Scala

Scala is a general-purpose programming language providing support for functional programming and a strong static type system. Designed to be concise, many of Scala's design decisions aimed to address criticisms of Java.

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

When I use Mirror of scala 3 to generate a typeclass list, the exception occurs. I know it's the hard limit of jvm of method size, but how can I circumvent this issue.

ps: When delete some fields of Data class it works, but any other solution?

Compiler version

sbt: 1.6.0

scala: 3.1.0

Minimized example

import scala.compiletime.*
import scala.deriving.Mirror

I just came across the fact that a Show[Throwable] exists.

  1. It is not wired up into import Scalaz._, one needs to import scalaz.std.java.throwable._
  2. It discards the stack trace entirely.

What's going on with this? :D
Is it OK if I fix both of these (for 7.2 and 7.3)?

steps

Using Scala 2.12.14 + SBT 1.5.x
Just include this import in your source

import java.time.temporal.ChronoUnit.MILLIS.{between => millisBetween}

problem

java.lang.NullPointerException

Description
It looks the Polynote doesn't support to configure Scala REPL like other notebook product.
For example, jupyter notebook support to configure Scala REPL such as

interp.configureCompiler(_.settings.outputDirs.setSingleOutput(replClassPath))
interp.configureCompiler(_.settings.Yreplclassbased)

Some configuration is hard-coded such as settings.Ydelambdafy.value is s
