1 Nevow is a next-generation web application templating system, based on
2 the ideas developed in the Twisted Woven package. Its main focus is
3 on separating the HTML template from both the business logic and the
4 display logic, while allowing the programmer to write pure Python code
5 as much as possible. It separates your code into 'data' and 'render'
6 functions, a simplified implementation of traditional MVC. It has
7 various parts which can be used individually or as a whole, integrated
10 * XHTML templates: contain no programming logic, only nodes tagged
12 * data/render methods: simplified MVC
13 * stan: An s-expression-like syntax for expressing xml in pure python
14 * formless: For describing the types of objects which may be passed
15 to methods of your classes, validating and coercing string input
16 from either web or command-line sources, and calling your methods
17 automatically once validation passes
18 * freeform: For rendering web forms based on formless type
19 descriptions, accepting form posts and passing them to formless
20 validators, and rendering
21 * error forms in the event validation fails
22 * livepage: Cross-browser JavaScript glue for sending client side
23 events to the server and server side events to the client after the
24 page has loaded, without causing the entire page to refresh
