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 3.4.0
  • 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.

v0.10.0-RC1

Significant changes since v0.9.34

For users

When loading external rules, Scalafix now verifies whether conditions are held to guarantee compatibility. It will therefore prevent rules built with a future version of Scalafix to be loaded, and issue a warning when rules built with an older, potentially non-compatible version of Scalafix are loaded.

The latter means that you will see a warning when loading any external rule available as of today, 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.
