expect module does not work with multiple prompts

[Edgars]

Hi

I have this task:

  tasks:
    - expect:
        command: /path/to/bash/script.sh
        responses:
          '#? ': '5'
          "[y/N]": 'y'

expect module correctly responds to first prompt, but not to second. It responds to second prompt with '5' when it should respond with 'y'.

When I enable echo=yes, I see:

...
"#? 5"

"[y/N]5"

...

You can easily reproduce it with bash script and two echo/read

I believe the problem is that pexpect treats all matches as regex.  You have specified '#?' which means the # is optional, effectively making the regex an empty string.

An empty string matches anything, so pexpect will send the response for '#?' for everything.

You probably want:

responses:
          '#\? ': '5'
          "\[y/N\]": 'y'

I think that should like help out.

Thanks a lot Matt, it worked. 

I was confused a bit because I saw that p/expect actually found the match (both of them), so I did not think that it could be regex issue

Thanks again

Hi,

I ran across a problem with expect response the same value to all prompt.

I have a task that execute a command and expecting four prompt the expect module response to the first prompt correctly but response to the 2nd & 3rd prompt with the same value from the 1st prompt.

 - expect:

    command: /path/to/the/script.sh

    responses:

     '.*?:$': '12345'

     '.*?:$': '12345'

     '.*?:$': 'xena-warrior'

     '.*?:$': '12345'

    echo: yes

All prompts have end of line ':'

From the output I can see the reponse '12345' in the third prompt and not 'xena-warrior'.

Any help would greatly appreciated,

David.

All of your "questions" are the same.  Because you are defining a hash/dict for responses, by providing the same key you are over writing the values.

If you need to respond multiple times to a question with different answers, this is not currently possible with the released version of the expect module but will be included in the next release.
