v0.13.0

Significant changes since v0.12.1

For users

• An initial version of ExplicitResultTypes for Scala 3 is available.
  • Expect limitations and bugs compared to the Scala 2 version - please report issues when possible, with a compact snippet.
  • Scala 3.3 LTS and Scala 3.5 Next are supported out of the box. Experimental support for Scala 3.4 can be unlocked via ExplicitResultTypes.fetchScala3CompilerArtifactsOnVersionMismatch = true.
  • To try it, the freshly published Scala 3 version of Scalafix must be loaded:
    • If you use scalafix-cli, pick the Scala 3.3.x LTS artifact if your sources are compiled with Scala 3 LTS, or the latest Scala Next otherwise.
    • If you use sbt-scalafix, make sure that scalafixScalaBinaryVersion (deprecated in sbt-scalafix 0.12.1) is not set in your build.
    • A small change is required for other build tools (see below), so reach out to the maintainer of the Scalafix plugin if you keep getting the error "The ExplicitResultTypes rule needs to run with the same Scala binary version as the one used to compile target sources" after upgrading.
• Scala 3.3.4 exposes unused warnings to SemanticDB, so RemoveUnused and OrganizeImports.removeUnused can now be used on sources compiled with Scala 3.3 LTS (Scala 3.4+ was already supported since Scalafix 0.12.0).

For rule authors

• Scalafix is now cross-built & tested against the latest Scala 2.x patch releases (2.12.20 & 2.13.15), unlocking upgrades of your builds depending on scalafix-testkit.
• Scalameta was bumped from 4.9.3 to 4.10.1, bringing many bugfixes and a few features, as well as some tree hierarchy changes in the parser, breaking forward & backward compatibility. See #2079 to tell whether your rule(s) are impacted, and scalameta/scalameta#3913 to understand the changes.
• Despite the support of the built-in rule ExplicitResultTypes for Scala 3, scalafix-core is not yet published for Scala 3, so you should stick to cross-building for Scala 2.12 & 2.13 only. Check #2041 if you are curious about the current blockers and the next steps on that journey.

For tooling maintainers (scalafix-interfaces clients)

• To support ExplicitResultTypes on Scala 3 sources, scalafix-interfaces can and should classload the freshly published Scala 3 artifacts. You should therefore remove the fallback to 2.13 when targeting Scala 3 sources. Also, to better support Scala 3 LTS, the full Scala version should be passed to Scalafix.fetchAndClassloadInstance() instead of the binary one. See scalacenter/sbt-scalafix#430 as an example of expected changes.

v0.12.0

Significant changes since v0.11.1

For users

• Better Scala 3 support
  • OrganizeImports.removeUnused & RemoveUnused (with a known limitation for unused function parameters) are now supported with Scala 3.4+
  • New flag OrganizeImports.targetDialect to control wildcard/rename syntax & curly braces stripping behavior (see documentation)
  • LambdaType and MatchType are now fully supported
• JDK21 is now fully supported
• Script files (.sc) are now supported

For rule authors

• Scalameta was bumped from 4.8.10 to 4.9.1, bringing many bugfixes and a few features, as well as some behavioral changes breaking backward compatibility
  • Term.Interpolate now always capture curly braces through a wrapping Term.Block when parsed with scalafix 0.12.x (scalameta/scalameta#3594)
    • This may trigger false negatives for rules tested against 0.11.1 or earlier, which do not expect that Term.Block
    • Such rules must be updated to work with Scalafix 0.12.x, ideally with logic handling both presence and absence of Term.Block to preserve compatibility with earlier Scalafix versions
  • tree.pos == Position.None is no longer a reliable way to check whether a given tree comes from the input document, since trees built via quasiquotes with scalafix 0.12.x may now have positions (scalameta/scalameta#3450)
    • To avoid false negatives on Scalafix 0.12.x, check equality on tree.origin, ideally combining this check with the previous predicate to preserve compatibility with earlier Scalafix versions
• scalafix-testkit is now published for Scala 2.12.19 & Scala 2.13.13
  • Usage of API methods decorated via implicits trigger new fatal warnings for rules built with -Xsource:3 (#1949)

v0.11.0

Significant changes since v0.10.4

For users

• Breaking: dropped support for running Scalafix against Scala 2.11 sources (#1635)
  • If you run Scalafix against projects containing Scala 2.11 sources, keep using Scalafix 0.10.4
• New: OrganizeImports is now a built-in rule (https://github.com/liancheng/scalafix-organize-imports/discussions/215)
  • com.github.liancheng::organize-imports:0.6.0+37-596459af has been merged as-is into Scalafix, so OrganizeImports will keep running without any modification to .scalafix.conf
  • To get rid of the "Ignoring requested classpath dependency com.github.liancheng::organize-imports:0.6.0" warning, simply remove the entry from the scalafixDependencies setting key (or similar if you are not using sbt)
• New: added support for the latest Scala versions (3.3.0, 2.13.11, 2.12.18)
  • Despite the support for the -Wunused:* flags added in Scala 3.3.0, RemoveUnused is not yet supported on Scala 3 (see #1728 (comment))

For rule authors

• Breaking: dropped support for ScalaTest 3.0 in scalafix-testkit (#1662)
• Scalameta 4.7.8 (was 4.6.0)
  • Breaking: source positions of trees captured by the Scalameta parser have evolved in Scalameta 4.7.x; particularly, parentheses are no longer captured by expressions (see BasicPositionSuite changes for a comprehensive view of the changes)
  • Deprecations: as Scalameta tree fields evolve, versioned extractors should now be favored over historical constructor-like ones (https://scalameta.org/docs/trees/guide.html#with-versioned-constructor-like-matchers)

v0.10.0

Significant changes since v0.9.34

For users

Scalafix will now issue a warning when loading external rules built with a potentially non-compatible version of Scalafix. Until new versions of these external rules are published, it is therefore expected that you get that warning, for example with OrganizeImports v0.6.0:

[info] Loading external rule(s) built against an old version of Scalafix (0.9.31).
[info] This might not be a problem, but in case you run into unexpected behavior, you
[info] should try a more recent version of the rules(s) if available. If that does
[info] not help, request the rule(s) maintainer to build against Scalafix 0.10.0-RC1
[info] or later, and downgrade Scalafix to 0.9.x (x>=31) for the time being.

Note that most community rules (including OrganizeImports) will work just fine despite this warning as the breaking changes in 0.10.x are very limited.

For rule authors

• Compatibility considerations have been documented
• For this release, the following updates to Scalafix dependencies bring backward-incompatible changes
  • Scalameta 4.5.x brings
    • API deprecations & removals (scalameta/scalameta#2591 & scalameta/scalameta#2582)
    • a tree parsing update (scalameta/scalameta#2601, see typelevel/simulacrum-scalafix#194 (comment))
  • metaconfig 0.10.0 now relies on an inlined metaconfig-pprint to limit the impact of a breaking change in com.lihaoyi::pprint:0.7.0 (see com-lihaoyi/PPrint#72 & scalameta/metaconfig#154). External rules had no reason to directly use the PPrint classes, but the internal usage of PPrint in metaconfig's derive* macros (used for the configuration case classes) means that a recompilation is needed.
    • At runtime, scalafix-cli:0.10.x brings com.lihaoyi::pprint:0.6.6 so that configurable rules compiled against scalafix-core:0.9.x can run
    • However, note that configurable rules compiled against scalafix-core:0.10.x will cause cryptic runtime failures with scalafix-cli:0.9.x, so you should reflect that by releasing your rule built against scalafix-core:0.10.x with a major bump, and ideally by adding documentation describing your compatibility matrix.
