
6396 group of dedicated developers actively maintains and improves the
|
|
|
6397 Windows-specific portions of the code. The mailing list at
|

|
6398 @email{xemacs-nt@@xemacs.org} is dedicated to that effort (please use

|
|
|
6400 works on all versions of Windows.)
|
|
|
6401
|
|
|
6402 As of May 2001, XEmacs on MS Windows is stable and full-featured, and
|
|
|
6403 has been so for a year or more -- in fact, some features, such as
|
|
|
6404 printing, actually work better on Windows than native Unix. However,
|
|
|
6405 the internationalization (Mule) support does not work -- although this
|
|
|
6406 is being actively worked on.

|

6443
|

6444 It depends on the knowledge and time you possess. If you are a
|
|
|
6445 programmer, try to build XEmacs and see if you can improve it.
|
|
|
6446 Windows-specific improvements like integration with established
|
|
|
6447 Windows environments are especially sought after.
|
|
|
6448
|

6449 Otherwise, you can still help by downloading the binaries, using

6450 XEmacs as your everyday editor and reporting bugs you find to the

|
|

6458 @unnumberedsubsec Q6.0.6: What are Cygwin and MinGW, and do I need them to run XEmacs?
|
|
|
6459
|
|
|
6460 To answer the second part of the question: No, you, you don't need
|
|
|
6461 Cygwin or MinGW to build or to run XEmacs. But if you have them and
|
|
|
6462 want to use them, XEmacs supports these environments.
|
|
|
6463
|
|
|
6464 (One important reason to support Cygwin is that it lets the MS Windows
|
|
|
6465 developers test out their code in a Unix environment without actually
|
|
|
6466 having to have a Unix machine around. For this reason alone, Cygwin
|
|
|
6467 support is likely to remain supported for a long time in XEmacs. Same
|
|
|
6468 goes for the X support under Cygwin, for the same reasons. MinGW
|
|
|
6469 support, on the other hand, depends on volunteers to keep it up to date;
|
|
|
6470 but this is generally not hard.)
|
|
|
6471
|
|
|
6472 Cygwin is a set of tools providing Unix-like API on top of Win32.
|
|
|
6473 It makes it easy to port large Unix programs without significant
|
|
|
6474 changes to their source code. It is a development environment as well
|
|
|
6475 as a runtime environment.
|
|
|
6476
|
|
|
6477 When built with Cygwin, XEmacs supports all display types -- TTY, X &
|
|
|
6478 Win32 GUI, and can be built with support for all three simultaneously.
|
|
|
6479 If you build with Win32 GUI support then the Cygwin version uses the
|
|
|
6480 majority of the Windows-specific code, which is mostly related to
|
|
|
6481 display. If you want to build with X support you need X libraries (and
|
|
|
6482 an X server to display XEmacs on); see @ref{Q6.1.4}. TTY and Win32 GUI
|
|
|
6483 require no additional libraries beyond what comes standard with Cygwin.
|
|
|
6484
|
|
|
6485 The advantages of the Cygwin version are that it integrates well with
|
|
|
6486 the Cygwin environment for existing Cygwin users; uses configure so
|
|
|
6487 building with different features is very easy; and actively supports X &
|
|
|
6488 TTY. Furthermore, the entire Cygwin environment and compiler are free,
|
|
|
6489 whereas Visual C++ costs money.
|
|
|
6490
|
|
|
6491 The disadvantage is that it requires the whole Cygwin environment,
|
|
|
6492 whereas the native port requires only a suitable MS Windows compiler.
|
|
|
6493 Also, it follows the Unix filesystem and process model very closely
|
|
|
6494 (some will undoubtedly view this as an advantage).
|
|
|
6495
|
|
|
6496 See @uref{http://sources.redhat.com/cygwin/} for more information on
|
|
|
6497 Cygwin.
|
|
|
6498
|
|
|
6499 MinGW is a collection of header files and import libraries that allow
|
|
|
6500 one to use GCC under the Cygwin environment to compile and produce
|
|
|
6501 exactly the same native Win32 programs that you can using Visual C++.
|
|
|
6502 Programs compiled with MinGW make use of the standard Microsoft runtime
|
|
|
6503 library @file{MSVCRT.DLL}, present on all Windows systems, and look,
|
|
|
6504 feel, and act like a standard Visual-C-produced application. (The only
|
|
|
6505 difference is the compiler.) This means that, unlike a
|
|
|
6506 standardly-compiled Cygwin application, no extra runtime support
|
|
|
6507 (e.g. Cygwin's @file{cygwin1.dll}) is required. This, along with the
|
|
|
6508 fact that GCC is free (and works in a nice Unix-y way in a nice Unix-y
|
|
|
6509 environment, for those die-hard Unix hackers out there), is the main
|
|
|
6510 advantage of MinGW. It is also potentially faster than Cygwin because
|
|
|
6511 it has less overhead when calling Windows, but you lose the POSIX
|
|
|
6512 emulation layer, which makes Unix programs harder to port. (But this is
|
|
|
6513 irrelevant for XEmacs since it's already ported to Win32.)
|
|
|
6514

|

6518 @unnumberedsubsec Q6.0.7: What exactly are all the different ways to build XEmacs under Windows?
|
|
|
6519
|
|
|
6520 XEmacs can be built in several ways in the MS Windows environment.
|
|
462
|
6521
|
|
|
6522 The standard way is what we call the "native" port. It uses the Win32
|
|
|
6523 API and has no connection with X whatsoever -- it does not require X
|
|
|
6524 libraries to build, nor does it require an X server to run. The native
|
|
|
6525 port is the most reliable version and provides the best graphical
|
|
|
6526 support. Almost all development is geared towards this version, and
|
|
|
6527 there is little reason not to use it.
|
|
|
6528
|
|
593
|
6529 The second way to build is the Cygwin port. It takes advantage of
|
|
|
6530 Cygnus emulation library under Win32. @xref{Q6.0.6}, for more
|
|
|
6531 information.
|
|
|
6532
|
|
|
6533 A third way is the MinGW port. It uses the Cygwin environment to build
|
|
|
6534 but does not require it at runtime. @xref{Q6.0.6}, for more
|
|
|
6535 information.
|
|
|
6536
|
|
|
6537 Finally, you might also be able to build the non-Cygwin, non-MinGW "X"
|
|
|
6538 port. This was actually the first version of XEmacs that ran under MS
|
|
|
6539 Windows, and although the code is still in XEmacs, it's essentially
|
|
|
6540 orphaned and it's unlikely it will compile without a lot of work. If
|
|
|
6541 you want an MS Windows versin of XEmacs that supports X, use the Cygwin
|
|
|
6542 version. (The X support there is actively maintained, so that Windows
|
|
|
6543 developers can test the X support in XEmacs.)

|
|
|
6663
|
|
|
6664 As of May 2001, we are recommending that you use the port of XFree86 to
|
|
|
6665 Cygwin. This has recently stabilized, and will undoubtedly soon make
|
|
|
6666 most other MS Windows X servers obsolete. It is what the Windows
|
|
|
6667 developers use to test the MS Windows X support.
|
|
|
6668
|
|
|
6669 To install, go to @uref{http://xfree86.cygwin.com/}. There is a
|
|
|
6670 detailed description on that site of exactly how to install it. This
|
|
|
6671 installation also provides the libraries, include files, and other stuff
|
|
|
6672 needed for development; a large collection of internationalized fonts;
|
|
|
6673 the standard X utilities (xterm, twm, etc.) -- in a word, the works.
|
|
|
6674
|
|
|
6675 NOTE: As of late May 2001, there is a bug in the file
|
|
|
6676 @file{startxwin.bat}, used to start X Windows. It passes the option
|
|
|
6677 @samp{-engine -4} to the X server, which is bogus -- you need to edit
|
|
|
6678 the file and change it to @samp{-engine 4}.

6683
|
|
|
6684 To compile under Cygwin, all you need to do is install XFree86
|
|
|
6685 (@pxref{Q6.1.6}). Once installed, @file{configure} should automatically
|
|
|
6686 find the X libraries and compile with X support.
|
|
|
6687
|
|
|
6688 As noted above, the non-Cygwin X support is basically orphaned, and
|
|
|
6689 probably won't work. But if it want to try, it's described in
|
|
|
6690 @file{nt/README} in some detail. Basically, you need to get X11
|
|
|
6691 libraries from ftp.x.org, and compile them. If the precompiled versions
|
|
|
6692 are available somewhere, we don't know of it.

|
|
|
6698
|
|
611
|
6699 The XEmacs (and Emacs in general) user interface is pretty different
|
|
|
6700 from what is expected of a typical MS Windows program. How does the MS
|
|
|
6701 Windows port cope with it?
|
|
593
|
6702
|
|
|
6703 As a general rule, we follow native MS Windows conventions as much as
|
|
611
|
6704 possible. 21.4 is a fairly complete Windows application, supporting
|
|
|
6705 native printing, system file dialog boxes, tool tips, etc. In cases
|
|
|
6706 where there's a clear UI conflict, we currently use normal Unix XEmacs
|
|
|
6707 behavior by default, but make sure the MS Windows "look and feel" (mark
|
|
|
6708 via shift-arrow, self-inserting deletes region, Alt selects menu items,
|
|
|
6709 etc.) is easily configurable (respectively: using the variable
|
|
|
6710 @code{shifted-motion-keys-select-region} in 21.4 and above [it's in fact
|
|
|
6711 the default in these versions], or the @file{pc-select} package; using
|
|
|
6712 the @file{pending-del} package; and setting the variable
|
|
|
6713 @code{menu-accelerator-enabled} to @code{menu-force} in 21.4 and above).
|
|
|
6714 In fact, if you use the sample @file{init.el} file as your init file,
|
|
|
6715 you will get all these behaviors automatically turned on.
|
|
593
|
6716
|
|
|
6717 In future versions, some of these features might be turned on by

|
|
|
6817
|
|
|
6818 In his flavor of Emacs 20, Richard Stallman has renamed all the @samp{win32-*}
|
|
|
6819 symbols to @samp{w32-*}. Does XEmacs do the same?
|
|
|
6820
|
|
|
6821 We consider such a move counter-productive, thus we do not use the
|
|
|
6822 @samp{w32} prefix. (His rather questionable justification was that he
|
|
|
6823 did not consider Windows to be a "winning" platform.) However, the name
|
|
|
6824 @samp{Win32} is not particularly descriptive outside the Windows world,
|
|
|
6825 and using just @samp{windows-} would be too generic. So we chose a
|
|
|
6826 compromise, the prefix @samp{mswindows-} for Windows-related variables
|
|
|
6827 and functions.
|
|
|
6828
|
|
|
6829 Thus all the XEmacs variables and functions directly related to either
|
|
|
6830 the Windows GUI or OS are prefixed @samp{mswindows-} (except for a
|
|
|
6831 couple of debugging variables, prefixed @samp{debug-mswindows-}). From
|
|
|
6832 an architectural perspective, however, we believe that this is mostly a
|
|
|
6833 non-issue because there should be a very small number of
|
|
|
6834 window-systems-specific variables anyway. Whenever possible, we try to
|
|
|
6835 provide generic interfaces that apply to all window systems.

|
|
|
6944
|
|
|
6945 Yes.
|
|
|
6946
|
|
|
6947 The console was there because @file{temacs} (and in turn, @file{xemacs})
|
|
|
6948 was a console application, and Windows typically creates a new
|
|
|
6949 console for a console process unless the creating process requests that
|
|
|
6950 one isn't created. This used to be fixed with @file{runemacs}, a small
|
|
|
6951 Windows application that existed merely to start @file{xemacs}, stating
|
|
|
6952 that it didn't want a console.
|

|
|
6955 application. The explanation of what that means is included for
|
|
|
6956 educational value.
|
|
|
6957
|
|
|
6958 When building an application to be run in a Win32 environment, you must
|
|
|
6959 state which sub-system it is to run in. Valid subsystems include
|
|
|
6960 "console" and "gui". The subsystem you use affects the run time
|
|
|
6961 libraries linked into your application, the start up function that is
|
|
|
6962 run before control is handed over to your application, the entry point
|
|
|
6963 to your program, and how Windows normally invokes your program. (Console
|
|
|
6964 programs automatically get a console created for them at startup if
|
|
|
6965 their stdin/stdout don't point anywhere useful, which is the case when
|
|
|
6966 run from the GUI. This is a stupid design, of course -- instead, the
|
|
|
6967 console should get created only when the first I/O actually occurs!
|
|
|
6968 GUI programs have an equally stupid design: When called from
|
|
|
6969 @file{CMD.EXE}/@file{COMMAND.COM}, their stdin/stdout will be set to
|
|
|
6970 point nowhere useful, even though the command shell has its own
|
|
|
6971 stdin/stdout. It's as if someone who had learned a bit about stdio but
|
|
|
6972 had no actual knowledge of interprocess communication designed the
|
|
|
6973 scheme; unfortunately, the whole process-communication aspect of the
|
|
|
6974 Win32 API is equally badly designed.) For example, the entry point for a
|
|
|
6975 console app is "main" (which is what you'd expect for a C/C++ program),
|
|
|
6976 but the entry point for a "gui" app is "WinMain". This confuses and
|
|
|
6977 annoys a lot of programmers who've grown up on Unix systems, where the
|
|
|
6978 kernel doesn't really care whether your application is a gui program or
|
|
|
6979 not.
|
|
|
6980
|
|
|
6981 For reasons not altogether clear, and are lost in the mists of time and
|
|
|
6982 tradition, XEmacs on Win32 started out as a console application, and
|
|
|
6983 therefore a console was automatically created for it. (It may have been
|
|
|
6984 made a console application partly because a console is needed in some
|
|
|
6985 circumstances, especially under Win95, to interrupt, terminate, or send
|
|
|
6986 signals to a child process, and because of the bogosity mentioned above
|
|
|
6987 with GUI programs and the standard command shell. Currently, XEmacs
|
|
|
6988 just creates and immediately hides a console when necessary, and
|
|
|
6989 works around the "no useful stdio" problem by creating its own console
|
|
|
6990 window as necessary to display messages in.)

7008 @unnumberedsubsec Q6.4.1 XEmacs won't start on Windows.
|
|
442
|
7009
|
|
|
7010 XEmacs relies on a process called "dumping" to generate a working
|
|
|
7011 executable. Under MS-Windows this process effectively fixes the memory
|
|
|
7012 addresses of information in the executable. When XEmacs starts up it tries
|
|
|
7013 to reserve these memory addresses so that the dumping process can be
|
|
593
|
7014 reversed -- putting the information back at the correct addresses.
|
|
|
7015 Unfortunately some .DLLs (for instance the soundblaster driver) occupy
|
|
442
|
7016 memory addresses that can conflict with those needed by the dumped XEmacs
|
|
|
7017 executable. In this instance XEmacs will fail to start without any
|
|
|
7018 explanation. Note that this is extremely machine specific.
|
|
|
7019
|
|
|
7020 21.1.10 includes a fix for this that makes more intelligent guesses
|
|
|
7021 about which memory addresses will be free, and this should cure the
|
|
593
|
7022 problem for most people. 21.4 implements "portable dumping", which
|
|
|
7023 eliminates the problem altogether. We recommend you use the 21.4
|
|
|
7024 binaries, but you can use the 21.1 binaries if you are very paranoid
|
|
|

|

7089
|
|
|
7090 21.4 was the "stable" version of the 21.2 series, which was considered
|
|
|
7091 "experimental" throughout its life; thus there were no "official"
|
|
|
7092 releases at all. In essence, XEmacs is now following the "alternating"
|
|
|
7093 scheme of Linux, where at any point there are at least two different
|
|
|
7094 development branches, one "stable" and one "experimental". Periodic
|
|
|
7095 releases happen in both branches, but those in the experimental branch
|
|
|
7096 are not tested as well, and there's no guarantee they will work at all.
|
|
|
7097 The experiemental branch is open to any and all code that's acceptable
|
|
|
7098 to the developers; the stable branch, however, is in general limited
|
|
|
7099 only to bug fixes, and all contributions are carefully reviewed to make
|
|
|
7100 sure they will increase and not decrease stability.
|
|
|
7101
|
|
|
7102 21.3 never existed at all; it was decided to follow the Linux scheme
|
|
|
7103 exactly, where odd-numbered series are experimental and even-numbered
|
|
|
7104 ones stable.

7345
|

7346 XEmacs 20.4 is a bugfix release with no user-visible changes.

|
|

7351
|
|
|
7352 XEmacs 20.3 was released in November 1997. It contains many bugfixes,
|
|
|
7353 and a number of new features, including Autoconf 2 based configuration,
|
|
|
7354 additional support for Mule (Multi-language extensions to Emacs), many
|
|
|
7355 more customizations, multiple frames on TTY-s, support for multiple info
|
|
|
7356 directories, an enhanced gnuclient, improvements to regexp matching,
|
|
|
7357 increased MIME support, and many, many synches with GNU Emacs 20.
|
|
|
7358
|
|
|
7359 The XEmacs/Mule support has been only seriously tested in a Japanese
|
|
|
7360 locale, and no doubt many problems still remain. The support for
|
|
|
7361 ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
|
|
440
|
7362 price---about a 30% slowdown from 19.16. We're making progress on
|
|
428
|
7363 improving performance and XEmacs 20.3 compiled without Mule (which is
|
|
|
7364 the default) is definitely faster than XEmacs 19.16.
|
|
|
7365
|
|
|
7366 XEmacs 20.3 is the first non-beta v20 release, and will be the
|
|
|
7367 basis for all further development.

7370 @unnumberedsubsec Q7.0.6: What's new in XEmacs 20.2?
|
|
|
7371
|
|
|
7372 The biggest changes in 20.2 include integration of EFS (the next
|
|
|
7373 generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
|
|
|
7374 major mode for editing Tex and LaTeX, and a lot of other stuff). Many
|
|
|
7375 bugs from 20.0 have been fixed for this release. 20.2 also contains a
|
|
|
7376 new system for customizing XEmacs options, invoked via @kbd{M-x
|
|
|
7377 customize}.
|
|
|
7378
|
|
|
7379 XEmacs 20.2 is the development release (20.0 was beta), and is no longer
|
|
|
7380 considered unstable.

7421 @end lisp
|
|

7422
|

7423 returns the empty string. This is because something somewhere
|
|
|
7424 replaces the XPM data with a glyph --- I haven't figured out where
|
|
|
7425 this occurs.
