Ophelia 0.3 has just been released. Ophelia creates XHTML pages from templates written in TAL, the Zope Tag Attribute Language. It is designed to reduce code repetition to zero. The package contains both a WSGI application running Ophelia as well as a request handler for mod_python, the Python module for the Apache2 web server. Additionally, a script is included that renders a page and dumps it to stdout, and another one that runs a wsgiref based HTTP server hosting Ophelia's WSGI application. Ophelia is released under the Zope Public License, version 2.1. To use Ophelia 0.3, you need Python 2.4. The mod_python request handler requires mod_python 3.3 or better. The package is available from the Python package index as a source distribution and a Python 2.4 egg: <http://cheeseshop.python.org/pypi/ophelia> The source code contains a zc.buildout configuration for an environment including Apache and mod_python. You can access the source code repository at <https://svn.thomas-lotze.de/repos/public/Ophelia/>, browse it using ViewCVS at <http://svn.thomas-lotze.de/svn-public/Ophelia/>, or visit Ophelia's web page, containing a commented live usage example, at <http://www.thomas-lotze.de/en/software/ophelia/>.

From the documentation:

What kind of sites is Ophelia good for? ======================================= Static content -------------- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflect in the file system organization of your documents; how templates combine is deduced from their places in the hierarchy of directories. Dynamic content --------------- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views don't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. -- Viele Grüße, Thomas
