jsdef - templetor extensions to support javascript templating

jsdef extension adds a new block jsdef to templetor syntax. The jsdef block defines a template function and also generates an equivalent JavaScript function.

This extension works only with the development branch of web.py.

http://github.com/webpy/webpy

How to use

Tell web.py to use the extension.

import web
import jsdef

render = web.template.render("templates", extensions=[jsdef.extension])

Include jsdef.js in your site template.

And use jsdef in your templates.

$def with (page)

<h1>$page.title</h1>

$jsdef render_books(books):
    <ul>
        $for book in books:
            <li><a href="$book.key">$book.title</a></li>
    </ul>
            
<div class="books">
    $# Above jsdef block has defined render_books template function. Use it when rendering the template.
    $:render_books(page.books)
</div>
    
<script type="test/javascript">
    function update_books(books) {
        // Above jsdef block has generated javascript for render_books function. Use it at the client.
        document.getElementById("books").innerHTML = render_books(books);
    }
</script>

Caveats

This is just an attempt to drive JavaScript templating from Python. Features like multiple assignments, list slicing, list comprehensions won't work.

If you are using a python function inside the jsdef block, you need to provide the equivalent in JavaScript too. Some builtin functions are already provided by jsdef.js.
