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. | |
398 | |
399 The previous maintainer of the FAQ was @email{rossini@@stat.sc.edu, | |
400 Anthony Rossini}, who started it, after getting tired of hearing JWZ | |
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 | |
406 contributors to this FAQ are listed later in this document. | |
407 | |
408 The previous version was converted to hypertext format, and edited by | |

469 | |
470 | |
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. | |

480 XEmacs 20.4 is a minor upgrade from 20.3, containing many bugfixes. It | |
481 was released in February 1998. | |
482 | |
483 XEmacs 19.16 was the last release of v19, released in November, 1997, | |
484 which was also the last version without international language support. | |

569 | |
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 | |

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

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 | |
644 @email{xemacs-nt@@xemacs.org}. | |

654 full-time, senior-level staff working under a professionally managed | |

895 @unnumberedsec 1.3: Internationalization | |
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. | |

967 @unnumberedsubsec Q1.3.2: What is the status of Asian-language support, aka MULE? | |
968 | |
969 The MULE support works OK but still needs a fair amount of work before | |
970 it's really solid. We could definitely use some help here, esp. people | |
971 who speak Japanese and will use XEmacs/MULE to work with Japanese and | |
972 have some experience with E-Lisp. | |

987 | |
988 The message-catalog support has mostly been written but doesn't | |
989 currently work. The first release of XEmacs 20 will @emph{not} support | |
990 it. However, menubar localization @emph{does} work, even in 19.14. To | |
991 enable it, add to your @file{Emacs} file entries like this: | |
992 | |
993 @example | |
994 Emacs*XlwMenu.resourceLabels: True | |
995 Emacs*XlwMenu.file.labelString: Fichier | |

1007 @quotation | |
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 | |
1028 Solaris. (XEmacs 20 will support XIM input). | |
1029 | |
1030 Egg consists of following parts: | |
1031 | |
1032 @enumerate | |
1033 @item | |
1034 Input character Translation System (ITS) layer. | |
1035 It translates ASCII inputs to Kana/PinYin/Hangul characters. | |
1036 | |
1037 @item | |
1038 Kana/PinYin/Hangul to Kanji transfer layer. | |
1039 It is interface layer for network Kana-Kanji server (Wnn and Sj3). | |
1040 @end enumerate | |
1041 | |
1042 These input methods are modal, namely there are mode, alphabet mode and | |
1043 Kana-Kanji transfer mode. However there are mode-less input methods for | |
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, | |
1046 @code{(canna-boil)}, and there are some boiled-egg like utilities. In | |
1047 addition, it was planned to make an abstraction for all transfer type | |
1048 input methods. However authors of input methods are busy, so maybe this | |
1049 plan is stopped. Perhaps after Mule merged GNU Emacs will be released, | |
1050 it will be continued. | |

1059 MULE and XEmacs are quite different. So the application | |
1060 implementor must write separate code for these mule variants. | |
1061 | |
1062 MULE and the next version of Emacs are similar but the symbols are very | |
1063 different---requiring separate code as well. | |
1064 | |
1065 Namely we must support 3 kinds of mule variants and 4 or 5 or 6 kinds of | |
1066 emacs variants... (;_;) I'm shocked, so I wrote a wrapper package called | |
1067 @code{emu} to provide a common interface. | |

1184 @unnumberedsubsec Q1.4.4: May I see an example of a useful XEmacs Lisp function? | |
1185 | |
1186 The following function does a little bit of everything useful. It does | |
1187 something with the prefix argument, it examines the text around the | |
1188 cursor, and it's interactive so it may be bound to a key. It inserts | |
1189 copies of the current word the cursor is sitting on at the cursor. If | |
1190 you give it a prefix argument: @kbd{C-u 3 M-x double-word} then it will | |
1191 insert 3 copies. | |
1192 | |
1193 @lisp | |
1194 (defun double-word (count) | |
1195 "Insert a copy of the current word underneath the cursor" | |
1196 (interactive "*p") | |
1197 (let (here there string) | |
1198 (save-excursion | |
1199 (forward-word -1) | |
1200 (setq here (point)) | |
1201 (forward-word 1) | |
1202 (setq there (point)) | |

1205 (insert string) | |
1206 (decf count)))) | |
1207 @end lisp | |
1208 | |
1209 The best way to see what is going on here is to let XEmacs tell you. | |
1210 Put the code into an XEmacs buffer, and do a @kbd{C-h f} with the cursor | |
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}. | |

1230 @unnumberedsubsec Q1.4.6: What's the difference between a macro and a function? | |
1231 | |
1232 Quoting from the Lisp Reference (a.k.a @dfn{Lispref}) Manual: | |
1233 | |
1234 @dfn{Macros} enable you to define new control constructs and other | |
1235 language features. A macro is defined much like a function, but instead | |
1236 of telling how to compute a value, it tells how to compute another Lisp | |
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 | |

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. | |
1349 | |

1353 Although this entry has been written for XEmacs 19.13, most of it still | |
1354 stands true. | |

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 | |
1475 @example | |
1476 20778 /usr/local/lib/xemacs-19.13 | |
1477 @end example | |
1478 | |
1479 The 20MB achieved is less than half of what the full distribution takes up, | |
1480 @strong{and} can be achieved without deleting a single file. | |
1481 @end quotation | |
1482 | |
1483 @email{boffi@@hp735.stru.polimi.it, Giacomo Boffi} provides this procedure: | |
1484 | |
1485 @quotation | |
1486 Substitute @file{/usr/local/lib/} with the path where the xemacs tree is | |
1487 rooted, then use this script: | |
1488 | |
1489 @example | |
1490 #!/bin/sh | |
1491 | |
1492 r=/usr/local/lib/xemacs-19.13/lisp | |
1493 | |
1494 cd $r ; rm -f cmpr ; touch cmpr | |
1495 | |
1496 du -s . | |
1497 | |
1498 for d in * ; do | |
1499 if test -d $d ; then | |
1500 cd $d | |
1501 for f in *.el ; do | |
1502 # compress (remove) only (ONLY) the sources that have a | |
1503 # corresponding compiled file --- do not (DO NOT) | |
1504 # touch other sources | |
1505 if test -f $@{f@}c ; then gzip -v9 $f >> $r/cmpr ; fi | |
1506 done | |
1507 cd .. | |
1508 fi | |
1509 done | |
1510 | |
1511 du -s . | |
1512 @end example | |
1513 | |
1514 A step beyond would be substituting @samp{rm -f} for @samp{gzip -v9}, | |
1515 but you have to be desperate for removing the sources (remember that | |
1516 emacs can access compressed files transparently). | |
1517 | |
1518 Also, a good megabyte could easily be trimmed from the $r/../etc | |
1519 directory, e.g., the termcap files, some O+NEWS, others that I don't | |
1520 remember as well. | |

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 | |
1555 @uref{ftp://ftp.x.org/contrib/audio/nas/}. | |

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 | |
1742 SunOS 4.x systems don't have DNS-based name lookups in libc. | |
1743 | |
1744 This is also why Netscape ships two binaries for SunOS 4.1.x. | |
1745 | |
1746 The best solution is to compile it yourself; the configure script will | |
1747 check to see if you've put DNS in the shared libc and will then proceed | |
1748 to link against the DNS resolver library code. | |

1755 | |
1756 @quotation | |
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. | |

1962 set the environment variable @var{XKEYSYMDB} to the location of the | |

1974 is the stock R6 version and is backwards compatible) or set your | |

2074 following resources: | |
2075 | |
2076 @example | |
2077 xemacs*cursorColor: black | |
2078 xemacs*pointerColor: black | |
2079 @end example | |
2080 | |
2081 With the new colors installed the problem still occurs if the above | |
2082 resources are not defined. | |
2083 | |
2084 If the new colors are not present then an additional error occurs on | |
2085 XEmacs startup, which says @samp{Color Red3} not defined. | |

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. | |
2330 | |
2331 @email{1CMC3466@@ibm.mtsac.edu, Curtiss} suggests upgrading to ld.so version 1.8 | |
2332 if dynamic linking and debugging is a problem on Linux. | |
2333 | |
2334 @item | |
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: | |
2338 | |
2339 @enumerate a | |
2340 @item | |
2341 Your executable has been stripped. Bad news. Tell your sysadmin not to | |
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. | |
2360 | |
2361 @item | |
2362 If you compiled 19.14 with @samp{--debug} (or by default in later | |
2363 versions), you will get a Lisp backtrace output when XEmacs crashes, so | |
2364 you'll have something useful. | |
2365 | |
2366 @end enumerate | |
2367 | |
2368 @item | |
2369 If you compile with the newer gcc variants gcc-2.8 or egcs, you will | |
2370 also need gdb 4.17. Earlier releases of gdb can't handle the debug | |
2371 information generated by the newer compilers. | |
2372 | |
2373 @item | |
2374 The above information on using @file{src/gdbinit} works for XEmacs-21.0 | |
2375 and above. For older versions of XEmacs, there are different | |
2376 @file{gdbinit} files provided in the @file{src} directory. Use the one | |
2377 corresponding to the configure options used when building XEmacs. | |

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

2431 I've just discovered that my hpux 10.01 binary was working less well | |
2432 than expected. In fact, on a 10.10 system, @code{(while t)} was not | |

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 | |

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. | |

2659 @unnumberedsubsec Q3.0.1: What version of Emacs am I running? | |
2660 | |
2661 How can @file{.emacs} determine which of the family of Emacsen I am | |
2662 using? | |
2663 | |
2664 To determine if you are currently running GNU Emacs 18, GNU Emacs 19, | |
2665 XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the | |
2666 example given in @file{etc/sample.emacs}. There are other nifty things | |
2667 in there as well! | |
2668 | |
2669 For all new code, all you really need to do is: | |
2670 | |
2671 @lisp | |

2677 | |
2678 I know I can evaluate Elisp expressions from @code{*scratch*} buffer | |
2679 with @kbd{C-j} after the expression. How do I do it from another | |
2680 buffer? | |
2681 | |
2682 Press @kbd{M-:} (the default binding of @code{eval-expression}), and | |
2683 enter the expression to the minibuffer. In XEmacs prior to 19.15 | |
2684 @code{eval-expression} used to be a disabled command by default. If | |
2685 this is the case, upgrade your XEmacs. | |

2691 not work! Is there a reason for this? If you do it at the EVAL prompt | |
2692 it works fine!! How strange. | |
2693 | |
2694 Use @code{setq-default} instead, since @code{tab-width} is | |

2701 front of the load-path, the other at the end: | |
2702 | |
2703 @lisp | |
2704 ;;; Add things at the beginning of the load-path, do not add | |
2705 ;;; duplicate directories: | |
2706 (pushnew "bar" load-path :test 'equal) | |
2707 | |
2708 (pushnew "foo" load-path :test 'equal) | |
2709 | |

2728 Use the following elisp: | |
2729 | |
2730 @lisp | |
2731 (fboundp 'foo) | |
2732 @end lisp | |
2733 | |
2734 It's almost always a mistake to test @code{emacs-version} or any similar | |
2735 variables. | |
2736 | |
2737 Instead, use feature-tests, such as @code{featurep}, @code{boundp}, | |
2738 @code{fboundp}, or even simple behaviroal tests, eg.: | |
2739 | |
2740 @lisp | |
2741 (defvar foo-old-losing-code-p | |
2742 (condition-case nil (progn (losing-code t) nil) | |
2743 (wrong-number-of-arguments t))) | |
2744 @end lisp | |
2745 | |
2746 There is an incredible amount of broken code out there which could work | |
2747 much better more often in more places if it did the above instead of | |
2748 trying to divine its environment from the value of one variable. | |

2753 It would be good having it in a buffer, as the output of | |
2754 @code{(face-list)} is too wide to fit to a minibuffer. | |
2755 | |
2756 Evaluate the expression in the @samp{*scratch*} buffer with point after | |
2757 the rightmost paren and typing @kbd{C-j}. | |
2758 | |
2759 If the minibuffer smallness is the only problem you encounter, you can | |

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: | |

3024 Note that you should use @samp{Emacs.} and not @samp{Emacs*} when | |

3035 This is confusing because modeline is a face, and can be found listed | |

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. | |

3101 There are several ways to do it. For example, you could specify a | |

3110 and then reload ~/.Xresources and restart XEmacs. Alternatively, | |
3111 since each face can have its own pixmap background, a better way | |

3228 Notes: | |
3229 | |
3230 @itemize @bullet | |

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})}, | |

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}). | |

3354 I cannot manage to globally bind my @kbd{Delete} key to something other | |
3355 than the default. How does one do this? | |
3356 | |
3357 @lisp | |

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. | |

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 | |

3803 | |
3804 I am trying to use a resource like @code{Emacs*menubar*font} to set the | |
3805 font of the menubar but it's not working. | |
3806 | |
3807 If you are using the real Motif menubar, this resource is not | |
3808 recognized; you have to say: | |
3809 | |
3810 @example | |
3811 Emacs*menubar*fontList: FONT | |
3812 @end example | |
3813 | |
3814 If you are using the Lucid menubar, the former resource will be | |
3815 recognized only if the latter resource is unset. This means that the | |
3816 resource | |
3817 | |
3818 @example | |
3819 *fontList: FONT | |
3820 @end example | |
3821 | |

3824 @example | |

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 | |

3852 @unnumberedsec 3.9: Scrollbars | |
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)) | |

3888 | |
3889 Here's a recap of how to use resources to change your scrollbar colors: | |
3890 | |
3891 @example | |
3892 ! Motif scrollbars | |
3893 | |
3894 Emacs*XmScrollBar.Background: skyblue | |
3895 Emacs*XmScrollBar.troughColor: lightgray | |
3896 | |
3897 ! Athena scrollbars | |
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. | |

3906 @unnumberedsubsec Q3.9.3: Moving the scrollbar can move the point; can I disable this? | |
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. | |

3920 @unnumberedsubsec Q3.9.4: How can I get automatic horizontal scrolling? | |
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. | |

3948 @unnumberedsec 3.10: Text Selections | |
3949 @unnumberedsubsec Q3.10.1: How can I turn off or change highlighted selections? | |
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 | |
3957 (setq zmacs-regions nil) | |
3958 @end lisp | |
3959 | |
3960 Starting with XEmacs-20.2 you can also change this with Customize. Select | |
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}}. | |

3964 To change the face for selection, look at @code{Options->Customize} on | |
3965 the menubar. | |

3968 @unnumberedsubsec Q3.10.2: How do I get that typing on an active region removes it? | |
3969 | |
3970 I want to change things so that if I select some text and start typing, | |
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. | |
3977 | |
3978 To get this behavior, add the following line to your @file{.emacs}: | |
3979 | |
3980 @lisp | |
3981 (turn-on-pending-delete) | |

3999 @kbd{M-x customize-variable @key{RET} isearch-highlight @key{RET}}. | |
4000 | |
4001 Note also that isearch-highlight affects query-replace and ispell. | |
4002 Instead of disabling isearch-highlight you may find that a better | |
4003 solution consists of customizing the @code{isearch} face. | |

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. | |

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. | |
4680 | |
4681 @noindent | |
4682 Four types of menubars are provided: | |
4683 @enumerate | |
4684 @item | |
4685 An extensive menubar providing access to global InfoDock commands. | |
4686 @item | |
4687 Mode-specific menubars tailored to the current major mode. | |
4688 @item | |
4689 A simple menubar for basic editing to help novices get started with InfoDock. | |
4690 @item | |
4691 The standard XEmacs menubar. | |
4692 @end enumerate | |
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. | |
4730 | |

4739 | |
4740 InfoDock is available across the Internet via anonymous FTP. To get | |
4741 it, first move to a directory into which you want the InfoDock archive | |
4742 files placed. We will call this <DIST-DIR>. | |
4743 | |
4744 @example | |
4745 cd <DIST-DIR> | |
4746 @end example | |
4747 | |
4748 Ftp to ftp.xemacs.org (Internet Host ID = 128.174.252.16): | |
4749 | |
4750 @example | |
4751 prompt> ftp ftp.xemacs.org | |
4752 @end example | |
4753 | |
4754 Login as @samp{anonymous} with your own <user-id>@@<site-name> as a password. | |
4755 | |
4756 @example | |
4757 Name (ftp.xemacs.org): anonymous | |
4758 331 Guest login ok, send your complete e-mail address as password. | |
4759 Password: -<your-user-id>@@<your-domain> | |
4760 230 Guest login ok, access restrictions apply. | |
4761 @end example | |
4762 | |
4763 Move to the location of the InfoDock archives: | |
4764 | |
4765 @example | |
4766 ftp> cd pub/infodock | |
4767 @end example | |
4768 | |
4769 Set your transfer mode to binary: | |
4770 | |
4771 @example | |
4772 ftp> bin | |
4773 200 Type set to I. | |
4774 @end example | |
4775 | |
4776 Turn off prompting: | |
4777 | |
4778 @example | |
4779 ftp> prompt | |
4780 Interactive mode off. | |
4781 @end example | |
4782 | |
4783 Retrieve the InfoDock archives that you want, either by using a | |
4784 @samp{get <file>} for each file you want or by using the following to | |
4785 get a complete distribution, including all binaries: | |
4786 | |
4787 @example | |
4788 ftp> mget ID-INSTALL | |
4789 ftp> mget id-* | |
4790 @end example | |
4791 | |
4792 Close the FTP connection: | |
4793 | |
4794 @example | |
4795 ftp> quit | |
4796 221 Goodbye. | |
4797 @end example | |
4798 | |

4805 | |
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 | |
4808 following information is from the @file{README} and website. | |
4809 | |
4810 AUC TeX is an extensible package that supports writing and formatting | |
4811 TeX files for most variants of GNU Emacs. Many different macro packages | |
4812 are supported, including AMS TeX, LaTeX, and TeXinfo. | |

4857 AUC TeX works fine on both stock Emacs and XEmacs has been doing so for | |
4858 a very very long time. This is mostly due to the work of | |
4859 @email{abraham@@dina.kvl.dk, Per Abrahamsen} (clap clap) in particular his @file{easymenu} | |
4860 package. Which leads to what is probably the problem... | |

4867 The TeX-lisp-directory in @file{tex-site.el} and the makefile don't | |

4870 Fix: make sure you configure AUC TeX properly @strong{before} installing. | |

4872 @item | |
4873 You have an old version of easymenu.el in your path. | |

4881 @unnumberedsubsec Q4.7.5: Is there a reason for an Emacs package not to be included in XEmacs? | |
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 | |
4916 appreciated. | |

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) | |
5011 (add-hook 'dired-mode-hook 'turn-on-font-lock) | |

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) | |
5032 (makunbound 'c-mode-map) | |

5037 (load-library "old-c++-mode") | |
5038 @end lisp | |

5047 | |
5048 @lisp | |
5049 (setq-default font-lock-maximum-decoration t) | |
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 | |
5057 c++-font-lock-keywords c++-font-lock-keywords-2 | |
5058 lisp-font-lock-keywords lisp-font-lock-keywords-2) | |
5059 @end lisp | |
5060 | |
5061 It will work for C, C++ and Lisp. | |

5070 | |
5071 @lisp | |
5072 (setq indent-line-function 'indent-relative-maybe) | |
5073 @end lisp | |
5074 | |
5075 If you want to get fancy, try the @code{filladapt} package available | |
5076 standard with XEmacs. Put this into your @file{.emacs}: | |
5077 | |
5078 @lisp | |
5079 (require 'filladapt) | |
5080 (add-hook 'text-mode-hook 'turn-on-filladapt-mode) | |
5081 ;;; and others ... | |
5082 @end lisp | |
5083 | |
5084 You can customize filling and adaptive filling with Customize. | |
5085 Select from the @code{Options} menu | |
5086 @code{Customize->Emacs->->Editing->Fill->Fill...} | |
5087 or type @kbd{M-x customize @key{RET} fill @key{RET}}. | |
5088 | |
5089 Note that well-behaving text-lookalike modes will run | |

5096 @unnumberedsubsec Q5.0.5: How can I get XEmacs to come up in text/auto-fill mode by default? | |
5097 | |
5098 Try the following lisp in your @file{.emacs}: | |
5099 | |
5100 @lisp | |
5101 (setq default-major-mode 'text-mode) | |
5102 (setq text-mode-hook 'turn-on-auto-fill) | |
5103 @end lisp | |
5104 | |
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 | |
5120 (lambda () | |
5121 (text-mode) | |
5122 (turn-on-auto-fill))) | |
5123 @end lisp | |
5124 | |
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). | |

5378 @email{clerik@@naggum.no, Erik Naggum} writes; | |
5379 | |
5380 @quotation | |
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. | |

5432 The @code{read-kbd-macro} function returns the internal Emacs | |
5433 representation of a human-readable string (which is its argument). | |
5434 Thus: | |
5435 | |
5436 @lisp | |
5437 (read-kbd-macro "C-c C-a") | |
5438 @result{} [(control ?c) (control ?a)] | |
5439 | |

5441 @result{} [(control ?c) (control ?.) up] | |

5445 understands internally---the sequences @code{"\C-x\C-c"} and @code{[3 | |
5446 67108910 up]}, respectively. | |
5447 | |
5448 The exact @dfn{human-readable} syntax is defined in the docstring of | |
5449 @code{edmacro-mode}. I'll repeat it here, for completeness. | |
5450 | |
5451 @quotation | |
5452 Format of keyboard macros during editing: | |
5453 | |
5454 Text is divided into @dfn{words} separated by whitespace. Except for | |
5455 the words described below, the characters of each word go directly as | |
5456 characters of the macro. The whitespace that separates words is | |
5457 ignored. Whitespace in the macro must be written explicitly, as in | |
5458 @kbd{foo @key{SPC} bar @key{RET}}. | |
5459 | |
5460 @itemize @bullet | |
5461 @item | |
5462 The special words @kbd{RET}, @kbd{SPC}, @kbd{TAB}, @kbd{DEL}, @kbd{LFD}, | |
5463 @kbd{ESC}, and @kbd{NUL} represent special control characters. The | |
5464 words must be written in uppercase. | |
5465 | |
5466 @item | |
5467 A word in angle brackets, e.g., @code{<return>}, @code{<down>}, or | |
5468 @code{<f1>}, represents a function key. (Note that in the standard | |
5469 configuration, the function key @code{<return>} and the control key | |
5470 @key{RET} are synonymous.) You can use angle brackets on the words | |
5471 @key{RET}, @key{SPC}, etc., but they are not required there. | |
5472 | |
5473 @item | |
5474 Keys can be written by their @sc{ascii} code, using a backslash followed | |
5475 by up to six octal digits. This is the only way to represent keys with | |
5476 codes above \377. | |
5477 | |
5478 @item | |
5479 One or more prefixes @kbd{M-} (meta), @kbd{C-} (control), @kbd{S-} | |
5480 (shift), @kbd{A-} (alt), @kbd{H-} (hyper), and @kbd{s-} (super) may | |
5481 precede a character or key notation. For function keys, the prefixes | |
5482 may go inside or outside of the brackets: @code{C-<down>} @equiv{} | |
5483 @code{<C-down>}. The prefixes may be written in any order: @kbd{M-C-x} | |
5484 @equiv{} @kbd{C-M-x}. | |
5485 | |
5486 Prefixes are not allowed on multi-key words, e.g., @kbd{C-abc}, except | |
5487 that the Meta prefix is allowed on a sequence of digits and optional | |
5488 minus sign: @kbd{M--123} @equiv{} @kbd{M-- M-1 M-2 M-3}. | |
5489 | |
5490 @item | |
5491 The @code{^} notation for control characters also works: @kbd{^M} | |
5492 @equiv{} @kbd{C-m}. | |
5493 | |
5494 @item | |
5495 Double angle brackets enclose command names: @code{<<next-line>>} is | |
5496 shorthand for @kbd{M-x next-line @key{RET}}. | |
5497 | |
5498 @item | |
5499 Finally, @code{REM} or @code{;;} causes the rest of the line to be | |
5500 ignored as a comment. | |
5501 @end itemize | |

5522 | |
5523 In most cases, not noticeable. Besides, there's no avoiding | |
5524 @code{let}---you have to bind your local variables, after all. Some | |
5525 pose a question whether to nest @code{let}s, or use one @code{let} per | |
5526 function. I think because of clarity and maintenance (and possible | |
5527 future implementation), @code{let}-s should be used (nested) in a way to | |
5528 provide the clearest code. | |

5531 @unnumberedsubsec Q5.1.5: What is the recommended use of @code{setq}? | |
5532 | |
5533 @itemize @bullet | |
5534 @item Global variables | |
5535 | |
5536 You will typically @code{defvar} your global variable to a default | |
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 | |
5546 (let ((case-fold-search nil)) | |
5547 ... ; code with searches that must be case-sensitive | |
5548 ...) | |
5549 @end lisp | |
5550 | |
5551 You will notice the user-variables by their docstrings beginning with an | |
5552 asterisk (a convention). | |
5553 | |
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 | |
5564 @lisp | |
5565 ;; iterate through the elements of the list returned by | |
5566 ;; `hairy-function-that-returns-list' | |
5567 (let ((l (hairy-function-that-returns-list))) | |
5568 (while l | |
5569 ... do something with (car l) ... | |
5570 (setq l (cdr l)))) | |
5571 @end lisp | |
5572 | |
5573 Another typical usage includes building a value simply to work with it. | |
5574 | |
5575 @lisp | |
5576 ;; Build the mode keymap out of the key-translation-alist | |
5577 (let ((inbox (file-truename (expand-file-name box))) | |
5578 (i 0)) | |
5579 ... code dealing with inbox ... | |
5580 inbox) | |
5581 @end lisp | |
5582 | |
5583 This piece of code uses the local variable @code{inbox}, which becomes | |
5584 unbound (or regains old value) after exiting the form. The form also | |
5585 returns the value of @code{inbox}, which can be reused, for instance: | |
5586 | |
5587 @lisp | |
5588 (setq foo-processed-inbox | |
5589 (let .....)) | |

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. | |
5622 The reason for the warning is the following: | |
5623 | |
5624 @lisp | |
5625 (defun flurgoze nil) ; ok, global internal variable | |
5626 ... | |
5627 | |
5628 (setq flurghoze t) ; ops! a typo, but semantically correct. | |
5629 ; however, the byte-compiler warns. | |

5637 | |
5638 It shouldn't. Here is what Dave Gillespie has to say about cl.el | |
5639 performance: | |
5640 | |
5641 @quotation | |
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) | |
5650 (push x (car p)) | |
5651 @end lisp | |
5652 | |
5653 are expanded at compile-time to the Lisp forms | |
5654 | |
5655 @lisp | |
5656 (setq i (+ i n)) | |
5657 (setcar p (cons x (car p))) | |
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. | |

5680 Yes. Emacs byte-compiler cannot do much to optimize recursion. But | |

5694 @lisp | |
5695 (make-annotation (make-glyph '([FORMAT :file FILE] | |

5718 I tried to use @code{map-extents} to do an operation on all the extents | |
5719 in a region. However, it seems to quit after processing a random number | |
5720 of extents. Is it buggy? | |
5721 | |
5722 No. The documentation of @code{map-extents} states that it will iterate | |
5723 across the extents as long as @var{function} returns @code{nil}. | |
5724 Unexperienced programmers often forget to return @code{nil} explicitly, | |
5725 which results in buggy code. For instance, the following code is | |

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. | |

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)) | |

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 | |
6112 support a number of versions of Emacs, here are some notes to remember: | |
6113 | |
6114 @enumerate | |
6115 @item | |
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. | |

6216 @unnumberedsubsec Q6.0.2: What is new in 20.3? | |
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. | |
