|
|
|
606
|
|
|
607 This manual documents the use and simple customization of the XEmacs
|
|
|
608 editor. The reader is not expected to be a programmer to use this
|
|
|
609 editor, and simple customizations do not require programming skills either.
|
|
|
610 Users who are not interested in customizing XEmacs can ignore the scattered
|
|
|
611 customization hints.
|
|
|
612
|
|
|
613 This document is primarily a reference manual, but it can also be used as a
|
|
|
614 primer. However, if you are new to XEmacs, consider using the on-line,
|
|
|
615 learn-by-doing tutorial, which you get by running XEmacs and typing
|
|
|
616 @kbd{C-h t}. With it, you learn XEmacs by using XEmacs on a specially
|
|
|
617 designed file which describes commands, tells you when to try them,
|
|
|
618 and then explains the results you see. Using the tutorial gives a more vivid
|
|
|
619 introduction than the printed manual. Also consider reading the XEmacs
|
|
|
620 New User's Guide, which is intended specifically as an introductory
|
|
|
621 manual rather than as a reference guide.
|
|
|
622
|
|
|
623 On first reading, just skim chapters one and two, which describe the
|
|
|
624 notational conventions of the manual and the general appearance of the
|
|
|
625 XEmacs display frame. Note which questions are answered in these chapters,
|
|
|
626 so you can refer back later. After reading chapter four you should
|
|
|
627 practice the commands there. The next few chapters describe fundamental
|
|
|
628 techniques and concepts that are used constantly. You need to understand
|
|
|
629 them thoroughly, experimenting with them if necessary.
|
|
|
630
|
|
|
631 To find the documentation on a particular command, look in the index.
|
|
|
632 Keys (character commands) and command names have separate indexes. There
|
|
|
633 is also a glossary, with a cross reference for each term.
|
|
|
634
|
|
|
635 @ignore
|
|
|
636 If you know vaguely what the command
|
|
|
637 does, look in the command summary. The command summary contains a line or
|
|
|
638 two about each command, and a cross reference to the section of the
|
|
|
639 manual that describes the command in more detail; related commands
|
|
|
640 are grouped together.
|
|
|
641 @end ignore
|
|
|
642
|
|
|
643 This manual comes in two forms: the published form and the Info form.
|
|
|
644 The Info form is for on-line perusal with the INFO program; it is
|
|
|
645 distributed along with XEmacs. Both forms contain substantially the
|
|
|
646 same text and are generated from a common source file, which is also
|
|
|
647 distributed along with XEmacs.
|
|
|
648
|
|
|
649 XEmacs is a member of the Emacs editor family. There are many Emacs
|
|
|
650 editors, all sharing common principles of organization. For information on
|
|
|
651 the underlying philosophy of Emacs and the lessons learned from its
|
|
|
652 development, write for a copy of AI memo 519a, ``Emacs, the Extensible,
|
|
|
653 Customizable Self-Documenting Display Editor'', to Publications Department,
|
|
|
654 Artificial Intelligence Lab, 545 Tech Square, Cambridge, MA 02139, USA. At
|
|
|
655 last report they charge $2.25 per copy. Another useful publication is LCS
|
|
|
656 TM-165, ``A Cookbook for an Emacs'', by Craig Finseth, available from
|
|
|
657 Publications Department, Laboratory for Computer Science, 545 Tech Square,

660 This manual is for XEmacs installed on UNIX systems. XEmacs also
|
|

661 exists on Microsoft Windows and Windows NT as Win-Emacs (which is

|
662 actually based on Lucid Emacs 19.6, an older incarnation of XEmacs).

|
|
|
682 The license agreements of most software companies try to keep users
|
|
|
683 at the mercy of those companies. By contrast, our General Public
|
|
|
684 License is intended to guarantee your freedom to share and change free
|
|
|
685 software---to make sure the software is free for all its users. The
|
|
|
686 General Public License applies to the Free Software Foundation's
|
|
|
687 software and to any other program whose authors commit to using it.
|
|
|
688 You can use it for your programs, too.
|
|
|
689
|
|
|
690 When we speak of free software, we are referring to freedom, not
|
|
|
691 price. Specifically, the General Public License is designed to make
|
|
|
692 sure that you have the freedom to give away or sell copies of free
|
|
|
693 software, that you receive source code or can get it if you want it,
|
|
|
694 that you can change the software or use pieces of it in new free
|
|
|
695 programs; and that you know you can do these things.
|
|
|
696
|
|
|
697 To protect your rights, we need to make restrictions that forbid
|
|
|
698 anyone to deny you these rights or to ask you to surrender the rights.
|
|
|
699 These restrictions translate to certain responsibilities for you if you
|
|
|
700 distribute copies of the software, or if you modify it.
|
|
|
701
|
|
|
702 For example, if you distribute copies of a such a program, whether
|

711 Also, for each author's protection and ours, we want to make certain

712 that everyone understands that there is no warranty for this free

|
|
713 software. If the software is modified by someone else and passed on, we
|
|
|
714 want its recipients to know that what they have is not the original, so

|

715 that any problems introduced by others will not reflect on the original

716 authors' reputations.

|
|
|
905
|
|
|
906 If you develop a new program, and you want it to be of the greatest
|
|
|
907 possible use to humanity, the best way to achieve this is to make it
|
|
|
908 free software which everyone can redistribute and change under these
|
|
|
909 terms.
|
|
|
910
|
|
|
911 To do so, attach the following notices to the program. It is safest to
|
|
|
912 attach them to the start of each source file to most effectively convey
|
|
|
913 the exclusion of warranty; and each file should have at least the
|
|
|
914 ``copyright'' line and a pointer to where the full notice is found.

973 XEmacs is @dfn{free}; this means that everyone is free to use it and

|
|
974 free to redistribute it on a free basis. XEmacs is not in the public
|
|

|
|
|
976 distribution, but these restrictions are designed to permit everything
|
|

977 that a good cooperating citizen would want to do. What is not allowed
|
|

978 is to try to prevent others from further sharing any version of XEmacs
|

979 that they might get from you. The precise conditions are found in

1006 @unnumbered Introduction
|
|
|
1007
|
|
|
1008 You are reading about XEmacs, an incarnation of the advanced,
|
|
|
1009 self-documenting, customizable, extensible real-time display editor
|
|
|
1010 Emacs. XEmacs provides many powerful display and user-interface
|
|
|
1011 capabilities not found in other Emacsen and is mostly upwardly
|
|
|
1012 compatible with GNU Emacs from the Free Software Foundation
|
|
|
1013 (referred to as @dfn{FSF Emacs} in this manual). XEmacs also
|
|
|
1014 comes standard with a great number of useful packages.
|
|
|
1015
|
|
|
1016 We say that XEmacs is a @dfn{display} editor because normally the text
|
|
|
1017 being edited is visible on the screen and is updated automatically as you
|
|
|
1018 type. @xref{Frame,Display}.
|
|
|
1019
|
|
|
1020 We call XEmacs a @dfn{real-time} editor because the display is updated very
|
|
|
1021 frequently, usually after each character or pair of characters you
|
|
|
1022 type. This minimizes the amount of information you must keep in your
|
|
|
1023 head as you edit. @xref{Basic,Real-time,Basic Editing}.
|
|
|
1024
|
|
|
1025 We call XEmacs advanced because it provides facilities that go beyond
|
|
|
1026 simple insertion and deletion: filling of text; automatic indentation of
|
|
|
1027 programs; viewing two or more files at once; and dealing in terms of
|
|
|
1028 characters, words, lines, sentences, paragraphs, and pages, as well as
|
|
|
1029 expressions and comments in several different programming languages. It is
|
|
|
1030 much easier to type one command meaning ``go to the end of the paragraph''
|
|
|
1031 than to find that spot with simple cursor keys.
|
|
|
1032
|
|
|
1033 @dfn{Self-documenting} means that at any time you can type a special
|
|
|
1034 character, @kbd{Control-h}, to find out what your options are. You can
|
|
|
1035 also use @kbd{C-h} to find out what a command does, or to find all the
|
|
|
1036 commands relevant to a topic. @xref{Help}.
|
|
|
1037
|
|
|
1038 @dfn{Customizable} means you can change the definitions of XEmacs
|

1039 commands. For example, if you use a programming language in
|
|
|
1040 which comments start with @samp{<**} and end with @samp{**>}, you can tell
|
|
|
1041 the XEmacs comment manipulation commands to use those strings
|
|
|
1042 (@pxref{Comments}). Another sort of customization is rearrangement of the
|
|
|
1043 command set. For example, you can set up the four basic cursor motion
|
|
|
1044 commands (up, down, left and right) on keys in a diamond pattern on the
|
|
|
1045 keyboard if you prefer. @xref{Customization}.
|
|
|
1046
|
|
|
1047 @dfn{Extensible} means you can go beyond simple customization and
|
|
|
1048 write entirely new commands, programs in the Lisp language to be run by
|
|
|
1049 XEmacs's own Lisp interpreter. XEmacs is an ``on-line extensible''
|
|
|
1050 system: it is divided into many functions that call each other. You can
|
|
|
1051 redefine any function in the middle of an editing session and replace
|
|
|
1052 any part of XEmacs without making a separate copy of all of XEmacs. Most
|
|
|
1053 of the editing commands of XEmacs are written in Lisp; the few
|
|
|
1054 exceptions could have been written in Lisp but are written in C for
|
|
|
1055 efficiency. Only a programmer can write an extension to XEmacs, but anybody
|
|
|
1056 can use it afterward.
