Python like package name aliasing in Scala

Question

I know that in Scala you can alias things inside package like that: import some.package.{someObject => someAlias}

Is there a way of creating alias for package name, not for classes/objects inside it ?

For example in Python you can do: import package as alias

You can alias a package name the same way you alias an object.

import scala.collection.{mutable => m}

val buffer = m.ListBuffer(1, 2, 3, 4)

buffer: scala.collection.mutable.ListBuffer[Int] = ListBuffer(1, 2, 3, 4)

Fun fact: You can also alias object methods this way.

import scala.collection.mutable.ListBuffer.{apply => makeBuffer}

scala> makeBuffer(1, 2, 3, 4)
res5: scala.collection.mutable.ListBuffer[Int] = ListBuffer(1, 2, 3, 4)

thanks, I don't know how I could have not tried it. How would you alias top package, in this case `scala`, is it possible ? – Michal Fudala Jan 30 '15 at 15:07
I'm not sure that you can. – Michael Zajac Jan 30 '15 at 15:10
there is *_root_* right at the top (sort of the root of the file system in case of ambiguity, see http://stackoverflow.com/q/687071/754787) so `import _root_.{scala => whatever}` should do the trick – Didier Dupont Jan 30 '15 at 15:23

I tried that, actually but it doesn't seem to work in the REPL. – Michael Zajac Jan 30 '15 at 15:25

import org.joda.time.{DateTime => joda}

Now you can use joda as synonym for DateTime

joda.parse("2014-12-23")
