See the emacswiki for setting up flymake

  http://www.emacswiki.org/emacs/FlymakeRuby

I'm using emacs-rails which already sets this up for you:

  http://dima-exe.ru/rails-on-emacs

(I don't really like the fact that emacs-rails configures so much
stuff for you: it's generally easier to turn on a feature you want
than to turn off a feature that you don't want - in the latter case
you don't know where it was activated and what was done to configure
it.)

For ri, I use the fastri gem which includes the `ri-emacs'
executable. Note that you have to start a fastri-server before you can
use it (should be done in some startup script). You still need to get
ri-ruby.el from http://rubyforge.org/projects/ri-emacs/ and put it
somewhere in your emacs load-path:

  (mapc (lambda (func)
          (autoload func "ri-ruby" nil t))
        '(ri ri-ruby-complete-symbol ri-ruby-show-args))

  ;; this only works if ri-emacs can be found in your PATH
  (setq ri-ruby-script (locate-file "ri-emacs" exec-path))

  ;; the default ANSI colours are not really readable with a light background
  (setq ansi-color-names-vector ["black" "red" "#009900" "yellow" "blue" "magenta" "#990099" "white"])
  (setq ansi-color-map (ansi-color-make-color-map))

  (add-hook 'ruby-mode-hook
            (lambda ()
              (local-set-key "\M-\C-i" 'ri-ruby-complete-symbol)
              (local-set-key (kbd "<f4>") 'ri-ruby-show-args)))

Apart from the rails-specific stuff I only have these smaler
customizations for ruby:

  ;; allows for navigation by word in camel-cased constants
  (defun turn-on-c-subword-mode () (c-subword-mode 1))
  (add-hook 'ruby-mode-hook 'turn-on-c-subword-mode)

  ;; highlight some keywords
  (font-lock-add-keywords 'ruby-mode
   '(("\\<\\(FIXME\\|HACK\\|XXX\\|FLUNK\\|TODO\\|ToDo\\)" 1
   font-lock-warning-face prepend)))

  ;; highlights matching blocks, get it from
  ;; http://www.emacswiki.org/emacs/ruby-block.el
  (autoload 'ruby-block-mode "ruby-block" nil t)
  (add-hook 'ruby-mode-hook (lambda () (ruby-block-mode t)))

My other customizations are either too specific (rails) or too general
to mention here. 

HTH, 

Anselm

Can anyone, who program on Ruby, share the bit of ~/.emacs with ruby
configuration, and the ruby-files for emacs? I only install the irb and
ruby-mode, but ri, flymode - i cannot.
