Overview

If the HTML builder is given an ERB template, it uses this class to parse the ERB into HTML. Lifer project metadata is provided as context. For example:

<html>
  <head>
    <title><%= my_collection.name %></title>
  </head>

  <body>
    <h1><%= my_collection.name %></h1>

    <% my_collection.entries.each do |entry| %>
      <section>
        <h2><%= entry.title %></h2>
        <p><%= entry.summary %></p>
        <a href="<%= entry.permalink %>">Read more</a>
      </section>
    <% end %>
  </body>
</html>
