base on vʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality. # Vavr [](https://opensource.org/licenses/MIT) [](https://github.com/vavr-io/vavr/releases)  [](https://github.com/vavr-io/vavr/actions/workflows/ci.yml) [](https://codecov.io/gh/vavr-io/vavr) ```text ____ ______________ ________________________ __________ \ \/ / \ \/ / __/ / \ \/ / \ \______/___/\___\______/___/_____/___/\___\______/___/\___\ ``` Vavr is an **object-functional extension for Java that reduces boilerplate code and enhances code quality.** Vavr seamlessly combines object-oriented programming with the elegance and robustness of functional programming. It provides: * persistent collections * functional abstractions for error handling, concurrent programming * pattern matching * ...and more Since **Vavr has no dependencies** beyond the JVM, you can easily add it as a standalone .jar to your classpath. ### Stargazers over time [](https://starchart.cc/vavr-io/vavr) ### Maven Dependency <dependency> <groupId>io.vavr</groupId> <artifactId>vavr</artifactId> <version>0.10.6</version> </dependency> ### Gradle Dependency implementation 'io.vavr:vavr:0.10.6' ## Using Vavr See [User Guide](http://docs.vavr.io) and/or [Javadoc](http://www.javadoc.io/doc/io.vavr/vavr). ### Useful Maven Goals * Executing tests: `mvn clean test` * Executing doclint: `mvn javadoc:javadoc` * Executing code coverage report: `mvn -P ci clean test jacoco:report` * Create -javadoc.jar: `mvn javadoc:jar` * Create -source.jar: `mvn source:jar` ### Contributing Currently, there are two significant branches: - `main` (represents a stream of work leading to the release of a new ma version) - `version/1.x` (historical work that went into `1.0.0-alpha-3`, treat is as read-only - will be kept around for cherry-picking) A small number of users have reported problems building Vavr.
