Mill Customization

import header._

object core extends HeaderModule {
  override def license: HeaderLicense = HeaderLicense.Apache2("2023", "lewisjkl")

  // defaults to List("scala")
  override def includeFileExtensions: List[String] = List("scala", "java")

  // if you want more control, you can use the following instead of `includeFileExtensions`
  // This shows the default implementation, but you can make it whatever you would like.
  override def skipFilePredicate: os.Path => Boolean = path => {
    os.isFile(path) && !includeFileExtensions.exists(ext =>
      path.segments.toList.last.endsWith(s".$ext")
    )
  }

  // defaults to this.millSourcePath, change this to change where the header checking/creation starts
  // looking for files
  override def headerRootPath: os.Path = millSourcePath
}
