Is their a way to get all keys from angular-translate translations?

Question

I want to know if there is a way to get available languages from $translate service and if there is a way display all the keys available in it.

I want to write a small tool that can shows easily differences between multiple translation resources files (json files).

i18n/fr.json

{
  "title": "Mon titre",
  "summary": "Mon beau résumé",
  "submit": "Envoyer!" 
}

i18n/en.json

{
  "title": "My title",
  "summary": "My summary",
  "submit": "Submit!",
  "contact": "Contact"
}

At the end, I want something like that :

╔══════════════╦═════════════╦═════════════════╗
║     keys     ║     en      ║       fr        ║
╠══════════════╬═════════════╬═════════════════╣
║ home.contact ║ Contact     ║ ############### ║
║ home.submit  ║ Submit!     ║ Envoyer!        ║
║ home.summary ║ My  summary ║ Mon beau résumé ║
║ home.title   ║ My title    ║ Mon titre       ║
╚══════════════╩═════════════╩═════════════════╝

Answer 1

Yes, there is

$translateProvider.translations();

You should get something like the folllowing (as JSON)

{  
   "en":{  
      "PAGE.MAIN":"Main page",
      "PAGE.1":"Content page 1",
      "PAGE.2":"Content page 2"
   },
   "fi":{  
      "PAGE.MAIN":"Pääsivu",
      "PAGE.1":"Sisältösivu 1",
      "PAGE.2":"Sisältösivu 2"
   }
}
