Overview

Creating a block with Liquify is as simple as creating a Ruby class.

class FooBlock < Liquify::Block
  def bar(params)
   ...
  end

  def baz
   ...
  end
end 

Liquify.setup do |config|
  config.register_tag :foo_block, FooBlock
end

{% foo_block as: 'f' %}
  {{ f.bar 'arg1', key: 'value' }}
  {{ f.baz }}
{% endfoo_block %}

If you need wrapper content override the invoke method and call yield within it.
