Adding `asker` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add asker

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

asker = "0.3.0"

The asker library will be automatically available globally. Read the asker library documentation.

For a complete guide, check GUIDE.md and examples

    use asker::ask::Regex;
    use asker::ask;
    use asker::ask::FieldSet;

    // This example demonstrates basic usage, and main features

    fn main(){
        let fields: FieldSet = vec![
            ("email", vec![""], Some(Regex::new(r".*@gmail.com").unwrap())),
            ("username", vec!["req: Must be only lower-case letters", "default:uglyoctopus"], Some(Regex::new(r"^\p{Ll}+$").unwrap())),
            ("Are you logged?", vec!["isbool", "id:islogged"], None),
            ("password", vec!["hidden", "confirm"], None),
            ("In which year were you born", vec!["id:birth","default:1999"], Some(Regex::new(r"^\p{Nd}+$").unwrap())),
            ("Do you agree to the Terms of Service?", vec!["id:terms", "isbool", "default:true"], None),
        ];
        let (mut f, mut b) = ask::ask(fields);

        println!("\nString results");

        for (index, value) in f.iter_mut() {
            println!("{} --> {}", index, value);
        }

        println!("\nBool results");

        for (index, value) in b.iter_mut() {
            println!("{} --> {}", index, value);
        }

        println!("");
    }
