Need some fallback for Namespace.

[Virbhadrasinh]

I have following JSON for language, Handlebars helper and HTML

1. JSON for language

   var resources = {
   "dev" : {
       "translation" : {
           "title" : "Mr."
       }
   },
   "en" : {
       "translation" : {
           "last" : "Chauhan"
       },
       "name" : {
           "second" : "Jashvantsinh"
       }
   },
   "en-US" : {
       "name" : {
           "first" : "Virbhadrasinh"
       }
   }
   };
   

2. Handlebars helper

   Handlebars.registerHelper('t', function(key, nameSpace ) {
     return $.i18n.t(key,nameSpace);
   });
   

3. HTML
   var nameSpace = {
   ns : 'name'
   };

   <div>
   <span>{{t "title" nameSpace}}</span>
   <span>{{t "first" nameSpace}}</span>
   <span>{{t "second" nameSpace}}</span>
   <span>{{t "last" nameSpace}}</span>
   </div>

Now, whenever i am trying to render this HTML, it will not give me values for keys "title" and "last" because they are not in "name" nameSpace.

So, i need some fallback which look into default nameSpace if key is not found in given nameSpace.

So, I added "found = translate(key);" inside last if condition of "_translate" function and its working fine but its recursive function call. So, it may affect the performance.

Code :

     if (found === undefined) {
            notfound = applyReplacement(notfound, options);
            notfound = applyReuse(notfound, options);
            //Added line for namespace fallback...
            found = translate(key);
     }

not sure if i like to add an recursive lookup. might add this as an option - but not yet to sure.

personally i prefer adding the namespace like this:

<div>
<span>{{t "title"}}</span>
<span>{{t "first"}}</span>
<span>{{t "name:second"}}</span>
<span>{{t "name:last"}}</span>
</div>

starting from v1.5.11 (release should be this week) you could set option fallbackToDefaultNS = true in init options to turn on this behaviour. (default is false)
