Scala import multiple packages

Question

I've got some Scala classes and objects, in their own packages. Each package has a package object defining some implicits, so for example import com.foo.bar._ imports all implicits and classes from the bar package

What I'd like to know is, is there a way to define an "umbrella" import, say com.foo.all, such that

import com.foo.all._

is equivalent to

import com.foo.bar._
import com.foo.baz._
import com.foo.qux._
...

I can understand that this might be a little unclear, but if I we consider the case where I have a large number of my own packages, this would clearly be more concise.

Answer 1

The Scala way to import multiple classes/objects from the same package is:

import scala.collection.immutable.{Map, HashMap, etc}

Cool Scala only trick: aliasing/renaming

import java.util.{Collection => JavaCollection}

Answer 2

The shortest form I can come up is:

import com.foo._, bar._, baz._, qux._

For example:

import scala.collection.mutable._, PriorityQueue._, ArrayBuffer._

EDIT

Perhaps, you want to use only some particular things, as @alex23 pointed out, so you may write:

import com.foo.{foo, bar, baz}, bar._, baz._, qux._
