Clojurians Log v2

It would be very nice if there was joker.os API for chaining together some sub-processes with pipes; I'm working on a tool that fetches data over HTTP, which I want to pipe through jq and then optionally gron, and perhaps less. Right now, each subprocess runs individually, and the result is captured as a string that is passed to the next stage.

Also, is there a way to see if Joker's stdout is being piped?
