Overview

A base component class that renders child components defined in a block into a String for further formatting.

class MyComponent < Eskimo::ASCII::Component
  def render(**)
    text = super
    text.is_a?(String) # => true
  end
end

Use of this class is optional. What's happening under the hood is:

1. Component maintains a reference to the Proc passed to #initialize. That Proc can potentially return a list of child components to render.

2. #render (called via "super" from sub-classes) invokes the render prop provided by Core::Renderer#apply with the tracked children which converts them to a String and returns them.
