[lenguyenthanh]

The changes is here: lichess-org/lila-fishnet@1163f62

And the error is below:

info] Running scalafix on 18 Scala sources
[error] xxx/lichess/lila-fishnet/app/src/main/scala/http/MkHttpServer.scala:19:9: error: abstract givens cannot be anonymous
[error]   given Logger[IO] => MkHttpServer = new:

this pr in scalameta may fix this issue: scalameta/scalameta#4068

Thanks for the report. I'll double-check and tag a release tomorrow, but this should be fixed by #2140 in the latest SNAPSHOT, which will be referenced in https://scalacenter.github.io/scalafix/docs/users/installation.html#snapshot shortly.

thanks! I tried it fixed some but still at least some issue:

[error] {redacted}/lila-search/modules/app/src/main/scala/http.server.scala:20:9: error: abstract givens cannot be anonymous
[error]   given Logger[IO] => MkHttpServer = new:
[error]         ^

I think this is still scalameta issue, you can check the code here: https://github.com/lichess-org/lila-search/pull/392/files#diff-665a50336c22a54ed11c39141cc1649c40ec1cd141de9adc3754b95e000f7891R20

similarly, new context bound syntax gives an error:

[error] MyFile.scala:34:21: error: illegal start of declaration
[error]   def apply[F[_]: { Async, Tracer, Parallel }](
[error]                     ^^^^^

I will take a look at those, thanks!

def apply[F[_]: { Async, Tracer, Parallel }](

This seems to parse ok, so maybe it's just not working in the released version.

@ivan-klass could you confirm it works with the latest snapshot?
