26 ;;; Commentary:
28 ;; GNUS Mailing List:
29 ;; There are two mailing lists for GNUS lovers in the world:
30 ;;
31 ;; info-gnus@flab.fujitsu.co.jp, and
32 ;; info-gnus-english@tut.cis.ohio-state.edu.
33 ;;
34 ;; They are intended to exchange useful information about GNUS, such
35 ;; as bug fixes, useful hooks, and extensions. The major difference
36 ;; between the lists is what the official language is. Both Japanese
37 ;; and English are available in info-gnus, while English is only
38 ;; available in info-gnus-english. There is no need to subscribe to
39 ;; info-gnus if you cannot read Japanese messages, because most of the
40 ;; discussion and important announcements will be sent to
41 ;; info-gnus-english. Moreover, if you can read gnu.emacs.gnus
42 ;; newsgroup of USENET, you need not, either. info-gnus-english and
43 ;; gnu.emacs.gnus are linked each other.
44 ;;
45 ;; Please send subscription request to:
46 ;;
47 ;; info-gnus-request@flab.fujitsu.co.jp, or
48 ;; info-gnus-english-request@cis.ohio-state.edu
50 ;; TO DO:
51 ;; (1) Incremental update of active info.
52 ;; (2) GNUS own poster.

798 host is specified. It is also possible to choose another NNTP server
799 even when the default server is defined by giving a prefix argument to
802 If an NNTP server is preceded by a colon such as `:Mail', the user's
803 private directory `~/Mail' is used as a news spool. This makes it
804 possible to read mail stored in MH folders or articles saved by GNUS.
805 File names of mail or articles must consist of only numeric
806 characters. Otherwise, they are ignored.
808 If there is a file named `~/.newsrc-SERVER', it is used as the
809 startup file instead of standard one when talking to SERVER. It is
810 possible to talk to many hosts by using different startup files for
811 each.
813 Option `-n' of the options line in the startup file is recognized
814 properly the same as the Bnews system. For example, if the options
815 line is `options -n !talk talk.rumors', newsgroups under the `talk'
816 hierarchy except for `talk.rumors' are ignored while checking new
817 newsgroups.
819 If there is a file named `~/.signature-DISTRIBUTION', it is used as
820 signature file instead of standard one when posting a news in

831 User customizable variables:
832 gnus-nntp-server
833 Specifies the name of the host running the NNTP server. If its
834 value is a string such as `:DIRECTORY', the user's private
835 DIRECTORY is used as a news spool. If its value is `::', then
836 the local news spool on the current machine is used directly.
837 The `NNTPSERVER' environment variable specifies the initial value
838 for this variable.
840 gnus-nntp-service
843 gnus-startup-file
844 Specifies a startup file (.newsrc). If there is a file named
845 `.newsrc-SERVER', it's used instead when talking to SERVER. I
846 recommend you to use the server specific file, if you'd like to
847 talk to many servers. Especially if you'd like to read your
848 private directory, the name of the file must be
849 `.newsrc-:DIRECTORY'.
851 gnus-signature-file
852 Specifies a signature file (.signature). If there is a file named
853 `.signature-DISTRIBUTION', it's used instead when posting an
854 article in DISTRIBUTION. Set the variable to nil to prevent
855 appending the file automatically. If you use an NNTP inews which
856 comes with the NNTP package, you may have to set the variable to
857 nil.
859 gnus-use-cross-reference
860 Specifies what to do with cross references (Xref: field). If it
861 is nil, cross references are ignored. If it is t, articles in
862 subscribed newsgroups are only marked as read. Otherwise, if it
863 is not nil nor t, articles in all newsgroups are marked as read.
865 gnus-use-followup-to
866 Specifies what to do with followup-to: field. If it is nil, its
867 value is ignored. If it is non-nil, its value is used as followup
868 newsgroups. Especially, if it is t and field value is `poster',
869 your confirmation is required.
871 gnus-author-copy
872 Specifies a file name to save a copy of article you posted using
873 FCC: field. If the first character of the value is `|', the
874 contents of the article is piped out to a program specified by the
875 rest of the value. The variable is initialized from the
876 AUTHORCOPY environment variable.
878 gnus-author-copy-saver
879 Specifies a function to save an author copy. The function is
880 called with a file name. The default function `rmail-output'
881 saves in Unix mail format.
883 gnus-kill-file-name
884 Use specified file name as a KILL file (default to `KILL').
886 gnus-novice-user
887 Non-nil means that you are a novice to USENET. If non-nil,
888 verbose messages may be displayed or your confirmations may be
889 required.
891 gnus-interactive-post
892 Non-nil means that newsgroup, subject and distribution are asked
893 for interactively when posting a new article.
895 gnus-use-full-window
896 Non-nil means to take up the entire screen of Emacs.
898 gnus-window-configuration
899 Specifies the configuration of Group, Subject, and Article
900 windows. It is a list of (ACTION (G S A)), where G, S, and A are
901 the relative height of Group, Subject, and Article windows,
902 respectively. ACTION is `SelectNewsgroup', `ExitNewsgroup',
903 `SelectArticle', or `ExpandSubject'.
905 gnus-subscribe-newsgroup-method
906 Specifies a function called with a newsgroup name when new
907 newsgroup is found. The default definition adds new newsgroup at
908 the beginning of other newsgroups.
910 Various hooks for customization:
911 gnus-Group-mode-hook
912 Entry to this mode calls the value with no arguments, if that
913 value is non-nil. This hook is called before GNUS is connected to
914 the NNTP server. So, you can change or define the NNTP server in
915 this hook.
917 gnus-Startup-hook
918 Called with no arguments after the NNTP server is selected. It is
919 possible to change the behavior of GNUS or initialize the
920 variables according to the selected NNTP server.
922 gnus-Group-prepare-hook
923 Called with no arguments after a newsgroup list is created in the
924 Newsgroup buffer, if that value is non-nil.
926 gnus-Save-newsrc-hook
927 Called with no arguments when saving newsrc file if that value is
928 non-nil.
930 gnus-Inews-article-hook
931 Called with no arguments when posting an article if that value is
932 non-nil. This hook is called just before posting an article, while
933 `news-inews-hook' is called before preparing article headers. If
934 you'd like to convert kanji code of the article, this hook is recommended.
936 gnus-Suspend-gnus-hook
937 Called with no arguments when suspending (not exiting) GNUS, if
938 that value is non-nil.
940 gnus-Exit-gnus-hook
941 Called with no arguments when exiting (not suspending) GNUS, if
942 that value is non-nil."

1565 as nntp-header-FIELD, and functions are defined as `gnus-header-FIELD'.
1567 gnus-article-save-directory
1568 Specifies a directory name to save articles to using the commands
1569 `gnus-Subject-save-in-rmail', `gnus-Subject-save-in-mail' and

1599 Specifies a function which generates an optional string displayed
1600 in the Subject buffer. The function is called with an article
1601 HEADERS. The result must be a string excluding `[' and `]'. The
1602 default function returns a string like NNN:AUTHOR, where NNN is
1603 the number of lines in an article and AUTHOR is the name of the
1604 author.
1606 gnus-auto-extend-newsgroup
1607 Non-nil means visible articles are extended to forward and

1659 available for the value of gnus-mail-reply-method. And functions
1660 gnus-mail-other-window-using-mail and
1661 gnus-mail-other-window-using-mhe are available for the value of
1662 gnus-mail-other-window-method.
1664 Various hooks for customization:
1665 gnus-Subject-mode-hook
1666 Entry to this mode calls the value with no arguments, if that
1667 value is non-nil.
1669 gnus-Select-group-hook
1670 Called with no arguments when newsgroup is selected, if that value
1671 is non-nil. It is possible to sort subjects in this hook. See the
1672 documentation of this variable for more information.
1674 gnus-Subject-prepare-hook
1675 Called with no arguments after a subject list is created in the
1676 Subject buffer, if that value is non-nil. If you'd like to modify
1677 the buffer, you can use this hook.
1679 gnus-Select-article-hook
1680 Called with no arguments when an article is selected, if that
1681 value is non-nil. See the documentation of this variable for
1682 more information.
1684 gnus-Select-digest-hook
1685 Called with no arguments when reading digest messages using Rmail,
1686 if that value is non-nil. This hook can be used to modify an
1687 article so that Rmail can work with it. See the documentation of
1688 the variable for more information.
1690 gnus-Rmail-digest-hook
1691 Called with no arguments when reading digest messages using Rmail,
1692 if that value is non-nil. This hook is intended to customize Rmail
1693 mode.
1695 gnus-Apply-kill-hook
1696 Called with no arguments when a newsgroup is selected and the
1697 Subject buffer is prepared. This hook is intended to apply a KILL
1698 file to the selected newsgroup. The format of KILL file is
1699 completely different from that of version 3.8. You have to rewrite
1700 them in the new format. See the documentation of Kill file mode
1701 for more information.
1703 gnus-Mark-article-hook
1704 Called with no arguments when an article is selected at the first
1705 time. The hook is intended to mark an article as read (or unread)
1706 automatically when it is selected. See the documentation of the
1707 variable for more information.
1709 gnus-Exit-group-hook
1710 Called with no arguments when exiting the current newsgroup, if
1711 that value is non-nil. If your machine is so slow that exiting
1712 from Subject mode takes very long time, inhibit marking articles
1713 as read using cross-references by setting the variable
1714 `gnus-newsgroup-headers' to nil in this hook."

3935 "Major mode for editing KILL file.
3937 In addition to Emacs-Lisp Mode, the following commands are available:
3946 A KILL file contains lisp expressions to be applied to a selected
3947 newsgroup. The purpose is to mark articles as read on the basis of
3948 some set of regexps. A global KILL file is applied to every newsgroup,
3949 and a local KILL file is applied to a specified newsgroup. Since a
3950 global KILL file is applied to every newsgroup, for better performance
3951 use a local one.
3953 A KILL file can contain any kind of Emacs lisp expressions expected
3954 to be evaluated in the Subject buffer. Writing lisp programs for this
3955 purpose is not so easy because the internal working of GNUS must be
3956 well-known. For this reason, GNUS provides a general function which
3957 does this easily for non-Lisp programmers.
3959 The `gnus-kill' function executes commands available in Subject Mode
3960 by their key sequences. `gnus-kill' should be called with FIELD,
3961 REGEXP and optional COMMAND and ALL. FIELD is a string representing
3962 the header field or an empty string. If FIELD is an empty string, the
3963 entire article body is searched for. REGEXP is a string which is
3964 compared with FIELD value. COMMAND is a string representing a valid
3965 key sequence in Subject Mode or Lisp expression. COMMAND is default to
3967 executed in the Subject buffer. If the second optional argument ALL
3968 is non-nil, the COMMAND is applied to articles which are already
3969 marked as read or unread. Articles which are marked are skipped over
3970 by default.
3972 For example, if you want to mark articles of which subjects contain
3973 the string `AI' as read, a possible KILL file may look like:
3977 If you want to mark articles with `D' instead of `X', you can use
3978 the following expression:
3982 In this example it is assumed that the command
3983 `gnus-Subject-mark-as-read-forward' is assigned to `d' in Subject Mode.
3985 It is possible to delete unnecessary headers which are marked with
3986 `X' in a KILL file as follows:
3990 If the Subject buffer is empty after applying KILL files, GNUS will
3991 exit the selected newsgroup normally. If headers which are marked
3992 with `D' are deleted in a KILL file, it is impossible to read articles
3993 which are marked as read in the previous GNUS sessions. Marks other
3994 than `D' should be used for articles which should really be deleted.
3996 Entry to this mode calls emacs-lisp-mode-hook and
3997 gnus-Kill-file-mode-hook with no arguments, if that value is non-nil."
