It thinks I am using underscores for imports even though asterisks has been used.
I am getting this issue time and again.
[error] ## Exception when compiling 16 sources to /Users/swoorup.joshi/personal/finflow-scala/trader/target/scala-3.0.1-RC1/classes
[error] scala.MatchError: AppliedType(TypeRef(TermRef(TermRef(ThisType(TypeRef(NoPrefix,module class finflow)),object common),WithEnv$package),WithEnv),List(TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class typesafe)),object config),Config), AppliedType(TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class actor)),object typed),Behavior),List(TypeRef(ThisType(TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class trader)),object actors),module class TradeEngine$)),type Command))))) (of class dotty.tools.dotc.core.Types$CachedAppliedType)
which is fixed on the RC1 version, but somehow props up every now and then.
And can be fixed by
clean; compile
btw does nightly metals still somehow use 3.0.0 compiler to compile 3.0.1-RC1 sources specified in sbt?
it shouldn't, no
I wonder there is some sort of cache created by the compiler that creates this invalid blob or something
does this happening when switching from 3.0.0 -> 3.0.1-RC1 or just from a fresh RC1 project?
and is on 3.0.1-RC1 early as when it was released :P
The
imports and objects within the console is just an continuation of the worksheet.
I have some time intensive thing going on, trying to think what is the best way of handling this, without writing a dedicated
main project.
is it that you just want quick repl responses?
and if so, does the quick evaluation in the worksheet itself not suffice? or how would dropping into the console help?
ahh, would maybe an ammonite script work better? so then you still have metals support in the script, but you can just run it with amm?
hmm, never tried ammonite.
in some ways they can be used similarly but most of the time
sbt console is used when you want to drop into a repl within the context of your sbt build. Ammonite has some of the same concepts, but is more used as either an alternative to the scala repl or as a script runner
This seems like what I want :P
Scala 3 support has been merged in Ammonite, not sure how stable it is. Almond will follow suit eventually, as the maintainer of it was indeed the one who merged Scala 3 support :)
You can potentially already run Scala 3 scripts with ammonite, just need the right version:
❯ cs launch ammonite --scala-version 3.0.0
Loading...

Hi! I have some problems with
For some classes it doesn't work, for example,
Is there some issue with it?
go to sources in scala 3.0 with vscode.For some classes it doesn't work, for example,
ConfigReader (but I can find it manually with #ConfigReader).Is there some issue with it?
@sinanspd: I don't believe there is an easy way to add that unless you'd add it into the actual scala syntax plugin https://github.com/scala/vscode-scala-syntax
Of course, you should be able to map that to whatever you want :)
WIth metals, I'm using sbt as my build server in an (experimental :-/) multi project setup,
I want to customise some integration tests
class WithDbFramework extends utest.runner.FrameworkIn an SBT terminal, the tests run fine.
If I click on the "ghost link" to run the test "in place" in metals, I get errors. The test looks for a test config file;
val confFile = new File("./modules/backend/src/test/scala/dev.conf")which apparently, it can't find ...
[ERROR] Uncaught exception when running tests: org.ekrich.config.ConfigException$Missing: ./modules/backend/src/test/scala/dev.conf (not found): No configuration setting found for key 'db'Would this be expected? Is it expected that an sbt terminal exhibits different behaviour to "metals runner"?
