amrita - a html/xhtml template library for Ruby

Summary

Amrita is a a html/xhtml template library for Ruby. It makes html documents from a template and a model data.

Key feature

  • The template for amrita is a pure html/xhtml document without no special tag like <?…?> or <% .. %>
  • The template can be written by designers using almost any HTML Editor.
  • Need no change on Ruby code to change the view of dynamic part (not only static part) of the template
  • The model data may be standard Ruby data, Hash, Array, String… or an instance of a classes you made.
  • The output is controlled by data not by logic. So It’s easy to write, test, debug code. (Good for eXtreamPrograming)
  • HTML template can be compiled into Ruby code before execution with a little effort.

Amrita mixes a template and model data up to a html document naturally matching the id attribute of HTML element to model data.

template:

   <table border="1">
     <tr><th>name</th><th>author</th></tr>
     <tr id="table1">
       <td id="name"><td id="author">
     </tr>
   </table>

data:

   data = {
      :table1=>[
         { :name=>"Ruby", :author=>"matz" },
         { :name=>"perl", :author=>"Larry Wall" },
         { :name=>"python", :author=>"Guido van Rossum" },
      ]
   }

template + data = output:

  <table>
    <tr>
    <th>name</th>
    <th>author</th>
    </tr>
    <tr>
    <td>Ruby</td>
    <td>matz</td>
    </tr>
    <tr>
    <td>perl</td>
    .......

Credits

  • Thanks for many suggestions and contribution of Kaoru Shirai.
  • The html parser in amrita/parser.rb is based on work of MoonWolf.
  • sample/tour/rexml_doc.xml (sample data for sample/tour/xml3.rb) was editted from documentation.xml in rexml archive and xml format of docs/index.xml is based on it.
  • ams(AmritaScript) is based on the idea and sugestion by Mr.Beyond

ToDos and plans

  • AnyData doesn’t work well when it was used with other Hint.
  • a compiler that produces code with more speed and less flexibility

    (It’s difficult to take an appropriate trade-off and make a good interface)
