watch mode support #77
Description
Clear and concise description of the problem
My CLI has some commands which must be run in "watch mode". This means the process stays alive, and when some condition occurs, the handler is re-run. I was able to hack commander into doing this, although it was quite awkward. I'm not exactly sure yet what the ideal shape of things would be, but it's a use case worth supporting more natively.
Suggested solution
In commander, what helped make it possible was the existence of "hooks", as well as being able to attach arbitrary data to the ctx object. Will do some more digging into what I had set up, think about it, and post more details here.
