@ericof are you planning to merge this anytime soon?

I like this idea but am leery of this implementation. It introduces syntax in the key name that must be interpreted. I think that a different implementation may be clearer, and allow for more than boolean dependencies.

For example:

{
    "trim-level": ["basic", "standard", "high-end"],
    "stereo": [
        {"case": {"trim-level": "high-end"}, "value": "xm-enabled"},
        {"case": {"trim-level": "standard"}, "prompt": ["am-fm-only", "xm-enabled"]},
        {"default": "am-fm-only"}
    ]
}

I'm not proposing that this is what an implementation should look like, only that the ability to ask follow-up questions is useful but should be considered in the context of more conditional control over the prompting.

Due to the age of this PR, I'm closing this.

@kurtmckee
I would like to add this feature. If you want any changes just say and I will work on it.
I think that my implementation was good, you could use more than a boolean parameter, but if you think differently just say and I will change

Hi @liortct!

I recommend pinging @ericof / @pydanny / @jensens in #1761 to hash out the implementation. As noted above, I think that dependent questions will be valuable, but it will be good to discuss a solution that allows for more than boolean conditions.

Hello @liortct, it would be awesome to have support for dependent questions, but I do agree with @kurtmckee about discussing the proper format to implement that.
Right now, I suggest we move back to #1761 and discuss it there.
