scala - import to all package member files (package scope) -

i have multiple class files in 1 package/directory. similar this:

file 1:

package model import same.library class file1class {}[...] 

file 2:

package model import same.library class file2class {}[...] 

etc...

being part of package model allows each member access package model-defined classes, wondering if there way extend imports, avoiding write import same.library in each file if library required in entire package?

i think it's not worth effort, "just science":

you can use package object trick:

define alias imported library whether it's object, type or function (inspired scala.predef):

package object test {   def pow = scala.math.pow _ } 

and these package object members automatically available without import in same package:

package test  object testit {   val r = pow(2, 3) } 

in similar fashion can use way of doing through implicits.

define transformation/operation library implicit:

package object test {   implicit def strtoint(str: string): int = str.length } 

use implicitly:

package test object testit {   val strlength: int = "abc" } 

implicits don't have placed in package object, see implicit resolution other places scala finds implicits.

one more option use function scope, or object scope in same way:

package test  trait library {   def dosmth: string = "it works" } object library extends library  object scope {   def libraryscope[t](codeblock: library => t): t = {     codeblock(library)   } } 

and use this:

package test  object secondtest {     scope.libraryscope { lib => lib.dosmth } } 

in 3 cases avoid using imports using them somewhere else once. these options don't make code more clear unless have special case.
