I think Mason (http://masonhq.com) addresses these sorts of
needs. I believe it provides a cross between Php scripting for
perl and some features that would normally be found in an
Features: (http://www.masonhq.com/about/features.html :)
Simple embedded Perl syntax. Infuse your HTML pages with the full
power of Perl: variables, arrays and data structures,
conditionals, iteration, and the wide variety of freely available
Perl modules. (Docs)
Modular pages with components. Build pages from components that
call one another and pass values back and forth like subroutines.
Encapsulate common design elements (headers, footers, menus,
logos) into shared components that need only change once to
affect the whole site.
Parameter handling. Access GET/POST parameters directly as
lexical ("my") variables. Assign default values or trigger error
conditions when parameters are omitted. (Docs)
Templates and filters. Assign a common template, filter, or piece
of code to an entire site (or a particular section) with a single
well-placed file. (Docs)
Object-oriented techniques. Define your own methods and
attributes on pages; access them from templates for increased
Caching. Cache HTML and data, from small page elements to entire
pages or complex data structures. Automatically expire elements
after a certain time period or when a certain condition occurs.
Previewing. Using the built-in previewer application, review your
page under a variety of client and request conditions: browser
type, time of day, referer, etc. View a page trace with a
breakdown of which component is responsible for each piece of
Staging/production modes. Adjust configuration settings to
maximize ease of development on a staging server and raw
performance on a live server. (Docs)
I first looked at Mason for TWiki, but retrofitting looks like
quite a lot of work. See also
