Coprocess api #170

Closed andrewchambers closed 5 years ago

andrewchambers commented 5 years ago 
(sh/coprocess ... ) -> {:job ... :stdin ... :stdout ... stderr ...}

e.g. Expose janetsh over network:

(let [proc (coprocess janetsh)]
  ($ nc -l < (proc :stdout) > (proc :stdin)))

Things like $$ can be implemented in terms of coprocesses.

To implement the coprocess api, we may need to make file descriptor types from shlib that are gcable and can't be closed twice.

I have decided for now, this is worse than an api for explicitly creating/closing pipes.
