Possibly duplicate of #391.

I haven't had a chance to work with Scala 3 / Dotty before. Not sure what it takes and how are we from having scapegoat support that language.

[sksamuel]

I have Scapegoat working on Scala 3 in another repo.It's early days because we have to migrate every rule to new syntax since the reflection / compiler plugin stuff has changed considerably.

@mccartney greg happy to talk to you about this.

[mccartney]

Interesting. So is the plan to have a new project / fork, or will it possible to merge and maintain one code base?

[sksamuel]

Probably possibly. Is it desirable? For avro4s I've put Scala 2.12 2.13 in maintenance and on a branch and new features will go into Scala 3.

So based on the information above. The title doesn't do it justice as to work needed:

Please compile support for Scala 3.0.0

suggests it's about compiling/building/releasing a version. While in fact it's likely to be significant implementation effort.

@sksamuel is this available somewhere? I think it'll awesome to have even a few rules supported for Scala 3, rest of them might be added incrementally by interested people.

[kpodsiad]

@mccartney is there any ongoing effort with Scala 3 support?

[mccartney]

No. I don't think so. At least I am not aware

[sebarys]

is there any plan to support Scala 3/any place to track progress?

I've just checked https://docs.scala-lang.org/scala3/guides/migration/scala3-migrate.html dependency update and scapegoat plugin is blocking migration in my case:

[error]
[error] Incompatible Libraries:
[error] ("com.sksamuel.scapegoat" %% "scalac-scapegoat-plugin" % "2.1.6" % "scapegoat").cross(CrossVersion.full) (Full cross-version)

[saeltz]

No plan and no progress on the work @sksamuel started. It’s more or less a new library to be written. I suggest to use Scala 3 compiler linting instead.

[Johnnei]

I've been tinkering a bit with support for Scala 3 (as I want to move some of my projects to Scala 3 too), but the earlier comments are certainly right: Each inspection will need to be revisited to make compatible with the dotty compiler trees.

It will still take some more free nights to get it into a minimum viable state to propose it as an PR here.

I don't use Scala anymore, so I did not finish the migration.

Up on that, see issue #868 or my repo with a partial port (70 rules for now, working on more)
