Web application templating system, based on the Twisted Woven

Nevow pronounced as the French “nouveau”, or “noo-voh” is a web application construction kit written in Python. It is designed to allow the programmer to express as much of the view logic as desired in Python, and includes a pure Python XML expression syntax named stan to facilitate this. However it also provides rich support for designer-edited templates, using a very small XML attribute language to provide bi-directional template manipulation capability.

Nevow also includes formless, a declarative syntax for specifying the types of method parameters and exposing these methods to the web. Forms can be rendered automatically, and form posts will be validated and input coerced, rendering error pages if appropriate. Once a form post has validated successfully, the method will be called with the coerced values.
