Vote on Scala-Days 2011
The wiki page is here: https://wiki.scala-lang.org/display/SW/Scala+Days+2011 Sorry about the format, the choice of confluence plugins for this sort of thing is limited.

Re: Vote on Scala-Days 2011
Note, you'll have to be logged on for it to work.
If you had an account with trac, use that (the username will have been translated to lowercase)
Otherwise, create a new account via Jira: https://issues.scala-lang.org

SodaTest 0.1 Released
I'd like to announce the first release of SodaTest
(version = 0.1)
SodaTest (Spreadsheet-Driven Testing) is an open-source framework for creating Executable Requirements for Integration, Functional and Acceptance testing using Scala or Java.
SodaTest is an attempt to create an improved evolution of Ward Cunningham's Framework for Integration Testing, "FIT".
The two main differentiators are:
* the use of spreadsheets rather than HTML as an input format that is easier to edit and friendlier for business users;
* a simplified programming model that reduces the amount of Fixture code, is simpler to understand and encourages good practices.
There are a lot of other minor improvements, including sophisticated coercion of strings to strong types (value objects) and built-in JUnit integration.
To read more about the road that led to the creation of SodaTest and the path for the future, have a read of this blog entry:
http://grahamhackingscala.blogspot.com/2011/06/introducing-sodatest-spreadsheet-driven.html
If you want to see some screenshots, code samples, more about the motivations or just download the thing and play with it, go here:
https://github.com/GrahamLea/SodaTest
SodaTest is released under the Apache 2.0 licence.
You can clone it and build it yourself or get the 0.1 release through the Maven repo on GitHub. (See the blog for pom settings)
If you have the time to try it out, I'd love to get your feedback!
Cheers,
Graham Lea.

ScalaTest 1.6.1 for Scala 2.9.0 released
Hi All, I just released ScalaTest 1.6.1 for Scala 2.9.0+. This release includes quite a few enhancements, including enhanced support for property-based testing; two new style traits, PropSpec and FreeSpec; nested, specification-style output for all styles; and many other enhancements. (1.6 provides for Scala 2.9.0+ all the features 1.5 provides for Scala 2.8.1, plus a few more.) You can download a zip file here: http://www.scalatest.org/download Or grab it from scala-tools.org via: group id: org.scalatest artifact id: scalatest_2.9.0 version: 1.6.1 Or sbt: val scalatest = "org.scalatest" % "scalatest_2.9.0" % "1.6.1 Detailed release notes are here: http://www.scalatest.org/release_notes I expect no existing source code to break with this release, other than possibly through features that had been deprecated for several releases (most were deprecated in ScalaTest 1.0) that I removed in 1.5. You will need to recompile your tests, but should not need to make any other changes to upgrade (though it might be a good idea to fix any deprecation warnings prior to upgrading.) Please post on scalatest-users if you encounter any problems. ScalaTest 1.6.1 includes a few enhancements that were not released as part of ScalaTest 1.5 for Scala 2.8.1. These will be released for Scala 2.8.1 very soon as version 1.5.1. There was no ScalaTest 1.6 so that ScalaTest 1.5.x for Scala 2.8.1 will have a corresponding feature set to ScalaTest 1.6.x for Scala 2.9.0+. These blog posts previewed some of new features in this release: ScalaTest Property Checks Preview http://www.artima.com/weblogs/viewpost.jsp?thread=323644 ScalaTest PropSpec and FreeSpec Preview http://www.artima.com/weblogs/viewpost.jsp?thread=325537 Introducing the ScalaTest Shell: a DSL for the Scala Interpreter http://www.artima.com/weblogs/viewpost.jsp?thread=326389 Thanks.

ESBT Released
Dear Scala users, We're happy to announce ESBT, an SBT plugin for Eclipse. Features: - Based on SBT 0.10 - Allows SBT commands from the IDE (no need to use launch.jar) - adds dependencies to .classpath (using SBT's UpdateReport) - adds source paths to .classpath - resolves dependencies to workspace projects - excludes scala library when scala IDE is installed - non-intrusive: respects existing content in .classpath - graceful: no menu entries are shown when project doesn't contain build.sbt It can be installed from our update site: https://raw.github.com/scalastuff/updatesite/master The ScalaStuff team, Ruud Diterwich Alexander Dvorkovvy

Announcing Ozma: Extending Scala with Oz concurrency
Hi everyone,
I am pleased to announce Ozma, a conservative extension to Scala with Oz concurrency.
I have developed this language this year as my master's thesis, under the supervision of Peter Van Roy.
Oz (http://www.mozart-oz.org/) is a multi-paradigm language that has strong support for concurrent and distributed programming. It compiles to its own virtual machine (called Mozart) that supports dataflow synchronization and lightweight threads.
Ozma is an attempt at making the concurrency concepts of Oz available to a larger public. Scala seemed to me to be the best language for this experiment. Ozma implements the full Scala specification and runs on the Mozart VM. It can therefore be seen as a new implementation of Scala (actually it is yet another back-end for Scala, among other things). Ozma extends Scala with dataflow values (allowing tail-recursive list functions), declarative (deterministic) concurrency, lazy declarative concurrency, and message-passing concurrency based on ports. Almost all the concurrency examples of CTM (http://ctm.info.ucl.ac.be/) can be translated easily to Ozma. We can say that Ozma lifts the duality of Scala, namely the combination of functional and object styles, to concurrent programming.
The source code, and all the necessary information to download/compile/try it are available on GitHub:
https://github.com/sjrd/ozma
The text of the master's thesis is freely available at:
http://ks365195.kimsufi.com/~sjrd/master-thesis.pdf
If there are 2 pages you need to read, it is section 3.2, starting at page 28 of the PDF (numbered 22). This section shows, in a nutshell, all the features of Oz that I added to Scala: tail-recursion for list functions, dataflow values, streams, lazy execution, and ports.
Ozma has been announced on Lambda the Ultimate (see http://lambda-the-ultimate.org/node/4300). Comments welcome
I hope you find it interresting

Rex 0.7 Regular Expression Package Now Available.
I'm pleased to announce that Rex 0.7, a package for creating and using regular expressions without ever dealing with regex syntax, is now available at https://github.com/KenMcDonald/rex. In addition, there is a reasonably complete manual at http://kenmcdonald.github.com/rex/.
Rex allows you to build regular expressions with Scala constructors, operators, and methods. That means that your IDE's context-sensitive assist features can help with constructing regexes, and that many errors can be caught at compile time instead of at run time (which is when the regex is compiled).
Rex makes it easy to build and test small regular expressions, and then assemble them into larger regexes, which is standard good software engineering, but difficult to do with standard regexes.
Rex completely eliminates counting parentheses when extracting data from groups in matches. Instead, you create named groups within your patterns, and refer to these names to extract data from match results, eliminating one of the most common sources of errors in regular expressions.
I consider 0.7 to be the first version of Rex that is (I hope) ready for prime time. I have no intent to change the current API (other than additions, of course), though I would change it if someone came up with a _very_ good reason for doing so. Test coverage of the core functionality is pretty good, I believe. I do not yet have tests for the predefined patterns that are just wrappers of predefined Java patterns, such as "\p{Print}" Also, there is not yet support for defining patterns based on Unicode classifications--I believe this is possible, but don't know enough about Unicode to do anything at this point.
Feedback is welcome: Email ykkenmcd _at_ gmail.com.
Thanks,
Ken McDonald
