Question

I know a little bit about Emacs as I used it to write my thesis in AUCTex.

However, this time when trying to write some simple ruby program mostly to learn, I googled around for Ruby in Emacs and couldn’t found what I am looking for.

Based on what I read so far, I know that the Emacs(23.3.5) I am using has in-build ruby-mode, which should support basically syntax highlighting, auto indenting etc. But how about short-cut key for debug/run, something like Mode Compile?

Answer 1

I suggest using quickrun.el which is maintenanced by me.

quickrun.el is a extension to execute editing buffer.
quickrun.el supports many programming languages and markup languages, of course
it supports Ruby.

You download quickrun.el following URL.

https://raw.github.com/syohex/emacs-quickrun/master/quickrun.el

And you add quickrun.el following setting to your configuration file and evaluate it(or restart Emacs).

(add-to-list 'load-path "~/.emacs.d/elisp") ;; If you install quickrun.el to ~/.emacs.d/elisp
(require 'quickrun)

Now you can use following command to execute current buffer.

M-x quickrun

You can use compile current buffer(not execute).

M-x quickrun-compile-only

If you will often use quickrun command, you should assign key bindings, like following.

(global-set-key (kbd "<f7>") 'quickrun)
(global-set-key (kbd "<f8>") 'quickrun-compile-only)

Please see github page, if you know more information about quickrun.el.

Thanks
