| 24 | ;;; Commentary: |
| 25 | |
| 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. |
| 89 | |
| 90 | ;; TO DO: |
| 91 | ;; (1) Incremental update of active info. |
| 92 | ;; (2) Asynchronous transmission of large messages. |

| 1013 | The name of the host running NNTP server is asked for if no default |
| 1014 | host is specified. It is also possible to choose another NNTP server |
| 1015 | even when the default server is defined by giving a prefix argument to |
| 1016 | the command `\\[gnus]'. |
| 1017 | |
| 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. |
| 1023 | |
| 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. |
| 1028 | |
| 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. |
| 1034 | |
| 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. |
| 1038 | |
| 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 |
| 1041 | current major mode of GNUS by \\[gnus-info-find-node]. |
| 1042 | |
| 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. |
| 1046 | |
| 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. |
| 1053 | |
| 1054 | gnus-nntp-service |
| 1055 | Specifies a NNTP service name. It is usually \"nntp\" or 119. |
| 1056 | Nil forces GNUS to use a local news spool if the variable |
| 1057 | `gnus-nntp-server' is set to the local host name. |
| 1058 | |
| 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'. |
| 1066 | |
| 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. |
| 1074 | |
| 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. |
| 1080 | |
| 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. |
| 1086 | |
| 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. |
| 1093 | |
| 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. |
| 1098 | |
| 1099 | gnus-kill-file-name |
| 1100 | Use specified file name as a KILL file (default to `KILL'). |
| 1101 | |
| 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. |
| 1106 | |
| 1107 | gnus-interactive-post |
| 1108 | Non-nil means that newsgroup, subject and distribution are asked |
| 1109 | for interactively when posting a new article. |
| 1110 | |
| 1111 | gnus-use-full-window |
| 1112 | Non-nil means to take up the entire screen of Emacs. |
| 1113 | |
| 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'. |
| 1119 | |
| 1120 | gnus-subscribe-newsgroup-method |
| 1121 | Specifies a function called with a newsgroup name when new |
| 1122 | newsgroup is found. The default definition adds new newsgroup at |
| 1123 | the beginning of other newsgroups. |
| 1124 | |
| 1125 | And more and more. Please refer to texinfo documentation. |
| 1126 | |
| 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. |
| 1133 | |
| 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. |
| 1138 | |
| 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. |
| 1142 | |
| 1143 | gnus-save-newsrc-hook |
| 1144 | Called with no arguments when saving newsrc file if that value is |
| 1145 | non-nil. |
| 1146 | |
| 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. |
| 1152 | |
| 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). |
| 1157 | |
| 1158 | gnus-suspend-gnus-hook |
| 1159 | Called with no arguments when suspending (not exiting) GNUS, if |
| 1160 | that value is non-nil. |
| 1161 | |
| 1162 | gnus-exit-gnus-hook |
| 1163 | Called with no arguments when exiting (not suspending) GNUS, if |

| 2026 | Functions gnus-mail-reply-using-mail and gnus-mail-reply-using-mhe |
| 2027 | are available for the value of gnus-mail-reply-method. And |
| 2028 | functions gnus-mail-other-window-using-mail and |
| 2029 | gnus-mail-other-window-using-mhe are available for the value of |
| 2030 | gnus-mail-other-window-method. |
| 2031 | |
| 2032 | gnus-mail-send-method |
| 2033 | Specifies a function to mail a message too which is being posted |
| 2034 | as an article. The message must have To: or Cc: field. The value |
| 2035 | of the variable send-mail-function is the default function which |
| 2036 | uses sendmail mail program. |

| 2038 | Various hooks for customization: |
| 2039 | gnus-summary-mode-hook |
| 2040 | Entry to this mode calls the value with no arguments, if that |
| 2041 | value is non-nil. |
| 2042 | |
| 2043 | gnus-select-group-hook |
| 2044 | Called with no arguments when newsgroup is selected, if that value |
| 2045 | is non-nil. It is possible to sort subjects in this hook. See the |
| 2046 | documentation of this variable for more information. |
| 2047 | |
| 2048 | gnus-summary-prepare-hook |
| 2049 | Called with no arguments after a summary list is created in the |
| 2050 | Summary buffer, if that value is non-nil. If you'd like to modify |
| 2051 | the buffer, you can use this hook. |
| 2052 | |
| 2053 | gnus-select-article-hook |
| 2054 | Called with no arguments when an article is selected, if that |
| 2055 | value is non-nil. See the documentation of this variable for more |
| 2056 | information. |
| 2057 | |
| 2058 | gnus-select-digest-hook |
| 2059 | Called with no arguments when reading digest messages using Rmail, |
| 2060 | if that value is non-nil. This hook can be used to modify an |
| 2061 | article so that Rmail can work with it. See the documentation of |
| 2062 | the variable for more information. |
| 2063 | |
| 2064 | gnus-rmail-digest-hook |
| 2065 | Called with no arguments when reading digest messages using Rmail, |
| 2066 | if that value is non-nil. This hook is intended to customize Rmail |
| 2067 | mode. |
| 2068 | |
| 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. |
| 2076 | |
| 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. |
| 2082 | |
| 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 |
| 2086 | from Summary mode takes very long time, inhibit marking articles |
| 2087 | as read using cross-references by setting the variable |
| 2088 | gnus-use-cross-reference to nil in this hook." |

| 4460 | |
| 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. |
| 4467 | |
| 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. |
| 4473 | |
| 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 |
| 4481 | '(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is |
| 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. |
| 4486 | |
| 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: |
| 4489 | |
| 4490 | (gnus-kill \"Subject\" \"AI\") |
| 4491 | |
| 4492 | If you want to mark articles with `D' instead of `X', you can use |
| 4493 | the following expression: |
| 4494 | |
| 4495 | (gnus-kill \"Subject\" \"AI\" \"d\") |
| 4496 | |
| 4497 | In this example it is assumed that the command |
| 4498 | `gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode. |
| 4499 | |
| 4500 | It is possible to delete unnecessary headers which are marked with |
| 4501 | `X' in a KILL file as follows: |
| 4502 | |
| 4503 | (gnus-expunge \"X\") |
| 4504 | |
| 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. |
