Significant changes since v0.12.1

For users

• An initial version ofExplicitResultTypesfor 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 viaExplicitResultTypes.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 thatscalafixScalaBinaryVersion(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, soRemoveUnusedandOrganizeImports.removeUnusedcan 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, breakingforward & backward compatibility.See#2079to tell whether your rule(s) are impacted, andscalameta/scalameta#3913to understand the changes.
• Despite the support of the built-in ruleExplicitResultTypesfor 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#2041if you are curious about the current blockers and the next steps on that journey.

For tooling maintainers (scalafix-interfaces clients)

• To supportExplicitResultTypeson 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 toScalafix.fetchAndClassloadInstance()instead of the binary one. Seescalacenter/sbt-scalafix#430as an example of expected changes.

Significant changes since v0.11.1

For users

• Better Scala 3 support
  • OrganizeImports.removeUnused&RemoveUnused(with aknown limitation for unused function parameters) are now supported with Scala 3.4+
  • New flagOrganizeImports.targetDialectto control wildcard/rename syntax & curly braces stripping behavior (seedocumentation)
  • LambdaTypeandMatchTypeare 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.Interpolatenow always capture curly braces through a wrappingTerm.Blockwhen 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 thatTerm.Block
    • Such rules must be updated to work with Scalafix 0.12.x, ideally with logic handling both presence and absence ofTerm.Blockto preserve compatibility with earlier Scalafix versions
  • tree.pos == Position.Noneis no longer a reliable way to check whether a giventreecomes 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 ontree.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)

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:OrganizeImportsis now a built-in rule (https://github /liancheng/scalafix-organize-imports/discussions/215)
  • com.github.liancheng::organize-imports:0.6.0+37-596459afhas been merged as-is into Scalafix, soOrganizeImportswill keep running without any modification to.scalafix.conf
  • To get rid of the "Ignoring requested classpath dependencycom.github.liancheng::organize-imports:0.6.0"warning, simply remove the entry from thescalafixDependenciessetting 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 inScala 3.3.0,RemoveUnusedis 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(seeBasicPositionSuitechangesfor 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)

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 withOrganizeImportsv0.6.0:

[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 (includingOrganizeImports) will work just fine despite this warning as the breaking changes in 0.10.x are very limited.

For rule authors

• Compatibility considerations have beendocumented
• For this release, the following updates to Scalafix dependencies bring backward-incompatible changes
  • Scalameta 4.5.xbrings
    • API deprecations & removals (scalameta/scalameta#2591&scalameta/scalameta#2582)
    • a tree parsing update (scalameta/scalameta#2601,seetypelevel/simulacrum-scalafix#194 (comment))
  • metaconfig 0.10.0now relies on an inlinedmetaconfig-pprintto limit the impact of a breaking change incom.lihaoyi::pprint:0.7.0(seecom-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'sderive*macros (used for theconfiguration case classes) means that a recompilation is needed.
    • At runtime,scalafix-cli:0.10.xbringscom.lihaoyi::pprint:0.6.6so that configurable rules compiled againstscalafix-core:0.9.xcan run
    • However, note thatconfigurable rules compiled againstscalafix-core:0.10.xwill cause cryptic runtime failures withscalafix-cli:0.9.x,so you should reflect that by releasing your rule built againstscalafix-core:0.10.xwith a major bump, and ideally by adding documentation describing your compatibility matrix.
