AngularJS architecture: shared utilities across directives

What is the best practice for sharing functionality across multiple directives? Simple use case:

directive('colorInput', function() { // user inputs a hex value })
directive('stringInput', function() { // user inputs a string })

And lets say there's an HTML user assistance bubble that appears when the user focuses into an input. We might then have a function that positions the bubble relative to the input like so:

function setBubble(input, bubble) { // position the bubble }

Is there a way to maintain modularity and encapsulation? Or would this have to go into an angular service or the like? Thanks!

You should use controller instead. Checkout the section Creating Directives that Communicate in Angular Directive Guide. create a controller named inputGroupController that both your directives require it. Whenever user focus on an input, call baseInputController.setBubble(input, bubble). Take this Plunker: http://plnkr.co/edit/cUhxYmf9b3S1dsRjQXaG?p=preview
