Scala 2.10 is an update of the scala programming language. This is a functional programming langage based on the JVM. This release contains language enhancements which may affected existing scala progjects of fedora users. This release support jdk-1.7 and contains support of the swing module in opposite of the official upstream release. This was done by a request of fedora users for a previous release on based of a patch from the upstream development repository. Additionally it's requires packages which doesn't available in fedora until yes.

[edit] Benefit to Fedora

Providing of the most current Release of Scala-2.10 which is a functional programming language based on the JVM. In opposite of the upstream release we want to offer support for the swing module on JDK-1.7. This swing module is an prerelease support which is not official released by the upstream distribution.

[edit] Scope

The new release of Scala introduces new minor changes of the language specification which may impact existing Scala projects. Additionally Scala 2.10 produces bytecode targetting jdk-1.7. Prior support of jdk-1.5 has been discontinued.

Currently, we provide a pre-release (jdk-1.7) swing module which is not currently included in the official Scala distribution.

The new release of Scala requires additional packages which are not yet included in Fedora. We need at least the following:

  • pax-swissbox
  • ops4j-base
  • ops4j-master

[edit] How To Test

1. Login as a normal user.

2. call the command scala.

3. Enter 'println ("Hello World")' on the scala prompt.

[edit] User Experience

[edit] Dependencies

We need some packages like pax-swissbox which are not already inteoducted in Fedora.
