Sometimes I'm stuck in a long loop when using binding.pry.
I can quit the loop by exit-program, but the command exit rails console also.

How do I dump Pry output to a file or Vim?
I have a Rails application, and I'm trying to export data, but directly through Pry because I only need to do it once.

Debugging in JRuby 9000
What is the best way to debug in JRuby 9000? Pry and Byebug are both MRI-dependent. All the JRuby info that I have found seem to be only for pre-9k, and are not working for my JRuby 9k setup.
