SCCT( Scala Code Coverage Tool)

Srini — 2013-06-04T17:19:19

Hi,

I have implemented the scala code coverage plugin for the sbt build project 
and I was able to generate the code coverage 

now my question is:

1. In my project I have got some dependent libraries, how can I generate 
the code coverage for the there dependent libraries.

I could see one solution but this need project structure change:

1.  pull/get the other dependent projects under the main project, and run 
on that project.  *sbt scct:test

could you please provide any thoughts or idea/suggestions.

Thanks,
Srini.

Mailing list reminder: Scala-tools

Scala Mailing Lists — 2013-05-21T13:32:03

Welcome to the "Scala-tools" mailing list.

This automatic reminder is sent once a month to the list,
to keep subscribers up-to-date with the mailing list services,
and to help keeping the list on topic.

-------------------------------------------------------------------

The "Scala-tools" mailing list:

This list is devoted to all the community-contributed
tools and frameworks developed specifically for the
Scala language, as well as plugins and modules aimed
at integrating existing tools and the Scala system.


Examples are the Scala IDE plugins, sbaz, scalap, and
the many available editor plugins, but the
discussion can also cover sbt, Specs, ScalaTest, etc.

The set of topics that are discussed on this list
include both the usage of these tools, as well as
their development.

Whilst general discussion covering the Scala IDE for
Eclipse is welcome here, the main forums for user
support and for development are now hosted at
http://groups.google.com/group/scala-ide-user and
http://groups.google.com/group/scala-ide-dev.

Occasionally discussed on the list are also access
to the scala-tools.org website (maintained by the
Scala community and not by EPFL) and Maven
integration, as well as the Lift framework.

More rarely discussed, however, is the use of
general third-party tools that require no specific
integration effort in order to be usable with Scala.

If you are interested, for instance, in using some
specific Java library from Scala, your question is
more appropriately directed to "scala-user" instead.

Play2 v0.2.0 for Eclipse released!

Eclipse Scala IDE — 2013-05-16T07:16:46

The Scala IDE team is happy to announce a new preview release of the Play2 support plugin in Scala IDE for Eclipse!

In this release we focused on improving the route file support:

* code completion for every section of the route file
* rename refactoring for URLs
* hyperlinking to controller methods for Scala too
* a new quick-assist in Java and Scala sources to automatically add a controller to the route file
* and last but not least, better syntax highlighting out-of-the-box!

Check the wiki for details on all new features, or head over to the project documentation for all features.

Installation

The plugin is compatible with Play 2.1 applications, on Scala 2.10 or Java 1.5+. It should be installed on Scala IDE 3.0.0 for Scala 2.10, on both Eclipse 3.7 (Indigo) and 4.2 (Juno).

It is available through the Scala IDE ecosystem sites, the same as the ones used to install Scala IDE 3.0.0, under the "plug-ins" category.

Follow this guide for a step-by-step introduction to the development of Play2 application inside Scala IDE.

Feedback

The plugin was tested on a limited range of Play2 application configurations. If it seems to be incompatible with your setup, or if you notice other problems, please open a ticket with the relevant information or contact us on the Scala IDE mailing list.

Acknowledgments

The initial work was done by Amir Shaikhha. The effort was continued by the Scala IDE team and additional contributors: Iulian Dragos, Luc Bourlier, Mirco Dotta, Alden Torres and Vincent Munier.

Happy coding!

postgresql-async - async, netty based, PostgreSQL database driver (MySQL coming soon)

Maurício Linhares de Aragão Junior — 2013-05-09T02:50:51

Hello guys,

In case anyone else wasn't happy with the fact we couldn't talk to PG in an 
async way, this might be useful. I have released the first version of the 
postgresql-async ( https://github.com/mauricio/postgresql-async ) project, 
which aims to be a fully usable PostgreSQL database driver written in Scala 
on top of Netty.

The goal is not to replace JDBC at all (at least not at this point), but 
offer a simpler interface closer to the usual needs of "send a statement, 
get a result set". It already supports most of the PostgreSQL types and 
does both basic or prepared statements. Feedback on the Scala code, pull 
requests, bug reports, benchmarks are all welcome.

I have built a very simple play-2 app that uses it and deployed it to 
heroku. I have blogged the steps to do it in case someone is interested 
-> http://mauricio.github.io/2013/04/29/async-database-access-with-postgresql-play-scala-and-heroku.html

I have also started to work on a MySQL driver using the same general 
interface, it already does basic statements and I hope to add prepared 
statements support soon, so, if anyone would like to help with it, feel 
free do ping me over email or send PR's on Github. 

All code is available under the Apache 2 licence, so use it anywhere for 
any reason :)

Build iOS apps with Scala for fun and profit

Michael Bayne — 2013-04-30T01:09:34

I finally got around to making my "build iOS apps with Java" toolchain work
with Scala. I put together a simple demo app that shows all the moving
parts:

https://github.com/samskivert/ios-scala-demo

The executive summary is: scalac -> Java bytecodes -> IKVM -> CLR bytecodes
-> MonoTouch -> ARM assembly -> Apple App Store.

There are more details (along with the obligatory screenshot) in the README
in the above Github repo.

It's a whole lot of moving parts and sounds crazy on paper, but actually it
works pretty well. I've only used the toolchain to develop games, which
meant that I did not spend a lot of time writing code on top of the iOS
APIs, but they're reasonably usable (thanks to MonoTouch's hard work of
converting them all into C# APIs). With a few judiciously placed implicit
conversions, they could probably even be made comfortable.

Happy hacking,

Scala IDE 3.0.0-RC3 available now!

Eclipse Scala IDE — 2013-03-14T08:42:39

We are happy to announce the third release candidate for Scala IDE 3.0. Compared to RC2, we have four changes:

Fix for NPE in debugger variable view when using Eclipse Juno (#1001585)
Expanding variable in debugger resulted in NPE (#1001586)
Don’t add arguments templates for parameterless method’s completion (#1001591)
Return OK_STATUS from the semantic highlighting job when the editor is dirty. (#1001536)
RC2 was affected by a serious regression in the new Scala Debugger (debugging with the Scala debugger was simply not working). With this new RC3 the Scala Debugger is again fully operative.

We also upgraded to the latest Scala releases, 2.9.3 final and 2.10.1 final.

Installation

This release comes comes with 4 different flavors: It supports Scala 2.9 and 2.10, and Eclipse Indigo (3.7) and Juno (4.2). Head down to the download page and pick up the right update site for you!

Happy Scala coding!

Heads up: The deprecated option, -make, will been removed in Scala 2.11.

Jason Zaugg — 2013-03-06T08:53:58

The suggested upgrade is to use Zinc [1] (which is integrated into recent 
version of scala-maven-plugin and Gradle).

I noticed that this option is still used in a few test cases in 
scala-maven-plugin.

FFT libraries, system identification toolbox

sterg — 2013-02-10T16:12:16

Hi all,

I tested some FFT implementations and
it seems to me that the Oregon DSP based version of FFT runs very fast,
similar in speed with MATLAB.

I adapted it in the recent ScalaLab version.
Also, Numerical Recipes Java translation FFT performs well,
but Apache Commons is somewhat slower.

Opinions on which is the "best" Java-Scala FFT package?

Also, exists some good  "System Identification" library for the JVM?

[scala-tools] Scala By Example in Portuguese - Scala Através de Exemplos

Vinicius Miana Bezerra — 2013-02-04T11:10:21

Hello,

I am very proud to announce that Scala By Example is finally available in
Portuguese.
The latex sources are at: https://github.com/scala/scala-dist and the pdf
is at: http://www.scala-lang.org/node/274.

We did the best we could to find the most appropriate translation to many
new terms and we decide to keep some untranslated like 'trait' and 'mixin',
nevertheless there are many mistakes and improvements to be made, so I
would like to ask to those in this list that speak Portuguese, to please
help me improving this document, as it will be a valuable resource to many
Portuguese speakers to learn Scala. Any suggestions, questions and comments
are welcome.

I also take this opportunity to thank (in alphabetical order, so that no
one get jealous :) ):
   Antonio Basile - who teaches functional programming at Mackenzie
University and co-authored this translation.
  Heather Miller - who published the pdf together with all the Scala
documentation.
  Josh Suereth - who gave me the directions to get this integrated in the
scala-dist repository and patiently reviewed my pull requests written in
this obscure language called Portuguese :)
  Martin Odersky - for authorizing me to translate the book and for the
support and inspiration.
  To all members of the Scala Community - which directly or indirectly
helped me getting this work done.



Best regards,

Vinicius Miana

at integrating existing tools and the Scala system.


Examples are the Scala IDE plugins, sbaz, scalap, and
the many available editor plugins, but the
discussion can also cover sbt, Specs, ScalaTest, etc.

The set of topics that are discussed on this list
include both the usage of these tools, as well as
their development.

Whilst general discussion covering the Scala IDE for
Eclipse is welcome here, the main forums for user
support and for development are now hosted at
http://groups.google.com/group/scala-ide-user and
http://groups.google.com/group/scala-ide-dev.

Occasionally discussed on the list are also access
to the scala-tools.org website (maintained by the
Scala community and not by EPFL) and Maven
integration, as well as the Lift framework.

More rarely discussed, however, is the use of
general third-party tools that require no specific
integration effort in order to be usable with Scala.

If you are interested, for instance, in using some
specific Java library from Scala, your question is
more appropriately directed to "scala-user" instead.

Launching REPL in tomcat container

Sumit Kathuria — 2013-01-04T06:47:35

Hello 

I am trying to launch the scala REPL (2.9.2) in tomcat container and 
getting the following error

Failed to initialize compiler: object scala not found.Note that as of 2.8 scala does not assume use of the java classpath.For the old behavior pass -usejavacp to scala, or if using a Settingsobject programatically, settings.usejavacp.value = true.

I tried multiple solutions like settings.usejavacp.value = true etc., 
classpath setting but still getting the same error. Can somebody please 
suggest to resolve this issue?
I can also share the sample web project for demonstration. Surprisingly the 
same code base works in Jetty server.

Call for cooperation in creating Scala Wizards for numerical analysis tasks

sterg — 2012-12-27T11:30:17

Hi all,

from my experience in numerical computing, 
I think that the engineer should understand well the numerical
algorithm which is implemented in a scientific library,
but it is preferable to avoiding wasting time to understand details of
any one particular library.

Therefore, I consider the concept of Wizards that help the scientist to 
specify in a user friendly way the problem and thereafter they produce 
code targeting a particular library, can be very practical and useful.

I developed an ODE solver wizard at the context of the ScalaLab project
and it operates well.

Libraries existing at the core of ScalaLab that offer support for wide
number of numerical tasks are:
  a. the NUMAL library
  b. the Apache Common Maths
  c. the Numerical Recipes ed. 3 code, being translated in Java
  d. Linear Algebra only:  EJML, MTJ, JLAPACK, Colt

I call for cooperation at the task of developing wizard front-ends that
will produce library specific code to interesting scientists, with
Java/Scala background.
Perhaps that practical work can also produce and applied research
articles.

Use presentation compiler for syntax highlighting?

Rob N — 2012-12-26T22:34:45

Hi,

Can the presentation compiler API be used to syntax highlight Scala
code? I've started the attempt, but thought I should ask for
directions before going further. I'm not familiar with the compiler
source code or API. I have some code, something like:

    import scala.tools.nsc.interactive.{Global, CompilerControl,
Response}
    ...
    val cc = new Global(settings, reporter, "Test Project")
    val sources = List(cc.getSourceFile(fileName))
    dump(  cc.parseTree(sources(0))  )

I ran it on some tricky test input:

    val i = 1
    s"foo $i foo ${i + 1} bar"

The parse tree is helpful but not exactly ready-made for syntax
highlighting.  The node `s"foo $i foo ${i + 1} bar"` is marked as
Apply and Select nodes, and I haven't yet seen how to get the
boundaries between the string and expression parts.

Any suggestions on which direction to look, what types/methods will be
helpful?

thanks,
Rob
