JarCastingScalafix rules for Wither
@Wither
Run scalafix to turn this:
import ba.sake.kalem.Wither
@Wither
case class MyClass(x: Int, opt: Option[String])
into this:
@Wither
case class MyClass(x: Int, opt: Option[String], lst: List[String]){
def withX(x: Int): MyClass = new MyClass(x = x, opt = opt, lst = lst)
def withOpt(opt: Option[String]): MyClass = MyClass(x = x, opt = opt, lst = lst)
def withOpt(opt: String): MyClass = new MyClass(x = x, opt = Option(opt), lst = lst)
def withLst(lst: List[String]): MyClass = new MyClass(x = x, opt = opt, lst = lst)
def withLst(lst: String*): MyClass = new MyClass(x = x, opt = opt, lst = lst.toList)
}
Why ?
- more readable than named args
- autocomplete is nicer
- additional goodies for Options and Lists
How ?
Install scalafix as usual.
Add this to your build.sbt:
libraryDependencies += "ba.sake" %% "kalem-core" % "0.0.1"
ThisBuild / scalafixDependencies += "ba.sake" %% "kalem-rules" % "0.0.1"
and this to .scalafix.conf:
rules = [
Wither
]
