ephemeral for dummies?

ephemeral for dummies?

[Kai Grossjohann]

Hi there,

suppose I've got a backend (you know it's nndb.el :).  Suppose further
I want to extend this to create ephemeral groups.  What do I have to
change in nndb.el to enable it to create ephemeral groups, too?  (I'd
be willing to create yet another backend nneb.el (e=ephemeral) if
that's easier.)

Just in case you're wondering...  NNDB has an option to search its
database.  This works by creating groups which have "=" in their
name.  NNDB then creates a new group on the fly and puts the search
result into it.  This group can be manipulated using the normal
measures.  I just thought it would be easier to be able to create an
ephemeral group rather than to always create a `real' group (using `G
m') and to kill it after use.

The backend doesn't have to know whether the group in question is
ephemeral or not -- which should save some work.  Just call
`gnus-group-read-ephemeral-group' to select an ephemeral group.  It
takes four parameters -- the group name, the select method, a flag
that says whether the group should be activated or not, and a window
configuration that says where Gnus should go when the user presses `q'
in the ephemeral group.

Gnus uses this function when `C-d'ing in the summary buffer, or when
reading nneething groups.
