WartRemover is a flexible Scala code linting tool.
Documentation for Wartremover is available here.
It's very useful to get the tree expanded by the Scala compiler,
rather than the original source. Adding the -Xprint:typer flag to
the Scala compiler will show code like the following:
// println("Hello world")
package $line4 {
object $read extends scala.AnyRef {
def <init>(): $line4.$read.type = {
$read.super.<init>();
()
};
object $iw extends scala.AnyRef {
def <init>(): type = {
$iw.super.<init>();
()
};
object $iw extends scala.AnyRef {
def <init>(): type = {
$iw.super.<init>();
()
};
private[this] val res1: Unit = scala.this.Predef.println("Hello world");
<stable> <accessor> def res1: Unit = $iw.this.res1
}
}
}
}Adding the generated code to an issue is very useful for debugging.
