gNius is a 100% client-side Javascript template engine. It features numerous ways to iterate over Javascript objects, conditionally show markup, transform data, and more from within your HTML application.

A GTD-based task management program, Giddy, is provided as the sample or reference implementation.

Imagine you have a Javascript object (or JSON snippet):

var tasks = {
  'walk the dog': {done: true},
  'buy some groceries': {
    start: '12/21',
    tasks: {
      'get bread': {done:true},
      'get milk': {}
    }
  }
};

Then some HTML:

<table>
  <tr iterate="for task in tasks">
    <td>{task.done}</td>
    <td>{task.name} {task.tasks}</td>
    <td>{task.start}</td>
    <td>{task.end}</td>
  </tr>
</table>

gNius will find what it needs to find to make it look like you want it to look. It's smarter than its developers. We don't know how it works.
