Emacs ruby-mode

To install ruby-mode for emacs, I followed the directions at the digital sanitation engineering blog. I pretty much did exactly the same thing-- I don't know why I wrote my own post-- I suppose it is good just for my records.

Then added the following to my .emacs:

(add-to-list 'load-path "~/.emacs.d/site-lisp/ruby")
(autoload 'ruby-mode "ruby-mode"
    "Mode for editing ruby source files")
(add-to-list 'auto-mode-alist '("\\.rb$" . ruby-mode))
(add-to-list 'interpreter-mode-alist '("ruby" . ruby-mode))
(autoload 'run-ruby "inf-ruby"
    "Run an inferior Ruby process")
(autoload 'inf-ruby-keys "inf-ruby"
    "Set local key defs for inf-ruby in ruby-mode")
(add-hook 'ruby-mode-hook
    '(lambda ()
        (inf-ruby-keys)))
;; If you have Emacs 19.2x or older, use rubydb2x                              
(autoload 'rubydb "rubydb3x" "Ruby debugger" t)
;; uncomment the next line if you want syntax highlighting                     
(add-hook 'ruby-mode-hook 'turn-on-font-lock)
