The alist can be customized, so that the customized 32;; value will be used when we reconnect in our next Emacs session. 33 34;;; Code: 35 36(require 'erc) 37(eval-when-compile (require 'cl)) 38 39(defgroup erc-autojoin nil 40 "Enable autojoining." 41 :group 'erc) 42 43;;;###autoload (autoload 'erc-autojoin-mode "erc-join" nil t) 44(define-erc-module autojoin nil 45 "Makes ERC autojoin on connects and reconnects." 46 ((add-hook 'erc-after-connect 'erc-autojoin-channels) 47 (add-hook 'erc-server-JOIN-functions 'erc-autojoin-add) 48 (add-hook 'erc-server-PART-functions 'erc-autojoin-remove)) 49 ((remove-hook 'erc-after-connect 'erc-autojoin-channels) 50 (remove-hook 'erc-server-JOIN-functions 'erc-autojoin-add) 51 (remove-hook 'erc-server-PART-functions 'erc-autojoin-remove))) 52 53(defcustom erc-autojoin-channels-alist nil 54 "Alist of channels to autojoin on IRC networks. 55Every element in the alist has the form (SERVER .
