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: | |
44 | ;; | |
45 | ;; info-gnus-request@flab.fujitsu.co.jp, or | |
46 | ;; info-gnus-english-request@cis.ohio-state.edu | |
47 | ||
48 | ;; TO DO: | |
49 | ;; (1) Incremental update of active info. | |
50 | ;; (2) GNUS own poster. | |
51 | ;; (3) Multi-GNUS (Talking to many hosts same time). | |
52 | ;; (4) Asynchronous transmission of large messages. | |

794 | ||
795 | The name of the host running NNTP server is asked for if no default | |
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 | |
798 | the command `\\[gnus]'. | |
799 | ||
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. | |
805 | ||
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. | |
810 | ||
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. | |
816 | ||
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. | |
820 | ||
821 | If an Info file generated from `gnus.texinfo' is installed, you can | |
822 | read an appropriate Info node of the Info file according to the | |
823 | current major mode of GNUS by \\[gnus-Info-find-node]. | |
824 | ||
825 | The variable `gnus-version', `nntp-version', `nnspool-version', and | |

827 | nntp.el, nnspool.el, and mhspoo.el, respectively. | |
828 | ||
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 | |
343fbb30 RS |
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. | |
745bc783 JB |
837 | |
838 | gnus-nntp-service | |
343fbb30 | 839 | Specifies a NNTP service name. It is usually \"nntp\". |
745bc783 JB |
840 | |
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'. | |
848 | ||
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. | |
856 | ||
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. | |
862 | ||
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. | |
868 | ||
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. | |
875 | ||
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. | |
880 | ||
881 | gnus-kill-file-name | |
882 | Use specified file name as a KILL file (default to `KILL'). | |
883 | ||
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. | |
888 | ||
889 | gnus-interactive-post | |
890 | Non-nil means that newsgroup, subject and distribution are asked | |
891 | for interactively when posting a new article. | |
892 | ||
893 | gnus-use-full-window | |
894 | Non-nil means to take up the entire screen of Emacs. | |
895 | ||
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'. | |
902 | ||
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. | |
907 | ||
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. | |
914 | ||
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. | |
919 | ||
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. | |
923 | ||
924 | gnus-Save-newsrc-hook | |
925 | Called with no arguments when saving newsrc file if that value is | |
926 | non-nil. | |
927 | ||
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. | |
933 | ||
934 | gnus-Suspend-gnus-hook | |
935 | Called with no arguments when suspending (not exiting) GNUS, if | |
936 | that value is non-nil. | |
937 | ||
938 | gnus-Exit-gnus-hook | |
939 | Called with no arguments when exiting (not suspending) GNUS, if | |
940 | that value is non-nil." | |

1564 | ||
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 | |
1568 | `gnus-Subject-save-in-file'. The variable is initialized from the | |
1569 | SAVEDIR environment variable. | |

1583 | gnus-thread-hide-subtree | |
1584 | Non-nil means that thread subtrees are hidden initially. | |
1585 | ||
1586 | gnus-thread-hide-killed | |
1587 | Non-nil means that killed thread subtrees are hidden automatically. | |
1588 | ||
1589 | gnus-thread-ignore-subject | |

1593 | gnus-thread-indent-level | |
1594 | Indentation of thread subtrees. | |
1595 | ||
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. | |
1603 | ||
1604 | gnus-auto-extend-newsgroup | |

1607 | ||
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 | |
1612 | article in some newsgroups, set the variable to nil in | |
1613 | gnus-Select-group-hook or gnus-Apply-kill-hook. | |
1614 | ||
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. | |
1623 | ||
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'. | |
1627 | ||
1628 | gnus-auto-center-subject | |
1629 | Non-nil means the point of Subject Mode window is always kept | |
1630 | centered. | |

1632 | gnus-break-pages | |
1633 | Non-nil means an article is broken into pages at page delimiters. | |
1634 | This may not work with some versions of GNU Emacs earlier than | |
1635 | version 18.50. | |
1636 | ||
1637 | gnus-page-delimiter | |
1638 | Specifies a regexp describing line-beginnings that separate pages | |
1639 | of news article. | |
1640 | ||
1641 | [gnus-more-message is obsolete. overlay-arrow-string interfares | |
1642 | with other subsystems, such as dbx mode.] | |
1643 | ||
1644 | gnus-digest-show-summary | |

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. | |
1661 | ||
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. | |
1666 | ||
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. | |
1671 | ||
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. | |
1676 | ||
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. | |
1681 | ||
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. | |
1687 | ||
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. | |
1692 | ||
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. | |
1700 | ||
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. | |
1706 | ||
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." | |

3936 | ||
3937 | \\[gnus-Kill-file-kill-by-subject] Insert KILL command for current subject. | |
3938 | \\[gnus-Kill-file-kill-by-author] Insert KILL command for current author. | |
3939 | \\[gnus-Kill-file-apply-buffer] Apply current buffer to selected newsgroup. | |
3940 | \\[gnus-Kill-file-apply-last-sexp] Apply sexp before point to selected newsgroup. | |
3941 | \\[gnus-Kill-file-exit] Save file and exit editing KILL file. | |
3942 | \\[gnus-Info-find-node] Read Info about KILL file. | |
3943 | ||
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. | |
3950 | ||
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. | |
3956 | ||
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 | |
3964 | '(gnus-Subject-mark-as-read nil \"X\"). Make sure that COMMAND is | |
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. | |
3969 | ||
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: | |
3972 | ||
3973 | (gnus-kill \"Subject\" \"AI\") | |
3974 | ||
3975 | If you want to mark articles with `D' instead of `X', you can use | |
3976 | the following expression: | |
3977 | ||
3978 | (gnus-kill \"Subject\" \"AI\" \"d\") | |
3979 | ||
3980 | In this example it is assumed that the command | |
3981 | `gnus-Subject-mark-as-read-forward' is assigned to `d' in Subject Mode. | |
3982 | ||
3983 | It is possible to delete unnecessary headers which are marked with | |
3984 | `X' in a KILL file as follows: | |
3985 | ||
3986 | (gnus-expunge \"X\") | |
3987 | ||
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. | |
