Libraries and Frameworks

• lift Web Framework
  lift (formerly Scala with Sails) is a web development framework. lift runs inside a Java web container and uses the Scala programming language for coding. lift code is as clean and brief as Rails, yet performs 6 times faster and is multithreaded.
  • Team: David Pollak, Maciek, DavidD, SteveJ and Eric Torreborre. Source Repository: liftweb.
     
• Scalax - The Scala Community Library
  The Scala Community Library (Scalax) is a nascent project to develop a general utility library for the Scala language, as a companion to the standard library.
   

• Scalaz
  Scalaz (Scar-lah-zed) is a library written in the Scala Programming Language. The intention of Scalaz is to include general functions that are not currently available in the core Scala API.
  • Team: Workingmouse Pty Ltd.
     
• Scala/xml
  Scala/xml is a collection of XML tools for Scala, e.g. schema2src is a data binding tool, xquery2src translates XQuery to Scala, xslt2src translates XSLT to Scala, etc..
  • Team: Burak Emir.
     
• Scala-rel
  Scala-rel is a Scala library for mapping relational algebraic expressions in Scala to SQL queries.
  • Team: Ryan Daum.
     
• Specs
  Specs provides a BDD (Behavior-Driven-Design) framework for the Scala language.
  • Team: Eric Torreborre.
     
• Jiva
  Jiva is a Scala based Genetic Algorithms (GA) toolkit. It provides a robust set of GA components that can be used out-of-the-box to solve real problems.
  • Team: Lalit Pant.

• Scalextric
  Scalextric enables the use of Scala in multi-language applications, taking advantage of every framework strengths and libraries through web-services communication (e.g. XmlRpc).
  • Team: Gabriel Riba.
     
• Soletta
  Soletta is a Scala implementation of the Paterson and Hinze’s Finger Trees.
  • Team: Ross Judson.
     
• Combinator parser library for Scala
  The combinator parser library provides for easily parsing text into ASTs. Since version 2.6 of the Scala software distribution it is part of the standard Scala library as package scala.util.parsing.combinator.
   

Development Tools

• maven-scala-plugin
  The maven-scala-plugin is used for compiling Scala code in Maven.
  • Team: David Bernard. Requires: Java 1.5 or newer, Maven 2.0.7 or newer.
     
• JavaRebel
  JavaRebel has donated a free license to the Scala community. More information on this page of the lift website.
   

Program Testing

• ScalaCheck
  ScalaCheck is a Scala implementation of the QuickCheck library for Haskell. It tries to keep the look and feel of QuickCheck as much as possible, while being open for improvements and extensions that can ease the task of property-based, randomized testing of Scala programs.
  • Team: Rickard Nilsson. Requires: Scala 2.6.0 or newer. Documentation: User's Guide.
     
• Rehersal
  Rehersal is a testing framework for Scala, intended as an easier-to-use replacement for SUnit in the standard library.
