Rustastic Prompt

rprompt makes it easy to prompt for input in a console application on all platforms, Unix and Windows alike.

rprompt is made available free of charge. You can support its development through Liberapay 💪

Usage

Add rprompt as a dependency in Cargo.toml:

[dependencies]
rprompt = "2.1"

See examples and docs at https://docs.rs/rprompt.

License

The source code is released under the Apache 2.0 license.


lib.rs:

This library makes it easy to prompt for input in a console application on all platforms, Unix and Windows alike.

Here's how you can prompt for a reply:

let name = rprompt::prompt_reply("What's your name? ").unwrap();
println!("Your name is {}", name);

Alternatively, you can read the reply without prompting:

let name = rprompt::read_reply().unwrap();
println!("Your name is {}", name);

If you need more control over the source of the input, which can be useful if you want to unit test your CLI or handle pipes gracefully, you can use from_bufread versions of the functions and pass any reader you want:

let stdin = std::io::stdin();
let stdout = std::io::stdout();
let name = rprompt::prompt_reply_from_bufread(&mut stdin.lock(), &mut stdout.lock(), "What's your name? ").unwrap();
println!("Your name is {}", name);
