What is it?
* itools.uri -- an API to manage URIs, to identify and locate resources.
* itools.resources -- an abstraction layer over resources that let to
manage them with a consistent API, independently of where they are stored.
* itools.handlers -- resource handlers infrastructure (resource handlers are non persistent classes that add specific semantics to resources). This package also includes several handlers out of the box.
* itools.xml -- XML infrastructure, includes resource handlers for XML, XHTML and HTML documents. Plus the Simple Template Language.
* itools.i18n -- tools for language negotiation and text segmentation.
* itools.workflow -- represent workflows as automatons, objects can move from one state to another through transitions, classes can add specific semantics to states and transitions.
* itools.catalog -- An Index & Search engine.
What's new?
Resources - Now "get_resources" is an iterator that returns a resource (not a name) at a time. - Memory folders provide "get_atime".
Handlers
- Add the methods "get_handler_names", "get_handlers" and "has_handler".
- The methods "get_resource", "has_resource", "set_resource", etc. have
been removed. Access them throug the "resource" attribute, or use the
equivalent handler methods ("get_handler_names", etc).
- Now text handlers only must define the method "to_unicode", which now
accepts the optional parameter encoding.
- The methods "__str__" and "__unicode__" have been removed. Use instead
"to_str" and "to_unicode".
- Serialization and de-serialization code has been moved from "xml.Schema"
to "handlers.IO". Now the code serializes and de-serializes to and from
byte strings.XML
- The architecture has been cleaned and simplified, specially for attributes,
whose API has changed.
- The new method "traverse2" makes "walk" obsolete.
Simple Template Language - The "stl:if" and "stl:attributes" expressions accept the new "not" operator. This change makes the "stl:ifnot" statement obsolete.
Catalog
- Now the catalog follows the load/save logic. As a side effect the index
and unindex operation has been speeded up but a factor of 2, aproximately.
Workflow - Remove the "__init__" method from the "WorkflowAware" class to avoid conflicts with handler classes. Now the method "enter_workflow" must be called explicitly.
Documentation
- Re-write part of the introduction.
- Re-organize the handler chapters. Explain some things for the first time,
explain other things better.
