    @jastice It works! Thanks a lot.
    Hello everybody. In Scala 3 package objects are deprecated and hence all kinds of definitions can now be written at the top-level. There may be several source files in a package containing such top-level definitions, and source files can freely mix top-level value, method, and type definitions with classes and objects. However IntellijIDEA CE still doesn't recognize assets imported from such source files into other source files and even in same package (which does not require importing), until the sources are compiled. Is there any way to fix wrong error highlighting due to unidentified imported assets?

    Hey guys, wasn't sure if this is the appropriate place or the general IntelliJ channel is.

    I'd like to disable automatic insertion of quotes after typing '=' inside an inline XML tag. Neither the HTML Smart Keys setting for this (https://www.jetbrains.com/help/idea/settings-smart-keys.html#smartkeys_html_css) nor the corresponding HTML Code Style setting (https://www.jetbrains.com/help/idea/settings-code-style-html.html#ws_html_settings_editor_code_other) seem to work for Scala.

    There don't seem to be any equivalent settings in the Scala submenus.

    Some support forum posts where people have had the same issues with other languages in other IntelliJ-based IDEs:

    In each one of the above cases, there either was no solution or it's irrelevant to Scala

    After updating to the latest EAP version, compiler flags for Scala 3 are not recognized anymore (e.g. -Ykind-projector, -source, ...). There is no crossbuild. In module settings, everything is set to Scala 3.0.1. SBT command line works fine, but 'rebuild project' fails. "scalac: bad option: '-source' "

    If anyone has the same problem, I'll look to file a bug report

    We have a intellij plugin that depends on JetBrains/intellij-scala.
    sbt runPluginVerifier gives below verification error :-

    Full stacktrace can be found at : https://pastebin.com/d3cCrMax

    All functionalities of our intellij plugin are working fine.
    So, we are assuming, that we don't need any of the failed optional plugins from stack-trace.

    How to make intellij plugin verification passed successfully.
    Below is plugin.xml of our intellij plugin :-

    Found out that Dotty imports formatting with scalafmt are broken right now.
    It would be great to fix 'em alongside with SCL-19335.
    It's a pretty annoying bug...

    I'm having issues with Intellij IDEA syntax highlighting the value inside of the @newtype annotated case class... is that to be expected? Does anyone have any suggestions for how folks deal with this?
    Is that an annotation macro? I wasn't aware the plugin supported those
    Jeff May
    you can enable macro annotations in Scala 2.13 with the scalac option: -Ymacro-annotations
    obviously, the need for this library goes away in Scala 3
    as you can just use opaque types
    In Scala yes, but I don't think the plugin supports anything besides blackbox def macros in Scala 2
    Jeff May
    ok, so this is probably to be expected then
    I'm just curious if there is any workarounds I can use
    Actually, there's some code in the plugin's source for this macro specifically
    No idea if you have to enable it or what
    Jeff May
    that's interesting... maybe it just got out of date? I don't see a config for it.

    Why did autocomplete get so slow
    Yuriy Yarosh

    nn autocompletion broken for scala3 - doesn't pick the type after nn calls

    import software.amazon.awssdk.services.s3.S3Client
    val client: S3Client = S3Client // here's fine
        .nn // doesn't autocomplete at all after this .nn because loosing the underlying type

    nn is a scala3 not null call to translate Type | Null -> Type explicitly and enforce null safety at compile time (it'll still crash with NullPointerEx if it'll get one from Java, but meh)

    Metals picks nn's just fine.

    I've upgraded to the latest Scala plugin today, alongside the upgrade to IDEA 2021.2, and am having issues with my builds timing out. For some reason (historic), the "ICode" phase of one module in our project build takes ~5mins to complete - during this time, we see memory usage grow and shrink as the GC runs, so it's not "hung", just "really annoyingly slow". Unfortunately, with the latest Scala plugin, I now get a message saying "no response from compile server for 60 seconds" during this period, and the pluging attempts to fallback to a "local" compile - despite the fact the compile is still running on the compile server.
    Is there any way to extend this timeout?
    9 replies
    Or perhaps the better question - where can I set scala.compile.server.socket.read.timeout.seconds?
    In Scala REPL, how does one exit out of :paste? ^D doesn't seem to help.

    Hey there, in this small example, my export is turned into import in Scala3 in IntelliJ. I checked with scalafmt which is on my path, but it kept the export. Anyone experiencing the issue where export turns into import?

    import java.time.LocalDate
    class CalendarEntry(private val localDate: LocalDate, val name: String):

    May I ask a question about my problem?

    in the course of build of my files.. I got this msg [Error] C:\Codes\federationGradle\chisel3\core\src\main\scala\chisel3\Module.scala:7: object JavaConversions is not a member of package collection ]

    and I found that... my scala library version is 2.13.4 and it(JavaConversions ) is located in under 2.12.10.. so I tried to change my version.. but i couldn't include this version... I don't know why i can't change my dependency...

    I use gradle to build it up .. and my setting is as follows...

    Hello, I'm trying to enable package prefixes in my sbt project. It works well in sub-modules that use the src/main/scala layout, but it doesn't in Play sub-modules that use Play's app layout. The problem is that all library imports that start with com. are not recognized anymore (marked as red)
    1 reply
    My own project's package name also starts with com, so I guess the problem is somehow there
    Just wanted to see if there's resources being applied to Scala 3. I switched to nightly Scala plugin and it's still borderline unusable for Scala 3 (compared to Scala 2) Believe me I know that is a huge change and won't happen overnight – just wanted to check, should I report Scala 3 issues? Or are Scala 3 issues basically all the same "nothing works" issue at this point?

    Quick bug report (before I create a ticket for it):
    I have Scala 3.0.1 Maven project with latest nightly of Scala plugin. Project compiles fine both in IDEA and 'mvn package'. However, the instant I open a file in IDE - all of the types are marked red with "Not found: type XYZ" for every XYZ type in my project... Annoying as hell to be honest as I have to work with fully "red" project all the time.

    Is this a known issues that will be resolved soon?

    Scala 3 nightlies and local snapshot are at 3.1.0-RC1-XXXX. IJ paints everything red.

    Probably the part where the plugin selects the proper dialect according the Scala version expects 3.0.x or 2.xx only.

    Hello. I have an issue when I use accented character such as 'e' with a grave accent for test class, such as "class MillimètreSpec extends AnyFlatSpec with Matchers". If I try to run this test directly, it's ok. But if I try to run all the tests of the package, I have an error "java.io.UncheckedIOException: java.nio.charset.MalformedInputException: Input length = 1".
    After view investigation, it look like the system generate a file (e.g. @D:\Users\Luc\AppData\Local\Temp\idea_scala_test_runner6027035054604294689.tmp)that contain all the test to run, but the class name are not generated using "UTF-8" encoding.
    Is there a way to correct this?

    hi. i am working on an intellij scala extension for my macro library support. everything works fine however i need to manually add my ijext plugin to intellij scala extensions Even though i provided the intellij-compat.json for my macro library to force intellij to download and apply the ijext lib for macro support. i am using the latest CE edition and sbt-idea-plugin. any ideas why it does not work automatically? thank you

    i'm using the latest ultimate EAP (IU-212.5284.31) with the latest scala nightly plugin (2021.2.443). and the package search plugin is bundled with the EAP release. i can see the package search plugin settings in the settings window. i have a trivial "hello, world" scala 2.16.6 sbt project. and i've read https://blog.jetbrains.com/scala/2021/07/09/package-search-integration/, which says package search should work for scala. but for the life of me i can't get it to work at all. it makes me feel insane. thoughts/comments?
