Algebra unifies the basic algebraic type classes from Spire and Algebird. By targeting just these type classes algebra offers a package with no dependencies that works with Scala 2.10, 2.11, and 2.12, which can be shared by all Scala libraries interested in abstract algebra.

Algebra also interoperates with the Cats project. Algebra and Cats interoperate using the cats-kernel module.

getting algebra

Algebra supports Scala 2.10, 2.11, and 2.12, and is available from Sonatype (and Maven Central). In addition to the JVM, Algebra also supports Scala.js.

To use algebra in your own projects, include this snippet in your build.sbt file:

libraryDependencies += "org.typelevel" %% "algebra" % "0.6.0"

If you want to use Algebra’s laws, you can include those as well with this snippet:

libraryDependencies += "org.typelevel" %% "algebra-laws" % "0.6.0"

what we have so far

This repo has been seeded with most of the contents of spire.algebra, and has been modified to fit an initially-conservative and shared vision for algebraic type classes. Discussions over removals and additions should take place on the issue tracker or on relevant pull requests.
