I agree. Minimizing external dependencies (with a particular focus on the OS X experience) was a guiding principle of the project. I will probably use Ruby Readline (http://bogojoker.com/readline http://bogojoker.com/readline) to implement this. Another planned feature will likely require using Curses. It would be nice to reduce these two dependencies to one, but I'm not sure I'll start by reimplementing Ruby Readline in Curses.
