Advanced semantic rules such as `ExplicitResultTypes` or [`ExplicitNonNullaryApply`](https://github.com/scala/scala-rewrites/blob/v0.1.1/rewrites/src/main/scala/fix/scala213/ExplicitNonNullaryApply.scala) using the presentation compiler via `ScalafixGlobal` require the build `scalaVersion` to match `scalafixScalaBinaryVersion`, and potentially the full Scala release used by Scalafix....
`-Wconf:` options were added in Scala 2.13.2. `warning-verbose` includes category and location in logging output, which is apparently being parsed to find the unused imports.

Currently in the documentation it shows that that you should install scalafix in the following way: ```scala addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.9.13") ``` However, `0.9.13` is the current version of...
When adding or maintaining integration tests via `scalafix-testkit`, it can be useful to dump the "actual" result of running the rules to the "expected" files, in the `output` directory. This...

Scala 2.13.2 / 2.12.11 / 2.11.12 SemanticDB 4.3.13 Scalafix 0.9.16 It looks like `scalac` is running dead code elimination early-on, so `-Wunused` / `-Ywarn-unused` does not raise warnings for *some*...
Reopening https://github.com/scalacenter/scalafix/issues/684. (/cc @dsilvasc) Is there a good reason for prohibiting `lazy val`s in abstract classes/traits? As per https://docs.scala-lang.org/tutorials/FAQ/initialization-order.html is seems to be fine.
## TL;DR Hit `scalafix.internal.v1.FileException` while testing a snapshot release (`0.3.0+9-86c91c86-SNAPSHOT`) of the [`OrganizeImports` rule](https://github.com/liancheng/scalafix-organize-imports/tree/86c91c8634ace360d417b7172288203375df8abf) against Metals master. ## How to reproduce 1. Checkout scalameta/metals@7b88c09 2. Apply the following diff: ```diff...
In scalafmt, the `onTestFailure: String` setting can be customized to print out a message on `--test` failure. See http://scalameta.org/scalafmt/#Other It would be nice if scalafix did the same, so that...
