# cassowary-csharp

![Build Status](https://github.com/lillo42/cassowary-csharp/actions/workflows/build-main.yml/badge.svg)

This is a C# implementation of the Cassowary constraint solving algorithm

([Badros et. al 2001](https://constraints.cs.washington.edu/solvers/cassowary-tochi.pdf)).

It is based heavily on the implementation for Rust at

[dylanede/cassowary-rs](https://github.com/dylanede/cassowary-rs). The implementation does

however differ in some details.

Cassowary is designed for solving constraints to lay out user interfaces.

Constraints typically take the form "this button must line up with this

text box", or "this box should try to be 3 times the size of this other box".

Its most popular incarnation by far is in Apple's Autolayout

system for Mac OS X and iOS user interfaces. UI libraries using the Cassowary

algorithm manage to achieve a much more natural approach to specifying UI

layouts than traditional approaches like those found in HTML.

This library is a low level interface to the solving algorithm, though it

tries to be as convenient as possible. As a result it does not have any

intrinsic knowledge of common user interface conventions like rectangular

regions or even two dimensions. These abstractions belong in a higher level

crate.

## Getting Started

Add the following to your csproj file:

```bash

dotnet add package cassowary-csharp

```
