;;; 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)
(require 'ispell)

(defconst erc-spelling-version "$Revision$"
  "ERC spelling revision.")

(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.")

;;;###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))
  ((remove-hook 'erc-connect-pre-hook 'erc-spelling-init)))

(defun erc-spelling-init ()
  "Enable flyspell mode in an ERC buffer."

                (not (string= name (downcase (caar dicts)))))
      (setq dicts (cdr dicts)))
    (setq ispell-local-dictionary
          (if dicts
              (cadr (car dicts))
