[scala-tools] IDEA Scala plugin

[sanity]

I've been playing with the Scala plugin (and the Scala "power pack", a secondary plugin) in IDEA's new free community edition IDE.  I've got to say that it is impressive, rock solid so far as I can tell, with completion that works, and some neat refactoring tools too.

Not to discourage those working on the NetBeans and Eclipse plugins - I'm still most comfortable in Eclipse, and really can't wait for the Eclipse plugin to be robust, and have features comparable to those available for Eclipse's Java users.

But, if you need a solid featureful IDE plugin *today* in a free IDE, you need to try IDEA community edition.

I can't even get it to install. I downloaded the Community Edition
from jetbrains.org, then the Scala plugin, and I am told that the
plugin is "incompatible". Is there a trick to it?

Thanks,

Cay

Where/how does one specify which URL for IDEA to use for plugins?

No luck--that's the one that it downloaded, and manually installing
made no difference. It is labeled "incompatible". I realize the
community edition is a beta, so one must expect issues such as this
one, but I am wondering why it works for you guys.

I just hit the "update plugin" on the available plugins list and it brought the 3.0.75. But only on Maia.

Well, it brought it in for me too. And then labeled it as "incompatible".

Is "Maia" different from the community edition? The original
recommender said it works with the community edition.

I had the same problem with the 3.0.75 plugin. The nightly from '16
Oct 2009' seems to work fine with the community edition, though:

How does one specify where IDEA should get a plugin? I just seem to get a fixed list in the plugin manager. Downloaded and unzipped a plugin but do not know how to point IDEA at it.

Tried the Scala plugin in IDEA btw. Was not very impressed with it. It is quite rigid in its indenting behaviour. If you dislike opening braces at the end of code lines and prefer to put them on the next line this plugin is a nightmare.
The code completion works but is quite slow. It tends to append () pairs after calls to methods without parameter lists which makes code completion quite a pain to use.

I have to say that I never cared much for IDEA before so I may be to much Eclipsified...

[L Jantzen]

I did as follows (on ubuntu ):

1) cloned the git repo for the community edition: git clone git://git.jetbrains.org/idea/community.git idea
2) ant build
3) cd out/artifacts/
4) tar  xvzf idea-IC-90.SNAPSHOT.tar.gz
5) cd idea-IC-90.SNAPSHOT/bin
6) ./idea.sh
7) open plugin manager
8) download scala plugin
9) restart idea
10) open scala project
11) Profit

[Silvio Bierman]

That sounds plausible (and quite impressive) for Linux but I am running this on Vista. I downloaded IDEA CE and installed it. The only way to get the Scala plugin is then to use the Plugin Manager that will search no more than some predefined list of plugin sources. It comes up with the 2.7.x variant of the Scala plugin but that is no good to me. I can (and have) download(ed) the current build which supports 2.8 but there is no way to tell Idea where to look for it. Seems like the only option is to wait until the standard repo upgrades.

I find it hard to believe that the PM can not be redirected like the Eclipse one can. Seems so very inflexible that there must be a trick.

Look in Settings, under Updates.  You can add plugin hosts.  I've only
checked this on Maia, not on CE.

You can just extract it in the plugins folder.

Best,

Well, that worked great. IDEA listed it as available but not enabled. Just had to check the enabled flag and it works.

Thanks a lot.

[Silvio Bierman]

Well, not exactly. It worked for the same version of the plugin but the current build remains disabled and is listed in red meaning that it is incompatible with the current version of IDEA.

Hi.

I just want to remind, that excep plugin repository, actual Scala plugin versions may be downloaded from
http://www.jetbrains.net/confluence/display/SCA/Scala+Plugin+Nightly+Builds
where you may compare your IDEA version with the one supported by the last plugin build.
An here
http://www.jetbrains.net/confluence/display/SCA/How+to+build+Scala+plugin+for+IntelliJ+IDEA+from+scratch
we have some advices on how to build plugin and install it which is also applicable for nightly builds.

Cheers!

That is where I got the plugin build but I do not see any information on which IDEA version is supported is supported by which build.

Yes, I found that page earlier. But I skipped the building part since I can download builds from the previous page and the build process there is not very practical for a Windows user. I do not know what git is and I do not have an Ant version hat I can run from the command line, only Ants embedded in IDEA and Eclipse.

But the part about unzipping in the plugin folder that is mentioned there is what is failing here. IDEA sees the plugin but lists it as an incompatible version.

Is IDEA CE not the latest IDEA version and is that why the plugin does not match? I knew that CE is lacking some functionality (which I don't need) but was under the impression that it is a recent version.

Gr. Silvio

[Ilya Sergey (JetBrains)]

If the plugin version you have now is grayed in IDEA I'd recommend you to check its version (Help -> About in IntelliJ menu). There you may see the build number. The last stable one is 90.122 and the right column on the nightly builds' page contains this information about a compatible IDEA version.

Cheers!

Ilya

Now that I finished reading ``Programming in Scala," I wanted to go
ahead and have a good look at ScalaTest. I'm using Eclipse with the
latest nightly of the Scala IDE, which uses Scala library 2.8.0.r19360.
The version of the ScalaTest Maven artifact is 1.0-for-scala-2.8.0-SNAPSHOT.

This is my test class, and it compiles fine:

class MyTest extends AssertionsForJUnit {
        @Test
        def testEqEqEq() {
                val buf = new StringBuilder("ScalaTest is ")
                buf.append("fun!")
                assert(buf.toString === "ScalaTest is funx!")
        }
}

Naturally, the `===' comparison fails here, and when it does so I get this:

java.lang.NoClassDefFoundError: scala/collection/VectorLike
        at org.scalatest.Assertions$Equalizer.$eq$eq$eq(Assertions.scala:247)
        . . .

I looked around in my Scala library, and indeed there is no
`scala.collection.VectorLike', not even in any other package.

So what gives?

You need to compile ScalaTest with trunk. The snapshot used to compile
the binary you used is too old for the library used by the Eclipse
plugin for Scala.
