Subject: eruby and emacs mmm-mode

Just thought I'd share this neat little hint for those
of you that are creating eruby files with emacs.  There's
a emacs mode availiable called mmm-mode.  It allows
you to have a major mode and a submode active. For my eruby
files, I have SGML-mode active with ruby-mode between the
<% and %> marks.  Its nice.



The following is what I'm running locally to configure mmm.
I'm using the Debian testing distro with apt provided emacs21 and mmm-mode.


# this line in my .emacs, prepend your desired path
(load "add-my-mmm-mode.el")



# the add-my-mmm-mode.el file
(require 'mmm-auto)

(setq mmm-global-mode 'maybe)

(mmm-add-classes
 '((eruby
    :submode ruby-mode
;    :face mmm-declaration-submode-face
    :front "<%[=]?"
    :back  "%>")))

;(mmm-add-mode-ext-class MODE EXTENSION CLASS)
(mmm-add-mode-ext-class 'sgml-mode "\\.rhtml$" 'eruby)



Have fun,
