- Nevow Glossary
- ==============
-
- Object Traversal
- The process by which a Python object is located to render HTML for a given
- HTTP URL. For example, given the URL http://example.com/foo/bar, Object
- Traversal will begin at the "Root Resource" object by asking it for an object
- which is capable of rendering the page at ('foo', 'bar'). The "Root Resource"
- returns an object and a list of unhandled path segments, and the traversal
- continues across this new Resource object until all path segments have been
- consumed.
-
- Page Rendering
- The process by which a Python object, usually a rend.Page subclass, turns
- itself into HTML. Page Rendering involves locating some page data, loading a
- template document, and applying the template to the data, in the process
- generating HTML.
-
- Deployment Environment
- The environment in which a Nevow application is deployed. Generally involves
- an HTTP server which is configured to route certain (or all) HTTP requests
- through the Nevow Object Traversal and Page Rendering process. Deployment
- environments include CGI, WSGI, and twisted.web.
-
- DOM
- Document Object Model. A tree of objects which represent the structure of an
- XHTML document in memory. Nevow uses a nonstandard DOM named "stan", which is
- made up of simple Python lists, dicts, strings, and nevow.stan.Tag instances.
-
- Flattener
- A Python function which knows how to translate from a rich type to a string
- containing HTML. For example, the integer flattener calls str() on the
- integer. The string flattener escapes characters which are unsafe in HTML,
- such as <, >, and &.
-
- Tag
- A class, defined at nevow.stan.Tag, which holds information about a single
- HTML tag in a DOM. Tag instances have three attributes: tagName, attributes,
- and children. tagName is a string indicating the tag name. attributes is a
- dict indicating the HTML attributes of that node. children is a list
- indicating the child nodes of that node.
-
- Tag Specials
- A Tag attribute which is "special" to nevow. Tag specials include data,
- render, pattern, slot, and macro. Tag Specials will never be output as HTML
- attributes of tags, but will be used by the internal Nevow rendering process
- to influence how the Tag is rendered.
