Scalafmt in scala 3 dialect adds a new line after a `'` expression which changes behaviour of program about scalafmt HOT 6 CLOSED

Maybe the case is needed, so something like:

  private def printStatement: Unit = {
     stat match {
        case _ =>
          sb.line { _.append(s"val $fresh = ") }
          (true, List(Name(fresh) -> stat.pos))
      }

from the mdoc issue?

Looks like the same issue in mdoc https://github.com/scalameta/mdoc/pull/849/files

@mdedetrich thank you. scalafmt is very much context-sensitive, so could you please double-check that the code snippet you've provided formats incorrectly if put in a small file in its entirety?

your link doesn't load a relevant example for me (starts at the beginning of the diff and can't find anything that contains '{).

You seem to be right, with the following scalafmt doesn't remove the line break

object Test {
  val g = '{ ((r: R) => $upm.fromProduct(r.asInstanceOf[Product])).asInstanceOf[Any => Any] }
  (f, g, elemTpes)
}

Let me create a minimal reproducible sample

from scalafmt.

So this appears to be the quick minimal reproduction

object Test {
  Expr.summon[Mirror.ProductOf[U]] match {
    case  _ =>
      val g = '{ ((r: R) => $upm.fromProduct(r.asInstanceOf[Product])).asInstanceOf[Any => Any] }
      (f, g, elemTpes)
  }
}

The pattern match with case is necessary here
