Rinari Is Not A Ruby IDE. Well, ok it kind of is. Rinari is an Emacs minor mode that is aimed towards making Emacs into a top-notch Ruby and Rails development environment. IMPORTANT NOTE: The only currently-supported installation method is via package.el, via Marmalade or MELPA. While other methods might work, they are unsupported. For a screencast of Rinari see http://vimeo.com/2854412 For the latest version see http://github.com/eschulte/rinari/tree/master For somewhat outdated installation instructions and documentation see http://rinari.rubyforge.org For discussion of Ruby on Rails related Emacs development see http://groups.google.com/group/emacs-on-rails
