It seems to work for me, though not consistently

it works as soon as you put the range into an intermediate val/var

Don't take me for the typical IntelliJ religious user (I use mainly Eclipse and Netbeans at work), but even with the recent improvements to Eclipse Plug-in, I still think that IntelliJ scala plugin is light-years ahead of Eclipse in terms of code completion and general features.
As for decreasing the compile time on IntelliJ I would recommend one of 3 things:

1. Use maven-scala-plugin (http://scala-tools.org/mvnsites/maven-scala-plugin/usage.html).
   I generally start a project with the scala-archetype-simple (http://www.mvnbrowser.com/artifact-details.html?groupId=org.scala-tools.archetypes&artifactId=scala-archetype-simple&version=1.3&tab=VERSIONS).
   IntelliJ will still provide the useful Scala Facet and pick the Scala Version from your maven dependencies.
   You can run scala:cc in a background shell. It will auto pick your changes and compile blazing fast. (Remember to disable Make Before Launch in you run configuration).

2. Enable FSC by checking Compiler -> Scala Compiler -> Use FSC.
    Start a Compilation Server in Run \ Debug Settings -> Scala Compilation Server (disable Make Before Launch).
    Then run your project as you would do normally.

3. Use SBT and integrated plugins (never tried, but here are some useful links: http://plugins.intellij.net/plugin/?idea&id=5007, http://stackoverflow.com/questions/4250318/how-to-create-sbt-project-with-intellij-idea, http://www.itdevspace.com/2011/04/setup-scala-with-sbt-in-intellij-idea.html). There are a lot of SBT enthusiasts that may help you further.

For me personally, option 1 works very well (almost as if I was working with a interpreted language).

If your are doing Web Development another tool to look at is JRebel (http://www.zeroturnaround.com/jrebel/). It is free for Scala usage.

Interesting, I didn't think about that. This syntax also works:

0.to(25)

When using the "space to do method calls" (I'm not sure what official
terminology is), the plugin is trying to do code complete on the
object "25". It can be argued that the IDE should "intelligently"
assume you want completion for the result of "0 to 25" instead of for
just 25, but maybe that's difficult to implement.

don't know much about maven except that it exists. i prefer 2, it's the
most simple way for me. and it works again. the last time i checked, it
was broken.

Hamster,

Since it has been fixed, I'm curious, in your opinion how to you think
IntelliJ + FSC compares with Eclipse in terms of compiling
performance?
Is Eclipse noticeably faster?

For quicker compile times on IDEA, start the "Scala Compilation Server" and select FSC in Settings -> Compile -> Scala.
I'm guessing Scala Eclipse does the same in the background wherein you don't have to manually start the compilation server.
There's a famous post on Stackoverflow where Martin Odersky explains why Scala compilation won't ever be as fast as Java and using compilation server's is the way forward.

I don't think starting the compilation-server as a separate manual step
is necessary any more these days. I just check the "Use FSC" in
Settings -> Compile -> Scala, no other action is taken, and IDEA starts
the compilation-server in the background. You can see the "FSC" process
using "ps" after compilation starts in IDEA.

Or are you experiencing even more speed-ups starting FSC manually as you
describe?

I still find compilation in IDEA slower than in Eclipse, but IDEA's
other excellent Scala-features makes it the preferred IDE for me. I
really don't need to compile so often as IDEA helps me reveal errors
quickly without the need to compile. In Eclipse compilation happens on
save (which I cannot understand anyone really wants) so I guess
compilation-times are more important to Eclipse-users. I've seen
Eclipse-users on my team struggle with almost anything in Scala except
compilation, so Eclipse seems to understand much less of Scala as a
language than IDEA does.

does the netbeans plugin use the scala compiler for displaying error messages so that there cannot be false positives or does it parse everything by itself like idea's plugin?
can it infer types for you?

I would be too, if I could get documentation displayed when using
autocomplete in the editor. It seems to display the docs for underlying
Javadocs OK, but says it can't find the docs for the Scala libraries.
Any tips?

You're absolutely right. I guess old habits are hard to dismiss. :D

No, not at all, I just didn't know I could skip the step.

Thanks for the confirmation, which rules out the cause just being my
stupidity :) The NB plugin situation seems kinda confused - there seem
to be different versions on different websites, and different Scala
versions seem to need different plugin versions.

I usually compile the plugin from  source. Regarding different versions of the plugin for different versions of scala, I think that's true... Everything broke when I migrated to scala 2.9, until I updated the plugin.

Since people here have been having success I decided to try using fsc
again from Idea. I am using Scala 2.8.1 and Idea 10.5 with Scala
plugin 0.4.1338.

I would prefer to use a Scala Compilation Server Run Configuration so
I can click on errors and have them navigate me directly to the line
of code.

I created a run configuration and ran it. The Run window opens with
the command

/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin/java
-Denv.classpath="%CLASSPATH%" -Denv.emacs="%EMACS%" -
Didea.launcher.port=7533 -Didea.launcher.bin.path=/Applications/Xena-
IU-107.481.app/bin -Dfile.encoding=MacRoman -classpath /Users/
ericpederson/.m2/repository/org/scala-lang/scala-compiler/2.8.1/scala-
compiler-2.8.1.jar:/Users/ericpederson/.m2/repository/org/scala-lang/

IU-107.481.app/lib/idea_rt.jar
com.intellij.rt.execution.application.AppMain
scala.tools.nsc.CompileServer

But then nothing else happens. Checking ps shows the process
running.

I tried using Settings->Compiler->Scala Compiler->Use fsc but that
does nothing. No process starts, no output is displayed.

Any ideas?

Just noticed something about the Eclipse plugin that bothers me
slightly. I cannot view Scala source code by adding a "source
attachment". I don't always view the source code of the library I am
using, but when I do, IDE integration makes it very convenient.

Does any of the other plugins do that?

Eric,

I tried using Settings->Compiler->Scala Compiler->Use fsc but that
does nothing.   No process starts, no output is displayed.

Any ideas?

Dumb question but, after you've started the compilation server and checked the option, have you run a Main method from inside the IDE or something?
Intellij don't build the project on save.

Some of the builds weren't working if you didn't start the server (At least I can report so for some OS X builds).
But I can attest that
IntelliJ Build 107.333 (Linux) and scala-plugin 0.4.1205 runs fine.

Cheers,

I tried that and didn't get very far. There are at least two sets of
conflicting instructions, and it wasn't clear where the source repo was
any more - at one point it appeared to have been in the NetBeans repo,
at another it looked like it has been in the java.net one. There was
also some confusion ove whether you needed to build the full NB source
or just install the NB module builder stuff. If you know the set of
steps that's needed to get it working properly, I'd be very grateful if
you could share them.

As a p.s. - Not only am I liking learning Scala, I'm also liking this
mailing list too - thanks to everyone for the responses :-)

Hi Anthony - 
You mean have I tried to run my app?   Yes.  Nothing happens with the CompilerServer either.
Actually I was expecting the CompileServer to compile files as they change - I guess that's not the case?   It kicks off a compilation when you Run or Debug?

Thanks,
-- Eric

Everything broke when I migrated to scala 2.9, until I updated the plugin.

I tried that and didn't get very far.  There are at least two sets of conflicting instructions, and it wasn't clear where the source repo was any more - at one point it appeared to have been in the NetBeans repo, at another it looked like it has been in the java.net one.  There was also some confusion ove whether you needed to build the full NB source or just install the NB module builder stuff.  If you know the set of steps that's needed to get it working properly, I'd be very grateful if you could share them.

As a p.s. - Not only am I liking learning Scala, I'm also liking this mailing list too - thanks to everyone for the responses :-)

The secret setting might be having scala in the PATH. If you read the
error-message/stack-trace I bet you se "cannot find 'scala'" somewhere.
Try starting idea from a shell where you know scala is in the PATH and
see if it makes any difference.

IDEA is not like Eclipse where it compiles on "save". You have to
compile manually using CTRL+F9 (make project) or CTRL+SHIFT+F9 (compile
current file).

Don't start any compilation-server manually, it isn't necessary. Just
check "Use FSC" and off you go. Ensure 'scala' is in you $PATH. Try
starting IDEA from a shell where you know 'scala' is in the $PATH.

IDEA is not like Eclipse where it compiles on "save". You have to
compile manually using CTRL+F9 (make project) or CTRL+SHIFT+F9 (compile
current file).

or just launch "sbt ~compile" in the embedded console or a separate window

I've built and installed it OK but I still get 'No document found'.
It's possible I haven't configured the Javadoc path settings properly in
the Scala platform definition - I have it pointed to the directory that
contains the index.html of the Scala doc tree.

Currently, nb scala only supports document which is from comments in source code.

Correct. But, for maven project, if you provide the source jar for  standard Scala components, it may works. I have not testes yet.

That's not determined by the Scala plugin. What are you trying to add a source attachment to, and how did it get into your project?

"View source" (mostly) works for me in Eclipse with the lift
source. Though sometimes I have to do a refresh on the workspace before
it works....

Source jars are added automatically by my gradle build script

/Jeppe

What I mean is that it would be nice if a plugin (on Eclipse, IDEA, or
Netbeans) can provide this functionality.

The jar files come from Casbah, added via SBT and sbteclipse. My guess
is that Eclipse treats Casbah binary as regular Java code and tries to
look for Java source code files. It may not be feasible to override
how Eclipse looks up source attachments to jar files, but it would
sure be really nice if there is an easy way to view Scala source code
for 3rd party scala libraries.

Perhaps I am doing something wrong. So you can open a Lift library
under the "Referenced Libraries" tree (in Package Explorer) and see
the Scala source code for Lift? Which version of Lift are you using?

For Maven project in NetBeans' scala plugin, if the source jar had been downloaded (by right clicking on Dependencies, then choose 'Download Sources'), you can CTL+click to open/jump to the referred source file.

Wait, did you try opening the jar's properties and checking or setting the attached source location?For instance, sbt-eclipse-integration --- an eclipse plugin --- creates its own classpath containers which are not editable by the user, so if it doesn't find the source you're stuck. But I would assume sbteclipse just adds the jars directly to the project definition, which means their source lookup should be editable. If your issue is that you would expect sbteclipse to specify the source path for you, then it's an sbteclipse question. For instance, the plugin for sbt 0.10 requires an extra parameter to add source information --- I think you do 'eclipse with-sources' or something (use tab completion to find out).
But again, I don't think it has anything to do with the scala plugin. There's nothing scala specific about attaching a source location per se. Of course the scala plugin gets involved, for instance to allow jumping to a definition or opening the quick outline, and it's possible that it would have a bug that would stop it from being able to open the source, of course (not that I know of such a bug).

Yup. I did. The source path can be modified and it is pointing to a

No, no, no. That's not what I am trying to get at. I think sbteclipse
did exactly what it advertised; I have no problems with it or the
eclipse plugin. What I am getting at is that even with the sourcepath
correctly set, I am not able to view the Scala source code for 3rd
party libraries.

No. I don't find fault with the Eclipse scala plugin for this. I am
wondering if I am the only one with this problem (perhaps through user
error) or if it is just the state of things. I am saying it would
certainly be a nice feature. I would definitely try out an alternative
IDE+plugin that makes this possible.

Okay, I don't know why I thought you were saying that the source path was not editable...Anyway for me it definitely works, so you should ask on scala-ide-user.
