scalacheck-magnolia's Introduction

Scalacheck Magnolia

Generation of arbitrary case classes / ADTs instances with Scalacheck and Magnolia!

Why?

Because scalacheck-shapeless is good but too slow. Also this is much smaller and understandable, thanks to Magnolia!

Install

Just copy the files in src/main/scala to your project. It's 2 files, less than 60 lines in total! And you don't have to care about updating Scalacheck or Magnolia

How to use it?

import scalacheckmagnolia.MagnoliaArbitrary._
import org.scalacheck._

case class Example(a: String, b: Long)

val arbitraryExample = implicitly[Arbitrary[Example]]

println(arbitraryExample.arbitrary.sample.get)

scalacheck-magnolia's Issues

Example in README not working?

Hi @etaty,
thanks for this awesome library! One of my open source projects is heavily based on scalacheck-shapeless: I am rewriting it using scalacheck-magnolia to see if it can benefit from the performance improvements.

However, not even the example shown in the README seems to work:
val arbitraryExample = implicitly[Arbitrary[Example]]
doesn't manage to actually generate an instance of arbitrary.

I have written a test about it, you can have a look here - maybe I forgot some dependency or setting while copying things over....?

Also, do you have any plans to publish this library? I know it is only 2 files, but for maintainers using your library as dependency is not ideal because it would be more difficult to upgrade to a newer version or include any bug fixes.

Cheers,
D.

Release as artefact

It would be nice to be able to include this as a library dependency for a few reasons:

  • Conformity
  • No "invisible" dependency on scalacheck/magnolia
  • No confusion as to where to place files
