612 This manual documents the use and simple customization of the XEmacs
613 editor. The reader is not expected to be a programmer to use this
614 editor, and simple customizations do not require programming skills either.
615 Users who are not interested in customizing XEmacs can ignore the scattered
618 This document is primarily a reference manual, but it can also be used as a
619 primer. However, if you are new to XEmacs, consider using the on-line,
620 learn-by-doing tutorial, which you get by running XEmacs and typing
621 @kbd{C-h t}. With it, you learn XEmacs by using XEmacs on a specially
622 designed file which describes commands, tells you when to try them,
623 and then explains the results you see. Using the tutorial gives a more vivid
624 introduction than the printed manual. Also consider reading the XEmacs
625 New User's Guide, which is intended specifically as an introductory
626 manual rather than as a reference guide.
628 On first reading, just skim chapters one and two, which describe the
629 notational conventions of the manual and the general appearance of the
630 XEmacs display frame. Note which questions are answered in these chapters,
631 so you can refer back later. After reading chapter four you should
632 practice the commands there. The next few chapters describe fundamental
633 techniques and concepts that are used constantly. You need to understand
634 them thoroughly, experimenting with them if necessary.
636 To find the documentation on a particular command, look in the index.
637 Keys (character commands) and command names have separate indexes. There
638 is also a glossary, with a cross reference for each term.
641 If you know vaguely what the command
642 does, look in the command summary. The command summary contains a line or
643 two about each command, and a cross reference to the section of the
644 manual that describes the command in more detail; related commands
645 are grouped together.
648 This manual comes in two forms: the published form and the Info form.
649 The Info form is for on-line perusal with the INFO program; it is
650 distributed along with XEmacs. Both forms contain substantially the
651 same text and are generated from a common source file, which is also
652 distributed along with XEmacs.
654 XEmacs is a member of the Emacs editor family. There are many Emacs
655 editors, all sharing common principles of organization. For information on
656 the underlying philosophy of Emacs and the lessons learned from its
657 development, write for a copy of AI memo 519a, ``Emacs, the Extensible,
658 Customizable Self-Documenting Display Editor'', to Publications Department,
659 Artificial Intelligence Lab, 545 Tech Square, Cambridge, MA 02139, USA. At
660 last report they charge $2.25 per copy. Another useful publication is LCS
661 TM-165, ``A Cookbook for an Emacs'', by Craig Finseth, available from
662 Publications Department, Laboratory for Computer Science, 545 Tech Square,
663 Cambridge, MA 02139, USA. The price today is $3.
665 This manual is for XEmacs installed on UNIX systems. XEmacs also
666 exists on Microsoft Windows and Windows NT as Win-Emacs (which is
667 actually based on Lucid Emacs 19.6, an older incarnation of XEmacs).

693 You can use it for your programs, too.
695 When we speak of free software, we are referring to freedom, not
696 price. Specifically, the General Public License is designed to make
697 sure that you have the freedom to give away or sell copies of free
698 software, that you receive source code or can get it if you want it,
699 that you can change the software or use pieces of it in new free
700 programs; and that you know you can do these things.
702 To protect your rights, we need to make restrictions that forbid
703 anyone to deny you these rights or to ask you to surrender the rights.
704 These restrictions translate to certain responsibilities for you if you
705 distribute copies of the software, or if you modify it.
707 For example, if you distribute copies of a such a program, whether
708 gratis or for a fee, you must give the recipients all the rights that
709 you have. You must make sure that they, too, receive or can get the
710 source code. And you must tell them their rights.
712 We protect your rights with two steps: (1) copyright the software, and
713 (2) offer you this license which gives you legal permission to copy,
714 distribute and/or modify the software.
716 Also, for each author's protection and ours, we want to make certain
717 that everyone understands that there is no warranty for this free
718 software. If the software is modified by someone else and passed on, we
719 want its recipients to know that what they have is not the original, so
720 that any problems introduced by others will not reflect on the original
721 authors' reputations.
723 The precise terms and conditions for copying, distribution and
727 @unnumberedsec TERMS AND CONDITIONS
730 @center TERMS AND CONDITIONS
735 This License Agreement applies to any program or other work which
736 contains a notice placed by the copyright holder saying it may be
737 distributed under the terms of this General Public License. The
738 ``Program'', below, refers to any such program or work, and a ``work based
739 on the Program'' means either the Program or any work containing the
740 Program or a portion of it, either verbatim or with modifications. Each
741 licensee is addressed as ``you''.
745 You may copy and distribute verbatim copies of the Program's source
746 code as you receive it, in any medium, provided that you conspicuously and
747 appropriately publish on each copy an appropriate copyright notice and
748 disclaimer of warranty; keep intact all the notices that refer to this
749 General Public License and to the absence of any warranty; and give any
750 other recipients of the Program a copy of this General Public License
751 along with the Program. You may charge a fee for the physical act of
755 You may modify your copy or copies of the Program or any portion of
756 it, and copy and distribute such modifications under the terms of Paragraph
757 1 above, provided that you also do the following:
761 cause the modified files to carry prominent notices stating that
762 you changed the files and the date of any change; and
765 cause the whole of any work that you distribute or publish, that
766 in whole or in part contains the Program or any part thereof, either
767 with or without modifications, to be licensed at no charge to all
768 third parties under the terms of this General Public License (except
769 that you may choose to grant warranty protection to some or all
770 third parties, at your option).
773 If the modified program normally reads commands interactively when
774 run, you must cause it, when started running for such interactive use
775 in the simplest and most usual way, to print or display an
776 announcement including an appropriate copyright notice and a notice
777 that there is no warranty (or else, saying that you provide a
778 warranty) and that users may redistribute the program under these
779 conditions, and telling the user how to view a copy of this General
783 You may charge a fee for the physical act of transferring a
784 copy, and you may at your option offer warranty protection in
788 Mere aggregation of another independent work with the Program (or its
789 derivative) on a volume of a storage or distribution medium does not bring
790 the other work under the scope of these terms.
793 You may copy and distribute the Program (or a portion or derivative of
794 it, under Paragraph 2) in object code or executable form under the terms of
795 Paragraphs 1 and 2 above provided that you also do one of the following:
799 accompany it with the complete corresponding machine-readable
800 source code, which must be distributed under the terms of
801 Paragraphs 1 and 2 above; or,
804 accompany it with a written offer, valid for at least three
805 years, to give any third party free (except for a nominal charge
806 for the cost of distribution) a complete machine-readable copy of the
807 corresponding source code, to be distributed under the terms of
808 Paragraphs 1 and 2 above; or,
811 accompany it with the information you received as to where the
812 corresponding source code may be obtained. (This alternative is
813 allowed only for noncommercial distribution and only if you
814 received the program in object code or executable form alone.)
817 Source code for a work means the preferred form of the work for making
818 modifications to it. For an executable file, complete source code means
819 all the source code for all modules it contains; but, as a special
820 exception, it need not include source code for modules which are standard
821 libraries that accompany the operating system on which the executable
822 file runs, or for standard header files or definitions files that
823 accompany that operating system.
826 You may not copy, modify, sublicense, distribute or transfer the
827 Program except as expressly provided under this General Public License.
828 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
829 the Program is void, and will automatically terminate your rights to use
830 the Program under this License. However, parties who have received
831 copies, or rights to use copies, from you under this General Public
832 License will not have their licenses terminated so long as such parties
833 remain in full compliance.
836 By copying, distributing or modifying the Program (or any work based
837 on the Program) you indicate your acceptance of this license to do so,
838 and all its terms and conditions.
841 Each time you redistribute the Program (or any work based on the
842 Program), the recipient automatically receives a license from the original
843 licensor to copy, distribute or modify the Program subject to these
844 terms and conditions. You may not impose any further restrictions on the
845 recipients' exercise of the rights granted herein.
849 The Free Software Foundation may publish revised and/or new versions
850 of the General Public License from time to time. Such new versions will
851 be similar in spirit to the present version, but may differ in detail to
852 address new problems or concerns.
854 Each version is given a distinguishing version number. If the Program
855 specifies a version number of the license which applies to it and ``any
856 later version'', you have the option of following the terms and conditions
857 either of that version or of any later version published by the Free
858 Software Foundation. If the Program does not specify a version number of
859 the license, you may choose any version ever published by the Free Software
863 If you wish to incorporate parts of the Program into other free
864 programs whose distribution conditions are different, write to the author
865 to ask for permission. For software which is copyrighted by the Free
866 Software Foundation, write to the Free Software Foundation; we sometimes
867 make exceptions for this. Our decision will be guided by the two goals
868 of preserving the free status of all derivatives of our free software and
869 of promoting the sharing and reuse of software generally.
879 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
880 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
881 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
882 PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
883 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
884 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
885 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
886 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
887 REPAIR OR CORRECTION.
890 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
891 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
892 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
893 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
894 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT
895 LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
896 SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
897 WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
898 ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

909 @unnumberedsec Appendix: How to Apply These Terms to Your New Programs
911 If you develop a new program, and you want it to be of the greatest
912 possible use to humanity, the best way to achieve this is to make it
913 free software which everyone can redistribute and change under these
916 To do so, attach the following notices to the program. It is safest to
917 attach them to the start of each source file to most effectively convey
918 the exclusion of warranty; and each file should have at least the
919 ``copyright'' line and a pointer to where the full notice is found.

976 @unnumbered Distribution
978 XEmacs is @dfn{free}; this means that everyone is free to use it and
979 free to redistribute it on a free basis. XEmacs is not in the public
980 domain; it is copyrighted and there are restrictions on its
981 distribution, but these restrictions are designed to permit everything
982 that a good cooperating citizen would want to do. What is not allowed
983 is to try to prevent others from further sharing any version of XEmacs
984 that they might get from you. The precise conditions are found in
985 the GNU General Public License that comes with XEmacs and also appears
986 following this section.
988 The easiest way to get a copy of XEmacs is from someone else who has it.
989 You need not ask for permission to do so, or tell any one else; just copy
992 If you have access to the Internet, you can get the latest version of
993 XEmacs from the anonymous FTP server @file{ftp.xemacs.org} in the directory
994 @file{/pub/xemacs}. It can also be found at numerous other archive
995 sites around the world; check the file @file{etc/DISTRIB} in an XEmacs
996 distribution for the latest known list.
999 @unnumberedsec Getting Other Versions of Emacs
1001 The Free Software Foundation's version of Emacs (called @dfn{FSF Emacs}
1002 in this manual and often referred to as @dfn{GNU Emacs}) is available
1003 by anonymous FTP from @file{prep.ai.mit.edu}.
1005 Win-Emacs, an older version of XEmacs that runs on Microsoft Windows
1006 and Windows NT, is available by anonymous FTP from @file{ftp.netcom.com}
1007 in the directory @file{/pub/pe/pearl}, or from @file{ftp.cica.indiana.edu}
1008 as the files @file{wemdemo*.zip} in the directory @file{/pub/pc/win3/demo}.
1010 @node Intro, Glossary, Distrib, Top
1011 @unnumbered Introduction
1013 You are reading about XEmacs, an incarnation of the advanced,
1014 self-documenting, customizable, extensible real-time display editor
1015 Emacs. XEmacs provides many powerful display and user-interface
1016 capabilities not found in other Emacsen and is mostly upwardly
1017 compatible with GNU Emacs from the Free Software Foundation
1018 (referred to as @dfn{FSF Emacs} in this manual). XEmacs also
1019 comes standard with a great number of useful packages.
1021 We say that XEmacs is a @dfn{display} editor because normally the text
1022 being edited is visible on the screen and is updated automatically as you
1023 type. @xref{Frame,Display}.
1025 We call XEmacs a @dfn{real-time} editor because the display is updated very
1026 frequently, usually after each character or pair of characters you
1027 type. This minimizes the amount of information you must keep in your
1028 head as you edit. @xref{Basic,Real-time,Basic Editing}.
1030 We call XEmacs advanced because it provides facilities that go beyond
1031 simple insertion and deletion: filling of text; automatic indentation of
1032 programs; viewing two or more files at once; and dealing in terms of
1033 characters, words, lines, sentences, paragraphs, and pages, as well as
1034 expressions and comments in several different programming languages. It is
1035 much easier to type one command meaning ``go to the end of the paragraph''
1036 than to find that spot with simple cursor keys.
1038 @dfn{Self-documenting} means that at any time you can type a special
1039 character, @kbd{Control-h}, to find out what your options are. You can
1040 also use @kbd{C-h} to find out what a command does, or to find all the
1041 commands relevant to a topic. @xref{Help}.
1043 @dfn{Customizable} means you can change the definitions of XEmacs
1044 commands. For example, if you use a programming language in
1045 which comments start with @samp{<**} and end with @samp{**>}, you can tell
1046 the XEmacs comment manipulation commands to use those strings
1047 (@pxref{Comments}). Another sort of customization is rearrangement of the
1048 command set. For example, you can set up the four basic cursor motion
1049 commands (up, down, left and right) on keys in a diamond pattern on the
1050 keyboard if you prefer. @xref{Customization}.
1052 @dfn{Extensible} means you can go beyond simple customization and
1053 write entirely new commands, programs in the Lisp language to be run by
1054 XEmacs's own Lisp interpreter. XEmacs is an ``on-line extensible''
1055 system: it is divided into many functions that call each other. You can
1056 redefine any function in the middle of an editing session and replace
1057 any part of XEmacs without making a separate copy of all of XEmacs. Most
1058 of the editing commands of XEmacs are written in Lisp; the few
1059 exceptions could have been written in Lisp but are written in C for
1060 efficiency. Only a programmer can write an extension to XEmacs, but anybody
1061 can use it afterward.
