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.
