Sending enter key event doesn't work with pexpect and survey #422

Open coinpayu opened 2 years ago

I am using python3's pexpect module to interact with survey.

How can I send an 'enter' key event to survey? I have tried sendline(), send('\n'), send('\r'), but all failed. It seems survey ignored them.

Hi, I don't have experience with pexpect, but Survey interprets either \n or \r read from stdin (from the terminal, to be precise, because Survey only works when stdin is connected to a terminal) as Enter key being pressed. https://github.com/AlecAivazis/survey/blob/93657ef69381dd1ffc7a4a9cfe5a2aefff4ca4ad/terminal/runereader.go#L104

If Survey ignores a keystroke that pexpect has sent, maybe something was wrong in the way pexpect was set up in your case?
