funKTionale

Functional constructs and patterns for Kotlin

NOTE: Development of this project is frozen, as it will eventually be made obsolete by Arrow, which merges the functionality of funKTionale and Kategory. If you are not yet using funKTionale, we recommend you start with Arrow instead.

Functional Programming in Kotlin with funKTionale (video, presentation)

Maven (and Gradle)

You must configure your pom.xml file using JCenter repository

<repository>
    <id>central</id>
    <name>bintray</name>
    <url>http://jcenter.bintray.com</url>
</repository>

Then you can use any funKTionale module to your library

<dependency>
    <groupId>org.funktionale</groupId>
    <artifactId>funktionale-all</artifactId>
    <version>1.2</version>
</dependency>

How to contribute?

Rise your PR against Experimental module (funktionale-experimental). Once it gets approved I'll move it to a proper module
