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

401 complain about repeatedly having to answer questions.
|
|
|
402 @email{ben@@xemacs.org, Ben Wing} and @email{cthomp@@xemacs.org, Chuck
|
|
|
403 Thompson}, the principal authors of XEmacs, then took over and Ben did
|
|
|
404 a massive update reorganizing the whole thing. At which point Anthony
|
|
|
405 took back over, but then had to give it up again. Some of the other

471 An alternative to GNU Emacs, originally based on an early alpha version
|
|
|
472 of FSF's version 19, and has diverged quite a bit since then. XEmacs
|
|
|
473 was known as Lucid Emacs through version 19.10. Almost all features of
|
|
|
474 GNU Emacs are supported in XEmacs. The maintainers of XEmacs actively
|
|
|
475 track changes to GNU Emacs while also working to add new features.

570 There are currently irreconcilable differences in the views about
|
|
|
571 technical, programming, design and organizational matters between RMS
|
|
|
572 and the XEmacs development team which provide little hope for a merge to
|
|
|
573 take place in the short-term future.
|
|
|
574
|
|
|
575 If you have a comment to add regarding the merge, it is a good idea to
|
|
|
576 avoid posting to the newsgroups, because of the very heated flamewars
|

577 that often result. Mail your questions to @email{xemacs-beta@@xemacs.org} and

583 Probably the easiest way, if everything is installed, is to use info, by

|
|
584 pressing @kbd{C-h i}, or selecting @code{Manuals->Info} from the Help Menu.
|

585

586 Also, @kbd{M-x apropos} will look for commands for you.

|

633 Thanks to efforts of many people, coordinated by
|
|
|
634 @email{davidh@@wr.com.au, David Hobley} and @email{marcpa@@cam.org, Marc
|
|
|
635 Paquette}, beta versions of XEmacs now run on 32-bit Windows platforms
|
|
|
636 (NT and 95). The current betas require having an X server to run
|
|
|
637 XEmacs; however, a native NT/95 port is in alpha, thanks to
|
|
|
638 @email{jhar@@tardis.ed.ac.uk, Jonathan Harris}.
|
|
|
639
|
|
|
640 Although some features are still unimplemented, XEmacs 21.0 will support
|
|
|
641 MS-Windows.
|
|
|
642
|
|
|
643 The NT development is now coordinated by a mailing list at

|
|
896 @unnumberedsubsec Q1.3.1: What is the status of XEmacs v20?
|
|
|
897
|
|
|
898 XEmacs v20 is the version of XEmacs that includes MULE (Asian-language)
|
|
|
899 support. XEmacs 20.0 was released in February 1997, followed by XEmacs
|
|
|
900 20.2 in May, XEmacs 20.3 in November and XEmacs 20.4 in February 1998. When compiled without MULE
|
|
|
901 support, 20.4 is approximately as stable as 19.16, and probably faster
|
|
|
902 (due to additional optimization work.)
|
|
|
903
|
|
|
904 As of XEmacs 20.3, version 20 is @emph{the} supported version of
|
|
|
905 XEmacs. This means that 19.16 will optionally receive stability fixes
|
|
|
906 (if any), but that all the real development work will be done on the v20
|
|
|
907 tree.
|
|
|
908
|
|
|
909 The incompatible changes in XEmacs 20 include the additional byte-codes,
|
|
|
910 new primitive data types (@code{character}, @code{char-table}, and
|
|
|
911 @code{range-table}). This means that the character-integer equivalence
|
|
|
912 inherent to all the previous Emacs and XEmacs releases no longer
|
|
|
913 applies.
|
|
|
914
|
|
|
915 However, to avoid breaking old code, many functions that should normally
|
|
|
916 accept characters work with integers, and vice versa. For more
|
|
|
917 information, see the Lisp reference manual. Here is a relevant excerpt,
|
|
|
918 for your convenience.
|
|
|
919
|
|
|
920 @quotation
|
|
|
921 In XEmacs version 19, and in all versions of FSF GNU Emacs, a
|
|
|
922 @dfn{character} in XEmacs Lisp is nothing more than an integer.
|
|
|
923 This is yet another holdover from XEmacs Lisp's derivation from
|
|
|
924 vintage-1980 Lisps; modern versions of Lisp consider this equivalence
|
|
|
925 a bad idea, and have separate character types. In XEmacs version 20,
|
|
|
926 the modern convention is followed, and characters are their own
|
|
|
927 primitive types. (This change was necessary in order for @sc{mule},
|
|
|
928 i.e. Asian-language, support to be correctly implemented.)
|
|
|
929
|
|
|
930 Even in XEmacs version 20, remnants of the equivalence between
|
|
|
931 characters and integers still exist; this is termed the @dfn{char-int
|
|
|
932 confoundance disease}. In particular, many functions such as @code{eq},
|
|
|
933 @code{equal}, and @code{memq} have equivalent functions (@code{old-eq},
|
|
|
934 @code{old-equal}, @code{old-memq}, etc.) that pretend like characters
|
|
|
935 are integers are the same. Byte code compiled under any version 19
|
|
|
936 Emacs will have all such functions mapped to their @code{old-} equivalents
|
|
|
937 when the byte code is read into XEmacs 20. This is to preserve
|
|
|
938 compatibility -- Emacs 19 converts all constant characters to the equivalent
|
|
|
939 integer during byte-compilation, and thus there is no other way to preserve
|
|
|
940 byte-code compatibility even if the code has specifically been written
|
|
|
941 with the distinction between characters and integers in mind.
|
|
|
942
|
|
|
943 Every character has an equivalent integer, called the @dfn{character
|
|
|
944 code}. For example, the character @kbd{A} is represented as the
|
|
|
945 @w{integer 65}, following the standard @sc{ascii} representation of
|
|
|
946 characters. If XEmacs was not compiled with @sc{mule} support, the
|
|
|
947 range of this integer will always be 0 to 255 -- eight bits, or one
|
|
|
948 byte. (Integers outside this range are accepted but silently truncated;
|
|
|
949 however, you should most decidedly @emph{not} rely on this, because it
|
|
|
950 will not work under XEmacs with @sc{mule} support.) When @sc{mule}
|
|
|
951 support is present, the range of character codes is much
|
|
|
952 larger. (Currently, 19 bits are used.)
|
|
|
953
|
|
|
954 FSF GNU Emacs uses kludgy character codes above 255 to represent
|
|
|
955 keyboard input of @sc{ascii} characters in combination with certain
|
|
|
956 modifiers. XEmacs does not use this (a more general mechanism is
|
|
|
957 used that does not distinguish between @sc{ascii} keys and other
|
|
|
958 keys), so you will never find character codes above 255 in a
|
|
|
959 non-@sc{mule} XEmacs.
|
|
|
960
|
|
|
961 Individual characters are not often used in programs. It is far more
|
|
|
962 common to work with @emph{strings}, which are sequences composed of
|
|
|
963 characters.

1008 Original Mule supports the following input methods: Wnn4, Wnn6, Canna, SJ3
|
|
|
1009 and XIM. Interfaces for Wnn and SJ3 uses the @code{egg} user
|

1010 interface. Interface for Canna does not use @samp{egg}. I don't know
|
|
|
1011 about XIM. It is to support ATOK, of course, it may work for another
|
|
|
1012 servers.
|
|
|
1013
|
|
|
1014 Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
|
|
|
1015 university. It is a powerful and complex system. Wnn4 is free and Wnn6
|
|
|
1016 is not free.
|
|
|
1017
|
|
|
1018 Canna supports only Japanese. It is made by NEC. It is a simple and
|
|
|
1019 powerful system. Canna uses only grammar (Wnn uses grammar and
|
|
|
1020 probability between words), so I think Wnn is cleverer than Canna,
|
|
|
1021 however Canna users made a good grammar and dictionary. So for standard
|
|
|
1022 modern Japanese, Canna seems cleverer than Wnn4. In addition, the UNIX
|
|
|
1023 version of Canna is free (now there is a Microsoft Windows version).
|
|
|
1024
|
|
|
1025 SJ3 supports only Japanese. It is made by Sony. XIM supports was made
|
|
|
1026 to use ATOK (a major input method in personal computer world). XIM is
|
|
|
1027 the standard for accessing input methods bundled in Japanese versions of

1044 Egg and Canna. @samp{Boiled-egg} is a mode-less input method running on

1045 Egg. For Canna, @samp{canna.el} has a tiny boiled-egg like command,

1059 MULE and XEmacs are quite different. So the application

|
|
|
1211 sitting just to the right of the function you want explained. Eg. move
|
|
|
1212 the cursor to the SPACE between @code{interactive} and @samp{"*p"} and
|
|
|
1213 hit @kbd{C-h f} to see what the function @code{interactive} does. Doing
|
|
|
1214 this will tell you that the @code{*} requires a writable buffer, and
|
|
|
1215 @code{p} converts the prefix argument to a number, and
|
|
|
1216 @code{interactive} allows you to execute the command with @kbd{M-x}.

1237 expression which will in turn compute the value. We call this
|
|
|
1238 expression the @dfn{expansion} of the macro.
|
|
|
1239
|
|
|
1240 Macros can do this because they operate on the unevaluated expressions
|
|
|
1241 for the arguments, not on the argument values as functions do. They can
|
|
|
1242 therefore construct an expansion containing these argument expressions
|
|
|
1243 or parts of them.
|
|
|
1244
|
|
|
1245 Do not confuse the two terms with @dfn{keyboard macros}, which are
|
|
|
1246 another matter, entirely. A keyboard macro is a key bound to several
|
|
|
1247 other keys. Refer to manual for details.

1250 @unnumberedsubsec Q1.4.7: How come options saved with 19.13 don't work with 19.14 or later?
|
|
|
1251
|
|
|
1252 There's a problem with options of the form:
|
|
|
1253
|
|
|
1254 @lisp
|
|
|
1255 (add-spec-list-to-specifier (face-property 'searchm-field 'font)
|
|
|
1256 '((global (nil))))
|
|
|
1257 @end lisp
|
|
|
1258
|
|
|
1259 saved by a 19.13 XEmacs that causes a 19.14 XEmacs grief. You must
|
|
|
1260 delete these options. XEmacs 19.14 and later no longer write the
|
|
|
1261 options directly to @file{.emacs} which should allow us to deal with
|
|
|
1262 version incompatibilities better in the future.
|
|
|
1263
|
|
|
1264 Options saved under XEmacs 19.13 are protected by code that specifically
|
|
|
1265 requires a version 19 XEmacs. This won't be a problem unless you're
|
|
|
1266 using XEmacs v20. You should consider changing the code to read:
|
|
|
1267
|
|
|
1268 @lisp
|
|
|
1269 (cond
|
|
|
1270 ((and (string-match "XEmacs" emacs-version)
|
|
|
1271 (boundp 'emacs-major-version)
|
|
|
1272 (or (and (= emacs-major-version 19)
|
|
|
1273 (>= emacs-minor-version 12))
|
|
|
1274 (>= emacs-major-version 20)))
|
|

1275 ...

1330 @unnumberedsubsec Q2.0.1: Running XEmacs without installing
|
|
|
1331 The @file{INSTALL} file says that up to 108 MB of space is needed
|
|
|
1332 temporarily during installation! How can I just try it out?
|
|
|
1333
|
|
|
1334 XEmacs will run in place without requiring installation and copying of
|
|
|
1335 the Lisp directories, and without having to specify a special build-time
|
|
|
1336 flag. It's the copying of the Lisp directories that requires so much
|
|
|
1337 space. XEmacs is largely written in Lisp.
|
|
|
1338
|
|
|
1339 A good method is to make a shell alias for xemacs:
|
|
|
1340
|
|
|
1341 @example
|
|
|
1342 alias xemacs=/i/xemacs-20.2/src/xemacs
|
|
|
1343 @end example
|
|
|
1344
|
|
|
1345 (You will obviously use whatever directory you downloaded the source
|
|
|
1346 tree to instead of @file{/i/xemacs-20.2}).
|
|
|
1347
|
|
|
1348 This will let you run XEmacs without massive copying.

1359 The 45MB of space required by the installation directories can be
|
|
|
1360 reduced dramatically if desired. Gzip all the .el files. Remove all
|
|
|
1361 the packages you'll never want to use (or even ones you do like the two
|
|
|
1362 obsolete mailcrypts and Gnus 4 in 19.13). Remove the TexInfo manuals.
|
|
|
1363 Remove the Info (and use just hardcopy versions of the manual). Remove
|
|
|
1364 most of the stuff in etc. Remove or gzip all the source code. Gzip or
|
|
|
1365 remove the C source code. Configure it so that copies are not made of
|
|
|
1366 the support lisp. I'm not advocating any of these things, just pointing
|
|
|
1367 out ways to reduce the disk requirements if desired.
|
|
|
1368
|

1369 Now examine the space used by directory:

|
|
|
1378
|
|
|
1379 You need to keep these. XEmacs isn't stripped by default in
|
|
|
1380 installation, you should consider stripping. That will save you about
|
|
|
1381 5MB right there.

1446 These are all Emacs Lisp source code and bytecompiled object code. You
|
|
|
1447 may safely gzip everything named *.el here. You may remove any package
|
|
|
1448 you don't use. @emph{Nothing bad will happen if you delete a package
|
|
|
1449 that you do not use}. You must be sure you do not use it though, so be
|
|
|
1450 conservative at first.
|
|
|
1451
|
|
|
1452 Possible candidates for deletion include w3 (newer versions exist, or
|
|
|
1453 you may just use Lynx or Netscape for web browsing), games, hyperbole,
|
|
|
1454 mh-e, hm--html-menus (better packages exist), vm, viper, oobr, gnus (new
|
|
|
1455 versions exist), etc. Ask yourself, @emph{Do I ever want to use this
|
|
|
1456 package?} If the answer is no, then it is a candidate for removal.
|
|
|
1457
|
|
|
1458 First, gzip all the .el files. Then go about package by package and
|
|
|
1459 start gzipping the .elc files. Then run XEmacs and do whatever it is
|
|
|
1460 you normally do. If nothing bad happens, then delete the directory. Be
|
|
|
1461 conservative about deleting directories, and it would be handy to have a
|
|
|
1462 backup tape around in case you get too zealous.
|
|
|
1463
|
|
|
1464 @file{prim}, @file{modes}, @file{packages}, and @file{utils} are four
|
|
|
1465 directories you definitely do @strong{not} want to delete, although
|
|
|
1466 certain packages can be removed from them if you do not use them.
|
|
|
1467
|
|
|
1468 @example
|
|
|
1469 1972 /usr/local/lib/xemacs-19.13/info
|
|
|
1470 @end example
|
|
|
1471
|
|
|
1472 These are online texinfo sources. You may either gzip them or remove
|
|
|
1473 them. In either case, @kbd{C-h i} (info mode) will no longer work.
|
|
|
1474

1479 The 20MB achieved is less than half of what the full distribution takes up,

1529 @unnumberedsubsec Q2.0.3: Compiling XEmacs with Netaudio.
|
|
|
1530
|
|
|
1531 What is the best way to compile XEmacs with the netaudio system, since I
|
|
|
1532 have got the netaudio system compiled but installed at a weird place, I
|
|
|
1533 am not root. Also in the READMEs it does not say anything about
|
|
|
1534 compiling with the audioserver?
|
|
|
1535
|
|
|
1536 You should only need to add some stuff to the configure command line.
|
|
|
1537 To tell it to compile in netaudio support: @samp{--with-sound=both}, or
|
|
|
1538 @samp{--with-sound=nas} if you don't want native sound support for some
|
|
|
1539 reason.) To tell it where to find the netaudio includes and libraries:
|
|
|
1540
|
|
|
1541 @example
|
|
|
1542 --site-libraries=WHATEVER
|
|
|
1543 --site-includes=WHATEVER
|
|
|
1544 @end example
|
|
|
1545
|
|
|
1546 Then (fingers crossed) it should compile and it will use netaudio if you
|
|
|
1547 have a server running corresponding to the X server. The netaudio server
|
|
|
1548 has to be there when XEmacs starts. If the netaudio server goes away and
|
|
|
1549 another is run, XEmacs should cope (fingers crossed, error handling in
|
|
|
1550 netaudio isn't perfect).
|
|
|
1551
|
|
|
1552 BTW, netaudio has been renamed as it has a name clash with something
|
|
|
1553 else, so if you see references to NAS or Network Audio System, it's the
|
|
|
1554 same thing. It also might be found at

1739 That's correct [The SunOS 4.1.3 precompiled binaries don't do name

|
|

1741 (that DNS thing was apparently only a passing fad, right?), the stock

1746 The best solution is to compile it yourself; the configure script will

1757 Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
|
|
|
1758 link gives you a bare-boned emacs (called temacs). temacs is then run,
|
|
|
1759 preloading some of the lisp files. The result is then dumped into a new
|
|
|
1760 executable, named xemacs, which will contain all of the preloaded lisp
|
|
|
1761 functions and data.
|
|
|
1762
|
|
|
1763 Now, during the dump itself, the executable (code+data+symbols) is
|
|
|
1764 written on disk using a special unexec() function. This function is
|
|
|
1765 obviously heavily system dependent. And on some systems, it leads to an
|
|
|
1766 executable which, although valid, cannot be stripped without damage. If
|
|
|
1767 memory serves, this is especially the case for AIX binaries. On other
|
|
|
1768 architecture it might work OK.
|
|
|
1769
|
|
|
1770 The Right Way to strip the emacs binary is to strip temacs prior to
|
|
|
1771 dumping xemacs. This will always work, although you can do that only if
|
|
|
1772 you install from sources (as temacs is @file{not} part of the binary
|
|
|
1773 kits).

1847 @unnumberedsubsec Q2.1.1: Help! XEmacs just crashed on me!
|
|
|
1848
|
|
|
1849 First of all, don't panic. Whenever XEmacs crashes, it tries extremely
|
|
|
1850 hard to auto-save all of your files before dying. (The main time that
|
|
|
1851 this will not happen is if the machine physically lost power or if you
|
|
|
1852 killed the XEmacs process using @code{kill -9}). The next time you try
|
|
|
1853 to edit those files, you will be informed that a more recent auto-save
|
|
|
1854 file exists. You can use @kbd{M-x recover-file} to retrieve the
|
|
|
1855 auto-saved version of the file.
|
|
|
1856
|
|
|
1857 Starting with 19.14, you may use the command @kbd{M-x recover-session}
|
|
|
1858 after a crash to pick up where you left off.
|
|
|
1859
|
|
|
1860 Now, XEmacs is not perfect, and there may occasionally be times, or
|
|
|
1861 particular sequences of actions, that cause it to crash. If you can
|
|
|
1862 come up with a reproducible way of doing this (or even if you have a
|
|
|
1863 pretty good memory of exactly what you were doing at the time), the
|
|
|
1864 maintainers would be very interested in knowing about it. Post a
|
|
|
1865 message to comp.emacs.xemacs or send mail to @email{crashes@@xemacs.org}.
|
|
|
1866 Please note that the @samp{crashes} address is exclusively for crash
|
|
|
1867 reports.
|
|
|
1868
|
|
|
1869 If at all possible, include a stack backtrace of the core dump that was
|
|
|
1870 produced. This shows where exactly things went wrong, and makes it much
|
|
|
1871 easier to diagnose problems. To do this, you need to locate the core
|
|
|
1872 file (it's called @file{core}, and is usually sitting in the directory
|
|
|
1873 that you started XEmacs from, or your home directory if that other
|
|
|
1874 directory was not writable). Then, go to that directory and execute a
|
|
|
1875 command like:
|
|
|
1876
|
|
|
1877 @example
|
|
|
1878 gdb `which xemacs` core
|
|
|
1879 @end example
|
|
|
1880
|
|
|
1881 and then issue the command @samp{where} to get the stack backtrace. You
|
|
|
1882 might have to use @code{dbx} or some similar debugger in place of
|
|
|
1883 @code{gdb}. If you don't have any such debugger available, complain to
|
|
|
1884 your system administrator.
|
|
|
1885
|
|
|
1886 It's possible that a core file didn't get produced, in which case you're
|
|
|
1887 out of luck. Go complain to your system administrator and tell him not
|
|
|
1888 to disable core files by default. Also @xref{Q2.1.15}, for tips and
|
|
|
1889 techniques for dealing with a debugger.

|

1951 How do I get rid of them?
|
|
|
1952
|
|
|
1953 There are two causes of this problem. The first usually only strikes
|
|
|
1954 people using the prebuilt binaries. The culprit in both cases is the
|
|
|
1955 file @file{XKeysymDB}.
|
|
|
1956
|
|
|
1957 @itemize @bullet
|
|
|
1958 @item
|
|
|
1959 The binary cannot find the @file{XKeysymDB} file. The location is
|
|
|
1960 hardcoded at compile time so if the system the binary was built on puts
|
|
|
1961 it a different place than your system does, you have problems. To fix,
|
|
|
1962 set the environment variable @var{XKEYSYMDB} to the location of the
|
|
|
1963 @file{XKeysymDB} file on your system or to the location of the one
|
|
|
1964 included with XEmacs which should be at
|
|
|
1965 @iftex
|
|
|
1966 @*
|
|

1967 @end iftex

1970 @item
|
|
|
1971 The binary is finding the XKeysymDB but it is out-of-date on your system
|
|
|
1972 and does not contain the necessary lines. Either ask your system
|
|
|
1973 administrator to replace it with the one which comes with XEmacs (which
|
|
|
1974 is the stock R6 version and is backwards compatible) or set your

1981 How can I avoid the startup warnings about deducing proper fonts?
|
|
|
1982
|
|

1983 This is highly dependent on your installation, but try with the

|

1985
|
|
|
1986 @format

1987 -adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
|
|
|
1988 @end format
|
|
|
1989
|
|
|
1990 More precisely, do the following in your resource file:
|
|
|
1991
|
|
|
1992 @format
|
|
|
1993 Emacs.default.attributeFont: \
|
|
|

|
|
|
1995 @end format
|
|
|
1996
|
|
|
1997 If you just don't want to see the @samp{*Warnings*} buffer at startup
|
|
|
1998 time, you can set this:
|
|
|
1999

2245 @unnumberedsubsec Q2.1.15: How to Debug an XEmacs problem with a debugger
|
|
|
2246
|
|
|
2247 If XEmacs does crash on you, one of the most productive things you can
|
|
|
2248 do to help get the bug fixed is to poke around a bit with the debugger.
|
|
|
2249 Here are some hints:
|
|
|
2250
|
|
|
2251 @itemize @bullet
|
|
|
2252 @item
|
|
|
2253 First of all, if the crash is at all reproducible, consider very
|
|
|
2254 strongly recompiling your XEmacs with debugging symbols, with no
|
|
|
2255 optimization, and with the configure options @samp{--debug=yes} and
|
|
|
2256 @samp{--error-checking=all}. This will make your XEmacs run somewhat
|
|
|
2257 slower but make it a lot more likely to catch the problem earlier
|
|
|
2258 (closer to its source), and a lot easier to determine what's going on
|
|
|
2259 with a debugger.
|
|
|
2260
|
|
|
2261 @item
|
|
|
2262 If you're able to run XEmacs under a debugger and reproduce the crash
|
|
|
2263 (if it's inconvenient to do this because XEmacs is already running or is
|
|
|
2264 running in batch mode as part of a bunch of scripts, consider attaching
|
|
|
2265 to the existing process with your debugger; most debuggers let you do
|
|
|
2266 this by substituting the process ID for the core file when you invoke
|
|
|
2267 the debugger from the command line, or by using the @code{attach}
|
|
|
2268 command or something similar), here are some things you can do:
|
|
|
2269
|
|
|
2270 @item
|
|
|
2271 If XEmacs is hitting an assertion failure, put a breakpoint on
|
|
|
2272 @code{assert_failed()}.
|
|
|
2273
|
|
|
2274 @item
|
|
|
2275 If XEmacs is hitting some weird Lisp error that's causing it to crash
|
|
|
2276 (e.g. during startup), put a breakpoint on @code{signal_1()}---this is
|
|
|
2277 declared static in eval.c.
|
|
|
2278
|
|
|
2279 @item
|
|
|
2280 Internally, you will probably see lots of variables that hold objects of
|
|
|
2281 type @code{Lisp_Object}. These are exactly what they appear to be,
|
|
|
2282 i.e. references to Lisp objects. Printing them out with the debugger
|
|
|
2283 probably won't be too useful---you'll likely just see a number. To
|
|
|
2284 decode them, do this:
|
|
|
2285
|
|
|
2286 @example
|
|
|
2287 call debug_print (OBJECT)
|
|
|
2288 @end example
|
|
|
2289
|
|
|
2290 where @var{OBJECT} is whatever you want to decode (it can be a variable,
|
|
|
2291 a function call, etc.). This will print out a readable representation
|
|
|
2292 on the TTY from which the xemacs process was invoked.
|
|
|
2293
|
|
|
2294 @item
|
|
|
2295 If you want to get a Lisp backtrace showing the Lisp call
|
|
|
2296 stack, do this:
|
|
|
2297
|
|
|
2298 @example
|
|
|
2299 call debug_backtrace ()
|
|
|
2300 @end example
|
|
|
2301
|
|
|
2302 @item
|
|
|
2303 Using @code{debug_print} and @code{debug_backtrace} has two
|
|
|
2304 disadvantages - it can only be used with a running xemacs process, and
|
|
|
2305 it cannot display the internal C structure of a Lisp Object. Even if
|
|
|
2306 all you've got is a core dump, all is not lost.
|
|
|
2307
|
|
|
2308 If you're using GDB, there are some macros in the file
|
|
|
2309 @file{src/gdbinit} in the XEmacs source distribution that should make it
|
|
|
2310 easier for you to decode Lisp objects. Copy this file to
|
|
|
2311 @file{~/.gdbinit}, or @code{source} it from @file{~/.gdbinit}, and use
|
|
|
2312 the macros defined therein. In particular, use the @code{pobj} macro to
|
|
|
2313 print the internal C representation of a lisp object. This will work
|
|
|
2314 with a core file or not-yet-run executable. The aliases @code{ldp} and
|
|
|
2315 @code{lbt} are provided for conveniently calling @code{debug_print} and
|
|
|
2316 @code{debug_backtrace}.
|
|
|
2317
|
|
|
2318 If you are using Sun's @file{dbx} debugger, there is an equivalent file
|
|
|
2319 @file{src/dbxrc} to copy to or source from @file{~/.dbxrc}.
|
|
|
2320
|
|
|
2321 @item
|
|
|
2322 If you're using a debugger to get a C stack backtrace and you're seeing
|
|
|
2323 stack traces with some of the innermost frames mangled, it may be due to
|
|
|
2324 dynamic linking. (This happens especially under Linux.) Consider
|
|
|
2325 reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
|
|
|
2326 Linux), stack backtraces of core dumps will have the frame where the
|
|
|
2327 fatal signal occurred mangled; if you can obtain a stack trace while
|
|
|
2328 running the XEmacs process under a debugger, the stack trace should be
|
|
|
2329 clean.

|
|

|
|
|
2331 @email{1CMC3466@@ibm.mtsac.edu, Curtiss} suggests upgrading to ld.so version 1.8

|
|
2335 If you're using a debugger to get a C stack backtrace and you're
|
|
|
2336 getting a completely mangled and bogus stack trace, it's probably due to
|
|
|
2337 one of the following:

|

2342 do this---it doesn't accomplish anything except to save a bit of disk
|
|
|
2343 space, and makes debugging much much harder.
|
|
|
2344
|
|
|
2345 @item
|
|
|
2346 Your stack is getting trashed. Debugging this is hard; you have to do a
|
|
|
2347 binary-search type of narrowing down where the crash occurs, until you
|
|
|
2348 figure out exactly which line is causing the problem. Of course, this
|
|
|
2349 only works if the bug is highly reproducible.
|
|
|
2350
|
|
|
2351 @item
|
|
|
2352 If your stack trace has exactly one frame in it, with address 0x0, this
|
|
|
2353 could simply mean that XEmacs attempted to execute code at that address,
|
|
|
2354 e.g. through jumping to a null function pointer. Unfortunately, under
|
|
|
2355 those circumstances, GDB under Linux doesn't know how to get a stack
|
|
|
2356 trace. (Yes, this is the third Linux-related problem I've mentioned. I
|
|
|
2357 have no idea why GDB under Linux is so bogus. Complain to the GDB
|
|
|
2358 authors, or to comp.os.linux.development.system). Again, you'll have to
|
|
|
2359 use the narrowing-down process described above.

2362 If you compiled 19.14 with @samp{--debug} (or by default in later

2364 you'll have something useful.

2428 For the record, compiling on hpux 10.10 leads to a hang in Gnus when

2434 10.10, and... the hang is now gone.

2435
|

2436 As far as configure goes, this will be a bit tricky: @code{BROKEN_SIGIO}
|

2437 is needed on 10.10, but @strong{not} on 10.01: if I run my 10.01 binary

2477 @unnumberedsubsec Q2.1.19: XEmacs does not follow the local timezone.
|
|
|
2478
|
|
|
2479 When using one of the prebuilt binaries many users have observed that
|
|
|
2480 XEmacs uses the timezone under which it was built, but not the timezone
|
|
|
2481 under which it is running. The solution is to add:
|
|
|
2482
|
|
|
2483 @lisp
|
|
|
2484 (set-time-zone-rule "MET")
|
|
|
2485 @end lisp
|
|
|
2486
|
|
|
2487 to your @file{.emacs} or the @file{site-start.el} file if you can.
|
|
|
2488 Replace @code{MET} with your local timezone.

2513 Two things you can do:
|
|
|
2514
|
|
|
2515 1) C level:
|
|
|
2516
|
|
|
2517 When you see it going mad like this, you might want to use gdb from an
|
|
|
2518 'xterm' to attach to the running process and get a stack trace. To do
|
|
|
2519 this just run:
|
|
|
2520
|
|
|
2521 @example
|
|
|
2522 gdb /path/to/xemacs/xemacs ####
|
|
|
2523 @end example
|
|
|
2524
|
|
|
2525 Where @code{####} is the process id of your xemacs, instead of
|
|
|
2526 specifying the core. When gdb attaches, the xemacs will stop [1] and
|
|
|
2527 you can type `where' in gdb to get a stack trace as usual. To get
|
|
|
2528 things moving again, you can just type `quit' in gdb. It'll tell you
|
|
|
2529 the program is running and ask if you want to quit anyways. Say 'y' and
|
|
|
2530 it'll quit and have your emacs continue from where it was at.
|
|
|
2531
|
|
|
2532 2) Lisp level:
|
|
|
2533
|
|
|
2534 Turn on debug-on-quit early on. When you think things are going slow
|
|
|
2535 hit C-g and it may pop you in the debugger so you can see what routine
|
|
|
2536 is running. Press `c' to get going again.
|
|
|
2537
|
|
|
2538 debug-on-quit doesn't work if something's turned on inhibit-quit or in
|
|
|
2539 some other strange cases.

2813

|

2814 Starting with XEmacs 20.2 there is new system 'Customize' for customizing

|
|
2815 XEmacs options.
|
|
|
2816
|
|
|
2817 You can access @code{Customize} from the @code{Options} menu
|
|
|
2818 or invoking one of customize commands by typing eg.
|
|
|
2819 @kbd{M-x customize}, @kbd{M-x customize-face},
|
|
|
2820 @kbd{M-x customize-variable} or @kbd{M-x customize-apropos}.
|
|
|
2821
|
|
|
2822 Starting with XEmacs 20.3 there is also new `browser' mode for Customize.

2923 @unnumberedsubsec Q3.1.7: @samp{xemacs -name junk} doesn't work?
|
|
|
2924
|
|
|
2925 When I run @samp{xterm -name junk}, I get an xterm whose class name
|
|
|
2926 according to xprop, is @samp{junk}. This is the way it's supposed to
|
|
|
2927 work, I think. When I run @samp{xemacs -name junk} the class name is
|
|
|
2928 not set to @samp{junk}. It's still @samp{emacs}. What does
|
|
|
2929 @samp{xemacs -name} really do? The reason I ask is that my window
|
|
|
2930 manager (fvwm) will make a window sticky and I use XEmacs to read my
|
|
|
2931 mail. I want that XEmacs window to be sticky, without having to use the
|
|
|
2932 window manager's function to set the window sticky. What gives?
|
|
|
2933
|
|
|
2934 @samp{xemacs -name} sets the application name for the program (that is,
|
|
|
2935 the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
|
|
|
2936 is the same as making a copy of the executable with that new name. The
|
|
|
2937 @code{WM_CLASS} property on each frame is set to the frame-name, and the
|
|
|
2938 application-class. So, if you did @samp{xemacs -name FOO} and then
|
|
|
2939 created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
|
|
|
2940 @code{( "BAR", "Emacs")}. However, the resource hierarchy for this
|
|
|
2941 widget would be:
|
|
|
2942
|
|
|
2943 @example
|
|
|
2944 Name: FOO .shell .container .BAR
|
|
|
2945 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2946 @end example
|
|
|
2947
|
|
|
2948 instead of the default
|
|
|
2949
|
|
|
2950 @example
|
|
|
2951 Name: xemacs.shell .container .emacs
|
|
|
2952 Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
|
|
|
2953 @end example
|
|
|
2954
|
|
|
2955
|
|
|
2956 It is arguable that the first element of WM_CLASS should be set to the
|
|
|
2957 application-name instead of the frame-name, but I think that's less
|
|
|
2958 flexible, since it does not give you the ability to have multiple frames
|
|
|
2959 with different WM_CLASS properties. Another possibility would be for
|
|
|
2960 the default frame name to come from the application name instead of
|
|
|
2961 simply being @samp{emacs}. However, at this point, making that change
|
|
|
2962 would be troublesome: it would mean that many users would have to make
|
|
|
2963 yet another change to their resource files (since the default frame name
|
|
|
2964 would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
|
|
|
2965 the executable happened to be named), so we'd rather avoid it.
|
|
|
2966
|
|
|
2967 To make a frame with a particular name use:
|
|
|
2968
|
|
|
2969 @lisp
|
|
|
2970 (make-frame '((name . "the-name")))

3064 @unnumberedsubsec Q3.2.4: How can I limit color map usage?
|
|
|
3065
|
|
|
3066 I'm using Netscape (or another color grabber like XEmacs);
|
|
|
3067 is there anyway to limit the number of available colors in the color map?
|
|
|
3068
|
|
|
3069 XEmacs 19.13 didn't have such a mechanism (unlike netscape, or other
|
|
|
3070 color-hogs). One solution is to start XEmacs prior to netscape, since
|
|
|
3071 this will prevent Netscape from grabbing all colors (but Netscape will
|
|
|
3072 complain). You can use the flags for Netscape, like -mono, -ncols <#>
|
|
|
3073 or -install (for mono, limiting to <#> colors, or for using a private
|
|
|
3074 color map). Since Netscape will take the entire colormap and never
|
|
|
3075 release it, the only reasonable way to run it is with @samp{-install}.
|
|
|
3076
|
|
|
3077 If you have the money, another solution would be to use a truecolor or
|
|
|
3078 direct color video.
|
|
|
3079
|
|
|
3080 Starting with XEmacs 19.14, XEmacs uses the closest available color if
|
|
|
3081 the colormap is full, so it's O.K. now to start Netscape first.

|

3085

3086 XEmacs tries to automatically determine whether your tty supports color,
|
|
|
3087 but sometimes guesses wrong. In that case, you can make XEmacs Do The
|
|
|
3088 Right Thing using this Lisp code:
|
|
|

|
|
|
3090 @lisp

|
|
|
3101 There are several ways to do it. For example, you could specify a
|
|
|
3102 default pixmap image to use in your @file{~/.Xresources}, e.g.,
|
|
|
3103
|
|
|
3104
|
|
|
3105 @example
|
|
|
3106 Emacs*EmacsFrame.default.attributeBackgroundPixmap: /path/to/image.xpm
|
|
|
3107 @end example
|
|
|
3108
|
|
|
3109
|
|
|
3110 and then reload ~/.Xresources and restart XEmacs. Alternatively,
|
|
|
3111 since each face can have its own pixmap background, a better way
|
|
|
3112 would be to set a face's pixmap within your XEmacs init file, e.g.,
|
|
|
3113
|
|
|
3114 @lisp
|
|
|
3115 (set-face-background-pixmap 'default "/path/to/image.xpm")

3116 (set-face-background-pixmap 'bold "/path/to/another_image.xpm")
|
|
|
3117 @end lisp
|
|
|
3118
|
|
|
3119 and so on. You can also do this interactively via @kbd{M-x edit-faces}.

3212 @unnumberedsubsec Q3.3.5: How can one change the modeline color based on the mode used?
|
|
|
3213
|
|
|
3214 You can use something like the following:
|
|
|
3215
|
|
|
3216 @lisp
|
|
|
3217 (add-hook 'lisp-mode-hook
|

|
3219 (set-face-background 'modeline "red" (current-buffer))))
|
|
|
3220 @end lisp
|
|
|
3221
|
|
|
3222 Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline
|
|
|
3223 colors change from the default set in your @file{.emacs}. The change
|
|
|
3224 will only be made in the buffer you just entered (which contains the
|
|
|
3225 Lisp file you are editing) and will not affect the modeline colors
|
|
|
3226 anywhere else.
|
|
|
3227
|
|
|
3228 Notes:
|
|
|
3229
|

|
3230 @itemize @bullet
|
|
|
3231
|
|
|
3232 @item
|
|
|
3233 The hook is the mode name plus @code{-hook}. eg. c-mode-hook,
|
|
|
3234 c++-mode-hook, emacs-lisp-mode-hook (used for your @file{.emacs} or a
|
|
|
3235 @file{xx.el} file), lisp-interaction-mode-hook (the @samp{*scratch*}
|
|
|
3236 buffer), text-mode-hook, etc.
|
|
|
3237
|
|
|
3238 @item
|
|
|
3239 Be sure to use @code{add-hook}, not @code{(setq c-mode-hook xxxx)},
|
|
|
3240 otherwise you will erase anything that anybody has already put on the
|
|
|
3241 hook.
|
|
|
3242
|
|
|
3243 @item
|
|
|
3244 You can also do @code{(set-face-font 'modeline @var{font})},
|
|
|
3245 eg. @code{(set-face-font 'modeline "*bold-r-normal*140-100-100*"
|
|
|
3246 (current-buffer))} if you wish the modeline font to vary based on the
|
|
|
3247 current mode.
|
|
|
3248 @end itemize
|
|
|
3249

3250 This works in 19.15 as well, but there are additional modeline faces,

3251 @code{modeline-buffer-id}, @code{modeline-mousable}, and
|

|
|
|
3278 @unnumberedsubsec Q3.5.1: How can I bind complex functions (or macros) to keys?
|
|
|
3279
|
|
|
3280 As an example, say you want the @kbd{paste} key on a Sun keyboard to
|
|
|
3281 insert the current Primary X selection at point. You can accomplish this
|
|
|
3282 with:
|
|
|
3283
|
|
|
3284 @lisp
|
|
|
3285 (define-key global-map [f18] 'x-insert-selection)
|
|
|
3286 @end lisp
|
|
|
3287
|
|
|
3288 However, this only works if there is a current X selection (the
|
|
|
3289 selection will be highlighted). The functionality I like is for the
|
|
|
3290 @kbd{paste} key to insert the current X selection if there is one,
|
|
|
3291 otherwise insert the contents of the clipboard. To do this you need to
|
|
|
3292 pass arguments to @code{x-insert-selection}. This is done by wrapping
|
|
|
3293 the call in a 'lambda form:
|
|
|
3294
|
|
|
3295 @lisp
|
|
|
3296 (global-set-key [f18]
|
|
|
3297 (lambda () (interactive) (x-insert-selection t nil)))
|
|
|
3298 @end lisp
|
|
|
3299
|
|
|
3300 This binds the f18 key to a @dfn{generic} functional object. The
|
|
|
3301 interactive spec is required because only interactive functions can be
|
|
|
3302 bound to keys.
|
|
|
3303
|
|
|
3304 For the FAQ example you could use:
|
|
|
3305
|
|
|
3306 @lisp
|
|
|
3307 (global-set-key [(control ?.)]
|
|
|
3308 (lambda () (interactive) (scroll-up 1)))
|
|
|
3309 (global-set-key [(control ? ;)]
|
|
|
3310 (lambda () (interactive) (scroll-up -1)))
|
|
|
3311 @end lisp
|
|
|
3312
|
|
|
3313 This is fine if you only need a few functions within the lambda body.
|
|
|
3314 If you're doing more it's cleaner to define a separate function as in
|
|
|
3315 question 3.5.3 (@pxref{Q3.5.3}).

3364
|

3365 However, some modes explicitly bind @kbd{Delete}, so you would need to
|
|
|
3366 add a hook that does @code{local-set-key} for them. If what you want to
|
|
|
3367 do is make the Backspace and Delete keys work more PC/Motif-like, then
|
|

3368 take a look at the @file{delbs.el} package.
|
|
|
3369
|
|
|
3370 New in XEmacs 19.14 is a variable called @code{key-translation-map}
|
|
|
3371 which makes it easier to bind @kbd{Delete}. @file{delbs.el} is a

3372 good example of how to do this correctly.

3437 enable it by setting the variable @code{x-allow-sendevents} to t. You

3454 It depends upon your X server.
|
|
|
3455
|
|
|
3456 Generally, the simplest way is to define a key as Multi_key with
|
|
|
3457 xmodmap, e.g.
|
|
|
3458 @c hey, show some respect, willya -- there's xkeycaps, isn't there? --
|
|
|
3459 @c chr ;)
|
|
|
3460 @example
|
|
|
3461 xmodmap -e 'keycode 0xff20 = Multi_key'
|
|
|
3462 @end example
|
|
|
3463
|
|
|
3464 You will need to pick an appropriate keycode. Use xev to find out the
|
|
|
3465 keycodes for each key.
|
|
|
3466
|
|
|
3467 [NB: On a `Windows' keyboard, recent versions of XFree86 automatically
|
|
|
3468 define the right `Windows' key as Multi_key'.]
|
|
|
3469
|
|
|
3470 Once you have Multi_key defined, you can use e.g.
|
|
|
3471 @example
|
|
|
3472 Multi a ' => á
|
|
|
3473 Multi e " => ë
|
|
|
3474 Multi c , => ç
|
|
|
3475 @end example
|
|
|
3476
|
|
|
3477 etc.
|
|
|
3478
|
|
|
3479 Also, recent versions of XFree86 define various AltGr-<key>
|
|
|
3480 combinations as dead keys, i.e.
|
|
|
3481 @example
|
|
|
3482 AltGr [ => dead_diaeresis
|
|
|
3483 AltGr ] => dead_tilde
|
|
|
3484 AltGr ; => dead_acute
|
|
|
3485 @end example
|
|
|
3486 etc.
|
|
|
3487
|
|
|
3488 Running @samp{xmodmap -pk} will list all of the defined keysyms.

3506 for GNU Emacs syntax like:

3521 (require 'delbs)
|
|

3523

3524 This will give you the functions @code{delbs-enable-delete-forward} to
|
|
|
3525 set things up, and @code{delbs-disable-delete-forward} to revert to
|
|
|
3526 ``normal'' behavior. Note that @code{delbackspace} package is obsolete.
|
|
|
3527
|
|
|
3528 Starting with XEmacs-20.3 better solution is to set variable
|
|
|
3529 @code{delete-key-deletes-forward} to t. You can also change this with
|
|

3530 Customize. Select from the @code{Options} menu

3750 you can see what area is being yanked. If you start working, though, it

3751 will immediately complete its operation. In other words, it will only

3804 I am trying to use a resource like @code{Emacs*menubar*font} to set the

|
|
|
3806
|
|
|
3807 If you are using the real Motif menubar, this resource is not

3843 There are redisplay bugs in 19.14 that may make the preceding result in

3844 a messed-up display, especially for frames with multiple windows. You

|
|
|
3853 @unnumberedsubsec Q3.9.1: How can I disable the scrollbar?
|
|
|
3854
|
|
|
3855 To disable them for all frames, add the following line to
|
|
|
3856 your @file{.Xdefaults}:
|
|
|
3857
|
|
|
3858 @example
|
|
|
3859 Emacs.scrollBarWidth: 0
|
|
|
3860 @end example
|
|
|
3861
|
|
|
3862 Or select from the @code{Options} menu @code{Frame Appearance->Scrollbars}.
|
|
|
3863 Remember to save options.
|
|
|
3864
|
|
|
3865 To turn the scrollbar off on a per-frame basis, use the following
|
|
|
3866 function:
|
|
|
3867
|
|
|
3868 @lisp
|
|
|
3869 (set-specifier scrollbar-width 0 (selected-frame))
|
|
|
3870 @end lisp
|
|
|
3871
|
|
|
3872 You can actually turn the scrollbars on at any level you want by
|
|
|
3873 substituting for (selected-frame) in the above command. For example, to
|
|
|
3874 turn the scrollbars off only in a single buffer:
|
|
|
3875
|
|
|
3876 @lisp
|
|
|
3877 (set-specifier scrollbar-width 0 (current-buffer))
|
|
|
3878 @end lisp
|
|
|
3879
|
|
|
3880 In XEmacs versions prior to 19.14, you had to use the hairier construct:
|
|
|
3881
|
|
|
3882 @lisp
|
|
|
3883 (set-specifier scrollbar-width (cons (selected-frame) 0))

3892 ! Motif scrollbars
|
|
|
3893

3894 Emacs*XmScrollBar.Background: skyblue

3896
|

|
|
|
3898
|
|
|
3899 Emacs*Scrollbar.Foreground: skyblue
|
|
|
3900 Emacs*Scrollbar.Background: lightgray
|
|
|
3901 @end example
|
|
|
3902
|
|
|
3903 Note the capitalization of @code{Scrollbar} for the Athena widget.

|
|
|
3907
|
|
|
3908 When I move the scrollbar in an XEmacs window, it moves the point as
|
|
|
3909 well, which should not be the default behavior. Is this a bug or a
|
|
|
3910 feature? Can I disable it?
|
|
|
3911
|
|
|
3912 The current behavior is a feature, not a bug. Point remains at the same
|
|
|
3913 buffer position as long as that position does not scroll off the screen.
|
|
|
3914 In that event, point will end up in either the upper-left or lower-left
|
|
|
3915 hand corner.
|
|
|
3916
|
|

3917 This cannot be changed.

|
|
|
3921
|
|
|
3922 By the same token, how can I turn it off in specific modes?
|
|
|
3923
|
|
|
3924 To do this, add to your @file{.emacs} file:
|
|
|
3925
|
|
|
3926 @lisp
|
|
|
3927 (require 'auto-show)
|
|
|
3928 @end lisp
|
|
|
3929
|
|
|
3930 Then do @code{(setq truncate-lines t)} in the mode-hooks for any modes
|
|
|
3931 in which you want lines truncated.
|
|
|
3932
|
|
|
3933 More precisely: If @code{truncate-lines} is nil, horizontal scrollbars
|
|
|
3934 will never appear. Otherwise, they will appear only if the value of
|
|
|
3935 @code{scrollbar-height} for that buffer/window/etc. is non-zero. If you
|
|
|
3936 do
|
|
|
3937
|
|
|
3938 @lisp
|
|
|
3939 (set-specifier scrollbar-height 0)
|
|
|
3940 @end lisp
|
|
|
3941
|
|
|
3942 then horizontal scrollbars will not appear in truncated buffers unless
|
|
|
3943 the package specifically asked for them.
|
|
|
3944
|
|
|
3945 Automatic horizontal scrolling is now standard, starting with 19.14.

|
|
|
3950
|
|

3951 The @code{zmacs} mode allows for what some might call gratuitous
|
|
|
3952 highlighting for selected regions (either by setting mark or by using
|
|
|
3953 the mouse). This is the default behavior. To turn off, add the

3954 following line to your @file{.emacs} file:
|
|

3955
|
|
|
3956 @lisp

|

|
3961 from the @code{Options} menu @code{Customize->Emacs->Editing->Basics->Zmacs
|
|
|
3962 Regions} or type @kbd{M-x customize @key{RET} editing-basics @key{RET}}.
|
|

3963
|
|

3971 the typed text replaces the selected text, similar to Motif.

3972
|

|
3973 You want to use something called @dfn{pending delete}. Pending delete
|
|
|
3974 is what happens when you select a region (with the mouse or keyboard)
|
|
|
3975 and you press a key to replace the selected region by the key you typed.
|
|

3976 Usually backspace kills the selected region.

4123 One possibility is to use procmail to split your mail before it gets to

4124 VM. I prefer this personally, since there are many strange and

|
|
4125 wonderful things one can do with procmail. Procmail may be found at

|
|
|
4224
|
|
|
4225 @quotation
|
|
|
4226 rmail and VM get new mail from @file{/usr/spool/mail/$USER} using a
|
|
|
4227 program called @code{movemail}. This program interlocks with
|
|
|
4228 @code{/bin/mail} using the protocol defined by @code{/bin/mail}.
|
|
|
4229
|
|
|
4230 There are two different protocols in general use. One of them uses the
|
|
|
4231 @code{flock} system call. The other involves creating a lock file;
|
|
|
4232 @code{movemail} must be able to write in @file{/usr/spool/mail} in order
|
|
|
4233 to do this. You control which one is used by defining, or not defining,
|
|
|
4234 the macro @code{MAIL_USE_FLOCK} in @file{config.h} or the m- or s- file
|
|
|
4235 it includes.
|
|
|
4236
|
|
|
4237 @strong{IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
|
|
|
4238 SYSTEM, YOU CAN LOSE MAIL!}
|
|
|
4239
|
|
|
4240 If your system uses the lock file protocol, and fascist restrictions
|
|
|
4241 prevent ordinary users from writing the lock files in
|
|
|
4242 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a
|
|
|
4243 suitable group such as @samp{mail}. You can use these commands (as
|
|
|
4244 root):
|
|
|
4245
|
|
|
4246 @example
|
|
|
4247 chgrp mail movemail
|
|
|
4248 chmod 2755 movemail
|
|
|
4249 @end example
|

4250
|
|
|
4251 If your system uses the lock file protocol, and fascist restrictions
|
|
|
4252 prevent ordinary users from writing the lock files in
|
|
|
4253 @file{/usr/spool/mail}, you may need to make @code{movemail} setgid to a
|
|
|
4254 suitable group such as @code{mail}. To do this, use the following
|
|
|
4255 commands (as root) after doing the make install.
|
|
|
4256
|
|
|
4257 @example
|
|
|
4258 chgrp mail movemail
|
|
|
4259 chmod 2755 movemail
|
|
|
4260 @end example
|
|
|
4261
|
|
|
4262 Installation normally copies movemail from the build directory to an
|
|
|
4263 installation directory which is usually under @file{/usr/local/lib}.
|
|
|
4264 The installed copy of @code{movemail} is usually in the directory
|
|
|
4265 @file{/usr/local/lib/emacs/VERSION/TARGET}. You must change the group
|
|
|
4266 and mode of the installed copy; changing the group and mode of the build
|
|
|
4267 directory copy is ineffective.

|
|
|
4381
|
|
|
4382 The toolbar code to start Gnus opens the new frame---and it's a feature
|
|
|
4383 rather than a bug. If you don't like it, but would still like to click
|
|
|
4384 on the seemly icon, use the following code:
|
|
|
4385
|
|
|
4386 @lisp
|
|
|
4387 (defun toolbar-news ()
|
|
|
4388 (gnus))
|
|
|
4389 @end lisp
|
|
|
4390
|
|
|
4391 It will redefine the callback function of the icon to just call
|
|
|
4392 @code{gnus}, without all the fancy frame stuff.

|

4444
|
|

4445 TM stands for @dfn{Tools for MIME} and not Tiny MIME. TM integrates
|
|
|
4446 with all major XEmacs packages like Gnus (all flavors), VM, MH-E, and
|
|
|
4447 mailcrypt. It provides totally transparent and trouble-free MIME
|
|
|
4448 support. When appropriate a message will be decoded in place in an
|
|
|
4449 XEmacs buffer.
|
|
|
4450
|
|
|
4451 TM now comes as a package with XEmacs 19.16 and XEmacs 20.2.
|

4452

4645
|
|
|
4646 InfoDock is an integrated productivity toolset, mainly aimed at
|
|
|
4647 technical people. It is developed and supported by InfoDock
|
|
|
4648 Associates, a firm that offers custom support and development
|
|
|
4649 for InfoDock, XEmacs and GNU Emacs. ( @uref{http://www.infodock.com},
|
|
|
4650 @email{info@@infodock.com}, +1 408 243 3300).
|
|
|
4651
|
|
|
4652 InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
|
|
|
4653 the power of Emacs, but with an easier to use and more comprehensive
|
|
|
4654 menu-based user interface. The bottom portion of this text describes
|
|
|
4655 how it differs from XEmacs and GNU Emacs from the Free Software
|
|
|
4656 Foundation.
|
|
|
4657
|
|
|
4658 InfoDock is aimed at people who want a free, turn-key productivity
|
|
|
4659 environment. Although InfoDock is customizable, it is not intended for
|
|
|
4660 people who like basic versions of Emacs which need to be customized
|
|
|
4661 extensively for local use; standard Emacs distributions are better for
|
|
|
4662 such uses. InfoDock is for those people who want a complete,
|
|
|
4663 pre-customized environment in one package, which they need not touch
|
|
|
4664 more than once or twice a year to update to new revisions.
|
|
|
4665
|
|
|
4666 InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
|
|
|
4667 and Intel Linux systems. It is intended for use on a color display,
|
|
|
4668 although most features will work on monochrome monitors. Simply unpack
|
|
|
4669 InfoDock according to the instructions in the ID-INSTALL file and you
|
|
|
4670 are ready to run.
|
|
|
4671
|
|
|
4672 The InfoDock Manual is concise, yet sufficient as a user guide for users
|
|
|
4673 who have never used an Emacs-type editor before. For users who are
|
|
|
4674 already familiar with Emacs, it supplements the information in the GNU
|
|
|
4675 Emacs Manual.
|
|
|
4676
|
|
|
4677 InfoDock menus are much more extensive and more mature than standard
|
|
|
4678 Emacs menus. Each menu offers a @samp{Manual} item which displays
|
|
|
4679 documentation associated with the menu's functions.

|
|
|
4685 An extensive menubar providing access to global InfoDock commands.

4693
|

4694 Most modes also include mode-specific popup menus. Additionally, region and
|
|
|
4695 rectangle popup menus are included.
|
|
|
4696
|
|
|
4697 @samp{Hyperbole}, the everyday information manager, is a core part of
|
|
|
4698 InfoDock. This provides context-sensitive mouse keys, a rolodex-type
|
|
|
4699 contact manager, programmable hypertext buttons, and an autonumbered
|
|
|
4700 outliner with embedded hyperlink anchors.
|
|
|
4701
|
|
|
4702 The @samp{OO-Browser}, a multi-language object-oriented code browser, is a
|
|
|
4703 standard part of InfoDock.
|
|
|
4704
|
|
|
4705 InfoDock saves a more extensive set of user options than other Emacs
|
|
|
4706 versions.
|
|
|
4707
|
|
|
4708 InfoDock inserts a useful file header in many file types, showing the
|
|
|
4709 author, summary, and last modification time of each file. A summary
|
|
|
4710 program can then be used to summarize all of the files in a directory,
|
|
|
4711 for easy MANIFEST file creation.
|
|
|
4712
|
|
|
4713 Your working set of buffers is automatically saved and restored (if you
|
|
|
4714 answer yes to a prompt) between InfoDock sessions.
|
|
|
4715
|
|
|
4716 Refined color choices for code highlighting are provided for both dark and
|
|
|
4717 light background display frames.
|
|
|
4718
|
|
|
4719 The @kbd{C-z} key prefix performs frame-based commands which parallel the
|
|
|
4720 @kbd{C-x} key prefix for window-based commands.
|
|
|
4721
|
|
|
4722 The Smart Menu system is included for producing command menus on dumb
|
|
|
4723 terminals.
|
|
|
4724
|
|
|
4725 Lisp libraries are better categorized according to function.
|
|
|
4726
|
|
|
4727 Extensions and improvements to many areas of Emacs are included, such as:
|
|
|
4728 paragraph filling, mail reading with Rmail, shell handling, outlining, code
|
|
|
4729 highlighting and browsing, and man page browsing.
|

4806 AUC TeX is a package written by @email{abraham@@dina.kvl.dk, Per Abrahamsen}.
|
|

4807 Starting with XEmacs 19.16, AUC TeX is bundled with XEmacs. The

4811 TeX files for most variants of GNU Emacs. Many different macro packages

4812 are supported, including AMS TeX, LaTeX, and TeXinfo.

|
|
|
4882
|
|
|
4883 The reason for an Emacs package not to be included in XEmacs is
|
|
|
4884 usually one or more of the following:
|
|
|
4885
|
|
|
4886 @enumerate
|
|
|
4887 @item
|
|
|
4888 The package has not been ported to XEmacs. This will typically happen
|
|
|
4889 when it uses GNU-Emacs-specific features, which make it fail under
|
|
|
4890 XEmacs.
|
|
|
4891
|
|
|
4892 Porting a package to XEmacs can range from a trivial amount of change to
|
|
|
4893 a partial or full rewrite. Fortunately, the authors of modern packages
|
|
|
4894 usually choose to support both Emacsen themselves.
|
|
|
4895
|
|
|
4896 @item
|
|
|
4897 The package has been decided not to be appropriate for XEmacs. It may
|
|
|
4898 have an equivalent or better replacement within XEmacs, in which case
|
|
|
4899 the developers may choose not to burden themselves with supporting an
|
|
|
4900 additional package.
|
|
|
4901
|
|
|
4902 Each package bundled with XEmacs means more work for the maintainers,
|
|
|
4903 whether they want it or not. If you are ready to take over the
|
|
|
4904 maintenance responsibilities for the package you port, be sure to say
|
|
|
4905 so -- we will more likely include it.
|
|
|
4906
|
|
|
4907 @item
|
|
|
4908 The package simply hasn't been noted by the XEmacs development. If
|
|
|
4909 that's the case, the messages like yours are very useful for attracting
|
|
|
4910 our attention.
|
|
|
4911
|
|
|
4912 @item
|
|
|
4913 The package was noted by the developers, but they simply haven't yet

4914 gotten around to including/porting it. Wait for the next release or,
|
|
|
4915 even better, offer your help. It will be gladly accepted and

5003 @unnumberedsubsec Q5.0.1: How can I do source code highlighting using font-lock?
|
|
|
5004
|
|
|
5005 For most modes, font-lock is already set up and just needs to be turned
|
|
|
5006 on. This can be done by @kbd{M-x font-lock-mode}, or by having XEmacs
|
|
|
5007 automatically start it by adding lines like:
|
|
|
5008
|
|
|
5009 @lisp
|
|
|
5010 (add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock)

|
|
|
5012 @end lisp
|
|

5013
|
|
|
5014 to your @file{.emacs}. See the file @file{etc/sample.emacs} for more
|
|
|
5015 examples.
|
|

5021 @unnumberedsubsec Q5.0.2: I do not like cc-mode. How do I use the old c-mode?
|
|
|
5022
|
|
|
5023 Well, first off, consider if you really want to do this. cc-mode is
|
|
|
5024 much more powerful than the old c-mode. If you're having trouble
|
|
|
5025 getting your old offsets to work, try using @code{c-set-offset} instead.
|
|
|
5026 You might also consider using the package @code{cc-compat}.
|
|
|
5027
|
|
|
5028 But, if you still insist, add the following lines to your @file{.emacs}:
|
|
|
5029
|
|
|
5030 @lisp
|
|
|
5031 (fmakunbound 'c-mode)

|
|
|
5038 @end lisp
|
|

5039

5040 This must be done before any other reference is made to either c-mode or
|
|

5041 c++-mode.

5050 @end lisp
|
|
|
5051
|
|
|
5052 In versions of XEmacs prior to 19.14, you had to use a kludgy solution
|
|
|
5053 like this:
|
|
|
5054
|
|
|
5055 @lisp
|
|
|
5056 (setq c-font-lock-keywords c-font-lock-keywords-2

|
|
|
5059 @end lisp
|
|

5060
|
|
|
5061 It will work for C, C++ and Lisp.

5084 You can customize filling and adaptive filling with Customize.

5090 @code{text-mode-hook} by default (e.g. that's what Message does). For

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

5119 (setq initial-major-mode

5125 Note that after your init file is loaded, if
|
|
|
5126 @code{inhibit-startup-message} is @code{nil} (the default) and the
|
|
|
5127 startup buffer is @code{*scratch*} then the startup message will be
|
|
|
5128 inserted into @code{*scratch*}; it will be removed after a timeout by
|
|
|
5129 erasing the entire @code{*scratch*} buffer. Keep in mind this default
|
|
|
5130 usage of @code{*scratch*} if you desire any prior manipulation of
|
|
|
5131 @code{*scratch*} from within your Emacs init file. In particular,
|
|
|
5132 anything you insert into @code{*scratch*} from your init file will be
|
|
|
5133 later erased. Also, if you change the mode of the @code{*scratch*}
|
|
|
5134 buffer, be sure that this will not interfere with possible later
|
|
|
5135 insertion of the startup message (e.g. if you put @code{*scratch*} into
|
|
|
5136 a nonstandard mode that has automatic font lock rules, then the startup
|
|
|
5137 message might get fontified in a strange foreign manner, e.g. as code in
|
|
|
5138 some programming language).

5381 Emacs has a legacy of keyboards that produced characters with modifier
|
|
|
5382 bits, and therefore map a variety of input systems into this scheme even
|
|
|
5383 today. XEmacs is instead optimized for X events. This causes an
|
|
|
5384 incompatibility in the way key sequences are specified, but both Emacs
|
|
|
5385 and XEmacs will accept a key sequence as a vector of lists of modifiers
|
|
|
5386 that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
|
|
|
5387 @code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
|
|
|
5388 form for a single key, just (meta control a). Emacs has an abbreviated
|
|
|
5389 form for the Control and the Meta modifiers to string-characters (the
|
|
|
5390 ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
|
|
|
5391 that the abbreviated form works only for one-character key sequences,
|
|
|
5392 while Emacs users need to be aware that the string-character is rather
|
|
|
5393 limited. Specifically, the string-character can accommodate only 256
|
|
|
5394 different values, 128 of which have the Meta modifier and 128 of which
|
|
|
5395 have not. In each of these blocks, only 32 characters have the Control
|
|
|
5396 modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
|
|
|
5397 control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
|
|
|
5398 do not. Programmers are advised to use the full common form, both
|
|
|
5399 because it is more readable and less error-prone, and because it is
|
|
|
5400 supported by both Emacsen.
|
|
|
5401 @end quotation
|
|

5402
|

5403 Another (even safer) way to be sure of the key-sequences is to use the
|
|
|
5404 @code{read-kbd-macro} function, which takes a string like @samp{C-c
|
|
|
5405 <up>}, and converts it to the internal key representation of the Emacs
|
|

5406 you use. The function is available both on XEmacs and GNU Emacs.

5482 may go inside or outside of the brackets: @code{C-<down>} @equiv{}

5515 @code{\123} is a single key written in octal, and @code{< right >} is

5516 seven keys but @code{<right>} is a single function key. When in doubt,

5517 use whitespace.

|
|
5537 value, and use @code{setq} to set it later.
|
|
|
5538
|
|
|
5539 It is never a good practice to @code{setq} user variables (like
|
|
|
5540 @code{case-fold-search}, etc.), as it ignores the user's choice
|
|

5541 unconditionally. Note that @code{defvar} doesn't change the value of a

5542 variable if it was bound previously. If you wish to change a

5543 user-variable temporarily, use @code{let}:
|
|

5544
|
|

5545 @lisp

5554 @item Local variables
|

5555
|

5556 Bind them with @code{let}, which will unbind them (or restore their

|
5557 previous value, if they were bound) after exiting from the @code{let}
|
|
|
5558 form. Change the value of local variables with @code{setq} or whatever
|
|
|
5559 you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
|
|
|
5560 can even return one of its local variables.
|
|
|
5561
|
|

5562 Typical usage:
|
|
|
5563
|
|

5565 ;; iterate through the elements of the list returned by

|

5594 @unnumberedsubsec Q5.1.6: What is the typical misuse of @code{setq} ?
|
|
|
5595
|
|
|
5596 A typical misuse is probably @code{setq}ing a variable that was meant to
|
|
|
5597 be local. Such a variable will remain bound forever, never to be
|
|
|
5598 garbage-collected. For example, the code doing:
|
|
|
5599
|
|
|
5600 @lisp
|
|
|
5601 (defun my-function (whatever)
|
|
|
5602 (setq a nil)
|
|
|
5603 ... build a large list ...
|
|
|
5604 ... and exit ...)
|
|
|
5605 @end lisp
|
|
|
5606
|
|
|
5607 does a bad thing, as @code{a} will keep consuming memory, never to be
|
|
|
5608 unbound. The correct thing is to do it like this:
|
|
|
5609
|
|
|
5610 @lisp
|
|
|
5611 (defun my-function (whatever)
|
|
|
5612 (let (a) ; default initialization is to nil
|
|
|
5613 ... build a large list ...
|
|
|
5614 ... and exit, unbinding `a' in the process ...)
|
|
|
5615 @end lisp
|
|
|
5616
|
|
|
5617 Not only is this prettier syntactically, but it makes it possible for
|
|
|
5618 Emacs to garbage-collect the objects which @code{a} used to reference.
|
|
|
5619
|
|
|
5620 Note that even global variables should not be @code{setq}ed without
|
|
|
5621 @code{defvar}ing them first, because the byte-compiler issues warnings.
|

5642 Many of the advanced features of this package, such as @code{defun*},
|
|
|
5643 @code{loop}, and @code{setf}, are implemented as Lisp macros. In
|
|
|
5644 byte-compiled code, these complex notations will be expanded into
|
|
|
5645 equivalent Lisp code which is simple and efficient. For example, the
|
|
|
5646 forms
|
|
|
5647
|
|
|
5648 @lisp
|
|
|
5649 (incf i n)

5653 are expanded at compile-time to the Lisp forms
|
|
|
5654
|
|
|
5655 @lisp
|
|
|
5656 (setq i (+ i n))
|

|
|
|
5658 @end lisp
|
|
|
5659
|
|
|
5660 which are the most efficient ways of doing these respective operations
|
|
|
5661 in Lisp. Thus, there is no performance penalty for using the more
|
|
|
5662 readable @code{incf} and @code{push} forms in your compiled code.
|
|
|
5663
|
|
|
5664 @emph{Interpreted} code, on the other hand, must expand these macros
|
|
|
5665 every time they are executed. For this reason it is strongly
|
|
|
5666 recommended that code making heavy use of macros be compiled. (The
|
|
|
5667 features labelled @dfn{Special Form} instead of @dfn{Function} in this
|
|
|
5668 manual are macros.) A loop using @code{incf} a hundred times will
|
|
|
5669 execute considerably faster if compiled, and will also garbage-collect
|
|
|
5670 less because the macro expansion will not have to be generated, used,
|
|
|
5671 and thrown away a hundred times.
|
|
|
5672
|
|
|
5673 You can find out how a macro expands by using the @code{cl-prettyexpand}
|
|
|
5674 function.

5681 think well whether this is a real concern in Emacs. Much of the Emacs

5701

|
|
|
5703 the image (e.g. @code{xpm}, @code{xbm}, @code{gif}, @code{jpeg}, etc.)
|
|
|
5704 Instead of @samp{FILE}, use the image file name
|
|
|
5705 (e.g.
|

5706 @iftex

5710
|

5711 You can turn this to a function (that optionally prompts you for a file

5722 No. The documentation of @code{map-extents} states that it will iterate

|

5724 Unexperienced programmers often forget to return @code{nil} explicitly,

5725 which results in buggy code. For instance, the following code is

|
|
|
5818
|
|
|
5819 I'd like XEmacs to indent all the clauses of a Common Lisp @code{if} the
|
|
|
5820 same amount instead of indenting the 3rd clause differently from the
|
|
|
5821 first two.
|
|
|
5822
|
|
|
5823 One way is to add, to @file{.emacs}:
|
|
|
5824
|
|
|
5825 @lisp
|
|
|
5826 (put 'if 'lisp-indent-function nil)
|
|
|
5827 @end lisp
|
|
|
5828
|
|
|
5829 However, note that the package @code{cl-indent} that comes with
|
|
|
5830 XEmacs sets up this kind of indentation by default. @code{cl-indent}
|
|
|
5831 also knows about many other CL-specific forms. To use @code{cl-indent},
|
|
|
5832 one can do this:
|
|
|
5833
|
|
|
5834 @lisp
|
|
|
5835 (load "cl-indent")
|
|

5836 (setq lisp-indent-function (function common-lisp-indent-function))
|
|
|
5837 @end lisp
|
|
|
5838
|
|
|
5839 One can also customize @file{cl-indent.el} so it mimics the default
|
|
|
5840 @code{if} indentation @code{then} indented more than the @code{else}.
|
|
|
5841 Here's how:
|
|
|
5842
|
|
|
5843 @lisp
|
|
|
5844 (put 'if 'common-lisp-indent-function '(nil nil &body))

|
|

5846
|
|
|
5847 Also, a new version (1.2) of @file{cl-indent.el} was posted to
|
|
|
5848 comp.emacs.xemacs on 12/9/94. This version includes more documentation
|
|
|
5849 than previous versions. This may prove useful if you need to customize

5850 any indent-functions.

|
|
5997 Yes, abbrevs only expands word-syntax strings. While XEmacs does not
|
|
|
5998 prevent you from defining (e.g. with @kbd{C-x a g} or @kbd{C-x a l})
|
|
|
5999 abbrevs that contain special characters, it will refuse to expand
|
|
|
6000 them. So you need to ensure, that the abbreviation contains letters and
|
|
|
6001 digits only. This means that @samp{xd}, @samp{d5}, and @samp{5d} are
|
|
|
6002 valid abbrevs, but @samp{&d}, and @samp{x d} are not.
|
|
|
6003
|
|
|
6004 If this sounds confusing to you, (re-)read the online documentation for
|
|
|
6005 abbrevs (@kbd{C-h i m XEmacs @key{RET} m Abbrevs @key{RET}}), and then come back and
|
|
|
6006 read this question/answer again.
|
|
|
6007 @end quotation
|
|
|
6008

6009 Starting with XEmacs 20.3 this restriction has been lifted.

6012 @unnumberedsubsec Q5.3.10: How can I get those oh-so-neat X-Face lines?
|
|
|
6013
|
|
|
6014 Firstly there is an ftp site which describes X-faces and has the
|
|
|
6015 associated tools mentioned below, at
|
|
|
6016 @uref{ftp://ftp.cs.indiana.edu:/pub/faces/}.
|
|
|
6017
|
|
|
6018 Then the steps are
|
|
|
6019
|
|
|
6020 @enumerate
|
|
|
6021 @item
|
|
|
6022 Create 48x48x1 bitmap with your favorite tool
|
|
|
6023
|
|
|
6024 @item
|
|
|
6025 Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
|
|
|
6026 and then compile the face.
|
|
|
6027
|
|
|
6028 @item
|
|
|
6029 @example
|
|
|
6030 cat file.xbm | xbm2ikon |compface > file.face
|
|
|
6031 @end example
|
|
|
6032
|
|
|
6033 @item
|
|
|
6034 Then be sure to quote things that are necessary for emacs strings:
|
|
|
6035
|
|
|
6036 @example
|
|
|
6037 cat ./file.face | sed 's/\\/\\\\/g'
|
|
|
6038 @iftex
|
|
|
6039 \ @*
|
|
|
6040 @end iftex
|
|
|
6041 | sed 's/\"/\\\"/g' > ./file.face.quoted
|
|
|
6042 @end example
|
|
|
6043
|
|
|
6044 @item
|
|
|
6045 Then set up emacs to include the file as a mail header - there were a
|
|
|
6046 couple of suggestions here---either something like:
|
|
|
6047
|
|
|
6048 @lisp
|
|
|
6049 (setq mail-default-headers
|
|
|
6050 "X-Face: @email{Ugly looking text string here}")
|
|
|
6051 @end lisp
|
|
|
6052
|
|
|
6053 Or, alternatively, as:
|
|
|
6054
|
|
|
6055 @lisp
|
|
|
6056 (defun mail-insert-x-face ()
|
|
|
6057 (save-excursion
|
|
|
6058 (goto-char (point-min))
|
|
|
6059 (search-forward mail-header-separator)
|
|
|
6060 (beginning-of-line)
|
|
|
6061 (insert "X-Face:")
|
|
|
6062 (insert-file-contents "~/.face")))
|
|
|
6063
|
|
|
6064 (add-hook 'mail-setup-hook 'mail-insert-x-face)
|
|
|
6065 @end lisp
|
|
|
6066 @end enumerate
|
|
|
6067
|
|
|
6068 However, 2 things might be wrong:
|
|
|
6069
|
|
|
6070 Some versions of pbmtoicon produces some header lines that is not
|
|
|
6071 expected by the version of compface that I grabbed. So I found I had to
|
|
|
6072 include a @code{tail +3} in the pipeline like this:
|
|
|
6073
|
|
|
6074 @example
|
|
|
6075 cat file.xbm | xbm2ikon | tail +3 |compface > file.face
|
|
|
6076 @end example
|
|
|
6077
|
|
|
6078 Some people have also found that if one uses the @code{(insert-file)}
|
|
|
6079 method, one should NOT quote the face string using the sed script .
|
|
|
6080
|
|
|
6081 It might also be helpful to use @email{stig@@hackvan.com, Stig's} script
|
|
|
6082 (included in the compface distribution at XEmacs.org) to do the
|
|
|
6083 conversion. For convenience xbm2xface is available for anonymous FTP at
|
|
|
6084 @uref{ftp://ftp.miranova.com/pub/xemacs/xbm2xface.pl}.

6111 Emacs Info and XEmacs Info do many things differently. If you're trying to

6116 Emacs Info scans @code{Info-directory-list} from right-to-left while
|
|
|
6117 XEmacs Info reads it from left-to-right, so append to the @emph{correct}
|
|
|
6118 end of the list.
|
|
|
6119
|
|
|
6120 @item
|
|

6121 Use @code{Info-default-directory-list} to initialize
|
|
|
6122 @code{Info-directory-list} @emph{if} it is available at startup, but not
|
|
|
6123 all Emacsen define it.
|
|
|
6124
|
|
|
6125 @item
|
|
|
6126 Emacs Info looks for a standard @file{dir} file in each of the
|
|
|
6127 directories scanned from #1 and magically concatenates them together.
|
|
|
6128
|
|
|
6129 @item
|
|
|
6130 XEmacs Info looks for a @file{localdir} file (which consists of just the
|
|
|
6131 menu entries from a @file{dir} file) in each of the directories scanned
|
|
|
6132 from #1 (except the first), does a simple concatenation of them, and
|
|
|
6133 magically attaches the resulting list to the end of the menu in the
|
|
|
6134 @file{dir} file in the first directory.
|
|
|
6135 @end enumerate
|
|
|
6136
|
|
|
6137 Another alternative is to convert the documentation to HTML with
|
|
|
6138 texi2html and read it from a web browser like Lynx or W3.

6142 @unnumberedsubsec Q5.3.12: What do I need to change to make printing work?
|
|
|
6143
|
|
|
6144 For regular printing there are two variables that can be customized.
|
|
|
6145
|
|
|
6146 @table @code
|
|
|
6147 @item lpr-command
|
|
|
6148 This should be set to a command that takes standard input and sends
|
|
|
6149 it to a printer. Something like:
|
|
|
6150
|
|
|
6151 @lisp
|
|
|
6152 (setq lpr-command "lp")
|
|
|
6153 @end lisp
|
|
|
6154
|
|
|
6155 @item lpr-switches
|
|
|
6156 This should be set to a list that contains whatever the print command
|
|
|
6157 requires to do its job. Something like:
|
|
|
6158
|
|
|
6159 @lisp
|
|
|
6160 (setq lpr-switches '("-depson"))
|
|
|
6161 @end lisp
|
|
|
6162 @end table
|
|
|
6163
|
|
|
6164 For postscript printing there are three analogous variables to
|
|
|
6165 customize.
|
|
|
6166
|
|
|
6167 @table @code
|
|
|
6168 @item ps-lpr-command
|
|
|
6169 This should be set to a command that takes postscript on standard input
|
|
|
6170 and directs it to a postscript printer.
|
|
|
6171
|
|
|
6172 @item ps-lpr-switches
|
|
|
6173 This should be set to a list of switches required for
|
|
|
6174 @code{ps-lpr-command} to do its job.
|
|
|
6175
|
|
|
6176 @item ps-print-color-p
|
|
|
6177 This boolean variable should be set @code{t} if printing will be done in
|
|
|
6178 color, otherwise it should be set to @code{nil}.
|
|
|
6179 @end table
|
|
|
6180
|
|
|
6181 NOTE: It is an undocumented limitation in XEmacs that postscript
|
|
|
6182 printing (the @code{Pretty Print Buffer} menu item) @strong{requires} a
|
|
|
6183 window system environment. It cannot be used outside of X11.

6204
|
|
|
6205 The biggest changes in 20.2 include integration of EFS (the next
|
|
|
6206 generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
|
|
|
6207 major mode for editing Tex and LaTeX, and a lot of other stuff). Many
|
|
|
6208 bugs from 20.0 have been fixed for this release. 20.2 also contains a
|
|
|
6209 new system for customizing XEmacs options, invoked via @kbd{M-x
|
|
|
6210 customize}.
|
|
|
6211
|
|
|
6212 XEmacs 20.2 is the development release (20.0 was beta), and is no longer
|
|
|
6213 considered unstable.

|
|
|
6217
|
|
|
6218 XEmacs 20.3 was released in November 1997. It contains many bugfixes,
|
|
|
6219 and a number of new features, including Autoconf 2 based configuration,
|
|
|
6220 additional support for Mule (Multi-language extensions to Emacs), many
|
|
|
6221 more customizations, multiple frames on TTY-s, support for multiple info
|
|
|
6222 directories, an enhanced gnuclient, improvements to regexp matching,
|
|
|
6223 increased MIME support, and many, many synches with GNU Emacs 20.
|
|
|
6224
|
|
|
6225 The XEmacs/Mule support has been only seriously tested in a Japanese
|
|
|
6226 locale, and no doubt many problems still remain. The support for
|
|
|
6227 ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
|
|
|
6228 price -- about a 30% slowdown from 19.16. We're making progress on
|
|
|
6229 improving performance and XEmacs 20.3 compiled without Mule (which is
|
|
|
6230 the default) is definitely faster than XEmacs 19.16.
|
|
|
6231
|
|
|
6232 XEmacs 20.3 is the first non-beta v20 release, and will be the
|
|
|
6233 basis for all further development.
