Rewrite implicit derived values to scala 3 syntax. Missing a bundle/library? Please open a report it as a bug or submit a pull-request.
Configuration:
// default config
SemiAuto.bundle = [all]
// option to specify a bundle of rewrites
SemiAuto.bundle = [circe, doobie]
//Bring your own rewrites.
SemiAuto.rewrites = [
{ typeClass = "my.Decoder", derived = "Decoder" }
{ typeClass = "my.Encoder", derived = "Encoder" }
]Example:
// Before
case class Person(name: String)
object Person{
implicit val codec: Codec.AsObject[Person] = deriveEncoder
}
// After
case class Person(name: String) derives Codec.AsObjectRewrite implicit keywords to given and using. Please note that this rule might introduce some compile errors.
Example:
// Before
case class Message(m: String)
object Message {
implicit show: Show[Message] = ???
}
class Printer(implicit console: Console) {
def print[A](implicit showA: Show[A]): Unit = ???
}
//After
case class Message(m: String)
object Message {
given show: Show[Message] = ???
}
class Printer(using console: Console) {
def print[A](using showA: Show[A]): Unit = ???
}Rewrite dropped feature package objects
Example:
// Before
package foo
package object db extends doobie.syntax.AllSyntax
with doobie.Aliases
with doobie.postgres.free.Types {
def otherUsefulMethod[A](input: String): ConnectioIO[A] = ???
def otherUsefulMethod2[A](input: Int): ConnectioIO[A] = ???
}
//After
package foo
package db {
def otherUsefulMethod[A](input: String): ConnectioIO[A] = ???
def otherUsefulMethod2[A](input: Int): ConnectioIO[A] = ???
private object dbImpl extends doobie.syntax.AllSyntax
with doobie.Aliases
with doobie.postgres.free.Types
export dbImpl.*
}Rewrite dropped feature this qualifier from private and protected
//Before
package foo
class Foo {
private[this] val logger = getLogger
}
//After
package foo
class Foo {
private val logger = getLogger
}Rewrite dropped feature var foo: A = _
//Before
package foo
class Foo {
var state: Int = _
}
//After
package foo
class Foo {
var state: Int = scala.compiletime.uninitialized
}
