Ruby

Coming from here: http://stackoverflow.com/questions/38248911/ruby-when-copying-streams-how-to-make-it-pass-input-characters

I don't know if the stdin is not flushing the special characters down the stack, or the leaf process stdout is not flushing upwards, but something is fishy in this:

#!/usr/bin/env require 'open3' Open3.popen3("expect -") do |i, o, e, t| Thread.start { IO.copy_stream(o, $stdout) } Thread.start { IO.copy_stream(e, $stderr) } i << "spawn bash\ninteract\nwait\nexit\n" Thread.start { IO.copy_stream($stdin, i) } t.value end #=> after executing, try "ls" and press tab
