Vinegar (Java)

Vinegar is a set of small but highly reusable libraries. Vinegar libraries typically don't require any other libraries, but play nice with popular frameworks and libraries.

Getting Started

Add a Maven dependency on the vinegar library you need in pom.xml:

<dependency>
  <groupId>be.sweetmustard.vinegar</groupId>
  <artifactId>vinegar-pattern-matcher</artifactId>
  <version>0.1.1</version>
</dependency>

Features

Pattern Matcher

The Pattern Matcher Vinegar is inspired by JDK enhancement proposal 305. It brings Pattern Matching to Java in the form of a DSL. Here's an example of the Pattern Matcher Vinegar in action:

import static be.sweetmustard.vinegar.matcher.MappingCondition.is;

Function<Shape, String> matcher = new PatternMatcher<Shape, String>()
    .when(is(Circle.class))
        .then(c -> "Circle with radius " + c.getRadius())
    .when(is(Rectangle.class))
        .then(r -> "Rectangle with width " + r.getWidth() + " and height " + r.getHeight())
    .otherwise("Unknown shape");

String result = matcher.apply(new Rectangle(2, 5)); // Returns: Rectangle with width 2 and height 5
