;;; Commentary:
;; This is an ERC module to enable flyspell mode in ERC buffers. This
;; ensures correct behavior of flyspell, and even sets up a
;; channel-local dictionary if so required.
;;; Code:
(require 'erc)
(require 'flyspell)
;;;###autoload (autoload 'erc-spelling-mode "erc-spelling" nil t)
(define-erc-module spelling nil
"Enable flyspell mode in ERC buffers."
;; Use erc-connect-pre-hook instead of erc-mode-hook as pre-hook is
;; called AFTER the server buffer is initialized.
((add-hook 'erc-connect-pre-hook 'erc-spelling-init)
(mapc (lambda (buffer)
(with-current-buffer buffer (erc-spelling-init)))
(erc-buffer-list)))
((remove-hook 'erc-connect-pre-hook 'erc-spelling-init)
(mapc (lambda (buffer)
(with-current-buffer buffer (flyspell-mode 0)))
(erc-buffer-list))))
(defcustom erc-spelling-dictionaries nil
"An alist mapping buffer names to dictionaries.
The `car' of every cell is a buffer name, the `cadr' is the
string name of an associated dictionary.
The dictionary is inherited from server buffers, so if you want a
default dictionary for some server, you can use a server buffer
name here."
