Angularjs call custom directive of modular1 in modular2

Hi,
Can we call custom directive of myModule1 in myModule2?

//file1.js

var app=angular.module("myModule1 ",[]);

app.directive('mydirective1 ',function(){

 // template

});

//file2.js
call above mydirective1 in myModule2.

Var app=angular.module('myModule2 ',['myModule1 ']);
