836 | @unnumbered Preface | |
837 | ||
838 | This manual documents the use and simple customization of the Emacs | |
839 | editor. The reader is not expected to be a programmer; simple | |
840 | customizations do not require programming skill. But the user who is not | |
841 | interested in customizing can ignore the scattered customization hints. | |
842 | ||
843 | This is primarily a reference manual, but can also be used as a | |
844 | primer. For complete beginners, it is a good idea to start with the | |
845 | on-line, learn-by-doing tutorial, before reading the manual. To run the | |
846 | tutorial, start Emacs and type @kbd{C-h t}. This way you can learn | |
847 | Emacs by using Emacs on a specially designed file which describes | |
848 | commands, tells you when to try them, and then explains the results you | |

851 | On first reading, just skim chapters 1 and 2, which describe the | |
852 | notational conventions of the manual and the general appearance of the | |
853 | Emacs display screen. Note which questions are answered in these | |
854 | chapters, so you can refer back later. After reading chapter 4, you | |
855 | should practice the commands there. The next few chapters describe | |
856 | fundamental techniques and concepts that are used constantly. You need | |
857 | to understand them thoroughly, experimenting with them if necessary. | |
858 | ||
859 | Chapters 14 through 19 describe intermediate-level features that are | |
860 | useful for all kinds of editing. Chapter 20 and following chapters | |
861 | describe features that you may or may not want to use; read those | |
862 | chapters when you need them. | |
863 | ||
864 | Read the Trouble chapter if Emacs does not seem to be working | |
865 | properly. It explains how to cope with some common problems | |
866 | (@pxref{Lossage}), as well as when and how to report Emacs bugs | |
867 | (@pxref{Bugs}). | |

869 | To find the documentation on a particular command, look in the index. |
870 | Keys (character commands) and command names have separate indexes. There | |
871 | is also a glossary, with a cross reference for each term. | |
872 | ||
873 | This manual is available as a printed book and also as an Info file. | |
874 | The Info file is for on-line perusal with the Info program, which will | |
875 | be the principal way of viewing documentation on-line in the GNU system. | |
876 | Both the Info file and the Info program itself are distributed along | |
877 | with GNU Emacs. The Info file and the printed book contain | |
878 | substantially the same text and are generated from the same source | |
879 | files, which are also distributed along with GNU Emacs. | |

881 | GNU Emacs is a member of the Emacs editor family. There are many Emacs | |
882 | editors, all sharing common principles of organization. For information on | |
883 | the underlying philosophy of Emacs and the lessons learned from its | |
884 | development, write for a copy of AI memo 519a, ``Emacs, the Extensible, | |
885 | Customizable Self-Documenting Display Editor,'' to Publications Department, | |
886 | Artificial Intelligence Lab, 545 Tech Square, Cambridge, MA 02139, USA@. At | |
887 | last report they charge $2.25 per copy. Another useful publication is LCS | |
888 | TM-165, ``A Cookbook for an Emacs,'' by Craig Finseth, available from | |
889 | Publications Department, Laboratory for Computer Science, 545 Tech Square, | |
890 | Cambridge, MA 02139, USA@. The price today is $3. | |

892 | This edition of the manual is intended for use with GNU Emacs installed | |
893 | on GNU and Unix systems. GNU Emacs can also be used on VMS, MS-DOS | |
894 | (also called MS-DOG), Windows NT, and Windows 95 systems. Those systems use | |
895 | different file name syntax; in addition, VMS and MS-DOS do not support | |
896 | all GNU Emacs features. We don't try to describe VMS usage in this | |
897 | manual. @xref{MS-DOS}, for information about using Emacs on MS-DOS. | |

902 | ||
903 | GNU Emacs is @dfn{free software}; this means that everyone is free to | |
904 | use it and free to redistribute it on certain conditions. GNU Emacs is | |
905 | not in the public domain; it is copyrighted and there are restrictions | |
906 | on its distribution, but these restrictions are designed to permit | |
907 | everything that a good cooperating citizen would want to do. What is | |
908 | not allowed is to try to prevent others from further sharing any version | |
909 | of GNU Emacs that they might get from you. The precise conditions are | |
910 | found in the GNU General Public License that comes with Emacs and also | |
911 | appears following this section. | |
912 | ||
913 | One way to get a copy of GNU Emacs is from someone else who has it. You | |
914 | need not ask for our permission to do so, or tell any one else; just | |
915 | copy it. If you have access to the Internet, you can get the latest | |
916 | distribution version of GNU Emacs by anonymous FTP; see the file | |
917 | @file{etc/FTP} in the Emacs distribution for more information. | |
918 | ||
919 | You may also receive GNU Emacs when you buy a computer. Computer | |
920 | manufacturers are free to distribute copies on the same terms that apply to | |
921 | everyone else. These terms require them to give you the full sources, | |
922 | including whatever changes they may have made, and to permit you to | |
923 | redistribute the GNU Emacs received from them under the usual terms of the | |
924 | General Public License. In other words, the program must be free for you | |
925 | when you get it, not just free for the manufacturer. | |
926 | ||
927 | You can also order copies of GNU Emacs from the Free Software Foundation | |
928 | on CD-ROM@. This is a convenient and reliable way to get a copy; it is | |
929 | also a good way to help fund our work. (The Foundation has always | |
930 | received most of its funds in this way.) An order form is included in | |
931 | the file @file{etc/ORDERS} in the Emacs distribution, and on our web | |
932 | site in @url{http://www.gnu.org/order/order.html}. For further | |

946 | If you find GNU Emacs useful, please @strong{send a donation} to the | |
947 | Free Software Foundation to support our work. Donations to the Free | |
948 | Software Foundation are tax deductible in the US. If you use GNU Emacs | |
949 | at your workplace, please suggest that the company make a donation. If | |
950 | company policy is unsympathetic to the idea of donating to charity, you | |
951 | might instead suggest ordering a CD-ROM from the Foundation | |
952 | occasionally, or subscribing to periodic updates. | |

1001 | ||
1002 | @display | |
1003 | Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc. | |
1004 | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | |
1005 | ||
1006 | Everyone is permitted to copy and distribute verbatim copies | |
1007 | of this license document, but changing it is not allowed. | |
1008 | @end display | |
1009 | ||
1010 | @unnumberedsec Preamble | |
1011 | ||
1012 | The licenses for most software are designed to take away your | |
1013 | freedom to share and change it. By contrast, the GNU General Public | |
1014 | License is intended to guarantee your freedom to share and change free | |
1015 | software---to make sure the software is free for all its users. This | |
1016 | General Public License applies to most of the Free Software | |
1017 | Foundation's software and to any other program whose authors commit to | |
1018 | using it. (Some other Free Software Foundation software is covered by | |
1019 | the GNU Library General Public License instead.) You can apply it to | |
1020 | your programs, too. | |
1021 | ||
1022 | When we speak of free software, we are referring to freedom, not | |
1023 | price. Our General Public Licenses are designed to make sure that you | |
1024 | have the freedom to distribute copies of free software (and charge for | |
1025 | this service if you wish), that you receive source code or can get it | |
1026 | if you want it, that you can change the software or use pieces of it | |
1027 | in new free programs; and that you know you can do these things. | |
1028 | ||
1029 | To protect your rights, we need to make restrictions that forbid | |
1030 | anyone to deny you these rights or to ask you to surrender the rights. | |
1031 | These restrictions translate to certain responsibilities for you if you | |
1032 | distribute copies of the software, or if you modify it. | |
1033 | ||
1034 | For example, if you distribute copies of such a program, whether | |
1035 | gratis or for a fee, you must give the recipients all the rights that | |
1036 | you have. You must make sure that they, too, receive or can get the | |
1037 | source code. And you must show them these terms so they know their | |
1038 | rights. | |
1039 | ||
1040 | We protect your rights with two steps: (1) copyright the software, and | |
1041 | (2) offer you this license which gives you legal permission to copy, | |
1042 | distribute and/or modify the software. | |
1043 | ||
1044 | Also, for each author's protection and ours, we want to make certain | |
1045 | that everyone understands that there is no warranty for this free | |
1046 | software. If the software is modified by someone else and passed on, we | |
1047 | want its recipients to know that what they have is not the original, so | |
1048 | that any problems introduced by others will not reflect on the original | |
1049 | authors' reputations. | |
1050 | ||
1051 | Finally, any free program is threatened constantly by software | |
1052 | patents. We wish to avoid the danger that redistributors of a free | |
1053 | program will individually obtain patent licenses, in effect making the | |
1054 | program proprietary. To prevent this, we have made it clear that any | |
1055 | patent must be licensed for everyone's free use or not licensed at all. | |
1056 | ||
1057 | The precise terms and conditions for copying, distribution and | |
1058 | modification follow. | |

1069 | This License applies to any program or other work which contains | |
1070 | a notice placed by the copyright holder saying it may be distributed | |
df9d7630 | 1071 | under the terms of this General Public License. The ``Program,'' below, |
3f973d9b AI |
1072 | refers to any such program or work, and a ``work based on the Program'' |
1073 | means either the Program or any derivative work under copyright law: | |
1074 | that is to say, a work containing the Program or a portion of it, | |
1075 | either verbatim or with modifications and/or translated into another | |
1076 | language. (Hereinafter, translation is included without limitation in | |
df9d7630 | 1077 | the term ``modification.'') Each licensee is addressed as ``you.'' |
3f973d9b AI |
1078 | |
1079 | Activities other than copying, distribution and modification are not | |
1080 | covered by this License; they are outside its scope. The act of | |
1081 | running the Program is not restricted, and the output from the Program | |
1082 | is covered only if its contents constitute a work based on the | |
1083 | Program (independent of having been made by running the Program). | |
1084 | Whether that is true depends on what the Program does. | |
1085 | ||
1086 | @item | |
1087 | You may copy and distribute verbatim copies of the Program's | |
1088 | source code as you receive it, in any medium, provided that you | |
1089 | conspicuously and appropriately publish on each copy an appropriate | |
1090 | copyright notice and disclaimer of warranty; keep intact all the | |
1091 | notices that refer to this License and to the absence of any warranty; | |
1092 | and give any other recipients of the Program a copy of this License | |
1093 | along with the Program. | |
1094 | ||
1095 | You may charge a fee for the physical act of transferring a copy, and | |
1096 | you may at your option offer warranty protection in exchange for a fee. | |
1097 | ||
1098 | @item | |
1099 | You may modify your copy or copies of the Program or any portion | |
1100 | of it, thus forming a work based on the Program, and copy and | |
1101 | distribute such modifications or work under the terms of Section 1 | |
1102 | above, provided that you also meet all of these conditions: | |
1103 | ||
1104 | @enumerate a | |
1105 | @item | |
1106 | You must cause the modified files to carry prominent notices | |
1107 | stating that you changed the files and the date of any change. | |
1108 | ||
1109 | @item | |
1110 | You must cause any work that you distribute or publish, that in | |
1111 | whole or in part contains or is derived from the Program or any | |
1112 | part thereof, to be licensed as a whole at no charge to all third | |
1113 | parties under the terms of this License. | |
1114 | ||
1115 | @item | |
1116 | If the modified program normally reads commands interactively | |
1117 | when run, you must cause it, when started running for such | |
1118 | interactive use in the most ordinary way, to print or display an | |
1119 | announcement including an appropriate copyright notice and a | |
1120 | notice that there is no warranty (or else, saying that you provide | |
1121 | a warranty) and that users may redistribute the program under | |
1122 | these conditions, and telling the user how to view a copy of this | |
1123 | License. (Exception: if the Program itself is interactive but | |
1124 | does not normally print such an announcement, your work based on | |
1125 | the Program is not required to print an announcement.) | |
1126 | @end enumerate | |
1127 | ||
1128 | These requirements apply to the modified work as a whole. If | |
1129 | identifiable sections of that work are not derived from the Program, | |
1130 | and can be reasonably considered independent and separate works in | |
1131 | themselves, then this License, and its terms, do not apply to those | |
1132 | sections when you distribute them as separate works. But when you | |
1133 | distribute the same sections as part of a whole which is a work based | |
1134 | on the Program, the distribution of the whole must be on the terms of | |
1135 | this License, whose permissions for other licensees extend to the | |
1136 | entire whole, and thus to each and every part regardless of who wrote it. | |
1137 | ||
1138 | Thus, it is not the intent of this section to claim rights or contest | |
1139 | your rights to work written entirely by you; rather, the intent is to | |
1140 | exercise the right to control the distribution of derivative or | |
1141 | collective works based on the Program. | |
1142 | ||
1143 | In addition, mere aggregation of another work not based on the Program | |
1144 | with the Program (or with a work based on the Program) on a volume of | |
1145 | a storage or distribution medium does not bring the other work under | |
1146 | the scope of this License. | |
1147 | ||
1148 | @item | |
1149 | You may copy and distribute the Program (or a work based on it, | |
1150 | under Section 2) in object code or executable form under the terms of | |
1151 | Sections 1 and 2 above provided that you also do one of the following: | |
1152 | ||
1153 | @enumerate a | |
1154 | @item | |
1155 | Accompany it with the complete corresponding machine-readable | |
1156 | source code, which must be distributed under the terms of Sections | |
1157 | 1 and 2 above on a medium customarily used for software interchange; or, | |
1158 | ||
1159 | @item | |
1160 | Accompany it with a written offer, valid for at least three | |
1161 | years, to give any third party, for a charge no more than your | |
1162 | cost of physically performing source distribution, a complete | |
1163 | machine-readable copy of the corresponding source code, to be | |
1164 | distributed under the terms of Sections 1 and 2 above on a medium | |
1165 | customarily used for software interchange; or, | |
1166 | ||
1167 | @item | |
1168 | Accompany it with the information you received as to the offer | |
1169 | to distribute corresponding source code. (This alternative is | |
1170 | allowed only for noncommercial distribution and only if you | |
1171 | received the program in object code or executable form with such | |
1172 | an offer, in accord with Subsection b above.) | |
1173 | @end enumerate | |
1174 | ||
1175 | The source code for a work means the preferred form of the work for | |
1176 | making modifications to it. For an executable work, complete source | |
1177 | code means all the source code for all modules it contains, plus any | |
1178 | associated interface definition files, plus the scripts used to | |
1179 | control compilation and installation of the executable. However, as a | |
1180 | special exception, the source code distributed need not include | |
1181 | anything that is normally distributed (in either source or binary | |
1182 | form) with the major components (compiler, kernel, and so on) of the | |
1183 | operating system on which the executable runs, unless that component | |
1184 | itself accompanies the executable. | |
1185 | ||
1186 | If distribution of executable or object code is made by offering | |
1187 | access to copy from a designated place, then offering equivalent | |
1188 | access to copy the source code from the same place counts as | |
1189 | distribution of the source code, even though third parties are not | |
1190 | compelled to copy the source along with the object code. | |
1191 | ||
1192 | @item | |
1193 | You may not copy, modify, sublicense, or distribute the Program | |
1194 | except as expressly provided under this License. Any attempt | |
1195 | otherwise to copy, modify, sublicense or distribute the Program is | |
1196 | void, and will automatically terminate your rights under this License. | |
1197 | However, parties who have received copies, or rights, from you under | |
1198 | this License will not have their licenses terminated so long as such | |
1199 | parties remain in full compliance. | |
1200 | ||
1201 | @item | |
1202 | You are not required to accept this License, since you have not | |
1203 | signed it. However, nothing else grants you permission to modify or | |
1204 | distribute the Program or its derivative works. These actions are | |
1205 | prohibited by law if you do not accept this License. Therefore, by | |
1206 | modifying or distributing the Program (or any work based on the | |
1207 | Program), you indicate your acceptance of this License to do so, and | |
1208 | all its terms and conditions for copying, distributing or modifying | |
1209 | the Program or works based on it. | |
1210 | ||
1211 | @item | |
1212 | Each time you redistribute the Program (or any work based on the | |
1213 | Program), the recipient automatically receives a license from the | |
1214 | original licensor to copy, distribute or modify the Program subject to | |
1215 | these terms and conditions. You may not impose any further | |
1216 | restrictions on the recipients' exercise of the rights granted herein. | |
1217 | You are not responsible for enforcing compliance by third parties to | |
1218 | this License. | |
1219 | ||
1220 | @item | |
1221 | If, as a consequence of a court judgment or allegation of patent | |
1222 | infringement or for any other reason (not limited to patent issues), | |
1223 | conditions are imposed on you (whether by court order, agreement or | |
1224 | otherwise) that contradict the conditions of this License, they do not | |
1225 | excuse you from the conditions of this License. If you cannot | |
1226 | distribute so as to satisfy simultaneously your obligations under this | |
1227 | License and any other pertinent obligations, then as a consequence you | |
1228 | may not distribute the Program at all. For example, if a patent | |
1229 | license would not permit royalty-free redistribution of the Program by | |
1230 | all those who receive copies directly or indirectly through you, then | |
1231 | the only way you could satisfy both it and this License would be to | |
1232 | refrain entirely from distribution of the Program. | |
1233 | ||
1234 | If any portion of this section is held invalid or unenforceable under | |
1235 | any particular circumstance, the balance of the section is intended to | |
1236 | apply and the section as a whole is intended to apply in other | |
1237 | circumstances. | |
1238 | ||
1239 | It is not the purpose of this section to induce you to infringe any | |
1240 | patents or other property right claims or to contest validity of any | |
1241 | such claims; this section has the sole purpose of protecting the | |
1242 | integrity of the free software distribution system, which is | |
1243 | implemented by public license practices. Many people have made | |

1323 | @unnumberedsec How to Apply These Terms to Your New Programs | |
1324 | ||
1325 | If you develop a new program, and you want it to be of the greatest | |
1326 | possible use to the public, the best way to achieve this is to make it | |
1327 | free software which everyone can redistribute and change under these terms. | |
1328 | ||
1329 | To do so, attach the following notices to the program. It is safest | |
1330 | to attach them to the start of each source file to most effectively | |
1331 | convey the exclusion of warranty; and each file should have at least | |
1332 | the ``copyright'' line and a pointer to where the full notice is found. | |

1397 | @unnumbered Introduction |
1398 | ||
1399 | You are reading about GNU Emacs, the GNU incarnation of the advanced, | |
1400 | self-documenting, customizable, extensible real-time display editor Emacs. | |
1401 | (The `G' in `GNU' is not silent.) | |
1402 | ||
1403 | We say that Emacs is a @dfn{display} editor because normally the text | |
1404 | being edited is visible on the screen and is updated automatically as you | |
1405 | type your commands. @xref{Screen,Display}. | |
1406 | ||
1407 | We call it a @dfn{real-time} editor because the display is updated very | |
1408 | frequently, usually after each character or pair of characters you | |
1409 | type. This minimizes the amount of information you must keep in your | |
1410 | head as you edit. @xref{Basic,Real-time,Basic Editing}. | |
1411 | ||
1412 | We call Emacs advanced because it provides facilities that go beyond | |
1413 | simple insertion and deletion: controlling subprocesses; automatic | |
1414 | indentation of programs; viewing two or more files at once; editing | |
1415 | formatted text; and dealing in terms of characters, words, lines, | |
1416 | sentences, paragraphs, and pages, as well as expressions and comments in | |
1417 | several different programming languages. | |
1418 | ||
1419 | @dfn{Self-documenting} means that at any time you can type a special | |
1420 | character, @kbd{Control-h}, to find out what your options are. You can | |
1421 | also use it to find out what any command does, or to find all the commands | |
1422 | that pertain to a topic. @xref{Help}. | |
1423 | ||
1424 | @dfn{Customizable} means that you can change the definitions of Emacs | |
1425 | commands in little ways. For example, if you use a programming language in | |
1426 | which comments start with @samp{<**} and end with @samp{**>}, you can tell | |
1427 | the Emacs comment manipulation commands to use those strings | |
1428 | (@pxref{Comments}). Another sort of customization is rearrangement of the | |
1429 | command set. For example, if you prefer the four basic cursor motion | |
1430 | commands (up, down, left and right) on keys in a diamond pattern on the | |
1431 | keyboard, you can rebind the keys that way. @xref{Customization}. | |
1432 | ||
1433 | @dfn{Extensible} means that you can go beyond simple customization and | |
1434 | write entirely new commands, programs in the Lisp language to be run by | |
1435 | Emacs's own Lisp interpreter. Emacs is an ``on-line extensible'' | |
1436 | system, which means that it is divided into many functions that call | |
1437 | each other, any of which can be redefined in the middle of an editing | |
1438 | session. Almost any part of Emacs can be replaced without making a | |
1439 | separate copy of all of Emacs. Most of the editing commands of Emacs | |
c4a9bc8e | 1440 | are written in Lisp; the few exceptions could have been written |
3f973d9b AI |
1441 | in Lisp but are written in C for efficiency. Although only a programmer |
1442 | can write an extension, anybody can use it afterward. If you want to | |
1443 | learn Emacs Lisp programming, we recommend the @cite{Introduction to | |
1444 | Emacs Lisp} by Robert J. Chassell, also published by the Free Software | |
1445 | Foundation. | |
1446 | ||
1447 | When run under the X Window System, Emacs provides its own menus and | |
1448 | convenient bindings to mouse buttons. But Emacs can provide many of the | |
1449 | benefits of a window system on a text-only terminal. For instance, you | |
1450 | can look at or edit several files at once, move text between files, and | |
1451 | edit files while running shell commands. | |
