Adds explicit tuples around argument lists where auto-tupling is occurring.
To use this rule:
-Ywarn-adapted-argsfor Scala 2.11 and 2.12 (note,
-Yno-adapted-argswill fail compilation, which prevents scalafix from running). For Scala 2.13, use instead
- enable also
-deprecationto get warnings on insertions of
// before def someMethod(t: (Int, String)) = ... someMethod(1, "something") val c: Option[Unit] = Some() // after def someMethod(t: (Int, String)) = ... someMethod((1, "something")) val c: Option[Unit] = Some(())
Auto-tupling is a feature that can lead to unexpected results, making code to compile when one would expect a compiler error instead. Adding explicit tuples makes it more obvious.
Some auto-tupling cases are left unfixed, namely the ones involving constructor application using
case class Foo(x: (String, Boolean)) new Foo("string", true) // won't be fixed Foo("string", true) // will be fixed
This is a known limitation.
