# Warning
This project is no longer maintained in favor of using [Stategine](https://github.com/TheEmeraldBee/stategine)
as much more thought has gone into designing the systems for it. It supports entities **and** states, making it's implementation
much superior to this ones. As well, it is still maintained by me, and I am using it for a plethora of projects.

TLDR; This project is feature complete at this point, and there are much better alternatives, so I will only be updating this project when issues are sent.

The goal of this project is to simplify the requirements to make a good project using tui.
It removes boilerplate, and improves the developer experience by using the power of typemaps, and dependency injection

# Installation
Run the following within your project directory
```bash
cargo add widgetui
```
# Introduction

Widgetui is a wrapper over Ratatui's Crossterm backend which allows for powerful abstraction, and simplifies creating a good app within Ratatui.
## Why pick this over Ratatui?
Widgetui isn't meant to replace or undermine Ratatui. It is simply a wrapper. Without Ratatui, this crate would not exist, as well, you will still require Ratatui and Crossterm crates just to work with the apps.

**TLDR; Don't, use both together to improve developer experience, and build your apps faster!**

# Quickstart
```rust
use crossterm::event::KeyCode;
use ratatui::widgets::Paragraph;
use widgetui::*;

use std::error::Error;

fn widget(mut frame: ResMut<WidgetFrame>, mut events: ResMut<Events>) -> WidgetResult {
    let size = frame.size();
    frame.render_widget(Paragraph::new("Hello, world!"), size);

if events.key(KeyCode::Char('q')) {
        events.register_exit();
    }

Ok(())
}

fn main() -> Result<(), impl Error> {
    App::new(100)?.widgets(widget).run()
}
```

The above will create an application that will display an empty terminal window, then close once you press `q`.

This application, with many less lines, will render the same thing that Ratatui's Quickstart renders.

# Fun Facts
- I chose `WidgetFrame` because if I just used `Widget`, then you couldn't do the awesome
```rust
use widgetui::*;
use widgetui::ratatui::prelude::*;
```

- It took about 10 hours to get this project initially set up!
	- Much longer after I decided to add bevy system like widget methods.

- You used to have to take in a States struct, but in order to fix it, there is a lot of behind the scenes things going on!

- You can only use 11 states in the same widget!
	- If you need more, please add an issue with details on why, and we may consider adding access to more at once!
