specs2 2.3.11

Maintenance version


  • added await on Future[T : AsResult] to directly return a result #241
  • added a NoStdOutAroundExample trait to remove any console output during an example execution
  • added an onDistinctValues on contain matchers to specify that checks must apply to distinct values. Changed the implementation of allOf to be onDistinctValues(false) so that Seq(1) must contain(allOf(1, 1)) will not fail. For a match on distinct values, use Seq(1) must contain(allOf(1, 1)).onDistinctValues or Seq(1) must contain(eachOf(1, 1))
  • added the stacktrace of the caught exception in the failure message of a throwAn[Exception] matcher #250


  • matcher.toSet, matcher.toSeq, matcher.forall… are now deprecated since they can be expressed more clearly by using collection matchers


  • fixed contain matchers when using them with not
  • documented the use of argThat #240
  • fixed the or combinator on MatchResult when the first evaluation throws an Exception
  • fixed the AllExpectations trait when an evaluation throws an Exception
  • fixed the use of DataTables in mutable specifications when the datatable is successful and there are following expectations
  • added back the missing specs2.files object
  • using the arguments stacktrace filter for specifying a Result location. This allows custom matcher results to get a better location #254
  • fixed the counting of expectations when using and between results

scalatest 2.1.3

ScalaTest/ScalaUtils 2.1.3

ScalaTest 2.1.3 is a maintenance release for the 2.1.x series that includes a few enhancements and bug fixes. No source code using ScalaTest 2.0+ should break, but you will likely need to do a clean build to upgrade from 2.0. However, 2.1.3 is binary compatible with 2.1.0, 2.1.1, and 2.1.2, so you can just change the version number in your build to upgrade from earlier 2.1.x releases.

The list of enhancements and bug fixes below includes all changes since 2.1.0:


  • Added -z argument support to sbt integration, allowing test name wildcards to be specified when using sbt.
  • Enhanced Prettifier.default to handle scala.xml.NodeSeq and scala.xml.NodeBuffer.
  • Enhanced Prettifier.default to handle recursive class definitions like Fred extends Seq[Fred].
  • Refactored Prettifier.default to use stringPrefix for better performance.
  • Added -t argument support to sbt integration, allowing full test names to be specified when using sbt.
  • Disallow any suffix for Runner command line arguments that do not take a suffix. This will give a better error message if someone enters -z"database" instead of -z "database".

Bug fixes

  • Added missing must support to noException, a [SomeException] and an [Exception] matcher syntax.
  • Fixed StackOverflowError problem in Prettifier.default method when used with scala.xml.Node.
  • Fixed an owner chain problem in the assert macro (issue 276).

chart 0.4.0

scala-chart version 0.4.0 includes the following changes in the API:

  • new all you can eat import:

    import scalax.chart.api._

    mixin for chart apps:

    object MyChartApp extends App with scalax.chart.module.Charting {
      val data = for (i <- 1 to 5) yield (i,i)
      val chart = XYLineChart(data)

    more fine grained / a la carte imports in the module package (see API)

  • the views package has been dropped, instead, there is now a type class based approach for converting arbitrary data into the supported datasets, which are used by all high-level chart factories:

    val data = for (i <- 1 to 5) yield (i,i)
    val chart = XYLineChart(data)
  • the inversion in creating category datasets has now been fixed, i.e. the series or outer category is now correctly on the outside, e.g.:

    val data = List (
      "Series 1" -> List("bin1" -> 1, "bin2" -> 2),
      "Series 2" -> List("bin1" -> 3, "bin2" -> 4)
    val dataset = data.toCategoryDataset
  • support for markers on the domain and range axes:

    chart.plot.range.markers += 3.0
  • the itext dependency is now optional which is required for exporting to PDF, so you now have to include it explicitly as a dependency if you want to export to PDF:

    libraryDependencies += "com.lowagie" % "itext" % "4.2.1"
  • support for chart events based on Publisher / Reactor of scala-swing
  • revamped ToolTipGenerator and Label support, e.g.:

    pieChart.labelGenerator = PieLabelGenerator(value => value.toString)
  • builds are available for the latest stable 2.10.4 and 2.11.0-RC3; there will be a 2.11.0 release as soon as it gets out

Some of these changes and especially the cleanup of the old ways introduce source-incompatible changes. I hope this can be excused in the name of moving forward.

Please let me know, if you are using this library and have some particular legacy Java / JFreeChart code you want to turn into nice Scala-idiomatic code. I would be happy to take a look at it and try to support it in scala-chart.

For more information about scala-chart usage have a look at the README and at the API.

scala-chart is a Scala library for creating and working with charts. It wraps JFreeChart, much like scala.swing does with the original javax.swing package.

Skinny Framework 1.0.0

Skinny Framework is a full-stack web app framework built on Scalatra.
This is the first stable version release.

To put it simply, Skinny framework’s concept is Scala on Rails.
Skinny is highly inspired by Ruby on Rails and it is optimized for sustainable productivity for Servlet-based web app development.

What’s more, Skinny’s components are basically independent from Skinny app environment. If you prefer using only Skinny ORM, Validator module or else, it’s also possible. We hope Skinny components help developers that use other frameworks too.

If you’re interested in, see the official website below:
