Now, you all know about the `.newsrc
' file. All subscription
information is traditionally stored in this file.
Things got a bit more complicated with GNUS. In addition to
keeping the `.newsrc
' file updated, it also used a file called
`.newsrc.el
' for storing all the information that didn't fit into
the `.newsrc
' file. (Actually, it also duplicated everything in
the `.newsrc
' file.) GNUS would read whichever one of these
files was the most recently saved, which enabled people to swap between
GNUS and other newsreaders.
That was kinda silly, so Gnus went one better: In addition to the
`.newsrc
' and `.newsrc.el
' files, Gnus also has a file called
`.newsrc.eld
'. It will read whichever of these files that are most
recent, but it will never write a `.newsrc.el
' file. You should
never delete the `.newsrc.eld
' file---it contains much information
not stored in the `.newsrc
' file.
You can turn off writing the `.newsrc
' file by setting
gnus-save-newsrc-file
to nil
, which means you can delete
the file and save some space, as well as exiting from Gnus faster.
However, this will make it impossible to use other newsreaders than
Gnus. But hey, who would want to, right?
If gnus-save-killed-list
(default t
) is nil
, Gnus
will not save the list of killed groups to the startup file. This will
save both time (when starting and quitting) and space (on disk). It
will also mean that Gnus has no record of what groups are new or old,
so the automatic new groups subscription methods become meaningless.
You should always set gnus-check-new-newsgroups
to nil
or
ask-server
if you set this variable to nil
(see New Groups). This variable can also be a regular expression. If that's
the case, remove all groups that do not match this regexp before
saving. This can be useful in certain obscure situations that involve
several servers where not all servers support ask-server
.
The gnus-startup-file
variable says where the startup files are.
The default value is `~/.newsrc
', with the Gnus (El Dingo) startup
file being whatever that one is, with a `.eld
' appended.
gnus-save-newsrc-hook
is called before saving any of the newsrc
files, while gnus-save-quick-newsrc-hook
is called just before
saving the `.newsrc.eld
' file, and
gnus-save-standard-newsrc-hook
is called just before saving the
`.newsrc
' file. The latter two are commonly used to turn version
control on or off. Version control is on by default when saving the
startup files. If you want to turn backup creation off, say something like:
(defun turn-off-backup () (set (make-local-variable 'backup-inhibited) t)) (add-hook 'gnus-save-quick-newsrc-hook 'turn-off-backup) (add-hook 'gnus-save-standard-newsrc-hook 'turn-off-backup)
When Gnus starts, it will read the gnus-site-init-file
(`.../site-lisp/gnus
' by default) and gnus-init-file
(`~/.gnus
' by default) files. These are normal Emacs Lisp files
and can be used to avoid cluttering your `~/.emacs
' and
`site-init
' files with Gnus stuff. Gnus will also check for files
with the same names as these, but with `.elc
' and `.el
'
suffixes. In other words, if you have set gnus-init-file
to
`~/.gnus
', it will look for `~/.gnus.elc
', `~/.gnus.el
',
and finally `~/.gnus
' (in this order).
