I’ve been doing a few things with Ruby which involve controlling and responding to long-running processes, where the Ruby-based ‘wrapper’ takes the task of automating something which is otherwise quite complex. Perhaps the best example is boxes, which uses a collection of Rake tasks to generate Vagrant boxes using Packer –– each build takes somewhere in the region of twenty minutes to complete. But, I wanted to be able to more closely control the output (hiding much of it from view)...
