Termbox.jl (https://github.com/jgoldfar/Termbox.jl) is a wrapper for Termbox, a lightweight text-based user interface library. OSX and Linux are currently supported, and the low-level interface is complete enough to re-implement the demo from the original package (see test/outputexample.jl.)
I wrote this up yesterday for use in another project I'm working on (reporting results of a long-running computation in a nicer way,) but I'd be interested in feedback, ideas for a higher-level interface and how to effectively unit-test the package, etc. Regards, Max Goldfarb
