;; This allows us to customize an `erc-autojoin-channels-alist'. As

|
;; we /JOIN and /PART channels, this alist is updated to reflect our
|
|
;; current setup, so that when we reconnect, we rejoin the same

|
;; value will be used when we reconnect in our next Emacs session.

"Alist of channels to autojoin on IRC networks.

Every element in the alist has the form (SERVER . CHANNELS).
|
|
SERVER is a regexp matching the server, and channels is the
|
|
list of channels to join.
|
|
|
|
If the channel(s) require channel keys for joining, the passwords
|
|
are found via auth-source. For instance, if you use ~/.authinfo
|
|
as your auth-source backend, then put something like the
|
|
following in that file:
|
|
|
|
machine irc.example.net login \"#fsf\" password sEcReT
|
|
|
|
Customize this variable to set the value for your first connect.
|
|
Once you are connected and join and part channels, this alist
|
|
keeps track of what channels you are on, and will join them
|
|
again when you get disconnected. When you restart Emacs, however,
|
|
those changes are lost, and the customization you saved the last
|
|
time is used again."
