Scala Plugin - Inject TypeAlias Follow
Hi,
I want to inject a type alias in trait (based on Annotation). I could not find out if/how I can do it with one of the injectX() methods, that's why I'm asking.
The type alias is used as return type for a macro generated method.
trait Builder {
type T <: Builder
}
@Foo
trait A extends Builder {
def bar: String
}
There is a macro involved which will transform the code above to the following:
trait Builder {
type T <: Builder
}
@Foo
trait A extends Builder {
type T = A // <- this is the type alias to inject
def bar(s: String): T // <- type alias is used here
def bar: String
}
Best

In particular, there is a problem injecting something like:
type T <: A
This will result in a NPE when parsing the String.
