Ruby - Calling commands and interact with shell in Windows environment

问题

I am running an .exe file in the command line from a Ruby script that asks the user for a Yes/No response. I would like to know how the user can interact with it in Windows environment.

I have tried all the possible options: system, backticks, %x(), Open3, Open4... and none of them work.

Some posts ([1], [2]) resolve the issue using PTY, but as to my knowledge there is no implementation of the PTY module in Windows. Any other idea?

回答1:

Seems this is working under Windows too

pipe = IO.popen('your.exe', 'w+', :err => [:child, :out])
@pipe.each_line do |line|
  if /pattern matching question/ =~ line
    break
  end
end
pipe.puts('Yes')
# another test can be here
pipe.close

Wise to use with https://ruby-doc.com/stdlib/libdoc/timeout/rdoc/Timeout.html
