* Intro

I am a Ruby developer by trade (and still /heart), but I am no longer a code 

* Irb

Inf-Ruby allows for interactive REPL inside Emacs.
You can create a buffer with IRB, you can send code there and you can run =babel= code blocks in ruby.
Cool!

#+begin_src emacs-lisp
  (use-package inf-ruby
  :ensure t)
#+end_src

* Robe

Yes, we have LSP but they work /poorly/ in my experience.
Robe is a major mode designed to work with Ruby so let's ride it.

#+begin_src emacs-lisp
  (use-package robe
  :ensure t)
#+end_src

And I want it to be enable whenever I am /doing ruby./
#+begin_src emacs-lisp
  (add-hook 'ruby-mode-hook 'robe-mode)
  (add-hook 'ruby-ts-mode-hook 'robe-mode)
#+end_src

Let's also add it to autocomplete (for the future, as I have yet to setup company)
#+begin_src emacs-lisp
  (eval-after-load 'company
    '(push 'company-robe company-backends))
#+end_src
