26 | ;; How to Install GNUS: |
27 | ;; (0) First of all, remove GNUS related OLD *.elc files (at least | |
28 | ;; nntp.elc). | |
29 | ;; (1) Unshar gnus.el, gnuspost.el, gnusmail.el, gnusmisc.el, and | |
30 | ;; nntp.el. | |
31 | ;; (2) byte-compile-file nntp.el, gnus.el, gnuspost.el, gnusmail.el, | |
32 | ;; and gnusmisc.el. If you have a local news spool, | |
33 | ;; byte-compile-file nnspool.el, too. | |
34 | ;; (3) Define three environment variables in .login file as follows: | |
35 | ;; | |
36 | ;; setenv NNTPSERVER flab | |
37 | ;; setenv DOMAINNAME "stars.flab.Fujitsu.CO.JP" | |
38 | ;; setenv ORGANIZATION "Fujitsu Laboratories Ltd., Kawasaki, Japan." | |
39 | ;; | |
40 | ;; Or instead, define lisp variables in your .emacs, site-init.el, | |
41 | ;; or default.el as follows: | |
42 | ;; | |
43 | ;; (setq gnus-nntp-server "flab") | |
44 | ;; (setq gnus-local-domain "stars.flab.Fujitsu.CO.JP") | |
45 | ;; (setq gnus-local-organization "Fujitsu Laboratories Ltd., ...") | |
46 | ;; | |
47 | ;; If the function (system-name) returns the full internet name, | |
48 | ;; you don't have to define the domain. | |
49 | ;; | |
50 | ;; (4) You may have to define NNTP service name as number 119. | |
51 | ;; | |
52 | ;; (setq gnus-nntp-service 119) | |
53 | ;; | |
54 | ;; Or, if you'd like to use a local news spool directly in stead | |
55 | ;; of NNTP, install nnspool.el and set the variable to nil as | |
56 | ;; follows: | |
57 | ;; | |
58 | ;; (setq gnus-nntp-service nil) | |
59 | ;; | |
60 | ;; (5) If you'd like to use the GENERICFROM feature like the Bnews, | |
61 | ;; define the variable as follows: | |
62 | ;; | |
63 | ;; (setq gnus-use-generic-from t) | |
64 | ;; | |
65 | ;; (6) Define autoload entries in .emacs file as follows: | |
66 | ;; | |
67 | ;; (autoload 'gnus "gnus" "Read network news." t) | |
68 | ;; (autoload 'gnus-post-news "gnuspost" "Post a news." t) | |
69 | ;; | |
70 | ;; (7) Read nntp.el if you have problems with NNTP or kanji handling. | |
71 | ;; | |
72 | ;; (8) Install mhspool.el, tcp.el, and tcp.c if it is necessary. | |
73 | ;; | |
74 | ;; mhspool.el is a package for reading articles or mail in your | |
75 | ;; private directory using GNUS. | |
76 | ;; | |
77 | ;; tcp.el and tcp.c are necessary if and only if your Emacs does | |
78 | ;; not have the function `open-network-stream' which is used for | |
79 | ;; communicating with NNTP server inside Emacs. | |
80 | ;; | |
81 | ;; (9) Install an Info file generated from the texinfo manual gnus.texinfo. | |
82 | ;; | |
83 | ;; If you are not allowed to create the Info file to the standard | |
84 | ;; Info-directory, create it in your private directory and set the | |
85 | ;; variable gnus-info-directory to that directory. | |

1009 | The name of the host running NNTP server is asked for if no default | |
1010 | host is specified. It is also possible to choose another NNTP server | |
1011 | even when the default server is defined by giving a prefix argument to | |
1012 | the command `\\[gnus]'. | |
1013 | ||
1014 | If an NNTP server is preceded by a colon such as `:Mail', the user's | |
1015 | private directory `~/Mail' is used as a news spool. This makes it | |
1016 | possible to read mail stored in MH folders or articles saved by GNUS. | |
1017 | File names of mail or articles must consist of only numeric | |
1018 | characters. Otherwise, they are ignored. | |
1019 | ||
1020 | If there is a file named `~/.newsrc-SERVER', it is used as the | |
1021 | startup file instead of standard one when talking to SERVER. It is | |
1022 | possible to talk to many hosts by using different startup files for | |
1023 | each. | |
1024 | ||
1025 | Option `-n' of the options line in the startup file is recognized | |
1026 | properly the same as the Bnews system. For example, if the options | |
1027 | line is `options -n !talk talk.rumors', newsgroups under the `talk' | |
1028 | hierarchy except for `talk.rumors' are ignored while checking new | |
1029 | newsgroups. | |
1030 | ||
1031 | If there is a file named `~/.signature-DISTRIBUTION', it is used as | |
1032 | signature file instead of standard one when posting a news in | |
1033 | DISTRIBUTION. | |
1034 | ||
1035 | If an Info file generated from `gnus.texinfo' is installed, you can | |
1036 | read an appropriate Info node of the Info file according to the | |
b027f415 | 1037 | current major mode of GNUS by \\[gnus-info-find-node]. |
745bc783 JB |
1038 | |
1039 | The variable `gnus-version', `nntp-version', `nnspool-version', and | |
1040 | `mhspool-version' have the version numbers of this version of gnus.el, | |
1041 | nntp.el, nnspool.el, and mhspoo.el, respectively. | |
1042 | ||
1043 | User customizable variables: | |
1044 | gnus-nntp-server | |
1045 | Specifies the name of the host running the NNTP server. If its | |
1046 | value is a string such as `:DIRECTORY', the user's private | |
b027f415 RS |
1047 | DIRECTORY is used as a news spool. The variable is initialized |
1048 | from the NNTPSERVER environment variable. | |
745bc783 JB |
1049 | |
1050 | gnus-nntp-service | |
b027f415 RS |
1051 | Specifies a NNTP service name. It is usually \"nntp\" or 119. |
1052 | Nil forces GNUS to use a local news spool if the variable | |
1053 | `gnus-nntp-server' is set to the local host name. | |
745bc783 JB |
1054 | |
1055 | gnus-startup-file | |
b027f415 RS |
1056 | Specifies a startup file (.newsrc). If there is a file named |
1057 | `.newsrc-SERVER', it's used instead when talking to SERVER. I | |
745bc783 JB |
1058 | recommend you to use the server specific file, if you'd like to |
1059 | talk to many servers. Especially if you'd like to read your | |
1060 | private directory, the name of the file must be | |
1061 | `.newsrc-:DIRECTORY'. | |
1062 | ||
1063 | gnus-signature-file | |
b027f415 | 1064 | Specifies a signature file (.signature). If there is a file named |
745bc783 | 1065 | `.signature-DISTRIBUTION', it's used instead when posting an |
b027f415 RS |
1066 | article in DISTRIBUTION. Set the variable to nil to prevent |
1067 | appending the file automatically. If you use an NNTP inews which | |
745bc783 JB |
1068 | comes with the NNTP package, you may have to set the variable to |
1069 | nil. | |
1070 | ||
1071 | gnus-use-cross-reference | |
1072 | Specifies what to do with cross references (Xref: field). If it | |
1073 | is nil, cross references are ignored. If it is t, articles in | |
1074 | subscribed newsgroups are only marked as read. Otherwise, if it | |
1075 | is not nil nor t, articles in all newsgroups are marked as read. | |
1076 | ||
1077 | gnus-use-followup-to | |
1078 | Specifies what to do with followup-to: field. If it is nil, its | |
1079 | value is ignored. If it is non-nil, its value is used as followup | |
1080 | newsgroups. Especially, if it is t and field value is `poster', | |
1081 | your confirmation is required. | |
1082 | ||
1083 | gnus-author-copy | |
1084 | Specifies a file name to save a copy of article you posted using | |
1085 | FCC: field. If the first character of the value is `|', the | |
1086 | contents of the article is piped out to a program specified by the | |
1087 | rest of the value. The variable is initialized from the | |
1088 | AUTHORCOPY environment variable. | |
1089 | ||
1090 | gnus-author-copy-saver | |
1091 | Specifies a function to save an author copy. The function is | |
1092 | called with a file name. The default function `rmail-output' | |
1093 | saves in Unix mail format. | |
1094 | ||
1095 | gnus-kill-file-name | |
1096 | Use specified file name as a KILL file (default to `KILL'). | |
1097 | ||
1098 | gnus-novice-user | |
1099 | Non-nil means that you are a novice to USENET. If non-nil, | |
1100 | verbose messages may be displayed or your confirmations may be | |
1101 | required. | |
1102 | ||
1103 | gnus-interactive-post | |
1104 | Non-nil means that newsgroup, subject and distribution are asked | |
1105 | for interactively when posting a new article. | |
1106 | ||
1107 | gnus-use-full-window | |
1108 | Non-nil means to take up the entire screen of Emacs. | |
1109 | ||
1110 | gnus-window-configuration | |
b027f415 | 1111 | Specifies the configuration of Group, Summary, and Article |
745bc783 | 1112 | windows. It is a list of (ACTION (G S A)), where G, S, and A are |
b027f415 RS |
1113 | the relative height of Group, Summary, and Article windows, |
1114 | respectively. ACTION is `summary', `newsgroups', or `article'. | |
745bc783 JB |
1115 | |
1116 | gnus-subscribe-newsgroup-method | |
1117 | Specifies a function called with a newsgroup name when new | |
1118 | newsgroup is found. The default definition adds new newsgroup at | |
1119 | the beginning of other newsgroups. | |
1120 | ||
b027f415 RS |
1121 | And more and more. Please refer to texinfo documentation. |

b027f415 | 1124 | gnus-group-mode-hook |
745bc783 JB |
1125 | Entry to this mode calls the value with no arguments, if that |
1126 | value is non-nil. This hook is called before GNUS is connected to | |
1127 | the NNTP server. So, you can change or define the NNTP server in | |
1128 | this hook. | |
1129 | ||
b027f415 | 1130 | gnus-startup-hook |
745bc783 JB |
1131 | Called with no arguments after the NNTP server is selected. It is |
1132 | possible to change the behavior of GNUS or initialize the | |
1133 | variables according to the selected NNTP server. | |
1134 | ||
b027f415 | 1135 | gnus-group-prepare-hook |
745bc783 JB |
1136 | Called with no arguments after a newsgroup list is created in the |
1137 | Newsgroup buffer, if that value is non-nil. | |
1138 | ||
b027f415 | 1139 | gnus-save-newsrc-hook |
745bc783 JB |
1140 | Called with no arguments when saving newsrc file if that value is |
1141 | non-nil. | |
1142 | ||
b027f415 RS |
1143 | gnus-prepare-article-hook |
1144 | Called with no arguments after preparing message body, but before | |
1145 | preparing header fields which is automatically generated if that | |
1146 | value is non-nil. The default hook (gnus-inews-insert-signature) | |
1147 | inserts a signature file. | |
1148 | ||
1149 | gnus-inews-article-hook | |
745bc783 | 1150 | Called with no arguments when posting an article if that value is |
b027f415 RS |
1151 | non-nil. This hook is called just before posting an article. The |
1152 | default hook does FCC (save an article to the specified file). | |
745bc783 | 1153 | |
b027f415 | 1154 | gnus-suspend-gnus-hook |
745bc783 JB |
1155 | Called with no arguments when suspending (not exiting) GNUS, if |
1156 | that value is non-nil. | |
1157 | ||
b027f415 | 1158 | gnus-exit-gnus-hook |

4448 | In addition to Emacs-Lisp Mode, the following commands are available: | |
4449 | ||
b027f415 RS |
4450 | \\[gnus-kill-file-kill-by-subject] Insert KILL command for current subject. |
4451 | \\[gnus-kill-file-kill-by-author] Insert KILL command for current author. | |

4455 | \\[gnus-info-find-node] Read Info about KILL file. | |
745bc783 JB |
4456 | |
4457 | A KILL file contains lisp expressions to be applied to a selected | |
4458 | newsgroup. The purpose is to mark articles as read on the basis of | |
4459 | some set of regexps. A global KILL file is applied to every newsgroup, | |
4460 | and a local KILL file is applied to a specified newsgroup. Since a | |
4461 | global KILL file is applied to every newsgroup, for better performance | |
4462 | use a local one. | |
4463 | ||
4464 | A KILL file can contain any kind of Emacs lisp expressions expected | |
b027f415 | 4465 | to be evaluated in the Summary buffer. Writing lisp programs for this |
745bc783 JB |
4466 | purpose is not so easy because the internal working of GNUS must be |
4467 | well-known. For this reason, GNUS provides a general function which | |
4468 | does this easily for non-Lisp programmers. | |
4469 | ||
b027f415 | 4470 | The `gnus-kill' function executes commands available in Summary Mode |
745bc783 JB |
4471 | by their key sequences. `gnus-kill' should be called with FIELD, |
4472 | REGEXP and optional COMMAND and ALL. FIELD is a string representing | |
4473 | the header field or an empty string. If FIELD is an empty string, the | |
4474 | entire article body is searched for. REGEXP is a string which is | |
4475 | compared with FIELD value. COMMAND is a string representing a valid | |
b027f415 RS |
4476 | key sequence in Summary Mode or Lisp expression. COMMAND is default to |
4477 | '(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is | |
4478 | executed in the Summary buffer. If the second optional argument ALL | |
745bc783 JB |
4479 | is non-nil, the COMMAND is applied to articles which are already |
4480 | marked as read or unread. Articles which are marked are skipped over | |
4481 | by default. | |
4482 | ||
4483 | For example, if you want to mark articles of which subjects contain | |
4484 | the string `AI' as read, a possible KILL file may look like: | |
4485 | ||
4486 | (gnus-kill \"Subject\" \"AI\") | |
4487 | ||
4488 | If you want to mark articles with `D' instead of `X', you can use | |
4489 | the following expression: | |
4490 | ||
4491 | (gnus-kill \"Subject\" \"AI\" \"d\") | |
4492 | ||
4493 | In this example it is assumed that the command | |
b027f415 | 4494 | `gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode. |
745bc783 JB |
4495 | |
4496 | It is possible to delete unnecessary headers which are marked with | |
4497 | `X' in a KILL file as follows: | |
4498 | ||
4499 | (gnus-expunge \"X\") | |
4500 | ||
b027f415 | 4501 | If the Summary buffer is empty after applying KILL files, GNUS will |
745bc783 JB |
4502 | exit the selected newsgroup normally. If headers which are marked |
4503 | with `D' are deleted in a KILL file, it is impossible to read articles | |
4504 | which are marked as read in the previous GNUS sessions. Marks other | |
4505 | than `D' should be used for articles which should really be deleted. | |
