might it be that what native image creates by default is an executable shared object lib ?

@sjfloat

I get the same behavior with the binary I downloaded from that site

This is all very, very strange.

Tomasz Godzik

@tgodzik

ok, if everything fails maybe you can use the latest version cs install bloop-jvm:1.4.8-90-77e59d70

I am still looking into some issues before releasing a new full version

bloop-jvm will also be the executable name in this case

Steve Jones

@sjfloat

That one works! Thanks.

On both machines. Thanks again.

Hi there. I have a minimal sbt build like

lazy val root = project.in(file("."))
  .settings(
    scalaVersion := "2.13.6",
    libraryDependencies += "de.sciss" %% "mellite-app" % "3.6.1"
  )

and I want to avoid that metals needs to run bloopInstall, i.e. I want to skip sbt altogether. Can I generate the equivalent of bloopInstall easily using the bloop-config library?

Hanns Holger Rutz

@Sciss

the website docs say I can use bloop.config.Config.File.write() but that method does not exist (bloop 1.4.8). How do I write a bloop config ?

Hanns Holger Rutz

@Sciss

seems it's now bloop.config.write(f, tgt)

@Sciss

I get "No build tool" from metals if I run :MetalsImportBuild , and I only use bloop instead of sbt. Like workspace dir looks like this:

src/main/scala/snippet.scala
.bloop/snippet.json

where the contents of snippet.json is:

what am I missing?

@Sciss build import is not neccessary, you could be able to just connect to build server

Hanns Holger Rutz

@Sciss

@tgodzik thanks - with the help of Chris I got it working (there was an issue auto-detecting the "project root"). Very nice, and much faster than having to begin with an sbt build.

Hi All, I am learning zio and I am trying to do a very simple thing which i am not able to do it, kindly help me if someone can

import zio._
import zio.App
import zio.console._
import zio.clock._
import org.rogach.scallop._
import scala.concurrent.ExecutionContext.Implicits

object Main extends zio.App{

    def run(args: List[String]) = {

        def get_downloads(a: String, b: String) = {

            val prog = for{
                _       <- ZIO(println(a))

            } yield ()

            prog.exitCode
        }

        val product_idL = List("1", "2", "3")
        val feedL =  List("a", "b", "c")

        case  class ProductFeed(id: String, feed: String)

        val cross = product_idL.flatMap(x => feedL.map(y => (x, y))).map(x => ProductFeed(x._1, x._2))

        val runtime = Runtime.default

        val program: Task[Unit] = 
            for {

                _       <- ZIO(println("------line 1---------"))
                a       <- ZIO.foreach(cross)(x => Task.succeed(get_downloads(x.id, x.feed)))
                _       <- ZIO(println("------line 2---------"))                
            } yield ()

        program.exitCode
    }
}

I see the following output without error, I need to know why am not able to print my ProductFeed?

------line 1---------
------line 2---------

Debugging is not supported because bloop server is running on a JRE
I Installed VS Code with Metals - when I try to debug I get the above massage.
Where is the configuration to tell bloop where the JDK is?

Hi there, I've just installed bloop using coursier and I can't seem to get zsh completions to work

I found evidence to suggest that completions might be installed by using coursier. I also attempted to follow the instructions to add to my zshrc but I can't find my ~/.bloop folder

I'm on ubuntu

Any help greatly appreciated, thanks!

I am just started to use Scala Metals with VScode currently on Windows 10. The simple hello-world example is not working. I got following exception:

BSP connection failed in the attempt to get: DebugSessionAddress. Debugging is not supported because bloop server is running on a JRE C:\Program Files\Java\jre1.8.0_281 with no support for Java Debug Interface: 'JDI implementation is not provided by the vendor'. To enable debugging, install a JDK and restart the bloop server.

Can anyone tell me what to do with it?

Hey @Alexander770 you'll need to have a full JDK installed. Currently Bloop started with a JRE, which doesn't support debugging

I'd installed JDK 8 or 11, and then use the command in VS Code, "Metals Restart Build Server", which should restart Bloop and should then start with the JDK

Alexander770

@Alexander770

During the process I allowed VScode to install .jabba\jdk\adopt@1.11.0-11. It is not enough?

Chris Kipp

@ckipp:matrix.org

[m]

🤔 if Metals installed it, it should have been enough. You can also try to set your JAVA_HOME via the Metals Java Home setting

and then do the restart

Alexander770

@Alexander770

I restarted and it works. thank you very much.

I was using intellij for scala now I try VScode. It looks a bit weird to me.

Alexander770

@Alexander770

In VScode why pushing the button above doesn't run the code?

Alexander770

@Alexander770

The challenge. In the VScode I have a dev container based on datamechnics spark&scala image.
How I specify in Dockerfile my working directory so that Bloop will see is. Here is the error I receive:

Tomasz Godzik

@tgodzik

@Alexander770 there are some issues if a wroskapce is copied to a docker container since files in .bloop have local paths

I would delete it manually or reimport the build in that case

How does Bloop discover the main class? Can I query Bloop to give me all the Main classes (class which are child of App)

Ólafur Páll Geirsson

@olafurpg

@siddhant3s here's a command to query for a main class

❯ bloop autocomplete --mode=mainsfqcn --project=cli --format=bash
com.sourcegraph.lsif_java.LsifJava

replace cli with the name of your project

Siddhant Sanyam

@siddhant3s

Woah!

Thank @olafurpg
BTW, I know you hear this a lot, but Sourcegraph is sick!
