`requestty` (request-tty) is an easy-to-use collection of interactive
cli prompts inspired by [Inquirer.js](https://github.com/SBoudrias/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](./examples) for more complex workflows

## Usage

Add this to your `Cargo.toml`

```toml
[dependencies]
requestty = "0.4.1"
```

To ask a question:

```rust
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](https://docs.rs/requestty)
and the [examples](https://github.com/Lutetium-Vanadium/requestty/tree/master/examples)
directory.

## Optional features

- `macros`: Enabling this feature will allow you to use the `questions`
  and `prompt_module` macros.

- `smallvec` (default): Enabling this feature will use
  [`SmallVec`](https://docs.rs/smallvec/latest/smallvec/struct.SmallVec.html)
  instead of `Vec` for auto completions. This allows inlining single
  completions.

- `crossterm` (default): Enabling this feature will use the
  [`crossterm`](https://crates.io/crates/crossterm) library for terminal
  interactions such as drawing and receiving events.

- `termion`: Enabling this feature will use the
  [`termion`](https://crates.io/crates/termion) library for terminal
  interactions such as drawing and receiving events.
