"Major mode for editing kill files.
|
||
|
||
If you are using this mode - you probably shouldn't. Kill files
|
||
perform badly and paint with a pretty broad brush. Score files, on
|
||
the other hand, are vastly faster (40x speedup) and give you more
|
||
control over what to do.
|
||
|
||
In addition to Emacs-Lisp Mode, the following commands are available:
|
||
|
||
\\{gnus-kill-file-mode-map}
|
||
|
||
A kill file contains Lisp expressions to be applied to a selected
|
||
newsgroup. The purpose is to mark articles as read on the basis of
|
||
some set of regexps. A global kill file is applied to every newsgroup,
|
||
and a local kill file is applied to a specified newsgroup. Since a
|
||
global kill file is applied to every newsgroup, for better performance
|
||
use a local one.
|
||
|
||
A kill file can contain any kind of Emacs Lisp expressions expected
|
||
to be evaluated in the Summary buffer. Writing Lisp programs for this
|
||
purpose is not so easy because the internal working of Gnus must be
|
||
well-known. For this reason, Gnus provides a general function which
|
||
does this easily for non-Lisp programmers.
|
||
|
||
The `gnus-kill' function executes commands available in Summary Mode
|
||
by their key sequences. `gnus-kill' should be called with FIELD,
|
||
REGEXP and optional COMMAND and ALL. FIELD is a string representing
|
||
the header field or an empty string. If FIELD is an empty string, the
|
||
entire article body is searched for. REGEXP is a string which is
|
||
compared with FIELD value. COMMAND is a string representing a valid
|
||
key sequence in Summary mode or Lisp expression. COMMAND defaults to
|
||
'(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
|
||
executed in the Summary buffer. If the second optional argument ALL
|
||
is non-nil, the COMMAND is applied to articles which are already
|
||
marked as read or unread. Articles which are marked are skipped over
|
||
by default.
|
||
|
||
For example, if you want to mark articles of which subjects contain
|
||
the string `AI' as read, a possible kill file may look like:
|
||
|
||
(gnus-kill \"Subject\" \"AI\")
|
||
|
||
If you want to mark articles with `D' instead of `X', you can use
|
||
the following expression:
|
||
|
||
(gnus-kill \"Subject\" \"AI\" \"d\")
|
||
|
||
In this example it is assumed that the command
|
||
`gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
|
||
|
||
It is possible to delete unnecessary headers which are marked with
|
||
`X' in a kill file as follows:
|
||
|
||
(gnus-expunge \"X\")
|
||
|
||
If the Summary buffer is empty after applying kill files, Gnus will
|
||
exit the selected newsgroup normally. If headers which are marked
|
||
with `D' are deleted in a kill file, it is impossible to read articles
|
||
which are marked as read in the previous Gnus sessions. Marks other
|
||
than `D' should be used for articles which should really be deleted.
|
||
|
||
Entry to this mode calls emacs-lisp-mode-hook and
|
||
gnus-kill-file-mode-hook with no arguments, if that value is non-nil."
