Debugging live app


I’m relative new one to RoR, and I have one concern regarding debugging.

I’m looking for a way to debug live app. I can use breakpoints, but as
far as I know they allow me to inspect application state in particular
place in code. I can change this state, but I can’t see possibility to
do something like step/next in gdb… Am I right, or is some way to get
such feature?

Simple require ‘debug’ in irb to gain access to ruby debugger hangs
whole app ;-))

For me RDT plugin (which looks like it have such feature) is no
solution, since I’m working via SSH, and can not run Eclipse on
development server.

Witold R.
