promptt

promptt is a lightweight, interactive CLI prompts library for Rust. It supports text, confirm, number, select, toggle, list, password, and invisible inputs—ideal for building terminal wizards, config generators, or any step-by-step CLI flow.

Installation

Add this crate with Cargo:

cargo add promptt

Usage

Define a list of Questions (each with a name, type_name, and message), then run them with prompt(). Answers are returned as a HashMap<String, PromptValue>.

use promptt::{prompt, Question, PromptValue};
use std::io::{self, BufRead};

fn main() -> io::Result<()> {
    let questions = vec![
        Question {
            name: "username".into(),
            type_name: "text".into(),
            message: "What is your name?".into(),
            ..Default::default()
        },
        Question {
            name: "confirm".into(),
            type_name: "confirm".into(),
            message: "Continue?".into(),
            initial_bool: Some(true),
            ..Default::default()
        },
    ];

    let stdin = io::stdin();
    let mut stdin = stdin.lock();
    let mut stdout = io::stdout();
    let answers = prompt(&questions, &mut stdin, &mut stdout)?;

    if let Some(PromptValue::String(name)) = answers.get("username") {
        println!("Hello, {}!", name);
    }
    if let Some(PromptValue::Bool(yes)) = answers.get("confirm") {
        println!("You chose: {}", if *yes { "yes" } else { "no" });
    }

    Ok(())
}
