Gnus still supports those pesky old kill files. In fact, the kill file entries can now be expiring, which is something I wrote before Daniel Quinlan thought of doing score files, so I've left the code in there.
In short, kill processing is a lot slower (and I do mean a lot) than score processing, so it might be a good idea to rewrite your kill files into score files.
Anyway, a kill file is a normal
emacs-lisp file. You can put any
forms into this file, which means that you can use kill files as some
sort of primitive hook function to be run on group entry, even though
that isn't a very good idea.
Normal kill files look like this:
(gnus-kill "From" "Lars Ingebrigtsen") (gnus-kill "Subject" "ding") (gnus-expunge "X")
This will mark every article written by me as read, and remove the marked articles from the summary buffer. Very useful, you'll agree.
Other programs use a totally different kill file syntax. If Gnus
encounters what looks like a
rn kill file, it will take a stab at
Two summary functions for editing a gnus kill file:
Two group mode functions for editing the kill files:
Kill file variables:
gnus-kill-file-namevariable. The “global” kill file (not in the score file sense of “global”, of course) is just called KILL.
nil, Gnus will save the kill file after processing, which is necessary if you use expiring kills.
(gnus-apply-kill-file)by default. If you want to ignore the kill file if you have a score file for the same group, you can set this hook to
(gnus-apply-kill-file-unless-scored). If you don't want kill files to be processed, you should set this variable to
