Requestty

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

toml [dependencies] requestty = "0.1.0"

``rust let question = requestty::Question::expand("overwrite") .message("Conflict onfile.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)); ```
