angular provider $get doubts

I have some doubts about providers. Can someone explain me why I cannot access from the controller the "setText" provider function? I can only access functions inside the $get block.

var myMod = angular.module('myApp', []);

myMod.controller("mainCtrl", [ "$scope","greeting", function($scope, greeting){
    greetingProvider.setText("Hi, ");
}]);

myMod.provider('greeting', function() {
  var text = 'Hello, ';

  this.setText = function(value) {
    text = value;
  };

  this.$get = function() {
    return function(name) {
      console.log(text + name);
    };
  };
});

myMod.config(function(greetingProvider) {
  greetingProvider.setText("Howdy there, ");
});

myMod.run(function(greeting) {
  greeting('Ford Prefect');
});

Thanks

Providers are accessible only in configuration phase of application life cycle. Their specific purpose is to provide a way to configure the future service, which provider should return via this.$get method.

In your case it doesn't really feel like you need a provider, simple service (factory) would have been enough. Or your can make use of factory and add one more method set to change text variable, stored in closure.

The setText function is only exposed on your app.config. The only thing you'll have when you access the provider within your controller is what you've included inside the $get function.
