Announcing Scala.js 0.5.1

Jun 30, 2014.

We are excited to announce the release of Scala.js 0.5.1!

This version features bug fixes and improvements while remaining binary compatible with Scala.js 0.5.0. Therefore, Scala.js libraries may, but need not be republished with Scala.js 0.5.1.

Please report any issues on GitHub.

Improvements in the 0.5.1 release

For changes introduced in 0.5.0, how to upgrade, getting started etc. have a look at the 0.5.0 announcement.

Additions to the Java library

The following two are now implemented according to spec:

  • java.util.Date
  • java.util.Random

Wrappers for JavaScript Arrays and Dictionaries

Thanks to js.WrappedArray and js.WrappedDictionary (and some implicit conversions), js.Array and js.Dictionary can now be passed to Scala code that expects mutable.Seq and mutable.Map respectively:

def setHead(x: mutable.Seq[Int]): Unit = x(0) = 42
val array = js.Array(1, 2, 3)
println(array) // -> 42,2,3

Further, this allows to call methods defined on Map on js.Dictionary (foreach, map, filter, etc.)

Filter jsDependencies when executing JavaScript code

The new sbt setting jsDependencyFilter can be used to modify the dependencies used when running/testing:

jsDependencyFilter := (_.filter(_.resourceName != "jquery.js"))

The above would prevent “jquery.js” from being included by the sbt runners. See FlatJSDependency for fields that you can use.

Ordered testing output

When testing in the fastOptStage or the fullOptStage, test output sometimes appeared interleaved. This has been fixed this release.


Thanks to all the code contributors:
