I've tried changing the JDK selection in the Preferences, but that seems to have no effect.

Hi, I’m trying out Scala 3 and it when I import a project, I don’t get any autocompletion for new keywords (though highlighting works) and indentation also doesn’t seem to work if I got bracketless.

I understood that Scala 3 was already supported in the latest version of the IntelliJ scala plugin. But what is the extent of that support? I tried looking up online if there is a list of known current issues but I didn’t find anything so far. Are the issues mentioned above expected?

An answer to @aerua:matrix.org 's question might be useful, I'm sitting on some weird behaviour that I might report as a bug if it's not already documented as such

@aerua:matrix.org , @jyoo980 What version of Scala plugin do you use? You may use IDEA 2021.2 EAP to try latest updates, they are not yet backported to the stable versions. We are trying to make optional braces as convenient as possible. If problems are still there please report a new issue

you found it :tada:

you can also enabledisable it from action search

@hmemcpy

Sweet! Can't live without my action search :)

Also, I'm using the classic IntelliJ shortcuts, so on macOS one needs to disable the damn "open man pages in Terminal" global shortcut first :)

The advantages of Scala 3 seem to have enabled the implementation of Code Completion in Intellij to be dramatically simplified! The new Scala 3 version is massively simpler than the Scala 2 version :

def codeCompletionSuggestions(ctx: CodeContext, editorContext: EditorContext, ref: ProjectRef) = Global.showFailAlert("Cannot Perform Operation. Too complex, sorry.")

Hi all, does anyone know if Intellij support click to see differences feature for any of the scala test frameworks?

I would like to be able t, lest say, compare two list of case classes and get click to see differences when test fails.

Is there any ETA on when Scala 3 support will be approx as good as Scala 2 in IntelliJ? Or at least reasonably complete?

Hi all, just sent a PR to upgrade the plugin to use sbt 1.5.3! Who is brave enough to check it? :P JetBrains/intellij-scala#590

Eric Peters

@er1c

is there an easy way to turn off certain scala compiler flags (like warn on discard units) only while using intellij's native compiling? using sbt shell works but you don't get the nice point/click on failed files/etc

2 replies

or turn off test compiling maybe?

Hi, what's the best resource to track IntelliJ Scala plugin progress on Scala 3 support?

Is there a way to explicitly mark a specific directory as excluded? In my project there's a web project that contains a generated .caches directory, and I want to mark it as always excluded (so it survives a re-import). Is there a way to do this with IntelliJ somehow? Perhaps, a .ignore file of sorts?

Good evening! Is there a way to disable automatic refactoring of _ to * (including replacing => with as) during optimize imports, when -Xsource:3 is enabled?

1 reply

Unfortunately we're still using an older version of scalafmt and it doesn't like the as in Scala2 sources.

I'm guessing that's more of a Tobias Kahlert question :)

What does Incrementally type do, and whether turning Zinc on help?

Hey, a question to the PSI experts: I have 2 ReferenceExpressions: _.get.foo and _.get. I want to rewrite it to _.foo. Is there a way for me to somehow "subtract" the qualifying reference?

8 replies

I mean, I can do something nasty with substrings, but I was hoping that the PSI had a util somewhere

hey folks, I'm having issues with Scala 3 autocomplete similar to ones @aerua:matrix.org has. Autocomplete kinda "works", but it does not suggest any methods available for classes or objects I am working with. Switching to Scala 2 fixes the issue. I am on Intellij IDE 2021.2 EAP CE with Scala plugin 2021.2.9.

Also, when I am trying to "go to implementation" of some third-party classes, it fails to perform operation with the message "Cannot perform operation. Too complex, sorry"

Is it expected behavior or my local configuration has some issues?

It is pretty widely known among previous IntelliJ scasla users, metals is your best bet btw for now.

Does anyone else see a lot of these messages as warnings in their sbt logs when using the IntelliJ Scala plugin?

Hi all, Intellij suppose to support HOCON out of the box with Scala plugin right?

^ this does not work for me. I uninstalled and installed the scala plugin again but still the same.

I don't see HOCON in the supported FileTypes as well.

Dmitrii Naumenko

@unkarjedy

HOCON is a separate plugin

Hi, I’m trying to improve SBT’s BSP server to tell IntelliJ about the SBT build itself. I need to debug intellij-scala to figure out a problem, but it has been a while since I’ve done that.

I’m getting this error importing the SBT project:

[error] (ThisBuild / updateIntellij) java.io.FileNotFoundException: https://d2s4y8xcwt8bet.cloudfront.net/com/jetbrains/intellij/idea/ideaIC/212.4321-EAP-SNAPSHOT/ideaIC-212.4321-EAP-SNAPSHOT.zip

It looks like any .java file in a sbt project is being highlighted with the Scala 3 compiler messages.

Hi, is mixing Scala 2 and Scala 3 not supported yet? I added a src/main/scala-3 directory and 3.0.0 to crossScalaVersions and sbt seems happy, but the plugin treats sources in that directory as Scala 2

Oh it recognizes Scala 3 if I set the main scalaVersion to 3.0.0, I can work with that
