Scala Plugin for IntelliJ IDEA

I am eagerly waiting for this plug-in to get to the point where I feel confident doing production development with it.  Last time I tried a version of the plug-in, it kept my Java code from compiling, and I had to back out.  That was a couple of months ago, but now I am very confused about the status of this plug-in development.  Nothing new appears in the version history any more, and this overview page isn't updated, but new plug-in versions do seem to appear.  It would be tremendously helpful if someone could go through and update the version history, the roadmap, and perhaps some of the other summary information, to give us all a sense of where this development stands.

Here's my scala class :

___________________________________
class GisPoint(x1: Int, y1: Int)

___________________________________

From a java class, even though it compiles and works, I get a syntax error with "new GisPoint(10,10)". Idea underlines the arguments and says:
"GisPoint() in GisPoint cannot be applied to (int, int)"

Any idea? I use 8.1.3 with scala plugin 0.2.27245

Thanks

Running scala code on IDEA on my Macbook doesn't work very nicely, it seems!?! the "Edit Configuration" wizard opens up the scala console so I end up with a ">scala " prompt instead of the code being executed.. Is this a mac related bug?

Is this supposed to work with the Community Edition? I have #IC-90.96, and I am told that the plugin is "not compatible".

same version, same problems, suggestions?

Looks like the Scala plugin is not compatible with the latest Community Edition (v 90.193).

Scala plugin is not available in EAP 92.24 version, it is not shown in available plugins list...

I tested several versions of scala IDE+plugins recently and IDEA is best so far.
The only two things that upset me (and i suppose they both have the same reason) are:

• often IDEA doesn't show any errors and i see them when running compiler
• type inference is far from perfection: in the following simple example i'm getting 'No suggestions' when trying to get autocomplete after 'yield b.'
  object Test {
  def a(s: String) = Some(s)
  def main(args: Array[String])
  Unknown macro: { val x = List("1", "2", "3") println(for (y <- x; b <- a(y)) yield b) }

  }

You guys are doing really great work, but could you tell us what are you plans on the things i noted above.
Thanks in advance.

And also... I looked through the list of tickets in issue tracker and i'm not sure if i should make a new ticket or is it a known problem. Some issues look similar to my problems but not exactly the same.

Hi All,

 I am using Idea 9.0 community edition. The comparison page (http://www.jetbrains.com/idea/features/editions_comparison_matrix.html) states Scala is available for users of the community edition as a plugin.

 When I open the plugin window and search for scala, nothing appears, but when I do the same in Idea 9.0 Ultimate Trial, I can see the plugin appears. 

 Can anyone tell me how should I install the plugin in the community edition.

Thanks,

Hi,

I just tried out the scala plugin for IDEA (93.54) and I am not sure if this is a bug or a missing feature:

1) auto-compilation does not show me all errors. For example if I call a method with the wrong count of parameters, this willof course result in a compilation error. But the error is not shown immediately in the editor, like it would with java or groovy.

2) On manual project compilation, the errors are not linked in the editor. I only see them in the compilation output.

Regards,
Andi

How can I rename a file? In the project structure I see only the classes inside the file.

Is the plugin only compatible with Scala 2.8? When I set the Scala version to 2.7 I get the ClassNotFound exception.

OTOH, if I set the compiler to 2.8, I cannot build Lift project.

Any suggestions?

Thanks,

Hey, it appears that the Scala compiler is really slow compared to the java compiler. Is there any work being done to improve this?

Hello

Thank you for a great plugin Im look forward to each time you make and "official" release.
However I have a problem with attaching Doc and sourcecode to the scala libraries. It works fine for other libraries as scalatest.
Iam using latest EAP and release from 2th. april, however it has been a problem for a while.

Hi, plugin is cool fo sure, thanks for good work.

One thing i noticed, when editing file with 2 or more classes and "structure" subwindow is open, then i have "short editor hangs on changing text" issue, hanging disappears

when i close "structure" window.

when i set Use fsc to compile. I got these errors:

Scalac internal error:

Can someone delete the above comment? It's just spam. The person has posted the same comment on every Scala forum and blog he can find.

Hi,

I've just installed the scala plugin with IJ 9.02.
I can add classes/objects but whenever I want to compile a scala class nothing seems to happen.
When I run the app via the main-method I get the following error:

"Exception in thread "main" java.lang.ClassNotFoundException: ScalaTest"

In the "Project Structure" view I have "Scala" enabled under "Facets" and
the scala-compiler.jar & scala-library.jar enabled under "Libraries".

Any hints?

I have already posted the question. i am trying to begin my journey and hitting roadblocks on the way. is there any help to at least get started?

With the community edition i have the plugin seems to be behaving very crazy. 

Hi,

Preface to the issue what i am facing. This may not be the best place for this but i dont know where this go to either.

1) for 10 years i have been a windows user and developer on C# , C++, VB developer.

2) Recently switched on to a new shiny mac in order to find out why its better. and this brought a new oportunity for me to help me to learn Scala and Lift web.

3) Went ahead and started learning Scala from a book and when i went to the Scala website it said intelliJ has a Scala plugin.

4) Downloaded the Community Edition ( Scala plugin also ) but Scala wont work with Community edition.

5) Downloaded the EAP 11 installed scala plugin.

6) but the step by step guide is only for windows the paths and other details didnt find any tihing for getting started with scala for MAC can we have a wiki page dedicated for it please?

7) EAP licence says only for 30 day trial. Can we have a EAP account and password so that i can still learn scala using the IntelliJ EAP software?

The "nightly builds" link near the top right of this page still points to the IDEA X version.

It probably should point to http://confluence.jetbrains.net/display/SCA/Scala+Plugin+Nightly+Builds+for+Nika by now...
