NAME
Template::Modules - Template Toolkit Modules
Template Toolkit Modules
This documentation provides an overview of the different modules that comprise the
Template Toolkit.
Template
The Template module is the front-end to the Template Toolkit for Perl programmers.
use Template;
my $tt = Template->new();
$tt->process('hello.html', message => 'Hello World');
Template::Base
The Template::Base module implements a base class from which the other Template Toolkit
modules are derived. It implements common functionality for creating objects, error
reporting, debugging, and so on.
Template::Config
The Template::Config module defines the configuration of the Template Toolkit for your
system. It is an example of a factory module which is responsible for instantiating the
various other modules used in the Template Toolkit.
For example, the Template::Config module defines the $STASH package variable which
indicates which version of the Template::Stash you are using by default. If you elected
to use the faster XS stash when you installed the Template Toolkit, then this will be set
as:
$STASH = 'Template::Stash::XS';
Otherwise you'll get the regular Perl stash:
$STASH = 'Template::Stash';
This approach means that other parts of the Template Toolkit don't have to worry about
which stash you're using. They just ask the Template::Config module to create a stash of
the right kind.
Template::Constants
The Template::Constants defines a number of constants that are used by the Template
Toolkit.
For example, the ":chomp" tagset defines the "CHOMP_???" constants that can be used with
the "PRE_CHOMP" and "POST_CHOMP" configuration options.
use Template::Constants ':chomp';
my $tt = Template->new({
PRE_CHOMP => CHOMP_COLLAPSE,
});
Template::Context
The Template::Context module defines a runtime context in which templates are processed. A
context keeps track of all the templates, variables, plugins, and other resources that are
available (either directly or through delegate objects) and provides methods to fetch,
store, and perform various operations on them.
Template::Document
The Template::Document module implements a compiled template document object. This is
generated by the Template::Parser module.
Template::Exception
The Template::Exception module implements an exception object which is used for runtime
error reporting.
Template::Filters
The Template::Filters module implements a filter provider. It includes the core
collection of filters that can be used via the "FILTER" directive.
Template::Iterator
The Template::Iterator module implements a data iterator which steps through each item in
a list in turn. It is used by the "FOREACH" directive. Within a "FOREACH" block, the
"loop" variable always references the current iterator object.
[% FOREACH item IN list;
IF loop.first;
# first item in loop
ELSIF loop.last;
# last item in loop
ELSE;
# any other item in loop
END;
END
%]
Template::Namespace::Constants
The Template::Namespace::Constants module is used internally to represent constants. These
can be resolved immediately at the point that a template is compiled.
Template::Parser
The Template::Parser module is used to parse a source template and turn it into Perl code
which can be executed.
Template::Plugin
The Template::Plugin module is a base class for Template Toolkit plugins that can be
loaded on demand from within a template using the "USE" directive.
Template::Plugins
The Template::Plugins module is the plugins provider. It loads and prepares plugins as
and when they are requested from within a template.
Template::Provider
The Template::Provider module is responsible for loading, compiling and caching templates.
Template::Service
The Template::Service module implements a service layer that sits just behind the Template
module, and just in front of a Template::Context. It handles each request to process a
template (forwarded from the Template module). It adds any headers and/or footers
(specified via the "PRE_PROCESS" and "POST_PROCESS" options), applies any wrapper (the
"WRAPPER" option) and catches any errors returned (the "ERRORS" option).
Template::Stash
The Template::Stash module is used to fetch and store template variables. It implements
all of the magic associated with the dot operator.
Template::Stash::XS
The Template::Stash::XS module is a high-speed implementation of Template::Stash written
in C.
Template::Test
The Template::Test module is used to automate the Template Toolkit test scripts.
