2.11 Spelling

There are two popular ways to have Emacs spell-check your messages: ispell and flyspell. ispell is the older and probably more popular package. You typically first write the message, and then run the entire thing through ispell and fix all the typos. To have this happen automatically when you send a message, put something like the following in your .emacs file:

     (add-hook 'message-send-hook 'ispell-message)

If you're in the habit of writing in different languages, this can be controlled by the ispell-message-dictionary-alist variable:

     (setq ispell-message-dictionary-alist
           '(("^Newsgroups:.*\\bde\\." . "deutsch8")
             (".*" . "default")))

ispell depends on having the external ‘ispell’ command installed.

The other popular method is using flyspell. This package checks your spelling while you're writing, and marks any mis-spelled words in various ways.

To use flyspell, put something like the following in your .emacs file:

     (defun my-message-setup-routine ()
       (flyspell-mode 1))
     (add-hook 'message-setup-hook 'my-message-setup-routine)

flyspell depends on having the external ‘ispell’ command installed.
