Requestty

RustCI RustCI RustCI Crates.io License Documentation

requestty (request-tty) is an easy-to-use collection of interactive cli prompts inspired by Inquirer.js.

  • Easy-to-use - The builder API and macros allow you to easily configure and use the in-built prompts.

  • Extensible - Easily create and use custom prompts with a companion ui rendering library.

  • Flexible - All prompts can be used standalone or chained together.

  • Dynamic - You can dynamically decide what questions should be asked based on previous questions.

  • Validation - You can validate user input with any prompt.

  • Examples - Every prompt is accompanied with an example as well as other examples for more complex workflows

Usage

Add this to your Cargo.toml

[dependencies]
requestty = "0.4.1"

To ask a question:

let question = requestty::Question::expand("overwrite")
    .message("Conflict on `file.rs`")
    .choices(vec![
        ('y', "Overwrite"),
        ('a', "Overwrite this one and all next"),
        ('d', "Show diff"),
    ])
    .default_separator()
    .choice('x', "Abort")
    .build();

println!("{:#?}", requestty::prompt_one(question));

More examples are available in the documentation and the examples directory.
