HTMLBars block helper
Have to work with it on latest Ember.js beta but documentation in Ember.js site have only inline helper. After digging for a whole day, found out that Ember.js changes the interface for new HTMLBars helper.
From current Handlebars helper method
gist:cc289fd8c0a5dd080442,helper1.js
It changes to
gist:cc289fd8c0a5dd080442,helper2.js
params is array containing Stream coming from 1.9.0. Each stream is a value passing from template.
hash, I don't know what's this argument yet. Currently what I get from my template is empty Object.
options Template option including morph for this tag are move to this argument.
env This is similar to old Ember.js option which contains DOM and data for this template.
I'm not fully understand all parameters yet and it's beta version. So all this options and interface might change in the future.
