38 "Your `.newsrc' file.
39 `.newsrc-SERVER' will be used instead if that exists."
44 "Your Gnus Emacs-Lisp startup file name.
45 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
55 "*The site-wide Gnus Emacs-Lisp startup file name, or nil if none.
56 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
61 "List of newsgroups to subscribe, when a user runs Gnus the first time.
62 The value should be a list of strings.
63 If it is t, Gnus will not do anything special the first time it is
64 started; it'll just use the normal newsgroups subscription methods."
69 "*Non-nil means that Gnus will use a dribble file to store user updates.
70 If Emacs should crash without saving the .newsrc files, complete
71 information can be restored from the dribble file."
76 "*The directory where dribble files will be saved.
77 If this variable is nil, the directory where the .newsrc files are
78 saved will be used."
83 "*Non-nil means that Gnus will run `gnus-find-new-newsgroups' at startup.
84 This normally finds new newsgroups by comparing the active groups the
85 servers have already reported with those Gnus already knows, either alive
86 or killed.
88 When any of the following are true, `gnus-find-new-newsgroups' will instead
89 ask the servers (primary, secondary, and archive servers) to list new
90 groups since the last time it checked:
91 1. This variable is `ask-server'.
92 2. This variable is a list of select methods (see below).
93 3. `gnus-read-active-file' is nil or `some'.
94 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
96 Thus, if this variable is `ask-server' or a list of select methods or
97 `gnus-read-active-file' is nil or `some', then the killed list is no
98 longer necessary, so you could safely set `gnus-save-killed-list' to nil.
100 This variable can be a list of select methods which Gnus will query with
101 the `ask-server' method in addition to the primary, secondary, and archive
102 servers.
104 Eg.
105 (setq gnus-check-new-newsgroups
108 If this variable is nil, then you have to tell Gnus explicitly to
120 "*Non-nil means that Gnus will check and remove bogus newsgroup at startup.
121 If this variable is nil, then you have to tell Gnus explicitly to
127 "*Non-nil means that Gnus will read the entire active file at startup.
128 If this variable is nil, Gnus will only know about the groups in your
129 `.newsrc' file.
131 If this variable is `some', Gnus will try to only read the relevant
132 parts of the active file from the server. Not all servers support
133 this, and it might be quite slow with other servers, but this should
134 generally be faster than both the t and nil value.
136 If you set this variable to nil or `some', you probably still want to
137 be told about new newsgroups that arrive. To do that, set
138 `gnus-check-new-newsgroups' to `ask-server'. This may not work
139 properly with all servers."
146 "*Groups with levels less than or equal to this variable are subscribed."
151 "*Groups with levels less than or equal to this variable are unsubscribed.
152 Groups with levels less than `gnus-level-subscribed', which should be
153 less than this variable, are subscribed."
158 "*Groups with this level are zombie groups."
163 "*Groups with this level are killed."
168 "*New subscribed groups will be subscribed at this level."
173 "*New unsubscribed groups will be unsubscribed at this level."
178 "*Groups higher than this level won't be activated on startup.
179 Setting this variable to something low might save lots of time when
180 you have many groups that you aren't interested in."
185 "*If nil, Gnus will not check foreign newsgroups at startup.
186 If it is non-nil, it should be a number between one and nine. Foreign
187 newsgroups that have a level lower or equal to this number will be
188 activated on startup. For instance, if you want to active all
189 subscribed newsgroups, but not the rest, you'd set this variable to
190 `gnus-level-subscribed'.
192 If you subscribe to lots of newsgroups from different servers, startup
193 might take a while. By setting this variable to nil, you'll save time,
194 but you won't be told how many unread articles there are in the
195 groups."
201 "*Non-nil means that Gnus will save the `.newsrc' file.
202 Gnus always saves its own startup file, which is called
204 be readily understood by other newsreaders. If you don't plan on
205 using other newsreaders, set this variable to nil to save some time on
206 exit."
211 "*If non-nil, save the list of killed groups to the startup file.
212 If you set this variable to nil, you'll save both time (when starting
213 and quitting) and space (both memory and disk), but it will also mean
214 that Gnus has no record of which groups are new and which are old, so
215 the automatic new newsgroups subscription methods become meaningless.
217 You should always set `gnus-check-new-newsgroups' to `ask-server' or
218 nil if you set this variable to nil.
220 This variable can also be a regexp. In that case, all groups that do
221 not match this regexp will be removed before saving the list."
230 )
232 "*A regexp to match uninteresting newsgroups in the active file.
233 Any lines in the active file matching this regular expression are
234 removed from the newsgroup list before anything else is done to it,
235 thus making them effectively non-existent."
240 "*Function called with a group name when new group is detected.
241 A few pre-made functions are supplied: `gnus-subscribe-randomly'
242 inserts new groups at the beginning of the list of groups;
243 `gnus-subscribe-alphabetically' inserts new groups in strict
244 alphabetic order; `gnus-subscribe-hierarchically' inserts new groups
245 in hierarchical newsgroup order; `gnus-subscribe-interactively' asks
246 for your decision; `gnus-subscribe-killed' kills all new groups;

267 the subscription method in this variable."

283 If the user pressed `d', Gnus will descend the hierarchy, `y' will
284 subscribe to all newsgroups in the hierarchy and `s' will skip this
285 hierarchy in its entirety."
291 "*All new groups that match this regexp will be subscribed automatically.
292 Note that this variable only deals with new groups. It has no effect
293 whatsoever on old groups.
295 New groups that match this regexp will not be handled by
