Question

Linux: Windows:

A Command Line Question Asker for Rust.

Easy to use library for asking users questions when writing console/terminal applications.

This package is passively maintained. Don't let the inactivity fool you issues and feature requests will be addressed. It is due to being a small focused library that just works so well nothing has had to be done.

Usage

Add question as a dependency in your Cargo.toml to use from crates.io:

[dependencies]
question = "0.2.2"

Then add extern crate question; to your crate root and run cargo build or cargo update && cargo build for your project. Detailed documentation for releases can be found on docs.rs.

Example

extern crate question;
use question::{Answer, Question};

fn main() {
    let answer = Question::new("Continue?")
        .default(Answer::YES)
        .show_defaults()
        .confirm();

    if answer == Answer::YES {
        println!("Onward then!");
    } else {
        println!("Aborting...");
    }
}

Examples can also be ran directly:

$ cargo run --example yes_no_with_defaults
    Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs
     Running `target/debug/examples/yes_no_with_defaults`
Continue? (Y/n) why
Continue? (Y/n) y
Onward then!
