Survey forces me to use []survey.Question for every occasion about survey HOT 7 CLOSED

@frodgesh I'm not sure if I understand correctly but I'll try to answer you based on the question I can imagine that you're asking for;

Validator is just a function of form: func(ans interface{}) error , the ans is the answer given from the user by terminal and if the returned error is not nil then the answer is invalid and it asks again.

You can use it anywhere you like, remember they're just functions, the AskOne is just a helper which you can pass a nil on its third input argument if you don't want them.

You can use Validators all over the place, look the README.md example, it has a Validation: field on Question struct: https://github.com/AlecAivazis/survey/blob/master/survey.go#L28 but this doesn't limit you to use those functions in other places inside your project as well!

@frodgesh thanks for submitting another issue. I'm slightly confused what exactly you're asking - do you mind providing a code block for the API you would like to see?

from survey.

@AlecAivazis, sorry about my explanation. I'm just asking, if it's possible to use validation above the AskOne.

from survey.

@kataras, I don't even know, how did I pass away the third argument, sorry for my clumsiness. And what about using Transform field in the helper's function?

from survey.

Thanks for helping out @kataras, I hope this clears things up for you @frodgesh.

I was just thinking about whether or not we wanted to include a Transformer as an arg to AskOne. Since Transformers are just normal functions, you can perform the transformation on the variable after calling AskOne.

FWIW, i opted to not add it as an arg to AskOne to avoid breaking the top-level API.

No problem, yes I didn't add those on AskOne for the same reason, although I think that AskOne should be avoided because we can't add many input arguments as struct fields on the Ask(...,Question)

@kataras, you said the exact reason, why did I open the issue.
