  inquire is a library for building interactive prompts on terminals.

It provides several different prompts in order to interactively ask the user for information via the CLI. With `inquire`, you can use:

- [`Text`] to get text input from the user, with _built-in autocompletion support_;
- [`Editor`]\* to get longer text inputs by opening a text editor for the user;
- [`DateSelect`]\* to get a date input from the user, selected via an _interactive calendar_;
- [`Select`] to ask the user to select one option from a given list;
- [`MultiSelect`] to ask the user to select an arbitrary number of options from a given list;
- [`Confirm`] for simple yes/no confirmation prompts;
- [`CustomType`] for text prompts that you would like to parse to a custom type, such as numbers or UUIDs;
- [`Password`] for secretive text prompts.

## Features

- Cross-platform, supporting UNIX and Windows terminals (thanks to [crossterm](https://crates.io/crates/crossterm));
- Several kinds of prompts to suit your needs;
- Support for fine-grained configuration for each prompt type, allowing you to customize:
  - Default values;
  - Input validators and formatters;
  - Help messages;
  - Autocompletion for [`Text`] prompts;
  - Custom list filters for Select and [`MultiSelect`] prompts;
  - Custom parsers for [`Confirm`] and [`CustomType`] prompts;
  - Custom extensions for files created by [`Editor`] prompts;
  - and many others!

## Usage

Put this line in your `Cargo.toml`, under `[dependencies]`.

```toml
inquire = "0.9.4"
```

\* This prompt type is gated under a feature flag, e.g.:

```toml
inquire = { version = "0.9.4", features = ["date", "editor"] }
```

### Derive Macros

For enum types, you can use the `Selectable` derive macro from the `inquire-derive` crate to automatically generate `Select` and `MultiSelect` prompts:

Add this to your `Cargo.toml`:

```toml
inquire = "0.9.4"
inquire-derive = "0.9.0"
```

```rust
#[derive(Debug, Copy, Clone, Selectable)]
enum Color {
    Red,
    Green,
    Blue,
}

fn main() -> InquireResult<()> {
    let color = Color::select("Choose a color:").prompt()?;
    Ok(())
}
```
