I believe there is *not* a general Expect-like tool for Racket, and I'm
not aware of anyone working on one.
I think it's feasible. I have done some application-specific
Expect-like stuff before in Racket (monitoring multiple streams,
efficient I/O, matching patterns, timeouts) for some closed-source
software, and Racket handled the mechanics of it fine, but I have not
generalized that.
As Eli pointed out when this question came up in the past, an
Expect-like tool also sometimes has to deal with Unix-like TTYs. If you
need to TTY control beyond stdio, you might need to use the Racket FFI.
For my "charterm", "roomba", and "vlc"(?) Racket packages, I was able to
avoid the FFI by exec-ing the Unix-ish "stty" program, but that can't do
everything TTY, and AFAIK it doesn't work on Windows.
