If you want to use Emacs:

C-x h (control-x then h) will mark (select) the whole buffer (file being
edited).

C-M-\ (control-(alt or escape)-backslash) will reindent the marked region. (The
whole buffer if you use the previous command.)

This will only work in emacs if you setup the ruby-mode written by Matz as
instructed in the file ruby-mode.el it's under misc or some place like that in
the disribution.  Emacs is a good editor though, somewhat problematic to learn.
