26 ;;; Commentary:
28 ;;; Code:
49 "Your `.newsrc' file.
50 `.newsrc-SERVER' will be used instead if that exists."
55 "Whether to create backup files.
56 This variable takes the same values as the `version-control'
57 variable."
65 "Whether to write the startup file contents to a buffer then save
66 the buffer or write directly to the file. The buffer is faster
67 because all of the contents are written at once. The direct write
68 uses considerably less memory."
75 "Your Gnus Emacs-Lisp startup file name.
76 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
86 "The site-wide Gnus Emacs-Lisp startup file name, or nil if none.
87 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
92 "List of newsgroups to subscribe, when a user runs Gnus the first time.
93 The value should be a list of strings.
94 If it is t, Gnus will not do anything special the first time it is
95 started; it'll just use the normal newsgroups subscription methods."
100 "*Non-nil means that Gnus will use a dribble file to store user updates.
101 If Emacs should crash without saving the .newsrc files, complete
102 information can be restored from the dribble file."
107 "*The directory where dribble files will be saved.
108 If this variable is nil, the directory where the .newsrc files are
109 saved will be used."
114 "*Non-nil means that Gnus will run `gnus-find-new-newsgroups' at startup.
115 This normally finds new newsgroups by comparing the active groups the
116 servers have already reported with those Gnus already knows, either alive
117 or killed.
119 When any of the following are true, `gnus-find-new-newsgroups' will instead
120 ask the servers (primary, secondary, and archive servers) to list new
121 groups since the last time it checked:
122 1. This variable is `ask-server'.
123 2. This variable is a list of select methods (see below).
124 3. `gnus-read-active-file' is nil or `some'.
125 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
127 Thus, if this variable is `ask-server' or a list of select methods or
128 `gnus-read-active-file' is nil or `some', then the killed list is no
129 longer necessary, so you could safely set `gnus-save-killed-list' to nil.
131 This variable can be a list of select methods which Gnus will query with
132 the `ask-server' method in addition to the primary, secondary, and archive
133 servers.
135 Eg.
136 (setq gnus-check-new-newsgroups
139 If this variable is nil, then you have to tell Gnus explicitly to
151 "*Non-nil means that Gnus will check and remove bogus newsgroup at startup.
152 If this variable is nil, then you have to tell Gnus explicitly to
158 "*Non-nil means that Gnus will read the entire active file at startup.
159 If this variable is nil, Gnus will only know about the groups in your
160 `.newsrc' file.
162 If this variable is `some', Gnus will try to only read the relevant
163 parts of the active file from the server. Not all servers support
164 this, and it might be quite slow with other servers, but this should
165 generally be faster than both the t and nil value.
167 If you set this variable to nil or `some', you probably still want to
168 be told about new newsgroups that arrive. To do that, set
169 `gnus-check-new-newsgroups' to `ask-server'. This may not work
170 properly with all servers."
180 "Groups with levels less than or equal to this variable are unsubscribed.
181 Groups with levels less than `gnus-level-subscribed', which should be
191 "*New subscribed groups will be subscribed at this level."
196 "*New unsubscribed groups will be unsubscribed at this level."
201 "*Groups higher than this level won't be activated on startup.
202 Setting this variable to something low might save lots of time when
203 you have many groups that you aren't interested in."
208 "*If nil, Gnus will not check foreign newsgroups at startup.
209 If it is non-nil, it should be a number between one and nine. Foreign
210 newsgroups that have a level lower or equal to this number will be
211 activated on startup. For instance, if you want to active all
212 subscribed newsgroups, but not the rest, you'd set this variable to
213 `gnus-level-subscribed'.
215 If you subscribe to lots of newsgroups from different servers, startup
216 might take a while. By setting this variable to nil, you'll save time,
217 but you won't be told how many unread articles there are in the
218 groups."
224 "*Non-nil means that Gnus will read the `.newsrc' file.
225 Gnus always reads its own startup file, which is called
227 be readily understood by other newsreaders. If you don't plan on
228 using other newsreaders, set this variable to nil to save some time on
229 entry."
235 "*Non-nil means that Gnus will save the `.newsrc' file.
236 Gnus always saves its own startup file, which is called
238 be readily understood by other newsreaders. If you don't plan on
239 using other newsreaders, set this variable to nil to save some time on
240 exit."
245 "*If non-nil, save the list of killed groups to the startup file.
246 If you set this variable to nil, you'll save both time (when starting
247 and quitting) and space (both memory and disk), but it will also mean
248 that Gnus has no record of which groups are new and which are old, so
249 the automatic new newsgroups subscription methods become meaningless.
251 You should always set `gnus-check-new-newsgroups' to `ask-server' or
252 nil if you set this variable to nil.
254 This variable can also be a regexp. In that case, all groups that do
255 not match this regexp will be removed before saving the list."

272 Any lines in the active file matching this regular expression are
273 removed from the newsgroup list before anything else is done to it,
274 thus making them effectively non-existent."
279 "*Function(s) called with a group name when new group is detected.
280 A few pre-made functions are supplied: `gnus-subscribe-randomly'
281 inserts new groups at the beginning of the list of groups;
282 `gnus-subscribe-alphabetically' inserts new groups in strict
283 alphabetic order; `gnus-subscribe-hierarchically' inserts new groups
284 in hierarchical newsgroup order; `gnus-subscribe-interactively' asks
285 for your decision; `gnus-subscribe-killed' kills all new groups;
286 `gnus-subscribe-zombies' will make all new groups into zombies;
287 `gnus-subscribe-topics' will enter groups into the topics that
