Legacy Handlebars support
Handlebars and HSVT templates can be seamlessly mixed in a plugin.
You should not use Handlebars for new plugins, and Handlebars support will be removed from a future version of the platform. This documentation is to support existing Haplo plugins.
Some handlebars helpers are provided.
Plugin Handlebars helpers
Plugin objects implement a function to register a custom Handlebars helper for your templates.
function registerHandlebarsHelper(name, helperFunction)
Register a Handlebars helper function, making it available to all the templates rendered by this plugin.
