25 ;;; Commentary:
27 ;;; Code:
39 "Your `.newsrc' file.
40 `.newsrc-SERVER' will be used instead if that exists."
45 "Your Gnus Emacs-Lisp startup file name.
46 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
56 "The site-wide Gnus Emacs-Lisp startup file name, or nil if none.
57 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
62 "List of newsgroups to subscribe, when a user runs Gnus the first time.
63 The value should be a list of strings.
64 If it is t, Gnus will not do anything special the first time it is
65 started; it'll just use the normal newsgroups subscription methods."
70 "*Non-nil means that Gnus will use a dribble file to store user updates.
71 If Emacs should crash without saving the .newsrc files, complete
72 information can be restored from the dribble file."
77 "*The directory where dribble files will be saved.
78 If this variable is nil, the directory where the .newsrc files are
79 saved will be used."
84 "*Non-nil means that Gnus will run `gnus-find-new-newsgroups' at startup.
85 This normally finds new newsgroups by comparing the active groups the
86 servers have already reported with those Gnus already knows, either alive
87 or killed.
89 When any of the following are true, `gnus-find-new-newsgroups' will instead
90 ask the servers (primary, secondary, and archive servers) to list new
91 groups since the last time it checked:
92 1. This variable is `ask-server'.
93 2. This variable is a list of select methods (see below).
94 3. `gnus-read-active-file' is nil or `some'.
95 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
97 Thus, if this variable is `ask-server' or a list of select methods or
98 `gnus-read-active-file' is nil or `some', then the killed list is no
99 longer necessary, so you could safely set `gnus-save-killed-list' to nil.
101 This variable can be a list of select methods which Gnus will query with
102 the `ask-server' method in addition to the primary, secondary, and archive
103 servers.
105 Eg.
106 (setq gnus-check-new-newsgroups
109 If this variable is nil, then you have to tell Gnus explicitly to
121 "*Non-nil means that Gnus will check and remove bogus newsgroup at startup.
122 If this variable is nil, then you have to tell Gnus explicitly to
128 "*Non-nil means that Gnus will read the entire active file at startup.
129 If this variable is nil, Gnus will only know about the groups in your
130 `.newsrc' file.
132 If this variable is `some', Gnus will try to only read the relevant
133 parts of the active file from the server. Not all servers support
134 this, and it might be quite slow with other servers, but this should
135 generally be faster than both the t and nil value.
137 If you set this variable to nil or `some', you probably still want to
138 be told about new newsgroups that arrive. To do that, set
139 `gnus-check-new-newsgroups' to `ask-server'. This may not work
140 properly with all servers."
150 "Groups with levels less than or equal to this variable are unsubscribed.
151 Groups with levels less than `gnus-level-subscribed', which should be
161 "*New subscribed groups will be subscribed at this level."
166 "*New unsubscribed groups will be unsubscribed at this level."
171 "*Groups higher than this level won't be activated on startup.
172 Setting this variable to something low might save lots of time when
173 you have many groups that you aren't interested in."
178 "*If nil, Gnus will not check foreign newsgroups at startup.
179 If it is non-nil, it should be a number between one and nine. Foreign
180 newsgroups that have a level lower or equal to this number will be
181 activated on startup. For instance, if you want to active all
182 subscribed newsgroups, but not the rest, you'd set this variable to
183 `gnus-level-subscribed'.
185 If you subscribe to lots of newsgroups from different servers, startup
186 might take a while. By setting this variable to nil, you'll save time,
187 but you won't be told how many unread articles there are in the
188 groups."
194 "*Non-nil means that Gnus will read the `.newsrc' file.
195 Gnus always reads its own startup file, which is called
197 be readily understood by other newsreaders. If you don't plan on
198 using other newsreaders, set this variable to nil to save some time on
199 entry."
205 "*Non-nil means that Gnus will save the `.newsrc' file.
206 Gnus always saves its own startup file, which is called
208 be readily understood by other newsreaders. If you don't plan on
209 using other newsreaders, set this variable to nil to save some time on
210 exit."
215 "*If non-nil, save the list of killed groups to the startup file.
216 If you set this variable to nil, you'll save both time (when starting
217 and quitting) and space (both memory and disk), but it will also mean
218 that Gnus has no record of which groups are new and which are old, so
219 the automatic new newsgroups subscription methods become meaningless.
221 You should always set `gnus-check-new-newsgroups' to `ask-server' or
222 nil if you set this variable to nil.
224 This variable can also be a regexp. In that case, all groups that do
225 not match this regexp will be removed before saving the list."
234 )
236 "*A regexp to match uninteresting newsgroups in the active file.
237 Any lines in the active file matching this regular expression are
238 removed from the newsgroup list before anything else is done to it,
239 thus making them effectively non-existent."
244 "*Function called with a group name when new group is detected.
245 A few pre-made functions are supplied: `gnus-subscribe-randomly'
246 inserts new groups at the beginning of the list of groups;
247 `gnus-subscribe-alphabetically' inserts new groups in strict
248 alphabetic order; `gnus-subscribe-hierarchically' inserts new groups
249 in hierarchical newsgroup order; `gnus-subscribe-interactively' asks
250 for your decision; `gnus-subscribe-killed' kills all new groups;
251 `gnus-subscribe-zombies' will make all new groups into zombies;

274 the subscription method in this variable."

291 subscribe to all newsgroups in the hierarchy and `s' will skip this
292 hierarchy in its entirety."

300 whatsoever on old groups.
