Description :
Mason is a tool for building, serving and managing large web sites. Its
features make it an ideal backend for high load sites serving dynamic
content, such as online newspapers or database driven e-commerce sites.
Actually, Mason can be used to generate any sort of text, whether for a web
site or not. But it was originally built for web sites and since that\'s why
most people are interested in it, that is the focus of this documentation.
Mason\'s various pieces revolve around the notion of \"components\'\'. A
component is a mix of HTML, Perl, and special Mason commands, one component
per file. So-called \"top-level\" components represent entire web-pages,
while smaller components typically return HTML snippets for embedding in
top-level components. This object-like architecture greatly simplifies site
maintenance: change a shared component, and you instantly changed all
dependent pages that refer to it across a site (or across many virtual
sites).
Mason\'s component syntax lets designers separate a web page into
programmatic and design elements. This means the esoteric Perl bits can be
hidden near the bottom of a component, preloading simple variables for use
above in the HTML. In our own experience, this frees content managers
(i.e., non-programmers) to work on the layout without getting mired in
programming details. Techies, however, still enjoy the full power of Perl.
Mason works by intercepting innocent-looking requests (say,
http://www.yoursite.com/index.html) and mapping them to requests for Mason
components. Mason then compiles the component, runs it, and feeds the
output back to the client.
Consider this simple Mason component:
% my $noun = \'World\';
Hello < % $noun %>!
How are ya?
The output of this component is:
Hello World!
How are ya?
In this component you see a mix of standard HTML and Mason elements. The
bare \'%\' prefixing the first line tells Mason that this is a line of Perl
code. One line below, the embedded < % ... %> tag gets replaced with the
return value of its contents, evaluated as a Perl expression.
Beyond this trivial example, components can also embed serious chunks of
Perl code (say, to pull records from a database). They can also call other
components, cache results for later reuse, and perform all the tricks you
expect from a regular Perl program.
