Ask

A simple toolset for asking questions through the terminal.

Usage

```rust extern crate ask;

use ask::question::{MultipleChoice, OptionGroup, TraitQuestion, QuestionOption}; use ask::validate;

fn main() { let mut multiple_choice = MultipleChoice::new("What would you like to order?");

let answer_collections = multiple_choice
    .add_option_group(
        OptionGroup::new("Entrees")
            .add_option_by_str("Calamari".to_owned())
            .add_option_by_str("Buffalo wings".to_owned())
            .add_option_by_str("Shrimp".to_owned())
    )
    .add_option_group(
        OptionGroup::new("Main Course")
            .add_option(QuestionOption::new("Lobster".to_owned()))
            .add_option(QuestionOption::new("T-Bone".to_owned()).toggle_selected(None))//toggle the selected to opposite to what it currently is
            .add_option(QuestionOption::new("Burger".to_owned()).toggle_selected(Some(false)))
            .add_option(QuestionOption::new("Duck".to_owned()).toggle_selected(Some(true))) //set this option to be selected by default asking the question
    )
    .set_validation(Box::new(|answer_collection| {
            validate::group_options::selections_are_gtoe(& answer_collection, 0) &&
            validate::group_options::selections_are_ltoe(& answer_collection, 3)
        })
    )
    // .replace_continue_btn("CAN CONTINUE!!".to_owned(), "CANNOT CONTINUE!!".to_owned()) //can customize continue btn
    .send()
    .unwrap();


println!("");

// let answer_collections = multiple_choice.to_answer_collections(); //can pull the answer_collections at any time
for answer_sets in answer_collections.answer_sets{
    for answer in answer_sets.answers{
        println!("{}", answer);
    }
}
