How do I convert Handlebars isEq helper to Spacebars in Meteor?

Question

I've had in my Meteor project handlebar helper:

Handlebars.registerHelper('isEq', function(v1, v2, options){
    if(v1 === v2){
        return options.fn(this);
    }else{
        return options.inverse(this);
    }
});

But after update to 0.8 and switch from handlebars to spacebars it is not working anymore - I've found in other stackoverflow topic that now I should change Handlebars.registerHelper to UI.registerHelper but it is still not working - anyone know how to implement this properly for spacebars?

Answer 1

You want to use it like the following?

{{#isEq 7 8}}
    They're equal!
{{else}}
    They're not equal :(
{{/isEq}}

From 0.8, block helpers are defined as templates. See https://github.com/meteor/meteor/tree/devel/packages/spacebars#custom-block-helpers

And I think you need to call it with keyword arguments ({{#isEq v1=7 v2=8}}). Although, you should be able to define isEq as an helper, and then use the #if block helper like {{#if isEq 7 8}}.
