i18n helpers

Hi,

I didn’t got it right how to make custom helpers to use i18n without using handlebars direct

im getting this error when i start my application.

exphbs.registerHelper('__', function () {
       ^
TypeError: undefined is not a function

Otherwise the templates are rendering just fine, so im must be doing almost everything ok… 😃

Figured it out! The solution simply consists in using the data.root.locale from the last argument of the helper.

app.use(function(req, res, next) {
  hbs.handlebars.registerHelper('i18n', function() {
    var args = Array.prototype.slice.call(arguments);
    var options = args.pop();
    return i18n.__.apply(options.data.root, args);
  });
  next();
});

using data.root.locale worked for me too. I however am only using it when this.locale is not set for optimization.

    if(!this.locale){
      var args = Array.prototype.slice.call(arguments)
      var options = args.pop()
      return i18n.__.apply(options.data.root, args)
    }
    return i18n.__.apply(this, arguments)
