Tutorial

SOLD OUT Building Web Sites with the Template Toolkit
Andy Wardley, Canon Research Centre Europe Ltd.

Track: Perl
Date: Tuesday, July 08
Time: 1:45pm - 5:15pm
Location: Salon H

Wardley's tutorial shows how the Template Toolkit can be used to help in the construction and ongoing maintenance of a typical web site.

He begins with a general introduction to the Template Toolkit and shows how web content can be constructed from simple, modular template components in order to apply a consistent user interface to each of the pages in a site. He demonstrates various components that generate navigation elements, including multi-level menus, a "breadcrumb trail" showing the current page position in the site structure, and a table of contents for each page. Wardley then goes on to show techniques for manipulating page content, giving examples of how non-HTML sources such as XML, POD and plain text can be transformed into HTML pages and integrated seamlessly into the web site.

The next section concentrates on various aspect of customization. He illustrates how different user interface styles can be applied to a site in a process known as "skinning," and looks at localization and other techniques for generating alternate views of the same site content.

The final section covers web application programming using the Template Toolkit, with an emphasis on creating a clear separation of concerns between presentation templates and application code. Wardley gives examples of how Perl code should be written in "back-end" scripts and/or "front-end" plugin modules and discusses the relative strengths and weaknesses of each approach. He concludes with examples of using the Template Toolkit in the larger context of a web application framework.
