24 ;;; Commentary:
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.
86 ;;
87 ;; For getting more information about GNUS, consult USENET newsgorup
88 ;; gnu.emacs.gnus.
90 ;; TO DO:
91 ;; (1) Incremental update of active info.
92 ;; (2) Asynchronous transmission of large messages.
94 ;;; Code:
101 "*Specify default NNTP server.
105 "*The name of the host running NNTP server.
106 If it is a string such as `:DIRECTORY', the user's private DIRECTORY

140 Articles are saved using a function specified by the the variable
141 `gnus-author-copy-saver' (`rmail-output' is default) if a file name is
142 given. Instead, if the first character of the name is `|', the
143 contents of the article is piped out to the named program. It is
144 possible to save an article in an MH folder as follows:
149 "*A function called with a file name to save an author copy to.
154 "*Non-nil means that a newsgroup name is used as a default file name
155 to save articles to. If it's nil, the directory form of a newsgroup is

164 The function must be interactively callable (in other words, it must
165 be an Emacs command).
167 GNUS provides the following functions:

278 If the value is t and the next newsgroup is empty, GNUS will exit
279 Summary mode and go back to Group mode. If the value is neither nil

281 the value is the symbol `quietly', the next unread newsgroup will be

499 The function `gnus-apply-kill-file' is called by default.
501 Since a general KILL file is too heavy to use only for a few
502 newsgroups, I recommend you to use a lighter hook function. For
503 example, if you'd like to apply a KILL file to articles which contains

1013 The name of the host running NNTP server is asked for if no default

1015 even when the default server is defined by giving a prefix argument to
1018 If an NNTP server is preceded by a colon such as `:Mail', the user's
1019 private directory `~/Mail' is used as a news spool. This makes it
1020 possible to read mail stored in MH folders or articles saved by GNUS.
1021 File names of mail or articles must consist of only numeric
1022 characters. Otherwise, they are ignored.
1024 If there is a file named `~/.newsrc-SERVER', it is used as the
1025 startup file instead of standard one when talking to SERVER. It is
1026 possible to talk to many hosts by using different startup files for
1027 each.
1029 Option `-n' of the options line in the startup file is recognized
1030 properly the same as the Bnews system. For example, if the options
1031 line is `options -n !talk talk.rumors', newsgroups under the `talk'
1032 hierarchy except for `talk.rumors' are ignored while checking new
1033 newsgroups.
1035 If there is a file named `~/.signature-DISTRIBUTION', it is used as
1036 signature file instead of standard one when posting a news in
1037 DISTRIBUTION.
1039 If an Info file generated from `gnus.texinfo' is installed, you can
1040 read an appropriate Info node of the Info file according to the
1043 The variable `gnus-version', `nntp-version', `nnspool-version', and
1044 `mhspool-version' have the version numbers of this version of gnus.el,
1045 nntp.el, nnspool.el, and mhspoo.el, respectively.
1047 User customizable variables:
1048 gnus-nntp-server
1049 Specifies the name of the host running the NNTP server. If its
1050 value is a string such as `:DIRECTORY', the user's private
1051 DIRECTORY is used as a news spool. The variable is initialized
1052 from the NNTPSERVER environment variable.
1054 gnus-nntp-service
1056 Nil forces GNUS to use a local news spool if the variable
1057 `gnus-nntp-server' is set to the local host name.
1059 gnus-startup-file
1060 Specifies a startup file (.newsrc). If there is a file named
1061 `.newsrc-SERVER', it's used instead when talking to SERVER. I
1062 recommend you to use the server specific file, if you'd like to
1063 talk to many servers. Especially if you'd like to read your
1064 private directory, the name of the file must be
1065 `.newsrc-:DIRECTORY'.
1067 gnus-signature-file
1068 Specifies a signature file (.signature). If there is a file named
1069 `.signature-DISTRIBUTION', it's used instead when posting an
1070 article in DISTRIBUTION. Set the variable to nil to prevent
1071 appending the file automatically. If you use an NNTP inews which
1072 comes with the NNTP package, you may have to set the variable to
1073 nil.
1075 gnus-use-cross-reference
1076 Specifies what to do with cross references (Xref: field). If it
1077 is nil, cross references are ignored. If it is t, articles in
1078 subscribed newsgroups are only marked as read. Otherwise, if it
1079 is not nil nor t, articles in all newsgroups are marked as read.
1081 gnus-use-followup-to
1082 Specifies what to do with followup-to: field. If it is nil, its
1083 value is ignored. If it is non-nil, its value is used as followup
1084 newsgroups. Especially, if it is t and field value is `poster',
1085 your confirmation is required.
1087 gnus-author-copy
1088 Specifies a file name to save a copy of article you posted using
1089 FCC: field. If the first character of the value is `|', the
1090 contents of the article is piped out to a program specified by the
1091 rest of the value. The variable is initialized from the
1092 AUTHORCOPY environment variable.
1094 gnus-author-copy-saver
1095 Specifies a function to save an author copy. The function is
1096 called with a file name. The default function `rmail-output'
1097 saves in Unix mail format.
1099 gnus-kill-file-name
1100 Use specified file name as a KILL file (default to `KILL').
1102 gnus-novice-user
1103 Non-nil means that you are a novice to USENET. If non-nil,
1104 verbose messages may be displayed or your confirmations may be
1105 required.
1107 gnus-interactive-post
1108 Non-nil means that newsgroup, subject and distribution are asked
1109 for interactively when posting a new article.
1111 gnus-use-full-window
1112 Non-nil means to take up the entire screen of Emacs.
1114 gnus-window-configuration
1115 Specifies the configuration of Group, Summary, and Article
1116 windows. It is a list of (ACTION (G S A)), where G, S, and A are
1117 the relative height of Group, Summary, and Article windows,
1118 respectively. ACTION is `summary', `newsgroups', or `article'.
1120 gnus-subscribe-newsgroup-method
1121 Specifies a function called with a newsgroup name when new

1127 Various hooks for customization:
1128 gnus-group-mode-hook
1129 Entry to this mode calls the value with no arguments, if that
1130 value is non-nil. This hook is called before GNUS is connected to
1131 the NNTP server. So, you can change or define the NNTP server in
1132 this hook.
1134 gnus-startup-hook
1135 Called with no arguments after the NNTP server is selected. It is
1136 possible to change the behavior of GNUS or initialize the
1137 variables according to the selected NNTP server.
1139 gnus-group-prepare-hook
1140 Called with no arguments after a newsgroup list is created in the
1141 Newsgroup buffer, if that value is non-nil.
1143 gnus-save-newsrc-hook
1144 Called with no arguments when saving newsrc file if that value is
1145 non-nil.
1147 gnus-prepare-article-hook
1148 Called with no arguments after preparing message body, but before
1149 preparing header fields which is automatically generated if that
1150 value is non-nil. The default hook (gnus-inews-insert-signature)
1151 inserts a signature file.
1153 gnus-inews-article-hook
1154 Called with no arguments when posting an article if that value is
1155 non-nil. This hook is called just before posting an article. The
1156 default hook does FCC (save an article to the specified file).
1158 gnus-suspend-gnus-hook
1159 Called with no arguments when suspending (not exiting) GNUS, if
1160 that value is non-nil.
1162 gnus-exit-gnus-hook
1163 Called with no arguments when exiting (not suspending) GNUS, if
1164 that value is non-nil."

2067 mode.
2069 gnus-apply-kill-hook
2070 Called with no arguments when a newsgroup is selected and the
2071 Summary buffer is prepared. This hook is intended to apply a KILL
2072 file to the selected newsgroup. The format of KILL file is
2073 completely different from that of version 3.8. You have to rewrite
2074 them in the new format. See the documentation of Kill file mode
2075 for more information.
2077 gnus-mark-article-hook
2078 Called with no arguments when an article is selected at the first
2079 time. The hook is intended to mark an article as read (or unread)
2080 automatically when it is selected. See the documentation of the
2081 variable for more information.
2083 gnus-exit-group-hook
2084 Called with no arguments when exiting the current newsgroup, if
2085 that value is non-nil. If your machine is so slow that exiting

4450 "Major mode for editing KILL file.
4452 In addition to Emacs-Lisp Mode, the following commands are available:
4461 A KILL file contains lisp expressions to be applied to a selected
4462 newsgroup. The purpose is to mark articles as read on the basis of
4463 some set of regexps. A global KILL file is applied to every newsgroup,
4464 and a local KILL file is applied to a specified newsgroup. Since a
4465 global KILL file is applied to every newsgroup, for better performance
4466 use a local one.
4468 A KILL file can contain any kind of Emacs lisp expressions expected
4469 to be evaluated in the Summary buffer. Writing lisp programs for this
4470 purpose is not so easy because the internal working of GNUS must be
4471 well-known. For this reason, GNUS provides a general function which
4472 does this easily for non-Lisp programmers.
4474 The `gnus-kill' function executes commands available in Summary Mode
4475 by their key sequences. `gnus-kill' should be called with FIELD,
4476 REGEXP and optional COMMAND and ALL. FIELD is a string representing
4477 the header field or an empty string. If FIELD is an empty string, the
4478 entire article body is searched for. REGEXP is a string which is
4479 compared with FIELD value. COMMAND is a string representing a valid
4480 key sequence in Summary Mode or Lisp expression. COMMAND is default to
4482 executed in the Summary buffer. If the second optional argument ALL
4483 is non-nil, the COMMAND is applied to articles which are already
4484 marked as read or unread. Articles which are marked are skipped over
4485 by default.
4487 For example, if you want to mark articles of which subjects contain
4488 the string `AI' as read, a possible KILL file may look like:
4492 If you want to mark articles with `D' instead of `X', you can use
4493 the following expression:
4497 In this example it is assumed that the command
4498 `gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
4500 It is possible to delete unnecessary headers which are marked with
4501 `X' in a KILL file as follows:
4505 If the Summary buffer is empty after applying KILL files, GNUS will
4506 exit the selected newsgroup normally. If headers which are marked
4507 with `D' are deleted in a KILL file, it is impossible to read articles
4508 which are marked as read in the previous GNUS sessions. Marks other
4509 than `D' should be used for articles which should really be deleted.
4511 Entry to this mode calls emacs-lisp-mode-hook and
4512 gnus-kill-file-mode-hook with no arguments, if that value is non-nil."
