What Gnus does when it encounters a new group is determined by the
gnus-subscribe-newsgroup-method variable.
This variable should contain a function. This function will be called with the name of the new group as the only parameter.
Some handy pre-fab functions are:
gnus-subscribe-zombies ¶Make all new groups zombies (see Group Levels). This is the default. You can browse the zombies later (with A z) and either kill them all off properly (with S z), or subscribe to them (with u).
gnus-subscribe-randomly ¶Subscribe all new groups in arbitrary order. This really means that all new groups will be added at “the top” of the group buffer.
gnus-subscribe-alphabetically ¶Subscribe all new groups in alphabetical order.
gnus-subscribe-hierarchically ¶Subscribe all new groups hierarchically. The difference between this
function and gnus-subscribe-alphabetically is slight.
gnus-subscribe-alphabetically will subscribe new groups in a strictly
alphabetical fashion, while this function will enter groups into its
hierarchy. So if you want to have the ‘rec’ hierarchy before the
‘comp’ hierarchy, this function will not mess that configuration
up. Or something like that.
gnus-subscribe-interactively ¶Subscribe new groups interactively. This means that Gnus will ask you about all new groups. The groups you choose to subscribe to will be subscribed hierarchically.
gnus-subscribe-killed ¶Kill all new groups.
gnus-subscribe-topics ¶Put the groups into the topic that has a matching subscribe topic
parameter (see Topic Parameters). For instance, a subscribe
topic parameter that looks like
"nnml"
will mean that all groups that match that regex will be subscribed under that topic.
If no topics match the groups, the groups will be subscribed in the top-level topic.
A closely related variable is
gnus-subscribe-hierarchical-interactive. (That’s quite a
mouthful.) If this variable is non-nil, Gnus will ask you in a
hierarchical fashion whether to subscribe to new groups or not. Gnus
will ask you for each sub-hierarchy whether you want to descend the
hierarchy or not.
One common mistake is to set the variable a few paragraphs above
(gnus-subscribe-newsgroup-method) to
gnus-subscribe-hierarchical-interactive. This is an error. This
will not work. This is ga-ga. So don’t do it.
