Nevow's main focus is on separating the HTML template from both the
business logic and the display logic, while allowing the programmer
to write pure Python code as much as possible. It separates your code
into 'data' and 'render' functions, a simplified implementation of
traditional MVC. It has various parts which can be used individually
or as a whole, integrated web solution:
.
- XHTML templates: contain no programming logic, only nodes tagged
with nevow attributes
- data/render methods: simplified MVC
- stan: An s-expression-like syntax for expressing xml in pure Python
- formless: For describing the types of objects which may be passed
to methods of your classes, validating and coercing string input from
either web or command-line sources, and calling your methods
automatically once validation passes
- freeform: For rendering web forms based on formless type
descriptions, accepting form posts and passing them to formless
validators, and rendering error forms in the event validation fails
- livepage: Cross-browser JavaScript glue for sending client side
events to the server and server side events to the client after the
page has loaded, without causing the entire page to refresh
