18.104.22.168 Hooking New Back Ends Into Gnus
Having Gnus start using your new back end is rather easy—you just
declare it with the
gnus-declare-backend functions. This will
enter the back end into the
gnus-declare-backend takes two parameters—the back end name and
an arbitrary number of abilities.
Here's an example:
(gnus-declare-backend "nnchoke" 'mail 'respool 'address)
The above line would then go in the nnchoke.el file.
The abilities can be:
- This is a mailish back end—followups should (probably) go via mail.
- This is a newsish back end—followups should (probably) go via news.
- This back end supports both mail and news.
- This is neither a post nor mail back end—it's something completely
- It supports respooling—or rather, it is able to modify its source
articles and groups.
- The name of the server should be in the virtual server name. This is
true for almost all back ends.
- The user should be prompted for an address when doing commands like
B in the group buffer. This is true for back ends like
nntp, but not
nnmbox, for instance.
