Scala ecosystem status

[andreisilviudragnea]

• Scala compiler performance issues
  • https://github.com/scala/bug/issues/12499 -> Tried to fix in https://github.com/scala/scala/pull/10168, but gave up.
  • Very slow type checking phase, no real effort in improving it at the moment. Previous tentatives: https://github.com/gkossakowski/kentuckymule and https://github.com/twitter/rsc. Both projects have been abandoned: https://gkk.dev/posts/status-kentucky-mule-faster-scala-compiler and https://github.com/twitter/rsc/pull/406
• Intellij Scala is buggy
• circe has only two maintainers: https://github.com/circe/circe/pull/1974. I also believe the project is evolving in a not optimal direction.
• ScalaMock is abandoned too: https://github.com/paulbutcher/ScalaMock/issues/429
• scoverage-maven-plugin seems abandoned too
• Nobody really uses Scala 3. Kafka Scala 3 support is abandoned so far:
  • https://github.com/apache/kafka/pull/11432
  • https://github.com/apache/kafka/pull/11350
• Monix is abandoned: https://github.com/monix/monix/issues/1701
• scalafix-maven-plugin is abandoned: https://github.com/evis/scalafix-maven-plugin/issues/84

scalafix-maven-plugin is abandoned: https://github.com/evis/scalafix-maven-plugin/issues/84

Actually, I support it. Though, sometimes I can react quite slowly. Not sure if I will invest into massive features and rewritings, because I don't use Maven at work anymore (nowadays I use Bazel).

BTW, I think, that ZIO ecosystem is quite amazing, and isn't abandoned at all =) Maybe it's time to move to ZIO.

Scala compiler performance issues

They are doing fixes as we speak: https://github.com/scala/scala/pull/10258

Intellij Scala is buggy

Try https://scalameta.org/metals/

circe has only two maintainers: https://github.com/circe/circe/pull/1974. I also believe the project is evolving in a not optimal direction.

Looks good to me, but your are welcome to try https://github.com/plokhotnyuk/jsoniter-scala instead. @plokhotnyuk is very active.

ScalaMock is abandoned too: https://github.com/paulbutcher/ScalaMock/issues/429

Mocks are evil. Literally nobody is using them these days. Just write your own stubs.

scoverage-maven-plugin seems abandoned too

Try https://github.com/scoverage/sbt-scoverage. Works really good for me.

Nobody really uses Scala 3. Kafka Scala 3 support is abandoned so far:

Lichess is one of the prominent projects using Scala 3 and being happy about it: https://lichess.org/@/thibault/blog/lichess--scala-3/y1sbYzJX

Monix is abandoned:

Try Cats Effect instead. Same stuff.

scalafix-maven-plugin is abandoned: https://github.com/evis/scalafix-maven-plugin/issues/84

Just stop using Maven. Use sbt. It is really good these days. Nothing similar to what it was in the olden days. Try it.
