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

786 The name of the host running NNTP server is asked for if no default
787 host is specified. It is also possible to choose another NNTP server
788 even when the default server is defined by giving a prefix argument to
791 If an NNTP server is preceded by a colon such as `:Mail', the user's
792 private directory `~/Mail' is used as a news spool. This makes it
793 possible to read mail stored in MH folders or articles saved by GNUS.
794 File names of mail or articles must consist of only numeric
795 characters. Otherwise, they are ignored.
797 If there is a file named `~/.newsrc-SERVER', it is used as the
798 startup file instead of standard one when talking to SERVER. It is
799 possible to talk to many hosts by using different startup files for
800 each.
802 Option `-n' of the options line in the startup file is recognized
803 properly the same as the Bnews system. For example, if the options
804 line is `options -n !talk talk.rumors', newsgroups under the `talk'
805 hierarchy except for `talk.rumors' are ignored while checking new
806 newsgroups.
808 If there is a file named `~/.signature-DISTRIBUTION', it is used as
809 signature file instead of standard one when posting a news in
810 DISTRIBUTION.

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

1544 gnus-Subject-save-in-folder (in MH folder)
1545 gnus-Subject-save-in-file (in article format).
1547 gnus-rmail-save-name
1548 gnus-mail-save-name
1549 gnus-folder-save-name
1550 gnus-file-save-name
1551 Specifies a function generating a file name to save articles in
1552 specified format. The function is called with NEWSGROUP, HEADERS,
1553 and optional LAST-FILE. Access macros to the headers are defined
1554 as nntp-header-FIELD, and functions are defined as `gnus-header-FIELD'.
1556 gnus-article-save-directory
1557 Specifies a directory name to save articles to using the commands
1558 `gnus-Subject-save-in-rmail', `gnus-Subject-save-in-mail' and

1585 Indentation of thread subtrees.
1587 gnus-optional-headers
1588 Specifies a function which generates an optional string displayed
1589 in the Subject buffer. The function is called with an article
1590 HEADERS. The result must be a string excluding `[' and `]'. The
1591 default function returns a string like NNN:AUTHOR, where NNN is
1592 the number of lines in an article and AUTHOR is the name of the
1593 author.
1595 gnus-auto-extend-newsgroup
1596 Non-nil means visible articles are extended to forward and
1597 backward automatically if possible.
1599 gnus-auto-select-first
1600 Non-nil means the first unread article is selected automagically
1601 when a newsgroup is selected normally (by gnus-Group-read-group).
1602 If you'd like to prevent automatic selection of the first unread

1604 gnus-Select-group-hook or gnus-Apply-kill-hook.
1606 gnus-auto-select-next
1607 Non-nil means the next newsgroup is selected automagically at the
1608 end of the newsgroup. If the value is t and the next newsgroup is
1609 empty (no unread articles), GNUS will exit Subject mode and go
1610 back to Group mode. If the value is neither nil nor t, GNUS won't
1611 exit Subject mode but select the following unread newsgroup.
1612 Especially, if the value is the symbol `quietly', the next unread
1613 newsgroup will be selected without any confirmations.
1615 gnus-auto-select-same
1616 Non-nil means an article with the same subject as the current
1617 article is selected automagically like `rn -S'.

1647 gnus-mail-reply-using-mail and gnus-mail-reply-using-mhe are
1648 available for the value of gnus-mail-reply-method. And functions
1649 gnus-mail-other-window-using-mail and
1650 gnus-mail-other-window-using-mhe are available for the value of
1651 gnus-mail-other-window-method.
1653 Various hooks for customization:
1654 gnus-Subject-mode-hook
1655 Entry to this mode calls the value with no arguments, if that
1656 value is non-nil.
1658 gnus-Select-group-hook
1659 Called with no arguments when newsgroup is selected, if that value
1660 is non-nil. It is possible to sort subjects in this hook. See the
1661 documentation of this variable for more information.
1663 gnus-Subject-prepare-hook
1664 Called with no arguments after a subject list is created in the
1665 Subject buffer, if that value is non-nil. If you'd like to modify
1666 the buffer, you can use this hook.
1668 gnus-Select-article-hook
1669 Called with no arguments when an article is selected, if that
1670 value is non-nil. See the documentation of this variable for
1671 more information.
1673 gnus-Select-digest-hook
1674 Called with no arguments when reading digest messages using Rmail,
1675 if that value is non-nil. This hook can be used to modify an
1676 article so that Rmail can work with it. See the documentation of
1677 the variable for more information.
1679 gnus-Rmail-digest-hook
1680 Called with no arguments when reading digest messages using Rmail,
1681 if that value is non-nil. This hook is intended to customize Rmail
1682 mode.
1684 gnus-Apply-kill-hook
1685 Called with no arguments when a newsgroup is selected and the
1686 Subject buffer is prepared. This hook is intended to apply a KILL
1687 file to the selected newsgroup. The format of KILL file is
1688 completely different from that of version 3.8. You have to rewrite
1689 them in the new format. See the documentation of Kill file mode
1690 for more information.
1692 gnus-Mark-article-hook
1693 Called with no arguments when an article is selected at the first
1694 time. The hook is intended to mark an article as read (or unread)
1695 automatically when it is selected. See the documentation of the
1696 variable for more information.
1698 gnus-Exit-group-hook
1699 Called with no arguments when exiting the current newsgroup, if
1700 that value is non-nil. If your machine is so slow that exiting
1701 from Subject mode takes very long time, inhibit marking articles
1702 as read using cross-references by setting the variable
1703 `gnus-newsgroup-headers' to nil in this hook."

3924 "Major mode for editing KILL file.
3926 In addition to Emacs-Lisp Mode, the following commands are available:
3935 A KILL file contains lisp expressions to be applied to a selected
3936 newsgroup. The purpose is to mark articles as read on the basis of
3937 some set of regexps. A global KILL file is applied to every newsgroup,
3938 and a local KILL file is applied to a specified newsgroup. Since a
3939 global KILL file is applied to every newsgroup, for better performance
3940 use a local one.
3942 A KILL file can contain any kind of Emacs lisp expressions expected
3943 to be evaluated in the Subject buffer. Writing lisp programs for this
3944 purpose is not so easy because the internal working of GNUS must be
3945 well-known. For this reason, GNUS provides a general function which
3946 does this easily for non-Lisp programmers.
3948 The `gnus-kill' function executes commands available in Subject Mode
3949 by their key sequences. `gnus-kill' should be called with FIELD,
3950 REGEXP and optional COMMAND and ALL. FIELD is a string representing
3951 the header field or an empty string. If FIELD is an empty string, the
3952 entire article body is searched for. REGEXP is a string which is
3953 compared with FIELD value. COMMAND is a string representing a valid
3954 key sequence in Subject Mode or Lisp expression. COMMAND is default to
3956 executed in the Subject buffer. If the second optional argument ALL
3957 is non-nil, the COMMAND is applied to articles which are already
3958 marked as read or unread. Articles which are marked are skipped over
3959 by default.
3961 For example, if you want to mark articles of which subjects contain
3962 the string `AI' as read, a possible KILL file may look like:
3966 If you want to mark articles with `D' instead of `X', you can use
3967 the following expression:
3971 In this example it is assumed that the command
3972 `gnus-Subject-mark-as-read-forward' is assigned to `d' in Subject Mode.
3974 It is possible to delete unnecessary headers which are marked with
3975 `X' in a KILL file as follows:
3979 If the Subject buffer is empty after applying KILL files, GNUS will
3980 exit the selected newsgroup normally. If headers which are marked
3981 with `D' are deleted in a KILL file, it is impossible to read articles
3982 which are marked as read in the previous GNUS sessions. Marks other
3983 than `D' should be used for articles which should really be deleted.
