gnus: Server Variables
6.1.5 Server Variables
----------------------
One sticky point when defining variables (both on back ends and in Emacs
in general) is that some variables are typically initialized from other
variables when the definition of the variables is being loaded. If you
change the “base” variable after the variables have been loaded, you
won’t change the “derived” variables.
This typically affects directory and file variables. For instance,
‘nnml-directory’ is ‘~/Mail/’ by default, and all ‘nnml’ directory
variables are initialized from that variable, so ‘nnml-active-file’ will
be ‘~/Mail/active’. If you define a new virtual ‘nnml’ server, it will
_not_ suffice to set just ‘nnml-directory’—you have to explicitly set
all the file variables to be what you want them to be. For a complete
list of variables for each back end, see each back end’s section later
in this manual, but here’s an example ‘nnml’ definition:
(nnml "public"
(nnml-directory "~/my-mail/")
(nnml-active-file "~/my-mail/active")
(nnml-newsgroups-file "~/my-mail/newsgroups"))
Server variables are often called “server parameters”.
