;;; Commentary:
;;
;; inf-ruby provides a REPL buffer connected to a Ruby subprocess.
;;
;; If you're installing manually, you'll need to:
;; * drop the file somewhere on your load path (perhaps ~/.emacs.d)
;; * Add the following lines to your .emacs file:
;;
;; (autoload 'inf-ruby "inf-ruby" "Run an inferior Ruby process" t)
;; (add-hook 'ruby-mode-hook 'inf-ruby-minor-mode)
;;
;; Or, for enh-ruby-mode:
;;
;; (add-hook 'enh-ruby-mode-hook 'inf-ruby-minor-mode)
;;
;; Installation via ELPA interface does the above for you
;; automatically.
;;
;; Additionally, consider adding
;;
;; (add-hook 'compilation-filter-hook 'inf-ruby-auto-enter)
;;
;; to your init file to automatically switch from common Ruby compilation
;; modes to interact with a debugger.
;;
;; To call `inf-ruby-console-auto' more easily, you can, for example,
;; replace the original `inf-ruby' binding:
;;
;; (eval-after-load 'inf-ruby
;; '(define-key inf-ruby-minor-mode-map
;; (kbd "C-c C-s") 'inf-ruby-console-auto))

"Major mode for interacting with an inferior Ruby REPL process.
A simple IRB process can be fired up with \\[inf-ruby].
To launch a REPL with project-specific console instead, type
\\[inf-ruby-console-auto]. It recognizes several
project types, including Rails, gems and anything with `racksh'
in their Gemfile.
Customization: When entered, this mode runs `comint-mode-hook' and
`inf-ruby-mode-hook' (in that order).
You can send text to the inferior Ruby process from other buffers containing
Ruby source.
`ruby-switch-to-inf' switches the current buffer to the ruby process buffer.
`ruby-send-definition' sends the current definition to the ruby process.
`ruby-send-region' sends the current region to the ruby process.
`ruby-send-definition-and-go' and `ruby-send-region-and-go'
switch to the ruby process buffer after sending their text.
Commands:
`RET' after the end of the process' output sends the text from the
end of process to point.
`RET' before the end of the process' output copies the sexp ending at point
to the end of the process' output, and sends it.
`DEL' converts tabs to spaces as it moves back.
`TAB' completes the input at point. IRB, Pry and Bond completion is supported.
`C-M-q' does `TAB' on each line starting within following expression.
Paragraphs are separated only by blank lines. # start comments.
If you accidentally suspend your process, use \\[comint-continue-subjob]
to continue it.
