Kala Common

This is a powerful set of Java core libraries that provide a series of easy-to-use abstractions and collections. If you have used Scala, it should be easy for you to get started with this collection library.

[!NOTE] This library is not production ready. When JEP 218 (Generics over Primitive Types) and JEP 401 (Value Classes and Objects) were delivered, we needed to redesign many APIs. (See #76 for more details)

Until Kala Common is production-ready, we do not recommend that you use this library for production.

Add Kala Common to your project

Maven:

<dependency>
  <groupId>org.glavo.kala</groupId>
  <artifactId>kala-common</artifactId>
  <version>0.82.0</version>
</dependency>

Gradle:

implementation("org.glavo.kala:kala-common:0.82.0")

Who is using Kala Common?

Although Kala Common is not yet production-ready, we are already using it in Aya Language.

We welcome others to try Kala Common for experimental purposes.

Note

The last version compatible with Java 8 was 0.70.0; The last version compatible with Java 21 was 0.82.0.

Building and running kala common now require Java 24.
