71 "Major mode for editing kill files.
|
|
|
72
|
|
|
73 If you are using this mode - you probably shouldn't. Kill files
|
|
|
74 perform badly and paint with a pretty broad brush. Score files, on
|
|
|
75 the other hand, are vastly faster (40x speedup) and give you more
|
|
|
76 control over what to do.
|
|
|
77
|
|
|
78 In addition to Emacs-Lisp Mode, the following commands are available:
|
|
|
79
|
|
|
80 \\{gnus-kill-file-mode-map}
|
|
|
81
|
|
|
82 A kill file contains Lisp expressions to be applied to a selected
|
|
|
83 newsgroup. The purpose is to mark articles as read on the basis of
|
|
|
84 some set of regexps. A global kill file is applied to every newsgroup,
|
|
|
85 and a local kill file is applied to a specified newsgroup. Since a
|
|
|
86 global kill file is applied to every newsgroup, for better performance
|
|
|
87 use a local one.
|
|
|
88
|
|
|
89 A kill file can contain any kind of Emacs Lisp expressions expected
|
|
|
90 to be evaluated in the Summary buffer. Writing Lisp programs for this
|
|
|
91 purpose is not so easy because the internal working of Gnus must be
|
|
|
92 well-known. For this reason, Gnus provides a general function which
|
|
|
93 does this easily for non-Lisp programmers.
|
|
|
94
|
|
|
95 The `gnus-kill' function executes commands available in Summary Mode
|
|
70
|
96 by their key sequences. `gnus-kill' should be called with FIELD,
|
|
0
|
97 REGEXP and optional COMMAND and ALL. FIELD is a string representing
|
|
|
98 the header field or an empty string. If FIELD is an empty string, the
|
|
|
99 entire article body is searched for. REGEXP is a string which is
|
|
70
|
100 compared with FIELD value. COMMAND is a string representing a valid
|
|
|
101 key sequence in Summary mode or Lisp expression. COMMAND defaults to
|
|
0
|
102 '(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
|
|
|
103 executed in the Summary buffer. If the second optional argument ALL
|
|
|
104 is non-nil, the COMMAND is applied to articles which are already
|
|
|
105 marked as read or unread. Articles which are marked are skipped over
|
|
|
106 by default.
|
|
|
107
|
|
|
108 For example, if you want to mark articles of which subjects contain
|
|
|
109 the string `AI' as read, a possible kill file may look like:
|
|
|
110
|
|
|
111 (gnus-kill \"Subject\" \"AI\")
|
|
|
112
|
|
|
113 If you want to mark articles with `D' instead of `X', you can use
|
|
|
114 the following expression:
|
|
|
115
|
|
|
116 (gnus-kill \"Subject\" \"AI\" \"d\")
|
|
|
117
|
|
|
118 In this example it is assumed that the command
|
|
|
119 `gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
|
|
|
120
|
|
|
121 It is possible to delete unnecessary headers which are marked with
|
|
|
122 `X' in a kill file as follows:
|
|
|
123
|
|
|
124 (gnus-expunge \"X\")
|
|
|
125
|
|
|
126 If the Summary buffer is empty after applying kill files, Gnus will
|
|
|
127 exit the selected newsgroup normally. If headers which are marked
|
|
|
128 with `D' are deleted in a kill file, it is impossible to read articles
|
|
|
129 which are marked as read in the previous Gnus sessions. Marks other
|
|
|
130 than `D' should be used for articles which should really be deleted.
|
|
|
131
|
|
|
132 Entry to this mode calls emacs-lisp-mode-hook and
|
|
|
133 gnus-kill-file-mode-hook with no arguments, if that value is non-nil."
