ruby-dev.el

ruby-dev.el is a module that tries to bring some of SLIME's features to Ruby. It provides:

• Evaluation of code to a live process (C-x C-e, etc.)
• Copying of results of the evaluated ruby code into buffers via the kill chain (preface eval commands with C-u)
• Access to Ruby documentation (C-c C-d)
• A wrapper around a Ruby REPL (C-c C-i)

For more details, see the help within Emacs.
