Ruby-mode in emacs

Ruby
1

Hi,
I’m new to emacs, just bought a book and started my way into it.
How could I enable ruby-mode in emacs?
I copied all 4 *.el files to C:\emacs-21.3\lisp\progmodes, and enabled
global font lock (through the menu)
I have the syntax coloring but not auto-complete or anything else.
How do I enable auto-complete? and is there another features in these
modes?

Thanks,

  • H

Here is my .emacs file:
(autoload 'ruby-mode “ruby-mode” “Ruby editing mode.” t)
(setq auto-mode-alist (cons '("\.rb$" . ruby-mode) auto-mode-alist))

(custom-set-variables
;; custom-set-variables was added by Custom – don’t edit or cut/paste
it!
;; Your init file should contain only one such instance.
'(case-fold-search t)
'(current-language-environment “Latin-1”)
'(default-input-method “latin-1-prefix”)
'(global-font-lock-mode t nil (font-lock)))
(custom-set-faces
;; custom-set-faces was added by Custom – don’t edit or cut/paste it!
;; Your init file should contain only one such instance.
)

Do you complete Ruby tokens like emacs-lisp?

If you want to complete Ruby tokens, use exuberant ctags.

First make `TAGS’, the tag file.
$ ctags -e *.rb

Then enable the tag file.
M-x visit-tags-table

(defun ruby-mode-hook0 ()
(define-key ruby-mode-map “\M-\C-i” 'complete-tag)
)

(add-hook 'inferior-ruby-mode-hook 'inferior-ruby-mode-hook0)

And if you want to complete in inferior-ruby-mode, you can use irbsh.
Irbsh extends inferior-ruby-mode to enable you to complete Ruby tokens,
and to execute shell commands.

If you want to complete Ruby tokens, use exuberant ctags.

FWIW the Zeus for Windows IDE provides seamless integration
with the Exuberant Ctags utility:

Zeus IDE - Programming environment for Windows developers

Basically you create a project/workspace, add the source
files to the project and Zeus will automatically manage
the updating of the ctags information.
