# TinkState# - Reactive State Handling for C# (and Unity!)

An uncomplicated library for dealing with mutable state in a nice reactive way.

[Documentation](https://nadako.github.io/TinkStateSharp/).

Features:

 - Lightweight and generic observable state primitives

 - Efficient binding mechanism with support for per-frame batching

 - Computed states with automatic update propagation

 - Asynchronously computed states with async/await

 - Out-of-the-box support for Unity with convenience helpers

 - Experimental support for Godot!

## Quick Peek

Here's a "hello world" teaser in Unity (source code below).

![](docs/helloworld.gif)

Source Code

```cs

using TinkState;

using TMPro;

using UnityEngine;

public class HelloWorld : MonoBehaviour

{

	[SerializeField] TMP_InputField nameInput;

	[SerializeField] TMP_Text greetingLabel;

	void Start()

	{

		// define piece of mutable observable state

		var name = Observable.State("World");

		// bind the state two-ways to an input field

		name.Bind(nameInput.SetTextWithoutNotify);

		nameInput.onValueChanged.AddListener(newValue => name.Value = newValue);

		// derive automatically updated observable value from it

		var greeting = Observable.Auto(() => $"Hello, {name.Value}!");

		// bind the auto-observable to a text field

		greeting.Bind(text => greetingLabel.text = text);

	}

}

```

## Status

**BETA**. Everything seems to be working and test coverage makes sure of it, but the code could use some polishing, naming review, performance audit. See also TODOs in the code.

## Thanks

It is a C# port of an excellent [Haxe](https://haxe.org/) library [tink_state](https://github.com/haxetink/tink_state) by Juraj Kirchheim ([@back2dos](https://github.com/back2dos)).
