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

45 ;; info-gnus-request@flab.fujitsu.co.jp, or
46 ;; info-gnus-english-request@cis.ohio-state.edu

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

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

1562 and optional LAST-FILE. Access macros to the headers are defined
1563 as nntp-header-FIELD, and functions are defined as `gnus-header-FIELD'.
1565 gnus-article-save-directory
1566 Specifies a directory name to save articles to using the commands
1567 `gnus-Subject-save-in-rmail', `gnus-Subject-save-in-mail' and

1594 Indentation of thread subtrees.
1596 gnus-optional-headers
1597 Specifies a function which generates an optional string displayed
1598 in the Subject buffer. The function is called with an article
1599 HEADERS. The result must be a string excluding `[' and `]'. The
1600 default function returns a string like NNN:AUTHOR, where NNN is
1601 the number of lines in an article and AUTHOR is the name of the
1602 author.
1604 gnus-auto-extend-newsgroup
1605 Non-nil means visible articles are extended to forward and
1606 backward automatically if possible.
1608 gnus-auto-select-first
1609 Non-nil means the first unread article is selected automagically
1610 when a newsgroup is selected normally (by gnus-Group-read-group).
1611 If you'd like to prevent automatic selection of the first unread

1615 gnus-auto-select-next
1616 Non-nil means the next newsgroup is selected automagically at the
1617 end of the newsgroup. If the value is t and the next newsgroup is
1618 empty (no unread articles), GNUS will exit Subject mode and go
1619 back to Group mode. If the value is neither nil nor t, GNUS won't
1620 exit Subject mode but select the following unread newsgroup.
1621 Especially, if the value is the symbol `quietly', the next unread
1622 newsgroup will be selected without any confirmations.
1624 gnus-auto-select-same
1625 Non-nil means an article with the same subject as the current
1626 article is selected automagically like `rn -S'.

1656 gnus-mail-reply-using-mail and gnus-mail-reply-using-mhe are
1657 available for the value of gnus-mail-reply-method. And functions
1658 gnus-mail-other-window-using-mail and
1659 gnus-mail-other-window-using-mhe are available for the value of
1660 gnus-mail-other-window-method.
1662 Various hooks for customization:
1663 gnus-Subject-mode-hook
1664 Entry to this mode calls the value with no arguments, if that
1665 value is non-nil.
1667 gnus-Select-group-hook
1668 Called with no arguments when newsgroup is selected, if that value
1669 is non-nil. It is possible to sort subjects in this hook. See the
1670 documentation of this variable for more information.
1672 gnus-Subject-prepare-hook
1673 Called with no arguments after a subject list is created in the
1674 Subject buffer, if that value is non-nil. If you'd like to modify
1675 the buffer, you can use this hook.
1677 gnus-Select-article-hook
1678 Called with no arguments when an article is selected, if that
1679 value is non-nil. See the documentation of this variable for
1680 more information.
1682 gnus-Select-digest-hook
1683 Called with no arguments when reading digest messages using Rmail,
1684 if that value is non-nil. This hook can be used to modify an
1685 article so that Rmail can work with it. See the documentation of
1686 the variable for more information.
1688 gnus-Rmail-digest-hook
1689 Called with no arguments when reading digest messages using Rmail,
1690 if that value is non-nil. This hook is intended to customize Rmail
1691 mode.
1693 gnus-Apply-kill-hook
1694 Called with no arguments when a newsgroup is selected and the
1695 Subject buffer is prepared. This hook is intended to apply a KILL
1696 file to the selected newsgroup. The format of KILL file is
1697 completely different from that of version 3.8. You have to rewrite
1698 them in the new format. See the documentation of Kill file mode
1699 for more information.
1701 gnus-Mark-article-hook
1702 Called with no arguments when an article is selected at the first
1703 time. The hook is intended to mark an article as read (or unread)
1704 automatically when it is selected. See the documentation of the
1705 variable for more information.
1707 gnus-Exit-group-hook
1708 Called with no arguments when exiting the current newsgroup, if
1709 that value is non-nil. If your machine is so slow that exiting
1710 from Subject mode takes very long time, inhibit marking articles
1711 as read using cross-references by setting the variable
1712 `gnus-newsgroup-headers' to nil in this hook."

3933 "Major mode for editing KILL file.
3935 In addition to Emacs-Lisp Mode, the following commands are available:
3944 A KILL file contains lisp expressions to be applied to a selected
3945 newsgroup. The purpose is to mark articles as read on the basis of
3946 some set of regexps. A global KILL file is applied to every newsgroup,
3947 and a local KILL file is applied to a specified newsgroup. Since a
3948 global KILL file is applied to every newsgroup, for better performance
3949 use a local one.
3951 A KILL file can contain any kind of Emacs lisp expressions expected
3952 to be evaluated in the Subject buffer. Writing lisp programs for this
3953 purpose is not so easy because the internal working of GNUS must be
3954 well-known. For this reason, GNUS provides a general function which
3955 does this easily for non-Lisp programmers.
3957 The `gnus-kill' function executes commands available in Subject Mode
3958 by their key sequences. `gnus-kill' should be called with FIELD,
3959 REGEXP and optional COMMAND and ALL. FIELD is a string representing
3960 the header field or an empty string. If FIELD is an empty string, the
3961 entire article body is searched for. REGEXP is a string which is
3962 compared with FIELD value. COMMAND is a string representing a valid
3963 key sequence in Subject Mode or Lisp expression. COMMAND is default to
3965 executed in the Subject buffer. If the second optional argument ALL
3966 is non-nil, the COMMAND is applied to articles which are already
3967 marked as read or unread. Articles which are marked are skipped over
3968 by default.
3970 For example, if you want to mark articles of which subjects contain
3971 the string `AI' as read, a possible KILL file may look like:
3975 If you want to mark articles with `D' instead of `X', you can use
3976 the following expression:
3980 In this example it is assumed that the command
3981 `gnus-Subject-mark-as-read-forward' is assigned to `d' in Subject Mode.
3983 It is possible to delete unnecessary headers which are marked with
3984 `X' in a KILL file as follows:
3988 If the Subject buffer is empty after applying KILL files, GNUS will
3989 exit the selected newsgroup normally. If headers which are marked
3990 with `D' are deleted in a KILL file, it is impossible to read articles
3991 which are marked as read in the previous GNUS sessions. Marks other
3992 than `D' should be used for articles which should really be deleted.
3994 Entry to this mode calls emacs-lisp-mode-hook and
3995 gnus-Kill-file-mode-hook with no arguments, if that value is non-nil."
